Sexual and urinary dysfunction following rectal dissection compared with segmental colectomy.

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.

Complications of loop ileostomy and ileostomy closure and their implications for extended enterostomal therapy: a prospective clinical study.

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.

Prevalence of colorectal cancer and survival in patients from the Gampaha District, North Colombo region.

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.
