Laparoscopic treatment of a huge mesenteric pseudocyst - case report.

Abstract

Intra-abdominal cysts and pseudocysts are rarely occurring lesions. Their incidence is reported to be 1 per 100 000-250 000 hospitalizations. The lesions’ rarity and their mostly asymptomatic development causes troubles in early recognition and treatment. The patients’ complaints are unspecific and mostly occur when the cysts are enlarged. Sometimes these entities may cause signs of peritoneal irritation and be the reason for immediate operation. It may happen in the event of cyst rupture, torsion, haemorrhages into the lesion or signs of compression of neighbouring structures. Many radiological methods are helpful in revealing intra-abdominal cysts. Unfortunately they cannot accurately distinguish the character of the lesion. The most common surgical procedure of treatment is excision during laparotomy. However, in some cases the laparoscopic approach can be equal to open surgery. This article presents a case of a young woman with a large intra-abdominal pseudocyst treated with laparoscopy.

Mesenteric pseudocyst of the transverse colon: unusual presentation of more common pathology

“…Mesenteric cyst is a rare cystic disease that occurs within the abdominal cavity with a prevalence rate of approximately 1/100 000–1/250 000 among adult hospitalised patients 2. Mesenteric cysts originate from the mesentery or the surrounding area and have no linkage with retroperitoneal organs, they can occur in any area of the mesentery 1.…”

“…According to prior reports, it occurs most frequently in the small bowel mesentery, with an incidence rate of 50–80%, followed by large bowel mesentery with a rate of 15–30%, and retroperitoneal space with a rate of 7–20%. When it occurs in the large bowel, it is more frequent in the right colon 2 3. Although mesenteric cysts have been classified in accordance with embryological and causal standards, they are divided into six groups according to the histological features (box 1).…”

“…Although mesenteric cysts have been classified in accordance with embryological and causal standards, they are divided into six groups according to the histological features (box 1). 2 3 Among these, (non-pancreatic) pseudocysts, though not related to pancreatitis, are histologically similar to pancreatic pseudocysts, and the wall of the cyst is composed of fibrous tissue and characterised by the absence of epithelial lining cells. Mesenteric pseudocysts are rare and only few case reports have been noted until now 1 6 7.…”

“…Mesenteric cyst is a relatively rare tumour arising within the abdominal cavity that originates from the mesentery or the surrounding area and has no linkage with retroperitoneal organs 1 2. Although it may occur in any part of the mesentery, it is located in the mesentery of the small intestine and mesocolon in most cases 2 3.…”

“…Although it may occur in any part of the mesentery, it is located in the mesentery of the small intestine and mesocolon in most cases 2 3. Mesenteric cysts are frequently discovered by chance on ultrasonography or CT because of the absence of symptoms, with occasional discovery when patients report of the symptoms associated with compression or complications of the cysts 1 3–5.…”
