Background
This article aims to share the initial experience of the preperitoneal eTEP approach and its potential benefits in a selected group of patients. The eTEP Rives-Stoppa is a proven minimally invasive surgical technique for the treatment of ventral midline and off-midline hernias that has shown to be a solid, durable, and reproducible repair. The preperitoneal eTEP repair is a surgical technique that brings together the extraperitoneal access surgery with a preperitoneal repair for primary midline hernias avoiding posterior rectus sheath division and preservation of the retrorectus space while being able to treat simultaneous diastasis recti.
Methods
The analysis included 33 patients operated with the preperitoneal eTEP approach from September 2022 to September 2023 in patients with primary small to medium (< 4 cm) midline hernias, single or multiple defects with or without diastasis recti. Age, gender, hernia characteristics, operative time, and surgical site occurrences will be discussed, as well as fine details and landmarks in the operative technique.
Results
33 consecutive patients were operated, 19 female (57.5%) and 14 males (42.5%) between 32 and 63 years of age, the most common comorbidity found was obesity (BMI > 30). In 70% of the cases, operative time was 90 min ± 25 min. The average hospital stay was one day, while 12 went home the same day, and so far, no reoccurrences have been reported.
Conclusions
We believe the preperitoneal eTEP approach for small to medium primary midline hernias is an effective and solid repair that combines excellent features of proven surgical techniques and eliminates the need for posterior rectus sheath division while saving the retrorectus space, among other benefits that will be discussed. The reproducibility of the technique remains to be proven.

Introduction
Intraoperative indocyanine green fluorescence angiography (ICGFA) aims to reduce colorectal anastomotic complications. However, signal interpretation is inconsistent and confounded by patient physiology and system behaviours. Here, we demonstrate a proof of concept of a novel clinical and computational method for patient calibrated quantitative ICGFA (QICGFA) bowel transection recommendation.
Methods
Patients undergoing elective colorectal resection had colonic ICGFA both immediately after operative commencement prior to any dissection and again, as usual, just before anastomotic construction. Video recordings of both ICGFA acquisitions were blindly quantified post hoc across selected colonic regions of interest (ROIs) using tracking-quantification software and computationally compared with satisfactory perfusion assumed in second time-point ROIs, demonstrating 85% agreement with baseline ICGFA. ROI quantification outputs detailing projected perfusion sufficiency-insufficiency zones were compared to the actual surgeon-selected transection/anastomotic construction site for left/right-sided resections, respectively. Anastomotic outcomes were recorded, and tissue lactate was also measured in the devascularised colonic segment in a subgroup of patients. The novel perfusion zone projections were developed as full-screen recommendations via overlay heatmaps.
Results
No patient suffered intra- or early postoperative anastomotic complications. Following computational development (n = 14) the software recommended zone (ROI) contained the expert surgical site of transection in almost all cases (Jaccard similarity index 0.91) of the nine patient validation series. Previously published ICGFA time-series milestone descriptors correlated moderately well, but lactate measurements did not. High resolution augmented reality heatmaps presenting recommendations from all pixels of the bowel ICGFA were generated for all cases.
Conclusions
By benchmarking to the patient’s own baseline perfusion, this novel QICGFA method could allow the deployment of algorithmic personalised NIR bowel transection point recommendation in a way fitting existing clinical workflow.

Background
Virtual reality is a frequently chosen method for learning the basics of robotic surgery. However, it is unclear whether tissue handling is adequately trained in VR training compared to training on a real robotic system.
Methods
In this randomized controlled trial, participants were split into two groups for “Fundamentals of Robotic Surgery (FRS)” training on either a DaVinci VR simulator (VR group) or a DaVinci robotic system (Robot group). All participants completed four tasks on the DaVinci robotic system before training (Baseline test), after proficiency in three FRS tasks (Midterm test), and after proficiency in all FRS tasks (Final test). Primary endpoints were forces applied across tests.
Results
This trial included 87 robotic novices, of which 43 and 44 participants received FRS training in VR group and Robot group, respectively. The Baseline test showed no significant differences in force application between the groups indicating a sufficient randomization. In the Midterm and Final test, the force application was not different between groups. Both groups displayed sufficient learning curves with significant improvement of force application. However, the Robot group needed significantly less repetitions in the three FRS tasks Ring tower (Robot: 2.48 vs. VR: 5.45; p < 0.001), Knot Tying (Robot: 5.34 vs. VR: 8.13; p = 0.006), and Vessel Energy Dissection (Robot: 2 vs. VR: 2.38; p = 0.001) until reaching proficiency.
Conclusion
Robotic tissue handling skills improve significantly and comparably after both VR training and training on a real robotic system, but training on a VR simulator might be less efficient.
