Plain English summary of protocol
Background and study aims
Postoperative abdominal wound dehiscence (PAWD) is also known as a burst abdomen. It can occur on average during the 7th day after surgery (postoperative) but may range between 1-23 days. An open abdomen or laparotomy wound is a general term for when the abdomen which is left intentionally open without any primary closure in critically ill patients where definitive repair is performed after a few weeks. Although there are a good number of studies on the effect of vacuum-assisted closure (VAC) therapy for open abdomen, very few studies have reported its usefulness in postoperative abdominal wound dehiscence. Therefore the aim of this study is to find out whether VAC therapy promotes healing in postoperative abdominal wound dehiscence.
Who can participate?
All patients aged over 18 who develop abdominal wound dehiscence in the postoperative period, excluding critically ill and ICU, bile leak patients
What does the study involve?
All patients are treated with VAC therapy and wound healing is assessed.
What are the possible benefits and risks of participating?
Possible benefits include improvement from local sepsis, early ambulation (walking), and early discharge from hospital. Possible risks include bleeding and pain.
Where is the study run from?
All India Institute of Medical Sciences Bhubaneswar (India)
When is the study starting and how long is it expected to run for?
May 2017 to December 2019

All India Institute of Medical Sciences Bhubaneswar (India)

| Scientific title | Assessing the effect of vacuum-assisted closure therapy in postoperative abdominal wound dehiscence: an observational study |
| Study objectives | Vacuum-assisted closure therapy (VAC) is a well-known technique used for the treatment of diabetic wounds, infected orthopaedic wounds, sternotomy wounds. Systematic reviews reported good facial closure rates with VAC therapy in open abdomen. Whereas very few studies reported its usefulness in postoperative abdominal wound dehiscence and most of them are retrospective studies. Therefore the researchers designed a prospective study on VAC therapy to know its effectiveness in PAWD. The aim of this study is to measure the effect of VAC therapy in terms of decreasing local sepsis, promoting granulation tissue and thereby achieving early cutaneous cover in postoperative abdominal wound dehiscence. |

| Health condition(s) or problem(s) studied | Postoperative abdominal wound dehiscence |
| Intervention | The data, including wound type, size for each patient are collected in a standardized manner. Then under sterile conditions, adequate debridement and saline irrigation are done followed by paraffin-impregnated gauze pieces applied in at least two layers over the wound in such a way that the bowel is completely covered. It serves as a protective layer, and the purpose of this layer is to completely prevent contact between the bowel and the polyurethane (PU) foam. The foam is cut as per the wound size and placed over paraffin gauze in such a way that it has contact with all the edges. An adhesive drape is then applied over the foam. A 2-cm hole is made at the center of this drape to allow a suction drain to fit over it. The suction tube is then connected to a commercially available VAC device. The negative pressure was set at a range of 75-100 mmHg, either in a continuous or intermittent mode. The dressings were changed every 48-72 hours depending on the exudates collected in the canister. Therapy continued until granulation or apposition of tissue is achieved and aborted in case of excessive pain or bleeding. |
