Early Removal of the Prophylactic Drain After Distal Gastrectomy : Results of a Randomized Controlled Study.

Background: The optimal timing of the drain removal after gastrectomy has been unclear. The aim of this prospective randomized controlled study was to assess the optimal timing of removal of prophylactic drains after distal gastrectomy (DG) or pylorus-preserving gastrectomy (PPG). Methods: All patients undergoing DG or PPG for gastric cancer were eligible for this study. The exclusion criteria were combined organ resection, the use of postoperative anticoagulant therapy, intraoperative injury of other organs and anastomotic problems. Just after the operation, the eligible patients were randomly assigned to either the early removal group (n=50), where the drain was removed in the morning of the postoperative day (POD) 1, or the control group (n=50), where the drain was removed on POD 3 or later. We compared the surgical outcomes between the groups. Results: The rate of overall postoperative complications was 18% in the early removal group and 18% in the control group, with no significant difference between the groups. The severity of complications was also similar between the groups. There were no significant differences between the groups with regard to the postoperative recovery, pain or the length of the postoperative hospital stay. Conclusions: The present study demonstrated the safety and feasibility of the early removal of prophylactic drains in selected patients undergoing DG or PPG for gastric cancer

High-Resolution Imaging of the Retinal Nerve Fiber Layer in Normal Eyes Using Adaptive Optics Scanning Laser Ophthalmoscopy

To conduct high-resolution imaging of the retinal nerve fiber layer (RNFL) in normal eyes using adaptive optics scanning laser ophthalmoscopy (AO-SLO).AO-SLO images were obtained in 20 normal eyes at multiple locations in the posterior polar area and a circular path with a 3-4-mm diameter around the optic disc. For each eye, images focused on the RNFL were recorded and a montage of AO-SLO images was created.AO-SLO images for all eyes showed many hyperreflective bundles in the RNFL. Hyperreflective bundles above or below the fovea were seen in an arch from the temporal periphery on either side of a horizontal dividing line to the optic disc. The dark lines among the hyperreflective bundles were narrower around the optic disc compared with those in the temporal raphe. The hyperreflective bundles corresponded with the direction of the striations on SLO red-free images. The resolution and contrast of the bundles were much higher in AO-SLO images than in red-free fundus photography or SLO red-free images. The mean hyperreflective bundle width around the optic disc had a double-humped shape; the bundles at the temporal and nasal sides of the optic disc were narrower than those above and below the optic disc (P<0.001). RNFL thickness obtained by optical coherence tomography correlated with the hyperreflective bundle widths on AO-SLO (P<0.001)AO-SLO revealed hyperreflective bundles and dark lines in the RNFL, believed to be retinal nerve fiber bundles and Müller cell septa. The widths of the nerve fiber bundles appear to be proportional to the RNFL thickness at equivalent distances from the optic disc
