Acute Abdomen
• Be defined generally as an intra abdominal process causing severe pain and often requiring surgical intervention.
![Page 6: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/6.jpg)
Acute AbdomenAcute conditions of the abdomen are produced by : congenital inflammatory obstructive trauma vascular mechanisms or high intra abdominal pressure
manifested by sudden onset of abdominal pain, gastrointestinal symptoms and varying degrees of local and systemic reaction.

Where is the pain ?
Question No.1 :
It is important to know :The originThe locationRadiation and Character of abdominal pain
in order to understand its significance.
![Page 12: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/12.jpg)
Characteristics of the Acute Abdomen
• Since pain is the most prominent presenting complaint in a patient with an acute abdomen,
• The perception of abdominal pain is first visceral and then becomes somatic.
![Page 13: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/13.jpg)
Pathophysiology • Visceral pain :– Distention, inflammation or
ischaemia in hollow viscous & solid organs
– Localisation depends on the embryologic origin of the organ:
• Forgut to epigastrium• Midgut to umbilicus• Hindgut to the
hypogastric region• Parietal pain :
– is localised to the dermatome above the site of the stimulus.
• Referred pain :– produces symptoms, not
signs e.g. tenderness

Does the pain travel to any other part of the body ?
![Page 16: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/16.jpg)
Question No. 2 :What is the pain like ?
• Acute waves of sharp constricting pain that “take the breath away” renal or biliary colic
• Waves of dull pain with vomiting intestinal obstruction• Colicky pain that becomes steady appendicitis, strangulating
intestinal obstruction, mesenteric ischemia• Sharp, constant pain, worsened by movement peritonitis• Tearing pain dissecting aneurysm• Dull ache initial epigastric pain in appendicitis, diverticulitis,
pyelonephritis• Aching pelvic inflammatory disease • Pleuritic intensified by breathing • Lancinating acute pancreatitis
![Page 17: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/17.jpg)
Classic Appendicitis
• Patient presents initially with vague peri-umbilical pain with associated nausea and vomitting due to distention of the appendix (visceral peritoneum).
• Followed by localized RLQ pain due to progression of inflammation to parietal peritoneum.
Infected Appendix and Fecolith

If the answer is “Yes” suggests recurrent problems such as ulcer disease, gallstone colic or diverticulitis.
Question No. 3 :Have you had it before ?
Question No. 4 :Was the onset sudden ?• Yes, Sudden : “like a light switching on”
(perforated ulcer, renal stone, ruptured ectopic pregnancy, torsion of ovary or testis, some ruptured aneurysms).
• No, Less sudden : most other causes (gradual pain mesenteric thrombosis)
![Page 23: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/23.jpg)
Question No. 5 :How severe is the pain (intensity of the pain) ?
• Severe pain (perforated viscus, kidney stone, peritonitis, pancreatitis)
• Moderate appendicitis • Pain out of proportion to physical findings (mesenteric
ischemia)
Gaster Perforation
Kidney Stone
Ureter Stone
![Page 24: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/24.jpg)
Question No.6 :What is the temporal features of the pain ?
• Continuous - acute pancreatitis • Pulsatile - abdominal aneurysm • Colicky - lumen obstruction, intermittent
severe pain with pain-free intervals
Frequency & duration transient pain of short duration which does not recur is usually insignificant.
The longer the duration the more likely a surgical condition.
![Page 25: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/25.jpg)
Question No. 7 :What other symptoms occur with the pain?
• Vomiting precedes pain and is followed by diarrhea (gastroenteritis).
• Delayed, repeated vomiting, absent bowel movement and flatus, large amounts, often bile stained and may become fecal (acute intestinal obstruction; the delay increases with a lower site of obstruction).
![Page 26: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/26.jpg)

Question No. 8 :What are the factors which may intensify or relieve pain ?
• Relation to meals - peptic ulcer pain relieved by food. Cholecystitis pain aggravated by fatty meal.
• Posture jack-knifing leg drawn up, to decrease peritoneal irritation in suppurative appendicitis.
• Motion - any movement causes intense pain in generalized peritonitis and the patient lies motionless.
![Page 30: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/30.jpg)
• Diarrhea most common with acute gastroenteritis or food poisoning, but it may occur with appendicitis or other focal inflammatory lesions of the gut
• Constipation or obstipation – Complete small bowel obstruction -
unrelenting constipation (obstipation) after fecal material below obstruction has been passed.
– Progressive constipation with carcinoma of the large bowel.
• Gas stoppage with decreased or absent bowel sounds - paralytic ileus

Patient's Symptoms
• All of the patient's symptoms must be carefully considered and analyzed, especially with regard to organs most likely to give rise to acute conditions.
• Extra-abdominal conditions which simulate the acute abdomen arise most often in the heart, lungs, urinary tract and female reproductive organs.

Action on Acute Abdomen
• Require immediate surgery• Require watchful expectancy, • Require medical rather than surgical management
• Often the patient's condition is such that extensive laboratory investigation requiring many hours would compromise the patient's life.
• The outcome often depends on a precise and detailed history and physical examination.
![Page 62: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/62.jpg)
Surgical Interventions
• Surgical intervention is mandatory in : Severe abdominal pain in patients who have
been fairly well, and which persists as long as six hours.
Persistent localized tenderness with muscle spasm, indicative of localized peritoneal inflammation The tenderness may be best determined by rectal or pelvic exam.
Characteristic, severe, intermittent cramping, colicky pain, with obstruction of a hollow viscus.
![Page 63: Recent Updates in Acute Abdomen Management DR. Dr. Toar JM Lalisang, SpB(K)BD Digestive Surgery Division – Department of Surgery Faculty of Medicine, University.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649f355503460f94c526d9/html5/thumbnails/63.jpg)
Surgical Case• Markedly hyperactive bowel sounds with
small intestinal obstruction, or decreased to absent bowel sounds with paralytic ileus.
• Paralytic ileus not secondary to other abdominal pathology is treated nonsurgically.
• Paralytic ileus as an end-result of mechanical small bowel obstruction or perforated duodenal ulcer requires surgical intervention to relieve the underlying pathology.

• Repeated vomiting of copious amounts of bile-stained or fecal material - in small bowel obstruction.
• Palpation of a mass : In RLQ or RUQ intussusception. Adnexal mass by pelvic exam ectopic pregnancy. Tender and thickened adnexae by pelvic PID. An irreducible incarcerated inguinal hernia. A tender RLQ mass by abdominal palpation or rectal
exam appendiceal abscess.

Blunt Abdominal TraumaMechanisms• Direct impact• Acceleration-deceleration
forces• Shearing forces
• No correlation between size of contact area and resultant injuries.
• Abdomen = potential site of major blood loss.

Role of Diagnostic Laparoscopy
• Hemodynamically stable patients• Inadequate/equivocal FAST or borderline
DPL (80K-120K RBC/HPF)• Intermittent mild hypotension or persistent
tachycardia• Persistent abdominal signs/symptoms• Potential to decrease numbers of
nontherapeutic laparotomies (negative laparotomy)

Penetrating Abdominal Trauma
Evaluation of Stab Wounds• Local exploration• DPL
– 5cc gross blood on aspiration– >20K RBC/mm3– >500 WBC/mm3– >175U amylase/100mL– Bacteria– Bile, Food particles
• CT– Limited ability to dx hollow organ
injury– Useful for posterior SW
• FAST
– Limited, high false negative rate
– Useful for pericardial injuries
• Diagnostic laparoscopy
– Useful for assessing peritoneal penetration, diaphragm injury
– Shorter LOS than negative laparotomy
