This paper describes some new concepts and new technologies about the current colorectal surgery, such as minimally invasive, bloodless surgery, no touch technique, and some new techniques of gastrointestinal anastomosis. Meantime, bloodless technique and closed resection in our clinic practice are introduced. These new concepts and new techniques widely used improve significantly the efficacy of colorectal surgery.

This paper introduces a new search strategy on the basis of self-adaption step, aiming at solving the problem that primary double iron rotating electro-magnetic tracking method can not make a good balance of accuracy and efficiency. Through the emulation, we can conclude that this new strategy can sharply increase the efficiency, with the accuracy identical to that of the fixed-step (0.5 degrees).

OBJECTIVETo give a conceptual description of natural orifice translumenal endoscopic surgery (NOTES), review the early efforts in the NOTES field, and discuss its challenges and limitations.

DATA SOURCESThe data were retrieved mainly from publications listed in MEDLINE, PubMed and China Wanfang Database from 2005 to 2009. The search term was "NOTES".

STUDY SELECTIONThe articles involved in the "NOTES" study were selected and the review articles were excluded from the comparison.

RESULTSA marked increase in quantity in articles was shown each year for NOTES studies from 2006 to 2009. Animal experiments with "NOTES" have been carried out in China from 2007, and two independent "NOTES" procedures on humans were reported in 2009.

CONCLUSIONAlthough still in its infancy, the "NOTES" procedure is promising as another type of minimally invasive surgery and favorable alternative to current interventions.

OBJECTIVETo systematically review the effectiveness of minimally invasive total hip arthroplasty (MIS-THA) versus traditional total hip arthroplasty (THA) in patients with hip diseases.

METHODSThrough a method of combining Free words and keywords,we searched databases including PubMed,The Cochrane Library, EMbase,Web of Science, CBM , CNKI and Wanfang Data for randomized controlled trials (RCTs) on the comparison between MIS-THA and THA for hip disease from inception to June, 2014. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, extracted data and assessed the quality of the included studies according to the "bias risk assessment" tool recommended by Cochrane Handbook 5.0 for Systematic Reviews. Then, meta-analysis was performed using RevMan 5.3 software.

RESULTSThirteen RCTs involving 1 213 cases of surgeries and total 1 284 hips (MIS-THA: n = 631; THA: n = 653) were identified. The results of meta-analysis showed that statistically significant differences were found in Harris hip score on the 3rd month after operation [MD = 8.37, 95% CI (6.02,10.72)], Hematocrit [MD = 0.02, 95% CI (0.01, 0.03)] and Hemoglobin [MD = 0.50, 95% CI (0.16, 0.85)] at the 48th hour after operation, changed value of femoral offset [MD = 0.30, 95% CI (0.04, 0.56)] between two groups. In the change value of femoral offset, THA was better than MIS-THA; There were no statistically significant differences between two groups in Harris hip score at 1st year after operation [MD = 3.26, 95% CI (-3.25, 9.76)], WOMAC score [MD = -0.53, 95% CI (-3.67, 2.60)] and Oxford score [MD = 1.34, 95% CI (-3.46, 6.13)] at the 6th week after operation, Hematocrit at the 8th hour after operation [MD = -0.01, 95% CI (-0.02, 0.00)], the incidence of hip varus [RR = 0.82, 95% CI (0.45,1.52)] and dislocation [RR = 1.40, 95% CI (0.48, 4.12)].

CONCLUSIONTHA brings less trauma, less hemorrhage and better early clinical outcome compared with MIS-THA, but the difference of the complication rates between the two groups is similar.
