Öğe Changes in cerebral oxygen saturation with the Trendelenburg position and increased intraabdominal pressure in laparocopic rectal surgery(Turkish Surgical Assoc, 2022) Alkan, Selman; Cakir, Murat; Senturk, Mustafa; Varman, Alper; Buyukbezirci, Gulcin; Yildirim, Mehmet Aykut; Bicer, MehmetObjective: Position changes and increased intra-abdominal pressure in laparoscopic interventions lead to some physiopathological changes. There is no definite information in the literature regarding cerebral oxygen saturation in patients undergoing colorectal surgery. Our aim was to investigate whether there is oxygen saturation change in the brain tissue in pneumoperitoneum and the Trendelenburg position during laparoscopic rectal surgery. Material and Methods: Cerebral oxygen saturation was measured in 35 patients who underwent laparoscopic rectal surgery in the Trendelenburg position. Measurements were made under general anesthesia in the pneumoperitoneum and the Trendelenburg position. Results: The values that are statistically affected by the position are systolic blood pressure, mean arterial blood pressure and cerebral oxygen saturation. The Trendelenburg position does not disturb the cerebral oxygen saturation and it causes an increase in saturation. After pneumoperitoneum occurred, changes in systolic blood pressure, mean arterial blood pressure and brain oxygen saturation were detected. Cerebral oxygen saturation increases with the formation of pneumoperitoneum. Conclusion: The Trendelenburg position and increased intraabdominal pressure during laparoscopic rectal surgery do not impair brain oxygen saturation.Öğe Complications and recurrence after Karydakis Flap surgery(Index Copernicus Int, 2021) Cakir, Murat; Bicer, MehmetIntroduction: Pilonidal sinus is a disease affecting individuals at young age. Numerous surgical methods have been described in the treatment of pilonidal sinus disease. Currently, there is no treatment method providing a rapid recovery with low recurrence risk. Aim: In this study, we aimed to evaluate the results of our patients who underwent Karydakis surgery. Material and methods: Results of 112 patients operated on between 2012 and 2019 were retrospectively evaluated. Only the patients who underwent Karydakis surgery were included in the study. Results: Of all patients, 20 were female and 92 were male. The mean age was 21 years in the female and 20.8 years in the male patients. The mean BMI was 29.6 kg/m(2). The patients were followed up for a mean of 28 months. Postoperative length of stay in hospital was 2.1 days. The complications included wound dehiscence in 10.2%, infection in 3.6%, and bleeding (hematome) in 7.1%. Four patients developed recurrence during follow-up. Conclusions: Karydakis surgery is a preferable surgical technique with low rates of complications and recurrence.Öğe Lifestyle and Chronic Constipation in Medical Students(Hindawi Ltd, 2021) Yildirim, Mehmet Aykut; Cakir, Murat; Bicer, Mehmet; Senturk, Mustafa; Yonar, Harun; Gur, Merve Nur; Akiner, Zeliha NurAim. Constipation is one of the most common complaints of the digestive system indicated with an increase in defecation frequency, difficulty in defecation, and hard and strained defecation. Environmental, personal, and genetic factors may be affecting constipation although the affecting factors have not yet been thoroughly explained. The aim of this study was to investigate constipation frequency and lifestyles in medical students. Method. The population was selected among medical students for the study, which was planned as a survey study. Demographic data of all the participants and the factors suggested to affect constipation were questioned and analyzed. Results. The study covered a total of 425 medical students. Among the students reporting constipation, 2.86% were in their first year of medical school, while 7.53% were in the third year and 9.09% were in the sixth year. The rate of students reporting constipation and familial history was statistically significant. While regular eating habits were reported in the first and third years, this rate was much lower in the sixth year group working at clinical departments. The results of our study did not reveal any significant relationship between daily intake of water and constipation. There was, however, a significant relationship between stress and constipation. Conclusion. The results of our study showed that medical education did not curb constipation frequency. We believe that stress is significant in constipation. The data we collected indicate that regular eating habits and excess liquid intake are not as effective as suggested in the treatment of constipation.Öğe Reasons for transition to open surgery in laparoscopic cholecystectomy(Bayrakol Medical Publisher, 2021) Senturk, Mustafa; Cakir, Murat; Bicer, Mehmet; Yildirim, Mehmet AykutAim: Laparoscopic cholecystectomy is a minimally invasive surgical technique that has become widespread since the 1980s. Many factors are effective in the conversion to open surgery. This study aimed to investigate the rates and reasons for the conversion to open in laparoscopic cholecystectomy surgeries in our hospital. Material and Methods: This study aimed to examine 3263 cholecystectomy cases with the conversion to open during surgery between June 2014 and June 2019. Patients were examined in terms of age, sex, comorbidities, acute cholecystitis attack status, previous surgery, adhesion, gallbladder wall thickness, revealing surgical anatomical structure, surgical complications, length of hospital stay, and mortality. The results were evaluated statistically. Results: Data of 70 patients, who were performed laparoscopic cholecystectomy with the conversion to open surgery during the procedure, were reviewed. The conversion rate was 2.3%. Among the patients, 28 were female and 42 were male. Sixty-two of the patients had an episode of acute cholecystitis. The most common reason for the conversion was that the anatomy could not be revealed . Discussion: It should be kept in mind that laparoscopic cholecystectomy surgery, which is interpreted as a simple surgical procedure, can always be converted to an open surgery and there may be vital complications.
