Nationwide Association of Surgical Performance of Minimally Invasive Esophagectomy With Patient Outcomes.

Importance: Suboptimal surgical performance is hypothesized to be associated with less favorable patient outcomes in minimally invasive esophagectomy (MIE). Establishing this association may lead to programs that promote better surgical performance of MIE and improve patient outcomes. Objective: To investigate associations between surgical performance and postoperative outcomes after MIE. Design, Setting, and Participants: In this nationwide cohort study of 15 Dutch hospitals that perform more than 20 MIEs per year, 7 masked expert MIE surgeons assessed surgical performance using videos and a previously developed and validated competency assessment tool (CAT). Each hospital submitted 2 representative videos of MIEs performed between November 4, 2021, and September 13, 2022. Patients registered in the Dutch Upper Gastrointestinal Cancer Audit between January 1, 2020, and December 31, 2021, were included to examine patient outcomes. Exposure: Hospitals were divided into quartiles based on their MIE-CAT performance score. Outcomes were compared between highest (top 25%) and lowest (bottom 25%) performing quartiles. Transthoracic MIE with gastric tube reconstruction. Main Outcome and Measure: The primary outcome was severe postoperative complications (Clavien-Dindo ≥3) within 30 days after surgery. Multilevel logistic regression, with clustering of patients within hospitals, was used to analyze associations between performance and outcomes. Results: In total, 30 videos and 970 patients (mean [SD] age, 66.6 [9.1] years; 719 men [74.1%]) were included. The mean (SD) MIE-CAT score was 113.6 (5.5) in the highest performance quartile vs 94.1 (5.9) in the lowest. Severe postoperative complications occurred in 18.7% (41 of 219) of patients in the highest performance quartile vs 39.2% (40 of 102) in the lowest (risk ratio [RR], 0.50; 95% CI, 0.24-0.99). The highest vs the lowest performance quartile showed lower rates of conversions (1.8% vs 8.9%; RR, 0.21; 95% CI, 0.21-0.21), intraoperative complications (2.7% vs 7.8%; RR, 0.21; 95% CI, 0.04-0.94), and overall postoperative complications (46.1% vs 65.7%; RR, 0.54; 95% CI, 0.24-0.96). The R0 resection rate (96.8% vs 94.2%; RR, 1.03; 95% CI, 0.97-1.05) and lymph node yield (mean [SD], 38.9 [14.7] vs 26.2 [9.0]; RR, 3.20; 95% CI, 0.27-3.21) increased with oncologic-specific performance (eg, hiatus dissection, lymph node dissection). In addition, a high anastomotic phase score was associated with a lower anastomotic leakage rate (4.6% vs 17.7%; RR, 0.14; 95% CI, 0.06-0.31). Conclusions and Relevance: These findings suggest that better surgical performance is associated with fewer perioperative complications for patients with esophageal cancer on a national level. If surgical performance of MIE can be improved with MIE-CAT implementation, substantially better patient outcomes may be achievable.

The effect of prehabilitation on long-term survival and hospital admissions in older patients undergoing elective colorectal cancer surgery.

INTRODUCTION: There is a growing body of evidence for a beneficial effect of prehabilitation on short-term outcomes after colorectal cancer (CRC) surgery in older patients. However, long-term effects on survival or hospital admissions have not been investigated. This study reports these long-term outcomes from a previously published observational cohort study. METHODS: We compared patients ≥75 years who received elective CRC surgery in Reinier de Graaf Hospital before (2010-2013: standard care) and after implementation of a multimodal prehabilitation program (2014-2015; prehabilitation). With a six-year follow-up period, we analyzed survival using the Kaplan-Meier method and the occurrence of one or more hospital admissions using logistic regression analyses. RESULTS: Overall, 137 patients were included in the standard care group and 86 patients in the prehabilitation group. There were no differences in patients, tumor and treatment characteristics. After six years, 51.1% in the standard care group and 59.3% in the prehabilitation group (p = 0.167) were still alive. When corrected for confounders in the prehabilitation group less patients had one or more hospital admissions during follow-up (odds ratio (OR) 0.43 (95% CI 0.24-0.77). CONCLUSIONS: Unfortunately these limited historical cohorts did not allow for strong conclusions concerning long-time survival. However, after prehabilitation less patients had hospital admissions during follow up. Hopefully, this first study into the long-term effects of multimodal prehabilitation will trigger more future research.

The Assessment of Burden of ColoRectal Cancer (ABCRC)-tool; a validity and reliability study.

INTRODUCTION: Follow-up care after treatment for colorectal cancer (CRC) is increasingly focused on health-related quality of life (HRQoL) and functional outcomes. The Assessment of Burden of ColoRectal Cancer (ABCRC)-tool is developed to measure these outcomes and support patient-oriented care. The tool comprises items assessing burden of disease and lifestyle parameters. It consists of a generic module combined with one of the three CRC specific modules. The objective of this study is to assess the construct validity and reliability of the items of the ABCRC-tool. METHODS: Patients who were receiving follow-up care after surgical CRC treatment were invited to complete the ABCRC-tool together with other validated patient-reported outcome measures (PROMs). Construct validity was assessed by testing expected correlations between items of the ABCRC-tool and domains of other PROMs and by examining predefined hypotheses regarding differences in subgroups of patients. Patients completed the ABCRC-tool twice, with 8 days apart, to evaluate its reliability. RESULTS: In total, 177 patients participated (64% male) with a mean age of 67 years (range 33-88). The colon, rectum and stoma module were completed by subsequently 89, 53 and 35 patients. Most items correlated as expected with anticipated domains of the EORTC QLQ-C30 or EORTC QLQ-CR29 (all p-values <0.05). Furthermore, the ABCRC-tool could discriminate between subgroups of patients. The intraclass correlation coefficient (ICC) was good (>0.70) for most items, indicating good reliability. CONCLUSION: The ABCRC-tool is a valid and reliable instrument that is ready for use in a clinical setting to support personalized follow-up care after CRC treatment.

Prognostic value of Mandard score and nodal status for recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma.

BACKGROUND: This study evaluated the association of pathological tumour response (tumour regression grade, TRG) and a novel scoring system, combining both TRG and nodal status (TRG-ypN score; TRG1-ypN0, TRG>1-ypN0, TRG1-ypN+ and TRG>1-ypN+), with recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma. METHODS: This Dutch nationwide cohort study included patients treated with neoadjuvant chemoradiotherapy followed by oesophagectomy for distal oesophageal or gastro-oesophageal junctional adenocarcinoma between 2007 and 2016. The primary endpoint was the association of Mandard score and TRG-ypN score with recurrence patterns (rate, location, and time to recurrence). The secondary endpoint was overall survival. RESULTS: Among 2746 inclusions, recurrence rates increased with higher Mandard scores (TRG1 30.6%, TRG2 44.9%, TRG3 52.9%, TRG4 61.4%, TRG5 58.2%; P < 0.001). Among patients with recurrent disease, the distribution (locoregional versus distant) was the same for the different TRG groups. Patients with TRG1 developed more brain recurrences (17.7 versus 9.8%; P = 0.001) and had a longer mean overall survival (44 versus 35 months; P < 0.001) than those with TRG>1. The TRG>1-ypN+ group had the highest recurrence rate (64.9%) and worst overall survival (mean 27 months). Compared with the TRG>1-ypN0 group, patients with TRG1-ypN+ had a higher risk of recurrence (51.9 versus 39.6%; P < 0.001) and worse mean overall survival (33 versus 41 months; P < 0.001). CONCLUSION: Improved tumour response to neoadjuvant therapy was associated with lower recurrence rates and higher overall survival rates. Among patients with recurrent disease, TRG1 was associated with a higher incidence of brain recurrence than TRG>1. Residual nodal disease influenced prognosis more negatively than residual disease at the primary tumour site.

The prognostic value of a geriatric risk score for older patients undergoing emergency surgery of colorectal cancer: A retrospective cohort study.

INTRODUCTION: Emergency surgery of colorectal cancer is associated with high mortality rates in older patients. We investigated whether information on four geriatric domains has prognostic value for 30-day mortality and postoperative morbidity including severe complications. MATERIALS AND METHODS: All consecutive patients aged 70 years or older who underwent emergency colorectal cancer surgery in six Dutch hospitals (2014-2017) were studied. Presence of geriatric risk factors was scored prior to surgery as either 0 (risk absent) or 1 (risk present) in each of four geriatric domains and summed up to calculate a sumscore with a value between 0 and 4. In addition, we separately investigated the use of a mobility aid. Primary outcome was 30-day mortality. Secondary outcomes were any postoperative complications and severe complications. Multivariable logistic regression model was used to evaluate the sumscore and outcomes. RESULTS: Two hundred seven patients were included. Median age was 79.4 years. One hundred seventy-five patients (76%) presented with obstruction, 22 (11%) with a perforation, and 17 (8%) with severe anemia. Mortality rates were 2.9%, 13.6%, and 29.6% for patients with a sumscore of 0, 1-2, and 3-4 respectively, with odds ratio (OR) 4.8 [95% confidence interval (CI) 1.03-22.95] and OR 10.6 [95% CI 1.99-56.34] for a sumscore of 1-2 and 3-4 respectively. Use of a mobility aid was associated with increased mortality OR 8.0 [95% CI 2.74-23.43] and severe complications OR 2.31 [95% CI 1.17-4.55]. DISCUSSION: This geriatric sumscore and the use of a mobility aid have strong association with 30-day mortality after emergency surgery of colorectal cancer. This could provide better insight into surgical risk and help select high-risk patients for alternative strategies.

Evolution of surgical approach to rectal cancer resection: A multinational registry assessment.

PURPOSE: Surgical approach to rectal cancer has evolved in recent decades, with introduction of minimally invasive surgery (MIS) techniques and local excision. Since implementation might differ internationally, this study is aimed at evaluating trends in surgical approach to rectal cancer across different countries over the last 10 years and to gain insight into patient, tumour and treatment characteristics. METHODS: Pseudo-anonymised data of patients undergoing resection for rectal cancer between 2010 and 2019 were extracted from clinical audits in the Netherlands (NL), Sweden (SE), England-Wales (EW) and Australia-New Zealand (AZ). RESULTS: Ninety-nine thousand five hundred ninety-seven patients were included (38,413 open, 55,155 MIS and 5416 local excision). An overall increase in MIS was observed from 29.9% in 2010 to 72.1% in 2019, with decreasing conversion rates (17.5-9.0%). The MIS proportion was highly variable between countries in the period 2010-2014 (54.4% NL, 45.3% EW, 39.8% AZ, 14.1% SE, P < 0.001), but variation reduced over time (2015-2019 78.8% NL, 66.3% EW, 64.3% AZ, 53.2% SE, P < 0.001). The proportion of local excision for the two periods was highly variable between countries: 4.7% and 11.8% in NL, 3.9% and 7.4% in EW, 4.7% and 4.6% in AZ, 6.0% and 2.9% in SE. CONCLUSIONS: Application and speed of implementation of MIS were highly variable between countries, but each registry demonstrated a significant increase over time. Local excision revealed inconsistent trends over time.

Determinants of Physical Activity among Patients with Colorectal Cancer: From Diagnosis to Five Years after Diagnosis.

INTRODUCTION: Physical activity (PA) is associated with higher quality of life and probably better prognosis among colorectal cancer (CRC) patients. This study focuses on determinants of PA among CRC patients from diagnosis until five years post-diagnosis. METHODS: Sociodemographic and disease-related factors of participants of two large CRC cohort studies were combined. Moderate-to-vigorous PA during sport and leisure time (MVPA-SL) was measured at diagnosis (T0) and six, twelve, twenty-four, and sixty (T6 to T60) months post-diagnosis, using the SQUASH questionnaire. Mixed-effects models were performed to identify sociodemographic and disease-related determinants of MVPA-SL, separately for stage I-III colon (CC), stage I-III rectal cancer (RC), and stage IV CRC (T0 and T6 only). Associations were defined as consistently present when significant at ≥4 timepoints for the stage I-III subsets. MVPA-SL levels were compared with an age- and sex-matched sample of the general Dutch population. RESULTS: In total, 2905 CC, 1459 RC and 436 stage IV CRC patients were included. Patients with higher fatigue scores, and women compared to men had consistently lower MVPA-SL levels over time, regardless of tumor type and stage. At T6, having a stoma was significantly associated with lower MVPA-SL among stage I-III RC patients. Systemic therapy and radiotherapy were not significantly associated with MVPA-SL changes at T6. Compared to the general population, MVPA-SL levels of CRC patients were lower at all timepoints, most notably at T6. CONCLUSIONS: Female sex and higher fatigue scores were consistent determinants of lower MVPA-SL levels among all CRC patients, and MVPA-SL levels were lowest at six months post-diagnosis. Our results can inform the design of intervention studies aimed at improving PA, and guide healthcare professionals in optimizing individualized support.

2 days versus 5 days of Postoperative Antibiotics for Complex Appendicitis: Cost Analysis of a Randomized, Non-inferiority Trial.

OBJECTIVE: To compare costs for 2 days versus 5 days of postoperative antibiotics within the Antibiotics following aPPendectomy In Complex appendicitis (APPIC) trial.Summary Background Data:Recent studies suggest that restrictive antibiotic use leads to a significant reduction in hospital stay without compromising patient safety. Its potential effect on societal costs remains underexplored. METHODS: This was a pragmatic, open-label, multicenter clinical trial powered for non-inferiority. Patients with complex appendicitis (age ≥ 8 y) were randomly allocated to 2 days or 5 days of intravenous antibiotics after appendectomy. Patient inclusion lasted from June 2017 to June 2021 in 15 Dutch hospitals. Final follow-up was on September 1, 2021. The primary trial endpoint was a composite endpoint of infectious complications and mortality within 90 days. In the present study, main outcome measures were overall societal costs (comprising direct healthcare costs and costs related to productivity loss) and cost-effectiveness. Direct healthcare costs were recorded based on data in the electronic patient files, complemented by a telephone follow-up at 90 days. In addition, data on loss of productivity were acquired through the validated Productivity-Cost-Questionnaire at four weeks after surgery. Cost estimates were based on prices for the year 2019. RESULTS: In total, 1005 patients were evaluated in the Intention-to-Treat analysis: 502 patients allocated to the 2-day group and 503 to the 5-day group. The mean difference in overall societal costs was - € 625 (95% confidence interval - € 958 to - € 278) to the advantage of the 2-day group. This difference was largely explained by reduced hospital stay. Productivity losses were similar between the study groups. Restricting postoperative antibiotics to two days was cost-effective, with estimated cost savings of € 31,117 per additional infectious complication. CONCLUSIONS: 2 days of postoperative antibiotics for complex appendicitis results in a statistically significant and relevant cost reduction, as compared with 5 days. Findings apply to laparoscopic appendectomy in a well-resourced healthcare setting. TRIAL REGISTRATION: Trialregister.nl number NL5946.

Uptake of robot-assisted colon cancer surgery in the Netherlands.

BACKGROUND: The robot-assisted approach is now often used for rectal cancer surgery, but its use in colon cancer surgery is less well defined. This study aims to compare the outcomes of robotic-assisted colon cancer surgery to conventional laparoscopy in the Netherlands. METHODS: Data on all patients who underwent surgery for colon cancer from 2018 to 2020 were collected from the Dutch Colorectal Audit. All complications, readmissions, and deaths within 90 days after surgery were recorded along with conversion rate, margin and harvested nodes. Groups were stratified according to the robot-assisted and laparoscopic approach. RESULTS: In total, 18,886 patients were included in the analyses. The operative approach was open in 15.2%, laparoscopic in 78.9% and robot-assisted in 5.9%. The proportion of robot-assisted surgery increased from 4.7% in 2018 to 6.9% in 2020. There were no notable differences in outcomes between the robot-assisted and laparoscopic approach for Elective cT1-3M0 right, left, and sigmoid colectomy. Only conversion rate was consistently lower in the robotic group. (4.6% versus 8.8%, 4.6% versus 11.6%, and 1.6 versus 5.9%, respectively). CONCLUSIONS: This nationwide study on surgery for colon cancer shows there is a gradual but slow adoption of robotic surgery for colon cancer up to 6.9% in 2020. When comparing the outcomes of right, left, and sigmoid colectomy, clinical outcomes were similar between the robotic and laparoscopic approach. However, conversion rate is consistently lower in the robotic procedures.

Esophageal cancer patients' need for information and support in making a treatment decision between standard surgery and active surveillance.

BACKGROUND: This study explores patients' need for information and support in deciding on esophageal cancer treatment, when experimental active surveillance and standard surgery are both feasible. METHODS: This psychological companion study was conducted alongside the Dutch SANO-trial (Surgery As Needed for Oesophageal cancer). In-depth interviews and questionnaires were used to collect data from patients who declined participation in the trial because they had a strong preference for either active surveillance (n = 20) or standard surgery (n = 20). Data were analyzed using both qualitative and quantitative techniques. RESULTS: Patients prefer to receive information directly from their doctors and predominantly rely on this information to make a treatment decision. Other information resources are largely used to confirm their treatment decision. Patients highly value support from their loved ones and appreciate emphatic doctors to actively involve them in the decision-making process. Overall, patients' needs for information and support during decision-making were met. CONCLUSIONS: The importance of shared decision-making and the role doctors have in this process is underlined. The role of doctors is essential at the initial phase of decision-making: Once patients seem to have formed their treatment preference for either active surveillance or surgery, the influence of external resources (including doctors) may be limited.

Nationwide practice in CT-based preoperative staging of colon cancer and concordance with definitive pathology.

INTRODUCTION: In an era of exploring patient-tailored treatment options for colon cancer, preoperative staging is increasingly important. This study aimed to evaluate completeness and reliability of CT-based preoperative locoregional colon cancer staging in Dutch hospitals. MATERIALS AND METHODS: Patients who underwent elective oncological resection of colon cancer without neoadjuvant treatment in 77 Dutch hospitals were evaluated between 2011 and 2021. Completeness of T-stage was calculated for individual hospitals and stratified based on a 60% cut-off. Concordance between routine CT-based preoperative locoregional staging (cTN) and definitive pathological staging (pTN) was examined. RESULTS: A total of 59,558 patients were included with an average completeness of 43.4% and 53.4% for T and N-stage, respectively. Completeness of T-stage improved from 4.9% in 2011-2014 to 74.4% in 2019-2021. Median completeness for individual hospitals was 53.9% (IQR 27.3-80.5%) and were not significantly different between low and high-volume hospitals. Sensitivity and specificity for T3-4 tumours were relatively low: 75.1% and 76.0%, respectively. cT1-2 tumours were frequently understaged based on a low negative predictive value of 56.8%. Distinction of cT4 and cN2 disease had a high specificity (>95%), but a very low sensitivity (<50%). Positive predictive values of <60% indicated that cT4 and cN1-2 were often overstaged. Completeness and time period did not influence reliability of staging. CONCLUSION: Completeness of locoregional staging of colon cancer improved during recent years and varied between hospitals independently from case volume. Discriminating cT1-2 from cT3-4 tumours resulted in substantial understaging and overstaging, additionally cT4 and cN1-2 were overstaged in >40% of cases.

Surgeon's steering behaviour towards patients to participate in a cluster randomised trial on active surveillance for oesophageal cancer: A qualitative study.

INTRODUCTION: Few studies have been conducted into how physicians use steering behaviour that may persuade patients to choose for a particular treatment, let alone to participate in a randomised trial. The aim of this study is to assess if and how surgeons use steering behaviour in their information provision to patients in their choice to participate in a stepped-wedge cluster randomised trial investigating an organ sparing treatment in (curable) oesophageal cancer (SANO trial). MATERIALS AND METHODS: A qualitative study was performed. Thematic content analysis was applied to audiotaped and transcribed consultations of twenty patients with eight different oncological surgeons in three Dutch hospitals. Patients could choose to participate in a clinical trial in which an experimental treatment of 'active surveillance' (AS) was offered. Patients who did not want to participate underwent standard treatment: neoadjuvant chemoradiotherapy followed by oesophagectomy. RESULTS: Surgeons used various techniques to steer patients towards one of the two options, mostly towards AS. The presentation of pros and cons of treatment options was imbalanced: positive framing of AS was used to steer patients towards the choice for AS, and negative framing of AS to make the choice for surgery more attractive. Further, steering language, i.e. suggestive language, was used, and surgeons seemed to use the timing of the introduction of the different treatment options, to put more focus on one of the treatment options. CONCLUSION: Awareness of steering behaviour can help to guide physicians in more objectively informing patients on participation in future clinical trials.

The impact on health-related quality of a stoma or poor functional outcomes after rectal cancer surgery in Dutch patients: A prospective cohort study.

BACKGROUND: As the survival of patients with rectal cancer has improved in recent decades, more and more patients have to live with the consequences of rectal cancer surgery. An influential factor in long-term Health-related Quality of Life (HRQoL) is the presence of a stoma. This study aimed to better understand the long-term consequences of a stoma and poor functional outcomes. METHODS: Patients who underwent curative surgery for a primary tumor located in the rectosigmoid and rectum between 2013 and 2020 were identified from the nationwide Prospective Dutch Colorectal Cancer (PLCRC) cohort study. Patients received the following questionnaires: EORTC-QLQ-CR29, EORTC-QLQ-C30, and the LARS-score at 12 months, 24 months and 36 months after surgery. RESULTS: A total of 1,170 patients were included of whom 751 (64.2%) had no stoma, 122 (10.4%) had a stoma at primary surgery, 45 (3.8%) had a stoma at secondary surgery and 252 (21.5%) patients that underwent abdominoperineal resection (APR). Of all patients without a stoma, 41.4% reported major low-anterior resection syndrome (LARS). Patients without a stoma reported significantly better HRQoL. Moreover, patients without a stoma significantly reported an overall better HRQoL. CONCLUSION: The presence of a stoma and poor functional outcomes were both associated with reduced HRQoL. Patients with poor functional outcomes, defined as major LARS, reported a similar level of HRQoL compared to patients with a stoma. In addition, the HRQoL after rectal cancer surgery does not change significantly after the first year after surgery.

Practice variation in anastomotic leak after esophagectomy: Unravelling differences in failure to rescue.

INTRODUCTION: Failure to rescue (FTR) is an important outcome measure after esophagectomy and reflects mortality after postoperative complications. Differences in FTR have been associated with hospital resection volume. However, insight into how centers manage complications and achieve their outcomes is lacking. Anastomotic leak (AL) is a main contributor to FTR. This study aimed to assess differences in FTR after AL between centers, and to identify factors that explain these differences. METHODS: TENTACLE - Esophagus is a multicenter, retrospective cohort study, which included 1509 patients with AL after esophagectomy. Differences in FTR were assessed between low-volume (<20 resections), middle-volume (20-60 resections) and high-volume centers (≥60 resections). Mediation analysis was performed using logistic regression, including possible mediators for FTR: case-mix, hospital resources, leak severity and treatment. RESULTS: FTR after AL was 11.7%. After adjustment for confounders, FTR was lower in high-volume vs. low-volume (OR 0.44, 95%CI 0.2-0.8), but not versus middle-volume centers (OR 0.67, 95%CI 0.5-1.0). After mediation analysis, differences in FTR were found to be explained by lower leak severity, lower secondary ICU readmission rate and higher availability of therapeutic modalities in high-volume centers. No statistically significant direct effect of hospital volume was found: high-volume vs. low-volume 0.86 (95%CI 0.4-1.7), high-volume vs. middle-volume OR 0.86 (95%CI 0.5-1.4). CONCLUSION: Lower FTR in high-volume compared with low-volume centers was explained by lower leak severity, less secondary ICU readmissions and higher availability of therapeutic modalities. To reduce FTR after AL, future studies should investigate effective strategies to reduce leak severity and prevent secondary ICU readmission.

Surgical and non-surgical complications after colorectal cancer surgery in older patients; time-trends and age-specific differences.

BACKGROUND: Trends of surgical and non-surgical complications among the old, older and oldest patients after colorectal cancer (CRC) surgery could help to identify the best target outcome to further improve postoperative outcome. MATERIALS AND METHODS: All consecutive patients ≥70 years receiving curative elective CRC resection between 2011 and 2019 in The Netherlands were included. Baseline variables and postoperative complications were prospectively collected by the Dutch ColoRectal audit (DCRA). We assessed surgical and non-surgical complications over time and within age categories (70-74, 75-79 and ≥ 80 years) and determined the impact of age on the risk of both types of complications by using multivariate logistic regression analyses. RESULTS: Overall, 38648 patients with a median age of 76 years were included. Between 2011 and 2019 the proportion of ASA score ≥3 and laparoscopic surgery increased. Non-surgical complications significantly improved between 2011 (21.8%) and 2019 (17.1%) and surgical complications remained constant (from 17.6% to 16.8%). Surgical complications were stable over time for each age group. Non-surgical complications improved in the oldest two age groups. Increasing age was only associated with non-surgical complications (75-79 years; OR 1.17 (95% CI 1.10-1.25), ≥80 years; OR 1.46 (95% CI 1.37-1.55) compared to 70-74 years), not with surgical complications. CONCLUSION: The reduction of postoperative complications in the older CRC population was predominantly driven by a decrease in non-surgical complications. Moreover, increasing age was only associated with non-surgical complications and not with surgical complications. Future care developments should focus on non-surgical complications, especially in patients ≥75 years.

2 days versus 5 days of postoperative antibiotics for complex appendicitis: a pragmatic, open-label, multicentre, non-inferiority randomised trial.

BACKGROUND: The appropriate duration of postoperative antibiotics for complex appendicitis is unclear. The increasing global threat of antimicrobial resistance warrants restrictive antibiotic use, which could also reduce side-effects, length of hospital stay, and costs. METHODS: In this pragmatic, open-label, non-inferiority trial in 15 hospitals in the Netherlands, patients with complex appendicitis (aged ≥8 years) were randomly assigned (1:1) to receive 2 days or 5 days of intravenous antibiotics after appendicectomy. Randomisation was stratified by centre, and treating physicians and patients were not masked to treatment allocation. The primary endpoint was a composite endpoint of infectious complications and mortality within 90 days. The main outcome was the absolute risk difference (95% CI) in the primary endpoint, adjusted for age and severity of appendicitis, with a non-inferiority margin of 7·5%. Outcome assessment was based on electronic patient records and a telephone consultation 90 days after appendicectomy. Efficacy was analysed in the intention-to-treat and per-protocol populations. Safety outcomes were analysed in the intention-to-treat population. This trial was registered with the Netherlands Trial Register, NL5946. FINDINGS: Between April 12, 2017, and June 3, 2021, 13 267 patients were screened and 1066 were randomly assigned, 533 to each group. 31 were excluded from intention-to-treat analysis of the 2-day group and 30 from the 5-day group owing to errors in recruitment or consent. Appendicectomy was done laparoscopically in 955 (95%) of 1005 patients. The telephone follow-up was completed in 664 (66%) of 1005 patients. The primary endpoint occurred in 51 (10%) of 502 patients analysed in the 2-day group and 41 (8%) of 503 patients analysed in the 5-day group (adjusted absolute risk difference 2·0%, 95% CI -1·6 to 5·6). Rates of complications and re-interventions were similar between trial groups. Fewer patients had adverse effects of antibiotics in the 2-day group (45 [9%] of 502 patients) than in the 5-day group (112 [22%] of 503 patients; odds ratio [OR] 0·344, 95% CI 0·237 to 0·498). Re-admission to hospital was more frequent in the 2-day group (58 [12%] of 502 patients) than in the 5-day group (29 [6%] of 503 patients; OR 2·135, 1·342 to 3·396). There were no treatment-related deaths. INTERPRETATION: 2 days of postoperative intravenous antibiotics for complex appendicitis is non-inferior to 5 days in terms of infectious complications and mortality within 90 days, based on a non-inferiority margin of 7·5%. These findings apply to laparoscopic appendicectomy conducted in a well resourced health-care setting. Adopting this strategy will reduce adverse effects of antibiotics and length of hospital stay.

One Decade of Declining Use of Defunctioning Stomas After Rectal Cancer Surgery in the Netherlands: Are We on the Right Track?

BACKGROUND: The beneficial effect of a defunctioning stoma in mitigating the consequences of anastomotic leakage after rectal cancer surgery is still debated. OBJECTIVE: This study aims to reflect on a decade of rectal cancer surgery in terms of stoma construction and anastomotic leakage. DESIGN: Retrospective observational study. SETTING: This study used data from the Dutch Colorectal Audit from 2011 to 2020. PATIENTS: Patients undergoing rectal cancer surgery with a primary anastomosis. MAIN OUTCOME MEASURES: Primary outcome was anastomotic leakage. Secondary outcomes were minor complications, admission to intensive care, length of stay, readmission, and patient death. RESULTS: A total of 13,263 patients were included in this study. A defunctioning stoma was constructed in 7106 patients (53.6%). Patients with a defunctioning stoma were less likely to develop anastomotic leakage (7.9% vs 13.0%), and if anastomotic leakage occurred, fewer patients needed surgical reintervention (37.7% vs 81.1%). An annual decrease in the construction of a defunctioning stoma was seen (69.8% in 2011 vs 51.8% in 2015 vs 29.7% in 2020), accompanied by a 5% increase in anastomotic leakage (9.1% in 2011 vs 14.1% in 2020). A defunctioning stoma was associated with a higher occurrence of minor complications, increased admissions to the intensive care unit, longer length of stay, and more readmissions within 90 days. LIMITATION: This retrospective study is susceptible to confounders by indications, and there could be risk factors for anastomotic leakage and the use of a stoma that were not regarded. CONCLUSIONS: The reduction in defunctioning stomas is paralleled with an increase in anastomotic leakage. However, patients with a defunctioning stoma also showed more minor complications, a prolonged length of stay, more intensive care admissions, and more readmissions. In our opinion, the trade-offs of selective use should be individually considered. See Video Abstract at http://links.lww.com/DCR/C137 . UNA DCADA DISMINUYENDO EL USO DE ESTOMAS DISFUNCIONANTES EN LOS CASOS DE CNCER DE RECTO EN HOLANDA ESTAMOS HACIENDO LO CORRECTO: ANTECEDENTES:Aún se debate el efecto benéfico de la confección de un estoma disfuncionante para limitar las consecuencias de la fuga anastomótica en los casos de cirugía por cáncer de recto.OBJETIVO:Reflexiones sobre una década de cirugía por cáncer de recto en términos de confección de estomas y de fugas anastomóticas.DISEÑO:Estudio retrospectivo y observacional.AJUSTE:El presente estudio utilizó datos de la Auditoría Colorectal Holandesa entre 2011 y 2020.PACIENTES:Todos aquellos intervenidos por cáncer de recto con anastomosis primaria.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue evaluar la fuga anastomótica. Los resultados secundarios fueron las complicaciones menores, la permanencia en cuidados intensivos, la duración de la hospitalización, las rehospitalizaciones y las causas de muerte en los pacientes.RESULTADOS:Un total de 13.263 pacientes fueron incluidos en el presente estudio. Se confeccionó un estoma disfuncionante en 7.106 (53,6%) pacientes. Aquellos portadores de un estoma disfuncionante tenían menos probabilidades de desarrollar una fuga anastomótica (7,9 % frente a 13,0 %) y, si ocurría una fuga anastomótica, menos pacientes necesitaban reintervención quirúrgica (37,7 % frente a 81,1 %). Se observó una disminución anual en la confección de un estoma disfuncionante (69,8 % en 2011 frente a 51,8 % en 2015 frente a 29,7 % en 2020), acompañada de un aumento del 5 % en la fuga anastomótica (9,1 % en 2011 frente a 14,1 % en 2020). Un estoma disfuncionante se asoció con una mayor incidencia de complicaciones menores, permanencia en la unidad de cuidados intensivos, una estadía más prolongada y más rehospitalizaciones dentro de los 90 días.LIMITACIÓN:Estudio retrospectivo susceptible de factores de confusión según las indicaciones, donde podrían no haber sido considerados ciertos factores de riesgo con relación a la fuga anastomótica y a la confección de un estoma disfuncionante.CONCLUSIÓN:La reducción de estomas disfuncionantes es paralela con el aumento de la fuga anastomótica. Sin embargo, los pacientes con un estoma disfuncionante también mostraron más complicaciones menores, una estadía prolongada, más admisiones a cuidados intensivos y más rehospitalizaciones. En nuestra opinión, las ventajas y desventajas del uso selectivo de estomas disfuncionantes deben ser consideradas caso por caso. Consulte Video Resumen en https://links.lww.com/DCR/C137 .
