[Acute abdomen as a complication of a duodenal duplication cyst]. / Abdomen agudo como complicación de un quiste de duplicación duodenal.

The authors report an exceptional case of acute abdomen caused by the necrosis and perforation of a duodenal duplication cyst in a 23 year-old-patient. The cyst was located at the anterior and lateral surface of the duodenum, between its first and second portion. The patient underwent a cephalic duodenopancreatectomy (Whipple's procedure) because of the intimate adherence of the necrotic and inflammatory mass to duodenum and head of the pancreas. The histological examination of surgical specimen confirmed the diagnosis, showing a cystic structure lined with an epithelium and a common muscle wall shared by the cyst and the duodenum. There was no communication between the cyst and duodenal lumen.

[Acute obstruction of the colon secondary to biliary lithiasis]. / Obstrucción aguda de colon secundaria a litiasis biliar.

Gallstone ileus is an unusual cause of mechanical obstruction of the gastrointestinal tract; but obstruction of the colon by a gallstone is an even more rare event, and there are few references in the literature. We describe the cases of two elderly women who were admitted to the Emergency Service with a mechanical obstruction of the colon and air in the biliary tract. A barium-enema examination showed the presence of a foreign body in the sigmoid colon; this was found to be a gallstone in a subsequent colonoscopy in one of the patients; a precise preoperative diagnosis was not possible in the other. In both cases the obstruction was caused by a gallstone impacted in the sigmoid colon and a cholecystocolonic fistula was evident in a postoperative barium enema examination. Correction of the obstruction is the main objective of initial treatment. The repair of the fistula can be performed at the same time or at a later date.

[True pancreatic cysts in adults]. / Quistes verdaderos del páncreas en el adulto.

True or congenital cysts of the pancreas in adults are extremely rare entities. We describe two cases of true cysts located in the head of the pancreas, which presented with symptoms of epigastric pain, palpable mass and jaundice. CT scan was useful to demonstrate the location and extent of the lesion and its relation with neighbouring structures, but failed to determine the nature of the cyst. Diagnosis was obtained by the histological study of the cystic wall at surgery.

[Colorectal polyps. Treatment and clinical course]. / Pólipos colorrectales. Tratamiento y evolución.

We report the results of the treatment and follow up of 61 patients with polyps of the colon and rectum, who underwent surgical intervention between 1983 through 1991. The mean age was 56 years (range from 41 to 56 y.) and 53% of the patients were males. The majority of the polyps were located in the anorectal region, n = 32 (52.4%) and sigmoid colon n = 17 (27.8%). Tubular adenomas in n = 38 patients and villous adenoma in n = 19, were the most frequent histological types. We have found polyps with invasive carcinoma in 15 (24.6%) cases. The polyps were resected by transanal resection in 15 patients, by colectomies in 11, and 10 patients underwent colectomy for removal of their polyps. Surgery was indicated when the polyp had a base too wide to be removed by colonoscopy or when malignancy was demonstrated by biopsy. There were 10 (19.6%) recurrences during the first three years of follow up. The histological examination showed malignant changes in 4 polyps. Villous adenomas, n = 7 constituted the histological type with more recurrences. Recurrences were treated by local resection in half of the cases. The morbidity was 9.8% and mortality was 3.3%. Surgery when indicated, allows to obtain free margins from tumor, to determine lymph node involvement and to establish the stage.
