Comparative Study Randomized Controlled Trial
INTRODUCTION AND OBJECTIVES
Data on the use of single step dilatation technique during pediatric percutaneous nephrolithotomy (PCNL) in the literature is sparse. In this prospective randomized study, we aimed to compare the safety, efficacy, and perioperative complications of single step versus serial tract dilatation using Alken metal telescopic dilators during pediatric PCNL.
METHODS
Patients undergoing PCNL were randomized into two groups according to the dilatation technique used. In group A, Alken telescopic serial metal dilatation was utilized, and in group B, single step dilatation was performed. Inclusion criteria included children < 18 years with stone burden from 2 to 4 cm, located in the renal pelvis ± one calyx, who were candidates for PCNL. The primary outcomes were access time and complications' rate. The secondary outcomes were dilatation fluoroscopy time, operative duration, stone free rate, postoperative hospital stay, hemoglobin deficit, and need for blood transfusion. Both outcomes were evaluated and compared between both treatment groups.
RESULTS
A total of 70 patients were randomized into group A (35 patients) and group B (35 patients). Access was successfully obtained in all procedures. All the procedures were performed through a single tract. Access time and dilatation fluoroscopy time were shorter in group B (statistically significant). Patients in group A had higher rate of complications (statistically significant). Intraoperative bleeding requiring blood transfusion was less in single track dilatation than serial metal track dilatation.
CONCLUSIONS
Compared to serial metal track dilatation, single step dilatation showed comparable operative time and stone free rate, with significantly reduced access time and dilatation fluoroscopy time.

Observational Study
OBJECTIVES/HYPOTHESIS
To better assess rates of postoperative complications and mortality following esophageal dilation, and to identify factors associated with adverse outcomes.
STUDY DESIGN
Observational, retrospective cohort study.
METHODS
We queried a national database of insurance claims for Current Procedural Terminology (CPT) codes representing esophageal dilation performed between 2011 and 2017. Patients aged 18 to 100 who were continuously enrolled with their insurance provider were included. Demographic information, additional CPT codes, concomitant diagnoses, and anticoagulant medication data were collected for all patients included. Postoperative mortality was assessed and International Classification of Diseases (ICD)9/10 codes for complications, including esophageal perforation, hemorrhage, mediastinitis, and sepsis were flagged.
RESULTS
We identified 202,965 encounters for esophageal dilation. Of these procedures, 193 were performed on a patient who underwent percutaneous endoscopic gastrostomy (PEG) during the study period and was analyzed separately. Another 244 dilations were excluded due to repeat entries. Of the remaining 202,528 procedures remaining, 42,310 were repeat dilations in the same patient. Data analysis was confined to each patient's initial dilation. 160,218 initial dilations remained. Of these, 62,107 were performed on male patients and 98,111 were performed on female patients. The average age was 57.7 years. There were 12 mortalities within 30 days postoperatively, representing 0.0075% of all dilations. Esophageal perforation and esophageal hemorrhage were the most common reported complications, with 139 and 110 occurrences, respectively. The overall per-dilation complication rate was 0.215%.
CONCLUSIONS
Evidence from a national insurance claim database suggests that esophageal dilation is a safe procedure with a low rate of serious complications and a 30-day all-cause mortality rate of less than 1 per 10,000 dilations.

Review
INTRODUCTION
Vaginal dilators are often prescribed to facilitate an adaptive brain-body connection to decrease anxiety and pain that can be experienced in anticipation of sexual intercourse among populations of women with sexual pain syndromes. Postmenopausal women, cancer survivors, and women with a wide variety of pelvic floor disorders who experience genito-pelvic pain/penetration disorder (GPPPD) are often advised to incorporate vaginal dilators into their pelvic floor rehabilitation program and treatment regimens to enable penetrative intercourse with less pain. However, little is known about the behaviors of dilator users, what treatment protocols are most effective, how patients are currently using their dilators, and how effective are clinicians in helping their patients achieve success with their dilation therapy.
METHODS
A recent PubMed literature search was performed using the key words vaginal dilator, vaginal dilator therapy, sexual quality of life, vaginal stenosis, vaginal dilation, vaginismus. A total of 29 English articles were reviewed and summarized. Articles were excluded for the following reasons: not in English and unrelated to dilator therapy.
MAIN OUTCOME MEASURE
This article will summarize the current research on vaginal dilators and discuss needs for future research to maximize patients' compliance and success with this treatment. Much of the summary data regarding user behavior will come from the early survey data with Milli, a novel, patient-controlled electronic dilator that slowly expands 1 mm at a time from its smallest diameter, 15 mm to a maximum diameter of 40 mm. Milli is currently being used by more than 1,000 women, and 3-month follow-up data were recorded on 335 of those patients.
RESULTS
Dilators exist in multiple forms (plastic, latex, and medical grade material), may come individually or in sets, and many have special features such as vibration or the ability to be heated or cooled before use. Little is known about patients' use of dilators and the Milli's 3-month survey serves as an insight to patient dilator behavior. The most common medical goals for patients undergoing dilation treatment were return to penetrative intercourse and pain reduction during coitus. Patients were dilated on average 2.72 days/week; 56.8% of patients had suffered from sexual pain for 2 or more years and 36.3% had previously used static dilators. More than 70% of Milli users purchased Milli and are using Milli without the direct guidance of a clinician. The most common emotions patients used to describe their treatment were not only "anxious," "frustrated," but also "empowered" and "optimistic." The most common dilatory session duration was 6-10 minutes, mostly in the evening/bedtime (68.3%), located in the bedroom (96.8%). Adjunctive treatment included the following: vaginal moisturizers, local estrogen products, coital lubricants, and genital pelvic floor physical therapy. During the dilation sessions, women most often watched TV/videos, practiced mindfulness, or listened to soothing music. Factors that showed trends toward improved patient outcomes were length of dilation treatment (greater than 3 months) and use of meditation and soothing music. Factors not associated with improvement trends were as follows: when/where patients dilated and patient demographics including age, race, or religious preferences.
CONCLUSION
Patients who purchase dilators have often suffered with their condition for a long time and had difficulty finding a competent health-care clinician well versed in sexual pain syndromes that can help them. When patients did find a clinician, there were no clinically proven standardized protocols or formalized guidelines to give to patients about how to best use their dilators. Larger long-term interventions investigating a standardized dilation protocol are planned in future studies to better elucidate the effective and optimal dilation treatment plans.

Review
PURPOSE OF REVIEW
Benign strictures of the esophagus, caused by various causes, are frequently encountered in clinical practice. Although endoscopic dilation is still the standard and first-line therapy, complex and difficult esophageal strictures are still encountered and remain a challenge to endoscopists. The main scope of this review article is to offer a closer look at the different endoscopic modalities and approaches to complex and difficult esophageal strictures.
RECENT FINDINGS
In the past few years, endoscopic dilatation, stents including self-expandable and biodegradable types, incisional therapy, and pharmacological treatments have been utilized in the prevention and management of refractory and recurrent esophageal strictures. Meanwhile, more recent techniques such as the BougieCap, percutaneous transgastric endoscopic myotomy, through-the-scope stents, radial incision and cutting, etc. have been developed as alternative methods. A number of studies utilizing these newer methods have shown promising results in the treatment of complex and difficult esophageal strictures.
SUMMARY
Endoscopic treatment of refractory, complex and difficult esophageal strictures still remains to be a challenge for many endoscopists. While balloon or bougie dilatation still remains to be the first-line approach, other techniques have emerged as treatment alternatives and may become adjunct therapy to endoscopic dilatation.

: Functional gastric stenosis, a consequence of sleeve gastrectomy, is defined as a rotation of the gastric tube along its longitudinal axis. It is brought on by gastric twisting without the anatomical constriction of the gastric lumen. During endoscopic examination, the staple line is deviated with a clockwise rotation, and the stenosis requires additional endoscopic manipulations for its transposition. Upper gastrointestinal series show the gastric twist with an upstream dilatation of the gastric tube in some patients. Data on its management have remained scarce. The objective was to assess the efficacy and safety of endoscopic balloon dilatation in the management of functional post-sleeve gastrectomy stenosis. : Twenty-two patients with functional post-primary-sleeve-gastrectomy stenosis who had an endoscopic balloon dilatation between 2017 and 2023 were included in this retrospective study. Patients with alternative treatment plans and those undergoing endoscopic dilatation for other forms of gastric stenosis were excluded. The clinical outcomes were used to evaluate the efficacy and safety of balloon dilatation in the management of functional gastric stenosis. : A total of 45 dilatations were performed with a 30 mm balloon in 22 patients (100%), a 35 mm balloon in 18 patients (81.82%), and a 40 mm balloon in 5 patients (22.73%). The patients' clinical responses after the first balloon dilatation were a complete clinical response (4 patients, 18.18%), a partial clinical response (12 patients, 54.55%), and a non-response (6 patients, 27.27%). Nineteen patients (86.36%) had achieved clinical success at six months. Three patients (13.64%) who remained symptomatic even after achieving the maximal balloon dilation of 40 mm were considered failure of endoscopic dilatation, and they were referred for surgical intervention. No significant adverse events were found during or following the balloon dilatation. : Endoscopic balloon dilatation is an effective and safe minimally invasive procedure in the management of functional post-sleeve-gastrectomy stenosis.

Review
Medical and surgical methods can both be recommended for second trimester abortion (after 12-weeks of gestational age). Induced abortion with a mifepristone and misoprostol regimen is the preferred approach; where mifepristone is not available, misoprostol alone for medical abortion is also effective. Dilation and evacuation (D&E) is the procedure of choice for surgical abortions, and adequate cervical preparation contributes significantly to safety. Availability of drugs and instruments, ability to provide pain control, provider skill and comfort, client preference, cultural considerations, and local legislation all influence the method of abortion likely to be performed in a given setting. Both surgical and modern medical methods are safe and effective when provided by a trained, experienced provider.

PURPOSE
Sleeve gastrectomy is one of the most popular bariatric procedures performed. A complication of this surgery is sleeve stenosis, causing significant morbidity and the need for corrective intervention. Endoscopic treatment using pneumatic dilation has evolved as an effective, and minimally invasive, technique to successfully treat this complication. Here we report our experience with endoscopic management of sleeve stenosis at a tertiary bariatric center.
MATERIAL AND METHODS
We identified all patients that underwent endoscopic management of sleeve stenosis at a tertiary bariatric center from 2010. We reviewed patient demographics, operative data, interval to endoscopic treatment, and outcomes of pneumatic dilations.
RESULTS
Sixty seven patients underwent 130 endoscopic dilations. The majority of these patients were female (71%), and at the time of sleeve gastrectomy average age was 43.3 years (range 18-68 years) and average BMI was 41.5 kg/m (range 31-63 kg/m). The time interval to first endoscopic procedure was 7.2 months (range 0.75-53 months), with an average of 2 procedures per patient. During the follow-up period, the success rate of endoscopic dilatation was 76.1%, while the remaining 16 patients underwent conversion to gastric bypass. Two patients underwent emergency conversion to gastric bypass for sleeve perforation during the procedure (1.5%). There was a modest weight gain of 3 kg (4.2% total body weight) after sleeve dilatation.
CONCLUSIONS
Endoscopic management of sleeve stenosis is safe and effective, with a success rate of over 75%. During endoscopic management, there was a 1.5% risk of sleeve perforation requiring emergency surgery. Mild weight regain occurred following endoscopic sleeve dilation.

Endoscopic balloon dilatation is an established treatment for benign gastrointestinal strictures. In order to dilatate safely, it is necessary to dilatate gradually and preferably under direct endoscopic visualization. However, it is currently difficult to achieve dilatation widths of 20-30 mm with commercial products and of over 30-mm with endoscopic visualization. Therefore, a safe and innovative application technique is needed for patients who need these 20-mm or greater dilatation widths. We have developed two methods that enable more than 20-mm dilatation under direct visualization. (i) Single-barrel method: an endoscopic balloon dilatation catheter was fixed with grasping forceps at the tip of the endoscope and carried into the stomach. The balloon catheter was released from the endoscope to create a retroflexed view. The endoscope and balloon were positioned adjacent to each other at the gastric cardia. The balloon was inflated gradually and the esophagogastric junction was dilatated under direct visualization. (ii) Double-barrel method: the same procedure was repeated with two balloons. Theoretically, we achieved a dilatation of >30-mm in diameter. These modified methods may be helpful for esophagogastric junction strictures, such as esophageal achalasia (serving as an initial endoscopic balloon dilatation prior to using a 30-mm achalasia balloon), or for functional strictures after Nissen fundoplication. In conclusion, our simple, modified method enables safe and gradual dilatation under direct endoscopic visualization. Additionally, combination of the sizes of one or two balloons can achieve various widths of dilatation.

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.
