This paper introduces the technical features of hydrosurgery system and evaluates it from three aspects:safety and effectiveness, economy and technology maturity. The evaluation results show that the safety and effectiveness are high, and the safety mainly involves the misuse of the system, which cause the adverse events. A large number of literatures have proved that the system is more suitable for the debridement of fine parts. It is estimated that hydrosurgery system has better economic performance, but the cost and patients' cost is also increased correspondingly. In the aspect of technology maturity assessment, this technology is a patented technology, and the number of published papers both at home and abroad is on the rise, indicating that the initial application of the technology is better and the technology is in infancy stage. Therefore, hydrosurgery system has certain advantages in all aspects. Hospitals need to allocate the equipment according to their own needs and clinical application, while a wider range of clinical trials is needed to provide evidence-based evidence for clinical applications and promotion.

PURPOSE: The success rate of endoscopic dacryocystorhinostomy has been increasing with the development of better instruments and techniques. We conducted this study to evaluate the clinical results of endoscopic dacryocystorhinostomy using a Microdebrider, which has also been used for functional endoscopic sinus surgery. METHODS: We selected 76 patients (with a total of 84 affected eyes) who had been diagnosed with a nasolacrimal duct obstruction. These patients underwent an endoscopic dacryocystorhinostomy using a Microdebrider, which removed both nasal mucosa and lacrimal sac mucosa and also trimmed the margins of the ostotomy site. We assessed patients' outcomes on an anatomical basis using a dye test and endoscopy, which were used to define the anatomical success. We also arbitrarily defined functional success as whether the subjective epiphora was absent. At a four to 18 month follow-up, we monitored the clinical course to examine any recurrent episodes. RESULTS: The symptoms were alleviated in 72 eyes, with a primary success rate of 85.7%. On nasal endoscopy, a functional failure was seen in four eyes. In these four eyes, the orifice was narrowed by the presence of either granulation tissue or conjunctivochalasis. By contrast, surgical outcomes were the anatomical failure in eight eyes. In these eight eyes, the orifice was obstructed by the presence of granulation tissue as well as the adhesion of nasal mucosa. CONCLUSIONS: Endoscopic dacryocystorhinostomy using a Microdebrider enabled us to make the large fistula while minimizing the damage of adjacent tissue. It might be the recommended surgery that reduces the complications and enhances the success rate.

OBJECTIVETo evaluate the clinical effect of eschar grinding and wound coverage by biological dressing A in the management of deep partial-thickness burn wound on the extremities.

METHODSSeventy-three patients with deep partial-thickness burns on the extremities were divided into two groups to receive different managements. The patients in group 1 were treated with eschar grinding and wound coverage with biological dressing A, and group 2 received conventional treatment. The white blood cell count, body temperature, incidence of wound infection and wound healing time were observed.

RESULTSCompared with conventional treatment, wound management with eschar grinding and coverage by biological dressing A could increase the effective rate (29/32 vs 31/41, P<0.05), inhibit systemic inflammation and scar hypertrophy, and shorten the wound healing time (13.79-/+5.72 vs 17.08-/+8.39, P<0.01).

CONCLUSIONEschar grinding and wound coverage by biological dressing A can be effective for management of deep partial-thickness burns on the extremities, and earlier treatment with the dressing A achieves better effect.

OBJECTIVETo investigate the effectiveness of anterior debridement,bone graft, and posterior pedicle screw-rod internal fixation in the treatment of lumbosacral tuberculosis.

METHODSFrom January 2005 to June 2012,18 patients with lumbosacral tuberculosis undergoing the surgical treatment by anterior debridement, bone graft, and posterior pedicle screw-rod internal fixation were reviewed retrospectively. There were 12 males and 6 females with an average age of 44 years old ranging from 35 to 67. Among them, 2 cases were simple low back pain,3 cases were low back pain combined with radiating pain of lower extremity and 13 cases were muscle strength hypesthesia. According to Fankle grading,the nerve function was grade C in 3 cases,grade D in 10 cases,grade E in 5 cases. Of these cases,L4.5 was involved in 8 cases,L5 in 4 cases and L5S1 in 6 cases. The lumbosacral angle was 150 to 270 and the erythrocyte sedimentation rate (ESR) was 45 to 93 mm/h before treatment. The clinical indexes including the lumbosacral incidence, Frankel grade and ESR were reviewed at follow-up.

RESULTSAll 18 cases were followed up for 14 to 22 months. The mean operation time was 180 min. The amount of bleeding was 400 to 800 ml. Except 1 case with iliac vein injuried and 4 cases with abdominal distension,no spinal injuries and severe relative complication occurred, and neurologic function improved in various degrees. Pain in lumbosacral area and radicular pain in lower extremities disappeared. The X-ray and CT films demonstrated that bony fusion was obtained in all patients during 9 to 13 months postoperatively. The lumbosacral angle and ESR were improved significantly.

CONCLUSIONAnterior debridement, bone graft, and posterior pedicle screw-rod internal fixation is an effective method in dealing with lumbosacral spine tuberculosis.

OBJECTIVE: To explore the efficacy of callus distraction performed by external fixtor in the reconstruction of bone defect and leg shortening of femur after osteomyelitis. METHODS: Nineteen child patients with bone defect and leg shortening after ostemomyelitis were treated by callus distraction with external fixator. The mean length of the bone defect was 1.3 cm. The mean leg-length discrepancy was 4.8 cm. RESULTS: All patients were followed up for 21-82 months. The bone lengthening area grew well, the length of callus distraction was 4.5-8.0 cm, and the mean radiographic consolidation index was 39.7 d/cm. According to the Paley's criteria, the healing effect of 14 cases was excellent, and that of the rest 5 cases was good. The functional recovery of 11 cases was excellent, and that of the rest 8 cases was good. CONCLUSION Callus distraction is a reliable method in the reconstruction of bone defect and leg shortening caused by ostemomyelitis.
