31
Temperature in General Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Normal or Slight rise of temperature (37.2 - 38 degree C). N.B : High fever arouses suspicion of peritonitis or abscess formation.
32
Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
(1) Localized tenderness at McBurney's point. (2) Rebound tenderness at McBurney's point : (3) Rovsing's sign (4) Blumberg's sign (5) Sherren's triangle of hyperaesthesia : (6) Baldwing's sign
33
place of McBurney's point
At the junction of the medial 2/3 and lateral 1/3 of a line between ASIS and umbilicus
34
Rebound tenderness at McBurney's point in Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Pain exaggerated over McBurney's point on sudden | release of pressure by the hand or coughing
35
Rovsing's sign in Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Crossed tenderness * Pressure on left iliac fossa causes pain felt in right iliac fossa (due to displacement of the gas inside the colon to caecum distending it & appendix, exaggerating the pain). * Not present in every case.
36
Blumberg's sign in Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Crossed rebound tenderness Indicate pelvic peritonitis rebound tenderness on both sides
37
Sherren's triangle of hyperaesthesia in Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
It is triangle bounded by symphysis pubis, umbilicus & A.S.I.S.
38
Baldwing's sign in Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Straight leg raising sign Raising straight the Rt. L.L causes pain due to pressure on the Rt. Iliac fossa.
39
Muscle guarding or rigidity over right iliac fossa denotes
Appendicular mass or abscess or perforation is about to occur, or has occurred.
40
Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
(1) Long retrocaecal appendix : (2) Pelvic appendicitis: (3) Subhepatic appendicitis : (4) Postileal appendicitis :
41
Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Tenderness over the right iliac fossa If the appendix is in relation to ureter If appendix is in contact with the psoas muscle (Psoas sign)
42
Tenderness over the right iliac fossa in Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
may be minimal and elicited on deep palpation.
43
If the appendix is in relation to ureter in Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
pain simulating ureteric colic will be misleading.
44
Psoas sign in Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
* If appendix is in contact with the psoas muscle, psoas spasm may be sufficient to cause flexion of the hip joint. * Extension of the hip causes abdominal pain.
45
Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Symptoms related to the rectum or to the bladder Tenderness Zachary Cope sign :
46
Symptoms related to the rectum or to the bladder in Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
symptoms related to the rectum as tenesmus & diarrhea symptoms related to the bladder as frequency of micturation
47
Tenderness in Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Absence of tenderness over McBurney's point. Tenderness can be elicited on P.R. & P.V.
48
Zachary Cope sign in Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
* If the appendix is in relation to the obturator internus muscle, spasm of the muscle causes flexion & external rotation of the hip. * So internal rotation of the flexed thigh will cause abdominal pain.
49
Subhepatic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Picture of acute cholecystitis
50
Postileal appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
* Diarrhea. | * Portal pyaemia.
51
Pathogenesis of Diarrhea in Postileal appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Due to irritation ~~ mucus secretion
52
Pathogenesis of Portal pyaemia in Postileal appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS
Thrombophlebitis of iliocolic vein of the ileocolic vein leading to portal pyaemia.
53
Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
1. Acute appendicitis in children 2. Acute appendicitis in old age 3. Acute appendicitis in pregnancy
54
Pathogenesis of Acute appendicitis in children in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
* Rapid perforation | * Misdiagnosed as gastroenteritis.
55
Pathogenesis of Rapid perforation in Acute appendicitis in children in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
Less developed omentum
56
Pathogenesis of Acute appendicitis in old age in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
* Gangrene & perforation are more frequent * Delay in diagnosis because of subtle symptoms * Mimics subacute I.O leading to enema & perforation. Cancer caecum should be suspected Due to obstruction not infiltration
57
Pathogenesis of Gangrene & perforation in Pathogenesis of Acute appendicitis in old age in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
Gangrene & perforation are more frequent due to | atherosclerosis & weakness of the immune system
58
Pathogenesis of Acute appendicitis in pregnancy in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
Pain & tenderness are higher up. Liable to perforation without localization Misdiagnosed as pyelonephritis.
59
Pathogenesis of increased liability to perforation without localization in Pathogenesis of Acute appendicitis in pregnancy in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
as the omentum is elevated.
