Obesity is associated with an increased risk of postoperative complications after colectomy for cancer, but it is unclear which specific complications occur more frequently in obese patients. Our objective was to assess the association of body mass index (BMI) on short-term outcomes after colectomy for cancer. ⋯ Compared with normal weight patients, morbidly obese patients had a higher risk of surgical site infection, dehiscence, pulmonary embolism, and renal failure, but not other complications or mortality. Quality initiatives should include these specific complications.

The outcomes after elective surgery in patients with cirrhosis have not been well studied. ⋯ In-hospital mortality, length of stay, and total hospital charges are significantly higher after elective surgery in cirrhotic patients, even in the absence of portal hypertension. Careful decision-making about surgery in these patients is critical as the nationwide increase in hepatitis C and cirrhosis continues.

Anastomotic leak is a dreaded complication of intestinal surgery and has been associated with a high mortality rate. But it is uncertain exactly which patient populations are at risk of death from the leak. We sought to assess the impact of surgeon volume on leak rate and to better understand the relationship of a leak to postoperative mortality. ⋯ The variability in leak rate by surgeons doing similar operations suggests that many leaks may be preventable. But death after a leak is most often a surrogate for a critically ill patient and was infrequently the actual cause of death.

Recent studies suggest that preoperative cardiac stress testing is unnecessary in low to intermediate cardiac risk patients undergoing operations, and that targeted beta blockade is cardiac protective. ⋯ In patients undergoing vascular surgery or major amputation, with low to intermediate cardiac risk, preoperative targeted beta blockade alone is more effective than selective cardiac stress testing and nontargeted beta blockade in preventing cardiac morbidity.

Surgery remains the standard for nonmetastatic gastrointestinal stromal tumors (GISTs). Laparoscopic surgery should be considered for these tumors, because their biologic behavior lends them to curative resection without requiring large margins or extensive lymph-adenectomies. ⋯ Laparoscopic resection of GISTs is considered safe and effective. The longterm disease-free survival of 78% establishes this minimally invasive approach as comparable to open techniques.
