Final answer:
Splenorrhaphy is the recent repair option for a splenic laceration if the spleen is salvageable, otherwise, a splenectomy may be necessary for severe cases. Shoulder pain, or Kehr's sign, is a recognized symptom of splenic damage.
Step-by-step explanation:
The recent repair for a splenic laceration associated with epigastric pain and shoulder pain is known as splenorrhaphy (option 2). This procedure involves the surgical repair of the spleen. The manifestation of shoulder pain, known as Kehr's sign, is due to the referral of pain via the phrenic nerve from diaphragmatic irritation caused by blood or other substances in the abdominal cavity, a phenomenon seen with spleen damage. However, the treatment option would ultimately depend on the severity of the laceration, with splenectomy (option 1) being necessary for severe cases where the spleen cannot be salvaged.
Shoulder pain related to splenic injury is often experienced in the left shoulder and is sometimes mistaken for symptomatic issues related to cardiovascular or pulmonary systems, but the true cause is the sympathetic fibers connected to the spleen from the celiac ganglion when there is a tear or rupture in spleen tissue. The other terms mentioned, such as superior mesenteric, gastro-omental, pancreaticoduodenal, and so on, are names of vessels and are not directly related to the repair of the said injury but are part of the overall abdominal vascular anatomy.
