RESUMEN
Background: According to Dutch guidelines, locally excised, low-risk, pT1 or ypT0-1 rectal cancer should not necessarily be followed by completion total mesorectal excision (cTME) in contrast to rectal cancers with higher T stages or unfavorable features. This study evaluated cTME after local excision at a national level with possible determinants for decision-making. Methods: All patients in the Dutch Colorectal Audit (DCRA) who underwent local excision of rectal cancer between 2012 and 2015 were included. Guideline adherence for performing cTME was determined with univariate and multivariate analyses to identify factors related to noncompliance. Results: According to the guidelines, of 530 included patients, cTME was indicated in 283 (53%), and among those, was performed in 82 (29%). Guideline adherence for performing cTME improved significantly (P<.001), from 10% in 2012 to 44% in 2015. Lower Charlson comorbidity index in patients with high-risk pT1 rectal cancer and younger patients (aged 61-70 years vs ≥80 years) with pT≥2 rectal cancer were associated with increased performance of cTME (odds ratio [OR], 13.50; 95% CI, 1.39-131.32, and OR, 6.25; 95% CI, 1.83-21.31, respectively). Conclusions: In this population-based study from the Netherlands, only a minority of patients underwent cTME after local excision of rectal cancer with pathologic features indicating the need for further treatment according to the guidelines. Although the percentage of patients undergoing cTME increased over time, the study indicated a tendency toward rectal-preserving treatment with potential oncologic risks.

Background: It is unclear whether emergency weekend colon and rectal cancer surgery are associated with worse outcomes (ie, weekend effect) because previous studies mostly used administrative data, which may insufficiently adjust for case-mix. Materials and Methods: Prospectively collected data from the 2012-2015 Dutch ColoRectal Audit (n=5,224) was used to examine differences in 30-day mortality and severe complication and failure-to-rescue rates for emergency weekend (Saturday and Sunday) versus Monday surgery, stratified for colon and rectal cancer. Analyses were adjusted for age, sex, body mass index, Charlson comorbidity index, American Society of Anesthesiologists classification score, tumor stage, presence of metastasis, preoperative complication, additional resection for metastasis or locally advanced tumor, location primary colon tumor, type of rectal surgery (lower anterior resection or abdominal perineal resection), and type of neoadjuvant therapy (short-course radiotherapy or chemoradiotherapy). Results: A total of 5,052 patients undergoing colon cancer surgery and 172 undergoing rectal cancer surgery were included. Patients undergoing colon or rectal cancer surgery during weekends had significantly more preoperative tumor complications compared with those undergoing surgery on a weekday. Additionally, differences in year of surgery and location of primary tumor were found for colon cancer surgery. Emergency colon cancer surgery during the weekend was associated with increased 30-day mortality (odds ratio [OR], 1.66; 95% CI, 1.10-2.50) and severe complications (OR, 1.29; 95% CI, 1.03-1.63) compared with surgery on Monday. Estimates for emergency weekend rectal cancer surgery were similar but not statistically significant, likely explained by small numbers. Conclusions: Weekend emergency colon cancer surgery was associated with higher mortality and severe complication rates. More research is needed to understand which factors explain and contribute to these differences.

INTRODUCTION: Bariatric surgery aims for optimal patient outcomes, often evaluated through the percentage total weight loss (%TWL). Quality registries employ funnel plots for outcome comparisons between hospitals. However, funnel plots are traditionally used for dichotomous outcomes, requiring %TWL to be dichotomized, potentially limiting feedback quality. This study evaluates whether a funnel plot around the median %TWL has better discriminatory performance than binary funnel plots for achieving at least 20% and 25% TWL. METHODS: All hospitals performing bariatric surgery were included from the Dutch Audit for Treatment of Obesity. A funnel plot around the median was constructed using 5-year %TWL data. Hospitals positioned above the 95% control limit were colored green and those below red. The same hospitals were plotted in the binary funnel plots for 20% and 25% TWL and colored according to their performance in the funnel plot around the median. We explored the hospital's procedural mix in relation to %TWL performance as possible explanatory factors. RESULTS: The median-based funnel plot identified four underperforming and four outperforming hospitals, while only one underperforming and no outperforming hospitals were found with the binary funnel plot for 20% TWL. The 25% TWL binary funnel plot identified two underperforming and three outperforming hospitals. The proportion of sleeve gastrectomies performed per hospital may explain part of these results as it was negatively associated with median %TWL (ß = - 0.09, 95% confidence interval [- 0.13 to - 0.04]). CONCLUSION: The funnel plot around the median discriminated better between hospitals with significantly worse and better performance than funnel plots for dichotomized %TWL outcomes.
