RESUMO
Intracorporeal anastomosis (IA) may improve outcomes compared with extracorporeal anastomosis (EA) in minimally invasive right colectomy. This is a prospective series of robotic right hemicolectomies (RRC) with IA from one institution. 35 consecutive patients with verified or suspected right colon cancer undergoing RRC with IA, and historic control groups of 22 RRC and 40 laparoscopic right colectomies (LRC), both with EA. Primary outcome measure was length of stay (LOS). Secondary outcome measures were 30-day complication rates, readmissions, pain scores, analgesic consumption, and specimen quality. Median LOS did not differ significantly between the groups (RRC-IA, 4 days; LRC-EA, 4 days; RRC-EA, 5 days). In-hospital surgical complications Clavien-Dindo 3 + were seen in 1, 2, and 0 patients, respectively, and 3, 5, and 3 patients were readmitted to hospital within 30 days. Median pain score was 2 in all groups on postoperative day (POD) 2. Relatively more patients in the RRC-IA group received gabapentin on POD 2 (p = 0.006), but use of other analgetics did not differ between groups. Mean specimen lengths were 31, 25 and 27 cm, respectively (RRC-IA vs. LRC-EA, p = 0.003), but mesentery width, proportion of mesocolic excisions and number of lymph nodes did not differ between the groups. RRC-IA was not associated with shorter LOS, fewer complications or better specimen quality than recent controls undergoing either RRC-EA or LRC-EA.
