1/165. Gas in the bile ducts (pneumobilia) in emphysematous cholecystitis.Gas in the biliary ducts (pneumobilia) was demonstrated in three cases of emphysematous cholecystitis. Pneumobilia is usually secondary to a spontaneous internal biliary fistula or incompetent sphincter of oddi, and is rarely considered a manifestation of emphysematous cholecystitis. The presence of gas in the biliary ducts in these cases suggests that the cystic duct is patent, allowing gas to escape from the gallbladder lumen. The pathophysiology of emphysematous cholecystitis is discussed and an ischemic etiology considered.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
2/165. Peripheral clear cell cholangiocarcinoma: a rare histologic variant.We present the case of a 50-year-old diabetic male who underwent open cholecystectomy for acute gangrenous cholecystitis. At the time of exploration, a 1.5-cm mass was found peripherally in the right lobe of his liver, and an incisional biopsy was performed. Microscopic examination revealed a distinct overgrowth of clear cells in an acinar pattern, with tumor cells emerging directly from bile ducts. The tumor cells were periodic acid-Schiff reactive and diastase resistant, indicating the presence of mucin. No bile canaliculi were demonstrated by immunostaining with carcinoembryonic antigen. CT scans of the chest and abdomen were otherwise normal. Based on these microscopic, immunohistochemical, and clinical data, a diagnosis of clear cell cholangiocarcinoma was established. The patient later underwent reexploration and generous hepatic wedge resection. He did well postoperatively and is free of disease after 12 months.- - - - - - - - - - ranking = 0.14285714285714keywords = duct (Clic here for more details about this article) |
3/165. A case of xanthogranulomatous cholecystitis.Xanthogranulomatous cholecystitis (XGC) is an uncommon, focal or diffuse destructive inflammatory disease of the gallbladder that is assumed to be a variant of conventional chronic cholecystitis. A 36-year-old male was admitted to Chonnam National University Hospital with a 10-day history of right upper quadrant pain with fever. 15 years ago, he was first diagnosed as having hemophilia a, and has been followed up in the department of hematology. Computed tomogram (CT) revealed a well-marginated, uniform, marked wall thickening of the gallbladder with multiseptate enhancement. magnetic resonance imaging (MRI) demonstrated diffuse wall thickening of the gallbladder by viewing high signal foci with signal void lesions. After factor viii replacement, exploration was done. On operation, the gallbladder wall was thickened and the serosa were surrounded by dense fibrous adhesions which were often extensive and attached to the adjacent hepatic parenchyma. There was a small-sized abscess in the gallbladder wall near the cystic duct. dissection between the gallbladder serosa and hepatic parenchyma was difficult. Cross sections through the wall revealed multiple yellow-colored, nodule-like lesions ranging from 0.5-2 cm. There were also multiple black pigmented gallstones ranging from 0.5-1 cm. The pathologic findings showed the collection of foamy histiocytes containing abundant lipid in the cytoplasm and admixed lymphoid cells. Histologically, it was confirmed as XGC. We report a case with XGC mimicking gallbladder cancer in a hemophilia patient.- - - - - - - - - - ranking = 0.14285714285714keywords = duct (Clic here for more details about this article) |
4/165. Right hepatic lobectomy for recurrent cholangitis after bile duct and hepatic artery injury during laparoscopic cholecystectomy: report of a case.A patient is reported who required a right hepatic lobectomy for recurrent cholangitis due to injury of the major bile ducts and the right hepatic artery during laparoscopic cholecystectomy. A 39 year-old woman with acute cholecystitis underwent laparoscopic cholecystectomy. A laparotomy was performed due to a bile duct injury at the hepatic bifurcation. After surgery, she suffered from recurrent cholangitis due to inadequate biliary reconstruction. A right hepatic lobectomy and reconstruction of the left hepatic duct was required because of right hepatic lobe atrophy and recurrent cholangitis. After the 2nd operation, she was active and exhibited no evidence of recurrence at 22 months.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
5/165. intestinal obstruction from midgut volvulus after laparoscopic cholecystectomy. A report of an unusual complication.Congenital midgut malrotation, a rare anatomic anomaly that can lead to duodenal or small bowel obstruction, rarely is recognized beyond the first year of life. We report a case of unrecognized congenital midgut malrotation that resulted in midgut volvulus, causing intestinal obstruction and requiring emergent reoperation after laparoscopic cholecystectomy. This unusual complication, first reported in 1994, involved a 56-year-old man and resulted in cecal infarction recognized and treated on the second postoperative day. This second case describes a less acute postoperative course, with multiple bouts of partial bowel obstruction leading to two readmissions and finally resulting in a reexploration and definitive treatment on the 19th postoperative day.- - - - - - - - - - ranking = 0.23586770715907keywords = obstruction (Clic here for more details about this article) |
6/165. Right hepatic lobectomy for bile duct injury associated with major vascular occlusion after laparoscopic cholecystectomy.A 57-year-old woman underwent laparoscopic cholecystectomy (LC) for cholelithiasis. Continuous bile leak was observed beginning on the first postoperative day. Postoperative endoscopic retrograde cholangiography revealed bile leak through the common hepatic duct, and severe stenosis of the hepatic confluence. A total of three percutaneous transhepatic biliary drainage (PTBD) catheters were inserted to treat obstructive jaundice and cholangitis. The patient was referred to our hospital for surgery 118 days after LC. cholangiography through the PTBD catheters demonstrated a hilar biliary obstruction. Celiac arteriography revealed obstruction of the right hepatic artery, and transarterial portography showed occlusion of the right anterior portal branch. On the basis of the cholangiographic and angiographic findings, we performed a right hepatic lobectomy with hepaticojejunostomy to resolve the bile duct obstruction and address the problem of major vascular occlusion. The patient's postoperative recovery was uneventful and she remains well 25 months after hepatectomy. We discuss a treatment strategy for bile duct injury suspected after LC, involving early investigation of the biliary tree and prompt intervention.- - - - - - - - - - ranking = 5.7692019852381keywords = duct obstruction, duct, obstruction (Clic here for more details about this article) |
7/165. Heterotopic pancreas--an unusual cause of cholecystitis.A 47-year-old woman presented with signs and symptoms of acute cholecystitis. A routine cholecystectomy was performed. No gallstones were present. On histological examination of the gallbladder, a nodule impinging on the lumen was present in the region of the cystic duct. This nodule was composed of mature, uninflamed exocrine and endocrine pancreatic tissue. In the absence of gallstones, the heterotopic pancreas was the cause of obstruction, with subsequent cholecystitis.- - - - - - - - - - ranking = 0.17655252959415keywords = duct, obstruction (Clic here for more details about this article) |
8/165. Cholecystitis caused by hemocholecyst from underlying malignancy.Massive hemobilia is a well recognized clinical entity, particularly when it presents with jaundice, GI bleeding, and biliary pain. However, occult hemobilia is more difficult to diagnose and has seldom been reported because of its clinically silent nature. In fact, this is usually overlooked until complications arise. Hemocholecyst or clot within the gallbladder may rarely occur in this setting, leading to cystic duct obstruction and cholecystitis. Most previous reports describe cholecystitis resulting from hemocholecyst after iatrogenic trauma. We describe two cases in which hemocholecyst occurred from underlying malignancies, both resulting in cholecystitis (acute or chronic).- - - - - - - - - - ranking = 4.8446683546212keywords = duct obstruction, duct, obstruction (Clic here for more details about this article) |
9/165. Preoperative diagnosis of gallbladder torsion by magnetic resonance cholangiopancreatography.The patient was a 78-year-old woman who was diagnosed as having gallbladder torsion preoperatively. This is the first reported case diagnosed by magnetic resonance cholangiopancreatography (MRCP). signs and symptoms of this condition are often subtle. Radiologic evaluation by ultrasonography and computed tomography (CT) showed acute cholecystitis with stone. Drip-infusion cholangiography CT failed to outline the gallbladder, and distortion of the extrahepatic bile ducts and interruption of the cystic duct were observed. MRCP showed 1) a v-shaped distortion of the extrahepatic bile ducts due to traction by the cystic duct, 2) tapering and twisting interruption of the cystic duct, 3) a distended and enlarged gallbladder that was deviated to the midline of the abdomen, and 4) a difference in intensity between the gallbladder and the extrahepatic bile ducts and the cystic duct. A definitive diagnosis of gallbladder torsion (volvulus) was made by MRCP preoperatively. If treated surgically, gallbladder detorsion before cholecystectomy is a helpful technique to avoid bile duct injury. This condition should be suspected in elderly women with acute cholecystitis or acute abdominal pain of unknown origin, and MRCP may be very useful in making a definitive diagnosis.- - - - - - - - - - ranking = 1.1428571428571keywords = duct (Clic here for more details about this article) |
10/165. Bouveret's syndrome: CT findings.intestinal obstruction secondary to gallstones is seen in the older population and the level of obstruction is usually at the level of the terminal ileum. Obstruction at the level of the gastric outlet is called Bouveret's syndrome. A case with perforated cholecystitis and duodenal obstruction due to a gallstone is presented. The CT findings are presented along with the clinical findings and literature review.- - - - - - - - - - ranking = 0.10108616021103keywords = obstruction (Clic here for more details about this article) |
