Factors associated with readmission after laparoscopic gastric bypass surgery.
ABSTRACT BACKGROUND: Studies have demonstrated that laparoscopic Roux-en-Y gastric bypass (RYGB) is associated with the greatest readmission rate among bariatric surgeries. Some readmissions might be avoidable. We sought to evaluate the risk factors for readmission in a high-volume bariatric surgery program at a university hospital in the United States. METHODS: We performed a retrospective review of prospectively maintained data. Patients readmitted within 30 days of laparoscopic RYGB were randomly matched to control patients who had undergone RYGB in the same year but were not readmitted. The readmissions were categorized as technical complications (leak), wound infections, or malaise (nausea, dehydration, or benign abdominal pain). Patients with a wound infection treated in an outpatient setting were also evaluated and compared with the patients admitted with a wound infection. RESULTS: From July 2002 to July 2008, 450 patients underwent RYGB. Readmission occurred in 42 patients (9%). Of these 42 patients, 6 were admitted with wound infections (14%), 18 (43%) with malaise, and 18 (43%) with technical complications. The patients admitted with wound infections were similar to their controls, except that they were more likely to have publicly funded insurance (Medicare or Medicaid) and more likely to present for medical attention to the emergency department after clinic hours. The patients admitted with malaise reported a greater pain score at discharge and were also more likely to have public health insurance than controls. The patients with technical complications did not differ from the control patients in any examined variable. CONCLUSIONS: Patients with publicly funded insurance are at increased risk of readmission after RYGB. Outpatient mechanisms for managing wound infections and malaise might result in decreased readmissions.

ABSTRACT: The increasing incidence of bariatric/metabolic surgery has brought concerns about the short- and long-term safety of this definitive treatment option. Many multicenter, large cohort studies of outcomes after bariatric surgery have been performed worldwide. Due to innovation in surgical methods and postoperative management programs in this field, there is a continuous improvement of outcomes related to safety. Many systemic and surgical complications after bariatric surgery have been reported, and late complications after gastric banding procedure are becoming issues as long-term follow-up studies are being performed. These databases utilize both clinical and administrative data methods. They may report in hospital only 30 or 90 day complication rates. Perioperative mortality in the past has been reported in as many as 1.5 to 2 % of bariatric surgical cases. Most recently this mortality has been reduced to 0.04-0.3 % from registries involving many thousands of patients. Complications are defined variably. Serious complications reportedly occur in 1-4 % of patients. In malabsorptive procedures, nutritional and micronutrient support is important because they frequently cause nutritional and metabolic problems long after surgery. Also, procedure-related complications such as intestinal obstruction and anastomotic stricture should be monitored after gastric bypass. This review refers to such adverse events which can threaten patient safety after bariatric surgery.Current Atherosclerosis Reports 10/2012; · 2.92 Impact Factor

ABSTRACT: Laparoscopic gastric bypass (LGBP) is the most common bariatric procedure worldwide. The gastrojejunostomy can be stapled with a circular or linear stapler, each with their own specific advantages. We have evaluated differences in postoperative complications between the two techniques. We studied operative data and postoperative complications in 560 patients (79.8 % females, median age 42, BMI 42.5) operated with LGBP between 2008 and 2012 at our center. The gastrojejunostomy was initially performed using a circular stapler (CS) in 288 patients and later by linear stapler (LS) in 272. Complications, operative time, and length of stay were retrieved from our database. The risk of developing a port site infection was evaluated with multivariate logistic regression. Port site infections were more common with CS than LS, 5.2 and 0.4 %, respectively (p < 0.01). Multivariate analysis demonstrated CS to be an independent risk factor for port site infections (OR 16.3 (2.09-126), p < 0.01), as well as for stomal ulcers (OR 10.1, 1.15-89, p = 0.04). Major postoperative complications remained unchanged (anastomotic leak 1.0 vs. 1.1 %, abscess 0.7 vs. 0.4 %), while operative time and length of stay were found to be shorter using the LS (122 vs. 83 min, p < 0.001 and 4 vs. 3 days, p < 0.001). The linear stapled technique yielded lower incidence of port site infections, probably by avoiding the passage of a contaminated circular stapler through the abdominal wall. No difference in major complications was seen, but operative time was shorter using a linear stapler instead of a circular stapler.Obesity Surgery 12/2013; · 3.10 Impact Factor

ABSTRACT: Millions of patients will be added to Medicaid programs throughout the country due to expansion driven by the Affordable Care Act. Since 90 % of state Medicaid programs cover bariatric surgery, the outcomes of Medicaid patients will be important to study. We performed a retrospective analysis to compare outcomes between Medicaid and non-Medicaid bariatric surgery patients over a two-year period. All patients who underwent a laparoscopic Roux-en-Y gastric bypass at The Ohio State University Medical Center from January 2008-April 2011 were identified. Of these 609 patients, 30 Medicaid patients were identified and compared to 90 randomly selected non-Medicaid patients (1:3 case-control). Preoperative data and postoperative outcome data (weight loss, comorbidity resolution, complications, and mortality) were obtained from electronic medical records. Descriptive statistical analyses were performed to compare categorical and continuous variables. Medicaid patients had a significantly higher average BMI (58.4 vs. 49.5; p < 0.001) and higher rates of comorbidities. Over a 90-day postoperative period, Medicaid patients experienced a higher wound complication rate (20.0 vs. 5.6 %; p = 0.03) and visited the ER more frequently (33.3 vs. 10.0 %; p = 0.007) but had similar rates of medical complications compared to non-Medicaid patients. The Medicaid cohort lost 52.1 % of its excess body weight vs. 64.6 % for the non-Medicaid cohort (p = 0.02) over a two-year period. There were no significant differences in comorbidity resolution, anastomotic complications, or mortality after 2 years of follow-up. Despite being a higher risk cohort, Medicaid patients undergoing laparoscopic Roux-en-Y gastric bypass had similar long-term outcomes compared to non-Medicaid patients.Obesity Surgery 03/2014; · 3.10 Impact Factor
