Abstract
PURPOSE Open ureteral reimplantation is considered the standard surgical approach to treat distal ureteral strictures or injuries. These procedures are increasingly performed in a minimally invasive and robotic-assisted manner. Notably, no series comparing perioperative outcomes and safety of the open vs. robotic approach are available so far. METHODS In this retrospective multi-center study, we compared data from 51 robotic ureteral reimplantations (RUR) with 79 open ureteral reimplantations (OUR). Both cohorts were comparatively assessed using different baseline characteristics and perioperative outcomes. Moreover, a multivariate logistic regression for independent predictors was performed. RESULTS Surgery time, length of hospital stay and dwell time of bladder catheter were shorter in the robotic cohort, whereas estimated blood loss, postoperative blood transfusion rate and postoperative complications were lower than in the open cohort. In the multivariate linear regression analysis, robotic approach was an independent predictor for a shorter operation time (coefficient - 0.254, 95% confidence interval [CI] - 0.342 to - 0.166; p < 0.001), a lower estimated blood loss (coefficient - 0.390, 95% CI - 0.549 to - 0.231, p < 0.001) and a shorter length of hospital stay (coefficient - 0.455, 95% CI - 0.552 to - 0.358, p < 0.001). Moreover, robotic surgery was an independent predictor for a shorter dwell time of bladder catheter (coefficient - 0.210, 95% CI - 0.278 to - 0.142, p < 0.001). CONCLUSION RUR represents a safe alternative to OUR, with a shorter operative time, decreased blood loss and length of hospital stay. Prospective research are needed to further define the extent of the advantages of the robotic approach over open surgery.

[PMID: 38086254 DOI: 10.1016/j.jss.2023.11.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 10/01/2023] [Accepted: 11/12/2023] [Indexed: 02/25/2024]
Abstract
INTRODUCTION Learning minimally invasive suturing can be challenging, creating a barrier to further implementation, especially with the development of easier methods. Nevertheless, mastering intracorporeal knot tying is crucial when alternative techniques prove inadequate. Therefore, the minimally invasive surgery (MIS) suturing skills of MIS experts are compared with a group of novices during their learning curve on a simulator. METHODS The novice participants repeatedly performed the intracorporeal suturing task on the EoSim MIS simulator (up to a maximum of 20 repetitions). The experts (>50 MIS procedures and advanced MIS experience) completed the same task once. The first and last exercises of the novices and the expert tasks were all blindly recorded and assessed by two independent assessors using the Laparoscopic Suturing Competency Assessment Tool (LS-CAT). Additionally, objective assessment parameters, "time" and "distance", using instrument tracking, were collected. The scores of the experts were then compared with the novices. RESULTS At the end of the training, novices significantly outperformed the experts on both the expert assessment (LS-CAT: 16.8 versus 26.8, P = 0.001) and objective parameters (median time: 190 s versus 161 s, P < 0.001; median distance: 6.1 m versus 3.6 m, P < 0.001). Although the experts showed slightly better performance than the novices during their first task, the difference was not significant on the expert assessment (LS-CAT experts 16.8, novices 20.5, P = 0.057). CONCLUSIONS Our findings underscore the significance of continued MIS suturing training for both residents and surgeons. In this study, trained novices demonstrated a significant outperformance of experts on both quantitative and qualitative outcome parameters within a simulated setting.

Abstract
Endometriosis is a prevalent yet often underdiagnosed condition characterized by the presence of endometrial-like tissue outside the uterus, leading to significant morbidity and impaired quality of life. A timely and accurate diagnosis of endometriosis is essential for effective management and improved patient outcomes. This review provides a comprehensive overview of the current diagnostic landscape of endometriosis, including clinical evaluation, imaging modalities, biomarkers, and laparoscopy. The strengths and limitations of each diagnostic approach are critically evaluated, alongside challenges such as delayed diagnosis and misinterpretation of findings. The review emphasizes the importance of multidisciplinary collaboration, standardized diagnostic protocols, and ongoing research to enhance diagnostic accuracy and facilitate early intervention. By addressing these challenges and leveraging emerging technologies, healthcare professionals can improve the diagnosis and management of endometriosis, ultimately enhancing the well-being of affected individuals.

[PMID: 38407555 DOI: 10.1111/ans.18892] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 01/09/2024] [Accepted: 01/22/2024] [Indexed: 02/27/2024]
Abstract
BACKGROUND Laparoscopic bariatric surgery relies on technically challenging intracorporeal suturing for critical parts of the operation. Barbed sutures have been developed to provide an alternative to suturing for certain manoeuvres within a procedure. Barbed sutures theoretically negate the need for knot tying and allow for continuous application of tension; however the barbs can unintentionally adhere to surrounding tissues. We describe a case series of three patients who developed V-Loc™ (barbed) suture related small bowel obstruction (SBO) to promote awareness of this unusual but preventable complication. METHODS Medical records of patients diagnosed with V-Loc™ related SBO between 2018 and 2021 at a tertiary centre were reviewed. Data regarding presentation, diagnosis, management and outcomes were obtained. RESULTS Three patients were identified where V-Loc™ sutures were aetiologically related to early post-surgical small bowel obstruction secondary to small bowel adherence to barbed suture tail or adhesions between barbed suture tail and unintended viscera. In these cases, non-absorbable V-Loc™ sutures were used to close the small bowel mesenteric defect at Roux-en-Y gastric bypass surgery. All patients required adhesiolysis at re-look laparoscopy prior to resolution. All patients were discharged home well after relook laparoscopy. CONCLUSION Overly long or exposed V-Loc™ suture tails can result in SBO following laparoscopic bariatric surgery. Cutting the suture tail as close as practical to the final throw of the suture and/or covering exposed suture ends may prevent this complication.

Intracorporeal vs. extracorporeal open and closed knot tying techniques in laparoscopy: A randomized, controlled study. Heliyon 2024; 10:e25178. [PMID: 38322852 PMCID: PMC10844269 DOI: 10.1016/j.heliyon.2024.e25178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 01/16/2024] [Accepted: 01/22/2024] [Indexed: 02/08/2024] Open
Abstract
Objective Tying knots during suturing is one of the most challenging tasks in laparoscopic surgery. Therefore, measures aimed at ensuring both the ease and speed of knot tying not only benefit the surgeon but can also reduce operating time significantly. This study compared extracorporeal and intracorporeal knot tying techniques using a Szabo pelvic trainer model from the Gynaecological Endoscopic Surgical Education and Assessment program. Design The students tied intra- and extracorporeal knots using closed- and open-jaw knot pushers. Using an artificial tissue suturing pad in a certified Szabo pelvic trainer, students tied three knots using each technique according to block randomization. Task completion time, knot strength, knot-spread ability, and number of errors were recorded. The Wilcoxon test and mixed-effects models were used to analyze the results. After completing the exercises, participants answered a questionnaire concerning knot-tying techniques and their performance. Setting University Hospital Basel, which provides tertiary-level clinical care. Participants Fifty-seven medical students with no experience in laparoscopy voluntarily signed up for this study. Results Open and closed extracorporeal knot tying was significantly faster (p < 0.001, p < 0.001, respectively), more precise (p = 0.007, p = 0.003), and associated with reduced knot-spread ability (p < 0.001, p < 0.001) compared to intracorporeal knot tying. Open- and closed-jaw knot pushers were shown to be equal in terms of speed (p = 0.563), knot-spread ability (p = 0.49), and precision (p = 0.831). The study participants rated open (30 %) and closed (49 %) extracorporeal knot tying as more intuitive than intracorporeal (21 %) knot tying. Improved concentration was significantly correlated with tighter knots (p = 0.011). Conclusions Students achieved significantly better results using extracorporeal knot-tying techniques than intracorporeal ones, including greater speed, tighter knots, and optimized precision. These results suggest that beginners in the field of laparoscopy should be encouraged to practice extracorporeal knot-tying techniques.

Abstract
BACKGROUND Competition-based learning (CBL) facilitates learning through competitions. At the 2022 & 2023 Annual SAGES meetings, we evaluated a CBL experience (TOP GUN Shootout) developed from a modified version of the previously validated TOP GUN Laparoscopic Skills and Suturing Program. The project sought to evaluate the TOP GUN Shootout's (TGS) ability to enhance participant engagement in pursuit of laparoscopic surgical skills. METHODS Participants competed in the TGS. Their scores (time and errors) were recorded for: Fundamentals of Laparoscopic Surgery Peg Pass, Cup Drop Task, and Intracorporeal Suturing. All participants completed a 10-question satisfaction survey on a 7-point Likert scale, with questions assessing 3 domains: (1) capability/confidence in MIS skill performance prior to the competition; (2) applicability and satisfaction with TGS's capacity to develop MIS skills; and (3) interest in seeking additional MIS training and appropriateness of CBL in MIS training. Descriptive statistics were used to evaluate these areas. RESULTS Overall, 121 participants completed the TGS, of whom 84 (69%) completed the satisfaction survey. The average age was 32.9 years, 67% were males. On average (+/- SD), participant satisfaction was 5.04 (+/- 2.08) for Domain 1, 6.20 (+/- 1.28) for Domain 2, and 6.58 (+/- .95) for Domain 3. CONCLUSION Participants described an overall lack of confidence in their MIS skills prior to the 2022-2023 Annual SAGES conference. Participants felt that this brief CBL experience, aided in the development of their MIS skills. Furthermore, this brief CBL experience may inspire learners to seek out further training of their MIS skills.

Shi Z. Laparoscopic vs. open surgery: A comparative analysis of wound infection rates and recovery outcomes. Int Wound J 2023; 21:e14474. [PMID: 37905679 PMCID: PMC10898397 DOI: 10.1111/iwj.14474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 10/17/2023] [Accepted: 10/17/2023] [Indexed: 11/02/2023] Open
Abstract
As medical technology continues to evolve, it becomes crucial to distinguish the outcomes of traditional versus modern surgical techniques. This was a retrospective cohort study, conducted to compare the wound infection rates and recovery outcomes between laparoscopic and open surgery (OS) in 180 patients. Participants were divided into laparoscopic (n = 105) and OS (n = 75) groups. Comprehensive data, including demographics, surgical details, and postoperative outcomes, were extracted. Wound infection rates, as measured by Wound Asepsis Score, were prioritized alongside recovery indicators such as duration of hospital stay and postoperative pain. The laparoscopic group had a mean operative time of 57.19 minutes, while the OS group required 85.10 ± 15.18 minutes (p < 0.05). Laparoscopic surgeries resulted in an average blood loss of 120.76 ± 13.3 mL compared to 170.01 ± 17.19 mL for OS (p < 0.05). The laparoscopic group had significantly reduced (p < 0.05) average hospital stays (2.1 ± 1.1 days) than the OS group (4.4 ± 2.1 days). Although the laparoscopic group had lower incidence of surgical site infection (4.76%) than the OS group (9.33%), this difference was not statistically significant (p > 0.05). On postoperative days 1, 3, and 7, the Visual Analog Scale assessment of pain in the laparoscopic group revealed significantly reduced pain (p < 0.05). Laparoscopic surgery appeared to offer distinct advantages over conventional open surgery, especially in terms of operative durations, recovery rates, and postoperative pain management. This study highlighted the potential of laparoscopic approaches for specific surgical interventions, as well as the importance of patient-specific surgical strategy decision-making.

Abstract
Purpose We compared the "inverse 9" laparoscopic suturing and knot-tying (LSKT) method to the traditional LSKT method in a validation study to demonstrate the "inverse 9" method's superiority and effectiveness in laparoscopy. Methods On the basis of their experience in laparoscopic surgery, 78 trainees were divided into two groups, with 52 inexperienced trainees in group A and 26 experienced trainees in group B. In group A, 52 trainees were randomly allocated to either group A1 ("inverse 9" LSKT training) or group A2 (traditional LSKT training). In group B, experienced trainees were randomly assigned to receive "inverse 9" LSKT training (group B1) or continuing training in the traditional LSKT method (group B2). All trainees received the same instruction and assessment and were asked to provide a subjective assessment of the two training methods at the end of the training. Results The trainees in groups A1, A2, and B had similar average ages and were mostly male. After training, all showed preliminary mastery of LSKT (P < 0.05). The trainees in groups A1 and B1 achieved learning proficiency in the fifth assessment, while those in group A2 achieved it in the sixth assessment. The trainees in groups A1 and B1 showed lower difficulty in achieving mastery and lower operation fatigue scores (P < 0.05), and 61.50 % of the trainees in group B preferred the "inverse 9" method in subjective evaluation. Conclusion As a novel LSKT technique, "inverse 9" offers a multitude of benefits. In addition to ensuring a simpler operation and effectively reducing the knot-tying time, it also involves a shorter learning curve than traditional LSKT methods. As such, it can be easily mastered and widely adopted as a standard LSKT technique.

Video-based learning of coping strategies for common errors improves laparoscopy training-a randomized study. Surg Endosc 2023; 37:4054-4064. [PMID: 36944741 PMCID: PMC10156798 DOI: 10.1007/s00464-023-09969-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Accepted: 02/19/2023] [Indexed: 03/23/2023]
Abstract
AIMS The aim of this study was to investigate whether shifting the focus to solution orientation and developing coping strategies for common errors could increase the efficiency of laparoscopic training and influence learning motivation. The concept of coping has been particularly defined by the psychologist Richard Lazarus [Lazarus and Folkman in Stress, appraisal, and coping, Springer publishing company, New York, 1984]. Based on this model, we examined the use of observational learning with a coping model for its effectiveness as a basic teaching model in laparoscopic training. METHODS 55 laparoscopically naive medical students learned a standardized laparoscopic knot tying technique with video-based instructions. The control group was only offered a mastery video that showed the ideal technique and was free from mistakes. The intervention group was instructed on active error analysis and watched freely selectable videos of common errors including solution strategies (coping model) in addition to the mastery videos. RESULTS There was no statistically significant difference between the intervention and control groups for number of knot tying attempts until proficiency was reached (18.8 ± 5.5 vs. 21.3 ± 6.5, p = 0.142). However, there was a significantly higher fraction of knots achieving technical proficiency in the intervention group after first use of the coping model (0.7 ± 0.1 vs. 0.6 ± 0.2, p = 0.026). Additionally, the proportion of blinded attempts that met the criteria for technical proficiency was significantly higher for the intervention group at 60.9% vs. 38.0% in control group (p = 0.021). The motivational subscore "interest" of the validated score on current motivation (QCM) was significantly higher for the intervention group (p = 0.032), as well as subjective learning benefit (p = 0.002) and error awareness (p < 0.001). CONCLUSION Using video-based learning of coping strategies for common errors improves learning motivation and understanding of the technique with a significant difference in its qualitative implementation in laparoscopy training. The ability to think in a solution-oriented, independent way is necessary in surgery in order to recognize and adequately deal with technical difficulties and complications.

JOURNAL OF SURGICAL EDUCATION 2023; 80:302-310. [PMID: 37683093 DOI: 10.1016/j.jsurg.2022.09.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 08/17/2022] [Accepted: 09/25/2022] [Indexed: 09/10/2023]
Abstract
BACKGROUND Laparoscopic intracorporeal suturing is important to master and competence should be ensured using an optimal method in a simulated environment before proceeding to real operations. The objectives of this study were to gather validity evidence for two tools for assessing laparoscopic intracorporeal knot tying and compare the rater-based assessment of laparoscopic intracorporeal suturing with the assessment based on simulator metrics. METHODS Twenty-eight novices and 19 experienced surgeons performed four laparoscopic sutures on a Simball Box simulator twice. Two surgeons used the Intracorporeal Suturing Assessment Tool (ISAT) for blinded video rating. RESULTS Composite Simulator Score (CSS) had higher test-retest reliability than the ISAT. The correlation between the number performed procedures including suturing and ISAT score was 0.51, p<0.001, and 0.59 p<0.001 for CSS. We found an inter-rater reliability (0.72, p<0.001 for test 1 and 0.53 p<0.001 for test 2). The pass/fail rates for ISAT and CSS were similar. CONCLUSION CSS and ISAT provide similar results for assessing laparoscopic suturing but assess different aspects of performance. Using simulator metrics and raters' assessments in combination should be considered for a more comprehensive evaluation of laparoscopic knot-tying competency.

Establishing Methods of Defect Closure in Roux-en-Y Gastric Bypass: an International Survey. Obes Surg 2023; 33:1049-1059. [PMID: 36609742 DOI: 10.1007/s11695-022-06420-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 12/09/2022] [Accepted: 12/14/2022] [Indexed: 01/09/2023]
Abstract
INTRODUCTION Internal herniation (IH) can be a life-threatening complication of Roux-en-Y gastric bypass (RYGB). Randomised controlled trials support the routine closure of mesenteric spaces at RYGB. However, there is currently no consensus on the method of closure in clinical practice. The purpose of this survey is to understand bariatric surgeons' practice in this regard. METHODS We conducted an international survey, whereby questions were created through collaboration of a consensus group of bariatric surgeons and hosted on the SurveyMonkey platform. The survey was distributed among British Obesity and Metabolic Surgery Society (BOMSS) members and international professional channels including The Upper Gastrointestinal Society (TUGS) and social media. RESULTS One hundred and thirty-six surgeons from 34 countries completed the survey. Of these, 49 respondents were UK-based surgeons with a cumulative experience of approximately 2500 RYGB per annum. Forty-five (91.8%) respondents reported always closing mesenteric defects, of whom 57.8% elected to use non-absorbable non-barbed sutures, followed by staples/clips in 28.9% and a selection of other methods. Most respondents used more than one method. A total of 2 UK and 14 non-UK participants reported never closing mesenteric spaces. CONCLUSIONS This survey has shown heterogeneity among defect closure and no consensus on preferred type. Additionally, there remains a practice of non-closure of mesenteric defects. We hope these findings help to inform further needed research and consensus building among experts.

Abstract
Background: Laparoscopic intracorporeal continuous suturing is being employed in a growing number of minimally invasive procedures. However, there is a lack of adequate bench models for gaining proficiency in this complex task. The purpose of this study was to assess a novel simulation model for running suture. Methods: Participants were grouped as novice (LSN) or expert (LSE) at laparoscopic suturing based on prior experience and training level. A novel low-cost bench model was developed to simulate laparoscopic intracorporeal continuous closure of a defect. The primary outcome measured was time taken to complete the task. Videos were scored by independent raters for Global Operative Assessment of Laparoscopic Skills (GOALS). Results: Sixteen subjects (7 LSE and 9 LSN) participated in this study. LSE completed the task significantly faster than LSN (430 ± 107 vs 637 ± 164 seconds, P ≤ .05). LSN scored higher on accuracy penalties than LSE (Median 30 vs 0, P ≤ .05). Mean GOALS score was significantly different between the 2 groups (LSE 20.64 ± 2.64 vs LSN 14.28 ± 1.94, P < .001) with good inter-rater reliability (ICC ≥ .823). An aggregate score using the formula: Performance Score = 1200-time(sec)-(accuracy penalties x 10) was significantly different between groups with a mean score of 741 ± 141 for LSE vs 285 ± 167 for LSN ( P < .001). Conclusion A novel bench model for laparoscopic continuous suturing was able to significantly discriminate between laparoscopic experts and novices. This low-cost model may be useful for both training and assessment of laparoscopic continuous suturing proficiency.

Abstract
BACKGROUND Surgeons have widely adopted endoscopic suturing techniques using conventional laparoscopic instruments and the more advanced robotic systems. The FlexDex is a novel articulating laparoscopic needle driver providing enhanced dexterity in laparoscopic surgery. This study evaluates and compares the learning curve of endoscopic suturing with conventional laparoscopy, the FlexDex and robotic suturing in novices. METHODS Participants performed a minimal invasive suturing task in three different ways in a randomized order: with a conventional laparoscopic needle driver, using the FlexDex needle driver and third, using the Da Vinci Si surgical system. Primary outcome was suturing task time. Secondary outcome parameters were assessment of suturing quality and workload perception. RESULTS A total of 10 novice participants were included and completed a total of 300 sessions. Median (IQR) suturing time of the first 5 sessions was 231 s (188-291) in the laparoscopic group versus 378 s (282-471) in the FlexDex group versus 189 s (160-247) in the DaVinci Si group. The last 5 sessions showed significant reduction of median suturing time of 143 s (120-190), 232 s (180-265) and 172 s (134-199) respectively. Analysis identified that the learning curve for the laparoscopic needle driver and Da Vinci Si was reached in 5 sessions, compared to 8 sessions for the Flexdex. The laparoscopic needle driver and Da Vinci Si showed a significant shorter median suturing time compared to the FlexDex (p = 0.00). The FlexDex quality assessment scores were significantly lower compared to the laparoscopic (p = 0.00) and robotic (p = 0.00) scores and perceived workload remains high for the FlexDex users. CONCLUSIONS Ex vivo endoscopic suturing with the FlexDex demonstrated a prolonged learning curve compared to laparoscopic and robotic suturing. The learning curve of the FlexDex is fundamentally different from conventional laparoscopic and robotic instruments. This study provides further insights in the implementation and training of endoscopic suturing techniques.

Abstract
OBJECTIVE To describe the clinical profile of minimal invasive procedures performed in gynecology at the national referral hospital in Bhutan. A review of such procedures performed in gynecology was needed to assess the baseline information and generate our own experience. We conducted a descriptive study with a review of hospital records of minimal invasive procedures performed from 1st January to 31st December 2020 at the Department of Gynecology. Data were extracted into a structured pro forma. Descriptive statistics were used to express the results. RESULTS The mean age of the patients was 33.9 ± 8.6 years of which the maximum was in the age group 25-34 years. 28 (17.5%) and 132 (82.5%) patients underwent emergency and elective procedures respectively. 142 (88.8%) and 18 (11.2%) patients underwent laparoscopic and hysteroscopic procedures respectively. Ovarian cystectomy was the most commonly performed procedure. The median operating time was 100 min (IQR 62.5-157.5). The overall complication rate was 2.5%. The median postoperative length of hospital stay was 24 h (IQR 3-24). Using our data and experience, we recommend a new health policy to recognize MIS in gynecology as a subspecialty and strengthen the existing service in gynecological MIS.

Development of a simulation curriculum to teach and assess advanced laparoscopic suturing skills using telesimulation: a feasibility study. Surg Endosc 2022; 36:5483-5490. [PMID: 34997338 PMCID: PMC8741533 DOI: 10.1007/s00464-021-08880-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Accepted: 11/16/2021] [Indexed: 11/26/2022]
Abstract
Background Telesimulation helps overcome limitations in time and local expertise by eliminating the need for the learner and educator to be physically co-located, especially important during COVID-19. We investigated whether teaching advanced laparoscopic suturing (ALS) through telesimulation is feasible, effective, and leads to improved suturing in the operating room (OR). Methods In this prospective feasibility study, three previously developed 3D-printed ALS tasks were used: needle handling (NH), suturing under tension (UT), and continuous suturing (CS). General surgery residents (PGY4-5) underwent 1-month of telesimulation training, during which an expert educator at one site remotely trained residents at the other site over 2–3 teaching sessions. Trainees were assessed in the three tasks and in the OR at three time points: baseline(A1), control period(A2), and post-intervention(A3) and completed questionnaires regarding educational value and usability of telesimulation. Paired t-test was used to compare scores between the three assessment points. Results Six residents were included. Scores for UT improved significantly post-intervention A3(568 ± 60) when compared to baseline A1(416 ± 133) (p < 0.019). Similarly, scores for CS improved significantly post-intervention A3(756 ± 113) vs. baseline A1(539 ± 211) (p < 0.02). For intraoperative assessments, scores improved significantly post-intervention A3(21 ± 3) when compared to both A1(17 ± 4) (p < 0.018) and A2(18 ± 4) (p < 0.0008). All residents agreed that tasks were relevant to practice, helped improve technical competence, and adequately measured suturing skill. All residents found telesimulation easy to use, had strong educational value, and want the system to be incorporated into their training. Conclusion The use of telesimulation for remotely training residents using ALS tasks was feasible and effective. Residents found value in training using the tasks and telesimulation system, and improved ALS skills in the OR. As the pandemic has caused a major structural shift in resident education, telesimulation can be an effective alternative to on-site simulation programs. Future research should focus on how telesimulation can be effectively incorporated into training programs.

Abstract
BACKGROUND The benefits of laparoscopic approach for right colectomy have been well established. However, the technical difficulty to construct the intra-corporeal anastomosis is still cumbersome.
AIM To analyze the results of 3D and 2D laparoscopic right colectomy and to compare it to the published series through a systematic review and meta-analysis.
METHODS A retrospective study with propensity score matching analysis of patients undergoing laparoscopic right colectomy at Umbria2 Hospitals from January 2014 to March 2020 was performed. A systematic review was accomplished comparing 2D and 3D right colectomy.
RESULTS In the personal series 47 patients of the 2D group were matched to 47 patients of the 3D group. The 3D group showed a favorable trend in terms of mean operative time (170.7 ± 32.9 min vs 183.8 ± 35.4 min; P = 0.053) and a significant lower anastomotic time (16.9 ± 2.3 min vs 19.6 ± 2.9 min, P < 0.001). The complete mesocolic excision (CME) subgroups analysis showed a shorter anastomotic time (16.5 ± 1.8 min vs 19.9 ± 3.0 min; P < 0.001) and operative time (175.0 ± 38.5 min vs 193.7 ± 37.1 min; P = 0.063) in the 3D group. Six studies and our series were included in the meta-analysis with 551 patients (2D group: 291; 3D group: 260).The pooled analysis demonstrated a significant difference in favour of the 3D group regarding the operative time (P < 0.001) and the anastomotic time (P < 0.001) while no differences were identified between groups in terms of blood loss (P = 0.827), LNH yield (P = 0.243), time to first flatus (P = 0.333), postoperative complications (P = 0.718) and length of stay (P = 0.835).
CONCLUSION The meta-analysis results showed that 3D laparoscopic right colectomy shortens operative and anastomotic time without affecting the standard lymphadenectomy. In our series, the advantage of the 3D system becomes evident when CME and/or more complex associated procedure are requested significantly reducing both the total operative and the anastomotic time.

Abstract
OBJECTIVE To compare the influence of extracorporeal and intracorporeal ligations on the duration of and complications associated with laparoscopic ovariectomy in dogs. STUDY DESIGN Prospective randomized experimental study. ANIMALS Healthy intact female dogs (n = 18). METHODS The left and right ovarian pedicles of dogs undergoing laparoscopic ovariectomy were randomly assigned to intracorporeal (n = 18) or extracorporeal (n = 18) ligation groups. Surgeries were performed by two American College of Veterinary Surgeons (ACVS) diplomates and two ACVS residents. The time required to place extracorporeal and intracorporeal ligations, duration of surgery, and intraoperative complications were compared between ligation techniques. Postoperative complications were recorded. RESULTS The time required for intracorporeal ligation (17.3 ± 8.7 minutes) did not differ from that required for extracorporeal ligation (15.1 ± 6.1 minutes; P = .38). The total duration of surgery was 102.7 ± 28.7 minutes including portal placement and veterinary student closure of incisions. Ligation of the ovarian pedicle was successful in 16 of 17 dogs. Intraoperative hemorrhage occurred in three dogs, and postoperative complications were noted in three dogs, without apparent difference between ligation techniques. CONCLUSION No difference was identified between extracorporeal and intracorporeal ligations of ovarian pedicles. CLINICAL SIGNIFICANCE This study does not provide evidence to support one ligation technique rather than the other.

The effect of preferred music on mental workload and laparoscopic surgical performance in a simulated setting (OPTIMISE): a randomized controlled crossover study. Surg Endosc 2020; 35:5051-5061. [PMID: 33026515 PMCID: PMC8346395 DOI: 10.1007/s00464-020-07987-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Accepted: 09/14/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND Worldwide, music is commonly played in the operation room. The effect of music on surgical performance reportedly has varying results, while its effect on mental workload and key surgical stressor domains has only sparingly been investigated. Therefore, the aim is to assess the effect of recorded preferred music versus operating room noise on laparoscopic task performance and mental workload in a simulated setting. METHODS A four-sequence, four-period, two-treatment, randomized controlled crossover study design was used. Medical students, novices to laparoscopy, were eligible for inclusion. Participants were randomly allocated to one of four sequences, which decided the exposure order to music and operation room noise during the four periods. Laparoscopic task performance was assessed through motion analysis with a laparoscopic box simulator. Each period consisted of ten alternating peg transfer tasks. To account for the learning curve, a preparation phase was employed. Mental workload was assessed using the Surgery Task Load Index. This study was registered with the Netherlands Trial Register (NL7961). RESULTS From October 29, 2019 until March 12, 2020, 107 participants completed the study, with 97 included for analyzation. Laparoscopic task performance increased significantly during the preparation phase. No significant beneficial effect of music versus operating room noise was observed on time to task completion, path length, speed, or motion smoothness. Music significantly decreased mental workload, reflected by a lower score of the total weighted Surgery Task Load Index in all but one of the six workload dimensions. CONCLUSION Music significantly reduced mental workload overall and of several previously identified key surgical stressor domains, and its use in the operating room is reportedly viewed favorably. Music did not significantly improve laparoscopic task performance of novice laparoscopists in a simulated setting. Although varying results have been reported previously, it seems that surgical experience and task demand are more determinative.

Application of Laparoscopic Radical Resection for Type III and IV Hilar Cholangiocarcinoma Treatment. Gastroenterol Res Pract 2020; 2020:1506275. [PMID: 32184814 PMCID: PMC7060852 DOI: 10.1155/2020/1506275] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 12/26/2019] [Indexed: 02/07/2023] Open
Abstract
Background This study is aimed at investigating the feasibility and safety of the laparoscopic radical resection for treating type III and IV hilar cholangiocarcinoma (III/IV Hilar C). Methods Six patients with III/IV Hilar C were enrolled in our hospital. All patients underwent total laparoscopic surgery, including basic surgery (laparoscopic gallbladder, hilar bile duct, and common bile duct resection and hepatoduodenal ligament lymph node dissection) combined with left hepatic and caudate lobe resection/portal resection. The tumor size, operation time, intraoperative blood loss, and postoperative complications were observed. The follow-up of the patients after discharge was recorded. Results Surgery was successfully completed in 6 patients. We found that the tumor size of 6 patients ranged from 1.5 to 3.6 cm, with 4 lymph nodes. The operation time was 540-660 minutes, and the blood loss was 300-500 ml. One patient developed bile leakage after surgery, healed within 2 weeks after drainage. The postoperative hospital stay was 16 (13-24) days. There were 4 cases of negative bile duct margin tumor, 1 case was positive, and 1 case was not reported. All 6 patients were discharged smoothly without perioperative death. Regular examinations were conducted every 3 months after discharge, and the median duration was 7 months. Only 1 patient had a marginal dysplasia, and 5 patients had no obvious signs of recurrence. Conclusions Application of laparoscopic radical resection for III/IV Hilar C is safe and feasible and has good short-term efficacy with adequate preoperative evaluation, appropriate case selection, and precise operative strategy.

Novel application of the sewing machine principle; a new simplified intracorporeal suturing technique for pediatric inguinal hernia. J Pediatr Surg 2019; 54:1505-1509. [PMID: 30827487 DOI: 10.1016/j.jpedsurg.2019.01.054] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 01/14/2019] [Accepted: 01/19/2019] [Indexed: 11/29/2022]
Abstract
BACKGROUND The desire of pediatric surgeon to reduce incision related morbidity and pain while achieving good cosmetic results has recently led to the introduction of single incision pediatric endosurgery [SIPES] and needlescopic surgery. Intracorporeal suturing and knot tying during SIPES remain challenging. The aim of this study is to introduce a novel and simple technique for intracorporeal suturing of the pediatric inguinal hernia after needlescopic disconnection of hernia sac using just needles rather than laparoscopic instruments. It is an imitation of the principles of sewing machine. METHODS The first author discussed the idea of the technique with the coauthors and a demonstration was done on a Silicon Pad before application of the technique on children with congenital inguinal hernia [CIH] for peritoneum closure after needlescopic disconnection of the hernia sac. The main outcome measures were feasibility of the technique, suturing and knotting time and recurrence rate. RESULTS The sutures were snugly applied to the ridges of Silicon Pad with good approximation and the knot was firmly tightened in all experiments. After applying and mastering the technique on a Silicon Pad, we shifted to use it on 373 children with 491 hernia defects. All operations were completed by the needlescopic technique without the need for insertion of any laparoscopic instruments. The time required for suturing of the peritoneum around internal inguinal ring [IIR] and knot tying, decreased considerably from 6 min 27 s in the first operation to less than 4 min after the fifth operation and stabilized at approximately 4 min 30 s. No major intraoperative complication. There was no recurrence during a mean follow-up period of 19.6 ± 1.2 months. CONCLUSION The closure of the peritoneum around the IIR using needles mimicking what is happening in sewing machine suturing is a feasible, safe and effective line of treatment of children with CIH. The cosmetic results are 42 outstanding without any recurrence.

Abstract
BACKGROUND Fundoplication, was first introduced as a surgical treatment method of gastroesophageal reflux disease. Consequently, several modifications of this method have been described, whereas laparoscopic fundoplication was recently introduced. Although single incision (SI) fundoplication was considered as an alternative to the conventional laparoscopic approach, several studies reported an increased operation duration, and high rates of multiport conversion and incisional hernia.
AIM To provide a current overview of the technical variations and the postoperative outcomes of patients submitted to SI fundoplication.
METHODS The present systematic review of the literature was designed and conducted on the basis of the PRISMA guidelines. A systematic screening of the electronic scholar databases (Medline, Scopus and Web of Science) was performed.
RESULTS Literature search resulted in the identification of 19 studies. Overall, 266, 137 and 110 SI Nissen, Dor and Toupet fundoplications were reported, respectively. In the majority of the trials, standard laparoscopic instruments were used. The left liver lobe was displayed through the use of forceps, graspers, retractors, drains or even glue. Both intra-corporeal and extracorporeal suturing was described. Mean operative time was 136.3 min. Overall complication rate was 5.2% and the rate of incisional hernia was 0.9%. No mortality was reported.
CONCLUSION Due to the methodological heterogeneity and the lack of high quality studies comparing multi to single access techniques and the several variations, we conclude that further well designed studies are necessary, in order to evaluate the role of SI fundoplication.

Abstract
Surgical adhesives are an attractive alternative to traditional mechanical tissue fixation methods of sutures and staples. Ease of application, biocompatibility, enhanced functionality (drug delivery) are known advantages but weak adhesion strength in the wet environment and lack of tissue compliant behavior still pose a challenge. In order to address these issues, non-aqueous bioadhesive based on blends of polyamidoamine (PAMAM) dendrimer, conjugated with 4-[3-(trifluoromethyl)-3H-diazirin-3-yl] benzyl bromide (PAMAM-g-diazirine) and liquid polyethylene glycol (PEG 400) has been developed. PEG 400 biocompatible solvent reduces the viscosity of PAMAM-g-diazirine dendrimer without incorporating aqueous solvents or plasticizers, allowing application by syringe or spray. Upon UV activation, diazirine-generated reactive intermediates lead to intermolecular dendrimer crosslinking. The properties of the crosslinked matrix are tissue compliant, with anisotropic material properties dependent on the PEG 400 wt%, UV dose, pressure and uncured adhesive thickness. The hygroscopic PAMAM-g-diazirine/PEG 400 blend was hypothesized to absorb water at the tissue interface, leading to high interfacial adhesion, however porous matrices led to cohesive failure. The hydrophilic nature of the polyether backbone (PEG 400) shielded cationic PAMAM dendrimers with cured bioadhesive film displaying significantly less platelet activation than neat PAMAM-g-diazirine or PLGA thin films.

Abstract
BACKGROUND The use of 3D laparoscopic systems is expanding. The European Association of Endoscopic Surgery (EAES) initiated a consensus development conference with the aim of creating evidence-based statements and recommendations for the surgical community. METHODS Systematic reviews of the PubMed and Embase libraries were performed to identify evidence on potential benefits of 3D on clinical practice and patient outcomes. Statements and recommendations were prepared and unanimously agreed by an international surgical and engineering expert panel which were presented and voted at the EAES annual congress, London, May 2018. RESULTS 9967 abstracts were screened with 138 articles included. 18 statements and two recommendations were generated and approved. 3D significantly shortened operative time (mean difference 11 min (8% [95% CI 20.29-1.72], I2 96%)). A significant reduction in complications was observed when 3D systems were used (RR 0.75, [95 CI% 0.60-0.94], I2 0%) particularly for cases involving laparoscopic suturing (RR 0.57 [95% CI 0.35-0.90], I2 0%). In 69 box trainer or simulator studies, 64% concluded trainees were significant faster and 62% performed fewer errors when using 3D. CONCLUSION We recommend the use of 3D vision in laparoscopy to reduce the operative time (grade of recommendation: low). Future robust clinical research is required to specifically investigate the potential benefit of 3D laparoscopy system on complication rates (grade of recommendation: high).

Validation of a virtual intracorporeal suturing simulator. Surg Endosc 2018; 33:2468-2472. [PMID: 30334151 DOI: 10.1007/s00464-018-6531-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2018] [Accepted: 10/11/2018] [Indexed: 01/22/2023]
Abstract
BACKGROUND Intracorporeal suturing is one of the most important and difficult procedures in laparoscopic surgery. Practicing on a FLS trainer box is effective but requires large number of consumables, and the scoring is somewhat subjective and not immediate. A virtualbasic laparoscopic skill trainer (VBLaST©) was developed to simulate the five tasks of the FLS Trainer Box. The purpose of this study is to evaluate the face and content validity of the VBLaST suturing simulator (VBLaST-SS©). METHODS Twenty-five medical students and residents completed an evaluation of the simulator. The participants were asked to perform the standard intracorporeal suturing task on both VBLaST-SS© and the traditional FLS box trainer. The performance scores on each system were calculated based on time (s), deviations to the black dots (mm), and incision gap (mm). The participants were then asked to finish a 13-item questionnaire with ratings from 1 (not realistic/useful) to 5 (very realistic/useful) regarding the face validity of the simulator. A Wilcoxon signed rank test was performed to identify differences in performance on the VBLaST-SS© compared to that of the traditional FLS box trainer. RESULTS Three questions from the face validity questionnaire were excluded due to lack of response. Ratings to 8 of the remaining 10 questions (80%) averaged above 3.0 out of 5. Average intracorporeal suturing completion time on the VBLaST-SS© was 421 (SD = 168 s) seconds compared to 406 (175 s) seconds on the box trainer (p = 0.620). There was a significant difference between systems for the incision gap (p = 0.048). Deviation in needle insertion from the black dot was smaller for the box trainer than the virtual simulator (1.68 vs. 7.12, p < 0.001). CONCLUSION Participants showed comparable performance on the VBLaST-SS© and traditional box trainer. Overall, the VBLaST-SS© system showed face validity and has the potential to support training for the suturing skills.
