Meta AnalysisMeta-analysis of randomized controlled trials comparing laparoscopic and open appendectomy.
We performed a meta-analysis to determine whether laparoscopic or open appendectomy gives better outcomes for patients with suspected acute appendicitis. Studies were selected from the MEDLINE database, personal files, and meeting abstracts. Eleven of 21 randomized controlled trials were included in the meta-analysis. ⋯ Operating time was increased by 17.12 min (95% CI 14.19 to 20.03; p < 0.0001). There was no difference between the two surgeries for length of hospital stay, readmission rate, and intra-abdominal abscess formation. Laparoscopic appendectomy improves patient outcomes.

Randomized Controlled Trial Comparative Study Clinical TrialIntraperitoneal normal saline and bupivacaine infusion for reduction of postoperative pain after laparoscopic cholecystectomy.
After laparoscopic cholecystectomy, CO2 remains within the peritoneal cavity, commonly causing pain. This prospective randomized study was performed to determine the efficacy of intraperitoneal normal saline and bupivacaine infusion on postoperative pain after laparoscopic cholecystectomy. Three hundred patients were randomly assigned to one of six groups of 50 patients each. ⋯ Postoperative pain was reduced significantly in the patients of the treatment groups vs. the controls. Between treatment groups, patients in groups B, E, and F had the best results, while those in groups C and D had significantly greater pain than those in groups B, E, and F. It is concluded that postoperative pain after laparoscopic cholecystectomy can be significantly reduced by intraperitoneal normal saline infusion subdiaphragmatically and after its postdeflation suction, bupivacaine infusion in the same area, or without bupivacaine in case a subhepatic drainage has been needed.

Randomized Controlled Trial Comparative Study Clinical TrialStress hyperglycemia in minimally invasive surgery.
This study examined the selected hormonal responses to, and hormone-mediated glucose metabolism during minimally invasive surgery in, patients undergoing laparoscopic cholecystectomy for symptomatic gallstone disease. Thirty-two patients with symptomatic gallstone disease were included in this study and scheduled for open or laparoscopic procedure in a randomized trial. Results are expressed as mean and standard error of the mean. ⋯ The glucagon-mediated increase in hepatic glucose production is excluded by the posttraumatic insulin levels from the insulin-sensitive tissues. A bihormonal setting favors a greater rate of hepatic glucose production in both open and laparoscopic surgery. Hormonal changes do reflect the degree of surgical stress, but their metabolic consequences are not parallel to the grade of surgical trauma in minimally invasive surgery.

Case ReportsSuspected appendicitis in situs inversus totalis: an indication for a laparoscopic approach.
We report a case of acute appendicitis in situs inversus treated by laparoscopy. In our opinion, diagnostic laparoscopy is indicated if acute appendicitis is suspected in a patient with situs inversus totalis, either because the pain can be referred to the right iliac fossa in about 50% of the patients, or because the incision in open surgery cannot be sufficient to allow complete exploration of the abdomen. The operation can then be carried out laparoscopically if possible; if not, an appropriate surgical incision can be made.

We report on thoracoscopic plication of the the paralyzed right hemidiaphragm of a 33-year-old woman with a history of reactive airway disease. The paralysis was secondary to transection of the phrenic nerve during right first rib resection for thoracic outlet syndrome 1 year prior to evaluation. ⋯ Postoperative recovery was uneventful, with minimal pain and early discharge. Preoperative symptoms of exertional dyspnea and orthopnea were significantly improved.
