Öğe Acute abdomen due to spilled gallstones: a diagnostic dilemma 10 years after laparoscopic cholecystectomy(Oxford University Press, 2020) Kafadar, Mehmet Tolga; Çetinkaya, İsmail; Aday, Ulaş; Başol, Ömer; Bilge, HüseyinLaparoscopic cholecystectomy (LC) carries a significant risk of gallbladder perforation and resulting scattering of bile stones into the abdominal cavity. The retrieval of the spilled stones is not always possible by laparoscopic technique. Most cases do not create long-term problems, although some cases may be complicated in future and create uncertainties regarding the correct diagnosis. Diagnosis can be difficult, and in most cases the patient may require open surgery for management of these complications. Herein, we report a case of acute abdomen due to spilled stones occurring 10 years after LC. In the first stage, definitive diagnosis could not be made with computed tomography examination. Finally, the patient was diagnosed with explorative laparotomyÖğe Comparison of local rosmarinic acid and topical dexpanthenol applications on wound healing in a rat experimental wound model(Via Medica, 2021) Küba, M. C.; Türkoǧlu, Ahmet; Oğuz, Abdullah; Tuncer, Cudi Mehmet; Kaya, Suheyla; Başol, Ömer; Bilge, Hüseyin; Tatlı, FarukBackground: The aim of the study was to compare the effects of rosmarinic acid and dexpanthenol in a rat experimental wound model. Materials and methods: Twenty-four Wistar albino rats weighing 200-250 g were randomly divided into three groups. After 2-cm full-thickness skin defects were created, the wounds were washed with sterile 0.9% NaCl solution. After washing, the control group was left untreated, the second group received 5% dexpanthenol cream, and the third group received 10% rosmarinic acid cream. Before excision, the skin was evaluated macroscopically by measuring the reduction in wound size; after excision, histological examination (epithelisation, inflammation, fibrosis, granulation) was performed. Results: Macroscopic comparison of the wound sizes showed that group 3 showed a statistically significant difference in wound size reduction compared to the other two groups. Histopathological examination showed that there was no statistically significant difference between the groups. We found that the rosmarinic acid group had greater wound size reduction than the other two groups. However, epithelialisation was detected in fewer cases. Conclusions: We believe that rosmarinic acid can be used as a topical cream for wound healing, as it leads to significant reduction in wound size, resulting in fewer scars.Öğe Comparison of the results of sleeve gastrectomy, gastric pilication and liragulitide in obese rats(2023) Bilge, Hüseyin; Başol, Ömer; Yıldızhan, Eda; Ülger, Burak Veli; Temiz, Hakan; Akkuş, Murat; Yıldızhan, I.Obesity, which is generally seen in adults, is a serious health problem. Diseases caused by obesity are among the leading causes of death worldwide. Liraglutide (LG) is an analogue of glucagon-like peptide-1, which slows gastrointestinal motility, resulting in decreased food consumption. Gastric plication (GP) and sleeve gastrectomy (SG) is the reduction of stomach volume by surgical means. We examined and compared the body mass index (BMI) changes, metabolic changes and changes in gastric histology in obese rats after LG injection with surgical methods such as SG and GP. In this research, 35 Wistar Albino female rats were used. Rats were divided into 5 groups with 7 rats in each group. Group (G) 1: The control group, fed with a normal calorie diet for 8 weeks. G 2: Sham group, G 3: SG group, G 4: GP group and G 5: LG group, fed with high-calorie feed for 4 weeks. At the end of the 4th week, the study was terminated by making appropriate interventions for the groups. When the blood glucose (BG) levels measured at the beginning, 4th week and 8th week of the experiment were evaluated, it was monitored that the BG level at the 8th week was the lowest in the LG group (p<0.05). It was observed that the preop Ghrelin and Leptin levels of the LG group were lower than those of the SG and GP groups (p<0.05). As a consequence of our metabolic investigations, we observed that the use of LG is at least as effective as SG.Öğe Effectiveness of boric acid in preventing acrylamide-conducted brain damage in rats(Merthan Tunay, 2023) Yıldızhan, Eda; Ülger, Burak Veli; Gündüz, Ercan; Akkuş, Murat; Bilge, HüseyinAim: Acrylamide (ACR) is a water-soluble neurotoxic substance that has been widely researched in recent years. Boric acid (BA) is a component that does not have a toxic effect when taken at low concentrations and has a cystotoxic activity. Studies have reported that BA has antioxidant effects. In this study, we aimed to examine the protective efficacy of BA against the toxic damage that ACR may cause in the brain tissue. Methods: In this study, 28 Wistar Albino male rats with an average weight of 320-400 grams were used. In our study, ACR was administered intraperitoneally (i.p.) at a dose of 50 mg/kg for 14 days, while BA was administered orally (p.o.) with a dose of 200 mg/kg for 14 days. Group 1 (n=7): It is the control group and no medication was administered for 14 days. Group 2 (n=7): ACR group, Group 3 (n=7): BA group and Group 4 (n=7): ACR + BA group. Results: The comparison between the groups in terms of serum Total Oxidant Status (TOS) and Malondialdehyde (MDA) analysis revealed that the highest MDA level was in the ACR group. The MDA and TOS levels of the ACR+BA group were significantly lower than the ACR group (p<0.05). Conclusions: Our study revealed that BA has a protective effect in the prevention of neurotoxicity due to oxidative stress after ACR applicationÖğe Median arcuate ligament (Dunbar) syndrome: Laparoscopic management and clinical outcomes of a single centre(Wolters Kluwer Medknow Publications, 2021) Kafadar, Mehmet Tolga; Oğuz, Abdullah; Aday, Ulaş; Bilge, Hüseyin; Başol, ÖmerBackground: Median arcuate ligament syndrome (MALS) is a condition characterised by chronic abdominal symptoms associated with median arcuate ligament (MAL) compression of the coeliac artery. Aim: In this observational study, we aimed to evaluate the outcomes of laparoscopic treatment in patients with MALS. Materials and Methods: The data of ten patients with MALS who were subjected to laparoscopic sectioning of the MAL were retrospectively reviewed. The following data were evaluated: age, gender, clinical and diagnostic test findings, American Society of Anaesthesiologists score, operative findings and complications and mortality, hospital stay duration and hospital readmission. The diagnosis of MALS was established by computed tomography (CT) angiography. Results: Six (60%) of ten patients with MALS were female and four (40%) were male. The mean age was 42.4 +/- 12.3. The main symptoms were epigastric pain (100%) and weight loss (60%). CT angiography showed high-grade stenosis of the anterior wall of the proximal coeliac trunk and post-stenotic dilation caused by extrinsic compression of the MAL. Surgical procedure was uneventful in all patients. Operating time was 155.5 min (120-200) and intra-operative blood loss was 150 ml (100-250). Length of stay was 3.1 day (2-9), with no mortality. The post-operative complications developed in two female patients. One of them developed ileus and the other patient developed pulmonary thromboembolism. At 6-month follow-up, all patients were asymptomatic. Conclusion: Laparoscopic decompression is an effective treatment for MALS and can provide symptomatic relief. This method may be the preferred modality of treatment in view of its lack of morbidity and good results.Öğe Perineal and abdominal approaches in the surgical treatment of rectal prolapse: Our 10-year clinical experience(İstanbul Bağcılar Eğitim ve Araştırma Hastanesi, 2021) Başol, Ömer; Bilge, Hüseyin; Akpulat, Faik Veysel; Yaman, Gizem; Oğuz, AbdullahObjective: Rectal prolapse is a rare condition characterized by protrusion of the rectum with all its layers from the anus. It is a disease that causes social and functional problems. In this study, it was aimed to investigate the abdominal and perineal approaches together with postoperative early and late results in our patients who underwent surgical treatment for rectal prolapse. Method: The records of 39 patients who were operated on with the diagnosis of rectal prolapse between 2010 and 2020 in the Department of General Surgery, Dicle University Faculty of Medicine were evaluated retrospectively. Demographic and physical examination findings of the patients, surgical methods applied, early and late postoperative complications, recurrence and mortality rates were recorded. Results: The most common complaints on admission to the hospital were gas control disorder, difficulty in defecating and getting wet with mucus. On physical examination, stage 1 rectal prolapse was found in 12.8% of the patients, and full-thickness prolapse was found in the other patients. The mean age of 39 patients included in the study was 36 (14- 88) years. Of the patients included in the study, 14 (35.9%) were female and 25 (64.1%) were male. Surgery was performed with an abdominal and perineal approach in 53.8% of the patients, while laparoscopy was performed in 46.2%. The most frequently used abdominal surgical technique was Notaras (35.8%). The most common perineal approach technique was Altemeier (5.1%). Patients who underwent the perineal approach were older and had a shorter hospital stay, and it was often performed under regional anesthesia. Complications developed in the early postoperative period in 10.4% of the patients. The median hospital stay was 5 days (2-19) and the follow-up period was 13 months (9-19). Postoperative mortality did not occur in any of the patients. Hospital stay was significantly shorter in patients who underwent laparoscopic surgery. There was no statistical difference in terms of early postoperative complications and recurrence. Conclusion: Although more than a hundred surgical procedures have been described to date for the treatment of rectal prolapse, the ideal treatment method is still unclear. In terms of surgical treatment, the results of abdominal or perineal approaches to be applied are similar, considering the risk factors, patient findings and surgeon’s experience.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.Öğe The prognostic significance of serum lactate dehydrogenase to albumin ratio in pancreatic ductal adenocarcinoma(Hacettepe University Faculty of Medicine, 2023) Bilge, Hüseyin; Başol, Ömer; Demir, Baran; Oğuz, AbdullahObjective: This study was performed to investigate the prognostic role of lactate dehydrogenase/albumin ratio (LAR) and pancreatic ductal adenocarcinoma (PDAC) with initial curable resection treatment. Materials and Methods: This retrospective study was conducted with the data of patients with resectable PDAC. The (ROC) analysis showed that the optimal sill value for pretreatment LAR was 91.43 and this threshold value was used in other analyses. Univariate and multivariate analyses were performed to determine the prognostic factors for overall survival (OS). Results: Our study consisted of 70 patients with a mean age of 59.5±13.2 years and 37 (52,9%) women. OS was 50 months in LAR <91.43 (n = 32) patients and 27,7 months in LAR≥91.43 (n=38) patients, respectively. Kaplan–Meier curves showed that LAR≥91.43 was significantly associated with worse OS (p=0.029). Multivariate analyses proved that LAR was an independent predictor in resectable PDAC patients (p=0.017). Conclusion: Our results showed that a high pre-treatment LAR level was a unfavorable prognosticator in PDAC patients undergoing curative resection. LAR has the potential to be a prognostic biomarker in clinical practice.Öğe Protective effect of taxifolin in the prevention of cardiac tissue damage in liver ischemia and reperfusion injury: Experimental study(Merthan Tunay, 2023) Bilge, Hüseyin; Yıldızhan, İbrahim; Ülger, Burak Veli; Aday, Ulaş; Başol, Ömer; Çiçekçi, Kadriye; Yıldızhan, EdaAim: Liver ischemia and reperfusion (I/R) is a serious, irreversible health problem in clinical practice. Taxifolin (Tax) is an easy to obtain and use agent found in maritime pine bark, Douglas fir bark and Siberian larch wood. In this study, we examined the protective efficacy of Taxifolin in the correction of cardiac tissue damage that may develop in liver I/R damage. Methods: In our study, a total of 28 Wistar Albino rats, 8-10 weeks old, weighing 250-300 grams, were used. Group 1 (n=7): control group, Group 2 (n=7): Tax group with 50 mg/kg dose orally for 3 weeks, Group 3 (n=7): Liver I/R group for 30 minutes ischemia and 120 minutes of reperfusion were performed. Group 4 (n=7): Tax+Liver I/R group. Results: In our study, MDA analysis was performed to evaluate oxidative stress. In the statistical analysis of MDA values, we observed that there was a statistically significant difference between the serum MDA values of the Tax group and the Tax+Liver I/R group, and the MDA level of the Tax group was lower (p<0.05). In myocyte damage scoring, we observed that the liver I/R group had the highest damage score, while the damage score of the Tax+Liver I/R group was significantly lower than the I/R group (p<0.05). Conclusion: As a result of our study, we observed that there was an increase in serum MDA levels as a result of liver I/R and histopathological changes occurred in the heart tissue. However, Taxifolin has been successful in ameliorating this situation.
