+ – + + – - – - – 4/10 Surv. Elderly patients and history of COPD are present in the 67% of cases, cancer and sepsis in the 53,3% of cases. The presence of anemia, diabetes mellitus and the history of received chemotherapy or radiotherapy are 40% in iur patients. Malnutrition and obesity are present in one third of our patients. Only 20% of patients did receive treatment with steroids in the last 12 months. Concerning the surgical history and the postoperative

morbidity, the results are listed in table 3.

Three patients (20%) developed wound dehiscence after their initial discharge and were readmitted to our hospital. Concerning the type of incision or the abdominal closure, only the presence of interrupted suturing of linea alba (10/14) patients plays a role in the wound dehiscence. This factor factor

is a hypoestimated parameter in he past as a possible risk factor. All patients are reoperated after the wound dehiscence diagnosis and three of them (20%) died due to postoperative complication of reoperation. In one of them recurrence of wound dehiscence was observed. Regarding the preoperative risk factors, three from four (75%) patients with 7 or more risk factors did die. The abdominal closure was performed using mesh in 4 cases, a flap in 2 cases and a continuous suturing in 9 cases. Retention suture were used in 2 cases. Discussion Wound dehiscence is a mechanical failure of wound healing, remains a problem and it can be affected by multiple factors. Pre-operative conditions especially in elective operations should be recommended to reduce or eliminate the risk.
