Direct pulp capping with RetroMTA (BioMTA, Daejeon, Korea)

Dental Pulp Exposure

The study included seven caries-free third molars from three adults. These teeth were subjected to pulp exposure, direct capping with RetroMTA, and restoration with a composite resin. Seven months later, the teeth were clinically and radiographically evaluated. The teeth were then extracted and subjected to histological processing and evaluation.

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.

Incisional Hernia

Malignancy

Mass closure technique

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

surgical site infections, defined and classified according to the CDC (Centers for Disease Control) recommendations

Complications of grade III or higher according to Clavien-Dindo classification

Duration of postoperative hospitalization in days

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.
