Objective To investigate the clinical characteristics of clavicular defect and nonunion after operation and evaluate the clinical effects of vascularized pedicled pectoralis major clavicular periosteal flap and locking plate fixation plus bone morphogenetic protein (BMP) implantation. Methods From January 2004 to April 2008, 12 patients (mean age, 42.8 years old) with clavicular defect and nonunion were treated in Zhongshan Hospital. The internal fixators were removed, and then fibrous scars and sclerotic bones were cleared. The clavicular detects were fixed with locking plate, with implantation of the BMP. The wound was covered with vascularized pedicled pectoralis major clavicular periosteal flap. Postoperative functional rehabilitation exercises were performed. Results All patients were followed up for 8-24 months (mean 1.2 years). The clinical results were evaluated by Constant-Murley scoring system. The clavicular defects were healed in all patients within 4-7 months, and the internal fixators were successfully removed from some of the patients. Conclusions Vascularized pedicled pectoralis major clavicular periosteal flap combined with locking plate fixation plus BMP implantation is effective in the treatment of clavicular defect and nonunion.

Objective To analyze the clinical effects, as well as its advantages and disadvantages, of laparoscopic surgery for appendicitis in obese patients. Methods Clinical data of 80 obese patients receiving appendectomy, including 38 cases of open appendectomy and 42 cases of laparoscopic appendectomy, were analyzed retrospectively.The operative time, blood loss, analgesic and antibiotic use, postoperative fever, postoperative complications, length of hospital stay, and hospitalization cost were compared between the two operative methods. Results Conversions to open surgery were required in 2 patients in the laparoscopic group. There was no significant difference in operative time between the 2 groups (P >0.05).Compared with the open group, the laparoscopic group had less blood loss [(14.98 ±12.77) ml vs.(31.58 ±19.00) ml, t=-4.550, P=0.000], shorter time of postoperative antibiotic use [(2.7 ±1.0) d vs.(4.1 ±1.2) d, t=-5.470, P=0.000], less postoperative analgesics needed [5.0%(2/40) vs.26.3%(10/38),χ2 =6.802, P=0.009], less drainage [2.5% (1/40) vs.18.4% (7/38), χ2 =5.367, P=0.021], less postoperative fever [5.0%(2/40) vs.23.7%(9/38),χ2 =5.616, P=0.018], less postoperative wound healing [5.0%(2/40) vs.21.1%(8/38),χ2 =4.493, P=0.034], and shorter hospital stay [(5.9 ±3.2) d vs.(8.7 ±4.1) d, t=-3.345, P=0.001], but the higher cost of hospitalization [(7800 ±396) yuan vs.(4914 ±434) yuan, t=30.716, P=0.000]. Conclusion For obese patients with appendicitis, laparoscopic appendectomy has less surgical trauma, faster recovery, less postoperative pain, fewer complications,and shorter hospital stay, being a preferred method of treatment.

Objective: To study the pathological characteristics of columnar alteration with prominent snouts and secretions (CAPSS) and its relationship with incidence of breast carcinoma. Methods: One hundred forty-four CAPSS specimens identified by breast core needle biopsies(CNB) were retrospectively evaluated. The CAPSS specimens were subdivided into lesions with (n=108) and without (n=36) atypical ductal hyperplasia and their pathological findings were compared. Results: In situ and invasive carcinomas were found in 21.5% (31/144) of the specimens, including those with and without atypical hyperplasia. We also found that specimens with atypical hyperplasia had a higher malignant incidence than those without atypical hyperplasia (P=0.001). Conclusion: CAPSS, especially when with atypical ductal hyperplasia, are associated with breast carcinoma.

Methods:Twenty-five patients could not have oral intake due to obstruction of the oesophagus and depended on long-term parenteral nutrition.They contraindicated for percutaneous endoscopic gastrostomy.Results:The procedures all were successful completed without complication.The patients could use home enteral nutrition and get rid of parenteral nutrition.The patients' quality of life was improved significantly.Conclusion:PFG is a useful,convenient and less complication method for patients who are contraindication for PEG.

Objective To study the effect of mini percutaneous nephrolithotripsy (MPCNL) for non-nephredema kidney calculi. Methods A total of 47 patients with non-nephredema kidney calculi were enrolled in this study. Physiological saline solution was infused into the kidney through a ureteral catheter to induce hydronephrosis. C-arm X-ray machine was employed in percutaneous puncture and Wolf EMS was used to smash the calculi. Results The mean operation time was (120?35) min.The calculi were removed through one passage in 38 cases,through two passages in 6, and three passages in 3. Among the 47 patients, the MPCNL was performed once in 35, and twice in 12. The stone-free rate was 83.0% (39/47) and final stone-free rate was 93.6% (44/47). No complications were noted in all the patients. Conclusions Highly skilled technique is necessary in MPCNL for non-nephredema kidney calculi. The MPCNL is a safe, minimally invasive, and effective method. By using MPCNL, patients have less trauma, lower rate of calculi remaining, and quick recovery. As long as the surgeons are familiar with the technique of MPCNL and the anatomy of non-nephredema kidney, the therapeutic outcome can be as good as that in the patients with nephredema renal calculi.

Objective:To study the CT and PET/CT features of pleural mesothelioma and the value of CT and PET/CT imaging in the diagnosis of the disease.Methods:We retrospectively analyzed the spiral CT images of 23 patients and PET/CT images of 7 patients with pleural mesothelioma,all histologically confirmed.Results:Of the 23 cases detected by spiral CT,7 were benign and 16 malignant;local nodular pleural thickening was found in 9 cases,7 benign and 2 malignant;diffuse pleural thickening was observed in 14 cases,all malignant.Of the 7 cases diagnosed by PET/CT,5 were excluded from surgery.Conclusion:CT imaging helps determine the location,shape,extent of the pleural lesion and its relation to the surrounding tissues,while PET/CT is better in the differentiation of pleural mesothelioma and staging of malignancy,and therefore plays an important guiding role in the treatment of the disease.
