Chromoendoscopy Plus Mucosal Resection Versus Conventional Electrocoagulation for Intestinal Polyps in Children: Two Case Series

Meta-analysis of postoperative incision infection risk factors in colorectal cancer surgery

Objective

To evaluate the risk factors for postoperative incision infection in colorectal cancer, this meta-analysis aimed to identify key variables impacting infection incidence following colorectal cancer surgery.

Methods

Utilizing a meta-analytical approach, studies published from January 2015 to December 2022 were systematically collected and analyzed through the assessment of factors like body mass index, diabetes, albumin levels, malnutrition, and surgical duration.

Results

The meta-analysis of eleven high-quality studies revealed that elevated BMI, diabetes, low albumin levels, malnutrition, and extended surgical duration were associated with increased infection risk, while laparoscopic procedures showed potential for risk reduction.

Conclusions

This study underscores the significance of preoperative risk assessment and management in mitigating postoperative incision infections in colorectal cancer patients. The findings present actionable insights for clinicians to enhance patient prognoses and overall quality of life.

Polyps and Polyposis Syndromes in Children: Novel Endoscopic Considerations

Polypectomy is the most common therapeutic endoscopic intervention in children. Management of sporadic juvenile polyps is limited to polypectomy to resolve symptoms, whereas polyposis syndromes pose a multidisciplinary challenge with broader ramifications. In preparation for polypectomy, there are key patient, polyp, endoscopy unit, and provider characteristics that factor into the likelihood of success. Younger age and multiple medical comorbidities increase the risk of adverse outcomes, classified as intraoperative, immediate postoperative, and delayed postoperative complications. Novel techniques, including cold snare polypectomy, can significantly decrease adverse events but a more structured training process for polypectomy in pediatric gastroenterology is needed.

Endoscopic Mucosal Resection in Children

OBJECTIVES

Endoscopic mucosal resection (EMR) for removal of large polyps is well established in adults. EMR technique in the pediatric population is less utilized due to lower incidence of large intestinal polyps in pediatric patients and limited EMR training for pediatric gastroenterologists. The aim of this study is to retrospectively review safety and efficacy of pediatric EMR cases at two large, tertiary referral centers with adult and pediatric EMR expertise.

METHODS

A retrospective chart review was conducted at Cedars-Sinai Medical Center and Cincinnati Children's Hospital Medical Center from January 2012 to May 2021. Demographic, clinical, technical and follow up data were collected for patients <18 years of age who underwent EMR during the study period.

RESULTS

Fifteen pediatric EMR procedures were identified in 11 patients (five male, six female) during the study period. Indication was most frequently rectal bleeding. Polyp size removed ranged from 9 to 60 mm and pathology was consistent with juvenile inflammatory polyps in six patients. Technical success was achieved in 14 of 15 (93%) of EMRs with clinical success (desired clinical outcome) in all 13 procedures with clinical follow-up. There were no adverse events.

CONCLUSIONS

This study identifies a case series of pediatric patients who underwent EMR at two tertiary care centers. This series demonstrates successful EMR in children and shows a high technical and clinical success rate with a low complication rate. More investigation into EMR in pediatric patients is necessary, and its use should be isolated to centers with endoscopists with specific experience in EMR techniques.

Therapeutic Upper Gastrointestinal Endoscopy in Pediatric Gastroenterology

This paper seeks to give a broad overview of pediatric upper gastrointestinal (GI) pathologies that we are now able to treat endoscopically, acquired or congenital, and we hope this delivers the reader an impression of what is increasingly available to pediatric endoscopists and their patients.
