RESUMO

BACKGROUND/AIMS: The national registry for inflammatory bowel disease (IBD) was designed to study epidemiology and prescribing pattern of treatment of IBD in India. METHODS: A multicenter, cross-sectional, prospective registry was established across four geographical zones of India. Adult patients with ulcerative colitis (UC) or Crohn's disease (CD) were enrolled between January 2014 and December 2015. Information related to demographics; disease features; complications; and treatment history were collected and analyzed. RESULTS: A total of 3,863 patients (mean age, 36.7 ± 13.6 years; 3,232 UC [83.7%] and 631 CD [16.3%]) were enrolled. The majority of patients with UC (n = 1,870, 57.9%) were from north, CD was more common in south (n = 348, 55.5%). The UC:CD ratio was 5.1:1. There was a male predominance (male:female = 1.6:1). The commonest presentation of UC was moderately severe (n = 1,939, 60%) and E2 disease (n = 1,895, 58.6%). Patients with CD most commonly presented with ileocolonic (n = 229, 36.3%) inflammatory (n = 504, 79.9%) disease. Extraintestinal manifestations were recorded among 13% and 20% of patients in UC and CD respectively. Less than 1% patients from both cohorts developed colon cancer (n = 26, 0.7%). The commonly used drugs were 5-aminosalicylates (99%) in both UC and CD followed by azathioprine (34.4%). Biologics were used in only 1.5% of patients; more commonly for UC in north and CD in south. CONCLUSIONS: The national IBD registry brings out diversities in the 4 geographical zones of India. This will help in aiding research on IBD and improving quality of patient care.

RESUMO

BACKGROUND: Paediatric inflammatory bowel disease (PIBD) is increasing across the world. However, information from India is sparse. This multicentre study evaluated the demographics, clinical phenotype and outcome of PIBD from India. METHODS: Data of children (≤18 years) with PIBD were collected using a proforma containing details of demographics, clinical profile, extraintestinal manifestations (EIM), investigations, disease extent and treatment. RESULTS: Three hundred twenty-five children [Crohn's disease: 65.2%, ulcerative colitis: 28.0%, IBD unclassified (IBDU): 6.7%, median age at diagnosis: 11 (interquartile range 6.3) years] were enrolled. 6.9% children had family history of IBD. Pancolitis (E4) was predominant in ulcerative colitis (57.8%) and ileocolonic (L3, 55.7%) in Crohn's disease. Perianal disease was present in 10.9% and growth failure in 20.9% of Crohn's disease cases. Steroids were the initial therapy in 84.2%, 5-amino salicylic acid in 67.3% and exclusive enteral nutrition (EEN) in 1.3% cases. Overall, immunomodulators and biologics were given to 84.3 and 17.9% cases, respectively, and 2.9% cases underwent surgery. Very early onset IBD (VEOIBD) was seen in 60 (19.2%) children. IBDU was commoner in the VEOIBD than the older-PIBD (18/60 vs 4/253; P < 0.001). VEOIBD-Crohn's disease patients more often had isolated colonic disease than the older Crohn's disease (45.4% vs 11.8%; P < 0.001). Prevalence of perianal disease, EIM, therapeutic requirements and outcome were not different between VEOIBD and older-PIBD. CONCLUSION: Disease location and phenotype of PIBD in Indian children is similar to the children from the west. However, the therapeutic options of EEN, biologics and surgery are underutilized. VEOIBD accounted for 19.2% of PIBD.

RESUMO

Coronavirus disease 2019 (COVID-19), which started in December 2019 in China, has resulted in a pandemic leading to significant morbidity and mortality across the globe. Although it mainly causes respiratory symptoms, respiratory failure and death due to multiorgan failure, there is evolving evidence to suggest gastrointestinal (GI) and liver involvement by this virus. Owing to this, health-care professionals taking care of GI and liver diseases are also at an increased risk of getting exposed. Hence, there is a need for protocols to be prepared to guide the handling of COVID-19 patients by the GI and liver specialists, as well as to manage the pre-existing GI and liver diseases during the ongoing pandemic. We present here the guidelines prepared jointly by the three Indian professional bodies in the field of GI diseases, namely the Society of Gastrointestinal Endoscopy of India, Indian Society of Gastroenterology, and Indian National Association for the Study of the Liver.

RESUMO

Neuroendocrine tumors (NET) are rare neoplasms and commonly metastasize to liver, lymph nodes and less frequently to bones and lungs. Metastases to other organs are extremely rare and we report a case of NET clinically presenting with bilateral proptosis secondary to metastases in orbits. Ga-DOTANOC PET/CT demonstrated somatostatin receptor overexpressing lesions in bilateral orbits, small intestine, lymph nodes, lungs, heart and testes in the absence of liver metastases.

RESUMO

Gastrointestinal endoscopies can cause an unpleasant experience for the patient. In India, most endoscopists follow a common institutional policy for sedation. The aim of this study was to analyze the sedation practices in various endoscopy centers across southern India. Data were collected with the help of a structured questionnaire given to a senior endoscopist of the center. Data from the completed questionnaire were later analyzed. Data were obtained from 19 centers across southern India. All endoscopy suites had central oxygen supply and emergency cart. A defibrillator was available in 12 centers (63.2%). Common criteria followed for administering sedation included therapeutic procedures (84.2%), patients who requested sedation (63.2%), children (63.2%), high-risk procedures (57.9%), and uncooperative patients (57.9%). Monitoring methods included pulse oximetry alone in six centers (31.6%), pulse oximetry with blood pressure monitoring in five centers (26.3%), and pulse oximetry, blood pressure, and electrocardiography (ECG) monitoring in eight centers (42.1%). For advanced procedures like endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP), sedation was universally used. An anesthesiologist was available in the endoscopy suite in eight centers (42.1%). Five endoscopists administered propofol sedation without anesthesiologist's presence (26.3%). Thirteen centers had a written protocol for pre-procedure risk assessment (68.4%). A dedicated post-procedure observation area was available in seventeen centers (89.5%). Seven centers followed a written post-sedation discharge protocol (36.8%). Significant variations exist in the practice of sedation among endoscopists in southern India. There is an urgent need to formulate guidelines by endoscopy societies for ensuring better patient outcomes in endoscopy.

RESUMO

Achalasia cardia (AC) is a frequently encountered motility disorder of the esophagus resulting from an irreversible degeneration of neurons. Treatment modalities are palliative in nature, and there is no curative treatment available for AC as of now. Significant advancements have been made in the management of AC over last decade. The introduction of high resolution manometry and per-oral endoscopic myotomy (POEM) has strengthened the diagnostic and therapeutic armamentarium of AC. High resolution manometry allows for the characterization of the type of achalasia, which in turn has important therapeutic implications. The endoscopic management of AC has been reinforced with the introduction of POEM that has been found to be highly effective and safe in palliating the symptoms in short-term to mid-term follow-up studies. POEM is less invasive than Heller's myotomy and provides the endoscopist with the opportunity of adjusting the length and orientation of esophageal myotomy according to the type of AC. The management of achalasia needs to be tailored for each patient, and the role of pneumatic balloon dilatation, POEM, or Heller's myotomy needs to be revisited. In this review, we discuss the important aspects of diagnosis as well as management of AC. The statements presented in the manuscript reflect the cumulative efforts of an expert consensus group.

RESUMO

BACKGROUND: Inflammatory bowel disease (IBD) is considered uncommon in Asia. The aim of this study was to document the demographic characteristics and clinical aspects of ulcerative colitis (UC) and Crohn's disease (CD) in Kerala, India. METHODS: A survey of IBD in Kerala was performed. All gastroenterologists in the region were invited. From May 2013 to October 2015, data were collected in a standardized pro-forma. RESULTS: Forty-seven doctors in 34 centers contributed data. A total of 2142 patients were analyzed. This is the largest state-wide survey of IBD in India. Ulcerative colitis was diagnosed in 1112 (38 new), Crohn's disease in 980 (53 new), and 50 were unclassified (5 new). The district-wise distribution of IBD cases correlated with the District-wise Gross State Domestic Product (r = 0.69, p < 0.01). Three percent was below the age of 18. Patients with UC had more diarrhea (73% vs. 51%), bleeding PR (79% vs. 34%), and intermittent flares (35% vs. 13%) (all p < 0.01). Patients with CD had more abdominal pain (62% vs. 46%), weight loss (53% vs. 40%), fever (28% vs. 18%), and history of antituberculosis treatment (21% vs. 5%) (all p < 0.01). Compared to adults, children (below 18 years) were more likely to have extensive UC (58% vs. 34%, p < 0.01) and unclassified IBD (15% vs. 2%, p < 0.01). CONCLUSION: Inflammatory bowel disease is common in Kerala, India. The disease characteristics of patients with IBD are almost similar to those from other parts of the country. Both UC and CD were seen in equal proportion in Kerala.

RESUMO

Delays between tissue collection and tissue fixation result in ischemia and ischemia-associated changes in protein phosphorylation levels, which can misguide the examination of signaling pathway status. To identify a biomarker that serves as a reliable indicator of ischemic changes that tumor tissues undergo, we subjected harvested xenograft tumors to room temperature for 0, 2, 10 and 30 minutes before freezing in liquid nitrogen. Multiplex TMT-labeling was conducted to achieve precise quantitation, followed by TiO2 phosphopeptide enrichment and high resolution mass spectrometry profiling. LC-MS/MS analyses revealed phosphorylation level changes of a number of phosphosites in the ischemic samples. The phosphorylation of one of these sites, S82 of the heat shock protein 27 kDa (HSP27), was especially abundant and consistently upregulated in tissues with delays in freezing as short as 2 minutes. In order to eliminate effects of ischemia, we employed a novel cryogenic biopsy device which begins freezing tissues in situ before they are excised. Using this device, we showed that the upregulation of phosphorylation of S82 on HSP27 was abrogated. We thus demonstrate that our cryogenic biopsy device can eliminate ischemia-induced phosphoproteome alterations, and measurements of S82 on HSP27 can be used as a robust marker of ischemia in tissues.

RESUMO

In 2012, the Indian Society of Gastroenterology's Task Force on Inflammatory Bowel Diseases undertook an exercise to produce consensus statements on Crohn's disease (CD). This consensus, produced through a modified Delphi process, reflects our current recommendations for the diagnosis and management of CD in India. The consensus statements are intended to serve as a reference point for teaching, clinical practice, and research in India.

RESUMO

Magnetic Resonance Imaging (MRI) provides superior soft-tissue contrast in cancer diagnosis compared to other imaging modalities. However, the strong magnetic field inside the MRI bore along with limited scanner bore size poses significant challenges. Since current approaches in breast biopsy using MR images is primarily a blind targeting approach, it is necessary to develop a MRI-compatible robot that can avoid multiple needle insertions into the breast tissue. This MRI-compatible robotic system could potentially lead to improvement in the targeting accuracy and reduce sampling errors. A master-slave surgical system has been developed comprising of a MRI-compatible slave robot which consists of one piezo motor and five pneumatic cylinders connected by long pneumatic transmission lines. The slave robot follows the configuration of the master robot, which provides an intuitive manipulation interface for the physician and operates inside the MRI bore to adjust the needle position and orientation and perform needle insertion task. Based on the MRI experiments using the slave robot, there was no significant distortion in the images and hence the slave robot can be safely operated inside the MRI with minimal loss in signal-to-noise ratio (SNR). Ex vivo and in vivo experiments have been conducted to evaluate the performance of the master-slave surgical system.

RESUMO

INTRODUCTION: Service sector in Indian industrial growth has obtained significant numbers. Automobile service industry is one of the largest in the world with a majority of the workers in unorganized sector of the industry. This study was carried out among auto service industry workers in Vellore urban area to assess possible occupation related morbidity. MATERIALS AND METHODS: A cross-sectional observation study was carried out among 106 automobile repair shop workers. RESULTS: Half (47%) suffered work related stress, 32 (30.2%) reported exposure to dust, 81 (76%) to heat, and 50 (17%) to hazardous chemicals and heavy metals. More than 90% reported over exposure to petroleum products. A third reported cough for more than 2 weeks, more than a quarter reported gastrointestinal symptoms associated with work. Half of them reported musculoskeletal complaints associated with work with a quarter reporting un-intentional work place injuries. A tenth of them were found to have reduced pulmonary function on testing and nearly half had impaired sensory functions in peripheries. Reduced pulmonary function was found to be significantly associated with heavy metal exposure (P = 0.001). Peripheral neuropathy was significantly associated with years of occupation (P = 0.001), exposure to petroleum products (P = 0.03) and exposure to heavy metals (P = 0.018). DISCUSSION: Half of the workers were unaware of health problems associated with their occupational exposures and thereby the use of personal protection is abysmally low. A very high proportion of workers had symptoms of cough, breathlessness, abdominal pain, abdominal discomfort and muscle aches. Almost a quarter of the workers had un-intentional occupational injuries in the last 6 months. Though they work in a high-risk environment with chances of fire hazard, falls and chemical exposures, none of the workshops had fire-extinguishers, first aid kits or any such safety devices.

RESUMO

Von Recklinghausen's disease or type 1 neurofibromatosis is an autosomal dominant disease characterized by mucocutaneous neurofibromas, café-au-lait spots and involves many organs including gastrointestinal tract. Gastrointestinal involvement in neurofibromatosis is uncommon and is seen 25% patients and nearly 5% of them are only symptomatic (Shekitka and Sobin, Am J Surg Pathol 18:250-257, 1994; Tomita et al., Int J Colorectal Dis 21: 89-91, 2006).

RESUMO

BACKGROUND: Current laparoscopic images are rich in surface detail but lack information on deeper structures. This report presents a novel method for highlighting these structures during laparoscopic surgery using continuous multislice computed tomography (CT). This has resulted in a more accurate augmented reality (AR) approach, termed "live AR," which merges three-dimensional (3D) anatomy from live low-dose intraoperative CT with live images from the laparoscope. METHODS: A series of procedures with swine was conducted in a CT room with a fully equipped laparoscopic surgical suite. A 64-slice CT scanner was used to image the surgical field approximately once per second. The procedures began with a contrast-enhanced, diagnostic-quality CT scan (initial CT) of the liver followed by continuous intraoperative CT and laparoscopic imaging with an optically tracked laparoscope. Intraoperative anatomic changes included user-applied deformations and those from breathing. Through deformable image registration, an intermediate image processing step, the initial CT was warped to align spatially with the low-dose intraoperative CT scans. The registered initial CT then was rendered and merged with laparoscopic images to create live AR. RESULTS: Superior compensation for soft tissue deformations using the described method led to more accurate spatial registration between laparoscopic and rendered CT images with live AR than with conventional AR. Moreover, substitution of low-dose CT with registered initial CT helped with continuous visualization of the vasculature and offered the potential of at least an eightfold reduction in intraoperative X-ray dose. CONCLUSIONS: The authors proposed and developed live AR, a new surgical visualization approach that merges rich surface detail from a laparoscope with instantaneous 3D anatomy from continuous CT scanning of the surgical field. Through innovative use of deformable image registration, they also demonstrated the feasibility of continuous visualization of the vasculature and considerable X-ray dose reduction. This study provides motivation for further investigation and development of live AR.

RESUMO

Laparoscopic approach for treatment of colorectal malignancy is gaining acceptance gradually; however the benefits of laparoscopic surgery in colonic and rectal tumours is still open to debate. This study aims at a retrospective analysis of operative and short term outcome of patients with rectosigmoid tumours. A retrospective analysis of operative, postoperative and short-term outcome of 62 patients who underwent laparoscopic colorectal resection for cancer of rectosigmoid region were compared with a same number of parameters-matched patients who underwent open colorectal resection. Blood transfusion requirement was significantly more in the open group compared to the laparoscopy group (38.7% versus 6.4%, p = 0.001). ICU stay was less in the laparoscopy group (p = <0.05) and they were started on oral liquid diet earlier (p = 0.013). The number of the lymph nodes retrieved, positive distal margin and radial involvement were similar in both groups. The hospital stay was significantly shorter in laparoscopy group (8.4 versus 13.8 days, p < 0.05). Radical operation for rectosigmoid tumors is technically feasible with laparoscopic surgery. Laparoscopic approach is associated with less blood loss, transfusion and significantly less ICU stay. Laparoscopic group recovers early and needs less hospital stay.
