Background: Intraperitoneal (IP) radioactive chromic phosphate (P32) remains investigational in the treatment of patients with ovarian and/or endometrial cancer. Single-use percutaneously placed catheters offer the advantage of therapy without additional surgery.
Methods: Between August, 1986 and October, 1992, 25 patients underwent bedside percutaneous catheter placement under local anesthesia without ultrasonographic or radiologic guidance, using a specialized central venous catheter.
Results: Catheter insertion was successful in 22 of 25 patients (88%) with good IP distribution. Of these, 18 of 22 patients (82%) underwent successful catheter placement with one attempt and 4 of 22 (18%) after one to three additional attempts. The technical failure rate was 12%. Multiple catheter placement attempts were associated with an increased incidence of complications (r = 0.63). Bowel entry occurred in 4 of 25 patients (16%) during 5 of 43 attempts at catheter placement (12%) but was without clinical sequelae. The likelihood of bowel entry significantly increased with more than two attempts (P = 0.02). A median of 39 days (range, 7-156 days) elapsed between the preceding laparotomy and catheter insertion.
Conclusions: Percutaneous catheter placement is successful and well tolerated in the majority of patients and should be considered for patients receiving IP P32.
