The authors report a case of mesenchymal tumor (leiomyosarcoma) arising in a Meckel's diverticulum, with an history of digestive bleeding. Different kinds of Meckel's diverticulum tumors, their symptomatology and diagnostic difficulties are then discussed.
A case is reported of an asymptomatic intraluminal duodenal diverticulum (IDD) in a 21-year-old male patient with associated congenital abnormalities. During endoscopy for anemia an ostium in the duodenum was visualized, presumed to be the entry to an extraduodenal diverticulum. Upper gastrointestinal (UGI) barium examination showed, however, findings compatible with IDD. This diagnosis was supported by an abdominal computed tomographic (CT) examination. Surgical resection revealed a web in D2 with coexistent large IDD.
This 83-year-old patient was admitted to the emergency room after a sudden and abundant rectal bleeding without any other abdominal symptoms. The physical examination showed normal abdominal findings. However, digital rectal examination revealed dark red blood. Upper and lower endoscopic examination did not show an active bleeding source. A diagnosis of an acute lower gastrointestinal bleeding probably originating from a diverticulum was made. The patient was dismissed two days later without any signs of further bleeding. However, the same day he was readmitted again because of acute rebleeding. Emergency colonoscopy was not conclusive because of massive hemorrhage. Angiography of the abdominal arteries was performed which showed marked active bleeding in the coecal region. Ileocoecal resection was performed and histopathological examination showed a solitary coecal diverticulum.
The diagnosis of a bleeding Meckel's diverticulum was made by angiography in a 71 year old man who presented with melena and hemorrhagic shock. Emergent angiographic examination revealed an extravasation of contrast media from the ileal artery, which suggested a bleeding from the Meckel's diverticulum. The case illustrates the utility of selective angiography in case of gastrointestinal hemorrhage, where the lesion is beyond the range endoscopy.
The authors present an account of a large Meckel's diverticulum in a 17-year-old boy as the cause of chronic intermittent pain in the umbilical area, rare at this age, with development of acute inflammatory abdomen. During an emergency operation resection of the diverticulum was performed with 10 cm of the adjacent ileum and anastomosis of the ileum end-to-end. The patient recovered after surgery per primam intentionem and is free from complaints. The authors draw attention to the difficult preoperative diagnosis of this disease as well as to possible contemporary diagnostic and therapeutic possibilities.
BACKGROUND: Laparoscopic techniques are increasingly being utilized to diagnose and successfully manage intestinal obstruction. CASE REPORT: We describe a patient who presented with intestinal obstruction following a recent abdominal hysterectomy. The obstruction was caused by entrapment of a segment of small bowel containing a Meckel's diverticulum within a pouch formed by the peritoneal layer following mass closure of the abdominal wound. DISCUSSION: We discuss the literature on the abdominal wound closure technique. The role of laparoscopy in dealing with intestinal obstruction is reviewed briefly. We have also summarized the management of an incidental Meckel's diverticulum found at laparoscopy.
An uncommon complication of the sigmoid diverticulitis personally observed is described. A woman, 59 years old, presented a septic shock caused by perforated sigmoid diverticulum into the space of Retzius. The diagnosis was carried out by an X-ray of the abdomen that suspected the presence of air in the retroperitoneum and then by barium enema showing a perforation of the sigmoid colon. During laparotomy a perforation of sigmoid diverticulum in to the space of Retzius was observed. So the space of Retzius was opened and then pus and watery exudate containing bubbles of gas were found extended also to the retroperitoneum and the right abdomen wall. The patient was submitted to a sigmoid resection; bowel continuity was restored by circular stapled anastomosis and a temporary colostomy was made. Some drainages were placed into the space of Retzius, into the retroperitoneum and into the peritoneal cavity. Nevertheless the patient died because of the septic shock and the postoperative MOF.
A woman, who discharged pus at the time of intercourse, was diagnosed to have a urethral diverticulum by combination of urethroscope and MRI. MRI provided clear view of the diverticulum in terms of the relationship with the surrounding organs.
We report a case of urethral diverticulum with a calculus in a 52-year-old female. She had suffered from transverse myelopathy (flaccid paralysis) as a result of multiple sclerosis. She presented with total incontinence and urinary tract infection that did not respond to antibiotic therapy. We found a urethral diverticulum calculus by X-ray imaging and urethroscopy. Transvaginal urethral diverticulectomy with removal of stone was carried out without any complications. The removed stone was 35 x 31 x 19 mm in size and was composed of magnesium ammonium phosphate and calcium phosphate.
We present a case of spontaneous rupture of bladder diverticulum three years after postoperative whole pelvic irradiation (50.4 Gy) for carcinoma of the uterine cervix. The patient had suffered from a neurogenic bladder after hysterectomy, but excretory urography revealed no abnormalities. Bladder diverticulum was found two years later. Spontaneous rupture of the urinary bladder is one of the late complications associated with radiotherapy, although it is very rare. Postoperative neurogenic bladder may also be associated with rupture. We should be aware of this rare complication in patients who receive pelvic irradiation.
A case of intrapancreatic duodenal diverticulum is presented and the possibility of pancreatitis is considered. A digital manoeuvre is described for the non-invasive location of a large diverticulum in case where Kocher's manoeuvre is insufficient. The usefulness of surgery as a mean of preventing what may prove dramatic complications is recognised.
Ventricular diverticulum are small outpouchings, in the cardiac wall, which are mostly described as a part of malformation syndromes. This finding is infrequent in asymptomatic patients with no pathology in the thoraco abdominal line. The case we present shows a diverticulum in the cardiac apex in a male patient with no cardiological clinic manifestations and with an abnormal electrocardiogram. At present, magnetic resonance is the best diagnostic test, for this kind of malformation, and is also the most reliable in the follow-up of these patients.
We report the case of a 65-year-old woman with a 10-year history of dysphagia, regurgitation, cough, and 10-kg weight loss caused by an epiphrenic diverticulum associated with esophageal achalasia managed with a laparoscopic approach. A preoperative barium swallow showed a dilated sigmoid esophagus with a 6-cm epiphrenic diverticulum. Esophageal manometry confirmed the absence of peristalsis in the esophageal body. We performed a laparoscopic diverticulectomy and a 7-cm distal esophageal myotomy with a Dor fundoplication. The postoperative course was uneventful. On the third postoperative day a barium swallow showed no leak, and the patient started oral intake. She was discharged home 5 days after the operation free of symptoms and tolerating a soft diet. Sixteen months after surgery, she was asymptomatic and had gained 8 kg. A barium swallow showed a normal-size esophagus with regular emptying. We reaffirm the feasibility, safety, and efficacy of the laparoscopic diverticulectomy and distal myotomy with Dor fundoplication to manage epiphrenic diverticula resulting from esophageal achalasia.
The urethral diverticulum has many varied presentations; therefore, ultimate diagnosis may be difficult. Until recently, radiographic evaluation was difficult to perform, was uncomfortable for the patient, and had poor sensitivity. The increasingly widespread use of magnetic resonance imaging coupled with heightened awareness of the problem has enhanced the overall detection of urethral diverticula. Management is still primarily surgical and entails proper anatomical identification of the defects that cause the diverticulum, so subsequent reconstruction can be performed easily and with minimal morbidity.
Meckel's diverticulum is the most common congenital abnormality of the small intestine. A case of Meckel's diverticulum duplication is described, believed to be the first report of this kind in the literature.
A 21-year-old male presented with episodes of paroxysmal tachycardia mediated via a concealed posteroseptal accessory pathway. He was also found to have a diverticulum of the coronary sinus. However, successful radiofrequency ablation was achieved only endocardially under the mitral annulus and not within the diverticulum.
An 87-year-old man presented with hematuria and dysuria. An endoscopic examination revealed a bladder mucosa which was almost entirely occupied by diverticula. On the left lateral wall of the bladder there was a huge diverticulum which contained a 12 cm mass extending beyond the bladder wall in the extraperitoneal tissues. Upon histological examination the mass proved to be a carcinosarcoma which was composed by a squamous carcinoma and a sarcoma resembling a malignant fibrous histiocytoma. The two components, i.e. carcinomatous and sarcomatous, were separated by a sharp collision border and no intermingling was ever noted. The epithelial component showed immunoreactivity for cytokeratin and EMA, while the mesenchymal component was diffusely reactive for vimentin, alpha-1-antitrypsin and lysozime. Both components were reactive for galectin-3, whereas S100, desmin and smooth muscle actin were negative. This is the fourth reported case of carcinosarcoma originating in a bladder diverticulum.
Left posteroseptal accessory pathways have been described inside coronary sinus diverticula. We here describe the case of a patient who was suffering from recurrent episodes of paroxysmal supraventricular tachycardia and had a concealed accessory pathway located in the left anterolateral margin of the mitral annulus and a left posterior coronary sinus diverticulum associated with an aneurysmal coronary sinus vein. In the electrophysiological study, an orthodromic supraventricular tachycardia was induced and reproduced. We performed a successful radiofrequency ablation of the pathway. Our case provides evidence of the coexistence of concealed accessory pathways capable of sustaining orthodromic tachycardia coexisting with a bystander posterior coronary sinus diverticulum and aneurysmal coronary sinus vein.
