RESUMO
BACKGROUND: Guidelines are inconclusive on whether contrast-enhanced MRI using gadoxetic acid and diffusion-weighted imaging should be added routinely to CT in the investigation of patients with colorectal liver metastases who are scheduled for curative liver resection or thermal ablation, or both. Although contrast-enhanced MRI is reportedly superior than contrast-enhanced CT in the detection and characterisation of colorectal liver metastases, its effect on clinical patient management is unknown. We aimed to assess the clinical effect of an additional liver contrast-enhanced MRI on local treatment plan in patients with colorectal liver metastases amenable to local treatment, based on contrast-enhanced CT. METHODS: We did an international, multicentre, prospective, incremental diagnostic accuracy trial in 14 liver surgery centres in the Netherlands, Belgium, Norway, and Italy. Participants were aged 18 years or older with histological proof of colorectal cancer, a WHO performance status score of 0-4, and primary or recurrent colorectal liver metastases, who were scheduled for local therapy based on contrast-enhanced CT. All patients had contrast-enhanced CT and liver contrast-enhanced MRI including diffusion-weighted imaging and gadoxetic acid as a contrast agent before undergoing local therapy. The primary outcome was change in the local clinical treatment plan (decided by the individual clinics) on the basis of liver contrast-enhanced MRI findings, analysed in the intention-to-image population. The minimal clinically important difference in the proportion of patients who would have change in their local treatment plan due to an additional liver contrast-enhanced MRI was 10%. This study is closed and registered in the Netherlands Trial Register, NL8039. FINDINGS: Between Dec 17, 2019, and July 31, 2021, 325 patients with colorectal liver metastases were assessed for eligibility. 298 patients were enrolled and included in the intention-to-treat population, including 177 males (59%) and 121 females (41%) with planned local therapy based on contrast-enhanced CT. A change in the local treatment plan based on liver contrast-enhanced MRI findings was observed in 92 (31%; 95% CI 26-36) of 298 patients. Changes were made for 40 patients (13%) requiring more extensive local therapy, 11 patients (4%) requiring less extensive local therapy, and 34 patients (11%) in whom the indication for curative-intent local therapy was revoked, including 26 patients (9%) with too extensive disease and eight patients (3%) with benign lesions on liver contrast-enhanced MRI (confirmed by a median follow-up of 21·0 months [IQR 17·5-24·0]). INTERPRETATION: Liver contrast-enhanced MRI should be considered in all patients scheduled for local treatment for colorectal liver metastases on the basis of contrast-enhanced CT imaging.

BACKGROUND: Patients undergoing major oncological abdominal surgery are prone to postoperative complications, making early recognition crucial. Clinical deterioration is often preceded by changes in vital signs, which are typically measured thrice a day by a nurse. However, intermittent measurements may delay recognizing clinical deterioration. Continuous vital parameter monitoring may lead to earlier recognition and management of complications and reduce nursing workload. OBJECTIVE: To compare vital parameter measurements between ward nurses and a wireless continuous monitoring system (Sensium® wireless patch) and assess whether this patch can detect clinical deterioration earlier in patients with complications in the first postoperative week. METHODS: Vital parameters (heart rate, respiratory rate, and temperature) were collected in patients undergoing an oncological resection of the liver, colorectal, or pancreas. Sensium® patch measurements were compared to nurses' measurements to assess the percentages of discordant measurements. In patients with complications in the first postoperative week, time discrepancies between nurses and Sensium® patch measurements were identified in cases of clinical deterioration (respiratory rate ≥15/min, heart rate ≥100/min, and temperature ≥38°C). RESULTS: Among 227 patients, 22% of the patients experienced complications. Nurse and Sensium® measurements were discrepant in 586/2272 measurements (26%). In 506/586 discrepancies (86%), this was due to the respiratory rate (difference ≥4/min). Compared to nurses, the Sensium® patch detected an elevated respiratory rate 14 h earlier and heart rate 2 h earlier within complications in the first postoperative week. For temperature, no difference was observed. CONCLUSION: Continuous monitoring with the Sensium® wireless patch holds promise for earlier recognition of complications in patients who underwent major oncological abdominal surgery.

BACKGROUND: In colorectal liver metastases (CRLM) patients, combination of liver resection and ablation permit a more parenchymal-sparing approach. This study assessed trends in use of combined resection and ablation, outcomes, and overall survival (OS). METHODS: This population-based study included all CRLM patients who underwent liver resection between 2014 and 2022. To assess OS, data was linked to two databases containing date of death for patients treated between 2014 and 2018. Hospital variation in the use of combined minor liver resection and ablation versus major liver resection alone in patients with 2-3 CRLM and ≤3 cm was assessed. Propensity score matching (PSM) was applied to evaluate outcomes. RESULTS: This study included 3593 patients, of whom 1336 (37.2%) underwent combined resection and ablation. Combined resection increased from 31.7% in 2014 to 47.9% in 2022. Significant hospital variation (range 5.9-53.8%) was observed in the use of combined minor liver resection and ablation. PSM resulted in 1005 patients in each group. Major morbidity was not different (11.6% vs. 5%, P = 1.00). Liver failure occurred less often after combined resection and ablation (1.9% vs. 0.6%, P = 0.017). Five-year OS rates were not different (39.3% vs. 33.9%, P = 0.145). CONCLUSION: Combined resection and ablation should be available and considered as an alternative to resection alone in any patient with multiple metastases.

BACKGROUND: Approximately 70% of patients with colorectal liver metastases (CRLM) experiences intrahepatic recurrence after initial liver resection. This study assessed outcomes and hospital variation in repeat liver resections (R-LR). METHODS: This population-based study included all patients who underwent liver resection for CRLM between 2014 and 2022 in the Netherlands. Overall survival (OS) was collected for patients operated on between 2014 and 2018 by linkage to the insurance database. RESULTS: Data of 7479 liver resections (1391 (18.6%) repeat and 6088 (81.4%) primary) were analysed. Major morbidity and mortality were not different. Factors associated with major morbidity included ASA 3+, major liver resection, extrahepatic disease, and open surgery. Five-year OS after repeat versus primary liver resection was 42.3% versus 44.8%, P = 0.37. Factors associated with worse OS included largest CRLM >5 cm (aHR 1.58, 95% CI: 1.07-2.34, P = 0.023), >3 CRLM (aHR 1.33, 95% CI: 1.00-1.75, P = 0.046), extrahepatic disease (aHR 1.60, 95% CI: 1.25-2.04, P = 0.001), positive tumour margins (aHR 1.42, 95% CI: 1.09-1.85, P = 0.009). Significant hospital variation in performance of R-LR was observed, median 18.9% (8.2% to 33.3%). CONCLUSION: Significant hospital variation was observed in performance of R-LR in the Netherlands reflecting different treatment decisions upon recurrence. On a population-based level R-LR leads to satisfactory survival.

INTRODUCTION: This study investigates the incidence of extrahepatic perfusion and incomplete hepatic perfusion at intraoperative methylene blue testing and on postoperative nuclear imaging in patients undergoing hepatic arterial infusion pump (HAIP) chemotherapy. METHODS: The first 150 consecutive patients who underwent pump implantation in the Netherlands were included. All patients underwent surgical pump implantation with the catheter in the gastroduodenal artery. All patients underwent intraoperative methylene blue testing and postoperative nuclear imaging (99mTc-Macroaggregated albumin SPECT/CT) to determine perfusion via the pump. RESULTS: Patients were included between January-2018 and December-2021 across eight centers. During methylene blue testing, 29.3% had extrahepatic perfusion, all successfully managed intraoperatively. On nuclear imaging, no clinically relevant extrahepatic perfusion was detected (0%, 95%CI: 0.0-2.5%). During methylene blue testing, 2.0% had unresolved incomplete hepatic perfusion. On postoperative nuclear imaging, 8.1% had incomplete hepatic perfusion, leading to embolization in only 1.3%. CONCLUSION: Methylene blue testing during pump placement for intra-arterial chemotherapy identified extrahepatic perfusion in 29.3% of patients, but could be resolved intraoperatively in all patients. Postoperative nuclear imaging found no clinically relevant extrahepatic perfusion and led to embolization in only 1.3% of patients. The role of routine nuclear imaging after HAIP implantation should be studied in a larger cohort.

BACKGROUND: Postoperative mortality and morbidity rates are high in patients with obstructing colon cancer (OCC). Different treatment options have been evaluated over the years, mainly for left sided OCC. Optimising the preoperative health condition in elective colorectal cancer (CRC) treatment shows promising results. The aim of this study is to determine whether preoptimisation is feasible in patients with OCC, with a special interest/focus on right-sided OCC, and if, ultimately, optimisation reduces mortality and morbidity (stoma rates, major and minor complications) rates in OCC. METHODS: This is a prospective registration study including all patients presenting with OCC in our hospital. Patients with OCC, treated with curative intent, will be screened for eligibility to receive preoptimisation before surgery. The preoptimisation protocol includes; decompression of the small bowel with a NG-tube for right sided obstruction and SEMS or decompressing ileostomy or colostomy, proximal to the site of obstruction, for left sided colonic obstructions. For the additional work-up, additional nutrition by means of parenteral feeding (for patients who are dependent on a NG tube) or oral/enteral nutrition (in case the obstruction is relieved) is provided. Physiotherapy with attention to both cardio and muscle training prior surgical resection is provided. The primary endpoint is complication-free survival (CFS) at the 90 day period after hospitalisation. Secondary outcomes include pre- and postoperative complications, patient- and tumour characteristics, surgical procedures, total in hospital stay, creation of decompressing and/or permanent ileo- or colostomy and long-term (oncological) outcomes. DISCUSSION: Preoptimisation is expected to improve the preoperative health condition of patients and thereby reduce postoperative complications. TRIAL REGISTRATION: Trial Registry: NL8266 date of registration: 06-jan-2020. STUDY STATUS: Open for inclusion.

PURPOSE: The aim of this study was to compare baseline characteristics, 90-day mortality and overall survival (OS) between patients with obstructing and non-obstructing right-sided colon cancer at a national level. METHODS: All patients who underwent resection for right-sided colon cancer between January 2015 and December 2016 were selected from the Netherlands Cancer Registry and stratified for obstruction. Primary outcome was 5-year OS after excluding 90-day mortality as assessed by the Kaplan-Meier and multivariable Cox regression analysis. RESULTS: A total of 525 patients (7%) with obstructing and 6891 patients (93%) with non-obstructing right-sided colon cancer were included. Patients with right-sided obstructing colon cancer (OCC) were older and had more often transverse tumour location, and the pathological T and N stage was more advanced than in those without obstruction (p < 0.001). The 90-day mortality in patients with right-sided OCC was higher compared to that in patients with non-obstructing colon cancer: 10% versus 3%, respectively (p < 0.001). The 5-year OS of those surviving 90 days postoperatively was 42% in patients with OCC versus 73% in patients with non-obstructing colon cancer, respectively (p < 0.001). Worse 5-year OS was found in patients with right-sided OCC for all stages. Obstruction was an independent risk factor for decreased OS in right-sided colon cancer (HR 1.79, 95% CI 1.57-2.03). CONCLUSION: In addition to increased risk of postoperative mortality, a stage-independent worse 5-year OS after excluding 90-day mortality was found in patients with right-sided OCC compared to patients without obstruction.

INTRODUCTION: In 2017, the Southampton guideline stated that minimally invasive liver resections (MILR) should considered standard practice for minor liver resections. This study aimed to assess recent implementation rates of minor MILR, factors associated with performing MILR, hospital variation, and outcomes in patients with colorectal liver metastases (CRLM). METHODS: This population-based study included all patients who underwent minor liver resection for CRLM in the Netherlands between 2014 and 2021. Factors associated with MILR and nationwide hospital variation were assessed using multilevel multivariable logistic regression. Propensity-score matching (PSM) was applied to compare outcomes between minor MILR and minor open liver resections. Overall survival (OS) was assessed with Kaplan-Meier analysis on patients operated until 2018. RESULTS: Of 4,488 patients included, 1,695 (37.8%) underwent MILR. PSM resulted in 1,338 patients in each group. Implementation of MILR increased to 51.2% in 2021. Factors associated with not performing MILR included treatment with preoperative chemotherapy (aOR 0.61 CI:0.50-0.75, p < 0.001), treatment in a tertiary referral hospital (aOR 0.57 CI:0.50-0.67, p < 0.001), and larger diameter and number of CRLM. Significant hospital variation was observed in use of MILR (7.5% to 93.0%). After case-mix correction, six hospitals performed fewer, and six hospitals performed more MILRs than expected. In the PSM cohort, MILR was associated with a decrease in blood loss (aOR 0.99 CI:0.99-0.99, p < 0.01), cardiac complications (aOR 0.29, CI:0.10-0.70, p = 0.009), IC admissions (aOR 0.66, CI:0.50-0.89, p = 0.005), and shorter hospital stay (aOR CI:0.94-0.99, p < 0.01). Five-year OS rates for MILR and OLR were 53.7% versus 48.6%, p = 0.21. CONCLUSION: Although uptake of MILR is increasing in the Netherlands, significant hospital variation remains. MILR benefits short-term outcomes, while overall survival is comparable to open liver surgery.

BACKGROUND: The optimal treatment sequence for patients with synchronous colorectal liver metastases (CRLM) remains uncertain. This study aimed to assess factors associated with the use of simultaneous resections and impact on hospital variation. METHOD: This population-based study included all patients who underwent liver surgery for synchronous colorectal liver metastases between 2014 and 2019 in the Netherlands. Factors associated with simultaneous resection were identified. Short-term surgical outcomes of simultaneous resections and factors associated with 30-day major morbidity were evaluated. RESULTS: Of 2146 patients included, 589 (27%) underwent simultaneous resection in 28 hospitals. Simultaneous resection was associated with age, sex, BMI, number, size and bilobar distribution of CRLM, and administration of preoperative chemotherapy. More minimally invasive and minor resections were performed in the simultaneous group. Hospital variation was present (range 2.4%-83.3%) with several hospitals performing simultaneous procedures more and less frequently than expected. Simultaneous resection resulted in 13% 30-day major morbidity, and 1% mortality. ASA classification ≥3 was independently associated with higher 30-day major morbidity after simultaneous resection (aOR 1.97, CI 1.10-3.42, p = 0.018). CONCLUSION: Distinctive patient and tumour characteristics influence the choice for simultaneous resection. Remarkable hospital variation is present in the Netherlands.

PURPOSE: The extended role of breast-conserving surgery (BCS) in the neoadjuvant setting may raise concerns on the oncologic safety of BCS compared to mastectomy. This study compared long-term outcomes after neoadjuvant chemotherapy (NAC) between patients treated with BCS and mastectomy. METHODS: All breast cancer patients treated with NAC from 2008 until 2017 at the Amphia Hospital (the Netherlands) were included. Disease-free and overall survival were compared between BCS and mastectomy with survival functions. Multivariable Cox proportional hazard regression was performed to determine prognostic variables for disease-free survival. RESULTS: 561 of 612 patients treated with NAC were eligible: 362 (64.5%) with BCS and 199 (35.5%) with mastectomy. Median follow-up was 6.8 years (0.9-11.9). Mastectomy patients had larger tumours and more frequently node-positive or lobular cancer. Unadjusted five-year disease-free survival was 90.9% for BCS versus 82.9% for mastectomy (p = .004). Unadjusted five-year overall survival was 95.3% and 85.9% (p < .001), respectively. In multivariable analysis, clinical T4 (cT4) (HR 3.336, 95% CI 1.214-9.165, p = .019) and triple negative disease (HR 5.946, 95% CI 2.703-13.081, p < .001) were negative predictors and pathologic complete response of the breast (HR 0.467, 95% CI 0.238-0.918, p = .027) and axilla (HR 0.332, 95% CI 0.193-0.572, p = .001) were positive predictors for disease-free survival. Mastectomy versus BCS was not a significant predictor for disease-free survival when adjusted for the former variables (unadjusted HR 2.13 (95%CI: 1.4-3.24), adjusted HR 1.31 (95%CI: 0.81-2.13)). In the BCS group, disease-free and overall survival did not differ significantly between cT1, cT2 or cT3 tumours. CONCLUSION: BCS does not impair disease-free and overall survival in patients treated with NAC. Tumour biology and treatment response are significant prognostic indicators.

BACKGROUND: Treatment for obstructing colon cancer (OCC) is controversial because the outcome of acute resection is less favorable than for patients without obstruction. Few studies have investigated curable right-sided OCC, and patients with OCC usually undergo acute resection. This study aimed to better understand the outcome and best management of potentially curable right-sided OCC. METHODS: A systematic review of studies was performed with a focus on differences in mortality and morbidity between emergency resection and staged treatment for patients with potentially curable right-sided OCC. In March 2019, the study searched Embase, Medline, Web of Science, Cochrane, and Google scholar databases according to PRISMA guidelines using search terms related to "colon tumour," "stenosis or obstruction and surgery," and "decompression or stents." All English-language studies reporting emergency or staged treatment for potentially curable right-sided OCC were included in the review. Emergency resection and staged resection were compared for mortality, morbidity, complications, and survival. RESULTS: Nine studies were found to be eligible and comprised 600 patients treated with curative intent for their right-sided OCC by emergency resection or staged resection. The mean overall complication rate was 42% (range 19-54%) after emergency resection, and 30% (range 7-44%) after staged treatment. The average mortality rate was 7.2% (range 0-14.5%) after emergency resection and 1.2% (range 0-6.3%) after staged treatment. The 5-year disease-free and overall survival rates were comparable for the two treatments. CONCLUSIONS: The patients who received staged treatment for right-sided OCC had lower mortality rates, fewer complications, and fewer anastomotic leaks and stoma creations than the patients who had emergency resection.

BACKGROUND: Older patients often have iron deficiency anemia before surgery, which can be effectively treated with intravenous iron supplementation (IVIS). Anemia and blood transfusions are associated with an increased risk of delirium. The aim of this research was to assess the effectiveness and safety of using IVIS in a prehabilitation program. MATERIAL AND METHODS: Patients ≥70 y who underwent abdominal surgery between November 2015 and June 2018 were included in this single-center prospective cohort study. All patients were prehabilitated; however, only anemic patients received a single dose of 1000 mg intravenous iron (ferric carboxymaltose) to increase preoperative hemoglobin levels (IVIS group). Nonanemic patients received standard care (SC). The hemoglobin levels (primary outcome) were assessed at the outpatient clinic visit, at admission, and at discharge. Secondary outcomes were postoperative delirium, postoperative anemia, blood transfusion, complications other than delirium, and length of hospital stay. All outcomes were compared between the IVIS group and SC group. RESULTS: Of all patients (n = 248), 97 anemic patients received IVIS (39%). Of the anemic patients, 50 patients (52%) had iron deficiency. Initial differences in hemoglobin concentrations between the IVIS group and SC group at T1 and T2 (7.2 versus 8.8; P < 0.001 and 7.4 versus 8.6; P = 0.023, respectively) were no longer present at discharge (6.6 versus 7.2; P = 0.35). No statistically significant differences were observed for all secondary outcomes between the IVIS group and the SC group. No infusion-related adverse events occurred. CONCLUSIONS: Adding IVIS to prehabilitation programs is safe and diminishes differences in these concentrations between preoperatively anemic and nonanemic patients. IVIS may be worthwhile as an additional component of prehabilitation programs. Results merit further investigation.

Objectives: This study aimed to demonstrate the impact of elective major abdominal surgery and subsequent postoperative delirium on quality of life (QOL; primary outcome), cognitive functioning and depressive symptoms (secondary outcomes) in older surgical patients.Method: A single-centre, longitudinal prospective cohort study was conducted between November 2015 and June 2018, including patients ≥70 years old who underwent surgery for colorectal cancer or an abdominal aortic aneurysm. They were followed-up at discharge and at 6 and 12 months postoperatively until June 2019. QOL was assessed with the World Health Organization Quality of Life-BREF questionnaire (WHOQOL-BREF). Cognitive functioning was measured with the Mini-Mental State Examination and depressive symptoms with the CES-D 16.Results: In all patients (n = 265), physical and psychological health were significantly lower at discharge compared to baseline (p < 0.001 for both domains). Physical health restored after 6 months, but psychological health remained decreased for the complete study period. Psychological, social and environmental QOL were significantly worse in patients with delirium compared to patients without (p = 0.001, p = 0.006 and p = 0.001 respectively). The cognitive functioning score was significantly lower at baseline in patients with delirium compared to those without (p = 0.006). Patients with delirium had a significantly higher CES-D 16 score compared to those without after 12 months (p = 0.027).Conclusion: Physical and psychological QOL were decreased in the early postoperative period. While physical health was restored after 6 and 12 months, psychological health remained decreased. After 12 months, postoperative delirium resulted in worse psychological, social and environmental QOL and more depressive symptoms. Decreased cognitive functioning may be a risk factor for delirium.

BACKGROUND: Little is known about metastatic patterns in patients with obstructing colorectal cancer (CRC). OBJECTIVE: The aim of this study was to determine if metastatic patterns in patients with CRC differ between patients with or without obstruction. METHODS: This single-center, observational, retrospective cohort study includes patients who underwent surgery for CRC between 2004 and 2015 in our hospital. Patients were divided into two groups-patients with or without obstructing CRC. All anatomic sites of distant metastases were reported. Differences in synchronous and metachronous metastases were compared between both groups. RESULTS: A total of 2595 patients were included for analysis, of whom 315 (12%) presented with obstructing CRC. Synchronous metastases were diagnosed in 483 patients (19%). Patients with obstructing CRC and synchronous metastases, were diagnosed with peritoneal metastases more often than patients without obstruction (37% vs. 16%; p < 0.01). With regard to the location of the tumor, obstructing right-sided CRC patients were diagnosed with peritoneal metastases more often than patients without obstruction (52% vs. 21%; p < 0.01). Additionally, metachronous metastases were found significantly more often in patients with obstructing CRC (27%) compared with patients without obstruction (15%; p < 0.01). CONCLUSIONS: Patients with obstructing CRC have more advanced tumor stage compared with patients without obstructing CRC. Synchronous peritoneal metastases are more often encountered in patients with obstructing CRC compared with patients without obstruction. This difference is due to the raised presence of synchronous peritoneal metastases in patients with obstructed right-sided colonic cancer. Furthermore, metachronous metastases are more often found in patients with obstructing CRC.

OBJECTIVES: According to new Dutch guidelines for rectal cancer, MRI-defined tumour stage determines whether preoperative radiotherapy is indicated. Therefore, we sought to evaluate if preoperative MRI accurately predicts the indication for neoadjuvant treatment in rectal cancer cases in daily practice according to the new Dutch guidelines. METHODS: Data for all rectal cancer patients who underwent mesorectal excision in our hospital, between January 2011 and January 2018 were collected retrospectively. We compared histopathologic outcome with tumour staging on preoperative MRI for patients who received no radiotherapy prior to resection or short-course radiotherapy directly followed by resection. RESULTS: Of 223 patients treated according to the old guidelines, 94% received neoadjuvant therapy. Of 301 patients treated according to the new guidelines, only 49% did. Under the old guidelines, MRI predicted lymph node metastases with a sensitivity of 74.2% and a specificity of 52.6%. With the new guidelines, sensitivity was 47.5% and specificity was 77.3%. The new guidelines resulted in 45% more patients not being exposed to disadvantages of radiotherapy, but 13% of all patients were undertreated. CONCLUSIONS: Concordance between clinical lymph node staging on preoperative MRI and histopathologic staging is limited, resulting in many rectal cancer patients not receiving adequate neoadjuvant therapy.

PURPOSE: The long-term outcomes of surgery followed by delirium after multimodal prehabilitation program are largely unknown. We conducted this study to assess the effects of prehabilitation on 1-year mortality and of postoperative delirium on 1-year mortality and functional outcomes. METHODS: The subjects of this study were patients aged ≥ 70 years who underwent elective surgery for abdominal aortic aneurysm (AAA) or colorectal cancer (CRC) between January 2013, and June 2018. A prehabilitation program was implemented in November 2015, which aimed to optimize physical health, nutritional status, factors of frailty and preoperative anemia prior to surgery. The outcomes were assessed as mortality after 6 and 12 months, compared between the two treatment groups; and mortality and functional outcomes, compared between patients with and those without delirium. RESULTS: There were 627 patients (controls N = 360, prehabilitation N = 267) included in this study. Prehabilitation did not reduce mortality after 1 year (HR 1.31 [95% CI 0.75-2.30]; p = 0.34). Delirium was significantly associated with 1-year mortality (HR 4.36 [95% CI 2.45-7.75]; p < 0.001) and with worse functional outcomes after 6 and 12 months (KATZ ADL p = 0.013 and p = 0.004; TUG test p = 0.041 and p = 0.011, respectively). CONCLUSIONS: The prehabilitation program did not reduce 1-year mortality. Delirium and the burden of comorbidity are both independently associated with an increased risk of 1-year mortality and delirium is associated with worse functional outcomes.

BACKGROUND: Due to the increase in elderly patients who undergo major abdominal surgery there is a subsequent increase in postoperative complications, prolonged hospital stays, health-care costs and mortality rates. Delirium is a frequent and severe complication in the 'frail' elderly patient. Different preoperative approaches have been suggested to decrease incidence of delirium by improving patients' baseline health. Studies implementing these approaches are often heterogeneous, have a small sample and do not provide high-quality or successful strategies. The aim of this study is to prevent postoperative delirium and other complications by implementing a unique multicomponent and multidisciplinary prehabilitation program. METHODS: This is a single-center controlled before-and-after study. Patients aged ≥70 years in need of surgery for colorectal cancer or an abdominal aortic aneurysm are considered eligible. Baseline characteristics (such as factors of frailty, physical condition and nutritional state) are collected prospectively. During 5 weeks prior to surgery, patients will follow a prehabilitation program to optimize overall health, which includes home-based exercises, dietary advice and intravenous iron infusion in case of anaemia. In case of frailty, a geriatrician will perform a comprehensive geriatric assessment and provide additional preoperative interventions when deemed necessary. The primary outcome is incidence of delirium. Secondary outcomes are length of hospital stay, complication rate, institutionalization, 30-day, 6- and 12-month mortality, mental health and quality of life. Results will be compared to a retrospective control group, meeting the same inclusion and exclusion criteria, operated on between January 2013 and October 2015. Inclusion of the prehabilitation cohort started in November 2015; data collection is ongoing. DISCUSSION: This is the first study to investigate the effect of prehabilitation on postoperative delirium. The aim is to provide evidence, based on a large sample size, for a standardized multicomponent strategy to improve patients' preoperative physical and nutritional status in order to prevent postoperative delirium and other complications. A multimodal intervention was implemented, combining physical, nutritional, mental and hematinic optimization. This research involves a large cohort, including patients most at risk for postoperative adverse outcomes. TRIAL REGISTRATION: The protocol is retrospectively registered at the Netherlands National Trial Register (NTR) number: NTR5932 . Date of registration: 05-04-2016.

BACKGROUND: While most of the evidence on minimally invasive liver surgery (MILS) is derived from expert centers, nationwide outcomes remain underreported. This study aimed to evaluate the implementation and outcome of MILS on a nationwide scale. METHODS: Electronic patient files were reviewed in all Dutch liver surgery centers and all patients undergoing MILS between 2011 and 2016 were selected. Operative outcomes were stratified based on extent of the resection and annual MILS volume. RESULTS: Overall, 6951 liver resections were included, with a median annual volume of 50 resections per center. The overall use of MILS was 13% (n = 916), which varied from 3% to 36% (P < 0.001) between centers. The nationwide use of MILS increased from 6% in 2011 to 23% in 2016 (P < 0.001). Outcomes of minor MILS were comparable with international studies (conversion 0-13%, mortality <1%). In centers which performed ≥20 MILS annually, major MILS was associated with less conversions (14 (11%) versus 41 (30%), P < 0.001), shorter operating time (184 (117-239) versus 200 (139-308) minutes, P = 0.010), and less overall complications (37 (30%) versus 58 (42%), P = 0.040). CONCLUSION: The nationwide use of MILS is increasing, although large variation remains between centers. Outcomes of major MILS are better in centers with higher volumes.

OBJECTIVE: Since the implementation of new guidelines for rectal cancer in The Netherlands in April 2014, clinical stage as seen at preoperative MRI indicates whether neoadjuvant therapy is necessary before rectal cancer surgery. Therefore, the importance of correct MRI interpretation has increased. The aim of this study was to evaluate the completeness of MRI reports of rectal cancer and the effect of implementation of the new guidelines and standardized reporting on the completeness of these reports. MATERIALS AND METHODS: Data were collected from all patients who consecutively underwent rectal cancer surgery at one hospital between January 2011 and July 2017. Data were extracted from electronic patient records. RESULTS: The study included 492 MRI examinations. Before implementation of the new guidelines, a median of 4 of 10 items (interquartile range [IQR], 3-6 items) were described in each MRI report. After implementation of the new guidelines, the number of items described improved significantly (median, 7 items; IQR, 6-8 items; p < 0.001). Implementation of a standardized report led to further significant improvement (median, 9 items; IQR, 9-10 items; p < 0.001). The items scored most frequently were distance between the tumor and the anal verge (85.6%) and length of the tumor (87.6%). The items scored least were presence or absence of extramural venous invasion (21.1%) and morphologic features of the tumor (24.6%). CONCLUSION: Implementation of a standardized protocol and a standardized reporting system for MRI in preoperative staging of rectal cancer results in a more complete MRI report.

BACKGROUND: The association between diverticulitis and colorectal cancer (CRC) remains unclear, though both share epidemiological characteristics. The aim of this study was to investigate whether there is higher risk for CRC after an episode of uncomplicated diverticulitis. Furthermore, in cases of CRC, we sought to determine specific tumour characteristics. METHODS: This retrospective observational study includes patients with acute diverticulitis (Hinchey 0 and 1) who were conservatively treated with or without antibiotics between 2008 and 2013. Patients with endoscopic follow-up were included for analysis. Tumour characteristics of patients diagnosed with CRC during colonoscopic follow-up according to patients' presentation of alarm symptoms were considered to be the primary endpoint. RESULTS: A total of 977 patients were conservatively treated for an episode of acute diverticulitis, 645 of whom underwent colonoscopy during follow-up. Ten patients were diagnosed with CRC, nine of whom exhibited alarm symptoms. One patient was diagnosed with stage I disease, 4 had stage II, and 5 had stage III disease. CONCLUSIONS: This study strongly suggests that even though CRC is rare after uncomplicated diverticulitis, in cases of alarm symptoms, a colonoscopy is indicated. In cases where CRC is diagnosed, it is often advanced with a higher TNM stage and poor prognosis.
