An inclusion complex, K{[Ni(maleonitriledithiolate)]@(β-CD)} (), was constructed from and two β-CDs. The anion guest Ni complex included a host cavity, constructed using two β-CDs, and the Ni atom of the anion was located between the two hydrophilic primary rims.

Successful robotic-assisted resection of an esophageal duplication cyst in the upper thoracic esophagus: A case report with surgical video.

Esophageal duplication cysts are rare congenital noncancerous growths. Symptoms of this disease are reported to be asymptomatic in approximately 70% but include respiratory symptoms such as coughing and difficulty breathing. Minimally invasive removal of these cysts without esophagectomy is typically recommended.

How do we prevent severe intra-abdominal infectious complications following minimally invasive gastrectomy for cancer? The usefulness of a novel marker using computed tomography images (minimum umbilicus-vertebra diameter) and robotic surgery.

Background: Intra-abdominal infectious complications (IAICs) following minimally invasive gastrectomy (MIG) for cancer sometimes worsen short- and long-term outcomes. In this study, we focused on the minimum umbilicus-vertebra diameter (MUVD) in preoperative computed tomography (CT) images and robotic surgery to prevent severe IAIC occurrence.

Background: The efficacy of robotic gastrectomy (RG) on postoperative complications in patients with gastric cancer (GC) is unclear in terms of the volume of intra-abdominal fat tissue.

Patients And Methods: We enrolled 403 patients with GC who had minimally invasive surgery between January 2015 and July 2022. During this time, 197 RG and 206 laparoscopic gastrectomies (LG) were performed on the study participants.

Usefulness of intraoperative ultrasound examination for laparoscopic right-side colon cancer surgery: a propensity score-matched study.

Complete mesocolic excision (CME) with central vascular ligation (CVL) in laparoscopic surgery for right-sided colon cancer (RSCC) requires a precise understanding of the vascular anatomy. The efficacy of intraoperative ultrasound (IUS) in the identification of blood vessels for RSCC surgery was not evaluated. The aim of this study was to compare the intraoperative and short-term outcomes of CME with CVL with or without IUS by laparoscopic surgery for RSCC.

The effect of unilateral chest drainage for transpulmonary pressure during mechanical ventilation.

Introduction: Chest tube drainage is usually performed through an underwater seal at a level of 10-20 cmHO. Based on the definition of transpulmonary pressure, continuous chest drainage creates continuous negative pressure, decreasing pleural surface pressure and increasing transpulmonary pressure. We investigated how unilateral chest drainage could affect the tidal volume or driving pressure during mandatory mechanical ventilation.

The Cancer Cachexia Index Can Be Used to Prognostically Predict Patients with Gastric Cancer Undergoing Gastrectomy.

Introduction: Cancer cachexia occurs in cancer patients more frequently as the cancer progresses, with a negative impact on treatment outcomes. In this study, we sought to clarify the clinical impact of a cancer cachexia index (CXI) in patients with gastric cancer (GC) undergoing gastrectomy.

Methods: Between January 2013 and December 2018, we reviewed data from 556 patients treated for GC at our hospital.

Impact of a circular powered stapler on preventing anastomotic leakage in patients with left-sided colorectal cancer: a retrospective study.

Background: The powered circular stapler, which was developed with the aim of providing reliable and reproducible anastomosis, provides complete anastomosis, resulting in a reduced risk of anastomotic leakage. The aim of this study was to compare the incidence of anastomotic leakage between a conventional manual circular stapler (MCS) and the ECHELON CIRCULAR™ Powered Stapler (ECPS) in patients with left-sided colorectal cancer who underwent anastomosis with the double stapling technique.

Methods: A total of 187 patients with left-sided colorectal cancer who underwent anastomosis with the double stapling technique with a conventional MCS or the ECPS during surgery at Osaka City University Hospital between January 2016 and July 2022 were enrolled in this study.

Impact of Preoperative Nutritional Status on Long-term Survival in Patients With Stage I-III Colorectal Cancer.

Background/aim: In addition to oncological and treatment factors, the outcomes of cancer treatment are greatly influenced by host factors, such as the nutritional status. The aim of this study was to evaluate the association between the preoperative nutritional status and the prognosis of colorectal cancer patients using three nutritional indices.

Patients And Methods: The target cohort consisted of 529 patients with stage I-III colorectal cancer, who underwent curative surgery between January 2015 and December 2019.

Efficacy of the polyglycolic acid sheet for preventing anastomotic leakage in double-stapling technique anastomosis for left-sided colon or rectal cancer surgery: a propensity score-matched study.

Background: To prevent anastomotic leakage in patients with left-sided colorectal cancer who underwent double-stapling technique (DST) anastomosis, we investigated a new method: DST anastomosis with a polyglycolic acid (PGA) sheet. This procedure has been shown to have the potential to decrease the rate of anastomotic leakage. However, due to the small number of cases enrolled in our previous study, it was not possible to compare the outcomes of the new and conventional procedures.

Significance of the Prognostic Immune and Nutritional Index in Patients With Stage I-III Colorectal Cancer.

Background/aim: Recently, the prognostic immune and nutritional index (PINI), which is calculated from the peripheral monocyte count and serum albumin level, has been reported to be useful as a prognostic marker in Korean and Chinese patients with colorectal cancer. The present study therefore examined the usefulness of the PINI as a marker for predicting the prognosis in Japanese colorectal cancer patients.

Patients And Methods: A total of 529 patients who underwent curative surgery for stage I-III colorectal cancer between January 2015 and December 2019 were enrolled in this study.
