RESUMEN
PURPOSE: To establish the prevalence and risk factors for intravitreal dexamethasone implant migration into the anterior chamber in eyes with macular edema. METHODS: This was a multicenter, retrospective, observational chart review of data that included patients with macular edema who had been treated with at least one intravitreal dexamethasone injection. Patients with incomplete chart information during the follow-up period were excluded. RESULTS: The prevalence of implant migration in 468 patients, considering the number of injections, was 1.6%, with significant associations between implant migration and cataract surgery (P = 0.043) and intraocular lens status (P = 0.005) and a trend toward statistical significance (P = 0.057) with vitrectomy. A higher rate of implant migration into the anterior chamber was observed in vitrectomized eyes (4.8%) when compared with patients who did not undergo a vitrectomy (1.6%). The implants that migrated were removed with forceps with/without viscoelastic expression or with 20-gauge cannulas connected to the vitreous cutter machine. CONCLUSION: The risk of implant migration into the anterior chamber was 1.6%. Risk factors were a history of cataract surgery or vitrectomy and aphakia. When anterior migration occurs, rapid removal is advised, especially if corneal edema is present.

Abstract Objective: Anticoagulation is the primary management to prevent venous thromboembolism; inferior vena cava filters (IVCFs) provide a mechanical prophylactic alternative when anticoagulation is contraindicated. The aim of this study was to evaluate in IVCF patients, whether the initiation of anticoagulation therapy is associated with decreased rates of recurrent thrombotic events and device-related complications. Methods: This was a retrospective review of patients that underwent insertion of IVCF. Subjects with IVCF were studied in two groups: those initiated on anticoagulation (A) and without anticoagulation (NA). Variables as indications for IVCF, anticoagulation, recurrence of thrombosis, complications, and reinterventions were examined. Results: From April 2007 to March 2014, 54 patients underwent IVCF placement; (61% of females), with mean age of 54 years (standard deviation ± 19). 28 (52%) were initiated on anticoagulation, during a mean follow-up period of 28 months, five experienced recurrent thrombosis and three were on the A group (p=0.5); when comparing patients that developed post-thrombotic syndrome, seven were in the A group and seven in the NA. Two patients with IVC rupture were in the A group (p=0.5), and the only case of IVCF migration occurred in the A group. 11 (20%) patients died from comorbidities nonrelated to the device or procedure (four in the A cohort). Conclusions: Patients with IVCF on anticoagulation have equivalent rates of thrombotic events and device-related complications than those patients NA.
Resumen Objetivo: La anticoagulación es la terapia de elección para la prevención de tromboembolismo venoso; los filtros de vena cava inferior (FVCI) proveen una alternativa mecánica profiláctica cuando la anticoagulación está contraindicada. El objetivo de este estudio fue evaluar si la terapia anticoagulante se asocia con una tasa menor de eventos trombóticos recurrentes y complicaciones relacionadas con el dispositivo. Métodos: Los pacientes fueron categorizados en dos grupos: Aquellos a los que se les inicio anticoagulación (A) y aquellos que no (NA). Variables tales como indicación de la colocación del filtro, anticoagulación, recurrencia de trombosis y complicaciones fueron examinadas. Resultados: De abril de 2007 a marzo 2014, a 54 pacientes se les coloco un filtro (61% fueron mujeres), con una media de edad de 54 años [Desviación estándar (DE) ±19. Veintiocho (52%) fueron iniciados en anticoagulación y durante un seguimiento de 28 meses, 5 pacientes experimentaron recurrencia de trombosis, 3 en el grupo A (p=0.5). Al comparar los pacientes que desarrollaron síndrome posflebítico, 7 pertenecieron al grupo A y 7 al grupo NA. Dos pacientes con ruptura de vena cava pertenecieron al grupo A (p=0.5) y el único caso de migración del dispositivo ocurrió en el grupo A. Once (20%) pacientes fallecieron debido a comorbilidades no relacionadas con el dispositivo o el procedimiento. Conclusión: Pacientes con FVCI en anticoagulación tienen tasas de eventos trombóticos y complicaciones asociadas a los dispositivos equivalentes a aquellos pacientes sin anticoagulación.

PURPOSE OF REVIEW: The present manuscript reviews the mechanism of action of drug-coated balloons (DCBs), offering a brief summary of the main clinical evidence on these devices. RECENT FINDINGS: DCBs are regular semi-compliant balloons coated with antiproliferative agents that are rapidly released on contact with the vessel intima, exerting an anti-restenotic effect. This technology may offer some benefits of drug-eluting stents, in particular for the treatment of restenotic lesions, small vessels, and in patients at high-bleeding risk, when the prolonged dual antiplatelet regimen should be avoided. Most recent data have pointed to a possible benefit of these devices in treating bare metal stents (BMS) or drug-eluting stents in-stent restenosis (DES ISR), effectively reducing the recurrence of restenosis and avoiding additional layers of metal in the same coronary segment. In other clinical scenarios such as bifurcations, small vessels, and de novo lesions, data is more scarce and the benefits are still unclear. There are potential benefits related to the use of DCB in selected populations. However, larger clinical trials with longer follow-up are still needed to confirm the enthusiastic initial results.

This article identifies, quantifies and categorizes adverse event notifications and technical complaints related to the use of vascular catheters, received by the Notivisa system in the period from January 2007 to June 2016. It is a descriptive, retrospective, documental study with a quantitative approach. Data requested and supplied by Anvisa were analyzed and presented in the form of charts and tables. The study covered 4,682 notifications of technical complaints, and 671 adverse events. There was a progressive increase in notifications during the period studied. As to the type of technical complaint, the majority referred to 'suspected quality failings', the largest component being due to 'catheter rupture during procedure'. The adverse event most notified was 'catheter broke in the vein and migrated to another part of the body'. In the period studied there were four notifications of deaths, the most severe level of adverse event. The study made it possible to visualize the importance of after-sales surveillance of vascular catheters, as well as supplying a wide-ranging overview of their use. Provision of this overview could support technical surveillance activities and serve as input for public policies relating to this product.

BACKGROUND: Infection is the most common complication related to permanent pacemaker implantation. The objetive of this study is to establish the prevalence and determine the frequency of risk factors associated with exteriorization of cardiac pacemakers at the Department of Cardiac Electrophysiology at the UMAE Hospital de Especialidades "Dr. Antonio Fraga Mouret" Centro Médico Nacional La Raza, Instituto Mexicano del Seguro Social. METHODS: A descriptive cross-sectional study from September 2005 to September 2010, where, for the analysis of the risk factors we selected cases and controls by age, sex and the diagnosis of Diabetes, or not. Was calculated measures of central tendency (mean, median and mode) and chi-squared, Fisher exact test and exact odds ratio. RESULTS: 3192 cardiac pacemakers were implanted, identifying 83 exteriorization cases, where 46 of them were selected for cases and controls, and the mean age was 71 years. CONCLUSIONS: Our prevalence of exteriorization of cardiac pacemakers is 2.6 %, these results are similar to previously published studies. None of the risk factors described are present as a cause in our population. The surgical technique used may be an important risk factor, so further studies analysing all techniques are needed.

RACIONAL: A doença do refluxo gastroesofágico é uma das enfermidades do trato gastrointestinal mais frequentes atualmente. A fundoplicatura de Nissen-Rossetti é técnica operatória muito empregada para o tratamento cirúrgico, sendo a migração intratorácica da válvula uma das principais complicações. OBJETIVO: Avaliar a incidência da migração da fundoplicatura e seus fatores de risco. MÉTODO: Analisou-se retrospectivamente 207 prontuários de pacientes submetidos à fundoplicatura videolaparoscópica pela técnica de Nissen-Rossetti para tratamento da doença do refluxo. As variáveis analisadas foram: sexo, idade, esofagite, grau de esofagite, tamanho da hérnia, alargamento da cárdia, encurtamento esofágico. Para as variáveis quantitativas, foi considerado o teste t de Student. Para as nominais, foi considerado o teste de Qui-quadrado ou o teste exato de Fisher. Valores de p<0,05 indicaram significância estatística. RESULTADOS: Do total, 135 eram mulheres (65,22%) e 72 homens (34,78%), com média de idade de 47,43 anos. O tamanho da hérnia variou entre 2 e 6 cm. Duzentos pacientes tinham esofagite (96,62%), sendo 113 (56,50%) grau I, 75 grau II (37,50%) e 12 grau III ou IV (6%). Alargamento de cárdia e esôfago de Barrett foram vistos em 153 (73,91%) e 13 (6,28%) casos, respectivamente. Um paciente apresentava encurtamento esofágico. Dentre as mulheres, 33 (24,4%) apresentaram migração e entre os homens, apenas seis (8,3%) (p = 0,005). A idade média dos pacientes com e sem migração foi de 54,03 e 45,89 anos, respectivamente (p = 0,001). CONCLUSÃO: A incidência da migração da fundoplicatura foi de 18,8%. O gênero feminino e possuir maior idade influenciam na probabilidade dessa migração. O grau de esofagite, tamanho da hérnia e alargamento da cárdia não se mostraram fatores de risco para migração intratorácica da fundoplicatura.
BACKGROUND: Gastroesophageal reflux is the gastrointestinal tract disease most frequently find nowadays. The Nissen-Rossetti fundoplication is widely used for the surgical treatment, and intrathoracic migration of the valve is the most frequent complication. AIM: To assess the incidence of the fundoplication and its risk factors. METHODS: Were analyzed retrospectively medical records of 207 patients undergoing laparoscopic fundoplication by the Nissen-Rossetti technique for the treatment of reflux disease. The variables analyzed were: sex, age, esophagitis grade, size of the herniation, enlargement of the cardia and esophageal shortening. For quantitative variables, was considered the Student's t test. For the nominal, was considered the chi-square or Fisher's exact test. P values <0.05 were considered statistically significant. RESULTS: Of the total, 135 were women (65.22%) and 72 men (34.78%) with mean age of 47.43 years. The size of the hernia varied between 2 and 6 cm. Two hundred patients had esophagitis (96.62%) and 113 (56.50%) grade I, 75 grade II (37.50%) and 12 grade III or IV (6%). Enlargement of the cardia and Barrett's esophagus were seen in 153 (73.91%) and 13 (6.28%) cases, respectively. One patient had esophageal shortening. Among women, 33 (24.4%) showed migration and among men, only six (8.3%) (p = 0.005). The average age of patients with and without migration was 54.03 and 45.89 years, respectively (p = 0.001). CONCLUSION: The incidence of the fundoplication migration was 18.8%. The gender (female) and higher age influence the probability of migration. The degree of esophagitis, size of hernia and enlargement of the cardia were not risk factors for intrathoracic migration of the fundoplication.

INTRODUCTION: Catheter-related complications in patients on peritoneal dialysis lead to decreased effectiveness and discontinuation of the technique, conversion to haemodialysis, hospitalisation, and surgical interventions to replace the catheter. OBJECTIVES: Determine risk factors for early catheter dysfunction that result in the need for replacement. METHODS: We analysed 235 catheters placed by open surgery using an infra-umbilical midline incision. Possible risk factors included the following: age, sex, body mass index, body surface area, diabetes, polycystic kidney disease, previous surgery, time of surgical procedure, omentectomy, omentopexy, wound infection and postoperative incisional hernia. RESULTS: During the first year, 47 patients (20%) required a catheter replacement due to poor function. The most common complications were catheter migration and peritonitis (4.3% in both cases), followed by obstruction from omental wrapping (3.7%). Univariate analysis showed that patients with catheter dysfunction or requiring catheter replacement were younger, with a lower body mass index and body surface area (P<.05). There was a significant association of wound infection and post-operative incisional hernia with catheter replacement. Omentectomy was associated with a low incidence rate of catheter dysfunction/replacement in the univariate and logistical regression analyses (odds ratio: 0.275; 95% confidence interval: 0.101-0.751; P<.012). CONCLUSIONS: Our catheter placement technique offers a low complication rate and good results in the first year after surgery. Except for omentectomy, we did not discover any risk factors for catheter replacement in our study population. Omentectomy had a protective effect in terms of catheter replacement.

Many surgeons support some sort of restriction of the gastric pouch outlet by placing a ring around the gastric reservoir. Previous studies have shown positive results of banded gastric bypass (BGBP); however, there are not many comparative long-term studies to assess the real advantage of placing a ring during gastric bypass (GBP) surgery. This study aims to evaluate the long-term outcome of patients subjected to BGBP and nonbanded GBP procedures. We studied 260 retrospective, nonrandomized obese patients who underwent BGBP and 218 patients without the ring (i.e., GBP). They were followed up for 10 years, and the following parameters were evaluated: excess weight loss (EWL), quality of life (QOL), food tolerance, and correction of comorbidities. The study was approved by the Committee on Ethics, and all the patients gave their informed consent. There is a significant difference in %EWL from the third year until the tenth year of observation, with the proportion being 82% in BGBP versus 63% in nonbanded GBP patients at the end of the study. Although there was some increased intolerance to food intake in the BGBP patients, this was not felt to reduce the QOL. The outcome in terms of comorbidities was not conclusive. There is a clear advantage in terms of %EWL in the BGBP patients. No differences in QOL were found in both groups. Further, selecting the right type of material and the right size of the ring is important to improve results and avoid complications.

BACKGROUND: in emergency surgery, colorectal mortality is very high compared with elective surgery. An alternative is placement of endoscopic stents to correct the bowel obstruction and then allow elective surgery. Moreover, it is possible to use stents in the palliative treatment of patients at high surgical risk or with unresecable tumors. The aim of this study is to evaluate the rates of technical and clinical success and complications of colorectal stent placement over the past 5 years. METHODS: retrospective study of 33 patients in which stents were placed since 2006 to 2011. Variables were analyzed: 1) the indication (palliation or "bridge to surgery"), 2) rates of technical success and clinical success, and 3) complications (perforation, migration, bleeding, and reocclusion). RESULTS: in 24 patients the prosthesis was placed as a palliative treatment (72.7%) and in 9 cases as a "bridge to surgery". The technical success rate was 87.87% and 82.14% clinical success. There were five cases of bowel perforation with high pneumoperitoneum and a case of microperforation (18.1%). Five patients had reocclusion (17.2%); there were 3 and 4 with bleeding and migration. Three patients died within 24 hours after endoscopic treatment. In 9 cases of "bridge to surgery," technical success was 100% and 77% clinical success. One patient required emergency surgery due to migration of the prosthesis and reocclusion and another colonic perforation. CONCLUSIONS: endoscopic treatment is a good option as a transitional step to elective surgery or palliative treatment. But serious complications such as perforation or reocclusion should be considered.

BACKGROUND: Endoprostheses are commonly used in the treatment of biliary disorders. The frequency of and potential risk factors for stent migration, however, remain largely unknown. OBJECTIVE: To determine how often biliary duct stents migrate proximally and to quantify the influence of specific risk factors on the occurrence of stent migration. PATIENTS METHODS AND RESULTS: We analyzed the occurrence of stent migration among the 410 stents for which follow-up data were available between January 1995 to December 1998. In 272 cases, we performed endoscopic sphincterotomy. Results demonstrated incidence rates of 4.4% for proximal biliary stent migration iatrogenic strictures were significantly associated with proximal biliary stent migration. CONCLUSIONS: Iatrogenic strictures were significantly associated with proximal common bile duct migration and the association between sphincterotomy and proximal migration failed to reach statistical significance.
