Bishop Robert Muench, head of the Catholic Diocese of Baton Rouge, will undergo two separate surgeries in the coming weeks, he said at Sunday Mass at St. Joseph Cathedral downtown.

The first surgery is scheduled for Tuesday to reverse an irregular heartbeat.

The second operation, scheduled for June 17, will remove a parathyroid gland that has developed a nodule, considered benign, and it will be an outpatient procedure.

“After months of tests,” the bishop said in a news release, “I have been diagnosed with two medical conditions that require separate surgeries. While all surgeries are serious, these surgeries are not viewed as life-threatening.”

Recovery from each surgery will be from one to two weeks.

Archbishop Emeritus Alfred Hughes will preside at next Sunday’s 10 a.m. annual Cathedral Bishop’s Day Mass and attend the reception that will follow at Boudreaux’s on Government Street.

Hughes was Muench’s predecessor as Bishop of Baton Rouge and he is the retired Archbishop of New Orleans.

Muench said that his not being able to participate in scheduled events “causes me more personal concern than the surgeries themselves. I sincerely apologize and trust everyone will understand.”

The Rev. Than Vu, the Vicar General of the diocese, will assume the additional responsibility of diocesan management during the bishop’s recuperation.

“The doctors have asked that the bishop receive no visitors during his recovery period so that he can get needed rest and the recovery be as quick as possible,” Vu said in the release.
