Heterotopic pancreas (HP) is rarely recognized during surgery. Many reports concerning this anomaly are simple case reports. We herein review our experiences with HP. We retrospectively investigated cases of HP from April 1975 to September 2006. We discussed the frequencies in the laparotomized patients, and patient's age, gender, operative indication, location of HP, post-operative diagnosis and pathology. A total of 12 patients with HP, 3 boys and 9 girls, aged 1 day to 10 years of age were investigated. Ten patients had one pattern of HP and the remaining two had more than one. The locations of the HP were as follows: Meckel's diverticulum, 4; stomach, 3; duodenum, 3; jejunum, 3; and ileum, 2. Only in one patient HP had caused an intussusception. The remaining 11 cases were identified incidentally during the operation. In 11 of 12 patients, HP was removed without post-operative complications. Classification of pathologies according to Heinrich is as follows: type I, 4; type II, 4; type III, 2 and unknown, 2. Patients with HP are usually asymptomatic. However, HP caused an intussusception in our series. Incidental HPs should be removed whenever identified during laparotomy.

Adhesive strapping promoted early spontaneous umbilical hernia closure compared with observation alone, regardless of the diameter of the hernia orifice. Adhesive strapping is an effective alternative to surgery and observation.

We present an unusual case of acute abdomen caused by torsion of an accessory spleen with situs inversus in a child. A three-year-old girl was admitted to our hospital with an 11-day history of right flank pain with fever. Her medical history revealed an operation of coarctation of the aorta with situs inversus at one month of age. Physical examination revealed a right flank mass and tenderness. A contrast-enhanced CT scan showed a normally enhanced small spleen in the right upper quadrant and a 7.0×6.0×3.5 cm, hypodense, marginal enhancing mass in the right midabdomen adjacent to the intestine. An emergency laparotomy was decided upon with a preoperative diagnosis as an acute abdomen. During surgery, a mass was found under the greater omentum and two accessory spleens of 1.5 cm in diameter were found surrounding the main spleen. Several loops of bowel were adherent to the mass. The loops of bowel were dissected away. A pediculated congested mass was observed as an accessory spleen emerging from the greater omentum. The mass was twisted on its vascular pedicle and strangulated. The necrotic mass was removed and the postoperative recovery was uneventful. Though torsion of an accessory spleen is extremely rare, it should be considered in the differential diagnosis of acute abdomen in childhood.

We concluded that hereditary predisposition, such as anatomical basis, may be considered as an etiological factor in many cases of idiopathic intussusception. In these predisposed families, if they have inducements such as viral infections as the acquired agents, intussusception will occur very easily.
