Combination of concurrent endoscopic submucosal dissection and modified peroral endoscopic myotomy for an achalasia patient with synchronous early esophageal neoplasms

with an increased risk for developing esophageal squamous cell carcinoma. In our paper, we introduced an achalasia patient combined with synchronous early esophageal neoplasms. We performed a combination of concurrent endoscopic submucosal dissection (ESD) and peroral endoscopic myotomy (POEM). No complications other than postoperative pain that needed morphine treatment for two days had occurred. Dysphagia was significantly improved. Neither reflux nor cough occurred. The short-term efficacy and safety of our case is favorable and suggests that concurrent ESD and POEM could be a treatment option to such patients.

Ileal collision tumor associated with gastrointestinal bleeding: A case report and review of literature

BACKGROUND Collision tumors involving the small intestine,specifically the combination of a hamartomatous tumor and a lipoma,are extremely rare.To our knowledge,no previous case report has described a collision tumor composed of two benign tumors of different origins in the small intestine.CASE SUMMARY Here,we present the case of an 82-year-old woman who presented with hemorrhagic shock and was found to have a mass measuring approximately 50 mm×32 mm×30 mm in the terminal ileum.Based on computed tomography scan findings,the mass was initially suspected to be a lipoma.A subsequent colonoscopy revealed a pedunculated submucosal elevation consisting of two distinct parts with a visible demarcation line.A biopsy of the upper portion suggested a juvenile polyp(JP).Owing to the patient’s advanced age,multiple comorbidities,and poor surgical tolerance,a modified endoscopic submucosal dissection was performed.Histopathological examination of the excised mucosal mass revealed a lipoma at the base and a JP at the top,demonstrating evidence of rupture and associated bleeding.The patient’s overall health remained satisfactory,with no recurrence of hematochezia during the six-month follow-up period.CONCLUSION This case report provides new evidence for the understanding of gastrointestinal collision tumors,emphasizing their diverse clinical presentations and histopathological characteristics.It also offers diagnostic and therapeutic insights as well as an approach for managing benign collision tumors.

Early esophageal carcinomas in achalasia patient after endoscopic submucosal dissection combined with peroral endoscopic myotomy:A case report

BACKGROUND Achalasia is associated with high risk of esophageal carcinoma.However,the optimal endoscopic surgery for patients with early esophageal carcinoma concomitant with achalasia remains unclear.CASE SUMMARY A combination of concurrent endoscopic submucosal dissection(ESD)and modified peroral endoscopic myotomy(POEM)was performed on a 62-year-old male,who presented with multiple early esophageal carcinomas concomitant with achalasia.The patient exhibited an improvement in feeding obstruction,and presented no evidence of disease during the 3-year follow-up.CONCLUSION The combination of ESD and POEM is a feasible treatment modality for patients with early esophageal carcinoma concomitant with achalasia.

The Draf Ⅲ procedure: A review of indications and techniques

The DrafⅢprocedure involves the creation of a common frontal sinus cavity.The most common indication for the DrafⅢprocedure is chronic rhinosinusitis of the frontal sinuses despite the failure of more conservative interventions such as bilateral DrafⅡa procedures.Primary DrafⅢmay be indicated in patients with a high risk of failures such as those with severe polyposis and those with a frontal sinus opening less than 4 mm on computed tomography imaging.Other indications for the DrafⅢinclude access for tumor removal and repair of traumatic fractures of the frontal sinus.The"inside-out"DrafⅢprocedure is the standard approach when the frontal recess anterior-posterior diameter is wide enough for instrument access,usually larger than 4-5 mm.The"outside-in"DrafⅢprocedure can be done when the frontal recess is too narrow to safely accommodate instruments.Regular follow-up with debridement should be done to prevent neo-ostium stenosis.
