Gastroesophageal Reflux Disease

Millions of Americans are affected by gastroesophageal reflux disease (GERD) in many different ways. The magnitude of the problem of GERD was brought to light by the ambulatory pH test, the introduction of minimally invasive surgery, and the advent of the many medications that are effective in acid suppression. Patients with GERD suffer from various consequences associated with the disease. However, interventions beyond medical therapy, such as laparoscopic fundoplication, provide satisfactory outcomes and definitive relief of acid reflux.

Increasing body mass index portends abbreviated survival following pancreatoduodenectomy for pancreatic adenocarcinoma

BACKGROUND Body mass index (BMI), a common surrogate marker for grading obesity, does not differentiate between metabolically active visceral fat and the relatively inert subcutaneous fat. We aim to determine the utility of BMI as a prognostic marker for the impact of obesity on outcomes and survival following pancreatoduodenectomy for pancreatic adenocarcinoma. METHODS From a database of over 1,000 patients who had undergone pancreatoduodenectomy, 228 patients with a diagnosis of pancreatic adenocarcinoma were identified. Demographic data including BMI and perioperative parameters-operative time, estimated blood loss, length of stay, survival, nodal status, and American Joint Committee on Cancer stage-were obtained. Data are presented as median. RESULTS One hundred ninety-two patients had a BMI less than or equal to 29 and 36 patients had a BMI greater than or equal to 30 (24 vs. 34, P < .001). Median age was 70 and the majority of the patients (52%) were male and the 2 groups of patients did not differ in this regard. A significantly greater number of obese patients had positive nodes (69% vs. 62%, P < .05) and this was associated with a worse survival (14 vs. 18 months, P < .05). CONCLUSIONS For patients with pancreatic adenocarcinoma undergoing pancreatoduodenectomy, obesity does not impact operative complexity or length of stay but results in a shortened survival. Therefore, we conclude that BMI is an important prognostic marker that portends an abbreviated survival following pancreatoduodenectomy for pancreatic adenocarcinoma.
