A 72-year-old female presented with a six-month history of increased frequency of defecation, rectal bleeding, and severe
rectal pain
. Digital rectal examination and endoscopy revealed a low rectal lesion lying anteriorly. This was confirmed histologically as adenocarcinoma. Radiological staging was consistent with a T(3)N(2) rectal tumour. Following long-course chemoradiotherapy repeat staging did not identify any metastatic disease. She underwent a laparoscopic cylindrical abdominoperineal excision with en bloc resection of the coccyx and posterior wall of the vagina with a negative circumferential resection margin. The perineal defect was reconstructed with Permacol (biological implant, Covidien) mesh. She had no clinical evidence of a perineal
hernia
at serial followup. Dynamic MRI images of the pelvic floor obtained during valsalva at 10 months revealed an intact pelvic floor. A control case that had undergone a conventional abdominoperineal excision with primary perineal closure without clinical evidence of herniation was also imaged. This confirmed subclinical perineal herniation with significant downward migration of the bowel and bladder below the pubococcygeal line. We eagerly await further evidence supporting a role for dynamic MR imaging in assessing the integrity of a reconstructed pelvic floor following cylindrical abdominoperineal excision.

A rare case of a severely constipated patient with rectal aganglionosis is herein reported. The patient, who had no megacolon/megarectum, underwent a STARR, i.e., stapled transanal rectal resection, for obstructed defecation, but her symptoms were not relieved. She started suffering from severe chronic
proctalgia
possibly due to peri-retained staples fibrosis. Intestinal transit times were normal and no megarectum/megacolon was found at barium enema. A diverting sigmoidostomy was then carried out, which was complicated by an early parastomal
hernia
, which affected stoma emptying. She also had a severe diverting proctitis, causing rectal bleeding, and still complained of both
proctalgia
and tenesmus. A deep rectal biopsy under anesthesia showed no ganglia in the rectum, whereas ganglia were present and normal in the sigmoid at the stoma site. As she refused a Duhamel procedure, an intersphincteric rectal resection and a refashioning of the stoma was scheduled. This case report shows that a complete assessment of the potential causes of constipation should be carried out prior to any surgical procedure.
