Surgical management of acute pancreatitis.

Acute pancreatitis is a formidable problem that infrequently necessitates surgical intervention. Indications for operation may be divided into four main categories: (1) uncertain diagnosis, (2) deteriorating condition, (3) biliary pancreatitis, and (4) pancreatic abscess. One of the most important contributions concerning acute pancreatitis has been the development of predictive criteria that allow quantitation of the severity of disease and precise comparison of various reported series. During a 2-year period, 222 patients with acute pancreatitis were seen at our institution, and 62 of these patients (28%) underwent operation. Biliary pancreatitis accounted for 63% of our cases. The overall mortality of 24% was directly related to the severity of the pancreatitis. Cholecystectomy, during the same hospital admission, is advised for treatment of biliary pancreatitis.

Surgical treatment of recurrent peptic ulcer disease.

One hundred twenty patients in whom recurrent peptic ulcer developed after various surgical procedures for primary duodenal ulcer were operated on at the Mayo Clinic between 1970 and 1975. The postoperative mortality rate was 3.3% for all cases, 0.9% for elective cases, and 23% for the 13 patients who required emergency surgical care. The mean hospital stay was 13 days, and postoperative complications developed in 25 patients (20%). Approximately 70% of the patients had excellent or good results, whereas the rest had significant postoperative sequelae, including 8.4% (9 patients) in whom rerecurrent ulceration developed. When remedial surgery for recurrent ulcer consisted of vagotomy and distal subtotal gastrectomy (35 patients) after previous vagotomy and drainage procedure (21 patients), subtotal gastrectomy (three patients), vagotomy and hemigastrectomy (eight patients), or gastroenterostomy alone (three patients), there were no operative deaths, 74% of 27 patients available for at least a 5-year follow-up had excellent or good results, and rerecurrent ulceration developed in only one patient. These results indicate that vagotomy and resection is a satisfactory operation for recurrent peptic ulcer and that the long-term results after this operation compare favorably with those reported for cimetidine therapy.

Indwelling ileostomy valve device.

Complications after construction of a continent ileostomy may require reoperation to restore continence. Although most patients accept another operation, a few refuse further operative intervention. In such patients we have employed an indwelling ileostomy valve device. A Silastic tube with a circumferential balloon to provide a leakproof seal functionally replaces the nipple valve that has failed. In 14 patients, the valve device has maintained continuous and voluntary control over evacuation without untoward local or systemic effects. If further investigation continues to support this approach to maintaining continence, use of an indwelling ileostomy valve device might be preferable to continued creation of the nipple valve.

Hyperparathyroidism and pancreatitis. Chance or a causal association?

Of 1,153 patients with surgically confirmed primary hyperparathyroidism operated on at the Mayo Clinic between 1950 and 1975, only 17 (1.5%) had coexisting or prior pancreatitis. This frequency of association approximates the reported incidence of pancreatitis among general hospital patient populations. Other factors of possible etiologic significance in pancreatitis, such as gallstones or alcohol abuse, were present in 11 of the 17 patients. Cure of the hyperparathyroidism was usually not associated with amelioration of symptoms due to pancreatitis. A review of the available data, including experimental evidence, does not support a cause-and-effect relationship between primary hyperparathyroidism or hypercalcemia and pancreatitis.

Rectal cancer following colectomy for polyposis.

Reevaluation of 178 patients treated for multiple colonic polyposis by abdominal colectomy and restoration of bowel continuity confirmed that patients with both rectal and colonic polyps are at substantial risk of having rectal cancer develop postoperatively. Rectal cancer has not occurred in any of 35 patients who had no rectal polyps preoperatively. However, 46 (32%) of 143 patients with multiple colorectal polyposis have had cancer develop during a median follow-up of nearly 20 years. Multivariate analysis showed a highly significant association between the number of rectal polyps present preoperatively and decreased survivorship free of rectal cancer (P less than .001), and a strong correlation between the presence of cancer in the resected colon and subsequent development of rectal carcinoma (P less than .01). No correlation could be established between low anastomosis and prevention of rectal carcinoma. The risk of cancer developing in the retained segment of large bowel can be established only by extended postoperative observation.

Colonoscopic polypectomies.

One hundred ninety-three consecutive colonoscopic procedures were carried out over a recent 1-year period. An overall success rate of 92.7% was achieved for 178 attempted polypectomies. Bleeding was a complication in two patients. No colonic perforations resulted from the procedures. The results represent experience gained with 1,450 colonoscopic polypectomies.

Radionuclide image patterns of hepatic metastasis and pyogenic abscess: difficulties in differential diagnosis.

A case of hepatic metastasis with a clinical differential diagnosis of amebic and bacterial abscess is presented. Hepatic scanning with 67Ga-citrate did not diagnostically differentiate the lesion. Hepatic arteriography combined with a therapeutic trial of metronidazole proved useful in defining the lesion. An understanding of the pathophysiologic process involved in 67Ga scanning of hepatic lesions suggests a non-invasive method of discriminating among these clinical diagnostic possibilities.
