Abstract
INTRODUCTION Multiple laparotomies, immunosuppressive therapy, wound infection, and malnutrition are risk factors for incisional hernia development, which places inflammatory bowel disease (IBD) patients at high risk. With advances in minimally invasive techniques, this study assesses incisional hernia repair techniques and complications in the IBD population. METHODS A single-center, retrospective review of adults with IBD who underwent incisional hernia repair from 2008 to 2022. Complications relative to operative approach and mesh placement location were assessed using descriptive and univariate statistics. RESULTS Eighty-eight IBD patients underwent incisional hernia repair. Fifty-two (59.1%) were on immunomodulators and 30 (34.1%) were repaired primarily. Thirty-five (39.7%) hernias recurred, of whom 19 (33%) had mesh placed. Three (30%) occurred in onlay repairs and 16 (33%) occurred in underlay repairs. Subdivision of underlay repairs into intraperitoneal, preperitoneal and retrorectus mesh placement revealed recurrence rates of 35.1%, 50%, and 14.3%, respectively. Patients with open repair were more likely to have intraoperative bowel injury (28.6% vs 9.7%, p = 0.041) and develop postoperative seromas/abscesses (12.5% vs 0%, p = 0.001) and wound complications (17.9% vs 0%, p = 0.012) compared to laparoscopic. Seromas/abscesses developed more frequently in onlay repairs compared to underlay (40% vs 2.13%, p = 0.001). Twelve (13.6%) patients presented with postoperative small bowel obstruction (SBO), 7 (58.3%) of whom had mesh placed, and 6 (85.7%) were underlay. All SBO after underlay repair had intraperitoneally placed mesh. When comparing surgeons, hernias were more likely to recur performed by colorectal surgeons compared to hernia surgeons (63.3% vs 21.3%, p < 0.001). CONCLUSION In IBD patients, minimally invasive approaches lead to fewer perioperative complications compared to open. Underlay mesh placement demonstrated decreased incidence of seroma/abscess formation compared to onlay. When sub-grouped, underlay placements were similar in terms of complications. Retrorectus placement, however, had fewer recurrences and no readmissions for SBO. This suggests a minimally invasive approach or placement of retrorectus mesh may provide the optimal repair in this patient population.

Abstract
BACKGROUND Colorectal liver metastases (CRLM) occur in roughly half of patients with colorectal cancer. Minimally invasive surgery (MIS) has become an increasingly acceptable and utilized technique for resection in these patients, but there is a lack of specific guidelines on the use of MIS hepatectomy in this setting. A multidisciplinary expert panel was convened to develop evidence-based recommendations regarding the decision between MIS and open techniques for the resection of CRLM. METHODS Systematic review was conducted for two key questions (KQ) regarding the use of MIS versus open surgery for the resection of isolated liver metastases from colon and rectal cancer. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Additionally, the panel developed recommendations for future research. RESULTS The panel addressed two KQs, which pertained to staged or simultaneous resection of resectable colon or rectal metastases. The panel made conditional recommendations for the use of MIS hepatectomy for both staged and simultaneous resection when deemed safe, feasible, and oncologically effective by the surgeon based on the individual patient characteristics. These recommendations were based on low and very low certainty of evidence. CONCLUSIONS These evidence-based recommendations should provide guidance regarding surgical decision-making in the treatment of CRLM and highlight the importance of individual considerations of each case. Pursuing the identified research needs may help further refine the evidence and improve future versions of guidelines for the use of MIS techniques in the treatment of CRLM.

Abstract
BACKGROUND While surgical resection has a demonstrated utility for patients with colorectal liver metastases (CRLM), it is unclear whether minimally invasive surgery (MIS) or an open approach should be used. This review sought to assess the efficacy and safety of MIS versus open hepatectomy for isolated, resectable CRLM when performed separately from (Key Question (KQ) 1) or simultaneously with (KQ2) the resection of the primary tumor. METHODS PubMed, Embase, Google Scholar, Cochrane CENTRAL, International Clinical Trials Registry Platform (ICTRP), and ClinicalTrials.gov databases were searched to identify both randomized controlled trials (RCTs) and non-randomized comparative studies published during January 2000-September 2020. Two independent reviewers screened literature for eligibility, extracted data from included studies, and assessed internal validity using the Cochrane Risk of Bias 2.0 Tool and the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed using risk ratios (RR) and mean differences (MD). RESULTS From 2304 publications, 35 studies were included for meta-analysis. For staged resections, three RCTs and 20 observational studies were included. Data from RCTs indicated MIS having similar disease-free survival (DFS) at 1-year (RR 1.03, 95%CI 0.70-1.50), overall survival (OS) at 5-years (RR 1.04, 95%CI 0.84-1.28), fewer complications of Clavien-Dindo Grade III (RR 0.62, 95%CI 0.38-1.00), and shorter hospital length of stay (LOS) (MD -6.6 days, 95%CI -10.2, -3.0). For simultaneous resections, 12 observational studies were included. There was no evidence of a difference between MIS and the open group for DFS-1-year, OS-5-year, complications, R0 resections, blood transfusions, along with lower blood loss (MD -177.35 mL, 95%CI -273.17, -81.53) and shorter LOS (MD -3.0 days, 95%CI -3.82, -2.17). CONCLUSIONS Current evidence regarding the optimal approach for CRLM resection demonstrates similar oncologic outcomes between MIS and open techniques, however MIS hepatectomy had a shorter LOS, lower blood loss and complication rate, for both staged and simultaneous resections.

Abstract
Background Acute appendicitis cases increased in severity following COVID-19–related restrictions in March, 2020. We investigated if similar changes occurred during Wave 2. Methods Acute appendicitis patients during Wave 1 were grouped 8 weeks before (Group A) and after (Group B) stay-at-home restrictions were initiated on March 15, 2020. Cases in Wave 2 were grouped 8 weeks before (Group C) and after (Group D) November 6, 2020. Groups were compared to equivalent time frames in 2018/2019. Results Group A versus B revealed 42.6% decrease (confidence interval: − 59.4 to − 25.7) in uncomplicated appendicitis and 21.1% increase (confidence interval: 4.8–37.3) in perforated appendicitis. Similar patterns were noted comparing Group C versus D without statistical significance. The changes seen in Wave 1 were significantly different than in 2018/2019. This trend continued in Wave 2. Conclusion Similar to Wave 1, acute appendicitis cases increased in severity during wave 2 of COVID-19, but with less prominence.

Abstract
Background The novel coronavirus (COVID-19) strain has resulted in restrictions potentially impacting patients presenting with acute appendicitis and their disease burden. Methods All acute appendicitis admissions (281 patients) between 1/1/2018-4/30/2020 were reviewed. Two groups were created: 6 weeks before (Group A) and 6 weeks after (Group B) the date elective surgeries were postponed in Massachusetts for COVID-19. Acute appendicitis incidence and disease characteristics were compared between the groups. Similar time periods from 2018 to 2019 were also compared. Results Fifty-four appendicitis patients were categorized in Group A and thirty-seven in Group B. Those who underwent surgery were compared and revealed a 45.5% decrease (CI: 64.2,-26.7) in uncomplicated appendicitis, a 21.1% increase (CI:3.9,38.3) in perforated appendicitis and a 29% increase (CI:11.5,46.5) in gangrenous appendicitis. Significant differences in the incidence of uncomplicated and complicated appendicitis were also noted when comparing 2020 to previous years. Conclusions The significant increase in complicated appendicitis and simultaneous significant decrease in uncomplicated appendicitis during the COVID-19 pandemic indicate that patients are not seeking appropriate, timely surgical care.

Abstract
We have previously shown that multiple vaccinations with 23-valent pneumococcal polysaccharide vaccine (PPV23s) resulted in attenuated antibody responses to subsequent 7-valent conjugate vaccine (PCV7) in asplenic adults with β-thalassemia major (Orthopoulos et al. Vaccine 2009; 27:350). However, there is evidence that PPV23-induced immune hyporesponsiveness could be overcome with time (Papadatou et al. Clin Infect Dis 2014; 59:862). In the current study we investigate the duration of hyporesponsiveness in the same cohort seven years after the original study vaccinations. Patients received one dose of 13-valent conjugate vaccine (PCV13) and antibody levels were measured before and one month after vaccination. Antibodies increased significantly after vaccination with PCV13, but were lower than post-PCV7 seven years earlier. Lower pre-vaccination antibody levels were associated with more robust response to PCV13. Our findings suggest that PPV23 should be used cautiously in asplenic adults vaccinated with multiple PPV23s in the past. Measurement of anti-pneumococcal antibodies before and after vaccination could be used to optimise timing of vaccinations and certify vaccine immunogenicity in such individuals.
