RESUMEN
OBJECTIVE: To evaluate the efficacy of scheduled second-look endoscopy in patients with acute peptic ulcer bleeding (PUB). MATERIALS AND METHODS: We systematically search in four databases for randomized controlled trials (RCTs) that evaluated the usefulness of scheduled second-look endoscopy vs. single endoscopy in patients with PUB. Our primary outcome was rebleeding. Secondary outcomes were surgery, mortality, and the number of units of blood transfused (NUBT). All meta-analyses were performed using a random-effects model. Pooled risk ratio (RR) and mean difference (MD), with their 95% confidence intervals (CIs) were calculated for categorical and continuous outcomes, respectively. The risk of bias was assessed using the Cochrane RoB 2.0 tool, and the quality of evidence (QoE) was rated with the GRADE approach. RESULTS: Eight full-text RCTs and two RCT abstracts were included (n=1513). We did not find differences in rebleeding (RR, 0.78; 95% CI, 0.53-1.14, moderate QoE), surgery (RR, 0.58; 95% CI, 0.29-1.15, moderate QoE), mortality (RR, 0.89; 95% CI, 0.46-1.71, moderate QoE) or NUBT (MD, -0.01 units; 95% CI, -0.3 to 0.28, low QoE) between second-look and single endoscopy. Sensitivity analyses had similar results to the main analyses. CONCLUSIONS: Routine second-look endoscopy was not more efficacious than single endoscopy in patients with PUB.

IMPORTANCE: The formation of adhesions after gynecological surgery not only has detrimental impacts on those affected, including pain, obstruction, and infertility, but also imposes a high economic burden on healthcare systems worldwide. OBJECTIVE: The aim of this review was to evaluate the adhesion prevention potential of all currently available adhesion barriers for gynecological surgery. EVIDENCE ACQUISITION: We systematically searched MEDLINE and CENTRAL databases for randomized controlled trials (RCTs) on the use of adhesion barriers as compared with peritoneal irrigation or no treatment in gynecological surgery. Only RCTs with second-look surgery to evaluate adhesions in the pelvic/abdominal (but not intrauterine) cavity were included. RESULTS: We included 45 RCTs with a total of 4,120 patients examining a total of 10 unique types of barriers in second-look gynecological surgery. While RCTs on oxidized regenerated cellulose (significant improvement in 6 of 14 trials), polyethylene glycol with/without other agents (4/10), hyaluronic acid and hyaluronate + carboxymethylcellulose (7/10), icodextrin (1/3), dextran (0/3), fibrin-containing agents (1/2), expanded polytetrafluoroethylene (1/1), N,O-carboxymethylchitosan (0/1), and modified starch (1/1) overall showed inconsistent findings, results for expanded polytetrafluoroethylene, hyaluronic acid, and modified starch yielded the greatest improvements regarding adhesion reduction at 75%, 0-67%, and 85%, respectively. CONCLUSIONS AND RELEVANCE: Best results for adhesion prevention were reported after applying Gore-Tex Surgical Membrane, hyaluronic acid, and 4DryField®. As Gore-Tex Surgical Membrane is nonabsorbable, it is associated with a greater risk of new adhesion formation due to second-look surgery to remove the product. 4DryField® yielded the greatest improvement in adhesion score compared to all other barrier agents (85%). For better comparability, future studies should use standardized scores and put more emphasis on patient-reported outcome measures, such as pain and infertility.

OBJECTIVE: To compare the cost-effectiveness of serial non-echo planar diffusion weighted MRI (non-EP DW MRI) versus planned second look surgery following initial canal wall up tympanomastoidectomy for the treatment of cholesteatoma. METHODS: A decision-analytic model was developed. Model inputs including residual cholesteatoma rates, rates of non-EP DW MRI positivity after surgery, and health utility scores were abstracted from published literature. Cost data were derived from the 2022 Centers for Medicare and Medicaid Services fee rates. Efficacy was defined as increase in quality-adjusted life year (QALY). One- and 2-way sensitivity analyses were performed on variables of interest to probe the model. Total time horizon was 50 years with a willingness to pay (WTP) threshold set at $50 000/QALY. RESULTS: Base case analysis revealed that planned second-look surgery ($11 537, 17.30 QALY) and imaging surveillance with non-EP DWMRI ($10 439, 17.26 QALY) were both cost effective options. Incremental cost effectiveness ratio was $27 298/QALY, which is below the WTP threhshold. One-way sensitivity analyses showed that non-EP DW MRI was more cost effective than planned second-look surgery if the rate of residual disease after surgery increased to 48.3% or if the rate of positive MRI was below 45.9%. A probabilistic sensitivity analysis at WTP of $50 000/QALY found that second-look surgery was more cost-effective in 56.7% of iterations. CONCLUSION: Non-EP DW MRI surveillance is a cost-effect alternative to planned second-look surgery following primary canal wall up tympanomastoidectomy for cholesteatoma. Cholesteatoma surveillance decisions after initial canal wall up tympanomastoidectomy should be individualized. LEVEL OF EVIDENCE: V.

BACKGROUND: Malignant ovarian germ cell tumors (MOGCT) are rare in children. Surgery with or without chemotherapy is the primary treatment approach. This study aimed to analyze the impact of primary and delayed surgery on surgical morbidity and outcomes. Second-look surgery after inadequate surgical staging and the various components of surgical staging were also evaluated. METHODS: Children below 15 years with MOGCT treated between 2006 and 2022 were analyzed. A comparison of patients undergoing primary, delayed, and second-look surgery was performed. RESULTS: 118 patients with a median age of 12 (0.11-15) years were eligible. Forty patients underwent primary, 51 delayed, and 27 second-look surgeries. Overall complications, including tumor rupture, blood loss, and adjacent organ removal, were significantly higher in the primary compared to the delayed surgery group (p = 0.0001). Second-look surgery conceded more blood loss (p = 0.0001), extended duration (p = 0.03), and complications (p = 0.004) than delayed surgery. The compliance with surgical guidelines was 100% for most components, with a positive yield rate of 10-80%. At a median follow-up of 5.2 years, the 5-year event-free survival (EFS) and overall survival (OS) for the entire cohort are 86% and 89%, respectively. The OS and EFS did not differ by the timing of surgery, although the second-look surgery demonstrated relatively inferior outcomes consequential to initial suboptimal surgery. CONCLUSIONS: MOGCT shows favorable outcomes. Delayed surgery after chemotherapy in appropriately selected patients minimizes the morbidity of surgery with similar outcomes compared to primary surgery. An optimal initial surgery is essential since second-look surgery produces significant morbidity. Prognosis Study, Level II evidence.

PURPOSE: The purpose of this study is to identify the rate and risk factors for a reoperation for arthrofibrosis following primary anterior cruciate ligament (ACL) reconstruction. METHODS: Prospective data recorded in the New Zealand ACL Registry were cross-referenced with data from the Accident Compensation Corporation (ACC). Primary ACL reconstructions performed between April 2014 and May 2021 were analysed. The ACC database was used to identify patients who underwent a reoperation for a diagnosis of arthrofibrosis. Multivariable survival analysis was performed to compute adjusted hazard ratios (aHR) and 95% confidence intervals. RESULTS: A total of 12,296 primary ACL reconstructions were analysed, of which 230 underwent a reoperation for arthrofibrosis (1.9%) at a mean follow-up of 3.6 years. A higher risk of arthrofibrosis was observed in females (aHR = 1.76, p = 0.001), patients with a history of previous knee surgery (aHR = 1.82, p = 0.04) and when a transtibial drilling technique was used (aHR = 1.53, p = 0.03). ACL reconstruction >6 months after injury had the lowest rate of arthrofibrosis (1.3%, aHR = 0.45, p = 0.01). There was no difference in risk between early surgery within 6 weeks versus delayed surgery between 6 weeks and 6 months after injury (2.9% versus 2.1%, aHR = 0.78, not significant). CONCLUSION: Female sex, previous knee surgery and a transtibial drilling technique increased the risk of reoperation for arthrofibrosis. Early surgery within 6 weeks of injury was not associated with an increased risk when compared with surgery between 6 weeks and 6 months after injury. LEVEL OF EVIDENCE: Level III.

This study compared cartilage regeneration outcomes in knee osteoarthritis (OA) using allogeneic human umbilical cord blood-derived mesenchymal stem cell (hUCB-MSC) implantation and microdrilling with high tibial osteotomy (HTO). Fifty-four patients (60 knees) were included: 24 (27 knees) in the hUCB-MSC group and 30 (33 knees) in the microdrilling group. Both groups showed significant improvements in pain and functional scores at 6, 12, and 24 months compared to baseline. At 24 months, the hUCB-MSC group had significantly improved scores. Arthroscopic assessment at 12 months revealed better cartilage healing in the hUCB-MSC group. In subgroup analysis according to the defect site, hUCB-MSC implantation showed superior cartilage healing for anterior lesions. In conclusion, both treatments demonstrated effectiveness for medial OA. However, hUCB-MSC implantation had better patient-reported outcomes and cartilage regeneration than microdrilling. The study suggests promising approaches for cartilage restoration in large knee defects due to OA.

OBJECTIVE: To evaluate whether canal wall-up (CWU) tympanomastoidectomy with diffusion-weighted magnetic resonance imaging (DW-MRI) is a cost-effective method of treating cholesteatoma compared with CWU with second-look surgery. DESIGN AND SETTING: Cost-effectiveness analysis was conducted using a Markov state transition model. The simulation model adhered to the Panel Recommendations on Cost-Effectiveness in Health and Medicine established by the US Public Health Service. One-way and Monte Carlo probability sensitivity analyses were conducted for validation. INTERVENTIONS: Tympanomastoidectomy with DW-MRI versus tympanomastoidectomy with second-look surgery. MAIN OUTCOME MEASURES: Effectiveness and health utility were measured using quality-adjusted life years (QALYs). Costs were derived from Medicare reimbursement using the perspective of the payer. Probabilities for outcomes and complications were taken from existing literature. Cost-effectiveness was assessed using the incremental cost-effectiveness ratio. RESULTS: With base case analysis, the total cost was $15,069 when treated with CWU and second-look surgery versus $13,126 when treated with CWU and DW-MRI. The second-look treatment pathway yielded 17.05 QALYs, whereas the DW-MRI pathway yielded 16.91 QALYs in terms of health benefit accrued across the lifetime of the patient. The cost-effectiveness incremental cost-effectiveness ratio was $21,800/QALY. Using the conventional $50,000 willingness-to-pay threshold, second-look surgery was the more cost-effective approach 63.7% of the time by simulation. CONCLUSIONS: Both treatment pathways were found to be cost-effective, with second-look surgery incrementally cost-effective 63.7% of the time. Assumptions were validated by one-way and Monte Carlo probability sensitivity analysis. PROFESSIONAL PRACTICE GAP AND EDUCATIONAL NEED: There is ample variation in treatment pathways regarding usage of DW-MRI and second-look surgery for cholesteatoma. LEARNING OBJECTIVE: To evaluate the cost-effectiveness of DW-MRI and second-look surgery approaches, accounting for health-related quality-of-life outcomes and costs for the duration of the patient lifetimes. DESIRED RESULT: To inform the discussion on the treatment for cholesteatoma given emergent noninvasive technologies.Level of Evidence: Level III.Indicate IRB or IACUC: Exempt.

OBJECTIVE: The objective of this study was to understand applicant perspectives on in-person and virtual otolaryngology residency interviews. STUDY DESIGN: Survey study. SETTING: Otolaryngology residency applicants who were interviewed during 2022-2023. METHODS: Survey sent to all otolaryngology residency applicants who interviewed during the 2022-2023 interview season. RESULTS: A total of 499 applicants were surveyed with 150 responses (30%). Approximately 48.3% of respondents were offered an in-person interview with 78.9% accepting the offer. Of those who did not accept, reasons included not wanting to travel (21.1%) and time conflicts (15.5%). When comparing virtual versus in-person interviews, those who attended virtual interviews were more likely to disagree that they connected with residents (P = .02) and that they had an improved perspective of the program (P = .002). The majority of applicants agreed that virtual interviews are more inclusive and equitable than in-person interviews (70.4%). When asked which interview style applicants would prefer, 63.1% of applicants preferred an in-person interview when compared to virtual with a second look option (29.5%) and virtual (7.4%). Respondents who self-identified as being underrepresented in medicine were less likely to choose in-person as their preferred interview format (P = .01) and were more likely to decline an in-person interview offer due to monetary limitations (P = .04). CONCLUSIONS: Applicants indicated dissatisfaction with connecting with residents and improving their perspective of the program when in a virtual setting. Applicants felt that virtual interviews were more equitable, but that if the barriers to equity were lessened then they would prefer in-person interviews.

PURPOSE: To evaluate the outcome of a routine postoperative endoscopic micro-debridement of granulation tissue after stentless transnasal endoscopic repair of choanal atresia (CA). METHODS: This prospective case series included congenital CA patients who underwent stentless transnasal endoscopic repair, followed by an endoscopic second look and micro-debridement of granulation tissue at 1-2 weeks post-repair. Patients were followed every three months for assessment of nasal airway symptoms and objective evaluation by flexible nasolaryngoscopy. RESULTS: Sixteen CA patients (8 bilateral and 8 unilateral) underwent surgical repair (12 primary and 4 revisions). The median age was 13 days (range 1 day-6 months) in bilateral and 3 years (range 7 months-15 years) in unilateral atresia. The mean follow-up was 1.5 years (range 1 year-3 years). In primary procedures, the obstruction was bony-membranous in 7 cases and bony in 5 cases. The mean interval time between the CA repair and re-examination was 10.75 days (range 6-18 days). Clinically significant neochoanal restenosis was not encountered. CONCLUSIONS: Re-examination under general anesthesia with endoscopic micro-debridement of granulation tissue is a safe, potentially effective adjunct when done during the proliferative phase of neochoanal wound healing. This procedure might help in maintaining neochoanal patency by remodeling tissue healing process. Large-scale, long-term cohort studies are imperative.

OBJECTIVES: Lung volume reduction surgery (LVRS) has proven an effective treatment for emphysema, by decreasing hyperinflation and improving lung function, activity level and reducing dyspnoea. However, postoperative air leak is an important complication, often leading to reoperation. Our aim was to analyse reoperations after LVRS and identify potential predictors. METHODS: Consecutive single-centre unilateral VATS LVRS performed from 2017 to 2022 were included. Typically, 3-5 minor resections were made using vascular magazines without buttressing. Data were obtained from an institutional database and analysed. Multivariable logistic regression was used to identify predictors of reoperation. Number and location of injuries were registered. RESULTS: In total, 191 patients were included, 25 were reoperated (13%). In 21 patients, the indication for reoperation was substantial air leak, 3 patients bleeding and 1 patient empyema. Length of stay (LOS) was 21 (11-33) vs. 5 days (3-11), respectively. Only 3 injuries were in the stapler line, 13 within < 2cm and 15 injuries were in another site. Multivariable logistic regression analysis showed that decreasing DLCO increased risk of reoperation, OR 1.1 (1.03, 1.18, P = 0.005). Resections in only one lobe, compared to resections in multiple lobes, were also a risk factor OR 3.10 (1.17, 9.32, P = 0.03). Patients undergoing reoperation had significantly increased 30-day mortality, OR 5.52 (1.03, 26.69, P = 0.02). CONCLUSIONS: Our incidence of reoperation after LVRS was 13% leading to prolonged LOS and increased 30-day mortality. Low DLCO and resections in a single lobe were significant predictors of reoperation. The air leak was usually not localized in the stapler line.

BACKGROUND: Surgical site drainage is important to prevent hematoma, seroma, and abscess formation. However, the placement of drain placement also predispose patients to several postoperative complications. The aim of this study is to clarify the risk-benefit profile of surgical drain placement. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Procedure-Targeted Databases were used to identify patients who underwent hepatectomy, pancreatectomy, nephrectomy, cystectomy, and prostatectomy. Patients who underwent each procedure were divided into 2 groups based on intraoperative drain placement. Propensity score-matched cohorts of these 2 groups were compared in terms of postoperative adverse events, readmission, reoperation, and length of stay. RESULTS: Hepatectomy patients with drains experienced organ space infections (P < .001), sepsis (P < .001), and readmission (P = .021) more often than patients without drains. Patients who underwent pancreatectomy and had drains placed experienced wound dehiscence less frequently than those without drains (P = .04). For hepatectomy, pancreatectomy, nephrectomy, and prostatectomy populations, patients with drains had longer lengths of stay (P < .05). Matched populations across all procedures did not differ in terms of reoperation rate. DISCUSSION: Prophylactic surgical drain placement may be associated with increased infectious complications and prolonged length of stay. Further studies are needed to elucidate the complete adverse event profile of surgical drains. Nonetheless, outcomes may be improved with better patient selection or advancements in drain technology.

INTRODUCTION AND OBJECTIVES: Transurethral resection of bladder tumor (TURBT) is crucial in the treatment of bladder tumors and when incorrectly performed can cause staging mistakes. To avoid these errors, a second resection is recommended in selected cases. The aim of this study is to evaluate the surgeon's ability to predict histologically complete primary resection of newly diagnosed bladder tumors avoiding the need for a second TURBT. METHODS: This is a prospective, observational study involving 47 consecutive patients with newly diagnosed bladder tumors who had previously undergone primary TURBT, and met EAU criteria for second-look TURBT. Second-look TURBT specimens were analyzed for routine histological assessment and compared with the surgeon's impression of the tumor at initial resection. RESULTS: Of 91 patients submitted to primary TURBT, 47 met the criteria for second-look TURBT. Second-look specimens revealed residual disease in 20.9% of patients and 3 (6.4%) of patients showed upstaging disease. The sensitivity of a senior to detect disease on second-look TURBT in relation to muscle invasion was 75%, and the specificity was 85%. CONCLUSIONS: Second-look TURBT is crucial in the treatment of bladder cancer and cannot be replaced by a surgeon's opinion, so international recommendations should be followed. Supervision of less experienced surgeons is a cornerstone.

INTRODUCTION: The relationship between socioeconomic status and neurosurgical outcomes has been investigated with respect to insurance status or median household income, but few studies have considered more comprehensive measures of socioeconomic status. This study examines the relationship between Area Deprivation Index (ADI), a comprehensive measure of neighborhood socioeconomic disadvantage, and short-term postoperative outcomes after lumbar fusion surgery. METHODS: 1861 adult patients undergoing single-level, posterior-only lumbar fusion at a single, multihospital academic medical center were retrospectively enrolled. An ADI matching protocol was used to identify each patient's 9-digit zip code and the zip code-associated ADI data. Primary outcomes included 30- and 90-day readmission, emergency department visits, reoperation, and surgical complication. Coarsened exact matching was used to match patients on key demographic and baseline characteristics known to independently affect neurosurgical outcomes. Odds ratios (ORs) were computed to compare patients in the top 10% of ADI versus lowest 40% of ADI. RESULTS: After matching (n = 212), patients in the highest 10% of ADI (compared to the lowest 40% of ADI) had significantly increased odds of 30- and 90-day readmission (OR = 5.00, P < 0.001 and OR = 4.50, P < 0.001), ED visits (OR = 3.00, P = 0.027 and OR = 2.88, P = 0.007), and reoperation (OR = 4.50, P = 0.039 and OR = 5.50, P = 0.013). There was no significant association with surgical complication (OR = 0.50, P = 0.63). CONCLUSIONS: Among otherwise similar patients, neighborhood socioeconomic disadvantage (measured by ADI) was associated with worse short-term outcomes after single-level, posterior-only lumbar fusion. There was no significant association between ADI and surgical complications, suggesting that perioperative complications do not explain the socioeconomic disparities in outcomes.

BACKGROUND AND PURPOSE: The Lubinus SP2 stem has been associated with a very low risk of periprosthetic femoral fractures (PPFFs). We aimed, primarily, to study the radiographic morphology of PPFFs close to a Lubinus SP2 stem. Secondarily, we analyzed whether higher reoperation rate was correlated to the revision method chosen or to the characteristics of the fracture and of the bone. PATIENTS AND METHODS: The study included 156 femoral fractures close to a Lubinus cemented stem. These fractures were treated in 40 hospitals in Sweden between 2006 and 2011 and were followed up until 2019. Data from the Swedish Arthroplasty Register was used. Medical records and radiographs were studied. The fractures were classified according to the Vancouver classification. The fracture location and anatomy were delineated. We also measured the remaining attachment index (RAI) and the canal thickness ratio. RESULTS: Vancouver type C (n = 101) and spiral fractures (n = 67, 41 in Vancouver C and 26 in Vancouver B) were the most common fracture types. 4 fractures were avulsion of the greater trochanter. The remaining 51 fractures occurred around the stem (B1: 25, B2: 16, and B3: 10). B fractures were more commonly reoperated on (18 of 51, 35%) than type C fractures (11 of 101, 11%, P = 0.001). In most femurs with type B3 fracture, the fracture line covered an area only around the stem, but in all B1 and in 11 of 16 B2 fractures, it was extended even distal to the stem. ORIF instead of stem revision in B2 fractures, use of short stems or plates, and inadequate reduction of the fractures were risk factors for subsequent reoperations. CONCLUSION: The higher reoperation rate in type B fractures, compared with fractures distal to the stem, could be caused by their higher degree of complexity and reduced capacity for healing in the region around the stem.

OBJECTIVE: Percutaneous cement discoplasty (PCD) was introduced to treat symptomatic vertical instability of the lumbar spine in a minimally invasive way. The aim of the present study was to analyze the complication pattern after PCD and to identify factors that predict the chance of cement leakage, reoperation, and length of hospital stay (LOS). METHODS: patients were treated with PCD within the study period. Clinical features and complications were analyzed by applying descriptive statistics, whereas perioperative factors predictive of cement leakage, reoperation, and LOS were identified by regression models. RESULTS: Cement leakage rate was 30.4% in the total cohort; however, only fifth of them were symptomatic. Cement leakage itself did not have a significant influence on clinical outcome. Other complications and nonsurgical adverse events were registered only in 2.0% of cases. Age, subcutaneous fat tissue thickness, low viscosity cement, lower level of surgeon's experience and the number of operated levels were identified as risk factors of cement leakage (P < 0.01; c-index = 0.836). Type of procedure, Charlson comorbidity score, reoperation, and nonsurgical adverse events significantly increased the LOS (P < 0.01). Cement leakage, early surgical practice, and increased subcutaneous fat tissue thickness were risk factors for reoperation (P < 0.01; c-index = 0.72). CONCLUSIONS: PCD is a relatively safe and effective procedure for treating spinal instability caused by advanced-stage disc degeneration characterized by vacuum phenomenon. Cement leakage is not uncommon but is only a radiologic complication without clinical consequences in most cases. On the other hand, it can increase the LOS and is a significant risk factor for reoperation.

BACKGROUND: Parkinson disease (PD) is a neurodegenerative disorder that manifests with postural instability and gait imbalance. Correction of spinal deformity in patients with PD presents unique challenges. METHODS: The PearlDiver database was queried between 2010 and 2020 to identify adult patients with spinal deformity before undergoing deformity correction with posterior spinal fusion. Two cohorts were created representing patients with and without a preoperative diagnosis of PD. Outcome measures included reoperation rates, surgical technique, cost, surgical complications, and medical complications. Multivariable logistic regression adjusting for Charlson Comorbidity Index, age, gender, 3-column osteotomy, pelvic fixation, and number of levels fused was used to assess rates of reoperation and complications. RESULTS: In total, 26,984 patients met the inclusion criteria and were retained for analysis. Of these patients, 725 had a diagnosis of PD before deformity correction. Patients with PD underwent higher rates of pelvic fixation (odds ratio [OR], 1.33; P < 0.001) and 3-column osteotomies (OR, 1.53; P < 0.001). On adjusted regression, patients with PD showed increased rates of reoperation at 1 year (OR, 1.37; P < 0.001), 5 years (OR, 1.32; P < 0.001), and overall (OR, 1.33; P < 0.001). Patients with PD also experienced an increased rate of medical complications within 30 days after deformity correction including deep venous thrombosis (OR, 1.60; P = 0.021), pneumonia (OR, 1.44; P = 0.039), and urinary tract infections (OR, 1.54; P < 0.001). Deformity correction in patients with PD was associated with higher 90-day cost (P = 0.007). CONCLUSIONS: Patients with PD undergoing long fusion for deformity correction are at significantly increased risk of 30-day medical complications and revision procedures after 1 year, controlling for comorbidities, age, and invasiveness. Surgeons should consider the risk of complications, subsequent revision procedures, and increased cost.

Revision total knee arthroplasty (TKA) patients have a lower survival rate and lower post-surgical outcomes compared to primary TKA patients. Infection and aseptic loosening are the most common reasons for revision and re-revision TKAs, with infection accounting for nearly half of re-revision cases. To prevent infection, patient optimization addressing obesity, diabetes, malnutrition, and smoking cessation is crucial. Advancements in irrigation solutions, antibiotic-impregnated bone fillers, bacteriophage therapy, and electrochemical therapy hold promise for preventing infection. Technical strategies such as obtaining sufficient component fixation, joint line restoration, and using robot assistance may improve revision TKA outcomes. As the burden of revision TKA continues to rise, substantial efforts remain for mitigating future revision TKAs and their associated complications.

BACKGROUND: The timing of bleeding after bariatric surgery and subsequent management (characterized as surgical versus non-surgical (i.e., interventions including endoscopic or interventional radiology approaches)) has not been thoroughly studied. As such, we sought to describe the rates of reoperation or non-operative intervention after bleeding following sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). METHODS: The Metabolic and Bariatric Accreditation and Quality Improvement Program (MBSAQIP) database was queried between 2015 and 2018 for any bleeding after SG or RYGB and subsequent reoperation or non-operative intervention. Multivariable Fine-Gray models were used to compare the hazard of reoperation/non-operative intervention. Multivariable generalized linear regression models were used to test the number of subsequent reoperations/non-operative interventions depending on initial management. RESULTS: 6251 patients with bleeding after SG or RYGB were identified, of which 2653 patients underwent subsequent procedures (n = 1375 [51.83%] RYGB index procedure, n = 1278 [48.17%] SG index procedure). 1892 (71.32%) and 761 (28.68%) patients had reoperation and non-operative intervention, respectively. For patients who developed bleeding, SG was associated with significantly higher reoperation risk, while RYGB was associated with significantly higher risk of non-operative intervention. Early bleeding was associated with significantly increased risk of reoperation and decreased risk of non-operative intervention, regardless of initial procedure. The total number of subsequent reoperations/non-operative interventions did not differ significantly depending on whether the patients had non-operative intervention or reoperation first [ratio 1.01, 95% CI (0.75, 1.36), p value 0.9418]. CONCLUSION: Patients after SG who experience bleeding are more likely to undergo reoperation than RYGB patients. On the other hand, patients with bleeding after RYGB are more likely to undergo non-operative intervention compared to SG patients. Early bleeding is associated with higher risk of reoperation and lower risk of non-operative intervention both after SG and RYGB. The initial approach did not play a role in the total number of subsequent reoperations/non-operative interventions.

BACKGROUND AND PURPOSE: In existing studies on fasttrack unicompartmental knee arthroplasty (UKA), the majority of surgeries are medial. There are substantial differences between lateral and medial UKA, which is why outcomes cannot automatically be compared. To gain information on the feasibility and safety of fast-track protocols in lateral UKAs, we investigated length of stay (LOS) and early complications after lateral UKA, performed using a fast-track protocol in well-established fast-track centers. PATIENTS AND METHODS: We retrospectively evaluated prospectively collected data on patients undergoing lateral UKA in a fast-track setup from 2010 to 2018 at 7 Danish fast-track centers. Data on patient characteristics, LOS, complications, reoperations, and revisions was analyzed using descriptive statistics. Safety and feasibility were defined as complication and reoperation rates within 90 days comparable to non-fast track lateral UKA or fast-track medial UKA. RESULTS: We included 170 of patients with a mean age of 66 (SD 12) years. Median LOS was 1 day (interquartile range 1-1), which was unchanged from 2012-2018. 18% were discharged on the day of surgery. Within 90 days, 7 patients experienced medical complications and 5 patients experienced surgical complications. 3 patients underwent reoperation, 2 were soft tissue revisions and the third was removal of an exostosis due to catching of the patella. 1 patient was revised due to a bearing dislocation. CONCLUSION: Our findings suggest that lateral UKA in a fast-track setting is feasible and safe.

Administrative claims databases have great power for clinical research, especially when used to evaluate trends from large cohorts. However, it should be noted that in these types of studies, patients in a database are treated at different time points, so some patients do not reach long-term follow-up by the end of the study period. Thus, such analyses require more stringent inclusion and exclusion criteria, which may significantly reduce the size of the included cohort. Recent research using the PearlDiver database has reported that the 5-year secondary surgery rate after hip arthroscopy is 4.9%. However, our research using the PearlDiver Mariner data set showed a 2-year reoperation rate after hip arthroscopy of 15%, and although most secondary surgical procedures occur within the first 2 years after hip arthroscopy, the 5-year reoperation rate may be higher. Readers should remain alert to the limitations of large database analyses.
