Burton; Jorge E. Urbandt, M.D.; Philip F. Caushaj, M.D.; Surgery, The Western Pennsylvania Hospital, Clinical Campus of Temple University School of Medi- cine, Pittsburgh, PA, USA. Background: Patients undergoing bariatric surgery while on an- ticoagulation are considered high risk. We describe our experience with bariatric surgery on patients on active anticoagulation. Methods: Retrospective analysis of a prospective database focus- ing on laparoscopic bariatric surgery in patients on active antico- agulation therapy. Type, duration and reason for anticoagulation, and perioperative management and complications were recorded. Results: 1400 patients underwent laparoscopic bariatric surgery between July 1999 and July 2007 in our institution. Thirty patients (2.1%) were on active anticoagulation preoperatively for cardiac and cardiovascular diseases (n=14), venous thromboembolic dis- ease (VTE) (n=12) and both cardiac and VTE (n=4). All 30 patients underwent laparoscopic procedures; RYGB (n= 27), con- version of VBG to RYGB (n=2), sleeve gastrectomy (n=1). Patients were on warfarin (n=23), warfarin and clopidogrel (n=4) and low molecular weight heparin (LMWH) (n=3). Twelve pa- tients (40%) had preoperative consultation with a hematologist. Four patients had an IVC filter prior to surgery. Thirteen of 27 patients on warfarin (48%) were bridged with LMWH. The median time for discontinuing warfarin preoperatively and resuming post- operatively was 5 and 2 days respectively. There were no mortal- ities. Six patients (20%) developed bleeding complications, one of which required surgical intervention. Five patients presented with gastrointestinal bleeding and one patient with a soft tissue hema- toma. Anticoagulation was stopped on all patients with bleeding complications and resumed after the hemoglobin was stabilized. Conclusion: Laparoscopic bariatric surgery may be safe in pa- tients requiring active anticoagulation. Bleeding complications may be higher in this group of patients. PII: S1550-7289(08)00223-2 P51. EATING BEHAVIOR PATTERNS AND WEIGHT LOSS ONE YEAR AFTER LAPAROSCOPIC BANDING SURGERY Adam B. Smith, DO 3 ; Susan F. Franks, PhD 1 ; Kathryn A. Kaiser, B.S. 1 ; Joan F.

Background: Successful weight loss with laparoscopic banding surgery (LBS) depends largely on life-long behavioral changes. The possible re-emergence of habitual eating patterns creates a risk for behavioral non-compliance. We previously reported differ- ences in eating patterns between normal weight (NW) and LBS subjects (LB) prior to LBS (T1), and their normalization 6 months post-LBS. The purpose of this study was to examine the stability of these effects on eating behavior and weight loss one-year post-LBS (T2). Methods: Subjects included 29 LB and 30 NW. All subjects completed the Eating Inventory to assess Cognitive Restraint (CR), Disinhibition (DI) and Hunger (HN) at T1. LB were retested at T2, and compared using repeated measures ANOVA. Percent excess weight loss (EWL) was calculated for LB based on pounds to achieve a BMI of 25.0. LB was split high (73.384.62%) and low (25.5713.51%) EWL at T2. Point-biserial correlations were used to determine the relationships between EWL, EI scores at T1 and T2, and change in EI scores (T2-T1). 331 Abstracts: 2008 Poster Session 2 / Surgery for Obesity and Related Diseases 4 (2008) 312–357
