OUTCOME OF LAPAROTOMY FOR PERITONITIS IN 302 CONSECUTIVE PATIENTS IN IBADAN, NIGERIA.

backgroundPeritonitis is a life-threatening condition and requires urgent surgical management. Despite improvements in the care of patients with peritonitis, its management is still challenging and associated with significant morbidity and mortality. The aim of this study was to determine factors influencing the outcome in patients managed for peritonitis in a tertiary health institution in Nigeria.

methodA retrospective study involving 302 patients managed for peritonitis over a 3- year period. The biodata, clinical findings, diagnosis, pre-operative care, mode of anaesthesia, cadre of the surgeon, intraoperative findings, postoperative care, and the outcomes were retrieved from their records.

resultsThree hundred and two patients were operated on for peritonitis during the period. The mean age of the patients was 48 ± 12 years. Twenty (6.6%) patients had other co-morbidities, with hypertension being the most frequent. Ruptured appendicitis was the most common cause of peritonitis, 83(27.5). Twenty-eight (9.2%) patients had complications, 19 patients (6.5%) required intensive care unit admission, 25 patients (8.4%) required a second exploratory laparotomy. The mortality rate was 2.4%. There was a statistically significant association between an adverse outcome and presentation with shock, anaemia, jaundice and oliguria.

conclusionThe factors influencing outcome are similar to those of other Africa countries. However, the mortality rate in our study is lower. Peri-operative specific organ support and prompt surgical intervention should be instituted to improve outcome. We suggest a prospective study to elucidate the effect of these factors, and to determine the predictive power of the various scoring systems.
