Background: The purpose of this study was to examine the feasibility of performing totally endoscopic myocardial revascularization through the abdominal cavity.
Methods And Results: The right gastroepiploic artery was harvested endoscopically through three troacars in 46 human cadavers. Then, a 5-cm hole was made in the diaphragm to expose the right coronary artery. With the help of two vacuum pods, we fixed a site of the right coronary artery and made a right gastroepiploic artery-right coronary artery anastomosis. In 20 cases, continuous Prolene suture was used, and in 26 experiments, we applied a sutureless technique. Twenty-three anastomosis were patent.
Conclusions: Despite the low patency rate, the transabdominal approach of totally endoscopic bypass grafting is promising and demands further investigation.

Usefulness of Artificial Pneumothorax during Totally Endoscopic Off-Pump Left Atrial Appendage Closure and Surgical Ablation.

Purpose: In totally endoscopic off-pump left atrial appendage (LAA) closure and surgical ablation, securing the operative field is sometimes difficult in some patients because of a narrow working space caused by an elevated diaphragm or ventricles. In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax.
Methods: We analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation.

Ventral hernias pose a prevalent challenge in abdominal wall surgery, with ongoing advancements in repair techniques designed to enhance patient outcomes. This study evaluates the efficacy, safety, and socio-economic impact of Totally Extraperitoneal Sublay Repair (TES) versus Laparoscopic Intraperitoneal Onlay Mesh Repair (IPOM) for small to medium-sized ventral hernias, with a particular focus on postoperative quality of life and patient satisfaction. A retrospective cohort study was conducted, encompassing 125 patients who underwent ventral hernia repair between May 2018 and November 2023.

To investigate the correlation between uterine volume and intrauterine adhesion (IUA). From June 2018 to November 2019, totally 7 007 patients who underwent hysteroscopy in outpatient operating rooms of Gynecological Minimally Invasive Center, Beijing Obstetrics and Gynecology Hospital were retrospectively analyzed Patients of reproductive age with IUA without uterine fibroids and adenomyosis were selected as IUA group, and patients of reproductive age without uterine fibroids and adenomyosis without IUA during the same period were selected as the control group. The propensity score matching (PSM) method was used to perform 1∶1 matching for the two groups of patients, matching variables included age, height, weight, body mass index (BMI), gravidity, parity, and number of abortion curettage.

: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy.

Background: Given the increasing prevalence of antiplatelet agent use and the lack of high-quality evidence, the CAPTAIN trial aimed to investigate the safety and provide recommendations on continuing acetylsalicylic acid perioperatively in patients undergoing elective laparoscopic totally extraperitoneal inguinal hernia repair (LIHR).
Methods: The CAPTAIN trial was a multicentre, surgeon blind, randomized controlled trial conducted from April 2016 to April 2023. Patients undergoing LIHR were eligible for inclusion.
