Introduction: This study aimed to evaluate the short- and long-term outcomes of single-incision laparoscopic colectomy (SILC) for right-sided colon cancer (CC) using a craniocaudal approach.

Patients And Methods: The data of patients who underwent SILC for right-sided CC at our hospital between January 2013 and December 2022 were retrospectively collected. Surgery was performed using a craniocaudal approach.

Relationship between laparoscopic total gastrectomy-associated postoperative complications and gastric cancer prognosis.

This study aimed to investigate the incidence and prognosis of postoperative complications after laparoscopic total gastrectomy (LTG) for gastric cancer (GC). We retrospectively enrolled 411 patients who underwent curative LTG for GC at seven institutions between January 2004 and December 2018. The patients were divided into two groups, complication group (CG) and non-complication group (non-CG), depending on the presence of serious postoperative complications (Clavien-Dindo grade III [≥ CD IIIa] or higher complications).

Inguinal single-port approach of endoscopic component separation for abdominal wall defects: A case series.

Background: The component separation (CS) technique is widely used for abdominal wall defects, particularly in infected wounds. CS is associated with many wound complications due to subcutaneous blood flow disturbance. Endoscopic component separation (ECS) has fewer wound complications compared to CS and has been performed recently.

Transanal total mesorectal excision after incomplete endoscopic submucosal dissection for early-stage low rectal cancer: A small case series.

Endoscopic submucosal dissection (ESD) for colorectal cancer is challenging but is gradually being performed worldwide. It is less invasive than surgical resection and can be performed on lesions in which malignancy cannot be diagnosed. In low rectal cancers, changes such as scarring after ESD may make it challenging to preserve the anus when additional surgical resection is required.

Outcomes of laparoscopic total gastrectomy in elderly patients: a propensity score matching analysis.

Purpose: This study evaluated the short-term outcomes and prognosis after laparoscopic total gastrectomy (LTG) in elderly patients aged ≥ 80 years in a multicenter retrospective cohort study using propensity score matching.

Methods: We retrospectively enrolled 440 patients who underwent curative LTG for gastric cancer at six institutions between January 2004 and December 2018. Patients were categorized into an elderly patient group (EG; age ≥ 80 years) and non-elderly patient group (non-EG; age < 80 years).

Comparison of clinicopathological features and long-term prognosis between mixed predominantly differentiated-type and pure differentiated-type early gastric cancer.

Background: Recent studies have shown that mixed predominantly differentiated-type (MD) early gastric cancer (EGC) might have more malignant potential than pure differentiated-type (PD) EGC. However, no study has analyzed all differentiated-type EGC cases treated endoscopically and surgically. This study aimed to compare the differences in clinicopathological features and long-term prognosis between MD- and PD-EGC.

The effect of the body mass index on the short-term surgical outcomes of laparoscopic total gastrectomy: A propensity score-matched study.

Purpose: This study aimed to evaluate the relationship between the body mass index (BMI) and the short-term outcomes of laparoscopic total gastrectomy (LTG).

Subjects And Methods: Data of patients who underwent LTG for gastric cancer at six institutions between 2004 and 2018 were retrospectively collected. The patients were classified into three groups: low BMI (<18.

Resection of mediastinal goiter extending to the carina with use of artificial pneumothorax, two-lung ventilation, and thoracoscopy, with the patient in a prone position.

A 67-year-old woman was presented with a mediastinal tumor extending from the left lobe of the thyroid and passing through the posterior trachea, causing displacement of the esophagus to the left side of the patient and then descending into the right side of the mediastinum to below the carina. Surgery was performed under two-lung ventilation with the patient in a prone position; general anesthesia was performed with a single-lumen tube combined with artificial pneumothorax. In thoracoscopic surgery, we were able to confirm and preserve anatomical structures.

Atypical presentation of a cushion sign-positive stomach gastrointestinal stromal tumor with cystic formation: A case report.

Gastrointestinal stromal tumors (GIST) typically appear as solid masses, and cystic formation is uncommon. Most stomach GISTs with cystic formation progress outside the gastric wall and are frequently misdiagnosed as epigastric cystic tumors derived from pancreas or liver. An asymptomatic 72-year-old male underwent esophagogastroduodenoscopy, which revealed a submucosal tumor (SMT), approximately 50 mm in diameter, at the anterior wall of the gastric angle.

Circular versus linear stapling in esophagojejunostomy after laparoscopic total gastrectomy for gastric cancer: a propensity score-matched study.

Purpose: We used propensity score matching to compare the complication rates after laparoscopic total gastrectomy (LTG) with esophagojejunostomy (EJS) performed using a circular or a linear stapler.

Methods: We retrospectively enrolled all patients who underwent curative LTG between November 2004 and March 2016. Patients were categorized into the circular and linear groups according to the stapler type used for the subsequent EJS.

Immunoglobulin G4-related disease presenting as a pulmonary nodule with an irregular margin.

We report a case of immunoglobulin G4 (IgG4)-related lung disease presenting as a solitary pulmonary nodule with an irregular margin on computed tomography. The nodule showed a high standardized uptake value on positron emission tomography. A malignant pulmonary tumour could not be excluded.

Risk factors and management for gastric stenosis after endoscopic submucosal dissection for gastric epithelial neoplasm.

Background: Only a few studies have reported treatment options for stenosis after endoscopic submucosal dissection (ESD) for gastric neoplasms. This study aimed to identify the risk factors for and evaluate the management of stenosis after ESD for gastric epithelial neoplasms in the cardia and antrum.

Methods: We retrospectively reviewed 1218 patients (1447 gastric epithelial neoplasms) who underwent ESD at Tonan Hospital from June 2004 to November 2015.

Short- and long-term outcomes of endoscopic submucosal dissection for early gastric cancer in elderly patients aged 75 years and older.

Background: Only a few studies have reported long-term outcomes for endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) in elderly patients. The aim of this study was to evaluate the efficacy of ESD for EGC in elderly patients ≥75 years with respect to both short- and long-term outcomes.

Methods: We reviewed the clinical data of elderly patients ≥75 years who had undergone ESD for EGC at Tonan Hospital from January 2003 to May 2010.

[Surgical Treatment for Refractory Metastatic Lung Tumors from Urachal Carcinoma after Chemotherapy].

[A case of stomal variceal hemorrhage successfully treated using sclerotherapy].

A 72-year-old man underwent transverse colostomy for sigmoid colon cancer with multiple liver metastases. Subsequent chemotherapy effectively reduced liver metastases, and sigmoidectomy was performed. However, the liver metastases recurred and the patient developed stomal varices due to portal hypertension.

Totally laparoscopic gastrectomy for gastric cancer after endoscopic submucosal dissection: a propensity score matching analysis.

Purpose: A recently developed endoscopic mucosal resection (EMR) procedure, endoscopic submucosal dissection (ESD), makes en bloc resection possible for mucosal cancer regardless of lesion size. ESD involves deeper and wider dissection of the gastric wall and may therefore increase the difficulty of subsequent totally laparoscopic gastrectomy (TLG) and the risk of complications. However, the influence of ESD on subsequent TLG has yet to be demonstrated.

[A Well-differentiated Mediastinal Liposarcoma that Expanded into the Right Thoracic Cavity with Dedifferentiation].

A 77-year-old man was referred to our hospital because of massive opacification of the right hemithorax on chest radiography. Chest computed tomography (CT) revealed a 25×18-cm heterogeneous tumor in the right hemi-thorax. Chest CT scan obtained 6 years before the referral showed an 8×2-cm homogeneous lipomatous mass in the anterior mediastinum suggesting a well-differentiated liposarcoma.

[Successful Treatment of a Giant Emphysematous Bulla with Intracavity Drainage and Bronchial Occlusion in a Patient Receiving Home Oxygen Therapy].

A 74-year-old man was brought to our hospital for an acute exacerbation of respiratory failure. He had severe progressive dyspnea for a few days and had received home oxygen therapy for 4 years. Chest radiography revealed a giant bulla occupying the entire right hemithorax with a remarkable shift of the mediastinum to the left.

Efficacy and safety of artificial pneumothorax under two-lung ventilation in thoracoscopic esophagectomy for esophageal cancer in the prone position.

Background: Thoracoscopic esophagectomy for esophageal cancer performed using two-lung ventilation in the prone position has many advantages, such as convenient anesthesia induction and maintenance, and good oxygenation. We examined the safety of surgery and anesthetic management by following chronological changes in intraoperative respiration and hemodynamics.

Methods: We focused on the most recent and consecutive 14 cases of thoracoscopic esophagectomy for esophageal cancer in the prone position performed from November 2010 until recently.

[Diaphragmatic eventration with shock and respiratory distress requiring emergency plication; report of a case].

A 80-year-old female with an eventration of the left diaphragm, which had been noticed with routine chest roentgenogram in 2006, presented with severe dyspnea and shock vital in 2012. The chest X-ray on admission disclosed elevation of the left hemidiaphragm, dislocation of the heart to the right. The diagnosis of eventration of the diaphragm was confirmed with a computed tomographic scan.
