Background: Thoracic epidural analgesia is the standard postoperative pain management strategy in esophageal cancer surgery. However, paravertebral block analgesia may achieve comparable pain control while inducing less side effects, which may be beneficial for postoperative recovery. This study primarily aims to compare the postoperative quality of recovery between paravertebral catheter versus thoracic epidural analgesia in patients undergoing minimally invasive esophagectomy.Methods: This study represents a randomized controlled superiority trial. A total of 192 patients will be randomized in 4 Dutch high-volume centers for esophageal cancer surgery. Patients are eligible for inclusion if they are at least 18 years old, able to provide written informed consent and complete questionnaires in Dutch, scheduled to undergo minimally invasive esophagectomy with two-field lymphadenectomy and an intrathoracic anastomosis, and have no contra-indications to either epidural or paravertebral analgesia. The primary outcome is the quality of postoperative recovery, as measured by the Quality of Recovery-40 (QoR-40) questionnaire on the morning of postoperative day 3. Secondary outcomes include the QoR-40 questionnaire score Area Under the Curve on postoperative days 1-3, the integrated pain and systemic opioid score and patient satisfaction and pain experience according to the International Pain Outcomes (IPO) questionnaire, and cost-effectiveness. Furthermore, the groups will be compared regarding the need for additional rescue medication on postoperative days 0-3, technical failure of the pain treatment, duration of anesthesia, duration of surgery, total postoperative fluid administration day 0-3, postoperative vasopressor and inotrope use, length of urinary catheter use, length of hospital stay, postoperative complications, chronic pain at six months after surgery, and other adverse effects.Discussion: In this study, it is hypothesized that paravertebral analgesia achieves comparable pain control while causing less side-effects such as hypotension when compared to epidural analgesia, leading to shorter postoperative length of stay on a monitored ward and superior quality of recovery. If this hypothesis is confirmed, the results of this study can be used to update the relevant guidelines on postoperative pain management for patients undergoing minimally invasive esophagectomy.Trial Registration: Netherlands Trial Registry, NL8037.

Esophageal and gastric cancer is associated with a poor prognosis since many patients develop recurrent disease. Treatment requires specific expertise and a structured multidisciplinary approach. In the Netherlands, this type of expertise is mainly found at the University Medical Centers ( UMCs) and a few specialized nonacademic centers. Aim of this study is to implement a national infrastructure for research to gain more insight in the etiology and prognosis of esophageal and gastric cancer and to evaluate and improve the response on (neoadjuvant) treatment. Clinical data are collected in a prospective database, which is linked to the patients' biomaterial. The collection and storage of biomaterial is performed according to standard operating procedures in all participating UMCs as established within the Parelsnoer Institute. The collected biomaterial consists of tumor biopsies, blood samples, samples of malignant and healthy tissue of the resected specimen and biopsies of recurrence. The collected material is stored in the local biobanks and is encoded to respect the privacy of the donors. After approval of the study was obtained from the Institutional Review Board, the first patient was included in October 2014. The target aim is to include 300 patients annually. In conclusion, the eight UMCs of the Netherlands collaborated to establish a nationwide database of clinical information and biomaterial of patients with esophageal and gastric cancer. Due to the national coverage, a high number of patients are expected to be included. This will provide opportunity for future studies to gain more insight in the etiology, treatment and prognosis of esophageal and gastric cancer. [ABSTRACT FROM AUTHOR]

Background and aim This nationwide population-based study analyzed the outcome of local treatment for oligometastatic esophagogastric cancer in The Netherlands. Methods Patients with synchronous or metachronous oligometastasis (i.e. distant metastasis in 1 organ/extra-regional lymph node station) from esophagogastric cancer were eligible for inclusion from Netherlands Cancer Registry. Patients who underwent local treatment (i.e. metastasectomy or stereotactic body radiation therapy [SBRT]) for oligometastasis were included. The overall survival (OS) after diagnosing oligometastasis was determined. Independent prognostic factors for OS were analyzed using a multivariable Cox proportional hazard model. Results Between 2015–2016, some 2,336 eligible patients with oligometastasis were identified of whom 103 (4%) underwent local treatment for oligometastasis. This portion was higher in academic hospitals (10%) compared to non-academic hospitals with esophagogastric resections (5%) or without esophagogastric resections (3%, P  < 0.001). The 103 included patients were predominantly diagnosed with esophageal cancer (85%) with adenocarcinoma histology (80%) and with metachronous oligometastasis (59%). The oligometastasis were located in a distant organ (79%), an extra-regional lymph node station (12%), or the peritoneum (9%). Treatment for oligometastasis included metastasectomy (45%), SBRT (40%), or both (15%), and 21% of patients received additional systemic therapy. Median OS was 18.1 months (95% confidence interval [CI]: 13.9–22.7). The OS rate at 2-year was 36% and at 3-year 23%. Improved OS was independently associated with additional systemic therapy (hazard ratio [HR] 0.47, 95% CI: 0.23–0.96) and better performance scores (HR 0.55, 95% CI: 0.29–0.92). Conclusion A minority of patients underwent local treatment for oligometastatic esophagogastric cancer, which was dependent on the type of hospital of diagnosis. Local treatment for oligometastasis resulted in a median OS of 1.5 years. Systemic therapy combined with local treatment for oligometastasis improved OS. [ABSTRACT FROM AUTHOR]

Introduction: In this retrospective study results from inguinal hernia repair with the Prolene Hernia System (PHS) in a regional training hospital were analysed.Patients and Methods: One-hundred and seventy-eight primary inguinal hernias and thirty-nine recurrent hernias (initial non-mesh repair) were treated with the PHS. The primary endpoint was the recurrence rate. Secondary endpoints were short-term and long-term complications. Pain was evaluated by use of a visual analog scale (VAS, 0-100), and a short-form 36-item questionnaire was used to assess postoperation quality of life. All patients visited the outpatient clinic for a physical examination (100% follow-up).Results: After a median follow-up of 32 months four patients were diagnosed with recurrent herniation (1.8%), three after primary hernia repair (1.6%) and one after recurrent hernia repair (2.6%). Three superficial wound infections (1.3%), three haematomas needing surgical evacuation (1.3%), and two lesions of the spermatic cord (0.9%) were diagnosed. Seven patients (3.2%) suffered from persistent pain (VAS > 40). Average VAS score was 13 (0-80) >24 months after surgery.Conclusion: In a regional training hospital, primary and recurrent inguinal hernias were treated with low recurrence and few complications by use of the PHS.

The standard of care for gastroesophageal cancer patients with hepatic or pulmonary metastases is best supportive care or palliative chemotherapy. Occasionally, patients can be selected for curative treatment instead. This study aimed to evaluate patients who underwent a resection of hepatic or pulmonary metastasis with curative intent. The Dutch national registry for histo- and cytopathology was used to identify these patients. Data were retrieved from the individual patient files. Kaplan–Meier survival analysis was performed. Between 1991 and 2016, 32,057 patients received a gastrectomy or esophagectomy for gastroesophageal cancer in the Netherlands. Of these patients, 34 selected patients received a resection of hepatic metastasis (n = 19) or pulmonary metastasis (n = 15) in 21 different hospitals. Only 4 patients received neoadjuvant therapy before metastasectomy. The majority of patients had solitary, metachronous metastases. After metastasectomy, grade 3 (Clavien–Dindo) complications occurred in 7 patients and mortality in 1 patient. After resection of hepatic metastases, the median potential follow-up time was 54 months. Median overall survival (OS) was 28 months and the 1-, 3-, and 5- year OS was 84%, 41%, and 31%, respectively. After pulmonary metastases resection, the median potential follow-up time was 80 months. The median OS was not reached and the 1-, 3-, and 5- year OS was 67%, 53%, and 53%, respectively. In selected patients with gastroesophageal cancer with hepatic or pulmonary metastases, metastasectomy was performed with limited morbidity and mortality and offered a 5-year OS of 31–53%. Further prospective studies are required. [ABSTRACT FROM AUTHOR]

This article presents a study of inguinal hernia treatment with Prolene hernia system in a Dutch regional training hospital. The results of the study demonstrate that the medium proved less reliable for groin hernia repair than the extended-size or large devices of the same platform. It also reports that the medium bilayer connected mesh devices is not the ideal size to use to repair primary unguinal hernias in adult males.

Background: This study aims to assess the impact of nationwide centralization of surgery on travel distance and travel burden among patients with oesophageal, gastric, and pancreatic cancer according to age in the Netherlands. As centralization of care increases to improve postoperative outcomes, travel distance and experienced burden might increase., Materials and Methods: All patients who underwent surgery between 2006 and 2017 for oesophageal, gastric and pancreatic cancer in the Netherlands were included. Travel distance between patient's home address and hospital of surgery in kilometres was calculated. Questionnaires were used to assess experienced travel burden in a subpopulation (n = 239). Multivariable ordinal logistic regression models were constructed to identify predictors for longer travel distance., Results: Over 23,838 patients were included, in whom median travel distance for surgical care increased for oesophageal cancer (n = 9217) from 18 to 28 km, for gastric cancer (n = 6743) from 9 to 26 km, and for pancreatic cancer (n = 7878) from 18 to 25 km (all p < 0.0001). Multivariable analyses showed an increase in travel distance for all cancer types over time. In general, patients experienced a physical and social burden, and higher financial costs, due to traveling extra kilometres. Patients aged >70 years travelled less often independently (56% versus 68%), as compared to patients aged ≤70 years., Conclusion: With nationwide centralization, travel distance increased for patients undergoing oesophageal, gastric, and pancreatic cancer surgery. Younger patients travelled longer distances and experienced a lower travel burden, as compared to elderly patients. Nevertheless, on a global scale, travel distances in the Netherlands remain limited., Competing Interests: Declaration of competing interest None declared., (Copyright © 2021 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Accumulating evidence of trials demonstrates that patient-reported health-related quality of life (HRQoL) at diagnosis is prognostic for overall survival (OS) in oesophagogastric cancer. However, real-world data are lacking. Moreover, differences in disease stages and tumour-specific symptoms are usually not taken into consideration. The aim of this population-based study was to assess the prognostic value of HRQoL, including tumour-specific scales, on OS in patients with potentially curable and advanced oesophagogastric cancer., Methods: Data were derived from the Netherlands Cancer Registry and the patient reported outcome registry (POCOP). Patients included in POCOP between 2016 and 2018 were stratified for potentially curable (cT1-4aNallM0) or advanced (cT4b or cM1) disease. HRQoL was measured with the EORTC QLQ-C30 and the tumour-specific OG25 module. Cox proportional hazards models assessed the impact of HRQoL, sociodemographic and clinical factors (including treatment) on OS., Results: In total, 924 patients were included. Median OS was 38.9 months in potentially curable patients (n = 795) and 10.6 months in patients with advanced disease (n = 129). Global Health Status was independently associated with OS in potentially curable patients (HR 0.89, 99%CI 0.82-0.97), together with several other HRQoL items: appetite loss, dysphagia, eating restrictions, odynophagia, and body image. In advanced disease, the Summary Score was the strongest independent prognostic factor (HR 0.75, 99%CI 0.59-0.94), followed by fatigue, pain, insomnia and role functioning., Conclusion: In a real-world setting, HRQoL was prognostic for OS in patients with potentially curable and advanced oesophagogastric cancer. Several HRQoL domains, including the Summary Score and several OG25 items, could be used to develop or update prognostic models., (© 2021. The Author(s).)

Background: Minimally invasive gastrectomy has been introduced in Western populations during the last decade. As minimally invasive distal gastrectomy (MIDG) versus total gastrectomy (MITG) are procedures with a different complexity, outcomes may differ. The aim of this population-based cohort study was to evaluate the safety of MIDG and MITG., Materials and Methods: All patients who underwent potentially curative gastrectomy for gastric adenocarcinoma were included from the Dutch Upper GI Cancer Audit (2011-2016). Propensity score matching was applied to create comparable groups of patients receiving open distal gastrectomy (ODG) versus MIDG and open total gastrectomy (OTG) versus MITG, using patient and tumor characteristics. Postoperative outcomes and short-term oncological outcomes were appraised., Results: Of the 1970 eligible patients, 1138 underwent distal gastrectomy and 832 underwent total gastrectomy. For distal gastrectomy, 390 ODG were matched to 288 MIDG patients. Although overall postoperative morbidity and mortality were similar, patients who underwent MIDG encountered less intra-abdominal abscesses (4% vs. 1%, p = 0.039) and wound complications (6% vs. 2%, p = 0.021). The median hospital stay was shorter after MIDGs (9 vs. 7 days, p < 0.001). For total gastrectomy, 323 OTG patients were matched to 258 MITG patients. Overall postoperative morbidity, mortality and hospital stay were similar, whereas the anastomotic leakage rate was higher after MITGs (11% vs. 17%, p = 0.030). Short-term oncological outcomes between both groups were equal for distal and total gastrectomy., Conclusion: Benefits of MIG during the early introduction were demonstrated for distal gastrectomy but not for total gastrectomy. An increased anastomotic leakage rate was encountered for MITG., (Copyright © 2018. Published by Elsevier Ltd.)

Introduction: The aim of this study is to provide insight in accuracy of diagnosing, current treatment and survival in patients with resectable esophageal and gastric neuroendocrine- and mixed adenoneuroendocrine carcinomas (NEC, MANEC)., Methods: All patients with esophageal or gastric (MA)NEC, who underwent surgical resection between 2006 and 2016, were identified from the Dutch national registry for histo- and cytopathology (PALGA). Patients with a neuroendocrine tumor lower than grade 3 were excluded. Data on patients, treatment and outcomes were retrieved from the patient records. Diagnosis by endoscopic biopsy was compared with diagnosis by resection specimen. Kaplan Meier survival analysis was performed., Results: A total of 49 patients were identified in 25 hospitals, including 21 patients with esophageal (MA)NEC and 26 patients with gastric (MA)NEC on resection specimen. Biopsy diagnosis of (MA)NEC was correct in 23/27 patients. However, 20/47 patients with definitive diagnosis of (MA)NEC, were misdiagnosed on biopsy. Neoadjuvant therapy was administered in 13 (62%) esophageal (MA)NECs and 12 (46%) gastric (MA)NECs. Survival curves were similar with and without neoadjuvant therapy. One (4.8%) esophageal (MA)NEC and 4 (15%) gastric (MA)NECs died within 90 days postoperatively. For esophageal (MA)NEC the median overall survival (OS) after surgery was 37 months and 1-, 3- and 5-year OS were 71%, 50% and 35%, respectively. For gastric (MA)NEC, the median OS was 23 months and 1-, 3- and 5-year OS were 62%, 50% and 39%, respectively., Conclusion: Localized esophageal and gastric (MA)NEC are often misdiagnosed on endoscopic biopsies. After resection, long-term survival was achieved in respectively 35% and 39% of patients., (Copyright © 2018. Published by Elsevier Ltd.)

Background: For patients who qualify for perioperative chemotherapy and gastrectomy for gastric cancer, the optimal timing of the postoperative chemotherapy (PC) seems equivocal. The aim of this study was to evaluate the influence of timing of PC on overall survival (OS) in patients receiving perioperative chemotherapy., Methods: Patients undergoing perioperative chemotherapy and gastrectomy with curative intent (2010-2014) were extracted from the nationwide population-based Netherlands Cancer Registry. Timing of PC was analyzed as a linear and categorical variable (<6 weeks, 6-8 weeks, and >8 weeks). Risk factors for a late start of PC (≥6 weeks), and the association between timing of PC and OS were assessed by multivariable regression analyses., Results: Among 1066 patients who underwent perioperative chemotherapy and gastrectomy, 463 (43%) patients started PC. PC was administered within 6 weeks in 208 (45%) patients, within 6-8 weeks in 155 (33%) patients, and after 8 weeks in 100 (22%) patients. A total of 419 (91%) and 351 (76%) patients finished all cycles of preoperative and PC, respectively. A late start of PC was associated with a longer hospital stay (+1 hospital day: OR 1.15, 95% CI [1.08-1.23], p < 0.001). Timing of PC was not associated with OS (6-8 weeks vs. <6 weeks, HR 1.14, 95% CI [0.79-1.65], p = 0.471; >8 weeks vs. <6 weeks, HR 1.04, 95% CI [0.79-1.65], p = 0.872)., Conclusion: Timing of postoperative chemotherapy does not influence survival in patients receiving perioperative chemotherapy for gastric cancer. The results suggest that the early postoperative period may be safely used for recovery and optimizing patients for the start of PC., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Esophagolymphadenectomy is the cornerstone of multimodality treatment for resectable esophageal cancer. The preferred surgical approach is transthoracic, with a two-field lymph node dissection and gastric conduit reconstruction. A minimally invasive approach has been shown to reduce postoperative complications and increase quality of life. Robot-assisted minimally invasive esophagectomy (RAMIE) was developed to facilitate this complex thoracoscopic procedure. RAMIE has been shown to be safe with good oncologic results and reduced morbidity. The use of RAMIE opens new indications for curative surgery in patients with T4b tumors, high mediastinal tumors, and lymph node metastases after neoadjuvant treatment.

Background: Clinical staging of adenocarcinoma of the gastroesophageal junction (GEJ) determines the curative treatment regimen containing either neoadjuvant chemotherapy or chemoradiotherapy followed by either gastrectomy or esophagectomy. The value of current diagnostic tools is a matter of debate., Methods: A prospective database (2003-2013) was used to identify 266 consecutive patients with adenocarcinoma of the GEJ in order to evaluate the accuracy of endoscopic ultrasound (EUS) and computed tomography (CT) regarding tumor localization according to Siewert, nodal status and its consequences on treatment strategy., Results: Overall accuracy in determining tumor localization was 73% for endoscopy/EUS and 61% for CT (p = 0.018). With endoscopy/EUS, the accuracy was 97%, 66% and 75% respectively for type I, II and III. With CT this was respectively 69%, 57% and 80%. The overall accuracy for determining N-status (N0/N+) per patient was 75% for EUS and 71% for CT. Accuracy for determining a positive nodal station in patients without neoadjuvant therapy was 77% for EUS and 71% for CT (p = 0.001). Accuracy for detecting positive upper mediastinal nodes was 80-92%, whereas for peritumoral and abdominal nodes this was 50-80% in both EUS and CT. In 8/266 patients (3%) the type of surgery changed due to intraoperative findings. A radical resection was performed in 233 patients (88%)., Conclusions: Despite the suboptimal accuracy of determining tumor localization with EUS and CT, in only a small number of patients an intraoperative change of surgical treatment was needed. EUS is superior to CT in determining nodal status and tumor localization in GEJ tumors., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Purpose: Long-term results of inguinal hernia repair with the Prolene Hernia System (PHS) in our regional training hospital were retrospectively analysed. Research was conducted in an identical cohort of patients previously investigated for short-term results., Methods: One-hundred and fifty-eight patients (217 inguinal hernias) treated with the PHS were traced and included. Patients were invited to visit the outpatient clinic for a brief history, physical examination and ultrasound. A quality of life questionnaire was completed by all patients. The primary endpoint was recurrence rate. Testis atrophy, chronic pain and hypaesthesia were secondary endpoints., Results: The mean age of the population (n = 187) was 62.2 years (range 28-92), with a male:female ratio of 15:1 (175:12). The median follow-up was 5.5 years (range 3.9-6.8). One-hundred and forty-five patients visited the outpatient clinic, while 13 patients were included by telephone interview. Twenty-one patients died during follow-up and eight others were lost to follow-up. The resulting follow-up rate was 85% (158/187). In our initial study, we found four recurrences (1.8%) and seven patients with persisting pain (3.2%) after 32 months. During current follow-up, five patients were diagnosed with recurrent herniation (2.3%, 5/217) and only four patients (1.8%) suffered from persisting pain. Three patients (1.4%) were diagnosed with testicular atrophy, while ten patients (4.4%) experienced hypaesthesia., Conclusion: In a regional training hospital, the recurrence rate and long-term complications of patients treated for inguinal hernia with the PHS are acceptable after a follow-up of 5.5 years. The number of patients experiencing persistent pain seems to decrease over time.
