The deleted in colorectal cancer (DCC) gene predicts a poor outcome for patients with colorectal carcinoma. This study was designed to investigate whether the expression of the DCC protein also can predict response to adjuvant chemotherapy. ⋯ DCC is a prognostic factor for colorectal cancer. Positive expression of DCC identifies a subgroup of patients who respond favorably to adjuvant chemotherapy, which resulted in our cases, in 100 percent survival and disease-free survival rates. Without treatment, the survival rate of DCC+ patients dropped significantly. We suggest that DCC immunostaining should be performed routinely. All DCC+ patients should receive adjuvant chemotherapy. For DCC- tumors, a larger cohort of patients should be studied before definitive conclusions can be drawn; however, clinical trials of new drug combinations should focus on DCC- patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Carbohydrate-electrolyte (E-Lyte) solution enhances bowel preparation with oral fleet phospho-soda.
Bowel preparation with oral sodium phosphate can cause symptomatic dehydration and electrolyte disturbances. This randomized, controlled trial was designed to evaluate whether carbohydrate-electrolyte (E-Lyte) solution enhanced bowel preparation and improved patient acceptance with oral sodium phosphate. ⋯ Carbohydrate-electrolyte (E-Lyte) solution protects against hypokalemia, improves patient tolerability, and may enhance use of oral sodium phosphate as a bowel-preparation agent.

Randomized Controlled Trial Clinical Trial
Topical metronidazole (10 percent) decreases posthemorrhoidectomy pain and improves healing.
Oral metronidazole has been previously demonstrated to decrease postoperative pain after open diathermy hemorrhoidectomy. The current study investigates the efficacy of topical metronidazole (10 percent) in reducing postoperative pain and promoting wound healing after Harmonic Scalpel hemorrhoidectomy. ⋯ Topical 10 percent metronidazole significantly reduces posthemorrhoidectomy discomfort at days 7 and 14 postoperatively. Postoperative edema is reduced and overall healing is improved, compared with that of carrier controls.

Comparative Study
Colonic surgery with accelerated rehabilitation or conventional care.
For patients undergoing colonic surgery, the postoperative hospital stay is usually 6 to 10 days, and the morbidity rate is 15 to 20 percent. Fast-track rehabilitation programs have reduced the hospital stay to 2 to 3 days. The aim of this study was to evaluate the postoperative outcome after colonic resection with conventional care compared with fast-track multimodal rehabilitation. ⋯ Time to first defecation, hospital stay, and morbidity may be reduced after colonic resection with fast-track multimodal rehabilitation.

Constipation is a commonly reported symptom, and pelvic floor dyssynergia is frequently documented in constipated patients. The standard therapeutic approach for pelvic floor dyssynergia is biofeedback training, but long-term studies show that a significant percentage of patients remain symptomatic. Alternative or adjunctive therapeutic options are needed. ⋯ Because of the relatively simple, painless and effective nature of electrogalvanic stimulation, we concluded that it may represent a useful adjunct to the therapeutic armamentarium for pelvic floor dyssynergia in normal transit constipation.
