Analysis of peritoneal lavage cytology and microbiology in patients with total laparoscopic resection for colorectal cancer by NOSES

Abstract

Objective To analyse the results of peritoneal lavage cytology and microbiology in patients with total laparoscopic resection for colorectal cancer by NOSES. Methods Examination of cytology and microbiology of peritoneal lavage were performed for thirty colorectal cancer patients who underwent total laparoscopic resection by NOSES from January 2016 to April 2018, then compared with the other studies reported about peritoneal lavage for cytology and microbiology of open and laparoscopic radical resection for colorectal cancer at home and abroad. Results Thirty colorectal cancer patients who underwent total laparoscopic resection by NOSES were performed the examination of peritoneal lavage for cytology and microbiology. There was no patients with positive cytology result (positive rate 0%), ten patients were with positive microbiology result (positive rate 33.3%) , no patients were with abdominopelvic cavity infection and tumor recurrence in abdominopelvic cavity. Our results were similar to the other studies reported about peritoneal lavage for cytology (0%~45.5%) and microbiology (20%~32.5%) of open and laparoscopic radical resection for colorectal cancer at home and abroad. Conclusion Total laparoscopic resection for colorectal cancer by NOSES didn't increase the rate of intraperitoneal implantation of colorectal cancer cells and intra-abdominal infections. It is worthy of clinical application and promotion conforming to the principle of aseptic and non tumor.
