Abstract
BACKGROUND Prognostic stratification in ChronicPancreatitis(CP) remains suboptimal and cumbersome. Chronic Pancreatitis Prognostic Score(COPPS) was recently developed to predict one-year hospitalisations in CP. AIM External validation of COPPS in a geographically divergent patient population. METHODS A single-center prospective cohort study, conducted on out-patients of a tertiary-care hospital. Consecutive adults with CP were assessed for COPPS risk predictors at baseline, similar to the original development cohort, and followed for one-year for: 1)hospitalisations; 2)development of pancreatitis-related complications; and 3)need for endoscopic and/or surgical interventions. Outcomes were compared by Kendall's tau-b(τb) and other statistical tests. Only those who had complete one-year follow-up were included in analysis. RESULTS There were 177 patients(mean±SD age: 35.9 ± 11.2 years), 116(65%) males and 117(66%) with Idiopathic CP. Despite being younger, with significantly more females and Idiopathic CP, than the original development cohort, our cohort was similar to the latter regarding COPPS severity at baseline. Eight patients died over one-year; 169 were evaluated for outcomes. Increasingly severe COPPS categories correlated with increasing number of hospitalisations(both overall and pancreatitis-related) and increasing number of days spent in hospital(both overall and pancreatitis-related) irrespective of age at symptoms-onset(≤35 vs >35years), etiology(idiopathic vs alcohol) and smoking-status. CONCLUSIONS COPPS is effective in a geographically distinct cohort having a different case-mix of CP patients(ClincialTrials.gov ID:NCT04907266).

Abstract
AIM Chronic radiation proctitis (CRP) develops in 5-15% of patients after pelvic radiation therapy, with rectal bleeding being the main symptom. Reports suggest that argon plasma coagulation (APC) can be an effective therapy for CRP following radiotherapy for prostate cancer, but there is less information about how useful it is after radiotherapy for gynaecological malignancy. The aim of this work therefore was to study the efficacy of APC for CRP after radiotherapy for gynaecological malignancy. METHOD This was a prospective study of consecutive patients with CRP following radiotherapy for gynaecological malignancy at IPGME&R, SDLD, Kolkata, India; symptoms included rectal bleeding grade (RBG) ≥ 2. APC was performed at monthly intervals to a maximum of four treatment sessions. Severity of disease at baseline was graded (endoscopically) by the total colonoscopic severity score (TCSS) and treatment response was assessed by reduction in RBG from ≥ 2 to ≤ 1 measured at > 6 months after cessation of APC. RESULTS Seventy patients [90% with cervical cancer, 10% with endometrial cancer; mean age 51.93 ± 9.15 years; median RBG 3 (range 2-4)] received APC. Seven patients died due to underlying malignancy and seven patients were lost to follow-up. Fifty-six (85.7%) patients responded to therapy after a median of 2 (range 1-4) treatment sessions. Multivariate analysis demonstrated that a lower haemoglobin at the start of treatment predicted failure of therapy (P < 0.05). CONCLUSION APC is an effective management option for CRP in female patients with gynaecological malignancy. However, the more anaemic the patient the less likely it is to be successful.

Abstract
BACKGROUND Revisions in terminology of fluid collections in acute pancreatitis have necessitated reanalysis of their evolution and outcome. The course of fluid collections in patients with acute pancreatitis was evaluated prospectively. METHODS Consecutive adults with acute pancreatitis, who had contrast-enhanced CT (CECT) within 5-7 days of symptom onset, were enrolled in a prospective cohort study in a tertiary-care centre. Patients were treated according to standard guidelines. Follow-up transabdominal ultrasonography was done at 4-week intervals for at least 6 months. CECT was repeated at 6-10 weeks, or at any time if there were new or persistent symptoms. Asymptomatic collections were followed until spontaneous resolution. Risk factors for pancreatic pseudocysts or walled-off necrosis (WON) were assessed in multivariable analyses. RESULTS Of 122 patients with acute pancreatitis, 109 were analysed. Some 91 patients (83·5 per cent) had fluid collections at baseline. Eleven of 29 with interstitial oedematous pancreatitis had acute peripancreatic fluid collections, none of which evolved into pseudocysts. All 80 patients with acute necrotizing pancreatitis had at least one acute necrotizing collection (ANC); of these, five patients died (2 after drainage), three underwent successful drainage within 5 weeks, and collections resolved spontaneously in 33 and evolved into WON in 39. By 6 months' follow-up, WON had required drainage in eight patients, resolved spontaneously in 23 and was persistent but asymptomatic in seven. Factors associated with increased risk of WON were blood urea nitrogen 20 mg/dl or more (odds ratio (OR) 10·96, 95 per cent c.i. 2·57 to 46·73; P = 0·001) and baseline ANC diameter greater than 6 cm (OR 14·57, 1·60 to 132·35; P = 0·017). Baseline ANC diameter over 6 cm was the only independent predictor of either the need for drainage or persistence of such collections beyond 6 months (hazard ratio 6·61, 1·77 to 24·59; P = 0·005). CONCLUSION Pancreatic pseudocysts develop infrequently in oedematous acute pancreatitis. Only one-quarter of ANCs either require intervention or persist beyond 6 months, whereas more than one-half of WONs resolve without any intervention within 6 months of onset. Baseline diameter of ANC(s) is an important predictor of outcome.

Abstract
BACKGROUND AND AIMS Patient's posture change is commonly employed by a colonoscopist to achieve complete examination. We studied whether patient's posture (left-lateral decubitus vs supine) influenced the success rate of ileal intubation. PATIENTS AND METHODS In this prospective open-label randomized study performed in the Endoscopy Suite of a tertiary-care center, all adult outpatients referred for colonoscopy, in whom cecal intubation was achieved and who satisfied predefined inclusion criteria, were randomized to undergo ileal intubation in either of the above two postures. Colonoscopy (EC-201 WL, Fujinon) was performed after overnight poly-ethylene-glycol preparation, under conscious sedation and continuous pulse-oxymetry monitoring. After confirming cecal intubation, patients were randomized for ileal intubation. Success was defined by visualization of ileal mucosa or villi (confirmed by digital photography) and was attempted until limited by pain and/or time of ≥ 6 min. RESULTS Of 320 eligible patients, 217 patients (150 males) were randomized, 106 to left-lateral decubitus and 111 to supine posture. At baseline, the two groups were evenly matched. Successful ileal intubation was achieved in 145 (66.8 %) patients overall, significantly higher in the supine posture (74.8 % versus 58.5 %; P = 0.014). On multivariate analysis, supine posture (P = 0.02), average/good right-colon preparation (P < 0.01), non-thin-lipped ileocecal (IC) valve (P < 0.001) and younger age (P = 0.02) were independent predictors of success. Positive ileal findings were recorded in 13 (9 %) patients. CONCLUSION Ileoscopy is more successful in supine than in left-lateral decubitus posture. Age, bowel preparation and type of IC valve also determine success.

Abstract
BACKGROUND Topical glyceryl trinitrate (GTN) may produce healing of anal fissure by decreasing the high resting anal sphincter pressure in these patients. The present study assessed the efficacy of GTN in chronic anal fissure in a double-blind placebo-controlled trial. METHOD Patients with chronic anal fissure (for more than 8 weeks) underwent measurement of maximum anal resting pressure (MARP) before and 12 minutes after application of either 0.2% GTN or placebo ointment in a randomized manner. They then received twice-daily local application of their respective ointment for 6 weeks. Symptoms and healing of fissure were assessed; patients were evaluated at 3 months for evidence of relapse. RESULTS 19 adult patients (12 men) were studied; 10 received GTN and 9 placebo. Mean (SD) MARP decreased from 131.0 (32.3) cm H2O to 93.5 (28.4) cm H2O (p<0.05) with GTN and from 150.5 (36.9) cm H2O to 142.8 (35.0) cm H2O (p=ns) with placebo. Fissure healed in 7 of 10 patients treated with GTN and 2 of 9 patients treated with placebo (p<0.05). There was no relapse of fissure in either group. CONCLUSION Local application of GTN was effective in healing chronic anal fissure.

Abstract
BACKGROUND AND AIM Oxidative stress could play a role in the pathogenesis of antitubercular drug (ATD)-induced hepatotoxicity. We therefore studied the plasma level of reduced glutathione (GSH) and malondialdehyde (MDA) in patients with ATD-induced hepatotoxicity (cases), ATD-treated controls (disease controls) and in healthy volunteers. METHODS This study was carried out in a case-control design. Twenty-one cases, 21 age- and sex-matched disease controls, and 10 healthy volunteers were enrolled. Plasma levels of GSH and MDA were measured. RESULTS Plasma levels of GSH (median [range] 11.5 [6.2-21.2] mmol/dL) and MDA (1390 [560-2310] nmol/dL) of cases were significantly different (p<0.01) from GSH (18.4 [10.5-24.4]) and MDA (290 [240-550]) of disease controls. Further, plasma GSH and MDA levels of both the ATD-treated groups were different from those in healthy controls. CONCLUSION Lower levels of plasma GSH and higher levels of MDA may be due to oxidative stress resulting from ATD therapy.

Abstract
BACKGROUND The efficacy of anti-Helicobacter pylori treatment and cytoprotective drugs in H. pylori-positive and -negative non-ulcer dyspepsia (NUD), respectively, is debatable. METHODS In a randomized study, the efficacy of anti-H. pylori treatment versus sucralphate was tested in patients with NUD. One hundred and twelve patients with NUD, 62 positive and 50 negative for H. pylori were studied. Of 62 patients positive for H. pylori, 32 were treated with triple therapy (colloidal bismuth subcitrate, tetracycline and metronidazole) for 2 weeks and the remaining 30 were treated with sucralphate (1 g, q.i.d.) for 4 weeks. Of 50 patients negative for H. pylori, 25 each were treated with either sucralphate (1 g, q.i.d.) or ranitidine (150 mg, b.d.) for 4 weeks. RESULTS In patients with NUD and H. pylori infection, triple therapy eradicated H. pylori in 88% and was superior to sucralphate in producing symptom relief (81 vs 33%, P = 0.0003) and histological improvement in gastritis (73 vs 30%, P = 0.003). In the H. pylori-negative group, sucralphate was superior to ranitidine with regard to symptom relief (68 vs 36%, P = 0.04) and improvement in gastritis (44 vs 12%, P = 0.09). The symptomatic improvement persisted until 12 weeks after the start of treatment in triple therapy group only. CONCLUSIONS In patients with NUD associated with H. pylori, triple therapy was better than sucralphate in terms of symptomatic and histological improvement. However, sucralphate was superior to ranitidine in providing symptom relief in patients with H. pylori-negative NUD.

Abstract
Endoscopic procedures are difficult in patients with situs inversus owing to left-right reversal of viscera. Conventionally, reversal of the position of the endoscopist in relation to the patient is advocated to overcome the anatomical difficulty. We describe a patient with chronic calcific pancreatitis and pseudocyst of the pancreas who had situs inversus. ERCP was performed with minor modification of maneuvers with the patient in the usual left lateral decubitus and the endoscopist on the left of the table.

Abstract
Chronic diarrhea is a common clinical problem. To determine the possible causes in North India, we studied prospectively 71 patients with chronic diarrhea of the large bowel type. A definite diagnosis could be established in 70 patients. Ulcerative colitis was found in 18 patients, colorectal malignancies in three, colonic polyps in three, and irritable bowel syndrome in 32. In addition, seven patients with seronegative polyarthritis and chronic diarrhea were found to have chronic inflammation of the colon on histology. Two patients had pseudodiarrhea, and no diagnosis could be established in one patient. The remaining five patients with chronic diarrhea showed histologic evidence of chronic colonic inflammation with predominantly mononuclear cell infiltration of the lamina propria and increased intraepithelial lymphocytes, but results of their radiologic and endoscopic studies were normal. These five patients were classified as having microscopic (lymphocytic) colitis. We conclude that the causes of chronic diarrhea in North India patients are similar to a large extent to those seen in Western populations. Microscopic (lymphocytic) colitis is a definite clinicopathologic entity that should be considered in the differential diagnosis of chronic diarrhea.

Abstract
Fifty patients with idiopathic ulcerative colitis--25 with acute exacerbation of the disease (Group I) and 25 in quiescent phase (Group II)--were studied. None of the patients had a history of recent exposure to antimicrobial drugs or hospitalization. Evidence of infection with protozoal and bacterial agents and/or presence of Clostridium difficile toxin was demonstrated in eight (32%) patients in group I and one (4%) patient in group II (group I vs. group II, p < 0.05; chi 2 test with Yate's correction). In five of the six patients with demonstrable Clostridium difficile toxin in the stool, one patient with Entamoeba trophozoites, and another with Salmonella infection, the exacerbation responded clinically and endoscopically to specific antimicrobial therapy. Another two patients who had Entamoeba histolytica cysts in the stool had no change in their clinical status with metronidazole. We conclude that infectious agents are responsible for some of the exacerbations in patients of ulcerative colitis in a tropical country like India, where careful microbiologic examination is in order in every acute exacerbation of this disease. This contrasts with the findings in developed countries.
