Midline Laparotomy Clinical Trial
Official title:
( Comparison Between ) Conventional and Modified Smead Jones Method for Abdominal Mass Closure in Emergency Midline Laparotomy
The occurrence of sudden disruption of abdominal wall laparotomy wound is a major disaster and a major psychological trauma to the patient . Acute wound dehiscence is defined as postoperative separation of the abdominal musculoaponeurotic layers within 30 days after operation. Many risk factors were incriminated in causation of burst abdomen including malnutrition, anemia, hypo-proteinemia, pre and post-operative prolonged steroid therapy, peritonitis, malignancy, jaundice, uremia and post-operative abdominal distension or cough. Wound dehiscence may be related to the technique of closure of abdomen and the sutures used. Numerous studies have been conducted evaluating many closure techniques and suture materials. There is a number of studies evaluating various closure techniques and suture materials to prevent wound dehiscence following emergency midline laparotomy. In developing countries such as India, most patients operated as an emergency develop wound dehiscence such as they have prolonged intraperitoneal sepsis and malnutrition. The current opinion for closure of a midline incision is mass closure with non-absorbable or slowly absorbable suture . Tension is distributed evenly along the length of the wound. The standard technique for abdominal closure is 'mass closure' (closing all layers of the abdominal wall, excluding the skin), usually with nonabsorbable sutures, although 'slow-resorbing' sutures such as polydioxanone (PDS) are also widely used . In Smead-Jones method of closure tension between two loops is distributed in such a way that the fascial edges are well approximated. Originally described method was interrupted. Continuous method has advantage of being faster and has less risk of wound dehiscence due to dynamic distribution of increased tension in postoperative period due to see-saw effect. We proposed modification of original Smead-Jones technique by doing it in continuous manner to increase the benefits and found this method to be fast, cost-effective, equally effective in controlling wound infection and better than interrupted technique to prevent wound dehiscence.
