    Are there any differences between age groups regarding colorectal surgery in elderly patients?
    (2014) Bircan, Huseyin Yuce; Koc, Bora; Ozcelik, Umit; Adas, Gokhan; Karahan, Servet; Demirag, Alp
    Background: Surgical procedures with curative or palliative intentions in subjects aged over 70 represent a colorectal surgical challenge due to the issue they raise: Benefits versus increased morbidity. In this study, we proposed to compare the impact of surgery with the surgical intervention short-term results and analyze the factors that may influence these results in elderly age groups. Methods: We retrospectively analyzed a database containing information about patients who underwent colorectal surgery from January 2008 to December 2013 at the Baskent University Istanbul Research Hospital and the Okmeydani Training and Research Hospital. Results: A total of 265 patients were enrolled and analyzed in this retrospective study. Of these patients operated during the study period, 110 were between 60 and 69 years of age (group 1), 99 were between 70 and 79 years of age and 56 were older than 80 years of age. In total, there were 138 (52%) men and 127 (48%) women that underwent colorectal surgery. Intraoperative complications did not differ between group 1 and group 2, group 2 and group 3; however, some differences were observed between group 1 and group 3 (p = 0.001). Systemic complications were more frequent in group 3 than in groups 1 (p = 0.039) and 2 (p = 0.002). Furthermore, there were no significant systemic complication differences between groups 1 and 2. The mean length of postoperative hospital stay was 9.91 +/- 2.65 days in the first group, 9.38 +/- 2.44 days in the second group and 11.8 +/- 4.35 days in the third group. Conclusion: Colon surgery for both malignant and non-malignant diseases can be performed safely in different elderly age groups; thus, age should not be considered as an obstacle in elderly patients undergoing colorectal resection.

    Rectal diverticulitis mimicking rectal carcinoma with intestinal obstruction: Case report
    (2015) Ozcelik, Umit; Bircan, Huseyin Yuce; Eren, Eryiğit; Demiralay, Ebru; Isiklar, Iclal; Demirag, Alp; Moray, Gokhan; 25698274
    Although diverticular disease of the colon is common, the occurrence of rectal diverticula is extremely rare with only sporadic reports in the literature since 1911. Symptomatic rectal diverticula are seen even less frequently, and surgical intervention is needed for only complicated cases. Here we report the case of a 63-year-old woman presenting with rectal diverticulitis mimicking rectal carcinoma with intestinal obstruction.

    Effect of Topical Platelet-Rich Plasma on Burn Healing After Partial-Thickness Burn Injury
    (2016) Ozcelik, Umit; Ekici, Yahya; Bircan, Huseyin Yuce; Aydogan, Cem; Turkoglu, Suna; Ozen, Ozlem; Moray, Gokhan; Haberal, Mehmet; 27262706
    Background: To investigate the effects of platelet-rich plasma on tissue maturation and burn healing in an experimental partial-thickness burn injury model. Material/Methods: Thirty Wistar albino rats were divided into 3 groups of 10 rats each. Group 1 (platelet-rich plasma group) was exposed to burn injury and topical platelet-rich plasma was applied. Group 2 (control group) was exposed to burn injury only. Group 3 (blood donor group) was used as blood donors for platelet-rich plasma. The rats were killed on the seventh day after burn injury. Tissue hydroxyproline levels were measured and histopathologic changes were examined. Results: Hydroxyproline levels were significantly higher in the platelet-rich plasma group than in the control group (P=.03). Histopathologically, there was significantly less inflammatory cell infiltration (P=.005) and there were no statistically significant differences between groups in fibroblast development, collagen production, vessel proliferations, or epithelization. Conclusions: Platelet-rich plasma seems to partially improve burn healing in this experimental burn injury model. As an initial conclusion, it appears that platelet-rich plasma can be used in humans, although further studies should be performed with this type of treatment.
