    Abstract:
    PURPOSE/BACKGROUND: Meckel's diverticulum (MD) is one of the most common congenital malformations of gastrointestinal tract in children. However, the nonspecific clinical manifestations of MD often cause a diagnostic as well as therapeutic challenge to pediatric surgeon. This study aimed to review our experience in managing this disease while evaluating the management strategies. METHODS: We retrospectively analyzed the clinical data of all patients diagnosed with MD admitted to our center between January 2010 and December 2015. Factors documented including demographic criteria, clinical manifestations, preoperative examinations, surgical methods, histopathological characteristics, postoperative complications, and outcomes. RESULTS: The patients included 210 males and 76 females, aged from 1day to 15years. In fifty three patients, the MD was an incidental finding at laparotomy or laparoscopy. The remaining 233 patients were symptomatic and presented with various clinical features. Ninety nine patients presented with episodes of bleeding per rectum or melena. Fifty six patients demonstrated symptoms of diverticulitis or perforated MD. Forty patients were diagnosed as intestinal obstruction, and 35 patients with intussusception requiring surgical reduction. Two cases of Littre hernia and one case of foreign body trapped in MD were also observed in this group. Six patients misdiagnosed as appendicitis at another institution were reoperated in our department. Among the 99 patients with bleeding per rectum, 78 underwent a Tc-99m scan that showed a positive tracer in 55 patients and negative in 23. All patients underwent resection of the diverticulum, except for 2 cases of postponed resection. Histology revealed ectopic gastric mucosa or ectopic pancreatic tissue in 154 patients; significant differences were observed between the symptomatic group and the accidentally found group. One patient died of peritonitis and sepsis postoperatively; one case of anastomotic leak and one case of adhesive intestinal obstruction were reoperated. CONCLUSION: Meckel's diverticulum has various clinical presentations and it is difficult to make a precise diagnosis preoperatively. It is necessary to maintain a high suspicion of MD in the pediatric age group with symptoms of abdominal pain, gastrointestinal hemorrhage or intestinal obstruction. Heterotopic tissue is the main cause of complicated diverticulum, and it is safe and feasible to remove the incidentally found MD. Laparoscopy should become the first choice of methods in diagnosis and treatment of MD. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level IV.
