Background Timely surgical resection in patients with suspected or diagnosed pancreas adenocarcinoma is an essential part of care. We hypothesized that longer surgical wait time was associated with worse oncologic outcomes. Methods A retrospective cohort of patients (N = 144) with resectable pancreas adenocarcinoma was divided into four wait time groups ( 12 weeks), defined from the time of diagnosis on cross-sectional imaging. Overall and recurrence-free survival were analyzed using the Kaplan–Meier method and Cox proportional hazards regression. A higher rate of conversion to palliative bypass in patients waiting over 4 weeks was observed and further analyzed using post-hoc multivariate regression. Results On multivariable analysis, longer wait time was associated with improved overall (HR 0.49, 95% CI: 0.28–0.85) and recurrence-free survival (HR 0.29, 95% CI: 0.15–0.56) in >12 weeks compared to Conclusion Wait time over 8 weeks was associated with a higher rate of palliative bypass. There was an improvement in overall and recurrence-free survival in patients who waited over 12 weeks, likely due to selection bias.

Objective To compare the efficacy and safety of patient-controlled analgesia (PCA) to epidural analgesia in adults undergoing open hepatic resection. Background Effective pain management in patients undergoing open hepatic resection is often achieved with epidural analgesia. However, associated risks have prompted investigation of alternative analgesic methods in this patient population. Methods A comprehensive systematic literature review via Medline, Embase, and the Cochrane databases from inception until December 2, 2017 was conducted, followed by meta-analysis. Abstract and full-text screening, data extraction, and quality assessment were conducted by 2 investigators. Odds ratios (OR), mean differences (MD), and 95% confidence intervals were calculated using RevMan 5.3. Results Four randomized controlled trials with 278 patients were identified. All studies compared the use of PCA to epidural, with differing regimens. Pooled MD and 95% confidence interval for pain score were higher for PCA at rest 24 hours postoperatively (0.59 [0.30, 0.88]), and with movement at 48 hours postoperatively (0.95 [0.31, 1.60]. Pooled MD for hospital length of stay was 1.23 days (-2.72, 5.19). Pooled OR was 0.68 (0.36, 1.3) and 0.24 (0.04, 1.36) for overall and analgesia-related complications, respectively. Need for blood transfusion had a pooled OR of 1.14 (0.31, 4.18). Conclusions Epidural analgesia was observed to be superior to PCA for pain control in patients undergoing open hepatic resection, with no significant difference in hospital length of stay, complications, or transfusion requirements. Thus, epidural analgesia should be the preferred method for the management of postoperative pain in this patient population.
