The aim of this study was to compare the management and outcome of acute cholecystitis in an acute care surgery (ACS) model to that of the traditional home-call attending surgeon. The ACS model is one in which a consultant led team manage all emergency surgical presentations. The consultant is involved with every decision made including theatre allocation. Records of all patients who underwent an emergency cholecystectomy in the 2 years before and after introduction of an ACS model were reviewed. A total of 202 patients were recruited into this study. The groups were matched for sex, age and insurance status. There was a decrease in the median time to theatre (1 versus 2 days) and total length of stay (4 versus 6 days) in the ACS group. There was no significant difference in the conversion rate between the groups. However, there was a decreased complication rate in the ACS group (8.7 versus 17.2%). There were no differences in the histological findings. Consultant presence in theatre was higher in the ACS group (73.9 versus 56.3%), and they were more often assisting (30.4 versus 4.6%). Results suggest that an ACS model is beneficial to patient care with shorter hospital stay and a decreased complication rate. This may reflects a greater input to patient assessment and management by the on-site consultant. In addition, the ACS model provides greater consultant supervision to the trainee.

Objective: To assess the outcomes of appendicectomy in an acute care surgery (ACS) model compared with a traditional on‐call (Trad) model. Design: Retrospective historical control study comparing appendicectomy outcomes in the Trad period (April 2004 to March 2005) with outcomes in the ACS period (April 2006 to March 2007). Setting: The Prince of Wales Public Hospital, a metropolitan tertiary referral centre in Sydney. Patients: All adult patients undergoing appendicectomy during 1‐year periods before and after the introduction of the ACS model. Intervention: The introduction of an ACS model for managing all emergency general surgical presentations. Main outcome measure: Complication rate. Results: A total of 402 appendicectomies were performed, 176 during the Trad period and 226 during the ACS period. There was no perioperative mortality. The complication rate was lower in the ACS period than the Trad period (9.3% v 17.0%; P = 0.02). After the intervention, there was no significant change in the time from presentation to arrival in theatre or in length of stay, but the proportion of operations performed at night (24:00–08:00) was reduced from 26.1% to 15.0% (P = 0.006). The proportion of negative appendicectomies was reduced from 22.7% to 17.3%, but the change was not statistically significant (P = 0.08). There was no difference in perforation rate before and after the intervention (13.6% v 13.3%; P = 0.86). Conclusion: The ACS model provides a safe surgical environment for patients and is associated with a reduced complication rate. Under the ACS model, there was an increase in the number of patients treated conservatively overnight, but this did not lead to an overall increase in perforation rate or length of stay.

Simple transverse resection is not recommended for the short Meckel's diverticulum. A HDR of 2.0 is recommended as the cut-off when deciding on the most appropriate operation. The external appearance of the Meckel's diverticulum does not predict the presence of HGM and is therefore an unreliable indicator to aid resection decisions when presented with an incidental Meckel's diverticulum.

The operating theatre is a complex place. There are many potential factors which can interfere with surgery and predispose to errors. Optimizing the operating theatre environment can enhance surgeon performance, which can ultimately improve patient outcomes. These factors include the physical environment (such as noise and light), human factors (such as ergonomics), and surgeon-related factors (such as fatigue and stress). As individual factors, they may not affect surgical outcome but in combination, they may exert a significant influence. The evidence for some of these working environment factors are examined individually. Optimizing the operating environment may have a potentially more significant impact on overall surgical outcome than improving individual surgical skill.

Slow-transit constipation is characterized by delay in transit of stool through the colon, caused by either myopathy or neuropathy. The severity of constipation is highly variable, but may be severe enough to result in complete cessation of spontaneous bowel motions. Diagnostic tests to assess colonic transit include radiopaque marker or radioisotope studies, and intraluminal tests (colonic and small bowel manometry). Most patients with functional constipation respond to laxatives, but a small proportion are resistant to this treatment. In some patients biofeedback is helpful although the mechanism by which this works is still uncertain. Other patients are resistant to all conservative modes of therapy and require surgical intervention. Extensive clinical and physiological preoperative assessment of patients with slow colonic transit is essential before considering surgery, including an assessment of small bowel motility and identification of coexistent obstructed defecation. The psychological state of the patient should always be taken into account. When surgery is indicated, subtotal colectomy and ileorectal anastomosis is the operation of choice. Segmental colonic resection has been reported in a few patients, but methods of identifying the affected segment need to be developed further. Less invasive and reversible surgical options include laparoscopic ileostomy, antegrade colonic enema and sacral nerve stimulation.

Background: An acute care surgery (ACS) model was introduced to manage emergency surgical presentations efficiently. The aim of this study was to evaluate the impact of patient handover in an ACS model on the outcomes of adhesive small bowel obstruction (SBO). Methods: A retrospective study was performed on patients who were admitted with adhesive SBO at Prince of Wales Hospital. The cohort consisted of all patients treated by the ACS team from its introduction in September 2005 to February 2011. Patients in the ACS cohort were divided into two groups: those whose care was handed over to another surgeon and those whose care was not. These groups of patients were compared with a random sample of 50 patients in the pre-ACS period. Results: In the ACS period, there was no significant difference in complication rates or length of hospital stay in those who were not handed over and those who were. A significantly higher proportion of operations took place during the day for the group who had been handed over (72.7% versus 36.7%; P = 0.005). There were no significant differences in complication rates or length of hospital stay in the pre-ACS and ACS period. Conclusion: Management under an ACS team does not increase adverse outcomes for adhesive SBO. Patients can be safely handed over within an ACS framework. Other members of the ACS team may help facilitate continuity of care.

Local anaesthesia infusion at the fascial plane provides effective analgesia. This improves patient recovery through earlier return to bowel function and mobilization.

Functional impairment and QOL do not necessarily correlate. The development of a validated specific QOL scale for patients with anal fistulas would be important to compare the results of different treatment options. This scale should include social and psychological factors in addition to the physical outcomes.
