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.

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.

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.

C-reactive protein but not procalcitonin may predict antibiotic response and outcome in infections following major abdominal surgery

We aimed to evaluate the usefulness of C-reactive protein (CRP) and procalcitonin (PCT) as markers of infection, sepsis and as predictors of antibiotic response after non-emergency major abdominal surgery. We enrolled, from June 2015 to June 2019, all patients who underwent surgery due to abdominal infection (peritoneal abscess, peritonitis) or having sepsis episode after surgical procedures (i.e. hepatectomy, bowel perforation, pancreaticoduodenectomy (PD), segmental resection of the duodenum (SRD) or biliary reconstruction in a Tertiary Care Hospital. Serum CRP (cut-off value < 5 mg/L) and PCT (cut-off value < 0.1mcg/L) were measured in the day when fever was present or within 24 h after abdominal surgery. Both markers were assessed every 48 h to follow-up antibiotic response and disease evolution up to disease resolution. We enrolled a total of 260 patients underwent non-emergency major abdominal surgery and being infected or developing infection after surgical procedure with one or more microbes (55% mixed Gram-negative infection including Klebsiella KPC, 35% Gram-positive infection, 10% with Candida infection), 58% of patients had ICU admission for at least 96 h, 42% of patients had fast track ICU (48 h). In our group of patients, we found that PCT had a trend to increase after surgical procedure; particularly, those undergoing liver surgery had higher PCT than those underwent different abdominal surgery (U Mann–Whitney p < 0.05). CRP rapidly increase after surgery in those developing infection and showed a statistical significant decrease within 48 h in those subject being responsive to antibiotic treatment and having a clinical response within 10 days independently form the pathogens (bacterial or fungal). Further we found that those having CRP higher than 250 mg/L had a reduced percentage of success treatment at 10 days compared to those < 250 mg/mL (U Mann–Whitney p < 0.05). PCT did not show any variation according to treatment response. CRP in our cohort seems to be a useful marker to predict antibiotic response in those undergoing non-emergency abdominal surgery, while PCT seem to be increased in those having major liver surgery, probably due to hepatic production of cytokines.

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.

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.

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.

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.

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.

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.

Unexpected histopathologic result of a wide surgical excision of a bleeding lesion of the skin: a case of Merkel cell carcinoma of the leg

BACKGROUND

Merkel cell Carcinoma is a very rare primary cutaneous tumor that often looks like an innocuous and asymptomatic nodule or plaque of the skin, but with a very fast growing. It is also called neuroendocrine carcinoma of the skin or trabecular cancer. The main treatment is based on a local excision followed by radiotherapy or chemotherapy. The most common site of presentation of this lesion is head and neck (40-60%.) and it often occur in older men with immunological system dysfunction like HIV patients, cancer, severe infections and immunosuppression for transplantation.

METHODS

The authors report a case of a bleeding Merkel Cell Carcinoma of the right leg in a 83 years old man with HCV infection, chronic kidney disease and diabetes mellitus type 2 that required local excision.

RESULTS

Lesion was entirely removed and then patient was sent to oncologists. After two months from surgical excision, healing process is regular and without complications.

CONCLUSIONS

This type of tumor can be misdiagnosed and, if bleeding, it can represent a serious surgical emergency.

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.

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.

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.

Penetrating cardiac injuries. Two case reports

INTRODUCTION

Penetrating cardiac injuries is still a diagnostic problem at this time. Their management requires immediate surgical intervention and excellent surgical critical care postoperatively.

PRESENTATION OF CASES

A 15-year old male patient was stabbed with a knife to the right chest. The chest radiograph showed an haemothorax and the angiography showed an intercostals artery and a right auricle injury. After an emergency operation the patient was released home in good condition after the toracotomy had healed. A 19-year old male patient was stabbed with a knife to the chest more than once. By a left toracotomy we sutured the lesion of the left ventricle with multiple single stitch in non-absorbable suture, we covered the suture with a sealant. The patient released home in 24 days.

DISCUSSION

Penetrating cardiac injuries is one of the leading cause of death from urban violence. To evaluate a thoracic trauma with cardiac injury it's clear the use of thorax X-ray and multislice angio-Tc scan. Echocardiography has clearly emerged for the diagnosis in patients haemodynamically stable. When the patient is haemodynamically unstable the emergency thoracotomy is mandatory.

CONCLUSION

Despite the high mortality of penetrating cardiac injuries new surgical and radiological tecniques may help surgeon to save this patients.

Severe spontaneous properitoneal hemorrhage following ventral hernia repair caused by viral infection: report of a case

The authors report a case of severe spontaneous hemorrhage in a patient who underwent surgical repair of an upper umbilical ventral hernia with placement of a polypropylene mesh. On the third postoperative day the patient experienced bleeding in the properitoneal space (above and below the mesh), which spread up to and along the retroperitoneal area, causing severe hypovolemic shock. Postoperative investigations finally identified a virus as the cause of the complication.

[Intestinal reconstruction after dehiscence of a jejunal suture in a patient submitted to aorto-enteric fistula repair: a 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.

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]

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.

[Mainly abdominal "complex" polytrauma. Considerations on surgical strategy and clinical case report]

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.

[Conservative treatment of the digestive fistulas: personal experience]

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.

[The congenital cystic dilatation of the liver and bile ducts (CDB): our experience]

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.

[Liver rupture in HELLP syndrome. Report of a case]

Liver rupture and hemorrhage, are the most unusual and serious complications of HELLP syndrome (hemolysis--elevated liver enzymes--low platelet count). The management should be aggressive by treating coagulopathy and favouring a prompt delivery. Liver rupture remains a surgical emergency with control of bleeding based on trauma surgery. The aggressive approach to the management of these patients led to a remarkable decrease of mortality rates.
