Villous tumors of the duodenum.

Five cases of villous tumors of the duodenum are reported, all of which involve the ampulla of Vater. Three of the five lesions contained either infiltrating carcinoma or carcinoma in situ. Although preoperative endoscopic biopsy was performed on all tumors no malignancy was identified. Frozen sections done at the time of operation on the three patients with carcinoma also failed to identify malignancy. One patient underwent pancreaticoduodenectomy and four patients had local excision of the tumor. Three of the patients treated with local excision developed recurrence and two subsequently had pancreaticoduodenectomy. Because of the difficulty in making an accurate diagnosis and the chance of recurrence when local excision is employed, strong consideration should be given to pancreaticoduodenectomy as the initial form of treatment of these lesions.

Gastrocolic and gastrojejunocolic fistulae: report of twelve cases and review of the literature.

Seven gastrocolic and five gastrojejunocolic fistulae were recorded at Charity Hospital between 1940 and 1970. Such fistulae occurred in males more often than females. In this series, as in others, the most common cause was gastric surgery for peptic ulcer disease. Pain, diarrhea, and weight loss were clinical findings in half the patients; anemia, leukocytosis, electrolyte disturbances and hypoalbuminemia were common laboratory findings. A fistula was demonstrated radiologically in nine of the twelve patients, management of these patients included no operation (3); two-stage procedure (2); and one-stage procedure (7); with a recent trend toward the one-stage procedure. A case report of a fistula resulting from postoperative complications of perforative appendicitis in which a successful combination of hyperalimentation and diverting colostomy was used is presented.
