Comparative analysis of analgesic efficacy and functional recovery in open pancreaticoduodenectomy: a randomized controlled trial of local anesthetic wound infiltration, transversus abdominis plane block, and intramuscular electrical stimulation.

Background: Pancreaticoduodenectomy (PD) is associated with severe postoperative pain. Optimized pain management can potentially elevate patients' postoperative quality of life. This study focused on comparing the analgesic efficacy and subsequent functional recovery of three techniques, continuous local wound infiltration (LWI), four-quadrant transversus abdominis plane (4QTAP) block, and needle electrical twitch obtaining intramuscular stimulation (NETOIMS), in patients subjected to open PD.

Albumin Leakage Level during Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy Is Associated with Major Complications.

The clinical consequences of perioperative albumin extravasation accompanying major abdominal surgery remain underexplored. We retrospectively reviewed the data of patients who underwent cytoreductive surgery (CRS) and hyperthermic intraoperative peritoneal chemotherapy (HIPEC). Parameters of albumin kinetics, including serum albumin concentration decrease (∆Alb) and extravasated albumin level (Alb), were assessed from surgery until postoperative day (POD) 3.

Generation of An Induced Pluripotent Stem Cell Line from Human Liver Fibroblasts from A Patient with Combined Hepatocellular-Cholangiocarcinoma.

Objective: Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare type of primary liver cancer with characteristics of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). The pathogenesis of cHCCCC is poorly understood due to a shortage of suitable in vitro models. Due to scarce availability of human liver tissue, induced pluripotent stem cells (iPSCs) are a useful alternative source to produce renewable liver cells.

Long-Term Expansion of Functional Human Pluripotent Stem Cell-Derived Hepatic Organoids.

A human cell-based liver model capable of long-term expansion and mature hepatic function is a fundamental requirement for pre-clinical drug development. We previously established self-renewing and functionally mature human pluripotent stem cell-derived liver organoids as an alternate to primary human hepatocytes. In this study, we tested long-term prolonged culture of organoids to increase their maturity.
