Summary

Intussusception is the primary cause of intestinal obstruction in children aged 3 months to 5 years, leading to significant morbidity and mortality rates. Most cases involve the ileocolic region and can often be resolved through air enema, with a success rate of up to 95%. Surgical intervention becomes necessary if pneumatic reduction fails or is not recommended. Traditionally, manual reduction required a large incision on the right side of the abdomen. However, the advancement of minimally invasive techniques, such as the laparoscopic approach (LAP), has become increasingly popular for managing intussusception. LAP offers benefits such as reduced surgical trauma and shorter operative times compared to open procedures. Nevertheless, the adoption of LAP remains controversial due to challenges like limited working space in children and variability in the affected bowel segment. This study aims to investigate the safety and feasibility of LAP and mini-open reduction (MOR) techniques in treating idiopathic intussusception in pediatric patients.

Detailed description

Intussusception, the leading cause of intestinal obstruction in children aged 3 months to 5 years, significantly impacts morbidity and mortality rates. Most cases involve the ileocolic region and are typically amenable to resolution via air enema, achieving success rates of up to 95%. Surgical intervention becomes necessary in cases where pneumatic reduction fails or is contraindicated. Historically, the manual reduction required a substantial right-sided transverse incision. However, the advancement of minimally invasive approaches in pediatric surgery, particularly the laparoscopic approach (LAP), has gained traction in managing intussusception. LAP offers the advantages of decreased surgical trauma and shorter operative durations compared to open procedures. Nevertheless, the adoption of laparoscopic intervention for intussusception remains contentious due to challenges such as limited operative space in pediatric patients and variability in the affected bowel segment, impeding widespread acceptance. This study aims to investigate the safety and feasibility of laparoscopic (LAP) and mini-open reduction (MOR) techniques in managing idiopathic intussusception in pediatric patients.

Interventions

Type	Name	Description
PROCEDURE	Laparoscopic reduction	A 1cm longitudinal transumbilical incision was made to insert a 5mm trocar for laparoscope placement. CO2 was injected at 10mmHg and a flow rate of 3L. Two 5-mm working trocars were inserted in the lower right and left abdomen under direct visualization, along with two grasping forceps. The ascending colon was manipulated to locate the intussusception mass. Atraumatic graspers were alternately utilized on the ascending colon to mobilize the intussusceptum, pushing it downward towards the cecum. The first visible part of the terminal ileum was grasped and pulled outward and downward, along with its mesentery, using the right grasper, while the left grasper pulled the intussusceptum's neck in the opposite direction. If resistance was encountered, the terminal ileum could be held with the left hand while the right grasper widened the intussusceptum's neck. After reduction, the intestines were examined for necrosis and possible lead points, followed by routine appendectomy and ileopexy.
PROCEDURE	Transumbilical mini-open reduction	If laparoscopic reduction alone was unsuccessful or if bowel resection was required, the intussusceptum was fixed with grasping forceps and brought to the umbilicus for MOR. A 2cm transumbilical incision was created, and a skin retractor was inserted. The underlying fascia was longitudinally extended upward and downward along the linea alba. Upon division of the peritoneum, the actual opening could be expanded up to 5cm, while maintaining the skin incision at 2cm. If the initial incision site proved insufficient for exploration, lateral division of the rectus muscle around the umbilicus on both sides could be performed without cutting the skin, thereby enlarging the surgical field. Manual reduction of the intussusceptum was subsequently carried out, along with bowel resection and anastomosis as indicated.
