In 128 patients with severe chronic pancreatitis and inflammatory enlargement of the head of the pancreas, a duodenum-preserving resection of the pancreatic head was performed. Median post-operative hospitalization was 15.5 days, and the frequency of reoperation was 5.5%. One patient died during the early post-operative phase, and hospital mortality amounted to 0.8%. After a median follow-up period of 3.6 years (range of 7 months to 16 years), six of 127 patients died (late mortality of 4.7%). Seventy-seven per cent of the patients were completely free of abdominal pain, 67% returned to their former occupations. During the late follow-up period, the glucose metabolism was unchanged in 80.7% of the patients, in 13.7% it deteriorated, and in 5.5% it improved permanently; 80% of the patients experienced a marked increase in weight averaging 8.7 kg. Compared with the Whipple procedure, the duodenum-preserving resection of the head of the pancreas spares the patient with chronic pancreatitis a gastrectomy, duodenectomy, and resection of the extrahepatic biliary ducts. In terms of a subtotal resection, the limited operative intervention at the head of the pancreas and the preservation of the duodenum explain the low early and late postoperative morbidity and mortality.

Necrosectomy with postoperative continuous local lavage was performed in a prospective study involving 95 patients with necrotizing pancreatitis. In the same period 567 patients with oedematous-interstitial pancreatitis were treated non-operatively with a hospital mortality rate of 0.7 per cent. In patients with necrotizing pancreatitis the median Ranson criteria score was 4.5 points; operation was required at a median of 7 days after the onset of symptoms because of non-response to conservative treatment. In all, 59 per cent of the patients (56 out of 95) developed extended intrapancreatic parenchymal necrosis, 70 per cent had ascites, and 66 per cent had intra- and extrapancreatic necrosis; 42 per cent of the patients had bacterial infection of the necrotic tissue. For lavage a median of 8 l/24 h of fluid were instilled postoperatively for 25 days (median). The lavage fluid showed high levels of immunoreactive trypsin, phospholipase A2, and endotoxin in the early postoperative period. Hospital mortality rate was 8.4 per cent. Necrosectomy and continuous postoperative lavage can achieve high survival rates in patients with necrotizing pancreatitis. Postoperative local lavage allows the continuous non-operative evacuation of biologically active compounds and devitalized tissue, and avoids damage to remaining vital exocrine and endocrine pancreatic tissue.

Early and late results from 298 patients with chronic pancreatitis who were surgically treated by means of duodenum-preserving pancreatic head resection (DPPHR) were prospectively analyzed. The aim of this operative procedure is to treat complications of chronic pancreatitis caused by inflammatory enlargement of the pancreatic head by decompressing the common bile duct, the pancreatic duct, the duodenum, and the retropancreatic intestinal vessels. End points of the study were early and late postoperative outcome. The follow-up period ranged from 1 to 22 years with a median follow-up of 6 years. In-hospital mortality was 1%, postoperative morbidity was 28.5%, and the rate of repeat laparotomy was 5.7%. Diabetes mellitus developed early in the postoperative period in six patients (2%). After a median follow-up of 6 years, late mortality was 8.9%. In the late follow-up period 88% of our patients were completely free of pain or had infrequent episodes and 63% were able to return to work. DPPHR might be considered as an alternative surgical technique in the treatment of chronic pancreatitis if the dominant lesion is in the pancreatic head.
