INTRODUCTION: Gordonia species are rare aerobic Gram-positive actinomycetes and opportunistic pathogens. Their clinical manifestations and optimal management remain poorly defined. Gordonia sputi is an especially uncommon cause of soft-tissue and chest wall infections, and diagnosis is often delayed because of slow growth and difficulties in identification.

INTRODUCTION: Pancreaticoduodenectomy (PD) can be technically challenging in patients who previously underwent biliary reconstruction, particularly hepaticojejunostomy. The optimal strategy for managing a prior hepaticojejunostomy during PD has not been well established.

INTRODUCTION: Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare, low-grade malignant tumor. Although SPNs generally exhibit indolent behavior, spontaneous regression detected on CT imaging is exceedingly rare, and to the best of our knowledge, regrowth following regression has not been previously reported.

NTRODUCTION: Colorectal cancer outcomes depend not only on disease stage but also on surgical quality, particularly in locally advanced rectal cancer. Robot-assisted surgery offers advantages over laparoscopy but lacks haptic feedback. The da Vinci 5 Surgical System introduces Force Feedback (FFB) technology, which transmits kinesthetic sensations to the surgeon and quantifies forces, as well as Case Insights, an artificial intelligence–based intraoperative data platform. To the best of our knowledge, this report describes the first case of robot-assisted low anterior resection for rectal cancer performed in Japan using da Vinci 5.

INTRODUCTION: Crohn’s disease (CD) can be complicated by complex fistulas and abscesses, and laparoscopic surgery for such cases is difficult. We report a patient with CD who developed a complex fistula and retroperitoneal abscess that were treated using single-incision laparoscopic surgery.

INTRODUCTION: Gastric antral vascular ectasia (GAVE) is a condition characterized by clusters of dilated capillaries in the gastric antrum, leading to gastrointestinal bleeding. Although massive hemorrhage is rare, some cases present with recurrent minor bleeding, which can make endoscopic hemostasis challenging. Here, we report a case of GAVE that was refractory to argon plasma coagulation (APC) and required surgical intervention.
