    (2019) Tolan, Huseyin Kerem; Canbak, Tolga
    Aim: The objective of this study was to evaluate treatment and postoperative recurrence in patients with neuroendocrine tumors of the appendix detected.Material and Methods: Patients with neuroendocrine tumors of the appendix detected between January 2015 and January 2016 were evaluated retrospectively. Patients who underwent incidental appendectomy due to different malignancies were excluded from the study. Results: A total of 402 patients who underwent appendectomy were evaluated. Five patients with neuroendocrine tumors detected, were included in the study. The mean age was 30.1 years. There were tumors in the apex, while a second tumor was found in the corpus in one patient. The mean tumor diameter was 0.6 cm. Ki-67 was under 2% in all patients. One patient underwent right hemicolectomy in the postoperative first month due to the infiltration to the periappendiceal tissue. The mean duration of hospitalization was 2 days. The mean duration of follow-up was 38 months (range 12- 54) . Ga 68 PET CT was taken in all patients after the histopathological examination. Control of the patients was performed after the first year with thorax and abdominal CT. None of the patients developed tumor. Conclusion: In general, clinical course is good and appendectomy is curative. However, right hemicolectomy is needed in patients with poor prognostic factors. Keywords: Incidental neuroendocrine tumor; appendectomy; general surgery.

    Timing of cholecystectomy in the treatment of mild acute biliary pancreatitis
    (2020) Acar, Aylin; Canbak, Tolga; Tolan, Huseyin Kerem
    Aim: In this study, we aimed to compare the results of emergency and elective cholecystectomy in patients admitted due to acute biliary pancreatitis.Material and Methods: A total of 632 patients admitted due to acute biliary pancreatitis were retrospectively evalauted. Patients with Ranson ≥ 3 and hour 48 CRP > 15 were considered as severe pancreatitis and excluded from the study. Patients were divided into two groups. Group 1 consisted of the patients who underwent emergency cholecystectomy after 48 hours, while Group 2 included the patients who underwent interval cholecystectomy. Results: A total of 386 patients were enrolled in the study. Group 1 consisted of 214 patients. The mean Ranson score was found as 1.3±0.9 in Group 1 and 0.92±0.7 in Group 2. A total of 148 patients in Group 1 and 117 patients in Group 2 had comorbidity (p=0.81). Conversion was performed in 8 patients in Group 1 and 5 patients in Group 2 (p = 0.78). Bile duct injury was not detected in either group. Among the patients in the interval cholecystectomy group, 7 patients were admitted to the hospital due to acute pancreatitits and total 13 patients due to biliopancreatic reasons during the interval period. Conclusion: No effect of cholecystectomy timing was detected on the conversion rates and development of complications. However, development of recurrence and related complications in the waiting period of the patients could be prevented by performing early cholecystectomy.
