Introduction: The use of minimally invasive surgery for distal pancreatic mass with benign or borderline malignancy has caused paradigm shift among surgeons. Although the spleen is often routinely resected, splenic preservation in younger patients has become preferable for various reasons, even though dissection around the splenic artery and vein can be very challenging. In this video, we demonstrate a laparoscopic distal pancreatectomy with preservation of both the spleen and the splenic vessels.
Methods: A 31 year old obese woman with BMI of 43 kg/m2 was found to have an incidental 4-cm cystic mass at the posterior margin of the body-tail of the pancreas on a transabdominal ultrasonography during preoperative work-up for bariatric surgery. This finding was confirmed on a CT scan. A transgastric endoscopic ultrasonography with fine needle aspiration of the lesion revealed proteinaceus cystic contents without malignant cells (CEA-Carcinoembryonic Antigen: 1072 ng/mL). Laparoscopic distal pancreatectomy with preservation of both the spleen and the splenic vessels was performed, followed by a vertical sleeve gastrectomy [for the purpose of this presentation, only the laparoscopic distal pancreatectomy part is demonstrated]. The total operative time for the distal pancreatectomy was 4 hours with 100 ml blood loss. The supraumbilical port site was enlarged to approximately 4 cm and used as an extraction port for the specimen. A closed-suction drain was placed near the pancreatic stump. No intraoperative complications occured. An oral diet was resumed on postoperative day 1 and the patient was discharged on postoperative day 3.
Results: Final pathology was consistent with a mucinous cystic neoplasm with low grade dysplasia. Four weeks postoperatively, the patient was readmitted for a small left upper quadrant abdominal collection consistent with pancreatic leak. This collection resolved with a percutaneously-placed drain by interventional radiology.
Conclusions: Laparoscopic splenic and vessels-preserving distal pancreatectomy for a mass with benign or borderline malignancy is safe and technically feasible. High level of experience in advanced laparoscopy is required for a success of this technically complex resection.
