Delayed gastric emptying after pancreatoduodenectomy: an analysis of risk factors.

BACKGROUND: Delayed gastric emptying (DGE) is a frequent complication after pancreatoduodenectomy. Preoperative factors are limited and controversial. This study aims to identify associated factors related to this complication in the Colombian population. METHODS: A retrospective review of a prospectively collected database was conducted. All patients over 18 years of age who underwent pancreaticoduodenectomy were included. Associations with DGE syndrome were evaluated with logistic regression analysis, Odds ratio, and b-coefficient were provided when appropriate. RESULTS: 205 patients were included. Male patients constituted 54.15% (n = 111). 53 patients (25.85%) were diagnosed with DGE syndrome. Smoking habit (OR 17.58 p 0.00 95% CI 7.62-40.51), hydromorphone use > 0.6 mg/daily (OR 11.04 p 0.03 95% CI 1.26-96.66), bilirubin levels > 6 mg/dL (OR 2.51 p 0.02 95% CI 1.12-5.61), and pancreatic fistula type B (OR 2.72 p 0.02 CI 1.74-10.00). DISCUSSION: Smoking history, opioid use (hydromorphone > 0.6 mg/Daily), type B pancreatic fistula, and bilirubin levels > 6 mg/dL should be considered as risk factors for DGE.

Primary hepatic angiosarcoma: a systematic review.

Background: Hepatic angiosarcoma is a rare type of tumour. In adults, the diagnosis remains challenging as the clinical manifestations are generally nonspecific and are usually made too late when complications or metastases are already present, associated with a poor prognosis. Due to the lack of agreement regarding the optimal treatment approach, a comprehensive analysis of the evidence in the literature on the surgical and survival outcomes in terms of disease-free survival time (DFS) and overall survival (OS) for patients treated for primary hepatic angiosarcoma is needed. Study design: A systematic review of articles published in Pubmed, EMBASE, and Scopus, from 2000 to 2023 with the search terms hepatic angiosarcoma and liver resection or hepatectomy. Pooled individual data concerning the prognosis following various therapies was analyzed. Results: A total of 15 articles involving 886 patients were eligible for inclusion. The male population represents 66.2% (n=586) of the population, with a median age of 57 years (41-66). The median survival rate was 7 months. The median OS after surgical resection was 17.18 months (SD 12.6) vs. 3.72 months (SD 4.6) for patients treated without a surgical approach. The median DFS was 15.2 months (SD 11). Conclusion: Primary liver angiosarcoma remains a surgical challenge with a poor prognosis even with complete surgical resection and adjuvant therapy. Surgical management shows increased overall survival in comparison with non-surgical management. Early diagnosis could change the natural history of the disease. The literature available is scarce, and further studies are required to create standardized diagnostic and treatment protocols.

An unusual case of small bowel volvulus due to pneumatosis cystoides intestinalis: Case report and literature review.

INTRODUCTION AND IMPORTANCE: Pneumatosis cystoides intestinalis (PCI) is an uncommon condition characterized by intramural gas accumulation in the intestinal submucosa. Idiopathic or secondary is presented with non-specific clinical signs; in some cases, diagnosis is incidental. Its acute presentation is uncommon, and surgical management could be performed in selected cases. CASE PRESENTATION: We present the case of an 85-year-old woman with 3 days of abdominal pain, 6 months of weight loss, and abdominal distension after meals. Abdominal computed tomography evidenced PCI at the small intestine with changes due to intestinal ischemia and internal mesenteric hernia. Intestinal resection and lateral-lateral mechanical anastomosis were performed with no complications after 90 days of follow-up. CLINICAL DISCUSSION: PCI is an infrequent and benign condition; pathophysiology is, to date, poorly understood. Idiopathic or secondary to other gastrointestinal pathologies are described. The final diagnosis is performed with histopathological analysis. Nevertheless, in some cases, the benign nature could be presented as an acute abdomen, and surgical management should be in the physician's armamentarium. CONCLUSION: PCI is an uncommon and benign entity. Nevertheless, in some cases, it could be presented as an acute abdomen. The surgical approach is appropriate, safe, and feasible.

Negative Pressure Wound Therapy After Intestinal Anastomosis: A Risk Factor Analysis for Dehiscence.

INTRODUCTION: Negative pressure wound therapy (NPWT) is part of the temporary abdominal closure in the treatment of patients with traumatic, inflammatory, or vascular disease. However, the use of NPWT when performing an intestinal anastomosis has been controversial. This study aimed to describe the patients managed with NPWT therapy and identify the risk factors for anastomotic dehiscence when intestinal anastomosis was performed. METHODS: A single-center cohort study with prospectively collected databases was performed. Patients who required NPWT therapy from January 2014 to December 2018 were included. Patients were stratified according to the performance of intestinal anastomosis and according to the presence of dehiscence. Bivariate and multivariate analyses were performed for anastomotic dehiscence and mortality. RESULTS: A total of 97 patients were included. Median age was 52 y old [interquartile range 24.5-70]. Male patients corresponded to 75.6% (n = 34) of the population. Delayed fascial closure was performed in 80% (n = 36). The risk of anastomotic dehiscence was higher in females (odds ratio (OR) 11.52 [confidence interval (CI) 1.29-97.85], P = 0.030), delayed fascial closure (OR 18.18 [CI 2.02-163.5], P = 0.010) and use of vasopressors (OR 12.04 [CI 1.22-118.47], P = 0.033). NPWT pressures >110 mmHg were evidenced in the dehiscence group with statistically significant value (OR 1.2 [0.99-2.26] p 0.04) CONCLUSIONS: There is still controversy in the use of NPWT when performing intestinal anastomosis. According to our data, the risk of dehiscence is higher in females, delayed fascial closure, use of vasopressors, and NPWT pressures >110 MMHG.

Case report: Endovascular stent-graft repair of aortic penetrating trauma, literature review, and case report.

Penetrating aortic injuries are infrequent. Its incidence is unknown because most patients die of hemorrhage even before they receive adequate treatment. Aortic wounds generally require conventional thoracotomy/laparotomy repair and are related to high mortality rates. Recently with the advent of endovascular techniques, most authors prefer endovascular management when feasible due to better (still poor) outcomes. The short- and mid-term results of immediate endovascular repair of traumatic aortic injuries are promising, especially when compared with open surgical treatment, indicating that endovascular therapy is preferable in patients with multi-trauma and traumatic ruptures of the thoracic aorta. Here we present the diagnosis and treatment of a 30 years-old male patient with multiple traumatic stab wounds, including anterior aortic laceration with a grade II aortic lesion successfully managed with an endovascular stent graft.

Endovascular approach of hepatic artery pseudoaneurysm after Whipple procedure: Case report and literature review.

INTRODUCTION AND IMPORTANCE: Pseudoaneurysms after pancreatoduodenectomy are an uncommon complication, but they are associated with life-threatening outcomes in up to 50 % due to the development of postoperative bleeding. They usually result as a consequence of local inflammatory processes, such as pancreatic fistula or intra-abdominal collections. The cornerstones of treatment are thus intraoperative management and early identification of the complication. CASE PRESENTATION: We present a 62-year-old female patient in postoperative pancreatoduodenectomy due to a periampullary tumor, that presented upper gastrointestinal bleeding which required multiple transfusions. During hospitalization, the patient presented a refractory hypovolemic shock to conservative measures. It was documented intra-abdominal hemorrhage due to hepatic artery pseudoaneurysm that required endovascular management with common hepatic artery embolization, with successful bleeding control. CLINICAL DISCUSSION: Pseudoaneurysms are the result of tissue damage after surgery. The usual clinical presentation is upper gastrointestinal bleeding unresponsive to conservative treatment that results in hemodynamic instability due to hypovolemic shock. Prevention is currently based on preoperative and intraoperative measures such as nutritional repletion, vessel protection, adequate hemostasis, and prevention and treatment of pancreatic leak and abdominal infection. Once documented, treatment can be endovascular or surgical. CONCLUSION: The formation of pseudoaneurysms after pancreaticoduodenectomy is an uncommon and challenging complication. Early diagnosis, risk factor detection and a combined multidisciplinary approach lead to better outcomes, avoiding open surgical procedures that can increase morbidity and mortality rates.

Valentino's syndrome: Simulation of acute appendicitis in the context of peptic ulcer perforation. Case report and literature review.

INTRODUCTION AND IMPORTANCE: Abdominal pain (AP) is one of the main reasons for consultation in the emergency department worldwide. The causes of AP are gathered in a broad group of pathologies whose incidence and prevalence vary according to various factors. The great importance of an adequate approach to AP lies in ruling out or confirming the presence of acute abdomen that requires emergency surgical management. Valentino's Syndrome (VS) simulates the clinical manifestations of acute appendicitis whose origin is the perforation of a peptic ulcer. This is an infrequent entity, with very few reports in the literature, this being the second case reported in Colombia. CASE PRESENTATION: We present a case of VS in a 59-year-old male patient who was admitted to the emergency department with 3 days of pain in the right iliac fossa that met the diagnostic criteria for acute appendicitis. However, upon surgical exploration, it was determined that the cause was secondary to peptic ulcer perforation (PPU). DISCUSSION: PPU is one of the most infrequent complications of the disease, occurring in close to 10 % of cases, and is considered a surgical emergency. Minimally invasive surgery provides a significant benefit over open surgery, outcomes that directly lead to decreased healthcare costs and increased patient satisfaction. CONCLUSION: PPU represents a diagnostic challenge due to the variability of the symptoms and clinical features. Laparoscopic approach fulfills diagnostic and therapeutic roles with lesser morbidity and mortality rates, which is why it should be standardized. Malignancy should be ruled out in all cases.

Aortoesophageal fistulae following TEVAR: Case report and literature review.

INTRODUCTION: Aortoesophageal fistulae are an uncommon pathology, primarily due to the aortic pathology in more than 50 % of the cases, followed by foreign body ingestion, and advanced malignancies. Recently it is recognized after surgical management of thoracic aortic pathologies either open or endovascular, with increased rates of morbidity and mortality. PRESENTATION OF THE CASE: We present a 62-year-old male patient with a previous history of thoracic endovascular aortic repair, who enters the emergency room with gastrointestinal bleeding and clinical signs of infection. Positive blood cultures, and tomographic signs include prosthetic gas, with endoscopic findings of aortoesophageal fistulae. Aggressive surgical management was performed including esophageal resection and gastrointestinal exclusion. Bleeding control was reached in the early postoperative period, nevertheless despite multidisciplinary management, the patient died 8 days after surgery. CLINICAL DISCUSSION: Aortoesophageal fistulae, remains to be an uncommon complication either of thoracic aortic aneurysm or after endovascular treatment of aortic aneurysm; with high rates of morbidity and mortality, should be suspected in every case with upper gastrointestinal bleeding in the context of a patient with aortic disease. Non-surgical management should be avoided due to the high risk of complications and mortality, aggressive management needs to be considered in each case according to clinical condition of the patient. CONCLUSION: Aortoesophageal fistulae remain an uncommon complication after TEVAR, with increased mortality and morbidity rates after complete treatment. Conservative management should be avoided to achieve bleeding control and prevent the extension of the infection.

Giant Hydatid Cyst with Diaphragmatic, Pericardial, and Hepatic Involvement: Use of Extracorporeal Circulation for Major Liver Resection: A Case Report and Literature Review.

BACKGROUND Echinococcosis is a zoonosis caused by the echinococcus microorganism, a parasite with 6 described species in the literature, the main one in humans being Echinococcus granulosus. Transmission is via the fecal-oral route, with main hepatopulmonary involvement but with high risk of dissemination. Diagnosis is often incidental and patients present a wide range of non-specific symptoms, closely related to localization, size, and quantity of cysts. The latent risk of the infection is septic shock secondary to intraperitoneal rupture, which increases the risk of mortality. The criterion standard of management involves anthelmintic therapy and radical surgical management. CASE REPORT We present the case of a man in the third decade of life from a rural area of Colombia, presenting abdominal pain and febrile peaks for 2 months. Imaging studies showed a cystic lesion with thoracic and hepatic involvement. He was treated in 2 surgical stages, the first achieving partial resection of the cyst involving lung, diaphragm, and rib cage, and the second with extracorporeal circulation assistance due to infiltration of the retrohepatic vena cava, achieving radical resection of the disease. CONCLUSIONS Echinococcosis is a condition endemic to rural areas, with wide geographical distribution. Given the slow growth, it is mostly asymptomatic, which causes diagnostic and therapeutic challenges involving high rates of complications and mortality. An individualized surgical and medical approach is recommended. Extracorporeal circulation assistance helps achieve hemodynamic stability in patients with cardiac or great vessel involvement. To the best of our knowledge, this is the first report of extracorporeal circulation assistance for large hepatic-diaphragmatic and pericardial cyst resection.

The Clinical Impact of Thoracic Endovascular Aortic Repair in the Management of Thoracic Aortic Diseases.

PURPOSE: Thoracic endovascular aortic repair (TEVAR) has been described to be superior to an open surgical approach, and previous studies have found superiority in TEVAR by reducing overall morbidity and mortality rates. This study aimed to describe the outcomes of TEVAR for patients with thoracic aortic disease at a high complexity. MATERIALS AND METHODS: Descriptive study, developed by a retrospective review of a prospectively collected database. Patients aged above 18 years who underwent TEVAR between 2012 and 2022 were included. Patient demographics, perioperative data, surgical outcomes, morbidity, and mortality were described. Statistical and multivariate analyses were made. Statistical significance was reached when p values were <0.05. RESULTS: A total of 66 patients were included. Male patients were 60.61% and the mean age was 69.24 years. Associated aortic diseases were aneurysms (68.18%), ulcer-related (4.55%), intramural-related hematoma (7.58%), trauma-related pathology (1.52%), and aortic dissection (30.30%). The mean hospital stay was 18.10 days, and intensive care unit was required for 98.48%. At 30 days, the mortality rate was 10.61% and the reintervention rate was 21.21%. Increased intraoperative blood loss (p=0.001) and male sex (p=0.04) showed statistical relationship with mortality. Underweight patients have 6.7 and 11.4 times more risk of complications and endoleak compared with higher body mass index values (p=0.04, 95% confidence interval [CI]=0.82-7.21) and (p=0.02, 95% CI=1.31-12.57), respectively. CONCLUSION: Thoracic endovascular aortic repair seems to be a feasible option for patients with thoracic aortic pathologies, with adequate rates of mortality and morbidity. Underweight patients seem to have an increased risk of overall morbidity and increased risk for endoleak. Further prospective studies are needed to prove our results. CLINICAL IMPACT: Obesity and BMI are widely studied in the surgical literature. According to our study, there is a paradox regarding the outcomes of patients treated with TEVAR in terms of postoperative complications and mortality related to the body mass index. And shouldn't be considered as a high-risk feature in terms of postoperative morbidity and mortality in this procedure.

Management of pneumothorax with 8.3-French Pigtail Catheter: description of the ultrasound-guided technique and case series.

Spontaneous and traumatic pneumothorax are most often treated with chest tube (CT) thoracostomy. However, it appears that small-bore drainage systems have similar success rates with lower complications, pain, and discomfort for the patient. We present the description of the ultrasound-guided technique for pneumothorax drainage with an 8.3-French pigtail catheter (PC) in a case series of 10 patients.

Laparoscopic and open gastrectomy for locally advanced gastric cancer: a retrospective analysis in Colombia.

INTRODUCTION: Radical gastrectomy has traditionally been the pillar treatment with curative intent for malignant tumors of the stomach. The safety of the laparoscopic approach for advanced gastric cancer (AGC) is still under debate. In our institution, laparoscopic gastrectomy is the most performed approach. OBJECTIVE: Our aim is to describe the experience of a high-volume center in the treatment of AGC in Colombia and to analyze the short-term results and the overall survival rate at 1, 3, and 5 years comparing the open and laparoscopic approaches. METHODS: A cross-sectional retrospective study of patients who underwent gastrectomy for advanced gastric cancer by open or laparoscopic approaches were performed. A Will-Coxon Mann Whitney test was performed in terms of lymph node status and surgical approach. Survival analysis was performed using the Kaplan-Meier method for overall survival at 1, 3, and 5 years. An initial log-rank test was performed to test the relationships between the operative variables and overall survival, the statistical value was accepted if p < 0.20. Data with an initial statistical relationship in the log-rank test were included in a secondary analysis using multivariate Cox proportional regression, variables with a value of p < 0.05 were considered statistically significant. RESULTS: 310 patients met the inclusion criteria. 89% underwent laparoscopic gastrectomy and 10.9% open gastrectomy. The resection margins were negative at 93.5% and the In terms of lymph node dissection, the median lymph nodes extracted was 20 (12;37), with statistically significant differences between the approaches in favor of the laparoscopic approach (Median 21 vs 12; z = - 2.19, p = 0.02). The survival rate was at 1, 3, and 5 years of 84.04%, 66.9%, and 65.47% respectively. The presence of complications and the ICU requirement have a negative impact on survival at 1 year (p 0.00). CONCLUSION: A laparoscopic approach is safe with acceptable morbidity and mortality rates for treating gastric cancer. D2 Lymphadenectomy could be performed successfully in a laparoscopic approach in a high-volume center and a properly standardized technique. Major postoperative morbidity with intensive care unit requirement seems to influence overall survival rates.

Percutaneous closure of subclavian iatrogenic injuries after central venous catheterization: a Latin American experience.

Introduction: Arterial injuries following central venous catheterization (CVC) range between 0.1%-2.7%. The open surgical approach could be related to increased rates of morbidity and mortality. Vascular closure devices (VCD) are often used for the management of these patients with a success rate of up to 80%. Objectives: Describe our experience in managing arterial vascular injuries following central venous catheterization with Perclose ProGlide (Abbott Vascular IncSanta Clara, CA, USA). Methods: A retrospective review of all patients over 18 years old who underwent percutaneous closure of arterial injuries following central venous catheterization in our center between January 2018 and May 2023 was included and reported with a 90-day follow-up. Results: 3 Patients were included, in all cases, access to the CVC were right with a subclavian artery injury. Ultrasound and fluoroscopy guide was used in all cases. For the 3 cases, a percutaneous technique using Perclose ProGlide (Abbott Vascular IncSanta Clara, CA, USA) was performed. With a 100% success rate, and no complications evidenced after 90 days of follow-up. Conclusion: Inadvertent arterial catheterization it's a non-negligible complication after CVC placement. VCD could be considered a safe and feasible approach for the management of these traumatic injuries.

Meckel's diverticulum: analysis of 27 cases in an adult population.

Background: Meckel's diverticulum is a rare congenital pathology among newborns. Nevertheless, it is an uncommon abdominal pathology in the adult population. Therefore, we aim to provide a detailed account of our surgical approach in treating 27 cases of Meckel's diverticulum. Methods: This study is a cross-sectional analysis that utilized a database with prospectively collected data from 2004 to 2022. All patients under the age of 18 were excluded from the population. We described the population's demographic characteristics, symptoms, anatomopathological study, surgical technique, complications, morbidity, and mortality. A subgroup analysis was performed between the symptomatic and asymptomatic patients. Results: A total of 27 patients who underwent surgical resection for a posteriorly diagnosed Meckel's diverticulum were included. The male population accounted for 81.4% (n = 22) of the sample size. The symptomatic group consisted of 18 male and four female patients. Abdominal pain was the predominant symptom in 85% of the patients. Out of the 22 symptomatic patients, only 9% had a positive perioperative diagnosis of Meckel's diverticulum. All 27 patients with diverticulum diagnosis received the resection through diverticulectomy (n = 6), small bowel resection with end-to-end anastomosis (n = 6), and small bowel resection with lateral to lateral anastomosis (n = 15). The mean distance between the diverticulum and the ileocecal valve was 63.4 cm. The symptomatic group had an average diverticulum length of 3.54 cm, with an average base width of 2.47 cm. In the other group, the values were 2.75 and 1.61 cm. The average length of hospital stay in the symptomatic group was 7.3 days. Conclusions: Meckel's diverticulum is a rare pathology in the adult population. Its presentation varies from asymptomatic to symptomatic patients, and surgery is the cornerstone treatment for this pathology.

Outcomes after Frey's procedure for chronic pancreatitis: a 8-year single-center experience in Colombia.

BACKGROUND: Chronic pancreatitis is an inflammatory disease characterized by irreversible morphological changes due to chronic pancreatic fibrosis. The treatment goals are to relieve pain, preserve function, and prevent further pathological consequences. Endoscopic treatment, surgery, or both are options for untreatable pain or suspected malignancy. Frey procedure is a reasonable surgical intervention because of its hybrid character, combining resection and drainage. Unfortunately, there is limited information about the outcomes of this procedure in Latin America, and few cases described in Colombia. This study aims to describe the experience of a pancreatic surgery reference center in the management of patients undergoing Frey's surgery for chronic pancreatitis. METHODS: A retrospective review of a prospectively collected database of patients who underwent a Frey procedure due to chronic pancreatitis between January 2014 to February 2022 in a hospital in Bogotá, Colombia, was made. A demographic, clinical, and postoperative outcome description was performed. Mann-Whitney Willcoxon test was performed between operative variables and long-term outcomes. RESULTS: Eighteen patients met the inclusion criteria. 55.5% of patients were male. Chronic pancreatitis etiology in most cases (83.3% n = 15) was idiopathic. The median duration of symptoms and chronic pancreatitis diagnosis before surgery was 6.15 months (IQR 5;97). Overall morbidity was 38.88%. One patient died at 30 days of follow-up. The median follow-up time was 42.5 (IQR 19;65 months). The median pain reduction was 3 points according to the visual analog score. Six patients were diagnosed with malignant conditions after surgery (mean 27.8 ± 7.5 months). Wirsung's duct size was statistically related with malignancy presentation after Frey's procedure (Z = 2.54; P = 0.01). CONCLUSION: According to our data, Frey's procedure remains safe and feasible, with acceptable outcomes in terms of pain relief and pancreatic function. The study confirms the importance of a longstanding follow-up due to an inherent risk of pancreatic malignancy. Our data suggest that pancreatic duct size could be related with the malignancy diagnosis after Frey's procedure; however, further prospective studies with a larger sample size would be helpful to confirm these results.

Succoring the challenging acute mesenteric ischemia: Feasibility of lactate dehydrogenase for evaluation of intestinal necrosis extension and mortality.

Background: Acute mesenteric ischemia is a lethal challenging pathology for surgeons in the emergency department due to its ambiguous clinical presentation and lack of early diagnostic markers. Serum lactate is considered a relevant biomarker in terms of bowel necrosis length and mortality prediction. Nevertheless, its association has been poorly studied. Hence, we evaluated the relation between serum lactate admission levels, bowel necrosis extension, and mortality in patients with acute mesenteric ischemia. Methods: A Retrospective cross-sectional study with a prospective database was conducted, including patients over 18 years old with mesenteric ischemia that required surgical management between January 2012 and December 2018. We describe the association between serum lactate admission levels with bowel necrosis length and mortality in patients with acute mesenteric ischemia. Results: 74 patients presented with acute mesenteric ischemia, 44 males and 30 females. Mean age was 73.5 ± 10.7 years old. Significant association between serum lactate admission levels and mortality was found (ROC cut-value of 3.8 mmol/l, 81.0% sensibility and 76% specificity, LR+3.41 (95%CI 1.57, 7.40), LR- 0.25 (95%CI 0.13-0.45))(P.001). Nonetheless no statistically significant association was found between serum lactate admission levels and bowel necrosis length (ρ = 0.195,95%CI -0.046, -0.436, P > .99). As post hoc analysis, a classification and regression tree on mortality was fitted. Conclusions: Early diagnosis, prognosis and management of mesenteric ischemia is vital given its high morbidity and mortality. Serum lactate admission levels can be considered as a useful prognostic tool in terms of mortality in patients with acute mesenteric ischemia.

Hemosuccus pancreaticus as an unusual cause of upper gastrointestinal bleeding: Case report and literature review.

BACKGROUND: Hemosuccus pancreaticus is a rare cause of upper gastrointestinal bleeding (1/1500) and represents the loss of blood through the main pancreatic duct and its exteriorization through the major duodenal papilla. It can lead to massive bleeding, which is potentially life-threatening. This condition most commonly follows pseudoaneurysm formation due to acute or chronic pancreatitis. As a result of its infrequency, it is difficult to diagnose, and the mortality rate remains high. To our knowledge, this is the first case report on the Latin-American population. CASE PRESENTATION: A 70-year-old male patient presented with diffuse severe abdominal pain associated with melaena. Angiotomography was performed, ruling out mesenteric ischemia, with evidence of pancreatic head tumor with liver metastases. Sandblom's triad was present and the diagnosis of hemosuccus pancreaticus was confirmed. Multiple arteriograms were performed, with pseudoaneurysm of gastroduodenal artery findings. Therefore, endovascular coil embolization was performed in two opportunities to control the bleeding. CONCLUSION: Upper gastrointestinal bleeding is a clinical challenge for the surgeon and emergency medicine. It's a complex entity with high mortality that should be suspected in patients with acute or chronic pancreatitis and periampullary tumors with non-established sources of bleeding. Clinically manifested by Sandblom's triad. Its diagnosis gold standard is arteriography plus embolization which is also therapeutic. Surgery is related to higher mortality and reserved for specific situations.

Porto-biliary fistula as an uncommon cause of haemobilia: A case report and literature review.

BACKGROUND: Haemobilia is a rare cause of gastrointestinal bleeding. It can be related to iatrogenic injuries, inflammatory diseases, and, more recently, postoperative, or post-procedure complications. Porto-biliary fistula is an uncommon case of haemobilia and has been related to iatrogenic injury or chronic inflammatory processes. To date, less than 30 cases of Porto-biliary fistula have been reported. CASE PRESENTATION: We present a 53 years-old woman with a history of biliary obstruction due to a choledochal cyst that required hepaticojejunostomy with evidence of anastomotic stricture. A percutaneous transhepatic biliary drainage (PTBD) was performed, with 3 failed attempts of percutaneous dilatation. A new hepaticojejunostomy was completed, however, 45 days later the patient presented to the emergency room with haemobilia and secondary hemodynamic instability. An emergency damage control laparotomy was performed, achieving bleeding control. In the second procedure, there is evidence of an ulcerative injury of the biliary tract secondary to a Porto-biliary fistula. CONCLUSION: Porto-biliary fistula is an entity that cannot be ruled out in cases of haemobilia, especially in cases with a history of bile duct surgical or percutaneous procedures. The prognosis is usually good if multidisciplinary management is performed, and the source of the bleeding is identified early.

Postoperative outcomes of minimally invasive adrenalectomy: do body mass index and tumor size matter? A single-center experience.

BACKGROUND: Since Gagner performed the first laparoscopic adrenalectomy in 1992, laparoscopy has become the gold-standard procedure in the treatment of adrenal surgical diseases. A review of the literature indicates that the rate of intra- and postoperative complications are not negligible. This study aims to describe the single-center experience of adrenalectomies; and explore the associations between body mass index (BMI) and tumor volume in main postoperative outcomes. METHODS: Retrospective observational study with a prospective database in which we described patients who underwent adrenalectomy between January 2015 and December 2020. Operative time, intraoperative blood loss, conversion rate, complications, length of hospital stay, and comparison of the number of antihypertensive drugs used before and after surgery were analyzed. Analysis of BMI and tumor volume with postoperative outcomes such as anti-hypertensive change (AHC) in drug usage and pre-operative conditions were performed. RESULTS: Forty-five adrenalectomies were performed, and all of them were carried out laparoscopically. Four were performed as a robot-assisted laparoscopy approach. Nineteen were women and 26 were men. Mean age was 54.9 ± 13.8 years. Mean tumor volume was 95.698 mm3 (3.75-1010.87). Mean operative time was shorter in right tumors (2.64 ± 0.75 h) than in left tumors (3.33 ± 2.73 h). Pearson correlation was performed to assess the relationship between BMI and AHC showing a direct relationship between increased BMI and higher change in anti-hypertensive drug usage at postoperative period r(45) = 0.92, p > 0.05 CI 95%. Higher tumor volume showed a longer operative time, r(45) = 0.6 (p = 0.000 CI 95%). CONCLUSIONS: Obese patients could have an increased impact with surgery with an increased change in postoperative anti-hypertensive management. Tumor volume is associated with increased operative time and blood loss, our data suggest that it could be associated with increased rates of morbidity. However, further prospective studies with larger sample sizes are needed to validate our results.

Early versus delayed reconstruction for bile duct injury a multicenter retrospective analysis of a hepatopancreaticobiliary group.

Common bile duct injury is a severe complication. It is related to increased rates of morbidity and mortality. Early recognition and on-time diagnosis plus multidisciplinary management of this disease led by a hepatobiliary surgeon show fewer complications rate and best postoperative outcomes. However, no guidelines exist about the proper time of reconstruction. This study aims to describe the experience of a specialized Hepato-Pancreatic-Biliary (HPB) group and to analyze the outcomes regarding the time of bile duct injury (BDI) repair. A multicenter retrospective review of a prospective database was conducted. All the patients older than 18 years old that underwent common bile duct reconstruction between January 2014 and December 2021 were included. Analysis and description of preoperative characteristics and postoperative outcomes were performed. A reconstruction time-based group differentiation was made and analyzed. 44 patients underwent common bile duct reconstruction between January 2014 and December 2021. 56.82% of the patients were female. The mean age was 53.27 years ± 20.7 years. The most common injury was type E2 (29.55%). Hepaticojejunostomy was performed in 81.81% (of the patients. Delayed reconstruction (> 72 h) was performed in the majority of the cases (75.00%) due to delays in the referral centers or poor condition. No statistically significant difference regarding complications in early or delayed BDI reconstruction. The mortality rate was 2.7% (n = 1). 2-year follow-up bilioenteric stenosis was observed in 7 patients. Biloma showed a statistical relationship with complex bile duct injuries (p = 0.02). Bile duct injury is a severe and complex postoperative complication that increases morbidity and mortality rates in the short and long term in patients undergoing cholecystectomy. In our study, there were no statistical differences between the timing of bile duct reconstruction and the postoperative outcomes; we identified the presence of biloma as a statistically related factor associated with complex bile duct injury; however, further prospective or studies with an increased sample size are required to prove our results.
