Transmesocolic internal herniation: a rare case of small bowel obstruction, "the Marrakesh hernia".

Internal hernias, including paraduodenal (traditionally the most common), pericecal, foramen of Winslow, and intersigmoid hernias, account for approximately 0.5-5.8% of all cases of intestinal obstruction and are associated with a high mortality rate, exceeding 50% in some series. We report an extremely rare case of an internal abdominal hernia, through the right mesocolon, in a young woman with a right colon with no peritoneal fixation. This hernia was revealing by abdominal pain, nausea, and vomiting. The diagnosis of internal hernia was suggested by computed tomography (CT), but the exact type of internal hernia was confirmed by surgical exploration. The postoperative course was uneventful and the patient fully recovered after 3 days. The patient is free from symptoms and from recurrence, after 12 months of follow-up.

[Sigmoid volvulus, a rare complication of pregnancy]. / Volvulus du sigmoïde, une complication rare de la grossesse.

Sigmoid volvulus complicating pregnancy is a rare complication with less than 80 cases reported in literature. We report the case of a young pregnant woman, admitted for sigmoid volvulus. The sigmoid volvulus was resected and Bouilly-Volkmann's colostomy was performed. According to this case and depending on the literature, the authors discuss the diagnostic and therapeutic modalities proposed for this rare entity.
