RESUMEN
OBJECTIVE: We sought to compare long-term healthcare dependency and time-at-home between older adults undergoing minimally invasive surgery (MIS) for colorectal cancer (CRC) and those undergoing open resection. BACKGROUND: Although the benefits of MIS for CRC resection are established, data specific to older adults are lacking. Long-term functional outcomes, central to decision-making in the care for older adults, are unknown. METHODS: We performed a population-based analysis of patients ≥70years old undergoing CRC resection between 2007 to 2017 using administrative datasets. Outcomes were receipt of homecare and "high" time-at-home, which we defined as years with ≤14 institution-days, in the 5years after surgery. Homecare was analyzed using time-to-event analyses as a recurrent dichotomous outcome with Andersen-Gill multivariable models. High timeat-home was assessed using Cox multivariable models. RESULTS: Of 16,479 included patients with median follow-up of 4.3 (interquartile range 2.1-7.1) years, 7822 had MIS (47.5%). The MIS group had lower homecare use than the open group with 22.3% versus 31.6% at 6 months and 14.8% versus 19.4% at 1 year [hazard ratio 0.87,95% confidence interval (CI) 0.83-0.92]. The MIS group had higher probability ofhigh time-at-home than open surgery with 54.9% (95% CI 53.6%-56.1%) versus 41.2% (95% CI 40.1%-42.3%) at 5years (hazard ratio 0.71, 95% CI 0.68-0.75). CONCLUSIONS: Compared to open surgery, MIS for CRC resection was associated with lower homecare needs and higher probability of high time-at-home in the 5 years after surgery, indicating reduced long-term functional dependence. These are important patient-centered endpoints reflecting the overall long-term treatment burden to be taken into consideration in decision-making.

INTRODUCTION: Transanal total mesorectal excision (taTME) is a novel approach to surgery for rectal cancer. The technique has gained significant popularity in the surgical community due to the promising ability to overcome technical difficulties related to the access of the distal pelvis. Recently, Norwegian surgeons issued a local moratorium related to potential issues with the safety of the procedure. Early adopters of taTME in Canada have recognized the need to create guidelines for its adoption and supervision. The objective of the statement is to provide expert opinion based on the best available evidence and authors' experience. METHODS: The procedure has been performed in Canada since 2014 at different institutions. In 2016, the first Canadian taTME congress was held in the city of Toronto, organized by two of the authors. In early 2019, a multicentric collaborative was established [The Canadian taTME expert Collaboration] which aimed at ensuring safe performance and adoption of taTME in Canada. Recently surgeons from 8 major Canadian rectal cancer centers met in the city of Toronto on December 7 of 2019, to discuss and develop a position statement. There in person, meeting was followed by 4 rounds of Delphi methodology. RESULTS: The generated document focused on the need to ensure a unified approach among rectal cancer surgeons across the country considering its technical complexity and potential morbidity. The position statement addressed four domains: surgical setting, surgeons' requirements, patient selection, and quality assurance. CONCLUSIONS: Authors agree transanal total mesorectal excision is technically demanding and has a significant risk for morbidity. As of now, there is uncertainty for some of the outcomes. We consider it is possible to safely adopt this operation and obtain adequate results, however for this purpose it is necessary to meet specific requirements in different domains.

OBJECTIVE: To present the technique for and early results of laparoscopic intragastric resection (LIGR). BACKGROUND: Treatment of confirmed or suspected submucosal gastric malignancies relies on clear margin resection, for which minimally invasive surgery is widely accepted. However, resection in some localization remains challenging. METHODS: We present the steps of LIGR for gastric submucosal tumors (GSMTs). We report the results of LIGR in consecutive patients operated at 2 institutions, including intraoperative, pathologic, 30-day major morbidity and mortality characteristics. RESULTS: After laparoscopic access to the abdominal cavity, cuffed gastric ports are placed to approximate the anterior gastric wall to the abdominal wall. A pneumogastrum is created. The tumor is resected in the submucosal plane and the deficit closed with intragastric suturing. Specimen extraction is performed perorally or through a gastrotomy site. In 8 proximal intraluminal GSMTs with median size of 3.1 cm (range: 1.8-6.0 cm), median operative time was 167.5 minutes (range: 120-300 mins). There was no major morbidity and no mortality. All resections were R0. CONCLUSIONS: We illustrate the technique of a novel, feasible, and safe minimally invasive approach to GSMTs. LIGR is an alternative to resect challenging GSMTs by limiting surgical invasiveness and preserving gastrointestinal function.

BACKGROUND: The extra-levator approach to abdominal perineal resection (APR) was developed in order to reduce the rates of positive circumferential resection margin. This approach, however, is associated with significant morbidity. We postulate that a less radical resection of the levators done laparoscopically could significantly decrease the rate of perineal complications while ensuring an oncologically adequate specimen. To date, to our knowledge, there are no reports in the literature describing a laparoscopic translevator approach for APR. The purpose of this study is to describe our initial experience with this approach and assess our short-term oncologic and clinical outcomes. METHODS: This is a retrospective study of patients who underwent laparoscopic APR with intra-abdominal levator transection for rectal cancer from 2012 to 2014 at a single tertiary care institution. Main outcome measures include: perineal flap rates, post-operative complications, length of stay, distance from tumour to circumferential resection margin, R0 status, and disease recurrence. Data are presented as median (interquartile range) unless otherwise noted. RESULTS: Seventeen cases were identified. Patient age was 61 (range 34-75), and 59 % were male. Pre-operative distance of the tumour from the anal verge was 2.6 cm (0.4-3.9). Post-operative length of stay was 4 (4-6) days. One patient required a perineal flap for reconstruction. Four patients (22 %) had perineal complications (three wound infections and one hernia). No patients reported sexual dysfunction, and one (5 %) developed urinary retention. Five (29 %) patients had a complete pathological response. The circumferential resection margin was 1.5 (0.8-2.5) cm, with no positive margins reported. The number of retrieved lymph nodes was 12 (range 2-30). Follow-up was 9.7 months (range 20 days-23 months), during which one patient developed recurrent disease. CONCLUSIONS: This study describes a novel surgical approach to APR that has the potential to both decrease perineal complications and provide excellent oncologic results.

The inaugural Early-Age-Onset Colorectal Cancer Symposium was convened in June 2021 to discuss the implications of rapidly rising rates of early-age-onset colorectal cancer (EAO-CRC) in Canadians under the age of 50 and the impactful outcomes associated with this disease. While the incidence of CRC is declining in people over the age of 50 in Canada and other developed countries worldwide, it is significantly rising in younger people. Canadians born after 1980 are 2 to 2.5 times more likely to be diagnosed with CRC before the age of 50 than previous generations at the same age. While the etiology of EAO-CRC is largely unknown, its characteristics differ in many key ways from CRC diagnosed in older people and warrant a specific approach to risk factor identification, early detection and treatment. Participants of the symposium offered directions for research and clinical practice, and developed actionable recommendations to address the unique needs of these individuals diagnosed with EAO-CRC. Calls for action emerging from the symposium included: increased awareness of EAO-CRC among public and primary care practitioners; promotion of early detection programs in younger populations; and the continuation of research to identify unique risk factor profiles, tumour characteristics and treatment models that can inform tailored approaches to the management of EAO-CRC.

OBJECTIVE: To determine the efficacy and safety of extended duration perioperative thromboprophylaxis by low molecular weight heparin when assessing disease-free survival in patients undergoing resection for colorectal cancer. DESIGN: Multicentre, open label, randomised controlled trial. SETTINGS: 12 hospitals in Quebec and Ontario, Canada, between 25 October 2011 and 31 December 2020. PARTICIPANTS: 614 adults (age ≥18 years) were eligible with pathologically confirmed invasive adenocarcinoma of the colon or rectum, no evidence of metastatic disease, a haemoglobin concentration of ≥8 g/dL, and were scheduled to undergo surgical resection. INTERVENTIONS: Random assignment to extended duration thromboprophylaxis using daily subcutaneous tinzaparin at 4500 IU, beginning at decision to operate and continuing for 56 days postoperatively, compared with in-patient postoperative thromboprophylaxis only. MAIN OUTCOME MEASURES: Primary outcome was disease-free survival at three years, defined as survival without locoregional recurrence, distant metastases, second primary (same cancer), second primary (other cancer), or death. Secondary outcomes included venous thromboembolism, postoperative major bleeding complications, and five year overall survival. Analyses were done in the intention-to-treat population. RESULTS: The trial stopped recruitment prematurely after the interim analysis for futility. The primary outcome occurred in 235 (77%) of 307 patients in the extended duration group and in 243 (79%) of 307 patients in the in-hospital thromboprophylaxis group (hazard ratio 1.1, 95% confidence interval 0.90 to 1.33; P=0.4). Postoperative venous thromboembolism occurred in five patients (2%) in the extended duration group and in four patients (1%) in the in-hospital thromboprophylaxis group (P=0.8). Major surgery related bleeding in the first postoperative week was reported in one person (<1%) in the extended duration and in six people (2%) in the in-hospital thromboprophylaxis group (P=0.1). No difference was noted for overall survival at five years in 272 (89%) patients in the extended duration group and 280 (91%) patients in the in-hospital thromboprophylaxis group (hazard ratio 1.12; 95% confidence interval 0.72 to 1.76; P=0.1). CONCLUSIONS: Extended duration to perioperative anticoagulation with tinzaparin did not improve disease-free survival or overall survival in patients with colorectal cancer undergoing surgical resection compared with in-patient postoperative thromboprophylaxis alone. The incidences of venous thromboembolism and postoperative major bleeding were low and similar between groups. TRIAL REGISTRATION: ClinicalTrials.gov NCT01455831.

BACKGROUND: Pancreatic adenocarcinoma (PA) is largely incurable, although recent progress has been made in the safety of surgery for PA and in adjuvant and palliative chemotherapy. The purpose of this study was to describe the management of PA in Ontario, Canada. METHODS: The Pathology Information Management System (PIMS), which uses electronic pathology reporting (E-path), was used to rapidly identify and recruit patients based on a pathologic diagnosis of PA between 2003 and 2006. Patients were mailed questionnaires for additional data. RESULTS: The patient participation rate was 26% (351 of 1325). Nonresponders were more likely to be older than 70 years (43% v. 28%, p < 0.001) and to have received treatment in nonacademic centres (53% v. 34%, p < 0.001). Fifty-four percent of responders underwent a potentially curative operation, and most (77%) were 70 years or younger (p = 0.03). Completed resections were documented in 83% of patients who underwent exploratory surgery with curative intent; 17% of patients had unresectable and/or metastatic disease at laparotomy. Of the completed resections, 24% were performed in nonacademic centres with a 32% positive margin rate; 76% were performed in academic centres with a 29% positive margin rate (p = 0.84). Resections with curative intent were less frequently aborted in academic centres (10% v. 33%, p < 0.001). Of the patients who responded to our questionnaire, 43% received chemotherapy and 7% participated in clinical trials. CONCLUSION: Despite using PIMS and E-path, the response rate for this study was low (< 30%). Nonresponders were older and more commonly treated in nonacademic centres. Patients undergoing surgery in academic centres had higher resection rates. The rate of adjuvant and palliative chemotherapy was stage-dependent and low.

Thirty percent of colon cancer diagnoses occur following emergency presentations, often with bowel obstruction or perforation requiring urgent surgery. We sought to compare cancer care quality between patients receiving emergency versus elective surgery. We conducted an institutional retrospective matched (46 elective:23 emergency; n = 69) case control study. Patients who underwent a colon cancer resection from January 2017 to February 2019 were matched by age, sex, and cancer stage. Data were collected through the National Surgical Quality Improvement Program and chart review. Process outcomes of interest included receipt of cross-sectional imaging, CEA testing, pre-operative cancer diagnosis, pre-operative colonoscopy, margin status, nodal yield, pathology reporting, and oncology referral. No differences were found between elective and emergency groups with respect to demographics, margin status, nodal yield, oncology referral times/rates, or time to pathology reporting. Patients undergoing emergency surgery were less likely to have CEA levels, CT staging, and colonoscopy (p = 0.004, p = 0.017, p < 0.001). Emergency cases were less likely to be approached laparoscopically (p = 0.03), and patients had a longer length of stay (p < 0.001) and 30-day readmission rate (p = 0.01). Patients undergoing emergency surgery receive high quality resections and timely post-operative referrals but receive inferior peri-operative workup. The adoption of a hybrid acute care surgery model including short-interval follow-up with a surgical oncologist or colorectal surgeon may improve the quality of care that patients with colon cancer receive after acute presentations. Surgeons treating patients with colon cancer emergently can improve their care quality by ensuring that appropriate and timely disease evaluation is completed.

INTRODUCTION: Resection for isolated distant recurrence of colon cancer is well accepted. Resection for locoregionally recurrent colon cancer (LRCC) is not well studied. We evaluated the long-term outcomes of curative-intent resection for LRCC. METHODS: All patients undergoing curative-intent resection for LRCC at three specialized cancer centers affiliated with the University of Toronto were identified (1993-2017). Follow-up included serial clinical assessment, colonoscopy, CEA, and cross-sectional imaging. Overall survival (OS), cancer-specific survival (CSS) and time to re-recurrence were estimated using Kaplan-Meier method and cumulative incidence function. The association between resection margins and outcome was assessed with Cox models. RESULTS: 117 patients were included in the study cohort. Median follow-up was 53 months (IQR: 34-101). OS was 75% (95% CI: 68-84) at 5 years, and 69% (95% CI: 59-79) at 10 years. CSS was 78% (95% CI: 70-86) at 5 years and 72% (95% CI: 63-83) at 10 years. The rate of re-recurrence was 22% (95% CI: 14-31) at 5 years, and 27% (95% CI: 16-39) at 10 years. Negative resection margin (R0) was associated with improved OS (HR 3.33, 95% CI: 1.85-6.00, p < 0.01). There were no postoperative deaths; complications with Clavien-Dindo grade > II occurred in 12% of patients. Perioperative chemotherapy was used in 63% of patients and radiotherapy in 37%. CONCLUSION: In selected patients with LRCC, excellent OS, CSS and low re-recurrence rates were observed, and R0 resection predicted better outcomes. These findings support consideration of resection for LRCC in fit patients after review at a multidisciplinary cancer conference.

Importance: Proponents of novel transanal total mesorectal excision (TME) suggest the procedure overcomes the technical and oncologic challenges of conventional approaches for treating rectal cancer. Recently, however, there has been controversy regarding the oncologic safety of the procedure. Objective: To assess the association of transanal TME with the incidence of local recurrence (LR) of cancer and the probability of remaining free of LR during follow-up. Design, Setting, and Participants: This multicenter cohort study used data from 8 high-volume rectal cancer academic institutions from across Canada on all consecutive patients with primary rectal cancer treated by transanal TME at the participating centers. The study was conducted between January 2014 and December 2018, and data were analyzed from April 1, 2020, to September 15, 2020. Exposure: Transanal TME. Main Outcomes and Measures: The incidence of LR was reported as a direct measure of quality of resection. The cumulative probability of LR- and systemic recurrence (SR)-free survival at 36 months was estimated. Local recurrence and SR were defined as radiologic or endoscopic evidence of 1 or more new lesions in or outside the pelvis, respectively, documented during surveillance after the removal of the primary tumor. Results: Of 608 total patients included in the analysis, 423 (69.6%) were male; the median age was 63 years (interquartile range [IQR], 54-70 years). Local recurrence was identified in 22 patients (3.6%) after a median follow-up of 27 months (IQR, 18-38 months). The median time to LR was 13 months (IQR, 9-19 months). Sixteen of the 22 patients with LR (72.7%) were male, 14 (63.6%) received neoadjuvant chemoradiation, and 12 (54.5%) had American Joint Committee on Cancer stage III disease. Of those with LR, 16 (72.7%) had a negative circumferential radial margin and 20 (90.9%) had a negative distal resection margin, 2 (9.1%) experienced conversion to open surgery, and 15 (68.2%) also developed SR. The probability of LR-free survival at 36 months was 96% (95% CI, 94%-98%). According to the Cox proportional hazards regression model, the hazard ratio of LR was estimated to be 4.2 (95% CI, 2.9-6.2) times higher among patients with a positive circumferential radial margin than among those with a negative circumferential radial margin. Conclusions and Relevance: In this cohort study, transanal TME performed by experienced surgeons was associated with an incidence of LR and SR that is in line with the published literature on open and laparoscopic TME, suggesting that transanal TME may be an acceptable approach for management of rectal cancer.

INTRODUCTION: Chemoradiation (CRT) with intensity modulated radiation treatment (IMRT) has become the standard for anal cancer. In patients who fail this treatment modality, salvage surgery with abdominal perineal resection can result in long term cancer control. We aimed to evaluate a single centre's experience of salvage surgery for local recurrence since the introduction of IMRT. MATERIALS AND METHODS: A retrospective chart review was performed of all patients who underwent definitive CRT for anal carcinoma at a single tertiary referral center since IMRT became standard in 2009. Patients with recurrent or persistent disease after treatment who underwent salvage surgery were included. Details of CRT, salvage surgery and surgical complications, patterns of recurrence after surgery, and survival data were collected and described. RESULTS: Between 2009-2018, 181 patients underwent definitive treatment using IMRT for anal carcinoma. Of 26 patients who had locoregional recurrent or persistent disease, 14 underwent salvage surgery. Nine had multi-visceral resection and 8 required autologous flap reconstruction. Twelve patients had resections with clear margins and 2 had microscopic positive margins. Twelve patients (86%) experienced post-operative complications, and eight (57%) had perineal wound complications. After salvage, four patients (29%) recurred locally. None of the 8 patients with rpT2 disease recurred. After salvage surgery, 5-year disease free survival was 68.4% and 5-year overall survival was 75%. CONCLUSION: Following IMRT based chemoradiation, salvage surgery has high rates of surgical complications; however disease free and overall survival results are excellent particularly for small recurrences.

BACKGROUND: Transanal total mesorectal excision can be a technically challenging operation to master. While many early adopters have reported adequate outcomes, others have failed to reproduce these results. There are contradicting data on oncologic outcomes during the learning phase of this technique. Thus, our objective was to perform a multicentered assessment of oncological outcomes in patients undergoing transanal total mesorectal excision during the learning phase in a sample of successful adopting centers. METHODS: Surgeons from 8 centers with experience in the management of rectal cancer were invited to participate. The initial 51 consecutive benign and malignant cases of the participating units were retrospectively reviewed, but only 366 cancer cases were included in the analysis. Procedures were divided into implementation (ie, the first 10 cases) and postimplementation (ie, case 11 on onwards) groups, and the main outcome was the incidence of local recurrence. RESULTS: The overall prevalence of local recurrence was 4.1% at a median follow-up of 35 months (interquartile range 20.3-44.2); among implementation and postimplementation groups local recurrence was 7.5% and 3.1%, respectively, and the rate of local recurrence was observed to be nearly 60% lower in the postimplementation group (hazard ratio [95% confidence interval] = 0.43 [0.26-0.72]) Total mesorectal excision specimens were complete or nearly complete in 87.7% of cases, and the circumferential and distal margins were clear in 93.2% and 92.6%, respectively CONCLUSION: Local recurrence rate was low during the learning phase of the transanal total mesorectal excision in a sample of rectal cancer surgeons with acceptable surgical and oncologic outcomes. Both the prevalence and rate of local recurrence were markedly lower in the postimplementation phase, indicating improvement as experience accumulated.

Unlike intraperitoneal colorectal injuries, the standard of care for extraperitoneal rectal trauma includes a diverting colostomy due to relative inaccessibility of these injuries for primary repair. New technologies to enhance access to the extraperitoneal rectum have gained increasing use in benign and malignant rectal disease. We present two cases of low-velocity penetrating extraperitoneal rectal trauma. In both cases, a transanal minimally invasive surgery (TAMIS) approach was used to access, and primarily repair, full-thickness rectal lacerations. These patients were successfully managed without a colostomy and without complication. TAMIS enables access to distal rectal injuries, facilitating primary repair and bringing the management of extraperitoneal rectal injuries in line with intraperitoneal injuries, with the potential to avoid fecal diversion.
RESUMEN
INTRODUCTION: A comprehensive proficiency-based curriculum for an advanced, minimally invasive procedure was previously developed and shown to be more educationally effective than conventional surgery training. OBJECTIVE: To implement and evaluate this proficiency-based curriculum in 2 academic general surgery residency programs in Canada. SETTING: Two academic, general surgery residency programs at university hospitals in Ontario, Canada. METHODS: An 8-week, proficiency-based curriculum consisted of a didactic component (lectures, small group sessions, assigned readings) and a simulation-based component (proficiency-based training in laparoscopic enteroenterostomy and a simulated operating room crisis scenario). It was offered to postgraduate years 2-5 general surgery residents in 2 academic programs in Canada. Pre- and postcurriculum procedure-specific knowledge and psychomotor skills were assessed using a 25-item knowledge test and a procedure-specific assessment scale. Postcurriculum nontechnical skills were assessed using the Nontechnical Skills for Surgeons scale. Participants' perceptions about the curriculum were assessed using a questionnaire. Direct costs for curriculum implementation were recorded. RESULTS: Twenty-five residents participated in the curriculum across 2 programs. Completion of the curriculum resulted in significant improvement in technical skills (45 [37.5-65] versus 88 [85-93]; P < .01) and demonstration of "acceptable" situational awareness (3 [3-4]), decision-making (3 [3-4]), teamwork and communication (3 [2-4]), and leadership (3 [3-4]) skills. There was no improvement in procedure-specific knowledge (48 [40-64] versus 58 [48-60]; P = .39). Participants perceived all components of the curriculum as educationally valuable, and 96% agreed and/or strongly agreed that this curriculum should continue to be a part of academic curriculum. The average cost of curriculum implementation was $613.05 Canadian dollars per participant. Lack of faculty supervision was the main barrier to implementation with only 65% of participants agreeing and/or strongly agreeing that quantity of faculty supervision was optimal. CONCLUSIONS: A comprehensive proficiency-based curriculum for an advanced, minimally invasive procedure was successfully implemented and evaluated at 2 academic general surgery residency programs in Canada. Adequate faculty preceptor resources are essential for widespread implementation.

BACKGROUND: Preliminary evidence suggests that coaching is an effective adjunct in resident training. The learning needs of faculty, however, are different from those of trainees. Assessing the effectiveness of peer coaching at improving the technical proficiency of practicing surgeons is an area that remains largely unexplored. The purpose of this study was to assess the efficacy of a peer coaching program that teaches laparoscopic suturing to faculty surgeons. METHODS: Surgeons inexperienced in laparoscopic suturing were randomized to either conventional training or peer coaching. Both groups performed a pretest on a box trainer. The conventional training group then received a web link to a tutorial for teaching laparoscopic suturing and a box trainer for independent practice. In addition to the web link and the box trainer, the peer coaching group received 2 half hour peer coaching sessions. Both groups then performed a stitch on the box trainer that was video recorded. The primary outcome measure was technical performance, which was assessed by a global rating scale. RESULTS: Eighteen faculty were randomized (conventional training n = 9; peer coaching n = 9). Initially, there was no difference in technical skills between the groups (conventional training median score 10 [interquartile range 8.5-15]; peer coaching 13 [10.5-14]; P = .64). After the intervention, the peer coaching group had improved technical performance (conventional training 11 [8.5-12.5]; peer coaching 18 [17-19]; P < .01). Comparing the pre- and postintervention scores within both groups, there was an improvement in technical proficiency in the peer coaching group, yet none in the conventional training group (before conventional training 10 [8.5-15], after conventional training 11 [8.5-12.5]; P = .56; before peer coaching 13 [10.5-14], after peer coaching 18 [17-19]; P < .01). CONCLUSION: This trial demonstrates that a structured peer coaching program can facilitate faculty surgeons learning a novel procedure.

INTRODUCTION: Overall, 25% of American general surgery residents identified as not feeling confident operating independently at graduation, which may contribute to 70% pursuing further training. This study was undertaken to identify intended career plans of general surgery graduates in Canada on a national level, and perceived strengths and weaknesses of training that would affect transition to early practice. METHODS: Questionnaires were distributed to graduating general surgery residents at a Canadian national review course in 2012 and 2013. Data were analyzed for overall trends. RESULTS: Overall, 75% (78/104) of graduating residents responded in 2012 and 53% (50/95) in 2013. Greater than 60% of respondents were entering a fellowship program upon graduation (49/78 in 2012 and 37/50 in 2013); the most common fellowship choices were minimally invasive surgery (24% in 2012 and 39% in 2013) or surgical oncology (16% in 2012). Most residents reported that they were completing subspecialty training to meet career goals (64/85 overall) rather than feeling unprepared for practice (0/85 overall). Most residents planned on practicing in urban centers (54%) and academic hospitals (73%). Residents perceived a need for assistance for laparoscopic adrenalectomy, neck dissection, laparoscopic splenectomy, laparoscopic low anterior resection, groin dissection, and thyroidectomy. CONCLUSIONS: An overwhelming majority of general surgery graduates plan to pursue fellowship training to meet career goals of working in urban, academic centers, rather than a perceived lack of competence. It is vital to describe operative competency expectations for residents and to promote a variety of practice opportunities following graduation.
