A Comparison of Natural Orifice Versus Transabdominal Specimen Extraction Following Laparoscopic Total Colectomy.

Natural orifice surgery has been increasingly used in colon surgery since the early 2000s. However, it is rarely used for total colectomy. In this study, we aimed to retrospectively compare natural orifice specimen extraction (NOSE) with transabdominal specimen extraction in patients undergoing laparoscopic total colectomy. Twenty-six patients who underwent laparoscopic total colectomy between 2013 and 2017 were enrolled and the patients were divided into two groups: NOSE (n = 13) and transabdominal group (n = 13). The patients' demographic characteristics, perioperative and postoperative outcomes, pathology results, visual analog scale scores, and cosmetic scores were compared. There was no significant difference between the two groups in terms of demographic characteristics as well as perioperative and postoperative outcomes, including complications. Benign pathologies were more common in the NOSE group (85% versus 15%, P = .001). The pain scores of the postoperative first, second, and third days were significantly lower in the NOSE group 4.1 ± 2.1 versus 7.1 ± 1.3 (P = .005), 3.7 ± 2.2 versus 6.0 ± 1.5 (P = .003), and 2.2 ± 2.0 versus 4.1 ± 0.9 (P = .03), respectively. As expected, the mean cosmetic score was significantly better in the NOSE group (8.3 ± 1.5 versus 6.7 ± 1.8, P = .02). NOSE combined with laparoscopic total colectomy provided better patient comfort in benign diseases and small-sized malignant diseases.
