We standardized an abdominal adipose tissue biopsy using a non-diathermy method performed under local anesthesia. Three cases of excessive post-operation bleeding out of 115 operations (2.61%) occurred.We conclude that an abdominal adipose tissue surgical biopsy using a non-diathermy method can be safely applied to healthy men.

Abdominal Exam IV: Acute Abdominal Pain Assessment

2023
Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Medical percussion is based on the difference in pitch between the sounds elicited by tapping on the body wall. The auditory response to tapping depends on the ease with which the body wall vibrates, and is influenced by underlying organs, strength of the stroke, and the state of the body wall. There are three main medical percussion sounds: resonance (heard over lungs), tympany (heard over...

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Abdominal palpation, if performed correctly, allows for examination of the large and relatively superficial organs; for a skilled examiner, it allows for assessment of the smaller and deeper structures as well. The amount of information that can be obtained by palpation of the abdominal area also depends on the anatomical characteristics of the patient. For example, obesity might make...

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Gastrointestinal disease accounts for millions of office visits and hospital admissions annually. Physical examination of the abdomen is a crucial tool in diagnosing diseases of the gastrointestinal tract; in addition, it can help identify pathological processes in cardiovascular, urinary, and other systems. As physical examination in general, the examination of the abdominal region is...
FAQs
Imaging guidance helps the clinician direct the sampling device toward the abnormal area rather than nearby normal tissue or surrounding structures. This targeting is especially important when the diagnostic finding is localized within an abdominal organ or mass. By improving specimen placement while limiting unnecessary injury, guidance supports more focused tissue evaluation.
Pathologists examine cellular changes in the specimen to characterize the underlying process. Additional immunohistochemical tests can help identify particular tissue features, while molecular tests provide further information when cellular findings alone are insufficient. Together, these evaluations can support recognition of infection, inflammation, fibrosis, or cancer and clarify the nature of an abnormal lesion.
Tissue analysis provides direct evidence of cellular and molecular changes within an abnormal area. That evidence can help distinguish a benign lesion from a malignant one and can also identify noncancerous processes such as infection, inflammation, or fibrosis. The resulting diagnosis gives clinicians a more specific basis for judging disease severity and planning care.
Clinicians may obtain the sample percutaneously with a needle, through an endoscopic technique, or during surgery. The source material also notes that imaging often guides the procedure, helping target the abnormal area. These approaches provide different routes for collecting tissue from abdominal organs or masses while supporting focused diagnostic evaluation.
The method can be applied to abnormal tissues involving the liver, kidneys, pancreas, and other abdominal sites. Its value extends across several disease categories because pathologic examination may reveal infection, inflammation, fibrosis, or cancer. The findings can therefore characterize an abnormal organ or mass and indicate how severe the disease may be.
Results may guide treatment selection by identifying the disease process and helping determine its severity. In some cases, tissue findings also provide a basis for assessing response to therapy over time. This makes the procedure relevant not only at initial diagnosis, but also when clinicians need pathologic information to evaluate ongoing management.
