Appendicolith. Significance in acute appendicitis and demonstration by computed tomography.

A case of periappendical abscess is presented in which the diagnosis was made by demonstration of an appendicolith in a large abscess cavity by computed tomography (CT) in conjunction with the clinical signs and symptoms. However, the appendicolith was not detected by plain film radiography. We stress that CT is more sensitive in detection of such small calcified bodies than plain film radiography and that the true incidence of appendicolith in acute appendicitis could be higher than that reported previously.

Idiopathic cecal ulcer. Diagnosis by colonoscopy followed by nonoperative management.

Idiopathic ulcer of the cecum has been considered a rare condition requiring surgical treatment because of a high incidence of complications, including bowel perforation. Cecal ulcerations are usually diagnosed at the time of surgery for presumed appendicitis or peritonitis of unknown origin. Preoperative diagnosis of cecal ulcer by barium enema has been unreliable and previous literature cites only one case diagnosed by colonoscopy. We describe four cases in which the diagnosis was made at colonoscopy. Three of our four patients were treated conservatively and did not require laparotomy. Idiopathic cecal ulcer should be considered in the differential diagnosis of lower gastrointestinal hemorrhage as well as atypical appendicitis. If the diagnosis of cecal ulcer is made by colonoscopy in a patient without evidence of an acute abdomen, conservative management may be followed by complete healing, avoiding unnecessary surgery.

Generalized amyloidosis from beta 2-microglobulin, with caecal perforation after long-term haemodialysis.

A 73-year-old man with chronic renal failure of undetermined aetiology had received haemodialysis for 12 years when he died of acute purulent peritonitis due to caecal perforation. Amyloid deposits detected in a cystic bone lesion in the left hip had caused a pathological fracture 17 days before death. At autopsy, extensive amyloid deposits were found in the osteoarticular system, in the cartilaginous surface and the capsular tissue of joints, ligaments, vertebral discs and bone. In addition, vascular amyloid deposits were diagnosed in the heart, kidneys, testes, lungs, skin and in the gastrointestinal tract. A special feature of this case were interstitial amyloid deposits forming a fine-meshed structure in the myocardium and plate-like deposits in the gastrointestinal tract. Immunohistochemically, all these deposits reacted strongly with antibody to human beta 2-microglobulin but showed no reaction with antibodies to AA, A-lambda, A-kappa and AF. The present case demonstrates that extra-osteoarticular manifestations of AB-amyloidosis can cause serious complications.

Cecal diverticulitis: a continuing diagnostic dilemma.

Cecal diverticulitis is a rare entity and remains a difficult diagnostic problem. A retrospective review was undertaken of 16 patients (11 men, 5 women; average age, 33.2 years) with a pathologic diagnosis of cecal or right colon diverticulosis who received treatment from 1979 to the present. Preoperative symptoms were difficult to distinguish from appendicitis. The majority complained of right lower quadrant pain and tenderness. Diagnostic studies were not helpful. Preoperative diagnosis was appendicitis in 88% (14 of 16) and correct in 1 patient (6%). At exploratory celiotomy, the surgeon was able to make the diagnosis of cecal diverticulitis in 9 (60%) of the 15 patients in whom the correct diagnosis had not been made preoperatively. Neoplasm was suspected in 5 patients, and an appendiceal abscess was suspected in 1. Treatment was colectomy in 9 and local excision in 4 patients. In 3 patients, the inflamed diverticulum was left in situ at initial exploration; all underwent later excision, one of these urgently for sepsis. No patient died; however, one anastomotic leak requiring reoperation occurred. On the basis of this experience, we recommend excisional therapy in all cases in which the intraoperative diagnosis is certain. Suspicion of a neoplastic process continues to prompt colectomy in an emergency setting.

Sonography of appendiceal intussusception.

A case in which appendiceal intussusception was diagnosed preoperatively by sonography is described. The sonographic finding of multiple concentric hypoechoic and hyperechoic rings was confirmed at laparotomy to be due to appendiceal intussusception. Demonstration of the sonographic coiled spring sign in the right lower quadrant should raise the possibility of appendiceal intussusception. The differential diagnosis is discussed.

Gas-filled appendix with meniscus: outline of the appendicolith.

A meniscus was produced in a gas-filled appendix by the outline of the obstructing appendicolith. This meniscus appearance should be specific for appendicitis since it represents the obstructing stone. This sign can be elicited by oblique or other projections, perhaps with fluoroscopic control.

CT diagnosis of cecal herniation through the foramen of Winslow.

The computed tomographic (CT) appearance of a case of cecal herniation through the foramen of Winslow is described. This is an extremely uncommon type of internal hernia, and, to the best of our knowledge, its CT appearance has not been reported. Its recognition is important to both establish a preoperative diagnosis and to distinguish it from a lesser sac collection or abscess.

Intestinal tuberculosis: findings on double-contrast barium enema.

Seven cases of intestinal tuberculosis in an active stage were studied by the double-contrast barium enema (DCBE) method. Formerly, diagnosis of intestinal tuberculosis in the early stage by single-contrast barium enema (SCBE) and barium meals was based on functional phenomena, such as spasm and hypermotility of the ileocecal region. Presently, this can be better accomplished by DCBE. DCBE enables the detection of shallow ulcers with their characteristic elevated margins. These ulcers are frequently slim and transversally oriented. Confluence of ulcers may create whole girdle ulcers or affect entire segments. In more advanced stages, characteristic deformities, also evident by SCBE, such as symmetrical annular stenoses, shortening, retraction, pouch formation, and the frequently observed pathology of the ileocecal valve and the cecal region, acquire a new dimension with DCBE.

Cecal hernia into the lesser sac.

Two cases of cecal herniation through the foramen of Winslow into the lesser sac are presented. This unusual and potentially life-threatening form of internal herniation can be diagnosed radiographically on plain abdominal radiographs and barium studies by identifying the cecum lying posterior and medial to the stomach in association with the absence of the cecum in the right lower quadrant of the abdomen. One of the described cases is unique in that the patient was asymptomatic relative to the internal hernia. The other case clearly demonstrates the importance of increased intra-abdominal pressure as a causative factor in foramen of Winslow hernia.

Reduction of cecal volvulus by multiple barium enemas.

It has been frequently stated that barium enema has no value in the treatment of cecal volvulus. We present a patient with cecal volvulus who was effectively treated by barium enema; however, multiple studies were required to achieve optimal results. In a subset of patients with cecal volvulus, laparotomy may be avoided by the use of barium enema.

Midgut malrotation, the reliability of sonographic diagnosis.

We are unaware of any other anatomical study which deals with normal variations in the relationship between the superior mesenteric artery (SMA) and the superior mesenteric vein (SMV). In our investigation in the majority of cases, the SMV lies to the right of the SMA. It has been suggested that ultrasonographic demonstration of a left sided SMV, is characteristic of midgut malrotation so a prospective study was undertaken in order to try to correlate the position of the mesenteric vessels on Ultrasound with the radiological diagnosis of midgut malrotation on upper GI series. 427 children (95% infants) who were planned for upper GI investigation, have had color Doppler U.S. of the mesenteric vessels before the barium study. In 67 cases, the mesenteric vessels were obscured by intestinal gas. Among them, there were 2 cases of malrotation. Three different positions of the mesenteric vessels were found in the 360 remaining cases. 1) A left sided SMV was found in 4% of the cases, all had midgut malrotation on X-rays and at surgery. 2) A mesenteric vein anterior to the SMA was found in 5% of the cases, 28% had midgut malrotation. 3) A normal right sided SMV was found in 91% of the cases. However 3% of these had midgut malrotation. There are anatomical variations in the position of the mesenteric vessels and a normal relationship between SMA and SMV does not exclude the possibility of intestinal malrotation. Nevertheless, ultrasound remains a useful noninvasive screening technique for the diagnosis of midgut malrotation.
