In his classic textbook Pediatric Surgery, Dr. Orvar Swenson – who is eponymously
associated with one of the classic surgical treatments for Hirschsprung’s Disease – described this
condition as follows:

The diagnosis of Hirschsprung’s disease requires surgery in all cases. The classic surgical
approach consisted of a multiple stage procedure. This includes colostomy in the newborn period,
followed by a definitive pull-through operation after the child weighed over 10 kg. There are three
viable options for the definitive pull-through procedure that are currently used (the Swenson,
Soave, and Duhamel procedure). Although individual surgeons may advocate one procedure over
another, studies have demonstrated that the outcome after each type of operation is similar. For
each of these procedures, the principles of treatment include
A. Confirming the location in the bowel where the transition zone between ganglionic and
aganglionic bowel exists
B. Resecting the proximal ganglionic segment of the bowel
C. Performing an anastomosis of ganglionated bowel to either the anus or a cuff of rectal mucosa

esophageal varices

The following are components of the primary survey of a burn patient EXCEPT
A. TOI
B. POI
C. Airway patency
D. Co-morbidities
E. Total surface area of burn
```
D?
According to the Topnotch reviewer, which itself is based on Schwartz, airway patency and
determination of total surface area of the burn are part of the initial management of burn patients.
They should also be treated as trauma patients, hence the typical primary survey including DOI,
TOI, POI, MOI should be accomplished. If by co-morbidities we mean medical conditions such as
hypertension and diabetes, these are not part of the primary survey. If by co-morbidities we mean
other injuries sustained in addition to the burn, then it should be part of the primary survey.
