How a broken vertebra can lead to a fatal hemorrhage: a case report.

BACKGROUND: Unintentional falls are common among the elderly and given the expected increase of the aging population, these falls contribute to a high number of admissions to the emergency department. Relatively low-energy trauma mechanisms can lead to serious injuries in the elderly, with contributing factors being comorbidities, medication use and degenerative abnormalities. CASE PRESENTATION: A 94-year-old female suffered an unintentional fall at home. Upon arrival of the ambulance at her house she was hemodynamically stable and mobilized to the gurney with assistance. During primary survey at the emergency department, her blood pressure and oxygen saturation decreased, she was not able to move her legs anymore and lost consciousness. A full-body CTA was performed, which showed a fracture through the vertebral body of L2 with significant dislocation and a large active bleeding of the corpus, extending to the retroperitoneum and the epidural space. Despite resuscitation, her vital signs deteriorated and given the severe abnormalities on CTA, it was decided to discontinue further treatment, after which she deceased. The performed CTA and an x-ray from 2016 suggested diffuse idiopathic skeletal hyperostosis, which might have contributed to the severity and instability of the vertebral fracture. Mobilization after the fall might have increased the dislocation of the fracture. The use of oral anticoagulants worsened the subsequent bleeding and the extension to the epidural space caused the paralysis of the legs. CONCLUSIONS: It is important to be aware of the possible serious consequences of unintentional falls in the elderly population and to provide strict immobilization of the spinal column until proper imaging.

Predictors for the occurrence of major complications after primary Roux-en-Y gastric bypass surgery.

BACKGROUND: The risk of developing postoperative complications after primary Roux-en-Y gastric bypass (RYGB) is relatively low. Nevertheless, postoperative complications can have serious consequences in terms of severe morbidity and health care costs. Identification of potential predictors is useful for further reduction of the postoperative complication rate. METHODS: This retrospective study included all patients undergoing primary RYGB between January 2010 and December 2013, using data from a prospectively collected database. Patients' characteristics, operative details and perioperative outcome were analyzed. RESULTS: A total of 773 patients (14.5% male) were included for analysis, with a mean age of 42.1±10.4 years and a mean Body Mass Index of 42.8±4.3 kg/m2. A total of 66 (8.5%) direct postoperative complications occurred. Clavien-Dindo grade 3a and higher occurred in 55 patients. Univariate analysis identified age (P=0.013), gender (P=0.017), BMI over 50 kg/m2 (P=0.096), hypertension (P=0.099), chronic obstructive pulmonary disease (P=0.002) and previous upper gastrointestinal surgery (P=0.095) as potential predictors. Multivariate logistic regression analysis showed that male gender (OR 2.412; 95%CI [1.212-4.797]) and chronic obstructive pulmonary disease (COPD) (OR 3.716; 95%CI [1.543-8.949]) were found to be independent predictors for the occurrence of major complications after primary RYGB. CONCLUSIONS: This study showed a number of potential predictors, of which male gender and COPD after multivariate regression analysis were found to be independent predictive factors for the occurrence of major complications after primary RYGB.

Long-term results after revisions of failed primary vertical banded gastroplasty.

AIM: To compare the results after revision of primary vertical banded gastroplasty (Re-VBG) and conversion to sleeve gastrectomy (cSG) or gastric bypass (cRYGB). METHODS: In this retrospective single-center study, all patients with a failed VBG who underwent revisional surgery were included. Medical charts were reviewed and additional postal questionnaires were sent to update follow-up. Weight loss, postoperative complications and long-term outcome were assessed. RESULTS: A total 152 patients were included in this study, of which 21 underwent Re-VBG, 16 underwent cSG and 115 patients underwent cRYGB. Sixteen patients necessitated a second revisional procedure. No patients were lost-to-follow-up. Two patients deceased during the follow-up period, 23 patients did not return the questionnaire. Main reasons for revision were dysphagia/vomiting, weight regain and insufficient weight loss. Excess weight loss (%EWL) after Re-VBG, cSG and cRYGB was, respectively, 45%, 57% and 72%. Eighteen patients (11.8%) reported postoperative complications and 27% reported long-term complaints. CONCLUSION: In terms of additional weight loss, postoperative complaints and reintervention rate, Roux-en-Y gastric bypass seems feasible as a revision for a failed VBG.

A Specifically Designed Stent for Anastomotic Leaks after Bariatric Surgery: Experiences in a Tertiary Referral Hospital.

BACKGROUND: The management of anastomotic leakage after either laparoscopic Roux-en-Y gastric bypass (LGBP) or laparoscopic sleeve gastrectomy (LSG) remains a burden. Various options are available for the treatment of these leaks. A newer and less invasive option for the treatment of leaks is the use of endoluminal stents. The main drawback for this treatment is stent migration. The current study describes the outcome of a new, specifically designed stent for the treatment of anastomotic leaks after bariatric surgery. METHODS: For this retrospective observational study, the medical charts of patients undergoing bariatric surgery between October 1, 2010 and July 1, 2013 were reviewed. All patients with anastomotic leakage, treated with the bariatric Hanarostent, were included. RESULTS: Twelve patients were included out of a total of 1702 bariatric patients in the described period. Seven had a leakage after LSG, five after LGBP. An average of 2.4 endoscopic procedures and 1.25 stents were used per patient. Successful treatment was seen in nine out of 12 patients (75 %). Most common complication was dislocation or migration of the stent, occurring in eight patients (66.7 %). CONCLUSIONS: The ECBB Hanarostent®, which was specifically designed for post bariatric leakages, shows equal but not favorable success rates in this small series compared to previous reports on other types of stenting techniques. Despite the stent design, the complication rate is not reduced and the main future goal should be to target the high stent migration rate.

Transection versus preservation of the neurovascular bundle of the lesser omentum in primary Roux-en-Y gastric bypass surgery.

BACKGROUND: A gastric pouch in Roux-en-Y gastric bypass (RYGB) surgery can be created after transection of the perigastric neurovascular bundle or by preserving these structures. Some surgeons choose to transect the neurovascular bundle (NBT), containing branches of the vagus nerve, because this might be related to additional weight loss, whereas others advocate preservation (NBP) to reduce postoperative complications. OBJECTIVES: This study assessed the effect of both techniques after primary RYGB. SETTING: All patients undergoing primary RYGB in a large bariatric center in the Netherlands between January 2010 and December 2013 were included. METHODS: Patient demographic characteristics, operative details, postoperative complications and weight loss after 1 year were retrospectively analyzed. RESULTS: A total of 773 consecutive patients were included (85.5% female). NBT was performed in 407 patients (52.7%), whereas NBP was performed in 366 patients. There were no missing data and 81.2% of patients completed the 1-year follow-up. Postoperative complications were found in 66 patients (8.5%). A total of 49 patients (6.3%) either had an anastomotic leakage, postoperative bleeding, or intraabdominal abscess (NBT 8.8% versus NBP 3.6%, P = .003). Percentage total weight loss (NBT 34.5%±6.9% versus NBP 33.4%±6.9%; P = .011) differed to a lesser extent between groups, although this was significant. Neurovascular bundle transection was identified as independent factor among others for occurrence of leakage, bleeding, and abscess development (OR 2.886; 95% CI [1.466-5.683]; P = .002). CONCLUSIONS: Transection of the neurovascular bundle in RYGB is associated with more complications. Furthermore, weight loss is not relevantly increased. Further research is necessitated to substantiate these findings.
