RESUMO
Anorectal emergencies comprise a wide variety of diseases that share common symptoms, i.e., anorectal pain or bleeding and might require immediate management. While most of the underlying conditions do not need inpatient management, some of them could be life-threatening and need prompt recognition and treatment. It is well known that an incorrect diagnosis is frequent for anorectal diseases and that a delayed diagnosis is related to an impaired outcome. This paper aims to improve the knowledge and the awareness on this specific topic and to provide a useful tool for every physician dealing with anorectal emergencies.The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the boards of the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the WSES-AAST-WJES Consensus Conference on Anorectal Emergencies, and for each statement, a consensus among the WSES-AAST panel of experts was reached. We structured our work into seven main topics to cover the entire management of patients with anorectal emergencies and to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

BACKGROUND: Nowadays, very few patients with non-variceal upper gastrointestinal bleeding fail endoscopic hemostasis (refractory NVUGIB). This subset of patients poses a clinical dilemma: should they be operated on or referred to transcatheter arterial embolization (TAE)? OBJECTIVES: To carry out a systematic review of the literature and to perform a meta-analysis of studies that directly compare TAE and surgery in patients with refractory NVUGIB. MATERIALS AND METHODS: We searched PubMed, Ovid MEDLINE, and Embase. A combination of the MeSH terms "gastrointestinal bleeding"; "gastrointestinal hemorrhage"; "embolization"; "embolization, therapeutic"; and "surgery" were used (("gastrointestinal bleeding" or "gastrointestinal hemorrhage") and ("embolization" or "embolization, therapeutic") and "surgery")). The search was performed in June 2018. Studies were retrieved and relevant studies were identified after reading the study title and abstract. Bibliographies of the selected studies were also examined. Statistical analysis was performed using RevMan software. Outcomes considered were all-cause mortality, rebleeding rate, complication rate, and the need for further intervention. RESULTS: Eight hundred fifty-six abstracts were found. Only 13 studies were included for a total of 1077 patients (TAE group 427, surgery group 650). All selected papers were non-randomized studies: ten were single-center and two were double-center retrospective comparative studies, while only one was a multicenter prospective cohort study. No comparative randomized clinical trial is reported in the literature.Mortality. Pooled data (1077 patients) showed a tendency toward improved mortality rates after TAE, but this trend was not statistically significant (OD = 0.77; 95% CI 0.50, 1.18; P = 0.05; I 2 = 43% [random effects]). Significant heterogeneity was found among the studies.Rebleeding rate. Pooled data (865 patients, 211 events) showed that the incidence of rebleeding was significantly higher for patients undergoing TAE (OD = 2.44; 95% CI 1.77, 3.36; P = 0.41; I 2 = 4% [fixed effects]).Complication rate. Pooling of the data (487 patients, 206 events) showed a sharp reduction of complications after TAE when compared with surgery (OD = 0.45; 95% CI 0.30, 0.47; P = 0.24; I 2 = 26% [fixed effects]).Need for further intervention. Pooled data (698 patients, 165 events) revealed a significant reduction of further intervention in the surgery group (OD = 2.13; 95% CI 1.21, 3.77; P = 0.02; I 2 = 56% [random effects]). A great degree of heterogeneity was found among the studies. CONCLUSIONS: The present study shows that TAE is a safe and effective procedure; when compared to surgery, TAE exhibits a higher rebleeding rate, but this tendency does not affect the clinical outcome as shown by the comparison of mortality rates (slight drift toward lower mortality for patients undergoing TAE). The present study suggests that TAE could be a viable option for the first-line therapy of refractory NVUGIB and sets the foundation for the design of future randomized clinical trials. LIMITATIONS: The retrospective nature of the majority of included studies leads to selection bias. Furthermore, the decision of whether to proceed with surgery or refer to TAE was made on a case-by-case basis by each attending surgeon. Thus, external validity is low. Another limitation involves the variability in etiology of the refractory bleeding. TAE techniques and surgical procedure also differ consistently between different studies. Frame time for mortality detection differs between the studies. These limitations do not impair the power of the present study that represents the largest and most recent meta-analysis currently available.

Background: Acute appendicitis (AA) is the most common surgical disease, and appendectomy is the treatment of choice in the majority of cases. A correct diagnosis is key for decreasing the negative appendectomy rate. The management can become difficult in case of complicated appendicitis. The aim of this study is to describe the worldwide clinical and diagnostic work-up and management of AA in surgical departments. Methods: This prospective multicenter observational study was performed in 116 worldwide surgical departments from 44 countries over a 6-month period (April 1, 2016-September 30, 2016). All consecutive patients admitted to surgical departments with a clinical diagnosis of AA were included in the study. Results: A total of 4282 patients were enrolled in the POSAW study, 1928 (45%) women and 2354 (55%) men, with a median age of 29 years. Nine hundred and seven (21.2%) patients underwent an abdominal CT scan, 1856 (43.3%) patients an US, and 285 (6.7%) patients both CT scan and US. A total of 4097 (95.7%) patients underwent surgery; 1809 (42.2%) underwent open appendectomy and 2215 (51.7%) had laparoscopic appendectomy. One hundred eighty-five (4.3%) patients were managed conservatively. Major complications occurred in 199 patients (4.6%). The overall mortality rate was 0.28%. Conclusions: The results of the present study confirm the clinical value of imaging techniques and prognostic scores. Appendectomy remains the most effective treatment of acute appendicitis. Mortality rate is low.

BACKGROUND: Left-sided gallbladder without situs viscerum inversus (LSG-woSVI) is a rare congenital anomaly. Clinical features and routine presurgical imaging could miss the anomalous position, thereby producing complications during surgery. Laparoscopic cholecystectomy can be performed safely, but the risk of bile duct injury (BDI) is greater than in cholecystectomy of the orthotopic gallbladder. We present a retrospective review of all scientific literature for diagnosed cases of LSG-woSVI undergoing cholecystectomy from 1996 to 2014. Our objectives were to outline empirical top tips for a safe cholecystectomy in incidentally diagnosed LSG-woSVI. METHODS: We carried a comprehensive search of PubMed using medical subject headings "left-sided gallbladder," "right-sided ligamentum teres" "situs viscerun inversus," "preoperative diagnoses," "cholecystectomy," and "bile duct injury." We considered a classification of the LSG-woSVI in 2 groups: True LSG-woSVI and LSG-woSVI in patients with right-sided ligamentum teres. RESULTS: Our retrospective review revealed 55 cases of LSG-woSVI. The mean age was 51 years ±17 SD, male/female ratio was 2:1, clinical presentation was pain in the right upper abdominal quadrant in 75.5%, preoperative diagnosis was reached in 16.3%, True LSG was diagnosed in 83%, acute cholecystitis was found in 50%, laparoscopic cholecystectomy was performed in 79.6%, fundus-first dissection technique was used in 16.7%, intraoperative cholangiography was performed in 39.1%, and BDI occurred in 7.3% of the reported cases. CONCLUSIONS: Increased awareness of the anatomic aberrations in LSG-woSVI associated with improved preoperative diagnosis and a good knowledge about safe surgical techniques for cholecystectomy could indubitably reduce the incidence of BDI.

BACKGROUND: Gastric cancer mortality rates have remained relatively unchanged over the past decades, in spite of progressive decrease in incidence. Nodal status represents a key factor for prognostic assessment, allowing a tailored-made adjuvant therapy for the patients. The aim of this study is to evaluate the prognostic influence of different nodal involvement indicators on the overall survival in a large series of patients submitted to gastrectomy at our Institution. METHODS: we retrospectively collected data from 634 newly diagnosed patients with gastric cancer who underwent curative gastrectomy, with D1/D2 lymphadenectomy during the last 20 years. Prognostic values of age, histologic type, pN, nodal ratio (LNR) and log odds of positive lymph nodes (LODDS) of were analyzed. RESULTS: The median overall survival was 40.2 +/-31 months. Multivariate analysis identified age at diagnosis, diffuse-type tumor, pN and LODDS as independent predictors of worse prognosis. Scatter plots of relationships between LODDS and LNR showed that LODDS seems to better assesses prognosis for patients at LNR stage 0 or 1. CONCLUSIONS: Nodal involvement confirmed to be a strong indicator of prognosis. LODDS demonstrated a theoretical advantage over pN and LNR system allowing more accurate patients stratification, but our results have to be confirmed by further trials.

BACKGROUND: Clinical trials have so far shown controversial results as regards the standard of care for treating uncomplicated acute appendicitis (uC-AA). High operational risk adult patients (HORAP) could represent selected patients where primary antibiotic conservative therapy (pACT or A) could be indicated. METHODS: We carried a comprehensive search of the PubMed searching engine in the English language scientific literature from 1995 to 2015, using medical subject headings "antibiotics", "uncomplicated appendicitis", "appendicectomy", "conservative treatment", "surgery" and "randomized clinical trial". All RCTs comparing the outcomes of pACT versus primary surgical open or laparoscopic appendectomy (pSOLA or S) as primary treatment options for uC-AA were identified. Inclusion criteria for our analytical review were RCTs evaluating outcomes in terms of or related to all of the following four parameters: treatment efficacy, post therapeutic/operative complications, in hospital length of stay (LOS) and recurrence. RESULTS: The conclusion of all five RCTs considered antibiotics alone in the treatment of AA as an efficient and non inferior therapeutic option respect to surgery. Primary ACT was characterised by a higher LOS, a higher rate of recurrence and a lower rate of postoperative complication than pSOLA. CONCLUSIONS: Based on the current body of evidence, an appropriate pACT could be a rational tailored primary treatment option for CT proven uC-AA in HORAP. Accurate diagnoses and surgical risk stratification in patients with uC-AA could aid decision making for target therapy. However, results of large sample prospective multicenter RCTs are required to routinely recommend pACT for uC-AA in the clinical practice.

BACKGROUND: The HARMONIC SCALPEL (H) is an advanced ultrasonic cutting and coagulating surgical device with important clinical advantages, such as: reduced ligature demand; greater precision due to minimal lateral thermal tissue damage; minimal smoke production; absence of electric corrents running through the patient. However, there are no prospective RCTs demonstrating the advantages of H compared to the conventional monopolar diathermy (MD) during laparoscopic cholecystectomy (LC) in cases of acute cholecystitis (AC). METHODS: This study was a prospective, single-center, randomized trial (Trial Registration Number: NCT00746850) designed to investigate whether the use of H can reduce the incidence of intra-operative conversion during LC in cases of AC, compared to the use of MD. Patients were divided into two groups: both groups underwent early LC, within 72 hours of diagnosis, using H and MD respectively (H = experimental/study group, MD = control group). The study was designed and conducted in accordance with the regulations of Good Clinical Practice. RESULTS: 42 patients were randomly assigned the use of H (21 patients) or MD (21 patients) during LC. The two groups were comparable in terms of basic patient characteristics. Mean operating time in the H group was 101.3 minutes compared to 106.4 minutes in the control group (p=ns); overall blood loss was significantly lower in the H group. Conversion rate was 4.7% for the H group, which was significantly lower than the 33% conversion rate for the control group (p<0.05). Post-operative morbidity rates differed slightly: 19% and 23% in the H and control groups, respectively (p=ns). Average post-operative hospitalization lasted 5.2 days in the H group compared to 5.4 days in the control group (p=ns). CONCLUSIONS: The use of H appears to correlate with reduced rates of laparoscopic-open conversion. Given this evidence, H may be more suitable than MD for technically demanding cases of AC.
RESUMO
BACKGROUND: The first reliable statistic data about perioperatory mortality were published in 1841 by the French Joseph-Francois Malgaigne (1806-1863): he referred to a mean mortality of 60% for amputations and this bad result was to be attributed mainly to hospital acquired diseases. The idea of "hospital acquired disease" although vague, included five infective nosologic entities, which at that time were diagnosed more frequently: erysipelas, tetan, pyemia, septicemia, and gangrene. Nonetheless, the suppuration with pus production was considered from most of the surgeons and doctors of that time as a necessary and unavoidable step in the process of wound healing. During the end of the eighteenth century, hospitals of the main European cities were transforming into aggregations of several wards, where the high concentration of patients created poor sanitary conditions and a consistent increase of perioperatory mortality. In 1865, Lister applied his first antiseptic dressing on the surface of an exposed fracture. These experimental attempts lead to an effective reduction of wound infections respect to the dressing with strings used previously. DISCUSSION: Lister's innovations in the field of wound treatment were based on two brand new concepts: germs causing rot were ubiquitarious and the wound infection was not a normal step in the process of wound healing. The concept of antisepsis was hardly accepted in the European surgical world: "Of all countries, Italy is the most indifferent and uninterested in experimenting this method, which has been so favorably judged from the greatest surgical societies in Germany". This quotation from the young surgeon Giuseppe Ruggi (1844-1925) from Bologna comes from his article where he presented his first experiences on aseptic medications started the previous year in the Surgical Department of Maggiore Hospital in Bologna. In his report, Ruggi described the adopted technique and suggested that the medication should be extended to all the surgical patients of the hospital:" this is needed to totally remove from the hospital all those elements of infection which grow in the wounds dressed with the old method". The experimentation of this new dressing for the few treated cases was rigorous and concerned both the sterilization of surgical tools with the fenic acid (5%) and the shaving of the skin. Ruggi also observed that there was no correlation between the seriousness of the wound and its extension or way of healing: when "simple" cases that "should heal without complication" showed fever he often realized that "it was often due to a medication performed without following the rules for an accurate disinfection and dressing". Ruggi thought that the fever was connected to "reabsorption of pyrogenic substances, which can be removed cleaning and disinfecting the wound" in cases of wounds not accurately dressed and rarely medicated. Frequent postoperative medications of the wound were able to eliminate the fever within 2 h. Ruggi's attitude toward the fine reasoning lead him to introduce the concept of immunodeficiency related to physical deterioration: " patients treated for surgical disease may sometimes suffer from complications of medical conditions, which initially escape the most accurate investigations The surgical operation could, in some cases, hold the balance of power". CONCLUSIONS: The obtained results, published in 1879, appear extremely interesting. As he wrote in 1898, for the presentation of his case record of more than 1000 laparotomies, he had started " operating as a young surgeon without any tutor, helped only by his mind and what he could deduce from publications existing at the moment ".

BACKGROUND: Today, we do not have a universally accepted evidence on how to treat peritoneal carcinomatosis (PC) from colorectal cancer (CRC) in international guidelines. METHODS: The present study is a review of the literature investigating current strategies to treat CRC PC. RESULTS: Despite the progresses of systemic chemotherapy, the presence of PC among patients with metastatic CRC reduces the overall survival to 30 %, and only 4 % of patients with PC from CRC treated are alive for 5 years. Many trials evaluate the combined treatment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for CRC PC, suggesting a survival benefit in highly selected patients. Only one trial is randomized and presents some biases. The two main prognostic factors are Peritoneal Cancer Index (PCI) and completeness of cytoreduction score (CC score). There is no universal agreement on how to approach the synchronous presence of PC and liver metastasis with a curative intent during the same procedure. A growing interest among the scientific community has arisen about systematic second-look surgery and HIPEC treatment in high-risk patients. CONCLUSION: Current evidences suggest that CRS and HIPEC might be beneficial in highly selected patients affected with PC from CRC. Anyway, today, there is a shortage of well-designed phase 3 trials.
