Mesenteric cyst presenting with acute abdomen pain and bowel obstruction: Case report and brief literature review

Mesenteric cysts were first described in 1507 and since then remain as a rare intraabdominal pathology. The etiology of this kind of tumor is still unclear and the classification remains controversial. They are usually asymptomatic, but can also cause acute abdominal pain and sometimes need emergency surgical approach. Clinical history, physical exam and complementary tests do not always provide diagnosis, which in many cases is made after surgery. Surgical management with complete excision of the cyst is the gold standard treatment. Laparoscopy technique should be preferred whenever is possible. The knowledge of these rare tumors is important for considering the correct approach. The goals of this article is to describe a case report of mesenteric cyst presented with acute abdominal pain at the emergency and do a brief literature review about this entity.

•

Mesenteric cysts are a rare cause of intraabdominal mass.

•

Mesenteric cyst should always be considered it whenever the patient has an intraabdominal palpable mass.

•

Computed tomography of the abdomen can help find the diagnosis in many cases.

•

Even when mesenteric cyst is diagnosed incidentally, surgery should always be indicated in order to prevent complications.

•

Surgery is the treatment of choice and recurrence rate is low when the correct treatment is performed.

Cystic Lymphangioma of the Greater Omentum: A Case of Partial Spontaneous Regression and Review of the Literature

Introduction. Omental cysts are a part of cystic lymphangiomas and are benign proliferations of ectopic lymphatics without a communication with the normal lymphatic system. They commonly involve the neck in the pediatric population and are uncommon at other sites and occur rarely in adults. Case Presentation. A 42-year-old female with complaints of vague lower abdominal pain for 8 months presented with a soft, nontender swelling of size 22 × 18 cm in the hypogastrium and umbilical region. Computerized tomography (CT) of the abdomen showed a peripherally enhancing hypodense cystic lesion of size 19 × 14 × 12 cm perhaps arising from the mesentery. The cyst had spontaneously reduced in size by about 70% over the next 4 months. During surgery, the cyst of size 10 × 9 × 8 cm was present in the greater omentum. Excision was done, and histopathology was suggestive of cystic lymphangioma. Discussion. Cystic lymphangiomas have an incidence of 1/20000 at infancy and 1/100000 to 1/250000 of hospital admissions in adults, and the female-to-male ratio is 2 : 1. In adults, they are found in the age group between 40 and 70 years. Spontaneous regression of omental cysts is very rare and presumably from increased pressure in cysts overcoming incomplete obstructions or by establishment of alternative routes of drainage.

Single-port laparoscopic-assisted resection for a large abdominal cystic lymphangioma: a case report

Background

We report the case of a young woman with a large abdominal cystic lymphangioma that was successfully resected using single-port laparoscopic-assisted cystectomy. This avoided the need for a large surgical incision, as would result during conventional laparotomy.

Case presentation

A 17-year-old young woman was admitted to our hospital complaining of abdominal pain that had persisted for 3 days. Computed tomography revealed a 10 × 10 × 10-cm low-density area in the mid-abdomen, and magnetic resonance imaging showed a large abdominal cystic lesion. A mesenteric cyst was suspected, and single-port laparoscopic-assisted resection was performed. The cyst fluid was aspirated using a tissue adhesive, a suction tube with negative pressure, and a 16-gage over-the-needle catheter and syringe. The tumor size was reduced without any spillage of cyst fluid into the abdominal cavity. Then, the shrunken cystic tumor was successfully removed via the small wound and resected outside the abdomen. Pathological findings revealed an abdominal cystic lymphangioma derived from the greater omentum.

Conclusions

Our procedure was easy to perform and required no special materials. Therefore, it could be applied to various cases, such as for abdominal cystic diseases.
