Abstract:
Visceral pain is caused by either distension or contraction of the visceral muscular wall or obstruction of hollow gastrointestinal organs. Unlike the somatic pain due to peritonitis, visceral pain is diffuse, epigastric, periumbilical and is often accompanied by nausea, vomiting and restlessness. We demonstrate the significance of visceral pain in the differential diagnosis of the acute abdomen presenting five cases of appendicitis and cholecystitis. A correct early diagnosis of the acute abdomen while signs of local peritonitis are still absent (appendicitis in atypical location, recurrent acute appendicitis, spontaneous reopening of an occlusion) is facilitated by the awareness for the characteristics and symptoms of visceral pain, and therefore careful taking of the patient's history. A history lacking visceral pain on the other hand represents an important clue for the diagnosis of other conditions (gynecological, diverticulititis, etc.) with acute pelvic peritonitis.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Appendicitis-I: Introduction
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Abdominal Regions and Quadrants
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four quadrants...
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
