Öğe Comparison of crystallized phenol treatment and simple primary closure methods for pilonidal sinus disease(International College of Surgeons, 2019) Türkoǧlu, Ahmet; Bozdaǧ, Zübeyir; Gümüş, Metehan; Oǧuz, Abdullah; Gül, Mesut; Yılmaz, Ahmet; Arıkanoğlu, ZülfüThe objective of the study was to compare the results of the patients treated with crystallized phenol treatment (CPT) or simple primary closure (SPC) for pilonidal sinus disease (PSD). For PSD treatment, both SPC and CPT have the advantages of rapid recovery, minimal pain, and short hospital stay. Even though these two techniques can be used interchangeably in uncomplicated cases, there is not enough evidence about which method is superior. A total of 102 patients who underwent CPT (n = 57) and SPC (n = 45) for uncomplicated PSD were included in the study. In all of the cases, data were recorded and compared between CPT and SPC groups, including age, gender, duration of the symptoms, hospital stay, complications, healing time, and recurrence. The mean age was 25.6 years and the male-to-female ratio was 93:9. The SPC and CPT groups were similar in terms of age, gender, duration of symptoms, complications, and healing time. The CPT group did not require hospitalization or anesthetic procedure in addition to local anesthesia, but the SPC group required a median of 1 day (range, 1–3 days) of hospitalization, and 3 patients (6.7%) needed spinal anesthesia. During a median of 27.5 months’ follow-up, the recurrence rate in the CPT group (6 patients; 10.5%) was lower than in the SPC group (13 patients; 28.9%). Both hospital stay and recurrence rates were better in the CPT group. Healing time and complication rates were similar in both methods. Based on these results, we suggest that CPT should be preferred to SPC in uncomplicated cases.Öğe Investigation of antioxidant effects of rosmarinic acid on liver, lung and kidney in rats: A biochemical and histopathological study(Via Medica, 2020) Oǧuz, Abdullah; Böyük, Abdullah; Ekinci, Aysun; Alabalık, Ulaş; Türkoǧlu, Ahmet; Tuncer, Cudi M.; Ekingen, Arzu; Deveci, Engin; Gültürk, Barış; Aday, U.Background: The aim of the study was to investigate the protective effects of rosmarinic acid in rats exposed to hepatic ischaemia/reperfusion (I/R) injury. Materials and methods: Thirty-two rats were randomly classified into four groups of 8 rats each: laparotomy without medication, rosmarinic acid (dose of 50 mg/kg via oral gavage) followed by laparotomy, laparotomy followed by hepatic I/R, and hepatic I/R with rosmarinic acid. Serum aspartate aminotransferase, alanine aminotransferase, and malondialdehyde levels and total oxidant activity and total antioxidant capacity levels of the liver, lung, and kidney were assessed. The histopathologic assessment was also performed. Results: Rosmarinic acid significantly reduced liver function test parameters and decreased oxidative stress and abnormal histopathologic findings in the liver. The oxidative stress in the lung significantly increased in the I/R group but significantly decreased in the I/R + rosmarinic acid group due to the addition of rosmarinic acid. Rosmarinic acid led to no reduction in oxidative stress in kidney following hepatic I/R injury. There were no statistically significant differences among the groups regarding histopathologic changes in kidney and lung sections. Conclusions: Rosmarinic acid has antioxidant properties and is an effective hepatoprotective agent. However, although rosmarinic acid provides useful effects in the lung by increasing antioxidant capacity and reducing oxidative stress after I/R injury, it does not ameliorate histopathologic changes. These findings suggest that rosmarinic acid is likely to provide favourable outcomes in the treatment of hepatic I/R injury. CopyrightÖğe Laparoscopic splenectomy: Clip ligation or en-bloc stapling?(Bilimsel Tip Yayinevi, 2019) Türkoǧlu, Ahmet; Oǧuz, Abdullah; Yaman, Gizem; Gül, Mesut; Ülger, Burak VeliObjective: Various techniques are used in the management of splenic hilum during laparoscopic splenectomy. Among them, the most used ones are polymer clips, en-bloc stapling and ultrasonic devices. To the best of our knowledge, there is no study in the literature comparing the results of clip and stapler techniques. This study was aimed to compare our results of clip ligation and en-bloc stapling of the splenic hilum. Material and Methods: The records of 67 patients undergoing laparoscopic splenectomy between December 2012 and October 2017 were reviewed. Patients were divided into two groups according to surgical method (stapler group: 26 patients and clip group: 41 patients). Patient age, sex, diagnosis, surgical technique, operation time, spleen dimensions, perioperative complications, postoperative hospital stay, blood transfusions, postoperative thrombocyte and hemoglobin levels were recorded. Results: Operating time was median 115 min (75-230) in the stapler group and 120 min (60-210) in the clip group, and there was no significant difference between the groups (p= 0.2593). There were no significant difference between the groups in terms of the postoperative complications (p= 0.59). Postoperative hospital stay was median 3.5 (2-8) days in the stapler group and 3 (2-6) days in the clip group with no significant difference (p= 0.0733). Conclusion: Clip ligation and en-bloc stapling techniques have no superiority over each other. Our results also showed that both techniques are safe and feasible. We suggest opting for the method according to the surgeon’s experience and hospital facilities.Öğe Prognostic significance of pretreatment serum lactate dehydrogenase-to-albumin ratio in gastric cancer(Termedia Publishing House Ltd., 2020) Aday, Ulaş; Tatlı, Faruk; Akpulat, Faik V.; İnan, Mazlum; Kafadar, Mehmet Tolga; Bilge, Hüseyin; Başol, Ömer; Oǧuz, AbdullahAim of the study: To investigate the prognostic role of lactate dehydrogenase-to-albumin ratio (LAR) in gastric cancer patients undergoing curative resection. Material and methods: A retrospective study was conducted including resectable gastric cancer patients. According to the time-dependent receiver operating characteristics (ROC) analysis, the optimal threshold for pretreatment LAR was 5.5. The Kaplan-Meier method, Cox regression univariate and multivariate analyses were used to analyze the prognostic factors for disease-free survival and overall survival (OS). Results: The study cohort consisted of 81 patients, mean age was 60.2 ±13.8 (range, 29-87) years and 55 (67.9%) were male. The median OS time was 34.8 and 45 months in patients with LAR ≥ 5.5 (n = 50) and LAR < 5.5 (n = 31), respectively. Kaplan-Meier curves showed that with the increase in LAR there was reduced survival, but it was not statistically significant (p = 0.278). Multivariate analyses revealed that the positive lymph node ratio above 20% was an independent predictor in resectable gastric cancer patients (OR = 6.281, 95% CI: 1.135-34.767, p = 0.035). Conclusions: With the increase in LAR survival in gastric cancer decreased, but it was not statistically significant. Studies involving a large patient series are needed.
