Risk factors influencing the short-term results of gastroduodenal perforation

Predictive Role of Acute Physiology and Chronic Health Evaluation II (APACHE II) in Patients With Peritonitis at the National Hospital Abuja

BACKGROUND

A validated tool may facilitate assessing the severity of peritonitis among surgical patients. This study evaluates the predictive role of Acute Physiology and Chronic Health Evaluation II (APACHE II) in the surgical outcomes of patients managed for peritonitis in Abuja.

METHOD

This is a prospective study of consecutive adult patients managed for peritonitis by the general surgery unit of National Hospital Abuja (NHA) over a 19-month period (September 2020 through March 2022). Patient characteristics and treatment outcomes were recorded in a structured proforma and analyzed using SPSS Statistics version 25 (IBM Corp., Released 2017; IBM SPSS Statistics for Windows, Version 25.0; Armonk, NY: IBM Corp.). The accuracy, sensitivity, specificity, and threshold of APACHE II were derived from the receiver operating characteristic (ROC) curve analysis and its coordinates.

RESULTS

There were 54 patients with peritonitis during the study period, with a male-to-female ratio of 2.6:1. This study's mortality and morbidity rates were 13.0% and 63.0%, respectively. The APACHE II score at admission was positively correlated with the likelihood of postoperative mortality, morbidity, number of postoperative complications, ICU admission, and length of hospital admission. The average APACHE II score of patients in this study was 7.1±5.2. APACHE II best-predicted mortality by the ROC curve at a threshold point of 9 (sensitivity of 85.7%, specificity of 70.2%, the accuracy of 86.8%, P-value 0.002). At a threshold score of 6, APACHE II was significantly associated with the occurrence of postoperative morbidity (sensitivity of 74.3%, specificity of 73.7%, accuracy of 75.2%, P-value = 0.043).

CONCLUSIONS

This study confirms that the APACHE II score at admission can predict the outcome of surgery within the first 30 days post-surgery among adult patients who had peritonitis at NHA.

Impact of the coronavirus disease 2019 pandemic on the management of acute peptic ulcer perforation: to be reconsidered(?)

OBJECTIVE

Peptic ulcer perforation presents the most serious complication of ulcer disease with mortality that varies significantly depending on the age and conditions. The coronavirus disease 2019 pandemic was effective worldwide in 2020 and continues to date. The aim of this study was to investigate the initial clinical parameters and short-term outcomes of patients with acute peptic ulcer perforation before and during the coronavirus disease 2019 pandemic.

METHODS

A retrospective cohort study was conducted in the Department of Surgery, University Hospital Ostrava, Czech Republic. The patients undergoing surgical modality of a simple suture of peptic ulcer perforation with/without omentoplasty in the post-coronavirus disease 2019 (January 1, 2020 to December 31, 2021) and the pre-coronavirus disease 2019 (January 1, 2018 to December 31, 2019) had been incorporated in this study.

RESULTS

This study included a total of 46 cases (26 in the pre-coronavirus disease 2019, 20 in the post-coronavirus disease 2019). The age, body mass index, Boey score, duration of symptoms, surgery time, and length of hospital stay were comparable in both study subgroups. During the coronavirus disease 2019 pandemic, patients were admitted with a statistically significantly lower degree of perioperative risk according to the American Society of Anesthesiologists classification (p=0.013). Notably, 30-day postoperative morbidity was significantly higher in pre-coronavirus disease 2019 (73.1 vs. 55.0%, p=0.038). The mortality rate in the laparoscopic group was 13.6%, in the laparotomy group 41.4%, and the mortality rate was higher in pre-coronavirus disease 2019 than in post-coronavirus disease 2019 (34.6 vs. 20.0%, p=0.166).

CONCLUSION

In fact, the coronavirus disease 2019 pandemic had not significantly influenced therapeutic management and short-term outcomes of patients undergoing acute surgical repair of peptic ulcer perforation.

Are admission laboratory values in isolation meaningful for predicting surgical outcome in patients with perforated peptic ulcers?

Background

The study aimed to calculate the predictive value of admission laboratory values in patients with perforated peptic ulcers.

Methods

A retrospective, cohort analytical, observational study was performed, including patients with surgically confirmed perforated peptic ulcers over a 5-year period. Demographic data and admission laboratory values were collected from hospital electronic databases. Outcomes measured were in-hospital mortality, intensive care unit (ICU) admission and length of stay. The significance of categorical variables was calculated by chi-square and Fisher's exact test. Logistic regression analysis was performed to determine univariately statistically significant variables.

Results

In total, 188 patients met the inclusion criteria. The median age was 46 (range 15-87) years with a male predominance of 71.3 % (n = 134). The median length of hospital stay was 7 (range 1-94) days and 31.4 % (n = 59) of patients were admitted to the ICU. Post-operative in-hospital mortality was 25.0 % (n = 47). Predicting the categorical outcome of in-hospital mortality, abnormal haemoglobin, platelet count, urea, creatinine and potassium levels were all found to be statistically significant in the univariate analysis. Age (odds ratio [OR] 1.03), haemoglobin (OR 4.36) and creatinine (OR 7.76) levels were significant in the multivariate analysis.

Conclusions

Mortality rate among patients with perforated peptic ulcer disease is still substantial. Admission laboratory values showed statistical significance as outcome indicators and were valuable to assist in predicting the prognosis. An abnormally high serum creatinine level was the strongest single predictor of both mortality and ICU admission.

Key message

Initial laboratory findings of patients admitted for perforated peptic ulcer showed that an abnormally high serum creatinine level was the strongest single predictor of both mortality and ICU admission.

Risk Factors for Mortality in Emergently Admitted Patients with Acute Gastric Ulcer: An Analysis of 15,538 Patients in National Inpatient Sample, 2005-2014

Background: Patients admitted emergently with a primary diagnosis of acute gastric ulcer have significant complications including morbidity and mortality. The objective of this study was to assess the risk factors of mortality including the role of surgery in gastric ulcers. Methods: Adult (18−64-year-old) and elderly (≥65-year-old) patients admitted emergently with hemorrhagic and/or perforated gastric ulcers, were analyzed using the National Inpatient Sample database, 2005−2014. Demographics, various clinical data, and associated comorbidities were collected. A stratified analysis was combined with a multivariable logistic regression model to assess predictors of mortality. Results: Our study analyzed a total of 15,538 patients, split independently into two age groups: 6338 adult patients and 9200 elderly patients. The mean age (SD) was 50.42 (10.65) in adult males vs. 51.10 (10.35) in adult females (p < 0.05). The mean age (SD) was 76.72 (7.50) in elderly males vs. 79.03 (7.80) in elderly females (p < 0.001). The percentage of total deceased adults was 1.9% and the percentage of total deceased elderly was 3.7%, a difference by a factor of 1.94. Out of 3283 adult patients who underwent surgery, 32.1% had perforated non-hemorrhagic ulcers vs. 1.8% in the non-surgical counterparts (p < 0.001). In the 4181 elderly surgical patients, 18.1% had perforated non-hemorrhagic ulcers vs. 1.2% in the non-surgical counterparts (p < 0.001). In adult patients managed surgically, 2.6% were deceased, while in elderly patients managed surgically, 5.5% were deceased. The mortality of non-surgical counterparts in both age groups were lower (p < 0.001). The multivariable logistic regression model for adult patients electing surgery found delayed surgery, frailty, and the presence of perforations to be the main risk factors for mortality. In the regression model for elderly surgical patients, delayed surgery, frailty, presence of perforations, the male sex, and age were the main risk factors for mortality. In contrast, the regression model for adult patients with no surgery found hospital length of stay to be the main risk factor for mortality, whereas invasive diagnostic procedures were protective. In elderly non-surgical patients, hospital length of stay, presence of perforations, age, and frailty were the main risk factors for mortality, while invasive diagnostic procedures were protective. The following comorbidities were associated with gastric ulcers: alcohol abuse, deficiency anemias, chronic blood loss, chronic heart failure, chronic pulmonary disease, hypertension, fluid/electrolyte disorders, uncomplicated diabetes, and renal failure. Conclusions: The odds of mortality in emergently admitted geriatric patients with acute gastric ulcer was two times that in adult patients. Surgery was a protective factor for patients admitted emergently with gastric perforated non-hemorrhagic ulcers.

Laparoscopic Repair Modality of Perforated Peptic Ulcer: Less Is More?

Perforation, per se, presents the most serious complication of peptic ulcer disease with a mortality rate that cannot be underestimated. Surgery is the only treatment option, which can be performed laparoscopically or via conventional laparotomy. The present study aimed to compare the short-term outcomes of laparoscopy and laparotomy techniques in the surgical treatment of peptic ulcer perforation. A retrospective study design was structured to compare the perioperative and short-term postoperative outcomes of 102 patients who had undergone laparoscopic and conventional repair of the perforated peptic ulcer over a six-year interval (January 1, 2016, to December 31, 2021). Of these, 44 (43.1%) had undergone laparoscopic repair while 58 (56.9%) had surgical repair via conventional laparotomy. The operative time and length of hospital stay were comparable in both subgroups (p=0.984 and p =0.585). Nevertheless, 30-day postoperative morbidity was significantly higher in the open surgery subgroup (75.9% vs. 59.1%, p= 0.032). The risk of relaparotomy was similar in both study subgroups; however, suture dehiscence as a reason for surgical revision was significantly more frequent in the laparoscopic subgroup (13.6% vs 3.4%). Of note, the mortality rate in the laparoscopic group of patients was 13.6%, and in the laparotomy group 41.4%. The laparoscopic approach to peptic ulcer perforation is the procedure of choice for low-risk patients. Conventional surgery seems to be associated with a significantly higher incidence of severe postoperative complications and mortality. However, the higher mortality in these patients is probably related to their worse initial clinical condition.

Is it possible to reduce the surgical mortality and morbidity of peptic ulcer perforations?

Objective

Peptic ulcer perforation is a life-threatening situation requiring urgent surgical treatment. A novel vision in peptic ulcer perforation is necessary to fill the gaps created by antiulcer medication, aging of the patients, and presentation of resistant cases in our era. In this study, we aimed to share our findings regarding the effects of various risk factors and operative techniques on the mortality and morbidity of patients with peptic ulcer perforation.

Material and Methods

Data from 112 patients presenting at our Training and Research Hospital Emergency Surgery Department between January 2010 and December 2015 who were diagnosed with PUP through physical examination and laboratory and radiological tests and operated at the hospital have been retrospectively analyzed. Patients were divided into three groups based on morbidity (Group 1), mortality (Group 2), and no complication (Group 3).

Results

Of the 112 patients included in the study, morbidity was observed in 21 (18.8%), mortality in 11 (9.8%), and no complication was observed in 80 (71.4%), who were discharged with cure. The differences between group for the average values of the perforation diameter and American Society of Anesthesiologists, Acute Physiology and Chronic Health Evaluation II, and Mannheim Peritonitis Index scores were statistically significant (p<0.001 for each). The average values for the group with mortality were significantly higher than those of the other groups.

Conclusion

In this study where we investigated risk factors for increased morbidity and mortality in PUPs, there was statistically significant difference between the average values for age, body mass index, perforation diameter, and Acute Physiology and Chronic Health Evaluation II and Mannheim Peritonitis Index scores among the three groups, whereas the amount of subdiaphragmatic free air did not differ.

Low serum albumin may predict the need for gastric resection in patients with perforated peptic ulcer

PURPOSE

Perforated peptic ulcer (PPU) is a common surgical emergency and treatment involves omental patch repair (PR). Gastric resection (GR) is reserved for difficult pathologies. We audit the outcomes of GR at our institution and evaluate the pre-operative factors predicting the need for GR.

METHODS

This is a single-institution, retrospective study of patients with PPU who underwent surgery from 2004 to 2012. Demographics, clinical presentation and intra-operative findings were studied to identify factors predicting the need for GR in PPU. An audit of clinical outcomes and mortality for all patients with GR is reported.

RESULTS

537 (89.6 %) patients underwent PR and 62 (10.4 %) patients GR. Old age (p < 0.0001), female sex (p = 0.0123), non-steroidal anti-inflammatory drugs (NSAIDs) usage (p = 0.0008), previous history of peptic ulcer disease (PUD) (p = 0.0159), low hemoglobin (p < 0.0001), low serum albumin (p < 0.0001), high serum creatinine (p = 0.0030), high urea (p = 0.0006) and large ulcer size (p < 0.0001) predict the need for GR. On multivariate analysis only low serum albumin (OR 5.57, 95 % CI 1.56-19.84, p = 0.008) predicted the need for GR. The presence of Helicobacter pylori infection was protective against GR (OR 0.25, 95 %CI 0.14-0.44, p < 0.0001). Morbidity and mortality of GR was 27.7 and 24.2 %, respectively.

CONCLUSION

GR is needed in one in ten cases of PPU. Low serum albumin predicted the need for GR on multivariate analysis. Morbidity and mortality of GR remains high.

Prognostic factors in peptic ulcer perforations: a retrospective 14-year study

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

Impact of surgical delay on outcomes in elderly patients undergoing emergency surgery: A single center experience

AIM: To determine predisposing factors leading to surgical delay in elderly patients with acute abdominal conditions and its impact on surgical outcomes.

METHODS: A retrospective review of a total of 144 patients aged 60 years and older who had undergone emergency abdominal surgery between 2010 and 2013 at a regional general hospital was analysed. The operations analysed were limited to perforated or gangrenous viscus and strangulated hernia. Patient demographic features, time taken to obtain a computed tomography scan, time taken to surgery and the impact on postoperative morbidity and mortality were analysed.

RESULTS: The mean age was 70.5 ± 9.1 years and median time taken to surgery was 9 h. The overall mortality and complication rates (Clavien Dindo 3 and above) were 9% and 13.1% respectively. Diabetes mellitus was a significant predisposing factor which had an impact on surgical delays. Delays in surgery more than 24 h led to higher complication rates at 38.9% (P = 0.003), with multivariate analysis confirming it as an independent factor. Delays in obtaining a computed tomography (CT) scan was also shown to result in higher complication rates (Clavien Dindo 3 and above).

CONCLUSION: Delays in performing emergency surgery in elderly lead to higher complication rates. Obtaining CT scans early also may facilitate prompt diagnosis of certain abdominal emergencies where presentation is more equivocal and this may lead to improved surgical outcomes.

Abdominal emergencies in the geriatric patient

Abdominal pain is one of the most frequent reasons that elderly people visit the emergency department (ED). In this article, we review the deadliest causes of abdominal pain in this population, including mesenteric ischemia, abdominal aortic aneurysm, and appendicitis and potentially lethal non-abdominal causes. We also highlight the pitfalls in diagnosing, or rather misdiagnosing, these clinical entities.

Incidence and short-term mortality from perforated peptic ulcer in Korea: a population-based study

Background

Perforated peptic ulcer (PPU) is associated with serious health and economic outcomes. However, few studies have estimated the incidence and health outcomes of PPU using a nationally representative sample in Asia. We estimated age- and sex-specific incidence and short-term mortality from PPU among Koreans and investigated the risk factors for mortality associated with PPU development.

Methods

A retrospective population-based study was conducted from 2006 through 2007 using the Korean National Health Insurance claims database. A diagnostic algorithm was derived and validated to identify PPU patients, and PPU incidence rates and 30-day mortality rates were determined.

Results

From 2006 through 2007, the PPU incidence rate per 100 000 population was 4.4; incidence among men (7.53) was approximately 6 times that among women (1.24). Incidence significantly increased with advanced age, especially among women older than 50 years. Among 4258 PPU patients, 135 (3.15%) died within 30 days of the PPU event. The 30-day mortality rate increased with advanced age and reached almost 20% for patients older than 80 years. The 30-day mortality rate was 10% for women and 2% for men. Older age, being female, and higher comorbidity were independently associated with 30-day mortality rate among PPU patients in Korea.

Conclusions

Special attention should be paid to elderly women with high comorbidity who develop PPU.

Generalized peritonitis requiring re-operation after leakage of omental patch repair of perforated peptic ulcer

BACKGROUND/AIM

Peptic ulcer perforations are a common emergency, but available literature is silent on the exact definition, incidence, management, and complications of peritonitis due to omental patch leakage.

PATIENTS AND METHODS

Retrospective data were collected on 422 patients who underwent omental patch repair of perforated peptic ulcer between March 20, 1999 and March 20, 2006. The definitive diagnosis of perforated peptic ulcer and omental patch leakage was obtained at surgery.

RESULTS

Seventeen (4%) patients experienced generalized peritonitis due to omental patch leakage. Mean age was 60.6 years. Mortality rate was 29.4%, and the mean hospital stay was 23.6 days. Delay in surgical approach, shock on admission, and age were all significantly associated with increased mortality.

CONCLUSIONS

Peritonitis due to omental patch leakage can result in significant morbidity and mortality. The most common causes of omental patch leakage and operative procedures were unknown and reinsertion of omentum, respectively. Factors such as shock on admission or delayed surgery, have significantly contributed to fatal outcomes and need careful attention.

Perforation of peptic ulcer following abrupt cessation of long-term opiate use

PURPOSE

Unaided and abrupt cessation of opiate use without drug substitution and step-down, referred to as "cold turkey," is a common and difficult process for substance users, and is associated with several withdrawal symptoms and complications. This report presents a preliminary series of patients treated at an urban public hospital with acute perforation of peptic ulcers following abrupt cessation of long-term opiate use, a phenomenon that has not been previously described in the literature.

METHODS

Thirty-five patients with acute gastroduodenal perforation and a history of opiate addiction with a recent and abrupt cessation of opiate use were admitted between February 2004 and October 2008. This study evaluated the demographics, antecedent drug use, substance use characteristics, previous medical or surgical treatment of peptic ulcer disease, and surgical findings.

RESULTS

The mean age was 32.3 years (range, 21-41 years) and the patients were overwhelmingly male (94%). The most frequent agent in single opiate users was opium (62.9%) followed by heroin (22.9%). The time interval between opiate cessation and perforation onset was 2-65 days (mean, 6.1 days). All patients underwent an immediate exploratory laparotomy, and the majority of perforations were found to be in the postpyloric area (94%) with mean size of 4.3 x 5.1 mm. Two patients (6%) had perforations in the lesser curvature of the stomach.

CONCLUSION

All of the perforations occurred following sudden self-cessation without step-down or classic maintenance therapy, and this may prove the importance of supervised medical detoxification with special attention to gastroprotective agents such as antacid drugs.

Preoperative prognostic factors for mortality in peptic ulcer perforation: a systematic review

OBJECTIVE

Mortality and morbidity following perforated peptic ulcer (PPU) is substantial and probably related to the development of sepsis. During the last three decades a large number of preoperative prognostic factors in patients with PPU have been examined. The aim of this systematic review was to summarize available evidence on these prognostic factors.

MATERIAL AND METHODS

MEDLINE (January 1966 to June 2009), EMBASE (January 1980 to June 2009), and the Cochrane Library (Issue 3, 2009) were screened for studies reporting preoperative prognostic factors for mortality in patients with PPU. The methodological quality of the included studies was assessed. Summary relative risks with 95% confidence intervals for the identified prognostic factors were calculated and presented as Forest plots.

RESULTS

Fifty prognostic studies with 37 prognostic factors comprising a total of 29,782 patients were included in the review. The overall methodological quality was acceptable, yet only two-thirds of the studies provided confounder adjusted estimates. The studies provided strong evidence for an association of older age, comorbidity, and use of NSAIDs or steroids with mortality. Shock upon admission, preoperative metabolic acidosis, tachycardia, acute renal failure, low serum albumin level, high American Society of Anaesthesiologists score, and preoperative delay >24 h were associated with poor prognosis.

CONCLUSIONS

In patients with PPU, a number of negative prognostic factors can be identified prior to surgery, and many of these seem to be related to presence of the sepsis syndrome.

Risk factors in patients surgically treated for peptic ulcer perforation

OBJECTIVE

The overall mortality for patients undergoing surgery for perforated peptic ulcer has increased despite improvements in perioperative monitoring and treatment. The objective of this study was to identify and describe perioperative risk factors in order to identify ways of optimizing the treatment and to improve the outcome of patients with perforated peptic ulcer.

MATERIAL AND METHODS

Three hundred and ninety-eight patients undergoing emergency surgery in four university hospitals in Denmark were included in the study. Information regarding the pre-, intra- and postoperative phases were recorded retrospectively from medical records. Data were analysed using multiple logistic regression analysis. The primary end-point was 30-day mortality.

RESULTS

The 30-day mortality rate was 27%. The following variables were independently associated with death within 30 days of surgery: ASA (American Society of Anaesthesiologists) class, age, shock upon admission, preoperative metabolic acidosis, elevated concentration of creatinine upon admission, subnormal concentration of albumin upon admission and insufficient postoperative nutrition.

CONCLUSIONS

Thus, preoperative metabolic acidosis, renal insufficiency upon admission and insufficient postoperative nutrition have been added to the list of independent risk factors for death within 30 days of surgery in patients with peptic ulcer perforation. Finding that shock upon admission, reduced albumin blood levels upon admission, renal insufficiency upon admission and preoperative metabolic acidosis are independently related to 30-day mortality could indicate that patients with peptic ulcer perforation are septic upon admission, and thus might benefit from a perioperative care protocol with early source control and early goal-directed therapy according to The Surviving Sepsis Campaign. This hypothesis should be addressed in future studies.

Perforated peptic ulcer: how to improve outcome?

Despite the introduction of histamine H2-receptor antagonists, proton-pump inhibitors and the discovery of Helicobacter pylori, both the incidence of emergency surgery for perforated peptic ulcer and the mortality rate for patients undergoing surgery for peptic ulcer perforation have increased. This increase has occurred despite improvements in perioperative treatment and monitoring. To improve the outcome of these patients, it is necessary to investigate the reasons behind this high mortality rate. In this review we evaluate the existing evidence in order to identify significant risk factors with an emphasis on risks that are preventable. A systematic review including randomized studies was carried out. There are a limited number of studies of patients with peptic ulcer perforation. Most of these studies are of low evident status. Only a few randomized, controlled trials have been published. The mortality rate and the extent of postoperative complications are fairly high but the reasons for this have not been thoroughly explained, even though a number of risk factors have been identified. Some of these risk factors can be explained by the septic state of the patient on admission. In order to improve the outcome of patients with peptic ulcer perforation, sepsis needs to be factored into the existing knowledge and treatment.

Antipsychotic drugs and short-term mortality after peptic ulcer perforation: a population-based cohort study

BACKGROUND

Peptic ulcer perforation is a serious surgical emergency with a substantial short-term mortality, but the influence of antipsychotic drug use on the prognosis remains unknown.

AIM

To examine the association between antipsychotic drug use and 30-day mortality following peptic ulcer perforation.

METHODS

This cohort study comprised 2033 patients with a first-time hospitalization with peptic ulcer perforation, in Northern Denmark, between 1991 and 2004. Data on preadmission use of antipsychotics and other medications, psychiatric disease, other comorbidities and mortality were obtained through population-based medical databases. We used Cox regression analyses to compute adjusted mortality rate ratios (MRRs).

RESULTS

One hundred and sixteen (5.7%) patients with peptic ulcer perforation were current users of antipsychotic drugs at the time of hospital admission and 205 (10.1%) were former users. The overall 30-day mortality was 27%. Among current users of antipsychotics 30-day mortality was 39%. The adjusted 30-day MRR for current users of antipsychotic drugs compared with non-users was 1.7 (95% CI: 1.2-2.3). Former use was not a predictor of mortality. The increase in mortality was equal in users of conventional and atypical antipsychotics.

CONCLUSION

Use of antipsychotic drugs is associated with substantially increased mortality following peptic ulcer perforation.

Perforated peptic ulcer and short-term mortality among tramadol users

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT

* Use of nonsteroidal anti-inflammatory drugs (NSAIDs) is a strong risk and prognostic factor for peptic ulcer perforation, and alternative analgesics are needed for high-risk patients. * Pain management guidelines propose tramadol as a treatment option for mild-to-moderate pain in patients at high risk of gastrointestinal side-effects, including peptic ulcer disease. * Tramadol may mask symptoms of peptic ulcer complications, yet tramadol's effect on peptic ulcer prognosis is unknown.

WHAT THIS STUDY ADDS

* In this population-based study of 1271 patients hospitalized with peptic ulcer perforation, tramadol appeared to increase mortality at least as much as NSAIDs. * Among users of tramadol, alone or in combination with NSAIDs, adjusted 30-day mortality rate ratios were 2.02 [95% confidence interval (CI) 1.17, 3.48] and 1.32 (95% CI 0.89, 1.95), compared with patients who used neither tramadol nor NSAIDs.

AIM

Use of nonsteroidal anti-inflammatory drugs (NSAIDs) increases risk and worsens prognosis for patients with complicated peptic ulcer disease. Therefore, patients who are at high risk of peptic ulcer often use tramadol instead of NSAIDs. Tramadol's effect on peptic ulcer prognosis is unknown. The aim was to examine mortality in the 30 days following hospitalization for perforated peptic ulcer among tramadol and NSAID users compared with non-users.

METHODS

The study was based on data on reimbursed prescriptions and hospital discharge diagnoses for the 1993-2004 period, extracted from population-based healthcare databases. All patients with a first-time diagnosis of perforated peptic ulcer were identified, excluding those with previous ulcer diagnoses or antiulcer drug use. Cox regression was used to estimate 30-day mortality rate ratios for tramadol and NSAID users compared with non-users, adjusting for use of other drugs and comorbidity.

RESULTS

Of 1271 patients with perforated peptic ulcers included in the study, 2.4% used tramadol only, 38.9% used NSAIDs and 7.9% used both. Thirty-day mortality was 28.7% overall and 48.4% among users of tramadol alone. Compared with the 645 patients who used neither tramadol nor NSAIDs, the adjusted mortality rate in the 30 days following hospitalization was 2.02-fold [95% confidence interval (CI) 1.17, 3.48] higher for the 31 'tramadol only' users, 1.41-fold (95% CI 1.12, 1.78) higher for the 495 NSAID users and 1.32-fold (95% CI 0.89, 1.95) higher for the 100 patients who used both drugs.

CONCLUSION

Among patients hospitalized for perforated peptic ulcer, tramadol appears to increase mortality at a level comparable to NSAIDs.

30-day mortality after peptic ulcer perforation among users of newer selective COX-2 inhibitors and traditional NSAIDs: a population-based study

OBJECTIVES

Nonsteroidal anti-inflammatory drug (NSAID) use is a strong risk factor for peptic ulcer perforation, yet little is known about the outcome of this condition among NSAID users. We examined 30-day mortality after peptic ulcer perforation associated with the use of traditional NSAIDs and newer selective cyclo-oxygenase-2 (COX-2) inhibitors.

METHODS

We conducted a cohort study of patients with the first hospitalization for peptic ulcer perforation, identified in discharge registries of three Danish counties between 1991 and 2003. Data on preadmission NSAID use, other ulcer-related drugs, and comorbidity were likewise from population-based registries. Mortality was ascertained from the Civil Registration System. We compared 30-day mortality in NSAID users and nonusers while adjusting for age, gender, comorbidity, previous uncomplicated peptic ulcer, and ulcer medication use.

RESULTS

Of the 2,061 patients hospitalized with peptic ulcer perforation, 38% were current NSAID users. The 30-day mortality was 25% overall, and 35% among current NSAID users. Compared with never-use, the adjusted 30-day mortality rate ratios (MRRs) were 1.8 (95% CI 1.4-2.3) for current use of NSAIDs alone and 1.6 (95% CI 1.2-2.2) for current use combined with other ulcer-associated drugs. The mortality increase associated with the use of COX-2 inhibitors was similar to that of traditional NSAIDs: adjusted MRR for users of COX-2 inhibitors alone and in combination, 2.0 (1.3-3.1) and 1.4 (0.8-2.5), and for users of traditional NSAIDs alone or in combination, 1.7 (1.3-2.3) and 1.6 (1.2-2.3).

CONCLUSION

Current use of NSAIDs, including COX-2 inhibitors, is associated with a poor prognosis for patients hospitalized with peptic ulcer perforation.

[Ulcer surgery - what remains?]

Ulcer surgery today concentrates on the complications of chronic ulcer disease, especially ulcer perforation and endoscopically uncontrollable ulcer bleeding. In this case the laparoscopic or open closure of the gastroduodenal defect or local hemostasis of the bleeding ulcer by laparotomy are the main aims of surgery. Elective operations due to recurrent gastric or duodenal ulcers have become rare. An indication for gastric ulcer resistant to conservative therapy could be persisting suspicion of malignancy whereas in duodenal ulcer gastric outlet obstruction represents a reason for surgery. If these indications are confirmed the classic procedures of gastric resection like Billroth I and Billroth II are performed whereas vagotomy is no longer used. Altogether ulcer surgery has become very safe although it is practiced quite rarely.

Abdominal Pain in the Elderly

Elderly patients who have abdominal pain remain one of the most challenging patient populations. Signs and symptoms of serious disease are often nonspecific. Atypical presentations are common in elderly patients. In addition, the higher incidence of serious pathology in this population requires emergency physicians to be vigilant and thorough in their work-up. Vascular catastrophes are more likely to be seen in this population, and a broad differential diagnosis needs to be considered.

Peritonitis - the Eastern experience

Peritonitis is a common emergency encountered by surgeons the world over. This paper aims to provide an overview of the spectrum of peritonitis seen in the East. Studies dealing with the overall spectrum of secondary peritonitis in various countries of this region were identified using Pubmed and Google. These were analyzed for the site and cause of perforation and the mortality. It was observed that perforation of duodenal ulcers was the most the commonly encountered perforations. These are followed by small bowel and appendicular perforations. Colonic perforations were uncommon. The overall mortality ranges between 6–27%.

Perforated peptic ulcer: use of pre-admission oral glucocorticoids and 30-day mortality

BACKGROUND

Despite evidence that use of glucocorticoids increases the risk of complicated peptic ulcer disease, limited data exist on how use of oral glucocorticoids affects outcome for patients with peptic ulcer perforation.

AIM

To examine 30-day mortality from peptic ulcer perforation among pre-admission oral glucocorticoid users compared with non-users.

METHODS

We identified 2061 patients with a first-time hospital discharge diagnosis of perforated peptic ulcer, using population-based discharge registries in three Danish counties. Data on use of glucocorticoids and other ulcer-related drugs, previous hospitalizations for uncomplicated peptic ulcer disease, and comorbidity were obtained from discharge registries and prescription databases. Follow-up data on mortality were provided by the Danish Civil Registry System.

RESULTS

A total of 228 patients (11.1%) were exposed to glucocorticoids within 60 days of admission. Overall 30-day mortality rate was 25.2%, the corresponding rate among current glucocorticoid users was 39.4%. Compared with 'never users', the adjusted mortality ratio among current users of oral glucocorticoids alone was 2.1 (95% CI: 1.5-3.1). Among current users of oral glucocorticoids in combination with other ulcer-related drugs the mortality ratio was 1.5 (95% CI: 1.1-2.1).

CONCLUSION

Pre-admission use of oral glucocorticoids is associated with up to a twofold increase in 30-day mortality among patients hospitalized with perforated peptic ulcer.

Abdominal surgical emergencies in the elderly

The evaluation of abdominal pain can be considerably more challenging in elderly patients. A higher likelihood of life-threatening pathology combined with a myriad of diagnostic pitfalls in this population mandate a more cautious approach with greater use of diagnostic resources and specialist consultation.

Significant factors associated with fatal outcome in emergency open surgery for perforated peptic ulcer

AIM: To evaluate the main factors associated with mortality in patients undergoing surgery for perforated peptic ulcer referred to an academic department of general surgery in a large southern Italian city.

METHODS: One hundred and forty-nine consecutive patients (M:F ratio = 110:39, mean age 52 yrs, range 16-95) with peptic ulcer disease were investigated for clinical history (including age, sex, previous history of peptic ulcer, associated diseases, delayed abdominal surgery, ulcer site, operation type, shock on admission, postoperative general complications, and intra-abdominal and/or wound infections), serum analyses and radiological findings.

RESULTS: The overall mortality rate was 4.0%. Among all factors, an age above 65 years, one or more associated diseases, delayed abdominal surgery, shock on admission, postoperative abdominal complications and/or wound infections, were significantly associated (χ²) with increased mortality in patients undergoing surgery (0.0001 < P < 0.03).

CONCLUSION: Factors such as concomitant diseases, shock on admission, delayed surgery, and postoperative abdominal and wound infections are significantly associated with fatal outcomes and need careful evaluation within the general workup of patients admitted for perforated peptic ulcer.

Preoperative sonographic diagnosis of sealed-off perforated gastric ulcer

Perforated peptic ulcer (PPU) is a common surgical emergency. Early diagnosis and intervention are necessary to reduce the morbidity and mortality. Radiographic or sonographic detection of free air is neither sensitive nor specific for PPU. We report a case of sealed-off PPU with direct sonographic demonstration of the perforation tract within the anterior wall of the gastric antrum. The diagnosis was confirmed at laparotomy.
