Dear readers,

Our journal has been included in the PubMed directory as "Ulus Cerrahi Derg" in 2015 due to your scientific contributions between 2014 and 2016, and has been accepted to the newly created Emerging Sources Citation Index (ESCI) within the Web of Science in 2016. In the PubMed directory, the visibility numbers of the articles published in our magazine increase day by day. Our ultimate goal is acceptance of the Turkish Journal of Surgery in the Science Citation Index (SCI) and the Science Citation Index Expanded (SCIE) directories. To reach this goal, it is important that you cite the articles published in our journal in the articles you submit to the journals included in the SCI and SCIE directories. With your support, we think our magazine can be accepted to these indices as of 2017.

Clinical and experimental studies of benefit are presented in this issue. The experimental research study examining the effect of melatonin on the repair of aresnic induced liver damage in rats is a good example of its category. Another study investigated the reasons for using animal studies in our country. In the studies on extralevator abdominoperineal excision in low rectum cancer and on pancreaticoduodenectomy in pancreatic cancer, the clinics share their experiences.

Clinical trials focusing on the factors affecting the results of laparoscopic sleeve gastrectomy in morbid obesity, a recently popular topic in laparoscopic surgery, and showing how to cope with complications will guide our colleagues. The survey on surgical emergencies in Konya province and the study on the awareness about mastitis in Samsun province delineate the situation in different regions of our country. Another study suggests a new system for the evaluation of observational studies that are sent to Congresses. The consensus reports on the management of biliary tract injuries during laparoscopic cholecystectomy and intraabdominal infections, as well as the editorial letter including a link to the Turkish version of American Thyroid Association's 2015 guideline will also be of interest to our colleagues.

Hoping to meet with better news in the upcoming issues.
