Objective of this work is to evaluate interventional radiology modalities such as balloon catheter dilation (BCD) and stent insertion, as minimally invasive methods in treatment uretero-enteral anastomotic strictures. Material and method: Retrospective study enrolled 26 patients (pts) in whom percutaneous BCD (17 pts) and metal stent implantation (9 pts) were done. Study was conducted from June 2005 till August 2007 and included total amount of 470 pts operated during 4 year period from 2003 till 2007. In 26 pts 35 ureteral units were treated, all of them in ambulatory conditions under oral analgosedation, monitored by fluoroscopy. Percutaneous BCD or stent implantation was performed in 24 pts and in 2 pts combined antegrade- retrograde approach for stent delivery, was applied. In all cases percutaneous nephrostomy (PCN) was left for 7 days period after procedure but in 6 units (5 pts) it remained permanent solution. First check up was done 7 days after by contrast media injection through nephrostomy tube prior to its extraction. Second control was done 30 days after by ultrasound exam and the last control (3 months after) by intravenous urography (IVU). Results: In our specimen 17pts had strictures unilaterally (65.4%) and in 9 pts (34.6%) it occurred bilaterally. First check up revealed 82.7% success of BCD, in 17.3% BCD was repeated with the final success rate of 73.5% (19/26). In four pts (26.5%) after BCD reobliteration happened and PCN was left. Patent ureteral lumen was observed in 6 pts (85.7%) with stent inserted while one pt underwent surgical reintervention. No significant difference between BCD and stent insertion success rate was noticed, based upon morphological parameters (ureteral lumen diameter, pelvicaliceal system dilatation) and serum creatinin level. Conclusion: BCD and stent insertion showed satisfactory results (following 3 months) in ureteroenteral anastomotic stricture recanalization. They include ambulatory conditions, ability to repeat procedure, without complications -excluding restenosis which finally can be surgically treated.

Objectives To compare the clinical outcomes of patients undergoing additional procedures in endoscopic endonasal dacryocystorhinostomy (End-DCR) surgery and discuss the factors affecting the success of End-DCR surgery in light of relevant literature. Methods The study included 155 patients who underwent End-DCR surgery in our clinic due to epiphora. This was a prospective randomized, single-blind, controlled trial. Group I (control) included 54 patients who did not undergo silicone stent insertion or silver nitrate application, group II included 51 patients who underwent silicone stent insertion only, and group III included 50 patients who underwent silver nitrate application only. Statistical analysis was performed on follow-up data regarding anatomic and functional success rates. Results Revision surgery was performed in 16 patients who developed persistent epiphora in the postoperative period, including 6 in group I, 7 in group II, and 3 in group III ( P = .4). The most common reason for revision surgery was stenosis of the neo-ostium ( n = 8), followed by granulation tissue formation ( n = 5) and synechia formation ( n = 3). Granuloma formation was the most common postoperative complication, and a significant difference was found among the groups with regard to granuloma formation ( P = .04). At postoperative month 12, the functional success rate was estimated to be 88%, 86%, and 94%, and the anatomic success rate was estimated to be 94%, 92%, and 96% in groups I, II, and III, respectively, with no significant difference, found among the 3 groups with regard to both rates ( P = .79 and P = .76, respectively). Conclusion The results indicated that stenting and silver nitrate application did not affect surgical success. Our preliminary results on silver nitrate cauterization showed that it is an effective, inexpensive, and practical method to reduce granulation formation in the postoperative period.

Spinal stenosis is a common condition in elderly individuals. Many patients are unresponsive to the conventional treatment. If the transforaminal epidural block does not exert a sufficient treatment effect, percutaneous transforaminal epidural adhesiolysis (PTFA) through the safe-triangle approach using an inflatable balloon catheter can reduce the patients’ pain and improve their functional capacity. We aimed to evaluate the safety and efficacy of the Kambin’s-triangle approach for PTFA using an inflatable balloon catheter and compare this approach to the traditional safe-triangle approach. Thirty patients with chronic unilateral L5 radiculopathy were divided into two groups: the safe-triangle-approach and Kambin’s-triangle-approach groups, with 15 patients each. The success rate of the procedure was assessed. Pain and dysfunction were assessed using the Numerical Rating Scale and Oswestry Disability Index, respectively, before the procedure and at 1 and 3 months after the procedure. The success rate of the procedure was high in both the groups, with no significant difference between the groups. The Numerical Rating Scale and Oswestry Disability Index scores significantly decreased 3 months after the procedure in both the groups, with no significant difference between the groups. For patients in whom the safe-triangle approach for PTFA is difficult, the Kambin’s-triangle approach could be an alternative.

Abstract Aim of the Study The aim of this study was to provide an overview of endoscopic treatment in children after reconstruction of esophageal atresia. Methods This study, conducted at a single tertiary center, reviewed patients requiring endoscopic treatment during a 15-year period, from 2004 to 2018. Collected data include number, frequency, complications, and effectiveness of esophageal anastomotic dilations. Results A total of 55 children with esophageal atresia (EA) underwent upper gastrointestinal endoscopy. Of those, 37 required therapeutic endoscopy with dilation procedures for anastomotic strictures. Thirty-five patients underwent dilations using only through-the-scope (TTS) balloon (BD),1 patient using only a Savary bougie (SB), and 1 using both. A total of 126 dilations were performed using BD in 36 patients and 6 dilations using SB in 2 patients. Specifically, in children treated only with BD were performed 1 dilation in 6 children (17.1%), 2 in 6 children (17.1%), 3 in 7 children (20%), 4 in 6 children (17.1%), 5 in 6 children (17.1%), 7 in 2 children (5.7%), and 8 in 2 children (5.7%). Balloon catheter sizes ranged from 6 mm to 15 mm. In 2 patients (5.4%) stents were placed, 1 and 6 stents, respectively. Intralesional triamcinolone was injected in 8 patients (21.6%) as additional therapy. Major complications included perforation in 4 patients (10,8%), resolved with conservative treatment. All patients had clinical improvement in the follow-up. Conclusion Currently, endoscopic treatment for esophageal anastomotic stricture is the first procedure adopted in clinical practice after the surgical approach, since it is regarded safe and effective. Balloon dilations are preferred in our overview as a treatment option for esophageal anastomotic strictures. Symptom relief is reported in all cases, while the rate of complications is very low. Sometimes, refractory strictures influence the patient's quality of life and therapeutic alternatives such as stent placement should be considered.

Background and Objectives. Benign strictures are the main cause of esophageal strictures in children. They can be managed by different modalities but endoscopic dilatation is the standard therapy. This study is aimed at reviewing the efficacy and safety of endoscopic dilatations in children with esophageal strictures. Materials and Methods. In this retrospective cross-sectional single center study, records of patients with esophageal strictures presented to the pediatric department, Salmaniya Medical Complex, Bahrain, in the period between 1995 and 2019 were reviewed. Demographic data, indications of endoscopic dilatations, the procedure success rate, and possible complications were assessed. Results. Forty-six children were found to have esophageal strictures. Twenty-five (54.3%) patients were males. Most patients presented during infancy (86.5%, 32/37 patients). Twenty-six (56.5%) patients required 88 dilatation sessions, while the remaining 20 (43.5%) patients did not require dilatations. The median number of dilatation sessions per patient was three (interquartile range = 2 –5). Savary-Gilliard bougienages were the main dilators used (80.8%, 21/26 patients). Anastomotic stricture (post esophageal atresia/tracheoesophageal fistula repair) was the main cause of esophageal strictures and was found in 35 (76.1%) patients. Patients with nonanastomotic strictures had more frequent dilatations compared to those with anastomotic strictures ( P = 0.007 ). The procedure success rate was 98.8%. Yet, it was operator dependent ( P = 0.047 ). Complete response to dilatation was found in 18 (69.2%) patients, satisfactory in seven (26.9%), and an inadequate response in one (3.9%). Those with satisfactory responses still require ongoing dilatations based on their symptoms and radiological and endoscopic findings. No perforation or mortality was reported. Patients with dilatations had more recurrent hospitalization ( P < 0.0001 ), more dysphagia ( P = 0.001 ), but shorter hospital stay ( P = 0.046 ) compared to those without dilatations. Surgical intervention was required in one patient with caustic strictures. The median follow-up period was six years (interquartile range = 2.25 –9.0). Conclusions. Endoscopic esophageal dilatation in children with esophageal strictures is effective and safe. Yet, it was operator dependent. Nonanastomotic strictures require more dilatations compared to anastomotic strictures. Findings of this study are comparable to those reported worldwide.

Abstract Aim Approximately a third of all colorectal cancers diagnosed in the UK each year are rectal in origin and will undergo surgical resection with formation of an anastomosis. Focus is placed on techniques to ensure anastomotic integrity however an anastomotic leak, pelvic sepsis, distance to the anal verge and stapler choice are all established risk factors for the formation of a benign anastomotic stricture. This review aimed to assess the use of endoscopic salvage techniques in an attempt to avoid surgical re-intervention. Method A literature search was performed for published full text articles using the PubMed, Cochrane and Scopus databases. Additional papers were detected by scanning the references of relevant papers. Results A total of 40 papers were included focusing upon balloon dilation, stent insertion, electroincision, stapler stricturoplasty and corticosteroid use. Endoscopic balloon dilatation remains the most commonly used technique in the management of anastomotic strictures, with a low complication rate despite the frequent requirement for repeated dilatations. Although established in the role for malignant obstruction, stent insertion is yet to gain an established role in the benign setting. Conclusions Benign anastomotic strictures can be a significant problem post-rectal resection, impacting upon quality of life and requiring repeated intervention. Endoscopic management should be utilised in the primary setting to avoid surgical re-intervention. Standardisation of these methods is imperative in establishing the best modality of treatment. For refractory strictures a low threshold of suspicion for malignant recurrence should be maintained.

Objective: To evaluate the safety and efficacy of endoscopic procedures for ureteroenteric anastomotic strictures (UESs) after radical cystectomy and urinary diversion.Methods: We performed a meta-analysis of relevant articles through March 2020 using PubMed, Embase, and Cochrane Central Register to assess the efficacy of endoscopic procedures in UES according to the PRISMA and PICOS criteria. The main endpoints were success rate and complications, and we also compared the efficacy of different methods and stricture length and side in UES. Cochrane Collaboration's Revman version 5.3 and Stata version 15.1 software were used for statistical analysis.Results: A total of 18 retrospective studies with 697 patients were included. The median follow-up ranges from 12 to 62.5 months. Patients treated with endoscopic procedures had an overall success rate of 46%. The pooled rate of Clavien–Dindo ≥ 3 complications was 3.8% among included studies. Laser vaporization and stent insertion (48 and 47%) had a relatively high success rate than balloon dilatation (35%). In subgroup analysis, the success rate of endoscopic procedures for ≤ 1-cm strictures was significantly higher than that for &gt;1-cm ones [odds ratio (OR), 8.65; 95% confidence interval (CI), 3.53–21.21; P &lt; 0.00001]. In addition, the success rate in cases with strictures of the right side was relatively higher than that in cases with strictures of the left side (OR, 1.72; 95% CI, 1.05–2.81; P = 0.03).Conclusion: Our pooled studies showed that endoscopic operation is feasible and associated with a moderate success rate along with a relatively low incidence of perioperative complications in the treatment of UES, especially with length ≤ 1 cm and right side. Although there is still no consensus on endoscopic technique for UES regarding balloon dilatation, stent insertion, and laser vaporization, we believe that endoscopic management is a safety and available approach for UES with close follow-up.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Abstract Purpose To determine the impact of failed ab-interno trabeculectomy on the postoperative outcome of subsequent XEN45 gel stent (Allergan, CA, USA) implantation in pseudophakic eyes. Methods In this retrospective single-center study, we included 60 pseudophakic eyes from 60 participants who underwent XEN45 gel stent implantation. Thirty eyes each underwent primary stent implantation (control group) or had previously undergone a failed ab-interno trabeculectomy (trabectome group). The groups were matched at a 1:1 ratio based on the following criteria: preoperative and maximum Intraocular pressure (IOP), preoperative medication score, cup/disk-ratio, follow-up time, best-corrected visual acuity at baseline, age, and the proportion of patients classified as primary open angle glaucoma or exfoliation glaucoma. We defined a successful surgery by the following three scores: an IOP reduction > 20% and IOP at the longest follow-up < 21 mmHg (Score A) or < 18 mmHg (Score B) or IOP ≤ 15 mmHg and an IOP reduction ≥ 40% (Score C). One open conjunctival revision was allowed in all scores, and a repeat surgery was considered a failure. Results Following an average follow-up period of 22 ± 12 months, we observed a mean IOP reduction of 38%, from 23.5 ± 5.2–14.5 ± 5.0 mmHg. Comparative analyses between the groups did not reveal a significant difference in the postoperative IOP, postoperative medication score, side effects, revision rate, repeat surgery rate, or success rate. Conclusions Trabectome is a viable first-line procedure for medically uncontrolled glaucoma before filtering ab-interno microstent surgery is considered.

This study investigated the perception and learning of relative pitch using vibrotactile stimuli by musicians with and without a hearing impairment. Notes from C3 to B4 were presented to the fingertip and forefoot. Pre- and post-training tests in which 420 pairs of notes were presented randomly were carried out without any feedback to participants. After the pre-training test, 16 short training sessions were carried out over six weeks with 72 pairs of notes per session and participants told whether their answers were correct. For amateur and professional musicians with normal hearing and professional musicians with a severe or profound hearing loss, larger pitch intervals were easier to identify correctly than smaller intervals. Musicians with normal hearing had a high success rate for relative pitch discrimination as shown by pre- and post-training tests, and when using the fingertips, there was no significant difference between amateur and professional musicians. After training, median scores on the tests in which stimuli were presented to the fingertip and forefoot were >70% for intervals of 3–12 semitones. Training sessions reduced the variability in the responses of amateur and professional musicians with normal hearing and improved their overall ability. There was no significant difference between the relative pitch discrimination abilities between one and 11 semitones, as shown by the pre-training test, of professional musicians with and without a severe/profound hearing loss. These findings indicate that there is potential for vibration to be used to facilitate group musical performance and music education in schools for the deaf.

Pyelonephritis (PN) represents an important cause of morbidity in the pediatric population, especially in uropathic patients. The aim of the study is to demonstrate differences between PNs of uropathic patients and PNs acquired in community in terms of uropathogens involved and antibiotic sensitivity; moreover, to identify a proper empiric therapeutic strategy. A retrospective study was conducted on antibiograms on urine cultures from PNs in vesicoureteral reflux (VUR) patients admitted to pediatric surgery department and from PNs in not VUR patients admitted to Pediatric Emergency Unit between 2010 and 2020. We recorded 58 PNs in 33 patients affected by VUR and 112 PNs in the not VUR group. The mean age of not VUR patients at the PN episode was 1.3 ± 2.6 years (range: 20 days of life–3 years), and almost all the urine cultures, 111 (99.1%), isolated Gram-negative bacteria and rarely, 1 (0.9%), Gram-positive bacteria. The Gram-negative uropathogens isolated were Escherichia coli (97%), Proteus mirabilis (2%), and Klebsiella spp. (1%). The only Gram-positive bacteria isolated was an Enterococcus faecalis. As regards the antibiograms, 96% of not VUR PNs responded to beta-lactams, 99% to aminoglycosides, and 80% to sulfonamides. For the VUR group, mean age was 3.0 years ± 3.0 years (range: 9 days of life–11 years) and mean number of episodes per patient was 2.0 ± 1.0 (range: 1–5); 83% of PNs were by Gram-negatives bacteria vs. 17% by Gram-positive: the most important Gram-negative bacteria were Pseudomonas aeruginosa (44%), Escherichia coli (27%), and Klebsiella spp. (12%), while Enterococcus spp. determined 90% of Gram-positive UTIs. Regimen ampicillin/ceftazidime (success rate: 72.0%) was compared to ampicillin/amikacin (success rate of 83.0%): no statistically significant difference was found (p = 0.09). The pathogens of PNs in uropathic patients are different from those of community-acquired PNs, and clinicians should be aware of their peculiar antibiotic susceptibility. An empiric therapy based on the association ampicillin + ceftazidime is therefore suggested.
