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.

Crohn's disease (CD) is a pan-intestinal disease of the gastrointestinal tract characterized by inflammatory, penetrating, and fibrostenotic phenotypes. Fibrostenotic stricture formation, without inflammatory or penetrating disease, is a common complication in CD, primarily affecting the small intestine and leading to small bowel obstruction. Because there is no medical therapy that prevents or reverses stricturing disease, endoscopic and surgical treatments are the mainstays of treatment, indicated to palliate symptoms and treat the complications. Endoscopic approaches include dilation, stricturotomy, and endoscopic stenting. Surgical options include resection, intestinal bypass, and various strictureplasty techniques. In this article, we will focus on the treatment of stricturing CD: specifically, the considerations important in choosing between different treatment options and technical tips to deal with complicated disease.

Review
The assessment of labor progress is germane to every woman in labor. Two labor disorders-arrest of dilation and arrest of descent-are the primary indications for surgery in close to 50% of all intrapartum cesarean deliveries and are often contributing indications for cesarean deliveries for fetal heart rate abnormalities. Beginning in 1954, the assessment of labor progress was transformed by Friedman. He published a series of seminal works describing the relationship between cervical dilation, station of the presenting part, and time. He proposed nomenclature for the classification of labor disorders. Generations of obstetricians used this terminology and normal labor curves to determine expected rates of dilation and fetal descent and to decide when intervention was required. The analysis of labor progress presents many mathematical challenges. Clinical measurements of dilation and station are imprecise and prone to variation, especially for inexperienced observers. Many interrelated factors influence how the cervix dilates and how the fetus descends. There is substantial variability in when data collection begins and in the frequency of examinations. Statistical methods to account for these issues have advanced considerably in recent decades. In parallel, there is growing recognition among clinicians of the limitations of using time alone to assess progress in cervical dilation in labor. There is wide variation in the patterns of dilation over time and most labors do not follow an average dilation curve. Reliable assessment of labor progression is important because uncertainty leads to both over-use and under-use of cesarean delivery and neither of these extremes are desirable. This review traces the evolution of labor curves, describes how limitations are being addressed to reduce uncertainty and to improve the assessment of labor progression using modern statistical techniques and multi-dimensional data, and discusses the implications for obstetrical practice.

OBJECTIVE
To compare, in terms of anatomical, functional, and sexual aspects, two types of treatment for women with vaginal agenesis: progressive dilation or surgical neovaginoplasty.
METHODS
Women with vaginal agenesis underwent either dilation treatment using the Frank method or surgical treatment using the modified Abbé-McIndoe technique with oxidized cellulose. Patients were evaluated 3-6 months after treatment for a follow-up including medical history, physical examination, general satisfaction, clinical aspect of the vagina, Female Sexual Function Index, and three-dimensional pelvic floor ultrasound.
RESULTS
In total, 20 women with vaginal agenesis were included in the present study; nine in the dilation group and 11 in the surgical group. A comparison between the groups (vaginal dilation and surgical neovaginoplasty) showed efficacy in neovagina formation after both treatments, with a statistically significant difference between the pre- and post-treatment periods (P value pre- × post-dilation group <0.0001 and P value pre- × post-surgical group <0.0001). There were no statistical differences in total vaginal length measurements (P value post-dilation × post-surgical = 0.09) or Female Sexual Function Index scores (P = 0.72) after both treatments.
CONCLUSION
Both treatments had satisfactory efficacy and positive outcomes for patients with vaginal agenesis concerning anatomical, functional, and sexual aspects, with minimum complications in the surgical group. Dilation treatment can remain the first-line therapy.

Meta-Analysis Review
OBJECTIVES
Esophageal dilation (ED) may be performed in the office under local anesthesia or in a procedure/operating room under general anesthesia or intravenous (IV) sedation. However, indications for type of anesthesia during these procedures have not been established. The purpose of this review is to assess outcomes of esophageal dilation performed using different types of anesthesia to assess the safety of office-based techniques.
METHODS
We conducted a systematic review and meta-analysis comparing the outcomes of anesthesia techniques for ED in adults. Exclusion criteria included reviews, small case series, use of stents, diagnoses with high morbidity, and rare diseases. A comprehensive literature search of the PubMed, CINAHL, and EMBASE databases was performed for articles relating to esophageal dilation.
RESULTS
876 papers were identified of which 164 full text studies were assessed and 25 were included in the analysis using the PRISMA guidelines. Data regarding demographics, dilation technique, and adverse events were extracted. The DerSimonian-Laird random-effect models with inverse-variance weighting were fit to estimate the combined effects. There were no statistically significant differences among mortality, perforation, or bleeding based on anesthetic.
CONCLUSIONS
With office-based procedures gaining popularity in laryngology, there is a need to profile their safety. Office-based ED appears to have equivalent safety to general and IV sedation, although further research is necessary to define indications favoring office-based techniques.

Retinal microvascular calibre has been proposed as a predictor of cardiac events. Surgery is a major stimulus for inflammation which potentially affects small vessel calibre. This study examined the effects of surgery on retinal, and thus systemic, small vessel size, and the potentially confounding effect of surgery when retinal vessel calibre is used to predict cardiac risk in hospital patients. Consecutive participants were recruited from a preoperative assessment clinic at a teaching hospital. They provided demographic and clinical details, and underwent retinal imaging before and again, within 3 days after surgery, with a non-mydriatic retinal camera. Images were graded for vessel calibre using semi-automated software based on the Parr-Hubbard formula with Knudtson's modification (IVAN, U Wisconsin). Differences were examined using Fisher's exact test or a paired t-test, and calibre determinants identified from univariate and multiple linear regression analysis (STATA version 11.2). Sixty-eight participants (23 men, 34%) with a mean age of 55 ± 14.5 years, were recruited. Fourteen (21%) underwent a laparotomy which was considered major surgery and 54 (79%) had Other surgery. Mean C-reactive protein (CRP) levels increased post-operatively from 7.8 ± 20.2 mg/L to 43.9 ± 55.1 mg/L (p < 0.01), and mean serum albumin decreased from 38.9 ± 4.4 g/L to 33.9 ± 5.5 g/L (p < 0.01). Mean central retinal arteriole and venular equivalent calibre (CRAE, CRVE) increased post-operatively (142.4 ± 13.3 µm to 146.4 ± 13.0 µm, p < 0.01 and 213.1 ± 16.8 µm to 217.9 ± 18.3 µm, p < 0.01, respectively). The systemic microvasculature dilates post-operatively possibly secondary to inflammation and endothelial dysfunction. These changes were present within 3 days of surgery and may confound the use of small vessel calibre to predict cardiac risk in surgical inpatients. Microvascular dilatation in response to other inflammatory stimuli such as pneumonia is a known potential confounder in hospital patients.

The Turkish Journal of Gastroenterology... Apr 2023The aim of the study was to share the effectiveness of pneumatic dilation in geriatric achalasia patients.
BACKGROUND
The aim of the study was to share the effectiveness of pneumatic dilation in geriatric achalasia patients.
METHODS
Achalasia patients over the age of 65 and those under the age of 65 as the control group who received pneumatic dilation as the first-line treatment were evaluated in the study.
RESULTS
The average age of geriatric patients was 72.5 ± 55.92 years (65-90), with 50.3% of them being male. Follow-up was conducted for a mean of 64.52 ± 38.73 months. While pneumatic dilation was successful in 98.6% (141/143) of geriatric patients, it was also successful in 94% (141/150) of non-geriatric patients. Remission after single balloon dilatation was observed in 81.8% of geriatric patients, while it was observed in only 52.7% of non-geriatric patients (P = .000). When comparing remission after single dilatation and multiple dilatations, it was observed that geriatric patients who achieved remission after multiple balloon dilatation had higher lower esophageal sphincter pressure and Eckardt scores at the diagnosis and higher lower esophageal sphincter pressure and esophageal body resting pressures after the first balloon dilatation.
CONCLUSIONS
The proportion of elders in the world population is increasing daily and this disease has been known to disproportionately afflict this group. Although surgical treatments, in particular per-oral endoscopic myotomy, have recently gained popularity as therapies for achalasia, pneumatic dilation remains the most commonly used in geriatric patients.

Comparative Study
BACKGROUND
The aim of this study was to compare four renal access techniques in percutaneous nephrolithotomy (PCNL).
METHODS
A total of 437 patients who underwent PCNL at our center from January 2015 to December 2019 were included in the analysis. Telescopic metallic coaxial dilation (TMD) was used in 146 patients, single step balloon dilation (BD) in 98 patients, one-shot dilation with 30F Amplatz (OS 30F) in 106 patients, and one-shot dilation with 16F Amplatz (OS 16F) in 87 patients. Primary endpoints were perioperative outcomes and complications of the procedures.
RESULTS
Similar baseline characteristics were observed in the four groups. Fluoroscopy time was significantly shorter in OS 30F and OS 16F groups (P<0.0001). The drop in hemoglobin level was not significantly different between TMD and BD groups, but it was significantly lower in OS 16F group versus the OS 30F group and lower in OS 30F group versus the BD Group (P<0.0001). Despite this, the rate of blood transfusion was similar across groups (P=0.837). Moreover, a smaller tract was associated with reduced postoperative morbidity including time to nephrostomy removal (P=0.001), hospital stay (P<0.0001), VAS scale (P<0.0001). There were no significant differences in postoperative complications (P=0.683), and Clavien-Dindo grade ≥3 complication rates (P=0.486) among the groups. Stone-free rates and number of auxiliary procedures required to achieve stone-free status were also similar among all groups (P=0.964 and 0.988, respectively). Multinomial logistic regression analysis showed that BMI (P=0.002), stone size (P=0.002) and previous PCNL (P=0.038) were predictive factors associated with the choice of OS 16 approach.
CONCLUSIONS
Different dilation methods are equally effective and safe to use in a PCNL procedure for kidney stone treatment, allowing similar stone free rates and risk of complications. The OS dilation techniques seem to allow a shorter X-ray exposure time, which might be beneficial for both patients and operators. The use of a 16 F dilator can reduce the postoperative morbidity. Risk of sepsis should be always kept in mind.
