RESUMO
Gastrointestinal basidiobolomycosis (GIB) is a rare fungal infection caused by Basidiobolus ranarum, a saprophytic fungus that belongs to the class of Basidiobolomycetes. It mainly infects immunocompetent individuals and is mainly found in arid tropical and subtropical regions, including Southwestern America, Saudi Arabia, Africa, and Asia. Not surprisingly, a great number of human infections have been reported from these warm, humid climate regions that are felicitous for the growth of this fungus, especially from the southern region of Saudi Arabia and Arizona in the United States of America. GIB is easily misdiagnosed as malignancy, inflammatory bowel disease, diverticulitis, lymphoma, and chronic intestinal infections due to its rarity. In this case series, we summarize the clinical features, imaging, histopathological features, and treatment of patients diagnosed with GIB in our institution.
RESUMO
Background Appendicitis is a frequent emergency condition. Surgical site infections (SSI) are a common complication of appendectomy. Despite improvements in infection control, SSIs continue to cause harm, prolonged hospital stays, and even death. Objective The objective of this study is to compare the risk of developing surgical site infections (SSIs) between open laparotomy and laparoscopic appendectomies in Al-Baha, Saudi Arabia. Methods This retrospective cohort study compared laparotomy and laparoscopy for post-operative surgical site infection among patients who underwent an appendectomy at King Fahad Hospital (KFH) in Albaha, Saudi Arabia. Medical record numbers (MRNs) of patients who met the inclusion criteria were collected to build the sampling frame. From the final sampling frame, simple random sampling using a random number generator was used to draw a representative sample. Data were collected from the surgical health records of the patients. The collected data included patients' demographics, comorbidities, presenting symptoms, ordered imaging studies, pre-operative shaving, type and duration of surgery, intraoperative findings, and signs of wound inflammation. Results The total number of patients included in the analysis was 256, who underwent surgery for acute appendicitis. Among those who underwent laparoscopy, 5.7% had to be converted to open laparotomy. Signs of surgical wound inflammation were found in 10.2% of the patients. Patients who underwent open laparotomy had a significantly higher risk of wound infection (RR=3.1, p-value=0.001). Further analysis revealed an effect modification of pre-operative shaving. Open laparotomy has a higher risk of wound infection among patients who have not had pre-operative shaving (RR=4.1 vs. RR=2.6), while both risks were statistically significant (p-value=0.033 and p-value=0.035), respectively. Complicated cases in intra-operative findings were found to have a higher risk of post-appendectomy SSI. Conclusion This study demonstrates that laparoscopic appendectomy carries a lower risk of surgical site infection (SSI) compared to open laparotomy. Additionally, pre-operative shaving of the surgical site was found to increase the incidence of SSI. Healthcare providers can use this information to enhance their practice and reduce the occurrence of surgical site infections. Whenever possible, laparoscopic appendectomy should be preferred over open laparotomy due to its substantially lower SSI risk. We also recommend vigilant monitoring of complicated appendectomy, particularly in cases of ruptured appendicitis, for signs of SSI.
