Incisional hernia at the site of a stoma

Abstract

Objective

Incisional hernia at the site where a patient had previously had a stoma has not been clearly studied. The aim of this study is to determine the incidence and associated factors that may lead to an incisional hernia related to the reversal of an intestinal stoma.

Patients and methods

An analysis was made of 70 cases of intestinal reconnection. All patients received Cefotaxime or Ceftazidime during anaesthesia induction and two more doses at 1–8 h in the post-operative period. In all of the cases, closure of the stoma site was effected as a primary closure using no. 1 polyglycolic acid continuous suture. There followed wound lavage with iodopovidone, and the skin was closed with simple sutures using polypropylene 3/0. No drain was left in situ in any of the cases. The study considered the following aspects: demographic characteristics of the study group; illnesses giving rise to the need for stoma formation; the stoma site itself; clinical aspects, including body mass index (BMI); the incidence of incisional hernia; and any complications involving the surgical wound.

Results

At this hospital, the cause of requiring treatment with stoma formation was diverticular disease of the colon principally, and the age of the patients varied from 36 to 87 years (median 61). The incidence of incisional hernia at the stoma site was 22 cases (31.4%), presenting equally in both sexes and with greater frequency under the following circumstances: during the first year of follow-up and in patients with concomitant illnesses, principally diabetes. Local complications involving the surgical wound occurred in six cases (8.5%).

Conclusion

The incidence of incisional hernia at the stoma site was found to be 31.4% in this study, which is a high incidence of hernias with simple repair.
