“…Defecography was introduced by Burhenne [5]. Among female patients who underwent defecography, anterior rectocele was the most prevalent disease [6]. Emptying of the rectal ampulla was a significant quantitative marker.…”

Usefulness of Fecoflowgram for Assessment of Defecation after Intersphincteric Resection

Aim: We have developed an imaging functional assessment of defecation after partial intersphincteric resection (ISR) by fecoflowgram obtained by defecography. Patients and Methods: Between January 2012 and December 2014, 6 patients with temporary ileostomy who underwent partial ISR for lower rectal cancer at our hospital were enrolled in this study. Defecography was performed 2 weeks after closure of the ileostomy. The defecation of all patients was evaluated by defecography and a fecoflowgram calculated from defecography. During the same period, the control group was comprised of 2 male and 2 female healthy volunteers. Results: The descent of the perineum and linearization of the anorectal angle was observed relative to normal defecation in the healthy volunteers. All barium was discharged by a single abdominal pressure within 5 s in the controls. In patients after partial ISR, all barium could not be discharged by a single abdominal pressure. The time course of pressure distribution after ISR was lower than that of healthy volunteers, which could not be evaluated by defecography. Defecation time in patients following ISR was longer than that of healthy volunteers. Conclusion: Fecoflowgrams calculated from defecography seem to be useful for functional assessment of defecation after rectal resection.

“…Defecography is a radiographic examination that provides a dynamic evaluation of the pelvic oor while the patient is at rest, squeezing, coughing, and straining to evacuate 150 mL of barium paste inserted into the rectosigmoid. The evacuation rate was determined by comparing images taken before and after defecation using ImageJ to quantify the change in barium retention within the rectum [11]. Post-ESD defecography was performed to evaluate the presence of barium paste incontinence and decreased evacuation rate (< 50%).…”

Background:Endoscopic submucosal dissection (ESD) is a specific procedure that utilizes an electrosurgical knife for en-bloc resectioning large tumors. However, no study has examined the effect of ESD on the defecation function of patients with rectal tumors. We aimed to investigate the potential effects caused by ESD by analyzing changes in the morphology and movement of the anorectum pre- and post-ESD. Methods: This prospective observational study included 11 patients with anorectal tumors who underwent ESD between April 2020 and February 2022. Pre-ESD assessments includedanorectal manometry and defecography. Post-ESD assessments were conducted 2 months later, including anorectal manometry, defecography, and proctoscopy for ulcer and stenosis evaluation. Results: The median patient age was 73 years, including seven males and four females. Eight (73%) patients had rectal Rb lesions, with a resection range of one-third (0.33). Resection reached the dentate line in six cases (55%). No cases of perforation, delayed bleeding, or delayed perforation occurred. In the patients with post-ESD mucosal defects involving the dentate line, the median of functional anal canal length significantly decreased from (3.4 cm pre-ESD to 2.8 cm post-ESD, p = 0.04). Defecography revealed one case with incomplete evacuation (< 50%) and incontinence post-ESD. Interestingly, patients with pre-existing rectoceles noted resolution of lesions post-ESD. None of the patients reported daily constipation or fecal incontinence. Conclusions: While rectal ESD is unlikely to cause significant real-world defecation difficulties, alterations in rectal and anal canal morphology and function may occur if the dentate line is involved in the resection range.
