Laparoscopic resection for rectal cancer: outcomes in 194 patients and review of the literature.
There are few reports on laparoscopic rectum resection demonstrating its feasibility and efficacy in patients with rectal cancer. Most patient series are small, and results must be considered preliminary and medium-term. Our large prospective conducted study aimed to assess the effectiveness of a totally laparoscopic resection for rectum carcinoma with emphasis on perioperative and long-term oncological outcomes. ⋯ Our results and the literature review clearly demonstrate that laparoscopic resection for rectal cancer is not associated with higher morbidity and mortality. Established oncological and surgical principles are respected and long-term outcomes are at least as good as those after open surgery.

Performing laparoscopic surgery involves a complex cascade of cognitive skills, which may inherently have a constant technical error rate. We assess generic and specific minor and major error rates in laparoscopic cholecystectomies (LCs) performed by consultant surgeons. ⋯ Performing laparoscopic surgery may always have a background technical error rate. Our present study demonstrates a migration of surgical technical errors in expert laparoscopic surgeons. The surgeons migrate technically when they execute a high rate of procedure-specific minor errors. However, when it comes to the major fundamental aspects of the operation, they dynamically adapt and migrate away from performing major technical errors. We aim to continue the study to increase cases, assess trainees as well, and also explore other factors that may affect the surgeon when executing surgical technical tasks.

The purpose of this study was to examine the influence of patient and hospital demographics on cholecystectomy outcomes. ⋯ Patient and hospital demographics do affect the outcomes of patients undergoing inpatient cholecystectomy. Although male gender, African American race, Medicare-insured status, and large, urban hospitals are associated with less favorable cholecystectomy outcomes, only increased age predicts increased morbidity, whereas female gender, laparoscopy, and cholangiogram are protective. Increased age, complications, and emergency surgery predict mortality, with laparoscopy and intraoperative cholangiogram having protective effects.

Median arcuate ligament syndrome is a rare disorder resulting from luminal narrowing of the celiac artery by the insertion of the diaphragmatic muscle fibers or fibrous bands of the celiac nervous plexus. The syndrome is characterized by weight loss, postprandial abdominal pain, nausea, vomiting, and an epigastric bruit. Surgical management entails complete division of the median arcuate ligament. ⋯ The patient was discharged on postoperative day 3 and remained asymptomatic after 7 months of follow-up. Laparoscopic release of the median arcuate ligament is a novel approach to the management of celiac artery compression syndrome. The role of minimally invasive techniques to manage median arcuate ligament syndrome is evolving but they appear to be a safe alternative to open surgery.

Because of the growing interest in surgery to treat morbid obesity, this study examined changes in the utilization and in-hospital outcomes of bariatric surgery in the United States over a 10-year period. ⋯ The annual rate of bariatric surgery in the United States increased nearly six fold between 1990 and 2000, with little change in in-hospital morbidity and mortality. This appears to be driven largely by the increasing popularity of gastric bypass procedures.
