Homemade Glove Port for Single-Incision Pediatric Endosurgery (SIPES) Appendectomy-How We Do It

Comparison of a single-access glove port with a SILS™ port in a surgical simulator model using MISTELS

Background

Recent advances in laparoscopy both in human and veterinary medicine have looked at means of being less invasive by using single-port access surgery as opposed to multiport access surgery. The glove port has gained popularity as a cost-effective alternative to commercially available single-port access devices. The primary aim of this study was to compare the glove port to the SILS™ port in a simulator model using the first two MISTELS (McGill inanimate system for training and evaluation of laparoscopic skills) tasks (peg transfer and pattern cutting).

Methods

Twenty-two novices were enrolled in this experimental study. Each participant had 60 min to practise both MISTELS tasks using two-port laparoscopy. Thereafter participants performed both tasks using the glove and SILS™ port with scores being calculated based on task completion time and errors. Higher scores were indicative of better performance. Participants were assigned into two groups with the starting order of the single ports being randomly selected. A self-evaluation questionnaire with three questions was completed by each participant after testing, rating each port.

Results

Significantly (p < 0.05) higher scores were achieved using the glove port compared to the SILS™ port when performing both tasks. The glove port was subjectively evaluated as easier to use with more manoeuvrability of the instruments than the SILS™ port.

Implications of the study

The glove port’s improved manoeuvrability and ease of use make it a cost-effective alternative to the SILS™ port, for use in single-port laparoscopic veterinary surgery.

20 Years of Single-Incision-Pediatric-Endoscopic-Surgery: A Survey on Opinion and Experience Among International Pediatric Endosurgery Group Members

Aim/Background: Assessment of current role and future trends of Single-Incision-Pediatric-Endoscopic-Surgery (SIPES) in pediatric surgery among International Pediatric Endosurgery Group (IPEG) members two decades after introduction. Materials and Methods: An online survey was conducted between December 2019 and April 2020 on behalf of the IPEG Research Committee. All IPEG members were contacted by e-mail and asked to complete an anonymous questionnaire that included 39 items on SIPES. Results: One hundred eighty-four practicing pediatric surgeons completed the questionnaire from a pool of 890 IPEG members. The majority (76%) of respondents performed SIPES for more than 6 years with the following caseload per month: 1 case (31%), 2-5 cases (30%), 6-10 cases (24%), and >10 cases (17%). The four most commonly performed procedures were appendectomy (95%), Meckel diverticulectomy (55%), treatment of ovarian pathologies (43%), and U-stitch gastrostomy (40%). Complex reconstructive SIPES procedures were performed rarely. Most surgeons (95%) stated that better cosmesis is the predominant advantage of SIPES procedures. The majority of respondents (70%) felt that there is no convincing scientific evidence that SIPES offers benefits to multi-port minimally invasive procedures. Conclusion: Twenty years after introduction of SIPES, this technique has found its place in pediatric endoscopic surgery. Eighty percent of participating IPEG members of this survey apply SIPES for cases of lower complexity, such as appendectomy mainly for cosmetic reasons. The fact that 70% of respondents state that the scientific evidence for the benefits of SIPES is not convincing suggests that further studies and discussion on this technique are needed.
