ABSTRACT
Objective?To investigate the feasibility, safety, operating essentials and the short-term therapeutic effect of total laparoscopic resection for colorectal cancer by Natural Orifice Specimen Extraction (NOSES).?Methods?The clinical data of 50 patients underwent total laparoscopic resection for colorectal cancer by NOSES from January 2016 to June 2017 were retrospectively analyzed.?Results?All of the 50 patients with colorectal cancer successfully received total laparoscopic resection by NOSES. None of the patients had serious postoperative complications and death related to the operation. The average operating time was (140.0 ± 29.0) minutes. The blood loss was (70.0 ± 23.4) ml. The number of lymph nodes harvested were (14.0 ± 2.3). There was no bacteria infection in abdominopelvic cavity post-operation and no recurrence occurred until the end of postoperative follow- up. Postoperative time of bed rest was (2.0 ± 0.5) days. The time of the first anal exhaust was (2.0 ± 0.5) days. The postoperative hospitalization stay was (8.5 ± 3.0) days. There was none case of lung infection while one case of anastomotic leakage. No cancer cells remained in resection margin. No local recurrence and metastasis was found in all patients after follow-up for 3 to 24 months.?Conclusion?Total laparoscopic resection for colorectal cancer by NOSES is safe and feasible, and has the advantage of minimally invasive, less pain, rapid rehabilitation, good cosmetic effect and less postoperative complications.
