Randomized Controlled Trial Multicenter Study Comparative Study
Randomized, multicenter trial of antibiotic prophylaxis in elective colorectal surgery: single dose vs 3 doses of a second-generation cephalosporin without metronidazole and oral antibiotics.
Use of prophylactic antibiotics in elective colorectal surgery is essential. Although single-dose prophylactic antibiotics are recommended, the efficacy of single-dose cephalosporin without metronidazole and oral antibiotics is not fully proven. We conducted a multicenter, randomized trial of a single dose vs 3 doses of the second-generation cephalosporin cefmetazole. ⋯ Three-dose cefmetazole administration is significantly more effective for prevention of incisional SSI than single-dose antibiotic administration.

LigaSure vs clamp-and-tie technique to achieve hemostasis in total thyroidectomy for benign multinodular goiter: a prospective randomized study.
Occurrence of adverse effects and advantages of the LigaSure diathermy system (or LigaSure vessel sealing system) in total thyroidectomy have not been tested in prospective randomized studies comparing its use with that of the time-saving clamp-and-tie technique to ligate and divide thyroid vessels. The effectiveness of LigaSure in achieving vessel division and hemostasis remains dependent on vessel diameter, and the risk of damage to adjacent structures cannot be completely excluded. We tested the hypothesis that use of LigaSure compared with the clamp-and-tie technique can significantly and conveniently reduce operative time without increasing postoperative complications in patients undergoing total thyroidectomy for benign multinodular goiter. ⋯ The use of LigaSure is equally as safe and effective at vessel division and homeostasis as the clamp-and-tie technique, with a statistically significant (although minimal) decrease in mean operative time. Because of this minimal decrease in operative time, use of LigaSure would allow more patients to undergo total thyroidectomy each year, which would eventually help to offset its higher cost.

Randomized Controlled Trial
Molgramostim (GM-CSF) associated with antibiotic treatment in nontraumatic abdominal sepsis: a randomized, double-blind, placebo-controlled clinical trial.
The addition of molgramostim (recombinant human granulocyte-macrophage colony-stimulating factor) to antibiotic therapy for nontraumatic and generalized abdominal sepsis is effective and has a significant impact on length of hospitalization, direct medical costs, and mortality. ⋯ Addition of molgramostim to antibiotic therapy reduces the rate of infectious complications, the length of hospitalization, and costs in patients with nontraumatic abdominal sepsis.

Local Anesthesia With Monitored Anesthesia Care vs General Anesthesia in Thyroidectomy: A Randomized Study.
Early in the 20th century, thyroid surgery was performed using local anesthetic techniques. When general anesthesia became safer, surgeons started performing thyroidectomy exclusively under general anesthesia. However, recent descriptions of thyroidectomy under local anesthesia claim similar results to thyroidectomy under general anesthesia. Surgery conducted under local anesthesia can result in early discharge, ie, a hospital stay of less than 8 hours. ⋯ Thyroidectomy can be performed in the studied patient population under either general anesthesia or local anesthesia with MAC, expecting similar operative results, clinical results, and patient satisfaction. In addition, local anesthesia with MAC can reduce the postoperative time spent in an outpatient surgery setting with potential health care cost savings.

Randomized Controlled Trial Comparative Study
Advantages of mini-laparoscopic vs conventional laparoscopic cholecystectomy: results of a prospective randomized trial.
The use of smaller instruments during laparoscopic cholecystectomy (LC) has been proposed to reduce postoperative pain and improve cosmesis. However, despite several recent trials, the effects of the use of miniaturized instruments for LC are not well established. We hypothesized that LC using miniports (M-LC) is safe and produces less incisional pain and better cosmetic results than LC performed conventionally (C-LC). ⋯ Laparoscopic cholecystectomy can be safely performed using 10-mm umbilical, 5-mm epigastric, 2-mm subcostal, and 2-mm lateral ports. The use of mini-laparoscopic techniques resulted in decreased early postoperative incisional pain, avoided late incisional discomfort, and produced superior cosmetic results. Although improved instrument durability and better optics are needed for widespread use of miniport techniques, this approach can be routinely offered to many properly selected patients undergoing elective LC.
