**Core Concept**
The question tests the understanding of potential complications arising from the rupture of a pancreatic cyst, specifically the risk of intestinal hemorrhage in the context of chronic pancreatitis.

**Why the Correct Answer is Right**
In a patient with chronic pancreatitis and a large pancreatic cyst, rupture of the cyst can lead to leakage of pancreatic enzymes and potential bleeding into the gastrointestinal tract. This is particularly concerning in the setting of chronic pancreatitis, where there is already inflammation and scarring of the pancreatic tissue. The location of the cyst adjacent to the pancreas increases the risk of intestinal involvement, including potential hemorrhage. The correct answer highlights the importance of considering the anatomical relationship between the pancreas and surrounding structures.

**Why Each Wrong Option is Incorrect**
**Option A:** Anaphylactic shock is a severe allergic reaction that is not directly related to the rupture of a pancreatic cyst. While anaphylaxis can occur in response to various triggers, it is not a typical complication of pancreatic cyst rupture.

**Option B:** Carcinomatosis refers to the spread of cancer cells throughout the body. While pancreatic cancer is a concern in patients with chronic pancreatitis, it is not a direct complication of cyst rupture. The question is focused on the immediate consequences of cyst rupture, rather than a long-term risk of cancer.

**Option C:** Disseminated infection is a potential complication of pancreatic necrosis or abscess formation, but it is not the most likely consequence of cyst rupture in this scenario. The patient's history of chronic pancreatitis and the presence of a cyst suggest a more localized risk, rather than a widespread infection.

**Option D:** Intestinal hemorrhage is the correct answer, as explained above.

**Clinical Pearl / High-Yield Fact**
Chronic pancreatitis can lead to the formation of pancreatic cysts, which can rupture and cause bleeding into the gastrointestinal tract. The risk of intestinal hemorrhage is increased in patients with a history of chronic pancreatitis and a pancreatic cyst, highlighting the importance of prompt evaluation and management of these patients.

**✓ Correct Answer:** D. Intestinal hemorrhage
