Difficulty removing a totally implantable venous access port:A case report

BACKGROUND This case report examines the challenges associated with removing a totally implantable venous access port(TIVAP)used for long-term chemotherapy in a patient with breast cancer.Prolonged use of TIVAPs can result in complications such as catheter kinking,thrombosis,and adhesions between the catheter and surrounding tissues,potentially complicating their removal.CASE SUMMARY A breast cancer patient with bone metastasis presented with difficulty aspirating blood from a TIVAP that had been placed in the right internal jugular vein for 3 years.Initial removal attempts at the Department of Venous Access Center were unsuccessful,likely due to adhesions,necessitating a subsequent successful catheter extraction in a hybrid operating room.Imaging revealed no abnor-malities,and the catheter was removed using a mosquito clamp to detach it from surrounding tissues.CONCLUSION This case highlights the challenges of removing TIVAPs inserted via the internal jugular vein,particularly when the catheter traverses the sternocleidomastoid muscle.Repeated neck movements might lead to significant adhesions around the catheter,complicating its removal.Careful consideration should be given during catheter placement to avoid muscle-related adhesions and facilitate smoother extraction in long-term use.

Potential applications of single-incision laparoscopic totally preperitoneal hernioplasty

BACKGROUND The totally preperitoneal(TPP)approach is a new concept that was recently introduced.Although the TPP approach combined with single-incision laparoscopic hernia repair has its own advantages,there is little evidence reflecting the characteristics and feasibility of either approach.AIM To analyze the potential applications of single-incision laparoscopic TPP(SILTPP)inguinal hernia hernioplasty for the treatment of inguinal hernias.METHODS A total of 152 SIL-TPP surgeries were performed at the First Affiliated Hospital of Ningbo University from February 2019 to November 2022.A single-port,named Iconport,and standard laparoscopic instruments were used during the operation.Demographic data,intraoperative parameters and short-term postoperative outcomes were collected and retrospectively analyzed.RESULTS The demographic data of 152 patients underwent SIL-TPP were shown in Table 1.The average age was 49.5 years(range from 21 to 81 years).The average body mass index was 27.7 kg/m^(2)(range from 17.7 kg/m^(2) to 35.6 kg/m^(2)).SIL-TPP were conducted successfully in 147 patients.Three patients were converted to the SILtransabdominal preperitoneal laparoscopic herniorrhaphy at the initial stage of the study due to a lack of experience.In 2 patients with incisional hernias,an auxiliary operation hole was added during the SIL-TPP procedure,as required for surgery.The mean operative time was 64.5 minutes(range:36.0-110.0 minutes)for unilateral direct and femoral hernias and 81.6 minutes for indirect hernias(range:40.0-150.0 minutes).The mean postoperative hospital stay was 3.4 days.CONCLUSION SIL-TPP is feasible and has advantages for inguinal hernia repair.SIL-TPP has potential benefits for patients with various abdominal wall hernias.Consequently,doctors should be encouraged to actively apply the TPP approach combined with a single incision in their daily work.

Comparative efficacy analysis of laparoscopic-assisted transanal total mesorectal excision vs laparoscopic transanal mesorectal excision for low-lying rectal cancer

BACKGROUND With the continuous development of laparoscopic techniques in recent years,laparoscopic total mesorectal excision(LapTME)and laparoscopic-assisted transanal total mesorectal excision(TaTME)have gradually become important surgical techniques for treating low-lying rectal cancer(LRC).However,there is still controversy over the efficacy and safety of these two surgical modalities in LRC treatment.AIM To compare the efficacy of LapTME vs TaTME in patients with LRC.METHODS Ninety-four patients with LRC who visited and were treated at the Affiliated Hengyang Hospital of Hunan Normal University&Hengyang Central Hospital between December 2022 and March 2024 were selected and divided into the LapTME(n=44)and TaTME(n=50)groups.Clinical operation indexes,postoperative recovery indicators,and postoperative complications were recorded.The anal resting pressure(ARP),anal maximum systolic pressure(MSP),and maximum tolerated volume(MTV)of the anal canal were also measured.The intestinal function of patients was evaluated by the Memorial Sloan Kettering Cancer Center(MSKCC)bowel function questionnaire.Serum norepinephrine(NE),adrenaline(AD),and cortisol(Cor)levels were measured.The Quality of Life Questionnaire Core 30(QLQC30)was used for quality of life assessment.RESULTS Compared with the LapTME group,the surgery time in the TaTME group was longer;intraoperative blood loss was low;time of anal exhaust,first postoperative ambulation,intestinal recovery,and hospital stay were shorter;and the distal incisal margin and specimen lengths were longer.The TaTME group also showed higher ARP,MSP,and MTV values and higher MSKCC and QLQ-C30 scores than the LapTME group 3 months postoperatively.Cor,AD,and NE levels were lower in the TaTME group than those in the LapTME group during recovery.CONCLUSION We demonstrated that TaTME better improved anal function,reduced postoperative stress,and accelerated postoperative recovery and,hence,was safer for patients with LRC.

Preoperative serum total bilirubin-albumin ratio as a prognostic indicator in patients with hepatitis-related cirrhosis after splenectomy

BACKGROUND Splenectomy is an effective yet invasive intervention for alleviating portal pressure in patients with hepatitis cirrhosis.However,the current prognostic indicators for predicting long-term overall survival of these patients have several limitations.AIM To assess the potential of preoperative total bilirubin-albumin(B/A)ratio as a prognostic indicator for patients with hepatitis cirrhosis undergoing splenectomy.METHODS A total of 257 patients diagnosed with hepatitis cirrhosis were retrospectively enrolled in the study.Normality test,t-test,Wilcoxon test,χ2 test,or Fisher’s exact test was employed to analyze the intraoperative and postoperative conditions of the patients.Receiver operating characteristic(ROC)curve analysis was utilized to depict the 10-year overall survival rate.RESULTS During the follow-up period,85.99%of the patients survived,with a median survival time of 64.6 months.Multivariate analysis revealed that total serum B/A ratio was an independent risk factor for overall survival(P=0.037).ROC curve analysis demonstrated that a B/A ratio of 0.87 was the optimal cut-off value.Consequently,the patients were categorized into two groups:High B/A group(n=64)and low B/A group(n=193).The median follow-up time for the high B/A group and low B/A group was 56.8 months and 67.2 months,respectively(P=0.045).Notably,the high B/A group exhibited a significantly lower 10-year overall survival compared to the low B/A group(P<0.001).Patients with hepatocellular carcinoma(HCC)had lower overall survival rates.Patients with a high B/A ratio exhibited a lower overall survival than those with a low B/A rate in the overall cohort and the subgroups of patients with HCC or not,early Child-Pugh grade,low albumin-bilirubin grade,and model for end-stage liver disease score≥10(log-rank test,P<0.001 for all).CONCLUSION The B/A ratio can serve as an effective prognostic indicator for overall survival in patients with hepatitis B virusrelated cirrhosis following splenectomy,and a higher B/A ratio may suggest a poorer prognosis.

Intraluminal migration of a surgical drain near an anastomosis site after total gastrectomy:A case report

BACKGROUND Esophagojejunal anastomotic leakage(EJAL)is a severe complication following gastrectomy for gastric cancer,typically treated with drainage and nutritional support.We report a case of intraluminal drain migration near the esophagojejunal anastomosis(EJA),resulting in persistent drainage and mimicking EJAL after total gastrectomy.CASE SUMMARY A 64-year-old male underwent open total gastrectomy with Roux-en-Y reconstruction for gastric adenocarcinoma,with two silicone drains placed near the EJA.On postoperative day(POD)4,the patient developed signs of peritonitis and sepsis,necessitating surgical re-exploration abscess drainage,peritoneal lavage,and drain repositioning.A contrast swallow study on POD 18 revealed rapid filling of the abdominal drain without extraluminal contrast collection.Persistent drainage prompted an upper gastrointestinal endoscopy on POD 59,which revealed approximately 5 cm of the drain within the esophagus,with the perforation site located 2 cm distal to the intact EJA.The drain was repositioned under endoscopic guidance.A repeat contrast radiograph on POD 67 demonstrated no evidence of extraluminal contrast extravasation or filling of the abdominal drain.The patient was subsequently discharged without further incident.CONCLUSION Intraluminal drain migration is a rare complication following gastric surgery but should be considered when persistent drainage occurs.

Integrating finite element analysis in total hip arthroplasty for childhood hip disorders:Enhancing precision and outcomes

Total hip arthroplasty for adults with sequelae from childhood hip disorders poses significant challenges due to altered anatomy.The paper published by Oommen et al reviews the essential management strategies for these complex cases.This article explores the integration of finite element analysis(FEA)to enhance surgical precision and outcomes.FEA provides detailed biomechanical insights,aiding in preoperative planning,implant design,and surgical technique optimization.By simulating implant configurations and assessing bone quality,FEA helps in customizing implants and evaluating surgical techniques like subtrochanteric shortening osteotomy.Advanced imaging techniques,such as 3D printing,virtual reality,and augmented reality,further enhance total hip arthroplasty precision.Future research should focus on validating FEA models,developing patient-specific simulations,and promoting multidisciplinary collaboration.Integrating FEA and advanced technologies in total hip arthroplasty can improve functional outcomes,reduce complications,and enhance quality of life for patients with childhood hip disorder sequelae.

Petersen's hernia with chylous ascites following laparoscopic total gastrectomy and Roux-en-Y anastomosis:A case report and review of literature

BACKGROUND Petersen’s hernia occurring through the epiploic foramen of the greater omentum,is an uncommon type of internal hernia.When it presents with complications such as chylous ascites,which is the lymphatic fluid accumulation in the abdominal cavity,it is particularly rare.Following laparoscopic total gastrectomy and Roux-en-Y anastomosis,the incidence of this condition is exceedingly low.CASE SUMMARY A 62-year-old male patient developed Petersen’s hernia following laparoscopic total gastrectomy(LTG)for gastric cancer,after Roux-en-Y anastomosis.Intestinal torsion and obstruction were experienced by the patient,along with a small amount of chylous ascites.Imaging studies and clinical assessment confirmed the diagnosis.Emergency surgery was performed promptly for the patient in the operating room.The twisted small intestine was reduced and the defect in Petersen’s space was repaired.The procedure was successful in the correction of the intestinal torsion and approximation of the hernia without the need for bowel resection.The patient’s condition significantly improved following the surgery.The ascites evolved from a milky white appearance to a pale yellow,with a substantial decrease in the triglyceride levels in the ascitic fluid,implying a favorable recovery trajectory.The patient was monitored closely and received appropriate care postoperatively,including nutritional support and fluid management.CONCLUSION This report illustrates the significance of recognizing Petersen’s hernia as a potential complication following gastrectomy for gastric cancer.It highlights the fundamental role of early surgical intervention in the effective management of such complications.The favorable outcome in this patient illustrates that prompt and appropriate surgical management can deter the necessity for more extensive procedures such as bowel resection.

Predictive value of C-reactive protein,procalcitonin,and total bilirubin levels for pancreatic fistula after gastrectomy for gastric cancer

BACKGROUND Gastric cancer is the most common malignancy of the digestive system and surgical resection is the primary treatment.Advances in surgical technology have reduced the risk of complications after radical gastrectomy;however,post-surgical pancreatic fistula remain a serious issue.These fistulas can lead to abdominal infections,anastomotic leakage,increased costs,and pain;thus,early diagnosis and prevention are crucial for a better prognosis.Currently,C-reactive protein(CRP),procalcitonin(PCT),and total bilirubin(TBil)levels are used to predict post-operative infections and anastomotic leakage.However,their predictive value for pancreatic fistula after radical gastrectomy for gastric cancer remains unclear.The present study was conducted to determine their predictive value.AIM To determine the predictive value of CRP,PCT,and TBil levels for pancreatic fistula after gastric cancer surgery.METHODS In total,158 patients who underwent radical gastrectomy for gastric cancer at our hospital between January 2019 and January 2023 were included.The patients were assigned to a pancreatic fistula group or a non-pancreatic fistula group.Multivariate logistic analysis was conducted to assess the factors influencing development of a fistula.Receiver operating characteristic(ROC)curves were used to determine the predictive value of serum CRP,PCT,and TBil levels on day 1 postsurgery.RESULTS On day 1 post-surgery,the CRP,PCT,and TBil levels were significantly higher in the pancreatic fistula group than in the non-pancreatic fistula group(P<0.05).A higher fistula grade was associated with higher levels of the indices.Univariate analysis revealed significant differences in the presence of diabetes,hyperlipidemia,pancreatic injury,splenectomy,and the biomarker levels(P<0.05).Logistic multivariate analysis identified diabetes,hyperlipidemia,pancreatic injury,CRP level,and PCT level as independent risk factors.ROC curves yielded predictive values for CRP,PCT,and TBil levels,with the PCT level having the highest area under the curve(AUC)of 0.80[95%confidence interval(CI):0.72-0.90].Combined indicators improved the predictive value,with an AUC of 0.86(95%CI:0.78-0.93).CONCLUSION Elevated CRP,PCT,and TBil levels predict risk of pancreatic fistula post-gastrectomy for gastric cancer.

Functional metabolomics analysis of the protective mechanism of total flavonoids of Scutellaria baicalensis on acute myocardial ischemia rats

Background:The study aimed to investigate the protective effect and mechanism of total flavonoids of Scutellaria baicalensis(TFSB)on acute myocardial ischemia(AMI)rats by using functional metabonomics.Methods:Rats were divided into the Control,Model,AMI positive control(Propranolol hydrochloride,30 mg/kg),low dose TFSB(50 mg/kg),and high dose TFSB(100 mg/kg)groups.Rats received the corresponding treatment by intragastric administration once daily for 10 consecutive days.Electrocardiogram,myocardial enzyme,triphenyltetrazolium chloride staining,hematoxylin-eosin,and enzyme-linked immunosorbent assay were performed to evaluate the protective effect of TFSB on AMI rats.Then,the UHPLC-Q-Orbitrap MS method based on serum metabolomics was utilised to search for metabolic biomarkers and metabolic pathways.Subsequently,Western blot and RT-PCR techniques were employed to identify the respective genes and proteins.Results:Pharmacodynamics revealed that TFSB could ameliorate AMI in rats.The results of the metabolomics analysis indicated that the alterations in metabolic profile observed in rats with AMI were partially improved by treatment with TFSB.Moreover,the mRNA expression levels of 5-lipoxygenase(5-LOX)and 15-lipoxygenase(15-LOX)and the protein expression levels of 5-LOX,15-LOX,interleukin-1β(IL-1β),and NF-κB p65 were reduced following treatment with TFSB.Conclusion:The potential treatment of TFSB in AMI may be ascribed to its ability to regulate arachidonic acid metabolism.

Assessment of the hip-spine relationship in total hip arthroplasty for childhood hip disorders sequelae

In this article,we comment on the article by Oommen et al.Oommen et al provided a comprehensive overview of the management of hip centre restoration in total hip arthroplasty(THA)for childhood hip disorder sequelae.Given the developmental disparity in this population,specific preoperative planning is an essential prerequisite for the success of THA procedures.In the review by Oommen et al,assessments of acetabular and femoral anatomic variations were fully described.However,spinal malalignment and stiffness are common in physical and radiological examinations and should be taken into careful consideration when planning surgical procedures.Poor outcomes of THA for patients with comorbid hip and spinopelvic pathologies have been widely reported,especially for hips with childhood disorder sequelae.Therefore,in this editorial,we would like to emphasize the need for a thorough hip-spine evaluation of patients with childhood hip disorder sequelae before THA.

Long-term follow-up result of short metaphyseal femoral stem in primary total hip arthroplasty:A retrospective study

BACKGROUND Total hip arthroplasty(THA)has increased along with an increasing demand for improved quality of life.Combined with prolonged life expectancy,the number of revision surgeries is expected to increase.Stress shielding is a significant issue with traditional femoral stems used in THA,making revision surgeries particularly challenging in younger patients.This has sparked renewed interest in studying safety and functional outcomes of short metaphyseal femoral stems,which have the potential to alleviate these challenges and simplify revision surgeries.AIM To evaluate the long-term outcomes of short-stem THA.METHODS A total of 124 hips that underwent THA using the short femoral stem(TRILOCK®Depuy)between May 2006 and November 2008 were included in this study.Patients were followed for a period of 15 years.Outcomes were assessed in terms of pain relief,hip joint range of motion,improvement in mobility,and functional outcomes using the modified Harris Hip Score,Oxford hip score,and Western Ontario and McMaster Universities Osteoarthritis index score.RESULTS A total of 124 hips in 98 patients were evaluated.Significant improvements in functional outcomes were observed over the 15-year follow-up period,with no cases of subsidence,implant loosening,or complications necessitating revision surgery.The only complication reported was heterotopic ossification in 1 patient.CONCLUSION Short metaphyseal stems provide better functional outcomes with early mobilization,and its long-term follow-up without subsidence,implant loosening,or proximal femoral bone loss simplifies revision surgery in younger patients.

Comparison of totally laparoscopic total gastrectomy using an endoscopic linear stapler with laparoscopic-assisted total gastrectomy using a circular stapler in patients with gastric cancer: a single-center experience

AIM To evaluate the safety and efficacy of totally laparoscopic total gastrectomy(TLTG) with esophagojejunostomy using a linear stapler compared with laparoscopic-assisted total gastrectomy(LATG) using a circular stapler in gastric cancer patients.METHODS We retrospectively reviewed 687 patients who underwent laparoscopic total gastrectomy for gastric cancer at a single institution from August 2008 to August 2014. The patients were divided into two groups according to the type of operation: 421 patients underwent TLTG and 266 underwent LATG. Clinicopathologic characteristics and surgical outcomes in the two groups were compared and analyzed.RESULTS The TLTG group had higher mean ages at the time of operation(57.78 ± 11.20 years and 55.69 ± 11.96 years,P = 0.020) and more histories of abdominal surgery(20.2% and 12.4%,P = 0.008) compared with the LATG group. Surgical outcomes such as intraoperative and postoperative transfusions,combined operations,pain scores and administration of analgesics,and complications were similar between the two groups. However,compared with the LATG group,the TLTG group required a shorter operation time(149 min vs 170 min,P < 0.001),had lower postoperative hematocrit change(3.49% vs 4.04%,P = 0.002),less intraoperative events(3.1% vs 10.2%,P < 0.001),less intraoperative anastomosis events(2.4% vs 7.1%,P = 0.003),faster postoperative recovery such as median time to first flatus(3.30 d vs 3.60 d,P < 0.001),faster median commencement of soft diet(4.30 d vs 4.60 d,P < 0.001) and shorter length of postoperative hospital stay(6.75 d vs 7.02 d,P = 0.005). CONCLUSION The intracorporeal method for reconstruction of esophagojejunostomy using a linear stapler may be considered a feasible procedure comparing with extracorporeal anastomosis using circular stapler because TLTG is simpler and more straightforward than LATG. Therefore,TLTG can be recommended as an appropriate procedure for gastric cancer.

Intracorporeal esophagojejunostomy after totally laparoscopic total gastrectomy: A single-center 7-year experience

AIM: To assess the efficacy and safety of intracorporeal esophagojejunostomy in patients undergoing laparoscopic total gastrectomy(LTG) for gastric cancer.METHODS: A retrospective review of 81 consecutive patients who underwent LTG with the same surgical team between November 2007 and July 2014 was performed. Four types of intracorporeal esophagojejunostomy using staplers or hand-sewn suturing were performed after LTG. Data on clinicopatholgoical characteristics, occurrence of complications, postoperative recovery, anastomotic time, and operation time among the surgical groups were obtained through medical records.RESULTS: The average operation time was 288.7 min, the average anastomotic time was 54.3 min, and the average estimated blood loss was 82.7 m L. There were no cases of conversion to open surgery. The first flatus was observed around 3.7 d, while the liquid diet was started, on average, from 4.9 d. The average postoperative hospital stay was 10.1 d. Postoperative complications occurred in 14 patients, nearly 17.3%.However, there were no cases of postoperative death.CONCLUSION: LTG performed with intracorporeal esophagojejunostomy using laparoscopic staplers or hand-sewn suturing is feasible and safe. The surgical results were acceptable from the perspective of minimal invasiveness.

Short-term outcomes of overlapped delta-shaped anastomosis, an innovative intracorporeal anastomosis technique, in totally laparoscopic colectomy for colon cancer

AIM To introduce an innovative intracorporeal anastomosis technique named overlapped delta-shaped anastomosis(ODA)for colon cancer cases undergoing totally laparoscopic colectomy(TLC)and to assess its feasibility and safety. METHODS From January 2016 to March 2017,a total of 20consecutive patients with colon cancer accepted TLC and the ODA technique at our medical center.Patient demographics,operative outcomes,perioperative complications,and pathological results were collected and analyzed. RESULTS We successfully completed TLC and the ODA procedure in all 20 cases,including 6(30%)males and 14(70%)females.In total,11(55%),2(10%),and 7(35%)cases accepted right hemicolectomy,transverse hemicolectomy,and left hemicolectomy,respectively.None of the surgeries were converted to an open operation.Mean operative time was 178.5 min,and mean estimated blood loss was 58.5 m L.Mean time to first flatus was 2.5 d,and mean postoperative hospitalization duration was 6.8 d.No severe complications occurred,such as anastomotic leakage,snastomotic stenosis,anastomotic bleeding,and wound infection,except for one case who suffered from an abdominal infection and another case who suffered from gastric paralysis syndrome.Tumor recurrence was not observed in any patient during the follow-up period. CONCLUSION The ODA technique for colon cancer cases undergoing TLC appears to be safe and feasible,although our current results need to be verified in further studies.

Digestive tract reconstruction using isoperistaltic jejunumlater-cut overlap method after totally laparoscopic total gastrectomy for gastric cancer: Short-term outcomes and impact on quality of life

AIM To evaluate the short-term outcomes and quality of life(Qo L) in gastric cancer patients undergoing digestive tract construction using the isoperistaltic jejunum-latercut overlap method(IJOM) after totally laparoscopic total gastrectomy(TLTG).METHODS A total of 507 patients who underwent laparoscopic gastrectomy(D2) from January 2014 to March 2016 were originally included in the study. The patients were divided into two groups to undergo digestive tract construction using either IJOM after TLTG(group T, n = 51) or Roux-en-Y anastomosis after laparoscopic-assisted total gastrectomy(LATG)(group A, n = 456). The short-term outcomes and Qo L were compared between the two groups after 1:2 propensity-score matching(PSM). We used a questionnaire to assess Qo L.RESULTS Before matching, age, sex, tumor size, tumor location, preoperative albumin and blood loss were significantly different between the two groups(P < 0.05). After PSM, the patients were well balanced in terms of their clinicopathological characteristics, although both blood loss and in-hospital postoperative days in group T were significantly lower than those in group A(P < 0.05). After matching, group T reported better Qo L in the domains of pain and dysphagia. Among the items evaluating pain and dysphagia, group T tended to report better Qo L("Have you felt pain" and "Have you had difficulty eating solid food")(P < 0.05).CONCLUSION The IJOM for digestive tract reconstruction after TLTG is associated with reduced blood loss and less pain and dysphagia, thus improving Qo L after laparoscopic gastrectomy.

Efficacy of totally laparoscopic compared with laparoscopic-assisted total gastrectomy for gastric cancer: A meta-analysis

BACKGROUND Laparoscopic radical gastrectomy is currently the most common surgical approach for gastric cancer.The main difference between totally laparoscopic total gastrectomy(TLTG)and laparoscopic-assisted total gastrectomy(LATG)is the route of digestive tract reconstruction.However,TLTG is currently not widespread as the safety and feasibility of intracorporeal esophagojejunostomy is uncertain.AIM To compare the short-term efficacy of TLTG and LATG for radical gastrectomy of gastric cancer,and to determine the safety and feasibility of intracorporeal esophagojejunostomy.METHODS PubMed,EMBASE,and Web of Science databases were searched for all relevant articles regarding TLTG vs LATG for gastric cancer published up to October 1,2019.Inclusion and exclusion criteria were established.All the basic conditions of patients and important clinical data related to surgery were extracted,and a meta-analysis was performed with RevMan 5.3 software.RESULTS Eight studies involving a total of 1883 cases(869 cases in the TLTG group and 1014 cases in the LATG group)were included.Compared with the LATG group,reduced intraoperative blood loss(weighted mean difference=-35.37,95%CI:-61.69--9.06,P=0.008)and a larger number of retrieved lymph nodes(weighted mean difference=3.11,95%CI:-2.60-12.00,P=0.01)were found in the TLTG group.There were no significant differences in operating time,anastomotic time,tumor size,proximal resection margin length,postoperative pain score,time to first flatus,time to first oral intake,postoperative hospital stay,postoperative anastomosis-related complication rate and overall complication rate between the two groups(P>0.05).CONCLUSION Intracorporeal esophagojejunostomy is safe and feasible.TLTG has the advantages of being minimally invasive,reduced intraoperative blood loss and easier access to lymph nodes compared with LATG.Totally laparoscopic gastrectomy is likely to be the surgical trend for gastric cancer in the future.

Shanghai expert consensus on totally implantable access ports 2019

Totally implantable access ports(TIAPs)are used for patients with poor peripheral vascular support requiring central venous access.In recent years,TIAPs have been gradually accepted and promoted by patients,doctors,and nurses owing to their advantages of convenient carrying,a long maintenance period,low complications,and a high quality of life for patients.Currently,medical personnel that handle TIAP implantation and management in China are from different areas of healthcare,including surgery,internal medicine,radiology,nurse anesthesia,vascular access,etc.,and many only handle TIAP as a part of their duties.Therefore,the operating procedures and steps for the diagnosis and treatment of complications of TIAP vary from person to person,resulting in different incidence and treatment methods for complications in the implantation and use of TIAP in different medical units.Based on this,we have updated the Shanghai expert consensus on TIAPs from 2015 and explored the diagnosis and treatment procedures of related complications while continuing to emphasize standardized implantation and maintenance.

Totally laparoscopic total gastrectomy using the modified overlap method and conventional open total gastrectomy:A comparative study

BACKGROUND Although several methods of totally laparoscopic total gastrectomy(TLTG)have been reported.The best anastomosis technique for LTG has not been established.AIM To investigate the effectiveness and surgical outcomes of TLTG using the modified overlap method compared with open total gastrectomy(OTG)using the circular stapled method.METHODS We performed 151 and 131 surgeries using TLTG with the modified overlap method and OTG for gastric cancer between March 2012 and December 2018.Surgical and oncological outcomes were compared between groups using propensity score matching.In addition,we analyzed the risk factors associated with postoperative complications.RESULTS Patients who underwent TLTG were discharged earlier than those who underwent OTG[TLTG(9.62±5.32)vs OTG(13.51±10.67),P<0.05].Time to first flatus and soft diet were significantly shorter in TLTG group.The pain scores at all postoperative periods and administration of opioids were significantly lower in the TLTG group than in the OTG group.No significant difference in early,late and esophagojejunostomy(EJ)-related complications or 5-year recurrence free and overall survival between groups.Multivariate analysis demonstrated that body mass index[odds ratio(OR),1.824;95%confidence interval(CI):1.029-3.234,P=0.040]and American Society of Anaesthesiologists(ASA)score(OR,3.154;95%CI:1.084-9.174,P=0.035)were independent risk factors of early complications.Additionally,age was associated with≥3 Clavien-Dindo classification and EJrelated complications.CONCLUSION Although TLTG with the modified overlap method showed similar complication rate and oncological outcome with OTG,it yields lower pain score,earlier bowel recovery,and discharge.Surgeons should perform total gastrectomy cautiously and delicately in patients with obesity,high ASA scores,and older ages.
