Clinical Efficacy of Concept of Membrane Anatomy with Complete Mesangectomy in Radical Resection of Rectal Cancer

Objective To compare the clinical efficacy between traditional laparoscopic surgery and laparoscopic surgery under the guidance of membrane anatomy with complete mesangectomy in the treatment of rectal cancer.

Methods A retrospective cohort study was conducted on 60 patients with rectal cancer who were randomly divided into control group (n=30) and observation group (n=30) in accordance with the principle of randomization.The control group received traditional laparoscopic radical resection of rectal cancer, and the observation group received laparoscopic radical resection of rectal cancer under the guidance of membrane anatomy with complete mesangectomy.The different clinical application effects of the two groups were analyzed by comparing the general data, operation time, intraoperative blood loss, and postoperative rehabilitation.

Results All the 60 patients underwent the laparoscopic radical resection of rectal cancer.No operation-related complications, conversion to laparotomy, or perioperative death cases were reported.No statistically significant differences in age, gender, operation time, postoperative exhaust time, drainage tube removal time, or postoperative complications were found between the two groups (all P > 0.05).Compared with the control group, the observation group had significantly less intraoperative blood loss and more lymph node dissected (P < 0.05).

Conclusion Laparoscopic radical resection of rectal cancer guided by the membrane anatomy with complete mesangectomy can completely remove the mesorectum, enlarge and clear the surgical field, reduce intraoperative bleeding, thoroughly remove lymph nodes, and improve the quality of surgery.
