1/24. Successful nonoperative management of neonatal acute calculous cholecystitis.Acute cholecystitis in the neonate is rare and usually treated by cholecystectomy. A 1-day-old full-term girl had clinical and sonographic features of acute calculous cholecystitis. This was successfully managed nonoperatively with intravenous fluids and antibiotics, leading to complete resolution of the condition. The infant currently is thriving and asymptomatic with a sonographically normal biliary tree. Spontaneous resolution of cholelithiasis may occur in neonates, even in the presence of acute cholecystitis.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/24. Recanalization of a portal-vein thrombosis and partial resolution of biliary cirrhosis following cholecystectomy for cholelithiasis in an infant.cholelithiasis in infants and children is unusual and is reputedly associated with underlying hemolytic disorders, total parenteral nutrition, ileal disease, and congenital anomalies of the biliary tree. We report a case of cholecystitis with pigmented stones in a 3-month-old infant associated with portal vein thrombosis (PVT) and biliary cirrhosis without the above-mentioned causes. Recanalization of the PV and partial resolution of the cirrhosis was observed following cholecystectomy. To our knowledge, cholelithiasis associated with PVT and cirrhosis in an infant has not been reported in the literature.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
3/24. Acute cholecystitis secondary to hemobilia.Invasive diagnostic and therapeutic techniques such as percutaneous transhepatic cholangiography, endoscopic retrograde cholangiopancreatography (ERCP), transjugular intrahepatic portosystemic shunting, and laparoscopic cholecystectomy have led to a rise in hemobilia. Most complications from hemobilia are attributable to acute blood loss; other complications are secondary to thrombus formation in the biliary tree. We present a case report of acute cholecystitis secondary to hemobilia after percutaneous liver biopsy. The role of ERCP in the diagnosis and treatment of this exceedingly rare event is discussed.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
4/24. 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 = 1keywords = tree (Clic here for more details about this article) |
5/24. mirizzi syndrome. Case presentation with review of the literature.mirizzi syndrome is a rare pathology of the extrahepatic biliary system caused by a large gallbladder calculous either compressing or eroding into the collecting biliary tree. This paper describes a case of mirizzi syndrome with atypical presentation. A review of the literature including diagnostic and therapeutic modalities are reported.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
6/24. Isolation and characterization of a salmonella enterica serotype Typhi variant and its clinical and public health implications.We report the isolation and characterization of a member of the family enterobacteriaceae isolated from the gallbladder pus of a food handler. Conventional biochemical tests suggested salmonella enterica serotype Typhi, but the isolate agglutinated with poly(O), 2O, 9O, and Vi Salmonella antisera but not with poly(H) or any individual H Salmonella antisera. 16S rRNA gene sequencing showed that there were two base differences between the isolate and salmonella enterica serotype Montevideo, four base differences between the isolate and serotype Typhi, five base differences between the isolate and salmonella enterica serotype Typhimurium, and six base differences between the isolate and salmonella enterica serotype Dublin, indicating that the isolate was a strain of S. enterica. Electron microscopy confirmed that the isolate was aflagellated. The flagellin gene sequence of the isolate was 100% identical to that of the H1-d flagellin gene of serotype Typhi. Sequencing of the rfbE gene, which encoded the CDP-tyvelose epimerase of the isolate, showed that there was a point mutation at position 694 (G-->T), leading to an amino acid substitution (Gly-->Cys). This may have resulted in a protein of reduced catalytic activity and hence the presence of both 2O and 9O antigens. We therefore concluded that the isolate was a variant of serotype Typhi. Besides antibiotic therapy and cholecystectomy, removal of all stones in the biliary tree was performed for eradication of the carrier state.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
7/24. Hepatobiliary and pancreatic infections in AIDS: Part II.In the first part of our review, we discussed the general evaluation and clinical presentation of the various hepatic infections occurring in patients with AIDS. In addition, we focused on specific hepatic parenchymal infections. In this article, we will discuss the major clinical syndromes arising from opportunistic infections affecting the gallbladder (acalculous cholecystitis), biliary tree (AIDS-cholangiopathy), and pancreas (pancreatitis). acalculous cholecystitis can develop in patients with AIDS who have not experienced the severe precipitating physiologic stresses normally required in patients without AIDS. The most common presentation is with right upper quadrant (RUQ) pain and tenderness. The diagnosis is a clinical one since there is no standard test, other than surgery. cholecystectomy is the treatment of choice. The most common AIDS-associated infective complication of the biliary tree is AIDS-cholangiopathy. This is best viewed as a form of secondary sclerosing cholangitis resulting from a variety of opportunistic infections within the biliary tree. Affected persons present with RUQ pain and have marked elevations in the canalicular enzymes, alkaline phosphatase, and gamma-glutamyl transferase. Morphologic abnormalities are identified by endoscopic retrograde cholangiopancreatography. These include stricturing, dilatation, and beading of the biliary tract. Endoscopic sphincterotomy of the papilla of Vater may provide symptomatic relief for patients with papillary stenosis. opportunistic infections within the pancreas gland have been documented in both pre- and postmortem studies. However, the true incidence of pancreatitis related to infections is unknown. The presentation is similar to that of pancreatitis from other causes. A computerized tomogram of the abdomen is the investigation of choice. Tissue aspiration or biopsy of the pancreas is required to demonstrate the presence of an opportunistic infection. The management is usually supportive, as it is rare that a specific infection is identified and treated.- - - - - - - - - - ranking = 3keywords = tree (Clic here for more details about this article) |
8/24. Decision-making process in long term acute cholecystitis.OBJECTIVE: To demonstrate that the categorization of different therapeutic options is essential for the decision-making applied to clinical management. METHOD: This paper compares the usefulness of percutaneous echo-guided cholecystostomy as the first therapeutic option in acute long-term cholecystitis versus the exclusive surgical or clinical management. RESULT: We have analyzed the usefulness of different therapeutic options in a case of long term acute cholecystitis and we have obtained the following results: isolated intravenous antibiotic therapy (0.76), surgery (0.73) and echo-guided cholecystostomy (0.93). This last option has provided good clinical-radiological results. CONCLUSION: decision trees are a good methodological option as support of surgical and non surgical therapeutic procedures.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
9/24. Spontaneous cystic duct perforation associated with acalculous cholecystitis.Spontaneous perforation of the extrahepatic biliary tree is rare in adults. Although perforation of the hepatic, common hepatic, common bile, and cystic ducts has been reported, review of the English literature reveals only four cases of cystic duct perforation, each attributed to calculi. We herein report the first known case of spontaneous perforation of the cystic duct in the absence of biliary calculi.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
10/24. MRI of perforated gall bladder.Gall bladder perforation is a dreaded complication of acute cholecystitis that, if not diagnosed early in the course, might have a poor prognosis. Both CT and ultrasonography have been used until now extensively for the diagnosis of acute cholecystitis, but diagnosis of perforation is always difficult. Magnetic resonance, by its superior soft tissue resolution and multiplanar capability, is a better modality and should fare better than ultrasonography and CT, as demonstrated in our case. magnetic resonance imaging demonstrates the wall of the gall bladder and defects to a much better advantage and more convincingly. In addition, MR colangiopancreatography images demonstrate the biliary tree better than other modalities. We suggest that in the case of acute cholecystitis, if perforation is suspected and CT and ultrasonography are not conclusive, MR should be the modality of choice. It can be used as a first line of investigation; however, it might not be cost-effective.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
