A retrospective multicenter analysis on redo-laparoscopic anti-reflux surgery: conservative or conversion fundoplication?

Background: Nearly 20% of patients who undergo hiatal hernia (HH) repair and anti-reflux surgery (ARS) report recurrent HH at long-term follow-up and may be candidates for redo surgery. Current literature on redo-ARS has limitations due to small sample sizes or single center experiences. This type of redo surgery is challenging due to rare but severe complications.

Risk factors for postoperative bile leakage: a retrospective single-center analysis of 411 hepatectomies.

Background: The primary focus of the study was to analyze the risk factors for bile leakage after hepatectomy for benign or malignant tumors.

Methods: A total of 411 patients who had undergone hepatectomy between December 2006 and December 2011 were retrospectively analyzed. The severity of bile leakage was graded according to the ISGLS classification.
