“… 7 Profound hemorrhage of omental lymphangiomas into the abdomen may present as acute abdomen per reports in the literature, necessitating surgical consult and exacerbating the toil of a hospitalization from the perspective of the patient. 8 Treatment options for lymphangioma include surgical removal or sclerotherapy. Options for agents used in sclerotherapy traditionally include doxycycline, with bleomycin emerging as a secondary option.…”

Abdominal lymphangiomas are benign vascular neoplasms of the lymphatic vessels. Most are believed to be congenital, and they rarely present in the abdomen in adults. Omental lymphangiomas, in particular, are especially rare and can masquerade as malignancy, which requires further invasive workup. We report the case of an otherwise healthy man with abdominal discomfort, ascites, and a presentation initially concerning for malignancy. However, imaging and pathologic analyses later elucidated the lesion as an omental lymphangioma requiring different management. Treatment options are either resection or sclerotherapy, and the prognosis is generally excellent.

Lymphangioma is a common pediatric problem. Most of the lymphangiomas occur in head and neck region. Lymphangioma arising from omentum is extremely rare. It is a benign condition butis locally invasive. Symptoms usually arise from its mass effect or complications. Complete excision including removal of all loculi is necessary for cure. We report such a case of omental lymphangiomain a six-year boy.

“…Laparoscopic surgery, including robotic-assisted and laparoscopic-assisted surgery, has become an option for treating ML and OL, but previous reports are sparse with small sample sizes [ 14 – 16 ]. In addition, to our knowledge, no studies have systematically compared the clinical characteristics, surgical management and prognosis of ML and OL.…”

Purpose To compare the clinical characteristics, surgical management and prognosis of mesenteric lymphatic malformations (ML) and omental lymphatic malformations (OL) in children. Methods This retrospective study included 148 ML patients and 53 OL patients who underwent surgical treatment at two centers between January 2016 and December 2022. Details about the patients’ clinical characteristics, cyst characteristics, preoperative complications, surgical methods, and prognosis were retrieved and compared. Results No significant differences in sex ratio, prenatal diagnosis, or age of diagnosis were noted between ML and OL patients. Vomiting was more common in ML patients than in OL patients (46.6% vs. 22.6%, P = 0.002), but OL patients were more likely to be misdiagnosed (35.8% vs. 18.9%, P = 0.012). The size of the cysts in OL patients was significantly larger than that in ML patients (14.0 [4.0–30.0] vs. 10.0 [2.0–50.0] cm, P<0.001), and cysts with turbid fluid were more common in OL patients (38.0% vs. 20.6%, P<0.001). More OL patients than ML patients had preoperative hemorrhage or infection of cysts (41.5% vs. 31.8%, P<0.016). Cyst excision was performed in 137 (92.6%) ML patients and 51 (96.2%) OL patients, and the incidence of postoperative complications was lower (12.6% vs. 4.2%, P = 0.165) among OL patients. The main postoperative complications included adhesive ileus and recurrence of cysts. Additionally, more OL patients than ML patients were treated with laparoscopic surgery (69.8% vs. 39.2%, P<0.001). Conclusions There were differences in clinical characteristics, cyst characteristics and preoperative complications between ML and OL patients. Cyst excision was the most common surgical method that was used to treat both ML and OL patients, and laparoscopic surgery could be a feasible surgical approach for treating OL patients with a good prognosis. Trial registration Retrospectively registered.
