Investigation of optimal hernia repair techniques in patients with inflammatory bowel disease.

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.

Association Between the SARS-Cov2 Pandemic and Pediatric Surgical Consultations.

INTRODUCTION: The purpose of this study was to evaluate changes to acute pediatric surgical needs during the early phase of the SARS-Cov2 (COVID-19) pandemic. METHODS: We performed a retrospective cohort study of all in-hospital pediatric surgery consultations placed through the consult paging system at a single institution. We compared both median and absolute differences for emergency department (ED), operative, and hospital outcomes between March, April, and May of 2019 versus 2020. RESULTS: There were 225 in-hospital pediatric surgery consults in 2019 and 123 in 2020. Overall, mean age was 8.4-y (standard deviation = 6.4) and 60% were male. Initial vitals were similar between years and a similar proportion of patients underwent laboratory and imaging tests. In 2020, children spent a median of 1.1-h fewer in the ED (95% confidence interval = -2.2, -0.1) and 0.9-h fewer in the ED before surgical consultation (95% confidence interval = -1.5, -0.3) compared to 2019. Patients required significantly more procedures in the ED in 2020 (n = 16, 14.3%) than 2019 (n = 13, 6.2%) (P = 0.02), most commonly laceration repairs. In 2019, 46 children (20.4% of all consults in 2019) presented with appendicitis and 27 children (22.0% of all consults in 2020) in 2020. Complicated appendicitis was more common in 2020 (n = 12, 44.4%) than 2019 (n = 9, 19.6%) (P = 0.02). Two children (7.4%) were managed nonoperatively with a drain in 2020 compared to none in 2019 (P = 0.13). Median time from surgical consultation to surgery, median operative time, and median time to discharge was similar for children with appendicitis in both years. CONCLUSIONS: The early phase of the pandemic was associated with more efficient triaging in the ED, but more ED procedures and more complex surgical pathology.

Long-term results on the severity of acute appendicitis during COVID-19 pandemic.

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.
