regular or low molecular heparin. Duration of hospitalization, bleeding complications, and need for surgery and blood transfu- sion where analyzed. Results: Average length of hospitalization was 7.5 days. Bleeding complication rate was 8.6%. One patient (4.3%) developed acute intraluminal postoperative hemorrhage, required blood transfusion and was managed conservatively. Another patient (4.3%) devel- oped intra-abdominal bleeding requiring blood transfusions and re-exploration to drain an infected hematoma. There were no deaths in this series. Conclusion: Bariatric surgery in patients on chronic anticoagula- tion is safe. However, the frequency of postoperative bleeding requiring blood transfusion and reoperation is higher than in the regular morbidly obese population. PII: S1550-7289(06)00450-3 P108. OUTPATIENT OPEN GASTRIC BYPASS SURGERY. David Syn, MD, David E. Mangold, MD, Allison A. Cobb, NP, Covenant Medical Center, Lubbock, TX. Background: Laparoscopic gastric bypass surgery has become synonymous with minimally invasive bariatric surgery leading to shorter hospital length of stays, however, similar if not better results can be achieved with open gastric bypass surgery when attention is given to reduction of incision size and adequate anal- gesia. Methods: From June 2005 to November 2005, 75 consecutive primary open gastric bypass procedures were performed by a single surgeon. Average incision length was 10cm. Average oper- ative time was 65 minutes. Rectus sheath block with 0.25% Mar- caine was used in all patients. External pain pump with dual catheters tunneled into bilateral rectus sheaths delivering 2cc/h of 0.25% Marcaine for 72hrs post-operatively was placed in all pa- tients. Intravenous Ketorolac was given peri-operatively. Patients were discharged on oral hydrocodone. Average age was 43.1 years. 89% were females. Average BMI was 54.5 kg/m 2 . Average number of life-threatening co-morbidities per patient was 2.1. Results: 64 of 74 patients were discharged at 24 hours post surgery. 2 of 74 patients were discharged within 12 hours of surgery. Average length of stay was 1.2 days. There were no anastomotic leaks or deaths. One patient was readmitted within 30 days. The most common post-operative complication was seroma, 7 of 74. The second most common post-operative complication was wound infection, 3 of 74. Conclusion: Open gastric bypass surgery, when done with atten- tion to reducing incision length and controlling post-operative pain, can yield results similar to if not better than laparoscopic surgery and in select patients can be done as same-day surgery.

Nguyen, MD, University of California Irvine Medical Center, Orange, CA. Background: The outcome of laparoscopic adjustable gastric banding (Lap-Band) has only been examined within single insti- tutional experience. No study has examined the outcome of lapa- roscopic restrictive bariatric procedure at a national level due to the lack of specific ICD-9 procedure codes. The University Health- System Consortium (UHC) contains data from all major teaching hospitals in the US and recently added specific procedural codes for lap-Band and laparoscopic gastroplasty. The aim of this study was to examine the utilization and outcome of laparoscopic re- strictive procedures performed at academic medical centers. Methods: Clinical data of 11,073 patients who underwent bariatric surgery between 2004 and 2005 were obtained from the UHC database. A total of 1,412 patients (13%) had laparoscopic gastric restrictive procedures. Of these, 960 patients underwent Lap-Band (68%) and 452 patients had laparoscopic gastroplasty. The data were reviewed for demographics, co-morbidities, length of hospi- tal stay, postoperative morbidity, 30-day readmission, and in- hospital mortality. Results: Removal of Lap-Band occurred in 0.4% and revised in 1.6% of patients. (See Table) Conclusion: Within the context of this analysis of academic centers, laparoscopic gastric restrictive procedures offer a short length of hospital stay with minimal morbidity and no mortality.

LONG-TERM QUALITY OF LIFE IMPROVEMENT AFTER LAPAROSCOPIC GASTRIC BYPASS. Jennifer G. Ginnings, RN, Christian R. Ketel, NP, MSN, Barry R. Berch, MD, Joan L. Kaiser, RN, MSN, Alfonso Torquati, MD, MSCI, William O. Richards, MD, Vanderbilt University Medical Center, Nashville, TN. Background: Quality of life (QOL) is getting attention in the medical literature. Treatment outcomes are now gauged by their effect on the QOL along with their direct effect on diseases they are targeting. Similarly, in obesity, consensus has been reached on the importance of QOL as an independent outcome measure for obesity surgery along with weight loss and co-morbidity. The aim of the study was to assess the impact of patient demographics and co-morbidities on QOL improvement after laparoscopic gastric bypass surgery. Methods: QOL was evaluated using the short-form-36 (SF-36). Forms were completed preoperatively and  2 years post-opera- tively in 100 patients (88 female, 12 male; mean age 44 years). 345 Abstracts: Poster Session 2006 / 2 (2006) 310 –347
