Is bactibilia a predictor of poor outcome of pancreaticoduodenectomy?

BACKGROUND: Although bile infection has been proposed to increase infective complications following pancreaticoduodenectomy, its association with infective complications and non-infective complications like pancreatic fistula is still controversial. METHODS: Seventy-six patients who had undergone pancreaticoduodenectomy between July 2007 and December 2008 were included in a prospective database and their data analyzed. In all patients intraoperative bile from the bile duct was cultured. Preoperative, intra-operative, and post-operative variables were recorded and analyzed. RESULTS: Bile culture showed positive growth in 35 patients and negative growth in 41. Twenty patients in the positive group underwent ERCP and stenting. The patients with a positive bile culture had a higher incidence of infective complications including intra-abdominal abscess (n=8), wound infection (n=27), bacteremia (n=10), and renal insufficiency (n=9). There was no increase in the rate of non-infective complications of pancreaticoduodenectomy including pancreatic fistula (n=7), delayed gastric emptying (n=9), and post-operative hemorrhage (n=3). The hospital stay was significantly prolonged in the patients with a positive bile culture (P=0.0002). CONCLUSIONS: Pre-operative biliary drainage is significantly associated with bile infection, and bile infection increases the overall rates of infective complications and renal insufficiency. Because of the high incidence of complications is associated with infected bile, routine intra-operative bile culture is recommended in patients undergoing pancreaticoduodenectomy. Pre-operative prophylaxis is dependent on sensitivity of cases to perioperative antibiotics and intra-operative bile culture report. Because of its significant association with infected bile, biliary stenting should be used in strictly selected cases.

Haemosuccus pancreaticus: diagnostic and therapeutic challenges.

BACKGROUND: Haemosuccus pancreaticus (HP) is a rare cause of upper gastrointestinal bleeding. The objective of our study was to highlight the challenges in the diagnosis and management of HP. METHODS: The records of 31 patients with HP diagnosed between January 1997 and June 2008 were reviewed retrospectively. RESULTS: Mean patient age was 34 years (11-55 years). Twelve patients had chronic alcoholic pancreatitis, 16 had tropical pancreatitis, two had acute pancreatitis and one had idiopathic pancreatitis. Selective arterial embolization was attempted in 22 of 26 (84%) patients and was successful in 11 of the 22 (50%). Twenty of 31 (64%) patients required surgery to control bleeding after the failure of arterial embolization in 11 and in an emergent setting in nine patients. Procedures included distal pancreatectomy and splenectomy, central pancreatectomy, intracystic ligation of the blood vessel, and aneurysmal ligation and bypass graft in 11, two, six and one patients, respectively. There were no deaths. Length of follow-up ranged from 6 months to 10 years. CONCLUSIONS: Upper gastrointestinal bleeding in a patient with a history of chronic pancreatitis could be caused by HP. Diagnosis is based on investigations that should be performed in all patients, preferably during a period of active bleeding. These include upper digestive endoscopy, contrast-enhanced computed tomography (CECT) and selective arteriography of the coeliac trunk and superior mesenteric artery. Contrast-enhanced CT had a high positive yield comparable with that of selective angiography in our series. Therapeutic options consist of selective embolization and surgery. Endovascular treatment can control unstable haemodynamics and can be sufficient in some cases. However, in patients with persistent unstable haemodynamics, recurrent bleeding or failed embolization, surgery is required.

Pancreaticogastrostomy for pancreatic ascites.

BACKGROUND/AIMS: Management of pancreatic ascites is challenging. The aim of the present study was to study the role of pancreaticogastrostomy in management of pancreatic ascites. METHODOLOGY: Retrospective analysis of twelve operated cases with pancreatic ascites following failed conservative and endoscopic treatment was done for its outcome in terms of morbidity and a successful outcome. Patient data, imaging information and surgical procedure were noted. RESULTS: Four of the 12 patients with leak from the dilated main pancreatic duct had longitudinal pancreaticogastrostomy. The gross edematous jejunum and a shortened mesentery due to sub-acute peritonitis necessitated this surgery. None had recurrence of ascites. Steatorrhea was distinctly absent. None had deterioration of endocrine function. CONCLUSIONS: Longitudinal pancreaticogastrostomy is a viable option in patients with pancreatic ascites and dilated main pancreatic duct especially in those with a shortened mesentery and an edematous small bowel.

Acute portal vein thrombosis and massive necrosis of the liver. An unusual complication after stenting for chronic pancreatitis.

CONTEXT: ERCP can provide information which is invaluable in managing chronic pancreatitis but it is associated with infrequent, although significant, complications and rare mortality. The complications uniquely associated with diagnostic ERCP include pancreatitis and sepsis (primary cholangitis). CASE REPORT: A 32-year-old man presented with severe upper abdominal pain radiating to the back, associated with vomiting and abdominal distension. The patient was diagnosed as having had chronic calcific pancreatitis recently and had undergone ERCP with pancreatic duct stenting elsewhere. Two days after the procedure, the patient developed severe abdominal pain, vomiting and abdominal distention, and patient was referred to our hospital 7 days after the procedure. Investigation revealed massive liver necrosis and portal vein thrombosis. This patient had a life-threatening complication following pancreatic duct stenting for chronic pancreatitis and was managed medically. CONCLUSION: Therapeutic pancreatic endoscopy procedures are technically demanding and should be restricted to high volume centers. There is a continuing need for evaluation and comparison with alternative strategies. In a good surgical candidate, it is better to avoid stenting.

Large cell neuroendocrine carcinoma of the ampulla of Vater.

BACKGROUND: Neuroendocrine tumors of the ampulla of Vater are extremely rare, and few cases of large cell neuroendocrine carcinoma (LCNEC) of the ampulla have been reported. METHODS: A 48-year-old male with obstructive jaundice was admitted to our hospital. On examination the patient was found to have a periampullary growth and subsequently underwent the Whipple's procedure. RESULTS: Histopathological examination and immuno-histochemistry revealed features of LCNEC of the ampulla of Vater. The patient developed multiple liver metastases 6 months after Whipple's procedure. CONCLUSION: LCNEC of the ampulla of Vater is rare and highly aggressive, with a dismal prognosis.
