Two Cases of Laparoscopic Diagnosis and Treatment of Intersigmoid Hernia.

We present two cases of intestinal obstruction due to intersigmoid hernia that were diagnosed and treated laparoscopically. The first case was a 42-year-old woman with no surgical history. She was treated conservatively with the insertion of an ileus tube. Although the intestinal obstruction improved temporarily, since it subsequently worsened, laparoscopic surgery was performed, which revealed incarceration of the ileum in the intersigmoid fossa. Although there were no signs of necrosis after intestinal release, partial resection of the small bowel was performed before the hernial orifice was closed due to the evidence of serous damage. The second case was a 53-year-old man with no surgical history. An ileus tube was inserted for intestinal decompression, following which laparoscopic surgery was performed. Operative findings revealed incarceration of the ileum in the intersigmoid fossa, and, since there were no signs of necrosis after intestinal release, the hernial orifice was closed without performing intestinal resection. This condition is a good indication for laparoscopic surgery, given that intestinal necrosis is frequently absent and the operation can usually be completed simply by release of the incarcerated intestine and closure of the hernia orifice. Intersigmoid hernia should be suspected in cases of intestinal obstruction with no surgical history.
