Background: Although emergency surgery may reduce mortality in patients with severe spontaneous intracerebral hemorrhage (SSICH), the effectiveness and safety of surgical treatment among SSICH patients receiving long-term oral antiplatelet therapy (LOAPT) remain unclear. The CRISIH registry was originally designed to evaluate the effect and safety of emergency surgery in SSICH patients receiving LOAPT and has subsequently continued as an ongoing multicenter registry of spontaneous intracerebral hemorrhage. Methods: The CRISIH registry is an ongoing prospective, multicenter cohort registry conducted across participating clinical centers in China. The registry was initiated in November 2019 and is designed as a 10-year registry with continued recruitment and follow-up. Data from the initial five-year enrollment period are used for interim and secondary analyses, while recruitment and follow-up continue during the subsequent registry period. Clinical, radiological, surgical, laboratory, and follow-up information are collected using standardized case report forms. For the originally registered primary outcome, patients are followed until death or 6 months after the occurrence of primary hemorrhage; selected follow-up assessments and secondary analyses may extend beyond this period according to the registry protocol. Study Design: The CRISIH registry was designed as a prospective, multicenter cohort registry of patients with spontaneous intracerebral hemorrhage. One originally registered comparative focus evaluates SSICH patients receiving LOAPT, comparing total mortality and survival outcomes between patients receiving emergency surgical treatment and those receiving conservative treatment. The safety of surgery is assessed by comparing postoperative hemorrhagic complications among operated patients with and without LOAPT. Based on the observed clinical characteristics and outcomes of patients receiving LOAPT, the registry also evaluates ischemic events after discontinuation of LOAPT and explores coagulation function assessment strategies in operated patients receiving LOAPT. Objective: The CRISIH registry aims to prospectively evaluate clinical outcomes and management strategies in patients with spontaneous intracerebral hemorrhage. An originally registered focus of the registry is to assess the effectiveness and safety of emergency surgery among SSICH patients receiving LOAPT, thereby generating evidence to support future clinical management. Secondary Analysis Update: The present update describes an interim secondary analysis of the ongoing CRISIH registry based on patients enrolled during the initial five-year period from November 2019 to December 2024. This analysis focuses on postoperative disorders of consciousness after surgery for spontaneous intracerebral hemorrhage, with consciousness status assessed at 30, 90, 180, and 365 days after surgery using the Coma Recovery Scale-Revised. This interim secondary analysis does not alter the ongoing registry design, recruitment status, or originally registered primary outcome.

The aim of this study was to compare the effectiveness of chlorhexidine versus saline in flushing the surgical area during colorectal cancer surgery. The primary outcomes included surgical site infection, postoperative complication rates, et al.

To evaluate the effectiveness of the gastroscopy, air, and methylene blue (GAM) leak testing in reducing the incidence of postoperative anastomotic complications, especially anastomotic leakage, in patients with colorectal cancer. The primary outcomes included is the incidence of anastomotic complications (mainly anastomotic leak) within 30 days after surgery

Evaluate the safety and efficacy of postoperative Pre-emptive EVT (PEVT) in reducing the incidence of anastomotic leaks within 30 days after surgery in patients with colorectal cancer. Compare the differences between the PEVT group and the control group in terms of operation time, length of hospital stay, and total medical costs. Analyze the incidence of other postoperative complications in the two groups, such as wound infection, abdominal abscess, and intestinal obstruction. Assess the impact of PEVT on postoperative recovery indicators, including time to first flatus, time to first defecation, and time to ambulation. Observe the occurrence of PEVT-related adverse events, such as device displacement, bleeding, and infection.

This prospective study investigates the effects of neoadjuvant therapy on endothelial function, microvascular tissue density, and tissue fibrosis in patients with colorectal cancer and their association with perioperative complications. The primary objective is to assess differences in microvascular tissue density between patients who received neoadjuvant therapy and those who did not, biomarkers, and demographic factors between patients who received neoadjuvant therapy and those who underwent surgery as initial treatment, and to compare clinical outcomes. The study will include 34 patients treated with neoadjuvant therapy and 34 patients for whom surgery is the first-line treatment. Patients will be followed until discharge from the hospital, and complications after discharge will be monitored through medical records one month after surgery.

This study aims to compare the effects of using prophylactic abdominal drainage tubes during Enhanced Recovery After Surgery (ERAS) in patients undergoing Laparoscopic Distal Gastrectomy (LDG) for gastric cancer through a multicenter non-inferiority randomized trial. The study is divided into two groups: 1. ERAS-tubeless group: The ERAS protocol without nasogastric decompression, nasojejunal feeding or prophylactic abdominal drainage tubes. 2. ERAS-tube group: the ERAS protocol with prophylactic abdominal drainage tubes, along with no nasogastric decompression or nasojejunal feeding tubes. Patients will be randomly assigned to the two groups in a 1:1 ratio, with the primary analysis based on the modified intention-to-treat population (mITT) and secondary analysis on the per-protocol (PP) population. Perioperative management will adhere to ERAS guidelines, and postoperative quality of life will be assessed using the EORTC QLQ-C30 questionnaire and QoR-15 scores. Preliminary training on the standard ERAS protocol is administered to all members in the team before the initiation of the study, ensuring in-group members to fully master the requirements and other related contents in the study. Data collectors, analysts, and outcome evaluators will remain blinded to group allocation. The findings of this study are expected to provide high-quality evidence on the feasibility of omitting prophylactic abdominal drainage in the context of ERAS, thereby contributing to the optimization of postoperative management strategies for gastric cancer surgery.

For seniors aged 65 and over (inclusive) undergoing surgical procedures (bone surgery, traumatology, orthopedics) in an acute or elective setting, the relationship between preoperative urinary tract infection/colonization (within 30 days before the procedure) and the occurrence of predefined postoperative complications (monitoring during the patients' hospitalization) will be observed

This prospective cohort study enrolls subjects who experience carbon monoxide (CO) poisoning. The purpose of the study is to evaluate therapeutic effects of various treatments and short and long-term outcomes in CO poisoned patients. In addition, complications of brain and heart susceptible to CO are investigated through various ways and the association between complications and the patient's prognosis is also investigated. All subjects will be regularly monitored by physicians participating in this study.
