![]() ![]() The length of hospital stay was highest in the open OPM group and lowest in the open IPSDM group (p = 0.450). The operative time was found to be significantly shorter in open IPSDM (p < 0.001). The overall complication rate was highest in the open OPM group (48.3%) and lowest in the open IPSDM group (27%) (p = 0.092). There was no difference in mortality rates between the groups (p = 0.450). Although no recurrence was observed in the open IPSDM group, no significant difference was observed between the groups (p = 0.099). There was no significant difference between groups for medical complications (p = 0.540). Total surgery complications were significantly higher in the laparoscopic IPSDM group (15%) (p = 0.002). Total wound complications were significantly higher in the open OPM group (30%) (p = 0.009). Wound complications occurred in 26.7% of patients, surgical complications in 3.2%, medical complications in 6.5%, recurrence in 9.2%, and mortality in 0.8% of patients. Of the patients, 81.9% were operated on with the open OPM, 10.9% with the laparoscopic IPSDM, and 7.1% with the open IPSDM. Results Of the patients, 141 were male and 225 were female, and the mean age was 58.0 ± 28 years. Treatment methods were compared according to the demographic characteristics of the patients and the postoperative complication rates. Postoperative complications were divided into five groups as follows: wound complications, complications due to surgical procedures, medical complications, recurrences, and mortality. Patients were divided into three groups according to the surgical method used: open onlay prolene mesh (OPM) method, laparoscopic intraperitoneal sublay dual mesh (IPSDM) method, and open IPSDM method. Methods Between 20, 366 patients with incisional hernias with facial defects larger than 10 cm in a tertiary medical faculty hospital located in eastern Turkey were analyzed. ![]() The aim of this study is to compare the results of the three most common surgical treatment methods used in a tertiary university hospital for the repair of large incisional hernias in terms of patients' characteristics, recurrence, and complication rates of the treatment methods. In addition, there is no evidence-based consensus in the literature regarding the optimal surgical treatment of large incisional hernias. ![]() For this reason, it is a more difficult and experience-requiring application for surgeons. ![]() Surgical repairs of large incisional hernias have higher complications and recurrence rates compared to smaller incisional hernia repairs. Then, we discuss optimum power allocation for user fairness in terms of error performance of users and propose a novel power allocation scheme which achieves maximum user fairness.Introduction Incisional hernias are one of the most common complications after abdominal surgery. All theoretical analysis is validated via computer simulations. We derive exact bit error probabilities (BEPs) in closed-forms. In this paper, we analyze error performance of NOMA systems with imperfect SIC and channel estimation errors, much more practical scenario. However, all literature has been devoted to analyze error performance of NOMA systems with the perfect channel state information (CSI) at the receivers which is very strict/unreasonable assumption. In addition to this imperfect SIC effect, the error performance will get worse with the channel estimation errors just as in all wireless communications systems. In NOMA schemes, the effect of imperfect successive interference canceler (SIC) has dominant effect on the error performances.
