    Abstract:
    This paper contains certain proposals for future graft studies. Graft failure should be defined as any occlusion of the graft. Time should be measured from the end of operation to the first occlusion of the graft. The results should be analysed by the Kaplan-Meier estimator, and patency rates should be compared by the log-rank test or Gehan's test. It is stressed that scientifically valid data can only be obtained in prospective, randomized trials.

    OBJECTIVE: To investigate perioperative features and results of surgical treatment of spinal tuberculosis in aged. METHODS: Review the clinical data of 36 aged with spinal tuberculosis from May 1998 to June 2005 retrospectively. The average age was 70.2 years. The sites of infection included 3 cervical, 9 thoracic, 13 thoracolumbar and 11 lumbar. 28 patients suffered 1 or more complications at least and among of them, there were 18 patients have cerebral or heart vascular disease, 16 patients have diabetes mellitus. Before operation, all patients consulted with internal stuff for the proper treatment of concomitant disease. The surgical procedures include: CT guided percutaneous catheter drainage in 3 patients, anterior debridement and bony grafting with anterior instrumentation fixation in 12 patients, anterior debridement and bony grafting with posterior fixation in 5 patients, posterolateral costotransversectomy debridement and interbody fusion with posterior fixation in 7 patients, posterior debridement and posterior fixation in 9 patients. The mean followed-up period was 3 years and 10 months (from 1.5 to 6 years). RESULTS: One died at two week after the operation. Tuberculous infection was controlled in other patients and no recurrence. Two patients died because of myocardial infarction and cerebral hemorrhage respectively at 1.5 and 2.5 years after operation. Bone fusion was achieved in 31 patients. The deformity was partial corrected at the final follow-up. Among 20 cases with neurologic deficit, 11 cases were completely recovered, 5 cases were partly improved. CONCLUSIONS: If the associated disorders and postoperative complications are properly handled, aged patients can endure surgical treatment for spinal tuberculosis. Instrumentation fixation provides adequate stability and promote recovery.

    Early complications directly related to the vascular procedure and which required urgent reoperation occurred in 8% of 628 patients undergoing operations on the arteries of the neck, extremities, and abdomen. The indications for reoperation in this group of 50 patients were recurrent vascular occlusion (29), hemorrhage (13), and bowel ischemia (8). The mortality for those patients not requiring reoperation was 7.5%, but rose to 32% for those patients who did require reoperation. While the risk attending reoperation for abdominal bleeding or bowel ischemia is high (71% and 75%, respectively), these complications are fatal if untreated. Reoperation for occlusion of arteries in the leg carried a low risk (5%), and successful results were obtained 68% of the time.
    Abstract Some 114 patients (median age 52 years) underwent laparoscopic hernia repair as a day-case procedure. Twenty-one patients had bilateral and 11 recurrent hernias. Some 113 patients underwent transabdominal preperitoneal mesh repair but one required conversion to open operation. Mean operating time was 24 min for unilateral and 38 min for bilateral repair. In an operating session of 3·5 h, up to five patients (mean 4·4) underwent surgery and as many as seven hernias were repaired. More than 10 per cent of patients were found to have a previously undiagnosed hernia on the opposite side. A total of 111 patients were discharged home on the day of surgery. Major complications included one omental bleed and one small bowel obstruction. Seroma was the commonest minor complication and occurred in 7 per cent of patients. More than 35 per cent of patients needed no postoperative analgesia. To date there has been one recurrence (follow-up range 2–18 months).

    Objective To investigate the causes, the indications and operative procedures of reoperation for postoperative recurrence of hyperthyroidism. Method Clinical data of 34 cases of postoperative recurrence of hyperthyroidism received reoperation were analyzed retrospectively .Results The reoperative procedures including bilateral subtotal thyroidectomy in 29 cases, unilateral thyroidectomy in 5. All the 34 patients were cured by reoperation.The incidence of postoperative complication was 5.9%,which was not significantly different compared with primary operation treatment during the same time in our hospital.All the 34 case were followed up for 1~10 years,the results showed that all patients were alive well without recurrence or hypothyroidism .Conclusions Extension of the resected thyoid is not enough in the primary surgery is the main cause of postoperative recurrence of hyperthyroidism.Reoperation is the choise of therapy in selective patients with postoperative hyperthyroidsm recurrence .Careful intraoperative dissection can help to avoid injuries of recurrent nerve and parathyroid,and to prevent massive bleeding.

    Incisional hernias develop in up to 11% of surgical abdominal wounds with a possible recurrence following repair of 44%. We describe our experience with a combined fascial and prosthetic mesh repair. Thirty-five patients (16M:19F) have been treated. The original operation was bowel related in 19 cases, gynaecological in 8, hepatopancreaticobiliary in 3 patients, aortic aneurysm repair in 2 and involved a thoraco-laparotomy in 3. The incisions were midline in 26 cases, transverse in 6, paramedian in 2 and rooftop in one patient. The hernias were considered subjectively to be large in 15, medium in 14 and small in 6 of the patients. A proforma was completed for each patient noting intra-operative and post-operative complications, post-operative hospital stay and analgesic requirements. Post-operative complications included seroma formation in 6 patients, deep vein thrombosis in one and a non-fatal pulmonary embolism in another. One patient developed a wound haematoma and one had a superficial wound infection. Post-operative in-hospital stay ranged from 1 to 27 days with a mean of 6.2 days. Of the 35 patients 33 were available for follow-up. Follow-up was for a median of 20.3 months (range 6.0 to 54.1 months). Two of these (6%) patients reported a persistent lump and one (3%) reported persistent pain but none of the remaining 33 was found to have a recurrence. We advocate this technique because it is applicable to all hernias, most of the mesh is behind the rectus sheath and has 2 points of fixation, it is relatively pain-free allowing early mobilisation, has a modest complication rate and a low recurrence rate.
