Abstract

Radiofrequency (RF) ablation is considered as a relatively low-risk technique for treating liver malignancy. The pneumoperitoneum without peritoneal sign after RF ablation is previously unreported. A case is reported here of localized pneumoperitoneum unrelated to bowel injury following RF ablation for hepatocellular carcinoma.

Main findings

A localized pneumoperitoneum without peritoneal signs occurred following percutaneous RF ablation for hepatocellular carcinoma and was reported as unrelated to bowel injury. The authors note this presentation was previously unreported.

Outcomes measured

Pneumoperitoneum
Peritoneal signs
Bowel injury (ruled out)

Limitations

Single-patient case report
No RF exposure parameters (e.g., frequency, power, duration) reported in abstract
Causality cannot be established from a case report
