Prenatal Diagnosis
|March 1, 2006
Summary
Prenatal diagnosis of abnormal abdominal situs is complex. Fetal MRI aids in assessing fetal anatomy and associated anomalies, improving management strategies for these challenging cases.
Area of Science:
- Medical Imaging
- Fetal Medicine
- Pediatric Surgery
Background:
- Prenatal management of abnormal abdominal situs presents challenges due to variable prognoses.
- Prognosis is significantly influenced by the presence of associated congenital malformations.
Purpose of the Study:
- To describe the prenatal management of ambiguous abdominal situs.
- To highlight the utility of fetal Magnetic Resonance (MR) imaging in assessing fetal abdominal anatomy.
- To propose a prenatal management scheme based on case reports and literature review.
Main Methods:
- Reported on two cases of ambiguous abdominal situs.
- Utilized specialized ultrasound for fetal anatomy and cardiac assessment.
- Performed amniocentesis for fetal karyotype determination.
- Employed fetal abdominal MR imaging for detailed anatomical evaluation.
Main Results:
- Abnormal situs in both cases was associated with other abdominal anomalies, including azygous continuation, biliary atresia, bowel obstruction, and polysplenia.
- Fetal MR imaging proved to be a valuable tool for assessing fetal abdominal anatomy.
Conclusions:
- Prenatal diagnosis and management of abnormal abdominal situs require a multidisciplinary approach.
- Fetal MR imaging enhances the prenatal assessment of complex abdominal anomalies.
- A proposed prenatal management scheme aims to guide clinical practice.

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.

01:25Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.

01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

01:19Abdominal Regions and Quadrants
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four quadrants...

01:23Assessment of the Abdomen III: Palpation
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
01:11Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
