Topic Overview

A pediatric surgery webinar complications session covering three cases: a newborn with prenatally diagnosed congenital lung lesion requiring lobectomy with intraoperative pulmonary vein bleeding, a child with symptomatic paraesophageal hernia after prior Nissen fundoplication requiring repair with subsequent dysphagia, and a 35-week neonate with esophageal atresia complicated by esophageal-lung fistula and absent right mainstem bronchus. The discussion emphasizes technical decision-making around timing of intervention, device selection, recognition of anatomic variants, and management of postoperative complications.

Key Takeaways

  • Place safety silk suture on pulmonary vein before stapling/energy—prevents retraction if primary seal fails during lobectomy (18:40)
  • Posterior crural sutures placed too anteriorly cause post-Nissen obstruction; use bougie intraop to detect hang-up at GE junction (36:46)
  • Dysphagia <2 weeks post-Nissen is too early for dilation; wait 4-6 weeks for swelling to resolve before intervention (32:49)
  • Always bronchoscope esophageal atresia cases to identify additional fistulas or airway anomalies before repair (54:34)
  • In children, use biologic mesh for hiatal hernia—permanent mesh risks erosion into esophageal lumen (26:52)

Open questions

  • What is the true malignancy risk in prenatally diagnosed congenital lung lesions to guide observation versus resection decisions?
  • What percentage of newborns with prenatal lung lesions have negative chest X-rays that never require CT scanning?
  • In paraesophageal hernia repair, does biologic mesh provide durable reinforcement or is it ineffective as adult data suggests?
  • What is the optimal anticoagulation strategy for neonates on ECMO who develop recurrent arterial cannula clots?
  • Can tracheal reconstruction with bronchial reimplantation provide long-term functional outcomes in esophageal-lung fistula cases?

Why fundoplication exists as a distinct problem

Gastroesophageal reflux in children with neurologic impairment, anatomic anomalies, or failed medical management creates a clinical dilemma: the lower esophageal sphincter cannot maintain competence, yet the patient cannot tolerate chronic aspiration or esophagitis 0:00. Fundoplication — wrapping the gastric fundus around the distal esophagus to create a mechanical barrier — became the standard surgical solution 0:00. But as one of the discussants put it, the operation represents "trying to do a mechanical fix to a physiologic problem" 44:09. The operation works by imposing anatomy where physiology has failed, which makes it inherently prone to failure modes that medical management does not address.

The core clinical problem

Paraesophageal hernias after Nissen fundoplication represent one of the most common and vexing complications 21:40. The fundal wrap migrates through the hiatus into the chest, causing obstruction, pain, and recurrent reflux 21:40. Medical therapy alone will not resolve symptomatic paraesophageal hernias; they continue to progress and require surgical repair 24:09. The challenge is not simply reducing the hernia — it is understanding which of several structures is causing the obstruction and preventing recurrence without creating new problems 36:46 38:20.

How the repair works

The revision begins with reducing the herniated stomach back into the abdomen and assessing the fundoplication itself 21:40. The wrap may be intact, too tight, or disrupted 38:20. The hiatus may be widened 25:54. The posterior crural sutures — placed to narrow the esophageal opening in the diaphragm — may be creating a pinch point 36:46.

If the crura come together easily without tension, primary repair without mesh is preferred 25:54. When reinforcement is necessary, biologic mesh is safer than permanent mesh in children due to the risk of erosion into the esophageal lumen 26:52. Adult data suggests mesh reinforcement reduces recurrence rates 27:19, but the pediatric literature is thinner and practice varies.

The critical technical insight is that the esophagus courses anterior-to-posterior as it crosses the diaphragm 36:46. Posterior crural sutures placed too anteriorly create a pinch point where the esophagus angles across the repair 36:46. Intraoperative contrast or endoscopy can identify whether the crura or the fundoplication itself is causing obstruction 38:20. Using a bougie during the operation and observing for hang-up at the gastroesophageal junction allows real-time identification of overly tight posterior crural sutures 41:07. Some surgeons have eliminated posterior crural sutures entirely, using a minimal dissection technique that creates the retroesophageal window but leaves the posterior crura alone 41:54.

Where practice is contested

Postoperative dysphagia is common but its management is debated 32:49. Dysphagia within two weeks of fundoplication is too early for dilation; waiting four to six weeks allows swelling to resolve 32:49. One surgeon who underwent the procedure himself reported that swallowing normalized on day 18 33:54. The question is whether early obstruction represents edema that will resolve or a technical problem requiring revision 32:49. Placing a feeding tube and waiting four to six weeks is reasonable if the obstruction is incomplete, but operating at two to three weeks risks maximal inflammation 32:49.

Mesh use is similarly contested 26:52 27:19. Biologic mesh may resorb before the repair has fully healed, but permanent mesh can erode through the esophagus 26:52. One of the discussants described removing non-biological mesh from the esophageal lumen on endoscopy after it eroded through 26:52. The adult literature favors mesh, but the pediatric population is different — longer life expectancy, different tissue characteristics, and higher stakes for a permanent foreign body 26:52 27:19.

When to involve this team

Refer when a patient with prior fundoplication develops new or worsening dysphagia, vomiting, chest pain, or inability to tolerate oral intake 21:40 24:09. Imaging showing a paraesophageal hernia in a symptomatic patient warrants surgical consultation 24:09. Do not wait for malnutrition or aspiration pneumonia to develop.

For patients requiring multiple revisions, gastric disconnection may be the definitive solution 45:22. This is particularly true in cognitively impaired patients who do not take much by mouth and have failed multiple fundoplications 45:22. The operation separates the stomach from the esophagus entirely, eliminating reflux at the cost of permanent gastrostomy dependence 45:22. It is not a first-line option, but for the right patient it ends the cycle of failed repairs 45:22.

The broader lesson is that fundoplication is not a durable solution for many patients 44:09. The mechanical fix does not address the underlying physiology, and the wrap is subject to migration, disruption, and obstruction 21:40 36:46 44:09. Surgeons who perform fundoplication must be prepared to manage its complications, and referring clinicians should recognize that a history of fundoplication does not mean the reflux problem is solved 24:09 44:09.

Takeaways from this story

  • Posterior crural sutures placed too anteriorly create a pinch point as the esophagus angles across the diaphragm — use a bougie intraoperatively to detect this.
  • Biologic mesh is safer than permanent mesh in children due to erosion risk, though adult data favors mesh for reducing recurrence.
  • Dysphagia within two weeks post-fundoplication is too early for dilation; wait four to six weeks for edema to resolve before intervening.
  • Symptomatic paraesophageal hernias will not resolve with medical therapy and require surgical repair to prevent progression.
  • Gastric disconnection is definitive for patients with multiple failed fundoplications who are gastrostomy-dependent and cognitively impaired.
