Introduction: The aim of this study was to assess the impact of nerve sparing surgery and major abdominal surgery on sexual and urinary function in men and women with colorectal cancer undergoing rectal dissection and segmental colectomy., Method: Forty-eight patients (group A: 22 males, 26 females; median age 55 years) undergoing rectal dissection were compared with 24 having segmental colectomy (group B: 12 male, 12 female; median age 55 years). Preoperative data were also compared with age- and gender-matched controls (group C)., Results: More patients after rectal dissection vs segmental colectomy had urinary tract infections [15 (31%) vs 3 (17.5%), P = 0.04]. At 37 months, urinary dysfunction after rectal excision was seen in 29 (60%; 20 men) vs nine (37.5%; eight men) after segmental colectomy. Postoperative urinary symptoms were significant in group A, but not in group B (pre: vs post; groups A and B: poor stream--13%vs 38%, P = 0.001 and 21%vs 21%, P = NS; incontinence--4.2%vs 17%, P = 0.008 and 8%vs 8%, P = NS; hesitancy--13%vs 35%, P = 0.034 and 17%vs 21%, P = NS). Sexual health was worse after rectal excision compared with segmental colectomy (men--62.5%, women--25%vs 44% of men) respectively. Erectile dysfunction was the chief cause (rectal excision--50%vs segmental colectomy - 33%). After rectal excision, 6% of women had dyspareunia and 19% reported reduced orgasm but none after segmental colectomy. Conclusion More men than women had urinary and sexual impairment after rectal excision than after segmental colectomy. Its aetiology is multifactorial.

Introduction: Patients who have a temporary loop ileostomy have impaired quality of life. Complications associated with a loop ileostomy or ileostomy closure will impair patients' quality of life further and require extended enterostomal therapy. We performed a prospective audit of loop ileostomy to ascertain the nature of the workload that may be created with ileostomy-related complications., Patients and Methods: One hundred and forty patients (67 males, 73 females, median age 50 years, range 5-90 years) who received a temporary loop ileostomy were analysed after completion of proformas on a prospective basis between 1999 and 2006., Results: Operation was performed for rectal cancer 100 (71%), familial adenomatous polyposis 14 (10%), ulcerative colitis 21 (15%) and for trauma or Hirchsprung's disease 5 (3%). Complications of loop ileostomy were: retraction 1 (0.7%), ileostomy flux 11 (8%), stomal prolapse 1 (0.7%), parastomal hernia 1 (0.7%), paraileostomy abscess 4 (3%) and severe skin excoriation 9 (6%). The loop ileostomy was reversed in 117 (83%) at a median (range) of 13 weeks (1-60). Ileostomy closure-related complications were: small bowel fistula 1 (0.9%), small bowel obstruction 5 (4.3%) and a stitch sinus in 1 (0.9%). Five women developed recto-vaginal fistula (n=3; 2.6%), pouch-vaginal fistula (n=1; 0.9%) and pouch-anal fistula (n=1; 0.9%) that required extended enterostomal therapy, after loop ileostomy reversal., Conclusion: Nineteen percent of patients following creation of a loop ileostomy and 10.5% of patients after reversal of the ileostomy required extended enterostomal care by a specialized enterostomal therapist, which supported resumption of a normal life.

Introduction: The prevalence and survival of colorectal cancer in Sri Lankans has not been previously reported. We did a retrospective and a prospective survey, in the region of North Colombo, Sri Lanka between 1992 and 2004. The aim was to study cancer burden, sites of colorectal cancer and survival after surgery., Patients and Methods: The records of 175 patients with colorectal cancer between 1992 and 1997 in the selected region of were analysed retrospectively. A prospective study was performed in 220 new patients with colorectal cancer between 1996 and 2004. Data evaluated were demographics, tumour stage and survival., Results: Between 1992 and 1997 the crude annual incidence of colorectal cancer was 1.9 per 100,000, which increased over the years. The current national crude annual incidence is 3.2 per 100,000 in women and 4.9 in men. Median age at presentation was 60 years with similar prevalence of cancer in men and women. In the entire group, 28% of cancers were in those less than 50 years old. Survival at 2 and 5 years was 69% and 52%. The majority of cancer related deaths were within the first 2 years after surgery., Conclusion: The burden of colorectal cancer in Sri Lanka is on the rise. Up to a third of cancers occur in those under 50 years, and the majority of cancers are in the rectum or rectosigmoid region. Flexible sigmoidoscopy offers a useful screening tool.

Introduction: Fecal incontinence (FI) impairs quality of life. We performed an audit of biofeedback (BFB) in management of patients with FI., Methods: Fifty patients (median [range] age 30 [4-77] years; 28 men) who received BFB for median (range) of 15 weeks (4-28), either postoperatively (n=39), or as the sole treatment (n=11) were evaluated. Cleveland continence score (0-good, 20-poor), anorectal manometry parameters, and patient satisfaction (assessed by Fecal Incontinence Quality of Life Scale [FIQLS]) were evaluated at baseline and after the BFB therapy in all patients., Results: Continence scores improved after intervention. In the surgery + BFB group, mean (SD) continence scores baseline vs. postsurgery + BFB (post-treatment) were 18.2 (3.9) vs. 6 (5.9; p< 0.01). In the BFB alone group, scores were similar at baseline 11.7 (5.9) and 6.1 (5.2) post BFB (p=0.08). Maximum resting anal pressure (MRP) improved from preoperative 12.6 (9.8) mmHg to: vs. 21.1 (11.9) mmHg post-treatment (p< 0.01). In patients who received BFB alone, MRP did not change significantly (pre vs post BFB 22.9 (11.7) mmHg vs. 29.6 (12.1) mmHg [p=0.08]). Maximal squeeze pressure improved significantly (preoperative vs. post-treatment: 46.3 (41.2) mmHg vs. 78.3 (33.9) mmHg [p< 0.01]; pre vs. post BFB alone: 72.4 (34.8) mmHg vs. 114.5 (43.1) mmHg [p< 0.01]). In 29 patients (19 surgery + BFB; 10 BFB alone), maximal tolerable volume in saline continence improved from baseline 47.9 (27.4) mL to 152.6 (87) mL after surgery + BFB (p< 0.01); pre vs. post BFB: 98 mL (95.9) vs. 205 (134.3) p< 0.02]. There was significant improvement in all parameters of FIQLS in both groups: lifestyle (p< 0.02), coping/behavior (p< 0.02), depression/self perception (p< 0.02) and embarrassment (p< 0.02)., Conclusion: BFB therapy with or without surgical reconstruction of the damaged anal sphincter improves maximum squeeze pressure, saline retention capacity, quality of life and is a useful first line treatment for fecal incontinence.

Introduction: Economic constraints remain one of the major limitations on the quality of health care even in industrialised countries. Improvement of quality will require optimising facilities within available resources. Our objective was to determine costs of surgery and to identify areas where cost reduction is possible., Patients and Methods: 80 patients undergoing routine major and intermediate surgery during a period of 6 months were selected at random. All consumables used and procedures carried out were documented. A unit cost was assigned to each of these. Costing was based on 3 main categories: preoperative (investigations, blood product related costs), operative (anaesthetic charges, consumables and theatre charges) and post-operative (investigations, consumables, hospital stay). Theatre charges included two components: fixed (consumables) and variable (dependent on time per operation)., Results: The indirect costs (e.g. administration costs, 'hotel' costs), accounted for 30%, of the total and were lower than similar costs in industrialised nations. The largest contributory factors (median, range) towards total cost were, basic hospital charges (30%; 15 to 63%); theatre charges fixed (23%; 6 to 35%) and variable (14%; 8 to 27%); and anaesthetic charges (15%; 1 to 36%)., Conclusion: Cost reduction in patients undergoing surgery should focus on decreasing hospital stay, operating theatre time and anaesthetic expenditure. Although definite measures can be suggested from the study, further studies on these variables are necessary to optimise cost effectiveness of surgical units.
