Outcome of Minimally Invasive and Open Pancreatoduodenectomy in Patients with Intestinal- and Pancreatobiliary Subtype Ampullary Cancer: An International Multicenter Cohort Study.

Objective: To compare minimally invasive and open pancreatoduodenectomy in different subtypes of ampullary adenocarcinoma.

Summary Background Data: Ampullary adenocarcinoma (AAC) is widely seen as the best indication for minimally invasive pancreatoduodenectomy (MIPD) due to the lack of vascular involvement and dilated bile and pancreatic duct. However, it is unknown whether outcomes of MIPD for AAC differ between the pancreatobiliary (AAC-PB) and intestinal (AAC-IT) subtypes as large studies are lacking.

The Five Periampullary Cancers, not Just Different Siblings but Different Families: An International Multicenter Cohort Study.

Background: Cancer arising in the periampullary region can be anatomically classified in pancreatic ductal adenocarcinoma (PDAC), distal cholangiocarcinoma (dCCA), duodenal adenocarcinoma (DAC), and ampullary carcinoma. Based on histopathology, ampullary carcinoma is currently subdivided in intestinal (AmpIT), pancreatobiliary (AmpPB), and mixed subtypes. Despite close anatomical resemblance, it is unclear how ampullary subtypes relate to the remaining periampullary cancers in tumor characteristics and behavior.

The road to tailored adjuvant chemotherapy for all four non-pancreatic periampullary cancers: An international multimethod cohort study.

Background: Despite differences in tumour behaviour and characteristics between duodenal adenocarcinoma (DAC), the intestinal (AmpIT) and pancreatobiliary (AmpPB) subtype of ampullary adenocarcinoma and distal cholangiocarcinoma (dCCA), the effect of adjuvant chemotherapy (ACT) on these cancers, as well as the optimal ACT regimen, has not been comprehensively assessed. This study aims to assess the influence of tailored ACT on DAC, dCCA, AmpIT, and AmpPB.

Patients And Methods: Patients after pancreatoduodenectomy for non-pancreatic periampullary adenocarcinoma were identified and collected from 36 tertiary centres between 2010 - 2021.

Differences in Lymph Node Metastases Patterns Among Non-pancreatic Periampullary Cancers and Histologic Subtypes: An International Multicenter Retrospective Cohort Study and Systematic Review.

Background: Standard lymphadenectomy for pancreatoduodenectomy is defined for pancreatic ductal adenocarcinoma and adopted for patients with non-pancreatic periampullary cancer (NPPC), ampullary adenocarcinoma (AAC), distal cholangiocarcinoma (dCCA), or duodenal adenocarcinoma (DAC). This study aimed to compare the patterns of lymph node metastases among the different NPPCs in a large series and in a systematic review to guide the discussion on surgical lymphadenectomy and pathology assessment.

Methods: This retrospective cohort study included patients after pancreatoduodenectomy for NPPC with at least one lymph node metastasis (2010-2021) from 24 centers in nine countries.

Different Periampullary Types and Subtypes Leading to Different Perioperative Outcomes of Pancreatoduodenectomy: Reality and Not a Myth; An International Multicenter Cohort Study.

This international multicenter cohort study included 30 centers. Patients with duodenal adenocarcinoma (DAC), intestinal-type (AmpIT) and pancreatobiliary-type (AmpPB) ampullary adenocarcinoma, distal cholangiocarcinoma (dCCA), and pancreatic ductal adenocarcinoma (PDAC) were included. The primary outcome was 30-day or in-hospital mortality, and secondary outcomes were major morbidity (Clavien-Dindo 3b≥), clinically relevant post-operative pancreatic fistula (CR-POPF), and length of hospital stay (LOS).

Primary Graft Dysfunction: Factor V's Value for Its Early Diagnosis.

Background: Primary graft dysfunction is a common postoperative complication, lacking consensus regarding diagnostic criteria. Olthoff criteria are the most used, based on blood parameters in the first 7 postoperative days. This lack of consensus and late diagnosis evidence the need of early parameters.

Steatotic hepatocellular adenoma: an unusual cause of a hypermetabolic liver lesion.

A 22-year-old woman with a history of surgically treated pelvic teratoma and solid liver lesion in the extension study. Radiological follow-up was decided. This liver lesion experienced a progressive increase in size, reaching 6 cm.

Intraoperative gram staining of bile for the prevention of infectious complications in pancreaticoduodenectomy.

Introduction: Infectious complications play a prominent role in pancreaticoduodenectomy. Their incidence increases in cases with preoperative biliary drainage (PBD), due to the higher risk of bacterobilia. The aim of this study is to evaluate an antibiotherapy protocol based on intraoperative gram staining of bile and its impact on postoperative infectious complications.

Liver resection in elderly patients with extensive CRLM: Are we offering an adequate treatment? A propensity score matched analysis.

Background: Data on the management of elderly patients with extensive colorectal liver metastases (CRLM) are scarce and conflicting. This study assesses differences in management and long-term oncological outcomes between older and younger patients with CRLM and a high Tumour Burden Score (TBS).

Methods: International multicentre retrospective study on patients with CRLM and a category 3 TBS, submitted to liver resection.

Outcome of Liver Transplants Using Donors After Cardiac Death With Normothermic Regional Perfusion.

Background And Aims: The incorporation of normothermic regional perfusion (NRP) to donors after cardiac death (DCD) allows the recovery of liver grafts without the deleterious effects on graft survival the super-rapid technique may cause. The aim of the present report is to determine if the use of NRP in Maastricht type III DCD donors achieves short- and medium-term results comparable to donors after brain death (DBD).

Patients And Methods: This is an observational cohort study including 117 liver transplants executed between November 2016 and April 2021, divided into NRP (n = 39) and DBD (n = 78).

Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID).

Background: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients.

Methods: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020.

Intraoperative gram staining of bile for the prevention of infectious complications in pancreaticoduodenectomy.

Introduction: Infectious complications play a prominent role in pancreaticoduodenectomy. Their incidence increases in cases with preoperative biliary drainage (PBD), due to the higher risk of bacterobilia. The aim of this study is to evaluate an antibiotherapy protocol based on intraoperative gram staining of bile and its impact on postoperative infectious complications.

Results of a survey on peri-operative nutritional support in pancreatic and biliary surgery in Spain.

Introduction: a survey on peri-operative nutritional support in pancreatic and biliary surgery among Spanish hospitals in 2007 showed that few surgical groups followed the 2006 ESPEN guidelines. Ten years later we sent a questionnaire to check the current situation. Methods: a questionnaire with 21 items sent to 38 centers, related to fasting time before and after surgery, nutritional screening use and type, time and type of peri-operative nutritional support, and number of procedures.

Influence of Preoperative Muscle Mass Assessed by Computed Tomography on Prognosis After Liver Transplantation.

Background: Sarcopenia (SP) and preoperative muscle mass are independent predictive factors for short- and long-term outcome of liver transplantation.

Objective: To assess the influence of muscle mass index (MMI) and preoperative SP on the prognosis of patients who underwent liver transplantation in our hospital.

Methods: Ninety-seven patients who underwent liver transplantation in the Regional University Hospital of Málaga from September 2013 to March 2016 were analyzed.

Results of liver transplantation with donors older than 80 years: a case control study.

Aim: The inclusion of elderly donors can increase the pool of organs available for transplant.

Background: To compare clinical outcomes and survival rates in patients who received livers from donors aged ≥ 80 years vs. younger donors.

A post-endoscopic retrograde cholangiopancreatography subcapsular hepatic hematoma.

Nowadays endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive technique with a complication rate around 2.5% in expert hands, being the most frequent: acute pancreatitis, cholangitis, hemorrhage and perforation. An exceptional complication is subcapsular hepatic hematoma, first published in the literature in 2000, with few cases reported.
