Pattern and outcome of perforated peptic ulcer disease patient in four teaching hospitals in Addis Ababa, Ethiopia: a prospective cohort multicenter study

Global 30-day morbidity and mortality of surgery for perforated peptic ulcer: GRACE study

BACKGROUND

There is little international data on morbidity and mortality of surgery for perforated peptic ulcer (PPU). This study aimed to understand the global 30-day morbidity and mortality of patients undergoing surgery for PPU and to identify variables associated with these.

METHOD

We performed an international study of adults (≥ 18 years) who underwent surgery for PPU from 1st January 2022 to 30th June 2022. Patients who were treated conservatively or had an underlying gastric cancer were excluded. Patients were divided into subgroups according to age (≤ 50 and > 50 years) and time from onset of symptoms to hospital presentation (≤ 24 and > 24 h). Univariate and Multivariate analyses were carried out to identify factors associated with higher 30-day morbidity and mortality.

RESULTS

 1874 patients from 159 centres across 52 countries were included. 78.3% (n = 1467) of the patients were males and the median (IQR) age was 49 years (25). Thirty-day morbidity and mortality were 48.5% (n = 910) and 9.3% (n = 174) respectively. Median (IQR) hospital stay was 7 (5) days. Open surgery was performed in 80% (n = 1505) of the cohort. Age > 50 years [(OR = 1.7, 95% CI 1.4-2), (OR = 4.7, 95% CI 3.1-7.6)], female gender [(OR = 1.8, 95% CI 1.4-2.3), (OR = 1.9, 95% CI 1.3-2.9)], shock on admission [(OR = 2.1, 95% CI 1.7-2.7), (OR = 4.8, 95% CI 3.2-7.1)], and acute kidney injury [(OR = 2.5, 95% CI 1.9-3.2), (OR = 3.9), 95% CI 2.7-5.6)] were associated with both 30-day morbidity and mortality. Delayed presentation was associated with 30-day morbidity [OR = 1.3, 95% CI 1.1-1.6], but not mortality.

CONCLUSIONS

This study showed that surgery for PPU was associated with high 30-day morbidity and mortality rate. Age, female gender, and signs of shock at presentation were associated with both 30-day morbidity and mortality.

Analysis of risk factors for duodenal leak after repair of a duodenal perforation

BACKGROUND

Repairing of a duodenal perforation is a well accepted procedure, but clinically, approximately 4% of patients develop duodenal leaks after perforation repair, increasing the risk of death. We retrospectively analyzed clinical data from 168 patients at our hospital to explore risk factors for duodenal leak after perforation repair and developed a nomogram for predicting postoperative duodenal leak.

METHODS

This retrospective case-control study totalled 168 patients undergoing repair of a duodenal perforation with omentopexy at the General Surgery Department, Dongnan Hospital of Xiamen University, from January 2012 to January 2022. The patients were divided into the non-leak group and the leak group. Risk factors were evaluated by analyzing the patient's sex, shock, diameter and anatomic position of the ulcer, use of NSAIDS and Glucocorticoid, history of drinking, diabetes, chronic diseases, age, time of onset of symptoms and lab tests.

RESULT

One hundred fifty-six patients (92.9%) who did not develop leaks after repair of a duodenal perforation were included in the non-leak group, and 12 (7.1%) developed leaks were included in the leak group. In univariate analysis, there were significant differences between the two groups referring to age, shock, NSAIDs, albumin, and perforation size (P < 0.05). The area under the ROC curve for perforation diameter was 0.737, the p-value was 0.006, the optimal cutoff point was 11.5, sensitivity was 58.3%, and specificity was 93.6%, the positive predictive value is 41.1%, and the negative predictive value is 98.0%. In the internal validation of the performance of the nomogram, the C-index and AUC of the model were 0.896(95%CI 0.81-0.98), demonstrating that the nomogram model was well calibrated.

CONCLUSION

The study discussed the risk factors for postoperative duodenal leak in patients undergoing repair of a duodenal perforation, and a nomogram was constructed to predict the leak. Future prospective studies with large sample sizes and multiple centres are needed to further elucidate the risk of duodenal leak after repair of a duodenal perforation.

Clinical presentation and surgical management of perforated peptic ulcer in a tertiary hospital in Mogadishu, Somalia: a 5-year retrospective study

Background

Perforated peptic ulcer is a common surgical emergency condition worldwide, which is associated with significant morbidity and mortality if early diagnosis and immediate surgical management were not carried out. Perforation occurs in roughly 5% of PUD patients during their lifetime; this study aimed to explore the wide range of clinical presentations, associated risk factors, complications, and surgical management of perforated peptic ulcer patients.

Methods

A 5-year retrospective observational study on the clinical presentation and surgical management of perforated peptic ulcer is carried out in a tertiary hospital in Mogadishu, Somalia, Department of General Surgery, from January 2017 to December 2021. We included all patients undergoing operations with an intraoperative confirmed diagnosis of perforated peptic ulcer at the general surgery department. For operated patients, follow-up evaluation was performed in the outpatient department.

Results

Fifty-one patients underwent an emergency operation for perforated peptic ulcer during the study period. The sociodemographic distribution of patients was 45 (88.2%) males and 6 (11.8%) females, giving a male-to-female ratio of 7.5:1. The mean age of patients was 35.5 ± 16.8 years, and the peak frequency was in the third decade. The commonest presenting symptoms were sudden onset of severe epigastric pain in 42 (82.4%) patients. Patients who presented perforated peptic ulcer within 24 h of initiation of symptoms were free from complications. Age-group and delayed presentation > 48 h after onset of symptoms were linked to postoperative complications and were statistically significant (P 0.032 and P 0.005), respectively. Four patients died (mortality rate of 7.8%). Two patients were reoperated because of the failed primary repair, and 4 patients had > 5 cm intra-abdominal abscess image-guided percutaneous drainage, and the rest were given antibiotic therapy according to peritoneal fluid culture and sensitivity results. The most common microorganism isolated was E. coli 22% and Klebsiella 11%. Other rare microorganisms (pseudomonas, Staphylococcus aureus, and Candida spp.) were identified. In half (51%) of the patients with peritoneal fluid culture, no microorganism growth was seen.

Conclusion

The distribution of perforated peptic ulcer is common in the young age-group in the third decades of life. Delayed presentation of the disease is linked because most patients arrived from remote areas where proper facilities of health care and health education are not available and the patient might come to the hospital in an advanced stage of the disease. We suggest conducting further researches, health awareness related to complications over-the-counter drugs self-medication, and bad habit including smoking, and to improve health-seeking behaviors of society.

The global, regional and national burden of peptic ulcer disease from 1990 to 2019: a population-based study

Background

Peptic ulcer disease (PUD) is a common digestive disorder, of which the prevalence decreased in the past few decades. However, the decreasing tendency has plateaued in recent years due to changes in risk factors associated with the etiology of PUD, such as non-steroidal anti-inflammatory drug use. In this study, we investigated the epidemiological and the sociodemographic characteristics of PUD in 204 countries and territories from 1990 to 2019 based on data from the Global Burden of Disease, Injuries and Risk Factors (GBD) Study.

Methods

Demographic characteristics and annual prevalence, incidence, mortality, disability-adjusted life years (DALYs) and age-standardized death rate (ASR) data associated with PUD were obtained and analyzed. According to the sociodemographic index (SDI), the numbers of patients, ASRs, estimated annual percentage changes and geographical distributions were assessed with a generalized linear model and presented in world maps. All evaluations of numbers and rates were calculated per 100,000 population with 95% uncertainty intervals (UIs).

Results

In 2019, the global prevalence of PUD was approximately 8.09 [95% UI 6.79–9.58] million, representing a 25.82% increase from 1990. The age-standardized prevalence rate was 99.40 (83.86–117.55) per 100,000 population in 2019, representing a decrease of 143.37 (120.54–170.25) per 100,000 population from 1990. The age-standardized DALY rate in 2019 was decreased by 60.64% [74.40 (68.96–81.95) per 100,000 population] compared to that in 1990. In both sexes, the numbers and ASRs of the prevalence, incidence, deaths and DALYs were higher in males than in females over 29 years. Regionally, South Asia had the highest age-standardized prevalence rate [156.62 (130.58–187.05) per 100,000 population] in 2019. A low age-standardized death rate was found in the high-income super-region. Among nations, Kiribati had the highest age-standardized prevalence rate [330.32 (286.98–379.81) per 100,000 population]. Regarding socioeconomic status, positive associations between the age-standardized prevalence, incidence, death rate, DALYs and SDI were observed globally in 2019.

Conclusions

Morbidity and mortality due to PUD decreased significantly from 1990 to 2019, while a gradual upward inclination has been observed in recent 15 years, which might be associated with changes in risk factors for PUD. Attention and efforts by healthcare administrators and society are needed for PUD prevention and control.
