Effect of the introduction of an emergency general surgery service on outcomes from appendicectomy.

BACKGROUND: Appendicectomy is a common general surgical emergency procedure and may be used as a surrogate marker to evaluate quality in surgical management. The aim of this study was to assess the outcomes of appendicectomy before and after the introduction of a consultant-led emergency general surgery (EGS) service at a large metropolitan tertiary referral centre. METHODS: A retrospective historical control study was performed that included all adult patients undergoing appendicectomy during two 18-month periods, before and after the introduction of the EGS service. Data collected included patient demographics, use of radiological investigations, time to surgery, length of hospital stay and histopathology findings. Outcome measures were time to surgery, hospital length of stay, use of radiological investigations, negative appendicectomy rate and perforation rate. RESULTS: A total of 675 patients were identified of whom 276 had an appendicectomy before the EGS service was introduced (2008-2009) and 399 after its introduction (2011-2012). The EGS service resulted in an increase in time to surgery (15 versus 18 h; P < 0.001) with no increase in length of hospital stay (3 days for both periods; P = 0.424). An increase in the rate of appendicectomies performed within office hours was seen (54.3 versus 64.4 per cent; P < 0.001), with no significant increase in negative appendicectomy (13.0 versus 15.8 per cent; P = 0.322) or perforation (8.3 versus 5.5 per cent; P = 0.149) rates. The use of preoperative computed tomography reduced from 38.4 to 26.6 per cent (P = 0.001). CONCLUSION: The introduction of a consultant-led EGS service resulted in a decrease in the use of computed tomography and a greater proportion of appendicectomies performed within office hours, with no increase in length of stay. Overall negative appendicectomy and perforation rates did not change.

Gender differences in mortality, quality of life and function after restorative procedures for rectal cancer.

AIM: Studies investigating the functional outcome after restorative surgery for rectal cancer have mainly focused on the effect of different surgical techniques on bowel habit or sexual activity at a single time-point. The aim of this study was to assess, longitudinally, the effect of rectal cancer treatment on bowel function, quality of life and sexual activity. METHOD: The study parameters were assessed using self-administered questionnaires, including the Short Form 36 (SF-36), repeatedly, over a 5-year period. Patient details were obtained from the Cleveland Clinic prospective database. RESULTS: There were 260 (186 male) patients. The mean ages of male and female patients at the time of surgery were 60.5 and 57.5 years, respectively. There was no significant difference in comorbidity or stage between the groups. Women had a better overall survival. More women than men had postoperative radiation and perioperative blood transfusions. Men had a higher percentage of hand-sewn anastomoses (23.9%vs 10.8%, P = 0.018), but there was no overall difference in the mean level of anastomosis (2.3 cm vs 1.9 cm, P = 0.38). Men had worse nocturnal bowel function, more incontinence and a poorer mental component score on the SF-36. Pad use increased over time to a greater degree in women. Sexual activity, which was similar in men and women at baseline, had fallen at 5 years in both genders. CONCLUSION: After restorative resection for rectal cancer, bowel function is worse in men than in women, especially night evacuation at 3 and 5 years postoperatively. Sexual function in both genders declines sharply initially within 1 year postoperatively and more gradually over 5 years.

Predictors of clinic non-attendance: opportunities to improve patient outcomes in colorectal cancer.

AIM: Colorectal cancer is one of the few tumour types, where routine patient follow up has been demonstrated to impact significantly on survival. Patients who fail to attend regular clinic reviews may compromise their outcome, but the frequency at which this occurs is unknown. Identifying the extent of this problem, and the factors that predict non-attendance, may provide opportunities to improve patient outcomes. METHODS: Utilizing the Australian Comprehensive Cancer Outcomes and Research Database (ACCORD) colorectal database at Royal Melbourne and Western Hospitals and the Hospital Patient Management System (HOMER) we collected attendance data for colorectal surgical and oncology outpatient clinic appointments. RESULTS: A total of 619 patients (368 men and 251 women) with curatively treated Australian ClinicoPathological Staging System (ACPS) Stage A, B and C colorectal cancer was identified from the two sites over 1988-2008. Twenty-one per cent (n= 130) of patients failed to attend one or more appointments. Patients who failed to attend were more likely to require the services of an interpreter (25% vs 18%; P= 0.007), to have a smoking history and to have not received adjuvant therapy. Tumour site, patient age, sex and comorbidities were not associated with non-attendance. CONCLUSION: A significant percentage of patients fail to attend routine clinic visits to colorectal speciality clinics. Patients at risk of non-attendance can be identified. More research is needed to identify barriers as to why patients do not attend appointments and to develop measures that may improve patient attendance.

Preoperative immunonutrition and its effect on postoperative outcomes in well-nourished and malnourished gastrointestinal surgery patients: a randomised controlled trial.

BACKGROUND/OBJECTIVES: Invasive procedures such as surgery cause immunosuppression, leading to increased risk of complications, infections and extended hospital stay. Emerging research around immune-enhancing nutrition supplements and their ability to reduce postoperative complications and reduce treatment costs is promising. This randomised controlled trial aims to examine the effect of preoperative immunonutrition supplementation on length of hospital stay (LOS), complications and treatment costs in both well-nourished and malnourished gastrointestinal surgery patients. SUBJECTS/METHODS: Ninety-five patients undergoing elective upper and lower gastrointestinal surgery were recruited. The treatment group (n=46) received a commercial immuno-enhancing supplement 5 days preoperatively. The control group (n=49) received no supplements. The primary outcome measure was LOS, and secondary outcome measures included complications and cost. RESULTS: A nonsignificant trend towards a shorter LOS within the treatment group was observed (7.1 ± 4.1 compared with 8.8 ± 6.5 days; P=0.11). For malnourished patients, this trend was greater with hospital stay reduced by 4 days (8.3 ± 3.5 vs 12.3 ± 9.5 days; P=0.21). Complications and unplanned intensive care admission rates were very low in both the groups. The average admission cost was reduced by AUD1576 in the treatment group compared with the control group (P=0.37). CONCLUSIONS: Preoperative immunonutrition therapy in gastrointestinal surgery has the potential to reduce the LOS and cost, with greater treatment benefit seen in malnourished patients; however, there is a need for additional research with greater patient numbers.
