Clinical analysis of 5 cases of odontogenic maxillofacial-neck-mediastinal infection treated with negative pressure sealing drainage / 口腔疾病防治

Objective @#To explore the effect of negative pressure sealing drainage on the treatment of maxillofacial-neck-mediastinal infection in multiple spaces.@*Methods@# Vacuum sealing drainage (VSD) was applied in five patients with maxillofacial-neck-mediastinal infection caused by odontogenic infection accompanied by diabetes or renal failure and other systemic diseases. After extensive debridement, a negative pressure drainage sponge was placed in the pus cavity and then the wound was closed. Continuous negative pressure drainage was continued after the operation. At the same time, multidisciplinary consultation was applied to control basic diseases and, strengthen anti-inflammatory responses, and nutrition and other systemic treatments were applied.@*Results@#Four patients underwent continuous negative pressure drainage and successful removal of the negative pressure sponge after inflammatory symptoms subsided. One patient′s inflammatory symptoms became more serious after the operation, and we performed another operation to change the placement of the negative pressure sponge. All 5 patients underwent VSD with negative pressure sponge replacement ranging from 1 to 3 times during treatment. After multidisciplinary consultation, they were all cured and discharged from the hospital.@*Conclusion@#For infection of the mediastinum, maxillofacial region and neck, local treatment and systemic treatment are emphasized, as well as the treatment of infected lesions and basic diseases. Negative pressure closure and drainage technology promotes the alleviation of inflammation, and multidisciplinary combined treatment is beneficial for the control of basic diseases.

Use of advanced flap and microsurgery techniques in the resolution of mediastinitis as a complication of cardiac surgery

In the majority of cases, mediastinitis is a potential complication in any cardiac surgical procedure. The objective of this case report is to accurately describe how the combination of microsurgery and soft tissue flaps can be an effective therapeutic alternative in the treatment of mediastinitis as a complication of cardiac valve replacement. Female 63-year-old patient with a background of obesity, hypertension and extense cardiac interventions, she was programmed for necrosectomy with left pectoralis flap technique. Mediastinitis, although a rare complication of the sternotomy performed in cardiac surgery, occurring in 1-2%, carries a high mortality rate.  Early diagnosis of mediastinitis after cardiac surgery requires high clinical suspicion, initially making the diagnosis may be difficult, risk factors should be considered. An early surgical approach can reduce the morbidity and mortality of this condition. The pectoralis flap should be considered as a safe therapeutic option.

Empyema and mediastinal abscess in pyriform sinus fistula: A case report / 世界急诊医学杂志（英文）

@#Though notorious for its tendency to induce recurrent neck abscess, pyriform sinus fistula is of importance despite its rarity. It usually presents diagnostic and therapeutic challenges. Because of post-infectious fibrosis, the embryologic origin of pyriform sinus fistula is difficult to appreciate in certain cases. Here we present a case with empyema and mediastinal abscess caused by pyriform sinus fistula and share our experience in the treatment of this patient.

Treatment Experience of Continuous Negative Pressure Drainage in the Acute Anterior Mediastinal Infection of Oropharyngeal Origined / 中国肺癌杂志

BACKGROUND@#Mediastinal infection is a serious infection of mediastinal connective tissue, with more complications and higher mortality. Application of broad-spectrum antibiotics and nutritional support, early sufficient drainage is the key to successful treatment. In the mode of drainage, this paper discusses the application of continuous negative pressure drainage technique to treat acute anterior mediastinal infection of severe mouth pharynx source, and the good results are summarized and shared.@*METHODS@#In January to December in 2017, a total of 17 cases treated acute mediastinal infection is derived from the throat, has formed a mediastinal abscess, surgery adopts retrosternal counterpart negative pressure drainage way, namely the sternum nest and free sternum xiphoid process under the incision on the first mediastinal clearance, make breakthrough and placed drainage device, suture closed wound, continuous negative pressure drainage, negative pressure using 3 cm-5 cm water column.@*RESULTS@#Among the 17 patients, 14 patients were relieved by continuous negative pressure drainage, and then the drainage tube was removed. In 2 cases, the infection broke into the right thoracic cavity, and the closed drainage caused the negative pressure to disappear, and the negative pressure drainage was replaced by the conventional drainage, and the drainage tube was removed after the drainage tube was clear. One patient had formed a mediastinal abscess incision drainage time later, complicated with septic shock and sepsis, resulting in the death of multiple organ failure.@*CONCLUSIONS@#The traditional treatment of severe acute mediastinal infection is sternal incision and drainage. Continuous negative pressure drainage adequate drainage of mediastinal can relieve patients' pain, effusion, and avoid the dressing out repeatedly. It is an effective method. However, there are limitations in this method, which need to be further optimized.

Conservative treatment and surgical treatment of cervical cellulitis combineing mediastinal pleural abscess / 临床耳鼻咽喉头颈外科杂志

Objective:To explore the diagnosis, treatment and curative effect of cervical cellulitis combineing mediastinal pleural abscess. Method:Clinical data of 37 patients with the cervical cellulitis and mediastinal pleural abscess were analyzed, all patients were confirmed using ultrasond, X-ray, CT, puncture and microbiology examination. The result will analysis the diagnosis, treatment and curative effect through the comparison of conservative treatment and surgical treatment. Result:Twenty-three cases of patients were underwent tracheotomy because of difficulty in breathing and successfully extubated after treatment. Nine cases of patients were given anti-infection treatment and recovered after conservative treatment. Twenty-one cases of neck multiple pus cavity were underwent cavity incision, full removal of necrotic tissue and pipe flushing; 7 cases of patients with neck and mediastinal abscess and within which 2 cases were with toxic shock were underwent adequate drainage of lavage and abscess incision through jugular joint path; the companion of pyothorax in 2 cases were underwent the chest closed drainage. All patients were giving sensitive antibiotic after drug sensitive test, anti-shock treatment and supportive treatment. All the patients were recovered and discharged. The average hospitalization days with conservative treatment of these patients were 15.7 days, and the average hospitalization days with surgical treatment of patients were 25.3 days. Conclusion:The condition of cervical cellulitis is complex, a few case can be cured with conservative treatment. The others progress rapidly when merging mediastinal pleural abscess can cause serious complications, surgical treatment is risky, fully abscess incision, lavage drainage and combine with sensitive antibiotics and supportive treatment are the keys to therapy.

A Novel Mediastinal Drainage Tube for Mediastinitis

Mediastinitis is a life-threatening disease, and effective drainage is needed to treat mediastinitis with abscess formation. We recommend an alternative drainage method using chest tube binding with a Silastic Penrose drainage tube. The use of a Silastic Penrose drainage tube may help to manage mediastinitis with abscess formation. This method facilitates effective draining and prevents tissue adhesion.

A Case of Retropharyngeal Abscess and Mediastinal Abscess with Dyspnea / 소아알레르기및호흡기학회지

Retropharyngeal abscess is a deep neck infection that causes an immediate life-threatening emergency with potential for airway compromise and other catastrophic complications. Mediastinal abscess is also a serious and potentially fatal process. Thus, both early diagnosis and adequate treatment of these diseases are critical. We report a case of dyspnea caused by retropharyngeal abscess and mediastinal abscess in a 9-month-old male patient. The patient had continuous fever and cough after foreign body removal, but had only been diagnosed as, and been treated for, bronchiolitis. He underwent surgical abscess drainage and systemic broad-spectrum antibiotics treatment successfully.

A Case of Spontaneous Submucosal Dissection of the Esophagus Accompanying Mediastinal Abscess / 대한소화기내시경학회지

Spontaneous submucosal dissection of the esophagus (SDE) is a rare disease, in which spontaneous submucosal spot bleeding or intramural hematoma leads to the tearing of the layers between submucosa and muscle of the esophageal wall without any definitive cause, and the pathogenesis of SDE has not been well documented yet. Typical symptoms of SDE are chest pain, hematemesis, dysphagia, and odynophagia. The laboratory tests are usually normal and symptoms could be mild and ambiguous, so the diagnosis of SDE is conducted with endoscopy or esophagogram in most cases. The prognosis of SDE is usually very good with just conservative cares such as fasting and fluid therapy Esophageal perforation complicated by SDE is very rare because symptoms od SDE usually bring the patients to hospital before perforation. Recently, we experienced a case of a 54 year-old male showing the endoscopic findings of SDE and complicated mediastinal abscess probably following esophageal perforation. The patient had social history of chronic heavy alcoholic ingestion and had symptoms of substernal pain, dysphagia, and odynophagia. The patient recovered after partial esophagectomy, abscess drainage and antibiotic therapy.

A Case of Mediastinal Tuberculous Abscess and Lymphadenitis after Bone Marrow Transplantation / 감염

After bone marrow transplantation (BMT), recipients can be complicated by infectious or non-infectious chest lesions such as mycobacterial infections or post- transplant lymphoproliferative disorders (PTLDs). BMT recipients usually face a lot of risks of mycobacterial infection because they have severely impaired cell- mediated immunity as a result of their underlying disease, chemotherapy, radiotherapy, acute or chronic graft-versus-host diesase (GVHD) and their treatment. We report a case of mediastinal tuberculous abscess and lymphadenitis after BMT, which mimicks PTLDs. 20 months before admission, BMT was performed on a 41 year-old woman who was diagnosed as chronic myelocytic leukemia. She showed acute and chronic GVHD with several infections of bacteria or viruses after BMT. In endemic area of tuberculosis such as Korea, PTLDs should be differentiated from pulmonary tuberculosis and tuberculous lymphadenitis.

A Case Report of Fatal Mediastinal Abscess Secondary to Odontogenic Infection

Modern antibiotic therapy and rapid surgical intervention have greately reduced the complication from the spread of odontogenic infections. Nevertheless, fatalities from dental infections continue to occur. One of the most threaded, and probably lethal form is the mediastinal abscess. This is a case of Ludwig's angina dissected along deep cervical planes into the mediastinum caused a virulent mediastinitis and abscess, computed tomography precisely delineated the extent of the infection. Incomplete debridement resulted in a residual abscess and persistent systemic sepsis that culminated in the patient's death. Aggressive antibiotic treatment of the orofacial cellulitis along with complete mediastinal drainage are recommended for optimal outcome.

A Case of Mediastinal Abscess following Esophageal Perforation / 대한소화기내시경학회지

We recently experienced a case of an elderly patient with mediastinal abscess, which is a rare complication of esophageal perforation, in whom dyspnea, chest pain and odynophagia were main clinical symptoms after eating cooked fish. During evaluation, upper mediastinal widening, with air-fluid level, and eaophageal perforation plugged with pus were detected by chest X-ray films and endoscopic examinatien. After draining of pus(about 300 cc) through the perforation site by careful manipulation of endoscope, inner wall of abacess cavity communicating with esophagus could be observed through esophago-mediastinal fistula. For further management, drainage procedure of mediastinal abscess, esophageal diversion and feeding gastrostomy were done.
