Randomized Controlled Trial Clinical Trial
Preincisional local anesthesia with bupivacaine and pain after laparoscopic cholecystectomy. A double-blind randomized clinical trial.
The aim of this study was to investigate whether local anesthesia of abdominal wall wounds prior to laparoscopic cholecystectomy leads to decreased pain beyond the immediate postoperative period and thus improves the comfort of the patient. In a randomized, double-blind study 50 patients scheduled for laparoscopic cholecystectomy were divided into two groups. In one group (n = 25) the skin, subcutis, fascia, muscle, and preperitoneal space were infiltrated with 8 ml of bupivacaine 0.5% 5 min before each abdominal wall incision. ⋯ Similar statistically nonsignificant results were found for the mean consumption of piritramide up to 16 h after the operation. Three patients (12%) in the bupivacaine group localized the most severe pain up to the second postoperative day to the right lower abdominal wall wound where the gallbladder had been extracted compared to 11 patients (44%) of the control group (P = 0.012). These results indicate that bupivacaine was effective at the site where it was administered.(ABSTRACT TRUNCATED AT 250 WORDS)

The advent of the laparoscopic revolution and the wider applicability of laparoscopic procedures has caused surgeons to re-think the dynamics of intraoperative problem-solving. Problems of body habitus, previous surgery, exposure, bleeding, and anesthesia, as well as the problem cholangiogram, require new and innovative approaches, a practical approach to each of these common laparoscopic problems is presented.

The virtual-reality surgical simulator signals the beginning of an era of computer simulation for surgery. The surgical resident of the future will learn new perspectives on surgical anatomy and repeatedly practice surgical procedures until they are perfect before performing surgery on patients. ⋯ It is anticipated that the full development of the surgical simulator will take less than the 40 years which was required for flight simulators to become an indispensable ingredient of pilot training. As the system evolves, many new and yet-to-be-imagined applications will arise, but we must have understanding and patience as we wait for computer power to improve to a point where VR surgical simulation can emerge from its PacMan era.

Traditional operative management for chylous drainage refractory to conservative therapy is thoracic duct ligation via right open thoracotomy. This case report details successful thoracoscopic ligation of the thoracic duct for a chylous leak following a left neck dissection. Since the thoracoscopic approach is less morbid than open thoracotomy, early operative management is recommended for thoracic duct injuries.

The prevention of anesthetic mishaps during endoscopic procedures is of great importance to physicians in training. With the large number of such procedures performed each year, even infrequent adverse anesthetic reactions may result in a significant number of problems. To establish the safety and efficacy of an anesthetic regimen using intravenous meperidine and diazepam, all endoscopic procedures performed at one teaching institution in a 4-month period were retrospectively analyzed with regard to: (1) type and dosage of sedation/anesthesia, (2) endoscopic procedure involved, (3) effect of any underlying disease state, (4) side effects, (5) endoscopic complications, and (6) overall patient acceptance. ⋯ The adult dose remained constant for the next eight decades of life (meperidine 0.76 +/- 0.33 mg/kg: diazepam 0.12 +/- 0.08 mg/kg). In the adult group, 758 procedures were performed: 371 patients underwent esophago-gastroduodenoscopy, 258 colonoscopy, 36 endoscopic retrograde cholangiopancreatography, 40 flexible sigmoidoscopy, and 51 percutaneous endoscopic gastrostomy. Anesthetic-related complications (transient apnea and itching), were noted in two patients, and naloxone was utilized to reverse oversedation in a further 17 (2.56%).(ABSTRACT TRUNCATED AT 250 WORDS)
