title: Early gastrointestinal hemorrhage after laparoscopic gastric bypass.
abstract: BACKGROUND
  Early gastrointestinal (GI) hemorrhage after open gastric bypass has been infrequently reported. The aim of this study was to examine the incidence of early GI hemorrhage after laparoscopic Roux-en-Y gastric bypass (LRYGBP), its presentation, and possible treatment options.
  
  
  METHODS
  A retrospective review of 5 patients who developed early postoperative GI hemorrhage after LRYGBP was performed. The charts were reviewed for demographics, clinical presentation, diagnostic evaluation, and treatment. All patients underwent a transected LRYGBP with creation of the gastrojejunostomy anastomosis with a circular stapler and the jejunojejunostomy anastomosis with a linear stapler.
  
  
  RESULTS
  Of the 155 patients in our database who underwent LRYGBP, 5 (3.2%) developed early clinical GI hemorrhage. There were 2 males with an average age of 40 years. Clinical presentations of GI hemorrhage were hematemesis (2 patients), bright red blood per rectum (1 patient), melena (1 patient), and hypotension (1 patient). A diagnostic study (nuclear scintigraphy) was performed in only 1 of 5 patients. 3 of 5 patients were managed nonoperatively; 2 patients required fluid and blood resuscitation, and the other patient was managed without blood transfusion. The onset of hemorrhage in these 3 patients occurred 24 hours postoperatively or later. 2 of 5 patients required operative intervention for control of hemorrhage. The onset of hemorrhage or hypotension in these 2 patients occurred within 12 hours after surgery. The sites of hemorrhage were at the gastric remnant staple-lines in 1 patient and at the gastrojejunostomy and gastric remnant staple-lines in the other patient.
  
  
  CONCLUSIONS
  Early GI hemorrhage is a potential complication after transected LRYGBP. Early reoperative intervention should be performed for patients with hemodynamic instability and patients with early onset of hemorrhage after surgery.
