Six cases of diverticulosis of the small intestine are reported in this paper. Described in some detail is the pathological pattern of diverticula in jejunum and ileum. There are chronic courses with recurrent complaints in the epigastric region and with malabsorption syndrome which may lead to megaloblastic anaemia, steatorrhoea, and dermatosis. Acute processes are caused by perforation, diverticulitis, and haemorrhage. Ileus can develop owing to strangulation or, in less frequent cases, owing to incarceration of enteroliths. Chronic pneumoperitoneum may be attributable to massive jejunal diverticulosis.

Forty-seven patients with jejunal diverticulosis were identified at the University California, Davis Medical Center, Sacramento, by a review of patient medical records from 1980 to 1986. Fourteen patients had complications that could be directly attributed to the presence of diverticula. Six patients had evidence of a malabsorption syndrome and responded to administration of broad-spectrum oral antibiotics. One patient had recurrent bouts of an asymptomatic pneumoperitoneum. A total of seven patients required operative intervention for the following conditions: massive gastrointestinal tract bleeding, two patients; mechanical small-bowel obstruction, two patients; and diverticulitis with perforation, three patients. One patient died. Nineteen patients had symptoms of epigastric pain, early satiety, and bloating for which no cause other than the presence of jejunal diverticulosis was found. Jejunal diverticulosis was an incidental finding in 14 patients treated for other gastrointestinal tract problems.

Small bowel diverticula may cause abdominal pain, diarrhoea, malabsorption and weight loss. The same symptoms are also seen in Crohn's disease. Two elderly sisters with simultaneous small bowel diverticulosis and Crohn's disease are presented.

Jejunal diverticulosis, a marker of disordered small intestinal motility, presents varied clinical manifestations. It is important to consider this disorder in elderly patients with unexplained abdominal discomfort accompanied by signs of intermittent small bowel obstruction and malabsorption. Diagnosis can be made by a small bowel follow-through x-ray film obtained as part of the evaluation of diarrhea and obstructive symptoms. Medical therapy is helpful in controlling diarrhea and anemia, while surgical therapy can give excellent results in treating complications or refractory symptoms.

A patient with severe malabsorption due to massive diverticulosis of the small intestine developed an acute encephalopathic syndrome which responded dramatically to intravenous nicotinamide. Various mechanisms are discussed whereby nicotinamide deficiency might have occurred in this clinical context.

Serumfolate folate levels and the bacteriology of the small intestine were studied in 13 patients with jejunal diverticulosis, 29 patients with partial gastrectomy, and five patients with ileal disease. The mean serum folate level in the patients with partial gastrectomy (7.2 mmug/ml) was similar to that of control subjects but the mean level in the patients with jejunal diverticulosis (14.6 mmug/ml) was significantly higher than the mean level of the control group (8.0 mmug/ml). Five of the 13 patients with jejunal diverticulosis and two of the patients with partial gastrectomy had levels above the upper limit of the control group (> 16.6 mmug/ml), and five of six patients with jejunal diverticulosis studied excreted raised amounts of folate in the urine (> 13.2 mug in 24 hours). Serum folate in one of these patients with jejunal diverticulosis was identified chromatographically as 5-methyltetrahydrofolic acid. The mean serum folate level (9.0 mmug/ml) in the patients with partial gastrectomy who had Esch. coli in the jejunal aspirates was significantly higher than in those without Esch. coli present (mean 4.2 mmug/ml). It is suggested that in gastrointestinal disease jejunal bacteria may contribute to the serum folate level even though this remains in an accepted normal range. Some patients had low serum folate levels despite having a large number of Esch. coli in the jejunum. No evidence of malabsorption of folic acid was found in three such patients even though one had lactobacilli capable of consuming folate in the jejunum. No relationship was found between serum folate level and ileal bacteriology.

Two cases of acute jejunal diverticulitis are presented and confronted to data found in the literature. Acquired jejunal diverticulosis is a rare disease; its complications occur in a small percentage of cases. Chronic complications (malabsorption, megaloblastic anemia) should be treated medically. Acute complications (diverticulitis, perforation, haemorrhage, obstruction) require an emergency operation. Preoperative diagnosis is rarely made. Radiological or peroperative discovering of asymptomatic jejunal diverticula does not justify surgical treatment.

Duodenal diverticulosis is not a rare condition. Usually of little clinical significance, it can produce a variety of disorders such as malabsorption, hemorrhage, diverticulitis, and obstruction. The rarest complication appears to be enterolith formation and obstruction. The case presented is a 70-year-old woman with the chief complaints of intermittent abdominal pain and vomiting. At laparotomy, duodenal diverticulitis and one enterolith obstructing the distal ileum were found. The literature review presents the other 26 cases with small bowel obstruction due to an enterolith formed within a small bowel diverticulum. The diagnosis can be established only by documenting the normalcy of the gallbladder and the presence of duodenal or jejunal diverticula.

Night blindness from vitamin A deficiency was observed in a patient with intestinal malabsorption, which in turn was attributable to duodenal diverticulosis and bacterial growth. Monthly supplementation with vitamin A and correction of bacterial overgrowth with tetracycline resulted in a normalisation of plasma retinol levels and resolution of the night blindness.

Impaired intestinal function, negatively affecting food digestion and absorption, is called chronic intestinal failure (CIF). The clinical conditions leading to CIF are: fistulas, wide resections and severe damage to small bowel, and chronic intestinal stasis. In the etiology of CIF, the most frequent conditions are: Crohn's disease, postoperative peptic ulcer, mesenteric arteriopathy, radiation enteropathy, acute pancreatitis, jejunoileal diverticulosis and intestinal pseudo-obstruction. The radiologic approach to CIF can aim at: 1) diagnosing the disease and the clinical conditions causing it; 2) morphometric analysis: lesion spread, length of the extant normal small bowel and adaptive changes. Digestive tube radiology has always been considered a fundamental investigation technique to study malabsorption. Double contrast enema has increased the diagnostic capabilities of radiology. Moreover, double contrast enema allows the extraoperative evaluation, in vivo, of a new anatomic feature--i.e., intestinal length--which is a valuable sign for an exhaustive interpretation of CIF, especially of the short bowel syndrome. Thanks to double contrast enema, the changes in the length of mesenteric small bowel can be calculated in vivo (range: 150-430 cm; mean: 291 cm, SD 59). Intestinal length < 150 cm was observed only in resected patients. In 25% of cases, short small bowels were associated with CIF. Such morphometric studies, if applied to clinical practice, may yield valuable information for both diagnosis and prognosis.
