BACKGROUND: A solitary fibrous tumor (SFT) is a rare mesenchymal tumor that occurs mostly in pleural sites, and an SFT occurring in the ischiorectal fossa is extremely rare. Because of the rarity, there are few reports detailing an SFT in the ischiorectal fossa. CASE PRESENTATION: A pararectal tumor was incidentally found in a 42-year-old man during a routine medical examination. The patient had no symptoms and no previous medical history. In the physical examination, a smooth-margined and hard elastic mass was felt, and in a digital rectal examination, the rectal mucosa appeared normal...

PURPOSE: Anal fistula is an abnormal tract or cavity between the anal canal and perianal skin. Surgical treatment of anal fistulas requires the identification of the course of the primary and secondary tracts and their relation with the sphincter musculature in order to appropriately manage them and drain any abscess. Physical examination alone is not as accurate as imaging modalities in detecting these features of the fistula, and recurrences are usually due to missed or inadequately managed infective components...

BACKGROUND AND AIMS: Endolumenal therapies serve as a treatment option for gastroesophageal reflux disease (GERD). This study aimed to determine if magnets could be placed endoscopically using the adventitial layer creating a sub-adventitial space near the esophagogastric junction to augment the lower esophageal sphincter using the submucosal endoscopy. METHODS: This study consisted of 2 phases, ex vivo and in vivo, with domestic pig esophagus. A long submucosal tunnel was made at mid to lower esophagus...

Spinal cord biopsy is a difficult procedure fraught with the risk of false-negative results or even misdiagnosis in up to 30% of cases. Differential diagnoses of spinal cord lesions include a wide range of inflammatory, infectious and neoplastic diseases. Given the importance of correctly managing these pathologies, it is crucial to avoid delays in making the correct diagnosis in order to improve the patient's outcome. We present here the case of a 21-year-old male with rapidly progressing sphincter and lower limb motor dysfunctions up to complete paraplegia with evidence of thoracic spinal cord lesion on magnetic resonance imaging...

PURPOSE OF REVIEW: There have been significant developments in the diagnosis, clinical approach, and management of patients with recurrent acute pancreatitis (RAP) in the last decade. This review systematically summarizes our current understanding of RAP. NEW FINDINGS: Gallstones and alcohol are common causes of RAP. Non-alcohol non-biliary RAP (nAnB RAP) is a difficult group of patients after excluding these two causes because extensive workup is required to elucidate the etiology...

Background: The initial approach to gastroesophageal reflux disease (GERD) management typically involves lifestyle modification and medical therapy utilizing acid reducing agents such as histamine blockers and proton pump inhibitors. In severe cases refractory to such treatments, surgical therapy may be indicated. The gold standard for surgical treatment of GERD is the laparoscopic Nissen fundoplication. In recent years, a new technique known as magnetic sphincter augmentation (MSA) has been developed using the Linx™ Reflux Management System...

BACKGROUND & AIMS: The neuropathophysiology of fecal incontinence (FI) is incompletely understood. We examined the efferent brain-anorectal and spino-anorectal motor-evoked potentials (MEP) to characterize the locus of neuronal injury in patients with FI. METHODS: We performed bilateral transcranial, translumbar, and transsacral magnetic stimulations in 27 patients with FI (19 female) and 31 healthy individuals (controls, 20 female) from 2015 through 2017. MEPs were recorded simultaneously from the rectum and anus using 4 ring electrodes...

Patients with chronic spinal cord injury (SCI) cannot urinate at will and must empty the bladder by self-catheterization. We tested the hypothesis that non-invasive, transcutaneous magnetic spinal cord stimulation (TMSCS) would improve bladder function in individuals with SCI. Five individuals with American Spinal Injury Association Impairment Scale A/B, chronic SCI and detrusor sphincter dyssynergia enrolled in this prospective, interventional study. After a two-week assessment to determine effective stimulation characteristics, each patient received sixteen weekly TMSCS treatments and then received "sham" weekly stimulation for six weeks while bladder function was monitored...

BACKGROUND: Anodal transcranial direct current stimulation (tDCS) has demonstrated effects on corticobulbar excitability and swallowing function as assessed via clinical rating scales in stroke cohorts. Biomechanical effects of anodal tDCS on swallowing remain largely unexplored. We investigated how anodal tDCS applied over the floor of mouth (FOM) representation on the primary motor cortex affects swallowing biomechanics in healthy participants. METHODS: Anodal and sham tDCS were applied for 20 minutes at 1...

BACKGROUND: Intestinal metaplasia represents an esophageal mucosal transformation due to uncontrolled gastroesophageal reflux disease. Fundoplication has been shown to lead to regression of disease. Magnetic sphincter augmentation is an alternative to fundoplication that effectively treats reflux disease. Initially, patients with intestinal metaplasia were not considered candidates for device placement, so outcomes in these patients are unknown. METHODS: A retrospective review of all patients who underwent magnetic sphincter augmentation device placement between 2007 and 2017 was performed...

BACKGROUND AND AIMS: GERD patients frequently complain of regurgitation of gastric contents. Medical therapy with proton-pump inhibitors (PPIs) is frequently ineffective in alleviating regurgitation symptoms, because PPIs do nothing to restore a weak lower esophageal sphincter. Our aim was to compare effectiveness of increased PPI dosing with laparoscopic magnetic sphincter augmentation (MSA) in patients with moderate-to-severe regurgitation despite once-daily PPI therapy. METHODS: One hundred fifty-two patients with GERD, aged ≥21 years with moderate-to-severe regurgitation despite 8 weeks of once-daily PPI therapy, were prospectively enrolled at 21 U...

A total laparoscopic fundoplication has become the procedure of choice for the surgical treatment of gastroesophageal reflux disease in patients with normal esophageal motility, with reduced postoperative pain, faster recovery and similar long-term outcomes compared to conventional open total fundoplication. Most controversial surgical aspects are the division of the short gastric vessels and the insertion of a bougie to calibrate the wrap. The anterior 180° and the posterior partial fundoplications lead to similar control of heartburn when compared to total fundoplication with lower risk of dysphagia...

Use of the magnetic sphincter augmentation (MSA) device for the laparoscopic treatment of gastroesophageal reflux disease is increasing since the first clinical implant performed a decade ago. The MSA procedure is a minimally invasive and highly standardized surgical option for patients who are partially responders to proton-pump inhibitors, which have troublesome regurgitation or develop progressive symptoms despite continuous medical therapy. The procedure has proven to be highly effective in improving typical reflux symptoms, reducing the use of proton-pump inhibitors, and decreasing esophageal acid exposure...

BACKGROUND: The magnetic sphincter augmentation (MSA) device was initially implanted with minimal hiatal dissection (MHD) at the diaphragmatic hiatus. Due to concern of possible MSA device dysfunction if herniated into an occult or small hiatal hernia, and increased understanding to the role of defective crura in reflux disease, the operative procedure was changed to planned obligatory dissection (OD) of the hiatus at the time of all implantations. METHODS: Between December 2012 and September 2016, 182 patients underwent MSA implant at a single medical center and have complete records available for review through September 2017...

Hepaticojejunostomy, which is the "gold standard" procedure for repairing postoperative biliary strictures, predisposes patients to reflux cholangitis from loss of sphincter of Oddi. The aim of this study was to assess the sphincter-preserving biliary reconstruction approach to repair postoperative biliary stricture. An autologous vascularized stomach flap was prepared and used to repair biliary defect caused by postoperative biliary stricture. Patient clinical data were analyzed retrospectively and long-term prognosis was evaluated based on the Lillemoe standard...

Electric stimulation therapy (EST) and magnetic sphincter augmentation (MSA) represent novel methods for the surgical treatment of gastroesophageal reflux disease (GERD). The aim of this review was to assess the effectiveness and safety of EST and magnetic sphincter augmentation device (MSAD) comapred to laparoscopic fundoplication (LF) and proton pump inhibitor therapy (in case of EST). We performed a systematic literature search without restrictions on publication dates in five electronic databases (MEDLINE, EMBASE, the Cochrane library, PubMed, and Centre for Reviews and Dissemination), complemented by hand search, search in trial registries, and documentation provided by the manufacturers...

Antireflux surgery anatomically restores the antireflux barrier and is a therapeutic option for proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease or PPI intolerance. Laparoscopic fundoplication is the standard antireflux surgery, though its popularity has declined due to concerns regarding wrap durability and adverse events. As the esophagogastric junction is an anatomically complex and dynamic area subject to mechanical stress, wraps are susceptible to disruption, herniation or slippage...
