Short- and Long-Term Effects of Weight Loss on the Complement Component C3 After Laparoscopic Gastric Bypass in Obese Patients.

Background: The C3 complement component (C3c) is increasingly recognized as a cardiometabolic risk factor, but how it is affected after weight loss through gastric bypass is a question yet to be answered.

Methods: A total of 66 obese patients underwent laparoscopic gastric bypass. Anthropometric parameters, total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDLc), low-density lipoprotein cholesterol (LDLc), glucose, insulin, HOMA-IR, liver enzymes, high-sensitivity C-reactive protein (hsCRP), and C3c levels were evaluated at baseline and at 1 and 5 years post-surgery.

Assisted laparoscopic transhiatal esophagectomy for the treatment of esophageal cancer.

Background: Esophageal resection for the treatment of esophageal cancer is usually associated with high morbido-mortality risks, that can be reduced using laparoscopy. Laparoscopic transhiatal esophagectomy (LTE) has the potential to improve these results but, to-date, only a few limited series of cases have been reported. This report summarizes our experience in 24 cases.
