BACKGROUNDMediastinal leakage (ML) is one of the most feared complications of esophagectomy. A standard strategy for its diagnosis and treatment has been difficult to establish because of the great variability in their incidence and mortality rates reported in the existing series.AIMTo assess the incidence, predictive factors, treatment, and associated mortality rate of mediastinal leakage using the standardized definition of mediastinal leaks recently proposed by the Esophagectomy Complications Consensus Group (ECCG).METHODSSeven Italian surgical centers (five high-volume, two low-volume) affiliated with the Italian Society for the Study of Esophageal Diseases designed and implemented a retrospective study including all esophagectomies (n = 501) with intrathoracic esophagogastric anastomosis performed from 2014 to 2017. Anastomotic MLs were defined according to the classification recently proposed by the ECCG.RESULTSFifty-nine cases of ML were recorded, yielding an overall incidence of 11.8% (95%CI: 9.1%-14.9%). The surgical approach significantly influenced the occurrence of ML: the proportion of leakage was 10.5% and 9% after open and hybrid esophagectomy (HE), respectively, and doubled (20%) after totally minimally invasive esophagectomy (TMIE) (P = 0.016). No other predictive factors were found. The 30- and 90-d overall mortality rates were 1.4% and 3.2%, respectively; the 30- and 90-d leak-related mortality rates were 5.1% and 10.2%, respectively; the 90-d mortality rates for TMIE and HE were 5.9% and 1.8%, respectively. Endoscopy was the first-line treatment in 49% of ML cases, with the need for retreatment in 17.2% of cases. Surgery was needed in 44.1% of ML cases. Endoscopic treatment had the lowest mortality rate (6.9%). Removal of the gastric tube with stoma formation was necessary in 8 (13.6%) cases.CONCLUSIONThe incidence of ML after esophagectomy was high mainly in the TMIE group. However, the general and specific (leak-related) mortality rates were low. Early treatment (surgical or endoscopic) of severe leaks is mandatory to limit related mortality.
Both anti-reflux procedures are safe and effective up to 1-year follow-up. PPI suspension rate, dysphagia requiring endoscopic dilatation, and disease-related quality of life are similar in the two patient groups. MSA is associated with less gas/bloat symptoms and increased ability to vomit and belch.
Esophagectomy is a major surgical procedure associated with a significant risk of morbidity and mortality. Minimally invasive esophagectomy is becoming the preferred approach because of the potential to limit surgical trauma, reduce respiratory complications, and promote earlier functional recovery. Various hybrid and total minimally invasive surgical techniques have been introduced in clinical practice over the past 20 years, and minimally invasive esophagectomy has been shown equivalent to open surgery concerning the short-term outcomes. Implementation of a minimally invasive esophagectomy program is technically demanding and requires a significant learning curve and the infrastructure of a dedicated multidisciplinary center where optimal staging, individualized therapy, and perioperative care can be provided to the patient. Both hybrid and total minimally invasive techniques of esophagectomy have proven safe and effective in expert centers. The choice of the surgical approach should be driven by preoperative staging, tumor site and histology, comorbidity, patient's anatomy and physiological status, and surgeon's experience.
Transoral stapling is a safe and effective technique. A repeat procedure is feasible in case of recurrent diverticulum. The use of traction sutures applied at the apex of the common septum before stapling might increase the long-term success of the technique.
