The first 1000 patients on an internet-based colorectal neoplasia database across private and public medicine in Australia: development of a binational model for the Colorectal Surgical Society of Australia and New Zealand.

BACKGROUND: Collection of multi-institutional data pertaining to the treatment of bowel cancer has been hindered by poor clinician compliance with data entry and the lack of incentive to participate. OBJECTIVE: This study aimed to establish if a novel browser-based model of data collection results in complete data capture. DESIGN: A Web-based data collection interface was custom written, offering automated reporting modules for clinical outcome to participants and an automated reporting system for outstanding data fields, and summary reporting of surgical quality outcomes. The software was combined with a clinical feedback system incorporating fortnightly data review meetings, at the time of clinical multidisciplinary meetings. PATIENTS AND SETTING: Selected were 932 consecutive patients with opt-out consent from 3 hospital sites, including public and private medicine. MAIN OUTCOME MEASURES: The primary outcomes measured were the analysis of data completeness and accuracy and ensuring that the highest-quality data were used for clinical audit of the surgical practices of Australian colorectal surgeons for the purpose of quality assurance. RESULTS: A total of 932 men and women, 22 to 94 years of age, treated for colorectal neoplasia were evaluated. We obtained 100% completion (>27,000 data points) of perioperative data registered by 8 specialist colorectal surgeons and a full-time database manager. CONCLUSIONS: Data completeness and validity are essential for clinical databases to serve the purpose of quality assurance, benchmarking, and research. The results confirm the safety and efficacy of colorectal cancer surgery in both the public and private sector in Australia. The combination of a simple multiuser interface, defined data points, automated result-reporting modules, and data-deficiency reminder module resulted in 100% data compliance in nearly 1000 clinical episodes. The unprecedented success of this model has lead to the Colorectal Surgical Society of Australia and New Zealand adopting this model for data collection for Australia and New Zealand as the binational database.

Governing the surgical count through communication interactions: implications for patient safety.

BACKGROUND: Intermittently, the incidence of retained surgical items after surgery is reported in the healthcare literature, usually in the form of case studies. It is commonly recognised that poor communication practices influence surgical outcomes. AIM: To explore the power relationships in the communication between nurses and surgeons that affect the conduct of the surgical count. METHODS: A qualitative, ethnographic study was undertaken. Data were collected in three operating room departments in metropolitan Melbourne, Australia. 11 operating room nurses who worked as anaesthetic, instrument and circulating nurses were individually observed during their interactions with surgeons, anaesthetists, other nurses and patients. Data were generated through 230 h of participant observation, 11 individual and 4 group interviews, and the keeping of a diary by the first author. A deconstructive analysis was undertaken. RESULTS: Results are discussed in terms of the discursive practices in which clinicians engaged to govern and control the surgical count. The three major issues presented in this paper are judging, coping with normalisation and establishing priorities. CONCLUSIONS: The findings highlight the power relationships between members of the surgical team and the complexity of striking a balance between organisational policy and professional judgement. Increasing professional accountability may help to deal with the issues of normalisation, whereas greater attention needs to be paid to issues of time management. More sophisticated technological solutions need to be considered to support manual counting techniques.

Factors influencing uptake of genetic testing for colorectal cancer risk in an Australian Jewish population.

There is a significant excess of colorectal cancer in the Australian Ashkenazi Jewish community. This excess can partially be attributed to inherited factors that are over represented in this population, such as the APC variant I1307K, which is associated with a modest increase in colorectal cancer risk. There is currently only sporadic clinical genetic testing offered for this variant, as neither the exact increase in cancer risk and therefore the appropriate screening strategies for I1307K carriers, nor the acceptability of such testing in Jewish communities have been determined. This study reports a high acceptability of such genetic testing within a community sample of 300 Australian Jewish individuals--94% of participants would have a test for predisposition to colorectal cancer and a majority would make this decision based on the desire for information for their families and to decrease their own cancer risk. Some concerns were noted about genetic testing for cancer predisposition, including insurance discrimination, test accuracy and confidentiality.

Prescreening evaluation of a brush-based faecal immunochemical test for haemoglobin.

OBJECTIVES: To undertake a prescreening evaluation of a new brush-based faecal immunochemical test for haemoglobin, relative to a traditional spatula-sampling immunochemical test. SETTING: Patients aged between 24 and 90 years, scheduled to undergo diagnostic colonoscopy in two major urban hospitals, for a range of clinical indications. DESIGN: Patients sampled three stools using a spatula for the reference FlexSure OBT test and two stools using a brush for the InSure test; order of sampling was randomised. Faecal haemoglobin was quantified by a modified InSure in a subset of patients to determine whether brush-sampling allowed discrimination between groups. MAIN OUTCOME MEASURES: Sensitivity for cancer or adenoma; false-positive rate in normals. Faecal haemoglobin levels. Preference for sampling method. RESULTS: InSure and FlexSure OBT did not differ in their sensitivities for cancer (27/36, 75% vs 29/36, 80.5%, respectively), adenomas >or= 10 mm (12/29, 41.4% vs 13/29, 44.8%) or adenomas <10 mm (each 8/56, 14.3%). Likewise, false-positive rates in normals were similar: 4/179 (2.2%) and 5/179 (2.8%) respectively (specificities of 97.8% and 97.2%, respectively). Levels of faecal haemoglobin were highest in those with cancers; those with adenomas had intermediate levels which were also significantly higher than those in normals. The brush sampling method was preferred by 38/46 (82.6%), while 4/46 (8.7%) preferred the spatula (p<0.00001). CONCLUSIONS: InSure is as sensitive and specific as FlexSure OBT for faecal haemoglobin. The novel stool-sampling method of InSure allows discrimination between normals and classes of neoplasia, and is highly preferred. The brush-sampling faecal immunochemical test InSure should now be evaluated in a screening population.

Local recurrence after curative anterior resection with principally blunt dissection for carcinoma of the rectum and rectosigmoid.

PURPOSE: The aim of this study was to determine the incidence of local pelvic recurrence of carcinoma of the rectum and rectosigmoid (tumors where the lower edge is 18 cm or less from the anal verge) in a consecutive series of patients operated on by a single surgeon. All patients underwent curative anterior resection and a formal anatomic dissection of the rectum where mobilization was achieved through a principally careful blunt manual technique along fascial planes, preserving an oncologic package. METHOD: During the period April 1986 to December 1997, 157 consecutive anterior resections for carcinoma of the rectum and rectosigmoid were performed by one surgeon (ALP). One hundred thirty-eight (87.9 percent) were curative, and 19 (12.1 percent) were palliative. The mean follow-up period was 46 +/- 31.6 (range, 2-140) months. Data were retrospectively collated and computer coded by an independent contracted medical research team. Follow-up data were available on all patients. RESULTS: Four (3.1 percent) of the 131 patients undergoing curative anterior resection had local recurrence. Local recurrences occurred between 16 and 38 months from the time of resection, and the cumulative risk of developing local recurrence at five years was 5.2 percent. All tumors in which pelvic recurrence occurred were high grade, and the probability of developing local recurrence at five years for this group was 13.9 percent, which is significantly higher compared with patients who had average or low-grade tumors (P = 0.01). The probability of developing local recurrence at five years for Stage I tumors was 0, Stage II was 5.9 percent, and Stage III was 8.9 percent. In addition, there was a significantly higher incidence of local recurrence in the group of patients undergoing ultralow anterior resection (between 3 and 6 cm from the anal verge) as compared with patients undergoing low or high anterior resection (P = 0.03). Local recurrence developed in 3 of 28 (10.7 percent) patients having ultralow anterior resection, 1 of 57 (1.8 percent) patients having low anterior resection (between 6 and 10 cm from the anal verge), and no patients having high anterior resection (above 10 cm from the anal verge). The clinical anastomotic leak rate for curative anterior resection was 7 of 131 patients (5.3 percent). Thirty-seven of the 131 (28.2 percent) required a proximal defunctioning stoma; 35 (41.2 percent) of these were established for low or ultralow anterior resections and 2 for high anterior resection. The overall five-year cancer-specific survival rate of the entire group of 131 patients was 81.8 percent, and the overall probability of being disease free at five years including both local and distal recurrence was 72.9 percent. Three local recurrences occurred in the 101 patients (77 percent) who did not receive any form of adjuvant therapy. One local recurrence occurred in the 18 patients (13.7 percent) who had adjuvant chemoradiation. No recurrence occurred in the 12 patients (9.2 percent) who had adjuvant chemotherapy alone. CONCLUSION: Curative anterior resection for carcinoma of the rectum and rectosigmoid with principally blunt dissection of the rectum in this study is associated with a 3.1 percent incidence and a 5.2 percent probability at five years of developing local recurrence. Evidence from this study indicates that, as with sharp pelvic dissection, a low incidence and probability of local recurrence can be achieved by a principally blunt mobilization technique through careful attention to preservation of fascial planes in the pelvis and removal of an oncologic package with selective rather than routine adjuvant or neoadjuvant chemoradiation.

Treatment of anal fissure with glyceryl trinitrate in patients referred for surgical management.

BACKGROUND: A number of recent studies indicate that anal fissure may be treated by applying glyceryl trinitrate (GTN) ointment. The present study aims to determine the effectiveness and patient acceptability of GTN treatment for patients referred to a consultant surgeon. METHODS: A prospective study of 65 consecutive patients referred to one surgeon (ALP) over a 12-month period was undertaken. All patients were offered 0.2% GTN ointment to be applied intra-anally four times daily for 4 weeks. Informed consent was obtained and review planned for 4 weeks. RESULTS: Fourteen patients declined treatment and nine of the 14 (64%) subsequently underwent lateral sphincterotomy. Twelve of the 51 patients (18.5%) who accepted treatment could not complete it due to headache or persisting severe anal pain. Thirty-nine of the 51 patients (77%) were able to complete 4 weeks of treatment. Twenty-two of the 39 reported an improvement in symptoms. A total of 22 patients (43%) who started GTN treatment subsequently underwent lateral sphincterotomy. CONCLUSIONS: Evidence from the present study suggests that GTN ointment has a place in the management of referred patients with severe and/or chronic anal fissure, but sphincterotomy remains an important treatment option for the majority.

Haemorrhoids: a clinical update.

Haemorrhoids are common, but careful clinical assessment is necessary to ensure that more significant bowel disease is not overlooked. Most patients with haemorrhoids can be managed non-surgically in an office setting, but conventional haemorrhoidectomy is the best option for patients with large symptomatic haemorrhoids.

Psychiatric disturbance and acute stress responses in surgical patients.

BACKGROUND: A number of reports have appeared of post-traumatic stress symptoms occurring in physically ill patients. This study sought to measure the extent of psychiatric disturbance and acute post-traumatic stress reactions occurring in surgical inpatients, and to examine their relationship with the stress of illness and hospitalization and the personal coping style of the patient. METHODS: Thirty-seven admissions to a general surgical unit were assessed on admission and immediately prior to discharge. Measures were made of depression, anxiety, cognitive impairment, post-traumatic stress symptoms, severity of illness, level of physical functioning, degree of hospital stress and coping style. RESULTS: There was a significant reduction in anxiety scores postoperatively. Twenty-seven per cent of patients developed high levels of acute post-traumatic stress symptoms and these correlated with depression at admission and intra-hospital stress. Depression at discharge was related to depression at admission, physical functioning and coping style. In general, avoidance and acceptance-resignation were associated with a poorer psychiatric outcome. CONCLUSIONS: Postoperative psychiatric disturbance, including acute stress symptoms, can be understood as a reaction to the 'trauma' of illness and hospitalization, predisposed to by pre-existing depression. Interventions could be directed at screening for at-risk patients, minimizing stress, and encouraging adaptive mechanisms of coping in patients.

The longer term results of internal anal sphincterotomy for anal fissure.

This study details the results of a retrospective analysis of 98 patients who underwent lateral subcutaneous internal sphincterotomy for the treatment of fissure in ano. Data with particular emphasis on patient satisfaction and anorectal control were collected by postal questionnaire. Minimum follow up was 15 months with an average of 41 months. Ninety-seven per cent of patients indicated that they were moderately or very satisfied with the outcome of the procedure and 90% claimed symptomatic improvement with this being sustained in 69%. Eighteen per cent of patients noted ongoing new problems with minor impairment of anorectal control. Despite these symptoms, 90% of this group were also moderately or very pleased with the outcome and 72% had resolution of their symptoms which was sustained in more than two-thirds of cases. It is concluded that lateral subcutaneous internal sphincterotomy is well tolerated and the majority of patients are more than moderately pleased with the outcome. There was however a significant incidence of minor impairment in anorectal control but this did not detract from the perceived success of the procedure.

Early incisional hernia after use of the 12 mm port for laparoscopic surgery.

This paper reports the complication of early incisional hernia occurring in three patients at the site of entry of a 12 mm disposable port during laparoscopic surgery. To avoid this complication, it is recommended that a 12 mm port be introduced through muscle rather than fascia and, following its removal, the defect in the abdominal wall be closed by sutures.

Laparoscopic assisted right hemicolectomy with Valtrac BAR (Biofragmentable Anastomotic Ring) ileotransverse anastomosis.

Laparoscopic techniques have been employed in a group of medically compromised patients requiring right hemicolectomy, permitting a shorter and lower placed abdominal incision than may have been expected with a conventional surgical approach. In eight patients requiring right hemicolectomy, full mobilization of the right colon from the caecum to the proximal transverse colon was performed laparoscopically. Resection and anastomosis then proceeded through a small right-sided transverse abdominal incision. End to end ileotransverse anastomosis was performed in each instance employing the Valtrac BAR (Biofragmentable Anastomotic Ring) compressive anastomotic technique. The average operating time was 133 min. There was no mortality, but one patient developed pulmonary complications and three developed minor wound infections. An additional three patients developed urinary tract infections. There were no anastomotic complications. The average postoperative stay was 10 days. This study has indicated that laparoscopic techniques can be successfully applied to large bowel surgery, and may be of benefit to high risk patients.
