Open or Laparoscopic Mesolectal Excision in Low Rectum Cancer

"We performed laparoscopic dissection of the lateral pelvic lymph node for thirty patients while we performed open lateral pelvic lymph node dissection for the remaining thirty patients.~Performed surgical approaches were abdominoperineal resection, internal sphincter resection, and low anterior resection. All performed surgical procedures included lateral pelvic lymphadenectomy in addition to performing total mesorectal excision.~Choosing whether to perform unilateral or bilateral lymphadenectomy depends on lymph nodes invasion by cancer was on one side or both sides."
