ObjectiveTo investigate the value of magnetic resonance (MR) imaging in the assessment of bile duct complications after cholecystectomy. MethodsFifty patients of having bile duct complications after cholecystectomy underwent MR imaging and had some positive manifestations. The indication for cholecystectomy was symptometic cholelithiasis in all cases. MR imaging was performed with a 1.5T clinical imager including all of the sequences of: ①T1 weighted imaging (T1WI) was performed in transverse and coronal plane before and after gadolinium-enhanced. ②T2 weighted imaging (T2WI) was performed in transverse plane. ③A true fast imaging with steadystate precession sequence (True fisp) was performed in coronal plane. ④MR cholangiopancreatography was also obtained. ResultsThe bile duct complications after cholecystectomy including: 22 cases of cholelithiasis, 15 cases of chronic cholangitis with or without bile duct abscess. Bile duct strictures or abruption at the confluence of hepatic and common bile duct in 6 and 3 cases respectively. Tumors of bile duct or pancreas in 9 cases. The other complications after cholecystectomy including bile leak with choleperitonitis and/or biloma and acute pancreatitis.ConclusionMR imaging was a valuable method for the assessment of bile duct complications after cholecystectomy. MR imaging could assess the etiology of bile duct complications. If there were bile duct obstruction, MR imaging could assess the location and the severe of obstruction. For bile duct or pancreatic tumors, MR imaging could assess the areas of tumor infiltration and resection and was helpful to select treatment methods. Before lapatoscopic cholecystectomy, the overall and careful imaging assessment for bile duct and gallbladder and its adjacent hepatic tissue and pancreas so to avoid missing the relative tumors.
【 Abstract 】 Objective To investigate the cause, management and prevention of biliary fistula with un-typical after laparoscopic cholecystectomy (LC). Methods Twenty-one cases of biliary fistula with un-typical after LC were reviewed retrospectively. Results All patients displayed with un-typical expression and had no obvious signs of peritonitis. Lump of right upper quadrant (6 cases) ， vague pain of epigastric zone (11 cases) ， abdominal distention (3 cases) and bowel obstruction (1 case) after operation were main manifestations. Abdominal paracentesis (14 cases) ， bile exuded from incisional opening of trocar (6 cases) and exploratory laparotomy (1 caes) were the methods of final diagnosis. The cause of biliary fistula included cystic stump fistula (2 cases) ， aberrant bile-duct fistula (9 cases) ， and accessory hepatic duct fistula (4 cases). Laparoscopic approach and puncturation and drainage under ultrasound were the main therapeutic methods. All patiens were discharged successfully with no death case. Nineteen cases were followed up for 3 months to 2 years, and all patients recovered very well. Conclusion The biliary fistula with un-typical after LC is scarce ， and it can lead to missed diagnosis and treatment. Strengthening recognition of biliary fistula after LC ， and paying attention to chief complaint and abdominal sign can help discover biliary fistula early. Laparoscopic approach and puncturation under ultrasound are the recommended therapeutic methods.
Objective To investigate the effect of cholecystectomy on the induction of large intestine cancer and its mechanism. Methods After cholecystectomy, the large intestine neoplasm in mice was induced with dimethylhydrazine(DMH).The histogenesis and growth pattern of large intestine cancer were observed.The Sphase fraction (SPF) of epithelium cells in large intestine mucosa was determined using flow cytometry. Before and after operation, the feces of mice were collected to determine the cholic acid (CA), chenodeoxycholic acid (CDCA), deoxycholic acid (DCA) and lithocholic acid (LCA) concentration by highperformance liquid chromatography. Results The average number of large intestine neoplasms per mouse,percentage of large intestine adenomas in examined mice and SPF of experimental group were significantly higher than those of control group (P＜0.05). The fecal LCA concentration in postcholecystectomy was significantly higher than that in precholecystectomy and in sham operation group (P=0.00). Conclusion The large intestine neoplasm of mice induced by DMH is increased and the proliferation of epithelium cell in large intestine mucosa is increased after cholecystectomy. This suggests that cholecystectomy has promoting effect on induction of large intestine neoplasm in mice. The gut may deal with the increased secondary bile acid(LCA) concentration postcholecystectomy.
ObjectiveTo investigate and compare the advantages and disadvantages of laparoscopic cholecystolithotomy and laparoscopic cholecystectomy for patients with gallbladder stone. MethodsThe eligible patients with gallbladder stones hospitalized in our department between January 2007 and December 2011 were included, and all of them received either laparoscopic cholecystolithotomy (observation group) or laparoscopic cholecystectomy (control group) minimally-invasive surgery. The operation time, bleeding volume, enterokinesia recovery time, hospital stay, post-operative complication and follow-up results were compared between the two groups. ResultsA total of 148 patients were included, with 68 patients in the observation group and 80 patients in the control group. In this cohort, the success rate of surgery for the observation group and the control group was 100.0% (68/68) and 98.8% (79/80), respectively; and the success rate of complete stone removal was 100% for both two groups. B-ultrasound examination after 2 weeks of treatment showed that gallbladder wall was normal and gallbladder contraction rate was more than 30% for all patients with laparoscopic cholecystolithotomy. The operation time was (49.6±5.2) minutes for the observation group and (50.5±6.2) minutes for the control group, and bleeding volume was (9.5±1.4) mL for the observation group and (50.2±8.1) mL for the control group; the difference in bleeding volume was significant between the two groups (P<0.05). The difference in enterokinesia recovery time[(33.9±2.2) and (34.4±2.6) minutes] or hospital stay[(3.4±1.0) and (3.6±1.2) days] between the observation group and the control group was not significant (both P >0.05). The post-operative complications of bleeding, bile leakage and wound infection were not observed in both two groups, and all patients were followed up for 6 to 12 months with no stone recurrence; and only 2.7% of patients (1/37) had stone recurrence after 3-year follow-up. ConclusionBoth laparoscopic cholecystolithotomy and laparoscopic cholecystectomy procedures are safe and efficient. However, laparoscopic cholecystolithotomy not only reserves gallbladder but also has superiority of less bleeding volume.
Injury of the gallbladder beds on the liver during laparoscopic cholecystectomy of 178 cases for the last year waas analysed. Reoperations in 6 cases with one death due to major postoperative complications. These injuries could be classified into 3 degrees according to extent of liver parenchyma denuded in the bed . Degree Ⅰ, no liver was denuded in the bed with the fibromembranous lining intact (49 cases);Degree Ⅱ, liver denuded area was less than one half of the bed (90 cases);Degree Ⅲ, liver denuded area was greater than half of the bed ( 39 cases). There was close relationship between grade of the bed injury and the postoperative complication. Leaving the lining intact of the bed was most important during the lapatoscopic cholecystectomy in order to prevent complication from the bed. The method was discussed. Drainage of the subhapatic space was suggested when liver bed is denuded.
【Abstract】ObjectiveTo evaluate the injury of common bile duct in immediate removal of the ligation in cholecystectomy. MethodsEighteen healthy Japanese rabbits were selected and divided into three groups randomly: A group treated with simple cholecystectomy, B group with cholecystectomy plus common bile duct crossligation and C group with cholecystectomy plus hepatic bile duct conjunction “Y”type ligation. The ligation was removed after 5 min in B and C groups. The levels of serum transaminase and bilirubin and pathological changes of bile duct and liver in each group were observed respectively. ResultsThere were no statistic difference in the levels of GPT, GOT, total bilirubin (TB), direct bilirubin (DB) and DB/TB on 12 hours before operation and the 1st and 7th day after operation between A and ligation groups (Pgt;0.05). But there were statistic difference in the those indexes and pathological changes of bile duct and liver between A and ligation groups on the 30th and 90th day after operation (Plt;0.05). ConclusionDuring cholecystectomy, immediate removal of common bile duct ligation doesn’t affect shortterm results, but the long-term results are bile duct stricture and obstruction.
ObjectiveTo explore the reliability and safety of diagnosis and treatment for cholecystocolonic fistula during laparoscopic cholecystectomy. MethodsData of patients with cholecystocolonic fistula in department of general surgery, Gansu provincial hospital from Jan 2002 to Dec 2015 were analyzed retrospectively. There were 112 cases diagnosed by routine intraoperative cholangiography from 11 472 laparoscopic cholecystectomy patients, including 33 males and 79 females, age from 58 to 84 years〔(67.4±12.6) years〕. ResultsOne hundred and twelve cases of cholecystocolonic fistula were diagnosed by routine intraoperative cholangiography in laparoscopic cholecystectomy. There were 105 cases of cholecystocolonic fistula performed laparoscopic cholecystectomy and colon repair, and 7 cases performed colostomy, no surgical complications occurred. Seventy cases were followed-up for 6-27 months〔(16.4±5.3)months〕after operation, no long-term complications occurred. ConclusionsThere is a lack of specific symptoms and special diagnosis for cholecystocolonic fistula before operation. Intraoperative cholangiography is a only objective method for diagnosis, and treatment of cholecystocolonic fistula by laparoscopic cholecystectomy and colon repair or colostomy is safe and reliable based on experienced laparoscopic skill.
Objective To summarize the experiences in learning laparoscopic cholecystectomy （LC） and discuss young surgeons how to learn LC scientifically. Method The clinical data of 198 patients received LC by myself since I got the qualification of LC were analyzed retrospectively. Results LC was performed successfully in 187 patients with an average operation time of 68 min. Eleven patients were converted to laparotomy. In these 11 patients， 10 patients because of unclear anatomy in Calot triangle and 1 patient because of uncontrollable bleeding due to pathologic anatomy in Calot triangle caused by gallstone. All 198 patients did not suffer from complications such as severe hemorrhage or injury of biliary duct. Liquid therapy and antibiotics therapy were applied in patients with cholecystitis after LC. Food intake and ambulation were recovered at 12-24h after operation. All the patients were discharged from hospital with anaverage of 2.8d after LC. There was no complications related bile duct injury in all of the patients. Conclusion Managed by hierarchical operations management system， mastering regional physiological and variant anatomy， making use of other open cholecystectomy and laparoscopic simulative learning system well， complying with the learning curve， controlling the indications， contraindications and timing of conversion to laparotomy， young surgeons are able to master LC scientifically， safely， and solidly.
Objective To systematically review the effectiveness and safety of single-incision laparoscopic cholecystectomy (SILC) versus conventional multiport laparoscopic cholecystectomy (CMLC). Methods We electronically searched PubMed, EMbase, The Cochrane Library (Issue 1, 2013), CBM, CNKI, VIP and WanFang Data for randomized controlled trials (RCTs) on SILC versus CMLC from inception to January 1st, 2013. According to the Cochrane methods, the reviewers screened literature, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.2 software. Results Finally, 17 RCTs involving 1 233 patients were included. The results of meta-analysis showed that, compared with CMLC, SILC was lower in 24 h postoperative pain score (visual analogue scale, VAS) (SMD= –0.40, 95%CI –0.76 to –0.04, P=0.03), higher in cosmetic results score (SMD=1.56, 95%CI 0.70 to 2.43, P=0.000 4), and longer in operative time (MD=13.11, 95%CI 7.06 to 19.16, Plt;0.000 1). However, no significant difference was found in 6 h postoperative pain scores (VAS), postoperative complications, port-site hernia and hospital stay between the two groups. Conclusion SILC is a safe and effective technique for the treatment of uncomplicated benign gallbladder diseases, and it has certain advantages compared with CMLC, which is recommended in clinical application.
Objective To study the suitable operation method of elderly patients with acute cholecystitis. Methods The clinical data of 149 elderly patients with acute cholecystitis were retrospectively analyzed. All patients were divided into two groups according to the operation: open cholecystectomy group (OC group, n=76) and laparoscopic cholecystectomy group (LC group, n=73). Some clinical data were compared in this paper such as operation time, blood loss, length of hospital stay, time of resumption of food, time of intestinal function recovery and complications. Results No marked difference was found between OC group and LC group about basic data except WBC count and examination of gallbladder by B ultrasound（P＞0.05）. But there were significant difference in operation time, blood loss, time of resumption of food, time of intestinal function recovery, length of hospital stay and complications between OC group and LC group （P＜0.01）. Conclusion Individualized treatment should be emphasized on elderly patients with acute cholecystitis. Selection of OC or LC to these patients should be based on the clinical condition and taken the safety as the first principle.
