OBJECTIVE The objective of this study was to identify potential risk factors for mortality and morbidity after distal pancreatectomy, with special focus on the formation of pancreatic fistula. SUMMARY BACKGROUND DATA Distal pancreatectomy can be performed with low mortality and acceptable morbidity rates. Pancreatic fistulas, occurring in 10% to 20% of(More)
BACKGROUND Laparoscopic cholecystectomy (LC) has been the gold standard for symptomatic gallstones for 15 years. During that time, several studies and case reports have been published which outline the possible complications of lost gallstones. The aim of this review is to categorize these complications and to evaluate the frequency and management of lost(More)
The guidelines for the management of hiatal hernia are a series of systematically developed statements to assist physicians’ and patients’ decisions about the appropriate use of laparoscopic surgery for hiatal hernia. The statements included in this guideline are the product of a systematic review of published literature on the topic, and the(More)
UNLABELLED Knowledge of the risk of lymph node metastases is critical to planning therapy for T1 esophageal adenocarcinoma. This study retrospectively reviews 75 T1a and 51 T1b tumors and correlates lymph node metastases with depth of tumor invasion, tumor size, presence of lymphovascular invasion, and tumor grade. OBJECTIVES Increasingly, patients with(More)
BACKGROUND The efficacy and safety of magnetic sphincter augmentation (MSA) with the LINX device (Torax Medical) has been reported in several short-and long-term studies, rivaling historic results of laparoscopic Nissen fundoplication (LNF), but with fewer side effects. However, there have been no studies comparing patients with similar disease to validate(More)
BACKGROUND To determine the optimal follow-up strategy after esophagectomy for adenocarcinoma of the esophagus or gastroesophageal junction by evaluating the timing of recurrence and the method that first detected the recurrence. STUDY DESIGN Between 1991 and 2007, 590 patients had an esophagectomy for adenocarcinoma. Recurrence occurred in 233 (40%) and,(More)
OBJECTIVE The aim of the study was to evaluate laser-assisted fluorescent-dye angiography (LAA) to assess perfusion in the gastric graft and to correlate perfusion with subsequent anastomotic leak. BACKGROUND Anastomotic leaks are a major source of morbidity after esophagectomy with gastric pull-up (GPU). In large part, they occur as a consequence of poor(More)
In morbid obesity conservative therapy often fails to reduce overweight permanently. As a consequence, several bariatric surgical procedures have been developed to achieve permanent excess weight loss. Among these, the laparoscopic restrictive procedures seem to be the least invasive. The aim of this prospective study was to assess and analyze the effects,(More)
Factors associated with the risk of progression of Barrett’s esophagus remain unclear, and the impact of therapy on this risk remains uncertain. The aim of this study was to assess patients followed long-term after anti-reflux surgery for Barrett’s esophagus. A retrospective review was performed of all patients with Barrett’s who underwent anti-reflux(More)
Magnetic sphincter augmentation (MSA) has emerged as an alternative surgical treatment of gastroesophageal reflux disease (GERD). The safety and efficacy of MSA has been previously demonstrated, although adequate comparison to Nissen fundoplication (NF) is lacking, and required to validate the role of MSA in GERD management. A multi-institutional(More)
