Objective:
This study aims to compare the outcomes of single stapling natural orifice specimen extraction surgery (ssNOSES) with double stapling natural orifice specimen extraction surgery (dsNOSES) in anterior resection for rectal cancer.
Methods:
A total of 100 patients with rectal cancer were selected from the Colorectal Department of the Second Hospital of Hebei Medical University. These patients underwent Natural Orifice Specimen Extraction Surgery (NOSES) between July 2018 and July 2020. Fifty patients who underwent ssNOSES were compared with fifty patients who underwent dsNOSES. The comparison focused on patient demographics, surgical outcomes, and complications, with a particular emphasis on operative time, cost, and complications.
Results:
Four cases of anastomotic leakage were observed in the dsNOSES group, and this group also incurred higher costs. Although the surgical time for ssNOSES was longer, the procedure was associated with lower costs and no cases of anastomotic leakage.
Conclusions:
ssNOSES is a cost-effective and safer alternative to dsNOSES. Furthermore, the surgical time for ssNOSES can be reduced through training and experience.
