Alternative method for the diagnosis of acid cases of unknown cause: Transvaginal natural orifice transluminal endoscopic surgery. Issue 2 (16th November 2020) - Mat, Emre
Abstract: Aim: To evaluate the efficacy and reliability of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) technique in making the diagnosis of ascites with unknown cause. Methods: Seven patients with ascites with unknown cause and diagnosed with vNOTES between November 2018 and May 2019 were analyzed retrospectively. The following data were collected retrospectively: body mass index, age, parity, previous abdominal or pelvic surgery, total operating time, perioperative complications and visual analog scale scores for evaluation of postoperative pain. After general anesthesia and disinfection, a 2–3 cm incision was made in the posterior fornix of the vagina. In all of the vNOTES procedures, a handmade glove port system comprised of a glove‐wound retractor NOTES port was used. Results: Transvaginal natural orifice transluminal endoscopic surgery for diagnostic peritoneoscopy was successfully performed in seven patients. Following postoperative pathological examination; three patients were established to have peritoneal carcinomatosis, one patient abdominal tuberculous, one patient ovarian fibroma, one patient ovarian mature cystic teratoma and one patient stomach cancer. In 1‐year follow‐up period after vNOTES procedure, no adverse events occurred in patients. Conclusion: In making histological diagnosis of ascites with unknown cause, vNOTES is a feasible, safe and efficient technique. Due to its high performance in diagnosis, this technique helps to initiate treatment early in some diseases in addition to preventing unnecessary treatment and examination in benign diseases. Besides, via obtaining a detailed and enlarged image of abdominal cavity, this procedure also guides the clinician in the evaluation of the suitability of patient for operation.
