Abstract： Objective To evaluate clinical outcomes of endoscopic vein harvesting （EVH）for coronary artery bypass grafting（CABG） in diabetic patients. Methods In this prospective non-randomized control study, patients with type 2 diabetes who underwent CABG from December 2010 to Febuary 2012 in West China Hospital were enrolled. Based on different vein graft harvesting technique, these patients were divided into two groups: an EVH group and a conventional vein harvesting（CVH）group. Perioperative complications were compared between the two groups. Interventional or CT coronary angiogram was used to evaluate bypass graft patency during follow-up. Results A total of 51 patients with type 2 diabetes were enrolled in this study with 24 patients in the EVH group and 27 patients in the CVH group. There was no statistical difference in age, weight, and comorbidities between the two groups. There was no statistical difference in cardiopulmonary bypass time and aortic cross-clamping time between the two groups （67.2±9.8 min versus 68.3±14.5 min, P＞0.05; 62.4±11.3 min versus 65.2±10.3 min, P＞ 0.05）. The vein graft harvesting time （35.6±6.4 min versus 45.2±11.4 min, P＜ 0.05）and rate of delayed leg wound healing（0.0% with 0/24 versus 18.5% with 5/27, P＜0.05） of the EVH group were significantly shorter or lower than those of CVH group.There was no statistical difference in major postoperative complications with respect to venous graft failure rate and chest pain during short term follow-up（9.1 months in the CVH group and 9.4 months in the EVH group） between the two groups. Conclusion EVH is a safe, effective, minimally invasive and quick vein graft harvesting technique for CABG in diabetic patients.
Objective To evaluate the cl inical results of posterior microendoscopic foraminotomy in the treament of cervical radiculopathy and cervical intervertebral disc protrusion. Methods From February 2004 to June 2007, 24 cases of cervical radiculopathy received posterior microendoscopic foraminotomy. There were 16 males and 8 females, aging 42-68 years (59 years on average), including 16 cases of cervical radiculopathy and 8 cases of cervical intervertebral disc protrusion.The course of disease was 6-15 months. The affected intervertebral discs were C4, 5 in 8 cases, C5, 6 in 12 cases, and C6, 7 in 4 cases. The radiological examinations showed that 8 protrusions included 6 soft tissue protusions and 2 rigid tissue protusions, and that cervical radiculopathy were caused by yellow l igament hypertrophy, Luschka’s joint hyperplasia, and abnormal position of facet joint. According to Japanese Orthopedic Association (JOA), the score before operation was (12.60 ± 1.52) points. Results The operation time was 90 to 120 minutes (100 minutes on average), the bleeding during operation was 100 to 150 mL (120 mL on average). Nerve root pain were rel ieved completely in 19 cases and were rel ieved partly in 4 cases. One case of calcified nucleus pulposus had neurological traction injury and recovered completely after 3 months. All cases were followed up 24-36 months (28 months on average). The radiological examinations after operation showed the intervertebral disc site was decompressed completely and the height of intervertebral disc and the cervical segmental al ignment were normal. At 24 months postoperatively, the JOA score was (16.10 ± 0.29) points, showing significant difference when compared with that of preoperation (P lt; 0.01). Conclusion The posterior microendoscopic foraminotomy can get to the operation site with miniincision, decrease tissue damage during operation, and avoid narrow intervertebral space, so it has satisfactory cl inical results.

Methods From June 2005 to October 2007, 20 patients with cranionasal tumor were treated. There were 10 males and 10 females, aged between 13 and 77 years (median 49 years). The disease course was 2 months to 13 years.The cranionasal tumors, proved by MRI and CT scans, located in the anterior skull base, paranasal sinus, nasal and/or orbit cavity. And their cl inical presentations were l isted as follows: dysosphresia in 14 patients, headache in 11 patients, nasal obstruction in 9 patients, epistaxis in 8 patients, visual disorder in 4 patients, exophthalmos in 4 patients and conscious disturbance in 2 patients. All 20 patients underwent transbasal surgery combined with transnasal surgery, and tumors were resected by one-stage operation. The skull base was reconstructed by surgical technique “Pull Down Sandwich” with pedicle periosteum flap. Results Tumors were resected by one-stage operation, and the anterior skull bases were reconstructed. Pathological examination showed 8 cases of mal ignant tumors and 12 cases of benign tumors. The total surgical excision was complete in 16 patients, and 4 patients with subtotal excision. There was no operative death. Eighteen patients were followed up 3 months to 2 years and 6 months. Transient cerebrospinal fluid rhinorrhea was found in 2 cases which were cured by lumbar drainage. And recurrence of tumor was observed in 5 patients 3 months to 2 years after operation. Conclusion Microsurgical operation via subfrontal approach assisted bytransnasal endoscopy is an effective method in management of cranionasal tumors, with the advantages of econstruction of the skull base with pedicle periosteum flap or “Pull Down Sandwich” and low compl ication rate.

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.
Objective To explore the clinical comprehensive therapy of Peutz-Jeghers syndrome. Methods From January 2000 to December 2010，71 cases of Peutz-Jeghers syndrome underwent endoscopic polyp resection firstly，and those with unresectable lesions or with severe complications underwent rescue laparotomy. After endoscopic or surgical treatment，the patients took Celecoxib capsules voluntarily for 6 to 9 months under informed consents. All cases were followed up from 6 months to 8 years. Results Twenty-nine patients had familial history of Peutz-Jeghers syndrome among the 71 patients （41 males and 30 females）. Sixty-two cases underwent 94 surgeries and intussusception was the most common cause of laparotomy. Sixty-five patients underwent 169 double-balloon endoscopy （DBE） therapies，and a total of 1 714 polyps were resected by DBE polypectomy. The largest major axis of small-bowel polyp was 8 cm. No severe complications occurred after DBE polypectomy except for 3 cases of intestinal perforation. Eight patients took Celecoxib capsule，3 of them were treated more than 6 months，and DBE examination showed the gastrointestinal polyps reduced in number and size. Conclusion The comprehensive treatment （including of endoscopic therapy，operation，and drug intervention） is a safe and effective clinical model to treat Peutz-Jeghers syndrome．
