Abstract
BACKGROUND The COVID-19 pandemic caused disruption of regular healthcare leading to reduced hospital attendances, repurposing of surgical facilities, and cancellation of cancer screening programmes. This study aimed to determine the impact of COVID-19 on surgical care in the Netherlands. METHODS A nationwide study was conducted in collaboration with the Dutch Institute for Clinical Auditing. Eight surgical audits were expanded with items regarding alterations in scheduling and treatment plans. Data on procedures performed in 2020 were compared with those from a historical cohort (2018-2019). Endpoints included total numbers of procedures performed and altered treatment plans. Secondary endpoints included complication, readmission, and mortality rates. RESULTS Some 12 154 procedures were performed in participating hospitals in 2020, representing a decrease of 13.6 per cent compared with 2018-2019. The largest reduction (29.2 per cent) was for non-cancer procedures during the first COVID-19 wave. Surgical treatment was postponed for 9.6 per cent of patients. Alterations in surgical treatment plans were observed in 1.7 per cent. Time from diagnosis to surgery decreased (to 28 days in 2020, from 34 days in 2019 and 36 days in 2018; P < 0.001). For cancer-related procedures, duration of hospital stay decreased (5 versus 6 days; P < 0.001). Audit-specific complications, readmission, and mortality rates were unchanged, but ICU admissions decreased (16.5 versus 16.8 per cent; P < 0.001). CONCLUSION The reduction in the number of surgical operations was greatest for those without cancer. Where surgery was undertaken, it appeared to be delivered safely, with similar complication and mortality rates, fewer admissions to ICU, and a shorter hospital stay.

Abstract
Abstract
Background
Anastomotic leak (AL) is a common but severe complication after oesophagectomy. It is unknown how to determine the severity of AL objectively at diagnosis. Determining leak severity may guide treatment decisions and improve future research. This study aimed to identify leak-related prognostic factors for mortality, and to develop a Severity of oEsophageal Anastomotic Leak (SEAL) score.
Methods
This international, retrospective cohort study in 71 centres worldwide included patients with AL after oesophagectomy between 2011 and 2019. The primary endpoint was 90-day mortality. Leak-related prognostic factors were identified after adjusting for confounders and were included in multivariable logistic regression to develop the SEAL score. Four classes of leak severity (mild, moderate, severe, and critical) were defined based on the risk of 90-day mortality, and the score was validated internally.
Results
Some 1509 patients with AL were included and the 90-day mortality rate was 11.7 per cent. Twelve leak-related prognostic factors were included in the SEAL score. The score showed good calibration and discrimination (c-index 0.77, 95 per cent c.i. 0.73 to 0.81). Higher classes of leak severity graded by the SEAL score were associated with a significant increase in duration of ICU stay, healing time, Comprehensive Complication Index score, and Esophagectomy Complications Consensus Group classification.
Conclusion
The SEAL score grades leak severity into four classes by combining 12 leak-related predictors and can be used to the assess severity of AL after oesophagectomy.

Abstract
AIM Morbidity in patients with an ostomy is high. A new care pathway, including perioperative home visits by enterostomal therapists, was studied to assess whether more elaborate education and closer guidance could reduce stoma-related complications and improve quality of life (QoL), at acceptable cost. METHOD Patients requiring an ileostomy or colostomy, for any inflammatory or malignant bowel disease, were included in a 15-centre cluster-randomized 'stepped-wedge' study. Primary outcomes were stoma-related complications and QoL, measured using the Stoma-QOL, 3 months after surgery. Secondary outcomes included costs of care. RESULTS The standard pathway (SP) was followed by 113 patients and the new pathway (NP) by 105 patients. Although the overall number of stoma-related complications was similar in both groups (SP 156, NP 150), the proportion of patients experiencing one or more stoma-related complications was significantly higher in the NP (72% vs 84%, risk difference 12%; 95% CI: 0.3-23.3%). Although in the NP more patients had stoma-related complications, QoL scores were significantly better (P < 0.001). In the SP more patients required extra care at home for their ostomy than in the NP (60.6% vs 33.7%, respectively; risk difference 26.9%, 95% CI: 13.5-40.4%). Stoma revision was done more often in the SP (n = 11) than in the NP (n = 2). Total costs in the SP did not differ significantly from the NP. CONCLUSION The NP did not reduce the number of stoma-related complications but did lead to improved quality of care and life, against similar costs. Based on these results the NP, including perioperative home visits by an enterostomal therapist, can be recommended.

Abstract
Abstract
Introduction
Molecular Fluorescence Guided Surgery (MFGS) might be used for intraoperative detection of positive resection margins in breast conserving surgery (BCS) for the treatment of breast cancer. Currently, the presence of tumor positive resection margins can only be assessed ex vivo by histopathological analysis of the excised tissue, which takes up to 5 working days. The current study defined the optimal dose of the near-infrared (NIR) optical imaging tracer bevacizumab-800CW to enable intraoperative detection and image-guided pathology of tumor positive resection margins in breast cancer patients.
Methods
Molecular Fluorescence Guided Surgery during BCS was performed in subjects treated for primary breast cancer. The NIR optical imaging tracer bevacizumab-800CW targeting vascular endothelial growth factor A was administered intravenously three days prior to surgery in four escalating dose groups (4.5mg, 10mg, 25mg and 50mg). NIR fluorescent signals were detected real-time using an intraoperative fluorescence camera system (SurgVision BV). Standardized ex vivo analyses of tumor-to-normal ratios (TNR) were performed to define the optimal tracer dose using a BlackBox imaging system (SurgVision BV) for imaging fresh bread loaf slices, a NIR fluorescence flatbed scanner (Odyssey, Li-Cor) for imaging 10µm slices of formalin-fixed paraffin-embedded (FFPE) blocks, NIR Confocal Laser Endomicroscopy (CLE, Mauna Kea Technologies) and multi-diameter single fiber reflectance and single fiber fluorescence (MDSFR/SFF) spectroscopy quantification to enable correction for the influence of tissue optical properties on fluorescence in tumor and normal breast tissue.
Results
Currently, 12 subjects have been included and analyzed in four dosing groups. All tumors showed specific tracer uptake at macroscopic and microscopic level during ex vivo analyses, confirmed by histopathology. Quantification of NIR fluorescent signals showed higher TNRs by increasing doses up to 25mg. No further increase in TNR was seen in the 50mg dose group. CLE showed the feasibility of visualization of the tracer accumulation in tumor tissue compared to normal tissue at a microscopic level. MDSFR/SFF spectroscopy objectively confirmed the dose dependency up to 25mg.
Conclusion and future perspective
Intravenous administration of bevacizumab-800CW in doses up to 50mg is safe and highly tumor specific, showing a plateau of TNR at 25mg and 50mg. Further expansion of the dosing cohorts of 10mg and 25mg with additional seven patients per group will be performed to establish the optimal dose for MFGS during BCS for an upcoming phase III multicenter randomized controlled trial. By enabling MFGS during BCS the surgical treatment of primary breast cancer patients might be optimized by a reduced need for re-excision surgery and thereby reducing the risk of co-morbidity, psychological burden, poor cosmesis and healthcare costs.

Abstract
BACKGROUND In ovarian cancer, optimal cytoreductive surgery is of the utmost importance for long-term survival. The ability to visualize minuscule tumor deposits is important to ensure complete resection of the tumor. The purpose of our study was to estimate the in vivo sensitivity, specificity and diagnostic accuracy of an intra-operative fluorescence imaging system combined with an α(v)β(3)-integrin targeted near-infrared fluorescent probe. METHOD Tumor bearing mice were injected intravenously with a fluorescent probe targeting α(v)β(3) integrins. Fluorescent spots and non-fluorescent tissue were identified and resected. Standard histopathology and fluorescence microscopy were used as gold-standard for tumor detection. RESULTS Fifty-eight samples excised with support of intra-operative image-guided surgery were analyzed. The mean target to background ratio was 2.2 (SD 0.5). The calculated sensitivity of the imaging system was 95%, and the specificity was 88% with a diagnostic accuracy of 96.5%. CONCLUSION Near-infrared image-guided surgery in this model has a high diagnostic accuracy and a fair target to background ratio that supports the development towards clinical translation of α(v)β(3)-integrin targeted imaging.

Abstract
AIM This study compares lymphatic mapping in early gastric cancer with ICG and infrared ray electronic endoscopy (IREE) to ICG alone. It examines the optimal method for intra-operative detection of metastases and shows long term follow up results. METHODS 212 patients underwent the SN procedure with IREE and peritumoural ICG injection. Evaluated parameters were detection of sentinel nodes with IREE versus ICG alone, intra-operative detection rate of lymph node (LN) metastasis with node picking versus lymphatic basin dissection (LBD) and lymphatic drainage patterns. RESULTS 34 patients had LN metastases. The SN identification rate and sensitivity for IREE versus ICG alone were 99.5 versus 85.8% and 97.0 versus 48.4% respectively. Intra-operative accuracy for detecting LN metastasis was 50% with node picking versus 92.3% with LBD. LN metastases were always in the SN basin. Lymphatic invasion and T-stage were risk factors for nodal metastases. Two patients showed recurrent disease. Both had a tumour with signet cell differentiation. One patient had a T3 tumour, the other patient had a tumour with a diameter of 85 mm. CONCLUSION The SN procedure with IREE can detect the SN and is better than ICG alone. LBD of the SN basin is required for accurate intra-operative diagnosis of metastases. LBD dissection based on IREE is a safe method of nodal dissection in patients with T1 or limited T2 tumours.

Abstract
AIMS We evaluated the effect of modified Davidson's fixative (mDF) on the number of lymph nodes examined and staging in patients with colon carcinoma. METHODS The results of two different fixation methods used in the pathological preparation of the resection specimens were analyzed. A traditional formalin preparation with manual dissection of all nodes was performed in 117 colon specimens between January 2003 and July 2004. After July 2004, the resected specimens of 125 patients was fixated in mDF. Differences in the retrieval and number of nodes and size of suspected nodal metastases were measured. All lymph nodes were stained with conventional H&E methods. RESULTS The median number of examined nodes increased from 5 (0-17) to 13 (0-35) nodes after the introduction of mDF (p<0.001). The type of resection and the T-stage influenced the number of retrieved nodes significantly. The percentage of node-positive cases increased from 30% to 41% (p=0.077) with mDF, the median size of the retrieved lymph nodes decreased from 9 mm before to 6 mm after mDF (p<0.001) and more micrometastases were found (6% vs. 16%, p=0.03). CONCLUSIONS With mDF technique more lymph nodes were retrieved in the resected colon specimens. Smaller nodes and more micrometastases were found, leading to more node positive patients.

Abstract
AIMS Aim of this study was to examine the presence and the prognostic impact of immunohistochemically identified nodal micrometastases in patients with gastro-oesophageal junction (GEJ) carcinomas. METHODS Between January 1988 and December 2000, 148 patients underwent a radical (R0) resection with a two-field lymphadenectomy for a GEJ carcinoma. Specimens of 60 patients in whom conventional haematoxylin and eosin (H & E) examination did not demonstrate lymph-node metastases (pN0) were available for immunohistochemical (IHC) analysis using antibodies AE1/AE3 directed against cytokeratins. Paraffin embedded material of all retrieved lymph nodes in these patients were serially sectioned and analysed by one pathologist after H & E examination for the presence of micrometastases by IHC. RESULTS In 60 resection specimens initially staged as pN0 a total of 524 lymph nodes were available for IHC analyses. Micrometastases were detected in 126 out of 524 lymph nodes (24%), corresponding with 18 of the 60 patients (30%) who were upstaged by this technique. Compared with the pN0 group, the disease free survival (DFS) was significantly lower in patients with nodal involvement at IHC (p<0.001). Survival of patients with IHC identified micrometastatic disease was comparable to those with H & E positive lymph nodes. CONCLUSIONS Micrometastases in regional nodes were detected by cytokeratin-specific IHC in 30% of radical resected GEJ tumours without overt nodal involvement. Their presence conveys a worse prognosis with a significant reduced DFS, suggesting that the finding of micrometastases should be included in the staging system.

Abstract
Human immunodeficiency virus-associated dementia (HAD) is associated with increased numbers of activated central nervous system (CNS) macrophages. Chemokines, which regulate infiltration of macrophages, were measured in the cerebrospinal fluid (CSF) of human immunodeficiency virus (HIV)-negative and HIV-positive individuals with and without neurological disease. Monocyte chemotactic protein (MCP)-1 and RANTES (but not MCP-3), macrophage inflammatory protein (MIP)-1alpha, MIP-1beta, or interleukin-8 (IL-8) was higher in HAD. MCP-1 correlated with CSF viral load and severity of dementia, and it increased over time in patients who developed dementia.
