Brief Summary

This study evaluates the abdominal closure technique in emergency surgery. Half of participants will be perform the classic Large Stitch technique, while the other half will undergo the Small Stitch technique.

Detailed Description

The closure of laparotomy is one of the most important challenges facing the surgeon.

The classic technique of wall closure is the Large Stitch technique that uses monofilament double-strand sutures with a SL/WL (Suture Lengh/Wound Lengh) 4:1 ratio, with a distance to the alba line and between each stitch of 1 cm.

Nowadays, the Small Stitch technique is accepted as the technique of choice for closure of laparotomies in programmed surgery. It is based on a very long-term monofilament absorbable synthetic suture of Poly-4-hydroxybutyrate (Monomax) 2/0 with HR (Half-circle Round body) 26 needle. Stitches should be given with a distance to the alba line of 0'5cm and 0'5 cm of separation between stitches.

There are very few studies about the role of Small Stitch technique in the field of Emergency Surgery where the increased morbidity of the patient and the higher rate of surgical wound infection can play a fundamental role, and could be improved with the use of new abdominal wall closure techniques.

Arm && Interventions

Group	Intervention	Description
Small Stitch	Monomax® 2/0 HR26	Patients requiring an urgent emergency laparotomy. The Small Stitch closure technique will be perform using a Monomax® 2/0 HR26 (Half-circle Round body): * It will be use a very long-term monofilament absorbable synthetic suture of Poly-4-hydroxybutyrate (Monomax) 2/0 with HR 26 needle (Half-circle Round body). * In the technique should be given at least 2 points for each wound cm, with a distance to the alba line of 0'5cm and 0'5 cm of separation between stitches. The closure starts from both ends, ending in the middle of the laparotomy with an overlap of at least 2 cm. The ratio between the length of the suture and the length of the wound should be at least 4:1.
Large Stitch	Monomax® 1 HR48	The intervention will be the classic large Stitch closure technique using a Monomax® 1 HR48 (Half-circle Round body). * It will be use a very long-term monofilament absorbable synthetic suture of Poly-4-hydroxybutyrate (Monomax) 1 with HR 48 needle (Half-circle Round body). * In the technique should be given 1 point for each wound cm, with a distance to the alba line of 1 cm and 1 cm of separation between stitches. The closure starts from both ends, ending in the middle of the laparotomy with an overlap of at least 2 cm. The ratio between the length of the suture and the length of the wound should be at least 4:1.

Primary Outcome Measures

Name	Time	Method
Efficacy of the small stitch technique defined by eventration rate	1 year	To determine the efficacy of the "Small stitch" technique versus the "Large Stitch" technique in the closure of midline laparotomy with respect to the production of eventration in patients undergoing urgent abdominal surgery.

Secondary Outcome Measures

Name	Time	Method
Efficacy of the small stitch technique defined by evisceration rate	1 year	To determine if the closure of the midline laparotomy with the "Small Stitch" technique in patients undergoing urgent abdominal surgery reduces the rate of evisceration.
Efficacy of the small stitch technique defined by improvement of quality of life	1 year	To determine if the closure of a midline laparotomy with the "Small Stitch" technique in patients undergoing urgent abdominal surgery improves the quality of life.
Efficacy of the small stitch technique defined by local complications rate	1 year	To determine whether the closure of midline laparotomy with the "Small Stitch" technique in patients undergoing urgent abdominal surgery reduces the local complications of the surgical wound defined by hematoma, seroma or wound infection.
Security of the small stitch technique	1 year	To determine the safety of the Small Stitch technique versus the "Large Stitch" technique in the closure of the midline laparotomy with respect to the incidence of adverse events and serious adverse events, the incidence of side effects related to the treatment and the incidence and the reasons for premature withdrawal of premature patient from the study.
