Comparative Study
Short- and long-term outcome following laparoscopic versus open resection for carcinoma of the rectum in the multimodal setting.
Laparoscopic resection for rectal cancer has remained controversial because of the lack of level 1 evidence regarding oncologic safety and long-term survival. ⋯ Laparoscopic surgery resulted in faster postoperative recovery and fewer long-term complications than open surgery without apparently compromising the long-term oncologic outcome. Our results indicate that laparoscopic rectal resection is an acceptable alternative to open surgery in selected patients with rectal cancer.

Sacral nerve stimulation has been reported as an effective treatment for constipation. ⋯ This study shows that sacral nerve stimulation has limited efficacy on an intention-to-treat basis as a routinely recommended therapy for intractable idiopathic constipation.

Juvenile polyposis syndrome is a dominant GI polyposis syndrome defined by ≥ 5 GI juvenile polyps or ≥ 1 juvenile polyps with a family history of juvenile polyposis. Mutations in BMPR1A or SMAD4 are found in 50% of individuals. Hereditary hemorrhagic telangiectasia is a dominant disorder characterized by epistaxis, visceral arteriovenous malformations, and telangiectasias. Hereditary hemorrhagic telangiectasia is diagnosed when ≥ 3 criteria including clinical manifestations or a family history, are present. A juvenile polyposis-hereditary hemorrhagic telangiectasia overlap syndrome has previously been reported in 22% of patients with juvenile polyposis due to a SMAD4 mutation. ⋯ Nearly all juvenile polyposis SMAD4 patients have the overlap syndrome. The clinical implications and need for hereditary hemorrhagic telangiectasia screening are important factors for genetic testing in juvenile polyposis. Health care providers must be cognizant of the juvenile polyposis-hereditary hemorrhagic telangiectasia overlap syndrome and the implications for management of these patients.

Randomized Controlled Trial Comparative Study Retracted Publication
Perianal versus endoanal application of glyceryl trinitrate 0.4% ointment in the treatment of chronic anal fissure: results of a randomized controlled trial. Is this the solution to the headaches?
Application of nitroglycerin (glyceryl trinitrate) ointment with perianal administration is a widely used treatment for chronic anal fissure. However, headache occurs after application in 20% to 70% patients and leads to withdrawal in 10% of patients. ⋯ Endoanal application significantly reduces the frequency of headaches due to treatment with 0.4% nitroglycerin ointment and results in a higher healing rate compared with perianal administration. However, roughly 1 in 4 patients still experiences headaches. Our data suggest that endoanal application may be a better option for treatment of anal fissure with nitroglycerin ointment.
