Abstract Background Extrahepatic portal vein obstruction (EHPVO) is the most important cause of hematemesis in children. Intrahepatic left portal vein and superior mesenteric vein anastomosis, also known as meso-Rex bypass (MRB), is becoming the gold standard treatment for EHPVO. We analyzed the value of preoperative computed tomography (CT) in determining whether MRB is feasible in children with EHPVO. Results We retrieved data on 76 children with EHPVO (50 male, 26 female; median age, 5.9 years) who underwent MRB (n = 68) or the Warren procedure (n = 8) from 2013 to 2019 and retrospectively analyzed their clinical and CT characteristics. The Rex recess was categorized into four subtypes (types 1–4) depending on its diameter in CT images. Of all 76 children, 7.9% had a history of umbilical catheterization and 1.3% had leukemia. Sixteen patients (20 lesions) had associated malformations. A total of 72.4% of Rex recesses could be measured by CT, and their mean diameter was 3.5 ± 1.8 mm (range 0.6–10.5 mm). A type 1, 2, 3, and 4 Rex recess was present in 9.2%, 53.9%, 11.8%, and 25.0% of patients, respectively. MRB could be performed in patients with types 1, 2, and 3, but those with type 4 required further evaluation. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of CT were 100%, 83.8%, 42.1%, 100%, and 85.5%, respectively. Conclusions Among the four types of Rex recesses on CT angiography, types 1–3 allow for the performance of MRB.

Pancreatic Head Tumor

There have been no reports of ruptured solid pseudopapillary neoplasm (SPN) into adjacent organs. A 22-year-old female was referred to our hospital for treatment of a pancreatic head tumor. Computed tomography (CT) examination at our hospital showed a 5-cm tumor containing air, although CT at a previous hospital revealed an 8-cm tumor without air. Thus, a spontaneous rupture of the tumor into the duodenum was suspected. Subtotal stomach preserving pancreaticoduodenectomy with combined resection of the portal vein was performed. Contrast radiography of resected specimen showed the medium injected into the tumor leaking out from the 2nd portion of the duodenum. Histologically, the patient was diagnosed as SPN. Microscopic invasion to the portal vein and duodenum were also confirmed. She did not experience any postoperative complications and has remained well without any signs of recurrence during 2 years of follow-up. Although there have been 14 studies reporting ruptured SPN, this is the first report of SPN that spontaneously ruptured into the duodenum. An extremely rare case of SPN of the pancreatic head that spontaneously ruptured into the duodenum was reported.
