Colonoscopy is a proven method for bowel cancer screening and is often experienced as a painful procedure. Today, there are two main strategies to facilitate colonoscopy. First, deep sedation results in satisfied patients but increases sedation-associated risks and raises costs for healthcare providers. ⋯ There are two agents, with the potential to be a nearly ideal analgesic agent for colonoscopy: alfentanil and nitrous oxide (N(2)O). Administration of either substance causes the patient to be comfortable yet alert and facilitates a short turnover. Advantages of these drugs include rapid onset and offset of action, analgesic and anxiolytic effects, ease of titration to desired level, rapid recovery, and an excellent safety profile.

The aim of this study was to evaluate the outcomes of an early stoma closure protocol facilitated by Seprafilm wrapping of defunctioning ileostomies compared with a similar group of patients with conventional stoma formation and closure. ⋯ An early stoma closure protocol facilitated by Seprafilm wrapping of the ileostomy is practical, does not increase morbidity and significantly reduces the time with a stoma for the patient. An early stoma closure protocol did not significantly delay in the commencement of chemotherapy.

The Pfannenstiel incision, widely used in gynecological surgery, has been reported to be associated with lower rates of wound complications than midline incisions in open surgery. However, its effect on wound complications in minimally invasive surgery (MIS) is not well understood. We hypothesize that use of a Pfannenstiel incision in MIS colorectal cancer resections would be associated with fewer short-term wound complication rates. ⋯ The use of a Pfannenstiel incision in MIS colorectal cancer resections is associated with a decreased risk of short-term wound complications.

Pilonidal sinus disease (PSD) is a common problem in surgical practice. Different non-surgical and surgical methods have been used for treating PSD. Flap techniques including the Limberg flap have become more popular in recent years. A modified Limberg flap was used to reduce the problems of skin maceration and recurrence associated with the conventional Limberg flap technique. The aim of this retrospective study was to assess the effectiveness of the modified Limberg flap technique for PSD. ⋯ When compared with the available data on use of the conventional Limberg flap for PSD, our results suggest that use of the modified Limberg flap is associated with a lower maceration and recurrence rate, and greater patient satisfaction.

Randomized Controlled Trial Comparative Study
Doppler-guided hemorrhoidal artery ligation does not offer any advantage over suture ligation of grade 3 symptomatic hemorrhoids.
Doppler-guided ligation of hemorrhoidal vessels is being proposed as a treatment of grade 2 and 3 hemorrhoids. Many researchers are coupling this procedure with mucopexy or lifting of hemorrhoids to control the prolapse more effectively. The present study was conducted in patients with 3rd-degree hemorrhoids to determine the usefulness of Doppler-guided hemorrhoidal artery ligation compared to mucopexy of prolapsing hemorrhoids and to compare it with mere mucopexy of the hemorrhoids. ⋯ Suture ligation of hemorrhoids is a simple, cost-effective, and convenient modality for treating grade 3 hemorrhoids. Doppler assistance in ligating the hemorrhoidal vessels prior to hemorrhoidal mucopexy offers no advantage and is a time-consuming procedure.
