Perioperative mortality rate and its predictors after emergency laparatomy at Debre Markos comprehensive specialized hospital, Northwest Ethiopia: 2023: retrospective follow-up study

BACKGROUND

Emergency laparatomy is abdominal surgery associated with a high rate of mortality. There are few reports on rates and predictors of postoperative mortality, whereas disease related or time specific studies are limited. Understanding the rate and predictors of mortality in the first 30 days (perioperative period) is important for evidence based decision and counseling of patients. This study aimed to estimate the perioperative mortality rate and its predictors after emergency laparatomy at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia, 2023.

METHODS

This was a Hospital-based retrospective follow-up study conducted at Debre Markos Comprehensive Specialized Hospital in Ethiopia among patients who had undergone emergency laparatomy between January 1, 2019 and December 31, 2022. Sample of 418 emergency laparatomy patients selected with simple random sampling technique were studied. The data were extracted from March 15, 2023 to April 1, 2023 using a data extraction tool, cleaned, and entered into Epi-Data software version 3.1 before being exported to STATA software version 14.1 for analysis. Predictor variables with P value < 0.05 in multivariable Cox regression were reported.

RESULTS

Data of 386 study participants (92.3% complete charts) were analyzed. The median survival time was 18 days [IQR: (14, 29)]. The overall perioperative mortality rate in the cohort during the 2978 person-days of observations was 25.5 per 1000 person-days of follow-up [95% CI: (20.4, 30.9))]. Preoperative need for vasopressor [AHR: 1.8 (95% CI: (1.11, 2.98))], admission to intensive care unit [AHR: 2.0 (95% CI: (1.23, 3.49))], longer than three days of symptoms [AHR: 2.2 (95% CI: (1.15, 4.02))] and preoperative sepsis [AHR: 1.8 (95% CI: (1.05, 3.17))] were identified statistically significant predictors of perioperative mortality after emergency laparatomy.

CONCLUSIONS

The perioperative mortality rate is high. Preoperative need for vasopressors, admission to intensive care unit, longer than three days of symptoms and preoperative sepsis were predictors of increased perioperative mortality rate.

Fatal Road Traffic Accidents and Associated Factors in North Shewa Zone, Central Ethiopia: A Cross-Sectional Study

Background

Road traffic accidents (RTAs) are among the top three global causes of death among people aged 15 to 44 years. More importantly, it is the main cause of death and permanent disability among young people aged 15 to 29 years. This study aimed to assess the magnitude of fatal traffic accidents and the factors associated with them in the North Shewa Zone, Central Ethiopia, from 2013 to 2018.

Method

An institution-based cross-sectional study was conducted in all registered RTAs from July 2013 to June 2018 that had full documentation. The data extraction tool was developed based on the daily RTA registration book format that was utilized. Data was entered into Epi-data version 3.1 and then exported to SPSS version 21 for analysis. Logistic regression analysis was used to assess the relationship between the factors and the fatality of RTA. P-values less than 0.05 were reported as statistically significant.

Results

Among 846 RTAs studied, 351 (41.5%) were found fatal, while 495 (58.5%) caused non-fatal injuries. Failure to give priority to pedestrians was 2.8 times (AOR = 2.8, 95% CI: 1.3, 5.9) more likely to cause fatal RTAs than drivers who failed to maintain distance between vehicles. Pedestrians were 2.7 times (AOR = 2.7, 95% CI: 1.1, 6.7) more likely to die in RTAs than drivers.

Conclusion

The fatality of RTA was high. Failure to give priority to pedestrians and being a pedestrian were strong predictors of death. The North Shewa Zone Traffic Police Department and police officers should focus on enforcing traffic safety laws.

Perioperative Adverse Outcome and Its Predictors After Emergency Laparotomy Among Sigmoid Volvulus Patients: Retrospective Follow-Up Study

Background

Acute sigmoid volvulus is a surgical emergency with closed-loop obstruction of the colon that often requires emergency laparotomy, which is associated with a multitude of post-operative complications. Although sigmoid volvulus is the main cause of intestinal obstruction in Ethiopia, local studies of its management outcomes are limited.

Objective

To assess the magnitude and predictors of adverse perioperative outcomes of emergency laparotomy for acute sigmoid volvulus in the Debre Markos Comprehensive Specialized Hospital (DMCSH), Amhara region, Ethiopia in 2023.

Methods

This was a retrospective follow-up study. Descriptive statistics were used to measure perioperative outcomes and other study variables. Bivariable and multivariable logistic regression models were used to identify the predictors of adverse surgical outcomes. Associations were considered significant at p < 0.05 (95% confidence interval).

Results

In total, 170 study participants were enrolled, with a response rate of 91.4%. Forty-nine patients (28.8%) developed perioperative adverse outcomes. Pneumonia (29 patients, 28.1%), surgical site infection (19 patients, 18.4%), and wound dehiscence (10 patients, 9.7%) were the most common complications. Pre-operative shock [AOR: 3.87 (95% CI: (1.22, 12.28))], pus or fecal matter contamination of the peritoneum [AOR: 4.43 (95% CI: (1.35, 14.47)], and a higher American Society of Anesthesiologists (ASA) score [AOR: 2.37 (95% CI: (1.05, 5.34))] were identified as predictors of perioperative adverse events.

Conclusion

The perioperative adverse outcomes in this study were higher than those reported in Ethiopian national and global reports following emergency laparotomies. Hypotension at presentation, pus and/or fecal matter contamination of the peritoneum, and higher ASA scores are strong predictors of increased perioperative adverse outcomes. Therefore, healthcare providers and institutions involved in the delivery of emergency surgical care should emphasize the importance of early surgical intervention, adequate resuscitation, and patient monitoring to improve perioperative outcomes.

Community-Based Health Insurance Utilization and Its Determinants among Informal Workers: Cross-Sectional Study

Background

Ethiopia has implemented a community-based health insurance (CBHI) program to provide coverage to 80% of the population and shield underprivileged individuals from the detrimental effects of exorbitant medical expenses. However, there is a paucity of data regarding its utilization and pertinent concerns. This study aimed to evaluate the utilization of CBHI and its associated factors among informal workers in Berek District.

Methods

This community-based cross-sectional study was conducted between June 15 and July 15, 2022. The sample population comprised 538 households selected using a multistage sampling approach. Data analysis was done using SPSS Version 26. Variables with P-values of less than 0.25 during the bivariate analysis were selected for multivariate analysis using binary logistic regression. The statistical significance threshold was set at a p-value of 0.05.

Results

The utilization of Community-Based Health Insurance (CBHI) was 49.8%. Age between 30 and 39 years, monthly earnings of less than 1500 Ethiopian Birr, presence of chronic illness, membership in social organization, and possessing adequate knowledge were found to have a statistically significant association with the use of CBHI.

Conclusion

The utilization of CBHI was low within the confines of this district Age, income, social group membership, and chronic illnesses were significantly associated with CBHI utilization.

Giant renal angiomyolipoma: A case report

INTRODUCTION

Renal angiomyolipoma (AML), which is a rare solid kidney tumor with benign characteristics, also known as a renal hamartoma, can exhibit various clinical symptoms and severe consequences may arise if the lesion becomes large.

PRESENTATION OF THE CASE

A 58-year-old woman was admitted to a hospital, with general fatigue, abdominal swelling, and epigastric fullness. Upon examination, a large mass was palpated, which occupied almost the entire right abdomen. The abdominal computed tomography scan revealed a large right renal mass measuring 22 × 18 × 8 cm, which was exophytic and heterogeneous with a large fat component and an enhancing solid part. The tumor was successfully excised through a generous right subcostal incision with left-side extension. The total weight of the resected specimen was 2500 g, which appears to be the largest angiomyolipoma ever resected in Ethiopia.

DISCUSSION

Renal AML, a benign tumor derived from mesenchymal components, is sometimes referred to as a "hamartoma" due to its variable makeup. The most common complaints of patients with renal AML are lower back pain, hematuria, and physical finding of hypotension (shock), though patients with giant AML, as in this case, may also experience gastrointestinal symptoms due to the mass' compression.

CONCLUSION

Although treatment options requiring contemporary medical technologies and skilled manpower are difficult to offer in set ups of resource-limited countries, such as the one we reported from, giant renal angiomyolipoma can be treated safely with open nephrectomy.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

BACKGROUND

Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.

METHODS

This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries.

RESULTS

In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.

CONCLUSION

This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

Magnitude and predictors of unfavorable management outcome in surgically treated patients with intestinal obstruction in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Unless an emergency surgical intervention is conducted, intestinal obstruction may result in high morbidity and mortality. In Ethiopia, the magnitude and predictors of unfavorable management outcomes in surgically treated patients with intestinal obstruction are highly variable and inconsistent. The aim of this study was; therefore, to estimate the overall prevalence of unfavorable management outcome and its predictors among surgically treated patients with intestinal obstruction in Ethiopia.

METHOD

We searched articles from databases from June 1, 2022, to August 30, 2022. Cochrane Q test statistics and I² tests were applied. We used a random-effect meta-analysis model to overcome the impact of heterogeneity among the included studies. In addition, the association between risk factors and unfavorable management outcome in surgically treated patients with intestinal obstruction was investigated.

RESULTS

This study included a total of twelve articles. The pooled prevalence of unfavorable management outcome in surgically treated patients with intestinal obstruction was 20.22% (95% CI: 17.48-22.96). According to a sub-group analysis by region, Tigray region had the highest prevalence of poor management outcome, which was 25.78% (95% CI: 15.69-35.87). Surgical site infection was the most commonly reported symptom of poor management outcome (8.63%; 95% CI: 5.62, 11.64). The length of postoperative hospital stays (95% CI: 3.02, 29.08), duration of illness (95% CI: 2.44, 6.12), presence of comorbidity (95% CI: 2.38, 10.11), dehydration (95% CI: 2.07, 17.40), and type of intraoperative procedure (95% CI: 2.12, 6.97) were all significantly associated with unfavorable management outcome of intestinal obstruction among surgically treated patients in Ethiopia.

CONCLUSION

According to this study, the magnitude of unfavorable management outcome was high among surgically treated patients in Ethiopia. Unfavorable management outcome was significantly associated with the length of postoperative hospital stays, duration of illness, comorbidity, dehydration, and type of intraoperative procedure. Medical, surgical and public health measures are pivotal to reduce unfavorable management outcome in surgically treated intestinal obstruction patients in Ethiopia.

The infection spreads to adjacent planes destructing facial planes, aspirations of infective particles, or septic embolism to distant areas. Understanding the rare presentations will help early diagnosis and treatment.

PRESENTATION OF CASE

This is about a 40 years-old man who presented with painful anterior neck swelling of 7 days duration. A diagnosis of Ludwig's angina with unilateral facial nerve paralysis and treated with immediate incision and drainage.

CLINICAL DISCUSSION

Ludwig's may present clinical with a variety of complications. This complication may be related to ongoing sepsis or mass effects manifesting with airway compromise or nerve palsy.

CONCLUSION

Although facial nerve palsy associated with Ludwig's angina is rare, it improves with immediate surgical decompression.

Sub-chronic toxicity of the aqueous leaf extract of Ocimum lamiifolium Hochst. ex Benth on biochemical parameters and histopathology of liver and kidney in rats: in vivo and in- silico toxicity studies

BACKGROUND

The aerial part of Ocimum lamiifolium is commonly used in Ethiopian traditional medicine. Although this plant is mostly used in traditional medicine, its safety profile has not been documented yet. The aim of this study was to assess the sub-chronic toxicity of O. lamiifolium aqueous extract in rats and to determine the toxicity profile of GC-MS identified bioactive compounds obtained from essential oil of O. lamiifolium using in silico toxicity methods.

METHODS

Eighty rats (40 male and 40 female) were randomly assigned to four groups of ten rats per sex/group. For 90 days, Groups I-III received 200, 400, and 600 mg/kg bw of aqueous extract of O. lamiifolium, respectively. Distilled water was given to Group IV (control). Clinical observations, food intake, and rat weight were all recorded during the experiment. In addition, several biochemical parameters, organ weight, and histology of the liver and kidney were all evaluated. For the in-silico toxicity study, GC-MS identified bioactive compounds in O. lamiifolium essential oil were obtained from published articles. The compounds two-dimensional structures were constructed using Chemdraw. The two-dimensional structures were converted into a simplified molecular input line entry system (SMILES) using the Swiss ADMET web tool. Furthermore, the toxicity parameters were predicted using the ProTox II server.

RESULTS

The administration of an aqueous extract of O. lamiifolium leaves significantly (p < 0.05) reduced the test animals' food intake and body weight gain. In the high dose (600 mg/kg bw) treated group, the serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase levels were significantly increased (p < 0.05). In female rats given 600 mg/kg bw of O. lamiifolium, the levels of serum urea were also increased. In addition, rats given 600 mg/kg bw had significantly lower blood glucose levels than the control group (p < 0.05). Doses up to 400 mg/kg bw didn't bring a significant change to the histology of the liver. However, in the high dose (600 mg/kg bw) treated group, some female rats' livers showed mild sinusoidal and central vein dilatation, as well as parenchymal necrosis. our findings showed that all compounds derived from the essential oil of O. lamiifolium showed no mutagenicity or cytotoxicity. However, 30% of the compounds tested were hepatotoxic, 20% carcinogenic, and 20% immunotoxin.

CONCLUSION

Our findings showed that oral administration of O. lamiifoliums aqueous extract up to a dose of 400 mg/kg bw is not toxic. However, high-dose (600 mg/kg bw) significantly affected the food consumption and weight gain of the experimental rats and the serum concentration of some liver and kidney enzymes were also significantly increased. Additionally, a considerable proportion of the tested compounds were predicted to be hepatotoxic, carcinogenic and immunotoxin. Furthermore, before employing O. lamiifolium preparations as drugs, a chronic toxicity research on the essential oil as well as its components that exhibited toxicity in the in-silico toxicity study is needed. Finally, use high doses of O. lamiifolium leaves with caution.

Breast hydatid cyst presented as a fluctuant painless lump mimicking galactocele: A case report

Hydatid disease is a zoonosis caused by the Echinococcus species. The liver and lungs are where it generally seen, with breast involvement being extremely uncommon. This is a case of a woman aged 28 years who presented with a progressive painless swelling on the left breast, which was fluctuant and nontender, detected on the upper outer quadrant. The cytologic evaluation yielded a crystal-clear fluidal aspirate composed of a few laminated metachromatic materials and the mass sonographically appeared as an anechoic cystic mass having a double-layered wall with posterior acoustic enhancement. A radical pericystectomy was performed after the preoperative diagnosis of breast hydatid cyst was entertained, and the diagnosis was later confirmed by histopathology. Although isolated breast hydatid cysts are uncommon, they can happen and may mimic other cystic and solid masses of the breast clinically. Thus, radiologic assessment with cytopathologic correlation is imperative for precise preoperative diagnosis and to minimize the risk of intraoperative complications.
