- A 56-year-old man presents to the office with biopsy-proven midrectal adenocarcinoma on colonoscopy. Rigid sigmoidoscopy in the office shows a 5-cm circumferential mass 8 cm from the anal verge. Staging evaluation with computed tomography of the chest, abdomen, and pelvis and magnetic resonance imaging of the pelvis preoperatively demonstrates a T3N1M0 cancer. What is the next step in management for this patient?
- A 72-year-old patient with severe systolic congestive heart failure and oxygen-dependent chronic obstructive pulmonary disease completes chemoradiation for a locally advanced rectal adenocarcinoma 5-cm proximal to the anal verge. Reexamination of the rectum 8 weeks after chemoradiation reveals normal, intact mucosa, and magnetic resonance imaging of the pelvis reveals no visible cancer or suspicious mesorectal nodes. What is the most appropriate therapy for this patient?
- A 62-year-old man was found to have 1-cm posterior rectal lesion that is 3 cm from the anal verge. Histopathologic findings are consistent with a well-differentiated adenocarcinoma without lymphovascular or perineural invasion. Magnetic resonance imaging shows that the tumor is limited to the submucosa and there are no suspicious mesorectal lymph nodes. Metastatic workup uncovers no findings. What is the most appropriate management?
- A 64-year-old man with a midrectal cancer undergoes neoadjuvant therapy and subsequent total mesorectal excision with anastomosis. After surgery, he complains of urge urinary incontinence and retrograde ejaculation. Which of the following aspects of the operative procedure are responsible for his postoperative symptoms?
- A 64-year-old man received neoadjuvant chemoradiotherapy followed by a low anterior resection 3 years ago for the treatment of rectal cancer. He complains of persistent fecal urgency, occasional fecal incontinence, clustered stools, and incomplete evacuation, which has persisted since the time of surgery. What is the most likely cause of these symptoms?
- A 53-year-old man is diagnosed with rectal adenocarcinoma 7 cm from the anal verge. Preoperative pelvic magnetic resonance imaging (MRI) demonstrates a threatened circumferential radial margin. After total neoadjuvant chemoradiation, a repeat MRI demonstrates a persistently threatened radial margin. Which of the following adjuncts should be considered in operative planning for this patient?
- A 68-year-old man with a history of a hemorrhoidectomy and fecal urgency presents with a T3n1m0 rectal cancer 5 cm from the anal verge. He has no family history of colorectal cancer. What is the most important consideration when counseling the patient about his surgical treatment options?
