Marginal ulcer continues to be a major source of morbidity over time following gastric bypass.

BACKGROUND: Marginal ulcerations (MU) are a common and concerning complication following Roux-en-Y gastric bypass (RYGB) surgery. The aim of the present study was to examine the progression of MU and identify risk factors for the need for surgical intervention in patients with MU following RYGB. METHODS: A New York state longitudinal administrative database was queried to identify patients who underwent RYGB between 2005 and 2010 and who were followed for at least 4 years for the development of MU using ICD-9 and CPT codes. Patients with perforation as their first presentation of MU were excluded. Multivariable Cox proportional hazard model was built to identify risk factors for surgical intervention. Hazard ratios (HR) with 95% confidence intervals (CI) were reported. RESULTS: We identified 35,075 patients who underwent RYGB. Mean age was 42.47 ± 10.90 years and most were female (81.08%). There were 2201 (6.28%) patients with MU, of which 204 (9.27% of MU; 0.58% of RYGB overall) required surgery. The estimated cumulative incidence of having surgical intervention 1, 2, 5, and 8 years after MU diagnosis was 6% (95% CI 5-7%), 8% (95% CI 7-9%), 13% (95% CI 11-14%), and 17% (95% CI 13-20%), respectively. At time of MU diagnosis, younger age (HR 0.93 every 5 years, 95% CI 0.87-0.99), white race (HR 1.60, 95% CI 1.15-2.23), and weight loss (HR 2.82, 95% CI 1.62-4.88) were independent risk factors for subsequent surgical intervention for MU. Estimated cumulative incidence of MU recurrence was 15% (95% CI 9-22%) and 24% (95 CI% 15-32%) at 6 and 12 months after surgical intervention. CONCLUSIONS: The need for surgical intervention for MU after RYGB is uncommon. Young age, white race, and marked weight loss are risk factors for surgical intervention. Such patients may benefit from early intensive medical therapy at the time of MU diagnosis.

Association between COVID-19 diagnosis and postoperative outcomes in sleeve gastrectomy and Roux-en-Y gastric bypass: A national cohort study.

BACKGROUND: We seek to determine the association between COVID-19 diagnosis and postoperative outcomes following bariatric surgery. METHODS: Using the Metabolic and Bariatric Surgery Accreditation Quality Improvement Project (MBSAQIP) database, patients undergoing sleeve gastrectomy and gastric bypass without a COVID-19 diagnosis were 2:1 propensity-score matched to those with COVID-19 infection pre or postoperatively. RESULTS: 1369 (0.74 â€‹%) and 1331 (0.72 â€‹%) patients had a COVID-19 diagnosis within 14 days prior to or 30 days after their operation, respectively. Patients with preoperative COVID-19 infection had equivalent outcomes to COVID-19 negative patients (all p â€‹> â€‹0.05). Postoperative COVID-19 diagnosis was associated with worse outcomes including increased risk of anastomotic/staple line leak (1.1 â€‹% vs 0.1 â€‹%, p â€‹< â€‹0.001), postoperative pneumonia (2.9 â€‹% vs 0.1 â€‹%, p â€‹< â€‹0.001), and 30-day reoperation (2.1 â€‹% vs 0.9 â€‹%, p â€‹= â€‹0.002). CONCLUSIONS: Postoperative diagnosis of COVID-19 after bariatric surgery is associated with worse outcomes; however, it is safe to perform these procedures on patients recently convalesced from COVID-19 infection.

Fragmented care, Commission on Cancer accreditation, and overall survival in patients receiving surgery and chemotherapy for esophageal cancer.

BACKGROUND: Increasing regionalization for esophagectomy for cancer may lead patients to travel for surgery at one institution and receive chemotherapy at another closer to home. We explore the effects on survival for care fragmentation, the Commission on Cancer status of secondary institutions providing chemotherapy, and the type of institution performing surgery. METHODS: We queried the National Cancer Database to identify all patients who underwent esophagectomy for esophageal cancer and received perioperative chemotherapy between 2006 and 2019. Patients were divided into single-center care, fragmented-to-Commission on Cancer care, or fragmented-to-non-Commission on Cancer care. We identified associations using multivariable logistic regression, Kaplan-Meier survival analyses, and Cox proportional hazards models. RESULTS: A total of 18,502 patients met the criteria for inclusion: 8,290 (44.8%) received single-center care; 3,414 (18.5%) fragmented-to-Commission on Cancer care; and 6,798 (36.4%) fragmented-to-non-Commission on Cancer care. Fragmented care was more likely in White patients (adjusted odds ratio = 1.25; P < .001) and in patients nonadjacent to a metropolitan area (adjusted odds ratio = 1.36; P < .001). Overall survival was equivalent between single-center and fragmented care, but undergoing an esophagectomy at an academic center was associated with improved survival (adjusted hazard ratio = 0.82; P = .016). In patients with an esophagectomy at a nonacademic center, overall survival was best if perioperative chemotherapy was administered at Commission on Cancer-accredited facilities compared with chemotherapy at fragmented-to-non-Commission on Cancer centers (P = .022). CONCLUSION: Most of the esophageal cancer care in the US is fragmented at multiple institutions. When care is fragmented, it is most commonly at non-Commission on Cancer centers for perioperative chemotherapy. Overall survival is best when esophagectomy is performed at an academic center, and perioperative therapy is administered at Commission on Cancer-accredited facilities.

Esophageal cancer: Does inaccuracy in clinical staging affect our ability to reach optimal outcomes?

BACKGROUND: Pretreatment clinical staging is used to decide the course of treatment in early-stage esophageal cancer. Few studies assess the effect of inaccurate clinical staging on oncologic outcomes. METHODS: We queried the National Cancer Database to identify patients undergoing esophagectomy for clinical stage cT1bN0 esophageal carcinoma between 2010 and 2019. Patients were categorized as being upstaged if, on final pathology, they had histopathologic disease that would have warranted treatment with neoadjuvant therapy. The textbook oncologic outcome was defined as margin-negative resection, 15 lymph nodes examined, a hospital stay of <21 days, no unplanned 30-day readmission or mortality, and stage-appropriate use of neoadjuvant therapy. RESULTS: In total, 916 patients met inclusion criteria; 378 (41.2%) had a pathologic stage that differed from their pretreatment clinical stage. By multivariable regression, factors associated upstaging included: presentation between 2015 and 2019 (odds ratio 1.92 95% confidence interval [1.19, 3.13]), delay to esophagectomy of >30 days (odds ratio 2.38 95% confidence interval [1.13, 5.57]), larger tumor size (>2 cm relative to <2 cm, odds ratio 2.73 95% confidence interval [1.72, 4.39]), and poorly differentiated histology (odds ratio 2.79 95% confidence interval [1.75, 4.49]). The rate of textbook oncologic outcome assuming reliable clinical staging was 43.8%; accounting for upstaging, the rate of textbook oncologic outcome was 22.5% (P < .001). CONCLUSION: In patients with cT1bN0 esophageal cancer, tumor size and histology are associated with the risk of inaccurate pretreatment clinical staging. Inaccuracies in clinical staging impact the rate at which providers achieve optimal oncologic outcomes.

Locally advanced pancreatic cancer: Is surgical palliation associated with improved clinical outcome relative to medical palliation?

BACKGROUND: The value of palliative surgery in pancreatic cancer is not well-defined. METHODS: We queried the National Cancer Database for patients undergoing curative-intent resection, palliative surgery or medical palliation for clinical stage cT4N0-2M0 pancreatic cancer. Cohorts were 1:1:1 propensity-score-matched for comorbidities and stage. Kaplan-Meier method was used to compare overall survival for matched cohorts. RESULTS: 9,107 patients met inclusion criteria: 3,567 (39 â€‹%) underwent curative intent surgery, 1608 (18 â€‹%) surgical palliation, 3932 (43 â€‹%) medical palliation. Patients undergoing resection and surgical palliation had significant hospitalizations (11.0 â€‹± â€‹0.4 vs. 10.0 â€‹± â€‹0.3 days; p â€‹= â€‹0.821) and rates of readmission (8.1 â€‹% vs. 2.0 â€‹%; p â€‹< â€‹0.001). Patients undergoing surgical palliation demonstrated marginal increases in survival relative to those undergoing medical palliation (8.54 vs. 7.36 months; p â€‹< â€‹0.0001). CONCLUSION: In patients undergoing care for locally advanced pancreatic cancer, palliative surgery is associated with marginal improvement in survival but significant lengths of hospitalization and risk of readmission.

Fragmented care in localized pancreatic cancer: Is commission on cancer accreditation associated with improved overall survival?

BACKGROUND: Prior studies of fragmentation of care in pancreatic cancer have not adjusted for indicators of hospital quality such as Commission on Cancer accreditation. The effect of fragmentation of care has not been well defined. METHODS: We queried the National Cancer Database to identify patients undergoing pancreaticoduodenectomy and distal pancreatectomy with perioperative systemic therapy for clinical stages I-III pancreatic cancer between 2006 and 2019. Patients who received systemic therapy at a center different than the center performing surgery were categorized as having fragmentation of care. Patients having fragmentation of care were further categorized on the basis of whether (fragmentation of care Commission on Cancer) or not (fragmentation of care non-Commission on Cancer) systemic therapy was administered at a facility accredited by the Commission on Cancer. RESULTS: A total of 11,732 patients met inclusion criteria; 5,668 (48.3%) underwent fragmentation of care, and 3,426 (29.2%) fragmentation of care non-Commission on Cancer. Patients undergoing fragmentation of care non-Commission on Cancer were less likely to receive neoadjuvant systemic therapy than those undergoing fragmentation of care Commission on Cancer or non-fragmented care (27.7% vs 40.1% vs 36.8%, P < .001). On Cox analysis, advanced age, comorbid disease, node-positive disease, and facility type were associated with risk of overall survival. Fragmentation of care was not (adjusted hazard ratio = 0.99, 95% confidence interval [0.94-1.06], P = .8). On Kaplan-Meier analysis, there were no significant differences in 5-year overall survival between treatment cohorts. CONCLUSION: In patients undergoing fragmentation of care for localized pancreatic cancer, those treated with systemic therapy in Commission on Cancer accredited facilities are more likely to be given neoadjuvant therapy but demonstrate no significant improvement in survival relative to those undergoing non-fragmented care or those undergoing fragmentation of care but receiving systemic therapy in nonaccredited facilities.

Locally Advanced Adenocarcinoma of the Esophagus: Is Esophagectomy Associated with Improved Overall Survival?

BACKGROUND: Esophagectomy in locally advanced esophageal adenocarcinoma is challenging and carries risk. The value of esophagectomy in locally advanced esophageal adenocarcinoma is not well-defined. STUDY DESIGN: The National Cancer Database was used to identify patients with cT4 esophageal adenocarcinoma from 2004 to 2020. Multivariable regression was used to identify factors associated with use of esophagectomy. Cox modeling was used to identify factors associated with all-cause mortality. Patients undergoing esophagectomy were 1:1 propensity score-matched to patients treated nonsurgically. Kaplan-Meier analysis was used to compare 5-year overall survival (OS). RESULTS: A total of 3,703 patients met inclusion criteria. Of those, 541 (15%) underwent esophagectomy, and 3,162 (85%) did not. Age 65 years or less (adjusted odds ratio [aOR] 1.69, 95% CI 1.33 to 2.14), White race (aOR 2.98, 95% CI 2.24 to 3.96), treatment in academic centers (aOR 1.64, 95% CI 1.33 to 2.02), private insurance (aOR 1.88, 95% CI 1.50 to 2.36), and tumors less than 6 cm (aOR 1.86, 95% CI 1.44 to 2.40) were associated with use of esophagectomy. Government of lack of insurance (hazard ratio [HR] 1.23, 95% CI 1.12 to 1.35), income <$46,000 (HR 1.11, 95% CI 1.03 to 1.20), treatment in nonacademic centers (HR 1.16, 95% CI 1.07 to 1.25), Charlson-Deyo Comorbidity Index 1 or more (HR 1.22, 95% CI 1.12 to 1.32), and tumors 6 cm or more (HR 1.20, 95% CI 1.09 to 1.32) were associated with risk of all-cause mortality. Esophagectomy (HR 0.50, 95% CI 0.44 to 0.56) and systemic therapy (HR 0.40, 95% CI 0.37 to 0.43) were associated with decreased risk of all-cause mortality. Patients undergoing esophagectomy had higher rates of 5-year OS (27.4% vs 13.2%, p < 0.0001) and longer median OS (24.71 vs 10.09 months, p < 0.0001). Among cT4b patients, those who underwent esophagectomy had higher rates of 5-year OS (24.5% vs 12.3%, p < 0.0001) and longer median OS (25.53 vs 11.01 months, p < 0.0001). CONCLUSIONS: In cT4 esophageal adenocarcinoma, esophagectomy is associated with improved rates of 5-year OS compared with nonsurgical treatment.

Does commission on cancer (CoC) accreditation mitigate the effect of care fragmentation on clinical outcome in localized rectal cancer?

BACKGROUND: Studies of fragmented care (FC) in rectal cancer have not adjusted for indicators of hospital quality and may misrepresent the effects of FC. METHODS: We queried the National Cancer Database to identify patients undergoing care for clinical stage II and III rectal adenocarcinoma between 2006 and 2019. Those undergoing FC were sub-categorized based on whether (FC CoC) or not (FC non-CoC) they received systemic therapy at CoC accredited facilities. RESULTS: 44,339 patients met inclusion criteria; 23,921 (54 â€‹%) underwent FC, 16,929 (71 â€‹%) FC non-CoC. Differences in utilization of neoadjuvant therapy (92.3 â€‹% vs 89.7 â€‹% vs 89.5 â€‹%, p â€‹< â€‹0.01) and 5-year overall survival (76.1 vs 75.5 vs 74.1 %, p â€‹< â€‹0.01) between treatment cohorts were marginal. CONCLUSION: In patients undergoing multimodality therapy for rectal cancer, care fragmentation is not associated with long-term clinical outcome. Decisions regarding where these patients go for systemic therapy may be safely made on the basis of ease of access.

Clinical stage T2N0M0 rectal adenocarcinoma: Is radical resection associated with improved overall survival in patients with low-risk histology?

BACKGROUND: Prior studies evaluating the efficacy of local excision compared to radical resection in the treatment of rectal adenocarcinoma lacked sufficient power to identify differences in outcomes for patients with cT2 disease but low-risk histopathology. We compared the outcomes of local excision and radical resection for low-risk histopathology and high-risk histology of patients with cT2N0M0 rectal adenocarcinoma to assess their outcomes. METHODS: We queried the National Cancer Database for patients presenting with cT2N0M0 rectal adenocarcinoma between 2004 and 2019 and categorized them as low-risk histopathology or high-risk histology. We used the Cox proportional hazards model to identify factors associated with the risk of all-cause mortality. We 1:1 propensity-matched patients who underwent local excision to patients who underwent radical resection and used the Kaplan-Meier method to compare overall survival for matched cohorts. RESULTS: Of the 4,446 patients selected, we classified 1,206 (27%) as high-risk histology and 3,240 (73%) as low-risk histopathology. Among the patients with high-risk histology, 121 (10%) underwent local excision and 1,085 (90%) underwent radical resection. Among the patients with low-risk histopathology, 340 (10%) underwent local excision and 2,900 (90%) radical resections. Whereas radical resection was associated with decreased risk of all-cause mortality and increased overall survival for patients with high-risk histology, it was not for patients with low-risk histopathology. CONCLUSION: The overall survival of patients with low-risk histopathology with cT2N0M0 rectal adenocarcinoma who undergo local excision is similar to those of patients with low-risk histopathology who undergo radical resection, suggesting local excision is a reasonable approach for these patients. In contrast, radical resection provides a significant survival advantage for patients with high-risk histology and should remain their treatment of choice.

Laparoscopic and robotic paraesophageal hernia repair in United States veterans: Clinical outcomes and risk factors associated with reoperation recurrence.

BACKGROUND: Despite surgical advances, rates of paraesophageal hernia recurrence remain high. We evaluate outcomes of paraesophageal hernia repair in United States veterans, safety of robotic technology, and risk factors for reoperation for recurrence. METHODS: The Veterans Affairs Surgical Quality Improvement Program database was queried for patients undergoing laparoscopic or robotic paraesophageal hernia repair from 2010 to 2021. The effect of patient and operative characteristics on outcomes was evaluated. RESULTS: 2,444 patients underwent paraesophageal hernia repair. 62 (2.5%) had a reoperation for recurrence. Emergent priority (aOR 18.3 [5.9-56.2]) and younger age (aOR 0.7 [0.5-0.9]) were associated with increased risk of reoperation. On comparison of propensity matched cohorts, repairs done robotically took longer (4.17 vs. 3.57 h, p < 0.001) but had 30-day outcomes and rates of reoperation for recurrence equivalent to laparoscopic repairs (p > 0.05). CONCLUSION: Emergent priority and younger age are associated with increased risk of reoperation for recurrent paraesophageal hernia. Robotic approaches take longer but are safe.

A matched cohort comparison of endoscopic resection, chemoradiation and esophagectomy in the treatment of early-stage esophageal squamous cell carcinoma.

BACKGROUND: The efficacy of endoscopic resection in early-stage esophageal squamous cell carcinoma has not been defined. METHODS: We queried the National Cancer Database to identify patients presenting with cT1N0M0 esophageal squamous cell cancer between 2004 and 2017. Transitive match methods were used to 1:1:1 propensity match patients undergoing endoscopic resection to patients undergoing esophagectomy and those undergoing definitive chemoradiotherapy. Kaplan Meier method was used to compare 5-year overall survival profiles for matched cohorts. RESULTS: 301 patients (19%) underwent endoscopic resection; 497 (32%) esophagectomy; 767 (49%) chemoradiation. On comparison of matched cohorts, patients undergoing chemoradiation demonstrated lower rates of survival than those undergoing esophagectomy (32% vs. 59%, p < 0.0001) while those undergoing endoscopic resection demonstrated rates comparable to patients undergoing esophagectomy (53% vs. 59%, p = 0.77). CONCLUSIONS: For cT1N0M0 esophageal squamous cell cancer, endoscopic resection is associated with rates of survival similar to those following esophagectomy and better than those following definitive chemoradiation.

The role of endoscopic resection in early-stage esophageal adenocarcinoma: Esophagectomy is associated with improved survival in patients presenting with clinical stage T1bN0 disease.

BACKGROUND: Studies evaluating endoscopic resection for early-stage (cT1N0M0) esophageal adenocarcinoma include small numbers of patients with T1b tumors. The role of endoscopic resection in esophageal adenocarcinoma remains incompletely defined. METHODS: We queried the National Cancer Database to identify patients presenting with esophageal adenocarcinoma between 2010 and 2017. Those treated with neoadjuvant chemoradiotherapy and endoscopic ablation were excluded. Patients undergoing endoscopic resection for cT1a and cT1b tumors were separately 1:1 propensity matched for relevant demographic and tumor factors to those undergoing esophagectomy for disease of like clinical stage. The Kaplan-Meier method was used to compare 5-year overall survival for matched cohorts. RESULTS: A total of 3,157 patients met the inclusion criteria. Of these patients, 2,024 (64.1%) had cT1a and 1133 (35.9%) had cT1b disease. Among those with cT1a tumors, 461 (22.8%) underwent esophagectomy, 1,357 (67.0%) endoscopic resection, and 206 (10.2%) treatment with chemoradiotherapy alone. Among those with cT1b tumors, 649 (57.3%) underwent esophagectomy, 293 (25.9%) endoscopic resection, and 191 (16.8%) chemoradiotherapy. On unadjusted comparison, patients treated for esophageal adenocarcinoma with chemoradiotherapy had a lower rate of overall survival than those treated with endoscopic resection or esophagectomy (26.1% vs 73.1% vs 75.5%, P < .001). On comparison of matched cohorts, patients undergoing endoscopic resection for cT1b tumors demonstrated lower rates of overall survival than those undergoing esophagectomy (60.6% vs 74.1%, P = .0013), whereas those undergoing endoscopic resection for cT1a tumors demonstrated rates of overall survival statistically similar to those undergoing esophagectomy (77.8% vs 80.2%, P = .75). CONCLUSION: Esophagectomy is associated with improved overall survival relative to endoscopic resection in patients presenting with cT1bN0M0 but not in those with cT1a esophageal adenocarcinoma.

Association of Resident Independence With Short-term Clinical Outcome in Core General Surgery Procedures.

Importance: Prior studies evaluating the effect of resident independence on operative outcome draw from case mixes that cross disciplines and overrepresent cases with low complexity. The association between resident independence and clinical outcome in core general surgical procedures is not well defined. Objective: To evaluate the level of autonomy provided to residents during their training, trends in resident independence over time, and the association between resident independence in the operating room and clinical outcome. Design, Setting, and Participants: Using the Veterans Affairs Surgical Quality Improvement Program database from 2005 to 2021, outcomes in resident autonomy were compared using multivariable logistic regression and propensity score matching. Data on patients undergoing appendectomy, cholecystectomy, partial colectomy, inguinal hernia, and small-bowel resection in a procedure with a resident physician involved were included. Exposures: Resident independence was graded as the attending surgeon scrubbed into the operation (AS) or the attending surgeon did not scrub (ANS). Main Outcomes and Measures: Outcomes of interest included rates of postoperative complication, severity of complications, and death. Results: Of 109 707 patients who met inclusion criteria, 11 181 (10%) underwent operations completed with ANS (mean [SD] age of patients, 61 [14] years; 10 527 [94%] male) and 98 526 (90%) operations completed with AS (mean [SD] age of patients, 63 [13] years; 93 081 [94%] male). Appendectomy (1112 [17%]), cholecystectomy (3185 [11%]), and inguinal hernia (5412 [13%]) were more often performed with ANS than small-bowel resection (527 [6%]) and colectomy (945 [4%]). On multivariable logistic regression adjusting for procedure type, age, body mass index, functional status, comorbidities, American Society of Anesthesiologists class, wound class, case priority, admission status, facility type, and year, factors associated with a complication included increasing age (adjusted odds ratio [aOR], 1.19 [95% CI, 1.16-1.22]), emergent case priority (aOR, 1.41 [95% CI, 1.33-1.50]), and resident independence (aOR, 1.12 [95% CI, 1.03-1.22]). On propensity score matching, AS cases were score matched 1:1 to ANS cases based on the variables listed above. Comparing matched cohorts, there was no difference in complication rates (817 [7%] vs 784 [7%]) or death (91 [1%] vs 102 [1%]) based on attending physician involvement. Conclusions and Relevance: Core general surgery cases performed by senior-level trainees in such a way that the attending physician is not scrubbed into the case are being done safely with no significant difference in rates of postoperative complication.

Early-Stage Ampullary Cancer: Is Local Excision an Effective Alternative to Radical Resection?

BACKGROUND: The efficacy of local excision (transduodenal or endoscopic ampullectomy) in treating early-stage ampullary cancer has not been well defined. STUDY DESIGN: We queried the National Cancer Database to identify patients undergoing either local tumor excision or radical resection for early-stage (cTis-T2, N0, M0) ampullary adenocarcinoma between 2004 and 2018. Cox modeling was used to identify factors associated with overall survival. Patients undergoing local excision were then 1:1 propensity score-matched for demographics, hospital level, and histopathological factors to those undergoing radical resection. The Kaplan-Meier method was used to compare overall survival (OS) profiles for matched cohorts. RESULTS: A total of 1,544 patients met inclusion criteria. A total of 218 (14%) underwent local tumor excision, and 1,326 (86%) radical resection. On propensity score matching, 218 patients undergoing local excision were successfully matched to 218 patients undergoing radical resection. On comparison of matched cohorts, those undergoing local excision had lower rate of margin-negative (R0) resection (85.1% vs 99%, p < 0.001) and lower median lymph node count (0 vs 13, p < 0.001) but had significantly shorter length of initial hospitalization (median days: 1 vs 10 days, p < 0.001), lower rate of 30-day readmission (3.3% vs 12.0%, p = 0.001), and lower rate of 30-day mortality (1.8% vs 6.5%, p = 0.016) than patients undergoing radical resection. There was no statistically significant difference in OS between the matched cohorts (46.9% vs 52.0%, p = 0.46). CONCLUSIONS: In patients presenting with early-stage ampullary adenocarcinoma, local tumor excision is associated with higher rate of R1 resection but accelerated postprocedure recovery and patterns of OS comparable with those after radical resection.

Rectal neuroendocrine tumors: Can they be observed?

BACKGROUND: Studies comparing approaches to managing rectal neuroendocrine tumors are underpowered by institutional series. The efficacy of expectant management relative to local excision and radical resection is poorly defined. METHODS: We queried the National Cancer Database to identify patients presenting with non-metastatic rectal neuroendocrine tumors between 2004 and 2019. Multivariable regression was used to identify factors associated with expectant management. Cox modeling was used to identify factors associated with all-cause mortality. Patients undergoing expectant management were 1:1:1 propensity score matched for demographics and comorbid disease to those undergoing radical resection and local excision. The Kaplan-Meier method was used to compare overall survival profiles for matched cohorts. RESULTS: A total of 6,316 patients met the inclusion criteria. Of these, 5,211 (83%) underwent local excision, 600 (9.5%) radical resection, and 505 (8%) expectant management. On multivariable regression, factors associated with expectant management included Black race, government insurance, and tumor size <2.0 centimeters. On Cox modeling, factors associated with mortality included age >65 years, male sex, government insurance, comorbidity score >0, tumor size >2 centimeters, and poorly differentiated histology. On comparison of matched cohorts: patients undergoing radical resection had longer hospitalizations and higher readmission rates than those undergoing local excision; there was no difference in overall survival between cohorts in patients with stage 1 disease; in stage 2 and 3 diseases, patients undergoing local excision and radical resection demonstrated improved rates of overall survival relative to those undergoing expectant management. CONCLUSION: Expectant management is a reasonable approach for patients with stage 1 rectal neuroendocrine tumors. Local excision should be the preferred treatment option for those presenting with stage 2/3 disease.

Is local excision an appropriate treatment modality in patients presenting with early-stage (cT1 N0 M0) rectal adenocarcinoma?

BACKGROUND: Prior studies evaluating the safety and efficacy of local excision relative to surgical resection in early-stage rectal adenocarcinoma have primarily included low rectal cancers treated with abdominoperineal resection as control comparison cohorts. The role of local excision in early-stage rectal adenocarcinoma is incompletely defined. METHODS: We queried the National Cancer Database to identify patients with cT1 N0 M0 rectal adenocarcinoma between 2004 and 2019. Patients undergoing abdominoperineal resection were excluded. Multivariable regression was used to identify factors associated with use of local excision instead of low anterior resection. Patients undergoing local excision were propensity score matched for age, sex, demographic characteristics, Charlson-Deyo comorbidity class score, and tumor grade and size to those undergoing low anterior resection. Short-term clinical outcomes and 5-year overall survival for matched cohorts were compared by standard methods. RESULTS: A total of 5,693 patients met inclusion criteria; 1,973 patients underwent local excision and 3,720 low anterior resection. Age (adjusted odds ratio 1.26; 95% confidence interval, 1.17-1.37), tumor histology (poorly differentiated histology: adjusted odds ratio 0.66; 95% confidence interval, 0.51-0.86), and size (>4 cm: adjusted odds ratio 0.20; 95% confidence interval, 0.16-0.25) were associated with choice of intervention. On comparison of matched cohorts, patients undergoing LE demonstrated shorter hospital stay (2.4 ±9.8 vs 5.6 ±8.1 days; P < .001) and lower readmission rate (4% vs 7%; P = .002) but higher margin-positive resection rates (8% vs 2%; P < .001). Overall survival profiles for patients undergoing local excision were comparable with those for low anterior resection. CONCLUSION: In patients with cT1 N0 M0 rectal adenocarcinoma, local excision is associated with a higher margin-positive resection rate than low anterior resection but affords accelerated postprocedure recovery and comparable rates of overall survival.

Are Residents Able to Perform a Laparoscopic Cholecystectomy with Acceptable Outcomes When the Attending Is Not Scrubbed?

BACKGROUND: Recent socioeconomic pressures in healthcare and work hour resections have limited opportunities for resident autonomy and independent decision-making. We sought to evaluate whether contemporary senior residents are being given the opportunity to operate independently and whether patient outcomes are affected when the attending is not directly involved in an operation. STUDY DESIGN: The VA Surgical Quality Improvement Program (VASQIP) Database was queried to identify patients undergoing elective laparoscopic cholecystectomy between 2004 and 2019. Cases were categorized as "attending" or "resident" depending on whether the attending surgeon was scrubbed. Cohorts were 1:1 propensity score-matched (PSM) for demographics, comorbidities, and facility case-mix. Clinical outcomes for matched cohorts were compared by standard methods. RESULTS: There were 23,831 records for patients who underwent laparoscopic cholecystectomy; 20,568 (86%) performed with the attending scrubbed, and 3,263 (14%) without the attending scrubbed. Over time there was a significant decrease in the proportion of cases without the attending scrubbed, 18% in 2004-2009 to 13% in 2015-2019 (p < 0.001). On PSM, 3,263 patients undergoing laparoscopic cholecystectomy by the residents without the attending scrubbed were successfully matched (1:1) to cases with the attending scrubbed. On comparison of matched cohorts, procedures performed without the attending scrubbed were statistically longer (102 vs 98 minutes, p = 0.001) but with no difference in rates of postoperative complications (5% vs 5%, p = 0.9). CONCLUSION: In comparison with cases done with more direct attending involvement, residents perform laparoscopic cholecystectomies efficiently without increased complications. Over time, attendings are more frequently scrubbed for the operation.

Contemporary Matched-Cohort Comparison of Surgical Approach to Inguinal Hernia Repair: Are Minimally Invasive Approaches Associated with Higher Rates of Recurrence?

BACKGROUND: Current studies evaluating outcomes for open, laparoscopic, and robotic inguinal hernia repair, in general, include small numbers of robotic cases and are not powered to allow a direct comparison of the 3 approaches to repair. STUDY DESIGN: We queried the Veterans Affairs Surgical Quality Improvement Program Database to identify patients undergoing initial elective inguinal hernia repair between 2013 and 2017. Propensity score matching and multivariable logistic regression were used to make risk-adjusted assessments of association between surgical approach and outcome. RESULTS: A total of 39,358 patients underwent initial elective inguinal hernia repair; 32,881 (84%) underwent an open approach, 6,135 (16%) underwent a laparoscopic approach, and 342 (1%) underwent a robotic-assisted approach. Two hundred sixty-six (1%) patients had a recurrent repair performed during follow-up. On univariate comparison, patients undergoing a robotic-assisted approach had longer operative times for unilateral repair than those undergoing either an open or laparoscopic (73 ± 31 vs 74 ± 29 vs 107 ± 41 minutes; p < 0.001) approach. On multivariable logistic regression, patients with a higher BMI had an increased adjusted risk of a postoperative complication, but there was no association between surgical approach and complication rate. Three hundred forty-two patients undergoing robotic repair were 1:3:3 propensity score matched to 1,026 patients undergoing laparoscopic and 1,026 undergoing open repair. On comparison of matched cohorts, there were no statistical differences between approaches regarding recurrence (0.6% vs 0.8% vs 0.6%, p > 0.05) or complication rate (0.6% vs 1.2% vs 1.2%, p > 0.05). CONCLUSIONS: In patients undergoing initial elective inguinal hernia repair, rates of hernia recurrence are low independent of surgical approach. Both robotic and laparoscopic approaches demonstrate rates of early postoperative morbidity and recurrence similar to those for the open approach. The robotic approach is associated with longer operative time than either laparoscopic or open repair.

Supervised independence in elective inguinal hernia repairs performed by surgical residents is not associated with compromised short clinical outcome or rates of reoperation for recurrence.

BACKGROUND: We evaluate the association between attending surgeon involvement and clinical outcome in elective inguinal hernia repairs performed by residents. METHODS: Patients undergoing initial elective unilateral inguinal hernia repair between 2004 and 2019 were identified using the Veterans Administration Surgical Quality Improvement Program Database. The level of attending surgeon involvement was categorized as active (attending scrubbed [AS]) or passive (supervising the resident's performance but not scrubbed [ANS]). AS and ANS herniorrhaphies were 1:1 propensity matched for patient demographics, comorbidities, surgical approach, resident postgraduate level, and year of repair. Rates of complication and recurrence for matched cohorts were compared by standard methods. RESULTS: 30,784 patients met inclusion criteria. 5136 (17%) repairs were performed without the attending scrubbed. On comparison of matched-cohorts, overall complication rates (1.7% vs 1.2%, p = 0.07) and rates of recurrence (1.9% vs 1.4%, p = 0.041) for patients undergoing herniorrhaphy AS were statistically similar to those performed ANS. CONCLUSION: Supervised independence in elective inguinal hernia repair performed by surgical residents is not associated with inferior clinical outcomes.
