A Creeping Malaise Leading to Calamity: Herpes Esophagitis Perforation.

Herpes simplex virus is an uncommon cause of esophagitis and particularly so in immunocompetent individuals. Although the common presentation tends to be odynophagia and/or dysphagia, fever, and retrosternal chest pain, there are variations and rarely it can present more ominously as esophageal rupture. We report a rare case of esophageal perforation with penetration into the vertebral space secondary to chronic herpes simplex virus esophagitis in a 71-year-old immunocompetent woman. This is the second known such occurrence. The patient had a long stay in the hospital but recovered from the condition and was followed up for 1 year after initial presentation.

Management of Intravenous Infiltration Injuries.

BACKGROUND: Intravenous (IV) lines are ubiquitous in hospital settings. These lines can malfunction, leaking noxious contents into subcutaneous tissue. Existing literature describes invasive intervention and complex treatment protocols. These persist despite significant changes in the composition and administration of IV agents. The purpose of this study is to examine the consequences of IV infiltrations at a tertiary medical center to update protocols and treatment algorithms. MATERIALS AND METHODS: This study is an observational, retrospective chart review performed at a tertiary care medical center. All inpatient plastic surgery consultations for IV infiltration were reviewed from 2011 to 2017. Patients were included if IV infiltration was suspected or documented. Data were collected for each injury regarding patient demographics, substance, and intervention. RESULTS: The plastic surgery service evaluated 381 IV infiltration injuries from 2011 to 2017, with 363 meeting the criteria. Injuries per year progressively increased, with 32 consultations in 2011 and 102 consultations in 2017. The vast majority of injuries identified (91%) were treated with only elevation and observation. The minority consisted of wound care (7%) performed by nursing or any form of incision, aspiration, or antidote injection (2%) performed by the physician. Of the 363 injuries, the most common infiltrates were noncytotoxic (35%), radiographic contrast (27%), and known vesicants (18%). Interestingly, a large portion of consultations were requested by other surgical services (32%). CONCLUSIONS: Although there is an increase in expert involvement for cases of IV infiltration injuries, the vast majority of these injuries are managed with minimal intervention. This is most likely owing to recent changes that have decreased the potential for harmful infiltration. Contrary to existing literature, invasive intervention is almost never indicated.

Extravasation injury in a paediatric population.

BACKGROUND: Extravasation occurs when a drug is inadvertently administered outside of the vein. Depending on the substance involved, this may lead to tissue necrosis with significant long-term morbidity. Children, particularly neonates, are particularly susceptible to extravasation with up to 70% of children in neonatal intensive care unit having some form of extravasation injury. These injuries are commonly referred to plastic surgeons for ongoing management. METHODS: We prospectively collected information on all extravasation injuries referred to the plastic surgery department in a children's hospital over an 18-month period. Data collected included the agent involved in the extravasation, treatment and outcomes. RESULTS: In total, there were 43 extravasation injuries recorded on the hospital risk management system during the period of this study. All of these were referred to the plastic surgery team for ongoing management. Five patients (11%) underwent washout of their injuries. Three patients (7%) suffered injuries, which led to significant tissue necrosis, delayed healing and prolonged morbidity. CONCLUSION: Smaller infants, particularly those being cared for in an intensive care setting, are at increased risk for extravasation injury. Early referral and treatment of high-risk extravasation injuries may reduce the incidence of tissue loss and morbidity.

Giant cell tumor of the eleventh thoracic vertebra in a pediatric patient: an interesting case report and comprehensive literature review.

INTRODUCTION: Giant cell tumors of the mobile spinal column are very rare tumors, especially in the pediatric age group. Although they are benign tumors, they have locally aggressive growth pattern and high risk of recurrence. CASE PRESENTATION: We report a 15-year-old female patient with thoracic giant cell tumor who underwent percutaneous vertebroplasty and had cement extravasation into the spinal canal. Because of the deterioration of the patient's neurological condition, total enbloc spondylectomy and cement excision were performed. She underwent instrumentation and fusion procedures in order to prevent spinal instability. CONCLUSION: The main purpose of the treatment is gross total resection of the giant cell tumor. However, adjuvant methods such as denosumab should be added to the treatment protocol in patients who are older than 2 years old and can not undergo gross total resection due to tumor size and anatomic localization.

Surgical treatment of extravasation injuries: experience of the Hospital das Clínicas, Faculty of Medicine, University of São Paulo. / Opções de tratamento cirúrgico em lesões cutâneas por extravasamento acidental de drogas: experiência do Hospital das Clínicas da Faculdade de Medicina da USP.

OBJECTIVE: to report the experience of the Division of Plastic Surgery of the Hospital das Clínicas of the Medical School of the University of São Paulo in the treatment of cutaneous lesions due to accidental extravasation of drugs. METHODS: we included patients with lesions due to extravasation of drugs over a period of 18 months. We retrospectively evaluated the following parameters: age, diagnoses during hospitalization and comorbidities, serum levels of albumin and hemoglobin, place of hospitalization, drug involved, anatomic segment affected, therapeutic management and death during hospitalization. RESULTS: we followed-up 14 patients. The main drug involved was noradrenaline (21%). All patients underwent debridement of tissue necrosis. Three patients were submitted to flaps after preparation of the wound bed with negative pressure therapy, with good results. Seven patients had no definitive treatment of their lesions due to lack of clinical conditions. CONCLUSION: in patients with favorable clinical conditions, the definitive treatment with flaps was adequate for cases of wounds due to extravasation of drugs in the subcutaneous tissue when there was exposure of noble structures.

Se lo ubica dentro del contexto de los otros dos tratamientos: el de urgencia y el clínico. Se señala que el tipo de citostático utilizado y el estado clínico de paciente influyen en esta decisión.

Surgical treatment in peripheral cytostatic extravasations is analysed. It discusses when and how to perform it. It is placed within the context of the other two treatments: the emergency and the clinical. It is pointed out that the type of cytostatic used and the clinical status of the patient influence this decision.

Utility of Magnetic Resonance Imaging in the Surgical Management of Drug Extravasation: A Case Report.

We report a case of phenytoin extravasation complicated by eschar formation. Pre-operative MRI study showed a large non-enhancing area over the dorsum of the imaged right wrist and hand corresponding with the site of phenytoin extravasation and raising the suspicion of subcutaneous tissue necrosis. The MRI findings correlated well with the intra-operative findings. We believe that pre-operative MRI in drug extravasation cases can characterise the type of soft tissue injury and define the extent of injury. This helps the surgeon in the surgical approach and treatment options.

Epirubicin extravasation: consequences of delayed management.

Epirubicin is an anthracycline chemotherapy agent used for treatment of several cancers including oesophageal, breast and gastric. Extravasation is a well-recognised and serious complication of any intravenous therapies but especially chemotherapeutic agents. Signs of the injury can be subtle and without prompt recognition and treatment there can be extensive tissue damage and depending on location of injury this can result in significant functional loss. In this article, a case of delayed management of epirubicin extravasation from a cannula situated at the dorsum of the hand is discussed. Successful surgical reconstruction of the resulting substantial tissue damage using a radial forearm flap 21 days following injury is described.

Computed tomography contrast media extravasation: treatment algorithm and immediate treatment by squeezing with multiple slit incisions.

In our hospital, an adverse event reporting system was initiated that alerts the plastic surgery department immediately after suspecting contrast media extravasation injury. This system is particularly important for a large volume of extravasation during power injector use. Between March 2011 and May 2015, a retrospective chart review was performed on all patients experiencing contrast media extravasation while being treated at our hospital. Immediate treatment by squeezing with multiple slit incisions was conducted for a portion of these patients. Eighty cases of extravasation were reported from approximately 218 000 computed tomography scans. The expected extravasation volume was larger than 50 ml, or severe pressure was felt on the affected limb in 23 patients. They were treated with multiple slit incisions followed by squeezing. Oedema of the affected limb disappeared after 1-2 hours after treatment, and the skin incisions healed within a week. We propose a set of guidelines for the initial management of contrast media extravasation injuries for a timely intervention. For large-volume extravasation cases, immediate management with multiple slit incisions is safe and effective in reducing the swelling quickly, preventing patient discomfort and decreasing skin and soft tissue problems.

Treatment of benign biliary leaks with transhepatic placement of coated self-expanding metallic stents. / Tratamiento de fugas biliares mediante colocación transparietohepática de endoprótesis metálicas recubiertas.

OBJECTIVES: To analyze the safety and efficacy of percutaneous placement of coated self-expanding metallic stents (SEMS) in patients with biliary leaks. MATERIAL AND METHODS: This ethics committee at our center approved this study. We retrospectively reviewed all coated SEMS placed between October 2008 and September 2015. We analyzed patient-related factors such as the primary underlying disease, prior hepatic procedures, and clinical outcome. We evaluated the location, the number and type of leak (anastomotic or non-anastomotic), and the characteristics of the interventional procedure (number of stents deployed, location of the stents, technical success, and primary functionality). We recorded the complications registered. RESULTS: We studied 14 patients (11 men and 3 women). The mean follow-up period was 375.5 days (range 15-1920 days). Leaks were postsurgical in 12 patients. One patient developed an arteriobilioportal fistula. In another, the biliary leak occurred secondary to the rupture of the common bile duct after ERCP. A total of 23 coated SEMS were placed, including 21 Fluency® stents (Bard, Tempe, AZ, USA) and 2 Wallflex® stents (Boston Scientific, Galway, Republic of Ireland). The technical success of the procedure was considered total in 11 (78.6%) patients, partial in 2 (14.3%) patients, and null in 1 (7.2%) patient. The clinical outcome was good in 13 of the 14 patients. The mean period of primary functionality of the coated SEMS was 331 days (range 15-1920 days). No major complications were observed in 11 (78.6%) patients. CONCLUSIONS: Percutaneous placement of coated SEMS for the treatment of benign biliary leaks is safe and efficacious, with a high rate of technical and clinical success and a moderate rate of complications.

Onyx extravasation during embolization of a brain arteriovenous malformation.

During Onyx embolization to treat brain arteriovenous malformation (AVM), carefully observing the penetration of Onyx to the nidus is important in order to avoid complications such as hemorrhage, ischemia, and difficulty with microcatheter removal. We encountered a case of Onyx extravasation during embolization of a cerebellar AVM confirmed by surgical resection and pathological analysis. The patient was a 44-year-old man with Spetzler-Martin grade I cerebellar AVM who underwent Onyx embolization prior to resection of the brain AVM. While injecting Onyx into the nidus using the "plug-and-push" technique, Onyx extravasation was observed. Onyx injection was paused and subsequently restarted, thereby allowing continuation of embolization. An oblate Onyx cast that was entirely covered in cerebellar tissue was removed during total resection of the AVM, performed the same day. The surgically removed oblate Onyx cast did not contain brain tissue or vessel wall, and immunohistochemical staining against glial fibrillary acidic protein (GFAP) showed Onyx penetration into GFAP-positive cerebellar tissue. Onyx extravasation was confirmed based on intraoperative findings during resection as well as pathological findings. The patient has been followed for four years postoperatively, and adverse events caused by Onyx extravasation have not been observed. Unexpected cast of Onyx, remote from the vascular architecture of the AVM, may represent an intra-parenchymal extravasation.

Rectal perforation during defecography: extraluminal barium impaction removed by TEM (Transanal Endoscopic Microsurgery).

AIM: Defecography is the standard diagnostic technique for the diagnosis of functional disorders of the posterior pelvic compartment. However it has some limits as radiation exposure, low-contrast resolution, some degrees of embarrassment and discomfort for the patients. Furthermore it often fails to directly visualize the changes that affect the pararectal space. Here we present a never described case of rectal perforation after defecography with barium impaction removed by TEM (Transanal Endoscopic Microsurgery). CASE REPORT: We present a case of a 50 years old woman with extraluminal barium impaction due to perforation occurred during defecography. Both pelvic MR and endoanal ultrasound confirmed the presence of the extramural rectal mass below rectal mucosa. It was completely and safely removed using transanal endoscopic microsurgery (TEM). RESULTS: The barium impaction has been radically removed using transanal endoscopic microsurgery. The post-operative period was uneventful and the patient was discharged 3 days after the operation. She is asymptomatic after 6 months from surgery. CONCLUSION: Defecography is not completely safe and its use must be indicated only in selected cases. When a patient has complications during or after this investigation he must be referred to a specialistic centre where a tailored treatment can be performed. It is mandatory that the indication for defecography and other diagnostic functional investigations is given by a colorectal specialist KEY WORD: Barium Impaction, Defecography, Rectal Perforation, TEM (Transanal Endoscopic Microsurgery).
