We report the case of a 39-year-old woman who underwent morphological examination (CT-scan and MRI) for poorly systematized abdominal pain, which demonstrated the presence of a unilocular macrocystic lesion at the tail of the pancreas. The diagnosis established reported a mucinous cystadenoma, and a robotic distal spleen-preserving pancreatectomy was decided upon. The dissection is initiated at the inferior border of the pancreas. Dissection has been performed at the level of the splenic hilum with freeing of the pancreatic tail. The splenic branches of the splenic vein are identified at the posterior aspect of the pancreas. These branches are freed progressively. As a result, the distal part of the pancreas is freed from the splenic hilum, and dissection will be performed from left to right. This dissection was decided upon as the lesion is located very distally. The splenic vein and the splenic artery are freed at the level of the hilum. Dissection is continued progressively to the right. Dissection of the cyst in relation to the splenic vein is uneasy as there are several inflammatory adhesions. Dissection is then performed at the isthmic part of the pancreas. The splenic artery is dissected at the superior border of the pancreas. Dissection is then carried out at the posterior aspect of the pancreas. Considering the presence of adhesions, the operative strategy is changed. It is decided to perform a distal pancreatectomy with preservation of the spleen without vessels preservation. However, the splenic vessels are divided. Consequently, the splenic artery is ligated by a clip and divided. The distal part of the splenic artery is also ligated. Proximally, the splenic vein is dissected and divided. The distal part has also been clipped. The distal division of arterial and venous vessels is performed. The pancreas was divided at the level of its body. The specimen is placed into a bag and extracted by means of a small Pfannenstiel incision. At the end of the procedure, the spleen appears to be well-vascularized by short vessels. The CT-scan performed on postoperative day 5 demonstrates that the spleen is well-vascularized and rules out the presence of any collection in the place left by pancreatectomy. The postoperative outcome is uneventful. There is no pancreatic fistula. The patient is discharged on postoperative day 7. Pathological findings confirm the presence of a mucinous cystadenoma without any malignancy.
