A Multiple-Instance Learning Approach for the Assessment of Gallbladder Vascularity from Laparoscopic Images [PDF]

arXiv, 2021
An important task at the onset of a laparoscopic cholecystectomy (LC) operation is the inspection of gallbladder (GB) to evaluate the thickness of its wall, presence of inflammation and extent of fat. Difficulty in visualization of the GB wall vessels may be due to the previous factors, potentially as a result of chronic inflammation or other diseases.

High resolution chromosome 3p, 8p, 9q and 22q allelotyping analysis in the pathogenesis of gallbladder carcinoma [PDF]

, 2002
Our recent genome-wide allelotyping analysis of gallbladder carcinoma identified 3p, 8p, 9q and 22q as chromosomal regions with frequent loss of heterozygosity.

Intracholecystic Papillary-tubular Neoplasm of the Gallbladder Presenting with Jaundice

Internal Medicine, 2014
We herein report a case of intracholecystic papillary-tubular neoplasm (ICPN) of the gallbladder in which jaundice developed. A 58-year-old woman with jaundice was referred to our hospital. Computed tomography revealed a papillary tumor in the body of the gallbladder protruding into the bile duct.

Possibility of incorrect evaluation of intraoperative blood loss during open and laparoscopic distal pancreatectomy

Annals of Gastroenterological Surgery, EarlyView.
This study showed that estimated BL (e‐BL) was significantly greater than intraoperative BL(i‐BL) in cases of laparoscopic distal pancreatectomy (LDP), and that e‐BL was significantly less than i‐BL in cases of open DP (ODP), only among patients with pancreatic cancer.

Surpassing the Human Accuracy: Detecting Gallbladder Cancer from USG Images with Curriculum Learning [PDF]

arXiv, 2022
We explore the potential of CNN-based models for gallbladder cancer (GBC) detection from ultrasound (USG) images as no prior study is known. USG is the most common diagnostic modality for GB diseases due to its low cost and accessibility. However, USG images are challenging to analyze due to low image quality, noise, and varying viewpoints due to the ...

Doubly robust machine learning for an instrumental variable study of surgical care for cholecystitis [PDF]

arXiv, 2023
Comparative effectiveness research frequently employs the instrumental variable design since randomized trials can be infeasible for many reasons. In this study, we investigate and compare treatments for emergency cholecystitis -- inflammation of the gallbladder.
