Cause: the child frolicking hit 8cm tumor Anhui Xiaohui is an elementary school 5 grade students. A month ago Xiaohui and his classmates chase playful, accidentally hit the left side of the waist, then the pain sat on the ground, the afternoon class abdomen has been uncomfortable, the occurrence of uncontrollable vomiting symptoms. The local hospital ultrasound showed a shadow on the left side of the abdomen, suspected of internal bleeding, abdominal CT showed that the tail of the pancreatic body has an occupation, the mass has reached 8cm large, but the routine biochemical examination and even tumor marker test is mostly negative. After two weeks of hospitalization and anti-inflammatory treatment, the mass was still there and did not get smaller. Diagnosis: Pancreatic Pseudopapillary Tumor After reviewing a series of examination reports and films of Xiaohui, and carefully inquiring about Xiaohui’s physical symptoms, Director Qian made a diagnosis that the occupying mass at the tail of Xiaohui’s pancreatic head was a pancreatic Pseudopapillary Tumor. Director Qian told Xiaohui’s mother that pancreatic solid pseudopapillary tumor is a kind of pancreatic tumor, which is characterized by no specific clinical manifestations and is very easy to be misdiagnosed, and it is a kind of pancreatic tumor which is very special and rare, and this kind of tumor is insensitive to radiotherapy, so surgical resection is the most effective method. Surgical Treatment: Successful Splenic Preservation and Tumor Resection Soon after reaching a consensus with Xiaohui’s parents, Director Qian arranged the surgery for Xiaohui. During the surgery, Dr. Qian found that the tumor had already invaded and encapsulated the arteries and veins of the spleen, and the left branch of the middle colonic artery and the duodenal mesentery were also tightly adhered to the tumor periphery, making surgical excision difficult. Considering the young age of Xiao Hui, he tried to preserve the normal function of her organs as much as possible. Adhering to this principle, Director Qian successfully removed the tumor and preserved the spleen with his rich clinical experience and excellent skills. After the surgery, Xiao Hui recovered well and has continued to go to school. Knowledge linkPancreatic solid pseudopapillary tumor is a very rare pancreatic tumor, accounting for only 0.17%~2.7% of pancreatic tumors. Its lesion is of unknown origin, but it is slow-growing and occurs in young women. Most patients are asymptomatic, so that once detected, the tumor is already large in size. Huge tumors often compress the intestinal tube causing intestinal obstruction and squeeze the stomach to produce epigastric distension and discomfort. Director Qian reminded parents that once they find their children claiming abdominal and stomach discomfort, even if the symptoms are not very obvious, they should consult doctor in time to avoid delaying the best treatment time.
