The use of advanced robotic simulation labs to advance and assess senior resident robotic skills and operating room leadership competency: a pilot study.

BACKGROUND: General surgery has the fastest growing robotic operative volume in the United States, but most robotic curricula are focused on basic psychomotor skills. There are limited curricula focused on advanced robotic technical and related non-technical skills. We describe a novel pilot curriculum for robotic hiatal hernia repair developed for senior surgical residents to provide training and standardized assessment of higher-order robotic technical and leadership skills. METHODS: Twelve senior residents, post-graduate year (PGY) 4 & 5, participated in a robotic hiatal hernia repair skills curriculum. Residents completed a pre- and post-survey on confidence and ability ratings on a 5-point Likert-type Scale, and a knowledge assessment. An informal faculty-led didactic was provided prior to the simulation. Residents were scored on two validated assessment tools: Ottawa Surgical Competency Operating Room Evaluation (O-SCORE) and Global Ratings Scale of Operative Performance (GRS) by faculty proctors. RESULTS: Confidence in ability to independently complete a robotic hiatal hernia case increased from mean of 2.6 ± 0.8 to 3.3 ± 0.6 (p = 0.0007). Following the simulation, residents reported increased overall confidence and ability to operate independently with mean scores of 3.3 ± 0.8 and 3.8 ± 0.9, respectively. Mean O-SCORE and GRS scores were 3.6 (range 2 - 4) and 25.4 (range 12 - 31), respectively. Number of prior live robotic cases was strongly positively correlated to O-SCORE (R = 0.84, p = 0.0006) and GRS (R = 0.88, p = 0.0002). CONCLUSION: Our pilot study suggests live-operative robotic training is not sufficient alone for advanced robotic skill training. Simulations such as this can be used to (1) practice advanced robotic technical and relevant non-technical skills such as communication and operating room leadership in a low stake setting and (2) assess residents in a standardized environment to eventually evaluate robotic competency.

Impact of COVID-19 on common non-elective general surgery diagnoses.

BACKGROUND: During the COVID-19 pandemic, public health and hospital policies were enacted to decrease virus transmission and increase hospital capacity. Our aim was to understand the association between COVID-19 positivity rates and patient presentation with EGS diagnoses during the COVID pandemic compared to historical controls. METHODS: In this cohort study, we identified patients ≥ 18 years who presented to an urgent care, freestanding ED, or acute care hospital in a regional health system with selected EGS diagnoses during the pandemic (March 17, 2020 to February 17, 2021) and compared them to a pre-pandemic cohort (March 17, 2019 to February 17, 2020). Outcomes of interest were number of EGS-related visits per month, length of stay (LOS), 30-day mortality and 30-day readmission. RESULTS: There were 7908 patients in the pre-pandemic and 6771 in the pandemic cohort. The most common diagnoses in both were diverticulitis (29.6%), small bowel obstruction (28.8%), and appendicitis (20.8%). The lowest relative volume of EGS patients was seen in the first two months of the pandemic period (29% and 40% decrease). A higher percentage of patients were managed at a freestanding ED (9.6% vs. 8.1%) and patients who were admitted were more likely to be managed at a smaller hospital during the pandemic. Rates of surgical intervention were not different. There was no difference in use of ICU, ventilator requirement, or LOS. Higher 30-day readmission and lower 30-day mortality were seen in the pandemic cohort. CONCLUSIONS: In the setting of the COVID pandemic, there was a decrease in visits with EGS diagnoses. The increase in visits managed at freestanding ED may reflect resources dedicated to supporting outpatient non-operative management and lack of bed availability during COVID surges. There was no evidence of a rebound in EGS case volume or substantial increase in severity of disease after a surge declined.

Robotic median arcuate ligament release: management algorithm and clinical outcomes from a large minimally invasive series.

BACKGROUND: Median arcuate ligament syndrome (MALS) is a rare and debilitating condition that remains difficult to diagnose. Proper patient selection remains key to achieving favorable outcomes for those undergoing MALR. The robotic technique facilitates a minimally invasive MALR approach given the fine precision of the instrumentation and stability of visualization. Here we describe our management algorithm and clinical outcomes for a large series of robotic MALR patients. METHODS: This retrospective cohort study analyzed adult patients who underwent robotic MALR performed by a single surgeon at a tertiary academic hospital from 2014 to 2021. The diagnosis of MALS was made using objective criteria from celiac artery duplex ultrasound with a peak systolic velocity of > 350 cm/s combined with a right upper quadrant abdominal ultrasound, esophagogastroduodenoscopy, and computer tomography or magnetic resonance angiography to exclude other diagnoses. Information on patient demographics, perioperative factors, and patient reported symptoms up to 1-year post-operatively were collected. RESULTS: A total of 74 patients underwent robotic MALR during the study period. The mean age was 27.3 ± 7.9 years and the majority of patients were female (n = 60/74, 81.1%). The most common presenting symptom was post-prandial abdominal pain (n = 65/74, 87.7%). The mean operative time was 52.6 ± 18.1 min. There were no conversions to open surgery and minimal blood loss (mean = 13.9 ± 8.4 mL). At 3-months, 12% (n = 9/74) of patients had persistent abdominal pain and underwent additional imaging. 5 of these 9 patients had persistently elevated DUS expiratory PSV and were referred for angioplasty. 3 of these 5 referred patients had resolution of abdominal pain after angioplasty. At 1-year follow up, 90.3% (n = 56/62) continued to have no abdominal pain. CONCLUSIONS: Through this series, the largest set of minimally invasive (laparoscopic or robotic) MALR procedures published to date, we show that with strict adherence to a management algorithm, the robotic approach to MALR is safe and feasible, with good patient outcomes.

Technique and Outcomes in Laparoscopic Repair of Morgagni Hernia in Adults.

Background: Morgagni hernias (MHs) are rare anteromedial congenital diaphragmatic hernias. This study describes the effectiveness of a laparoscopic approach for these defects. Methods: A prospectively collected institutional database at a tertiary referral center was queried for patients (≥18 years) with MHs. Results: Fifteen adults underwent laparoscopic MH repair. Abdominal pain was the most common presentation (71.5%), and 2 patients (13.3%) presented with acute obstruction. Laparoscopic bridged mesh repair was the most common approach (66.7%) and was achieved by suturing a bridged synthetic mesh to the diaphragmatic portion of the defect and fixing it with transfascial sutures and/or tacks to the anterior abdominal wall. Primary suture repair was utilized for smaller defects. No mortalities or recurrences occurred after 20.2 months median follow-up. Conclusions: Laparoscopic synthetic mesh repair of adult MHs offers an effective hernia repair with minimal complications and no detected recurrences in long-term follow-up of this patient sample.

Non-elective paraesophageal hernia repair: surgical approaches and short-term outcomes.

BACKGROUND: The majority of laparoscopic paraesophageal hernia (PEH) repairs are performed electively. We aimed to investigate the frequency of non-elective laparoscopic (MIS) PEH repair and compare 30-day outcomes to elective MIS repairs and non-elective open repairs. We hypothesized that an increasing percentage of non-elective PEH repairs would be performed laparoscopically and that this population would have improved outcomes compared to non-elective open PEH counterparts. METHODS: The 2011-2016 NSQIP PUFs were used to identify patients who underwent PEH repair. Case status was classified as open vs. MIS and elective versus non-elective. Preoperative patient characteristics, operative details, discharge destination, and 30-day postoperative complication rates were compared. Logistic regression was used to examine the impact of case status on 30-day mortality. RESULTS: We identified 20,010 patients who underwent PEH. There were an increasing number of MIS PEH repairs in NSQIP between 2011 and 2016. Non-elective repairs were performed in 2,173 patients and 73.4% of these were completed laparoscopically. Elective MIS patients were younger, had a higher BMI, and were more likely to be functionally independent (p < 0.01) than their non-elective counterparts. Non-elective MIS patients had a higher wound class and ASA class compared to their elective counterparts. Compared to elective MIS cases, non-elective MIS PEH repair was associated with increased odds of mortality, even after controlling for patient characteristics (OR = 1.76, p = 0.02). There was no statistically significant difference in mortality for non-elective MIS vs. non-elective open PEH repair. There is an increase in non-elective PEH repairs recorded in NSQIP over time studied. CONCLUSIONS: The population undergoing non-elective MIS PEH repairs is different from their elective MIS counterparts and experience a higher postoperative mortality rate. While the observed increased utilization of MIS techniques in non-elective PEH repairs likely provides benefits for the patient, there remain differences in outcomes for these patients compared to elective PEH repairs.

Surgery Resident Time Consumed by the Electronic Health Record.

OBJECTIVE: Time spent on the Electronic Health Record (EHR) influences surgical residents' clinical availability. Objective data assessing EHR usage among surgical residents are lacking and necessary. DESIGN/PARTICIPANTS: Active EHR usage data for 70 surgical residents were collected from April 2015 through April 2016. Active EHR usage was defined as more than 15 keystrokes, or 3 mouse clicks, or 1700 "mouse miles" per minute. Usage data of different specialties, interns (PGY 1), juniors (PGY 2, 3), and seniors (PGY 4, 5) were compared. SETTING: Carolinas Medical Center, Charlotte, NC. RESULTS: Interns spent more time than juniors on total EHR activities per day (134.5 vs 105.5 minutes, p < 0.001) and juniors spent more time per day than seniors (105.5 vs 78.7 minutes, p < 0.001). Among different EHR activities per patient, interns spent greater time than juniors on chart review (8.1 vs 6.2 minutes, p < 0.001), documentation (9.0 vs 6.5 minutes, p < 0.001), and orders (3.6 vs 3.0 minutes, p < 0.001). Juniors spent the same time as seniors on chart review (6.2 vs 6.5 minutes, p = 0.2). Juniors spent more time than seniors on documentation (6.5 vs 5.2 minutes, p < 0.001) and orders (3.0 vs 2.7 minutes, p < 0.05). Comparing EHR activities per patient among different specialties, General Surgery residents spent more time than Orthopedic residents on total EHR time (19.9 vs 15.9 minutes, p < 0.001), chart review (6.8 vs 5.7 minutes, p < 0.001), documentation (6.3 vs 5.6 minutes, p < 0.001), and orders (3.6 vs 2.6 minutes, p < 0.001). General Surgery residents spent less time than OB/GYN residents on total EHR time (19.9 vs 22 minutes, p < 0.01), chart review (6.8 vs. 7.5 minutes, p < 0.05), and documentation (6.3 vs 7.6 minutes, p < 0.001), but more time on orders (3.6 vs 2.9 minutes, p < 0.001). CONCLUSIONS: These are the first reported objective findings on surgical resident use of the EHR and may provide an opportunity for improvement in EHR training and usage.
