Keloid Intralesional Excision Reduces Recurrence: A Meta-analytic Study of the Available Literature on 608 Keloids.

Background: The objective of this meta-analysis was to examine the effectiveness of keloid intralesional excision (KILE) in preventing recurrence. Treatment of keloids using surgical excision alone leads to high rates of recurrence. To date, there are no widely accepted guidelines for keloid treatment, and a multitude of adjunctive therapies are used to reduce recurrence. Despite these efforts, recurrence remains high. In this study, we conducted a meta-analysis of the existing literature on KILE to determine its role in recurrence reduction. Methods: A literature review using PubMed, Scopus, and Web of Science databases was performed. Two authors independently evaluated studies for eligibility. Incidence of keloid recurrence was recorded, and a comprehensive meta-analysis was performed to assess the pooled keloid recurrence rate, as well as the effect of additional therapies. Results: Twenty-two studies evaluating intralesional excision of 608 keloids were included in the study. Average time to follow-up was 19.2 months (range 6-35 months). A meta-analysis of proportions was conducted, demonstrating a pooled recurrence rate of 13% (95% confidence interval, 9%-16%). There was no evidence that using therapies in addition to KILE had a significant effect on the overall pooled recurrence rate. Conclusions: A meta-analysis of 608 keloids shows that KILE is an effective technique in preventing keloid recurrence, with a pooled recurrence rate of 13% compared with previously reported rates of 45%-100% after complete excision. Although there are no standard guidelines for keloid treatment, our meta-analysis shows that KILE is promising in recurrence reduction.

When Is It Safe to Proceed With Pancreaticoduodenectomy Without Biliary Decompression?

BACKGROUND: An absolute bilirubin level where preoperative biliary decompression (PBD) is indicated before pancreaticoduodenectomy has been elusive. Our goal was to identify a total bilirubin level whereby biliary decompression provides clear benefit, despite associated expenses and potential complications. MATERIALS AND METHODS: We reviewed a prospectively collected database of patients undergoing pancreaticoduodenectomy at the Vidant Medical Center between 2007 and 2016. Patients were arbitrarily subdivided into 3 groups based on presenting bilirubin level (≤10 mg/dL, 10.1-14.9 mg/dL, and ≥15 mg/dL) to determine the presence of overall complications, severe complications (Clavien-Dindo classification ≥3), prolonged length of stay (>1 SD), readmissions, or mortality. RESULTS: Common bile duct stenting independently predicted a higher incidence of complications in patients presenting with bilirubin ≤10 mg/dL (P = .03) vs. those patients going directly to surgery. No differences were observed for patients with bilirubin between 10.1 mg/dL and 14.9 mg/dL. Biliary decompression in patients with bilirubin ≥15 mg/dL independently predicted fewer overall (73.8% vs. 100%, P = .0082) and less severe complications (14.3% vs. 44.5%, P = .03) and lower readmission rates (15.8% vs. 55.6%, P = .03) vs. those going directly to surgery. Patients not undergoing biliary decompression underwent pancreaticoduodenectomy sooner than those decompressed (4.7 days vs. 17.2 days, P = .01). DISCUSSION: All patients presenting with bilirubin ≥15 mg/dL should undergo PBD, while those with bilirubin ≤10 mg/dL should forego stent placement to avoid stent-related complications. The decision to stent between 10.1 and 14.9 mg/dL should be made on a case-by-case basis keeping in mind timeliness to definitive cancer treatment.

Examining Hemodialysis Reliable Outflow catheter performance and cost in hemodialysis access.

BACKGROUND: The Hemodialysis Reliable Outflow (HeRO) vascular access device is a hybrid polytetrafluoroethylene graft-stent construct designed to address central venous occlusive disease. Although initial experience has demonstrated excellent mid-term patency rates, subsequent studies have led to external validity questions. The purpose of this study was to examine a single center experience with this vascular access device in challenging access cases with associated costs. METHODS: A retrospective study representing the authors' cumulative HeRO vascular access device experience was undertaken. The primary endpoint was graft failure or death, with secondary endpoints including secondary intervention rates and cost. RESULTS: Forty-one patients with 15,579 HeRO days and a mean of 12.7 ± 1.5 mo with the vascular access device were available for analysis. Secondary patency was 81.6% at 6 mo and 53.7% at 12 mo. The reintervention rate was 2.84 procedures per HeRO vascular access device year. Associated HeRO costs related to subsequent procedures were estimated at $34,713.63 per patient/y. CONCLUSIONS: These data on the patency and primary outcome data diverge significantly from initial multicenter studies and represent a real-world application of this technology. It is costly to maintain patency. Use of HeRO vascular access devices should be judicious with outcome expectations reduced.
