Surgical outcomes and learning curve of complex versus simple segmentectomy for uniportal video-assisted thoracoscopic surgery: an initial experience of 100 cases of a single experienced surgeon.

Background: Complex segmentectomy for uniportal video-assisted thoracoscopic surgery (VATS) remains controversial due to procedural complexity and the risk of increased complications, unlike multiportal VATS. Demonstrating the perioperative results and proficiency of individual surgeon is believed to influence future dissemination for uniportal VATS. In this study, we aimed to compare the perioperative outcomes and learning curves of complex versus simple segmentectomy for uniportal VATS.

Predictive factors of early autologous blood pleurodesis for postoperative air leak.

Metachronous bilateral immunoglobulin G4-related pleuritis: A case report and literature review.

Immunoglobulin G4-related disease (IgG4-RD) is a newly recognized disease, and therefore its clinical features are not yet fully understood. Here, we describe a surgical case of metachronous bilateral IgG4-related pleuritis and postoperative chylothorax. This case could provide key insights into the pathology of IgG4-RD from a surgical perspective.

Treatment of severe micrognathia in an adult with distraction osteogenesis: A case report.

Key Clinical Message: Distraction osteogenesis (DO) of the mandible is often performed at a young age, and there are few reports after age 30, as in this case. The Hybrid MMF used in this case was useful in that it allowed correction of fine directionality.

Abstract: DO is often performed in young patients with a high capability of osteogenesis.

Experiences of novel cotton device for uniportal video-assisted thoracoscopic surgery: CS Two-Way Handle.

In Japan, cotton is commonly used in thoracic surgery for the gentle handling of organs as well as obtaining a good surgical field. While uniportal video-assisted thoracoscopic surgery is being recognized as a major surgical approach, use of cotton is not noted in this technique. Uniportal video-assisted thoracoscopic surgery needs curved instruments because they are effective in preventing the interference of instruments.

Preoperative umeclidinium/vilanterol or tiotropium improves postoperative FEV in lung cancer patients with comorbid untreated chronic obstructive pulmonary disease.

Background: This study aimed to examine the effects of preoperative interventions in lung cancer patients with untreated chronic obstructive pulmonary disease (COPD). We evaluated the efficiency of preoperative interventions using tiotropium (TIO) or umeclidinium/vilanterol (UMEC/VI).

Methods: We conducted a two-center retrospective study.

Acute hypercapnic respiratory failure in patients with obesity hypoventilation syndrome during the COVID-19 pandemic: Four case reports.

Obesity hypoventilation syndrome (OHS) can cause acute hypercapnic respiratory failure (AHRF). The onset of AHRF in four patients with OHS during the coronavirus disease 2019 (COVID-19) pandemic is reported in this study. Two men (23 and 45 years old) and two women (both 77 years old) presented to our hospital with AHRF.

A series of experiences with TissuePatch™ for alveolar air leak after pulmonary resection.

Objectives: Prolonged air leak after pulmonary resection strongly influences chest tube duration and hospitalization. This prospective study aimed to report a series of experiences with a synthetic sealant (TissuePatch™) and compare them with a combination covering method (polyglycolic acid sheet + fibrin glue) for air leaks after pulmonary surgery.

Methods: We included 51 patients (age: 20-89 years) who underwent lung resection.

[Dedifferentiated Liposarcoma Originated from Small Bowel Mesentery Resected under Laparoscopic Surgery-A Case Report].

A 74-year-old woman with severe anemia was presented to our hospital to investigate the cause of the disease. Under investigation, submucosal tumor in the small intestine was suspected. We performed the laparoscopic surgery for resection.

Lumbar Spinal Canal Stenosis in Acromegaly: A Case Report and Literature Review.

A 60-year-old Japanese man diagnosed with acromegaly at 28 years old had difficulty walking due to worsening back pain. He had been treated with somatostatin analog since 57 years old, but his pain and numbness continued to worsen. Lumbar magnetic resonance imaging showed disc bulging at L3/4 and L4/5, and he was diagnosed with lumbar spinal canal stenosis due to hypertrophy of the yellow ligament.

Decreased postoperative complications, neuropathic pain and epidural anesthesia-free effect of uniportal video-assisted thoracoscopic anatomical lung resection: a single-center initial experience of 100 cases.

Background: We aimed to analyze perioperative complications, postoperative neuropathic pain, and the necessity of epidural anesthesia in uniportal video-assisted thoracoscopic surgery (U-VATS) compared to conventional multiportal VATS (M-VATS) for anatomical lung resection.

Methods: This retrospective study included all patients who underwent elective VATS lobectomy and segmentectomy between April 2016 and December 2019. The exclusion criteria were as follows: age ≤19 years, planned thoracotomy, re-operation in thoracic surgery, median sternotomy, robot-assisted thoracic surgery, simultaneous resection of extrathoracic organs, locally invasive lung tumor with bronchoplasty or angioplasty, past or current neuropathic pain, and a large tumor with a minimum diameter ≥5 cm.

Actual incidence of severe neonatal hypoglycemia in non-risk term neonates: A 10 year survey of all cases in Toyama Prefecture, Japan.

Background: Severe neonatal hypoglycemia may cause irreversible neurological sequelae. Although blood glucose (BG) screening in term neonates without risk factors for hypoglycemia (non-risk neonates) is not recommended in the current guidelines, severe hypoglycemia can occur in such neonates. To evaluate the necessity of BG screening in non-risk neonates, it is important to determine the accurate incidence of severe hypoglycemia in those neonates.

Intraoperative methods for wrapping anastomoses after airway reconstruction: a case series.

Background: Anastomosis management is the main challenge of airway resection and reconstruction, and postoperative anastomotic complications, including ischemia, stenosis, dehiscence, and separation may lead to severe outcomes and a poor prognosis. The anastomotic buttress is vital in airway reconstruction, but the selection of surgical buttress and reinforcement remains controversial. We aimed to demonstrate and evaluate the buttress options of anastomosis, including their preoperative characteristics, the intraoperative process, and the incidence of postoperative complications to help address the controversy regarding anastomosis management.

Clinical Characteristics of Idiopathic Orbital Inflammation Syndrome in Relation to Intraocular Pressure.
