Perforated Appendix in a Neonate: A Review of Literature and a Case Report from Northern Tanzania

Acute perforated appendicitis is rare in neonates and is associated with high morbidity and mortality. This is mainly because the rarity of the pathology and the abnormal clinical features cause delays in diagnosis and definitive management. We report a case of a premature neonate who presented with sudden onset of abdominal distension associated with an inability to pass stools. The initial abdominal X-ray showed free air under the right hemi-diaphragm. An emergency laparotomy was performed revealing a perforation at the appendicular tip. An appendectomy was done, and the neonate recovered well with a mild surgical site infection during the course of recovery. Neonatal perforated appendicitis is rare, and clinicians need to consider it as a differential diagnosis due to the atypicalpresentations. This preterm neonate presented with clinical features of intestinal obstruction and was found at laparotomy to have a perforated appendix at the tip due to neonatal appendicitis.

An Experience with 31 Cases of Neonatal Appendicitis: A Retrospective Study

Background: Neonatal appendicitis (NA) is rarely diagnosed due to lack of specific symptoms and signs. The aim of this study is to share our experience with NA.Methods: We performed a retrospective data review from electronic medical records of patients admitted at Children’s Hospital of Chongqing Medical University (CHCMU) with the clinical diagnosis of NA from October 2001 to July 2018.Results: Of 31 neonates, male neonates (n=20) accounted for 64.5%. Abdominal distension and anorexia were the most common clinical features (61.3%, n=19). Neonates with elevated C- reactive protein (CRP) accounted for 92.6% (n=25) where as 51.6% (n=16) had normal white blood cell count (WBC). Of 29 neonates who underwent surgery, 69% (n=20) had perforated appendicitis.Conclusion: Neonatal appendicitis lacks specific clinical features, and early diagnosis is difficult. Clinicians need to have high index of suspicion when attending neonates with features of abdominal sepsis.

Colon stenosis due to acute neonatal appendicitis in a preterm baby: a case report

Background Colon stenosis and acute appendicitis are rare diseases among premature babies. To the best of our knowledge, no study has identified both the conditions in preterm babies. Case presentation Here we report a case of a preterm Japanese male baby who developed ascending colon stenosis and appendicitis. During his neonatal intensive care unit stay, he developed increasing apnea and vomiting with rapidly worsening abdominal distention. Contrast radiographs indicated colon stenosis. Emergent exploratory laparotomy revealed ascending colon stenosis with appendix adhesion; both the lesions were surgically resected. The pathological findings suggested that he had appendicitis several weeks prior to the surgery; the onset of colon lesion seemed later than that of appendix. The perforated appendix was covered by the ascending colon, and inflammatory reactions led to the narrowing of the intestinal lumen. Conclusions Neonatal appendicitis and colon stenosis are both challenging for the diagnosis, and early laparotomy is necessary when these conditions are suspected.
