Background And Aims: This study used postoperative defecography to characterize morphological features of defecatory disorders in patients following rectal resection. We also evaluated differences in dynamic defecatory condition depending on reconstruction methods for sphincter-saving surgery.
Materials And Methods: Subjects comprised 62 patients (male/female, 41/21; mean age, 61 years) who underwent defecography after sphincter-saving surgery for rectal cancer. Semisolid barium (100 ml) was introduced into the rectum, and images were taken in a sitting position. Characteristic dynamic findings in defecography were evaluated according to operative methods and were compared with symptoms of defecatory disorders.
Results: Defecographic findings closely associated with postoperative defecatory disorder were as follows: (1) low volume of neorectum in patients with worse incontinence grade (p < 0.05), (2) low evacuation fraction in patients with significantly impaired function such as soiling, urgency, and worsened incontinence score (p < 0.05), (3) minor alteration of anorectal angle at evacuation in patients with major soiling and worsened incontinence score (p < 0.05), and (4) barium shadow in the anal canal at rest in patients with urgency (p < 0.05). By reconstruction method, the J-pouch displayed a larger volume than straight anastomosis but a significantly wider anorectal angle than high anterior resection (HAR). Side-to-end anastomosis offered a moderate volume and a sharp anorectal angle as in HAR.
Conclusions: Defecography is useful for visualizing and characterizing defecatory disorders following rectal resection. Based on defecography, J-pouch reconstruction offers advantageous volume, while side-to-end anastomosis provides a more acute anorectal angle for patients who have received rectal resection with low anastomosis. A new reconstruction method offering both advantages was discussed.

High altitude (HA) exposure induces impairments in visual function. This study was designed to dynamically observe visual function after returning to lowland and elucidate the underlying mechanism by examining the structure and function of retina and visual pathway. Twenty-three subjects were recruited before (Test 1), and one week (Test 2) and three months (Test 3) after their return from HA (4300 m) where they resided for 30 days.

Department of Ultrasound, Second Affiliated Hospital of Fujian Medical University, No. 34 Zhongshan North Road, Licheng District, Quanzhou, 362000, Fujian, China.
Objective: To investigate the application of transperineal ultrasound for assessing pelvic floor muscle (PFM) function in male patients with constipation and to evaluate its clinical value.
Methods: The study included 32 male patients with constipation and 32 healthy controls, all of whom underwent transperineal ultrasound examinations. Measured parameters included the anorectal angle (ARA), levator plate angle (LPA), excursions of the ARA and LPA, and displacements of the bulb of the penis (BP), mid-urethra (MU), urethra-vesical junction (UVJ), and anorectal junction (ARJ) at rest, during maximal voluntary contraction (MVC), and during maximal Valsalva maneuver.

Institute of Rehabilitation Engineering and Technology, School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai, China.
Background: Artificial anal sphincter is a novel method for the treatment of fecal incontinence. Aiming at the problems of complex mechanical structure, high mechanical failure rate, large volume and poor biocompatibility of existing artificial anal sphincters, this article proposes a novel flexible artificial anal sphincter with bionic structure.
Methods: A novel flexible artificial anal sphincter was proposed with bionic structure by analogy with the puborectalis, flexible transmission by flexible tendons, good biocompatibility by using thermoplastic urethane and medical silicone, small size and lightweight.
Pelvic Floor Ultrasound Findings and Symptoms of Pelvic Floor Dysfunction During Pregnancy.
Int Urogynecol J
December 2024
Department of Development and Regeneration, Cluster Urogenital Surgery, Biomedical Sciences, KU Leuven, Herestraat 49, 3000, Louvain, Belgium.
Introduction And Hypothesis: Pregnancy and childbirth predispose to pelvic floor dysfunction (PFD), coinciding with functional and anatomical changes in the pelvic floor. To some extent, these can be assessed by transperineal ultrasound (TPUS), yet the correlation between ultrasound findings and symptoms has not been well elucidated. We hypothesised that pregnant women with PFD would show different findings at TPUS.
