Background The portal vein is occasionally invaded by advanced malignant tumors in the pancreatic head region. However, pancreatic cancer rarely has portal vein tumor thrombi. We report a case of pancreatic cancer with a massive portal vein tumor thrombus undergoing pancreatoduodenectomy with combined resection of the portal vein. Case presentation A 71-year-old man visited a clinic with complaints of abdominal discomfort and vomiting. Gastroscopy showed a massive tumor in the duodenum. He was referred to our hospital for further examinations and treatment. The CT showed a low-density tumor with a maximum diameter of 10 cm located on the pancreas head. A tumor widely invaded the duodenum and had a 6-cm portal vein tumor thrombus. MRCP did not show obvious stenosis of the pancreatic duct due to tumor invasion. There were no findings suggesting distant metastases. Biopsy of the duodenum revealed adenocarcinoma. He was diagnosed with primary pancreatic cancer or duodenal cancer with portal vein tumor thrombus and underwent pancreatoduodectomy with resection and reconstruction of the portal vein. He suffered no postoperative complications and was discharged 2 months after surgery. The final histopathological diagnosis was pancreatic colloid carcinoma. He received adjuvant chemotherapy, but died 16 months after surgery. Conclusions Colloid carcinoma of the pancreas is rare, and pancreatic carcinoma seldom forms a portal vein tumor thrombus. We experienced a very rare case of pancreatic colloid carcinoma with portal vein tumor thrombus and performed radical resection of the pancreas and portal vein.

A 34-year-old man presented with a mass in the upper abdomen; physical examination revealed an epigastric bulge and tenderness over the bulge. Abdominal computed tomography (CT) revealed linea alba hernia. Because the hernia was tender to palpation and was not reducible manually, elective laparoscopic surgery was performed. During the operation, a hernia orifice was found in the midline of the upper abdomen, with herniation of the omentum through the orifice. The herniated omentum was reduced laparoscopically, and after removing the incarceration, the hernia orifice was repaired with an IPOM (intraperitoneal onlay mesh). Laparoscopic surgery has been performed increasingly frequently in recent years for linea alba hernia, but evidence for the short- and long-term outcomes remains elusive. However, in light of the low recurrence rate, large number of cases, and cosmetic acceptability, expectations for laparoscopic surgery are high. Herein, we report a case of linea alba hernia, which was repaired by laparoscopic surgery using Bard Ventralight ST with Echo2.
