Intestinal obstruction due to internal herniation is rare. There is only 0.5–5.8% of incidence described in the available literature. In infancy, it is rarer. Internal herniation of Meckel's diverticulum through meso-appendix in an infant is an extremely rare emergency situation, and probably the first case to be reported in the literature.

| Introduction|| |
Intestinal obstruction in pediatric age group is a common emergency situation. It has a wide spectrum of pathology. Obstruction due to internal herniation is rare, and only 0.5–5.8% in an adult is reported in the literature. In pediatric age, it is sparse. Internal herniation through meso-appendix is uncommon, and only one case is reported in an adult until now. Internal herniation of Meckel's diverticulum through meso-appendix in infant is an extremely rare emergency situation. The uniqueness of this case hence prompts us to report in the literature.
| Case Report|| |
A 5-month-old male infant presented at emergency with an abdominal distention and constipation for 3 days. On examination, the patient was tachypoenic with a feeble pulse, dehydrated, and febrile. His urine output was scanty. Abdominal examination revealed the features of small bowel obstruction with visible bowel loops. The rectum was empty on digital rectal examination. Straight X-ray abdomen in erect posture showed the classical multiple air-fluid levels suggestive of small bowel obstruction [Figure 1]. Complete hemogram and serum electrolytes were normal except mild pallor. Immediately, after admission the patient was resuscitated with intravenous (IV) fluid, IV antibiotics. The patient was shifted to the operation theater for emergency exploration after initial stabilization. On exploration, it was found that Meckel's diverticulum herniated through a gap in the meso-appendix and adhered to the ascending colon, against which small bowel was twisted and obstructed [Figure 1]. The reduction of internal hernia was done after adhesiolysis [Figure 2]. Excision of Meckel's diverticulum along with adjacent ileum with end-to-end anastomoses along with the closure of the defect in the meso-appendix was done with absorbable polyglactin suture. Gut viability was checked, and the abdomen was closed. Postoperative period was uneventful, and the patient was discharged home on the 5th postoperative day. In a follow-up, the patient was doing well without any complications.

| Discussion|| |
Internal herniation (IH) is a rare cause of acute intestinal obstruction; approximately 0.5–5.8% is reported in the literature. It is defined as herniation of viscera through a normal or abnormal aperture within the peritoneal cavity. It usually presented with nonspecific symptoms such as pain abdomen, vomiting, etc., However, occasionally gangrenous changes may lead to the fatal outcome with very high mortality nearly 50%. The autopsy incidence of IH is 0.2–2%.
Congenital IH are classified according to their locations; (a) foramen of Winslow, (b) paraduodenal, (c) pericecal, (d) transmesenteric, (e) transomental, and (f) intersigmoid hernias. Paraduodenal and transmesenteric hernias are most commonly seen in children. Tang et al., suggested that transmesenteric hernia was the most common type in older children as well as in neonates, whereas paraduodenal hernia was commonly found in adults.
The first case of transmesenteric hernia was reported by Marsh. IH through meso-appendixin children has not been reported in the available literature until now. James et al. reported only a single-case of IH through meso-appendix in an 80-year-old female patient. Defects in the mesentery are commonly found near the ligament of Treitz or the ileocecal valve. They may be single or multiple and vary in size. Severity of the symptoms and progression of the disease depends on the size of the defect. A high index of suspicion is necessary to diagnose preoperatively. The diagnosis is usually established at the time of exploration.
Meckel's diverticulum (MD), the most common congenital anomaly of the gastrointestinal (GI) tract (2–3%), is an embryonic remnant of the vitelline duct and normally disappears by the 7th week of gestation. It is usually asymptomatic and often an incidental finding at laparotomy. Symptoms arise when there are associated complications such as GI bleeding, bowel obstruction, etc. IH of MD causing the bowel obstruction is a rare phenomenon and sparsely reported, but IH of MD through a congenital defect in meso-appendix in children is extremely rare.
Straight X-ray abdomen usually identifies the dilated bowel loops with air-fluid levels. Ultrasonography may suggest MD but often fails to detect IH. Computed tomography (CT) is usually the gold standard imaging modality for intestinal obstruction; however, identifying MD as the cause can be extremely difficult.
Multidetector CT (MDCT) with high spatial resolution and isotropic multiplanar reconstruction images have demonstrated MD included in hernias. The technetium-99 m pertechnetate scan in children has a sensitivity of 80–90%, a specificity of 95%, and an accuracy of 90%. If there is a complicated MD from the clinical or radiological suggestion, the Meckel's scan is the most accurate noninvasive investigation to perform.
| Conclusion|| |
Internal herniation of Meckel's diverticulum is a rare finding but should always be kept in mind during the treatment of small bowel obstruction in children. CT scan can be done preoperatively in a stable patient, but laparotomy often establishes the diagnosis. Early exploration after initial stabilization will help avoid potential life threatening complications.
