BACKGROUND: Surgery for the treatment of recurrent pelvic malignancy is challenging. Sphincter-preserving surgery (SPS) has been applied in limited cases. Transanal endoscopic approach (TEA) has been used for primary rectal cancer, predominantly for hybrid transabdominal-transanal total mesorectal excision. Here, we describe the use of TEA as a hybrid approach in a case of recurrent ovarian cancer. CASE PRESENTATION: A 59-year-old woman had recurrence of serous ovarian adenocarcinoma in the vaginal stump, near the site of anastomosis from a rectal resection 18 months previously...

AIM: Despite modern medical techniques, anatomically proximal (high) anal fistulas are still a challenge in colorectal surgery. In previous years, the standard of care was complete fistulectomy with a high rate of continence disorders. Over the past 20 to 30 years, sphincter-saving procedures have gained wide acceptance. They represent the technique used in these cases. Additionally, many patients received indefinite treatment, namely the placement of a seton to maintain surgical drainage...

BACKGROUND: Achalasia is a rare motility disorder characterized by myenteric neuron and interstitial cells of Cajal (ICC) abnormalities leading to deranged/absent peristalsis and lack of relaxation of the lower esophageal sphincter. The mechanisms contributing to neuronal and ICC changes in achalasia are only partially understood. Our goal was to identify novel molecular features occurring in patients with primary achalasia. METHODS: Esophageal full-thickness biopsies from 42 (22 females; age range: 16-82 years) clinically, radiologically, and manometrically characterized patients with primary achalasia were examined and compared to those obtained from 10 subjects (controls) undergoing surgery for uncomplicated esophageal cancer (or upper stomach disorders)...

BACKGROUND AND AIMS: We recently developed 2 novel 3D high-resolution manometry (HRM) metrics of esophagogastric junction (EGJ) contractility to differentiate the lower esophageal sphincter (LES) and crural diaphragm (CD) elements of EGJ pressure. This study aimed to compare these metrics to the EGJ-contractile integral (EGJ-CI) and to analyze their correlation with esophageal acid exposure time (AET) on pH-metry. METHODS: Thirty-one gastro-oesophageal reflux disease (GERD) patients and 20 control subjects underwent 24-hour pH-metry and HRM using a 3D-HRM catheter...

The aim of this work was to develop a fully coupled bolus-esophageal-gastric model based on the immersed boundary-finite element method to study the process of esophageal emptying across the esophagogastric junction (EGJ). The model included an esophageal segment, an ellipsoid-shaped stomach, a bolus, and a simple model of the passive and active sphincteric functions of the lower esophageal sphincter (LES). We conducted three sets of case studies: (1) the effect of a non-relaxing LES; (2) the influence of the tissue anisotropy in the form of asymmetrical right- and left-sided compliance of the LES segment; and (3) the influence of LES and gastric wall stiffness on bulge formation of the distal esophageal wall...

REVIEW
Javier C Angulo, Reynaldo G Gómez, Dmitriy Nikolavsky
PURPOSE OF REVIEW: Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries...

Background: To investigate the outcomes and mechanisms of low-intensity extracorporeal shock wave therapy (Li-ESWT) on stress urinary incontinence (SUI) in a vaginal balloon dilation (VBD) rat model. Methods: Thirty Sprague-Dawley rats were randomly grouped into normal controls, VBD only, and VBD with Li-ESWT. Li-ESWT was administered twice per week for 3 weeks. Afterward, all 30 rats were assessed with functional and histological studies. To explore the acute effect of Li-ESWT, another 25 rats, given intraperitoneal 5-ethynyl-2-deoxyuridine (EdU) at birth, were treated with Li-ESWT followed by assessment of vascular endothelial growth factor (VEGF) expression and endogenous progenitor cells distribution at 24 hours or 1 week after the last Li-ESWT therapy...

BACKGROUND: Meningioma is a common slow growing spinal tumour with a predilection for intradural occurrence. Patients usually present with pain followed by ataxia and sensory and sphincter problems. The gold standard treatment in these cases is gross total microsurgical resection under general anaesthesia. However, there exist high anaesthetic risk patients unsuitable for general anaesthesia. Performing spinal surgeries under local anaesthesia and sedation has been reported albeit rarely for mostly minimally invasive procedures but not for open intradural pathologies...

AIMS: The serotonin (5-HT2c) receptor is known to be involved in the mechanism of urethral closure in a model of stress incontinence. Lorcaserin (Belviq®) has received Food and Drug Administration approval for the treatment of obesity. However, it is unclear whether this selective 5-HT2c receptor agonist enhances urethral closure in stress urinary incontinence (SUI) models. Therefore, we investigated whether lorcaserin could enhance urethral closure in female rats with vaginal distention (VD)...

BACKGROUND: Pelvic MRI allows for clear delineation of anatomy in Crohn's fistula-in-ano, although its interpretation is often difficult for nonradiologists. OBJECTIVE: The aim was to develop a 3-dimensional model where fistula tracts and their relationship to the sphincter complex can be accurately defined, which can then be rotated in multiple axes by the surgeon. DESIGN: A 3-dimensional model was created based on MRI images. An additional 3-dimensional T2-weighted sequence was added to the existing MRI protocol to obtain high-resolution images...

A new species in a new genus of sea anemone, Tempuractis rinkai gen. et sp. nov., was discovered at several localities along the temperate rocky shores of Japan. The new species is approximately 4 mm in length and has been assigned to family Edwardsiidae, because it has eight macrocnemes, lacks sphincter and basal muscles, and possesses rounded aboral end. The sea anemone, however, also has a peculiar body shape unlike that of any other known taxa. This new species resembles some genera, especially Drillactis and Nematostella, in smooth column surface without nemathybomes or tenaculi, but is distinguishable from them by several morphological features: the presence of holotrichs and absence of nematosomes...

BACKGROUND: Magnetic sphincter augmentation (MSA) is a modern treatment option for gastroesophageal reflux disease (GERD); however, laparoscopic fundoplication remains the gold standard. The aim of the study was to evaluate outcomes of MSA patients at a reflux center. METHODS: A retrospective review was performed of all patients that underwent MSA between March 2012 and November 2017. Out of 110 patients, 68 with a follow-up >3 months were included. Postoperative gastrointestinal symptoms, proton pump inhibitor (PPI) intake, GERD-Health-related Quality of Life (GERD-HRQL) and alimentary satisfaction (AS) were assessed...

The disruption of coordination between smooth muscle contraction in the bladder and the relaxation of the external urethral sphincter (EUS) striated muscle is a common issue in dysfunctional bladders. It is a significant challenge to overcome for neuromodulation approaches to restore bladder control. Bladder-sphincter dyssynergia leads to undesirably high bladder pressures, and poor voiding outcomes, which can pose life-threatening secondary complications. Mixed pelvic nerves are potential peripheral targets for stimulation to treat dysfunctional bladders, but typical electrical stimulation of pelvic nerves activates both the parasympathetic efferent pathway to excite the bladder, as well as the sensory afferent pathway that causes unwanted sphincter contractions...

BACKGROUND: Perianal fistula surgery can damage the anal sphincters which may cause faecal incontinence. By measuring regional pressures, 3D-HRAM potentially provides better guidance for surgical strategy in patients with perianal fistulas. The aim was to measure regional anal pressures with 3D-HRAM and to compare these with 3D-EUS findings in patients with perianal fistulas. METHODS: Consecutive patients with active perianal fistulas who underwent both 3D-EUS and 3D-HRAM at a clinic specialised in proctology were included...

Advanced lung disease is associated with gastroesophageal reflux disease (GERD). The thoracoabdominal pressure gradient (TAPG) facilitates gastroesophageal reflux, but the effects of TAPG on gastroesophageal reflux in patients with pulmonary disease have not been well defined. Patients diagnosed with end-stage lung disease are expected to have the most extreme derangement in respiratory mechanics. The aim of this study is to explore the relationship between TAPG and reflux in lung transplant (LTx) candidates...
