Multicenter Study Clinical Trial
Prevalence of adverse intraoperative events during obesity surgery and their sequelae.
Adverse intraoperative events (AIEs) during surgery are a well-known entity. A better understanding of the incidence of AIEs and their relationship with outcomes is helpful for surgeon preparation and preoperative patient counseling. The goals of this study are to describe the incidence of AIEs during bariatric surgery and examine their impact on major adverse complications. ⋯ Incidence of an AIE is not infrequent during bariatric surgery and is associated with much higher risk of major complication. Additional study is needed to assess the association between specific AIEs and short-term complications.

Multicenter Study
Liver resection for hepatocellular carcinoma ≤3 cm: results of an Italian multicenter study on 588 patients.
The best treatment for patients with small hepatocellular carcinoma (S-HCC) is still controversial. The aim of this study was to evaluate operative and long-term results after liver resection (LR) for S-HCC, defined as tumor ≤3 cm. ⋯ Liver resection for S-HCC has improved over the years, with decreased operative risk. Long-term survival after LR has increased. Despite small tumor size, rates of microsatellite nodules and microvascular invasion are not negligible. Presence of microsatellite lesions was the only variable identified as being associated with poor both OS and DFS.
