RESUMEN

BACKGROUND: The first wave of coronavirus disease 2019 (COVID-19) pandemic in Spain lasted from middle March to the end of June 2020. Spanish population was subjected to lockdown periods and scheduled surgeries were discontinued or reduced during variable periods. In our centre, we managed patients previously and newly diagnosed with cancer. We established a strategy based on limiting perioperative social contacts, preoperative screening (symptoms and reverse transcription-polymerase chain reaction) and creating separated in-hospital COVID-19-free pathways for non-infected patients. We also adopted some practice modifications (surgery in different facilities, changes in staff and guidelines, using continuously changing personal protective equipment…), that supposed new inconveniences. AIM: To analyse cancer patients with a decision for surgery managed during the first wave, focalizing on outcomes and pandemic-related modifications. METHODS: We prospectively included adults with a confirmed diagnosis of colorectal, oesophago-gastric, liver-pancreatic or breast cancer with a decision for surgery, regardless of whether they ultimately underwent surgery. We analysed short-term outcomes [30-d postoperative morbimortality and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection] and outcomes after 3 years (adjuvant therapies, oncological events, death, SARS-CoV-2 infection and vaccination). We also investigated modifications to usual practice. RESULTS: From 96 included patients, seven didn't receive treatment that period and four never (3 due to COVID-19). Operated patients: 28 colon and 21 rectal cancers; laparoscopy 53.6%/90.0%, mortality 3.57%/0%, major complications 7.04%/25.00%, anastomotic leaks 0%/5.00%, 3-years disease-free survival (DFS) 82.14%/52.4% and overall survival (OS) 78.57%/76.2%. Six liver metastases and six pancreatic cancers: no mortality, one major complication, three grade A/B liver failures, one bile leak; 3-year DFS 0%/33.3% and OS 50.0%/33.3% (liver metastases/pancreatic carcinoma). 5 gastric and 2 oesophageal tumours: mortality 0%/50%, major complications 0%/100%, anastomotic leaks 0%/100%, 3-year DFS and OS 66.67% (gastric carcinoma) and 0% (oesophagus). Twenty breast cancer without deaths/major complications; 3-year OS 100% and DFS 85%. Nobody contracted SARS-CoV-2 postoperatively. COVID-19 pandemic-related changes: 78.2% treated in alternative buildings, 43.8% waited more than 4 weeks, two additional colostomies and fewer laparoscopies. CONCLUSION: Some patients lost curative-intent surgery due to COVID-19 pandemic. Despite practice modifications and 43.8% delays higher than 4 weeks, surgery was resumed with minimal changes without impacting outcomes. Clean pathways are essential to continue surgery safely.

RESUMEN

OBJECTIVE: The objective of this study is to elucidate the clinical and demographic profiles, as well as perioperative outcomes, of patients undergoing surgery for non-hiatal diaphragmatic hernias. Additionally, it aims to analyse these outcomes based on the surgical approach employed (transthoracic versus transabdominal). METHODS: This retrospective, observational study was conducted at a single center and involved patients diagnosed with non-hiatal diaphragmatic hernia who underwent either emergency or elective surgery between July 2007 and March 2023. Clinical characteristics and perioperative outcomes of these patients were compared using appropriate statistical tests.The research protocol for this observational, retrospective, and comparative study followed the Declaration of Helsinki's ethical requirements. The need for Clinical Research Ethics Committee approval was waived according to our institutional law because the study was a retrospective cohort study based on anonymous data of patients. Informed consent was waived because this study involved the secondary analysis of patient medical records. Additionally, this study followed the STROBE guidelines for reporting observational studies. RESULTS: The analysis included 22 patients being 59.1% men, with median age of 61 years. The predominant clinical presentation was restrictive lung disease (40.9%). The majority of cases (68%) had traumatic aetiology with a median defect size of 4 cm (range of 3-8 cm). Elective surgery was performed in 15 cases (68.1%) and transthoracic approach was employed in 13 patients (54.5%). Postoperative major morbidity reached 27.2% and mortality within 30 days was 9.1%. Emergency surgeries accounted for 44.4% of transabdominal interventions, compared to 23% in the transthoracic subgroup (p = 0.376). There were no statistically significant differences between the transabdominal and trasnthoracic approaches in terms of global postoperative complications (88.8% vs. 84.6%, p = 1), major complications (44.4% vs 15.4%, p = 0.734), mortality (11.1% v 7.6%, p = 1) and recurrence (11.1% vs 7.6%, p = 1). Postoperative stay was significantly shorter in the transthoracic subgroup (6 days vs. 14 days, p = 0.011). CONCLUSIONS: Non-hiatal diaphragmatic hernias are characterized by significant postoperative major morbidity and mortality rates, standing at 27.2% and 9.1%, respectively, accompanied by a recurrence rate of 9.1%. Both transthoracic and transabdominal approaches demonstrate comparable short- and long-term outcomes.

RESUMEN

BACKGROUND: In patients with unresectable gastric cancer and outlet obstruction syndrome, gastric partitioning gastrojejunostomy is an alternative, which could avoid the drawbacks of the standard techniques. OBJECTIVE: Comparison of antroduodenal stent, conventional gastrojejunostomy and gastric partitioning gastrojejunostomy. MATERIAL AND METHODS: A retrospective, cross-sectional study was conducted on patients with unresectable distal gastric cancer and gastric outlet obstruction, treated with the three different techniques over the last 12 years, comparing results based on oral tolerance and complications. An analysis was performed on the results using the Student-t test for independent variables. RESULTS: The 22 patients were divided in 3 groups: group I (6 cases) stent, group II (9 cases) conventional gastrojejunostomy, and group III (7 cases) gastric partitioning gastrojejunostomy, respectively. The stent allows a shorter "postoperative" stay and early onset of oral tolerance (P<0.05), however, the gastric partitioning gastrojejunostomy achieve normal diet at 15th day (P<0.05). The mortality rate was higher in the stent group (33%) compared with surgical techniques, with a morbidity of 4/6 (66.7%) in Group I, 6/9 (66.7%) Group II, and 3/7 (42%) Group III. Re-interventions: 2/6 Group I, 3/9 Group II, and 0/7 Group III. The median survival was superior in the gastric partitioning gastrojejunostomy, achieving an overall survival of 6.5 months. CONCLUSIONS: The gastric partitioning gastrojejunostomy for treatment of gastric outlet obstruction in unresectable advanced gastric cancer is a safe technique, allowing a more complete diet with lower morbidity and improved survival.
