To evaluate the safety and outcome of multivisceral pancreatic resections for primary pancreatic malignancies. ⋯ Multivisceral resections can be performed with increased morbidity but comparable mortality and long-term prognosis as compared with standard pancreatic resections at high volume centers. Increased morbidity is related to extended multivisceral resections with a long operative time.

The obesity paradox: body mass index and outcomes in patients undergoing nonbariatric general surgery.
We sought to examine the effect of body mass index (BMI) on 30-day morbidity and mortality in a large cohort of patients undergoing nonbariatric general surgery. ⋯ Overweight and moderately obese patients undergoing nonbariatric general surgery have paradoxically "lower" crude and adjusted risks of mortality compared with patients at a "normal" weight. This finding is in contrast to observations from the general population, confirming the existence of an "obesity paradox" in this patient population.

Comparative Study
Bowel obstruction following appendectomy: what is the true incidence?
Appendicitis is a common problem that is typically treated with an appendectomy. Following abdominal surgery, adhesions may form and may cause a subsequent small bowel obstruction (SBO). The purpose of our study was to determine the rate of post-appendectomy SBO in an adult population, and to observe any difference in SBO rates between open versus laparoscopic appendectomies. ⋯ The rate of SBO following appendectomy in adults was 2.8%, or 0.0069 cases per person-year. The greatest risk factors for developing SBO were midline incision and nonappendicitis pathology. There is no statistically significant difference in SBO rates following laparoscopic appendectomy compared with open approaches.

The goal was to assess long-term oncologic outcome after laparoscopic versus open surgery for rectal cancer and to evaluate the impact of conversion. ⋯ The efficacy of laparoscopic surgery in a team specialized in rectal excision for cancer (open and laparoscopic surgery) is suggested with similar long-term local control and cancer-free survival than open surgery. Moreover, conversion had no negative impact on survival.

Randomized Controlled Trial Comparative Study
Preliminary results of a prospective randomized trial of restrictive versus standard fluid regime in elective open abdominal aortic aneurysm repair.
Open abdominal aortic aneurysm (AAA) repair is associated with a significant morbidity (primarily respiratory and cardiac complications) and an overall mortality rate of 4% to 10%. We tested the hypothesis that perioperative fluid restriction would reduce complications and improve outcome after elective open AAA repair. ⋯ Serious complications are common after elective open AAA repair, and we have shown for the first time that a restricted perioperative fluid regimen can prevent MC and significantly reduce overall hospital stay.
