Aim. Study of anatomical variations of the pancreatic neck blood supply, which may affect the results of pancreaticoduodenectomy.Material and methods. Anatomic characteristics of arterial blood supply of pancreas were studied in 42 autopsied cases, who died from diseases not associated with abdominal organs failure. Clinical part of our study included 62 patients. Arterial anatomy was examined during early arterial phase of computer tomography. Options of the origin of the dorsa pancreatic artery were noted. All patients had “soft” pancreas confirmed by morphological examination and computer tomography. Main group included 20 patients. Dissection of the pancreas during pancreatoduodenectomy in this group were performed 10–15 mm left of portal vein confluence. Control (retrospective) group included 42 patients performed standard procedure, when pancreas was dissected above the portal vein confluence.Results. It was found that the neck of pancreas was supplied from dorsal pancreatic artery, found in all specimens. In 76% of cases it was a branch of splenic artery, in other cases – a branch of superior mesenteric artery. CT scan revealed the dorsal pancreatic artery in 54 (87.1%) people, in 8 patients the artery could not be identified. The dorsal pancreatic artery was a branch of the splenic artery in 64.8% of cases. In other cases it was a branch of the superior mesenteric artery, common hepatic artery, gastroduodenal artery and middle colon artery. If the dorsal pancreatic artery was a branch of the superior mesenteric, common hepatic, gastroduodenal artery, it was transected during lymphadenectomy. This led to higher frequency of postoperative pancreatic fistula.Conclusion. Localization of dorsal pancreatic artery must be taken into account during the pancreatoduodenectomy. That allows to decrease probability of postoperative pancreatic fistula.

Inflammatory myofibroblastic tumor (IMT) is a rare disease of unknown etiology. It usually occurs in abdominal soft tissues and lung, and is extremely rare in the pancreas. IMT can occur in any part of a person at any age, however, it mostly affects children and young people. Its clinical manifestations are atypical, imaging examinations are not specific, and the differential diagnosis of pancreatic malignancies is difficult, making it easily misdiagnosed. Surgical resection is the preferred method of treatment for IMT. In this case report, we report a rare case of IMT in the neck of the pancreas and reviewed the relevant literature. In our case, the patient was a 57-year-old woman with an IMT in the neck of the pancreas. Abdominal pain was the only clinical symptom, and imaging features were not specific. She underwent surgery to remove the pancreatic mass, and the final diagnosis of IMT was based on histopathology and immunohistochemistry. After 6 months of regular follow-up, the patient had no complications or further incidents. The purpose is to emphasize the difficulty of the preoperative diagnosis of pancreatic IMT and the difficulty of distinguishing it from pancreatic malignancies. It is hoped that clinicians can gain a deeper understanding of pancreatic IMT through this case report.

Background Skip lymphatic metastasis (SK) is an exceptional and characteristic pattern of lymph node metastasis in gastric cancer (GC) with infrequent incidence. This is an extremely rare report of occult gastric cancer with solitary skip lymphatic metastasis as the initial and primary observation. Case presentation A 61-year-old woman, who complained of epigastric discomfort for several years, presented a solitary nodule upon pancreas neck examination by CT without performance on the primary lesion, even gastroscopy. During the preoperative 4-month follow-up, the nodule stayed stable without any therapy. The postoperative pathological examination confirmed the consistent diagnosis of gastric adenocarcinoma between the nodule and the stomach lesion, which was found by preoperative random biopsy of the mucosa. Conclusions This case highlights the concentration on vigilance to the SK of GC and a closer observation for intra-abdominal nodules, even radiological suspicion of a benign lesion.

A 62‑year‑old female presented with abdominal pain and was diagnosed as acute on chronic pancreatitis based on elevated serum amylase and imaging findings. The pancreatic duct was dilated with abrupt cutoff at neck of pancreas, but no mass was visualized. Positron emission tomography‑computed tomography (PET‑CT) revealed a fluorodeoxyglucose (FDG) avid lesion in the neck of the pancreas but ultrasound (USG)‑guided fine‑needle aspiration (FNA) from the lesion revealed only inflammatory cells. Endoscopic ultrasound, done 2 days after USG‑guided FNA, revealed pseudoaneurysm (PA) in the neck of pancreas that was confirmed on CT angiography. The PA was occluded by USG‑guided percutaneous cyanoacrylate injection. As pain persisted, repeat PET CT was done which revealed FDG avidity around the cyanoacrylate cast as well in multiple small hypodense lesions in the right lobe of the liver. USG‑guided FNA from both the liver lesion as well as the periphery of the glue cast revealed features of adenocarcinoma. We herein report a case of pancreatic adenocarcinoma that presented as acute pancreatitis and got masked because of formation of PA consequent to USG‑guided FNA.

A 12-year-old girl was admitted as an emergency with blunt pancreatic trauma. Computed tomography (CT) showed an intact pancreas. She failed conservative treatment. Endoscopic retrograde cholangiopancreatography (ERCP) demonstrated division of the pancreatic duct at the neck of pancreas. At laparotomy, however, there was complete necrosis of the pancreatic head. She recovered well following enteric drainage of the body of pancreas. CT and ERCP are considered the optimal imaging for pancreatic trauma but the findings may be misleading.
