Diverticulum was found by laparoscopic exploration The diverticulum was raised through a small incision at the umbilicus and anastomosed with intestinal resection Meckel’s diverticulum (MD) is caused by abnormal development of the vitelline duct during embryonic period, and incomplete degeneration of the ileocecal end of the vitelline duct results in the formation of Meckel’s diverticulum, which is a common congenital anomaly of the small bowel and is located in the contralateral edge of the mesentery within 100 cm of the terminal ileum. There are various types of diverticula, including those with narrow and elongated base and those with wide base. Some Meckel’s diverticula are connected to the umbilicus by cords, and most of Meckel’s diverticula are supplied by the wall of the intestinal canal, while a few diverticula are supplied by their own mesentery. Although the incidence of Meckel’s diverticulum is high and most of them are asymptomatic, various complications can occur in about 15% to 25% under the influence of multiple factors. Complications are related to the presence of ectopic gastric mucosa, pancreatic tissue and duodenal mucosa in the diverticulum, mainly bleeding, inflammation diverticulum perforation and intestinal obstruction. The structure of Meckel’s diverticulum is the same as that of normal intestinal tube, but the muscular layer is thinner, and some diverticula have mesenchymal gastric mucosa and pancreatic tissues within the diverticulum, and the gastric mucosa can secrete hydrochloric acid and pepsin, which constantly stimulate the mucosa of the diverticulum, and ulceration, bleeding, or even perforation occurs. Ectopic pancreatic tissue is the main cause of diverticulitis. Bleeding is one of the most common complications of Meckel’s diverticulum, with a large amount of bleeding, hemoglobin often drops to 70-80 g/L within a short period of time after bleeding, and hypovolemic changes occur. Surgery is the only effective treatment. The cause of bleeding is related to the secretion of gastrin by the G cells of the ectopic gastric mucosa, which stimulates the mural cells to secrete hydrochloric acid in large quantities, corroding and digesting the mucosa and blood vessels of the diverticulum. Pediatric peritonitis must be expanded if the appendix is normal on exploration to avoid missed diagnosis of Meckel’s diverticulitis complicating perforation. Intestinal obstruction in Meckel’s diverticulum occurs for many reasons, the main ones being intestinal torsion, compression, trocars, and internal hernias. Diverticula with comorbidities or accidentally found intraoperatively should be treated surgically with resection of the lesion and involved bowel, and laparoscopic-assisted exploration and resection becomes the preferred procedure. Laparoscopic appendectomy with septic perforation of the appendix and concomitant discovery of Meckel’s diverticulum Meckel’s diverticulum was raised through an umbilical incision, and enterotomy anastomosis was performed Postoperative pathology, with a diverticulum lined with gastric mucosa, which was the cause of the hemorrhage Appearance of the abdomen after the minimally invasive procedure, with no scar visible
