Risk Factors Predicting Serious Complications With Laparoscopic Gastric Bypass Surgery
Risk Factors Predicting Serious Complications With Laparoscopic Gastric Bypass Surgery
The rate of serious complications are relatively low in bariatric surgery today, but still 3-4 % will suffer from a serious complication. There are factors known before the surgery or during the operation that are likely to increase the risk for a serious complication. If the investigators are aware of these we can optimize the patients risk factors prior to the operation or at least increase the awareness of the increased risk in some patients given the presence of risk factors.
Data is collected prospectively to the Scandinavian Obesity Surgery Registry. Today all 44 clinics performing bariatric surgery in Sweden submits data on baseline characteristics, operational data and data from a 30 days, 1 year, 2 years and 5 years follow up for all patients. The database is compared annually to the Swedish civil registry to cover all mortality.
From the database we will identify patients who underwent a bariatric procedure between May 1st 2007 and September 30th 2012. Patients undergoing other bariatric procedures than laparoscopic gastric bypass or revisional surgery will be excluded.
The data will be analyzed with "Chi-2" test, logarithmic regression, linear regression or t-test when appropriate. Odds ratio will be calculated.
Inclusion Criteria:

Exclusion Criteria:
Undergoing other bariatric procedure than laparoscopic gastric bypass. Revisional surgery is excluded.
