1. Mr. X.Y.Z, a 42-year-old male, presented with abdominal pain, vomiting, distension and constipation. Examination found an abdominal mass and investigations confirmed rectal cancer. 2. Exploratory laparotomy revealed a 8cm rectosigmoid mass without metastases. A transverse colostomy and biopsy were performed. 3. The patient later underwent a low anterior resection, total mesorectal excision and double stapling anastomosis. The surgery was successful and the patient was discharged on post-op day 7.

- 20. Exploratory laparotomy….. Findings….. 1. A 8 cm growth at the Recto-sigmoid junction about 10 cm from the anal verge. 2. Fully distended small and large bowel. 3. No Liver mets. 4. No peritoneal seeding. 5. No enlarged intra-abdominal lymph nodes.
- 21. Exploratory laparotomy….. Procedure….. Transverse Colostomy and small & large bowel decompression was done. Biopsy of the recto-sigmoid growth was also taken. As the patient was not vitally stable, so resection of the tumor was not done. Plan….. To stablize the patient for elective procedure after histopathology report.
- 22. Sigmoidoscopy….. Histopathology of the recto-sigmoid growth….. Growth in the rectum totally obstructing the lumen about 12 cm from anal margin. Further colonoscopy not possible. Mucosal biopsy taken and preserved for histopathology. Signet Ring Cell Adenocarcinoma

- 41. literature review Overall, colorectal cancer is the second most common malignancy in western countries, with approximately 18 000 patients dying per annum in the UK.
- 42. Origin & presentation » Colorectal cancer arises from adenomas in a stepwise progression in which increasing dysplasia in the adenoma is due to an accumulation of genetic abnormalities. » Usually, these carcinomas present as an ulcer, but polypoid and infiltrating types are also common.
- 43. Dukes’ staging….. » A: limited to the rectal wall: prognosis excellent. » B: extended to the extrarectal tissues, but no metastasis to the regional lymph nodes: prognosis reasonable. » C: Secondary deposits in the regional lymph nodes. a) C1. Pararectal lymph nodes alone are involved b) C2. Nodes accompanying the supplying blood vessels are implicated up to the point of division. Prognosis is poor. » D: Widespread metastasis… usually hepatic.
- 45. Diagnosis and assessment of rectal cancer….. All patients with suspected CA rectum should undergo: ■ Digital rectal examination ■ Sigmoidoscopy and biopsy ■ Colonoscopy if possible ■ CT colonography or barium enema if colonoscopy not possible.
- 46. Diagnosis and assessment of rectal cancer….. All patients with proven CA rectum require staging by: ■ Imaging of the liver and chest, preferably by CT ■ Local pelvic imaging by magnetic resonance imaging or endoluminal ultrasound.
- 47. Management of rectal cancer….. » Radical excision of the rectum, together with the mesorectum and associated lymph nodes, should be the aim. » Rectosigmoid tumours and those in the upper third of the rectum are removed by ‘high anterior resection’, in which the rectum and mesorectum are taken to a margin 5 cm distal to the tumour, and a colorectal anastomosis is performed.
- 48. Management of rectal cancer….. » Tumours in the middle and lower thirds of the rectum, complete removal of the rectum and mesorectum is required, i.e. total mesorectal excision (TME). A temporary protecting stoma is usually formed after TME.
- 54. ADVANTAGES OF STAPLER ANASTOMOSIS….. LIMITATION….. » Less time consuming. » Minimum risk of leakage. » Low incidence of pelvic sepsis. » Early recovery. » High cost.
