Are Geographical Health Accessibility and Socioeconomic Deprivation Associated with Outcomes Following Bariatric Surgery? A Retrospective Study in a High-Volume Referral Bariatric Surgical Center.

PURPOSE: Few studies have evaluated the association between non-clinical determinants (socioeconomic status and geographic accessibility to healthcare) and the outcomes of bariatric surgery, with conflicting results. This study aimed to evaluate this association. METHODS: The medical records of 1599 consecutive patients who underwent either laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy between June 2005 and December 2017 were retrieved. All relevant data, including patient characteristics, biometric values before and after surgery, related medical problems, surgical history, medications, and habitus, for each patient were prospectively collected in a database. Logistic regressions were used to assess the influence of non-clinical determinants on surgical indications and complications. Multilevel linear or logistic regression was used to evaluate the influence of non-clinical determinants on long-term %TWL and the probability to achieve adequate weight loss (defined as a %TWL > 20% at 12 months). RESULTS: Analysis of the 1599 medical records revealed that most geographically isolated patients were more likely to have undergone laparoscopic Roux-en-Y gastric bypass (odds ratio: 0.97; 95% confidence interval: 0.94 to 0.99; P = 0.018) and had a greater likelihood of adequate weight loss (ß: 0.03; 95% CI: 0.01 to 0.05; P = 0.021). Conversely, socioeconomic status (measured by the European Deprivation Index) did not affect outcomes following bariatric surgery. CONCLUSION: Geographical health isolation is associated with a higher probability to achieve adequate weight loss after 1 year of follow-up, while neither health isolation nor socioeconomic deprivation is associated with post-operative mortality and morbidity. This results suggests that bariatric surgery is a safe and effective tool for weight loss despite socioeconomic deprivation.

Influence of non-clinical factors on restorative rectal cancer surgery: An analysis of four specialized population-based digestive cancer registries in France.

BACKGROUND: This study aims to measure the association between deprivation, health care accessibility and health care system with the likelihood of receiving non-restorative rectal cancer surgery (NRRCS). METHODS: All adult patients who had rectal resection for invasive adenocarcinoma diagnosed between 2007 and 2016 in four French specialised cancer registries were included. A multilevel logistic regression with random effect was used to assess the link between patient and health care structure characteristics on the probability of NRRCS. RESULTS: 2997 patients underwent rectal cancer resection in 68 health care structures: 708 (23.63%) had NRRCS. The likelihood of receiving NRCCS was associated with patients' characteristics (97%): age, sub peritoneal rectal tumors, neoadjuvant therapy, residual tumour and stage III . There was no impact of European Deprivation Index or remoteness on NRRCS. Inter-health care structure variability was modest (3%), of which 50% was explained by the high group volume of colorectal procedures and the type of health care structure which were associated with less NRRCS (p<0.01). CONCLUSION: There is an influence of operating volume and type of structure on the probability of NRRCS, but it has truly little importance in explaining differences in performances. The probability of NRRCS is mainly affected by clinical determinant.

Permanent stoma after sphincter preservation for rectal cancer. A situation that occurs more often than you might think.

Objectives: This study aimed: (i) to assess the cumulative incidence of permanent stoma (PS) after sphincter-preserving surgery (SPS) for rectal cancer (RC): (ii) to analyze associated risk factors for primary and secondary PS; and (iii) to compare the long-term survival of patients according to the stoma state. Methods: We conducted a retrospective single-center cohort study based on a prospectively maintained database of SRC patients undergoing SPS from January 2007 to December 2017. Incidence of both primary (no reversal of defunctioning stoma) and secondary (created after closure of defunctioning stoma) PS were investigated. Associations between potential risk factors and PS were analyzed using a logistic regression model. Cumulative survival curve was drawn by Kaplan-Meier method. Results: Of the 257 eligible patients, 43 patients (16.7%) had a PS (16 primary PS and 27 secondary PS) after a median follow-up of 4.8 years. In multivariate analysis, the independent risk factors for primary PS were severe post-operative complications (OR 3.66; 95% CI, 1.19-11.20, p=0.022), and old age (OR 1.11; 95% CI 1.04-1.18, p=0.001) and those for secondary PS were local recurrence (OR 38.07; 95% CI 11.07-130.9, p<0.0001), anastomotic leakage (OR 7.01; 95% CI, 2.23-22.04, p=0.009), and severe post-operative complications (OR 3.67; 95% CI, 1.22-11.04, p=0.02), respectively. Both overall survival (OS) and disease-free survival (DFS) were significantly lower in patients with a PS compared with patients with SPS (p < 0.01). Conclusions: This present study suggests that one out of 6 patients has a PS, 5 years after rectal resection with SPS for SRC.
