Rare peritoneal bands and recesses: incidental findings in a cadaveric dissection
The patient was a female in her 70s without previous laparotomy who visited our hospital for right lower abdominal pain. Marked small intestinal gas was noted on plain abdominal X-ray radiography. The patient was diagnosed with ileus and admitted. On contrast imaging through an ileus tube inserted for decompression, the small intestine was obstructed in the right lower abdominal region, and emergency laparotomy was performed. A hernial orifice was present on the lateral side of the cecum, and the small intestine was partially incarcerated, based on which a pericecal hernia was diagnosed. Since no circulatory disorder was noted in the incarcerated intestine, only reduction was performed without enterectomy. The hernial orifice was left open, considering that there was no possibility of re-incarceration. The postoperative course was favorable, and the patient was discharged on the 7th hospital day. Since this was a rare pericecal hernia case of internal hernia, we searched for and reviewed cases reported in Japan. This was a very rare case with a hernial orifice located on the lateral side of the cecum, not included in the current classification of pericecal hernia.
