ObjectiveTo investigate the therapeutic effect of modified side-to-end lymphaticovenular anastomosis in the treatment of post-mastectomy upper limb lymphedema. MethodsBetween May 2010 and May 2011, 11 female patients with post-mastectomy upper limb lymphedema underwent a modified side-to-end lymphaticovenular anastomosis. The average age was 49.5 years (range, 38-55 years). Lymphedema occurred at 7-30 months (mean, 18.3 months) after resection of breast cancer, with an average disease duration of 25.5 months (range, 10-38 months). The left upper limb was involved in 5 cases and the right upper limb in 6 cases. In accordance with difference value between health and affected sides criteria, 5 cases were rated as moderate, and 6 cases as severe. ResultsModified side-to-end lymphaticovenular anastomosis was successfully completed in all patients. Primary healing of incision was obtained in the other patients except 1 case of delayed healing. All patients were followed up for an average of 38.4 months (range, 36-40 months). Limb pain and swelling were relieved; no episodic attack or recurrence was observed. The circumference of affected upper arm was significantly decreased from preoperative (33.9±3.7) cm to postoperative (31.0±3.5) cm at 6 months and (30.9±3.5) cm at 36 months (P<0.05), but no significant difference was found between at 3 and 6 months (P>0.05); the circumference of affected forearm was significantly decreased from preoperative (30.1±3.6) cm to postoperative (27.8±3.4) cm at 6 months and (27.7±3.3) cm at 36 months (P<0.05), but no significant difference was shown between at 6 and 36 months (P>0.05). According to Campisi evaluation standard to assess efficacy, the results were excellent in 3 cases, good in 6 cases, and improved in 2 cases. ConclusionUsing modified side-to-end lymphaticovenular anastomosis may be effective in the treatment of upper limb lymphedema after mastectomy.
ObjectiveTo evaluate the value of incision closure device in laparoscopic cholecystolithotomy. MethodsThe clinical data of 130 patients underwent laparoscopic cholecystectomy from Oct. 2014 to Feb. 2015 were retrospectively analyzed. According to the methods of gallbladder suture, 130 cases were divided into two groups, 72 cases underwent traditional manual suture (MS group), and 58 cases underwent incision closure device (ICD group). The operative time, postoperative gastrointestinal function recovery time, bleeding volume, postoperative hospitalization time, hospitalization expenses, complications, and postoperative 6-12 months follow-up of patients in 2 groups were observed.Results One hundred and thirty cases were performed laparoscopic cholecystolithotomy successfully. The operative time and postoperative gastrointestinal function recovery time of ICD group were significantly shorter than those of MS group, the difference was statistically significant (P < 0.05). The hospitalization expenses of the patients in ICD group were significantly higher than those in the MD group (P < 0.05). There were no significant difference between the two groups in the bleeding volume and postoperative hospital stay (P > 0.05). The patients were followed up for 6-12 months, with an average of 8 months, and no complications occurred and stone recurrence. ConclusionIncision closure device can shorten the time of laparoscopic cholecystolithotomy and postoperative recovery of gastrointestinal function, but the cost is higher. Next development, still need decrease the expend and strengthen clinical promotion.

Twenty one cases were followed-up, the follow-up time ranged from 5 to 40 months with a median time of 19 months. 1-, 2-, and 3-year cumulative survival rates was 66.7%, 38.1%, and 19%, respectively. ConclusionSelective application of pancreatoduodenectomy with extended lymphadenectomy in resectable pancreatic head carcinoma is conducive to increase the proportion of the radical resection and improve the prognosis, but the postoperative complications is higher.
ObjectiveTo discuss the effectiveness of Poking reduction with shoulder arthroscopy-assisted surgery for displaced scapular neck fracture. MethodsBetween January 2009 and January 2012,9 cases of displaced scapular neck fracture underwent shoulder arthroscopy-assisted surgery for Poking reduction treatment.Of 9 cases,6 were men,and 3 were women,aged 21-54 years (mean,39 years).The causes were traffic accident injury in 7 cases,falling injury from height in 1 case,and hurt injury in 1 case.The shoulder abduction,flexion,and external rotation were obviously limited.X-ray films showed all cases had obvious displaced scapular neck fracture.Three-dimensional reconstruction of CT showed a grossly displaced of fracture.The time of injury to surgery was 4-27 days (mean,11 days). ResultsPatients obtained healing of incision by first intension,without infection,neurovascular injury,or other surgery-related complications.All patients were followed up 19-31 months (mean,23 months).X-ray films showed scapular neck fractures healed from 7 to 11 weeks (mean,8 weeks).At last follow-up,the shoulder abduction,flexion,and external rotation activity were improved significantly when compared with ones at preoperation (P<0.05);the shoulder Constant score,American Shoulder and Elbow Surgenos (ASES) score,and Rowe score were significantly better than preoperative scores (P<0.05). ConclusionThe reduction of displaced scapular neck fracture is necessary,and arthroscopic Poking reduction and fixation for displaced scapular neck fracture can reconstruct the shoulder stability and reduce complications
ObjectiveTo evaluate the arthroscopic treatment effectiveness of popliteal cyst excision in combination with debridement of the knee under local anesthesia by comparing with continuous epidural anesthesia. MethodsBetween June 2002 and January 2013,145 patients with popliteal cyst underwent arthroscopic popliteal cyst excision in combination with debridement of the knee under local anesthesia (local anesthesia group).In addition,51 patients with popliteal cyst were treated with the same surgery under continuous epidural anesthesia between February 2000 and August 2005 served as control group.No significant difference was found in gender,age,side,disease duration,or cyst size between 2 groups (P>0.05).Then,anesthesia time,analgesia effect,anesthesia satisfaction,operation time,bleeding volume,and anesthesia complication were compared between 2 groups.The guidelines of Rauschning and Lindgren were used to assess the effectiveness,and recurrence rate was recorded. ResultsAll incisions healed primarily,no neurological or vascular injury was found.The patients were followed up 1 year and 1 month to 8 years (mean,3.7 years) in local anesthesia group,and 8 years to 13 years and 7 months (mean,10.8 years) in control group.Local anesthesia group had shorter anesthesia time,higher visual analogue scale (VAS) score,shorter operation time,and lower bleeding volume (P<0.05) than control group.Anesthesia satisfaction was reduced in local anesthesia group,but there was no significant difference (χ2=0.071,P=1.000).The anesthesia complication incidence of control group (15.7%,8/51) was significantly higher than that of local anesthesia group (0) (P=0.000).Recurrence was found in 12 patients of local anesthesia group (curative ratio 91.7%) and in 5 patients of control group (curative ratio 90.2%),showing no significant difference (χ2=0.111,P=0.774).According to the guidelines of Rauschning and Lindgren,there were 131 cases of grade 0,13 cases of grade I,and 1 case of grade Ⅱ in local anesthesia group,and 37 cases of grade 0,12 cases of grade I,and 2 cases of grade Ⅱ in control group; significant differences in grading were shown between at pre- and post-operation in 2 groups (Z=-10.683,P=0.000; Z=-6.385,P=0.000),and between 2 groups at post-operation (Z=-3.145,P=0.002). ConclusionCompared with under continuous epidural anesthesia,arthroscopic treatment of popliteal cyst excision under local anesthesia can obtain better results.Under local anesthesia,the condition of nerve and vessel can be timely and dynamically observed.Arthroscopic treatment of popliteal cyst excision in combination with debridement of the knee has the advantages of less trauma,lower recurrence rate,and satisfactory results.
ObjectiveTo explore the effectiveness of bone transportation by ring type extenal fixator combined with locked intramedullary nail for tibial non-infectious defect. MethodsBetween June 2008 and October 2012, 22 cases of tibial large segment defect were treated. There were 15 males and 7 females, aged 24-58 years (mean, 36.8 years), including 17 cases of postoperative nonunion or malunion healing, and 5 cases of large defect. After debridement, bone defect size was 5.0-12.5 cm (mean, 8.05 cm). Bone transportation was performed by ring type external fixator combined with locked intramedullary nail, the mean indwelling duration of external fixation was 10.2 months (range, 2-26 months); the external fixation index was 1.57 months/cm (range, 0.3-3.2 months/cm); and the mean length increase was 8.05 cm (range, 5.0-12.5 cm). ResultsAll patients were followed up 19-58 months (mean, 32 months). No infection occurred after operation and all patients obtained bony union, and the union time was 4.7-19.4 months (mean, 11.9 months). Complications included refracture (1 case), skin crease (1 case), lengthening failure (1 case), foot drop (2 cases), retractions of the transport segment (1 case), delay of mineralization (1 case), which were cured after corresponding treatment. According to Hohl knee evaluation system to assess knee joint function after removal of external fixator and intramedullary nail, the results were excellent in 15 cases, good in 5 cases, and fair in 2 cases, with an excellent and good rate of 90.9%; according to Baird-Jackson ankle evaluation system to evaluate ankle joint function, the results were excellent in 10 cases, good in 3 cases, fair in 7 cases, and poor in 2 cases, with an excellent and good rate of 59.1%. ConclusionBone transportation by ring type external fixator combined with locked intramedullary nail could increase stability of extremities, allow early removal of external fixator and avoid axis shift of extremities, so it has good effect in treating tibial noninfectious defect.
ObjectiveTo provide the anatomical basis for the selection of osteotomy site in leg lengthening or tibial slip. MethodsBetween August 2010 and July 2014, 10 adult fresh amputated leg specimens were collected. The pressure perfusion of red latex was performed by the popliteal artery. The anterior tibial artery and its main branches were separated and exposed, and the periosteal branch of anterior tibial artery was adequately exposed;the posterior tibial artery and its main branches were exposed;the peroneal artery was separated and exposed. The tibial and peroneal artery and its branches were observed and measured. When measuring the proximal end, the medial tibial plateau bone margin, the most prominent part of the tibial tuberosity, and the fibular head edge were used as a reference;when measuring the distal end, distal medial condyle of tibia malleolus tip, tibial lateral malleolus lateral tip, and distal tibial articular surface were used as a reference;the vertical distance between tibia proximal and distal main arteries and bone end reference was measured to determine the optimal osteotomy position of upper and lower tibia. The osteotomy index was calculated which was used to represent the relative position of osteotomy site in the whole tibia. ResultsThe proximal tibial osteotomy site located at (78.2±19.5) mm from medial tibial plateau margin, (41.8±16.0) mm from the tibial tuberosity pole, and (66.7±16.4) mm from the fibular head edge. The distal tibial osteotomy site located at (70.8±12.1) mm above the inferior margin of tibial medial malleolus, (83.3±13.0) mm above the inferior margin of lateral malleolus tip, and (59.1±11.7) mm from distal tibial articular surface. The proximal tibial osteotomy index was 18.45-23.35 (mean, 20.46);the distal tibial osteotomy index was 14.36-23.05 (mean, 18.81). ConclusionThe metaphyseal-diaphyseal connection shold be selected in the proximal and distal tibia osteotomy, the lower one third of the tibia is not suitable for ostetomy.
ObjectiveTo evaluate the risk factors for central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC) of cN0 staging. MethodsClinical data of 94 patients with cN0 PTC in Guangdong General Hospital who underwent thyroidectomy with prophylactic central node dissection (pCND) from March to July in 2014 were collected to analyze the risk factors of CLNM by using univariate and multivariate analysis methods. ResultsCLNM was found in 43 patients (45.7%). Multivariate analysis results showed that, the CLNM rate of patients with age < 45 years, tumor located in front of lobe by ultrasound, diameter of tumor > 2 cm, capsular invasion, and total number of central lymph node dissected > 3 were significantly higher (P < 0.05). ConclusionAge < 45 years, tumor located in front of lobe by ultrasound, and diameter of tumor > 2 cm are the risk factors of CLNM in patients with cN0 PTC, pCND should be performed for patients with some of the above risk factors.
ObjectiveTo study the effectiveness of transverse carpal ligament release for carpal tunnel syndrome (CTS) with arthroscopic "two-portal" technique under local anesthesia. MethodsTransverse carpal ligament was released with arthroscopic "two-portal" technique in 31 patients with CTS between November 2002 and August 2008. There were 4 males and 27 females, aged 24-71 years (mean, 52 years). The disease duration was 1 month to 14 years (mean, 42 months). According to the guidelines of Bin Tian, 20 sides were rated as grade I, 16 sides as grade Ⅱ, and 5 sides as grade Ⅲ before operation. The sensation was S2+ in 7 cases, S3 in 19 cases, and S3+ in 5 cases. The muscle strength of the abductor pollicis brevis and opponens pollicis muscles was grade 2 in 5 cases, grade 3 in 14 cases, and grade 4 in 7 cases. Michigan hand function scoring system (MHQ) was used to evaluate the function of the hand before and after operation. ResultsAll incisions healed primarily, and no complications of median nerve injury and adhesion occurred. All of the 31 patients were followed up 6-11.8 years (mean, 9.6 years). After operation, numbness and paresthesia of fingers were relieved (S4); the muscle power returned to grade 4 in 8 cases, and to grade 5 in 23 cases. The MHQ scores of function, daily life, work, pain, appearance, and satisfaction were improved significantly at 6 months postoperatively when compared with preoperative ones (P<0.05). There was no relapse. ConclusionArthroscopic "two-portal" technique is an effective surgical procedure for relieving the compression symptoms on the median nerve from carpal canal, so it is helpful to functional recovery of the median nerve. The long-term effectiveness is definite.
