Gallbladder cancer (GBCA) is a relatively uncommon disease with dismal prognosis. As the symptoms associated with GBCA are vague and non-specific, most patients present when the disease is at an advanced stage and the majority are diagnosed when the disease is beyond the possibility of resection. On the other hand, GBCA can be discovered incidentally and appropriate oncologic surgery provides a great chance of cure for patients with GBCA. We present a case of incidentally-diagnosed GBCA and describe the surgical management for operable GBCA with a focus on the operative technique and perioperative management. A 60-year-old male presented with incidentally-discovered GBCA during a follow-up imaging study for his previously treated bladder cancer. The patient had been asymptomatic, and CT showed a growing mass in the gallbladder without evidence of metastatic disease. GBCA was suspected, and resection was recommended. He underwent extended cholecystectomy including cholecystectomy en bloc with partial hepatectomy at segment IVb and 5 and portal lymphadenectomy. His postoperative course was uneventful, and histologic examination confirmed the diagnosis of GBCA, pT3N1M0, stage IIIB.

Tenosynovitis of the peroneal tendons is a common lower extremity problem that is often mistaken for other ankle pathology. Diagnosis is suggested with thorough history and physical examination and confirmed with radiographic studies when necessary. Patients with less acute or more severe presentation may improve with rest and physical therapy alone. When conservative management fails, surgical intervention is aimed at excising inflamed synovium with debridement and repair of any tears in the peroneal tendons. Recent literature has emphasized the increased use of tendoscopic approaches to peroneal pathology, although most studies to date have been too underpowered to suggest superiority to an open approach. This article presents a case of acute tenosynovitis treated by open surgical debridement and irrigation. Tendoscopy was deferred as the size and nature of this patient’s injury warranted an open repair.

Total knee replacement is one of the most common orthopaedic procedures performed in the United States. The most common indication for total knee replacement is osteoarthritis. Clinical signs of knee osteoarthritis include pain with walking, difficulty ranging the knee, knee instability, varus deformity, bony enlargement, extension lag, and flexion contracture. Radiologic evidence for osteoarthritis of the knee includes the presence of osteophytes, joint space narrowing, subchondral sclerosis, subchondral cysts, and malalignment.

Before considering total knee replacement, patients typically undergo a trial of less invasive treatments, including lifestyle modification, pharmacologic therapy, and injections. If these methods fail to produce satisfactory improvement in the patient’s symptoms, one should consider the benefits and risks of total knee replacement in conjunction with their surgeon. Outcomes following total knee replacement are excellent, with patients reporting greatly reduced pain, improved mobility, and improved quality of life. However, patients must be aware that there are serious risks that accompany any surgery, which include infection, pulmonary embolism, deep vein thrombosis, nerve damage, and need for further procedures.

Urolithiasis is one of the most common and costly benign urologic conditions in the United States. While there are many options for managing urolithiasis ranging from conservative medical expulsive therapy to shockwave lithotripsy to percutaneous nephrolithotomy, ureteroscopy with laser lithotripsy is one of the most frequently performed minimally invasive urologic surgeries for treatment. In this video, we present a case of a patient with a ureteral stone that was treated with ureteroscopy, laser lithotripsy, and basket stone extraction. As part of the procedure, the patient also underwent a retrograde pyelogram and a ureteral stent exchange.

In neurosurgery, brain biopsy is an essential tool for providing adequate histological sampling in neoplastic and non-tumorous lesions. There are two main techniques in obtaining tissue samples: open biopsy requiring craniotomy or needle biopsy. Needle biopsies allow for minimally-invasive tissue diagnosis with less risk of operative morbidity for the patient. This video article show a frameless needle biopsy of a cerebellar lesion using the Brainlab varioguide system.

Femoral-to-popliteal/distal bypass surgery is a procedure used to treat femoral artery disease. It is performed to bypass the narrowed or blocked portion of the main artery of the leg, redirecting blood through either a transplanted healthy blood vessel or through a man-made graft material. This vessel or graft is sewn above and below the diseased artery such that blood flows through the new vessel or graft. The bypass material used can be either the great saphenous vein from the same leg or a synthetic polytetrafluoroethylene (PTFE) or Dacron graft.

This procedure is recommended for patients with peripheral vascular disease for whom medical management has not improved symptoms, for those with leg pain at rest that interferes with quality of life and ability to work, for non-healing wounds, and for infections or gangrene of the leg where there is a danger of loss of limb caused by decreased blood flow. This article demonstrates how to perform femoral artery cut-down and proximal anastomosis procedure in a cadaver. This procedure is commonly used when performing a femoral-popliteal below the knee bypass to restore blood flow to areas affected by arterial blockages or injuries․

Skin is the largest organ by surface area of the body and is essential to prevent dehydration as the first barrier to infection, permit unrestricted movement, and provide a normal profile and appearance. A skin graft is a paper-thin piece of skin that has no fat or other body tissues attached and has been completely removed from its blood supply. Therefore, a skin graft can be transferred anywhere in the body as long as where placed, the so-called recipient site, does have a sufficient blood supply to nourish the skin until new blood vessels can grow into it within a short timeframe. Otherwise, if that does not occur, the graft will shrivel up and die. The downside even of a successful skin graft is the variable final color and inharmonious appearance of the skin, a tendency to contract possibly causing deformities especially limiting motion across joints, and similar healing issues at a second wound, that is the donor site of the graft itself. Nevertheless, this is a rapidly performed surgical procedure requiring but the simplest of instrumentation for the harvest of that graft that can then permit replacement of extensive skin deficiencies. In this video article, these virtues are displayed as a split-thickness skin graft is used to replace the skin missing following the removal of a large squamous cell skin cancer of the forearm.

This video outlines the surgical steps involved in the microsurgical resection of an intracranial dural arteriovenous fistula (dAVF) in a 74-year-old male patient, highlighting the importance of meticulous planning, intraoperative imaging, and precise dissection techniques. The patient has previously undergone embolization, but recurrence occurred despite the initial treatment, and patient symptoms liked headaches and weakness restarted. A decision was made to perform microsurgical resection of dAVF. The video provides a comprehensive illustration of this procedure, emphasizing the value of microsurgery as a definitive treatment modality for these challenging clinical scenarios.

Ankle injuries are common, occurring most often among young males and older females. The ankle joint is crucial for stability and gait, making these injuries a significant source of disability.

Ankle injuries are usually treated operatively when there is loss of joint congruity and stability, and in this video, Dr. Agarwal-Harding takes us through the operative fixation of a bimalleolar ankle fracture. He talks about understanding why operative intervention is recommended, techniques involved, and other considerations.

The gold standard for achalasia is surgical correction via laparoscopic Heller myotomy with a partial fundoplication. The goal of this technical report is to illustrate the authors preferred approach to patients with achalasia and to provide the reader with a detailed description of his operative technique, its rationale, and preoperative and postoperative management.
