Percutaneous Drainage of Pelvic Fluid Collection

ABSTRACT

PURPOSE: To evaluate safe access route and success rate of percutaneous drainage of pelvic fluid collection. MATERIALS AND METHODS: The 35 percutaneous drainages of pelvic fluid collection under the CT and fiuorosocpic guidance were done in 32 patients. The anterior transabdominal approach was done in 20 patients, while the nine patients used the transgluteal approach through greater sciatic foramen. Three patients , who had septated or noncommunicating abscesses, underwent drainage using both approaches. The catheter was removed when the patient's symptom and laboratory data were improved or the amount of drainage and the size of fluid collection were markedly reduced. Success, partial success and failure were classified. RESULT: The causes of fluid collection were complication of intraabdominal operation in 27 patient. The diagnosis after drainage included abscess(21), Ioculated ascites(6), and hematoma(4). The 27 cases(30 procedure) were treated successfully and the mean duration of catheter insertion was 10 days. The partial successes were two cases(2 procedures), which had palliative purpose. Three cases(3 procedures) were failed, which were multiple Ioculated ascites of pancreatic origin(2) and recurrent abscess(I). The significant complication during the procedure or drainage was not noted. CONCLUSION: The percutaneous drainage .under CT and fluoroscopy was effective technique for the management of pelvic. fluid collection, using anterior transperitoneal and transgluteal route through greater sciatic foramen.
