Management of major bile duct injuries after laparoscopic cholecystectomy.

BACKGROUND: The aim of this study was to analyze the presentation, characteristics, related investigation, and treatment results of major bile duct injuries (MBDI) after laparoscopic cholecystectomy (LC). METHODS: We performed a retrospective analysis of 27 patients who were treated between January 1995 and December 2002 for MBDI after LC at a single unit in a tertiary center. Major bile duct injury was defined according to the Strasberg classification. All patients underwent magnetic resonance cholangiography (MRC), percutaneous transhepatic cholangiography (PTC), or endoscopic retrograde cholangiopancreatography (ERCP) to delineate the biliary anatomy and assess the level of injury. On the basis of the cholangiographic findings, all patients underwent Roux-en-Y hepaticojejunostomy after a waiting period of 8-12 weeks. RESULTS: A total of 29 hepaticojejunostomies were performed in 27 patients. Seventeen patients (63%) presented with biliary fistula and ascites; 10 (27%) presented with obstructive jaundice. In 14 patients (52%) the MBDI was identified during the LC. Twenty patients (74%) had undergone one or more procedure before referral. Eight patients (30%) had E1, five patients (18.5%) had E2, nine patients (33%) had E3, and five patients (18.5%) had E4 injury. Two patients had early anastomotic stricture, for which redo hepaticojejunostomy with access loop was performed. CONCLUSIONS: Major bile duct injury after LC commonly presents with biliary fistula and ascites. High-injuries are common after LC. Hepaticojejunostomy repair yields excellent results in these cases.

Internal pancreatic fistulas with pancreatic ascites and pancreatic pleural effusions: recognition and management.

BACKGROUND: Internal pancreatic fistulas are well recognized complications of chronic pancreatitis. METHODS: Six patients with internal pancreatic fistulas were treated over a period of 5 years from 1995 to 1999. Four patients presented with ascites, one patient presented with ascites and bilateral pleural effusion and the sixth patient presented with left-sided pleural effusion. Five patients were chronic alcoholics and in one patient the cause of pancreatitis was not clear. Although the serum amylase was mildly elevated the levels of amylase in the aspirated fluid were consistently elevated (more than 800 Somogyi units/100 mL), along with the level of proteins (> or = 3 g/100 mL), and on this basis the diagnosis was made. Endoscopic retrograde cholangiopancreatography (ERCP) demonstrated pancreatic ductal disruption in four cases. Initial treatment was conservative, consisting of nasogastric aspiration, nil per oral, antisecretory drugs, repeated paracentesis or thoracocenthesis and total parenteral nutrition (TPN). In two patients naso-pancreatic drains (NPD) were placed across the disrupted pancreatic duct. RESULTS: In one patient conservative treatment with NPD was successful, and the remaining five patients required surgical intervention. There was no mortality. Two patients developed surgery-related complications that were successfully managed, but they required an extended hospital stay. CONCLUSION: Internal pancreatic fistulas should be treated initially non-operatively; if this is not effective, operative therapy should be considered without delay.

Role of selective intra-operative cholangiography during cholecystectomy.

BACKGROUND: The use of routine intra-operative cholangiography (IOC) remains controversial. This prospective study was carried out to determine whether to perform selective or routine IOC in patients undergoing cholecystectomy for gallstones. METHODS: All consecutive patients undergoing open cholecystectomy over a 16-month period were included in the present study. They were divided into two groups based on the absence (n = 79) or presence (n = 55) of indicators of choledocholithiasis. All patients were subjected to cholangiography. Each indicator, subsets of indicators and all indicators combined were evaluated for their ability to predict choledocholithiasis. RESULTS: There would be only two missed stones (1.5%) if selective cholangiography was to be practised. Intra-operative cholangiography had a positive predictive value of 100%. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of all the indicators combined were 93.5%, 84.6%, 74.5%, 97.5% and 88.0%, respectively. The best indicators in each subset were jaundice, common bile duct diameter as assessed by ultrasonography, and a palpable stone during surgery with NPV of 82.7%, 91.1% and 96.8%, respectively. CONCLUSION: Routine IOC during cholecystectomy is not essential for the prevention of retained stones. A combination of the various indicators of choledocholithiasis can be used to select patients for cholangiography.

Necrotizing fascitis after injection sclerotherapy for hemorrhoids: report of a case.

A case report of a patient who underwent submucosal injection sclerotherapy for hemorrhoids is presented. Subsequently developed necrotizing fascitis of the anorectum, perianal region, and scrotum necessitated emergency debridement and defunctioning colostomy. Postoperatively, the patient developed septicemia and renal failure requiring an extended hospital stay. Restoration of bowel continuity was done after three months. A brief review of known complications of this technique was made. It would appear that necrotizing fascitis can be added to this list.

Diagnostic and therapeutic approaches to carotid body tumours: report of three cases and review of the literature.

BACKGROUND: Carotid body tumour is a rare neoplasm of the carotid body. Three cases of carotid body tumour presenting as a painless progressive mass in the neck region are reported here. A review of the relevant literature regarding carotid body tumours is also presented. METHODS: Angiographic features were diagnostic of carotid body tumour and complete surgical excision was done. RESULTS: There was no mortality and minimum morbidity. There were no malignant tumours. All three patients belong to the high-altitude area of Himachal Pradesh. CONCLUSIONS: A high degree of clinical suspicion of upper posterior triangle neck masses and an accurate diagnostic work-up are needed for operative planning.

Pseudoaneurysm of the cystic artery: a rare cause of hemobilia.

Aneurysms are a rare cause of hemobilia, and usually involved are branches of the hepatic and gastro-duodenal arteries. A case of a patient with hemobilia secondary to a pseudoaneurysm of the cystic artery is presented. Fewer than 10 cases have been reported in the literature, and in all of them the condition was associated with inflammation of the gall bladder, as in our case. Selective hepatic angiography is the procedure of choice for diagnosis. Upper gastrointestinal endoscopy with side-viewing scopy can demonstrate bleeding from papilla. Color-Doppler ultrasonography also may prove to be useful in equivocal cases. Cholecystectomy and ligation of cystic artery with proximal control of the hepatic artery was done at laparotomy after diagnosis was made.

Multiple endocrine neoplasia type-1.

A 38-year-old man with multiple endocrine neoplasia type-1 (Wermer's syndrome) is described. The patient had refractory duodenal ulcers and raised basal acid output (55 mmol/hour) and fasting serum gastrin (1190 pg/ml). Abdominal CT scan revealed mass lesions (gastrinomas) in the head of the pancreas. He also had persistent hypercalcemia, hypophosphatemia, right ureteric calculi, increased urinary calcium and phosphorus and enlarged parathyroids on ultrasound and CT of the neck. Parathormone level was raised, but the pituitary gland was normal on CT scan of the head. The patient was managed initially with histamine H2-blockers, omeprazole and parathyroidectomy; enucleation of the tumor masses in the pancreas was done subsequently.

Nifedipine and surgical removal of phaeochromocytoma.

The management of five patients with phaeochromocytoma undergoing surgical removal is described. Pre-operative preparation with phenoxybenzamine and nifedipine for 7 days before surgery prevented excessive fluctuations in cardiovascular parameters in the peri-operative period and resulted in an uneventful recovery.

"Bypass arthritis" after gastroileostomy.

We describe a patient who underwent inadvertent gastroileostomy, and subsequently developed malabsorption, granulomatous hepatitis, arthritis, and reactivation of tuberculosis accompanied by circulating immune complexes and lowered C1q. Surgical correction resulted in marked improvement, with disappearance of arthritis, return to normal of complement levels, and absence of demonstrable circulating immune complexes. Arthritis has not been documented in the spectrum of abnormalities described after gastroileostomy.
