Our aim was to highlight the characteristics of pediatric Meckel's diverticulum with a special focus on its complications. 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. All included patients ( = 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. 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.

BACKGROUND
In central Africa, millions of individuals infected with have received the anthelminthic drug ivermectin (IVM) as part of mass drug administration (MDA) campaigns targeting onchocerciasis control or elimination. Nonetheless, the parasitological surveys that are occasionally conducted to evaluate the impact of IVM treatments on do not include an assessment of the extra benefits of those MDA campaigns on .
METHODS
We conducted a systematic review of trials on the effect of a single standard (150-200 μg/kg) dose of IVM on microfilarial density (MFD). The dynamics of MFD over 365 days of treatment were described using multilevel regression and latent class modeling.
RESULTS
IVM brings about a rapid, dramatic, and sustained decrease, with reduction rates of 60%, 75%, 85%, and 90% on day 1 (D1), D2, D7, and D365, respectively. At D365, no participants (0/238) with an initial MFD of <20 000 microfilariae (mf)/mL were at risk of postivermectin severe adverse events, and only 1/57 individuals with an initial MFD of ≥20 000 mf/mL presented with an MFD above this value. The main predictor of post-treatment MFD was the pretreatment value, but this post-treatment value varied little between D8 and D365 regardless of the pretreatment level.
CONCLUSIONS
A single dose of IVM is very effective at substantially reducing MFD for at least a year, irrespective of the initial level of parasitemia. Individuals treated with IVM are probably not any more at risk of severe adverse events when retreated 1 year later.

World Journal of Pediatrics : WJP Jun 2019Gastric volvulus (GV) in children is a rare condition. This study reviewed management and outcomes of GV in the pediatric population.
BACKGROUND
Gastric volvulus (GV) in children is a rare condition. This study reviewed management and outcomes of GV in the pediatric population.
METHODS
MEDLINE/PubMed, Embase, and Google Scholar databases were searched for studies in English regarding GV in patients < 18 years old between 2008 and 2017, selected by two reviewers. Results were presented as percentages and medians. Fisher's exact test was used to evaluate categorical variables, and Bonferroni correction was applied for multiple comparisons.
RESULTS
Ninety-seven papers with 125 patients were included. The median age was 24 months, with slightly female preponderance. Vomiting was the most common symptom and acute presentation occurred in the majority of cases. History of previous surgery/abdominal trauma was described in 12 and 3 children, respectively. Radiology was diagnostic for GV in most cases. The initial management was surgical in the majority of cases, with most of them including gastropexy, gastrostomy, or gastric resection. Mesenteroaxial GV was associated with acute presentation (P = 0.004) and the latter with ischemia (P < 0.01). Complications occurred in 23 (18.9%) children, esophageal stenosis being the most common. There were eight (6.4%) deaths, and only one recurrence 6 months after endoscopic management. The median follow-up period was 12 months. The inclusion of only case reports/case series, the incomplete reporting from papers, and the short follow-up were limitations of the study.
CONCLUSIONS
GV occurs at a median age of 24 months and requires high suspicion and prompt management, as mortality is considerable. The preferred surgical approach for GV includes variations of gastropexy. Esophageal stenosis is the most common morbidity post-GV management.

Comparative Study
BACKGROUND
Laparoscopic colectomy represents a safe, effective and well-established procedure for both benign and malignant colic disease. Transanal anastomosis (TA) with a circular stapler is the most commonly performed anastomotic technique in laparoscopic left hemicolectomy (LLH). We report our experience with side-to-side anastomosis (STSA) and side-to-end anastomosis (STEA) in selected patients with both emergency and elective LLH.
METHODS
A systematic review of the PubMed database was performed on recent studies that compared different anastomotic techniques after LLH. We collected internal data from June 2014 to July 2018 and compared our experience with the literature. The primary outcome was the anastomotic complication rate.
RESULTS
During the observation period, 158 patients underwent left hemicolectomy (LH). One-hundred-nineteen patients had malignant disease; 36 underwent surgery for complicated diverticular disease, one had a large strangulated incisional hernia, one had a sigmoid volvulus, and one had a sigmoid localization of endometriosis. Thirty open left hemicolectomies were performed. In 128 cases, a minimally invasive approach was used. Since conversion to open was necessary in 10 of these cases, 118 were totally LLH. STSA was performed in 64 cases; seven in an emergency setting and 57 in elective procedures. The overall anastomotic leak rate was 3.1% (2/64) and no anastomotic leak was reported in the emergency group (0/7). TA was performed in 15 cases, 93% in an elective setting (14/15), and the anastomotic leak rate was 13.3% (2/15). In 20 cases, we performed elective STEA and no anastomotic leak was recorded. In 19 cases, it was impossible to perform anastomosis and we decided to create a definitive colostomy.
CONCLUSION
Consistent with the literature data, our experience shows that, in selected cases, STSA and STEA are both safe and effective, with a lower anastomotic complication rate than TA.

Meta-Analysis
PURPOSE
The management of intestinal malrotation in infants with omphalocele varies among surgeons. Herein, we aimed to determine whether infants with omphalocele should be investigated for malrotation.
METHODS
Using a defined search strategy, three investigators identified all studies reporting patients with omphalocele and malrotation. Outcome measures included: 1. incidence of malrotation; 2. correlation with the abdominal size defect in patients with omphalocele; 3. risk of volvulus in those not investigated for malrotation; 4. incidence of adhesive bowel obstruction in those who underwent Ladd's procedure. The meta-analysis was conducted according to PRISMA guidelines and using RevMan 5.3.
RESULTS
Of 111 articles analyzed, 12 (3888 children) reported malrotation in 136 patients (3.5%). Malrotation was equally found in patients with major (15.2%) and minor (13.6%; p = 0.52) omphalocele. A volvulus was more common in children who had Ladd's procedure (8%) than in those who did not (1%; p = 0.03). Adhesive bowel obstruction rate was similar in both groups (5% vs. 3%; p = 0.21).
CONCLUSION
The incidence of malrotation in infants with omphalocele is low but probably underreported, and is not influenced by the size of the defect. At present, there is no evidence in the literature to support investigations to detect malrotation in infants with omphalocele.

INTRODUCTION
With improvements in prenatal ultrasound, more abdominal enteric duplication cysts (EDCs) are diagnosed prenatally. The optimal time for operative intervention is unclear. We aimed to review the evidence supporting the indication and timing of surgery for prenatally diagnosed EDCs.
MATERIALS AND METHODS
A systematic review was performed using a defined search strategy identifying articles with inclusion criteria of prenatal diagnosis of histologically confirmed EDCs. Outcomes included (1) indications for resection (symptoms vs. prophylactic) and (2) time from birth to operative intervention.
RESULTS
Of 1,590 articles screened, prenatal diagnosis of histologically confirmed EDCs was made in 68 articles, detailing indications and timing for resection for 86 patients. Thirty-five patients (41%) became symptomatic early and were resected promptly at a median of 2 days of age. Indications for intervention included bowel obstruction, volvulus, bleeding, recurrent pain and diagnostic dilemma (concern for cystic neuroblastoma). There were 51 patients (59%) who were resected prophylactically at a median of 90 days of age without interval symptoms. Symptomatic cysts had a larger mean cyst diameter. There was a difference in the anatomic distribution of asymptomatic or symptomatic EDCs-gastric duplications were more frequently asymptomatic while jejunal, proximal ileal and colonic duplications were more frequently symptomatic.
CONCLUSION
The optimal approach to EDCs diagnosed prenatally is not supported by strong evidence in the literature. Our systematic review indicates that almost half of the infants diagnosed prenatally become symptomatic early and are resected. In asymptomatic patients, close observation and delayed prophylactic resection in infancy can be considered.

AIM
Appendiceal volvulus (AV) and cecal volvulus (CV) are rare conditions and there is no consensus regarding the best surgical approach. This study reviewed CV and AV management and outcomes in children.
METHODS
PubMed was reviewed from 1990 to 2018 for AV and CV in children and studies published in English were selected by two independent reviewers. This identified 24 papers that provided case reports on 29 children (72% male) with a median age of 10 years.
RESULTS
Abdominal distension and abdominal pain were the most common symptoms and seven children had Cornelia de Lange syndrome. The initial treatment was surgical in 27 cases and endoscopic in 2. In 23 children, variants of cecopexy were performed. There was no mortality. Complications occurred in seven cases: five with sepsis and two with enterocutaneous fistulas. There were three CV recurrences and these were all in cases where cecopexy was not performed.
CONCLUSION
AV and CV are rare paediatric pathologies. Since a quarter of the patients had Cornelia de Lange syndrome, it is paramount to consider CV when abdominal symptoms occur. Complications were minor with prompt management. In order to reduce recurrence, cecopexy is recommended in CV cases and appendectomy in AV cases.

Meta-Analysis
BACKGROUND
Intestinal volvulus is a potentially life-threatening condition that occurs when loops of bowel twist around its supporting mesentery and associated vasculature. Clinicians often rely on various radiological investigations for prompt diagnosis to avoid complications such as bowel infarction. This review assesses the clinical reliability of the ultrasonographic whirlpool sign (WS) in the diagnosis of intestinal volvulus.
METHODS
In adherence with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-analyses) statement, a systematic search of BMJ Best Practice, Cochrane Database of Systematic Reviews, EMBASE, Google Scholar, PubMed, Scopus and Web of Science databases was performed (August 2017), using relevant search terms. Selected studies were ranked for quality and relevance using the CASP (Critical Appraisal Skills Program) tool.
RESULTS
Sixteen articles (1640 participants) were assessed. The mean and median sample size was 102.5 (SD ± 192.23) and 28 (range 7-770), respectively. The WS was positive in 212 of 255 (83.1%) patients with intestinal volvulus. Meta-analysis of the studies that provided sufficient data resulted in a pooled sensitivity and specificity of 87.42% (95% confidence interval (CI): 81.05-92.25) and 98.63% (95% CI: 97.88-99.18), respectively, with an estimated summary effect of 5.28 (95% CI: 4.47-6.08, P < 0.001). There was negligible inter-study heterogeneity, which was suggested by an I statistic of 0% (95% CI: 0.00-76.34) and a τ parameter of 0 (95% CI: 0.00-5.35).
CONCLUSION
Though the pooled sensitivity was less than ideal (87.42%), this review and meta-analysis nevertheless supports the reliability of the ultrasonographic WS as an acceptable indicator of intestinal volvulus.

Review
BACKGROUND
Cecal volvulus is a rare clinical entity with an average incidence of 2.8-7.1 per million people per year, accounting for 1-2% of all large bowel obstructions. Cecal bascule is the rarest type of cecal volvulus, accounting for 5-20% of all cases. Although several case reports have been published, there is no consensus regarding its diagnosis and treatment. The aim of this study was to review the literature on cecal bascule in order to summarize the etiopathogenesis, clinical features, diagnosis, and treatment options.
METHODS
The PubMed, MEDLINE, and Scopus databases were systematically searched by two independent authors. Cecal bascule was defined as anterior displacement of the distended cecum on the ascending colon without any torsion. The etiopathogenesis, clinical features, diagnosis, and treatment options were analyzed.
RESULTS
Nineteen previously published papers reporting on 26 patients were included. The mean age of patients from previously reported cases was 55.1 ± 19.2 years, and 54% of all patients were males. Presenting symptoms included abdominal pain in 16 (61%), distension in 22 (84%), and vomiting in eight patients (30%). The mean time to diagnosis was 3.6 ± 2.6 days. The extent of surgery varied from cecopexy to right colectomy. There was no postoperative mortality. Cecal bascule recurred one 1 year after index surgery in one patient.
CONCLUSIONS
Cecal bascule is a rare clinical entity, which is mostly encountered in patients with peritoneal adhesions, mobile cecum, bowel dysfunction, and cecal displacement. In patients with recurrent or persistent abdominal pain and distension, cecal bascule should be considered. The majority of these patients require surgical management.

Meta-Analysis
OBJECTIVE
To determine outcome of children born with isolated gastroschisis (no extra-gastrointestinal congenital abnormalities).
STUDY DESIGN
International cohort study and meta-analysis.
PRIMARY OUTCOME
time to full enteral feeding (TFEF); secondary outcomes: Duration of mechanical ventilation, length of stay (LOS), mortality and differences in outcome between simple and complex gastroschisis (complex; born with bowel atresia, volvulus, perforation or necrosis). To compare the cohort study results with literature three databases were searched. Studies were eligible for inclusion if cases were born in developed countries with isolated gastroschisis after 1990, number of cases >20 and TFEF was reported.
RESULTS
The cohort study included 204 liveborn cases of isolated gastroschisis. The TFEF, median duration of ventilation and LOS was, 26days (range 6-515), 2days (range 0-90) and 33days (range 11-515), respectively. Overall mortality was 10.8%. TFEF and LOS were significantly longer (P<0.0001) and mortality was fourfold higher in the complex group. Seventeen studies, amongst the current study, were included for further meta-analysis comprising a total of 1652 patients. Mean TFEF was 35.3±4.4days, length of ventilation was 5.5±2.0days, LOS was 46.4±5.2days and mortality risk was 0.06 [0.04-0.07 95%CI]. Outcome of simple and complex gastroschisis was described in five studies. TFEF, ventilation time, LOS were significant longer and mortality rate was 3.64 [1.95-6.83 95%CI] times higher in complex cases.
CONCLUSIONS
These results give a good indication of the expected TFEF, ventilation time and LOS and mortality risk in children born with isolated gastroschisis, although ranges remain wide. This study shows the importance of dividing gastroschisis into simple and complex for the prediction of outcome.
