Totally, 153 obese patients who underwent EVH （n=81） or standard bridging technique （SBT, n=72） in CABG surgery from May 2012 to October 2014 in our hospital were enrolled in this retrospective non-randomized controlled study. The general situation of operation, postoperative complications and short medium-term outcomes were analyzed. The baseline characteristics were similar between these two groups （P〉0.05）. There were no statistical differences in total operation time （226±28 min vs. 224±30 min, P〉0.05）, number of damaged vessels （0.12±0.05 vs. 0.16±0.06, P〉0.05） and short medium-term outcomes including revascularization rate （1.25% vs. 2.78%, P〉0.05）, vessel dysfunction rate （11.25% vs. 11.11%, P〉0.05） and mortality （0.00% vs. 0.00%, P〉0.05）. Use of EVH was associated with significant reduction of total harvesting time （41±6 min vs. 63±11 min, P〈0.05）, incision length （4.4±1.1 cm vs. 18.2±4.5 cm, P〈0.05） and postoperative lower extremity complications （P〈0.05）. EVH can reduce the risk of wound complications, whereas does not influence short- and medium-term outcomes in obese patients. It can be considered a reliable procedure of harvesting vessel conduits for obese patients undergoing CABG.展开更多

To achieve a complete revascularization, percutaneous coronary interventions （PCI） with drug eluting stent implantation to other coronary arteries was used. We reported outcomes of the treatment of multivessel coronary artery disease with minimally invasive coronary artery bypass （MICAB） and PCI. Methods Between January 2009 and Dec 2012, 14 patients （11 males, 3 females, mean age was 64.8 _ 10.1 years. Two-vessel disease account for 35.7% （5/14） of these patients, three-vessel disease 64.2% （9/14） （Table 1）. All patients underwent a minimally invasive coronary artery bypass grafting via mini-sternotomy ＂J＂ shaped approach. Seven patients were followed by PCI, 7 for obtuse marginal circumflex, 5 for right coronary artery （RCA）. Angiographic assessment of graft patency was performed in all patients during the PCI procedure. The clinical follow-up period lasts from 11-24 months. Results The in-hospital mortality was 0%. There was neither conversion to a full median sternotomy nor intraoperative complications. Ventilation time was 6.6 ＋_ 4.1 h. Blood loss ranged 341 ＋_ 78.8 mL. ICU stay ranged 22.3 _ 12.8 h. Hospital postoperative stay lasted for 6.5 ＋ 1.6 days. Prior to PCI patients showed 100% patent left internal mammary artery. One patient had mediastinitis （Tables 2-3）. Rate of freedom from cardiac reintervention during the follow-up period was 92.8% （13/14）. Conclusions The inferior J-shaped sternotomy is simple, reproducible, and the safest technique for performing minimally invasive coronary bypass surgery. MICAB ＋ PCI is also safe, feasible and efficacious.展开更多

METHODS: We performed Roux-en-Y gastric bypass with reserved gastric volume, a procedure in which gastrointestinal continuity was reestablished while excluding the entire duodenum and proximal jejunal loop. We observed the procedural success rate, long-term survival, and histopathological sequelae associated with a number of technical modifications. These included: use of anatomical markers to precisely identify Treitz's ligament; careful dissection along surgical planes; careful attention to the choice of regional transection sites; reconstruction using full-thickness anastomoses; use of a minimally invasive procedure with prohemostatic pretreatment and hemorrhage control; prevention of hypo-thermic damage; reduction in the length of the procedure; and accelerated surgical recovery using fast-track surgical modalities such as perioperative permissive underfeeding and goal-directed volume therapy. RESULTS: The series of modif ications we adopted reduced operation time from 110.02 ± 12.34 min to 78.39 ± 7.26 min (P < 0.01), and the procedural success rate increased from 43.3% (13/30) to 90% (18/20) (P < 0.01), with a long-term survival of 83.3% (15/18) (P < 0.01). CONCLUSION: Using a number of fast-track and damage control surgical techniques, we have successfully established a stable model of gastric bypass in diabetic rats.展开更多

We report our experience of hybrid minimally invasive approach in 15 patients. Methods From December 2012 to October 2013, 15 patients underwent revascularization of the left anterior descending artery through minimally invasive coronary artery bypass grafting （MIDCAB）. All patients by endoscopic assist beating heart coronary artery bypass grafting. Seven patients were scheduled for a hybrid procedure. Percutaneous coronary intervention of non- LAD was performed 3 to 5 days preoperatively. Demographic data, perioperative outcome, and annual follow-up were obtained from all the patients. Results In-hospital mortality was 6.67%. The rate of conversion to full median sternotomy was 13.3%. Ventilation time was 6.9 ± 5.1 h. Blood loss volume was 241 ± 67.8 mL. ICU stay was 21.3 ± 10.8 h. Hospital postoperative stay lasted for 7.5 ± 1.3 days. Prior to PCI patients showed 100% patent LIMA （Tables 3 and 4）. A mean follow-up was 8.5 months. One year graft patency rate was 100% （8/8 patients for 254-slice tomography）. Two patients required reintervention. Conclusions Minimally invasive hybrid coronary revascularization is a safe, feasible and efficacious approach with good results and should be performed in selected patients by surgeons with experience in minimally invasive bypass surgery plus collaboration with cardiologists, eluting stents.展开更多
