RESUMO
BACKGROUND: Postinterventional sonographic assessment of the femoral artery after transfemoral transcatheter aortic valve replacement (TF-TAVR) has the potential to identify several pathologies. We investigated the incidence and risk factors of femoral vessel complications in a modern TAVR collective using postinterventional sonography. METHODS: Between September 2017 and March 2022, 480 patients underwent TF-TAVR with postinterventional femoral sonography at a single center. Clinical outcomes and adverse events were analyzed after the Valve Academic Research Consortium 3 (VARC-3) criteria. RESULTS: In this cohort (51.2% male; age 80 ± 7.5 years, median EuroSCORE II 3.7) 74.8% (n = 359) were implanted with a self-expandable and 25.2% (n = 121) with a balloon-expandable valve. The main access (valve-delivery) was located right in 91.4% (n = 438), and the primary closure system was Proglide in 95% (n = 456). Vascular complications (VC) were observed in 29.16% (n = 140) of patients; 23.3% (n = 112) presented with minor- and 5.8% (n = 28) with major VC. Postinterventional femoral artery stenosis on the main access was observed in 9.8% (n = 47). Multivariable logistic regression analysis revealed female sex (p = .03, odds ratio [OR] 2.32, 95% confidence interval [CI] 1.09-4.89) and the number of used endovascular closure devices (p = .014, OR 0.11, 95%CI 0.02-0.64) as predictive factors for femoral artery stenosis. CONCLUSIONS: The incidence of postinterventional femoral artery stenosis following TF-TAVR was higher than expected with a number of used closure devices and female sex being independent risk factors. Considering the continuous advance of TAVR in low-risk patients with preserved physical activity, emphasis should be directed at the correct diagnosis and follow-up of these complications.

INTRODUCTION: Many pouch complications following ileoanal pouch surgery have an inflammatory or mechanical nature, and specialist colorectal surgeons are required to assess the anatomy of the ileoanal pouch in multiple settings. In this study, we report our stepwise clinical and endoscopic assessment of the patient with an ileoanal pouch. METHODS: The most common configuration of the ileoanal pouch is a J-pouch, and the stapled anastomosis is more frequently performed than a handsewn post-mucosectomy. A structured clinical and endoscopic assessment of the ileoanal pouch must provide information on 7 critical areas: anus and perineum, rectal cuff, pouch anal anastomosis, pouch body, blind end of the pouch, pouch inlet and pre-pouch ileum. RESULTS: We have developed a structured pro forma for step-wise assessment of the ileoanal pouch, according to 7 essential areas to be evaluated, biopsied and reported. The structured assessment of the ileoanal pouch in 102 patients allowed reporting of abnormal findings in 63 (61.7%). Strictures were diagnosed in 27 patients (26.4%), 3 pouch inlet strictures, 21 pouch anal anastomosis strictures, and 3 pre-pouch ileum strictures. Chronic, recurrent pouchitis was diagnosed in 9 patients, whilst 1 patient had Crohn's disease of the pouch. CONCLUSIONS: Detailed clinical history, assessment of symptoms and multidisciplinary input are all essential for the care of patients with an ileoanal pouch. We present a comprehensive reporting pro forma for initial clinical assessment of the patient with an ileoanal pouch, with the aim to guide further investigations and inform multidisciplinary decision-making.

INTRODUCTION: For individuals with lumbar spinal stenosis (LSS), minimally invasive procedures such as an interspinous spacer device without decompression or fusion (ISD) or open surgery (i.e., open decompression or fusion) may relieve symptoms and improve functions when patients fail to respond to conservative therapies. This research compares longitudinal postoperative outcomes and rates of subsequent interventions between LSS patients treated with ISD and those with open decompression or fusion as their first surgical intervention. METHODS: This retrospective, comparative claims analysis identified patients age ≥ 50 years with LSS diagnosis and with a qualifying procedure during 2017-2021 in the Medicare database which includes healthcare encounters in inpatient and outpatient settings. Patients were followed from the qualifying procedure until end of data availability. The outcomes assessed during the follow-up included subsequent surgical interventions, including subsequent fusion and lumbar spine surgeries, long-term complications, and short-term life-threatening events. Additionally, the costs to Medicare during a 3-year follow-up were calculated. Cox proportional hazards, logistic regression, and generalized linear models were used to compare outcomes and costs, adjusted for baseline characteristics. RESULTS: A total of 400,685 patients who received a qualifying procedure were identified (mean age 71.5 years, 50.7% male). Compared to ISD patients, patients receiving open surgery (i.e., decompression and/or fusion) were more likely to have a subsequent fusion [hazard ratio (HR), 95% confidence intervals (CI): 1.49 (1.17, 1.89)-2.54 (2.00, 3.23)] or other lumbar spine surgery [HR (CI): 3.05 (2.18, 4.27)-5.72 (4.08, 8.02)]. Short-term life-threatening events [odds ratio (CI): 2.42 (2.03, 2.88)-6.36 (5.33, 7.57)] and long-term complications [HR (CI): 1:31 (1.13, 1.52)-2.38 (2.05, 2.75)] were more likely among the open surgery cohorts. Adjusted mean index costs were lowest for decompression alone (US$7001) and highest for fusion alone ($33,868). ISD patients had significantly lower 1-year complication-related costs than all surgery cohorts and lower 3-year all-cause costs than fusion cohorts. CONCLUSIONS: ISD resulted in lower risks of short- and long-term complications and lower long-term costs than open decompression and fusion surgeries as a first surgical intervention for LSS.

BACKGROUND: New therapies have revolutionized the treatment of Crohn's disease (CD), but in some countries, the surgery rate has not changed, the frequency of emergency surgery is underestimated, and surgical risk is poorly studied. AIMS: The aim of this study was to identify risk factors and clinical indications for primary surgery in CD patients at the tertiary hospital. METHODS: This was a retrospective cohort of a prospectively collected database of 107 patients with CD from 2015 to 2021. The main outcomes were the incidence of surgery treatment, types of procedures performed, surgical recurrence, surgery free time, and risk factors for surgery. RESULTS: Surgical intervention was performed in 54.2% of the patients, and most of the procedures were emergency surgeries (68.9%). The elective procedures (31.1%) were performed over 11 years after diagnosis. The main indications for surgery were ileal stricture (34.5%) and anorectal fistulas (20.7%). The most frequent procedure was enterectomy (24.1%). Recurrence surgery was most common in emergency procedures (OR 2.1; 95%CI 1.6-6.6). Montreal phenotype L1 stricture behavior (RR 1.3; 95%CI 1.0-1.8, p=0.04) and perianal disease (RR 1.43; 95%CI 1.2-1.7) increased the risk of emergency surgeries. The multiple linear regression showed age at diagnosis as a risk factor for surgery (p=0.004). The study of surgery free time showed no difference in the Kaplan-Meier curve for Montreal classification (p=0.73). CONCLUSIONS: The risk factors for operative intervention were strictures in ileal and jejunal diseases, age at diagnosis, perianal disease, and emergency indications.

OBJECTIVE: Examine differences in cost between single stage (ss) versus double stage (ds) laryngotracheal reconstruction (LTR) for pediatric subglottic stenosis. STUDY DESIGN: Retrospective chart review of children who underwent ssLTR or dsLTR from 2014 to 2018 at a single institution. METHODS: Costs related to LTR and post-operative care up to one year after tracheostomy decannulation were extrapolated from charges billed to the patient. Charges were obtained from the hospital finance department and the local medical supplies company. Patient demographics including baseline severity of subglottic stenosis and co-morbidities were noted. Variables assessed include duration of hospital admission, number of ancillary procedures, duration of sedation wean, cost of tracheostomy maintenance, and time to tracheostomy decannulation. RESULTS: Fifteen children underwent LTR for subglottic stenosis. D Ten patients underwent ssLTR, while five underwent dsLTR. Grade 3 subglottic stenosis was more prevalent in patients who underwent dsLTR (100%) than ssLTR (50%). The average per-patient hospital charges for ssLTR was $314,383 versus $183,638 for dsLTR. When estimated mean cost of tracheostomy supplies and nursing care until tracheostomy decannulation was included, the mean total charges associated with dsLTR patients was $269,456. Average hospital stay after initial surgery was 22 days for ssLTR versus 6 days for dsLTR. Average time to tracheostomy decannulation for dsLTR was 297 days. Average number of ancillary procedures needed was 3 versus 8 for ssLTR versus dsLTR. CONCLUSION: For pediatric patients with subglottic stenosis, dsLTR may have a lower cost than ssLTR. Although ssLTR has the benefit of immediate decannulation, it is associated with higher patient charges, as well as longer initial hospitalization and sedation. For both patient groups, fees associated with nursing care comprised the majority of charges. Recognizing the factors that contribute to cost differences between ssLTR and dsLTR may be useful when performing cost-benefit analyses and assessing value in health care delivery.

OBJECTIVE: To report the effect of surgeon and facility volume on outcomes of transurethral resection of the prostate (TURP) and laser treatment of benign prostatic hyperplasia (BPH). We also investigate disparities in access to care by identifying demographic predictors of receipt of treatment at high-volume facilities. METHODS: We used New York State Department of Health Statewide Planning and Research Cooperative System (SPARCS) data. We included 18,041 (41.4%) and 25,577 (58.6%) adult patients that underwent TURP and laser procedures in the outpatient setting between January 2005 and December 2018, respectively. Average annual surgeon and facility volumes were broken down by tertile. The effect of volume on short-term outcomes (30-day and 90-day readmission) was examined using mixed-effect logistic regression models. Cox-proportional-hazard models were used to assess the association between volume and long-term stricture development and reoperation. Demographic predictors of treatment at high-volume facilities were assessed using multinomial logistic regression. RESULTS: High-volume facilities were more likely to offer laser procedures compared to low-volume facilities. Higher facility and surgeon volume were associated with lower odds of 30 and 90-day readmissions compared to low-volume facilities. There was no difference in reoperation and stricture development between surgeon volume groups. Medicaid insurance, Hispanic ethnicity, and Black race were inversely associated with treatment at high-volume facilities. CONCLUSION: Higher surgeon and facility volumes were associated with lower odds of readmission. Higher facility volume was associated with lower hazards of reoperation and developing strictures. Medicaid insurance and non-white race were associated with lower odds of treatment at high-volume facilities, highlighting racial and socioeconomic disparities in access to high-volume BPH surgery facilities.

Benign biliary strictures (BBS) develop in up to 10% to 30% of patients with chronic pancreatitis (CP).1 Endoscopic endoprosthetics via endoscopic retrograde cholangiopancreatography (ERCP) has become the standard of care for remediating these strictures. Seventy percent to eighty percent of these strictures resolve with sequential or concurrent placement of multiple plastic stents (MPS).1,2 More recently, placement of fully covered self-expanding metal stents (FCSEMS) have been shown to have similar outcomes as MPS.3-6 FCSEMS provide a larger radial diameter and require fewer procedures, but may have drawbacks, including a higher risk of migration, cholecystitis, delamination, and tissue ingrowth. A recent study demonstrated that FCSEMS with a 12-month indwell had similar outcomes to MPS with fewer ERCP needed.7 However, the cost-effectiveness of either strategy for managing BBS has not been assessed previously nor has the impact of additional reimbursement to cover the cost of FCSEMS on the cost-effectiveness of FCSEMS utilization.

OBJECTIVE: To assess the incidence of genital pain in patients with urethral stricture and examine the impact of urethroplasty. Genital pain is a common and challenging urological condition and potentially associated with urethral stricture. METHODS: From 2011-2019, patients were offered enrollment in a prospective single-center study assessing patient-reported genital pain pre- and 6-months posturethroplasty. Genital pain was assessed with the question, "Do you experience genital (scrotum or penis) pain?" answered on a five-point scale ["Never" (1), "Occasionally" (2), "Sometimes" (3), "Most of the Time" (4) or "All of the Time" (5)]. Responses of 3, 4, or 5 were considered clinically significant. Wilcoxon signed-rank test was used to compare pre- and postoperative states and logistic regression was used to evaluate the association between genital pain and clinical variables. RESULTS: Of the 387 patients completing enrollment, 36.4% (141/387) reported genital pain preoperatively. Patients with panurethral stricture reported higher rates (57.1%) of pain (Odds Ratio 2.93, 95%CI 1.32-6.50; P = .008). Posturethroplasty, pain scores improved with an incidence of 14.2% (P < .0001). In patients reporting preoperative pain, 88.7% (125/141) experienced improvement, 8.5% were unchanged and 2.8% reported worsening pain. On logistic regression, patients with penile strictures (O.R. 0.24, 95%CI 0.06-0.91; P = .04), hypospadias (O.R. 0.14, 95%CI 0.02-0.88; P = .04), and staged reconstruction (O.R. 0.22, 95%CI 0.05-0.90; P = .04) were less likely to report improvement. CONCLUSION: Genital pain is common in patients with urethral stricture and improves in the majority of patients undergoing urethroplasty but less so in patients with penile strictures, hypospadias and staged reconstruction.

INTRODUCTION: To evaluate the prevalence, predictors, management, and trends for ureteroenteric strictures (UES) after robot-assisted radical cystectomy (RARC). METHODS: Retrospective review of our RARC database was performed (2005-2022). UES was described in terms of timing, laterality, and management. Kaplan-Meier curves were used to depict time to UES. Local regression was used to assess trend of UES over time and multivariable regression to identify variables associated with UES. RESULTS: UES occurred in 109 patients (15%). UES occurred in 13%, 17%, and 19% at 1, 3, and 5 years after RARC, respectively. Incidence of UES decreased in 2017, coinciding with stentless uretero-enteric anastomosis. UES occurred on the right in 33%, on the left in 46%, and bilaterally in 21%. All patients were initially managed by nephrostomy/stent. Surgical revision was required in 45% of patients, of which 13% developed recurrent UES after revision. On MVA, UES formation was associated with ureteral stents (OR 2.27, 95%CI 1.01-5.10, P = .05) and receipt of neoadjuvant chemotherapy (OR 2.01, 95%CI 1.24-3.25, P = .005). CONCLUSION: UES occurred in 15% of patients after RARC, with 45% of patients requiring surgical reimplantation. Ureteral stents and the receipt of neoadjuvant chemotherapy were associated with UES formation.

PURPOSE: Bile duct injuries (BDIs) are the potential grievous complications of cholecystectomy that result in substantial morbidity and mortality. Outcomes of BDI management depend on multiple factors such as the type and extent of injury, timing of repair, and surgical expertise. The present retrospective study was conducted to analyse the risk factors associated with the BDI repair outcomes. METHODS: The data of patients having primary or recurrent bile duct stricture following BDI from 1985 to 2018 were retrospectively evaluated. RESULTS: A total of 268 patients underwent hepaticojejunostomy (HJ). Of the total, 218 patients had primary bile duct stricture, and 50 patients had HJ stricture. The most commonly performed procedure for primary BDI was Roux-en-Y HJ (RYHJ), followed by right hepatectomy, right posterior sectionectomy, and left hepatectomy. All patients with strictured HJ underwent RYHJ, except one who underwent a right hepatectomy. Outcome assessment using the McDonald grading system showed that 62%, 27%, 5%, and 6% of patients with primary bile duct stricture had grade A, grade B, grade C, and grade D complications, respectively, with a mortality rate of 3.21%, whereas 46%, 34%, and 18% patients with strictured HJ had grade A, grade B, and grade C complications, respectively, with a mortality rate of 2%. High-up biliary strictures, early repair, and blood loss > 350 mL are the surrogate markers for failure of repair. CONCLUSION: Management of BDI needs a multidisciplinary approach. The outcomes of both primary biliary stricture and strictured HJ can be improved with management of patients in a tertiary care centre. However, attempts to repair within 2 weeks of injury, Strasberg E4 and E5, and blood loss of > 350 mL may have an adverse effect on the outcome of HJ.

PURPOSE: The severity of congenital tracheal stenosis (CTS) is commonly evaluated based on the degree of stenosis. However, it does not always reflect the clinical respiratory status. We applied computational fluid dynamics (CFD) to the assessment of CTS. The aim of this study was to evaluate its validity. METHODS: CFD models were constructed on 15 patients (12 preoperative models and 15 postoperative models) with CTS before and after surgery, using the computed tomographic data. Energy flux, needed to drive airflow, measured by CFD and the minimum cross-sectional area of the trachea (MCAT) were quantified and evaluated retrospectively. RESULTS: The energy flux correlated positively with the clinical respiratory status before and after surgery (rs = 0.611, p = 0.035 and rs = 0.591, p = 0.020, respectively). Although MCAT correlated negatively with the clinical respiratory status before surgery (rs = -0.578, p = 0.044), there was not significant correlation between the two after surgery (p = 0.572). CONCLUSIONS: The energy flux measured by CFD assessment reflects the respiratory status in CTS before and after surgery. CFD can be an additional objective and quantitative evaluation tool for CTS.

ABSTRACT: Percutaneous drainage catheters (PDCs) are required for the management of benign biliary strictures refractory to first-line endoscopic treatment. While biliary patency after PDC placement exceeds 75%, long-term catheterization is occasionally necessary. In this article, we assess the outcomes of patients at our institution who required long-term PDC placement.A single-institution retrospective analysis was performed on patients who required a PDC for 10âyears or longer for the management of a benign biliary stricture. The primary outcome was uncomplicated drain management without infection or complication. Drain replacement was performed every 4 to 12âweeks as an outpatient procedure.Nine patients (three males and six females; age range of 48-96âyears) required a long-term PDC; eight patients required the long-term PDC for an anastomotic stricture and one for iatrogenic bile duct stenosis. A long-term PDC was required for residual stenosis or patient refusal. Drain placement ranged from 157 to 408âmonths. In seven patients, intrahepatic stones developed, while in one patient each, intrahepatic cholangiocarcinoma or hepatocellular carcinoma occurred.Long-term PDC has a high rate of complications; therefore, to avoid the need for using long-term placement, careful observation or early surgical interventions are required.

BACKGROUND: Endoscopic balloon dilation (EBD) has emerged as an alternative intervention to manage Crohn's disease (CD) strictures. We determined the cost-effectiveness of EBD versus resection surgery for patients with short (< 4-5 cm) primary or secondary/anastomotic small or large bowel strictures. METHODS: A microsimulation state-transition model analyzed the benefits and risks of EBD and resection surgery for patients with primary or anastomotic CD strictures. Our primary outcome was quality-adjusted life years (QALYs) over ten years, and strategies were compared using a willingness to pay of $100,000/QALY from a societal perspective. Costs (2021 $US) and incremental cost-effectiveness ratios (ICER) were calculated. Deterministic 1-way and probabilistic analyses assessed model uncertainty. RESULTS: The EBD strategy cost $19,822 and resulted in 6.18 QALYs while the surgery strategy cost $41,358 and resulted in 6.37 QALYs. Surgery had an ICER of $113,332 per QALY, making EBD a cost-effective strategy. The median number of EBDs was 5 in the EBD strategy and 0 in the surgery strategy. The median number of surgeries was 2 in the surgery strategy and 1 in the EBD strategy. Of individuals who initially received EBD, 50.4% underwent subsequent surgery. One-way sensitivity analyses showed that the probabilities of requiring repeated interventions, surgery mortality (< 0.7%), and quality of life after interventions were the most influential model parameters. Probabilistic sensitivity analyses favored EBD in 50.9% of iterations. CONCLUSIONS: EBD is a cost-effective strategy for managing CD strictures. Differences in patient risk and quality of life after intervention impact cost-effectiveness. Intervention decisions should consider cost-effectiveness, patient risks, and quality of life.

BACKGROUND: Ultrasound is a reliable tool for airway assessment and management. We evaluated the accuracy of ultrasound in the preprocedure planning and follow-up evaluation of patients undergoing airway stenting for benign upper airway stenosis. METHODS: This was a retrospective single center study on patients with benign upper airway stenosis treated with airway stenting. Ultrasound evaluated the characteristics of the stenosis (distance from vocal folds, diameter, and length) before treatment and any complications after treatment; these results were then statistically compared with those obtained by computed tomography, taking the endoscopy as the reference method. RESULTS: Twenty-seven patients were evaluated. Ultrasound was significantly correlated with endoscopy and computed tomography scan measurements as distance of stenosis from vocal folds (r = 0.88; P < .001 and r = 0.87; P < .001, respectively), diameter of the stenosis (r = 0.97; P < .001 and r = 0.97; P < .001, respectively), and length of the stenosis (r = 0.97; P < .001 and r = 0.97; P < .001, respectively). Four out of 27 (15%) patients presented complications after treatment as stent migration (n = 2; 7%); stent obstruction (n = 1; 4%), and granulation of vocal fold (n = 1; 4%). All complications but granulation of vocal fold were correctly depicted by ultrasound and computed tomography without significant difference in comparison to endoscopy (P = .87) CONCLUSIONS: Ultrasound is a promising tool in assessment of airway stenosis and follow-up of patients after stenting; it may be routinely used in adjunction to computed tomography and/or endoscopy in this setting, if our results are corroborated by a future larger study.

OBJECTIVE: To assess the tracheal elasticity and tracheal anastomosis tension for prevention of anastomosis-related complications and estimation of the maximum length of resection. MATERIAL AND METHODS: At the first stage, 20 patients with cicatricial tracheal stenosis underwent tracheoscopy in usual position, under maximum flexion and extension of the head for the period from September 2017 to December 2019. We measured the total length of trachea and length of stenotic segment. Tracheal extensibility was assessed considering the difference in measurements. At the second stage, anastomosis tension was intraoperatively measured using a dynamometer in normal head position, as well as at maximum flexion in 22 patients who underwent tracheal resection. Unlike multiple other studies, we studied tissue tension intraoperatively. RESULTS: Mean length of trachea was 12.8 cm, extensibility - 1.3 cm. Tracheal elasticity was greater in patients with a longer trachea and in patients under 40 years old. Mean length of resection was 3.9 cm (30% of mean length of trachea), anastomosis tension - 2.7 H or 270 g. Head flexion was followed by tension decrease by 0.7 H (26.9%), i.e. 70 g. This approach is less effective in case of resection of more than 30% of trachea length in a particular patient. CONCLUSION: Further experience in measurement of tracheal extensibility and anastomosis tension will make it possible to establish clinical significance of these indicators for prevention of complications.

STUDY DESIGN: A retrospective study. OBJECTIVE: The aim of this study was to explore the relationship between postoperative neurological disturbance of the upper extremities (NDUE) after cervical laminoplasty and intervertebral foraminal stenosis. SUMMARY OF BACKGROUND DATA: The relationship between foraminal stenosis and neurological disturbance in the C5 segment (C5 palsy) has been reported, but the relationship at other levels has not been examined before. We evaluated foraminal stenosis morphologically using three-dimensional computed tomography (3D-CT), alongside other risk factors for NDUE. METHODS: We retrospectively reviewed patients treated by open-door laminoplasty at the authors' institution between January and June 2016. NDUE was defined as postoperative motor deterioration and/or newly emerged sensory disturbance within 2 weeks of surgery. Radiological measurements were performed in bilateral intervertebral foramina from C5 to C8, using 3D-CT. Investigation using magnetic resonance imaging (MRI) was also performed. RESULTS: Thirty-one patients were reviewed, and 10 (32.3%) developed NDUE. Nineteen NDUE were observed: seven were in the C5 segment, five in the C6 segment, three in the C7 segment, and four in the C8 segment. Four patients (40%) had NDUE from multiple segments. The mean width of the foramen was 2.60â±â1.26âmm and 3.66â±â1.66âmm (Pâ=â0.007), and cross-sectional area was 32.8â±â10.8âmm and 41.6â±â12.4âmm (Pâ=â0.003), in symptomatic (nâ=â19) and nonsymptomatic (nâ=â187) foramina, respectively. The mean transverse diameter of bony spurs and the maximum shift of the spinal cord on MRI was significantly larger in the NDUE group. The odds ratio of having a foraminal cross-sectional area under 28.0 mm in combination with a maximum spinal shift over 3.10âmm was 14.6 (Pâ<â0.001). CONCLUSION: Stenosis of the intervertebral foramen could be a risk factor for NDUE after cervical laminoplasty, and could be aggravated by excessive posterior spinal cord shift. LEVEL OF EVIDENCE: 3.

BACKGROUND: Anastomotic bile duct stricture (ABS) is one of the most common complications after liver transplantation. Current practice of endoscopic retrograde cholangiopancreatography (ERCP) with multiple plastic stent (MPS) insertion often requires multiple sessions before achieving stricture resolution. We aimed to compare the efficacy of fully covered self-expandable metallic stent (FCSEMS) with MPS method while simultaneously analyzing the relative healthcare cost between the two methods in the management of ABS. METHODS: Liver transplant patients with ABS who received ERCP with stent placement were identified by query of our endoscopic database. Comparative analyses between the group of patients treated with ERCP with MPS and the group treated with FCSEMS were performed. The costs to achieve stricture resolution, and the rates of stricture resolution, recurrence and complications were also compared. RESULTS: A total of 158 patients underwent ERCP with stent insertion for the management of ABS. Of those, 49 patient received FCSEMS for their ABS while 109 patients were treated with MPS only. Our cost analysis showed early utilization of FCSEMS can deliver up to 25% savings in the total procedure cost while providing comparable rates of stricture resolution. The rates of technical success, stricture recurrence and adverse outcomes, and stricture free durations were also comparable between the two groups. CONCLUSION: While providing efficacy and safety rates comparable to ERCP-MPS, the incorporation of FCSEMS at early stage of ABS management could provide a substantial savings by reducing the number of ERCP session to achieve stricture resolution. Optimization of the timing and duration of FCSEMS indwelling time needs further validation.

INTRODUCTION: Acquired skin-level strictures following posterior sagittal anorectoplasty (PSARP) and some rare cases of congenital anal stenosis can be managed using a Heineke-Mikulicz like anoplasty (HMA). We hypothesized that this procedure was an effective, safe, and durable outpatient procedure in select patients. METHODS: We retrospectively reviewed all patients who underwent HMA for skin level strictures following PSARP or for certain congenital anal stenoses from 2014 to 2017. RESULTS: Twenty-eight patients (19 males, 9 females) with a mean age of 5.8â¯years (range 0.5-24.4) underwent HMA. Twenty-six had a prior PSARP, of which 18 were redo, and 8 were primary procedures. Two patients had congenital skin level anal stenosis. The mean follow up was 1.0â¯years (range 0.4-2.9). The average preprocedure anal size was Hegar 8, which after HMA increased 8 Hegar sizes to 16 (95% CI 7-9, pâ¯<â¯0.001). There were no operative complications. One patient restenosed and required a secondary procedure. CONCLUSION: HMA is a safe procedure for skin-level anal strictures following PSARP (primary and redo) and can also be used in some rare cases of congenital anal stenosis. Long-term follow up to determine the restricture rate is ongoing. A plan to do an HMA if a stricture develops may offer an alternative to routine anal dilations, particularly after a redo PSARP in an older child. TYPE OF STUDY: Case series. LEVEL OF EVIDENCE: Level IV.

Tracheal flow in infants with congenital tracheal stenosis (CTS) was numerically investigated using subject-specific airway models before and after reconstructive surgery. We quantified tracheal flow based on airway resistance during inhalation, and compared it between controls and patients before and after surgery. The airway resistance in each subject was assessed using geometrical parameters of the trachea: the minimum cross-sectional area Amin, the minimum cross-sectional area normalized by the standard deviation of the cross-sectional area Amin/σA, the area ratio of the minimum and maximum cross-sectional area Amin/Amax, and ratio of the normalized standard deviation of cross-sectional area to the mean cross-sectional area σA/Amean. Our numerical results demonstrated that such geometrical parameters could be used to assess the severity of CTS. Since subjects can be more clearly categorized as controls and most preoperative patients in terms of the airway resistance, a simulation using subject-specific airway models can lead us to a precise understanding of tracheal flow, and also provide knowledge about therapeutic decision. Our numerical results also demonstrated that significant surgical expansion of cross-sectional area did not help recover tracheal flow because of expansion loss. These results will be helpful not only when making therapeutic decisions about surgery but also when assessing quality of life in postoperative patients. Graphical abstract.
