The aim of the study was to investigate the impact of Nissen-Rossetti fundoplication on the blood flow in the microcirculation of the gastric fundus.Material and methods. Eight patients undergoing Nissen-Rossetti fundoplication were included in the study. Perfusion in the gastric fundus was measured intraoperatively with laser Doppler flowmetry. An adhesive, flat, silicon probe was attached to the serosa in the same anatomical location during every measurement. Microcirculatory blood flow was recorded before and after fundoplication without ligation and division of the short gastric vessels.Results. In each patient, fundoplication led to increases in resting perfusion. Hyperperfusion was evoked by two mechanisms: increase in average blood flow and increase in vasomotion's amplitude and frequency.Conclusions. Fundoplication constitutes a new distribution of blood flow in the microcirculation of the gastric fundus, irrespective of its indication as a treatment of reflux disease or a supplement to cardiomyotomy in patients with achalasia. The procedure, when correctly performed, leads to local reactive hyperemia. Decreases in fundal perfusion suggest that the fundoplication wrap was created under excessive tension and may lead to dysphagia and local ischemia with consequences on motility of the lower esophagus. Thus, the assessment of change in perfusion of the gastric fundus after fundoplication might be a valuable tool in the routine quality control for appropriate performance of the fundoplication wrap.
