Background: Patient information is critical in shared decision-making and patient-centred management for neuroendocrine tumours (NETs). Most adults search the internet for health issues, with over half considering such information to be credible. Therefore, we evaluated the quality of online information on NETs. Methods: Searching for “Neuroendocrine Tumours”, the top 20 websites from Google and top 10 from Yahoo and Bing were identified. Open-access websites written in English were included. Websites indicated as advertisements or directed towards healthcare providers were excluded. Each website was evaluated using the JAMA benchmarks, DISCERN instrument, and the Health on the Internet (HONCode) seal by two independent reviewers. Results: We included 16 unique websites after removing duplicates. Four were education pages from healthcare institutions, 10 were Cancer Society pages, and 2 were general information pages. The average score for JAMA benchmarks was 2.3, with 19% of websites receiving the highest score of 4. Specifically, 31% met the benchmark for authorship, 69% for attribution, 94% for disclosure, and 44% for currency. The average score for the DISCERN instrument was 46.5, with no website achieving the maximum of 80 points. The HONCode seal was present in 3 out of 16 websites (18%). Conclusions: We identified major issues with the quality of online information for NETs using validated instruments. The majority of websites identified through common search engines are low-quality. Patients should be informed of the limited quality of online information on NETs. High-quality online information is needed to ensure that patients can avoid misinformation and actively participate in their care.

Abstract This manuscript is the result of the North American Neuroendocrine Tumor Society consensus conference on the surgical management of pancreatic neuroendocrine tumors from July 19 to 20, 2018. The group reviewed a series of questions of specific interest to surgeons taking care of patients with pancreatic neuroendocrine tumors, and for each, the available literature was reviewed. What follows are these reviews for each question followed by recommendations of the panel.

AbstractBackgroundPost‐operative pain management is a critical component of perioperative care. Patients at risk of poorly controlled post‐operative pain may benefit from early measures to optimize pain management. We sought to identify risk factors for post‐operative pain and opioid consumption in patients undergoing liver resection.MethodsThis is a multi‐institutional prospective nested cohort study of patients undergoing open liver resection. Opioid consumption and pain scores were collected following surgery. To estimate the effects of patient factors on opioid consumption (oral morphine equivalents—OME) and on pain scores (NRS‐11), we used generalized linear models and multivariable linear regression model, respectively.ResultsOne hundred and fifty‐three patients who underwent open liver resection between 2013 and 2016 were included in the study. The mean patient age was 62.2 years, and 43.3% were female. Younger patients were significantly more likely to use more opioids in the early post‐operative period (16.7 OME/10 years, p < 0.001). Patient factors that were significantly associated with increased NRS‐11 pain scores also included younger patient age (difference in pain score of 0.3/10 years with cough and 0.2/10 years at rest, p < 0.01 for both) as well as a history of analgesic use (difference in pain score of 0.9 with cough and 0.6 at rest, p < 0.01 and p = 0.07, respectively).ConclusionYounger patients and those with a history of analgesic use are more likely to report higher post‐operative pain and require higher doses of opioids. Early identification of these patients, and measures to better manage their pain, may contribute to optimal perioperative care.

AbstractBackgroundThe study aims were to model acute pain intensity and opioid consumption trajectories up to 72 hr after open hepatic resection, identify predictors of trajectory membership and examine the association between trajectory memberships and 6‐month pain and psychological outcomes. This is a long‐term analysis of a published randomized controlled trial on the impact of medial open transversus abdominis plane catheters on post‐operative outcomes.MethodsA total of 152 patients (89 males; mean age 63.0 [range: 54–72]) completed questionnaires on pain and related characteristics pre‐operatively and 6 months post‐operatively. Total opioid use was recorded several times over a 72‐hr period while self‐reported pain intensity scores were collected multiple times until hospital discharge. Analyses were carried out using growth mixture modelling, logistic regression and general linear models.ResultsBoth pain intensity and opioid consumption showed that a four‐trajectory model best fits the data. Patients in the lowest opioid consumption trajectory were more likely to be classified in the constant mild pain intensity trajectory. Age and baseline levels of anxiety significantly predicted opioid trajectory membership while baseline depressive symptoms significantly predicted pain intensity trajectory membership. Patients in the two highest opioid consumption trajectories reported significantly higher levels of pain catastrophizing at 6 months compared to patients in the other 3 trajectories (all p < 0.05).ConclusionHigh consumption of opioids after surgery is associated with higher levels of pain catastrophizing 6 months later. Identification of patients within these trajectories may lead to the development of early interventions targeted to high risk individuals.SignificanceDifferences in initial levels of opioid consumption and rates of change in opioid consumption shortly after surgery can help predict long‐term psychological responses to pain. Identifying key characteristics associated with initial opioid consumption can lead to the development of cost‐effective early interventions targeted to high risk individuals.

Objective: Conventional management of pain following open liver resection involves intravenous, patient-controlled analgesia (IV PCA) or epidural analgesia. The objective of this trial was to assess the efficacy of a regional technique called Medial Open Transversus Abdominis Plane (MOTAP) catheter analgesia compared with IV PCA. Methods: This was a blinded, randomized, controlled parallel-arm trial conducted at 2 high-volume centers. Patients undergoing liver resection through a subcostal incision were enrolled. Using a standardized technique, 2 catheters were placed after resection: one in the plane between internal oblique and transversus abdominis and the other in the posterior rectus sheath. Patients were randomized to receive ropivacaine 0.2% (ROP) or saline (NS) through both catheters for 72 hours. All patients received IV PCA with hydromorphone as part of a multimodality analgesia program. Primary outcome was opioid use over the first 48 hours. Results: One hundred fifty-three patients were included in the analysis (71 ROP, 82 NS). Patients receiving ROP used significantly less opioid than patients with NS at 48 hours (median 39.6 mg morphine-equivalent vs 49.2 mg, P = 0.033) and at 72 hours (median 50.0 vs 66.4 mg, P = 0.046). Pain scores at rest and with coughing were significantly lower at all time points in patients who received ROP (P = 0.002). Median length of hospital stay was 5 days in patients receiving ROP and 6 days in patients who received NS (P = 0.035). There was no difference between groups in complications [ROP 20 (28.2%) vs NS 26 (31.7%), P = 0.63]. Conclusion: MOTAP catheter analgesia reduces opioid requirements, pain, and length of hospital stay compared with IV PCA following open liver resection with subcostal incisions.
