1.Progress in the management of obstructing cancer of the left colon
Chinese Journal of Digestive Surgery 2015;14(6):517-520
Obstructing colorectal cancer is one of the acute abdominal diseases which are common in clinical practice.The initial symptoms of 8.0%-33.9% patients with obstructing colorectal cancer are complete or incomplete acute colonic obstruction.Seventy percent of obstructing colorectal cancer located at the left colon.There are no standard treatment methods for obstructed left colonic carcinoma (OLCC).Previously,a staged procedure was recommended.With the improvement of the intestinal surgical techniques,one-stage resection and anastomosis including intraoperative colonic irrigation,subtotal colectomy,metal stents placement and transanal drainage tube placement were preferred by most of the surgeons.In addition,metal stents placement and transanal drainage tube placement can reduce bowel pressure,which creates the possibility for the treatment of malignant colorectal obstruction by laparoscopes.
2.Application of trans-areola approach for costicartilage harvesting.
Chinese Journal of Plastic Surgery 2016;32(1):45-48
OBJECTIVETo investigate the trans-areola approach for costicartilage harvesting in order to avoid the obvious scar resulted by traditional approach through chest incision.
METHODSFrom 2013, 7 cases who underwent rhinoplasty received costicartilage harvesting through trans-areola approach. The incision was designed along the lower interior edge of right areola. Then the dissection was performed to expose the 5th costicartilage. Then a costicartilage, 2 - 5 cm in length, was harvested. The incision was closed delicately. The suture was removed 7 days after operation.
RESULTSThe patients were followed up for 3 months to 2 years without hypertrophic scar and breast deformity. The scar was located in conceal location. The satisfactory rate was higher than that in patients with chest incision.
CONCLUSIONSThe scar resulted from trans-areola approach is comparatively conceal, compared with that at chest.

OBJECTIVE:
To explore and summarize the operation method and operation stage for cochlear implant with chronic suppurative otitis media, to provide the clinical reference for cochlear implant with chronic suppurative otitis media.
METHOD:
The clinical data of 6 cases of cochlear implant with chronic suppurative otitis media from Jun 2006 to Mar 2009 in our hospital was analyzed retrospectively. The operation stage. surgical skill, possible risk and prognosis was analyzed and summarized.
RESULT:
3 of 6 cases received single stage subtotal petrosectomy and cochlear implant. 3 of 6 cases received subtotal petrosectomy, they received staged cochlear implant 1 to 6 months later. No complications occurred, all of the cochlear implanted had good open set speech perception.
CONCLUSION
Staged operation was the first choice for cochlear implant with chronic suppurative otitis media. Single stage operation took potential risks, it should be done cautiously. The key points for the operation was the clearance of the pathological tissue totally, this required good surgical skill and operation instrument.

Objective To explore the feasibility and efficiency of laparoscopic surgery for the treatment of acute biliary pancreatitis (ABP) at early stage. Methods From January 2003 to June 2006, 18 patients with ABP received laparoscopic surgeries, including laparoscopic cholecystectomy (LC) in 3, LC combined with laparoscopic common bile duct exploration (LCBDE) in 9, LC combined with opening of the pancreatic capsule for drainage in 5, and LC combined with LCBDE and opening of the pancreatic capsule for drainage in 1. Results In all the patients, the laparoscopic operations were completed successfully without conversion to open surgery. The operation time was 100-150 min with a mean of (115.3?15.2) min. The stones in the bile duct were removed completely by LCBDE in 10 patients. No subcutaneous emphysema, hemorrhage, abdominal abscess or stenosis of the bile duct occurred in this series. The 18 patients were followed up for 4-40 months (mean, 28.5 months), during which 2 patients developed pancreatic pseudocyst. One of the patients was cured by internal drainage. In the other patient, the pseudocyst was absorbed spontaneously. No recurrence of pancreatitis or common bile duct stones was found. Conclusions Laparoscopic surgery is minimally invasive and effective for the treatment of ABP at early stage.

OBJECTIVE:To observe therapeutic efficacy and safety of Kouyanqing granules for chronic periodontitis and it effects on inflammatory cytokine. METHODS:110 patients with chronic periodontitis were divided into control group(55 cases)and observa-tion group(55 cases). Control group accepted the periodontal basic treatment as oral hygiene instruction,supragingival scaling,subgin-gival scaling and root planning. Observation group was additionally given Kouyanqing granules 20 g orally,twice a day,on the basis of control group. Both groups were treated for 4 weeks. Clinical efficacies of 2 groups were observed as well as the levels of plaque in-dex(PLI),gingival index(GI),probing depth(PD),clinical attachment level(CAL),IL-17,IL-21,and the occurrence of ADR. RE-SULTS:Both groups completed the treatment,and no patient lost to follow up. Total response rate of observation group was significant-ly higher than that of control group,with statistical significance(P<0.05). After treatment,the levels of PLI,GI,PD,CAL,IL-17 and IL-21 in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group, with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on routine treatment,Kouyanqing granules show significant therapeutic efficacy for chronic periodontitis, can significantly improve periodontal symptom and reduce inflammatory factor level,but do not increase the incidence of ADR.
