What are the short- and long-term abdominal consequences of an omentectomy? A systematic review. J Surg Oncol 2024. [PMID: 38606519 DOI: 10.1002/jso.27640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Accepted: 04/01/2024] [Indexed: 04/13/2024]
Abstract
This review provides an overview regarding the abdominal effects of an omentectomy, with or without extra-peritoneal reconstructions. In general, reported complication rates were low. Short-term complications involved ileus, bowel stenosis, abdominal abscess and sepsis (range 0.0%-23%). Donor-site hernia was mainly reported as long-term complication (up to 32%) and negligible gastrointestinal complications were observed. However, the level of evidence and methodological quality are quite low with a maximum of 8.5 years follow-up.

Prognostic value of Mandard score and nodal status for recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma. Br J Surg 2024; 111:znae034. [PMID: 38387083 PMCID: PMC10883709 DOI: 10.1093/bjs/znae034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 01/30/2024] [Accepted: 01/31/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND This study evaluated the association of pathological tumour response (tumour regression grade, TRG) and a novel scoring system, combining both TRG and nodal status (TRG-ypN score; TRG1-ypN0, TRG>1-ypN0, TRG1-ypN+ and TRG>1-ypN+), with recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma. METHODS This Dutch nationwide cohort study included patients treated with neoadjuvant chemoradiotherapy followed by oesophagectomy for distal oesophageal or gastro-oesophageal junctional adenocarcinoma between 2007 and 2016. The primary endpoint was the association of Mandard score and TRG-ypN score with recurrence patterns (rate, location, and time to recurrence). The secondary endpoint was overall survival. RESULTS Among 2746 inclusions, recurrence rates increased with higher Mandard scores (TRG1 30.6%, TRG2 44.9%, TRG3 52.9%, TRG4 61.4%, TRG5 58.2%; P < 0.001). Among patients with recurrent disease, the distribution (locoregional versus distant) was the same for the different TRG groups. Patients with TRG1 developed more brain recurrences (17.7 versus 9.8%; P = 0.001) and had a longer mean overall survival (44 versus 35 months; P < 0.001) than those with TRG>1. The TRG>1-ypN+ group had the highest recurrence rate (64.9%) and worst overall survival (mean 27 months). Compared with the TRG>1-ypN0 group, patients with TRG1-ypN+ had a higher risk of recurrence (51.9 versus 39.6%; P < 0.001) and worse mean overall survival (33 versus 41 months; P < 0.001). CONCLUSION Improved tumour response to neoadjuvant therapy was associated with lower recurrence rates and higher overall survival rates. Among patients with recurrent disease, TRG1 was associated with a higher incidence of brain recurrence than TRG>1. Residual nodal disease influenced prognosis more negatively than residual disease at the primary tumour site.

Patterns of recurrent disease after neoadjuvant chemoradiotherapy and esophageal cancer surgery with curative intent in a tertiary referral center. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:106947. [PMID: 37355392 DOI: 10.1016/j.ejso.2023.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 11/29/2022] [Accepted: 05/31/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND Recurrence is frequently observed after esophageal cancer surgery, with dismal post-recurrence survival. Neoadjuvant chemoradiotherapy followed by esophagectomy is the gold standard for resectable esophageal tumors in the Netherlands. This study investigated the recurrence patterns and survival after multimodal therapy. METHODS This retrospective cohort study included patients with recurrent disease after neoadjuvant chemoradiotherapy followed by esophagectomy for an esophageal adenocarcinoma in the Amsterdam UMC between 01 and 01-2010 and 31-12-2018. Post-recurrence treatment and survival of patients were investigated and grouped by recurrence site (loco-regional, distant, or combined loco-regional and distant). RESULTS In total, 278 of 618 patients (45.0%) developed recurrent disease after a median of 49 weeks. Thirty-one patients had loco-regional (11.2%), 145 distant (52.2%), and 101 combined loco-regional and distant recurrences (36.3%). Post-recurrence survival was superior for patients with loco-regional recurrences (33 weeks, 95%CI 7.3-58.7) compared to distant (12 weeks, 95%CI 6.9-17.1) or combined loco-regional and distant recurrent disease (18 weeks, 95%CI 9.3-26.7). Patients with loco-regional recurrences treated with curative intent had the longest survival (87 weeks, 95%CI 6.9-167.4). CONCLUSION Recurrent disease after potentially curative treatment for esophageal cancer was most frequently located distantly, with dismal prognosis. A subgroup of patients with loco-regional recurrence was treated with curative intent and had prolonged survival. These patients may benefit from intensive surveillance protocols, and more research is needed to identify these patients.

Abstract
OBJECTIVE This study evaluated the nationwide trends in care and accompanied postoperative outcomes for patients with distal esophageal and gastro-esophageal junction cancer. SUMMARY OF BACKGROUND DATA The introduction of transthoracic esophagectomy, minimally invasive surgery, and neo-adjuvant chemo(radio)therapy changed care for patients with esophageal cancer. METHODS Patients after elective transthoracic and transhiatal esophagectomy for distal esophageal or gastroesophageal junction carcinoma in the Netherlands between 2007-2016 were included. The primary aim was to evaluate trends in both care and postoperative outcomes for the included patients. Additionally, postoperative outcomes after transthoracic and tran-shiatal esophagectomy were compared, stratified by time periods. RESULTS Among 4712 patients included, 74% had distal esophageal tumors and 87% had adenocarcinomas. Between 2007 and 2016, the proportion of transthoracic esophagectomy increased from 41% to 81%, and neo-adjuvant treatment and minimally invasive esophagectomy increased from 31% to 96%, and from 7% to 80%, respectively. Over this 10-year period, postoperative outcomes improved: postoperative morbidity decreased from 66.6% to 61.8% ( P = 0.001), R0 resection rate increased from 90.0% to 96.5% (P <0.001), median lymph node harvest increased from 15 to 19 ( P <0.001), and median survival increased from 35 to 41 months ( P = 0.027). CONCLUSION In this nationwide cohort, a transition towards more neo-adju-vant treatment, transthoracic esophagectomy and minimally invasive surgery was observed over a 10-year period, accompanied by decreased postoperative morbidity, improved surgical radicality and lymph node harvest, and improved survival.

Abstract
INTRODUCTION Implant loss following breast reconstruction is a devastating complication, which should be prevented as much as possible. This study aimed to validate a previously developed multicenter risk model for implant loss after implant-based breast reconstructions, using national data from the Dutch Breast Implant Registry (DBIR). METHODS The validation cohort consisted of patients who underwent a mastectomy followed by either a direct-to-implant (DTI) or two-stage breast reconstruction between September 2017 and January 2021 registered in the DBIR. Reconstructions with an autologous adjunctive and patients with missing data on the risk factors extracted from the multicenter risk model (obesity, smoking, nipple preserving procedure, DTI reconstruction) were excluded. The primary outcome was implant loss. The predicted probability of implant loss was calculated using beta regression coefficients extracted from the multicenter risk model and compared to the observed probability. RESULTS The validation cohort consisted of 3769 reconstructions and implant loss occurred after 307 reconstructions (8.1%). Although the observed implant loss rate increased when the risk factors accumulated, the predicted and observed probabilities of implant loss did not match. Of the four risk factors in the multicenter risk model, only obesity and smoking were significantly associated to implant loss. CONCLUSION The multicenter risk model could not be validated using nationwide data of the DBIR and is therefore not accurate in Dutch practice. In the future, the risk model should be improved by including other factors to provide a validated tool for the preoperative risk assessment of implant loss.

Short-term outcome for high-risk patients after esophagectomy. Dis Esophagus 2022; 36:6611914. [PMID: 35724560 PMCID: PMC9817823 DOI: 10.1093/dote/doac028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 03/29/2022] [Accepted: 02/14/2022] [Indexed: 01/11/2023]
Abstract
Transthoracic esophagectomy (TTE) for esophageal cancer facilitates mediastinal dissection; however, it has a significant impact on cardiopulmonary status. High-risk patients may therefore be better candidates for transhiatal esophagectomy (THE) in order to prevent serious complications. This study addressed short-term outcome following TTE and THE in patients that are considered to have a higher risk of surgery-related morbidity. This population-based study included patients who underwent a curative esophagectomy between 2011 and 2018, registered in the Dutch Upper GI Cancer Audit. The Charlson comorbidity index was used to assign patients to a low-risk (score ≤ 1) and high-risk group (score ≥ 2). Propensity score matching was applied to produce comparable groups between high-risk patients receiving TTE and THE. Primary endpoint was mortality (in-hospital/30-day mortality), secondary endpoints included morbidity and oncological outcomes. Additionally, a matched subgroup analysis was performed, including only cervical reconstructions. Of 5,438 patients, 945 and 431 high-risk patients underwent TTE and THE, respectively. After propensity score matching, mortality (6.3 vs 3.3%, P = 0.050), overall morbidity, Clavien-Dindo ≥ 3 complications, pulmonary complications, cardiac complications and re-interventions were significantly more observed after TTE compared to THE. A significantly higher mortality after TTE with a cervical reconstruction was found compared to THE (7.0 vs. 2.2%, P = 0.020). Patients with a high Charlson comorbidity index predispose for a complicated postoperative course after esophagectomy, this was more outspoken after TTE compared to THE. In daily practice, these outcomes should be balanced with the lower lymph node yield, but comparable positive node count and radicality after THE.

Esophageal microbiota composition and outcome of esophageal cancer treatment: a systematic review. Dis Esophagus 2021; 35:6425236. [PMID: 34761269 PMCID: PMC9376764 DOI: 10.1093/dote/doab076] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 09/24/2021] [Accepted: 10/10/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND The role of esophageal microbiota in esophageal cancer treatment is gaining renewed interest, largely driven by novel DNA-based microbiota analysis techniques. The aim of this systematic review is to provide an overview of current literature on the possible association between esophageal microbiota and outcome of esophageal cancer treatment, including tumor response to (neo)adjuvant chemo(radio)therapy, short-term surgery-related complications, and long-term oncological outcome. METHODS A systematic review of literature was performed, bibliographic databases were searched and relevant articles were selected by two independent researchers. The Newcastle-Ottawa scale was used to estimate the quality of included studies. RESULTS The search yielded 1303 articles, after selection and cross-referencing, five articles were included for qualitative synthesis and four studies were considered of good quality. Two articles addressed tumor response to neoadjuvant chemotherapy and described a correlation between high intratumoral Fusobacterium nucleatum levels and a poor response. One study assessed surgery-related complications, in which no direct association between esophageal microbiota and occurrence of complications was observed. Three studies described a correlation between shortened survival and high levels of intratumoral F. nucleatum, a low abundance of Proteobacteria and high abundances of Prevotella and Streptococcus species. CONCLUSIONS Current evidence points towards an association between esophageal microbiota and outcome of esophageal cancer treatment and justifies further research. Whether screening of the individual esophageal microbiota can be used to identify and select patients with a predisposition for adverse outcome needs to be further investigated. This could lead to the development of microbiota-based interventions to optimize esophageal microbiota composition, thereby improving outcome of patients with esophageal cancer.

Abstract
Purpose The number of bariatric procedures has increased exponentially over the last 20 years. On the background of ever-increasing incidence of esophageal malignancies, the altered anatomy after bariatric surgery poses challenges in treatment of these cancers. In this study, an epidemiological estimate is presented for the future magnitude of this problem and treatment options are described in a retrospective multicenter cohort. Methods The number of bariatric procedures, esophageal cancer incidence, and mortality rates of the general population were used for epidemiological estimates. A retrospective multicenter cohort was composed; patients were treated in three large oncological centers with a high upper gastrointestinal cancer caseload. Consecutive patients with preceding bariatric surgery who developed esophageal cancer between 2014 and 2019 were included. Results Approximately 3200 out of 6.4 million post bariatric surgery patients are estimated to have developed esophageal cancer between 1998 and 2018 worldwide. In a multicenter cohort, 15 patients with esophageal cancer or Barrett’s esophagus and preceding bariatric surgery were identified. The majority of patients had a history of Roux-en-Y gastric bypass (46.7%) and had an adenocarcinoma of the distal esophagus (60%). Seven patients received curative surgical treatment, five of whom are still alive at last follow-up (median follow-up 2 years, no loss to follow-up). Conclusion Based on worldwide data, esophageal cancer development following bariatric surgery has increased over the past decades. Treatment of patients with esophageal cancer after bariatric surgery is challenging and requires a highly individualized approach in which optimal treatment and anatomical limitations are carefully balanced.

Abstract
BACKGROUND Infectious complications are frequently encountered after abdominal surgery. Early recognition, diagnosis, and subsequent timely treatment is the single most important denominator of postoperative outcome. This study prospectively addressed the predictive value of routine assessment of C-reactive protein levels as an early marker for infectious complications after major abdominal surgery. METHODS Consecutive patients undergoing major abdominal surgery between November 2015 and November 2019 were prospectively enrolled. Routine C-reactive protein measurements were implemented on postoperative days 3, 4, and 5, and additional computed tomography examinations were performed on demand. The primary endpoint was the occurrence of Clavien-Dindo grade III or higher infectious complications. RESULTS Of 350 patients, 71 (20.3%) experienced a major infectious complication, and median time to diagnosis was 7 days. C-reactive protein levels were significantly higher in patients with major infectious complications compared to minor or no infectious complications. The optimal cut-off was calculated for each postoperative day, being 175 mg/L on day 3, 130 mg/L on day 4, and 144 mg/L on day 5, and corresponding sensitivities, specificities, and positive and negative predictive values were over 80%, 65%, 40%, and 92% respectively. Alternative safe discharge cut-offs were calculated at 105 mg/L, 71 mg/L and 63 mg/L on days 3, 4, and 5, respectively, each having a negative predictive value of over 97%. CONCLUSION The C-reactive protein cut-offs provided in this study can be used as a discharge criterion or to select patients that might require an invasive intervention due to infectious complications. These diagnostic criteria can easily be implemented in daily surgical practice.

Abstract
Background CT imaging is the primary diagnostic approach to assess the integrity of the intrathoracic anastomosis following Ivor Lewis esophagectomy. In the postoperative setting interpretation of CT findings, such as air and fluid collections, may be challenging. Establishment of a scoring system that incorporates CT findings to diagnose anastomotic leakage could assist radiologists and surgeons in the postoperative phase. Methods Consecutive patients who underwent a CT scan for a clinical suspicion of postoperative anastomotic leakage following Ivor Lewis esophagectomy between 2010 and 2016 in two medical centers were retrospectively included. Scans were excluded when oral contrast was not (correctly) administered. Acquired images were randomized and independently assessed by two experienced gastrointestinal radiologists, blinded for clinical information. For this study anastomotic leakage was defined as a visible defect during endoscopy or thoracotomy. Results A total of 80 patients had 101 CT scans, resulting in 32 scans with a confirmed anastomotic leak (25 patients). After multivariable backward stepwise logistic regression, a practical 5-point scoring system was developed, which included the following CT findings: presence of extraluminal oral contrast, air collection at the anastomotic site, fluid collection at the anastomotic site, pneumothorax and loculated pleural effusion. Patients with a score of ≥3 were considered at high risk for anastomotic leakage (positive predictive value: 83.3%), patients with scores <3 were considered at low risk for anastomotic leakage (negative predictive value: 84.4%). The scoring system showed a superior diagnostic performance compared to the original CT report and blinded interpretation of two radiologists. Conclusions Our CT-based practical scoring system enables a standardized approach in CT assessment and could facilitate early recognition of anastomotic leakage in patients after Ivor Lewis esophagectomy.

Abstract
BACKGROUND Anastomotic leakage (AL) remains a severe complication following colorectal surgery, having a negative impact on both short- and long-term outcomes. Since timely detection could enable early intervention, there is a need for the development of novel and accurate, preferably, non-invasive markers. The aim of this study was to investigate whether urinary intestinal fatty acid binding protein (I-FABP) could serve as such a marker. METHODS This prospective multicenter cross-sectional phase two diagnostic study was conducted at four centers in the Netherlands between March 2015 and November 2016. Urine samples of 15 patients with confirmed colorectal AL and 19 patients without colorectal AL on postoperative day 3 were included. Urinary I-FABP levels were determined using enzyme-linked immunosorbent assays and adjusted for urinary creatinine to compensate for renal dysfunction. RESULTS Urinary I-FABP levels were significantly elevated in patients with confirmed AL compared to patients without AL on postoperative day 3 (median: 2.570 ng/ml vs 0.809 ng/ml, p = 0.006). The area under the receiver operating characteristics curve (AUROC) was 0.775, yielding a sensitivity of 80% and specificity of 74% at the optimal cutoff point (> 1.589 ng/ml). This difference remained significant after calculation of I-FABP/creatinine ratios (median: 0.564 ng/µmol vs. 0.158 ng/µmol, p = 0.040), with an AUROC of 0.709, sensitivity of 60% and specificity of 90% at the optimal cutoff point (> 0.469 ng/µmol). CONCLUSIONS Levels of urinary I-FABP and urinary I-FABP/creatinine were significantly elevated in patients with confirmed AL following colorectal surgery, suggesting their potential as a non-invasive biomarker for colorectal anastomotic leakage.

Abstract
AIM Inflammatory markers such as serum C-reactive protein (CRP) are used as routine markers to detect anastomotic leakage following colorectal surgery. However, CRP is characterized by a relatively low predictive value, emphasizing the need for the development of novel diagnostic approaches. Volatile organic compounds (VOCs) are gaseous metabolic products deriving from all conceivable bodily excrements and reflect (alterations in) the patient's physical status. Therefore, VOCs are increasingly considered as potential non-invasive diagnostic biomarkers. The aim of this study was to assess the diagnostic accuracy of urinary VOCs for colorectal anastomotic leakage. METHODS In this explorative multicentre study, urinary VOC profiles of 22 patients with confirmed anastomotic leakage and 27 uneventful control patients following colorectal surgery were analysed by field asymmetric ion mobility spectrometry (FAIMS). RESULTS Urinary VOCs of patients with anastomotic leakage could be distinguished from those of control patients with high accuracy: area under the receiver operating characteristics curve 0.91 (95% CI 0.81-1.00, P < 0.001), sensitivity 86% and specificity 93%. Serum CRP was significantly increased in patients with a confirmed anastomotic leak but with lower diagnostic accuracy compared to VOC analysis (area under the receiver operating characteristics curve 0.82, 95% CI 0.68-0.95, P < 0.001). Combining VOCs and CRP did not result in a significant improvement of the diagnostic performance compared to VOCs alone. CONCLUSION Analysis by FAIMS allowed for discrimination between urinary VOC profiles of patients with a confirmed anastomotic leak and control patients following colorectal surgery. A superior accuracy compared to CRP and apparently high specificity was observed, underlining the potential as a non-invasive biomarker for the detection of colorectal anastomotic leakage.

Abstract
BACKGROUND Esophagectomy or pancreaticoduodenectomy is the standard surgical approach for patients with tumors of the esophagus or pancreatic head. Postoperative mortality is strongly correlated with the occurrence of anastomotic leakage (AL). Delay in diagnosis leads to delay in treatment, which ratifies the need for development of novel and accurate non-invasive diagnostic tests for detection of AL. Urinary volatile organic compounds (VOCs) reflect the metabolic status of an individual, which is associated with a systemic immunological response. The aim of this study was to determine the diagnostic accuracy of urinary VOCs to detect AL after esophagectomy or pancreaticoduodenectomy. METHODS In the present study, urinary VOCs of 63 patients after esophagectomy (n = 31) or pancreaticoduodenectomy (n = 32) were analyzed by means of field asymmetric ion mobility spectrometry. AL was defined according to international study groups. RESULTS AL was observed in 15 patients (24%). Urinary VOCs of patients with AL after pancreaticoduodenectomy could be distinguished from uncomplicated controls, area under the curve 0.85 (95% CI 0.76-0.93), sensitivity 76%, and specificity 77%. However, this was not observed following esophagectomy, area under the curve 0.51 (95% CI 0.37-0.65). CONCLUSION In our study population AL following pancreaticoduodenectomy could be discriminated from uncomplicated controls by means of urinary VOC analysis, NTC03203434.

Abstract
BACKGROUND Esophageal cancer is surgically treated by means of an esophagectomy. However, esophagectomies are associated with high morbidity rates with dehiscence of the anastomosis occurring in 19% of these procedures in the Netherlands. Application of a fibrin sealant may improve mechanical strength of the anastomosis. The aim of this study was to determine the technical feasibility of the application of an autologous fibrin sealant by aerosolized spraying on esophageal anastomoses. METHODS This study was designed as a single-center feasibility study. Patients undergoing elective minimal invasive esophageal surgery with the creation of a thoracic or a cervical anastomosis were eligible. Fibrin sealant (Vivostat) was applied to the anastomosis intraoperatively. Feasibility was measured using a nine-item checklist, designed for intraoperative application. RESULTS In total, fifteen patients, between the ages of 43-79 y, were included in this study. One procedure scored eight out of nine points on the feasibility checklist, so application was considered as unsuccessful. The other fourteen procedures obtained a 100% score and were documented as successful procedures. Together, this led to a success rate of 93%. Grade III anastomotic leakage occurred in one of the fifteen patients (6.7%). CONCLUSIONS This study showed that application of fibrin sealant on esophageal anastomoses is technically feasible and safe. Future studies may investigate the possible protective effects of fibrin sealant application on the development of anastomotic leakage. NCT03251040.
