Preliminary functional results after transanal irrigation in patients undergoing SHiP procedure for low rectal cancer

The short-stump and high-anastomosis pull-through procedure (SHiP) is a newly introduced technique in the treatment of rectal cancer. This procedure does not involve the creation of a diverting ostomy with great improvement of the patients' quality of life in the post-operative period. However, functional post-operative alterations such as low anterior rectal resection syndrome (LARS) may occur. In this context, trans-anal irrigation (TAI) may represent a viable option in the treatment and management of LARS symptoms. The aim of the present study is to investigate the role of TAI in patients operated on SHiP procedure for low rectal cancer. A prospective database of 17 patients who underwent a SHiP procedure was maintained from April 2019 to December 2021. Anal continence and functional outcomes were assessed through LARS score and Cleveland Clinic Incontinence Score (CCIS), respectively. All patients with a LARS score > 21 underwent TAI in the post-operative period. LARS median value was 36 (IQR = 8) and drastically improved after TAI treatment to 3 (IQR = 3), as the CCIS at a mean follow-up of 9 months (SD +/- 5.02). Good functional result was reached in 12 out of 13 patients (92%). Our study confirms that patients with severe post-operative dysfunction could benefit from the use of TAI

Terapia neoadiuvante nel cancro gastrico localmente avanzato: revisione della letteratura ed esperienza di un singolo centro.

Il cancro gastrico (CG) rappresenta il quarto cancro per incidenza e la seconda causa di morte legata a neoplasia nel mondo, con oltre 930.000 nuovi casi e 700.000 morti all'anno. Nel mondo l'incidenza del CG varia considerevolmente con livelli massimi in Giappone, Cina e Russia, e minimi livelli in Australia e America del Nord. L'Italia si colloca in una zona intermedia con un'incidenza più elevata nelle regioni centro-settentrionali. La chirurgia è ancora l'unica terapia curativa per il cancro gastrico ad estensione loco regionale. A tal proposito è importante ottenere margini liberi da infiltrazione neoplastica anche microscopica (R0) ed effettuare un'adeguata dissezione linfonodale. Purtroppo nella maggior parte dei casi si giunge alla diagnosi di cancro gastrico quando la malattia neoplastica è ad uno stadio localmente o diffusamente avanzato. Inoltre, anche quando è possibile realizzare una resezione con intento curativo è frequente osservare recidive nei pazienti affetti da CG. Tali considerazioni hanno portato allo sviluppo di differenti schemi terapeutici al fine di ottenere un miglioramento prognostico di questi pazienti. In aggiunta agli schemi di chemioterapia adiuvante, ampiamente studiati, molti autori hanno riportato risultati incoraggianti con l'impiego della chemioterapia neoadiuvante nel cancro gastrico localmente avanzato descrivendo in diversi articoli un miglioramento in termini di sopravvivenza globale (OS) e sopravvivenza libera da malattia (DFS). Scopo di questa tesi è fornire una panoramica quanto più completa possibile sui più recenti sviluppi in questo campo, focalizzando l'attenzione sugli effetti del trattamento neo-adiuvante nel cancro gastrico localmente avanzato. I dati presenti in letteratura suggeriscono un effetto benefico della CT neoadiuvante sulla sopravvivenza. Dal 01/2010 al 06/2014, presso l'area funzionale di Chirurgia Generale ad indirizzo addominale (direttore Prof. Andrea Renda), sono stati reclutati 24 pz affetti da adenocarcinoma gastrico localmente avanzato. Tutti i pz sono stati sottoposti a trattamento chirurgico ed in 2 casi si è fatto ricorso anche alla terapia neoadiuvante, osservando in un caso progressione di malattia ed in un altro mancato downstaging, con ripresa di malattia entro un anno. A causa del ristretto campione la nostra esperienza non ha raggiunto livelli di significatività. Tale esperienza preliminare rappresenta un punto di inizio da cui partire con l'obiettivo di aumentare il campione in esame. Sono necessari ulteriori studi con popolazioni più ampie per chiarire i diversi punti ancora controversi, quali il reale effetto sulla sopravvivenza, il rischio di ritardo nel trattamento chirurgico, la tossicità degli schemi adottati, il migliore schema terapeutico da adottare

Laparoscopic retrieval of retained intraperitoneal drain in the immediate postoperative period: report of two cases

Aim: The purpose of this study is to analyze a "rare" complication on the management of abdominal surgical drains: abdominal drainage’s retention. Starting from our experience we review literature on this topic. Material of study: We report two cases (occurred on 2004 and 2010) of retained intraperitoneal drain occurred in the immediate postoperative period after laparoscopic cholecistectomy. Results: Both patients were successfully treated by early laparoscopic removal. Discussion: We compared our experience with literature. Incidence, ethiology, prevention, diagnosis and treatment of this rare complication are analysed. We also considered the guidelines in the placement of intraperitoneal drains, the different fixation techniques, the causes of fragmentation of the drainage and removal techniques. Conclusions: Retained intraperitoneal drain secondary to fracture and adhesion in the immediate postoperative period is rare but probably underestimated surgical complication. It is impossible to know its real incidence. The role of laparoscopy is emphasized because this approach is cosmetically acceptable, contributes to early recovery and discharge of the patient, and helps to lessen the friction in worsening doctor-patient relationship

Analysis of the Effectiveness of Lornoxicam and Flurbiprofen on Management of Pain and Sequelae Following Third Molar Surgery: A Randomized, Controlled, Clinical Trial

The aim of this study was to analyze the effectiveness of Lornoxicam and Flurbiprofen in reducing perioperative sequelae after impacted mandibular third molar surgery. Ninety-one patients who needed surgical extraction of an impacted mandibular third molar were selected for the study. All subjects were randomly allocated to receive one of the following treatments twice a day for 5 days after surgery: placebo (n = 29), Flurbiprofen (n = 31), or Lornoxicam (n = 31). The primary outcome was postoperative pain, evaluated using the visual analogue scale (VAS) score at 30 min, 2, 6, 12, 24, 48 h, 7 and 10 days following surgery. The secondary outcomes chosen were changes in postoperative swelling and maximum mouth opening values compared to preoperative ones. Compared to placebo, treatment with Flurbiprofen and Lornoxicam was characterised by an improvement in the primary outcome. Moreover, the treatment with Lornoxicam presented significantly lower median pain scores at 2 h (p < 0.001) and at 6 h (p = 0.016) compared to Flurbiprofen and at 2 h (p < 0.001), 6 h (p = 0.01), and at 24 h (p = 0.018) after surgery compared with placebo. Swelling and maximum mouth opening values were not significantly different between the groups at each follow-up session. This trial demonstrated that treatment with Lornoxicam showed a decrease in the incidence and severity of pain in the first postoperative phase following third molar surgery compared to Flurbiprofen and placebo

ERas and COLorectal endoscopic surgery: an Italian society for endoscopic surgery and new technologies (SICE) national report

Background Several reports demonstrated a strong association between the level of adherence to the protocol and improved clinical outcomes after surgery. However, it is difficult to obtain full adherence to the protocol into clinical practice and has still not been identified the threshold beyond which improved functional results can be reached. Methods The ERCOLE (ERas and COLorectal Endoscopic surgery) study was as a cohort, prospective, multi-centre national study evaluating the association between adherence to ERAS items and clinical outcomes after minimally invasive colorectal surgery. The primary endpoint was to associate the percentage of ERAS adherence to functional recovery after minimally invasive colorectal cancer surgery. The secondary endpoints of the study was to validate safety of the ERAS programme evaluating complications' occurrence according to Clavien-Dindo classification and to evaluate the compliance of the Italian surgeons to each ERAS item. Results 1138 patients were included. Adherence to the ERAS protocol was full only in 101 patients (8.9%), > 75% of the ERAS items in 736 (64.7%) and > 50% in 1127 (99%). Adherence to > 75% was associated with a better functional recovery with 90.2 +/- 98.8 vs 95.9 +/- 33.4 h (p = 0.003). At difference, full adherence to the ERAS components 91.7 +/- 22.1 vs 92.2 +/- 31.6 h (p = 0.8) was not associated with better recovery. Conclusions Our results were encouraging to affirm that adherence to the ERAS program up to 75% could be considered satisfactory to get the goal. Our study could be considered a call to simplify the ERAS protocol facilitating its penetrance into clinical practice

The ChoCO-W prospective observational global study: Does COVID-19 increase gangrenous cholecystitis?

BACKGROUND: The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. METHODS: Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. RESULTS: A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p < 0.0001), diabetes (p < 0.0001), and severe chronic obstructive airway disease (p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p < 0.0001), PIPAS score (p < 0.0001), WSES sepsis score (p < 0.0001), qSOFA (p < 0.0001), and Tokyo classification of severity of acute cholecystitis (p < 0.0001) were significantly higher in the COVID-19 group. The COVID-19 group had significantly higher postoperative complications (32.2% compared with 11.7%, p < 0.0001), longer mean hospital stay (13.21 compared with 6.51 days, p < 0.0001), and mortality rate (13.4% compared with 1.7%, p < 0.0001). The incidence of gangrenous cholecystitis was doubled in the COVID-19 group (40.7% compared with 22.3%). The mean wall thickness of the gallbladder was significantly higher in the COVID-19 group [6.32 (SD: 2.44) mm compared with 5.4 (SD: 3.45) mm; p < 0.0001]. CONCLUSIONS: The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands

Model comparison from LIGO–Virgo data on GW170817’s binary components and consequences for the merger remnant

International audienceGW170817 is the very first observation of gravitational waves originating from the coalescence of two compact objects in the mass range of neutron stars, accompanied by electromagnetic counterparts, and offers an opportunity to directly probe the internal structure of neutron stars. We perform Bayesian model selection on a wide range of theoretical predictions for the neutron star equation of state. For the binary neutron star hypothesis, we find that we cannot rule out the majority of theoretical models considered. In addition, the gravitational-wave data alone does not rule out the possibility that one or both objects were low-mass black holes. We discuss the possible outcomes in the case of a binary neutron star merger, finding that all scenarios from prompt collapse to long-lived or even stable remnants are possible. For long-lived remnants, we place an upper limit of 1.9 kHz on the rotation rate. If a black hole was formed any time after merger and the coalescing stars were slowly rotating, then the maximum baryonic mass of non-rotating neutron stars is at most , and three equations of state considered here can be ruled out. We obtain a tighter limit of for the case that the merger results in a hypermassive neutron star
