Total 102 natural orifice specimen extraction following laparoscopic colorectal resections.

Natural orifice surgery has been used with increasing frequency in colon surgeries since the early 2000's. Our aim was to examine the patients retrospectively who underwent Natural Orifice Specimen Excision (NOSE) following laparoscopic colorectal resection. A total of 102 patients 2013 and 2018 were evaluated. The demographic characteristics, intra-operative and post-operative findings, pathology results, pain, incontinence, sexual dysfunction and cosmetic scores were examined. Mean age was 57.0 ± 14 and 52 of them (51%) were female. Specimen extraction was transanal in 72 (70%) (eventration technique in 10 patients) and transvaginal in the remaining 30 patients. The mean operating time was 272 ± 108 (median 240, range 120-540) minutes, and the mean blood loss was 92 ± 87 ml (median 54, range 5-400). The mean hospital stay was 7.0 ± 4.7 days (median 6, range 3-30). The main pain scores (visual analog score) on days 1-2-3 were 3.9 ± 2.0 (median 4, range 1-9), 3.1 ± 1.7 (median 3, range 0-8), 1.9 ± 1.5 (median 1.5, range 0-7), respectively. The mean cosmetic scores were 9.1 ± 1.5 (median 10, range 3-10). The median Wexner Incontinence score was 0 (0-9). Hospital mortality was 1% and unrelated with the NOSE. The 5-year overall survival and disease-free survival rates for cancer patients were 77.2-63.3%, respectively. NOSE has advantages in laparoscopic colorectal resections. It increases patient comfort and decreases incision related complications. CLINICAL TRIALS: www.clinicaltrials.gov (NCT04394988).
