Abstract

Introduction: Falciform/ round liver´s ligament defects are uncommon, have various clinical features that they can cause, and are generally diagnosed intraoperatively. Currently, abdominal tomography is performed routinely in the emergency room, it can help in the preoperative diagnosis and guide the therapeutic attitude to be performed, but currently, there are no characteristic tomographic data of this pathology. There are few published cases in the literature, and these were generally diagnosed at a late stage and were mostly among adults.

Presentation of case: We present a 45-year-old female patient who presented with acute abdominal pain to the emergency room. The patient had never undergone abdominal surgery.

Discussion: On diagnostic laparoscopy found the transverse colon and small intestine (duodenum) crossing a foramen in the liver's round/ falciform ligament. The obstruction was resolved by dividing part of the ligament without intestinal resection.

Conclusion: All structural entrapments caused by the falciform/ round liver's ligament are produced by an abnormal fixation process of the anterior peritoneum in its embryonic stage. The most common clinical presentation associated with these defects is intestinal obstruction. We propose the term "inclusion in the falciform/ round liver's ligament " as a concept to encompass these clinical presentations of pain, occlusion, or other digestive pathology, which are accompanied by an abnormal fixation of structures of the digestive system towards the falciform/ round liver's ligament. An accurate diagnosis is only possible under direct vision in surgery, where, in addition to being diagnostic, it is therapeutic.
