AI Article Synopsis
- The study investigates the relationship between preoperative performance on the 6-minute walk test (6MWT) and postoperative complications in patients undergoing laparoscopic gastrointestinal cancer surgery.
- It found that patients who walked further in the 6MWT before surgery experienced fewer complications after surgery, with an average difference of 33.5 meters between those with and without complications.
- These results suggest that better preoperative cardiopulmonary function, as measured by the 6MWT, is linked to a lower likelihood of facing postoperative complications.
Article Abstract
Objective: The 6-min walk test (6MWT) is a simple and valid method to evaluate cardiopulmonary function. We performed this prospective study in patients undergoing laparoscopic gastrointestinal cancer surgery to explore the association between preoperative 6MWT performance and overall postoperative complications.
Methods: This study was registered at clinicaltrials.gov (NCT03711526). The study consecutively enrolled patients receiving laparoscopic gastrointestinal cancer surgery in our institution. All patients performed the 6MWT upon recruitment and received 30 days of postoperative follow-up. The primary outcome was overall complications, defined by ≥ grade I Clavien-Dindo (CD) classification (2004) complications. Multivariable logistic regression was used to test the association of 6-min walk distance (6MWD) with the outcome.
Results: A total of 184 patients were included in the final analyses. In the 37 (20.1 %) patients with overall complications, the mean (standard deviation) preoperative 6MWD was 469.1 (86.8) m. In patients with no complications, the 6MWD was 502.6 (90.2) m. The mean difference was 33.5 m (95 % confidence interval, 1.3, 65.7; P = 0.042). A longer preoperative 6MWD was associated with a lower odds of developing postoperative complications (odds ratio, 0.994 per meter increase; 95 % confidence interval, 0.989, 0.999; p = 0.023).
Conclusion: This study indicated an association between the preoperative 6MWD and postoperative complications in patients undergoing laparoscopic gastrointestinal cancer surgery.

Background: Previous studies have reported the effectiveness of the "enhanced recovery after surgery" program in patients who underwent gastric cancer surgery, mostly based on the 2014 gastrectomy guidelines. Therefore, based on subsequent advancements in perioperative management, this randomized, controlled, open-label, single-center study aimed to assess the impact of a recent evidence-based multimodal enhanced recovery after surgery program on the quality of early recovery after gastric cancer surgery.
Materials And Methods: This study included adult patients scheduled to undergo elective laparoscopic or robotic distal gastrectomy for gastric cancer.
Background: Occult inguinal hernia is a unique clinical challenge characterized by asymptomatic presentation and the absence of detectable signs on physical examination, leading to frequent misdiagnosis and underdiagnosis. The advancement of laparoscopic hernia surgery has facilitated the identification of occult hernias, yet effective diagnostic and predictive methods remain lacking.
Objective: This study aims to evaluate the incidence and clinical characteristics of occult inguinal hernias detected during laparoscopic unilateral inguinal hernia repair and to provide evidence-based recommendations for their management.
Introduction: Post-sleeve gastrectomy (SG) proximal staple line leak is a rare yet serious complication. Endoscopic negative pressure therapy (ENPT) has emerged as a safe technique, showing promising results in treating leakages of the upper and lower gastrointestinal tract, often in conjunction with surgical interventions. A standardized treatment algorithm has not been established.

Background: Gastric cancer patients without invasion of the squamocolumnar junction have a low probability of extragastric mesenteric metastasis, and the survival benefit of conducting D2 lymphadenectomy plus complete mesogastrium excision is unclear in this group of patients.
Methods: This was a retrospective analysis of patients with stage II/III gastric cancer without invasion of the squamocolumnar junction who underwent laparoscopic radical surgery for gastric cancer at the First Hospital of Putian City, Fujian Province, from January 2014 to May 2019. Five-year disease-free survival was the primary outcome, and 5-year overall survival and the recurrence pattern were the secondary outcomes.
