Abstract

Background

Patients with HIV/AIDS on antiretroviral therapy (ART) live longer and now require surgery for indications similar to those described for the general population. They have been previously reported to carry higher mortality and complication rates, especially septic complications. The aim of this study was to compare the outcome of major abdominal surgery in three groups of patients with different CD4 counts.

Methods

This is a prospective study comparing HIV-negative patients and two groups of HIV-infected patients on ART with different CD4 counts. The primary outcomes considered were mortality and complication rates after abdominal surgery. We emphasised on the value of CD4 as a predictor of outcome and the impact of the indication for surgery (septic versus non-septic).

Results

We included 63 patients (21 per group). The majority of patients (71 %) were operated on as an emergency and the indications were similar in all groups. The overall and the septic complication rates were both higher in the group with a low CD4 count. This resulted in a significantly longer admission period but did not result in a higher mortality rate. The duration of ART and the World Health Organisation stage of the disease did not significantly influence surgical outcomes.

Conclusions

HIV-infected patients on ART can now safely undergo major abdominal surgery with encouraging results though still relatively poorer than those of HIV-negative subjects. CD4 count remains a significant predictor of outcome and patients with a low CD4 count, however, still require closer pre- and post-operative monitoring.
