Percutaneous extraction of residual post-cholecystectomy gallstones through the T-tube tract

Purpose: In the present study, the effectiveness and safety of minimally invasive percutaneous extraction of residual post-cholecystectomy gallstones through the T-tube tract were assessed. Material and methods: Between 2000 and 2015, 12 patients (seven women and five men, mean age 78 ± 8 years) after open cholecystectomy with common bile duct exploration and T-tube drainage underwent percutaneous extraction of residual gallstones through the T-tube tract. Results: The intervention was successful in 92% (11/12). In seven patients complete extraction of the retained gallstones was achieved, and in four cases partial extraction combined with passage of small residual fragments to the duodenum was obtained. In one case the extraction attempt was ineffective. Mild haemobilia was observed in two patients. No mortality or major complications were observed. Conclusions: Our findings are consistent with literature data and confirm that percutaneous extraction of residual post-cholecystectomy gallstones through the T-tube tract is an effective and safe treatment method. Although the presented technique is not a novel approach, it can be beneficial in patients unsuitable for open surgery or laparoscopic intervention when ERCP attempt occurs ineffective or there exist contraindications to ERCP.
