3D laparoscopy does not reduce operative duration or errors in day-case laparoscopic cholecystectomy: a randomised controlled trial.

ABSTRACT: BACKGROUND:Contemporary 3D platforms have overcome past deficiencies. Available trainee and laboratory studies suggest stereoscopic imaging improves performance but there is little clinical data or studies assessing specialists. We aimed to determine whether stereoscopic (3D) laparoscopic systems reduce operative time and number of intraoperative errors during specialist-performed laparoscopic cholecystectomy (LC). METHODS:A parallel arm (1:1) randomised controlled trial comparing 2D and 3D passive-polarised laparoscopic systems in day-case LC using was performed. Eleven consultant surgeons that had each performed?>?200 LC (including?>?10 3D LC) participated. Cases were video recorded and a four-point difficulty grade applied. The primary outcome was overall operative time. Subtask time and the number of intraoperative consequential errors as identified by two blinded assessors using a hierarchical task analysis and the observational clinical human reliability analysis technique formed secondary endpoints. RESULTS:112 patients were randomised. There was no difference in operative time between 2D and 3D LC (23:14 min (±?10:52) vs. 20:17 (±?9:10), absolute difference - 14.6%, p?=?0.148) although 3D surgery was significantly quicker in difficulty grade 3 and 4 cases (30:23 min (±?9:24), vs. 18:02 (±?7:56), p?

Project description:BackgroundA reliable system for grading operative difficulty of laparoscopic cholecystectomy would standardise description of findings and reporting of outcomes. The aim of this study was to validate a difficulty grading system (Nassar scale), testing its applicability and consistency in two large prospective datasets.MethodsPatient and disease-related variables and 30-day outcomes were identified in two prospective cholecystectomy databases: the multi-centre prospective cohort of 8820 patients from the recent CholeS Study and the single-surgeon series containing 4089 patients. Operative data and patient outcomes were correlated with Nassar operative difficultly scale, using Kendall's tau for dichotomous variables, or Jonckheere-Terpstra tests for continuous variables. A ROC curve analysis was performed, to quantify the predictive accuracy of the scale for each outcome, with continuous outcomes dichotomised, prior to analysis.ResultsA higher operative difficulty grade was consistently associated with worse outcomes for the patients in both the reference and CholeS cohorts. The median length of stay increased from 0 to 4 days, and the 30-day complication rate from 7.6 to 24.4% as the difficulty grade increased from 1 to 4/5 (both p?<?0.001). In the CholeS cohort, a higher difficulty grade was found to be most strongly associated with conversion to open and 30-day mortality (AUROC?=?0.903, 0.822, respectively). On multivariable analysis, the Nassar operative difficultly scale was found to be a significant independent predictor of operative duration, conversion to open surgery, 30-day complications and 30-day reintervention (all p?<?0.001).ConclusionWe have shown that an operative difficulty scale can standardise the description of operative findings by multiple grades of surgeons to facilitate audit, training assessment and research. It provides a tool for reporting operative findings, disease severity and technical difficulty and can be utilised in future research to reliably compare outcomes according to case mix and intra-operative difficulty.

Project description:ImportanceAll events that transpire during laparoscopic cholecystectomy (LC) cannot be adequately reproduced in the operative note. Video recording is already known to add important information regarding this operation.ObjectiveIt is hypothesized that additional audio recordings can provide an even better procedural understanding by capturing the surgeons' considerations.Design, setting, and participantsThe Simultaneous Video and Audio Recording of Laparoscopic Cholecystectomy Procedures (SONAR) trial is a multicenter prospective observational trial conducted in the Netherlands in which operators were requested to dictate essential steps of LC. Elective LCs of patients 18 years and older were eligible for inclusion. Data collection occurred from September 18, 2018, to November 13, 2018.Main outcomes and measuresAdequacy rates for video recordings and operative note were compared. Adequacy was defined as the competent depiction of a surgical step and expressed as the number of adequate steps divided by the total applicable steps for all cases. In case of discrepancies, in which a step was adequately observed in the video recording but inadequately reported in the operative note, an expert panel analyzed the added value of the audio recording to resolve the discrepancy.ResultsA total of 79 patients (49 women [62.0%]; mean [SD] age, 54.3 [15.9] years) were included. Video recordings resulted in higher adequacy for the inspection of the gallbladder (note, 39 of 79 cases [49.4%] vs video, 79 of 79 cases [100%]; P < .001), the inspection of the liver condition (note, 17 of 79 [21.5%] vs video, 78 of 79 cases [98.7%]; P < .001), and the circumferential dissection of the cystic duct and the cystic artery (note, 25 of 77 [32.5%] vs video, 62 of 77 [80.5%]; P < .001). The total adequacy was higher for the video recordings (note, 849 of 1089 observations [78.0%] vs video, 1005 of 1089 observations [92.3%]; P < .001). In the cases of discrepancies between video and note, additional audio recordings lowered discrepancy rates for the inspection of the gallbladder (without audio, 40 of 79 cases [50.6%] vs with audio, 17 of 79 cases [21.5%]; P < .001), the inspection of the liver condition (without audio, 61 of 79 [77.2%] vs with audio, 37 of 79 [46.8%]; P < .001), the circumferential dissection of the cystic duct and the cystic artery (without audio, 43 of 77 cases [55.8%] vs with audio, 17 of 77 cases [22.1%]; P < .001), and similarly for the removal of the first accessory trocar (without audio, 27 of 79 [34.2%] vs with audio, 16 of 79 [20.3%]; P = .02), the second accessory trocar (without audio, 24 of 79 [30.4%] vs with audio, 11 of 79 [13.9%]; P < .001), and the third accessory trocar (without audio, 27 of 79 [34.2%] vs with audio, 14 of 79 [17.7%]; P < .001). The total discrepancy was lower with audio adjustment (without audio, 254 of 1089 observations [23.3%] vs with audio, 128 of 1089 observations [11.8%]; P < .001).Conclusions and relevanceAudio recording during LC significantly improves the adequacy of depicting essential surgical steps and exhibits lower discrepancies between video and operative note.
