NEONATAL BILIOUS VOMITING- PART 1 & 2 Dear Viewers, Greetings from “Surgical Educator” Today I have uploaded two videos on “Neonatal bilious Vomiting- Part 1 & 2. In this episode, I talked about various congenital causes for bowel obstruction in neonatal babies that also cause bilious vomiting. Since there are many causes, I have created two videos to cover everything. In Part1, I talked about duodenal atresia, annular pancreas, malrotation, jejunal & ileal atresia and necrotising enterocolitis. In Part2, I talked about Hirschsprung’s disease, meconium ileus, meconium plug, small left colon syndrome and meconium peritonitis. I request you to watch both videos together and I hope you will enjoy them. You can watch all my surgical teaching video casts in the following links: Surgicaleducator.blogspot.com Youtube.com/c/surgicaleducator Thank you for your support.

- 5. HIRSCHSPRUNG’S DISEASE Craniocaudal migration of ganglion cells of the bowel begins at 12th wk of gestation Arrest of this migration produces an aganglionic segment of bowel-absence of Aurbach’s & Meissener’s plexus This aganglionic segment of bowel unable to relax & peristaltic wave stops proximally- functional obstruction Incidence 1 in 5000 Male:Female 4:1
- 6. HIRSCHSPRUNG’S DISEASE Mutations in RET proto-oncogene are commonly associated with Hirschsprung’s disease Not passed/ delayed passage of meconium Abdominal distension Bilious vomiting Fever & diarrhea suggest Toxic megacolon
- 8. HIRSCHSPRUNG’S DISEASE Workup AXR: Dilated Bowel Loops Barium Enema: Swan Neck Appearance
- 9. HIRSCHSPRUNG’S DISEASE Workup Absence of ganglion cells in myenteric plexus Suction rectal bx Noblet Rectal Mucosal Suction Biopsy Gun
- 10. HIRSCHSPRUNG’S DISEASE Management Empty bowel with saline enema (30 to 50 ml) daily If can successfully decompress the bowel- continue rectal washouts for 45 days If unable to decompress the bowel- do Rt transverse colostomy or Levelling colostomy

- 15. HIRSCHSPRUNG’S DISEASE De La Torre’s Transanal Endorectal Pullthrough
- 16. MECONIUM ILEUS Uncomplicated cases show impacted meconium in terminal ileum- inspissated tar like meconium Accounts for 9 to 10% of all neonatal intestinal obstructions Present in 8 to 10% of cystic fibrosis patients at birth Complicated cases include volvulus,perforation and peritonitis with sepsis
- 17. MECONIUM ILEUS Signs depend on degree of obstruction and complications Significant abdominal distension may develop during neonatal period General status progressively deteriorates with incipient sepsis in cases of perforation In perforation, the scrotum or labia may have greenish discoloration due to patent processus vaginalis
- 18. MECONIUM ILEUS
- 19. MECONIUM ILEUS- Imaging Studies Disparate sized bowel loops Soap bubble appearance- Neuhauser’s sign
- 20. MECONIUM ILEUS- Management 60 to 70% of simple Meconium ileus can be successfully treated with Gastrograffin enema Other 30% need operative management Goal of surgery is to remove the abnormal meconium from GIT & maintain adequate length of bowel Surgery consists of resection& anastomosis of involved segment and/or roux-en-y ileostomy
- 22. MECONIUM ILEUS- Management Paul Mikulicz Double Barrel Ileostomy Bishop-Koop’s Distal chimney Ileostomy Santulli’s Proximal chimney Ileostomy
- 23. MECONIUM PLUG A long plug of mucus and sticky meconium in rectum & distal colon results low intestinal obstruction Due to immaturity of colonic & rectal expulsive mechanism Often associated with neonatal Hirschsprung’s disease Rectal exam/rectal wash results in expulsion of the plug and relief of intestinal obstruction
- 24. MECONIUM PLUG
- 25. MECONIUM PERITONITIS Intrauterine perforation of intestineleakage of meconium into peritoneal cavity reaction of peritoneum to this leaked meconium Due to intrauterine vascular compromise of intestine ischemia&perforation as early as 4th month of intrauterine life Different pathological typesMeconium pseudocyst, generalised adhesive peritonitis,meconium ascites & infected meconium peritonitis
- 26. MECONIUM PERITONITIS Often associated with cystic fibrosis & Prognosis is poor Bilious vomiting, failure to pass meconium and abdominal distension Abdominal wall edema, erythema and free fluid in peritoneal cavity AXR multiple air fluid levels and peritoneal calcifications Surgical treatment releasing of adhesions, removal of devitalised tissues, closure of perforation, intestinal resection& anastomosis
