Finding the Right Hepatic Artery Branching from the Gastroduodenal Artery in a Patient Undergoing Gastrectomy: A Rare Case of an Anatomical Variant.

Numerous vascular anomalies of the hepatic artery have been reported. Protection of the hepatic arterial supply is important during gastrectomy. We herein report a case in which an anatomical variant of the hepatic artery was discovered in a patient undergoing laparoscopic distal gastrectomy with D1+ lymph node dissection for early gastric cancer.

New Treatment Modalities for Colorectal Cancer Through Simultaneous Suppression of FSP1 and GPX4.

Background/aim: Ferroptosis is a nonapoptotic type of cell death that is dependent on iron and involves the accumulation of reactive oxygen species. Ferroptosis suppressor protein 1 (FSP1) and glutathione peroxidase 4 (GPX4) are ferroptosis regulators that inhibit ferroptosis through independent pathways. This study assessed the prognostic value of GPX4 and FSP1 expression in colorectal cancer (CRC).

Exosomal miR-493 suppresses MAD2L1 and induces chemoresistance to intraperitoneal paclitaxel therapy in gastric cancer patients with peritoneal metastasis.

Intraperitoneal (IP) chemotherapy with paclitaxel (PTX) for gastric cancer (GC) with peritoneal metastasis (PM) is considered a promising treatment approach, however, there are no useful biomarkers to predict the efficacy of IP therapy. We examined the association between intra-peritoneal exosomes, particularly exosomal micro-RNAs (exo-miRNAs), and IP-chemo sensitivity. MKN45 cells that were cultured with intra-peritoneal exosomes from patients who did not respond to IP therapy with PTX (IP group) exhibited resistance to PTX compared with exosomes from responding patients (IP group) (p = 0.

Methods: This study included 301 patients with a histopathological diagnosis of gastric adenocarcinoma who underwent curative surgery.

Right thoracoscopic resection in the supine position for recurrent pretracheal lymph nodes after esophagectomy.

Mediastinal lymph node recurrence is often observed following esophageal cancer surgery; however, no treatment has been established for the same. Surgical resection is often considered for cases of recurrence in a single lymph node region, although the procedures and approaches vary depending on the recurrence site. Right thoracoscopic resection is rarely opted for owing to its high surgical difficulty.

Combined analysis of preoperative and postoperative lymphocyte-C-reactive protein ratio precisely predicts outcomes of patients with gastric cancer.

Background: The systemic inflammatory response resulting from the complex interactions between cancer and the host plays an important role in cancer development. Recently, the lymphocyte-C-reactive protein ratio (LCR), which is a hematological and biochemical marker that reflects the systemic inflammatory response and nutritional status, has been reported to be associated with poor survival. Similar results were observed in patients with certain cancer types.

Laparoscopic cholecystectomy after percutaneous transhepatic gallbladder drainage for acute cholecystitis in a patient with a left ventricle assist device: A case report and brief review of the literature (with video).

For acute cholecystitis in patients with left ventricular assist devices, the use of percutaneous transhepatic gallbladder drainage to calm inflammation before planned laparoscopic cholecystectomy may be helpful in safely adjusting anticoagulation and in performing safe laparoscopic cholecystectomy, as demonstrated in this case.

Circular stapling anastomosis with indocyanine green fluorescence imaging for cervical esophagogastric anastomosis after thoracoscopic esophagectomy: a propensity score-matched analysis.

Background: Thoracoscopic esophagectomy has been extensively used worldwide as a curative surgery for patients with esophageal cancer; however, complications such as anastomotic leakage and stenosis remain a major concern. Therefore, the objective of this study was to evaluate the efficacy of circular stapling anastomosis with indocyanine green (ICG) fluorescence imaging, which was standardized for cervical esophagogastric anastomosis after thoracoscopic esophagectomy.

Methods: Altogether, 121 patients with esophageal cancer who underwent thoracoscopic esophagectomy with radical lymph node dissection and cervical esophagogastric anastomosis from November 2009 to December 2020 at Tottori University Hospital were enrolled in this study.

A patient was found to have an intra-abdominal cyst on fetal ultrasonography and was born at 37 weeks of gestation with a body weight of 2,636 g. Abdominal distension and repeated vomiting appeared 2 days after birth.

[A Case of Cervical Esophageal Cancer with Lymph Node Recurrence Three Times after Definitive Chemoradiotherapy].

A 56-years old man was diagnosed with cervical esophageal cancer with lymph node metastasis. After definitive chemoradiotherapy as the first-line therapy, complete response(CR)was obtained. One year and 3 months after the therapy, lymph node dissection and postoperative chemotherapy was performed for the lymph node metastases of the left neck and axillary lymph node.

Impact of skeletal muscle mass in patients with unresectable gastric cancer who received palliative first-line chemotherapy based on 5-fluorouracil.

Background: The mortality rate of patients with unresectable gastric cancer (UGC) has decreased with the development of chemotherapies and surgical techniques. However, the survival rate remains low. We retrospectively examined the prognostic significance of the pretreatment skeletal muscle mass index (SMI) and nutritional and inflammatory factors in patients with UGC.

Infiltration of CD204-overexpressing Macrophages Contributes to the Progression of Stage II and III Colorectal Cancer.

Background/aim: M1 macrophages have antitumour effects, while M2 macrophages promote tumour proliferation and invasion. The clinical significance of the M2-specific marker CD204 has not been elucidated in colorectal cancer (CRC). We investigated the prognostic significance of CD204- and CD68-positivity in specimens from patients with CRC and examined the effects of M2 polarized-macrophages on the proliferative and invasive potentials of CRC cell lines in vitro.

Platelet-to-Lymphocyte Ratio Multiplied by the Cytokeratin-19 Fragment Level as a Predictor of Pathological Response to Neoadjuvant Chemotherapy in Esophageal Squamous Cell Carcinoma.

Background: The standard treatment for resectable advanced esophageal squamous cell carcinoma in Japan is surgery followed by neoadjuvant chemotherapy, and it is important to predict the effect of neoadjuvant chemotherapy before treatment. Therefore, this study aims to extract conventional blood examination data, such as tumor markers and/or inflammatory/nutritional index levels, that can predict the pathological response of patients with esophageal squamous cell carcinoma to neoadjuvant chemotherapy.

Methods: We retrospectively analyzed the medical records of 66 patients with thoracic esophageal squamous cell carcinoma who received neoadjuvant chemotherapy, followed by curative esophagectomy at Tottori University Hospital between June 2009 and December 2019.
