Achalasia is a condition that can be treated either by surgery, such as Heller myotomy associated with an antireflux procedure, or by pneumatic dilation, the choice of type of treatment being a widely debated topic nowadays. We selected patients with the diagnosis of achalasia, calculating the Eckardt score on admission and they were treated by pneumatic dilation, respectively by myotomy associated with fundoplication. Therapeutic success at the end of treatment was analyzed, as well as that in subsequent follow-ups. At the same time, other important aspects of the study were quality of life and complications. Forty-eight patients were included, 20 in the group of those treated by pneumatic dilation, and 28 treated by surgery. The results of the therapeutic success were to the advantage of the surgery, both after the completion of the treatment, and in the follow-ups from one year to 2 years (96.4% vs 90%, respectively 92.9% vs. 85%). The quality of life was better in patients with pneumatic dilation throughout the period. Surgical treatment of achalasia has a higher success rate than pneumatic dilation, but the latter is associated with a better quality of life.

Review
BACKGROUND
Restorative proctocolectomy with ileal pouch-anal anastomosis removes the diseased tissue in ulcerative colitis but also allows gastrointestinal continuity and stoma-free living. Pouch strictures are a complication with a reported incidence of 5-38%. The three areas where pouch strictures occur are in the pouch inlet, mid-pouch and pouch-anal anastomosis.
AIM
To undertake a systematic review of the literature and to identify management strategies available for pouch-anal, mid-pouch and pre-pouch ileal strictures and their outcomes.
METHODS
A computer-assisted search of the online bibliographic databases MEDLINE and EMBASE limited to 1966 to February 2016 was performed. Randomized controlled trials, cohort studies, observational studies and case reports were considered. Those where data could not be extracted were excluded.
RESULTS
Twenty-two articles were considered eligible. Pouch-anal strictures have been initially managed using predominately dilators which include bougie and Hegar dilators with various surgical procedures advocated when initial dilatation fails. Mid-pouch strictures are relatively unstudied with both medical, endoscopic and surgical management reported as successful. Pouch inlet strictures can be safely managed using a combined medical and endoscopic approach.
CONCLUSION
The limited evidence available suggests that pouch-anal strictures are best treated in a stepwise fashion with initial treatment to include digital or instrumental dilatation followed by surgical revision or resection. Management of mid-pouch strictures requires a combination of medical, endoscopic and surgical management. Pouch inlet strictures are best managed using a combined medical and endoscopic approach. Future studies should compare different treatment modalities on separate stricture locations to enable an evidenced-based treatment algorithm.

Observational Study
OBJECTIVES
Tracheal stenosis is a debilitating condition that often presents as an emergency and is challenging to treat. Dilatation may avoid tracheostomy or costly tracheal resection and reconstruction. Traditional dilators cause complete occlusion, preventing oxygenation and ventilation, limiting the safe duration of dilatation, and increasing the risk of hypoxic injury or barotrauma. The study authors here assessed an innovative nonocclusive tracheal dilatation balloon, which may improve patient safety by allowing continuous gas exchange.
DESIGN
A prospective observational study of 20 discrete dilatation procedures performed in 13 patients under general anesthesia. The primary outcomes were the ability to ventilate during dilatation and the preservation of peripheral oxygen saturation. Secondary outcomes included a measured reduction in stenosis, improvement in Cotton-Myer grading, and procedure-related adverse events.
SETTING
At a single university (academic) hospital.
PARTICIPANTS
Consenting adult patients with acquired tracheal stenosis.
INTERVENTIONS
Access to the airway was maintained by a rigid bronchoscope or supraglottic airway device, as deemed appropriate. Continuous conventional ventilation was provided during 3-minute balloon dilatations.
MEASUREMENTS AND MAIN RESULTS
Heart rate, airway pressure, end-tidal carbon dioxide partial pressure, and peripheral oxygen saturation were measured, and adverse events were recorded. Ventilation was satisfactory in all patients. Peripheral saturation remained greater than 94% in 19 of the 20 (95%) procedures. Stenosis internal diameter and grading were improved. Two patients had minor reversible adverse events (coughing and laryngospasm), which did not prevent completion of the procedure.
CONCLUSIONS
The authors report the first human trial of the device, in which continuous conventional ventilation could be provided during all tracheal balloon dilatation procedures. Larger trials are needed to confirm improved patient safety and comparative efficacy.

Comparative Study
Esophageal dilatations are commonly performed in pediatric patients who have undergone an esophageal atresia/tracheoesophageal fistula (EA/TEF) repair or following caustic injury. We sought to compare the practice of esophageal dilatation across different specialties. We analyzed all patients who had an esophageal dilatation at our center between April 2014 and December 2018. Patients were identified via prospectively maintained databases and clinical coding records. Patients had a combination of dilatations under each specialty: interventional radiology (IR), surgery, and gastroenterology. Thirty-five individual patients underwent 226 dilatations, median dilatations per patient was 3 (1-40). The median age at first dilatation was 18 months (1-194 months). Sixty-eight percent of patients had a previous EA/TEF repair. IR performed 59% of dilatations, surgeons 26%, and 15% by gastroenterologists. Surgeons more frequently were performing initial dilatations ( < .05) and performed more dilatations in EA/TEF patients ( < .0001). There was a significant difference between the time from a surgical dilatation until the next dilatation, 3.7 months, compared with an IR dilatation, 1.8 months (ANOVA, < .05). Surgeons more frequently increased the size of balloon used (57% versus 33% versus 39%, < .01). There was no significant difference in balloon size between specialties or in the incremental increase in size between subsequent dilatations. There was one postprocedure perforation, managed conservatively (complication rate = 0.4%). We have demonstrated that on average, patients wait longer after a surgical dilatation until their next procedure, and surgical teams are more likely to increase the size of the dilating balloon. Surgeons tend to be more involved in their postoperative patients in the initial phases of stricture management. Our results suggest the feasibility and safety of a multispecialty approach for these patients.

Comparative Study Review
The nasal valve deserves relevant in patients presenting with nasal obstruction. In particular, the nasal valve plays an important role in nasal airflow control, it is relevant for the otolaryngologist to not only consider but also fully evaluate the nasal valve when seeing a patient with nasal obstruction. These data reported in this Supplement confirms the clinical relevance of the nasal valve in different groups of patients and normal subjects. In fact, an integrity of nasal valve is fundamental to ensure a physiological nasal breathing that in turn guarantees a correct pulmonary function. The possibility to use the non-surgical and well-accepted option constituted by the nasal internal dilator represent an interesting opportunity for both the physician and the patient.

Review
PURPOSE
Congenital esophageal stenosis (CES) associated with esophageal atresia (EA) is rare, and no standard treatment has been established. We reviewed cases of EA-associated CES to assess the clinical characteristics and treatment outcomes, especially the feasibility of endoscopic dilatation.
METHODS
We retrospectively examined patients with EA-associated CES. We also compared treatment outcomes of EA-associated CES with those of EA patients without CES who developed postoperative anastomotic stricture.
RESULTS
Among 44 patients with EA, ten had CES (23%). Postoperative complications were not significantly different between EA patients with CES and those without CES but with anastomotic stricture. All CES patients underwent balloon dilatation as initial treatment. Eight of nine patients (89%) were successfully treated by dilatation only, and one patient underwent surgical resection. The median number of balloon dilatations for CES was five (2-17), which was higher than that for anastomotic stricture in patients without CES (p = 0.012). Esophageal perforation occurred in five patients with CES (5/9, 56%) after dilatation, but all perforations were successfully managed conservatively with an uneventful post-dilatation course.
CONCLUSIONS
Twenty-three percent of patients with EA had CES. Although balloon dilatation for EA-associated CES required multiple treatments and carried a risk of perforation, balloon dilatation showed an 89% success rate and all perforations could be managed conservatively.

Ascending aortic (AoAsc) dilatation can lead to acute aortic syndromes and has been described in various familial cardiac diseases. Its prevalence and clinical significance in patients with noncompaction cardiomyopathy (NCCM) are however unknown. Establishing the prevalence can facilitate recommendations on routine screening in NCCM. In this cross-sectional cohort study based on the Rijnmond Heart Failure/Cardiomyopathy Registry, the patient were enrolment between 2014 and 2021. All NCCM patients (n = 109) were age and sex matched with 109 dilated cardiomyopathy (DCM) patients as controls. The aortic diameters were measured through the parasternal long-axis transthoracic echocardiographic view at the sinuses of valsalva (SoV-Ao), sinotubular junction (STJ) and ascending aorta (AscAo). Dilatation was defined using published criteria adjusted for body surface area (BSA), sex, and age. Median age of age-sex matched NCCM and DCM patients was 45[31-56] vs. 45 [31-55] years with 53% males in both groups. NCCM patients had more familial hereditary patterns and genetic variants (55% vs. 24%, p < 0.001). DCM patients had more heart failure and left ventricular dysfunction (ejection fraction 34 ± 11 vs. 41 ± 12, p = 0.001). Ascending aortic dilatation was present in 8(7%) patients with NCCM and 5(5%) patients with DCM (p = 0.46). All dilatations were classified as mild. In conclusion, in this cross-sectional cohort study the prevalence of ascending aortic dilatation in NCCM patients was 7%, which were only mild dilatations and not significantly different from an age-sex matched cohort of DCM patients. Routine aortic dilatation screening therefore does not seem warranted in patients with NCCM.

BACKGROUND/PURPOSE
There are some studies about the effect of postoperative anal dilatation on anastomotic stenosis and Hirschsprung-associated enterocolitis (HAEC), but we have not seen any report about preoperative anal dilatation. We hypothesized that preoperative anal dilatation could reduce the incidence of HAEC and facilitate the operation. We aim to compare the HAEC rates and postoperative complications between groups who either had or did not have anal dilatations (AD or NAD) prescribed before laparoscopic-assisted Soave pull-through procedures for Hirschsprung disease (HD); by this means, we will evaluate the benefit of dilatations before the surgery for HD.
METHODS
A retrospective review of children with HD operated in our hospital between 2014 and 2018 was performed. Those with 21 trisomy, total colonic aganglionosis, multiple stage procedures, serious congenital malformations, and lost to follow-up were excluded. Patients were divided into preoperative anal dilatation group (AD group) and no preoperative anal dilatation group (NAD group). Routine anal dilatation was performed in both groups from 2 weeks after laparoscopic-assisted Soave pull-through. The anal dilatation was carried out daily with metal anal dilators with size appropriate to the age of the child. The size of the anal dilators was increased by 1 mm every 2 weeks for at least 3 months. Demographic data, operation time, pre- and postoperative HAEC rates and postoperative obstructive symptoms between groups were compared. Significance was considered at P < 0.05.
RESULTS
There were 95 children (17 female and 78 male) included, 36 AD and 59 NAD. There was no significant difference in demographic data between the two groups. The incidence of HAEC between the groups was not different both preoperatively (14% vs. 24%, P = 0.298) and postoperatively (11% vs. 19%, P = 0.171). The postoperative obstructive symptoms rates were 19% versus 22% for the AD and NAD groups, respectively (P = 0.802). The operation time of group AD was significantly shorter than that of group NAD (P = 0.008). Preoperative anal dilatation could shorten the operation time in short and typical-segment (2.08 ± 0.39 vs. 2.67 ± 0.37, P = 0.009 and 3.05 ± 0.38 vs. 3.29 ± 0.46, P = 0.042), but has no significant effect on long-segment disease (3.85 ± 0.41 vs. 3.89 ± 0.30, P = 0.839).
CONCLUSION
We have not shown a reduced risk of developing HAEC or postoperative obstructive symptoms if anal dilatations are prescribed before surgery. However, it may decrease the difficulties of surgeries, so the operative time is shortened.

Review
The creation of the access is one of the main steps in percutaneous nephrolithotomy, the most complicated for many urologists and the one that limited most the universalization of the technique. From a purely technical point of view, it includes puncture of the excretory tract and dilatation of the percutaneous tract to end with the introduction of an Amplatz type working sheath. The objective of the puncture is to try to access the excretory system through the renal papilla, minimizing the risk of bleeding. The puncture may be guided by ultrasound, fluoroscopy, both, under endoscopic or laparoscopic control, by CT scan or MRI, or even by application of new technologies (Robotic, augmented reality, electromagnetic navigation,...). Due to the versatility and independence involved in having the ability to perform the renal puncture in the operative room, as well as its influence in the results of PCNL, it must be the urologist himself who performs this basic step of percutaneous surgery. The tract may be dilated by Alken type metallic dilators, semirrigid Amplatz type dilators or high pressure balloons. To date, there is no single ideal dilatation method, being the selection based on the endourologist's experience and the knowledge of the advantages and limitations of each option. The objective of this review is to present the main methods for puncture guiding and tract dilatation for PCNL, as well as to provide technical details to improve its result.
