Öğe Does the intraoperative parathormone monitoring really affect surgical success in primary hyperparathyroidism?(Taylor & Francis Ltd, 2023) Ozdemir, Egemen; Ozden, Sabri; Tutuncu, Tanju; Daglar, Gul; Yuksek, Yunus NadiBackground Surgery is the only curative treatment option for primary hyperparathyroidism (PHPT). The intraoperative parathormone (IOPTH) monitoring is recommended to confirm that all pathological glands have been removed. This study aimed to evaluate the effect of IOPTH monitoring on the surgical success of parathyroidectomy performed for PHPT. Methods The demographic, biochemical, operative and pathological data of patients who underwent parathyroidectomy for PHPT in a single institute over a three-year period were retrospectively analyzed. Results The total number of patients included in the study was 182. The IOPTH monitoring had been performed in 92 patients (50.5%). The IOPTH monitoring had a clinical accuracy of 89.2%, sensitivity of 89.8%, and specificity of 75%. The rate of surgical success was 95.7% in the group with IOPTH monitoring and 91.1% in the group without this monitoring (p = .21). Of the 40 patients who underwent minimally invasive parathyroidectomy (MIP), 25 patients had IOPTH monitoring, and the surgery was successful for all these patients (100%). Surgical success was achieved in 14 (93.3%) patients who underwent MIP without IOPTH monitoring (p = .37). Conclusion The IOPTH monitoring is a reliable test with high accuracy. The lack of IOPTH monitoring may result in lower than acceptable surgical success rates. Even though preoperative localization studies are compatible with surgical findings, the IOPTH monitoring should also be undertaken, especially in patients scheduled for MIP for PHPT.Öğe An Evaluation of the Factors Affecting Failure of the Procedure in reoperated Thyroidectomies: A Retrospective Analysis(Sage Publications Inc, 2022) Comcali, Bulent; Ozdemir, Buket A.; Atas, Hakan; Ozdemir, Egemen; Tikici, Deniz; Saylam, BarisBackground The aim of this study was to determine the factors affecting procedure failure in revision thyroidectomy surgery. Methods A total of 148 patients applied with revision surgery were separated into 2 groups according to the surgical success status. Comparisons were made of the 2 groups of patients where residual tissue was totally excised (Group 1, n:132) and patients where residual tissue could not be completely excised (Group 2, n:16). The patients were examined in respect of factors affecting the success of the procedure. Results The patients comprised 133 (89.9%) females and 15 (10.1%) males with a mean age of 49.68 +/- 12.02 years. Surgical failure was observed in 7 patients as the lesion could not be determined despite the use of intraoperative USG, and in 9 patients because of weak signal or signal loss. The determination of residual tissue <= 25mm on preoperative USG examination was seen to have a significant negative effect on surgical success (r=-0.329, p0.001). The patient having undergone >= 3 previous operations was determined to have a negative effect on surgical success (r=-0.229, p=0.005), and nerve damage on the opposite side to the lesion in a previous surgical procedure was determined to be the most important factor with a negative effect on surgical success (r=-0.571, p<0.001). In multinomial logistic regression analysis of the factors affecting success, the preoperative presence of nerve damage in the contralateral lobe to the lesion (OR: 33.11, 95% CI: 4.22-192.28, p<0.001) and lesion size <= 25 mm (OR: 10.10, 95% CI: 3.54-75.01, p=0.001) were determined to contribute significantly to surgical failure. Conclusion The results of this study clearly showed that as residual tissue size <= 25mm and contralateral nerve damage in the preoperative ultrasonographic evaluation are associated with surgical failure, alternative treatment methods such as radioactive iodine ablation may be preferred in these patients.Öğe Fascioliasis presenting as colon cancer liver metastasis on 18F-fluorodeoxyglucose positron emission tomography/computed tomography: A case report(Baishideng Publishing Group Inc, 2019) Akbulut, Sami; Ozdemir, Egemen; Samdanci, Emine; Unsal, Selver; Harputluoglu, Murat; Yilmaz, SezaiBACKGROUND Fascioliasis is caused by watercress and similar freshwater plants or drinking water or beverages contaminated with metacercariae. Fascioliasis can radiologically mimic many primary or metastatic liver tumors. Herein, we aimed to present the treatment process of a patient with fascioliasis mimicking colon cancer liver metastasis. CASE SUMMARY A 35-year-old woman who underwent right hemicolectomy due to cecum cancer was referred to our clinic for management of colon cancer liver metastasis. Both computed tomography and 18F-fluorodeoxyglucose positron emission tomography revealed several tumoral lesions localized in the right lobe of the liver. After a 6-course FOLFOX (folinic acid, fluorouracil, oxaliplatin) and bevacizumab regimen, the hypermetabolic state on both liver and abdominal lymph nodes continued, and chemotherapy was extended to a 12-course regimen. The patient was referred to our institute when the liver lesions were detected to be larger on dynamic liver magnetic resonance imaging 6 weeks after completion of chemotherapy. Right hepatectomy was performed, and histopathological examination was compatible with fascioliasis. Fasciola hepatica lgG enzyme-linked immunosorbent assay was positive. The patient was administered two doses of triclabendazole (10 mg/kg/dose) 24 h apart. During the follow-up period, dilatation was detected in the common bile duct, and Fasciola parasites were extracted from the common bile duct by endoscopic retrograde cholangiopancreatography (ERCP). Triclabendazole was administered to the patient after ERCP. CONCLUSION Parasitic diseases, such as those caused by Fasciola hepatica, should be kept in mind in the differential diagnosis of primary or metastatic liver tumors, such as colorectal cancer liver metastasis, in patients living in endemic areas.Öğe Isolated Roux loop versus conventional pancreaticojejunostomy following pancreaticoduodenectomy(Edizioni Luigi Pozzi, 2022) Ozdemir, Egemen; Gokler, Cihan; Gunes, Orgun; Kaplan, Kuntay; Aydin, Mehmet Can; Sumer, Fatih; Kayaalp, CuneytAIM: This study aimed to examine the effects of isolated Roux loop (IP) versus conventional pancreaticojejunostomy (CP) techniques on the rate of postoperative pancreatic fistula and its severity. MATERIAL AND METHODS: This study included retrospectively collected data from 132 patients who underwent pancreaticoduodenectomy in a single institute. Collected data were compared between IP and CP groups. Postoperative pancreatic fistula and its grades were defined according to International Study Group on Pancreatic Fistula (ISGPF) definition. RESULTS: A total of 58 patients had IP and 74 patients had CP. Biochemical leak (IP 20.6% versus CP 14.9%, p=0.38) and grade B/C pancreatic fistula (IP 20.6% versus CP 32.4%, p=0.13) rates of both groups were similar. Durations of hospital stay and intensive care unit stay and 30-day mortality rates of the two groups were similar. CONCLUSION: Isolated Roux loop reconstruction following pancreaticoduodenectomy is not associated with a lower rate of pancreatic fistula but may contribute to reducing the severity of pancreatic fistula.Öğe A Novel Radiological Predictor for Postoperative Pancreatic Fistula After Stapled Distal Pancreatectomy(Sage Publications Inc, 2021) Bag, Yusuf Murat; Topel, Cagdas; Ozdemir, Egemen; Saglam, Kutay; Sumer, Fatih; Kayaalp, CuneytBackground Distal pancreatectomy (DP) is the main surgical treatment of benign and malignant lesions located in pancreatic body and tail. Postoperative pancreatic fistula (POPF) following DP is still a considerable cause of morbidity. Identification of risk factors for POPF after DP might provide some preventive applications. We aimed to evaluate the factors affecting POPF after DP and to present a new and easy radiological predictive factor. Materials and Methods Thirty-four patients underwent DP with stapler closure were included. Several risk factors for clinically relevant POPF (CR-POPF) were analyzed. Additionally, computed tomography findings of pancreatic thickness (PT), main pancreatic duct diameter (MPDD), and PT/MPDD ratio were evaluated for POPF. Results CR-POPF was observed in 10 patients (29.4%). Univariate and multivariate analyses showed that previous abdominal surgery and PT/MPDD ratio were predictive factors for CR-POPF after DP (P = 0.040, P = 0.034, respectively). The cutoff value for the PT/MPDD ratio was 8. Conclusion A PT/MPDD ratio greater than 8 (a wide pancreas with a narrow duct) is a significant predictive factor for CR-POPF following DP.
