Segmental Pancreatic Autotransplantation with Pancreatic Ductal Occlusion after Near Total or Total Pancreatic Resection for Chronic Pancreatitis: Results at 5− to 54-month Follow-up Evaluation

Reported are eight patients with idiopathic chronic pancreatitis and two patients with alcoholic pancreatitis who had near total distal pancreatectomy for disabling pain and underwent simultaneous segmental pancreatic autotransplantation of the body and tail of the gland to the femoral area in an attempt to prevent or delay the onset of diabetes. The median follow-up period was 31 months, and follow-up study in nine patients ranged from 24 to 54 months. Patency of the grafts was determined by angiography and selected percutaneous venous assays for insulin. Islet cell function was determined by oral glucose tolerance tests, intravenous (I.V.) glucose tolerance tests, and I.V. glucagon stimulation studies. Segmental autotransplantation was technically successful in eight patients, only one of whom required insulin (at 2 years after grafting). The other seven patients with technically successful grafts have remained insulin independent, including two patients who later underwent pyloric preserving pancrcatoduodenectomy for completion pancreatectomy. Variable pain relief was observed in patients who underwent near total pancreatectomy, but pain was unrelieved in those patients who underwent limited distal resection. Patients with idiopathic pancreatitis appear to have better pain relief and preservation of endocrine function than alcoholic patients. Segmental pancreatic autotransplantation prevents or delays the onset of diabetes mellitus and should be considered as an alternative for those patients who require extensive pancreatic resection for chronic pancreatitis.

Long-term results of pancreatic resection and segmental pancreastic autotransplantation for chronic pancreatitis

Thirteen patients who underwent extensive pancreatic resection and segmental autotransplantation and who have a median follow-up of 62 months are presented. Eleven patients had technically successful grafts. Three of six patients who underwent total pancreatectomy and three of five patients who underwent near-total resection remain insulin-independent. Those patients who require insulin require small doses and have stable diabetes. Pain has recurred in 7 of the 11 patients who underwent distal subtotal resection; 5 of them required pancreatoduodenectomy and completion pancreatectomy for pain relief. Because of the high rate of recurrence of pain after distal resection, we favor pancreatoduodenectomy as the initial procedure of choice. When distal near-total or total pancreatectomy is required, the addition of segmental autotransplantation offers definitive, although at times transient, benefits in glucose homeostasis compared with no transplantation.

Acute Relapsing Pancreatitis as a Complication of Papillary Stenosis After Endoscopic Sphincterotomy

Endoscopic sphincterotomy has proven to be a safe alternative to surgery for selected types of biliary disease. Despite a relatively low morbidity, postprocedure complications are well described. This report presents an experience with three patients in whom acute relapsing pancreatitis developed as a possible complication of papillary stenosis after endoscopic sphincterotomy. None of the patients had a previous history of elevations in serum amylase levels before endoscopic sphincterotomy. After procedure, pancreatitis and subsequently acute relapsing pancreatitis with documented stricture of the pancreatic duct orifice developed in all three patients. After surgical transduodenal sphincteroplasty, no new episodes of acute relapsing pancreatitis occurred.

Common bile duct calculi. 2. Nonsurgical therapy.

Several nonsurgical methods of therapy are available for treatment of retained common bile duct calculi. These include percutaneous extraction, endoscopic extraction, dissolution, and endoscopic sphincterotomy. The method chosen depends on location and size of calculi, size of sinus tract, patient age, surgical risks, and other factors. In most cases, procedures can be carried out safely and successfully with few or no complications.

Pancreatic pseudocyst with mediastinal extension and pleural effusion

Endoscopic retrograde cholangiopancreatography provides useful information in the diagnosis and management of patients with chronic pancreatitis. Knowledge of ductal anatomy is essential when planning operations for chronic pancreatitis. Demonstration of intraductal calculi, strictures, ductal ectasia, o r pseudocysts helps the surgeon decide which surgical approach is necessary for successful management. Our patient had chronic pancreatitis and pseudocyst with mediastinal extension and pleural effusion. Endoscopic pancreatography demonstrated an internal pancreatic fistula preoperatively.

Resective Operations for Biliary Carcinoma

Records of 25 consecutive patients who underwent resection for proximal bile duct tumor (3 extended right hepatic lobectomies, 6 left hepatic lobectomies, 16 skeletonization resections) and records of 21 patients who underwent pancreatoduodenectomy for distal bile duct carcinoma were reviewed to assess the value of resective therapy. The operative mortality rate for patients with resected proximal bile duct tumor was 4 per cent (0 per cent for liver resection) and that of distal bile duct tumor, 4.6 per cent. The 3- and 5-year actuarial survival rates for patients with proximal bile duct tumor were 44 per cent and 35 per cent, respectively; all except one patient eventually died of disease. Survival was better for patients who had curative resection (margins microscopically free of tumor). The 5-year actuarial survival rate for patients with distal bile duct carcinoma was 58±12 (SE) per cent, with patients who had negative nodes surviving longer than patients with positive nodes. When major hepatic resection and pancreatoduodenectomy can be performed in selected patients with low operative mortality, patients with bile duct carcinoma should be assessed by an experienced hepatobiliary multidisciplinary group before a decision is made in favor of palliative, endoscopic, or percutaneous techniques because surgical resection appears to offer the best possible long-term survival and probably the best quality of palliation.

Preoperative Evaluation of the Biliary Tract

When clinically suspected, obstructive jaundice presents the clinician with the problem of selecting the most suitable tests and determining the order in which they should be performed. Technology has provided a number of highly specific and quite expensive procedures. The studies most appropriately performed are ultrasonography, percutaneous transhepatic cholangiography, ERCP, flexible choledochoscopy, CT scan of the abdomen, HIDA scan, and intravenous cholangiography. The algorithmic approach is clinically helpful in this situation and is recommended as a useful guide.
