Aim The study aimed to analyse the currently available national and international guidelines for areas of consensus and contrasting recommendations in the treatment of diverticulitis and thereby to design questions for future research. Method MEDLINE, EMBASE and Pub Med were systematically searched for guidelines on diverticular disease and diverticulitis. Inclusion was confined to papers in English and those < 10 years old. The included topics were classified as consensus or controversy between guidelines, and the highest level of evidence was scored as sufficient (Oxford Centre of Evidence-Based Medicine Level of Evidence of 3a or higher) or insufficient. Results Six guidelines were included and all topics with recommendations were compared. Overall, in 13 topics consensus was reached and 10 topics were regarded as controversial. In five topics, consensus was reached without sufficient evidence and in three topics there was no evidence and no consensus. Clinical staging, the need for intraluminal imaging, dietary restriction, duration of antibiotic treatment, the protocol for abscess treatment, the need for elective surgery in subgroups of patients, the need for surgery after abscess treatment and the level of the proximal resection margin all lack consensus or evidence. Conclusion Evidence on the diagnosis and treatment of diverticular disease and diverticulitis ranged from nonexistent to strong, regardless of consensus. The most relevant research questions were identified and proposed as topics for future research. [ABSTRACT FROM AUTHOR]

Aim This systematic review aimed to evaluate the efficacy, morbidity and mortality of laparoscopic peritoneal lavage for patients with perforated diverticulitis. Method We searched PubMed, EMBASE, Web of Science, the Cochrane Library and CINAHL databases, Google Scholar and five major publisher websites without language restriction. All articles which reported the use of laparoscopic peritoneal lavage for patients with perforated diverticulitis were included. Results Two prospective cohort studies, nine retrospective case series and two case reports reporting 231 patients were selected for data extraction. Most (77%) patients had purulent peritonitis (Hinchey III). Laparoscopic peritoneal lavage successfully controlled abdominal and systemic sepsis in 95.7% of patients. Mortality was 1.7%, morbidity 10.4% and only four (1.7%) of the 231 patients received a colostomy. Conclusion There have been no publications of high methodological quality on laparoscopic peritoneal lavage for patients with perforated colonic diverticulitis. The published papers do, however, show promising results, with high efficacy, low mortality, low morbidity and a minimal need for a colostomy. [ABSTRACT FROM AUTHOR]

The article offers information related to colorectal disease. It says that young patients with acute diverticulitis require urgent surgery during primary admission and hospitalization than older patients. It mentions that the survival of patients who undergo intestinal and multivisceral transplantation are 68% good at one year and 61% at three years.

The article discusses several articles published in different journals. Topics discussed include surgery alone in stage II colon cancer and randomised-controlled trial of 1-year adjuvant chemotherapy with oral tegafur-uracil (UFT), use of primary anastomosis with diverting ileostomy in patients with acute diverticulitis requiring urgent surgery and appetite for exenterating their patients for localised locally advanced rectal cancer.

The article offers information on several article published in different periodicals on topics including colorectal disease, nonantibiotic treatment of uncomplicated diverticulitis, and repairing of ventral hernias (VHR).

Abstract: Aim: Acute uncomplicated diverticulitis (AUD) is common and antibiotics are the cornerstone of traditional conservative management. This approach lacks a clear evidence base and studies have recently suggested that avoidance of antibiotics is a safe and efficacious way to manage AUD. The aim of this systematic review is to determine the safety and efficacy of treating AUD without antibiotics. Method: A systematic search of Embase, Cochrane Library, MEDLINE, Science Citation Index Expanded and ClinicalTrials.gov was performed. Studies comparing antibiotics vs no antibiotics in the treatment of AUD were included. Meta‐analysis was performed using the random effects model with the primary outcome measure being diverticulitis‐associated complications. Secondary outcomes were readmission rate, diverticulitis recurrence, mean hospital stay, requirement for surgery and requirement for percutaneous drainage. Results: Eight studies were included involving 2469 patients: 1626 in the non‐antibiotic group (NAb) and 843 in the antibiotic group (Ab). There was a higher complication rate in the Ab group; however, this was not significant (1.9% vs 2.6%) with a combined risk ratio of 0.63 (95% CI 0.25–1.57, P = 0.32). There was a shorter mean length of hospital stay in the NAb group (standard mean difference −1.18 (95% CI −2.34 to −0.03, P = 0.04). There was no significant difference in readmission, recurrence and surgical intervention rate or requirement for percutaneous drainage. Conclusion: Treatment of AUD without antibiotics may be feasible with outcomes that are comparable to antibiotic treatment and with potential benefits for patients and the National Health Service. Large scale randomized multicentre studies are needed. [ABSTRACT FROM AUTHOR]

Aim The standard of care for acute uncomplicated diverticulitis used to be an elective colon resection after the second or third episode. This practice was replaced by a more conservative and individualized approach. This study investigates current surgical practice in the treatment of acute uncomplicated diverticulitis in Switzerland. Method Retrospective cross-sectional analysis of all hospital admissions due to uncomplicated diverticulitis in Switzerland using prospectively collected data from the Swiss Federal Statistical Office in two periods: 2004/2005 and 2010/2011. Treatment options were compared between the two periods with adjustment for baseline characteristics of patients and treating institutions. Results A total of 24 497 patients (11 835 in 2004/2005; 12 662 in 2010/2011) were admitted to Swiss hospitals for uncomplicated diverticulitis. Between periods, the incidence increased from 81 to 85 admissions per 105 inhabitants per year. Elective admissions decreased from 46% ( n = 5490) to 34% ( n = 4294). The unadjusted resection rate decreased from 40% ( n = 4730) to 34% ( n = 4308). In the adjusted analysis, inpatients were more likely to have a resection in 2010/2011 than in 2004/2005 [odds ratio of 1.38 (95% confidence interval 1.25-1.54)]. In addition, private insurance, elective mode of admission and younger age increased the odds for resection while there was no evidence of an association between resection and either gender or comorbidities. Conclusion The probability of colon resection for patients hospitalized with acute uncomplicated diverticulitis increased between periods while the overall number of colon resections declined. A change of practice expected given the paradigm shift towards conservative treatment could not be confirmed in this analysis. [ABSTRACT FROM AUTHOR]

Aim Immunosuppression is believed to worsen outcomes for patients who require surgery for perforated diverticulitis. The aim of this study was to compare surgical outcomes between immunocompromised and immunocompetent patients undergoing surgery for complicated diverticulitis. Method All patients who underwent emergency surgery for complicated diverticulitis between 2004 and 2012 in a single unit were studied. Patients were classified as immunosuppressed (group I) or immunocompetent (group II). Operation type and postoperative morbidity and mortality were compared between groups. The impact of operating surgeons' specialization and the Peritonitis Severity Score ( PSS) were also evaluated to determine their impact on the restoration of gastrointestinal ( GI) continuity. Results One-hundred and sixteen patients (mean age: 63.7 years), 41.4% women, were included. Fifty-three (45.7%) patients were immunosuppressed (group I): 42 underwent Hartmann's procedure ( HP) (79.2%), nine (17.0%) underwent resection and primary anastomosis ( RPA) with ileostomy ( IL) and two (3.8%) underwent RPA without IL. In group II, 15 HP (23.8%), nine RPA with IL (14.3%) and 39 RPA without IL (61.9%) were performed. Postoperative morbidity and mortality were 79.2% and 26.4%, respectively, in group I and 63.5% and 6.3%, respectively, in group II. The overall mean PSS was 9.5, with a mean PSS of 11.1 in group I and of 8.1 in group II. The decision to perform a primary anastomosis differed significantly between colorectal surgeons and general surgeons in the patients with a PSS of 9-10-11. Conclusion In immunocompromised patients, RPA with IL can be a safe surgical option, whereas HP should be reserved for patients with a PSS of > 11. Colorectal surgical specialization is associated with higher rates of restoration of GI continuity in patients with perforated diverticulitis, especially in patients with an intermediate PSS score. Evaluation of each patient's PSS facilitates decision making in surgery for perforated diverticulitis. [ABSTRACT FROM AUTHOR]

Aim To determine the diagnostic value of serological infection markers and body temperature in discriminating complicated from uncomplicated diverticulitis. Methods Patients in whom diverticulitis was pathologically or radiologically proven at presentation were included. Patients were classified as either complicated (Hinchey Ib, II, III and IV) or uncomplicated (Hinchey Ia) diverticulitis. The discriminative value of C-reactive protein ( CRP), white blood cell ( WBC) count and body temperature at presentation was tested. Results A total of 426 patients were included in this study of which 364 (85%) presented with uncomplicated and 62 (15%) with complicated diverticulitis. Only CRP was of sufficient diagnostic value (area under the curve 0.715). The median CRP in patients with complicated diverticulitis was significantly higher than in patients with uncomplicated disease (224 mg/l, range 99-284 vs 87 mg/l, range 48-151). Patients with a CRP of 25 mg/l had a 15% chance of having complicated diverticulitis. This increased from 23% at a CRP value of 100 mg/l to 47% for 250 mg/l or higher. The optimal threshold was reached at 175 mg/l with a positive predictive value of 36%, negative predictive value of 92%, sensitivity of 61% and a specificity of 82%. Conclusion WBC count and body temperature are of no value in discriminating complicated from uncomplicated diverticulitis. Only CRP can be used as an indicator for the presence of complications, but a low CRP does not mean that complicated disease can safely be excluded. Therefore, radiological examination remains central in the diagnostic work-up of patients presenting with diverticulitis. [ABSTRACT FROM AUTHOR]

Aim This randomized controlled trial (RCT) was performed to test the hypothesis that adverse event rates following primary anastomosis (PRA) are not inferior to those following nonrestorative colon resection for perforated diverticulitis with peritonitis. Method Patients admitted for perforated diverticulitis with peritonitis were randomly assigned to PRA (left colon resection with PRA and loop ileostomy) or nonrestorative colon resection (left colon resection with end colostomy). The endpoint was adverse events defined as mortality and morbidity following PRA or nonrestorative colon resection and stoma reversal. The estimated sample size was 300 patients in each study arm (alpha 0.10; 90% power). Results During a 9-year period, 90 patients were randomly assigned to undergo PRA or nonrestorative colon resection in 14 centres in eight countries. Thirty-four PRA patients were comparable to 56 nonrestorative colon resection patients for age ( P = 0.481), gender ( P = 0.190), APACHE III ( P = 0.281), Hinchey stage III vs IV ( P = 0.394) and Mannheim Peritonitis Index ( P = 0.145). There were no differences in operating time ( P = 0.231), surgeries performed at night ( P = 0.083), open vs laparoscopic approach ( P = 0.419) and litres of peritoneal irrigation ( P = 0.096). There was no significant difference in mortality (2.9 vs 10.7%; P = 0.247) and morbidity (35.3 vs 46.4%; P = 0.38) following PRA or nonrestorative colon resection. After a similar lag time ( P = 0.43), 64.7% of PRA patients and 60% of nonrestorative colon resection patients underwent stoma reversal ( P = 0.659). Adverse event rates following stoma reversal differed significantly after PRA and reversal of nonrestorative resection (4.5 vs 23.5%; P = 0.0589). Conclusion No conclusions may be drawn on preference of one treatment over another from this RCT because it was prematurely terminated following accrual of 15% of its sample size.

Aim Currently in the UK the standard surgical practice for the management of perforated sigmoid diverticulitis is a Hartmann's procedure. There have been a number of recent publications on the use of laparoscopic peritoneal lavage for perforated sigmoid diverticulitis, as an alternative to the emergency Hartmann's procedure, with its associated morbidity and mortality. We aim to review the current literature on this topic. Method A search was made on the electronic database MEDLINE from PubMed, EMBASE and the Cochrane library. The keywords 'diverticulitis', 'perforated' and 'laparoscopy' were searched for in the titles and abstracts without language restrictions. Further studies were identified from searches on Google Scholar, as well as manual searches through reference lists of the relevant studies found. All included studies were quality assessed. Results Twelve relevant studies were included. A total of 301 patients were reported, with a mean age of 57 years. All were non-randomized studies. The majority of patients were of Hinchey classification III. All were treated with intravenous antibiotics followed by laparoscopic lavage and insertion of intra-abdominal/pelvic drains. The mean conversion rate was 4.9% and mean length of hospital stay was 9.3 days. The mean complication rate was 18.9% and the overall mortality rate was 0.25%. Subsequent elective resections with primary anastamosis were performed in 51% of patients and the majority were completed laparoscopically. Conclusion Laparoscopic peritoneal lavage for perforated sigmoid diverticulitis appears to be a potentially effective and more conservative alternative to a Hartmann's procedure. Randomized control trials are needed to better evaluate its role. [ABSTRACT FROM AUTHOR]

Objective We evaluated the prognostic validity of preoperative risk scores in the surgical management of patients with diverticular perforation and diffuse peritonitis. Patients and methods From 1988 to 1998, 82 patients, mean age 72 ± 15 years, underwent urgent surgery for perforated diverticulitis with generalized peritonitis. They were operated either with the Hartmann technique or with resection and primary anastomosis. ASA Classification and Mannheimer Peritonitis Index (MPI) were documented as risk scores at time of surgery and used as guidelines to decide for one of both procedures. Results A Hartmann resection (HA) was performed in 62 patients (76%) and resection with primary anastomosis (PA) in 20 (24%). Seventy-one percent of patients in the HA group corresponded to ASA IV/V, compared with 35% in the group with primary anastomosis (P < 0.001). Patients with Hartmann resection had also a higher MPI (23 ± 8) vs those with primary anastomosis (18 ± 7; P < 0.004). However, differences between the HA group and the PA group due to post-operative morbidity (21% vs 35%) and mortality (35% vs 20%) did not reach statistical significance. Nevertheless, multivariate analysis of the whole series revealed a significant relationship between MPI and mortality (P < 0.0043), independent of ASA class, age and operative procedure. Conclusion Patients assigned to Hartmann procedure had more co-morbidities and more advanced peritonitis as assessed by increased ASA and higher MPI. The Mannheimer Peritonitis Index proved to be an independent prognostic index in estimating mortality with respect to peritonitis extension and septic status of the patient. [ABSTRACT FROM AUTHOR]

The article focuses on whether the method of surgical access to the abdomen determine treatment in perforated diverticulitis. Patients with perforated diverticulitis should undergo primary resection or nonresectional surgery regardless of the surgical access to the abdomen. The findings should be the basis of the treatment of perforated diverticulitis patients.
