Hand-Sewn Versus Stapled Small Bowel Anastomoses in Patients With Secondary Mesenteric Ischemia.

INTRODUCTION: Although stapled anastomoses have been widely evaluated in the context of the elective surgery, few reports compared manual with stapled anastomoses in patients undergoing emergency surgery. The aim of this study is to compare the outcome of hand-sewn end-to-end anastomoses with stapled side-to-side and stapled end-to-side anastomoses in patients undergoing small bowel resection for acute mesenteric ischemia secondary to intestinal obstruction. METHODS: From January 2015 to June 2021 all the hemodynamically stable patients undergoing emergency surgery with small bowel resection for intestinal obstruction were enrolled in this study. According to surgical technique in performing anastomosis, the patients were divided into three groups: group 1: hand-sewn end-to-end anastomosis, group 2: stapled end-to-side anastomosis, and group 3: stapled side-to-side anastomosis. RESULTS: Although the anastomosis failure rate was higher in group 3, it was not significantly different between the three groups (P = 0.78: chi-square test). Likewise, no significant differences in the median hospital stay were found between the patients' groups (P = 0.87: Kruskal-Wallis test). The median operating time was similar in patients undergoing stapled anastomoses and was significantly higher in patients undergoing hand-sewn anastomoses (P = 0.0009: Kruskal-Wallis test). CONCLUSIONS: In patients undergoing emergency small bowel resection for complicated intestinal obstruction, a similar outcome in terms of dehiscence rate and hospital stay can be achieved performing stapled or hand-sewn anastomoses, even if restoring the intestinal continuity with stapled technique is associated with lower operating time.

Accuracy of computed tomography in staging acute appendicitis and its impact on surgical outcome and strategy: a multi-center retrospective case-control study.

INTRODUCTION: The aims of this study were to evaluate the concordance between AAST-CT appendicitis grading criteria, first published in 2014, and surgical findings and to assess the impact of CT staging on the choice of surgical approach. METHODS: This was a multi-center retrospective case-control study including 232 consecutive patients undergoing surgery for acute appendicitis and who had undergone preoperative CT evaluation between 1 January 2017 and 1 January 2022. Appendicitis severity was classified in 5 grades. For each degree of severity, the surgical outcome between patients undergoing open and surgical approach was compared. RESULTS: An almost perfect agreement (k = 0.96) was found between CT and surgery in staging acute appendicitis. The vast majority of patients with grade 1 and 2 appendicitis underwent laparoscopic surgical approach and showed low morbidity rate. In patients with grade 3 and 4 appendicitis, laparoscopic approach was adopted in 70% of cases and was associated, if compared to open, with a higher prevalence of postoperative abdominal collections (p = 0.05; fisher's exact test) and a significantly lower prevalence of surgical site infections (p = 0.0007; fisher's exact test). All the patients with grade 5 appendicitis were treated by laparotomy. CONCLUSIONS: AAST-CT appendicitis grading system seems to show a relevant prognostic value and a potential impact on the choice of surgical strategy, directing toward a laparoscopic approach in patients with grade 1 and 2, an initial laparoscopic approach, replaceable by the open one, for grade 3 and 4 and an open approach in patients with grade 5.

Advantages of Damage Control Strategy With Abdominal Negative Pressure and Instillation in Patients With Diffuse Peritonitis From Perforated Diverticular Disease.

Purpose. To evaluate the results of Damage Control Strategy (DCS) in the treatment of generalized peritonitis from perforated diverticular disease in patients with preoperative severe systemic diseases. Methods. All the patients with diffuse peritonitis (Hinchey 3 and 4) and the American Society of Anesthesiologists (ASA) score ≥3 were included and underwent DCS consisting of a 2-step procedure. The first was peritoneal lavage, perforated colon-stapled resection, and temporary abdominal closure with negative pressure wound therapy combined with instillation. The second step, 48 hours later, included the possibility of restoring intestinal continuity basing on local and general patients' conditions. Results. Thirty patients (18 [60%] women and 12 [40%] men, median age 68.5 [range = 35-84] years) were included (18 [60%] ASA III, 11 [36.7%] ASA IV, and 1 [0.03%] ASA V). Seven patients (23.3%) showed sepsis and 1 (3.33%) septic shock. At second surgery, 24 patients (80%) received a colorectal anastomosis and 6 patients (20%) underwent a Hartmann's procedure. Median hospital stay was 18 days (range = 12-62). Postoperative morbidity rate was 23.3% (7/30) and included 1 anastomotic leak treated with Hartmann's procedure. Consequently, at discharge from hospital, 23 patients (76.6%) were free of stoma. Primary fascial closure was possible in all patients. Conclusions. DCS with temporary abdominal closure by negative pressure wound therapy combined with instillation in patients with diffuse peritonitis from complicated diverticulitis could represent a feasible surgical option both in hemodynamically stable and no stable patients, showing encouraging results including a low stoma rate and an acceptable morbidity rate.

Role of tridimensional endoanal ultrasound (3D-EAUS) in the preoperative assessment of perianal sepsis.

PURPOSE: The aim of this study was to evaluate the accuracy of tridimensional endoanal ultrasound (3D-EAUS) in the diagnosis of perianal sepsis comparing the results with the surgical findings, considered as reference standard. METHODS: From January 2009 to January 2013, all the patients referred for the assessment and treatment of perianal sepsis with suspected anorectal origin were enrolled in the study. All patients gave informed written consent. Prior to surgery, all the patients underwent anamnestic evaluation, clinical examination, and unenhanced and H2O2-enhanced 3D-EAUS. Surgery was performed by a colorectal surgeon blinded to the 3D-EAUS results. RESULTS: A total of 212 patients with suspected perianal suppurations were assessed during the study period. In 12 patients, the H2O2-enhanced 3D-EAUS was not performed, and so, they were excluded from the study. Very good agreement between 3D-EAUS and examination under anesthesia (EUA) in the classification of primary fistula tracts (kappa = 0.93) and in the identification of fistula internal opening (kappa = 0.97) was found. There was a good concordance (kappa = 0.71) between 3D-EAUS and surgery in the detection of fistula secondary extensions. The overall sensitivity and specificity of 3D-EAUS in the diagnosis of perianal sepsis were 98.3 and 91.3% respectively. CONCLUSION: 3D-EAUS is a safe and reliable technique in the assessment of perianal sepsis. It may assist the surgeon in delineating the fistula tract anatomy and in determining the origin of sepsis, supporting the preoperative planning of definitive and appropriate surgical therapy.

Sepsis Outcome after Major Abdominal Surgery Does Not Seem to Be Improved by the Use of Pentameric Immunoglobulin IgM: A Single-Center Retrospective Analysis.

BACKGROUND: Sepsis still represents a major public health issue worldwide, and the immune system plays a main role during infections; therefore, its activity is mandatory to resolve this clinical condition. In this report, we aimed to retrospectively verify in a real-life setting the possible usefulness of pentameric IgM plus antibiotics in recovering patients with sepsis after major abdominal surgery. MATERIALS/METHODS: We reviewed, from January 2013 until December 2019, all adult patients admitted to the ICU for sepsis or septic shock (2) after major abdominal surgery. Among these patients, were identified those that, according to legal indication and licenses in Italy, were treated with pentameric IgM plus antibiotics (Group A) or with antibiotics alone (Group B). The following parameters were evaluated: blood gas analysis, lactate, CRP, procalcitonin, endotoxin activity, liver and renal function, coagulation and blood cell count at different time points (every 48 h for at least 7 days). Differences between groups were analyzed using Fisher's exact test or a chi-square test for categorical variables. A Mann-Whitney U test or Kruskal-Wallis test were instead been performed to compare continuous variables. Univariate and multivariate analysis were also performed. RESULTS: Over a period of 30 months, 24 patients were enrolled in Group A and 20 patients in Group B. In those subjects, no statistical differences were found in terms of bacterial or fungal infection isolates, when detected in a blood culture test, or according to inflammatory index, a score, lactate levels and mortality rate. A 48 h response was statistically more frequent in Group B than in Group A, while no differences were found in other clinical and laboratory evaluations. CONCLUSIONS: Based on our results, the use of pentameric IgM does not seem to give any clinical advantages in preventing sepsis after major abdominal surgery.

Usefulness of damage control approach in patients with limited acute mesenteric ischemia: a prospective study of 85 patients.

To evaluate the efficacy of the damage control approach by two-step surgical procedure in not critical patients (without sepsis or septic shock) with peritonitis from limited acute mesenteric ischemia. From April 2013 to April 2020, 85 patients [49 (57.7%) women and 36 (42.3%) men, median age 69.5 (range 38-92)] were enrolled in this study and underwent emergency surgery. After resection of ischemic bowel, basing on the individual decision of the single surgeon, the patients underwent primary end-to-end anastomosis (Group 1) or damage control approach (Group 2) including primary laparotomy with resection of ischemic bowel, temporary abdominal closure and a second-look procedure at 48 h with re-evaluation of bowel vitality. Forty-seven (55.3%) patients underwent one-stage surgical treatment and 38 (44.7%) patients received a two-step procedure. In the latter group, at second exploration, 8 (21%) patients required a further intestinal resection, due to mesenteric ischemia progression. Both anastomosis dehiscence rate and need for ileostomy in Group 1 patients were significantly higher than in Group 2 (23.4% vs 5.3%: p = 0.03 and 19.1% vs 2.6%: p = 0.03; Fisher's exact test). No significative differences in mortality and morbidity rate were found between the two groups. The damage control approach by two-step surgical procedure may represent a valid innovative option in the management of not critical patients with limited acute mesenteric ischemia, achieving a better clinical outcome if compared with surgical treatment by one-step procedure.

Impact of SARS-Cov-2 pandemic on Emergency General Surgery. A single-center observational study.

INTRODUCTION: Several articles have been published on impact COVID-19 infection about reduction of surgical activity. We have focused on the differences between our surgical activity in an Emergency General Surgery department in "Cardarelli" Hospital in Naples. METHODS: This retrospective study compared the patients treated from March 9, 2020 to April 27, 2020 (Italian lockdown time) and the patients treated in the same period of 2019. We recruited 75 patients in Group A (2020) and 165 patients in Group B (2019). RESULTS: There was a reduction in hospitalizations for non-trauma disease (69 in group A and 122 in group B with p: 0.001), a reduction in transfers from other hospitals (2 patients in group A and 17 in group B with p. 0.04) and a reduction in hospitalizations for trauma disease (6 in group A and 43 in group B with p: 0.001). The severity of the disease in 2020 was greater than in the same period in 2019 and there was a higher rate of high-grade complications CONCLUSION: From data analysis, we conclude that there has been a reduction in hospitalizations and surgical interventions in our emergency surgery department. The patients, however, had a much more severe disease that resulted in a greater number of complications in the peri and post-operative time. KEY WORDS: COVID-19, Lockdown, Emergency Surgery, Severity of disease.

Treatment of acute diverticulitis with open abdomen technique.

AIM: The aim of this study is to highlight our experience about the use of open Abdomen's technique as strategy for the management of complicated colon diverticulitis with a delayed anastomosis or colostomy. MATERIALS AND METHODS: Thirty patients, with III and IV Hinchey stage, have been undertaken to a surgical procedure with Open Abdomen technique and application of Ab-thera device. A second surgical look was made after 48-72 hours in order to evaluate the possibility to do an anastomosis or colostomy. RESULTS: No deaths in patients with anastomosis were reported, but one case of leakage at the 8th day and one case of micro pulmonary embolism had been displayed. Elderly patients were discharged between the 15TH /18th day. One patient affected by lymphoma was sent in haematology department for other treatment. DISCUSSION: Today trend is to treat the diverticular disease with colic and paracolic abscess by a medical therapy and percutaneous drainage under CT scan or ultrasound view. With III and IV of Hinchey scale we perform the resection with anastomosis or colostomy. The open abdomen technique allows the surgeons to make the decision of colostomy or anastomosis in the second surgical look at 48-72 hours after the first treatment with irrigation and aspiration during AB-Thera. CONCLUSION: The Open Abdomen technique is a valid therapeutic alternative approach for patients with acute diverticulitis disease in III and IV Hinchey grade. This therapeutic approach gives important advantages in patients with delayed colostomy. KEY WORDS: Diverticulitis, Damage Control Surgery, Open Abdomen.

[Intestinal reconstruction after dehiscence of a jejunal suture in a patient submitted to aorto-enteric fistula repair: a case report]. / Ricostruzione intestinale dopo deiscenza di sutura digiunale in paziente sottoposto a riparazione di fistola aorto-enterica: case report.

Aorto-enteric fistulas are serious complications of aortic surgery that require swift, effective surgical intervention. We report a case of a secondary aortoenteric fistula treated with prosthesis replacement and an intestinal suture subsequently complicated by the dehiscence of the previously constructed anastomosis. We opted for reconstruction re-intervention, closing the intestinal lesion by means of a mechanical suture above the jejunal dehiscence, making a side-to-end jejuno-jejunal Roux anastomosis and an end-to-side anastomosis at the base of the loop. The operation was completed by performing a gastrostomy and transforming the fistula into a jejunostomy. This intervention enabled us to discharge the patient in good general condition after 30 days.

Non-Operative Management of Blunt Liver Trauma: Safety, Efficacy and Complications of a Standardized Treatment Protocol.

OBJECTIVE: To evaluate the safety and effectiveness of NOM (non-operative management) in the treatment of blunt liver trauma, following a standardized treatment protocol. METHODS: All the hemodynamically stable patients with computed tomography (CT) diagnosis of blunt liver trauma underwent NOM. It included strict clinical and laboratory observation, 48-72h contrast enhanced ultrasonography (CEUS) or CT follow-up, a primary angioembolization in case of admission CT evidence of vascular injuries and a secondary angioembolization in presence of vascular injuries signs at follow-up CEUS. RESULTS: 181 patients (85.4%) [55 (30.4%) women and 126 (69.6%) men, median age 39 (range 14-71)] were included. Of these, 63 patients (34.8%) had grade I, 48 patients (26.5%) grade II, 39 patients (21.5%) grade III, 21 patients (11.6%) grade IV and 10 patients (5.5%) grade V liver injuries. The overall success rate of NOM was 96.7% (175/181). There was not significant difference in the success rate between the patients with different liver injuries grade. Morbidity rate was 7.4% (13/175). Major complications (2 bilomas, 1 liver hematoma and 2 liver abscesses) were successfully treated by CEUS or CT guided drainage. Eighteen (18/181) patients (9.9%) underwent angioembolization with successful results. CONCLUSION: Non-operative management of blunt liver trauma represents a safe and effective treatment for both minor and severe injuries, achieving an high success rate and an acceptable morbidity rate. The angiographic study with embolization, although required only in selected cases of vascular injuries, represents a fundamental therapeutic option in a significant percentage of patients.

Damage control surgery for perforated diverticulitis with diffuse peritonitis: saves lives and reduces ostomy.

Introduction: Over the last decade, damage control surgery (DCS) has been emerging as a feasible alternative for the management of patients with abdominal infection and sepsis. So far, there is no consensus about the role of DCS for acute perforated diverticulitis. In this study, we present the outcome of a multi-institutional series of patients presenting with Hinchey's grade III and IV diverticulitis managed by DCS. Methods: All the participating centers were tertiary referral hospitals. A total of 34 patients with perforated diverticulitis treated with DCS during the period 2011-2017 were included in the study. During the first laparotomy, a limited resection of the diseased segment was performed followed by lavage and use of negative pressure wound therapy (NPWT). After 24/48 h of resuscitation, patients returned to the operating room for a second look. Mortality, morbidity, and restoration of bowel continuity were the primary outcomes of the study. Results: There were 15 males (44%) and 19 females (56%) with a mean age of 66.9 years (SD ± 12.7). Mean BMI was 28.42 kg/m2 (SD ± 3.33). Thirteen cases (38%) were Wasvary's modified Hinchey's stage III, and 21 cases (62%) Hinchey's stage IV. Mean Mannheim Peritonitis Index (MPI) was 25.12 (SD ± 6.28). In 22 patients (65%), ASA score was ≥ grade III. Twenty-four patients (71%) had restoration of bowel continuity, while 10 (29%) patients had an end colostomy (Hartmann's procedure). Three of these patients received a temporary loop ileostomy. One patient had an anastomotic leak. Mortality rate was 12%. Mean length of hospital stay was 21.9 days. At multivariate analysis, male gender (p = 0.010) and MPI (p = 0.034) correlated with a high percentage of Hartmann's procedures. Conclusion: DCS is a feasible procedure for patients with generalized peritonitis secondary to perforated diverticulitis, and it appears to be related to a higher rate of bowel reconstruction. Due to the open abdomen, stay in ICU with prolonged mechanical ventilation is required, but these aggressive measures may be needed by most patients undergoing surgery for perforated diverticulitis, whatever the procedure is done.

Clinical symptoms of intestinal vascular disorders.

Despite advances made in the diagnostic and therapeutic field, acute intestinal ischemia remains a highly lethal condition. This is related to the variability of symptoms and the absence of typical laboratory alterations in early stage.

[Our experience in the management of patients with Mirizzi syndrome]. / Orlentamenti attuali nel trattamento della sindrome di Mirizzi. Nostra esperienza.

The authors report their experience in the management of patients with Mirizzi Syndrome (MS) admitted, over a period of 15 years, at the General Surgery of Emergency Department of Cardarelli Hospital, Naples, Italy. All patients were admitted and surgically treated in emergency save for one. Out of 12 patients, cholecystectomy was performed in 7 cases. In others 5 patients, with cholecystocholedochal fistula, cholecystectomy with positionig of T-Tube was performed in 4 cases (MS-II); finally, 1 patient with MS type III undewrwent choledochojejunostomy. According to literature, the diagnostic protocol included abdominal ultrasonography and CT scan of the abdomen for all patients; in one case, a cholangio-MRI was performed to clarify the diagnosis. The preoperative diagnosis is essential to reduce risk of iatrogenic injuries. The cholangio-MRI, used to this extent, clarifies the site of obstruction, shows the anatomy of the biliary tree and allows to make all the possible differential diagnoses in order to exclude the presence of biliary tumors before surgery. The intraoperative cholangiography remains mandatory to clarify the anatomy of the biliary tree. In the cases we have treated, ERCP was never performed. We believe that ERCP has limited indications and unsatisfactory outcomes for both diagnosis and treatment of MS. Pathological examination of the fresh-frozen surgical specimens was always performed intraoperatively to exclude the presence of concomitant cancer of the gallbladder. The traditional treatment of patients with MS is surgery, as confirmed by our experience. We perform cholecystectomy for MS type I and cholecystectomy with direct repair of the biliary fistula over aT tube for MS type II. Patients with MS type III usually undergo a tailored operation based on the intraoperative findings, while choledochojejunostomy is mandatory for patients with MS type IV. Laparoscopic surgery is indicated only for MS type I and II. It seems to carry a higher risk for the patient and we do not use this approach in the emergency settings.

Negative pressure therapy alone or with irrigation in the management of severe peritonitis.

BACKGROUND: Ogilvie was the first to publish on open abdomen (OA) for the treatment of the damages caused by penetrating abdominal wounds in war events. Research improved those devices that allow a controlled, homogeneous and continuous extraction of contaminated fluids from all abdominal recesses, which are nowadays the base of the "Open Abdomen" technique. MATERIALS AND METHODS: From August 2012 to February 2016 at the Department of Emergency Surgery of Cardarelli Hospital in Naples, 40 patients affected by Severe Peritonitis have been treated with OA technique. 13 (32,5%) were treated with only the suction-drainage system, 27 patients (67,5%) were treated with suction drainage and irrigation system. Abthera® device was used in all patients. RESULTS: The duration of treatment was 15 days in the first group, with 7 device's substitutions, while in the second group it was about 10 days with 4 substitutions At the end of the procedure we were able to perform primary fascia closure in 7 cases (53,8%) in the first group and in 23 cases (85.2%) in the second group. 4 patients (30,8%) died in the first group, and 7 (26%) in the second. CONCLUSION: The suction/irrigation method seems to be appropriate to use in case of a surgical emergency that causes severe peritonitis. It is associated not only with lower death rates but also with better parameters, that are more frequently worse during prolonged treatments. Irrigation of abdominal cavity causes also less retraction of fascia recti which leads to a higher rate of direct fascia closure. Key Words: Emergency surgery, Irrigation, Open abdomen, Peritonitis.

[Mainly abdominal "complex" polytrauma. Considerations on surgical strategy and clinical case report]. / Politraumatismo "complesso" a prevalenza addominale. Considerazioni sulla strategia chirurgica e presentazione di un caso clinico.

The Authors want to present un uncommon case of polytrauma managed with surgical treatment at the Trauma Center of the A. Cardarelli Hospital in Naples. Chest, abdomen, pelvis, and left lower limb have been severely injured. This case is so interesting because of the rareness of some lesions (i.e. diaphragm rupture) and the numerous lesions of internal organs (i.e. lungs, spleen, liver, pancreas, mesenterium) and of the bones (i.e. thigh-bone and pelvis). A very good outcome has been obtained for survival as well as for functionality and quality of life since we have strictly applied the rules for the management of the "complex" polytrauma.

Primary anastomosis in emergency surgery of left colon cancer.

INTRODUCTION: Colorectal cancers are second leading cause of death in Western countries. There are about 1500 deaths per year in Italy due to colorectal cancer in both sex 1. MATERIALS AND METHODS: 224 patients, 127 women (56.7%) and 97 men (43.3%) underwent colorectal resection with primary anastomosis (RPA) in emergency due to occlusive left colon cancer between 2010 and 2016. Patients had a mean age of 67.2 year a BMI inferior than 30 Kg/m2 in 215 cases (96%) and a history of cardiovascular disease in 112 (50%) cases. RESULTS: All patients with a regular postoperative course have had no more than 10 days of hospitalization except for four who suffered postoperative ileus which solved after no more 15 days. We have had 24 (10.7%) cases of morbidity for generic causes and 12 cases (5.4%) of post-operative complications. Pneumonia, which occurred in 12 cases (5.4%), was the most frequent. CONCLUSION: The ideal technique does not actually exist. RPA is, when feasible, advisable for occlusive neoplastic cases, ensuring a low percentage of morbidity and mortality and respecting patient's quality of life.

International consensus conference on open abdomen in trauma.

BACKGROUND: A part of damage-control laparotomy is to leave the fascial edges and the skin open to avoid abdominal compartment syndrome and allow further explorations. This condition, known as open abdomen (OA), although effective, is associated with severe complications. Our aim was to develop evidence-based recommendations to define indications for OA, techniques for temporary abdominal closure, management of enteric fistulas, and methods of definitive wall closure. METHODS: The literature from 1990 to 2014 was systematically screened according to PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-analyses] protocol. Seventy-six articles were reviewed by a panel of experts to assign grade of recommendations (GoR) and level of evidence (LoE) using the GRADE [Grading of Recommendations Assessment, Development, and Evaluation] system, and an international consensus conference was held. RESULTS: OA in trauma is indicated at the end of damage-control laparotomy, in the presence of visceral swelling, for a second look in vascular injuries or gross contamination, in the case of abdominal wall loss, and if medical treatment of abdominal compartment syndrome has failed (GoR B, LoE II). Negative-pressure wound therapy is the recommended temporary abdominal closure technique to drain peritoneal fluid, improve nursing, and prevent fascial retraction (GoR B, LoE I). Lack of OA closure within 8 days (GoR C, LoE II), bowel injuries, high-volume replacement, and use of polypropylene mesh over the bowel (GoR C, LoE I) are risk factors for frozen abdomen and fistula formation. Negative-pressure wound therapy allows to isolate the fistula and protect the surrounding tissues from spillage until granulation (GoR C, LoE II). Correction of fistula is performed after 6 months to 12 months. Definitive closure of OA has to be obtained early (GoR C, LoE I) with direct suture, traction devices, component separation with or without mesh. Biologic meshes are an option for wall reinforcement if bacterial contamination is present (GoR C, LoE II). CONCLUSION: OA and negative-pressure techniques improve the care of trauma patients, but closure must be achieved early to avoid complications.

[The congenital cystic dilatation of the liver and bile ducts (CDB): our experience]. / La dilatazione congenita delle vie biliari: la nostra esperienza.

The congenital cystic dilatation of the liver and bile ducts (CDB) is a very uncommon disease. It often appears in females and most frequently in paediatric patients. Its etiopathogenesis is not yet completely defined. Its evolution includes, together with several complications, the malignant transformation. The Authors present the outcomes of their experience based on a series of 5 patients observed from 1991 till today. Apart from the rarity of this disease, their series is so interesting because 4 out of 5 are adult patients and the fifth one is over 15. In addition, differentiating from the literature trend, the group included only male patients. Are also discussed the most important aspects referring to nosology, epidemiology, etiopathogenesis, clinical pattern and its evolution of CDB, looking over a wide review too. The Authors extensively examine the diagnostic problems; owing to that the patients were observed in the period 1991-1999 it is necessary to clarify that some imaging methods, i.e. CSTscan and the bile duct MNR, were not yet introduced. The surgical treatment has been investigated as well, developed during its historical evolution until nowadays and our solutions for the 5 cases have been presented and discussed. In their series the Authors haven't ever observed during hospitalisation a malignant transformation.

[Conservative treatment of the digestive fistulas: personal experience]. / Trattamento conservativo delle fistole digestive: nostra esperienza.

OBJECTIVE: The authors, thanks to experience obtained in an Unit for the treatment of digestive fistulas, discuss the possibility of a conservative treatment for the anastomotic fistulas. MATERIAL AND METHODS: From 2000 to 2003 were treated thirty-five patients with post-anastomotic gastroenteric fistulas marked according to their localization, way end output (51.5% high, 42.8% moderate and 5.7% low). The treatment is based on an aspiration system, sometimes integrated with an irrigation system. A semi-permeable barrier was created over the fistula by vacuum packing a synthetic, hydrophobic, polymer covered with a self-adherent surgical sheet. This system create a vacuum chamber equipped with a subathmospheric pressures between 262.2 and 337.5 mmHg (350-450 mmbar), integrated with a continuous irrigation using antibiotic solutions or 3% lactic acid. RESULTS: The AA. obtained the resolution in 30 patients (85.7%), 3 patients needs the surgery (8.6%), 2 died, one for sepsis and the other one for malnutrition. The mean time for the closure was 45 days (from 20 to 90). A part of digestive external fistulas goes to spontaneous resolution so comes the idea that the creation of particular condition is the basis of their closure.

Unusual bleeding of a giant cell fibroblastoma: a soft tissue sarcoma of the skin mimicking metastatic melanoma.

A 56 year-old man presented to the emergency department after a spontaneous bleeding of a giant mass located on the right axilla. Clinical diagnosis was recurrent hemorrhagic nodular melanoma. Ten months previously a malignant melanoma had been removed from the dorsum by radical excision and surgical margins had been disease-free (MM: Breslow IV, Clark IV, lung and lynphnode metastases). The patient required immediate emergency surgical intervention to prevent death by hemorrhagic shock. The tumor was bleeding and the patient required a transfusion. Subjective symptoms included pain in palpation and spontaneous hemorrhage, poor general appearance, pale skin, BP 80/40 mmHg, HR 100/min with overall symptoms of hypovolemic shock. At the time of surgery, radical tumor excision was performed with an approximately 3 cm circumferential gross tumor free margin. The resultant defect was reconstructed by pectoral rotation fascio-cutaneous flap. The histological diagnosis demonstrated an undifferentiated high-grade pleomorphic sarcoma with microscopic tumor free margins.
