title: Effect of increased intra-abdominal pressure due to pneumoperitoneum on liver functions and liver histopathology in a rat model with intra-abdominal sepsis.
abstract: Intra-abdominal sepsis was induced by open cecal ligation and puncture (OCLP) technique. Sixty rats were randomly divided into three equal groups each of 20. G1 was used as a control. G2 were subjected to laparotomy and closure after 12 hours from (OCLP) via the same incision. In G3, pneumoperitoneum was induced 12 hours after OCLP and maintained at 12 mmHg for about 30 minutes. Blood samples were taken for liver functions after 12 & 24 hours from OCLP procedure, and Liver biopsies were taken for histopathological examination after 24 hours. The results showed that liver functions were markedly increased in G3 after pneumoperitoneum, compared to Gs 1 & 2. The histopathological changes in liver biopsies due to sepsis were more marked in cases exposed to pneumoperitoneum than that exposed to conventional laparotomy. The intra-abdominal sepsis affected liver functions and caused pathogenesis. The increased intra-abdominal pressure induced more liver insults, compared to that gained after open surgery.
