Revisional Surgery After One Anastomosis/Minigastric Bypass: an Italian Multi-institutional Survey

Background: Efficacy and safety of OAGB/MGB (one anastomosis/mini gastric bypass) have been well documented both as primary and as revisional procedures. However, even after OAGB/MGB, revisional surgery is unavoidable in patients with surgical complications or insufficient weight loss. Methods: A questionnaire asking for the total number and demographics of primary and revisional OAGB/MGBs performed between January 2006 and July 2020 was e-mailed to all S.I.C. OB centres of excellence (annual caseload > 100; 5-year follow-up > 50%). Each bariatric centre was asked to provide gender, age, preoperative body mass index (BMI) and obesity-related comorbidities, previous history of abdominal or bariatric surgery, indication for surgical revision of OAGB/MGB, type of revisional procedure, pre- and post-revisional BMI, peri- and post-operative complications, last follow-up (FU). Results: Twenty-three bariatric centres (54.8%) responded to our survey reporting a total number of 8676 primary OAGB/MGBS and a follow-up of 62.42 ± 52.22 months. A total of 181 (2.08%) patients underwent revisional surgery: 82 (0.94%) were suffering from intractable DGER (duodeno-gastric-esophageal reflux), 42 (0.48%) were reoperated for weight regain, 16 (0.18%) had excessive weight loss and malnutrition, 12 (0.13%) had a marginal ulcer perforation, 10 (0.11%) had a gastro-gastric fistula, 20 (0.23%) had other causes of revision. Roux-en-Y gastric bypass (RYGB) was the most performed revisional procedure (109; 54%), followed by bilio-pancreatic limb elongation (19; 9.4%) and normal anatomy restoration (19; 9.4%). Conclusions: Our findings demonstrate that there is acceptable revisional rate after OAGB/MGB and conversion to RYGB represents the most frequent choice

How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

The Role of Microbiota in Pancreatic Cancer

Pancreatic cancer (PC) has an unfavorable prognosis with few effective therapeutic options. This has led researchers to investigate the possible links between microbiota and PC. A disrupted gut microbiome can lead to chronic inflammation, which is involved in the pathogenesis of PC. In addition, some bacterial strains can produce carcinogens that promote the growth of cancer cells. Research has also focused on pancreatic and oral microbiota. Changes in these microbiota can contribute to the development and progression of PC. Furthermore, patients with periodontal disease have an increased risk of developing PC. The potential use of microbiota as a prognostic marker or to predict patients’ responses to chemotherapy or immunotherapy is also being explored. Overall, the role of microbiota—including the gut, pancreatic, and oral microbiota—in PC is an active research area. Understanding these associations could lead to new diagnostic and therapeutic targets for this deadly disease

A prognostic score from a multicentric retrospective analysis of patients affected by sarcoma with metachronous lung metastases undergoing metastasectomy

BackgroundDespite the lack of evidence-based on prospective randomized studies, surgery has become the cornerstone of the treatment in patients with pulmonary oligometastatic sarcomas. Our study aimed to construct a composite prognostic score for metachronous oligometastatic sarcoma patients. MethodsA retrospective analysis was performed on data patients who underwent radical surgery for metachronous metastases in six research institutes from January 2010 to December 2018. The log-hazard ratio (HR) obtained from the Cox model was used to derive weighting factors for a continuous prognostic index designed to identify differential outcome risks. ResultsA total of 251 patients were enrolled in the study. In the multivariate analysis, a longer disease-free interval (DFI) and a lower neutrophil-to-lymphocytes ratio (NLR) were predictive of a better overall survival (OS) and disease-free survival (DFS). A prognostic score was developed based on DFI and NLR data, identifying 2 risk class groups for DFS (3-years DFS 20.2% for the high-risk group [HRG]and 46.4% for the low-risk group [LRG] [<0.0001]) and 3 risk groups for OS (3 years OS 53.9% for the HRG vs. 76.9% for the intermediate-risk group and 100% of the LRG (p < 0.0001)). ConclusionThe proposed prognostic score effectively predicts outcomes for patients with lung metachronous oligo-metastases from the surgically treated sarcoma

External Validation of a Prognostic Model for Squamous-Cell Lung Cancer and Impact of Adjuvant Treatment in >1,300 Patients: Topic: Neoadjuvant and Adjuvant Chemotherapy

Background A risk classification model able to powerfully discriminate the prognosis of resected squamous-cell lung cancer (R-SqCLC) patients (pts) was developed (PilottoJTO 2015). Herein, we validate the model in a larger multicenter series of >1,300 R-SqCLC pts (AIRC project 14282). Methods R-SqCLC pts in 6 different institutions (01/2002 - 12/2012) were considered eligible. Each patient was assigned with a prognostic score to identify the individual risk of recurrence, on the basis of the clinico-pathological data according to the develop model (age, T-descriptor according to TNM 7th edition, nodes, and grading). Kaplan-Meier analysis for disease-free/cancer-specific/overall survival (DFS/CSS/OS) was performed according to the published 3-class risk model (Low: score 0-2; Intermediate: score 3-4; High: score 5-6). Harrell’s C-statistics was adopted for model validation. The effect of adjuvant chemotherapy (ACT) was adjusted with the Propensity Score (PS). Results Data from 1,375 pts from 6 institutions were gathered (median age: 68 years; male/female: 86.8%/13.2%; T-descriptor 1–2/3–4: 73.3%/26.7%; nodes 0/>0: 53.4%/46.6%; stages I-II/III-IV: 71.7%/28.3%); 384 pts (34.5%) underwent ACT. With a median follow-up of 55 months (95% CI 51-59), pts at Low-Risk had a significantly longer DFS in comparison with Intermediate- (HR 1.67, 95% CI 1.40-2.01) and High-Risk (HR 2.46, 95% CI 1.90-3.19) pts, as well as for CSS (HR 1.79, 95% CI 1.48-2.17; HR 2.33, 95% CI 1.76-3.07) and OS (HR 2.46, 95% CI 1.80-3.36; HR 4.30, 95% CI 2.92-6.33). C-statistics was 68.3 (95% CI 63.5-73.1), 68.0 (95% CI 63.2-72.9), and 66.0 (95% CI 61.6-71.1), for DFS, CSS and OS, respectively. 60-months DFS for Low-, Intermediate- and High-Risk pts was 51.0%, 33.5% and 25.8%, respectively (p<0.0001). 60-months CSS for Low-, Intermediate- and High-Risk pts was 82.7%, 64.7% and 53.3%, respectively (p<0.0001). 60-months OS for Low-, Intermediate- and High-Risk pts was 56.7%, 37.9% and 30.9%, respectively (p<0.0001). A significant benefit in DFS was found in favor of ACT (p=0.005), with no difference in CSS (p=0.57), although a trend in OS (p=0.16). Overall, no significant differences for ACT were found in DFS, CSS and OS when survival was corrected with PS analysis, although CSS and OS curves visually separate with a trend for ACT in Intermediate- and High-Risk pts. Conclusion The prognostic performance of the previously developed model was validated in a larger R-SqCLC pts’ series. Considering the overall dismal prognosis of such disease, the efficacy of ACT requires to be clearly established for Intermediate- and High-Risk pts, as well as that should be questioned for Low-Risk pts

Prognostic Model for Resected Squamous Cell Lung Cancer: External Multicenter Validation and Propensity Score Analysis exploring the Impact of Adjuvant and Neoadjuvant Treatment

Introduction: We developed one of the first clinicopathological prognostic nomograms for resected squamous cell lung cancer (SQLC). Herein, we validate the model in a larger multicenter cohort and we explore the impact of adjuvant and neoadjuvant treatment (ANT). Methods: Patients with resected SQLC from January 2002 to December 2012 in six institutions were eligible. Each patient was assigned a prognostic score based on the clinicopathological factors included in the model (age, T descriptor according to seventh edition of the TNM classification, lymph node status, and grading). Kaplan-Meier analysis for disease-free survival, cancer-specific survival (CSS), and overall survival was performed according to a three-class risk model. Harrell's C-statistics were adopted for model validation. The effect of ANT was adjusted with propensity score. Results: Data on 1375 patients were gathered (median age, 68 years; male sex, 86.8%; T descriptor 1 or 2 versus 3 or 4, 71.7% versus 24.9%; nodes negative versus positive, 53.4% versus 46.6%; and grading of 1 or 2 versus 3, 35.0% versus 41.1%). Data for survival analysis were available for 1097 patients. With a median follow-up of 55 months, patients at low risk had a significantly longer disease-free survival than did patients at intermediate risk (hazard ratio [HR] = 1.67, 95% confidence interval [CI]: 1.40\u20132.01) and patients at high risk (HR = 2.46, 95% CI: 1.90\u20133.19); they also had a significantly longer CSS (HR = 2.46, 95% CI: 1.80\u20133.36 versus HR = 4.30, 95% CI: 2.92\u20136.33) and overall survival (HR = 1.79, 95% CI: 1.48\u20132.17 versus HR = 2.33, 95% CI: 1.76\u20133.07). A trend in favor of ANT was observed for intermediate-risk/high-risk patients, particularly for CSS (p = 0.06 [5-year CSS 72.7% versus 60.8%]). Conclusions: A model based on a combination of easily available clinicopathological factors effectively stratifies patients with resected SQLC into three risk classes

Internet and social media use among patients with colorectal diseases (ISMAEL): a nationwide survey

Aim: Social media are used daily by both healthcare workers and patients. Online platforms have the potential to provide patients with useful information, increase their engagement and potentially revolutionize the patient-physician relationship. This survey aimed to evaluate the impact of the Internet and social media (I&amp;SM) on patients affected by colorectal and proctological diseases to define a pathway to develop an evidence-based communications strategy. Method: A 31-item anonymous electronic questionnaire was designed. It consisted of different sections concerning demographics and education, reason for the visit, knowledge of the diseases, frequency of I&amp;SM use and patients' opinions about physicians' websites. Results: Over a 5-month period, 37 centres and 105 surgeons took part in the survey, and a total of 5800 patients enrolled. Approximately half of them reported using the Internet daily, and 74.6% of the study population used it at least once per week. There was a correlation (P &lt; 0.001) between those who used the Internet for work and those who had knowledge of both symptoms and the likely diagnosis before consultation. Patients who used the Internet daily were more likely to request a consultation within 6 months of symptom onset (P &lt; 0.0001). Patients with anorectal diseases were more likely to know about their disease and symptoms before the visit (P &lt; 0.001). Conclusion: Colorectal patients use I&amp;SM to look for health-related information mainly after their medical visit. Surgeons and hospital networks should plan a tailored strategy to increase patient engagement, delivering appropriate information on social medi
