NCT06688097
A total of 103 elective surgery patients who met the inclusion criteria were selected. After screening for eligibility according to the inclusion and exclusion criteria and signing informed consent, they were randomly divided into two groups. Upon entering the operating room, routine ECG monitoring was initiated, and a peripheral vein was opened. Ultrasound was used to measure the baseline cross-sectional area (CSA) of the gastric antrum in the supine position. After general anesthesia induction, positive pressure ventilation was applied via face mask. Group A received no external compression, while Group B underwent esophageal compression under ultrasound guidance.

Visceral pain following laparoscopic surgery is frequently underestimated, yet it is associated with a range of adverse outcomes. Effective visceral pain management should constitute an essential component of postoperative analgesic strategies following laparoscopic procedures. However, conventional analgesic agents, including μ-opioid receptor agonists, lack specificity for visceral pain. Anrikefon, a novel selective peripheral κ-opioid receptor agonist, demonstrates unique efficacy in alleviating visceral pain with a favorable safety profile. Preliminary studies showed that a single intravenous dose of anrikefon effectively alleviates postoperative pain after abdominal surgery with a low risk of adverse effects. The investigators hypothesize that an appropriate dosing regimen of anrikefon administered via patient-controlled intravenous analgesia (PCIA) pump, as part of a multimodal analgesic strategy, can specifically target and alleviate visceral pain after laparoscopic surgery, thereby achieving comprehensive postoperative analgesia.

Compared with traditional laparotomy, laparoscopic surgery offers advantages including minimal invasiveness, accelerated patient recovery, and reduced hospital stay. Although postoperative incision pain is generally less severe than that following laparotomy, it remains a notable clinical issue that impedes patient recovery. The majority of patients report incisional discomfort, with approximately 30% to 50% requiring oral analgesics to alleviate pain symptoms. Within the first two days after laparoscopic procedures, most patients experience varying degrees of incisional pain, with peak intensity typically occurring within hours after surgery and gradually subsiding over two to three days. Studies indicate that local infiltration anesthesia at the surgical site significantly ameliorates postoperative incision pain, enhances analgesic efficacy, and shortens recovery time in patients undergoing laparoscopic surgery.Liposomal bupivacaine(LB) is a novel, long-acting, sustained-release amide-type local anesthetic, providing localized analgesic effects for up to 72 hours. Some researchers have reported the analgesic effects of LB VS traditional local anesthetics infiltration, but the current research results are highly heterogeneous. More prospective studies are needed to evaluate whether LB infiltration is superior to the traditional local anesthetics for the management of postoperative pain. The investigators designed this study to compare the analgesic effect of using LB plus bupivacaine for local infiltration with bupivacaine along for patients after laparoscopic surgery.

Laparoscopic surgery, characterized by minimal invasiveness, rapid recovery, and shorter hospital stays, has been widely adopted in Gynecologic Oncology. However, the elevation and stretching of the diaphragm following pneumoperitoneum, combined with increased intra-abdominal pressure compressing visceral organs and causing ischemia-hypoxia, can trigger systemic inflammatory responses and lead to postoperLaparoscopic surgery, characterized by minimal invasiveness, rapid recovery, and shorter hospital stays, has been widely adopted in gynecological procedures. However, the elevation and stretching of the diaphragm following pneumoperitoneum, combined with increased intra-abdominal pressure compressing visceral organs and causing ischemia-hypoxia, can trigger systemic inflammatory responses and lead to postoperative pain. Inadequate or delayed pain management may prolong hospitalization, and some patients may develop chronic pain, resulting in altered behavioral patterns. As one of the analgesic strategies after abdominal surgery, transversus abdominis plane block (TAPB) not only reduces opioid consumption and the incidence of complications but also avoids adverse effects associated with epidural analgesia. Nevertheless, the analgesic duration provided by a single-injection TAPB is limited, while continuous TAPB faces constraints in clinical application due to challenges such as catheter fixation.Inadequate or delayed pain management may prolong hospitalization, and some patients may develop chronic pain, resulting in altered behavioral patterns.

NCT07427043
This prospective, interventional, open-label, phase 3 randomized study evaluates a multimodal analgesia discharge pathway to reduce automatic opioid prescribing following routine robotic-assisted laparoscopic prostatectomy (RALP). Patients are counseled on post-operative pain management and then may opt into or out of the study with randomization to discharge prescriptions including (A) multimodal plan with additional automatic opioid prescription or (B) multimodal plan alone and instruction to call phone line to request opioid prescription if pain management is insufficient. Additionally, a cohort of historical controls prior to implementation of the study is also prospectively assessed as a pre-study baseline. The primary outcome is postoperative opioid consumption. Secondary outcomes include bowel function recovery, unplanned care encounters including emergency department visits or postoperative phone calls, and same-day discharge rates.
NCT07414706
This randomized controlled trial evaluates whether perioperative intravenous lidocaine infusion, combined with port-site ropivacaine infiltration, improves postoperative recovery after laparoscopic abdominal surgery. Participants will be assigned 1:1 to receive either intravenous lidocaine during surgery plus ropivacaine infiltration at surgical closure, or ropivacaine infiltration alone. The primary endpoint is postoperative quality of recovery measured by the QoR-15 questionnaire. Secondary endpoints include postoperative pain and opioid consumption, as well as plasma lidocaine and ropivacaine concentrations to assess systemic exposure and safety.

The number of surgical procedures is increasing worldwide (1). Laparoscopic surgery is one of the surgical techniques that has become indispensable. Laparoscopic surgery is less invasive than laparotomy. Laparoscopic surgery is performed in several stages, one of which involves the creation of a peritoneal detachment. This detachment is achieved by the addition of a gas (CO2), which requires total relaxation of the abdominal muscle fibers. To achieve this, it is advisable to administer a muscle relaxant called curare (2). Curare-induced neuromuscular block, its depth and its release must be monitored during surgery. Curares act as acetylcholine antagonists, inducing neuromuscular block by competing with this neurotransmitter. In France, only one type of device, called an accelerometer, is used to monitor curarization. This device couples electrical stimulation of a nerve with an accelerometer. Curarization can be said to be deep, moderate, residual or absent. Despite curarization appearing deep to the accelerometer, operating conditions do not always seem ideal for abdominal contraction. Indeed, the muscles tested with this device do not concern the muscles involved in laparoscopic surgery. A currently unexploited surgical parameter, variation in insufflation pressure, could change our approach to intraoperative curarization.
NCT06602830
i-gel Plus is a novel supraglottic airway device (SGA). Feasibility of second-generation SGAs in patients undergoing elective laparoscopic surgery has been demonstrated in various studies. During laparoscopic surgery intrabdominal pressure is increased by capnoperitoneum and frequently minute ventilation has to be adopted to counteract hypercapnia, and higher inspiratory peak pressures have to be expected. It is uncertain, however, if the i-gel Plus facilitates appropriate ventilation with low leakage volumes in patients undergoing laparoscopic surgery. The primary aim of this single-center non-inferiority study is to assess the leak fraction of the i-gel Plus under conditions of capnoperitoneum (with and without Trendelenburg position) and to compare it with baseline conditions. Secondary aims are to assess secondary outcome parameters during capnoperitoneum (with and without Trendelenburg position) and to compare them with baseline conditions.

Hepatocellular Carcinoma(HCC) is a common disease in China, ranking as the fourth most prevalent malignant tumor and the third leading cause of cancer-related deaths in the country. Along with other liver, biliary, pancreatic, and splenic diseases, it poses a serious threat to the lives and health of the Chinese population. Precise organ resection techniques, centered around accurate preoperative imaging and functional assessment as well as meticulous surgical operations, have become the mainstream in hepatobiliary surgery in the 21st century. These techniques require precise dissection of intrahepatic blood vessels, the biliary system, and the pancreatic-splenic duct system to achieve an optimal balance between eradicating lesions and preserving the normal function of the organs while minimizing trauma to the body. Precise tissue resection via laparoscopy is a prerequisite for successful hepatobiliary surgery. Addressing how to assist surgeons in performing surgeries more safely and effectively, as well as how to enhance learning outcomes during training, are pressing issues that need to be resolved. Efficient learning and analysis of surgical videos may help improve surgeons' intraoperative performance. In recent years, advancements in artificial intelligence (AI) have led to a surge in the application of computer vision (CV) in medical image analysis, including surgical videos. Laparoscopic surgery generates a large amount of surgical video data, providing a new opportunity for the enhancement of laparoscopic surgical CV technology. AI-based CV technology can utilize these surgical video data to develop real-time automated decision support tools and surgical training systems, offering new directions for addressing the shortcomings of laparoscopic surgery. However, the application of deep learning models in surgical procedures still has some shortcomings. Based on this, the present study aims to conduct a retrospective analysis of cases involving laparoscopic hepatobiliary and pancreatic surgeries performed at Zhujiang Hospital, Southern Medical University, between 2017 and 2024. The goal is to investigate the recognition and validation of deep learning models for classifying surgical phase images in medical imaging, as well as for semantic segmentation of anatomical structures, surgical instruments, and surgical gestures, including abdominal CT and MRI.

The aim of this study is to evaluate and compare the surgical outcomes, including surgery duration, intraoperative blood loss, hospital stay, and postoperative complications (e.g., bile leakage and intestinal obstruction), between the two surgical approaches. The data collected from the patient records will be analyzed to identify factors influencing surgical outcomes and to guide future treatment decisions for CCC in pediatric patients.
NCT06447298
An increasing number of surgeries are being performed using laparoscopic techniques. This approach significantly reduces postoperative pain and speeds up recovery. Additionally, the resulting scars are smaller compared to open surgeries. This study evaluates the quality of care and communication satisfaction among parents of children undergoing laparoscopic surgery in the pediatric surgery department of Brest. The primary goal is to assess parental satisfaction with communication during the procedure. Parents of children who have undergone laparoscopic surgery will be invited to participate. Participants will complete a satisfaction questionnaire the day after surgery and participate in a follow-up phone interview 7 to 9 days post-surgery, incorporating the child's opinion if possible.
NCT06556498
there are currently two methods for fixation free laparoscopic inguinal hernia repair specifically based on the intrinsic properties of the device used. The Progrip mesh technique leaves the hernia orifice patent and relies on the established principle of strengthening the groin through scar tissue incorporation induced by foreign body reaction. In contrast, the ProFlor concept introduces a 3D dynamic regenerative scaffold that permanently obliterates the defect and regenerates the herniated inguinal barrier. This report presents the outcomes of laparoscopic techniques employing Progrip and ProFlor in randomized clinical trial. The results of this clinical study may have the potential to pave the way for innovative advancements in hernia repair techniques.
NCT06305975
This study aims to investigate the effect of two peritoneal entry techniques on intraoperative and post-operative outcomes among patients undergoing laparoscopic surgery with a minimally invasive gynecologic surgeon. Patients will be randomized to either blunt fascial or veress needle peritoneal entry. Insufflation times, failed entries, complications and post-operative pain scores will be collected. The investigators hypothesize that the blunt entry technique will be associated with shorter insufflation times and similar intraoperative and postoperative outcomes compared with the veress needle entry technique. Primary Objective: To evaluate the insufflation times and success upon peritoneal entry according to peritoneal entry technique. Secondary Objectives: To evaluate the surgical outcomes and patients pain scores according to peritoneal entry technique.

Effectiveness of opioid free anesthesia using Dexmedetomidine to inhibit nociception in abdominal laparoscopic surgery
NCT06376227
Brief Summary Background The preservation of the left colic artery (LCA) during rectal cancer resection remains a topic of controversy, and there is a notable absence of robust evidence regarding the outcomes associated with LCA preservation. And the advantages of robotic-assisted laparoscopy (RAL) surgery in rectal resection remain uncertain. The objective of this study was to assess the influence of LCA preservation surgery and RAL surgery on intraoperative and postoperative complications of rectal cancer resection. Methods Participants who underwent laparoscopic (LSC) or RAL with or without LCA preservation resection for rectal cancer between April 2020 and May 2023 were retrospectively assessed. The patients were categorized into two groups: low ligation (LL) which with preservation of LCA and high ligation (HL) which without preservation of LCA. A one-to-one propensity score-matched analysis was performed to decrease confounding. The primary outcome was operative findings, operative morbidity, and postoperative genitourinary function.
