Primary hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM) represent the two most common malignant neoplasms of the liver. The objective of this study was to assess outcomes of surgical approaches to liver ablation comparing laparoscopic versus percutaneous microwave ablation (MWA), and MWA versus radiofrequency ablation (RFA) in patients with HCC or CRLM lesions smaller than 5 cm.A systematic review was conducted across seven databases, including PubMed, Embase, and Cochrane, to identify all comparative studies between 1937 and 2021. Two independent reviewers screened for eligibility, extracted data for selected studies, and assessed study bias using the modified Newcastle Ottawa Scale. Random effects meta-analyses were subsequently performed on all available comparative data.From 1066 records screened, 11 studies were deemed relevant to the study and warranted inclusion. Eight of the 11 studies were at high or uncertain risk for bias. Our meta-analyses of two studies revealed that laparoscopic MW ablation had significantly higher complication rates compared to a percutaneous approach (risk ratio = 4.66; 95% confidence interval = [1.23, 17.22]), but otherwise similar incomplete ablation rates, local recurrence, and oncologic outcomes. The remaining nine studies demonstrated similar efficacy of MWA and RFA, as measured by incomplete ablation, complication rates, local/regional recurrence, and oncologic outcomes, for both HCC and CRLM lesions less than 5 cm (p 0.05 for all outcomes). There was no statistical subgroup interaction in the analysis of tumors 3 cm.The available comparative evidence regarding both laparoscopic versus percutaneous MWA and MWA versus RFA is limited, evident by the few studies that suffer from high/uncertain risk of bias. Additional high-quality randomized trials or statistically matched cohort studies with sufficient granularity of patient variables, institutional experience, and physician specialty/training will be useful in informing clinical decision making for the ablative treatment of HCC or CRLM.

Weight loss surgery has overall been shown to be very safe and effective. However, long-term outcomes data has allowed codification of post-operative complications specific to the type of weight loss surgery performed. This review focuses specifically on foregut-related postoperative complications after weight loss surgery, most of which are not discussed on a broad scale in the literature yet whose prevalence continues to rise. Clinicians should maintain a broad differential when treating patients with complications after bariatric surgery in order to perform a thorough and precise workup to identify the diagnosis and guide management.

SAGES partners with the Fellowship Council (FC) to offer fellowships in MIS and flexible endoscopy. The FC has a robust accreditation process for fellowship programs; however, the FC is not able to address certification of individual graduates. This situation is similar to the structure of residencies whereby the ACGME accredits programs but individual board certification is delegated to constituent boards of the American Board of Medical Specialties (ABMS). In light of this gap, sponsoring societies have developed programs for issuing certificates to graduates of fellowship programs who have met predetermined standards. The purpose of this paper is to describe the SAGES Certificate Process for Adv GI MIS and Flexible Endoscopy Fellowships. The SAGES Certificate program was developed through a rigorous process and has undergone recent revision to modernize the certificate criteria. Research has shown that as many as 80% of general surgery graduates go on to complete additional fellowship training. Given the number of graduates who complete this subspecialty training each year, general surgery board certification may not be an appropriate final benchmark. The SAGES certificate program joins a long list of certification pathways for surgical fellowship trainees in ACGME and non-ACGME programs. In the future, SAGES plans to assess competency in all of core content domains with validated assessments.

Background Obesity is a widely accepted risk factor for the development of severe COVID-19. We sought to determine the survival benefit of early initiation of aggressive anticoagulation in obese critically ill COVID-19 patients. Methods We retrospectively reviewed 237 intubated patients at a single academic accredited bariatric center and stratified them based on their BMI into 2 groups, obese (BMI > 30) and non-obese (BMI ≤ 30). We used chi-square tests to compare categorical variables such as age and sex, and two-sample t-tests or Mann Whitney U-tests for continuous variables, including important laboratory values. Cox proportional-hazards regression models were utilized to determine whether obesity was an independent predictor of survival and multivariable analysis was performed to compare risk factors that were deemed significant in the univariable analysis. Survival with respect to BMI and its association with level of anticoagulation in the obese cohort was evaluated using Kaplan–Meier models. Results The overall mortality in the obese and non-obese groups was similar at 47% and 44%, respectively (p = 0.65). Further analysis based on the level of AC showed that obese patients placed on early aggressive AC protocol had improved survival compared to obese patients who did not receive protocol based aggressive AC (ON-aggressive AC protocol 26% versus OFF-aggressive AC protocol 61%, p = 0.0004). Conclusions The implementation of early aggressive anticoagulation may balance the negative effects of obesity on the overall mortality in critically ill COVID-19 patients. Graphical abstract

Background Minimally invasive splenectomy (MIS) is increasingly favored for the treatment of benign and malignant diseases of the spleen over open access approaches. While many studies cite the superiority of MIS in terms of decreased morbidity and length of stay over a traditional open approach, the comparative effectiveness of specific technical and peri-operative approaches to MIS is unclear. Objective To develop evidence-based guidelines that support clinicians, patients, and others in decisions on the peri-operative performance of MIS. Methods A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) including methodologists used the Grading of Recommendations Assessment, Development and Evaluation approach to grade the certainty of evidence and formulate recommendations. Results Informed by a systematic review of the evidence, the panel agreed on eight recommendations for the peri-operative performance of MIS for adults and children in elective situations addressing six key questions. Conclusions Conditional recommendations were made in favor of lateral positioning for non-hematologic disease, intra-operative platelet administration for patients with idiopathic thrombocytopenic purpura instead of preoperative administration, and the use of mechanical devices to control the splenic hilum. Further, a conditional recommendation was made against routine intra-operative drain placement.

BACKGROUND Gender disparities in surgical leadership have come under increased scrutiny, and in order to better understand why these disparities exist, it is important to study the disparities across surgical fellowship programs. METHODS Data derived from the Fellowship Council (FC) database for fellows completing training from academic years 2015-2019 were analyzed. Available information included institution, fellowship type, program director (PD), associate program director (APD), faculty, and fellow names for all FC Fellowships. Faculty and fellow gender were determined from personal knowledge or publicly available online biographical information. RESULTS A total of 1023 fellows and 221 programs were analyzed. The advanced gastrointestinal (GI)/minimally invasive surgery (MIS) fellowship programs included 321 fellows, with a small increase in the percentage of female fellows from 28 to 31% over 5 years. Advanced GI/MIS/bariatric fellowship programs had a total of 262 fellows, also with a small increase in the percent of female fellows, from 29 to 38% in the study period. The gender of program directors, assistant program directors, and faculty for the fellowship programs studied were analyzed as well. Of the 221 programs in the Fellowship Council data, 13.6% of program directors, 18.3% of associate program directors, and 19.9% of faculty were female. Advanced GI/MIS fellowship programs had the lowest percentage of female PDs, with only 9.3% of the program directors being female. Colorectal surgery fellowships had the highest percentage of female PDs, with 33% being female. CONCLUSIONS In conclusion, women are underrepresented in gastrointestinal surgery fellowships among both trainees and educators. It is likely that a significant contributing factor to this underrepresentation of female fellows is the underrepresentation of female program directors and faculty; although neither our study nor any previously published study has proven that statistically.

Gastroesophageal Reflux Disease (GERD) is an extremely common condition with several medical and surgical treatment options. A multidisciplinary expert panel was convened to develop evidence-based recommendations to support clinicians, patients, and others in decisions regarding the treatment of GERD with an emphasis on evaluating different surgical techniques. Literature reviews were conducted for 4 key questions regarding the surgical treatment of GERD in both adults and children: surgical vs. medical treatment, robotic vs. laparoscopic fundoplication, partial vs. complete fundoplication, and division vs. preservation of short gastric vessels in adults or maximal versus minimal dissection in pediatric patients. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed. The panel provided seven recommendations for adults and children with GERD. All recommendations were conditional due to very low, low, or moderate certainty of evidence. The panel conditionally recommended surgical treatment over medical management for adults with chronic or chronic refractory GERD. There was insufficient evidence for the panel to make a recommendation regarding surgical versus medical treatment in children. The panel suggested that once the decision to pursue surgical therapy is made, adults and children with GERD may be treated with either a robotic or a laparoscopic approach, and either partial or complete fundoplication based on surgeon–patient shared decision-making and patient values. In adults, the panel suggested either division or non-division of the short gastric vessels is appropriate, and that children should undergo minimal dissection during fundoplication. These recommendations should provide guidance with regard to surgical decision-making in the treatment of GERD and highlight the importance of shared decision-making and patient values to optimize patient outcomes. Pursuing the identified research needs may improve future versions of guidelines for the treatment of GERD.

Objective: The aim of this work is to formulate recommendations based on global expert consensus to guide the surgical community on the safe resumption of surgical and endoscopic activities. Background: The COVID-19 pandemic has caused marked disruptions in the delivery of surgical care worldwide. A thoughtful, structured approach to resuming surgical services is necessary as the impact of COVID-19 becomes better controlled. The Coronavirus Global Surgical Collaborative sought to formulate, through rigorous scientific methodology, consensus-based recommendations in collaboration with a multidisciplinary group of international experts and policymakers. Methods: Recommendations were developed following a Delphi process. Domain topics were formulated and subsequently subdivided into questions pertinent to different aspects of surgical care in the COVID-19 crisis. Forty-four experts from 15 countries across 4 continents drafted statements based on the specific questions. Anonymous Delphi voting on the statements was performed in 2 rounds, as well as in a telepresence meeting. Results: One hundred statements were formulated across 10 domains. The statements addressed terminology, impact on procedural services, patient/staff safety, managing a backlog of surgeries, methods to restart and sustain surgical services, education, and research. Eighty-three of the statements were approved during the first round of Delphi voting, and 11 during the second round. A final telepresence meeting and discussion yielded acceptance of 5 other statements. Conclusions: The Delphi process resulted in 99 recommendations. These consensus statements provide expert guidance, based on scientific methodology, for the safe resumption of surgical activities during the COVID-19 pandemic.

This study aimed to examine socioeconomic disparities in the utilization of primary robotic hernia repair (RHR), utilizing statewide population-level data. It was funded by the SAGES Robotic Surgery Research Grant.The New York Statewide Planning and Research Cooperative System (SPARCS) administrative database was used to identify adult patients who underwent primary open, laparoscopic, and robotic hernia repair (inguinal, femoral, umbilical, ventral) from 2010 through 2016. Utilization trends were compared between the surgical approaches, assessing for difference in age, sex, race, insurance status, and socioeconomic status (as defined by median income for zip code). Multivariable regression models were used with statistical significance set at 0.05.A total of 280,064 patients underwent primary hernia repair: n = 216,892 (77.4%) open, n = 61,037 (21.8%) laparoscopic, and n = 2,135 (0.8%) robotic. After adjusting for confounding variables, senior age (OR 1.01, p = 0.002), male sex (OR 1.35, p 0.001), and non-Hispanic race (OR 1.3-1.54, p 0.001) were significantly associated with the use of robotic compared to open or laparoscopic surgery. Additionally, patients with commercial insurance were more likely to undergo RHR compared to those with Medicare (OR 1.32) or Medicaid (OR 1.54) (p 0.0001). Income was significantly correlated with RHR such that every $10,000 increase in income would increase the odds of having RHR by 6% (OR 1.06, p 0.0001). Academic facilities were also associated with a significantly higher likelihood of utilizing RHR (OR 1.88, p 0.0001).There are significant socioeconomic disparities in the utilization of robotic compared to laparoscopic or open hernia repair. While the robotic approach is overall increasing in popularity, adoption of new technology should not be limited to specific socioeconomic cohorts of the population. Recognizing these disparities is a necessary first step in providing equal and consistent care.

The mission of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) is to innovate, educate, and collaborate to improve patient care. A critical element in meeting this mission is the publishing of trustworthy and current guidelines for the practicing surgeon. In this manuscript, we outline the steps of developing high quality practice guidelines using a completely volunteer-based professional organization. SAGES has developed a standardized approach to train volunteer surgeons and trainees alike to develop clinically pertinent guidelines in a timely manner, without sacrificing quality. This methodology can be used more widely by volunteer organizations to efficiently develop effective tools for practicing physicians.

Background Although acute gastrointestinal injury (AGI) and feeding intolerance (FI) are known independent determinants of worse outcomes and high mortality in intensive care unit (ICU) patients, the incidence of AGI and FI in critically ill COVID-19 patients and their prognostic importance have not been thoroughly studied. Methods We reviewed 218 intubated patients at Stony Brook University Hospital and stratified them into three groups based on AGI severity, according to data collected in the first 10 days of ICU course. We used chi-square test to compare categorical variables such as age and sex and two-sample t-test or Mann-Whitney U-tests for continuous variables, including important laboratory values. Cox proportional hazards regression models were utilized to determine whether AGI score was an independent predictor of survival, and multivariable analysis was performed to compare risk factors that were deemed significant in the univariable analysis. We performed Kaplan-Meier survival analysis based on the AGI score and the presence of FI. Results The overall incidence of AGI was 95% (45% AGI I/II, 50% AGI III/IV), and FI incidence was 63%. Patients with AGI III/IV were more likely to have prolonged mechanical ventilation (22 days vs 16 days, P-value

Achalasia is a debilitating primary esophageal motility disorder. Heller myotomy (HM) is a first-line therapy for the treatment of achalasia patients who have failed other modalities. Other indications for HM include diverticulum, diffuse esophageal spasm, and esophageal strictures. However, long-term outcomes of HM are unclear. This study aims to assess incidence of reintervention, either endoscopically or through minimally invasive or resectional procedures, in patients who underwent HM in New York State. The Statewide Planning and Research Cooperative System (SPARCS) administrative longitudinal database identified 1817 adult patients who underwent HM between 2000 and 2008 for achalasia, esophageal diverticulum, diffuse esophageal spasm, and esophageal strictures, based on ICD-9 and CPT codes. Through the use of unique identifiers, patients requiring reintervention were tracked up to 2016 (for at least 8 years follow-up). Primary outcome was incidence of subsequent procedures following HM. Secondary outcomes were time to reintervention and risk factors for reintervention. Of the 1817 patients who underwent HM, 320 (17.6%) required subsequent intervention. Of the 320 patients, 234 (73.1%) underwent endoscopic reinterventions, 54 (16.9%) underwent minimally invasive procedures, and 32 (10%) underwent resectional procedures as their initial revisional intervention. Of the 234 patients who underwent endoscopic reintervention as their initial revisional procedure, only 40 (16.8%) required subsequent surgical procedures. Over a mean follow-up of 7.0 years, the mean time to a subsequent procedure was 4.3 ± 3.74 years. Reintervention rates after 10 years following HM for achalasia, diverticulum ,and other indication were 24.4%, 12.6%, and 37%, respectively. The majority of HM reinterventions were managed solely by endoscopic procedures (60.6%). Heller myotomy remains an excellent procedure to prevent surgical reintervention for achalasia and diverticulum.

Achalasia is a rare, chronic, and morbid condition with evolving treatment. Peroral endoscopic myotomy (POEM) has gained considerable popularity, but its comparative effectiveness is uncertain. We aim to evaluate the literature comparing POEM to Heller myotomy (HM) and pneumatic dilation (PD) for the treatment of achalasia. We conducted a systematic review of comparative studies between POEM and HM or PD. A priori outcomes pertained to efficacy, perioperative metrics, and safety. Internal validity of observational studies and randomized trials (RCTs) was judged using the Newcastle Ottawa Scale and the Cochrane Risk of Bias 2.0 tool, respectively. From 1379 unique literature citations, we included 28 studies comparing POEM and HM (n = 21) or PD (n = 8), with only 1 RCT addressing each. Aside from two 4-year observational studies, POEM follow-up averaged ≤ 2 years. While POEM had similar efficacy to HM, POEM treated dysphagia better than PD both in an RCT (treatment “success” RR 1.71, 95% CI 1.34–2.17; 126 patients) and in observational studies (Eckardt score MD − 0.43, 95% CI − 0.71 to − 0.16; 5 studies; I2 21%; 405 patients). POEM needed reintervention less than PD in an RCT (RR 0.19, 95% CI 0.08–0.47; 126 patients) and HM in an observational study (RR 0.33, 95% CI 0.16, 0.68; 98 patients). Though 6–12 months patient-reported reflux was worse than PD in 3 observational studies (RR 2.67, 95% CI 1.02–7.00; I2 0%; 164 patients), post-intervention reflux was inconsistently measured and not statistically different in measures ≥ 1 year. POEM had similar safety outcomes to both HM and PD, including treatment-related serious adverse events. POEM has similar outcomes to HM and greater efficacy than PD. Reflux remains a critical outcome with unknown long-term clinical significance due to insufficient data and inconsistent reporting.

Gastroesophageal reflux disease (GERD) has a high worldwide prevalence in adults and children. There is uncertainty regarding medical versus surgical therapy and different surgical techniques. This review assessed outcomes of antireflux surgery versus medical management of GERD in adults and children, robotic versus laparoscopic fundoplication, complete versus partial fundoplication, and minimal versus maximal dissection in pediatric patients. PubMed, Embase, and Cochrane databases were searched (2004–2019) to identify randomized control and non-randomized comparative studies. Two independent reviewers screened for eligibility. Random effects meta-analysis was performed on comparative data. Study quality was assessed using the Cochrane Risk of Bias and Newcastle Ottawa Scale. From 1473 records, 105 studies were included. Most had high or uncertain risk of bias. Analysis demonstrated that anti-reflux surgery was associated with superior short-term quality of life compared to PPI (Std mean difference = − 0.51, 95%CI − 0.63, − 0.40, I2 = 0%) however short-term symptom control was not significantly superior (RR = 0.75, 95%CI 0.47, 1.21, I2 = 82%). A proportion of patients undergoing operative treatment continue PPI treatment (28%). Robotic and laparoscopic fundoplication outcomes were similar. Compared to total fundoplication, partial fundoplication was associated with higher rates of prolonged PPI usage (RR = 2.06, 95%CI 1.08, 3.94, I2 = 45%). There was no statistically significant difference for long-term symptom control (RR = 0.94, 95%CI 0.85, 1.04, I2 = 53%) or long-term dysphagia (RR = 0.73, 95%CI 0.52, 1.02, I2 = 0%). Ien, minimal dissection during fundoplication was associated with lower reoperation rates than maximal dissection (RR = 0.21, 95%CI 0.06, 0.67). The available evidence regarding the optimal treatment of GERD often suffers from high risk of bias. Additional high-quality randomized control trials may further inform surgical decision making in the treatment of GERD.

The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Guidelines Committee develops evidence-based guidelines for practicing surgeons using standard methodology. Our objective was to survey the SAGES membership regarding guidelines’ quality, use, and value and identify topics of interest for new guideline development. An anonymous online survey was emailed in October 2019 to SAGES members. Respondents were asked 18 questions on their use and evaluation of SAGES guidelines and SAGES reviews and to provide suggestions for new guideline topics and areas of improvement. The survey was open for 6 weeks with a 3-week reminder. Of 548 responders, most were minimally invasive (41%) or general surgeons (33%). There was an even distribution between academic (46%) and non-academic practice (24% private practice, 23% hospital employed). Most used SAGES guidelines frequently (22%) or occasionally (68%) and found them to be of value (83%), above average quality (86%), and easy to use (74%). While most stated it was important (35%) or very important (58%) that SAGES continues to follow “rigorous guidelines development processes,” common suggestions were for more timely updates and improved web access. Of 442 overlapping topic suggestions, 60% fell into overarching categories of hernia, bariatric, robotic, HPB, and colorectal surgery. The SAGES guidelines are used frequently and valued by its users for their quality and content. Topics proposed by SAGES members and valuable insight from this survey can guide creation of new guidelines and refinement of established guidelines and processes.

Patients with adjustable gastric banding (AGB) often require revision to one-stage or two-stage sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB).To compare the long-term durability of revisional SG and RYGB, in terms of subsequent revision or conversion (RC).The New York Statewide Planning and Research Cooperative Systems dataset was queried from 2006 to 2013 for patients who underwent primary SG and RYGB, one-stage, and two-stage conversion from AGB to SG and RYGB. Patients who required RC were identified. A multivariable Cox proportional hazard model was used to compare the RC risk among these groups.13,749 had primary SG, 621 one-stage, and 321 two-stage AGB to SG. 31,814 had primary RYGB, 555 one-stage, and 248 two-stage AGB to RYGB. The estimated 5-year cumulative RC incidence rate was significantly lower after primary surgery than after prior AGB (one-stage AGB to SG 14.4%, two-stage AGB to SG 11.6%, primary SG 5.2%, one-stage AGB to RYBG 3.4%, two-stage AGB to RYGB 2.9%, and primary RYGB 1.1%, p-value 0.0001). RYGB and SG did not differ significantly in terms of the elevation effect of one- and two-stage AGB conversion over primary surgeries (RYGB vs SG: one stage vs primary ratio of HR = 0.97, 95% CI = [0.58, 1.63], p-value = 0.9153; two stage vs primary ratio of HR = 1. 02, 95% CI = [0.50, 2.07], p-value = 0.9596).RC after AGB to SG or RYGB is more frequent compared to primary surgeries with procedures following AGB to SG being more common than AGB to RYGB. However, that difference was proportionally similar to the RC rate ratio differences noted for primary SG and RYGB.

Achalasia is an esophageal motility disorder characterized by disordered esophageal peristalsis with failed relaxation of the lower esophageal sphincter resulting in a functional obstruction.Treatment can include medical, endoscopic, or surgical interventions. Although none of these are curative, they each offer methods to create esophageal outflow.This article discusses our preferred surgical technique used for laparoscopic Heller myotomy with Dor fundoplication. This technique has been developed over the author's career.The technique discussed provides a safe and effective strategy to manage achalasia.

The Fellowship Council (FC) is transitioning to a competency-based medical education (CBME) model, including the introduction of Entrustable Professional Activities (EPAs) for training and assessment of Fellows. This study describes the implementation process employed by the FC during a ten-month pilot project and presents data regarding feasibility and perceived value.The FC coordinated the development of EPAs in collaboration with the sponsoring societies for Advanced GI/MIS, Bariatrics, Foregut, Endoscopy and Hepatopancreaticobiliary (HPB) fellowships encompassing the preoperative, intraoperative, and postoperative phases of care for key competencies. Fifteen accredited fellowship programs participated in this project. The assessments were collected through a unique platform on the FC website. Programs were asked to convene a Clinical Competency Committee (CCC) on a quarterly basis. The pilot group met monthly to support and improve the process. An exit survey evaluated the perceived value of EPAs.The 15 participating programs included 18 fellows and 106 faculty. A total of 655 assessments were initiated with 429 (65%) completed. The average (SD) number of EPAs completed for each fellow was 24(18); range 0-72. Intraoperative EPAs were preferentially completed (71%). The average(SD) time for both the fellow and faculty to complete an EPA was 27(78) hours. Engagement increased from 39% of fellows completing at least one EPA in September to 72% in December and declining to 50% in May. Entrustment level increased from 6% of EPAs evaluated as "Practice Ready" in September to 75% in June. The exit survey was returned by 63% of faculty and 72% of fellows. Overall, 46% of fellows and 74% of program directors recommended full-scale implementation of the EPA framework.A competency-based assessment framework was developed by the FC and piloted in several programs. Participation was variable and required ongoing strategies to address barriers. The pilot project has prepared the FC to introduce CBME across all FC training programs.

Background Some bariatric procedures have been associated with increased gastroesophageal reflux disease (GERD) symptoms; however, there are limited data on the long-term changes to the esophagus across bariatric procedures, and how preoperative esophageal disease is impacted by bariatric surgery. Objectives To estimate incidence of GERD, esophagitis, Barrett's esophagus, and esophageal adenocarcinoma before and after bariatric surgery and to identify potential risk factors for these conditions. Setting Retrospective analysis of New York State Database (SPARCS). Methods Adult patients undergoing bariatric surgery (Roux-en-Y gastric bypass, adjustable gastric banding, laparoscopic sleeve gastrectomy, and biliopancreatic diversion) from 1995 to 2010. Multivariable Cox proportional hazard models were used to examine the association between preoperative diagnosis, surgery type, and postoperative diagnosis. Results A total of 48,967 records were analyzed; 30.3% had a diagnosis of GERD at the time of surgery and .4% had a diagnosis of esophagitis and Barrett's. Preoperative GERD/esophagitis/Barrett's was associated with higher risk of GERD, esophagitis, and Barrett's, but not esophageal adenocarcinoma, postoperatively. Roux-en-Y gastric bypass patients had lowest risk of being diagnosed with GERD postoperatively. Overall, esophageal adenocarcinoma incidence in the sample was .04%; the rate among patients with preoperative GERD and Barrett's was .1% and .9%, respectively. Incidence of esophageal adenocarcinoma did not differ by bariatric surgery type. Conclusions Preoperative diagnosis is a risk factor for postoperative esophageal disease after bariatric surgery. Adjustable gastric banding and laparoscopic sleeve gastrectomy are associated with higher risk of postoperative GERD and esophagitis compared with Roux-en-Y gastric bypass. Incidence of esophageal adenocarcinoma did not differ by surgery type.

Objective: This study aims to show how full-time telemedicine adoption has impacted patient visit volume and attendance in a comprehensive metabolic and weight loss center. Summary Background Data: Elective surgical practices have been profoundly impacted by the global COVID-19 pandemic, leading to a rapid increase in the utilization of telemedicine. The abrupt initiation of audio-video telehealth visits for all providers of a multidisciplinary clinic on March 19th 2020 provided unique circumstances to assess the impact of telemedicine. Methods: Data from the clinical booking system (new patient and follow-up visits) for all clinical provider types of the multidisciplinary metabolic center from the pre-telehealth, post-telehealth, and a 2019 comparative period were retrospectively reviewed and compared. The primary outcome is the change in patient visit volume for all clinical providers from before to after the initiation of telemedicine for both new patient, and follow-up visits. Results: There were a total of 506 visits (162 new patient visits, and 344 follow-ups) in the pre-telehealth period, versus 413 visits (77 new patient visits, and 336 follow-ups) during the post-telehealth period. After telehealth implementation, new visits for surgeons decreased by 75%. Although follow-up visits decreased by 55.06% for surgeons, there was an increase by 27.36% for advanced practitioners. When surgeons were separated from other practitioners, their follow-up visit rate decrease by 55.06%, compared to a 16.08% increase for the group of all other practitioners (P < 0.0001). Dietitians experienced higher rates of absenteeism with new patient visits (10.00% vs 31.42%, P = 0.0128), whereas bariatricians experienced a decrease in follow-up visit absenteeism (33.33% vs 0%, P = 0.0093). Conclusions: Although new patient visit volume fell across the board, follow-up visits increased for certain nonsurgical providers. This provides a template for adoption of a multidisciplinary telehealth clinic in a post-pandemic world.

Even though acute appendicitis is the most common general surgical condition encountered during pregnancy, the preferred approach to appendectomy in pregnant patients remains controversial. Current guidelines support laparoscopic appendectomy as the treatment of choice for pregnant women with appendicitis, regardless of trimester. However, recent published data suggests that the laparoscopic approach contributes to higher rates of fetal demise. Our study aims to compare laparoscopic and open appendectomy in pregnancy at a statewide population level. ICD-9 codes were used to extract 1006 pregnant patients undergoing appendectomy between 2005 and 2014 from the NY Statewide Planning and Research Cooperative System (SPARCS) database. Surgical outcomes (any complications, 30-day readmission rate, length of stay (LOS)) and obstetrical outcomes (antepartum hemorrhage, preterm delivery, cesarean section, sepsis, chorioamnionitis) were compared between open and laparoscopic appendectomy. Multivariable generalized linear regression models were used to compare different outcomes between two surgical approaches after adjusting for possible confounders. The laparoscopic cohort (n = 547, 54.4%) had significantly shorter LOS than the open group (median ± IQR: 2.00 ± 2.00 days versus 3.00 ± 2.00 days, p value

Although bariatric surgery is associated with multiple health benefits, decreased bone mass is a known complication of the procedure. Roux-en-Y gastric bypass (RYGB) is associated with significant bone loss and increased fracture risk. However, data on the effect of sleeve gastrectomy (SG) on bone mineral changes are sparse. The impact of vitamin D and calcium levels on bone mineral density (BMD) after SG is also unknown. A retrospective chart review was performed to include patients who underwent RYGB or SG from 2014 to 2016 at a single institution. Patients were included if bone densitometry was performed preoperatively and within 2 years postoperatively. Serum 25-hydroxy vitamin D and calcium levels were collected preoperatively and at time of bone densitometry scan. BMD and T-score changes at the femoral neck, femoral trochanter, total hip, and lumbar spine were compared between RYGB and SG patients. A total of 40 patients were included. 24 (60%) of patients underwent RYGB and 16 (40%) patients underwent SG. No statistically significant difference in baseline characteristics was noted between RYGB and SG patients. All measurements, except for serum 25-hydroxy vitamin D, were significantly decreased in RYGB patients, postoperatively. All measurements, except for BMD and T-score at the lumbar spine and serum 25-hydroxy vitamin D, were significantly decreased in SG patients, postoperatively. The extent of decrease in serum 25-hydroxyvitamin D was significantly associated with decreased BMD (p = 0.049) and T-score (p = 0.032) at the lumbar spine. The extent of decrease in serum calcium was significantly associated with decreased BMD (p = 0.046) at the femoral neck. All patients were found to have decreased BMD after RYGB and SG. Surgery type was not a significant risk factor in BMD change. Despite vitamin D and calcium supplementation in all patients, a decrease in vitamin D and calcium levels were associated with a decrease in BMD. Close follow-up and treatment of vitamin D and calcium levels are warranted in all bariatric patients.

Hospital readmissions constitute an important component of associated costs of a disease and can contribute a significant burden to healthcare. The majority of studies evaluating readmissions following laparoscopic cholecystectomy (LC) comprise of single center studies and thus can underestimate the actual incidence of readmission. We sought to examine the rate and causes of readmissions following LC using a large longitudinal database. The New York SPARCS database was used to identify all adult patients undergoing laparoscopic cholecystectomy for benign biliary disease between 2000 and 2016. Due to the presence of a unique identifier, patients with readmission to any New York hospital were evaluated. Planned versus unplanned readmission rates were compared. Following univariate analysis, multivariable logistic regression model was used to identify risk factors for unplanned readmissions after accounting for baseline characteristics, comorbidities and complications. There were 591,627 patients who underwent LC during the studied time period. Overall 30-day readmission rate was 4.94% (n = 29,245) and unplanned 30-days readmission rate was 4.58% (n = 27,084). Female patients were less likely to have 30-day unplanned readmissions. Patients with age older than 65 or younger than 29 were more likely to have 30-day unplanned readmissions compared to patients with age 30–44 or 45–64. Insurance status was also significant, as patients with Medicaid/Medicare were more likely to have unplanned readmissions compared to commercial insurance. In addition, variables such as Black race, presence of any comorbidity, postoperative complication, and prolonged initial hospital length of stay were associated with subsequent readmission. This data show that readmissions rates following LC are relatively low; however, majority of readmissions are unplanned. Most common reason for unplanned readmissions was associated with complications of the procedure or medical care. By identifying certain risk groups, unplanned readmissions may be prevented.

Current guidelines support laparoscopic cholecystectomy as the treatment of choice for pregnant women with symptomatic gallbladder disease, regardless of the trimester. Early intervention has remained the standard of care, but recent evidence has challenged this practice in pregnant women. We sought to compare surgical and maternal–fetal outcomes of antepartum versus postpartum cholecystectomy in New York State. Between 2005 and 2014, the New York Statewide Planning and Research Cooperative System (SPARCS) database was queried for patients who underwent cholecystectomy within 3 months before (antepartum cholecystectomy, APCCY: n = 82) and after (postpartum cholecystectomy, PPCCY: n = 5040) childbirth to approximate third-trimester operations. All patients who underwent cholecystectomy during pregnancy (n = 971) were extracted to evaluate inter-trimester differences. Subgroup analysis compared APCCY patients who were not hospitalized within 1 year before APCCY (n = 80) and PPCCY patients who were hospitalized within 1 year before childbirth (n = 29) for symptomatic biliary disease. Multivariable generalized linear regression models were used to characterize the association between timing of cholecystectomy and several primary outcomes: length of stay (LOS), 30-day non-pregnancy, non-delivery readmission (NPND), bile duct injury (BDI), composite maternal outcome (antepartum hemorrhage, preterm delivery, cesarean section), any complications, and fetal demise. Third-trimester APCCY women had longer LOS (Ratio: 1.44, 95% CI [1.26–1.66], p

Obesity is a known risk factor for many cancers. Although bariatric surgery has been associated with a decrease in the risk of developing cancer, data on the effect of bariatric surgery on female-specific cancers are limited. This study aimed to assess the impact of bariatric interventions on the development of endometrial, ovarian and breast cancer. The New York Statewide Planning and Research Cooperative System database was used to identify all female patients without a pre-existing cancer diagnosis who had a diagnosis of obesity between 2006 and 2012. The risk of having female-specific cancer diagnosis in patients who underwent bariatric surgery were compared with those who had no bariatric interventions using multivariable proportional sub-distribution hazard regression analysis. Subsequent cancer diagnoses were followed up to 2016. We identified 55,781 and 247,102 obese female patients who had and did not have bariatric surgery, respectively. The overall incidence of female-specific cancer was 2.69% and 2.09% for the non-surgery and surgery groups, respectively (p

The American Cancer Society recently lowered the recommended age for screening of colorectal cancer (CRC) to age 45 due to recent data showing increased incidence of CRC in younger populations. The purpose of this study was to evaluate if younger patients have increased likelihood of resection for CRC through the use of a statewide longitudinal database. The New York SPARCS administrative database was used to identify all patients with diagnosis of colon cancer undergoing colorectal resections from 2000 to 2016. Patients were divided into seven age groups. Patients’ characteristics, demographics, co-morbidities, and complications were evaluated. Chi-square test was used to compare patients’ characteristics, comorbidities and complications among age groups. The linear trend of colon resection in different age groups over years was examined using log-linear Poisson regression models with year as an explanatory variable, as well as using multivariable logistic regression models after adjusting for patients’ gender, race, payment, region, any comorbidity and any complication. There were 73,697 colon resection surgeries extracted from 2000 to 2016. Younger age was significantly associated with increased colorectal cancer resection over time. Patients age 21–70 had a significantly increasing trend over the years (age group 21–30: RR 1.06, p-value 70 was significantly associated with decreasing trend of colorectal cancer resection over the years (age group 71–80: RR 0.98, p 80: RR 0.99, p-value

While bariatric surgery has been shown to improve type 2 diabetes (DM) control in the obese population, the effect on long-term DM complications has been less thoroughly investigated. The purpose of this study was to assess the development of microvascular and macrovascular complications in obese DM patients undergoing bariatric surgery. New York patients’ records from the SPARCS database in years 2006–2012 were used to identify obese patients with DM. Patients undergoing bariatric surgery were compared with patients managed medically, matched for age and gender. Patients were grouped based on baseline presence of controlled or uncontrolled DM and followed over time for the development of micro- and macrovascular complications. Cumulative incidence of complications was estimated with death treated as a competing risk event. Multivariable proportional sub-distribution hazards models were used to compare the risk of complications among different patient groups after adjusting for possible confounding factors. A total of 88,981 patients were reviewed, including 15,585 (18%) that were treated with bariatric surgery. Surgery patients had significantly lower risk of microvascular complications compared to non-surgery patients (controlled diabetes: HR = 0.40, 95% CI 0.37–0.42; uncontrolled diabetes: HR = 0.51, 95% CI 0.37–0.71). Similarly, the surgical patients were noted to have a significantly lower risk for macrovascular complications compared to non-surgery patients (controlled diabetes: HR = 0.43, 95% CI 0.40–0.46; uncontrolled diabetes: HR = 0.44, 95% CI 0.28–0.69). Cumulative incidence of microvascular complications was lower at 1, 5 and 9 years for the surgical groups for controlled and uncontrolled DM. Similar trends were observed for the macrovascular complications. Bariatric surgery appears to prevent complications of DM. Bariatric surgery patients with DM experienced significantly lower rates of microvascular and macrovascular complications, compared to non-surgically treated comparison group. Bariatric surgery was noted to offer protective benefits for both complicated and non-complicated DM patients. This reduced rate of complications was sustained in the long term.

Background Surgeons are trained as “internists that also operate,” bringing an important skillset to patient management during the current COVID-19 pandemic. A review was performed to illustrate the response of surgical staff during the pandemic with regard to patient care and residency training. Methods The evaluation and assessment of the changes enacted at Stony Brook Medicine’s Department of Surgery is illustrated through the unique perspective of surgical residents. No IRB approval or written consent was obtained nor it was necessary for the purposes of this paper. Results Hospital policy was enacted to hinder transmission of COVID-19 and included limited gatherings of people, restricted travel, quarantined symptomatic staff, and careful surveillance for disease incidence. Surgical residency transformed as residents were diverted from traditional surgical services to staff new COVID-19 ICUs. Education transitioned to an online-based platform for lectures and reviews. New skills sets were acquired such as PICC line placement and complex ventilator management. Conclusions The viral surge impacted surgical training while also providing unique lessons regarding preparedness and strategic planning for future pandemic and disaster management.

Small Bowel Obstruction (SBO) is a common reason for emergency department (ED) visits in the United States. However, little is known regarding the clinical course of these patients. This study aims to identify all patients presenting to the ED in New York State with SBO and follow their clinical course. The New York SPARCS administrative database was used to identify all patients who presented to an ED with the diagnosis of SBO from 2012 to 2014. Patients were followed to identify discharges from the ED, admissions, operations, 30-day readmissions, transfers, and in-hospital death. Between 2012 and 2014, 43,567 ED visits (events) from 35,646 patients were identified, with 2824 (6.5%) resulting in direct discharge from the ED. A majority (n = 31,193; 71.6%) of ED visits were admitted to the presenting institution without surgery, while 7673 (17.6%) were admitted and underwent surgery. A minority (n = 1947; 4.5%) were transferred to a tertiary center. The overall 30-day readmission rate was 17.9%. Those who underwent surgery were more likely to experience in-hospital death but less likely to have 30-day readmission. To our knowledge, this is the first study that examines the disposition of all patients presenting to the ED with SBO in a large statewide cohort. The majority of admitted patients underwent non-operative management, with overall low rates of readmission, transfer, and in-hospital death.

While laparoscopic sleeve gastrectomy (LSG) has recently emerged as the predominant surgery type for the national bariatric cohort, the literature suggests that laparoscopic Roux-en-Y gastric bypass (LRYGB) may be more effective in normalizing gastroesophageal physiology for the subset of patients with GERD. This study explored practice patterns over time for patients with GERD or hiatal hernia, a related comorbidity, undergoing bariatric surgery. Data for LSG and LRYGB were extracted from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) datasets for 2015–2018. Multivariable logistic regression analyses were performed to determine the effects of pre-existing GERD or concomitant hiatal hernia repair on surgery type. A total of 130,772 patients underwent LRYGB (30.5%) or LSG (69.5%) in 2015, which increased year-to-year to 161,275 patients in 2018 (74.61% LSG). A total of 38.4% LRYGB patients had pre-existing GERD vs. 27.55% LSG patients. Patients with pre-existing GERD were increasingly likely to undergo LRYGB vs. those without GERD (OR 1.205 [95% CI 1.17–1.24] in 2015 vs. OR 1.510 [95% CI 1.47–1.55] in 2018, p

Socioeconomic factors predispose certain populations to an increased exposure to emergent operative procedures. The aim of this study is to evaluate the role socioeconomic factors play in emergent repairs of inguinal, ventral and umbilical hernias. The SPARCS database was used to identify all patients undergoing emergent ventral hernia repair (EVR), emergent inguinal hernia repair (EIR), and emergent umbilical hernia repair (EUR) between 2008 and 2015. Chi-square test with exact p values from Monte Carlo simulation determined marginal associations between repairs (elective vs. emergent), and patient characteristics and comorbidities. Multivariable logistic regression models were further utilized to examine socioeconomic disparity. 107,887 ventral hernias, 66,947 inguinal hernias, and 63,515 umbilical hernias (total 238,349) were noted. African Americans were most likely to undergo an EVR compared to Caucasians (OR 1.55, 95% CI: 1.48–1.61), Asians (OR 1.31, 95% CI: 1.15–1.5), and Hispanics (OR 1.3, 95% CI: 1.23–1.37). African Americans were most likely to undergo EIR compared to Caucasians (OR 2.2, 95% CI: 2.06–2.36), Asians (OR 1.74, 95% CI: 1.49–2.02), and Hispanics (OR 1.22, 95% CI: 1.12–1.34). African Americans were most likely to undergo EUR compared to whites (OR 1.29, 95% CI: 1.22–1.36), Asians (26.62%, OR 1.21, 95% CI: 1.01–1.46) and Hispanic (28.03%, OR 1.08, 95% CI: 1.01–1.16). Medicaid patients were also more likely to undergo EVR (OR 1.31, OR 1.73), EIR (OR 2.92, OR 4.55) and EUR (OR 1.63, OR 2.31) compared to Medicare and commercial insurance. Race is a contributing factor in who undergoes an emergent hernia repair in New York State. A significantly larger proportion of the African American population is undergoing hernia repair in the emergent setting. Socioeconomic status, as indicated by the significant number of Medicaid patients undergoing emergent hernia repairs, also plays a role.

While guidelines exist for the management of postoperative nausea and vomiting (PONV) in the general surgical setting, there are no established guidelines for the prevention or treatment of PONV in bariatric patients, in whom PONV contributes significantly to perioperative morbidity and hospital resource utilization. This systematic review found that the multimodal pharmacological approach to PONV prevention recommended in current guidelines for high-risk surgical patients is appropriate for the bariatric subset. This includes multi-agent antiemetic prophylaxis with dexamethasone and one or more agents from other classes, and opioid-free total intravenous anesthesia, though the advantages of the latter need further evaluation. There remains a need for a standardized validated instrument to assess PONV in the bariatric setting.

Despite an increase in percentage of women entering the surgical field, women tend to favor certain surgical subspecialties. The purpose of this study was to investigate how surgeons advise trainees in pursuit of a surgical career. An 18-question survey was administered to members of the American College of Surgeons through their monthly newsletter NewScope. Respondents were asked to identify subspecialties that they would consider to be most receptive to men or women and how they would advise men and women pursuing a surgical specialty. There were 663 respondents, of which the majority (n = 465, 70.99%) were male. When asked if participants had a role model in medical school, 61.10 per cent had male role models/mentors, whereas only 7.96 per cent had female role models/mentors. Among the 23 surgical subspecialties listed, the top five specialties viewed as receptive for women were breast surgery, obstetrics and gynecology, plastic surgery, ophthalmology, and GS. Surgical specialty and gender of the respondent played a role in how surgeons advised men and women trainees, especially in specialties that traditionally have less female representation. There is inherent gender-based bias in advisement of trainees that may affect surgical specialty choice. Surgeon gender, age, and surgical specialty could be predictors as to how trainees are advised.

Introduction: Globally, 300 million adults have clinical obesity. Heightened adiposity and inadequate musculature secondary to obesity alter bipedal stance and gait, diminish musculoskeletal tissue quality, and compromise neuromuscular feedback; these physiological changes alter stability and increase injury risk from falls. Studies in the field focus on obese patients across a broad range of body mass indices (BMI >30 kg/m2) but without isolating the most morbidly obese subset (BMI ≥40 kg/m2). We investigated the impact of obesity in perturbing postural stability in morbidly obese subjects elected for bariatric intervention, harboring a higher-spectrum BMI. Subjects and Methods: Traditional force plate measurements and stabilograms are gold standards employed when measuring center of pressure (COP) and postural sway. To quantify the extent of postural instability in subjects with obesity before bariatric surgery, we assessed 17 obese subjects with an average BMI of 40 kg/m2 in contrast to 13 nonobese subjects with an average BMI of 30 kg/m2. COP and postural sway were measured from static and dynamic tasks. Involuntary movements were measured when patients performed static stances, with eyes either opened or closed. Two additional voluntary movements were measured when subjects performed dynamic, upper torso tasks with eyes opened. Results: Mean body weight was 85% (p < 0.001) greater in obese than nonobese subjects. Following static balance assessments, we observed greater sway displacement in the anteroposterior (AP) direction in obese subjects with eyes open (87%, p < 0.002) and eyes closed (76%, p = 0.04) versus nonobese subjects. Obese subjects also exhibited a higher COP velocity in static tests when subjects’ eyes were open (47%, p = 0.04). Dynamic tests demonstrated no differences between groups in sway displacement in either direction; however, COP velocity in the mediolateral (ML) direction was reduced (31%, p < 0.02) in obese subjects while voluntarily swaying in the AP direction, but increased in the same cohort when swaying in the ML direction (40%, p < 0.04). Discussion and Conclusion: Importantly, these data highlight obesity’s contribution towards increased postural instability. Obese subjects exhibited greater COP displacement at higher AP velocities versus nonobese subjects, suggesting that clinically obese individuals show greater instability than nonobese subjects. Identifying factors contributory to instability could encourage patient-specific physical therapies and presurgical measures to mitigate instability and monitor postsurgical balance improvements.

This study aims to compare the timing of interval appendectomy (IA) and its impact on post-operative outcomes.A retrospective analysis was performed for adult patients diagnosed with appendicitis between 2006 and 2017. IA was defined as a follow-up appendectomy 1 week and 2 years after the initial presentation. Time intervals were divided into 4 groups based on patient quartiles: 1-6 weeks, 7-9 weeks, 10-15 weeks, and 15 weeks. The primary outcome measure was length of stay (LOS). Secondary outcomes included 30-day readmission and IA post-operative complications. Tertiary outcomes included 30-day mortality and colonoscopy suggesting neoplasm or Inflammatory Bowel Disease.A total of 5069 patients' records whose interval appendectomy fell 1 week and 2 years after initial presentation were analyzed. Among them, 1006 (19.85%) underwent an initial percutaneous abscess drainage at diagnosis. The median timing for IA was 9.2 weeks. Patients with IA at 1-6 weeks were more likely to have longer LOS when compared to 7-9 weeks (ratio 1.33, 95% CI 1.2-1.48) and 10-15 weeks (ratio 1.38, 95% CI 1.25-1.52). IA between 7 and 9 weeks (ratio 0.81, 95% CI 0.73-0.89) and 10-15 weeks (ratio 0.78, 95% CI 0.71-0.86) was associated with significantly shorter LOS compared to those receiving the operation after 15 weeks. Further, patients requiring abscess drainage (ratio 1.2, 95% CI 1.13-1.34) or those with comorbidities (ratio 1.51, 95% CI 1.39-1.63) were more likely to have longer LOS at IA. Socioeconomic and demographic differences including Black, Hispanic, and those with Medicare and Medicaid insurance had a greater LOS after their IA.LOS remains lowest among patients undergoing IA between 7-9 weeks and 10-15 weeks after initial appendicitis presentation. Patients with lower socioeconomic status or from racial minorities had a longer LOS after IA.

SARS-CoV-2 has changed global healthcare since the pandemic began in 2020. The safety of minimally invasive surgery (MIS) utilizing insufflation from the standpoint of safety to the operating room personnel is currently being explored. The aims of this guideline are to examine the existing evidence to provide guidance regarding MIS for the patient with, or suspecting of having, the SARS-CoV-2 as well as the healthcare team involved.Systematic literature reviews were conducted for 2 key questions (KQ) regarding the safety of MIS in the setting of COVID-19 pandemic. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis criteria. Evidence-based recommendations were formulated using a narrative synthesis of the literature by subject experts. Recommendations for future research were also proposed.In KQ1, a total of 1361 articles were reviewed, with 2 articles meeting inclusion. In KQ2, a total of 977 articles were reviewed, with 4 articles met inclusions criteria, of which 2 studies reported on the SARS-CoV2 virus specifically. Despite many publications in the field, very little well-controlled and unbiased data exist to inform the recommendations. Of that which is available, it shows that both laparoscopic and open operations in Covid-positive patients had similar rates of OR staff positivity rates; however, patients who underwent laparoscopic procedures had a lower perioperative mortality than open procedures. Also, SARS-CoV-2 particles have been detected in the surgical plume at laparoscopy.With demonstrated equivalence of operating room staff exposure, and noninferiority of laparoscopic access with respect to mortality, either laparoscopic or open approaches to abdominal operations may be used in patients with SARS-CoV-2. Measures should be employed for all laparoscopic or open cases to prevent exposure of operating room staff to the surgical plume, as virus can be present in this plume.

For organ-confined prostate cancer, socioeconomic factors influencing Magnetic Resonance Imaging (MRI)-guided biopsy utilization and downstream prostate cancer patients' care are unknown. This retrospective, observational cohort study used the New York Statewide Planning and Research Cooperative System (SPARCS) billing-code driven database to examine the impact of prostate patients' socioeconomic characteristics on prostate cancer care defined as initial biopsy, 2-month post-biopsy cancer diagnoses, and within 1-year cancer-related intervention, controlling for other risk factors. From 2011-2017, the population studied (n = 18,253) included all New York State-based, male, residents aged 18 to 75 without a prior prostatectomy receiving a first-time biopsy; 760 such patient records in 2016 were removed due to data quality concerns. Major exposures included patient age, race, ethnicity and insurance. The major outcome included receipt of MRI biopsy versus standard biopsy and for these sub-populations, subsequent 2-month post-biopsy metastatic versus non-metastatic prostate cancer diagnosis and within 1-year prostate cancer treatment (prostatectomy with or without radiation versus prostatectomy-only) were compared using dichotomous (primary) and time-to-event (secondary) endpoints. Of 17,493 patients with a first-time prostate biopsy, 3.89% had MRI guided biopsies; of the 17,128 patients with no pre-biopsy cancer diagnosis, the subsequent prostate cancer diagnosis rate was 42.59%. For 6,754 non-metastatic prostate cancer patients with 1-year follow-up, 1,674 (24.79%) received surgery (with or without radiation) and 495 (7.33%) received radiation-only. Holding other factors constant, multivariable regression models identified that race-insurance was a primary predictor of MRI-guided biopsy use. Compared to commercially insured White patients, Black patients across all insurance categories received MRI-guided biopsies less frequently; Commercially insured and self-pay Black patients also had increased chance of prostate cancer diagnosis. Across all insurers, Black patients had lower likelihood of prostatectomies. In contrast, Black and White patients with government insurance were more likely to have within 1-year radiation-only treatments versus commercially insured White patients. Thus, across the prostate cancer care continuum, race-insurance affected prostate cancer-related service utilization. Future research should evaluate the generalizability of these New York State findings.

Management of patients on chronic anticoagulation (AC) in bariatric surgery may present a challenge, as there is a delicate balance between risks of bleeding and thrombotic events, such as deep vein thrombosis (DVT) and pulmonary embolism (PE). The purpose of this study was to evaluate and compare rates of bleeding, thrombotic events, and outcomes of patients on preoperative AC during bariatric surgery. The MBSAQIP data sets for 2015 and 2016 was used to identify all patients undergoing adjustable gastric banding (AGB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB). Clinical outcomes included length of stay, 30-day readmission, 30-day reoperations and interventions, perioperative and 30-day death events, need for transfusion, PE, and DVT. Following univariate analysis, multivariable logistic regression models and generalized linear regression model for a negative binomial distributed count outcomes were used after adjusting for surgery type and other factors related to each outcome. There were 269,243 records extracted, as there were 6541 (2.43%) patients on preoperative AC. Rates of transfusion, DVT, and PE were 0.67%, 0.18%, and 0.11%. Following multivariable logistic regression, patients with preoperative AC had higher risks of bleeding and DVT (OR 2.7, 95% CI 2.3–3.3, p-value

There is limited data examining specific annual surgeon procedural volumes associated with improvement of postoperative outcomes following Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). Effect of surgeon volume on procedural outcomes. Using the SPARCS Administrative database, patients undergoing laparoscopic RYGB or SG between 2010–2014 were analyzed. Multivariable generalized linear mixed regression models were first used to analyze the influences of 3 yearly mean volumes (combined, RYGB and SG mean volumes) on each of three surgical outcomes: 30-day readmission, peri-operative complications, and extended length of stay (LOS), while accounting for patient specific variables. A total of 46,511 laparoscopic bariatric procedures were included in the study. Risk for any complication and 30-day readmissions following RYGB decreased with increasing RYGB volume up to a specific volume and stayed similar afterward (OR 0.97, 95% CI 0.96–0.98 while volume 138 cases/year)). Bariatric procedure peri-operative outcomes are affected by procedure-specific annual surgeons’ volume.

The timing of cholecystectomy for acute cholecystitis has been debated with most studies favoring early cholecystectomy (
