PRIMARY EXPERIENCE OF NATURAL ORIFICE SPECIMEN EXTRACTION SURGERY (NOSES) FOR RECTAL CANCER

Abstract

AIM: to demonstrate the first results of natural orifice specimen extraction surgery (NOSES) for rectal cancer.PATIENTS AND METHODS: in the period from June 2019 to October 2019 five NOSES for rectal cancer were performed in the hospital. The following factors were evaluated: age, gender, BMI, ASA, operation time, intraoperative blood loss, intraoperative and postoperative complications, duration of postoperative rehabilitation, need for narcotic analgesics.RESULTS: mean age of patients was 61.2 years. Mean BMI was 25.9 kg/m2 . Mean ASA score was 2. Mean operative time was 225 minutes. Mean intraoperative blood loss was 45 ml. One intraoperative complication occurred – defect of anastomosis in the point of crossing of 3 stapler sutures. One postoperative complication occurred – postoperative ileus. Narcotic analgesics were not used. Mean duration of postoperative stay was 9.8 days. The primary results demonstrate feasibility of NOSES for rectal cancer with adequate qualification of colorectal surgeon.CONCLUSION: NOSES is a promising technique for rectal cancer surgery. However, the further experience and randomized trials are required.
