Impact of Laparoscopic Anterior Resection for Rectal Cancer with Preservation of the Left Colic Artery on Gastrointestinal Function and Postoperative Complications
Objective:To investigate the effects of laparoscopic anterior resection(LAR)with preserva-tion of the left colic artery(LCA)on gastrointestinal function and postoperative complications in patients with rectal cancer.Methods:A retrospective analysis was conducted on the clinical data of 105 patients who under-went LAR in our hospital from January 2019 to January 2022.Based on the treatment of LCA,patients were divided into the preservation group(54 cases,preserving LCA)and the non-preservation group(51 cases,not preserving LCA).Surgical parameters,lymph node dissection,preoperative and postoperative 2-day gas-trointestinal function[gastrin(GAS),motilin(MTL)],and anal function[Wexner constipation score(WCS)]were compared between the two groups.The occurrence of complications in both groups was also re-corded.Results:The preservation group had a longer operation time than the non-preservation group,and the incidence of complications was lower in the preservation group(both P<0.05).There were no significant differences in blood loss,extubation time,postoperative drainage,length of hospital stay,lymph node dissec-tion,GAS,MTL levels,and WCS scores between the two groups(all P>0.05).Conclusion:Preserving the LCA during LAR for rectal cancer does not affect lymph node dissection,gastrointestinal function,or anal function.Moreover,it may reduce the incidence of postoperative complications.
