One of the critical factors for predicting the success of percutaneous catheter drainage (PCD) is the mean CT density of collection. A higher CT density suggests more necrotic solid tissue within the collection. In the present study, a novel technique for PCD of the necrotic pancreatic collection with a higher mean CT density was evaluated. It was a retrospective study of patients with acute pancreatitis (AP) who underwent PCD of pancreatic collections between May 2018 and December 2018. Patients with pancreatic collections having a CT density of &gt;30 Hounsfield Units (HU) were considered for PCD using the kissing catheter technique. This technique involved placing two catheters side-by-side through a single cutaneous entry site, as the conventional technique of PCD may not be effective. The technical details, outcomes and complications of this technique were recorded. A total of 10 patients with a mean age of 30 years underwent PCD using this technique. All patients had severe pancreatitis with a mean CT severity index of 9 (range, 8-10). The mean CT density was 37 HU (range, 32-56). Successful management with PCD alone was achieved in 8 patients. The other 2 patients underwent surgical necrosectomy. One patient who underwent surgical necrosectomy died. Minor complications occurred in 3 patients. The kissing catheter technique allows for a higher success rate of PCD compared with that of the conventional method of PCD, in collections with a higher mean CT density.
