Rural general surgeon confidence with managing vascular emergencies: A national survey.

OBJECTIVE(S): Life and limb threatening vascular emergencies often present to rural hospitals where only general surgery services are available. It is known that Australian rural general surgical centres encounter 10-20 emergency vascular surgery procedures annually. This study aimed to assess rural general surgeons' confidence managing emergent vascular procedures. SETTING, PARTICIPANTS AND DESIGN: A survey was distributed to Australian rural general surgeons to determine their confidence (Yes/No) in performing emergent vascular procedures including limb revascularisation, revising arterio-venous (AV) fistulas, open repair of ruptured abdominal aortic aneurysm (AAA), superior mesenteric artery (SMA)/coeliac embolectomy, limb embolectomy, vascular access catheter insertion and limb amputation (digit, forefoot, below knee and above knee). Confidence level was compared with surgeon demographics and training. Variables were compared using univariate logistic regression. RESULTS: Sixteen per cent (67/410) of all Australian rural general surgeons responded to the survey. Increased age, years since fellowship and training prior to 1995 (when separation of Australian vascular and general surgery occurred) were associated with greater confidence in limb revascularisation, revising AV fistulas, open repair of ruptured AAA, SMA/coeliac embolectomy, and limb embolectomy (p < 0.05). Surgeons who completed >6 months of vascular surgery training were more comfortable with SMA/coeliac embolectomy (49% vs. 17%, p = 0.01) and limb embolectomy (59% vs. 28%, p = 0.02). Confidence in performing limb amputation was similar across surgeon demographics and training (p > 0.05). CONCLUSION: Recently graduated rural general surgeons do not feel confident in managing vascular emergencies. Additional vascular surgery training should be considered as part of general surgical training and rural general surgical fellowships.

Diffuse large B cell lymphoma presenting as a peri-anal abscess.

A non-healing peri-anal abscess can be difficult to manage and is often attributed to chronic disease. This case documents a male in his seventh decade who presented with multiple peri-anal collections. The abscess cavity had caused necrosis of the internal sphincter muscles resulting in faecal incontinence. Biopsies were conclusive for diffuse large B-cell lymphoma. A de-functioning colostomy was performed and the patient was initiated on CHOP-R chemotherapy. Anal lymphoma masquerading as a peri-anal abscess is rare. A high degree of suspicion must be maintained for an anal abscess which does not resolve with conservative management.

Primary coronary artery bypass surgery in the presence of decreasing preoperative renal function: effect on short-term outcomes.

BACKGROUND: This study evaluated the impact of decreasing renal function on short-term outcomes in patients undergoing primary coronary artery bypass grafting (CABG). METHODS: The study period was from February 1999 to February 2009. Data on 4050 patients undergoing primary CABG were prospectively collected and analyzed retrospectively. The study population was divided into 3 groups: the CABG:N group, patients with preoperative serum creatinine levels <2 mg/dL (n = 3947); the CABG:RF group, patients with preoperative creatinine levels >2 mg/dL (n = 87); and the CABG:D group, patients on dialysis (n = 16). RESULTS: The significant differences between the groups (CABG:D > CABG:RF > CABG:N) in short-term outcomes were with respect to blood product use (P < .001), postoperative acute myocardial infarction (P < .001), pulmonary complications (P .001), infection (P < .001), and death (P < .001). The risk of short-term death (30 days) in the CABG:D group (4/16, 25%) was 25 times greater than that in the CABG:N group (38/3947, 0.96%). CONCLUSION: CABG in the presence of renal failure is associated with significant morbidity and mortality.

Cardiac surgery in the presence of dialysis: effect on mid-term outcomes and quality of life.

BACKGROUND: this study evaluates the impact on short and mid-term outcomes and quality of life of dialysis dependent patients undergoing cardiac surgery. The benefit to patients from a bio-psycho-social perspective is put into context via an inter-personal patient interview. METHODS: the study period was from February 1999 to February 2009. Data on 45 dialysis dependent patients undergoing cardiac surgery was prospectively collected and analysed retrospectively. The mean age was 59.9 years and sex ratio (M:F) of 32:13. All patients were New York Heart Association (NYHA) class >2 preoperatively. Fifty-five percent (25/45) of these patients had coronary artery bypass graft surgery (CABG) and 28% (12/45) aortic valve replacement surgery alone. Forty-two variables were studied to define predictors of outcome. Follow-up was 100% (18/18) with a mean follow-up time of 48.1 months (0-124 months). They were followed up with quality of life and functional coping score surveys (SF-36). RESULTS: the main postoperative morbidities were pulmonary complications 20% (9/45), multi-organ failure 11% (5/45) and blood transfusion rates 40% (18/45). The 30 day mortality of the dialysis patients was 13.3% (6/45) and late death was 54% (21/39). Increasing age, pulmonary complications and blood product usage were the significant predictors of both 30 day mortality (age: p=0.02, pulmonary: p=0.003, blood product usage: p=0.03) and late death (age: p=0.008, pulmonary: p=0.02, blood product usage: p=0.02). New York Heart Association class was I-II in 83% (15/18) on long term follow up. All five patients awaiting renal transplants received their transplant in the first six months post-operatively. The overall survival at one year was 78% and five years was 40%. On SF-36 health questionnaire all patients scored less on physical functioning than the Australian norms (24.89 ± 4.10). CONCLUSIONS: cardiac surgery in the presence of renal failure is associated with significant morbidity and mortality. The overall survival and quality of life of dialysis patients undergoing cardiac surgery is poor.
