ABSTRACT
BACKGROUND: In primarily unresectable liver tumors, ALPPS (Associating Liver Partition and Portal Vein Ligation for Staged hepatectomy) may offer curative two-stage hepatectomy trough a fast and extensive hypertrophy. However, concerns have been raised about the invasiveness of the procedure. Full robotic ALPPS has the potential to reduce the postoperative morbidity trough a less invasive access. The aim of this study was to compare the perioperative outcomes of open and full robotic ALPPS. METHODS: The bicentric study included open ALPPS cases from the University Hospital Zurich, Switzerland and robotic ALPPS cases from the University of Modena and Reggio Emilia, Italy from 01/2015 to 07/2022. Main outcomes were intraoperative parameters and overall complications. RESULTS: Open and full robotic ALPPS were performed in 36 and 7 cases. Robotic ALPPS was associated with less blood loss after both stages (418 ± 237 ml vs. 319 ± 197 ml; P = 0.04 and 631 ± 354 ml vs. 258 ± 53 ml; P = 0.01) as well as a higher rate of interstage discharge (86% vs. 37%; P = 0.02). OT was longer with robotic ALPPS after both stages (371 ± 70 min vs. 449 ± 81 min; P = 0.01 and 282 ± 87 min vs. 373 ± 90 min; P = 0.02). After ALPPS stage 2, there was no difference for overall complications (86% vs. 86%; P = 1.00) and major complications (43% vs. 39%; P = 0.86). The total length of hospital stay was similar (23 ± 17 days vs. 26 ± 13; P = 0.56). CONCLUSION: Robotic ALPPS was safely implemented and showed potential for improved perioperative outcomes compared to open ALPPS in an experienced robotic center. The robotic approach might bring the perioperative risk profile of ALPPS closer to interventional techniques of portal vein embolization/liver venous deprivation.

Neuroendocrine tumors of the pancreas (NETP) represent only 1%-2% of all pancreatic neoplasms. They can be classified as functioning or non-functioning, respectively, according to the presence or absence of paraneoplastic syndrome. Case 1 concerned a 70-year-old woman with a cystic lesion of the pancreatic head and body. All tumor markers were negative. The patient underwent a distal pancreatectomy. The histology revealed a well-differentiated endocrine tumor with uncertain malignant potential. Case 2 was a 61-year-old man with chronic polyserositis. The serum tumor markers were negative, while he was strongly positive for intracystic tumor markers carcinoembryonic antigen, carbohydrate antigen (CA) 19-9, and CA 125. The patient underwent a cephalo-pancreatic duodenectomy. The preoperative differential diagnosis of cystic NETP is still a challenge due to the high rate of the nonfunctional variant. Although cystic NETPs are well differentiated, they are still tumors with a malignant potential, and therefore an early diagnosis and radical surgical resection could be associated with a better long-term survival.
