Introduction: Our aim was to highlight the characteristics of pediatric Meckel's diverticulum with a special focus on its complications.
Methods: We report a group of seven patients with Meckel's diverticulum and its resection from the Department of Pediatric Surgery between 2012 and 2017. We reviewed all patient records, clinical presentation, and intraoperative findings. The diagnosis was confirmed by surgery and pathology. For a systematic literature review, we used PubMed, Medline and Google Scholar search engines to locate articles containing terms such as Meckel's diverticulum, children, pediatric, complications and symptomatic. We included article reporting on case series in English and German on pediatric patients only.
Results: All included patients (n = 7) were symptomatic. Some patients showed isolated symptoms, and others presented with a combination of symptoms that consisted of abdominal pain, bloody stool or vomiting. The median age of our seven cases was 3.5 years, including 4 male and 3 female patients. Intestinal obstruction was the most common complication; it was seen in 5 out of 7 patients (intussusception in 4 cases, volvulus in 1 case). Ectopic gastric tissue was identified in 3 cases, and inclusion of pancreatic tissue was observed in 1 case. The literature review identified 8 articles for a total of 641 patients aged between 1 day and 17 years and a male:female ratio of 2.6:1. From this group, 528 patients showed clinical symptoms related to Meckel's diverticulum. The most common symptom was abdominal pain and bloody stool. The most common surgical finding in symptomatic patients was intestinal obstruction (41%), followed by intestinal hemorrhage (34%). Complications such as perforation (10%) and diverticulitis (13%) were less frequently reported. Heterotopic tissue was confirmed on histopathology in 53% of all patients enclosing gastric, pancreatic, and both gastric and pancreatic mucosae. In one case, large intestine tissue could be found. Overall, one death was reported.
Conclusion: The presented case series and literature review found similar clinical presentations and complications of Meckel's diverticulum in children. Intestinal obstruction and bleeding are more frequent than inflammation in pediatric Meckel's diverticulum. Bowel obstruction is the leading cause for complicated Meckel's diverticulum in patients younger than 12 years.
Ziel der Studie: Die akute alkoholinduzierte Fettleber stellt das erste Stadium alkoholischer Leberer-krankungen dar. Bereits eine akute Alkoholintoxikation führt zu einer signifikanten Ak-kumulation von Fett in den Hepatozyten. Trotz verbesserter serologischer und bildge-bender Diagnoseverfahren ist die Leberbiopsie nach wie vor der Goldstandard zur Di-agnose einer Fettleber. Mögliche Komplikationen als invasives Verfahren, Stichproben-fehler sowie eine geringe Sensitivität im Bereich geringgradiger Verfettung sind die größten Nachteile der Leberbiopsie. Ziel dieser Studie war es, mit Hilfe der 1H-Magnetresonzspektroskopie eine akute alkoholinduzierte Fettleber zu diagnostizieren und quantitativ zu beurteilen. Um die Korrelation zwischen spektroskopisch gemesse-nem Leberfettgehalt und histologischer, biochemischer sowie laborchemischer Analyse zu bestimmen, wurde eine alkoholinduzierte Fettleber im Tiermodell verwendet.
Methodik: In 20 Lewis-Ratten wurde eine alkoholische Fettleber mittels gastraler Ethanol-Applikation induziert; 10 Ratten dienten als Kontrolle. Der intrahepatische Fettgehalt wurde mittels 1H-MRS (3.0 T) als prozentuales Verhältnis zwischen Lipid- und Was-ser-Peak berechnet. Fettgehalt sowie Triglyceride wurden nach Entnahme der Leber histologisch und biochemisch (nach FOLCH) bestimmt. Um spezifische Leberenzyme zu untersuchen, wurde Blut aus dem orbitalen Venenplexus entnommen.
Ergebnisse: In allen 20 Tieren konnte nach Ethanolapplikation eine Leberverfettung mittels 1H-MRS nachgewiesen werden. Histologisch zeigten 16 Tiere eine Fettleber. Ebenso zeigte sich nach Ethanolgabe und folgender biochemischer Analyse im Durschnitt eine Erhö-hung des Triglyceridgehalts, welcher einer Leberverfettung entsprach. Es fanden sich statistisch signifikante Korrelationen zwischen der histologisch bestimmten intrahepati-schen Verfettung und dem spektroskopisch gemessenen Fettgehalt (Pearson-Korrelationskoeffizient r = 0.90, p < 0.01) sowie zwischen der biochemischen Analyse nach FOLCH und 1H-MRS (r = 0.97, p < 0.01). Ebenso zeigte sich eine positive signifi-kante Korrelation zwischen spektroskopisch gemessener Leberverfettung und den Le-berparametern AST (r = 0.91, p < 0.05) und ALT (r = 0.84, p < 0.05).
Schlussfolgerung: Es konnte gezeigt werden, dass bereits geringgradige intrahepatische Verfettungen prä-zise quantitativ mittels 3.0 T-Protonen-MR-Spektroskopie darstellbar sind. Somit kann die Methode – bei Beachtung geeigneter Grenzwerte histologischer Messungen – als verlässliche diagnostische Alternative in Betracht gezogen werden. Bereits 48 Stunden nach Alkoholintoxikation ist mittels 1H-MRS eine exakte Differenzierung gesunder und pathologischer Lebern möglich – entscheidend vor allem im Rahmen einer Prätrans-plantationsdiagnostik bei Verdacht auf eine akute Fettleber. Darüber hinaus ist die 1H-MRS anderen bildgebenden Verfahren wie Ultraschall, CT und MRT in der genauen Quantifizierung intrahepatischen Fettgehalts überlegen. Der Einsatz erscheint auch in der Diagnostik und Verlaufskontrolle alkoholischer Lebererkrankungen in Zukunft sinnvoll. Kommende Untersuchung sollten an einem größeren Probandenkollektiv durchgeführt werden, um den Stellewert der 1H-MRS zu unterstreichen.
Purpose: The COVID-19 pandemic has led to an unprecedented expansion of telemedicine services worldwide. This study aimed to explore the practice of telemedicine in Pediatric Surgery in Germany, the impact of the pandemic on its development and parents’ and surgeons’ experiences with telemedicine.
Methods: The study is a cross-sectional analysis using three surveys between 6/2020 and 10/2020: (1) all Pediatric Surgery departments of Germany reported whether they provide telemedicine services. (2) Members of the German Society of Pediatric Surgery and (3) families who participated in an outpatient visit by telephone or video with the Department of Pediatric Surgery and Pediatric Urology of the University Hospital Frankfurt completed an anonymous survey on their experience with telemedicine.
Results: 21% of the Pediatric Surgery departments in Germany provided telemedicine, of which 57% started due to the pandemic. The lack of physical examination and face-to-face contact seem to be the major limitations to surgeons and parents. 48% of the parents answered that telemedicine is equal to or better than traditional appointments, while 33% thought that telemedicine is worse.
Conclusions: This study shows that families and doctors alike have had positive experiences with telemedicine and most will continue to use this format after the pandemic.
Background: Duodenal obstruction is a rare cause of congenital bowel obstruction. Prenatal ultrasound could be suggestive of duodenal atresia if polyhydramnios and the double bubble sign are visible. Prenatal diagnosis should prompt respective prenatal care, including surgery. The aim of this study was to investigate the rate and importance of prenatally diagnosed duodenal obstruction, comparing incomplete and complete duodenal obstruction. Methods: A retrospective, single-center study was performed using data from patients operated on for duodenal obstruction between 2004 and 2019. Prenatal ultrasound findings were obtained from maternal logbooks and directly from the investigating obstetricians. Postnatal data were obtained from electronic charts, including imaging, operative notes and follow-up. Results: A total of 33/64 parents of respective patients agreed to provide information on prenatal diagnostics. In total, 11/15 patients with complete duodenal obstruction and 0/18 patients with incomplete duodenal obstruction showed typical prenatal features. Prenatal diagnosis prompted immediate surgical treatment after birth. Conclusion: Prenatal diagnosis of congenital duodenal obstruction is only achievable in cases of complete congenital duodenal obstruction by sonographic detection of the pathognomonic double bubble sign. Patients with incomplete duodenal obstruction showed no sign of duodenal obstruction on prenatal scans and thus were diagnosed and treated later.
We report a case of a 2-day-old neonate with bilious vomiting and abdominal distension. A small bowel obstruction with ileal perforation due to a misplaced clamping of the umbilical cord was apparent before laparotomy. This complication was a sequala after clamping the cord too close to the abdominal wall in a case where there was a hernia into the cord with intestinal content. A herniation of abdominal contents due to an omphalocele minor or a hernia must be taken into consideration during the inspection of the umbilical cord before clamping.
