Summary
In the peri‐operative period, dexamethasone is widely and effectively used for prophylaxis of postoperative nausea and vomiting. The objective of this meta‐analysis was to assess the adverse ...effects of an incidental steroid load of dexamethasone in adult surgical patients. We searched in MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and the Web of Science for randomised controlled trials comparing an incidental steroid load of dexamethasone with a control intervention in adult patients undergoing surgery. Two review authors independently screened studies for eligibility, extracted data and assessed all included studies for bias. Our primary outcomes were postoperative systemic or wound infection, delayed wound healing and glycaemic response within 24 h. We included 37 studies in this meta‐analysis. The pooled results found no evidence that dexamethasone increased the risk of a postoperative wound infection, Peto OR (95%CI) 1.01 (0.80–1.27); 4603 participants, 26 studies; I² = 32%; moderate‐quality evidence. Whether dexamethasone influenced wound healing was unclear due to the large confidence intervals, Peto OR (95%CI) 0.99 (0.28–3.43); 1072 participants, 8 studies; I² = 0%; low‐quality evidence. Dexamethasone produced a mild increase in glucose levels among participants without diabetes during the first 12 h after surgery, mean difference (95%CI) 0.7 mmol.l−1(0.3–1.2) 10 studies; 595 participants; I² = 50%; low‐quality evidence. This article is an abridged version of a Cochrane Review.

Abstract
Background
Adequate MRI-based staging of early rectal cancers is essential for decision-making in an era of organ-conserving treatment approaches. The aim of this population-based study was ...to determine the accuracy of routine daily MRI staging of early rectal cancer, whether or not combined with endorectal ultrasonography (ERUS).
Methods
Patients with cT1–2 rectal cancer who underwent local excision or total mesorectal excision (TME) without downsizing (chemo)radiotherapy between 1 January 2011 and 31 December 2018 were selected from the Dutch ColoRectal Audit. The accuracy of imaging was expressed as sensitivity, specificity, and positive predictive value (PPV) and negative predictive value.
Results
Of 7382 registered patients with cT1–2 rectal cancer, 5539 were included (5288 MRI alone, 251 MRI and ERUS; 1059 cT1 and 4480 cT2). Among patients with pT1 tumours, 54·7 per cent (792 of 1448) were overstaged by MRI alone, and 31·0 per cent (36 of 116) by MRI and ERUS. Understaging of pT2 disease occurred in 8·2 per cent (197 of 2388) and 27·9 per cent (31 of 111) respectively. MRI alone overstaged pN0 in 17·3 per cent (570 of 3303) and the PPV for assignment of cN0 category was 76·3 per cent (2733 of 3583). Of 834 patients with pT1 N0 disease, potentially suitable for local excision, tumours in 253 patients (30·3 per cent) were staged correctly as cT1 N0, whereas 484 (58·0 per cent) and 97 (11·6 per cent) were overstaged as cT2 N0 and cT1–2 N1 respectively.
Conclusion
This Dutch population-based analysis of patients who underwent local excision or TME surgery for cT1–2 rectal cancer based on preoperative MRI staging revealed substantial overstaging, indicating the weaknesses of MRI and missed opportunities for organ preservation strategies.
Graphical Abstract
This population-based study determined the accuracy of routine daily MRI staging of early rectal cancer, whether or not combined with endorectal ultrasonography. The results showed that preoperative MRI led to substantial overstaging in patients who underwent local excision or total mesorectal incision surgery for cT1–2 rectal cancer, indicating the weaknesses of MRI and missed opportunities for organ preservation strategies.

Background
Antibiotics are advised in most guidelines on acute diverticulitis, despite a lack of evidence to support their routine use. This trial compared the effectiveness of a strategy with or ...without antibiotics for a first episode of uncomplicated acute diverticulitis.
Methods
Patients with CT‐proven, primary, left‐sided, uncomplicated, acute diverticulitis were included at 22 clinical sites in the Netherlands, and assigned randomly to an observational or antibiotic treatment strategy. The primary endpoint was time to recovery during 6 months of follow‐up. Main secondary endpoints were readmission rate, complicated, ongoing and recurrent diverticulitis, sigmoid resection and mortality. Intention‐to‐treat and per‐protocol analyses were done.
Results
A total of 528 patients were included. Median time to recovery was 14 (i.q.r. 6–35) days for the observational and 12 (7–30) days for the antibiotic treatment strategy, with a hazard ratio for recovery of 0·91 (lower limit of 1‐sided 95 per cent c.i. 0·78; P = 0·151). No significant differences between the observation and antibiotic treatment groups were found for secondary endpoints: complicated diverticulitis (3·8 versus 2·6 per cent respectively; P = 0·377), ongoing diverticulitis (7·3 versus 4·1 per cent; P = 0·183), recurrent diverticulitis (3·4 versus 3·0 per cent; P = 0·494), sigmoid resection (3·8 versus 2·3 per cent; P = 0·323), readmission (17·6 versus 12·0 per cent; P = 0·148), adverse events (48·5 versus 54·5 per cent; P = 0·221) and mortality (1·1 versus 0·4 per cent; P = 0·432). Hospital stay was significantly shorter in the observation group (2 versus 3 days; P = 0·006). Per‐protocol analyses were concordant with the intention‐to‐treat analyses.
Conclusion
Observational treatment without antibiotics did not prolong recovery and can be considered appropriate in patients with uncomplicated diverticulitis. Registration number: NCT01111253 (http://www.clinicaltrials.gov).

Background
Several studies have been published favouring sigmoidectomy with primary anastomosis over Hartmann's procedure for perforated diverticulitis with purulent or faecal peritonitis (Hinchey ...grade III or IV), but cost‐related outcomes were rarely reported. The present study aimed to evaluate costs and cost‐effectiveness within the DIVA arm of the Ladies trial.
Methods
This was a cost‐effectiveness analysis of the DIVA arm of the multicentre randomized Ladies trial, comparing primary anastomosis over Hartmann's procedure for Hinchey grade III or IV diverticulitis. During 12‐month follow‐up, data on resource use, indirect costs (Short Form Health and Labour Questionnaire) and quality of life (EuroQol Five Dimensions) were collected prospectively, and analysed according to the modified intention‐to‐treat principle. Main outcomes were incremental cost‐effectiveness (ICER) and cost–utility (ICUR) ratios, expressed as the ratio of incremental costs and the incremental probability of being stoma‐free or incremental quality‐adjusted life‐years respectively.
Results
Overall, 130 patients were included, of whom 64 were allocated to primary anastomosis (46 and 18 with Hinchey III and IV disease respectively) and 66 to Hartmann's procedure (46 and 20 respectively). Overall mean costs per patient were lower for primary anastomosis (€20 544, 95 per cent c.i. 19 569 to 21 519) than Hartmann's procedure (€28 670, 26 636 to 30 704), with a mean difference of €–8126 (–14 660 to –1592). The ICER was €–39 094 (95 per cent bias‐corrected and accelerated (BCa) c.i. –1213 to –116), indicating primary anastomosis to be more cost‐effective. The ICUR was €–101 435 (BCa c.i. –1 113 264 to 251 840).
Conclusion
Primary anastomosis is more cost‐effective than Hartmann's procedure for perforated diverticulitis with purulent or faecal peritonitis.
Antecedentes
Se han publicado varios estudios en favor de la sigmoidectomía con anastomosis primaria (primary anastomosis, PA) sobre la intervención de Hartmann (Hartmann’s procedure, HP) para la diverticulitis perforada con peritonitis purulenta o fecal (Hinchey grado III ó IV), pero apenas existe información de los resultados relacionados con el coste. Por lo tanto, el presente estudio tuvo como objetivo evaluar los costes y el coste efectividad del brazo DIVA en el ensayo clínico Ladies.
Métodos
Se realizó un análisis de coste‐efectividad del brazo DIVA del ensayo clínico multicéntrico y aleatorizado Ladies, que comparó PA y HP para la diverticulitis Hinchey de grado III ó IV. Durante un seguimiento de 12 meses, se recogieron datos prospectivamente del uso de recursos, costes indirectos (SF‐HLQ) y calidad de vida (EQ‐5D), y se analizaron de acuerdo con una modificación del principio por intención de tratar. Los resultados principales fueron la relación coste‐efectividad incremental (incremental cost‐effectiveness ratio, ICER) y la relación coste‐utilidad incremental (incremental cost‐utility ratio, ICUR), expresados como la razón del incremento de costes y el incremento en la probabilidad de no requerir estoma o años de vida ajustados por calidad, respectivamente.
Resultados
En total, se incluyeron 130 pacientes, 64 de los cuales fueron asignados a PA (Hinchey III/IV: 46/20) y 66 a HP (Hinchey III/IV: 46/18). Los costes medios globales por paciente fueron más bajos para la PA (€20.544 (i.c. del 95%: 19.569 a 21.519)) en comparación con HP (€ 28.670 (i.c. del 95%: 26.636 a 30.704)), con una diferencia media de €−8.126 (i.c. del 95% −14.660 a −1.592)). Además, se observó un ICER de € −39.094 (95% bias‐corrected and accelerated boodstrap confidence interval, BCaCI −1.213 a −116), lo que indica que PA es más coste efectiva. El ICUR fue € −101.435 (BCaCI del 95%: −1.113.264 a 251.840).
Conclusión
La anastomosis primaria es más rentable que el procedimiento de Hartmann para la diverticulitis perforada con peritonitis purulenta o fecal.
A cost‐effectiveness analysis of Hartmann's procedure versus primary anastomosis (with or without ileostomy) for patients with purulent or faecal peritonitis was conducted within the DIVA arm of the multicentre randomized Ladies trial. Primary anastomosis was found to be more cost‐effective than Hartmann's procedure and was associated with significantly lower overall mean costs per patient.

Background
Routine histopathological examination after cholecystectomy is costly, but the prevalence of unsuspected gallbladder cancer (incidental GBC) is low. This study determined whether selective ...histopathological examination is safe.
Methods
A comprehensive search of PubMed, Embase, Web of Science and the Cochrane Library was performed. Pooled incidences of incidental and truly incidental GBC (GBC detected during histopathological examination without preoperative or intraoperative suspicion) were estimated using a random‐effects model. The clinical consequences of truly incidental GBC were assessed.
Results
Seventy‐three studies (232 155 patients) were included. In low‐incidence countries, the pooled incidence was 0·32 (95 per cent c.i. 0·25 to 0·42) per cent for incidental GBC and 0·18 (0·10 to 0·35) per cent for truly incidental GBC. Subgroup analysis of studies in which surgeons systematically examined the gallbladder revealed a pooled incidence of 0·04 (0·01 to 0·14) per cent. In high‐incidence countries, corresponding pooled incidences were 0·83 (0·58 to 1·18), 0·44 (0·21 to 0·91) and 0·08 (0·02 to 0·39) per cent respectively. Clinical consequences were reported for 176 (39·3 per cent) of 448 patients with truly incidental GBC. Thirty‐three patients (18·8 per cent) underwent secondary surgery. Subgroup analysis showed that at least half of GBC not detected during the surgeon's systematic examination of the gallbladder was early stage (T1a status or below) and of no clinical consequence.
Conclusion
Selective histopathological examination of the gallbladder after initial macroscopic assessment by the surgeon seems safe and could reduce costs.
Antecedentes
El examen histopatológico rutinario después de la colecistectomía es caro y la prevalencia de cáncer de vesícula biliar (gallbladder cancer, GBC) no sospechado o incidental es baja. Este estudio determinó si el examen histológico selectivo es seguro.
Métodos
Se realizó una búsqueda exhaustiva en PubMed, Embase, Web of Science y en la Biblioteca Cochrane. Se estimaron las incidencias agrupadas de GBC incidental y realmente incidental (GBC detectado durante el examen histopatológico sin sospecha previa o intraoperatoria) utilizando un modelo de efectos aleatorios. Además, se evaluaron las consecuencias clínicas del GBC realmente incidental.
Resultados
Se incluyeron 73 estudios (n = 232.155). En los países de baja incidencia, la incidencia agrupada fue de 0,32% para el GBC incidental (i.c. del 95% 0,25 a 0,42) y de 0,18% (0,10 a 0,35) para GBC realmente incidental. El análisis de subgrupos que incluye estudios en los que los cirujanos examinaron sistemáticamente la vesícula biliar reveló una incidencia agrupada de 0,04% (0,01 a 0,14). En los países de alta incidencia, las incidencias agrupadas correspondientes fueron 0,83% (0,58 a 1,18), 0,44% (0.2 a 0.91) y 0,08% (0,02 a 0,39), respectivamente. Se describieron consecuencias clínicas en 176 (39,3%) de 448 pacientes con GBC realmente incidental. Treinta y tres pacientes (18,6%) se sometieron a cirugía secundaria. El análisis por subgrupos mostró que al menos la mitad de los GBC no detectados durante el examen sistemático de la vesícula biliar por parte del cirujano eran tumores de estadio precoz (≤ T1a) y sin consecuencias clínicas.
Conclusión
El examen histológico selectivo de vesículas biliares después de la evaluación macroscópica inicial realizada por el cirujano parece seguro y podría reducir los costes.
This meta‐analysis found that the incidence of truly incidental gallbladder cancer (GBC) was less than 0·5 per cent and decreased to less than 0·1 per cent when the surgeon performed a systematic macroscopic examination. At least 50 per cent of GBC that was not detected before or during surgery was of early stage and with no clinical consequences. Particularly in non‐endemic regions, selective histopathological examination after initital macroscopic assessment of the gallbladder by the surgeon seems safe and will likely result in significant cost and time savings.

Traditionally uncomplicated acute diverticulitis was routinely treated with antibiotics, although evidence for this strategy was lacking. Recently, two randomized clinical trials (AVOD trial and ...DIABOLO trial) published short-term results of omitting antibiotics compared to routine antibiotic treatment. Both showed no significant differences regarding recovery from the initial episode, as well as rates of complicated or recurrent diverticulitis and sigmoid resection. However, both studies showed a trend of higher rates of sigmoid resection in the observational groups. Here, the long-term effects of omitting antibiotics in first episode uncomplicated acute diverticulitis were assessed.
A total of 528 patients with CT-proven, primary, left-sided, uncomplicated acute diverticulitis were randomized to either an observational or an antibiotic treatment strategy (DIABOLO trial). Outcome measures were complicated diverticulitis, recurrent diverticulitis and sigmoid resection at 24 months' follow up. Differences between the groups were explored and risk factors were identified using multivariable logistic regression.
Complete case analyses showed no difference in rates of recurrent diverticulitis (15.4% in the observational group versus 14.9% in the antibiotic group; p = 0.885), complicated diverticulitis (4.8% versus 3.3%; p = 0.403) and sigmoid resection (9.0% versus. 5.0%; p = 0.085). Young patients (<50 years) and patients with a pain score at presentation of 8 or higher on a visual analogue pain scale were at risk for complicated or recurrent diverticulitis. In this multivariable analysis, treatment type (with or without antibiotics) was not an independent predictor for complicated or recurrent diverticulitis.
Omitting antibiotics in the treatment of uncomplicated acute diverticulitis did not result in more complicated diverticulitis, recurrent diverticulitis or sigmoid resections at long-term follow up. As the DIABOLO trial was not powered for these secondary outcome measures, some uncertainty remains whether (small) non-significant differences could be true associations.
Introduction
Non-healing of anastomotic leakage can be observed in up to 50% after total mesorectal excision for rectal cancer. This study investigates the efficacy of early transanal closure of ...anastomotic leakage after pre-treatment with the Endosponge
®
therapy.
Methods
In this prospective, multicentre, feasibility study, transanal suturing of the anastomotic defect was performed after vacuum-assisted cleaning of the presacral cavity. Primary outcome was the proportion of patients with a healed anastomosis at 6 months after transanal closure. Secondary, healing at last follow-up, continuity, direct medical costs, functionality and quality of life were analysed.
Results
Between July 2013 and July 2015, 30 rectal cancer patients with a leaking low colorectal anastomosis were included, of whom 22 underwent neoadjuvant radiotherapy. Median follow-up was 14 (7–29) months. At 6 months, the anastomosis had healed in 16 (53%) patients. At last follow-up, anastomotic integrity was found in 21 (70%) and continuity was restored in 20 (67%) patients. Non-healing at 12 months was observed in 10/29 (34%) patients overall, and in 3/14 (21%) when therapy started within three weeks following the index operation. Major LARS was reported in 12/15 (80%) patients. The direct medical costs were €8933 (95% CI 7268–10,707) per patient.
Conclusion
Vacuum-assisted early transanal closure of a leaking anastomosis after total mesorectal excision with 73% preoperative radiotherapy showed that acceptable anastomotic healing rates and stoma reversal rates can be achieved. Early diagnosis and start of treatment seems crucial.

Studies on postoperative complications and survival in patients with pancreatic neuroendocrine tumors (pNET) are sparse and randomized controlled trials are not available. We reviewed all studies on ...postoperative complications and survival after resection of pNET. A systematic search was performed in the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE from 2000–2013. Inclusion criteria were studies of resected pNET, which described postoperative complications separately for each surgical procedure and/or 5-year survival after resection. Prospective and retrospective studies were pooled separately and overall pooled if heterogeneity was below 75 %. The random-effect model was used. Overall, 2643 studies were identified and after full-text analysis 62 studies were included. Pancreatic fistula (PF) rate of the prospective studies after tumor enucleation was 45 %; PF-rates after distal pancreatectomy, pancreatoduodenectomy, or central pancreatectomy were, respectively, 14–14–58 %. Delayed gastric emptying rates were, respectively, 5–5–18–16 %. Postoperative hemorrhage rates were, respectively, 6–1–7–4 %. In-hospital mortality rates were, respectively, 3–4–6–4 %. The 5-year overall survival (OS) and disease-specific survival (DSS) of resected pNET without synchronous resected liver metastases were, respectively, 85–93 %. Heterogeneity between included studies on 5-year OS in patients with synchronous resected liver metastases was too high to pool all studies. The 5-year DSS in patients with liver metastases was 80 %. Morbidity after pancreatic resection for pNET was mainly caused by PF. Liver resection in patients with liver metastases seems to have a positive effect on DSS. To reduce heterogeneity, ISGPS criteria and uniform patient groups should be used in the analysis of postoperative outcome and survival.

Background
Surgical safety may be improved using a medical data recorder (MDR) for the purpose of postoperative team debriefing. It provides the team in the operating room (OR) with the opportunity ...to look back upon their joint performance objectively to discuss and learn from suboptimal situations or possible adverse events. The aim of this study was to investigate the satisfaction of the OR team using an MDR, the OR Black Box®, in the OR as a tool providing output for structured team debriefing.
Methods
In this longitudinal survey study, 35 gastro-intestinal laparoscopic operations were recorded using the OR Black Box® and the output was subsequently debriefed with the operating team. Prior to study, a privacy impact assessment was conducted to ensure alignment with applicable legal and regulatory requirements. A structured debrief model and an OR Back Box® performance report was developed. A standardized survey was used to measure participant’s satisfaction with the team debriefing, the debrief model used and the performance report. Factor analysis was performed to assess the questionnaire’s quality and identified contributing satisfaction factors. Multivariable analysis was performed to identify variables associated with participants’ opinions.
Results
In total, 81 team members of various disciplines in the OR participated, comprising 35 laparoscopic procedures. Mean satisfaction with the OR Black Box® performance report and team debriefing was high for all 3 identified independent satisfaction factors. Of all participants, 98% recommend using the OR Black Box® and the outcome report in team debriefing.
Conclusion
The use of an MDR in the OR for the purpose of team debriefing is considered to be both beneficial and important. Team debriefing using the OR Black Box® outcome report is highly recommended by 98% of team members participating.

Aim
Although has been suggested that an appendectomy has a positive effect on the disease course in patients with ulcerative colitis (UC), recent studies indicate a potential increase in risk of ...colectomy and colorectal cancer (CRC). This study aimed to evaluate the rates of colectomy and CRC after appendectomy in UC patients using a nationwide prospective database the Initiative on Crohn and Colitis Parelsnoer Institute – Inflammatory Bowel Disease (ICC PSI‐IBD) database.
Method
All UC patients were retrieved from the ICC PSI‐IBD database between January 2007 and May 2018. Primary outcomes were colectomy and CRC. Outcomes were compared in patients with and without appendectomy, with a separate analysis for timing of appendectomy (before or after UC diagnosis).
Results
A total of 826 UC patients (54.7% female; median age 46 years, range 18–89 years) were included. Sixty‐three (7.6%) patients had previously undergone appendectomy: 24 (38.1%) before and 33 (52.4%) after their diagnosis of UC. In multivariate analysis, appendectomy after UC diagnosis was associated with a significantly lower colectomy rate compared with no appendectomy hazard ratio (HR) 0.16, 95% C: 0.04–0.66, P = 0.011, and the same nonsignificant trend was seen in patients with an appendectomy before UC diagnosis (HR 0.35, 95% CI 0.08–1.41, P = 0.138). Appendectomy was associated with delayed colectomy, particularly when it was performed after diagnosis of UC (P = 0.009). No significant differences were found in the CRC rate between patients with and without appendectomy (1.6% vs 1.2%; P = 0.555).
Conclusion
Appendectomy in established UC is associated with an 84% decreased risk of colectomy and a delay in surgery. Since the colon is in situ for longer, the risk of developing CRC remains, which underscores the importance of endoscopic surveillance programmes.
