Aims And Background: Intraoperative blood loss during liver resection remains a major concern due to its association with higher postoperative complications and shorter long-term survival. The aim of this study was to assess the feasibility and safety of a novel concept for liver resection using a radiofrequency energy-assisted technique.
Methods: From January 2001 to July 2002, 42 patients were operated on using radiofrequency energy-assisted liver resection. Radiofrequency energy was applied along the resection edge to create a 'zone of desiccation' prior to resection with a scalpel.
Results: Median resection time was 50 mins (range, 30-110). The median blood loss during resection was 30 mL (range, 15-992). Mean preoperative and postoperative hemoglobin values were 13.7 g/dL (SD +/- 1.6) and 11.8 g/dL (SD +/- 1.4), respectively. No blood transfusion was registered, nor was any mortality observed. There were 3 postoperative complications, one subphrenic abscess, one chest infection and one biliary leak from a hepatico-jejunostomy. Median postoperative stay was 8 days (range, 5-86).
Conclusions: Liver resection assisted by radiofrequency energy is feasible, easy and safe. This novel technique offers a new method for 'transfusion-free' resection without the need for sutures, ties, staples, tissue glue or admission to an intensive care unit.

Background: Hepatocellular Carcinoma (HCC) and cholangiocellular adenocarcinoma (CCA) are the most common primary liver tumors representing a major global health burden. In early disease stages, tumor resection may provide long-term survival in selected patients. However, morbidity and mortality rates are still relatively high after extended liver surgery with perioperative bacterial infections representing major complications.

Background: Neuroendocrine liver metastases (NELM) significantly reduce survival in patients with neuroendocrine tumor. The management of NELM is challenged by a low rate of resectability and a high rate of recurrence. Indocyanine green (ICG) fluorescence imaging offers potential advantages in real-time tumor visualization and margin assessment.

Background: Minimally invasive liver surgery (MILS) is superior to open surgery when considering decreased blood loss, fewer complications, shorter hospital stay, and similar or improved oncologic outcomes. However, operative limitations in laparoscopic hepatectomy have curved its applicability and momentum of complex minimally invasive liver surgery. Transitioning to robotic hepatectomy may bridge this complexity gap.

Background: Anatomical liver resection has been altered by a deeper understanding of the internal structure of the liver, highlighting the importance of the intersegmental plane, a region lacking Glissonean branches. These insights have enabled a novel surgical technique focused on the precise detachment of the intersegmental plane, supported by indocyanine green (ICG) fluorescent imaging and robotic platforms, enhancing the precision and safety of liver resection.
Methods: This study involved four patients who underwent robotic left hepatectomy using the Da Vinci Xi system.

Unlabelled: Perioperative neurocognitive disorders (PND) are common complications following surgery and anesthesia, especially in the elderly. These disorders are associated with disruptions in neuronal energy metabolism and mitochondrial function. This study explores the potential of intranasal insulin administration as a therapeutic strategy to prevent PND by targeting the calcium transport protein complex IP3R/GRP75/VDAC1 on mitochondria-associated endoplasmic reticulum membranes (MAMs).
