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:

 Undergoing laparoscopic gastric bypass surgery and included in the Scandinavian Obesity
 Surgery Registry

 Exclusion Criteria:

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

 Lost to follow up.
