Gastric Emptying and Food Tolerance Following Banded and Non-banded Roux-en-Y Gastric Bypass.

Introduction: Gastric emptying (GE) and food tolerance (FT) can be altered after Roux-en-Y gastric bypass (RYGB) has been performed, especially when it involved the use of a restrictive mechanism (such as a silastic ring).

Aim: To assess GE and FT in patients who underwent banded (BRYGB) or non-banded Roux-en-Y gastric bypass (RYGB).

Methods: Forty-seven BRYGB patients and 47 RYGB patients underwent gastric emptying scintigraphy (GES) and FT assessment (by means of a questionnaire) between 6 months and 2 years postoperatively.

Perioperative fluorocholangiography with routine indication versus selective indication in laparoscopic cholecystectomy.

Background: The use of routine or selective peroperatory cholangiography in cholecystectomy is a matter of controversy in literature.

Aim: To compare the efficacy of selective or routine fluorocholangiography in diagnostic of common bile duct stone in patients underwent to laparoscopic cholecystectomy based on selective indication criteria.

Method: Two hundred and fifty four patients with cholelithiasis were prospectively studied.
