Intussusception is a frequent cause of intestinal obstruction in early childhood and most are idiopathic in origin. In a minority of cases a definite pathological lead point is identified by imaging studying or during surgery. As the pathologic lead point of intussusception, Meckel's diverticulum is the most common lesion. In symptomatic patients, 40~60% of Meckel's diverticulum contain ectopic tissue, with gastric mucosa being far the most common type. A few Meckel's diverticulum contain pancreatic tissue. Combined heterotopic pancreatic and gastric tissues in the Meckel's diverticulum especially causing intussusception is extremely rare. We report the case of 5-year-old girl with an intussusception caused by Meckel's diverticulum containing both heterotopic gastric and pancreatic tissues.

Objectives : The present study was investigated the effect and pathway of heterotopic electroacupuncture (EA) on pain induced by formalin in rats. Methods : Acupoints in the right forepaws, $HT_7$ and $PC_7$, were stimulated with 3 mA, 2 ms, and 10 Hz before subcutaneously formalin injection (5%, $50{\mu}l$) to the left hind paw. Moreover, it was investigated whether the dorsolateral funiculus (DLF), as known to the descending inhibition, mediates analgesia of the heterotopic EA, and an administration of naltrexone blocks the effect of EA. Results : In the immunohistochemistry of cFos-like protein (cFL), there were inhibitory effects of EA on the increased expression of cFL in the lumbar spinal dorsal horn neurons following formalin injection. Especially, EA inhibited the expression of cFL on the superficial laminae than that on the deep laminae at 1 hr after, but that on the deep laminae than that on the superficial laminae at 2 hr after. Also, EA suppressed the increased expression of nitric oxide (NO) and neuronal nitric oxide synthase (nNOS) in the lumbosacral spinal cord after formalin injection, but not Sham-EA. Suppressed expressions of cFL, NO and nNOS in the spinal cord were eliminated after transection of the ipsilateral DLF at $T_{10}{\sim}T_{11}$ levels. However, pretreatment of naltrexone could not prevent the suppressive expressions of cFL, NO and nNOS at the spinal cord. Conclusions : These results suggest that the analgesia of heterotopic EA may be modulated through the DLF constituting the descending inhibition.

Heterotopic ossification (HO) within the substance of the subscapularis tendon is a rare lesion which remains a poorly described condition with little known of the exact mechanisms involved. Furthermore, its clinical importance remains still unclear. To our knowledge, there are no studies present to data regarding HO within the substance of the subscapularis tendon, even with resultant isolated complete tear of the subscapularis tendon. Here we present a case of huge HO associated with unusual isolated complete tear of subscapularis tendon concomitant with tear of biceps long head tendon. After arthroscopic debridement for the complete tear site of biceps long head tendon, mini-open excision of the ossification and subscapularis repair with suture anchor fixation were performed. The patient showed complete recovery of strength and function of the subscapularis at subsequent 24 months follow up.

Heterotopic ossification (HO) is the formation of mature bone in soft tissue where bone normally does not exist. Although HO is among the most common complications after orthopedic surgery, it is not familiar to oral and maxillofacial surgeons. Here we report rare cases of HO. When a patient presents atypical osseous lesions, HO as well as similar lesions such as osteoma, osteochondroma should be considered in the provisional diagnosis. Three-dimensional reconstruction of preoperative computerized tomography imaging improves surgical success.

Heterotopic pancreas (HP) is defined as pancreatic tissue lacking anatomic and vascular continuity with the main body of the pancreas. Most are asymptomatic, but can cause ulcer, bleeding, intussusception, and mechanical obstruction. Herein, we presented one case of HP presented as duodenal tumor causing duodenal obstruction. A 7-year-old girl visited the emergency room for abdominal pain with vomiting for 24 hours. Computed tomography and upper gastrointestinal series revealed a polypoid mass with short stalk in the 2nd portion of duodenum. We attempted an endoscopic removal. However, the lumen was nearly obstructed by the mass and the stalk was too broad and hard to excise. The mass was surgically removed via duodenotomy. It was confirmed as a HP with ductal and acini components (type 2 by Heinrich classification). Postoperatively, the patient has been well without any complication and recurrence.

Diagnosis of heterotopic pregnancy could be delayed because of insufficient clinical symptoms. Many clinician mistook the symptoms associated with ectopic pregnancy for the symptoms of complicated normal intrauterine pregnancy. The incidence of heterotopic pregnancies has been increased because of the use of various ovulation induction and assisted reproductive technologies. We experienced a case of bilateral tubal pregnancies and intrauterine twin pregnancy in polycystic ovary syndrome woman conceived after ovulation induction by clomiphene citrate. We report this case with a brief review of the literatures.

Purpose: Resection remains the most reliable treatment for established heterotopic ossification, despite questions regarding its effectiveness due to the potential for complications. This study evaluated the clinical outcomes and complications of neurogenic heterotopic ossification (NHO) resection in stroke patients' ankylosed hips. Materials and Methods: We retrospectively analyzed nine hip NHO resections performed on seven patients from 2010 to 2018. The pre- and postoperative range of motion of the operated hip were compared. Analysis of postoperative complications, including infection, recurrence, iatrogenic fracture, and neurovascular injury was performed. Results: The mean operative time was 132.78±21.08 minutes, with a mean hemoglobin drop of 3.06±0.82 g/dL within the first postoperative week. The mean duration of postoperative follow-up was 52.08±28.72 months for all patients. Postoperative range of motion showed improvement from preoperative. Flexion and external rotation (mean, 58.89±30.60° and 16.67±18.03°, respectively) showed the greatest gain of motion of the operated hip joint. Postoperative infections resolved in two cases through surgical debridement, and one case required conversion to total hip arthroplasty due to instability. There were no recurrences, iatrogenic fractures, or neurovascular injuries. Conclusion: Resection is a beneficial intervention for restoring the functional range of motion of the hip in order to improve the quality of life for patients with NHO and neurological disorders. We recommend performance of a minimal resection to achieve a targeted functional arc of motion in order to minimize the risk of postoperative complications.

The incidence of heterotopic ossification (HO) was reported to be higher in combat-injured patients than in civilian trauma patients. HO is often considered a possible cause of residual limbs pain in amputee. Here, we report the case of a 21-year-old male, who underwent a traumatic right transfemoral and left transtibial amputation with two segments of painful HO around his left amputation site. We report the effect of extracorporeal shock wave therapy (ESWT) on size and pain associated with HO. After ESWT, the visual analog scale score decreased from 5~6 to 0~1 and the size of two masses decreased from 13.1 × 6.7 mm and 12.5 mm to 11.9 × 4.7 mm and 12.2 mm, respectively. To the best of our knowledge, this is the first case that has reported on the treatment of HO using ESWT for a traumatic transtibial amputation patient. The case suggests that ESWT could serve as a complementary treatment for HO in traumatic amputation patient.
