Tuberculoses compliquées du tube digestif

Aim of study. – To report cases from Vietnam of intestinal tuberculosis disease, which is uncommon but did not disappeared in occidental countries.

Materials and methods. – Seventy-six patients were included into this retrospective study. Mean age was 40 years and sex ratio M/F was 6. Diagnosis was established on pathological examination of resected specimen or on presence of Mycobacterium tuberculosis or by polymerase chain reaction.

Results. – Intestinal obstruction or subobstruction was the most usual symptom (68%), and thereafter peritoneal symptoms with pain and tenderness (17%). Five patients had intractable digestive haemorrhage. Thirty-six patients had no past history or active pulmonary tuberculosis (47%). Lesions of stenosis on barium enema and thickness of intestinal wall on CT-scan were no specific. Sixty-two patients were operated on (82%) and 14 were not. Surgical techniques differed according symptoms, site and type of lesions. Intestinal resections were performed in half of the patients, others undergoing stomies or enterolysis. There were eight postoperative deaths (13% of patients operated on), seven out of these deaths were attributable to cachexy. In the postoperative period, all the patients were medically treated and follow-up in the antituberculosis centre of Hanoi.

Conclusion. – Symptomatology and operative findings of intestinal tuberculosis are similar to those observed in Crohn's disease, and sometimes in amoeboma or lymphoma. In face of stenosis and intestinal wall thickness, probability of intestinal tuberculosis is high in endemic area, but diagnosis must be suspected in occidental countries, mainly in patients immigrated coming from these area, patients with immuno-deficiency even if they did not have pas or present pulmonary tuberculosis.
