The technological advancements in the field of flexible endoscopy have allowed the endoscopist to perform more complex procedures with excellent outcomes and limited invasiveness. The current boundaries of what can be performed via an endoscope continue to be pushed further and is only limited by a physician's imagination. In this issue of Digestive Disease Interventions, we explore the edges of these boundaries and hope to offer a glimpse into the future of flexible endoscopy. We have invited world-renowned experts to provide their view on the current and future state of flexible endoscopy technologies and procedures. We began with a discussion of the more advanced endoscopic monitoring and tissue procurement devices. Readers will then be provided several articles focused on the endoscopic managements of both chronic and acute complications of surgical procedures such as enterocutaneous fistulas and bariatric complications. Finally, endoscopic managements of pathologies such as gastroparesis, achalasia, and gastroesophageal reflux disease will be explored. This issue of Digestive Disease Interventions will provide an excellent overview and reference for any physician interested in the more advanced techniques in flexible endoscopy.

Hidradenoma papilliferum is an uncommon, benign, cystic, papillary tumor that occurs almost exclusively in the female anogenital region. Bartholin's abscess is also an anogenital cystic lesion caused by obstruction of Bartholin's duct with an overlying infection. Concomitant presentation of Bartholin's abscess and Hidradenoma papilliferum is unique. A 43-year-old African American woman presented with a painful cystic mass on the left labia majora. A preoperative diagnosis of Bartholin's abscess was made. During excision and draining, an additional tan-brown dermal nodule was removed which demonstrated histological features of Hidradenoma papilliferum. We present what we believe to be the first case of Bartholin's abscess arising in hidradenoma papilliferum and its clinical significance.

Osteoarthritis is one of the most common causes of pain originating from the acromioclavicular (AC) joint. An awareness of appropriate diagnostic techniques is necessary in order to localize clinical symptoms to the AC joint. Initial treatments for AC joint osteoarthritis, which include non-steroidal anti-inflammatory drugs (NSAIDS) and corticosteroids, are recommended prior to surgical interventions. Distal clavicle excision, the main surgical treatment option, can be performed by various surgical approaches, such as open procedures, direct arthroscopic, and indirect arthroscopic techniques. When choosing the best surgical option, factors such as avoidance of AC ligament damage, clavicular instability, and post-operative pain must be considered. This article examines patient selection, complications, and outcomes of surgical treatment options for AC joint osteoarthritis.
