AI Article Synopsis
- A 77-year-old man was treated for cecal cancer with lung and liver metastases using a combination of chemotherapy and surgery, showing initial success with tumor reduction and no new metastatic lesions.
- After several surgeries, including tumor resections in different locations and a decline in tumor markers, a new mass was discovered near a mesh-plug prosthesis, indicating potential metastasis.
- The case highlights the risk of malignant tumor metastases at surgical sites, particularly in patients with advanced cancer, emphasizing the need for careful monitoring of patients with similar histories for signs of recurrence around surgical implants.
Article Abstract
We report the case of a 77-year-old man who presented to our hospital with cecal cancer, lung metastasis, and liver metastasis in January 2013. After four courses of modified infusional intravenous fluorouracil and levofolinate with oxaliplatin (mFOLFOX 6) + bevacizumab, there was no new metastatic lesion and lung metastasis reduction was observed. Ileocecal resection was performed in May, left lower lung lobectomy in August, and extended right posterior segmentectomy + S8 partial liver resection was performed in December. The tumor marker declined initially;thereafter, it gradually increased. Computed tomography (CT) performed in April 2014 revealed right inguinal mass around the mesh-plug prosthesis. A positron emission tomography-CT (PET-CT) also revealed a high 2-fluoro-2-deoxy-D-glucose (FDG) uptake at the same site. Right inguinal tumor resection was performed in July. Cancer tissues were confirmed by performing intraoperative rapid pathological diagnosis, and R0 resection could be achieved. Previous studies have reported malignant tumor metastases to the mesh-plug prosthesis, and this was believed to one of the sites that cancer cells can easily engraft. In particular, in patients with a history of advanced malignant tumors, if mass formation around the artifact insertion site is observed, the possibility of peritoneal metastasis should be considered.

Thalamic stereo-electroencephalography exploration in pediatric drug-resistant epilepsy: implantation technique and complications.
J Neurosurg Pediatr

Objective: Patients with drug-resistant epilepsy (DRE) are often referred for phase II evaluation with stereo-electroencephalography (SEEG) to identify a seizure onset zone for guiding definitive treatment. For patients without a focal seizure onset zone, neuromodulation targeting the thalamic nuclei-specifically the centromedian nucleus, anterior nucleus of the thalamus, and pulvinar nucleus-may be considered. Currently, thalamic nuclei selection is based mainly on the location of seizure onset, without a detailed evaluation of their network involvement.

Background: Solid pseudopapillary neoplasms (SPNs) arising in the body or tail of the pancreas can be amenable to laparoscopic distal pancreatectomy with or without concomitant splenectomy. The purpose of this study was to evaluate laparoscopic distal pancreatectomy for SPN using the Warshaw technique as a means to preserve spleens in children.
Methods: We reviewed our database of SPN patients 19 years and younger (January 2006-December 2023).

Background: Textbook outcome (TO) has been utilized to assess the quality of surgical care. This study aimed to define TO rates for minimally invasive gastric gastrointestinal stromal tumor (GIST) resections in a bi-institutional cohort.
Methods: Patients with gastric GIST (≤ 5 cm) who underwent laparoscopic or robotic resection (January 2014 to January 2024) were retrospectively identified from two GIST centers.

Purpose: We sought to evaluate the incidence, natural history, and management of cystic spinal lesions following myelomeningocele/myeloschisis closure.
Methods: We performed a single-center retrospective review of all patients who underwent myelomeningocele/myeloschisis closure from 2013 to 2018 with follow-up to 5 years old.
Results: We analyzed 100 fetal repairs and 81 postnatal closures from 305 total surgeries.
