Article Abstract
Background: Anastomotic leak after esophagectomy carries important short- and long-term sequelae. The authors conducted a systematic review and meta-analysis to determine its association with surgical volume.
Materials And Methods: A systematic literature review was performed to identify all studies reporting on anastomotic leak after esophagectomy. Studies with less than 100 cases were excluded. The primary outcome was postesophagectomy anastomotic leak, while secondary outcomes were operative mortality overall and after anastomotic leak. Pooled event rates (PER) were calculated, and the association with annual esophagectomy volume by center was investigated.
Results: Of the 3932 retrieved articles, 472 were included ( n =177 566 patients). The PER of anastomotic leak was 8.91% [95% CI=8.32; 9.53%]. The PER of early mortality overall and after an anastomotic leak was 2.49% [95% CI=2.27; 2.74] and 11.39% [95% CI=9.66; 13.39], respectively. Centers with less than 37 annual esophagectomies had a higher leak rate compared to those with greater than or equal to 37 annual esophagectomies (9.58% vs. 8.34%; P =0.040). On meta-regression, surgical volume was inversely associated with the PER of esophageal leak and of early mortality.
Conclusions: The frequency of anastomotic leaks after esophagectomy, perioperative, and leak associated mortality are inversely associated with esophagectomy volume.

Aortic hemorrhage following anastomotic leakage after esophagogastric surgery before and after implementation of endoscopic vacuum therapy.
Surg Endosc

Department of Surgery, Amsterdam UMC Location University of Amsterdam, Meibergdreef 9, Amsterdam, The Netherlands.
Background: Endoscopic vacuum therapy (EVT) has been established as a safe and effective treatment for anastomotic leakage. While rare, major aortic hemorrhage has been reported as a severe complication potentially associated with EVT. However, significant hemorrhages have also been observed in patients with transmural defects in the upper gastrointestinal tract, without the use of EVT.

Department of Surgery, Boston Medical Center, Chobanian and Avedisian School of Medicine, Boston University, Boston, MA.
Background: Rural populations experience higher colon cancer (CC) mortality than urban populations, and rural patients may have more complications following resection. Reoperations due to complications following CC resection among rural and urban patients are not clear, and factors mediating disparities in rural-urban postoperative outcomes have not been examined.
Study Design: Using the SEER-Medicare database, individuals with CC who underwent surgical resection were compared via multivariable logistic regression to determine the association of rurality with postoperative complications and reoperations at 30, 60, and 90 days.

Internal Medicine Department, Mirwais Regional Hospital, Kandahar, Afghanistan.
Background: The primary treatment for colorectal cancer, which is very prevalent, is surgery. Anastomotic leaking poses a significant risk following surgery. Intestinal perfusion can be objectively and instantly assessed with indocyanine green fluorescence imaging, which may lower leakage rates and enhance surgical results.

Purpose: This meta-analysis compares thoracoscopic versus open thoracotomy repair of esophageal atresia with tracheoesophageal fistula (EA/TEF).
Methods: We systematically searched PubMed, Web of Science, Cochrane Library, and Scopus from inception to April 2025 for studies comparing thoracoscopic versus conventional thoracotomy approaches. Two independent reviewers screened studies, extracted data, and assessed risk of bias using appropriate tools.
The role of remote ischaemic preconditioning (RIPC) in colorectal surgery: a meta-analysis of randomized-controlled studies.

Department of Surgery (A), Medical Faculty, Heinrich-Heine-University, University Hospital Duesseldorf, Duesseldorf, Germany.
Introduction: Remote ischaemic preconditioning (RIPC) which consists of repeated brief episodes of non-lethal limb ischaemia is associated with organ protection and improved clinical outcomes through complex pathophysiological pathways. The aim of this meta-analysis was to evaluate the postoperative effects of RIPC in bowel recovery and surgical morbidity after colorectal surgery.
Methods: In strict adherence to the PRISMA guidelines, a systematic literature search was performed for studies comparing the postoperative effect RIPC in colorectal surgery.
