RESUMO
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 prior to esophagectomy was associated with poorer long-term survival. METHODS: This was an international multi-center cohort study involving seventeen tertiary centers, including patients who received CRT followed by surgery between 2010-2020. Patients undergoing MIE were defined as thoracoscopic and laparoscopic approach. RESULTS: 428 patients (145 MIE and 283 OE) had surgery between 12 weeks and two years after CRT. Significant differences were observed in ASA grade, radiation dose, clinical T stage, and histological subtype. There were no significant differences between the groups in age, sex, BMI, pathological 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 to 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 40-50Gy dose groups (HR=1.9; 95% CI 1.2 to 3.0), and in patients having surgery within six months of CRT (HR=1.6; 95% CI 1.1 to 2.2). CONCLUSION: MIE was associated with an improved overall survival compared to 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.
RESUMO
PURPOSE: To reduce perioperative risks among patients with a preoperative diabetes mellitus (DM) a total pancreatectomy (TP) might be a alternative to pancreatoduodenectomy (PD). This study aimed to compare the postoperative quality of life (QoL) of patients with preoperative DM undergoing PD or TP. METHODS: A single-centre retrospective study was conducted, all consecutive patients with preoperative DM undergoing PD or TP between 2011 and 2023 were identified in a prospective database. The primary endpoint was QoL, prospectively assessed using EORTC QLQ-C30 questionnaires at 3, 6, and 12 months after surgery and then annually until death. Secondary endpoints were morbidity and mortality. RESULTS: Seventy-one patients were included, 17 after TP and 54 after PD. Insulin-dependent DM occurred in 21 (39%) of the PD patients. QoL was worse after TP, especially in terms of physical functioning (-31.7 points; 95% CI: -50.0 to -13.3; P < 0.001), role functioning (-41.3 points; 95% CI: -61.3 to -21.3; P < 0.001), emotional functioning (-27.5 points; 95% CI: -50.4 to -4.6; P = 0.019), fatigue symptoms (20 points; 95% CI: 2.7 to 37.4; P = 0.024) and pain symptoms (30.2 points; 95% CI: 4.1 to 56.3; P = 0.024). The rates of postoperative major complications (29% vs. 35%; P = 0.853) and mortality (11% vs. 7%; P = 0.857) were similar between TP and PD. CONCLUSION: Postoperative morbidity and mortality were comparable between PD and TP, however QoL is significantly lower after TP. Importantly, patients with preoperative DM have a 60% chance of remaining noninsulin-dependent after PD.

Reasons for structural and outcome differences in esophageal cancer surgery in Western Europe remain unclear. This questionnaire study aimed to identify differences in the organization of esophageal cancer surgical care in Western Europe. A cross-sectional international questionnaire study was conducted among upper gastrointestinal (GI) surgeons from Western Europe. One surgeon per country was selected based on scientific output and active membership in the European Society for Diseases of the Esophagus or (inter)national upper GI committee. The questionnaire consisted of 51 structured questions on the structural organization of esophageal cancer surgery, surgical training, and clinical audit processes. Between October 2021 and October 2022, 16 surgeons from 16 European countries participated in this study. In 5 countries (31%), a volume threshold was present ranging from 10 to 26 annual esophagectomies, in 7 (44%) care was centralized in designated centers, and in 4 (25%) no centralizing regulations were present. The number of centers performing esophageal cancer surgery per country differed from 4 to 400, representing 0.5-4.9 centers per million inhabitants. In 4 countries (25%), esophageal cancer surgery was part of general surgical training and 8 (50%) reported the availability of upper GI surgery fellowships. A national audit for upper GI surgery was present in 8 (50%) countries. If available, all countries use the audit to monitor the quality of care. Substantial differences exist in the organization and centralization of esophageal cancer surgical care in Western Europe. The exchange of experience in the organizational aspects of care could further improve the results of esophageal cancer surgical care in Europe.

Importance: Preoperative skin antisepsis is an established procedure to prevent surgical site infections (SSIs). The choice of antiseptic agent, povidone iodine or chlorhexidine gluconate, remains debated. Objective: To determine whether povidone iodine in alcohol is noninferior to chlorhexidine gluconate in alcohol to prevent SSIs after cardiac or abdominal surgery. Design, Setting, and Participants: Multicenter, cluster-randomized, investigator-masked, crossover, noninferiority trial; 4403 patients undergoing cardiac or abdominal surgery in 3 tertiary care hospitals in Switzerland between September 2018 and March 2020 were assessed and 3360 patients were enrolled (cardiac, n = 2187 [65%]; abdominal, n = 1173 [35%]). The last follow-up was on July 1, 2020. Interventions: Over 18 consecutive months, study sites were randomly assigned each month to either use povidone iodine or chlorhexidine gluconate, each formulated in alcohol. Disinfectants and skin application processes were standardized and followed published protocols. Main Outcomes and Measures: Primary outcome was SSI within 30 days after abdominal surgery and within 1 year after cardiac surgery, using definitions from the US Centers for Disease Control and Prevention's National Healthcare Safety Network. A noninferiority margin of 2.5% was used. Secondary outcomes included SSIs stratified by depth of infection and type of surgery. Results: A total of 1598 patients (26 cluster periods) were randomly assigned to receive povidone iodine vs 1762 patients (26 cluster periods) to chlorhexidine gluconate. Mean (SD) age of patients was 65.0 years (39.0-79.0) in the povidone iodine group and 65.0 years (41.0-78.0) in the chlorhexidine gluconate group. Patients were 32.7% and 33.9% female in the povidone iodine and chlorhexidine gluconate groups, respectively. SSIs were identified in 80 patients (5.1%) in the povidone iodine group vs 97 (5.5%) in the chlorhexidine gluconate group, a difference of 0.4% (95% CI, -1.1% to 2.0%) with the lower limit of the CI not exceeding the predefined noninferiority margin of -2.5%; results were similar when corrected for clustering. The unadjusted relative risk for povidone iodine vs chlorhexidine gluconate was 0.92 (95% CI, 0.69-1.23). Nonsignificant differences were observed following stratification by type of surgical procedure. In cardiac surgery, SSIs were present in 4.2% of patients with povidone iodine vs 3.3% with chlorhexidine gluconate (relative risk, 1.26 [95% CI, 0.82-1.94]); in abdominal surgery, SSIs were present in 6.8% with povidone iodine vs 9.9% with chlorhexidine gluconate (relative risk, 0.69 [95% CI, 0.46-1.02]). Conclusions and Relevance: Povidone iodine in alcohol as preoperative skin antisepsis was noninferior to chlorhexidine gluconate in alcohol in preventing SSIs after cardiac or abdominal surgery. Trial Registration: ClinicalTrials.gov Identifier: NCT03685604.

OBJECTIVE: To determine the impact of delayed surgical intervention following chemoradiotherapy (CRT) on survival from esophageal cancer. BACKGROUND: CRT is a core component of multimodality treatment for locally advanced esophageal cancer. The timing of surgery following CRT may influence the probability of performing an oncological resection and the associated operative morbidity. METHODS: This was an international, multicenter, cohort study, including patients from 17 centers who received CRT followed by surgery between 2010 and 2020. In the main analysis, patients were divided into 4 groups based upon the interval between CRT and surgery (0-50, 51-100, 101-200, and >200 days) to assess the impact upon 90-day mortality and 5-year overall survival. Multivariable logistic and Cox regression provided hazard ratios (HRs) with 95% CIs adjusted for relevant patient, oncological, and pathologic confounding factors. RESULTS: A total of 2867 patients who underwent esophagectomy after CRT were included. After adjustment for relevant confounders, prolonged interval following CRT was associated with an increased 90-day mortality compared with 0 to 50 days (reference): 51 to 100 days (HR=1.54, 95% CI: 1.04-2.29), 101 to 200 days (HR=2.14, 95% CI: 1.37-3.35), and >200 days (HR=3.06, 95% CI: 1.64-5.69). Similarly, a poorer 5-year overall survival was also observed with prolonged interval following CRT compared with 0 to 50 days (reference): 101 to 200 days (HR=1.41, 95% CI: 1.17-1.70), and >200 days (HR=1.64, 95% CI: 1.24-2.17). CONCLUSIONS: Prolonged interval following CRT before esophagectomy is associated with increased 90-day mortality and poorer long-term survival. Further investigation is needed to understand the mechanism that underpins these adverse outcomes observed with a prolonged interval to surgery.

BACKGROUND : Endoscopic vacuum therapy (EVT) is a novel treatment for esophageal perforations. This study aimed to describe initial experience with EVT of esophageal perforations due to iatrogenic cause, Boerhaave syndrome, or other perforations not related to prior upper gastrointestinal surgery. METHODS : Data from patients treated with EVT for esophageal perforation at five hospitals in three European countries, between January 2018 and October 2021, were retrospectively collected. The primary end point was successful defect closure by EVT, with or without the use of other endoscopic treatment modalities. Secondary end points included mortality and adverse events. RESULTS : 27 patients were included (median age 71 years). The success rate was 89â% (24/27, 95â%CI 77-100). EVT failed in three patients: two deceased during EVT (septic embolic stroke, pulmonary embolism) and one underwent esophagectomy due to a persisting defect. Two adverse events occurred: one iatrogenic defect expansion during sponge exchange and one hemorrhage during sponge removal. Median treatment duration was 12 days (interquartile range [IQR] 6-16) with 1 sponge exchange (IQR 1-3). CONCLUSION : EVT is a promising organ-preserving treatment for esophageal perforations, with a success rate of 89â%. More experience with the technique and indications will likely improve success rates.

BACKGROUND: Mesh augmentation is a highly controversial adjunct of hiatus hernia (HH) surgery. The current scientific evidence remains unclear and even experts disagree on indications and surgical techniques. With an aim to avoid the downsides of both non-resorbable synthetic and biological materials, biosynthetic long-term resorbable meshes (BSM) have recently been developed and are becoming increasingly popular. In this context, we aimed at assessing outcomes after HH repair with this new generation of mesh at our institution. METHODS: From a prospective database, we identified all consecutive patients that underwent HH repair with BSM augmentation. Data was extracted from electronic patient charts of our hospital information system. Endpoints of this analysis included perioperative morbidity, functional results and recurrence rates at follow-up. RESULTS: Between December 2017 and July 2022, 97 patients (elective primary cases n = 76, redo cases n = 13, emergency cases n = 8) underwent HH with BSM augmentation. Indications in elective and emergency cases were paraesophageal (Type II-IV) HH in 83%, and large Type I HH in 4%. There was no perioperative mortality, and overall (Clavien-Dindo ≥ 2) and severe (Clavien-Dindo ≥ 3b) postoperative morbidity was 15% and 3%, respectively. An outcome without postoperative complications was achieved in 85% of cases (elective primary surgery 88%, redo cases 100%, emergencies cases 25%). After a median (IQR) postoperative follow-up of 12 months, 69 patients (74%) were asymptomatic, 15 (16%) reported improvement, and 9 (10%) had clinical failure, of which 2 patients (2%) required revisional surgery. CONCLUSION: Our data suggest that HH repair with BSM augmentation is feasible and safe with low perioperative morbidity and acceptable postoperative failure rates at early to mid-term follow-up. BSM may be a useful alternative to non-resorbable materials in HH surgery.

AIMS: There is considerable controversy regarding optimal management of patients with paraesophageal hiatus hernia (pHH). This survey aims at identifying recommended strategies for work-up, surgical therapy, and postoperative follow-up using Delphi methodology. METHODS: We conducted a 2-round, 33-question, web-based Delphi survey on perioperative management (preoperative work-up, surgical procedure and follow-up) of non-revisional, elective pHH among European surgeons with expertise in upper-GI. Responses were graded on a 5-point Likert scale and analyzed using descriptive statistics. Items from the questionnaire were defined as "recommended" or "discouraged" if positive or negative concordance among participants was > 75%. Items with lower concordance levels were labelled "acceptable" (neither recommended nor discouraged). RESULTS: Seventy-two surgeons with a median (IQR) experience of 23 (14-30) years from 17 European countries participated (response rate 60%). The annual median (IQR) individual and institutional caseload was 25 (15-36) and 40 (28-60) pHH-surgeries, respectively. After Delphi round 2, "recommended" strategies were defined for preoperative work-up (endoscopy), indication for surgery (typical symptoms and/or chronic anemia), surgical dissection (hernia sac dissection and resection, preservation of the vagal nerves, crural fascia and pleura, resection of retrocardial lipoma) and reconstruction (posterior crurorrhaphy with single stitches, lower esophageal sphincter augmentation (Nissen or Toupet), and postoperative follow-up (contrast radiography). In addition, we identified "discouraged" strategies for preoperative work-up (endosonography), and surgical reconstruction (crurorrhaphy with running sutures, tension-free hiatus repair with mesh only). In contrast, many items from the questionnaire including most details of mesh augmentation (indication, material, shape, placement, and fixation technique) were "acceptable". CONCLUSIONS: This multinational European Delphi survey represents the first expert-led process to identify recommended strategies for the management of pHH. Our work may be useful in clinical practice to guide the diagnostic process, increase procedural consistency and standardization, and to foster collaborative research.

BACKGROUND: Video-based assessment by experts may structurally measure surgical performance using procedure-specific competency assessment tools (CATs). A CAT for minimally invasive esophagectomy (MIE-CAT) was developed and validated previously. However, surgeon's time is scarce and video assessment is time-consuming and labor intensive. This study investigated non-procedure-specific assessment of MIE video clips by MIE experts and crowdsourcing, collective surgical performance evaluation by anonymous and untrained laypeople, to assist procedure-specific expert review. METHODS: Two surgical performance scoring frameworks were used to assess eight MIE videos. First, global performance was assessed with the non-procedure-specific Global Operative Assessment of Laparoscopic Skills (GOALS) of 64 procedural phase-based video clips < 10 min. Each clip was assessed by two MIE experts and > 30 crowd workers. Second, the same experts assessed procedure-specific performance with the MIE-CAT of the corresponding full-length video. Reliability and convergent validity of GOALS for MIE were investigated using hypothesis testing with correlations (experience, blood loss, operative time, and MIE-CAT). RESULTS: Less than 75% of hypothesized correlations between GOALS scores and experience of the surgical team (r < 0.3), blood loss (r = - 0.82 to 0.02), operative time (r = - 0.42 to 0.07), and the MIE-CAT scores (r = - 0.04 to 0.76) were met for both crowd workers and experts. Interestingly, experts' GOALS and MIE-CAT scores correlated strongly (r = 0.40 to 0.79), while crowd workers' GOALS and experts' MIE-CAT scores correlations were weak (r = - 0.04 to 0.49). Expert and crowd worker GOALS scores correlated poorly (ICC ≤ 0.42). CONCLUSION: GOALS assessments by crowd workers lacked convergent validity and showed poor reliability. It is likely that MIE is technically too difficult to assess for laypeople. Convergent validity of GOALS assessments by experts could also not be established. GOALS might not be comprehensive enough to assess detailed MIE performance. However, expert's GOALS and MIE-CAT scores strongly correlated indicating video clip (instead of full-length video) assessments could be useful to shorten assessment time.

BACKGROUND: Symptomatic and large hiatal hernia (HH) is a common disorder requiring surgical management. However, there is a lack of systematic, evidence-based recommendations summarizing recent reviews on surgical treatment of symptomatic HH. Therefore, this systematic review aimed to create evidence mapping on the key technical issues of HH repair based on the highest available evidence. METHODS: A systematic review identified studies on eight key issues of large symptomatic HH repair. The literature was screened for the highest level of evidence (LE from level 1 to 5) according to the Oxford Center for evidence-based medicine's scale. For each topic, only studies of the highest available level of evidence were considered. RESULTS: Out of the 28.783 studies matching the keyword algorithm, 47 were considered. The following recommendations could be deduced: minimally invasive surgery is the recommended approach (LE 1a); a complete hernia sac dissection should be considered (LE 3b); extensive division of short gastric vessels cannot be recommended; however, limited dissection of the most upper vessels may be helpful for a floppy fundoplication (LE 1a); vagus nerve should be preserved (LE 3b); a dorso-ventral cruroplasty is recommended (LE 1b); routine fundoplication should be considered to prevent postoperative gastroesophageal reflux (LE 2b); posterior partial fundoplication should be favored over other forms of fundoplication (LE 1a); mesh augmentation is indicated in large HH with paraesophageal involvement (LE 1a). CONCLUSION: The current evidence mapping is a reasonable instrument based on the best evidence available to guide surgeons in determining optimal symptomatic and large HH repair.

OBJECTIVE: To explore the prospects of academic e-learning by evaluating our long-standing internet-based surgical learning program and to assess the impact of training on the presentation skills of our residents. The eventual goal is to search whether such models could be further developed by the European Surgical Association (ESA). BACKGROUND: E-learning has become a major educational trend particularly during the COVID-19 pandemic. For more than a decade, our academic tertiary center has released weekly video-lectures covering the entire abdominal-surgical curriculum for residents. All lessons were prepared under the supervision of specialized experts and recorded and edited by a professional film team before being released on a dedicated YouTube channel ( https://www.usz.ch/surgical-resident-lectures ). METHODS: To date, our channel includes 120 presentations with more than 619,000 views. We conducted a survey among online users with a medical background and tested the benefits and potential for improvements of local stakeholders to collect individual reviews. RESULTS: A total of 708 users from 106 countries participated in the survey. Continuing medical education (49%), specific questions (38%), and exam preparation (33%) were the main motivations for video viewing. The preferred topics were current guidelines (69%), latest research topics (59%), and complex surgical conditions (52%). Ninety-four percent of our local audience reported a positive learning experience. CONCLUSION: E-learning can improve local academic training and promote the global visibility of strong academic centers. Providing free and unrestricted expertise via social media is a novel and groundbreaking opportunity that fills a global education gap by dissemination of surgical education on an unprecedented scale. Expert associations such as the ESA may adopt similar formats and foster their perception as true beacons of knowledge.

OBJECTIVE: To define a standardized methodology for establishing benchmarks for relevant outcomes in surgery. SUMMARY BACKGROUND DATA: Benchmarking is an established tool to improve quality in industry and economics, and is emerging in assessing outcome values in surgery. Despite a recent 10-step approach to identify such benchmark values, a standardized and more widely agreed-on approach is still lacking. METHODS: A multinational web-based Delphi survey with a focus on methodological requirements for establishing benchmarks for surgical outcomes was performed. Participants were selected among internationally renowned specialists in abdominal, vascular, and thoracic surgery. Consensus was defined as ≥70% agreement and results were used to develop a checklist to establish benchmarks in surgery. RESULTS: Forty-one surgical opinion leaders from 19 countries and 5 continents were involved. Experts' response rates were 98% and 80% in rounds 1 and 2, respectively. Upon completion of the final Delphi round, consensus was successfully achieved for 26 of 36 items covering the following areas: center eligibility, validation of databases, patient cohort selection, procedure selection, duration of follow-up, statistical analysis, and publication requirements regarding center-specific outcomes. CONCLUSIONS: This multinational Delphi survey represents the first expert-led process for developing a standardized approach for establishing benchmarks for relevant outcome measures in surgery. The provided consensual checklist customizes the methodology of outcome reporting in surgery and thus improves reproducibility and comparability of data and should ultimately serve to improve quality of care.

OBJECTIVE: To describe the pooled learning curves of Ivor Lewis totally minimally invasive esophagectomy (TMIE) in hospitals stratified by predefined hospital- and surgeon-related factors. BACKGROUND: Ivor Lewis (TMIE is known to have a long learning curve which is associated with considerable learning associated morbidity. It is unknown whether hospital and surgeon characteristics are associated with more efficient learning. METHODS: A retrospective analysis of prospectively collected data of consecutive Ivor Lewis TMIE patients in 14 European hospitals was performed. Outcome parameters used as proxy for efficient learning were learning curve length, learning associated morbidity, and the plateau level regarding anastomotic leakage and textbook outcome. Pooled incidences were plotted for the factor-based subgroups using generalized additive models and 2-phase models. Casemix predicted outcomes were plotted and compared with observed outcomes. The investigated factors included annual volume, TMIE experience, clinic visits, courses and fellowships followed, and proctor supervision. RESULTS: This study included 2121 patients. The length of the learning curve was shorter for centers with an annual volume >50 compared to centers with an annual volume <50. Analysis with an annual volume cut-off of 30 cases showed similar but less pronounced results. No outcomes suggesting more efficient learning were found for longer experience as consultant, visiting an expert clinic, completing a minimally invasive esophagectomy fellowship or implementation under proctor supervision. CONCLUSIONS: More efficient learning was observed in centers with higher annual volume. Visiting an expert clinic, completing a fellowship, or implementation under a proctor's supervision were not associated with more efficient learning.

BACKGROUND: Endoscopic vacuum therapy (EVT) has emerged as a novel treatment option for upper gastrointestinal wall defects. The basic principle of action of EVT entails evacuation of secretions, removal of wound debris, and containment of the defect. Furthermore, there is increasing evidence that EVT reduces interstitial edema, increases oxygen saturation, and promotes tissue granulation and microcirculation. Various devices, such as macroporous polyurethane sponge systems or open-pore film drains, have been developed for specific indications. Depending on the individual situation, EVT devices can be placed in- or outside the intestinal lumen, as a stand-alone procedure, or in combination with surgical, radiological, and other endoscopic interventions. PURPOSE: The aim of this narrative review is to describe the current spectrum of EVT in the upper gastrointestinal tract and to assess and summarize the related scientific literature. CONCLUSIONS: There is growing evidence that the efficacy of EVT for upper GI leakages exceeds that of other interventional treatment modalities such as self-expanding metal stents, clips, or simple drainages. Owing to the promising results and the excellent risk profile, EVT has become the therapy of choice for perforations and anastomotic leakages of the upper gastrointestinal tract in many centers of expertise. In addition, recent clinical research suggests that preemptive use of EVT after high-risk upper gastrointestinal resections may play an important role in reducing postoperative morbidity.

OBJECTIVE: Preemptive endoluminal vacuum therapy (pEVT) is a novel concept to reduce postoperative morbidity and has the potential to disrupt current treatment paradigms for patients undergoing esophagectomy. SUMMARY OF BACKGROUND DATA: Endoluminal vacuum therapy is an accepted treatment for AL after esophagectomy. METHODS: Retrospective analysis of patients undergoing minimally invasive Ivor Lewis esophagectomy with pEVT between 11/2017 and 10/2020. The sponge was removed endoscopically after 4-6âdays, and anastomosis and gastric conduit were assessed according to a novel endoscopic grading system. Further management was customized according to endoscopic appearance and clinical course. Endpoints were postoperative morbidity and AL rate, defined according to the Clavien-Dindo (CD) and International Esodata Study Group classifications. RESULTS: PEVT was performed in 67 consecutive patients, 57 (85%) were high-risk patients with an ASA score >2, WHO/ECOG score >1, age >65âyears, or BMI >29âkg/m2. Thirty patients experienced textbook outcome, and overall minor (≤CD IIIa) and major (≥CD IIIb) morbidity was 40.3% and 14.9% respectively. 30-day-mortality was 0%. Forty-nine patients (73%) had uneventful anastomotic healing after pEVT without further endoscopic treatment. The remaining 18 patients (27%) underwent prolonged EVT with uneventful anastomotic healing in 13 patients (19%), contained AL in 4 patients (6%), and 1 uncontained leakage (1.5%) in a case with proximal gastric conduit necrosis, resulting in an overall AL rate of 7.5%. CONCLUSIONS: PEVT is an innovative and safe procedure with a promising potential to reduce postoperative morbidity after minimally invasive Ivor Lewis esophagectomy and may be particularly valuable in highly comorbid cases.

BACKGROUND: Esophagectomy is a technically challenging procedure, associated with significant morbidity. The introduction of minimally invasive esophagectomy (MIE) has reduced postoperative morbidity. OBJECTIVE: Although the short-term effect on complications is increasingly being recognized, the impact on long-term survival remains unclear. This study aims to investigate the association between postoperative complications following MIE and long-term survival. METHODS: Data were collected from the EsoBenchmark Collaborative composed by 13 high-volume, expert centers routinely performing MIE. Patients operated between June 1, 2011 and May 31, 2016 were included. Complications were graded using the Clavien-Dindo (CD) classification. To correct for short-term effects of postoperative complications on mortality, patients who died within 90 days postoperative were excluded. Primary endpoint was 5-year overall survival. RESULTS: A total of 915 patients were included with a mean follow-up time of 30.8 months (standard deviation 17.9). Complications occurred in 542 patients (59.2%) of which 50.2% had a CD grade ≥III complication [ie, (re)intervention, organ dysfunction, or death]. The incidence of anastomotic leakage (AL) was 135 of 915 patients (14.8%) of which 84 patients were classified as a CD grade ≥III. Multivariable analysis showed a significantly deteriorated long-term survival in all patients with AL [hazard ratio (HR) 1.68, 95% confidence interval (CI) 1.25-2.24]. This inverse relation was most distinct when AL was scored as a CD grade ≥III (HR 1.83, 95% CI 1.30-2.58). For all other complications, no significant association with long-term survival was found. CONCLUSION: The occurrence and severity of AL, but not overall complications, after MIE negatively affect long-term survival of esophageal cancer patients.

BACKGROUND: Surgery is the cornerstone of esophageal cancer treatment but remains burdened with significant postoperative changes of gastrointestinal function and quality of life. PURPOSE: The aim of this narrative review is to assess and summarize the current knowledge on postoperative functional syndromes and quality of life after esophagectomy for cancer, and to provide orientation for the reader in the challenging field of functional aftercare. CONCLUSIONS: Post-esophagectomy syndromes include various conditions such as dysphagia, reflux, delayed gastric emptying, dumping syndrome, weight loss, and chronic diarrhea. Clinical pictures and individual expressions are highly variable and may be extremely distressing for those affected. Therefore, in addition to a mostly well-coordinated oncological follow-up, we strongly emphasize the need for regular monitoring of physical well-being and gastrointestinal function. The prerequisite for an effective functional aftercare covering the whole spectrum of postoperative syndromes is a comprehensive knowledge of the pathophysiological background. As functional conditions often require a complex diagnostic workup and long-term therapy, close interdisciplinary cooperation with radiologists, gastroenterologists, oncologists, and specialized nutritional counseling is imperative for successful management.

BACKGROUND: In recent years, minimally invasive Ivor Lewis (IL) esophagectomy with high intrathoracic anastomosis has emerged as surgical standard of care for esophageal cancer in expert centers. Alongside this process, many divergent technical aspects of this procedure have been devised in different centers. This study aims at achieving international consensus on the surgical steps of IL reconstruction using Delphi methodology. METHODS: The expert panel consisted of specialized esophageal surgeons from 8 European countries. During a two-round Delphi process, a detailed analysis and consensus on key steps of intrathoracic gastric tube reconstruction (IL esophagectomy) was performed. RESULTS: Response rates in Delphi rounds 1 and 2 were 100% (22 of 22 experts) and 83.3% (20 of 24 experts), respectively. Three essential technical areas of intrathoracic gastric tube reconstruction were identified: first, vascularization of the gastric conduit, second, gastric mobilization, tube formation and pull-up, and third, anastomotic technique. In addition, 3 main techniques for minimally invasive intrathoracic anastomosis are currently practiced: (i) end-to-side circular stapled, (ii) end-to-side double stapling, and (iii) side-to-side linear stapled technique. The step-by-step procedural analysis unveiled common approaches but also different expert practice. CONCLUSION: This precise technical description may serve as a clinical guideline for intrathoracic reconstruction after esophagectomy. In addition, the results may aid to harmonize the technical evolution of this complex surgical procedure and thereby facilitate surgical training.

BACKGROUND: Surgery remains the cornerstone of esophageal cancer treatment but is burdened with high procedure-related morbidity. Anastomotic leakage as the most important surgical complication after esophagectomy is a key indicator for quality in surgical outcome research. PURPOSE: The aim of this narrative review is to assess and summarize the current knowledge on prevention of anastomotic leakage after esophagectomy and to provide orientation for the reader in this challenging field of surgery. CONCLUSIONS: There are various strategies to reduce postoperative morbidity and to prevent anastomotic leakage after esophagectomy, including adequate patient selection and preparation, and many technical-surgical and anesthesiological details. The scientific evidence regarding those strategies is highly heterogeneous, ranging from expert's recommendations to randomized controlled trials. This review is intended to serve as an empirical guideline to improve the clinical management of patients undergoing esophagectomy with a special focus on anastomotic leakage prevention.

OBJECTIVE: The aim of this study was to describe anastomotic techniques used for total minimally invasive transthoracic esophagectomy (ttMIE) and to analyze the associated morbidity. BACKGROUND: ttMIE faces increasing application in surgical treatment of esophageal cancer. For esophagogastric reconstruction, different anastomotic techniques are currently used, but their effect on postoperative anastomotic leakage and morbidity has not been investigated. PATIENTS AND METHODS: Patients were selected from a basic dataset, collected during a 5-year period from 13 international surgical high-volume centers. Endpoints were anastomotic leakage rate and postoperative morbidity in correlation to anastomotic techniques, measured by the Clavien-Dindo classification and the Comprehensive Complication Index (CCI). RESULTS: Five anastomotic techniques were identified in 966 patients after ttMIE: intrathoracic end-to-side circular-stapled technique in 427 patients (double-stapling n = 90, purse-string n = 337), intrathoracic (n = 109) or cervical (n = 255) side-to-side linear-stapled, and cervical end-to-side hand-sewn (n = 175). Leakage rates were similar in intrathoracic and cervical anastomoses (15.9% vs 17.2%, P = 0.601), but overall complications (56.7%% vs 63.7%, P = 0.029) and median 90-day CCI {21 [interquartile range (IQR) 0-36] vs 29 [IQR 0-40], P = 0.019} favored intrathoracic reconstructions. Leakage rates after intrathoracic end-to-side double-stapling (23.3%) and cervical end-to-side hand-sewn (25.1%) techniques were significantly higher compared with intrathoracic side-to-side linear (15.6%), end-to-side purse-string (13.9%), and cervical side-to-side linear-stapled esophagogastrostomies (11.8%) (P < 0.001). Multivariable analysis confirmed anastomotic technique as independent predictor of leakage after ttMIE. CONCLUSION: Results of this analysis present the current status of the technical evolution of ttMIE with anastomotic leakage as predominant surgical complication. However, technique-related morbidity requires cautious interpretation considering the long learning curve of this complex surgical procedure.
