    (Istanbul Univ, Faculty Medicine, Publishing Office, 2018) Dural, Ahmet Cem; Kabuli, Hamid Ahmet; Unsal, Mustafa Gokhan; Baytekin, Halil Firat; Akarsu, Cevher; Başoğlu, İrfan; Mert, Meral; Inci, Ercan; Kocatas, Ali; Alis, Halil
    Adrenal neoplasms comprising more than one cell type and demonstrating a mixed histologic appearance are rare. A 57-year-old woman presented with a history of nausea, an increase in the frequency of urination, abdominal pain, and hypertension. Laboratory results revealed elevated urinary dopamine and metanephrine excretion in 24-h urine collection. A 50-mm right suprarenal mass was detected on computed tomography, which was hyperintense on T-2-weighted and heterogeneously isointense on T-1-weighted images on magnetic resonance imaging The patient underwent laparoscopic right adrenalectomy. Her perioperative period was uneventful. Histopathologic and immunohistochemical examination showed mixed medullary histologic characteristics for pheochromocytoma and ganglineuroma. Although the capsular and periadrenal adipose tissues were invaded by the tumor, the patient was disease and symptom free at the 5-year follow-up. Composite adrenal medullary tumors are rare, and benign tumors with a distant metastasis have been reported in one patient. Our case also showed a potential malignant behavior in terms of the capsular and periadrenal adipose tissue invasion. It can be concluded that such patients should undergo life-long clinical and biochemical follow-ups.

    Risk factors affecting benign anastomotic stricture in anterior and low anterior resections for colorectal cancer: a single-center retrospective cohort study
    (Springer, 2023) Surek, Ahmet; Donmez, Turgut; Gemici, Eyup; Dural, Ahmet Cem; Akarsu, Cevher; Kaya, Arif; Ferahman, Sina
    Purpose Although not as life-threatening as anastomotic leakage, anastomotic stricture reduces the quality of life. The risk factors for such an important life complication have not been revealed. This article examines the risk factors affecting anastomotic strictures due to colorectal cancers.Methods Patients who underwent anterior and low anterior resection for colorectal cancer under elective conditions between 2015 and 2021 were included in the study. The patients were divided into two groups, those who developed anastomotic stricture and those who did not. The parameters determined between the two groups were compared, and multivariate analysis of statistically significant parameters was performed.Results A total of 375 patients were included in the study. The anastomotic stricture was detected in 36 (9.6%) patients. In the multivariate analysis, non-mobilization of the splenic flexure and a proximal clean surgical margin of < 10 cm and a distal surgical margin of < 2 cm were identified as risk factors affecting anastomotic stricture. The risk factor with the highest odds ratio in the development of anastomotic stricture is the non-mobilization of the splenic flexure (p = 0.001, OR 11.375).ConclusionIt is recommended that the mobilization of the splenic flexure to reduce the development of strictures. In addition, a clean surgical margin of 10 cm proximally and 2 cm distally and high ligation of the inferior mesenteric artery may reduce the development of stricture.

    Risk factors for conversion in laparoscopic totally extraperitoneal inguinal hernioplasty
    (Wolters Kluwer, 2022) Karabulut, Mehmet; Dönmez, Turgut; Şahbaz, Nuri A.; Akarsu, Cevher; Ferahman, Sina; Sürek, Ahmet; Gemici, Eyüp; Aydın, Hüsnü; Sunamak, Oğuzhan; Dural, Ahmet Cem
    Background: Conversion is a surgical concern because the surgical technique can change during surgery. Surprisingly, there is no study in the literature on the causes and risk factors leading to conversion in laparoscopic total extraperitoneal inguinal repair (TEP). There is also no consensus on the prevention and causes of this condition in TEP. The aim of this study was to evaluate the risk factors underlying the development of conversion during TEP. Materials and Methods: We recruited 962 consecutive patients who underwent TEP between May 2016 and May 2021. All data were collected retrospectively. The outcomes of patients who converted to open surgery were compared with those without conversion. Multivariate analysis identified independent risk factors for conversion. Results: The overall incidence of conversion was 4.05% (n= 39). The median age was 42 years (18 to 83) and body mass index was 25.2 kg/m2 (15.67 to 32.9). Significant clinical factors associated with conversion included old age, American Society of Anesthesiologists (ASA) score, large peritoneal tear (PT), Charlson comorbidity index, previous surgery, large hernial defects, presence of scrotal hernia, and the defect size of inguinal hernia. Multivariate analysis identified independent risk factors for conversion: large hernial defect, large PT, previous lower abdominal surgery, previous hernia surgery, and scrotal hernia. Conclusion: Conversion is a minor complication seen during TEP and its incidence varies depending on many factors. Previous lower abdominal surgery and a large PT carries a 6-fold increased risk for conversion from laparoscopic to open surgery during TEP

    An unusual finding after adrenal surgery: a case series of adrenal schwannomas
    (Frontiers Media Sa, 2023) Kostek, Mehmet; Unlu, Mehmet Taner; Caliskan, Ozan; Aygun, Nurcihan; Iscan, Yalin; Dural, Ahmet Cem; Sormaz, Ismail Cem
    Adrenal schwannomas are rare benign tumors with no specific imaging and laboratory findings to diagnose preoperatively. Due to the limited number of cases in the literature, clinical, imaging, and pathological findings are presented in this study. Case 1 is a 61-year-old woman patient who has a 31-mm mass in the right adrenal gland. This mass was nonfunctional; in imaging studies, this mass had a cystic necrotic component, and high 18-fluorodeoxyglucose (FDG) uptake was seen. There was no metaiodobenzylguanidine (MIBG) uptake. Laparoscopic transabdominal right adrenalectomy was performed, and the pathology result was consistent with adrenal schwannomas. Case 2 is a 63-year-old man patient who presented with a 38-mm mass in the left adrenal gland. This mass was nonfunctional and similar to that in Case 1; this mass had a cystic component. Laparoscopic transabdominal left adrenalectomy was performed. The diagnosis of adrenal schwannoma with degeneration was revealed. Case 3 was a 72-year-old woman patient admitted to the hospital for a 125-mm left adrenal mass. Similar to Case 1, this mass also had a cystic necrotic component in imaging studies. High FDG uptake was seen, and the patient underwent conventional adrenalectomy due to the suspicion of malignancy. After pathological evaluation, a diagnosis of adrenal schwannoma was made. A main diagnostic challenge in adrenal schwannomas is the preoperative diagnosis. These masses have no pathognomonic finding or specific hormonal function. Imaging findings of these masses may increase the suspicion of malignancy, which may affect decisions for surgery and the surgical technique.
