Outcomes after Transgastric Drainage of Pancreatic Duct Leaks

Purpose: To determine the outcomes of transgastric drainage (TGD) of pancreatic duct leaks (PDLs), including fluid colMaterials and Methods: Fifty-four patients who underwent attempted TGD of a PDL from 1992 to 2020 were identified. Data regarding patient comorbidities, fluid collection characteristics, technical success, drain exchanges and removals, recurrent collections, and complications were analyzed.Results: Forty-one patients (41/54, 76%) had a history of pancreatitis. Sixteen patients (16/54, 30%) had a history of recent abdominal surgery. Peripancreatic fluid collections were 11.2 cm & PLUSMN; 4.6 in greatest dimension prior to drainage. Twenty-one collections (21/54, 39%) demonstrated biochemical and/or imaging evidence of an active communication to the pancreatic duct, and 16 (16/54, 30%) of these patients had a PCF due to a direct percutaneous drain prior to TGD. TGD was technically successful in 53 patients (53/54, 98%). During the follow-up period, 46 patients (46/53, 87%) were able to undergo drain removal after resolution of the fluid collection, with a mean catheter indwelling time of 3 months and a median of 1 catheter exchange. There were 2 severe (2/53, 4%) and 4 moderate (4/53, 8%) complications, the most common of which was drain dislodgement requiring repeat transgastric puncture. Recurrent fluid collections were observed in 8 patients (8/53, 15%) after a mean of 5 months following drain removal. There were no recurrent PCFs.Conclusions: TGD of PDLs is technically feasible and efficacious in the vast majority of patients with a relatively low complication rate. This technique is effective in preventing or treating the long-term debilitating complication of PCF.

Automated summary

Transgastric drainage (TGD) is an effective and safe treatment for pancreatic duct leaks (PDLs), with high technical success and low complication rates.
