A male patient, 55 years old, born in Ayacucho, with Spanish ancestors, was hospitalized through emergency referring abdominal pain, and 10 kilograms weight loss. Six months before he was diagnosed as having irritable bowel syndrome. His previous diseases were rheumatoid arthritis and intolerance to lactose. Laboratory results were: Hb 12 gr./dL, white cells 5200 per mm3, albumin 2.7 gr./dL, erythrocyte sedimentation rate 32 mm/hr., and tumor markers were negative. Radiographic study of the small bowel showed barium fragmentation, and a focal dilation in distal jejunum. Chest X-ray and CT scan of thorax, abdomen and pelvis were normal. Colonoscopy was normal for colonic mucosa, but in ileum it showed an irregular mucosa, little nodules and fewer folds than usual. Biopsy from ileum demonstrated unspecific inflammation. Upper endoscopy showed gastritis, a duodenum scar ulcer and an irregular mosaic pattern pink and white. Duodenum biopsy demonstrated short villi, chronic inflammation and an increase in the number of intraepithelial lymphocytes, all these was consistent with celiac disease Marsh 3. Antibodies anti-endomisium and anti-transglutaminase were positive. After some days he developed signs of bowel obstruction and was operated.

Peritoneal adhesion is a general complication following pelvic and abdominal surgery, which may lead to chronic abdominal pain, bowel obstruction, organ injury, and female infertility. Biodegradable polymer membranes have been suggested as physical barriers to prevent peritoneum adhesion. In this work, a transglutaminase (TGase)-catalyzed crosslinked carboxymethyl chitosan/carboxymethyl cellulose/collagen (CMCS/CMCL/COL) composite anti-adhesion membrane with various proportions of CMCS, CMCL, and COL (40/40/20, 35/35/30, 25/25/50) was developed. After crosslinking by TGase, the composite anti-adhesion membranes shown enhanced mechanical properties and improved biodegradability. Meanwhile, the high cytocompatibility of anti-adhesion membranes was proved by in vitro cell culture study. Moreover, the anti-adhesion membrane with the proportion of 25/25/50 was implanted between the artificially defected cecum and peritoneal wall in rats and following by general observation, histological examination, and inflammatory factors assay. The results indicated that the anti-adhesion membrane can significantly prevent peritoneal adhesion with negligible immunogenicity. Therefore, the composite membrane crosslinked by TGase had satisfactory anti-adhesive effects with high biocompatibility and low antigenicity, which could be used as a preventive barrier for peritoneal adhesion.
