Objectives: To identify reporting guidelines related to surgical technique and propose recommendations for areas that require improvement., Study Design and Setting: A protocol-guided scoping review was conducted. A literature search of MEDLINE, the EQUATOR Network Library, Google Scholar, and Networked Digital Library of Theses and Dissertations was conducted to identify surgical technique reporting guidelines published up to December 31, 2021., Results: We finally included 55 surgical technique reporting guidelines, vascular surgery (n = 18, 32.7%) was the most common among the clinical specialties covered. The included guidelines generally showed a low degree of international and multidisciplinary cooperation. Few guidelines provided a detailed development process (n = 14, 25.5%), conducted a systematic literature review (n = 13, 23.6%), used the Delphi method (n = 4, 7.3%), or described post-publication strategy (n = 6, 10.9%). The vast majority guidelines focused on the reporting of intraoperative period (n = 50, 90.9%). However, of the guidelines requiring detailed descriptions of surgical technique methodology (n = 43, 78.2%), most failed to provide guidance on what constitutes an adequate description., Conclusion: Our study demonstrates significant deficiencies in the development methodology and practicality of reporting guidelines for surgical technique. A standardized reporting guideline that is developed rigorously and focuses on details of surgical technique may serve as a necessary impetus for change., (Copyright © 2022 The Authors.

Background: Most nomograms for Gastric Cancer (GC) were developed to predict overall survival (OS) after curative resection. The Italian Research Group for Gastric Cancer (GIRCG) prognostic scoring system (PSS) was designed to predict the recurrence risk after curative treatment based on pathologic tumor stage and treatment performed (D1-D2/D3 lymphadenectomy). This study was carried out to externally validate the GIRCG's PSS., Patients and Methods: Adopting the same criteria used by GIRCG to build the PSS, 185 patients with GC operated with curative intention were selected. The median follow-up period was 77.8 months (1.93-150.8) for all patients and 102.5 months (60.9-150.8) for patients free of disease. The NRI (net reclassification improvement) was calculated to estimate the overall improvement in the reclassification of patients using the PSS in place of the TNM stage system., Results: GC recurrence occurred in 70 (37.8%) patients. The mean time to recurrence was 22.2 (range 1.9-98.1) months. For patients with recurrence, the gain in the proportion of reclassification was 0.257 (p < 0.001), indicating an improvement of 26%. For patients without recurrence, the gain in the proportion of reclassification was -0.122 (p < 0.001), indicating a worsening of 12%. The NRI calculated was 0.135 (p = 0.0527)., Conclusion: The GIRCG's PSS, which predicts the likelihood of recurrence after radical surgical treatment for GC, is more accurate than TNM system to predict recurrence mainly for high-risk patients. Yet, the PSS does not have the same effectiveness for low-risk patients, overestimating the chance of recurrence occurs even for disease-free patients., (Copyright © 2015 Elsevier Ltd.
