Expanding endoscopic boundaries:Endoscopic resection of large appendiceal orifice polyps with endoscopic mucosal resection and endoscopic submucosal dissection

BACKGROUND Large appendiceal orifice polyps are traditionally treated surgically.Recently,endoscopic mucosal resection(EMR)and endoscopic submucosal dissection(ESD)have been utilized as alternative resection techniques.AIM To evaluate the efficacy and safety of endoscopic resection techniques for the management of large appendiceal orifice polyps.METHODS This was a retrospective observational study conducted to assess the feasibility and safety of EMR and ESD for large appendiceal orifice polyps.This project was approved by the Baylor College of Medicine Institutional Review Board.Patients who underwent endoscopic resection of appendiceal orifice polyps≥1 cm from 2015 to 2022 at a tertiary referral endoscopy center in the United States were enrolled.The main outcomes of this study included en bloc resection,R0 resection,post resection adverse events,and polyp recurrence.RESULTS A total of 19 patients were identified.Most patients were female(53%)and Caucasian(95%).The mean age was 63.3±10.8 years,and the average body mass index was 28.8±6.4.The mean polyp size was 25.5±14.2 mm.74%of polyps were localized to the appendix(at or inside the appendiceal orifice)and the remaining extended into the cecum.68%of polyps occupied≥50%of the appendiceal orifice circumference.The mean procedure duration was 61.6±37.9 minutes.Polyps were resected via endoscopic mucosal resection,endoscopic submucosal dissection,and hybrid procedures in 5,6,and 8 patients,respectively.Final pathology was remarkable for tubular adenoma(n=10)[one with high grade dysplasia],sessile serrated adenoma(n=7),and tubulovillous adenoma(n=2)[two with high grade dysplasia].En bloc resection was achieved in 84%with an 88%R0 resection rate.Despite the large polyp sizes and challenging procedures,89%(n=17)of patients were discharged on the same day as their procedure.Two patients were admitted for post-procedure observation for conservative pain management.Eight patients underwent repeat colonoscopy without evidence of residual or recurrent adenomatous polyps.CONCLUSION Our study highlights how endoscopic mucosal resection,endoscopic submucosal dissection,and hybrid procedures are all appropriate techniques with minimal adverse effects,further validating the utility of endoscopic procedures in the management of large appendiceal polyps.

Vascular Graft Bridged En Bloc Resection for Biliopancreatic Cancer Invading the Portal System

To meet the requirement of extensive resection of pancreatic cancer with portal or mesenteric venous invasion,the innovation of Vascular Graft Bridged En Bloc Resection （VGBEBR） has been adopted to treat advanced biliopancreatic cancer in the Department of Hepatobiliary Surgery of the PLA Rocket Force General Hospital since 2013.This attempt could not only broaden surgical indications of radical resection and lymphadenectomy but also increase R0 resection rate,especially for the case with severe invasion in the portal and mesenteric venous system.

Transpedicular osteotomy en bloc lamina resection for the treatment of thoracic spinal stenosis

Objective To study the safety and efficacy of transpedicular osteotomy en bloc lamina resection to treat thoracic spinal stenosis.Methods A retrospective study of 23 consecutive patients underwent transpedicular osteotomy en bloc lamina

Rare primary rectal mucosa-associated lymphoid tissue lymphoma with curative resection by endoscopic submucosal dissection:A case report and review of literature

BACKGROUND Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue(MALT lymphoma)occurs in approximately 9%of non-Hodgkin B-cell lymphomas.The gastrointestinal tract is the most commonly affected site of the extranodal forms of primary non-Hodgkin’s lymphomas.However,it rarely occurs within the rectum,and at present,there is no consensus on its diagnosis and treatment at this site.CASE SUMMARY We report a rare laterally spreading tumour-like rectal MALT lymphoma case in which the diagnosis and the depth of infiltration were determined by magnifying endoscopy and ultrasonic endoscopy.Then,the lesion was en bloc resected by endoscopic submucosal dissection(ESD)alone.The lesion was confirmed as MALT lymphoma by haematoxylin and eosin staining,immunohistochemical staining and gene arrangement analysis.Surveillance exams have indicated a 2-year disease-free survival for this patient.CONCLUSION We report a rare primary rectal MALT lymphoma that was curable with resection by ESD.ESD is a safe and effective therapeutic option for rectal MALT lymphoma.

Thulium laser treatment for bladder cancer

Recent innovations in thulium laser techniques have allowed application in the treatment of bladder cancer.Laser en bloc resection of bladder cancer is a transurethral procedure that may offer an alternative to the conventional transurethral resection procedure.We conducted a review of basic thulium laser physics and laser en bloc resection procedures and summarized the current clinical literature with a focus on complications and outcomes.Literature evidence suggests that thulium laser techniques including smooth incision,tissue vaporization,and en bloc resection represent feasible,safe,and effective procedures in the treatment of bladder cancer.Moreover,these techniques allow improved specimen orientation and accurate determination of invasion depth,facilitating correct diagnosis,restaging,and reevaluation of the need for a second resection.Nonetheless,large-scale multicentre studies with longer follow-up are warranted for a robust assessment.The present review is meant as a quick reference for urologists.

Recurrence of intratendinous ganglion due to incomplete excision of satellite lesion in the extensor digitorum brevis tendon: A case report

BACKGROUND Intratendious ganglions are rare lesions, especially on the foot and ankle. Although several studies have presented the intratendinous ganglion of the foot and ankle, there are only few reported cases, and no cases of recurrence or secondary surgery have been reported.CASE SUMMARY We present the case of a 32-year-old man with an intratendinous ganglion of the second extensor digitorum brevis(EDB) tendon that recurred after ganglion excision. Magnetic resonance imaging(MRI) performed before the first surgery was reviewed to analyze the causes of the recurrence. We confirmed that there was a lack of satellite detection. After recurrence, MRI revealed an extratendinous lesion, tenosynovitis, and intratendinous ganglion of the second EDB tendon. Since the second EDB tendon can compensate for the extrinsic muscle, en bloc resection was performed alone. In addition, meticulous excision and synovectomy were performed for extra-tendinous lesions and tenosynovitis, respectively. The patient returned to daily life without any functional problems or recurrence.CONCLUSION If removal of the affected tendon is not fatal, en bloc resection should first be considered to prevent incomplete excision and intraoperative leakage. When planning surgical excision, it is necessary to evaluate the presence of satellite lesions along the course of the affected tendon.

Parathyroid carcinoma initiated by hypercalcemic crisis

Parathyroid carcinoma （PC） is a rare neoplasm that accounts for 0. 1%-5% of primary hyperparathyroidism cases. Hyperparathyroidism-induced hypercalcemic crisis （HHC） is sometimes due to a single PC.1 However,
