Predictors of psychological symptoms in morbidly obese patients after gastric bypass surgery
2012
Abstract Background Morbid obesity is associated with debilitating psychosocial consequences, such as depression, anxiety, and low self-esteem. One of the main goals of bariatric surgery should not only be reducing weight and counteracting co-morbid conditions, but also improving postoperative psychosocial functioning. The objective of our study was to determine the preoperative variables that could predict the psychological symptoms 6 and 12 months after surgery to improve the clinical outcome of morbidly obese patients undergoing bariatric surgery. The setting was a university hospital in Spain. Methods The study group consisted of 60 morbidly obese patients (46 women and 14 men) who had …
Checking the carotid pulse check: diagnostic accuracy of first responders in patients with and without a pulse.
1996
International guidelines for cardiopulmonary resuscitation (CPR) in adults advocate that cardiac arrest be recognized within 5-10 s, by the absence of a pulse in the carotid arteries. However, validation of first responders' assessment of the carotid pulse has begun only recently. We aimed (1) to develop a methodology to study diagnostic accuracy in detecting the presence or absence of the carotid pulse in unresponsive patients, and (2) to evaluate diagnostic accuracy and time required by first responders to assess the carotid pulse. In 16 patients undergoing coronary artery bypass grafting, four groups of first responders (EMT-1: 107 laypersons with basic life support (BLS) training; EMT-2…
Acute parathyroid hormone increase by oral peptones administration after roux-en-Y gastric bypass surgery in obese subjects: Role of phosphate in the…
2010
It is generally considered that changes in serum phosphate levels do not alter parathyroid hormone (PTH) secretion in the absence of concomitant changes in ionized serum calcium level in humans. An acute rise in PTH was shown after phosphate administration by intraduodenal gavage in rats. We aimed to study gastrin, phosphate, PTH, ionized calcium (iCa), and blood pH responses to oral peptones in morbidly obese patients before and after roux-en-Y gastric bypass (RYGB) surgery.These parameters were evaluated in response to an oral peptone load in 24 (18 male and 6 female) obese subjects before and 6 months after RYGB surgery. In 12 gastric bypass patients, we also evaluated PTH and phosphate …
Outcome of esophageal function and 24-hour esophageal pH monitoring after vertical banded gastroplasty and Roux-en-Y gastric bypass.
2004
Background: One of the co-morbidities frequently associated with morbid obesity is gastro-esophageal reflux disease (GERD), present in >50 % of morbidly obese individuals. We compared the anti-reflux effect of vertical banded gastroplasty (VBG) and Roux-en-Y gastric bypass (RYGBP), and their effect on esophageal function. Methods: 10 patients underwent VBG and 40 patients underwent RYGBP. Anthropometric parameters, symptomatology of GERD, esophageal manometry (EM), isotopic esophageal emptying (IEE) and 24hr esophageal pH monitoring were recorded in all patients preoperatively, and at 3 months and 1 year postoperatively. Results: Preoperatively, there was a high prevalence of GERD, symptoma…
Laparoscopic gastric banding as a universal method for the treatment of patients with morbid obesity.
2004
Introduction: This study analyzed the influence of potentially negative predictors such as sweet-eating behavior, super-obesity, social and psychological status, family and education situation, intake of sedative drugs, and the distance between hospital and home on the outcome of laparoscopic adjustable gastric banding (LAGB). Methods: 77 women and 29 men with mean age 40.6 years (28-47) underwent LAGB. Preoperative mean body weight was 146 kg (99-179), and mean BMI was 48.1 kg/m 2 (36.4-73.5). The influence of the above-mentioned potentially negative predictors on weight loss was the primary end point. Results: Mean follow-up was 44.6 ′ 19.7 months. Follow-up was possible in all but 6 pati…
Advantages of immediate two-dimensional echocardiography in patients with acute cardiac ischemic events
1995
Abstract We hypothesized that the assessment of kinetic alterations on two dimensional echocardiogram (2DE) would provide greater diagnostic information than clinical symptoms and ECG changes only. The study was aimed to determine sensitivity of 2DE in patients with cardiac ischemic events and to improve the indications to thrombolysis. Three-hundred ninety-one patients (87 F; 304 M) hospitalized for suspected acute myocardial infarction (AMI), first episode, within 4 h from the onset of symptoms, suitable for thrombolysis Killip class I–II and with unstable angina (UA), were admitted in the study. Patients had to show ECG changes and alterations of segmentary motion on 2DE performed at ent…
Short and long term results after intracoronary stenting in human coronary arteries: monocentre experience with the balloon-expandable Palmaz-Schatz …
1991
OBJECTIVE--Intracoronary stenting was designed to overcome acute complications after percutaneous transluminal coronary angioplasty and to achieve a reduced rate of restenosis, both of which are major limitations of this well accepted method for treating coronary heart disease. This report describes the experience at one centre with the implantation of balloon-expandable Palmaz-Schatz stents and focuses on device related complications and the short and long term angiographic outcome. DESIGN--A retrospective data analysis. PATIENTS--Stenting was attempted in 50 patients. Restenosis after an initially successful angioplasty procedure, inadequate postangioplasty results, saphenous coronary byp…
Impact of routine angiographic follow-up after angioplasty
1998
Abstract Background There is an ongoing controversy as to whether repeat coronary angiography should be routinely performed after successful percutaneous transluminal coronary angioplasty (PTCA). Methods We examined the 10-year outcome in 400 patients who had or had not undergone an angiographic control 6 months after successful PTCA and a subsequent event-free 6-month period. Our comparison was based on data gathered by questionnaire and telephone interview in 315 patients with (group A) and 85 patients without (group B) a routine 6-month angiographic control. Multivariate analysis (Cox model) was performed to identify predictors of adverse events. Results During the 10-year follow-up peri…
Vascular Grafts and Flow-through Flaps for Microsurgical Lower Extremity Reconstruction
2017
Background The use of vascular grafts is indicated in case of insufficient pedicle length or for complex defects involving both soft tissues and vessels. Venous grafts (for both venous and arterial reconstructions) and arterial grafts (arterial reconstruction) can be used. This study retrospectively evaluated the needs for vascular reconstruction and its results in a clinical series of lower limb reconstructions with microsurgical free flaps. Materials and Methods From 2010 to 2015, a total of 16 vascular grafts or flow-through flaps were used in 12 patients out of a total of 150 patients undergoing microsurgical reconstruction (8%). Arterial reconstruction was performed in seven cases (si…
Abdominal pain and internal hernias after Roux-en-Y Gastric Bypass: are we dealing with the tip of an iceberg?
2019
Background: Abdominal pain is the most frequent cause of hospital admission after Roux-en-y gastric bypass (RYGB). Among numerous possible underlying causes, internal hernias represent one of the most peculiar and insidious conditions, setting challenging diagnostic and therapeutic problems for the surgeon. The aim of this study is to analyze aspecific abdominal pain incidence and characteristics after RYGB, discriminating peculiar aspects suggestive of internal hernias. Methods: 13 patients submitted to internal hernia repair after laparoscopic antecolic RYGB and a group of 49 controls (non-complicated RYGB) have been assessed using a specific questionnaire. Overall aspecific abdominal pai…
