A study of the visual symptoms in two-dimensional versus three-dimensional laparoscopy

Comparison of 3D and 2D laparoscopy: Initial experience of perioperative outcomes and clinical assessment

INTRODUCTION

This study was designed to compare three-dimensional (3D) laparoscopy and conventional two-dimensional (2D) laparoscopy in surgical performance and clinical assessment during laparoscopic radical hysterectomy with pelvic lymphadenectomy (LRHND) for treating early-stage cervical cancer.

MATERIAL AND METHODS

In this study, we included 67 consecutive patients underwent LRHND for treating early-stage cervical cancer by the experienced laparoscopic surgeons between August 2018 and December 2020. amongst these patients, 32 patients underwent 3D laparoscopy (2D group) and 35 patients underwent 2D laparoscopy (2D group). Demographic data, clinical and surgical parameters were obtained from each patient. An end-of-operation questionnaire was administered regarding subjective perception of 3D laparoscopy system.

RESULTS

Patient characteristics, including age, BMI, FIGO stage, and histology, were comparable between the two groups. Compared with 2D imaging system, 3D system significantly shortened the operation time, especially bilateral lymph node dissection time. Blood loss was lower in 3D group compared with 2D group. There were no significant differences regarding pelvic nodes retrieved, incidence of complications, hospital stay, the recovery time of bowel, abdominal drainage fluid, hospitalization costs and visual symptoms. In addition, 3D system significantly improved depth perception and precision, and reduced surgical strain and eye strain for surgeon. No statistical difference was observed in visual symptoms and adverse events between the two groups. The surgeon was more willing to accept 3D laparoscopy.

CONCLUSION

The 3D laparoscopy is safe, feasible and comfortable, with obvious advantage in depth perception, precision and surgical strain. It triggered no increase in the complications and adverse events.

Assessment of 2D and 3D imaging for patients undergoing laparoscopic bariatric surgery

<b>Aim:</b> The aim of this study is to compare the association of 2D and 3D imagery with technical performance and operative time during laparoscopic surgery. </br></br> <b> Material and methods:</b> A systematic review of the literature was conducted through an online search in databases such as PubMed, Cochrane, Embase and CNKI in order to identify articles published in English and Chinese from 2010 to 2020 that compared the clinical results of 2D and 3D laparoscopic gastric bypass surgery. </br></br> <b> Results:</b> A total of 50 articles were included in the qualitative analysis. Out of these, 5 articles that met the inclusion criteria were selected for analysis, according to which 3D laparoscopic surgery had a shorter surgery time than 2D laparoscopic surgery. </br></br> <b>Conclusions:</b> Compared with a 2D laparoscopic system, a 3D laparoscopic system can significantly reduce the operative time and errors and can increase the comfort of the surgeons performing laparoscopic gastric bypass surgery.

Short term outcomes of three dimensional versus two-dimensional laparoscopic cholecystectomy

Objective:

To compare the short-term outcomes of three dimensional (3D) versus two dimensional (2D) laparoscopic procedures used for cholecystectomy.

Methods:

This study was conducted at minimally invasive surgery center of Liaquat University of Medical Health and Sciences (LUMHS) Jamshoro Pakistan, between 15^th May 2017 to 16^th December 2017 after taking informed consent. All patients were diagnosed cases of cholelithiasis without any complications. Patients having risk factors for inability to get access to gall bladder via laparoscope and in whom the chances of conversion to open cholecystectomy were greater were not included as part of study. One group of patients underwent cholecystectomy under 3D laparoscopy while other group underwent 2D laparoscopy. Surgeons included in the study were all well-trained. The short-term outcome noted were intraoperative and postoperative complications, conversion to open, operative time, mortality and hospital stay. Visual strain and headache for the surgeon in three D laparoscopic cholecystectomy.

Results:

A total of one hundred forty patients were included in the study. Group-A consists of sixty two females and eleven males whereas Group-B comprised of fifty eight females and fifteen males. Eight percent of patients in Group-A whereas in Group-B two percent had gallbladder rupture. Fifteen percent of patients in Group-A whereas 5.4% from Group-B had bleeding from liver bed. One patient from Group-A had CBD (Common Bile Duct) injury. Post-operatively two (2.73%) patients from Group-A had port site bleeding. Six (8.21%) patients had port site infection in Group-A.

Conclusion:

Three dimensional was found to have low incidence of intra-operative and post-operative complications compared to 2D laparoscopic cholecystectomy.

Impact of accommodation, convergence and stereoacuity on perceived symptoms and surgical performance among surgeons

BACKGROUND

Minimally invasive surgery (MIS) is not without impact on surgeons' neck/shoulder/head and eyes. However, the mechanisms for concurrent symptoms are not clear. This study aims to examine the effect of visual impairments on physical symptoms and surgical performance among surgeons performing simulated surgical tasks using two-dimensional (2D) and three-dimensional (3D) viewing modes.

METHODS

Gynaecologists with experience in laparoscopy performed four simulated surgical tasks in the 2D and 3D viewing modes. Visual parameters (accommodation, convergence and stereoacuity) were measured prior to commencement. Objective performance measures were derived from the laparoscopic tasks, and surgeons also self-reported their mental and physical workload using the NASA-TLX. In addition, perceived symptoms were measured using Visual Analogue Scales, the Simulator Sickness Questionnaire and the Computer Vision Syndrome Questionnaire.

RESULTS

Seventeen healthy gynaecologists participated in this study. There were significant relationships between visual impairments and both the perceived symptoms and surgical performance scores of MIS surgeons. Surgeons with a higher number of accommodation/convergence dysfunctions and/or poorer stereoacuity tended to have poorer objective performance scores on simulated surgical tasks in both viewing modes. NASA-TLX scores indicated that surgeons with poorer stereoacuity also perceived themselves to have been less successful at accomplishing tasks. However, these surgeons also reported less intense physical symptoms and simulator sickness.

CONCLUSIONS

Surgeons' performance for the simulated surgical tasks correlated with visual functions, and it also impacted on the symptoms experienced. Regular screening of surgeons' vision and vision therapy may be required to decrease physical symptoms and improve surgical performance.
