Seroma

This is a prospective, open-label, non-randomized interventional feasibility study with a nested qualitative analysis. The study exploratively verifies the feasibility of targeted prophylactic closed incision negative pressure wound therapy (ciNPWT) in clinical practice for patients with a high predicted risk of wound healing complications and compares the 30-day incidence of postoperative complications with standard dressing. Participants will: * Get ciNPWT or standard dressing after planned laparotomy * Answer the questionairs about qualite of life * Will visit the clinic 30 days after surgery to see the final result

Seromas are collections of serous fluid that can develop following surgical procedures and may persist as fibrous-lined pseudocysts if not adequately treated. In orthopedic surgery, particularly after arthroplasty, seromas can impair wound healing, increase pain, and limit postoperative rehabilitation, potentially compromising patient recovery. Current treatment strategies including compression, percutaneous aspiration, and repeat surgical intervention have variable success, and aspiration carries the risk of introducing bacteria into an otherwise sterile fluid collection. Sclerotherapy has been proposed as an alternative strategy to induce fibrosis within the cavity and eliminate the potential space. Doxycycline, a tetracycline antibiotic commonly used for pleurodesis, has demonstrated sclerosing properties through mechanisms including mesothelial cell destruction, inhibition of fibrinolysis, and stimulation of fibroblast activity. While doxycycline sclerotherapy has shown success in treating conditions such as Morel-Lavallée lesions and has been described in isolated orthopedic case reports, its role in managing postoperative seromas after arthroplasty remains poorly studied. Further investigation is needed to determine whether doxycycline injection may serve as a safe and effective treatment to reduce persistent seromas and the need for additional interventions in orthopedic patients.

The aim of this study is to evaluate the clinical presentation and management strategies of seroma formation following posterior lumbar spine decompression.

The goal of this clinical trial is to compare the outcomes of High-volume saline irrigation vs Povidone-iodine solution cleaning of the intraoperative incision wound in preventing superficial surgical site infections in patients undergoing emergency laparotomies. The main question it aims to answer are: * Incidence of SSI after intervention * Length of hospital stay Participants will be randomly assigned to two groups receiving either of the two groups: Group A: 1000ml of IOWI with saline solution prior to incision closure Group B: The incisional wound will be closed conventionally without irrigation. Researchers will compare groups A( experimental group) and B (control group) to compare the incidence of superficial surgical site infections after intervention.

The study is designed as international, prospective, minimal interventional study in cooperation with EUBREAST e.V. (European Breast Cancer Research Association of Surgical Trialists). Furthermore, it is planned to initiate a registry for postoperative breast seromas.

Rationale: Flap fixation significantly reduces the incidence of seroma formation after mastectomy. Therefore, research should focus on finding the most optimal way to secure the skin flaps to the pectoral muscle. Previous studies have compared running sutures, interrupted sutures and tissue glue application to conventional wound closure. A recent systematic review with network meta-analysis indicated running sutures as the most optimal technique, however direct comparisons and high quality articles were lacking. Objective: This prospective trial aims to directly compare running sutures with interrupted sutures in order to prevent complications in patients undergoing a mastectomy. Study design: This trial will combine a retrospective cohort from the previous SARA-trial in Zuyderland MC with a randomised prospective trial. This study design was chosen to acquire a sample size with sufficient power and the ability to conduct this study in an acceptable time frame. Study population: A retrospective cohort of patients participating in the SARA trial (RCT) and a prospective cohort of patients undergoing a mastectomy for breast cancer. Intervention: Group 1: Flap fixation after mastectomy with running sutures. Group 2: Flap fixation after mastectomy with interrupted sutures. Main study parameters/endpoints: The primary endpoint is the incidence of complications requiring interventions in both groups, including clinically significant seroma, infections and bleeding complications. Secondarily, the length of the procedure and cosmetic results will be compared. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: When participating, patients will undergo 3 additional outpatient clinic visits. Study visits will be combined with regular visits where possible, including the first postoperative visit after 7-10 days and either the 6 week or 3 month visit.
