Sacrococcygeal pilonidal sinus disease affects younger persons, resulting in long-term loss of productive power. It also has a high rate of morbidity because there is no standard treatment approved by all surgeons. In this study, early and late results of 85 cases treated with excision and Limberg flap in our clinic were investigated. The patients were followed for 9-120 months. The complication rate was 4.7% and the long-term relapse rate was 3.5: Insufficient personal hygiene and inadequate excision were the main causes for recurrence. On the basis of the literature and our previous experiences, we conclude that the Limberg flap is the ideal treatment for sacrococcygeal pilonidal sinus disease with low morbidity, mortality and recurrence rates.

The aim of this study is to analyze the risk factors for complications and recurrence in pilonidal sinus disease. The prospective study consisted of 144 patients with pilonidal sinus disease who were operated on at Dicle University Medical Faculty, Department of General Surgery, between February 2008 and December 2010. Patients receiving the Limberg flap totaled 106 (73.6%), while 38 (26.4%) had primary closure. Postoperative complications developed in 42 subjects (29.2%), and recurrence occurred in 19 (13.2%). The Limberg flap method was statistically considered as a risk factor for postoperative complications (P = 0.039). Regarding recurrence, family tendency (P = 0.011), sinus number (P = 0.005), cavity diameter (P = 0.002), and primary closure (P = 0.001) were found to be risk factors. Postoperative complication rate is higher in the Limberg flap method than primary closure method. The risk of recurrence is related to family tendency, sinus number, cavity diameter and anesthesia type and is also higher in primary closure.

The objective of this study is to discuss the effective factors on morbidity and mortality in patients who were operated on for acute mesenteric ischemia. Between 2006 and 2011, 95 patients, who underwent emergent surgery for acute mesenteric ischemia, were analyzed retrospectively. The study group consisted of 56 men (58.9%) and 39 women (41.1%), with an average age of 68.4 ± 14.4 years. Elapsed time between the onset of the symptoms and the surgical operation was less than 24 hours in 47 (49.5%) cases, and more than 24 hours in 48 cases (50.5%) (P , 0.001). Although all of the patients had intestinal necroses, colon involvement was seen in 38 patients, and mortality was higher in this group of patients (P , 0.001). Mortality rate was 42.1%. This was higher in older patients, those with increased leukocyte levels, increased elapsed time to laparotomy, and when the colon was involved.

Malignant mesothelioma is a rare but highly lethal form of cancer that affects the serosal membranes. Malignant peritoneal mesothelioma (MPM) is the second most common form of malignant mesothelioma (pleural mesothelioma is the most common). The aim of this study was to evaluate prognostic factors influencing the survival of patients with MPM.A retrospective analysis was performed on 35 patients who were admitted to our hospital between March 2005 and July 2013. The patients' demographic and clinical data, laboratory results, radiological signs, Eastern Cooperative Oncology Group (ECOG) performance status (PS), and treatment outcomes were evaluated.The mean age of the 35 patients was 59.0±14.4 years, the mean survival time was 16.2±12.9 months, and the majority of the histopathological types of MPM were epithelial (68.6%). 82.9% of the patients had been exposed to asbestos, and the mean duration of exposure was 28.3±14.5 years. The most frequent symptoms were abdominal distention/pain, weight loss, dyspnea, and chest pain. The mean interval between the onset of symptoms and the diagnosis was 4.6±3.3 months. Platinum-based combination chemotherapy in combination with supportive care was used in the treatment of 68.6% of the patients, while supportive treatment alone was used in the others. Our results revealed that patients who were >60 years old (p=0.019), who were exposed to asbestos >20 years (p=0.033), who had an ECOG PS of 3 (p=0.000) were more likely to have a poor MPM prognosis.In conclusion, increased age, duration of environmental asbestos exposure and ECOG PS are important factors that influence the prognosis of MPM patients.

As a serious complication of cholelithiasis, gangrenous cholecystitis presents greater mortality than noncomplicated cholecystitis. The aim of this study was to specify the risk factors on mortality. 107 consecutive patients who underwent surgery due to gangrenous cholecystitis between January 1997 and October 2011 were investigated retrospectively. The study included 60 (56.1%) females and 47 (43.9%) males, with a mean age of 60.7 6 16.4 (21-88) years. Cardiovascular diseases were the most frequently accompanying medical issues (24.3%). Thirty-six complications (33.6%) developed in 29 patients, and surgical site infection was proven as the most common. Longer delay time prior to hospital admission, low white blood cell count, presence of diabetes mellitus, higher blood levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and total bilirubin, pericholecystic fluid in abdominal ultrasonography, and conversion from laparoscopic surgery to open surgery were identified as risk factors affecting mortality (P , 0.001, P ¼ 0.001, P ¼ 0.044, P ¼ 0.005, P ¼ 0.049, P ¼ 0.009, P ¼ 0.022, P ¼ 0.011, and P ¼ 0.004, respectively). Longer delay time prior to hospital admission and low white blood cell count were determined as independent risk factors affecting mortality.
