Assessing the stops framework for coping with intraoperative errors: Evidence of efficacy, hints of hubris, and a bridge to abridging burnout.

BACKGROUND: Answering calls in the literature, we developed and introduced an evidence-based tool for surgeons facing errors in the operating room: the STOPS framework (stop, talk to you team, obtain help, plan, succeed). The purpose of this research was to assess the impact of presenting this psychological tool on resident coping in the operating room and the related outcome of burnout while examining sex differences. METHODS: In a natural experiment, general surgery residents were invited to attend 2 separate educational conferences regarding coping with errors in the operating room. Three months later, all residents were asked to fill out a survey assessing their coping in the operating room, level of burnout, and demographics. We assessed the impact of the educational intervention by comparing those who attended the coping conferences with those who did not attend. RESULTS: Thirty-five residents responded to the survey (65% response rate, 54% female respondents, 49% junior residents). Our hypothesized moderated mediation model was supported. Sex was found to moderate the impact of the STOPS framework-female residents who attended the coping educational conference reported higher coping self-efficacy, whereas attendance had no statistically significant impact on male levels of coping self-efficacy. In turn, higher coping self-efficacy was associated with lower levels of burnout. CONCLUSION: Our results suggest that there is evidence of efficacy in this instruction-female residents presented this material report higher levels of coping in the operating room compared to those who did not receive the framework. Further, increase in coping ability was associated with reduced levels of burnout for both genders.

Exploration of Patient Retention in Seeking a Second Opinion: A Retrospective Cohort Study.

INTRODUCTION: It is common for cancer patients to seek a second opinion for a variety of reasons. Understanding what drives patients to choose to receive treatment with their second opinion provider may uncover opportunities to improve the second opinion process. Therefore, we sought to identify the patient, disease, and treatment characteristics that were associated with second opinion retention rates in patients seeking a second surgical opinion for breast, colon, and pancreatic cancer. METHODS: We conducted a retrospective cohort study to evaluate patients who sought a second opinion within a large academic health-care system for breast, colon, and pancreatic cancer. Electronic medical records were reviewed for second opinions. Patient demographics and characteristics were collected and compared between the retained group and the nonretained groups. RESULTS: A total of 237 patients obtained second opinions for breast, colorectal, and pancreatic cancer. Patients that were offered a different treatment plan at their second opinion were more likely to be retained for systemic therapy (P = 0.009) for pancreatic cancer and any treatment for colon cancer (P = 0.003). Seeing a radiation oncologist (P = 0.007) or a plastic surgeon (P = 0.02) during the multidisciplinary consultation increased retention rates for breast cancer. CONCLUSIONS: Surgeons can better identify patients that are more likely to be retained after a second opinion by the individual patient characteristics and treatment factors. Understanding the factors that lead to retention for these three cancer types may help physicians provide the best possible resources for most patients presenting for second opinion evaluations.

Robotic-assisted reoperative ileal pouch-anal anastomosis: robotic pouch excision and pouch revision.

BACKGROUND: Up to 20% of patients with ileal pouch will develop pouch failure, ultimately requiring surgical reintervention. As a result of the complexity of reoperative pouch surgery, minimally invasive approaches were rarely utilized. In this series, we present the outcomes of the patients who underwent robotic-assisted pouch revision or excision to assess its feasibility and short-term results. METHODS: All the patients affected by inflammatory bowel diseases and familial adenomatous polyposis who underwent robotic reoperative surgery of an existing ileal pouch were included. RESULTS: Twenty-two patients were included; 54.6% were female. The average age at reoperation was 51 ± 16 years, with a mean body mass index of 26.1 ± 5.6 kg/m2. Fourteen (63.7%) had a diagnosis of ulcerative colitis at reoperation, and seven (31.8%) had Crohn's disease. The mean time to pouch reoperation was 12.8 ± 11.8 years. Seventeen (77.3%) patients underwent pouch excision, and five (22.7%) had pouch revision surgery. The mean operative time was 372 ± 131 min, and the estimated blood loss was 199 ± 196.7 ml. The conversion rate was 9.1%, the 30-day morbidity rate was 27.3% (with only one complication reaching Clavien-Dindo grade IIIB), and the mean length of stay was 5.8 ± 3.9 days. The readmission rate was 18.2%, the reoperation rate was 4.6%, and mortality was nihil. All patients in the pouch revisional group are stoma-free. CONCLUSION: Robotic reoperative pouch surgery in highly selected patients is technically feasible with acceptable outcomes.

Effect of previous abdominal surgery on robotic-assisted rectal cancer surgery.

BACKGROUND: The effect of previous abdominal surgery (PAS) in laparoscopic surgery is well known and significantly adds to longer hospital length of stay (LOS), postoperative ileus, and inadvertent enterotomies. However, little evidence exists in patients with PAS undergoing robotic-assisted (RA) rectal surgery. METHODS: All patients undergoing RA surgery for rectal cancer were reviewed. Patients with PAS were divided into minor and major PAS groups, defined as surgery involving >1 quadrant. The primary outcome was the risk of conversion to open surgery. RESULTS: A total of 750 patients were included, 531 in the no-PAS (NPAS) group, 31 in the major PAS group, and 188 in the minor PAS group. Patients in the major PAS group had significantly longer hospital LOS (P < .001) and lower adherence to enhanced recovery pathways (ERPs; P = .004). The conversion rates to open surgery were similar: 3.4% in the NPAS group, 5.9% in the minor PAS group, and 9.7% in the major PAS group (P = .113). Estimated blood loss (EBL; P = .961), operative times (OTs; P = .062), complication rates (P = .162), 30-day readmission (P = .691), and 30-day mortality (P = .494) were similar. Of note, 53 patients underwent lysis of adhesions (LOA). On multivariate analysis, EBL >500 mL and LOA significantly influenced conversion to open surgery. EBL >500 mL, age >65 years, conversion to open surgery, and prolonged OT were risk factors for prolonged LOS, whereas adherence to ERPs was a protector. CONCLUSION: PAS did not seem to affect the outcomes in RA rectal surgery. Given this finding, the robotic approach may ultimately provide patients with PAS with similar risk to patients without PAS.

Evolution of laparoscopic ileal pouch-anal anastomosis: impact of enhanced recovery program, medication changes, and staged approaches on outcomes.

BACKGROUND: Although laparoscopic Ileal pouch-anal anastomosis (IPAA) has become the gold standard in restorative proctocolectomy, surgical techniques have experienced minimal changes. In contrast, substantial shifts in perioperative care, marked by the enhanced recovery program (ERP), modifications in steroid use, and a shift to a 3-staged approach, have taken center stage. METHODS: Data extracted from our prospective IPAA database focused on the first 100 laparoscopic IPAA cases (historic group) and the latest 100 cases (modern group), aiming to measure the effect of these evolutions on postoperative outcomes. RESULTS: The historic IPAA group had more 2-staged procedures (92% proctocolectomy), whereas the modern group had a higher number of 3-staged procedures (86% proctectomy) (P < .001). Compared with patients in the modern group, patients in the historic group were more likely to be on steroids (5% vs 67%, respectively; P < .001) or immunomodulators (0% vs 31%, respectively; P < .001) at surgery. Compared with the historic group, the modern group had a shorter operative time (335.5 ± 78.4 vs 233.8 ± 81.6, respectively; P < .001) and length of stay (LOS; 5.4 ± 3.1 vs 4.2 ± 1.6 days, respectively; P < .001). Compared with the modern group, the historic group exhibited a higher 30-day morbidity rate (20% vs 33%, respectively; P = .04) and an elevated 30-day readmission rate (9% vs 21%, respectively; P = .02). Preoperative steroids use increased complications (odds ratio [OR], 3.4; P = .01), whereas 3-staged IPAA reduced complications (OR, 0.3; P = .03). ERP was identified as a factor that predicted shorter stays. CONCLUSION: Although ERP effectively reduced the LOS in IPAA surgery, it failed to reduce complications. Conversely, adopting a 3-staged IPAA approach proved beneficial in reducing morbidity, whereas preoperative steroid use increased complications.

Implementation of a Brief Evidence-Based Intraoperative Coping Curriculum.

BACKGROUND AND RATIONALE: Recent research has called for further resident training in coping with errors and adverse events in the operating room. To the best of our knowledge, there currently exists no evidence-based curriculum or training on this topic. MATERIALS AND METHODS: Synthesizing three prior studies on how experienced surgeons react to errors and adverse events, we developed the STOPS framework for handling surgical errors and adverse events (Stop, Talk to your team, Obtain help, Plan, Succeed). This material was presented to residents in two teaching sessions. RESULTS AND CONCLUSION: In this paper, we describe the presentation of, and the uniformly positive resident reaction to, the STOPS framework: an empirically based psychological tool for surgeons who experience operative errors or adverse events.

Scrubbing With Aristotle: Cultivating Surgical Wisdom through Inflection Points.

Surgical educators and researchers have well-considered a breadth of topics related to surgery. However, there is one concept that is notably absent in this corpus: surgical wisdom. In this perspective, we draw on work from Aristotle and psychology research to introduce the concept of phronesis, which we believe is useful for understanding surgical wisdom. We further illustrate how this concept can be a useful tool for surgical educators through the discussion of four distinct functions of phronesis, and illustrating the ability of these functions to help learners cultivate knowledge at important decision points, or inflection points, in surgical training and a surgical career.

The good, the bad, and the ugly: Operative staff perspectives of surgeon coping with intraoperative errors.

BACKGROUND: Intraoperative errors are inevitable, and how surgeons respond impacts patient outcomes. Although previous research has queried surgeons on their responses to errors, no research to our knowledge has considered how surgeons respond to operative errors from a contemporary first-hand source: the operating room staff. This study evaluated how surgeons react to intraoperative errors and the effectiveness of employed strategies as witnessed by operating room staff. METHODS: A survey was distributed to operating room staff at 4 academic hospitals. Items included multiple-choice and open-ended questions assessing surgeon behaviors observed after intraoperative error. Participants reported the perceived effectiveness of the surgeon's actions. RESULTS: Of 294 respondents, 234 (79.6%) reported being in the operating room when an error or adverse event occurred. Strategies positively associated with effective surgeon coping included the surgeon telling the team about the event and announcing a plan. Themes emerged regarding the importance of the surgeon remaining calm, communicating, and not blaming others for the error. Evidence of poor coping also emerged: "Yelling, feet stomping and throwing objects onto the field. [The surgeon] cannot articulate needs well because of anger." CONCLUSION: These data from operating room staff corroborates previous research presenting a framework for effective coping while shedding light on new, often poor, behaviors that have not emerged in prior research. Surgical trainees will benefit from the now-enhanced empirical foundation on which coping curricula and interventions can be built.

Using hand pose estimation to automate open surgery training feedback.

PURPOSE: This research aims to facilitate the use of state-of-the-art computer vision algorithms for the automated training of surgeons and the analysis of surgical footage. By estimating 2D hand poses, we model the movement of the practitioner's hands, and their interaction with surgical instruments, to study their potential benefit for surgical training. METHODS: We leverage pre-trained models on a publicly available hands dataset to create our own in-house dataset of 100 open surgery simulation videos with 2D hand poses. We also assess the ability of pose estimations to segment surgical videos into gestures and tool-usage segments and compare them to kinematic sensors and I3D features. Furthermore, we introduce 6 novel surgical dexterity proxies stemming from domain experts' training advice, all of which our framework can automatically detect given raw video footage. RESULTS: State-of-the-art gesture segmentation accuracy of 88.35% on the open surgery simulation dataset is achieved with the fusion of 2D poses and I3D features from multiple angles. The introduced surgical skill proxies presented significant differences for novices compared to experts and produced actionable feedback for improvement. CONCLUSION: This research demonstrates the benefit of pose estimations for open surgery by analyzing their effectiveness in gesture segmentation and skill assessment. Gesture segmentation using pose estimations achieved comparable results to physical sensors while being remote and markerless. Surgical dexterity proxies that rely on pose estimation proved they can be used to work toward automated training feedback. We hope our findings encourage additional collaboration on novel skill proxies to make surgical training more efficient.

Robotic Redo Ileocolonic Resection for Crohn's Disease: A Preliminary Report From a Tertiary Care Center.

BACKGROUND: Although the safety of laparoscopic redo ileocolonic resection for Crohn's disease has been described before, the safety of robotic redo ileocolonic resection is still unelucidated. OBJECTIVE: This study aimed to share our preliminary experience regarding the safety of robotic redo ileocolonic resection for Crohn's disease. DESIGN: Retrospective analysis. SETTING: Tertiary care center. PATIENTS: All consecutive adult patients who underwent robotic ileocolonic resection for Crohn's disease at our institution between 2014 and 2021 were included. Patients were divided into redo ileocolonic resection and primary ileocolonic resection groups. PRIMARY OUTCOME MEASURES: Baseline demographics, preoperative risk factors, and intraoperative details were compared between both groups. The primary outcome was conversion to an open approach, and secondary outcomes were 30-day postoperative complications. RESULTS: A total of 98 patients were included. Of them, 18 (18.4%) had a redo ileocolonic resection. Patients who had a redo ileocolonic resection were more likely to have a longer duration of disease, associated anoperineal disease, a higher number of previous lines of medical treatments, received total parental nutrition before the operation for correction of malnutrition, and longer time for adhesiolysis. Patients who had redo ileocolonic resection had a higher risk for conversion to open ileocolonic resection [3 (16.7%) versus 2 (2.5%); p value = 0.04]. There was no statistically significant difference regarding the overall length of stay and the 30-day morbidity between both groups. No 30-day mortality or anastomotic leaks occurred in either group. LIMITATIONS: Retrospective nature of the analysis. CONCLUSIONS: Robotic redo ileocolonic resection showed similar short-term postoperative outcomes to robotic primary ileocolonic resection for Crohn's disease. However, conversion rates are higher in robotic redo ileocolonic resection yet seem lower than previously published results in laparoscopic surgery.

RESECCIN ILEOCLICA ROBTICA REDO PARA LA ENFERMEDAD DE CROHN INFORME PRELIMINAR DE UN CENTRO DE ATENCIN TERCIARIA: ANTECEDENTES:Si bien la seguridad de la resección ileocolónica laparoscópica para la enfermedad de Crohn se ha descrito antes, la seguridad de la resección ileocolónica robótica aún no se ha dilucidado.OBJETIVO:Este estudio tuvo como objetivo compartir nuestra experiencia preliminar con respecto a la seguridad de la resección ileocolónica robótica para la enfermedad de Crohn.DISEÑO:Análisis retrospectivo.AJUSTE:Centro de atención terciaria.PACIENTES:Se incluyeron todos los pacientes adultos consecutivos que se sometieron a resección ileocolónica robótica por enfermedad de Crohn en nuestra institución entre 2014 y 2021. Los pacientes se dividieron en grupos de resección ileocolónica reconfeccionada y resección ileocolónica primaria.MEDIDAS DE RESULTADO:Se compararon los datos demográficos iniciales, los factores de riesgo preoperatorios y los detalles intraoperatorios entre ambos grupos. El resultado primario fue la conversión a abierto y los resultados secundarios fueron las complicaciones posoperatorias a los treinta días.RESULTADOS:Se incluyeron un total de 98 pacientes. De ellos, 18 (18,4%) tuvieron resección ileocolónica. Los pacientes que se sometieron a una nueva resección ileocolónica tenían más probabilidades de tener una mayor duración de la enfermedad, enfermedad anoperineal asociada, un mayor número de líneas previas de tratamientos médicos, más probabilidades de haber recibido nutrición parental total antes de la operación para la corrección de la desnutrición y más tiempo tiempo de adhesiolisis. Los pacientes que se sometieron a una nueva resección ileocolónica tuvieron un mayor riesgo de conversión a cirugía abierta [3 (16,7 %) frente a 2 (2,5 %); valor p 0,04]. No hubo diferencia estadísticamente significativa con respecto a la duración total de la estancia y la morbilidad a los treinta días entre ambos grupos. No hubo mortalidad a los treinta días ni fugas anastomóticas en ninguno de los grupos.LIMITACIONES:Naturaleza retrospectiva del análisis.CONCLUSIÓN:La resección ileocolónica robótica mostró resultados postoperatorios a corto plazo similares a la resección ileocolónica primaria robótica para la enfermedad de Crohn. Sin embargo, las tasas de conversión son más altas en la resección ileocolónica robótica, pero parecen más bajas que los resultados publicados previamente en la cirugía laparoscópica.

STOPS: A Coping Framework for Surgeons Who Experience Intraoperative Error.

OBJECTIVE: To investigate the steps faculty surgeons take upon experiencing intraoperative error and synthesize these actions to offer a framework for coping with errors. BACKGROUND: While intraoperative errors are inevitable, formal training in error recovery is insufficient and there are no established curricula that teach surgeons how to deal with the intraoperative error. This is problematic because insufficient error recovery is detrimental to both patient outcomes and surgeon psychological well-being. METHODS: We conducted a thematic analysis. One-hour in-depth semistructured interviews were conducted with faculty surgeons from 3 hospitals. Surgeons described recent experiences with intraoperative error. Interviews were transcribed and coded. Analysis allowed for development of themes regarding responses to errors and coping strategies. RESULTS: Twenty-seven surgeons (30% female) participated. Upon completion of the analysis, themes emerged in 3 distinct areas: (1) Exigency, or a need for training surgical learners how to cope with intraoperative errors, (2) Learning, or how faculty surgeons themselves learned to cope with intraoperative errors, and (3) Responses, or how surgeons now handle intraoperative errors. The latter category was organized into the STOPS framework: Intraoperative errors could produce STOPS: Stop, Talk to your Team, Obtain Help, Plan, Succeed. CONCLUSIONS AND RELEVANCE: This study provides both novel insight into how surgeons cope with intraoperative errors and a framework that may be of great use to trainees and faculty alike.

Acute social isolation and postoperative surgical outcomes. Lessons learned from COVID-19 pandemic.

BACKGROUND: During COVID-19 pandemic, hospitals changed visitation policy to limit the infection spread. We aimed to evaluate the impact of evolving visitation policy on short-term surgical outcomes. METHODS: All adult patients who underwent colorectal surgery between January 1st, 2020, and May 12th, 2020, at our institution were included. Patients were divided into: before implementing the no visitor allowed policy (VA) or no visitor allowed policy (NVA) groups, based on the hospital admission date.. The primary outcomes were 30-day readmission rate and length of stay (LOS). RESULTS: A total of 439 patients were included. Of them, 128 (29.2%) patients had surgery during the NVA policy, and 311 (70.8%) patients underwent surgery during VA policy. Patients who had surgery during the NVA policy were more likely to have emergency surgery and a longer operation time. However, the other baseline characteristics, surgical approach, underlying disease, extent of resection, and the need for intraoperative blood transfusion were comparable between the two groups. There was no difference between both groups regarding the 30-day readmission rate (10.3% vs. 7.8% in the NVA group; P>0.05) and median LOS (4 days vs. 3 days in the NVA group; P>0.05). CONCLUSIONS: Restricting inpatient visitors for patients undergoing colorectal surgery was not associated with increased postoperative complications and readmission rates. LOS was similar between the two groups. This strategy can be safely implemented in cases of crisis. Further studies are needed to confirm these findings.

Revealing hidden experiences: Gendered microaggressions and surgical faculty burnout.

BACKGROUND: Studies report higher burnout in women faculty surgeons compared to men. However, few studies have examined underlying mechanisms for these gendered differences. Gendered differences in microaggression experiences may explain part of the relationship between gender and burnout. We aimed to investigate the relationship between gender, gendered microaggressions, and burnout and test the hypothesis that microaggressions contribute to the relationship between gender and burnout. METHODS: In this 2021 study, a survey was distributed to surgical faculty at 7 institutions. Variables included gender identity, race, average hours worked recently, the Oldenburg Burnout Inventory, and a modified Racial and Ethnic Microaggressions Scale to assess gendered microaggressions. To assess the relationship between surgical faculty gender and burnout, and if this relationship could be explained by microaggressions, a mediation model was tested. RESULTS: A total of 109 participants (40% female) completed the survey and were included in analysis. The hypothesized indirect effect of gender on burnout (M = 2.70/5, SD = 0.81), through gender-based microaggressions (M = 1.7/5, SD = 1.9), was significant, B = -0.25, SE B = 0.09, confidence interval (-0.44 to -0.09): women surgeons reported higher levels of gendered microaggressions, which predicted higher levels of burnout. The overall model was significant (R2 = .16, F[6,102] = 3.33, P < .01). Race, specialty, hours worked, and years of experience were all not significant in the model. CONCLUSION: Gendered microaggressions mediate the relationship between gender and burnout, providing a potential mechanism for the higher rates of burnout in women surgeons evident in prior research. These multi-institutional data provide a focus for targeted initiatives that could decrease both burnout rates and the impact of gender bias on surgical faculty.

With a Little Help From My Friends: The Negating Impact of Social Community and Mentorship on Burnout.

INTRODUCTION: Physician burnout has been demonstrated at high rates among surgeons. Research has shown that physicians experiencing burnout have higher rates of depression, substance abuse, attrition, and medical errors. Surgical culture often promotes self-reliance; however, lacking social connections may worsen burnout. Therefore, we aimed to determine if struggling to develop a professional or personal community is associated with worsened burnout in surgeons. METHODS: We conducted a survey of surgical residents and faculty at seven institutions in the United States in the spring of 2021. Variables measured included mentorship experience, presence of a social community outside work, burnout levels (Professional Fulfillment Index [PFI], 15: high professional fulfillment, 75: low professional fulfillment), average weekly hours worked over the previous 2 mo, and demographics (race, gender, and role: faculty or resident). RESULTS: A total of 218 participants completed the survey (50% residents and 54% male). Participants' PFI scores were an average of 36.29/75, indicating poor professional fulfillment (standard deviation [SD] = 11.80). A multiple linear regression revealed that struggling to find a mentor (ß = 0.20, P = 0.004) and not having a social community exterior to the hospital (ß = -0.25, P < 0.001) were independently associated with significantly higher PFI scores (P < 0.001, R2 = 0.13). Gender, race, role, and hours worked were not associated with the PFI score. CONCLUSIONS: Struggling to find a mentor and a lack of social community outside of work are associated with higher levels of burnout in this multi-institutional study. These findings suggest that targeting an improved support for building professional and personal relationships may be a strategy for improving burnout levels in both faculty and resident surgeons.

Intraoperative Fluid Management a Modifiable Risk Factor for Surgical Quality - Improving Standardized Practice.

OBJECTIVE: We aimed to determine a safe zone of intraoperative fluid management associated with the lowest postoperative complication rates without increased acute kidney injury (AKi) risk for elective colorectal surgery patients. BACKGROUND: To date, standard practice within institutions, let alone national expectations related to fluid administration, are limited. This fact has perpetuated a quality gap. METHODS: Elective colorectal surgeries between 2018 and 2020 were included. Unadjusted odds ratios (ORs) for postoperative ileus, prolonged LOS, and AKi were plotted against the rate of intraoperative RL infusion (mL/ kg/h) and total intraoperative volume. Binary logistic regression analysis, including fluid volumes as a confounder, was used to identify risk factors for postoperative complications. RESULTS: A total of 2900 patients were identified. Of them, 503 (17.3%) patients had ileus, 772 (26.6%) patients had prolonged LOS, and 240 (8.3%) patients had AKI. The intraoperative fluid resuscitation rate (mg/kg/h) was less impactful on postoperative ileus, LOS, and AKI than the total amount of intraoperative fluid. A total fluid administration range between 300 mL and 2.7 L was associated with the lowest complication rate. Total intraoperative RL ≥2.7 L was independently associated with a higher risk of ileus (adjusted OR 1.465; 95% confidence interval 1.154-1.858) and prolonged LOS (adjusted OR 1.300; 95% confidence interval 1.047-1.613), but not AKI. Intraoperative RL ≤300 mL was not associated with an increased risk of AKI. CONCLUSION: Total intraoperative RL ≥2.7 L was independently associated with postoperative ileus and prolonged LOS in elective colorectal surgery patients. A new potential standard for intraoperative fluids will require anesthesia case planning (complexity and duration) to ensure total fluid volume meets this new opportunity to improve care.

Video-based fully automatic assessment of open surgery suturing skills.

PURPOSE: The goal of this study was to develop a new reliable open surgery suturing simulation system for training medical students in situations where resources are limited or in the domestic setup. Namely, we developed an algorithm for tools and hands localization as well as identifying the interactions between them based on simple webcam video data, calculating motion metrics for assessment of surgical skill. METHODS: Twenty-five participants performed multiple suturing tasks using our simulator. The YOLO network was modified to a multi-task network for the purpose of tool localization and tool-hand interaction detection. This was accomplished by splitting the YOLO detection heads so that they supported both tasks with minimal addition to computer run-time. Furthermore, based on the outcome of the system, motion metrics were calculated. These metrics included traditional metrics such as time and path length as well as new metrics assessing the technique participants use for holding the tools. RESULTS: The dual-task network performance was similar to that of two networks, while computational load was only slightly bigger than one network. In addition, the motion metrics showed significant differences between experts and novices. CONCLUSION: While video capture is an essential part of minimal invasive surgery, it is not an integral component of open surgery. Thus, new algorithms, focusing on the unique challenges open surgery videos present, are required. In this study, a dual-task network was developed to solve both a localization task and a hand-tool interaction task. The dual network may be easily expanded to a multi-task network, which may be useful for images with multiple layers and for evaluating the interaction between these different layers.
