RESUMEN
As the number of patients requiring operation for peptic ulcer disease (PUD) declines, presumed contemporary ulcer etiology has largely been derived from medically treated patients not subjected to surgery. The purpose of this study was to examine the specific causes of PUD in patients requiring surgery. Our Acute Care Surgical Service registry was reviewed for patients operated on for complications of PUD from 2004 to 2009. Emphasis was placed on individual etiologic factors for PUD. There were 128 patients (52% male, 81% white) who underwent emergency operation including: simple patch closure (n = 61, 48%); gastric resection (n = 22, 17%); gastric resection with vagotomy (n = 21, 16%); vagotomy and pyloroplasty (n = 18, 14%); or other procedures (n = 6, 5%). Complications necessitating operation were perforation (n = 79, 62%); bleeding (n = 29, 23%); obstruction (n = 12, 9%); and intractability (n = 8, 6%). Perioperative mortality was 12.5 per cent. Risk factors for PUD included tobacco use (50%), alcohol abuse (34%), and steroids (21%). Nonsteroidal anti-inflammatory use was confirmed in 68 (53%) patients. Of the 128 patients, 82 (64%) were tested for Helicobacter pylori, 33 (40%) of which were positive and 49 (60%) negative. Helicobacter pylori, thus, was the confirmed ulcer etiology in only 26 per cent of cases. Unlike contemporary series of medically treated PUD, Helicobacter pylori may not be the predominant etiologic factor in patients who experience complications requiring surgery. A "traditional" surgical approach with liberal use of vagotomy, not antibiotic triple therapy, may well be the preferred treatment consideration in such cases.

BACKGROUND: Up to 50% of AV fistulas fail to mature, primarily because of problems with fistula cannulation. Fistula elevation procedure (FEP) is a simple superficialization procedure where the fistula is surgically exposed, mobilized, and elevated into a more superficial position for the purpose of facilitating AV fistula cannulation. The purpose of this study is to review use of FEP as an adjunct to fistula maturation. STUDY DESIGN: Two hundred ninety-five FEPs were performed between February 1999 and December 2005. FEP was performed if the fistula was considered too deep to cannulate or if nurses were unable to cannulate the fistula. Kaplan-Meier life-table analysis was used to determine patency and for a subanalysis by location of FEP performed (172 brachial-cephalic, 70 brachial-basilic, 46 radial-cephalic, 7 superficial femoral vein). Survival curves were compared using log-rank test. RESULTS: Functional primary patency rates for patients undergoing an adjunctive FEP were 73% at 6 months, 60% at 1 year, and 46% at 2 years. Secondary functional patency rates were 81% at 6 months, 71% at 1 year, and 59% at 2 years. There was no statistical significance in any outcomes based on anatomic site of elevation. CONCLUSIONS: AV fistulas that might otherwise have been abandoned because of excessive depth or tortuosity can be successfully salvaged by an adjunctive FEP and achieve satisfactory longterm functional patency. FEP is a valuable adjunct to AV fistula creation, which will enhance fistula maturation rates.
