Twenty episodes of serious gastrointestinal complication occurred in 14 of 85 (16%) consecutive patients less than 17 years old who underwent renal homograft transplantation. These complications consisted of small-bowel obstruction, ulceration, pancreatitis, hepatitis, ascites, and severe gastroenteritis. Only 1 patient died as a consequence of the complication--a much lower mortality rate than that reported for gastrointestinal complications of renal transplantation in adults. Radiographic findings were diagnostic in the majority of cases and aided in the prompt administration of therapy.

There is a high incidence of primary colonic intussusceptions in infants and children in Africa. The case histories of 37 patients are reviewed. Of the varieties described, the caecocolic intussusception (16 patients) presents as an intestinal upset, often mild, with symptoms of colic and vomiting. In many of these patients there is known to be an intestinal infestation with Ascaris lumbricoides. This often leads to a delay in establishing the correct diagnosis. Colocolic intussusception (13 patients) gives rise to more acute abdominal symptoms. On clinical assessment, signs of intestinal obstruction are found and there is usually an intra-abdominal mass which can be palpated in the left colon. Further confirmatory evidence of intussusception is the finding of occult blood in stools. There is an unusually high incidence of sigmoid intussusceptions in infants (8 patients). The diagnosis of this form of intussusception is often delayed owing to inadequate clinical assessment of prolapsed bowel at the anal orifice. The length of the prolapsed bowel, the curved nature of the prolapse and the possible demonstration of a sulcus between the prolapsed bowel and the anal canal wall, aid in diagnosis.

In 95 consecutive cases of cavaderic renal transplantation followed up for 1 to 83 months (mean 23.1 months) 17 complications developed in the upper gastrointestinal tract of 15 patients; these included duodenal ulcer in 12 and gastric ulcer, esophagitis, hemorrhagic gastritis, small-bowel obstruction and small-bowel perforation in 1 each. The occurrence of a complication was not related to the patient's age, sex, blood group or use of cigarettes or alcohol, the duration of hemodialysis before transplantation, the tissue match or the number of infusions of immunosuppressive medication. One patient died of the complication. The peptic ulcers that developed after transplantation were successfully managed conservatively in 69% of cases. Since surgical treatment in patients whose immune response has been suppressed is associated with an increased frequency of complications such as disruption of suture lines, it is preferable to reserve it for those in whom complications develop that are unresponsive to conservative measures.

Histiocytic lymphoma of the ileocecal region developed in a patient with multiple myeloma following successful long-term alkylating agent therapy. Five and one-half years after the diagnosis of myeloma, while in remission on cyclophosphamide therapy, the patient experienced severe abdominal right lower quadrant pain due to a large cecal lymphoma. A right hemicolectomy was performed with relief of symptoms. However, 9 months later, while still asymptomatic, routine physical examination revealed a recurrent right lower quadrant tumor. Radiation therapy decreased the size of the mass, but five months later partial small bowel obstruction occurred because of recurrent lymphomatous infiltration. The patient died 7 years after the diagnosis of myeloma with extensive abdominal lymphoma. There was no evidence of recurrent myeloma after the initial remission on cyclophosphamide therapy. This patient adds to the growing literature of a second malignancy occurring after prolonged successful chemotherapy of a primary neoplasm.

In uremic patients under long-time dialysis and after kidney transplantation surgical diseases with severe complications may occur, such as gastro-duodenal ulcers, inflammatory and ischaemic diseases of the colon, acute pancreatitis, intestinal obstruction. Most of the complications have only poor symptoms. If complications are suspected, an "aggressive diagnostic regimen" is mandatory. The incidence of cancer is higher in these patients. Complications can be diminished by prophylactic operations, such as gastric resection in gastro-duodenal ulcer. A restriction in elective and emergency operations has no longer a place in these patients.

We report on an 89-year-old female admitted with signs of intestinal obstruction in whom three independent adenocarcinomas of the proximal jejunum were found. Multiple foci of pyloric gland metaplasia, glandular hyperplasia and dysplasia, carcinoma-in-situ, and several varieties of adenocarcinoma were identified on microscopic examination of 14 cm of excised jejunum. Multifocal adenocarcinoma of the small intestine is extremely rare. We are not aware of any case harboring the complex changes described herein.

An appreciation of haustral anatomy as well as the anatomic relationships of the colon serve as the basis of plain film colon identification in the patient beyond infancy. An evaluation of the newborn colon in the normal state and with low colonic obstruction indicates that these principles apply here as well. Newborns with suspected intestinal obstruction should be studied in multiple projections early in their clinical course. A search should be made for haustrations and characteristic anatomic relationships of the colon, as well as gas in the rectum. Although clear differentiation of large from small bowel obstruction may not always be possible, these principles should serve as a basis for a systematic approach to the newborn abdominal plain film.

An infant is reported in whom severe malabsorptive symptoms developed shortly after birth associated with intermittent episodes of intestinal obstruction. Plexiform neurofibromatosis involving the terminal ileum was found at laparotomy at the age of 6 mo. The infant died from gastrointestinal functional impairment at the age of 1 yr.

Two patients are reported which were operated for complications of small bowel diverticula. One was operated for a retroperitoneal tumor caused by a perforated diverticulum, which led to an inflammatory mass of the mesentery. In another patient adhesions produced acute intestinal obstruction.

Preoperative irradiation for adenocarcinoma of the rectum and sigmoid does not always limit the surgery to an abdominoperineal resection. From 1960 to 1976 anterior resection and primary anastomosis of the bowel has been performed in 13 patients with adenocarcinoma of the rectum and sigmoid whose tumor had been irradiated with 5000 rads with small pelvic fields. The inferior surgical resection line was within or very near the edge of the radiation field in 10 patients. In no instance was the superior resection line irradiated. Compared to a group of 79 patients treated with anterior resection only, the preoperatively irradiated patients had lower incidence of pelvic and anastomotic tumor recurrence, but a higher incidence of anastomotic leak and subsequent adhesions and intestinal obstruction. We stress that if irradiated rectum is considered for forming the anastomosis, a temporary "protective colostomy" should be strongly considered at the time of the surgery.
