Diverticulitis and polycystic kidney disease.

Patients with adult polycystic kidney disease (PKD) have previously been shown to have an increased incidence of complicated diverticulitis after renal transplantation. The purpose of this study was to assess the risk of diverticulitis in the PKD population. We retrospectively reviewed patients with advanced PKD, defined as end-stage renal failure requiring dialysis. Patients were obtained from a single nephrology group practice between January 1985 and January 1997, or from all patients being evaluated or actively considered for renal transplantation at our institution as of May 1997. The incidence and severity of diverticulitis in these patients was compared with that observed in a similar cohort of patients with end-stage renal disease due to other etiologies. The study population consisted of 184 renal failure patients, 59 with PKD and 125 with other causes of end-stage renal disease. Twelve (20%) patients with PKD had a history of active diverticulitis, whereas only 4 (3%) of the non-PKD controls had diverticulitis (P = 0.0003, Fisher's exact test). Six of the 12 PKD patients required surgical intervention. Patients with renal failure due to PKD experience a significantly higher rate of diverticulitis than do other patients with end-stage renal disease. Furthermore, diverticulitis is frequently severe in PKD patients, with 50 per cent requiring surgical intervention. These data suggest that diverticular disease may be an extrarenal manifestation of polycystic kidney disease.

Surgical management of complicated diverticulitis.

The majority of patients with acute diverticulitis can be managed medically. Some will have a complication of diverticulitis such as free perforation with peritonitis, abscess formation, obstruction, or fistula formation. Perhaps even a larger number will develop recurrent diverticulitis, which is associated with an increased rate of complications. Although the preoperative diagnosis of these problems may be obvious in many patients, elderly or steroid-treated patients may have few manifestations of significant intra-abdominal disease. Of extreme importance in the management of these complications of diverticulitis is the preoperative resuscitation. Intravascular volume depletion is replaced with intravenous fluids, and intravenous antibiotics are given. At this time, with any of these complications, it is unusual to perform the classic three-stage operation, which includes an initial diverting colostomy and drainage followed by resection of the involved colon and, finally, a colostomy closure as the third stage. The usual treatment now is a two-stage operation with the initial operation being resection of the diseased segment and formation of a colostomy proximally and either a mucous fistula or a Hartmann's pouch distally. The second stage is the colostomy closure. This two-stage approach is indicated in patients with acute diverticulitis complicated by perforation, whether free or confined with abscess formation, and in patients with obstruction or fistula formation in whom a preoperative bowel preparation is not possible. Resection and primary anastomosis should not be performed in the elderly in the emergency setting for complicated diverticulitis. However, this is the procedure of choice in the elective treatment of diverticulitis and its complications in the elderly.

[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.

[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%.

[Surgical treatment of colonic diverticulitis].

BACKGROUND: Colonic diverticulitis is a serious disease that may require surgical treatment. Early diagnosis and management are necessary to reduce the rates of morbidity-mortality. PURPOSE: This review article was performed in order to discuss the most recent advances in the diagnosis and management of colonic diverticulitis. RESULTS: Patients with acute diverticulitis should be categorized based upon the presence or absence of complications. Patients with complicated diverticulitis should be further categorized into I) pericolonic abscess, II) distant abscess (retroperitoneum or pelvis), III) purulent peritonitis, and IV) fecal peritonitis. In the absence of complications, elective treatment is mainly indicated in patients with recurrent episodes of diverticulitis. In complicated diverticulitis, the surgical alternatives will depend upon the clinical category. The current tendency is to attempt a percutaneous drainage of the abscess, followed by a semi-elective resection. In patients operated upon on emergency basis, resection with a diverting colostomy, with or without anastomosis, is the most widely used procedure. CONCLUSIONS: Surgical treatment for acute diverticulitis should be based upon the presence of complications and their clinical category.

[The value of CT for the diagnosis of acute diverticulitis].

PURPOSE: In acute diverticulitis accurate diagnosis and staging are mandatory to decide on the treatment of the patient. The impact of computed tomography (CT) on the treatment of acute diverticulitis will be discussed. MATERIAL AND METHOD: CT is performed after distension of the distal colon by means of positive,water-soluble contrast media to depict intestinal perforation or penetration. Then intravenous contrast material is administered and spiral scanning is repeated to judge enhancement patterns of the abdominal structures/organs especially of the intestinal wall and to diagnose abscess formation. CT-morphologies of different stages of acute diverticulitis will be described. RESULTS: CT imaging is the only diagnostic method that in case of an acute diverticulitis combines safety with accuracy. On the one hand, it is fast and therefore safe with respect to patient control and on the other hand, it allows accurate staging of the inflammatory process reaching a sensitivity and specificity of up to 100%, each. CT is an appropriate tool to diagnose acute diverticulitis complicated by abscess formation, intestinal penetration or perforation and therefore has direct impact on the treatment of the patient. DISCUSSION: If acute diverticulitis is suspected CT is the method of choice for imaging because of its high impact on the choice of therapy and on the management of complications.

Acute diverticulitis of the cecum and ascending colon diagnosed by computed tomography.

Between June 1984 and August 1985, computed tomography (CT) was performed upon seven patients with diverticulitis of the cecum and ascending colon who presented with acute right lower quadrant symptoms of unknown origin. Three of these patients had undergone an appendectomy, while in the remaining four patients, the history and physical findings were atypical of acute appendicitis. CT findings suggestive of acute diverticulitis including thickening of the intestinal wall and pericolonic inflammation were present in all seven patients. In four patients, the colonic inflammation was limited to the segment of ascending colon superior to the ileocecal valve. In one patient, the inflammation involved both the ascending colon and the cecum, while in the two remaining patients, the inflammatory changes were limited to the cecum. An associated diverticular abscess was present in five patients and all were correctly identified preoperatively by CT. One patient in whom the diagnosis of uncomplicated diverticulitis of the ascending colon was made on the basis of the CT scan, was successfully managed nonoperatively with antibiotics. Five patients required a right hemicolectomy for perforated diverticulitis with abscess. The remaining patient underwent a right hemicolectomy for recurrent episodes of acute diverticulitis. Our experience suggests that CT is useful in the early diagnosis of diverticulitis of the cecum and ascending colon.

Hospitalization for acute diverticulitis does not mandate routine elective colectomy.

BACKGROUND: Previous studies suggest that elective colectomy is often required after an episode of acute diverticulitis. HYPOTHESIS: Acute diverticulitis initially treated nonoperatively does not require elective colectomy. DESIGN: Retrospective cohort study. SETTING: Twelve Kaiser Permanente hospitals in Southern California. PATIENTS: Three thousand one hundred sixty-five patients with acute diverticulitis. INTERVENTIONS: Colectomy or nonoperative treatment with or without percutaneous abscess drainage. MAIN OUTCOME MEASURES: Recurrent diverticulitis. RESULTS: Emergency colectomy was performed in 614 patients (19.4%). Nonoperative treatment was initially used in 2551 patients (80.6%). Of these, 185 patients (7.3%) had an elective colectomy and the remaining 2366 patients (92.7%) did not. Factors associated with undergoing elective colectomy compared with nonoperative treatment were younger age of the patient, fewer comorbidities, and percutaneous abscess drainage. Mean follow-up was 8.9 years, with a maximum of 12 years. After nonoperative treatment, 314 patients (13.3%) recurred-222 patients had a single recurrence and 92 patients had a rerecurrence. After adjusting for other variables, older age (hazard ratio, >/=50 years vs <50 years = 0.68; 95% confidence interval, 0.53-0.87) was associated with a lower recurrence, whereas higher comorbidity was associated with higher recurrence. Gender and percutaneous abscess drainage had no influence on recurrence. All 92 rerecurrences were treated nonoperatively. The risk of a rerecurrence (29.3%) was significantly higher than a first recurrence (P<.001). Age, gender, Charlson comorbidity index, and percutaneous abscess drainage did not predict rerecurrence. CONCLUSIONS: Very few patients with acute diverticulitis treated nonoperatively have recurrence. Younger age was associated with recurrence. A first recurrence was the only factor that predicted rerecurrences. The low recurrence rate argues against routine elective colectomy after successful nonoperative management of acute diverticulitis.

Acute diverticulitis in heart transplant recipients.

Immunosuppressed patients are susceptible to complicated diverticulitis, but reports of this complication are scarce in heart graft recipients. To estimate the prevalence of acute diverticulitis in heart graft recipients, we retrospectively reviewed the cases of diverticulitis in a series of 143 patients who underwent orthotopic heart transplantation in a period of 10 years. Six (4%) of these developed acute diverticulitis and required colectomy. All of them were male patients and were older than 50 years. Four patients underwent urgent laparotomy and colon resection with end colostomy (Hartmann procedure). The two other patients suffered from diverticulitis without generalized peritonitis and underwent laparoscopic sigmoidectomy with direct transanal end-to-end anastomosis. The postoperative outcomes of these six patients were satisfactory. As are other immunosuppressed patients, heart graft recipients are susceptible to diverticulitis. Early surgical management may be safe in well-compensated patients.

[Early resection in diverticulitis (author's transl)].

The danger with diverticulitis is that the disease may progress to life threatening complications. The development of diverticulitis leads from local infiltration and fibrosclerosis to final perforation. Nonresected diverticulitis favors the development of diverticulosis proximal to the affected bowel. Conservative therapy seems to be of little use in avoiding the progression of recurring diverticulitis. Signs of irreversible diverticulitis are repeated attacks, signs of local peritonitis, fixed deformation of the wall and stenosis, revelaed by barium enema. One-stage resection was performed in 101 patients for uncomplicated diverticulitis. There was one death (myocardial infarction).

Sonography in acute colonic diverticulitis. A prospective study.

The clinical value of high-resolution real-time sonography for the diagnosis of acute and complicated colonic diverticulitis was prospectively studied in 130 consecutive patients with abdominal complaints, because of which the disease entered into differential consideration. The results of ultrasound investigation were compared with those of clinical examination on admission. Regarding history and initial clinical evaluation, diverticulitis was graded as "highly suspected" in 19 (36.5 percent) out of a total of 52 patients with later proven colonic diverticulitis (prevalence 40 percent), as "possible but equivocal" in 24 (46.2 percent), and as "very unlikely" in the remaining nine (17.3 percent) patients. Ultrasonography enabled the diagnosis of diverticulitis with an overall accuracy of 97.7 percent, a sensitivity of 98.1 percent, and a specificity of 97.5 percent. The predictive values of positive and negative ultrasound examinations were 96.2 percent and 98.5 percent, respectively. The echomorphologic features of acute diverticulitis include visualization of a colon segment presenting with local tenderness on gradual compression, which showed hypoechogenic thickening of the wall and a targetlike appearance in transverse view due to inflammatory changes and muscular thickening. Sonographic signs of peridiverticulitis (hyperechoic halo) were found in 96 percent of patients, echogenic diverticula in 86 percent. Twelve (92 percent) of 13 abdominal abscesses were detected on initial ultrasound examination and could be treated by percutaneous drainage in seven cases, while six required surgical intervention. These results indicate that high-resolution sonography with graded compression is highly sensitive and specific for the imaging diagnoses of acute colonic diverticulitis and complicating abscess.

Management of right colon diverticulitis: a 10-year experience.

BACKGROUND: Controversies abound as regards the optimal treatment for patients with diverticulitis of the right colon. METHODS: This is a retrospective review of 113 patients with a diagnosis of right colonic diverticulitis who received treatment at the China Medical University Hospital from July 1994 to June 2004. RESULTS: Medical therapy was undertaken in 56 patients diagnosed preoperatively with uncomplicated diverticulitis. All but one patient was successfully treated with bowel rest and antibiotics. Of the 51 patients with a preoperative diagnosis of acute appendicitis, 32 received appendectomy along with postoperative antibiotic therapy, 8 received diverticulectomy in addition to appendectomy, and 11 received colectomy. In all, 17 patients required right hemicolectomy or ileocecal resection due to diverticulitis-related complications or suspected malignancy. Of the 87 (56-1+32) patients who responded to conservative treatment, 11 developed recurrent diverticulitis. All 11 patients were successfully treated with medical therapy, and 2 subsequently received elective right hemicolectomy. Of the 9 patients who received medical treatment alone at the second attack, 2 suffered a third attack. Both were successfully managed with medical therapy. CONCLUSIONS: For uncomplicated diverticulitis of the right colon diagnosed preoperatively, antibiotic therapy with bowel rest is an effective treatment. Once it is encountered during surgery for presumed acute appendicitis, a conservative approach involving prophylactic appendectomy and postoperative antibiotics is recommended. For patients with recurrent diseases, medical treatment is still safe and efficient. Colectomy is indicated when complications occur or when malignancy is strongly suspected.

Multi-slice spiral CT in routine diagnosis of suspected acute left-sided colonic diverticulitis: a prospective study of 120 patients.

This prospective study evaluated the use of multi-slice CT (MSCT) for detection of clinically suspected left-sided colonic diverticulitis with regard to diagnosis, complications and alternative diagnoses. One hundred twenty patients with clinically suspected acute left-colonic diverticulitis underwent MSCT of the lower abdomen with IV contrast after rectal application of iodic contrast. The MSCT results were compared with histopathological and intraoperative findings or other radiological or endoscopic methods and clinical outcome. Acute diverticulitis was proven in 67 of the 120 (55.8%) patients, which was detected by MSCT with an accuracy of 98% (sensitivity 97%, specificity 98%). Contained perforation or abscess formation were detected with an accuracy of 96% (sensitivity 100%, specificity 91%) and 98% (sensitivity 100%, specificity 97%), respectively. In 31 of 120 (25.8%) patients diagnoses other than diverticulitis caused abdominal pain, which was correctly diagnosed by MSCT in 71%. The MSCT as well as other concurrently performed diagnostic methods showed normal findings and no causes for the patients symptoms in 22 of the 120 (18.4%) patients. Multi-slice CT is reliable in detecting diverticulitis, including extracolic complications, and often reveals other diagnoses; therefore, MSCT is recommended as standard diagnostic procedure in suspected acute diverticulitis.

Dark-lumen magnetic resonance colonography in patients with suspected sigmoid diverticulitis: a feasibility study.

To assess dark-lumen magnetic resonance colonography (MRC) for the evaluation of patients with suspected sigmoid diverticulitis. Forty patients with suspected sigmoid diverticulitis underwent MRC within 72 h prior to conventional colonoscopy (CC). A three-dimensional T1-weighted volumetric interpolated breath-hold examination sequence was acquired after an aqueous enema and intravenous administration of gadolinium-based contrast agents. All MRC data were evaluated by two radiologists. Based on wall thickness and focal uptake of contrast material and pericolic reaction including mesenteric infiltration on T1-weighted sequence the sigmoid colon was assessed for the presence of diverticulitis. MRC classified 17 of the 40 patients as normal with regard to sigmoid diverticulitis. However, CC confirmed the presence of light inflammatory signs in four patients which were missed in MRC. MRC correctly identified wall thickness and contrast uptake of the sigmoid colon in the other 23 patients. In three of these patients false-positive findings were observed, and MRC classified the inflammation of the sigmoid colon as diverticulitis whereas CC and histopathology confirmed invasive carcinoma. MRC detected additionally relevant pathologies of the entire colon and could be performed in cases where CC was incomplete. MRC may be considered a promising alternative to CC for the detection of sigmoid diverticulitis.

Laparoscopic sigmoid resection for acute and chronic diverticulitis. An outcomes comparison with laparoscopic resection for nondiverticular disease.

BACKGROUND: Sigmoid diverticulitis is a common benign condition; however, cases of acute and chronic diverticulitis may be difficult for the surgeon to treat. We designed a study to compare the outcomes of patients who undergo laparoscopic resections for sigmoid diverticulitis with those who have similar resections for other indications. METHODS: From a prospectively accumulated database of 397 consecutive laparoscopic colorectal procedures performed by three surgeons, we reviewed the outcomes of 178 patients who underwent laparoscopic sigmoid resections with primary anastomosis. RESULTS: Laparoscopic sigmoid colectomies or anterior resections were performed in 22 patients with acute diverticulitis (AD), 70 patients with chronic diverticulitis (CD), and 86 patients with nondiverticular disease (ND). Patients with ND were significantly older than those with AD or CD (67 +/- 14 year versus 55 +/- 13 year, 55 +/- 12 year, p < 0.05). Conversion to open surgery was required in three AD patients (14%), three CD patients (4%), and 17 ND patients (20%) (chi2 = 8.23, p = 0.016). In cases completed laparoscopically, there was no significant difference in median operative time (AD, 165 min; CD, 150 min; ND, 165 min), proportion of patients with intraoperative complications (AD, one; CD, six; ND, one), or postoperative complications (AD, four; CD, 13; ND, 11). The occurrence of a postoperative complication significantly prolonged median time to full diet (4 days vs 3 days, p < 0.001) and discharge (9 days vs 5 days, p < 0.001) but not return to normal activity (16 days vs 15 days). CONCLUSIONS: In this study, patients who underwent laparoscopic sigmoid colectomies and anterior resections had similar outcomes regardless of diagnosis. This finding substantiates our view that laparoscopic resections for diverticulitis can be performed safely and with the same benefits as resections for other indications.

Acute colonic diverticulitis in a community-based hospital: CT evaluation in 138 patients.

The purpose of this research is to retrospectively analyze computed tomography (CT) findings of patients with acute colonic diverticulitis presented to a community-based hospital. During a 1-year period from May 2004 to April 2005, CT scans of 138 patients [mean age 62.3 years (SD 14.9), range 30-100 years] with clinical diagnosis of diverticulitis were analyzed. Of the 138 patients, 136 CT scans were performed with oral and intravenous contrast administration except in two patients who received only oral contrast. Twenty-eight patients (28/138, 20.3%) had diverticulosis, 77 (77/138, 55.8%) had uncomplicated diverticulitis, and 33 (33/138, 23.9%) had complications. Left-sided diverticulitis predominated (137/138, 99.3%). Colonic diverticula were identified in almost every patient (136/138, 98.6%); the majority had moderate colonic wall thickening (82/110, 74.5%) and moderate pericolonic inflammation (65/110, 59.1%). Isolated extraluminal air bubbles (19/33, 57.6%) were the most commonly seen complication, followed by abscess (15/33, 45.5%). Bowel obstruction (2/33, 6.1%) and pylephlebitis (1/33, 3.0%) were less commonly seen but were observed as significant abnormalities. Complicated diverticulitis was less prevalent in this community hospital setting, in contrast with referral medical centers. Common CT findings of diverticulitis included presence of diverticula, moderate wall thickening, and pericolonic inflammation. Isolated air bubbles were the most commonly seen complication followed by abscess.

On-table cecoscopy : a novel diagnostic method in acute diverticulitis of the right colon.

PURPOSE: Controversies abound regarding the optimal surgical management in noncomplicated diverticulitis of the right colon, ranging from a conservative approach to diverticulectomy to right hemicolectomy. One of the arguments for resection is to exclude carcinoma. However, there is significant morbidity associated with resection. We aim to introduce on-table cecoscopy as a tool to improve the diagnosis of acute diverticulitis of the right colon, exclude carcinoma, and reduce the rate of resection. METHODS: From October 1999 to June 2000, five patients presented to our unit with suspected acute appendicitis. Intraoperatively, we found a colonic inflammatory mass at either the cecum or the ascending colon. The cecum and ascending colon were mobilized, and bowel clamps were applied to the ascending colon and ileum. A bronchoscope (Olympus(R) BF-P200) was introduced through the appendix stump. To achieve a good endoscopic view, a limited volume of air was introduced through the working channel. RESULTS: After on-table cecoscopy, all the patients were diagnosed as having acute nonperforated diverticulitis of the right colon. They received appendicectomy, and the diverticulitis was managed conservatively. They were treated with a course of cephalosporin and metronidazole. We performed colonoscopy four weeks later and confirmed that none of them had carcinoma of the colon. CONCLUSIONS: On-table cecoscopy is a new, safe, and effective means of diagnosing acute diverticulitis of the right colon. We can confidently exclude carcinoma and reduce the amount of colonic resection in patients with noncomplicated diverticulitis of the right colon.

Management of diverticulitis in younger patients.

PURPOSE: This study was designed to evaluate the clinical course of sigmoid diverticulitis patients younger than aged 50 years examined by abdominal CT during the first episode of disease to elucidate whether the criteria used for older patients can safely be followed in their younger counterparts. METHODS: Retrospective review of patients with sigmoid diverticulitis treated from 1990 to 2003 was performed. INCLUSION CRITERIA: patients younger than aged 50 years with sigmoid diverticulitis documented by CT scan. Severity of disease was classified according to radiographic findings. Age, gender, treatment, recurrent disease, and need for colostomy were documented. RESULTS: A total of 5,499 patients were identified with sigmoid diverticulitis: 962 patients were younger than aged 50 years, and 411 had a CT scan on their first episode of disease. Of the 411 patients, 335 were classified as uncomplicated and 76 were complicated. Of the uncomplicated patients, 101 underwent an elective operation and 234 were followed nonoperatively. Of those followed, 67 had a recurrent uncomplicated episode, 10 had a recurrent complicated episode, of whom 5 required emergent operation and colostomy. Of the 76 patients with complicated disease, 23 had an emergent operation with colostomy, and 38 had an elective operation. Fifteen patients were followed without an operation and seven had a recurrent uncomplicated episode. None required emergent operation or colostomy. CONCLUSIONS: Younger patients with uncomplicated diverticulitis by CT criteria respond well to medical management and seldom required an emergent operation and colostomy. Young patients with diverticulitis should be treated according to the same criteria used for older patients.
