Prognostic risk factors in 113 patients undergoing cephalic duodenopancreatectomy for distal cholangiocarcinoma. / Factores de mal pronóstico en 113 pacientes sometidos a duodenopancreatectomía cefálica por colangiocarcinoma distal.

INTRODUCTION: Distal cholangiocarcinoma is a malignant epithelial neoplasia that affects the extrahepatic bile ducts, below the cystic duct. No relevant relationship between perioperative factors and worse long-term outcome has been proved. OBJECTIVE: To analyze the risk factors for mortality and long-term recurrence of distal cholangiocarcinoma in resected patients. MATERIALS AND METHODS: A single-center prospective database of patients operated on for distal cholangiocarcinoma between 1990 and 2021 was analyzed in order to investigate mortality and recurrence factors. RESULTS: One hundred and thirteen patients have undergone surgery, with mean actuarial survival of 100.2 (76-124) months after resection. The bivariate study did not show differences between patients depending on age or preoperative variables studied. When multivariate analysis was performed, the presence of affected adenopathy was a risk factor for long-term mortality. The presence of affected lymph nodes, tumor recurrence, and biliary fistula during the postoperative period implied worse actuarial survival when comparing the Kaplan-Meier curves. CONCLUSIONS: The presence of affected lymph nodes influence the prognosis of the disease. The occurrence of biliary fistula during postoperative cholangiocarcinoma distal could aggravate long-term outcomes, a finding that should be reaffirmed in future studies.

Combined endoscopic-laparoscopic surgery (CELS) can avoid segmental colectomy in endoscopically unremovable colonic polyps: a cohort study over 10 years.

BACKGROUND: Combined-Endoscopic-Laparoscopic-Surgery (CELS) was developed for benign colonic polyps, endoscopically unresectable, to avoid segmental colectomy. This observational study aims to compare surgical outcomes of endoscopically unresectable colonic polyps treated laparoscopically before and since the institutional introduction of CELS. Primary endpoint was postoperative morbidity and mortality; secondary endpoints were time of hospitalization and histopathological findings. METHODS: Charts of all patients with preoperative diagnosis of benign colonic tumors, treated laparoscopically at our institution from 1/2010 to 2/2020 were reviewed. Patients with polyps (1) affecting ileocecal valve, (2) occupying > 50% of the circumference, (3) ≥ 3 endoscopically unresectable polyps, (4) inflammatory bowel disease, (5) polyps within diverticular area post diverticulitis, (6) rectal polyps (7) foreseen impossibility of laparoscopy (8) preoperatively biopsy proven invasive adenocarcinoma were excluded. Group I consists of all patients potentially treatable by CELS but operated by laparoscopic colonic resection as CELS was not yet institutionally established. Group II includes all patients treated with CELS (since 11/2017). RESULTS: One hundred-fifteen consecutive patients were reviewed. Applying exclusion criteria, twenty-three patients form group I and twenty-three group II (female 30.4%, median age 68 years). Groups distributed homogenously for age, BMI (body mass index) and polyps´ localization with most polyps (60.4%) localized in right colon; group II patients had significantly higher American Society of Anesthesiologists (ASA) score. Median operating time, hospital stay and morbidity were significantly less in group II. Postoperative morbidity occurred overall in 14 patients (30.4%), mostly Clavien-Dindo class I-II (26.1%) and significantly less in group II (p = 0.017), Clavien-Dindo III-IV distributed equally (one patient each group) without postoperative mortality. Definitive histopathology showed invasive adenocarcinoma in 8.3% without differences between groups. Two patients with invasive adenocarcinoma after CELS were advised for oncological resection. CONCLUSION: CELS is safe and efficient to treat complex, benign colonic polyps by a complete minimal invasive laparoscopic approach. CELS showed better surgical outcomes with less morbidity, no mortality and appropriate pathological results avoiding unnecessary laparoscopic surgery with intestinal anastomosis.

Incidence, features, outcome and impact on health system of de-novo abdominal surgical diseases in patients admitted with COVID-19.

OBJECTIVE: to assess the epidemiology and features of de novo surgical diseases in patients admitted with COVID-19, and their impact on patients and healthcare system. SUMMARY BACKGROUND DATA: Gastrointestinal involvement has been described in COVID-19; however, no clear figures of incidence, epidemiology and economic impact exist for de-novo surgical diseases in hospitalized patients. METHODS: This is a prospective study including all patients admitted with confirmed SARS-CoV-2 rT-PCR, between 1 March and 15 May 2020 at two Tertiary Hospitals. Patients with known surgical disease at admission were excluded. Sub-analyses were performed with a consecutive group of COVID-19 patients admitted during the study period, who did not require surgical consultation. RESULTS: Ten out of 3089 COVID-19 positive patients (0.32%) required surgical consultation. Among those admitted in intensive care unit (ICU) incidence was 1.9%. Mortality was 40% in patients requiring immediate surgery and 20% in those suitable for conservative management. The overall median length of stay (LOS) of patients admitted to ICU was longer in those requiring surgical consultation compared with those who did not (51.5 vs 25 days, p = 0.0042). Patients requiring surgical consultation and treatment for de-novo surgical disease had longer median ICU-LOS (31.5 vs 12 days, p = 0.0004). A median of two post-surgical complications were registered for each patient undergoing surgery. Complication-associated costs were as high as 38,962 USD per patient. CONCLUSIONS: Incidence of de-novo surgical diseases is low in COVID-19, but it is associated with significant morbidity and mortality. Future studies should elucidate the mechanism underlying the condition and identify strategies to prevent the need for surgery.

The involvement of the hepatic artery is a risk factor for unresectability after neoadjuvant treatment in borderline pancreatic adenocarcinoma.

INTRODUCTION: Borderline Resectable Pancreatic Ductal Adenocarcinoma (BR-PDAC) benefits from neoadjuvant treatment (NAT) with the intent of surgical salvage in the absence of disease progression during chemotherapy (CT) or chemoradiotherapy (CRT). Scarce literature exists about prognostic factors of resectability at the time of diagnosis or during neoadjuvant treatment, especially regarding vascular relationships. MATERIALS: We reviewed our prospective BR-PDAC cohort to determine resectability predictors. We collected data about clinical baseline characteristics, vessels' involvement, type of NAT, CA19-9 evolution, and radiological outcome. We performed a descriptive analysis and a logistic regression model to define resectability predictors; we finally compared overall survival (OS) and progression-free survival (PFS) for those predictors. RESULTS: One hundred patients started NAT, with a resection rate of 44 % (40 pancreaticoduodenectomies, 4 distal pancreatectomies). The most frequent vessel relationship was the abutment of the superior mesenteric artery (44 %), and 26 patients had ≥2 vessels involved. Prognostic factors of resectability were CA19-9 response >10 % (OR 3.07, p = 0.016) and Hepatic Artery involvement (OR 0.21, p = 0.026). Median overall survival was better for CA19-9 responders than for non-responders (20.9 months and 11.8 months respectively, p < 0.001), and similar to normalized CA19-9 (25.0 months, p = 0.48). There were no differences in terms of OS or PFS with the involvement of the HA (17.7 vs 17.1 months, p = 0.367; and 8.7 vs 12.0 months, p = 0.267). CONCLUSION: The involvement of the Hepatic Artery seems to confer a worse prognosis regarding resectability. A decrease of only >10 % of CA19-9 is a predictive factor for resectability and better overall and progression-free survival.

Experience in the resection of the uncinate process of the pancreas: Indications and results. Literature review.

INTRODUCTION: The aim of our study is to assess the accumulated experience in the use of uncinatectomy (UC) as a parenchymal-sparing pancreatectomy technique. METHOD: We have carried out a observational and descriptive study including restrospectively all the patients undergoing UC at Hospital Universitary de Bellvitge (HUB) and an exhaustive review of the cases described in the english literature. RESULTS: From 2003 to 2019, seven patients have been operated by UC in the HUB with a diagnostic orientation of pancreatic lesion considered premalignant. All patients have presented morbidity, mainly in the form of postoperative pancreatic fistula, and none of them have presented endocrine or exocrine pancreatic insufficiency. Currently, all patients are alive and without recurrence of neoplastic disease. Another 29 cases have been described in the literature. Of all the cases (36 patients), the approach was minimally invasive (laparoscopic or robotic) in 6 patients (16.7%), leading to a shorter hospital stay. The global incidence of pancreatic fistula is 50%, with a re-admission rate of less than 10%, but without requiring re-intervention. CONCLUSIONS: UC is an infrequent and poorly standardized technique for the resection of benign lesions or those with low potential for malignancy located in the uncinate process of the pancreas. Although it is associated with equal or greater morbidity than standardized resection techniques, it offers excellent preservation of endocrine and exocrine pancreatic function, with the consequent long-term benefit in the patients life quality.

Home monitoring vs hospitalization for mild acute pancreatitis. A pilot randomized controlled clinical trials.

INTRODUCTION: Acute pancreatitis is a high-incidence benign disease. In 2009, it was the second highest cause of total hospital stays, the largest contributor to aggregate costs (approximately US$ 7000.00 per hospitalization), and the fifth leading cause of in-hospital deaths in the United States. Although almost 80% of acute pancreatitis cases are mild (usually requiring short-term hospitalization and without further complications), severe cases can be quite challenging.Classifications, scores, and radiological criteria have been developed to predict disease severity and outcome accurately; however, in-hospital care remains of widespread use, regardless of disease severity. A recent Turkish study reported that mild acute pancreatitis can be effectively and safely managed with home monitoring. Although the optimal timing for oral refeeding remains controversial and could cast some doubt on the feasibility of home monitoring, some guidelines already advocate for starting it within 24 hours.The present clinical trial aims to assess whether home monitoring is effective, safe and non-inferior to hospitalization for managing mild acute pancreatitis. METHODS: This will be a multicenter open-label randomized (1:1) controlled clinical trial to assess the efficacy and safety of home monitoring compared to in-hospital care for mild acute pancreatitis. All patients coming to the emergency department with suspected acute pancreatitis will be screened for enrollment. The main variable will be treatment failure (Yes/No) within the first 7 days after randomization. DISCUSSION: Acute pancreatitis implies a high economic burden in healthcare systems worldwide. Recent evidence suggests that mild disease can be safely and effectively treated with home monitoring. This approach may produce considerable cost savings and positively impact patients' quality of life. We expect the results to show that home monitoring is effective and not inferior to hospitalization for managing mild acute pancreatitis and that the economic costs are lower, kickstarting similar trials throughout the world, optimizing the use of limited healthcare budgets, and improving patients' quality of life.

Surgical options for the treatment of neuroendocrine neoplasms of the ampulla of Vater: a reference centre experience.

INTRODUCTION: The main objective of this study was to analyse the results of the surgical treatment of ampullary neuroendocrine tumours (NET) based on transduodenal ampullectomy and pancreatoduodenectomy, in a reference centre in hepatobiliopancreatic pathology. METHOD: Retrospective, observational study, including all patients operated on for pancreatic and/or duodenal NET in a reference unit of hepatobiliopancreatic pathology and prospectively registered between January 1st, 1993 and September 30th, 2021. For those parameters not present, retrospective research was performed. Demographic, clinical, analytical and pathological data were analysed. A descriptive study was carried out. Overall and disease-free survival was calculated using Kaplan-Meier curves and the Log-Rank test. RESULTS: Of 181 patients operated on for pancreatic and/or duodenal NET, only 9 were located in the ampulla of Vater, which represents 4.9% of all pancreatic and/or duodenal NET. Pancreatoduodenectomy (PD) was performed in 6 patients, while 3 patients underwent transduodenal ampullectomy (TDA). Longer surgical time and more postoperative complications were observed in the PD group. There were no differences in hospital stay. Overall and disease-free survival at 5 years in the PD group compared to ATD was 83.3% vs. 100% and 50% vs. 100%, respectively. CONCLUSIONS: Ampullary NET without locoregional involvement or risk factors, can be treated by conservative surgeries such as transduodenal ampullectomy.

Experience in biliopancreatic diversion with duodenal switch: Results at 2, 5 and 10 years.

INTRODUCTION: Duodenal switch (DS) is considered one of the most effective techniques to achieve weight loss and reduce comorbidities in patients with morbidly obesity. MATERIAL AND METHODS: Descriptive single-center study. 224 patients were analyzed who underwent direct laparoscopic DS in our center. The objective was to describe the results of weight, resolution of comorbidities, nutritional supplementation and postoperative complications at 2, 5 and 10 years. RESULTS: The mean age of the cohort was 49.3 [23-65] years and the mean weight and BMI were 131.8 [20] kg and 49.8 [5] kg/m2. The excess weight lost percentage at 2, 5 and 10 years was 80.6[15]%, 69.3[18]%, 67.4[18]%, respectively. Complete remission of diabetes was evidenced at 2 and 5 years in 35 (85.4%) and 27 (70.4%) patients. In the immediate postoperative period, the complication rate for Clavien-Dindo ≥ III was 15 patients (6.7%) and mortality at 30 and 90 days was 1 (0.4%) and 2 (0.9%) patients. Revisional surgery was performed in 2 patients (0.9%). 80% of the patients required an extra nutritional supplement up to 10 years after surgery. CONCLUSIONS: Direct DS is a safe and effective technique in patients with a BMI between 45 and 55 kg/m2. Weight loss is maintained with a low rate of revision surgery. It is a metabolically effective technique that entails the need for a close postoperative follow-up to assess nutritional supplementation.

Predictive factors for resection and survival in type A borderline resectable pancreatic ductal adenocarcinoma patients after neoadjuvant therapy: A retrospective cohort study.

INTRODUCTION: Pancreatic cancer is the seventh leading cause of cancer-related death worldwide, and surgical resection with radical intent remains the only potentially curative treatment option today. However, borderline resectable pancreatic ductal adenocarcinomas (BR-PDAC) stand in the gray area between the resectable and unresectable disease since they are technically resectable but have a high probability of incomplete exeresis. Neoadjuvant treatment (NAT) plays an important role in ensuring resection success.Different survival prognostic factors for BR-PDAC have been well described, but evidence on the predictive factors associated with resection after NAT is scarce. This study aims to study if CA 19-9 plasmatic levels and the tumor anatomical relationship with neighboring vascular structures are prognostic factors for resection and survival (both Overall Survival and Progression-Free Survival) in patients with type A BR-PDAC. METHODS: This will be a retrospective cohort study using data from type A BR-PDAC patients who received NAT in the Bellvitge University Hospital. The observation period is from January 2010 until December 2019; patients must have a minimum 12-month follow-up. Patients will be classified according to the MD Anderson Cancer Center criteria for BR-PDAC. DISCUSSION: Patients with BR-PDAC have a high risk for a margin-positive resection. Serum Carbohydrate Antigen 19-9 plasmatic levels and vascular involvement stand out as disease-related prognostic factors.This study will provide valuable information on the prognostic factors associated with resection. We will exclude locally advanced tumors and expect this approach to provide more realistic resection rates without selecting those patients that undergo surgical exploration. However, focusing on an anatomical definition may limit the results' generalizability.

Oral health and gastrointestinal neoplasia: Narrative review. / Salud oral y neoplasia gastrointestinal. Revisión narrativa.

The oral cavity represents the gateway to the complex digestive system, so the knowledge of the exact mechanisms that link them is vitally important. Recently, oral and dental pathologies have been studied as potential risk factors for pathologies linked to lifestyle habits. Therefore, it could be considered as an interesting preventive way. We conducted a narrative review with a thorough bibliographic search on MEDLINE and SCOPUS, including international studies related to oral healthcare and gastrointestinal neoplasms, published between 2015 and 2020. The primary aim of this revision is to analyze the association between oral healthcare and carcinogenic gastrointestinal processes, providing a possible future preventive strategy for dental care. Moreover, we intend to raise awareness about the importance of oral healthcare as a new paradigm and study variable in the global health care system.

Direct and two-step single anastomosis duodenal switch (SADI-S): Unicentric comparative analysis of 232 cases.

INTRODUCTION: The "Single Anastomosis Duodeno-Ileal bypass with Sleeve gastrectomy" (SADI-S) is a bariatric surgery conceived to simplify the duodenal switch in order to reduce its postoperative complications. The objective of this study is to assess the safety and efficacy of SADI-S, comparing its results in both direct and two-step procedure. METHODS: Unicentric cohort study that includes patients submitted to SADI-S, both direct or in two-step, between 2014 and 2019. RESULTS: Two hundred thirty-two patients were included, 192 were submitted to direct SADI-S and 40 had previously undergone a sleeve gastrectomy. The severe complications rate (Clavien-Dindo ≥ IIIA) was 7.8%, being hemoperitoneum and duodenal stump leak the most frequent ones. One patient was exitus between the first 90 days after surgery (0.4%). Patients submitted to direct SADI-S had an initial body mass index (BMI) of 49.6 kg/m2 in comparison of 56.2 kg/m2 in the two-step SADI-S (P < .001). The mean excess weight loss (EWL) at two years was higher in direct SADI-S (77.3 vs. 59.3%, P < .05). Rate of comorbidities resolution was 88.5% for diabetes, 73.0% for hypertension, 77.0% for dyslipidemia and 85.7% for sleep apnea, with no differences between both techniques. CONCLUSION: In medium term, SADI-S is a safe and effective technique that offers a satisfactory weight loss and remission of comorbidities. Patients submitted to two-step SADI-S had a higher initial BMI and presented a lower EWL than direct SADI-S.

Role of Gastrointestinal Hormones as a Predictive Factor for Long-Term Diabetes Remission: Randomized Trial Comparing Metabolic Gastric Bypass, Sleeve Gastrectomy, and Greater Curvature Plication.

PURPOSE: Long-term studies comparing the mechanisms of different bariatric techniques for T2DM remission are scarce. We aimed to compare type 2 diabetes (T2DM) remission after a gastric bypass with a 200-cm biliopancreatic limb (mRYGB), sleeve gastrectomy (SG), and greater curvature plication (GCP), and to assess if the initial secretion of gastrointestinal hormones may predict metabolic outcomes at 5 years. MATERIAL AND METHODS: Forty-five patients with mean BMI of 39.4(1.9)kg/m2 and T2DM with HbA1c of 7.7(1.9)% were randomized to mRYGB, SG, or GCP. Anthropometric and biochemical parameters, fasting concentrations of PYY, ghrelin, glucagon, and AUC of GLP-1 after SMT were determined prior to and at months 1 and 12 after surgery. At 5-year follow-up, anthropometrical and biochemical parameters were determined. RESULTS: Total weight loss percentage (TWL%) at year 1 and GLP-1 AUC at months 1 and 12 were higher in the mRYGB than in the SG and GCP. TWL% remained greater at 5 years in mRYGB group - 27.32 (7.8) vs. SG - 18.00 (10.6) and GCP - 14.83 (7.8), p = 0.001. At 5 years, complete T2DM remission was observed in 46.7% after mRYGB vs. 20.0% after SG and 6.6% after GCP, p < 0.001. In the multivariate analysis, shorter T2DM duration (OR 0.186), p = 0.008, and the GLP-1 AUC at 1 month (OR 7.229), p = 0.023, were prognostic factors for complete T2DM remission at 5-year follow-up. CONCLUSIONS: Long-term T2DM remission is mostly achieved with hypoabsortive techniques such as mRYGB. Increased secretion of GLP-1 after surgery and shorter disease duration were the main predictors of T2DM remission at 5 years.

Single Versus Double-Anastomosis Duodenal Switch: Single-Site Comparative Cohort Study in 440 Consecutive Patients.

PURPOSE: To study weight loss, comorbidity remission, complications, and nutritional deficits after duodenal switch (DS) and single-anastomosis DS with sleeve gastrectomy (SADI-S). MATERIAL AND METHODS: Retrospective review of patients submitted to DS or SADI-S for morbid obesity in a single university hospital. RESULTS: Four hundred forty patients underwent DS (n = 259) or SADI-S (n = 181). Mean preoperative body mass index (BMI) was 50.8 ± 6.4Kg/m2. Mean follow-up was 56.1 ± 37.2 months for DS and 27.2 ± 18.9 months for SADI-S. Global mean excess weight loss was 77.4% at 2 years similar for SADI-S and DS, and 72.1% at 10 years after DS. Although early complications were similar in SADI-S and DS (13.3% vs. 18.9%, p = n.s.), long-term complications and vitamin and micronutrient deficiencies were superior after DS. Rate of comorbidities remission was 85.2% for diabetes, 63.9% for hypertension, 77.6% for dyslipidemia, and 82.1% for sleep apnea, with no differences between both techniques. In patients with initial BMI > 55 kg/m2 (n = 91), DS achieved higher percentage of BMI < 35 kg/m2 (80% vs. 50%, p = 0.025) and higher rate of diabetes remission (100% vs. 75%, p = 0050). CONCLUSIONS: DS and SADI-S showed similar weight loss and comorbidity remission rates at 2 years. In patients with initial BMI > 55 kg/m2, DS obtained better BMI control at 2 years and better diabetes remission, but more long-term complications and supplementation needs.

Análisis de los criterios del profesional de Enfermería sobre la aplicación de los dispositivos de ostomía en cada momento del proceso asistencial / Analysis of the criteria by Nursing professionals regarding the application of ostomy devices at each moment of the care process

Objetivo: analizar la opinión y los criterios de los profesionales de Enfermería sobre la aplicación de los dispositivos de ostomía en cada momento del proceso asistencial teniendo en cuenta las características de la ostomía y del paciente. Método: estudio descriptivo transversal multicéntrico a partir de una encuesta nacional realizada a profesionales de Enfermería implicados en el cuidado a pacientes ostomizados. Resultados: a pesar de la disponibilidad de todo tipo de dispositivos de ostomías en la mayoría de los centros, a partir del ingreso en hospitalización, se instruye al paciente habitualmente en el manejo de dispositivos de dos piezas, lo que explicaría su mayor frecuencia de uso. Discusión y conclusiones: se han encontrado exposiciones de casos clínicos o investigaciones promovidas por la industria en los que no se justifica el uso de los dispositivos empleados, sino las características de estos mismos. Realizar una encuesta de ámbito nacional ofrece una visión global de los criterios que siguen los profesionales de Enfermería en el cuidado y manejo del paciente ostomizado y en la elección y/o el cambio de dispositivo de ostomía.(AU)

Objective: to analyse the opinion and criteria by Nursing professionals regarding the application of ostomy devices at each moment of the care process, considering the characteristics of the ostomy and the patient. Method: a multicentre cross-sectional descriptive study based on a national survey conducted on Nursing professionals involved in care for ostomized patients. Results: regardless of the availability of all type of devices in most centres, patients are usually trained from their admission to hospital in the use of two-piece devices, which would explain their higher frequency of use. Discussion and conclusions: there have been clinical case reports or research studies promoted by the industry with the characteristics of the devices but no justification for their use. A nationwide survey offers an overall view of the criteria followed by Nursing professionals for the care and management of ostomized patients and their choice and/or replacement of ostomy devices.(AU)

Salud oral y neoplasia gastrointestinal. Revisión narrativa / Oral health and gastrointestinal neoplasia: Narrative review

La cavidad oral constituye la puerta de entrada al complejo sistema digestivo, por lo que el conocimiento de los mecanismos que los vinculan es de vital importancia. En los últimos años la patología dental y oral ha sido analizada como potencial factor de riesgo de enfermedades vinculadas al estilo de vida y, por tanto, se está considerando como una posible interesante vía de prevención. Realizamos una revisión narrativa con búsqueda bibliográfica exhaustiva en las bases de datos MEDLINE y SCOPUS, incluyendo artículos internacionales que relacionan la salud oral con neoplasias del tracto digestivo, publicados entre 2015 y 2020. El objetivo de esta revisión es analizar la evidencia existente sobre la potencial asociación entre salud bucodental y procesos carcinogénicos del tracto gastrointestinal, proporcionando una posible futura vía de prevención a nivel odontológico. Como objetivo secundario, se fomenta concienciar sobre la importancia de la salud oral como nuevo paradigma y variable de estudio en el ámbito de la investigación médico-sanitaria. (AU)
