To determine the effect of peridural analgesia on long-term survival in patients who underwent surgical treatment of colorectal carcinoma. ⋯ Peridural analgesia may improve survival in patients underwent surgery for colorectal carcinoma. The survival benefit with peridural analgesia was greater in patients who had greater medical morbidity.
-
To determine whether risk-adjusted colorectal SSI rates are statistically reliable as hospital quality measures. ⋯ As currently constructed, colorectal SSI quality measures might not meet a high standard of statistical reliability for most hospitals, limiting their ability to confidently differentiate high and low performance. Despite an expectation of improving statistical power, combining superficial and deep/organ-space SSI into an "any SSI" measure worsens reliability.
-
The purpose was to determine whether obesity surgery is associated with a long-term increased risk of colorectal cancer. ⋯ Obesity surgery seems to be associated with an increased risk of colorectal cancer over time. These findings would prompt evaluation of colonoscopy surveillance for the increasingly large population who undergo obesity surgery.

This study investigated the prognostic value of the new International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) lung adenocarcinoma classification in resected stage I lung adenocarcinoma. ⋯ The new adenocarcinoma classification has significant impact on death and recurrence in stage I lung adenocarcinoma. Patients with PL2 and micropapillary/solid predominant pattern have significant higher risk for recurrence. This information is important for patient stratification for aggressive adjuvant chemoradiation therapy.

To evaluate the role of sleeve gastrectomy (SG) in gastrointestinal motility. ⋯ SG accelerates gastric emptying and small bowel transit of semisolids. In addition, it delays the initiation of cecal filling and T ICVt. This early and prolonged contact of food with the distal small bowel mucosa may explain the metabolic effects of SG occurring before substantial weight loss.
