【Abstract】Objective To analysis the clinical characteristics, pathogenesis, diagnosis and treatment of acute acalculous cholecystitis.Methods Seventy-nine cases of acute acalculous cholecystitis from January 1996 to January 2003 were retrospectively reviewed.Results Of those 79 cases, 13 cases were treated nonoperatively and 66 cases were treated operatively. Twentythree cases were suppurative, 43 cases were gangrenous with perforation in 18 cases，which were proved by postoperative pathology. Seventysix cases were cured and 3 cases were dead. Conclusion Keeping vigilant alert, observing dynamically as well as appropriate operative intervention are effective to improve the prognosis of acute acalculous cholecystitis.
ObjectiveTo explore the etiological agent, clinical manifestations, imaging findings, pathologic characteristics, diagnosis, treatment, and prognosis of xanthogranulomatous cholecystitis(XGC). MethodThe clinical data of 48 patients with XGC diagnosed by postoperative pathology from January 2003 to December 2012 were collected and analyzed. ResultsIn these 48 patients with XGC, the clinical manifestations included 40(83.3%)patients with upper right abdominal pain, 18(37.5%)patients with jaundice, 12(25.0%)patients with fever. B ultrasound examination was performed in 45 cases, in which 42 cases were diagnosed with cholecystitis, 38 cases together with cholecystolithiasis, 15 cases together with cholecystolithiasis and gallbladder neoplasm, and 3 cases together with choledocholith with bile duct dilatation. CT was performed in 30 cases, in which 25 cases were diagnosed with cholecystitis together with cholecystolithiasis, 11 cases were diagnosed with gallbladder neoplasm. MRI was performed in 22 cases, in which 18 cases were diagnosed with cholecystitis together with cholecystolithiasis, 4 cases were diagnosed with gallbladder carcinoma. Thirty-three cases were treated with open cholecystectomy, 9 patients with laparoscopic cholecystectomy, 4 patients with cholecystectomy plus choledocholithotomy and T-tube drainage, 2 patients with cholecystectomy plus partial hepatectomy. All the patients were diagnosed with XGC by postoperative pathology and recovered well without recurrence and canceration. ConclusionsXGC is a kind of benign and invasive disease without specific clinical manifestation. Bultrasound, CT, or MRI play an important role in diagnosis, but final diagnosis is mainly based on pathological detection, and surgery is the most effective treatment. The prognosis of XGC is favorable if gallbladder is completely resected.
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.
ObjectiveTo explore the clinical characteristic, operation time, and methods of elderly calculous cholecystitis. MethodsThe data of 386 cases of elderly calculous cholecystitis in our hospital from January 2008 to April 2014 were retrospectivly analyzed. ResultsIn 386 patients, 234 cases were chronic cholecystitis, 152 cases were acute calculous cholecystitis; there were preoperative complications in 174 cases (45.08%); 234 cases of chronic calculous cholecystitis patients underwent elective operation, 35 cases in 152 cases of acute phase underwent operation at 72 h, the remaining 117 cases underwent operation in within 2 weeks of onset. Laparoscopic cholecystectomy (LC) were in 283 cases, including transfer laparotomy operation in 8 cases; underwent conventional open cholecystectomy in 103 cases. Postoperative complications occurred in 49 cases, the complication rate was 12.69%, including incision infection, pulmonary infection, acute urinary retention, urinary tract infection, biliary fistula and so on. Three hundreds and eighty-four cases were cured, 2 cases died, for cholecystolithiasis complicated with severe acute cholangitis, died from multi organ failure in 3 days after operation. ConclusionsThe clinical characteristics of elderly calculous cholecystitis is unique. To strictly grasp the operation indication, selection of operation time, take individual operation method with the disease, and strengthen treatment of perioperative period are the key to improve the cure rate and the operation success rate of elderly cholecystitis.
【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.
【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.
