    Colorectal cancer is the third most common cancer in Turkey. The current guidelines do not provide sufficient information to cover all aspects of the management of rectal cancer. Although treatment has been standardized in terms of the basic principles of neoadjuvant, surgical, and adjuvant therapy, uncertainties in the management of rectal cancer may lead to significant differences in clinical practice. In order to clarify these uncertainties, a consensus program was constructed with the participation of the physicians from the Acibadem Mehmet Ali Aydinlar and Koc Universities. This program included the physicians from the departments of general surgery, gastroenterology, pathology, radiology, nuclear medicine, medical oncology, radiation oncology, and medical genetics. The gray zones in the management of rectal cancer were determined by reviewing the evidence-based data and current guidelines before the meeting. Topics to be discussed consisted of diagnosis, staging, surgical treatment for the primary disease, use of neoadjuvant and adjuvant treatment, management of recurrent disease, screening, follow-up, and genetic counseling. All those topics were discussed under supervision of a presenter and a chair with active participation of related physicians. The consensus text was structured by centralizing the decisions based on the existing data.

    Totally Robotic Versus Totally Laparoscopic Surgery for Rectal Cancer
    (LIPPINCOTT WILLIAMS \& WILKINS, 2018-01-01) Esen, Eren; Aytac, Erman; Agcaoglu, Orhan; Zenger, Serkan; Balik, Emre; Baca, Bilgi; Hamzaoglu, Ismail; Karahasanoglu, Tayfun; Bugra, Dursun
    In this study, perioperative and short-term postoperative results of totally robotic versus totally laparoscopic rectal resections for cancer were investigated in a comparative manner by considering risk factors including obesity, male sex, and neoadjuvant treatment. In addition to overall comparison, the impact of sex, obesity (body mass index >= 30 kg/m(2)), and neoadjuvant treatment was assessed in patients who had a total mesorectal excision (TME). Operative time was longer in the robotic group (P<0.001). In obese patients who underwent TME, the mean length of hospital stay was shorter (7 +/- 2 vs. 9 +/- 4 d, P=0.01), and the mean number of retrieved lymph nodes was higher (30 +/- 19 vs. 23 +/- 10, P=0.02) in the robotic group. Totally robotic and totally laparoscopic surgery appears to be providing similar outcomes in patients undergoing rectal resections for cancer. Selective use of a robot may have a role for improving postoperative outcomes in some challenging cases including obese patients undergoing TME.

    Transvaginal Specimen Extraction in Minimally Invasive Colorectal Resections: Initial Experience of a Tertiary Referral Hospital
    (Acıbadem Mehmet Ali Aydınlar Üniversitesi, 2019-10-01) Bayraktar, Onur; Esen, Eren; Bengür, Fuat Barış; Erenler Bayraktar, İlknur; Aytaç, Erman; Bilgin, İsmail Ahmet; Baca, Bilgi; Güngör, Mete; Karahasanoğlu, Tayfun; Hamzaoğlu, İsmail
    ABSTRACT Purpose: The aim of the present (this) study is to present the initial experience of a single team on specimen extraction from the vagina after laparoscopic or robotic colorectal resections. Patients and methods: Between January 2010 and April 2015, ten female patients whose resection specimens had been extracted transvaginally after robotic or laparosopic colorectal resections were evaluated in terms of short and mid term postoperative outcomes. Results: 10 cases were included. The operations were robotic rectal resections for cancer (n=6), laparoscopic total colectomy for transverse colon tumor (n=1), single port laparoscopic transumbilical right colectomy for Crohn’s disease (n=1), laparoscopic rectal resection for endometriosis (n=2). In one patient, a vaginal bleeding occurred on postoperative day 7 and a vaginal tampon was inserted and the bleeding was stopped. One patient had a urinary tract infection, it was treated with proper antibiotic therapy. The median postoperative hospital stay was 5 (4-9) days. No mortality occurred. Conclusion: Transvaginal specimen extraction is feasible after colorectal resection and could prevent additional skin incision and its potential complications.
