Insights
This study introduces a novel duodenal lengthening technique for children with short bowel syndrome (SBS), improving intestinal function. The procedure successfully increased absorptive surface area, reducing reliance on parenteral nutrition.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Intestinal Rehabilitation
Background:
- Duodenal dilatation in short bowel syndrome (SBS) leads to dismotility and bacterial overgrowth.
- The duodenum's critical anatomy has historically precluded lengthening procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of a novel duodenal lengthening technique in pediatric SBS patients.
- To assess the impact of duodenal lengthening on parenteral nutrition dependence.
Main Methods:
- A novel surgical approach combining duodenal lengthening with modified serial transverse enteroplasty (STEP) was performed on three children with SBS.
- Duodenal lengthening utilized sequential endoscopic stapler applications to preserve critical structures.
- The extent of duodenal lengthening varied, representing 17-83% of total enteroplasty firings.
Main Results:
- No surgical complications were observed; one patient experienced transient D-lactic acidosis.
- Two patients achieved full weaning from parenteral nutrition within 12 months.
- The third patient demonstrated a 60% reduction in parenteral calorie requirements.
Conclusions:
- Duodenal lengthening is an effective strategy for increasing duodenal absorptive surface area in SBS.
- This technique offers a viable option for managing even extreme cases of short bowel syndrome.
Unlabelled:
Although duodenal dilatation occurs in children with short bowel syndrome (SBS) facilitating dismotility and bacterial overgrowth, the duodenum has been an untouchable intestinal segment for lengthening procedures owing to its close relationship with bilio-pancreatic structures and blood supply shared with the pancreas. Three children (age range, 0.5-7 years) with SBS and dilated duodenum underwent a novel surgical procedure of duodenal lengthening combined with a technical modification of serial transverse enteroplasty (STEP). Pre-STEP, jejunum length was 5, 35 and 45cm, respectively. Duodenal lengthening was performed with sequential transverse applications of an endoscopic stapler on the anterior and posterior wall of the duodenum to avoid bilio-pancreatic structure injury. Two patients underwent 3 duodenal firings (stapler of 35mm) and the third 5 firings (stapler of 45mm). Duodenal firings were 17%, 21% and 83% of the total firings.
Results:
No surgical complications occurred. One patient developed transient episodes of D-lactic acidosis. Two patients (5 and 45cm) were weaned off parenteral nutrition at 12months post-surgery and the remaining patient´s (35cm) parenteral calorie requirements have decreased by 60%.
Conclusion:
Duodenal lengthening is effective since it tailors and increases the absorptive surface of the duodenum, even in cases of extreme SBS.

01:15Small Intestine
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...
