Former Gov. Ben Cayetano was released from the hospital today after doctors confirmed the mayoral candidate suffered a bleeding ulcer, his campaign said.

Cayetano underwent an endoscopy on Tuesday in which doctors examined the affected area of his stomach and cauterized a blood vessel to prevent further bleeding, the campaign said in a news release.

No further problems were found. 

“After monitoring the former Governor’s progress, doctors released him at 5 p.m. today and he is expected to fully recover,” the release said.

Cayetano was admitted to the Queen’s Medical Center on Sunday, after going to the emergency room with symptoms of a bleeding ulcer, his wife, Vicky, said Monday. Preliminary tests indicated a bleeding ulcer. He suffered a similar event in 1997, as governor, and was hospitalized for five days. 

“We are extremely thankful to everyone who has sent us their well-wishes for a speedy recovery for Ben,” Vicky Cayetano said in a statement. “We are pleased with the news of his release as he will feel much better resting in the comfort of his own home as he prepares for this Saturday’s primary election.”

Cayetano is the front-runner in the campaign for Honolulu mayor, running against incumbent Mayor Peter Carlisle and former city Managing Director Kirk Caldwell. The Hawaii Poll, conducted recently for the Star-Advertiser and Hawaii News Now, showed Cayetano with a lead over both rivals.

Cayetano continued working and kept up-to-date on campaign details with a laptop in his hospital room. 

According to an email message from Peter Kay, Cayetano’s online campaign manager, Cayetano was up past midnight working on a statement in support of an online campaign that asks political candidates to pledge support to open government.

“At 12:34 a.m. today, Gov. Cayetano, working on his laptop from his hospital bed has released this statement on his support of the honolulu.govfresh.com pledge,” Kay wrote in a message time-stamped at 1:24 a.m.
