- Background
/Aims: A new medical fiber-guided diode laser system (FDLS) is expected to offer high-precision cutting with simultaneous hemostasis. Thus, this study aimed to evaluate the feasibility of using the 1,940-nm FDLS to perform endoscopic submucosal dissection (ESD) in the gastrointestinal tract of an animal model.
Methods
In this prospective animal pilot study, gastric and colorectal ESD using the FDLS was performed in ex vivo and in vivo porcine models. The completeness of en bloc resection, the procedure time, intraprocedural bleeding, histological injuries to the muscularis propria (MP) layer, and perforation were assessed.
Results
The en bloc resection and perforation rates in the ex vivo study were 100% (10/10) and 10% (1/10), respectively; those in the in vivo study were 100% (4/4) and 0% for gastric ESD and 100% (4/4) and 25% (1/4) for rectal ESD, respectively. Deep MP layer injuries tended to occur more frequently in the rectal than in the gastric ESD cases, and no intraprocedural bleeding occurred in either group.
Conclusions
The 1,940-nm FDLS was capable of yielding high en bloc resection rates without intraprocedural bleeding during gastric and colorectal ESD in animal models.

- Background
/Aims: Frequent bleeding after endoscopic resection (ER) has been reported in patients with end-stage renal disease (ESRD). We aimed to evaluate the association and clinical significance of bleeding with ER in ESRD patients on dialysis.
Methods
Between February 2008 and December 2018, 7,571 patients, including 47 ESRD patients on dialysis who underwent ER for gastric neoplasia, were enrolled. A total of 47 ESRDpatients on dialysis were propensity score-matched 1:10 to 470 non-ESRD patients, to adjust for between-group differences in variables such as age, sex, comorbidities, anticoagulation use, tumor characteristics, and ER method. Matching was performed using an optimal matching algorithm. For the matched data, clustered comparisons were performed using the generalized estimating equation method. Medical records were retrospectively reviewed. Frequency and outcomes of post-ER bleeding were evaluated.
Results
Bleeding was more frequent in the ESRD with dialysis group than in the non-ESRD group. ESRD with dialysis conferred a significant risk of post-ER bleeding (odds ratio, 6.1; 95% confidence interval, 2.7–13.6; p<0.0001). All post-ER bleeding events were controlled using endoscopic hemostasis except in 1 non-ESRD case that needed surgery.
Conclusions
ESRD with dialysis confers a bleeding risk after ER. However, all bleeding events could be managed endoscopically without sequelae. Concern about bleeding should not stop endoscopists from performing ER in ESRD patients on dialysis.

- Endoscopic submucosal dissection (ESD) is a standard treatment for patients with gastrointestinal neoplasms with a negligible risk of lymph node metastasis. ESD enables en bloc resection of gastrointestinal neoplasms and organ preservation, thereby, avoiding surgical treatment. Although small (<2 cm) intramucosal early gastric cancer with undifferentiated-type histology (EGC-UH) without ulceration is included in the expanded criteria for ESD, controversies remain due to different biology and characteristics compared to EGC with differentiated-type histology. The authors previously presented studies about the technical feasibility of ESD for these lesions using a meta-analysis and retrospective multicenter analysis. However, many pitfalls were identified in the interpretation of studies analyzing histologic discrepancy, mixed-type histology, criteria-based analysis of therapeutic outcomes, interpretation of curative resection, and long-term clinical outcomes. In this review, the authors discuss pitfalls in the interpretation of publications on ESD for EGC-UH.

- Background
/Aims: To assess the therapeutic outcomes of endoscopic resection (ER) of early gastric cancer (EGC) with undifferentiated-type histology.
Methods
Cases of ER of EGC with undifferentiated-type histology in the Korean endoscopic submucosal dissection (ESD) registry database were identified and reviewed. The immediate outcomes, including en bloc resection, complete resection, and curative resection rates, and long-term outcomes, including recurrence and survival rates, were extracted and analyzed.
Results
From 2006 to 2015, 275 EGCs with undifferentiated-type histology from 275 patients were identified. The immediate outcomes were as follows: en bloc resection rate: 92.4%; complete resection rate: 80%; and curative resection rate: 36.4%. Compared to patients with lesions that were beyond the expanded indication, those with expanded indication lesions showed better therapeutic outcomes. There was no difference in immediate outcomes between patients with poorly differentiated adenocarcinoma (PDC) and signet ring cell carcinoma (SRC). However, compared to ER of SRC, ER of PDC had a stronger association with submucosal invasion (41.9% vs. 23.6%, p=0.003). With regard to long-term outcomes, there was no difference between lesions with curative and non-curative resections in the recurrence and mortality rates. These rates also did not differ between PDC and SRC (median follow up: 3.96 years).
Conclusions
ER confined to expanded indication lesions can be considered for treatment of EGC with undifferentiated-type histology.

- Intravesical bacillus Calmette-Guérin (BCG) immunotherapy is a common treatment modality for bladder cancer after transurethral resection of a bladder tumor. This therapy is generally safe, and development of a prostatic abscess with a prostatorectal fistula after intravesical BCG immunotherapy is a very rare complication. This finding was incidentally obtained by the authors, who examined a patient with colonoscopy for evaluation of abdominal pain. The patient was successfully treated with antitubercular drugs. To the authors’ knowledge, this is the first report of a patient with a tuberculous prostatic abscess with prostatorectal fistula after BCG immunotherapy in South Korea.

Xanthoma is an uncommon nonneoplastic lesion resulting from the accumulation of histiocytes. It predominantly shows cutaneous manifestations associated with dyslipidemia. However, xanthoma of the esophagus is extremely rare. To the best of our knowledge, only 14 cases have been reported thus far. The clinical significance of this lesion has not been established. However, this lesion should be distinguished grossly from ectopic sebaceous glands and small subepithelial tumors such as carcinoid and granular cell tumor. Moreover, signet ring cell carcinoma, which contains round cells with abundant cytoplasm and has similar histologic features to xanthoma, should be distinguished microscopically.

Colonic lipomas, which often occur in elderly women, usually have small size and occur mainly in the cecum and ascending colon. Most colonic lipomas are asymptomatic and identified incidentally at the time of endoscopy or surgery. However, they may cause symptoms such as bleeding, obstruction or intussusception as their size increases. Intermittent episodes of intussusception are uncommon but may be caused by large pedunculated lipoma. In a 68-year-old woman suffering intermittent abdominal pain, 5.5×4.5×3.8-cm huge mass was found by colonoscopy at proximal ascending colon, which was intussuscepted to proximal transverse colon on abdominal computed tomography. Segmental right colonic resection was conducted. We report a case of symptomatic giant pedunculated colonic lipoma causing intussusception requiring surgical intervention, with a successful recovery after surgery.
