Urachus is a tubular structure lined between foetal bladder and the umbilicus and is susceptible to complete or partial involution after birth. Persistence of the urachus results in a wide spectrum of anomalies: patent urachus, vesicourachal diverticulum, urachal sinus and cysts are more frequently seen than rare multiple urachal remnants. This kind of pathology focuses the problem of differential diagnosis (tumours, omental and ovarian cysts, vesical diverticulum or duplication) and may be complicated by a superinfection. The Authors discuss a bizarre multiple urachal remnant, presenting with urinary tract symptoms, which may be clinically confused with acute appendicitis or Meckel's diverticulitis. Contribution of sonography for a complete diagnosis is stressed, such as the precise correlation with surgical findings.

An infected urachal cyst classically presents with a tender lower midline abdominal mass and systemic signs of infection, including fever, malaise, and leukocytosis. At times, the findings may be clinically confused with those of acute appendicitis, Meckel's diverticulitis, or peritonitis. Sonography aids in differentiating these entities by identifying the localized cystic mass containing debris, located anteriorly in the low mid-abdomen, extending from the region of the bladder to the umbilicus. We present an unusual case of an infected urachal cyst in a 6-year-old boy who presented with lower abdominal pain, fever, intermittent diarrhea, polyuria and dysuria, a firm, fixed left lower quadrant tender mass, and an elevated white blood cell count.

A study to assess the reliability of clinical symptoms and signs in 50 patients with a presumptive diagnosis of acute appendicitis is presented. The male to female ratio was 3: 2, with age ranging from 2 to 15 years. Abdominal pain was present in 42; tenderness was localized in 35, generalized in 11 and diffuse in 4 patients. Total leucocyte count was above 11,000/cu mm in 31, below 11,000/cu mm in 17 and above 18,000/cu mm in 2. Of the 48 operated patients, 8 had normal appendices and the diagnosis in them was Meckel's diverticulitis 3, ruptured ovarian follicle 2, mesenteric adenitis 2, and salpingo-oophoritis 1. Abdominal pain and right iliac fossa tenderness with contributory investigations are the most reliable indicators of acute appendicitis with a false positive rate of 16.66% only.

The treatment of appendiceal abscess is controversial. For patients initially treated "conservatively" with antibiotics with or without drainage, the role of interval appendectomy is an area of considerable debate. Without interval appendectomy, the true risks of recurrent disease and missed pathological findings are uncertain, and large, long-term, prospective studies are unavailable. To evaluate the role of interval appendectomy, the authors reviewed the histopathologic specimens from patients with presumed appendiceal abscess treated by interval appendectomy. Over a 7-year period, 162 children presented with a clinical diagnosis of perforated appendicitis. Eighteen patients had localized abscesses treated conservatively, followed by interval appendectomy. Standard histopathologic sections of 17 of the 18 appendices were examined by one pathologist who was blinded to the clinical data and to the interpretation of the original pathologist. Of the 11 boys and seven girls (mean age, 7.4 +/- 3.4 years), eight underwent percutaneous drainage and one underwent operative drainage. All received intravenous antibiotics for a mean of 8.6 +/- 3.2 days with a hospital stay of 10.4 +/- 8.3 days. Interval appendectomy was performed at a mean of 92.7 +/- 20.7 days after initial admission, with discharge at a mean of 2 +/- 1.3 days after surgery. There were no complications or deaths. Histopathologic review showed normal appendix (n = 4), normal appendix with mild serositis (n = 6), normal appendix with unsuspected resolved Meckel's diverticulitis (n = 1), appendiceal duplication (n = 1), granulomatous appendicitis (n = 3), and acute appendicitis (n = 2). All appendices had patent lumens, and 15 were documented to be present to the tip. There was no correlation between the histopathologic findings and the interval between abscess and interval appendectomy. Interval appendectomy was performed with no morbidity and a short hospital stay. Two patients had histopathologic recurrent acute appendicitis, five had unsuspected pathological findings (appendiceal duplication, Meckel's diverticulitis, granulomatous inflammation), and none of the appendices had an obliterated lumen, suggesting that all patients were at long-term risk for recurrent disease. These data support the role of interval appendectomy in cases of perforated appendicitis treated conservatively.

Many dangerous surgical complications like intestinal obstruction, acute appendicitis with perforation, ileal perforation in a typhoid patient, Meckel's diverticulitis, disruption of post operative intestinal anastomosis, volvulus, and intussusception are known to occur due to ascariasis, with considerable morbidity and mortality. In this retrospective study of 250 cases of gastrointestinal ascariasis admitted in paediatric surgical wards of Govt. Medical College, Jabalpur (MP), the authors analysed the results of conservative (especially the use of hypertonic saline enema-given just like an ordinary soap water enema but substituting freshly made hypertonic saline in place of soap water) and surgical treatment. The success rate of conservative treatment was 95.6%. Hypertonic saline passes through the incompetent ileo-caecal valve (present in 80% of children) and irritates the worm bolus commonly situated in the terminal ileum, causing it to disintegrate. It also helps to increase the intestinal motility and passage of worms into the colon. The use of hypertonic saline enema is safe and effective in the conservative treatment of gastrointestinal ascariasis. Authors feel that it is the most grossly under utilized part of conservative treatment and deserves to be known and used on wider scale.

Meckel's diverticulitis is a rare disease. In addition to physical examination, abdominal ultrasound can help to pinpoint the diagnosis. By presenting a case report we would like to demonstrate the typical ultrasonographic findings in acute Meckel's diverticulitis and differentiate it from acute appendicitis. A 60-year-old patient was admitted to our hospital with the diagnosis of acute appendicitis. Abdominal ultrasound was performed and a blind ending, liquid-filled segment of small bowel in the right lower quadrant of the abdomen found. This segment was not compressible, no peristalsis was evident, nor was there any anatomical association with the cecum. Locally we found free fluid and hints of inflamed mesenteric fatty tissue. A perforated Meckel's diverticulum was diagnosed and confirmed intraoperatively. The major ultrasonographic difference between an inflamed Meckel's diverticulum and acute appendicitis is its anatomical location. In contrast to the appendix there is no association with the cecum. A diameter of up to 40 mm and a well-defined wall of small bowel with 3 definite layers visible by ultrasound may help to distinguish between a Meckel's diverticulum and the appendix.

This case reports the concomitant findings of carcinoid tumor within a Meckel's diverticulum presenting as an acute abdomen in an adult male. Most Meckel's diverticula remain asymptomatic throughout life, and symptomatic diverticula are virtually nonexistent in older adults. Meckel's diverticulitis is clinically indistinguishable from acute appendicitis, and abnormal or symptomatic diverticula are generally resected. Surgical treatment of Meckel's diverticula is recommended for children during exploration. However, resection is controversial in asymptomatic adults. Carcinoid tumors are the most common primary tumor of the small bowel. The duration of symptoms before diagnosis varies from 2 to 20 years, and half of all patients have incurable abdominal disease at first-look surgery. Metastatic events occur most commonly in the liver with a generally poor prognosis. Surgical resection is the treatment of choice. Both Meckel's diverticula and carcinoid tumor are rare clinical entities, and carcinoid tumors occurring within a Meckel's diverticulum are even more uncommon. Thus, the natural history is difficult to predict and treatment recommendations vary. Solitary, localized, asymptomatic nodules less than 1 cm are generally managed with diverticulectomy or segmental resection. Larger or multiple lesions require wide excision of bowel and mesentery, and hepatic resection may be required for metastatic disease.

Meckel's diverticulum, which is a remnant of the omphalomesenteric or vitelline duct, is the most common congenital abnormality of the gastrointestinal system. Urachal abnormalities, resulting from anomalous urogenital development, are not observed frequently and case reports are mainly represented in literature. The presence of these two congenital anomalies together is a very rare pathology. Complications arising from a Meckel's diverticulum or urachal remnant may clinically mimic acute appendicitis and other surgical pathologies. We report on a patient who underwent surgery for acute appendicitis when it was discovered that the symptoms were produced by a perforated Meckel's diverticulitis. In the course of the surgery, a urachal remnant was found to coexist with the diverticulum.

A man, aged 74, presented with a rare clinical entity of an acute surgical abdomen similar to acute appendicitis. This case showed a non-Meckel's ileal diverticulitis that was complicated with a diverticular perforation and associated peritonitis. This is a very rare but potential life-threatening surgical emergency, mimicking the clinical presentation of acute appendicitis. The subject of small bowel non-Meckel's diverticulitis is reviewed because of the rarity of this condition and the diagnostic challenges it poses.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastro-intestinal tract (approximately 2% of population), and arises from improper closure and absorption of the omphalomesenteric duct. Very few cases of Meckel's diverticulitis on the mesenteric side have been reported in the surgical literature, and no reported cases have been documented on preoperative imaging. We report a 65-year-old woman presenting symptoms and signs of acute abdomen with an initial suspicion of acute appendicitis. MDCT imaging revealed a mesenteric abscess in the right lower quadrant at the level of the distal ileum as a complication of Meckel's diverticulitis on the mesenteric side. The patient recovered after a diverticulectomy without the need for a small bowel resection. This case demonstrates that MDCT is a fast imaging technique that may be helpful in the emergency setting for the preoperative diagnosis of an unusual complicated MD on the mesenteric side.
