During OLV in lateral decubitus for thoracic surgery, application to the dependent lung a recruiting strategy significantly recruits the dependent lung, improving arterial oxygenation and respiratory mechanics until the end of surgery. However, the transient haemodynamic derangement occurring during the RM should be taken into account.

IntroductionHepatocellular carcinoma (HCC) is the sixth most common cancer. Spontaneous rupture of HCC is an acute complication with a high mortality rate. The HCC principally arises in the background of chronic liver disease and cirrhosis of the liver. In the last few years, the rising incidence of HCC in noncirrhotic liver suggests the presence of other factors that may play a role in liver carcinogenesis.MethodsWe reviewed all cases treated at the University Surgical Department of Ospedali Riuniti of Foggia from 2009 to 2018. Only a single case of hemoperitoneum caused by spontaneous rupture of HCC in noncirrhotic liver was found. An extensive search of the relevant literature was carried out using MEDLINE, and a total of 58 published studies were screened from the sources listed.ConclusionsThe management of this devastating emergency should be carefully analyzed, with stabilization of vital signs as soon as possible. Patient with ruptured HCC and hemoperitoneum without a prior history of cirrhosis and viral infections benefited from the role of transcatheter arterial embolization (TAE) as the preliminary treatment in order to have a more precise diagnosis and an optimal stabilization of the patient. Delayed or staged hepatectomy after TAE represents the definitive treatment.

Introduction Various surgical societies constantly update their recommendations in order to adapt surgical activity on current Pandemic conditions. The aim of this study is to analyze how hospitalizations and emergency operations have changed in our Department of Medical and Surgical Sciences in the Hospital of Foggia during covid-19 pandemic. Methods Our cohort-study was conducted by analyzing two groups of patients admitted to the Department of Medical and Surgical Sciences of the Hospital of Foggia: those admitted during the no-covid period from March 09th, 2019 to May 09th, 2019 and those during the covid period from March 09th, 2020 to May 09th, 2020. Results A total of 750 patients admitted during the no-covid period of 2019 and 171 during the covid period of 2020, of these 222 were emergency admission during 2019 and 97 during 2020, 528 were elective admission during 2019 and 74 during 2020. Of the emergency admissions (222 during 2019 and 97 during 2020), 91 were operated during the no covid period in 2019 and 52 during the covid period in 2020. The mean Mannheim Peritonitis Index Score, that is a scoring system used in peritonitis which is simple and cost-effective, were 15.6 during the no covid period of 2019 and 22.2 during the covid period of 2020. We observed 29 post-operative complications during 2019 and 26 during 2020. Conclusions Contraction of admissions for urgent and emergent conditions in the first period of lockdown has been followed from some positive effects as well as aggravating consequences.

Background There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates. Methods We conducted an international cohort study to determine all-cause and COVID-19-specific 30-day morbidity and mortality of BS performed between 01/05/2020 and 31/10/2020. Results Four hundred ninety-nine surgeons from 185 centres in 42 countries provided data on 7704 patients. Elective primary BS (n = 7084) was associated with a 30-day morbidity of 6.76% (n = 479) and a 30-day mortality of 0.14% (n = 10). Emergency BS, revisional BS, insulin-treated type 2 diabetes, and untreated obstructive sleep apnoea were associated with increased complications on multivariable analysis. Forty-three patients developed symptomatic COVID-19 postoperatively, with a higher risk in non-whites. Preoperative self-isolation, preoperative testing for SARS-CoV-2, and surgery in institutions not concurrently treating COVID-19 patients did not reduce the incidence of postoperative COVID-19. Postoperative symptomatic COVID-19 was more likely if the surgery was performed during a COVID-19 peak in that country. Conclusions BS can be performed safely during the COVID-19 pandemic with appropriate perioperative protocols. There was no relationship between preoperative testing for COVID-19 and self-isolation with symptomatic postoperative COVID-19. The risk of postoperative COVID-19 risk was greater in non-whites or if BS was performed during a local peak.

Background and objectives: The principal complications associated with thyroid surgery consist in postoperative recurrent laryngeal nerve (RLN) palsy, hypoparathyroidism, intra-operative and post-operative hemorrhage. In this paper, structured as a literature review, we describe the current knowledge and the technical improvements currently employed in the field of thyroid surgery, focusing on the contribution of energy based devices in relation with the reduction of the operating time and the odds of possible complication. Materials and methods: a relevant systematic literature search on Pubmed was carried out including works from 2004 through 2019, selecting studies providing information on the energy based devices employed in surgeries and statistic data concerning RNL (transient and permanent) injury and operative time. Results: Nineteen studies were reviewed, dealing with 4468 patients in total. The operative variables considered in this study are: employed device, number of patients, pathological conditions affecting the patients, surgical treatment, RNL injury percentage and the operating time, offering an insight on different patient conditions and their relative operative outcomes. A total of 1843 patients, accounting to the 41.2% of the total pool, underwent the traditional technique operation, while 2605 patients (58.3%) were treated employing the energy based devices techniques. Thyroidectomy performed by approaches different from traditional (for example robotic, MIVAT (Mini Invasive Video Assisted thyroidectomy)) were excluded from this study. Conclusions: The energy-based vessel sealing devices in study, represent a safe and efficient alternative to the traditional clamp-and-tie hand technique in the thyroidal surgery scenario, granting a reduction in operating time while not increasing RNL injury rates. According to this information, a preference for energy based devices techniques might be expressed, furthermore, a progressively higher usage rate for these devices is expected in the near future.

Summary Background Metabolic and bariatric surgery (MBS) is an effective treatment for adolescents with severe obesity. Objectives This study examined the safety of MBS in adolescents during the coronavirus disease 2019 (COVID‐19) pandemic. Methods This was a global, multicentre and observational cohort study of MBS performed between May 01, 2020, and October 10,2020, in 68 centres from 24 countries. Data collection included in‐hospital and 30‐day COVID‐19 and surgery‐specific morbidity/mortality. Results One hundred and seventy adolescent patients (mean age: 17.75 ± 1.30 years), mostly females (n = 122, 71.8%), underwent MBS during the study period. The mean pre‐operative weight and body mass index were 122.16 ± 15.92 kg and 43.7 ± 7.11 kg/m2, respectively. Although majority of patients had pre‐operative testing for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) (n = 146; 85.9%), only 42.4% (n = 72) of the patients were asked to self‐isolate pre‐operatively. Two patients developed symptomatic SARS‐CoV‐2 infection post‐operatively (1.2%). The overall complication rate was 5.3% (n = 9). There was no mortality in this cohort. Conclusions MBS in adolescents with obesity is safe during the COVID‐19 pandemic when performed within the context of local precautionary procedures (such as pre‐operative testing). The 30‐day morbidity rates were similar to those reported pre‐pandemic. These data will help facilitate the safe re‐introduction of MBS services for this group of patients.

Introduction The COVID-19 pandemic is having a deep impact on emergency surgical services, with a significant reduction of patients admitted into emergency surgical units world widely. Reliable figures of this reduction have not been produced yet. Our international audit aimed at giving a precise snapshot of the absolute and relative changes of emergency surgical admissions at the outbreak of the pandemic. Materials and methods Datasets of patients admitted as general surgical emergencies into 45 internationally distributed emergency surgical units during the months of March and April 2020 (Covid-19 pandemic outbreak) were collected and compared with those of patients admitted into the same units during the months of March and April 2019 (pre-Covid-19). Primary endpoint was to evaluate the relative variation of the presentation symptoms and discharge diagnoses between the two study periods. Secondary endpoint was to identify the possible change of therapeutic strategy during the same two periods. Results Forty-five centres participated sent their anonymised data to the study hub, for a total of 6263 patients. Of these, 3810 were admitted in the pre-Covid period and 2453 in the Covid period, for a 35.6% absolute reduction. The most common presentation was abdominal pain, whose incidence did not change between the two periods, but in the Covid period patients presented less frequently with anal pain, hernias, anaemia and weight loss. ASA 1 and low frailty patients were admitted less frequently, while ASA>1 and frail patients showed a relative increase. The type of surgical access did not change significantly, but lap-to-open conversion rate halved between the two study periods. Discharge diagnoses of appendicitis and diverticulitis reduced significantly, while bowel ischaemia and perianal ailments had a significant relative increase. Conclusions Our audit demonstrates a significant overall reduction of emergency surgery admissions at the outbreak of the Covid-19 pandemic with a minimal change of the proportions of single presentations, diagnoses and treatments. These findings may open the door to new ways of managing surgical emergencies without engulfing the already busy hospitals.

Background: The treatment for sliding esophageal hernia with mild gastroesophageal reflux is usually conservative, but surgical treatment is recommended for refractory sliding esophageal hernia, paraesophageal hernia liable to prolapse, or paraesophageal hernia with ulceration and/or stenosis. Robotic surgery overcomes laparoscopic pitfalls by providing steady-state three-dimensional visualization, augmented dexterity with endo-wrist movements, and superior ergonomics for the surgeon. Case presentation: To investigate robotic paraesophageal hernia repair, a literature search was conducted using PubMed with the following key words: mini invasive surgery, robotic surgery, hiatal hernia, and Nissen fundoplication. We present the case of a 44-year-old Italian woman with a 20-year history of gastroesophageal reflux disease refractory to medical treatment, who underwent robotic Nissen fundoplication. In our center, we use the da Vinci® Xi™ Surgical System, which is an advanced tool for minimally invasive surgery. Conclusions: Various reports published in the literature suggested that the robot-assisted approach was effective and was associated with very low postoperative morbidity and was accompanied by satisfactory symptomatic and anatomical radiological outcomes during a follow-up period. The robotic approach to paraesophageal repair is safe and effective with low complication rates. With increased experience, the operative time, length of stay, and complications decrease without compromising surgical principles.
