[Percutaneous drainage of perisigmoid abscesses of diverticular origin].
OBJECTIVE
The aim of this multicentric retrospective study was to report the results on the percutaneous drainage of perisigmoid abscesses during acute sigmoid diverticulitis in 12 patients.


METHODS
Between January 1993 and March 2000. 12 patients with a perisigmoid diverticular abscess were treated by antibiotic therapy and percutaneous drainage of the abscess. The patient population consisted of eight males and four females (mean age: 50.2 years). The diagnosis was established in two out of seven cases by enema, in four cases out of seven by abdominal ultrasonography, and in eight cases out of 11 by CT scan. Percutaneous drainage was carried out in all cases, and was guided by ultrasonography (n = 3) and CT scan (n = 9). The mean duration of drainage was 6.5 days.


RESULTS
No drainage-associated complications were observed. Drainage combined with antibiotic treatment provided satisfactory results in ten out of 12 cases. Two cases of failure of the method occurred, and the patients involved were operated on day 4 and week 5 by colectomy with protective lateral ileostomy. There was an early recurrence of the abscess in three patients, who were treated by the Hartmann procedure in one case, and by one-stage colectomy in two cases. Five patients underwent a secondary one-stage colectomy. Two patients in whom no residual abscess was detected were not operated on at the time of the study.


CONCLUSIONS
Percutaneous drainage of perisigmoid diverticular abscesses combined with antibiotic therapy provided efficient treatment in ten out of 12 cases. Secondary one-stage colectomy was performed in seven out of the eight patients requiring further surgery.
