These findings suggest that morbid obesity is associated with vitamin D deficiency, and elevated PTH and with adequate supplementation, GBP, and particularly LAGB, patients can improve their bone metabolism abnormalities related to obesity. Furthermore, adequate supplementation for GBP patients may attenuate the increased risk for bone loss associated with malabsorption from the bypass.
These data from a large, unselected group of thyroidectomy patients suggest LA results in similar outcomes and morbidity rates to GA. It is likely that associated LA costs are lower.
These results indicate that the addition of an ASGB causes significant weight loss in patients with poor weight loss outcome after RYGBP. The fact that no anastomosis or change in absorption is required may make this an attractive revisional strategy. Long- term evaluation in a larger population is warranted.
Although sestamibi scanning has been shown to have greater sensitivity and specificity than other preoperative localization techniques for parathyroid adenoma, it is unclear whether preoperative scanning improves outcomes for parathyroid surgery. Data from 528 consecutive patients who underwent neck exploration for primary hyperparathyroidism by one surgeon were collected prospectively over a 5-yr period. Patients were classified by preoperative scanning status (no scan, positive scan, and negative scan), and outcomes were compared in terms of operative time, length of hospital stay, and cure rate. Patients who had undergone a previous parathyroid operation and patients who received alternate preoperative localization techniques (ultrasound, magnetic resonance imaging, and computed tomography) were excluded from the study. All scans were ordered by the referring physician-the surgeon made no recommendations for preoperative scanning. All groups were similar in terms of gender, age, anesthesia class, body habitus, and complication rate. There was no significant difference in cure rate between patients who had preoperative scanning (97.5%) vs. those who did not (99.3%); however, there was a significant difference in cure rate between the negative-scan group (92.7%) and the positive and no-scan groups (99.3%, P < 0.01). In patients without concomitant thyroid surgery, there was no significant difference in operative time between the no scan (42.4 +/- 14.9 min) vs. the all-scan group (40.2 +/- 15.2 min); however, there was a significant difference between the negative scan group (44.5 +/- 21.9 min) and the positive scan group (38.5 +/- 12.6 min, P < 0.01). There was no significant difference in length of hospital stay among the three groups. These results suggest that, although preoperative sestamibi scanning does not alter the outcome of parathyroid surgery, it does identify those patients who are less likely to be cured.
Resection rate, margin status, and median survivals were equivalent when neoadjuvant patients were compared to patients considered resectable by traditional criteria, demonstrating equal efficacy. Surgical resection with venous reconstruction following neoadjuvant therapy for patients with locally advanced pancreatic cancer can be performed with acceptable morbidity and mortality. This approach extended the boundaries of surgical resection and greatly increased median survival for the "inoperable" patient with advanced pancreatic cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
