Mediastinal extension of a complicated pancreatic pseudocyst; a case report and literature review

BACKGROUND: Mediastinal pancreatic pseudocyst is a rare complication of acute or chronic pancreatitis. CASE PRESENTATION: This case report describes the management of a difficult case of pancreatic pseudocyst with a mediastinal extension in a patient having chronic pancreatitis. Different management strategies were used until complete resolution of this complex pseudocyst occurred using open surgical cystogastrostomy. CONCLUSION: Despite the availablity of different minimally invasive techniques to treat pancreatic pseudocysts, management of complex mediastinal pseudocyst may still require open surgical drainage procedures

Acquisitions thérapeutiques 1998 : Troubles fonctionnels

L'apparition d'une oesophagite ou d'un reflux gastro-oesophagien (ou encore l'aggravation d'un reflux préexistant) chez un certain nombre de patients après éradication de l'Helicobacter pylori constitue la nouveauté des troubles fonctionnels

Acquisitions thérapeutiques 1998 : Oncologie gastro-intestinale

Même si aucune acquisition nouvelle n'est venue embaumer l'atmosphère encore trop souvent grisâtre de l'oncologie gastro-intestinale en 1998, la nécessité d'un consilium préthérapeutique associant chirurgiens, endoscopeurs, oncologues et radio-oncologues s'impose avec encore plus de fermeté, pour tous les cancers digestifs. Les patients devraient autant que possible être inclus dans des protocoles d'études bien conduits et bénéficier d'une chirurgie oncologique optimale

Atypical, cytoplasmic and perinuclear anti-neutrophil cytoplasmic antibodies in patients with inflammatory bowel disease.

Atypical, cytoplasmic and perinuclear anti-neutrophil cytoplasmic antibodies (x-, c- and pANCA, respectively) are associated with a variety of inflammatory diseases, including inflammatory bowel disease (IBD). Anti-neutrophil cytoplasmic antibodies are more common in patients with ulcerative colitis (UC) than in patients with Crohn's disease (CD). Most publications only refer to p- and cANCA in relation to IBD. We have prospectively evaluated the reactivity of sera from 58 patients with IBD and 10 healthy controls against human neutrophils with emphasis on the distinction of the ANCA types. The sera were incubated with ethanol- and formaldehyde-fixed granulocytes to differentiate between c-, p- and xANCA. The results showed that 10 of 24 patients with UC were positive for ANCA, whereas only one of 34 patients with CD was ANCA positive. These results correspond to a sensitivity of 42%, a specificity of 97%, a negative predictive value of 91% and a positive predictive value of 75% in UC. Of the 11 ANCA-positive sera, two showed a cytoplasmic staining pattern, three showed a perinuclear and six an atypical staining pattern. The disease activity was not correlated to either the ANCA titre or to the presence of ANCA in the serum. In conclusion, ANCA are of limited value in differentiating between UC and CD. Because the majority of ANCA in patients with IBD are xANCA, these ANCA should be explored by not only incubating on ethanol-fixed granulocytes, but also on formaldehyde-fixed granulocytes
