Advances in Pediatric MIS Over The Past Decade George W. Holcomb, III, M.D., MBA Surgeon-in-Chief Children’s Mercy Hospital Kansas City, Missouri
Advances in MIS • Development of Surgical Technique • Thoracoscopic lobectomy • Thoracoscopic repair EA/TEF • Single site umbilical laparoscopic surgery (SSULS) • Refinement in Surgical Technique • Laparoscopic fundoplication • Laparoscopic pyloromyotomy • Definition of Perforated Appendicitis • Evidence Based Studies in MIS • Consensus B/W Drs. Pena & Georgeson regarding laparoscopy for anorectal atresia with a fistula above the prostatic urethra (IPEG 2009)
Advances in MIS • Growth of IPEG • Development of good 3 mm instruments • Development of HD picture • Development of the stab incision technique
Development of A Surgical TechniqueThoracoscopic Repair EA/TEF – Lessons Learned • Baby should ideally be >2.5 kg • Bronchoscopy to identify fistula to gauge distance • Oscillating ventilator helpful • Is metal clip good for ligating TEF? • When to convert? • How to train staff and residents?
Development of A Surgical TechniqueThoracoscopic Repair EA/TEF – Lessons Learned Oscillating Ventilator Helpful
Development of A Surgical TechniqueThoracoscopic Repair EA/TEF – Lessons Learned Is the metal clip appropriate for ligating the TEF? Can a recurrent TEF be prevented? J Laparoendosc Adv Surg Tech 17:380-382, 2007
Development of A Surgical TechniqueThoracoscopic Repair EA/TEF – Lessons Learned • When to convert? • After ligation & division of TEF - if the gap is too large (2 -3 cm)? • How do we train staff and residents?
Thoracoscopic Repair EA/TEFResults(104 Patients) Mean Age (days) 1.2 (± 1.1) Mean Wt (kg) 2.6 (± 0.5) Mean Operative Time (min) 129.9 (± 55.5) Mean Days Ventilation 3.6 (± 5.8) Mean Hospitalization (days) 18.1 (± 18.6)
Thoracoscopic Repair EA/TEF(104 Patients) • Fistula Ligation • 37 pts: suture ligation • 67 pts: clip ligation Ann Surg 242: 422-430, 2005
Thoracoscopic Repair EA/TEFAssociated Anomalies(104 Patients)
Thoracoscopic Repair EA/TEFResults(104 Patients) • Fundoplication 26 (22 Nissen, 4 Thal) • Aortopexy 7 ( 6 thoracoscopic) • Duodenal atresia 4 (4 laparoscopic) • Imperforate anus 10 (7 high, 3 low) • Cardiac operations 5 ( other than VSD/ASD) Ann Surg 242: 422-430, 2005
Thoracoscopic Repair EA/TEFComplications(104 Patients) • Recurrent fistula 2 ( 3 mos, 8 mos) • Mortality 3 • 7 mo old - NEC • 10 day old – CHD • 21 day old with esophageal disruption at intubation Ann Surg 242: 422-430, 2005
Thoracoscopic Repair EA/TEFConversion to Open5 Pts • 1 Pt: R aortic arch (despite negative ECHO) • 3 Pts: Intraoperative desaturation, relatively long gap • 1 Pt: 1.2 kg baby – only 1 port placed – too small
Thoracoscopic Repair EA/TEF104 Patients Waterston A: > 5.5 lb with no significant associated problems Waterston B: 4-5.5 lbs. or higher weight with moderate pneumonia or congenital anomaly Waterston C: weight < 4 lb or higher weight with severe pneumonia or congenital anomaly
Thoracoscopic Repair EA/TEF N.R.: Not reported A: 87% are Gross Type C B: Stricture is defined as a significant narrowing on the initial esophagram C: Stricture in this paper is defined as requiring > 4 dilations D: Stricture in this paper is defined as requiring > 2 dilations
EA/TEF Operative Approach ThoracoscopyThoracotomy
Thoracoscopic Repair EA/TEFAdvantages of Thoracoscopy • Avoidance of musculoskeletal sequelae • Superior visualization of anatomy • Easy to identify fistula for ligation
How To Get StartedNot The Ideal Case • 2 - 2.5 kg • Very high upper pouch • Complex single ventricle physiology • Prostaglandin dependent
How To Get StartedIdeal Case • Baby – 2.5-3 kg; no other anomalies • Esophageal segments close together (CXR, Bronchoscopy) • Start thoracoscopically – Go as far as comfortable • Try it again
Development of a Surgical TechniqueThoracoscopic Lobectomy – Lessons Learned • Upper lobes are very difficult, esp. if training residents • Middle & lower lobes are easier b/c are “end organs” • Single lung ventilation very helpful – need good anesthesiologist • For prenatally discovered CPAM, better to wait until baby is 6-9 mos of age (assuming asymptomatic)

Development of a Surgical TechniqueSSULS • Why did it develop? • Who benefits patient or surgeon? • What operations are applicable? • Special equipment needed?
SSULSWhat Operations Are Applicable? • Appendectomy • Cholecystectomy • Splenectomy • Ileal or colonic resection (IBD or segmental lesion) – extra-corporeal anastomosis • Pyloromyotomy
SSULSSpecial Equipment • SILS port (Covidien, Inc.) • Cholecystectomy • Splenectomy • Segmental ileal or colonic resection • Long telescope (300, 450)
SSULS Appendectomy
Refinement in TechniqueLap. Fundoplication • Cautery in pts <4-5 yrs • Minimal esophageal dissection/mobilization
