Tension pneumothorax secondary to a gastropleural fistula in a traumatic diaphragmatic hernia

Complications of chest tubes: a focused clinical synopsis

PURPOSE OF REVIEW

Chest tube placement, or tube thoracostomy, is an invasive procedure designed to evacuate air and/or fluid from the thorax, whether emergent or elective. In the placement of these devices particular attention and effort must be made to understand safe and reliable anatomic techniques and device maintenance so as to avoid serious injury to the patient. This review focuses on complications of chest tube placement, with the emphasis on patient safety and error prevention.

RECENT FINDINGS

There is a paucity of high-quality recent literature on tube thoracostomy complications. With the advent of value-driven healthcare, increasing emphasis is being placed on appropriate procedural indications, procedural safety, and patient satisfaction. Good clinical outcomes are critical to achieve and maintain in this context.

SUMMARY

Given the high volume of tube thoracostomies globally, greater awareness of potential complications and preventive strategies is needed. The authors attempt to bridge this important gap.

Complications of needle thoracostomy: A comprehensive clinical review

Needle thoracostomy (NT) is a valuable adjunct in the management of tension pneumothorax (tPTX), a life-threatening condition encountered mainly in trauma and critical care environments. Most commonly, needle thoracostomies are used in the prehospital setting and during acute trauma resuscitation to temporize the affected individuals prior to the placement of definitive tube thoracostomy (TT). Because it is both an invasive and emergent maneuver, NT can be associated with a number of potential complications, some of which may be life-threatening. Due to relatively common use of this procedure, it is important that healthcare providers are familiar, and ready to deal with, potential complications of NT.

Gastropleural fistula: a rare complication of ewing sarcoma

Gastropleural fistula (GPF) is a rare condition that can occur as a consequence of prior pulmonary surgery, trauma, or malignancy. Conservative management usually fails, and gastrectomy and even thoracotomy is often required, especially in debilitated patients. We present a patient with GPF who had a history of Ewing's sarcoma. Diagnosis of GPF was confirmed by upper gastrointestinal system endoscopy and radiographic contrast examination, and the patient underwent a laparoscopic wedge resection of the fistula. To our knowledge, this is the first report of a GPF, in the formation of which recurrence of Ewing's sarcoma had played a role and in the treatment of which wedge resection of the fistula was performed. Laparoscopic treatment of GPF may be associated with less morbidity and should be considered as the initial procedure of choice.

Gastropleural fistula: rare entity with unusual etiology

Gastropleural fistula is a rare condition. We report a case where fistula developed iatrogenically during repeated intercostal drainage tube insertions for empyema.

Pleural effusions of extravascular origin

Most pleural effusions are caused by hydrostatic and oncotic pressure imbalance, inflammation or infection, or abnormalities in lymphatic drainage. A select number of effusions are caused by fluid of extravascular origin. Some of these effusions result from complications of treatment, whereas others are a ramification of the underlying disease. The incidence, pathogenesis, clinical presentation, chest radiographic manifestations, pleural fluid analysis, diagnosis, and management are discussed.

[Traumatic diaphragmatic rupture with delayed unusual disclosure]

The authors report the case of a delayed presentation of a traumatic diaphragmatic rupture in a 22-year-old patient admitted to hospital for a minor surgical procedure under general anaesthesia. Nine months before, he had a road traffic accident with a minor thoracic trauma. Three days after surgery, the patient was readmitted for a tension hydrothorax due to the herniation and the perforation of the stomach into the left pleural cavity. Such a delayed presentation of a traumatic diaphragmatic rupture remains uncommon. The peroperative ventilatory factors involved in the development of the hernia are discussed.

Tension Pneumothorax: Etiology, Diagnosis, Pathophysiology, and Management

The normally air-free pleural cavity exists at subatmospheric pressure to promote pleural apposition and proper lung excursion. Owing to its unique bilayer structure, air introduced into this space either from within the thoracic cavity or from an extrathoracic source causes pleural separation and simple pneumothorax (PTX). Most simple pneumothoracies of a small or static volume in healthy patients do not appreciably impair cardiopulmonary function despite variable collapse of the lung. If increasing pressure develops within this pleural air collection, however, a cascade of pathophysiological changes can result from altered anatomical positions of heart, lung, and great vessels. The development of increasing pressure within the pleural space, with resultant ipsilateral lung collapse and hemithoracic expansion into the mediastinum and the contralateral lung, is termed tension pneumothorax (TPTX). The exact incidence of TPTX is unknown, but it is reported in up to 2 to 3% of all pneumothoracies. Certain medical and surgical disease states—many found within the critical care environment—place patients at higher risk for development of TPTX and also limit physiological tolerance to TPTX once it occurs. Although physical examination and chest radiography generally confirm the occurrence of TPTX, physiological monitoring may herald the development of increasing intrapleural pressure. Expeditious recognition and pleural decompression are necessary to prevent the untoward hemodynamic and respiratory consequences of TPTX. Significant morbidity and mortality may arise from TPTX if treatment is unduly delayed, particularly in mechanically ventilated patients.
