Abstract Introduction Microinvasive glaucoma surgery (MIGS) is a growing trend, and XEN gel implant is one of the most effective types of MIGS. This study aimed to examine factors associated with the surgical success of XEN gel implants. Methods This retrospective cohort study enrolled patients with glaucoma receiving XEN implantation alone or combined with phacoemulsification (PHACOXEN) with a follow-up period of more than 6 months at Hualien Tzu Chi Hospital, Taiwan. If intraocular pressure (IOP) elevated above 20 mmHg during the follow-up, needling or open revision was performed. The primary outcome measures included IOP and the number of glaucoma medications. Results Male patients had lower postoperative IOP; male patients and higher preoperative IOP were associated with higher IOP change rates, and older patients had a higher chance of achieving IOP

Introduction: Microinvasive glaucoma surgery (MIGS) is a growing trend, and XEN gel implant is one of the most effective types of MIGS. This study aimed to examine factors associated with the surgical success of XEN gel implants. Methods: This retrospective cohort study enrolled patients with glaucoma receiving XEN implantation alone or combined with phacoemulsification (PHACOXEN) with a follow-up period of more than 6 months at Hualien Tzu Chi Hospital, Taiwan. If intraocular pressure (IOP) elevated above 20 mmHg during the follow-up, needling or open revision was performed. The primary outcome measures included IOP and the number of glaucoma medications. Results: Male patients had lower postoperative IOP; male patients and higher preoperative IOP were associated with higher IOP change rates, and older patients had a higher chance of achieving IOP < 18 mmHg and being medication-free at months 12, 24, and 36. The Kaplan–Meier curve showed that the probability of free-of-rescue intervention over the follow-up period was not different between the XEN alone and the PHACOXEN group (P = 0.859). Both needling and open revision were effective rescue interventions, but open revision had a higher chance of achieving IOP ≤ 18 mmHg and being medication-free (P = 0.031) and required less medication afterward (P = 0.044). Older age (P = 0.013) and male patients (P = 0.022) had a lower IOP after rescue interventions. Compared with open revision, needling was associated with higher IOP (P = 0.048) and more required medications (P = 0.048). Conclusions: XEN alone and PHACOXEN had comparable surgical outcomes, whereas open revision had a better IOP lowering effect than needling as a rescue intervention. Male and older patients had better surgical results in primary XEN implantations and rescue interventions. [ABSTRACT FROM AUTHOR]

Background: Only a few studies have provided homogeneous analysis of open revision surgery after a failed arthroscopic Bankart procedure. Hypothesis: Open Bankart revision surgery will be effective in a failed arthroscopic anterior stabilization but inevitably results in a loss of range of motion, especially external rotation. Study Design: Case series; Level of evidence, 4. Methods: Twenty-six shoulders that went through traditional open Bankart repair as revision surgery after a failed arthroscopic Bankart procedure for traumatic anterior shoulder instability were enrolled for this study. The mean patient age at the time of revision surgery was 24 years (range, 16-38 years), and the mean duration of follow-up was 42 months (range, 25-97 months). Results: The preoperative mean range of motion was 173° in forward flexion and 65° in external rotation at the side. After revision surgery, the ranges measured 164° and 55°, respectively (P = .024 and .012, respectively). At the last follow-up, the mean Rowe score was 81 points, with 88.5% of the patients reporting good or excellent results. After revision surgery, redislocation developed in 3 shoulders (11.5%), all of which had an engaging Hill-Sachs lesion and associated hyperlaxity (2+ or greater laxity on the sulcus sign). Conclusion: Open revision Bankart surgery for a failed arthroscopic Bankart repair can provide a satisfactory outcome, including a low recurrence rate and reliable functional return. In open revision Bankart surgery after failed stabilization for traumatic anterior shoulder instability, the surgeon should keep in mind the possibility of a postoperative loss of range of motion and a thorough examination for not only a Bankart lesion but also other associated lesions, including a bone defect or hyperlaxity, to lower the risk of redislocation.
