Examination of 93 cases of perianal warts and suggestion of a new classification.

Purpose: The anatomical distribution of perianal warts is associated with patient characteristics such as sexual orientation. The purpose of this study is to confirm this experiential knowledge using a quantitative classification system and analysis and to obtain findings useful for future treatment.

Methods: From January 2014 to December 2020, 93 patients with perianal warts presented to our hospital.

Safety and Effectiveness of Aortic Occlusion for Those Undergoing Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA): A Retrospective Single-Center Study.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used to temporarily control bleeding and maintain the cerebral and coronary blood flow in cases in which it is difficult to control hemorrhagic shock. However, the safety and effectiveness of REBOA remains uncertain.

Objectives: This study aimed to estimate the safety and effectiveness of aortic occlusion in patients who undergo REBOA catheter placement.

Splenic flexure volvulus in a child with chronic idiopathic intestinal pseudo-obstruction syndrome.

Splenic flexure volvulus in a child with chronic idiopathic intestinal pseudo-obstruction syndrome is extremely rare. Here we present a case report of this unusual condition in a 7-year-old girl. The splenic flexure volvulus was managed by pressure reduction from the cecal antegrade continence enema, after which elective resection of the splenic flexure and primary anastomosis were performed because she had similar attacks during 4 months after the first detorsion.

Myoepithelial hamartoma causing small-bowel intussusception: a case report and literature review.

We report an unusual case of a 5-month-old girl who suffered an ileo-ileal intussusception that was not reduced by hydrostatic reduction. Surgical treatment revealed that the leading point was a tumor 1.5 cm in diameter.

Three-dimensional computed tomographic images of pelvic muscle in anorectal malformations.

Purpose: The anatomy of the pelvic flower muscles based on investigation of gross section slides of a specimen does not always correspond with those described by Pena. Therefore, we restudied the anatomy with 3-dimensional (3D) images of the pelvic muscle produced with computed tomography.

Methods: Thirty-eight patients with anorectal malformations before anorectoplasty were investigated with a multi-detector row helical computed tomography (MRH-CT).

The usefulness of dynamically balanced FFE WATS-MR imaging with kinematic display for studying pediatric gastrointestinal disease.

Abnormalities in gastrointestinal movement underlie various symptoms in the pediatric population. Although fluoroscopic, manometry, and ultrasonography remain important tools for studying gastrointestinal movement, none can depict the whole gastro-intestine full-size without radiation. The purpose of this study was to evaluate whether kinematic water selective excitation MR imaging (WATS-MR cine) could reveal gastrointestinal movement in childhood.

Left paraduodenal hernia leading to protein-losing enteropathy in childhood.

A 3-year-old girl presented with a protein-losing enteropathy caused by left paraduodenal hernia, as diagnosed by computed tomography and a small-bowel follow-through image. The patient received surgical treatment, and her postoperative course was uneventful. Nineteen days later, the serum protein and albumin had recovered to normal levels.
