RESUMO
Leiomyosarcomas (LMSs) are rare tumors originating from the muscular layer. We performed a literature review of cases of confirmed rectal leiomyosarcomas (rLMSs) to clarify the history of such an infrequent tumor arising at such an uncommon location. In this research local recurrence was related to poorly differentiated rLMS and no other association between recurrence and any criteria was found. Concerning overall survival (OS), rLMS patients developing recurrence presented shorter longevity compared with the group without.

BACKGROUND: Early colorectal cancer (ECC) is defined as T1NXM0 colorectal cancer (CRC). Although a non-negligible number of T1-CRCs presents metastatic lymph-nodes, local excision is increasingly proposed as alternative to radical resection. Several criteria have been suggested to identify low-risk T1-CRC, but recommendations on this topic are still heterogeneous. This study aims to identify criteria associated with N+ T1-CRC, to select patients to undergo (or not) local excision. METHODS: A retrospective analysis of demographic, clinical, and histology criteria of 122 consecutive T1-CRC patients undergoing radical resection at Parma University Hospital between 2000 and 2018 has been performed. RESULTS: Lymph-node metastasis (LNM) was observed in 15/122 patients (12.3%). No LNM was observed among well-differentiated (G1) tumors (0/37), while 10/65 (15.4%) G2 cases as well as 5/20 (25%) G3 patients presented LNM. G1 was associated with absence of LNM (p = 0.013). After excluding G1 patients, the rate of N + T1-CRC was 17.6% (15/85). LNM was observed in 4/8 (50%) patients with lymphovascular invasion (LVI) and in 11/77 (14.2%) without LVI. LVI resulted being associated with LNM (p < 0.042). LNM was reported in 28.3% of cases with a tumor infiltration >4.25 mm (13/46), compared to 5.1% in cases with an infiltration ≤4.25 mm (2/39) (p = 0.012). In Cox regression analysis, the higher hazard ratio (HR) was reported for the LVI + and infiltration >4.25 mm (HR 24.849). CONCLUSIONS: In patients with ECC (pT1NXM0), good differentiation (G1), absence of lymphovascular invasion (LVI-), and tumor radial infiltration ≤4.25 mm may allow performing local resection and avoiding radical surgery.

PURPOSE: In colorectal cancer (CRC), lymphovascular invasion (LVI) is a predictor of poor outcome and its analysis is nowadays recommended. Literature is still extremely heterogeneous, and we hypothesize that, within such a group of patients, there are any further predictors of survival. METHODS: A total of 2652 patients with I-III-stage CRC undergoing resection between 2002 and 2018 were included in a retrospective analysis of demographic, clinical, and histology with the aim of defining the impact of LVI on overall survival (OS) and its relationship with other prognostic factors. RESULTS: Overall, 5-year-OS was 62.6% (77-month-median survival). LVI was found in 558 (21%) specimens and resulted associated with 44.9%-5-year-OS (44 months) vs. 64.1% (104 months) of LVI cases. At multivariate analysis, LVI (p = 0.009), T3-4 (p < 0.001), and N ≠ 0 (p < 0.001) resulted independent predictors of outcome. LVI resulted as being associated with older age (p < 0.013), T3-4 (p < 0.001), lower grading (p < 0.001), N ≠ 0 (p < 0.001), mucinous histology (p < 0.001), budding (p < 0.001), and PNI (p < 0.001). Within the LVI + patients, T3-4 (p = 0.009) and N ≠ 0 (p < 0.001) resulted as independent predictors of shortened OS. In particular, N-status impacted the prognosis of patients with T3-4 tumors (p = 0.020), whereas it did not impact the prognosis of patients with T1-2 tumors (p = 0.393). Three groups (T1-2anyN, T3-4N0, T3-4 N ≠ 0), with distinct outcome (approximately 70%-, 52%-, and 35%-5-year-OS, respectively), were identified. CONCLUSIONS: LVI is associated with more aggressive/more advanced CRC and is confirmed as predictor of poor outcome. By using T- and N-stage, a simple algorithm may easily allow re-assessing the expected survival of patients with LVI + tumors.

Preoperative biliary drainage (PBD) prior to pancreatoduodenectomy (PD) has gained popularity as bridge management to resolve jaundice, but its role is being challenged as it is thought to increase morbidity. To clarify the current recommendations for PBD prior to PD, we reviewed the literature, including all relevant articles published in English up until December, 2015. There is increasing evidence that PBD causes bile infection, which is related to the morbidity of infectious complications. Results of transhepatic drainage are poorer than those of endoscopic stenting, especially in an oncologic setting, although it is still unclear whether metallic stents are superior to nasobiliary drainage. PBD should be avoided whenever possible and performed only in selected cases, such as the emergency setting, an inevitable long delay (>4 weeks) before PD, and jaundice-related anorexia. Seemingly, transhepatic drainage should be reserved for refractory cases if endoscopic drainage is not possible. Further studies comparing endoscopic drainage techniques, such as metallic stents and nasobiliary drainage, are required to assess the most effective technique of PBD. Bile infection should be prevented by adequate antibiotic prophylaxis and treated even in the absence of symptoms, and bile status should be assessed systematically.

BACKGROUND: Surgical innovation from surgeon's standpoint has never been scrutinized as it may lead to understand and improve surgical innovation, potentially to refine the IDEAL (Idea, Development, Exploration, Assessment, Long-term Follow-up) recommendations. METHODS: A qualitative analysis was designed. A purposive expert sampling was then performed in organ transplant as it was chosen as the ideal model of surgical innovation. Interviews were designed, and main themes included the following: definition of surgical innovation, the decision-making process of surgical innovation, and ethical dilemmas. A semistructured design was designed to analyze the decision-making process, using the Forces Interaction Model. An in-depth design with open-ended questions was chosen to define surgical innovation and ethical dilemmas. RESULTS: Interviews were performed in 2014. Participants were 7 professors of surgery: 3 in liver transplant, 2 in heart transplant, and 2 in face transplant. Saturation was reached. They demonstrated an intuitive understanding of surgical innovation. Using the Forces Interaction Model, decision leading to contemporary innovation results mainly from collegiality, when the surgeon was previously the main factor. The patient is seemingly lesser in the decision. A perfect innovative surgeon was described (with resiliency, legitimacy, and no technical restriction). Ethical conflicts were related to risk assessment and doubts regarding methodology when most participants (4/7) described ethical dilemma as being irrelevant. CONCLUSIONS: Innovation in surgery is teamwork. Therefore, it should be performed in specific specialized centers. Those centers should include Ethics and Laws department in order to integrate these concepts to innovative process. This study enables to improve the IDEAL recommendations and is a major asset in surgery.
RESUMO
BACKGROUND AND OBJECTIVES: Anastomotic recurrence (AR), whose etiopathogenesis is attributed to intraluminal implantation of cancerous cells or metachronous carcinogenesis, is a major issue for patients undergoing colon cancer (CC) resection. The objective of the study is to throw some light on AR etiopathogenesis and to identify risk factors of AR in selecting patients to undergo early endoscopy. METHODS: An analysis of clinical and histopathological parameters, including MSI and LOH of seven sites (Myc-L, BAT26, BAT40, D5S346, D18S452, D18S64, D16S402) was performed in primary CC and AR of 18 patients. They were then compared to 36 controls not developing AR. RESULTS: A genetic instability was present in 16/18 patients, with distinct genetic patterns between primaries and ARs. LOH at 5q21 and/or 18p11.23 were found in both primary and AR in >50% of cases, but this rate was no different from control population. CEA resulted as associated with AR (P = 0.03), whereas N status presented a borderline result (P = 0.08). CONCLUSIONS: Our findings challenge present theories about AR development. No "genetic marker" has been found. CEA and, to a lesser extent, N status, appear associated with AR. Rectal washout is seemingly meaningless. Iterative resection should be recommended since a long survival may be expected. J. Surg. Oncol. 2016;114:228-236. © 2016 Wiley Periodicals, Inc.

Acute diverticulitis (AD) is associated with relevant morbidity/mortality and is increasing worldwide, thus becoming a major issue for national health systems. AD may be challenging, as clinical relevance varies widely, ranging from asymptomatic picture to life-threatening conditions, with continuously evolving diagnostic tools, classifications, and management. A 33-item-questionnaire was administered to residents and surgeons to analyze the actual clinical practice and to verify the real spread of recent recommendations, also by stratifying surgeons by experience. CT-scan remains the mainstay of AD assessment, including cases presenting with recurrent mild episodes or women of child-bearing age. Outpatient management of mild AD is slowly gaining acceptance. A conservative management is preferred in non-severe cases with extradigestive air or small/non-radiologically drainable abscesses. In severe cases, a laparoscopic approach is preferred, with a non-negligible number of surgeons confident in performing emergency complex procedures. Surgeons are seemingly aware of several options during emergency surgery for AD, since the rate of Hartmann procedures does not exceed 50% in most environments and damage control surgery is spreading in life-threatening cases. Quality of life and history of complicated AD are the main indications for delayed colectomy, which is mostly performed avoiding the proximal vessel ligation, mobilizing the splenic flexure and performing a colorectal anastomosis. ICG is spreading to check anastomotic stumps' vascularization. Differences between the two experience groups were found about the type of investigation to exclude colon cancer (considering the experience only in terms of number of colectomies performed), the size of the peritoneal abscess to be drained, practice of damage control surgery and the attitude towards colovesical fistula.
RESUMO
BACKGROUND: Hyperpyrexia associated with right iliac fossa pain and tenderness in a young patient is a common finding in an Emergency Department, and is frequently caused by acute appendicitis or genitourinary affliction. Especially in the case of young males, it is debated whether the patient should undergo immediate surgery or be referred for imagery, and, when surgery is finally planned, whether an open incision of the iliac fossa or a laparoscopic approach is preferred. OBJECTIVE: We describe a case of a patient with a twisted, ischemic ileal hemangioma mimicking an acute appendicitis, which was diagnosed and managed laparoscopically. CASE REPORT: A 16-year-old boy was admitted to the Emergency Department with a 2-day history of hyperpyrexia, nausea, right iliac fossa pain, and tenderness. Perioperative computed tomography scan showed a 3-cm image that was interpreted as a periappendicular abscess. At laparoscopy, a twisted ischemic mass adherent to the surrounding ileum was located and removed. The patient's outcome was uneventful. Pathology showed a benign hemangioma of the ileal mesentery. To our knowledge, this is the first case treated by laparoscopic resection. CONCLUSIONS: Rare conditions, such as peduncolated tumors, can mimic common conditions like acute appencitis. Also, due to the aspecificity of symptoms and difficult interpretation of imagery, diagnosis can be difficult to achieve preoperatively and surgery can be challenging. Laparoscopy can allow a diagnosis to be made and the appropriate treatment to be performed without the need for laparotomy. Rare causes of appendicitis-like syndrome represent an argument in favor of a laparoscopic approach, even in the case of young male patients.

The COVID-19 pandemic outbreak delayed interventions of elective surgery worldwide. In Italy, the first western country to be affected, 410000 operations formerly planned were cancelled with the beginning of the first wave. Symptomatic cholelithiasis represents one of the most common, benign medical conditions in the world leading the affected patients to general surgeons'attention; in 0.5% of cases gallstones (symptomatic or not) can complicate with acute lithiasic cholecystitis (ALC) whose universally acknowledged treatment of choice is laparoscopic cholecystectomy. Delaying in surgery of ALC can increase the rate of complications like severe ALC, acute cholangitis and sepsis. The 4th wave of COVID 19 in Northern Italy induced further stress on the healthcare system. In fact, the occurrence of difficult communication and delays in ALC patients transfer between first and second level hospitals lead to the re-emergence of obsolete surgical procedures. In our rural hospital, in fact, a 92 years old patient affected with ALC and several comorbidities was treated with a successful emergency surgical procedure of transperitoneal cholecistostomy in lieu of a radiological transperitoneal approach. Such a choice was dictated by the absence of an interventional radiology unit in our hospital as well as the unavailability of patient transfer to our central referral hub (the hospital of Parma) due to hospital overcrowding secondary to the 4th wave of COVID 19 pandemic.

Otorhinolaryngology tradition is that tonsillectomy (TE) is conducted among children and adolescents for obstructive sleep apnea secondary to adenotonsillar hypertrophy and in adults for chronic disease of the tonsils and adenoids (recurrent tonsillitis). Nevertheless, over the last 50 years, we have observed a decline in TE worldwide. As a result, there is an emerging concern of a correlated possible increased risk of tonsil cancer (TC) and other subtypes of oropharyngeal squamous cell carcinoma. Since the available data on such topics are limited and controversial, our aim was to elucidate the impact of TE on the incidence mainly of TC through a systematic review of the literature and a meta-analysis of the studies. After a thorough search, 7 retrospective studies were considered eligible for review and meta-analysis (MA). At MA, patients with a history of TE seem to show a reduced risk of TC but a higher predisposition for base of tongue (BOT) cancer (p<0.001): however, the elevated heterogeneity of the studies hampers drawing firm and convincing conclusions (statistical inconsistency >95%). In future, randomized control trials will be welcome to elucidate the prophylactic role of TE against TC and its real impact on BOT cancer.

BACKGROUND: The treatment of synchronous pyogenic liver abscess (PLA) and acute cholecystitis (AC) may be challenging. Moreover, because of the similarity of symptoms and the suboptimal accuracy of ultrasound (US), PLA(s) may be undetected, unless a computer tomography (CT) scan is performed. The aims of this study were (1) to evaluate the results of emergency cholecystostomy (CS) and late laparoscopic cholecystectomy (LC) in such a population and (2) to identify the criteria for selecting patients with AC and a high risk of having synchronous PLA(s) for referral for a CT scan. METHODS: A retrospective analysis of the outcome of 12 patients with AC and PLA(s) treated by emergency CS followed by delayed LC from January 1996 through May 2010 at a tertiary-care university hospital was performed. Clinical, laboratory, and radiological data of patients with synchronous AC and PLA(s) are compared with those of 66 patients with "simple" AC. RESULTS: The association of age >55 years, temperature >38°C, WBC count >12,000/ml, and ASAT >50 UI/l and/or ALAT >75 UI/l allows for the selection of patients at high risk of PLA to undergo a CT scan (sensitivity: 100%; specificity: 86%). All treated patients had a sudden improvement within 24 h following CS. PLA was treated in 10/12 patients (83%). Hospital stay lasted 21.5 ± 3.5 days. Ten patients underwent elective LC 12 ± 4 weeks after CS with no conversion and 30% perioperative morbidity. Operating time was 91 min. Hospital stay was 1.7 days [7 patients (70%) underwent surgery as an outpatient]. CONCLUSIONS: A simple algorithm is presented for the selection of patients with AC to undergo a CT scan to identify synchronous PLA. Emergency CS followed by delayed LC is a viable, first-line treatment option for synchronous PLA and AC.

BACKGROUND: In patients presenting with acute diverticulitis (AD) and signs of acute peritonitis, the presence of extradigestive air (EDA) on a computer tomography (CT) scan is often considered to indicate the need for emergency surgery. Although the traditional management of "perforated" AD is open sigmoidectomy, more recently, laparoscopic drainage/lavage (usually followed by delayed elective sigmoidectomy) has been reported. The aim of this retrospective study is to evaluate the results of nonoperative management of emergency patients presenting with AD and EDA. METHODS: The outcomes of 39 consecutive hemodynamically stable patients (23 men, mean age = 54.7 years) who were admitted with AD and EDA and were managed nonoperatively (antibiotic and supportive treatment) at a tertiary-care university hospital between January 2001 and June 2010 were retrospectively collected and analyzed. These included morbidity (Clavien-Dindo) and treatment failure (need for emergency surgery or death). A univariate analysis of clinical, radiological, and laboratory criteria with respect to treatment failure was performed. Results of delayed elective laparoscopic sigmoidectomy were also analyzed. RESULTS: There was no mortality. Thirty-six of the 39 patients (92.3%) did not need surgery (7 patients required CT-guided abscess drainage). Mean hospital stay was 8.1 days. Duration of symptoms, previous antibiotic administration, severe sepsis, PCR level, WBC concentration, and the presence of abdominal collection were associated with treatment failure, whereas "distant" location of EDA and free abdominal fluid were not. Five patients had recurrence of AD and were treated medically. Seventeen patients (47.2%) underwent elective laparoscopic sigmoidectomy for which mean operative time was 246 min (range = 100-450) and the conversion rate was 11.8%. Mortality was nil and the morbidity rate was 41.2%. Mean postoperative stay was 7.1 days (range = 4-23). CONCLUSIONS: Nonoperative management is a viable option in most emergency patients presenting with AD and EDA, even in the presence of symptoms of peritonitis or altered laboratory tests. Delayed laparoscopic sigmoidectomy may be useless in certain cases and its results poorer than expected.

Amyand's hernia (AH) is a rare condition in which the appendix is found in the sac of an inguinal hernia. It occurs in only 1% of adult inguinal hernias. The herniated appendix can occasionally range varying degrees of acute inflammation up to neoplastic transformation. An appendiceal tumor can be rarely described inside the AH sac. We describe a case of gangrenous appendicitis in AH and offer a review of the literature on AH when presenting with appendicitis associated with appendiceal cancer. As of 2022, only nine cases of AH presenting with appendicitis associated with appendiceal cancer have been reported by the pertinent literature. In order of decreasing frequency, AH, AH-related appendicitis and AH-related appendicitis associated with appendiceal cancer are three rare conditions. Particular attention should be kept in each situation as diagnosis is achieved postoperatively most of the times.

BACKGROUND AND AIM: Primary colonic leiomyosarcoma (cLMS) is a rare malignancy of muscularis mucosae or muscularis propria showing highly aggressive behaviour and poor prognosis. To date, making a preoperative diagnosis and performing the most appropriate treatment represent laborious tasks for the clinicians. On the one hand, in fact, cLMS diagnosis is often difficult to achieve preoperatively because of the low specificity of clinical, radiological and bioptical features: for these motives, the diagnosis is usually obtained at postoperative histology/immune-histochemistry. On the other hand, although surgery represents the mainstay of multi-modal treatment, in the current era of minimally invasive surgery the optimal approach to cLMS is debated: in the absence of a standardized and unanimous algorithm, in fact, laparoscopy is usually proposed for small tumors, whereas laparotomy for masses exceeding 4 cm in diameter. Our aim was to elucidate such two aspects by reporting our experience. METHODS: We present the case of a 51-year-old man affected with a 6-cm LMS of the sigmoid colon. RESULTS: Preoperative diagnosis was achieved through a preoperative echo-endoscopic biopsy. The lesion was successfully and safely managed by laparoscopic surgery. CONCLUSIONS: Our case suggests that a preoperative diagnosis of cLMS is possible in an appropriate setting. Moreover, laparoscopy seems to be a safe and successful approach to resect cancers even larger than the common 4 centimetres proposed by the current literature.

BACKGROUND AND AIM: In middle-aged men, omental torsion (OT) can be a cause of acute abdomen.The right side of the omentum is longer, heavier and more mobile than the left one and, as a consequence, it can twist more easily on its vascular axis. Consequently, OT localization in the lower right quadrant is more frequent, and therefore it can mimic acute appendicitis clinical onset.In most cases, OT is defined as "primary" in the absence of any other underlying pathologies, or, rarely, "secondary", when caused by other intra-abdominal diseases such as inguinal hernia, tumors, cysts or post-surgical scarring. To date, clinical diagnosis of OT still remains a challenging one in a preoperative setting and most cases are diagnosed intraoperatively. If diagnosis is correctly achieved preoperatively by adequate imaging examinations, most patients presenting with OT do not undergo surgery anymore. Such considerations gain importance at the time of COVID 19 pandemic, where a conservative management and an early discharge may be preferred owing to in-hospital morbidity after abdominal surgery whenever surgery may be avoided. METHODS AND RESULTS: We present a case of an OT successfully treated in a non-operative manner during COVID-19 outbreak in Norhern Italy and offer a review of the literature that supports such a clinical attitude. Conclusions: OT preoperative diagnosis is challenging and is usually achieved by abdominal CT-scan. The suggested OT initial management is conservative, leaving a surgical approach, preferably by laparoscopy, for the 15% of cases not improving with a non-surgical approach.

Introduction: Intussusception represents a rare form of bowel obstruction in the adult, which is defined as the telescoping of a proximal segment of the gastrointestinal tract into the lumen of the adjacent distal segment of the GI tract Case Report: We report the case of a 50-year-old woman was admitted in our hospital with acute bowel obstruction. CT showed intestinal occlusion secondary to intussusception. the patient underwent emergency surgery. Surgery confirmed intussusception at the level of the distal ileum (about 30 cm from the ileocecal valve) due to a 3-4 oval mass of hard consistency that appeared to be suspicious for GIST. Was performed a resection of the ileal segment involved associated with oncologically radical lymphadenectomy. The histological examination reported benign ileal mesenchymal neoformation compatible with inflammatory fibroid polyp. Patient had a regular course Discussion: In adults, 90% of invaginations manifest as a result of an organic lesion caused by benign or malignant tumors. The clinical presentation in adults is generally chronic or nonspecific. The emergence of acute symptoms due to complete intestinal obstruction occours in fewer than 20% of patients. Abdominal computed tomography (CT) is the most sensitive radiologic method to confirm intussusception. As many cases are secondary to organic pathologies with malignant potential, surgical resection of the affected bowel segment with oncological procedures is the primary method of treatment Conclusion: Due to the fact that adult intussusception is often frequently associated with organic lesions, surgical intervention is necessary. Treatment usually requires formal resection of the involved bowel segment. (www.actabiomedica.it).

BACKGROUND/AIM: Liquid biopsy (LB) is a promising non-invasive tool to detect cancer. Over the last few years, exosomes recruited from LB have attracted the attention of researchers for their involvement in cancer. We focused on the role of LB exosomes in gastric cancer (GC). MATERIALS AND METHODS: We investigated the world literature on exosome-encapsulated functional biomarkers (non-coding RNAs and DNAs) taken from GC patients' LBs. Only the studies exploring serum, intraperitoneal fluid or gastric lavage were included. RESULTS: As of 2022, fifty articles with an overall count of 3552 GC patients were investigated. Given the statistically significant associations with the clinicopathological categories of tumor depth, lymph node metastasis, staging class and tumor size, most exosome-mediated microRNAs, long non-coding RNAs and circular RNAs proved to exert a potentially important bioclinical role in terms of diagnosis, screening, prognosis and therapeutic targets. CONCLUSION: In the future, resorting to exosomal biomarkers taken from LB of affected patients could revolutionize the non-invasive fight against GC.
