We studied the early time-course of gastrin, somatostatin, and gut growth responses to 70% resection of mid-small intestine. Serum and antral gastrin increased by the 2nd day following resection and remained elevated for the 10-day period of study. Antral somatostatin remained unchanged, suggesting that the increase in gastrin was a selective antral response. Duodenum and ileum showed marked growth stimulation, which was progressive with time, and earlier and greater in duodenum. In contrast, gastric growth was unaffected. Thus, early responses to resection are characterized by specificity of gastrin, somatostatin, and growth effects.

Given an indication for surgery in patients with chronic pancreatitis, such as distal common bile duct obstruction, duodenal stenosis, or dilated pancreatic duct with stones and congestion, the surgeon must decide the type of operation to perform. A duodenopancreatectomy, the Whipple procedure, is widely considered to be the gold standard. It is highly effective in relieving pain and eliminating the structural abnormalities noted above. Duodenum-preserving resection of the head of the pancreas (DPRHP) seems to be an attractive alternative to pancreaticoduodenectomy (PD) in the treatment of chronic pancreatitis. In a clinical prospective randomized trial the efficiency of both operative methods was investigated. Between 7/1987 and 12/1993 43 patients were randomly assigned to undergo either a Whipple procedure (n = 21) or DPRHP (n = 22). Data on postoperative course, mortality, and postoperative morbidity were compiled. As concerns long-term results, postoperative hormonal status (insulin, neurotensin, cholecystokinin, gastrin) was checked, basal and stimulated with a standardized meal, using standard hormonal assay kits. All patients with PD survived, whereas one with DPRHP died from peritonitis. Patients with DPRHP had a significant more rapid convalescence (16.5 vs. 21.7 days). The range for postoperative follow-up is from 36 months to 5.5 years. In the DPRHP group 18 patients are in good condition. Two had diabetes and one developed carcinoma. In the PD group one died from hepatic coma, 14 are in good condition and 6 developed diabetes. All gained body weight with an average of 6.4 vs. 4.9 kg, DPRHP vs. PD. A difference between DPRHP and PD was obvious for the postoperative hormonal status. Results are satisfactory in both groups. For patients with DPRHP however, we see a quicker convalescence and a significant benefit as concerns postoperative hormonal status.

Carcinoid Tumours are classified as Neuro-endocrine tumours. Commonly known ulcerogenic neuro-endocrine tumour is Gastrinoma of the Pancreas and Duodenum.It secretes hormone Gastrin which causes hyperplasia of the gastric parietal cells with excessive secretion of hydrochloric acid resulting in multiple ulcerations in the stomach, duodenum and upper jejunum. Carcinoid tumours is not known to cause peptic ulceration.
