The purpose of this study wa s to examine the usability and reliability of ultrasonography in the evaluation of the lacrimal drainage system. Observational cohort study. A prospective study was conducted at a single institution. We performed ultrasound examinations on 17 patients with epiphora before and after surgery, and on 17 asymptomatic volun teers, to visualize and evaluate the anatomic and functional condition or pathol ogic abnormalities of the LDS.Echographic evaluation of the LDS was possible in all individuals. Pathologic abnormalities (canaliculitis, diverticulitis, concre tion, or dilation of the lacrimal sac, and reduced functionality of the orbicula r muscle and/or lacrimal sac pump) could be well demonstrated. In the postsurgic al course, functional patency of the dacryocystorhinostomy opening could be veri fied in all cases. Sonography of the LDS appears to represent a reliable diagnos tic technique supplementary to clinical tests in the presurgical and postsurgica l examination of patients with epiphora. Pathologic abnormalities that may not b e apparent in routine X ray dacryocystography can be demonstrated with ultrasou nd techniques. Patients also benefit from the avoidance of exposure to ionizing radiation. However, ultrasound is not suitable for imaging the lower part of the lacrimal sac and the lacrimal duct because of the presence of overlying bony st ructures.展开更多

The data on 50 children who underwent VATS PDA ligation since 1995 were collected prospectively. Results: All patients survived. Ductal bleeding requiring sutures with patches occurred once in the open surgery group. Two patients in the VATS group underwent immediate rethoracoscopy and clipping because of residual ductal flow in the postoperative echocardiography. Complications in the VATS group included 6 (12%) recurrent laryngeal nerve injuries (3 transient) and 2 chylothoraces. One patient in each group underwent open reoperation because of residual ductal flow 1 year after the initial operation. The operative time,duration of recovery room/neonatal intensive care unit care,duration of pleural drainage, and length of hospital stay were significantly shorter in the VATS group. Conclusions: VATSPDA ligation gave results equal to traditional open surgery with a shorter operative time, faster recovery, and shorter hospital stay. More complications, especially recurrent laryngeal nerve injuries, occurred in the VATS group.展开更多
