RESUMO
PURPOSE: This study aims to define the extent of additional surgical procedures after abdominal wall closure (AWC) in patients with gastroschisis (GS) and omphalocele (OC) with special focus on gastrointestinal related operations. METHODS: A retrospective chart review was performed including all operations in GS and OC patients in the first year after AWC (2010-2019). The risk for surgery was calculated using the one-year cumulative incidence (CI). RESULTS: 33 GS patients (18 simple GS, 15 complex) and 24 OC patients (12 without (= OCL), 12 OC patients with liver protrusion (= OCL +)) were eligible for analysis. 43 secondary operations (23 in GS, 20 in OC patients) occurred after a median time of 84 days (16-824) in GS and 114.5 days (12-4368) in OC. Patients with complex versus simple GS had a significantly higher risk of undergoing a secondary operation (one-year CI 64.3% vs. 24.4%; p = 0.05). 86.5% of surgical procedures in complex GS and 36.3% in OCL + were related to gastrointestinal complications. Complex GS had a significantly higher risk for GI-related surgery than simple GS. Bowel obstruction was a risk factor for surgery in complex GS (one-year CI 35.7%). CONCLUSION: Complex GS and OCL + patients had the highest risk of undergoing secondary operations, especially those with gastrointestinal complications.

Fluorescence confocal microscopy (FCM) is an optical technique that uses laser light sources of different wavelengths to generate real-time images of fresh, unfixed tissue specimens. FCM allows histological evaluation of fresh tissue samples without the associated cryo artifacts after frozen sectioning. The aim of this study was to prospectively evaluate pediatric tumor specimens and assess their suitability for fresh tumor sampling. In addition, we aimed to determine whether tumor cell isolation for stable cell culture is still feasible after FCM imaging. Pediatric tumor specimens were imaged using FCM. Tumor viability and suitability for tissue sampling were evaluated and compared with H&E staining after paraffin embedding. In addition, FCM-processed and non-FCM-processed tissue samples were sent for tumor cell isolation to evaluate possible effects after FCM processing. When comparing estimated tumor cell viability using FCM and H&E, we found good to excellent correlating estimates (intraclass correlation coefficient = 0.891, p < 0.001), as well as substantial agreement in whether the tissue appeared adequate for fresh tissue collection (κ = 0.762, p < 0.001). After FCM, seven out of eight samples yielded passable cell cultures, compared to eight out of eight for non-FCM processed samples. Our study suggests that the use of FCM in tumor sampling can increase the yield of suitable fresh tumor samples by identifying viable tumor areas and ensuring that sufficient tissue remains for diagnosis. Our study also provides first evidence that the isolation and growth of tumor cells in culture are not compromised by the FCM technique.

BACKGROUND/AIMS: The approach to small bowel obstruction, when unrelieved with medical management, is open or laparoscopic exploration, often necessitating lysis of adhesions and the resection of any compromised bowel. In patients with prior bowel resections, the surgeon must tread a fine line, so as not to precipitate the clinical derangement known as short bowel syndrome (SBS). Techniques have been described that curtail the extent of intestinal resection, but these are primarily limited to the pediatric literature and are not commonly practiced in the general surgical population. METHODS: We report a case of a complicated small bowel obstruction in a patient with pre-existing short bowel length, in which a tapering enteroplasty was performed. RESULTS: Antimesenteric tapering successfully achieved a return of bowel function, avoiding the morbidity of an extended small bowel resection and the possibility of developing SBS. CONCLUSION: In such patients who are at high risk of developing SBS, in whom a segment of dilated small bowel has become defunctionalized, leading to significant and life-threatening symptoms, this procedure has the potential to help prevent SBS and its lifelong complications and associated mortality.
