Filter by:This is a prospective, single-center, open-label, non-randomized controlled real-world study aimed at exploring a novel approach to cavity construction for thyroid endoscopic surgery. The study seeks to evaluate its effectiveness and safety while accumulating further evidence-based medical data. Three hundred patients with thyroid tumors were divided into an experimental group (150 cases receiving a new endoscopic thyroid surgery technique, namely, dual-port trans-subclavian thyroid endoscopic surgery) and a control group (150 cases undergoing traditional open thyroid surgery) according to their treatment intention. Laboratory and medical data from specified follow-up points are collected, and adverse events are recorded detailly. The primary efficacy endpoint is a comparison of surgical complications between the two treatment groups. Secondary endpoints include: (1) levels of IL-2, IL-4, IL-6, IL-10, TNF-α, INF-γ, renin, angiotensin II, and aldosterone preoperatively and on the second day postoperatively; (2) NRS scores on the first day postoperatively; (3) length of hospital stay, duration of surgery, total treatment cost, and postoperative drainage volume; and (4) assessment of wound satisfaction during a three-month follow-up visit. Safety assessments include adverse events, vital signs, and pathological examinations.
What the investigatorpropose in this protocol is a technique already used in clinical practice. It prevents the risk of bleeding and make third space endoscopy easier, quicker, safer and cheaper. Indeed, we noticed that preventive underwater coagulation of the candidate vessels during the submucosal dissection with the Hybrid Knife (HK), seal the wall of the vessel, resulting in a subsequent cut under CO2 without any bleeding. Such preventive coagulation is likely to be related with the conduction of the current underwater as it focalizes all the power on the interface between the vessel and the water, allowing a soft sealing of the vessel without cutting it. Despite widely used, there is no evidence up to know on the benefit and harm of such coagulation technique. The hypothesis is that the use of this approach in clinical practice, especially when used to coagulate a vessel, may lead to an increase in safety, feasibility and cost-effectiveness, reducing the procedural time, the rate of complications and the need for coagulation forceps in comparison with the conventional preventive coagulation technique under CO2 insufflation. Therefore, this randomized study compares the underwater coagulation technique with the conventional coagulation technique in the CO2 setting during the submucosal dissection in third space endoscopy.
The aim of the research has become to create a sphincterotome and a method that takes into account the anatomical structure of the sph Oddi. The disadvantages of pull-type sphincterotome led to develop a new sphincterotome. The characteristic features of new antegrade sphincterotome are: it is inserted ready to use; the direction of cutting is strictly determined; fully controlled depth of the cut. Thanks to shaping as it hook the sphincterotome has been extracted cutting the circular layer only. The cutting wire is located between two teflon catheters preventing the longitudinal muscle layer from being damaged. The distance between the catheters determines the depth of the cut. Endoscopic transpapillary antegrade sphincterotomy developed by Dr. Dovbenko -(ASD) performance in such case allowed: to manage the papillary stenosis; to treat complicated form of gallstone disease; In research group this method allowed to avoid cholecystectomy in 71,2 % of cases
The aim of this study is to determine the impact of endoscopic transsphenoidal pituitary surgery on nasal function using a numerical simulation and to compare the difference between two kinds of transsphenoidal approachese(single nostril approach and bilateral nostril approach)．
Objective to compare the advantages and disadvantages of robotic and conventional endoscopic thyroidectomy for thyroid cancer.
Nasopharyngeal carcinoma (NPC) is most prevalent in eastern Asia, with the highest incidence reported among the Cantonese population from the province of Guangdong. Radiotherapy is the cornerstone of initial treatment due to the radiosensitive behavior of NPC and its deep-seated location. Although radiotherapy has achieved satisfactory results, it can also cause some severe adverse events. Currently, surgery is only applied to the treatment of recurrent NPC (rNPC) patients, mainly dominated by the conventional open surgery. However, the traditional surgery was accompanied by high rate of treatment-induced complications and low rate of block removal, which greatly limited the surgical application to the treatment of primary NPC. With the continuous improvement in surgical techniques, especially the electronic endoscopic system to be used in the surgical treatment recently, endoscopic nasopharyngectomy can largely overcome these shortcomings of traditional surgery mentioned above. In addition, the investigators retrospectively analyzed the survival outcomes of 9 patients with NPC (all T1N0M0 according to the UICC / AJCC seventh staging) treated with endoscopic nasopharyngectomy in our hospital, with 5-year rate of overall survival, loco-regional-free survival, distant metastasis-free survival of 100%. Therefore, the investigators considered endoscopic nasopharyngectomy for staged I NPC patients feasible. This study will focus on the survival outcomes and quality of life of the staged I NPC patients treated with endoscopic nasopharyngectomy.
