Abdominal cavity will be closed by a single layer of 2 continuous sutures beginning on the opposite ends of the wound towards the median line and involving peritoneum, transversalis fascia, posterior and anterior layer of rectus abdominis muscle fascia and, in case of incisions beyond the lateral border of rectus abdominis muscle, also the oblique abdominal muscles fascia.

Abdominal cavity will be closed with two separate layers of continuous sutures. The first layer will include peritoneum, transversalis fascia and posterior layer of the rectus abdominis muscle fascia. In case of incisions not exceeding the lateral border of rectus abdominis muscle, the second layer will involve only the anterior layer of the rectus abdominis muscle fascia. In case of incisions exceeding the lateral border of rectus abdominis muscle, the second layer will include internal oblique abdominal muscle fascia, external oblique abdominal muscle fascia and anterior layer of the rectus abdominis muscle fascia.

he first layer will include peritoneum, transversalis fascia and posterior layer of the rectus abdominis muscle fascia closed with 2 continuous sutures beginning at both ends of the wound. In case of incisions exceeding the lateral border of rectus abdominis muscle, the second layer of the continuous suture will start at the lateral border of rectus abdominis muscle, process laterally to the lateral end of the wound involving internal oblique abdominal muscle fascia. Subsequently, the suture will be led out on the anterior surface of the external oblique abdominal muscle, put through by the created loop in the medial direction and processed medially to close the external oblique abdominal muscle fascia and anterior layer of the rectus abdominis muscle fascia.

Risk Factors for Development of Incisional Hernia in Transverse Incisions

Study on the Risk of Incisional Hernia Development Following Transverse Epigastric Incisions in Patients Operated for Malignant Tumors

Development of burst abdomen in the immediate postoperative period (until discharge from hospital) or incisional hernia over a 2-year follow-up period (combined end-point). The follow-up protocol used for the assessment of incisional hernias at discharge from hospital and two control visits at 1 and 2 years postoperatively.

Quality of life assessed in EORTC QLQ-C30 questionnaire

The technique comprising continuous suture and mass closure will be compared to the technique 2 separate layers of continuous sutures.
Patients will be randomly assigned to one of the two techniques of abdominal closure during the operative procedure and after its main part has been completed, just before the beginning of closure of the abdominal cavity. Randomization will be performed in a 1:1 ratio and in blocks of 20 patients.

Neither the patients included in the study nor the investigators assessing the presence of incisional hernia during follow-up visits will be aware of the type of surgical technique used for abdominal closure (double-blinded study). Only the professionals present in the operating room during surgical procedure, including operator, assistants, anesthesiologist, and nurses, will be aware of the type of assigned intervention.

The edges of the 2PT/Epi will be infiltrated with 10ml of Bupivacaine 0.5%+Epinephrine 50mcg prior to suture placement.

The edges of the 2PT/Epi will be infiltrated with 10ml of NaCl 0.9% prior to suture placement.

Sham injection will be done using a syringe filled with 10ml of NaCl 0.9%, but the fluid will not be injected to the edges of the laceration but discarded. The sham injection will last no less than 10 seconds.

The specimen was divided into three parts after washing with sterilized saline, and one was ﬁxed by 2.5% glutaraldehyde solution immediately ，then coated with palladium gold for electron microscopic examination;one was fixed by 2.5% glutaraldehyde arsenate ,then embedded in Epon for transmission electron microscopy ; one was ﬁxed by 4% formalin, then embedded in parafﬁn for immunohistochemical analysis.

The expression analyzed by Immunohistochemistry.The stainings were graded semiquantitatively and the H-score was calculated using the following equation: H-score =∑Pi (i + 1), where i = intensity of staining with a value of 1, 2 or 3 (weak,moderate or strong, respectively) and Pi is the percentage of stained epithelial cells for each intensity, varying from 0 to 100%.

The specimens were mounted, coated with platinum, and examined by using a scanning electron microscope ( S-3000N, Hitachi, Tokyo, Japan). The pinopodes morphology evaluation was defined as: no pinopodes,developing pinopodes,fully developed pinopodes and regressing pinopodes. The semi-quantitative evaluation was defined as following:- (0%), + (<20%), ++ (20-50%) and +++(>50%).
