Summary
Congenital anovestibular fistula (AVF) with a normal anus in girls can be safely repaired without a colostomy. Delaying definitive surgery until infections resolve improves outcomes for AVF patients.
Area of Science:
- Pediatric Surgery
- Congenital Anomalies
- Anorectal Malformations
Background:
- Congenital anovestibular fistula (AVF) with a normal anus is a rare anorectal malformation in girls.
- This condition presents unique diagnostic and surgical challenges.
Purpose of the Study:
- To review the clinical features, management, and outcomes of congenital anovestibular fistula (AVF) with a normal anus.
- To evaluate the safety and efficacy of primary repair without colostomy.
Main Methods:
- A retrospective analysis of 24 female patients with AVF treated between 1994 and 2006.
- Evaluation of clinical presentation, surgical procedures, complications, and long-term follow-up.
Main Results:
- Most patients presented with stools exiting through perineal openings; 5 had vulvar abscesses.
- Primary repair without colostomy was performed in 22 patients.
- All patients achieved normal bowel movements post-operatively, though 5 with abscesses required reoperation.
Conclusions:
- Primary surgical repair without diverting colostomy is a safe and effective option for AVF with a normal anus.
- Deferring definitive surgery in cases of abscess or infection until healing is achieved is recommended.

01:21Inflammatory Bowel Disease V: Surgical Management
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:19Anastomoses
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

01:24Esophageal Varices-I: Introduction
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:25Hiatal Hernia
A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...
