CP-673451, a Selective Platelet-Derived Growth Factor Receptor Tyrosine Kinase Inhibitor, Induces Apoptosis in -Associated Cholangiocarcinoma via Nrf2 Suppression and Enhanced ROS.

Platelet-derived growth factors (PDGFs) and PDGF receptors (PDGFRs) play essential roles in promoting cholangiocarcinoma (CCA) cell survival by mediating paracrine crosstalk between tumor and cancer-associated fibroblasts (CAFs), indicating the potential of PDGFR as a target for CCA treatment. Clinical trials evaluating PDGFR inhibitors for CCA treatment have shown limited efficacy. Furthermore, little is known about the role of PDGF/PDGFR expression and the mechanism underlying PDGFR inhibitors in CCA related to (OV).

Comparative outcomes of extended distal pancreatectomy and distal pancreatectomy.

Purpose: Patients with locally advanced pancreatic body/tail tumors, gastric cancer, or colon cancer often have contiguous organ involvement requiring extensive pancreatic resection. This study was performed to compare surgical complications and the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) between distal pancreatectomy (DP) with extended organ resection and standard DP.

Methods: In total, 128 patients who underwent DP from January 2012 to January 2021 were retrospectively reviewed.

Timing of laparoscopic cholecystectomy after endoscopic retrograde cholangiopancreatography in cholelithiasis patients: A systematic review and meta-analysis.

There are many variations and unclear definitions of the appropriate timing of laparoscopic cholecystectomy (LC) after endoscopic retrograde cholangiopancreatography (ERCP), and there is still a lack of consistency about the appropriate timing. Inappropriate timing can be associated with serious comorbidity and can affect the patients. This meta-analysis was conducted to assess the operative outcomes and morbidity to provide a benefit to the patients based on the best timing of LC after ERCP.

Early postoperative serum aspartate aminotransferase for prediction of post-hepatectomy liver failure.

Background: Post-hepatectomy liver failure (PHLF) is a serious complication of hepatectomy. The current criteria for PHLF diagnosis (ISGLS consensus) require laboratory data on or after postoperative day (POD) 5, which may delay treatment for patients at risk. The present study aimed to determine the associations between early postoperative (POD1) serum aminotransferase levels and PHLF.

Effect of local anaesthetic infiltration on postoperative pain after laparoscopic cholecystectomy: randomized clinical trial.

Background: Local anaesthetic infiltration is widely used to reduce pain after laparoscopic cholecystectomy (LC). This trial evaluated the effect of depth of local anaesthetic infiltration on postoperative pain reduction after LC.

Methods: Patients undergoing elective LC between March 2018 and February 2019 were randomized into no infiltration, subcutaneous infiltration, and rectus sheath infiltration using bupivacaine.

Association of the rate of bilirubin decrease with major morbidity in patients undergoing preoperative biliary drainage before pancreaticoduodenectomy.

Objective: The objective of this study was to examine the relationship between the rate of bilirubin decrease following preoperative biliary drainage before pancreaticoduodenectomy and postoperative morbidity.

Methods: Records of patients who underwent pancreaticoduodenectomy at the Department of Surgery in Ramathibodi Hospital between January 2008 and December 2019 were retrospectively reviewed. The patients were classified into either an adequate or inadequate drainage rate groups according to the bilirubin decrease rate.

Prospective randomized controlled trial of omental roll-up technique on pancreatojejunostomy anastomosis for reducing perioperative complication in patients undergoing pancreatoduodenectomy.

Background: Wrapping pancreatojejunal anastomosis with omentum to prevent postoperative pancreatic fistula (POPF) has only been reported in non-randomized, controlled trials. Therefore, this study aimed to conduct a randomized, controlled trial to compare outcomes between omental roll-up and non-omental roll-up in pancreatojejunal anastomosis.

Methods: This single-center, randomized, two-arm trail (Clinical Trials Register: NCT03083938) was conducted between February 2017 and February 2019.

Is It Reasonable to Use Indocyanine Green Fluorescence Imaging to Determine the Border of Pedicled TRAM Flap Zone IV?

Background: The contralateral lateral section (zone IV) of a pedicled transverse rectus abdominis musculocutaneous (TRAM) flap is generally removed intraoperatively. The border of zone IV is usually identified anatomically using the Hartrampf classification. In this study, we used the indocyanine green (ICG) fluorescence method to determine the border of zone IV and find the correlation with clinical flap outcome.

Predictors of surgical site infection after pancreaticoduodenectomy.

Background: Surgical site infection (SSI) is one of the most common complications after pancreaticoduodenectomy (PD). Thus, it is beneficial to preoperatively identify patients at high risk of developing SSI. The primary aim of the present study was to identify the factors associated with SSI after PD, and the secondary aim was to identify the adverse outcomes associated with the occurrence of SSI.

Fluorescence cholangiography enhances surgical residents' biliary delineation skill for laparoscopic cholecystectomies.

Background: Laparoscopic cholecystectomy (LC) is a minimally invasive procedure, often performed by surgical residents (SRs). Fluorescence cholangiography (FC) enables real-time identification of biliary anatomy.

Aim: To investigate the benefit of FC for enhancing SRs' identification skills.

Outcomes of delayed endoscopic retrograde cholangiopancreatography in patients with acute biliary pancreatitis with cholangitis.

Objective: The recommended treatment for acute biliary pancreatitis(ABP) with cholangitis is urgent endoscopic retrograde cholangiopancreatography(ERCP). However, tight schedules in the endoscopy room mean that urgent ERCP may not always be performed. This study aimed to compare the outcomes of early (≤72 h) and delayed(>72 h) ERCP in patients with ABP with cholangitis.

Preoperative serum albumin is associated with intra-abdominal infection following major hepatectomy.

Background: Major hepatectomy is a complex surgical procedure with high morbidity. Intra-abdominal infection (IAI) is common following hepatectomy and affects treatment outcomes. This study was performed to investigate perioperative factors and determine whether the preoperative serum albumin level is associated with IAI following major hepatectomy.
