Unplanned Return to the Operating Room after Tube Shunt Surgery.
Abstract
PURPOSE\nTo determine the unplanned return to OR rate within 180 days and at any time postoperatively after valved and non-valved tube shunt surgery DESIGN: : Retrospective case-control study METHODS: : Review of 357 eyes that underwent tube shunt surgery (151 valved, 206 non-valved) at an academic glaucoma service between 01/2014-12/2016. A control eye was time-matched for each eye that underwent reoperation.\n\n\nRESULTS\nThe reoperation rate within 180 days was 10.6% (16/151) for valved and 12.1% (25/206) for non-valved tube shunts and at any time postoperatively was 20.5% (31/151) for valved and 22.8% (47/206) for non-valved tube shunts. Mean postoperative follow-up was 2.8±1.1 years. The most common reoperations within 180 days and at any time postoperatively after valved tube shunt surgery were tube revision (43.8% within 180 days, 38.7% anytime) and external CPC (31.3% within 180 days, 38.7% anytime). The most common reoperations within 180 days after non-valved tube shunt surgery were tube revision (32.0%), external CPC (12.0%), and vitrectomy with AC washout (12.0%) and at any time postoperatively were tube revision (34.0%), external CPC (31.9%), and tube explant (12.8%). At last follow-up, eyes that returned to the OR and controls were similar in terms of mean IOP, proportion of eyes meeting target IOP, and change in VA.\n\n\nCONCLUSIONS\nOver 20% of eyes undergoing tube shunt surgery returned to the OR at any time postoperatively with a mean follow-up of nearly 3 years, with over 10% of eyes undergoing reoperation within the first 180 days. Rates of reoperation were similar between valved and non-valved tube shunts.
