RESUMO
BACKGROUND: The aims of this study were to summarize the clinical presentation and histological results of 20 cases of complicated Meckel diverticulum (MD) who were presumed to have acute appendicitis before surgery, as well as to improve the diagnosis and treatment of complicated MD in children. MATERIALS AND METHODS: We retrospectively reviewed the records of 20 complicated MD admitted to our institution who were preoperatively diagnosed with acute appendicitis from January 2012 to January 2019. Patients were divided into the perforated MD group and the Meckel's diverticulitis group. Patient demographics, clinical manifestations, laboratory data, auxiliary examinations, surgical methods, and the result of heterotopic tissue were recorded. RESULTS: A total of 20 cases of complicated MD (perforated or diverticulitis) were identified. Children were aged from 3 to 13 years, with a mean age of 7.75 years (median 7.75; range, 1-13 years). Perforated Meckel's diverticulum occurred in 5 of 20 (25%) cases. For perforated MD versus diverticulitis, no significant differences were found between age, time to intervention, length of hospital stay, and distance from the ileo-cecal valve. Heterotopic tissue was confirmed on histopathology in 75% of all patients, including 10 cases of gastric mucosa, 3 cases of coexistent gastric mucosa and pancreatic tissue, and 2 cases of pancreatic tissue. All patients underwent diverticulectomy or partial ileal resection under laparoscopy or laparotomy; two cases combined with appendectomy owing to slight inflammation of the appendix. CONCLUSIONS: The most common presentation of symptomatic MD is painless rectal bleeding; however, it can present symptoms of acute abdomen mimicking acute appendicitis. The key point of diverticulectomy is to remove the ectopic mucosa completely.

OBJECTIVE: Heterotopic pancreas, an uncommon condition in children, can present with diagnostic and treatment challenges. This study aimed to evaluate the clinical features and treatment options for this disorder in pediatric patients. METHODS: We conducted a retrospective analysis, including patients diagnosed with heterotopic pancreas at four tertiary hospitals between January 2000 and June 2022. Patients were categorized into symptomatic and asymptomatic groups based on clinical presentation. Clinical parameters, including age at surgery, lesion size and site, surgical or endoscopic approach, pathological findings, and outcome, were statistically analyzed. RESULTS: The study included 88 patients with heterotopic pancreas. Among them, 22 were symptomatic, and 41 were aged one year or younger. The heterotopic pancreas was commonly located in Meckel's diverticulum (46.59%), jejunum (20.45%), umbilicus (10.23%),ileum (7.95%), and stomach (6.82%). Sixty-six patients had concomitant diseases. Thirty-three patients had heterotopic pancreas located in the Meckel's diverticulum, with 80.49% of cases accompanied by gastric mucosa heterotopia (GMH). Patients without accompanying GMH had a higher prevalence of heterotopic pancreas-related symptoms (75%). Treatment modalities included removal of the lesions by open surgery, laparoscopic or laparoscopic assisted surgery, or endoscopic surgery based on patient's age, the lesion site and size, and coexisting diseases. CONCLUSIONS: Only one-fourth of the patients with heterotopic pancreas presented with symptoms. Those located in the Meckel's diverticulum have commonly accompanying GMH. Open surgical, laparoscopic surgical or endoscopic resection of the heterotopic pancreas is recommended due to potential complications. Future prospective multicenter studies are warranted to establish rational treatment options.

Intussusception is rare in adults, accounting for 1 to 5 % of mechanical bowel obstructions. It is due to pathologic lead point within the bowel which is malignant in up to 77 % of cases. Benign lesions may also be responsible for intussusception (polyp, Meckel diverticulum). The lead point is pulled forward by normal peristaltism, prolapsing the affected segment of bowel into another segment. The most common presentation in adults is intermittent abdominal pain and bowel obstruction (nausea, vomiting, inability to pass gas or stools). Abdominal scanner is the key exam for the diagnosis and the treatment is always surgical resection.
Les invaginations grêles et coliques sont rares chez l'adulte, représentant 1 à 5 % des causes d'obstruction digestive mécanique. Elles sont le plus souvent causées par une masse intra-digestive, le péristaltisme entraînant un prolapsus du segment malade vers un segment intestinal adjacent. Elles sont généralement le reflet d'une pathologie maligne du tube digestif (tumeur maligne découverte dans plus de 77 % des cas), mais il peut également exister des causes béniqnes (polype, diverticule de Meckel, adénopathie) . Elles se manifestent sous forme de douleurs abdominales et d'occlusion (nausées, vomissements, arrêt des selles et des gaz). Le scanner abdominal est l'examen de choix pour poser le diagnostic. Le traitement est toujours une résection chirurgicale.

BACKGROUND AND AIMS: Meckel's diverticulum (MD) may remain silent or be associated with adverse events such as GI bleeding. The main aim of this study was to evaluate indicative small-bowel capsule endoscopy (SBCE) findings, and the secondary aim was to describe clinical presentation in patients with MD. METHODS: This retrospective European multicenter study included patients with MD undergoing SBCE from 2001 until July 2021. RESULTS: Sixty-nine patients with a confirmed MD were included. Median age was 32 years with a male-to-female ratio of approximately 3:1. GI bleeding or iron-deficiency anemia was present in nearly all patients. Mean hemoglobin was 7.63 ± 1.8 g/dL with a transfusion requirement of 52.2%. Typical capsule endoscopy (CE) findings were double lumen (n = 49 [71%]), visible entrance into the MD (n = 49 [71%]), mucosal webs (n = 30 [43.5%]), and bulges (n = 19 [27.5%]). Two or more of these findings were seen in 48 patients (69.6%). Ulcers were detected in 52.2% of patients (n = 36). In 63.8% of patients (n = 44), a combination of double lumen and visible entrance into the MD was evident, additionally revealing ulcers in 39.1% (n = 27). Mean percent SB (small bowel) transit time for the first indicative image of MD was 57% of the total SB transit time. CONCLUSIONS: Diagnosis of MD is rare and sometimes challenging, and a preoperative criterion standard does not exist. In SBCE, the most frequent findings were double-lumen sign and visible diverticular entrance, sometimes together with ulcers.

BACKGROUND: To analyze the diversity in endoscopic manifestations of Meckel's diverticulum (MD) in adults by using balloon-assisted enteroscopy (BAE) and supply more information on the application of BAE. METHODS: A retrospective study was carried out on adult patients diagnosed with MD by BAE in two tertiary general hospitals in China, from May 2007 to September 2021. The patients were divided into a small bowel bleeding (SBB) group and a control group according to their main symptoms. Clinical charts and endoscopic images were reviewed, analyzed, and summarized. RESULTS: Single diverticulum in the ileum and double-lumen sign were observed in all patients. The SBB group consisted of 51 patients, among which 35 cases of ulcerative lesions, 9 cases of erosive lesions, 9 cases of active bleeding/blood clots, and 4 cases of lumps inside the diverticulum were observed respectively. Majority of ulcerative lesions were inside the diverticulum (23/35). A circumferential stricture inside the diverticulum was discovered in 11 cases, and ulcerative lesions tended to occur at this structure (10/11). In the control group consisting of 15 patients, 1 case of erosive lesions at the orifice edge was observed. The percentage of patients with MD-associated ulcerative lesions was significantly higher in the SBB group than that in the control group (p < 0.001). CONCLUSIONS: The endoscopic manifestations of MD in adults are extraordinarily complex and connected with the patients' primary symptoms. The internal features of MD should be regarded as crucial observational objectives in adult patients.

Meckel diverticulum, the most common congenital anomaly of the gastrointestinal tract, results from the aberrant involution of the omphalomesenteric duct and accounts for more than 50% of unexplained lower gastrointestinal bleeding in the pediatric population. The most accurate imaging tool to identify a Meckel diverticulum containing ectopic gastric mucosa is the Technetium-99m pertechnetate Meckel scan, a scintigraphic study with a reported accuracy of 90% in the pediatric population. In addition to depicting a Meckel diverticulum with ectopic gastric mucosa, careful attention to the normal biodistribution of the radiotracer can lead to the identification of unexpected pathology with implications for patient management. This article serves to review the embryological origin and anatomical features of Meckel diverticulum, highlight the role of scintigraphy in evaluating Meckel diverticulum, and discuss the proper imaging technique when performing this test. We will focus on pitfalls that can lead to an erroneous diagnosis as well as incidental findings that can affect patient management.

OBJECTIVE: To explore clinical characteristics, pathogenesis, diagnosis and treatment of intestinal obstruction due to mesodiverticular band (MDB) in children in a single center in China. METHODS: The clinical data of 20 children with acute intestinal obstruction due to MDB between 1998 and 2020 were retrospectively analyzed. RESULTS: The male-to-female ratio was 14:6 in 20 cases. Except one case of 7-month pregnant stillbirth, the cases were aged from 7 days to 14 years, at the median age of 4.31 years. The common symptoms were vomiting, abdominal pain and/or abdominal distension. About 40% (8/20) of patients had both MDB and Meckel's Diverticulum (MD), while 60% (12/20) of patients had MDB only. Only one case died because of total colonic aganglionosis, while other children recovered after surgery treatment. MDB led to the strangulation of necrotic bowel in six cases, intestinal perforation in one case, and intestinal rupture in one case. Pathologic examination showed thick-walled arteries and or thick venous vascular structures in the cord. All cases had no complications during 1-year follow-up. CONCLUSION: MDB results from the remnant of vitelline vessel, and often causes acute intestinal obstruction without special clinical symptoms. Unexplained abdominal pain and distension without surgery history should be paid attention, especially for strangulated intestinal obstruction. Timely surgical exploration is beneficial to avoid intestinal necrosis or even sudden death, and the pathological examination is important for the diagnosis.

BACKGROUND: Meckel's diverticula result from incomplete obliteration and regression of the omphaloenteric duct and are the most common congenital intestinal malformations. Many Meckel's diverticula remain asymptomatic and are discovered as incidental findings. They present a diagnostic challenge. METHODS: We report the case of a 35-year-old man who presented with an acute abdomen and ileus. Computed tomography of the abdomen showed a mechanical small bowel ileus. There was a calibre jump in the terminal ileum with a round endoluminal definable hyperdense structure of almost 2 cm in diameter. RESULTS: An exploratory laparoscopy was performed revealing an inflamed Meckel's diverticulum with impacted enterolith as the cause of the intestinal obstruction. CONCLUSION: In symptomatic Meckel's diverticula, haemorrhage and obstruction are the most common complications. The development of ileus due to a Meckel's diverticulum with an enterolith is considered extremely rare but should be taken into account.

Background: A button battery can cause perforation of Meckel's diverticulum if sequestered in this blind ending bowel segment. Reported cases focused on clinical manifestations, management options, radiologic and intraoperative findings. We highlight the histopathologic features in perforated Meckel's diverticula due to ingested button batteries. Case report: Three toddlers presented with perforated Meckel's diverticula after button battery ingestion. Histologic examination of the diverticula showed multiple burn-like mucosal ulcerations and liquefactive wall perforations of the tips, associated with prominent siderotic pigment deposits and calcifications. There were various residual materials with variable staining patterns in the luminal debris, necrotic tissue and adjacent to submucosal blood vessels. Conclusion: There is accelerated deposition of iron and calcium associated with button batteries.

BACKGROUND: Despite numerous reports on ischemic bowel obstruction caused by internal hernia, no case presentation has been reported of an internal hernia caused by a bridge formed between the medial and lateral zones of the liver. Herein, we report the first case of ischemic bowel obstruction caused by a hepatic bridge. CASE PRESENTATION: A 24-year-old man complaining of abdominal pain was referred to our hospital and admitted. Computed tomography showed formation of a closed loop of small bowel with a hernia orifice near the hilar region, and poor contrast of the prolapsed small bowel. We suspected ischemic bowel obstruction caused by an internal hernia with a fissure of the greater omentum as the hernia orifice, and performed emergency surgery. Laparoscopic observation revealed that the medial and lateral segments of the liver formed a bridge on the dorsal side at the liver portal, and that the small intestine was ischemic in the gap created between the bridge and the medial and lateral liver segments. A Meckel's diverticulum was also invaginated in the gap. The bridge was dissected out and the hernia orifice was opened to release the bowel obstruction. The small bowel was preserved and the Meckel's diverticulum was resected. The patient's postoperative course was uneventful. CONCLUSIONS: We experienced a case of ischemic bowel obstruction caused by hepatic bridge formation, which was successfully treated by laparoscopic surgery.

A 25-year-old woman visited our department due to intermittent defecation of black stool and periumbilical pain for 2 years. Abdominal physical examination showed no obvious abnormality. Laboratory examination showed positive fecal occult blood. Because bleeding lesions were not found by gastroscopy or colonoscopy, she underwent double-balloon enteroscopy examination. It was found that a diverticulum was formed in the terminal ileum, with blood exudation. After repeated washing, the blood disappeared. However, after a period of time, blood exudation could still be detected there. She was diagnosed as Meckel's diverticulum with hemorrhage. Considering the patient's repeated gastrointestinal bleeding, surgical treatment was performed. Surgical specimens showed a 2.5×2.3×1.5 cm3 intestinal diverticulum with a soft texture, and the mucosa was grayish white. Postoperative pathological showed ectopic gastric mucosa with chronic inflammatory cell infiltration. The diverticulum had been found to contain gastric fundus gland tissues which were mainly composed of parietal cells and main cells. The patient recovered well after operation.

BACKGROUND: Meckel's diverticulum (MD) is a remnant of the omphalomesenteric duct. Although the majority of MD are asymptomatic, it can present with severe hematochezia. Hematochezia is generally considered to result from a peptic ulcer caused by ectopic gastric mucosa in MD. However, this hypothesis has not been proved. METHODS: 10 cases of surgically resected MD initially presenting with severe hematochezia were histologically examined. RESULTS: Ectopic gastric mucosa was present in 9 cases, two of which also contained ectopic pancreas. No ectopic tissue was found in one case, which shows that bleeding can occur in MD without ectopic gastric mucosa. In addition, a rupture of aberrant submucosal arterioles through the overlying mucosa, a vascular abnormality called Dieulafoy's lesion, was detected in all the 10 cases. CONCLUSION: This study suggests that the actual cause of massive bleeding in MD is not a peptic ulcer, but Dieulafoy's lesion.

Meckel's diverticulum (MD)1, the most common congenital anomaly of the gastrointestinal tract, occurs in 2% of the population with males being more symptomatic than females. In this case, a 32-year-old male presented with sudden onset colicky abdominal pain, bilious vomiting, and absolute constipation. Emergency laparotomy was done on his virgin abdomen, as a result MD and vitelline cyst along with a fibrous cord connecting the two were identified. Knotting of an ileal loop around this cord had resulted in intestinal obstruction. Meckel's diverticulectomy, along with cord resection, was carried out. The patient made smooth recovery and was discharged on the fifth postoperative day with no complications. The importance of this study is to highlight the case of symptomatic MD in an adult male as it can be a cause of intestinal obstruction and should always be considered in a patient presenting with symptoms of intestinal obstruction.

Meckel's diverticulum is the most common gastrointestinal tract's congenital abnormality. Spontaneous perforation of Meckel's diverticulum is very rare and can mimic acute appendicitis. Here we report the case of an 11-year-old male patient, who was presented to the Surgical A unit of Ayub Teaching Hospital, Abbottabad on 21st January, 2021 with one-day history of abdominal pain, predominantly in the periumbilical area and right iliac fossa, associated with nausea. On physical examination his abdomen was tense, tender with guarding and generalized rigidity. A provisional diagnosis of perforated appendix or enteric perforation of a hollow viscus was made. The patient had an emergency laparotomy, where a perforated Meckel's diverticulum was discovered. Resection of the portion of gut containing Meckel's diverticulum was done along with primary anastomosis. Heterotopic gastric mucosa of diverticulitis, associated with perforation was confirmed on histopathology. The patient made an uneventful recovery during postoperative period. This case report is an interesting and an unusual case of Meckel's diverticulum complication. It highlights the importance of considering Meckel's diverticulum as a differential diagnosis in every patient presenting with acute abdomen in this age group.

Congenital anomalies of the tubular gastrointestinal tract are an important cause of morbidity not only in infants, but also in children and adults.The gastrointestinal (GI) tract, composed of all three primitive germ layers, develops early during embryogenesis. Two major steps in its development are the formation of the gut tube (giving rise to the foregut, the midgut and the hindgut), and the formation of individual organs with specialized cell types.Formation of an intact and functioning GI tract is under strict control from various molecular pathways. Disruption of any of these crucial mechanisms involved in the cell-fate decision along the dorsoventral, anteroposterior, left-right and radial axes, can lead to numerous congenital anomalies, most of which occur and present in infancy. However, they may run undetected during childhood.Therapy is surgical, which in some cases must be performed urgently, and prognosis depends on early diagnosis and suitable treatment.A precise pathologic macroscopic or microscopic diagnosis is important, not only for the immediate treatment and management of affected individuals, but also for future counselling of the affected individual and their family. This is even more true in cases of multiple anomalies or syndromic patterns.We discuss some of the more frequent or clinically important congenital anomalies of the tubular GI, including atresia's, duplications, intestinal malrotation, Meckel's diverticulum and Hirschsprung's Disease.

Meckel's diverticulum is the most common congenital defect of the gastrointestinal tract. It is most often silent or asymptomatic. However, acute abdominal signs of obstruction, inflammation, hemorrhage and perforation are possible in other cases. Different foreign bodies can cause perforation of Meckel's diverticulum. We present an 18-year-old male who presented to the emergency department with abdominal pain within 48 previous hours. After evaluation, acute appendicitis was diagnosed and he underwent laparoscopic appendectomy. Meckel's diverticulum perforated by a fish bone was intraoperatively discovered. Incidental appendectomy and segmental resection of the ileum were performed.

BACKGROUND: Meckel's Diverticulum (MD) is a common congenital anomaly accounting for half of pediatric gastrointestinal bleeds. No large-scale studies exist comparing open and laparoscopic surgery and conversion rates remain high. We sought to compare postoperative outcomes associated with each approach and to determine risk factors for conversion. MATERIALS AND METHODS: NSQIP-Pediatric was used to identify patients who underwent a MD resection from 2012 to 2018. Outcomes between patients treated with a laparoscopic versus open versus laparoscopic converted to open (LCO) surgery were compared. Chi-square tests and adjusted logistic regression analysis were used to determine significance and factors associated with conversion. RESULTS: Six hundred eighty-one patients were identified, 295 (43.3%) underwent open, 267 (39.2%) laparoscopic, and 119 (17.5%) LCO resection. Patients undergoing laparoscopic compared to open procedures had shorter length of stay (LOS; 3 versus 4, P= 0.009), and similar morbidities (10.5% versus 16.6%, P= 0.164) and operative times (71.6 versus 76.6 mins, P= 0.449) on adjusted analysis. Patients with LCO compared to open procedures had similar LOS (4 versus 4, P= 0.334) and morbidities (14.3% versus 16.6%, P= 0.358), but longer operative times (90.1 versus 76.6 mins, P= 0.002) on adjusted analysis. Patients with laparoscopic and LCO procedures had fewer unplanned intubations compared to open procedures (0.0% versus 0.0% versus 2.4%, P= 0.011) and lower mortality (0.0% versus 0.0% versus 1.7%, P= 0.046) on univariate analysis. CONCLUSIONS: Laparoscopic MD resection has shorter LOS and similar complications and operative time compared to an open approach while LCO resection increases operative time but not LOS or morbidities.

The omphalomesenteric duct is an embryologic structure that connects the yolk sac with the primitive midgut of the developing fetus. Omphalomesenteric duct anomalies include a group of entities that result from failed resorption of the omphalomesenteric duct. These anomalies include Meckel diverticulum, omphalomesenteric fistula, fibrous bands, cysts, and umbilical polyps. Meckel diverticulum is the most common congenital anomaly of the gastrointestinal tract and is usually asymptomatic. Symptoms develop when Meckel diverticulum involves complications such as hemorrhage, inflammation, and perforation, or when it causes intussusception or bowel obstruction. Hemorrhage is the most common complication of Meckel diverticulum, and technetium 99m-pertechnetate scintigraphy is the imaging modality of choice for detecting acute bleeding. US and CT are commonly used for the evaluation of patients with other complications such as obstruction and inflammation. Nevertheless, the diagnosis of these complications can be challenging, as their clinical manifestations are usually nonspecific and can masquerade as other acute intraabdominal entities such as appendicitis, inflammatory bowel disease, or other causes of bowel obstruction. There are other umbilical disorders, such as urachal remnants and umbilical granuloma, that may present with symptoms and imaging findings similar to those of omphalomesenteric duct anomalies. An accurate preoperative diagnosis of omphalomesenteric duct anomaly is crucial for appropriate management and a better outcome, particularly when these anomalies manifest as a life-threatening condition. The authors review the anatomy, clinical features, and complications of omphalomesenteric duct anomalies in children, describing the relevant differential diagnoses and associated imaging findings seen with different imaging modalities. ©RSNA, 2021.

ABSTRACT: Children with abdominal pain are frequently seen in emergency departments. Physicians and parents worry about appendicitis; physicians are also concerned about intussusception and bowel obstruction in patients with previous surgical procedures. Sometimes the patient is ill, and the diagnosis is elusive. In a 6-month period at our pediatric emergency department with an annual census of 57,400 patients, we cared for 4 patients who presented with abdominal pain due to complications of Meckel's diverticulum. None presented with painless rectal bleeding, the complication of which physicians are most aware. We are reporting these patients to raise awareness of Meckel's diverticulum as a cause of acute abdomen in children. Meckel's diverticulum may masquerade as appendicitis, an abdominal mass, intussusception, or a complication of severe constipation.
