Postoperative Complications and Outcome After Emergency Laparotomy: A Retrospective Study.

BACKGROUND: Emergency laparotomy (EL) is a common urgent surgical procedure with high risk for postoperative complications. Complications impair the prognosis and prolong the hospital stay. This study explored the incidence and distribution of complications and their impact on short-term mortality after EL. METHODS: This was a retrospective single-center register-based cohort study of 674 adults undergoing midline EL between May 2015 and December 2017. The primary outcome was operation-related or medical complication after EL. The secondary outcome was mortality in 90-day follow-up. Multivariate logistic regression analyses were used to identify independent risk factors for complications. RESULTS: A total of 389 (58%) patients developed complications after EL, including 215 (32%) patients with operation-related complications and 361 (54%) patients with medical complications. Most of the complications were Clavien-Dindo classification type 4b (28%) and type 2 (22%). Operation-related complications occurred later compared to medical complications. Respiratory complications were the most common medical complications, and infections were the most common operation-related complications. The 30- and 90-day mortalities were higher in both the medical (17.2%, 26.2%) and operation-related complication groups (13.5%, 24.2%) compared to patients without complications (10.5% and 4.8%, 14.8% and 8.0%). Low albumin, high surgical urgency, excessive alcohol consumption and medical complications were associated with operation-related complications. Older age, high ASA class and operation-related complications were associated with medical complications. CONCLUSIONS: This study demonstrated that EL is associated with a high risk of complications and poor short-term outcome. Complications impair the prognosis regardless of which kind of EL is in question.

Outcomes in patients requiring intensive care unit (ICU) admission after emergency laparotomy: A retrospective study.

PURPOSE: Outcomes after emergency laparotomy (EL) are poor. These patients are often admitted to an intensive care unit (ICU). This study explored outcomes in patients who were admitted to an ICU within 48 h after EL. MATERIALS AND METHODS: This retrospective single-center registry study included all patients over 16 years of age that underwent an EL and were admitted to an ICU within 48 h after surgery in Oulu University Hospital, Finland between January 2005 and May 2015. Survival was followed until the end of 2019. RESULTS: We included 525 patients. Hospital mortality was 13.3%, 30-day mortality was 17.3%, 90-day mortality was 24.2%, 1-year mortality was 33.0%, and 5-year mortality was 59.4%. Survivors were younger (57 [45-70] years) than the non-survivors (73 [62-80] years; p < .001). According to the Cox regression model, death during the follow-up was associated with age, APACHE II-score, lower postoperative CRP levels and platelet count of the first postoperative day, and the admission from the post-anesthesia care unit (PACU) to the ICU instead of direct ICU admission. CONCLUSION: Age, high APACHE II-score, low CRP and platelet count, and admission from the PACU to the ICU associated with mortality after EL in patients admitted to an ICU within 48 h after EL.

Socio-economic factors and rural-urban differences in patients undergoing emergency laparotomy.

Background: Emergency laparotomy (EL) is a common surgical procedure with high rates of mortality and complications. Socio-economic circumstances and regional differences have an influence on the utilization of care and outcomes in many diagnostic groups, but there are only a few studies focusing on their effect in EL population. The aim of this study was to examine the socio-economic and regional differences in the rate of EL within one tertiary care hospital district. Methods: Retrospective single-center study of 573 patients who underwent EL in Oulu University Hospital between May 2015 and December 2017. The postal code area of each patient's home address was used to determine the socio-economic status and rurality of the location of residence. Results: The age-adjusted rate of EL was higher in patients from low-income areas compared to patients from high-income areas [1.46 ((95% CI 1.27-1.64)) vs. 1.15 (95% CI, 0.96-1.34)]. The rate of EL was higher in rural areas compared to urban areas [1.29 (95% CI 1.17-1.41 vs. 1.42 (1.18-1.67)]. Peritonitis was more common in patients living in low-income areas. There were no differences in operation types or mortality between the groups. Conclusions: The study findings suggest that there are socio-economic and regional differences in the need of EL. The patients living in low-income areas had a higher rate of EL and a higher rate of peritonitis. These differences cannot be explained by patient demographics or comorbidities alone.

Evolution of pancreatic surgery over time and effects of centralization-a single-center retrospective cohort study.

Background: Short-term outcomes of pancreatic surgery have improved globally during the last two decades. Long-term survival of resectable pancreatic ductal adenocarcinoma (PDAC) has also shown slight improvement. We describe a cohort of 566 consecutive pancreatectomies performed at a Northern Finnish tertiary center. We analyze the trends in short-term outcomes of all-cause pancreatic surgery and long-term survival of PDAC patients. Methods: All pancreatic resections performed at the Oulu University Hospital during years 2000-2020 were included. Patient data was analyzed in four time periods (2000-2005, 2006-2010, 2011-2015 and 2016-2020). Clinicopathological parameters of patients and tumors, complication data and short-term mortality were recorded for all patients and compared between time quartiles. Long-term survival and administration rates of neo-, and/or adjuvant therapy of PDAC patients were analyzed. Results: A total of 566 pancreatectomies were performed during the study period: 359 (63%) pancreatoduodenectomies (PDs), 130 (23.0%) open left pancreatectomies (LPs), 45 (8.0%) laparoscopic LPs, 26 (5.1%) total pancreatectomies (TPs), and 6 (1.1%) enucleations. Median age of patients was 63 [57-71] years, and 49% [267] of patients were men. Number of pancreatectomies per time period increased from 67 in 2000-2005 to 266 in 2016-2020. American Society of Anesthesiologists (ASA) Physical Classification III patients and T3 tumors were more frequently operated on in later time periods. Complication rates remained at constant low levels throughout the study period, but reoperation rate increased from 9.4% in 2000-2010 to 16.2% in 2011-2020. Short-term (90-day) mortality after pancreatectomy decreased from 3.1% to 0.74%, while 5-year survival improved from 14.3% in 2006-2011 to 21.4% in 2011-2015. Resection rate of diagnosed PDAC cases, as reported by the Finnish Cancer Registry (FCR) for the catchment area, increased from 3.2% to 14.9% over the study period. Conclusions: The hospital volume of pancreatectomies has increased substantially, while complications and postoperative mortality have remained at acceptable levels. Long-term survival and resection rate of PDAC patients showed notable improvement over two decades.

Nutrition delivery after emergency laparotomy in surgical ward: a retrospective cohort study.

PURPOSE: Adequate nutrition after major abdominal surgery is associated with less postoperative complications and shorter hospital length of stay (LOS) after elective procedures, but there is a lack of studies focusing on the adequacy of nutrition after emergency laparotomies (EL). The aim of the present study was to investigate nutrition adequacy after EL in surgical ward. METHODS: The data from 405 adult patients who had undergone emergency laparotomy in Oulu University Hospital (OUH) between years 2015 and 2017 were analyzed retrospectively. Nutrition delivery and complications during first 10 days after the operation were evaluated. RESULTS: There was a total of 218 (53.8%) patients who were able to reach cumulative 80% nutrition adequacy during the first 10 postoperative days. Patients with adequate nutrition (> 80% of calculated calories) met the nutritional goals by the second postoperative day, whereas patients with low nutrition delivery (< 80% of calculated calories) increased their caloric intake during the first 5 postoperative days without reaching the 80% level. In multivariate analysis, postoperative ileus [4.31 (2.15-8.62), P < 0.001], loss of appetite [3.59 (2.18-5.93), P < 0.001] and higher individual energy demand [1.004 (1.003-1.006), P = 0.001] were associated with not reaching the 80% nutrition adequacy. CONCLUSIONS: Inadequate nutrition delivery is common during the immediate postoperative period after EL. Oral nutrition is the most efficient way to commence nutrition in this patient group in surgical ward. Nutritional support should be closely monitored for those patients unable to eat. TRIAL REGISTRATION NUMBER: Not applicable.

Long-term Outcomes After Emergency Laparotomy: a Retrospective Study.

BACKGROUND: Emergency laparotomy (EL) is a common surgical operation with poor outcomes. Patients undergoing EL are often frail and have chronic comorbidities, but studies focused on the long-term outcomes after EL are lacking. The aim of the present study was to examine the long-term mortality after EL. METHODS: We conducted a retrospective single-center cohort study of 674 adults undergoing midline EL between May 2015 and December 2017. The follow-up lasted until September 2020. The primary outcome was 2-year mortality after surgery. The secondary outcome was factors associated with mortality during follow-up. RESULTS: A total of 554 (82%) patients survived > 90 days after EL and were included in the analysis. Of these patients, 120 (18%) died during the follow-up. The survivors were younger than the non-survivors (median [IQR] 64 [49-74] vs. 71 [63-80] years, p < 0.001). In a Cox regression model, death during follow-up was associated with longer duration of operation (OR 2.21 [95% CI 1.27-3.83]), higher ASA classification (OR 2.37 [1.15-4.88]), higher CCI score (OR 4.74 [3.15-7.14]), and postoperative medical complications (OR 1.61 [1.05-2.47]). CONCLUSIONS: Patient-related factors, such as higher ASA classification and CCI score, were the most remarkable factors associated with poor long-term outcome and mortality after EL.
