Öğe Can the Drain Fluid pH Predict Anastomotic Leakage after Sleeve Gastrectomy?(Zamensalamati Publ Co, 2022) Kutluer, Nizamettin; Dogan, Serhat; Aksu, Ali; Ayyildiz, Hakan; Kalayci, Mehmet; Karagoz, Zuhal Karaca; Ozkan, ZeynepBackground: Laparoscopic Sleeve Gastrectomy is the most common type of surgical treatment for morbid obesity. One of the most important complications is leakage from the stapler line. Early detection of a leakage is important in preventing undesirable events. Objectives: The aim of this study was to evaluate the predictive value of postoperative drain fluid pH on early detection of leakage. Methods: This study was performed with 63 patients including 33 patients who underwent laparoscopic sleeve gastrectomy for morbid obesity (Group SG) and 30 patients who underwent laparoscopic cholecystectomy (Group LC), as the control group. Fluid sample was obtained after surgery with intra-abdominal drain. The pH value of this fluid was measured using a pH meter at the Ohaus device in the biochemistry laboratory of study hospital. Results: When the differences in the mean pH values of patients who underwent obesity surgery and gallbladder surgery were evaluated; no statistically significant difference was found between the mean pH value of patients (p: 0.808> 0.05). Conclusion: None of our patient had leakage and unable to demonstrate how would be the drain fluid pH value if there was a leak, we suggest that drain fluid pH would not be a suitable alarming sign for a leakage in the early period. Because we know that most of the leaks occur at the proximal part of the stomach and that there is more saliva drainage through the line of leakage. Although it is known that the acidic fluid of the stomach can be drained from the same leak in this condition, it is not unlikely that saliva can bring the pH to normal levels. Therefore, if the pH of the drain fluid is close to normal, it is meaning that there is no leakage from the site.Öğe Is gastroscopy necessary before bariatric surgery?(Baishideng Publishing Group Inc, 2022) Kanat, Burhan Hakan; Dogan, SerhatObesity is the abnormal accumulation of fat or adipose tissue in the body. It has become a serious health problem in the world in the last 50 years and is considered a pandemic. Body mass index is a widely used classification. Thus, obese individuals can be easily classified and standardized. Obesity is the second cause of preventable deaths after smoking. Obesity significantly increases mortality and morbidity. We thought of preparing a publication about routine procedures for the preoperative evaluation of obesity. The question that we asked as bariatric and metabolic surgeons but which was not exactly answered in the literature was Is esophagogastroduodenoscopy (EGD) necessary before bariatric surgery? We found different answers in our literature review. The European Association of Endoscopic Surgery guidelines recommend EGD for all bariatric procedures. They strongly recommend it for Roux-en-Y gastric bypass (RYGB). As a result of a recent study by the members of the British Obesity & Metabolic Surgery Society, preoperative EGD is routinely recommended for patients undergoing sleeve gastrectomy, even if they are asymptomatic, but not recommended for RYGB. It is recommended for symptomatic patients scheduled for RYGB. According to the International Sleeve Gastrectomy Expert Panel Consensus Statement, preoperative EGD is definitely recommended for patients scheduled for sleeve gastrectomy, but its routine use for RYGB is controversial. However, a different view is that the American Society for Gastrointestinal Endoscopy recommends endoscopy only for symptomatic patients scheduled for bariatric surgery. In the literature, the primary goal of EGD recommended for sleeve gastrectomy has been interpreted as determining esophagitis caused by gastroesophageal reflux. In the light of the literature, it is stated that this procedure is not necessary in America, while it is routinely recommended in the European continent. Considering medicolegal cases that may occur in the future, we are in favor of performing EGD before bariatric surgery. In conclusion, EGD before bariatric surgery is insurance for both patients and physicians. There is a need for larger and prospective studies to reach more precise conclusions on the subject.Öğe Jejunal diverticulitis(2018) Dogan, Serhat; Erikoglu, MehmetÖğe A medical approach to the treatment of atraumatic spontaneous spleen ruptures(2017) Dogan, Serhat; Gundes, Ebubekir; Donder, Yunus; Gulcan, Huseyin; Baburoglu, MehmetÖğe A rare case from a young surgeon: Dermofibrosarcoma protuberans(2017) Dogan, Serhat; Gundes, Ebubekir; Baz, VahideWe present a rare case of Dermatofibrosarcoma protuberans (DFSP) as a case report. A 65 years old man has been admitted with complaints of swelling in the left arm region for approximately five years. Local excision was performed with preliminary diagnosis of lipoma. The pathology was reported as DFSP. The borders of the surgery were positive. Call back the patient to the hospital and re excision was done. Surgical borders are reported as clean. As a new surgeon, we wanted to present this rare case to medical literature.
