[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.

Differentiating sigmoid diverticulitis from carcinoma on CT scans: mesenteric inflammation suggests diverticulitis.

OBJECTIVE: The purpose of this study was to analyze the usefulness of two specific CT signs of sigmoid mesenteric inflammation (fluid at the root of the mesentery and vascular engorgement) for identifying and differentiating sigmoid diverticulitis from carcinoma. MATERIALS AND METHODS: CT scans of 69 patients with surgically proved sigmoid diverticulitis were retrospectively reviewed and compared with CT findings in 29 patients with surgically proved sigmoid carcinoma. Two specific patterns of inflammation of the sigmoid mesentery were analyzed: fluid at the root of the sigmoid mesentery and engorgement of the sigmoid mesenteric vessels. RESULTS: The CT findings were present more often in patients with sigmoid diverticulitis than in those with carcinoma (p < .001). Fluid at the base of the mesentery had a sensitivity, specificity, and positive predictive value for diverticulitis of 36%, 90%, and 89% respectively. Vascular engorgement alone had a sensitivity, specificity, and positive predictive value of 29%, 100%, and 100%, respectively. CONCLUSION: Our results suggest that CT findings of fluid at the root of the mesentery and vascular engorgement are useful in distinguishing sigmoid diverticulitis from carcinoma of the sigmoid.

[Colonic diverticulitis: diverticulitis with complications and its treatment (author's transl)].

Complications (stenosis, intestinal obstruction, abscess or fistula formation, inflammation, etc.) of colonic diverticulitis are seen in 35% of patients affected. Multiple operative procedures involve less risk than surgery performed in a single session. The mortality in emergency surgery is reported to be up to 40%, while subsequent resection of the diseased colon involves the usual mortality of surgery on the colon, i.e. 1.5-9%. The vital factor in this illness is the earliest possible surgical treatment of the diseased diverticulum, so that the extremely problematical complications can be avoided.

[Surgical therapy of inflammatory bowel diseases: ulcerative colitis--diverticulitis. Surgical choices in diverticulitis--conventional or laparoscopic surgery?].

There are no prospective randomized studies available to decide which surgical approach should be superior to treat sigmoid diverticulosis. Analysis of clinical studies evaluating laparoscopic or conventional surgery are presenting results as follows: for elective surgery morbidity ranges between 12-20% and mortality rates between 0-2% indicating comparable complication rates. For emergency operations only data from open surgery are available, with morbidity of 33-57% and mortality rates of 7-16%. Advantages of conventional approach are availability, reliability of the surgical technique and there is no patient selection required. Laparoscopic access may offer superior patients comfort and reduce cost, length of hospital stay and resocialisation. It remains to be proven, which approach may be the option of choice in the future, while this surgical technique is still developing.

[Surgical therapy in right-sided diverticulitis].

INTRODUCTION: Left-sided diverticulitis is a common disease in Western countries, whereas right-sided diverticultitis is rare and symptoms are often similar to the clinical signs of an acute appendicitis. It was the aim of this study to analyse surgical experience in right-sided diverticulitis. METHODS: All patients who underwent resectional surgery for both right-sided and sigmoid diverticular disease were entered prospectively in a registry database (8-year observation period, 1996-2003). For the current study, a retrospective analysis of all patients who underwent ileocolic resection or right colectomy for right-sided colonic diverticulitis was performed, specifically focussing on incidence, clinical symptoms, indication for surgery, type of procedure, and histopathological parameters including immunohistochemistry, and outcome in right-sided diverticulitis. RESULTS: Within eight years, 481 patients were treated surgically for chronically recurrent or acute complicated diverticular disease: 468 patients with sigmoid diverticulitis, 12 patients with right-sided diverticulitis, and 1 patient with combined right-sided and sigmoid diverticular disease. This corresponds to an incidence of right-sided diverticulitis of 2.5 % related to the total number of resections for diverticulitis, and an incidence of 1.3 % in relation to the appendectomies in our patients. In 4 patients, acute appendicitis was presumed preoperatively. Most common diagnostic tool was ultrasonography. Right colectomy was performed in 9 patients with complicated cecal diverticulitis, whereas ileocolic resection was performed in 2 patients and simultaneous ileocolic and sigmoid resection was carried out in one patient. Postoperatively, no morbidity occurred. Histopathological assessment showed local perforation in 75 % (9/12). Hypoganglionosis or aganglionosis was detected in 5 of 12 resected specimen. DISCUSSION: As right-sided diverticulitis is a rare colonic disease in Western countries, the differentiation from acute appendicitis can be difficult. In general, there is no difference in the treatment of right-sided diverticulitis compared to left-sided diverticulitis, and surgery is only indicated in complicated right-sided diverticulitis. Resection of the inflamed colon with primary anastomosis is safe and can be performed by laparoscopy in experienced centers. At present, it can only be speculated whether hypoganglionosis or aganglionosis are causative factors in the etiology of right-sided diverticulitis.

Diverticulitis: a progressive disease? Do multiple recurrences predict less favorable outcomes?

INTRODUCTION: Our understanding of complicated diverticulitis is based on outdated literature. Antecedent episodes of diverticulitis are felt to increase the risk of developing complicated diverticulitis, as well as its subsequent morbidity and mortality. Practice parameters recommend elective resection after 2 episodes of diverticulitis to reduce this morbidity and mortality. METHODS: A total of 150 patients with prior episodes of diverticulitis who were hospitalized with complicated diverticulitis were retrospectively analyzed. Statistical analysis was conducted using chi and Fisher exact test tests. RESULTS: Patients were separated into 2 groups for analysis: group A = those with 1 or 2 prior diverticulitis episodes (n = 118) versus group B = patients with more than 2 prior episodes (n = 32). Characteristics of the groups were similar for age and preexistent comorbid conditions. The majority of patients presented with pericolonic abscess and inflammatory phlegmon. Perforated diverticulitis occurred more often in group A compared with patients with >2 episodes of diverticulitis. Because of the higher rate of perforation, patients in group A underwent surgical diversion more often than group B patients. No significant differences in operative complications, morbidity, or mortality rates were identified between the groups. CONCLUSION: Patients with multiple (>2) episodes of diverticulitis are not at increased risk for poor outcomes if they develop complicated diverticulitis. Morbidity and mortality rates are not significantly different between patients with multiple episodes of diverticulitis compared with those with 1 or 2 prior attacks. Reevaluation of the practice of elective resection as a strategy for reducing the mortality and morbidity from complicated diverticulitis is needed.

Surgery for right-sided colonic diverticulitis: results of a 10-year-observation period.

INTRODUCTION: In contrast to sigmoid diverticular disease, right colonic diverticulitis is a rare disease in Western countries. The clinical presentation is often similar to acute appendicitis. OBJECTIVE: The aim of this study was to analyze surgical challenge in right-sided diverticulitis. MATERIALS AND METHODS: All patients who underwent resection for both right-sided and sigmoid diverticular disease were registered prospectively in a database (observation period, 1996-2005). A retrospective analysis of all patients who underwent resection for right-sided colonic diverticulitis (ileocolic resection, right colectomy) was performed. Special focus was set on incidence, clinical symptoms, indication, procedure, clinical outcome, and histopathologic findings including immunohistochemistry. RESULTS: From a total of 593 patients treated surgically for recurring or acute complicated diverticular disease, the majority (97.8%) suffered from sigmoid diverticulitis (n = 580), whereas 2.2% (n = 16) underwent surgery for right-sided diverticulitis (including three patients with combined sigmoid and cecal diverticulitis). Related to the total number of appendectomies (n = 1167), this represented an incidence of 1.4%. In five of 16 patients, acute appendicitis was presumed preoperatively. Most common diagnostic was ultrasonography. In the group of patients with right-sided diverticulitis, the most common procedure was right hemicolectomy (n = 10), followed by ileocolic resection (n = 3) and combined right colonic resection with sigmoid resection (n = 3). Histopathological investigation confirmed complicated diverticulitis of the cecum with local perforation or abscess in 75% of the patients (12/16). Hypoganglionosis or aganglionosis was diagnosed in seven of the 16 resected specimens. DISCUSSION: As right-sided diverticulitis is a rare colonic disease in Western countries, the differentiation from acute appendicitis may be difficult. In general, there is no difference in the treatment of right-sided diverticulitis compared to left-sided diverticulitis. As most cases will remain clinically unimminent, surgery is only indicated in complicated right-sided cases. Resection of the inflamed colonic segment with primary anastomosis is safe and can be performed laparoscopically. It can only be speculated whether hypoganglionosis or aganglionosis is a causative factor in the etiology of right-sided diverticulitis.

[Clinical characteristics of colonic diverticulitis in Koreans].

BACKGROUND/AIMS: In western countries, symptomatic diverticulitis develops in about 20% of the population with colonic diverticula, and it is mainly located at the left-sided colon. The clinical characteristics of diverticulitis have rarely been investigated although its incidence is increasing in Asia including Korea. The aim of this study was to compare diverticulitis with asymptomatic diverticulosis and to compare the clinical characteristics of right-sided diverticulitis with those of left-sided diverticulitis. METHODS: We retrospectively investigated the medical records of the patients who had symptoms and signs of diverticulitis. Their diagnosis was confirmed with computed tomography, barium study, colonoscopy and/or operations at Samsung Medical Center from September 1998 to February 2002. The control cases of asymptomatic and incidental diverticulosis were randomly selected during routine health check-up after matching age and sex. RESULTS: Twenty-seven patients with diverticulitis (male : female = 14 : 13) were included. The mean age was 53 (27~86). The ratio of right and left diverticulitis was 20:7, which was similar to the ratio of diverticulosis. The complications, especially perforation, were more frequent in the patients with left-sided diverticulitis (p<0.05). CONCLUSIONS: Colonic diverticulitis is more prevalent at the right colon and left colonic diverticulitis has more complications than right colonic diverticulitis in Korea.

Colonic diverticulitis: impact of imaging on surgical management -- a prospective study of 542 patients.

The aim of this study was to compare the performance of the CT and the water-soluble contrast enema (CE) in the diagnosis and the severity of acute left-colonic diverticulitis, and to recognize the impact of CT during the acute phase and after a first acute episode successfully treated medically. From 1986 to 1997, all patients admitted in our emergency center with clinically suspected left-colonic diverticulitis had a CE and a CT within 72 h of their admission, unless clinical findings required immediate laparotomy. They were prospectively included in the study if one or both radiological exams showed signs of acute diverticulitis and/or diverticulitis was surgically removed and histologically proven. Diverticulitis was considered moderate when CT showed localized thickening of the colonic wall (5 mm or more) and inflammation of pericolic fat and CE showed segmental lumen narrowing and tethered mucosa; it was considered severe when abscess and/or extraluminal air and/or contrast were observed on CT and when one or both of the latter signs were seen on CE. Five hundred forty-two patients entered the study; 465 patients (86%) had a CT exam, 439 (81%) had a CE, and 420 (77%) had both exams. The performance of CT is significantly superior to CE in terms of sensitivity (98 vs 92%, p<0.01), and in the evaluation of the severity of the inflammation (26 vs 9%, p<0.02). Moreover, of 69 patients who had an associated abscess seen on CT, only 20 (29%) had indirect signs of this complication on CE. During the acute phase the chances of medical treatment failure are statistically greater when diverticulitis is considered severe on CT than when it is considered moderate (26% for the severe diverticulitis vs 4% for the moderate ones, p<0.0001). After successful medical treatment of the acute episode, patients with severe diverticulitis on the CT had statistically greater incidence of secondary bad outcome than patients with moderate diverticulitis (36 vs 17%, p<0.0001). Computed tomography should be preferred to CE as the initial radiological exam of diverticulitis because of its statistically significant superiority in sensitivity and for its statistically much higher performance in the detection of severe infection, especially when an abscess is associated with the disease. The severity of diverticulitis on CT is statistically predictive of the risk of medical treatment failure during the acute phase and of the chances of bad secondary outcome after a successful medical treatment of the first episode.
