Do colorectal cancer resections improve diabetes in long-term survivors? A case-control study.

Background: A clinical study was designed that aimed to analyze whether resection of the large bowel in cancer patients might benefit diabetes mellitus.

Methods: This prospective case-control study included retrospective information. Patients (n = 247) included diabetic and euglycemic groups with colorectal cancer operations (n = 60), cancer gastrectomy (n = 72), exclusive chemoradiotherapy for rectal cancer (n = 46), and noncancer clinical controls (n = 69).

Does Roux-en-Y gastrectomy for gastric cancer influence glucose homeostasis in lean patients?

Background: Cancer gastrectomy seems to benefit type 2 diabetes; however, results are conflicting. In a prospective protocol, including retrospective information, the aim was assessment of changes in glucose profile in patients with both normal and deranged preoperative glucose homeostasis.

Methods: Patients (N = 164) with curative subtotal or total Roux-en-Y gastrectomy for gastric cancer (n = 92), or Roux-en-Y gastric bypass for morbid obesity (RYGB, n = 72) were preoperatively classified into diabetes (including prediabetes) and control group.

Refractory and new-onset diabetes more than 5 years after gastric bypass for morbid obesity.

Background: Few studies about long-term glucose homeostasis in bariatric patients are available. In a prospective protocol that included retrospective information, outcome of patients with both impaired and normal fasting blood glucose (FBG) was monitored to assess frequencies and correlates.

Methods: Patients submitted to Roux-en-Y gastric bypass were classified as group I, elevated FBG, and group II, normal controls.

Interference of silicone breast implants on bioimpedance measurement of body fat.

Background: No study targeting the impact of silicone breast implants on body composition measured by bioimpedance analysis was identified.

Objective: Aiming to clarify this question a prospective clinical study was designed.

Methods: Adult candidates were submitted to conventional analysis at baseline and two months after the surgical intervention.

Four-year hospital resource utilization after bariatric surgery: comparison with clinical and surgical controls.

Background: Consumption of healthcare has been shown to diminish after bariatric treatment, but utilization of hospital services has not been well documented. Aiming to assess this question, a retrospective study with females was designed.

Methods: Yearly outpatient appointments, hospital admissions, emergency department visits, and total biochemical tests during 4 years were registered and compared with the preoperative year.
