Objective To evaluate the effect of endoscopic surgery combined with intraoperative color Doppler ultrasound on removing the injected breast augmentation agents and share our experiences. Methods Sixteen female who accepted the bilateral removal of injected breast augmentation agents through endoscopic surgery combined with intraoperative color Doppler ultrasound between 2008 and 2010 were enrolled in this study. The results, techniques, and advantages of management were analyzed retrospectively. Results One incision was made in 18 breasts, 2 in 4 breasts, 3 in 10 breasts. The length of incision was 0.5 to 1 cm. The mean operative time was 128.70 min per person. The average amount of bleeding was 52.67 ml per person. Complications such as postoperative bleeding, infection, poor drainage, or breast augmentation agents remain did not happened in all cases. No case was turned into normal operation. Female who accepted this operation were all satisfied with the appearance of incisions. During 1-3 months follow up, neither clinically palpable mass nor sensory disturbance in nipple or areola of breast was observed. Color Doppler ultrasound or magnetic resonance showed 16 cases had been cleared free of breast augmentation agents. Conclusion With the advantages of beauty, safe, minimal invasion, and partial resection of lesions at the same time, endoscopic surgery combined with intraoperative color Doppler ultrasound was an effective approach in the removal of injected breast augmentation agents.
ObjectiveTo explore the curative effect of precise hepatectomy techniques in hepatolithus. MethodsTotally 132 patients underwent precise hepatectomy and 52 patients underwent irregular hepatectomy were retrospectively analyzed, and the intraoperative and postoperative indexes such as operation time, blood loss, postoperative complications, hospitalization time, clearance rate of calculus, and cost of hospitalization were analyzed. ResultsCompared with the patients in irregular hepatectomy group, although the operative time was longer in precise hepatectomy group 〔(364.6±57.8) min vs. (292.9±44.7) min, Plt;0.001〕, but the patients in precise hepatectomy group had less blood loss 〔(558.3±90.6) ml vs. (726.7±88.7) ml, Plt;0.001〕, less postoperative complications (11.4% vs. 23.1%，P=0.004 3), and higher clearance rate of calculus (89.4% vs. 73.1%, P=0.005 5). Thus, the patients in precise hepatectomy group had shorter hospital stay 〔(22.9±4.4) d vs. (28.8±3.5) d, Plt;0.001〕 and less cost of hospitalization 〔(1.8±0.7)×104 yuan vs. (2.1±0.9)×104 yuan, P=0.016 5〕. Conclusion Precise hepatectomy is better than irregular hepatectomy in treatment for hepatolithus.
ObjectiveTo assess the feasibility of the treatment of unresectable late pancreatic cancer with laparoscopic choledochojejunostomy and gastric bypass. MethodsFrom June 2000 to December 2003, laparoscopic choledochojejunostomy and gastric bypass were successfully performed in 15 patients with unresectable late pancreatic cancer. Endoscopic nosobiliary drainage (ENBD) was performed before the operation. ResultsAll procedures were completed laparoscopically. Jaundice and hepatic function of the patients were obviously improved after the bypass. Oral nutrition was recovered after operation. The mean operative time was (100±26) min (range 70-200 min); the mean operative blood loss was (60±15) ml (range 30-120 ml); the bowel function recovery was on the 3rd-5th postoperative day; the average hospital stay was (8.1±0.7) days (range 6-13 days). Incision infection ocurred in one patient. No operative complications occurred in other patients. ConclusionTreatment of unresectable late carcinoma of the pancreas with laparoscopic choledochojejunostomy and gastric bypass aided by ENBD is a minimally invasive technique with less postoperative pain，shorter hospital stay, lower procedurerelated morbidity,and better oral nutrition. The life quality of patients with late pancreatic cancer can be obviously improved.
Objective To assess the feasibility and adequacy of Harmonic Scalpel in a totally laparoscopic total mesorectal excision (TME) and low,ultralow,colo-anal anastomoses for rectal cancer. Methods Excision of the mesorectum and low，ultralow site anastomoses were performed laparoscopically on 30 patients with low rectal cancer based on the concept of TME. Results All 30 TME were successfully completed by laparoscopic approach, and no one was converted to open procedures. A cholecystectomy and/or an ovariotomy were meanwhile performed laparoscopically for 3 patients with rectal cancer,and 1 patient with chronic cholesyctitis, gallstone,ovarian cyst and torsion of the ovary. The operation time was 155 min (115-320 min). Operative blood loss was 20 ml (5-80 ml).The time of bowel function returned and the time to resume postoperative diet was 1-2 days after the operation. Fourteen patients had postoperative analgesic requirement. Average hospital stay was 8 days (5-14 days) and there were no intraoperative and postoperative complications in all 30 patients.Conclusion Laparoscopic excision of the mesorectum and low,ultralow,coloanal anastomoses with Harmonic Scalpel for low rectal cancer is a perspective minimally invasive technique, which is feasible, safe, effective and has dramatic high rates of sphincter preservation with decreased postoperative pain, rapid recovery.

Objective To summarize diagnosis and treatment outcomes of coronary arterial fistulas （CAFs） so as to improve surgical results. Methods Clinical data of 23 patients with CAFs who underwent surgical repair in Xinhua Hospital，School of Medicine，Shanghai Jiaotong University from July 2006 to January 2013 were retrospectively analyzed. There were 15 male and 8 female patients with their age of 35.4±8.7 years. CAFs originated from left anterior descendingartery in 7 patients，right coronary artery in 13 patients，dual coronary arteries in 1 patient，left main coronary artery in 1 patient，and obtuse marginal artery in 1 patient. CAFs drained into pulmonary artery in 16 patients，right ventricle in 5patients，and right atrium in 2 patients. Twelve patients received surgical repair under off-pump condition with beating heart，and the other 11 patients underwent surgery under cardiopulmonary bypass （CPB）. Surgical techniques included extracardiacgasket interrupted suture ligation，intracardiac mattress suture ligation，intracardiac gasket interrupted suture for fistula repair，and a combination of intracardiac suture ligation and extracardiac repair. Results There was no in-hospital death or seriouspostoperative complication in this group. For the 11 patients undergoing surgical repair under CPB，average CPB time was 78.6±7.4 minutes，and average aortic cross-clamping time was 39.0±5.9 minutes. Postoperatively，patients’ heart functionrecovered well，their symptoms disappeared，and there was no myocardial ischemia or residual fistula. Twelve patients werefollowed up at the outpatient department and via telephone for 3 months to 6 years after discharge. During follow-up，theirheart function all recovered well，and echocardiogram detected no abnormality. There was no late death，myocardial ischemiaor residual fistula. Conclusion All CAFs patients need early surgical repair once their diagnosis is clear. Appropriate surgical strategies should be chosen according to the characteristics of pathological anatomy and associated intracardiaclesions. Surgical outcomes are satisfactory.
Objective To explore the feasibility，safety and clinical applicability of combined complete thoracoscopicand laparoscopic esophagectomy for the treatment of esophageal carcinoma. Methods Clinical data of 34 patients with esophageal carcinoma who underwent combined complete thoracoscopic and laparoscopic esophagectomy in the Departmentof Thoracic Surgery of our hospital from January 2012 to June 2013 were analyzed retrospectively. There were 33 males and1 female with their age of 63 （41-76） years. Results One patient received conversion to laparotomy and 1 patient diedpostoperatively. Mean operation time was 362.1 （300-560） minutes，including 90.6 （60-220） minutes for thoracoscopicprocedure in 34 patients and 61.1 （45-85） minutes for laparoscopic procedure in 33 patients. Mean intraoperative blood loss was 206.5 （100-500） ml. Average number of dissected lymph nodes was 18.0 （13-31） for each patient with positivemetastatic rate of 44.1% （15/34）. Postoperative pathological diagnosis was squamous cell carcinoma in 33 patients and smallcell carcinoma in 1 patient. Postoperative pathological staging was stageⅠB in 1 patient，stageⅡA in 1 patient，stageⅡB in 15 patients，stageⅢA in 11 patients，stageⅢB in 3 patients and stageⅢC in 3 patients. Postoperative hospital stay was 15.2 （6-35） days. Two patients received bedside bronchoscopic sputum suction. Postoperative complications occurred in32.4% （11/34） of all patients，including pulmonary infection in 4 patients （11.8%），respiratory failure in 2 patients （5.9%），chylothorax in 1 patient （2.9%），cervical anastomotic leak in 4 patients （11.8%） and hoarseness in 2 patients （5.9%）. We followed up 33 patients for 1-16 months. Two died，Two were lost. The other 29 patients survived. Conclusion Combined complete thoracoscopic and laparoscopic esophagectomy is a minimally invasive，feasible and safe surgical procedure for the treatment of esophageal carcinoma with quick postoperative recovery，and is worthy of furtherclinical application.
Abstract： Objective To study thoracic bone remodeling and clinical effects after minimally invasive correctionfor pectus excavatum （PE） in children. Methods A retrospective review was conducted of a prospectively gathereddatabase of 74 child patients who underwent minimally invasive repair of PE at General Hospital of Beijing MilitaryDistrict between Apr. 2009 and Sept. 2010. Of the patients, 63 were males and 11 females; the age was（ 11.90±8.50）years, 11 patients ＜ 10-year-old among them. Under general anesthesia, two incisions were made at the side midaxillaryline, and the introducer created a tunnel at the trans-substernum and shaped the thoracic cavity. The bar was then insertedinto the retrosternum by video-assistant thoracoscopic monitoring. All patients were checked by chest computerizedtomography（CT） scan preoperatively and one week after operation, with three-dimensional reconstruction. The sagittalview was by means of the center line of the body of thoracic vertebrae. The distance between the sternum and the frontaledge of the body of thoracic vertebrae was measured and the return of displacement of the heart was observed. ResultsAll 74 operations were successful; there were no deaths. One bar was used for 66 patients （89.19%）, while two barswere used for the other 8 patients （10.81%）. Comparing the results of pre- with post-correction, for patients youngerthan 10 years（n=11） who had one bar placed, the inferior extremity of the manubrium and midsternum displacedforward to 3.76-22.92 mm. For 11-17 year-old patients（n=55） , anterior displacement of only the middle and lowerpart of the midsternum was 2.08-10.42 mm. There was a significant difference between the two groups in the inferiorextremity of the midsternum displaced（t=14.24, P ＜ 0.05）. For those patients with two bars, the inferior extremity ofthe manubrium and the midsternum were each displaced forward 4.19-15.03 mm at 7 d after operation. At 7 d after operation,the cardiac position in 65 patients（ 87.84%） of the all putted back by CT image. The chest shape of patients who received twobars was better than that of patients who received one bar. After 6-23 months of follow-up, it was pre-operative symptomsdisappeared in the patients, chest shape was satiation. Cardiac position in all patients was completely recovered. ConclusionThe thoracic bones of children with PE after minimally invasive repair have favorable remodeling. Older children requiregreater strength of support of the sternum during correction, but still realize a satisfactory therapeutic effect.
Abstract: Objective To evaluate the feasibility and safety of combined laparoscopic and thoracoscopic esophagectomy and intrathoracic esophagogastric anastomosis for the treatment of esophageal cancer. Methods We retrospectively analyzed clinical data of 40 patients with esophageal cancer who underwent esophagectomy in Beijing Chaoyang Hospital of Capital Medical University from March 2010 to March 2012. All the 40 patients were divided into 2 groups according to their different surgical approach， including 22 patients who underwent combined laparoscopic and thoracoscopic esophagectomy and intrathoracic esophagogastric anastomosis （minimally invasive surgery group） and 18 patients who underwent Ivor Lewis esophagectomy （open surgery group）. Operation time， intra-operative blood loss， lymph node dissection， postoperative morbidity， hospital stay and cost were compared between the two groups. Results The hospitalcost of minimally invasive surgery group was significantly higher than that of open surgery group ［（78 181.5±8 958.8） yuan vs. （61 717.2±35 159.4） yuan， Z=4.078，P=0.000］ . There was no statistical difference in operation time ［（292.0±74.8） min vs. （256.1±41.0） min， t=1.838，P=0.074］， intra-operative blood loss ［（447.7±597.0） ml vs. （305.6±125.9） ml， Z=0.401，P=0.688］， total number of dissected lymph nodes （230 vs. 215， t=1.714，P=0.095）， postoperative morbidity ［22.7% （5/22） vs. 33.3% （6/18）， χ2=0.559，P=0.498］， time to resume oral intake ［（8.5±3.5） d vs. （11.1±9.6） d，t=1.202，P=0.237］， and postoperative hospital stay ［（11.6±5.7） d vs. （13.3±9.4） d， t=0.680， P=0.501）］ between the two groups. The minimally invasive surgery group was further divided into two subgroups according to operation date， including 10 patients in the early stage subgroup and 12 patients in the later stage subgroup. The operation time of the later stage subgroup was significantly shorter than that of the early stage subgroup ［（262.9±64.9） min vs. （327.5±73.0） min， t=2.197， P=0.040］， but not statistically different from that of the open surgery group ［（262.9±64.9） min vs. （256.1 ±41.0） min， t=0.353， P=0.727］. Intra-operative blood loss of the later stage subgroup was significantly reduced compared with those of the early stage subgroup ［（220.8±149.9） ml vs. （720.0±808.0） ml， Z=3.279， P=0.001)］ and the open surgery group ［（220.8±149.9）ml vs. （305.6±125.9） ml， Z=2.089， P=0.037）］. Conclusion Combined laparoscopic and thoracoscopic esophagectomy and intrathoracic esophagogastric anastomosis is a safe and effective surgical procedure for the treatment of esophageal cancer.
Abstract： Objective To explore a new videoassisted thoracoscopic surgical treatment for lone atrial fibrillation, in order to seek better efficacy, reduce invasiveness, and devise an easiertooperate surgical treatment for atrial fibrillation. Methods In June 2011, 3 women aged 40 years, 60 years, and 66 years with lone atrial fibrillation were treated in the Cardiovascular Surgery Department of West China Hospital. The patients underwent a videoassisted thoracoscopic “Box Lesion” bipolar radiofrequency atrial fibrillation therapy (bilateral pulmonary vein + left atrial posterior wall isolation), including three 5 to 10 mm small incisions on each side of the chest wall. The complications and sinus rhythm maintenance of the patients were observed. Results The operative times were 140 min, 170 min, and 155 min. The three patients were in sinus rhythm immediately after the surgery. Mean blood loss was approximately 80 ml, mean intensive care unit (ICU) stay was 1 day, and average hospital stay was 7 days. No deaths and serious complications occurred. The three patients were still in sinus rhythm one week and one month after the operation, as measured by electrocardiogram. Conclusion Box Lesion bipolar radiofrequency treatment for atrial fibrillation therapy shows fast postoperative recovery. It is a promising procedure in atrial fibrillation treatment and is worthy of further study.
