La laparoscopia nelle diverticoliti acute complicate: Sigmoidectomia o Lavaggio Peritoneale Laparoscopico?

OBIETTIVI. In letteratura, non esiste un chiaro consenso riguardo al ruolo del lavaggio peritoneale laparoscopico (LPL) rispetto alla Sigmoidectomia laparoscopica (SL) nelle diverticoliti acute complicate. Lo scopo di questo studio è confrontare i pazienti sottoposti a queste due procedure chi-rurgiche ed analizzare i risultati postoperatori. MATERIALI E METODI Abbiamo considerato 30 pazienti (pts) trattati con chirurgia laparoscopica nel periodo 2013-2016 per diverticolite acuta complicata di grado II non trattabile in maniera conservativa e di grado III secondo la classificazione di Hinchey modificata. Sono stati identificati, quindi, due gruppi: Gruppo A (23 pts, 76%) sottoposti a SL e Gruppo B (7 pts, 23%) a LPL. I seguenti parametri sono stati analizzati e comparati: età media, Body Mass Index (BMI), valori di Proteina C Reattiva (PCR), Mannheim Peritonitis Index (MPI), American Society of Anesthesiologists (ASA) Score, distribuzione del grado Hinchey modificato, tempo medio operatorio, durata media della degenza post-operatoria, morbilità, tasso di reintervento e mortalità. Il t-test di Student e il test corretto di Fisher sono stati utilizzati per l’analisi statistica. Il p < 0,05 è stato considerato significativo. RISULTATI Il gruppo A e il gruppo B non sono risultati significativamente differenti per: età media (57 vs 60 anni; p = 0,705), BMI (25,57 vs 28,86 kg/m2; p = 0,090), valori di PCR (12,70 vs 12 mg/dL; p = 0,903), Mannheim Peritonitis Index (11,87 vs 14,00, p = 0,501) ed ASA score (2,74 vs 2, p = 0,226). I due gruppi hanno presentato una significativa differenza per quanto riguarda la distribuzione del grado Hinchey modificato: nel gruppo A, 9 pazienti (39%) avevano un grado Hinchey modificato pari a II e 14 (61%) un grado Hinchey Modificato III; al contrario tutti i pazienti del gruppo B avevano una diverticolite acuta di grado II (p = 0,004). Il tempo operatorio medio è risultato significativamente più lungo nel gruppo A (215 vs 64 min; p = 0,010). Non vi sono state significative differenze per quanto riguarda la durata media della degenza post-operatoria (9,50 vs 13 gg, p = 0,330) e la morbidità (30% vs 57%; p = 0,372). Il tasso di re-intervento post-operatorio è risultato significativamente più alto nel gruppo B (0 vs 28%; p = 0.009). Nessun decesso è stato identificato nei due gruppi. CONCLUSIONI Sebbene retrospettivo e con una popolazione limitata, questo studio dimostra che l' LPL può avere un ruolo nel trattamento delle diverticoliti acute complicate, principalmente nelle forme di grado II non trattabili in maniera conservativa poiché non drenabili per via percutanea, né controllabili con la sola terapia antibiotica. Questa procedura, in casi selezionati, può rappresentare una procedura efficace e sicura nel trattamento dell’infezione addominale diverticolare. L’eventuale insuccesso della LPL non pregiudica la possibilità di ricorrere successivamente ad un intervento resettivo

Cone-Beam Computed Tomographic Assessment of the Mandibular Condylar Volume in Different Skeletal Patterns: A Retrospective Study in Adult Patients

The aim of this study was to assess the condylar volume in adult patients with different skeletal classes and vertical patterns using cone‐beam computed tomography (CBCT). CBCT scans of 146 condyles from 73 patients (mean age 30   12 years old; 49 female, 24 male) were selected from the archive of the Department of Dentistry and Maxillofacial Surgery of Fondazione IRCCS Ca’ Granda, Milan, Italy, and retrospectively analyzed. The following inclusion criteria were used: adult patients; CBCT performed with the same protocol (0.4 mm slice thickness, 16   22 cm field of view, 20 s scan time); no systemic diseases; and no previous orthodontic treatments. Three‐dimensional cephalometric tracings were performed for each patient, the mandibular condyles were segmented and the relevant volumes calculated using Mimics Materialize 20.0  software (Materialise, Leuven, Belgium). Right and left variables were analyzed together using random‐intercept linear regression models. No significant association between condylar volumes and skeletal class was found. On the other hand, in relation to vertical patterns, the mean values of the mandibular condyle volumes in hyperdivergent subjects (688 mm3) with a post‐rotation growth pattern (625 mm3) were smaller than in hypodivergent patients (812 mm3) with a horizontal growth pattern (900 mm3). Patients with an increased divergence angle had smaller condylar volumes than subjects with normal or decreased mandibular plane divergence. This relationship may help the clinician when planning orthodontic treatment

Long-term, low-dose tigecycline to treat relapsing bloodstream infection due to KPC-producing Klebsiella pneumoniae after major hepatic surgery

Summary A 68-year-old male underwent a right hepatectomy, resection of the biliary convergence, and a left hepatic jejunostomy for a Klatskin tumour. The postoperative course was complicated by biliary abscesses with relapsing bloodstream infections due to Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (KPC-Kp). A 2-week course of combination antibiotic therapy failed to provide source control and the bacteraemia relapsed. Success was obtained with a regimen of tigecycline 100mg daily for 2 months, followed by tigecycline 50mg daily for 6 months, then 50mg every 48h for 3 months. No side effects were reported

Damage control strategy in perforated diverticulitis with generalized peritonitis

Background: The best treatment for perforated colonic diverticulitis with generalized peritonitis is still under debate. Concurrent strategies are resection with primary anastomosis (PRA) with or without diverting ileostomy (DI), Hartmann's procedure (HP), laparoscopic lavage (LL) and damage control surgery (DCS). This review intends to systematically analyze the current literature on DCS. Methods: DCS consists of two stages. Emergency surgery: limited resection of the diseased colon, oral and aboral closure, lavage, vacuum-assisted abdominal closure. Second look surgery after 24-48 h: definite reconstruction with colorectal anastomosis (-/+DI) or HP after adequate resuscitation. The review was conducted in accordance to the PRISMA-P Statement. PubMed/MEDLINE, Cochrane central register of controlled trials (CENTRAL) and EMBASE were searched using the following term: (Damage control surgery) AND (Diverticulitis OR Diverticulum OR Peritonitis). Results: Eight retrospective studies including 256 patients met the inclusion criteria. No randomized trial was available. 67% of the included patients had purulent, 30% feculent peritonitis. In 3% Hinchey stage II diverticulitis was found. In 49% the Mannheim peritonitis index (MPI) was greater than 26. Colorectal anastomosis was constructed during the course of the second surgery in 73%. In 15% of the latter DI was applied. The remaining 27% received HP. Postoperative mortality was 9%, morbidity 31% respectively. The anastomotic leak rate was 13%. 55% of patients were discharged without a stoma. Conclusion: DCS is a safe technique for the treatment of acute perforated diverticulitis with generalized peritonitis, allowing a high rate of colorectal anastomosis and stoma-free hospital discharge in more than half of the patients

SARS-CoV-2 vaccination modelling for safe surgery to save lives: Data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population

Postoperative pain management in non-traumatic emergency general surgery : WSES-GAIS-SIAARTI-AAST guidelines

Background Non-traumatic emergency general surgery involves a heterogeneous population that may present with several underlying diseases. Timeous emergency surgical treatment should be supplemented with high-quality perioperative care, ideally performed by multidisciplinary teams trained to identify and handle complex postoperative courses. Uncontrolled or poorly controlled acute postoperative pain may result in significant complications. While pain management after elective surgery has been standardized in perioperative pathways, the traditional perioperative treatment of patients undergoing emergency surgery is often a haphazard practice. The present recommended pain management guidelines are for pain management after non-traumatic emergency surgical intervention. It is meant to provide clinicians a list of indications to prescribe the optimal analgesics even in the absence of a multidisciplinary pain team. Material and methods An international expert panel discussed the different issues in subsequent rounds. Four international recognized scientific societies: World Society of Emergency Surgery (WSES), Global Alliance for Infection in Surgery (GAIS), Italian Society of Anesthesia, Analgesia Intensive Care (SIAARTI), and American Association for the Surgery of Trauma (AAST), endorsed the project and approved the final manuscript. Conclusion Dealing with acute postoperative pain in the emergency abdominal surgery setting is complex, requires special attention, and should be multidisciplinary. Several tools are available, and their combination is mandatory whenever is possible. Analgesic approach to the various situations and conditions should be patient based and tailored according to procedure, pathology, age, response, and available expertise. A better understanding of the patho-mechanisms of postoperative pain for short- and long-term outcomes is necessary to improve prophylactic and treatment strategies.Peer reviewe

The WSES/SICG/ACOI/SICUT/AcEMC/SIFIPAC guidelines for diagnosis and treatment of acute left colonic diverticulitis in the elderly

Acute left colonic diverticulitis (ALCD) in the elderly presents with unique epidemiological features when compared with younger patients. The clinical presentation is more nuanced in the elderly population, having higher in-hospital and postoperative mortality. Furthermore, geriatric comorbidities are a risk factor for complicated diverticulitis. Finally, elderly patients have a lower risk of recurrent episodes and, in case of recurrence, a lower probability of requiring urgent surgery than younger patients. The aim of the present work is to study age-related factors that may support a unique approach to the diagnosis and treatment of this problem in the elderly when compared with the WSES guidelines for the management of acute left-sided colonic diverticulitis. During the 1 degrees Pisa Workshop of Acute Care & Trauma Surgery held in Pisa (Italy) in September 2019, with the collaboration of the World Society of Emergency Surgery (WSES), the Italian Society of Geriatric Surgery (SICG), the Italian Hospital Surgeons Association (ACOI), the Italian Emergency Surgery and Trauma Association (SICUT), the Academy of Emergency Medicine and Care (AcEMC) and the Italian Society of Surgical Pathophysiology (SIFIPAC), three panel members presented a number of statements developed for each of the four themes regarding the diagnosis and management of ALCD in older patients, formulated according to the GRADE approach, at a Consensus Conference where a panel of experts participated. The statements were subsequently debated, revised, and finally approved by the Consensus Conference attendees. The current paper is a summary report of the definitive guidelines statements on each of the following topics: diagnosis, management, surgical technique and antibiotic therapy.Peer reviewe

The LIFE TRIAD of emergency general surgery

Emergency General Surgery (EGS) was identified as multidisciplinary surgery performed for traumatic and non-traumatic acute conditions during the same admission in the hospital by general emergency surgeons and other specialists. It is the most diffused surgical discipline in the world. To live and grow strong EGS necessitates three fundamental parts: emergency and elective continuous surgical practice, evidence generation through clinical registries and data accrual, and indications and guidelines production: the LIFE TRIAD.Peer reviewe
