RESUMO
BACKGROUND: Portal vein thrombosis is a rare and a potentially lethal complication of Laparoscopic sleeve gastrectomy. In this series, we describe the presentation, treatment, and outcome of 5 cases of PMVT post-laparoscopic sleeve gastrectomy (LSG) treated successfully at our hospital. CASE REPORT: Five patients presented to our emergency department with diffuse abdominal pain associated with anorexia, nausea and vomiting after laparoscopic sleeve gastrectomy (LSG). Computed tomography (CT) scan showed evidence of portal, mesenteric and splenic vein thrombosis and small bowel ischemia in three patients. Two patients were treated only with anticoagulant and the other three patients were treated with surgery in the form of diagnostic laparoscopy converted to laparotomy with Small bowel resection. CONCLUSION: Portal and mesenteric venous thrombosis after laparoscopic sleeve gastrectomy is an unusual complication but it has life threatening consequences if it is not diagnosed early and treated adequately. The patients with porto-mesenteric venous thrombosis (PMVT) usually present themselves with vague abdominal symptoms. As so, the physicians should have high index of suspicion to recommend computed tomography (CT) abdomen to confirm diagnosis and start adequate treatment.
RESUMO
BACKGROUND Duodenal compression between the superior mesenteric vessels and aorta or its branches is a rare disease in which the angle between the superior mesenteric vessels and aorta becomes acute, resulting in duodenal obstruction. Reduction in retroperitoneal fat due to several debilitating conditions is considered to be the cause of the decreased angle between the 2 vessels. Nutcracker phenomenon is the asymptomatic compression of the left renal vein (LRV) between the aorta and the superior mesenteric artery. CASE REPORT We report the case of a 33-year-old man who presented with postprandial abdominal pain, mainly at the epigastric region, colicky in nature, without radiation, accompanied by nausea, postprandial vomiting, and loss of weight. Computed tomography (CT) of the abdomen showed duodenal compression between the SMV and the right common iliac artery, which has never been reported before. Laparoscopic duodenojejunostomy was performed. CONCLUSIONS Vascular compression of the duodenum presents with manifestations of proximal small bowel obstruction, which may have chronic, intermittent, or acute symptoms. Diagnosis is difficult due to the lack of knowledge of this rare disorder. Most of these symptoms can be present in other diseases, and symptoms sometimes do not correspond with imaging findings. Therefore, for a better outcome, the clinician should have a high index of suspicion and should be able to exclude other causes with similar manifestations.
