We have examined complications involving the defunctionalized bowel in 119 intestinal bypass patients. In this group, we found a 66% of incidence of bypass enteropathy. Pneumatosis cystoides intestinalis was present in three patients, severe blood loss in three, localized ulcerations in two, intermittent or chronic intussusception of the proximal jejunal stump in 10, and extensive stenosis relating to tight fibrous adhesions in one patient. The stenosis may become manifest as an obstructive process only after reconstitution of normal bowel continuity. Bacterial overgrowth in the bypassed small bowel was the primary cause for most of the lesions. A consistent diagnostic finding, suggesting disease in the excluded bowel, was ileal distention and the presence of gas-fluid levels on upright abdominal x-rays. Definitive diagnoses of ulceration, intussusception, and/or obstruction were sometimes possible only during laparotomy. Because the bypassed bowel cannot be examined with conventional techniques, these various abnormalities must be suspected when ill-defined abdominal complaints are observed in bypass patients. Metronidazole, to suppress anaerobic organisms, or suitable broad spectrum antibiotics can relieve the various lesions of the inflammatory process, whereas appropriate surgical procedures may be required for some of the chronic or recurrent complications.

Pneumatosis cystoides intestinalis is a rare condition that can be located in any part of the gastrointestinal tract. It is usually associated with a wide variety of gastrointestinal or pulmonary diseases. The primitive form is much less frequent and usually involves the left colon. The pathogenesis of pneumatosis cystoides intestinalis is still unclear. The mechanical theory, which is the most accepted explanation, postulates that gas is forced into the bowel wall by breaks in the mucosa; this is more likely to occur when the intraluminal pressure is higher, as happens in obstructive conditions, during endoscopies, or during infections from gas-forming bacteria. Pneumatosis cystoides is often asymptomatic, representing an occasional finding during investigations for other abdominal conditions. Complications occur in about 3% of cases and include obstruction, intussusception, volvulus, haemorrhage and intestinal perforation. When presenting acutely or in association with other abdominal conditions the differential diagnosis is rarely a problem. More important is to diagnose asymptomatic primitive submucosal pneumatosis of the colon, in order to avoid unnecessary intestinal resections. The Authors present the case of a patient with pneumatosis coli who underwent laparotomy for a suspected colonic lipomatosis of the right colon.

Pneumatosis cystoides intestinalis (PCI) is an uncommon disease that generally lacks symptoms and is rarely associated with intussusception. A 29-year-old man visited our hospital for right upper abdominal pain. Computed tomography (CT) scan revealed multiple air-filled cysts along the intestinal wall and a pseudokidney sign in the transverse colon. A gastrographin enema examination showed a so-called crab finger appearance and multiple elevated translucency in the transverse colon. From these findings, the diagnosis of intussusception associated with PCI was made. The enema and manipulative reduction improved the intussusception. Comparing the enema findings before and after the reduction, we thought that mobile cecum could play an important role in the intussusception. Colonoscopy was performed after the reduction and showed multiple elevated lesions in the ascending colon, which were similar to cluster of grapes. The CT scan of the next day revealed no recurrence of the intussusception, and the patient has not had symptoms of recurrence ever since.
