Preoperative diagnosis of adhesion severity between the abdominal wall and intestinal tract with novel abdominal ultrasound methodology to enhance surgical safety.

Background: Adhesions between the abdominal wall and intestinal tract from previous surgeries can complicate reoperations; however, predicting the extent of adhesions preoperatively is difficult. This study aimed to develop a straightforward approach for predicting adhesion severity using a novel abdominal ultrasound technique that quantifies the displacement of motion vectors of two organs to enhance surgical safety. The efficacy of this methodology was assessed experimentally and clinically.

[Examination of Factors Related to Walking Ability in Patients with Abdominal Cancer].

It has been reported that preoperative rehabilitation reduces the risk of postoperative complications. We examined the factors impacting the efficacy of preoperative rehabilitation. Forty-three cancer patients who underwent abdominal surgery after preoperative rehabilitation at our hospital were assessed".

Liver stiffness measured by virtual touch quantification predicts the occurrence of posthepatectomy refractory ascites in patients with hepatocellular carcinoma.

Purpose: This study assessed the significance of measuring liver stiffness using virtual touch quantification before hepatectomy to predict posthepatectomy refractory ascites.

Methods: A total of 267 patients with hepatocellular carcinoma who underwent hepatectomy were prospectively analyzed. Liver stiffness was defined as the median value of the virtual touch quantification (Vs; m/s) by acoustic radio-force-impulse-based virtual touch.

Hepatectomy using a novel cart-based indocyanine green fluorescence imaging system.

Indocyanine green (ICG) fluorescence has been used effectively in imaging for locating hepatic tumors and evaluating hepatic segmentation. We report our initial experience of performing hepatic resection using the novel cart-based ICG fluorescence device LIGHTVISION. This device has several promising features, including the fact that there is no need to switch off the room light, it has hands-free operability, and it can be located away from the workspace to facilitate a good field of vision.

Immunohistochemical characterization of cancer-associated fibroblasts at the primary sites and in the metastatic lymph nodes of human intrahepatic cholangiocarcinoma.

Cancer-associated fibroblasts (CAFs) are an important constituent of the cancer stroma. In intrahepatic cholangiocarcinoma (ICC), the features of CAFs at the primary site and in the metastatic lymph nodes (Met-LNs) and their origin have been unclear. In the present study, we characterized CAFs at the primary site (n = 42) and in the Met-LNs (n = 10) of human ICC by immunohistochemistry using potential molecular markers of CAFs, portal fibroblasts (PFs), hepatic stellate cells (HSCs), and bone marrow-derived fibrocytes (BMDFs).
