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.
Objective To evaluate the use of fast track surgery （FTS） in the treatment for cholecystolithiasis combined with calculus of common bile duct （CBD） by combination of laparoscope and duodenoscope. Methods One hundred and twenty patients with cholecystolithiasis combined with calculus of CBD underwent laparoscopic cholecyst-ectomy （LC） and endoscopic retrograde cholangiopancreatography （ERCP） were divided into FTS group （n=55） and conventional group （n=65），which were accepted the perioperative therapy of FTS or conventional therapy，respectively. After operation，the incision pain，nausea and vomiting，infusion time，loss of body weight，out-of-bed time，dieting time，postoperative hospitalization，hospital costs，and complications were compared in two groups. Results Compared with the conventional group，the postoperative infusion time，dieting time，out-of-bed time，and postoperative hospitali-zation were shorter，the incidence rates of pulmonary infection，and urinary systems infection，pancreatitis，nausea and vomiting， and incision pain were lower，the loss of body weight was lower in the FTS group （P＜0.05），but the differences of WBC and serum amylase at 24 h after operation were not significant between the FTS group and conventional group（P＞0.05）. Conclusion The FTS is safe，economic，and effective in the treatment for cholecystolithiasis combined with calculus of CBD by combination of laparoscope and duodenoscope.
Analysis of hospital cases of cholelithiasis in every four years of the recent 3 decades clearly shows the tendency of changes of cholelithiasis in clinical appearance in Chengdu.Constituent ratio of gallbladder stone was 12.56% in 70’s,47.54% in 80’s and 81.38% in 90’s.Bill duct stones including acute obstructive suppurative cholangitis was 71.01%, 46.08%,and 15.82% respectively. Biliary ascariasis was 11.67%, 2.75% and 0.68% respectively. Age incidence shows right moving, i.e. old patients increased. Urban patients increased.The influencing factors listed are: improvement of diagnostic methods; improvement of livelihood and diet; increased life expectancy; more health follow up examinations; technical improvements in rural areas and etc.
【Abstract】Objective To study the regulatory ability of peroxisome proliferatoractivated receptor γ(PPARγ) ligands to the inflammatory response in human gallbladder epithelial cells. Methods Culture human gallbladder epithelial cells and identify them . Cells were treated for 24 hours with 0, 10 μmol/L, 20 μmol/L, 30 μmol/L, 50 μmol/L and 100 μmol/L of Ciglitazone during cellular growth peak(5th day), then stimulated them with hIL-1β 5 ng/ml for 2 hours and measured the concentration of IL-6、IL-8 and TNF-α in cellular supernatants by riadioimmunoassay. Results Contrasted with control group, the expression of IL-6 and IL-8 in each test group were inhibited （P＜0.001）. The IL-6 and IL-8 levels were gradually dropped and corelated with the dosage of Cigtitazone, and manifested dosagedependence (P＜0.001). The concentration of TNF-α could not be measured. Conclusion PPARγ ligands can inhibit the expression of IL-6 and IL-8 in human gallbladder epithelial cells and probably produce effect in the regulation of cholecystic inflammation.
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.
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.
【Abstract】ObjectiveBy using multidetector row spiral CT (MDCT) to investigate the CT imaging findings of gallbladder abnormalities caused by hepatic parenchymal diseases and those of inflammatory cholecystitis. MethodsCT and clinical data of 80 patients with gallbladder abnormalities were retrospectively reviewed. Fifty patients were in hepatic disease group, including 20 chronic hepatitis, 25 liver cirrhosis, and 5 cirrhosis with hepatocellular carcinoma. Thirty patients were in inflammatory group, including 19 chronic cholecystitis, 6 acute cholecystitis, 3 cholecystitis with acute pancreatitis, 1 gangrenous cholecystitis, and 1 xanthogranulomatous cholecystitis. All patients underwent MDCT plain scan and contrastenhanced dualphase scanning of upper abdomen. ResultsIn hepatic disease group, 48 cases had evenly thickened gallbladder wall (96%) with mean thickness of (3.67±0.49) mm; 38 cases had clear gallbladder outlines (76%); 38 cases had gallbladder wall enhancement of various degree (76%); 14 cases had gallbladder bed edema and localized nondependant pericholecystic fluid collection (28%). In inflammatory cholecystitis group, 28 cases had obscuring gallbladder outlines (93%) ; 26 cases had gallbladder wall evenly thickened (87%), 4 cases showed unevenly thicked wall (13%), the mean thickness being (4.54±1.14) mm; 30 cases had inhomogenous enhancement of the gallbladder wall (100%); 9 cases had highattenuation bile (30%); 4 cases had dependant pericholecystic fluid collection (13%); 5 cases had transient enhancement of adjacent hepatic bed in arterial phase (17%); microabscess and gas in the gallbladder wall was observed in 1 case respectively. ConclusionMDCT can offer imaging findings useful for differentiating abnormal gallbladder changes caused by hepatic parenchymal diseases from those due to inflammatory cholecystitis.
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 of “three holes and one hook in the end (TOE)” laparoscopic cholecystectomy (LC) in 1 260 cases and to investigate the operation procedures, technical points and the prevention of complications. Methods The data of 1 260 patients suffering from chronic calculous cholecystitis, acute calculous cholecystitis, atrophic cholecystitis, gallbladder polyps etc., who were admitted to this hospital and treated by TOE from March 1999 to March 2008 were included and analysed retrospectively in this study. Results One thousand two hundred and sixty of cases were cured, including 1 252 cases of succeeding LC (99.37%), conversions to open in 8 cases, no death, no bile duct injury, with intraoperative hemorrhage in 3 cases, umbilicus infection in 2 cases, gallbladder fossa hydrops in 3 cases, with operation time for 8-60 min (mean 38.5 min) and hospitalization for 3-7 d (mean 5 d ) after surgery. During the follow up of 1 002 cases for 1 to 7 years (mean 3.5 years), there were no complications such as bile fistula, bile duct stricture, residual stones of biliary duct, etc.. Conclusion TOE is worthy of application and promotion for the excellent effectiveness, few complications, rapid recovery and safety.
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.
