Pyloric stenosis resulting in gastric outlet obstruction can present with nausea, vomiting, and early satiety. Imaging including fluoroscopic upper gastrointestinal series and computed tomography can diagnose gastric outlet obstruction. Upper endoscopy is included in the work-up to visualize the extent of stenosis and to obtain a tissue biopsy. After a malignancy is ruled out, treatment involves management of underlying causes.
This may include acid suppression, treatment of H. pylori, and dietary modification. Patients who fail conservative management may benefit from endoscopic therapies including pneumatic dilation and botulinum toxin injection. However, these therapies may not offer lasting symptomatic relief.
Pyloroplasty can be performed with the goal of widening the pylorus to improve gastric emptying. Pyloroplasty can be accomplished through open, laparoscopic, and robotic techniques. Here we describe a robotic-assisted Heineke-Mikulicz pyloroplasty in an adult patient with benign pyloric stenosis.
There is no consensus on the optimal method of ventral hernia repair, and the choice of techniques is typically dictated by a combination of patient factors and surgeon expertise. Component separation techniques allow medial advancement of the rectus abdominis muscle to create a midline tension-free fascial closure.
In this case, we describe a posterior component separation with retrorectus mesh placement, also known as a Rives-Stoppa retromuscular repair. With low morbidity and mortality, this technique provides a durable repair with low rates of recurrence and surgical site infection while providing dynamic muscle support and physiologic tension, preventing eventration, and allowing incorporation of mesh into the existing abdominal wall.

Benign prostatic hyperplasia (BPH) is a common condition affecting the majority of men over 60 years of age. BPH incidence increases with age and often leads to lower urinary tract symptoms including frequency, urgency, and straining. In patients that do not respond to pharmacological therapy, options include transurethral procedures such as transurethral resection (TURP) or photovaporization, surgical prostatectomy, and prostate artery embolization (PAE).
The goal of PAE is to occlude arterial supply to the prostate by selective catheterization and subsequent embolization, most commonly with spherical tris-acryl gelatin microspheres. Over weeks to months, reduced blood flow leads to necrosis of prostatic adenomatous tissue, resulting in reduction of prostate size and decreased urethral impingement, eventually allowing for long-term resolution of symptoms in a majority of patients. Advantages of this technique compared with the standard surgical option, TURP, include faster recovery times, fewer side effects, and lower complication rates with near equal efficacy.

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.
Thumb Extensor Tendon Laceration Repair Evan Bloom1; Amir R. Kachooei, MD, PhD2; Asif M. Ilyas, MD, MBA, FACS1,2 1 Sidney Kimmel Medical College at Thomas Jefferson University 2 Rothman Institute at Thomas Jefferson University
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.
