【Abstract】Objective To investigate the effects and advantages of laparoscopic hernioplasty for hernia. Methods From June 1995 to June 2005, 222 patients with hernia were treated with laparoscopy. Transabdominal preperitoneal hernia repair (TAPP) were performed in 166 patients. Totally extraperitoneal hernia repair(TEP) were performed in 25 patients. Closure of the internal orifice of hernia was performed in 21 patients. Furthermore, incisional hernia in 2 patients, diaphragmatic hernia in 1 patient and mesenteric hernia in 1 patient were performed by laparoscopic hernioplasty and 6 patients with hernia of oesophagus finestra performed hernioplasty combined collapse gastric fundus with laparoscopy. In this series 45 patients associated with other abdominal disease were simultaneously treated with laparoscopy. Results All cases were operated successfully. The span of operation reduration was 42.5 min 〔(10～180 min)〕. The average length of postoperative hospital stay were 4.6 days. There was one early failure owing to the use of too small a piece of mesh.Conclusion The results indicate that mesh repair of hernias is a satisfactory technique with a low recurrence rate and a low major complication rate.
Abstract: Objective To investigate the feasibility of videoassisted thoracoscopic surgery (VATS) ronchial sleeve lobectomy for lung cancer, and to describe this treatment method. Methods Between December 2010 and April 2011, three patients in our hospital underwent VATS bronchial sleeve lobectomy as treatment for right upper lobe nonsmall cell lung cancer. The patients were one female and two males, aged 61, 65, and 62 years. Surgical incisions were the same as for singledirection VATS right upper lobectomy. The right superior pulmonary vein was firstly transected, followed by the first branch of the pulmonary artery. Then, the lung fissure was transected and the mediastinal lymph nodes, including the subcarinal nodes, were also dissected to achieve sufficient exposure of the right main bronchus. The bronchus was transected via the utility incision, and the anastomosis was accomplished by continuous suture with 30 Prolene stitches. Another 0.5 cm port in the 7th intercostal space at the posterior axillary line was added in the third operation for handling of a pair of forceps to help hold the needle during anastomosis. A sealing test was performed to confirm that there was no leakage after completion of the anastomosis, and the stoma was covered with biological material. Bronchoscopy was performed to clear airway secretions and to confirm that there was no stenosis on postoperative day (POD) 1. Results The lobectomy and lymph node dissection was finished in 5158 minutes (averaging 54.7), and the time needed foranastomosis was 4055 minutes (averaging 45.7). Total blood loss was 55230 ml (averaging 155.0 ml). Number of dissected lymph nodes was 1821 (averaging 19.3). One patient was diagnosed with adenocarcinoma of the right upper lobe with metastatic hilar lymph node invasive to the right upper lobar bronchus. The other two patients were both diagnosed with centrally located squamous cell carcinoma of the right upper lobe, and all the patients achieved microscopically negative margins. There was no stenosis of the anastomosis stoma, and the postoperative course was uneventful. These patients were discharged on POD 810 (averaging 8.7 days), and they recovered well during the followup period, which lasted 2 to 6 months. [WTHZ]Conclusion [WTBZ]For experienced skillful thoracoscopic surgeons, VATS bronchial sleeve lobectomy is safe and feasible. Making the incisions of a singledirection VATS lobectomy with an additional miniport may be an ideal approach for this procedure.
ObjectiveTo explore the clinical efficacy of modified polytetrafluoroethylene (PTFE) prosthesis rhinoplasty for correction of low nose and short columella. MethodsBetween August 2012 and August 2015, modified PTFE prosthesis rhinoplasty was used to correct low nose and short columella in 52 patients. There were 4 males and 48 females, aged 19 to 45 years (mean, 27 years). Primary rhinoplasty was performed in 47 cases; secondary rhinoplasty was performed in 5 cases, and it was 12-18 months from the first operation (mean, 15 months). During operation, a scaly sag ventral side was made by carving and moving cap shaped nose prosthesis was prepared, and nasal dorsumnasal columella prosthesis covered by tension-free flap was designed. At pre-operation and last follow-up, Image ProPlus 6.0 software was used to measure the nose length, nose depth, nose tip width, nostril/nose tip, nasolabial angle, and nasal tip rotation for evaluation of external nose shape correction; and ultrasound was used to measure the alar cartilage angle, alar two vertex distance, and nose tip to vertex distance for evaluation of internal soft tissue changes; the prosthesis position was observed by CT scan at 12 months. ResultsAll incisions healed by first intention, with no complications. All patients were followed up 7-36 months (mean, 20.4 months). At 12 months after operation, CT scans showed that prosthesis located in the middle of the nose and above nasal bone, septal cartilage and crus mediale cartilaginis alaris majoris in 45 patients; no prosthesis displacement was observed. At last follow-up, image measurement and ultrasound results showed external nose shape parameters (except nostril/nose tip) and internal soft tissue structures were significantly improved when compared with preoperative values (P < 0.05). ConclusionModified PTFE prosthesis rhinoplasty can effectively correct low nose and short columella, with small surgical trauma and good appearance.
Abstract： Objective To summarize the experiences and analyze the efficacy of mitral valvuloplasty in treating anterior leaflet prolapse. Methods A total of 152 consecutive nonrheumatic heart disease patients including 96 males and 56 females with anterior leaflet prolapse who underwent mitral valvuloplasty from February 1997 to March 2007 were analyzed retrospectively. The age of these patients ranged from 10 to 73 years old (38.54±17.22 years). There were 119 cases of mitral degenerative prolapse or chordae rupture, 24 of ongenital heart disease, 3 of ischemic mitral insufficiency, and 6 of native valve endocarditis. Echocardiography before operation showed the degree of mitral regurgitation was severe in 19, moderate to severe in 63, and moderate in 70 patients. Among the patients, 87 had anterior prolapse and 65 had bilateral prolapse. All patients underwent mitral valve repair under standard cardiopulmonary bypass. Results During the operation, transesophageal echocardiography and saline injection test showed satisfying results in all the patients. No early death occurred after operation. Followup was done to 135 patients for 3 months to 8.5 years with a followup rate of 88.82%. During the follow up, 93 patients were in New Yoke Heart Association（NYHA）class Ⅰ, 35 in Class Ⅱ, 3 in class Ⅲ and 4 in class Ⅳ. The Echocardiography showed that postoperative left atrium diameter (41.09±10.40 mm vs. 45.32±10.07 mm, t=4.186, P=0.000) and left ventricular enddiastolic dimension (52.04±7.74 mm vs. 60.70±7.72 mm,t=9.676, P=0.000) were significantly smaller than that before operation. No or trace mitral regurgitation (MR) was found in 36 patients, mild MR in 45 patients, mild to moderate MR in 38 patients, moderate MR in 9 patients, and moderate to severe MR in 7 patients. Mitral valve replacement was performed in 5 patients after valvuloplasty. Three died during the follow-up. Two of them died of heart failure and one of unknown cause. Conclusion In spite of the complexity, the longterm results of mitral valve repair for anterior leaflet prolapse are satisfactory if the best surgery method is chosen.
ObjectiveTo investigate the effectiveness of rotationplasty in treating osteosarcoma of distal femur in children.MethodsA clinical data of 10 children with osteosarcoma of distal femur treated with rotationplasty between March 2014 and June 2016 was retrospectively analyzed. There were 7 boys and 3 girls with an average age of 6.7 years (range, 4-10 years). There were 4 cases of osteoblastic osteosarcoma, 4 cases of mixed osteosarcoma, and 2 cases of chondroblastic osteosarcoma. All children were staged as Enneking stage ⅡB. The disease duration ranged from 3.5 to 6.0 months (mean, 4.6 months). The lower limb functional scoring system of 1993 Musculoskeletal Tumor Society (MSTS93), Toronto Extremity Salvage Score (TESS), and knee mobility were used to evaluate postoperative function. Tumor recurrence and metastases were monitored by radiograph.ResultsPoor superficial incision healing occurred in 1 patient, and healed after dressing change. The other incisions healed by first intention. All children were followed up 24-72 months (mean, 52.6 months). No local recurrence was observed during follow-up. Three of the ten patients suffered from metastases including 1 dying of multiple organ dysfunction syndrome, 1 alive with tumor, and 1 tumor free survival. Painful callosities and ulcers which related to prosthetic wear occurred in 2 patients and turned up after optimizing prosthetic fit and physiotherapy. The fracture healing time was 2.5-5.0 months (mean, 3.5 months). All children could walk independently at 4 months postoperatively. At last follow-up, the MSTS93 score was 19-25 (mean, 22) and the TESS score was 87-93 (mean, 90). The extension of knee joint mobility with artificial limbs was 0°-10° (mean, 5°), and the flexion of knee joint mobility with artificial limbs was 85°-95° (mean, 90.5°).ConclusionRotationplasty in treating osteosarcoma of distal femur in children with limb salvage difficulties can effectively preserve the limb function and improve the quality of life, and it can be used as an alternative to amputation.
【Abstract】ObjectiveTo evaluate the therapeutic benefits of three styles of hernioplasties such as the traditional hernioplasty, the mesh only hernioplasty and the plug amp; mesh hernioplasty. MethodsThe traditional hernioplasty in 534 cases(583 sides), the mesh only hernioplasty in 57 cases(60 sides) and the plug amp; mesh hernioplasty in 51 cases(54 sides) were performed. The comparing studies on the operative time, the postoperative complications, the recurrent rate and so on were analyzed. ResultsThe average operative time of the traditional styles group was (34.26±4.56) min, which was significantly shorter than the mesh only group 〔(40.35±6.24) min, P＜0.05〕 and the plug amp; mesh group 〔(49.12±8.69) min, P＜0.01〕 respectively. This significant difference between the mesh only group and the plug amp; mesh group was also identified (P＜0.05). Postoperative complications in the traditional styles group, the mesh only group and the plug amp; mesh group were 1.12%, 1.75% and zero,respectively (Pgt;0.05). Recurrent rate in the traditional styles group was 5.99%(32/534), which was significantly higher than that of the mesh only and the plug amp; mesh group (no recurrence). The average hospitalizing time in the traditional styles group, the mesh only group and the plug amp; mesh group was (7.11±3.06) days，（5.38±2.53） days and （6.19±3.61） days, respectively, in which there was no significant difference among groups. The activityrecovering time in the traditional styles group was (16.98±4.35) days, which was significantly longer than （7.26±2.46） days in the mesh only group and （8.02±3.35） days in the plug amp; mesh group. Conclusion The mesh only hernioplasty or the plug amp; mesh hernioplasty have a lower recurrent rate comparing with that in the traditional hernioplasty, which should be much more popularly applied in the treatment of inguinal hernia.
ObjectiveTo investigate the effect of platelet rich plasma (PRP) in promoting wound healing of total hip arthroplasty (THA). MethodsBetween January 2011 and January 2012, 80 patients scheduled for THA and accorded with the inclusion criteria were divided into 2 groups:wounds were treated with PRP in 40 patients (PRP group) and with normal saline in 40 patients (control group). There was no significant difference in gender, age, disease duration, injury causes, sides, fracture type, and preoperative Harris hip scores between 2 groups (P>0.05). Routine drainage and functional exercise were performed after operation. ResultsThe postoperative drainage volume of PRP group[(137±26) mL] was significantly lower than that of control group[(424±39) mL] (t=38.726, P=0.000). At 4 days after operation, no inflammatory reaction was observed in 34 cases of PRP group and in 30 cases of control group, mild inflammatory reaction in 5 cases of PRP group and in 6 cases of control group, moderate inflammatory reaction in 1 case of PRP group and in 4 cases of control group; there was no significant difference between 2 groups (χ2=2.141, P=0.343). Wound healed by first intention in 40 patients of PRP group and in 39 patients of control group, showing no significant difference between 2 groups (P=1.000). The average follow-up period was 9 months (range, 6-12 months). The Harris hip scores of PRP group (90.2±2.5) and control group (89.3±3.1) at last follow-up were significantly better than those before operation (39.6±8.9 and 39.2±9.2 respectively) (t=34.618, P=0.000; t=32.638, P=0.000), but no significant difference was found between 2 groups (t=1.429, P=0.153). ConclusionUsing PRP in THA wound can reduce postoperative drainage volume, improve the healing of operation incision. It is a safe, effective, and promising procedure in treatment of THA wound.
ObjectiveEvaluating the clinical efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) for osteoporotic vertebral compressive fracture (OVCF). MethodsPatients with OVCF were retrospectively analyzed from Feb. 2008 to Feb. 2013 in Department of Orthopaedics, Tianjin Medical University General Hospital. Patients were divided into the PVP group and the PKP group. The VAS, vertebral kyphosis angle, vertebral height and bone cement leakage of both groups were compared, and the SPSS13.0 software was used for data analysis. ResultsA total of 55 patients were included. Of which, 25 patients were in the PVP group and 30 patients were in the PKP group. All patients were followed up from 5 to 20 months, with an average time of 15.5 months. The VAS scores in both groups were all improved after the operation (P<0.05), but no significant difference was found between both groups. The vertebral kyphosis angle in both groups were improved after the operation (P<0.05), and the PKP group was better than the PVP group. Six patients in the PVP group occurred the leakage of bone cement, and 4 patients in the PKP group. Five patients in the PVP groups occurred vertebral fracture again, while 7 patients in the PKP group. ConclusionUsing PVP and PKP for the treatment of OVCF can quickly relieve pain and increase the stability of the vertebral body. PKP can restore vertebral body height better and reduce the incidence of cement leakage.
Objective To evaluate the surgical effects of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins stripping on primary deep venous valvular incompetence of the lower limb.Methods Seventy-eight patients (92 limbs) with primary deep venous valvular incompetence of the lower limbs received the operations of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins from 1997 to 2004. There were 65 males and 13 females, and their ages ranged from 32 years to 72 years (mean age of 52.5 years). The valvular reflux grades of these 92 limbs varied from Ⅲ to Ⅳ according to Kistner’s standard. A sleeve made from the stripped great saphenous vein was used in the indirect loop valvuloplasty of the superficial femoral vein. The early results of surgery were retrospectively analyzed. Results Pre-operative symptoms, such as edema, ulceration, pigmentation and heavy feeling of the performed limbs disappeared or were remarkably improved in 65 cases (76 limbs) after operation. Eight cases (10 limbs) had alleviative symptoms compared with pre-operative ones. Meanwhile, no improvement of symptoms was observed in 3 patients (4 limbs). Acute ilio-femoral vein thrombosis occurred in 2 patients (2 limbs), which manifested as more servious edema of the lower limbs than those before operation. The overall effective rate of surgery was 93.5%（86/92）, and the complications rate was 2.2% (2/92). Conclusion Indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose vein stripping is an effective and convenient way to correct the primary deep venous valvular incompetence of the lower limb. The surgical indications of this disease should be emphasized strictly to assure the good outcomes.
