[Diverticulitis and indication for surgery--are there new data?]. / Operationsindikation bei Divertikulitis--Gibt es neue Daten?

The treatment in acute diverticulitis has undergone a considerable shift from an offensive to a more restrictive and individual indication for surgery. This review of the very recent literature with special regard to long-term observation of conservatively treated patients clearly shows that surgery is not required in any case of a first episode of severe diverticulitis, but should be recommended in high-risk patients under immunosuppression or chronic renal failure. In all other groups of patients the indication for surgery should be weighed on an individual basis after each episode, again aiming for the laparoscopic procedure. A therapeutic algorithm is proposed according to the Hansen-Stock classification.

Observations on the Kveim reaction using an animal model of granulomatous bowel disease.

Striking differences were observed between the visceral and cutaneous responses after tests with validated Kveim and normal spleen suspensions in a guinea pig model of granulomatous bowel disease. Five of six animals sensitised with BCG showed positive responses at the ileal Kveim test site whereas all six had negative cutaneous Kveim tests. Conversely, two of six animals sensitised with irradiated Mycobacterium leprae showed positive cutaneous Kveim tests and only one a positive response in the ascending colon. All six showed negative responses at the ileal Kveim test site. No positive visceral or cutaneous responses were observed in either group of animals after tests with normal spleen suspension. These findings are discussed in relation to the positive Kveim responses previously reported among patients with Crohn's disease, tuberculoid and lepromatous leprosy, and among seemingly healthy BCG vaccinated subjects. The findings provide further evidence in support of a possible mycobacterial aetiology for sarcoidosis and Crohn's disease.

[Small intestine transit anomalies in a patient with chronic abdominal pain and treated for Hansen's disease]. / Anomalies du transit du grêle chez une patiente présentant des douleurs abdominales chroniques et traitée pour une maladie de Hansen.

This new case of enteropathy due to Clofazimine provided demonstration of the diagnostic value of small bowel follow-through examination in this complication. Various small intestine anomalies have been reported: ileal or partial jejunal lesions; variations in caliber; loss of physiologic folds; irregularly outlined surface and border lacunae and persistence of suppleness of pathologic loops. Knowledge of these anomalies should avoid exploratory laparotomy, Clofazimine-induced enteropathy regressing after discontinuation of treatment. Repeat small bowel follow up examinations can be performed to review course of this regression.
