Review
BACKGROUND
Meckel Diverticulum [MD), a common congenital anomaly of the gastrointestinal tract, poses a dilemma when incidentally encountered during surgery. Despite historical descriptions and known complications of symptomatic MD, the decision to resect an incidental MD (IMD) lacks clear guidelines. This study aims to assess whether resecting IMDs is justified by synthesizing evidence from studies published between 2000 and 2023. Factors influencing this decision, such as demographic risks, surgical advancements and complications, are systematically examined.
METHODS AND MATERIAL
Following the PRISMA 2020 guidelines, this review incorporates 42 eligible studies with data on outcomes of asymptomatic MD management. Studies, both favoring and opposing resection, were analyzed.
RESULTS
Considering complications, malignancy potential, and operative safety, the risk-benefit analysis presents a nuanced picture. Some authors propose conditional resection based on specific criteria, emphasizing patient-specific factors. Of 2934 cases analyzed for short- and long-term complications, the morbidity rate was 5.69%. Of 571 cases where mortality data were available, all 5 fatalities were attributed to the primary disease rather than IMD resection.
CONCLUSION
The sporadic, unpredictable presentation of IMD and the variability of both the primary disease and the patient make formulation of definitive guidelines challenging. The non-uniformity of complications reporting underscores the need for standardized categorization. While the balance of evidence leans towards resection of IMDs, this study acknowledges the individualized nature of this decision. Increased safety in surgery and anesthesia, along with better understanding and management of complications favor a judicious preference for resection, while taking into account patient characteristics and the primary disease.

A retrospective study in patients who underwent video capsule endoscopy (VCE) between 2006 and 2016 was conducted in the Clinic for gastroenterology and Hepatology, University Clinical Center of Serbia. A total of 245 patients underwent VCE. In 198 patients the indication was obscure gastrointestinal bleeding (OGIB), with 92 patients having overt and the other 106 occult bleeding. The remaining 47 patients underwent VCE due to suspected small bowel (SB) disease (i.e., Von Hippel-Lindau syndrome, familial adenomatous polyposis, Peutz Jeghers syndrome, Crohn's disease, prolonged diarrhea, abdominal pain, congenital lymphangiectasia, protein-losing enteropathy, tumors, refractory celiac disease, etc.). VCE identified a source of bleeding in 38.9% of patients (in the obscure overt group in 48.9% of patients, and in the obscure occult group in 30.2% of patients). The most common findings were angiodysplasias, tumors, Meckel's diverticulum and Crohn's disease. In the smaller group of patients with an indication other than OGIB, 38.3% of patients had positive VCE findings. The most common indication is OGIB, and the best candidates are patients with overt bleeding; patients with IBD should be evaluated in this setting.

INTRODUCTION
and Importance: Meckel's diverticulum is a rare congenital condition often detected incidentally. Meckel's diverticulum, a rare disease, may result in acute intestinal obstruction and is frequently misdiagnosed. This study aims to report a case of acute intestinal obstruction due to Meckel's diverticulum.
CASE PRESENTATION
A 61-year-old Javanese man was admitted to the emergency room with a history of constipation, nausea, vomiting, and abdominal pain. Physical examination showed abdomen distention, tenderness in the lower quadrant, and hyperactive bowel sound. Rectal examination found that the rectal ampulla was collapsed. A plain abdominal Radiograph showed small bowel dilatation and air-fluid levels. The patient was diagnosed with small bowel obstruction due to suspected left-sided colon cancer and taken up for exploratory laparotomy.
CLINICAL DISCUSSION
On exploration, Meckel's diverticulum measuring 3.5 cm in length and with a 2 cm base was found about 70 cm proximal to the Bauhin valve; the thin part formed a band that entangled the small bowel. Ileo-ileal resection anastomosis was performed.
CLINICAL DISCUSSION
Meckel's diverticulum is an intestinal pouch caused by incomplete obliteration of the vitelline duct during gestation. This condition affects 2 % of the population and is within 2 feet of the Bauhin valve. The mesodiverticular band was found to be the source of the bowel obstruction. Surgical resection is required for complicated diverticulum.
CONCLUSION
Meckel's diverticulum can be difficult to diagnose and require a higher level of suspicion. Although Meckel's diverticulum is uncommon in adults, it should be considered a cause of small bowel obstruction.

Perforation of Meckel's diverticulum by a foreign body is rare, but when it occurs, it can mimic acute appendicitis, leading to diagnostic challenges. We present a case of a 45-year-old male initially diagnosed with acute appendicitis, but intra-operative exploration revealed a perforated Meckel's diverticulum with a fish bone. Meckel's diverticulum perforation remains diagnostically elusive, highlighting the need for intra-operative vigilance in cases of inconsistent findings like the presence of bilious fluid in the abdominal cavity. This case report underscores the importance of considering perforated Meckel's diverticulum in the differential diagnosis of right iliac fossa pain and the necessity of surgical exploration for atypical presentations to ensure timely diagnosis and appropriate management.

Meckel's diverticula are one of the most common gastrointestinal anomalies, yet mesodiverticular bands are rare. The treatment of these bands commonly requires surgery. A healthy patient in his 20s presented to the emergency department with a 1 day history of acute onset abdominal pain. Computed tomography imaging was consistent with volvulus of the large intestine. In the operating room, the patient was noted to have a band between the ileal mesentery and tip of a Meckel's diverticulum, consistent with a mesodivertiular band, through which cecum had volvulized. The patient underwent resection. The patient recovered without major complications. Mesodiverticular bands are rare, but may present as hemoperitoneum, small bowel obstruction, or volvulus. Pre-operative diagnosis of a mesodiverticular band is often difficult and they are most commonly diagnosed intraoperatively. Treatment should include surgery and may include simple lysis of the band, bowel resection, or more extensive resection if other pathology is present.

International Journal of Surgery Case... Jun 2024Paraduodenal hernias are difficult to diagnose due to their unusual presentation. Herein, five new cases are added to the literature.
INTRODUCTION AND IMPORTANCE
Paraduodenal hernias are difficult to diagnose due to their unusual presentation. Herein, five new cases are added to the literature.
CASE PRESENTATION
Four male and one female child complained of paraduodenal hernias, two on the right side and three on the left side. The intestinal part that herniated inside the hernia sac was also malrotated in four patients. One patient had Meckel's diverticulum with a herniated intestine. One infant had extrahepatic biliary disease, a single atrium, polysplenia, intestinal malrotation, and a left paraduodenal hernia. Exploratory labarotomy was done for reduction of the intestine, reorientation, and repair of hernia orifices.
CLINICAL DISCUSSION
Paraduodenal hernia is a component of malrotation. Cautious dissection of the hernia orifice is required to keep away from injuries to the inferior mesenteric vein or left colic artery in the course of the restoration of the left paraduodenal hernia. Also, the superior mesenteric vessels may be injured in the course of the restoration of the right paraduodenal hernia.
CONCLUSION
There is a correlation between the occurrence of PDH with malrotation. The diagnosis of malrotation can be made with an ultrasound abdomen; however, it is true that ultrasound cannot make a confirmed diagnosis in all patients. Once the diagnosis of a mesocolic hernia has occurred, surgical repair is mandatory by closure of the defect.

BACKGROUND
Meckel's diverticulum (MD) is the most common congenital defect of the gastrointestinal tract, occurring in about 1% to 2% of population. Most MD are rarely symptomatic, with presenting symptoms including diverticulitis, digestive tract hemorrhage and intestinal obstruction. The semblance of symptoms to enteritis and appendicitis makes preoperative diagnosis challenging. Current diagnosis of MD includes technetium-99m pertechnate scan, laparoscopic or intraoperative findings and examining surgical specimens. Here, we report that a double-balloon enteroscopy (DBE) improves the diagnosis accuracy of MD and presents high clinical application value.
CASE DESCRIPTION
A 12-year-old male patient was admitted to our hospital due to recurrent abdominal pain and black stools for more than half a year, recurrence for 2 days, accompanied by vomiting. The boy had anemic appearance, with periumbilical tenderness, and no mass was detected upon palpations. Past medical records revealed recurrent abdominal pain episodes thrice. Pre-surgery TcO-single-photon emission computed tomography/computed tomography (SPECT/CT) imaging was performed but did not reach the condition for diagnosis of MD. DBE was then performed and identified an upper ileum mass. After surgery, it was confirmed that the patient was an inverted MD, and the pathology showed gastric mucosa and pancreatic tissue. The patient recovered well after surgery and was discharged.
CONCLUSIONS
DBE is not widely used in the diagnosis of MD, but its accuracy is higher than that of radionuclide scanning imaging. In addition, several advantages such as hemostasis treatment, direct detection and observation of the diverticulum, and demarcation of the site and scope of the lesion prior to surgery brings high clinical application value.

Meckel's diverticulum is the most common congenital gastrointestinal defect with a prevalence of 2%. It is mostly asymptomatic and it rarely causes acute abdomen in adults. In this case report, a 28-year-old male with no previous abdominal surgery presented with clinical symptoms of small bowel obstruction. Surgery revealed a Meckel's diverticulum adherent to the abdominal wall, causing internal herniation with small bowel obstruction. The diverticulum was openly resected and no post-operative complications occurred. Laparoscopy seems safe, and surgical removal of the symptomatic Meckel's diverticulum is recommended.

BACKGROUND
The study aimed to analyze the characteristic clinical manifestations of patients with intestinal disease Meckel's diverticulum (MD) complicated by digestive tract hemorrhage. Moreover, we aimed to evaluate the value of double-balloon enteroscopy (DBE) in MD diagnosis and the prognosis after laparoscopic diverticula resection.
AIM
To evaluate the value of DBE in the diagnosis and the prognosis after laparoscopic diverticula resection for MD with bleeding.
METHODS
The study retrospectively analyzed relevant data from 84 MD patients treated between January 2015 and March 2022 and recorded their clinical manifestations, auxiliary examination, and follow-up after laparoscopic resection of diverticula.
RESULTS
(1) Among 84 MD patients complicated with hemorrhage, 77 were male, and 7 were female with an average age of 31.31 ± 10.75 years. The incidence was higher in men than in women of different ages; (2) Among the 84 MD patients, 65 (78.40%) had defecated dark red stools, and 50 (58.80%) had no accompanying symptoms during bleeding, indicating that most MD bleeding appeared a dark red stool without accompanying symptoms; (3) The shock index of 71 patients (85.20%) was < 1, suggesting that the blood loss of most MD patients was less than 20%-30%, and only a few patients had a blood loss of > 30%; (4) The DBE-positive rate was 100% (54/54), 99mTc-pertechnetate-positive scanning rate was 78% (35/45) compared with capsule endoscopy (36%) and small intestine computed tomography (19%). These results suggest that DBE and 99mTc-pertechnetate scans had significant advantages in diagnosing MD and bleeding, especially DBE was a highly precise examination method in MD diagnosis; (5) A total of 54 MD patients with hemorrhage underwent DBE examination before surgery. DBE endoscopy revealed many mucosal manifestations including normal appearance, inflammatory changes, ulcerative changes, diverticulum inversion, and nodular hyperplasia, with ulcerative changes being the most common (53.70%). This suggests that diverticular mucosal ulcer was the main cause of MD and bleeding; and (6) Laparoscopic dissection of diverticulae was performed in 76 patients, The patients who underwent postoperative follow-up did not experience any further bleeding. Additionally, follow-up examination of the 8 cases who had declined surgery revealed that 3 of them experienced a recurrence of digestive tract bleeding. These findings indicate that laparoscopic diverticula resection in MD patients complicated by bleeding had a favorable prognosis.
CONCLUSION
Bleeding associated with MD was predominantly observed in male adolescents, particularly at a young age. DBE was a highly precise examination method in MD diagnosis. Laparoscopic diverticula resection effectively prevented MD bleeding and had a good prognosis.

Meckel's diverticulum is the most prevalent congenital anomaly of the gastrointestinal tract, identified in 2% of the population according to autopsy studies. Most patients remain asymptomatic throughout their lives and are typically diagnosed when complications arise. The diagnosis can be challenging, but imaging is crucial for promptly identifying and distinguishing it from other conditions that have similar clinical manifestations. A 13-year-old male was admitted with a 5-day history of rectal bleeding. The patient continued to experience painless gastrointestinal bleeding, indicating the performance of a Tc-99m pertechnetate scintigraphy or Meckel's scan. Planar images revealed focal uptake within the right hemiabdomen, suggestive of the presence of a Meckel's diverticulum. Subsequent laparotomy surgery confirmed the presence of a Meckel's diverticulum located 50 cm from the ileocecal valve. Histopathological examination of the resected specimen confirmed Meckel's diverticulum with ectopic gastric mucosa. This patient with Meckel's diverticulum exhibited minimal abdominal symptoms, and there were no other complications such as intussusception, which could lead to bowel obstruction. Technetium-99m pertechnetate scintigraphy is a common method for evaluating children with unexplained gastrointestinal tract bleeding. SPECT/CT fusion imaging enables the simultaneous fusion of functional and anatomical information, preventing false-negative scintigraphy examinations. Its capability to precisely localize activity in abnormal structures contributes to accurate scan interpretation. Complications of Meckel's diverticulum are uncommon and pose a diagnostic challenge. Through comprehensive history-taking, physical examination, and nuclear imaging, the diagnosis can be identified, and surgical intervention can be performed to achieve the best possible outcome for the patient.
