Laparoscopic sigmoid resection is indicated for disease of the distal sigmoid or rectum that requires resection, most notably diverticulitis and colorectal cancer. Here, we perform a sigmoid resection for diverticular disease. In this procedure, we used four laparoscopic port sites.
In the first step, we mobilized the splenic flexure and left colon to allow for a tension-free colorectal anastomosis low in the pelvis. Second, the mesorectum was dissected to mobilize the rectum down to the level of the pelvic floor. Third, the left colic and inferior mesenteric arteries were ligated, the colonic mesentery was transected with an energy device, and the distal resection margin was stapled intracorporeally. Fourth, the specimen was extracorporealized through the umbilical port site, and the proximal transection was performed. Finally, an anvil was inserted, and the colon was placed back into the abdomen where a trans-anal, stapled end-to-side Baker-type anastomosis was performed and endoscopically tested for leaks.
End stage renal disease (ESRD) is the final stage in the progression of chronic kidney disease (CKD). CKD has a multitude of etiologies, presents in a variety of ways, and progresses in a patient-dependent manner. Despite the heterogeneity of CKD, once ESRD ensues, patients require Renal Replacement Therapy (RRT). RRT is one of three prongs: hemodialysis, peritoneal dialysis, or kidney transplant.
Of these, kidney transplantation provides the patient with the best quality of life, an improved survival, and an opportunity for cure. However, the success of kidney transplantation with improved outcomes and tolerance to the required immunosuppression has led to an extreme organ shortage despite the increase in deceased organ donors. As a result, the push for living donors has become increasingly more important.
For recipients, the best outcomes are with transplants from a living donor due to superior graft quality and elimination of the need for waiting and dialysis. This article will present such a case and discuss the important considerations a physician must make preoperatively and intraoperatively when performing kidney transplantations.
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.
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.
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.

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.
