Abstract
AIM: We aimed to evaluate the possible effects of dissecting gastric breves (GB) during the Laparoscopic Nissen Fundoplication (LNF) on the gastric fundus and splenic circulation using dynamic Magnetic Resonance Imaging (MRI). METHODS: In total 14 patients with gastroesophageal reflux disease (GERD) that was diagnosed with esophagogastroduodenoscopy and 24 - hour PH monitorization and undergoing LNF surgery were included. All patients underwent LNF surgery between October 2006 and March 2010. All patients were evaluated regarding gastric fundus and splenic circulation one week before and 15 days after the surgery with dynamic MRI. Alteration of the signal intensity before and after surgery was used to assess gastric fundus and splenic circulation. RESULTS: We detected a significant decrease in DeMeester score before and after surgery (p < 0.001). There were no statistical differences between preoperative and postoperative dynamic MRI measurements of the spleen, anterior wall measurements, posterior wall measurements in different MRI phases (Bonferroni corrected p < 0.01). Postoperative measurements of anterior and posterior gastric wall measurements were comparable (Bonferroni corrected p < 0.0033). CONCLUSIONS: We did not detect any significant differences in the abovementioned tissues regarding perfusion.
