    (Thieme, 2017-02) Yang, Dennis; Amin, Sunil; Gonzalez, Susana; Mullady, Daniel; Edmundowicz, Steven A.; DeWitt, John M.; Khashab, Mouen A.; Wang, Andrew Y.; Nagula, Satish; Buscaglia, Jonathan M.; Bucobo, Juan Carlos; Wagh, Mihir S.; Draganov, Peter V.; Stevens, Tyler; Vargo, John J.; Khara, Harshit S.; Diehl, David L.; Keswani, Rajesh N.; Komanduri, Srinadh; Yachimski, Patrick S.; Prabhu, Anoop; Kwon, Richard S.; Watson, Rabindra R.; Goodman, Adam J.; Benias, Petros; Carr-Locke, David L.; DiMaio, Christopher J.; Department of Medicine, IU School of Medicine
    Background and study aims Data on clinical outcomes of endoscopic drainage of debris-free pseudocysts (PDF) versus pseudocysts containing solid debris (PSD) are very limited. The aims of this study were to compare treatment outcomes between patients with PDF vs. PSD undergoing endoscopic ultrasound (EUS)-guided drainage via transmural stents. Patients and methods Retrospective review of 142 consecutive patients with pseudocysts who underwent EUS-guided transmural drainage (TM) from 2008 to 2014 at 15 academic centers in the United States. Main outcome measures included TM technical success, treatment outcomes (symptomatic and radiologic resolution), need for endoscopic re-intervention at follow-up, and adverse events (AEs). Results TM was performed in 90 patients with PDF and 52 with PSD. Technical success: PDF 87 (96.7 %) vs. PSD 51 (98.1 %). There was no difference in the rates for endoscopic re-intervention (5.5 % in PDF vs. 11.5 % in PSD; P = 0.33) or AEs (12.2 % in PDF vs. 19.2 % in PSD; P = 0.33). Median long-term follow-up after stent removal was 297 days (interquartile range [IQR]: 59 - 424 days) for PDF and 326 days (IQR: 180 - 448 days) for PSD (P = 0.88). There was a higher rate of short-term radiologic resolution of PDF (45; 66.2 %) vs. PSD (21; 51.2 %) (OR = 0.30; 95 % CI: 0.13 - 0.72; P = 0.009). There was no difference in long-term symptomatic resolution (PDF: 70.4 % vs. PSD: 66.7 %; P = 0.72) or radiologic resolution (PDF: 68.9 % vs. PSD: 78.6 %; P = 0.72) Conclusions There was no difference in need for endoscopic re-intervention, AEs or long-term treatment outcomes in patients with PDF vs. PSD undergoing EUS-guided drainage with transmural stents. Based on these results, the presence of solid debris in pancreatic fluid collections does not appear to be associated with a poorer outcome.

    Transpapillary drainage has no added benefit on treatment outcomes in patients undergoing EUS-guided transmural drainage of pancreatic pseudocysts: a large multicenter study
    (Elsevier, 2016-04) Yang, Dennis; Amin, Sunil; Gonzalez, Susana; Mullady, Daniel; Hasak, Stephen; Gaddam, Srinivas; Edmundowicz, Steven A.; Gromski, Mark A.; DeWitt, John M.; El Zein, Mohamad; Khashab, Mouen A.; Wang, Andrew Y.; Gaspar, Jonathan P.; Uppal, Dushant S.; Nagula, Satish; Kapadia, Samir; Buscaglia, Jonathan M.; Bucobo, Juan Carlos; Schlachterman, Alex; Wagh, Mihir S.; Draganov, Peter V.; Jung, Min Kyu; Stevens, Tyler; Vargo, John J.; Khara, Harshit S.; Huseini, Mustafa; Diehl, David L.; Keswani, Rajesh N.; Law, Ryan; Komanduri, Srinadh; Yachimski, Patrick S.; DaVee, Tomas; Prabhu, Anoop; Lapp, Robert T.; Kwon, Richard S.; Watson, Rabindra R.; Goodman, Adam J.; Chhabra, Natasha; Wang, Wallace J.; Benias, Petros; Carr-Locke, David L.; DiMaio, Christopher J.; Department of Medicine, IU School of Medicine
    Background and Aims The need for transpapillary drainage (TPD) in patients undergoing transmural drainage (TMD) of pancreatic fluid collections (PFCs) remains unclear. The aims of this study were to compare treatment outcomes between patients with pancreatic pseudocysts undergoing TMD versus combined (TMD and TPD) drainage (CD) and to identify predictors of symptomatic and radiologic resolution. Methods This is a retrospective review of 375 consecutive patients with PFCs who underwent EUS-guided TMD from 2008 to 2014 at 15 academic centers in the United States. Main outcome measures included TMD and CD technical success, treatment outcomes (symptomatic and radiologic resolution) at follow-up, and predictors of treatment outcomes on logistic regression. Results A total of 375 patients underwent EUS-guided TMD of PFCs, of which 174 were pseudocysts. TMD alone was performed in 95 (55%) and CD in 79 (45%) pseudocysts. Technical success was as follows: TMD, 92 (97%) versus CD, 35 (44%) (P = .0001). There was no difference in adverse events between the TMD (15%) and CD (14%) cohorts (P = .23). Median long-term (LT) follow-up after transmural stent removal was 324 days (interquartile range, 72-493 days) for TMD and 201 days (interquartile range, 150-493 days) (P = .37). There was no difference in LT symptomatic resolution (TMD, 69% vs CD, 62%; P = .61) or LT radiologic resolution (TMD, 71% vs CD, 67%; P = .79). TPD attempt was negatively associated with LT radiologic resolution of pseudocyst (odds ratio, 0.11; 95% confidence interval, 0.02-0.8; P = .03). Conclusions TPD has no benefit on treatment outcomes in patients undergoing EUS-guided TMD of pancreatic pseudocysts and negatively affects LT resolution of PFCs.
