ABSTRACT
BACKGROUND: Endoscopic sub-mucosal dissection (ESD) is an established endoscopic modality for the management of colorectal polyps. However, there are no studies regarding the outcomes of ESD from India. In this study, we aimed at evaluating the outcomes of ESD in patients with adenomatous polyps in the colon and rectum. METHODS: Data of consecutive patients who underwent ESD for colorectal polyps from 2018 to 2021 were analyzed, retrospectively. The primary outcome of the study was the technical success of ESD. The secondary outcomes included the rate of histologically complete resection (R0), adverse events and recurrence. RESULTS: Seventy patients (63.5 years, 60% males) underwent ESD for polyps in colon and rectum. A majority were located in rectum (80%) and sigmoid colon (15.7%). Narrow band classification of the polyps was Japanese Narrow Band Imaging Expert Team (JNET)-2a in 50 (71.4%) and JNET-2b in 13 (18.6%) patients. ESD was technically successful in 64 (91.4%) patients using conventional technique (72.8%) and pocket or tunnelling technique (18.6%). There were no major adverse events. Histologically RO was achieved in 58 (82.8%) patients and deep sub-mucosal invasion was noted in 12 patients. At a median follow-up of 19 (interquartile range [IQR] 15-27) months, recurrence was noticed in four (5.7%) patients all of which could be managed endoscopically. CONCLUSION: ESD, performed at a tertiary care centre in India, yields high rates of technical success and histologically R0, with a relatively low incidence of adverse events and recurrences.
ABSTRACT
BACKGROUND AND AIM: Achalasia cardia, a primary motility disorder of the esophagus, poses significant malnutrition risks. This study aims at comprehensively assessing the nutritional status in untreated achalasia patients, contrasting it with functional gastrointestinal disorders (FGIDs) cases and impact of per-oral endoscopic myotomy (POEM) on nutrition at one-year. METHODS: We conducted a prospective study, including consecutive achalasia cases, from December 2021 to April 2022 at a tertiary care centre. Biochemical parameters, anthropometry, subjective global assessment (SGA) and malnutrition universal screening tool were used for nutritional assessment. Cases diagnosed with FGIDs served as controls. RESULTS: As many as 118 cases (41.2 ± 13.9 years, 61% males) with achalasia and 200 controls (43.4 ± 11.9 years, 69% males) were included in the study. Sub-types of achalasia included type I (16.9%), II (76.3%) and III (6.8%). Overall, 38.1% and 6.8% cases were moderately and severely malnourished, respectively. As compared to controls, cases with achalasia had lower pre-albumin (19.4 vs. 25.2; p = 0.001), serum calcium (p = 0.012), vitamin D (p = 0.001), serum iron (p = 0.001), triceps fold thickness (p = 0.002) and hand-grip strength (p = 0.001). On univariate analysis, type-I achalasia, body mass index, % weight loss, lower esophageal sphincter pressures and Eckardt scores were predictors of malnourishment (SGA). On multivariate analysis, type of achalasia, mid arm circumference and low body mass index were significant predictors of malnourishment in cases with achalasia. There was significant improvement in the nutritional status after POEM at one-year follow-up. CONCLUSION: Achalasia patients demonstrate a notably higher risk of malnutrition compared to individuals with FGIDs. Nutritional status significantly improves after POEM. (NCT05161923).
