Short- and medium-term outcomes of intracorporeal versus extracorporeal anastomosis in laparoscopic right colectomy: a propensity score-matched study

Abstract Backgrounds Though better short-term outcomes were frequently reported, differences in specimen parameters and the rate of subsequent peritoneal recurrence between intracorporeal anastomosis (IA) extracorporeal anastomoses (EA) for laparoscopic right hemicolectomy have not been analyzed. We aimed to compare pathologic oncological these two approaches. Methods retrospectively analyzed 217 consecutive patients who underwent hemicolectomies from September 2016 April 2018 classified them into IA EA groups, based on approach used. Propensity score matching analysis was performed, after which 101 included each group with matched demographics, tumor stage, localization. Results The had a longer operative time, shorter length stay, time first flatus tolerating soft diet, pain scale scores at postoperative day 3. No inter-group conversion, complication, mortality, or readmission rates found. resected colon (23.67 vs. 19.75 cm, p = 0.010) nearest margin (7.51 5.40 cancer near hepatic flexure.
