An experimental study was designed on the treatment of 8 superficial burn wounds and 5 wounds after removing the split-thickness skin grafts with 200GS permanent magnetic flat dressings, and some of the wounds were chosen at random which did not received any treatment and would be served as control. It was noted that the volume of exudate in the treatment group was 11.9 50.7％ less than that of the control group, and the total protein, the albumin and globulin contents in the treatment cases were far less in exudate than those of the control cases. It was concluded that the magnetic therapy not only decresed the exudate, but also diminished the amount of total protein, albumin and globulin in the exudating fluid and it was of benefit to wound recovery.
ObjectiveTo explain the advantage of laparoscopic endoscopic rendezvous procedures used to treat rectal carcinoma, and predict the future direction of the surgery methods for rectal carcinoma. MethodsA review and summary based on the clinical experience of our hospital and the published researches about the laparoscopic endoscopic rendezvous procedures over the past years in home and abroad were performed. ResultsLaparoscopy can monitor the situation of the abdominal cavity.Endoscopy can detect the location of rectal carcinoma.Laparoscopic endoscopic rendezvous procedures used to treat rectal carcinoma can combine the advantage of each other.And the purpose of "less invasion, less pain, and faster recovery" will be achieved.The effect of "1+1 > 2" will be realized. ConclusionLaparoscopy and transanal endoscopic microsurgery hybrid could be a naive form of nature orifice transluminal endoscopic surgery to treat rectal carcinoma.
The ulcer resulting from snake-bite injury was characterized by deep and wide tissue necrosis and secondary infection. The patient was at high risk of loss of function of his extremity. From 1989 to 1996, 16 cases with deep ulcer of the upper extremity resulting from snake-bite injury were treated with different types of axial thoraco-abdominal skin flaps, depending on the location of the ulcer. Thoraco-umbilical skin flap was used in 2 cases, lateral thoracoabdominal skin flap in 1 case, iliolumbar skin flaps in 5 cases, lower abdominal skin flaps in 6 cases, lower abdominal divided foliated skin flap in 1 case and Y-shaped hypogastric skin flap in 1 case. Reparative operation was carried out within 3 weeks after injury and primary repair were undertaken in 6 of them. The pedicles were divided in 17 to 24 days after operation. Twelve flaps survived. Three of the 6 flaps had mild signs of inflammation which disappeared after administration of antibiotics. One had necrosis of the distal part of the flap, and was healed with split skin graft. This type of skin flap was an ideal method for the treatment of snake-bite injury of the upper extremity.
OBJECTIVE This paper is aimed to observe the long-term result of reconstruction of wrist joint by replacing distal end of radius with vascularized fibular head in patient of giant tumor. METHODS From July 1978 to November 1993, 12 cases of giant tumor of distal end of radius were treated by this procedure and followed up for 6 months to 15 years, and the movement range of wrist, grip strength, and pain were evaluated. RESULTS The painful wrist released in 11 cases, only one case still existed mild pain and felt discomfortable. The average range of movement of wrist joint was 34.05 degree in volar flexion, 52.80 degree in dorsal extension, 26.25 degree in ulnar deviation, and 19.75 degree in radial deviation, and average grip strength was 44.6 kg. Compared with the contralateral side, there were accounted for 46.2%, 72.7%, 76.1%, 80.6%, and 76.7% respectively. CONCLUSION Replacement of distal end of radius with fibular head to reconstruct wrist joint can restore function of carpal joint, which is proved to be a safe and effective method.
Mitral regurgitation (MR) with multi-pathogenesis is a common disease in cardiac surgery department. MR can be classified into two categories-primary mitral regurgitation and secondary mitral regurgitation. With the development of cardiac intervention, numerous patients who cannot tolerate open heart surgery for the reason of high risk of surgery receive the treatment of intervention and achieve the favorable endpoint. The technique of transcatheter therapy which could be used to treat MR is comprised of leaflet repair, annuloplasty and implantation of artificial chordae. Comparing to primary mitral regurgitation, surgical effect of secondary mitral regurgitation is not desirable for the reasons of complex pathophysiologic mechanism. Hence, based on the perspective of surgeon, we will introduce the research progress of transcatheter interventional mitral valve repair which is focused on the treatment of primary mitral valve regurgitation and reviewed from three aspects of surgical risks, surgical types and outlook.
Objective To investigate the treatment and prognosis of moderate ischemic mitral regurgitation (IMR) in coronary artery disease(CAD). Methods From January 1998 to May 2006, 28 patients of CAD with moderate IMR underwent coronary artery bypass grafting (CABG) and mitral valve plasty(MVP, 24) or mitral valve replacement (MVR,4). The Reed method were used in 9 cases, the annuloplasty ring were used in 15 cases. Mechanical valve were implanted in 1 case and biological valve in 3 cases. Results There was no operative or hospital death. Twentysix patients were followed up to a mean period of 41 months. There were two late death(one was MVP, the other was MVR). In MVP cases, nineteen patients were in New York Heart Association (NYHA) functional class Ⅰ and Ⅱ, 3 in class Ⅲ, which was better than that of preoperative one. Ultrasonic cardiography (UCG) examination showed no mitral regurgitation in 5 cases, mild in 7, light in 6, moderate in 3, severe in 1. Left atrial volume (LAV) and left ventricular enddiastolic volume (LVEDV) were 54.1±12.7ml and 60.9±14.8 ml, decreased more significantly than that preoperatively (Plt;0.05). In MVR cases, 2 cases were survival and followed. One patient was in NYHA functional class Ⅰ, 1 in class Ⅱ, which was better than that of preoperative one. Conclusion Moderate IMR with CAD should be treated carefully. MVP with annuloplasty ring have better early results. For patients with bad heart function and abnormal left ventricular wall motion, the late results need more studies.
Objective To investigate the significance and surgical skill for lymphadenectomy around common hepatic artery in gastric cancer. Methods Two hundred and fifty-seven cases with undergoing lymphadenectomy around common hepatic artery in gastric cancer between January 2001 and December 2006 were retrospectively reviewed. Experiences and understanding of dealing with this procedure in curative gastrectomy for gastric cancer were concluded. Results The number of dissected No.8 lymph node was 2.2±1.7, and the positive rate of No.8 lymph node was 30.35%. There were no lymphadenectomy related complications, such as anastomotic leakage, lymphatic fistula and postoperative hemorrhage in this series. Dissection around common hepatic artery lymph nodes along artery intrathecal space, division and ligation of left gastric vein at its root, and sufficient exposure of anatomic structures were important to dissection lymph nodes around the common hepatic artery. The exposure of anatomic structures included liberation of common hepatic artery by traction with the band, and the exposure of posterior side of pancreas by Kocher incision.Conclusion Being familiar with the anatomy around common hepatic artery, careful dissection, and attention to the surgical skill of lymphadenectomy are very important to improve the effectiveness of lymphadenectomy around common hepatic artery in gastric cancer.
OBJECTIVE:To investigate the treatment of retinal redetachment after vitrectomy and silicone oil tamponade. METHODS:Investigating retrospectively on the treatment effect of 8 cases of redetachment of retina with proliferative vitreoretinopathy(PVR) in which the retinas had been attached formerly after vetrectomy and silicone oil tamponade operation.The reoperative procedures included pars plana vitrectomy,membranes peeling,retinotomy,inner exchange of the fluid and silicone oil tampnade and subretinal membranes were removed out in 2 eyes. RESULTS:Six eyes had anatomical reattachment postoperatively and another 2 eyes still had inferior shallow retinal detachment.Visual acuity was improved in 6 patients and remained unchange in 2 patients. CONCLUSIONS:The cause of recurrent retinal detachment might be the formation of the proliferative epiretinal and subretinal membranes,and vitrectomy to release the traction of proliferative membranes and full fluid silicone oil exchange should do good to reattachment. （Chin J Ocul Fundus Dis,1996,12: 13-15 ）
Seventen eyeswith complicated retinal detachment were repaired with vitrectomy,retinotomy,retinectomy or retinal suture combined with gas/fluid exchange,scleral buckle and cryotherapy.These cases include giant retinal tear with inverted retinal flap(6 eyes),severe traumatic retinal detachment(4 eyes),proliferative diabetic retinopathy(2 eyes),recurrent retinal detachmeng(3 eyes)and anterior proliferative vitreoretinopathy(2 eyes).The duration of follow up in 16 eyes was from 3 to 42 months.The retinal reattachment was in 10 eyes(62.5%),and visual acuity better than0.05 in 8 eyes(50.0%).Four eyes(25.0%)resulted in hypotony. （Chin J Ocul Fundus Dis,1996,12:7-9）
