The Usefulness of a Simple Classification for Bronchoscopic Findings for Diagnosis of Peripheral Pulmonary Tumour.

Background: Normal bronchial epithelium has been described in terms of transparency and smoothness. No studies have compared bronchoscopic and pathological findings in the identification of bronchial epithelium.

Objectives: This study aimed to classify bronchoscopic findings for peripheral pulmonary tumour (PPT) for accurate bronchoscopic diagnosis accounting for the presences of bronchial epithelium and bronchial stenosis using an ultrathin bronchoscope.

[A Case in Which the ICG Fluorography Was Useful for Detecting Minute Peritoneal Disseminations].

A 65-year-old man was emergently brought to our hospital because of rupture of 10 cm hepatocellular carcinoma(HCC) at left lobe in September 2019. He underwent selective transcatheter arterial embolization(TAE)for hemostasis. Enhanced computed tomography(CT)revealed one more 26 mm HCC at segment 8(S8)in addition to the ruptured HCC.

[A Case of Ileus Due to Colon Cancer with Non-Occlusive Mesenteric Ischemia].

Abdominal computed tomography(CT)revealed ileus due to sigmoid colon cancer in a 68-year-old man with abdominal pain, and endoscopic decompression using a transanal ileus tube was attempted. The blood test on the following day showed a marked increase in CRP 46.13mg/dL.

A case report: Feasibility of a near infrared ray vision system (Photo dynamic eye®) for the postoperative ischemic complication of gallbladder carcinoma.

Introduction: Radical resection with or without preserving extra-hepatic bile duct has shown similar prognoses for gallbladder carcinoma (GB ca), although aggressive resection is essential. In preserving bile duct, ischemic complications are serious, life-threatening serious problems. Correct evaluation of the blood flow to the biliary tract is crucial.

Case: Authentic multimodal therapy and liver resection for an initially unresectable intrahepatic cholangiocarcinoma.

Introduction: Although curative resection is an outstanding prognostic factor of intrahepatic cholangiocarcinoma (ICC), certain segments remain unresectable. The standard therapy for initially unresectable ICC is uncertain. In this case report, we reported the feasibility of multimodal chemotherapy and curative resection.

[A Case of Gastric GIST with Pathological Complete Response Achieved by Long-Term Chemotherapy with Imatinib Mesylate].

A 78-year-old woman was diagnosed with a gastrointestinal stromal tumor(GIST)of the stomach, gradually increasing from 5 years prior. The tumor was suspected to invade the pancreatic body tail and spleen, as observed with computed tomography. Because the patient refused to undergo resection, we administered imatinib mesylate for 6 years.

[A Case Report of Appendiceal Cancer Complicated Appendicitis Treated with Single-Incision Laparoscopic Ileocecal Resection].

We report a case of appendicitis with an abscess that was treated with single-incision laparoscopic ileocecal resection with D2 lymphadenectomy because of intraoperative suspicion of appendiceal cancer. A 73-year-old woman was admitted to the hospital because of right lower abdominal pain. She was diagnosed with appendicitis with an abscess.

[Metachronous Bilateral Hemothorax Due to Reverse Chance Type Thoracic Fracture].

Metachronous bilateral hemothorax due to reverse Chance type thoracic fracture is very rare. In this case, we experienced a case of metachronous bilateral hemothorax, triggered by a thoracic fracture in which the anterior component of the spine collapsed, so-called reverse Chance type thoracic fracture. An 83-year-old woman with spinal kyphosis traumatically injured thoracic spine burst fracture, and bone fragments appeared on both sides of the destroyed vertebra.

[A Case of Small Bowel Adenocarcinoma That Was Diagnosed and Treated using Laparoscopic Surgery].

A 40-year-old man presented to our department with chief complaints of nausea and abdominal pain, and was diagnosed with small intestine ileus. After hospitalization, he underwent intestinal tract decompression using an ileus tube. A small bowel tumor was suspected as the cause of the intestinal obstruction.

[A Case of Rectal Villous Tumor Detected with Heart Failure and Electrolyte Imbalance].

A 74-year-old woman presented to our emergency department with a chief complaint of appetite loss, and already diagnosed dehydration and heart failure. After hospitalization, the signs of heart failure were improved with liquid supplementation and electrolyte revision. At admission, computed tomography incidentally detected a rectal tumor.

Ultrathin Bronchoscopy with Multimodal Devices for Peripheral Pulmonary Lesions. A Randomized Trial.

Rationale: The combination of an ultrathin bronchoscope, navigational technology, and endobronchial ultrasound (EBUS) seems to combine the best of mutual abilities for evaluating peripheral pulmonary lesions, but ultrathin bronchoscopes that allow the use of EBUS have not been developed so far.

Objectives: To compare the diagnostic yield of transbronchial biopsy under EBUS, fluoroscopy, and virtual bronchoscopic navigation guidance using a novel ultrathin bronchoscope with that using a thin bronchoscope with a guide sheath for peripheral pulmonary lesions.

Methods: In four centers, patients with suspected peripheral pulmonary lesions less than or equal to 30 mm in the longest diameter were included and randomized to undergo transbronchial biopsy with EBUS, fluoroscopy, and virtual bronchoscopic navigation guidance using a 3.

Primary pulmonary mucinous (colloid) adenocarcinoma with postoperative bone metastasis.

We describe rare primary pulmonary mucinous (colloid) adenocarcinoma in an 80-year-old man. Chest computed tomography revealed a lobulated, well-defined nodule with a diameter of 3.2 cm in the right middle lobe.

The usefulness of endobronchial ultrasonography-guided transbronchial needle aspiration at the lobar, segmental, or subsegmental bronchus smaller than a convex-type bronchoscope.

Background: Endobronchial ultrasonography-guided transbronchial needle aspiration (EBUS-TBNA) is a standard procedure for approaching the lesion adjacent to extrapulmonary bronchus. We started to use wedge insertion of a convex endobronchial ultrasound bronchoscope into bronchi narrower than the diameter of the bronchoscope itself to perform EBUS-TBNA. Our objective was to investigate the bronchus in which EBUS-TBNA was possible and safe.

[Two cases of retroperitoneal liposarcoma].

We report 2 cases of retroperitoneal liposarcoma. Case 1: A 53-year-old woman with severe abdominal distension and dyspnea was admitted to our hospital. Abdominal computed tomography(CT) and magnetic resonance imaging(MRI) revealed a large mass that occupied almost the entire abdominal cavity.

[A case of acute mediastinitis after endobronchial needle aspiration].

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become widespread, but reports of complications are rare.

Case: An enlarged mediastinal lymph node (4R) was detected in a 67-year-old man 33 months after surgery for rectal cancer, and we performed EBUS-TBNA to confirm the diagnosis. He was then admitted to hospital 13 days after the procedure, with cough, a swollen mediastinal fatty area around the 4R lymph node, and elevated WBC and CRP levels.

Female gender is an independent prognostic factor in non-small-cell lung cancer: a meta-analysis.

Purpose: It is not clear whether women with non-small-cell lung cancer (NSCLC) live significantly longer than men. Thus, we conducted a meta-analysis of published studies to quantitatively compare NSCLC survival data between genders.

Materials And Methods: A MEDLINE Web search for computer-archived bibliographic data regarding overall survival differences between genders was performed.

Comparison of 21-gauge and 22-gauge Needles for Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration of Mediastinal and Hilar Lymph Nodes.

Background: : Although endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) using a 22-gauge needle has emerged as an accurate, minimally invasive, and safe technique for accessing undiagnosed mediastinal adenopathy, particularly in patients with lung cancer, the small sample size obtained by a conventional needle may limit the accuracy of the result.

Objectives: : We evaluated the safety and efficacy of obtaining specimens using 21-gauge needles, comparing diagnostic yield with conventional 22-gauge needles.

Methods: : Participants consisted of 56 consecutive patients with mediastinal lesions referred to our institution for diagnostic EBUS-TBNA.

Pleuroperitoneal shunt for chylothorax and chylopericardium in lung cancer: a case report.

A 70-year-old man with T1N3M1 stage IV squamous cell carcinoma in the right upper lobe of the lung developed chylothorax and chylopericardium as rare simultaneous complications. Intravenous hyperalimentation, repeated pleurodesis, and ligation of the thoracic duct were all ineffective. A pleuroperitoneal shunt was inserted into the right pleural cavity from the fifth intercostal space, and a peritoneal catheter was placed in the abdominal cavity.

[Pulmonary alveolar proteinosis detected by a nodular lesion on chest computed tomography].

A 74-year-old woman was admitted to our hospital for further examination of chest X-ray abnormality. The chest computed tomography (CT) revealed a nodular lesion (1.0 cm in diameter) in right lung.

Mesenteric paraganglioma: report of a case.

We report a rare case of a solitary primary paraganglioma arising in the mesentery, found in a 72-year-old woman who presented with abdominal pain and a palpable abdominal mass. This extra-abdominal paraganglioma developed from paraganglionic cells that travelled by vertebral migration from the root of the superior mesenteric artery. Extra-adrenal paraganglia extend anywhere from the neck down to the base of the pelvis.

Effects of moderate hypothermia on proinflammatory cytokine production in a rat model of caerulein-induced pancreatitis.

Introduction: Proinflammatory cytokines act as mediators of the local and systemic manifestations of acute pancreatitis (AP).

Aims: To investigate whether moderate hypothermia (MH) (32 degrees C) can reduce the severity of AP by inhibiting cytokine production in a rat model of caerulein-induced pancreatitis.

Methodology: Rats were divided into three groups: control rats (Group I), AP rats treated with normothermia (38 degrees C) (Group II), and AP rats treated with MH (Group III).
