The main hepatic lesion induced by preoperative FU/oxaliplatin chemotherapy in patients with CLM is vascular and not steatosis. Detailed pathologic analysis determined that the most severe vascular lesions are associated with increased intraoperative transfusions. The risk for other postoperative complications is related to the duration of preoperative chemotherapy administration.

Background and Aims: Temporary single, fully covered self-expanding metal stent (FCSEMS) placement for benign biliary strictures (BBSs) associated with chronic pancreatitis (CP) may require fewer interventions than endotherapy with multiple plastic stents and may carry less morbidity than biliary diversion surgery. This study aimed to assess long-term outcomes in CP-associated BBSs after FCSEMS placement and removal. Methods:In this open-label, multinational, prospective study, subjects with CP and a BBS treated with FCSEMS placement with scheduled removal at 10 to 12 months were followed for 5 years after FCSEMS indwell. Kaplan-Meier analyses assessed BBS resolution and cumulative probability of freedom from recurrent stent placement to 5 years after FCSEMS indwell.Results: One hundred eighteen patients were eligible for FCSEMS removal. At a median of 58 months (interquartile range, 44-64) post-FCSEMS indwell, the probability of remaining stent-free was 61.6% (95% confidence interval [CI], 52.5%-70.7%). In 94 patients whose BBSs resolved at the end of FCSEMS indwell, the probability of remaining stent-free 5 years later was 77.4% (95% CI, 68.4%-86.4%). Serious stent-related adverse events occurred in 27 of 118 patients (22.9%); all resolved with medical therapy or repeated endoscopy. Multivariate analysis identified severe CP (hazard ratio, 2.4; 95% CI, 1.0-5.6; P Z .046) and longer stricture length (hazard ratio, 1.2; 95% CI, 1.0-1.4; P Z .022) as predictors of stricture recurrence. Conclusion:In patients with symptomatic BBSs secondary to CP, 5 years after placement of a single FCSEMS intended for 10 to 12 months indwell, more than 60% remained asymptomatic and stent-free with an acceptable safety profile. Temporary placement of a single FCSEMS may be considered as first-line treatment for patients with CP and BBSs. (Clinical trial registration number: NCT 01014390.)

Treatment of post-transplant biliary stenosis using a Wallstent is a valuable option for delaying or avoiding surgery in up to 70% of patients. Proximal stenosis can be treated in the same manner in selected patients with major comorbidities.

Compared with cross-sectional pre-operative imaging, IOUS is still superior for the detection of HT and the planning of surgery. IOUS remains recommended as a routine procedure in patients having a hepatic resection in the era of modern pre-operative imaging.
