Repeated Endoscopic Dilation and Needle Knife Stricturotomy for Crohn's Disease Strictures.

BACKGROUND AND AIMS: Crohn's disease strictures are usually treated by a single endoscopic balloon dilation (EBD). We postulated repeat EBD and needle-knife stricturotomy (NKSt), together with inflammation controlled by intense drug therapy, may be more effective. METHODS: 21 patients with symptomatic strictures were randomised to single EBD or intensive treatment with 3 balloon dilations 3 weeks apart and/or NKSt RESULTS: Of 21 patients 2 of 5 (40%) five with a single EBD and 12/16 [72%] with intensive treatment had symptom improvement (OR 4.49 [95% CI 0.54 - 37.4]; P = 0.164). Eleven patients received >1 EBD without NKSt, 5 had ≥1 NKSt. NKSt treated patients and those with concurrent intensified drug treatment had the best outcomes. CONCLUSIONS: Crohn's disease stricture treatment with repeat dilations or stricturotomy is feasible, safe and may improve stricture outcomes. Concurrent intensified drug treatment to eliminate inflammation is also associated with improved outcome.

Combining biopsy needle and virtual bronchoscopy for tuberculosis-induced complete bronchial blockage.

Endobronchial tuberculosis (EBTB) presents significant clinical challenges, particularly when complete bronchial obstruction occurs. In this case, a young woman with right main bronchus occlusion due to tuberculosis (TB) was treated using a novel approach. Instead of using a traditional rigid bronchoscope, a flexible approach was adopted. Under precise fluoroscopic guidance, a 21-gauge transbronchial aspiration needle was used to puncture the obstruction, allowing passage of the guidewire and subsequent balloon dilation. The use of virtual bronchoscopy, developed using computed tomography scans, ensures safe navigation around critical vascular structures. Postoperatively, the patient showed significant symptomatic improvement without complications. This innovative approach not only demonstrates the efficacy and safety of using biopsy needles and virtual bronchoscopy for managing complete bronchial obstructions in EBTB but also opens the door for future innovative solutions in such complex cases.

Endoscopic Management of Lower Gastrointestinal Tract Anastomosis Strictures: A Meta-Analysis and Systematic Review of the Literature.

BACKGROUND: Anastomotic strictures following colectomy and proctectomy are a significant cause of benign lower gastrointestinal tract (LGIT) obstruction, with a reported incidence of up to 30%. Endoscopic interventions such as balloon dilation, stricturotomy, mechanical dilation, electrocautery incision, and stent placement are utilized for management. This meta-analysis aimed to evaluate the efficacy and safety of endoscopic interventions for the management of benign LGIT anastomotic strictures. METHODS: Literature search was performed for published full-text articles using the Embase, Pubmed, Web of Sciences, and Cochrane databases for endoscopic management of anastomosis strictures and related terms including endoscopic balloon dilation (EBD), stricturotomy (EST), mechanical dilation, electrocautery incision (ECI), and stent placement. RESULTS: A total of 1363 patients from 33 studies were included. The most common indication for anastomosis was colorectal cancer (92%). Overall technical success (ability to pass the endoscope) was achieved in 93% of cases, with immediate clinical success in 85% and sustained success in 81% at follow-up. ECI demonstrated the highest clinical success rates (98% immediate, 91% at the end of follow-up). Adverse events occurred in 6% of patients, most commonly perforation, which was most frequent with EBD. Stent placement showed high initial success but had issues with stent migration and adverse events. CONCLUSION: Overall, EBD and ECI were the most effective, with ECI showing the highest success rates. Despite its technical challenges, EST was both effective and safe. This study underscores the need for further prospective research comparing various endoscopic interventions to improve management strategies for LGIT anastomotic strictures.

Retrograde Ejaculation Due to Posterior Urethral Stricture: A Rare Case Report.

Pelvic fracture is a serious injury, which has a profound impact on sexual function due to concurrent nervous and urethral injuries. In this case report, we describe a 29-year-old single man who had retrograde ejaculation as a result of a pelvic fracture-related posterior urethral stricture. The patient wanted to improve his ejaculatory ability after experiencing urethral stricture for 8 years and retrograde ejaculation for 3 years following the pelvic fracture. We precisely located and measured the patient's urethral stricture using a retrograde urethrogram, and we used transrectal color Doppler ultrasound to track the patient's ejaculation process in real time. Next, we used urethral balloon dilatation to relieve the urethral stricture. Urinary obstruction symptoms have completely resolved, and the patient was able to urinate without any obstructions. Meanwhile, the real-time transrectal color Doppler ultrasound result showed that some semen might ejaculate externally by passing through the initial stricture area, while some semen continued to flow retrogradely into the bladder.

Congenital Pyriform Aperture Stenosis: Not All Patients Require Open Repair.

OBJECTIVE: Evaluate the management options for congenital nasal pyriform aperture stenosis (CNPAS). STUDY DESIGN: Case series. SETTING: Tertiary referral children's hospital. METHODS: The medical records of CNPAS patients managed from January 2015 to 2023 were reviewed for medical history, management, and outcomes. RESULTS: Fifteen patients met inclusion criteria. Six patients (40.0%) had a central mega incisor and 4 (26.7%) had holoprosencephaly. Three (20%) patients were managed with medications alone. Mean PA width was similar between patients managed medically versus those managed surgically (mean width 6.2 ± 0.15 mm vs 6.1 ± 0.38 mm). Median age at first procedure was 50 (range 8-263) days. Seven (46.7%) underwent an initial balloon nasal dilation and 5 (33.3%) underwent an open sublabial repair. Operative time was lower in the balloon dilation group (mean 27 vs 104 minutes). Five patients had a single balloon dilation and 2 required revision procedures: 1 underwent a second balloon dilation, and 1 patient underwent a subsequent open sublabial procedure. Four patients with an initial open sublabial approach returned to the operating room for nasal balloon dilation or debridement due to nasal synechiae. CONCLUSION: There has been general shift towards minimally invasive surgery. In our series, 8 (53.3%) patients were managed successfully with medical therapy or a single nasal balloon dilation procedure. Of those who underwent an open surgical repair, most (4/5) required a revision procedure due to synechiae. Given the relative success and lower operative time of balloon dilation, this option should be considered in the management algorithm for CNPAS.

In-office Eustachian Tube Dilation Reduces Symptoms Among Patients With Barometric Challenges.

INTRODUCTION: Balloon dilation of the eustachian tube has gained ground in the treatment of chronic dysfunction. A new indication for a larger group of patients has emerged, which is characterized by barochallenge only, which affects even more patients. Given the recent validation of the balloon dilation, we set out to explore if this procedure could be useful in treating this specific sub-group of patients in an in-office setting. METHODS: Balloon dilation was performed using inly nasal cottonoids soaked in 2% tretracainephenylephrine combined with xylocaine nasal spray and lidocaine/prilocaine gel and a mild oral sedative. The effect of eustachian tube balloon dilation on the function of the eustachian tube was evaluated by using the eustachian tube dysfunction questionnaire-7 (ETDQ-7) and a VAS score. The questionnaires were completed beforehand and 3 months and 12 months postoperatively to determine subjective surgical success. RESULTS: Two hundred and forty-six balloon dilation were performed in 132 participants. The results from the ETDQ-7 questionnaire and VAS scores showed a significant improvement in symptoms during pressurization after eustachian tube balloon dilation (p = 0.0001). A mean pain score during procedure in local anesthesia was 3.4 on a scale from 1 to 10. CONCLUSION: Eustachian tube balloon dilation significantly reduced symptoms of eustachian tube dysfunction during non-physiological pressure, which was determined by ETDQ-7 and Vas scores. Additionally, we found that the procedure is well suited for private practice or the outpatient clinic, using local anesthetics and a mild sedative. LEVEL OF EVIDENCE: 4 Laryngoscope, 2024.

Endoscopic Management of Strictures in Crohn's Disease: An Unsolved Case.

Crohn's disease (CD) is a chronic inflammatory disease associated with a significant burden in terms of quality of life and health care costs. It is frequently associated with several complications, including the development of intestinal strictures. Stricturing CD requires a careful multidisciplinary approach involving medical therapy and surgery, still posing a continuous management challenge; in this context, endoscopic treatment represents a valuable, in-between opportunity as a minimally invasive strategy endorsed by extensive yet heterogeneous evidence and evolving research and techniques. This review summarizes current knowledge on the role of therapeutic endoscopy in stricturing CD, focusing on evidence gaps, recent updates, and novel techniques intended for optimizing efficacy, safety, and tailoring of this approach in the view of precision endoscopy.

The long-term efficacy and safety of balloon dilation eustachian tuboplasty combined with tympanostomy tube insertion for patients with otitis media with effusion: study protocol for a prospective randomized controlled trial.

BACKGROUND: Otitis media with effusion (OME) is a common disease in ear, nose, and throat clinics characterized by aural fullness and hearing loss and mainly caused by eustachian tube dysfunction (ETD). Tympanostomy tube insertion (TTI) is a conventional surgical treatment option that can alleviate symptoms but does not provide a definitive cure, and it is prone to recurrence. Balloon dilation eustachian tuboplasty (BDET) has become a novel procedure for the treatment of ETD, demonstrating significant potential in addressing the aforementioned limitations. However, it is not widely available in the clinic and few high-quality randomized clinical trials was conducted to investigate its long-term efficacy and security in OME. Therefore, the purpose of this study is to verify the efficacy of BDET combined with TTI for patients with OME and its prospects for providing a definitive cure. METHODS AND ANALYSIS: This is a prospective, parallel-group, single-blind, randomized controlled prospective trial. Totally 124 patients with OME will be randomized into either group A or B. Group A will receive conventional therapy (TTI) while group B will use BDET therapy in addition to TTI. Outcome assessments will take place at baseline and at the 3rd, 6th, 12th, and 24th months after surgery. The primary outcome is eustachian tube function, which will be measured by the eustachian tube dysfunction questionnaire (ETDQ-7) and eustachian tube score (ETS). The secondary outcomes include middle ear function, hearing situation, and quality of life, which will be measured by acoustic impedance measurement, pure-tone audiometry, and Chinese-version Chronic Ear Survey (CCES). The main analysis of change in the outcomes will use mixed-model with repeated measures (MMRM) analyses of variance (ANOVAs). DISCUSSION: This is the first prospective trial in Chinese populations that aims to validate the long-term efficacy and safety of BDET-combined TTI therapy in patients with OME. This parallel-group, single-blind, randomized controlled trial may provide an opportunity to decrease the recurrence rate of OME and explore a definitive cure for patients with OME. This trial's rigorous design enhances the reliability of the findings, ensuring a robust answer to the research question. In the future, the research team will further expand upon the clinical evidence and applications of the BDET combined therapy. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2400079632.

Long-term outcomes of urethral balloon dilation for anterior urethral stricture: A prospective cohort study.

Objective: To prospectively follow up a cohort of anterior urethral stricture disease patients managed with balloon dilation (BD) for 3 years to evaluate the long-term outcomes and to study factors that contribute to recurrence. Methods: This study included men who had urethral BD for significant anterior urethral stricture disease between January 2017 and March 2019. Data about the patient age, stricture characteristics, and recurrence date were recorded, along with information on postoperative indwelling catheter use and operative complications. Furthermore, information about the self-calibration procedure was collected and where available, free flow (FF) measurements during the follow-up period were recorded and analyzed. Success was defined as a lack of symptoms and acceptable FF rates (maximum flow rate>12 mL/s). Results: The final analysis was conducted on 187 patients. The mean follow-up period was 37 months. The long-term overall success rate at the end of our study was 66.8%. Our recurrence rate was 7.4% at 12 months, 24.7% at 24 months, and reached 33.2% at the end of our study. The time to recurrence ranged from 91 days to 1635 days, with a mean of 670 days. The stricture-free survival was significantly shorter with lengthy peno-bulbar (p=0.031) and multiple strictures (p=0.015), and in the group of patients who were not committed to self-calibration protocol (p<0.011). However, post-procedural self-calibration was the most important factor that may have decreased the incidence of recurrence (odds ratio=5.85). Adjuvant self-calibration after BD not only reduced the recurrence rate from 85.4% in the non-self-calibration group to 15.1% in the self-calibration one (p<0.001), but also improved the overall stricture-free survival and FF parameters. Conclusion: Urethral BD has a high recurrence rate in the long-term, especially with long and multiple strictures. Adjuvant self-calibration has proven to reduce the recurrence risk and the need for re-intervention.

Endourological Treatment of Hydrocalycosis in a Patient With Kidney Transplantation.

Hydrocalyx is the obstruction of a renal calyx resulting from infundibulopelvic stenosis or diminution and can be congenital or acquired. A 37-year-old man with a history of preemptive kidney transplantation in 2007 and transplant rejection underwent another ABO-incompatible transplant. During follow-up four months after transplantation, a transplant biopsy was performed, which revealed acute thrombotic microangiopathy. Seven months after transplantation, the patient was admitted to the hospital because of elevated creatinine levels and dilatation of the upper calyx on ultrasound examination. Upper calyx hydrocalycosis and calyceal neck stenosis were diagnosed. Nephrostomy placement along with an antegrade double-J stent through the upper major calyceal neck was performed. Endoscopic dilatation of the narrowed neck of the upper major calyx 10 days after hydrocalyx decompression was performed without intraoperative or postoperative complications. During follow-up, the patient was asymptomatic, had steady creatinine levels, and showed no signs of obstruction on ultrasound. This case highlights that treatment with balloon dilation of the calyceal neck appears to be an effective solution that respects the renal parenchyma and function.

MAUDE database and Eustachian tube balloon dilation: Evaluation of adverse events and sales data.

STUDY DESIGN: Review of database. SETTING: Tertiary care neurotology center. PATIENTS: Patients undergoing adverse events. INTERVENTION: MAUDE database evaluation of Eustachian tube balloon dilation (ETBD) for the treatment of Eustachian tube dysfunction. MAIN OUTCOME MEASURES: Medical device reports (MDRs) from the MAUDE database were analyzed for adverse patient events (AE) and device malfunctions (DM) among different devices for ETBD. The objective of this analysis is to assess AE rates and compare them across different devices. Sales data was also used to calculate AE rates. RESULTS: There were 18 MDRs noted in the MAUDE database for patients undergoing ETBD out of an initial 23 results. When separated into devices, the Aera had 9 total MDRs (50 %), Xpress had 8 (44.4 %) and Audion had 1 (5.6 %). There were 10 AE and 8 DM. When separated by device, Aera had 4 AEs and 5 DMs, Xpress had 5 AEs and 3 DMs, and Audion had 1 AE. The most common AE was subcutaneous emphysema (n = 4), in the head and neck region with one report of mediastinal involvement. Using this sales data, the Aera balloon has an MDR rate of 0.0128 % is established, with a rate of AE at 0.0058 %. The Audion balloon had an MDR and AE rate of 0.0164 %. CONCLUSIONS: ETBD is a safe procedure with minimal complications, with subcutaneous emphysema being the most commonly reported adverse event, consistent with literature findings. A comprehensive analysis of AE, coupled with sales data, indicates a commendably low MDR rate of 0.0128 % for the Aera balloon while the Audion balloon had an MDR rate of 0.0164 %. These findings offer valuable insights on post-procedure expectations and engaging in informed consent discussions with patients, highlighting the overall safety of ETBD as an intervention.

Patient-Related Factors Associated With Long-Term Outcomes After Successful Endoscopic Balloon Dilation For Crohn's Disease-Associated Ileo-Colic Strictures: A Systematic Review and Meta-analysis.

Background: Successful Crohn's disease (CD) therapy relies on timely and precise management strategies. Endoscopic balloon dilation (EBD) has been applied as a first-line treatment for symptomatic CD-associated strictures due to its minimally invasive nature and the possibility of preserving intestinal length. Objective: The aim of the present study was to determine patient-related predictive factors associated with the need for surgery for CD-associated ileocolic strictures after technically successful EBD. Methods: All original studies published before December 2023 that reported the outcomes of patients treated with EBD for ileocolic strictures secondary to CD and described follow-up for at least 1 year were included. The difference in risk of needing surgery was calculated for 8 different patient characteristics (Sex, smoking habit, previous surgery, biologic therapy, steroids, immunosuppressors, nature of the stricture, and endoscopic disease activity). Results: There were significant differences in the risk of needing surgery after EBD among patients who underwent surgery and patients without a history of surgery (RD: -0.20 [-0.31, -0.08]), patients with endoscopic mucosal activity and patients in remission at the time of EBD (RD: 0.19 [0.04, 0.34]), patients using biologics at the time of EBD and patients not using biologics (RD: -0.09 [-0.16, -0.03]), and patients using steroids and those not using steroids at the time of EBD (RD: 0.16 [0.07, 0.26]). Conclusions: The use of biologics and endoscopic disease remission at the time of EBD were protective factors against the need for surgery. No previous surgery or use of steroids at the time of EBD was associated with the need for surgery during follow-up.

Outcomes and Complications of Pediatric Eustachian Tube Dilation Surgery.

OBJECTIVE: To determine whether balloon dilation of Eustachian tube (BDET) improves postoperative audiology and quality of life scores in children with chronic Eustachian tube dysfunction. STUDY DESIGN: Retrospective study. SETTING: Tertiary care pediatric center. METHODS: Eligible participants were patients 8 years or older, with a history of 2 prior tubes placement. Group 1-patients completed pre-and post-Eustachian Tube Dysfunction Quality of Life Survey (ETDQ-7) survey scores, Group 2-patients had available pre- and postdilation tympanogram data (TD), and Group 3-patients had both ETDQ-7 survey and TD. The average time for the first and subsequent follow-ups was 3.8 and 12.9 months, respectively. RESULTS: A total of 43 patients (85 ears) underwent BDET. The mean age was 13.3 years (8-18 years). Twenty-four patients were male (55.8%) and over 80% were Caucasian. The average mean ETDQ-7 score before and after dilation was 3.9 and 2.5, respectively. Ninety-three percent experienced improvement of their postoperative ETDQ-7 scores and 53% had normal postdilation ETDQ-7 score (P < .0001). Thirty-seven ears in Group 2 (60.7%) had improvement in postdilation TD. A greater proportion of ears showed improvement of 62.3% with a 95% confidence interval (CI) [50.1%-74.5%] compared to 37.7% without improvement, 95% CI [25.5%-49.87%]. Ears with type A or B TD were more likely to show improvement than ears with type C, perforated, or with tubes (P < .0001). Eighteen out of 30 ears in Group 3 (60%) experienced an improvement in both ETDQ-7 and tympanogram. CONCLUSION: BDET is a safe, efficacious alternative to tubes in selected pediatric patients.

Safety and Efficacy of Covered Self-Expandable Metallic Stent for Choledochojejunal Anastomotic Stricture: A Multi-Center Retrospective Cohort Study.

BACKGROUND: Benign choledochojejunal anastomotic stricture (CJS) is a complication of pancreaticoduodenectomy and choledochojejunostomy. Typically managed with endoscopic balloon dilatation, CJS has a high recurrence rate. Covered metallic stent (CMS) placement is a potential alternative; however, a comprehensive evaluation is lacking. OBJECTIVES: The aim of this study was to evaluate the treatment outcomes of CMS placement in patients with CJS. METHODS: We retrospectively analyzed patients who underwent balloon dilation via endoscopic retrograde cholangiopancreatography using a double-balloon endoscope for CJS between October 2010 and October 2023. The study outcomes included technical and clinical success rates, adverse event rates, choledochojejunal anastomotic stricture recurrence rates, and time to recurrence for balloon dilation and CMS treatment for CJS. RESULTS: There were 43 patients, 55 procedures (40 balloon dilation and 15 CMS placement). The technical and clinical success rates were 100% for both treatments. Recurrence of CJS was observed in 35% (14/40) of the patients in the balloon dilation group. The recurrence rate was significantly higher in the balloon dilation group than in the CMS group (35% vs. 0%, p = 0.006). The time to CJS recurrence was significantly shorter in the balloon dilation group than in the covered metallic stent group (NR vs. NR, p = 0.03). CONCLUSION: Placement of CMS for treating patients with CJS was demonstrated to be an effective and safe method with a lower recurrence rate than balloon dilation.

Effectiveness of intra-arterial manometry in guiding femoral popliteal stent implantation: a prospective randomized controlled trial.

BACKGROUND: Femoropopliteal artery occlusion is a prevalent peripheral arterial disease, and endovascular therapy has become the preferred treatment. Accurate assessment of balloon dilation efficacy is crucial for determining the necessity for subsequent stent implantation. This study aims to investigate the use of interlesion arterial pressure gradients as a novel approach to assess balloon dilation efficacy and guide stent implantation decisions. METHODS: A prospective, randomized, controlled trial was conducted on 100 patients with femoropopliteal artery occlusion. Patients were randomized into a control group (n=50) and an experimental group (n=50). Stent implantation was performed in the control group according to standard indications, while the experimental group underwent stent implantation only if the mean arterial pressure gradient exceeded 10 mmHg or fractional flow reserve (FFR) fell below 0.85. Post-intervention, pressure measurements and angiography were used to evaluate residual stenosis, dissection, and pressure gradients. RESULTS: Lesions were categorized into stent-indicated and non-indicated groups. In the non-stent-indicated lesions, the experimental group demonstrated significantly higher patency rates for lesions with pFFR < 0.85 or ΔP > 10 mmHg compared to the control group (92.9% vs. 50.0%, P=0.039). There was no significant difference in patency rates between the experimental and control groups for stent-indicated lesions. CONCLUSION: Combining pressure measurement with angiography provides a more precise evaluation of balloon dilation efficacy and stent implantation indicators in femoropopliteal artery occlusive disease. Further research is needed to establish optimal pressure threshold values and refine treatment guidelines.

Mechanism of the Immediate Effect of Balloon Dilation Therapy in Spinal Muscular Atrophy With Dysphagia: A High-Resolution Manometric Study.

Balloon dilation therapy (BDT) is used to treat pharyngeal dysphagia in patients with impaired upper esophageal sphincter (UES) relaxation due to cricopharyngeal dysfunction. However, the mechanism underlying this immediate effect remains unclear. Here, we present a case in which we investigated the immediate effects of BDT on UES dysfunction using high-resolution manometry (HRM). A 67-year-old man was diagnosed with spinal muscular atrophy (SMA). He gradually developed dysphagia, and a gastrostomy was performed. Despite continuing oral intake of supplemental nutrition, the patient developed dysphagia. Videofluoroscopic (VF) examination of swallowing revealed pharyngeal residue, while HRM showed weak pharyngeal contractility and impaired UES opening. BDT was performed to address the UES dysfunction. Immediately following BDT, VF demonstrated improved pharyngeal bolus passage. As for the UES function during swallowing, HRM revealed that the UES relaxation duration was significantly longer and the UES nadir pressure was significantly decreased. The patient continued the BDT before oral intake. HRM revealed immediate and prolonged UES opening with decreased UES pressure during swallowing as an immediate effect of BDT. This suggests that these findings represent the mechanisms underlying dysphagia in this patient with SMA. BDT resulted in an immediate improvement in UES function, potentially leading to dysphagia improvement. BDT should be combined with conventional rehabilitation for impaired UES opening. However, further studies are needed to confirm the long-term effectiveness of BDT for dysphagia due to SMA.

Effect of endoscopic sphincterotomy and endoscopic papillary balloon dilation endoscopic retrograde cholangiopancreatographies on the sphincter of Oddi.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP), with its clinical ad-vantages of less trauma and faster recovery, has become the primary treatment for choledocholithiasis. AIM: To investigate the effects of different ERCP procedures on the sphincter of Oddi. METHODS: The clinical data of 91 patients who underwent ERCP at Yixing Hospital of Traditional Chinese Medicine between February 2018 and February 2021 were analyzed retrospectively. The patients were divided into endoscopic sphincterotomy (EST, n = 24) and endoscopic papillary balloon dilation (EPBD, n = 67) groups. The duration of operation, pancreatic development, pancreatic sphincterotomy, intubation difficulties, stone recurrence, and incidence of reflux cholangitis and cholecystitis were statistically analyzed in patients with a history of choledocholithiasis, pancreatitis, and Oddi sphincter dysfunction in the EST and EPBD groups. RESULTS: Differences in hypertension, diabetes, increased bilirubin, small diameter of the common bile duct, or ampullary diverticulum between the two groups were not significant. Statistically significant differences were observed between the two groups concerning sex and age (< 60 years). Patients with a history of choledocholithiasis, pancreatitis, and Oddi sphincter dysfunction were higher in the EST group than in the EPBD group. The number of cases of pancreatic development, pancreatic duct sphincterotomy, and difficult intubation were higher in the EST group than in the EPBD group. The number of Oddi's sphincter manometries, ERCP surgical outcomes, and guidewires entering the pancreatic duct several times in EST group were lower than those in the EPBD group. The numbers of stone recurrences, reflux cholangitis, and cholecystitis were higher in the EST group than in the EPBD group. CONCLUSION: In summary, common bile duct stones, pancreatitis history, and multiple guided wire introductions into the pancreatic duct are independent risk factors for EST and EPBD. Based on this evidence, this study can provide actionable insights for clinicians and researchers.

Clinical efficacy of laparoscopic cholecystectomy combined with endoscopic papillary balloon dilation in treatment of gallbladder stones with common bile duct stones: A retrospective study.

BACKGROUND: The incidence of cholelithiasis has been on the rise in recent years, but the choice of procedure is controversial. AIM: To investigate the efficacy of laparoscopic cholecystectomy (LC) combined with endoscopic papillary balloon dilation (EPBD) in patients with gallbladder stones (GS) with common bile duct stones (CBDS). METHODS: The clinical data of 102 patients with GS combined with CBDS were selected for retrospective analysis and divided into either an LC + EPBD group (n = 50) or an LC + endoscopic sphincterotomy (EST) group (n = 52) according to surgical methods. Surgery-related indexes, postoperative recovery, postoperative complications, and expression levels of inflammatory response indexes were compared between the two groups. RESULTS: Total surgical time, stone free rate, rate of conversion to laparotomy, and successful stone extraction rate did not differ significantly between the LC + EPBD group and LC + EST group. Intraoperative hemorrhage, time to ambulation, and length of hospitalization in the LC + EPBD group were lower than those of the LC + EST group (P < 0.05). The rate of total complications of the two groups was 9.80% and 17.65%, respectively, and the difference was not statistically significant. No serious complications occurred in either group. At 48 h postoperatively, the expression levels of interleukin-6, tumor necrosis factor-α, high-sensitivity C-reactive protein, and procalcitonin were lower in the LC + EPBD group than in the LC + EST group (P < 0.05). At 3 d postoperatively, the expression levels of aspartate transaminase, alanine transaminase, and total bilirubin were lower in the LC + EPBD group than in the LC + EST group (P < 0.05). CONCLUSION: LC combined with EPBD and LC combined with EST are both effective procedures for the treatment of GS with CBDS, in which LC combined with EPBD is beneficial to shorten the patient's hospitalization time, reduce the magnitude of elevated inflammatory response indexes, and promote postoperative recovery.

Invasive Therapeutic Strategies for Stricturing Crohn's Disease in Childhood: A Systematic Review and Meta-Analysis.

BACKGROUND: Crohn's disease (CD) is a chronic inflammatory condition of the gastrointestinal tract. Current drugs are not effective for treating the primary fibrotic component of CD. Recommended invasive treatments include endoscopic balloon dilation, surgery with resection, or strictureplasty. This meta-analysis compared invasive treatment techniques for CD-related strictures in the pediatric population. METHODS: The MEDLINE, EMBASE, and LILACS databases were searched from inception to December 2023. This meta-analysis was performed as per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The outcome was measured by the rate of stenosis recurrence and the adverse events of the techniques. Eligibility criteria were studies that involved the analysis of the recurrence rate of stenosis in pediatric patients with CD requiring surgical intervention after undergoing any of the previously proposed therapies. Additionally, adverse events were analyzed. RESULTS: Three studies comprising a total of 106 endoscopic balloon dilations demonstrated a combined rate of stricture recurrence in patients with CD requiring surgical intervention of 0.171 (95% confidence interval [CI], 0.110-0.255). Three studies comprising a total of 49 surgical resections demonstrated a pooled event rate of 0.100 (95% CI, 0.038-0.240). Finally, 2 studies comprising a total of 38 strictureplasties demonstrated a pooled event rate of 0.347 (95% CI, 0.070-0.789). Concerning adverse events, the most common occurrences were found after surgical resection. CONCLUSIONS: Surgical resection is the best option for treating strictures in pediatric CD patients in terms of recurrence rate, compared with endoscopic balloon dilation and strictureplasty. Nevertheless, surgical resection is associated with more adverse events.

This meta-analysis compares techniques for pediatric Crohn's disease­related strictures. Surgical resection, compared with balloon dilation or strictureplasty, is the best option for treating strictures in these patients in terms of recurrence rate but is associated with more adverse events.

Advancements in Surgical Management of Megaureters.

PURPOSE OF REVIEW: To review and describe the recent evolution of surgery for the various types of pediatric megaureter. RECENT FINDINGS: Megaureter management first relies on determining the underlying cause, whether by obstruction, reflux, or a combination, and then setting appropriate surgical indications because many cases do not require surgery as shown by observation studies. Endoscopic balloon dilation has been on the rise as a major treatment option for obstructive megaureter, while refluxing megaureters can also be treated by laparoscopic and robotic techniques, whether extravesically or transvesicoscopically. During ureteral reimplantation, tapering is sometimes necessary to address the enlarged ureter, but there are also considerations for not tapering or for tapering alternatives. Endoscopic and minimally invasive surgeries for megaureter have been the predominant focus of recent megaureter literature. These techniques still need collaborative prospective studies to better define which surgeries are best for patients needing megaureter interventions.
