2. Objectives :
● To explain and demonstrate the history
taking for patients with abdominal mass
● To demonstrate the physical diagnosis in
patients with abdominal mass
● To explain investigative studies for abdominal
mass
● To discuss the decision making for the
management of abdominal mass
3. Introduction
● Why is it important?
● Abdominal masses
● are commonly addressed by surgeons,
● cover a broad spectrum: no apparent
consequences, others significantly impair quality
of life, others represent severe conditions
● For each patient, therefore, it is essential to formulate a
management approach that is tailored to the particular
clinical situation.
4. Introduction
● Commonly, an abnormal enlargement or mass in
the abdomen comes to the clinician's attention
in one of three ways:
● detected and reported by the patient,
● discovered by the clinician on physical
examination,
● noticed as an unrelated incidental finding on
a radiographic study.
5. Introduction
● Effective decision-making involves:
● establishing the correct diagnosis,
● introducing an effective treatment plan,
● eliminating risks and complicating factors,
● initiating preventive measures,
● determining the prognosis.
6. Definition
● Palpable mass that lies anterior to the paraspinous
muscles in a region bordered by the costal margins,
the iliac crests, and the pubic symphysis.

8. History taking
● Establishing a solid surgeon-patient relationship is
vital for building patient trust and confidence,
● philosophy in dealing with an abdominal mass is:
● to evaluate the patient
● consider radiographic and laboratory studies if
the initial assessment does not yield a diagnosis.
10. Patient Identity
» Ask the patient politely concerning his/her:
name age
» Record the gender:
– Male
– Female
» Ask the marital status of the patient (especially for
female)
11. Current history of illness
● A careful and methodical clinical history
should be taken that includes all factors
pertaining to the lesion.
● Ask concerning the mass (non directive):
● mode of onset, duration, character,
chronology, and location.
● Presence or absence of associated
symptoms.
12. History
● Associated GI symptoms with the mass:
● concerned with nausea
● vomiting,
● diarrhea,
● constipation
● Non specific GI symptoms
● jaundice, melena, hematochezia, hematemesis,
hematuria, or changes in stool caliber
13. History
● Non-GI symptoms
● urologic, gynecologic or obstetric,
vascular, and endocrinologic symptoms
● A history of surgery, trauma, or neoadjuvant
or adjuvant cancer therapy.
16. Physical Diagnosis
● Practice in examining patients with an
abdominal mass is to follow an
organized, systematic approach
consisting of:
● inspection,
● auscultation,
● percussion, and
● palpation,
17. Physical Diagnosis
● Three main objectives:
● evaluate the patient's condition as it directly or
indirectly relates to the mass (e.g., by noting
associated systemic illness, pain, malaise, or cachexia)
● assess the acuteness of the patient's condition (e.g.,
by determining whether a left upper quadrant mass is
likely to be a ruptured spleen or simply a long-
standing mass in the abdominal wall)
● must carefully examine each abdominal quadrant,
assessing both normal and abnormal anatomic
relations as possible sources of the presumed mass.
18. Physical Diagnosis
● General examination should seek systemic signs
of disease (e.g. cachexia, anaemia and jaundice)
or signs of malignant dissemination (e.g.
supraclavicular lymphadenopathy in suspected
stomach cancer).
● Abdominal and pelvic examination must be
thorough and, if appropriate, proctoscopy and
sigmoidoscopy should be performed.
21. Physical Diagnosis
● Determine (Inspection, Palpation, Percussion)
● The location of the mass, its relations to other structures,
● Mobility
● Physical characteristics, such as size, shape, consistency
and pulsatility (information: organ of origin and the likely
pathology).
● Hernias, e.g. incisional, umbilical and sometimes interstitial
(Spigelian) hernias (see Ch. 32), may present as localised
swellings but they usually shrink or reduce completely
when the patient is supine or under anaesthesia.
● An incarcerated (irreducible but not obstructed) hernia is
more appropriately considered a true 'mass'.
22. Physical Diagnosis
● Palpable or discrete masses should always be localized
(abdominal land marks) , and described :
● terms of size, shape, consistency, contour, presence or
absence of tenderness, pulsatility, and fixation
● The mass's location can be vaguely outlined: fluid is present,
the abdomen is tender or tense, the patient is obese.
● Gastric neoplasms, pancreatic neoplasms, colonic neoplasms,
sarcomas, pancreatic cysts, and distended gallbladders are
palpable (adsvanced stages) and recognition can be facilitated
by repeating the abdominal examination after analgesics have
been administered or after the patient has been anesthetized in
preparation for a procedure.
23. Working or Presumed Diagnosis
» generate a working diagnosis.
» Consider subsequent management
» Sometimes, however, the diagnosis remains unknown
even after a comprehensive clinical history and physical
examination; in such cases, further studies are required.
» Investigative methods: A wide range of laboratory and
imaging studies are now available for establishing the
diagnosis.
» If these studies do not resolve the diagnostic uncertainty,
additional procedures, including image-guided
percutaneous biopsy, diagnostic laparoscopy, and
exploratory laparotomy, may be employed as necessary.
24. Investigative Studies
» Collaborative management effort and the
choice of appropriate investigative studies.
» Be familiar with every available method for
efficient and cost-effective diagnosis of an
abdominal mass.
» Be based on:
– the preferences of the patient,
– the knowledge and judgment of the
surgeon, and the capabilities of the
institution
