The relationship between plate prominence and need for removal after volar plate osteosynthesis of distal radius fractures.

PURPOSE: This study aimed to assess the incidence of plate-related complications and the need for plate removal after volar plate osteosynthesis of the distal radius in relation to Soong classification. METHODS: All consecutive patients (age > 16 years) in our level II trauma center treated with plate osteosynthesis for distal radius fractures from January 2017 until June 2019 were retrospectively evaluated. The main outcome measures were volar plate positioning according to Soong classification and incidence of plate removal. In addition, the incidence of tendon ruptures, reasons for volar plate removal, and improvement of complaints after removal were evaluated. RESULTS: The overall incidence of plate removal in the 336 included patients was 16.9% (n = 57). Removal incidence in Soong 2 plates (28.2%) was significantly higher compared to Soong 0 and 1 plates (8.0% and 14.4%, respectively), P = 0.003. Multivariable binary logistic regression analysis showed Soong grade 2 as an independent predictor for plate removal, OR 4.3 (95% CI 1.4-13.7, P = 0.013). Four cases of flexor and four cases of extensor tendon rupture were reported, all in Soong 2 grade plating. The main reasons for volar plate removal were pain (42%) and reduced functionality (12%). In cases where pain was the main reason for removal, 81% of patients reported a decrease in pain during follow-up after surgery. CONCLUSIONS: This study suggests an association between plate prominence graded by Soong and plate removal using a single plating system. Plate prominence should be reduced in volar plating whenever technically feasible.

First clinical results of 1-year follow-up of the femoral neck system for internal fixation of femoral neck fractures.

BACKGROUND: Closed reduction and internal fixation (CRIF) is the preferred treatment to retain the native joint and maintain optimal functionality in femoral neck fractures. Sliding hip screw (SHS) and cannulated hip screws (CHS) are established CRIF options. SHS offer high biomechanical stability, whereas CHS are minimally invasive. These established systems have a 17-21% failure rate. The Femoral neck system (FNS) was recently developed to combine the advantages of both predecessors. The aim of this study was to describe the first clinical experience with this novel implant with special emphasis on the safety and efficacy. METHODS: During a 1-year period all patients in our level-2 trauma centre with a FNF indicated for CRIF were treated using the FNS and evaluated at 2, 6, 12 weeks, 6 months and 1 year postoperatively using patient and fracture characteristics, surgical notes and radiographic imaging. RESULTS: Thirty-four patients were included, mean age was 63 years (SD 8), 58.2% was female. Fractures were classified as Pauwels I (n = 10), Pauwels II (n = 15), Pauwels III (n = 9), Garden I (n = 1), Garden II (n = 17), Garden III (n = 12) and Garden IV (n = 4). Eight reoperations were reported after 1-year follow-up; osteosyntheses failed in 6 patients due to avascular necrosis (n = 4) and cut-out (n = 2). In two patients the implant was removed due to inexplicable pain. Age (< 65 years) was related to lower risk for failure. There was a trend for females having more failures. CONCLUSION: This study indicates that the FNS is a potential safe and effective CRIF modality. Age (< 65 years) is an important factor to keep in mind when selecting patients for CRIF as it is related to lower risk for failure. Future long-term follow-up studies with larger populations should indicate if functional results and risk factors for failure are comparable to SHS or CHS.

Surgical treatment of acromioclavicular dislocation associated with midshaft fracture of the ipsilateral clavicle.

Acromioclavicular dislocation combined with a midshaft clavicle fracture is a rare traumatic shoulder problem. Various treatment options have been described in literature. We describe a new technique using a hook plate and coracoclavicular sling to replace the ruptured coracoclavicular ligaments in combination with plate osteosynthesis of the clavicle fracture. Furthermore, we provide a short overview of the few cases described in literature and their treatment options.

Fast Track Program in Conversion Bariatric Surgery, as Safe as in Primary Bariatric Surgery?

OBJECTIVES: Evaluate the safety of fast track (FT) surgery program in patients undergoing primary and revisional bariatric surgery (conversion from one procedure to another); identify limiting factors for early discharge and predictive factors for readmission. METHODS: This is a retrospective review of 730 consecutive morbidly obese patients who underwent bariatric surgery between January 2016 and December 2017. Fast track protocol was applied on all patients. Target discharge was after one-night stay. The primary end point is length of stay. The secondary end point is frequency of hospital contact after discharge, readmissions and reinterventions within 30 days. RESULTS: Primary procedures (n = 633) were banded Roux-en-Y gastric bypass (BRYGB, 79.3%), sleeve gastrectomy (10.7%), gastric band (4.7%) and others (5.3%). Mean age (± SD) was 44.32 ± 11.26 years, and mean BMI (± SD) was 43.58 ± 6.12 kg/m2. Conversion procedures (n = 97) were gastric band to BRYGB (40.2%), or to adjustable BRYGB (39.2%), Mason to BRYGB (11.3%), sleeve to BRYGB (4.1%) and others (5.2%). Mean age (± SD) was 47.22 ± 9.1 years, and mean BMI (± SD) was 37.9 ± 7.27 kg/m2. Mean LOS in primary patients was 1.3 ± 0.99, and that in conversion patients was 1.5 ± 1.4. Successful discharge at one night or less was achieved in 650 cases (573 primary and 77 conversion). After one-night discharge, incidence of contact to the hospital, readmission and reintervention was 23.9%, 5.9% and 1.9%, in the primary group and 31.2%, 13% and 5.2% in the conversion group. CONCLUSION: One-night discharge in FT managed conversion procedures is safe, compared to primary procedures. It is associated with higher readmission rates; however, the postdischarge hospital contacts and surgical complications were not statistically significant different.

Impact of Laparoscopic Banded Gastric Bypass on Weight Loss Surgery Outcomes: 5 Years' Experience.

OBJECTIVE: Evaluate 5-year outcomes of banded gastric bypass (BRYGB) as a primary and conversion bariatric procedure. METHODS: Retrospective review of BRYGB between January 2011and March 2013. Outcomes included percentage of total weight loss (%TWL), weight loss maintenance, and band-related complications. RESULTS: One hundred forty-two patients underwent BRYGB, 106 primary and 36 conversions. Indications for conversion to BRYGB were complications of the primary procedure (n = 19), insufficient weight loss (n = 5), and weight regain (n = 12). In the primary group, mean preoperative BMI was 44.8 kg/m2 (± 6.9 kg/m2). Compared with preoperative weight, mean %TWL was 33.9% (n = 95), 34.1% (n = 82), 34.0% (n = 70), 33.9% (n = 62), and 31.8% (n = 75) after 1, 2, 3, 4, and 5 years, respectively. In conversions secondary to failed primary procedure (insufficient WL and weight regain), mean preoperative BMI was 40.8 kg/m2 (± 6.01 kg/m2). Despite one patient gaining weight, mean %TWL was 25.7% (n = 13), 28% (n = 11), 23.9% (n = 8), 18.3% (n = 8), and 15.1% (n = 12) after 1, 2, 3, 4, and 5 years, respectively. In conversions secondary to primary procedure complications (n = 19), mean preoperative BMI was 28.4 kg/m2 (± 3.5 kg/m2). After 1, 2, 3, 4, and 5 years, mean BMI was 28.1 (n = 15), 29 (n = 10), 29.8 (n = 9), 30.6 (n = 10), and 30.9 (n = 12) kg/m2, respectively. Band-related complications after 5 years: three erosion and five patients complained of persistent dysphagia. One band needed reposition. Perioperative surgical complications: two bleeding, one leakage, one port-site hernia, and one food impaction. CONCLUSION: Banded gastric bypass has good results in terms of weight loss and weight loss maintenance in both primary and conversional bariatric procedures with acceptable incidence of band-related complications.

Conversion of Adjustable Gastric Banding to Adjustable Banded Roux-en-Y Gastric Bypass: Should We Leave the Band in Place?

OBJECTIVE: Laparoscopic adjustable gastric banding (LAGB) is rapidly becoming a deprecated bariatric procedure due to disappointing weight loss results and a high rate of band intolerance. Conversion to Roux-en-Y gastric bypass is a common revisional procedure after failed LAGB. The aim of this study was to evaluate the feasibility, safety, and risk profile of conversion to adjustable banded Roux-en-Y gastric bypass (ABRYGB). METHODS: A retrospective patient file review of all consecutive laparoscopic conversions of LAGB to ABRYGB 2008-2017. Pre/perioperative data, weight change, and long-/short-term complications were retrieved. RESULTS: Study population 98 patients. Mean BMI before revision was 40,15 kg/m2. Most revisional procedures were performed for band intolerance and/or weight regain or weight loss failure. All procedures were performed laparoscopically. During follow-up, 16 bands had to be removed due to one of the following reasons: infection, anastomotic leakage, anastomotic peptic perforation, adhesions around the anastomosis, internal hernia around the tubing, adhesions to the tubing, tubing failure, and erosion of the band. Three of those bands were replaced with a non-adjustable Silastic (Minimizer) ring. In total, issues with tubing requiring an intervention were found in 20 patients after conversion to ABRYGB. Seven revisional procedures had to be performed for symptomatic internal hernias not related to the tubing and incidental internal hernias were found in another 7 procedures. CONCLUSION: Although conversion of LAGB to ABRYGB is technically feasible, initially well-tolerated, and has good weight loss results, the number of additional procedures during follow-up is rather high, suggesting that leaving the band in place should not be advised.

The Gastric Band That Is Not to Be : Efficacy, Safety and Performance of the Easyband™: a Multicenter Experience.

BACKGROUND: Access port problems after laparoscopic adjustable gastric banding can be significant complications. The Easyband™ is an innovative type of gastric band, whose internal diameter can be adjusted by a telemetrically activated motor. The aim of this study was to evaluate safety, efficacy and performance of the Easyband™. METHODS: A total of 110 morbidly obese patients were prospectively enrolled. The Easyband™ was implanted laparoscopically by experienced bariatric surgeons in six different hospital locations. Patient characteristics, surgery details, postoperative weight loss, and complications were recorded. Follow-up lasted 2 years. RESULTS: Follow-up was completed by 78.2 % of the patients. Surgeons rated 71 % of each aspect of Easyband™ implantation as "easy" or "very easy". Adjustments were successful in 91 % of the attempts. One or more adverse events occurred in 79.1 % of the patients. Thirty-six serious adverse events were reported, of which 50 % was device-related. One or more functional tests failed in 20.9 % of the devices, 8.2 % passed after a repeated test. A reintervention was necessary in 15.5 % of the patients. Mean weight loss after 2 years was 24.2 ± 14.0 kg, mean excess weight loss was 46.1 ± 24 %. CONCLUSION: Excess weight loss with the Easyband™ was comparable with other gastric banding devices. Adjustment of the device was simple, non-invasive and more acceptable to patients than with a standard access port. However, a high incidence of device-related problems requiring surgical explantation occurred. The Easyband™ represents a major advance in gastric band design, but significant technical problems need to be resolved before further implants can be recommended.

Phenotypic fitness of primary endothelial cells cultured from patients with high cardiovascular risk or chronic kidney disease for vascular tissue engineering.

Vascular tissue engineering relies on the combination of patient-derived cells and biomaterials to create new vessels. For clinical application, data regarding the function and behavior of patient-derived cells are needed. We investigated cell growth and functional characteristics of human venous endothelial cells (HVECs) from coronary arterial bypass graft (CABG), chronic kidney disease (CKD), and control patients. HVECs were isolated from venous specimens that were obtained during elective surgical procedures by means of collagenase digestion. Gene expression, proliferation, migration, secretory functions, and thrombogenic characteristics were evaluated using high-throughput assays. A total of 48 cell batches (14 control, 19 CABG, and 15 CKD subjects) were assessed. Proliferation, population doubling times, and migration of HVECs derived from CABG and CKD patients did not differ from controls. Thrombomodulin expression was higher in CABG-HVECs compared with controls. HVEC-induced thrombin formation in plasma did not differ between groups, and the contact activation pathway was the major contributor to coagulation. Patient-derived HVECs were able to attach and survive on polycaprolactone scaffolds that were coated with fibrin. HVECs from cardiovascular-diseased and CKD patients showed comparable functional characteristics with HVECs derived from uncompromised patients. We, therefore, conclude that endothelial cells from aged patients with comorbidities can be safely used for isolation and in vitro expansion for vascular tissue engineering.

[A gastric pacemaker in obese type 2 diabetic patients]. / Een maagpacemaker bij patiënten met obesitas en diabetes mellitus type 2.

The combination of obesity and type 2 diabetes mellitus forms a growing global epidemic. The primary treatment for patients with this combination of conditions is to advise them to adopt a healthier lifestyle, but only a few patients succeed in doing this. Patients with type 2 diabetes who have to switch to insulin treatment can experience negative consequences, such as weight gain and an increased risk of hypoglycaemia. An alternative treatment that does not have these adverse effects is a gastric pacemaker, which can be implanted via laparoscopy: the patients lose weight and show an improvement in glucose regulation. The gastric pacemaker uses non-excitatory stimulation to influence the amplitude of gastric contraction. It simultaneously stimulates afferent fibres of the vagal nerve to influence the cerebral satiation centre, which is involved in registration of satiety and in insulin secretion and resistance. A randomized trial on the effects of the gastric pacemaker in patients with obesity and type 2 diabetes mellitus is currently being conducted in the Atrium Medical Centre in Heerlen.

Roux-en-Y gastric bypass as revisional procedure after gastric banding: leaving the band in place.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB) are frequently used bariatric procedures. With both techniques, LAGB more than RYGB, failures occur. After years of experience with both techniques, we present a series of patients who underwent RYGB after failed LAGB. The band was kept in place. Our objective was to evaluate the safety and short-term effectiveness of RYGB after failed LAGB, without removing the band. The setting was a large teaching hospital in Heerlen, The Netherlands. METHODS: We first retrospectively considered the efficacy and complication rate of adding an adjustable band to RYGB. This was safe and effective. The patients lost a median of 7.6 kg within a median period of 21 months. The complication rate was low. Observing the positive results in this group, we began to leave the band in place when converting patients from LAGB to RYGB. RESULTS: A total of 12 patients underwent revision of LAGB to RYGB. There was no mortality. The complication rate and severity were low. During a median period of 16 months, the patients lost a median of 23 kg or 8 points in the body mass index. Also, additional improvement in co-morbidities was observed. CONCLUSION: Our results suggest that performing RYGB after LAGB and leaving the band in place is feasible, safe, and effective in the short term.

Integrated nutritional intervention in the elderly after hip fracture. A process evaluation.

BACKGROUND & AIMS: Within a multicentre randomized controlled trial aimed at improving the nutritional status and increase the speed of recovery of elderly hip fracture patients, we performed a process evaluation to investigate the feasibility of the intervention within the present Dutch health care system. METHODS: Patients in the intervention group received nutritional counseling during 10 contacts. Oral nutritional supplements were advised as needed until three months after hip fracture surgery. The intervention was evaluated with respect to dieticians' adherence to the study protocol, content of nutritional counseling, and patients' adherence to recommendations given. RESULTS: We included 66 patients (mean age of 76, range 55-92 years); 74% women. Eighty-three percent of patients received all 10 contacts as planned, but in 62% of the patients one or more telephone calls had to be replaced by face to face contacts. Nutritional counseling was complete in 91% of contacts. Oral nutritional supplementation was needed for a median period of 76 days; 75% of the patients took the oral nutritional supplements as recommended. CONCLUSIONS: Nutritional counseling in elderly hip fracture patients through face to face contacts and telephone calls is feasible. However, individual tailoring of the intervention is recommended. The majority of hip fracture patients needed >2 months oral nutritional supplements to meet their nutritional requirements. The trial was registered at clincialtrails.gov as NCT00523575.

Efficacy and cost-effectiveness of nutritional intervention in elderly after hip fracture: design of a randomized controlled trial.

BACKGROUND: Hip fracture patients often have an impaired nutritional status at the time of fracture, which can result in a higher complication rate, prolonged rehabilitation time and increased mortality. A study was designed to evaluate the effect of nutritional intervention on nutritional status, functional status, total length of stay, postoperative complications and cost-effectiveness. METHODS: Open-labelled, multi-centre, randomized controlled trial in hip fracture patients aged 55 years and above. The intervention group receives dietetic counselling (by regular home visits and telephone calls) and oral nutritional supplementation for three months after surgery. The control group receives usual dietetic care as provided by the hospital. Outcome assessment is performed at three and six months after hip fracture. DISCUSSION: Patient recruitment has started in July 2007 and has ended in December 2009. First results are expected in 2011. TRIAL REGISTRATION: ClinicalTrials.gov NCT00523575.
