Postoperative patients' risk for developing venous thromboembolism (VTE) can be predicted using the adapted Caprini risk assessment model which informs administration of postoperative VTE prophylaxis. The study aimed to assess the appropriateness of postoperative VTE prophylaxis of patients according to the adapted Caprini scores and investigate whether a patient's HIV status influenced postoperative VTE prophylaxis administration. This cohort study included patients who had elective or urgent surgery at a tertiary hospital, Bloemfontein. Data from patient files were captured on datasheets that comprised the adapted Caprini risk assessment model. The type of prophylaxis received was noted. The appropriateness of the prophylaxis prescribed was compared with the patient's score. Details of 147 patients were included. Three of the 16 patients who did not qualify for prophylaxis, were on VTE prophylaxis on day-one post-surgery. Only 24 (18.3%) of the 131 patients who qualified for prophylaxis were on prophylaxis one day post-surgery. Of the prophylaxis prescribed, 88.5% was enoxaparin, and 11.5% "other", mainly aspirin. Twenty-three (17.6%) patients who qualified for prophylaxis were discharged on prophylaxis. Of the 147 patients, 24 patients were HIV positive, and eight of these patients received postoperative VTE prophylaxis. The majority of postoperative patients at the various surgical departments of the hospital did not receive appropriate postoperative VTE prophylaxis compared to the adapted Caprini scores obtained from their medical information. A patient's HIV status alone did not influence the decision of administering postoperative VTE prophylaxis.
Ureteral stenting is generally a theatre-based procedure that requires a multidisciplinary team and on-table imaging. Limited hospital bed numbers and theatre time in our centre in Cape Town, South Africa, have led us to explore an alternative approach.To see whether outpatient insertion of ureteric stents under local anaesthesia without fluoroscopy was a possible and acceptable alternative to theatre-based ureteral stenting.Ureteral stenting (double-J stents and ureteric catheters) was performed with flexible cystoscopy under local anaesthesia and chemoprophylaxis, but without fluoroscopic guidance, in an outpatient setting. Every patient had an abdominal radiograph and an ultrasound scan of the kidney after the procedure to confirm stent position.Three hundred and sixteen procedures (276 double-J stents and 40 ureteric catheters) were performed in 161 men and 155 women. The overall success rate for the procedures was 85.4%, independent of gender (p=0.87), age (p=0.13), type of device inserted (p=0.81) or unilateral/bilateral nature of the procedure (p=1.0). Procedures with a successful outcome were performed in a significantly (p<0.0001) shorter median time (10 minutes (interquartile range (IQR) 5 - 15)) than failed procedures (20 minutes (IQR 10 - 30)). Patients with a pain score of >5 experienced a significantly (p=0.02) greater proportion of failure (27.3%) than patients with a pain score of ≤5 (12.5%). Difficulties were encountered in 23.7% of procedures, with a significantly higher proportion being registered in failed interventions compared with successful ones (82.6% v. 13.7%; p<0.0001).The procedure was easily mastered and technically simple, and represents savings in cost, time and human resources in our setting.
The role of nonoperative management for penetrating kidney injuries is unknown. Therefore, we review the management and outcome of penetrating kidney injuries at a center with a high incidence of penetrating trauma.Data from all patients presenting with hematuria and/or kidney injury discovered on imaging or at surgery admitted to the trauma center at Groote Schuur Hospital in Cape Town, South Africa during a 19-month period (January 2007 to July 2008) were prospectively collected and reviewed. These data were analyzed for demographics, injury mechanism, perioperative management, nephrectomy rate and nonoperative success. Patients presenting with hematuria and with an acute abdomen underwent a single shot excretory urogram. Those presenting with hematuria without an indication for laparotomy underwent computerized tomography with contrast material.A total of 92 patients presented with hematuria following penetrating abdominal trauma. There were 75 (80.4%) proven renal injuries. Of the patients 84 were men and the median age was 26 years (range 14 to 51). There were 50 stab wounds and 42 gunshot renal injuries. Imaging modalities included computerized tomography in 60 cases and single shot excretory urography in 18. There were 9 patients brought directly to the operating room without further imaging. A total of 47 patients with 49 proven renal injuries were treated nonoperatively. In this group 4 patients presented with delayed hematuria, of whom 1 had a normal angiogram and 3 underwent successful angioembolization of arteriovenous fistula (2) and false aneurysm (1). All nonoperatively managed renal injuries were successfully treated without surgery. There were 18 nephrectomies performed for uncontrollable bleeding (11), hilar injuries (2) and shattered kidney (3). Post-nephrectomy complications included 1 infected renal bed hematoma requiring percutaneous drainage. Of the injuries found at laparotomy 12 were not explored, 2 were drained and 5 were treated with renorrhaphy.Penetrating trauma is associated with a high nephrectomy rate (24.3%). However, a high nonoperative success rate (100%) is achievable with minimal morbidity (9%).
AimTo determine the preferable treatment for congenital pseudarthrosis of the tibia, we retrospectively reviewed 19 patients (20 limbs) treated consecutively over a 22 year period (1988–2007). Fifteen were followed up to maturity. The patients were assessed for union, leg length discrepancy (LLD), ankle valgus, range of ankle movement and distal tibial physeal injury.ResultsThe median age at surgery was 3 years. At surgery nineteen of the tibiae had a dysplastic constriction with a fracture (Crawford II-C or Boyd II) lesion.To obtain union in the 20 tibiae, 29 procedures were done. Nine failed primarily and required a second procedure to obtain union. Older patients (≥ 5 years) had a significantly higher success rate.Excision, intramedullary rodding and bone graft (IMR) was done in 14 tibiae: 10 (71.4%) were successful. Six of 10 primary operations and all 4 secondary operations after a previous failed procedure were successful.Ipsilateral vascularized fibula transfer (IVFT) was successful in 5 tibiae (3 ...
