Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them.

Input:Laparoscopic-assisted versus open resection of right-sided colonic cancer--a prospective randomized controlled trial.  This study aims to compare the perioperative outcomes and survival between laparoscopic-assisted right hemicolectomy (LARH) and open right hemicolectomy (ORH) for right-sided colon cancer. Between July 1996 and October 2005, 145 patients were randomized to receive LARH (n = 71) or ORH (n = 74). The median follow-up of living patients was 99.7 months. The demographic data of the two groups were similar. The time to resume diet (4 vs. 5 days, p = 0.045) and the hospital stay (7.8 vs. 10 days, p = 0.033) were significantly shorter in LARH group, but these benefits were at the expense of longer operating time (198 vs. 129 min, p = 0.002) and higher direct cost (USD8745 vs. USD6293, p < 0.001). The morbidity and mortality were comparable between the two groups. After curative resection, the probabilities of survival at 5 years of the LARH and ORH groups were 74.2% (SE 7.4%) and 75% (SE 7.1%), respectively. The probabilities of being disease free at 5 years were 82.3% (SE 6.9%) and 84.1% (SE 6.2%), respectively. Laparoscopic-assisted resection of right-sided colonic cancer has the advantage over open surgery in allowing earlier recovery. However this is at the expense of a longer operating time and higher direct cost (registration number: NCT00485316 ( http://www.clinicaltrials.gov )). Output:
{'conditions': 'Colorectal Carcinoma', 'interventions': 'Procedure: Laparoscopic assisted resection of colorectal carcinoma'}
