NCT03327922
This study aims to investigate whether the spacing of the interrupted deep (subdermal) sutures affects surgical wound cosmesis on the trunk and extremities. In other words, the investigator would like to determine which of the following yields a more cosmetically appealing scar: many closely approximated subdermal sutures or fewer, more widely spaced subdermal sutures. The investigator wishes to compare the effects of one versus two centimeter spacing between sutures.
NCT07451990
This randomized controlled trial compared two commonly used suture materials, Prolene and Vicryl, for closing the midline rectus sheath after elective laparotomy. Proper closure of the abdominal wall is important to reduce complications such as wound dehiscence and surgical site infection. Adult patients undergoing elective midline laparotomy were randomly assigned to rectus sheath closure using either Prolene or Vicryl sutures. All patients received the same standardized surgical technique and postoperative care. Participants were followed for 30 days after surgery to assess wound healing, wound dehiscence, surgical site infection, and length of hospital stay. The study aimed to determine which suture material is associated with fewer postoperative wound complications.
NCT07229222
The purpose of the study is to determine whether two-layered simple interrupted myometrial suturing is superior to double-layered continuous suturing for the prevention of uterine niche formation after primary cesarean section.
NCT03259945
The incidence of aortic valve disease is increasing steadily because of the ageing of the population. At a certain stage, replacement of the aortic valve improves symptoms and thus the quality of life of patients. Surgical aortic valve replacement is the " gold standard ". The procedure involves stopping the heart and setting up cardiopulmonary bypass (CPB) to ensure the oxygenation of tissues. The reference technique consists in suturing a prosthetic valve to the aortic annulus so as to restore normal function. This technique has very good results in the long term. The elective approach is sternotomy, which has certain drawbacks: post-operative pain, risk of infection, psychological trauma of a major incision. In recent years an alternative approach, right minithoracotomy, has been proposed. The drawback to this approach is that it increases aortic cross-clamp time and CPB time. More recently, new prosthetic valves, so-called "sutureless" or "rapid deployment" valves have become available. The main advantage of these valves is that they are easy to implant, as they do not require or need just a few sutures. As a result heart-arrest time is shorter, post-operative inflammatory syndrome is less frequent and transfusion needs are reduced. However, these valves have a metallic stent to fix the valve in place by pressing against the aortic annulus, which may give rise to intra-cardiac conduction disorders. Yet, very few studies have been conducted on this subject. The investigators wish to evaluate these conduction disorders in a cohort of patients operated on in this Department with this sutureless or rapid deployment valve technique.
NCT07274943
This study will compare two standard ways of stitching the kidney artery to the iliac artery in adults receiving a living donor kidney transplant. The two techniques are interrupted suturing and continuous suturing. The study will review past transplant cases and follow new patients at Assiut University Urology Hospital. For each patient, the team will record details of the operation, blood flow in the kidney artery, kidney function, and any surgical or vascular complications during the first three months after surgery. The main goals are to see whether one suturing pattern shortens cold ischemia time and improves early blood flow measurements, and to explore how these techniques affect early graft function, complication rates, and short-term graft and patient survival.
NCT07241507
The goal of this clinical trial is to learn whether the type of suturing technique used to close the abdomen after exploratory laparotomy affects the rate of wound complications. Specifically, the study aims to find out if using interrupted sutures results in fewer cases of wound dehiscence (wound reopening) compared to continuous sutures. The main question the study seeks to answer is: Does interrupted suturing reduce the frequency of wound dehiscence compared to continuous suturing in patients undergoing exploratory laparotomy? Researchers will also observe and compare wound infection rates between the two suturing methods. About 80 adult patients (18-60 years old) undergoing exploratory laparotomy at the Department of General Surgery, DHQ Teaching Hospital, Dera Ghazi Khan, will take part in this study. Participants will be randomly assigned to one of two groups: Group A: Continuous abdominal closure using No. 1 Vicryl suture Group B: Interrupted abdominal closure using No. 1 Vicryl suture All participants will have their baseline characteristics recorded, including age, gender, obesity, diabetes, and smoking status. The surgical technique and postoperative care will follow the hospital's standard protocols. After surgery, patients will be followed for four weeks with weekly clinical assessments to check for wound infection or wound dehiscence. The hypothesis is that patients whose abdominal wounds are closed with interrupted sutures will have a lower frequency of wound dehiscence compared to those with continuous sutures. The findings will help guide surgeons on which abdominal closure method provides better wound healing and fewer postoperative complications.
NCT07236853
The overall aim of this study was to evaluate the effects of hand-held suture exercises on non-locking continuous suture skills used in episiotomy repair in midwifery students. The study, conducted with a randomized, single-blind, controlled design, aimed to generate evidence of psychomotor skill transfer using Objective Structured Assessment of Technical Skills based performance scores and secondary indicators (time, number of errors, etc.).
NCT07127029
This study is designed to evaluate the effect of using petrolatum to coat gut suture. This coating is commonly performed to make the suture more easy to handle; however, it was unknown if it affects the absorption rate of the suture. Two gut sutures were placed into the skin of 14 healthy volunteers and randomized between coated and uncoated with petrolatum. Participants self-reported the time to resorption. The study concluded that there was no significant effect to the application of petrolatum, and reinforced that the gut sutures are a natural product with some inherent variability to their absorption.
NCT05895968
Through a single-center, exploratory clinical study, the safety and effectiveness of using barb wire in the incision and suture of posterior cervical surgery in obese patients were evaluated, providing a basis for its wide clinical application in posterior cervical surgery.
NCT04906824
This is a post-market, multi-centre, open-label registry designed to collect prospective safety and performance data on the use of VascuCel in patients who require great vessel reconstruction, peripheral vascular reconstruction or suture line buttressing. This registry will collect safety and performance data up to 2 years following implantation.
NCT05782010
The SCI-Pex study is a multicenter, prospective, non-controlled investigation on PexyEazy®, a new device for treatment of hemorrhoids based on the mucopexy method. Mucopexy is a well established method where sutures are applied above the hemorrhoids. When knots are tied, the hemorrhoids are lifted inwards to their normal position, which makes them swell down and symptoms disappears. PexyEazy® perform a mukopexy in a semiautomatic, faster and easier way on awake patient in less than 10 minutes. The SCI-Pex study will evaluate the safety and performance of PexyEazy on 35 patients with hemorrhoids grade II and III with a follow-up after 1 week, 3 months and 1 years. Adverse events, pain and other complications will be recorded, quality of life and hemorrhoid symptom questionnaires and clinical examination after 3 months and 1 year will be monitored to evaluate the result after a PexyEazy® procedure.
NCT06701786
This randomized controlled clinical trial aims to evaluate the additional effect on clinical outcomes of compressive sutures associated with coronally advanced flap (CAF) and subepithelial connective tissue graft (SCTG) for the treatment of RT1 gingival recessions (as classified by Cairo et al.). Forty patients presenting with at least one RT1 recession will be enrolled in the study. Twenty participants will undergo CAF + SCTG with compressive sutures while the other 20 participants will receive the same procedure without compressive sutures. The primary outcome, complete root coverage (CRC), will be assessed six months after treatment. Additional clinical parameters, including gingival recession (GR), clinical attachment level (CAL), pocket depth (PD), keratinized tissue width (KT), keratinized tissue thickness (GT), and Root Coverage Esthetic Score (RES), will be evaluated at baseline and at the six-month follow-up. Patient-reported outcomes (PROs) will also be measured, including the degree of general discomfort (D) experienced, assessed on a Visual Analog Scale (VAS) from 0 to 10, as well as patient-reported aesthetic satisfaction (PRES) and overall treatment satisfaction (OTS), both quantified on a VAS scale from 0 to 10.
NCT06638736
The study aims to compare outcomes in patient comfort, cosmetic appearance, and complication rates between sutures and staples in high tension areas for closures of skin cancers excised in a dermatology clinic.
NCT03650959
Evidence favours teaching procedural skills to medical students using a proficiency-based rather than time-based approach. Basic suturing skills can be taught through faculty-led, peer tutor-led, and computer augmented approaches. One method has yet to be identified as superior in terms of educational outcomes, resource utilization, and participant perspectives. Pre-clerkship medical students were randomized to: faculty, peer tutor, or computer augmented learning. Participants practiced suturing through their randomized method until they reached targeted proficiency defined using hand motion analysis (HMA). Proficiency was defined as a score of the average plus a standard deviation of five surgeons' HMA for two of three consecutive sutures using appropriate technique. The primary outcome was the number of stitches placed to achieve proficiency. The secondary outcomes were the number of sutures used, time, and costs incurred. Learning curves were constructed. Participants' perceptions were assessed using a follow-up survey.
NCT05796076
Background: In emergency departments, suturing is a common procedure but often causes anxiety and pain. Virtual reality (VR) intervention has been reported as a relaxing measure. Objective: The study aims to examine the effects of VR intervention on anxiety, pain, physiological parameters, local anaesthesia requirements and satisfaction in Chinese adult patients undergoing wound closure in emergency departments in Hong Kong Hypothesis:VR can alleviate anxiety and pain experienced by Chinese adult patients undergoing wound-closure procedures, the intervention can decrease extra local anesthesia requirements and physiological parameters during the procedures, and the intervention can significantly increase satisfaction during wound-closure procedures.
NCT06344962
Bronchial sleeve resection is performed as an alternative to pneumonectomy for lung cancer patients with centrally located lesions and limited cardiopulmonary reserve. Intraoperative bronchial anastomosis is very complex and difficult, mainly due to the difficulty of suturing and knotting in limited space. There are currently few studies comparing the clinical effects of absorbable and non-absorbable suture in bronchial sleeve resection. So the investigator wants to conduct a prospective study, trying to figure out this problem.
NCT06267599
This study aimed to evaluate the short-term and long-term complications of placenta percreta with bladder invasion. This evaluation focuses on cases where bladder dissection and ACAR-style bladder sutures were applied in cases of placenta percreta with bladder invasion that underwent uterine-sparing surgery or hysterectomy.
NCT04826653
Gingival recession is defined as the displacement of the soft tissue margin apical to the cemento-enamel junction with exposure of the root surface. It affects a broad population with presence of periodontal disease as well as periodontally healthy individuals. The occurrence of gingival recessions is age-dependent and their development begins relatively early in life. For instance, gingival recessions were noticed in more than 60% of Norwegian 20-year-olds and in more than 90% of the older population. Similar findings were reported in Brazilian and French population. In populations deprived of dental care, the occurrence of gingival recessions was even higher. Many factors have been implicated in the etiology of gingival recession, including plaque, position of the tooth in the arch and improper toothbrushing. It is difficult to see a single cause for the development of labial gingival recession. It has been demonstrated in several investigations that if left untreated, the probability of progression of the recession is high even with good oral hygiene. The indications for treatment of gingival recession are: esthetics, dental hypersensitivity, and the prevention of caries as well as further progression of the recession. Therapeutic options for recessions have been well documented with a high degree of success. Their ultimate goal is the location of the gingival margin coronal to the CEJ, with minimal probing depth and a pleasant soft tissue integration with the adjacent teeth. With such a prevalent condition, it becomes critical to discriminate when to treat these lesions and which are the anatomical and surgical characteristics that are going to determine the amount of root coverage. Regarding surgical characteristics, it has been demonstrated that the accomplishment of complete root coverage may be prejudiced by the post-surgical position of the gingival margin (the more coronal to the CEJ the greater the chance to achieve root coverage). The same author conducted a randomized clinical trial showing that the higher the flap tension, the lower the recession reduction. Another surgical factor affecting root coverage may be the use of microsurgical approaches by the use of smaller diameter sutures. According to a recently published systematic review, early suture removal (less than 10 days) can negatively affect root coverage outcome. The healing process after pedicle graft was investigated in an animal model study. The healing was divided into four different stages, the adaption stage (0-4 days), the proliferation stage (4-21 days), the attachment stage (27-28 days) and the maturation stage (1-6 months). During the proliferation stage, connective tissue invades the fibrin layer from the basal level of the flap, and after 6-10 days a layer of fibroblasts is seen in apposition to the root surface. These cells are believed to differentiate into cementoblasts at a later stage of healing. At the end of the proliferation stage, thin collagen fibers are formed adjacent to the root surface, but a fibrous union between the connective tissue and the root has not been observed. It seems logical that stabilizing the flap with sutures for a prolonged period of time during the proliferation phase would help maintain the gingival margin on a more coronal position postoperatively. On the other hand, the longer the sutures remain postoperatively, the greater the chances of plaque accumulation and inflammation affecting negatively to root coverage. The systematic review by Tatakis and Chambrone included 17 randomized clinical trials that provided an overall data of 325 single recession defects that were treated by coronally advanced flap. While they investigated time of suture removal, the studies included in this study did not account for this variable, thus leading to some bias. Moreover, different suture materials, type of suturing technique may also play an important role in the healing process. Therefore, the aim of this study is to evaluate the clinical outcome of timing suture removal regarding root coverage on coronally advanced flap.

Determine whether Mesh Suture achieves an acceptable safety and efficacy profile in load bearing internal tissue approximations. Mesh Suture has a novel design that permits tissue ingrowth and limits suture pull-through--items important for internal high-tension repairs
NCT04312165
The proposed project aims to evaluate the safety of DuraMesh™ suture for laparotomy closure in an emergent setting, while also providing preliminary efficacy data with regard to incisional hernia prevention. Conventional techniques for laparotomy closure in the setting of an emergency laparotomy or delayed abdominal closure suffer from a lack of durability, with incisional hernia rates of 30-34% reported. While prophylactic planar mesh placement has emerged as a cost-effective strategy to prevent hernia formation in the clean, elective laparotomy setting, higher rates of surgical site complications and increased technical complexity preclude its use in the emergency or contaminated setting. Utilized exactly like conventional suture without any change in surgical closure technique, DuraMesh™ provides the durability of planar mesh reinforcement without the marked increase in foreign material or added surgical complexity. As a result, DuraMesh™ is the only hernia prevention strategy that can be forward-deployed in support of the injured warfighter. While this study is specifically targeted to a gap in the care of the injured warfighter, the potential benefits extend well beyond the military applications. With over 2 million laparotomies performed annually in the United States, and approximately 20% of these resulting in an incisional hernia, the need for an alternative abdominal wall closure strategy is equally dire in the civilian setting. This clinical trial represents an opportunity to drive the needed paradigm shift towards prevention, rather than costly management of incisional hernias. The investigators anticipate this work will rapidly lead to further research, including providing the preliminary data necessary to launch a multi-center randomized controlled trial to assess the clinical efficacy of DuraMesh™ for hernia prevention in both the emergent and elective operative settings.
