Item Histopathology reporting in colorectal cancer: a proforma improves quality(Wiely-Blackwell, 2009) Siriwardana, P.N.; Pathmeswaran, A.; Hewavisenthi, J.; Deen, K.I.AIM: The histopathology report is vital to determine the need for adjuvant therapy and prognosis in colorectal cancer (CRC). Completeness of those in text format is inadequate. This study evaluated the improvement of quality of histopathology reports following the introduction of a template proforma, based on standards set by the Royal College of Pathologists (RCP), UK. METHOD: Sixty-eight consecutive histopathology reports based on 19 items for rectal cancer (RC) and 15 items for colon cancer (CC) using the proforma were prospectively analysed and compared with results of a previous audit of 82 consecutive histopathology reports in text format. The percentage of reports containing a statement for each data item for both series was compared using the Normal test for difference between two proportions. Completeness of each report was assessed and a percentage score (percentage completeness) was given. Mean percentage completeness was calculated for each format and compared using the two sample t-test. RESULTS: Except for comments on the presence of 'histologically confirmed liver metastases' in CC and RC, 'distance from dentate line' and 'distance to circumferential margin' in RC, all other items were commented in more than 90% of reports, where 71% of the items based on the minimum data set were present in all reports. Compared to prose format, the mean percentage completeness (SD) improved from 74% (8) to 91% (4) (P < 0.0001) and from 81% (5) to 99% (1) (P < 0.0001) for RC and CC respectively in template proforma format. CONCLUSION: A template proforma and surgeon's contribution in relation to operative findings improves the quality of the histopathology report in CRC.Item Prospective clinical and functional audit of emergency and elective haemorrhoidectomy(College of Surgeons of Sri Lanka, 1999) Deen, K.I.; Paris, M.A.S.; Ariyaratne, M.H.J.; Samarasekera, D.N.Background Traditionally, prolapsed thrombosed haemorrhoids have been treated conservatively because of the popular belief that the incidence of complications are greater after emergency operation compared with elective operation for haemorrhoids. An audit comparing emergency operation for prolapsed thrombosed haemorrhoids with elective operation for third and fourth degree haemorrhoids is presented. Patients and methods 104 patients (82 male, median age 47 years, range -18 to 80 years) undergoing emer- gency (65) or elective haemorrhoidectomy (39) were evaluated for complications after operation, hospital stay and postoperative bowel function which was assessed at 3 months by mailed questionnaire. Results Trainees performed as many operations as consultants (trainee 48 (46 percent) vs. consultant 56 (54 percent) although consultants performed more emergency operations (trainee-20, consultant-45). Postoperative complications were seen in 13 (12percent) ; emergency-9 versus elective-4 (p=0.69). There was no difference in complications after trainee performed operation (8) compared with operation by consultant (5). Median (range) duration of hospital stay after emergency operation was 2 days (1-17) compared with elective operation -2 days (1-10). A subset of 41 patients responded to a questionnaire on bowel function at 3 months: 5 of twenty five (20 percent) after emergency haemorrhoidectomy and 2 of sixteen (12.5 percent) after elective haemorrhoidectomy reported transient incontinence to gas or stool up to 3 weeks after operations but none were incontinent at 3 months. After emergency haemorrhoidectomy, 9 (36 percent) reported a sense of anal narrowing compared with 2 (12.5 percent) after elective haemorrhoidectomy (p=0.13). None required corrective surgery for anal stenosis. Conclusion There were no significant differences in complications, hospital stay and postoperative bowel function in patients after emergency and elective haemorrhoidectomy. Emergency haemorrhoidectomy is likely to result in low morbidity when undertaken by trained persons.Item Clinical audit on screening for cardiovascular risk factors(College of General Practitioners of Sri Lanka, 1996) de Silva, N*.Clinical adults is the method used to assess evaluate and improve the care of patients in a systematic way. An adult was carried out on screening for three cardiovascular risk factors, namely asymptomatic hypertension, heper cholesterolemia and diabetes mellitus among patients over the age of forty years, consulting the doctor. Results revealed that the high standard expected with regard to screening for cardiovasccular risk factors had not met in this practice population. Corrective actions have been proposed in order to achieve the standard.
