Temporary placement of a fully covered self-expandable metal stent in the pancreatic duct for management of symptomatic refractory chronic pancreatitis: preliminary data (with videos)

Management of distal malignant biliary obstruction with the ComVi stent, a new covered metallic stent

“…A removable covered metallic stent not only can be replaced with a new stent easily. It also can be applied for benign and resectable malignant tumors [19]. The ComVi stent can be removed as easily as the CWS.…”

A Duodenal Ulcer Caused by Pancreatic Ductal Hypertension with Chronic Pancreatitis

“…Dilation by a 10-Fr stent instead of a 7-Fr stent might prevent the development of this type of duodenal ulcer. Recent studies performed with specially made auto-expandable metallic stents have shown a partial improvement in the patients' pain after stent placement (23,24). Covered metallic stenting is another possible method that might have been useful for treating stenosis of the MPD in the present case.…”

Chronic pancreatitis

“…Several studies have shown the efficacy of endotherapy in patients with CP and PD strictures (Table 21.1) [16,[20][21][22][23][24][25][26][27][28][29]. Early series with a single plastic stent (PS) ± stricture dilation reported good short-term pain relief (70-94%).…”

“…During a median follow-up period of 38 months, 84% of patients were pain-free after stent removal. The placement of a self-expandable metal stent (SEMS) has been reported in an attempt to maintain PD patency for a long term and reduce the number of interventions required for benign stricture management [27][28][29][30]. In a study from Brussels with SEMS placement for benign PD obstruction, 20 patients treated with uncovered SEMS (USEMS) had immediate pain relief [30].…”

“…However, stent migration (n = 8) was a main complication in those with PCSEMS or FCSEMS insertion. Recent studies have reported relief of pain in 90-100% of cases while stents were in place and there was resolution of PD strictures in 67-90% of patients treated with temporary FCSEMS [27][28][29]. However, long-term follow-up data are lacking.…”
