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).

[EX Q]: Abstract: Methods for endoscopic retrograde cholangiography (ERC) and endoscopic papillotomy (EPT) in patients with Billroth-II operations are described, and experience with their use during the last four years (since 1980) is presented. Endoscopic retrograde cholangiopancreatography was successful in 134 of 147 patients (92%) and endoscopic papillotomy was successful in 46 of 50 patients. The described methods were used in two different hospitals by two different endoscopists and there was no difference in the results. We conclude that patients with a Billroth-II operation may undergo endoscopic diagnostic as well as therapeutic procedures with a high rate of success, with similar results as in ordinary patients and with no greater risk of complications.
Which is the apt title for the abstract? option1: Endoscopic retrograde cholangiography and endoscopic papillotomy in patients with a previous Billroth-II resection. option2: Leads from the MMWR. Congenital syphilis--United States, 1983-1985.
[EX A]: Endoscopic retrograde cholangiography and endoscopic papillotomy in patients with a previous Billroth-II resection.

[EX Q]: Abstract: The purpose of this article is to provide information that facilitates the critical evaluation of the thoracic outlet syndrome and other nerve entrapment syndromes in the regions of the posterior cervical triangle and the shoulder. General comments regarding entrapment are followed by discussions of specific entrapment sites. Each discussion stresses the anatomic view and includes comments on causes, symptoms, diagnostic tests, and management.
Which is the apt title for the abstract? option1: Neurovascular entrapment in the regions of the shoulder and posterior triangle of the neck. option2: Elevated plasma vasopressin (AVP) levels during resection of pheochromocytomas.
[EX A]: Neurovascular entrapment in the regions of the shoulder and posterior triangle of the neck.

[EX Q]: Abstract: The choice of which intraoperative monitors to use for routine cases is difficult, because a multitude of monitors is available today. Monitoring is deemed necessary to avoid problems, although there is little hard evidence that a specific monitor will improve outcome. The risk associated with modern noninvasive monitors, however, is negligible, and they should be considered for routine use in all patients. Although errors in the variables displayed or misuse of correct information can cause difficulties, these result from a lack of education and are not a valid reason to abandon a particular monitoring modality. Regular use of such monitoring tools as the electroencephalogram would allow clinicians to become familiar with how to interpret it in normal and crisis situations. The cost of a disaster during anesthesia (such as unrecognized hypoxia) is high. The dollars spent to cover a single major malpractice award could buy a tremendous number of monitors. The state of the art in the mid-1980s demands traditional anesthesia monitors plus continuous capnography and measurement of peripheral oxygenation. Other negligible-risk monitors should also be used when feasible. Improvement in monitoring design, particularly in output formats and in integration of monitored data, will be essential in the next few years, as will training in the proper use of monitors.
