ABSTRACT
INTRODUCTION: There is still uncertainty regarding the efficacy and optimal modalities of extracorporeal shock wave lithotripsy (ESWL) in the treatment of chronic pancreatitis. The aims of the present study were to assess the safety and the efficacy of ESWL, either alone or followed by therapeutic endoscopic retrograde cholangiopancreatography (adjuvant ERCP) and to determine predictive factors of efficacy, in a real-life setting. PATIENTS AND METHODS: This study included all consecutive patients who underwent an ESWL in a single University Hospital between 2001 and 2012. The indication for ESWL was obstructive stone(s) of the main pancreatic duct resulting in either painful chronic pancreatitis or recurrent acute pancreatitis. Success was defined by resolution of pain, no analgesic treatment, no acute pancreatitis and no surgical treatment for chronic pancreatitis 6 months after the ESWL. RESULTS: One hundred and forty-six patients were studied; 6/146 (4%) had a complication of ESWL. Among the 132 patients in whom follow-up was completed, 91 (69%) had an adjuvant ERCP. After 6 months of follow-up, 100/132 (76%) patients achieved success. In multivariate analysis, the single significant predictive factor of the success of the ESWL treatment was chronic pain (p = 0.03). Patients who had chronic pain and needed opioid treatment had less chance of success than patients without chronic pain (OR 95%CI 0.31 [0.07-1.14]). We found no difference in the success rates between patients who underwent adjuvant ERCP and those who had ESWL only (p = 0.93). CONCLUSION: This study shows that the ESWL is a safe and effective treatment for patients with chronic pancreatitis and obstructive stones within the main pancreatic duct. Systematic association with therapeutic ERCP appears to provide no additional benefit and is therefore not recommended.

Hepatitis B reactivation after chemotherapy is well known when Ag HBs is positive. Recommendation is to give preventive antiviral treatment before starting chemotherapy. The reactivation when there is only an anti-HBc antibody is rare. We report the case of a woman who developed an hepatitis B reactivation two weeks after the end of a chemotherapy for a high grade non Hodgkin lymphoma. Before chemotherapy, hepatitis B virus serology was positive only for anti-HBc antibody and viral load was negative. She had a fulminant hepatitis with fatal issue although a treatment by lamivudine and adefovir was rapidly started. In the literature, only 13 cases of patients with positive anti body anti-HBc alone who developed an hepatitis B reactivation after chemotherapy have been reported.
