Diseases of the colon and rectum

Controversy exists over whether resection of the primary tumor in stage IV colorectal cancer with inoperable metastases improves patient outcomes. ⋯ Surgical resection of the primary tumor without metastasectomy in patients with metastatic colorectal cancer is associated with improved survival as compared with chemotherapy/radiation therapy alone. Additional research is necessary to determine which patients may benefit from this intervention.

Multicenter Study
Predicting the Risk of Bowel-Related Quality-of-Life Impairment After Restorative Resection for Rectal Cancer: A Multicenter Cross-Sectional Study.
Restorative anterior resection is considered the optimal procedure for most patients with rectal cancer and is frequently preceded by radiotherapy. Both surgery and preoperative radiotherapy impair bowel function, which adversely affects quality of life. ⋯ Before a restorative anterior resection, patients with rectal cancer should be informed that bowel-related quality-of-life impairment is common. The key risk factors are neoadjuvant therapy and a low tumor height. This study presents quality-of-life and functional outcome data, along with a consent aid, that will enhance this preoperative patient discussion.

Comparative Study
Treatment and Survival of Small-bowel Adenocarcinoma in the United States: A Comparison With Colon Cancer.
Small-bowel adenocarcinoma is rare and fatal. Because of data paucity, there is a tendency to extrapolate treatment from colon cancer, particularly in the adjuvant stetting. ⋯ The prognosis for small-bowel adenocarcinoma is worse than that for colon cancer, and only surgery improves survival. In contrast to colon cancer, a survival benefit from current chemotherapy regimens for small-bowel adenocarcinoma is not seen, suggesting that it may be overused and needs more rigorous study.

Multicenter Study Observational Study
Quality of Life and Timing of Stoma Closure in Patients With Rectal Cancer Undergoing Low Anterior Resection With Diverting Stoma: A Multicenter Longitudinal Observational Study.
After low anterior resection for rectal cancer, creation of a diverting stoma is recommended. Data on the impact of a diverting stoma on quality of life are conflicting. Optimal timing of stoma closure in the setting of adjuvant chemotherapy is unclear. ⋯ The presence of a stoma had a negative impact on social functioning and GI symptoms. However, this had no clinically relevant influence on global quality of life. Time to stoma closure was nearly doubled when patients underwent adjuvant chemotherapy.

The indications for interval elective colectomy following diverticulitis are unclear; evidence lends increasing support for nonoperative management. ⋯ Consistent with evolving practice guidelines, there has been a decrease in the use of elective colectomy following an episode of diverticulitis.
