[Analysis of unplanned reoperation following vitreoretinal surgery]

Abstract

Objective: To determine the incidence of unplanned reoperation following vitreoretinal surgery and identify the reasons for unplanned reoperations. Methods: Case records of all patients undergoing vitreoretinal surgery at Peking Union Medical College Hospital between June 2014 and June 2017 were reviewed to determine the incidence of unplanned reoperations during the primary admission and within 90 days following vitreoretinal surgery. Results: A total of 3 356 case records were reviewed. During the primary admission, 97 times of unplanned reoperation occurred in 81 cases [45 males and 36 females, aged (47.3±16.8) years].The incidence of unplanned reoperation was 2.4% (81/3 356). The most common primary diseases were retinal detachment (25 cases, 30.9%), proliferative diabetic retinopathy (23 cases, 28.4%) and silicone oil filled eye (17 cases, 21.0%). The most common reasons for unplanned reoperation were new onset or recurrent retinal detachment (33 times, 34.0%), increased intraocular pressure (23 times, 23.7%), as well as hyphema and inflammation (16 times, 16.5%). The percentages of the primary diseases and reasons for unplanned reoperation within 90 days following vitreoretinal surgery were not significantly different when compared with those during the primary admission. Desired results could be achieved in all cases after unplanned reoperation. Conclusions: The primary diseases of unplanned reoperation for vitreoretinal surgery are complicated retinal detachment, diabetic retinopathy and silicone oil filled eyes. New onset or recurrent retinal detachment, increased intraocular pressure, hyphema and inflammation are common causes of reoperation.
