Abstract
BACKGROUND: While there are various techniques to create the gastrojejunostomy during a laparoscopic Roux-en-Y gastric bypass (LRYGB), many surgeons prefer using a circular stapler. One drawback of this method, however, is the higher incidence of surgical site infections (SSIs). To investigate the effect of a dual ring wound protector on SSIs during LRYGB. METHODS: In April 2016, our bariatric surgical group implemented an intervention whereby a dual ring wound protector in conjunction with a conical EEA stapler introducer was used when creating the gastrojejunostomy. SSIs from pre- and post-intervention were compared using Fisher's exact test. Only LRYGBs performed with a circular stapler were included in our analysis. Student's t test and χ2 were used to compare pre- and post-intervention groups with respect to demographics and co-morbidities. RESULTS:Between April 2015 and January 31st, 2017, our surgeons performed 158 LRYGBs using a circular stapler for the gastrojejunostomy. There were 84 patients (53%) in the pre-intervention group and 74 (47%) in the post-intervention group. The pre- and post-intervention groups were not statistically different. The SSI rate for the pre-intervention group was 9.5% while the SSI rate was 1.35% in the post-intervention group (p = 0.0371). The use of a dual ring wound protector for LRYGBs with circular stapled gastrojejunostomy was associated with an 86% relative risk reduction in SSIs. CONCLUSION: Using a dual ring wound protector in conjunction with a conical EEA introducer for LRYGBs with circular stapled gastrojejunostomy significantly decreased SSIs.
