Clinical application of the disposable circumcision suture device in male circumcision / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the safety and efficiency of the disposable circumcision suture device (DCSD) in the surgical treatment of phimosis and redundant prepuce.</p><p><b>METHODS</b>We randomly assigned 249 outpatients with phimosis or redundant prepuce to be treated with DCSD (n = 129) and by conventional circumcision (CC, n = 120), respectively. Then we compared the safety and efficiency of the two strategies.</p><p><b>RESULTS</b>Comparisons between DCSD and CC showed that the operation time was (4.02 +/- 0.69) vs (30.8 +/- 4.05) min, blood loss was (1.07 +/- 1.29) vs (8.72 +/- 2.15) ml, intraoperative pain score was 0.81 +/- 0.81 vs 2.42 +/- 1.15, 24-hour postoperative pain score was 1.84 +/- 1.02 vs 4.99 +/- 1.36, postoperative complication rate was 13. 95% (18/129) vs 9.17% (11/120), wound healing time was (13.99 +/- 9.06) vs (17.48 +/- 3.49) d, satisfaction with the penile appearance was 98.4% (127/129) vs 95% (109/120), and treatment cost was (2215.62 +/- 17.67) vs (576.47 + 15.58) Y RMB. DCSD exhibited obvious superiority over CC for shorter operation time, less blood loss, milder intraoperative pain, sooner wound healing, and better penile appearance, but it also had a higher rate of postoperative complications (P > 0.05) and involved more treatment cost than the latter (P < 0.05).</p><p><b>CONCLUSION</b>The disposable circumcision suture device affords ideal clinical effects and therefore deserves clinical popularization.</p>

Arthroscopic release with radiofrequency vaporization for knee joint stiffness / 中华创伤杂志

Objective To evaluate the advantages and short term clinical results of arthroscopic release with radiofrequeney vaporization for knee joint stiffness.Methods Arthroscopic release with ra- diofrequency vaporization was done in 32 cases with knee joint stiffness resulted from various causes be- tween January 2002 and June 2005.According to degree of stiffness,32 cases were divided into three groups,ie,Group A(18 cases with suprapatellar bursa adhesions)treated with confectioning at suprapa- tellar bursa and lateral grooves;Group B(eight cases with joint compartment adhesions)managed with debridement at suprapatellar bursa and lateral groove and intereondyloid fossa,bending the knee with pressure and abscising the adhesion part in the joint compartment with radiofrequency vaporization;and Group C(six cases with most part of the joint adhered)treated by making small incision at the lateral or medial upper pole of the patellar as well as a space at the suprapatellar bursa by blunt dissection when it was difficult to insert arthroscope.After that,release combined with massage manipulation and thorough hemostasis by radiofrequency vaporization were carried out.There was no drainage after operation.Pas- sive and active flexion and extension exercises with pressure began two days after operation.Results Pre-operative limitation of flexion was 35?-75?that was increased to 115?-125?three weeks after opera- tion,with mean improvement of 78?in Group A.Pre-operative limitation of flexion was 40?-60?that was increased to 95?-120?three weeks after operation,with mean improvement of 72?in Group B.Pre-opera- tive limitation of flexion was 25?-45?that was increased to 90?-110?three weeks after operation,with mean improvement of 64?in Group C.No haematocele occurred postoperatively,with only slight swelling of the knee.Conclusion Arthroscopic release with radiofrequency vaporization for knee joint stiffness is characterized by less bleeding,minor trauma and reliable release and can be applicable especially for the eases with only adhesion at suprapatellar bursa,lateral groove or joint compartment.
