Experience of management of abdominal cysts

Benign intra-abdominal cystic masses in children are rare and they have diverse etiopathogenesis, clinical presentation. The present study highlights the experience in the management of benign intra-abdominal cysts pertaining to the diverse etiologies associated with these lesions. The medical records of our hospital between November 2016 to November 2019 were retrospectively reviewed. Patients with cystic abdominal masses were studied with respect to less different clinical presentations, localization of masses, diagnostic tests, surgical aapproaches, histopathological examinations and outcome. Out of the 55 cases, most common lesion was a choledochal cyst. Miscellaneous diagnosis includes an omental cyst, urachal cyst and a pedunculated bile duct cyst. All the cystic lesions of the abdomen need to be considered as close differentials in clinical practice due to the common presentations and similar symptoms produced by these lesions. All the lesions were managed by exploratory laparotomy except two ovarian cysts which were managed with laparoscopic approach.

Laparoscopic excision of large omental cyst at department of pediatric surgery in Sanglah general hospital, Bali, Indonesia

Omental cyst is rare. All conditions most likely being of congenital or benign neoplastic lymphatic origin. Patients with Omental cysts usually present with abdominal distention and a painless abdominal mass. The most common physical finding of an omental cyst is a freely movable abdominal mass. The diagnostic procedure include CT scans. Complete excision by open or laparoscopically of the cysts is considered as the treatment of choice. Recurrence and malignant deterioration of omental cysts are rare. A case report of a large omental cyst which had been laparoscopically-treated using morcellator. Laparoscopic morcellation  is a technique used in gynecological surgeries such as hysterectomy and myomectomy to remove uteri and uterine fibroids (leiomyomas) through a small abdominal incision. Authors present a case of 3 year old female with pre-operative assessment tumor intra-abdominal suspect abdominal cyst. Subsequently, laparoscopic resection of omental cyst with morcellator was performed. The histopathological report was omental cyst. Omental cysts are rare, but can be shown to have atypical abdominal symptoms and radiologic findings, so clinicians must keep in mind that omental cysts causing abdominal symptoms can be misdiagnosed as simple ovarian cysts of inflammation. Omental cysts can be removed safety laparoscopically with morcellator without bowel or vessel injury.

The surgical experience for retroperitoneal, mesenteric and omental cyst in children / 대한외과학회지

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.

Omental myxoid hamartomas - A case report with review of literature.

Omental mesentric myxoid hamartomas are benign infantile lesions, however they may simulate a malignant tumour both clinically and pathologically. Here, we report the case of an omental myxoid hamartoma in a 10-months old infant which was per operatively suspected to be a malignant retroperitoneal tumour, due to adhesions with the surrounding structures as well as the presence of satellite nodules.

Extra-gastric Cyst Lesions Mimicking Gastric Submucosal Tumor

Gastric cancer remains still the most frequent type of cancer despite its declining incidence in Korea. As a result of the health promotion policy of the Korean government and increase in concern for individuals' health, screening endoscopy for detecting early gastric cancer and general physical exams have become widespread. Thereby, the incidental detection of gastric submucosal tumors (SMTs) are now occasionally diagnosed by screening endoscopy. Since endoscopic examination gives little information on SMTs, a variety of studies have been conducted to determine the etiology of SMTs and to distinguish them from extra-luminal compressive lesions. Here, we report one clinical case of cavernous hemangioma on the left lateral section of the liver and one case of omental cyst, which was preoperatively mistaken as gastric SMT.

A Case of Congenital Omental Cyst / 대한주산의학회잡지

Omental cyst is a rare disease and its accurate time and cause of outbreak has not been reported. This disease is known as can be afflicted with postnatally and in case of being afflicted with pre-natally the abdominal cavity and thoracic organ of fetus are oppressed due to fetal abdominal distention leading to fetal death caused by organ dysgenesis. No medical report has yet been published on congenital omental cyst of fetus. This study was conducted on a case of congenital omental cyst of fetus we have experienced in a mother with 16weeks of gestational period and the result is hereby reported along with literally documents.

Omental Cyst

An omental cyst is an uncommon intra-abdominal tumor. The pathogenesis of omental cysts are unknown, as the majority are asymptomatic and if found at all are discovered incidentally during abdominal exploration or radiologic examination. A correct preoperative diagnosis of an omental cyst is very difficult as the information provided by CT and ultrasound imaging is often insufficient to support a differential diagnosis. However, with the increasing availability of ultrasound and CT, preoperative diagnoses of omental cysts are being made more frequently. An exception to this occurs in children, in whom abdominal pain secondary to the cyst may be dominant, necessitating surgical intervention. The most common symptoms and physical findings are abdominal pain and a smooth, non-tender, mobile, palpable mass. Recently, we encountered a case of an omental cyst in a surgically removed omentum. This case is reported with a review of the literature.

Mesenteric and Omental Cysts in Children

Mesenteric and omental cysts are rare intra-abdominal lesions in childhood, and may present various clinical features such as an asymptomatic mass or an acute abdomen. Therefore, these entities are frequently misdiagnosed preoperatively or are found only incidentally at operation for other conditions. We analyzed our experiences of 19 cases in a 19 year period from 1981 to 1999, at College of Medicine, Catholic University of Korea. There were 12 boys and 7 girls with a mean age of 4.8 years (range, 3 days to 15 years). Common presenting symptoms were abdominal pain (47%), abdominal distension (31%), abdominal mass (24%), vomiting (15%) and fever (10%). Ultrasonography was the most preferred method of diagnosis. Other diagnostic modalities include CT, MRI, and abdominal ascites tapping in selected patients. Location of the mesenteric cysts was small bowel mesentery in nine, the right mesocolon and retroperitoneum in one, the left mesocolon in one, and the jejunum, sigmoid-colon mesentery in one. Most of the patients underwent cyst excision, but six patients required concomitant bowel resection for complete removal of the lesions, and two patients underwent unroofing and simple aspiration respectively. There was one mortality case due to sepsis.

Mesenteric and Omental Cysts in Infancy and Childhood

Mesenteric and omental cysts are rare lesions of childhood. These cysts are similar to cystic hygromas in other parts of the body morphologically and pathologically. From 1980 to 1997, 8 children were diagnosed and treated for mesenteric or omental cysts. Their ages ranged from 18 days to 6 years. There were 5 boys and 3 girls. The main presenting symptom was abdominal pain. Operative procedures were complete cysts excision, complete excision with intestinal resection, or complete excision with intestinal resection and colostomy. Accurate preoperative diagnosis was possible with the current ultrasonographic imaging techniques. Complete excision of the lesion was possible in all patients and resulted in an excellent outcome.

Von Hippel-Lindau Disease Manifestating as Recurrent Cerebellar Hemangioblastoma: A Case Report

Cerebellar hemangioblastoma comprises 2% of all brain tumors and 7% 10% of all posterior fossa tumors. It can arise in isolation("sporadic cases") or as a major manifestation of von Hippel-Lindau(VHL) disease, a well known autosomal dominant inherited tumor syndrome. Only 5-30% of these tumors are due to VHL disease. However, cerebellar hemangioblastoma occurs in younger patients, is often multiple and recurrent, and has a poorer prognosis than sporadic cases. We present a case of a 26-year-old woman with a right cerebellar hemangioblastoma, which recurred from a left cerebellar hemangioblastoma resected four years previously. Further evaluation established the diagnosis of VHL disease by demonstrating a cystadenoma in the pancreas and an omental cyst. Recently, the von Hippel-Lindau disease gene has been identified as a tumor suppressor gene and has been mapped to the short arm of chromosome 3(3p 25-26). Its absence or a defect in its structure is responsible for predisposition to the disease.

Congenital Omental Cyst Associated with Hydrops Fetalis: An autopsy case

Omental cyst is benign unilocular or multilocular endothelium-lined cyst that contains either chyle or serous fluid. They are uncommon yet interesting intraabdominal masses that may be difficult to diagnose clinically and often are missed on abdominal palpation. The etiology of this lesion has been subject to much discussion in the literature over the years with the principal debate centering around the question of whether or not this lesion is congenital. It is now recongnized that there is no single etiologic mechanism involved in the development of this lesion. Recently we have experienced an autopsy case of omental cyst occurring in a male fetus. Pregnancy was artificially interrupted at 28 weeks gestation due to suspicious mesenteric cyst or fetal ascites on ultrasonography. Postmortem examination showed hydrops fetalis, hypoplasia of the lungs, ad multifocal calcifications of myocardium. There was an omental cyst in the greater omentum which was 7x3 cm in size, unilocular and containing clear, straw-colored fluid and proteinacious core without evidence of bleeding or calcifications. Microscopic examination of this cyst showed cuboidal or flattened mesothelial lining cells and underlying loose fibrovascular connective tissue with discrete lymphocytic collections. Rarity and interest on the pathogenesis made us redport this case.
