Liberal versus Modified Intraoperative Fluid Management in Abdominal-flap Breast Reconstructions. A Clinical Study.

BACKGROUND: The outcome of reconstructive microsurgery is influenced by the intraoperative anesthetic regimen. The aim of this study was to compare the impact on the intra- and postoperative complication rates of our modified fluid management (MFM) protocol with a previously used liberal fluid management protocol in abdominal-flap breast reconstructions. METHODS: This retrospective study analyzed adverse events related to secondary unilateral abdominal-flap breast reconstructions in two patient cohorts, one with a liberal fluid management protocol and one with a MFM protocol. In the MFM protocol, intravenous fluid resuscitation was restricted and colloid use was minimized. Both noradrenaline and propofol were implemented as standard in the MFM protocol. The primary endpoints were surgical and medical complications, as observed intraoperatively or postoperatively, during or shortly after the hospital stay. RESULTS: Of the 214 patients included in the study, 172 patients followed the MFM protocol. Prior radiotherapy was more frequent in the MFM protocol. Surgical procedures to achieve venous superdrainage were more often used in the MFM cohort. Intraoperative as well as postoperative complications occurred significantly more frequently in the liberal fluid management cohort and were specifically associated with partial and total flap failures. Prior radiotherapy, additional venous drainage, or choice of inhalation agent did not have an observable impact on outcome. CONCLUSIONS: The incidence of adverse events during and after autologous breast reconstructive procedures was reduced with the introduction of an MFM protocol. Strict intraoperative fluid control combined with norepinephrine and propofol was both beneficial and safe.

Intrathoracic Breast Transposition: A New Method in the Treatment of Bronchopleural Fistula and Empyema.

A bronchopleural fistula (BF) is a life-threatening complication. Optimal management of a BF is still debated although surgery remains the preferred treatment. Usually, the fistula is a result of inadequate healing at the bronchial stump after pneumonectomy. Successful closure of a BF after pneumonectomy depends on evacuation of empyema, coverage of the suture line after fistula closure with vascularized tissue, and obliteration of the residual pleural cavity. Extrathoracic muscles and omentum are the first choice for intrathoracal transposition. We report a unique case of a cachectic female patient with a BF from the left main stem bronchus complicated with empyema following right-sided pneumonectomy. Previous surgeries excluded the use of extrathoracic muscles or only omentum. The BF could not be closed with sutures. Using a parachute technique, omentum was sutured into the fistula opening resulting in a tension-free fistula closure. A well-vascularized breast was transposed into the residual pleural cavity to obliterate dead space and to support the omentoplasty, so it would be able to withstand changes in intrathoracic pressure. The postoperative course was uneventful. Tension-free closure of a BF can be obtained by suturing well-vascularized tissue into the fistula opening using a parachute technique. Intrathoracic breast transposition could be a new option in the treatment of a BF and associated empyema in a female patient. In selected patients, a large breast can obliterate the dead space after pneumonectomy and support the omentoplasty.
