Objective To investigate the effectiveness of endoscopic low-temperature plasma radiofrequency ablation with acellular dermal matrix patch for chronic abdominal wall sinus by comparing with the traditional surgical method. Methods Retrospective analysis was made on the clinical data of 53 cases of chronic abdominal wall sinus between January 2006 and May 2012. Of 53 patients, 18 underwent endoscopic low-temperature plasma radiofrequency ablation with acellular dermal matrix patch (trial group), and 35 underwent traditional surgical treatment (control group). No significant difference was found in gender, age, etiology, disease duration, and location between 2 groups (P gt; 0.05). Results The blood loss during sinus clearance, postoperative hospitalization days, and sinus union time of the trial group were significantly better than those of the control group (P lt; 0.05), but no significant difference was found in the operative time for sinus clearance (t=0.28, P=0.78). No postoperative sinus bleeding or infection occurred in the trial group, but bleeding and infection in 5 and 3 cases of the control group respectively, showing significant differences between 2 groups (P lt; 0.05). The follow-up time was 4-18 months (mean, 12.4 months) in the trial group, and was 6-48 months (mean, 38.5 months) in the control group. No sinus recurrence was observed during follow-up. Conclusion Endoscopic low-temperature plasma radiofrequency ablation with acellular dermal matrix patch has the following advantages in treating chronic abdominal wall sinus: clear view, thorough cleaning of granulation necrosis tissues, less bleeding, faster sinus union, and shorter hospitalization days; however, further observations on the long-term effectiveness and the safety are required .
Objective To explore the value of laparoscopy combined with gastroscopy in treatment for gastric stromal tumors. Method The clinical data of 45 patients with gastric stromal tumors performed laparoscopy combined with gastroscopy resection from June 2008 to June 2012 in this hospital were analyzed retrospectively. Results Forty-five patients with gastric stromal tumors were successfully excised by laparoscopy combined with gastroscopy， and the tumors were completely resected and no residual tumor at the edge. The length of surgical incision was about 4-6 cm with an average of 5.1 cm. The mean operation time was 75 min. Postoperative recovery was smooth， no surgery-related comp-lications occurred. The mean hospital stay was 6.8 d. No recurrence or metastasis happened within the follow-up with an average of 16.5 months. The immunohistochemical examination results：43 cases of CD117 was positive， 32 cases of CD34 was positive， 28 cases of SMA was positive， 2 cases of Desmin was positive， 22 cases of S-100 was positive. Conclusions The treatment of gastric stromal tumors through laparoscopy combined with gastroscopy is safe and effective. The benefits include minimal invasiveness， shorter operation time， and rapid postoperative recovery. The laparoscopy combined with gastroscopy can make more precise resection range， and avoid residual tumor and resection of excessive normal gastric tissue.
Objective To compare the therapeutic efficacy between the mini-incision anterior cervical approach thyroidectomy and modified Miccoli endoscopy assisted thyroidectomy for thyroid benign tumor. Methods Clinical data of 80 patients with thyroid benign tumor treated in The First Affiliated Hospital of General Hospital of PLA from Jan.2010 to Jan. 2012 were retrospectively analyzed，and the 80 patients were divided into mini-incision anterior cervical approach thyroidectomy group （n=40） and modified Miccoli endoscopy assisted thyroidectomy group （n=40） according to operative type. The operative time，drainage volume of neck，cosmetic satisfaction score，duration of hospitalization，expense of hospitalization，and rates of postoperative complication of 2 groups were compared and analyzed. Results The operative time of mini-incision anterior cervical approach thyroidectomy group were significantly longer than that ofmodified Miccoli endoscopy assisted thyroidectomy group〔（95.5±20.3）min vs. （62.4±15.5）min，P＜0.05〕，but thecosmetic satisfaction score〔（3.5±0.2） score vs. （4.3±0.1） score〕and expense of hospitalization〔（5 814.6±1 262.3）yuan vs. （9 846.7±1 080.5） yuan〕were lower （P＜0.05）. There were no significant differences on the drainage volumeof neck after operation〔（28.6±5.5） mL vs. （22.2±4.5） mL〕and duration of hospitalization〔（4.5±1.5） d vs. （3.8±0.9） d〕between the 2 groups （P＞0.05）. There were 3 cases happened transient hoarseness in mini-incision anterior cervical approach thyroidectomy group （all recovered in 1 month after operation） and 1 case in modified Miccoli endoscopy assi-sted thyroidectomy group （recovered in 3 months after operation），and there were no significant difference on incidence of recurrent laryngeal nerve injury （P=0.608）. No other complications happened. Conclusions Modified Miccoli endoscopy assisted thyroidectomy has better cosmetic benefit than mini-incision anterior cervical approach thyroidectomy， but more expensive. The patients who have specific cosmetic demand or engage in special profession can choose modified Miccoli endoscopy assisted thyroidectomy.
