Adult colonoscopy or single-balloon enteroscopy-assisted ERCP in long-limb surgical bypass patients.

Objective: The aim of this study was to evaluate the usefulness of adult colonoscopy or single-balloon enteroscopy (SBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) in long-limb surgical bypass patients.

Methods: Retrospective analysis of 16 patients with long-limb surgical bypasses who underwent therapeutic ERCP because of suspected pancreaticobiliary diseases. Small-bowel intubation was performed by peroral adult colonoscopy or SBE.

[Expression of t(11;18) and bcl-10 in gastrointestinal MALT lymphoma].

To detect chromosome translocation t(11;18) (q21;q21) and the nuclear expression of bcl-10 in gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma in Chinese, a possible API2-MALT fusion transcript specific to t(11; 18) (q21; q21) in tumors from 42 cases of primary gastrointestinal lymphoma (29 cases of low grade MALT lymphoma, 13 cases of transformed MALT lymphoma) and 40 cases of diffuse large B cell lymphoma was examined by means of RT-PCR and proved by DNA-sequencing. Bcl-10 expression was examined by immunohistochemical method. The results showed that t(11;18) (q21;q21) was 14% positive in cases of low grade MALT lymphomas and 46% positive in transformed MALT lymphomas, but none in cases of DLBCL.

[Changes of gastric mucosa histopathology after Helicobacter pylori eradication].

Objective: To investigate the relationship between Helicobacter pylori (Hp) infection and gastric cancer through the changes of gastric mucosa histopathology within 5 years after Hp eradication in Hp-positive subjects in the high incidence region of gastric cancer.

Methods: One thousand and six adults were selected from general population in Yantai, Shandong Province, the high incidence region of gastric cancer. Gastroscopy and CLO test were performed in all subjects.
