To determine the optimal number of lymph nodes to examine for accurate staging of node-negative pancreatic adenocarcinoma after pancreaticoduodenectomy. ⋯ Examination of 15 lymph nodes appears to be optimal to accurately stage node-negative adenocarcinoma of the pancreas after pancreaticoduodenectomy. Furthermore, evaluation of at least 15 lymph nodes of a pancreaticoduodenectomy specimen may serve as a quality measure in the treatment of pancreatic adenocarcinoma.

Comparative Study
Testing for substance use in trauma patients: are we doing enough?
Only a fraction of trauma patients are being tested for substance use, and the proportion of those tested may have decreased over time. ⋯ Only a small proportion of patients who are admitted with injuries are tested for substance use. The proportion of patients tested for drugs has decreased significantly during the past 6 years. Routine testing would maximize identification of patients who may benefit from interventions. Several obstacles exist to routine screening, including legal and physician-related barriers. Future efforts to facilitate routine testing of trauma patients for substance use should concentrate on protecting patient confidentiality and educating physicians on the techniques and benefits of brief interventions.

Randomized Controlled Trial Multicenter Study Comparative Study
Randomized, multicenter trial of antibiotic prophylaxis in elective colorectal surgery: single dose vs 3 doses of a second-generation cephalosporin without metronidazole and oral antibiotics.
Use of prophylactic antibiotics in elective colorectal surgery is essential. Although single-dose prophylactic antibiotics are recommended, the efficacy of single-dose cephalosporin without metronidazole and oral antibiotics is not fully proven. We conducted a multicenter, randomized trial of a single dose vs 3 doses of the second-generation cephalosporin cefmetazole. ⋯ Three-dose cefmetazole administration is significantly more effective for prevention of incisional SSI than single-dose antibiotic administration.

Comparative Study
Increased hospital morbidity among trauma patients with diabetes mellitus compared with age- and injury severity score-matched control subjects.
We hypothesized that patients with diabetes mellitus (DM) have worse outcomes following trauma compared with patients without a history of DM. ⋯ Patients with DM exposed to trauma have greater hospital morbidity resulting from longer intensive care unit stay, increased ventilator support, and more complications.

Stents for palliation of obstructive metastatic colon cancer: impact on management and chemotherapy administration.
The more rapid and less complicated recovery after palliative stent insertion compared with surgery may theoretically facilitate the early administration of chemotherapy. ⋯ Insertion of SEMS should be the first step to treat obstructing colon cancer with nonresectable synchronous metastases because it allows chemotherapy to be administered earlier, may increase the resectability rate of metastases, and favorably impacts survival. The risk of tumor perforation while receiving chemotherapy requires attention.
