The surgical management of chronic pancreatitis: duodenum-preserving pancreatectomy.

Duodenum-preserving pancreas resection for chronic pancreatitis results in a subtotal resection of the pancreatic head. Of 488 patients suffering from chronic pancreatitis with an inflammatory mass in the head, 48% had a common bile duct stenosis in the ERCP, 63% had a pancreatic main duct stenosis, 25% had a duodenum stenosis, and 17% showed vascular obstruction--mainly compression or occlusion of the portal vein. Hospital mortality after duodenum-preserving head resection was 0.9%. In the late follow-up, 88% of patients were free of pain and 60% were professionally rehabilitated. The incidence of diabetes mellitus in the late follow-up was 14%; however, 6% of the patients had a lasting improvement of endocrine function. Late mortality after a median follow-up of 6 years (1-22 years after surgical treatment) was 9%. Only 10% of the patients needed further hospitalization due to recurrent attacks of acute pancreatitis. Duodenum-preserving head resection should be the surgical procedure of choice in chronic pancreatitis with an inflammatory mass in the head of the pancreas and in cases with pancreas divisum after failure of medical and interventional treatment. Duodenum-preserving total pancreatectomy is a last-resort surgical treatment after failure of left resection for pain in chronic pancreatitis.

The absorption of vitamin B12 after subtotal pancreatectomy in the rat.

Subtotal pancreatectomy in the rat was performed by a new method. Except for a small remnant along the splenal hilus, the gland was completely removed. Exocrine pancreatic insufficiency was confirmed by fat and nitrogen malabsorption. A moderate diabetes mellitus was seen. Insulin substitution or diet restriction was unnecessary. The absorption of vitamin B12 after oral administration of 10 ng 57CoB12 was 5.0 +/- 0.2 (ng 57CoB12 +/- S.E.M.) in unoperated rats and 5.1 +/- 0.1 in pancreatectomized rats (p greater than 0.5). Pancreatic extract (PE) (100 mg) increased the absorption of 57CoB12 in unoperated rats (p less than 0.01), but not in pancreatectomized rats (p greater than 0.2). PE (300 mg) reduced the absorption in unoperated rats (p less than 0.01). The results indicate that an optimal amount of pancreatic secretion may stimulate the absorption of vitamin B12.

Neonatal hypoglycemia resulting from islet cell adenomatosis. Successful treatment with total pancreatectomy.

A female infant developed apneic spells due to hypoglycemia at 73 hours of life. It was impossible to maintain the blood glucose level despite continuous intravenously given dextrose, cortisone, diazoxide, and a low-leucine diet. A subtotal pancreatectomy was performed but there was no evidence of islet cell adenoma. On second laparotomy, the head of the pancreas was removed, and on microscopic examination, islet cell adenomatosis was found. A good clinical recovery followed. Follow-up at age 3 years and 4 months shows apparently normal mental and physical development.

Pancreatic ascites: management by caudal pancreatectomy and side-to-side pancreaticojejunostomy.

A patient with pancreatic ascites is presented who had neither a pseudocyst nor demonstrable pancreatic duct disruption, despite the presence of both calculi and strictures in a dilated duct of Wirsung. Concurrently, the patient exhibited intractable abdominal pain characteristic of end-stage chronic alcoholic pancreatitis. The pancreatic ascites responded only briefly to nonoperative management with hyperalimentation. Side-to-side pancreticojejunostomy with caudal pancreatectomy relieved the patient of both pain and ascites, suggesting that this more direct approach may be worthy of consideration in patients with similar findings.

[Use of lanreotide in the prevention of pancreatic fistula after cephalic duodeno-pancreatectomy. Preliminary study].

STUDY AIM: Dehiscence of pancreatic anastomosis is the main complication after pancreatoduodenectomy. The efficacy of somatostatin analogue to prevent complications after pancreatic resections is at present well-established by several randomized trials. The aim of this preliminary prospective study was to assess the role of lanreotide (a long acting somatostatin analogue) in this field. PATIENTS AND METHOD: Forty patients with pancreatic head tumour have been included in a prospective study. Criteria for pancreatic fistula were: high concentration of amylase in the drainage fluid (> 3 times that in the serum), or intra-abdominal fluid collection adjacent to the pancreatic anastomosis, or reoperation (or postmortem verification) showing an anastomotic dehiscence. The patients received 12 h before the operation 30 mg of lanreotide intramuscularly. RESULTS: Of the 40 patients included prospectively, 34 underwent a pancreatic resection. Parenchyma of pancreatic remnant was crumbly in 28 cases. Six patients experienced a pancreatic fistula (17.6%) which healed in all cases. CONCLUSION: This preliminary study shows clearly the feasibility of a long acting somatostatin analogue (lanreotide) to prevent pancreatic fistula after pancreatectomy. This agent appears simple to use and its efficacy needs obviously to be assessed by randomized trials.

Duodenectomy without pancreatectomy for extensive benign villous adenoma of the duodenum.

Villous adenomas of the duodenum are uncommon, but two have been treated recently in Blenheim. One of these was an extensive benign tumour involving most of the second part of the duodenum but causing no biliary tract obstruction. It was treated by pyloric sphincter-sparing duodenectomy without pancreatectomy, with repair by Roux loop to the bile and pancreatic ducts and proximal duodenum. This procedure does not appear to have been described previously.

Diabetes related genetics and outcomes after total pancreatectomy with islet autotransplantation.

CONTEXT: Approximately 20% of patients with chronic pancreatitis achieve insulin independence one year after total pancreatectomy with islet autotransplantation (TPIAT), an outcome associated with younger age and lower pre-transplant HbA1c. The contribution of diabetes-related genetics to TPIAT outcomes is unknown. Genetic risk scores (GRS) are associated with C-peptide levels in type 1 (T1D) and type 2 (T2D) diabetes. OBJECTIVE: To evaluate whether T1D and T2D GRS and partitioned metabolic polygenic scores (PGS) are associated with diabetes before TPIAT and metabolic outcomes one year after transplant. METHODS: We genotyped 318 patients with chronic pancreatitis undergoing TPIAT in the multicenter "Advancing Treatment for Pancreatitis: A Prospective Observational Study of TPIAT" using a global screening array. Regression models assessed associations of T1D- and T2D-GRS and metabolic PGS with diabetes outcomes one year after TPIAT. RESULTS: Participants were 29±17 years old, 61% female, 84% non-Hispanic White, and 13% had diabetes prior to transplant. T2D-GRS was higher among those with pre-TPIAT diabetes (-0.6±0.3 versus -0.8±0.2, p=0.003) and was associated with higher pre-transplant HbA1c (β=0.19 % per 1-SD [95% CI:0.04, 0.33], p = 0.011). Adjusted for genotype-derived ancestry and islet equivalents/kg, the beta-cell PGS was associated with higher insulin dose (β=0.05 units/kg/day per 1-SD, [95%CI:0.01, 0.09], p=0.016) and higher insulin dose adjusted A1c (IDAA1c) (β=0.34[95%CI:0.03, 0.67], p=0.029) 1-year post-transplant. The lipodystrophy PGS was associated with higher IDAA1c (β=0.38 [95%CI:0.06, 0.69], p=0.019) and lower fasting C-peptide (β=-0.09 [95%CI:-0.18, 0], p=0.041) at 1 year. CONCLUSIONS: T2D genetic risk is associated with diabetes prior to TPIAT, and beta cell and lipodystrophy PGS are associated with post-TPIAT diabetes outcomes. Diabetes-related genetics may influence transplantation outcomes and inform metabolic heterogeneity.

Survival and rehabilitation after total pancreatectomy. A follow-up of 36 patients.

Thirty-six totally depancreatectomized patients were followed up for 4-124 months. Pancreatectomy had been performed because of fulminant pancreatitis (in 10), chronic hyperalgic otherwise untractable pancreatitis (in 7), exocrine carcinoma of the pancreas (in 16), cystadenocarcinoma of the pancreas (in 2) and insulinoma (in 1). The longest survival duration was in chronic pancreatitis patients: 57 +/- 17 months. A normal socio-professional reinsertion was obtained in 16 patients, mainly those with non-malignant pancreotopathies. At the end of the survey, ten of the carcinoma patients had died, versus none in the other groups. Diabetes mellitus was characterized by the absence of ketonuria, and the frequent occurrence of hypoglycemia (in 15 patients) and infection (in 6). Malabsorption caused osteomalacia in one patient.

The influence of preoperative jaundice, biliary drainage and age on postoperative morbidity and mortality after pancreatoduodenectomy and total pancreatectomy.

Details are given of the postoperative course of 56 patients after pancreatoduodenectomy, and 11 after total pancreatectomy. The main indication was adenocarcinoma (56 cases). The most serious complication was leakage from the pancreatojejunostomy, which occurred in nine patients and was fatal in seven of these (10%). This was the only cause of death in the group. The observed mortality was appreciably higher (38%) in the 13 patients aged over 70 years. Contrary to recent reports, jaundice was not found to influence postoperative mortality adversely, nor was preoperative biliary drainage found to reduce mortality.
