Supplementary Material to ‘Subtotal cholecystectomy: results of a single-centre, registry-based retrospective cohort study of 180 adults in 2011–2018’

A cholecystectomy is a standard treatment for symptomatic cholecystolithiasis. Significantly less focus, however, is given to subtotal cholecystectomy (STC), the alternative procedure to conventional cholecystectomy in extraordinary surgical situations. We produced a multi-aspectual report that aims to reduce the STC-specific knowledge gap and inform clinical decision-making strategies. The Supplementary Material is organised into broad sections that follow the structure of the main paper. It provides further introductory and methodological detail. It contains data within the 109 tables and 53 figures that are complementary and directly relevant to the article content. It offers the comprehensive descriptions of results for the cohort of 180 patients and its six subgroups stratified by surgical setting (elective/non-elective), surgical approach (open/laparoscopic), and type of completion of the procedure (reconstituting/fenestrating). The core of the main paper is formed around these tables and figures. We used three methods to improve the search, visibility, and readability of the information provided in the main text of the Supplementary Material and each page containing the STC figure or STC table. First, each reference to the STC figure or STC table within the main text of the Supplementary Material is in blue letters. Second, each page with STC figure or STC table contains a reference to a section of the main text of the Supplementary Material, in which the comments on an individual figure or table are provided. Third, key points related to individual STC table or STC figure are provided below each table or figure. The style of terms of the supplemental content conforms to the rest of the paper.胆囊切除术（cholecystectomy）是症状性胆囊结石症（symptomatic cholecystolithiasis）的标准治疗方案。然而，次全胆囊切除术（subtotal cholecystectomy, STC）作为非常规手术场景下替代常规胆囊切除术的可选术式，却未受到足够关注。本研究撰写了一份多维度研究报告，旨在填补STC相关的专业知识空白，为临床决策制定提供参考依据。 本研究的补充材料依照主论文的结构框架划分为多个大类板块，提供了更详尽的引言与方法学细节。该补充材料包含109张表格与53幅图表，其中的数据与正文内容高度互补且直接相关。此外，补充材料还全面呈现了180例患者队列及其6个亚组的研究结果：亚组按手术场景（择期/非择期）、手术入路（开腹/腹腔镜）以及术式完成类型（重建式/开窗式）进行分层。主论文的核心内容正是围绕上述图表与表格展开。 为提升补充材料正文及所有包含STC图表的页面的信息检索效率、可及性与可读性，本研究采用了三项优化策略：其一，补充材料正文中所有提及STC图表的内容均采用蓝色字体标注；其二，每张包含STC图表的页面均标注了补充材料正文中对应的章节指引，该章节包含对单张图表或表格的详细评述；其三，每张表格或图表下方均附上了与其相关的核心要点说明。 补充材料的术语表述风格与论文其余部分保持一致。
