Instructions: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Input: Abstract: Three patients with postcholecystectomy unilateral hepatic duct stricture and subsequent liver atrophy were treated conservatively, with a successful outcome of up to three years follow up. A better understanding of the pathophysiological sequelae of segmental hepatic duct obstruction suggests that in such circumstances reconstructive surgery, with its attendant risks, may not invariably be necessary.
Which is the apt title for the abstract? option1: Expectant management of patients with unilateral hepatic duct stricture and liver atrophy. option2: Breast-feeding [letter]
Output:
Expectant management of patients with unilateral hepatic duct stricture and liver atrophy.
