Endoscopic diagnosis of bleeding Meckel's diverticulum in a multivisceral transplant recipient.

Small bowel transplantation has become a life-saving procedure for patients with intestinal failure who fail conventional therapy. Meckel's diverticulum is a rare cause of occult gastrointestinal bleeding that has not been reported in patients receiving intestinal allografts. We report a case in which transplantation of an asymptomatic Meckel's diverticulum as part of a multivisceral allograft led to intestinal bleeding requiring surgical intervention. Endoscopy identified the actual bleeding diverticulum. Diverticulectomy at the time of transplant was not performed due to the difficult operative course, and the need for frequent surveillance ileoscopy, which would be performed across a fresh intestinal anastomosis. The patient underwent resection of the diverticulum, along with 40 cm of ileum, and did not experience further bleeding.

Congenital diverticulum of the right ventricle associated with coarctation of aorta, atrial and ventricular septal defect and ductus.

Congenital right ventricular muscular diverticula are extremely rare and are usually associated with other congenital cardiac anomalies, (in half of the cases tetralogy of Fallot). They functionally behave like an accessory ventricular chamber which contracts synchronously with the normal ventricles. Less than 30 patients with a right ventricular diverticulum have been reported in literature. An apical right ventricular diverticulum occurs in patients with thoraco-abdominal midline defects or abnormalities of the cardiac position([1]). However, an antero-superior diverticulum is usually associated with other congenital cardiac defects, such as a ventricular septal defect, tetralogy of Fallot, double outlet right ventricle and pulmonary stenosis([2--9]). We report an 11-year-old boy with an antero-superior diverticulum of the right ventricle associated with a coarctation of aorta, ductus arteriosus, and atrial and ventricular septum defects. To the best of our knowledge, such an association has not been reported before.

[Endoscopic removal of an intraluminal duodenal diverticulum in an adult with upper abdominal pain].

We report here on a 44-year-old previously healthy patient with a two-year history of intermittent upper abdominal pain. In the outpatient gastroduodenoscopy and X- ray examinations of the small intestine an intraluminal duodenal diverticulum was suspected. Clinical examination and laboratory tests did not show any abnormal findings. In order to exclude other causes for the patient's complaints coloscopy, ERP and MRCP were performed. The latter was done because the bile duct could not be intubated in the ERCP due to the altered anatomy. By use of endoscopic ultrasound a mucosal duplication was demonstrated and thus the diagnosis confirmed. Subsequently, the diverticulum sac was sliced by argon plasma coagulation. The postinterventional course was without complications and the patient was without symptoms afterwards. The intraluminal duodenal diverticulum is a rare differential diagnosis of pain in the upper abdomen. The diverticulum should be endoscopically removed if other causes for abdominal pain have been ruled out and possibly associated malformations have been excluded.

Migrating calcified enterolith and chronic anemia: an unusual case presentation of a Meckel's diverticulum.

Meckel's diverticulum is the most common congenital anomaly of the small intestine, occurring in about 2 % of the population. The most common complications associated with a Meckel's diverticulum include obstruction, bleeding, and inflammation (7, 9, 11, 18-20). The estimated lifetime risk of developing symptoms with a Meckel's diverticulum is 4-6 % (16), with the risks of complications decreasing with age. Stones within Meckel's diverticulum are recognized as a rare complication in the adult population (13,15). However, it has not been reported in the pediatric age group. The authors describe a 19-month-old male who presented with intermittent abdominal pain and vomiting, chronic microcytic anemia and a calcified stone in the lower abdomen, who was found to have a Meckel's enterolith.

Endotherapy of Zenker's diverticulum using the needle-knife technique: long-term follow-up.

BACKGROUND AND STUDY AIMS: Endotherapy of Zenker's diverticulum by mucomyotomy of the bridge between the diverticulum and the esophageal lumen has been introduced as a promising alternative to surgical techniques. However the data on long-term clinical outcome are limited. After poor results in four patients treated by argon plasma coagulation, we studied the efficacy and the long-term outcome of dissection using a needle-knife in a consecutive series of patients. PATIENTS AND METHODS: Between December 2001 and November 2004, 31 consecutively treated symptomatic patients (18 men; median age 69 years; range 52-92) with Zenker's diverticulum were enrolled into this retrospective study. In all cases mucomyotomy was performed with a needle-knife with the patient under conscious sedation. The procedure was repeated in the case of incomplete relief from dysphagia or of recurrent symptoms during follow-up. All patients completed questionnaires on the frequency and severity of dysphagia, using a numeric analogue scale, ranging from 0 (never/none/excellent) to 10 (each time of swallowing/very severe/very bad). RESULTS: Endoscopic mucomyotomy was achieved in all 31 patients, with initial symptomatic improvement. Repeat treatment was required in 10 patients after a mean of 5.3 months, due to recurrence of symptoms. During a mean follow-up period of 26 months (range 14-49), 26 patients (84%) had long-term success of variable degree (65% with no or minimal remaining symptoms); four patients (13%) had insufficient relief and wanted a repeat treatment; and one patient (3%) underwent surgery. The success rate in the entire group was 84% (26/31) including those with repeat treatment, and 61% (19/31) if only success following a single treatment session was counted. Minor complications such as subcutaneous or mediastinal emphysema were observed in 23% and were conservatively managed. There were no major complications. CONCLUSIONS: A single needle-knife mucomyotomy procedure can achieve long-term symptomatic improvement in about two out of three cases of Zenker's diverticulum. The success rate can be increased to above 80% by repeated sessions. Minor complications occur frequently but they can be conservatively managed. Major complications were not observed. Further long-term studies are warranted to elucidate the role of endoscopy as a definitive single treatment, with determination of prognostic parameters for a successful long-term outcome.

[Lateral pharyngeal diverticulum as a cause of superior laryngeal nerve neuralgia].

Superior laryngeal neuralgia was first described at the turn of the century by Avellis. In absence of accompanying disease in the organs adjacent to the nerve, idiopathic neuralgia is the most likely diagnosis. A 63-year-old man presented with left superior laryngeal neuralgia. Endoscopy revealed no pathological findings. Barium examination of the pharynx applying a modified Valsalva's manoeuvre revealed a small (0.5 cm) lateral pharyngeal diverticulum. 21 months after successful surgical removal the patient remains symptom-free. In the case of a 65-year old woman with left superior laryngeal neuralgia, barium examination revealed a lateral pharyngeal diverticulum at the same position between the hyoid-bone and the upper margin of the thyroid cartilage. The symptoms disappeared spontaneously. This is the first case of this particular kind of lateral pharyngeal diverticulum described in the literature. The explanation for the obstinate superior laryngeal neuralgia caused by such a small diverticulum must be sought in its immediate neighborhood to the superior laryngeal nerve.

[Meckel lithiasis. A rare complication of a Meckel's diverticulum].

HISTORY AND CLINICAL FINDINGS: Acute abdominal pain, radiating to the right and left lower abdomen with pain on abdominal pressure developed in a 67-year-old man. There were questionable signs of peritonitis. INVESTIGATIONS: Leukocytosis (20,000/microliter) and a high level of C-reactive protein (177 mg/l) were found. Ultrasound and computed tomography were suggestive of a stone in a Meckel's diverticulum. TREATMENT AND COURSE: This diagnosis was confirmed at surgery and there were no other abnormalities. The diverticulum with stone was resected and the patient made an uneventful recovery. CONCLUSIONS: A stone in a Meckel's diverticulum, although rare, should be included in the differential diagnosis of acute abdomen with radiological evidence of calcification in the lower abdomen. The possibility of this rare complication raises the question of prophylactic resection of Meckel's diverticulum, even when it is merely an incidental finding.

Endoscopic treatment of Zenker's diverticulum with an oblique-end hood attached to the endoscope.

BACKGROUND: The feasibility and efficacy of incision of the septum between the pharyngoesophageal (Zenker's) diverticulum and the esophagus with a flexible endoscope and needle-knife have been demonstrated. Exposure of the septum remains a critical element of the procedure. This is a report of a technical improvement in this technique: use of a transparent oblique-end hood attached to the tip of the endoscope. METHODS: Ten patients (10 men, age range 67-87 years) with Zenker's diverticulum were treated. With the aid of an oblique-end hood attached to the tip of the endoscope, the septum between the Zenker's diverticulum and esophagus was incised with pure coagulation current. A 10F nasogastric tube was left in place for 48 hours after the procedure to provide nutrition. Thereafter, oral intake was progressively resumed. RESULTS: Complete incision of the septum was achieved in a single session in all cases. Bleeding or perforation did not occur in this small series. Complete relief of dysphagia was reported by all patients during follow-up that ranged from 2 to 12 months. CONCLUSIONS: With the use of the oblique-end hood attached to the tip of the endoscope, incision of Zenker's diverticulum is simplified and can be performed as a single-session procedure.

Spontaneous haemoperitoneum secondary to a Meckel's diverticulum.

Meckel's diverticulum is a relatively common gastrointestinal entity which occasionally causes complications. Meckel's diverticulum is classically described to mimic acute appendicitis when inflamed as well as being a cause of unexplained luminal gastrointestinal bleeding. An unusual cause of spontaneous non traumatic haemoperitoneum found during surgery performed for a suspected acute appendicitis in a 22-year old female is described. The patient was found to have a significant haemoperitoneum due to a bleeding serosal vessel of a Meckel's diverticulum. The diverticulum was routinely excised. It was macroscopically and histologically devoid of inflammation. The bleeding vessel was not found to be abnormal or part of an arteriovenous malformation.

Unusual scintigraphic presentation of a shifting Meckel's diverticulum.

A Tc-99m red blood cell (RBC) study in a child with acute gastrointestinal bleeding of unknown origin suggested Meckel's diverticulum because of free pertechnetate uptake in the ectopic gastric mucosa. This finding has not been reported in the literature. A scan with Tc-99m pertechnetate then demonstrated a focal area of uptake with an unusual pattern of abdominal shifting consistent with a Meckel's diverticulum. A large Meckel's diverticulum containing gastric mucosa was found at surgery. A shifting pattern of focal uptake on a meckelogram study should be included among the diagnostic criteria for Meckel's diverticulum.

Meckel's diverticulum. Internal hernia and adhesions without gastrointestinal bleeding--ultrasound and scintigraphic findings.

The results from an ultrasound study performed on an 11-year-old boy, who had several weeks of intermittent abdominal pain, showed a nonperistaltic loop of bowel near the umbilicus, which suggested either an internal hernia or a diverticulum. Tc-99m pertechnetate imaging showed a focal collection near the umbilicus, which was consistent with a Meckel's diverticulum. No evidence was found of gastrointestinal bleeding. Exploratory laparotomy showed a Meckel's diverticulum near the terminal ileum and attached to the anterior abdominal wall close to the umbilicus. Small bowel had herniated through the loop formed by the terminal ileum and the diverticulum.

Endoscopic stapled diverticulotomy: treatment of choice for Zenker's diverticulum.

OBJECTIVE: To evaluate the efficacy and safety of endoscopic stapled diverticulotomy in the treatment of patients with Zenker's diverticulum. STUDY DESIGN: Cohort study. METHODS: Fourteen elderly patients (11 men and 3 women) with Zenker's diverticulum were evaluated in a community hospital setting from July 1996 to November 1999. Before surgery patients had significant dysphagia, regurgitation, cough, or aspiration pneumonia. The common septum between the diverticulum and cervical esophagus was visualized with a Weerda diverticuloscope. While using videoendoscopic monitoring, the septum was divided and the edges simultaneously sealed with a linear endoscopic stapler. Average operative time was 31 minutes. RESULTS: The operation was successfully performed in 11 of 14 patients. In the three unsuccessful cases, one patient's pouch was too small to staple and the other two patients had a septum that was difficult to visualize with the diverticuloscope. There was no significant postoperative morbidity or mortality. Patients started a liquid diet on the first postoperative day and resumed a soft diet a week later. They were usually discharged on the first postoperative day. Most patients reported significant improvement with resolution of dysphagia and regurgitation. CONCLUSIONS: Compared with the traditional open technique, the endoscopic stapled diverticulotomy technique is safe, quick, and effective and requires a shorter length of stay in the hospital. Therefore it has become our treatment of choice for elderly, high-risk patients with a large (>2 cm) hypopharyngeal (Zenker's) diverticulum.

Current trends in management of Zenker diverticulum.

Zenker's diverticulum is a relatively common problem encountered by head and neck surgeons. Careful review of the available literature regarding its pathogenesis indicates that Zenker diverticulum likely occurs as a result of increased intrabolus pressures during swallowing secondary to cricopharyngeal spasm. Rational treatment for Zenker diverticulum therefore addresses cricopharyngeal spasm. The traditional approach to diagnosis and management of Zenker diverticulum has been based on standard techniques and principles. For example, diverticulectomy with concurrent cricopharyngeal myotomy is an acceptable form of treatment with a high success rate. However, recent advances in endoscopic stapling and carbon dioxide laser technologies have added new options to the therapeutic armament of the otolaryngologist. For appropriately selected patients, endoscopic staple-assisted diverticulostomy is a minimally invasive, safe, and effective procedure associated with shorter hospital stays, more rapid postoperative recovery, decreased time to resumption of oral intake, and high levels of patient satisfaction.

Uterine cervical diverticulum resembling a degenerated leiomyoma.

BACKGROUND: Uterine diverticulum is a very rare anomaly. Most previously reported cases were called "pregnancy-associated sacculations," and only 2 cases were considered true uterine diverticula. CASE: A 41-year-old woman presented with fever and lower abdominal pain. An extrauterine mass was detected, and a hysterectomy was performed. Pathological examination revealed a cystic uterine diverticulum lined with cervical glands and myometrium arising from the cervix. The final diagnosis was an infected uterine cervical diverticulum. CONCLUSION: Cervical diverticulum is a rare lesion that should be added to the differential diagnosis of a woman presenting with a pelvic mass.

Carcinoma in a bladder diverticulum: presentation and treatment outcome.

PURPOSE: In this retrospective review we characterize the outcomes of patients treated for transitional cell carcinoma in a bladder diverticulum. MATERIALS AND METHODS: Between 1986 and 2001, 39 patients were treated for tumors in a bladder diverticulum. All patients underwent initial transurethral resection of the tumor. Based on cystoscopic evaluation, bimanual examination and computerized tomography findings, tumors were classified as superficial (Ta, Tis), superficially invasive confined to diverticulum (T1) or extra diverticular (T3+). Patients with superficial or superficially invasive disease were treated either conservatively with repeat transurethral resection, or with partial or radical cystectomy. Patients with extra diverticular extension were treated with partial or radical cystectomy when amenable to surgical extirpation. Predictors of outcome were assessed by univariate and multivariate analyses. End point was overall and disease-specific survival. RESULTS: Of our cohort of 39 patients 13 (33%) presented with superficial disease, 13 (33%) with superficially invasive tumors and 13 (33%) with invasive (extra diverticular) disease. Actuarial 5-year disease specific survival for the cohort was 72 +/- 5.4%. Significant differences in 5-year disease specific survival were observed among patients presenting with superficial tumors (83 +/- 9%), superficially invasive tumors (67 +/- 7%) and extra diverticular disease (45 +/- 14%). Of the patients presenting with T1 tumors the primary mode of treatment did not correlate with outcome. In a multivariate model clinical staging was the only independent predictor of outcome and concomitant carcinoma in situ reached borderline significance. CONCLUSIONS: Our data support a conservative approach for tumors confined to the bladder diverticulum, provided complete removal is feasible and close surveillance ensues.

The endoscopic management of Zenker diverticulum: CO2 laser versus endoscopic stapling.

OBJECTIVE: The purpose of this project was to analyze the endoscopic management of Zenker diverticulum (ZD) using both the CO2 laser and endoscopic stapling techniques. This study compares the two techniques in terms of diverticulum size, onset to oral intake, hospital stay, resolution of symptoms (dysphagia and regurgitation), and complications. STUDY DESIGN: A retrospective consecutive case series was performed at an academic medical center. METHODS: Forty patients underwent an attempted endoscopic resection of the ZD using either the CO2 laser or the endoscopic stapling technique. The two techniques were compared on a variety of parameters, including diverticulum size, hospital stay, onset to oral intake, resolution of symptoms, and complications. Symptom scores were obtained before and after surgery with a patient self-reported scoring report (scale 0-3 for both dysphagia and regurgitation with 0 indicating asymptomatic and 3 severe symptoms). RESULTS: Forty patients underwent an attempted endoscopic management of ZD. Five patients (12.5%) failed endoscopic exposure (four converted to open, one observed). Sixteen patients underwent CO2 laser management and 19 underwent endoscopic stapling. The mean diverticulum size (3.8 cm CO2 laser versus 4.4 cm stapling) was not significantly different for the two groups. Both groups demonstrated a significant decrease in preoperative versus postoperative dysphagia and regurgitation symptoms scores, respectively, CO2 laser dysphagia scores decreasing from 2.75 to 1.38 and the regurgitation score dropping from 1.51 to 0.68, whereas endoscopic stapling dysphagia score decreased from 2.74 to 1.21 and the regurgitation score dropped from 1.37 to 0.53. Overall, 86% of patients demonstrated an onset of liquid intake on postoperative day 1 and the average length of stay was 3.4 days in the CO2 laser group and 1.5 days in the endoscopic stapling (P < .0015). Complications included dental trauma in four patients (two CO2 laser and two stapling) and subcutaneous air in three patients (all three CO2 laser). There were no cases of mediastinitis, recurrent laryngeal nerve injury, fistula, or perioperative death. CONCLUSIONS: The endoscopic management of ZD is a safe and effective technique. The endoscopic stapling technique appears to have an improved efficacy and safety when compared with the CO2 laser technique. The two techniques are compared and contrasted.

Meckel diverticulum: ten-year experience in adults.

OBJECTIVES: Meckel diverticulum, a congenital gastrointestinal anomaly, is well studied in pediatrics, but less so in the adult population. At the Charleston Area Medical Center (CAMC), in addition to the removal of Meckel diverticula in symptomatic patients, diverticula are commonly removed when found incidentally during other procedures. We present our experience over the past ten years with this condition, unusual in the adult population. METHODS: From 1992 to 2002 at the Charleston Area Medical Center, Meckel diverticula were removed from 47 patients older than 18 years of age. We reviewed the age, sex, indication for removal, pathologic findings, and perioperative complications of these cases. RESULTS: Diverticula were removed most often from female patients (31 female, 66%; 16 male, 34%). The removal of the diverticulum was incidental in 35 patients (74.5%) and symptomatic in 12 (25.5% percent). Symptomatic patients presented with: obstruction (n = 4), acute bleeding (n = 1) and diverticulitis (n = 7). Female patients were significantly less likely than male patients to be symptomatic (4 of 31, 13% among females, and 8 of 16, 50% among males; P < 0.05). Heterotopic mucosa was identified in six patients, two of whom were symptomatic at the time of removal. Gastric mucosa was found in all six of the diverticula with ectopic mucosa, although one of the six had a mixed gastric and pancreatic cell population. One asymptomatic patient had a malignancy identified as a 1.5 cm carcinoid with no evidence of metastatic disease. An adenomyoma was found incidentally in one patient upon pathologic evaluation. Hospital complications that could possibly be attributed to removal of diverticula included two wound infections and two anastomotic leaks requiring exploration (8.5% morbidity). Complications were experienced by two asymptomatic females, one asymptomatic male, and a symptomatic male. There were no mortalities. CONCLUSIONS: Meckel diverticulum is found infrequently in the adult population. Adults rarely become symptomatic, but symptoms that do arise are associated with significant morbidity. Complications directly attributable to diverticulum removal are uncommon; however, those that do occur are often life threatening. Therefore, incidental removal of asymptomatic diverticula, particularly in women, is not recommended.

Ureteric replacement with Meckel's diverticulum.

OBJECTIVE: To report on four patients with obstruction of the upper urinary tract due to severe ureteric strictures at different levels, in whom a Meckel's diverticulum was used for ureteric replacement. PATIENTS AND METHODS: The patients were aged 3-64 years at the time of operation. In every patient, a Meckel's diverticulum was used to bridge a ureteric defect after recurrent reconstructive procedures. RESULTS: The mean (range) follow-up was 36 (12-69) months. There were no surgical complications, apart from mucus production in one case and renal function was normal in all patients after surgery. In one case, the invaginated Meckel's diverticulum was used for reflux protection. CONCLUSIONS: A Meckel's diverticulum, if present, appears to be an ideal intestinal substitute for a ureteric defect. The advantages of its use are its unique blood supply, its mobility, and its minimization of functional bowel length resection.
