Pediatric radiologists in 40 children's hospitals in North America were interviewed to determine their choice of contrast media in the diagnosis and treatment of intussusception. The respondents indicated that barium was utilized in the vast majority of instances. Almost all indicated that they would proceed with barium enema even if there is unequivocal evidence of small bowel obstruction on the plain film examination. In over 14,000 cases of intussusception, there were 55 perforations, an incidence of approximately 1 in 250. The perforations in general were well tolerated, although there was one death.

An unusual case of intestinal obstruction due to ileal metastatic melanoma is reported. An ileocolic intussusception led to intestinal obstruction. The patient underwent palliative surgery to re-establish intestinal continuity.

Modified bilateral retroperitoneal lymph node dissection is used widely in the staging and treatment of patients with nonseminomatous germ cell testis tumors. Complications are uncommon and include vascular injury, infertility and small bowel obstruction from fibrous adhesions. Small bowel intussusception following retroperitoneal lymph node dissection has not been reported previously. We report 2 cases of small bowel intussusception after retroperitoneal lymph node dissection, and discuss the etiology and possible preventive measures.

Intussusception is an uncommon cause of intestinal obstruction in adults. Unlike children, the diagnosis of intussusception in adults is often difficult due to its usually chronic history. A case of adult ileocolic intussusception secondary to metastatic melanoma is presented to discuss the efficiency of ultrasonography, characteristic CT features and the etiology of this disease.

A total of 32 histologically documented cases of heterotopic pancreas was found in a review of the records of the department of pathology at the Chang Gung Memorial Hospital between 1977 and 1987. This review was done to ascertain the clinical significance of this uncommon entity. In 14 patients (44%), the aberrant pancreatic tissue was symptomatic; in the other 18 (56%), it was found incidentally. In the symptomatic group, the heterotopic pancreatic tissue was found in a duplication cyst of the ileum in one patient, in the common bile duct in one, in a Meckel's diverticulum in four, in the stomach in three, in a congenital duodenal diaphragm in one, in the duodenum in three, and in the ileum in one. The majority of heterotopic pancreatic tissue in the asymptomatic group was encountered in the jejunum (15 patients). Symptoms were related to complications, including obstruction of the common bile duct, mucosal ulcer with hemorrhage, intussusception, and intestinal obstruction, but not to pathologic conditions of the pancreas itself, such as pancreatitis or pancreatic cyst or neoplasm. In all of the clinically significant cases, the clinical symptoms disappeared completely after surgical removal of the aberrant tissue. In 28 cases (87%), diagnosis was made by frozen section during operation. Preoperative diagnosis of aberrant pancreas was not made in any of the cases. Histologically, all cases showed pancreatic excretory ducts; in 31 cases (97%), exocrine glands were present, and in 27 cases (84%), islets of Langerhans were discernible. There was no relationship between symptoms and the presence of islets, acini, or ducts. Mallory's phosphotungstic acid-hematoxylin stain was used to demonstrate zymogen granules in the acinar cells, and insulin, glucagon, and somatostatin were demonstrated with the horseradish peroxidase-antihorseradish peroxidase immunocytochemical staining technique; islets of Langerhans were also identified. Technetium Tc 99m scintigraphy was used to detect the bleeding source in a Meckel's diverticulum and an enteric duplication associated with ectopic gastric mucosa.

The use of ultrasound techniques has brought about considerable changes in the diagnosis and therapy of intussusception in the past few years. (1) Whenever intussusception is suspected ultrasound examination of the abdomen is the diagnostic procedure of choice; a diagnosis of intussusception can be made or excluded with an adequate degree of accuracy. (2) Ultrasound monitoring is also good for the follow-up of cecal edema after reduction of intussusception, making it possible to check that there are no pathological lead points and that complete restoration of function has been achieved. (3) There are only three absolute contraindications for attempting an enema: peritonitis, shock, and perforation. (4) Whenever there are relative contraindications for administration of an enema, e.g., long duration of symptoms, complete small-bowel obstruction, it is of the utmost importance to inform the pediatrician and the surgeon and to discuss with them the potential benefits and risks involved in an attempt at hydrostatic reduction.

We report on a two-month-old infant with bowel obstruction found to be secondary to a colonic intussusception (proved and reduced by barium enema). The finding of renal insufficiency prompted ultrasonographic renal evaluation uncovering a unilateral hydronephrosis. After resolution of the intussusception and hydration, the infant's renal functions normalized. Follow-up ultrasound study and renal scan showed resolution of the hydronephrosis. We conclude that colonic intussusception can cause renal obstruction.

Intestinal obstruction is a common postoperative complication and is usually related to peritoneal adhesion formation. A less well-recognized cause is postoperative intussusception (POI). Thirty-six instances of POI in children (aged 1 month to 18 years) were treated between 1970 and 1987. POI followed Nissen fundoplication in 9 patients, neuroblastoma resection in 5, small-bowel procedures in 4, inguinal herniorrhaphy in 3, pull-through procedures in 3, ureterostomy in 2, thoracic procedures in 2, ventral hernia in 1, nephrectomy in 1, hepatic resection in 1, Heller myotomy in 1, ventriculo-atrial shunt in 1, and gastrocystoplasty in 1. Initial symptoms included bilious vomiting or increased nasogastric drainage (after initial return of gut function) in 26 patients, abdominal distension in 24, irritability in 10, intermittent pain in 7, palpable abdominal mass in 2, rectal bleeding in 2, and lethargy in 1. The symptoms occurred 1 to 24 days (mean, 8 days) after the initial surgery. Plain abdominal radiographs revealed multiple air-fluid levels in 31 and an "adynamic ileus" in five patients. Barium contrast techniques could successfully reduce two ileocolic and one distal ileo-ileal lesions. The remainder necessitated operative management. Manual reduction was possible in 29 cases, and four children with diagnostic delay required bowel resection and an anastomosis for intestinal necrosis. The site of intussusception was ileo-ileal in 23 patients, jejunojejunal in 6, ileocolic in 5, and jejuno-ileal in 2. The diagnosis of POI should be considered in children with signs of bowel dysfunction in the early postoperative period. Contrast studies are of limited value, since most cases are confined to the small bowel. A high index of suspicion and prompt laparotomy will usually allow manual reduction of the lesion. Diagnostic delay may result in bowel necrosis.

Visceral Kaposi's sarcoma is a common manifestation of the acquired immune deficiency syndrome (AIDS). Most lesions are clinically silent, detected only by radiographic or endoscopic studies. We report the first instance of AIDS-related jejunal Kaposi's sarcoma presenting with small intestinal obstruction due to intussusception. Gastrointestinal Kaposi's sarcoma is a clinical problem that may occur more frequently in the future.

A review of 60 patients with primary small bowel tumours seen at the University Hospital, Jamaica, during the 15 year period 1971-1985, revealed that adenocarcinoma was the commonest tumour (27%), followed by smooth muscle tumour (23%), and carcinoids (11%). There were 32 malignant and 28 benign tumours. The mean age at presentation was 56 years, with a range of 4 to 85 years. The most common clinical presentation was intestinal obstruction, followed by pain, weight loss, abdominal mass and intussusception. In the majority of patients the diagnosis was not made preoperatively, and 80% with adenocarcinoma had lymph node metastases. Increased awareness of the diagnosis in symptomatic patients may result in improved survival.
