Comparison Of Curative Effect Of Laparoscopic Ileocecus-sparing Right Hemicolectomy And Traditional Laparoscopic Right Hemicolectomy

Objective: To compare the perioperative complications and short-term curative effects of laparoscopic ileocecus-sparing right hemicolectomy and traditional laparoscopic right hemicolectomy for hepatic flexure and proximal transverse colon cancers.Methods: Collect the clinical data of 61 patients（c T2N0M0 or c T3N0M0）with hepatic flexure and proximal transverse colon cancers in our hospital from November 2019 to March 2021,according to the enrollment criteria and exclusion criteria.Among them,25 patients received laparoscopic ileocecus-sparing right hemicolectomy,and 36 patients received traditional laparoscopic right hemicolectomy.They were divided into the ileocecal preservation group and the ileocecal resection group,according to whether the ileocecus was preserved or not.The baseline data,intraoperative and postoperative data were compared between the two groups.Results: There was no significant difference in baseline data,operation time,intraoperative blood loss,postoperative exhaust time,postoperative defecation time,postoperative hospital stay,overall morbidity of postoperative complications,cases of postoperative abdominal distension and cases of postoperative abdominal pain between two groups（all P>0.05）.Compared with the ileocecal resection group,the time of resuming oral intake was shorter,the number of harvested lymph nodes was less,cases of diarrhea in the late follow-up were less in the ileocecal preservation group,whose differences were statistically significant（all P<0.05）.There was no significant difference in 1-year overall survival rate and disease-free survival rate between the two groups after followup for more than one year（P > 0.05）.Conclusion: Laparoscopic ileocecus-sparing right hemicolectomy is feasible for the treatment of early hepatic flexure and proximal transverse colon cancers（c T2N0M0 or c T3N0M0）.Compared with the ileocecal resection group,preserving the ileocecus did not increase the overall morbidity of postoperative complications.and the recovery of gastrointestinal function was faster and the incidence of diarrhea was less in the ileocecal preservation group.The short-term curative effect of laparoscopic ileocecus-sparing right hemicolectomy may be comparable to that of traditional laparoscopic right hemicolectomy.
