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.
This study was designed to determine the effects of different anaesthesia on the postoperative gastrointestinal motility after cholecystectomy. Postoperative gastrointestinal motility were recorded continuously by means of gastrointestinal manometry in 20 patients subject to cholecystectomy (general anaesthesia 10, epidural anaesthesia 10). Normal migrating motor complex (MMC) was abolished during the early postoperative period in all patients. The time of reappearance of intestinal MMC varied from 0.5 to 2 hours . Gastric MMC recurred 5.5 to 14 hours postoperatively and the normal MMC completely recovered 22 to 43 hours after the operations. Ingestion of food changed the MMC into a fed pattern during the early postoperative period. There was no difference between the general anaesthesia group and epidural anaesthesia group in terms of gastrointestinal motility. The results indicate that postoperative gastrointestinal motility recovers faster than that was thought conventionally. Cholecystectomy under general anaesthesia or under epidural anaesthesia makes no difference in postoperative gastrointestinal motility.
Objective To explore whether the intraoperative cholangiography （IOC） should be applied in laparoscopic cholecystectomy routinely or selectively. Methods Data of routine IOC group （1 520 patients）and selective IOC group （457 patients）in laparoscopic cholecystectomy were collected and analyzed， including cholangiography time， success rate， common bile duct stones rate， open cholecystectomy rate， and hospital stay after operation. All IOC cases were performed by home-made cholangiography appliance or infusion needle. Results There were no significant differences between routine IOC group and selective IOC group on cholangiography time， success rate， open cholecystectomy rate， and hospital stay after operation （P＞0.05）. However， compared with routine IOC group， the common bile duct stones rate， anatomic variation rate， and iatrogenic damage rate were significantly higher in selective IOC group （28.25% vs. 13.43%， 10.71% vs. 7.43%， 2.05% vs. 1.02%， P＜0.05）. Conclusions For avoiding iatrogenic bile duct damage and residual stones， routine IOC should be applied in early-stage of laparoscopic cholecystectomy， and IOC should be applied selectively when the surgeon have LC technique at their finger ends.
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 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.
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 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.
Objective To investigate the possibility of laparoscopic cholecystectomy （LC） on porcelain gallbladder. Methods Twenty-four cases of porcelain gallbladder， who were operated in China Medical University， including 13 LC cases， from 2006 to 2008 were retrospectively reviewed. Results Of 24 porcelain gallbladder cases (0.48%) in 4964 cholecystectomy patients， calcification of gallbladder in 87.50%(21/24) patients was diagnosed by ultrasonography. Of 13 patients who were cured by LC, one suffered from postoperative leak bile, no metastasis were found by following up 12 or 14 months in two gallbladder carcinoma cases. Conclusion There’s specificity of ultrasonographic image in porcelain gallbladder, in which LC is safe to be performed and routine frozen pathology during operation is necessary.
ObjectiveTo investigate the feasibility and advantages of general laparoscopic cholecystectomy and gynecologic uterus and attachment surgery at the same time. MethodsSixty patients with gallbladder stones combined with ovarian cysts, benign gynecological disease or fallopian tube adhesions aged between 35 and 55 were chosen from the department of General Surgery and Gynecology and Obstetrics to be the study subjects between January 2009 and December 2013. The inclusion criteria included: gallbladder stones; gallbladder wall thickness <0.5 cm; non-acute inflammation; symptomatic gynecological diseases; and tumor size between 5.0 and 10.0 cm. Based on similar age, body mass, and histological type, the patients were divided into laparoscopic surgery (GLS) group and staging surgery group (control group) according to the will of the patients. The anesthesia time, surgery time, the number of abdominal perforations, length of hospital stay, and total costs were detected for comparison between the two groups. ResultsThe first-time operation was successful in all the patients in the CLS group, with two cases of abnormal liver function, which were cured within 5-6 days. In the control group, 2 cases of reoperation were transferred to laparotomy due to umbilical and peritoneal adhesions, and both of them were cured and discharged from hospital without incision infection or iatrogenic tissue and organ damage. CLS group had significant advantages in anesthesia time, surgery time, the number of abdominal perforations, length of hospital stay, and total costs over the control group (P<0.05). ConclusionThe combined gynecologic laparoscopic surgery is feasible, safe, mini-invasive, and economical.
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.
