Abstract

We describe our protocol for performing decompression radiologic gastrostomy and gastrojejunostomy in patients with ascites and small-bowel obstruction. We also assess the technical success rate, the complications, and the morbidity and mortality in 45 patients who underwent radiologic gastrostomy.Forty-five consecutive patients with ascites associated with metastatic ovarian cancer underwent a radiologic gastrostomy or gastrojejunostomy with gastropexy. Six patients underwent gastrostomy, and 39 patients underwent gastrojejunostomy. Locking catheters were placed using the Seldinger technique after gastropexy in all patients. Paracentesis was performed before gastrostomy or gastrojejunostomy. Additional serial paracenteses were performed after the procedure when reaccumulation of ascites close to the site of gastropexy was detected on follow-up sonography.Forty-five procedures were attempted. The technical success rate was 97.8%. The complication rate was 15.6%. Three major complications (6.7%) and four minor complications (8.9%) occurred. One procedure-related death (2.2%) occurred 16 days after gastrojejunostomy.Radiologic gastrostomy and gastrojejunostomy can be performed safely in patients with ascites if the patients undergo paracentesis first and if the reaccumulation of ascites is prevented after tube placement. In patients with ascites, gastropexy plays an important role in preventing pericatheter leakage. Ascites and peritoneal carcinomatosis should not be considered contraindications for radiologic gastrostomy or gastrojejunostomy.
