Chronic adnexal torsion: An under-recognized disease entity.

Objective: To clarify the incidence, clinical background and surgical characteristics of chronic adnexal torsion in comparison to acute adnexal torsion.

Study Design: The patients were divided into three categories based on the period from the onset of symptoms to surgical management: acute (≤24h), subacute (2days) and chronic adnexal torsions (≥3days). Cases, in which the onset of symptoms was unspecified, were included in the chronic adnexal torsion group.

Portomesenteric Vein Thrombosis After Excision of Parasitic Peritoneal Myomas.

An enlargement of multiple asymptomatic pelvic masses was detected during a regular checkup of a 39-year-old woman. Twelve years earlier, she had undergone laparoscopic-assisted myomectomy, at which time an uncontained manual extraction of a posterior intramural myoma was performed. This was followed by 2 uneventful cesarean deliveries after spontaneous conceptions.

Multi-institutional prospective feasibility study to explore tolerability and efficacy of oral nutritional supplements for patients with gastric cancer undergoing gastrectomy (CCOG1301).

Background: Postoperative malnutrition after gastrectomy is deemed inevitable, which could have prejudicial influence on survival for gastric cancer patients. A prospective feasibility study was conducted to evaluate the efficacy of postoperative oral nutritional supplements.

Methods: Stage I-III gastric cancer patients who underwent distal or total gastrectomy received oral administration of Racol NF (Otsuka Pharmaceutical Factory, Japan), a liquid enteral nutritional formula, as a supplement to regular meals.

Background: Advantages of neoadjuvant chemotherapy combined with monoclonal antibodies for treating patients with resectable colorectal cancer liver metastasis (CLM) have not been established. The purpose of this study was to evaluate the efficacy and safety of oxaliplatin-based regimen (FOLFOX or XELOX) plus monoclonal antibodies (cetuximab or bevacizumab) treatment in patients with resectable CLM.

Methods: A single-arm, open-label, multicenter, phase II trial was conducted for patients aged ≥ 20 years with resectable and untreated CLM.

Obesity-related changes in clinical parameters and conditions in a longitudinal population-based epidemiological study.

Objectives: The purpose of the present study was to examine the association of body mass index (BMI) or obesity with various clinical parameters and conditions in a longitudinal population-based epidemiological study in Japan.

Methods: Study subjects comprised 6027 community-dwelling individuals who were recruited to the Inabe Health and Longevity Study, a longitudinal genetic epidemiological study of atherosclerotic, cardiovascular, and metabolic diseases. Obesity was defined as BMI ≥25kg/m.

Near-infrared indocyanine dye permits real-time characterization of both venous and lymphatic circulation.

We investigated the optical properties of a near-infrared (NIR) fluorochrome, di-β-cyclodextrin-binding indocyanine derivative (TK-1), and its pharmacokinetic differences with indocyanine green (ICG). TK-1 was designed to have hydrophilic cyclodextrin molecules and, thus, for higher water solubility and smaller particle sizes than the plasma protein-bound ICG. We compared optical properties such as the absorption and fluorescence spectra, quantum yield, and photostability between both dyes in vitro.

Two cases of paragonimiasis westermani diagnosed after eosinophilic pleural effusion-induced hydropneumothorax.

Our hospital is located in the Tono region in the southeastern district of Gifu Prefecture in which there are forests and inhabitants who still hunt and eat game meat. Therefore, boar meat increases the risk of contracting paragonimiasis. We treated two patients who were infected by Paragonimus westermani after eating boar meat.

Predictors of outcomes in patients undergoing covered and uncovered self-expandable metal stent placement for malignant gastric outlet obstruction: a multicenter study.

Background And Aims: Uncovered self-expandable metal stents (U-SEMSs) and covered self-expandable metal stents (C-SEMSs) are available for palliative therapy for malignant gastric outlet obstruction (GOO). However, clinical differences and indications between the 2 types of SEMSs have not been elucidated.

Methods: We retrospectively compared 126 patients with U-SEMS and 126 patients with C-SEMSs with regard to clinical outcome and factors predictive of clinical improvement after SEMSs placement.

Gasless single-port laparoscopic-assisted vaginal hysterectomy for large uteri weighing 500g or more.

Objective: To evaluate the safety and feasibility of gasless transumbilical single-port laparoscopic-assisted vaginal hysterectomy (LAVH) for the management of large uteri weighing 500g or more.

Study Design: We conducted a retrospective comparative study of women with large uteri, each undergoing gasless multi-port or single-port LAVH. Preoperatively, gonadotropin-releasing hormone agonist was administered and autologous blood was donated except for cases requiring immediate surgery.

Bleeding risk of endoscopic ultrasound-guided fine-needle aspiration in patients undergoing antithrombotic therapy.

Objectives: Bleeding events related to endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) are rare. However, for patients treated with antithrombotic agents, the bleeding risk of EUS-FNA is uncertain. Hence, the aim of this study was to assess the bleeding event rate associated with EUS-FNA in patients receiving antithrombotic treatment.

[Incomplete Surgical Resection of a Right Ventricular Hemangioma with Asymptomatic Gradual Enlargement for more than a Decade;Report of a Case].

We encountered a case of a cardiac hemangioma protruding into the inner cavity of the right ventricle from the right ventricular free wall. The tumor gradually enlarged over 11 years (from 35 mm to 78mm) without presenting any symptoms. However, when it extended to the right ventricular outflow tract, non-sustained ventricular tachycardia occurred, and emergency surgery was required.

Feasibility of the placement of a novel 6-mm diameter threaded fully covered self-expandable metal stent for malignant hilar biliary obstructions (with videos).

Background And Aims: Uncovered self-expandable metal stents (USEMSs) are used to treat unresectable malignant hilar biliary obstructions (MHBOs). However, ingrowth is not prevented, and reintervention is often troublesome. A novel 6-mm threaded fully covered self-expandable metal stent (T-FCSEMS) is available that may mitigate these issues.
