Laparoscopic Abdominal Surgery

This is a retrospective, multicenter cohort study to compare short- and long-term outcomes between robotic and laparoscopic hemicolectomy of right colon cancer.

This clinical trial aims to investigate the impact of multimodal analgesia regimens on postoperative pain management and gastrointestinal function recovery following laparoscopic abdominal surgery. The primary objectives are to determine: Which analgesic regimen is most effective in reducing postoperative pain? Which analgesic regimen is most effective in accelerating gastrointestinal function recovery? This study will compare epidural analgesia (EA), paravertebral block (PB), transversus abdominis plane block (TAP), and patient-controlled intravenous analgesia (PCIA) to identify the optimal method for pain control and the most beneficial for gastrointestinal recovery. Participants will receive one of the following treatments postoperatively: epidural analgesia, paravertebral block, TAP block, or patient-controlled intravenous analgesia. Rest pain (measured using the Numerical Rating Scale, NRS), dynamic pain (NRS), morphine equivalent consumption (mg), quality of sleep on the first night (Likert scale, 1-5), time to return of bowel function (h), time to recommence oral intake (h), time to first mobilization (h), quality of recovery (QoR, 0-15) on postoperative day 1, and length of hospital stay (days) will be recorded at 4, 8, 12, and 24 hours post-procedure.

Opioids analgesic are the gold standard for intraoperative pain management. Their short- and long-term adverse effect motivate anesthesiologists to explore opioid sparing strategies. Dexmedetomidine is a highly selective α2 adrenergic receptor agonist that could help minimize opioid consumption both intraoperative and postoperative due to its sedative, analgesic and sympatholytic properties. This new randomized controlled trial (RCT) will answer the question whether an intraoperative dexmedetomidine infusion compared to placebo has a clinically significant impact on intraoperative remifentanil consumption during a laparoscopic abdominal elective surgery.

The goal of this prospective, multicentric, observational, cohort study is to evaluate intraoperative adverse events (iAEs) through video-based assessment (VBA) across minimal invasive procedures performed in general surgery departments. The main questions it aims to answer are: * The prevalence, type, and severity of iAEs * Correlation between iAE and clinical outcomes * Correlation between iAE and surgical performance * Qualitative analysis of root cause analysis and mitigation strategies
