Objective: To evaluate prognostic differences between minimally invasive esophagectomy (MIE) and open esophagectomy (OE) in patients with surgery after a prolonged interval (> 12 wk) following chemoradiotherapy (CRT). Background: Previously, we established that a prolonged interval after CRT before esophagectomy was associated with poorer longterm survival. Methods: This was an international multicenter cohort study involving 17 tertiary centers, including patients who received CRT followed by surgery between 2010 and 2020. Patients undergoing MIE were defined as thoracoscopic and laparoscopic approaches. Results: A total of 428 patients (145 MIE and 283 OE) had surgery between 12 weeks and 2 years after CRT. Significant differences were observed in American Society of Anesthesiologists grade, radiation dose, clinical T stage, and histologic subtype. There were no significant differences between the groups in age, sex, body mass index, pathologic T or N stage, resection margin status, tumor location, surgical technique, or 90-day mortality. Survival analysis showed MIE was associated with improved survival in univariate (P= 0.014), multivariate analysis after adjustment for smoking, T and N stage, and histology (HR=1.69; 95% CI: 1.14-2.5) and propensity-matched analysis (P=0.02). Further subgroup analyses by radiation dose and interval after CRT showed survival advantage for MIE in 40 to 50 Gy dose groups (HR= 1.9; 95% CI: 1.2-3.0) and in patients having surgery within 6 months of CRT (HR =1.6; 95% CI: 1.1-2.2). Conclusions: MIE was associated with improved overall survival compared with OE in patients with a prolonged interval from CRT to surgery. The mechanism for this observed improvement in survival remains unknown, with potential hypotheses including a reduction in complications and improved functional recovery after MIE.

Background: Hybrid minimally invasive esophagectomy (HMIE) has been shown to reduce major postoperative complications compared with open esophagectomy (OE) for esophageal cancer. Objectives: The aim of this study was to compare short- and long-term health-related quality of life (HRQOL) following HMIE and OE within a randomized controlled trial. Methods: We performed a multicenter, open-label, randomized controlled trial at 13 study centers between 2009 and 2012. Patients aged 18 to 75 years with resectable cancers of the middle or lower third of the esophagus were randomized to undergo either transthoracic OE or HMIE. Patients were followed-up every 6 months for 3 years postoperatively and global health assessed with EORTC-QLQC30 and esophageal symptoms assessed with EORTC-OES18. Results: The short-term reduction in global HRQOL at 30 days specifically role functioning [-33.33 (HMIE) vs -46.3 (OE); P = 0.0407] and social functioning [-16.88 (HMIE) vs -35.74 (OE); P = 0.0003] was less substantial in the HMIE group. At 2 years, social functioning had improved following HMIE to beyond baseline (+5.37) but remained reduced in the OE group (-8.33) (P = 0.0303). At 2 years, increases in pain were similarly reduced in the HMIE compared with the OE group [+6.94 (HMIE) vs +14.05 (OE); P = 0.018]. Postoperative complications in multivariate analysis were associated with role functioning, pain, and dysphagia. Conclusions: Esophagectomy has substantial effects upon short-term HRQOL. These effects for some specific parameters are, however, reduced with HMIE, with persistent differences up to 2 years, and maybe mediated by a reduction in postoperative complications.

Supplemental Digital Content is available in the text Objective: Utilizing a standardized dataset with specific definitions to prospectively collect international data to provide a benchmark for complications and outcomes associated with esophagectomy. Summary of Background Data: Outcome reporting in oncologic surgery has suffered from the lack of a standardized system for reporting operative results particularly complications. This is particularly the case for esophagectomy affecting the accuracy and relevance of international outcome assessments, clinical trial results, and quality improvement projects. Methods: The Esophageal Complications Consensus Group (ECCG) involving 24 high-volume esophageal surgical centers in 14 countries developed a standardized platform for recording complications and quality measures associated with esophagectomy. Using a secure online database (ESODATA.org), ECCG centers prospectively recorded data on all resections according to the ECCG platform from these centers over a 2-year period. Results: Between January 2015 and December 2016, 2704 resections were entered into the database. All demographic and follow-up data fields were 100% complete. The majority of operations were for cancer (95.6%) and typically located in the distal esophagus (56.2%). Some 1192 patients received neoadjuvant chemoradiation (46.1%) and 763 neoadjuvant chemotherapy (29.5%). Surgical approach involved open procedures in 52.1% and minimally invasive operations in 47.9%. Chest anastomoses were done most commonly (60.7%) and R0 resections were accomplished in 93.4% of patients. The overall incidence of complications was 59% with the most common individual complications being pneumonia (14.6%) and atrial dysrhythmia (14.5%). Anastomotic leak, conduit necrosis, chyle leaks, recurrent nerve injury occurred in 11.4%, 1.3%, 4.7%, and 4.2% of cases, respectively. Clavien-Dindo complications ≥ IIIb occurred in 17.2% of patients. Readmissions occurred in 11.2% of cases and 30- and 90-day mortality was 2.4% and 4.5%, respectively. Conclusion: Standardized methods provide contemporary international benchmarks for reporting outcomes after esophagectomy. [ABSTRACT FROM AUTHOR]

Background Bronchial resection and reimplantation in surgical management of lung cancer is intended to spare lung parenchyma, with curative intent. We studied the incidence and management of anastomotic complications after such procedures. Methods We retrospectively reviewed charts of patients referred to our center for lung tumors who underwent bronchial resection and reimplantation from 1992 to 2011. Results A total of 108 patients were included. Sixty-eight percent were male, and mean age was 58 years. Sleeve lobectomies were performed in 100 patients, bronchial resections without lung parenchymal resection in 8 patients. Squamous cell carcinoma represented 46.3% of cases, carcinoid tumors 22.2%, and adenocarcinoma 18.5%. Mean time between surgery and first bronchoscopic examination was 4.47 days. During the follow-up, anastomotic abnormalities were detected in 23 patients (21.3%): malacic or fibrotic bronchial stenoses in 9 cases (39.1%), dehiscences in 7 (30.4%), obstructive granulomas in 4 (17.4%), and bronchopleural fistulas in 3 (13.0%). Endoscopic treatment was indicated in 14 patients (13%) and consisted of stent placement in 6 cases (26%), mechanical dilations in 3 (13%), laser treatment for 1 case of bronchomalacia (4.3%), and resection of granulomas in 4 (17.4%). No risk factors were identified as predisposing for bronchial complications. There was a trend toward lower 1-year survival in patients with bronchial complications compared with those without (71.9% versus 83.4%; p = 0.114). Conclusions Bronchial resection and reimplantation is a surgical procedure associated with an anastomotic complication rate of 21.3%, but only 13% required endoscopic management. Regular endoscopic surveillance is advised to detect and treat early complications. [ABSTRACT FROM AUTHOR]

Background: Bronchogenic cyst (BC) is a benign congenital mediastinal tumor whose natural course remains unclear. In adults, most BCs are removed by thoracotomy after complications. Currently, prenatal diagnosis is generally feasible and allows an early thoracoscopic intervention. The purpose of this retrospective study was to ascertain the best time for the operation. Methods: Reviewed were 36 patients (11 children, 25 adults) with a BC managed from 2000 to 2011. Clinical history, cyst size, duration of hospitalization, preoperative and postoperative complications, and detection of inflammatory elements were compared (Student t tests) between pediatric and adult patients. Results: In the pediatric group, diagnosis was made prenatally in 7 patients, during the neonatal period in 2, and later in 2. Nine were asymptomatic. In the adult group, 20 patients were treated for complications. Thoracotomy was performed in 2 children and thoracoscopy in 9 (no conversion). A thoracoscopic operation was performed in 9 adults (2 conversions), and 17 adults required additional procedures (4 pericardial and 9 lung resections, 3 bronchial, and 1 esophageal sutures). The average length of hospitalization was 4.45 days for children (3.33 days in the thoracoscopic subgroup) and 8 days for adults. Mean maximal cyst diameter was 2.2 cm in children and 6.5 cm in adults (p < 0.10). Pathologic study revealed inflammatory reaction in 2 children (18%) vs 21 adults (84%; p < 0.001). Conclusions: Early surgical resection of BCs provides better conservation of pulmonary parenchyma, a lower incidence of inflammatory lesions, and a reduced rate of complications, and should be proposed after prenatal diagnosis, between the 6th and 12th month of life.

Background: Whereas proximal airways of patients undergoing lung cancer surgery are known to present specific microbiota incriminated in the occurrence of postoperative respiratory complications, little attention has been paid to distal airways and lung parenchyma considered to be free from bacteria. We have hypothesized that molecular culture-independent techniques applied to distal airways should allow identification of uncultured bacteria, virus, or emerging pathogens and predict the occurrence of postoperative respiratory complications. Methods: Microbiological assessments were obtained from the distal airways of resected lung specimens from a prospective cohort of patients undergoing major lung resections for cancer. Microorganisms were detected using real-time polymerase chain reaction (PCR) assays targeting the bacterial 16s ribosomal RNA gene and Herpesviridae, cytomegalovirus (CMV), and herpesvirus simplex. All postoperative microbiological assessments were compared with the PCR results. Results: In all, 240 samples from 87 patients were investigated. Colonizing agents were exclusively Herpesviridae (CMV, n = 13, and herpesvirus simplex, n = 1). All 16s ribosomal RNA PCR remained negative. Thirteen patients (15%) had a positive CMV PCR (positive-PCR group), whereas the remaining 74 patients constituted the negative-PCR group. Postoperative pneumonia occurred in 24% of the negative-PCR group and in 69% of the positive-PCR group (p = 0.003). Upon stepwise logistic regression, performance status, percent of predicted diffusion lung capacity for carbon monoxide, and positive PCR were the risk factors of postoperative respiratory complications. The CMV PCR had a positive predictive value of 0.70 in prediction of respiratory complications. Conclusions: When tested by molecular techniques, lung parenchyma and distal airways are free of bacteria, but CMV was found in a high proportion of the samples. Molecular CMV detection in distal airways should be seen as a reliable marker to identify patients at risk for postoperative respiratory complications. [Copyright &y& Elsevier]

Objective: Surgical management of massive hernias and complex gastroesophageal reflux disease requires a tension-free repair with reliable reflux control. The aim of this observation was to evaluate the functional results of a modified Collis-Nissen gastroplasty with a transverse widening fundoplasty. Methods: Between 1995 and 2007, 26 patients underwent a 3-cm cut elongation gastroplasty with a transverse widening of the fundus followed by a 3-cm total (n = 24) or partial (n = 2) fundoplication. Indications for the operation were symptomatic massive hiatal hernias (n = 4), hiatal hernias with Barrett''s esophagus (n = 8), or correction of previously failed antireflux fundoplications (n = 14). Barrett''s esophagus was documented in 19 of the 26 patients. Pre- and postoperative assessment included symptoms, barium swallow, endoscopy, manometry, and 24-hour pH monitoring. Results: There was no postoperative mortality. Complications were recorded in 6 patients. Median follow-up was 105 months. Reflux symptoms present in all patients before the operation were found in 5 patients postoperatively (P < .001). Radiologic assessment documented an intact fundoplication in all patients. Lower esophageal sphincter gradient increased from a mean of 7.5 to 15 mm Hg (P = .003). Acid exposure (17% preoperatively) decreased significantly to 1% postoperatively (P < .001). Endoscopically, mucosal damage quantification decreased (3.1 preoperatively to 1.5 postoperatively; P < .001). All mucosal breaks healed but the columnar-lined metaplasia persisted. Conclusions: This modified elongation gastroplasty provided a reliable repair for massive hernias, shortened Barrett''s esophagus, and reoperations. The lower esophageal sphincter gradient was restored and remained stable. Reflux exposure was reduced, and acute mucosal damage disappeared. Columnar-lined metaplasia remained unchanged.

Background: Reflux esophagitis is a significant problem after esophagectomy and gastric reconstruction. When mixed reflux damages the esophageal remnant or results in aspiration problems, appropriate medical management is in order. If medical management fails, a surgical option is available. This study reports results of a Roux-en-Y diversion in postesophagectomy patients affected by debilitating reflux complications. Methods: Between 1990 and 2006, 4 of 223 esophagectomy patients required surgical correction for mucosal damage to their esophageal remnant or repeat aspirations. Patient, clinical, operative, histopathologic, and postoperative data were collected. Results: Two of 3 patients with a substernal reconstruction underwent antrectomy with a 60-cm Roux-en-Y diversion. One patient with significant reflux disease and aspiration episodes also had a gastrobronchial fistula. The gastric interposition was defunctionalized, and a staged reconstruction with antrectomy and a Roux-en-Y diversion was completed. One patient with a prevertebral reconstruction had a Roux-en-Y diversion without antrectomy. There was no mortality and minimal morbidity. Two patients are asymptomatic and 2 are improved. Endoscopic assessment documented normal mucosa in the esophageal remnant for 2 of the 4 patients postoperatively; in 2 others, metaplastic columnar mucosa persisted. Active inflammation regressed in all 4 patients. Conclusions: Complete duodenal diversion with a 60-cm Roux-en-Y gastrojejunostomy is an effective operation to correct debilitating reflux complications after esophagectomy. Reflux symptoms are corrected and the mucosa is allowed to heal. The surgical approach is influenced by the position of the gastric transplant. Protection of the vascular supply to the gastric tube is the challenge of the operation. [Copyright &y& Elsevier]

Background: Long-term outcome of patients treated for a spontaneous esophageal rupture (Boerhaave’s syndrome) is seldom reported. Methods: From 1989 to 2004, 62 esophageal perforations were treated in a single institution. Eighteen patients presented with a spontaneous esophageal rupture. Among them, 15 could be treated with a transthoracic primary repair and constituted the material of the present study. A chart review was performed with special attention to survival, residual symptoms, and anatomic and motility disorders. Results: Three patients died postoperatively (20%). At last follow-up, 10 patients were alive and 2 had died from unrelated causes. At a median delay of 13 months (3 to 74), 7 patients accepted to undergo complementary investigations. None of them had any anatomic abnormality as checked by barium swallow. Six patients complained of mild symptoms from gastroesophageal reflux. Six patients (85%) presented with esophageal motility disorders on manometry and 4 (54%) had nocturne chronic reflux disease on pH monitoring. Two patients underwent endoscopic ultrasonography, of which one presented with a focal absence of one layer of the esophageal wall within the area of the suture. With time, no patient experienced recurrence, but one developed a cancer in the cervical esophagus. Conclusions: These results suggest that esophageal functional disorders are the rule after primary repair of a Boerhaave’s syndrome. Whether or not these findings are causal, coincidental, or related to the surgical treatment remains unclear. However, performance of routine postoperative explorations is strongly encouraged for a better understanding of this challenging condition. [Copyright &y& Elsevier]

Clamshell incision with transverse sternotomy is the approach of choice for bilateral lung transplantation when cardiopulmonary bypass becomes necessary or to improve exposure. Sternal dehiscence is a well-known complication of this approach. This results in chronic thoracic pain and contributes to a delayed pulmonary rehabilitation. Sternal dehiscence can be treated with conservative therapy, but severe dehiscence requires secondary surgical closure. Several techniques of osteosynthesis have been reported with conflicting results. We describe the first use of the STRAsbourg Thoracic Osteosyntheses System (STRATOS) devices in three cases of secondary sternal closure without infection after bilateral lung transplantation.
