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.

Modified Blumgart anastomosis without pancreatic duct-to-jejunum mucosa anastomosis for pancreatoduodenectomy：a feasible and safe novel technique

Objective：This study proposed a modified Blumgart anastomosis（m-BA）that uses a firm ligation of the main pancreatic duct with a supporting tube to replace the pancreatic duct-to-jejunum mucosa anastomosis,with the aim of simplifying the complicated steps of the conventional BA（c-BA）.Thus,we observe if a difference in the risk of postoperative pancreatic fistula（POPF）exists between the two methods.Methods：The m-BA anastomosis method has been used since 2010.From October 2011 to October 2015,147 patients who underwent pancreatoduodenectomy（PD）using BA in Tianjin Medical University Cancer Institute and Hospital were enrolled in this study.According to the type of pancreatojejunostomy（PJ）,50 patients underwent m-BA and 97 received c-BA.The two patient cohorts were compared prospectively to some extent but not randomized,and the evaluated variables were operation time,the incidence rate of POPF,and other perioperative complications.Results：The operation time showed no significant difference（P〉0.05）between the two groups,but the time of duct-to-mucosa anastomosis in the m-BA group was much shorter than that in the c-BA group（P〈0.001）.The incidence rate of clinically relevant POPF was 12.0%（6/50）in the modified group and 10.3%（10/97）in the conventional group（P〉0.05）,which means that the modified anastomosis method did not cause additional pancreatic leakage.The mean length of postoperative hospital stay of the m-BA group was 23 days,and that of the c-BA group was 22 days（P〉0.05）.Conclusions：Compared with the conventional BA,we suggest that the modified BA is a feasible,safe,and effective operation method for P J of PD with no sacrifice of surgical quality.In the multivariate analysis,we also found that body mass index（≥25

Endoscopic retrograde cholangiopancretography in modified double tracks anastomosis with anastomotic stenosis

A 63-year-old man presented at our hospital with right upper abdomen pain and fever for 4 d.The patient's magnetic resonance cholangiopancreatography revealed dilated common bile duct and choledocholithiasis.In his past history,he received proximal gastrectomy and modified double tracks anastomosis.Endoscopic retrograde cholangiopancretography in modified double tracks anastomosis,especially accompanied with anastomotic stenosis,has been rarely reported.In the present case,the duodenoscope was successfully introduced over the guidewire and the stone taken out using a basket.The patient had good palliation of his symptoms after removal of the stone.

Passive-bending,short-type single-balloon enteroscope for endoscopic retrograde cholangiopancreatography in Roux-en-Y anastomosis patients

AIM:To evaluate short-type-single-balloon enteroscope(SBE) with passive-bending,high-force transmission functions for endoscopic retrograde cholangiopancreatography(ERCP) in patients with Roux-en-Y anastomosis.METHODS:Short-type SBE with this technology(SIF-Y0004-V01; working length,1520 mm; channel diameter,3.2 mm) was used to perform 50 ERCP procedures in 37 patients with Roux-en-Y anastomosis.The rate of reaching the blind end,time required to reach the blind end,diagnostic and therapeutic success rates,and procedure time and complications were studied retrospectively and compared with the results of 34 sessions of ERCP performed using a short-type SBE without this technology(SIF-Y0004; working length,1520 mm; channel diameter,3.2 mm) in 25 patients.RESULTS:The rate of reaching the blind end was 90% with SIF-Y0004-V01 and 91% with SIF-Y0004(P = 0.59).The median time required to reach the papilla was significantly shorter with SIF-Y0004-V01 than with SIF-Y0004(16 min vs 24 min,P = 0.04).The diagnostic success rate was 93% with SIFY0004-V01 and 84% with SIF-Y0004(P = 0.17).The therapeutic success rate was 95% with SIF-Y0004-V01 and 96% with SIF-Y0004(P = 0.68).The median procedure time was 40 min with SIF-Y0004-V01 and 36 min with SIF-Y0004(P = 0.50).The incidence of hyperamylasemia was 6.0% in the SIF-Y0004-V01 group and 14.7% in the SIF-Y0004 group(P = 0.723).The incidence of pancreatitis was 0% in the SIFY0004-V01 group and 5.9% in the SIF-Y0004 group(P > 0.999).The incidence of gastrointestinal perforation was 2.0%(1/50) in the SIF-Y0004-V01 group and 2.9%(1/34) in the SIF-Y0004 group(P > 0.999).CONCLUSION:SIF-Y0004-V01 is useful for ERCP inpatients with Roux-en-Y anastomosis and may reduce the time required to reach the blind end.

Comparison between laparoscopic uncut Roux-en-Y and Billroth Ⅱ with Braun anastomosis after distal gastrectomy:A meta-analysis

BACKGROUND Conventional Billroth Ⅱ(BⅡ) anastomosis after laparoscopic distal gastrectomy(LDG) for gastric cancer(GC) is associated with bile reflux gastritis, and Roux-enY anastomosis is associated with Roux-Y stasis syndrome(RSS). The uncut Rouxen-Y(URY) gastrojejunostomy reduces these complications by blocking the entry of bile and pancreatic juice into the residual stomach and preserving the impulse originating from the duodenum, while BⅡ with Braun(BB) anastomosis reduces the postoperative biliary reflux without RSS. Therefore, the purpose of this study was to compare the efficacy and safety of laparoscopic URY with BB anastomosis in patients with GC who underwent radical distal gastrectomy.AIM To evaluate the value of URY in patients with GC.METHODS PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, Chinese Biomedical Database, and VIP Database for Chinese Technical Periodicals(VIP) were used to search relevant studies published from January 1994 to August 18, 2021. The following databases were also used in our search: Clinicaltrials.gov, Data Archiving and Networked Services, the World Health Organization International Clinical Trials Registry Platform Search Portal(https://www.who.int/clinical-trials-registry-platform/the-ictrp-search-portal), the reference lists of articles and relevant conference proceedings in August 2021. In addition, we conducted a relevant search by Reference Citation Analysis(RCA)(https://www.referencecitationanalysis.com). We cited highquality references using its results analysis functionality. The methodological quality of the eligible randomized clinical trials(RCTs) was evaluated using the Cochrane Risk of Bias Tool, and the non-RCTs were evaluated using the Newcastle-Ottawa scale. Statistical analyses were performed using Review Manager(Version 5.4).RESULTS Eight studies involving 704 patients were included in this meta-analysis. The incidence of reflux gastritis [odds ratio = 0.07, 95% confidence interval(CI): 0.03-0.19, P < 0.00001] was significantly lower in the URY group than in the BB group. The pH of the postoperative gastric fluid was lower in the URY group than in the BB group at 1 d [mean difference(MD) =-2.03, 95%CI:(-2.73)-(-1.32),P < 0.00001] and 3 d [MD =-2.03, 95%CI:(-2.57)-(-2.03), P < 0.00001] after the operation. However,no significant difference in all the intraoperative outcomes was found between the two groups.CONCLUSION This work suggests that URY is superior to BB in gastrointestinal reconstruction after LDG when considering postoperative outcomes.

Application of single balloon enteroscopy-assisted therapeutic endoscopic retrograde cholangiopancreatography in patients after bilioenteric Roux-en-Y anastomosis: Experience of multi-disciplinary collaboration

BACKGROUND Bilioenteric Roux-en-Y anastomosis is one of the most complicated approaches for reconstructing the gastrointestinal tract, and endoscopic retrograde cholangiopancreatography (ERCP) is technically challenging in patients after bilioenteric Roux-en-Y anastomosis. The optimal endoscopic strategies for such cases remain unknown. AIM To explore the feasibility and effectiveness of single balloon enteroscopy-assisted (SBE-assisted) therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis based on multi-disciplinary collaboration between endoscopists and surgeons as well as report the experience from China. METHODS This is a single center retrospective study. All of the SBE-assisted therapeutic ERCP procedures were performed by the collaboration between endoscopists and surgeons. The operation time, success rate, and complication rate were calculated. RESULTS Forty-six patients received a total of 64 SBE-assisted therapeutic ERCP procedures, with successful scope intubation in 60 (93.8%) cases and successful diagnosis in 59 (92.2%). All successfully diagnosed cases received successful therapy. None of the cases had perforation or bleeding during or after operation, and no post-ERCP pancreatitis occurred. CONCLUSION Based on multi-disciplinary collaboration, SBE-assisted therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis is relatively safe and effective and has a high success rate.

Right hemicolectomy combined with duodenum-jejunum Roux-en-Y anastomosis for hepatic colon carcinoma invading the duodenum:A single-center case series

BACKGROUND Hepatic colon carcinoma invading the duodenum is not common in clinical practice.Surgical treatment of colonic hepatic cancer that invades the duodenum is difficult,and the surgical risk is high.AIM To discuss the efficacy and safety of duodenum-jejunum Roux-en-Y anastomosis for the treatment of hepatic colon carcinoma invading the duodenum.METHODS From 2016 to 2020,11 patients from Panzhihua Central Hospital diagnosed with hepatic colon carcinoma were enrolled in this study.Clinical and therapeutic effects and prognostic indicators were retrospectively analyzed to determine the efficacy and safety of our surgical procedures.All patients underwent radical resection of right colon cancer combined with duodenum-jejunum Roux-en-Y anastomosis.RESULTS The median tumor size was 65 mm(r50-90).Major complications(ClavienDindoI-II)occurred in 3 patients(27.3%);the average length of hospital stay was 18.09±4.21 d;and only 1 patient(9.1%)was readmitted during the 1st mo after the surgery.The 30-d mortality rate was 0%.After a median follow-up of 41 m(r7-58),the disease-free survival at 1,2,and 3 years was 90.9%,90.9%and 75.8%,respectively;the overall survival at 1,2,and 3 years was 90.9%.CONCLUSION In selected patients,radical resection of right colon cancer combined with duodenum-jejunum Roux-en-Y anastomosis is clinically effective,and the complications are manageable.The surgical procedure also has an acceptable morbidity rate and mid-term survival.

Magnetic compression anastomosis for reconstruction of digestive tract after total gastrectomy in beagle model

BACKGROUND Magnetic compression anastomosis(MCA)is a simple procedure contributing to a reliable anastomosis.However,digestive-tract reconstruction after total gastrectomy using MCA has not yet been reported.AIM To investigate the feasibility of MCA for simultaneous esophagojejunostomy and jejunojejunostomy after total gastrectomy using beagle dogs.METHODS Sixteen beagles were randomly divided into an MCA group(study group,n=8)and a manual-suture anastomosis group(control group,n=8).Two different magnetic anastomosis devices were used in the study group for esophagojejunal and jejunojejunal anastomoses.Both devices included a pair of circular daughter and parent magnets each.The time of esophagojejunostomy and jejunojejunostomy,postoperative complications,and survival rate of the two groups were compared.The dogs were sacrificed one month after the operation and their anastomotic specimens were obtained.Healing was observed by the naked eye and a light microscope.RESULTS Digestive-tract reconstruction after total gastrectomy was successfully completed in both groups(survival rate=100%).In the study group,esophagojejunal and jejunojejunal anastomoses took 6.13±0.58 and 4.06±0.42 min,respectively,significantly lower than those in the control group(15.63±1.53 min,P<0.001 and 10.31±1.07 min,P<0.001,respectively).Complications such as bleeding,anastomotic leakage,and anastomotic stenosis were not observed.In the study group,the magnets did not interfere with each other.Discharge time of the jejunojejunal magnetic anastomosis device was 10.75±1.28 d,while that of the esophagojejunal magnetic anastomosis device was 12.25±1.49 d.Residual silk was found in the control group.The study group showed a greater smoothness of the anastomosis than that of the control group.All layers of anastomosis healed well in both groups.CONCLUSION MCA is a safe and feasible procedure for digestive-tract reconstruction after total gastrectomy in this animal model.

胆肠改良襻式吻合术与Roux-en-Y吻合术的临床对比分析

目的比较胆肠改良襻式吻合术与Roux-en-Y吻合术的疗效。方法收集139例行胆肠改良襻式吻合术及120例行胆管空肠Roux-en-Y吻合术胆道重建患者的临床资料,比较其手术时间、术中出血量、肠道功能恢复时间及出院时间,并观察2组间术后并发症的差异。结果与胆管空肠Roux-en-Y吻合术组比较,胆肠改良襻式吻合术组的手术时间更短,患者术中出血更少、肛门排气时间及住院时间均更短(P均<0.05)。术后出现胆汁漏在胆肠改良襻式吻合术组为4例(2.9%),低于Roux-en-Y吻合术组的13例(10.8%),P<0.01。术后2组患者的急性胆管炎和胃排空障碍发生率比较差异均无统计学意义(P均>0.05)。结论胆肠改良襻式吻合术更符合生理,术后恢复较快,发生胆汁漏出风险较低,优于胆管空肠Roux-en-Y吻合术。

Myoelectric activity and motility of the Roux limb after cut or uncut Roux-en-Y gastrojejunostomy

AIM: To explore the mechanisms of uncut Roux-en-Y gastrojejunostomy, which is used to decrease the occurrence of Roux stasis syndrome.METHODS: The changes of myoelectric activity, mechanic motility and interstitial cells of Cajal (ICC) of the Roux limb after cut or uncut Roux-en-Y gastrojejunostomy were observed. RESULTS: When compared with the cut group, the amplitude (1.15 ± 0.15 mV vs 0.48 ± 0.06 mV, P < 0.05) and frequency (14.4 ± 1.9 cpm vs 9.5 ± 1.1 cpm, P < 0.01) of slow waves and the incidence (98.2% ± 10.4% vs 56.6% ± 6.4%, P < 0.05) and amplitude (0.58 ± 0.08 mV vs 0.23 ± 0.06 mV, P < 0.01) of spike potential of the Roux limb in the uncut group were significantly higher. The migrating myoelectric complexes (MMC) phase Ⅲ duration in the uncut group was significantly prolonged (6.5 ± 1.1 min vs 4.4 ± 0.8 min, P < 0.05), while the MMC cycle obviously shortened (42.5 ± 6.8 vs 55.3 ± 8.2 min, P < 0.05). Both gastric emptying rate (65.5% ± 7.9% vs 49.3% ± 6.8%, P < 0.01) and intestinal impelling ratio (53.4% ± 7.4% vs 32.2% ± 5.4%, P < 0.01) in the uncut group were significantly increased. The contractile force index of the isolated jejunal segment in the uncut group was significantly higher (36.8 ± 5.1 vs 15.3 ± 2.2, P < 0.01), and the expression of c-kit mRNA was significantly increased in the uncut group (0.82 ± 0.11 vs 0.35 ± 0.06, P < 0.01). CONCLUSION: Uncut Roux-en-Y gastrojejunostomymay lessen the effects of operation on myoelectric activity such as slow waves, spike potential, and MMC, decrease the impairment of gastrointestinal motility, and remarkably increase the expression of c-kit mRNA.

Roux-en-Y choledochojejunostomy using novel magnetic compressive anastomats in canine model of obstructive jaundice

BACKGROUND:The traditional hand-sewn Roux-en-Y choledochojejunostomy is technically complicated,and the incidence of postoperative complications has remained high.A set of novel magnetic compressive anastomats was introduced to facilitate choledochojejunostomy and improve the prognosis of patients.METHODS:After ligating the common bile duct for 7 days,16 dogs were randomly divided into two groups (n=8 per group).Anastomats were used in the study group,and the traditional hand-sewn method was used in the control group for standard Roux-en-Y choledochojejunostomy.We compared the operation time,incidence of complications,gross appearance,and pathological disparity in stoma between the two groups in 1-month and 3-month follow-up examinations.RESULTS:The time spent on constructing the anastomosis for the study group was significantly shortened.Although no anastomotic stenosis occurred in the two groups,the narrowing rate of biliary-enteric anastomosis was much higher in the control group.There was one case of bile leakage in the control group,whereas no bile leakage occurred in the study group.A smoother surface,an improved layer apposition,and a lower local inflammatory response were identified in the anastomosis of the study group.CONCLUSION:The structures of the novel magnetic compressive anastomats are simple,and they are time-saving,safe and efficient for performing Roux-en-Y choledocho- jejunostomy procedures in a canine model of obstructive jaundice.

Fertility outcome analysis after modified laparoscopic microsurgical tubal anastomosis

Modified laparoscopic microsurgical tubal anastomosis is an alternative for microsurgical anastomosis via laparotomy to reverse sterilization in women with renewed child wish.The current study aims to evaluate the fertility outcome after modified laparoscopic microsurgical tubal anastomosis.A retrospective study was performed.Fifty-eight women who underwent modified laparoscopic microsurgical tubal anastomosis were monitored to investigate the fertility outcome and characteristics of this new technology.Of the 58 patients,the cumulative pregnancy rate(PR)in the 42 patients with follow-up data was 23.8%(10/42),57.1%(24/42),66.7%(28/42),and 73.8%(31/42)within 6,12,24,and 36 months after surgery,respectively.The intrauterine PR was 69.0%(29/42).Two patients(4.8%)had ectopic pregnancies that occurred within 24 months of surgery;three cases ended in spontaneous abortion.The delivery rate was 83.9%(26/31).The length of operating time was 1.2
0.3 h,with a range of 1.0–2.5 h(60–145 min),and the mean time was approximately 75 min.The blood loss was relatively small,between 10 and 50 ml with an average amount of 22 ml.Thus,the modified laparoscopic tubal anastomosis is a highly successful procedure and a viable alternative to open abdominal microsurgical approaches.Compared with the traditional laparoscopic tubal sterilization reversal,this modified approach has three advantages:(1)less invasive approach via a trocar reduction;(2)remodeling of tube is better performing tied together after 3–4 sutures;and(3)faster operating time.
