Omission of concurrent chemoradiation after a response to neoadjuvant chemotherapy in locally advanced rectal cancer with a synchronous liver metastasis: a note of caution.

There is clear evidence to support the use of pre-operative concurrent chemo-radiotherapy (CRT) in locally advanced rectal cancer. In the UK, most patients are selected for treatment if the resection margin is predicted to be involved. The selection criteria used includes primary tumours that threaten the resection margins on high-resolution pelvic MRI and low tumours requiring abdominoperineal excision. There is no consensus, however, to guide the treatment of patients who present with advanced rectal disease and synchronous, potentially resectable, metastatic disease. This case illustrates the potential risk of omitting radiation following a good response to neoadjuvant systemic chemotherapy.

Early symptomatic recurrence after intestinal resection in Crohn's disease is unpredictable.

OBJECTIVE: To identify predictors of early symptomatic recurrence of Crohn's disease (CD) after surgical resection. METHOD: We studied a cohort of 128 patients who had undergone at least one intestinal resection for CD. Factors that might predict early recurrence were documented for analysis using a standardized pro forma. These comprised age, gender, family history, extra-intestinal manifestations, smoking, complicated disease at first presentation, site of disease, preoperative inflammatory markers, involvement of resection margins, orientation and method of anastomosis and postoperative medical therapy. All symptomatic recurrences were confirmed by endoscopic, radiological, or operative means. We defined early recurrence as that which occurred within 36 months of first surgery. Univariate analysis was conducted to compare the distribution of each factor in those who developed early recurrence (n = 48) and those who remained disease free for the first 36 months (n = 50). RESULTS: Of the 128 patients studied, 98 fulfilled the inclusion criteria of at least 36 months of follow up. Of these patients, 48 (49%) patients developed recurrence. Trends towards fewer early recurrences were seen in patients with colonic disease (33%vs 56%, P = 0.068). Of the current smokers, 60% developed early recurrence compared with 43% of nonsmokers (P = 0.269). All other factors examined were similarly distributed between the two groups. Metronidazole as adjuvant treatment does not appear to protect against early symptomatic recurrence. CONCLUSION: This study shows that early symptomatic postoperative recurrence of CD remains unpredictable. Against expectation, abstinence from smoking and postoperative adjuvant metronidazole did not appear to protect against early symptomatic recurrence.

Tales from the frontline: the colorectal battle against SARS.

OBJECTIVE: The recent worldwide epidemic of Severe Acute Respiratory Disease (SARS) caused over 800 deaths and had a major impact on the health services in affected communities. The impact of SARS on colorectal surgery, particularly service provision and training, is unknown. This paper reports these changes from a single colorectal unit at the centre of the outbreak. PATIENTS AND METHODS: Hospital databases and electronic patient records covering the 4 months duration of the SARS epidemic and an equivalent period preceding SARS were compared. Data was collected for inpatient admissions, outpatient consultations, operative surgery, colonoscopy and waiting times for appointments or surgery. RESULTS: The SARS epidemic resulted in reductions of 52% for new outpatient attendances, 59% for review attendances, 51% for admissions, 32% for surgical procedures and 48% for colonoscopies. Major emergency procedures, cancer resections and complex major procedures were unaffected. Operative procedures by trainees reduced by 48% and procedures by specialists reduced by 21%. Patients awaiting early or urgent outpatient appointments rose by 200% with waiting times for colonoscopy increased by a median 3, 5 or 9 weeks for outpatient, inpatient or non-urgent cases, respectively. The waiting time for minor elective colorectal surgery was extended by 5 months. CONCLUSION: SARS resulted in a major reduction in the colorectal surgical caseload. The consequences were evidenced by a detrimental effect on waiting times and colorectal training. However, serious pathology requiring emergency or complex surgery was still possible within these constraints.

Administration of peripheral parenteral nutrition: a prospective study comparing rotation of venous access sites with ultrafine cannulas.

Peripheral veins have been used successfully for patients requiring short- to medium-term total parenteral nutrition. This study prospectively compares two methods of peripheral parenteral nutrition (PPN). Forty-six patients requiring parenteral nutrition (PN) were identified prospectively. Fifty courses of PPN were prescribed using a standardized PPN formula of 9.3 g nitrogen, 1400 kCal, 2500 ml (KABI II, Pharmacia). Patients were randomized to receive PPN via 23G, 15 cm flexane catheters (Nutriline) inserted into an antecubital vein which remained in-situ with a continuous infusion over 24 h, or to receive 12-h cyclical infusions through peripherally sited 18G catheters (Venflon) which were removed postinfusion and reinserted into the contralateral forearm on alternate days. Data collected included duration, complications and cost of materials for each prescribed course. A scoring system to determine patient anxiety and depression and a questionnaire regarding patients' perspectives were evaluated. Fifty courses were prescribed, 26 by rotation of veins (RV) and 24 by Nutriline (N). Mean duration of feeding was 7.9 and 8.6 days, respectively; cost of materials were comparable 6.48/day (RV) vs 5.17/day (N); 2 RV patients failed to complete their course (no access [P< 0.05], whilst 9 N patients failed to complete their course (4 severe phlebitis, 2 no venous access, 2 septicaemia, 1 dislodged). Five patients required CPN (RV, N 3) while 4 remaining patients were fed by an alternative PPN method. The overall incidence of anxiety was 20% and of depression 16%, with no significant difference between groups. The majority of patients (87%) found mobility restricted. Twelve-hourly infusions via alternate forearm veins were significantly more successful than continuous infusions via Nutriline, both in terms of completion of the prescribed course and less venous morbidity. This study confirms that rotation of forearm veins allows affordable and successful PN administration to the majority of patients, with low PN-related morbidity.

COAD (clinical outcome assessment documentation) charting: using the quality improvement process to meet the new JCAHO nursing standards.

The shortage of nurses has prompted departments across the nation to examine nursing practices in individual healthcare facilities and to initiate changes where relevant. Saint Thomas Hospital, a 571-bed tertiary-care facility, developed a number of strategies designed to allow nurses to focus on skills consistent with professional practice and to reassign technical and clerical duties to other members of the healthcare team. One of the changes implemented was the clinical outcome assessment documentation (COAD) system, which communicates the plan of care without the use of a separate form, expedites charting times, and eliminates duplication. This system also facilitates the documentation of the patient's progress toward outcome-oriented goals. Evaluation of the COAD system after implementation showed improvement in documentation of the nursing process, staff satisfaction with the system, and compliance with the Joint Commission's 1991 nursing standards.

Hiatus hernia and heartburn.

The symptoms in a group of 80 patients with a pure sliding hiatus hernia were investigated using the pyloric regulation test (Capper, Airth, and Kilby, 1966). It was found that there was a high correlation between the symptoms of heartburn and the reflux of duodenal barium into the stomach.
