Clear cell carcinoid tumor of the distal common bile duct

BACKGROUND: Carcinoid tumors rarely arise in the extrahepatic bile duct and can be difficult to distinguish from carcinoma. There are no reports of clear cell carcinoid (CCC) tumors in the distal bile duct (DBD) to the best of our knowledge. Herein, we report a CCC tumor in the DBD and review the literature concerning extrahepatic bile duct carcinoid tumors. CASE PRESENTATION: A 73-old man presented with fever and occult obstructive jaundice. Ultrasonography, computed tomography (CT) and magnetic resonance cholangiopancreaticography (MRCP) demonstrated a nodular tumor projection in the DBD without regional lymph node swelling. Under suspicion of carcinoma, we resected the head of the pancreas along with 2(nd )portion duodenectomy and a lymph node dissection. The surgical specimen showed a golden yellow polypoid tumor in the DBD (0.8 × 0.6 × 0.5 cm in size). The lesion was composed of clear polygonal cells arranged in nests and a trabecular pattern. The tumor invaded through the wall into the fibromuscular layer. Immunohistochemical stains showed that neoplastic cells were positive for neuron-specific enolase (NSE), chromogranin A, synaptophysin, and pancreatic polypeptide and negative for inhibin, keratin, CD56, serotonin, gastrin and somatostatin. The postoperative course was uneventful and he is living well without relapse 12 months after surgery. CONCLUSION: Given the preoperative difficulty in differentiating carcinoid from carcinoma, the pancreaticoduodenectomy is an appropriate treatment choice for carcinoid tumors located within the intra-pancreatic bile duct

Post-cholecystectomy benign biliary stricture with portal hypertension: is a portosystemic shunt before hepaticojejunostomy necessary?

BACKGROUND: Portal hypertension develops in 15-20% of patients with benign bile duct stricture. Hepaticojejunostomy in such patients is associated with considerable morbidity and mortality. Preliminary portosystemic shunting has been suggested to reduce intra-operative bleeding. We present our experience without preliminary shunting in such patients. PATIENTS AND METHODS: Fourteen consecutive cases of biliary stricture with portal hypertension over a 13-year period (1989-2001) were retrospectively analysed. RESULTS: Thirteen patients were operated upon. One patient had a preliminary portosystemic shunt. In another patient, shunt was attempted. One stage hepaticojejunostomy was possible in 11 patients. There were no intra-operative deaths. Nine of the 13 survived and were available for follow-up. One patient had cholangitis. Another had jaundice related both to chronic liver disease and a strictured hepaticojejunostomy. The remaining 7 patients are asymptomatic and anicteric although alkaline phosphatase levels remain elevated in 5 of them. CONCLUSIONS: Hepaticojejunostomy without preliminary portosystemic shunting is possible in patients with portal hypertension and benign biliary stricture with acceptable morbidity and mortality rates

Collateral Artery Aneurysm: A Unique Presentation of Thoracic Outlet Syndrome

AbstractAneurysms of collateral arteries are unusual. A case of transverse cervical artery aneurysm as the sole presentation of vascular thoracic outlet syndrome is presented and the relevant literature reviewed

Surgical intervention for anorectal fistula

BACKGROUND: Surgery for anorectal fistula may result in recurrence, or impairment of continence. The ideal treatment for anorectal fistulae should be associated with low recurrence rates, minimal incontinence and good quality of life. OBJECTIVE: To assess the efficacy and morbidity of operative procedures for chronic anal fistula, primary outcomes being recurrence and incontinence. CRITERIA FOR CONSIDERING STUDIES FOR THIS REVIEW: The following databases were searched: EMBASE (Webspirs 5.1, Silver Platter version 2.0, 1950-2009); Medline (Webspirs 5.1, Silver Platter version 2.0, 1950-2009); The Cochrane Central Register of Controlled Trials (2009 issue 4)and the IndMed ( Indian Medline, www.indmed.nic.in) database. We restricted our search to the English literature. The Indian Journal of Surgery was electronically searched (issues between 2003 and vol 71, Oct 2009). We also searched all primary trial registers (Indian, Australian, Chinese, WHO, ISRCTN and American). SELECTION CRITERIA: Randomised controlled trials comparing operative procedures for anorectal fistulae were considered. Non randomised trials and cohort studies were examined where data on recurrence and function were available. DATA COLLECTION AND ANALYSIS: Two reviewers (TJ and BP) independently selected the trials for inclusion in the review. Disagreements were solved by discussion. Where disagreement persisted and published results made data extraction difficult, we obtained clarification from the authors. REVMAN 5 was used for statistical analysis. Quality of the trials were assessed and allowances made for subgroup analysis and prevention of publication bias, using funnel plots if needed. MAIN RESULTS: Ten randomized controlled trials were available for analysis. The quality of included studies was adequate, though in some trials the numbers were small and they were inadequately powered for equivalence or to detect significant differences. Comparisons were made between various modalities of treatments. There were no significant difference in recurrence rates or incontinence rates in any of the studied comparisons except in the case of advancement flaps. There were more recurrences in the glue plus flap group, a significant difference that favoured the flap only technique. It was also noted that Fibrin glue and advancement flap procedures report low incontinence rates. In the review of literature of non-randomized trials, most trials on fibrin glue indicate good healing in simple fistulae with low incontinence rates. AUTHORS' CONCLUSIONS: There are very few randomized controlled trials comparing the various modalities of surgery for fistula in ano. While post operative pain, time to healing and discharge from hospital affect quality of life, recurrence and incontinence are the most important. As it turns out, there seems to be no major difference between the various techniques used as far as recurrence rates are concerned
