Background: Data regarding the safety and efficacy of delayed completion lobectomy (CL) following sublobar resections remain scant. We evaluated the technical difficulty and short-term outcomes of CL occurring at least 3 months following the anatomical segmentectomy or wedge resection.
Methods: Consecutive non-small cell lung cancer (NSCLC) patients who underwent a second resection within the same lobe at least 3 months after their initial resection from January 2013 to December 2019 at the Shanghai Pulmonary Hospital were retrospectively included. The patients were divided into a segmentectomy group (SG group) and a wedge resection group (WR group) based on their initial resection strategy. Baseline characteristics and short-term outcomes after CL between the two groups were compared.
Results: Twenty-five patients undergoing CL were included, nine in the SG group and 16 in the WR group. No deaths occurred within 30 days postoperatively, and the rate of overall postoperative complications was 28.0% (7/25). Statistically significant differences were found in rates of postoperative complications between the two groups (SG: 55.6% WR: 12.5%, P=0.03) and in the use of bronchoplasty or angioplasty during the CL (SG: 33.3% WR: 0.0%, P=0.04). After CL, no significant differences were found in 5-year recurrence-free survival (RFS) (WR: 66.7% SG: 61.0%, P=0.31) or overall survival (OS) (WR: 93.8% SG: 66.7%, P=0.06) between two groups.
Conclusions: Delayed CL occurring over 3 months after sublobar resection is a safe and effective procedure, with no deaths occurring within 30 days postoperatively. As compared to a segmentectomy at the time of the index operation, a wedge resection may portend less morbidity, with a decreased risk of needing adjunctive bronchoplasty or angioplasty procedures during CL. After CL, 5-year RFS and OS were comparable between WR and SG groups.

Background: Lung cancer is the first cause of cancer-related death. Awake lung resection is a new frontier of the concept of minimally invasive surgery. Our purpose is to demonstrate the feasibility of this technique for lobar and sublobar lung resection in NSCLC patients.

Objectives: This study aims to evaluate the ability of a periodontal resective procedure (the Proximal Wedge Technique) to improve the long-term health of the mandibular canines by reducing probing depths immediately post-surgery via targeted tissue recontouring and precise debridement. The technique aims to enhance periodontal health and stabilize the supporting structures of strategically important adjacent canine teeth, including alveolar bone, rather than relying solely on mandibular incisor extractions with simple closure.
Materials And Methods: A retrospective records review compiled data from patients with suprabony pockets of 6 mm or greater at the mesial aspect of the mandibular canines treated with the proximal wedge technique (PWT).

Involutional lower eyelid ectropion is a common disorder of the elderly population. Several surgical approaches have been described in the literature to address the multifactorial nature of this condition, each targeting different factors contributing to its development. Nevertheless, no single procedure has proven to be superior to the others.

With the publication of CALGB 140503, an increase in wedge resections for small, peripheral non-small cell lung cancer is expected; however, a relative paucity of data exists as to what defines a high quality oncologic wedge resection. The Thoracic Surgery Outcomes Research Network (ThORN), through expert discussion, guided by review of what limited data does exist, and through use of a modified Delphi process, provides these consensus statements defining an oncologically sound, high quality wedge resection. The statements are classified into five categories: 1) Preoperative Considerations 2) Technical Aspects 3) Lymph Node Assessment 4) Margin Assessment and 5) Tissue Handling by Pathology.

Ex vivo lung perfusion (EVLP) is used to evaluate donor lungs prior to lung transplantation. Development of pulmonary edema during EVLP is generally thought to represent inflammatory breakdown of the air-fluid barrier and these lungs are declined for transplant. We present the case of a donor lung that underwent stapled wedge resection during cold storage for air leak and the subsequent development of profound (∼650 mL) pulmonary edema around the staple line during EVLP.
