Factors Predicting Prognosis in Metastatic Grade 1 Gastro-entero-pancreatic Neuroendocrine Tumors.

INTRODUCTION: The incidence of gastroenteropancreatic neuroendocrine tumors (GEP-NET) has steadily increased. These tumors are considered relatively indolent even when metastatic. What determines survival outcomes in such situations is understudied. MATERIALS AND METHODS: Retrospective analysis of a prospectively maintained NET clinic database, to include patients of metastatic grade 1 GEP-NET, from January 2018 to December 2021, to assess factors affecting progression-free survival (PFS). RESULTS: Of the 589 patients of GEP-NET treated during the study period, 100 were grade 1, with radiological evidence of distant metastasis. The median age was 50 years, with 67% being men. Of these, 15 patients were observed, while 85 patients received treatment in the form of surgery (n = 32), peptide receptor radionuclide therapy (n = 50), octreotide LAR (n = 22), and/or chemotherapy (n = 4), either as a single modality or multi-modality treatment. The median (PFS) was 54.5 months. The estimated 3-year PFS and 3-year overall survival rates were 72.3% (SE 0.048) and 93.4% (SE 0.026), respectively. On Cox regression, a high liver tumor burden was the only independent predictor of PFS (OR 3.443, p = 0.014). The 5-year OS of patients with concomitant extra-hepatic disease was significantly lower than that of patients with liver-limited disease (70.7% vs. 100%, p = 0.017). CONCLUSION: A higher burden of liver disease is associated with shorter PFS in patients with metastatic grade I GEP-NETs. The OS is significantly lower in patients with associated extrahepatic involvement. These parameters may justify a more aggressive treatment approach in metastatic grade 1 GEP-NETs.

Practice Patterns and Survival in Patients with Resected Pancreatic Ductal Adenocarcinomas (PDAC) - Results from the Multicentre Indian Pancreatic & Periampullary Adenocarcinoma Project (MIPPAP) Study.

BACKGROUND: There is limited data from India with regard to presentation, practice patterns and survivals in resected pancreatic ductal adenocarcinomas (PDACs). METHODS: The Multicentre Indian Pancreatic & Periampullary Adenocarcinoma Project (MIPPAP) included data from 8 major academic institutions across India and presents the outcomes in upfront resected PDACs from January 2015 to June 2019. RESULTS: Of 288 patients, R0 resection was achieved in 81% and adjuvant therapy was administered in 75% of patients. With a median follow-up of 42 months (95% CI: 39-45), median DFS for the entire cohort was 39 months (95% CI: 25.4-52.5), and median overall survival (OS) was 45 months (95% CI: 32.3-57.7). A separate analysis was done in which patients were divided into 3 groups: (a) those with stage I and absent PNI (SI&PNI-), (b) those with either stage II/III OR presence of PNI (SII/III/PNI+), and (c) those with stage II/III AND presence of PNI (SII/III&PNI+). The DFS was significantly lesser in patients with SII/III&PNI+ (median 25, 95% CI: 14.1-35.9 months), compared to SII/III/PNI + (median 40, 95% CI: 24-55 months) and SI&PNI- (median, not reached) (p = 0.036)). CONCLUSIONS: The MIPPAP study shows that resectable PDACs in India have survivals at par with previously published data. Adjuvant therapy was administered in 75% patients. Adjuvant radiotherapy does not seem to add to survival after R0 resection.

Factors predicting 30-day mortality after pancreaticoduodenectomy-the impact of elevated aspartate aminotransferase.

PURPOSE: High preoperative bilirubin levels and cholangitis are associated with poor peri-operative outcomes following pancreaticoduodenectomy (PD). However, the impact of deranged preoperative aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels on immediate postoperative outcomes is relatively unexplored. We hypothesized that deranged AST and ALT lead to worse postoperative outcomes after PD. The aim of this study was to assess the factors contributing to postoperative mortality (POM) following PD, and to study the impact of deranged aminotransferases. METHODS: This is a retrospective analysis of 562 patients. Risk factors for POM were computed using a multivariate logistic regression model. RESULTS: The rate of POM was 3.9%. On univariate analysis, the American Society of Anaesthesiologists grades, diabetes mellitus, cardiac comorbidity, preoperative biliary stenting, elevated serum bilirubin, AST, elevated serum creatinine, clinically relevant pancreatic fistula (CRPF), and grade B+C post-pancreatectomy hemorrhage (PPH) were associated with 30-day mortality. On multivariate analysis, preoperative elevated AST was independently predictive of 30-day POM (OR = 6.141, 95%CI 2.060-18.305, p = 0.001). Other factors independently predictive of POM were elevated serum creatinine, preoperative biliary stenting, CRPF and grade B and C PPH. The ratio of AST/ALT > 0.89 was associated with 8 times increased odds of POM. CONCLUSION: Elevated preoperative AST emerged as a predictor of 30-day POM after PD, with an 8-times increased odds of death with an AST/ALT ratio > 0.89.

Gastrointestinal complications (gangrene or perforation) after corona virus disease 2019 - A series of ten patients.

During the recent second wave of corona virus disease 2019 (COVID-19) pandemic in India, we managed a series of gastrointestinal complications in patients with COVID-19. We aim to highlight the key presentation and clinical course and emphasize the lessons we learnt from our series of such patients. A case review of ten consecutive patients with either bowel gangrene or perforation who were managed at our centre from March 20, 2021 to June 10, 2021. Clinical-demographic details, possible etiology, radiological findings, management and outcomes have been described. Of the 10 patients, 2 presented with bowel gangrene and 8 with perforation. In our series, all these patients were diagnosed with the help of computed tomography (CT) abdomen during the 3rd week after diagnosis of COVID-19. All had received steroid medication. Both patients with bowel gangrene and 4 of 8 patients with perforation underwent surgery, while 4 were managed non-operatively. Barring one patient, all the operated patients succumbed within 5 days of surgery after rapid clinical deterioration. Non-operative management in selected patients with perforation including placement of percutaneous drains, bowel rest and antibiotics was successful. Emergency surgery for COVID-19 related intestinal gangrene or perforation was associated with high mortality in our series. Non-operative management which avoids the added stress of a major emergency surgery particularly in patients just recovering from COVID-19 may be considered in stable patients in whom perforation appears to be contained.

Can we predict the need for nutritional support following pancreatoduodenectomy?

BACKGROUND: The practice of routine placement of a tube jejunostomy at the time of pancreatoduodenectomy has given way to a more selective approach. However, the indications of establishing enteral access at the time of surgery remain poorly defined. This study aimed to assess the preoperative and intraoperative factors associated with the need for nutritional support after pancreatoduodenectomy, to guide decision-making for the establishment of intraoperative feeding access. METHODS: Retrospective study, analyzing the data of 562 consecutive patients, who underwent pancreatoduodenectomy between March 2013 to December 2020. Univariate and multiple logistic regression analysis was carried out to ascertain the factors associated with the initiation of and need for nutritional support for more than 7 days postop. The utility of tube jejunostomy was studied in patients in whom it was performed. RESULTS: Of 562 patients, 105 (18.7%) needed nutritional support. A tube jejunostomy was performed in 46 (8.2%) patients, parenteral nutrition was used in 83 (14.8%), and nasojejunal tube placed in 28 (4.9%) patients. On logistic regression analysis, age, serum albumin <3.0 gm/dl and operative blood loss were independently associated with the initiation of supportive nutrition, while preoperative gastric outlet obstruction (OR 3.105, 95% CI1.201-8.032, p = 0.019) and serum albumin <3.0 gm/dl (OR 2.669, 95% CI 1.131-6.300, p = 0.025) were associated with the need for prolonged nutritional support. The maximal benefit of tube jejunostomy was in patients with mental health disorders (83.3%). CONCLUSION: Tube jejunostomy for nutritional support after pancreatoduodenectomy can be considered in patients with preoperative gastric outlet obstruction, serum albumin <3.0 gm/dl and mental health disorders.

Enhanced recovery after pancreatoduodenectomy-does age have a bearing?

INTRODUCTION: With the proven benefits of enhanced recovery protocols (ERP) after pancreatoduodenectomy (PD), their implementation has become a well-accepted clinical practice across the major pancreatic surgery centres of the world. The impact of age on the execution of ERP has remained an area of ambiguity. The aim of this study was to assess the impact of age on the feasibility of various postoperative elements of ERP after PD. METHODS: A retrospective study was conducted which included 548 patients undergoing PD, managed using ERP, from March 2013 to September 2020. Patients were divided into two groups: < 70 years and ≥ 70 years. Compliance to recovery parameters and postoperative outcomes, including, the incidence of major complications, length of stay (LOS), mortality rates and re-admissions, were compared between the two groups. The impact of age, as a continuous variable, was also studied on the feasibility of each postoperative element. RESULTS: One-fifth (113/548) of the cohort comprised of patients aged 70 years and above. The 'elderly' patients had a significantly higher prevalence of diabetes, hypertension, and cardiac disease. They were also more likely to get admitted to the intensive care unit for postoperative monitoring (p < 0.001). The median LOS was 8.0 days in the young and 9.0 days in the elderly (p = 0.253). Rate of major complications (age < 70, n = 37 (8.5%) vs age ≥ 70, n = 7 (6.2%), p = 0.421) and 30-day mortality (age < 70, n = 15 (3.4%) vs age ≥ 70, n = 7 (6.2%), p = 0.185) was not statistically different between the two groups. Compliance of various postoperative elements was similar between the two groups. When studied as a continuous variable, age did not seem to be associated with higher non-compliance of any of the postoperative recovery elements. CONCLUSION: Age is not a barrier in the safe implementation of postoperative element of ERPs after PD. Enhanced recovery protocols do not need to be modified for the aged.

Elective Gastrointestinal Surgery in COVID Times.

With the COVID pandemic claiming deaths the world over, the healthcare systems were overburdened. This led to the cancellation and delay in elective surgical cases which can have far-reaching consequences This study reports our experience of elective gastro-intestinal surgical procedures during the COVID pandemic, after instating preventive strategies and screening protocols to prevent the transmission of COVID infection. This is a case series analysis of elective gastro-intestinal surgical procedures performed from March 24, 2020, to July 31, 2020. During this period, 314 gastro-intestinal surgical procedures were performed; of which, 45% were for malignancies. The median age of patients was 54 years (range 8 to 94 years). Laparoscopy was used in 43% cases. Major postoperative complications (Clavien-Dindo grade 3 and above) were witnessed in 3.5% (11/314) patients, with no statistically significant difference when compared with the rate of major complications last year (45/914, 4.9% vs 11/314, 3.5%, p = 0.3). The 30-day mortality rate was 1% (n = 3). No patient developed COVID in the postoperative period. With preventive and screening strategies and proper patient selection, it is possible to deliver safe GI surgical services during the COVID pandemic, without increasing the risk for major postoperative complications.

Deviations from a clinical pathway post pancreatoduodenectomy predict 90-day unplanned re-admission.

Aim: To determine the frequency and relevance of deviations from a post pancreatoduodenectomy (PD) clinical care pathway. Materials & methods: A retrospective analysis using a prospectively maintained database of a post-PD clinical care pathway was carried out between May 2016 and March 2018. Patients were divided based on the number of factors deviating from the clinical care pathway (Group I: no deviation; Group II: deviation in 1-4 factors; Group III: deviation in 5-8 factors). The analysis included profiling of patients on different demographic and clinical as well as medical and surgical outcome parameters (discharge by postoperative day 8 and 90-day unplanned re-admission rate). Results: Post-PD clinical care pathways are feasible but deviations from the pathway are frequent (91%). An increase in frequency of deviations from the pathway was significantly associated with increased risk of POPF and delayed gastric emptying, delayed discharge, risk of mortality and 90-day unplanned re-admission rate. Conclusion: Deviations from a post-PD clinical care pathway are common. Poor nutrition and cardiac co-morbidities are associated with an increased likelihood of deviation. As the number of deviations increase, so does the risk of significant complications and interventions, delayed discharge and 90-day re-admission rate.

Iron status of children aged 9-36 months in an urban slum Integrated Child Development Services project in Delhi.

OBJECTIVE: To assess the magnitude/severity and possible etiology of anemia and iron deficiency among children 9-36 months of age. METHODS: A population-based study on the prevalence, etiology of anemia and iron status in 545 children, 9-36 months of age, was conducted in an urban slum ICDS (Integrated Child Development Services) project in North-East Delhi. Hemoglobin and serum ferritin was estimated and information on socio-economic, demographic, parasitic infection/infestation and dietary intake was collected. RESULTS: Prevalence of anemia (using WHO cut-off values of Hb >11.0 g/dl) among children, 9-36 months of age, was 64%, of these 7.8% had severe anemia (Hb >7.0 g/dl). Using 10.0 g/dl as the Hb cut-off point 44% children less than 18 months of age in the present study population were anemic. On a sub-sample study, 88% children were estimated to be iron deficient, with serum ferritin concentration less than 12 microg/L. The peripheral smear red cell morphology showed 33.9% as microcytic-hypochromic and 37.1% as dimorphic. Dimorphic anemia was 55% in moderate anemia group. The energy and iron intakes were 56% and 45%, respectively of the Recommended Dietary Allowances (RDA). The parasitic infestation/infection was not related to the prevalence or severity of anemia. CONCLUSION: In Delhi, high prevalence of moderate to severe anemia and iron deficiency with vitamins folate and/or B12 among children under 3 years of age in an ICDS block in operation for 20 years is of concern. Dietary origin was the main cause of anemia in this age group.
