Mesenteric vein thrombosis after laparoscopic sleeve gastrectomy. A case report

Background: Mesenteric thrombosis is rare entity, but it has a high morbimortality in patients being submitted to a weight loss surgery. Case Report: A 40-year-old patient being submitted, three weeks before, to sleeve gastrectomy, with a history of morbid obesity, obstructive sleep apnea, pulmonary arterial hypertension, among others. The peculiar symptom was the abdominal pain of a 6-hour duration. Mesenteric vein thrombosis was classified as secondary, and a bowel resection of the affected segment was necessary but there was immediate bowel restitution. The patient develops acute renal failure which leads to substitutive therapy of the renal function with Prism machine. The patient evolves without any complication. The patient loses 50% of weight after 2 months of surgery. Discussion: Mesenteric vein thrombosis is a rare entity with vague symptomatology. The patient history, diagnostic suspicion and image studies are the most important factors which lead to diagnosis, which is difficult to diagnose before surgery. Surgery with resection of the affected segment means acceptable results. Conclusions: The high suspicion index, the diagnosis and the early treatment in a patient with mesenteric thrombosis submitted to a weight loss procedure improve the life expectancy of a patient with these features. However, more studies, for this kind of population with this disease, are required. Keywords: sleeve gastrectomy, mesenteric vein thrombosis.
