ObjectiveTo evaluate the surgical techniques, perioperative complications, clinical outcomes of the modified Stoppa approach in the treatment of acetabular anterior and posterior column fractures.
MethodsBetween March 2008 and October 2014, 42 cases of acetabular anterior and posterior column fractures were treated by modified Stoppa approach or modified Stoppa approach combined with iliac fossa approach, and the clinical data were retrospectively analyzed. There were 20 females and 22 males with an average age of 43.2 years (range, 19-68 years). Fractures were caused by traffic accident in 21 cases, by falling from height in 16 cases, and by heavy pound in 5 cases. The time from injury to operation was 3-15 days (mean, 6 days). According to fracture classification of Letournel-Judet, there were 20 cases of both column fractures, 15 cases of anterior and posterior hemi-transverse fractures and 7 cases of T-shaped fractures. The intraoperative blood loss, the amount of blood transfusion, the operation time, the volumn of drainage, and complication were recorded. Matta radiological standard was used to evaluate the reduction quality of fracture, and Merled'Aubigné-Postel system to evaluate hip function.
ResultsThe average intraoperative blood loss was 900 mL; the average amount of blood transfusion was 400 mL; the average volume of drainage was 110 mL; and the average operation time was 165 minutes. Intraoperative complications included 4 cases of tractive injury of obturator nerve and 2 cases of the external iliac vein injury, and postoperative complications included 2 cases of lateral femoral cutaneous nerve palsies and 1 case of deep vein embolism of lower extremity, which were improved after treatment. The patients were followed up 36 months on average (range, 12-48 months). There was no infection or heterotopic ossification. According to Matta radiological evaluation system, the reduction quality of fractures was rated as excellent in 21 cases, good in 16 cases, and poor in 5 cases, with an excellent and good rate of 88.1%. The healing time of fracture was 3.5-8.0 months (mean, 5.1 months). According to Merled'Aubigné-Postel system for hip function, 20 cases were graded as excellent, 15 cases as good, 4 cases as fair, and 3 cases as poor, with an excellent and good rate of 83.3% at last follow-up.
ConclusionModified Stoppa approach or with iliac fossa approach can get full exposure of quadrilateral area, good reduction, and firm internal fixation in the treatment of acetabular fractures associated with T-shaped fractures, both column fractures, anterior and posterior hemi-transverse fractures.
Objective To increase the success rate of vaginal reconstruction with pudendal-thigh flap, reduce the chance of hemocirculatory disorder and rel ieve the deformity of greater l ip of pudendum and vaginal orifice. Methods FromJune 1998 to May 2004, 15 patients, 2 males with transsexual ism and 13 females with vaginal absence, aged 23-31 years old (26.2 on average), received vaginal reconstruction. Arterial perforator was detected at 3 cm laterally away from the mid-point between the vaginal orifice and the anus. The flap of 12.0 cm × 5.5 cm was designed at the lateral of the greater l ip of pudendum, with the groin as the axis. After the flap was elevated beneath the deep fascia, the fascial pedicle was partially severed from lateral to medium, keeping the perforator intact into the flap. Then the flap was transferred through the tunnel to the socket. The inner layer and the orifice were formed. Results All flaps survived, and the contour of the vulva was satisfactory. Among the 15 patients, 14 patients’ incisions obtained heal ing by first intention, and only 1 male with transsexual ism was discovered to suffer from rectovaginal fistula at the remote juncture of the two flaps at 7 days after the operation. By taking out all the gauze and cleaning the feces, the fistula healed automatically. All patients were followed up for 6 months-3 years. The reconstructed vagina was about 10 cm deep and 2 fingers wide. One female’s vagina was found pilous at 20 months after the operation, and no special treatment was given. The other patients’ vaginal inner walls were smooth and complete. Two female patients had the experienceof sexual intercourse and felt satisfied after using lubricant. Conclusion The modified pudendal-thigh flap has rel iable blood supply and makes the transferring during vaginal reconstruction more convenient and the contour of the vulva more satisfactory.
ObjectiveTo explore a surgery of effective weight loss concentrating on gut hormone release. MethodsWistar rats were fed with high-fat diet for inducing obesity and which randomly divided into sleeve gastrectomy plus decent jejunoileal bypass (SJB) group (n=12), sleeve gastrectomy (SG) group (n=12), and sham operation (SO) group (n=11), the body weight reduction, food intake, plasma ghrelin level, and glucagon like peptide-1 (GLP-1) level were compared among three groups. ResultsThere were no differences of the body weight and food intake before operation among three groups (Pgt;0.05). Compared with the SO group, the body weight descended and the food intake decreased obviously on 1-8 weeks after operation in the SJB group (Plt;0.05), the body weight of rats on 1-8 weeks after operation in the SJB group significantly descended as compared with the SG group (Plt;0.05), and the food intake of rats on week 3, 6, 7, and 8 in the SJB group signicantly decreased as compared with the SG group (Plt;0.05). There were no differences of the levels of the plasma ghrelin and GLP-1 before operation among three groups (Pgt;0.05). Compared with SO group, the plasma ghrelin level decreased and the GLP-1 level increased in the SJB group and the SG group, meanwhile the SJB group significantly decreased level of plasma ghrelin and elevated level of plasma GLP-1 as compared with the SG group on week 8 after operation(Plt;0.05). ConclusionThe data demonstrate that SJB could represent an effective way of losing weight by interfering with food intake and obesity related hormone levels.
Objective To compare the therapeutic effects between endoscopic thyroidectomy by anterior chest approach and modified Miccoli thyroidectomy. Methods Sixty patients with thyroid goiter were performed endoscopic thyroidectomy by anterior chest approach (endoscopic thyroidectomy by anterior chest approach group, n=30) and modified Miccoli thyroidectomy (modified Miccoli group, n=30) respectively. The operative time, the drainage volume, cosmetic benefit, the postoperative hospitalization time, the expenses of hospitalization and postoperative complications of two groups were compared. Results The operative time and the drainage volume after operation of endoscopic thyoidectomy by anterior chest approach group were significantly more than modified Miccoli group 〔(99.9±23.4) min vs. (74.0±29.6) min; (68.6±8.7) ml vs. (40.9±6.1) ml, respectively〕, Plt;0.05. The cosmetic benefit score of endoscopic thyoidectomy by anterior chest approach group was higher than that of modified Miccoli group 〔(4.7±0.2) points vs. (3.7±0.1) points〕, Plt;0.05. The postoperative hospitalization time and expenses of hospitalization were no significant differences between the two groups 〔(6.5±1.7) d vs. (5.5±0.9) d; (9 328.3±1 107.1) yuan vs. (8 568.2±1 032.3) yuan, respectively〕, Pgt;0.05. One case had transient hoarseness in 2 groups respectively, no other complications happened. Conclusions Modified Miccoli operation is both minimally invasive and cosmetic, but endoscopic thyroidectomy by anterior chest approach has better cosmetic benefit, which can release patients’ psychological trauma. The patients with specific cosmetic demand may choose endoscopic thyroidectomy by anterior chest approach.
Objective To investigate the clinical effects and the management of combined using of zerobalanced ultrafiltration(ZBUF) and modified ultrafiltration(MUF) in severe infant open heart surgery with cardiopulmonary bypass(CPB) , in order to evaluate the feasibility and clinical significance of combination of ZBUF and MUF. Methods 20 pediatric patients diagnosed as complicated congenital heart disease had been involved, which included 12 males and 8 females with 12.6±7.5months of age and 8.5±3.3 kg of weight. Gambro FH22 hemofilter was selected in all patients. The typical MUF method was chosen. ZBUF was done during CPB and MUF was performed after CPB. The variety of hemodynamics, blood gas, concentration of electrolytes, inflammatory media and change of the plasma colloid osmotic pressure(COP) were measured at several time points. Filtrate was salvaged to detect the level of tumor necrosis factor alpha (TNF-α) and interleukine-8 (IL-8). Results Mean arterial pressure(MAP) was significantly higher(P=0.001) after MUF finished in all patients. Lactate acid (LAC), TNF-α and IL-8 had no significant difference before and after ZBUF. COP was significantly higher after MUF than that after ZBUF(P=0.002). Concentration of TNF-α in MUF filtrate was significantly higher than that in ZBUF(p=0.036). Conclusion Combined using of ZBUF and MUF has the effective ability of removing the inflammatory mediators and ameliorating system immunoreaction in pediatric CPB. MUF can improve the respiratory and heart function through decreasing the body water and increasing COP and hematocrit.
Objective To evaluate the value of extended latissimus dorsi flap (ELDF) in immediate breast reconstruction in patients with breast cancer after modified radical mastectomy. Methods Thirty-six patients with breast cancer who accepted modified radical mastectomy and 12 patients with breast cancer who accepted immediate breast reconstruction after modified radical mastectomy from January 2008 to June 2009 were included. The complications, cosmetical results and quality of life of these patients were compared. The shape of breast reconstruction was also evaluated. Results All of 12 patients succeeded in proceeding immediate breast reconstruction with ELDF. The evaluation of shape of breast reconstruction was good in 6 cases, secondary in 4 cases, and bad in 2 cases, which was beyond that in patients of radical operation group (Plt;0.001). There was no statistical difference in operation complications as hydrops, necrosis, affecting limb shoulder joint motion, drainage time, hospital stay, and starting time for adjuvant therapy between two groups (Pgt;0.05). The patients in breast reconstruction group had a better quality of life compared with the patients in radical operation group (Plt;0.001). In breast reconstruction group, 10 patients received adjuvant chemoradiotherapy and no necrosis was showed in local flap grafting. After the follow-up of 2-17 months (median 8 months), no local recurrence and metastasis was demonstrated in two groups patients. Conclusions There are good cosmetic results after immediate breast reconstruction with ELDF, and it is easy to operate. It is a safe and feasible therapeutics method for early breast cancer.
ObjectiveTo explore the feasibility and accuracy of modified three longitudinal and five transverse method in locating perforating branches before anterolateral thigh perforator flap (ALTP) repair.MethodsBetween January 2019 and December 2019, 41 patients with skin and soft tissue defects were repaired with ALTP. There were 31 males and 10 females. The age ranged from 18 to 61 years, with an average of 32 years. The soft tissue defects were caused by trauma in 38 cases, and the time from injury to operation was 3-7 days, with an average of 4 days. The wounds left after excision of scar contracture deformity because of burn in 3 cases. Soft tissue defects located at upper limbs in 16 cases and lower limbs in 25 cases. The size of soft tissue defects ranged from 10 cm×4 cm to 25 cm×12 cm. Before operation, zonesⅠ, Ⅱ, Ⅲ, and Ⅳwere formed on the anterolateral thigh by modified three longitudinal and five transverse method. The perforating branches were detected in these four zones by Doppler ultrasound, and the skin flaps were designed according to the wound area. The perforating branches were explored during operation, and the distribution and types of perforating branches in each zone and the relationship between perforating branches and lateral femoral cutaneous nerve were observed. The ALTP with the size of 12 cm×5 cm to 30 cm×10 cm was used to repair the wound, and the donor site was sutured directly or repaired with the flap. ResultsA total of 117 perforating branches were detected in 41 patients before operation, and 111 perforating branches were found during operation, with a false positive rate of 5%. The probability of perforating branches in zonesⅠ, Ⅱ, Ⅲ, and Ⅳ were 56%, 73%, 76%, and 66% respectively, and the false positive rates were –9%, 7%, 16%, and 4%, respectively. All perforating branches located near the trunk of lateral femoral cutaneous nerve, especially in posterolateral area. There were only 1 perforating branch in 6 cases, 2 perforating branches in 12 cases, 3 perforating branches in 10 cases, and 4 perforating branches in 13 cases. The main types of perforating branches in zonesⅠ, Ⅱ, Ⅲ, and Ⅳ were transverse perforating branches, oblique perforating branches, descending perforating branches, and descending perforating branches, respectively. Partial distal necrosis occurred in 2 cases and complete necrosis occurred in 1 case after operation, and the wounds were repaired with skin grafts. The remaining 38 flaps survived successfully, and the wounds and the incisions of donor sites healed by first intention. All patients were followed up 3 to 12 months, with an average of 6 months. The appearance and texture of the skin flap were acceptable, and linear scar remained in the donor site.ConclusionIt can simply locate and distinguish the perforating branches and better protect the lateral femoral cutaneous nerve by using the modified three longitudinal and five transverse method before ALTP repair.
ObjectiveTo introduce a modified sutureless technique and its surgical results in the treatment of total anomalous pulmonary venous connection (TAPVC).MethodsClinical data of 11 patients with TAPVC who underwent the modified sutureless technique treatment from 2014 to 2019 in our center were retrospectively analyzed, including 4 males and 7 females. The median surgical age was 1.4 (0.3, 27.0) months. The median weight was 4.3 (3.5, 8.5) kg.Six (54.5%) patients were of supracardiac subtype, and five (45.5%) patients were of infracardiac subtype. Five (45.5%) patients had preoperative severe pulmonary hypertension, and three (27.3%) patients had preoperative pulmonary vein obstruction. The surgical results were compared with those of 10 patients treated with conventional surgical technique.ResultsThe median follow-up was 12 (range, 1-65) months. During the follow-up, no death or postoperative pulmonary vein obstruction occurred in the modified sutureless technique group. The perioperative data and relief of re-obstruction were superior in the modified sutureless technique group, but the difference was not statistically significant (P>0.05). The postoperative survival of the the modified sutureless technique group was better than that of the traditional surgery group (P=0.049).ConclusionThe modified sutureless technique which includes partial suture and then incising, and eversion of pulmonary vein incision, is a safe and reliable method for the treatment of TAPVC with satisfactory short-term results.
Eight patients treated with modified radical mastectomy and fenestration of pectoralis muscle to preserve pectoral, nerves are reported and the practical procedure is introduced. The results indicate that this method can overcome the disadvantage of mastectomy (Auchincloss) in that only dissection of fatty tissue and lymph nodes in the lateral part of axilla is carried out. With fenestration of pectoralis major muscle, not only the pectoral nerves can be perserved but also the fatty tissue and lymph nodes, including of those medial to the pectoralis minor, subclavicular and interpectoral nodes can be dissected. This method almost reached Halsted’s demand and it can be used for stage Ⅰ-Ⅱ, and even stage Ⅲ breast cancer if no infiltration to pectoralis major muscle is found.
Objective To construct an evaluation index system of the competitiveness of private hospitals, and to provide references for guiding, supervising, and managing the high-quality development of private hospitals. Methods An index pool was constructed by the literature analysis method. Index screening was completed using the modified Delphi method. The analytic hierarchy process, entropy weight method, and combination weight method were used to determine the index weight. Results The competitiveness evaluation index system of private hospitals was constructed, which included 5 primary indexes and 36 secondary indexes. The combination weight methods were resource allocation (0.366 8), service capacity (0.470 8), service efficiency (0.033 7), quality and safety (0.121 3), and financial management (0.007 3). Conclusion The constructed evaluation index system of competitiveness of private hospitals is scientific, targeted, and operable.
