OBJECTIVE: Laparoscopic adrenalectomy (LA) has become the established procedure for adrenal masses less than 6 cm. The role of LA for large adrenal masses is well defined to a lesser extent. METHODS: Thirty-six LAs were performed in 32 patients (including four patients with single stage bilateral adrenalectomies) over a period of 3 years, from May 2002 to 2005. Patients were divided into two groups based on the tumour size, i.e. masses less than 6 cm (group I) and masses 6 cm or more (group II).The results with respect to mean (95% confidence interval) operative time, blood loss, postoperative course and complications were compared. RESULTS: Group II included 11 LAs performed in 10 patients including one bilateral LA for bilateral phaeochromocytomas in multiple endocrine neoplasia 2A. The mean size (+/-standard deviation) of masses was 8 cm (+/-1.47). In comparison, 22 patients in group I underwent 25 adrenalectomies (including three bilateral single stage procedures for Cushing's syndrome). The mean size of masses was 4.1 cm (+/-1.27). There were eight and six phaeochromocytomas in groups I and II, respectively. By comparing groups I and II, only minimal increase in blood loss and operating time was noted with no significant difference in hospital stay and morbidity. Two cases required conversion to hand assistance towards the end of the procedure in view of their large size. CONCLUSION: LA is the procedure of choice for small adrenal masses but is also feasible for large functioning and nonfunctioning adrenal masses with equally good results. Even bilateral large functioning tumours can be treated safely by LA in a single stage when sufficient experience with the procedure is attained.  相似文献

BACKGROUND: Laparoscopic adrenalectomy (LA) for phaeochromocytoma is a feasible, safe and effective treatment. The effects of associated catecholamine release render LA more challenging, although with comparable morbidity to LA for other diseases of the adrenal gland. METHODS: Data from case records of 44 patients who underwent LAs between May 2002 and May 2006 were analysed retrospectively. The patients were divided into a phaeochromocytoma group (Group I) and a non-phaeochromocytoma group (Group II). The aim of this study was to assess the operative course and outcome of LA in the two groups. RESULTS: The mean operating time and blood loss were slightly higher in LA for phaeochromocytomas compared to LA for other pathologies, but these differences were not statistically significant. The mean hospital stay was 3.84 days in both groups. The phaeochromocytoma group had a slightly higher complication rate of 21% compared to 12%. None of the procedures needed open conversion. A terminal hand assist was employed in two patients in Group I and one patient in Group II. Two patients with bilateral phaeochromocytoma had single stage bilateral LA. CONCLUSION: LA is feasible and effective in phaeochromocytoma. It is associated with a slightly longer operating time, more blood loss and complications when compared with non-phaeochromocytoma masses. LA can be done in a single operation for bilateral masses. Terminal hand assist is a viable and effective option for very large masses.  相似文献

A case-controlled study of the prevalence of genital Chlamydia trachomatis infection in 120 patients with tubal infertility (study group) and 120 clients of the family planning clinic (control group) attending the Ahmadu Bello University Teaching Hospital, Zaria in northern Nigeria is reported. The prevalence was 38.3%, 95% confidence interval (CI) (29.6-47.6%) in the study group and 13.3%, 95% CI (7.8-20.7%) in the control group. There was a fourfold risk of having genital Chlamydial infection among the cases compared to the controls (odds ratio [OR] = 4.04, 95% CI (2.04 < OR < 8.09). Tubal infertility was found to be significantly associated with genital C. trachomatis infection (P < 0.001). Out of the 58 cases of primary infertility, 22(37.9%) tested positive for genital C. trachomatis compared with 24 of the 62 (38.7%) that had secondary infertility. The infection was not found to be significantly associated with a particular type of infertility (primary or secondary), number of sexual partners or previous sexually transmitted disease (P < 0.05). There is need for provision of facilities to enable screening for genital C. trachomatis infection in view of its high prevalence in the study population.  相似文献

There is a significant number of Emergency Department (ED) patients with known chronic hepatitis C virus (HCV) infection who have not been treated with directly acting antivirals. We implemented a pilot ED-based linkage-to-care program to address this need and evaluated the impact of the program using the HCV Care Continuum metrics. Between March 2015 and May 2016, dedicated patient care navigators identified HCV RNA-positive patients in an urban ED and offered expedited appointments with the on-site viral hepatitis clinic. Patient demographics and care continuum outcomes were abstracted from the EMR and analysed to determine significant factors influencing linkage-to-care (LTC) and treatment initiation rates. The ED linkage-to-care program achieved a 43% linkage-to-care rate (165/384), 22% treatment rate (84/384) and 16% sustained virologic response rate (63/384). Significant associations were found between linkage-to-care and increasing age (OR = 1.03), Medicare insurance (OR = 2.21) and having a primary care physician (PCP) (OR = 4.03). For patients who were linked, the odds of initiating treatment were also positively significantly associated with increasing age (OR = 1.04) and having a PCP (OR = 2.77). For patients who initiated treatment, the odds of sustained virologic response were marginally associated with having a PCP (OR = 4.92).Our ED linkage-to-care program utilized care coordination to successfully link nearly half of approached HCV RNA-positive patients to care. This design can be feasibly replicated by other EDs given limited non-clinical training required for linkage-to-care staff. Adoption of similar programs in other EDs may improve the rates of LTC and treatment initiation for previously diagnosed HCV patients.  相似文献
