Higher Rate Of Intraoperative Complications Research Articles

Comparison of Complications and Visual Outcomes of Combined Phacovitrectomy versus Standalone Phacoemulsification: A Multicenter Database Study.

To compare the rates of intraoperative complications, cystoid macular edema (CME), and visual outcomes in eyes that underwent combined phacovitrectomy (Phaco-PPV) to those with standalone phacoemulsification. A multicenter database study across 8 ophthalmology departments in the United Kingdom. Retrospective, nonrandomized, multicenter comparative study. We extracted data for patients who underwent Phaco-PPV and standalone phacoemulsification from January 2000 through May 2015. The primary study outcomes were the rates of intraoperative complications and CME after surgery. The study included 2222 eyes in the combined Phaco-PPV group and 112689 in the standalone phacoemulsification group. The combined Phaco-PPV group had a higher incidence of posterior capsule rupture (2.7% vs. 1.7%), dropped lens fragments (0.5% vs. 0.2%), suprachoroidal hemorrhage (0.4% vs. 0.1%), and cystoid macular edema (3.6 vs. 1.1%) (P<0.001). The mean preoperative visual acuity (VA) was lower in the combined Phaco-PPV group, with a mean VA of 0.98 vs 0.68 logMAR (Snellen ∼20/200 vs. 20/100) in the standalone phacoemulsification group (P<0.001). Visual acuity at 24 weeks was lower in the combined Phaco-PPV group (mean VA 0.67 vs. 0.22 logMAR (Snellen ∼20/100 vs. 20/32), P<0.001). Combined Phaco-PPV had higher rates of intraoperative complications and CME, along with a lower postoperative visual acuity when compared to standalone phacoemulsification surgery.

Dorsal laminectomy for the treatment of lateralised cervical intervertebral disc extrusions in dogs-Prognosis and complications.

Describe the complication rate, expected hospitalization time and prognosis associated with dorsal laminectomy for the treatment of lateralised cervical intervertebral disc extrusion (IVDE) in dogs. This is a single-center retrospective case series study. Databases were reviewed from 2012 to 2022 for dogs that had a dorsal laminectomy to treat a lateralised cervical IVDE. Dogs were excluded if additional surgical techniques were performed, or other comorbidities were found on MRI. Fifty two dogs were included the study. French bulldogs represented 28.8% of the cohort. Patient median age was 6 years and median weight 15 kg. Thirty-five dogs (67.3%) presented clinical signs for <3 days and almost half (44.2%) were ambulatory but presented cervical pain and neurological deficits. Median surgical time was 85 min. Minor intraoperative complications were reported in 22 (42.3%), with hypothermia being the most common. Thirteen (25%) needed revision surgery due to persistent cervical pain with (9/13) or without (4/13) neurological deficits. Re-extrusion or persistent extrusion was found in 92.3% of cases needing surgical revision. Median hospitalization time was 6 days. Forty-seven (90.4%) cases had a good outcome. Despite the relatively high rate of intraoperative complications and cases needing revision surgery, dorsal laminectomy as surgical treatment for lateralised cervical IVDE is still associated with good long-term prognosis in most of cases. Prognosis is good even when revision surgery is necessary but expected hospitalization time seems to be higher when compared to an alternative surgical technique.

Unilateral nephrectomy in dogs is associated with a high rate of intraoperative and postoperative complications.

To determine the incidence of complications in the intraoperative and postoperative period for dogs undergoing nephrectomy for renal disease. 69 dogs. Medical records of dogs undergoing nephrectomies for renal disease were reviewed for signalment, date of surgery, results of blood analyses, and intra- and postoperative complications. Long-term follow-up was obtained via client telephone interview or referring veterinarian medical records. A Fisher exact test was used to assess the relationship between postoperative acute kidney injury and NSAID administration with long-term development of chronic kidney disease. Complications occurred in 21.7% and 42.6% of dogs in the intraoperative and postoperative periods, respectively. Most of these were lower-grade complications, though a total of 7 dogs died during the postoperative period. An acute kidney injury was diagnosed in 12 dogs postoperatively, with 2 dogs euthanized due to the severity of the injury. Long-term follow-up was available for 53 dogs, with 24 (45.3%) dogs developing chronic kidney disease. Postoperative acute kidney injury (P = .385) and NSAID administration (P = .519) were not statistically associated with the development of chronic kidney disease in this population. Unilateral nephrectomy is associated with high intraoperative and postoperative complication rates in dogs. Chronic kidney disease was diagnosed in almost 50% of the population with available long-term follow-up.

Can the Modified Frailty Index (mFI) Predict Intraoperative and Postoperative Complications in Older Women with Endometrial Cancer Undergoing Laparoscopic or Robotic Surgery? A Multicenter Observational Study

Background: This study aims to evaluate the strength of the association between frailty and intraoperative/postoperative complications in patients undergoing minimally invasive surgery (MIS) for endometrial cancer. Methods: In this retrospective observational multicenter cohort study, frailty was defined beforehand by a modified frailty index (mFI) score of ≥3. Multiple logistic regressions were performed to investigate possible preoperative predictors—including frailty, age, and body mass index—of intraoperative and early (within 30 days from surgery) or delayed (beyond 30 days from surgery) postoperative complications. Results: The study involved 577 women, of whom 6.9% (n = 40) were frail with an mFI ≥ 3, while 93.1% (n = 537) were non-frail with an mFI of 0–2. Frail women had a significantly higher rate of intraoperative complications (7.5% vs. 1.7%, p = 0.01), with odds 4.54 times greater (95% CI: 1.18–17.60, p = 0.028). There were no differences in the rate of early postoperative complications (15% vs. 6.9%, p = 0.06) and delayed postoperative complications (2.5% vs. 3.9%, p = 0.65) for frail versus non-frail patients. The odds of early postoperative complications increased by 0.7% (95% CI: 1.00–1.15) for every one-unit increase in age (p = 0.032). Conclusions: Frailty was associated with a significantly higher risk of intraoperative complications in older women undergoing MIS for endometrial cancer. Likewise, increasing age was an independent predictor of early postoperative complications. Our findings support the practice of assessing frailty before surgery to optimize perioperative management in this patient population.

Effect of Obesity on Surgical Outcomes of Lumbar Microdiscectomy: A Retrospective Analysis of 525 Patients.

Obesity has been implicated in higher rates of intra-operative complications, as well as increased risk for recurrent herniation and re-operation following lumbar microdiscectomy (LMD). However, the current literature is still controversial about whether obesity adversely affects surgical outcomes, especially a higher re-operation rate. In this study, we have compared surgical outcomes such as recurrence of symptoms, recurrence of disc herniation, and re-operation rates in obese and non-obese patients undergoing one segment LMD. A retrospective review was conducted on patients undergoing single-level LMD between 2010-2020 at an academic institution. Exclusion criteria included prior lumbar surgery. Outcomes assessed included the presence of persistent radicular pain, imaging evidence of recurrent herniation, and the need for re-operation due to recurrent herniation. A total of 525 patients were included in the study. The mean±SD body mass index (BMI) was 31.2±6.6 (range 16.2-70.0). The mean follow-up was 273.8±445.2 days (range 14-2494). Reherniation occurred in 84 patients (16.0%), and 69 (13.1%) underwent re-operation due to persistent recurrent symptoms. Neither reherniation nor re-operation was significantly associated with BMI (p = 0.47 and 0.95, respectively). Probit analysis did not show any significant association between BMI and the need for re-operation following LMD. Obese and non-obese patients experienced similar surgical outcomes. Our results showed that BMI did not adversely affect reherniation or re-operation rate following LMD. If clinically indicated, LMD can be performed in obese patients with disc herniation without a significantly higher re-operation rate.

Resident involvement in cataract surgery at the Veterans Health Administration: complications, case complexity, and the role of experience.

To characterize intraoperative complications, case complexity, and changes in complication rates with surgical experience for cataract surgeries involving residents at the Veterans Health Administration (VHA). All VHA facilities where cataract surgery was performed. Multicenter, retrospective cohort study. A retrospective review of all cataract surgeries within the VHA between July 2010 and June 2021 was conducted. Several parameters, including resident involvement, intraoperative complications, and case complexity as determined by Current Procedural Terminology codes, and use of pupil expansion or capsular support devices, were collected. Complication rates were compared between residents and attendings. Of 392 428 cataract surgeries completed across 108 VHA facilities, 90 504 were performed by attendings alone, while 301 924 involved a resident. Of these, 10 244 (11.3%) of attending cases were complex compared with 32 446 (10.7%) of resident cases. Pupil expansion devices were required in 8191 of attending cases (9.05%) and 31 659 (10.5%) of cases involving residents ( P < .001). Similarly, cases involving residents were more likely than attending-only cases to require a capsular support device (0.835% vs 0.586%, P < .001). Cases involving residents were more likely to have posterior capsular rupture (4.75% vs 2.58%, P < .001) and dropped nucleus (0.338% vs 0.198%, P < .001). Higher resident case volumes were associated with significantly lower complication rates for posterior capsular rupture, dropped nucleus, zonular loss, and suprachoroidal hemorrhage. Although residents had higher intraoperative complication rates than attendings, these rates were reduced with surgical experience. Residents were involved in a similar number of complex surgical cases as attendings.

Comparison between the modified French AmbUlatory Cesarean Section and standard cesarean technique—a randomized double-blind controlled trial

The French AmbUlatory Cesarean Section is a cesarean delivery technique, which includes a vertical fascial incision to the left of the linea alba and an extraperitoneal approach to the uterus. The presumed benefits of this technique are decreased postoperative pain and accelerated recovery. However, evidence supporting these impressions is scarce. This study aimed to compare maternal recovery after French AmbUlatory Cesarean Section vs standard cesarean delivery technique. In this double-blind randomized controlled trial, women undergoing elective cesarean delivery at term were allocated into French AmbUlatory Cesarean Section vs standard cesarean delivery technique. A modified French AmbUlatory Cesarean Section technique was used, adhering to all French AmbUlatory Cesarean Section operative steps except for the extraperitoneal approach. In both groups, the use of intravenous hydration, intrathecal morphine, and bladder catheter was avoided, and all women were encouraged to stand and walk 3 to 4 hours after the operation. The primary adverse composite outcome included either of the following: a visual analog scale score of >6 at 3 to 4 hours after the operation, an inability to stand up and walk to the restroom 3 to 4 hours after the operation, and a 15-Item Quality of Recovery (QoR) questionnaire score of <90 at 24 hours after the operation. The women were followed up for 6 weeks. Overall, 116 women were included in the trial (58 in each group). The adverse composite outcome did not differ between the 2 groups (38.9% for the French AmbUlatory Cesarean Section group vs 53.8% for the regular cesarean delivery group; P=.172). In both groups, more than 90% of the women were able to get up and walk 3 to 4 hours after the operation. Compared with the standard cesarean delivery group, the French AmbUlatory Cesarean Section group had a longer duration of the operation (43.7±11.2 vs 54.4±11.3 minutes; P<.001), a higher rate of intraoperative complications (0.0% vs 13.8%; P=.006), and a higher rate of umbilical cord pH level of <7.2 (3.4% vs 17.2%; P=.029) were noted. Evaluation via phone call 1 week after the operation showed better quality of recovery scores in the French AmbUlatory Cesarean Section group than in the standard cesarean delivery group (27.1±8.4 vs 24.6±8.0; P=.043). Other secondary outcomes did not differ between the 2 groups. As excellent maternal recovery was noted in both groups, we believe that the main factor affecting this recovery is the perioperative management (including avoidance of the use of intraoperative intravenous hydration, intrathecal morphine, and bladder catheter, with early postoperative mobilization). The maternal and neonatal safety outcomes of the French AmbUlatory Cesarean Section technique remain to be proven by larger-scale high-quality randomized controlled trials.

Arthroscopic-assisted hip toggle stabilization in cats: An ex vivo feasibility study.

To describe arthroscopic-assisted hip toggle stabilization (AA-HTS) in cats, evaluate its feasibility and associated rate of iatrogenic injury, and assess deviations from planned surgical technique. Ex vivo study. Skeletally mature cat cadavers (n=7). Preoperative pelvic computed tomography (CT) was performed for surgical planning and to identify the ideal femoral bone tunnel projection. Ultrasound-guided transection of ligament of head of femur was performed. Following exploratory arthroscopy, AA-HTS was performed using a commercially available aiming device. Surgical time, intraoperative complications, and feasibility of technique were recorded. Iatrogenic injury and technique deviations were assessed by postoperative CT and gross dissection. Diagnostic arthroscopy and AA-HTS were successfully performed in all 14joints. Median (range) surgical time was 46.5 (29-144) min, including 7 (3-12) min for diagnostic arthroscopy and 40 (26-134) min for AA-HTS. Intraoperative complications occurred in 5 hips, related to bone tunnel creation (4) and toggle dislodgment (1). Toggle passage through the femoral tunnel was the most challenging component of technique, recorded as mildly difficult in 6 joints. No damage to periarticular/intrapelvic structures was identified. Minor articular cartilage damage (<10% total cartilage area) was identified in 10 joints. Thirteen deviations (8 major, 5 minor) in surgical technique from preoperative planning were identified in 7 joints. In feline cadavers AA-HTS was feasible but was associated with a high rate of minor cartilage injury, intraoperative complications, and technique deviations. Hip toggle stabilization using an arthroscopic-assisted approach may be an effective technique for management of coxofemoral luxation in cats.

Risk Factors for Early and Late Intraocular Lens Dislocation

Purpose: To evaluate risk factors predisposing to intraocular lens (IOL) dislocation after cataract surgery.Methods: The medical and surgical records of patients diagnosed with IOL dislocation between January 2011 and December 2021 after undergoing extracapsular cataract extraction, phacoemulsification, and phacoemulsification with pars plana vitrectomy at Hallym University Sacred Heart Hospital were reviewed retrospectively. Preoperative factors (ocular parameters and demographics) and intra-operative factors (surgery time, surgeon, and intra-operative complications) were compared according to early, late, and bilateral dislocation.Results: In 68 patents and 71 eyes, the average age at the diagnosis of dislocation was 63.3 years, and there were more males (77.5%) than females. Possible major factors predisposing to IOL dislocation were high myopia (9 eyes), retinal detachment (8 eyes), neodymium-doped yttrium aluminum garnet capsulotomy (6 eyes), and normal tension glaucoma (6 eyes). The rate of out-of-the bag dislocation was higher in early dislocation than in late. Early dislocation had a significantly older age, longer surgery time, and higher intraoperative complication rate during cataract surgery than did late dislocation. There was no difference in surgery time for late dislocated eyes compared to non-dislocated eyes. There was no difference in the incidence of dislocation between phacoemulsification and phacoemulsification with pars plana vitrectomy; there were seven eyes with prior vitrectomy only, with late dislocation. Of the seven patients with bilateral IOL dislocation, one had retinitis pigmentosa, two had retinal detachment, and one had high myopia. Bilateral dislocation patients were significantly younger at the time of cataract surgery, compared to unilateral dislocation patients.Conclusions: Early dislocation was associated with long surgery time and intraoperative complications, while late dislocation had no significant correlation with surgery-related factors. A history of vitrectomy and combined vitrectomy with cataract surgery seemed to be associated with late dislocation, but this association was not significant.

Cataract versus combined surgery in pseudoexfoliation glaucoma.

Pseudoexfoliation glaucoma (XFG) is often associated with a higher rate of intraoperative complications and failure. This study aims to compare the long-term clinical and surgical outcomes of cataract surgery alone versus combined surgery in XFG. comparative case series. All patients with XFG who underwent either cataract surgery alone [group 1: either phacoemulsification, PHACO/small-incision cataract surgery (SICS), n = 35] or combined surgery (group 2: phacotrabeculectomy, PHACOT or SICS + trabeculectomy, n = 46) from 2013 to 2018 by a single trained surgeon were screened and recalled for a detailed clinical examination, including Humphrey visual field analysis at 3-monthly intervals for a minimum of 3 years. Surgical success (intraocular pressure, IOP, <21 mm Hg and >6 mm Hg with (qualified success) or without medicines, complete success, survival rates, visual field changes, and need for additional procedures/medicines for IOP control were compared between groups. A total of 81 eyes of 68 patients with XFG were included in this study (groups 1-35 eyes and groups 2-46 eyes each). Both groups achieved 27-40% IOP reduction from preoperative IOP levels, P < 0.001. Surgical success rates were similar in both groups (complete success 66% vs 55%, P = 0.4), qualified success 17% vs 24%, P = 0.8, in groups 1 and 2). Kaplan-Meier analysis showed a marginally better survival rate for group 1, 75% (55-87%), than group 2, 66% (50-78%), at 3 and 5 years which was not significantly different. The number of eyes that progressed at 5 years after surgery (5-6%) was similar in both groups. Cataract surgery can be as effective as combined surgery in XFG eyes with regards to final visual acuity, long-term IOP profile, and visual field progression, and complications/survival rates are comparable between the two procedures.

Factors predisposing to intraoperative floppy-iris syndrome: An up-to-date meta-analysis.

Intraoperative floppy-iris syndrome (IFIS) is an increasingly recognized condition that is proven to lead to higher rates of intraoperative complications. This study provides an updated systematic review and meta-analysis regarding all the identified factors predisposing to IFIS. The study was performed in accordance with the PRISMA guidelines. 38 studies were finally included in the meta-analysis. The factors that were found to predispose to IFIS significantly were male sex (odds ratio [OR], 4.25; CI, 2.58-7.01), hypertension (OR, 1.55; CI, 1.01-2.37), tamsulosin (OR, 31.06; CI, 13.74-70.22), finasteride (OR, 4.60; CI, 1.97-10.73), benzodiazepines (OR, 2.88; CI, 1.17-7.12), and antipsychotics intake (OR, 6.91; CI, 2.22-21.50). A decreased dilated pupil preoperatively was found predisposing to IFIS (weighted mean difference -0.93; CI, -1.19 to -0.67). Intracameral epinephrine, which was investigated as a potential prophylactic measure for preventing IFIS, did not reach statistical significance (OR, 0.29; CI, 0.08-1.06). A comprehensive preoperative assessment of all risk factors is vital to stratify the surgical risk, which is crucial in addressing IFIS because unanticipated IFIS could turn a routine surgery into one of significant visual morbidity.

Comparison of clinical efficacy of single-incision and traditional laparoscopic surgery for colorectal cancer: A meta-analysis of randomized controlled trials and propensity-score matched studies.

Single-incision laparoscopy surgery (SILS) is a new laparoscopic technique that has emerged in the past decade. Whether it has advantages over conventionl laparoscopy surgery (CLS) is inconclusive. This article aimed to compare the short- and long-term outcomes of single-incision laparoscopic surgery and conventional laparoscopic surgery for colorectal cancer through high-quality literature text mining and meta-analysis. Relevant articles were searched on the PubMed, Embase, and Cochrane Library databases from January 2012 to November 2021. All data was from randomized controlled trials (RCTs) in order to increase the confidence of the analytical results.The main outcomes were intraoperative and postoperative complications. A total of 10 RCTs were included, involving 1609 patients. The quality of the included studies was generally high. No significant difference was found between SILS and CLS in the postoperative complications, operation time, postoperative hospital stay, number of lymph nodes removed, readmission, reoperation, complication level I- II, complication level IIIa, complication level IIIb, prolonged Ileus, blood loss, infection, anastomotic leakage and operation time. The results showed that SILS group had a higher rate of intraoperative complications, but it had lower incision length and better cosmetic effects. These results indicate that SILS did not have a comprehensive and obvious advantage over the CLS. On the contrary, SILS has higher intraoperative complications, which may be related to the more difficulty of SILS operation, but SILS still has better cosmetic effects, which is in line with the concept of surgical development. Therefore, the SILS needs to be selected in patients with higher cosmetic requirements and performed by more experienced surgeons.

Outcomes and Risk Factors for Complications in Cataract Patients with Hepatitis C Virus Infection

ABSTRACT Purpose To describe outcomes of patients with hepatitis C virus (HCV) seropositivity undergoing cataract surgery, as well as investigate risk factors for surgical complications. Methods This is a retrospective cohort study of all consecutive patients who underwent cataract surgery at a tertiary care hospital in the United States between 2014 and 2019. The exposure of interest was HCV seropositivity and outcomes included surgical complications and associated risk factors, visual acuity, and post-operative complications. Results A total of 11,276 eyes of 6,858 patients were included in the study, of which 122 patients (1.78%) and 210 eyes (1.86%) were HCV positive. Average age at surgery was 63.4 (8.4) years for HCV positive patients and 69.1 (10.6) years for HCV negative patients. Patients with HCV were more likely to suffer a complication during cataract surgery, 2.9% versus 1.2% (OR 2.27, 95% CI 1.03 to 5.01, p = .0415). Postoperative best corrected visual acuity was excellent: median and range 0.00 (−0.13, 3.00) logMAR for HCV positive eyes versus 0.00 (−0.30, 3.00) logMAR for HCV negative eyes. Among HCV positive patients, elevated alanine transaminase (>52 U/L) was associated with a higher intraoperative complication rate (10.0% vs 1.8%, OR 5.53, 95% CI 1.05 to 29.2, p = .044). Conclusion While patients with HCV are more likely to have complications during cataract surgery, final best corrected visual acuity was excellent regardless of HCV status. Patients with HCV are more likely to undergo cataract surgery at a younger age, and those with elevated alanine transaminase are at highest risk for complications.

Intervențiile chirurgicale repetate în eșecul fundoplicaturii la pacienții cu boala de reflux gastroesofagian

Redo surgery in failed fundoplication in patients with gastroesophageal reflux disease. Background. Laparoscopic antireflux surgery is a frequently performed procedure for the treatment of refractory gastroesophageal reflux in surgical clinics, with excellent and good symptomatic results in 90% to 95% of cases. Despite a high rate of success, the failure of laparoscopic fundoplication occurs in 2-17% of cases. When some patients can be treated conservatively, in approximately 3% to 6% cases the revision surgery is required due to recalcitrant and recurrent symptoms or appearance of complications. Methods. From 2011 to 2019, revision surgery was performed on 10 patients (all women) between the ages of 18 and 63 years. Patient demographics, primary and repeat surgery techniques, preoperative symptoms, anatomical pattern of failure, perioperative morbidity, operative complications, conversion rate, length of hospital stay, immediate and distant results were evaluated. Results. The first surgical procedure was laparoscopic Nissen-Rossetti fundoplication in 9 patients and Dor – in 1 patient. The types of fundoplication failure were: transhiatal wrap migration - 6 cases, „slipped” Nissen – 1 and paraesophageal hernia – 3. Eight patients were operated laparoscopically with the conversion rate of 50% (4 cases) – caused by dense adhesions – 3 cases, and perforation of gastric fundus – 1. Nissen fundoplication was redone in 4, converted to Toupet – in 3, newly formed after Dor fundoplication – in 1 and was left in place – in 2 patients. In all cases the repeated cruroplasty was performed, and in 3 cases - reinforcement with Gore-Tex patches. Laparoscopy operating room time was 146±54 minutes (from 95 to 240 minutes). Intraoperative complication occurred in one patient – gastric perforation. Length of hospital stay was 5 days for laparoscopic, 8 days for converted. Follow-up from 4 to 9 years: all patients without reflux symptoms, 1 – mild bloating, 2 – mild dysphagia without hernia and reflux recurrence. Conclusions. The redo surgery it is a more complex intervention, with higher technical requirements than primary one and is associated with a high rate of conversion and intraoperative complications. However, redo surgery can be carried out efficiently and safely by an experienced surgical team in dedicated centers.

Direct anterior approach hip arthroplasty: How to reduce complications - A 10-years single center experience and literature review.

BACKGROUNDThe direct anterior approach for total hip arthroplasty (DAA-THA) is increasing in popularity due to some advantages such as less surgical trauma, minimal dissection of soft tissues, shorter rehabilitation times, faster return to daily activities, lower incidence of dislocation. On the other hand, the literature reports a high rate of intraoperative complications, with many different rates and complication types in the published papers. AIMTo analyze our complications comparing results with the literature; to report measures that we have taken to reduce complications rate.METHODSAll DAA-THA patients with one year minimum follow up who were operated at a single high-volume centre, between January 2010 and December 2019 were included in this retrospective study. All surgeries were performed using cementless short anatomical or straight stems and press fit cups. Patients’ follow-up was performed, at 6 wk, 3 mo, then annually post-surgery with clinical and radiological evaluation. Primary outcomes were stem revision for aseptic loosening and all-cause stem revision. Second outcome was intra-operative and post-operative complications identification.RESULTSA total of 394 patients underwent DDA-THA from January 2010 and December 2019, for a total of 412 hips; twelve patients lost to follow-up and one patient who died from causes not related to surgery were excluded from the study. The average age at the time of surgery was 61 years (range from 28 to 78 years). Mean follow-up time was 64.8 mo (range 12-120 mo). Seven stems were revised. One cortical perforation, one trochanteric and lateral cortical wall intraoperative fracture, one diaphyseal fracture, three clinically symptomatic early subsidence and one late aseptic loosening. We also observed 3 periprosthetic fractures B1 according to the Vancouver Classification. Other minor complications not requiring stem revision were 5 un-displaced fractures of the calcar region treated with preventive cerclage, one early infection, one case of late posterior dislocation, 18 case of asymptomatic stem subsidence, 6 cases of lateral cutaneous femoral nerve dysesthesia.CONCLUSIONDAA is associated to good outcomes and lower incidence of dislocation. Complication rate can be reduced by mindful patient selection, thorough preoperative planning, sufficient learning curve and use of intraoperative imaging.

Is Cauda Equina Surgery Safe Out-of-Hours? A Single United Kingdom Institute Experience

Cauda equina syndrome (CES) can have devastating neurological sequelae if surgical treatment is delayed. However, out-of-hours surgery (weekdays from 6:00 pm to 8:00 am and all weekend operations) can potentially result in higher rates of intraoperative complications, resulting in worse outcomes. In the present study, we have described our outcomes for patients with CES during an 8-year period (December 2011 to October 2019) with the aim of assessing the risk of out-of-hours surgery. We performed a retrospective analysis of inpatient events and outcomes at 6 months of follow-up. Patient demographics, symptoms, and management data were extracted, and a risk factor analysis was performed using logistic regression. The outcome measures were the incidence of complications and symptom changes at follow-up. Symptom outcome changes between 2 time points were analyzed using repeated measures. A total of 278 patients were included in the present study. Surgery out-of-hours (P= 0.018) and prolonged operations (P= 0.018) were significant risk factors for intraoperative complications. Improved outcomes at 6 months of follow-up were found for lower back pain, sciatica, altered saddle sensation, and urinary sphincter disturbance, with no significant changes for the remaining symptoms. Out-of-hours surgeries did not significantly affect individual symptom outcomes. Our analysis has suggested that emergency decompressive surgery for patients with CES does not result in worsening of outcomes with out-of-hours surgery compared with in-hours. However, our findings also showed that no clear benefit exists to expediting surgery for those with severe presentations. Thus, decompressive surgery should be undertaken at the earliest possible time to safely do so.

Complications Related to Latarjet Shoulder Stabilization: A Systematic Review

Background: In cases of recurrent anterior shoulder instability with a glenoid defect, Latarjet procedures are widely used for stabilization. Although complications with this procedure have been reported, few studies have comprehensively analyzed issues related to the Latarjet procedure. Purpose: To identify the overall complication rate of the Latarjet procedure used for anterior shoulder instability and to compare the rate of complications between arthroscopic and open approaches. Study Design: Systematic review; Level of evidence, 4. Methods: PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed by using the PubMed, EMBASE, Scopus, and Cochrane Library databases. Data on complications were extracted and classified as intraoperative, postoperative, or instability-related for further analysis. Quality assessments were performed with criteria from the Methodological Index for Nonrandomized Studies (MINORS). A quantitative synthesis of data was conducted to compare the complication rates between arthroscopic and open approaches. Results: A total of 35 articles were included in this analysis. The MINORS score was 11.89. A total 2560 Latarjet procedures (2532 patients) were included. The overall complication rate was 16.1% (n = 412). The intraoperative complication rate was 3.4% (n = 87) and included a 1.9% (n = 48) incidence of nerve injuries and a 1.0% (n = 25) incidence of iatrogenic fractures. Screw problems, vascular injuries, and conversion arthroscopic to open surgery each occurred at a rate of <1%. The postoperative complication rate was 6.5% (n = 166), and the most common complication was nonunion (1.3%; n = 33). The instability-related complication rate was 6.2% (n = 159) and included a 1.5% (n = 38) rate of redislocation, a 2.9% (n = 75) rate of positive apprehension test, and a 1.0% (n = 26) rate of instability. Overall, 2.6% (n = 66) of patients required an unplanned secondary operation after the initial surgery. The arthroscopic approach was associated with a higher rate of intraoperative complications compared with the open approach (5.0% vs 2.9%; P =.020) and a lower rate of instability-related complications (3.1% vs 7.2%; P < .001). Conclusion: The Latarjet procedure for anterior shoulder instability results in an overall complication rate of 16.1% and a reoperation rate of 2.6%. However, serious complications at short-term follow-up appear rare. When the arthroscopic approach was used, the rate of intraoperative complications was higher, although instability-related complications were lower when compared with the open approach.

P0106 - New technique of robot-assisted laparoscopic artificial urinary sphincter implantation in female by a posterior approach with intraoperative cystoscopic monitoring

To report the early experience of a modified technique of robot-assisted artificial urinary sphincter (AUS) implantation in female, with a posterior approach to the bladder neck and intraoperative real-time cystoscopic monitoring. Retrospective monocentric study included all consecutive female who underwent a primary robot-assisted AUS implantation between 2017 and 2019. Real-time intraoperative cystoscopic monitoring was carried out to check the correct level of the dissection and to avoid any injury during bladder neck dissection. Perioperative and intraoperative data, functional outcomes and complications were assessed. Continence was defined as 0 to 1 pad per day. Twenty-four patients were included, the median age was 66 years, 23/24 (96%) had previous SUI or prolapse surgery. Two conversions to open surgery and 2 modifications of the surgical technique with anterior dissection of the bladder neck were required due to major vesicovaginal adhesions. Overall, 20 patients underwent the robotic posterior approach. Eleven intraoperative complications in 10 patients (50%) occurred, including 7 bladder injuries 4 vaginal injuries, without the need to stop the procedure. The median hospital stay was 3 days (2–7). One AUS was removed at 1 year due to vaginal erosion. At last follow-up (median 26 months (22–36)), 95% of the devices were in place and activated and the continence rate was 84%. Early functional results of robot-assisted AUS implantation with a posterior approach to the bladder neck and intraoperative cystoscopic monitoring are promising despite the high rate of intraoperative complications due to previous surgeries. Further evaluation of this technique is required.
