Exploratory laparoscopy as first choice procedure for the diagnosis of giant peritoneal loose body: a case report.

Peritoneal loose body (PLB) is an extremely rare clinical entity, and its preoperative diagnosis is often difficult. We report a case of giant PLB (GPLB) confirmed by exploratory laparoscopy. A 46-year-old man was admitted to hospital with an abdominal mass and urinary frequency. He underwent clinical and laboratory tests and computed tomography (CT), which indicated a lesion at the bottom of the bladder. Exploratory laparoscopic surgery revealed a GPLB, which was subsequently removed. The patient was comfortable after surgery and was discharged 3 days later. His symptoms of frequent urination improved during the 1-month follow-up period. The egg-shaped mass excised from the peritoneal cavity measured 45 × 40 × 33 mm. This case indicates that exploratory laparoscopy can be considered as the first-choice diagnostic procedure for patients with GPLB.
