Uncommon Sociodemographic Factors Are Associated With Racial Disparities in Length of Stay Following Oncologic Elective Colectomy.

INTRODUCTION: Although outcome disparities by race have been identified in colorectal cancer, these patterns are challenging to explain using variables that are commonly available in databases. In a single institution serving a diverse community, length of stay (LOS) varies by race following elective oncologic colectomy. We investigated previously unexplored variables that may explain the relationship between race and LOS following elective resection of colorectal neoplasms. METHODS: Retrospective, single institution cohort study from January 2015 to December 2020 for adult patients undergoing elective colorectal cancer resections. Baseline demographic variables and intraoperative factors were analyzed for changes in LOS following elective colorectal resection. Additional retrospective chart review was carried out to determine household member composition and distance from home to hospital. Bivariate analysis was conducted to determine which variables should be included in multivariable analyses. All analyses were conducted using SAS Academic. RESULTS: Most patients (n = 383) were Asian (40%), Black (12%), or Hispanic (26%). Race and LOS were associated with age (P = 0.001 and P < 0.001 for race and LOS, respectively), American Society of Anesthesiologists class (P = 0.004 and P < 0.001), enhanced recovery after surgery protocols (P = 0.006 and P < 0.001), household members (P = 0.009 and P = 0.002), and discharge disposition (P = 0.049 and P < 0.001). In multivariable analysis, household members (P = 0.021) independently remained associated with LOS after controlling for race (P = 0.008) and discharge disposition (P < 0.001). CONCLUSIONS: Household member composition varies with LOS, suggesting that level of support at home may influence decisions regarding discharge disposition, which lead to differences in LOS.

Transanal total mesorectal excision achieves equivalent oncologic resection compared to laparoscopic approach, but with functional consequences.

BACKGROUND: This study compared transanal total mesorectal excision (taTME) to laparoscopic total mesorectal excision (laTME) for the treatment of low rectal cancer. Adequacy of oncologic resection as well as postoperative outcomes were analyzed. METHODS: We retrospectively reviewed all proctectomy for low rectal cancer by a single surgeon at our institution from January 2014 to September 2019. RESULTS: There were 20 taTME and 30 laTME patients. TaTME patients had more distal tumors with no difference in pathologic resection margins or frequency of positive distal margin. Operative times were longer for taTME, but there were no differences in short-term outcomes or complications. TaTME patients had a higher rate of postoperative fecal incontinence. CONCLUSION: TaTME may be a good option for the most distal tumors, when distal margins may be compromised. TaTME provides equivalent oncologic resection, but there is a higher incidence of postoperative fecal incontinence.
