REVIEW
Carolina Malagelada, Juan R Malagelada
PURPOSE OF REVIEW: Small bowel motility disorders constitute a relatively small but important segment of clinical gastroenterology. Presenting features encompass a broad range of symptom manifestations and severity: from chronic functional-type complaints to life-threatening nutritional impairment. Diagnostic assessment of patients with suspected intestinal motility disorders is often hampered by the complexity of measuring intestinal contractile activity in humans. In this review, we describe and critically comment the main current and forthcoming methodologies...

Laparoscopic sleeve gastrectomy (LSG) has reached wide popularity during the last 15 years, due to the limited morbidity and mortality rates, and the very good weight loss results and effects on comorbid conditions. However, there are concerns regarding the effects of LSG on gastroesophageal reflux disease (GERD). The interpretation of the current evidence is challenged by the fact that the LSG technique is not standardized, and most studies investigate the presence of GERD by assessing symptoms and the use of acid reducing medications only...

PURPOSE OF REVIEW: To review recent advances in achalasia diagnostics and therapeutics. RECENT FINDINGS: The cardinal feature of achalasia, impaired lower esophageal sphincter (LES) relaxation, can occur in association with varied patterns of esophageal contractility. The Chicago Classification distinguishes among these as follows: without contractility (type I), with panesophageal pressurization (type II), with premature (spastic) distal esophageal contractions (type III), or even with preserved peristalsis [esophagogastric junction (EGJ) outlet obstruction]...

OBJECTIVES: The diagnosis of chronic intestinal pseudo-obstruction (CIPO) has depended on clinical features, manometry, and imaging. This report aimed to determine the efficacy of sequencing the ACTG2 gene for diagnosis. In addition, the goal was to determine how often a mutation would be found in our randomly collected cohort of probands and those probands published previously. METHODS: Whole exome sequencing was performed in 4 probands with CIPO. Subsequently, only the ACTG2 gene was sequenced in another 24 probands (total 28)...

The regulation of gastrointestinal motility encompasses several overlapping mechanisms including highly regulated and coordinated neurohormonal circuits. Various feedback mechanisms or 'brakes' have been proposed. While duodenal, jejunal, and ileal brakes are well described, a putative distal colonic brake is less well defined. Despite the high prevalence of colonic motility disorders, there is little knowledge of colonic motility owing to difficulties with organ access and technical difficulties in recording detailed motor patterns along its entire length...

Low anterior resection (LAR) with total mesorectal excision has been considered a standard treatment for patients with rectal cancer. However, the functional outcome and life quality of laparoscopic LAR (LLAR) in Chinese patients remain unclear. A cohort of 51 Chinese patients (22 men and 29 women) who had undergone LLAR was included in this study. Anorectal manometry combined with the Wexner scores questionnaire were applied to assess functional outcome preoperatively (1 week) and postoperatively (at 3, 6 and 9 months)...

BACKGROUND AND OBJECTIVES: Rectal prolapse is often repaired laparoscopically, frequently with the use of reinforcement material. Both synthetic and biologically derived materials reduce recurrence rate compared to primary suture repair. Synthetic mesh introduces potential complications such as mesh erosion, fibrosis, and infection. Urinary bladder matrix (UBM) represents a biologically derived material for reinforcement of rectal prolapse repair with the potential to improve durability without risks of synthetic materials...

Gastroesophageal reflux disease (GERD) is a common condition that has a substantial impact on quality of life in patients and is a leading risk factor for esophageal adenocarcinoma. Now therapy with proton pump inhibitors (PPIs) is a basic method in the treatment of patients with GERD; however, one third of the patients do not respond to the therapy used. The causes of refractory GERD are a fairly large group of heterogeneous factors contributing to the inefficacy of PPIs in adequate dosage. Among these factors, there is low compliance by patients to the prescribed treatment regimen; nocturnal acid breakthrough; СУР2С19 gene polymorphism; chiasm syndrome with functional diseases of the gastrointestinal tract; non-acidic refluxes in a patient; thoracic esophageal motility disorders; the increased number and duration of transient lower esophageal sphincter relaxation periods; hiatus hernia; and misdiagnosis...

BACKGROUND: Men with passive fecal leakage represent a distinct clinical entity in which the pathophysiology remains unclear. Standard anorectal investigations fail to demonstrate consistent abnormalities in this group. Anal acoustic reflectometry is a new test of anal sphincter function with greater sensitivity and discriminatory ability than conventional anal manometry. OBJECTIVE: The aim of this study was to determine whether men with fecal leakage have an abnormality in anal sphincter function that is detectable by anal acoustic reflectometry...
