A Retrospective Study About the Effectiveness of Anastomosis With a Polyglycolic Acid Sheet in Colorectal Cancer.

Introduction Anastomotic leakage is a serious complication in colon and rectal cancer surgeries, contributing to increased mortality rates and extended hospital stays. Despite various preventive measures, including intraoperative assessments and transanal drains, the incidence of anastomotic leakage remains a significant concern. This study investigates the potential efficacy of polyglycolic acid (PGA) sheets in reducing anastomotic leakage rates in gastrointestinal surgeries.

Long-term activation of anti-tumor immunity in pancreatic cancer by a p53-expressing telomerase-specific oncolytic adenovirus.

Background: Pancreatic cancer is an aggressive, immunologically "cold" tumor. Oncolytic virotherapy is a promising treatment to overcome this problem. We developed a telomerase-specific oncolytic adenovirus armed with p53 gene (OBP-702).

[A Case of Transcatheter Arterial Chemoembolization and Surgical Resection of Left 7th Rib Metastasis after Surgery for Hepatocellular Carcinoma].

The patient was an 81-year-old man. After a liver posterior segmentectomy for hepatocellular carcinoma, a painful bulge was observed in the left anterior thoracic region during a routine outpatient visit. Elevated tumor markers and contrast- enhanced CT scan revealed a mass with contrast effect in the left 7th rib.

Osteoradionecrosis of the occipitocervical junction: A rare case of C1 anterior arch disruption.

We report the case of a 57-year-old man who developed osteoradionecrosis (ORN) at the occipitocervical (OC) junction after radiation therapy for nasopharyngeal carcinoma. During soft-tissue debridement using a nasopharyngeal endoscope, the anterior arch of the atlas (AAA) was spontaneously disrupted, which was later spat out. Radiographic examination revealed complete disruption of the AAA that caused OC instability.

Axillary Lymph Node Swelling After COVID-19 Booster Vaccination: Japanese Case Report and Literature Review.

Background/aim: COVID-19 has been a global pandemic for more than 2 years, and vaccination against COVID-19 using an mRNA vaccine is widespread. The COVID-19 vaccination can cause specific side-effects, such as axillary lymph node swelling; therefore, breast oncologists should pay attention to such occurrences. Initially, only two COVID-19 vaccinations were planned; however, in some countries third or fourth vaccines have been administered.

Timing and Duration of Axillary Lymph Node Swelling After COVID-19 Vaccination: Japanese Case Report and Literature Review.

Background/aim: COVID-19 vaccination is now performed in most of the world to limit the spread of the disease. The first mRNA vaccine was approved in clinical settings and has specific side effects including axillary lymph node swelling, which can be misdiagnosed as breast cancer metastasis. The timing of axillary lymph node swelling and its duration are unclear.

COVID-19 Screening of Breast Cancer Patients During Treatment: A Single Center Experience in Japan.

Background/aim: Breast cancer treatment mainly involves interventional methods such as surgical resection and chemotherapy. How to best perform these treatments during the COVID-19 pandemic remains to be established.

Patients And Methods: Patients with breast cancer who received SARS-CoV-2 PCR screening before cancer treatment from December 2020 to April 2021 were included.

Extensive Organ Necrosis After Thoracic Endovascular Aortic Repair for Thoracic Aortic Aneurysm: A Report of the Usefulness of Laparoscopic Indocyanine Green Intraoperative Blood Flow Assessment.

An 85-year-old man underwent thoracic endovascular aortic repair (TEVAR) for a thoracic aortic aneurysm (TAA). The day after TEVAR, the patient complained of abdominal pain. Blood tests showed lactic acidosis.

Axillary Lymph Node Swelling Mimicking Breast Cancer Metastasis After COVID-19 Vaccination: A Japanese Case Report and Literature Review.

Background/aim: COVID-19 started to spread as a pandemic in December 2019 and COVID-19 vaccination has been initiated worldwide. The efficacy of vaccination has been scientifically proven, but it might cause axillary lymph node swelling. To diagnose patients with axillary lymph node swelling caused by COVID-19 vaccination, we herein reviewed existing literature on this symptom.

Feasibility of a fast-track randomized controlled trial of cell-free and concentrated ascites reinfusion therapy for patients with refractory malignant ascites.

Background: Malignant ascites often causes discomfort in advanced cancer patients. Paracentesis is the most common treatment modality, but it requires frequently repeated treatment. Cell-free and concentrated ascites reinfusion therapy (CART) may prolong the paracentesis interval, but controlled trials are lacking.

Effect of early enteral nutrition on critical care outcomes in patients with acute ischemic stroke.

Objective: Stroke-associated pneumonia (SAP) is a comorbidity of ischemic stroke related to clinical outcomes. Early enteral nutrition (EEN; within 48 hours) reduces the incidence of infection and length of intensive care unit (ICU)/hospital stay. The relationship between EEN and critical care outcomes, including SAP, in patients with ischemic stroke has been insufficiently studied.

Introduction: We report a case of a patient who underwent laparoscopic surgery for intestinal obstruction caused by the mesodiverticular band of Meckel's diverticulum, with pathological specimens showing ectopic pancreas.

Presentation Of Case: A 56-year-old woman presented to our hospital with complaints of abdominal pain and vomiting. Upon close examination, we suspected strangulated intestinal obstruction, and performed an emergency surgery.

Colony Formation in Three Species of the Family Scenedesmaceae (Desmodesmus subspicatus, Scenedesmus Acutus, Tetradesmus Dimorphus) Exposed to Sodium Dodecyl Sulfate and its Interference with Grazing of DAPHNIA Galeata.

By mimicking the info-chemicals emitted by grazers, the common anionic surfactant sodium dodecyl sulfate (SDS) can induce colony formation in the green algal genus Scenedesmus at environmentally relevant concentrations. The morphometric effects can hinder the feeding efficiency of grazers, reducing energy flow along the pelagic food chain from Scenedesmus to consumers. Despite this potential ecological risk, few studies exist on whether the SDS-triggered induction of colonies is common in other species of the family Scenedesmaceae.

Transcatheter arterial embolization for hemorrhagic rupture of a simple hepatic cyst: A case report.

Hemorrhagic rupture is a very rare and life-threatening hepatic cyst complication. Several treatment methods have been used for hepatic cyst hemorrhage and/or rupture; however, transcatheter arterial embolization for hepatic cyst hemorrhage has been poorly documented. An 80-year-old man receiving dual antiplatelet therapy was diagnosed with hemorrhagic rupture of a hepatic cyst.

BACKGROUND Juvenile polyposis syndrome is an uncommon, autosomal-dominant hereditary disease that is distinguished by multiple polyps in the stomach or intestinal tract. It is associated with a high risk of malignancy. Pathogenic variants in SMAD4 or BMPR1A account for 40% of all cases.

Lumbar artery aneurysm complicated by a fistula between the aneurysm and the duodenum in a patient with Leriche syndrome: A case report.

Introduction: Various collateral pathways maintain blood flow to the lower extremities in patients with Leriche syndrome. The occurrence of true aneurysms in the lumbar artery-a component of an extensive collateral circulation network in patients with Leriche syndrome-is extremely rare.

Presentation Of Case: A 73-year-old man with Leriche syndrome was diagnosed with lumbar artery aneurysm complicated by a duodenal fistula.

Surgical Resection of Anastomotic Stenosis after Rectal Cancer Surgery Using a Circular Stapler and Colostomy with Double Orifice.

The double stapling technique has greatly facilitated intestinal reconstruction, particularly for anastomosis after anterior resection. However, anastomotic stenosis may occur, which sometimes requires surgical treatment. Redo surgery with reresection and reanastomosis presents a high risk of complications.

Iatrogenic esophageal perforation that could be treated indirectly by cervical esophagostomy and laparoscopic surgery.

Introduction: Successful nonoperative management has been reported for esophageal perforation; however, some cases require surgery.

Case Presentation: We presented the case of an 85-year-old woman with iatrogenic thoracic esophageal perforation in whom primary repair or resection of the perforated esophagus was difficult because she was elderly and had severe aortic valve stenosis. Therefore, we selected a two-stage surgery; laparoscopic gastrostomy, jejunostomy, posterior mediastinal drainage, and cervical esophagostomy were performed.
