PREPRINT RELEASE: Distal Gastrectomy (Open)

Distal Gastrectomy (Open)
John T. Mullen, MD
Director, General Surgery Resident Program
Massachusetts General Hospital


An 80-year-old patient with anemia undergoes an upper endoscopy that reveals inflammation in the distal stomach. Biopsies identify it as an early intramucosal adenocarcinoma while an endoscopic ultrasound shows the tumor invading the muscle of the stomach. Given that there are no signs of metastasis, the patient presents for a potentially curative gastrectomy where Dr. John Mullen removes the distal two-thirds of the stomach, performs a D1 lymph node dissection and a partial D2 lymph node dissection, and reconstructs in a Billroth II fashion.

Abstract: Total knee arthroplasty has evolved into a very successful procedure to relieve pain and restore function in the arthritic knee with advanced structural damage. Optimal results are dependent on the restoration of alignment and ligament stability. Operative techniques involve either preservation of the posterior cruciate ligament or substitution of its function through increased prosthetic constraint. The vast majority of knees do not require cruciate substitution to establish appropriate stability and function. This video outlines the operative technique used by the author for posterior cruciate-retaining total knee arthroplasty in a patient with a preoperative varus deformity.

In a staple surgery for conductive hearing loss, Dr. Calhoun Cunningham III performs a laser stapedotomy and prosthesis placement via transcanal approach. A thickened footplate does not preclude its success in alleviating the patient's longstanding hearing loss.
