Laparoscopic minor liver resection for hepatocellular carcinoma.

Background: Previous studies have suggested that laparoscopic liver resection for hepatocellular carcinoma is associated with lower postoperative complications compared with open liver resection.

Methods: We conducted a retrospective analysis of 109 hepatocellular carcinoma patients who underwent minor liver resection at a Japanese tertiary care hospital from November 2010 to December 2022.

Results: The laparoscopic liver resection group experienced significantly lower median intraoperative blood loss compared with the open liver resection group (P = 0.

Quality of life after total pancreatectomy with islet autotransplantation for chronic pancreatitis in Japan.

Background: Patients with chronic pancreatitis (CP) often have severe and intractable abdominal pain, leading to decreased quality of life (QOL), inability to work or attend school, and increased health care costs due to repeated emergency room visits and hospitalizations.

Methods: We evaluated the efficacy of total pancreatectomy and islet autotransplantation (TPIAT) in terms of pain control and QOL in CP patients treated at our center in Japan. To evaluate QOL, we used the Short-Form 36 Health Survey version 2 (SF-36v2 Standard, Japanese), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), and Quality of Life Questionnaire-Pancreatic Modification (QLQ-PAN28).

[Laparoscopic Right-Sided Colon Cancer Surgery Using Pancreas/Duodenum 3DCT(PDCT)].

Background And Purpose: The right colic artery(RCA)and gastrocolic trunk(GCT)traverse around the pancreas and duodenum and branch divergently, thus, complicating right-sided colon cancer surgery. The usefulness of pancreatic/duodenum 3DCT imaging(pancreas/duodenum CT: PDCT)for laparoscopic right-sided colon cancer surgery was investigated.

Patient And Method: The patient was a woman, in her 80's with 2 sites of ascending colon cancer:(1)A-C, cT4b(retroperitoneum) N2aM0, Stage Ⅲc;(2)A, cT3N1bM0, Stage Ⅲb.

Registration between 2D and 3D Ultrasound Images to Track Liver Blood Vessel Movement.

Background: For the accurate positioning of surgical tools, conventional intraoperative navigation systems have been developed to recognize the relationship between target positions and the tools. However, since an internal organ is deformed during the operation, registration between realtime two-dimensional (2D) ultrasound images and three-dimensional (3D) CT or MRI images is not always effective. Therefore, this study developed image registration between 2D and 3D ultrasound images considering deformation for tracking target vessel movement in the liver.

Preoperative neutrophil-to-lymphocyte ratio may contribute to the prediction of postoperative infectious complications in patients with acute appendicitis: a retrospective study.

Background: Several studies have assessed various clinical variables to identify risk factors for postoperative complications in patients with acute appendicitis. However, few studies have focused on the relationships between systemic inflammatory variables and postoperative complications in patients with acute appendicitis. We investigated the relationships between postoperative complications and systemic inflammatory variables, and assessed the clinical utility of these variables as predictors of postoperative complications in patients with acute appendicitis.
