Initial experience using a handheld fully articulating software-driven laparoscopic needle driver in TAPP inguinal hernia repair

Abstract

Background The laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is a widely performed minimally invasive operation, but can present considerable ergonomic challenges for the surgeon. Our objective was to determine if a novel handheld software-driven laparoscopic articulating needle driver can mitigate these difficulties. Methods The video recordings of a consecutive series of TAPP cases by a single surgeon using the articulating device were compared with a series of cases using straight-stick laparoscopy. Two critical steps of the procedure were analyzed for time: mesh fixation and peritoneal suture closure. These steps were then compared before and after 10 initial consecutive cases to analyze whether the surgeon demonstrated improvement. A cost analysis was also performed between the two techniques. Results For mesh fixation, the surgeon averaged 227 s using tacker devices, compared with 462.4 s using the novel laparoscopic device (p = 0.06). For the peritoneal closure component of the operation, the surgeon improved the time per suture pass during closure from 60.61 s during the first 10 cases to 38.84 s after the first 10 cases (p = 0.0004), which was comparable to the time per stitch for standard laparoscopy (34.8 s vs 34.84 s, p = 0.997). Left-sided inguinal hernia repairs using the articulating device demonstrated a significantly longer time per stitch during peritoneal closure compared to the right side after first 10 cases (left: 40.62 s; right: 27.91, p = 0.005). Our direct cost analysis demonstrated that suture closure of the peritoneum using the articulating device was more cost-effective than tack fixation. Conclusions After only a 10 case initial experience, a laparoscopic hand-held articulating needle driver is comparable to standard laparoscopy to complete suture mesh fixation and peritoneal closure for TAPP inguinal hernia repair. Further, the feasibility of suture mesh fixation minimizes the need for costly tacker devices. This instrument appears to be a promising tool in this largely minimally invasive era of hernia repair.

The Advances in Computer Vision That Are Enabling More Autonomous Actions in Surgery: A Systematic Review of the Literature

“…However, maybe we should be asking ourselves which is the best way forward, more specifically, are complete robotic surgical systems with tele-manipulation really the best way forward? Maybe the surgeon needs to be kept in the loop by keeping the surgeon at the bedside and developing more handheld collaborative robots [6,72].…”
