The utility of computed tomography in colonic diverticulitis.
Forty-one patients admitted to our hospital during an 18-month period with the clinical diagnosis of colonic diverticulitis were analyzed to evaluate the utility of computed tomography (CT). Abdominal pain and leukocytosis were the most common presenting manifestations, 75 and 66%, respectively. Just over one-half of the patients also demonstrated hematuria. Twenty patients required surgical intervention, most commonly for failure to improve despite medical management. Preoperative studies included 10 sigmoidoscopies, 30 plain abdominal roentgenograms, 20 barium enemas (BE), and 24 CT scans. Two CT scans were also obtained after operation for successful percutaneous drainage of intra-abdominal abscesses. Abdominal roentgenograms were most commonly obtained but least helpful, with only one third demonstrating any abnormality whatsoever. Sigmoidoscopy was least commonly performed but almost universally abnormal. Specificity was low, however, in that spasm with inability to advance the endoscope was the most common finding. Of the 20 barium enemas obtained, 60% had findings consistent with diverticulitis, most commonly localized perforation or fixed narrow segment. Sixty-three per cent of CT scans were abnormal. The most frequent findings were localized thickening of the colonic wall and increased density in the pericolic fat. Diverticular abscess, which may be inferred by other studies, was definitely diagnosed in one third of the patients with abnormal CT scans. CT also provided the ability to identify extracolonic intra-abdominal pathology. The study demonstrates that both barium enema and CT are effective in diagnosing diverticulitis, although CT can be performed without risk. CT played no therapeutic role before operation, although two patients benefited after operation by CT-guided drainage of intra-abdominal abscesses. The decision for surgery was most frequently dependent on clinical examination and never solely on the basis of either the barium enema or CT in this study. The major benefit of CT appears to be its ability to identify both gross and subtle changes indicative of diverticular disease and extracolonic pathology in a relatively noninvasive manner.

Incidence, outcome, and proposed management of isolated abscesses complicating acute left-sided colonic diverticulitis. A prospective study of 140 patients.
In a prospective evaluation of 140 consecutive patients with acute left-sided colonic diverticulitis demonstrated by computerized tomography (CT) in all cases, 22 (16 percent) were found to have an associated abscess without peritonitis. Thirteen of these 22 required surgery (seven during the first stay and six from 2 to 11 months after the acute episode; median, three months). Nine patients were treated conservatively, eight of whom are now totally asymptomatic 24 months after the initial attack (range, 10-47 months). There were 10 mesocolic abscesses (seven treated with antibiotics alone), nine pelvic abscesses (seven requiring surgery), and three intra-abdominal abscesses, all operated upon. These results suggest that mesocolic abscesses can usually be managed conservatively without drainage; should surgery be necessary, en bloc resection with immediate anastomosis can usually be safely performed. Pelvic and intraabdominal abscesses behave more aggressively and usually require a two-stage surgical procedure when initial percutaneous drainage cannot be performed or is felt to be hazardous.

[Acute left-sided colonic diverticulitis: diagnosis and surgical indications after successful conservative therapy of first time acute diverticulitis].
PURPOSE: To compare the performances of computed tomography (CT) and water soluble contrast enema in the diagnosis and evaluation of the severity of acute left colonic diverticulitis, and to propose indications for elective colectomy after a first episode of diverticulitis successfully treated medically. PATIENTS AND METHODS: Prospective non-randomized study (1986-1997) of 542 patients (290 women and 252 men with a median age of 64 years) whose final diagnosis was confirmed either histologically or radiologically. 465 patients (86%) had a CT, 439 (81%) had a water soluble contrast enema, and 420 (77%) had both examinations. Diverticulitis was considered moderate when CT showed localized thickening of colonic wall (> or = 5 mm) and inflammation of pericolic fat and water soluble contrast enema showed segmental lumen narrowing and tattered mucosa; it was considered severe when abscess and/or extraluminal air/or extraluminal contrast were described by CT or the two latter by water soluble contrast enema. RESULTS: 410 patients (76%) were treated medically and 132 were operated during their hospitalization. Sensitivity of CT for diagnosis of diverticulitis was 96%, compared to 87% for water soluble contrast enema (p < 0.0001). Severe diverticulitis was found in 139 patients (30%) by CT and in 45 patients (11%) by water soluble contrast enema (p < 0.0001). Age < or = 50 years, severe diverticulitis in the initial CT and associated pelvic abscess were found to be statistically significant parameters to predict the risk of secondary complications after a first episode of diverticulitis successfully treated medically. CONCLUSIONS: Performances of CT for diagnosis and evaluation of severity of acute diverticulitis are statistically higher than that of water soluble contrast enema. We would recommend elective colectomy in patients 50 years of age or younger with a severe diverticulitis in initial CT, and in all patients with an associated pelvic abscess.

Primary resection with anastomosis vs. Hartmann's procedure in nonelective surgery for acute colonic diverticulitis: a systematic review.
PURPOSE: This study compares primary resection with anastomosis and Hartmann's procedure in an adult population with acute colonic diverticulitis. METHODS: Comparative studies published between 1984 and 2004 of primary resection with anastomosis vs. Hartmann's procedure were included. The primary end point was postoperative mortality. Secondary end points included surgical and medical morbidity, operative time, and length of postoperative hospitalization. Random effects model was used and sensitivity analysis was performed. RESULTS: Fifteen studies, including 963 patients (57 percent primary resection with anastomoses, 43 percent Hartmann's procedures), were analyzed. Overall mortality was significantly reduced with primary resection and anastomosis (4.9 vs. 15.1 percent; odds ratio = 0.41). Subgroup analysis of trials matched for emergency operations showed significantly decreased mortality with primary resection and anastomosis (7.4 vs. 15.6 percent; odds ratio = 0.44). No significant difference in mortality was observed in trials matched for severity of peritonitis Hinchey > 2 (14.1 vs. 14.4 percent; odds ratio = 0.85). Sensitivity analysis did not reveal significant heterogeneity between the studies for the primary outcome. CONCLUSIONS: Patients selected for primary resection and anastomosis have a lower mortality than those treated by Hartmann's procedure in the emergency setting and comparable mortality under conditions of generalized peritonitis (Hinchey > 2). The retrospective nature of the included studies allows for a considerable degree of selection bias that limits robust and clinically sound conclusions. This analysis highlights the need for high-quality randomized trials comparing the two techniques.

Suspected acute colon diverticulitis: imaging with low-dose unenhanced multi-detector row CT.
PURPOSE: To prospectively compare the sensitivity and specificity of unenhanced low-dose multi-detector row computed tomography (CT) with those of contrast material-enhanced standard-dose multi-detector row CT in patients suspected of having acute diverticulitis. MATERIALS AND METHODS: Institutional review board approval and informed consent were obtained. One hundred ten consecutive patients (40 men, 70 women; age range, 30-82 years; mean, 57 years) suspected of having acute diverticulitis underwent unenhanced multi-detector row CT with 4 x 2.5-mm collimation, 120 kVp, and 30 effective mAs, as well as contrast-enhanced standard-dose multi-detector row CT with the same parameters but with 120 mAs. All scans were independently read by four readers. Intra- and interobserver agreements were calculated with the kappa statistic. Contrast-enhanced standard-dose scans read by three other experts and considered together with results from colonoscopy, surgery, and pathologic evaluation were used as reference. Differences in sensitivity and specificity between readers, radiation doses, and reading sessions were investigated. Pearson exact test and logistic regression models were used. RESULTS: Colon diverticulitis was present in 39 patients (34%) and was graded as mild in 22 patients (56%) and severe in 17 (44%). Agreement within and between readers was good to excellent. No significant difference was observed in sensitivity (P ranging from .081 to >.99) or in specificity (P ranging from .326 to >.99) for any sign or overall diagnosis between radiation doses by all readers, except wall thickening, which for one reader had a higher specificity at low dose than at standard dose (P = .025). No significant difference in misclassification was detected between doses, regardless of the reader (P ranging from .481 to >.99). At both doses, the most predictive sign for acute diverticulitis was retroperitoneal fat stranding (P < .001). CONCLUSION: Low-dose unenhanced multi-detector row CT has a diagnostic performance similar to that of contrast-enhanced standard-dose multi-detector row CT in patients suspected of having acute diverticulitis.

[Diagnosis of acute colonic diverticulitis: comparison with echography and tomodensitometry].
The sensitivity of ultrasonography (US) as the initial imaging procedure in acute diverticulitis of the left colon was retrospectively compared with that of computed tomography (CT) in 34 patients. Final diagnosis was based on clinical findings and follow-up in a first group of 20 patients with mild diverticulitis, and was proved by surgery in a second group of 14 patients with severe diverticulitis. In the first group, US showed findings consistent with diverticulitis in 19 patients, as did CT. The image of an inflamed diverticulum was shown by US in 10 patients. In the surgical group, findings consistent with diverticulitis were shown by US in 11 cases, and by CT in 13 cases. An inflamed diverticulum was not detected at US in this group of patients, presumably because the diverticulum was incorporated in the inflammatory process. These results suggest that US is a valuable technique in the initial evaluation of patients suspected of having acute diverticulitis, especially when the disease is not severe. The image of an inflamed diverticulum shown at US strongly suggests the diagnosis of mild diverticular disease. When diverticulitis is severe, CT should be performed in addition to US.

Recurrent complicated colon diverticulitis in renal transplanted patient.
Colon perforation due to diverticulitis is a life-threatening complication in the postoperative course of kidney transplantation. In the immunocompromised patient a diagnosis of diverticulitis is difficult to make. We report a 53-year-old woman being kidney transplanted 14 years ago with known diverticulosis. She was admitted with acute severe pain in the lower left abdomen. Abdominal computed tomography (CT) scan indicated a diagnosis of intestinal abscess in the small pelvis. Laparotomy showed a covered sigma perforation with abscess located in the small pelvis (Hinchey-I). Because of the immunocompromised situation of the patient we performed a Hartmann procedure. Her postoperative course was uneventful. In a 6-month interval the intestinal continuity restoration was performed. Twelve days after discharge the patient was readmitted with reduced renal function and increased infection parameters. During physical examination the abdomen was tender. The patient complained of abdominal pain in the left upper abdomen and additional pain in the left shoulder. An antibiotic therapy using ciprofloxacin was already initiated owing to a urinary tract infection. An abdominal CT scan was performed and indicated an intestinal abscess in the left upper abdomen. Laparotomy showed an abscess involving transverse colon, distal jejunum, and proximal ileum (Hinchey-II). Segmental resection of the left colonic flexure, proximal jejunum, and ileum was performed. The postoperative course was uneventful and the patient was discharged on the 8th postoperative day. The present casuistry emphasizes that the immunocompromised patient can undergo diverticulitis twice, and that primary anastomosis is a feasible option for patients with localized peritonitis due to complicated diverticulitis.

Colovesical fistula due to sigmoid colon diverticulitis: a case report.
We present a case of colovesical fistula due to sigmoid colon diverticulitis. A 63-year-old woman was referred to our department with the complaints of dysuria, turbid and foul smelling urine. She was treated twice for acute cystitis at the referral hospitals. A diagnosis of colovesical fistula was confirmed on barium enema. She underwent partial resection of sigmoid colon with primary anastomosis and partial cystectomy with repair of bladder wall and covered with omentum. Retrograde cytography taken on the 20th post-operative day revealed no leakage of contrast medium. She was asymptomatic at 3 months of follow-up.

Transverse colon diverticulitis simulating inguinal hernia strangulation: a first report.
BACKGROUND: Strangulation is the most serious complication of inguinal hernia. Diverticulitis, a common condition, is usually localized in the left colon. The association of complicated inguinal hernia and diverticulitis is rare. METHODS: We report the case of a 73-year-old male patient who presented with a suspicion of strangulated inguinal hernia. RESULTS: CT and operative findings showed transverse colon diverticulitis lodged in an incarcerated inguinal hernia without signs of strangulation. Surgical hernia repair was undertaken while the treatment of diverticulitis was conservative. Follow-up was uneventful. CONCLUSION: This is a first report of documented transverse colon diverticulitis simulating inguinal hernia strangulation.

[Intestinal perforation caused by chicken bone mimicking perforated colonic diverticulitis].
Intestinal Perforation can occur in less than 1% of cases of ingestion of foreign bodies. Clinical suspicion is very important to make the diagnosis since many medical conditions can simulate this pathology. We present a case of a 63 years old man who swallowed a chicken bone that perforated the sigmoid colon and produced a clinical picture mimicking a perforated colonic diverticulitis. At surgery, the bone was removed without any evidence of abscess formation. A Hartmann procedure was performed and we reanastomosed it 3 month later. The patient followed an uneventful postoperative course. We demonstrated that early detection and opportune surgical treatment decrease the risk of developing complications such as abscess formation, intestinal fistula or obstruction.

Acute colon diverticulitis in multiple myeloma patient: an unusual presentation of a colonic perforation. Case report.
This case report describes an acute colonic diverticular perforation occurred to a multiple myeloma patient, taking corticosteroid and morphine therapy, revealed by a subcutaneous emphysema of upper chest and right abdomen as initial presentation. Sigmoid diverticulitis with perforation and generalized peritonitis is a severe complication of the diverticular disease and it is due to diverticular microperforation. This condition occurs more frequently in patients with widespread diverticolosis and usually after 50 years of age, and the frequency of related complications increases with age (and with the use of corticosteroids). Extraperitoneal air from the sigmoid-rectum perforation can escape diffusing superiorly though paravertebral retroperitoneal tissues and via the diaphragmatic iatus into the mediastinum, producing pneumomediastinum and it diffuses to yield superior thoracic emphysema. This report suggests that the diagnosis of retroperitoneal perforation is usually difficult because of the lack of signs of peritoneal irritation and the paucity of symptoms, particularly in patients treated with corticosteroids.

[Developments in the surgical therapy of colonic diverticulitis].
All patients admitted to our department with diverticulitis of the left sided colon between 1980 and 1990 were retrospectively evaluated. Staging was performed according to the Hinchey classification. Altogether, 263 patients were evaluated; 71% had complicated diverticulitis and 29% simple diverticulitis. Of those patients with complicated diverticulitis, 68% required surgery due to abscess formation and/or perforation, 19% because of obstruction, 10% because of fistula formation, and 3% due to intestinal hemorrhage. While primary resection (primary reanastomosis in 82% or Hartmann procedure in 13%) was carried out in 250 patients (95%), 13 patients (5%) did not obtain this result (colostomy) following the initial operation. None of the patients who presented with simple diverticulitis died in the postoperative period. The total operative mortality and mortality for complicated diverticulitis amounted to 6.5% and 9%, respectively. In comparison to a former analysis from our department, resection of the primary focus during the initial operation led to a significant decrease in morbidity and mortality. In patients with complicated diverticulitis and peritonitis, primary resection and anastomosis also achieved favourable results in 78%.

[A case of colo-vesico-vaginal fistula caused by sigmoid colon diverticulitis].
A 74-year-old woman was referred to our hospital with the chief complaints of pneumaturia, fecaluria and discharge of feces and urine from vagina. Fistulography on the vaginal side showed the presence of contrast medium both in the sigmoid colon and bladder. Colonoscopy revealed multiple diverticulosis of the sigmoid colon. Under diagnosis of colo-vesico-vaginal fistula due to sigmoid colon diverticulitis, a one-stage operation removing sigmoid colon, uterus-vaginal wall and urinary bladder wall including the fistula and careful reconstruction was performed. Postoperatively, urinary leakage from vagina in large amounts continued due to the recurrence of vesico-vaginal fistula. An attempt to use human fibrin glue in the recurrent fistula was successful, and the patient was asymptomatic at 21 months of follow-up. Colovesical fistula has been reported in about 10-20% of patients undergoing surgery for complicated diverticulitis, but a combined fistula is a rare condition. Furthermore, we recommend the use of human fibrin glue for a recurrent fistula.
