Superior mesenteric artery (SMA) syndrome is a rare cause of abdominal pain, nausea and vomiting that may be undiagnosed in patients presenting to the emergency department (ED). We report a 54-year-old male presenting to a community ED with abdominal pain and the subsequent radiographic findings.The patient’s computed tomgraphy (CT) of the abdomen and pelvis demonstrates many of the hallmark findings consistent with SMA syndrome, including; compression of the duodenum between the abdominal aorta and superior mesenteric artery resulting in intestinal obstruction, dilation of the left renal vein, and gastric distension. Patients diagnosed with SMA syndrome have a characteristically short distance between the superior mesenteric artery and the aorta (usually 2–8 mm) in contrast to healthy patients (10–34 mm). Our patient’s aortomesenteric distance was measured to be approximately 4 mm. Furthermore, the measured angle between the superior mesenteric artery and the aorta is reduced in patients with SMA syndrome from a normal range of 28°–65° to a measurement between 6°–22°. Our patient’s aortomesenteric angle was difficult to measure secondary to poor sagittal reconstructions, but appears to be approximately 30°. Following radiographic evidence suggesting SMA syndrome together with our patient’s constellation of presenting symptoms, a diagnosis of SMA syndrome was made and the patient was admitted to the general surgery service. However, our patient decided to leave against medical advice owing to improvement of his symptoms following the emptying of two liters of gastric contents via nasogastric tube evacuation.

Patient: Female, 84-year-old Final Diagnosis: Diaphragmatic hernia • small bowel obstruction Symptoms: Abdominal pain Medication: — Clinical Procedure: Laparoscopic surgery Specialty: Surgery Objective: Rare disease Background: Pericardio-peritoneal windows are surgically created to treat symptomatic pericardial effusion, usually of oncological origin, to alleviate cardiac tamponade-like symptoms. Common complications include infection, failure to drain the fluid correctly, and arrythmias. There are few published cases of intra-abdominal complications due to these interventions. This report discusses pericardial diaphragmatic incarcerated hernia, which is one such complication. Case Report: We report the case of an 84-year-old woman with advanced non-small cell lung carcinoma, who recently underwent surgery to create a pericardio-peritoneal window to treat a chronic malignant pericardial effusion. The patient presented in our Emergency Department because of abdominal pain with absence of flatus and stool for more than 4 days. Computed tomography scanning confirmed a proximal small-bowel obstruction due to incarcerated small bowel into the pericardial window. Reduction of the hernia was performed laparoscopically. After a bowel viability assessment by indocyanine green angiography, the pericardial window was covered by a noncovered macroporous mesh to avoid recurrence and to allow continuous pericardial fluid drainage. Conclusions: In case of abdominal pain after the creation of a pericardio-peritoneal window, we suggest the prompt use of computed tomography after initial examination. Indeed, although rare, a pericardial diaphragmatic hernia is possible and requires surgical exploration if there is a risk of bowel strangulation. The operation can be done laparoscopically, and the hernia repair should involve the placement of a nonabsorbable and noncovered macroporous mesh. This should prevent hernia recurrence, while also allowing adequate drainage of the pericar-dial effusion.
