Background: Surgeons variously estimate usage of mechanical staplers in digestive surgery especially about the increase of the incidence of late complications like stricture (as some authors refer). We report a histomorphological aid to the comparison of staplers and hand-sewn sutures. Our aim was to observe at long term the healing process in the sutured tissue in the canine gastro-enteric tract.
Methods: We describe three histological pieces: one manual suture in a dog which was euthanatized and necropsied 5 months after operation and two mechanical sutures performed in two different dogs: one died because of a gastric torsion 18 months after the operation while the other was euthanatized 5 months after the operation. The histomorphological study has been carried out with a peculiar cutting (Exact) and including method which lets the staples in situ.
Results And Conclusions: Compared analysis showed that cicatrization goes on better in stapled than in hand sutured tissue.

Objective: CSF leaks are a significant source of patient morbidity following intradural spine surgeries. Watertight dural closure is crucial during these procedures to minimize the risk of a CSF leak. This study reports postoperative outcomes and changes in patient management after switching to penetrating titanium clips for dural closure in a large cohort of pediatric patients receiving a tethered cord release (TCR) or a selective dorsal rhizotomy (SDR).

Background: Metastatic spine tumor surgery (MSTS) is often complex and extensive leading to significant blood loss. Allogeneic blood transfusion (ABT) is the mainstay of blood replenishment but with immune-mediated postoperative complications. Alternative blood management techniques (salvaged blood transfusion [SBT]) allow us to overcome such complications.

Objective: Skull base chordomas (SBCs) often present with cranial nerve (CN) VI deficits. Studies have not assessed the prognosis and predictive factors for CN VI recovery among patients presenting with CN VI deficits.
Methods: The medical records of patients who underwent resection for primary chordoma from 2001 to 2020 were reviewed.

Purpose: Human epidermal growth factor receptor 2 (HER2)-targeted therapies have shown promise in treating -amplified metastatic colorectal cancer (mCRC). Identifying optimal biomarkers for treatment decisions remains challenging. This study explores the potential of artificial intelligence (AI) in predicting treatment responses to trastuzumab plus pertuzumab (TP) in patients with -amplified mCRC from the phase II TRIUMPH trial.

Purpose: The available scientific evidence on the effectiveness of the surgical treatment of peri-implantitis is limited. The aim of this study was to assess the risk of recurrence or disease progression in patients with peri-implantitis that underwent surgical treatment.
Materials And Methods: A retrospective cohort study was carried out in patients subjected to peri-implant surgery between 2015 and 2021, and with a minimum follow-up of 12 months.
