1/49. An extrahepatic bile duct metastasis from a gallbladder cancer mimicking Mirizzi's syndrome.We report a case of an extrahepatic bile duct metastasis from a gallbladder cancer that mimicked Mirizzi's syndrome on cholangiography. A 67-yr-old woman was admitted to our hospital with a diagnosis of acute calculous cholecystitis. As obstructive jaundice developed after the admission, percutaneous transhepatic biliary drainage was performed to ameliorate the jaundice and to evaluate the biliary system. Tube cholangiography revealed bile duct obstruction at the hepatic hilus, and extrinsic compression of the lateral aspect of the common hepatic duct, with nonvisualization of the gallbladder. No impacted cystic duct stone was visualized on CT or ultrasonography. laparotomy revealed a gallbladder tumor as well as an extrahepatic bile duct tumor. We diagnosed that the latter was a metastasis from the gallbladder cancer, based on the histopathological features. This case is unique in that the extrahepatic bile duct metastasis obstructed both the common hepatic duct and the cystic duct, giving the appearance of Mirizzi's syndrome on cholangiography. Metastatic bile duct tumors that mimic Mirizzi's syndrome have not been previously reported. The presence of this condition should be suspected in patients with the cholangiographic features of Mirizzi's syndrome, when the CT or ultrasonographic findings fail to demonstrate an impacted cystic duct stone.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/49. Pancreatic hydatid cyst.A patient with primary hydatid cyst involving the tail of the pancreas and treated successfully by distal pancreatectomy is reported. Additionally, we performed splenectomy because the spleen was lifted on to the cyst, and cholecystectomy for cholelithiasis.- - - - - - - - - - ranking = 0.29347096344701keywords = spleen (Clic here for more details about this article) |
3/49. Unexpected gallbladder cancer after laparoscopic cholecystectomy: an emerging problem? Reflections on four cases.gallbladder cancer (GC) has been reported in 0.3-1.5% of cholecystectomies. Since the introduction of laparoscopic surgery, cholecystectomies have increased and occult GC may therefore be more frequent. Herein we analyze our own experience to determine whether there was an increase in GC. We also evaluate the risk factors for this outcome. Four patients with GC undiagnosed before surgery (four of 602 cases, or 0.66%) were submitted to laparoscopic cholecystectomy. The percentage in patients who underwent open surgery was 0.28% (two of 714 cases). Without reoperation, three patients died in the laparoscopic group and one is alive at 12 months. Trocar site metastasis was not observed. Although the percentage of GC (0.28% versus 0.66%) increased, the percentage is still in the referred average. Undiagnosed GC is on the increase. Examination of the gallbladder and a frozen section, if necessary, are recommended. Calcified gallbladders, age >70 years, a long history of stones, and a thickened gallbladder all represent significant risk factors.- - - - - - - - - - ranking = 0.83333333333333keywords = cancer (Clic here for more details about this article) |
4/49. Sequential sonographic changes of the gallbladder in hemobilia: case report of a patient with intrahepatic duct stones.The sonographic features of hemobilia in the gallbladder have been reported with variation, including an echogenic mass, hypoechoic mass, and scattered intraluminal echoes. The sequential sonographic changes of hemobilia in the gallbladder were observed in a 59-year-old male patient with bilateral intrahepatic duct stones. The sonograms of hemobilia in the distended gallbladder initially showed a hyperechoic, homogeneous, movable mass-like lesion, 36 hours before the onset of upper gastrointestinal (UGI) bleeding. A hypoechoic mass-like lesion with a hyperechoic ring was found 5 days after the onset of UGI bleeding. A faint hypoechoic mass-like lesion was found 7 days after the onset of UGI bleeding (the day of no further bleeding). Scattered echoic densities were found 9 days after the onset of UGI bleeding, then disappearance of the lesion was noted 12 days after the onset of UGI bleeding. The sonographic patterns of hemobilia in the gallbladder vary depending on the timing of lysis of the blood clot. It should be differentiated from gallbladder cancer, a stone, a polyp, sludge, acute gangrenous cholecystitis, and gallbladder empyema.- - - - - - - - - - ranking = 0.16666666666667keywords = cancer (Clic here for more details about this article) |
5/49. Laparoscopic cholecystectomy in two patients with symptomatic cholelithiasis and situs inversus totalis.BACKGROUND: situs inversus viscerum is a rare condition with a genetic predisposition. We report 2 patients with situs inversus totalis and symptomatic cholelithiasis successfully treated via laparoscopic cholecystectomy. patients AND methods: The first patient was a 61-year-old female presenting with pain in the left upper quadrant associated with fever, chills, nausea and vomiting. The abdomen was tender with guarding and rebounding pain in the same region. Abdominal ultrasound and CT scan confirmed the diagnosis of gallstones as well as situs inversus with the liver and gallbladder on the left side and the spleen on the right. The second patient was a 37-year-old male with known situs inversus who presented with biliary colic due to cholelithiasis. In both patients cholecystectomy was performed laparoscopically in a reverse fashion. RESULTS: Laparoscopic cholecystectomy was carried out successfully despite the reversed anatomic relationships and both patients made a smooth recovery. CONCLUSION: cholelithiasis occurring with situs inversus totalis is rare and may present a diagnostic problem. Laparoscopic cholecystectomy can be safely and effectively applied in the setting of situs inversus, although attention must be paid to the details of left-right reversal.- - - - - - - - - - ranking = 0.29347096344701keywords = spleen (Clic here for more details about this article) |
6/49. Incidental gallbladder cancer at laparoscopy: a review of two cases.Early peritoneal seeding and trocar site metastasis from gallbladder cancer have been reported after laparoscopic cholecystectomy. Nevertheless, the role of laparoscopy in gallbladder cancer remains controversial. Two cases of early recurrence of carcinoma of the gallbladder after laparoscopic cholecystectomy are described. In the first case, the use of a gasless technique did not prevent an early, diffuse peritoneal dissemination of the disease. In the second case, despite the use of a retrieval bag to extract the gallbladder, multiple metastases around the gallbladder bed and local peritoneal seeding developed. These cases demonstrate that factors other than bile spillage, CO2 inflation, and the use of a retrieval bag are responsible for early dissemination of gallbladder cancer.- - - - - - - - - - ranking = 1.1666666666667keywords = cancer (Clic here for more details about this article) |
7/49. Two incidental cases of abdominal aortic aneurysm and gallbladder cancer. Further data influencing the management of patients affected by aneurysm and gallbladder disease.Abdominal aortic aneurysm and cholelithiasis are two common diseases in the elderly population. The prevalence of abdominal aortic aneurysms ranges between 1.8 and 6.6% in autoptic series and it's estimated that 2.5% of the over sixty year old population is affected. carcinoma of the gallbladder is the most common malignant tumor of the biliary tract and in the united states is the fifth most frequent digestive tract malignancy; it's incidence ranges between 2 to 10 cases of 100,000 persons/year. No adequate guidelines are now available to assist the surgeon, in the case of concomitant gallbladder disease and abdominal aortic aneurysm. In this paper the management of abdominal aortic aneurysm in a patient with gallbladder disease is discussed in order to assist the surgeon deciding whether to perform concomitant aneurysm resection and cholecystectomy. In 162 aneurysmectomies (1987-1997) 18 (11.11%) patients underwent combined aneurysmectomy and cholecystectomy operation. The patients ranged in age from 49 to 88 years (average 69 years). In two cases the anatomo-histological specimen examinations (twelve sections) demonstrated a gallbladder carcinoma. The overall mortality rate was 5.56% either for aneurysmectomy alone or for combined therapy. In case of abdominal aortic aneurysm and concomitant gallbladder disease, in choosing simple endoaneurysmectomy, the surgeon has to consider the risk of early and late complications of leaving a diseased gallbladder in place. In case of concomitant performance of both operations, the risks of a possible septic graft contamination must be considered. We believe that the patient may be best served by performing the vascular and nonvascular procedures in the same operation. In this paper a new proof, till now never considered in the international literature, is presented to support our opinion: the possibility of concomitant unknown cancer or precancerous lesions in a lithiasic gallbladder. diagnosis of these lesions is, indeed, not easy to perform in the preoperative phase and is often a postoperative anatomo-histological detection.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
8/49. Stromal tumor of the gallbladder with phenotype of interstitial cells of cajal: a previously unrecognized neoplasm.We report a small, well-demarcated stromal tumor of the gallbladder in a 69-year-old woman. The tumor and associated cholelithiasis led to chronic cholecystitis symptoms. The wall of the gallbladder contained a 2.4-cm hypocellular nodule composed of bland spindle-shaped cells that were immunoreactive for vimentin, CD34, and CD117. With the latter antibody, which stains interstitial cells of cajal (ICC), the neoplastic cells appear fusiform with elongated bipolar projections or dendritic-like cytoplasmic projections. The gallbladder wall adjacent to the tumor contained numerous CD117-positive cells in close contact with the normal smooth muscle cells, whereas two of 10 gallbladders with minimal chronic cholecystitis showed only a few CD117-positive cells. These findings provide evidence that this stromal tumor of the gallbladder shows ICC differentiation similar to some stromal tumors of the gut. The presence of numerous ICC in the uninvolved gallbladder wall suggests that this tumor might have evolved through hyperplasia of ICC.- - - - - - - - - - ranking = 0.022874426752427keywords = neoplasm (Clic here for more details about this article) |
9/49. A case of intrahepatic gallstone formation around nylon suture for hepatectomy.A 69-year-old female underwent left lobectomy for hepatolithiasis in February 1994. She was admitted to the Kurume University Hospital in December 1997 because computed tomography (CT) showed calcification in the porta hepatis. ultrasonography (US) revealed a hyperechoic area with an acoustic shadow in the right hepatic duct. Dilated intrahepatic bile ducts and a mural lucent area in the right hepatic duct were noted on endoscopic retrograde cholangiography (ERC). Although the above findings suggested a diagnosis of recurrent hepatolithiasis, percutaneous transhepatic biliary drainage (PTBD) for biopsy was performed in order to rule out cancer. biopsy showed no evidence of malignancy. Under a cholangioscope, a tip of a nylon suture was found to be protruding into the bile duct. Although a gallstone had already slipped off, the surface of the nylon suture was covered with biliary sludge. The protruding tip of the nylon suture was considered to be the nucleus of the stone. The tip was removed under cholangioscopy. Postoperative CT confirmed the absence of calcification in the porta hepatis. There has been no recurrence of hepatolithiasis after surgery. Although the formation of gallstones around the core of nylon sutures is very rare, absorbable sutures should be used during surgery of the bile duct because nonabsorbable sutures can become the nucleus of gallstones.- - - - - - - - - - ranking = 0.16666666666667keywords = cancer (Clic here for more details about this article) |
10/49. Implantation metastasis following external biliary drainage in biliary tract cancers--cause for concern!Three patients with periampullary cancer developed tumor seedings along the T-tube choledochostomy tract, thus precluding curative resection in two patients and an early recurrence at the choledochostomy exit site in the third patient. External biliary drainage and intraoperative bile spill should be avoided in patients with curable biliary tract neoplasms.- - - - - - - - - - ranking = 0.83905194002144keywords = cancer, neoplasm (Clic here for more details about this article) |
