Bariatric surgery in elderly patients. A comparison between gastric banding and sleeve gastrectomy with five years of follow up
No full textIntroduction: The prevalence of obesity is rising progressively, even among elderly patients. Many studies investigated about safety and efficacy of bariatric surgery among aged obese patients. The objective of this review is to assess the benefits relative to risks of weight loss that may be obtained by performing two common bariatric procedures in obese elderly patient. Materials and methods: We retrospectively evaluated 10 morbid obese patients older than 60 years reaching 5 years of follow up who respectively underwent Laparoscopic Sleeve Gastrectomy (LSG) or Laparoscopic Adjustable Gastric Banding (LAGB). Eventual changes in comorbidities, weight loss, EWL% were investigated. Results: Although LSG patients required a longer postoperative hospital stay than LAGB patients (p < 0.001), both procedures have shown to be safe and equally effective for weight loss achievement in elderly patients. Whereas all patients showed comorbidities resolution, no significant difference in weight loss between LAGB group and LSG group was found at 1 year (EWL% p = 0.87; BMI p = 0.32), 3 years (EWL% p = 0.62; BMI p = 0.79) and 5 years (EWL% p = 0.52; BMI p = 0.46) of follow up. Conclusions: Bariatric surgery is safe and effective to reach obesity related comorbidities resolution among elderly obese patients. Both LAGB and LSG determine a weight loss lesser than observed in a standard bariatric population. In this study LSG is significantly less cost effective than LAGB. Larger studies with longer follow up are however needed to evaluate the real impact of bariatric surgery on weight loss, resolution of comorbidities and improvement of quality of life in elderly obese patients
Retrieval of the gastric specimen following laparoscopic sleeve gastrectomy. Experience on 275 cases
No full textSevere obesity leads to a high incidence of complications and a decrease in life expectancy, especially among younger adults. Laparoscopic sleeve gastrectomy (LSG) first intended as the first step of biliopancreatic diversion with duodenal switch is gaining a per-se procedure role because of its effectiveness on weight loss and comorbidity resolution. Different techniques have been described for specimen extraction in LSG. In this article we report the technique adopted in 275 LSGs performed in our department. In the first 120 LSGs performed from 2007, the specimen was extracted through a mini laparotomy. In the following 155 cases the technique has been simplified: the grasped specimen has been withdrawn through the 15 mm trocar site. We registered in the fist group six cases of wound infection (5%), ten cases of hematoma (8.3%) and four cases of port site hernia (3.3%). In the second group only one case of hematoma (0.6%, p = 0.01) but no cases of wound infection (p = 0.01) or port site hernia, (p = 0.03) although we registered a specimen perforation during retrieval in 16 patients, were reported. The technique described in the 155 cases of the control group has shown to be more effective than the technique we used in the case group, allowing significantly lower operative time (112.9 ± 1.0 vs 74.9 ± 9.1 p < 0.001) and complications, and providing unchanged costs
Pilonidal sinus surgery: Could we predict postoperative complications?
No full textPilonidal sinus surgery could, as of now, be considered a surgery tailored more to the surgeon than to the patient. In an attempt to give to surgeons an objective instrument of decision, we have evaluated which variables could be considered predictive of postoperative complications after pilonidal sinus surgery. A prospective electronic database of all patients treated for sacrococcygeal pilonidal disease was analysed. Sex, age, obesity, smoking, recurrent disease, the presence of multiple orifices and the distance between the most lateral orifice and midline were recorded and correlated with the occurrence of postoperative complications (infection and recurrence); 1006 patients were evaluated. Excision with primary mid-line closure was performed on all the patients. Mean follow-up was 7·3±3·6years. A total of 158 patients with postoperative complications (infection and/or recurrence) were recorded during this period. A multivariate analysis showed that, after adjusting for major clinical and demographic characteristics, only a recurrent disease [odds ratio (OR): 3·41, 95% confidence interval (CI): 1·89-6·15, P<0·001] and the distance of lateral orifice from midline (OR: 26·3, 95% CI: 12·2-56·7, P<0·001) were independent predictors of overall postoperative complications. Focussing on the distance from midline, the receiver operative characteristic (ROC) analysis showed that the distance of lateral orifice from midline predicted 79·2% of complications and the Youden's test identified the best cut-off as 2·0cm for this variable. An evidence-based tool for deciding on the type of surgical intervention could be developed and validated by further ad hoc prospective studies evaluating our results in comparison to other different types of surgical techniques. Our results support the use of these variables as an effective way to tailor pilonidal sinus surgery to the patient, so as to obtain the best results in patient care
Gut Microbiota Features in Young Children with Autism Spectrum Disorders. [*Coretti L. corresponding author]
No full textProliferation and/or depletion of clusters of specific bacteria regulate intestinal functions and may interfere with neuro-immune communication and behavior in patients with autism spectrum disorder (ASD). Consistently, qualitative and quantitative alteration of bacterial metabolites may functionally affect ASD pathophysiology. Up to date, age-restricted cohort studies, that may potentially help to identify specific microbial signatures in ASD, are lacking. We investigated the gut microbiota (GM) structure and fecal short chain fatty acids (SCFAs) levels in a cohort of young children (2-4 years of age) with ASD, with respect to age-matched neurotypical healthy controls. Strong increase of Bacteroidetes and Proteobacteria and decrease of Actinobacteria was observed in these patients. Among the 91 OTUs whose relative abundance was altered in ASD patients, we observed a striking depletion of Bifidobacterium longum, one of the dominant bacteria in infant GM and, conversely, an increase of Faecalibacterium prausnitzii, a late colonizer of healthy human gut and a major butyrate producer. High levels of F. prausnitzii were associated to increase of fecal butyrate levels within normal range, and over representation of KEGG functions related to butyrate production in ASD patients. Here we report unbalance of GM structure with a shift in colonization by gut beneficial bacterial species in ASD patients as off early childhood
Thyroidectomy in high body mass index patients: A single center experience
No full textAbstract
BACKGROUND:
To identify the correlation between high body mass index (BMI ≥ 25) and the risk of postoperative complications of thyroidectomy.
METHODS:
A comparative study between thyroidectomy performed in normal or overweigh-obese patients has been performed. Postoperative outcomes, including hypocalcemia, laryngeal nerve palsy, bleeding, operation time and hospital stay, were evaluated.
RESULTS:
A total of 266 patients underwent total thyroidectomy were included. Of them, 104 patients had a BMI below 25 and 162 patients had a BMI ≥ 25. There was no statistically significant difference in the occurrence of early or permanent hypoparathyroidism, recurrent laryngeal nerve palsy, bleeding complications, or postoperative duration of hospital stay. There was, however, a higher operative time in patients with a BMI ≥ 25.
CONCLUSION:
Despite the longer operative time, thyroidectomy can be performed safely in patients with a BMI ≥ 25
Does regional belonging explain the similarities in the expenditure determinants of Italian healthcare deliveries? An approach based on Artificial Neural Networks
No full textThe investigation of the determinants of public health expenditure is the focus of a vivid debate among health economists whereas the actual crisis of the welfare systems calls for the adoption of innovative tools to inform rational decisions, in the light of stringent budget constraints. The purpose of this paper is to show the potentialities of Artificial Neural Networks (ANNs) in investigating whether healthcare providers belonging to the same jurisdiction show similarities in their health care expenditure determinants. Similarities are reproduced in terms of fuzzy dependencies between health budgetary data of the healthcare providers belonging to five Italian regions. The analysis carried out sees the application of Auto Contractive Maps (AutoCM) model. The methodology is effective in illustrating regional patterns of expenditure and similarities across Local Health Units (Aziende Sanitarie Locali—ASLs). The results give interesting insights on the presence of notable regional models for health expenditure. © 2017 Economic Society of Australia, Queenslan
