RESUMO
INTRODUCTION: There is a paucity of literature comparing safety outcomes between formal fundoplication and gastric fixation procedures for hiatal hernia repairs, especially in the emergency setting. The objective of this study was to evaluate 30-day clinical outcomes between fundoplication and gastric fixation performed in emergency hiatal hernia repairs. METHODS: A retrospective cohort study using the National Surgery Quality Improvement Program (NSQIP) database from 2011 to 2021 was conducted. The study population was determined using ICD9/10 codes describing diaphragmatic hernia without obstruction or gangrene, with obstruction, and with gangrene. Elective cases were excluded. CPT codes were used to group fundoplication procedures and gastric fixation procedures. The primary outcome was the 30-day complication rate. Secondary outcomes included 30-day readmission, reoperation and mortality rates. A multivariable logistic regression analysis was used to adjust for clinically relevant confounding variables. RESULTS: A total of 971 and 346 were in the fundoplication and gastric fixation groups, respectively. Fundoplication was associated with a significantly lower (p < 0.05) 30-day complication, reoperation and mortality rates. There was no statistically significant difference with respect to readmission. After adjustment, fundoplication was significantly associated with a decrease in odds of 30-day complications (OR 0.53, p < 0.001 95% CI 0.40-0.71) and mortality (OR 0.55, p = 0.033 95% CI 0.32-0.95). However, there was no significant difference with respect to 30-day readmission (OR 0.86, p = 0.449 95% CI 0.59-1.27) and reoperation (OR 0.66, p = 0.063 95% CI 0.42-1.02). CONCLUSION: Patients with hiatal hernias that underwent emergent repair with fundoplication had a significantly lower 30-day complication and mortality rates compared to those who underwent gastric fixation procedures. Fundoplication is a safe and feasible approach to manage hiatal hernias in the emergency setting for select patients.
RESUMO
BACKGROUND: Robot-assisted surgery has been rapidly adopted. It is important to define the learning curve to inform credentialling requirements, training programs, identify fast and slow learners, and protect patients. This study aimed to characterize the hospital learning curve for common robot-assisted procedures. STUDY DESIGN: This cohort study, using administrative health data for Ontario, Canada, included adult patients who underwent a robot-assisted radical prostatectomy (RARP), total robotic hysterectomy (TRH), robot-assisted partial nephrectomy (RAPN), or robotic portal lobectomy using four arms (RPL-4) between 2010 and 2021. The association between cumulative hospital volume of a robot-assisted procedure and major complications was evaluated using multivariable logistic models adjusted for patient characteristics and clustering at the hospital level. RESULTS: A total of 6814 patients were included, with 5230, 543, 465, and 576 patients in the RARP, TRH, RAPN, and RPL-4 cohorts, respectively. There was no association between cumulative hospital volume and major complications. Visual inspection of learning curves demonstrated a transient worsening of outcomes followed by subsequent improvements with experience. Operative time decreased for all procedures with increasing volume and reached plateaus after approximately 300 RARPs, 75 TRHs, and 150 RPL-4s. The odds of a prolonged length of stay decreased with increasing volume for patients undergoing a RARP (OR 0.87; 95% CI 0.82-0.92) or RPL-4 (OR 0.77; 95% CI 0.68-0.87). CONCLUSION: Hospitals may adopt robot-assisted surgery without significantly increasing the risk of major complications for patients early in the learning curve and with an expectation of increasing efficiency.

BACKGROUND: Digital surgery is a new paradigm within the surgical innovation space that is rapidly advancing and encompasses multiple areas. METHODS: This white paper from the SAGES Digital Surgery Working Group outlines the scope of digital surgery, defines key terms, and analyzes the challenges and opportunities surrounding this disruptive technology. RESULTS: In its simplest form, digital surgery inserts a computer interface between surgeon and patient. We divide the digital surgery space into the following elements: advanced visualization, enhanced instrumentation, data capture, data analytics with artificial intelligence/machine learning, connectivity via telepresence, and robotic surgical platforms. We will define each area, describe specific terminology, review current advances as well as discuss limitations and opportunities for future growth. CONCLUSION: Digital Surgery will continue to evolve and has great potential to bring value to all levels of the healthcare system. The surgical community has an essential role in understanding, developing, and guiding this emerging field.

BACKGROUND: Associations between procedure volumes and outcomes can inform minimum volume standards and the regionalization of health services. Robot-assisted surgery continues to expand globally; however, data are limited regarding which hospitals should be using the technology. STUDY DESIGN: Using administrative health data for all residents of Ontario, Canada, this retrospective cohort study included adult patients who underwent a robot-assisted radical prostatectomy (RARP), total robotic hysterectomy (TRH), robot-assisted partial nephrectomy (RAPN), or robotic portal lobectomy using 4 arms (RPL-4) between January 2010 and September 2021. Associations between yearly hospital volumes and 90-day major complications were evaluated using multivariable logistic regression models adjusted for patient characteristics and clustering at the level of the hospital. RESULTS: A total of 10,879 patients were included, with 7567, 1776, 724, and 812 undergoing a RARP, TRH, RAPN, and RPL-4, respectively. Yearly hospital volume was not associated with 90-day complications for any procedure. Doubling of yearly volume was associated with a 17-min decrease in operative time for RARP (95% confidence interval [CI] - 23 to - 10), 8-min decrease for RAPN (95% CI - 14 to - 2), 24-min decrease for RPL-4 (95% CI - 29 to - 19), and no significant change for TRH (- 7 min; 95% CI - 17 to 3). CONCLUSION: The risk of 90-day major complications does not appear to be higher in low volume hospitals; however, they may not be as efficient with operating room utilization. Careful case selection may have contributed to the lack of an observed association between volumes and complications.
