Overview

BackgroundExperimental work comparing 3-Dimensional (3D) and 4K ultra-high-definition endovision system (4K) indicates that the latter with double the resolution of standard 2D high-definition systems may provide additional visual cues to compensate for the lack of stereoscopic vision. There is paucity of studies comparing 3D and 4K system in clinical settings. This randomized study compares 3D and 4K systems in three laparoscopic procedures of increasing complexity.Methods139 patients undergoing laparoscopic cholecystectomy (60 patients), transabdominal preperitoneal (TAPP) repair (49 patients) and laparoscopic Heller’s cardiomyotomy with anti- reflux procedure (30 patients) between May 2018 and February 2020 were randomized to undergo surgery using either 3D or 4K systems. Primary objective was to measure total operative time. Secondary objectives were to compare workload perceived by surgeons using SURG-TLX and surgeon satisfaction score. Timings of key surgical steps and peri-operative course of the patients was also recorded. Data were analyzed using Stata Corp. 2015.ResultsPatients undergoing surgery with 3D and 4K systems were comparable in their clinical and demographic profiles. The mean total operative time in 3D and 4K groups was comparable in cholecystectomy (52.7 vs 56.2, p = 0.50), TAPP (63.8 vs 69.6, p = 0.25) and Heller’s cardiomyotomy (124.7 vs 143.3, p = 0.14) with faster hiatal dissection in 3D group(8 min, p = 0.02). Operative time was better in patients undergoing Heller’s myotomy with Angle of His accentuation with 3D by 28 min (p = 0.03). Total workload was similar in 3D and 4K groups in all the procedures but mental & physical demand was lower in 3D group in Heller’s cardiomyotomy (p = 0.03, p = 0.01), Surgeon satisfaction score was comparable in all three procedures.ConclusionOverall, 3D HD and 4K systems are comparable in performing laparoscopic cholecystectomy, TAPP and Heller’s Cardiomyotomy. Hiatal dissection time, mental and physical task load was better with 3D in Heller’s Cardiomyotomy.
