This paper gives practical guidelines for diagnosis and treatment of chronic pancreatitis. Statements have been elaborated by working teams of experts, by searching for and analysing the literature, and submitted to a consensus process by using a Delphi modified procedure. The statements report recommendations on clinical and nutritional approach, assessment of pancreatic function, treatment of exocrine pancreatic failure and of secondary diabetes, treatment of pain and prevention of painful relapses. Moreover, the role of endoscopy in approaching pancreatic pain, pancreatic stones, duct narrowing and dilation, and complications was considered. Recommendations for most appropriate use of various imaging techniques and of ultrasound endoscopy are reported. Finally, a group of recommendations are addressed to the surgical treatment, with definition of right indications, timing, most appropriate procedures and techniques in different clinical conditions and targets, and clinical and functional outcomes following surgery. © 2010 Editrice Gastroenterologica Italiana S.r.l

Acromegaly is an infrequent disease attributable to endogenous excess of GH and IGF-I. Human studies have associated the GH-IGF-I axis with the development of colorectal cancer; however, the question of whether colorectal cancer is a problem in acromegaly is currently unresolved. We performed a cross-sectional study to assess the risk of colonic neoplasia in patients with acromegaly. Colonoscopic screening was performed in 235 patients with acromegaly at five tertiary care hospitals in Italy between January 1, 1996, and December 31, 2001. A repeat colonoscopy was performed in 121 patients after a mean interval of 32.1 months. Colonoscopic findings in patients with acromegaly were compared with those of 233 patients with nonspecific abdominal complaints who were referred for endoscopy during the study period. A total of 65 patients (27.7%) and 36 controls (15.5%) had colonic neoplasia. In 55 patients (23.4%) and 34 control subjects (14.6%), the most important findings were adenomas (odds ratio, 1.7; range, 1.1-2.5), whereas 10 patients (4.3%) and two control subjects (0.9%) had carcinoma (odds ratio, 4.9; range, 1.1-22.4). The risk of colonic neoplasia was higher for younger patients with acromegaly compared with age-matched controls. Patients with acromegaly with or without colonic neoplasia did not differ significantly for IGF-I levels or duration of disease. A neoplastic recurrence was found in 16.5% of patients who underwent follow-up; 90% of them had had a neoplasm removed at the first colonoscopy. Acromegaly carries with it a moderate, but definitive, increase in the risk of colonic neoplasia that occurs at a younger age than in the general population. Patients who are found to harbor a colonic neoplasia are at risk for recurrence.
