Left/Right across multi-line equation

I have a multi-line equation that I want to have matching sized parentheses. The advice I read online was to use \left( equation \right. \\ left. rest-of-equation \right) . However, this syntax leaves first half of the equation unaware of what is in the second half. For example, if you include a square root term after the break, the second parenthesis will be larger than the opening parenthesis. When you are using the aligned environment to split a long equation this can look somewhat offputting.

Compare the top equation to the bottom one. The parentheses match in size for the bottom equation, but the left hand parentheses for the top one is noticeably smaller.

Top Code:

\begin{aligned}[t]
\gamma_{\text{u}} + \frac{1}{108}
\left(57\gamma_{\text{er}} \right. &+  38\gamma_{\text{se}}\\ & {}\pm
\left.\sqrt{2601 \gamma_{\text{er}}^2 + 3648
\gamma_{\text{er}}\gamma_{\text{se}} + 1444 \gamma_{\text{se}}^2}
\right)
\end{aligned}

Bottom Code:

\begin{aligned}[t] \gamma_{\text{u}} + \frac{1}{16}
\left(9\gamma_{\text{er}}  +  6\gamma_{\text{se}} \pm  \sqrt{49
\gamma_{\text{er}}^2 + 76 \gamma_{\text{er}}\gamma_{\text{se}} + 36
\gamma_{\text{se}}^2} \right) \end{aligned}
