Sonographic Findings In Patients With Non Traumatic Upper Abdominal Pain At Ket Medical Services And Life Chart Scanning Centre Enugu, Nigeria

This research was aimed at evaluating the usefulness of ultrasonography in the diagnosis and management of upper abdominal pain. A retrospective study was done at Ket Medical Services   and Life chart Scanning Centre Abapka, Enugu. A total of 236 patients that were scanned for upper abdominal pain from March, 2011 to March, 2012 were studied. The sonographic reports showed that Fatty liver is the highest sonographic findings in patients with upper abdominal pain with a total number of 41 (17.37%), followed by   hepatitis 36(15.25%),pyelonephritis 30(12.71%), hydronephrosis 19(8.05%), Splenomegaly 14(5.93%), 10(4.23%) each for cholecystitis and normal studies, 9 (3.81%) each for schistosomiasis and PUD, renal stone 8(3.38%), glomerulonephritis 7(2.96%), renal failure 4(1.69%), pancreatitis 3(1.27%), gall bladder sludge 2(0.88%), 1(0.42%) each for multiple hepatic cyst, haepatoma ,liver mass and poly cystic kidney. It was also found that 31-35years age group was mostly affected with upper abdominal pain and 0-5 years age group was the least affected. Finally, the incidence of upper abdominal pain was greater in female than in male.

Abdominal ultrasound is a rapid and non-invasive method of examination of the abdomen. Abdominal ultrasound is an imaging procedure used to examine the internal organs of the abdomen including the liver, gallbladder, spleen pancreas and kidney.  The blood vessels that lead to some of these organs can also be looked at with ultrasound.

 Abdominal pain is the most frequent reasons for abdominal scan.  Ultrasound is one of the non- invasive modalities used for the investigation of patient with abdominal pain.  Upper abdominal pain is one of the commonest complaints in patients seeking medical advices.

 Upper abdominal ultrasound can reveal many possible conditions including abdominal aortic aneurysm, abscess, cholecystitis, gall stone, hydronephrosis, kidney stones, splenomegaly and pancreatitis.

 In preparation for ultrasound of the liver, gallbladder or digestive tract, the patient will be asked to fast overnight or for at least six hours prior to the test, which reduces bowel gas that can obscure the image and keeps the gallbladder filled with bile, making it easier to visualize its contents. In examination involving stomach and duodenum, the patient will be given water to drink immediately before the test because these organs are better visualized if there are filled with fluids4.  Abdominal pain may not come from the abdomen; some surprising causes include heart attacks and pneumonias.

 The location of the pain within the abdomen can be an important clue in diagnosis during scanning5.  Symptoms that occur with upper abdominal pain include back pain, chest pain, constipation, diarrhea, fever, nausea and vomiting. 

 Upper abdominal pain can be acute or chronic.  Upper abdominal pain whether acute or chronic is caused by diseases of the liver, gallbladder kidneys pancreas, stomach, duodenum, spleen, pleura pericardium and basal lung segments. The characteristics of the pain, location and timing duration etc are Important in diagnosing its causes. All these conditions have useful sonographic features which help in their diagnosis except uncomplicated peptic ulcer disease acute myocardial infarction and pneumonitis.

 The frequency with which even relatively inexpensive and non-invasive diagnostic tests are performed clearly places a burden on healthcare.  Therefore, it is important that their influence on patient management is assessed.  Unnecessary diagnostic investigation may lead to incidental findings or to additional unnecessary diagnostic procedures or even over treatment
