Summary: The study found that the 3-dimensional high-definition anorectal manometry (3D-HDAM) system has limited performance in diagnosing dyssynergic defecation, and anorectal pressure parameters measured with the 3D-HDAM probe poorly predict prolonged balloon expulsion time. Rectoanal pressure differential (RAPD) remains the best predictor of prolonged balloon expulsion time.

Summary: This study evaluated constipated patients using HR-ARM, BET, and defecography, and found that a reduced rectoanal gradient was the best predictor for prolonged BET and reduced rectal evacuation. Specific HR-ARM results supported a diagnosis of DD.

Summary: This study found three possibly interrelated abnormalities in DD, including aberrant activation of abdominal muscles during squeeze in DD, dyscoordination of abdominal muscles during various tasks in constipated women, and abdomino-anal dyscoordination.

Summary: Rectosigmoid accumulation of markers can differentiate DD from slow transit constipation. However, non-rectosigmoid accumulation does not exclude the presence of DD.

Summary: Functional defecation disorders consist of constipation causes related to anorectal dysfunction, with unclear etiology requiring comprehensive clinical assessment and physiological tests for accurate diagnosis, where defecography plays a crucial role in evaluation.

Summary: There is variation in the management approach for patients with obstructed defecatory symptoms between gastroenterologists and colorectal surgeons. Gastroenterologists are more likely to refer for anorectal manometry while colorectal surgeons are more likely to refer for dynamic imaging. Knowledge of dynamic imaging findings influences treatment decisions for both specialties.

Summary: This study assessed the outcomes of children with functional constipation after undergoing antegrade continence enemas (ACEs). It was found that ACEs were successful in treating severe constipation and fecal incontinence, even in patients with dyssynergic defecation.

Summary: Rectal balloon distension during simulated evacuation can improve rectoanal gradient and reduce dysynergia in patients with chronic constipation, particularly those with normal rectal sensory function and balloon expulsion test results.

Summary: This study investigated the diagnostic factor for high-grade rectal prolapse, finding that the feeling of prolapse and absent or impaired RAIR were independent factors of high-grade prolapse. Additionally, the absence or impairment of RAIR increased with the grading of rectal prolapse.

Summary: The study aimed to identify different phenotypes of solitary rectal ulcer syndrome (SRUS) by considering complaints, anatomy, and anorectal physiology. Results showed that the majority of patients had rectal ulcer as the predominant lesion, with inflammation of the rectal wall present in 42% of patients. Over half of the patients had abnormal rectal capacities and/or rectal perception, while nearly half met the criteria for obstructed defecation. Patients with faecal incontinence tended to have more self-perception of anal procidentia and were more likely to have inflammation of the rectal wall, high-grade internal rectal procidentia, and anal hypotonia.

Summary: Rectal prolapse often coexists with bowel and pelvic floor abnormalities. Surgery aims to correct the prolapse and improve function. History-taking, physical exam, and physiologic testing are important tools for surgical decision-making, while additional tests like defecography can help identify related issues for further evaluation.

Summary: Three-dimensional high-resolution anorectal manometry (3DHRAM) is a new technique that can be used to diagnose anorectal disorders and pelvic floor disorders. This study confirmed the reliability of 3DHRAM in the diagnosis of paradoxical puborectalis syndrome (PPS) compared to X-ray defaecography.

Summary: The study evaluated and compared the optimal esophageal balloon filling volume during Sigh breath, volume controlled ventilation (VCV), and pressure support ventilation (PSV). It was found that a higher filling volume was required during Sigh breath for accurate measurement of tidal changes in esophageal pressure (Pes). This highlights the importance of adjusting esophageal balloon filling volume based on the ventilation mode and intrathoracic pressure for accurate Pes assessment.

Summary: This study aimed to determine the anorectal physiological factors associated with rectocele formation. By retrospectively analyzing 32 female patients who underwent magnetic resonance defecography and anorectal function tests, it was found that increased anal sphincter pressure during defecation is correlated with rectocele size. These results suggest that treating the increased anal sphincter pressure should be considered before surgical rectocele repair to enhance patient outcomes.
