No results posted yet for this study

Summary

The purpose of this study is to investigate the short-term and long-term outcomes between natural orifice specimen extraction surgery (NOSES) and totally laparoscopic right hemicolectomy (TLRH). The hypothesis is that NOSES could achieve good short-term and oncological outcomes for right colon cancer patients.

Interventions

PROCEDURE

Laparoscopic Right Hemicolectomy With Transrectal/transvaginal Specimen Extraction (NOSES)

Transvaginal extraction, begins with the irrigation and disinfection of the vagina, followed by a transverse incision in the posterior fornix. The assistant then utilizes oval forceps to carefully extract the specimen bag through the incision, which is subsequently closed with continuous full-thickness sutures, using barbed sutures to ensure secure closure. Similarly, transrectal extraction begins with irrigation of the rectum using a dilute iodine solution, followed by a longitudinal incision along the anterior wall of the upper rectum. The specimen, along with the protective sleeve, is then removed using oval forceps, and the incision is closed with a continuous full-layer running suture once the specimen has been completely extracted.

PROCEDURE

Totally laparoscopic right hemicolectomy (TLRH)

Totally laparoscopic right hemicolectomy (TLRH), which involves performing intracorporeal anastomosis and specimen extraction through a small abdominal incision, further enhances the benefits of minimally invasive surgery. In the TLRH group, following the stapled side-to-side anastomosis, a small horizontal incision is made about 2 to 3 cm above the symphysis pubis, at the junction of the pubic hairline, to allow for specimen removal.
