Comparison between the 4K ultra-high definition (UHD) and high definition (HD) endoscopic systems for transoral endoscopic thyroidectomy.

ABSTRACT: Background:The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is the most recently introduced method of minimally invasive thyroid surgery. To our knowledge, no studies have compared TOETVA outcomes using different laparoscopic systems. This study compared outcomes of TOETVA using conventional high definition (HD) and ultra-high definition (UHD) equipment. Methods:Medical data and surgery videos of 62 patients who randomized to undergo thyroid lobectomy by TOETVA using an HD or UHD system from August 2018 to April 2019 were retrospectively reviewed. Endoscopic procedures were divided into four phases: flap creation to isthmectomy (phase I); strap muscle division to upper pole ligation (phase II); trimming recurrent laryngeal nerve (phase III); and ligation of Berry's ligament to complete resection (phase IV). Results:Of the 62 patients, 28 underwent TOETVA using an HD device and 34 using a UHD device. The clinical characteristics of the two groups were not different. Mean operating time for lobectomy was similar in the HD and UHD groups (44.19±9.94 versus 43.47±12.19 min, P=0.825). The times required for phases I (15.02±5.33 versus 13.67±5.44 min, P=0.397); II (12.89±2.84 versus 13.17±5.22 min, P=0.816); III (9.85±4.36 versus 9.98±4.55 min, P=0.918); and IV (6.43±3.69 versus 6.65±3.45 min, P=0.840) were also similar in the HD and UHD groups. The numbers of retrieved lymph nodes did not differ significantly in the HD and UHD groups (3.26±2.62 versus 3.45±2.81, P=0.807). Conclusions:Applying a UHD system in TOETVA resulted in outcomes similar to those observed with a conventional HD system. Operation time tended to be lower, especially for flap dissection, and numbers of harvest lymph nodes tended to be higher in the UHD group. Large-scale studies are needed to assess the advantages of the UHD system.

Project description:BackgroundVision is an important and defining element of laparoscopy and significantly affects the outcome of surgery in terms of time, error, and precision. Several new imaging systems have become available for laparoscopic surgery, including three-dimensional (3D) high-definition (HD) and two-dimensional (2D) ultra-high-resolution (4K) monitors. 3D HD systems offer a number of potential benefits to surgeons and patients over traditional 2D systems, including reduced operating time, blood loss, and hospital stay. However, the performance of 3D systems against the new, ultra-high definition 4K systems is barely known and highly controversial. There is a paucity of studies comparing them in clinical settings. The aim of this study is to compare 2D 4K and 3D HD perspectives in gastric bypass surgery.MethodsForty-eight patients with an indication for gastric bypass will be randomized to receive laparoscopic gastric bypass surgery using either 2D 4K or 3D HD systems. The operations will be performed by a well-coordinated team of three senior surgeons. The primary outcome is operative time. Secondary outcomes include intraoperative complications, blood loss, operator workload as assessed by the validated Surg-TLX questionnaire, and postoperative complications according to the Clavien-Dindo classification. An interim analysis is planned after enrollment of 12 participants for each group.DiscussionThis prospective, randomized trial is designed to test the hypothesis that the use of a 3D HD system will result in a significant improvement in operative time compared to a 2D 4K system in bariatric surgery. The objective is to provide clinical evidence for new laparoscopic imaging systems and to evaluate potential benefits.Trial registrationThis trial is registered at clinicaltrials.gov under the identifier NCT05895058.
