High-Risk Biliary Anastomosis During Robotic Pancreaticoduodenectomy: Initial Experience with Biodegradable Biliary Stent.

: Biliary fistulas (BFs) occur in approximately 3-8% of patients undergoing pancreaticoduodenectomy (PD), and the bile duct diameter ≤ 5 mm is the most important risk factor. The aim of this study was to evaluate the efficacy of biodegradable biliary stents (BSs) in reducing complications in patients undergoing robotic pancreaticoduodenectomy (RPD) with a bile duct diameter of ≤5 mm. : A retrospective single-centre observational study was conducted.

Effect of warm and cold ischemia on pancreaticoduodenectomy specimen following robotic pancreaticoduodenectomy.

Background: The adoption of robotic pancreaticoduodenectomy (PD) has increased in recent years for the treatment of pancreatic head tumors and periampullary lesions. Some potential benefits seem to be demonstrated; however, obtaining specimens through this method can potentially compromise the diagnosis depending on the timing of the specimen retrieval, and the impact of longer perioperative time on ischemia and autolysis of the surgical specimen has not been analyzed. The aim of this study is to evaluate the histological changes associated with timing of specimen retrieval during robotic PD.

Cost-effectiveness of robotic vs laparoscopic distal pancreatectomy. Results from the national prospective trial ROBOCOSTES.

Introduction: Although several studies report that the robotic approach is more costly than laparoscopy, the cost-effectiveness of robotic distal pancreatectomy (RDP) over laparoscopic distal pancreatectomy (LDP) is still an issue. This study evaluates the cost-effectiveness of the RDP and LDP approaches across several Spanish centres.

Methods: This study is an observational, multicenter, national prospective study (ROBOCOSTES).

Conversion to open surgery in obese patients undergoing minimally invasive distal pancreatectomy: results from a multicenter analysis.

Background: Although minimally invasive distal pancreatectomy (MIDP) is considered a standard approach it still presents a non-negligible rate of conversion to open that is mainly related to some difficulty factors, as obesity. The aim of this study is to analyze the preoperative factors associated with conversion in obese patients with MIDP.

Methods: In this multicenter study, all obese patients who underwent MIDP at 18 international expert centers were included.

Pancreaticoduodenectomy in a patient with severe portal hypertension: the role of preoperative TIPS.

The complication rate for Pancreaticoduodenectomy (PD) is 40-50% in most published series and mortality can raise up to 4-5% even in high-volume centers. Severe portal hypertension secondary to liver disease is associated to high perioperative mortality and therefore is considered a contraindication for PD. No standardized management exists for surgically resectable patients with periampullary cancer and severe portal hypertension.

Robotic versus laparoscopic distal pancreatectomy for pancreatic adenocarcinoma in obese patients.

Background: Robotic distal pancreatectomy (RDP) is associated with a lower conversion rate and less blood loss than laparoscopic distal pancreatectomy (LDP). LDP has similar oncological outcomes as open surgery in PDAC. The aim of this study was to compare perioperative and oncological outcomes in obese patients with RDP versus LDP for PDAC.

Predictive Value of Antithrombin III and d -Dimer in the Development of Moderate-To-Severe Acute Pancreatitis : A Prospective, Observational Study (AT-PROPANC).

Objectives: To analyze if antithrombin III (AT-III) and d -dimer levels at admission and at 24 hours can predict acute pancreatitis (AP) progression to moderately severe AP (MSAP) to severe AP (SAP) and to determine their predictive value on the development of necrosis, infected necrosis, organ failure, and mortality.

Methods: Prospective observational study conducted in patients with mild AP in 2 tertiary hospitals (2015-2017).

Results: Three hundred forty-six patients with mild AP were included.

Incisional Hernia Following Open Pancreaticoduodenectomy: Incidence and Risk Factors at a Tertiary Care Centre.

(1) Background: Incisional hernia (IH) is one of the most common complications following open abdominal surgery. There is scarce evidence on its real incidence following pancreatic surgery. The purpose of this study is to evaluate the incidence and the risk factors associated with IH development in patients undergoing pancreaticoduodenectomy (PD).

Intraoperative indocyanine green clearance in liver surgery: a useful tool to promote parenchymal preservation?

A 66-year-old woman was diagnosed with sigmoid carcinoma with bilobar unresectable liver metastases. Primary tumor resection was performed. Neoadjuvant chemotherapy was administered to downstage liver disease.

Abdominal normothermic regional perfusion in controlled donation after circulatory determination of death liver transplantation: Outcomes and risk factors for graft loss.

Postmortem normothermic regional perfusion (NRP) is a rising preservation strategy in controlled donation after circulatory determination of death (cDCD). Herein, we present results for cDCD liver transplants performed in Spain 2012-2019, with outcomes evaluated through December 31, 2020. Results were analyzed retrospectively and according to recovery technique (abdominal NRP [A-NRP] or standard rapid recovery [SRR]).

Quantitative Indocyanine Green Fluorescence Imaging Assessment for Nonmucinous Peritoneal Metastases: Preliminary Results of the ICCP Study.

Background: In selected patients with peritoneal metastases of colorectal origin, complete cytoreduction has been the main single prognostic factor influencing long-term outcomes. In these patients, indocyanine green fluorescence imaging seems to be useful in detecting small subclinical peritoneal implants. However, quantitative fluorescence analysis has not yet been established as standard.

Transanal total mesorectal excision for stage II or III rectal cancer: pattern of local recurrence in a tertiary referral center.

Background: For mid and low rectal cancer, transanal total mesorectal excision (TaTME) has been established as an alternative approach to laparoscopic surgery. However, there are concerns about an unexpected pattern of local recurrence. This study aimed to analyze the pattern of local recurrence for patients treated with TaTME in a tertiary referral center.

Role of Kupffer cells in the progression of CRC liver metastases after the first stage of ALPPS.

Associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been suggested as a potential therapy for extensive bilobar liver tumors, although in some circumstances this technique may induce tumor progression, a fact still not well studied. Our aim was to study tumor hepatic progression induced by the first step of ALPPS in a WAG/Rij rat syngenic model of metastatic colorectal carcinoma by subcapsular CC531 cell line inoculation. ALPPS induced: tumor progression on deportalized lobe and metastases; expression of hepatic vasculogenic factors (HIF1-α and VEGF); and a dramatic increase of Kupffer cells (KCs) and tumor-associated macrophages (TAMs).
