Obstructive sleep apnea (OSA) is a common condition with several effective treatment strategies centered around relieving airway obstruction. The gold standard for OSA treatment remains continuous positive airway pressure (CPAP), but other options exist.

A recent therapy developed within the past decade utilizes hypoglossal nerve stimulation (HGNS) through a surgically implanted device. As the patient inspires, the device sends an electrical impulse similar to a cardiac pacemaker. The impulse activates targeted branches of the hypoglossal nerve, leading to stimulation of muscles that protrude the tongue and open the airway posteriorly. This mechanism has been shown to reduce airway obstruction by activating these muscles during inspiration.

Along with detailing the chronological order of events, this case outlines various complex anatomical structures that are identified in order to safely and effectively implant the hypoglossal nerve stimulator.

Gallstone disease is one of the most common disorders affecting the digestive tract. Most individuals with gallstones are asymptomatic and do not require treatment. For symptomatic patients, however, cholecystectomy is recommended.

Cholecystectomy is one of the most common abdominal surgeries performed worldwide. Indications include moderate-to-severe symptoms, stones obstructing the bile duct, gallbladder inflammation, large gallbladder polyps, and pancreatic inflammation due to gallstones.

Here, we report the case of a 53-year-old male with stones in his biliary duct. Despite having uncomplicated disease, the patient was treated with a primary open cholecystectomy because laparoscopy was not available.

This case consists of repairing an extensor tendon laceration of a thumb. Extensor tendon lacerations are one of the most common soft tissue injuries of the hand. Surgical repair of the tendon was offered, and the operation was performed using wide-awake local anesthesia no tourniquet (WALANT) technique.

Intraoperatively, a complete laceration of the extensor tendon was confirmed repaired using a modified Kessler technique and reinforced with an epitendinous repair. Before closure, the patient tested competency of the repair with confirmation of restoration with the active extension to ensure proper function. The patient was placed in a reverse thumb spica splint following wound closure.

Postoperatively, the patient was immobilized in full thumb extension for approximately two weeks and then converted to a removable splint and prescribed supervised hand therapy for a total recovery of 8–12 weeks.

Lipomas are slow-growing lumps that occur as a result of overgrowth of fat cells. They present as doughy, moveable, and non-tender lumps usually found underneath the skin; however, they may occasionally be deeper. Lipomas occur in 1 in every 1,000 people and commonly grow on the upper back, shoulders, and abdomen. In most cases, lipomas are painless unless they affect joints, nerves, or blood vessels. A physical examination is the easiest way to diagnose a lipoma; however, imaging studies and biopsy may aid in the diagnosis when they are large, have unusual features, or appear deep.

No treatment is usually necessary for a lipoma; however, if a lipoma is painful or growing, removal may be recommended by excision or liposuction. Here, we present a 35-year-old male who has a large and deep 8-year-old lipoma on his upper back. The lipoma was excised and sent for biopsy.

Anorectal abscesses most commonly result from obstruction of glandular crypts in the anorectal canal. Abscesses are commonly diagnosed by clinical exam with fluctuance, induration, and tenderness around the perianal tissue.

Abscesses are managed with incision and drainage. For superficial perianal abscesses, bedside lancing can be performed, but for more complex or ischiorectal or postanal abscess, examination under anesthesia in the operating room is preferred. Complete evacuation of the abscess with breakdown of loculated abscess pockets is critical to fully control the infection. Drains may also be left in a deep abscess pocket to prevent the skin prematurely closing before the cavity has healed.

Imaging is selectively performed with CT or MRI to identify occult infections or further identify proximal extent of abscess cavity or associated fistula. For recurrent abscesses, associated fistula tracts should also be identified and, if possible, treated intraoperatively. Antibiotics are utilized for patients with cellulitis or those who are immunosuppressed. This video article presents an adult male with recurrent anorectal abscesses with a new anterior abscess collection, which was managed with anal exam under anesthesia with incision and drainage of abscess collection and drain placement.

Most individuals associate anal pain with hemorrhoids. However, there are many conditions that can cause anal pain and bleeding, and physical examination helps to differentiate between these diagnoses: anal fissures, hemorrhoids, or infections.

An anal fissure is a superficial tear in the anoderm. Fissures are diagnosed clinically by history and physical exam with careful spreading of the anus and direct visualization of a break in the mucosa and exposed sphincter fibers. Increased tone of the internal anal sphincter can inhibit fissure healing by decreasing blood flow to the mucosa.

Conservative management includes stool softeners and warm sitz baths to avoid traumatizing the fissure with hard stools and relaxing the sphincters with warm water. Topical nitrates or calcium channel blockers applied at the anal verge dilate and relax the internal sphincter muscle to promote healing.

Alternatively, injection of Onobotulinumtoxin A into the fissure and intersphincteric groove paralyzes sphincter muscle, decreasing muscle spasm and supporting healing of the fissure. For individuals who fail these conservative therapies, lateral internal sphincterotomy is considered. This procedure involves dividing the internal sphincter muscles but carries a small risk of fecal incontinence.

This video article presents the case of a young adult male with a history of a chronic anal fissure, who failed medical management. Anal fissure was appreciated on exam and treated with Onobotulinumtoxin A injection for relaxation of anal sphincter.

Laparoscopic low anterior resection (LAR) is a complex surgical procedure used for resecting the distal sigmoid colon or rectum while preserving sphincter function. The patient is a 37-year-old, obese male with rectal cancer.

Abdominal access is gained through four laparoscopic port sites. The omentum is freed from the transverse colon to enter the lesser sac. The splenic flexure and descending colon are mobilized from the retroperitoneum. The left colic artery is identified and divided. Following proximal mobilization, the dissection is carried towards the pelvis. The sigmoid colon is mobilized, and the presacral space is entered. The inferior mesenteric artery is divided between clips. The dissection in this case could not be carried down low enough in a laparoscopic fashion, and a lower midline incision was made. A suitable area on the descending colon is identified and the marginal artery divided. The proximal bowel is then divided with a stapler. A flexible colonoscope is then used to confirm tumor location and the rectum is divided below the tumor. Finally, a Baker type side-to-end anastomosis is performed with a powered EEA stapler, and its integrity verified endoscopically under water. A diverting loop ileostomy is then created at a previously marked site and the abdomen closed.

In this video, the surgical steps of this procedure are demonstrated and insight is provided into intraoperative decisions.

A hiatal hernia occurs when part of an intra-abdominal organ, most commonly the stomach, migrates through the diaphragmatic crura. The condition can cause a range of uncomfortable symptoms, including heartburn, chest pain, and difficulty swallowing. While several individuals with a hiatal hernia can manage their symptoms with lifestyle changes and anti-reflux medications, some with refractory symptoms or complications secondary to the hernia require surgical treatment to repair the defect.

Here we present the case of a 60-year-old female with a paraoesophageal hiatal hernia and chronic gastrointestinal reflux disease (GERD) refractory to proton-pump inhibitors (PPI), dietary changes, and lifestyle modifications. She underwent an elective robotic hiatal hernia repair, fundoplication, and esophagogastroduodenoscopy (EGD) as a two-hour procedure with routine postprocedure recovery. This article and the associated video describe the pertinent history, evaluation, and operative steps of the procedure.

Hip arthroscopy with femoral neck or acetabular osteoplasty with or without labral repair can be used for treatment of femoroacetabular impingement (FAI). Patients may present with insidious onset of hip pain and mechanical symptoms and pain worse with activity and sitting.

On physical exam hip flexion and internal rotation may be reduced and anterior impingement testing will produce groin pain in the majority of patients with FAI. Imaging may demonstrate lesions responsible for cam-type or pincer-type impingement, and MRI may demonstrate labral tear or cartilaginous lesions. Arthroscopic surgical treatment is indicated for patients who have failed conservative treatment.

Fistula-in-ano is a chronic abnormal communication between the anal canal and, usually, the perianal skin. It can be described as a hollow tract that is lined with granulation tissue and connects a primary opening inside the anal canal to a secondary opening in the perianal skin. It usually originates from the anal glands and is frequently the result of a previous anal abscess. Anal fistulae present with pain, swelling, pruritus, skin irritation, and purulent or bloody drainage. Most anal fistulae are diagnosed based on clinical findings, but complex and deep anal fistulae usually require imaging studies such as CT scan or MRI to delineate the tract.

Currently, there is no medical treatment available and surgery is almost always necessary. A simple intersphincteric fistula can often be treated with fistulotomy or fistulectomy, while trans-sphincteric and suprasphincteric fistulae are treated by placement of a seton to maintain drainage and induce fibrosis. Extrasphincteric fistula treatment depends on the anatomy and etiology of the fistula.

This article presents the case of a 1-year-old male with a history of recurrent perianal infection, which led to the development of an anal fistula. The anal fistula was noted to be superficial, and a fistulotomy was performed.
