Short-and long-term results with Karydaki's technique for sacrococcygeal pilonidal diseaseIntroduction: Sacrococcygeal pilonidal cyst or sinus is a common condition in young people. There is still discussion about which of the many existing techniques is best suited to resolve this condition. Objective: To analyze the short-and long-term use of Karydaki's technique in our Hospital. Material and Methods: We analyzed prospective protocols from patients with pilonidal cyst with Karydaki's technique from June 2005 to August 2010. Clinical and telephonic follow-up was done to all patients and a satisfaction survey done to a random sample of the series. Results: We analyzed 62 patients with mean age of 24.5 years (15-45), being 33 men (53%). Cysts were previously relapsed in 20.9% of cases. The average hospital stay was 2.5 days (1-3). Early complications occurred in 14.3% of patients being the most common seroma in 8% and dehiscence in 6.4%. At a mean follow up of 38 months (12-62), relapse occurred in two patients (3.2%), one at 6 months and the other at 3 years, being resolved one by a new Karydaki's technique and the other with marsupialization. Among the group surveyed for satisfaction, 75% found the technique satisfactory or very satisfactory in terms of aesthetics and 95% would recommend this technique. Conclusions: Karydaki's operation achieves with a simple and aesthetic technic a low recurrence and morbidity and a complete recovery after 15 days in most patients.

Laparoscopic colorectal surgery in ChileThe development of laparoscopic colorectal surgery began 20 years ago; however it took several years before gaining its acceptance by the international surgical community. The fi rst report in Chile was published in 1995. However, were necessary many years, until the middle of this decade, to know the fi rst prospective series experiences. Out of these reports, no reliable data exist regarding the development of laparoscopic colorectal surgery in Chile, related to the number of centers performing laparoscopic colorectal surgery or the number of procedures performed. For record these data, a standardized questionnaire was send to colorectal chairmans of all hospitals that had reported to be developing laparoscopic colorectal surgery in our country. Ten of 15 hospitals responded to the survey. Most of the procedures performed were hemicolectomies, principally for cancer and diverticular disease. The average conversion rate was 7% and hospital stay was 5 days. Morbidity and mortality rates were 12% and 0.4% respectively. In the last year was seen an increase in the number of laparoscopic procedures in relation to the previous period. In conclusion, laparoscopic colorectal surgery is a recent technique in Chile, which is being implemented progressively, with good overall results.
