Intestinal obstruction caused by torsed gangrenous Meckel’s diverticulum encircling terminal ileum

Unusual Presentation of Meckel's Diverticulitis Causing Small Bowel Obstruction Masquerading as Appendicitis

Meckel's diverticulum (MD) is a prevalent congenital abnormality of the gastrointestinal tract. While it may not show any symptoms, it has the potential to cause serious complications, such as intestinal obstruction. This case report presents a case of a 27-year-old male who presented to the emergency department with migrating right lower abdomen pain and vomiting. An initial diagnosis of acute appendicitis was made. An erect X-ray of the abdomen showed features of small bowel obstruction and with a clinical suspicion of Meckel's, a diagnostic laparoscopy had been planned. However, the diagnostic laparoscopy identified a gangrenous MD with axial torsion, with an ileal loop knotting at the base of Meckel's, causing small bowel obstruction. This entanglement led to an obstruction, which is a rare and challenging clinical scenario. Surgical resection of the affected bowel segment, including the MD, was performed, leading to a complete recovery of the patient. This case study emphasizes the diagnostic difficulties presented by MD, particularly when its symptoms resemble more prevalent illnesses like appendicitis. The rare incidence of axial torsion resulting in gangrene in MD with small bowel obstruction highlights the significance of including this illness in the differential diagnosis of acute abdomen.

A Rare Case of a Meckel's Diverticulum Complicated by a Mesodiverticular Band

A Meckel's diverticulum is a true congenital diverticulum arising from the ileum, approximately 2 feet from the ileocaecal junction. Named after Johann Meckel, who first described its embryological origins, the anomaly remains asymptomatic for most. Uncommonly, it is found to be the cause of serious complications such as interstitial obstruction and/or gangrene, bowel perforation, and, in rare cases, internal bowel herniations. A mesodiverticular band is a congenital fibrous band connecting the Meckel's diverticulum to its own mesentery, predisposing it to complications. Both conditions arise from a failure of regression of the vitellointestinal duct and its feeding artery. The presence of a mesodiverticular band significantly raises the possibility of complications, especially those of internal herniation and subsequent bowel obstruction. Detection of a Meckel's diverticulum is challenging in routine investigations such as contrast-enhanced computed tomography, and scintigraphy with Tc99 is required. The availability of such scans is limited, and their use is further difficult in emergent situations such as intestinal obstruction. This condition is, therefore, more frequently detected at laparotomies. Herein, we report a case of intestinal obstruction in a young female who presented to our emergency room with an acute abdomen and was found to have a mesodiverticular band causing internal herniation and subsequent obstruction.

Pivotal Surgical Intervention for Pediatric Ileoileal Intussusception With Meckel's Diverticulum: A Case Report

The most prevalent congenital gastrointestinal tract abnormality is Meckel's diverticulum. It is discovered in most instances incidentally. It can be observed as painless bleeding in the gastrointestinal tract. However, it can occasionally result in acute intestinal obstruction, which frequently masks the actual clinical presentation. This is a case of a four-and-a-half-year-old male child who presented with features of obstruction, which, on further evaluation, revealed ileoileal intussusception. An emergency surgical intervention was planned with an exploratory laparotomy and a reduction of intussusception. This case emphasizes the urgency of diagnosing and managing intussusception to prevent serious consequences such as bowel ischemia, bowel necrosis, bowel perforation, peritonitis, and sepsis. It stands as a stark reminder for medical professionals to stay vigilant for these critical gastrointestinal emergencies, and immediate treatment with a multidisciplinary approach is recommended to significantly enhance patient outcomes.

Small Bowel Obstruction Due to Axial Torsion of Meckel's Diverticulum: A Case Report and Literature Review

Meckel's diverticulum (MD) is a commonly encountered congenital gastrointestinal abnormality. Although the frequency of MD-related complications such as inflammation or bleeding is relatively high, small bowel obstruction induced by axial torsion of the MD is rare. Therefore, we herein report such a case along with a review of the literature. A 34-year-old female with right lower quadrant pain, nausea, and vomiting was admitted to our hospital with the diagnosis of adhesive small bowel obstruction due to a cesarean section performed five years previously. A long intestinal tube was placed, and the patient's clinical symptoms and X-ray findings showed relief of the small bowel obstruction. However, she developed severe right lower quadrant pain after contrast examination through the long intestinal tube despite the fact that the contrast agent had smoothly reached the terminal ileum. Blood tests and enhanced computed tomography (CT) showed a remarkable elevation of inflammatory markers, the appearance of ascites, and closed-loop-like and abscess-like appearances near the site of the caliber change. With a diagnosis of internal hernia, the patient underwent emergency laparotomy by means of a midline incision. Purulent ascites was observed within the abdominal cavity. Small bowel obstruction caused by a single band was observed in the right lower quadrant. Further exploration revealed an inflammatory MD with neck torsion and a mesodiverticular band (MDB). Simple mesodiverticular band resection by electrocautery and diverticulectomy by linear stapler were performed. The postoperative course was uneventful, and the patient was discharged on postoperative day 7. In the case of juvenile-onset small bowel obstruction, axial torsion of the MD should be considered as a differential diagnosis. Herein, we report such a difficult diagnostic case and the first English literature review of small bowel obstruction due to axial torsion of the MD.

Meckel's diverticulum causing acute intestinal obstruction: A case series

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. Most cases are asymptomatic and when symptomatic, preoperative diagnosis of MD is poor. Intestinal obstruction, Malena or hematochezia, and inflammation are major symptoms. We report three cases of 18-month, 2-year, and 9-year old male patients presenting with intestinal obstruction.

Meckel's diverticulum causing acute intestinal obstruction: A case report and comprehensive review of the literature

Introduction

Meckel's diverticulum is a congenital anomaly that is often detected incidentally. When it presents symptomatically, it causes painless gastrointestinal bleeding. Nevertheless, in rare instances, it can cause acute intestinal obstruction, often obscuring the true clinical picture.

Case presentation

A 31-year-old male presented to the emergency department with a 24-h history of unremitting nausea, biliary emesis, abdominal distension, and absolute constipation. After ruling out the most common etiologies of acute bowel obstruction, radiological imaging was obtained and was suggestive of meckel's diverticulum. Laparoscopic meckel's diverticulectomy was performed, with the subsequent histopathological analysis confirming ectopic gastric tissue.

Discussion

Meckel's diverticulum occurs consequent to incomplete obliteration of the vitelline or omphalomesenteric duct, which connects the developing intestines to the yolk sac. It is found in roughly 2% of the population, of which only about 4% may become symptomatic due to any number of complications. Specifically, small bowel obstruction (SBO) and diverticulitis secondary to ectopic gastric or pancreatic tissue are the most common presentations of symptomatic MD.

Conclusion

Although relatively rare in adults, MD should be considered in the list of differentials in patients with intussusception leading to SBO, especially on a background history unremarkable for the most common etiologies causing SBO including post-operative adhesions and hernias.

Torsed gangrenous Meckel's diverticulum causing gangrenous ileal segment: A rare case report of small bowel obstruction in children

INTRODUCTION

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal system. It is caused by an incomplete obliteration of the vitelline duct. Rarely, it can present with complications like torsion and gangrene formation.

CASE PRESENTATION

A 13-year previously healthy girl presented with sudden onset periumbilical pain and bilious vomiting who was subsequently diagnosed with Meckel's diverticulum. Intraoperatively, torsed gangrenous diverticulum forming band adhesion was found. Resection of Meckel's diverticulum along with gangrenous ileal segment followed by ileoileal anastomosis was done.

DISCUSSION

Axial torsion of Meckel's diverticulum with gangrene formation is a rare occurrence. Mesodiverticular band adhesion along with herniation of small bowel segments under it endangers viability of herniating segments. Preoperative diagnosis of complicated MD is difficult as it mimics other common acute abdominal conditions. CT scan and enteroclysis are imaging modalities of choice. Surgical resection of MD along with resection and anastomosis of gangrenous bowel segment results in complete cure.

CONCLUSION

Meckel's diverticulum with complications should be kept in the differential of acute abdominal conditions presenting with atypical symptoms. Surgical resection ensures complete cure.

Persistence of a vitelline artery on a Meckel's diverticulum as a cause of bowel infarction

Meckel's diverticulum is a congenital anomaly, resulting from incomplete obliteration of the most proximal portion of the omphalomesenteric duct. It generally remains silent, but life-threatening complications may arise in 4-6% of the patients. We present a case of a 16-year-old male, who arrived at the emergency room with crampy abdominal pain, nausea, and vomiting, suggestive of acute appendicitis. Surgical exploration revealed 150 cm of infarcted small bowel, secondary to a mesodiverticular band of a Meckel's diverticulum at the site of obstruction. The ischemic small bowel with Meckel's diverticulum was resected, and an ileo-ileal anastomosis was carried out. The postoperative course was uneventful, and the patient was discharged on the fifth postoperative day. He was seen 12 months after his initial surgery, with a favorable outcome.

Unusual cause of small bowel obstruction: mesodiverticular band of Meckel's diverticulum demonstrated by CT

Small bowel obstruction resulting from the mesodiverticular band is a rare complication of Meckel’s diverticulum and usually presents a diagnostic challenge. We present a case of small bowel obstruction due to the mesodiverticular band of Meckel’s diverticulum with CT scan findings.

An unusual case of intraabdominal abscess and acute abdomen caused by axial torsion of a Meckel's diverticulum

BACKGROUND

Meckel's diverticulum (MD), the most common congenital anomaly of the gastrointestinal tract, is a true diverticulum. MD is mostly seen in pediatric age groups but may be seen in adults as well. Is twice common in men than women. Surgical treatment is required in symptomatic MD patients. We present a 21-year-old female patient who was admitted with acute abdomen and underwent diverticulectomy with diagnosis of Meckel's diverticulum.

PRESENTATION OF CASE

The 21-year-old female patient was admitted to emergency service with abdominal pain, nausea and vomiting. Physical examination revealed abdominal distention, rebound tenderness and defense. Abdominal radiography revealed air-fluid levels. White blood cell count was high. In the exploration, torsion of MD was observed and diverticulectomy was performed. Histopathologic analysis indicated the presence of MD. The patient recovered without complication, and was uneventfully discharged.

DISCUSSION

MD is found in 2% of the general population. Common complications of MD include gastrointestinal bleeding, intestinal obstruction, perforation and diverticulitis. However, axial torsion of MD is a rare complication. Simple diverticulectomy is sufficient in the treatment of most MD cases; however, ileal resection may be required in some cases. Diagnosis of MD is established by histopathologic analysis.

CONCLUSION

Although MD is known as a pediatric disease, it is likely to occur in adults as well. Axial torsion of Meckel's diverticulum should be kept in mind the adults presenting with symptoms of acute abdomen.

Unusual presentation of a Meckel's diverticulum: A case report

•

Meckel’s diverticulum is the most common congenital malformation of the gut.

•

Several risk factors for developing symptomatic MD have been identified.

•

Intestinal obstruction is the most common presenting symptom in adults.

•

Pre-operative diagnosis remains elusive even with the appropriate imaging techniques.

Introduction

Meckel’s diverticulum (MD) is the most common congenital malformation of the gastrointestinal tract. Intestinal obstruction is the lead presenting symptom in the adult population due to multiple causes (intussusception, incarceration, adhesions, strictures and torsion). Our patient had a complicated MD with an unique combination of risk factors and findings.

Presentation of case

We report an unusual case of an 18-year-old patient presenting with acute small bowel obstruction for several days, who developed focal peritoneal signs on right lower quadrant. On laparotomy, findings included a necrotic giant MD and a small bowel volvulus around a fibrous band that attached MD to the umbilicus. Segmental enterectomy with primary anastomosis was performed.

Discussion

Axial torsion and gangrene of MD is the rarest complication. Its pre-operative diagnosis remains elusive as it can be clinically indistinguishable from other intra-abdominal inflammatory conditions. The correct diagnosis of complicated MD before surgery is often difficult because this condition can mimic other acute abdominal pathologies. There are several risk factors that can point to an accurate and early diagnosis, especially when combined with the appropriate imaging techniques, such as computed tomography with oral and intravenous contrast.

Conclusion

This complication remains underdiagnosed, often with delayed surgical intervention and sub-optimal treatment that leads to significant morbidity and mortality.

Torsion of Meckel's diverticulum as a cause of small bowel obstruction: A case report

Axial torsion and necrosis of Meckel’s diverticulum causing simultaneous mechanical small bowel obstruction are the rarest complications of this congenital anomaly. This kind of pathology has been reported only eleven times. Our case report presents this very unusual case of Meckel’s diverticulum. A 41-year-old man presented at the emergency department with complaints of crampy abdominal pain, nausea and retention of stool and gases. Clinical diagnosis was small bowel obstruction. Because the origin of obstruction was unknown, computer tomography was indicated. Computed tomography (CT)-scan revealed dilated small bowel loops with multiple air-fluid levels; the oral contrast medium had reached the jejunum and proximal parts of the ileum but not the distal small bowel loops or the large bowel; in the right mid-abdomen there was a 11 cm × 6.4 cm × 7.8 cm fluid containing cavity with thickened wall, which was considered a dilated bowel-loop or cyst or diverticulum. Initially the patient was treated conservatively. Because of persistent abdominal pain emergency laparotomy was indicated. Abdominal exploration revealed distended small bowel loops proximal to the obstruction, and a large (12 cm × 14 cm) Meckel’s diverticulum at the site of obstruction. Meckel’s diverticulum was axially rotated by 720°, which caused small bowel obstruction and diverticular necrosis. About 20 cm of the small bowel with Meckel’s diverticulum was resected. The postoperative course was uneventful and the patient was discharged on the fifth postoperative day. We recommend CT-scan as the most useful diagnostic tool in bowel obstruction of unknown origin. In cases of Meckel’s diverticulum causing small bowel obstruction, prompt surgical treatment is indicated; delay in diagnosis and in adequate treatment may lead to bowel necrosis and peritonitis.

Axial Torsion of Gangrenous Meckel's Diverticulum Causing Small Bowel Obstruction

Meckel's diverticulum (MD) is a commonly encountered congenital anomaly of the small intestine. We report an extremely unusual case of an axially torted, gangrenous MD presenting as acute intestinal obstruction. A 26-year-old male patient presented to our emergency department with 3 days history of abdominal pain, distention and bilious vomiting. On laparotomy, there was minimal hemorrhagic fluid localized in right iliac fossa and small bowel loops were dilated. A MD was seen attached to the mesentery of nonadjacent small bowel by a peritoneal band. The diverticulum was axially torted and gangrenous. In addition, there was compression of ileum by the peritoneal band resulting in intestinal obstruction, which was relieved on dividing the band. Resection and anastomosis of the small bowel including the MD was performed. We hereby report a rare and unusual complication of a MD. Although treatment outcome is generally good, pre-operative diagnosis is often difficult.

Giant Meckel’s diverticulum: An exceptional cause of intestinal obstruction

Meckel’s diverticulum (MD) results from incomplete involution of the proximal portion of the vitelline (also known as the omphalomesenteric) duct during weeks 5-7 of foetal development. Although MD is the most commonly diagnosed congenital gastrointestinal anomaly, it is estimated to affect only 2% of the population worldwide. Most cases are asymptomatic, and diagnosis is often made following investigation of unexplained gastrointestinal bleeding, perforation, inflammation or obstruction that prompt clinic presentation. While MD range in size from 1-10 cm, cases of giant MD (≥ 5 cm) are relatively rare and associated with more severe forms of the complications, especially for obstruction. Herein, we report a case of giant MD with secondary small bowel obstruction in an adult male that was successfully managed by surgical resection and anastomosis created with endoscopic stapler device (80 mm, endo-GIA stapler). Patient was discharged on post-operative day 6 without any complications. Histopathologic examination indicated Meckel’s diverticulitis without gastric or pancreatic metaplasia.
