Primary anastomosis for meconium peritonitis: first choice of treatment

Untitled

“…2 Like in our patient, the bowel distal to the pseudocyst is usually unused and of small caliber. 3,4 There are many differential diagnoses for intraabdominal calcifications in the newborn period, most of them neoplastic. 5 However, "eggshell calcifications" are pathognomonic for meconium pseudocysts.…”

“…6 Resection of the pseudocyst as well as the segment of small bowel followed by an enteral anastomosis is the treatment of choice. 3,4 Conclusion Meconium pseudocysts are easy to recognize and an important radiologic spot diagnosis that every pediatrician and pediatric surgeon should be aware of. Resection of the pseudocyst is the therapy of choice and can be undertaken electively in the first days of life.…”

“…2 The bowel perforation may have different causes including atresia, stricture, meconium ileus, internal hernia, volvulus, intussusception, duplication, or Meckel's diverticulum. 2,3 Meconium peritonitis leads to inflammation and fibrosis (fibroadhesive-type) and can be complicated by the presence of pseudocysts (cystic-type). 4 The typically rimcalcified cysts lack an intestinal epithelial layer due to inflammation by digestive enzymes.…”

Meconium peritonitis: an interesting entity

“…Neonatal outcomes have improved over time as a result of better diagnosis antenatally and with modern advances in paediatric surgery and perinatology 5. Surgery remains the definitive treatment with procedures including multiple drainage procedures, stoma creation and final ostomy closure 6…”

Giant cystic meconium peritonitis presenting in a neonate with classic radiographic eggshell calcifications and treated with an elective surgical approach: a case report

“…Outcomes for neonatal meconium peritonitis have improved over time, with relatively high mortality rates reported from the 1950s improving to a survival rate of about 90% with modern advances in pediatric surgery and perinatology [13]. Surgery remains the definitive treatment, but there is a lack of standardization in the literature.…”
