Comparative Study
Survival and changes in comorbidities after bariatric surgery.
To evaluate survival rates and changes in weight-related comorbid conditions after bariatric surgery in a high-risk patient population as compared with a similar cohort of morbidly obese patients who did not undergo surgery. ⋯ Bariatric surgery appears to increase survival even in the high-risk, Medicare population, both for individuals aged 65 and older and those disabled and under 65. In addition, the diagnosed prevalence of weight-related comorbid conditions declined after bariatric surgery relative to a control cohort of morbidly obese patients who did not undergo surgery.

To determine the accuracy of plain abdominal radiographs in the detection of retained surgical needles of varying size in the peritoneal cavity. ⋯ Abdominal radiographs have high sensitivity and interobserver agreement in the detection of retained surgical needles over 10 mm in length, but smaller needles are detected with significantly lower sensitivity and the utility of plain abdominal radiographs in this setting is more debatable.

Meta Analysis
The rupture rate of large abdominal aortic aneurysms: is this modified by anatomical suitability for endovascular repair?
There are no precise estimates of the rate of rupture of large abdominal aortic aneurysms (AAA). There is recent suspicion that anatomic suitability for endovascular repair may be associated with a decreased risk of AAA rupture. ⋯ Rupture rates of large AAAs reported in different studies are highly variable. There is emerging evidence that patients anatomically suitable for endovascular repair have lower rupture rates.

Randomized Controlled Trial
Randomized trial of division versus nondivision of the short gastric vessels during laparoscopic Nissen fundoplication: 10-year outcomes.
Although laparoscopic Nissen fundoplication is an effective procedure for the treatment of gastroesophageal reflux, in some patients it is followed by troublesome side effects, such as dysphagia, abdominal bloating, and inability to belch. It has been claimed that dividing the short gastric blood vessels during laparoscopic Nissen fundoplication minimizes the risk of these problems. We have previously reported the 6-month and 5-year outcomes from a randomized trial, which have shown no advantages after division of these vessels. In this study, we determined the longer-term (10 years) outcomes from this trial. ⋯ The 10-year clinical outcomes from this trial have shown no benefit for division of the short gastric vessels during laparoscopic Nissen fundoplication.

Randomized Controlled Trial
Adjuvant intra-arterial iodine-131-labeled lipiodol for resectable hepatocellular carcinoma: a prospective randomized trial-update on 5-year and 10-year survival.
In this prospective randomized trial, we attempted to find out if 1 dose of postoperative adjuvant intra-arterial iodine-131-labeled lipiodol could reduce the rate of local recurrence, and increase disease-free and overall survival for patients with hepatocellular carcinoma (HCC). This study evaluated the long-term outcome. ⋯ In patients with HCC, adjuvant intra-arterial I-lipiodol after curative liver resection provided survival benefit on the disease-free survival and overall survival, although the difference became statistically insignificant at 8 years after randomization.
