RESUMEN

BACKGROUND: We previously showed worse outcomes among lower socioeconomic status (SES) groups following metabolic/bariatric surgery (MBS). In light of healthcare changes in response to COVID-19, this study aims to evaluate post-pandemic MBS outcomes and determine if prior socioeconomic disparities persisted in the post-COVID era. METHODS: A retrospective chart review of patients undergoing primary Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) between 2015 and 2022 was performed. Patients were stratified into pre- and post-COVID groups. Post-COVID cohort was further stratified into high (HT) and low (LT) tier status based on Distressed Communities Index, a geocoded composite measure of SES. Preoperative characteristics and postoperative outcomes were compared between pre- and post-COVID cohorts, as well as between post-COVID HT and LT groups. RESULTS: Of 709 patients, 82.9% were pre-COVID and 17.1% were post-COVID. Post-COVID cohort had greater rate of public insurance (46% vs. 37%, p < 0.001), longer wait time to surgery (mean 358 ± 609.8 days vs 241.9 ± 368.5 days, p = 0.045), and were more likely to undergo RYGB (69% vs. 56%, p = 0.010). Post-COVID patients also had lower risk of any complications on multivariable analysis (OR 0.599, 95% CI 0.372-0.963), had higher follow-up rates at post-discharge (95.8% vs 79.7%, p < 0.005), 6-month (93% vs. 82%, p < 0.001) and 12-month visits (75% vs. 63%, p = 0.005), and lost more weight at 12 months (67% excess weight loss (%EWL) vs. 58%EWL, p = 0.002). Among post-COVID HT and LT cohorts, previously seen disparities in complications were no longer seen. Finally, there were no differences in weight or follow-up rates between post-COVID HT and LT. CONCLUSIONS: Post-COVID changes to MBS care have resulted in improved short-term outcomes and reduced disparities for patients of lower SES. Further studies are needed to identify these positive factors to perpetuate practice patterns that optimize care for patients of all socioeconomic status.

RESUMEN

Introduction While surgical indications for symptomatic cholelithiasis and biliary hypokinesia are clear, hyperkinetic biliary dyskinesia (HBD) is an underrecognized condition with poorly defined symptomology and management guidelines. HBD is typically defined as a gallbladder ejection fraction (EF) ≥ 80% on a hepatobiliary iminodiacetic acid (HIDA) scan. We aimed to identify the prevalence and radiographic reporting of HBD, physician referral patterns, and clinical outcomes following cholecystectomy. Methods  A retrospective cohort study of patients with HIDA scans completed over 21 years at our tertiary care hospital was performed. Demographics, symptomatology, referral patterns, and operative data were collected. HBD was defined as HIDA EF ≥80%. Patients with HBD who underwent cholecystectomy were analyzed. ANOVA and chi-square tests were used to compare variables among patients with or without symptom improvement using Statistical Product and Service Solutions (SPSS; IBM SPSS Statistics for Windows, Armonk, NY). Results Of 1,997 patients (73% female, mean age 51.7 years) who had HIDA scans with reported EF, 730 (36.6%) had an EF≥80%. Only 13.7% of HIDA scans with EF≥80% were reported as hyperkinetic, and the rest are "normal". Cholecystectomy was performed in 57 (7.8%) patients with EF≥80%, most being elective (89.5%) and all minimally invasive. Primary care physicians (PCPs) referred most elective cases to surgery (61.4%). The median time from HIDA to cholecystectomy was 146 days. Chronic cholecystitis was common in pathology (82.5%), while 38.6% had cholelithiasis. Overall, 53 patients (93.0%) reported symptom improvement at a median follow-up of 17.0 days. Patients without improvement had a higher prevalence of chronic gastrointestinal conditions (p<0.05), but not significantly more cholelithiasis, cholecystitis, time to surgery, or elective surgery status. Conclusions HBD is common but often underdiagnosed and thus likely underrecognized by treating physicians. Most HBD patients benefit from cholecystectomy, regardless of cholelithiasis. Patients with persistent symptoms after cholecystectomy may have confounding gastrointestinal diagnoses. Increased awareness among radiologists, referring PCPs, gastroenterologists, and surgeons about HBD and postoperative outcomes is needed to ensure that HBD is adequately treated.

RESUMEN

BACKGROUND: Socioeconomic status (SES) is multifactorial, and its effect on post-bariatric weight recurrence is unclear. Distressed Community Index (DCI) is a composite SES score measuring community economic well-being. This study aims to evaluate the effect of DCI on long-term post-bariatric weight outcomes. METHODS: Retrospective analysis of patients undergoing primary laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy between 2015 and 2020 was performed. All weights in the electronic medical record (EMR), including non-bariatric visits, were captured. Patients were stratified into low tier (LT) and high tier (HT) DCI groups. RESULTS: Of 583 patients, 431 (73.9%) were HT and 152 (26.1%) were LT. Average bariatric follow up was 1.78 ± 1.6 years and average postoperative weight in the EMR was 3.96 ± 2.26 years. Rates of bariatric follow up within the last year were similar (13.8% LT vs 16.2% HT, p = 0.47). LT had higher percent total body weight loss (%TWL; 26% LT vs 23% HT, p < 0.01) and percent excess weight loss (%EWL; 62% vs 57%, p = 0.04) at 1 year on univariate analysis. On multivariate linear regression adjusting for baseline characteristics and surgery type, there were no differences in %EWL between groups at 1 year (p = 0.22), ≥ 3 years (p = 0.53) or ≥ 5 years (p = 0.34) postop. While on univariate analysis LT only trended towards greater percentage of patients with > 15% increase from their 1-year weight (33.3% LT vs 21.0% HT, p = 0.06), on multivariate analysis this difference was significant (OR 2.0, LT 95%CI 1.41-2.84). There were no differences in the percentage of patients with > 15% decrease in %EWL from 1 to 3 + years postop between groups (OR 0.98, LT 95% CI 0.72-1.35). CONCLUSIONS: While low tier patients had similar weight loss at 1 year, they were twice as likely to have weight recurrence at ≥ 3 years. Further studies are needed to identify factors contributing to greater weight recurrence among this population.

RESUMEN

INTRODUCTION: Gastrointestinal symptoms such as diarrhea, bloating, abdominal pain, and nausea are common after bariatric surgery (BS) and can lead to significant morbidity. While many diagnoses can explain these symptoms, post-bariatric exocrine pancreatic insufficiency (EPI) is becoming increasingly recognized as contributor to gastrointestinal symptoms. The frequency and outcomes of EPI after BS are not well understood. We investigated the prevalence and outcomes of EPI over 18 years at a tertiary bariatric referral center. METHODS: A retrospective review of patients who underwent primary or revisional BS from 2002 to 2020 was performed. Patients were included if they were suspected of having EPI or underwent fecal elastase testing (FE-1). EPI diagnosis was defined as positive FE-1 testing or improvement with empiric pancreatic enzyme replacement therapy (PERT). RESULTS: EPI was suspected in 261 patients, and 190 were tested via FE-1 (89.5%) or empirically treated (10.5%). EPI was diagnosed in 79 (41.6%) patients and was associated with older age and lower BMI. Therapeutic PERT was given to 65 patients diagnosed with EPI, and 56 (86.2%) patients reported improved symptoms. Patients who underwent RYGB and BPD-DS were more likely to have EPI than those after SG (47.9% and 70.0% vs 17.4%, p < 0.01). EPI diagnosis was associated with a history chronic pancreatitis. While diarrhea and abdominal pain were the most common symptoms prompting FE-1 testing, no symptoms were significantly associated with EPI. EPI was also associated with abnormal fecal fat results and treatment with bile acid sequestrants, but not small intestinal bacterial overgrowth. CONCLUSION: This study highlights that exocrine pancreatic insufficiency can account to for previously unexplained GI complaints after bariatric surgery. Therefore, bariatric surgery programs should consider this diagnosis in symptomatic patients, especially following RYGB and BPD-DS. Further work to define patient factors that should prompt evaluation, optimal treatment, and prevention is necessary.

RESUMEN

BACKGROUND: Research and history have largely shown the covert billion-dollar global market of single-use medical device (SUD) reprocessing and reuse to be a safe endeavor, but awareness and perceptions of the practice both within and outside of healthcare have received limited attention. METHODS: Responses for patients, physicians, and medical practitioners were attained on both online and article-based surveys, in which attitudes and perceptions of SUD reprocessing and reuse were expressed in an assortment of closed-ended questions and partially closed-ended questions. RESULTS: Of the 214 participants, a collective 77% were unaware that the Food and Drug Administration allows SUD reprocessing and reuse. This included 65% of physicians and 84% of patients, which were significantly different proportions (P = 0.005). A significantly greater proportion of patients than physicians (92 vs. 68%) also felt that hospitals bear the responsibility of informing patients of the practice as part of their care (P < 0.001). CONCLUSION: There is a profound lack of awareness of SUD reprocessing and reuse among all relevant stakeholders. In addition, the overwhelming desire for transparency among patients further forces the debate of whether current, covert methods should be altered, in addition to the question of who bears this responsibility. Despite research and history having shown the practice to be safe, apprehension and misconceptions remain. Survey results suggest that education may be able to subdue such patient concerns.

RESUMEN

BACKGROUND: Sentinel lymph node (SLN) resection is imperative for breast cancer staging. Axillary reverse mapping (ARM) can preserve arm draining nodes and lymphatics during surgery. ARM is generally performed with isosulfan blue (ISB), restricting its use for concurrent SLN biopsy. Indocyanine green (ICG) could serve as an alternative to ISB for ARM procedures. METHODS: SLN mapping and biopsy was performed via periareolar injection of 99 technetium-sulfur colloid (99m TcSc, TSC). ISB and ICG were injected in the upper arm. Blue-stained lymphatics or nodes were visualized in the axilla; ICG was identified using the SPY Elite® system. RESULTS: Twenty-three patients underwent SLN biopsy with or without axillary node dissection and ARM procedures. Twenty of these patients had at least one hot node; 12 patients had SLNs that were only hot, 6 hot/blue/fluorescent, and 2 hot/fluorescent. Overall, crossover of ARM agents with SLNs occurred in 8 cases. Inspection of the axillary cavity after SLN biopsy revealed fluorescent lymphatics and nodes remaining in 14 and 7 patients, respectively. Blue lymphatics and blue nodes were detected in fewer cases. CONCLUSION: Nearly one-third of patients showed crossover between breast and arm draining nodes, which provides insight as to why some patients develop lymphedema symptoms after SLN biopsy. ICG and ISB identify similar numbers of SLNs. As such ICG could substitute for ISB in ARM procedures.

RESUMEN

Obesity and its consequences are a major health concern. There are conflicting reports regarding utilization of preventive health-care services among obese patients. Our objective was to determine whether obese patients receive the same preventive care as normal weight patients. Weighted patient clinic visit data from the National Ambulatory Medical Care Survey (NAMCS) were analyzed for all adult patient visits with height/weight data (N = 866,415,856) from 2005 to 2007. Preventive care practice patterns were compared among different weight groups of normal, obese, and morbidly obese. Obese patients received the least number of preventive exams with a clear gradient present by weight. Obese patients were significantly less likely to receive cancer screening including breast examination (normal weight, reference, obese, odds ratio (OR), 0.8), mammogram (obese OR, 0.7), pap smear (obese OR, 0.7), pelvic exam (obese OR, 0.8), and rectal exam (obese OR, 0.7). The obese population also received less tobacco (obese OR, 0.7) and injury prevention education (obese OR, 0.7), yet significantly more diet, exercise, and weight reduction education. Significant differences in clinic practice patterns relative to normal weight patients were also evident with more physician referral (obese OR, 1.2) and less likely to see physician at the index clinic visit (obese OR, 0.8) and less likely to receive psychotherapy referral (obese OR, 0.6). Significant gaps in preventive care exist for the obese including cancer screening, tobacco cessation and injury prevention counseling, and psychological referral. Although obese patients received more weight-related education, this emphasis may have the consequence of de-emphasizing other needed preventive health measures.

RESUMEN

BACKGROUND: Coronary artery disease is the primary cause of death in the United States, with obesity as a leading preventable risk factor. Previous studies have established the beneficial effect of Roux-en-Y gastric bypass on both weight and cardiac risk factors. Further assessment of cardiac function may be accomplished using B-type natriuretic peptide (BNP), which has demonstrated clinical utility in diagnosing congestive heart failure. This study aimed to assess changes in BNP after intentional weight loss through gastric bypass surgery. METHODS: Plasma volume, weight, and BNP were measured preoperatively and at 3, 6, and 12 months postoperatively for 101 consecutive patients undergoing laparoscopic gastric bypass surgery by a single surgeon in an academic medical setting. Outcomes were compared by matched t-test. Multivariable linear regression and Pearson's correlation were used to examine predictors of pro-B-type natriuretic peptide (NT-proBNP) concentration. RESULTS: The concentration of BNP increased significantly from a mean preoperative level of 50.5 ng/l to postoperative levels of 73.9 ng/l at 3 months (P=0.013), 74.3 ng/l at 6 months (P<0.001), and 156.3 ng/l at 12 months (P<0.001). In addition, excess weight loss was the only statistically significant predictor of increased BNP concentration (odds ratio, 1.483; P<0.05). CONCLUSION: Gastric bypass leads to significant excess weight loss and surprisingly increased BNP concentrations. Correlation of BNP increase with weight loss suggests an additional novel mechanism for surgically induced weight loss.
