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】Objective To investigate the features of gallbladder carcinoma in two-phase spiral CT, and to analysis the values of two-phase spiral CT for the differential diagnosis between gallbladder carcinoma and chronic cholecystitis. Methods The two-phase spiral CT manifestations of 30 cases of gallbladder carcinoma, proved by surgery and pathology, and 30 cases of chronic cholecystitis were analyzed. Results According to the CT findings, the gallbladder carcinoma was categorized into 3 types: intraluminal mass of gallbladder in 6 out of 30 (20.0%）， thickening of the gallbladder wall in 11 (33.7%), and mass replacing the normal gallbladder in 13(43.4%). The most common enhancement patterns of the wall in gallbladder carcinoma were hyperattenuation during the arterial phase, while isoattenuation with the adjacent hepatic parenchyma during the venous phase; or hyperattenuation during both phases. The most common enhancement pattern of the wall in chronic cholecystitis was isoattenuation during both phases, with clear hypoattenuation linear shadow in the gallbladder fossa. Other ancillary features of gallbladder carcinomas included: infiltration of the adjacent parenchyma, local lymphadenopathy and intrahepatic metastasis. Conclusion Two-phase spiral CT scan can identify the features of the gallbladder carcinoma and is helpful for the differential diagnosis of these two different disease entities.
Objective To investigate the diagnostic value of CT scanning and MR imaging on acute cholecystitis. Methods The CT or MR imaging data of 21 patients with proved acute cholecystitis were retrospectively reviewed. Eleven patients were examined with contrast-enhanced multi-detector-row spiral CT scanning and other 10 cases underwent contrast-enhanced MR imaging. Results Nineteen patients showed obscure gallbladder outlines （90.5%）. The gallbladder wall demonstrated even thickening in 15 patients （71.4%） and irregular thickening in 6 cases （28.6%）. All patients showed inhomogeneous enhancement of the gallbladder wall （100%）. The bile was hyper-dense or hyper-intense on T1W image in 11 cases （52.4%）. Ten cases had free peri-cholecystic effusion （47.6%）, and 16 cases had peri-cholecystic adhesive changes or fat swelling （76.2%）. Patchy or linear-like transient enhancement of the adjacent hepatic bed in the arterial phase was seen in 16 cases （76.2%）. Twelve patients developed pleural effusion, or ascites, or both （57.1%）. Gallbladder perforation complicated with peritonitis was seen in one case, micro-abscess formation and pneumocholecystitis was observed in another case, and one case had gallbladder diverticulum. Conclusion Wall blurring, pericholecystic adhesion or fat edema, and transient enhancement of adjacent hepatic bed in the arterial phase are the imaging findings specifically associated with acute cholecystitis, which are readily appreciated on contrast-enhanced multi-phasic CT and MR scanning.
ObjectiveTo explore technical essentials and safety of laparoscopic cholecystectomy (LC) guided by gallbladder ampulla localization on an imaginary clock for cholecystitis.MethodsA retrospective study of 8 707 continuous patients with mild cholecystitis who underwent LC from July 1998 to February 2018 at a single institution was conducted. Among them, 3 168 patients were treated by the traditional LC from July 1998 to February 2007 (a traditional LC group), 5 539 patients were treated by the LC with the guidance of the gallbladder ampulla localization on an imaginary clock from March 2007 to February 2018 (a gallbladder ampulla localization group). The conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury, operative time, intraoperative blood loss, and postoperative hospital stays were compared between the traditional LC group and the gallbladder ampulla localization group.ResultsThere were no significant differences in the gender, age, course of disease, and type of cholecystitis between these two groups (P>0.050). The rates of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury and the operative time, intraoperative blood loss and postoperative hospital stays in the traditional LC group were 3.00% (95/3 168), 0.13% (4/3 168), 0.09% (3/3 168), 0.03% (1/3 168), (43.6±12.6) min, (18.7±3.3) mL, (3.6±2.7) d, respectively, which in the gallbladder ampulla localization group were 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), (32.2±10.5) min, (12.4±3.5) mL, (3.5±2.8) d, respectively. The differences of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding rates, and the operative time and intraoperative blood loss were statistically significant between these two groups (P<0.050). The differences of the bile leakage without bile duct injury rate and postoperative hospital stays were not statistically significant between the two groups (P>0.050).ConclusionThis study shows that gallbladder ampulla localization on an imaginary clock is useful for ductal identification so as to reduce bile duct injury and improve safety of LC in case of no conversion to open surgery.

【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.
