The Geriatric Acute Abdomen

Investigation of Geriatric Patients with Abdominal Pain Admitted to Emergency Department

INTRODUCTION

The aim of this study is to detect the possible reasons of abdominal pain in the patients aged 65 and older admitted to emergency department (ED) with complaint of abdominal pain which is not related to trauma, to determine the length of hospitalization of old (65-75 age) and elderly (aged 75 and older) patients, and to define the hospitalization and mortality rates.

MATERIAL AND METHODS

In the study, 336 patients were included. Groups were compared in respect to gender, internal or surgical prediagnoses, complaints accompanying abdominal pain, vital findings, comorbidities, requested consultations, hospitalizing service, waiting time in the ED and in the hospital, and treatment methods.

RESULTS

Of the patients, 48.2% were male, and 51.8% were female. While 52.4% of the patients were in 65-74 age group, 47.6% of them were aged 75 years and above. An internal disease was detected in 76.8% of the patients as an origin of abdominal pain. Most common prediagnoses were biliary diseases and diseases related to biliary tract followed by nonspecific abdominal pain, abdominal pain secondary to malignity, ileus, and acute gastroenteritis, respectively. The most frequent finding accompanying abdominal pain was vomiting. The most frequent chronic disease accompanying abdominal pain was hypertension in both age groups. We observed that 75.9% of the patients required consultation. We detected that 48.8% of the patients with abdominal pain were hospitalized and they were hospitalized mostly by gastroenterology ward (24.8%). Surgical treatments were applied to the 17.6% of the patients with abdominal pain.

CONCLUSION

Clinical findings become indistinct by age, and differential diagnosis of abdominal pain gets more difficult in geriatric patients. Therefore, physicians should consider age related physiological changes in order to distinguish geriatric patients admitted to emergency service with abdominal pain from pathological cases requiring immediate surgical operation.

Abdominal Pain in the Geriatric Patient

Abdominal pain in the elderly can be a challenging and difficult condition to diagnose and treat. The geriatric population has significant comorbidities and often takes polypharmacy that can mask symptoms. The presentation of common conditions can be different than that in the younger population, often lacking the traditional indicators of disease, making it of pivotal importance for the clinician to consider a wide differential during their workup. It is also important to consider extra-abdominal abnormality that may manifest as abdominal pain.

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.

The acute abdomen in the older person

The acute abdomen is a common condition in older people. Half of all presentations to hospital require admission, with a third requiring immediate surgery. The Royal College of Surgeons of England have reported a worryingly high mortality rate in the over 80s undergoing emergency surgery, with a 3-fold difference in mortality throughout the England, Wales and Northern Ireland. The aim of this article is to highlight the issues that older people face in relation to acute abdominal pathology.

Acute abdominal pain in the older adult

Abdominal pain in older adults is a concerning symptom common to a variety of diagnoses with high morbidity and mortality. Organizing the differential into categories based on pathology (inflammatory, obstructive, vascular, or other causes) provides a framework for the history, physical, and diagnostic studies. An organized approach and treatment and considerations specific to the geriatric population are discussed.

Laparoscopic appendectomy is safe and efficacious for the elderly: an analysis using the National Surgical Quality Improvement Project database

BACKGROUND

Despite increasing use of laparoscopic appendectomy, data demonstrating outcomes of this technique exclusively among the elderly population are scarce. This study aimed to compare 30-day postoperative morbidity and length of hospital stay among elderly patients after appendectomy.

METHODS

Appendicitis patients older than 65 years were extracted from the National Surgical Quality Improvement Project (NSQIP) database. Demographics and rates of complications for patients undergoing open and laparoscopic appendectomies were compared. Uni- and multivariate analyses adjusted for differences between groups compared the end points of major and minor complications as well as the days of hospital stay after initial surgery.

RESULTS

A total of 3,335 patients underwent appendectomy, with 2,235 patients (67%) receiving a laparoscopic procedure. The open appendectomy patients were significantly older and more likely to have various preoperative comorbidities (p<0.05). No difference in median operative time between the two techniques was found. Both required 51 min (p=0.11). The open cases had higher rates of both major and minor postoperative complications than the laparoscopic cases (p<0.0001), both overall and before discharge. Multivariate analysis showed no association between operative approach and major complications, and a reduced risk of minor complications with laparoscopy. Length of surgical stay was longer for the open group than for the laparoscopically treated group (median, 4 days vs 2 days; p<0.05). After adjustment, laparoscopy still was significantly associated with a shorter hospital stay than open appendectomy (p<0.0001).

CONCLUSIONS

Laparoscopic appendectomy is a safe procedure for elderly patients. During the 30-day postoperative period, no correlation with major complications was found, and the findings showed a beneficial association with regard to minor complications. After adjustment for perioperative factors, laparoscopy is associated with a shorter hospital stay than open appendectomy.

Abdominal Pain

Evaluation of the elderly patient with acute abdominal pain is sometimes difficult. Various factors can obscure the presentation, delaying or preventing the correct diagnosis and leading to adverse patient outcomes. Clinicians must consider multiple diagnoses, especially those life-threatening conditions that require timely intervention to limit morbidity and mortality. This article reviews abdominal pain in the elderly, discusses the clinical approach, and highlights key diagnostic considerations.

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.

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.

Abdominal pain in geriatric emergency patients: variables associated with adverse outcomes

OBJECTIVE

To determine the diagnoses and outcomes of geriatric patients with abdominal pain, and to identify variables associated with adverse outcomes.

METHODS

Geriatric emergency patients (aged 65 years and older) with a complaint of abdominal pain were participants in this longitudinal case series. Eligible patients were followed by telephone contact and chart review, to determine outcomes and final diagnoses.

RESULTS

Of 380 eligible patients, follow-up information was available for 375 (97%), for the two months following the ED visit. Final diagnoses included infection (19.2%), mechanical-obstructive disorders (15.7%), ulcers/hypersecretory states (7.7%), urinary tract disease (7.7%), malignancy (7.2%), and others. Although 5.3% of the patients died (related to presenting condition), most (61.3%) patients ultimately recovered. Surgical intervention was required for 22.1% of the patients. Variables associated with adverse outcomes (death, and need for surgical intervention) included hypotension, abnormalities on abdominal radiography, leukocytosis, abnormal bowel sounds, and advanced age. Most physical examination findings were not helpful in identifying patients with adverse outcomes. This study demonstrated a higher incidence of malignancy (7.2%) and a lower incidence of disease necessitating surgical intervention (22.1%) than previously reported.

CONCLUSIONS

The majority of geriatric emergency patients with abdominal pain have significant disease necessitating hospital admission. Morbidity and mortality among these patients are high, and specific variables are strongly associated with death and the need for surgical intervention. Absence of these variables does not preclude significant disease. Physical examination findings cannot reliably predict or exclude significant disease. These patients should be strongly considered for hospital admission, particularly when fever, hypotension, leukocytosis, or abnormal bowel sounds are present.

Emergency department evaluation of geriatric patients with acute cholecystitis

OBJECTIVE

To estimate the frequency of abnormal clinical symptoms, laboratory tests, and diagnostic imaging studies in the ED assessment of elderly (> or = 65 yr) patients with acute cholecystitis, and to compare these factors in young-old (65-74 yr), middle-old (75-84 yr), and old-old (> or = 85 yr) population groups.

METHODS

A retrospective, cross-sectional study was performed by review of ED records, hospital charts, and surgical operative reports of consecutive elderly ED patients determined at surgery to have acute cholecystitis. Records were reviewed between April 1990 and April 1995 at a large Midwestern tertiary care facility with 65,000 annual ED patient visits. Clinical signs and symptoms were compared in the young-old, middle-old, and old-old population groups.

RESULTS

Of the 168 patients reviewed, 141 (84%) had neither epigastric or right upper quadrant abdominal pain, and 8 (5%) had no pain whatsoever. Only 61 patients (36%) had back or flank pain radiation. Ninety-six (57%) experienced nausea, 64 (38%) had emesis, and 13 (8%) had visible jaundice. Ninety-four (56%) patients were afebrile and 69 (41%) had no increase of white blood cell count. Twenty-two (13%) patients had no fever and all tests were normal. No statistical difference was noted in any symptom or laboratory factor for the 3 age groups, except jaundice was more common among the patients aged > or = 85 years. Ultrasonography was diagnostic for 91%, and CT was beneficial for only 1 patient. Eight patients had normal results on their ultrasonographic and CT studies.

CONCLUSION

Classic symptoms and abnormal blood test results are frequently not present in geriatric patients with acute cholecystitis. Increasing age does not appear to affect the clinical and test markers used by clinicians to diagnose this illness. A high degree of awareness is essential for correct diagnosis of acute cholecystitis in geriatric patients.

Evaluation of abdominal pain in the elderly

Evaluation of the older patient presents a unique challenge to the emergency physician. The increased age of the population, a high incidence of comorbidity, general poverty of history and clinical signs in acute abdominal conditions, poor reliability of diagnostic procedures, and the variable presentations of diseases with significant morbidity and mortality summarize the problems to be encountered with the complaint of abdominal pain in the elderly. The correct diagnosis is often difficult to establish and coexisting complicating diseases influence the patient's condition and the ED management. The emergency physician must maintain a wide differential and have a low threshold for admission and more extensive evaluation in this patient population.
