RESUMO
BACKGROUND: It has previously been reported that there are similar reoperation rates after elective colorectal surgery but higher failure-to-rescue (FTR) rates in low-volume hospitals (LVHs) versus high-volume hospitals (HVHs). This study assessed the effect of hospital volume on reoperation rate and FTR after reoperation following elective colorectal surgery in a matched cohort. METHODS: Population-based retrospective multicentre cohort study of adult patients undergoing reoperation for a complication after an elective, non-centralized colorectal operation between 2006 and 2017 in 11 hospitals. Hospitals were divided into either HVHs (3 hospitals, median ≥126 resections per year) or LVHs (8 hospitals, <126 resections per year). Patients were propensity score-matched (PSM) for baseline characteristics as well as indication and type of elective surgery. Primary outcome was FTR. RESULTS: A total of 6428 and 3020 elective colorectal resections were carried out in HVHs and LVHs, of which 217 (3.4%) and 165 (5.5%) underwent reoperation (P < 0.001), respectively. After PSM, 142 patients undergoing reoperation remained in both HVH and LVH groups for final analyses. FTR rate was 7.7% in HVHs and 10.6% in LVHs (P = 0.410). The median Comprehensive Complication Index was 21.8 in HVHs and 29.6 in LVHs (P = 0.045). There was no difference in median ICU-free days, length of stay, the risk for permanent ostomy or overall survival between the groups. CONCLUSION: The reoperation rate and postoperative complication burden was higher in LVHs with no significant difference in FTR compared with HVHs.

BACKGROUND AND AIMS: Long pre-hospital delay substantially increases the likelihood of perforated appendicitis. This study aimed to find patient-related factors affecting this delay. METHODS: A survey was conducted for patients with acute appendicitis after appendectomy. The participants were asked about their path to the surgical center and socioeconomic status. Variables affecting delays and the rate of complicated appendicitis were analyzed. RESULTS: The study included 510 patients; 157 (31%) had complicated appendicitis with a median prehospital delay of 42 h. In patients with uncomplicated appendicitis, the delay was 21 h, p < .001. Forty-six (29%) patients with complicated appendicitis were not referred to the hospital after the first doctor's visit. The multivariate analysis discovered factors associated with long pre-hospital delay: age 40-64 years (OR 1.63 (95% CI 1.06-2.52); compared to age 18-39), age more than 64 years (OR 2.84 (95% CI 1.18-6.80); compared to age 18-39), loss of appetite (OR 2.86 (95% CI 1.64-4.98)), fever (OR 1.66 (95% CI 1.08-2.57)), non-referral by helpline nurse (OR 2.02 (95% CI 1.15-3.53)) and non-referral at first doctors visit (OR 2.16 (95% CI 1.32-3.53)). Age 40-64 years (OR 2.41 (95% CI 1.50-3.88)), age more than 64 years (OR 8.79 (95% CI 2.19-35.36)), fever (OR 1.83 (95% CI 1.15-2.89)) and non-referral at first doctors visit (OR 1.90 (95% CI 1.14-3.14)) were also risk factors for complicated appendicitis. CONCLUSIONS: Advanced age, fever and failure to suspect acute appendicitis in primary care are associated with prolonged pre-hospital delay and complicated appendicitis.

BACKGROUND: Appendicitis is one of the most common pathologies encountered by general and acute care surgeons. The current literature is inconsistent, as it is fraught with outcome heterogeneity, especially in the area of nonoperative management. We sought to develop a core outcome set (COS) for future appendicitis studies to facilitate outcome standardization and future data pooling. METHODS: A modified Delphi study was conducted after identification of content experts in the field of appendicitis using both the Eastern Association for the Surgery of Trauma (EAST) landmark appendicitis articles and consensus from the EAST ad hoc COS taskforce on appendicitis. The study incorporated three rounds. Round 1 utilized free text outcome suggestions, then in rounds 2 and 3 the suggests were scored using a Likert scale of 1 to 9 with 1 to 3 denoting a less important outcome, 4 to 6 denoting an important but noncritical outcome, and 7 to 9 denoting a critically important outcome. Core outcome status consensus was defined a priori as >70% of scores 7 to 9 and <15% of scores 1 to 3. RESULTS: Seventeen panelists initially agreed to participate in the study with 16 completing the process (94%). Thirty-two unique potential outcomes were initially suggested in round 1 and 10 (31%) met consensus with one outcome meeting exclusion at the end of round 2. At completion of round 3, a total of 17 (53%) outcomes achieved COS consensus. CONCLUSION: An international panel of 16 appendicitis experts achieved consensus on 17 core outcomes that should be incorporated into future appendicitis studies as a minimum set of standardized outcomes to help frame future cohort-based studies on appendicitis. LEVEL OF EVIDENCE: Diagnostic Test or Criteria; Level V.

BACKGROUND: The open abdomen is an innovation that greatly improved surgical understanding of damage control, temporary abdominal closure, staged abdominal reconstruction, viscera and enteric fistula care, and abdominal wall reconstruction. This article provides an evidence-informed, expert, comprehensive narrative review of the open abdomen in trauma, acute care, and vascular and endovascular surgery. METHODS: A group of 12 international trauma, acute care, and vascular and endovascular surgery experts were invited to review current literature and important concepts surrounding the open abdomen. RESULTS: The open abdomen may be classified using validated systems developed by a working group in 2009 and modified by the World Society of the Abdominal Compartment Syndrome-The Abdominal Compartment Society in 2013. It may be indicated in major trauma, intra-abdominal sepsis, vascular surgical emergencies, and severe acute pancreatitis; to facilitate second look laparotomy or avoid or treat abdominal compartment syndrome; and when the abdominal wall cannot be safely closed. Temporary abdominal closure and staged abdominal reconstruction methods include a mesh/sheet, transabdominal wall dynamic fascial traction, negative pressure wound therapy, and hybrid negative pressure wound therapy and dynamic fascial traction. This last method likely has the highest primary fascial closure rates. Direct peritoneal resuscitation is currently an experimental strategy developed to improve primary fascial closure rates and reduce complications in those with an open abdomen. Primary fascial closure rates may be improved by early return to the operating room; limiting use of crystalloid fluids during the surgical interval; and preventing and/or treating intra-abdominal hypertension, enteric fistulae, and intra-abdominal collections after surgery. The majority of failures of primary fascial closure and enteroatmospheric fistula formation may be prevented using effective temporary abdominal closure techniques, providing appropriate resuscitation fluids and nutritional support, and closing the abdomen as early as possible. CONCLUSION: Subsequent stages of the innovation of the open abdomen will likely involve the design and conduct of prospective studies to evaluate appropriate indications for its use and effectiveness and safety of the above components of open abdomen management.

BACKGROUND: Appendicectomy remains the standard treatment for appendicitis. No international consensus exists on the surgical urgency for acute uncomplicated appendicitis, and recommendations vary from surgery without delay to surgery within 24 h. Longer in-hospital delay has been thought to increase the risk of perforation and further morbidity. Therefore, we aimed to compare the rate of appendiceal perforation in patients undergoing appendicectomy scheduled to two different urgencies (<8 h vs <24 h). METHODS: In this pragmatic, open-label, multicentre, non-inferiority, parallel, randomised controlled trial in two hospitals in Finland and one in Norway, patients (aged ≥18 years) with presumed uncomplicated acute appendicitis were randomly assigned (1:1) to an appendicectomy scheduled within 8 h or within 24 h to determine whether longer in-hospital delay (time between randomisation and surgical incision) is not inferior to shorter delay. Patients were excluded in cases of pregnancy, suspicion of perforated appendicitis (C-reactive protein level of ≥100 mg/L, fever >38·5°C, signs of complicated appendicitis on imaging studies, or clinical generalised peritonitis), or other reasons requiring prompt surgery. The recruiters were on-duty surgeons who decided to proceed with the appendicectomy. The randomisation sequence was generated using block randomisation with randomly varying block sizes and stratified by hospital districts; neither physicians nor patients were masked to group assignment. The primary outcome was perforated appendicitis diagnosed during surgery analysed in all patients who received an appendicectomy by intention to treat. The absolute difference in rates of perforated appendicitis was compared between the groups. Complications and other safety outcomes were analysed in all patients who received an appendicectomy. A margin of 5 percentage points was used to establish non-inferiority. This trial was registered at ClinicalTrials.gov (NCT04378868) and is closed to accrual. FINDINGS: Between May 18, 2020, and Dec 31, 2022, 2095 patients were assessed for eligibility, of whom 1822 were randomly assigned to appendicectomy scheduled within 8 h (n=914) or 24 h (n=908). After randomisation, 19 (1%) of 1822 patients were excluded due to protocol violation. 1803 patients were included in the intention-to-treat analyses, 985 (55%) of whom were male and 818 (45%) female. Appendiceal perforation rate was similar between groups (77 [8%] of 907 patients assigned to the <8 h group and 81 [9%] of 896 patients assigned to the <24 h group; absolute risk difference 0·6% [95% CI -2·1 to 3·2], p=0·68; risk ratio 1·065, 95% CI 0·790 to 1·435). No significant difference was found between the complication rates within 30 days (66 [7%] of 907 patients in the <8 h group vs 56 [6%] of 896 patients in the <24 h group; difference -1·0% [-3·3 to 1·3]; p=0·39), and no deaths occurred during this follow-up period. INTERPRETATION: In patients with presumed uncomplicated acute appendicitis, scheduling appendicectomy within 24 h does not increase the risk of appendiceal perforation compared with scheduling appendicectomy within 8 h. The results can be used to allocate operating room resources, for example postponing night-time appendicectomy to daytime. FUNDING: The Finnish Medical Foundation, Mary and Georg Ehrnrooth's Foundation, Biomedicum Helsinki Foundation, and the Finnish Government.

INTRODUCTION: A common feature of external duodenal fistulae is the devastating effect of the duodenal content rich in bile and pancreatic juice on nearby tissues with therapy-resistant local and systemic complications. This study analyzes the results of different management options with emphasis on successful fistula closure rates. METHODS: A retrospective single academic center study of adult patients treated for complex duodenal fistulas over a 17-year period with descriptive and univariate analyses was performed. RESULTS: Fifty patients were identified. First line treatment was surgical in 38 (76%) cases and consisted of resuture or resection with anastomosis combined with duodenal decompression and periduodenal drainage in 36 cases, rectus muscle patch, and surgical decompression with T-tube in one each. Fistula closure rate was 29/38 (76%). In 12 cases, the initial management was nonoperative with or without percutaneous drainage. The fistula was closed without surgery in 5/6 patients (1 patient died with persistent fistula). Among the remaining 6 patients eventually operated, fistula closure was achieved in 4 cases. There was no difference in successful fistula closure rates among initially operatively versus nonoperatively managed patients (29/38 vs. 9/12, p = 1.000). However, when considering eventually failed nonoperative management in 7/12 patients, there was a significant difference in the fistula closure rate (29/38 vs. 5/12, p = 0.036). The overall in-hospital mortality rate was 20/50 (40%). CONCLUSIONS: Surgical closure combined with duodenal decompression in complex duodenal leaks offers the best chance of successful outcome. In selected cases, nonoperative management can be tried, accepting that some patients may require surgery later.

Importance: Both elective sigmoid resection and conservative treatment are options for patients with recurrent, complicated, or persistent painful diverticulitis; understanding outcomes following each can help inform decision-making. Objective: To compare outcomes of elective sigmoid resection and conservative treatment for patients with recurrent, complicated, or persistent painful diverticulitis at 2-year follow-up. Design, Setting, and Participants: This multicenter parallel open-label individually randomized clinical trial comparing elective sigmoid resection to conservative treatment in patients with recurrent, complicated, or persistent painful diverticulitis was carried out in 5 Finnish hospitals between September 2014 and October 2018. Follow-up up to 2 years is reported. Of 85 patients randomized and included, 75 and 70 were available for QOL outcomes at 1 year and 2 years, respectively, and 79 and 78 were available for the recurrence outcome at 1 year and 2 years, respectively. The present analysis was conducted from September 2015 to June 2022. Interventions: Laparoscopic elective sigmoid resection vs conservative treatment (patient education and fiber supplementation). Main Outcomes and Measures: Prespecified secondary outcomes included Gastrointestinal Quality of Life Index (GIQLI) score, complications, and recurrences within 2 years. Results: Ninety patients (28 male [31%]; mean [SD] age, 54.11 [11.9] years and 62 female [69%]; mean [SD] age, 57.13 [7.6] years) were randomized either to elective sigmoid resection or conservative treatment. After exclusions, 41 patients in the surgery group and 44 in the conservative group were included in the intention-to-treat analyses. Eight patients (18%) in the conservative treatment group underwent sigmoid resection within 2 years. The mean GIQLI score at 1 year was 9.51 points higher in the surgery group compared to the conservative group (mean [SD], 118.54 [17.95] vs 109.03 [19.32]; 95% CI, 0.83-18.18; P = .03), while the mean GIQLI score at 2 years was similar between the groups. Within 2 years, 25 of 41 patients in the conservative group (61%) had recurrent diverticulitis compared to 4 of 37 patients in the surgery group (11%). Four of 41 patients in the surgery group (10%) and 2 of 44 in the conservative group (5%) had major postoperative complications within 2 years. In per-protocol analyses, the mean (SD) GIQLI score was higher in the surgery group compared to the conservative treatment group by 11.27 points at 12 months (119.42 [17.98] vs 108.15 [19.28]; 95% CI, 2.24-20.29; P = .02) and 10.43 points at 24 months (117.24 [15.51] vs 106.82 [18.94]; 95% CI, 1.52-19.33; P = .02). Conclusions and Relevance: In this randomized clinical trial, elective sigmoid resection was effective in preventing recurrent diverticulitis and improved quality of life over conservative treatment within 2 years. Trial Registration: ClinicalTrials.gov Identifier: NCT02174926.

BACKGROUND AND OBJECTIVE: Acute mesenteric ischemia (AMI) has a high mortality rate due to the development of bowel necrosis. Patients are often ruled outside active care if a large proportion of small bowel is necrotic. With the development of treatment for short bowel syndrome (SBS) and intestinal transplantation methods, long-term survival is possible even after extensive small bowel resections. This study aims to assess the incidence of SBS and potentially suitable candidates for intestinal transplantation among patients treated for AMI. METHODS: This population-based retrospective study comprised patients aged less than 70 years and diagnosed with AMI between January 2006 and October 2020 in Helsinki and Uusimaa health care district, Finland. RESULTS: Altogether, AMI was diagnosed in 711 patients, of whom 133 (19%) were aged below 70. An intervention was performed in 110 (83%) patients. Of these 133 patients, 16 (12%) were ruled outside active treatment due to extensive small bowel necrosis at exploratory laparotomy, of whom 6 (5%) were potentially suitable for intestinal transplantation. Two patients were considered as potential candidates for intestinal transplantation at bowel resection but died of AMI. Nine (7%) patients needed parenteral nutrition after resection, and two of them (2%) developed SBS. Only one patient needed long-term parenteral nutrition after hospital discharge. This patient remained dependent on parenteral nutrition but died before evaluation of intestinal transplantation could be carried out while the other patient was able to return to enteral nutrition. CONCLUSIONS: A small number of patients with AMI below 70 years of age are potentially eligible for intestinal transplantation.

BACKGROUND: Hartmann's procedure is a treatment option for perforated acute diverticulitis, especially when organ dysfunction(s) are present. Its use has been criticized mostly out of fear of high permanent stoma rate. The aim of this study was to investigate the rate of stoma reversal, reasons behind nonreversal, and safety of reversal surgery. METHODS: This was a single-center retrospective study of patients undergoing urgent Hartmann's procedure due to acute diverticulitis between the years 2006 and 2017 with follow-up until March 2021. RESULTS: A total of 3,319 episodes of diverticulitis in 2,932 patients were screened. The Hartmann's procedure was performed on 218 patients, of whom 157 (72%) had peritonitis (48 (22%) with organ dysfunction). At 2-years, 76 (34.9%) patients had died with stoma, 42 (19.3%) were alive with stoma, and 100 (45.9%) had undergone stoma reversal. The survival of patients with and without reversal were 100% and 42.7% at 1-year, 96.0% and 35.0% at 2-years and 88.9% and 20.7% at 5-years, respectively. The risk factors for nonreversal were old age, a need for outside assistance, low HElsinki Staging for Acute Diverticulitis stage, and higher C-reactive protein level upon hospital admission. The most common reasons for nonreversal in surviving patients were patient not willing to have the operation 18 (41%) and dementia 10 (23%). Twelve (12%) patients had a major complication after reversal (Clavien-Dindo IIIb-IV) and 90-day mortality after reversal was 0%. CONCLUSION: After the Hartmann's procedure for acute diverticulitis, one-third died, half underwent stoma reversal, and one-fifth did not undergo stoma reversal within 2 years. Patients who survive with stoma are either not willing to have reversal or have severe comorbidities excluding elective surgery. The Hartmann's procedure remains a viable option for high-risk patients with perforated acute diverticulitis.

BACKGROUND: As surgical complications inevitably occur, minimizing the failure-to-rescue rate is of paramount interest. Most of the failure-to-rescue research in colorectal surgery has previously focused on elective surgery and anastomotic dehiscence. The aim of this study was to characterize and compare the major postoperative complications demanding reoperation after elective versus emergency colorectal surgery, and to the identify risk factors for failure-to-rescue. METHODS: In this population-based retrospective multicenter cohort study, adult patients undergoing a reoperation for colorectal surgery complication between 2006 and 2017 in 10 hospitals were included. The data were manually extracted. Failure-to-rescue was defined as 90-day mortality after the reoperation. RESULTS: In total, 14,290 patients underwent index colorectal resection, of which 862 (5.8%) underwent emergency reoperation within 30 days (438 [4.3%] after elective, 424 [10.4%] after emergency index operation, P < .001). The failure-to-rescue overall rate was 17.4% (8.0% after elective vs 27.1% after emergency index operation, P < .001). The 4 most common complications were anastomotic dehiscence (36.6%, 316 patients), fascial rupture (23.5%, 203 patients), intra-abdominal bleeding (15.3%, 131 patients), and bowel obstruction (10.2%, 88 patients). The majority (640 patients, 74.2%) had 1 of these complications; 261 patients (30.3%) had multiple complications. In multivariable analyses, the only possibly preventable independent risk factor for failure-to-rescue was perioperative organ failure at the time of reoperation. CONCLUSION: Major complications requiring reoperation occur more than twice as often after emergency surgery and have a higher failure-to-rescue rate of >3× compared with elective surgery. The 4 most common complication types constitute three-fourths of the complications, providing a target for quality improvement.

OBJECTIVE: The exact incidence and outcomes of acute occlusive arterial mesenteric ischaemia (AMI) are unclear as most studies include only patients diagnosed correctly while alive. The aim of this study was to assess the incidence, mortality, and diagnostics of AMI by also including patients diagnosed post-mortem. METHODS: This retrospective study comprised patients diagnosed with AMI either alive or post-mortem between 2006 and 2015 within a healthcare district serving 1.6 million inhabitants. Key exclusion criteria were venous or non-obstructive ischaemia. RESULTS: A total of 470 patients were included in the study of which 137 (29%) were diagnosed post-mortem. The most common misdiagnoses on those not diagnosed alive were unspecified infection (n = 19, 17%), gastrointestinal bleeding (n = 13, 11%), and ileus (n = 13, 11%). Of those diagnosed alive (n = 333), 187 (56%) underwent active surgical or endovascular treatment. During the 2006 - 2015 period, the overall incidence of AMI was 3.05 (95% CI 2.78 - 3.34)/100 000 person years and 26.66 (95% CI 24.07 - 29.45) for those aged 70 years or more. The mean autopsy rate during the study period was 29% for the overall population (32% during 2006 - 2010 and 25% during 2011 - 2015) and 18% for those aged 70 years or more. Overall, the 90-day mortality was 83% in all patients. The ninety day mortality decreased, being 87% during the first period (2006 - 2010) and 79% during the second period (2011 - 2015) (p = .029), while at the same time the proportion of patients diagnosed alive rose from 71% to 80% (p = .030) and the number of endovascular revascularisations rose from 1% to 5% (p = .022). CONCLUSION: A significant proportion of patients with AMI are not diagnosed alive, which is reflected in the mortality rates. Post-mortem examinations and autopsy rate data continue to be key factors in epidemiological studies on AMI.
RESUMO
BACKGROUND: The Critical View of Safety (CVS) aims at preventing bile duct injuries (BDIs) in laparoscopic cholecystectomy (LCC). This study investigated CVS utilization among surgeons. METHODS: Photos from LCCs were scored for satisfactory CVS. Rates of satisfactory CVS, BDIs, and postoperative complications among residents and consultants were compared. A lecture on CVS was given halfway through the study. RESULTS: The study comprised 1532 patients. Residents had higher rates of satisfactory CVS in elective LCCs compared with consultants (34.9% vs. 23.0%, P <0.001), but not in emergency LCCs (18.4% vs. 15.0%, P =0.252). No significant differences in BDIs or postoperative complications emerged between residents and consultants. After the lecture, elective LCCs were photographed more frequently (80.3% vs. 74.0%, P =0.032), but rates of satisfactory CVS, BDIs, and postoperative complications remained unchanged. CONCLUSIONS: Utilization of CVS can be affected by a single lecture but affecting rates of satisfactory CVS may require stronger interventions.

BACKGROUND: Mild appendicitis may resolve spontaneously. The use of CT may lead to an overdiagnosis of uncomplicated appendicitis. The aims of this study were to examine whether early imaging results in more patients being diagnosed with acute appendicitis than initial observation, and to study the safety and feasibility of score-based observation compared with imaging in patients with equivocal signs of appendicitis. METHODS: Patients with suspected appendicitis with symptoms for fewer than 24â h and an Adult Appendicitis Score of 11-15 were eligible for this trial. After exclusions, patients were randomized openly into two equal-sized groups: imaging and observation. Patients in the imaging group had ultrasound imaging followed by CT when necessary, whereas those in the observation group were reassessed after 6-8â h with repeated scoring and managed accordingly. The primary outcome was the number of patients requiring treatment for acute appendicitis within 30 days. RESULTS: Ninety-three patients were randomized to imaging and 92 to observation; after exclusions, 93 and 88 patients respectively were analysed. In the imaging group, more patients underwent treatment for acute appendicitis than in the observation group: 72 versus 57 per cent (difference 15 (95 per cent c.i. 1 to 29) per cent). This suggests that patients with spontaneously resolving appendicitis were not diagnosed or treated in the observation group. Some 55 per cent of patients in the observation group did not need diagnostic imaging within 30 days after randomization. There was no difference in the number of patients diagnosed with complicated appendicitis (4 versus 2 per cent) or negative appendicectomies (1 versus 1 per cent) in the imaging and observation groups. CONCLUSION: Score-based observation of patients with early equivocal appendicitis results in fewer patients requiring treatment for appendicitis.

BACKGROUND: Despite the fact that emergency midline laparotomy is a risk factor for an incisional hernia, active research on hernia prevention in emergency settings is lacking. Different kinds of meshes and mesh positions have been studied in elective abdominal surgery, but no randomized controlled trials in emergency settings have been published thus far. METHOD: The PREEMER trial (registration number NCT04311788) is a multicentre, patient- and assessor-blinded, randomized controlled trial to be conducted in six hospitals in Finland. A total of 244 patients will be randomized at a 1 : 1 ratio to either the retrorectus mesh group, featuring a self-gripping prophylactic mesh, or to the no mesh (control) group, both closed by small-stitch 4 : 1 closure with continuous slowly absorbable monofilament suturing. The primary outcome of the PREEMER trial is the incidence of incisional hernia 2 years after surgery, which will be detected clinically and/or radiologically. Secondary outcomes are the Comprehensive Complication Index score, incidence of surgical-site infections and fascial dehiscence within 30 days of surgery; the incisional hernia repair rate and mesh- or hernia-related reoperations within the 2- and 5-year follow-ups; the incidence of incisional hernia within the 5-year follow-up; and quality of life measured by RAND-36, the Activities Assessment Scale and the PROMIS questionnaire within 30 days and 2 and 5 years from surgery. Additionally, health-economic explorative measures will be explored. CONCLUSION: The PREEMER trial will provide level 1 evidence on incisional hernia prevention in an emergency setting. REGISTRATION NUMBER: NCT04311788 (http://www.clinicaltrials.gov). Registered 7 March 2020.

BACKGROUND: Acute mesenteric ischemia (AMI) is a disease with high mortality and requires a multidisciplinary approach for effective management. A pathway and care bundle were developed and implemented with the objective to reduce mortality. The aim of this retrospective comparative study was to analyze the effects of the pathway on patient management and outcome. METHODS: All consecutive patients operated in a secondary and tertiary referral center because of occlusive arterial AMI were identified between 2014 and April 2020. The pathway aimed to increase overall awareness, and hasten and improve diagnostics and management. Patients treated before implementation of the pathway (pregroup, years 2014-2017) were compared with patients treated using the pathway (postgroup, May 2018 to April 2020). Univariate and multivariate analyses were used to compare the groups. RESULTS: There were 78 patients in the pregroup and 67 patients in the postgroup with comparable baseline characteristics and disease acuity. The postgroup was more often diagnosed with contrast-enhanced computed tomography (58 [74%] vs. 63 [94%], p = 0.001) and had shorter mean in-hospital delay to operating room (7 hours [interquartile range, 3.5-12.5] vs. 3 hours [interquartile range, 2-11], p = 0.023). Revascularization was done more often in the postgroup (53 [68%] vs. 56 [84%], p = 0.030) especially using endovascular treatment (26 [33%] vs. 43 [64%], p < 0.001). Thirty-day mortality was lower in the postgroup (23 [51%] vs. 17 [25%], p = 0.001). Being managed in the postgroup remained as a protective factor (odds ratio, 0.32; 95% confidence interval, 0.14-0.75; p = 0.008) for 30-day mortality in the multivariate analysis. CONCLUSION: Implementing a pathway and care bundle resulted in enhanced regional and in-hospital awareness of AMI, more appropriate computed tomography imaging, shorter in-hospital delays, increased number of revascularizations, and, hence, lower mortality. LEVEL OF EVIDENCE: Therapeutic/Care Management, level IV.

BACKGROUND: Selection of patients for open abdomen (OA) treatment in severe acute pancreatitis (SAP) is challenging. Treatment related morbidity and risk of adverse events are high; however, refractory abdominal compartment syndrome (ACS) is potentially lethal. Factors influencing the decision to initiate OA treatment are clinically important. We aimed to study these factors to help understand what influences the selection of patients for OA treatment in SAP. METHODS: A single center study of patients with SAP that underwent OA treatment compared with conservatively treated matched controls. RESULTS: Within study period, 47 patients treated with OA were matched in a 1:1 fashion with conservatively treated control patients. Urinary output under 20 ml/h (OR 5.0 95% CI 1.8-13.7) and ACS (OR 4.6 95% CI 1.4-15.2) independently associated with OA treatment. Patients with OA treatment had significantly more often visceral ischemia (34%) than controls (6%), P = 0.002. Mortality among patients with visceral ischemia was 63%. Clinically meaningful parameters predicting developing ischemia were not found. OA treatment associated with higher overall 90-day mortality rate (43% vs 17%, P = 0.012) and increased need for necrosectomy (55% vs 21%, P = 0.001). Delayed primary fascial closure was achieved in 33 (97%) patients that survived past OA treatment. CONCLUSION: Decreased urine output and ACS were independently associated with the choice of OA treatment in patients with SAP. Underlying visceral ischemia was strikingly common in patients undergoing OA treatment, but predicting ischemia in these patients seems difficult.
