Comparative StudyPancreaticoduodenectomy: role of interventional radiologists in managing patients and complications.
Although the mortality rate after pancreaticoduodenectomy has decreased, the morbidity rate remains high. Major morbidity is often managed with the aid of interventional radiologists. The objective of this study was to evaluate the cooperative roles of interventional radiologists and pancreatic surgeons in complex pancreatic surgery, specifically pancreaticoduodenectomy. ⋯ The median postoperative length of stay was 15 days in those patients requiring postoperative radiologic intervention, 10 days in those not requiring intervention (P < 0.01; postoperative interventional radiology vs. no postoperative interventional radiology), and 29.5 days for patients needing reoperation. Interventional radiologists play a critical role in the management of some patients undergoing pancreaticoduodenectomy. Although complications such as anastomotic leaks, abscess formation, and bleeding can result in increased mortality and a longer hospital stay, the skills of the interventional radiology team provide expert management of some life-threatening complications, thus avoiding reoperation, speeding recovery times, and minimizing morbidity.

A 1991 National Institutes of Health Consensus Conference concluded that severely obese adults could be eligible for bariatric surgery if they had a body mass index (BMI) > or =35 kg/m(2) with or > or =40 kg/m(2) without obesity comorbidity. It was thought at that time that there were inadequate data to support bariatric surgery in severely obese adolescents. An estimated 25% of children in the United States are obese, a number that has doubled over a 30-year period. ⋯ Severe obesity is increasing rapidly in adolescents and is associated with significant comorbidity and social stigmatization. Bariatric surgery in adolescents is safe and is associated with significant weight loss, correction of obesity comorbidity, and improved self-image and socialization. These data strongly support obesity surgery for those unfortunate individuals who may have difficulty obtaining insurance coverage based on the 1991 National Institutes of Health Consensus Conference statement.

Intestinal hypoperfusion contributes to gut barrier failure in severe acute pancreatitis.
Intestinal barrier failure and subsequent bacterial translocation have been implicated in the development of organ dysfunction and septic complications associated with severe acute pancreatitis. Splanchnic hypoperfusion and ischemia/reperfusion injury have been postulated as a cause of increased intestinal permeability. The urinary concentration of intestinal fatty acid binding protein (IFABP) has been shown to be a sensitive marker of intestinal ischemia, with increased levels being associated with ischemia/reperfusion. ⋯ Furthermore, the control group had significantly lower IFABP-c (median 37 pg/ml; P = 0.029) and IFABP-t (median 0.06 microg; P = 0.005) than patients with mild attacks. IFABP correlated positively with the polyethylene glycol 3350 percentage retrieval (r = 0.50; P < 0.001), CRP (r = 0.51; P < 0.001), and inversely with serum IgM EndoCAb levels (r = -0.32; P = 0.02). The results of this study support the hypothesis that splanchnic hypoperfusion contributes to the loss of intestinal mucosal integrity associated with a severe attack of pancreatitis.

Comparative StudyPortal vein embolization vs. portal vein ligation for induction of hypertrophy of the future liver remnant.
The objective of this study was to assess the efficacy of right portal vein embolization (PVE) vs. right portal vein ligation (PVL) for induction of hypertrophy of the left lateral liver lobe before extended right hepatectomy. Thirty-four patients with primary or secondary liver tumors and estimated remnant functional liver parenchyma of less than 0.5% of body weight underwent either right PVE (transcutaneous, n = 10; transileocolic, n = 7) or right PVL (n = 17). Liver volume was assessed by CT scan before occlusion of the right portal vein and prior to resection. ⋯ Curative liver resection was performed in 10 of 17 patients after PVE and 11 of 17 patients after PVL. PVE and PVL were found to be feasible and safe methods of increasing the remnant functional liver volume and achieving resectability for extended liver tumors. PVE results in a significantly more efficient increase in liver volume and a shorter hospital stay.

Randomized Controlled Trial Clinical TrialLong-term efficacy of total (Nissen-Rossetti) and posterior partial (Toupet) fundoplication: results of a randomized clinical trial.
The efficacy of fundoplication operations in the long-term management of gastroesophageal reflux disease (GERD) has been documented. However, only a few prospective controlled series support the long-term (>10 years) efficacy of these procedures, and further data are required to also determine whether the type of fundoplication affects the frequency of postfundoplication complaints. The aim of this study was to conduct a randomized, controlled clinical trial to assess the long-term symptomatic outcome of a partial posterior fundoplication as compared to a total fundic wrap. ⋯ On the other hand, a significant difference was observed in the prevalence of rectal flatus and postprandial fullness, which were recorded significantly more often in those undergoing a total fundoplication (P < 0.001 and P < 0.03, respectively). Posterior partial fundoplication seems to maintain the same high level of reflux control as total fundoplication. Earlier observations demonstrating the advantages of a partial fundoplication, which included fewer complaints associated with gas-bloat, continue to be valid after more than 10 years of follow-up.
