Surgical indications for chronic pancreatitis can be schematically separated into five main groups: pain, effects of fibrosis on adjacent organs, the consequences of main pancreatic duct rupture above an obstruction, and suspected cancer. Finally surgery is also indicated in patients who cannot undergo endoscopic procedures (no accessible papilla) or who have too recently undergone this procedure. Surgical procedures include derivation (pancreatic, cystic, biliary) or mixed procedures combining derivation/resection or pancreatic resection. Finally splanchnicectomy can be discussed. Whatever the indication, surgical treatment must meet several goals: the approach to surgery must be multidisciplinary, surgery must be associated with low morbidity and mortality, preserve as much endocrine function as possible, improve quality of life, and be evaluated in the long term, as well as prospectively if possible. We clarify some important points about the management of patients with chronic pancreatitis before discussing the various treatments in detail.

Obstructive jaundice is uncommon in patients with hepatocellular carcinoma. It can be due to compression of the common bile duct by the liver tumor or by enlarged lymph node metastases in the porta hepatis. Obstructive jaundice can also be due to direct extension of hepatocellular carcinoma into the bile ducts with or without a detectable primary hepatic tumor. These particular hepatocellular carcinoma have been termed "icteric type hepatoma" by Lin et al. in 1975, who emphasized their poor prognosis. We report a similar case of endobiliary hepatoma without a detectable intraparenchymal hepatic tumor in a seventy year-old man. This case is unusual because of its positive evolution and late recurrence.

Unlabelled: Colonic pseudolipomatosis is a rare and benign condition. It is not well known by gastroenterologists and its pathogenesis is still unclear., Methods: All cases of colonic pseudolipomatosis seen between February 2002 and June 2004 at the Amiens Universisty Hospital were identified and analyzed., Results: During this period, 2099 colonoscopies were performed and 9 cases of colonic pseudolipomatosis were diagnosed (0.4%). Patients were all males aged from 41 to 67 (median age 52 years). They consulted for rectal bleeding (two patients), diarrhea (two patients) or abdominal pain (two patients). In three patients, colonic pseudolipomatosis was a fortuitous discovery during colonoscopy for polyp surveillance. The lesions presented as whitish and yellowish slightly elevated plaques ranging in size from a few millimeters to 4 cm. They extended over a two to 20 cm-long area, located in the right (two patients), transverse (four patients) or left colon (three patients). Microscopic examination showed empty spaces in the lamina propria measuring from 50 to 600 microm. They were negative for anti-CD31, CD34 and PS100 antibodies at immunohistochemistry and negative for Sudan black in three cases. The ultrastructural study showed in two cases round spaces containing small fibrillary protein-like deposits that might be lymph., Conclusion: Colonic pseudolipomatosis is rare. Its pathogenesis is not well-known but could be due to gas invasion or extravasation of lymph into lamina propria, maybe induced by mucosal lesions related to barotrauma or certain colonoscope cleaning solutions.

Objectives: Endoscopy offers an alternative to surgery for the treatment of ductal complications in patients with chronic pancreatitis. The aim of this study was to evaluate the efficacy of endoscopic treatment on pain, cholestasis and pseudocysts in these patients., Patients and Methods: Thirty-nine patients (37 M, 2 F, mean age 44), were included in the study. All patients had at least one of the following criteria demonstrated by imaging tests: dilatation of the main pancreatic duct (MPD) with or without stricture (N = 13), bile duct stricture (N = 12), or pancreatic pseudocyst (N = 14) with pancreatic duct stricture (N = 11) or biliary stricture (N = 3). Pancreatic or biliary sphincterotomy, insertion of pancreatic or biliary stent, pseudocyst drainage with stent placement were performed according to ductal abnormalities. Patients were evaluated early and followed up during the stenting period, and after stent removal., Results: Patients underwent a median of 3.5 endoscopic procedures with an interval of 2.2 months between 2 stenting sessions. A pancreatic or biliary stent was inserted in 25 patients with ductal abnormalities and in 11 patients with pseudocysts. Endoscopic pseudocyst drainage was performed in 6 cases. The mean stenting time was 6 months (range: 3-21). Mean follow-up after stent removal was 9.7 (2-48) months. Complications of endoscopic treatment were encountered in 7% of patients with no deaths. Pain relief was achieved after the first endoscopic procedure and during the overall stenting period in all patients. Recurrence of pain was observed after stent removal in 5/11 patients, requiring surgery in 4. Cholestasis decreased and biochemical values normalized within one month after biliary stenting. Recurrence of cholestasis was observed early after stent removal in 4/9 patients who required complementary surgical treatment. No recurrence of pancreatic pseudocyst was observed after endoscopic drainage and stent removal during the follow-up period., Conclusions: Endoscopic treatment of pain from pancreatic pseudocysts or ductal strictures is effective in the short-term and in the period of ductal stenting. However, the optimal duration of the latter remains to be determined.

Numerous infectious agents may induce acute pancreatitis. We report 6 cases of Salmonella-associated acute pancreatitis. Pathogenesis of this type of pancreatitis is related to multiple factors that may coexist in the same patient. The typical clinical picture consists in epigastric pain, nausea, vomiting, diarrhoea and fever. Imaging techniques often disclose minimal changes such as moderate swelling of a part or of the totality of pancreas. As outcome is usually good, conservative treatment and antibiotics may be sufficient to ensure recovery.
