Surgical Incision

The goal of this clinical trial is to investigate Negative Pressure Wound Therapy (NPWT) in adults undergoing emergency laparotomy. The main question it aims to answer is: Does NPWT decrease wound complications? Researchers will compare it against regular dressings to see if NPWT is superior.

Patients undergoing routine surgery in the Department of Dermatology for any indication on non-scalp skin and closed in linear fashion with scar greater than or equal to 4.5cm in length will be invited to participate in this split scar, head to head study comparing zinc oxide and petrolatum. Patients will apply respective ointments to each half of scar daily for one month and maintain a log of these activities. They will be seen at 1 week, 4 weeks, 8 weeks, and 6 months post-operatively for photographic scar assessment and to complete the patient portion of the Patient and Observer Scar Assessment Scale (POSAS), a quantitative objective assessment of scar appearance. Trained observers (board-certified dermatologists) will score the observer portion of the scale. POSAS outcomes, post-operative infections, linear density of epidermal seal will be assessed at the 1 week, 4 weeks, 8 weeks, and 6 months post-operative periods and compared between the two groups. Participants will have parking validated for all visits and upon completion of all portions of the study will receive a standardized skin care gift bag containing samples for hypoallergenic skin care products (washes, moisturizers, etc.).

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 main objective of this clinical trial is to demonstrate the safety and efficacy of REBUILD when used to support abdominal wall closure after laparotomy. The main question it aims to answer are whether the device when used to support suture in abdominal wall closure safely maintains apposition of the abdominis rectus muscles within a pre-defined distance. Participants will undergo standard of care laparotomy and the investigational device will be used to support the suture used to close the abdominal wall. Participants will have an MRI at 1-month after surgery to measure the distance between the abdominus rectus muscles.
