Fibrin sealant associated with increased body temperature and leukocytosis after laparoscopic gastric bypass.
BACKGROUND
Fibrin sealants (FSs) have been used in both open and laparoscopic bariatric surgery to decrease the anastomotic leak rate; however, conclusive evidence to recommend routine use is still lacking. We studied FS use and its effect on the clinical inflammatory response after laparoscopic Roux-en-Y gastric bypass.


METHODS
Of 474 consecutive patients scheduled to undergo laparoscopic Roux-en-Y gastric bypass, 158 were assigned to group 1 (no FS used), 158 were assigned to group 2 (FS used at the gastrojejunal anastomosis and gastric staple line), and 158 patients were assigned to group 3 (reverting back to no FS use).


RESULTS
The mean age of all patients was 40.7 years (range 18-64), and the mean body mass index was 51.9 kg/m(2) (range 36.7-107). The FS group had a statistically significant higher pulse rate (P = .001), recorded temperature (P = .001), and white blood cell count (P = .001) in the first 48 hours after surgery. The overall leak rate was 4.2% (20 of 474 cases). The mortality rate was 0% in all 3 groups. FS use had no effect on the anastomosis or staple line leak rate. An evaluation for fever of unknown origin was required in 6 patients in the FS group with no evidence of leak. Of these 6 patients, 4 had no evidence of leak on upper gastrointestinal series or computed tomography and 2 underwent surgical exploration with a subphrenic collection found but no evidence of leak intraoperatively (negative findings for pneumatic and methylene blue tests).


CONCLUSIONS
FS use in laparoscopic Roux-en-Y gastric bypass is associated with an increased clinical inflammatory response mimicking anastomotic leak. FS had no effect on the anastomotic leak rate.
