Liver robotic

BACKGROUND: Economic impact of robotic liver surgery (RLS) is still a debated issue due to the heterogeneity of liver resections considered and the lack of a rigorous methodology. Therefore, the aim of this study is to perform a time-driven activity-based costing (TD-ABC) comparing the costs of RLS, laparoscopic liver surgery (LLS) and open liver surgery (OLS) in the context of complex liver resections and to compare short term perioperative outcomes. METHODS: The institutional databases of two Italian high volume hepatobiliary centres were retrospectively reviewed from February 2021 to April 2022...

INTRODUCTION: Although stereotactic ablative radiotherapy (SABR) has advance to standard-of-care for many different indications like lung and liver malignancies, it still remains in its infancy for treating head and neck cancer. Nevertheless there is a growing body of experience and evidence, which is summarized in this review Methods A thorough search of the literature was performed and critically reviewed both for SABR as a primary treatment as well as for treating locoregionally recurrent disease in a pre-irradiated field...

Current meta-analysis was performed to compare robotic hepatectomy (RH) with conventional open hepatectomy (OH) in terms of peri-operative and postoperative outcomes. PubMed, EMBASE, and the Cochrane Library were all searched up for comparative studies between RH and OH. RevMan5.3 software and Stata 13.0 software were used for statistical analysis. Nineteen studies with 1747 patients who received RH and 23,633 patients who received OH were included. Pooled results indicated that patients who received RH were generally younger than those received OH (P < 0...

Postoperative hepatobiliary enzyme abnormalities often present as postoperative liver dysfunction in patients with gastric cancer (GC). This study aimed to identify the risk factors for postoperative liver dysfunction and their clinical impact after GC surgery. We retrospectively analyzed the data of 124 patients with GC who underwent laparoscopic or robotic surgery at Kyoto Prefectural University of Medicine between 2017 and 2019. Twenty (16.1%) patients with GC developed postoperative liver dysfunction (Common Terminology Criteria for Adverse Events (CTCAE) version 5...

The distal bile duct was isolated and transected with a frozen section examination confirming the absence of malignancy. Attention was then shifted to constructing a 60 cm Roux limb by first identifying and transecting the proximal jejunum 40 cm from the ligamentum of Treitz. A side-to-side stapled jejunojejunostomy anastomosis was completed. The Roux limb was transposed toward the porta hepatis through an antecolic approach.

The use of robotic surgery in transplantation is increasing, however, robotic liver transplant (RLT) remains a challenging undertaking. This is a report of the first RLT in North America and the first robotic LT using a whole graft from a deceased donor in the world. This paper describes the preparation leading to the RLT and the surgical technique of the operation. The operation was performed in a 62-year old male with hepatitis C cirrhosis and hepatocellular carcinoma (HCC) with a native MELD score of 10...

BACKGROUND: IWATE, Institut Mutualiste Montsouris (IMM), and Southampton are established difficulty scoring systems (DSS) for laparoscopic hepatectomy, yet none specifically address robotic hepatectomy. Our study evaluates these 3 DSS for predicting perioperative outcomes in robotic hepatectomy. METHODS: With IRB approval, we prospectively followed 359 consecutive patients undergoing robotic hepatectomies, assessing categorical metrics like conversions to open, intra/postoperative issues, Clavien-Dindo Score (≥III), 30 and 90-day mortality, and 30-day readmissions using Receiver Operating Characteristic (ROC) curves and Area Under the Curve (AUC) to determine efficacy in predicting their occurrence for each DSS...

BACKGROUND/PURPOSE: There is uncertainty about the role of prophylactic intra-abdominal drains after distal pancreatectomy. In the present study, we aimed to describe the long-term outcomes of postoperative pancreatic collections in patients who underwent a minimally invasive distal pancreatectomy (MIDP) without surgical drain placement. METHODS: From 2018 to 2022, consecutive patients who underwent a MIDP were recorded. Patients were followed at 90 days, 6 months, and in the long term...

BACKGROUND: Minimally invasive anatomical resection (AR) for posterosuperior lesions is technically challenging.1,2 The Glissonean approach or puncture technique is generally selected.3,4 The tumor-feeding portal pedicle compression AR (C-AR) is an established procedure in open surgery.5 This technique has benefited from the association with indocyanine green (ICG) fluorescence, used to enhance the anatomical area to be resected.6 Recently, C-AR via the minimal access approach has been reported...

BACKGROUND: As the first comprehensive investigation into hospital readmissions following robotic hepatectomy for neoplastic disease, this study aims to fill a critical knowledge gap by evaluating risk factors associated with readmission and their impact on survival and the financial burden. METHODS: The study analyzed a database of robotic hepatectomy patients, comparing readmitted and non-readmitted individuals post-operatively using 1:1 propensity score matching...

BACKGROUND: The applicability of robot-assisted resection for huge hepatocellular carcinoma (HCC) of ≥10 cm remains contentious with limited available data. METHODS: This retrospective analysis involved 337 patients who underwent robotic liver resection for HCC by a single surgeon. Propensity score matching (PSM) was employed to compare perioperative indicators between patients with regular and huge HCC. RESULTS: The regular HCC group exhibited a shorter median operative duration than the huge HCC group...

Objective: To explore the effectiveness of minimally invasive surgical treatment for pancreatic acinar cell carcinoma (PACC). Methods: Six patients with PACC diagnosed in Peking University Third Hospital from January 2010 to September 2022 were retrospectively selected. Preoperative evaluation was performed on whether the lesions were eligible for surgery, including whether radical resection of liver metastases could be performed. Laparoscopic or Da Vinci robot-assisted resection was performed on six patients, and spleen retention was determined according to the original lesions and the relationship with peripheral blood vessels and tissues, while simultaneous resection was performed on cases of peripheral organ tissue invasion...

INTRODUCTION: Ultrasound has been nicknamed "the surgeon's stethoscope". The advantages of laparoscopic ultrasound beyond a substitute for the sense of touch are considerable, especially for robotic surgery. Being able to see through parenchyma and into vascular structures enables to avoid unnecessary dissection by providing a thorough assessment at every stage without the need for contrast media or ionising radiation. The limitations of restricted angulation and access within the abdominal cavity during laparoscopy can be overcome by robotic handling of miniaturised ultrasound probes and the use of various and specific frequencies will meet tissue- and organ-specific characteristics...

3D bioprinting possesses the potential to revolutionize contemporary methodologies for fabricating tissue models employed in pharmaceutical research and experimental investigations. This is enhanced by combining bioprinting with advanced Organs-on-a-Chip (OOCs), which includes a complex arrangement of multiple cell types representing organ-specific cells, connective tissue and vasculature. However, both OOCs and bioprinting so far demand a high degree of manual intervention, thereby impeding efficiency and inhibiting scalability to meet technological requirements...

Liver surgery is the cornerstone of the curative treatment of malignant liver tumors. However, the liver anatomy is very complex, and liver surgery is still associated with relevant morbidity despite many technical advances. The Brisbane nomenclature is used worldwide to classify liver resection. However, this nomenclature has several limitations as multiple terms are used for the same type of resection. Non-anatomical resections, multiple resections, and combined bilio-vascular resections were not mentioned...

BACKGROUND: A prolonged length of stay (LOS) after surgery may result in higher hospital costs and hospital-acquired complications. This study aims to identify the risk factors associated with a prolonged hospital stay after robot-assisted thoracoscopic lung surgery for pediatric patients in the context of enhanced recovery after surgery. METHODS: The data for this retrospective study were collected from pediatric patients undergoing robot-assisted thoracoscopic lung surgery...

BACKGROUND: We Published a step-up approach for robotic training in hepato-pancreato-biliary (HPB) surgery has been previously. The approach was mostly based on personal experience and communications between experts and needed appraisal and validation by the HPB surgical community. At the Great Britain and Ireland HPB Association (GBIHPBA) robotic HPB meeting held in Coventry, UK in October 2022, the authors sought consensus from the live audience, with an open forum for answering key questions...

BACKGROUND: Hepatic arterial infusion pump (HAIP) chemotherapy is an effective treatment for patients with unresectable intrahepatic cholangiocarcinoma (iCCA). HAIP chemotherapy requires a catheter inserted in the gastroduodenal artery and a subcutaneous pump. The catheter can be placed using an open or robotic approach. OBJECTIVE: This study aimed to compare perioperative outcomes of robotic versus open HAIP placement in patients with unresectable iCCA. METHODS: We analyzed patients with unresectable iCCA included in the PUMP-II trial from January 2020 to September 2022 undergoing robotic or open HAIP placement at Amsterdam UMC, Erasmus MC, and UMC Utrecht...

BACKGROUND: Videos on Robotic pancreaticoduodenectomy (RPD) may be watched by surgeons learning RPD. This study sought to appraise the educational quality of RPD videos on YouTube. METHODS: One-hundred videos showing RPD or 'Robotic Whipple' were assessed using validated scales (LAP-VEGaS & Consensus Statement Score (CSS)). The association between the scores and the video characteristics (e.g. order of appearance, provider type etc) was assessed. The minimum number of videos required to cumulatively cover the entire LAP-VEGaS and CSS was also noted...
