Ao observar o peritonio do tamandua bandeira, dois aspectos chamam a atencao: o primeiro e a nao aderencia dos colons a parede dorsal, conforme ocorre em outros vertebrados (SIQUEIRA & LAZARO-da-SILVA, 2003; MOORE & PERSAUD, 2008; PEREZ et al., 2008); e o segundo e a fixacao dos intestinos grosso e delgado a mesma macromembrana, ou seja, uma unica raiz serosa vertical prende cranialmente o mesenterio e caudalmente o mesocolon. Embora a literatura faca referencia sobre a evolucao do mesenterio (GRASSE, 1965), esta nao esclarece que aspectos levaram esse animal a exibir esse modelo de peritonio e dos vasos que nele transitam.
This type of tumor rarely arises in extrapancreatic sites, such as the retroperitoneum, mesocolon, and liver.
Our proposal is to perform an anchorage of the jejunum to peritoneal sheet of the descending mesocolon that involves the parietal fixing of the probe of the jejunostomy.
A Roux-en-Y loop of the jejunum is brought through a rent in the transverse mesocolon, the duodenum is transected, and the duodenal stump is oversewn.
In one patient with huge retroperitoneal cyst, it was arising from the pelvis and occupying the whole sigmoid mesocolon and extending into the abdomen getting blood supply from inferior mesenteric artery, hence sigmoid colon resection was inevitable.
Lymphangiomas in the peritoneal cavity are extremely rare occurring most commonly in the mesentery, followed by the omentum, mesocolon, and retroperitoneum.
The other end of the band was attached to the ascending colon in four cases, the Treitz' ligament in two cases, and the right lobe of the liver in two children.3 Lin et al8 have reported a band extending from the iliac fossa to the sigmoid mesocolon, while Itagaki et al9 reported the presence of a jejuno-jejuno congenital band.10
(4) Clues suggesting the presence of a pancreatic injury include a lesser sac fluid collection, retroperitoneal bile-staining, and crepitus or haematoma overlying the pancreas at the base of the transverse mesocolon or visible through the gastrohepatic ligament.
The anastomosed jejunal loop, called the Roux limb, is placed retrocolic through an aperture formed in, or in front of, the transverse mesocolon. Finally, a jejunojejunostomy is created 100 cm to 150 cm distal from the original gastrojejunostomy.
A presenca de massas no mesocolon pode provocar distensao do intestino e este em contato com o flanco esquerdo pode produzir sons e sinais similares aos encontrados no deslocamento de abomaso e, dessa forma, a palpacao retal e um exame util na diferenciacao dessas duas condicoes (BRIDGE & SPRATLING, 1962).
As a result, the small bowel becomes trapped in a hernial sac formed by the peritoneum behind the colonic mesentery, where the cecum and ascending colon rotate anteriorly, while in left PDH, the small bowel invaginates into an avascular segment of the left mesocolon and is entrapped between the mesocolon and the posterior abdominal wall, forming the anterior wall of the hernia sac [4, 37].
