Postoperative outcomes in patients undergoing elective general surgery after recovery from Covid-19 at a tertiary care centre: A one-year case series.

Abstract

Background Planned elective surgery had to be postponed for a large number of patients who tested positive for Covid-19 in the preoperative period. We aimed to assess the postoperative outcomes of patients who were operated on for elective indications, following recovery from Covid-19 infection. Methods We did a retrospective study of patients who underwent elective general surgery between 1 April 2020 and 31 March 2021, following recovery from Covid-19. The 30-day postoperative morbidity and mortality were analysed. The data relevant for the study were retrieved from the hospital's electronic medical records. Results Of the 109 patients included, 54.1% were women and the median (range) age was 49 (16-76) years; 53.2% of operations were performed for benign indications and the rest were for malignancies. Eighty-five (78%) patients underwent surgery following recovery from an asymptomatic Covid-19 infection and 23 (21.1%) patients following recovery from mild Covid-19 infection; 73.3% of the operations were performed following a planned delay of 2- 5 weeks from the diagnosis of Covid-19. The 30-day major postoperative morbidity (Clavien-Dindo grade ≥3) was 6.4%, the postoperative pulmonary morbidity was 0.9%, and there was no 30-day mortality. Conclusions Elective general surgical procedures can be done safely in patients who have recovered from asymptomatic and mild Covid-19 infection, following a minimum wait period of 2 weeks.
