ABSTRACT
Adenoid cystic carcinoma (AdCC) is a rare tumor that typically develops in the salivary glands and less frequently in other sites of the head and neck region. Only a few cases of resected metachronous liver metastases have been reported. Minimally invasive surgery is currently the gold standard of care for liver resections; furthermore, the use of Indocyanine Green (ICG) is continuously increasing in surgical practice, especially in cases of primary liver tumors and colorectal liver metastases, due to its capacity to enhance liver nodules. We report the case of a 54-year-old male with a single liver metastasis of AdCC, located in SIII, who presented in our center 9 months after resection of a primary tumor of the laryngotracheal junction and adjuvant proton therapy. A 25-mg injection of ICG (0.3â mg/kg) was administered 48â h before surgery in order to highlight the tumor and perform an ICG-guided resection. The lesion was clearly visible during surgery, and, given its position and the proximity to the main lobar vessels of the left lobe, we opted for a left lateral sectionectomy. The outcome was unremarkable, with no major postoperative complications. The administration of ICG 48â h before surgery seems to be a valid tool even in cases of AdCC liver metastases, providing surgeons with better visualization of the lesion and improving the precision of the resection.
ABSTRACT
Background: Acute appendicitis (AA) is one of the most common emergencies in general surgery worldwide. During the pandemic, a significant decrease in the number of accesses to the emergency department for AA has been recorded in different countries. A systematic review of the current literature sought to determine the impact of Coronavirus Disease 2019 (COVID-19) on hospital admissions and complications of AA. Method: A systematic search was undertaken to identify repeated cross-sectional studies reporting the management of AA during the COVID-19 pandemic (index period) as compared to the previous year, or at the turn of lockdown (reference period). Data were abstracted on article (country of origin) and patients characteristics (adults, children [i.e. non adults, <18-year-old]), or mixed population) within the two given timeframes, including demographics, number of admissions for AA, number of appendectomies, and complicated appendectomies. Results: Of 201 full-text articles assessed for eligibility, 54 studies from 22 world countries were included. In total, 27 (50%) were conducted on adults, 12 (22%) on children, and 15 (28%) on a mixed patients population. The overall rate ratio of admissions for AA between the two periods was 0.94 (95%CI, 0.75-1.17), with significant differences between studies on adults (0.90 [0.74-1.09]), mixed population (0.50 [0.27-0.90]), and children (1.50 [1.01-2.22]). The overall risk ratio of complicated AA was 1.65 (1.32-2.07), ranging from 1.32 in studies on children, to 2.45 in mixed population. Conclusion: The pandemic has altered the rate of admissions for AA and appendectomy, with parallel increased incidence of complicated cases in all age groups.
ABSTRACT
Due to the COVID-19 crisis, many scheduled medical and surgical activities have been suspended. This interruption to the healthcare system can negatively affect the diagnosis and management of melanoma. Neglecting melanoma throughout the outbreak may be associated with increased rates of mortality, morbidity, and healthcare expenses. We performed a retrospective review of all dermatological and surgical activity performed in our Melanoma Skin Unit between 23 February 2020 and 21 May 2020 and compared these data with those from the same period in 2019. During the lockdown period, we observed a decrease in dermatologic follow-up (DFU) (-30.2%) and in surgical follow-up (SFU) (-37%), and no modification of melanoma diagnosis (-3%). Finally, surgical excisions (SE) (+ 31.7%) increased, but sentinel lymph node biopsy (SLNB) (-29%) and lymph node dissections(LND) (-64%) decreased compared to the same period in 2019. Our experience supports the continuation of surgical and diagnostic procedures in patients with melanoma during the COVID-19 pandemic. Surgical and follow-up procedures for the diagnosis and treatment of melanoma should not be postponed considering that the pandemic is lasting for an extended period.
