This study aimed to evaluate the feasibility and effectiveness of closing the small bowel in an ex vivo porcine model with high-frequency welding device. A total of 100 porcine small bowels were divided into two groups, and then were closed with two different methods. The fifty small bowels in experimental group were closed by the high-frequency welding device, and the other fifty small bowels in comparison group were hand-sutured. All the small bowels were subjected to leak pressure testing later on. The speed of closure and bursting pressure were compared. The 50 porcine small bowels closed by the high-frequency welding device showed a success rate of 100%. Compared with the hand-sutured group, the bursting pressures of the former were significantly lower (P<0.01) and the closing process was significantly shorter (P<0.01). The pathological changes of the closed ends mainly presented as acute thermal and pressure induced injury. Experimental results show that the high-frequency welding device has higher feasibility in closing the small bowel.

Medial patellofemoral ligament (MPFL) is the major static structure to restrain lateral patellar dislocation. There are always MPFL injuries in patellar dislocations. The medial ligamentous deficiency will lead to recurrent patellar dislocation or patellar instability. Surgeon used to suture all those structures in the medial knee compartment before MPFL is recognized. Reconstruction of MPFL becomes an important method to treat patellar dislocation since it is anatomically recognized. Many techniques have invented MPFL reconstruction. The goal of this article is to develop a current understanding of MPFL and its clinical significance, especially MPFL reconstruction. The anatomical double bundle reconstruction of MPFL by bone anchors is a safe, easy and effective way to treat patellar dislocations.

OBJECTIVETo probe the possibility of a new technique of primary cleft palate repair by sutural distraction osteogenesis.

METHODSThe distractor was made of TiNi-shape memory alloy with 2 secure and 2 active arms. Under general anesthesia, 1 hole was drilled on each maxillary process and horizontal plate of palatine. The four arms of the distractor were inserted into holes. The palatine bones would then be distracted and moved medially and posteriorly. After 4 to 5 months' distraction, the two cleft edges approached gradually. The residual cleft, according to its width, was repaired by direct stitch of muco-periosteum incised at cleft edges, or with an additional relaxing incision on one side of the palate. Direct measurement of width of maxillary arch and the cleft, and the length of the hard palate was performed before and after distraction to evaluate the effects of distraction.

RESULTSEight cleft children at their 2 to 4 years of age were treated by the new technique. Two of them terminated the procedure due to premature dislocation of the distractor. Six children underwent 37 to 126 days' distraction. Dramatic narrowing of the cleft and lengthening of hard palate were seen in these children, with the average narrowing of the cleft being 6.5 mm and average lengthening of the hard palate being 4.8 mm.

CONCLUSIONIt is clinically demonstrated that palatal tissue regeneration and cleft closure or narrowing and hard palate lengthening could be achieved by the technique of sutural distraction osteogenesis.

OBJECTIVETo determine the safety and efficacy of total percutaneous endovascular abdominal aortic aneurysm repair using the Perclose ProGlide suture-mediated closure system.

METHODSFrom May 2008 to April 2010, 36 abdominal aortic aneurysm patients were undergone total percutaneous endovascular repair. There were 30 male and 6 female patients with a mean age of 68 years. Endografts used included 3 Endurant endografts, 13 Talent endografts, and 20 Zenith endografts. Prior to insertion of the introducer sheath, two ProGlides were pre-set to 18 to 24 F access sites and one to 14 to 16 F access sites. At last, suture the arteriotomy by tying down knots of the ProGlide following removal of the sheath. Technical success, complications, and procedure and access closure times were evaluated. Follow-up protocol consisted of computed tomography angiograms performed at 3, 6, 9, 12 months, and annually thereafter.

RESULTSTwenty patients were operated under local anesthesia and 16 patients under general anesthesia. A total of 68 femoral arteries were closed with 128 devices. Thirty-eight vessels were with 2 devices, while 8 arteries required 3 devices and 2 arteries required 4 devices for hemostasis and an additional 20 vessels only required a single device. Sixty-three (63/68, 92.6%) vessels were closed successfully. Two vessels converted to open closure. Three vessels complicated with hematomas without surgical procedure. The mean follow-up was (12±3) months. There was one asymptomatic femoral artery dissection 3 months after operation.

CONCLUSIONSTotal percutaneous endovascular abdominal aortic aneurysm repair is safe and effective. But it should be performed at hybrid operating room where can convert to open procedure if necessary.

OBJECTIVETo study the clinical effects of Achillon for the treatment of acute Achilles tendon rupture (AATR).

METHODSFrom April 2009 to April 2010, 19 patients with AATR who were treated with Achillon were retrospectively analyzed. There were 17 males and 2 females, with an average age of 40.2 years (30 to 58 years). There were 9 cases of sports injury, and 2 case of fall injury. The time from injury to surgery ranged from 0 to 8 days (2.2 days on average). The results of Thompson test and single heel rise test were positive in 19 cases. Clinical data were assessed with the patient satisfaction and the AOFAS hindfoot score during follow-up.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 28 months (19.9 months on average). The average operation time was 41 minutes. There were no wound infections, recurrent rupture, or sural nerve complications. At the latest follow-up, 18 patients were totally satisfied with the surgical result, 1 patient feel generally due to mild pain when running. None of the patients were dissatisfied with the final results the latest follow-up. At the latest follow-up, the AOFAS score was 98.42 +/- 3.29 (89 to 100). All the patients regained normal range of motion and were able to resume their previous activities at six months after operation, with a high rate of satisfaction. Average decreased of mid-calf circumference was (0.82 +/- 0.85) cm (ranged from 0 to 3 cm).

CONCLUSIONTreatment with Achillon is safe, effective for AATR with low incidence of complications and early active rehabilitation can be carried out. It is a good method to treat AATR.

OBJECTIVETo improve the methods and reduce the complications of circumcision with a disposable suture device.

METHODSThis study included 325 male patients aged 14-65 (mean 28.9) years, treated for redundant prepuce or phimosis by modified (n = 201) or conventional circumcision with a disposable suture device (n = 124). We compared the incidence of complications and the patients' satisfaction between the two surgical methods.

RESULTSCompared with conventional circumcision, the modified method showed a significantly lower incidence of postoperative bleeding (14.52% vs 2.49% , P < 0.05) and a lower rate of second surgery for penile hematoma (4.03% vs 0.50%, P < 0.05). The patients' satisfaction was markedly higher with the modified method (91.94%) than with conventional circumcision (97.51%) (P < 0.05).

CONCLUSIONModified circumcision with the disposable suture device can significantly reduce the incidence of postoperative bleeding and penile hematoma and therefore deserves wide clinical application.

ObjectiveTo investigate the clinical effects of circumcision by surgical plane positioning with a disposable circumcision suture device in the treatment of phimosis and redundant prepuce.

METHODSFrom September 2016 to June 2017, we treated 250 patients with phimosis or redundant prepuce, 127 by conventional circumcision (the control group) and the other 123 by surgical plane positioning with a disposable circumcision suture device (the observation group). We compared the operation time, intra-operative bleeding, preputial frenulum alignment, postoperative ecchymosis, and postoperative penile appearance between the two groups of patients.

RESULTSCompared with the controls, the patients in the observation group showed significantly longer operation time (［4.48 ± 1.18］ vs ［7.17 ± 1.42］ min, P<0.05), lower rates of intra-operative frenulum bleeding (15.0% ［19/127］ vs 4.1% ［5/123］, P<0.05) and frenulum misalignment (26.8% ［34/127］ vs 0.8% ［1/123］, P<0.05), higher incidence of postoperative ecchymosis (41.7% ［53/127］ vs 21.1% ［26/123］, P<0.05), and higher satisfaction of the patients with the postoperative penile appearance (92.9% ［18/127］ vs 98.4% ［121/123］, P<0.05). However, no statistically significant difference was found between the control and observation groups in intra-operative non-frenulum bleeding (4.7% ［6/127］ vs 1.6% ［2/123］, P = 0.164).

CONCLUSIONSCircumcision by surgical plane positioning with a disposable circumcision suture device can effectively avoid preputial frenulum misalignment, reduce intra-operative bleeding, and improve postoperative penile appearance.

Objective: To investigate the effect of the frenulum identification positioning method with a disposable suture device in circumcision for the prevention of postoperative penile frenulum malposition. METHODS: Totally 212 patients with phimosis or redundant prepuce underwent circumcision from March 2015 to September 2016, including 109 cases of conventional circumcision (the control group) and 103 cases treated by frenulum identification positioning with a disposable suture device (the observation group). We observed the postoperative position of the penile frenulum and median raphe and compared the deviation angles of the frenulum between the two groups of patients. RESULTS: The median of penile frenulum deviation angle (interquartile range) was 0 (3.56) in the observation group, significantly smaller than 12.41 (19.59) in the control (P <0.001, P = 0.000). And the rate of frenulum deviation was remarkably lower in the former (8.74% ［9/103］) than in the latter group (66.06% ［72/109］) (P <0.01). CONCLUSIONS Circumcision using the frenulum identification positioning method with a disposable suture device can effectively avoid postoperative penile frenulum malposition. With the advantages of safety and easy operation, it deserves clinical application and popularization.

BACKGROUNDThe biofragmentable anastomosis ring (BAR) is a simple alternative device to create intestinal anastomosis. Our study was designed to evaluate the clinical value of BAR in intestinal anastomosis.

METHODSA total of 167 patients performed intestinal anastomosis from January 2002 to February 2006 were randomized to BAR group (n = 82) and manual suture group (n = 85) as control. They were equally allocated to the two groups regarding sex, age, site of anastomosis, emergent or elective surgery and contaminant diseases. The results of postoperative complications and recovery were recorded in each group.

RESULTSEighty-seven intraperitoneal BAR anastomoses were completed in 82 patients. Two and one postoperative deaths were recorded in BAR and suture group, respectively, no deaths were directly related to anastomotic technique. In suture group, anastomotic leakage and early bleeding both occurred in two patients respectively, no anastomotic bleeding occurred in BAR group, one patient in BAR group developed enterocutaneous fistulae. Perioperative bleeding, operation time and length of hospitalization were similar in two groups (P > 0.05). Time for return of bowel function was significantly shortened in BAR group than that in suture group (P < 0.05).

CONCLUSIONThe BAR appears to be a standard, easy, safe and effective alternative either in elective or emergent intraperitoneal intestinal anastomotic surgery.
