  15. Case report IX. • 2010 Apr. another 10F pancreatic stent to calibrate stenosis equilibrating prestenotic dilatation (10mm=3x10F), • no pain at dilation and further on. • Planned removal after 6 month

  16. Temporaly loss of endotherapy against surgical treatment • Prospective, randomized, open label Dutch study, 2-years follow-up • Longitudinal Wirsungo-jejunostomy, in 75% partial or total pain relief • ESWL + multiple balloon dilations with stenting (3 monthly for 27 weeks)  painless in 32% • Better quallity of life after surgery (also at the 6th week) • No significant differences in complications, hospital stay, changes in pancreatic function (carbonhydrate metabolism and elastase) , exocrine function (p=0,05) Cahen DL, Gouma DJ, Nio Y, Rauws EA, Boermeester MA, Busch OR, Stoker J, Laméris JS, Dijkgraaf MG, Huibregtse K, Bruno MJ. Endoscopic versus surgical drainage of the pancreatic duct in chronic pancreatitis. N Engl J Med. 2007;356:676-8

  17. Weak points of the study • The etical committee interrupted the study at the 19th endoscopic and 20th surgical treatment • 3 of the 4 patients previously failed by endoscopy, also failed by surgery but included only in the endoscopic group • Jacques Deviere: „the results are manipulated” • (2 pseudocysts not mentioned among the16 ESWL cases) • Old technique (stent exchange at every 3rd month + balloon dilation, 27 weeks short-term treatment)

  18. Successful endotherapy series • 89% painless after ESWL + stent implantation • 23-months„on demand” stent replacement • After 5-years follow-up  52-62% absence of pain Weber A, Schneider J, Neu B, Meining A, Born P, Schmid RM, Prinz C.

  19. Comparison of surgical and endoscopic therapy • Pancreatic duct obstruction and pain • Endotherapy vs. surgery (resection (80%),drainage (20%)) • 140 eligible pts, only 72 agreed to be randomized • Endotherapy: sphincterotomy+stenting (52 %), stone removal (23 %) • Initial success rates: similar • 5-year follow-up • Complete absence of pain (37 % vs. 14 %) Partial relief (49 % vs. 51 %) (randomized subgroup: 34 % vs. 15 % , 52 % vs. 46 %) • Increase in body weight: 20 - 25 % in the surgical group • New-onset diabetes (34 - 43 %), Dite P, Ruzicka M, Zboril V, Novotny I.:A prospective, randomized trial comparing endoscopic and surgical therapy for chronic pancreatitis. Endoscopy. 2003;35:553-8

  20. 8 centers follow-up after 2 - 12 years (mean 4.9 years) 1018 of 1211 patients (84%) structured questionnaires; no pain or only weak pain strictures (47%), stones (18%), strictures plus stones (32%) 60% endotherapy completed, 16% still receiving endoscopic treatment 24% had undergone surgery long-term success of endotherapy 86% only 65% in intention-to-treat analysis no significant differences between groups pancreatic function not positively affected Endoscopic stenting for CP Rosch T, et al.: Endoscopic treatment of chronic pancreatitis: a multicenter study of 1000 patients with long-term follow-up. Endoscopy. 2002; 34:765-71.

  21. Endoscopic stenting for CP • 93 CP patients with dominant sticture (ERCP) 9 yrs • Pain during 5.6 yrs before treatment • Stent exchanges according symptoms during 16 mos • Pain relief: 74% (only partial: 1/3) • Lasting (5 yrs) pain relief 64% • 36/49 pts painless without stent (4 yrs) • 13/49 pts relapsed, 11/13 stented again • Complications: mild pancreatitis (4), abscess (2)Binmoeller et al Endoscopy 1995,27:638 • Problems: drain occlusion albumin, bacteria, calciumSmits et al Gastrointest Endosc 1997, 45:52 • Ductal and/or parenchymal alterations ERCP + EUS 56%-68%, half remainedSherman et al Gastrointest Endosc 1996;44-276

  22. What could be the reason of the low success-rate? • Low number of patients • 3 of the 4 patients who previously failed by endoscopy, then by surgery diminished response-rate of endotherapy but not that of surgery • Open labelled study: surgical treatment more definitive „the larger the scar, the smaller the pain” • After the endoscopy the surgical treatment still possible • Complications in the surgical group: 35% and 5% severe! • Editorial recommendation: First endoscopy, the second step could be a surgical treatment Elta G.

  23. Multiple stents for calibration of pancreatic strictures in chronic pancreatitis. Á Pap, M Burai, T Gyökeres Z.Gastroenterol 2006,3: 130-135 Multiple stenting of refractory pancreatic duct strictures in severe chronic pancreatitis: long-term results.Costamagna G, Bulajic M, Tringali A, Pandolfi M, Gabbrielli A, Spada C, Petruzziello L, Familiari P, Mutignani M.Endoscopy. 2006 .38:254-9.

  24. Rational for multiple stenting • Patency increased by multiplying internal diameter of stents + space between outer surface and ductular wall • Free outlet of branch ducts assured by space between stents and the ductular wall • Definitive calibration of stenosis to 2/3 of the distal dilatation

  25. Multiple biliary and pancreatic stents with guidewire in the papilla

  26. Biliary and pancreatic stents in the corresponding ducts Pancreatic lavage with citrate (1.9%) at 1-2 ml/min for 3-5 days

  27. Results II. • No complication occurred at stenting, no new-onset diabetes developed. • Relapse-free follow-up occurred for 31.6 and 41.6 months (range 8-80) in one stent and multiple stents groups, respectively until now. Increasing the stent number prolonged the relapse free period in 2 pts. • Relapses (7-7 cases) were provoked by alcohol, smoking and heavy meals and treated mainly by multiple stenting (6 cases) or operation (2 patients).

  28. Multiple stenting of refractory pancreatic duct strictures in severe chronic pancreatitis: long-term results. Costamagna G, Bulajic M, Tringali A, Pandolfi M, Gabbrielli A, Spada C, Petruzziello L, Familiari P, Mutignani M.Endoscopy. 2006 .38:254-9. • 19 patients with severe chronic pancreatitis (16 men, three women; mean age 45 years) with a single pancreatic stent refractory dominant stricture • balloon dilation of the stricture; insertion of the maximum number of stents allowed by the stricture • removal of stents after 6 to 12 months • only one patient (5.5 %) had persistent stricture after multiple stenting • mean follow-up : 38 months • asymptomatic 84 % , symptomatic stricture recurrence 10,5% • no major complications

  29. Conclusion • Multiple pancreatic stenting with progressive calibration of stenosis can dilate the stricture without rupture, ischemia and side brach obstruction caused by aggressive balloon dilation • The relapse- free period could be prolonged also without stent in place if alcohol consumption and smoking have been stopped definitely • A well controlled, randomised study should be necessary to demonstrate advantages of multiple pancreatic stenting in comparison to surgery.
