Has the 'Fast-Track' referral system affected the route of presentation and/or clinical outcomes in patients with colorectal cancer?

BACKGROUND: The aim of this study is to determine whether the 'Fast-Track' referral system has changed the route by which patients present with colorectal cancer (CRC) and whether the route of presentation has any effect on clinical outcome. METHODS: A retrospective cohort study of patients diagnosed with CRC under the care of two consultant colorectal surgeons between April 2006 and December 2012. The route by which patients presented was categorised as Fast-Track (FT), non-Fast-Track (non-FT) or acute. Outcome variables were operative intent, disease stage and 2- and 5-year survival. RESULTS: A total of 558 patients were identified. One hundred ninety-seven patients (35.3 %) were referred as FT, 108 (19.4 %) presented acutely and 253 patients (45.3 %) presented via other routes (non-FT). Over the study period, the route of presentation did not change significantly (P = 0.135). There was no significant difference between FT and non-FT groups in terms of the proportion of patients undergoing potentially curative surgery (70.6 vs 74.3 %, P = 0.092) or with node-negative disease (48.2 vs 52.2 %, P = 0.796) nor was there any difference in 2-year or 5-year survival (74.1 vs 73.9 %, P = 0.837 and 52.3 vs 53.8 %, P = 0.889, respectively). Patients who presented acutely were less likely to undergo curative resection, had more advanced disease and had worse 2- and 5-year survival. CONCLUSIONS: The Fast-Track referral system has not affected the route by which patients present with CRC nor has it had any effect on clinical outcomes. Alternative strategies are required if the desired improvement in outcomes is to be achieved.

The test-retest reliability of fecal incontinence severity and quality-of-life assessment tools.

BACKGROUND: The St. Mark's score and Cleveland Clinic score are widely used for assessing the severity of fecal incontinence, whereas the Rockwood quality of life scale is used to evaluate the impact on the quality of life of patients. OBJECTIVE: The aim of this study was to determine the intra- and interobserver reliability of these assessment tools. DESIGN: All patients were recruited prospectively. To assess intraobserver reliability each patient was asked to complete 4 assessments (the St. Mark's and Cleveland Clinic scores, the Rockwood scale, and a visual analog scale) at 2 time points: initially at recruitment (P1) and then 6 weeks later (P2). No alteration to medications or treatment occurred during this interval. For interobserver reliability, the St. Mark's and Cleveland Clinic scores were also completed by a physician (time point P1) and a nurse (time point P2). OUTCOME MEASURES: Intra- and interobserver reliability were determined by using an intraclass correlation coefficient. An intraclass correlation coefficient value of less than 0.40 indicates poor reliability, values in the range 0.40 to 0.75 indicate fair to good reliability, and a value of greater than 0.75 shows excellent reliability. RESULTS: Thirty-nine patients (34 female) with a median age of 65 years were studied. The intraclass correlation coefficient for intraobserver reliability for the Cleveland Clinic score at time points P1 and P2 was 0.858 (95% CI, 0.611-0.940); and for St. Mark's score, the intraclass correlation coefficient was 0.823 (95% CI, 0.556-0.922). The intraclass correlation coefficients for the quality-of-life domains ranged between 0.864 and 0.938, whereas the intraclass correlation coefficient for the visual analog scale was 0.958 (95% CI, 0.906-0.982). The interobserver reliability ranged from 0.795 to 0.945 for the Cleveland Clinic score and from 0.793 to 0.939 for the St. Mark's score. LIMITATIONS: Of the 39 patients recruited, only 31 patients completed the second assessment at time point P2. This increases the risk of nonresponse error in this study, which is a recognized limitation of mail-mode surveys. CONCLUSION: Current assessment tools for the severity of fecal incontinence and its impact on quality of life have an excellent intra- and interobserver reliability and remain a good objective measure of patients' symptoms (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A135).

Needlestick injuries during surgical procedures: a multidisciplinary online study.

BACKGROUND: Needlestick injuries are common during surgical procedures. Following such an injury, local protocols should be followed to minimize the risk of infection. AIMS: To identify who sustains such injuries, under what circumstances and what actions are taken to minimize the risk and in response to intraoperative needlestick injuries. METHODS: A questionnaire was submitted via e-mail to all staff in a National Health Service trust who took part in operations. The results were checked against occupational health department (OHD) records. RESULTS: One hundred and thirty-six of 255 appropriate responders completed the questionnaire (53%). Fifteen of 31 consultants (48%), 12/36 junior doctors (33%), 0/39 midwives (0%) and 8/30 theatre staff (27%) reported having had at least one intraoperative needlestick injury over the past year. Awareness of local protocols was significantly worse in the junior doctor group. Ninety-three percent of consultants, 67% of junior doctors and 13% of theatre staff did not comply with local protocols. The length of time it takes to do so (48%) and a perceived low infection risk of the patient (78%) were the commonest reasons for this. Hand dominance, role during surgery and double gloving were not significant risk factors; however, rare use of a no-touch technique was. Comparison with OHD records suggested that a maximum of 16% of intraoperative needlestick injuries were dealt with in accordance to local policy. CONCLUSIONS: Non-compliance with needlestick injury protocols is commonest among senior surgical staff. A revision of the protocol to reduce the time it takes to complete it may improve compliance.

Role of clinical pathway in improving the quality of care for patients with faecal incontinence: A randomised trial.

AIM: To assess the development and implementation of the Integrated Rapid Assessment and Treatment (IRAT) pathway for the management of patients with fecal incontinence and measure its impact on patients' care. METHODS: Patients referred to the colorectal unit in our hospital for the management of faecal incontinence were randomised to either the Standard Care pathway or the newly developed IRAT pathway in this feasibility study. The IRAT pathway is designed to provide a seamless multidisciplinary care to patients with faecal incontinence in a timely fashion. On the other hand, patients in the Standard Pathway were managed in the general colorectal clinic. Percentage improvements in St. Marks Incontinence Score, Cleveland Clinic Incontinence Score and Rockwood Faecal Incontinence Quality of Life Scale after completion of treatment in both groups were the primary outcome measures. Secondary endpoints were the time required to complete the management and patients' satisfaction score. χ2, Mann-Whitney-U and Kendall tau-c correlation coefficient tests were used for comparison of outcomes of the two study groups. A P value of 0.05 or less was considered significant. RESULTS: Thirty-nine patients, 34 females, consented to participate. Thirty-one (79.5%) patients completed the final assessment and were included in the outcome analysis. There was no significant difference in the quality of life scales and incontinence scores. Patients in the IRAT pathway were more satisfied with the time required to complete management (P = 0.033) and had stronger agreement that all aspects of their problem were covered (P = 0.006). CONCLUSION: Despite of the lack of significant difference in outcome measures, the new pathway has positively influenced patient's mindset, which was reflected in a higher satisfaction score.

Prevalence of clostridium difficile in excluded colons.

Clostridium difficile infection is associated with substantial morbidity and mortality, increased duration of hospitalization, and a marked economic impact. Several case reports and case series have described C. difficile infection in excluded bowels or immediately after reversal of defunctioning ileostomy. The aim of this prospective study is to detect whether the excluded colon is associated with a higher rate of C. difficile colonization than the normal population, which may increase the risk of C. difficile infection. Patients with defunctioning loop ileostomy, undergoing closure of ileostomy to restore bowel continuity, were prospectively recruited. Two stool samples were collected from the ileostomy effluent before closure of ileostomy and two after the procedure including the first bowel movement. All samples were cultured for C. difficile and analyzed for toxins A and B by a Premier EIA test. Demographic data and possible confounding factors were observed and recorded. Twenty-fine adult patients were recruited to this study; five patients were subsequently excluded. Two patients had positive stool cultures for C. difficile in the postoperative samples and another patient developed clinical pseudomembranous colitis with positive toxin. This indicates a possible colonization rate of 3 to 38 per cent (95% confidence interval). Four observed cases out of the 20 subjects taking part in this study would confidently conclude that C. difficile colonization in the excluded colon is 6 to 44 per cent, i.e., higher than the incidence in the healthy adult population, which is 3 per cent. However, the findings of this study prompt larger and well-powered studies to confirm these findings.

The use of Permacol® injections for the treatment of faecal incontinence.

The aim of this study is to assess the safety and efficacy of Permacol(®) implant for the treatment of idiopathic faecal incontinence using a novel injection technique. Patients with idiopathic passive faecal incontinence were selected for trans-submucosal injection of Permacol(®) after assessment by anorectal physiology and endoanal ultrasonography. Clinical assessment and St. Mark's Incontinence Score were used to evaluate efficacy before and at two time points (1 and 2 years) after treatment. Rockwood Score were also used to determine quality of life before and after treatment. The Friedman and Chi-square tests were used to compare continuous and categorical data, respectively. A p value of <0.05 was deemed significant. Thirty-eight patients (24 female), median age 66 years, were recruited. At maximum clinical follow-up (median of 9 months), response to Permacol(®) injections was categorised as excellent, good, fair and poor in 12, 5, 4 and 17 patients, respectively. St. Mark's Score improved in 72 and 63 % of patients at 1 and 2 years, respectively. However, a smaller proportion of patients (39 and 27 %, respectively) achieved a 50 %, or more, improvement in Mark's Score. All four domains of Rockwood Quality of Life Score improved on first and second year follow-up, however, only two domains, coping and embarrassment, were statistically significant. Permacol(®) injection improved symptoms by >50 % in 39 and 27 % of patients on short and medium-term follow-ups, respectively. The trans-submucosal technique for injection of Permacol(®) in this study was safe with no significant adverse outcomes.

Radical subtotal pancreatic resection, including splenectomy, is an effective one-off treatment for infected pancreatic necrosis.

BACKGROUND: Pancreatic resection for severe acute necrotizing pancreatitis has been associated with prohibitive mortality rates and has been hence replaced by piecemeal debridement, either by the open or the laparoscopic technique. We report the results of deliberate subtotal pancreatectomy with splenectomy for infected pancreatic necrosis. MATERIALS AND METHODS: Six-year prospective audit of patients treated by a single surgeon, with an interest in pancreatic disease, within a Low Volume Hospital (LVH) setting. Results are presented as median (IQR). RESULTS: During the study period 18 patients (9 males) with complicated severe acute pancreatitis underwent radical pancreatic resection. The median age was 61 years (range 36-69). The median time to operation after presentation was 27 days (range 2-74). Microbiological culture confirmed infection in 14 (78%) patients. Three patients (17%) died within 30 days of operation. Twelve of the 15 survivors (80%) underwent a single operative procedure. Three patients required a further laparotomy, of whom 2 required colectomy for ischemia. Median hospital and ICU stays were 43 (range 30-57) and 5 (range 4-6) days respectively. Six patients (40% of survivors) developed an infection of the left half of the chevron incision; however, all wounds were fully healed within 3 months. Long-term follow-up of survivors (n=14) revealed 8 (57%) to need at least occasional pancreatic enzyme supplementation and 5 (36%) to have diabetes mellitus. Two patients (14%) developed an incisional hernia. CONCLUSIONS: Radical resection of pancreas and spleen, combined with postoperative irrigation, was associated with comparatively low rates of morbidity and mortality for patients with infected pancreatic necrosis in a LVH setting.

Role of resting pressure gradient in the investigation of idiopathic fecal incontinence.

PURPOSE: One-third of patients who suffer from idiopathic fecal incontinence are found to have maximum mean resting pressures within the normal range. The objective of this study was to determine whether measuring the gradient of pressure at rest throughout the anal canal is a more sensitive predictor of incontinence in these patients. METHODS: Anorectal physiology measurements were retrospectively reviewed in patients referred over an 18-month period. Two patient groups were selected for the study: Group 1, continent patients (n = 80); and Group 2, patients with idiopathic fecal incontinence (n = 47). Maximum resting pressures, vector volumes, and resting pressure gradients were all contrasted, sensitivities and specificities were calculated, and receiver operating characteristic curve analyses were performed. Reproducibility studies were also performed for the calculation of the pressure gradient. RESULTS: Patient demographics were similar in the two groups. The resting pressure gradient, maximum mean resting pressure, and vector volumes were significantly lower in incontinent patients compared with the normal patients (P < 0.0001, all comparisons). The sensitivity (and specificity) of resting pressure gradient, maximum mean resting pressure, and vector volumes were 89 percent (96 percent), 55 percent (98 percent), and 53 percent (88 percent), respectively. CONCLUSION: The resting pressure gradient is the most accurate in detecting fecal incontinence. The authors conclude that this test is simple, reproducible, and identifies an abnormality in the majority of patients with idiopathic fecal incontinence.

A randomized, double-blind trial of the effect of metronidazole on pain after closed hemorrhoidectomy.

PURPOSE: Patients consider hemorrhoidectomy to be a painful operation. Attempts to reduce the length of inpatient stay have concentrated mainly on a reduction in postoperative pain. Metronidazole has been shown to reduce pain after open hemorrhoidectomy. The aim of this study was to evaluate the effect of metronidazole after closed hemorrhoidectomy. METHODS: Thirty-eight patients undergoing closed hemorrhoidectomy were randomly allocated to receive metronidazole 400 mg (n = 18) or placebo (n = 20) three times daily for seven postoperative days. All patients received a stool softener and analgesics perioperatively. Linear analog scales were used to assess expected pain, actual pain and patient satisfaction. Time to first bowel movement, return to normal activity, complications, and use of additional analgesics were recorded. RESULTS: Both groups of patients experienced less pain than expected. Patients in the metronidazole group required fewer additional analgesics postoperatively (6.3 vs. 26.3 percent), and satisfaction scores in the placebo group were higher at one week (0.5 vs. 2.5), although these differences were not statistically significant. There were no differences in pain actually experienced, time to first bowel movement, return to normal activity, or complications between the two groups. Satisfaction scores at six weeks for all patients were relatively high, with no significant difference between the groups. CONCLUSION: Closed hemorrhoidectomy results in high patient satisfaction and low pain scores. The use of postoperative metronidazole did not reduce postoperative pain.
