Diseases of the colon and rectum
-
Whether laparoscopic surgery for colon and rectal cancer is cost-effective in comparison with open surgery remains unclear, because laparoscopic surgery results in shorter hospital stays but is associated with increased equipment costs. ⋯ Laparoscopic resection for colon and rectal cancer results in decreased costs and equivalent quality of life, making it the preferred approach in suitable patients.

Restorative proctocolectomy with IPAA is an optimal surgical treatment for patients with familial adenomatous polyposis and therapy resistant ulcerative colitis, few data are available on long-term results in patients who have undergone this operation at a young age. ⋯ Restorative proctocolectomy with IPAA can be performed in young patients with an acceptable functional outcome, but at the cost of relatively high complication rates, poor body image and cosmesis, and a high rate of sexual dysfunction in women. Because young patients undergoing this surgical procedure may experience negative long-term effects, surgeons should be aware of all potential consequences, inform patients as to what to expect, and ensure long-term follow-up to deal with long-term complications.

Rectal dissection using a conventional multiport laparoscopic approach involves risks due to technical difficulties, particularly in patients with a low tumor, a narrow pelvis, or obesity. ⋯ Rectal resection via the transanal approach combined with single-port laparoscopic assistance may be easier and safer than the traditional approach, especially in male patients who have a narrow pelvis. More data are needed in order to draw conclusions concerning oncologic results and before selecting the most appropriate indications for this technique.

The current recommendation from the American Joint Committee on Cancer and the International Union Against Cancer is that 12 or more lymph nodes should be examined to appropriately stage rectal cancer. It is unclear if this metric is appropriate or achievable for patients who receive neoadjuvant therapy. ⋯ Patients with rectal cancer who receive preoperative chemoradiotherapy should be anticipated to have a lower lymph node yield than patients who receive surgery alone. This calls into question if the current guideline of 12 lymph nodes is relevant, in particular, for those patients receiving neoadjuvant therapy.

Laparoscopic lavage has shown promising results in nonfeculent perforated diverticulitis. It is an appealing strategy; it avoids the complications associated with resection. However, there has been some reluctance to widespread uptake because of the scarcity of large-scale studies. ⋯ The number of patients selected for laparoscopic lavage in perforated diverticulitis is increasing, and the outcomes in this study are comparable to other reports. Those patients in whom laparoscopic lavage alone was suitable had lower mortality and morbidity than those in whom resection was considered necessary.
