Oral endoscopic surgery

David E Rosow, Jamal Ahmed
Importance: Adult laryngotracheal stenosis (LTS) is typically managed surgically, but some patients fail treatment because of rapid restenosis or granulation tissue formation. The need for frequent surgery or tracheostomy reduces the quality of life in these patients and poses a significant challenge for the treating physician. New adjuvant treatments are required to reduce the surgical burden of this condition. Objective: To examine whether patients with rapidly recurrent nonvasculitic LTS who fail surgical management of their stenosis (ie, requiring dilation more frequently than every 6 months) experience longer intervals between surgical procedures when receiving adjuvant treatment with low-dose methotrexate...

BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

The treatment for achalasia changed dramatically after the introduction of minimally invasive surgery. Since 1991, laparoscopic Heller myotomy (LHM) has replaced pneumatic dilatation (PD) as the primary form of treatment in many centers. Over time, PD became safer, and eventually endoscopic experts were able to perform an endoscopic myotomy via a per oral endoscopic myotomy (POEM). This article reviews the advantages and disadvantages of each technique. Ultimately, the best outcomes are obtained by a multidisciplinary team that can tailor a specific treatment to each individual patient...

Chronic invasive nongranulomatous fungal rhinosinusitis is a well-described but uncommon type of fungal rhinosinusitis (FRS). While the prevalence of chronic FRS is 0.11% in healthy individuals, only 1.3% of them are in nongranulomatous invasive nature. The majority of the cases in the literature have been reported from developing countries mostly located in the tropical regions, as typically occurring in the background of diabetes mellitus or corticosteroid treatment. The current paper reports four consecutive cases, who were diagnosed within a short period of six months at a single center of a country located outside the tropical climate zone...

INTRODUCTION: Endoscopic thyroidectomy is a well-established surgical technique that is mainly performed for benign thyroid disease. We considered that endoscopic surgery could also be widely indicated for the treatment of thyroid cancer. We herein describe our new bidirectional approach of video-assisted neck surgery (BAVANS) for complete central node dissection in endoscopic thyroid cancer surgery. METHODS: BAVANS involves two different directional pathways to the cervical lesion...

Bilioenteric anastomosis strictures are a serious complication of biliary surgery, and often result in recurrent cholangitis, choledocholithiasis, biliary cirrhosis, and hepatic failure. Bilioenteric reconstructive surgery is the standard treatment of choice for such complications. However, percutaneous transhepatic cholangioscopy (PTCS), also known as per-oral endoscopic-guided intervention, is a less invasive procedure that is becoming an increasingly popular alternative. This review describes the PTCS procedure (including the preparation process), as well as the diagnostic and therapeutic role of PTCS in bilioenteric anastomosis strictures...

INTRODUCTION: Treatment of ovarian endometriomas is commonly achieved through laparoscopic surgery and this can be effective in eliminating the disease, although a majority of recent trials documented an adverse effect of surgery on ovarian reserve markers. With the advancement in imaging techniques, ovarian endometriomas are increasingly diagnosed at an earlier stage when the endometrioma may be smaller, less fibrotic and more responsive to medical treatment, making an evaluation of medical options critically important...

Between April 2013 and October 2015, 6 patients developed periampullary duodenal or jejunal/biliary leaks after major abdominal surgery. In all patients, percutaneous drainage of the collection or re-operation with primary surgical repair was attempted at first but failed. A fully covered enteral metal stent was placed in all patients to seal the leak. Subsequently, we cannulated the common bile duct and, in some cases, and the main pancreatic duct inserting hydrophilic guidewires through the stent after dilating the stent mesh with a dilatation balloon or breaking the meshes with Argon Plasma Beam...

Determining resection margins for gastric cancer, which are not exposed to the serosal surface of the stomach, is the most important procedure during totally laparoscopic gastrectomy (TLG). The aim of this protocol is to introduce a procedure for intraoperative gastroscopy, in order to directly mark tumors during TLG for gastric cancer in the middle third of the stomach. Patients who were diagnosed with adenocarcinoma in the middle third of the stomach were enrolled in this case series. Before surgery, additional gastroscopy for tumor localization is not performed...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and usually occur in the stomach and the small intestine. The pancreas is an extremely rare primary site for GISTs and there are 25 reported cases of pancreatic GIST with most being treated with surgical resection. We describe a 52-year-old African-American female who was diagnosed with limited stage small cell carcinoma in November 2009 and treated with concurrent cisplatin/etoposide chemotherapy and radiation...

BACKGROUND: Per oral endoscopic myotomy (POEM) is performed by accessing the submucosal space of the esophagus. This space may be impacted by prior interventions such as submucosal injections, dilations or previous myotomies. These interventions could make POEM more difficult and may deter surgeons during their initial experience. We sought to determine the impact of prior interventions on our early experience. METHODS: Prospective, single-center study of consecutive patients undergoing POEM...

Gastric cancer (GC) ranks fifth for cancer incidence and second for cancer deaths. Epidemiological data showed that survivors of Hodgkin's lymphoma and patients with pernicious anemia etiologically linked to autoimmune gastritis are at increased risk of GC. Screening of patients with autoimmune thyroid disease by means of pepsinogen (PG) I and PG I/II detected autoimmune gastritis with oxyntic gastric atrophy in one of four patients and may be recommended for GC prevention purposes. The International Agency for Research on Cancer reported a positive association between consumption of processed meet and increased GC risk...
