Item Meckel Diverticulum in Children: Evaluation of Macroscopic Appearance for Guidance in Subsequent Surgery(2016) Gezer, Hasan Ozkan; Temiz, Abdulkerim; Ince, Emine; Ezer, Semire Serin; Hasbay, Bermal; Hicsonmez, Akgun; 0000-0002-4635-2613; 0000-0001-8789-6003; 0000-0002-9597-3264; 26435520; J-3197-2013; A-4719-2018; AAJ-9529-2021Background: The treatment of incidentally encountered asymptomatic Meckel diverticulum(MD) is controversial. We evaluated whether the macroscopic appearance correlates with clinical features, histopathological findings, future complications, and management decisions. Methods: Patients who underwent MD resection at a single institution from 2000 to 2012 were retrospectively analyzed in terms of age, sex, clinical features, laboratory data, perioperative findings (diverticulum length, diameter, depth, thickening, and height-to diameter ratio [HDR]), pathology, and postoperative follow-up. Results: Fifty children were enrolled. Sixteen percent of the resected MDs were found incidentally. Of 42 complicated MDs, 17 (40%) were long (HDR >= 2), 14 (33%) were thickened, and 29 (70%) exhibited base widening. Histopathologically, ectopic mucosa was found in 32 (64%) of all MDs and in 5 (62%) of incidentally removed MDs. There was no statistical difference between the macroscopic appearance and clinical signs, sex, or presence of ectopic tissue based on palpation. Conclusion: The macroscopic appearance of MD does not indicate the presence or absence of HGM and cannot be used to guide subsequent surgery. Additionally, 40% of symptomatic patients in our study had life-threatening complications requiring prompt fluid resuscitation. We consider that incidentally detected MD should be removed regardless of its macroscopic appearance. (C) 2016 Elsevier Inc.

Methods: A total of 55 Langerhans cell histiocytosis patients, diagnosed between the year 2006 and October 2020 in our department were included in the study. The patients were evaluated in terms of age, gender, tumor localization, risk groups, treatment modalities, recurrence, and outcome of the disease. Results: Twenty-three out of 55 patients were children and 32 were adults. The ages of the patients were between 7 months and 72 years. Thirty-seven of the cases were male and 18 were female. The most common clinical complaint in both groups was pain and swelling. The duration between the onset of the patient complaints and admission to the hospital varies between 7 days-12 months in children, and 10 days-23 years in adults. Forty-three of the cases had single organ involvement and 12 had multiorgan involvement. The most frequently affected organ in both groups was bone. Forty of the 55 patients had follow-up data and the treatment modalities are as follows: Nine patients radiotherapy, 8 patients chemotherapy+steroid, 7 patients chemotherapy, 2 patients chemotherapy+radiotherapy+steroid, 1 patient steroid, 2 patients chemotherapy+radiotherapy. Eleven patients were followed up without additional treatment after surgery. Median follow-up from the time of biopsy was 45.9 months in children and 41.9 months in adults. Conclusions: As a result, diagnosis requires a high degree of suspicion and final diagnosis is based on the histological examination of the lesions and biopsies.
