Visualization of the Anal Dimple by Fetal MRI: Is It Feasible?

Introduction: The aim of this study was to determine the feasibility of fetal MRI in identifying the normal anal dimple (AD) and compare it with prenatal ultrasound (US).

Methods: Retrospective review of 130 patients with both fetal MRI and US. The gestational age (GA) was stratified into four groups: (1) 16 to 21 weeks-6 days; (2) 22 to 27 weeks-6 days; (3) 28 to 33 weeks-6 days; and (4) 34 weeks and beyond.

Visualization of the fetal anus by prenatal ultrasound for the diagnosis of anorectal malformations: is it feasible?

Purpose: The goal of this study was to determine the feasibility of identifying the anal dimple (AD) on routine prenatal ultrasound. Using the presence, absence, appearance, and location of the anal dimple as an indirect sign for possible underlying anorectal malformations (ARM), we hypothesize that evaluation of the anal dimple as part of the fetal anatomic survey may increase the sensitivity in detecting less severe ARMs.

Methods: In a prospective longitudinal observational study, pregnant women who underwent prenatal ultrasound (US) at the Colorado Fetal Care Center between January 2019 and 2020 were enrolled.

Efficacy and safety of an abbreviated perioperative care bundle versus standard perioperative care in children undergoing elective bowel anastomoses: A randomized, noninferiority trial.

Purpose: The aim was to evaluate if an abbreviated perioperative care bundle (APCB) is noninferior to the standard care, in terms of efficacy and safety, in pediatric patients undergoing bowel anastomoses.

Methods: A randomized, open, noninferiority trial with two parallel groups of equal size was carried out at the National Institute of Pediatrics in Mexico City, Mexico, from April 2016 to July 2018. The total number analyzed was 74 (37 per group).

Effectiveness of senna vs polyethylene glycol as laxative therapy in children with constipation related to anorectal malformation.

Purpose: Constipation is present in 80% of children with corrected anorectal malformations, usually associated to rectal dilation and hypomotility. Osmotic laxatives are routinely used for idiopathic constipation. Senna is a stimulant laxative that produces contractions improving colonic motility without affecting the stool consistency.
