PURPOSE: Abdominal cysts of gastrointestinal origin are rare. Their rarity and varied clinical presentations make their pre-operative diagnosis difficult. METHODS: Fourteen patients with histological diagnosis of cysts of gastrointestinal origin admitted between 2009 and 2015 were retrospectively analyzed with respect to age, sex, clinical presentation, diagnostic modality, site and type of cyst, management, outcome and follow-up. RESULTS: The mean age at presentation was 4 years and there were six males and eight females. Abdominal pain was the most common presenting symptom. Five patients had an acute presentation-three had distal ileal mesenteric cysts and two had ileal duplication cyst sharing a common wall with ileum. Six patients presented with chronic abdominal pain and lump—three patients had omental cysts and three had mesenteric cysts—two of these in distal ileum and one in sigmoid colon. Two patients presented with antenatally diagnosed palpable abdominal lump. One had a mesenteric cyst of the ileum and the other had a distal ileal duplication cyst which required excision with resection and anastomosis. One patient had an atypical presentation. He was a known case of sickle cell trait and had presented with vague abdominal pain, recurrent cough and multiple episodes of haemoptysis over a period of one year. At laparotomy, gastric duplication cyst was found which was excised completely. Histopathology confirmed the diagnosis. CONCLUSION: Cysts of gastrointestinal origin are rare and have varied presentation. Surgical excision is the mainstay of treatment. The results and prognosis are good.

Mesenteric cysts are rare intra-abdominal lesions occurring during childhood, which were first described in 1507. Cases of mesenteric cysts have been continuously reported, but these cases were very small in number. They are often asymptomatic and incidentally found while patients are undergoing work-up or receiving treatment for other conditions such as appendicitis, small-bowel obstruction, or diverticulitis; however, patients may still have lower abdominal pain and symptoms that are frequently associated with other abdominal conditions. The symptoms are variable and non-specific, including pain (82%), nausea and vomiting (45%), constipation (27%), and diarrhea (6%). An abdominal mass may be palpable in up to 61% of patients. We are to report the clinical course and literature of a child with mesenteric cysts who complained of acute abdominal pain, distension, and vomiting and were surgically treated after being diagnosed with mesenteric cysts based on radiological examination.

Mesenteric pseudocyst is rare. This term is used to describe the abdominal cystic mass, without the origin of abdominal organ. We presented a case of mesenteric pseudocyst of the small bowel in a 70-year-old man. Esophago-gastro-duodenoscopy showed a 3.5 cm sized excavated lesion on the posterior wall of angle. Endocopic biopsy confirmed a histologic diagnosis of the poorly differentiated adenocarcinoma, which includes the signet ring cell component. Abdominal computed tomography scan showed a focal mucosal enhancement in the posterior wall of angle of the stomach, a 2.4 cm sized enhancing mass on the distal small bowel loop, without distant metastases or ascites in rectal shelf, and multiple gallbladder stones. The patient underwent subtotal gastrectomy with gastroduodenostomy, segmental resection of the small bowel, and cholecystectomy. The final pathological diagnosis was mesenteric pseudocyst. This is the first case report describing incidentally detected mesenteric pseudocyst of the small bowel in gastric cancer patients.

PURPOSE: Intra-abdominal cystic masses originating from the retroperitoneum, mesentery or omentum are very rare and mostly benign tumors, but sometimes present as a complicated cyst encasing the major organs. METHODS: We analyzed the clinical findings, histologic diagnosis, and surgical outcomes in children who underwent operation for retroperitoneal, omental, and mesenteric cyst from 1998 to 2010, retrospectively. RESULTS: Twenty-three patients (male, 12; female, 11) underwent the operation at a median age of 46 months (range, 9 days to 16 years). Among them, 17 cysts presented one or two symptoms such as abdominal mass, abdominal pain or abdominal distension. The median duration of symptoms was 7 days (range, 1 day to 365 days). Five were detected prenatally. Ten cysts were found in retroperitoneum, 8 in the omentum and 5 in the mesentery. The median diameter was 13 cm (range, 3 to 30 cm). Twenty cysts were completely removed. Five mesenteric cysts required bowel resection and anastomosis. Three of retroperitoneal cysts were impossible to complete excise because of location and extensiveness. Pathologically, 20 cysts were lymphangioma and 3 were pseudocyst. The morbidity was one of adhesive ileus and the mortality was one who had extensive retroperitoneal cyst with mesenteric cyst. He died from sepsis. During follow-up period, there was no recurrence. CONCLUSION: Preoperative diagnosis and localization for these cysts are very difficult. Complete excision was possible in almost all cases despite the size, bringing a favorable outcome. The possibility of this disease entity should be considered as the cause of acute abdomen.

A 48 year old woman was diagnosed with a huge cystic mass in her abdominal cavity. She complained of significant abdominal discomfort due to the mass. The abdominal computed tomography revealed a giant multi-lobulated mass, measuring 26x12 cm in size, adjacent to the lesser curvature of the stomach. In the operation field, the mass was found to originate from the lesser omentum, including the right and left gastric vessels and the vagus nerves, and to invade the lesser curvature of the stomach. For curative resection, distal subtotal gastrectomy with mass excision followed by gastroduodenostomy were performed. This mass was pathologically diagnosed to be a mesenteric cystic lymphangioma; in fact, the largest ever reported. The patient had no complications during the postoperative period and was discharged from the hospital on the seventh day after surgery.

Mesenteric cysts are rare intra-abdominal tumors. Mesenteric cysts are usually asymptomatic and are incidentally detected during physical or radiological examination. Although uncommon, complications such as infection, bleeding, torsion, rupture and intestinal obstruction cause an acute abdomen. Spontaneous infection is a very rare complication. We present a case of infected mesenteric cysts in the ascending colon, which caused an acute abdomen. A 26-year-old woman was admitted to our hospital with acute abdominal pain. She had a painful mass in the right abdomen on physical examination. Abdominal computed tomography showed a hypodense cystic mass with septation at the mesenteric region of the ascending colon. A laparotomy revealed two cystic tumors at the mesenteric region of the ascending colon. She underwent a right hemicolectomy. The two cysts were filled with a yellowish turbid fluid. The walls of both two cysts were lined with a thin fibrotic membrane without any epithelial cell. They were diagnosed as psuedocysts with E. coli infection. Mesenferic cysts may cause life-threatening complications. Mesenteric cyst, even if it is asymptomatic and was diagnosed incidentally, should be removed completely.

PURPOSE: Ultrasonography (US) is widely used as a screening test in patients with abdominal pain (AP). We investigated the usefulness of US by a pediatrician in children with AP. METHODS: We retrospectively analysed the medical records of children with AP who undertook US from December, 2008 to July, 2010. RESULTS: A total of 628 patients (325 male, 303 female) were enrolled in this study. The mean age of patients was 8.08+/-4.61 years. Duration of AP was acute in 427 and chronic in 201 patients. Localization of AP was diffuse (36.9%), periumbilical (24.4%), epigastric (21.0%), and right lower quadrant (8.1%). On the examination, there were no abnormal findings in 327 patients (52.1%). Abnormal ultrasonographic findings were mesenteric lymphadenitis (27.1%), intestinal mural thickening (10.0%), intussusception (3.0%), appendicitis (2.6%), choledochal cyst (1.6%), and pancreatitis (0.3%). We performed additional imaging studies such as computed tomography (CT) or magnetic resonance imaging (MRI) in 39 patients who showed obscure findings on the US. In 33 patients (84.6%), the same results were obtained from CT or MRI. Two cases of appendicitis, one case of pancreatitis and one case of Henoch-Shonlein purpura were diagnosed by the CT examination. However, there were two cases of appendicitis diagnosed by US thathad no evidence of appendicitis on the CT. Diagnostic accuracy of initial US in children with abdominal pain was 99.4%. CONCLUSION: US by a pediatrician as a screening test in children with AP provides a rapid and accurate diagnostic indication and has non-invasive and radiation-free advantages.

An intra-abdominal cystic lymphangioma is a benign neoplasm that rarely occurs within the abdominal cavity. Intra-abdominal cystic lymphangioma is treated by a resection performed through a radical procedure. We report a case of a 37-year-old woman who had an asymptomatic mesenteric cyst that was discovered incidentally during a routine physical check-up. Treatment was completed without complications using a laparoscope.

Mesenteric cysts are uncommon, and they are histopathologically classified as pseudocyst, mesothelial cyst, lymphangioma and omental cyst. We report a case of a 27-year-old female with a huge cystic mass arising from greater omentum. Patient complained the symptoms of abdominal distention due to massive ascites and intermittent pelvic discomfort. The diagnostic examinations including ultrasonography and computed tomography were performed and identified a huge, intraabdominal cyst. Laparoscopic resection of cyst was done with no clinical and symptomatic evidence of adverse event till 12 months. The diagnostic role of sonography and CT in ascites with unknown etiology is emphasized. Minimal invasive surgery showed comparable result to open exploration.
