A Miraculous Save: Gangrenous Bowel and Meckle's Diverticulum With Acute Superior Mesenteric Artery Thrombosis.

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.

Idiopathic Omental Infarction Presenting With Recurrent Abdominal Pain.

Omental infarction is a rare cause of acute abdominal pain, and its rarity is mainly due to its relatively rich blood supply by multiple collateral vessels. It usually presents with right lower quadrant pain, as left-sided torsion is infrequent and is usually diagnosed intraoperatively. Since omental infarction is frequently diagnosed by CT scan, conservative management should be considered in most patients to avoid subjecting the patients to unnecessary surgical intervention. We present a rare case of idiopathic omental infarction in which the patient was initially radiologically diagnosed with Meckel's diverticulitis but was later found to have omental infarction on diagnostic laparoscopy.

Divertículo de Meckel: un hallazgo incidental / Meckel's diverticulum: an incidental finding

RESUMEN Fundamento: el divertículo de Meckel es una anomalía congénita con una baja incidencia y prevalencia. La mayoría de los pacientes que lo presentan son asintomáticos y son diagnosticados de forma incidental, sin embargo, alrededor del 2 % de los individuos desarrollan una complicación a lo largo de su vida, pero como estas tienden a disminuir conforme avanza la edad, es muy rara diagnosticarla en adultos. Objetivo: describir la presentación de un divertículo de Meckel en paciente adulto hallado de forma incidental durante la autopsia. Presentación del caso: paciente masculino de 66 años de edad, que al realizarle el estudio autópsico se revela la presencia de un saco diverticular a 62 cm de la válvula ileocecal, que al estudio histológico con hematoxilina y eosina permitió la observación de áreas de mucosa gástrica ectópica. Conclusiones: el divertículo de Meckel es una anomalía congénita que se localiza con frecuencia a 60 cm de la válvula ileocecal, en el borde antimesentérico; 50 % de ellos contienen tejido ectópico y su diagnóstico se realiza en la mayoría de los casos de forma incidental.

ABSTRACT Background: Meckel's diverticulum is a congenital anomaly with a low incidence and prevalence. The majority of patients who present it are asymptomatic and are diagnosed incidentally, however about 2% of individuals develop a complication throughout their lives, but as these tend to decrease as age progresses, it is very rare to diagnose it in adults. Objective: to describe the presentation of a Meckel diverticulum in an adult patient found incidentally during the autopsy. Case report: a 66-year-old male patient who, upon performing the autopsy study, revealed the presence of a diverticular sac 62 cm from the ileocecal valve, which revealed the presence of areas of ectopic gastric mucosa in the histological study with hematoxylin and eosin. Conclusions: Meckel's diverticulum is a congenital anomaly that is frequently located 60 cm from the ileocecal valve, on the anti-mesenteric edge; 50% of them contain ectopic tissue; and its diagnosis is made in most cases incidentally.

Inverted Meckel's Diverticulum: Rare Etiology of an Intestinal Obstruction.

Acute gastrointestinal obstruction can have a varied spectrum of clinical presentation and etiologies. It has been studied in detail and the management criteria have been well defined for the most part in our era. The etiologies are usually well defined. However, acute small bowel obstruction (SBO) due to intussusception caused by an inverted Meckel's diverticulum is a rare phenomenon that is often times missed on initial presentation and/or consequently until resected and visualized on pathological examination. We present a case of a 34-year-old presenting with symptoms and signs of acute intestinal obstruction and radiographic exam showing ileo-ileal intussusception. The patient failed to improve initially following conservative management and was taken to the operating room for small bowel resection which then revealed an inverted Meckel's diverticulum.

An Unusual Case of Small Bowel Volvulus.

Small bowel volvulus is a rare and life threatening surgical emergency. Nearly 75% of volvulus occurs in colon and 25% occurs in small bowel. Small bowel volvulus is abnormal twisting of bowel loops around the axis of its own mesentry leading to twisting and occlusion of mesenteric vessels causing intestinal obstruction, venous engorgement, gangrene and perforation. Small bowel volvulus is more common in neonates and young adults and very rare in adults. We are reporting a first case of small bowel volvulus and gangrene caused by herniation of ovarian cyst through mesenteric defect and twisting of small bowel around the axis of ovarian cyst leading to closed loop obstruction, small bowel volvulus and gangrene. Outcome of the disease is mainly based on the early diagnosis and intervention. Mortality is about 5.8 - 8% in nongangrenous SBV which increases drastically to 20 - 100% in gangrenous bowel.

[Adenocarcinoma mucoproductor in Meckel's diverticulum. Case report and review]. / Adenocarcinoma mucoproductor en un divertículo de Meckel. Reporte de caso y revisión del tema.

BACKGROUND: Meckel's diverticulum is the most common congenital anomaly in the small intestine, which results from incomplete obliteration omphalomesenteric duct, usually the diagnosis is incidental, rarely reaching with bleeding, obstruction, diverticulitis or in rare cases a neoplasm. Clinic case: 67 year old woman that started her condition with urinary symptoms (dysuria, frequency, bladder tenesmus and pushing), within the study protocol a cystogram was performed and demonstrated a defect in the bladder dome edges with compression effect, the computed tomography reported a bladder infiltrating hypodense lesion, which is decided to resect finding Meckel's diverticulum with a tumor that infiltrates the bladder dome, the histopathological confirmed the diagnosis shown free edges but insufficient, which need a reintervention to increase margins; all the extension studies shown without tumor activity. CONCLUSIONS: Mucoproductor adenocarcinoma derived from a Meckel's diverticulum is a clinical entity that because of its nonspecific symptomatology and variability of presentation, is diagnosed incidentally on radiological images. The disease has a high mortality rate and a low prevalence.

Antecedentes: el divertículo de Meckel es la anomalía congénita más frecuente en el intestino delgado, que resulta de la obliteración incompleta del conducto onfalomesentérico; su diagnóstico suele ser incidental, pocas veces con sangrado, obstrucción, diverticulitis o en casos raros una neoplasia. Caso clínico: paciente femenina de 67 años de edad, que inició su padecimiento con síntomas urinarios (disuria, polaquiuria, pujo y tenesmo vesical). El cistograma demostró: defecto en el domo de la vejiga, bordes irregulares y efecto de compresión. La tomografía computada reportó: vejiga con lesión hipodensa infiltrante en el domo vesical, al resecarla se encontró un divertículo de Meckel con un tumor infiltrante; el estudio histopatológico confirmó el diagnóstico y demostró los bordes libres; todos los estudios de extensión resultaron sin actividad tumoral. Conclusiones: el adenocarcinoma mucoproductor derivado de un divertículo de Meckel es una entidad clínica que debido a sus síntomas inespecíficos y variabilidad de presentación sólo se diagnostica por lo que se aprecia en las imágenes radiológicas. Este adenocarcinoma tiene un alto índice de mortalidad pero baja prevalencia.

A Case of Gastro-Colic Fistula due to Ectopic Gastric Mucosa and its 99mTcO4 Scan Findings / 대한핵의학회잡지

We report a case of gastro-colic fistula caused by ectopic gastric mucosa developed at transverse colon. Fistula was detected by colonofiberscopy. And fistulous tract was proved by barium enema. Meckel's diverticulum scan finding was similar to that of GI bleeding; e.g. injected radioactivity was secreted into the lumen and moved along the lumen. There was no bleeding. And there was no diverticulum in the colon. Absence of diverticular pouch may explain this unusuaal GI bleeding-like scan finding rather than focal collection of radioactivity, which is typical of ectopic gastric mucosa found in the Meckel's diverticulum. Ectopic gastric mucosa was confirmed by colonfiberscopic biopsy. We suggest GI bleeding-like pictures should be included differential diagnosis of Tc-99m-O4 (ectopic gastric mucosa or Meckel's diverticulum) scan.
