ABSTRACT

BACKGROUND: Present theory is that uncomplicated and complicated appendicitis are different entities. Recent studies suggest it is safe to delay surgery in patients with uncomplicated appendicitis. We hypothesize that patients with complicated appendicitis are at higher risk for postoperative complications when surgery is delayed. METHODS: Data was used from the multicenter, prospective SNAPSHOT appendicitis study of 1975 patients undergoing surgery for suspected appendicitis. Adult patients (≥ 18 years) who underwent appendectomy for appendicitis were included in this study. The primary outcome was the difference in postoperative complications between patients with complicated appendicitis who were operated within and after 8 h after hospital presentation. Secondary outcomes were the incidence of both uncomplicated and complicated appendicitis in relationship to delay of appendectomy. Follow-up was 30 days. A multivariable analysis was performed. RESULTS: Of 1341 adult patients with appendicitis, 34.3% had complicated appendicitis. In patients with complicated appendicitis, 22.8% developed a postoperative complication compared to 8.2% for uncomplicated appendicitis (P < 0.001). Delay in surgery (> 8 h) increased the complication rate in patients with complicated appendicitis (28.1%) compared to surgery within 8 h (18.3%; P = 0.01). Multivariate analysis showed a delay in surgery as an independent predictor for a postoperative complication in patients with complicated appendicitis (OR 1.71; 95%CI 1.01-2.68, P = 0.02). CONCLUSION: In-hospital delay of surgery (> 8 h) in patients with complicated appendicitis is associated with a higher risk of a postoperative complication. It is important that we recognize and treat these patients early.

ABSTRACT

BACKGROUND: Laparoscopic, robot-assisted, and transanal total mesorectal excision are the minimally invasive techniques used most for rectal cancer surgery. Because data regarding oncologic results are lacking, this study aimed to compare these three techniques while taking the learning curve into account. METHODS: This retrospective population-based study cohort included all patients between 2015 and 2017 who underwent a low anterior resection at 11 dedicated centers that had completed the learning curve of the specific technique. The primary outcome was overall survival (OS) during a 3-year follow-up period. The secondary outcomes were 3-year disease-free survival (DFS) and 3-year local recurrence rate. Statistical analysis was performed using Cox-regression. RESULTS: The 617 patients enrolled in the study included 252 who underwent a laparoscopic resection, 205 who underwent a robot-assisted resection, and 160 who underwent a transanal low anterior resection. The oncologic outcomes were equal between the three techniques. The 3-year OS rate was 90% for laparoscopic resection, 90.4% for robot-assisted resection, and 87.6% for transanal low anterior resection. The 3-year DFS rate was 77.8% for laparoscopic resection, 75.8% for robot-assisted resection, and 78.8% for transanal low anterior resection. The 3-year local recurrence rate was in 6.1% for laparoscopic resection, 6.4% for robot-assisted resection, and 5.7% for transanal procedures. Cox-regression did not show a significant difference between the techniques while taking confounders into account. CONCLUSION: The oncologic results during the 3-year follow-up were good and comparable between laparoscopic, robot-assisted, and transanal total mesorectal technique at experienced centers. These techniques can be performed safely in experienced hands.

ABSTRACT

BACKGROUND: Non-operative treatment of uncomplicated appendicitis is safe and increasing in popularity, but has other risks and benefits compared with appendicectomy. This study aimed to explore the preference of the general population regarding operative or antibiotic treatment of uncomplicated appendicitis. METHODS: In this prospective study, a clinical scenario and questionnaire were submitted to a panel comprising a sample of an average adult population. The survey was distributed by an independent, external research bureau, and included a comprehensive explanation of the risks and benefits of both treatment options. The primary outcome was the proportion of participants who would prefer antibiotics over surgery. Secondary outcomes were reasons for this preference and the accepted recurrence rate within 1 year when treated with antibiotics only. All outcomes were weighted for the average Dutch population. RESULTS: Of 254 participants, 49.2 per cent preferred antibiotic treatment for uncomplicated appendicitis, 44.5 per cent preferred surgery, and 6.3 per cent could not make a decision. About half of the participants preferring antibiotics would accept a recurrence risk of more than 50 per cent within 1 year. Avoiding surgery was their main reason. In participants preferring surgery, many tolerated a recurrence risk of no more than 10 per cent when treated with antibiotics. Removal of the cause of appendicitis was their main reason. CONCLUSION: Around half of the average population sample preferred antibiotics over surgical treatment of uncomplicated appendicitis and were willing to accept a high recurrence risk to avoid surgery initially. Participants who preferred surgery tolerated only a very low recurrence risk with antibiotic treatment.

ABSTRACT

BACKGROUND: The aim of this study was to compare perineal wound healing between gluteal turnover flap and primary closure in patients undergoing abdominoperineal resection (APR) for rectal cancer. METHODS: Patients who underwent APR for primary or recurrent rectal cancer with gluteal turnover flap in two university hospitals (2016-2021) were compared to a multicentre cohort of primary closure (2000-2017). The primary endpoint was uncomplicated perineal wound healing within 30 days. Secondary endpoints were long-term wound healing, related re-interventions, and perineal herniation. The perineal hernia rate was assessed using Kaplan Meier analysis. RESULTS: Twenty-five patients had a gluteal turnover flap and 194 had primary closure. The uncomplicated perineal wound-healing rate within 30 days was 68% (17/25) after gluteal turnover flap versus 64% (124/194) after primary closure, OR 2.246; 95% CI 0.734-6.876; p = 0.156 in multivariable analysis. No major wound complications requiring surgical re-intervention occurred after flap closure. Eighteen patients with gluteal turnover flap completed 12-month follow-up, and none of them had chronic perineal sinus, compared to 6% (11/173) after primary closure (p = 0.604). The symptomatic 18-month perineal hernia rate after flap closure was 0%, compared to 9% after primary closure (p = 0.184). CONCLUSIONS: The uncomplicated perineal wound-healing rate after the gluteal turnover flap and primary closure after APR is similar, and no chronic perineal sinus or perineal hernia occurred after flap closure. Future studies have to confirm potential benefits of the gluteal turnover flap.

ABSTRACT

PURPOSE: For the diagnosis of acute appendicitis, the combination of clinical and laboratory variables achieves high diagnostic accuracy. Nevertheless, appendicitis can present with normal laboratory tests of inflammation. The aim of this study was to investigate the incidence of normal inflammatory markers in patients operated for acute appendicitis. METHODS: This is an analysis of data from a prospective, multicentre SNAPSHOT cohort study of patients with suspected acute appendicitis. Only patients with histopathologically proven acute appendicitis were included. Adult patients with acute appendicitis and normal preoperative inflammatory markers were explored further in terms of abdominal complaints, preoperative imaging results and intraoperative assessment of the degree of inflammation and compared to those with elevated inflammatory markers. RESULTS: Between June and July 2014, 1303 adult patients with histopathologically proven acute appendicitis were included. In only 23 of 1303 patients (1.8%) with proven appendicitis, both preoperative white blood cell count and C-reactive protein levels were normal. Migration of pain was reported less frequently in patients with normal inflammatory markers compared to those with elevated inflammatory marker levels (17.4% versus 43.0%, p = 0.01). Characteristics like fever, duration of symptoms and localized peritonitis were comparable. Only 4 patients with normal inflammatory markers (0.3% overall) had complicated appendicitis at histopathological evaluation. CONCLUSION: Combined normal WBC and CRP levels are seen in about 2 per 100 patients with confirmed acute appendicitis and can, although rarely, be found in patients with complicated appendicitis.

ABSTRACT

BACKGROUND: Discriminating complicated from uncomplicated appendicitis is crucial. Patients with suspected complicated appendicitis are best treated by emergency surgery, whereas those with uncomplicated appendicitis may be treated with antibiotics alone. This study aimed to obtain summary estimates of the accuracy of ultrasound imaging, CT and MRI in discriminating complicated from uncomplicated appendicitis. METHODS: A systematic literature review was conducted by an electronic search in PubMed, Embase and the Cochrane Library for studies describing the diagnostic accuracy of complicated versus uncomplicated appendicitis. Studies were included if the population comprised adults, and surgery or pathology was used as a reference standard. Risk of bias and applicability were assessed with QUADAS-2. Bivariable logitnormal random-effect models were used to estimate mean sensitivity and specificity. RESULTS: Two studies reporting on ultrasound imaging, 11 studies on CT, one on MRI, and one on ultrasonography with conditional CT were included. Summary estimates for sensitivity and specificity in detecting complicated appendicitis could be calculated only for CT, because of lack of data for the other imaging modalities. For CT, mean sensitivity was 78 (95 per cent c.i. 64 to 88) per cent, and mean specificity was 91 (85 to 99) per cent. At a median prevalence of 25 per cent, the positive predictive value of CT for complicated appendicitis would be 74 per cent and its negative predictive value 93 per cent. CONCLUSION: Ultrasound imaging, CT and MRI have limitations in discriminating between complicated and uncomplicated appendicitis. Although CT has far from perfect sensitivity, its negative predictive value for complicated appendicitis is high.

ABSTRACT

INTRODUCTION: In patients treated with an appendectomy for acute appendicitis, the specimen is generally sent for histological evaluation. In an era of increasing non-operative treatment for acute appendicitis, it is important to know the incidence, the diagnostic accuracy, and treatment consequences of appendicular neoplasms that are found in acute appendicitis. We hypothesize that pre- and intra-operative parameters might predict an appendicular neoplasm. METHODS: Data was used from our previous prospective observational cohort study. All patients undergoing surgery for suspected acute appendicitis were included. The primary outcome was the incidence of appendicular neoplasms in patients operated for acute appendicitis. Secondary outcomes were pre-operative diagnostics and imaging outcomes, intra-operative surgical judgment, and postoperative management and outcome. Possible predictors of an appendicular neoplasm were identified and used in multivariable logistic regression. Patients with an appendicular neoplasm were followed for 3 years after initial appendectomy. RESULTS: A total of 1975 patients underwent surgery for suspected acute appendicitis and in 98.3% (1941/1975) the appendix was removed. In 1.5% (30/1941) of these patients, an appendicular neoplasm was found. Among the malignant neoplasms, the majority were grade 1 neuroendocrine tumors (NET) in 65% (13/20). On pre-operative imaging, there was no suspicion of malignancy. In three cases, there was an intra-operative suspicion of malignancy. Multivariable analysis showed only age as an independent predictor for appendicular neoplasms. No recurrent or new malignancy was found during follow-up. DISCUSSION: The incidence of appendicular neoplasm in patients undergoing an acute appendectomy is very low and clinical risk factors could not be identified.

ABSTRACT

AIM: Connective tissue changes due to ageing or diseases leading to changes in the colonic wall are one theory for the development of diverticula. Alpha-1-antitrypsin (A1AT), a protease inhibitor that protects connective tissue, possibly plays a role in the aetiology of diverticulosis. The aim of this study was to explore associations between the development of diverticula and A1AT deficiency. METHODS: This was a multicentre prospective case-control study. A total of 221 patients aged ≥ 60 years with acute abdominal pain undergoing abdominal CT were included and analysed. Patients with diverticula were defined as the research group, patients without diverticula as controls. Genotype analysis for A1AT deficiency was performed. RESULTS: Twenty-six of 221 (11.8%) patients were diagnosed with (being a carrier of) A1AT deficiency. A non-significant difference in prevalence between patients with and without diverticula was found, 20 (13.9%) of 144 vs 6 (7.8%) of 77, respectively, with a crude OR of 1.9 (95% CI 0.7-5.0; P = 0.186) and after adjustment for confounders an adjusted OR of 1.5 (95% CI 0.5-4.0; P = 0.466). A non-significant difference in 30-day mortality rate from acute diverticulitis between A1AT deficient patients (or carriers) and those without was observed: two (22.2%) of nine patients with A1AT deficiency vs 1 (1.8%) of 55 without. CONCLUSION: We found no convincing evidence that A1AT deficiency plays a role in the aetiology of diverticulitis, although deficient patients and carriers had a higher mortality when experiencing diverticulitis. Diverticulitis is a multifactorial disease and larger numbers may be needed to explore the role of A1AT deficiency among other contributing factors.

ABSTRACT

AIM: This study aimed to determine predictive factors for the circumferential resection margin (CRM) within two northern European countries with supposed similarity in providing rectal cancer care. METHOD: Data for all patients undergoing rectal resection for clinical tumour node metastasis (TNM) stage I-III rectal cancer were extracted from the Swedish ColoRectal Cancer Registry and the Dutch ColoRectal Audit (2011-2015). Separate analyses were performed for cT1-3 and cT4 stage. Predictive factors for the CRM were determined using univariable and multivariable logistic regression analyses. RESULTS: A total of 6444 Swedish and 12 089 Dutch patients were analysed. Over time the number of hospitals treating rectal cancer decreased from 52 to 42 in Sweden, and 82 to 79 in the Netherlands. In the Swedish population, proportions of cT4 stage (17% vs 8%), multivisceral resection (14% vs 7%) and abdominoperineal excision (APR) (37% vs 31%) were higher. The overall proportion of patients with a positive CRM (CRM+) was 7.8% in Sweden and 5.4% in the Netherlands. In both populations with cT1-3 stage disease, common independent risk factors for CRM+ were cT3, APR and multivisceral resection. No common risk factors for CRM+ in cT4 stage disease were found. An independent impact of hospital volume on CRM+ could be demonstrated for the cT1-3 Dutch population. CONCLUSION: Within two northern European countries with implemented clinical auditing, rectal cancer care might potentially be improved by further optimizing the treatment of distal and locally advanced rectal cancer.

ABSTRACT

BACKGROUND: Routine colonoscopy was traditionally recommended after acute diverticulitis to exclude coexistent malignancy. Improved CT imaging may make routine colonoscopy less required over time but most guidelines still recommend it. The aim of this review was to assess the role of colonoscopy in patients with CT-proven acute diverticulitis. METHODS: PubMed and Embase were searched for studies reporting the prevalence of advanced colorectal neoplasia (ACN) or colorectal carcinoma in patients who underwent colonoscopy within 1 year after CT-proven left-sided acute diverticulitis. The prevalence was pooled using a random-effects model and, if possible, compared with that among asymptomatic controls. RESULTS: Seventeen studies with 3296 patients were included. The pooled prevalence of ACN was 6·9 (95 per cent c.i. 5·0 to 9·4) per cent and that of colorectal carcinoma was 2·1 (1·5 to 3·1) per cent. Only two studies reported a comparison with asymptomatic controls, showing comparable risks (risk ratio 1·80, 95 per cent c.i. 0·66 to 4·96). In subgroup analysis of patients with uncomplicated acute diverticulitis, the prevalence of colorectal carcinoma was only 0·5 (0·2 to 1·2) per cent. CONCLUSION: Routine colonoscopy may be omitted in patients with uncomplicated diverticulitis if CT imaging is otherwise clear. Patients with complicated disease or ongoing symptoms should undergo colonoscopy.

ABSTRACT

PURPOSE: To determine the incidence rate and identify predictive factors for interval appendectomy after non-operatively treated complicated appendicitis. METHODS: Single-center retrospective cohort study conducted between January 2008 and June 2017. Adult patients with acute appendicitis were identified. Patients with complicated appendicitis initially treated non-operatively were included. Outcomes included abscess rate on imaging, results of additional imaging during follow-up, incidence rate of and surgical indications for interval appendectomy, and outcomes of histological reports. RESULTS: Of all adult patients with acute appendicitis (n = 1839), 9% (170/1839) was initially treated non-operatively. Median age of these patients was 55 years (IQR 42-65) and 48.8% (83/170) were men. In 36.4% (62/170) of the patients, an appendicular abscess was diagnosed. 62.4% (106/170) did not require subsequent surgery (no interval appendectomy group) and in 37.6% (64/170), an interval appendectomy was performed (interval appendectomy group). Median follow-up was 80 weeks (17-192) and 113 weeks (34-246), respectively. Most frequent reason to perform subsequent surgery was recurrent appendicitis (45% (29/64)). Increasing age was significantly associated with a lower risk of undergoing interval appendectomy (OR 0.7; CI 0.6-0.89); p = 0.002). In the interval appendectomy group, appendicular neoplasm was found in 11% (7/64) of the patients, in contrast to 1.5% (25/1669) of the patients that had acute surgery (p < 0.001). CONCLUSIONS: One out of three patients non-operatively treated for complicated appendicitis required an interval appendectomy. The incidence of appendicular neoplasms was high in these patients compared with those that had acute surgery. Therefore, additional radiological imaging following non-operatively treated complicated appendicitis is recommended.

ABSTRACT

PURPOSE: The underling pathophysiological mechanisms that cause the formation of colonic diverticula (diverticulosis) remain unclear. Connective tissue changes due to ageing that cause changes in collagen structure of the colonic wall is one theory. Alpha-1-antitrypsin (A1AT) is a protease inhibitor known to protect connective tissue in other organs. Associations between (carriers of) A1AT deficiency and the development of colonic diverticula will be the main focus of this study. METHODS: A multicentre prospective case-controlled study. In total, 230 patients ≥ 60 years with acute abdominal pain undergoing an abdominal computed tomography (CT) will be included. The research group consists of patients with diverticulosis and/or diverticulitis; controls are patients without diverticula (0 to ≤ 5 diverticula). Genotype analysis for A1AT deficiency will be performed. RATIONALE: Hypothetically, connective tissue changes, in particular related to (carriers of) A1AT deficiency, can contribute to the development of diverticula and diverticulitis. We expect to find a higher prevalence of A1AT carriers in patients with diverticulosis compared to patients without diverticulosis. Having diverticulosis does not affect the general health of these individuals per se, when asymptomatic. Once an association is found, present findings can be the basis for a second study to assess the risk of developing acute diverticulitis and its disease course in carriers of A1AT deficiency. Because a large cohort is needed in the latter, we shall first perform a pilot study to investigate the likelihood of the primary hypothesis.

ABSTRACT

BACKGROUND: The shift from routine antibiotics towards omitting antibiotics for uncomplicated acute diverticulitis opens up the possibility for outpatient instead of inpatient treatment, potentially reducing the burden of one of the most common gastrointestinal diseases in the Western world. PURPOSE: Assessing the safety and cost savings of outpatient treatment in acute colonic diverticulitis. METHODS: PubMed and EMBASE were searched for studies on outpatient treatment of colonic diverticulitis, confirmed with computed tomography or ultrasound. Outcomes were readmission rate, need for emergency surgery or percutaneous abscess drainage, and healthcare costs. RESULTS: A total of 19 studies with 2303 outpatient treated patients were included. These studies predominantly excluded patients with comorbidity or immunosuppression, inability to tolerate oral intake, or lack of an adequate social network. The pooled incidence rate of readmission for outpatient treatment was 7% (95%CI 6-9%, I2 48%). Only 0.2% (2/1288) of patients underwent emergency surgery, and 0.2% (2/1082) of patients underwent percutaneous abscess drainage. Only two studies compared readmission rates outpatients that had similar characteristics as a control group of inpatients; 4.5% (3/66) and 6.3% (2/32) readmissions in outpatient groups versus 6.1% (4/66) and 0.0% (0/44) readmissions in inpatient groups (p = 0.619 and p = 0.174, respectively). Average healthcare cost savings for outpatient compared with inpatient treatment ranged between 42 and 82%. CONCLUSION: Outpatient treatment of uncomplicated diverticulitis resulted in low readmission rates and very low rates of complications. Furthermore, healthcare cost savings were substantial. Therefore, outpatient treatment of uncomplicated diverticulitis seems to be a safe option for most patients.

ABSTRACT

BACKGROUND: Ileostomy construction is a common procedure but can be associated with morbidity. The stoma is commonly secured to the skin using transcutaneous sutures. It is hypothesized that intracutaneous sutures result in a tighter adherence of the peristomal skin to the stoma plate to prevent faecal leakage. The study aimed to compare the effect of intracutaneous versus transcutaneous suturing of ileostomies on faecal leakage and quality of life. METHODS: This randomized trial was undertaken in 11 hospitals in the Netherlands. Patients scheduled to receive an ileostomy for any reason were randomized to intracutaneous or transcutaneous suturing (IC and TC groups respectively). The primary outcome was faecal leakage. Secondary outcomes were stoma-related quality of life and costs of stoma-related materials and reinterventions. RESULTS: Between April 2011 and February 2016, 339 patients were randomized to the IC (170) or TC (169) group. Leakage rates were higher in the IC than in the TC group (52·4 versus 41·4 per cent respectively; risk difference 11·0 (95 per cent c.i. 0·3 to 21·2) per cent). Skin irritation rates were high (78·2 versus 72·2 per cent), but did not differ significantly between the groups (risk difference 6·1 (95 per cent c.i. -3·2 to 15·10) per cent). There were no significant differences in quality of life or costs between the groups. CONCLUSION: Intracutaneous suturing of an ileostomy is associated with more peristomal leakage than transcutaneous suturing. Overall stoma-related complications did not differ between the two techniques. Registration number: NTR2369 ( http://www.trialregister.nl).

ABSTRACT

PURPOSE: A laparoscopic approach for emergency appendectomy is increasingly used, in pediatric patients as well. The objective of this study is to audit the current state of diagnostic work-up, surgical techniques and its outcome in children with acute appendicitis. METHODS: A prospective consecutive observational cohort study was carried out in a 2-month study period. All patients under 18 years that were operated for suspected acute appendicitis were included. Primary outcome was the infectious complication rate after open and laparoscopic approach; secondary outcomes were preoperative use of imaging and post-operative predictive value of imaging, normal appendix rate and children with a postoperative ileus. RESULTS: A total of 541 children were operated for suspected acute appendicitis in 62 Dutch hospitals. Preoperative imaging was used in 98.9% of children. The normal appendix rate was 3.1%. In 523 children an appendectomy was performed. Laparoscopy was used in 61% of the patients and conversion rate was 1.7%. Complicated appendicitis was diagnosed in 29.4% of children. Overall 30-day complication rate was 11.9% and similar after open and laparoscopic. No difference was found in superficial surgical site infections, nor in intra-abdominal abscesses between the open and laparoscopic approach. Complicated appendicitis is an independent risk factor for infectious complications. CONCLUSION: The laparoscopic approach is most frequently used, except for young children. Superficial surgical site infections are more frequent after open surgery only in patients with complicated appendicitis. The normal appendix rate is low, most likely because of routine preoperative imaging.

ABSTRACT

AIM: Low Hartmann's resection (LHR) and intersphincteric abdominoperineal excision (iAPR) are both feasible options in the treatment of rectal cancer when restoration of bowel continuity is not desired. The aim of this study was to compare the incidence of pelvic abscess and associated need for re-intervention and readmission after LHR and iAPR. METHOD: From a snapshot research project in which all rectal cancer resections from 71 Dutch hospitals in 2011 were evaluated, patients who underwent LHR or iAPR were selected. RESULTS: A total of 185 patients were included: 139 LHR and 46 iAPR. No differences in baseline characteristics were found except for more multivisceral resections in the iAPR group (22% vs 10%; P = 0.041). Pelvic abscesses were diagnosed in 17% of the LHR group after a median of 21 days (interquartile range 10-151 days), compared to 11% in the iAPR group (P = 0.352) after a median of 90 days (interquartile range 44-269 days; P = 0.102). All 28 patients with a pelvic abscess underwent at least one re-intervention. Four patients (9%) in the iAPR group and nine (7%) after LHR were readmitted because of a pelvic abscess over a median 39 months of follow-up. CONCLUSION: This cross-sectional multicentre study suggests that cross-stapling and intersphincteric resection of the rectal stump, during non-restorative rectal cancer resection, are associated with an equal risk of pelvic abscess formation and have a similar need for re-intervention and readmission.

ABSTRACT

AIM: The construction of a new coloanal anastomosis (CAA) following anastomotic leakage after low anterior resection (LAR) is challenging. The available literature on this topic is scarce. The aim of this two-centre study was to determine the clinical success and morbidity after redo CAA. METHOD: This retrospective cohort study included all patients with anastomotic leakage after LAR for rectal cancer who underwent a redo CAA between 2010 and 2014 in two tertiary referral centres. Short- and long-term morbidity were analysed, including both anastomotic leakage and permanent stoma rates on completion of follow-up. RESULTS: A total of 59 patients were included, of whom 45 (76%) were men, with a mean age of 59 years (SD ± 9.4). The median interval between index and redo surgery was 14 months [interquartile range (IQR) 8-27]. The median duration of follow-up was 27 months (IQR 17-36). The most frequent complication was anastomotic leakage of the redo CAA occurring in 24 patients (41%), resulting in a median of three reinterventions (IQR 2-4) per patient. At the end of follow-up, bowel continuity was restored in 39/59 (66%) patients. Fourteen (24%) patients received a definitive colostomy and six (10%) still had a diverting ileostomy. In a multivariable model, leakage of the redo CAA was the only risk factor for permanent stoma (OR 0.022; 95% CI 0.004-0.122). CONCLUSION: Redo CAA is a viable option in selected patients with persisting leakage after LAR for rectal cancer who want their bowel continuity restored. However, patients should be fully informed about the relatively high morbidity and reintervention rates.

ABSTRACT

PURPOSE: Since outpatient treatment and omitting antibiotics for uncomplicated acute colonic diverticulitis have been proven to be safe in the majority of patients, selection of patients that may not be suited for this treatment strategy becomes an important topic. The aim of this study is to identify computed tomography (CT) imaging predictors for a complicated disease course of initially uncomplicated acute diverticulitis. METHODS: CT imaging from a randomized controlled trial (DIABOLO study) of an observational vs. antibiotic treatment strategy of first-episode uncomplicated acute diverticulitis patients was re-evaluated. For each patient that developed complicated diverticulitis within 90 days after randomization, two patients with an uncomplicated disease course were randomly selected. Two abdominal radiologists, blinded for outcomes, independently re-evaluated all CTs. RESULTS: Of the 528 patients in the DIABOLO trial, 16 patients developed complications (abscess > 5 cm, perforation, bowel obstruction) within 90 days after randomization. In the group with a complicated course of initially uncomplicated diverticulitis, more patients with fluid collections (25 vs. 0%; p = 0.009) and a longer inflamed colon segment (86 ± 26 mm vs. 65 ± 21 mm; p = 0.007) were observed compared to an uncomplicated course of disease. Pericolic extraluminal air was no predictive factor. CONCLUSION: Fluid collections and to a lesser extent the length of the inflamed colon segment may serve as predictive factors on initial CT for a complicated disease course in patients with uncomplicated acute colonic diverticulitis. These findings may aid in the selection of patients not suitable for outpatient treatment and treatment without antibiotics.

ABSTRACT

PURPOSE OF REVIEW: Since the treatment of acute diverticulitis has become more conservative over the last years, knowledge of conservative treatment strategies is increasingly important. RECENT FINDINGS: Several treatment strategies that previously have been imposed as routine treatment are now obsolete. Uncomplicated diverticulitis patients can be treated without antibiotics, without bed rest, and without dietary restrictions; and a selected group of patients can be treated as outpatients. Also, patients with isolated pericolic extraluminal air can be treated conservatively as well. Whereas some patient subgroups have been suggested to suffer from a more virulent disease course or higher recurrence rates, current evidence does not support all traditional understandings. Patients on immunosuppression or non-steroidal anti-inflammatory drugs seem to have a higher risk of complicated diverticulitis, but young patients do not. Data on the risk of recurrent diverticulitis in young patients is conflicting but the risk seems comparable to elderly patients. Besides the traditional treatments, several new treatment strategies have emerged but have failed thus far. Mesalazine does not have any beneficial effect on preventing recurrent diverticulitis based on current literature. Rifaximin and probiotics have been studied insufficiently in acute diverticulitis patients to conclude on their efficacy. This review provides an overview of recent developments in conservative treatment strategies of acute diverticulitis and discusses the latest evidence on patient subgroups that have been suggested to suffer from an aberrant disease course.

ABSTRACT

BACKGROUND: Many patients who have surgery for acute cholecystitis receive postoperative antibiotic prophylaxis, with the intent to reduce infectious complications. There is, however, no evidence that extending antibiotics beyond a single perioperative dose is advantageous. This study aimed to determine the effect of extended antibiotic prophylaxis on infectious complications in patients with mild acute cholecystitis undergoing cholecystectomy. METHODS: For this randomized controlled non-inferiority trial, adult patients with mild acute calculous cholecystitis undergoing cholecystectomy at six major teaching hospitals in the Netherlands, between April 2012 and September 2014, were assessed for eligibility. Patients were randomized to either a single preoperative dose of cefazolin (2000 mg), or antibiotic prophylaxis for 3 days after surgery (intravenous cefuroxime 750 mg plus metronidazole 500 mg, three times daily), in addition to the single dose. The primary endpoint was rate of infectious complications within 30 days after operation. RESULTS: In the intention-to-treat analysis, three of 77 patients (4 per cent) in the extended antibiotic group and three of 73 (4 per cent) in the standard prophylaxis group developed postoperative infectious complications (absolute difference 0·2 (95 per cent c.i. -8·2 to 8·9) per cent). Based on a margin of 5 per cent, non-inferiority of standard prophylaxis compared with extended prophylaxis was not proven. Median length of hospital stay was 3 days in the extended antibiotic group and 1 day in the standard prophylaxis group. CONCLUSION: Standard single-dose antibiotic prophylaxis did not lead to an increase in postoperative infectious complications in patients with mild acute cholecystitis undergoing cholecystectomy.
