N2 - PURPOSE: Associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) has increased the rate of liver resections in patients with marginal future liver remnant. We here describe a modified ALPPS procedure with splitting-off the central liver segments for staged mesohepatectomy in patients with advanced gall bladder cancer.METHODS: A double in situ split for ALPPS (DALPPS) is performed with splitting-off the central liver segments (segments 1, 4, 5, and 8). This induces a rapid hypertrophy of the left lateral (segments 2/3) and right posterior sectors (segments 6/7). An intrahepatic right posterior approach during splitting-off the right posterior sector is introduced as a part of this new procedure. This approach facilitates the dissection and ligation of the right anterior branch of the portal vein (segments 5 and 8) while the liver hilum remains untouched during the first step of surgery.RESULTS: Two patients with advanced gall bladder cancer were treated with the DALPPS procedure till date. After a short interval (7-9 days), a rapid hypertrophy of the left lateral and right posterior sector was observed (hypertrophy up to 72.6 and 54.6 %, respectively). A staged mesohepatectomy including caudate lobectomy and resection of the extrahepatic bile duct was then performed safely. There was no surgical-technical morbidity. No signs of posthepatectomy liver failure according to the 50-50 criteria were seen. However, one patient died from severe ARDS attributed to the preoperative chemotherapy. Nevertheless, this complication is deemed to be surgery related.CONCLUSIONS: The DALPPS procedure is a new surgical technique for staged mesohepatectomy for patients with small future liver remnant in size or in function. However, appropriate patient selection is mandatory to avoid morbidity and mortality.
