Internal herniation as a major cause of intestinal obstruction

Abstract

Objectives: To evaluate internal herniation as a rare cause of intestinal obstruction.Materials and Methods: Files of 18 cases, operated due to internal herniation between 2000 and 2006 at Selcuk University, Meram School of Medicine, General Surgery Department, were reviewed retrospectively. Sixteen patients (88.8%) were male (mean age: 58.2 years; range: 42-67) and 2 were female (mean age: 56.5 years; range: 52-61).Cases were grouped according to the location of internal herniation, and the clinical findings and applied treatment strategies were evaluated. Results: All patients were taken into surgical operation after preoperative preparations were completed. Findings were as follows: 6 cases of paraduodenal internal herniation, 4 of internal herniation through a defect in the terminal mesoileum, 2 of herniation through a defect in the falciform ligament, 2 of herniation through a defect in the omentum majus, 1 of herniation to the recessus over the bladder, 2 of herniation through a defect in the transverse mesocolon and 1 iatrogenically caused internal herniation through a defect in the mesojejunum. Conclusion: In an adult patient with findings of intestinal obstruction, diagnosis is difficult. Most cases presented to date are incidental findings during laparotomy, and surgical treatment is necessary. Copyright © 2008 S. Karger AG.
