Inner fistula by abdomino-back anastomosis of cephalic vein to radial artery was erformed in 86 patients with hemodialysis (test group) and end-to side arteriovenous anastomosis was performed in 85 cases (control group).There were no significant differences in postoperative anastomotic blood flow and vascular complications between two groups (P ＞ 0.05);however the average time consuming for operation in test group was shorter than that in control group (36 min vs.75 min,P ＜ 0.01).The minimally invasive abdomino-back anastomosis is a desired arteriovenous fistula method for hemodialysis patients.

The blood vessels, nerves and the size of the gracilis muscle were studied in 50 adult Chinese cadavers (43 males and 7 females).In average, the length of the gracilis muscles is 325 mm the breadth is 26.18mm the thickness is 6.56mm. The length of its tendon is 112.78 mm.The nutrient arteries of the gracilis muscle may arise from the profund femoral artery, medial circumflex femoral artery, the first perforating artery, femoral artery, popliteal artery, supreme genicular artery or obturator artery. Among them, the profund femoral artery and femoral artery give off constant branches to the gracilis muscle.The dominant nutrient artery of the gracilis muscle arises from the profund femoral artery in 94 cases (94％), from the medial circumflex femoral artery in 5 cases (5％). There is only one case (1％) arising from the first perforating artery.The average length of the dominant nutrient artery is 83.6mm. Its diameter in the origin is 2.24mm. and outside the hilum, 1.44mm. The distance from the vascular hilum to the pubic tubercle is 142.48mm. The surface respresentation of the dominant neuro-vascular hilum is situated at the junction point of the upper and middle thirds of the line joining the pubic tubercle to the adductor tubercle.There are 72.5％ of the dominant nutrient arteries of the gracilis muscle accompanying with two veins and 27.5％, with only one vein.The gracilis muscle is innervated by the anterior branch of the obturator nerve which accompanies the dominant nutrient artery entering the muscle. Its average diameter is 1.78mm.

The satorius muscle,its blood vessels and nerves have been dissected and examinedin 20 Chinese adult cadavers.It was found,on the average,that the length of thesatorius muscle is 529?8.48mm;the breadth,25.30?0.82mm;and the thickness,10.5?0.66mm.The arteries of the satorius muscle may arise from the surperficial circumflex iliacartery (0.66%?0.46),the femoral artery(58.36%?2.82),the deep femoral artery(3.93?1.11),the lateral circumflex femoral artery and its branches(13.44%?1.95),the supreme genicular artery(20.98%?2.33)and the popliteal artery(2.62%?0.91).There may be 5～13 arterial branches,averaging 7.6,in each satorius muscle,distributing roughly and evenly to the whole muscle,with an interval of about 7cmbetween two adjacent arteries and showing segmental distribution.The upper one third of the satorius muscle is mainly supplied by the branchesof the deep femoral artery and the lateral circumflex femoral artery while theinferior one third,by the branches of the supreme genicular artery.Therefore twoisolated flaps may be planned depending on the arteries mentioned above.The satorius muscle is innervated by the femoral nerve.70% of the cases arewith 1～2 branches of nerves,which,before entering the muscle,may give out 1～7twigs.

Objective To investigate the indications and clinical effect of the low-big hole choledochoduodenostomy. Methods Two hundred and ninty-eight patients, had bile duct stone accompanied with common bile duct lower segment stenosis, were prospectively enrolled into the study and randomly divided into the low-big hole choledochoduodenostomy (improved CD ) group (n = 148 ) and the Roux-en-Y choledochojejunostomy (CJ) group (n = 150). Their perioperative period and long term effect indices were recorded and compared. Results Perioperative period indices:The time of cholangio-jejunostomy was much shorter in improved CD group than the CJ group ([31.0±10.5] min vs [53.0±12.3] min, P＜0.001);The anastomotic leakage was significantly less in improved CD group than the CJ group (2 vs 9, P ＜ 0. 001 ). The long term effect indices: The occurrence of peptic ulcer (3 vs 15 ) and the bile duct cecum or blind loop syndrome (5 vs 158) were significantly lower in group improved CD group than CJ group (Ps＜0.01);The occurrence of bile duct backflow (70 vs 42) was significantly higher in improved CD group than CJ group (P＜0. 0l). Conclusion The clinical effect of the low-big hole choledochoduodenostomy gastrointestinal had excellent effect for bile duct stone accompanied with common bile duct lower segment stenosis, especially for old,weak and critical patients,and it can not be replaced by the Roux-en-Y choledochojejunostomy.

The infection rate was 13.4% (40/300) and 3.1% (9/280) in gallbladder resection, 14.7 % (24/165) and 3.5 % (6/159) in radical operation for carcinoma of colon, 13.6% (15/108) and 3.2% (13/114) in intestine block operation, 9.6% (18/187) and 1.8% (3/169) in stomach resection (P<0.01);The infection rate was 9.3% (13/145)and 2.9% (4/153)in biliary exploration, 14.6% (8/55) and 1.8% (1/56) in WHIPPLE, 10.6% (9/85) and 2.3% (2/88) in cholecystectomy (P<0.05);The infection rate was 6.3% (6/95) and 2.3% (2/86) in liver resection, 5.3% (5/95) and 1.2% (1/87) in spleen resection, 4.6% (3/65) and 1.8% (1/57) in porto-azygos venous disconnection (P>0.05). The wound infection rate of type Ⅰ resection of control group and wound isolation group was 2.0% (6/305) and 1.4% (4/280) (P> 0.05);The infection rate of type Ⅱ and Ⅲ resection was 7.0% (70/995) and 2.9% (28/969), for old man (≥60) was 12.6% (36/286) and 3.6% (10/279), the emergency operation was 10.0% (38/381) and 2.8% (10/362), the operation time ≥3 h was 9.0% (39/435) and 2.8% (12/426), with diabetes was 14.5% (21/145) and 4.9% (6/123), with obesity was 12.3% (40/325) and 3.9% (12/310), with malnutrition was 8.5% (39/458) and 3.2% (14/433), with cancer was 8.6% (40/465) and 3.0% (15/496) (P<0.01).;undergoing unemergency operation was 4.1% (38/919) and 2.5% (22/887),for yong persons (<60) was 3.9% (40/1014) and 2.3% (22/970), with operation time<3 h was (37/865) and 2.4% (20/823), without diabetes was 3.9% (45/1155) and 2.3 % (26/1126), without obesity was 3.7 % (36/975) and 2.1% (20/939), without malnutrition was 4.4% (37/842) and 2.2% (18/816)and without cancer was 4.3% (36/835) and 2.3% (17/753) (P<0.05). Conclu-sions The wound isolation can decrease the wound infection rates by reducing the chance of bacterial contamina-tion.

Objective:To explore the clinical efficacy of internal fixation with a reduction plate assisted by our self-designed lower extremity fracture traction reduction device for tibial plateau fractures of Schatzker type Ⅵ.Methods:A retrospective study was conducted of the 32 patients with tibial plateau fracture of Schatzker type Ⅵ who had been treated at Orthopaedic Department, Mindong Hospital Affiliated to Fujian Medical University from April 2018 to July 2021. Depending on their treatments, they were divided into 2 groups. In the control group of 16 cases subjected to open reduction and internal fixation with manual traction, there were 9 males and 7 females with an age of 50.0±11.7 years; in the observation group of 16 cases subjected to internal fixation with a reduction plate assisted by our self-designed lower extremity fracture traction reduction device, there were 8 males and 8 females with an age of 54.6±11.1 years. The operation time, fracture reduction time, total incision length, intraoperative blood loss, Rasmussen knee function score and maximum active range of knee motion were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability between the groups ( P>0.05). The operation time [(158.6±26.0) min], fracture reduction time [(61.6±9.6) min], and total incision length [16.0 (13.3, 17.0) cm] in the observation group were significantly shorter than those in the control group [(199.9±60.9) min, (73.8±17.2) min, and 20.0 (17.0, 21.8) cm]; the intraoperative blood loss [175.0 (100.0, 200.0) mL] in the observation group was significantly less than that in the control group [200.0 (162.5, 387.5) mL]; the maximum active ranges of knee motion at one week and one month in the observation group were 94.9°±12.0° and 113.8°±14.1°, significantly larger than those in the control group (78.3°±14.6° and 96.8°±11.4°) (all P<0.05). Fractures achieved bony union at one year after operation in both groups. At 12 months after operation, there was no significant difference in the maximum active range of knee motion or the Rasmussen knee function score between the 2 groups ( P>0.05). Conclusion:In the treatment of Schatzker type Ⅵ tibial plateau fractures, compared with manual traction and open reduction, internal fixation with a reduction plate assisted by our self-designed lower extremity fracture traction reduction device can shorten operation time and total incision length, reduce intraoperative blood loss, and facilitate postoperative functional recovery of the knee for the patients.
