Ambulatory laparoscopic colectomies: a systematic review

Abstract Aim Ambulatory laparoscopic colectomy (ALC), meaning discharge within 24 h of surgical colonic resection, has recently been proposed in a few, selected patients. This systematic review was performed with the aim of reviewing protocols for ALC and assessing feasibility, safety and outcomes after ALC. Method A PRISMA‐compliant systematic review and pooled analysis was performed searching all English studies published until October 2022 in PubMed, Cochrane Library, Web of Science (PROSPERO, CRD42022334463). Inclusion criteria were original articles including patients undergoing ALC, specifying at least one outcome of interest. Exclusion criteria were articles reporting a robotic‐assisted procedure; unable to retrieve patient data from articles; the same patient series included in different studies. Primary outcomes were success, overall complications and readmission rates. Secondary outcomes included mortality and specific complications such us surgical site infection, anastomotic leak, ileus, bleeding, rate of ALC acceptance, and unscheduled consultation and reoperation rate. Results Among 1087 studies imported for screening, 11 were included (1296 patients). The success rate was 47% with an overall morbidity of 14%. Readmission and reoperation rates were 5% and 1%, respectively. No mortality was recorded. Protocols of ALC differ significantly among published studies. Conclusions Overall, ALC appears to be safe and feasible in selected cases with an acceptable success rate and a low risk of readmission after hospital discharge. Future studies should evaluate patients' benefits and discharge criteria, as well as uniformity and standardization of eligibility criteria. This systematic review may help inform on ALC adoption in clinical practice.
