Advanced fibrosis and cirrhosis (compensated advanced chronic liver disease [cACLD]) are clinically indistinguishable and increase risk of developing clinically significant portal hypertension. Baveno VII recommends using elastography to rule out and diagnose cACLD with liver stiffness measurement (LSM) cut-offs of 10/15 kPa.In a retrospective analysis of 330 nonalcoholic fatty liver disease (NAFLD) patients, performance of the Baveno VII cut-offs for diagnosing cACLD was compared with newly suggested lower cut-offs (8/12 kPa). A model for detecting cACLD among those with LSM between 8 and 12 kPa was developed and compared with recently published models.Seventy (21.2%) of the 330 NAFLD patients had biopsy-proven cACLD. The Baveno VII cut-offs (10/15 kPa) had a lower sensitivity of 72.8% (60.9-82.8%) and a specificity of 93.4% (89.7-96.1%). Sensitivity and specificity of lower cut-offs (8/12 kPa) were 91.4% (82.3-96.8%) and 88.5% (83.9-92.1%), respectively. Modeling based on the presence of diabetes (odds ratio [OR] 3.625[1.161-11.320], p = 0.027) and serum aspartate aminotransferase (AST) levels (OR 1.636[1.098-2.436], p = 0.015) correctly identified 75.7% of patients with LSM between 8 and 12 kPa. Our model performed best with an area under receiver operator curve (AUROC) of 0.725 (95%CI 0.609-0.822), compared to Papatheodoridi (AUROC 0.626, CI 0.506-.736) and Zhou (AUROC 0.523, CI 0.403-0.640) models. A two-step strategy comprising application of lower LSM cut-offs followed by the predictive model correctly identified the presence of cACLD in 83% of the patients as compared to 75% by the Baveno VII cut-offs.A two-step strategy employing lower LSM cut-offs and modeling based on diabetes and AST levels outperforms Baveno VII cut-offs for identifying cACLD in NAFLD patients.

Optimal outcomes in acute severe ulcerative colitis (ASUC) are related to time-bound management based upon early prediction of response to intravenous (IV) steroids. In an earlier study, we described the All India Institute of Medical Sciences (AIIMS) index (baseline Ulcerative Colitis Endoscopic Index of Severity [UCEIS] ≥ 7 and day 3 fecal calprotectin [FCP] 1000 μg/g) for predicting failure of IV steroids. The current study is designed to validate this index in a prospective cohort.IV steroid-naïve patients with ASUC, satisfying Truelove and Witts' criteria, hospitalized from August 2018 to July 2019 were included. Patients' assessment included baseline sigmoidoscopy, day 1 and 3 FCP, hemogram, biochemistry and day 3 C-reactive protein. All patients received IV steroids, and the primary outcome was steroid failure, defined as the need for colectomy or rescue therapy with cyclosporine (CYC)/infliximab (IFX) during admission.Of the 47 patients, eight were excluded (four received steroids outside, two were directly taken for surgery/infliximab therapy, one had toxic megacolon, and one had infectious colitis), and 39 patients were included (mean age: 36.1 ± 12.6 years, male: 31%). Fifteen patients (38%) failed IV steroid and required rescue therapy (IFX: 9, CYC: 2, Colectomy: 3, IFX followed by colectomy: 1). On univariate analysis, UCEIS ≥ 7 at baseline (p = 0.006), day 1 FCP (p = 0.03), day 3 FCP 1000 μg/g (p = 0.001), Oxford criteria (p = 0.04) and AIIMS index (p 0.001) were significantly different between steroid responders and steroid failures. On multivariate analysis, day 3 FCP 1000 μg/g (odds ratio (odds ratio (OR)= 6.4;(95% CI =2.2-196.1) and baseline UCEIS ≥ 7 (OR) = 10.1;(95% CI = 2.1-80.2) were independent predictors. The AIIMS index predicted steroid failure with a better specificity (100% vs. 83%, p = 0.04) and positive predictive value (100% vs. 64%, p = 0.03) than Oxford criteria.AIIMS index has been validated in 39 prospective ASUC patients as an effective early predictor of steroid failure (sensitivity = 53%, specificity = 100%).

Background/Aims: Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn’s disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India.Methods: This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn’s Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response.Results: Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2–6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260–320] vs. 240 [180–280], P= 0.001) and 8 weeks (baseline 290 [260–320] vs. 186 [160–240], P= 0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P= 0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P= 0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002–1.017; P= 0.046) predicted response to EEN.Conclusions: EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.

Sarcopenia and visceral fat independently predict poor outcomes in Crohn's disease (CD). However, combined influence of these parameters on outcomes is unknown, and was investigated in the present study.This retrospective study evaluated skeletal muscle index (SMI-cross-sectional area of five skeletal muscles normalized for height), visceral and subcutaneous fat area and their ratio (VF/SC) on single-slice computed tomography (CT) images at L3 vertebrae in CD patients (CT done: January 2012-December 2015, patients followed till December 2019). Sarcopenia was defined as SMI 36.5 cmForty-four patients [age at onset: 34.4 ± 14.1 years, median disease duration: 48 (24-95) months, follow-up duration: 32 (12-53.5) months, males: 63.6%] were included. Prevalence of sarcopenia was 43%, more in females, but independent of age, disease severity, behavior and location. More patients with sarcopenia underwent surgery (31.6% vs 4%, p = 0.01). VF/SC was significantly higher in patients who underwent surgery (1.76 + 1.31 vs 0.9 + 0.41, p = 0.002), and a cutoff of 0.88 could predict surgery with sensitivity and specificity of 71% and 65% respectively. On survival analysis, probability of remaining free of surgery was lower in patients with sarcopenia (59.6% vs 94.1% p = 0.01) and those with VF/SC 0.88 (66.1% vs 91.1%, p = 0.1), and still lower in those with both sarcopenia and VF/SC 0.88 than those with either or none (38% vs 82% vs 100%, p = 0.01).Combination of sarcopenia and high visceral fat predict worse outcomes in CD than either.

The decision to withdraw anti-tumor necrosis factor (anti-TNF) therapy in patients with inflammatory bowel disease (IBD) remains controversial, especially in the developing world, where its long-term use is restrained by side effects and prohibitive cost. Present study evaluated the relapse rate and its predictors following anti-TNF withdrawal in a cohort of IBD patients from northern India. Patients with IBD who received anti-TNF therapy (induction and beyond), and were under follow-up at All India Institute of Medical Sciences, New Delhi, from January 2005 to July 2018 were included. Demographic features, disease characteristics, duration, response to anti-TNF therapy, and relapse rate after its withdrawal were analyzed. Among 4600 patients with IBD under follow-up, 90 (1.9%) received anti-TNF therapy, of whom 11 were excluded (8—complete records unavailable; 3—received only single dose). Of 79 patients (mean age—40.1 ± 14.2 years; 53.2% males; 31 [39.2%] ulcerative colitis, 47 [59.5%] Crohn’s disease; median follow-up—24 [12–39] months), 9 (11.4%) were primary non-responders, 19 (24.1%) had secondary loss of response, and 51 (64.5%) maintained clinical response on anti-TNF. Anti-TNF was withdrawn in 45 (57%) patients (major causes: financial burden—16.5%; tubercular reactivation—12.7%), of whom 33 were in clinical remission. Over a median follow-up of 26 (7.5–45) months, 15 patients (45.5%) relapsed. Most of them responded to antibiotics, steroids, or anti-TNF agents; only 3 required surgery. On Kaplan-Meier analysis, long disease duration prior to therapy was a significant predictor of relapse (hazard ratio [HR] = 1.33, p = 0.034). Almost 50% patients with IBD in clinical remission relapse within a year of anti-TNF withdrawal. However, most of these patients have a favorable disease course and respond to medical therapy.

An accidentally retained sponge inside the body of a patient (gossypiboma) is a rare and serious adverse event after a surgical procedure with serious medicolegal implications and complications. It is commonly associated with abdominal surgeries with cholecystectomy most commonly implicated. Whorl-like appearance or mottled translucencies and radiopaque marker on imaging is diagnostic. Transmural migration into a hollow viscous has been infrequently reported. The preferred approach for the removal of gossypiboma is surgery. However, in cases of complete transmural migration, endoscopic removal remains a viable option.

Cholecystectomy is one of the commonest general surgical procedures performed all over India. The risk of bile duct injury (BDI) during laparoscopic cholecystectomy is two to three times higher than during open cholecystectomy. The worldwide incidence of bile duct injury is 0.5% or 1 in 200 cases. BDI and its consequences result in significant morbidity and may even cause mortality. BDI increases the cost of treatment and is a common reason for a medicolegal suit against the surgeons. To minimize the incidence of BDI and to manage it timely and appropriately, a set of guidelines was deemed necessary by a group of senior surgeons during a Society of Endoscopic and Laparoscopic Surgeons of India (SELSI) meeting in 2016. Guidelines for “Safe Laparoscopic Cholecystectomy” and bile duct injury management formulated by other international societies are already available. The applicability of these guidelines to Indian subjects especially in small peripheral centers was limited. Hence, a decision was taken to form a set of guidelines for general surgeons with basic laparoscopic skills with little or no advanced laparoscopic skills. Those working in a solo practice, nursing homes, and small private hospitals at talukas or districts should have “Safe Cholecystectomy” guidelines and management of BDI suitable to their situation. These guidelines were formed after three consensus meetings and have been approved by a SELSI Expert Group.

The aim of the study was to find out the carbapenem resistance rate and prevalence of different carbapenemase genes in Klebsiella pneumoniae and Escherichia coli from a North Indian corporate hospital that receives both Indian and international patients. A total of 528 clinical isolates of E. coli and K. pneumoniae were included in the study. All isolates that were found resistant to carbapenems by MIC testing (Vitek II Compact®) were screened for NDM, OXA-48, VIM, and KPC genes by PCR. Sequencing of NDM gene and transmissibility by conjugation assay were checked on 22 randomly selected NDM-positive isolates. One hundred and fifty-six isolates (29.54%) were carbapenem-resistant. The rate of carbapenem resistance was significantly higher in K. pneumoniae as compared to E. coli (53.9% vs. 15.6%; p E. coli than K. pneumoniae (p . All the tested isolates formed transconjugants and NDM-5 was the most common variant in both species (15/22). The presence of plasmid-based NDM calls for stricter surveillance measures in our hospital settings.

Colistin resistance in Gram negative bacteria is mainly attributed to chromosomal mutations in Two Component Systems(TCS) PhoPQ and PmrAB and plasmid-borne genes(mcr and its variants). The aim of this study was to understand the molecular basis of colistin resistance in Klebsiella pneumoniae and determine clonal transmission, in a North Indian tertiary care hospital over a 2.5 year period. Antimicrobial susceptibility was determined by Vitek and colistin resistance was confirmed by broth microdilution. Carbapenemases(blaKPC, blaVIM, blaIMP, blaNDM, blaOXA-48) and mcr-1 screening was done by PCR. Mutations in chromosomal genes mgrB, phoP, phoQ, pmrA, pmrB were analysed. Sequence typing was performed by Multilocus sequence typing(MLST). OXA-48 was detected in thirteen isolates while three isolates co-expressed OXA-48 and NDM. The mcr-1 gene was absent in all 16 isolates. Deleterious mutations in mgrB included insertion sequences IS903 and ISkpn26 and a premature stop codon. A total of 18 point mutations were identified in PhoPQ and PmrAB TCS; of which, novel mutations were reported in phoQ (K46E, L322V, D152N, F373L, R249G), pmrB (P159R) and pmrA (D149L). Six different sequence types ST231, ST147, ST395, ST42, ST14 and ST101 were identified. Phylogenetic analysis showed that sequence types ST14, ST395 and ST147 are closely related to ST101 and all identified sequence types had a common ancestor ST231. Colistin resistance in K. pneumoniae was attributed to mutations in PhoPQ and PmrAB TCS, while location specific distribution of strains indicates clonal transmission. The results of this study will help in formulation of effective infection prevention and antimicrobial development strategies.

Crohn’s disease (CD) is often complicated by strictures and associated with increased risk for surgery. Inflammatory strictures respond to medical therapy, and anti-tumor necrosis factor (TNF) therapy is often used after the failure of steroids. However, data on efficacy of anti-TNF therapy in stricturing CD is limited. We retrospectively analysed the records of patients with stricturing CD who were treated with anti-TNF therapy and were prospectively followed from January 2005 to July 2020. Treatment success was defined as continuation of anti-TNF without the requirement for steroids or parenteral nutrition, switch to other anti-TNF, endoscopic dilation, surgery and severe adverse events leading to the withdrawal of anti-TNF. Fifty-nine patients were included [50-infliximab, 9-adalimumab; mean age-30.1 ± 15 years; males-69.5%; median disease duration-124 (range 30–396) months; median follow-up duration-42 (range 8–180) months]. Ileum was the most common site of stricture (69.5%), 20.3% of patients had colonic strictures, and 64.4% had multiple strictures. 55.9% of patients were steroid dependent and 37.3% were steroid refractory. The median duration of anti-TNF therapy was 14 (range 2–96) months, and 54.2% (n = 32) patients received concomitant immunomodulators. 88% improved with induction (11.8% primary non-response), secondary loss of response was seen in 52.2%, and the cumulative probability of treatment success at 1, 2 and 5 years was 69%, 51%, and 28% respectively. Anaemia at presentation predicted poor response. Only 30% of patients retained biologics on long-term (lack of response, cost, adverse events). 16.9% had adverse events, the commonest being reactivation of tuberculosis (5.1%). Anti-TNF therapy is associated with good short-term treatment success with modest long-term response in stricturing CD.

BACKGROUND Intravenous corticosteroids are the mainstay of therapy for acute severe ulcerative colitis (ASUC), but 30%-40% of patients fail to respond. AIM To investigate the effectiveness of exclusive enteral nutrition (EEN) as adjunctive therapy to intravenous corticosteroids in patients with ASUC. METHODS This was an open-label randomised controlled trial, in which patients who were admitted with ASUC between August 2018 and May 2020 were randomised 1:1 to EEN or standard of care (SOC). Patients on EEN received a semi-elemental formula for 7 days along with SOC. The primary outcome was corticosteroid failure, defined by the need for salvage medical therapy or colectomy. Faecal microbial analysis was performed on day 1 and day 7 by 16s ribosomal RNA sequencing in some patients. RESULTS Of 62 patients (mean age 35.3 ± 12.1 years, 40% male), 32 were randomised to EEN and 30 to SOC. Corticosteroid failure was lower on EEN compared to SOC (intention-to-treat analysis 25% vs 43%, P = 0.051; per protocol analysis 19% vs 43%, P = 0.04), without any difference in colectomy rate (9% vs 13%; P = 0.41). Patients on EEN had a shorter hospital stay [median (range) 10 (8-17) vs 13 (8-24) days; P = 0.04], higher day 7 albumin level (34 ± 4 vs 29 ± 3 g/L, P

Assigning a numerical value to post-operative morbidity may improve its usefulness as an outcome measure. The recently developed Comprehensive Complication Index (CCI) is a step forward in this process but assigns an inappropriately high score to a combination of complications. We developed a new score called the complication severity score (CSS) using a mathematical process and compared it with the CCI using a questionnaire-based survey of 49 experienced gastrointestinal and hepato-pancreatico-biliary surgeons. The CSS was modified based on the results of this survey and was correlated with other patient-centered outcomes in a prospective cohort of consecutive patients undergoing elective surgery. Of the nine sets of scenarios, experienced surgeons’ opinion matched with CSS in 6, CSS as well as CCI in 1, and neither CSS nor CCI in 2 scenarios. Of the total 441 responses, 281 matched with CSS while 143 matched with CCI (p = 0.0001, odds ratio: 3.7; 95% CI: 2.8 to 4.8). The modified CSS significantly correlated with the post-operative length of stay (r = 0.76; 95% CI: 0.68 to 0.82; p

Background Opioid-sparing analgesia for bariatric surgery in morbidly obese can potentially prevent catastrophic airway complications. Our meta-analysis attempts to consolidate the evidence on dexmedetomidine evaluating its analgesic and safety profile. Methods Trails comparing perioperative dexmedetomidine infusion to conventional analgesic regimens for bariatric surgery were searched. Comparisons were made for 24-hour and postanesthesia care unit (PACU) morphine consumed, PACU pain scores, postoperative nausea and vomiting pain scores, and heartrate. Meta-regression was performed for length of stay to evaluate various analgesic control subgroups. Results Six trials were included in the final analysis. Dexmedetomidine infusion (reported in 5 intraoperative subgroups and 2 postoperative subgroups) decreased 24-hour morphine by 18.13±6.11 mg (random effects: P 2 = 95.48%). Despite the small number of included studies, the sample size for avoiding a false positive result was adequate as the trial sequential analysis found the present sample size (362) to be well past the required "sample size" (n = 312) for 85% power. Meta-regression for infusion dose on morphine consumption difference found a predictability of 49% (coefficient = 39.93, random-effects, Tau 2 = 396.08), and predictability of the model improved to 68% on inclusion of time of initiation of infusion. The dexmedetomidine group had lower PACU morphine consumption (by 6.91±1.19, I 2 = 34.37%), lower pain scores (scale of 0–10±2.27, I 2 = 88.14%), lower postoperative nausea and vomiting incidence (odds ratio=±0.26, I 2 = 0%), and lower heart rate (73.25 versus. 83.50) (mean difference=±10.15 I 2 = 94.04%). No adverse events were reported across trials. Conclusion Perioperative dexmedetomidine infusion in obese patients undergoing bariatric surgery is a promising and safe alternative. Both intraoperative or postoperative infusions lead to significant opioid sparing in early and extend postoperative recovery phase. Morbidly obese patients receiving perioperative dexmedetomidine infusions have overall better pain control and lower incidence of postoperative nausea-vomiting. All the aforementioned merits come with a stable hemodynamic profile and without any reported major adverse events.

Metallic stents are being increasingly used for endoscopic drainage of peripancreatic fluid collections (PFCs) but their superiority over plastic stents has not been proven. We carried out a meta-analysis to consolidate the results from available studies and to suggest evidence-based recommendations. Studies that compared plastic and metallic stents for endoscopic drainage of PFCs and published before October 2016 were searched. Comparisons were performed for clinical success, adverse events, salvage interventions, mortality, technical success and recurrence. We included six studies with 856 patients (479 in the metallic stent group and 377 in the plastic stent group). The clinical success rate was significantly higher with metallic stents than with plastic stents (Mantel-Haenszel odds ratio [MH-OR] 3.22; 95% CI 1.87–5.54; P

Background: Gallbladder carcinoma (GBC) exhibits poor prognosis due to its detection at an advanced stage. Upregulation of lysosomal cysteine proteases cathepsin L (CTSL) and cathepsin B (CTSB) has been implicated in several tumorigenic processes. However, no such information in GBC was available. Therefore, the present study was planned to investigate the expression and clinical significance of these cathepsins in GBC.Methods: Activities of CTSL and CTSB were assayed in the gallbladder (GB) tissues obtained from GBC patients (n = 43) and control subjects (n = 69). Protein and mRNA levels were quantified using immunohistochemistry and real-time PCR (qPCR), respectively. Finally, serum levels of CTSL and CTSB were estimated by ELISA. Receiver operating characteristic (ROC) curve analysis was used for the assessment of sensitivity, specificity, and diagnostic accuracy of these cysteine cathepsins in GBC. The association of combined CTSL and CTSB activity with overall survival was assessed using Kaplan Meier survival analysis.Results: The expression and activity of both CTSL and CTSB were significantly increased (p < 0.050) in tumors of GBC patients as compared to controls. Enzymatic activity of CTSL+B and CTSB exhibited a strong positive association with tumor stage and lymph node involvement in GBC (p < 0.050). Interestingly, the elevated activity of combined CTSL+B was also associated with increased mortality in these patients. Furthermore, significantly enhanced levels of serum CTSL and CTSB were also observed in GBC (p < 0.050) as compared to controls. ROC analysis revealed high diagnostic significance of serum CTSB and CTSL for distinguishing GBC patients from controls with an area under the curve (AUC) of 82 and 77%, respectively.Conclusion: This study, for the first time, demonstrates the clinical significance of CTSL and CTSB overexpression in GBC. Our findings may help improve the clinical management of this carcinoma.

The aim of the study was to find out the carbapenem resistance rate and prevalence of different carbapenemase genes in

Context: Cysts arising from the hepatobiliary tree are a group of heterogeneous lesions with regard to pathogenesis, clinical presentation, and radiological finding. They can be intrahepatic or extrahepatic, developmental, secondary to infective/inflammatory etiologies, as well as neoplastic. This study was conducted to determine the spectrum of hepatobiliary cysts in surgically intervened cases, with regard to their prevalence, histological spectrum, and clinicoradiological correlation, wherever possible. Methods: In this retrospective observational study, hematoxylin and eosin stained slides of all cases of hepatobiliary cystic lesions, operated between 2009 and 2016 were reviewed. Special stains as reticulin, Masson's trichrome, and periodic acid Schiff were done wherever necessary. Overall prevalence, age-sex distribution, clinical presentation and histopathological patterns were studied. Relevant imaging findings were correlated wherever possible. Results: A total of 312 cases of hepatobiliary cysts were identified, the majority in females. Choledochal cysts (CCs) were the most common type (n = 198,63.5%), followed by hydatid cysts (n = 73,23.3%), simple hepatic cysts (n = 10,3.2%), congenital hepatic fibrosis (n = 10,3.2%), biliary cystadenomas (n = 4,1.2%) hepatic mesenchymal hamartomas (n = 7,2.2%), and cavernous hemangiomas (n = 3,0.9%). Fibropolycystic liver disease (n = 2,0.6%), Caroli's disease (n = 1, 0.3%), liver abscess (n = 2, 0.6%), infantile hemangioendothelioma (n = 1,0.3%), and biliary cystadenocarcinomas (n = 1,0.3%) were rare. Lesions noted mostly in 1st decade of life were: CCs, fibrocystic liver disease, Caroli's syndrome, cystic mesenchymal hamartoma, and infantile hemangioendotheliomas. Conclusion: In our cohort of surgically intervened cases of hepatobiliary cystic lesions from a tertiary care hospital in North India, the CCs, followed by hydatid cyst were the most common lesions. Histology can play vital role in characterization, as often clinical findings and radiology can overlap.

Application of the enhanced recovery after surgery (ERAS) to the bariatric surgical procedures is at its early stages with little consolidated evidence. This meta-analysis evaluates present literature and indicates pathways for development of evidence-based standardized ERAS protocols for bariatric surgery. Comparative trials between ERAS and conventional bariatric surgery published till June 2016 were searched in the medical database. Comparisons were made for length of stay (LOS), readmission, complications (major/minor), and reoperation rates. Trial sequential analysis (TSA) for the strength of meta-analysis was performed for the primary outcome LOS. Five subgroups with a total of 394 and 471 patients in ERAS and conventional group respectively were included. LOS was shorter in ERAS group by 1.56 ± 0.18 days (random-effects, p

There are no large series on hepatic resection for hepatocellular carcinoma (HCC) from India. We present the results of consecutive patients of HCC treated with hepatic resection at a tertiary care center in India.The records of all patients who underwent hepatic resection for HCC in the Department of Gastrointestinal Surgery, All India Institute of Medical Sciences (New Delhi), were reviewed. The relevant perioperative and follow up data were extracted from a prospectively maintained database.Between January 1987 and December 2013, 81 patients [71 males; mean age: 49.2 ± 15.6 years] underwent hepatic resection for HCC. Of these, 23 (28 %) were cirrhotic and 36 (49 %) had hepatitis B. Hepatitis B was significantly more common in cirrhotic (77 % vs. 37 %; p = 0.001). Most patients had locally advanced disease at presentation [tumor size ≥10 cm in 61 (75 %); vascular tumor thrombus in 10 (12 %)]. Anatomical resection was done in 61 (75 %) including 56 major hepatic resections (≥3 segments). Overall in-hospital mortality was 13 (16 %) [cirrhotic 5 (22 %) vs. noncirrhotic 8 (14 %), p = 0.503]. Grade III-V complications (modified Clavien-Dindo classification) occurred in 25 (31 %) patients (cirrhotic 48 % vs. noncirrhotic 24 %; p = 0.037). Follow up information was available for 51 (75 %) patients. The median time to recurrence was 12 months, and most (86 %) occurred within 1 year. The recurrence-free survival at 1, 3, and 5 years was 48 %, 40 %, and 36 %, respectively. Positive resection margin and vascular invasion were significantly associated with very poor prognosis.Majority of Indian HCC patients present with locally advanced disease. Despite this, surgical resection provides a chance for long-term recurrence-free survival in a third of them.

Introduction Heterotopic pancreas (HP) has rarely been identified in the wall of choledochal cyst (CC). Methods Retrospectively we screened 200 excised specimens of CC received at our Institute over a period of last eight years and looked for presence of HP rests in them. All the specimens were processed in their entirety. Result HP was identified in the wall of 13 (6.5%) CCs, out of which 11 were Heinrich Type 2, and two were Heinrich Type 1. In half of the cases peribiliary mucous glands were observed intermingled with the HP rests. Features of chronic fibrosing pancreatitis were identified in these rests, with ulceration of overlying cyst lining. Conclusions HP rests in the wall of CC though rare; their coexistence with peribiliary glands may possibly indicate their common embryonic origin. As a common site of inflammation, HP rest may be one of the common causes of CC.

Complete surgical resection is the best treatment option for retroperitoneal sarcomas even if it entails a multi-visceral resection. The extent of surgery is determined not only by the aggressiveness of the tumour but also by its location. This report presents a challenging case of retroperitoneal sarcoma and describes the planning and decision-making that resulted in the success of such an extensive surgical procedure.

Cholecystectomy preferably laparoscopy is gold standard treatment for symptomatic cholelithiasis. However for some anatomical and/or pathological reasons the procedure is converted to open. Conversion rates at high volume centres is

Dexamethasone has many desirable pharmacologic properties for perioperative use. Its antiemetic potential has been a focus of many recent trials. Trials comparing dexamethasone to 5-HT3-receptor antagonists (5HT3-RA) for 24 h postoperative vomiting incidences published till August 2017 were searched in the medical database. Comparisons for antiemetic efficiency variables (vomiting incidence, nausea incidence, rescue antiemetic need, and patients with complete response) during early (until 6 h) and late postoperative phase were made. Comparative analgesic requirements were also evaluated. Twenty randomized controlled double-blinded trials were included in the final analysis. Twenty-four-hour vomiting incidence was similar (Fixed-effects, P = 0.86, I2 = 2.94%). Trial sequential analysis (TSA) confirmed non-inferiority of dexamethasone for 24-h vomiting incidence. (α = 5%, β = 20%, δ = 10%) with “information size” being 1619 (required > 573). Equivalence was also verified from early and delayed nausea rate as well using TSA. Pooled results did not demonstrate superiority/inferiority of 5-HT3-RAs over dexamethasone in all other antiemetic efficacy variables (early and delayed). Heterogeneity was found to be low in all of the comparisons. Linear-positive dose-response curve for dexamethasone 24-h vomiting and nausea incidence was seen (correlation coefficient being 0.21 and 0.28, respectively). Dexamethasone reduced the analgesic need (MH-odds of 0.64 (95% CI being 0.44 to 0.93) P = 0.02, I2 = 0)). Possibility of publication bias could not be ruled out (Egger’s test, X-intercept = 1.41, P = 0.04). Dexamethasone demonstrates equal antiemetic efficacy compared to 5-HT3 receptor antagonists. The agents perform equally well both in early postoperative phase and up to 24 h after surgery. Use of dexamethasone replacing 5-HT3 RAs offers an additional advantage of lowering the opioid requirements during the perioperative period.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract and may occasionally present with acute gastrointestinal bleed (GIB). Multidetector computed tomography (MDCT) angiography is extremely useful in demonstrating the tumor as well as the presence of active hemorrhage, thereby guiding subsequent interventional or surgical management. We report a case of a 38-year-old man who presented with acute-onset melena and compensated shock, whose source of bleed remained elusive on endoscopy. MDCT angiography performed on a dual-energy scanner showed a jejunal tumor with active intraluminal contrast extravasation. The tumor was subsequently resected and the patient did well on follow-up. This was one of the few instances when MDCT angiography demonstrated active bleeding in a GIST and the first such case demonstrated on a dual-energy scanner.

Up to a third of patients with acute severe ulcerative colitis (ASUC) fail to respond to intensive steroid therapy and eventually require a salvage colectomy. We have previously reported that the mortality of emergency colectomy can be decreased by offering it within the first week of intensive medical therapy. We implemented this policy and report the results of our experience. The clinical records of all patients with ASUC who underwent emergency colectomy after failure of medical therapy between January 2005 and July 2015 were extracted from a prospectively maintained database. The data were analysed with regard to duration of intensive medical therapy, timing of surgery, in-hospital mortality and post-operative complications. Eighty-eight patients underwent emergency surgery for ASUC after failed medical therapy. Of these, 75 (85.2%) were operated within 7 days of initiation of intensive medical therapy [n = 51 (58%) were operated

There are no large series on hepatic resection for hepatocellular carcinoma (HCC) from India. We present the results of consecutive patients of HCC treated with hepatic resection at a tertiary care center in India. The records of all patients who underwent hepatic resection for HCC in the Department of Gastrointestinal Surgery, All India Institute of Medical Sciences (New Delhi), were reviewed. The relevant perioperative and follow up data were extracted from a prospectively maintained database. Between January 1987 and December 2013, 81 patients [71 males; mean age: 49.2 ± 15.6 years] underwent hepatic resection for HCC. Of these, 23 (28 %) were cirrhotic and 36 (49 %) had hepatitis B. Hepatitis B was significantly more common in cirrhotic (77 % vs. 37 %; p = 0.001). Most patients had locally advanced disease at presentation [tumor size ≥10 cm in 61 (75 %); vascular tumor thrombus in 10 (12 %)]. Anatomical resection was done in 61 (75 %) including 56 major hepatic resections (≥3 segments). Overall in-hospital mortality was 13 (16 %) [cirrhotic 5 (22 %) vs. noncirrhotic 8 (14 %), p = 0.503]. Grade III–V complications (modified Clavien-Dindo classification) occurred in 25 (31 %) patients (cirrhotic 48 % vs. noncirrhotic 24 %; p = 0.037). Follow up information was available for 51 (75 %) patients. The median time to recurrence was 12 months, and most (86 %) occurred within 1 year. The recurrence-free survival at 1, 3, and 5 years was 48 %, 40 %, and 36 %, respectively. Positive resection margin and vascular invasion were significantly associated with very poor prognosis. Majority of Indian HCC patients present with locally advanced disease. Despite this, surgical resection provides a chance for long-term recurrence-free survival in a third of them.

Background A number of definitions have been used for delayed gastric emptying (DGE) after pancreatoduodenectomy and the reported rates varied widely. The International Study Group of Pancreatic Surgery (ISGPS) definition is the current standard but it is not used universally. In this comprehensive review, we aimed to determine the acceptance rate of ISGPS definition of DGE, the incidence of DGE after pancreatoduodenectomy and the effect of various technical modifications on its incidence. Data source We searched PubMed for studies regarding DGE after pancreatoduodenectomy that were published from 1 January 1980 to 1 July 2015 and extracted data on DGE definition, DGE rates and comparison of DGE rates among different technical modifications from all of the relevant articles. Results Out of 435 search results, 178 were selected for data extraction. The ISGPS definition was used in 80% of the studies published since 2010 and the average rates of DGE and clinically relevant DGE were 27.7% (range: 0–100%; median: 18.7%) and 14.3% (range: 1.8%–58.2%; median: 13.6%), respectively. Pylorus preservation or retrocolic reconstruction were not associated with increased DGE rates. Although pyloric dilatation, Braun's entero-enterostomy and Billroth II reconstruction were associated with significantly lower DGE rates, pyloric ring resection appears to be most promising with favorable results in 7 out of 10 studies. Conclusions ISGPS definition of DGE has been used in majority of studies published after 2010. Clinically relevant DGE rates remain high at 14.3% despite a number of proposed surgical modifications. Pyloric ring resection seems to offer the most promising solution to reduce the occurrence of DGE.

Background Knowledge, sociocultural views, and awareness about organ donation in the general population are important for the success of deceased organ donation. There is an urgent need to gather this information in order to find out the reasons for poor organ donation rates in India. Methods A 30-item questionnaire was designed in the English and Hindi language and was administered to the lay people in order to assess their knowledge, views, and attitude regarding brain death and organ donation. Results Three hundred and fifty-two people (male:female = 202:150; mean age = 30.6 ± 13.9 years) completed the questionnaire. Only 70% of the people were aware that the organs can be donated after brain death and only 44% thought that they understood the meaning of brain death. Media and Internet were the preferred sources for seeking information on brain death and organ donation. The majority of people (81.2%) were willing to donate organs after brain death but only 1.4% had registered for organ donation. Lack of awareness (80.1%), religious beliefs and superstitions (63.4%), and lack of faith in the healthcare system (40.3%) were believed to be the most important reasons for poor deceased organ donation rates in India. The survey also highlighted the importance of the opinion of family members and the religious leaders in making the decision for organ donation. Educational qualification above matriculation was significantly associated with the knowledge of brain death and the willingness for organ donation. Conclusion Lack of awareness appears to be the most important factor for low donation rates in India. Educating people by using media and Internet and conducting awareness programs may help in improving the donation rates.
