METHODS: Retrospective review of 48 patients (48 hips) with follow-up duration of average 11.4 years (range, 6.1-21.4 years) was conducted. At each follow-up, Harris hip score was used to assess functional outcome, and radiographic acetabular component osteolysis was measured by DeLee and Charnley classification. Bone defects were assessed preoperatively and intraoperatively using American academy of orthopedic surgeons and Paprosky classification. The common modes of ARRH failures were evaluated. Bone consolidation, presence of heterotopic ossification, and complications such as infection and dislocation were recorded.
RESULTS: The bone defects were varied and included cavitary, segmental, and combined defects without any pelvic discontinuity. Mean Harris hip score improved from 52.6 points preoperatively to 82.0 points postoperatively. Nine acetabular revisions and 3 stem revisions (2 concurrent with acetabular revisions and 1 isolated stem revision) were performed. There were 5 infected cases and 1 patient with recurrent dislocation. The 11.4-year survival of revision THA with ARRH was 71% as the end point for acetabular revision surgery for any reason. The expected 15-year survival of revision THA with ARRH was 60%. The most common failure mode of ARRH was superomedial migration followed by lateral migration.
CONCLUSION: ARRH combined with bone grafting produces relatively good average long-term clinical results.
METHODS: Between 2006 and 2012, 22 patients underwent revision surgery using MoM bearing (28 mm femoral head in 18 hips and 32 mm in 4 hips) for ceramic bearing fracture and followed average 52.1 months. We assessed radiological parameter and functional outcome using Harris hip score (HHS) and WOMAC score. Also, serum cobalt (Co) and chromium (Cr) blood tests were performed and compared with the result obtained from age, sex- and follow-up duration-matched patients with MoM revision THA for failed polyethylene bearing.
RESULTS: The mean HHS improved from 60.6 preoperatively to 90.3 at final follow-up. There were no changes in cup position, progression of osteolytic lesions, and measurable wear of MoM bearing articulation at final follow-up radiographs. There was one case of recurrent dislocation after surgery, which was treated with greater trochanter distal advancement and one case of deep infection, which underwent two-stage revision. Mean serum Co level (1.7 vs. 1.4 μg/dl; p = 0.211) and Cr level (0.70 vs. 1.01 μg/dl; p = 0.327) showed no significant difference.
CONCLUSIONS: MoM articulation with liner cementation into the acetabular cup along with total synovectomy can be chosen in revision surgery for ceramic fracture with good midterm follow-up. However, the use of MoM bearing is indicated when the stem and metal shell can be retained and ceramic on ceramic or ceramic on polyethylene bearing cannot be selected. Also long-term outcome needs to be further evaluated.
METHODS: A retrospective analysis of 154 patients who underwent mitral valve repair using various chordal reconstructive procedures from 1992 to 2012. Patients were divided into group A and group B based on use of artificial chords and autologous in situ chords, respectively, for the repair. There were 102 (66.2%) patients in group A and 52 (33.8%) patients in group B. The mean age at repair was 11.1 ± 4.5 years. Associated cardiac anomalies were found in 94 (61%) patients.
RESULTS: The median follow-up period was 4.2 years (Interquartile range: 2.0-9.9). There were two (1.3%) early deaths and five (3.2%) late deaths. There was no significant difference in survival at 15 years between the two groups (group A: 91.8% vs group B: 95.1%; P = .66). There was no significant difference in the freedom from reoperation at 15 years between group A (79.4%) and group B (97.2%; P = .06). However, there was significant difference in freedom from valve failure between group A (56.5%) and group B (74.1%; P = .03). Carpentier functional class III and postoperative residual mitral regurgitation (2+ MR, ie, mild-moderate MR) were the risk factors for valve failure.
CONCLUSIONS: Severity of the disease and its progression has profound effect on the valve repair than the technique itself. Both chordal reconstructive procedures can be used to produce satisfactory results in children.
METHODS: The medical records of 24 patients who underwent repeat MUS surgery at a single tertiary center from January 2004 to February 2014 were reviewed. The types of MUS used for the repeat surgey were transobturator, retropubic and single incision slings. Objective cure was defined as no demonstrable involuntary leakage of urine during increased abdominal pressure in the absence of a detrusor contraction observed during filling cystometry, and subjective cure was defined as a negative response to Urogenital Distress Inventory six (UDI-6) question 3 during follow-up between 6 months and 1 year postoperatively. The change in the inclination angle between the urethra and pubic axis was measured with introital ultrasonography and the cotton swab test performed.
RESULTS: The objective and subjective cure rates were 79.2 % and 75 %, respectively. There were no differences in demographics between the patients with failure of surgery and those with successful surgery. Significant independent risk factors for failure of repeat MUS surgery were a change in cotton swab angle at rest and straining of <30° (OR 4.6, 95 % CI 2.5 - 7.9°), a change in inclination angle of <30° (OR 4.6, 95 % CI 2.5 - 7.9°), intrinsic sphincter deficiency (OR 3.4, 95 % CI 1.8 - 6.1) and a mean urethral closure pressure of <60 cm H2O (OR 2.9, 95 % CI 1.5 - 4.5). In one patient the bladder was perforated.
CONCLUSIONS: Repeat MUS surgery is safe and has a good short-term success rate, both objectively and subjectively, with independent risk factors for failure related to bladder neck hypomobility and poor urethral function.
METHODS: This prospective clinical study included consecutive Asian patients with dark irides and confirmed for glaucoma. Only one eye of each patient was treated. Diode laser contact transscleral cyclophotocoagulation treatment was performed with the center of the probe placed 1.5 mm behind the limbus. About 30 pulses of 810-mm laser radiation (power, 1.8 to 2.0 W; duration, 0.3 to 0.5 second) were applied around the eye. Patients were examined at fixed postoperative intervals. Intraocular pressure levels and postoperative complications were recorded. The relation between patient and disease characteristics, total laser energy delivered, and intraocular pressure effects were analyzed.
RESULTS: Thirty-three patients were studied, with a mean follow-up period of 9.4 months. An average 56% of patients showed a 30% or greater drop in intraocular pressure. About 38% of patients achieved sustained intraocular pressure lowering to below 22 mm Hg at 18 months. Complications were few and included transient hypotony and iritis.
CONCLUSIONS: In Asian patients with refractory glaucoma or painful glaucomatous eyes with poor visual acuity (defined for this study as worse than 20/200), low-energy-setting diode laser contact transscleral cyclophotocoagulation by means of the glass ball probe is relatively effective and safe.
METHODS: Incidence of thigh pain was lower in 2008 compared to 2006 and 2007 (p < 0.0001). The percentage of patients requiring blood transfusions (p = 0.09), duration of IDC ≥ 7 days (p = 0.27), wound dehiscence and re-operation rate were lower in 2008 in contrast to 2006 and 2007 (p = 0.43). Only 209 patients (82.3%) were available for review at 1 year. There were two (1.0%) cases of recurrent vault prolapse.
RESULTS: The subjective and objective cure rates at 1 year after this mesh implant surgery in 2006, 2007 and 2008 were 92.1% and 92.1%; 97.0% and 92.4% and 100% and 97%, respectively. The mesh erosion rate was remarkably lower in 2008 as compared to 2007 and 2006 (p < 0.001).
CONCLUSIONS: This synthetic mesh-augmented implant surgery is effective and safe, and surgical outcome appears related to the learning curve of the surgeon.
CASE REPORT: A series of three patients who developed recurrent pelvic organ prolapse more than 9 years after sacrocolpopexy. A 50-year-old and two 77-year-old patients who presented with recurrent pelvic organ prolapse at 9, 15 and 17 years, respectively after the primary abdominal sacrocolpopexy were managed by transvaginal mesh surgery.
CONCLUSION: Management of recurrent pelvic organ prolapse using transvaginal mesh would be an option for patients treated previously by sacrocolpopexy.
METHODS: From January 2013 till March 2018, a total of 55 patients with acute unilateral closed midshaft clavicle fracture were treated with either a 3.5-mm pre-contoured LCP [32 patients; 25 men and 7 women; mean age: 35 years (range: 19-63 years)] or a 3.5-mm nonlocked reconstruction plate [23 patients; 20 men and 3 women; mean age: 31.4 years (range: 17-61 years)]. The clinical outcomes in terms of fracture union, Quick Disability of Arm, Shoulder and Hand (DASH) score, implant irritation, failure rate, and reoperation rate were evaluated retrospectively. The patient billing records were reviewed to obtain primary operation, reoperation, and total operative cost for midshaft clavicle fracture. These values were analyzed and converted from Malaysia Ringgit (RM) to United States Dollar (USD) at the exchange rate of RM 1 to USD 0.24. All patients were followed up for at least one-year duration.
RESULTS: The mean time to fracture union, implant irritation, implant failure, and reoperation rate showed no significant difference between the two groups of patients. The mean Quick DASH score was significantly better in the reconstruction plate group with 13 points compared with 28 points in the LCP group (p=0.003). In terms of total operative cost, the LCP group recorded a cost of USD 391 higher than the reconstruction plate group (p<0.001).
CONCLUSION: The 3.5-mm reconstruction plate achieved not only satisfactory clinical outcomes but was also more cost-effective than the LCP in the treatment of displaced midshaft clavicle fractures.
LEVEL OF EVIDENCE: Level III, Therapeutic study.
Subject and Methods: A total of 27 patients underwent surgery between 2001 and 2015, and they were followed up for a mean period of 6.4 ± 4.1 years. Out of the 27 patients, 14 (51.9%) were infants. The median age at repair was 9.8 months. Preoperative intubation was required in six patients (22.2%), and 11 patients (40.7%) had symptoms of respiratory distress. The pulmonary valve was replaced with a valved conduit in 15 patients (55.6%), monocusp valve in 6 patients (22.2%), and a transannular patch in 6 patients (22.2%). Reduction pulmonary arterioplasty was done in all patients.
Results: The overall 10-year survival was 82.1%. There was 81.1% overall freedom from re-intervention at 10 years. No statistically significant difference was found in 10-year survival (P = 0.464) and reoperation rates (P = 0.129) between valved conduit, monocusp, or transannular patch techniques. Older children had statistically significantly longer survival (P = 0.039) and freedom from re-intervention (P = 0.016) compared to infants. Patients without respiratory complications had 100% 10-year survival and 93.3% freedom from reoperation at 10 years compared to 55.6% and 60.1%, respectively, for patients with respiratory complications.
Conclusion: There has been improvement in surgical results for APVS over the years. However, it still remains a challenge to manage infants and patients with persistent respiratory problems.
METHODS: This is a retrospective study looking at patients who underwent VSD closure with or without aortic valve intervention between January 1st, 1992 and December 31st, 2014 at the Institute Jantung Negara. This study looked at all cases of VSD and AR, where AR was classified as mild, moderate, and severe, the intervention done in each of this grade, and the durability of that intervention. The interventions were classified as no intervention (NI), aortic valve repair (AVr), and aortic valve replacement (AVR).
RESULTS: A total of 261 patients were recruited into this study. Based on the various grades of AR, 105 patients had intervention to their aortic valve during VSD closure. The rest 156 had NI. All patients were followed up for a mean time of 13.9±3.5 years. Overall freedom from reoperation at 15 years was 82.6% for AVr. Various factors were investigated to decide on intervening on the aortic valve during VSD closure. Among those that were statistically significant were the grade of AR, size of VSD, age at intervention, and number of cusp prolapse.
CONCLUSION: We can conclude from our study that all moderate and severe AR with small VSD in older patients with more than one cusp prolapse will need intervention to their aortic valve during the closure of VSD.
