RESUMO
BACKGROUND: Considering that right paraduodenal hernia is a rare internal hernia with abnormal anatomy and is often encountered during an emergency, surgeons may lack knowledge about it and choose incorrect treatment. Thus, this case report is a helpful complement to the few previously reported cases of right paraduodenal hernia. Additionally, we reviewed all the reported right paraduodenal hernia cases and proposed appropriate surgical strategies according to different anatomical features. CASE PRESENTATION: The case involved a 33-year-old Chinese male patient who was admitted to the hospital due to abdominal pain. The patient was initially diagnosed with small bowel obstruction, and conservative treatment failed. An emergency operation was arranged, during which a diagnosis of right paraduodenal hernia was made instead. After surgery, the patient recovered well without abdominal pain for 2 years. CONCLUSION: Although right paraduodenal hernia accounts only for a small proportion of paraduodenal hernia, its anatomical characteristics can vary considerably. We divided right paraduodenal hernia into three types, with each type requiring a different surgical strategy.

Internal hernias cause 1 percent of intestinal obstructions with aproximately 50 percent of these hernias been paraduodenal hernias. Paraduodenal hernias are the product of a malrotation of the midgut during embryogenesis or a non-fusion of the peritoneal folds. These type of internal hernia are more cornmon in males and on the left side of the abdomen. The usual presentation age is in the 4th decade of life. The clinical presentation of these patients is non specific and varies, ranging from mild dyspepsia to intestinal perforation and septic shock. The radiographic studies of these patients show a dumping of the intestinal loops on the upper quadrant of the abdomen with an image of abdominal compartamentalization. The surgical management of these patients should follow three simple principles. The intestines should be reduced, their perfusion and viability must be verified and the hernia sack entrance should be repaired with interrupted non absorbable sutures.
Las hernias internas causan el 1 por ciento de las obstrucciones intestinales. De estas, aproximadamente la mitad son causadas por hernias paraduodenales. Las hernias paraduodenales son producto de una embriogénesis defectuosa, donde el intestino no rota o los pliegues mesentéricos no se fusionan adecuadamente. Estas hernias son más comunes en el género masculino, del lado izquierdo y por lo general se diagnostican en la cuarta década de la vida. La presentación clínica es inespecífica con manifestaciones que varían desde la dispepsia hasta la perforación intestinal y el choque séptico. Los estudios de imagen muestran el agrupamiento de las asas intestinales en el abdomen superior dando una imagen de compartamentalización de la cavidad abdominal. Para el manejo quirúrgico de estos pacientes se debe reducir el intestino herniado, verificar que este sea viable y posea una adecuada perfusión y reparar el orificio hemiario con material no absorbible.
