Left paramesocolic hernia with retroperitoneal incarceration of jejunum

We present a case left paramesocolic hernia and review the literature. The patients was a 14 years old male and had suffered periods of relapses into abdominal pain from the age of three. When for years old he was operated on using the Nisses technique. Also a laparoscopy had already been performed on this same patient when he was 13 years old, without discovering any pathological conditions. In a new upper gastrointestinal serie, realized one year later, a retroperitoneal incarceration and a paraduodenal loop of jejunum was observed, which obstructed, partially the second part of the duodenum. We have not found the anatomical characteristics of this case in any previous report. In the ample literature pressured, it was confirmed that almost all the clinical cases, previously published had suffered a relapse abdominal pain crisis, diagnosed in advanced states and in/or emergency situations. This produces a mortality rate higher than 20% and or irreparable digestive damage. In cases involving paraduodenal hernias, there exists a low rate of diagnostic suspicion. These delays and diagnostic errors cause irreparable damage. In those patients who suffer relapses into abdominal pain syndrome, one should always include the differential diagnosis of PMH, applying a complete gastrointestinal serie or a CT-Scan with contrast.
