Long-Term Surgical Outcomes of Ileovesicostomy at a Single Children’s Hospital

IntroductionThe ileovesicostomy (IV) is a surgical option for patients with refractory bladder dysfunction at-risk of upper tract deterioration who cannot catheterize or lack social support for managing an augmentation cystoplasty (AC). Long-term outcomes after IV in children are lacking in the literature. ObjectiveWe assessed the risk of long-term surgical complications in pediatric patients with IV at a single children’s hospital. Study designWe retrospectively reviewed the records of patients undergoing IV between 2002 to 2021 at a single children’s hospital. The primary outcome was the rate of surgical complications in IV patients after initial reconstruction. Specific complications of interest included intra-abdominal, reservoir, and stomal complications, respectively. We also assessed renal outcomes, including the change in glomerular filtration rate (ΔGFR) and Society of Fetal Urology (ΔSFU) hydronephrosis from the time of surgery to last follow up. ResultsThe study comprised 17 IV patients, with most patients having a diagnosis of spina bifida (65%). Median follow-up was 6.4 years. The mean rate of surgical complications per patient year was 0.11 +/- 0.20. On survival analysis, the time to first complication for IV was 84.4 months. The incidence of intra-abdominal, reservoir, and stomal complications over the study period was 2/17 (11.8%) for each of these complication types. The mean ΔSFU grade from the time of surgery to last follow up was -1.24 +/- 1.48 and mean ΔGFR was -2.5 +/- 32.7 ml/min. DiscussionWe found that IV in pediatric patients experience a low rate (0.11/year) of complications and that median time to first complication was 84 months. Additionally, IV offers adequate renal preservation. Our study is limited, though, by its retrospective nature, small sample size, heterogenous population and lack of comparison group. ConclusionOur experience demonstrates that IV has a low rate of surgical complications and preserves renal function. We believe it is a reasonable surgical option for the well selected patient with refractory bladder dysfunction at-risk of upper tract deterioration who is unable to reliably catheterize.

Long-term surgical outcomes of combined Ahmed glaucoma valve implantation and phacoemulsification with intraocular lens implantation for patients with glaucoma secondary to iridocorneal endothelial syndrome

BackgroundTo assess the long-term outcomes of patients with glaucoma secondary to iridocorneal endothelial syndrome (GS-ICE) who underwent Ahmed glaucoma valve (AGV) implantation combined with phacoemulsification and intraocular lens (IOL) implantation surgery.MethodsIn this non-comparative retrospective case series study, twelve patients with uncontrolled GS-ICE and cataract underwent Ahmed aqueous shunt combined with phacoemulsification and IOL implantation surgery at Beijing Tongren Eye Center between June 2014 and June 2022. Main medical records included best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of antiglaucoma medications (AGM), corneal status and further surgical interventions. Surgical success was defined as a postoperative IOP ≥ 6mmHg and ≤ 21mmHg without (complete success) or with/without (qualified success) topical AGM and vision of at least light perception during the follow-up period.ResultsTwelve eyes of twelve patients were reviewed. Preoperative IOP was decreased from a mean of 38.5 ± 6.7 mmHg on 3.3 ± 0.9 AGM to a mean of 16.3 ± 4.3 mmHg (P<0.001) on 0.6 ± 1.1 medications (P<0.001) at the last follow-up (47.0 ± 24.7 months). Eight eyes (66.7%) had stable vision or at least one line improvement than that before surgery. Eight eyes (66.7%) achieved qualified success and six eyes (50.0%) achieved complete success after surgery. The surgical procedure had a qualified survival of 91.7% at 1 year, 82.5% at 3 years, 72.2% at 5 years, and 48.1% at 7 years.ConclusionAGV implantation combined with phacoemulsification and IOL implantation seems to be an effective method in IOP control and vision maintain for patients with GS-ICE. The combined surgical procedure may be a reliable option for those GS-ICE patients with coexisting cataract.

Acquired Ankyloblepharon Correction Using Ocular Surface and Tarsal Mucous Membrane Grafting in Cicatrizing Ocular Surface Diseases

Purpose: To report the long-term surgical outcomes of acquired ankyloblepharon correction using mucous membrane graft. Methods: Five eyes of 4 patients (median age, 19 years) with acquired ankyloblepharon were managed using eyelid splitting and mucous membrane graft anchored to the recti muscles on the bulbar surface in the respective quadrant and onto the bare tarsal surface. Outcome measures include a change in the palpebral fissure width, ability to fit scleral contact lenses, visual acuity, and cosmesis. Results: The underlying etiologies of ankyloblepharon were chronic Stevens-Johnson syndrome (n = 3), and chemical injury (n = 2). All 5 eyes had conjunctival shortening, and 3 had severe dry eyes (median Schirmer 4.5 mm). Four eyes had limbal stem cell deficiency. The median horizontal palpebral fissure width improved to 22 mm from 8 mm. This single-staged surgical technique allowed for fornix formation and prosthetic replacement of the ocular surface ecosystem lens fitting in all 5 eyes. Median logMAR visual acuity improved from 2.1 to 0.7 following ankyloblepharon release, prosthetic replacement of the ocular surface ecosystem lens fitting in 4 eyes, and keratoprosthesis in 1 eye. Repeat mucous membrane graft for recurrent symblepharon in 1 quadrant was required in 2 eyes where complete 360 degrees bulbar and tarsal conjunctiva loss were present preoperatively. At the median follow-up period of 27 months, all patients reported better cosmesis and had no symblepharon recurrence following repeat surgery in 2 eyes and single surgery in 3 eyes. The donor site healed well without any complications. No mitomycin C or symblepharon ring was used. Conclusion: Ocular surface and adnexal reconstruction using bulbar and tarsal mucous membrane grafts help visually rehabilitate patients with acquired ankyloblepharon secondary to cicatrizing ocular surface disorders.

Pre-operative clinical deterioration and long-term surgical outcomes in 41 patients with split cord malformation type 1.

To document the pre-operative rate of clinical deterioration in a cohort of patients with split cord malformation type 1 (SCM 1) and the early- and long-term surgical outcome in these patients. Data from 41 patients with SCM 1 operated upon by the same surgeon (VR) between January 2008 to June 2023 were retrospectively reviewed with respect to history of clinical deterioration prior to surgery and early and long-term surgical outcomes. The mean age of the patients at presentation was 79.3months and the male to female ratio was 1:1.93. Twelve (29%) patients had congenital deficits whereas 4 (10%) patients had no neurological deficits. Twenty-six (63%) patients had kyphoscoliosis and 25 (61%) patients had motor dysfunction. Thirty-three (81%) patients (8/12 (67%) with congenital deficits) had clinical deterioration prior to surgery. By the age of 2years, 56% of patients had clinical deterioration. After surgery, 18 (55%) patients with progressive symptoms had improvement in one or more of their symptoms on long-term follow-up (mean, 63.4months). There were no predictors of surgical outcome. Since over half of our patients with SCM 1 developed progression of congenital deficits or developed deficits by the age of 2years, surgery should be performed as soon as possible in these children. On long-term follow-up after surgery, improvement can be expected in over half the patients.

Long-Term Surgical Outcomes of Primary Rhinoplasty.

To examine the impact of primary rhinoplasty on subsequent rhinoplasties for patients with cleft lip nasal deformity. Retrospective cohort study. Tertiary care pediatric hospital. Individuals who underwent definitive cleft lip repair at our institution from 2000 to 2006 with a current age of 18 or older. Number and timing of subsequent rhinoplasties. Among 199 individuals, 94 (47.2%) underwent primary rhinoplasty. Follow-up was 15.0 ± 4.8 years in the PR cohort and 15.0 ± 5.1 years in the NPR cohort (p = 0.993). In bilateral cleft lip, interdomal suture predicted fewer subsequent rhinoplasties (β=-0.310, p = 0.033), while history of primary rhinoplasty predicted greater age at subsequent rhinoplasty (β=1.800, p = 0.040). Among individuals with follow-up beyond age 18, intranasal stenting predicted fewer subsequent rhinoplasties (β=-0.609, p = 0.015). Most underwent subsequent nasal correction aside from 7 (19.4%) and 9 (20.9%) in the PR and NPR cohorts, respectively (p = 0.536). There was no difference in mean subsequent rhinoplasties between cohorts (1.1 ± 0.8 versus 1.3 ± 1.1, p = 0.284). Individuals with complete cleft lip underwent more lifetime rhinoplasties (1.9 ± 1.0 versus 1.2 ± 1.2, p = 0.007). Primary rhinoplasty with interdomal tip sutures in bilateral cleft lip was associated with fewer subsequent rhinoplasties. Primary rhinoplasty may delay subsequent nasal correction, though most who underwent primary rhinoplasty ultimately required nasal correction later in childhood. Postoperative nasal stenting may provide longer-term nasal benefits and should be considered at time of definitive cleft lip repair.

Iatrogenic pediatric unilateral vocal cord paralysis after cardiac surgery: a review.

Unilateral vocal cord paralysis (UVCP) is a growing area of research in pediatrics as it spans across many specialties including otolaryngology, cardiology, general surgery, respirology, and speech language pathology. Iatrogenic injury is the most common cause of UVCP, however there is a wide range of data reporting the prevalence, symptom burden, and best treatment practice for this condition. The literature included systematic reviews and meta-analyses, retrospective studies and limited prospective studies. Overall, the literature lacked consistency in the diagnosis, treatment, and long-term outcomes of patients with UVCP. Many articles conflated bilateral vocal cord paralysis (BVCP) with UVCP and had limited data on the natural history of the condition. There was no consensus on objective and subjective measurements to evaluate the condition or best indications for requiring surgical intervention. Thyroplasty, injection medialization (IM) and recurrent laryngeal nerve reinnervation (RLNR) were the reported surgical interventions used to treat UVCP, however there was limited data on short and long-term surgical outcomes in children. More research is needed to determine the true prevalence, natural history, indications for surgical intervention and long-term outcomes for pediatric patients with this condition.

Cumulative re-operation rates during follow-up after hypospadias repair.

To assess the cumulative rates of re-operations after hypospadias repair and evaluate long-term surgical outcomes at a tertiary paediatric urology centre. Retrospective analysis of 293 boys born between 1991 and 2003 undergoing hypospadias surgery was conducted. The study included 274 patients: 165 with distal, 34 with midshaft, and 75 with proximal hypospadias. Kaplan-Meier methods were used to evaluate the re-operation data. The median age at primary surgery was 1.3 years, with a median follow-up of 14.4 years. The overall re-operation rate was 48.2%, with approximately half of the problems detected within the first 3 months after surgery. The risk of re-operation was correlated with hypospadias severity, with 5- and 15-year re-operation risks at 39.3% and 51.8%, respectively. Limitations of the study include its retrospective nature and variations in surgical techniques from current standards. There is a significant risk of unplanned re-operations following hypospadias repair, increasing with the severity of the original condition. This underscores the need for extended follow-up and effective communication with patients and their families about the likelihood of requiring multiple surgeries for optimal outcomes.

Long-Term Outcome of Surgery for Grade 4 Gynecomastia: A Single-Center Experience

Abstract Background Gynecomastia results in a feminine appearance of the male chest, leading to social embarrassment and loss of self-esteem in the afflicted males. Grade 4 gynecomastia is expected to have less than perfect results with liposuction and gland excision alone. This study was done to assess the long-term outcome of this surgery for grade 4 gynecomastia. Materials and Methods From January 2021 to December 2022, 81 patients with grade 4 gynecomastia were treated by us. All the patients underwent vibration amplification of sound energy at resonance (VASER) and suction-assisted liposuction of the chest and side rolls with excision of the gland with crescentic lift in the cases with ptosis. A retrospective study was done to analyze the long-term surgical outcomes in these patients by review of clinical records. Results Symmetry was achieved in 37/39 patients with grade 4a gynecomastia but only in 33/42 patients with grade 4b gynecomastia. The inframammary fold disappeared in 35/39 patients with grade 4a gynecomastia but only in 25/42 of grade 4b gynecomastia patients. Ptosis was corrected in 35/42 grade 4b gynecomastia patients. The mean follow-up was 15 months (range: 12–24 months). Only seven patients desired a second stage to correct the remaining deformity. Conclusion Liposuction with gland removal alone in grade 4a gynecomastia and with liposuction with crescentic nipple–areola complex (NAC) lift in patients of grade 4b gynecomastia give satisfactory results in patients with massively enlarged breasts. While grade 4a gynecomastia has overall better results and lesser complications as compared with grade 4b gynecomastia, the latter also has acceptable outcomes. Realistic prognosis needs to be explained to the patient preoperatively.

778. ROBOTIC-ASSISTED EPIPHRENIC DIVERTICULECTOMY: 9 YEAR EXPERIENCE OF A TERTIARY CENTER

Abstract Background Epiphrenic esophageal diverticula are rare and often associated with esophageal motor disorders. Surgery is reserved for larger diverticula with symptoms that significantly impair quality of life. When possible, a transhiatal approach can reduce pulmonary complications by preserving pleural integrity; more proximal diverticular openings require a combined transthoracic and abdominal approach to achieve complete excision. Robotic surgery assists in precise dissection and preservation of delicate mediastinal structures. Currently, few reports are available on larger patient cohorts of robotic diverticulectomy. We describe all consecutive cases of robotic-assisted epiphrenic diverticulectomy performed at a high-volume tertiary center, since robotic surgery became available in 2015. Methods A retrospective chart review was conducted and, for all consecutive diverticulectomy cases, surgical techniques, patient characteristics and short and long-term outcomes were recorded. All patients underwent preoperative EGDS and esophagogram. Diverticulectomy was always accompanied by esophagogastric Heller myotomy (&amp;gt;7 cm) and Dor fundoplication with the Xi DaVinci system was performed. One to two SIGNA linear stapler firings were used for diverticular resection. Symptoms, demographic data, and short and long-term surgical outcomes were recorded, including morbidity and mortality and post-operative symptoms. Results Four cases required both an abdominal and intrathoracic approach, none was converted. Intraoperative complications included one occurrence of splenic bleeding controlled by hemostatic. Intraoperative blood loss was negligible. In two cases an esophageal leiomyoma was found incidentally and excised. The only postoperative complication was trocar-related abdominal wall bleeding that led to reintervention for cauterization; mortality was zero. All patients underwent a post-op esophagogram, negative for leaks or strictures, and resumed soft feeding within 7 days. All reported substantial symptom relief at six months. At one year, one patient reported reflux, and two reported dysphagia recurrence without evident structures or recurrences. Conclusion Robotic-assisted diverticulectomy is safe and effective for epiphrenic diverticula. The abdominal approach allows for a thorough esophageal myotomy associated with a For antireflux procedure to reduce recurrences of the disease and long-term dysphagia. In some cases a transthoracic approach is also needed, when employed by experienced upper GI surgeons it doesn't significantly affect surgical outcomes. Quality of life improves after surgery, although symptomatic reflux might occur. Further prospective or experimental studies are needed to evaluate short and long-term outcomes of the robotic approach compared to other surgical approaches.

Long-term Functional, Sexual, and Cosmetic Outcomes in Adult Patients Who Underwent Hypospadias Repair During Childhood at a Highly Specialized Italian Pediatric Hospital.

This study aims to evaluate long-term functional, sexual, and cosmetic outcomes in adult patients who underwent hypospadias repair during childhood at a national highly specialized pediatric hospital. Medical records of pediatric patients who had undergone surgical repair of hypospadias between 1993 and 2004 at Meyer Children Hospital of Florence were reviewed. Adult patients were contacted by telephone between July and August 2021 and invited to participate. Long-term surgical outcomes were assessed focusing on complications and reinterventions, and 3 validated questionnaires on urinary function, erectile function, and penile cosmetic appearance were administered. From January 1993 to December 2004, a total of 799 patients with hypospadias underwent repair surgery. Two hundred thirty-nine patients gave consent to be included in the study. Follow-ups occurred between 17 and 28 years after the first surgery. Most patients had anterior localization of hypospadias (210/239) and associated penile curvature (132/239). The most frequent surgery for hypospadias repair was meatal advancement and glanduloplasty incorporated (MAGPI) (88/239), and the most used surgical treatment for penile curvature was the Nesbit technique (49/132). The complication rate was 27% (65/239) in an average time of 4.7 years, and 48 surgical procedures have been performed to treat them. At follow-up, the mean IPSS was 0.96± 1.97, the mean IIEF-5 score was 24.10 ± 1.02, and the mean HOSE score was 15.47 ± 0.45. Patients who underwent reintervention reported a lower IPSS than those who underwent only 1 surgery (0.29 vs. 1.16). Hypospadias repair during childhood leads to rather normal urinary and sexual function and penile cosmetic appearance in adolescence and adulthood.

Unraveling the mysteries of parsonage turner syndrome: A journey towards optimal management. A systematic review

AimsParsonage Turner Syndrome (PTS) is a peripheral neuropathy manifesting as sudden onset pain, muscle weakness, and atrophy. This review aims to analyse long-term outcomes reported in adult patients with PTS, and establish an optimised management approach. MethodsA comprehensive literature search was performed using MEDLINE, PubMed, and the Cochrane Library. Articles that met the eligibility criteria were included. Analysis on time to presentation, presentation, interventions and long-term functional outcomes was conducted. All relevant information was collected by two independent reviewers. ResultsTwenty-five studies, comprising 950 PTS patients, were identified. Patients averaged 43.8 years in age, with a F:M ratio of 0.6:1, and presented symptoms spanning 1–24 months prior to seeking medical attention. Management details were elucidated for 402 patients (42 ​%), with 87 ​% managed conservatively. Among conservatively managed patients, over 50 ​% exhibited no improvement. 62/402 (15 ​%) necessitated surgical interventions, including neurolysis, decompression, nerve transfers, and diaphragmatic plication. 25/31 (80.6 ​%) neurolysis cases demonstrated full functional recovery, including pain resolution and full muscle strength, between 1 day and 13 months (average 2.9 months). 2 nerve transfer cases achieved full forward flexion at 2.5 months. Overall, long-term outcomes of PTS, reported at 5–25 months, revealed residual neuropathic pain in 60 ​% and incomplete motor function return in 70 ​% of patients. ConclusionsPTS recognition and referral challenges persist, impeding timely management. While surgical interventions are advocated after three months for incomplete recovery, long-term surgical outcomes are inadequately reported. An optimal surgical strategy for stagnant nerve recovery needs to be devised for this challenging cohort of patients.

Effect of Preoperative Anterolateral Ligament Injury on Outcomes After Isolated Acute ACL Reconstruction With Hamstring Graft: A Prospective Study With Minimum 5-Year Follow-up

Background: The potential influence of a preoperative anterolateral ligament (ALL) lesion seen on magnetic resonance imaging (MRI) on the mid- and long-term surgical outcomes of anterior cruciate ligament (ACL) reconstruction is still controversial. Purpose: To evaluate the clinical outcomes and failure rate of isolated ACL reconstruction at a minimum 5-year follow-up in patients with and without ALL injury diagnosed preoperatively using MRI. Study Design: Cohort study; Level of evidence, 2. Methods: A prospective cohort of patients with acute ACL injury was divided into 2 groups based on the presence (ALL injury group) or absence (control group) of ALL injury on preoperative MRI. This is a longer-term follow-up study of a previously published study that had a minimum 2-year follow-up. Both groups underwent anatomic isolated reconstruction of the ACL. The Lysholm and subjective International Knee Documentation Committee scores, KT-1000 arthrometer and pivot-shift tests, reconstruction failure rate, incidence of contralateral ACL injury, presence of associated meniscal injury, and presence of knee hyperextension were evaluated. The evaluation at the 5-year follow-up was also compared with the same patient’s evaluation at 2 years of follow-up. Results: A total of 156 patients were evaluated. No significant differences were found between the groups in the preoperative evaluation. In the postoperative evaluation, patients in the ALL injury group had a higher reconstruction failure rate (14.3% vs 4.6% for the control group; P = .049) and worse clinical outcomes according to the Lysholm scores (85.0 ± 10.3 vs 92.3 ± 6.6; P < .00001). Although the pivot-shift test results were similar, anteroposterior translation using the KT-1000 arthrometer revealed worse results for the ALL injury group (2.8 ± 1.4 mm vs 1.9 ± 1.3 mm; P = .00018). Patients in the ALL injury group also had an increase in KT-1000 arthrometer values from 2 to 5 years (2.4 ± 1.6 vs 2.8 ± 1.4; P = .038). Patients in the control group had no differences in outcomes from 2 to 5 years of follow-up. Conclusion: Combined ACL and ALL injuries were associated with significantly less favorable outcomes than were isolated ACL injuries at a minimum follow-up of 5 years after isolated ACL reconstruction with hamstring autograft. Patients with concomitant ALL injury showed a higher failure rate and worse functional scores. Also, knee stability tended to slightly worsen from 2 to 5 years in cases of associated ALL injury.

Laparoscopic Vecchietti procedure: pearls for success

To present an effective strategy for optimizing the care of patients with Müllerian agenesis who desire surgical management for the creation of a neovagina with the laparoscopic Vecchietti procedure. This video provides a framework for patient evaluation and selection, surgical strategy, and postoperative care regimen to provide optimal postprocedural outcomes. Academic Hospital. This is a 22-year-old patient with Müllerian agenesis who was unsuccessful with conservative strategies for vaginal lengthening and sought care for neovagina creation. The patient underwent preoperative pelvic floor physical therapy and vaginal dilation, both of which were ineffective in producing adequate vaginal lengthening. We then performed a laparoscopic Vecchietti procedure. The procedure occurred at a large academic institution with two obstetrics-gynecology subspecialty surgeons providing perioperative care. A vaginal length of 7 cm was achieved, which was sustained at >12 months. The patient was managed by a multidisciplinary team using our established care regimen, with follow-up demonstrating a sustained positive treatment outcome. The vaginal length at more than 1 year after the procedure measured 7 cm. Using a methodological, patient-focused approach and an experienced multidisciplinary team can optimize immediate- and long-term surgical outcomes for patients with Müllerian anomalies who do not have acceptable success with conservative methods.

Patients report significant improvement in quality of life following hiatal hernia repair-despite recurrence.

Hiatal hernia (HH) repairs have been associated with high recurrence rates. This study aimed to investigate if changes in patient's self-reported GERD health-related quality of life (HRQL) scores over time are associated with long-term surgical outcomes. Retrospective chart reviews were conducted on all patients who had laparoscopic or robotic HH repairs between 2018 and 2022 at a tertiary care center. Information was collected regarding initial BMI, endoscopic HH measurement, surgery, and pre- and post-operative HRQL scores. Repeat imaging at least a year following surgical repair was then evaluated for any evidence of recurrence. Paired t tests were used to compare pre- and post-operative HRQL scores. Wilcoxon ranked-sum tests were used to compare the HRQL scores between the recurrence cohort and non-recurrence cohorts at different time points. A total of 126 patients underwent HH repairs and had pre- and post-operative HRQL scores. Mesh was used in 23 repairs (18.25%). 42 patients had recorded HH recurrences (33.3%), 35 had no evidence of recurrence (27.7%), and 49 patients (38.9%) had no follow-up imaging. The average pre-operative QOL score was 24.99 (SD ± 14.95) and significantly improved to 5.63 (SD ± 8.51) at 2-week post-op (p < 0.0001). That improvement was sustained at 1-year post-op (mean 7.86, SD ± 8.26, p < 0.0001). The average time between the initial operation and recurrence was 2.1years (SD ± 1.10). Recurrence was significantly less likely with mesh repairs (p = 0.005). There was no significant difference in QOL scores at 2weeks, 3months, 6months, or 1 year postoperatively between the cohorts (p = NS). Patients had significant long-term improvement in their HRQL scores after surgical HH repair despite recurrences. The need to re-intervene in patients with HH recurrence should be based on their QOL scores and not necessarily based on established recurrence.

Long-Term Surgical Outcomes of Scleral Flap versus Scleral Pocket Technique for Sutureless Intrascleral One-Piece Lens Fixation.

Objectives: This study compared long-term surgical outcomes of the scleral flap versus scleral pocket technique for sutureless intrascleral one-piece intraocular lens (IOL) fixation. Methods: A retrospective comparative study was conducted at a single center, involving consecutive patients undergoing sutureless intrascleral one-piece IOL implantation, between January 2020 and May 2022. Eyes were divided into two groups based on the surgical technique: group 1 underwent scleral flap (n = 64), and group 2 received scleral pocket technique (n = 59). Visual acuity, refractive outcomes, and complications were assessed over a minimum 24-month follow-up period. Results: Both groups showed improvements in best-corrected visual acuity (BCVA), increasing from 0.84 ± 0.56 logMAR at baseline to 0.39 ± 0.23 logMAR (p = 0.042) at 24 months in group 1 and from 0.91 ± 0.63 logMAR at baseline to 0.45 ± 0.38 logMAR (p = 0.039) at 24 months in group 2. No significant differences in BCVA were observed between the groups at baseline (p = 0.991), 12 (p = 0.496) and 24 months (p = 0.557). Mean spherical equivalent (-0.73 ± 1.32 D in group 1 and -0.92 ± 0.99 D in group 2, p = 0.447), refractive prediction error (-0.21 ± 1.1 D in group 1 and -0.35 ± 1.8 D in group 2, p = 0.377), and surgically induced astigmatism (0.74 ± 0.89 D in group 1 and 0.85 ± 0.76 in group 2, p = 0.651) were comparable between the two groups. An IOL tilt of 5.5 ± 1.8 and 5.8 ± 2.0 degrees (p = 0.867) and an IOL decentration of 0.41 ± 0.21 mm and 0.29 ± 0.11 mm (p = 0.955) were obtained, respectively, in group 1 and group 2 at 24 months. Mean endothelial cell density remained stable at 24 months in both groups (p = 0.832 in group 1 and p = 0.443 in group 2), and it was 1747.20 ± 588.03 cells/mm2 in group 1 and 1883.71 ± 621.29 cells/mm2 in group 2 (p = 0.327) at baseline, 1545.36 ± 442.3 cells/mm2 in group 1 and 1417.44 ± 623.40 cells/mm2 in group 2 (p = 0.483) at 24 months. No cases of endophthalmitis were observed. Conclusions: The scleral pocket technique for sutureless intrascleral one-piece IOL fixation is comparable to the traditional scleral flap technique in terms of long-term visual outcomes and safety. The scleral pocket technique offers a simplified approach and a viable option even for less experienced surgeons.

Symmetric versus asymmetric surgery for the treatment of intermittent exotropia with equal dominance.

Long-term surgical outcomes were compared between bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession combined with medial rectus resection in the same eye (R&R) for therapy of basic type intermittent exotropia (IXT) with equal dominance. Two hundred and sixty-eight subjects (3-11 years old) with basic IXT with equal dominance who underwent BLR or R&R surgery were enrolled to this study, and with a minimum follow-up period of 18 months. One hundred and fourteen patients underwent BLR surgery and 144 underwent R&R surgery at a single centre. Surgical outcomes between groups were compared. Surgery results were divided into 3 categories: undercorrection/recurrence (exotropia/phoriaå 10PD), success(esotropia/phoria ≤5PD to exotropia/phoria≤10PD), and overcorrection (esotropia/phoriaå 5 PD) according to postoperative deviation angle. No statistical difference was detected between BLR group and R&R group at all intervals with the exception of the last examination, demonstrating a higher success rate and a lower recurrence rate in the BLR group than R&R group at last visit (P = 0.04). Additionally, the BLR group demonstrated a smaller exodrift than the R&R group at distance and near fixation (P = 0.01; P = 0.03). Stereoacuity and exotropia control showed overall improvement following both surgeries, and this improvement had no statistical difference between groups(P > 0.05). BLR showed better long-term results than R&R in the treatment of basic type intermittent exotropia with equal dominance given its low recurrence rate. Both BLR and R&R surgeries could improve stereoacuity function and exotropia control, and to same extents.
