Background: During Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) the surgeon operates exclusively through a single vaginal entry point, leaving no external scarring.

Objectives: To evaluate the learning curve of vNOTES hysterectomy by experienced gynecologists based on surgical times and short-term outcomes.

Methods: A retrospective study was conducted of the first 25 vNOTES hysterectomy surgeries performed from July to December 2018 at Rambam Health Care Campus by a single surgeon. The primary outcome was hysterectomy time. Secondary outcomes included intra-operative bleeding, length of hospitalization, postoperative pain, and need for analgesia. Socio-demographic and clinical data were retrieved from patient electronic medical charts.

Results: Median age was 64.5 years (range 40–79). Median hysterectomy time was 38 minutes (range 30–49) from the first cut until completion. Comparisons between median hysterectomy time in the first 10 hysterectomies and in the 15 subsequent procedures demonstrated a significant decrease in median total time: 45 minutes (range 41–49) vs. 32 minutes (range 30–38), respectively (P = 0.024). The median estimated intraoperative blood loss decreased from 100 ml (range 70–200) in the first 10 hysterectomies to 40 ml (range 20–100) in the subsequent procedures (P = 0.011)

Conclusions: vNOTES hysterectomy is feasible by an experienced gynecologist, with an exponential improvement in surgical performance in a short period as expressed by the improvement in hysterectomy time, low complication rates, negligible blood loss, minimal post-surgical pain, fast recovery, and short hospitalization. vNOTES allows easier and safer access to adnexal removal compared to conventional vaginal surgery.

Background: In the last decade the number of robotic devices and the medical procedures utilizing them increased significantly around the world.

Objective: To evaluate the implementation of robotic surgeries in Israel in various surgical disciplines.

Methods: We conducted a retrospective study accessing information about the annual purchases of robots, the number of physicians trained for their use, and the number of robotic surgeries performed each year, according to indications of surgery and the disciplines of the operating medical staff. The data were taken from the database of Intuitive Surgical Inc.

Results: Six robots were purchased by six medical centers in Israel during the years 2008–2013. There are currently 150 physicians trained to use the robot in one of the simulators of Intuitive Surgical Inc. Of them, 104 are listed as active robotic surgeons. Most of these physicians are urologists, gynecologists, or general surgeons. The number of robotic surgeries increased each year in all fields in which it was implemented. In 2013, 975 robotic surgeries were performed in Israel. Of them, 52% were performed by urologists; 80% of which were radical prostatectomy. 

Conclusions: The use of robotic surgery increased considerably in Israel over recent years, in urology, gynecology, general surgery, and otolaryngology. Despite the lack of conclusive evidence of the advantages of robotic surgery over the laparoscopic approach, the market power and the desire to be at the technological forefront drive many medical centers to purchase the robot and to train physicians in its use.
