Gastrointestinal disease in middle Africa is changing. The traditional patterns were high frequencies of parasitic and infectious diseases and sigmoid volvulus, and low incidences of colonic polyps, carcinoma of the colon, appendicitis, diverticulosis, ulcerative colitis and Crohn's disease. The current disease patterns are compared with those for gastrointestinal disease in developed countries and etiological factors are discussed.

There are three main groups of indications of lower digestive tract endoscopy: (1) endoscopy may be performed to detect adenomatous polyps and thus prevent colorectal cancer by systematic excision of these polyps before they become invasive malignancies; (2) it may also be performed in patients whose symptoms (e.g. pain, diarrhoea or anaemia) may be due to a lesion of the colon. It usually provides evidence of such diseases as colorectal adenocarcinoma, ulcerative colitis, Crohn's disease, pseudomembranous colitis, post-irradiation colitis, collagen colitis, ischaemic colitis or colonic angiodysplasia; (3) finally, emergency endoscopy can be used in case of rectal haemorrhage, where it is often completed by haemostasis, or in case of volvulus, where it removes the occlusion.

Eight patients with cystic fibrosis had chronic abdominal pain and the other features of distal intestinal obstruction syndrome. Coexistent abdominal pathology was shown in six patients. Two had a small bowel volvulus, and the others had Crohn's disease, a small bowel fistula, appendix abscess, and an ovarian dermoid. Opiate abuse exacerbated symptoms in two other patients.

Athymic nude mice, injected with a cell-free filtrate of intestinal tissue from patients with Crohn's disease, have been shown to express antigens in their lymph nodes to which sera from patients with Crohn's disease contain antibodies. In the present study, immune reactivity was assessed with a histochemical indirect immunoperoxidase assay on paraplast-embedded tissue sections. The reactive lymph node cells were identified as sinus macrophages. We confirmed earlier findings of immunofluorescence studies that the reaction showed some antibody specificity, the proportion of patients with Crohn's disease who were positive (84%) being higher than of patients with ulcerative colitis (29%). However, reactivity of Crohn's disease sera was found to be antigen nonspecific, as it was equally observed with lymph nodes of mice primed with saline or with homogenates from patients with ulcerative colitis, diverticulitis, or volvulus. Hence, this nude mouse model does not seem appropriate to identify a transmissible etiology of Crohn's disease.

Fifty out of 228 patients recorded on the U.K. Home Parenteral Nutrition Register have died. The earliest to die was at 10 days following the commencement of home parenteral nutrition (HPN), and the longest to die was after 5 1/2 years. Half of the patients who died, did so within 6 months of commencing HPN. Sixty % died of their underlying disease. Most patients with scleroderma or an underlying malignancy are dead within a year of commencing HPN. In contrast, patients with Crohn's disease or the short bowel syndrome due to volvulus do well. In only 14 patients was death attributable to the administration of HPN. In this group the main causes were septicemia, SVC thrombosis, and hepatic failure. Our study suggests that HPN should be used in patients with malignancy and scleroderma only in exceptional circumstances and that further work is necessary for the prevention of SVC thrombosis.

Between January, 1977, and March, 1986, 200 patients were registered as receiving home parenteral nutrition (HPN) in the UK and the Republic of Ireland. Although 28 centres contributed case-reports, 75% of the cases were registered by 7 centres. Most patients started treatment between the ages of 10 and 40 years, a reflection of the high incidence of Crohn's disease during these decades. The three main indications for HPN were Crohn's disease (90 patients), mesenteric vascular disease (27), and extensive small-bowel resection for volvulus or other benign enteric disease (14). 85 patients required treatment for less than 1 year and 17 have been on treatment for more than 2 years. Patients whose indication for HPN was a primary intestinal disease had a better quality of life than did those in whom the intestinal failure was secondary to a systemic disorder. Of the 108 patients who have completed treatment 56 have been able to resume enteral nutrition through adaptation of the remaining bowel, or closure of a fistula. 34 have died, 19 as a consequence of the underlying disease and 10 of complications of treatment. The incidence of catheter-related sepsis varied between 0.2 and 0.9 episodes per year of treatment (overall 0.35) depending on the length of experience of the supervising centre.

Intestinal volvulus in patients with Crohn's disease is rare and we could find only one report of sigmoid volvulus with active Crohn's colitis. We have seen a 54-year-old woman with long-standing Crohn's disease who developed large-bowel obstruction. After eventual detorsion of the sigmoid volvulus, we found that her ileum was involved with active Crohn's disease and that her colonic mucosa was free of mucosal lesions. In this case, we suspect that the reactivation of the ileal Crohn's disease as well as other features commonly associated with Crohn's disease contributed to the development of sigmoid volvulus by causing fixation, torsion, and dilatation of distal bowel.

We performed an economic evaluation of a home parenteral nutrition (HPN) program by measuring the incremental costs and health outcomes for a cohort of 73 patients treated at our institution from November 1970 to July 1982. Over a 12-year time frame, we estimate that HPN resulted in a net savings in health care cost of $19,232 per patient and an increase in survival, adjusted for quality of life, of 3.3 years, compared with the alternative of treating these patients in hospital with intermittent nutritional support when needed. This result was sensitive to assumptions made about the cost of the alternative treatment strategy. When these assumptions were most unfavorable to the HPN program, we estimated that HPN resulted in incremental costs of $48,180 over 12 years, $14,600 per quality-adjusted life-year gained. We conclude that the cost-utility of HPN compares favorably with other health care programs, when HPN is used to treat patients with gut failure secondary to conditions such as Crohn's disease or acute volvulus. Since only one patient with active malignancy was enrolled in our HPN program, these results should not be extrapolated to patients with active malignancy.

The expression of gastrointestinal cancer antigen, CA 19-9, and of carcinoma-associated antigen, CA-50, was studied in formalin-fixed and paraffin-embedded tissue from 18 patients with ulcerative colitis, 29 with Crohn's disease in the colon, four with diverticular disease, and eight with sigmoid volvulus. None of the patients with inflammatory bowel disease showed strong dysplasia or had manifest carcinoma. Both antigens were expressed frequently in patients with inflammatory bowel disease. Of the 18 patients with ulcerative colitis, 17 were positive for both CA 19-9 and CA-50, and of the 29 with Crohn's colitis, 21 were positive for CA 19-9 and 22 for CA-50. No distinct differences in antigenic expression were found between Crohn's disease and ulcerative colitis. CA-50 was expressed in normal colonic mucosa from 10 of 12 patients with sigmoid volvulus or diverticular disease, and such mucosa was positive for CA 19-9 in three of the four patients with diverticular disease and in two of the eight patients with sigmoid volvulus. It is concluded that immunodetection of CA-50 or CA 19-9 is of limited value in the differential diagnosis of inflammatory bowel disease. The usefulness of these antigens as markers for precancerous changes in inflammatory bowel disease is also doubtful, since the expression is also frequent in cases of inflammatory lesions, with no obviously increased risk of malignancy.

The object of this study is to focus attention on the causes of intestinal obstruction in Libya. In this study, spread over 30 months and involving 114 patients, the most common cause was the entrapment of bowel in an external hernia. Postoperative adhesions accounted for obstruction in a third of our patients, and 59 per cent of them followed appendicectomy. Biliary lithiasis is the most common surgical disease in Libya, yet there was only one instance of gallstone ileus in this series. Sigmoid volvulus and intestinal lymphoma were also rare, and tubercular stricture and Crohn's disease were remarkable by their absence. There were no cases of idiopathic intussusception during or immediately following Ramadan.
