Background: The aim of this study was to evaluate whether elderly patients undergoing elective hepatectomy experience increased morbidity/mortality and whether these outcomes could be mitigated by minimally invasive hepatectomy (MIH).Methods: 15,612 patients from 2014 to 2017 were identified in the Hepatectomy Targeted Procedure Participant Use File of the American College of Surgeons National Surgical Quality Improvement Program. Multivariable logistic regression models were constructed to examine the effect of elderly status (age ≥ 75 years, N = 1769) on outcomes with a subgroup analysis of elderly only patients by open (OH) versus MIH (robotic, laparoscopic, and hybrid, N = 4044). Propensity score matching was conducted comparing the effect of MIH to OH in elderly patients to ensure that results are not the artifact of imbalance in baseline characteristics.Results: Overall, elderly patients had increased risk for 30-day mortality, major morbidity, prolonged length of hospital stay, and discharge to destination other than home. In the elderly subgroup, MIH was associated with decreased major morbidity (OR 0.71, P = 0.031), invasive intervention (OR 0.61, P = 0.032), liver failure (OR 0.15, P = 0.011), bleeding (OR 0.46, P < 0.001), and prolonged length of stay (OR 0.46, P < 0.001). Propensity score-matched analyses successfully matched 4021 pairs of patients treated by MIH vs. OH, and logistic regression analyses on this matched sample found that MIH was associated with decreased major complications (OR 0.69, P = 0.023), liver failure (OR 0.14, P = 0.010), bile leak (OR 0.46, P = 0.009), bleeding requiring transfusion (OR 0.46, P < 0.001), prolonged length of stay (OR 0.46, P < 0.001), and discharge to destination other than home (OR 0.691, P = 0.035) compared to OH.Conclusion: MIH is associated with decreased risk of major morbidity, liver failure, bile leak, bleeding, prolonged length of stay, and discharge to destination other than home among elderly patients in this retrospective study. However, MIH in elderly patients does not protect against postoperative mortality. [ABSTRACT FROM AUTHOR]

Gastric adenocarcinoma lymph node retrieval during gastrectomy and survival differ significantly between Asian and Western studies. It is unclear whether such disparities are the result of surgical technique, patient population, or other factors. In this observational study, we aimed to determine whether lymph node retrieval and outcomes differ between White, Black, and Asian American patients undergoing gastrectomy for adenocarcinoma. 47,217 cases of gastric resection for gastric adenocarcinoma and its subtypes were identified in the National Cancer Data Base (2000–2015). Differences in demographics, lymph node retrieval, operative outcomes, and survival were compared by self-reported race (White, Black, and Asian). Asians had greater median lymph node retrieval (17) compared to White (15) and Black (16) patients, P < 0.001. Lymph node ratio was lowest in Asian (0.03) compared to White (0.05) and Black (0.09) patients, P < 0.001. Postoperative mortality was lowest in Asian patients on multivariable analysis (90-day mortality adjusted odds ratio of 0.54, P < 0.001). Median survival was not yet reached for Asian patients but was 39.5 months for White and 43.0 months for Black patients (P < 0.001). Differences in survival by race persisted on multivariable analysis (Asian adjusted hazard ratio was 0.64, 95% CI: 0.59–0.70, P < 0.001). Asian-American patients with gastric cancer undergoing gastrectomy have greater lymph node retrieval, decreased lymph node ratio, decreased postoperative mortality, and increased long-term survival compared to White or Black Americans. Data suggest factors other than surgical technique and oncologic care may be responsible for gastric adenocarcinoma outcome differences seen between Asian and Western studies. [ABSTRACT FROM AUTHOR]

Background: Insurance status has been associated with disparities in stage at cancer diagnosis. We examined how Medicaid expansion (ME) impacted diagnoses, surgical treatment, use of neoadjuvant therapies (NCRT), and outcomes for Stage II and III rectal cancer., Study Design: We used 2010-2017 American College of Surgeons National Cancer Database (NCDB) to identify patients ages 18-65, with Medicaid as primary form of payment, and were diagnosed with Stage II or III rectal cancer. Patients were stratified based on Census bureau division's ME adoption rates of High, Medium, Low. Overall trends were examined, and patient characteristics and outcomes were compared before and after ME date of 1/1/2014., Results: Over 8 years of NCDB data examined, there was an increasing trend of Stage II and III rectal cancer diagnoses, surgical resection, and use of NCRT for Medicaid patients. We observed an increase in age, proportion of White Medicaid patients in Low ME divisions, and proportion of fourth income quartile patients in High ME divisions. Univariate analysis showed decreased use of open surgery for all 3 categories after ME, but adjusted odds ratios (aOR) were not significant based on multivariate analysis. NCRT utilization increased after ME for all 3 ME adoption categories and aOR significantly increased for Low and High ME divisions. ME significantly decreased 90-day mortality., Conclusions: Medicaid expansion had important impacts on increasing Stage II and III rectal cancer diagnoses, use of NCRT, and decreased 90-day mortality for patients with Medicaid. Our study supports increasing health insurance coverage to improve Medicaid patient outcomes in rectal cancer care., (Copyright © 2022 by the American College of Surgeons.

Background: Remote appendectomy was linked to increased incidence of Clostridioides difficile infection (CDI). We evaluated the effect of absence of vermiform appendix and/or gallbladder on recurrence rate and severity of CDI., Methods: We assessed a systemwide patient cohort diagnosed with initial CDI in 2014 (n = 250). The primary outcome was recurrence., Results: Appendix and gallbladder were absent among 47 and 64 patients, respectively. CDI recurrence rate was similar among patients without and with appendix (24/47, 51.1% versus 90/203 patients, 44.3%; p = 0.404) and similar among patients without and with gallbladder (29/64 patients, 45.3% versus 85/186 patients, 45.7%; p = 0.957). Mortality was similar between appendectomy versus appendix in situ patients (3/47, 6.4% versus 9/203, 4.4%; p = 0.573), but higher mortality rate was seen among those without gallbladder (7/64 patients with prior cholecystectomy, 10.9% versus 5/186 patients with intact gallbladder, 2.7%; p = 0.008)., Conclusion: Clostridioides difficile recurrence rate is not affected by remote appendectomy or cholecystectomy. Patients with prior cholecystectomy experience higher mortality rates associated with their CDI., Competing Interests: Declaration of competing interest Primary author – Jan Franko – declared on behalf of all authors that no one have any conflict of interest, financial or otherwise, associated with the submitted paper., (Copyright © 2019 Elsevier Inc.
