Volvulus of the small intestine is a condition of bowel obstruction due to knotting and twisting of the small intestine. Two types of volvulus are described: 1) primary small intestinal volvulus where no predisposing factors exist, and 2) secondary volvulus where congenital or acquired conditions promote twisting of the small intestine. Over a 5-year period, 18 patients (eleven men and seven women) presenting volvulus of the small intestine are operated in the Emergency Surgery Clinic of the University Hospital "Queen Giovanna", representing 8.7 per cent of the total of 206 cases of small intestinal mechanical ileus (incarcerated herniations involving the small intestine are not included in the series). Primary volvulus is found in one patient. In those presenting secondary volvulus adhesions are the commonest underlying cause of small intestinal rotation--13 cases, next ranking primary tumor of the small intestine--one case, Meckel's diverticulum--one, carcinosis of peritoneum--one, and one patient with small intestine volvulation around colostomy. The most frequently encountered symptoms and laboratory examinations performed are analyzed. Intestinal necrosis is established in four instances (22 per cent). One patient dies of peritonitis and polyorganic insufficiency. Volvulus of the small intestine should be mandatorily considered in patients presenting mechanical ileus of the small intestine. Early operative intervention is a therapeutic approach contributing to preclude intestinal necrosis.

From 1976 to 1995, 23 children, 4 boys and 19 girls, were treated at our department for sacrococcygeal teratomas (SCT). Their records were analyzed retrospectively, considering age at operation, histopathology, recurrences, and long-term evolution. One died on the 1st day of life following tumor rupture with hemorrhagic shock without surgical intervention. All others were operated upon at a mean age of 4.2 days for those 19 (= 82%) who were diagnosed in the neonatal period and whose histology proved benign. In the remaining 3 children, in whom tumor manifestation did not occur before 11 months, 13 months, and 10 years of age, respectively, histopathologic evaluation revealed 2 carcinomas and 1 yolk-sac tumor, and all 3 recurred. Overall, 5 patients died, the 1 mentioned above, 1 due to volvulus after laparotomy, and 1 from multiple associated congenital malformations. Two deaths were related to malignancy, whereby only 1 was a malignant teratoma diagnosed at the original operation. Eight children had recurrences, 2 were benign and 6 malignant, with 3 of the latter having been graded benign on histology of the primary tumor. Of the 18 surviving patients, 17 (93.5%) returned for clinical review following a standardized protocol. The average interval from the primary surgery was 12.3 years (range 3.5-22 years). Four had malignant tumors with a recurrence-free period of from 9 to 14 years; 5 (29.4%) had urinary or anorectal functional impairment. One child with a patulous anus presented with fecal soiling. Two reported nocturnal enuresis, 1 associated with perineal anesthesia. One had a neurogenic bladder with overflow voiding and bilateral third-degree vesicoureteral reflux. Second-degree reflux was found in the last patient. We conclude that follow-up after surgery for SCT should not only search for tumor recurrence but include the diagnosis and treatment of possible secondary urinary and/or fecal incontinence.
