Objective To propose the cause and management of necrosis in reversed island flap or distally-pedicled flap. Methods From June 2000 to June 2009, 120 cases with skin and soft tissue defect were repaired using reversed island flap or distally-pedicled flap. In 12 cases the flaps partial necrosis, to analysis the cause of necrosis. Results One hundred and eight cases survived completely in 120 patients,flap necrosis in 12 cases. 3 cases fully necrosis, in which venous disorders cause flap necrosis in 2 cases, arterial blood disorder caused necrosis of flap in 1 case. Partial necrosis in 9 cases, in which dorsal metacarpal artery reversed island flap in 1 case, digital artery reversed island flap in 1 case, posterior tibial artery reversed island flap ankle epithelial branch in 4 cases, medial leg perforating branches of reversed island flap in 1 case, superficial peroneal nerve vascular reversed island flap island flap in 1 case, distally-pedicled based sural neurocutaneous flap in 1 case, after debridement and dressing change subeschar healed in 7 cases, by the other flaps were cut close to rerepair necrotic wounds in 2 cases. Conclusion Blood circulation barrier is the main reason to flap necrosis, improper handling of pedicle is another important reason of flap necrosis,which cannot be ignored.
8.Present status and existing problems of laparoscopic surgery for malignant gastrointestinal cancer
Chinese Journal of Digestive Surgery 2008;7(3):161-163
Laparoscopic surgery has gained wide acceptance for its use in benign gastrointestinal cancer in the past 20 years, while its use in malignant gastrointestinal cancer has been highly controversial until the recent 3-5 years. Several prospective randomized clinical trials have suggested that the long-term outcome of laparoscopic surgery for colon cancer is the same as or better than that of open surgery. As for rectal cancer, whether the principles of total mesorectal excision can be well followed in laparoscopic surgery remains. Most recently, the trial of large number of patients doesn't show any differences upon local recurrence and 3-year survival rate between rectal cancer patients in laparoscopic group and open group. Laparoscopic surgery has been widely accepted as a standard treatment regimen for early gastric cancer in many specialized centers. Meanwhile, the feasibility and effectiveness of laparoscopic D2 lymphadenectomy for gastric cancer has been proved by several scholars. The use of laparoscopic surgery for advanced gastric cancer especially for T3 gastric cancer still remains controversial. The early concern that laparoscopic surgery for malignant cancer might increase tumor dissemination is not confirmed. The system of technical training and occupational qualification, proper selection of patients and adherence to all the principles of cancer clearance will ensure a good result of laparoscopic surgery for malignant gastrointestinal cancer.
9.Changes of flexor-extensor strength during trunk isokinetic exercise: Angle ranges easily lead to spinal injury
Chinese Journal of Tissue Engineering Research 2010;14(7):1191-1195
BACKGROUND: Studies concerning trunk muscles mainly focus on muscle strength changes in patients with low back pain,which is rare regarding angle ranges that easily lead,to spinal injury.OBJECTIVE: To explore the mechanics characteristic of flexor-extensor and angle ranges easily lead to spinal injury. METHODS: Fourteen healthy, male, post-graduates of Soochow University were selected. Flexor-extensor strength and spinal angle of participants were measured using CON-TREX isokinetic testing system. All participants took isokinetic centrifugal exercise maximally at the speeds of 30, 60, 90, 120, 180 (°)/s, respectively, with a 5 minutes interval. Main outcome measures:①Lumbar range of motion; ②Peak torque, flexor/extensor, the angle at peak torque at isokinetic centripetal exercise; ③Average power and total work at isokinetic centripetal exercise.RESULTS AND CONCLUSION: ①During isokinetic centripetal exercise, the peak torque of extensor were decreased as the geniovelocity increased (P < 0.05), however, no inerratic changes could be found in flexor peak torque. Though the flexor/extensor was increased with geniovelocity increased, the difference had no significance (P > 0.05). ②Dudng slow isokinetic centripetal exercise underwent different geniovelocity, the angle at peak torque of flexor and extensor distributed discretely, -48.56° at 30 (°)/s; -46.18° at 90 (°)/s; when underwent fast isokinetic exercise, the angles at peak torque of flexor and extensor were very close, which were -48.71° and -51.61° at 120 (°)/s, and -54.86° and -53.11° at 180 (°)/s. ③During isokinetic centripetal exercise, when underwent different geniovelocity, total work of flexor and extensor was reduced with geniovelocity expedited, extensor total work was more than that of flexor (P < 0.05); the average power of flexor and extensor was increased linearly with geniovelocity expedited, and the average power of flexor was less than that of extensor all along (P < 0.01). During isokinetic centripetal exercise, trunk muscle strength descended with the geniovelocity expedited, and the stability of trunk is preferable in slow exercise. During fast isokinetic centripetal exercise, angles at flexor and extensor peak torque are more discrete, which easily result in muscle damages and spine unstable when suffered a suddenly outside attack. Total work of flexor and extensor are descended with the geniovelocity expediting during isokinetic exercise, but the intramuscular eruption increased.
