Longitudinal analysis of serum intestinal fatty acid-binding protein in a patient with non-occlusive mesenteric ischemia following brachial plexus block-induced hypotension: a case study.

Intestinal fatty acid-binding protein (I-FABP) is a promising biomarker for small-bowel ischemia including non-occlusive mesenteric ischemia (NOMI). A 75-year-old woman with diabetic nephropathy sustained a distal radius fracture. Two days later, she underwent a brachial plexus block to facilitate orthopedic surgery, which resulted in hypotension.

Combined pancreaticoduodenectomy for advanced gallbladder cancer: Indications, surgical outcomes, and limitations.

Background: This study aimed to elucidate the clinical value of combined pancreaticoduodenectomy (PD) for advanced gallbladder cancer according to the mode of cancer spread in the pancreaticoduodenal region.

Methods: Patients who underwent combined PD for advanced gallbladder cancer were retrospectively reviewed. The mode of cancer spread in the pancreaticoduodenal region was defined as involvement of peripancreatic organs/structures alone, peripancreatic nodal metastasis alone, or both.

Extent of regional lymphadenectomy and number-based nodal classification for non-ampullary duodenal adenocarcinoma.

Background: This study aimed to evaluate the adequate extent of regional lymphadenectomy according to tumor location and the impact of number-based nodal classification on survival in patients with non-ampullary duodenal adenocarcinoma (NADAC).

Methods: A total of 85 patients with NADAC who underwent surgery were enrolled. The frequency of metastasis was calculated for each node group in the respective tumor locations for 63 patients who underwent lymphadenectomy for pT2-pT4 tumor.

Totally laparoscopic resection of right-sided colon cancer using transvaginal specimen extraction with a 10-mm-long abdominal incision.

Background: Natural orifice specimen extraction (NOSE) has been developed as a means of decreasing the incidence of surgical wound complications. We refined the procedure for totally laparoscopic colectomy with transvaginal specimen extraction using the reduced port surgery technique with the ultimate goal of attenuating damage to the abdominal wall. We herein report this innovative technique and its short- and long-term outcomes.

Outcomes of lung metastasis from pancreatic cancer: A nationwide multicenter analysis.

Background: Although distant metastasis from pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis, some single center studies reported that lung metastasis has a favorable prognosis. The aim of this study is to evaluate the prognostic value of site-specific metastasis after pancreatectomy for PDAC, with a focus on lung metastasis.

Methods: Data from 117 cases of lung metastasis after pancreatectomy were collected retrospectively from 23 institutions in Japan.
