Preprints with The Lancet is a collaboration between The Lancet Group of journals and SSRN to facilitate the open sharing of preprints for early engagement, community comment, and collaboration. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early-stage research papers that have not been peer-reviewed. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. The findings should not be used for clinical or public health decision-making or presented without highlighting these facts. For more information, please see the FAQs.

Background: The purpose of this study was to find out the perioperative clinical factors and demographic characteristics associated with shoulder pain after laparoscopy(PLSP).
Methods: A prospective observational study was performed with 442 inpatients undergoing laparoscopic surgery for infertility.The pain visual analogue scale was used as the measuring instrument. To identify the predictors of PLSP, we performed multivariate conditional logistic regression.
Findings: PLSP was well correlated with body mass index(odds ratio (OR)=0.848). The incidence of shoulder pain and more severe shoulder pain in patients with lower BMI is significantly higher than that in patients with higher BMI, and BMI is significantly negatively correlated with PLSP. Most of the patients (97%) began to have shoulder pain after the first out of bed activity, rarely during bed rest.
Interpretation: The variation of PLSP data may be partly due to BMI and postoperative patient's position change.We should carry out more rigorous experimental design to exclude the impact of BMI and postoperative activities on PLSP data.
Trial Registration: The study was registered with the Chinese Clinical Trial Registry (ChiCTR-OOC-16008044).
Funding Statement: There were no funders for the study.
Declaration of Interests: The authors have no competing interests to declare.
Ethics Approval Statement: The study was approved by the institution’s IRB (2016–11).
