The Efficacy and Safety of Endoscopic Balloon Dilatation in the Treatment of Functional Post-Sleeve-Gastrectomy Stenosis.

Background and Objectives: 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. Patients and Methods: 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. Results: 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. Conclusions: Endoscopic balloon dilatation is an effective and safe minimally invasive procedure in the management of functional post-sleeve-gastrectomy stenosis.

Large-Caliber Empiric Esophageal Dilation Results in Sustained Improvement for Selected Patients With Nonobstructive Dysphagia.

INTRODUCTION: Empiric esophageal dilation (EED) remains a controversial practice for managing nonobstructive dysphagia (NOD) secondary to concerns about safety and efficacy. We examine symptom response, presence of tissue disruption, and adverse events (AEs) after EED. METHODS: We examined large-caliber bougie EED for NOD at 2 tertiary referral centers: retrospectively evaluating for AEs. Esophageal manometry diagnoses were also reviewed. We then prospectively assessed EED's efficacy using the NIH Patient-Reported Outcomes Measurement Information System disrupted swallowing questionnaire to assess dysphagia at baseline, 1, 3, and 6 months after EED. Treatment success was defined by improvement in patient-reported outcome scores. RESULTS: AE rate for large-caliber dilation in the retrospective cohort of 180 patients undergoing EED for NOD was low (0.5% perforations, managed conservatively). Visible tissue disruption occurred in 18% of patients, with 47% occurring in the proximal esophagus. Obstructive motility disorders were found more frequently in patients with tissue disruption compared with those without (44% vs 14%, P = 0.05). The primary outcome, the mean disrupted swallowing T -score was 60.1 ± 9.1 at baseline, 56.1 ± 9.5 at 1 month ( P = 0.03), 57 ± 9.6 at 3 months ( P = 0.10), and 56 ± 10 at 6 months ( P = 0.02) (higher scores note more symptoms). EED resulted in a significant and durable improvement in dysphagia and specifically solid food dysphagia among patients with tissue disruption. DISCUSSION: EED is safe in solid food NOD and particularly effective when tissue disruption occurs. EED tissue disruption in NOD does not preclude esophageal dysmotility.

Safety of Percutaneous Dilatational Tracheostomy in Critically Ill Patients with Liver Cirrhosis.

INTRODUCTION: Percutaneous dilatational tracheostomy (PDT) is a safe and cost-effective alternative to surgical tracheostomy. Cirrhotic patients often require ICU admission and prolonged mechanical ventilation. Patients with liver cirrhosis (LC) are known to have coagulopathy and relatively safe and simple procedures such as tracheostomy may be associated with high complication rates, specifically high bleeding rates. Current guidelines are unable to make a specific recommendation on the safety of PDT among cirrhotic patients. We aimed to evaluate the safety of PDT in critically ill patients with LC. METHODS: A retrospective chart review identified critically ill patients who underwent PDT between January 2012 and March 2023. The study group was defined as all patients with a diagnosis of LC. The primary outcome was early (7-day) bleeding, categorized as minor or major. Secondary outcomes were PDT-related and 30-day all-cause mortality. Propensity score matching was performed to adjust the imbalances between the groups. RESULTS: A total of 1,628 were included in the analysis. Thirty-three of them (2.0%) had LC. In the LC group, only 1 patient (3.0%, 95% CI: 0.0-15.8%) developed early bleeding. Intra-operative, early, late bleeding, and PDT-related mortality rates did not differ significantly between those with LC and those without. CONCLUSION: This retrospective cohort study indicates that PDT can be safely performed in critically ill cirrhotic patients, without significantly increasing the risk of bleeding complications.

Endoscopic Dilatation with Ultrathin Endoscope Assisted Method for Esophageal and Pyloric Stricture related Corrosive Injury: 4 Years Case Series Study.

Corrosive injuries (CI) become medical problems related complications include esophageal, pyloric stricture and squamous cell carcinoma, physical and quality of life. Endoscopic (ED) dilatation is primary therapy. The ultrathin endoscope-assisted method is potentially safe and useful in avoiding technical failure. Describe clinical outcomes of ED ED-related CI including successful, refractory, recurrent, and complications-related procedures. Case series study of esophageal and/or pyloric stricture patients after CI who underwent dilatation at Soetomo General Hospital (July 2018 - July 2022). One - biweekly ED using Through The Scope (TTS) balloon or Savary Bougie dilator. The target diameter is 14mm. Fifteen patients with stricture-related CI. Eleven patients underwent ED with a total of 73 procedures. Mean age 31,45 years, predominantly male patients (6), suicide attempt (7), acid agent (9), located at esophagus (3), pylorus (3), or both (5). Number of esophageal dilatation to achieve the target of 14 mm was 1-2 and 2-15 procedures for simple and complex stricture. Five esophageal strictures were successfully dilated but 2 patients were recurrent and 3 cases were refractory to ED. Pyloric dilatation resulted in a lower success rate. Recurrent and refractory cases were 5 and 3 patients respectively. ED with ultrathin endoscope method is useful for traversing guidewire during ED. Ongoing inflammation and fibrosis were linked to recurrent and refractory stricture.

Safety of skipping the tract dilation step for EUS-guided biliary drainage in patients with unresectable malignant biliary obstruction (with video).

BACKGROUND: Thin delivery system stents can be inserted directly without the need for a tract dilation step and are expected to reduce bile leakage during endoscopic ultrasound-guided biliary drainage (EUS-BD). The present study retrospectively compared the safety and efficacy of EUS-BD using a thin metal stent (< 7.5 Fr) with those of EUS-BD using a conventional stent (≥ 7.5 Fr). METHODS: The present study enrolled 112 patients who underwent EUS-BD using metal stents for unresectable malignant biliary obstruction between April 2016 and July 2022. The primary endpoint was the rate of adverse events (AEs). The secondary endpoints were clinical success rate, procedure time, procedure success rate in the absence of the tract dilation step, recurrent biliary obstruction rate, time to biliary obstruction, and overall survival. Risk factors associated with early AEs were also evaluated. RESULTS: The rate of early AEs was significantly lower (12% vs. 35%, P = 0.013) and the procedure success without the tract dilation step was significantly higher (82% vs. 33%, P < 0.001) in the thin than in the conventional delivery system stent group. None of the other secondary endpoints differed significantly between the two groups. Multivariate analysis showed that employing the tract dilation step during EUS-BD was a significant independent risk factor for early AEs (skipping vs. employing; HR, 9.66; 95% CI, 1.13-83.0, P = 0.028). CONCLUSION: Employing the tract dilation step during EUS-BD was a significant risk factor for early AEs. Metal stents with a delivery diameter < 7.5 Fr can be inserted directly without the tract dilation step, resulting in lower early AE rates.

[Balloon dilation as an alternative to tracheotomy for acquired subglottic stenosis in children of the first year of life]. / Ballonnaya dilatatsiya kak al'ternativa trakheotomii pri priobretennom podskladkovom rubtsovom stenoze u detei pervogo goda zhizni.

OBJECTIVE: To study the efficacy and safety of balloon dilation as the first choice method in the treatment of children of the first year of life with acquired subglottic stenosis. MATERIAL AND METHODS: A retrospective analysis of the treatment of 25 patients aged 27 days to 11 months of life (average age 5.3±3.76 months) with subglottic stenosis caused by prolonged intubation, in whom balloon dilation was the first method of treatment. Grade III Cotton-Myer stenosis was preoperatively detected in 22 children, the remaining 3 had grade II stenosis. RESULTS: The success rate of balloon dilation was 100%; tracheotomy was not required in any case, the absence of stenosis during a follow-up examination in the catamnesis was recorded in 14 (56%) children, the remaining 11 (44%) had grade 0-I stenosis and did not cause respiratory disorders. In 1 child (1.5 years old), a subglottic cyst was removed after balloon dilation. One dilation was required in 18 (72%) children, two - in 5 (20%), three and four - respectively for 1 patient. If additional intervention was necessary, the operation was repeated 10 days - 3 months after the previous one. There were no postoperative complications. CONCLUSION: Balloon dilation is a highly effective and safe alternative to traditional surgical interventions for acquired subglottic stenosis in children of the first year of life and can be recommended as a method of first choice.

Late Pulmonary Autograft Dilation: Can We Make a Good Operation Great? The Tailored Approach.

While it is the main viable option in the growing child and young adult, the Ross procedure has expanded its applicability to older patients, for whom long-term results are equivalent, if not superior, to prosthetic aortic valve replacement. Strategies aiming at mitigating long-term autograft failure from root enlargement and valve regurgitation have led some to advocate for root reinforcement with prosthetic graft material. On the contrary, we will discuss herein the rationale for a tailored approach to the Ross procedure; this strategy is aimed at maintaining the natural physiology and interplay between the various autograft components. Several technical maneuvers, including careful matching of aortic and autograft annuli and sino-tubular junction as well as external support by autologous aortic tissue maintain these physiologic relationships and the viability of the autograft, and could translate in a lower need for late reintervention because of dilation and/or valve regurgitation.

Balloon dilatation for congenital esophageal stenosis associated with esophageal atresia.

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.

Effects of vaginal dilation therapy on vaginal length, vaginal stenosis, vaginal elasticity and sexual function of cervical cancer survivors.

BACKGROUND: Cervical cancer survivors can experience vaginal length shortening, vaginal stenosis, vaginal elasticity deterioration, sexual frequency reduction and sexual dysfunction. This prospective, uncontrolled, monocentric clinical interventional study aimed to evaluate the effect of vaginal dilation therapy on vaginal condition and sexual function of cervical cancer survivors who had not received timely vaginal dilation. METHODS: A total of 139 patients completed the study. They received 6 months of vaginal dilation therapy. We evaluated their vaginal elasticity, vaginal diameter, vaginal length and sexual function before and after vaginal dilation therapy. Their vaginal conditions were evaluated by customised vaginal moulds, and the sexual function was assessed by female sexual function index. The SPSS 25 software was used to analyse all the data. RESULTS: Age, vaginal diameter and sexual intercourse frequency before diagnosis were significantly associated with female sexual dysfunction of the patients after cancer treatment. Vaginal dilation therapy improved vaginal stenosis, vaginal length and sexual function in all the patients; however, the vaginal elasticity and incidence of sexual dysfunction did not improve significantly. Sexual intercourse frequency before diagnosis, vaginal elasticity, time interval from last treatment and treatment modalities were significantly associated with the change in female sexual function index score before and after vaginal dilation therapy. Patients with a time interval from the last treatment less than 24 months or those who had moderate or good vaginal elasticity, benefitted more from vaginal dilatation therapy. CONCLUSIONS: Cervical cancer survivors who had not received timely vaginal dilation still benefitted from vaginal dilation therapy, irrespective of the treatment methods they received. Moreover, vaginal dilation therapy should be performed as early as possible after cervical cancer treatment.

Cervical cancer survivors can experience vaginal condition deterioration and sexual dysfunction after treatment. Vaginal dilation can help improve vaginal stenosis, vaginal length and sexual function of these patients. However, some medical institutions in China do not provide timely vaginal dilation for this population. This study aimed to explore whether vaginal dilation was still effective for cervical cancer survivors who had not received timely vaginal dilation. The results showed that these patients still benefitted from vaginal dilation, irrespective of the treatment methods they received. Patients with a time interval from the last treatment less than 24 months or those who had moderate or good vaginal elasticity, benefitted more from vaginal dilation. The findings of the study is an indication to developing countries that more attention should be given to sexual issue of cervical cancer survivors in clinical practice, and vaginal dilation therapy should be performed promptly after treatment.

Robotic surgery in the management of synchronous esophageal and gastric perforation after endoscopic dilation.

Upper gastrointestinal perforation is a feared complication of diagnostic and therapeutic endoscopy, with an incidence of perforation between 0.3% and 5%. Even though is rare, the mortality rate can be as high as 40%. Currently, there is no consensus on the best therapeutic strategy and it usually depends on patient stability, the extent of perforation, time to diagnosis, surgeon experience and available resourcesWe present a case of a patient who presented to our institution to undergo an ambulatory oesophageal dilation. After dilation, the patient developed two full-thickness gastric perforations and a full-thickness oesophageal perforation without haemodynamic instability. All perforations were diagnosed and treated with a combination of intraoperative endoscopy and robotic surgery with excellent outcomes.We demonstrate that a robotic approach combined with intraoperative diagnostic endoscopy is a safe and feasible treatment option for esophageal and gastric perforations in a stable patient without large extraluminal contamination.

Stability of infundibular dilatations: a single center follow-up study and systematic review of the literature.

PURPOSE: Although infundibular dilatations (IDs) have been thought to be benign anatomical variants, case reports suggest that they can grow and rupture. The aim of this study was to determine whether IDs have a tendency to grow or rupture. METHODS: The study population was collected from the Tampere University Hospital (TAUH) Aneurysm Database. The presence of IDs was screened from the medical records and imaging studies of 356 intracranial aneurysm patients left to follow-up from 2005 to 2020. The imaging studies were reviewed to confirm the IDs, and their clinical course. Finally, we performed a systematic review of published cases of ID leading to aneurysmatic rupture from PubMed. RESULTS: We found 97 typical IDs in 83 patients and 9 preaneurysmal lesions resembling ID in 9 patients. Out of the typical cone-shaped IDs, none grew or ruptured in a total follow-up of 409 patient-years. One preaneurysmal lesion ruptured during a follow-up: this lesion had components of both infundibular dilatation and aneurysm at the beginning of follow-up. In the systematic literature search, we found 20 cases of aneurysmatic SAHs originating from an ID. Of those, only 7 had imaging available prerupture. All 7 IDs were typically cone-shaped, but a branching vessel originating from the apex of ID was only seen in 4/7. CONCLUSION: Typical infundibular dilatations seem to be benign anatomical variants that are stable and, thus, do not need prophylactic treatment or imaging follow-up. Likely, the SAHs reported from IDs were actually caused by misdiagnosed preaneurysmal lesions.

Prediction of spontaneous preterm birth in women with previous full dilatation cesarean delivery.

BACKGROUND: A previous term (≥37 weeks' gestation), full-dilatation cesarean delivery is associated with an increased risk for a subsequent spontaneous preterm birth. The mechanism is unknown. We hypothesized that the cesarean delivery scar characteristics and scar position relative to the internal cervical os may compromise cervical function, thereby leading to shortening of the cervical length and spontaneous preterm birth. OBJECTIVE: This study aimed to determine the relationship of cesarean delivery scar characteristics and position, assessed by transvaginal ultrasound, in pregnant women with previous full-dilatation cesarean delivery with the risk of shortening cervical length and spontaneous preterm birth. STUDY DESIGN: This was a single-center, prospective cohort study of singleton pregnant women (14 to 24 weeks' gestation) with a previous term full-dilatation cesarean delivery who attended a high-risk preterm birth surveillance clinic (2017-2021). Women underwent transvaginal ultrasound assessment of cervical length, cesarean delivery scar distance relative to the internal cervical os, and scar niche parameters using a reproducible transvaginal ultrasound technique. Spontaneous preterm birth prophylactic interventions (vaginal cervical cerclage or vaginal progesterone) were offered for short cervical length (≤25 mm) and to women with a history of spontaneous preterm birth or late miscarriage after full-dilatation cesarean delivery. The primary outcome was spontaneous preterm birth; secondary outcomes included short cervical length and a need for prophylactic interventions. A multivariable logistic regression analysis was used to develop multiparameter models that combined cesarean delivery scar parameters, cervical length, history of full-dilatation cesarean delivery, and maternal characteristics. The predictive performance of models was examined using the area under the receiver operating characteristics curve and the detection rate at various fixed false positive rates. The optimal cutoff for cesarean delivery scar distance to best predict a short cervical length and spontaneous preterm birth was analyzed. RESULTS: Cesarean delivery scars were visualized in 90.5% (220/243) of the included women. The spontaneous preterm birth rate was 4.1% (10/243), and 12.8% (31/243) of women developed a short cervical length. A history- (n=4) or ultrasound-indicated (n=19) cervical cerclage was performed in 23 of 243 (9.5%) women; among those, 2 (8.7%) spontaneously delivered prematurely. A multiparameter model based on absolute scar distance from the internal os best predicted spontaneous preterm birth (area under the receiver operating characteristics curve, 0.73; 95% confidence interval, 0.57-0.89; detection rate of 60% for a fixed 25% false positive rate). Models based on the relative anatomic position of the cesarean delivery scar to the internal os and the cesarean delivery scar position with niche parameters (length, depth, and width) best predicted the development of a short cervical length (area under the receiver operating characteristics curve, 0.79 [95% confidence interval, 0.71-0.87]; and 0.81 [95% confidence interval, 0.73-0.89], respectively; detection rate of 73% at a fixed 25% false positive rate). Spontaneous preterm birth was significantly more likely when the cesarean delivery scar was <5.0 mm above or below the internal os (adjusted odds ratio, 6.87; 95% confidence interval, 1.34-58; P =.035). CONCLUSION: In pregnancies following a full-dilatation cesarean delivery, cesarean delivery scar characteristics and distance from the internal os identified women who were at risk for spontaneous preterm birth and developing short cervical length. Overall, the spontaneous preterm birth rate was low, but it was significantly increased among women with a scar located <5.0 mm above or below the internal cervical os. Shortening of cervical length was strongly associated with a low scar position. Our novel findings indicate that a low cesarean delivery scar can compromise the functional integrity of the internal cervical os, leading to cervical shortening and/or spontaneous preterm birth. Assessment of the cesarean delivery scar characteristics and position seem to have use in preterm birth clinical surveillance among women with a previous, full-dilatation cesarean delivery and could better identify women who would benefit from prophylactic interventions.

Comprehensive review and update of stricturing Crohn's disease.

Up to 50% of patients with Crohn's disease develop a stricture within 10 years of diagnosis. Crohn's strictures can compose of inflammation, fibrosis or smooth muscle expansion and usually a combination of these. There have been numerous new developments in imaging modalities in determining the composition of Crohn's strictures. Magnetic resonance imaging remains the best upfront imaging modality to characterize Crohn's strictures. Gastrointestinal ultrasound (GIUS) has an increasing role in clinical practice, particularly for monitoring stricture response as a treat-to-target tool. Novel imaging techniques to differentiate between fibrosis and inflammatory strictures have been developed including contrast-enhanced GIUS, strain or shear wave elastography with GIUS and multiple new magnetic resonance imaging (MRI) protocols, including diffusion weighted, delayed contrast enhancement and magnetization transfer MR protocols. However, these techniques require further validation and standardization. Regarding therapeutics, anti-tumor necrosis agents with a treat-to-target strategy have the highest quality evidence in treating strictures and can lead to stricture regression in some cases. Endoscopic balloon dilatation remains a mainstay in the treatment algorithm of treating predominantly fibrostenotic Crohn's strictures, particularly those which are symptomatic, < 5 cm in length and not causing prestenotic dilatation. Endoscopic balloon dilatation has greater effectiveness in anastomotic strictures. Surgery remains an important treatment option in Crohn's strictures, with segmental resection and stricturoplasty having their own advantages and disadvantages. Kono-S anastomosis may be superior to conventional anastomosis for endoscopic recurrence; however, further high-quality studies are required to confirm this. Using risk stratification models such as the BACARDI risk model is important to guide management decisions between a medical and surgical approach. Early post-operative medical prophylaxis with an advanced therapy is an important consideration to prevent disease recurrence. This review expands on the above topics, highlights research gaps and provides a suggested investigation and management pathway in stricturing Crohn's disease.

Comparison of endoscopic balloon dilation and surgery for duodenal stricture in patients with Crohn's disease.

BACKGROUND: Few studies have compared endoscopic balloon dilation (EBD) and surgery in the treatment of duodenal stricture in patients with Crohn's disease (CD). METHODS: We performed a retrospective study to compare the efficacy and safety among patients with CD-associated duodenal stricture treated with EBD or surgery from October 2013 to December 2021. Univariate and multivariate analyses were performed to evaluate factors associated with recurrence-free or surgery-free survival. RESULTS: A total of 48 eligible patients were included, including 30 patients treated with EBD only and 18 patients treated with surgery. Patients treated with surgery experienced more symptomatic improvement (100% vs. 63.33%, p = 0.003) and significantly longer recurrence-free survival (6.31 [IQR: 3.00-8.39] years vs. 2.96 [IQR: 1.06-5.42] years, p = 0.01) but suffered more postprocedural adverse events (16.67% vs. 0.74% per procedure, p = 0.001). In patients initially treated with EBD (n = 41), a total of 11 (26.83%) required subsequent surgical intervention. Younger age at CD diagnosis (HR = 0.90, 95% CI: 0.81-1.00, p = 0.04) was associated with a higher risk for subsequent surgery. CONCLUSIONS: Surgery for CD-associated duodenal strictures was associated with a longer recurrence-free survival. EBD was safe and effective with minimal postprocedural adverse events but led to a high frequency of recurrence.

The Safety of Dilation of Ileoanal Strictures With Mechanical or Balloon Dilation Is Similar Among Patients After Ileal Pouch-Anal Anastomosis.

BACKGROUND: Anastomotic strictures occur in up to 38% of patients after ileal pouch-anal anastomosis (IPAA). We sought to compare the safety, effectiveness, and durability of mechanical dilation using a Hegar dilator to endoscopic through-the-scope balloon dilation (EBD) among IPAA patients with a rectal or ileoanal anastomotic stricture. METHODS: We identified adult patients with an IPAA for ulcerative colitis (UC) who underwent a pouchoscopy between January 1, 2015, and December 31, 2019, at a single institution. We compared the effectiveness (median maximum diameter of dilation [MMD]), safety, and durability of mechanical and balloon dilation using standard statistical comparisons. RESULTS: A total 74 patients had a stricture at the ileoanal anastomosis and underwent at least 1 mechanical or balloon dilation. The MMD with mechanical dilation was 19 (interquartile range [IQR], 18-20) mm for the first dilation and 20 (IQR, 18-20) mm for the second and third dilations. With balloon dilation, the MMD was 12 (IQR, 12-18) mm for the first dilation, 15 (IQR, 12-16.5) mm for the second dilation, and 18 (IQR, 15-18.5) mm for the third dilation. Patients undergoing mechanical dilation experienced a longer duration to second dilation (median 191 days vs 53 days: P < .001), with no difference in complications such as bleeding or perforation noted. CONCLUSIONS: Among patients with ileoanal and rectal strictures, mechanical and balloon approaches to dilation demonstrated similar safety profiles and effectiveness. Mechanical dilation with Hegar dilators appears to be an effective and safe approach to the treatment of distal strictures after IPAA.

Distal strictures are common in patients after ileal pouch­anal anastomosis. We demonstrated that both mechanical dilation with Hegar dilators and balloon dilation are safe and effective approaches to rectal or ileoanal strictures after ileal pouch­anal anastomosis.

10-year follow-up results of the European Achalasia Trial: a multicentre randomised controlled trial comparing pneumatic dilation with laparoscopic Heller myotomy.

OBJECTIVE: As achalasia is a chronic disorder, long-term follow-up data comparing different treatments are essential to select optimal clinical management. Here, we report on the 10-year follow-up of the European Achalasia Trial comparing endoscopic pneumodilation (PD) with laparoscopic Heller myotomy (LHM). DESIGN: A total of 201 newly diagnosed patients with achalasia were randomised to either a series of PDs (n=96) or LHM (n=105). Patients completed symptom (Eckardt score) and quality-of-life questionnaires, underwent functional tests and upper endoscopy. Primary outcome was therapeutic success defined as Eckardt score <3 at yearly follow-up. Secondary outcomes were the need for retreatment, lower oesophageal sphincter pressure, oesophageal emptying, gastro-oesophageal reflux and the rate of complications. RESULTS: After 10 years of follow-up, LHM (n=40) and PD (n=36) were equally effective in both the full analysis set (74% vs 74%, p=0.84) and the per protocol set (74% vs 86%, respectively, p=0.07). Subgroup analysis revealed that PD was superior to LHM for type 2 achalasia (p=0.03) while there was a trend, although not significant (p=0.05), that LHM performed better for type 3 achalasia. Barium column height after 5 min at timed barium oesophagram was significantly higher for patients treated with PD compared with LHM, while other parameters, including gastro-oesophageal reflux, were not different. CONCLUSIONS: PD and LHM are equally effective even after 10 years of follow-up with limited risk to develop gastro-oesophageal reflux. Based on these data, we conclude that PD and LHM can both be proposed as initial treatment of achalasia.

Effect of open surgical and percutaneous dilatational tracheostomy on postoperative wound complications in patients: A meta-analysis.

Tracheostomy is one of the most common operations. The two main methods of tracheostomy are open surgical tracheostomy (OST) and percutaneous dilatational tracheostomy (PDT). In critical cases, the combination of these two approaches is especially crucial, with the possibility of successful outcomes and low complications. Thus, the purpose of this system is to analyse the effects of both methods on the outcome of postoperative wound. In this research, we performed a systematic review of Cochrane Library, PubMed, Web of Science and Embase, to determine all randomized controlled trials (RCTs) that are comparable in terms of postoperative injury outcomes. Eleven RCTs were found after screening. This study will take the necessary data from the selected trials and evaluate the documentation for RCTs. PDT was associated with a lower incidence of infection at the wound site than OST (OR, 4.46; 95% CI: 2.84-7.02 p < 0.0001), and PDT decreased blood loss (OR, 2.88; 95% CI: 1.62-5.12 p = 0.0003). But the operation time did not differ significantly in both PDT to OST (MD, 4.65; 95% CI: -1.19-10.48 p = 0.12). The meta-analyses will assist physicians in selecting the best operative procedure for critical cases of tracheostomy. These data can serve as guidelines for clinical management and in the design of future randomized, controlled studies.

The use of adjunctive mechanical dilation at the time of induction termination and adverse health outcomes: a systematic review.

OBJECTIVE: This study aimed to assess if the use of mechanical dilation at the time of induction termination is associated with changes in the time from initiation of labor to expulsion of the fetus (induction-to-expulsion interval) and with the frequency of health complications when compared with medication management alone. DATA SOURCES: PubMed, CINAHAL, Scopus, and the Cochrane Central Register of Controlled Trials were queried from January 2000 to May 2023. STUDY ELIGIBILITY CRITERIA: We included randomized controlled trials of individuals who were assigned to undergo mechanical dilation (ie, laminaria, Dilapan-S, and intracervical Foley balloon catheter) in combination with the use of medication and compared it with the outcomes of medication use (eg, prostaglandins, antiprogestins, oxytocin) alone. METHODS: The primary outcome was the induction-to-expulsion interval. The secondary outcomes were the incidence of clinical chorioamnionitis, sepsis, hemorrhage, the need for blood transfusion and uterotonics, cervical laceration, the need for adjunctive procedures (eg, dilation and curettage), failed induction termination, uterine rupture, intensive care unit admission, or death. Assessment of bias was performed using the Cochrane Risk of Bias tool. A subgroup analysis was performed among studies deemed to be at low risk of bias. RESULTS: Of 864 abstracts identified, 11 met the inclusion criteria. Five studies demonstrated a shorter induction-to-expulsion interval among those randomized to mechanical dilation, whereas 6 studies demonstrated a similar or longer induction-to-expulsion interval. There were no significant differences reported in the frequency of any adverse outcomes between the trial arms. In addition, most studies (8/11) exhibited moderate to high levels of bias. In an analysis of the 3 studies deemed to have a low risk of bias, 1 (n=60) demonstrated a longer induction-to-expulsion interval with adjunctive laminaria, 1 (n=60) demonstrated a shorter induction-to-expulsion interval with adjunctive intracervical Foley balloon catheter use, and 1 demonstrated no difference in the induction-to-expulsion interval with adjunctive Dilapan-S use (n=180). CONCLUSION: Only a small number of studies, most of which were of low quality, assessed mechanical dilation for induction termination. The results of these studies were inconsistent in terms of the induction-to-expulsion interval of adjunctive mechanical methods in comparison with medication management alone. Studies did not reveal significant differences between the groups in adverse outcomes. Further research should investigate the use of mechanical dilation at the time of induction termination using high-quality methods.
