Abbreviation for abdominal puncture, a puncture technique in which a puncture needle is inserted into the peritoneal cavity through the abdominal wall. It is often used to check the nature of the effusion to help clarify the cause, or to perform intraperitoneal administration. When a large amount of ascites causes breathing difficulties or abdominal pain, puncture can also be used to relieve symptoms. The common puncture site in internal medicine is the intersection of the umbilical cord and the anterior superior iliac spine.

Application

Abdominal puncture can be used to determine the cause of ascites (such as portal hypertension, cancer metastasis, tuberculosis, pancreatic ascites), to diagnose visceral perforation in patients with blunt abdominal trauma. It can also be used for the treatment of patients with portal hypertension, especially those who have difficulty breathing, pain or oliguria due to a large amount of ascites.

Absolute contraindications

Including severe or uncontrollable abnormal blood coagulation mechanism, intestinal obstruction or abdominal wall infection. Relative contraindications include poor patient cooperation, surgical scars at the puncture site, or severe portal hypertension with abdominal collateral circulation.
