Objective: To assess impact of participation in a positive psychology coaching program on trainee burnout and well-being.

Background: Coaching using principles of positive psychology can improve well-being and reduce physician burnout. We hypothesized that participation in a coaching program would improve pediatric surgery trainee well-being.

Methods: With IRB approval, a coaching program was implemented during the COVID-19 pandemic (September 2020 to July 2021) in the American Pediatric Surgical Association. Volunteer pediatric surgery trainees (n=43) were randomized to receive either one-on-one quarterly virtual coaching (n=22) from a pediatric surgeon trained in coaching skills or wellness reading materials (n=21). Participants completed prestudy and poststudy surveys containing validated measures, including positive emotion, engagement, relationships, meaning, accomplishment, professional fulfillment, burnout, self-valuation, gratitude, coping skills, and workplace experiences. Results were analyzed using the Wilcoxon rank sum test, Kruskal-Wallis test, or χ 2 test.

Results: Forty trainees (93%) completed both the baseline and year-end surveys and were included in the analysis. Twenty-five (64%) were female, mean age 35.7 (SD 2.3), and 65% were first-year fellows. Coached trainees showed an improved change in positive emotion, engagement, relationships, meaning, accomplishment ( P =0.034), burnout ( P =0.024), and gratitude ( P =0.03) scores from precoaching to postcoaching compared with noncoached trainees. Coping skills also improved. More coaching sessions were associated with higher self-valuation scores ( P =0.042), and more opportunities to reflect were associated with improved burnout and self-valuation.

Conclusions: Despite the stress and challenges of medicine during COVID-19, a virtual positive psychology coaching program provided benefits in well-being and burnout to pediatric surgery trainees. Coaching should be integrated into existing wellness programs to support the acquisition of coping skills that help trainees cope with the stressors they will face during their careers.

Objective: This study aims to assess the costs of a same-day discharge (SDD) enhanced recovery pathway for diverting loop ileostomy (DLI) closure compared with a standard institutional enhanced recovery protocol.

Background: Every year, 50,155 patients in the United States undergo temporary stoma reversal. While ambulatory stoma closure has shown promise, widespread adoption remains slow. This study builds on previous research, focusing on the costs of a novel SDD protocol introduced in 2020.

Methods: A retrospective case-control study was conducted at Mayo Clinic, Rochester, Minnesota, and Mayo Clinic, Jacksonville, Florida, comparing patients undergoing SDD DLI closure from August 2020 to February 2023 to those in a matched cohort receiving standard inpatient enhanced recovery protocol. Patients were matched based on age, sex, american society of anesthesiologists score, surgery period, and hospital. Primary outcomes included direct hospitalization and additional costs in the 30 days postdischarge.

Results: The SDD group (n = 118) demonstrated a significant reduction in median index episode hospitalization and 30-day postoperative costs compared with the inpatient group (n = 236), with savings of $4827 per patient. Complication rates were similar, and so were readmission and reoperation rates.

Conclusions: Implementation of the SDD for DLI closure is associated with substantial cost savings without compromising patient outcomes. The study advocates for a shift towards SDD protocols, offering economic benefits and potential improvements in health care resource utilization.

Objective: The aim of this study was to evaluate the different phases of the learning curve for robotic distal pancreatectomy (RDP) in international expert centers.

Summary background data: RDP is an emerging minimally invasive approach; however, only limited, mostly single center data are available on its safe implementation, including the learning curve.

Methods: Consecutive patients undergoing elective RDP from 16 expert centers across three continents were included to assess the learning curve. Based on the first 100 RDPs at each center, three cutoffs were used to define the learning curve: operative time for competency, major complications (Clavien-Dindo grade ≥III) for proficiency, and textbook outcome for mastery. Clinical outcomes before and after the cutoffs were compared.

Results: The learning curve analysis was conducted on 1109 of 2403 RDPs. Competency, proficiency, and mastery, respectively, were reached after 46, 63, and 73 RDP procedures. After competency, operative time decreased from 245 to 235 minutes (P=0.002). Attaining proficiency was reflected by a reduction in the rate of major complications from 20% to 15% (P=0.012), and mastery was associated with a higher proportion of patients with textbook outcome (71% vs. 63%; P=0.028). The postoperative pancreatic fistula rate remained stable along the learning curve, ranging between 18.5% and 21.5%. Previous laparoscopic experience accelerated the learning process by virtue of reduced operative time and an earlier decrease in major complications.

Conclusion: Competency, proficiency, and mastery for RDP were reached after 46, 63, and 73 procedures, respectively, at international expert centers. The findings highlight that the learning curves for intraoperative parameters are completed earlier; however, extensive experience is needed to master RDP.

Metabolic surgery - operating on a normal organ for a beneficial metabolic gain - is not only an emerging discipline of surgery but the progenitor of therapy for the major global afflictions of atherosclerotic cardiovascular disease, cancer, type 2 diabetes, and obesity, as well as at least 18 other disease entities.

Background: Postoperative morbidity can reduce quality of life, physical performance, and tolerability of postoperative chemotherapy in patients with colorectal liver metastases (CRLM). Exercise can improve these outcomes in some cancer populations. However, it remains unknown whether exercise can be delivered in the early postoperative period following surgery for CRLM without increasing the risk of harms.

Objective: The primary objective was to compare the number of serious adverse events (SAEs) with exercise intervention versus control. The secondary objectives were to compare non-SAEs, chemotherapy dose modifications, patient-reported outcomes, cardiorespiratory fitness, and physical performance.

Methods: Patients with CRLM scheduled to open surgery with or without postoperative chemotherapy were randomized 2:1 to intervention or control. The intervention group performed 30-50 min low-to-high intensity exercise 5 times/week for 8 weeks, initiated one day after postoperative hospital discharge. The primary outcome was SAEs. The secondary outcomes were SAEs; chemotherapy dose modifications; patient-reported outcomes; cardiorespiratory fitness; and physical performance.

Results: Fifty-five participants were randomized. The number of SAEs was similar between the groups (between-group difference [95% CI]: -0.07 [-0.59; 0.43] events), whereas the number of non-SAEs was lower in intervention (between-group difference [95% CI]: -4.65 [-9.14; -0.17] events). We found between-group differences in time to postoperative chemotherapy (intervention: 25 days, control; 42 days) and chemotherapy dose modifications (RR [95%CI]: 0.55 [0.35; 0.88]). Additionally, we found between-group differences in quality of life, cardiorespiratory fitness, and physical performance, in favor of intervention.

Conclusions: Early-onset postoperative exercise exhibit a favorable harms-benefit profile in patients with CRLM. This warrants further investigation in larger randomized controlled trials.

Trial registration: Prospectively registered at clinicaltrials.gov (NCT04751773).

Objective: To determine the association between residence in racialized neighborhoods with direct healthcare expenditure and days at home (DAH) after moderate to severe traumatic brain injury (TBI).

Summary background data: Differences in ethno-racial background have been associated with health outcome disparities. Much of this prior research was conducted in settings without universal healthcare coverage. The influence of ethno-racial background on health outcomes after TBI in universal healthcare settings remains unclear.

Methods: This retrospective multicenter cohort study utilized linked administrative health data to identify adults sustaining moderate to severe TBI between 2009-2021. The primary exposure was an area-level index corresponding to the degree of racialized and immigrant populations within neighborhoods of residence (Q1-least racialized; Q5-most racialized). Co-primary outcomes were direct healthcare expenditure and DAH365days after injury. Secondary outcomes included discharge to rehabilitation and functional independence measure (FIM) scores at rehabilitation discharge.

Results: 6,188 patients met inclusion criteria. Patients in the most racialized neighborhoods incurred higher crude and adjusted direct healthcare costs compared to those in the least racialized neighborhoods. This effect was driven predominantly by physician claims and acute care costs. There were no significant differences in crude or adjusted DAH across quintiles. Access to rehabilitation and discharge FIM scores were comparable for patients residing different racialized neighborhood quintiles.

Conclusions: Despite differences in healthcare expenditure, this study found similar home time, access to rehab and discharge FIM scores for TBI patients according to racialized neighborhood residence. Recognizing the limitations of area-level indices, our findings suggest equitable care delivery in a publicly funded universal care environment.

Importance: The current research aimed to conduct a detailed analysis of intraoperative surgical performance, short-term outcomes, identify and categorize technical errors, and hazard-zones enacted during total gastrectomy performed robotically and laparoscopically by surgeons. Prospective research is needed to determine whether the technical advantages of robotic surgery translate to patient outcomes.

Objective: Identify and process risk areas in robot-assisted total gastrectomy (RTG) and laparoscopic total gastrectomy (LTG) to get the best patient results.

Design: Patients undergoing RTG and LTG were recruited and randomized into the study. Six consultant/attending surgeons participated in this study and all surgical procedures were recorded. The unedited surgical video-recordings were handed over to third-party experts for granular analysis of the procedures using objective clinical human reliability analysis (OC-HRA) for the quality of intraoperative performance, technical errors, intraoperative complications.

Setting: This study is a single center prospective randomized controlled trial.

Participants: 82 patients were recruited and participated in this study with 40 cases undergoing RTG and 42 cases for LTG.

Interventions: RTG vs LTG.

Main outcomes and measures: Determine whether RTG or LTG can provide the better intraoperative technical performance and identify the most hazardous zone (area) during total gastrectomy (TG).

Results: The technical errors enacted and identified in the RTG and the LTG were (46.11±5.63 VS 58.79±8.45, P＜0.001) respectively. The highest number of technical errors was identified during the dissection of the supra-pancreatic lymph nodes (Task Zones3, TZ3), including No.5, 7, 8a, 9, 11p, and 12a to complete the nodal clearance around the celiac artery and its trifurcation (7.29±1.88 VS 9.43±2.24, P <0.001) in both RTG and LTG. The number of lymph nodes harvested with RTG was higher than LTG (35.36±7.51 VS 30.54±6.95, P=0.016), especially in the upper margin of the pancreas (13.32±4.17 VS 9.36±3.81, P＜0.001). The total cost of hospitalization in the RTG group cost 3% more than LTG group ($15953.41±3533.91 VS $12198.26±2761.27, P＜0.001).

Conclusions: This study offers compelling OC-HRA evidence demonstrating that RTG facilitates significantly superior technical performance compared to LTG. Whether examining short-term clinical outcomes or intraoperative operations, the robotic surgery system consistently outperforms laparoscopic surgery. Lymph node dissection in the supra-pancreatic region emerged as a major hazard zone in both procedures.

Objective: To investigate patency and clinical outcomes of alloplastic and other venous interposition graft materials in pancreatic surgery.

Background: Vascular pancreatic surgery is increasingly performed for locally advanced pancreatic neoplasms. Different than other centers, we prefer to use alloplastic vascular graft materials for superior mesenteric vein and portal vein interposition in pancreatic surgery. Advantages are off-the-shelf availability at any customizable length, different diameters, and ring-enforcement but proposed concerns are their thrombogenicity and fatal complications.

Methods: Patients who underwent elective pancreatic resections with mesoportal venous interposition grafts (ISGPS type 4) between 2003-2022 were identified from the institutional pancreatectomy registry. Alloplastic vascular grafts imply synthetic materials, either based on polytetrafluorethylene (PTFE) or polyethylene terephthalate (PET). Surgical details, clinicopathological, and follow-up data were analyzed. The patients were followed for graft patency by cross-sectional imaging.

Results: In this study, 201 patients with venous interposition grafts were included (23% simultaneous arterial resections). Total pancreatectomy (41%) and pancreatoduodenectomy (35%) were the most frequent procedures. Vascular graft materials were alloplastic in 180 patients (83% PTFE and 17% PET) with a median diameter of 10 mm and a median length of 33 mm (measurement by CT scan). Patency rates among all graft materials at 7-, 30-, and 90-days were 99%, 93%, and 87%. Alloplastic grafts demonstrated superior patency over other materials (hazard ratio 2.7, P=0.009), and PTFE reached a 1-year patency of 78%. The all-cause 90-day mortality rate was 10%. No graft infection occurred.

Conclusion: Alloplastic venous vascular grafts are safe and readily available tools in pancreatic surgery, especially for long-segmental mesoportal venous reconstructions.
