Sequential Approach for a Critical-View COlectomy (SACCO): A Laparoscopic Technique to Reduce Operative Time and Complications in IBD Acute Severe Colitis.

Acute severe colitis is the major indication for surgery in inflammatory bowel diseases (IBD), and in particular, in ulcerative colitis (UC). A laparoscopic approach for abdominal colectomy is recommended, due to better perioperative and long-term outcomes. However, costs, time-spending, and outcomes are still a topic of improvement. We designed a standardized 10-steps, sequential approach to laparoscopic colectomy, based on the philosophy of the "critical view of safety", with the aim to improve perioperative outcomes (operative duration, estimated blood loss, complications, readmissions, reoperations, and length of postoperative stay). We performed a retrospective cohort study using data from a prospectively maintained clinical database. We included all the consecutive, unselected patients undergoing laparoscopic subtotal colectomy (SCo) for IBD between 2008 and 2019 in a tertiary IBD Italian Centre. Starting from 2015, we regularly adopted the novel Sequential Approach for a Critical-View Colectomy (SACCo) technique. We included 59 (40.6%) patients treated with different laparoscopic approaches, and 86 patients (59.4%) operated on by the SACCo procedure. The mean operating time was significantly shorter for the SACCo group (144 vs. 224 min; p < 0.0001). The SACCo technique presented a trend to fewer major complications (6.8% vs. 8.3%), less readmissions (2.3% vs. 13.5%; p = 0.01), and shorter postoperative hospital stay (7.2 vs. 8.8 days; p = 0.003). Laparoscopic SACCo-technique is a safe and reproducible surgical approach for acute severe colitis and may improve the outcomes of this demanding procedure.
