XXL-TYPE PERSONALITY. Personality traits promoting excess body weight.

THE AIM OF THE STUDY: The study aimed to determine whether persons suffering from obesity may be characterised by specific personality traits which promote the development of excess body weight. Additionally, the aim involved finding whether persons suffering from morbid obesity differed from healthy individuals and somatic patients as regards selected personality traits. MATERIAL AND METHODS: The study enrolled 34 patients with the diagnosis of morbid obesity in the process of qualification for surgical treatment of obesity. The patients' BMI ranged from 35 to 54 kg/m2. Study participants completed NEO-FFI personality inventory (Costa, McCare; 1998) and the authors' questionnaire designed to collect demographic data and anthropometric measurements. R esults: The study showed that patients with morbid obesity significantly differed from healthy individuals and somatic patients as regards the analysed measurements of the Big Five. C onclusions: The traits which were significantly distinctive in morbidly obese patients included lowered conscientiousness and increased neuroticism. The results indicate that the above pattern of personality traits may promote the development of excessive body weight.

Age is not associated with increased surgical complications in patients after laparoscopic sleeve gastrectomy.

INTRODUCTION: Age is considered as a risk factor in bariatric surgery. The observation was made on the basis of results from studies where patients underwent different type of surgery, but laparoscopic sleeve gastrectomy (LSG) was not among them. It is necessary to reevaluate the association of age with adverse events in the group of patients after LSG. AIM: To investigate the association of age with surgery-related adverse events in patients after LSG. MATERIAL AND METHODS: Retrospective analysis of medical data was performed. The study involved 345 patients who underwent LSG in our institution between January 2013 and December 2014. The patients were subdivided by age into four groups according to quartiles. In 30-day follow-up adverse events were evaluated. We considered the presence of the following events as the endpoint of our study: death, medical events and surgical events. RESULTS: In general, we observed adverse events in 36 (10.4%) patients. The mortality rate in our study was 0.59%. Nineteen events were surgical and 18 medical. In 1 patient a surgical event was associated with a medical event. Bleeding was the most common surgical event and was observed in 17 (4.9%) cases. Age was not associated with surgical events (OR = 1.032, 95% CI: 0.991-1.075, p = 0.33) or medical events (OR = 0.997, 95% CI: 0.956-1.039, p = 0.89). CONCLUSIONS: The LSG is a safe bariatric procedure with low mortality. Bleeding is the most frequent surgical complication. Our findings suggest that age is not associated with increased risk of surgical or medical adverse events after LSG.

Usefulness of the Obesity Surgery Mortality Risk Score (OR-MRS) in choosing the laparoscopic bariatric procedure.

INTRODUCTION: The most popular scale to stratify the postoperative risk is the Obesity Surgery Mortality Risk Score (OS-MRS). The design and ease of interpretation make the scale a potential tool for clinical use. AIM: To evaluate the usefulness of the OS-MRS scale in the enrollment of patients for laparoscopic bariatric procedures, including laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). MATERIAL AND METHODS: The medical records of patients who underwent LSG or LRYGB due to obesity between January 2010 and December 2010 were reviewed retrospectively. The decision of choosing the surgical procedure was made on the basis of OS-MRS risk category. The primary endpoint of this study was the 90-day mortality, and the secondary endpoint was the presence of major complications. RESULTS: There were 107 patients including 66 women and 41 men. The OS-MRS classes were A (48%), B (47%) and C (5%). The LSG was applied to patients with higher body mass index and to patients of class C. The secondary endpoints occurred in 6 patients, distributed in 10% of class A, 2% of class B and 0% of class C patients (p < 0.05). In 5 of 6 cases the endpoint was observed after LRYGB. Fatal cases were not observed. CONCLUSIONS: The OS-MRS can be a useful clinical tool for choosing the appropriate laparoscopic bariatric procedure, depending on the risk of postoperative complications. Low risk of postoperative complications should not lower the watchfulness of the surgeon.

Elastography in pancreatic solid tumours diagnoses.

INTRODUCTION: Pancreatic solid tumour diagnoses remain a challenge for modern medicine. However, using endosonography together with elastography helps to examine the elasticity of tissues and therefore may allow definition of the nature of pancreatic tumours. AIM: To evaluate the usefulness of elastography with the strain ratio method and quantitative evaluation of pancreatic solid tumours. MATERIAL AND METHODS: A total of 54 patients with pancreatic solid tumours were treated with ultrasound endosonography with fine-needle aspiration biopsy. The control group contained 26 patients with normal pancreas. Pancreatic solid tumours and normal pancreas were analysed with elastography and elasticity evaluation of the interest area (A), reference (B), and the strain ratio factor (B/A). Postoperative histopathological or cytological examinations were the final diagnoses. Both postoperative and cytological diagnoses were compared with average elasticity parameters (A) and strain ratio factors (B/A). RESULTS: Average elasticity parameters (A) and the strain ratio factors (B/A) were: 0.025% (0.01-0.05%) for malignant process, and (B/A) 33.93 (18.23-75.45); (A) - 0.26% (0.14-0.35%), and (B/A) 5.35 (3.47-7.8) for inflammatory process; (A) 0.54% (0.35-0.82%), and (B/A) 1.79 (1.02-2.05) for normal pancreatic tissue. CONCLUSIONS: Malignant tumours have higher tightness factor compared to inflammatory tumours and normal pancreatic tissue. Elasticity parameters reach the highest levels in normal pancreatic tissue, lower in inflammatory tumours, and the lowest in malignant tumours.
