The latter can develop into extrahepatic portal hypertension (PHT). It is difficult to establish the correct method for treating these conditions. METHODS: At another hospital, a 51-year-old man developed PHT as a result of endoscopic retrograde cholangiopancreatography and endoscopic nasobiliary drainage to relieve cholelithiasis and obstructive jaundice. We dealt with the biliary tract obstruction through percutaneous transhepatic cholangial drainage (PTCD), followed by selective devascularization and a shunt operation 2 weeks after the disappearance of jaundice. Three months after cholecystojejunostomy, there were no obvious changes around the bile duct. RESULT: The patient recovered uneventfully and was discharged 14 days after operation. CONCLUSION: For this patient, surgery in stages was the best choice. The most suitable method to decrease jaundice is PTCD.展开更多

Met...Objective: To evaluate the significance of intraopera- tive reassessment of liver function reserve in the se- lection of surgical procedures to optimize therapeutic results in the treatment of portal hypertension. Methods: The data of 146 patients with portal hyper- tension treated in the past 10 years were retrospec- tively reviewed. Posthepatitis cirrhosis was found in 118 patients, schistosomial cirrhosis in 6, alcoholic cirrhosis in 1, mixed cirrhosis in 5, and other disea- ses in 16. According to Child's criteria, 45 patients were classified into class A, 92 class B, and 9 class C. At operation, 33 patients were reclassified into class A, 78 class B, and 35 class C. Disconnection procedure was performed in 89 patients (61. 0%) and shunt procedure in 57 (39. 0 %). These opera- tions included prophylactic operations in 27 patients (18. 5 %) and emergency disconnection operations in 2 (1. 4%). Results: One patient (0. 7 %) died of upper gastroin- testinal bleeding during operation. Early rebleeding following operation occurred in 9 patients (6. 1%) (disconnection in 5 patients and shunt in 4). Early encephalopathy after operation occurred in 2 patients (1. 4 %) (disconnection in 1 patient and shunt in 1). A total of 98 patients (67. 6%) (disconnection in 61 patients and shunt in 37) were followed up (6 months to 9 years). Bleeding occurred again in 12 patients (12. 2 %) (disconnection in 9 patients and shunt in 3) 17 months after operation (4 to 41 months). Late encephalopathy occurred in 6 shunt patients at 19 months (3-40 months). The late re- bleeding rates of shunt patients and disconnection pa- tients were 8.1% (3/37 patients) and 14. 9 % (9/ 61) (P>0. 05) respectively. The late encephalopathy rates of shunt patients and disconnection patients were 16. 2% (6/37) and 0% (0/61) respectively (P <0. 01). Eight patients (5. 5 %) died of upper gas- trointestinal bleeding (2), hepatic failure (3), liver cancer (2), and rectal cancer (1) in the period of follow-up. Conclusions: The success and effectiveness of surgical procedures for portal hypertension are closely related to the status of patient's liver function reserve. In- tra-operative reassessment of hepatic function reserve is crucial. Selection of procedures based on patient's hepatic function reserve, local anatomical conditions and surgeon's experience would optimize therapeutic results.展开更多

Methods: Twenty patients with portal hypertension were divided into two groups (A, B), 10 patients per group. In group A, patients were treated with com- bined transjugular intrahepatic portosystemic shunt (TIPS) and modified Sugiura. In group B, patients were treated with modified Sugiura only. Intestinal permeability was assessed before operation, two weeks after TIPS. and two weeks after modified Sug- iura; 20 healthy control subjects were also assessed. Results: Intestinal permeability was significantly higher in the patients than in the control group (P< 0. 01). In group A, portal pressure, intestinal per- meability decreased two weeks after TIPS (P< 0. 05), and no obvious change was noted two weeks after modified Sugiura; but they were significantly lower than those before TIPS (P<0. 05). In group B, intestinal permeability was not different before and after operation. Intestinal permeability in group A was not different from that in group B before treatment, but significantly lower after modified Su- giura (P<0. 05). Portal pressure was significantly correlated with intestinal permeability (r=0. 627, P <0. 01). Conclusions: This study shows that combined TIPS and modified Sugiura can lower portal pressure and intestinal permeability, and enhance the therapeutic efficacy on portal hypertension.展开更多

Method The diagnosis had been confirmed by cardiac catheter before the operation, Pp/Ps (0. 81±0.09) and Rp (9.41 ±5.37 ) wood. Ventricular septal prothesis was performed under cardiopulmonary bypass. Transthoracic intracardiac monitoring line inserted into pulmonary artery in 117 cases. Results Fourteen cases died of the 144 postoperatively, with mortality of 9.12% . Preoperative Pp/Ps≥0. 8 and Rp≥10 wood made the mortality higher than that of others ( P < 0. 05 ) . 32 persons had post - operative SpPA > 50 mmHg among the survivors and among the children with preoperative Pp/Ps ≥0. 8 and Rp≥10 wood the mortality was 28. 6 % being higher than that among those with Pp/Ps≥0. 8 and Rp < 10 wood. Conclusion The higher the preoperative Pp/Ps and Rp are, the higher the surgical mortality is. The prevention and treatment of postoperative pulmonary hypertension crisis should be given more attention. The placement of transthoracic intracardiac monitoring lines plays an important role in the prevention and treatment of the complications occurring postoperationally in children with pulmonary hypertension.展开更多

Cavernomatous transformation of the portal vein is common after portal thrombosis in non-cirrhotic patients. This challenging situation is relatively more frequent after liver transplantation, particularly in pediatric recipients. Acute bleeding from esophageal and gastric varices is temporarily treated by sclerotherapy or variceal banding. Children who experience continued bleeding despite medical management or who experience clinically significant hypersplenism are referred for surgery.展开更多

In these cases, and when the patient’s BMI is high above 40 kg/m2, the weight of the breasts or abdomen produces what we consider suffocation when the patient is placed in horizontal position on surgical tables, decreasing his respiratory capacity and increasing the difficulty in treating respiratory or embolic risks. An 8-kg breast on the patient’s chest prevents normal breathing. An abdomen with a volume of 30 kg causes difficulties in all senses, making the physiological expansion of the lungs impossible and even preventing surgical assistance to patients. These patients are almost always customers who sleep in the sitting position to breathe better. The gigantic extirpation of the surgical parts facilitates a better respiratory expansion reducing by a large percentage the risk of death, what we call body relief. This relief does not free the patient from bariatric surgery for a possible weight loss, which is vital for the proper functioning of the organs and decreasing arterial hypertension and diabetes.展开更多

New, non invasive bedside monitors(pulse dye densitometry technology) make this opportunity widely available in clinical practice. After having reviewed basic concepts of hepatic clearance, we analysed the most common indications ICG kinetic parameters have nowadays in clinical practice, focusing in particular on the diagnostic and prognostic role of PDR and R15 in the perioperative period of major liver surgery and liver transplantation. As recently pointed out, even if of extreme interest, ICG clearance parameters have still some limitations, to be considered when using these tests.展开更多

METHODS: Totally 137 aged patients (149 eyes) underwent cataract operation in the case of stable systemic condition, the blood pressure less than 160/95mmHg, blood glucose less than 8mmol/L, and under the help of electrocardiogram surveillance by anesthesiologists during the operation. 106 aged patients (114 eyes) underwent Phaco while 31 aged patients (35 eyes) underwent SICS. The postoperative visual acuity, corneal endothelial cell loss, surgery time and major complications were observed and analyzed retrospectively. RESULTS: The best-corrected visual acuity (BCVA) of >= 0.6 was achieved in 135 eyes (92.6%) at 1 month postoperatively (chi(2)=259.730, P<0.001). For aged patients, both Phaco and SICS could significantly improve visual acuity with no significant difference (chi(2)=4.535, P > 0.05). Postoperative corneal endothelial cell loss was 18.6%, in PHACO group, the rate was 18.5%; in SICS group, the rate was 19.0%, the difference of which was no significant (chi(2)=0.102, P>0.05). The surgery time was different in two groups. No severe complications occurred. CONCLUSION: Both Phaco and SICS combined with IOL implantation for aged patients are effective and safe. Before surgery, detailed physical examination should be performed. When the systemic condition is stable, cataract surgery for aged patients is safe.展开更多

Bariatric surgery, a treatment approved for weight loss in morbidly obese patients, has reported to be associated with good outcomes, such as reversal of type two diabetes mellitus and reducing all-cause mortality on a long term basis. However, complications from bariatric surgery have similarly been reported. In particular, with the onslaught of non-alcoholic fatty liver disease(NAFLD) epidemic, in associated with obesity and metabolic syndrome, there is increasing prevalence of NAFLD related liver cirrhosis, which potentially connotes more risk of specific complications for surgery. Bariatric surgeons may encounter, either expectedly or unexpectedly, patients with non-alcoholic steatohepatitis(NASH) and NASH related cirrhosis more frequently. As such, the issues and considerations surrounding their medical care/surgery warrant careful deliberation to ensure the best outcomes. These considerations include severity of cirrhosis, liver synthetic function, portal hypertension and the impact of surgical factors. This review explores these considerations comprehensively and emphasizes the best approach to managing cirrhotic patients in the context of bariatric surgery.展开更多

Methods A total of 180 essential hypertension patients were enrolled in our study. The determination of plasma Ang Ⅱ concentration, ambulatory blood pressure (ABP), and polysomnography (PSG) monitoring were performed before and 3 months after CPAP or surgical treatment. Results Patients were classified into three groups by their apnea-hypopnea index (AHI): essential hypertension group (EH group, n=72; AHI〈5), essential hypertension with mild SAS group (EH+mild SAS group, n=60, 5≤AHI〈20), and essential hypertension with moderate and severe SAS group (EH+moderate-severe SAS group, n=48, AHI_〉20). The concentrations of plasma AngⅡ in the above three groups were 13.42±3.27, 16.17±3.82, and 18.73±4.05 ng/mL respectively before treatment, and AngⅡ concentration in EH patients combined with SAS was significantly higher than that in EH group (all P〈0.05). After treatment the values in the latter two groups significantly decreased to 14.67±2.56 and 15.03±3.41 ng/mL respectively (P〈0.05). The incidence of non-dipper blood pressure curve in EH patients was 31.9%, and those in hypertensive patients with mild SAS and moderate-severe SAS were 51.7% and 58.3%, respectively before treatment. The incidence of non-dipper blood pressure curve in the EH patients with mild SAS was significantly higher than that of patients with EH alone (P〈0.05). After CPAP treatment or surgery, the incidence of non-dipper blood pressure curve in the two SAS groups was significantly decreased to 38.3% and 39.6%, respectively (P〈0.05). Conclusions Ang Ⅱ might play a role in blood pressure variability in patients with obstructive SAS. CPAP or surgical treatment can improve blood pressure disorder and decrease plasma Ang Ⅱ level in patients with obstructive SAS.展开更多

There was no classification of the degree of obesity by the body mass index (BMI) as we have today. By chance, on a Saturday in June 1975, at the Outpatient Clinic of the 23rd Infirmary of Santa Casa da Misericórdia Hospital in Rio de Janeiro, arrived the patient I. S., 41 years old, 1.70 m tall, supported by her two children, weighing 210 kg in weight body. Knowing that bariatric surgery only appeared in the 1980s, before that, patients with morbid obesity were left to their own devices, with hypertension and diabetes. The patient I. S. was hospitalized for 3 years in our Plastic Surgery Service, having received nutritional monitoring, had sporadic discharges and undergone 9 reparative plastic surgeries. She was discharged weighing 71 kg, with self-esteem recovered and happy to start a new life, without hypertension and diabetes.展开更多
文摘This review summarizes the definition and surgical methods of oncometabolic surgery according to previous studies.Then,the authors discuss the beneficial effects observed after gastrectomy in gastric cancer(GC)patients with concurrent hypertension or type 2 diabetes mellitus(T2DM).The authors summarize the current studies analyzing the remission rate and the hypotheses of the mechanisms underlying these effects.The remission rate ranged from 42.5%-65.4%in T2DM patients and from 11.1%-57.6%among those with hypertension.Furthermore,the remission of T2DM could have an impact on overall survival rates as well.The mechanisms underlying the remission of hypertension and T2DM is unclear in current studies,but oncometabolic surgery is expected to be applied in clinical practice.In addition,the effect of oncometabolic surgery on other chronic metabolic comorbidities is expected to be proven in further studies.Therefore,the purpose of this review is to discuss the effects of oncometabolic surgery reported in current studies with a primary focus on the remission of hypertension and T2DM after gastrectomy in GC patients.The possibility of the remission of other metabolic comorbidities in GC patients who undergo oncometabolic surgery is also discussed.
文摘Left-side portal hypertension(LSPH)is a rare cause of intraabdominal venous hypertension.In most of cases,LSPH is due to pancreatic diseases,especially chronic pancreatitis,but it is also described in other abdominal diseases(i.e.,retroperitoneal fibrosis or perineal abscess)after abdominal surgery(i.e.,pancreatic surgery,liver transplantation)or endovascular procedures[1–4].
文摘BACKGROUND: Recurrence of inflammation in the extrahepatic bile duct can lead to bile duct stenosis' obstructive jaundice and cavernous transformation of the portal vein. The latter can develop into extrahepatic portal hypertension (PHT). It is difficult to establish the correct method for treating these conditions. METHODS: At another hospital, a 51-year-old man developed PHT as a result of endoscopic retrograde cholangiopancreatography and endoscopic nasobiliary drainage to relieve cholelithiasis and obstructive jaundice. We dealt with the biliary tract obstruction through percutaneous transhepatic cholangial drainage (PTCD), followed by selective devascularization and a shunt operation 2 weeks after the disappearance of jaundice. Three months after cholecystojejunostomy, there were no obvious changes around the bile duct. RESULT: The patient recovered uneventfully and was discharged 14 days after operation. CONCLUSION: For this patient, surgery in stages was the best choice. The most suitable method to decrease jaundice is PTCD.
文摘AIM:To analyze the outcome of hepatocellular car-cinoma(HCC)resection in cirrhosis patients,related to presence of portal hypertension(PH)and extent of hepatectomy.METHODS:A retrospective analysis of 135 patients with HCC on a background of cirrhosis was submitted to curative liver resection.RESULTS:PH was present in 44(32.5%)patients.Overall mortality and morbidity were 2.2% and 33.7%,respectively.Median survival time in patients with or without PH was 31.6 and 65.1 mo,respectively(P=0.047);in the subgroup with Child-Pugh class A cirrhosis,median survival was 65.1 mo and 60.5 mo,respectively(P=0.257).Survival for patients submitted to limited liver resection was not significantly different in presence or absence of PH.Conversely,median survival for patients after resection of 2 or more segments with or without PH was 64.4 mo and 163.9 mo,respectively(P=0.035).CONCLUSION:PH is not an absolute contraindication to liver resection in Child-Pugh class A cirrhotic patients,but resection of 2 or more segments should not be recommended in patients with PH.
文摘BACKGROUND Portal hypertension(PH)is associated with changes in vascular structure and function of the portosplenomesenteric system(PSMS).This is referred to as portal hypertensive vasculopathy.Pathological abnormalities of PSMS has been described in the literature for cirrhotic patients.Raised portal pressure and hyperdynamic circulation are thought to be the underlying cause of this vasculopathy.In view of this,it is expected that pathological changes in splenic and portal vein similar to those reported in cirrhotic patients with PH may also be present in patients with non-cirrhotic PH(NCPH).AIM To investigate pathological abnormalities of splenic vein in patients with NCPH,and suggest its possible implications in the management of PH.METHODS A prospective observational study was performed on 116 patients with NCPH[Extrahepatic portal vein obstruction(EHPVO):53 and non-cirrhotic portal fibrosis(NCPF):63]who underwent proximal splenorenal shunt(PSRS),interposition shunt or splenectomy with devascularization in JIPMER,Pondicherry,India,a tertiary level referral center,between 2011-2016.All patients were evaluated by Doppler study of PSMS,computed tomography portovenogram and upper gastrointestinal endoscopy.An acoustic resonance forced impulse(ARFI)scan and abdomen ultrasound were done for all cases to exclude cirrhosis.Intraoperative and histopathological assessment of the harvested splenic vein was performed in all.The study group was divided into delayed and early presentation based on the median duration of symptoms(i.e.108 mo).RESULTS The study group comprising of 116 patients[77(66%)females and 39(34%)males]with NCPH had a median age of 22 years.Median duration of symptoms was 108 mo.The most common presentation in both EHPVO and NCPF patients was upper gastrointestinal bleeding(hematemesis and melena).The ARFI scan revealed a median score of 1.2(1.0-1.8)m/s for EHPVO and 1.5(0.9-2.8)m/s for NCPF.PSRS was performed in 84 patients(two of whom underwent interposition PSRS using a 10 mm Dacron graft);splenoadrenal shunt in 9;interposition mesocaval shunt in 5;interposition 1st jejunal to caval shunt in 1 patient and devascularization with splenectomy in 17 patients.Median presplenectomy portal pressure was 25(range:15-51)mm Hg.In 77%cases,the splenic vein was abnormal upon intraoperative assessment.Under macroscopic examination,wall thickening was observed in 108(93%),venous thrombosis in 32(28%)and vein wall calcification in 27(23%)cases.Upon examination under a surgical magnification loupe,21(18%)patients had intimal defects in the splenic vein.Histopathological examination of veins was abnormal in all cases.Medial hypertrophy was noted in nearly all patients(107/116),while intimal fibrosis was seen in 30%.Ninety one percent of patients with intimal fibrosis also had venous thrombosis.Vein wall calcification was found in 22%,all of whom had intimal fibrosis and venous thrombosis.The proportion of patients with pathological abnormalities in the splenic vein were significantly greater in the delayed presentation group as compared to the early presentation group.CONCLUSION Pathological changes in the splenic vein similar to those in cirrhotic patients with PH are noted in NCPH.We recommend that PH in NCPH be treated as systemic and pulmonary hypertension equivalent in the gastrointestinal tract,and that early aggressive therapy be initiated to reduce portal pressure and hemodynamic stress to avoid potential lethal effects.
文摘Objective: To evaluate the significance of intraopera- tive reassessment of liver function reserve in the se- lection of surgical procedures to optimize therapeutic results in the treatment of portal hypertension. Methods: The data of 146 patients with portal hyper- tension treated in the past 10 years were retrospec- tively reviewed. Posthepatitis cirrhosis was found in 118 patients, schistosomial cirrhosis in 6, alcoholic cirrhosis in 1, mixed cirrhosis in 5, and other disea- ses in 16. According to Child's criteria, 45 patients were classified into class A, 92 class B, and 9 class C. At operation, 33 patients were reclassified into class A, 78 class B, and 35 class C. Disconnection procedure was performed in 89 patients (61. 0%) and shunt procedure in 57 (39. 0 %). These opera- tions included prophylactic operations in 27 patients (18. 5 %) and emergency disconnection operations in 2 (1. 4%). Results: One patient (0. 7 %) died of upper gastroin- testinal bleeding during operation. Early rebleeding following operation occurred in 9 patients (6. 1%) (disconnection in 5 patients and shunt in 4). Early encephalopathy after operation occurred in 2 patients (1. 4 %) (disconnection in 1 patient and shunt in 1). A total of 98 patients (67. 6%) (disconnection in 61 patients and shunt in 37) were followed up (6 months to 9 years). Bleeding occurred again in 12 patients (12. 2 %) (disconnection in 9 patients and shunt in 3) 17 months after operation (4 to 41 months). Late encephalopathy occurred in 6 shunt patients at 19 months (3-40 months). The late re- bleeding rates of shunt patients and disconnection pa- tients were 8.1% (3/37 patients) and 14. 9 % (9/ 61) (P>0. 05) respectively. The late encephalopathy rates of shunt patients and disconnection patients were 16. 2% (6/37) and 0% (0/61) respectively (P <0. 01). Eight patients (5. 5 %) died of upper gas- trointestinal bleeding (2), hepatic failure (3), liver cancer (2), and rectal cancer (1) in the period of follow-up. Conclusions: The success and effectiveness of surgical procedures for portal hypertension are closely related to the status of patient's liver function reserve. In- tra-operative reassessment of hepatic function reserve is crucial. Selection of procedures based on patient's hepatic function reserve, local anatomical conditions and surgeon's experience would optimize therapeutic results.
文摘Objective: To investigate intestinal permeability in patients with portal hypertension and its relationship with portal pressure. Methods: Twenty patients with portal hypertension were divided into two groups (A, B), 10 patients per group. In group A, patients were treated with com- bined transjugular intrahepatic portosystemic shunt (TIPS) and modified Sugiura. In group B, patients were treated with modified Sugiura only. Intestinal permeability was assessed before operation, two weeks after TIPS. and two weeks after modified Sug- iura; 20 healthy control subjects were also assessed. Results: Intestinal permeability was significantly higher in the patients than in the control group (P< 0. 01). In group A, portal pressure, intestinal per- meability decreased two weeks after TIPS (P< 0. 05), and no obvious change was noted two weeks after modified Sugiura; but they were significantly lower than those before TIPS (P<0. 05). In group B, intestinal permeability was not different before and after operation. Intestinal permeability in group A was not different from that in group B before treatment, but significantly lower after modified Su- giura (P<0. 05). Portal pressure was significantly correlated with intestinal permeability (r=0. 627, P <0. 01). Conclusions: This study shows that combined TIPS and modified Sugiura can lower portal pressure and intestinal permeability, and enhance the therapeutic efficacy on portal hypertension.
文摘Left main coronary compression syndrome(LMCS)may complicate pulmonary artery aneurysms(PAA),usually developed in the context of pulmonary arterial hypertension(PAH).We report the case of a 51-year-old female patient with an atrial septal defect(unsuitable for device closure)complicated by a PAA generating a 90%left main stenosis.The significant PAH held us back from immediate surgery.After specific dual PAH-targeted therapy(sildenafil and bosentan),the atrial septal defect could be closed with a unidirectional valved patch;the PAAinduced LMCS was treated by reductive arterioplasty.The postoperative course was uneventful.Follow-up showed clinical improvement,but PAH treatment was still needed.After three months,coronary angiography showed only an insignificant residual left main stenosis,proving that reductive pulmonary arterioplasty was effective in treating LMCS.Any PAA requires further evaluation for LMCS,a dangerous but treatable complication.The“treat-repair-treat”strategy and shunt-closure with a unidirectional valved patch can both improve surgical prospects of LMCS with shunt-related PAH.
文摘Objective To report the result of surgical treatment for 144 children with ventricular septal defect and severe pulmonary hypertension. Method The diagnosis had been confirmed by cardiac catheter before the operation, Pp/Ps (0. 81±0.09) and Rp (9.41 ±5.37 ) wood. Ventricular septal prothesis was performed under cardiopulmonary bypass. Transthoracic intracardiac monitoring line inserted into pulmonary artery in 117 cases. Results Fourteen cases died of the 144 postoperatively, with mortality of 9.12% . Preoperative Pp/Ps≥0. 8 and Rp≥10 wood made the mortality higher than that of others ( P < 0. 05 ) . 32 persons had post - operative SpPA > 50 mmHg among the survivors and among the children with preoperative Pp/Ps ≥0. 8 and Rp≥10 wood the mortality was 28. 6 % being higher than that among those with Pp/Ps≥0. 8 and Rp < 10 wood. Conclusion The higher the preoperative Pp/Ps and Rp are, the higher the surgical mortality is. The prevention and treatment of postoperative pulmonary hypertension crisis should be given more attention. The placement of transthoracic intracardiac monitoring lines plays an important role in the prevention and treatment of the complications occurring postoperationally in children with pulmonary hypertension.
文摘Extrahepatic or prehepatic portal vein cavernoma and thrombosis is a more common condition in children than that in adult patients with extrahepatic or prehepatic portal vein obstruction (EHPVO), which involves approximately 30% of children with portal hypertension and can involve all the portal hypertension complications. Cavernomatous transformation of the portal vein is common after portal thrombosis in non-cirrhotic patients. This challenging situation is relatively more frequent after liver transplantation, particularly in pediatric recipients. Acute bleeding from esophageal and gastric varices is temporarily treated by sclerotherapy or variceal banding. Children who experience continued bleeding despite medical management or who experience clinically significant hypersplenism are referred for surgery.
文摘Depending on the treatment and weight of the breasts or abdomen, they may exceed volumes considered giant and morbidly obese. In these cases, and when the patient’s BMI is high above 40 kg/m2, the weight of the breasts or abdomen produces what we consider suffocation when the patient is placed in horizontal position on surgical tables, decreasing his respiratory capacity and increasing the difficulty in treating respiratory or embolic risks. An 8-kg breast on the patient’s chest prevents normal breathing. An abdomen with a volume of 30 kg causes difficulties in all senses, making the physiological expansion of the lungs impossible and even preventing surgical assistance to patients. These patients are almost always customers who sleep in the sitting position to breathe better. The gigantic extirpation of the surgical parts facilitates a better respiratory expansion reducing by a large percentage the risk of death, what we call body relief. This relief does not free the patient from bariatric surgery for a possible weight loss, which is vital for the proper functioning of the organs and decreasing arterial hypertension and diabetes.
文摘BACKGROUND:The incidence of hypertensive intracerebral hemorrhage(HICH)has been increasing during the recent years in low-and middle-income countries.With high mortality and morbidity rates,it brings huge burden to the families.It lacks evidence regarding the application of intracranial pressure(ICP)monitoring in HICH.In the current study,the authors aimed to evaluate whether ICP monitoring could make any difference on the prognosis of HICH patients after minimally invasive surgery.METHODS:A retrospective review of 116 HICH patients admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine,between 2014 and 2016,was performed.The effects of ICP monitoring on 6-month mortality and favorable outcomes were evaluated by univariate and logistic regression analysis.RESULTS:ICP monitors were inserted into 50 patients.Patients with ICP monitoring had a significantly better outcome(P<0.05).The average in-hospital duration in patients with ICP monitoring was shorter than that in the patients without ICP monitoring(16.68 days vs.20.47 days,P<0.05).Mortality rates between ICP monitoring and no ICP monitoring did not differ significantly(16.0%vs.15.1%,P=0.901).On univariate analysis,age,Glasgow Coma Scale(GCS)on admission and presence of ICP monitor were independent predictors of 6-month favorable outcomes.CONCLUSION:ICP monitoring is associated with a better 6-month functional outcome compared with no ICP monitoring.Future study is still needed to confirm our results and elucidate which subgroup of HICH patients will benefit most from the minimally invasive surgical intervention and ICP monitoring.
文摘BACKGROUND Hypertensive intracerebral hemorrhage is a common critical disease of the nervous system,comprising one fifth of all acute cerebrovascular diseases and has a high disability and mortality rate.It severely affects the patients’quality of life.AIM To analyze the short-term effect and long-term prognosis of neuroendoscopic minimally invasive surgery for hypertensive intracerebral hemorrhage.METHODS From March 2018 to May 2020,118 patients with hypertensive intracerebral hemorrhage were enrolled in our study and divided into a control group and observation group according to the surgical plan.The control group used a hard-channel minimally invasive puncture and drainage procedure.The observation group underwent minimally invasive neuroendoscopic surgery.The changes in the levels of serum P substances(SP),inflammatory factors[tumor necrosis factor-α,interleukin-6(IL-6),IL-10],and the National Hospital Stroke Scale(NIHSS)and Barthel index scores were recorded.Surgery related indicators and prognosis were compared between the two groups.RESULTS The operation time(105.26±28.35)of the observation group was min longer than that of the control group,and the volume of intraoperative bleeding was 45.36±10.17 mL more than that of the control group.The hematoma clearance rates were 88.58%±4.69%and 94.47%±4.02%higher than those of the control group at 48 h and 72 h,respectively.Good prognosis rate(86.44%)was higher in the observation group than in the control group,and complication rate(5.08%)was not significantly different from that of the control group(P>0.05).The SP level and Barthel index score of the two groups increased(P<0.05)and the inflam-matory factors and NIHSS score decreased(P<0.05).The cytokine levels,NIHSS score,and Barthel index score were better in the observation group than in the control group(P<0.05).CONCLUSION Neuroendoscopic minimally invasive surgery is more complicated than hard channel minimally invasive puncture drainage in the treatment of hypertensive intracerebral hemorrhage;however,hematoma clearance is more thorough,and the short-term effect and long-term prognosis are better than hard channel minimally invasive puncture drainage.
文摘Indocyanine green(ICG) kinetics(PDR/R15) used to quantitatively assess hepatic function in the perioperative period of major resective surgery and liver transplantation have been the object of an extensive, updated and critical review. New, non invasive bedside monitors(pulse dye densitometry technology) make this opportunity widely available in clinical practice. After having reviewed basic concepts of hepatic clearance, we analysed the most common indications ICG kinetic parameters have nowadays in clinical practice, focusing in particular on the diagnostic and prognostic role of PDR and R15 in the perioperative period of major liver surgery and liver transplantation. As recently pointed out, even if of extreme interest, ICG clearance parameters have still some limitations, to be considered when using these tests.
文摘AIM: To evaluate the effects and safety of phacoemulsification (Phaco) or small-incision extracapsular cataract surgery (SICS) and intraocular lens (IOL) implantation for aged patients. METHODS: Totally 137 aged patients (149 eyes) underwent cataract operation in the case of stable systemic condition, the blood pressure less than 160/95mmHg, blood glucose less than 8mmol/L, and under the help of electrocardiogram surveillance by anesthesiologists during the operation. 106 aged patients (114 eyes) underwent Phaco while 31 aged patients (35 eyes) underwent SICS. The postoperative visual acuity, corneal endothelial cell loss, surgery time and major complications were observed and analyzed retrospectively. RESULTS: The best-corrected visual acuity (BCVA) of >= 0.6 was achieved in 135 eyes (92.6%) at 1 month postoperatively (chi(2)=259.730, P<0.001). For aged patients, both Phaco and SICS could significantly improve visual acuity with no significant difference (chi(2)=4.535, P > 0.05). Postoperative corneal endothelial cell loss was 18.6%, in PHACO group, the rate was 18.5%; in SICS group, the rate was 19.0%, the difference of which was no significant (chi(2)=0.102, P>0.05). The surgery time was different in two groups. No severe complications occurred. CONCLUSION: Both Phaco and SICS combined with IOL implantation for aged patients are effective and safe. Before surgery, detailed physical examination should be performed. When the systemic condition is stable, cataract surgery for aged patients is safe.
文摘With the ever increasing global obesity pandemic, clinical burden from obesity related complications are anticipated in parallel. Bariatric surgery, a treatment approved for weight loss in morbidly obese patients, has reported to be associated with good outcomes, such as reversal of type two diabetes mellitus and reducing all-cause mortality on a long term basis. However, complications from bariatric surgery have similarly been reported. In particular, with the onslaught of non-alcoholic fatty liver disease(NAFLD) epidemic, in associated with obesity and metabolic syndrome, there is increasing prevalence of NAFLD related liver cirrhosis, which potentially connotes more risk of specific complications for surgery. Bariatric surgeons may encounter, either expectedly or unexpectedly, patients with non-alcoholic steatohepatitis(NASH) and NASH related cirrhosis more frequently. As such, the issues and considerations surrounding their medical care/surgery warrant careful deliberation to ensure the best outcomes. These considerations include severity of cirrhosis, liver synthetic function, portal hypertension and the impact of surgical factors. This review explores these considerations comprehensively and emphasizes the best approach to managing cirrhotic patients in the context of bariatric surgery.
文摘Objective To explore the changes in plasma angiotensin II (Ang Ⅱ) and circadian rhythm of blood pressure among hypertensive patients with sleep apnea syndrome (SAS) before and after continuous positive airway pressure (CPAP) or surgical treatment. Methods A total of 180 essential hypertension patients were enrolled in our study. The determination of plasma Ang Ⅱ concentration, ambulatory blood pressure (ABP), and polysomnography (PSG) monitoring were performed before and 3 months after CPAP or surgical treatment. Results Patients were classified into three groups by their apnea-hypopnea index (AHI): essential hypertension group (EH group, n=72; AHI〈5), essential hypertension with mild SAS group (EH+mild SAS group, n=60, 5≤AHI〈20), and essential hypertension with moderate and severe SAS group (EH+moderate-severe SAS group, n=48, AHI_〉20). The concentrations of plasma AngⅡ in the above three groups were 13.42±3.27, 16.17±3.82, and 18.73±4.05 ng/mL respectively before treatment, and AngⅡ concentration in EH patients combined with SAS was significantly higher than that in EH group (all P〈0.05). After treatment the values in the latter two groups significantly decreased to 14.67±2.56 and 15.03±3.41 ng/mL respectively (P〈0.05). The incidence of non-dipper blood pressure curve in EH patients was 31.9%, and those in hypertensive patients with mild SAS and moderate-severe SAS were 51.7% and 58.3%, respectively before treatment. The incidence of non-dipper blood pressure curve in the EH patients with mild SAS was significantly higher than that of patients with EH alone (P〈0.05). After CPAP treatment or surgery, the incidence of non-dipper blood pressure curve in the two SAS groups was significantly decreased to 38.3% and 39.6%, respectively (P〈0.05). Conclusions Ang Ⅱ might play a role in blood pressure variability in patients with obstructive SAS. CPAP or surgical treatment can improve blood pressure disorder and decrease plasma Ang Ⅱ level in patients with obstructive SAS.
文摘Before the 70s, in Brazil, each city had its morbidly obese, considered as the “excessive fats”, in very small numbers if we compare it with the current percentage. There was no classification of the degree of obesity by the body mass index (BMI) as we have today. By chance, on a Saturday in June 1975, at the Outpatient Clinic of the 23rd Infirmary of Santa Casa da Misericórdia Hospital in Rio de Janeiro, arrived the patient I. S., 41 years old, 1.70 m tall, supported by her two children, weighing 210 kg in weight body. Knowing that bariatric surgery only appeared in the 1980s, before that, patients with morbid obesity were left to their own devices, with hypertension and diabetes. The patient I. S. was hospitalized for 3 years in our Plastic Surgery Service, having received nutritional monitoring, had sporadic discharges and undergone 9 reparative plastic surgeries. She was discharged weighing 71 kg, with self-esteem recovered and happy to start a new life, without hypertension and diabetes.
