Dose and administration time of indocyanine green in near-infrared fluorescence cholangiography during laparoscopic cholecystectomy (DOTIG) Dataset.
<p><strong><span>Introduction </span></strong></p> <p><span>Different techniques have been described to reduce the incidence of the intraoperative bile duct injury during laparoscopic cholecystectomy (LC), and Near-Infrared Fluorescence Cholangiography (NIFC) with Indocyanine Green (ICG) is one of the latest additions. Currently, there are great disparities in the usage or administration protocols of ICG.</span></p> <p><strong><span>Methods</span></strong></p> <p><span>The aim of this randomised multicenter clinical trial (RCT) is to analyse whether there are differences between the dose and administration ICG intervals to obtain good-quality NIFC during LC. In addition, different factors were analysed that may have an influence on the results of this technique. </span><span>This trial was approved by the local institutional Ethics Committee</span><span>.</span></p> <p><strong><span>Results </span></strong></p> <p><span>From June 2022 to June 2023, 200 patients were randomised in the four arms (G1: </span><span>2.5 mg ICG >3 hours prior to surgery, G2: 2.5 mg ICG 15-30 minutes prior to surgery, G3: 0.05 mg/kg ICG >3 hours prior to surgery and G4: 0.05 mg/kg ICG 15-30 minutes prior to surgery)</span><span>. We found differences in the DISTURBED score between the groups (<em>p</em><0.001), suggesting that ICG administration 15-30 minutes before surgery was worse than administration >3 hours after LC (<em>p</em>=0.02). We also observed that body mass index, gender, ASA Classification System, previous liver and biliary disease and the type of surgery had influence on NIFC. Finally, the NIFC had impact in intraoperative and postoperative complications, operative time and hospital length of stay. </span></p> <p><strong><span>Conclusion </span></strong></p> <p><span>The time of ICG administration was related to NIFC results, as well as different preoperative predictors. NIFC may also influence in surgical outcomes of LC.</span></p> <p><strong><span>Documentation in ZENODO</span></strong></p> <p>Files stored in this repository correspond to the data extracted from the CRDe RedCAP used in this study.

Laparoscopic LSCI demonstration
<p>Background: Intestinal resection causes inevitable vascular damage that cannot always be seen during an intraoperative clinical assessment of local intestinal perfusion. If left unaltered, impaired perfusion can lead to complications such anastomotic leakage (AL). Therefore, we demonstrate the use of a novel laparoscopic Laser Speckle Contrast Imaging (LSCI)-based approach to assess local intestinal perfusion during the construction of intestinal anastomoses. Methods: Three segments were isolated from the small intestine of a pig and their perfusion was compromised by coagulating 7-8 mesenteric arteries. Both clinical assessment and LSCI was used to detect the induced perfusion deficits and guide a transsection in either a well perfused, marginally perfused or poorly perfused tissue area within the segment. Bowel ends were then used to create three differently perfused anastomoses: well perfused/well perfused (anastomosis segment 1), well perfused/poorly perfused (anastomosis segment 2), and poorly perfused/poorly perfused (anastomosis segment 3). After construction of the anastomoses, a final perfusion assessment using both clinical assessment and LSCI was executed to evaluate the vascular viability of the anastomosis. Results: Laparoscopic LSCI enabled continuous assessment of local intestinal perfusion and allowed for detection of perfusion deficits in real-time. The imaging feedback precisely guided the surgical procedure and, when evaluating the final anastomotic perfusion, LSCI was able to visualize the varying degrees of perfusion whereas standard clinical assessment yielded only minor differences in visual appearance of the tissue. Conclusions: In this technical note we demonstrate a novel LSCI-based approach for intraoperative perfusion assessment. With its ability to continuously visualize perfusion in real-time, laparoscopic LSCI has significant potential to optimize anastomotic surgery in the near future.</p>

Comparison of different suture techniques for laparoscopic vaginal cuff closure
<p>Laparoscopic hysterectomy is a commonly performed procedure. However, one high-risk complication is vaginal cuff dehiscence. Currently, there is no standardization regarding thread material or suturing technique for vaginal cuff closure. Therefore, this study aimed to compare extracorporeal and intracorporeal suturing techniques for vaginal cuff closure using a pelvic trainer model. Eighteen experts in laparoscopic surgery performed vaginal cuff closures with interrupted sutures using intracorporeal knotting, extracorporeal knotting and continuous, unidirectional barbed sutures. While using an artificial tissue suturing pad in a pelvic trainer, experts performed vaginal cuff closure using each technique according to block randomization. Task completion time, tension resistance, and the number of errors were recorded. After completing the exercises, participants answered a questionnaire concerning the suturing techniques and their performance. Experts completed suturing more quickly (p < 0.001, p < 0.001, respectively) and with improved tension resistance (p < 0.001, p < 0.001) when using barbed suturing compared to intracorporeal and extracorporeal knotting. Furthermore, the intracorporeal knotting technique was performed faster (p = 0.04) and achieved greater tension resistance (p = 0.023) compared to extracorporeal knotting. The number of laparoscopic surgeries performed per year was positively correlated with vaginal cuff closure duration (p = 0.007). Barbed suturing was a time-saving technique with improved tension resistance for vaginal cuff closure.</p>
Transition from transperitoneal to retroperitoneal approach in laparoscopic living donor nephrectomy: Team-based and individual learning curve: A cross-sectional study
<p><strong><span>Background</span></strong><span>: </span><span>Laparoscopic living donor nephrectomy (LLDN) is a standard practice for kidney donor transplantation due to fewer complications associated with the treatment. Retroperitoneal approach to LLDN is thought to be more advantageous in preventing injuries to various abdominal organs. However, the transition process from transperitoneal to retroperitoneal LLDN is important to ensure the best outcome for the patients</span><span>. The aim of this study was to investigate the learning curve for the retroperitoneal approach in LLDN among urologists in an individual and team-based approach</span></p> <p><span><strong>Methods</strong>: </span><span>A retrospective analysis</span> <span>of retroperitoneal LLDN was performed on procedures performed by a kidney donor team consisting of four (4) urologists from January 2019 to January 2022 at Cipto Mangunkusumo National General Hospital, Indonesia. The data were taken from pre-existing medical records. The learning curve for the operation time, warm ischemic time, and estimated blood loss were analyzed using cumulative sum (CUSUM) analysis. Phase 1 represents the initial learning curve, the phase 2 plateau represents the period of proficiency, and phase 3 represents the mastery period.</span></p> <p><span><strong>Results</strong>: </span><span>A total of 127 retroperitoneal LLDN procedures were done during the study period by four operators with various experience. The average procedure needed to achieve proficiency was 16.5 procedures. Meanwhile, the average procedure needed to achieve mastery was 28 procedures. A shorter learning curve was achieved by operators with more experience in other laparoscopic procedures.</span></p> <p><strong><span>Conclusions</span></strong><span>: </span><span>The learning curve for transition from transperitoneal to retroperitoneal approach to LLDN is relatively short and feasible for both individuals and teams of urologists. Therefore, the transition to a retroperitoneal approach is a feasible option to reduce the complication rate of LLDN.</span></p>
