[Results of emergengy colectomy in the management of the colon volvulus in Dakar hospital].

PURPOSE: The aim of this study was to evaluate the results of emergency colectomies for the management of colon volvulus.

PATIENTS AND

METHODS

This retrospective study was undertaken on 50 cases of colon volvulus operated in the Surgical Department of the Aristide Le Dantec teaching hospital of Dakar from January 1994 to December 2000. It concerned 42 men and 8 women with an mean age of 42 years. All patients presented an occlusive syndrome suggestive of colon volvulus, which required a laparotomy, through a xypho-pubic incision. The patients were divided into two groups. Group I concerned 13 patients who underwent an ideal colectomy and group II, 37 patients in whom we performed a colectomy associated with a temporary colostomy with either Bouilly-Volkman procedure (n = 23) or Hartman procedure (n = 14) followed one month later by intestinal continuity restoration. Mortality and morbidity were compared in the two groups.

RESULTS

The overall mortality rate was 12% (6/50). The mortality rate was 31% (4/13) in group I and 5 % (2/37) in group II. The overall morbidity rate was 14%. In group I, the morbidity rate was 15 % (2/13) and 13,5% (5/37) in group II.

CONCLUSION

In our study the mortality rate was higher after colectomy with primary anastomosis than after colectomy with temporary colostomy followed by secondary anastomosis. We recommend colectomy without anastomosis for the emergency management of the colon volvulus in Africa.
