Comparative Study
A defunctioning ileostomy does not prevent clinical anastomotic leak after a low anterior resection: a prospective, comparative study.
Defunctioning ileostomy or colostomy is still routinely performed after low anterior resection in the belief that diverting the fecal stream will prevent anastomotic dehiscence. However, an ileostomy is not without morbidity for the patient. This study aims to determine if a diverting stoma is really necessary after a low anastomosis. ⋯ A diverting stoma does not reduce postoperative anastomotic leak rate. Rather, it reduces the otherwise catastrophic effects of an anastomotic leak such as fecal peritonitis and septicemia. An ileostomy carries certain morbidity and also adds to the cost of the entire operation. Therefore, it should not be performed routinely. Instead, it should be performed selectively in patients with poorly prepared bowels, coupled with a distal limb washout, and in patients with significant comorbidities who can ill afford the complications of a leak.

Comparative Study
Laparoscopic-assisted vs. open ileal pouch-anal anastomosis: functional outcome in a case-matched series.
Functional outcomes in laparoscopic-assisted ileal pouch-anal anastomosis have been incompletely studied. More than one-year follow-up has rarely been reported in these patients. This study was designed to assess operative, functional, and quality of life outcomes in patients with ulcerative colitis or familial adenomatous polyposis a minimum of one year after. ⋯ The function and quality of life outcomes for patients undergoing laparoscopic-assisted ileal pouch-anal anastomosis seem to be equivalent to our open experience. Laparoscopic-assisted ileal pouch-anal anastomosis offers selected patients a safe, feasible, and durable alternative.

This study was designed to describe the consequences of diagnosis and treatment of rectal cancer for paid and unpaid labor over time and to identify sociodemographic-related factors, treatment-related factors, and quality of life-related factors associated with paid and unpaid labor. ⋯ Diagnosis and treatment of rectal cancer affect paid and unpaid labor. The impact on paid labor is most pronounced. Multiple other sociodemographic and quality of life-related variables also were associated with paid labor. Patient information and decision making on preoperative radiotherapy should include the effects on paid labor, and interventions focused on promoting paid labor participation in patients with rectal cancer should be tailored to the specific characteristics and needs of those patients.

Serum carcinoembryonic antigen elevation without detectable relapse during colorectal cancer follow-up presents a challenge. This study was designed to evaluate the utility of fluorine-18-labeled 2-fluoro-2-deoxy-D-glucose positron emission tomography in colorectal cancer patients with unexplained carcinoembryonic antigen elevation at different levels. ⋯ 2-fluoro-2-deoxy-D-glucose positron emission tomography can help triage patients for appropriate management with unexplained carcinoembryonic antigen elevation <25 ng/ml. For patients with unexplained elevation of carcinoembryonic antigen >25 ng/ml, the utility of positron emission tomography is mainly to confirm the presence of advanced disease and occasionally to identify potentially resectable lesions.

This study was designed to assess the long-term results following radiochemotherapy in patients with anal squamous-cell carcinoma and to evaluate the impact of tumor location on response, survival, and colostomy-free survival. ⋯ With colostomy-free survival rates around 85 percent, long-term treatment results for anal canal carcinoma have reached a satisfactory level. However, patients with larger lesions of the perianal skin are at high risk for locoregional recurrence and possible treatment intensification in this subgroup seems desirable.
