RESUMEN
BACKGROUND: In breast oncologic surgery, 75% of patients receive a postoperative opioid prescription at discharge, and 10%-20% will develop persistent opioid use. To inform future institutional guidelines, the objective of this study was to determine baseline opioid prescribing patterns in a single high-volume, referral-based breast center. We hypothesized that opioid prescribing practices varied between procedures and operating surgeons. METHODS: A retrospective analysis of all women undergoing breast cancer surgery between January and December 2019. Opioid prescriptions at discharge were converted to morphine milligram equivalents (MME). The primary outcome of interest was MME prescribed at discharge. Multiple linear regression was used to identify factors independently associated with MME prescribed. RESULTS: 392 patients met inclusion criteria; 68.3% underwent partial mastectomy. Median age was 61 (interquartile range [IQR] 51-70). Median MME prescribed at discharge was 112.5 (IQR 75-150); 83.9% of patients were prescribed co-analgesia. The prescriber was a trainee in 37.7% of cases. 15 patients (3.8%) required opioid renewal. On multivariate analysis, axillary procedure was associated with increased MME (ß = 17, 95% CI 5.5-28 and ß = 32, 95% CI 17-47, for sentinel node and axillary dissection, respectively). However, the factor with the greatest impact on MME was operating surgeon (ß = 72, 95% CI 58-87). Residents prescribed less MME compared to attending surgeons (ß = 11, 95% CI -22; -0.06). CONCLUSION: In a tertiary care center, the operating surgeon had the greatest influence on opioid prescribing practices, and trainees tended to prescribe less MME. These findings support the need for a standardized approach to optimize prescribing and reduce opioid-related harms after oncologic breast surgery.

BACKGROUND: Emerging technologies are being incorporated in surgical education. The use of such technology should be supported by evidence that the technology neither distracts nor overloads the learner and is easy to use. To teach chest tube insertion, we developed an e-learning module, as part of a blended learning program delivered prior to in-person hands-on simulation. This pilot study was aimed to assess learning effectiveness of this blended learning, and cognitive load and the usability of e-learning. METHODS: The interactive e-learning module with multimedia content was created following learning design principles. In advance of the standard simulation, 13 first-year surgical residents were randomized into two groups: 7 received the e-learning module and online reading materials (e-learning group); 6 received only the online reading materials (controls). Knowledge was evaluated by pre-and post-tests; technical performance was assessed using a Global Rating Scale by blinded assessors. Cognitive load and usability were evaluated using rating scales. RESULTS: The e-learning group showed significant improvement from baseline in knowledge (P = .047), while controls did not (P = .500). For technical skill, 100% of residents in the e-learning group reached a predetermined proficiency level vs 60% of controls (P = .06). The addition of e-learning was associated with lower extrinsic and greater germane cognitive load (P = .04, .03, respectively). Usability was evaluated highly by all participants in e-learning group. CONCLUSION: Interactive e-learning added to hands-on simulation led to improved learning and desired cognitive load and usability. This approach should be evaluated in teaching of other procedural skills.

PURPOSE: This study aimed to understand patients' experiences undergoing cancer surgery during the COVID-19 pandemic. In response to COVID-19, many elective cancer surgeries were delayed creating a massive backlog of cases. Patients' experiences with surgical delays may inform healthcare systems' responses to the backlog of cases and guide preparations for future healthcare emergencies. METHODS: This was a qualitative description study. Patients undergoing general surgery for cancer at two university-affiliated hospitals between March 2020 and January 2021 were invited to one-to-one interviews. Patients were purposefully selected using quota sampling until interviews produced no new information (i.e., thematic saturation). Interviews were conducted using a semi-structured guide and analyzed according to inductive thematic analysis. RESULTS: Twenty patients were included [mean age 64 ± 12.9; male (n = 10); surgical delay (n = 14); cancer sites: breast (n = 8), skin (n = 4), hepato-pancreato-biliary (n = 4), colorectal (n = 2), and gastro-esophageal (n = 2)]. When determining their willingness to undergo surgery, patients weighed the risk of COVID-19 infection against the urgency of their disease. Changes to the hospital environment (e.g., COVID-19 preventative measures) and deviations from expected treatment (e.g., alternative treatments, remote consultations, rescheduled care) caused diverse psychological responses, ranging from increased satisfaction to severe distress. Patients employed several coping strategies to mitigate distress, including eliciting reassurance from care providers, seeking information from unconventional sources, and reframing care interruptions. CONCLUSIONS: Changes in care during the pandemic elicited diverse psychological responses from patients undergoing cancer surgery. Coping was facilitated by consistent communication with providers, emphasizing the importance of patient-centered expectation setting as we prepare for the future within and beyond the pandemic.

INTRODUCTION: Self-review of recorded surgical procedures offers new opportunities for trainees to extend technical learning outside the operating-room. Valid tools for self-assessment are required prior to evaluating the effectiveness of video-review in enhancing technical learning. Therefore, we aimed to contribute evidence regarding the validity of intraoperative performance assessment tools for video-based self-assessment by general surgery trainees when performing laparoscopic cholecystectomies. METHODS AND PROCEDURES: Using a web-based platform, general surgery trainees in a university-based residency program submitted recorded laparoscopic cholecystectomy procedures where they acted as the supervised primary surgeon. Attending surgeons measured operative performance at the time of surgery using general and procedure-specific assessment tools [Global Operative Assessment of Laparoscopic Skills (GOALS) and Operative Performance Rating System (OPRS), respectively] and entrustability level (O-SCORE). Trainees self-evaluated their performance from video-review using the same instruments. The validity of GOALS and OPRS for trainee self-assessment was investigated by testing the hypotheses that self-assessment scores correlate with (H1) expert assessment scores, (H2) O-SCORE, and (H3) procedure time and that (H4) self-assessment based on these instruments differentiates junior [postgraduate year (PGY) 1-3] and senior trainees (PGY 4-5), as well as (H5)simple [Visual Analogue Scale (VAS) ≤ 4] versus complex cases (VAS > 4). All hypotheses were based on previous literature, defined a priori, and were tested according to the COSMIN consensus on measurement properties. RESULTS: A total of 35 videos were submitted (45% female and 45% senior trainees) and self-assessed. Our data supported 2 out of 5 hypotheses (H1 and H4) for GOALS and 3 out of 5 hypotheses (H1, H4 and H5) for OPRS, for trainee self-assessment. CONCLUSIONS: OPRS, a procedure-specific assessment tool, was better able to differentiate between groups expected to have different levels of intraoperative performance, compared to GOALS, a general assessment tool. Given the interest in video-based learning, there is a need to further develop valid procedure-specific tools to support video-based self-assessment by trainees in a range of procedures.

BACKGROUND: Pain management after bariatric surgery remains challenging given the risk for analgesia-related adverse events (e.g., opioid use disorder, marginal ulcers). Identifying modifiable factors associated with patient-reported pain outcomes may improve quality of care. We evaluated the extent to which patient and procedural factors predict 7-day post-discharge pain intensity, pain interference, and satisfaction with pain management after bariatric surgery. METHODS: This prospective cohort study included adults undergoing laparoscopic bariatric surgery at two university-affiliated hospitals and one private clinic. Preoperative assessments included demographics, Pain Catastrophizing Scale (score range 0-52), Patient Activation Measure (low [< 55.1] vs. high [≥ 55.1]), pain expectation (0-10), and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) anxiety and depression scales. At 7 days post-discharge, assessments included PROMIS-29 pain intensity (0-10) and pain interference scales (41.6-75.6), and satisfaction with pain management (high [10-9] vs. lower [8-0]). Linear and logistic regression were used to assess the association of pain outcomes with potential predictors. RESULTS: Three hundred and fifty-one patients were included (mean age = 44 ± 11 years, BMI = 45 ± 8 kg/m2, 77% female, 71% sleeve gastrectomy). At 7 days post-discharge, median (IQR) patient-reported pain intensity was 2.5 (1-5), pain interference was 55.6 (52.0-61.2), and 76% of patients reported high satisfaction with pain management. Pain intensity was predicted by preoperative anxiety (ß + 0.04 [95% CI + 0.01 to + 0.07]) and pain expectation (+ 0.15 [+ 0.05 to + 0.25]). Pain interference was predicted by preoperative anxiety (+ 0.22 [+ 0.11 to + 0.33]), pain expectation (+ 0.47 [+ 0.10 to + 0.84]), and age (- 0.09 [- 0.174 to - 0.003]). Lower satisfaction was predicted by low patient activation (OR 1.94 [1.05-3.58]), higher pain catastrophizing (1.03 [1.003-1.05]), 30-day complications (3.27 [1.14-9.38]), and age (0.97 [0.948-0.998]). CONCLUSION: Patient-related factors are important predictors of post-discharge pain outcomes after bariatric surgery. Our findings highlight the value of addressing educational, psychological, and coping strategies to improve postoperative pain outcomes.

INTRODUCTION: In the current opioid crisis, bariatric surgical patients are at increased risk of harms related to postoperative opioid overprescribing. This study aimed to assess the extent to which opioids prescribed at discharge after bariatric surgery are consumed by patients. METHODS: This multicenter prospective cohort study included adult patients (≥ 18yo) undergoing laparoscopic bariatric surgery. Preoperative assessments included demographics and patient-reported measures. Information regarding surgical and perioperative care interventions (including discharge prescriptions) was obtained from medical records. Self-reported opioid consumption was assessed weekly up to 30 days post-discharge. Number of opioid pills prescribed and consumed was compared using Wilcoxon signed-rank test. Zero-inflated negative binomial regression was used to identify predictors of post-discharge opioid consumption. RESULTS: We analyzed 351 patients (mean age 44 ± 11 years, BMI 45 ± 8.0 kg/m2, 77% female, 71% sleeve gastrectomy, length of stay 1.6 ± 0.6 days). The quantity of opioids prescribed at discharge (median 15 pills [IQR 15-16], 112.5 morphine milligram equivalents (MMEs) [IQR 80-112.5]) was significantly higher than patient-reported consumption (median 1 pill [IQR 0-5], 7.5 MMEs [IQR 0-37.5]) (p < 0.001). Overall, 37% of patients did not take any opioids post-discharge and 78.5% of the opioid pills prescribed were unused. Increased post-discharge opioid consumption was associated with male sex (IRR 1.54 [95%CI 1.14 to 2.07]), higher BMI (1.03 [95%CI 1.01 to 1.05]), preoperative opioid use (1.48 [95%CI 1.04 to 2.10]), current smoking (2.32 [95%CI 1.44 to 3.72]), higher PROMIS-29 depression score (1.03 [95% CI 1.01 to 1.04]), anastomotic procedures (1.33 [95%CI 1.01 to 1.75]), and number of pills prescribed (1.04 [95%CI 1.01 to 1.06]). CONCLUSION: This study supports that most opioid pills prescribed to bariatric surgery patients at discharge are not consumed. Patient and procedure-related factors may predict opioid consumption. Individualized post-discharge analgesia strategies with minimal or no opioids may be feasible and should be further investigated in future research.

BACKGROUND: Primary nonparasitic splenic cysts (NPSC) are typically diagnosed incidentally. The management of large (≥ 5 cm) asymptomatic cysts remains controversial; there is a lack of evidence guiding management. The purpose of this study was to describe the outcomes of nonoperative management of large NPSC. METHODS: Patients diagnosed with NPSC between January 2004 and December 2019 were identified at our academic institution. Adult patients with an NPSC of at least 5 cm who had at least 1 additional hospital visit were included. Data are presented as medians with interquartile ranges (IQR). RESULTS: We identified 512 medical records that included the term splenic cyst during the study period. Sixty-eight of the patients had no reported cyst size, 410 had cysts smaller than 5 cm, 1 patient underwent an elective splenectomy at another institution and 12 patients were excluded for other reasons; 21 patients with cysts of at least 5 cm were included in the study. Eight symptomatic patients underwent surgery at our institution. Of these, 2 presented acutely: 1 with hemoperitoneum who required admission for transfusions and later underwent elective laparoscopic splenectomy and 1 with increasingly severe abdominal pain who underwent laparoscopic cyst unroofing. The remaining 6 symptomatic patients had elective surgery for pain (4 cyst unroofing, 1 total splenectomy, 1 partial splenectomy). Thirteen patients were asymptomatic (10 female, median age 49.2 [IQR 38.1 to 64.6] yr). Two of these patients chose to undergo elective surgery. The remaining 11 asymptomatic patients, with a median initial cyst size of 8.0 (IQR 5.3 to 10.8) cm, were followed for a median of 31.0 (IQR 23.5 to 71.0) months. There was no change in median cyst size (0 [IQR -1 to 0] cm), and none of these patients underwent intervention for their NPSC. CONCLUSION: Asymptomatic patients managed nonoperatively for large NPSC did not become symptomatic or require intervention during the study period. This supports watchful waiting with serial radiologic and clinical monitoring for asymptomatic large NPSC.

INTRODUCTION: Emergency department (ED) visits after surgery represent a significant cost burden on the healthcare system. Furthermore, many ED visits are related to issues of healthcare delivery services and may be avoidable. Few studies have assessed the reasons for ED visits after colorectal surgery. The main objectives of this study were to: (1) identify the reasons why patients presented to the ED within 30 postoperative days and (2) determine if these visits were potentially preventable. METHODS: A retrospective chart review was conducted on elective major colorectal surgery cases performed in a single center between 01/2017 and 07/2019. Data collected included demographics, medical history, intraoperative details, postoperative complications, ED visits within 30 postoperative days, and readmissions. Each ED visit was assessed by two reviewers and graded on a scale adapted from the New York University ED algorithm. The gradings were: (1) non-emergent, (2) emergent but treatable in an ambulatory setting, (3) emergent/ED-care required but preventable if timely outpatient care was available, and (4) emergent/ED-care required and non-preventable. Grades 1-3 were deemed potentially preventable. Logistic regression identified independent predictors of potentially preventable visits. RESULTS: Six hundred and twenty five patients were included in the final analysis. 110 (17.6%) patients presented to the ED within 30 days. The most common cause of ED visit were ileus/small bowel obstruction (SBO) (16.4%), superficial wound infection (15.5%), genitourinary issues (10.9%), and non-infectious gastrointestinal issues (nausea, malnutrition, diarrhea, high output stomas) (10.9%). After review, 51.8% of visits were considered potentially preventable (Grade 1-3). The most common causes of preventable ED visits were superficial wound infection (24.6%), non-infectious gastrointestinal issues (19.3%), and minor bleeding (14.0%). Creation of a new stoma was the only independent risk factor for potentially preventable ED visits (OR 2.14, 95%CI 1.03-4.47). CONCLUSION: Approximately half of ED visits within 30 days of discharge were potentially preventable. These findings indicate a need to improve access to outpatient care to reduce preventable ED visits after elective colorectal surgery.

INTRODUCTION: Incisional hernia repair (IHR) carries a high risk of wound complications. Thirty-day outcomes are frequently used in comparative-effectiveness research, but may miss a substantial number of surgical site occurrences (SSO) including surgical site infection (SSI). The objective of this study was to determine an optimal length of follow-up to detect SSI after IHR. METHODS: All adult patients undergoing open IHR at a single academic center over a 3 year period were reviewed. SSIs, non-infectious SSOs, and wound-related readmissions were recorded up to 180 days. The primary outcome was the proportion of SSIs detected at end-points of 30, 60, and 90 days of follow-up. Time-to-event analysis was performed for all outcomes at 30, 60, 90, and 180 days. Logistic regression was used estimate the relative risk of SSI for relevant risk factors. RESULTS: A total of 234 patients underwent open IHR. Median follow-up time of 102 days. Overall incidence of SSI was 15.8% with median time to occurrence of 23 days. Incidence of non-infectious SSO was 33.2%, and SSO-related readmission was 12.8%. At 30, 60, and 90 days sensitivity was 81.6%, 89.5%, and 92.1 for SSI, and 46.7%, 76.7%, and 83.3% for readmission. In regression analysis, body mass index (RR 1.08, 95% CI 1.00, 1.15, p = 0.04) anterior component separation (RR 4.21, 95% CI 2.09, 6.34, p = 0.003), and emergency surgery (RR 3.25, 95% CI 1.47, 5.02, p = 0.01), were independently associated with SSI after adjusting for age, sex, contamination class, and procedure duration. CONCLUSION: A considerable proportion of SSIs occurred beyond 30 days, but 90-day follow-up detected 92% of SSIs. Follow-up to 90 days captured only 83% of SSO-related readmissions. These results have implications for the design of trials evaluating wound complication after open IHR, as early endpoints may miss clinically relevant outcomes and underestimate the number needed to treat. Where possible, we recommend a minimum follow-up of 90 days to estimate wound complications following open IHR.

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.

BACKGROUND: Recent literature reports a decrease in healthcare-seeking behaviours by adults during the Covid-19 pandemic. Given that emergency general surgery (GS) conditions are often associated with high morbidity and mortality if left untreated, the objective of this study was to describe and quantify the impact of the Covid-19 pandemic on rates of emergency department (ED) utilization and hospital admission due to GS conditions. METHODS: This cohort study involved the analysis of an institutional database and retrospective chart review. We identified adult patients presenting to the ED in a network of three teaching hospitals in Montreal, Canada during the first wave of the Covid-19 pandemic (March13-May13, 2020) and a control pre-pandemic period (March13-May13, 2019). Patients with GS conditions were included in the analysis. ED utilization rates, admission rates and 30-day outcomes were compared between the two periods using multivariate regression analysis. RESULTS: During the pandemic period, 258 patients presented to ED with a GS diagnosis compared to 351 patients pre-pandemically (adjusted rate ratio (aRR) 0.75; p < 0.001). Rate of hospital admission during the pandemic was also significantly lower (aRR = 0.77, p < 0.001). Patients had a significantly shorter ED stay during the pandemic (adjusted mean difference 5.0 h; p < 0.001). Rates of operative management during the pandemic were preserved compared to the pre-pandemic period. There were no differences in 30-day complications (adjusted odds ratio (aOR) 1.46; p = 0.07), ED revisits (aOR 1.10; p = 0.66) and (re)admissions (aOR 1.42; p = 0.22) between the two periods. CONCLUSION: There was a decrease in rates of ED utilization and hospital admissions due to GS conditions during the first wave of the Covid -19 pandemic; however, rates of operative management, complications and healthcare reutilization were unchanged. Although our findings are not generalizable to patients who did not seek healthcare, it was possible to successfully uphold institutional standards of care once patients presented to the ED.

BACKGROUND: Laparoscopic suturing (LS) is an essential technique required for a wide range of procedures, and it is one of the most challenging for surgical trainees to master. We designed and collected validity evidence for advanced LS tasks using an automated suturing device and evaluated the perceived educational value of the tasks. METHODS: This project was a multicentre prospective study involving McGill University, University of Toronto (UofT), and Louisiana State University (LSU) Health New Orleans. Novice (NS) and experienced (ES) surgeons performed suturing under tension (UT) and continuous suturing (CS) tasks. ES performed the tasks twice to establish proficiency benchmarks, and they were interviewed to develop formative feedback tools (FFT). Participants were assessed on completion time, error, Global Operative Assessment of Laparoscopic Skills (GOALS), and FFT. Data were analyzed using descriptive and inferential statistical methods. RESULTS: Twenty-seven participants (13 ES, 14 NS, median age 34 years; 85% male) completed the study. Eight were attending surgeons, 7 fellows, 4 PGY5, 5 PGY4, and 3 PGY3 (18 from McGill, 5 UofT, and 4 LSU). Comparing ES and NS, for UT task, ES had significantly greater task scores (570 [563-648] vs 323 [130-464], p value 0.00036) and GOALS scores (14 [13-16] vs 10 [8-12], p value 0.0038). Similarly, for CS, ES had significantly greater task scores (976 [959-1010] vs 785 [626-856], p value 0.00009) and GOALS scores (16 [12-17] vs 12.5 [8.25-15], p value 0.028). After FFTs were developed, comparing ES and NS, for both UT and CS tasks, ES had significantly greater FFT scores (UT 25 [24-26] vs 17 [14-20], p value 0.0016 and CS 30 [27-32] vs 22[17.2-25.8], p value 0.00061). CONCLUSION: In conclusion, preliminary validity evidence was provided for the tasks. Once further validity evidence is established, incorporating the tasks into the training curricula could improve trainee skills and help to meet the need for better advanced suturing models.

BACKGROUND: Transanal total mesorectal excision (TATME) is difficult to learn and can result in serious complications. Current paradigms for assessing performance and competency may be insufficient. This study aims to develop and provide preliminary validity evidence for a TATME virtual assessment tool (TATME-VAT) to assess the cognitive skills necessary to safely complete TATME dissection. METHODS: Participants from North America, Europe, Japan and China completed the test via an interactive online platform between 11/2019 and 05/2020. They were grouped into expert, experienced and novice surgeons depending on the number of independently performed TATMEs. TATME-VAT is a 24-item web-based assessment evaluating advanced cognitive skills, designed according to a blueprint from consensus guidelines. Eight items were multiple choice questions. Sixteen items required making annotations on still frames of TATME videos (VCT) and were scored using a validated algorithm derived from experts' responses. Annotation (range 0-100), multiple choice (range 0-100), and overall scores (sum of annotation and multiple-choice scores, normalized to µ = 50 and σ = 10) were reported. RESULTS: There were significant differences between the expert, experienced, and novice groups for the annotation (p < 0.001), multiple-choice (p < 0.001), and overall scores (p < 0.001). The annotation (p = 0.439) and overall (p = 0.152) scores were similar between the experienced and novice groups. Annotation scores were higher in participants with 51 or more vs. 30-50 vs. less than 30 cases. Scores were also lower in users with a self-reported recent complication vs. those without. CONCLUSIONS: This study describes the development of an interactive video-based virtual assessment tool for TATME dissection and provides initial validity evidence for its use.

INTRODUCTION: Transanal total mesorectal excision (TaTME) is technically challenging even for experienced colorectal surgeons and there may be a higher risk of complications during learning. Determining when a surgeon is ready to safely perform this technique independently remains a matter of debate. Therefore, the objective of this study was to systematically summarize the available evidence regarding measures of proficiency in TaTME for rectal adenocarcinoma. METHODS: A systematic search of MEDLINE, Embase, PubMed Epub records, Biosis previews, Scopus, and Cochrane Library databases was performed according to PRISMA guidelines. All English and French language studies published between 2010 and 2018 that described proficiency metrics for TaTME were included. Study heterogeneity precluded meta-analysis, and therefore qualitative synthesis was performed. The primary outcomes were the methodology and measures used to define proficiency, and the number of cases needed to achieve proficiency. RESULTS: Of 994 citations, five studies met inclusion criteria. Of these, only two used objective measures to define proficiency. These studies evaluated patient outcomes and defined proficiency through cumulative sum (CUSUM) analysis of the primary outcome(s): post-operative complications and TME quality. Two studies reported expert consensus to establish recommendations using a combination of electronic survey distributed to colorectal surgeons and consensus conferences with TaTME experts from 7 to 8 different countries. One study defined the learning phase as 16 months of TaTME practice, or the first 27 cases. Stated case volumes needed to achieve proficiency varied widely. Studies using objective outcome measures reported threshold volumes of 40 and 51 cases, respectively, while expert consensus studies recommended needing 6-30 procedures. CONCLUSIONS: Significant heterogeneity exists regarding the determination of proficiency benchmarks for TaTME. Expert consensus documents recommend lower case numbers to obtain proficiency than those defined by objective measures, suggesting greater experience may be required than generally thought.

BACKGROUND: Despite a need for assessment of endoscopic submucosal dissection (ESD) skills in order to track progress and determine competence, there is no structured measure of assessing competency in ESD performance. The present study aims to develop and examine validity evidence for an assessment tool to evaluate the recorded performance of ESD for gastric neoplasms. METHODS: The ESD video assessment tool (EVAT) was systematically developed by ESD experienced endoscopists. The EVAT consists of a 25-item global rating scale and 3-item checklist to assess competencies required to perform ESD. Five unedited videos were each evaluated by 2-blinded experienced ESD endoscopists to assess inter-rater reliability using intraclass correlation coefficients (ICC). Seventeen unedited videos in total were rated by 3 blinded experienced ESD endoscopists. Validity evidence for relationship to other variables was examined by comparing scores of inexperienced (fellows) and experienced endoscopists (attending staff), and by evaluating the relationship between the EVAT scores and ESD case experience. Internal consistency was evaluated using Cronbach's alpha. RESULTS: The inter-rater reliability for the total score was high at 0.87 (95% confidence interval 0.11 to 0.99). The total score [median, interquartile range (IQR)] was significantly different between the inexperienced (71, 63-77) and experienced group (95, 91-97) (P = 0.005). The total scores demonstrated high correlation with the number of ESD cases (Spearman's ρ = 0.79, P < 0.01). The internal consistency was 0.97. CONCLUSIONS: This study provides preliminary validity evidence for the assessment of video-recorded ESD performances for gastric neoplasms using EVAT.

INTRODUCTION: Incisional negative pressure wound therapy (iNPWT) may reduce surgical site infections (SSI), which can have devastating consequences after incisional hernia repair. Few comparative studies investigate the effectiveness of this wound management strategy in this population. The objective of this study is to determine the effect of iNPWT on the incidence of SSI after complex incisional hernia repair. METHODS: All adult patients undergoing open incisional hernia repair at a single center from 2016 to 2019 were reviewed. A commercial iNPWT dressing was used at the discretion of the surgeon. Patients were grouped by type of dressing; iNPWT and standard sterile dressings (SSD). Coarsened exact matching was used to create balanced cohorts for comparison using age, sex, American Society of Anesthesiologists classification, wound classification, and surgical urgency. The primary outcome was the composite incidence of superficial and deep SSI within 30 days. Secondary outcomes included non-infectious surgical site occurrences (SSO), overall complications, length of stay (LOS), emergency department visits, and readmission at 30 days. RESULTS: 134 patients underwent complex hernia repair, with 114 patients included after matching (34 iNPWT, 51 SSD). Composite incidence of superficial and deep SSI was 19.3% (11.8% vs. 27.5%, p = 0.107), with significantly lower rates of deep SSI in patients receiving iNPWT (2.9% vs. 17.6%, p = 0.045). After accounting for residual differences between groups, iNPWT was associated with decreased incidence of composite SSI (RR 0.36, 95% CI [0.16, 0.87]). Median LOS was longer in patients with iNPWT (7 vs. 5 days, p = 0.001). There were no differences in SSO, overall complications, readmission, or emergency department visits. CONCLUSION: In patients undergoing incisional hernia repair, the use of iNPWT was associated with a lower incidence of SSI at 30 days. Future studies should focus on cost effectiveness of iNPWT, its impact on long-term hernia recurrences, and the identification of patient selection criteria in this population.

BACKGROUND: Postoperative ileus (POI) is common after gastrointestinal surgery and is associated with significant morbidity and costs. However, POI is poorly defined. The I-FEED score is a novel outcome measure for POI, developed by expert consensus. It contains five elements (intake, response to nausea treatment, emesis, exam, and duration, each scored with 0, 1, or 3 points) and classifies patients into normal, postoperative gastrointestinal intolerance (POGI), and postoperative gastrointestinal dysfunction (POGD). However, it has not yet been validated in a clinical context. The objective was to provide validity evidence for the I-FEED score to measure the construct of POI in patients undergoing colorectal surgery. METHODS: Data previously collected from a clinical trial investigating the impact of different perioperative fluid management strategies on primary POI in patients undergoing elective laparoscopic colectomy (2013-2015) were analyzed. Patients were managed by a longstanding Enhanced Recovery program (expected length of stay (LOS): 3 days). Daily I-FEED scores were generated (normal 0-2, POGI 3-5, POGD 6+ points) up to hospital discharge or postoperative day 7. Validity was assessed by testing the hypotheses that I-FEED score was higher (1) in patients with longer time to GI3 (tolerating diet + flatus/bowel movement), (2) with longer LOS (> 3 days vs shorter), (3) in patients with complications vs without, (4) in patients with poorer recovery (measured by Quality of Recovery-9 questionnaire). RESULTS: A total of 128 patients were included for analysis (mean age 61.7 years (SD 15.2), 57% male, 71% malignancy, and 39.1% rectal resection). Median LOS was 4 days [IQR3-5], and 32% experienced postoperative in-hospital morbidity. Overall, 48% of patients were categorized as normal, 22% POGI, and 30% POGD. The data supported all 4 hypotheses. CONCLUSIONS: This study contributes preliminary validity evidence for the I-FEED score as a measure for POI after colorectal surgery.

INTRODUCTION: Delayed gastrointestinal (GI) recovery remains a significant morbidity after colorectal surgery. Intracorporeal anastomosis for right colectomy may hasten GI recovery. Therefore, the objective of this study was to determine the effect of intracorporeal versus extracorporeal anastomosis on GI recovery after elective laparoscopic right colectomy within an established ERAS program. METHODS: Adult patients undergoing elective laparoscopic right colectomy at a single high-volume institution from 07/2014 to 12/2018 were reviewed. Patients were divided into two groups: intracorporeal (IC) and extracorporeal (EC). The primary outcome was time to GI-3 defined as days to tolerance of solid diet and first flatus/bowel movement. Prolonged postoperative ileus (PPOI) was defined as GI-3 not met by postoperative day 4. Secondary outcomes were length of stay (LOS) and overall 30-day complications. Sensitivity analysis was performed using coarsened exact matching to account for unmeasured confounding. Multiple regression was performed using a Cox proportional hazard model to identify predictors of GI recovery. RESULTS: A total of 346 patients were reviewed, of which 226 were included (71IC, 155EC). Patient characteristics were well balanced between groups: mean age was 64.9 years (SD 15.9), BMI was 26.3 (SD 5.7), 38.1% of patients had ASA ≥ 3, and 78.3% underwent surgery for neoplasms. IC anastomosis was associated with longer operative duration (165 min (SD 40); 144 min (SD 48), p = 0.002). There was no difference in the median time to GI-3 (IC 2 days [IQR1-2]; EC 2 days [IQR2-3], p = 0.135). The incidence of PPOI (IC 8.5%; EC 10.3%, p = 0.659), superficial SSI (4.2% vs. 5.8%, p = 0.757), deep SSI (2.8% vs. 5.2%, p = 0.729), and median LOS (3 days [IQR 2-4] vs. 3 [IQR 3-5], p = 0.059) were also similar. On multivariate analysis, IC anastomosis did not independently predict faster GI recovery (HR 0.98, 95% CI 0.71-1.34). Similar results were observed in the matched cohort (185 patients (61IC, 124EC)). CONCLUSION: In this study, IC anastomosis was not associated with faster GI recovery or reduced complication rate compared to EC anastomosis. Longer term studies may be required to determine the potential benefits of IC anastomosis.

INTRODUCTION: Repair of giant paraesophageal hernia (PEH) has historically been associated with significant morbidity and mortality such that elective repair is only offered to symptomatic patients. Recent reports suggest modern era outcomes have improved such that elective repair may now be safer than historically thought. Furthermore, the morbidity of emergency surgery may still be significant. These changes may have important implications for patient selection for elective repair. The objectives of this study were to determine and compare modern era surgical outcomes after elective and emergency repair of giant PEHs at a high-volume tertiary care center. METHODS: A retrospective review was conducted for all Type II-IV giant PEH repairs performed between 1 January 2012 and 31 December 2017. Type 1 hiatal hernias, fundoplication for reflux, and any co-surgery other than cholecystectomy were excluded from the final analysis. Baseline patient demographics, operative details, postoperative complications within 30 days and in-hospital or 30-day mortality were tabulated from the electronic medical record. Data were reported as median (interquartile range) unless otherwise specified. RESULTS: A total of 352 cases were reviewed, of which 204 met inclusion criteria (18 emergency, 186 elective). Eight had Type II PEH, 146 had Type III, and 50 had Type IV. Median length of stay was shorter in the elective group [1 (1) day elective vs. 5 (7) days emergency, p < 0.0001], and emergency patients were less likely to return directly to their original residence at discharge (13, 72% emergency vs 185, 99.4% elective, p < 0.0001). There were significantly more major complications (Clavien-Dindo score ≥ 3) in the emergency group (5, 28% emergency vs. 10, 5% elective, p = 0.005). There were no perioperative deaths in either group. Morbidity and mortality in both groups were less than historically reported. CONCLUSIONS: Informed consent discussions and patient selection for repair of giant PEHs should reflect modern era and institution-specific outcomes.

BACKGROUND: Increased adherence with enhanced recovery pathways (ERP) is associated with improved outcomes. However, adherence to postoperative elements that rely on patient participation remains suboptimal. Mobile device apps may improve delivery of health education material and have the potential to foster behavior change and improve patient compliance. The objective of this study was to estimate the extent to which a novel mobile device app affects adherence to an ERP for colorectal surgery in comparison to standard written education. METHODS: This was a superiority, parallel-group, assessor-blind, sham-controlled randomized trial involving 97 patients undergoing colorectal resection. Participants were randomly assigned with a 1:1 ratio into one of two groups: (1) iPad including a novel mobile device app for postoperative education and self-assessment of recovery, or (2) iPad without the app. The primary outcome measure was mean adherence (%) to a bundle of five postoperative ERP elements requiring patient participation: mobilization, gastrointestinal motility stimulation, breathing exercises, and consumption of oral liquids and nutritional drinks. RESULTS: In the intervention group, app usage was high (94% completed surveys on POD0, 82% on POD1, 72% on POD2). Mean overall adherence to the bundle on the two first postoperative days was similar between groups: 59% (95% CI 52-66%) in the intervention group and 62% (95% CI 56-68%) in the control group [Adjusted mean difference 2.4% (95% CI - 5 to 10%) p = 0.53]. CONCLUSIONS: In this randomized trial, access to a mobile health application did not improve adherence to a well-established enhanced recovery pathway in colorectal surgery patients, when compared to standard written patient education. Future research should evaluate the impact of applications integrating novel behavioral change techniques, particularly in contexts where adherence is low.
