Tuberculosis (TB) once considered a disease of the developing world is infrequent in the developing world too. Its worldwide prevalence with a huge impact on the healthcare system both in economic and health terms has prompted the World Health Organization to make it a top priority infectious disease. Tuberculous infection of the pulmonary system is the most common form of this disease, however, extrapulmonary TB is being increasingly recognized and more often seen in immunocompromised situations. Gastrointestinal TB is a leading extrapulmonary TB manifestation that can defy diagnosis. Overlap of symptoms with other gastrointestinal diseases and limited accuracy of diagnostic tests demands more awareness of this disease. Untreated gastrointestinal TB can cause significant morbidity leading to prolonged hospitalization and surgery. Prompt diagnosis with early initiation of therapy can avoid this. This timely review discusses the epidemiology, risk factors, pathogenesis, clinical presentation, current diagnostic tools and therapy.

Usefulness of Routine Plain CT the Day After an Interventional EUS Procedure
p. 275
Aya Kiyanagi, Toshio Fujisawa, Shigeto Ishii, Ko Tomishima, Yusuke Takasaki, Akinori Suzuki, Mako Ushio, Sho Takahashi, Wataru Yamagata, Yoshihiro Okawa, Kazushige Ochiai, Hiroaki Saito, Hiroyuki Isayama

PMID
:34380872
Background:
Interventional endoscopic ultrasound-guided procedures (I-EUS) are widely accepted as salvage procedures in ERCP-failed cases, and to drain fluid collected in the abdominal cavity. Although I-EUS has a relatively high incidence of complications and is severe/fatal in some cases, no follow-up strategy has been established. In our institution, plain computed tomography (P-CT) is performed routinely the day after I-EUS. In this study, we evaluated the usefulness of routine P-CT the day after I-EUS, as a follow-up method, and propose an algorithm.
Methods:
We retrospectively reviewed 81 patients who underwent I-EUS and evaluated the usefulness of P-CT, abdominal X-ray, laboratory data, and symptoms as a follow-up method. An adverse event (AE) was defined as an event requiring any treatment.
Results:
Technical success, clinical success, and AE rates were 96.3%, 90.1%, and 18.9%, respectively. In total, 30 patients had abnormal findings among the follow-up methods: 6 cases underwent additional procedures, 8 underwent medical treatments, and 16 were observed. The sensitivity, specificity, and accuracy for detecting AEs were assessed based on P-CT (85.7%, 100%, and 97.5%), X-ray (7.1%, 100%, and 83.5%), laboratory data (71.4%, 83.0%, and 81.0%), and symptoms (92.9%, 86.2%, and 87.3%). The sensitivity and accuracy of the latter two items were as high as those for X-ray, but specificity was lower than those for X-ray and P-CT.
Conclusions:
Routine P-CT the day after I-EUS was useful for detecting complications and deciding to perform an invasive salvage procedure. Symptoms and laboratory data were useful to supplement routine P-CT.

EUS-guided drainage of pancreatic fluid collection, using a modified technique of cystotome alone without a FNA needle
p. 283
Praveer Rai, KC Harish, Abdul Majeed, Amit Goel
DOI
:10.4103/sjg.sjg_132_21
PMID
:34677161
Background:
Endoscopic ultrasound (EUS)-guided drainage for pancreatic fluid collection (PFC) involves puncture with a fine-needle aspiration (FNA) needle, followed by tract dilation involving exchange of multiple accessories, and finally deployment of stent. The procedure is time consuming and carries a risk of loss of wire access and hence technical failure. We used a modified technique with a 10-F cystotome alone instead of a FNA needle and dilators.
Methods:
We retrospectively analysed records of consecutive patients who had undergone EUS-guided drainage of PFC using a modified technique, with puncture of PFC using a 10-Fcystotome, followed by passage of a guidewire through it into the PFC cavity and deployment of a biflanged, 2-cm-long, fully covered self-expanding metal stent over it. Technical and clinical success rates and procedure time were assessed.
Results:
Forty-five patients underwent PFC drainage, median age was 35 (12–76), and 35 (77.8%) were males. The median (range) duration of symptoms was 125 (38–1080) days, while the median PFC size was 11.8 × 11 × 11 cm, and the follow-up period after stent removal was 111 ± 72 (18–251) weeks. The procedure took 10 (8–12) min and had technical and clinical success rates of 100 and 97.8%, respectively. Minor complications occurred in six (13.3%) patients, while recurrence occurred in one.
Conclusion:
EUS-guided drainage of PFC using a cystotome is a quick, effective and safe procedure. It may also be less expensive since it obviates the use of FNA needles and dilators, and is likely to be a useful alternative to the conventional technique.

Is there any link between atrial arrhythmias and inflammatory bowel disease?
p. 289
Güray Can, Nergis Ekmen, Hatice Can, Muhammet Fatih Bayraktar, Muhammed Emin Demirkol, Meral Akdoğan Kayhan, Hadi Sasani
DOI
:10.4103/sjg.sjg_622_20
PMID
:34596593
Background:
Inflammation plays an important role in the development of cardiovascular disease, including atherosclerosis and arrhythmia. The aim of this study was to evaluate atrial conduction times (ACTs) in patients with inflammatory bowel disease (IBD) in which systemic chronic inflammation is evident.
Methods:
In this cross-sectional, prospective, single-center study, 79 IBD patients (51 ulcerative colitis; 28 Crohn's disease) and 70 healthy controls were included. Atrial electromechanical properties were measured by recording simultaneous surface electrocardiography (ECG) with transthoracic echocardiography (ECHO) and tissue Doppler imaging methods. The relationship between age, disease duration, and ACT was evaluated.
Results:
There were significantly increased conduction durations of lateral-PA (time interval from the onset of the P-wave on surface ECG to the beginning of the late diastolic wave), septal-PA, tricuspid-PA, and interatrial–electromechanical delay (IA-EMD), right intraatrial EMD, and left intraatrial (LI-EMD) durations in IBD patients (
P
< 0.001). In IBD patients, there was a positive correlation with age, lateral PA, septal PA, tricuspid PA, IA-EMD, and LI-EMD (
P
< 0.05). A positive correlation was found between disease duration and only lateral PA and tricuspid PA (
P
< 0.05).
Conclusion:
In IBD patients, prolonged ACT consists a potential risk for severe atrial arrhythmias. ECG and ECHO screening can be useful in identifying risk groups in IBD patients and taking precautions for future cardiac complications.

A novel technique using endoscopic band ligation for removal of long-stalked (>10 mm) pedunculated colon polyps: A prospective pilot study
p. 296
Hyun Ho Choi, Chang Whan Kim, Hyung-Keun Kim, Sang Woo Kim, Sok Won Han, Kyung Jin Seo, Hiun-Suk Chae
DOI
:10.4103/sjg.sjg_625_20
PMID
:33642356
Background:
Endoscopic removal of large and thick-stalked pedunculated colonic polyps, often leads to massive hemorrhage. Several techniques to minimize this complication have not been widely adopted due to some caveats. In order to prevent postpolypectomy bleeding, we invented a novel technique to dissect long-stalked pedunculated colonic polyps using endoscopic band ligation (EBL) by laterally approaching the stalk.
Methods:
In this prospective single-center study, 17 pedunculated polyps in 15 patients were removed between April 2012 and January 2016. We targeted pedunculated polyps with a long stalk length (>10 mm) and a large head (>10 mm) located in the distal colon. After identifying lesions with a colonoscope, we reapproached the middle part of the stalk of the targeted polyp with an EBL-equipped gastroscope to ligate it. Snare polypectomy was performed just above the ligation site of the stalk.
Results:
EBL-assisted polypectomy removed all of the lesions successfully, which were confirmed pathologically. There was little technical difficulty associated with the endoscopic procedures, regardless of polyp size and stalk thickness, except for one case with a very large polyp that impeded the visualization of the ligation site. We observed a positive correlation between procedure time and the diameter of the head (spearman ρ = 0.52,
P
= 0.034). After dissection of the polyp, the EBL bands remained fastened to the dissected stalks in all cases. There was no complication associated with polypectomy for 1 month.
Conclusion:
EBL-assisted polypectomy is an easy, safe, and effective technique to remove long-stalked pedunculated colonic polyps without postpolypectomy bleeding.

p. 302
Zhengqi Li, Lizhou Dou, Yong Liu, Yueming Zhang, Shun He, Jiqing Zhu, Yan Ke, Xudong Liu, Yumeng Liu, Hoiloi Ng, Guiqi Wang
DOI
:10.4103/sjg.sjg_646_20
PMID
:33642354
Background:
To observe and preliminarily evaluate the efficacy and safety of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) in the treatment of non-ampullary duodenal lesions (NADLs).
Methods:
This retrospective observational study included 84 patients who underwent endoscopic resection (ER) with non-ampullary duodenal lesions, between March 2010 and November 2020, at the Cancer Hospital of the Chinese Academy of Medical Sciences (Beijing, China). Data on patient demographics, therapeutic outcomes, and follow-up results were analyzed.
Results:
There were 44 patients undergoing EMR, and 40 patients accepting ESD. The overall en bloc resection rate was 98.8% (83/84). For the neoplastic lesions, the overall en bloc resection rate and curative rate were 98.5% (67/68) and 89.7% (61/68), respectively. The procedure-related bleeding and perforation rates were 2.4% and 10.7%, respectively. Univariate analysis results indicated that the main correlation factor of non-curative pathologic resection was tumor size (p = 0.004) and resection size (
P
< 0.01). There showed a higher curative rate in patients with tumors less than 25 mm in diameter. Multivariate logistic regression analyses determined that the tumor size (OR 0.935; 95% CI 0.878-0.995;
P
= 0.035) was associated with non-curative resection. No recurrences were observed in patients who had undergone a complete ER during a follow-up period of 42.8 months (range, 3-127 months).
Conclusion:
Endoscopic resection is an effective, safe, and feasible treatment for non-ampullary duodenal lesions.

Characteristics of patients who underwent gastric electrical stimulation vs. surgical pyloric interventions for refractory gastroparesis
p. 309
Saad Saleem, Azhar Hussain, Mohd A Alsamman, Faisal Inayat, Jasndeep Kaler, Aylin Tansel, Abell L Thomas
DOI
:10.4103/sjg.sjg_673_20
PMID
:34380871
Background:
There has been recent debate comparing the efficacy of gastric electrical stimulation (GES) with pyloric intervention, but medical literature lacks clear indications for when to perform GES or pyloric intervention. This study aims to assess the effect of sociodemographic factors and hospital characteristics on the surgical technique chosen for the treatment of gastroparesis.
Methods:
Data was extracted from the National Inpatient Sample between the years 2012 and 2014, using any discharge diagnosis of gastroparesis. For comparison of analysis between GES and pyloric surgical intervention, pyloroplasty, endoscopic pyloric dilation, and pyloromyotomy were considered to be pyloric interventions. The study population was divided into two groups, one which received GES and the other receiving pyloric intervention, to compare socioeconomic factors and hospital characteristics.
Results:
In total, 737,930 hospitalizations had a discharge diagnosis of gastroparesis between 2012 and 2014. On weighted multivariant analysis of patients undergoing GES or pyloric intervention for gastroparesis, being female (odds ratio (OR) 1.49, 95% confidence interval (CI) 1.25–1.78;
P
< 0.001), being Hispanic (OR 1.75, 95%CI;
P
< 0.001), being in urban teaching (OR 1.41, 95%CI 1.15–1.72;
P
< 0.001), and nonteaching hospitals (OR 2.93, 95%CI 2.4–3.58;
P
< 0.001), early satiety (OR 6.70, 95%CI 1.54–31.25;
P
= 0.01), and diabetes mellitus (OR 2.14, 95%CI 1.78–2.56;
P
< 0.001) were each statistically significantly correlated with receiving GES intervention compared to pyloric intervention.
Conclusion:
The racial difference, payer source, and hospital location affected the surgical intervention (GES or pyloric intervention) that patients with gastroparesis would receive.
