Peri-vater divertieula may interfere with the normal flow of biliary and pancreatic secretion, thus leading to pancreatobiliary diseasa and the very presence of juxtapapillary diverticulum makes cannulation technically difficult and contributes to the low success rate. In this present series, the relationship between duodenal diverticula and age, sex, and biliary-pancreatic pathology was stud.ied in 1400 patients examined with ERCP. The results are as follows. 1) Duodenal diverticula was demonstrated in 73 of 1400 patients(5, 2%). 2) The incidence of duodenal divertieular increased with age and they were more frequent in men. 3) The cannulation of one or both duct system was suecessful in 69 of the 73 patients, the success rate was 94. 5%. 4) The biliary pathology was found in 41 of the 73 patients and the pancreatic pathology in 6 of the 73 patients. The rnost common finding was biliary calculi which were demonstrated in 35 patients(47. 9%).

PURPOSE: Polypoid lesions of the gall bladder (PLG) have a variety of pathologies. Problems exist in the selection of patients for operation and in the operative approach used. We studied the accuracy of the preoperative radiologic diagnosis and suspected risk factors. METHODS: 121 polypoid lesions of gallbladder were sugically treated during 10 years. Preoperative radiologic diagnosis, age, gender, related symptoms, concurrent gallstone, size, shape, number and histologic diagnosis of the ployps were retrospectively reviewed. RESULTS: The average size of malignancy was 23.0 mm, and that of benign tumors was 7.1 mm (P=0.000). The mean age of patients with a malignancy was significant higher than that of those with benign tumor (P=0.000). The preoperative sensitivity of computed tomography for a malignancy was 67.7%. The patients with malignancy more frequently had related symptoms. CONCLUSION: A CT must be considered, for patients with risk factors, even if the ultrasonographic diagnosis was benign. An Age greater than 60 years, a tumor size greater than 10 mm, a solitary polyp, sessile shape, and related symptoms are predictive factors of a malignancy.

A 43-year-old man, who received total gastrectomy five years ago for advanced gastric cancer, underwent a screening colonoscopy and abdominal CT scan. Abdominal CT scan revealed no abnormal findings. Colonoscopy revealed polyps at the rectum, which were removed by polypectomy. The patient did not complain of abdominal pain or discomfort throughout the procedure. But, he developed right upper quadrant abdominal pain on the next day after colonoscopy. Abdominal CT scan revealed the distended gallbladder with mild wall thickening and suspicious sandy stones or sludge in the gallbladder. The patient underwent an open cholecystectomy. Pathology was compatible with acute cholecystitis. We should be aware of and consider cholecystitis in the differential diagnosis for patients with abdominal pain after colonoscopy.

Although most ingested foreign bodies pass through the gastrointestinal tract spontaneously, those that are sharp, pointed, or large require removal to avoid serious complications. Here we report an interesting case of a 60-year-old man who swallowed a clamshell that passed through the pylorus and was caught in the duodenum. Radiologic findings made it look like a biliary stone. Endoscopic retrieval of the clamshell with a Dormia Basket was performed safely and the patient was discharged uneventfully on the day of the procedure.

Hemorrhagic acalculous cholecystitis is an extremely rare but potentially fatal disease if detection is delayed. Its risk factors include critical illness, diabetes, malignant disease, uremia, and bleeding diathesis. This is the first case report in which hemorrhagic acalculous cholecystitis not accompanied by any risk factor. We herein present a case of hemorrhagic acalculous cholecystitis in a previously healthy patient who suffered from acute abdomen.

OBJECTIVETo study the value of digital medical technology in diagnosis and treatment of the hepatolithiasis.

METHODS64-slice spiral computer tomography (CT) scan data of 14 cases (11 female, 3 male; median age, 48 years) with hepatolithiasis admitted from February to September 2008 were collected. The data were imported into medical image proceeding system (MIPS) for sequence segmenting and three-dimensional (3D) reconstruction. The reconstructed models were imported into FreeForm Modeling System for performing simulation surgery with simulation surgical instruments. According to the results of 3D reconstruction and simulation surgery, reasonable operation strategies were chosen. Finally, the value of clinical application of simulation surgery was evaluated according to the findings of clinical operation on hepatolithiasis patients and postoperative T-tube angiography.

RESULTSThe 3D reconstructed models of 14 cases with hepatolithiasis revealed 7 cases of left liver hepatolithiasis, 2 cases of right liver hepatolithiasis, 5 cases of bilateral hepatolithiasis, including 6 cases of hepatolithiasis with common bile duct calculi, 6 cases of biliary system models with absolute stricture, 8 cases with relative stricture. The results were of agreement with clinical diagnosis. A variety of operation plans were simulated before operation. Simulation equipment used in process of simulation surgery was a powerful sense of feedback.

CONCLUSIONSDigital medical technology is helpful to understand the calculi distribution, bile ducts stricture and deformity. Through preoperative training, simulation surgery are able to guide for choosing operative strategies. It reduces the operation risks.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is the most accurate modality in diagnosis of choledocholithiasis. However, it carries some complications. Endoscopic ultrasonography (EUS) is less invasive than ERCP and used for the diagnosis of choledocholithiasis. Recent studies showed that a usefulness of EUS for the diagnosis of small choledocholithiasis without common bile duct (CBD) dilatation. For such a reason, ERCP is being replaced by EUS in the diagnosis of bile duct stones. The aim of this study was to investigate the accuracy of EUS for the diagnosis of choledocholithiasis without CBD dilatation. METHODS: A total of 66 patients with suspected choledocholithiasis without CBD dilatation were enrolled. EUS were performed in all cases within 48 hours after computed tomography (CT) or ultrasonography (US). Final diagnosis was obtained by ERCP or clinical course (minimum 6 months follow-up). We analyzed the accuracy of US, CT, and EUS, respectively. RESULTS: CT and US were performed in 51 and 15 cases, respectively. CBD stones were detected in 23 (35%) patients by ERCP. EUS showed 100% sensitivity, 95% specificity, 92% positive predictive value, and 100% negative predictive value for identifying CBD stones. CT or US showed 26%, 93%, 67%, and 70%, respectively. There were no EUS-related complications. CONCLUSIONS: EUS was more effective than CT or US and as accurate as ERCP for the diagnosis of small choledocholithiasis without CBD dilatation. Thus, EUS may help to avoid unnecessary diagnostic ERCP and its complication.
