Insights
This study analyzed 40 years of intestinal atresia cases, finding that improved neonatal surgical techniques and appropriate procedures significantly reduced mortality rates. A new long-oblique anastomosis technique is recommended for disproportional intestinal loops.
Area of Science:
- Pediatric Surgery
- Neonatal Care
- Gastrointestinal Surgery
Background:
- Intestinal atresia is a congenital condition requiring surgical intervention.
- Over 40 years, treatment strategies and outcomes for intestinal atresia have evolved.
- Congenital small intestine atresia presents significant challenges in neonatal surgical care.
Purpose of the Study:
- To analyze a 40-year experience with intestinal atresia.
- To introduce and evaluate a novel long-oblique anastomosis technique for disproportional intestinal loops.
- To identify factors influencing survival rates in congenital intestinal atresia.
Main Methods:
- Retrospective analysis of 449 congenital small intestine atresia cases.
- Classification of atresia based on embryopathology (high, middle, low groups).
- Stratification of cases by treatment era (1956-1969, 1970-1985, 1986-1996) to assess evolving care.
Main Results:
- The ileo-jejunal atresia group exhibited the highest mortality (47.6%).
- Overall mortality decreased significantly over the study period, from 64.7% to 18.6%.
- Zero hospital deaths were recorded in the most recent years, indicating improved outcomes.
Conclusions:
- Improved neonatal surgical techniques are crucial for reducing intestinal atresia mortality.
- Selecting surgical procedures aligned with embryopathology is essential for better outcomes.
- The long-oblique anastomosis technique is a viable option for managing disproportional intestinal loops, particularly in specific clinical settings.
Objective:
To analyze the 40 years' experience of intestinal atresia and to introduce a new design of long-oblique anastomosis for disproportional loops of the intestine.
Methods:
A total of 449 cases of congenital atresia of the small intestine were classified into three groups according to the embryopathology: high group (145 cases), including duodenal and high jejunal atresia; middle group (288), including ileo-jejunal atresia; and low group (16), including terminal ileal atresia. To analyze the survival rate and mode of treatment, we assigned the cases into 3 groups according to the year of admission: 1) 1956-1969 (173 cases), under the general pediatric surgical care; 2) 1970-1985 (147), under the specialty neonatal surgical care; and 3) 1986-1996 (129), with additional use of total parenteral nutrition.
Results:
The ileojejunal atresia group (middle group) had the highest mortality rate (47.6%). The overall mortality rate decreased as the time went by, dropping from 64.7% in the early years down to 18.6% in the recent years, and no hospital death occurred in the recent couple of years.
Conclusion:
Besides the improvement of neonatal surgical techniques, selecting a proper surgical procedure according to the embryopathology is essential to the reduction of mortality. The long-oblique anastomosis is particularly acceptable in China at present for marked disproportional loops.
