Massive necrotizing fasciitis : a life threatening entity

Altres ajuts: The authors want to thank the Dr. Vilallonga Foundation for the financial support in the preparation of this article (http://www.fundacioramonvilallonga.org).Necrotizing fasciitis (NF) is a complicated soft tissue infection frequently associated with severe sepsis if an early medical and surgical treatment is not performed. We report two postoperative cases of severe NF after oophorectomy and colorectal resection. Because of the similarity with more benign skin infections at the early steps, clinical suspicion is crucial. Surgical exploration and resection will provide both the diagnosis confirming necrotizing infection of the fascia with vessels and treatment. Also, empirical broad-spectrum antibiotics must be initiated as soon as possible. Regardless of the presence of risk factors, NF is a condition with a high mortality rate and only an expeditious and undelayed treatment may improve the patient's outcome. Surgical focus control requires wide and repeated resections, and planned reconstructive plastic surgery might be necessary

Evolution of Differentiated Thyroid Cancer : A Decade of Thyroidectomies in a Single Institution

Numerous studies have shown an increase in the incidence of thyroid cancer (TC) in recent years. In this paper, we reviewed the incidence of TC in a series of patients undergoing thyroid surgery at a single institution over a 10-year period. The cohorts were divided into two periods (2001-2005 and 2006-2010) with the purpose of comparing various clinicopathologic variables. A total of 1,263 patients were included. A significant increase in the number of malignancies was shown in the second period, namely 90 cases in 2001-2005 (15.2% of all interventions) compared to 163 cases in 2006-2010 (24.3%) (p < 0.001). These differences were attributed to an increase in papillary thyroid carcinoma (PTC), as there were 66 PTC cases in the first period (11.13% of thyroidectomies performed) compared to 129 cases in the second period (19.25%). There were no clinicohistological differences among PTC cases in these two periods. Over the last decade, there has been an increase in the incidence of TC in patients undergoing thyroid surgery. This increase is exclusively due to increases in PTC. Our study verifies the existence of this trend in our geographical area, similar to that noted in other parts of the world

Brown tumor of the jaw after pregnancy and lactation in a MEN1 patient

Skeletal manifestations of primary hyperparathyroidism (pHPT) include brown tumors (BT), which are osteoclastic focal lesions often localized in the jaws. Brown tumors are a rare manifestation of pHTP in Europe and USA; however, they are frequent in developing countries, probably related to vitamin D deficiency and longer duration and severity of disease. In the majority of cases, the removal of the parathyroid adenoma is enough for the bone to remineralize, but other cases require surgery. Hyperparathyroidism in MEN1 develops early, and is multiglandular and the timing of surgery remains questionable. To our knowledge, there are no reports of BT in MEN 1 patients. We present a 29-year-old woman with MEN 1 who developed a brown tumor of the jaw 24 months after getting pregnant, while breastfeeding. Serum corrected calcium remained under 2.7 during gestation, and at that point reached a maximum of 2.82 mmol/L. Concomitant PTH was 196 pg/mL, vitamin D 13.7 ng/mL and alkaline phosphatase 150 IU/L. Bone mineral density showed osteopenia on spine and femoral neck (both T-scores = −1.6). Total parathyroidectomy was performed within two weeks, with a failed glandular graft autotransplantation, leading to permanent hypoparathyroidism. Two months after removal of parathyroid glands, the jaw tumor did not shrink; thus, finally it was successfully excised. We hypothesize that higher vitamin D and mineral requirements during maternity may have triggered an accelerated bone resorption followed by appearance of the jaw BT. We suggest to treat pHPT before planning a pregnancy in MEN1 women or otherwise supplement with vitamin D, although this approach may precipitate severe hypercalcemia

Diabetic and dyslipidaemic morbidly obese exhibit more liver alterations compared with healthy morbidly obese

Background & aims: To study the origin of fat excess in the livers of morbidly obese (MO) individuals, we analysed lipids and lipases in both plasma and liver and genes involved in lipid transport, or related with, in that organ. Methods: Thirty-two MO patients were grouped according to the absence (healthy: DM−DL−) or presence of comorbidities (dyslipidemic: DM−DL+; or dyslipidemic with type 2 diabetes: DM+DL+) before and one year after gastric bypass. Results: The livers of healthy, DL and DM patients contained more lipids (9.8, 9.5 and 13.7 times, respectively) than those of control subjects. The genes implicated in liver lipid uptake, including HL, LPL, VLDLr, and FAT/CD36, showed increased expression compared with the controls. The expression of genes involved in lipid-related processes outside of the liver, such as apoB, PPARα and PGC1α, CYP7a1 and HMGCR, was reduced in these patients compared with the controls. PAI1 and TNFα gene expression in the diabetic livers was increased compared with the other obese groups and control group. Increased steatosis and fibrosis were also noted in the MO individuals. Conclusions: Hepatic lipid parameters in MO patients change based on their comorbidities. The gene expression and lipid levels after bariatric surgery were less prominent in the diabetic patients. Lipid receptor overexpression could enable the liver to capture circulating lipids, thus favouring the steatosis typically observed in diabetic and dyslipidaemic MO individuals.This research has received funding from the Fondo de Investigación Sanitaria del Instituto de Salud Carlos III of the Spanish Ministry for Health and Consumer Affairs (PI030024, PI030042, PI070079 and PI11/01159

The Initial Learning Curve for Robot-Assisted Sleeve Gastrectomy: A Surgeon’s Experience While Introducing the Robotic Technology in a Bariatric Surgery Department

Objective. Robot-assisted sleeve gastrectomy has the potential to treat patients with obesity and its comorbidities. To evaluate the learning curve for this procedure before undergoing Roux en-Y gastric bypass is the objective of this paper. Materials and Methods. Robot-assisted sleeve gastrectomy was attempted in 32 consecutive patients. A survey was performed in order to identify performance variables during completion of the learning curve. Total operative time (OT), docking time (DT), complications, and length of hospital stay were compared among patients divided into two cohorts according to the surgical experience. Scattergrams and continuous curves were plotted to develop a robotic sleeve gastrectomy learning curve. Results. Overall OT time decreased from 89.8 minutes in cohort 1 to 70.1 minutes in cohort 2, with less than 5% change in OT after case 19. Time from incision to docking decreased from 9.5 minutes in cohort 1 to 7.6 minutes in cohort 2. The time required to dock the robotic system also decreased. The complication rate was the same in the two cohorts. Conclusion. Our survey indicates that technique and outcomes for robot-assisted sleeve gastrectomy gradually improve with experience. We found that the learning curve for performing a sleeve gastrectomy using the da Vinci system is completed after about 20 cases

Robotically Assisted Single Anastomosis Duodenoileal Bypass after Previous Sleeve Gastrectomy Implementing High Valuable Technology for Complex Procedures

Staged bariatric procedures in high risk patients are a common used strategy for morbid obese patients nowadays. After previous sleeve gastrectomy, surgical treatments in order to complete weight loss or comorbidities improvements or resolutions are possible. One strategy is to perform a novel technique named SADI (single anastomosis duodenoileal bypass-sleeve). We present the technique for totally intracorporeal robotically assisted SADI using five ports and a liver retractor. We aim to see if the robotic technology offers more advantageous anastomosis and dissection obtained by the robotic approach in comparison to standard laparoscopy. The safety, feasibility, and reproducibility of a minimally invasive robotic surgical approach to complex abdominal operations such as SADI are discussed

Iodine deficiency is higher in morbid obesity in comparison with late after bariatric surgery and non-obese women

Background Iodine deficiency and obesity are worldwideoccurring health problems. Our purpose was to investigate the relationship between morbid obesity and iodine status, including subjects who lost weight after bariatric surgery. Methods Ninety morbidly obese women, 90 women with at least 18 months follow-up after bariatric surgery, and 45 healthy non-obese women were recruited. Urinary iodine concentration (UIC) was measured in a spot urinary sample and expressed as the iodine-to-creatinine ratio. Results Obese women showed a significantly lower UIC in comparison with non-obese women (96.6 (25.8–267.3) vs. 173.3 (47.0–493.6) μg/g; p<0.001), with a lesser proportion of subjects with adequate iodine status (46.6 vs. 83.3 %, p<0.001). The mean UIC significantly increased among women who underwent bariatric surgery before the collection of the urinary sample (96.6 (25.8–267.3) vs. 131.9 (62.9– 496.4) μg/g; p<0.001). No difference in UIC was detected between laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy. Univariate analysis showed that UIC negatively correlated with body mass index (BMI) (r=−0.278, p<0.001) and positively with age (r=0.206, p=0.002). Finally, multiple linear regression analyses showed that BMI was independently associated with UIC (beta=−0.312, p<0.001; R2=0.166). Conclusion Obesity is an independent risk factor to iodine deficiency, almost in women.Whether more obese population needs to be considered as a vulnerable group and whether bariatric surgery can reverse iodine deficiency still remain to be elucidated
