Chapters
- 0:00Case Presentation: Heterotaxy with Malrotation — 6-year-old female with heterotaxy syndrome, right atrial isomerism, single ventricle anatomy, situs inversus, and failure to thrive. Upper GI shows stomach on wrong side, duodenum without C-loop, cecum in right lower quadrant, and small bowel on left side.
- 2:35Management Discussion and Literature Review — Panel debates observation versus laparoscopic exploration. Discussion of right atrial isomerism volvulus risk, role of Ladd bands in failure to thrive, and Texas Children's data showing 0% volvulus in 95 heterotaxy patients (75% operated, 25% observed) but 11% small bowel obstruction rate post-Ladd procedure.
- 5:39Appendectomy Debate — Discussion of whether to perform appendectomy during laparoscopy, with consideration of appendix location and adhesion risk. One panelist performs inversion appendectomy for floppy cecum, another does not remove appendix if in correct location.
- 7:08Low-Lying Ligament of Treitz Scenario — Rapid-fire case: C-loop crossing midline with low-lying ligament of Treitz in otherwise normal child. Panel split between laparoscopic evaluation and observation. One institution reports subsequent volvulus in a watched patient with low-lying ligament of Treitz.
Key claims
- 0:16In malrotation with volvulus, you either operate or you get a new job — Speaker 1
- 2:44Right atrial isomerism has a higher incidence of malrotation compared to left atrial isomerism — Speaker 2
- 3:26In right atrial isomerism, children with malrotation are at higher risk for volvulus — Speaker 2
- 3:43Only one patient with left atrial isomerism had any real issues and it was not a true volvulus — Speaker 2
- 4:17Failure to thrive should be considered a GI symptom that may warrant intervention in malrotation — Speaker 4
- 4:47Texas Children's study of 95 consecutive heterotaxy patients with malrotation: three quarters underwent Ladd procedure, none volvulized post-op, but 11% had small bowel obstruction requiring admission and often surgery — Speaker 1
- 5:10In the Texas Children's study, 25% of heterotaxy patients were observed with no small bowel obstruction and no volvulus at 10-15 year follow-up — Speaker 1
- 5:46Appendectomy carries a slight complication risk from adhesions causing long-term obstruction — Speaker 1
- 5:58In situs inversus with malrotation, the appendix is in the correct location (double negative) — Speaker 3
- 6:43Symptomatic malrotation requiring operation includes significant pain, vomiting (possibly bilious), and bloody stools — Speaker 1
- 6:55The most common presentation of heterotaxy with malrotation is minimal symptoms: reflux, spitting up, and failure to thrive — Speaker 1
- 7:46Low-lying ligament of Treitz defines malrotation, not something crossing the midline, because crossing midline can occur with a floppy duodenum and does not exclude malrotation — Speaker 1
- 8:36A patient with low-lying ligament of Treitz who was observed subsequently presented with volvulus — Speaker 5
Cases discussed
- 0:316-year-old female with heterotaxy syndrome (right atrial isomerism), situs inversus, single ventricle anatomy, tricuspid atresia, failure to thrive, presenting for pre-operative cardiac evaluation
- 8:36Patient with low-lying ligament of Treitz who was observed and subsequently developed volvulus
Points of disagreement
- 5:39Whether to perform appendectomy during laparoscopy for heterotaxy with malrotation
- Speaker 2: Performs appendectomy, especially if appendix not in correct location or if cecum is floppy; uses inversion appendectomy technique
- Speaker 3: Does not remove appendix if it is in the correct location, noting that in situs inversus with malrotation the appendix is correctly positioned (double negative)
- 7:21Management of C-loop crossing midline with low-lying ligament of Treitz in normal child
- Speaker 1: Usually puts in laparoscope to evaluate
- Speaker 2: Would put in laparoscope
- Speaker 3: Does not do anything, previously observed these patients; all laparoscopies were negative, though reconsidering approach
- Speaker 6: Would just watch
Open questions
- What is the optimal management strategy for asymptomatic or minimally symptomatic malrotation in heterotaxy syndrome?
- Should appendectomy be routinely performed during laparoscopy for heterotaxy with malrotation?
- What is the appropriate management for C-loop crossing midline with low-lying ligament of Treitz in otherwise normal children?
- Can imaging reliably predict mesenteric base width in heterotaxy patients, or is laparoscopic assessment necessary?
