INNOVATING Realizing the promise of endoscopic technologies

The Center for Endoscopic Research and Therapeutics uses the most innovative endoscopic techniques to provide minimally invasive solutions for a range of gastrointestinal problems. Many of the advanced techniques we use were developed or perfected by our physicians, who strive constantly to push the boundaries of endoscopic technology for the benefit of patients. Our international reputation is based on consistent excellence at the leading edge of endoscopic practice: Advanced imaging techniques to identify precancerous conditions, sometimes even before they can be found with standard endoscopy. Endoscopic treatment of malignancies and obstruction of the GI tract and other complicated conditions, sparing patients from the risk of surgery. Precise endoscopic diagnosis and staging of cancer, enabling referring physicians to plan the most appropriate and effective surgical and oncological care. We are one of the only hospitals in the country to provide a comprehensive approach to treating benign pancreatic disease and our collective experience in complete endoscopic mucosectomy of Barrett’s esophagus is unmatched in the U.S. Many of the procedures we offer are available at only a select few institutions. These major differentiating procedures include include endoscopic submucosal dissection (ESD); extracorporeal shock wave lithotripsy (ESWL) for biliary pancreatic stones, and photodynamic therapy (PDT) for palliation of cholangiocarcinoma. 09


Endoscopic Submucosal Dissection Endoscopic submucosal dissection (ESD) can be considered minimally invasive intraluminal endoscopic surgery. ESD was developed in Japan as an alternative to standard surgical procedures to obtain en bloc removal of gastrointestinal (GI) neoplasias. En bloc resection is vital because it allows detailed histopathological evaluation of the entire resected neoplasm, and is associated with lower recurrence rates when compared to the loop-snare piecemeal technique, including traditional endoscopic mucosal resection. The ESD technique utilizes an electrosurgical knife to mark the margins of the lesion, mucosally incise around it, and cut through the submucosal layer underneath the lesion. Due to its increased technical difficulty, ESD is available only at a few selected quaternary care centers in the United States. Endoluminal resection is one of our main areas of research focus at CERT. We were one of the first groups in the nation to perform endoscopic mucosal resection (EMR). Our experience performing EMR spans 15 years and thousands of cases. Therefore, it is a natural evolution for us to now perform ESD. Indications for ESD include: Superficial esophageal cancer (both squamous or adenocarcinoma) Early gastric cancer Early colorectal cancer (limited to the superficial submucosa) Non-lifting colorectal lesions.

INNOVATING 10


Photodynamic Therapy for Cholangiocarcinoma Cholangiocarcinoma is a relatively rare cancer of the bile ducts with approximately 5,000 cases annually in the United States. Five-year survival rates average 5 to 10 percent. For more than 80 percent of patients, the disease is unresectable. Therapy options traditionally have been limited to chemotherapy and palliative bile duct stenting to relieve jaundice. In photodynamic therapy (PDT), the patient receives an IV porphyrin sensitizer 48 hours prior to endoscopic application of light to the tumor with the purpose of causing cell death. The light is delivered via a flexible fiber during endoscopic retrograde cholangiopancreatography (ERCP) at the time of biliary stent stent placement or exchange. Although data on the use of PDT in cholangiocarcinoma is limited, initial studies in patients with unresectable disease have suggested the treatment not only aids biliary decompression, but also improves survival through actual tumor destruction. The main side effect of this therapy is severe photosensitivity for 30 days for which the patient must be counseled. CERT is the only center in the city to offer PDT for therapy of unresectable cholangiocarcinoma and one of only a few centers nationwide invited to participate in an international, Food and Drug Administration approved PDT study.

11


Extracorporeal Shock Wave Lithotripsy Extracorporeal shock wave lithotripsy (ESWL) is a critically important tool in the endoscopic management of pancreatic biliary stones. Large stones in the main pancreatic duct can block the outflow of pancreatic secretions and exacerbate pain in patients with chronic pancreatitis, leading to poor quality of life, decreased PO intake, malnutrition and frequently the development of vitamin deficiency. Large stones can also contribute to additional complications, such as pancreatic ductal disruption, pseudocyst formation, pancreatic ascites, and pancreatic fistula. The pancreatic duct measures 2 mm to 4 mm in diameter, and stones in areas of stasis can grow to more than 1 cm. Therefore, it is impossible to remove these stones endoscopically without fragmenting them. Traditional therapies include direct electrohydraulic lithotripsy or direct laser therapy, both associated with significant complications; mechanical lithotripsy, which often is unsuccessful technically; and open surgery. ESWL targets shock waves to the large stones with the aid of fluoroscopy. The stones are fragmented into little pieces that can be extracted endoscopically or by a previous pancreatic sphincterotomy. The procedure is most effective in patients with head predominant disease. In one recent study (Tandan M, et al. GIE 2013) of 636 patients with chronic calcific pancreatitis who were treated with ESWL 60 percent were pain free eight years later. ESWL is contraindicated in patients with coagulation disorders, calcified aneurysm or lung tissue within the shock wave path. Severe complications such as acute pancreatitis are extremely rare. Other procedure-related findings of unclear clinical significance include elevated pancreatic enzymes, transient hematuria, and petechial lesions on the skin. The combination of ESWL and endoscopic therapy, which we perform the same day, alleviates pain in up to 85 percent of patients. In some cases, retreatment may be required. INNOVATING 12


Endoscopic Imaging

Our advanced imaging program and our experience in making difficult diagnoses mean we can offer you and your patient a more complete evaluation using multiple state-of-the-art modalities. We routinely integrate advanced imaging into our endoscopic procedures. These tools go far beyond the capability of traditional endoscopes to visualize the GI tract, providing information about tissue architecture, vascular patterns, and even microscopic-level detail. We have the most advanced options for recognizing subtle or occult precancerous changes in patients with diseases like Barrett’s esophagus and high-grade dysplasia. We often use two or three imaging modalities to examine the lining of the esophagus, beginning with a high-definition endoscope that produces images with a resolution in the range of a million pixels. We also regularly use narrow-band imaging, which uses filtered blue light that enables us to see and interpret mucosal pit patterns and vascular patterns. Our optical coherence-based technology allows us to see the superficial layers of the esophagus down to 3 mm deep with a resolution of 7 microns. We also can visualize cellular detail with a resolution down to 1 micron using probe-based confocal laser endomicroscopy (pCLE). We use this real-time microscopic imaging to see cellular detail throughout the entire GI tract, even in less accessible organs such as the bile ducts and pancreas. By using multiple advanced modalities, we reduce the chances of sampling error or missed lesions. We can perform an optical biopsy where we are able to accurately pinpoint cancerous and noncancerous cells in organ tissue without removing a tissue sample from the patient’s body. If we detect suspicious areas, we can make real-time decisions to take smarter biopsies and resections. We are pioneers in developing and incorporating the optical biopsy into clinical practice. Our team has participated in numerous clinical studies ranging from pilot trials using tools for the first time to international multicenter trials to validate novel imaging technologies for wider use. 13


ADVANCED CARE IN A STATE-OFTHE-ART PROCEDURE FACILITY

In CERT’s state-of-the-art endoscopy suite in the University of Chicago Medicine Center for Care and Discovery, patients benefit from the most advanced endoscopy technologies available. Procedures are performed under monitored anesthesia care (MAC) by a member of CERT’s core anesthesiology group. On-site pathology and cytopathology allow results to be shared immediately with referring physicians — in most cases, we can develop a plan of care for your patient before the patient leaves the endoscopy suite.

“Endoscopic techniques and technology are constantly advancing, and we treat more complex cases here than anywhere in the region.” DR. WAXMAN

Getting the Bile Flowing Again As a veteran pilot, Louis Freeman doesn’t take chances. When his wife told him in August 2013 that his itching could be a sign of liver trouble, he headed for the doctor. “Aside from the itching, I felt fine,” Freeman recalls, “no pain, no nausea, nothing. I had lost about 20 pounds, but then I was out there walking every day, trying to lose a little weight.” Freeman was found to have elevated liver tests by his internist and his original gastroenterologist told him he had jaundice but needed specialized endoscopic care for further evaluation. COLLABORATING 20


He said, “Within a couple of days, I was back on Dr. Waxman’s table at U of C” and was being worked up for possible cancer.

he did not have a malignancy, but instead had a rare benign condition called autoimmune sclerosing pancreatitis.

Dr. Waxman performed an endoscopic ultrasound (EUS) and found strictures not only of the common bile duct but also of the pancreatic duct. Then, using endoscopic retrograde cholangiopancreatography (ERCP), Dr. Waxman collected cells from the ducts to obtain a diagnosis, and then placed stents inside both biliary and pancreatic ducts. Freeman was relieved when Dr. Waxman informed him that

With his bile flowing again and steroids tackling the inflammation, Freeman was out of the woods, and he’s stayed there. “I was blessed,” he says. “I didn’t have the usual symptoms, but from my internist on down, I had doctors who took the extra steps to figure out what was really going on and send me to someone who could fix it.”


“A multidisciplinary team approach like ours is critical when you’re caring for patients with complex pancreatic diseases or complications from acute and chronic pancreatitis.” DR. GELRUD

Treating Pancreatitis Turned Deadly The words “There’s nothing more we can do” don’t usually precede a full recovery. Against all odds, for Kloe Salerno they did. First hospitalized for a relapse of childhood leukemia, Kloe received chemotherapy that triggered pancreatitis. Soon her liver showed signs of venoocclusive disease (VOD), and she developed GI bleeding. By the time the doctors had stopped the trial therapy for her liver, Kloe’s pancreatitis had turned deadly.

“She became septic. Her abdomen was filling with infected fluids. They kept saying they had seen pancreatitis before, but not like this,” says Brandi


Salerno, who stayed at her daughter’s side as they moved from hospital to hospital and specialist to specialist and the weeks turned into months.

assisted retroperitoneal debridement. It’s a novel procedure for the pancreas, but it’s how we saved her.”

That’s when Kloe’s aunt, searching the Internet, found Dr. Andres Gelrud and the team at UCM.

“Dr. Matthews, the surgeon, was superb. The interventional radiology team was superb, as well. It was just an incredible team effort.”

“When Brandi called us, we immediately devised a plan of care,” says Gelrud. “Kloe was so sick. She had a complete pancreatic ductal dysfunction, but I was able to do an ERCP and get it reconnected. I did a necrosectomy—we tried to work endoscopically as much as possible, but there was a huge walled-off necrosis and we needed the surgeons to go in and do a VARD, videoscopic

On January 24, 2015, the team’s extraordinary skill and experience paid off. For the first time in more than a year, Kloe and her mother went home. “I said I wasn’t going to leave the hospital without my daughter,” says Brandi. “Thanks to Dr. Gelrud and Dr. Matthews, I was able to keep that promise.”


Reopening a Nearly Closed Esophagus “CERT offers patients— and their referring physicians—a truly multidisciplinary treatment setting, with all the tools in place and the ability to try different approaches.” DR. KONDA

“Life is good. It really is.” Waymond Copeland’s treatment for stage IV throat cancer five years ago didn’t just leave him cancer free. It left him free to enjoy his life. Despite aggressive radiation, the 70-year-old doesn’t depend on a permanent feeding tube, and for that he is truly grateful. “I was pretty miserable,” he remembers. “I had to have IVs to stay hydrated, and that tube was just aggravating me. After three months, I was ready to have it out.”


With the help of Dr. Vani Konda, he was able to. Shortly after the radiation and chemo ended, she started Copeland on a series of treatments to reopen his nearly closed esophagus so that food could once again pass into his stomach and not his windpipe.

“Complex, radiation-induced strictures are much more persistent and challenging than others,” says Konda. “It takes patience and persistence, and a team approach to be prepared to handle difficult airways and anticipate the nutritional needs and expectations of the patient .”

Every two weeks at first, using balloons and flexible rods, Konda would coax open the passageway a few millimeters more. Steroids and mitomycin C helped break up the scar tissue, and within a few months, she was able to reduce the frequency of treatments to once a month, and then gradually to once a year or so, a schedule they maintain.

For Copeland and his wife, who recently returned from a 7-day Caribbean cruise, the results are worth it. “I love the water,” he says, “and with a cruise, you can always eat.” And that’s exactly what he did. “The food,” he says, “was fantastic.”


“We’re used to working together as a team, and each of us has more than 10 years experience dealing with the most complicated and complex cases.” DR. SIDDIQUI

Restoring a Young Man’s Health Ashley Summers calls her husband, Andy, “the luckiest unlucky guy I know.” It would be hard to disagree. What started as a simple gallstone attack progressed to necrotizing pancreatitis, then to a pseudocyst that twice became infected, and finally to a necrotic gallbladder. Andy’s lead physician, gastroenterologist Dr. Uzma Siddiqui, described his medical condition as potentially “life threatening.”

COLLABORATING 26

Fortunately, the 32-year-old construction worker had more than luck on his side. He had Ashley, who despite being “10 months pregnant” with their fourth child was both advocate and emotional support. And he had a superb medical team—


doctors not only skilled in performing surgery and endoscopic procedures but experienced enough to know when the very best option was to just sit tight. “They all knew my case every bit as well as Dr. Siddiqui did,” says Summers, “They would kind of bounce ideas off each other on whether to do another procedure or just let it set. It was wonderful.”

Her first task was to stabilize Summers, who had been transferred from Kankakee at Ashley’s request when his condition deteriorated. This meant to control his pain, get his electrolyte levels to baseline, and place a nasojejunal feeding tube. In subsequent weeks, she performed an endoscopic ultrasound-assisted cystogastrostomy to drain infected fluid from a pseudocyst on two occasions.

“It’s been a long road, but we have been so blessed,” “When dealing with severe necrotizing pancreatitis, says Ashley. “Through everything, Dr. Siddiqui just went way, way beyond what I ever anticipated. we always work closely with our surgical colleagues, and in Andy’s case we had the expertise She got him home for all the important stuff—for of our Chairman of Surgery, Dr. Jeffrey Matthews,” the baby, for Christmas. She got him home, and she got him well.” says Siddiqui.

EDUCATING Live endoscopy courses taught by internationally recognized experts We are committed to educating colleagues on how to use advanced endoscopic imaging and incorporate these technologies into their medical practices. CERT faculty members demonstrate their capabilities during two live endoscopy courses each year that attract attendees and faculty from around the world. Both are held in the University of Chicago Medicine Center for Care and Discovery. Our annual EUS LIVE course is one of the biggest endoscopy courses focusing on endoscopic ultrasound (EUS). The course, held in the fall, last year celebrated its 19th year of successful collaboration with Massachusetts General Hospital. The schedule included 24 lectures, 16 live cases, debates, two interactive quiz sections and a hands-on workshop. We were able to showcase not only master endoscopists from all over the world, but also our University of Chicago Medicine colleagues from pulmonary, surgery and pathology. Live from the University of Chicago! Endoscopic Advances for Clinical Practice, offered in the spring, outlines current standard practices in endoscopy and how innovations may enhance or revolutionize endoscopy practice in the future. The two-day course includes lectures, debates and live case demonstrations conduced by expert faculty from leading institutions. In addition to the two large CME courses, CERT faculty members routinely give lectures at conferences around the world. For information about upcoming CME opportunities, visit cme.uchicago.edu

EUS guidance was utilized to acquire blood from the portal vein of patients with suspected pancreaticobiliary cancers and completed circulating tumor cell (CTC) enumeration with direct comparisons to matched peripheral blood. We found 100% (12/12) patients had CTCs in the portal venous blood as compared to only 8.3% (1/12) in peripheral blood. Interestingly, even in patients with resectable and/or borderline resectable malignancy, CTCs were identified. In one case, we completed genomic analysis (CTNNB1 G34E missense mutation) in the isolated CTCs to confirm the source of cells to be the primary tumor. In this patient, we also completed immunofluorescent staining of tumor suppressor proteins (p53, smad4, p16) in individual CTCs during EPCAM flow cytometry via ImageStream technology.

This study establishes a novel role for EUS as it will be the first published report demonstrating that EUS guided sampling of the portal vein for CTCs is 1. Both feasible and safe and 2. Able to provide cells for tumor biology assessment that otherwise would not be possible from peripheral blood given hepatic sequestration of CTCs. As the management for non-metastatic, potentially curable pancreatic cancers continues to evolve, we believe EUS guided ‘realtime’ portal venous blood sampling has the potential to provide an adjunctive role in risk stratification identifying post-surgical recurrence, assessing response to neo-adjuvant therapies, and determining molecular features of tumor biology.

Our experience spans over a decade starting from when endoscopic resection was a novel technique in the esophagus to encompass a period where it is now standard therapy among several endoscopic treatment options. We have published on the efficacy and durability of complete endoscopic resection for Barrett’s associated neoplasia. Long term outcomes of endoscopic therapy such as this are critical in order to establish endoscopic therapy as standard therapy for these patients.

We’re one of a handful of hospitals in the country to offer total pancreatectomy with islet cell autotransplantation (autologous islet cell transplantation), a procedure aimed at preventing diabetes or reducing its effects after removal of the pancreas due to pancreatitis and severe pain. Minimizing, recognizing, and managing endoscopic adverse events. Gastrointest Endosc Clin N Am. 2015 Jan;25(1):xiii-xiv. This volume of GI Endoscopy Clinics of North America entitled “Minimizing, Recognizing, and Managing Endoscopic Adverse Events” is a comprehensive review of possible undesirable outcomes related to all types of endoscopic procedures. As the number of endoscopic procedures preformed continues to increase, so does the potential for adverse events (AE). Previous articles and endoscopy courses may have addressed a specific type of AE related to one or two endoscopic procedures, however this volume will explore the full range of endoscopic AE.

Philanthropic Partners CERT’s ambitious research agenda would not be possible without our donors’ strong commitment to improving patient care and outcomes. These generous individuals and organizations provide vital support as our physician-scientists investigate ways to advance the diagnosis and treatment of gastrointestinal cancers and other diseases through endoscopic discovery and innovation.

effective screening for esophageal cancer and creating a mouse model for the disease, which will enable researchers to study the interplay between diet and cancer risk.

During the past year, private philanthropy has supported Dr. Irving Waxman’s trials using endoscopic ultrasound rather than the current method of blood testing to identify and examine circulating tumor cells. This research could lead to earlier detection of pancreatic cancer and a better understanding of its prognosis to help patients and physicians make more informed choices about therapies. Philanthropy has also provided essential resources for Dr. Vani Konda’s recent projects, which include applying nanocytology to developing earlier and more
