Endoscopic Vacuum Therapy Significantly Improves Clinical Outcomes of Anastomotic Leakages After Esophagectomies

“Anastomotic leakages continue to be a highly challenging complication in esophageal surgery. According to the literature, the risk of anastomotic leakage after esophagectomy ranges between 4 and 35%. The location of the anastomotic leakage is a significant factor in determining patient outcomes. Notwithstanding, cervical anastomoses bear a higher risk for leakage; the consequences of an intrathoracic (mediastinal) leakage are usually more devastating. A leakage into the thoracic cavity typically leads to mediastinitis and severe pneumonia and contributes to the significant mortality rates in esophageal surgery. In contrast, cervical anastomotic leakages tend to frequently present as wound infections often only requiring external drainage”

“The clinical outcomes strongly depend on an early diagnosis and appropriate treatment, which can extent over several weeks or even months. In the past, the mainstay of treatment was based on surgical repair, external drainage of sepsis via chest tubes, and interventional treatment modalities like endoscopic stent deployment or clipping. In 2008, endoscopic vacuum-assisted closure (eVAC) therapy was successfully applied in patients with anastomotic leakages after esophagectomies. As in other vacuum-assisted wound therapies, eVAC cleans the defect by reducing the amount of exudative fluids and necrotic tissue, thus accelerating the healing process by contributing to a better local perfusion as well as through the formation of granulation tissue.”

Negative Pressure Wound Therapy for Surgical-site Infection

“Despite improvement in infection control, SSIs remain a common cause of morbidity after abdominal surgery. SSI has been associated with an increased risk of reoperation, prolonged hospitalization, readmission, and higher costs. Recent retrospective studies have suggested that the use of negative pressure wound therapy can potentially prevent this complication.”

Use of lytics in patients with pleural empyema

“Parapneumonic effusions evolve through a spectrum of three stages. The initial exudative stage (stage 1; analogous to simple parapneumonic effusion) is characterised by an increased outpouring of fluid into the pleural space mediated by capillary permeability. If left
untreated, persistent inflammation with the associated rise in fluid plasminogen activator inhibitor causes a decrease in fluid fibrinolytic concentrations. During this second stage (stage 2; fibrinopurulent stage), as the effusion becomes infected, septations and adhesions
induced by fibrin deposition divide the space into pockets or locules. With the proliferation of fibroblasts and the formation of a pleural peel, lung expansion becomes restricted and can result in a non-expandable lung. It is important to initiate all medical treatment before this
final so-called organising stage (stage 3) ensues.”

Management of Empyema

“Empyema thoracis, from the Greek, is defined as ‘‘pus in the chest.’’ The most common precursor of empyema is bacterial pneumonia and subsequent parapneumonic effusion. Other causes of empyema include bronchogenic carcinoma, esophageal rupture, blunt or penetrating chest trauma, mediastinitis with pleural extension, infected congenital cysts of the airway and esophagus, extension from sources below the diaphragm, cervical and
thoracic spine infections, as well as postsurgical etiologies.”

Management of the complex duodenal injury

“Duodenal trauma is a rare occurrence existing in 1–4.7% of all abdominal trauma. Its posterior and partially retroperitoneal location shields it from most traumatic mechanisms. Colloquially referred to as the ‘surgical soul’, its proximity to complex regional anatomy makes duodenal trauma particularly at risk for biliary, pancreatic and major vascular injury with 68–86.5% of patients sustaining an associated injury.”

Damage control in penetrating duodenal trauma

“The overall incidence of duodenal injuries in severely injured trauma patients is between 0.2 to 0.6% and the overall prevalence in those suffering from abdominal trauma is 3 to 5% 1,2. Approximately 80% of these cases are secondary to penetrating trauma, commonly associated with vascular and adjacent organ injuries. These associated injuries create a significant challenge towards the early diagnosis and appropriate management. Therefore, defining the best surgical treatment algorithm remains controversial. Mild to moderate duodenal trauma is currently manage via primary repair and simple surgical techniques. However, severe injuries have required complex surgical techniques (duodenal diverticulization, pyloric exclusion with or without gastrojejunostomy and pancreatoduodenectomy) without significant favorable outcomes and consequential increase in the rates of mortality.”

Vascular injury in hernia repair

“Complications are known to occur at each and every step of hernia surgery. Applying caution while performing each step can save the patient from a lot of morbidity. One starts by applying strict patient selection criteria for endoscopic hernia repair, especially in the initial part of ones learning curve. A thorough knowledge of anatomy goes a long way in avoiding most of the complications seen in hernia repair. This anatomy needs to be relearned from what one is used to, as the approach is totally different from an open hernia repair. And finally, learning and mastering the right technique is an essential prerequisite before one ventures into inguinal hernia repair.”

“The most important preoperative precaution is proper patient selection prior to surgery, especially in the initial part of the learning curve. Ideally, direct or small indirect hernias are best. Large hernias, obese patients and irreducible, obstructed hernias are best avoided. An absolute contraindication is strangulated hernia. Also a detailed work-up of elderly patients to assess cardiorespiratory status is mandatory to ensure a safe outcome.”
