Long term results of video-assisted anal fistula treatment for complex anal fistula: another shattered dream?

AIM: Complex anal fistula represents a burden for patients, and its management is a challenge for surgeons. Video-assisted anal fistula treatment (VAAFT) is one sphincter-sparing technique. However, data on its long-term effectiveness are scant. We aimed to explore the outcomes of VAAFT in a retrospective cohort of patients referred to a tertiary centre. METHOD: Consecutive adult patients with a minimum of 2 years' follow-up after VAAFT were reviewed. Patients were followed up to 5 years postoperatively. Failure was defined as incomplete healing of the external orifice(s) during the first 6 months. Recurrence was defined as new radiologically and/or clinically confirmed onset of the fistula after primary healing. A generalized linear model was fitted to evaluate the association between failure and sociodemographic characteristics. Predictors of recurrence were determined in a subgroup analysis of patients found to be free from disease at 6 months postoperatively. RESULTS: Overall, 106 patients (70% male; mean age 41 years) were reviewed. Of these 86% had a previous seton placement. Fistulas were either high trans-sphincteric (74%), suprasphincteric (12%) or extrasphincteric (13%). Eight (7%) patients experienced postoperative complications, none of which required reintervention. Mean follow-up was 53 ± 13.2 months. VAAFT failed in 14 (13%) patients. The overall recurrence rate ranged from 29% at 1 year to 63% at 5 years. Multiple external orifices, suprasphincteric fistula, younger age, previous surgery and higher complexity of the fistulous tract were independent risk factors for recurrence. CONCLUSION: VAAFT is a safe sphincter-sparing technique. The initially high success rate decreases over time and relates to a higher degree of complexity.

A pilot study on staged surgery by delta video-assisted anal fistula treatment (dVAAFT) for complex anal fistula.

Complex anal fistulas (CAF) present a challenge in achieving healing while preserving anal sphincter function. This study aims to introduce a novel staged approach for CAF treatment, combining video-assisted anal fistula treatment (VAAFT), seton placement, and other staged approaches. Consecutive patients with CAF underwent the staged approach involving VAAFT and seton placement. Data on patient demographics, fistula characteristics, and operative findings were collected. Pre-operative work-up included clinical evaluation, endoanal ultrasonography (EAUS), and magnetic resonance imaging (MRI). Surgical techniques and outcomes were evaluated. Eighteen patients (median age 38 years) were included. Misplacement of a previously placed seton was observed in 64% of cases. VAAFT combined with seton placement achieved simplification and healing of secondary tracts in 66% of cases. Operative times significantly decreased across interventions. At a median follow-up of 14 months, complete healing was achieved in 2 patients, with 1 patient demonstrating persistence of the fistula. Post-operative complications were observed in 11% of patients, with no deterioration in continence. The staged approach combining VAAFT, seton placement, and staged procedures offers a potential solution for treating CAF. VAAFT provides diagnostic and therapeutic benefits, simplifying the fistula anatomy and optimizing seton placement. The approach allows subsequent procedures based on individual fistula characteristics.

Complete Lymphadenectomy for Clinical Stage I Lepidic Adenocarcinoma of the Lung: Is it justified?

The role of a systematic lymphadenectomy in patients undergoing surgery for clinical stage I lung lepidic adenocarcinoma is still unclear. In the last years, some authors have advocated the possibility to avoid a complete lymph-node dissection in this setting. Results of patients who received systematic hilar-mediastinal nodal dissection for this oncologic condition are here reported. Between 2012 and March 2019, 135 consecutive patients underwent lung resection for clinical stage I lepidic adenocarcinoma, at our institution. Only patients (n = 98) undergoing lobectomy or sublobar resection associated with systematic hilar-mediastinal nodal dissection were retrospectively enrolled in the study. Patients' mean age was 67.8 ± 8.7 years (range 37-84). Three were 52 females and 46 males. Resection was lobectomy in 77.6% (n = 76) and sublobar in 22.4% (n = 22). All the resections were complete (R0). Histology was lepidic predominant adenocarcinoma in 85 cases and minimally invasive adenocarcinoma in 13 cases. At pathologic examination, N0 was confirmed in 78 patients (79.6%), while N+ was found in 20 cases (20.4%), (N1 in 12, 12.2% and N2 in 8, 8.2%). No mortality occurred. Complication rate was 8.2%. At a median follow-up of 45.5 months, recurrence rate was 26.5%. Disease-free 5-year survival was 98.6% for stage I, 75% for stage II and 45% for stage III, p < 0.001. A complete nodal dissection can reveal occult nodal metastases in lepidic adenocarcinoma patients and can increase the accuracy of pathologic staging. N1/N2 disease is a negative prognostic factor for this histology. A systematic lymph-node dissection should be considered even in this setting.

Trans-anal minimally invasive surgery (TAMIS) versus trans-anal endoscopic microsurgery (TEM): a comparative case-control matched-pairs analysis.

AIM: Since its introduction, transanal endoscopic microsurgery (TEM) has become the treatment of choice for rectal benign lesions not amenable to flexible endoscopic excision and for early rectal cancer. Disposable soft devices as the Trans-anal Minimally Invasive Surgery (TAMIS) are a valid alternative to non-disposable rigid trans-anal endoscopic microsurgery (TEM) platforms. The aim of the present study is to compare TEM and TAMIS in terms of incidence of R1 resection and lesion fragmentation which were combined in a composite outcome called quality resection. Perioperative complication and operative time were also investigated. METHODS: A total of 132 patients were eligible for this study of whom 63 (47.7%) underwent TAMIS and 69 (52.3%) underwent TEM. Patients were extracted for from a prospective maintained database and groups resulted homogenous after matching using propensity score in terms of size of the lesion, height from the anal verge, position within the rectal lumen, preoperative histology, neoadjuvant treatment. A multivariate logistic and linear regression analysis was carried out using those variables that have significant independent relationship with the quality of surgical resection and operative time. RESULTS: The incidence of R0 resection and lesion fragmentation was similar between groups. No differences were found in terms of perioperative complication. TAMIS was associated with less setup time and less operative time compared with TEM. Variables influencing quality resection at the multivariate analysis were larger lesion (> 5 cm) and ≥ T2 stage. Variables influencing operative time were surgical procedure (TEM vs TAMIS), height from the anal verge and size of the lesion. CONCLUSION: The present study shows that TEM and TAMIS are equally effective in terms of quality of local excision and perioperative complication. TAMIS resulted less operative time consuming compared to TEM.

Secondary aortoenteric fistula successfully treated with staged endovascular repair and duodenal resection without graft removal.

Secondary aorto-enteric fistulae (SAEF) are rare life-threatening complications that occur after abdominal aortic graft implant to treat aortic aneurysm or occlusive disease. Conventional treatments such as extra-anatomic bypass grafting with aortic ligation and subsequent graft removal with bowel repair are associated with a 25% to 90% operative mortality rate. In the emergency setting, patients unsuitable for major arterial surgery may benefit from a staged, less invasive approach. We present a case of SAEF treated with endoluminal deployment of a stent graft followed by duodenojejunal resection and anastomosis without further aortic reconstruction and graft removal.

Superior Vena Cava Replacement for Thymic Malignancies.

BACKGROUND: Advanced-stage thymic tumors infiltrating the superior vena cava (SVC), when radically resectable, can be surgically treated by SVC prosthetic replacement within a multimodality therapeutic approach. We hereby present our series of patients undergoing SVC resection and prosthetic reconstruction for stage III or IV thymic malignancies. METHODS: Between 1989 and 2015, 27 patients with thymic tumors (21 thymoma, 6 thymic carcinoma) infiltrating the SVC underwent radical resection with a SVC prosthetic replacement by a bovine pericardial conduit in 12 cases, a polytetrafluoroethylene conduit in 13, a porcine pericardial conduit in 1, and a saphenous vein conduit in 1. All the patients underwent vascular conduit reconstruction by the cross-clamping technique. RESULTS: Six patients were myasthenic. All resections were complete (R0). Twelve patients received induction treatment. Pulmonary resection was associated in 16 patients (11 wedge, 5 pneumonectomy). Twenty-two patients were Masaoka stage III and 5 were stage IVa. Mortality rate was 7.4%; no mortality was related to the vascular reconstruction. Major complication rate was 11.1%. At a median follow-up of 58 (range, 4 to 134) months, recurrence occurred in 9 (36%) patients. Three- and 5-year overall survival rates were 80% and 58.1%, respectively. Three-and 5-year cancer-specific survival were 90.5% and 75.4%. Cancer-specific survival rates of thymoma patients at 5 years were 93.8%. Five-year cancer-specific survival of all stage III patients was 77.1%. Thymic carcinoma histology was a negative prognostic factor. Long-term patency of the pericardial conduits was 100%. CONCLUSIONS: En bloc resection and conduit reconstruction of the SVC is a good option to allow radical resection of locally advanced thymic tumors. A heterologous pericardial conduit represents the favorite option in our experience.

Do Repeated Operations for Recurrent Colorectal Lung Metastases Result in Improved Survival?

BACKGROUND: Lung metastases occur in 10% to 20% of patients with colorectal cancer (CRC). Lung metastatic pathways of CRC are poorly known, and the optimal management for recurrent lung metastases remains uncertain. METHODS: Long-term oncologic outcomes of 203 patients with CRC lung metastases who underwent metastasectomy were investigated in this multicenter retrospective study. Ninety-two patients (45.3%) with tumor relapse underwent repeated metastasectomy and 11 (5.4%) received a third metastasectomy for a second relapse. Demographic and clinical data, including histologic grade of primary tumor, presence of CRC liver metastases, type of primary tumor resection, number, size, location, and resection type of pulmonary metastases, were evaluated. Overall survival (OS) and disease-free survival were analyzed. Cox regression model was performed to identify variables that influenced OS. RESULTS: One hundred seventy-three patients (85.2%) received a wedge resection, 21 (10.3%) underwent pulmonary lobectomy, and 9 (4.4%) underwent other procedures (pneumonectomy, bilobectomy). The mean follow-up was 39 months (range: 7 to 154 months). One-, 3-, and 5-year global OS from CRC diagnosis was 99%, 80%, and 60%, respectively, and 97%, 60%, and 34% from the first metastasectomy, respectively. Log-rank test between OS (one versus repeated metastasectomy) did not show significant differences (p = 0.659). Cox regression model showed that nodal status (hazard ratio [HR] 17.7, p = 0.008) and administration of adjuvant chemotherapy (HR 0.33, p = 0.026) are risk and protective factors, respectively, for OS. CONCLUSIONS: Repeated pulmonary metastasectomy should be offered to patients with metastatic CRC because there are no differences in terms of OS between patients undergoing single and repeated metastasectomy. Adjuvant chemotherapy should be suggested in case of metastatic CRC.

Tumor-Stroma Ratio is an independent predictor for overall survival and disease free survival in gastric cancer patients.

BACKGROUND: Despite different prognostic factors have been already studied, patients undergoing potentially curative resection for gastric cancer, still have a poor outcome. There is therefore the need to identify novel prognostic factors. Recently, Tumor-Stroma Ratio (TSR) was proven to be associated with prognosis in different types of cancers. Aim of this study was to evaluate the prognostic value of TSR in gastric cancer patients. METHODS: 106 patients underwent gastrectomy between January 2004 and December 2015. Demographics and histopathological characteristics were collected. We considered a 50% TSR cutoff value to divide patients in Stroma-Rich (≥50%) and Stroma-Poor (<50%) groups. RESULTS: Forty-one (38.7%) patients were classified as Stroma-Poor while 65 (61.3%) as Stroma-Rich (61.3%). The Stroma-Rich patients had a higher number of positive lymph-nodes, lymph node ratio (LNR), a higher percentage of T3/T4 local invasion and N2/N3, and a more advanced TNM. Moreover, these patients showed a higher percentage of lymphovascular and perineural invasion. With a median FU of 38 months Stroma-Rich patients had a significantly worse 5-years actuarial overall survival (OS) and disease free survival (DFS) compared to Stroma-Poor patients. Moreover, the multivariate analysis showed that Stroma-Rich was the only independent factor associated with OS and DFS together with TNM-Stage. CONCLUSIONS: TSR is an independent marker of poor prognosis in patients with gastric cancer that should be readily incorporated into routine clinical pathology reporting. Identification of sensitive markers for patients who had undergone curative gastrectomy and who are at high risk of recurrence could provide useful information for planning follow-up after surgery or intensive and or/targeting adjuvant chemotherapy.

Influence of perineural invasion in predicting overall survival and disease-free survival in patients With locally advanced gastric cancer.

BACKGROUND: The aim of the present study was to evaluate the prognostic significance of perineural invasion (PNI) in locally advanced gastric cancer patients who underwent D2 gastrectomy and adjuvant chemotherapy. METHODS: The records of a series of 103 patients undergoing D2 gastrectomy with curative intent combined with adjuvant chemotherapy from January 2004 to December 2014 were retrospectively reviewed. RESULTS: PNI was positive in 47 (45.6%) specimens. The 1-, 3-, and 5-year overall survival rates were 81%, 55%, and 42%, respectively. The 1-, 3-, and 5-year disease-free survival (DFS) rates were 76%, 57%, and 49%, respectively. A multivariate analysis showed that age number of positive lymph nodes, T stage, and PNI were independently associated with overall survival. Regarding DFS, the multivariate analysis showed that only PNI was independently associated with DFS. CONCLUSIONS: PNI and T stage and positive lymph nodes are independent markers of poor prognosis in patients with gastric cancer. PNI should be incorporated in the postoperative staging system for planning follow-up after surgery and in our opinion to propose more aggressive postoperative therapies in PNI-positive patients.

Technologies, technical steps, and early postoperative results of transanal TME.

INTRODUCTION: First described in 1982, TME overcomes most of the concerns regarding adequate local control after anterior rectal resection. TME requires close sharp dissection along the so-called Heald's plane down to the levators, with distal dissection often cumbersome. In recent years, Transanal TME was introduced with the aim to improve distal rectal dissection and quality of mesorectal excision. MATERIAL AND METHODS: A prospective, non-randomized study, started in 2013, is currently ongoing in two Italian Centers. Study objectives were assessing the safety of TaTME and TME quality. TaTME technique and technologies as performed in these centers and cumulative results at ≤30 postoperative days of the first 102 patients are reported. RESULTS: Early postoperative morbidity and mortality rates were 33.3% (34 pts, 16 Clavien-Dindo I + II and 18 Clavien-Dindo III + IV + V), and 1.96% (two deaths), respectively. The quality of mesorectal excision according to Quirke was: complete in 97.1% and nearly complete in 2.9% of the cases. CONCLUSIONS: The results confirm the effectiveness of TaTME, especially regarding the quality of the mesorectal dissection. Open questions regarding standardization, anatomical landmarks, indications, morbidity (with special regard to local infection and sepsis), learning curve and oncological outcomes require further answers from larger studies and RCTs before definitive validation of this procedure. .

Single-incision laparoscopic cholecystectomy: does it work? A systematic review.

BACKGROUND: Single-incision laparoscopic cholecystectomy (SILC) has been widely introduced into the clinical practice, but the real clinical benefits for patients still remain a matter of debate. We conducted a systematic review, according to the PRISMA guidelines comparing clinical and peri-operative outcomes of SILC and conventional laparoscopic cholecystectomy (CLC). METHOD: A literature search, including only randomised controlled trials (RCTs), was performed via PubMed, Google Scholar, Cochrane Library and Embase database. The reviewers extracted data from the manuscripts of selected articles including patient demographics, operative time, morbidity rate, post-operative length of stay, conversion rate, cost data, pain and satisfaction with cosmetic results. RESULT: Seventeen RCTs matching the inclusion criteria were finally selected for the analysis. A total of 1293 patients were involved in the review, including 663 (51.3 %) patients who have undergone SILC and 630 (48.7 %) patients who have undergone CLC. Post-operative pain was significantly worse in SILC patients in four studies, in CLC patients in four studies, while in the remnants seven studies, no differences in pain scores were found. Data on satisfaction for post-operative cosmetics were significantly better for SILC patients in all studies but two. Operating time was significantly longer in SILC group while there is no statistically significant difference in conversion rate. Morbidity rate was similar in both groups, as was the incidence of bile duct injuries. Costs were significantly higher in SILC group. SILC was considered a more challenging procedure in all studies. CONCLUSION: The role of SILC is still controversial. Until now, no real significant benefit has been proven: overall satisfaction is the only clear advantage of SILC, and this is mainly related to cosmetic results. Indications to SILC are mainly limited to patients with uncomplicated disease, with BMI ≤ 30 kg/m(2), whose surgery is unlikely to be converted to an open or multiport approach.

Treatment of esophagojejunal anastomosis leakage: a systematic review from the last two decades.

Esophagojejunal anastomosis leakage is one of the major complications after total gastrectomy for gastric cancer and is an independent predictor of survival. Our aim is to systematically review the literature and discuss the reported therapeutic approaches to identify the best therapeutic approach. Pubmed, EMbase, Cochrane Library, CILEA Archive, BMJ Clinical Evidence, and Up ToDate databases were screened limiting the research to articles written in English from January 1992 through December 2013. This way a total of 474 manuscripts were retrieved for furthermore evaluation. Eleven manuscripts were considered eligible and the study is focused on those works. We analyzed a total of 3,893 patients and 114 cases of esophagojejunal anastomosis leakage. Different treatments were grouped into three main categories: conservative approach (66 cases), endoscopic approach (21 cases), and surgical approach (27 cases). The overall mortality rate is 26.32 per cent and surgical approach showed the higher rate. According to the reported data, a complete resolution of the leakage can be achieved in an interval ranging from 7 to 28 days in the group treated conservatively. Conservative approach should always be considered as the treatment of choice. Reoperation may be necessary in case of wide dehiscence or when other treatments fail; therefore, the high mortality rate related to this procedure is due to the comorbidities of patients undergoing relaparotomy. Finally, endoscopic approach with endoclips seems promising but needs furthermore studies.

Value of preoperative inflammation-based prognostic scores in predicting overall survival and disease-free survival in patients with gastric cancer.

BACKGROUND: This study was designed to identify which are the best preoperative inflammation-based prognostic scores in terms of overall survival (OS) and disease-free survival (DFS) in patients with gastric cancer. METHODS: Between January 2004 and January 2013, 102 consecutive patients underwent resection for gastric cancer at S. Andrea Hospital, "La Sapienza", University of Rome. Their records were retrospectively reviewed. RESULTS: After a median follow up of 40.8 months (8-107 months), patients' 1-, 3-, and 5-year OS rates were 88, 72, and 59 %, respectively. After R0 resection, the 1-, 3-, and 5-year DFS rates were 93, 74, and 56 %, respectively. A multivariate analysis of the significant variables showed that only the modified Glasgow prognostic scores (p < 0.001) and PI (p < 0.001) were independently associated with OS. Regarding DFS, multivariate analysis of the significant variables showed that the modified Glasgow prognostic score (p = 0.002) and prognostic index (p < 0.001) were independently associated with DFS. CONCLUSIONS: The results of this study show that modified Glasgow prognostic score and prognostic index are independent predictors of OS and DFS in patients with gastric cancer.

Is a preoperative assessment of the early recurrence of pancreatic cancer possible after complete surgical resection?

BACKGROUND/AIMS: The prognosis of pancreatic adenocarcinoma (PAC) is poor. The serum carbohydrate antigen 19-9 (CA 19-9) level has been identified as a prognostic indicator of recurrence and reduced overall survival. The aim of this study was to identify preoperative prognostic factors and to create a prognostic model able to assess the early recurrence risk for patients with resectable PAC. METHODS: A series of 177 patients with PAC treated surgically at the St. Andrea Hospital of Rome between January 2003 and December 2011 were reviewed retrospectively. Univariate and multivariate analyses were utilized to identify preoperative prognostic indicators. RESULTS: A preoperative CA 19-9 level >228 U/mL, tumor size >3.1 cm, and the presence of pathological preoperative lymph nodes statistically correlated with early recurrence. Together, these three factors predicted the possibility of an early recurrence with 90.4% accuracy. The combination of these three preoperative conditions was identified as an independent parameter for early recurrence based on multivariate analysis (p=0.0314; hazard ratio, 3.9811; 95% confidence interval, 1.1745 to 15.3245). CONCLUSIONS: PAC patient candidates for surgical resection should undergo an assessment of early recurrence risk to avoid unnecessary and ineffective resection and to identify patients for whom palliative or alternative treatment may be the treatment of choice.

The usefulness of a Trauma Registry and the role of the general surgeon in the multidisciplinary approach to trauma patients: 3-year experience at Sant'Andrea University Hospital in Rome.

The purpose of this study is to verify the usefulness of a multidisciplinary Trauma Registry in the evaluation of trauma, particularly in relation to the number of specialists involved, and to analyze the effective role of the general trauma surgeon in an integrated trauma care system. The present study was performed by analyzing data from the Trauma Registry of the University Hospital Sant'Andrea in Rome, which was set up in March 2006. Data recorded between March 2006 and March 2009 was considered for the present study. The severity of trauma was categorized by dividing patients into 4 subgroups based on the value of ISS: minor injuries (ISS 1-8), moderate (ISS 9-15), severe (ISS 16-24) and very severe (ISS> 24). Patients who had an ISS greater than 9 were taken into account for further analysis and comparison. To evaluate the significance of the multidisciplinarity the patients were stratified in subgroups considering the number of specialists involved in relation to the anatomic location of injuries. In the 1386 trauma patients entered in the registry, the mean and median ISS value were 10.7 ± 8.4 and 9 respectively. The overall mortality and morbidity were 4.1% and 7.4% respectively. There was a statistically significant linear relationship between the number of specialists involved and the ISS (multidisciplinarity / ISS r = 0.493, p <0.001). Patients with ISS greater than 9 were 358, 25.8% of all cases. The mean ISS was 21.4 ± 10.3. Mortality and morbidity rates were 9.8% (35 patients) and 22.1% (79 patients) respectively. The average number of specialists involved was 2.4 ± 1.1, median 2 (range 1- 6). Results confirmed the significance of the multidisciplinary treatment for patients with trauma and the central role played by the general surgeon.

Emergency presentation of intestinal lymphoma.

PURPOSE: The aim of the present study was to evaluate the clinical features, management and outcome of patients submitted to emergency surgery because of intestinal lymphoma. METHODS: A consecutive series of fourteen patients with gastrointestinal tract lymphoma referred for emergency surgery between March 2006 and May 2010 was retrospectively analyzed. RESULTS: Patients including 9 males (64.2%) and 5 females (35.7%). The mean age of male and female was 55.4 + 21.2 and 78.4 + 9.0 respectively. The difference was statistically significant (p <0.04). Ileum was the most common location (13 cases, 86.6%) and a small bowel resection was the commonest surgical procedure performed. Presence of etiological risk factor for developing intestinal lymphoma was detected in 6 patients (40%). The overall morbidity rate was 40.0% (6 patients) and the mortality rate was 53,3% (8 patients). The estimated 12, 24, and 36-months overall survival rate was 56%, 33%, and 22% respectively. DISCUSSION: Our study reports an elevated overall mortality accounting for 8 patients which were all but two of advanced stage; 6 patients died in the postoperative course. Univariate and multivariate analysis failed to show significant differences maybe because the total number of subjects was too small to reach statistical significance. However the Odds Ratio was significantly high for the presence of etiological risk factor (OR 7.50) and perforation as presenting symptom (OR 6.67). CONCLUSION: An aggressive surgical attitude comprising an ample ileum resection is needed in almost all cases because an acute presentation is closely related with an advanced stage of the disease and with a high risk for anastomotic disruption, both conditions leading to a poor short and long-term survival.

The prognostic significance of thoracic and abdominal trauma in severe trauma patients (Injury severity score > 15).

The aim of the present study was to assess the prognostic significance of thoracic and abdominal trauma in severely injured patients. A retrospective analysis was performed based on data from the period from March 1 2006 to December 31 2007, taken from the Trauma Registry of the University Hospital "SantAndrea" in Rome. A total of 844 trauma patients were entered in a database created for this purpose, and only patients with an Injury Severity Score (ISS) > 15, (163 patients, 19.3%), were selected for the present study. These patients were divided into 2 groups: Group A (103 patients, 63.2%), consisting of patients with at least one thoracic injury, and Group B (46 patients, 28.2%) consisting of patients with concomitant thoracic and abdominal injuries. The impact of thoracic and abdominal trauma was studied by analyzing mortality and morbidity, in relation to patient age, cause and dynamics of trauma, length of hospital stay, and both ISS and New ISS (NISS). In a vast majority of cases, the cause of trauma was a road accident (126 patients, 77.3%). The mean age of patients with ISS > 15 was 45.2 +/- 19.3 years. The mean ISS and NISS were 25.7 +/- 10.5 and of 31.4 +/- 13.1 respectively. The overall morbidity and mortality rates were 18.4% (30 patients) and 28.8% (47 patients) respectively. In Group A the mortality rate was 23.3% (24 patients) and the morbidity rate was 33.9% (35 patients). In Group B mortality and morbidity rates were 369% (17 patients) and 43.5% (20 patients) respectively. It was shown that the presence of both thoracic and abdominal injuries significantly increases the risk of mortality and morbidity. In patients with predominantly thoracic injuries, NISS proved to be the more reliable score, while ISS appeared to be more accurate in evaluating patients with injuries affecting more than one region of the body.

The epidemiology and clinical evaluation of abdominal trauma. An analysis of a multidisciplinary trauma registry.

Abdominal trauma is present in 7-10% of all trauma victims, and in cases of severe trauma is often found together with orthopedic, thoracic or central nervous system (CNS) injuries. The aim of the present study was to perform a comparative analysis of abdominal trauma and trauma involving other body regions, evaluating the prognostic significance of abdominal injuries in patients with severe trauma, based on data from a multidisciplinary trauma registry. Data from the period from March 1 2006 to December 31 2007 was collected from the trauma registry of the University Hospital Sant'Andrea in Rome, Italy. There were 25.875 patients (31.4%) with the diagnosis of trauma out of a total of 82.293 patients admitted to the emergency department. Eight hundred forty-four patients were selected according to specific inclusion criteria and patients with abdominal injuries were further selected. The following data were investigated: patient age, the trauma mechanism, duration of recovery, Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), type and the incidence of abdominal and extra-abdominal injuries. Morbidity and mortality, especially in patients with spleen and liver injuries, were analyzed. There were 79 patients (9.3%) with abdominal trauma. Their mean ISS was 25.7 +/- 14.3. Sixty-one (77.2%) of these patients had sustained severe trauma (ISS > 15). Forty-one patients (51.8%) underwent surgery. The overall mortality rate was 24.1%, 19 patients all with ISS > 15, so that the mortality rate for patients with severe trauma was 31.2%. Splenic trauma was the most frequent, and was found in 36 patients (45.6%) whose mean ISS was 31.1 +/- 144. Twenty-two patients (61.6%) were treated surgically; a total of 21 splenectomies and one laparoscopic procedure to control bleeding were performed. Overall mortality among patients with splenic trauma was 30.5% (11 patients), with an average spleen AIS of 3.3 +/- 0.8 (died vs. survived p = n.s.). Liver injuries were found in 33 patients (41.7%). The mean ISS was 28.4 +/- 11.6. Sixty-five percent of the patients were given nonsurgical treatment. Overall mortality among liver trauma patients was 24.2% (8 patients) with an average liver AIS of 3.2 +/- 0.3 (died vs. survived p < 0.05). In multivariate analysis, among the general population of trauma patients, the ISS (p < 0.001), patient age (p < 0.003), and an orthopedic (p < 0.002) or CNS injury (p < 0.006) proved to be significant independent predictors of the presence of an abdominal injury. Multivariate analysis showed that in patients with abdominal trauma, only the ISS (p < 0.001) was a significant independent predictor of mortality.

[Emergency colonic surgery: analysis of risk factors predicting morbidity and mortality]. / Chirurgia del colon in urgenza: analisi dei fattori di rischio di morbilità e mortalità.

The aim of the present study was to identify risk factors for morbidity and mortality in patients submitted to emergency colonic surgery. Between 1997 and 2008 157 patients, 106 of whom affected by colon cancer (67.5%) and 51 by benign disease (32.5%), were treated. The risk factors for morbidity and mortality were evaluated by univariate and multivariate analysis considering clinical and demographic data. The overall 30-day morbidity and mortality rates were 19.1% (30 patients) and 12.7% (20 patients), respectively. Among patients affected by cancer the mortality rate was 15% (16 patients) and the morbidity rate 23.6% (25 patients), while among the patients with benign disease the mortality rate was 7.8% (4 patients) and the morbidity rate 9.8% (5 patients). No postoperative surgical complications were noted. The strongest risk factors for early death were postoperative medical complications such as cardiopulmonary, renal, thrombo-embolic and infectious complications. The results of the univariate analysis showed that advanced age, neoplastic disease, advanced stage of cancer and associated medical disease prior to surgery play a role as risk factors for morbidity and mortality. In the multivariate analysis only the presence of associated medical disease proved to be a significant independent predictor of outcome. Emergency surgery for both neoplastic and benign colonic disease is still associated with an increased risk of death. Although restorative colectomy should be regarded as the first choice procedure in the emergency setting, Hartmann's procedure is still widely used in high-risk patients.
