Introduction: We present our 6-year experience with liver surgery and ablative techniques. Method: An observational retrospective analysis from a prospectively maintained database was performed in our department. All the patients with liver resection, liver resection combined with intraoperative ablative techniques and percutaneous ablative techniques were included from January 1st 2014 to December 31st 2020. Results: There were 249 patients analyzed: 273 patients with liver resection, 12 patients with liver resection combined with intraoperative MWA, 9 patients with open surgery MWA, 12 patients with percutaneous MWA, 1 patient with TACE and MWA, 1 patient with TACE and PEI, 10 patients with TACE, and 2 patients with PEI. Conclusion: Liver disease should be managed in specialized centers which can offer a wide range of therapeutic options. With the improvement of the surgical technique and perioperative care, including optimized postoperative complication management, and carried out by well-trained surgeons, liver surgery can be performed with low mortality and acceptable morbidity.

Reinforcement of posterior cruroplasty has been proposed to minimize the failure of hiatal hernia repair (HHR). The applications of autologous platelet-rich plasma (PRP) and absorbable mesh are barely reported in this area.To analyze local macroscopic and microscopic changes induced by mesh vs. PRP as reinforcement of HHR, using a reliable laparoscopic experimental porcine model.This prospective, comparative pilot study was conducted on 14 female pigs, aged four to six months. An iatrogenic hiatal defect was laparoscopically simulated and repaired, reinforced with Bio-A® mesh (group A) or PRP (group B). Specimen retrieval was performed after seven months for histopathological (HP) examination.No local or general complications were registered, with complete resorption of reinforcements, that determined inflammatory infiltrates with local collagen production and tissue neo-vascularization. Group A had an increased mean chronic inflammation score (No residual materials or evidence of anatomical distortion were found. Animal model was safe and reliable. This is the first report of complete absorption of Bio-A

An association of pancreatic cancer and median arcuate ligament syndrome (MALS) is a rare and challenging situation in terms of treatment. A 60-year-old man diagnosed with pancreatic cancer underwent laparotomy. A pancreaticoduodenectomy was planned, but during the resection part of the operation, a celiac artery stenosis was noticed. The patient was diagnosed with MALS causing almost total celiac artery occlusion, with no radiological solution. The patient was re-operated the next day, and an iliac artery allograft was used for aorta-proper hepatic artery reconstruction, concomitant with the total pancreaticoduodenectomy. Preoperative meticulous evaluation of vascular structures of the celiac trunk and its branches is important, especially in pancreatic surgery. A vascular allograft may be a lifesaving alternative when vascular reconstruction is necessary.
