The superior mesenteric artery (SMA) is vital for parts of the small intestine and ascending colon. Thrombosis of this major artery is a severe and potentially fatal condition involving the occlusion of the arterial vascular supply, causing ischemia predisposing to gangrene. Meckel's diverticulum is a congenital outpouching in the lower part of the small intestine. The condition of gangrenous meckels diverticulum is, therefore, even more limited. This study presents a unique case of a 45-year-old male with coexisting features of SMA thrombus with acute small bowel intestinal obstruction. During the study, the patient was found to have sickle cell anemia with an AS pattern, which may have predisposed the formation of a thrombus. The patient underwent sequential management of active thrombus by thrombolysis first, followed by resection anastomosis for gangrenous bowel. With precise monitoring and therapeutic care, the patient made a remarkable recovery. The condition possesses a high mortality rate. Prompt recognition and timely intervention in this case are of utmost significance.

BACKGROUND
Malignant neoplasms arising from Meckel's diverticulum are rare and an adenocarcinoma in Meckel's diverticulum originating from ectopic pancreatic tissue is even rarer. Herein, we report a patient with an ectopic pancreatic adenocarcinoma in Meckel's diverticulum who was successfully treated with surgery and chemotherapy.
CASE PRESENTATION
A woman in her sixties presented to another hospital with abdominal pain. Plain computed tomography suggested an abdominal tumor and she was referred to our hospital. Enhanced computed tomography revealed a 23-mm low-density tumor in the abdominal cavity. Surgery was performed with a tentative diagnosis of a mesenteric tumor, such as a gastrointestinal stromal tumor, schwannoma, or lymphoma. First, we inspected the peritoneal cavity with a laparoscope. This revealed numerous nodules in the small bowel mesentery, suggesting peritoneal dissemination. A 20-mm-diameter white tumor was found in the small intestine and diagnosed as a small intestinal cancer. The small intestine was partially resected laparoscopically through a small skin incision. The patient's postoperative course was uneventful, and she was discharged on postoperative day 9. Pathological examination revealed well-differentiated adenocarcinoma in the small intestine. The tumor had developed from a sac-like portion protruding toward the serosal side and had a glandular structure lined with flattened atypical cells. Neither pancreatic acinar cells nor islets of Langerhans were evident, suggesting a Heinrich type 3 ectopic pancreas. The final diagnosis was an adenocarcinoma originating from an ectopic pancreas in Meckel's diverticulum. After a smooth recovery, the patient commenced chemotherapy for pancreatic cancer.
CONCLUSIONS
We present a very rare case of ectopic pancreatic carcinoma in Meckel's diverticulum.

Vesicoenteric fistulas are rare, with an incidence of 0.1%-0.2% in the general population, and Meckel's diverticulum is a rare cause, accounting for less than 5% of cases with challenging diagnosis due to atypical symptoms at the admission. This article presents a case of a vesicoenteric fistula formation between Meckel's diverticulum perforated by a foreign body and urinary bladder in a 38-years-old Caucasian male admitted to emergency department due to colicky abdominal pain located in the lower abdomen. An extensive review of the literature was conducted referring all the cases of vesicoenteric fistula incorporating Meckel's diverticulum to elucidate the clinical characteristics, explore the diagnostic yield, and to summarize the therapeutic approach.

INTRODUCTION
Appendiculocolonic fistulas, often arising from benign conditions like abscess-forming appendicitis, manifest subtly. This case emphasizes their rarity, intraoperative discovery during acute appendicitis, and explores diagnostic intricacies, sensitive imaging, and distinctions in managing benign versus malignant cases.
CASE PRESENTATION
A 23-year-old intellectually disabled patient, lacking regular medical follow-up and surgical history, presented to our emergency department with persistent right iliac fossa pain six months ago. Due to financial constraints, a CT scan was not performed despite an inflammatory syndrome, and the patient left against medical advice. Currently experiencing the same symptoms, investigations led to the diagnosis of acute appendicitis with a probable appendico-sigmoid fistula. Surgical exploration confirmed the appendico-sigmoid fistula and the presence of an uncomplicated Meckel's diverticulum. A conservative approach, including appendectomy, Meckel's diverticulum resection, and sigmoid fistula suturing, yielded favorable results.
CLINICAL DISCUSSION
Appendiculocolonic fistulas often arise from acute or chronic appendicitis with local abscess formation. Our case highlights the unusual progression of untreated acute appendicitis, evolving into an appendico-sigmoid fistula. While generally benign, documented cases of malignant causes, such as appendiceal cancer, exist. Diagnosis is intricate, requiring diverse methods, with abdominal CT as a sensitive imaging tool. Conservative approaches are generally recommended for benign cases.
CONCLUSION
Appendiculocolonic fistulas, though rare, pose a clinical challenge due to their elusive symptoms. Primarily associated with benign conditions, notably abscess-forming appendicitis, or, as in our case, untreated acute appendicitis. This case underscores the role of abdominal CT in precise diagnosis, guiding treatment decisions based on the lesion's nature.

INTRODUCTION AND IMPORTANCE
The omphalomesenteric duct (OMD) is an embryonic structure that normally undergoes obliteration during embryonic development, typically not persisting after birth. Failure of complete or partial obliteration can result in a type of malformation known as OMD remnant.
CASE PRESENTATION
We report a case of a 24-year-old male patient diagnosed with bowel obstruction. Abdominal computed tomography (CT) scan revealed the presence of an adhesion band. During surgery, a fibrous band connecting from the umbilicus to the mesentery of terminal ileum was found and resected. Pathological investigation confirmed the presence of an OMD remnant fibrous band.
CLINICAL DISCUSSION
OMD remnant can manifest in different forms such as Meckel's diverticulum, umbilical polyp, OMD cyst, OMD fistula, and fibrous band, occurring in approximately 2 % of infants and often presenting symptoms in early childhood. These conditions rarely cause complications in adults. Complications may include obstruction, gastrointestinal bleeding, bowel perforation, and omphalitis which can present with symptoms such as abdominal pain, vomiting, melena, lack of defecation, umbilical discharge, and dermal manifestations. Diagnostic approaches vary depending on the type of OMD remnant and associated complications, but ultrasonography and CT scan can be useful. While asymptomatic OMD remnants generally do not require further intervention, surgical treatment is the main option for complicated and symptomatic cases.
CONCLUSION
OMD remnant is a rare condition in adults that can lead to complications. Given that obstruction is a common complication of OMD remnant, OMD remnant should be considered in the differential diagnosis of patients presenting with bowel obstruction.

A Meckel's diverticulum (MD) is an embryonic remnant of the omphalomesenteric duct. Although most MDs are usually asymptomatic, pediatric patients tend to present serious complications more frequently (4-25% of cases), mainly in digestive tract bleeding, intestinal obstruction, and perforation, which have a high potential to compromise the patient's life. An ectopic pancreas (EP) is pancreatic tissue found outside the pancreas, usually in the stomach, duodenum, and jejunum. It is typically asymptomatic but can increase the risk of complications in the MD. A clinical case of a female infant with an MD complicated with bleeding and ileo-ileal intussusception is presented, in which the histopathological finding of type 1 ectopic pancreatic tissue was also found based on the Heinrich classification, being an entity uncommon in our environment. An EP arising within an MD is infrequent, requiring clinical attention and timely preoperative diagnosis to prevent and treat associated severe complications. This continues to be a superior challenge for the clinician and requires a multidisciplinary team for comprehensive treatment.

BACKGROUND
Meckel's diverticulum is a common congenital malformation of the small intestine, with the three most common complications being obstruction, perforation, and inflammation. To date, only a few cases have been reported worldwide. In children, the clinical symptoms are similar to appendicitis. As most of the imaging features are nonspecific, the preoperative diagnosis is not precise. In addition, the clinical characteristics are highly similar to pediatric acute appendicitis, thus special attention is necessary to distinguish Meckel's diverticulum from pediatric appendicitis. Patients with poor disease control should undergo laparoscopic exploration to avoid serious complications, including intestinal necrosis, intestinal perforation and gastrointestinal bleeding.
CASE SUMMARY
This report presents three cases of appendicitis in children combined with intestinal obstruction, which was caused by fibrous bands (ligaments) arising from the top part of Meckel's diverticulum, diverticular perforation, and diverticular inflammation. All three patients, aged 11-12 years, had acute appendicitis as their initial clinical presentation. All were treated by laparoscopic surgery with a favorable outcome. A complete dataset including clinical presentation, diagnostic imaging, surgical information, and histopathologic findings was also provided.
CONCLUSION
Preoperative diagnosis of Meckel's diverticulum and its complications is challenging because its clinical signs and complications are similar to those of appendicitis in children. Laparoscopy combined with laparotomy is useful for diagnosis and treatment.

A 22-year-old female patient with a recent hospitalization for gastrointestinal bleeding presented with recurrent hematochezia and a positive shock index. Previous investigations, including endoscopy and wireless small bowel capsule, were non-diagnostic. CT angiography revealed extravasation in the ileum. Initial tests like technetium-99m scintigraphy and ileocolonoscopy were negative. Repeat wireless small bowel capsule identified a partially ulcerated polypoid mass in the distal ileum. At surgical exploration, an intussuscepted Meckel's diverticulum was identified and resected. A histopathologic examination confirmed the diagnosis. Meckel's diverticulum is a rare cause of gastrointestinal bleeding in adults. Preoperative diagnosis can be challenging. Reports of a polypoid morphology are very scarce in indexed literature and mostly derive from investigation with device-assisted enteroscopy. We report this extremely rare finding at capsule endoscopy to raise clinician awareness and to discuss diagnostic difficulties associated with similar cases, such as the negative scintigraphy result and the optimal timing of repeat capsule endoscopy.

The vitellointestinal duct (VID) is an embryological remnant of the vitelline duct, a structure that connects the developing fetus to the yolk sac and is responsible for the nutritional support of the fetus during the early embryological days. The VID usually gets obliterated by the fifth to ninth week of gestational age after the establishment of placental nutrition. The patent VIDellointestinal duct is a relatively rare congenital condition that occurs in approximately 2% of the general population, with the most common presentation being Meckel's diverticulum. Complete patency is rarer, occurring in 0.1% of the general population. The complete persistence of the VID results in enterocutaneous fistula, and the presentation may vary, ranging from cutaneous manifestations like skin lesions, granulomas, abscesses, or umbilical discharge to abdominal symptoms including acute abdominal pain and hematochezia. Some patients are even asymptomatic and are detected incidentally. We present a rare case of complete patency of the VID in a 30-year-old adult male presenting with acute periumbilical pain. Imaging findings guided the diagnosis, and surgical resection with histopathological examination further confirmed the condition.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. Torsion is a rare complication of MD with only 48 cases described in the English literature to date. We describe a case of a 22-year-old male who presented to the emergency department with lower abdominal pain. Pre-operative computed tomography scan suggested a torted MD. This was confirmed on diagnostic laparoscopy and managed with segmental resection of the MD and a concurrent appendicectomy. Histopathology confirmed torsion of MD and a normal appendix. The patient recovered well without any complications. Torsion occurs invariably with giant MD defined as a length of >5 cm. Surgical options for MD include diverticulectomy, wedge resection and segmental resection via laparoscopic or open approach. The rate of pre-operative diagnosis remains low but with advances in imaging and awareness of this condition, this is likely to increase with time.
