Filter by:Even after the wide introduction of chemo/radiotherapy in the treatment algorithm, adequate surgery remains the cornerstone of gastric cancer treatment with curative intent. A proper D2 lymphadenectomy is associated with improved cancer specific survival as confirmed in Western countries by fifteen-year follow-up results of Dutch and Italian randomized trials. In clinical practice, the total number of harvested lymph nodes is often considered as a surrogate marker for adequate D2 lymphadenectomy; nonetheless, the number of retrieved nodes does not necessarily correlate with residual nodes, which intuitively could represent a more reliable marker of surgical adequacy. The availability of an efficient tool for evaluating the absence of residual nodes in the operative field at the end of node dissection could better correlate with survival outcomes. The goal of this multicentric observational prospective study is to test the reliability of a new score (PhotoNodes Score) created to rate the quality of the lymphadenectomy performed during minimally invasive gastrectomy for gastric cancer. The score is assigned by assessing the absence of residual nodes at the end of node dissection on a set of laparoscopic/robotic high quality intraoperative images collected from each patient undergoing a minimally invasive gastrectomy with D2 node dissection. Ideally, this tool could be a new indicator of the quality of D2 dissection and could assume a prognostic role in the treatment of gastric cancer.
A total of 50 patients aged between 18-60 years, classified as American Society of Anesthesiologists (ASA) I-II, undergoing elective total laparoscopic hysterectomy in the steep trendelenburg position (STP) will be included in the study. Preoperatively, an ophthalmologist will perform an eye examination on the patients, and intraocular pressure will be measured using a non-contact computerized tonometer (Topcon CT-800, Japan). Central corneal thickness and iridocorneal angle will be measured using a topography device (Sirius Topography, CSO, Italy), and the thickness of the retinal nerve fiber layer (RNFL) will be measured using an optical coherence tomography (OCT) device (DRI OCT Triton, Topcon, Japan). Patients' demographic data and operation durations will be recorded. Intraocular pressure (IOP) will be measured in the supine position after intubation (T1), during pneumoperitoneum (T2), in the steep Trendelenburg position (23°, head down) (T3), at the end of the operation when pneumoperitoneum is terminated (T4), after returning to the supine position (T5), and 10 minutes after returning to the supine position (T6). Simultaneously with IOP measurements, the patients' hemodynamic data (Blood pressure, heart rate, end-tidal CO2, partial saturation) will be recorded.

Effectiveness of opioid free anesthesia using Dexmedetomidine to inhibit nociception in abdominal laparoscopic surgery
In order to improve the implementation of routine surgical video recording, the researchers want to understand what the challenges associated with the uptake of this technology are. The aim of this study is to explore the barriers faced by key stakeholders including the surgical care team, information governance, and patients within the field of surgical video reporting. The data from this qualitative study will allow the researchers to understand better the challenges associated with uptake of surgical video recording. This will allow the researchers to develop strategies to overcome these challenges and subsequently improve uptake of surgical video recording which will promote safer and more transparent surgery.
The purpose of this study is to assess the safety and ease of use of a trocar placement access device (TPAD) to assist with obtaining peritoneal access with a Veress needle, and for placing a primary trocar, during laparoscopic surgery.
This study aims to investigate the effect of varying insufflation pressures on post-operative pain and adequacy of surgical field visualization among patients undergoing laparoscopic surgery with a minimally invasive gynecologic surgeon.
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.
This study aims to investigate the effectiveness and safety of implementing a personalized positive end-expiratory pressure (PEEP) management strategy guided by esophageal pressure (Pes), as well as its potential to reduce the occurrence of postoperative pulmonary complications (PPCs) in elderly patients undergoing laparoscopic surgery.
