INTRODUCTION: A significant number of internationally adopted children have congenital birth defects. As a specialist center for colorectal diagnoses, we evaluate such children with an anorectal malformation (ARM) and have found that a significant number need a reoperation. Knowledge of the common complications following ARM surgery has led us to develop treatment algorithms for patients with unknown past medical and surgical history, a situation typically encountered in the adopted population...

PURPOSE: For several decades, the low anterior resection (LAR) with total mesorectal excision (TME) has been the gold standard for treating patients with rectal cancer. Up to 90% of patients undergoing sphincter-preserving surgery will have changes in bowel habits, so-called 'anterior resection syndrome.' This study examined patients' continence after a LAR for the treatment of rectal cancer. METHODS: This prospective study was performed between September 2014 and August 2015 at the National Cancer Institute and included 30 patients who underwent anorectal manometry preoperatively and at 3 and 4 months after a LAR, but 10 were excluded from further evaluation for various reasons...

BACKGROUND: Sphincter-preserving procedures for the treatment of transsphincteric fistulas fail in at least one out of every three patients. It has been suggested that failure is due to ongoing disease in the remaining fistula tract. Cytokines play an important role in inflammation. At present, biologicals targeting cytokines are available. Therefore, detection and identification of cytokines in anal fistulas might have implications for future treatment modalities. The objective of the present study was to assess local production of a selected panel of cytokines in anal fistulas, including pro-inflammatory interleukin (IL)-1β and tumor necrosis factor α (TNF-α)...

BACKGROUND: The physiologic assessment of anal sphincters in cases of posttraumatic fecal incontinence is a fundamental step in planning operative treatment. In this study, we evaluate the correlation between size of anal sphincter defect, anal pressures, and clinical symptoms in patients with posttraumatic fecal incontinence. We also investigate the impact of patients' age, sex, and type of trauma on this correlation. METHODS: Records of 70 patients fitting the study's eligibility criteria were collected retrospectively from the archives of Mansoura University Hospitals' colorectal surgery unit...

According to recent studies, mesenchymal stromal cells (MSCs) transplanted via local or tail vein injection can improve healing after anal sphincter injury (ASI) in animal models. However, the transplanted MSCs do not generate skeletal muscle that completely resembles the natural anal sphincter structure. In the present study, we investigated whether bone marrow (BM)-derived MSCs could be induced by Galectin-1 (Gal-1) to differentiate into skeletal muscle and whether the recellularization of an acellular dermal matrix (ADM) with skeletal muscle-differentiated MSCs represents a promising approach to restore ASI in a rat model...

Lacerations are common after vaginal birth. Trauma can occur on the cervix, vagina, and vulva, including the labial, periclitoral, and periurethral regions, and the perineum. Most of these lacerations do not result in adverse functional outcomes. Severe perineal lacerations, extending into or through the anal sphincter complex, although less frequent, are more commonly associated with increased risk of pelvic floor injury, fecal and urinary incontinence, pain, and sexual dysfunction with symptoms that may persist or be present many years after giving birth...

BACKGROUND: Anal incontinence is a disabling condition that adversely affects the quality of life of a large number of patients, mainly with anal sphincter lesions. In a previous experimental work, in-vitro expanded bone marrow (BM)-derived mesenchymal stem cells (MSC) were demonstrated to enhance sphincter healing after injury and primary repair in a rat preclinical model. In the present article we investigated whether unexpanded BM mononuclear cells (MNC) may also be effective. METHODS: Thirty-two rats, divided into groups, underwent sphincterotomy and repair (SR) with primary suture of anal sphincters plus intrasphincteric injection of saline (CTR), or of in-vitro expanded MSC, or of minimally manipulated MNC; moreover, the fourth group underwent sham operation...

INTRODUCTION: Bowel dysfunction (fecal incontinence and constipation) presents in over 50% of patients after treatment of congenital anal malformations. Sacral nerve stimulation (SNS) for the treatment of fecal incontinence improves function in the majority of patients. We present a case report of the treatment of bowel dysfunction with sacral nerve stimulation in a patient with a history of an imperforate anus. PRESENTATION OF CASE: A twenty year-old female with a history of imperforate anus at birth, repaired during infancy with anorectoplasty, presented with fecal incontinence and constipation...

Transperineal ultrasound is an inexpensive, safe and painless technique that dynamically and non-invasively evaluates the anorectal area. It has multiple indications, mainly in urology, gynaecology, surgery and gastroenterology, with increased use in the last decade. It is performed with conventional probes, positioned directly above the anus, and may capture images of the anal canal, rectum, puborectalis muscle (posterior compartment), vagina, uterus, (central compartment), urethra and urinary bladder (anterior compartment)...
