Uncomplicated acute diverticulitis of the cecum and ascending colon: sonographic findings in 18 patients.

To determine the sonographic features of uncomplicated acute diverticulitis of the cecum and ascending colon, the sonographic findings in 534 patients who presented with right lower quadrant pain were reviewed. Of these, 18 patients had uncomplicated acute diverticulitis of the cecum and ascending colon. The diagnosis was confirmed by surgery (one patient), clinical course (17 patients), CT (eight patients), or contrast enema (11 patients). On sonography, a round or oval focus of varying echogenicity, which protruded from a segmentally thickened colonic wall and was surrounded by a hyperechoic area, was seen in all 18 patients. These were hypoechoic foci (12 patients), hypoechoic foci with internal strong echoes (three patients), and echogenic shadowing foci with surrounding hypoechoic bands (three patients). Extraluminal gas (one patient) and thickening of lateroconal fascia (six patients) were seen also. Findings of enlarged appendix, frank abscess, and ascites were absent. All patients, including the one who had laparotomy, were successfully treated medically for diverticulitis. Of 515 patients without diverticulitis, in only one patient with acute appendicitis did sonography show a hypoechoic protruding focus. Our experience indicates that the major sonographic finding in patients with uncomplicated acute diverticulitis of the right colon is a hypoechoic round or oval focus protruding from a segmentally thickened colonic wall.

Elective surgery after acute diverticulitis.

BACKGROUND: Diverticulitis is a common condition. Practice guidelines from many organizations recommend bowel resection after two attacks. The evidence for such a recommendation is reviewed. METHODS: A Medline literature search was performed to locate English language articles on surgery for diverticular disease. Further articles were obtained from the references cited in the literature initially reviewed. RESULTS: Most people with diverticulosis are asymptomatic. Diverticular disease occurs in over 25 per cent of the population, increasing with age. After one episode of diverticulitis one-third of patients have recurrent symptoms; after a second episode a further third have a subsequent episode. Perforation is commonest during the first episode of acute diverticulitis. After recovering from an episode of diverticulitis the risk of an individual requiring an urgent Hartmann's procedure is one in 2000 patient-years of follow-up. Surgery for diverticular disease has a high complication rate and 25 per cent of patients have ongoing symptoms after bowel resection. CONCLUSION: There is no evidence to support the idea that elective surgery should follow two attacks of diverticulitis. Further prospective trials are required.

Early water-soluble contrast enema in the diagnosis of acute colonic diverticulitis.

Acute colonic diverticulitis is usually suspected by typical clinical findings supported by laboratory tests. Investigations of the colon are usually delayed 1 to 2 months until the acute situation is resolved. We studied 53 patients with an initial clinical diagnosis of acute diverticulitis by performing early water-soluble contrast enema of the colon. The initial diagnosis proved to be uncertain, as 26 patients (49%) had acute colonic diverticulitis as their final diagnosis. There were ten patients who had diverticulosis of the colon, but without radiologic signs of acute diverticulitis. Four of these patients had some other disease responsible for their symptoms. Thirteen patients had normal findings at early water-soluble contrast enema. Three colonic carcinomas and one ischaemic colitis were diagnosed. There were no complications related to the radiologic studies. We conclude that early water-soluble contrast edema of the left colon is safe and useful in investigating patients with suspected acute colonic diverticulitis. If the finding is normal, investigations can be directed elsewhere without undue delay.

Acute colonic diverticulitis in the young.

BACKGROUND: Colonic diverticulitis in the young has been considered to have a virulent course, high morbidity, and high operative rate. As a result, elective resection of the involved colonic segment after the first clinical episode has been the usual practice. PURPOSE: This study presents our experience with acute diverticulitis in the young. METHODS: In the last nine years, 63 patients younger than 45 years were treated for acute diverticulitis at our institution. A retrospective review was performed to determine the clinical course and outcome of these patients. RESULTS: Clinical presentations, radiographic tests, operative findings, and pathology results revealed that 57 patients had a pericolonic contained disease (Hinchey State I). Two patients had a large pelvic abscess (Hinchey Stage II), and four patients had a diffuse peritonitis (Hinchey Stage III). Forty-one patients (65 percent) were successfully treated medically with antibiotics and bowel rest. Of 22 patients (35 percent) who underwent emergent operations, 12 patients' diseases had been erroneously diagnosed preoperatively (9 "appendicitis"). CONCLUSION: Diverticulitis at a young age does not have a specific aggressive nature. Although, it is associated with a high rate of emergency operations, many of these are performed for a mistaken diagnosis. The recommendation for routine elective resection following the first episode of diverticulitis should be reassessed.

Transverse colon diverticulitis: successful nonoperative management in four patients. Report of four cases.

PURPOSE: Diverticulitis of the transverse colon is a rare disorder and is often confused with other conditions. Previously reported cases of transverse colon diverticulitis were diagnosed and treated by surgical exploration. Four cases are presented that were successfully managed with a nonsurgical approach. METHODS AND RESULTS: Review of the literature in English disclosed 31 cases of transverse colon diverticulitis. The clinical characteristics and management of these patients are reviewed and compared with the current series of patients. The utility of computerized tomography in the diagnosis of diverticulitis is discussed. CONCLUSIONS: Medical therapy with bowel rest and antibiotics is appropriate for transverse colon diverticulitis when free perforation and peritoneal signs are absent and the inflammation is contained, as shown by computerized tomography. Operative exploration should be reserved for patients with diffuse peritonitis or those where perforated colon cancer cannot be excluded.

Timing of computed tomography in acute diverticulitis.

PURPOSE: The purpose of this study was to evaluate the use and timing of computed tomography in the treatment of patients with acute left-sided diverticulitis. METHODS: We reviewed our four-year experience of 47 patients with the diagnosis of acute diverticulitis. We have evaluated the benefits of admission vs. delayed computed tomography in patients with this diagnosis. RESULTS: Of the 47 patients, 17 were diagnosed on clinical grounds alone, treated, and released. Thirty patients had their clinical diagnoses of diverticulitis evaluated with either computed tomographic scan (26) or laparotomy (4). Eleven of those 30 (36 percent) patients were found to have normal computed tomographic scans, indicating inaccurate clinical diagnosis, and all patients who underwent laparotomy had the pathologic diagnosis of diverticulitis. Six of the 47 patients had abscesses, but only 2 were identified at the time of admission. The remaining four abscesses were identified on delayed computed tomographic scans after failure of medical therapy. Thirty-seven hospital days were used by patients with inaccurate diagnoses before their computed tomographic scans. Analysis of cost revealed that a computed tomographic scan for all 47 patients would have cost less than the expense of admission for just the 11 patients who had normal computed tomographic scans. CONCLUSION: Routine admission computed tomographic scan for patients with acute diverticulitis leads to more accurate diagnosis, earlier identification of complications, and possible decreased hospital costs.

Feasibility of MRI in the diagnosis of acute diverticulitis: initial results.

PURPOSE: The purpose of this study was to evaluate MRI as a diagnostic tool in patients with suspected acute sigmoid diverticulitis. Furthermore, we sought to develop an optimal imaging protocol in these patients. PATIENTS AND METHODS: Eleven patients with suspected acute diverticulitis were included in the study. All patients were imaged in a 1.0 T clinical scanner using a body-array coil. Imaging sequences were single-shot TSE, HASTE-, STIR- and TrueFisp- sequence. All were obtained in the frontal plane. The diagnosis was verified by a single experienced investigator, using ultrasound, and overall clinicopathological outcome. RESULTS: MRI enabled visualization of signs of an acute diverticulitis in all patients. However, the diagnosis of acute diverticulitis was obtained in 10 patients only. The mean imaging time was 17.5+/-5.5 min. STIR- and TrueFisp-sequences alone displayed all findings, e.g pericolonic exsudation, edema and segmental narrowing, whereas SSTSE and HASTE-sequences showed no additional information. Therefore, it appeared that the imaging protocol could be restricted to STIR- and TrueFisp-sequences. CONCLUSION: MRI is feasible as a fast, accurate and investigator-independent diagnostic tool in patients with suspected acute diverticulitis. To prove its value in comparison to computed tomography or ultrasound, further studies are needed.

[Sigmoid diverticulitis. Surgical indications and timing].

Indication and time for surgery of diverticular disease are determined by the stage of the disease. Clinically pragmatic pretreatment staging is thus a prerequisite for stage-adapted therapy. The correct indication for surgery is also based on knowledge of the spontaneous disease course, its course after conservative and operative therapy and the individual risk factors for complicated diverticular disease. Surgery is not indicated for bland diverticulosis or uncomplicated diverticulitis. It is generally indicated, however, for acute complicated diverticulitis. Decisive in establishing the indication for surgery is therefore the precise pretherapeutic differentiation of complicated and uncomplicated diverticulitis. Depending on the type of complication and the clinical appearance, the time for surgery of acute complicated diverticulitis is fixed on an emergency or early elective basis following initial conservative and/or interventional therapy. Chronically recurrent diverticulitis is likewise an indication for surgery. In terms of timing, an elective interval operation is best after the second inflammatory episode but should already be performed after the first one in risk groups, e.g. immunosuppressed patients.

[Multiple recurrent perforated jejunal diverticulitis].

Jejunal diverticulitis is a very rare cause of acute abdomen. The treatment of choice in acute perforated jejunal diverticulitis is intestinal resection with primary anastomosis of the affected area. Data on long-term results, postoperative complications and the nature of this illness is limited. To our knowledge, a recurrent perforated jejunal diverticulitis has never have been reported in the literature. In this case,we present a patient who suffered from a recurrence of perforated jejunal diverticulitis 13 weeks after the initial intestinal resection. After the second intestinal resection (due to the recurrent infection), the patient suffered from a third period of jejunal diverticulitis.

Resection and primary anastomosis in acute complicated diverticulitis, a systematic review of the literature.

OBJECTIVE: To determine the safety and feasibility of primary resection and anastomosis with or without a diverting stoma, as compared to Hartmann's procedure, for patients with acute complicated sigmoid diverticulitis. SEARCH STRATEGY: MEDLINE was searched for studies and trials conducted between 1966 and December 2003. This search revealed trials comparing primary resection and anastomosis to Hartmann's procedure. The term "diverticulitis, colonic" with the sub-heading "surgery" was used and the search was limited to human studies and clinical trials. Additional studies were found using the MeSH terms: "surgical procedures, operative", "surgical anastomosis", and "Hartmann procedure", combined with the term "diverticulitis, colonic". The author also searched EMBASE and the Cochrane database for clinical trials using similar terminology. No language restrictions were applied. RESULTS: Eighteen studies met the inclusion criteria and reported 884 patients with acute complicated diverticulitis. None of these studies were randomised; it is likely that there was a significant degree of selection bias. No significant differences were found between primary resection with anastomosis and Hartmann's procedure with respect to mortality, morbidity, sepsis, wound complications and duration of procedure and anti-biotic treatment. Some studies found that primary anastomosis and a protecting stoma, with or without intra-operative colonic lavage, have more favourable results than Hartmann's procedure. CONCLUSIONS: This review suggests that surgical resection and primary anastomosis in acute diverticulitis with peritonitis compares favourably with Hartmann's procedure in terms of peri-operative complications. The need for revision of Hartmann's procedure could be subsequently avoided. Some articles showed that patients with severe peritonitis, who had a diverting stoma, in the setting of resection and primary anastomosis, had the lowest complication rate. However, the quality of these studies was poor with the presence of selection bias.

Laparoscopic colectomy for recurrent and complicated diverticulitis: a prospective study of 396 patients.

BACKGROUND: It was the aim of this prospective study to evaluate the outcome of laparoscopic surgery for diverticular disease. METHODS: All patients who underwent elective laparoscopic colectomy for diverticular disease within a 10-year period were prospectively entered into a PC database registry. Indications for laparoscopic surgery were acute complicated diverticulitis (Hinchey stages I and IIa), chronically recurrent diverticulitis, sigmoid stenosis or outlet obstruction caused by chronic diverticulitis. Surgical procedures (sigmoid and anterior resection, left colectomy and resection rectopexy) included intracorporeal dissection and colorectal anastomosis. Parameters studied included age, gender, stage of disease, procedure, duration of surgery, intraoperative technical variables, transfusion requirements, conversion rate, total complication rate including major (requiring re-operation), minor (conservative treatment) and late-onset (post-discharge) complication rates, stay on ICU, hospitalisation, mortality, and recurrence. For objective evaluation, only laparoscopically completed procedures were analysed. Comparative outcome analysis was performed with respect to stage of disease and experience. RESULTS: A total of 396 patients underwent laparoscopic colectomy. Conversion rate was 6.8% ( n=27), so that laparoscopic completion rate was 93.2% ( n=369). Most common reasons for conversion were directly related to the inflammatory process, abscess or fistulas. The most common procedure was sigmoid resection ( n=279), followed by anterior resection ( n=36) and left colectomy ( n=29). Total complication rate was 18.4% ( n=68). Major complication rate was 7.6% ( n=28), whereas the most common complication requiring re-operation was haemorrhage in 3.3% ( n=12). Anastomotic leakage occurred in 1.6% ( n=6). Minor complications were noted in 10.7% ( n=40), late-onset complications occurred in 2.7% ( n=10). Mortality was 0.5% ( n=2). Mean duration of surgery was 193 (range 75-400) min, return to normal diet was completed after 6.8 (range 3-19) days. Mean hospital stay was 11.8 (range 4-71) days. No recurrence of diverticulitis occurred. CONCLUSION: Laparoscopic surgery for diverticular disease is safe, feasible and effective. Therefore, laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis at our institution.

Diverticulitis causing a high serum level of carbohydrate antigen 19-9: report of a case.

We report herein a rare case of diverticulitis causing a high serum level of carbohydrate antigen (CA) 19-9. A 52-year-old man was admitted to our hospital with lower abdominal pain. Laboratory data showed evidence of inflammation and a high serum level of CA 19-9 (370 U/ml). Computed tomography demonstrated thickening of the wall of the sigmoid colon. He was diagnosed as having diverticulitis of the sigmoid colon and was treated with antibiotics. Although his symptoms improved, the presence of a malignancy such as colorectal cancer could not be completely ruled out because of the persistently high serum level of CA 19-9. A laparotomy was performed and the sigmoid colon was found to be adherent to the bladder. Under a diagnosis of diverticulitis, a sigmoidectomy was performed. Pathological examination revealed diverticulitis of the sigmoid colon, but there was no evidence of malignancy in the resected specimen. The serum CA 19-9 level decreased to normal postoperatively and immunohistochemical staining revealed CA 19-9 antigen in the cytoplasm of the diverticular epithelium. Therefore, a possible explanation for the high level of this tumor marker was diverticulitis of the sigmoid colon.

Laparoscopic approach to treatment of sigmoid diverticulitis: changes in the spectrum of indications and results of a prospective, multicenter study on 1,545 patients.

BACKGROUND: The aim of the present study was to analyze changes regarding the indications for and results of laparoscopic treatment of sigmoid diverticulitis. METHODS: The data were collected within the framework of an ongoing prospective multicenter study carried out by the Lapa roscopic Colorectal Surgery Study Group and were submitted to a statistical subgroup analysis. The institutions participating in the study were divided into three groups by experience (Group I, >100 procedures; Group II, 30-100 procedures; Group III, < 30 procedures). RESULTS: Among the 3,868 recruited patients, sigmoid diverticulitis (n = 1,545, 40 percent) was by far the most common indication for surgery, and sigmoid resection (n = 2,160, 55.9 percent) was by far the most common laparoscopic procedure. A total of 1,353 patients (87.6 percent) had uncomplicated diverticulitis, whereas 192 (12.4 percent) had a complicated form of diverticular disease (Hinchey I-IV, diverticular bleeding, fistula formation). Cases of complicated diverticulitis were significantly more frequently operated on at institutions with greater experience (Group I, 20.8 percent; Group II, 8.7 percent; Group III, 7.9 percent). Despite this fact, these institutions still had better intraoperative complication rates (Group I, 5.0 percent; Group II, 5.8 percent; Group III, 6.9 percent), conversion rates (Group I, 4.4 percent; Group II, 6.7 percent; Group III, 7.7 percent), and postoperative morbidity (Group I, 15.9 percent; Group II, 16.6 percent; Group III, 18.6 percent) and mortality (Group I, 0.2 percent; Group II, 0.5 percent; Group III, 0.4 percent) rates. CONCLUSION: An increase in experience is associated with an expansion of laparoscopic indications to include complicated forms of diverticulitis, with comparable ntraoperative and postoperative complication rates, operating time, and mortality rates.

Hartmann's colectomy and reversal in diverticulitis: a population-level assessment.

PURPOSE: This study was designed to assess the costs and outcomes of colostomy and colostomy reversal in patients with diverticulitis and examine the impact of such procedures on the health care system. METHODS: We employed a retrospective design and used a Washington State administrative database to identify patients undergoing operations with colostomy (1987-2002) who were followed over time. Descriptive and comparative analysis was performed, focusing on patients with diverticulitis. RESULTS: There were 16,556 patients who underwent colostomy and 5,420 (32.7 percent) were for diverticulitis and its related complications (mean age, 64.8 +/- 15.1 years; 53.2 percent female). In patients with diverticulitis, the rate of colostomy reversal was 56.3 percent (80 percent in patients less than 50 years, and 30 percent in patients over 77 years). The in-hospital mortality rate after colostomy reversal was 0.36 percent, and was 2.6 percent in those over 77 years of age. After colostomy reversal a second stoma was used in 3.4 percent, reoperation was required for bleeding complications in 0.6 percent, and infectious complications were noted in 2 percent. The length of time from colostomy to its reversal was approximately five months (138.1 +/- 164 days; interquartile range, 72-156). The relationship between the length of time from colostomy to reversal was evaluated and the adjusted odds of a second stoma being used at the time of colostomy reversal were 45 percent higher (odds ratio, 1.45; 95 percent confidence interval, 1.22, 1.73) for each increase in time interval (<3, 6-9, 9-12, >12 months). CONCLUSIONS: One-third of all colostomies were related to diverticulitis and only 56 percent were reversed. We identified a higher than expected mortality rate among older patients undergoing colostomy reversal. The impact of colostomy and reversal operations on both patients and the health care system is significant.

Toward therapeutic guidelines for patients with acute right colonic diverticulitis.

BACKGROUND: At present, little information is available on the outcome of medical therapy for patients with acute right colonic diverticulitis, and this has meant a gap in constructing guidelines for its treatment. METHODS: The records of patients with acute right colonic diverticulitis at Nagasaki University Graduate School and affiliated hospitals were reviewed and analyzed with the goal of establishing therapeutic guidelines. The time frame of the data analyzed was from 1984 to 2002. RESULTS: Of the 81 patients included in the data, 80 patients who were suffering a first attack were successfully treated with bowel rest and antibiotics. Two of these 80 patients underwent an elective operation at the surgeon's discretion during the original hospitalization and 1 (1.2%) needed an urgent operation. Of the 78 patients who responded to medical therapy, 16 (20.5%) developed recurrent right colonic diverticulitis. All 16 patients who had a second attack were successfully treated with medical therapy. Three of the 16 patients underwent an elective operation during this rehospitalization period. Of the 13 patients who had had a second attack and had responded to medical therapy, there was a third attack in 2 patients (15.4%). Both of these patients were again successfully treated with medical therapy. There has been no morbidity and no mortality related to recurrence to date. The average time from the first attack to us contacting the patient was 35.2 months. CONCLUSIONS: Unlike acute uncomplicated left colonic diverticulitis, our findings indicate that after two documented episodes, medical treatment alone rather than elective surgery may be considered as an effective guideline for the treatment of acute uncomplicated right colonic diverticulitis.

Temporal changes in the management of diverticulitis.

PURPOSE: This study was designed to evaluate temporal trends in the use and type of operative and non-operative interventions in the management of diverticulitis. METHODS: A retrospective cohort using a statewide administrative database was used to identify all patients hospitalized for diverticulitis in the state of Washington (1987-2001). Poisson and logistic regression were used to calculate changes in the frequency of hospitalization, operative and percutaneous interventions, and colostomy over time. RESULTS: Of the 25,058 patients hospitalized non-electively with diverticulitis (mean age 69 +/- 16, 60% female) there were only minimal changes in the frequency of admissions over time (0.006% increase per year-IRR 1.00006 95% CI 1.00004, 1.00008). The odds of an emergency colectomy at initial hospitalization decreased by 2% each year (OR 0.98 95% CI 0.98, 0.99) whereas the odds of percutaneous abscess drainage increased 7% per year (OR 1.07 95% CI 1.05, 1.1). Among patients undergoing percutaneous drainage, the odds of operative interventions decreased by 9% compared to patients who did not have a percutaneous intervention (OR 0.91 95% CI 0.87, 0.94). The proportion of patients undergoing colostomy during emergency operations remained essentially stable over time (range 49-61%), as did the proportion of patients undergoing prophylactic colectomy after initial non-surgical management (approximately 10%). CONCLUSIONS: There was a minimal increase in the frequency of diverticulitis admissions over time. A rise in percutaneous drainage procedures was associated with a decrease in emergency operative interventions. The proportion of patients undergoing colostomy remained stable, and there does not seem to be a significant increase in the use of one-stage procedures for diverticulitis.

CT of diverticulitis and alternative conditions.

The clinical diagnosis of diverticulitis is often uncertain and frequently incorrect. Diagnostic imaging such as with helical CT offers a rapid and accurate diagnosis of diverticulitis and its complications as well as alternative conditions. In particular, helical CT combined with contrast material administered through the colon is highly accurate and can be obtained quickly. CT signs of diverticulitis include focal inflammatory wall thickening and paracolic inflammation superimposed on diverticular disease (diverticula, muscular wall hypertrophy). Common alternative conditions that can clinically mimic diverticulitis include small bowel obstruction, primary epiploic appendagitis, acute cholecystitis, appendicitis, ileitis, ovarian cystic disease, and ureteral stone disease. Early and frequent use of diverticular CT promises to improve diagnosis and treatment of patients with clinically suspected diverticulitis.

Diagnosis and differential diagnosis of colonic diverticulitis.

A patient over 40 years of age who complains of lower abdominal pain, constipation or diarrhea or both, and increased flatulence should be suspected of having diverticulosis. When pain becomes more severe and persistent, diverticulitis must be considered. Diagnosis depends on roentgen demonstration of the presence of diverticula. Sigmoidoscopy and barium enema study are essential to exclude coexisting disease but in diverticulitis may need to be postponed until severe local and systemic signs of inflammation have subsided. A number of diseases can simulate diverticulitis, and differential diagnosis may present considerable difficulty. Irritable colon syndrome and acute appendicitis may be indistinguishable clinically from diverticulitis. Differentiation from carcinoma is usually not difficult, but exclusion of coexistent carcinoma may be impossible except by resection. Ulcerative colitis is also easily distinguished except when, rarely, it coexists. Crohn's disease of the colon is less easily differentiated, especially in patients over 40, in whom the two diseases often coexist. Other colonic diseases, such as ischemic colitis, and pelvic inflammatory diseases usually show characteristic features which make them readily distinguishable from diverticulitis.
