The Colorectal Quiz Episode 4
Suction rectal biopsy confirms the diagnosis of Hirschsprung's disease
clinical1:37 β†—
Two different operative approaches exist for Hirschsprung disease depending on whether transition zone is proximal and complicated versus distal
clinical1:37 β†—
For non-rectosigmoid transition zones, combined laparoscopy and transanal approach is preferred
clinicalAndrea Frischer5:03 β†—
Deep laparoscopic dissection into pelvis minimizes transanal work needed
clinicalAndrea Badillo5:56 β†—
Overstretching of sphincters during extensive transanal dissection is a morbidity that needs to be avoided
clinicalAndrea Badillo5:56 β†—
Transanal dissection should take under one hour in a primary pull-through
clinicalMarc Levitt6:33 β†—
Full thickness biopsy must include seromuscular side same size as mucosal side, cut as a square cube
clinicalAaron Garrison7:09 β†—
Port placement includes umbilical port, right lower and upper quadrant ports, with camera switched to right upper quadrant
clinicalMarc Levitt8:16 β†—
Should wait for frozen section before taking mesentery
clinicalAndrea Badillo9:30 β†—
Pathology must confirm ganglion cells and nerves less than 40 microns
clinicalAndrea Badillo10:00 β†—
Biopsy must include submucosa to avoid finding ganglion cells in seromuscular layer but hypertrophic nerves in submucosal layer
clinicalAndrea Frischer10:19 β†—
Mesenteric dissection should stay close to bowel wall, not deep in mesentery, to reduce bleeding
clinicalAndrea Frischer11:00 β†—
Must stay right on the bowel during dissection because too wide dissection of distal rectum causes incontinence and urinary retention from nerve injury
clinicalMarc Levitt11:42 β†—
Must preserve arcade along left colon and sigmoid to get enough distance to reach pelvis
clinicalAndrea Frischer12:26 β†—
For distal disease, can take just distal branches of IMA; for left colon involvement may need to take IMA to get reach
clinicalMarc Levitt12:35 β†—
Transanal dissection should identify dentate line and mark about one centimeter above into anal canal for division line
clinicalAndrea Badillo13:02 β†—
Preference is Swenson full thickness dissection in areolar plane which is bloodless, not submucosal dissection with cuff
opinionMarc Levitt14:12 β†—
If doing a cuff, make it very short (about one centimeter) and must split the cuff
clinicalMarc Levitt14:12 β†—
Patient can be kept supine with legs wrapped and fastened to ether screen for standard cases
clinicalAndrea Frischer15:04 β†—
Should go about five centimeters above biopsy site for safe margin
clinicalAndrea Frischer16:06 β†—
Tacking sutures on serosa to sidewall at three and six o'clock positions anchor bowel in place
clinicalAaron Garrison16:30 β†—
Reinforcement layer is critical to line up mucosa edge to mucosa edge
clinicalRod Gerardo17:00 β†—
Laparoscopic approach allows deep pelvic dissection minimizing transanal work and avoiding sphincter overstretching
clinicalAaron Garrison6:00 β†—
Transanal dissection in primary pull-through should take under one hour when adequate laparoscopic dissection is performed
clinicalJason Frischer6:33 β†—
Full-thickness biopsy should be a cube with seromuscular side matching mucosal side dimensions
clinicalAaron Garrison7:09 β†—
Frozen section must confirm ganglion cells and nerves less than 40 microns
clinicalAndrea Badillo10:00 β†—
Frozen section biopsy must include submucosa to avoid missing hypertrophic nerves in submucosal layer
clinicalMarc Levitt10:19 β†—
Mesenteric dissection should stay close to bowel wall to minimize bleeding and avoid injury to nerves
clinicalAaron Garrison11:00 β†—
Historical Swenson operations done through abdomen with wide distal rectal dissection caused incontinence and urinary retention from nerve injury
clinicalMarc Levitt11:42 β†—
Marginal arcade along left colon and sigmoid must be preserved to achieve adequate length for pelvic reach
clinicalAndrea Badillo12:26 β†—
