RESUMEN
Background: Intimal sarcomas are rare malignant mesenchymal tumors arising from the heart and large blood vessels. Their intraluminal growth leads to vascular obstructive symptoms and peripheral neoplastic embolization. Direct infiltration of the lungs or metastases to the pulmonary system, occur in 40% of cases and extrathoracic spread is frequent, also in presentation. Intussusception is an unusual event in adults, accounting for <5% of bowel obstructions. In most cases it is caused by a malignancy and requires surgical resection. Case Presentation: We describe a rare case of a 50-year-old man suffering of bowel obstruction due to intussusception sustained by a small bowel metastasis of a primary cardiac intimal sarcoma. One year and a half before the onset of abdominal symptoms, a grade II intimal sarcoma was removed from his left atrium and consequently he followed a chemotherapy protocol. Four months later a CT scan revealed local recurrence. Eighteen months after heart surgery he referred to the ER with abdominal pain. CT scan showed an ileal intussusception and the patient was scheduled for surgery. A tract of 10 cm ileus was removed containing an intramural polypoid solid mass. Histological analyses revealed a grade II intimal sarcoma consistent with his first diagnosis. Conclusion: Primary heart tumors are late found and often partially resected, therefore metastatic pathways are to be expected. Adult small bowel intussusception is a rare event and caused by a malignancy in one third of cases. Therefore, our recommendation is to always resect the tract involved in order to perform a proper diagnosis.
RESUMEN
BACKGROUND: Several studies have shown the safety, feasibility and oncologic adequacy of robotic right hemicolectomy (RRH). Laparoscopic right hemicolectomy (LRH) is considered technically challenging. Robotic surgery has been introduced to overcome this technical limitation, but it is related to high costs. To maximize the benefits of such surgery, only selected patients are candidates for this technique. In addition, due to progressive aging of the population, an increasing number of minimally invasive procedures are performed on elderly patients with severe comorbidities, who are usually more prone to post-operative complications. AIM: To investigate the outcomes of RRH vs LRH with regard to age and comorbidities. METHODS: We retrospectively analyzed 123 minimally invasive procedures (68 LRHs vs 55 RRHs) for right colon cancer or endoscopically unresectable adenoma performed in our Center from January 2014 until September 2019. The surgical procedures were performed according to standardized techniques. The primary clinical outcome of the study was the length of hospital stay (LOS) measured in days. Secondary outcomes were time to first flatus (TFF) and time to first stool evacuation. The robotic technique was considered the exposure and the laparoscopic technique was considered the control. Routine demographic variables were obtained, including age at time of surgery and gender. Body mass index and American Society of Anesthesiologists physical status were registered. The age-adjusted Charlson Comorbidity Index (ACCI) was calculated; the tumor-node-metastasis system, intra-operative variables and post-operative complications were recorded. Post-operative follow-up was 180 d. RESULTS: LOS, TFF, and time to first stool were significantly shorter in the robotic group: Median 6 [interquartile range (IQR) 5-8] vs 7 (IQR 6-10.5) d, P = 0.028; median 2 (IQR 1-3) vs 3 (IQR 2-4) d, P < 0.001; median 4 (IQR 3-5) vs 5 (IQR 4-6.5) d, P = 0.005, respectively. Following multivariable analysis, the robotic technique was confirmed to be predictive of significantly shorter hospitalization and faster restoration of bowel function; in addition the dichotomous variables of age over 75 years and ACCI more than 7 were significant predictors of hospital stay. No outcomes were significantly associated with Clavien-Dindo grading. Sub-group analysis demonstrated that patients aged over 75 years had a longer LOS (median 6 -IQR 5-8- vs 7 -IQR 6-12- d, P = 0.013) and later TFF (median 2 -IQR 1-3- vs 3 -IQR 2-4- d, P = 0.008), while patients with ACCI more than 7 were only associated with a prolonged hospital stay (median 7 -IQR 5-8- vs 7 -IQR 6-14.5- d, P = 0.036). CONCLUSION: RRH is related to shorter LOS when compared with the laparoscopic approach, but older age and several comorbidities tend to reduce its benefits.
RESUMEN
BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are a group of rare tumors that account for 2% of all pancreatic malignancies, even though their incidence has been increasing over the past 20 years. Most PNETs are sporadic and tend to affect older individuals. Differently from functional tumors, which present with symptoms resulting from the specific hormone being elaborated, non-functioning pancreatic neuroendocrine tumors (NF-PNETs) typically present with symptoms related to local mass effect or metastatic disease. Today, due to the increasing use of abdominal imaging, NFPNETs are frequently discovered incidentally. CASE REPORT: A 32-year-old woman was admitted to our emergency department for worsening upper abdominal pain radiating to the back. Shortly after the admission, shock and peritoneal signs developed. An abdominal computerized tomography scan showed a solid mass (9 x 12 cm) of the pancreatic tail with severe hemoperitomeum. Exploratory laparotomy and subsequent distal splenopancreasectomy were performed for a bleeding tumor. Histopathological report showed a neuroendocrine, well differentiated tumor (G1). The postoperative course was uneventful and the patient was successfully discharged on 10th postoperative day. CONCLUSION: Spontaneous rupture of solid neuroendocrine neoplasms of the pancreas can cause acute abdomen with potentially devastating effects. KEY WORDS: Abdominal pain, acute abdomen, Hemorrhagic shock, Pancreatic neuroendocrine tumor.

BACKGROUND: Patterns of white blood cells differential count with low lymphocyte number have been associated with poor outcome following sepsis, burns and trauma. Lymphocytopenia, measured preoperatively or in response to surgical stress, may affect complications after bowel resection. METHODS: Clinical characteristics and white blood cells differential count values, measured both pre- and post-operatively of a cohort of patients submitted to intestinal resection and anastomosis from June 2014 to June 2017 in our General Surgery Division, were retrospectively analyzed. Multivariate logistic regression was used to determine the dependence of mortality and postoperative complications from the clinical characteristics of patients and white blood cells differential count values. RESULTS: A total of 301 consecutive patients were studied; 165 (54.8%) were male; mean age was 70 years. Overall, the rate of in-hospital 30-day mortality was 4%. Post-operative morbidity was observed in 124 (41.2%). On multivariate analysis, age adjusted Charlson Comorbidity Index, low preoperatively lymphocyte count, high preoperative monocyte count, high postoperative neutrophil count and anastomotic leak were independently associated with increased in-hospital mortality. Preoperative lymphocytopenia and rectal resection were independently associated with high morbidity rate, while low postoperative lymphocyte count was associated with an increased risk of anastomotic leak. CONCLUSIONS: Perioperative lymphocytopenia is associated with 30-days mortality, severe complications and anastomotic leak after bowel resection surgery. These routinely available laboratory data could help to identify patients at high-risk for developing complications.
RESUMEN
BACKGROUND: Hepatocellular carcinoma (HCC) accounts for 5-6% of all human cancers. Considering the extrahepatic metastasis, the main organs involved are lymphnodes, lung, bone and adrenal gland. Usually colon metastasis is very rare, especially on the left sided colon. CASE SUMMARY: We report a case of a 70 years-old man hepatitis B carrier with HCC treated four times with trans-arterial chemoembolization, presented to our surgical department complaining of gastrointestinal bleeding. A colonoscopy revealed a mass of 4 cm of the sigmoid colon with signs of bleeding. The computed tomography showed a mass originated from the sigmoid colon of 3.5 cm, and the presence of HCC in segment VI and VII, without portal vein thrombosis. Due to the large size of the mass and the active bleeding, the patient underwent a left colectomy. The postoperative period was uneventful, and the patient was discharged in fifth post-operative day. Histological examination revealed that the neoplasm was characterized by a diffuse proliferation of epithelial cells with an hepatoid differentiation. So, the presence of a history of HCC of the liver and the histopathological features supported the diagnosis of metastasis from the liver. CONCLUSION: Although rare, colon metastasis from an HCC can be left-sided and can present with acute bleeding.
RESUMEN
Anal stenosis is a fibrous narrowing of the anal channel. It develops, in most cases, in the aftermath of proctologic surgical procedures with extensive anoderm excision or in the presence of chronic anal inflammation in patients with Crohn Disease. However rare, this condition is thoroughly debilitating for the patients. Symptoms include constipation, pain and bleeding with defecation and a reduction of the caliber of stools. Diagnosis is essentially clinical. Prevention of postsurgical stenosis is based on a scrupulous surgical technique and on an extensive and carefully- planned follow up. Treatment is based on an initially conservative approach with regularization of stool transit through hydration, dietary fibers and bulk-forming laxatives. The role of mechanical dilatation in the treatment of AS is still debated. For severe cases and cases that are not responsive to conservative treatment we must resort to surgery. Surgical approach is tailored on the severity, position and extension. The most severe cases require anoplasty procedures with mucosal or anal flaps. KEY WORDS: Anal stenosis, Anal stricture,Proctology.

Giant condyloma acuminatum (GCA) is a rare cauliflower-like lesion, also known as Buschke-L ewenstein tumor (BLT). Although characterized by benign histological features, the local behavior of GCA is extremely aggressive, showing progressive infiltration of the surrounding structures leading to tissue destruction by compression. As the correlation between HPV and GCA development grew stronger, the majority of the Authors came to the conclusion that HPV can not only cause CA but, associated with particular risk factors, it can lead to much more serious conditions such as BLT. Since the treatment of GCA is still not yet standardized, a very accurate pre-operative analysis of the lesions is required to plan the most suitable treatment approach. Based on current knowledge, macroscopic evaluation of local tumor invasion and extensive radical resection appear to be the only valid therapeutic approach, due to its association with longterm survival and minimal recurrence. Looking forward for new techniques and new tissue sparing treatments, at the moment, GCA can be safely treated with radical excision without immediate tissue reconstruction; long-term complications, such as stricture and stenosis, can be prevented by adequate wound healing and by a particularly intense and long- term follow-up program. KEY WORDS: Anus, Giant condyloma acuminatum.

BACKGROUND: Pancreatic duct disruption is a challenging condition leading to pancreatic juice leakage and consequently to pancreatic fluid collections. The manifestations of pancreatic main duct leak include pseudocysts, walled-off necrosis, pancreatic fistulas, ascites, pleural and pericardial effusions. Pseudocyst formation is the most frequent outcome of a pancreatic duct leak. CASE PRESENTATION: We describe a case of a 64-year old man with large multiple pancreatic cysts discovered for progressive jaundice and significant weight loss in the absence of a previous episode of acute pancreatitis. Computed tomography scan showed lesion with thick enhancing walls. The main cyst dislocated the stomach and the duodenum inducing intra and extrahepatic bile ducts enlargement. Magnetic resonance cholangiopancreatography revealed a communication between the main pancreatic duct and the cystic lesions due to Wirsung duct rupture. Endoscopic ultrasound guided fine needle aspiration cytology did not show neoplastic cells and cyst fluid analysis revealed high amylase concentration. Preoperative exams were suggestive but not conclusive for a benign lesion. Laparotomy was necessary to confirm the presence of large communicating pseudocysts whose drainage was performed by cystogastrostomy. Histology confirmed the inflammatory nature of the cyst wall. Subsequently, the patient had progressive jaundice resolution. CONCLUSION: Pancreatic cystic masses include several pathological entities, ranging from benign to malignant lesions. Rarely pseudocysts present as complex cystic pancreatic lesions with biliary compression in absence of history of acute pancreatitis. We describe the rare case of multiple pancreatic pseudocysts due to Wirsung duct rupture in absence of previous trauma or acute pancreatitis. Magnetic resonance showed the presence of communication with the main pancreatic duct and endoscopic ultrasound fine needle aspiration suggested the benign nature of the lesion.

RESUMEN
BACKGROUND: The diffusion of cross-sectional imaging has recently permitted the detection of an increasing number of incidentalomas localized in the distal pancreas. Currently, there are no studies in the literature exploring the laparoscopic approach as treatment for left-sided pancreatic incidentalomas. METHODS AND RESULTS: We report a series of 20 incidentalomas localized in the body and tail of the pancreas treated with laparoscopic surgery over the period 2010-2014. The incidental masses of our series included a great variety of histotypes and a relevant proportion of malignant lesions. In two cases, the laparoscopic procedures were converted to open surgery. No postoperative death was observed. The postoperative pancreatic fistula rate was 20 %, and the new-onset diabetes rate was 25 %. CONCLUSIONS: Left-sided pancreatic incidentalomas in patients with minor comorbidities can be safely treated with laparoscopic approach. Only clinical trials will confirm whether laparoscopic surgery is an effective treatment for malignant lesions.

Minimally invasive surgery represents the gold standard for the management of deep infiltrating endometriosis (DIE) involving the rectovaginal septum (RVS). This analysis aimed to evaluate the feasibility of robotic-assisted laparoscopy (RAL) and clinical outcomes in terms of long-term complications, pain relief, and recurrence rate for the treatment of DIE of the RVS. A prospective cohort study of robotic procedures was performed between October 2010 and July 2014, including removal of endometriotic nodules from the RVS with rectal shaving alone or in combination with accessory procedures. In all cases, the revised American Society for Reproductive Medicine (rASRM) score for endometriosis was >40 points (stage IV). Twenty-five consecutive patients underwent RAL, with a successful complete nodule debulking by the wall shaving technique. Pathology confirmed the adequacy of the surgical specimen and the median largest endometriotic nodule was of 21 mm (range, 10-60 mm), with free margins in all cases. The median operative time from skin opening to closure was 174 minutes (range, 75-300 minutes), and blood loss was close to 0 mL. The median revised Enzian score for location A (RVS) was 2 (range, 1-3). The most frequent Enzian class was A2B0C0 (48%), followed by A3B0C0 (12%). In 3 cases (12%), partial vaginal resection was required to remove endometriotic nodules of the RVS (1 each in classes A3B0C1FI, A3B0C0FO, and A3B0C0). No intraoperative complications occurred. This series has a median long-term follow up of 22 months (range, 6-50 months) currently available with an optimal operative time, demonstrating good long-term outcomes. Our data support robotics as a safe and attractive alternative for comprehensive surgical treatment of DIE.

Abdominal wall actinomycosis is a rare disease frequently associated with the presence of an intra uterine device. We report on a case of a 47-year-old woman who had used an intrauterine device for many years and had removed it about a month prior to the identification of an abdominal wall abscess caused by Actinomyces israelii. The abscess mimicked a malignancy and the patient underwent a demolitive surgical treatment. The diagnosis was obtained only after histopathological examination. Postoperatively, the patient developed an infection of the wound which was treated with daily medication. The combination of long-term high dose antibiotic therapy with surgery led to successful treatment.
RESUMEN
Ovarian cysts are the most common cause of pelvic masses in women, and in the majority of the cases, women are in their fertile age. Today, the surgical treatment has become more conservative and less invasive; hence, a laparoscopic approach in the presence of benign cysts has become a gold standard. Herein, we report a case of a 21-year-old woman referred to our Surgical Department for an abdominal mass, discovered with a computerised tomographic scan, of 20x10 x 25cm arising from the left ovary, treated with the laparoscopic approach.

Primary tumours of the pleura are commonly divided into two major categories: diffuse and localised. Whereas the diffuse variant is known for its association with asbestos and its poor outcome, the localised one is rare and remains a subject of controversy. Electron microscopy and immunohistochemistry have recently demonstrated that these tumours are of mesenchymal rather than mesothelial origin, and therefore the term "localised mesothelioma" was abandoned. Such tumours are now called solitary fibrous tumours of the pleura (SFTP). The Authors describe a series of 6 cases of benign solitary fibrous tumours of the pleura, surgically treated over the period 1982-2000.

Papillary cystic and solid tumour of the pancreas is a very rare variant form of pancreatic tumour. Such neoplasms have a malignant potential, but their prognosis is good if they are diagnosed early and treated by radical surgical resection. This paper describes a case of a young woman with papillary cystic and solid tumour of the pancreas, localized in the body and tail of the pancreas and treated by distal pancreatectomy. The authors discuss the pathogenesis and the clinical, histological, radiological and surgical features of this tumour.

Enteral feeding by jejunostomy is one of the main surgical procedures used to supply the proteins and calories necessary in the early postoperative period after major surgery of the upper digestive tract. The complications associated with early postoperative enteral feeding may vary from signs of gastrointestinal intolerance such as nausea, emesis, diarrhoea and cramp-like abdominal pain to hypotension and hypovolaemic shock, and also to the development of small bowel ischaemia and necrosis. Ischaemic intestinal involvement with progression towards necrosis is fortunately a rare event. The cause is not well known. A multifactorial pathogenesis of the mucosal damage has been proposed, where hyperosmolarity of feeding and bacterial overgrowth, due to excessive fermentation of carbohydrates, a decreased mesenteric blood flow and a lowering of peristalsis have been adduced as causes of mucosal injury. We report a case of intestinal necrosis following a jejunostomy procedure, which led to ileal resection.
