Clinical study on the effect of jejunoileal side-to-side anastomosis on metabolic parameters in patients with type 2 diabetes

BACKGROUND At present,the existing internal medicine drug treatment can alleviate the high glucose toxicity of patients to a certain extent,to explore the efficacy of laparoscopic jejunoileal side to side anastomosis in the treatment of type 2 diabetes,the report is as follows.AIM To investigate the effect of jejunoileal side-to-side anastomosis on metabolic parameters in patients with type 2 diabetes mellitus(T2DM).METHODS We retrospectively analyzed the clinical data of 78 patients with T2DM who were treated via jejunoileal lateral anastomosis.Metabolic indicators were collected preoperatively,as well as at 3 and 6 months postoperative.The metabolic indicators analyzed included body mass index(BMI),systolic blood pressure(SBP),diastolic blood pressure(DBP),fasting blood glucose(FBG),2-hour blood glucose(PBG),glycated hemoglobin(HbA1c),fasting C-peptide,2-hour C-peptide(PCP),fasting insulin(Fins),2-hour insulin(Pins),insulin resistance index(HOMA-IR),βCellular function index(HOMA-β),alanine aminotransferase,aspartate aminotransferase,serum total cholesterol(TC),low-density lipoprotein cholesterol(L DL-C),triglycerides(TG),high-density lipoprotein,and uric acid(UA)levels.RESULTS SBP,DBP,PBG,HbA1c,LDL-C,and TG were all significantly lower 3 months postoperative vs preoperative values;body weight,BMI,SBP,DBP,FBG,PBG,HbA1c,TC,TG,UA,and HOMA-IR values were all significantly lower 6 months postoperative vs at 3 months;and PCP,Fins,Pins,and HOMA-βwere all significantly higher 6 months postoperative vs at 3 months(all P<0.05).CONCLUSION Side-to-side anastomosis of the jejunum and ileum can effectively treat T2DM and improve the metabolic index levels associated with it.

Comparative study of cylindrical vs circular ring magnets for colonic anastomosis in rats

BACKGROUND Magnetic compression anastomosis(MCA)offers a simple and reliable technique for inducing anastomoses at any point along the digestive tract.Evidence regarding whether the design of the MCA device influences the anastomosis effect is lacking.AIM To investigate any difference in the side-to-side colonic anastomosis effect achieved with cylindrical vs circular ring magnets.METHODS We designed cylindrical and circular ring magnets suitable for side-to-side colonic anastomosis in rats.Thirty Sprague-Dawley rats were randomly divided into a cylindrical group,circular ring group,and cylindrical–circular ring group(n=10/group).Side-to-side colonic anastomosis was completed by transanal insertion of the magnets without incision of the colon.Operation time,perioperative complications,and magnet discharge time were recorded.Rats were euthanized 4 weeks postoperatively,and anastomotic specimens were obtained.The burst pressure and anastomotic diameter were measured sequentially,and anastomosis formation was observed by naked eye.Histological results were observed by light microscopy.RESULTS In all 30 rats,side-to-side colonic anastomosis was completed,for an operation success rate of 100%.No postoperative complications of bleeding and intestinal obstruction occurred,and the postoperative survival rate were 100%.The operation time,magnet discharge time,anastomotic bursting pressure,and anastomotic diameter did not differ significantly among the three designs(P>0.05).Healing was similar across the groups,with gross specimens showing good anastomotic healing and good mucosal continuity observed on histological analysis.CONCLUSION This study found no significant difference in the establishment of rat side-to-side colonic anastomosis with the use of cylindrical vs circular ring magnets.

Comparative study of clinical efficacy of laparoscopic proximal gastrectomy with double-channel anastomosis and tubular gastroesophageal anastomosis

BACKGROUND According to statistics,the incidence of proximal gastric cancer has gradually increased in recent years,posing a serious threat to human health.Tubular gastroesophageal anastomosis and double-channel anastomosis are two relatively mature anti-reflux procedures.A comparison of these two surgical procedures,tubular gastroesophageal anastomosis and double-channel anastomosis,has rarely been reported.Therefore,this study aimed to investigate the effects of these two reconstruction methods on the quality of life of patients with proximal gastric cancer after proximal gastrectomy.AIM To compare short-term clinical results of laparoscopic proximal gastrectomy with double-channel anastomosis vs tubular gastric anastomosis.METHODS Patients who underwent proximal gastrectomy at our hospital between January 2020 and January 2023 were enrolled in this retrospective cohort study.The patients were divided into an experimental group(double-channel anastomosis,33 cases)and a control group(tubular gastric anastomosis,30 cases).Baseline characteristics,surgical data,postoperative morbidities,and postoperative nutrition were recorded.RESULTS The differences in baseline data,surgical data,and postoperative complications(20.0%vs 21.2%)were not statistically significant between the two groups.There were no statistically significant differences in the levels of postoperative nutrition indicators between the two groups of patients during the preoperative period and at 3 months postoperatively.In addition,the levels of postoperative nutrition indicators in patients in the experimental group declined significantly less at 6 months and 12 months postoperatively compared with those of the control group(P<0.05).At 12 months postoperatively,the difference in anastomotic reflux esophagitis between the two groups was statistically significant(P<0.05)with the experimental group showing less reflux esophagitis.CONCLUSION Both double-channel anastomosis and tubular gastric anastomosis after proximal gastrectomy are safe and feasible.Double-channel anastomosis has a better anti-reflux effect and is more beneficial in improving the postoperative nutritional status.

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.

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.

Laparoscopic intracorporeal anastomosis vs open anastomosis for ileostomy reversal in Crohn's disease:A single center retrospective study

BACKGROUND There is an increased maturation of laparoscopic intracorporeal anastomosis techniques.However,research on its application for small bowel stoma reversal in patients with Crohn's disease(CD)is limited.Therefore,in this study,we compared the perioperative outcomes between laparoscopic intracorporeal ileostomy reversal(LIIR)and open ileostomy reversal(OIR).AIM To compare the safety,feasibility,bowel function recovery,and short-and longterm LIIR and OIR outcomes in patients with CD.METHODS This study included patients who underwent ileal reversal for CD between January 2021 and January 2023 at our institution.The baseline data,postoperative recovery,and complication indicators were retrospectively analyzed.Logistic regression analysis was conducted to explore factors that significantly influenced the development of enteral nutrition intolerance-related symptoms.RESULTS Notably,15 of the 45 patients in this study underwent OIR,and the remaining 30 received LIIR.Notably,no statistically significant differences were found between the two groups regarding clinical baseline characteristics,operation time,intraoperative hemorrhage,anastomotic site,enterolysis range,first postoperative flatus,postoperative complications,reoperation rate,or incidence of postoperative enteral nutrition intolerance.Compared with the OIR group,the LIIR group had a shorter postoperative hospital stay(P=0.045),lower incidence of enteral nutrition intolerance symptoms(P=0.019),and earlier postoperative total enteral nutrition initiation(P=0.033);however,it incurred higher total hospital costs(P=0.038).Furthermore,multivariate logistic regression analysis revealed that the duration of surgery and anastomotic technique were independent risk factors for postoperative symptoms of enteral nutrition intolerance(P<0.05).CONCLUSION Laparoscopic intracorporeal anastomosis for ileostomy reversal is safe and feasible.Patients who underwent this technique demonstrated improved tolerance to postoperative enteral nutrition and quicker resumption of total enteral nutrition.

Evaluation of bacterial contamination and medium-term oncological outcomes of intracorporeal anastomosis for colon cancer:A propensity score matching analysis

BACKGROUND Although intracorporeal anastomosis(IA)for colon cancer requires longer operative time than extracorporeal anastomosis(EA),its short-term postoperative results,such as early recovery of bowel movement,have been reported to be equal or better.As IA requires opening the intestinal tract in the abdominal cavity under pneumoperitoneum,there are concerns about intraperitoneal bacterial infection and recurrence of peritoneal dissemination due to the spread of bacteria and tumor cells.However,intraperitoneal bacterial contamination and medium-term oncological outcomes have not been clarified.abdominal cavity in IA.METHODS Of 127 patients who underwent laparoscopic colon resection for colon cancer from April 2015 to December 2020,75 underwent EA(EA group),and 52 underwent IA(IA group).After propensity score matching,the primary endpoint was 3-year disease-free survival rates,and secondary endpoints were 3-year overall survival rates,type of recurrence,surgical site infection(SSI)incidence,number of days on antibiotics,and postoperative biological responses.RESULTS Three-year disease-free survival rates did not significantly differ between the IA and EA groups(87.2%and 82.7%,respectively,P=0.4473).The 3-year overall survival rates also did not significantly differ between the IA and EA groups(94.7%and 94.7%,respectively;P=0.9891).There was no difference in the type of recurrence between the two groups.In addition,there were no significant differences in SSI incidence or the number of days on antibiotics;however,postoperative biological responses,such as the white blood cell count(10200 vs 8650/mm^(3),P=0.0068),C-reactive protein(6.8 vs 4.5 mg/dL,P=0.0011),and body temperature(37.7 vs 37.5℃,P=0.0079),were significantly higher in the IA group.CONCLUSION IA is an anastomotic technique that should be widely performed because its risk of intraperitoneal bacterial contamination and medium-term oncological outcomes are comparable to those of EA.

Benign stricture of bilioenteric anastomosis after Whipple withsynthetic polypropylene suture

To the Editor:Biliary stricture formation at the bilioenteric anastomosis is an infrequent complication(2%-3%)after pancreaticoduodenectomy;the average presentation is within 13-14 months(range from 1 month to 9 years)after surgery[1,2].While the etiology is unknown,development of biliary stricture has shown to be more likely if a bile leak occurs in the postoperative period[3,4]and with younger patients[5].

T-tube bridging fistula jejunal anastomosis for treatment of pancreatic lumbar dorsal fistula after necrotizing pancreatitis

Infectious pancreatic necrosis causes external pancreatic fistula in some patients.Generally,external pancreatic fistula requires fistula-gastric and/or intestinal anastomosis,and digestive endoscopic interventional treatment[1–3].It is especially difficult to treat external pancreatic fistulas with small fistulas where the external fistula is located in the lower back.The common treatment is to remove the body and tail of the pancreas and the spleen.This operation is very traumatic.A new pancreatic fistula may still occur at the pancreatic stump.The above operations may lead to unnecessary resection of the spleen,colon injury and other complications.In order to solve this problem,we innovatively used T-tube bridging fistula jejunal anastomosis plus continuous negative pressure suction to treat three cases of external pancreatic fistulas in the lower back,and all of them achieved good results.

Influence of different magnetic forces on the effect of colonic anastomosis in rats

BACKGROUND Despite much work having been conducted on magnetic compression anastomo-sis(MCA)in the digestive tract,there are no reports on the influence of magnetic force on the anastomosis.AIM To investigate the effect of different magnetic force magnets on the MCA of the digestive tract.METHODS Two groups of magnets of the same sizes but different magnetic forces were designed and produced.A total of 24 Sprague-Dawley rats were randomly assigned into two groups(powerful magnet group and common magnet group),with 12 rats in each group.Two types of magnets were used to complete the colonic side-to-side anastomosis of the rats.The operation time and magnet discharge time were recorded.The anastomotic specimens were obtained 4 wk after the operation and then the burst pressure and diameter of the anastomosis were measured,and the anastomosis was observed via the naked eye and subjected to histological examination.RESULTS The magnetic forces of the powerful and common magnet groups at zero distance were 8.26 N and 4.10 N,respectively.The colonic side-to-side anastomosis was completed in all 24 rats,and the operation success rate and postoperative survival rate were 100%.No significant difference was noted in the operation time between the two groups.The magnet discharge time of the powerful magnet group was slightly longer than that of the common magnet group,but the difference was not statistically significant(P=0.513).Furthermore,there was no statistical difference in the burst pressure(P=0.266)or diameter of magnetic anastomosis(P=0.095)between the two groups.The gross specimens of the two groups showed good anastomotic healing,and histological observation indicated good mucosal continuity without differences on healing.CONCLUSION In the rat colonic side-to-side MCA model,both the powerful magnet with 8.26 N and the common magnet with 4.10 N showed no significant impact on the anastomosis establishment process or its effect.

Establishment of a chronic biliary disease mouse model with cholecystoduodenal anastomosis for intestinal microbiome preservation

BACKGROUND Chronic biliary disease,including cholangitis and cholecystitis,is attributed to ascending infection by intestinal bacteria.Development of a mouse model for bile duct inflammation is imperative for the advancement of novel therapeutic approaches.Current models fail to replicate the harmful bacterial influx to the biliary tract observed in humans and spread of inflammation to the liver.Therefore,we aimed to establish an animal model of biliary disease that faithfully replicates the mechanisms of human diseases.AIM To establish a cholecystoduodenal anastomosis model capable of mimicking the mechanisms of ascending infection and inflammation observed in human biliary diseases.METHODS We established a mouse biliary disease model by directly connecting the gallbladder and duodenum,enabling ascending infection into the biliary tract without traversing the sphincter of Oddi.RESULTS In the cholecystoduodenal anastomosis mouse model,we observed impaired epithelial structure,wall thickening,and macrophage recruitment in the gallbladder.Despite the absence of postoperative antibiotics,we detected no changes in serum proinflammatory cytokine levels,indicating no systemic inflammation.Moreover,patency between the gallbladder and duodenum was confirmed via common bile duct ligation.Injection of patient-derived pathogenic bacteria into bile duct-ligated mice led to ascending infection,which significantly increased proinflammatory cytokine mRNA expression in the liver,duodenum,and ileum.These results indicate that our mouse model exhibited a direct connection between the gallbladder and duodenum,leading to ascending infection and closely mimicking the clinical features of biliary diseases observed in humans.CONCLUSION The cholecystoduodenal anastomosis mouse model is an effective chronic biliary disease model with significant relevance in the development of microbiome-based therapies for the prevention and treatment of biliary disease.

New anti-mesenteric delta-shaped stapled anastomosis: Technical report with short-term postoperative outcomes in patients with Crohn’s disease

BACKGROUND Medical treatment for Crohn’s disease(CD)has continuously improved,which has led to a decrease in surgical recurrence rates.Despite these advancements,25%of patients will undergo repeat intestinal surgery.Recurrence of CD com-monly occurs on the mesentery side of the anastomosis site.AIM To compare the new anti-mesenteric side-to-side delta-shaped stapled anasto-mosis(DSA)with the conventional stapled functional end-to-end anastomosis(CSA).METHODS This retrospective study included CD patients who underwent ileo-ileal or ileo-colic anastomosis between January 2020 and December 2023.The DSA technique employed a stapler to maintain the concept of anti-mesentery side-to-side ana-stomosis by performing a 90°vertical closure of the open window compared with the CSA technique.At the corner where the open window is closed,the DSA avoids forming a pouch and creates an anastomosis resembling a delta shape within the intestinal lumen.We compared demographics,preoperative condition,operative findings,and operative outcomes for the two techniques.RESULTS The study included 175 patients,including 92 in the DSA group and 83 in the CSA group.The two groups were similar in baseline characteristics,preoperative medical treatment,and operative findings except for the Montreal classification location.The 30-days postoperative complication rate was signi-ficantly lower in the DSA group compared with the CSA group(16.3%vs 32.5%,P=0.009).Ileus incidence was significantly lower in the DSA group than in the CSA group(4.3%vs 14.5%,P=0.033),and the hospital stay was shorter in the DSA group than in the CSA group(5.67±1.53 days vs 7.39±3.68 days,P=0.001).CONCLUSION The DSA technique was feasible and showed comparable postoperative outcomes with lower short-term complic-ations compared with the CSA technique.Further studies on CD recurrence and long-term complications are warranted.

Clinical efficacy of modified Kamikawa anastomosis in patients with laparoscopic proximal gastrectomy

BACKGROUND With the increasing incidence of proximal gastric cancer,laparoscopic proximal gastrectomy has been applied.However,reflux esophagitis often occurs after traditional esophagogastric anastomosis.In order to solve this problem,several methods of digestive tract reconstruction have emerged,but the most satisfying method remains to be discussed.Therefore,we modified traditional Kamikawa anastomosis to investigate the appropriate digestive tract reconstruction in laparo-scopic proximal gastrectomy.All the patients were successfully operated on without conversion to laparotomy.The duration of operation and digestive tract reconstruction were 203.500(150-224)min and 87.500(73-111)min,respectively.The intraoperative amount of bleeding was 20.500 mL±0.696 mL.The time of postoperative first flatus,the first postoperative fluid intake,and the postoperative length of stay were 2(1-3)d,4(3-5)d,and 9(8-10)d,respectively.All the patients were followed up for 12-23 months.The body mass index at 6 and 12 months after surgery were 22.577 kg/m2±3.098 kg/m2 and 22.594 kg/m2±3.207 kg/m2,respectively.The nutrition risk screening 2002 score,the patient-generated subjective global assessment score,and the gastroesophageal reflux disease scale score were good at 6 and 12 months after surgery.Reflux esophagitis and anastomotic stenosis were not observed in any of the patients during their 12-month postoperative gastroscopy or upper gastrointestinal tract visits.All the patients exhibited no tumor recurrence or metastasis.CONCLUSION The modified Kamikawa anastomosis is safe and feasible for laparoscopic proximal gastrectomy and has good antireflux effects and nutritional status.

Primary repair of esophageal atresia Gross type C via thoracoscopic magnetic compression anastomosis:Is it the best option?

Magnetic compression anastomosis is a promising treatment option for patients with complex esophageal atresia;but,at the present time,should not be the first therapeutic option in those cases where the surgeon can perform a primary anastomosis of the two ends of the esophagus with acceptable tension.

Effect of growth hormone on colonic anastomosis after intraperitoneal administration of 5-fluorouracil, bleomycin and cisplatin: An experimental study

BACKGROUND Growth hormone(GH)plays a crucial role in wound healing and tissue repair in postoperative patients.In particular,colonic anastomosis healing following colorectal surgery is impaired by numerous chemotherapy agents.AIM To investigate whether GH can improve the healing of a colonic anastomosis following the adverse effects of intraperitoneal administration of 5-fluorouracil(5-FU),bleomycin and cisplatin.METHODS Eighty Wistar rats underwent laparotomy and a 1 cm-resection of the transverse colon,followed by an end-to-end anastomosis under general anesthesia.The rats were blindly allocated into four equal groups and administered a different daily intraperitoneal therapeutic regimen for 6 days.The control group(A)received normal saline.Group B received chemotherapy with 5-FU(20 mg/kg),bleomycin(4 mg/kg)and cisplatin(0.7 mg/kg).Group C received GH(2 mg/kg),and group D received the aforementioned combination chemotherapy and GH,as described.The rats were sacrificed on the 7th postoperative day and the anastomoses were macroscopically and microscop-ically examined.Body weight,bursting pressure,hydroxyproline levels and inflammation markers were measured.RESULTS All rats survived until the day of sacrifice,with no infections or other complications.A decrease in the body weight of group D rats was observed,not statistically significant compared to group A(P=1),but significantly different to groups C(P=0.001)and B(P<0.01).Anastomotic dehiscence rate was not statistically different between the groups.Bursting pressure was not significantly different between groups A and D(P=1.0),whereas group B had a significantly lower bursting pressure compared to group D(P<0.001).All groups had significantly more adhesions than group A.Hydroxyproline,as a measurement of collagen deposition,was significantly higher in group D compared to group B(P<0.05),and higher,but not statistically significant,compared to group A.Significant changes in group D were recorded,compared to group A regarding inflammation(3.450 vs 2.900,P=0.016)and fibroblast activity(2.75 vs 3.25,P=0.021).Neoangiogenesis and collagen deposition were not signifi-cantly different between groups A and D.Collagen deposition was significantly increased in group D compared to group B(P<0.001).CONCLUSION Intraperitoneal administration of chemotherapy has an adverse effect on the healing process of colonic anastomosis.However,GH can inhibit the deleterious effect of administered chemotherapy agents and induce colonic healing in rats.

Impact of different anastomosis methods on post-recurrence after intestinal resection for Crohn's disease:A meta-analysis

BACKGROUND Crohn's disease(CD)is a chronic inflammatory disease of the gastrointestinal tract,often requiring intestinal resection as a common treatment.However,recurrence after surgery is common.The anastomotic configuration after bowel resection appears to be associated with the recurrence of CD.Previous studies have suggested that the Kono-S anastomosis may help to reduce the recurrence rate.However,the results remain controversial.Therefore,evidence-based evidence is needed to prove the advantages of Kono-S anastomosis.AIM To measure the influence of anastomosis techniques on the long-term relapse rate of CD by conducting a meta-analysis.METHODS PubMed,Scopus,and Cochrane Library were searched until October 8,2023.Patients who underwent intestinal resection due to CD were included.The intervention measures included Kono-S anastomosis,whereas the control group received traditional anastomosis such as end-to-end,end-to-side,and side-to-side anastomosis.Only randomized clinical trials and observational studies were included.The primary outcome measures were hospital stay post-surgery,overall postoperative complication incidence,the proportion of Clavien-Dindo grade IIIa or higher,overall postoperative recurrence rate,and Rutgeerts score.RESULTS From 2011 to 2023,six articles met the inclusion and exclusion criteria.The results indicated that Kono-S anastomosis can reduce the hospital stay post-surgery of patients with CD[MD=-0.26,95%CI:-0.42 to-0.10,P=0.002]than other traditional anastomosis methods.Compared to other traditional anastomosis methods,Kono-S anastomosis can significantly reduce the total recurrence rate[MD=0.40,95%CI:0.17 to 0.98,P=0.05]and postoperative Rutgeerts score[MD=-0.81,95%CI:-0.96 to-0.66,P<0.001]in patients with CD.However,there is no significant disparity in the overall occurrence of postoperative complications and the proportion of Clavien-Dindo≥IIIa.CONCLUSION Kono-S anastomosis has the potential to expedite the recuperation of CD and diminish relapse hazards;however,additional larger trials are necessary to authenticate its effectiveness.

Magnetic compression anastomosis to restore biliary tract continuity after obstruction following major abdominal trauma:A case report

BACKGROUND The combination of magnetic compression anastomosis(MCA)and endoscopy has been used to treat biliary stricture after liver transplantation.However,its use for the treatment of complex biliary obstruction after major abdominal trauma has not been reported.This case report describes the successful use of MCA for the treatment of biliary obstruction resulting from major abdominal trauma.A 23-year-old man underwent major abdominal surgery(repair of liver rupture,right half colon resection,and ileostomy)following a car accident one year ago.The abdominal drainage tube,positioned at the Winslow foramen,was draining approximately 600-800 mL of bile per day.During the two endoscopic retrograde cholangiopancreatography procedures,the guide wire was unable to enter the common bile duct,which prevented placement of a biliary stent.MCA combined with endoscopy was used to successfully achieve magnetic anastomosis of the peritoneal sinus tract and duodenum,and then a choledochoduodenal stent was placed.Finally,the external biliary drainage tube was removed.The patient achieved internal biliary drainage leading to the removal of the external biliary drainage tube,which improved the quality of life.CONCLUSION Magnetic compression technique can be used for the treatment of complex biliary obstruction with minimal operative trauma.

Evaluating bacterial contamination and surgical site infection risks in intracorporeal anastomosis: Role of bowel preparation

We recently read the study by Kayano et al on intracorporeal anastomosis(IA)for colon cancer,which assessed bacterial contamination and medium-term onco-logical outcomes and affirmed that IA is analogous to extracorporeal anastomosis in reducing intraperitoneal bacterial risk and achieving similar oncological results.Our commentary addresses gaps,particularly concerning bowel preparation and surgical site infections(SSIs),and highlights the need for comprehensive details on the bowel preparation methods that are currently employed,including mecha-nical bowel preparation,oral antibiotics(OA),their combination,and specific OA types.We emphasize the necessity for further analyses that investigate these me-thods and their correlation with SSI rates,to enhance clinical protocol guidance and optimize surgical outcomes.Such meticulous analyses are essential for refi-ning strategies to effectively mitigate SSI risk in colorectal surgeries.

Lymphovenous anastomosis and complex decongestive therapy for severe deformed lymphedema with recurrent infection:A case report

BACKGROUND Lower extremity lymphedema is a common complication following treatment for gynecological malignancies.Its incidence rate can reach up to 70%,affecting~20 million people worldwide.However,specialized treatment centers are scarce,and there is a lack of consensus on treatment approaches.Furthermore,there are even fewer reports on the systematic and effective treatment of severe lymphedema with malformations.Effective management of this condition remains a significant challenge for clinicians.CASE SUMMARY A 40-year-old woman developed bilateral leg swelling 6 years after receiving treatment for endometrial cancer.Since August 2018,she experienced>30 episodes of lymphangitis.Upon presentation,she exhibited bilateral leg swelling and deformation,with four large swellings in the posterior thigh that impeded movement,and pain in the limbs.Skin manifestations included lichenoid lesions and features of deep sclerosis.Radionuclide lymphoscintigraphy confirmed the diagnosis of lower limb lymphedema.After 6 mo of complex decongestive therapy(CDT)and three lymphaticovenous anastomosis(LVA)treatments,the patient lost 49 kg in weight.She also experienced a maximum circumference reduction of 35.2 cm in the left lower limb and 37.5 cm in the right lower limb.The leg pain disappeared,her swelling significantly decreased,and she regained the ability to walk,cycle,and run normally.CONCLUSION The combined application of CDT and LVA therapy demonstrates significant positive effects in the treatment of severe,deformed stage III lymphedema.

Radical Prostatectomy by Laparotomy: Retrospective Study Comparing Separate and Continuous Stitches in the Performance of Vesicourethral Anastomosis at a Single Center in the Public Health Network

Background: Prostate cancer ranks as the second most prevalent malignancy in men, with treatment strategies ranging from observation to various interventions. Radical prostatectomy is a common approach, aiming for a cure, and the technique for vesico-urethral anastomosis varies, employing separate or continuous stitches. However, a consensus on the optimal technique is lacking. This study aims to compare vesico-urethral anastomosis techniques (separate vs. continuous stitches) in laparotomy-based radical prostatectomies, evaluating peri and postoperative outcomes. Materials and Method: A retrospective analysis of 140 patients’ medical records yielded 86 eligible cases, divided into two groups based on anastomosis technique. Both groups underwent surgery at the same urology center between 2016 and 2019, with a follow-up period exceeding 12 months. Pre-operative characteristics were statistically similar between groups. Results: Perioperative complication rates did not significantly differ between the two techniques (p > 0.99). However, the continuous stitch group experienced a 20-minute longer procedure time (p 0.05), patients with continuous stitches had 2.5 times higher diaper usage at twelve months (p Conclusion: This research suggests that vesico-urethral anastomosis with separate stitches yields superior results in laparotomy-based radical prostatectomies compared to continuous stitches, demonstrating benefits in surgical time, hospital stay, sentinel drain duration, stenosis rates, and long-term urinary incontinence outcomes.
