Venous resection in pancreatic oncologic surgery: Different techniques for different situations

INTRODUCTION

To report the clinical results of patients with malignant pancreatic lesions who underwent oncological surgery with vascular resection. The type of intervention performed, types of vascular reconstruction, the pathological anatomy results, postoperative morbidity and mortality, and survival at 3 and 5 years were analyzed.

METHODS

Retrospective, cross-sectional and comparative analysis. We include 41 patients with malignant pancreatic lesions who underwent surgery with vascular resection due to vascular involvement, from 2013 to 2021.

RESULTS

The most performed surgery was pancreaticoduodenectomy (Whipple procedure) using median laparotomy, in 35 out of the 41 patients (85%). One of the cases in the series was performed laparoscopically. Type 1 reconstruction (simple suture) was performed in 11 (27%) patients, type 2 in 4 (10%) cases, type 3 (end-to-end) in 23 (56%) cases, and type 4 reconstruction by autologous graft in 3 (7%) cases. The mean length of the resected venous segment was 21 (11-46) mm, and mean surgical time was 290 (220-360) minutes. 90% (37/41) were pancreatic adenocarcinoma. 83% were considered R0, and there was involvement in the resected vascular section in 41% of the cases. Four patients had Clavien Dindo morbidity >3, and there were no cases of postoperative mortality. Survival at 3 years was 48% and at 5 years 20%.

CONCLUSIONS

The aggressive surgical treatment with venous resection in pancreatic malignant lesions to ensure R0 and its vascular reconstruction is a feasible technique, with an acceptable morbid-mortality rate and overall survival.

Perioperative management of non-deferrable oncologic surgeries during COVID-19 pandemic in Madrid, Spain. Is it safe?

INTRODUCTION

Surgical treatment during COVID-19 pandemic is controversial. Currently, most clinical guidelines advise to defer surgical patients during the COVID-19 pandemic, although the supporting data is sparse. We assumed that a COVID-19-free hospital, on the back of strong isolation measures and targeted screening, could reduce complications and enable us to continue treating high-risk patients.

METHODS

Prospective study with retrospective analysis of 355 patients who had undergone nondeferrable oncological surgery between March 16th, 2020, and April 14th, 2020, at our institution. The aim of the study was to assess the hospital restructuring and surgical protocols to be able to safely handle non-deferrable surgeries during the first wave of the COVID-19 pandemic. We implemented structural changes and an updated surgical-anesthetic protocol in order to isolate COVID-19 patients from other surgical patients. Comprehensive targeted screening for COVID-19 patients was made. PCR tests were requested for suspected COVID-19 patients. We analyzed mortality and complications related to both surgery and COVID-19 during hospital admission and also 15 and 30 days after surgery. We compared it with a sample of similar patients in the pre-pandemic period.

RESULTS

Of the 355 patients enrolled in our study, 21 were removed due to COVID-19 infection, leaving a total of 334 patients in our final analysis. Post-operative complications were found in 37 patients (11.07%). Two patients died after surgery (0.6%). At the end of the study, COVID-19-related adverse outcomes were detected in six patients (1.79%). When comparing the complications of our original sample with the complications that occurred in the pre-COVID era, we found no statistically significant differences.

CONCLUSIONS

Our results show that the surgical treatment of oncologic patients during the COVID-19 pandemic is safe, as long as the hospital performs surgeries under strict isolation measures and a robust screening method. It is necessary to select COVID-19 free hospitals for this matter in this and future pandemics.

Recommendations on intervention for hepatobiliary oncological surgery during the COVID-19 pandemic

The SARS-CoV-2 (COVID-19) pandemic requires an analysis in the field of oncological surgery, both on the risk of infection, with very relevant clinical consequences, and on the need to generate plans to minimize the impact on possible restrictions on health resources. The AEC is making a proposal for the management of patients with hepatopancreatobiliary (HPB) malignancies in the different pandemic scenarios in order to offer the maximum benefit to patients, minimising the risks of COVID-19 infection, and optimising the healthcare resources available at any time. This requires the coordination of the different treatment options between the departments involved in the management of these patients: medical oncology, radiotherapy oncology, surgery, anaesthesia, radiology, endoscopy department and intensive care. The goal is offer effective treatments, adapted to the available resources, without compromising patients and healthcare professionals safety.

Perioperative anesthetic management of patients with malignant pleural mesothelioma undergoing cytoreductive surgery and intraoperative chemotherapy

INTRODUCTION

Cytoreductive surgery with hyperthermic intraoperative chemotherapy (HITHOC) is a therapeutic option for treatment of malignant pleural mesothelioma. Anesthetic management might be challenging.

PATIENTS AND METHODS

A descriptive analysis of a case series is presented. Seven patients with malignant pleural mesothelioma diagnostic undergoing HITHOC surgery were studied. Combined general and epidural anesthesia were administered. An intensive hemodynamic monitorization was implemented. Data regarding perioperative course was analyzed.

RESULTS

Between May 2015 and October 2018 7patients underwent HITHOC procedure. Blood transfusions were administered in all patients, and 5of the 7patients required vasoactive drug administration. Extubation at the end of the procedure was able in 6of the 7patients. The median length of stay in ICU was 4 days, and 29 days for the whole hospitalary stay. No significant postoperative pain was observed.

CONCLUSIONS

HITHOC surgery is a complex procedure in which several hemodynamic changes occur. An intensive intraoperative monitorization was useful for controlling complications.

Current situation of soft tissue sarcomas: Registry of a Latin American cancer institute

INTRODUCTION

Soft tissue sarcomas (SFT) are a group of rare and heterogeneous neoplasms (representing less than 1% of cancer in adults and 15% in pediatric patients), for which there is no updated records in the Latin American population. This study aims to describe the current situation of patients treated at a cancer institute in Latin America.

METHODS

We obtained records from 250 patients with a diagnosis of SFT, treated at the National Institute of Neoplastic Diseases of Peru (INEN) during the period 2009-2013, with a mean follow-up of 62 months. The following data were recorded: epidemiological, clinical, treatment and follow-up. The analysis of global survival was done with the Cox proportional hazards model.

RESULTS

SFT showed a greater frequency in males (60.8%), with a peak incidence after 50 years of age (69.6%). Tumor location was predominantly in the lower extremities (64.4%), and the most frequent histologic subtypes were: undifferentiated pleomorphic sarcoma (34%) and liposarcomas (25.6%); clinical stage iii was the most frequent (30.8%). The 5-year overall survival rate was 63.9%, while the statistical analysis found a significant association between global survival and the variables: age (>50 years), tumor size (>5cm), depth (subfascial), histologic grade (G3), local and distant recurrence, showing shorter survival times in these groups.

CONCLUSIONS

This study has clarified the epidemiology, treatment and prognosis, as well as the variables that have an impact on the survival of the Latin American patients with SFT studied.

[Preoperative management of anemia in oncologic surgery]

Preoperative anemia in patients with cancer is highly prevalent, is associated with increased perioperative morbidity and is a risk factor for transfusion. There is evidence that patients who undergo transfusions have higher morbidity, increased cancer recurrence and poorer survival. The pathophysiology of anemia is multifactorial, with an inflammatory component to which chronic blood loss and nutritional deficiencies can be associated. Therefore, preoperative anemia in patients with cancer should be treated appropriately, given that there is sufficient time in the preoperative period. Of the currently available options, parenteral iron is an effective alternative, especially for those types of cancer that have an associated hemorrhagic component.
