Methods: The subjects were 30 patients who underwent training between January 2022 and January 2023 and who could be evaluated 3 times. The first step of the program was to diagnose frailty and sarcopenia.

Usefulness of the Primary Tumor Standardized Uptake Value of Iodine-123 Metaiodobenzylguanidine for Predicting Metastatic Potential in Pheochromocytoma and Paraganglioma.

Purpose: To examine the usefulness of semi-quantitative analysis using the standardized uptake value (SUV) of iodine-123 metaiodobenzylguanidine ([I]-MIBG) for predicting metastatic potential in patients with pheochromocytoma (PHEO) and paraganglioma (PGL).

Procedures: This study included 18 PHEO and 2 PGL patients. [I]-MIBG visibility and SUV-related parameters (SUVmax, SUVmean, tumor volume of [I]-MIBG uptake [TV_MIBG], and total lesion [I]-MIBG uptake) were compared with the pathological grading obtained using the Pheochromocytoma of the Adrenal Gland Scaled Score (PASS) and the Grading System for Adrenal Pheochromocytoma and Paraganglioma (GAPP), which are used to predict metastatic potential.

The polymyxin-B direct hemoperfusion OPTimal Initiation timing with Catecholamine PMX-OPTIC study: A multicenter retrospective observational study.

Background: Polymyxin-B direct hemoperfusion (PMX-DHP) is an endotoxin adsorption column-based blood purification therapy. Since one of the most potent effects of PMX-DHP is blood pressure elevations, it may be the most effective when it is introduced at the time when the need for vasopressors is the greatest, which, in turn, may reduce mortality.

Methods: A multicenter retrospective study was conducted at 24 ICUs in Japan.

Applying deep learning-based ensemble model to [F]-FDG-PET-radiomic features for differentiating benign from malignant parotid gland diseases.

Objectives: To develop and identify machine learning (ML) models using pretreatment 2-deoxy-2-[F]fluoro-D-glucose ([F]-FDG)-positron emission tomography (PET)-based radiomic features to differentiate benign from malignant parotid gland diseases (PGDs).

Materials And Methods: This retrospective study included 62 patients with 63 PGDs who underwent pretreatment [F]-FDG-PET/computed tomography (CT). The lesions were assigned to the training (n = 44) and testing (n = 19) cohorts.

Robotic vs. laparoscopic distal gastrectomy for gastric cancer: A propensity score-matched retrospective comparative study at a single institution.

Background: Although robotic surgery is becoming more widespread worldwide, it is still in its infancy. This study aimed to confirm the safety and feasibility of the induction of robotic-assisted gastric surgery at a local hospital.

Methods: For five years, between 2016 and 2020, 42 laparoscopic and 71 robotic distal gastrectomies were performed at the same institution.

Poor short-term outcomes for prognostic high-risk patients with chronic limb-threatening ischemia undergoing endovascular therapy.

Background: The prognosis of chronic limb-threatening ischemia (CLTI) is poor, with an expected life expectancy of 2 or more years, which significantly influences treatment decisions. However, death may occur at the early stages of treatment for wound healing, and aggressive treatment may limit the quality of life of such patients. In patients with CLTI undergoing endovascular therapy (EVT), the Wound, Ischemia, and foot Infection (WIfI) clinical stage, male sex, older age, non-ambulatory status, low body mass index, and dialysis have been reported as predictors of mortality risk.

Case Report: Resolution of remitting seronegative symmetrical synovitis with pitting edema during nivolumab therapy for gastric cancer.

The anti-programmed cell death-1 (PD-1) antibody nivolumab has been shown to significantly prolong the survival of patients with unresectable advanced or recurrent gastric cancer (AGC). However, immune-related adverse events (irAEs), which show different profiles from those of cytotoxic agents or conventional molecular-targeted drugs including tyrosine kinase inhibitors, have been reported. Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare autoimmune disorder with acute-onset, rheumatoid factor-negative, symmetric synovitis associated with limb edema observed in elderly persons.

A case of recurrent epiphrenic esophageal diverticulum treated with lower esophagogastric resection and interstitial jejunal reconstruction.

The patient is a 60-year-old female with a history of multiple times of recurrences of an esophageal diverticulum. She was referred for a diagnosis of persistent dysphagia and vomiting. Balloon dilation did not improve the symptoms; thus, she was referred for surgery.

Ethnic Differences in Western and Asian Sacroiliac Joint Anatomy for Surgical Planning of Minimally Invasive Sacroiliac Joint Fusion.

Pain originating in the sacroiliac joint (SIJ) is a contributor to chronic lower back pain. Studies on minimally invasive SIJ fusion for chronic pain have been performed in Western populations. Given the shorter stature of Asian populations compared with Western populations, questions can be raised regarding the suitability of the procedure in Asian patients.

Metachronous triple cancers of the stomach, duodenum and rectum in a patient with familial adenomatous polyposis.

Familial adenomatous polyposis (FAP) is an autosomal dominant disorder characterized by the presence of at least 100 adenomatous polyps in the colon and rectum. The risk of upper gastrointestinal tumors is relatively high in patients with FAP, but a case of triple cancers has not been reported in the literature. We herein report a case of metachronous triple cancers of the stomach, duodenum and rectum in a patient with FAP.

A case report of anaplastic carcinoma with osteoclast-like giant cells arising in the pancreatic body.

The patient is a 58-year-old woman. She was referred to our hospital following a computed tomography scan that revealed a 2-cm tumor-like lesion in the pancreatic body. Endoscopic ultrasound fine-needle aspiration examination revealed a suspected undifferentiated carcinoma with pleomorphic type.

A case of post-operative stenosis caused by colonic ischemia after low anterior resection for rectal cancer, followed by delayed colo-anal anastomosis.

Cases of delayed colo-anal anastomosis (DCAA) are currently reported instead of the colo-anal anastomosis with a protective loop ileostomy for rectal cancer. Post-operative colonic ischemia is considered as one of the serious complications of colorectal resection. Although indication of DCAA should be carefully selected, we experienced a case of post-operative stenosis caused by colonic ischemia after low anterior resection for rectal cancer, followed by this procedure.

Behçet's disease (BD) is a rare chronic inflammatory disease associated with systemic vasculitis. Involvement of the nervous system in BD is called neuro-BD (NBD). Epilepsy related to NBD is uncommon but responds well to anti-epileptic drugs.

Evaluating the Khorana risk score of gastrointestinal cancer patients during initial chemotherapy as a predictor of patient mortality: A retrospective study.

Background: The Khorana risk score (KRS) has been recommended for predicting the incidence of cancer-associated thrombosis (CAT). However, it has been reported KRS was not useful in predicting CAT, but rather in predicting death by setting high scores for the primary tumor site or a low prevalence of severe obesity.

Methods: A total of 260 consecutive patients with no history of thrombosis and who started initial chemotherapy for gastrointestinal cancer from January 2017 to December 2018 at our hospital were divided into three groups according to KRS; they were observed until December 2019 [122 patients (46.

A case of emergency pancreatoduodenectomy for bleeding from the duodenal mucosa due to arteriovenous malformation of the pancreatic head.

A rare case of bleeding from the duodenal mucosa due to arteriovenous malformation of the pancreatic head is reported. Caution needs to be observed, then excision may be necessary since noninvasive treatment such as coil embolization is not enough for complete hemostasis when patient suddenly decompensates.
