Randomized Controlled Trial
Minilaparotomy cholecystectomy versus laparoscopic cholecystectomy: a randomized study with special reference to obesity.
Minilaparotomy cholecystectomy (MC) has recently challenged the role of the laparoscopic approach (LC) for cholecystectomies. However, the situation is far from clear when operating times and recovery are evaluated. ⋯ The MC procedure seems to be a faster technique than the LC approach for noncomplicated gallstone disease, with no difference in recovery times. The MC procedure also seems to be suitable for the obese patient.

Regional anesthesia has not been used as the sole anesthetic procedure other than in the scenario of a patient at high risk to undergo laparoscopic cholecystectomy with CO2 pneumoperitoneum under general anesthesia. ⋯ Laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum can be successfully and safely performed under spinal anesthesia. Furthermore, it seems that spinal anesthesia is associated with minimal postoperative pain and at least an equally good recovery as with general anesthesia.

The appropriateness of the laparoscopic approach for the resection of rectal cancer has been controversial, although it is well established in colon cancer. This is a phase II study of laparoscopic abdominoperineal resection (APR) in the treatment of lower rectal cancers. ⋯ In our clinical setting, laparoscopic APR can be performed with good technical efficiency, quick functional recovery, and mild disability. The short-term oncologic results of laparoscopic APR seem to be acceptable, but further long-term follow-up for these patients is mandatory to define the oncologic outcomes of this approach.

Antegrade colonic enemas offer a surgical solution for many children with chronic constipation and encopresis associated with Hirschsprung's disease and anorectal malformations. This study demonstrated the feasibility of a new laparoscopic technique for cecostomy button placement (LCBP) to allow antegrade enema treatment. ⋯ To manage overflow incontinence of children with anorectal malformations and Hirschsprung's disease, LCBP is a technically straightforward, effective, and reversible method for the placement of a cecostomy button.

Of the several million patients who undergo surgery in North America annually, a large proportion undergo intubation of the trachea. In approximately 90% of these patients, the endotracheal tube is introduced using a traditional laryngoscope with a battery in the handle and a small bulb near the tip of the blade. This bulb provides a limited and often dim view of the glottic structures. ⋯ A small TV camera with an incorporated light bundle is inserted into the handle. A wide-angle panoramic view of the upper airway anatomy is displayed on a TV screen, which can be positioned at a convenient working distance. The use of a TV monitor is a well-accepted standard during minimally invasive surgical procedures.
