BN SO39 - Laparoscopic Release of Median Arcuate Ligament Syndrome: A Case Series

Abstract Background Median arcuate ligament syndrome (MALS) is a recognized, but rare condition, which is characterized by compression of the celiac artery and ganglion by median arcuate ligament. The entity often presented with chronic post-prandial abdominal pain, vomiting, and weight loss. These patients often undergo comprehensive investigation prior to diagnosis of MALS. This report presents our experience and short-term outcomes of patients with laparoscopic release of MALS at our center. Method Between 2022-2024, five patients with MALS underwent laparoscopic release at a tertiary HPB center under a single surgeon (TS). Data on patient demographics, presenting symptoms and duration, preoperative diagnostic tests, intraoperative findings and complications, postoperative complications, symptom recurrence and follow-up were prospectively maintained. All patients were discussed at a tertiary Vascular and HPB MDT; MALS was confirmed on US doppler (USD) and CT angiogram (CTA) (fish-hook type configuration of Celiac Truck with post-stenotic dilatation). Results Two male and three female patients, with a median (range) age of 41 (25-70) years, underwent laparoscopic MALS release. The median (range) preoperative symptom duration was 54 (24-67) months, with most common presentation of post-prandial abdominal pain and weight loss. The median (range) BMI was 19.61 (18.30-17.82). The median (range) operative time was 313 (166-330) minutes. One patient required conversion to open due to bleeding from celiac trunk. The median (range) LOS was 7 (4-7) days. No postoperative complications occurred. The median follow-up was 10 months. One patient re-experienced abdominal pain, with no evidence of recurrence on USD and CTA. Conclusion Median Arcuate Ligament Syndrome should be considered as a differential in patients presenting with chronic post-prandial abdominal pain and weight loss. Thorough investigation (USD and CTA) along with discussion at Vascular MDT should be undertaken. Laparoscopic release of MALS is a safe and effective treatment option in this cohort.

Severe Corneal Flattening After Endothelial Keratoplasty: Collagen Compaction Syndrome.

The purpose of this study was to present a case series of patients with extreme corneal flattening after uneventful endothelial keratoplasty (EK): collagen compaction syndrome. Four patients (2 men, 2 women, mean age 64.8 ± 11.8 years) underwent successful EK after a period of chronic corneal edema (4-7.5 months): 3 received Descemet membrane endothelial keratoplasty after unsuccessful Descemet stripping only for Fuchs dystrophy and 1 received Descemet automated endothelial keratoplasty after prolonged pseudophakic bullous keratopathy. All patients developed significant corneal flattening, affecting their vision and inducing a large hyperopic refractive outcome, best-corrected visual acuities ranging from 20/40 to 20/200. Chronic corneal edema may result in severe corneal flattening after EK. Preoperative duration of stromal edema might affect the outcome of EK and should, therefore, be considered in the timing of surgery. In cases of dense focal edema, including post-Descemet stripping only surgery, rescue treatment at week 8 should be considered.

Surgical treatment outcomes and risk factors for post-TB lung disease.

This study aims to investigate the effectiveness and safety of surgical treatment for post-TB lung disease (PTLD) and to analyse its risk factors. Data were collected from 268 patients who underwent pulmonary resection for TB in Xi'an Chest Hospital, Xi'an, Shaanxi, China, between January 2014 and December 2023. The efficacy and safety of the three groups were compared, and the TB group was used as the control group to analyse the risk factors of PTLD. The results indicated the three groups in intraoperative blood loss, post-operative drainage volume, post-operative complications, and post-operative hospital stay also varied significantly among the three groups (all P < 0.01). Additionally, factors such as pre-operative anti-TB therapy duration (OR = 1.02, P = 0.007), age (OR = 1.03, P = 0.030), and comorbid diabetes mellitus (OR = 3.00, P = 0.046) were identified as significant contributors to PTLD. While pre-operative haemoptysis demonstrates a statistically significant correlation with both precursor PTLDs, this association likely reflects the clinical expression of the underlying disease process. The study confirms that surgery for PTLD is safe and efficacious. Patients with advanced age, an extended duration of pre-operative anti-TB therapy, comorbid diabetes mellitus and pre-operative haemoptysis should maintain vigilance regarding the potential development of PTLD.

Longer preoperative fluid resuscitation decreased anesthetic fluid interventions in 297 dogs undergoing surgery for gastrointestinal foreign body obstruction.

The objectives were to (1) compare the impact of preoperative fluid resuscitation on anesthetic parameters and interventions and (2) assess the impact of preoperative resuscitation duration on the integrity of intestinal tissue and postoperative complications in dogs with gastrointestinal foreign body obstruction. Medical records from 1 academic hospital were reviewed for 297 client-owned dogs that underwent gastrointestinal foreign body obstruction surgery between May 2017 and August 2022. Data collected included the following: signalment, preoperative fluid resuscitation, surgical findings, anesthetic parameters and interventions, postoperative complications, and timing of the first meal. Variables for preoperative length of fluid resuscitation (hours), total preoperative fluid bolus (mL/kg), and preoperative fluid rate (mL/kg/d) were changed to categorical variables. Associations between anesthetic interventions, postoperative outcomes, preoperative fluid resuscitation length, and total fluid bolus were assessed with ordered logistic regression. Shorter preoperative fluid resuscitation length was associated with higher anesthetic fluid rates (P = .033) and fluid boluses performed (P = .023). Increased total volume of preoperative fluid boluses was associated with anesthetic synthetic colloid use (P = .028). There was insufficient evidence to claim an association between the impact of preoperative fluid resuscitation length and intestinal wall compromise (perforation, P = .912; enterectomy performed, P = .711). Shorter preoperative fluid resuscitation was associated with increased anesthetic fluid interventions but not the need for more complex surgeries. Longer fluid resuscitation periods are associated with fewer anesthetic interventions in dogs.

Surgical treatment of infective endocarditis: some experiences at the Heart Institute, Ho Chi Minh City

Objective: To determine the factors associated with in-hospital mortality and the appropriate timing of operation in patients with infective endocarditis undergoing cardiac surgery. Methods: Cross-sectional study in patients admitted to the Heart Institute from 01/01/2021 to 31/12/2023 who had a diagnosis of infective endocarditis and had undergone cardiac surgery within the same hospital admission. Results: 128 patients (87 men, age: 44,8 ± 15,8 years) were enrolled. Streptococcus (37,5%) and Enterococcus (12,5%) were the most frequent pathogen agents. Aortic valve replacement and mitral valve replacement or repair were the main procedures. In-hospital mortality was 6.3%. The factors associated with in-hospital mortality included the presence of a prosthetic valve or pulmonary artery graft, abscess and/or fistula, and severe heart failure necessitating urgent operation. Preoperative duration of antibiotic therapy &gt;21 days vs ≤21 days, and &gt;14 days vs ≤14 days had no influence on in-hospital mortality. There was no infective endocarditis relapse. While waiting for cardiac surgery, the cumulative incidence of embolic events rose markedly beginning from the 3rd week after antibiotic therapy initiation. Conclusions: Factors associated with in-hospital mortality should be taken into account in the preoperative risk assessment. Patients with infective endocarditis who have indication for cardiac surgery and favorable response to antibiotic therapy should be operated after 2 weeks of antibiotic treatment.

Medium- to Long-term Outcomes of Fasciotomy for Chronic Exertional Compartment Syndrome: A 6-Year Mean Follow-up Study.

Operative treatment of chronic exertional compartment syndrome (CECS) with fasciotomy is effective for symptomatic resolution, but outcomes at medium- to long-term follow-up are unclear. Patients will have favorable satisfaction at medium- to long-term follow-up and a high return to sport (RTS) rate after fasciotomy for treatment of CECS. Cross-sectional. Level 3. Retrospective review of patients who underwent fasciotomy for treatment of CECS from 2010 to 2021. Outcomes were assessed using Tegner Activity Scale, symptom resolution, patient satisfaction, return to activities, and EQ-5D-5L survey. Fifty patients (23 male and 27 female) were included. Mean age at time of surgery was 29.0 ± 11.6 years with mean follow-up 6.0 ± 2.3 years (range, 2.6-10.9). Tegner activity scores at final follow-up were improved compared with symptom onset (mean, 5.2 vs 3.3; P < 0.01). Increased preoperative symptom duration correlated with decreased RTS (β = -0.447; P = 0.01) and return to work (RTW) (β = -0.572; P = 0.01). Patients with a previous psychiatric diagnosis (n = 15) had lower rates of RTS (β = -0.358; P = 0.03) and RTW (β = -0.471, P = 0.02). Mean time to RTS was 5.5 ± 6.1 months. Mean visual analogue scale satisfaction rate was 74.4; 36 (72.0%) patients would be willing to have their fasciotomy again. Patients with fasciotomy of 1 to 2 compartments had higher Tegner score at final follow-up (P = 0.02) than those who had fasciotomy of >3 compartments; 19 (38.0%) patients reported experiencing paresthesia after their operation. No patients experienced major complications. Medium- to long-term outcomes of patients with CECS treated with fasciotomy demonstrated high satisfaction levels and high RTS rate. However, rate of minor complications including paresthesia, swelling, and cramping was high.

Visual deterioration secondary to medial sphenoid wing meningioma: systematic assessment of patient-reported outcomes and factors contributing to recovery after surgical treatment.

Visual acuity (VA) constitutes an important outcome measure in surgery for medial sphenoid wing meningioma (SWM). This study aimed to assess the recovery of tumor-associated impairment of VA and its impact on patient-reported outcome measures (PROMs) as an indication of vision-related quality of life in patients who had undergone surgery for medial SWM. From 2009 to 2018, 153 consecutive patients with medial SWM underwent surgical treatment at the authors' institutions. Tumor-associated VA was evaluated both on admission and during postoperative follow-up examinations, using Snellen charts. Multivariable analysis was performed to identify independent predictors for postoperative improvement of VA. PROMs were collected based on the National Eye Institute 25-Item Visual Function Questionnaire. Of patients with medial SWM, 53 of 153 (35%) experienced preoperative impairment of VA. The median preoperative duration of visual symptoms was 12 (IQR 3-17) months for the entire study cohort. Multivariable analysis revealed a preoperative duration of visual symptoms ≤ 4 months to be independently associated with postoperative improvement of VA (p = 0.009). Evaluation of PROMs indicated a superior postoperative qualitative extent in the overall health (p = 0.027) and activities of daily living (p = 0.031) categories if preoperative duration of visual impairment was ≤ 4 months. The overall preoperative duration of tumor-related visual impairment significantly correlates to the extent of postoperative visual improvement as well as vision-related PROMs in medial SWM surgery. These results might aid in preoperative patient counseling and help optimize decision-making and preoperative estimation of long-term visual outcome.

DIAGNOSTIC ACCURACY OF BOEY SCORE TO PREDICT 30 DAYS MORTALITY IN PERFORATED PEPTIC ULCER PATIENTS

Perforated peptic ulcers remain a life-threatening condition despite advancements in surgical and medical treatments. Accurate risk stratification of patients can improve outcomes by guiding clinical decision-making. The Boey scoring system is widely used for predicting mortality in patients with perforated peptic ulcers, yet its diagnostic accuracy warrants further evaluation. Objective: This study aimed to evaluate the diagnostic accuracy of the Boey score in predicting 30-day mortality among patients with perforated peptic ulcers. Methods: This cross-sectional study was conducted at the Department of Surgical Unit VI, Civil Hospital Karachi, over a six-month period from December 7, 2020, to June 7, 2021. A total of 149 patients diagnosed with perforated peptic ulcers were included using non-probability consecutive sampling. The Boey score was calculated for each patient based on preoperative shock, comorbid illness, and duration of perforation &gt;24 hours. The primary outcome measure was 30-day mortality. Descriptive statistics were used to assess the frequency distribution of mortality, and the association between Boey score and mortality was analysed using appropriate statistical methods, with significance set at p &lt; 0.05. Results: The study included 149 patients, with a minimum age of 21 and a maximum age of 50. Of the total, 32 patients (21.5%) experienced 30-day mortality. Among patients with a Boey score of 1, 2.68% had 30-day mortality, and 0.67% of patients with a Boey score of 2 died. Patients with a Boey score of 3 had the highest mortality rate, with 18.1% of this group experiencing 30-day mortality. In contrast, 81.9% of patients with a Boey score of 1 to 3 survived beyond 30 days. Conclusion: The Boey scoring system demonstrated vital predictive accuracy for 30-day mortality in patients with perforated peptic ulcers. This scoring tool effectively identifies high-risk patients, allowing for timely and appropriate management. Despite modern treatment advances, perforated peptic ulcer remains associated with significant mortality, particularly in high-risk patients, as identified by the Boey score.

Appropriate antimicrobial prescribing for bacteriuria before urological procedures: A room for improvement

In the presence of a positive preoperative urine culture, the prescription of a preoperative antibiotic therapy is recommended. The choice of antibiotic therapy and prescription are usually made by the urologist or the general practitioner (GP). The objective of the treatment is urinary sterilization rather than parenchymal treatment, and the treatment choice is key to reduce selective pressure and antimicrobial resistance. The objective of this study was to evaluate prescription patterns made by urologists and GPs, then to compare the antibiotics chosen by urologists or GPs to the “ideal” treatment defined by infectious diseases specialists. We retrospectively reviewed all positive preoperative urine cultures obtained between November 2022 and July 2023. Data pertaining to antibiotic prescriptions, including the duration of treatment, antibiotic class, and prescriber were collected. An infectious disease specialist conducted a blind review of each urine culture, providing recommendations for the most appropriate antibiotic based on their assessment. In cases of disagreement, a second infectious disease specialist conducted a similar evaluation. Out of 196 preoperative antibiotic prescriptions, 40 (20%) differed from the recommendations provided by the infectious disease specialist, with 39 involving the use of overly broad-spectrum antibiotics. Both infectious disease specialists yielded congruent recommendations in all cases. Notably, in 50% of these instances, the preoperative antibiotic treatment duration unduly exceeded 48hours. A statistically significant increase (4.84days vs. 2.99days) in preoperative treatment duration was observed when a GP was the prescriber (P<0.001). There is room for improvement of urologists’ antibiotic prescription practices to reduce the ecological impact on the patient's microbiota and on a global scale. The delegation to GPs resulted in unjustified longer treatment durations and should be avoided without dedicated training. Level of evidence4.

Ultrasound assessment of gastric content in elective surgery

Objective: To determine the prevalence of patients with ultrasound signs of a full stomach during surgery at the Sominé Dolo Hospital in Mopti. Methodology: Observational study investigated prospective, single-center over a period of one month include patients in surgery program aged 18 to 85 years. Our data was collected on individual survey sheets and analysed with the Epi info7 software. Result: Out of a total of 140 patients, 41 patients were included in our study, i.e. a frequency of 29.28%. The mean age of patients was 38 years +/-17. The average body mass index was 23+/- 4.65. Females predominated: 60.98% (n=25) compared to 39.02% (n=16) for males, with a sex ratio of 0.6/1. The ASA classification was rated at II in 51.22% of patients (n=21). The gastric antrum was visualized in 40 patients, i.e. an ultrasound sensitivity of 97.56%, of which seven (07) were difficult to see and not visualized in one patient. We found a relationship between high BMI and difficulty in visualizing gastric contents (P-value = 0.00001), but no relationship was found between BMI and Perlas score (P-Value = 0.75411). The Perlas score was rated at 0 in 85% (n=34), fluid content was found in 12.5% (n=5) of patients while one patient had solid content. Patients observed an estimated preoperative fasting duration of an average of 11 hours +/- 2.86. Conclusion: Despite the implementation of a preoperative fasting protocol, cases of full stomachs are still to be feared and the ultrasound at the bedside of patients is a simple, quick examination to best adjust the anesthesia protocol. Keywords: full stomach, gastric antrum, ultrasound, Perlas score, Mopti.

Does preoperative symptom duration affect outcomes following per oral endoscopic myotomy (POEM)?

Per oral endoscopic myotomy (POEM) is a safe therapy for the treatment of achalasia. Long-term effects of untreated achalasia include worsening dysmotility and disruptions in esophageal anatomy, i.e., tortuosity and dilation. We hypothesize that long-standing achalasia prior to intervention will have worse outcomes following POEM than in patients with symptoms for shorter duration. We retrospectively analyzed achalasia patients who underwent POEM at our institution from 2011 to 2023, categorizing them into symptom duration cohorts (< 1year, 1-3years, 4-10years, > 10years). Inclusion criteria comprised patients with documented achalasia diagnosis who received POEM treatment at our facility. Exclusion criteria encompassed individuals lacking data pertaining to achalasia diagnosis, the time frame before intervention, or those missing pre and postoperative Eckardt scores. POEM failure was defined as symptom recurrence, necessity for repeat intervention, or high postoperative Eckardt score. We compared demographic, preoperative, and postoperative outcomes across these cohorts, and employed multivariable logistic regression to explore the link between symptom duration and POEM response. During the study period, in our increased cohort 234 patients met inclusion criteria. 75 patients had symptoms for < 1year, 78 patients had symptoms from 1 to 3years, 47 patients had symptoms from 4 to 10years, and 34 patients had symptoms > 10years. Patient demographics such as age, sex, BMI, Charleson-Deyo-Comorbidity-Index, and diabetes did not differ amongst cohorts. High-resolution manometry data, including achalasia type, Median IRP, LES residual pressure, and Basal LES pressure did not differ between groups. Preoperative Eckardt scores ranged from 4 to 5 across groups (p 0.24). Patients endorsed an average of three total preoperative symptoms across groups (p 0.13). Patients with symptoms greater than 4years had significantly more endoscopic interventions prior to POEM (37% vs, 68% p .001). There was no significant difference in post-procedure mean Eckardt scores between cohorts. All cohorts experienced the same number of post-POEM symptoms. Post-POEM manometric measurements remained consistent across cohorts. Similarly, there were no significant differences in terms of symptom recurrence, requirement for repeat interventions, or repeat POEM among the cohorts. Multivariable logistic regression analysis determined achalasia symptoms greater than a decade did not result in increased odds of having a higher postoperative Eckardt score, worse dysphagia, regurgitation, or weight loss. In this increased cohort, this data once again suggests that longer symptom duration is not associated with increased rates of POEM failure.

Preoperative Symptom Duration and the Effect on Clinical Outcomes and PROMIS-PF in Patients Undergoing Lumbar Fusion Surgery.

Retrospective Review. The purpose of this study is to examine the effect of preoperative symptom duration on postoperative clinical outcomes for patients undergoing lumbar fusion surgery. Lumbar fusion surgery can be significantly beneficial for lumbar spondylolisthesis and spinal stenosis. Surgical treatment is typically preceded by some amount of non-operative intervention and there isn't a consensus on the optimal timing between symptom onset and surgical intervention. A retrospective review of 144 patients undergoing a 1-3 level lumbar fusion from June 2020 to December 2023 was performed. Demographics, preoperative symptom onset, primary diagnosis, and surgical procedure were compared between patients with less than or greater than 2 years of symptoms. Postoperative outcomes and PROMIS-PF were compared between groups. Univariate and multivariate analyses were performed. 52 (36.1%) had symptoms for 2 years or longer while 92 (63.9%) had symptoms for less than 2 years. There was no difference in demographics, procedure type, primary diagnosis, or preoperative symptoms between those who had symptoms for greater than or less than 2 years. Those who had symptoms for 2+ years had a significantly lower change in PF (4.7±7.1 vs. 7.7±9.0; P=0.029) and lower rate of MCID achievement (44.2% vs. 65.2%; P=0.023). There was no difference in outcomes by symptom duration. On multivariate analysis those with symptoms of 2 years or more were 2.4 times less likely to achieve an MCID (OR: 0.42, 95% CI: 0.19 to 0.92; P=0.031). Patients undergoing lumbar fusion with greater than 2 years of symptoms prior to surgery have a smaller increase in PROMIS-PF and are less likely to achieve MCID on PROMIS-PF. Further study is needed in order to determine the optimal timing for lumbar fusion surgery following symptom onset.

The impact of preoperative ureteral stent duration on retrograde intrarenal surgery results: a RIRSearch group study.

A JJ stent placed before retrograde intrarenal surgery (RIRS) may ease the procedure. However, it is important to note that a prolonged duration of double J stent (DJS) placement before RIRS may increase the risk of postoperative urinary tract infection (UTI). Various publications have established this association, although the duration of the DJS before surgery is scarce. Our study investigates the relationship between the pre-stenting period and postoperative UTI and establishes a cut-off period to minimize this risk. We included a total of 500 cases with preoperative DJS prior to RIRS. The patients were divided into five groups according to their preoperative stenting duration (Group 1: 0-15 days; Group 2: 16-30 days; Group 3: 31-45 days; Group 4: 46-60 days; Group 5: >60 days). Demographic and clinical data of the patients, stone properties, operation data, perioperative and postoperative complications (including fever and UTI), hospitalization time, and stone-free rates (SFR) were compared. The groups contained 53, 124, 102, 63, and 158 patients. The demographics of the patients in each group were similar. There was no statistically significant difference between DJS duration, perioperative/postoperative complications, and SFR, except for the ureteral access sheath (UAS) insertion rate. (p = 0.001). The postoperative fever/UTI rate was the lowest in Group 1 (p = 0.046) compared to other durations. Stent duration does not impact SFR. Longer stents enhance UAS insertion success but increase postoperative infection risk. Our results suggest that RIRS should be performed within two weeks, ideally 20 days following stent insertion, to minimize postoperative infection risk.

Prognostic Impact of a Decrease in Serum Carbohydrate Antigen 19-9 Levels After Preoperative Therapy for 4 Months or More for Borderline Resectable Pancreatic Cancer Abutting Major Arteries.

Background: This study aimed to identify the prognostic factors after pancreatectomy for borderline resectable pancreatic cancer abutting major arteries (BR-A).Methods: We retrospectively investigated relationship between preoperative and intraoperative variables and overall survival (OS) through univariate and multivariate analyses. The cut-off points of preoperative therapy duration and response rates of serum carbohydrate antigen 19-9 (CA19-9) levels after preoperative therapy were determined through a minimum P-value approach using the log-rank test for OS. Overall survival was compared among patients stratified according to the independent prognostic factors and the presence or absence of pancreatectomy.Results: After pretreatment, 17 patients underwent pancreatectomy and four patients continued chemotherapy without surgery. Multivariate analysis in 17 resected BR-A patients demonstrated decreased serum CA19-9 levels and preoperative therapy duration of ≥4 months were the independent prognostic factors [hazard ratio (HR) 0.01; P = 0.002, HR 0.13; P = 0.02]. Patients who underwent surgery with decreased serum CA19-9 levels after preoperative therapy of ≥4 months had a significantly better prognosis than those without one or both of independent prognostic factors and those who did not undergo surgery (median survival time: not estimated, 23.3 months, 10.5 months, and 10.8 months; P = 0.02, P = 0.004, and P = 0.001, respectively). Furthermore, the prognosis did not significantly differ between the patients who underwent surgery without meeting either one or both criteria and those without surgery.Conclusions: Preoperative therapy duration of ≥4 months and decreased serum CA19-9 levels are independent prognostic factors among BR-A patients.

Outcomes of patients with initially unresectable pancreatic cancer who underwent conversion surgery after FOLFIRINOX or gemcitabine plus nab-paclitaxel chemotherapy: A multicenter retrospective cohort study (PC-CURE-1).

The efficacy and safety of conversion surgery (CS) after FOLFIRINOX or gemcitabine plus nab-paclitaxel (GnP) chemotherapy in patients with initially unresectable pancreatic cancer (PC) remains unclear. This multicenter retrospective cohort study enrolled patients, between 2014 and 2018, with initially locally advanced or metastatic PC who were considered candidates for CS following FOLFIRINOX or GnP chemotherapy. They were classified into surgery (207 patients [194 resection and 13 exploratory laparotomy only]) and continued chemotherapy (10 patients, control) groups. The primary endpoint was overall survival (OS) from the day of diagnosis of potentially curative resection on imaging studies, with an expected hazard ratio (HR) of 0.7. OS in the surgery group was longer than that in the control group (HR, 0.47; 95% confidence interval [CI]: 0.24-0.93). The median OS was 34.4 (95% CI: 27.9-43.4) and 19.8 (95% CI: 14.9-31.1) months in the surgery and control groups, respectively. The Clavien-Dindo grade ≥ IIIa postoperative complication and in-hospital mortality rates were 19.6% and 0.5%, respectively. Multivariate analysis revealed that preoperative chemotherapy duration was not associated with OS. CS, following a favorable response to FOLFIRINOX or GnP chemotherapy, improved initially unresectable PC prognosis (specifically, OS), regardless of the chemotherapy duration.

Doctor shopping trend of patients before undergoing rotator cuff repair in Korea: a multicenter study.

This study aims to investigate the trend of doctor shopping among patients with rotator cuff tear (RCT) before undergoing surgery and to examine the relevance of these findings to the public. A survey was conducted of 326 patients from 10 hospitals (male, 176; female, 150) who underwent arthroscopic rotator cuff repair (ARCR) for symptomatic RCT between September 2019 and February 2020. A questionnaire was used to obtain data regarding the type of medical care service, medical institutions visited before surgery, number of treatments received, and cost of treatment. A total of 326 patients (87%) received treatment at least once at another medical institution before visiting the hospital where the surgery was performed. Patients visited an average of 9.4 health providers or physicians for shoulder pain before visiting the hospital where surgery was performed. Among the 326 patients, 148 (45%) visited more than two medical institutions and spent an average of 641,983 Korean won (KRW; $466, 50,000-5,000,000 KRW) before surgery. Medical expenses before surgery were proportional to the number of medical institutions visited (P=0.002), symptom duration (P=0.002), and initial visual analog scale (VAS) pain score (P=0.007) but were not associated with sex, age, VAS pain score immediately before surgery, or RCT size. Medical expense before ARCR was associated with the severity of preoperative pain and duration of symptoms. After onset of shoulder symptoms, patients should visit as soon as possible a hospital that has surgeons who specialize in shoulder repair to prevent unnecessary medical expense and proper treatment. Level of evidence: IV.

The Association of Preoperative Hip Pain Duration With Delayed Achievement of Clinically Significant Outcomes After Hip Arthroscopic Surgery for Femoroacetabular Impingement Syndrome

Background: Patients with hip pain ≥2 years before hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS) have been shown to achieve inferior short-term and midterm outcomes compared with patients with a shorter pain duration, although there is limited literature that has evaluated the time to achieve clinically significant outcomes (CSOs) in this population. Purpose: To compare the time to achieve CSOs after hip arthroscopic surgery for FAIS in patients with and without prolonged hip pain and to identify independent predictors of the delayed achievement of CSOs. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent primary hip arthroscopic surgery for FAIS between January 2012 and July 2019 with 6-month, 1-year, and 2-year Hip Outcome Score–Activities of Daily Living (HOS-ADL) and Hip Outcome Score–Sports Subscale (HOS-SS) scores were identified. Patients with prolonged hip pain (preoperative duration ≥2 years) were propensity score matched to a control group (preoperative duration <2 years), controlling for age, sex, and body mass index (BMI). The times to achieve the minimal clinically important difference and Patient Acceptable Symptom State were compared between groups using Kaplan-Meier survival analysis. Multivariate Cox regression considering age, sex, BMI, pain duration, activity level, and chondral status was used to identify independent predictors of the delayed achievement of CSOs. Results: A total of 179 patients with prolonged hip pain were matched to 179 control patients (mean pain duration, 60.5 ± 51.2 vs 9.7 ± 5.1 months, respectively; P < .001) of a similar age, sex, and BMI (P≥ .488) with similar baseline HOS-ADL and HOS-SS scores (P≥ .971). The prolonged hip pain group showed delayed achievement of the minimal clinically important difference and Patient Acceptable Symptom State for both the HOS-ADL and HOS-SS on Kaplan-Meier analysis (P≤ .020). On multivariate Cox regression, hip pain duration ≥2 years was shown to be an independent predictor of the delayed achievement of CSOs, with hazard ratios ranging from 1.32 to 1.65 (P≤ .029). Additional independent predictors of the delayed achievement of CSOs included increasing age, increasing BMI, female sex, self-endorsed weekly participation in physical activity, and high-grade chondral defects (hazard ratio range, 1.01-4.89; P≤ .045). Conclusion: Findings from this study demonstrate that preoperative hip pain duration ≥2 years was an independent predictor of the delayed achievement of CSOs after primary hip arthroscopic surgery for FAIS.
