Robot-assisted and fluorescence-guided remnant-cholecystectomy: a prospective dual-center cohort study

Background: Abdominal symptoms after cholecystectomy may be caused by gallstones in a remnant gallbladder or a long cystic duct stump. Resection of a remnant gallbladder or cystic duct stump is associated with an increased risk of conversion and bile duct or vascular injuries. We prospectively investigated the additional value of robotic assistance and fluorescent bile duct illumination in redo biliary surgery.Methods: In this prospective two-centre observational cohort study, 28 patients were included with an indication for redo biliary surgery because of remnant stones in a remnant gallbladder or long cystic duct stump. Surgery was performed with the da Vinci X & REG; and Xi & REG; robotic system. The biliary tract was visualised in the fluorescence Firefly & REG; mode shortly after intravenous injection of indocyanine green.Results: There were no conversions or perioperative complications, especially no vascular or bile duct injuries. Fluorescence-based illumination of the extrahepatic bile ducts was successful in all cases. Symptoms were resolved in 27 of 28 patients. Ten patients were treated in day care and 13 patients were discharged the day after surgery.Conclusion: Robot-assisted fluorescence-guided surgery for remnant gallbladder or cystic duct stump resection is safe, effective and can be done in day-care setting.Surgical oncolog

Long-term quality of life and exocrine and endocrine insufficiency after pancreatic surgery: a multicenter, cross-sectional study

Background: Data regarding long-term quality of life and exocrine and endocrine insufficiency after pancreatic surgery for premalignant and benign (non-pancreatitis) disease are lacking. Methods: This cross-sectional study included patients >3 years after pancreatoduodenectomy or left pancreatectomy in six Dutch centers (2006-2016). Outcomes were measured with the EQ-5D-5L, the EORTC QLQ-C30, an exocrine and endocrine pancreatic insufficiency questionnaire, and PAID20. Results: Questionnaires were completed by 153/183 patients (response rate 84%, median follow-up 6.3 years). Surgery related complaints were reported by 72/153 patients (47%) and 13 patients (8.4%) would not undergo this procedure again. The VAS (EQ-5D-5L) was 76 +/- 17 versus 82 +/- 0.4 in the general population (p < 0.001). The mean global health status (QLQ-C30) was 78 +/- 17 versus 78 +/- 17, p = 1.000. Fatigue, insomnia, and diarrhea were clinically relevantly worse in patients. Exocrine pancreatic insufficiency was reported by 62 patients (41%) with relieve of symptoms by enzyme supplementation in 48%. New-onset diabetes mellitus was present in 22 patients (14%). The median PAID20 score was 6.9/20 (IQR 2.5-17.8). Conclusion: Although generic quality of life after pancreatic resection for pre-malignant and benign disease was similar to the general population and diabetes-related distress was low, almost half suffered from a range of symptoms highlighting the need for long-term counseling.Cellular mechanisms in basic and clinical gastroenterology and hepatolog

Hospital variation in combined liver resection and thermal ablation for colorectal liver metastases and impact on short-term postoperative outcomes: a nationwide population-based study

Background: Combining resection and thermal ablation can improve short-term postoperative outcomes in patients with colorectal liver metastases (CRLM). This study assessed nationwide hospital variation and short-term postoperative outcomes after combined resection and ablation.Methods: In this population-based study, all CRLM patients who underwent resection in the Netherlands between 2014 and 2018 were included. After propensity score matching for age, ASA-score, Charlson-score, diameter of largest CRLM, number of CRLM and earlier resection, postoperative outcomes were compared. Postoperative complicated course (PCC) was defined as discharge after 14 days or a major complication or death within 30 days of surgery.Results: Of 4639 included patients, 3697 (80%) underwent resection and 942 (20%) resection and ablation. Unadjusted percentage of patients who underwent resection and ablation per hospital ranged between 4 and 44%. Hospital variation persisted after case-mix correction. After matching, 734 patients remained in each group. Hospital stay (median 6 vs. 7 days, p = 0.011), PCC (11% vs. 14.7%, p = 0.043) and 30-day mortality (0.7% vs. 2.3%, p = 0.018) were lower in the resection and ablation group. Differences faded in multivariable logistic regression due to inclusion of major hepatectomy.Conclusion: Significant hospital variation was observed in the Netherlands. Short-term postoperative outcomes were better after combined resection and ablation, attributed to avoiding complications associated with major hepatectomy.Imaging- and therapeutic targets in neoplastic and musculoskeletal inflammatory diseas

Factors associated with failure to rescue after liver resection and impact on hospital variation: a nationwide population-based study

Background: Failure to rescue (FTR) is defined as postoperative complications leading to mortality. This nationwide study aimed to assess factors associated with FTR and hospital variation in FTR after liver surgery.Methods: All patients who underwent liver resection between 2014 and 2017 in the Netherlands were included. FTR was defined as in-hospital or 30-day mortality after complications Dindo grade >= 3a. Variables associated with FTR and nationwide hospital variation were assessed using multivariable lo-gistic regression.Results: Of 4961 patients included, 3707 (74.4%) underwent liver resection for colorectal liver me-tastases, 379 (7.6%) for other metastases, 526 (10.6%) for hepatocellular carcinoma and 349 (7.0%) for biliary cancer. Thirty-day major morbidity was 11.5%. Overall mortality was 2.3%. FTR was 19.1%. Age 65-80 (aOR: 2.86, CI:1.01-12.0, p = 0.049), ASA 3+ (aOR:2.59, CI: 1.66-4.02, p < 0.001), liver cirrhosis (aOR:4.15, CI:1.81-9.22, p < 0.001), biliary cancer (aOR:3.47, CI: 1.73-6.96, p < 0.001), and major resection (aOR:6.46, CI: 3.91-10.9, p < 0.001) were associated with FTR. Postoperative liver failure (aOR: 26.9, CI: 14.6-51.2, p < 0.001), cardiac (aOR: 2.62, CI: 1.27-5.29, p = 0.008) and thromboembolic complications (aOR: 2.49, CI: 1.16-5.22, p = 0.017) were associated with FTR. After case-mix correction, no hospital variation in FTR was observed.Conclusion: FTR is influenced by patient demographics, disease and procedural burden. Prevention of postoperative liver failure, cardiac and thromboembolic complications could decrease FTR.Surgical oncolog

Impact of nationwide enhanced implementation of best practices in pancreatic cancer care (PACAP-1):a multicenter stepped-wedge cluster randomized controlled trial

Background: Pancreatic cancer has a very poor prognosis. Best practices for the use of chemotherapy, enzyme replacement therapy, and biliary drainage have been identified but their implementation in daily clinical practice is often suboptimal. We hypothesized that a nationwide program to enhance implementation of these best practices in pancreatic cancer care would improve survival and quality of life. Methods/design: PACAP-1 is a nationwide multicenter stepped-wedge cluster randomized controlled superiority trial. In a per-center stepwise and randomized manner, best practices in pancreatic cancer care regarding the use of (neo)adjuvant and palliative chemotherapy, pancreatic enzyme replacement therapy, and metal biliary stents are implemented in all 17 Dutch pancreatic centers and their regional referral networks during a 6-week initiation period. Per pancreatic center, one multidisciplinary team functions as reference for the other centers in the network. Key best practices were identified from the literature, 3 years of data from existing nationwide registries within the Dutch Pancreatic Cancer Project (PACAP), and national expert meetings. The best practices follow the Dutch guideline on pancreatic cancer and the current state of the literature, and can be executed within daily clinical practice. The implementation process includes monitoring, return visits, and provider feedback in combination with education and reminders. Patient outcomes and compliance are monitored within the PACAP registries. Primary outcome is 1-year overall survival (for all disease stages). Secondary outcomes include quality of life, 3- and 5-year overall survival, and guideline compliance. An improvement of 10% in 1-year overall survival is considered clinically relevant. A 25-month study duration was chosen, which provides 80% statistical power for a mortality reduction of 10.0% in the 17 pancreatic cancer centers, with a required sample size of 2142 patients, corresponding to a 6.6% mortality reduction and 4769 patients nationwide. Discussion: The PACAP-1 trial is designed to evaluate whether a nationwide program for enhanced implementation of best practices in pancreatic cancer care can improve 1-year overall survival and quality of life. Trial registration: ClinicalTrials.gov, NCT03513705. Trial opened for accrual on 22th May 2018

Hospital variation and outcomes of simultaneous resection of primary colorectal tumour and liver metastases: a population-based study

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
