Torso computed tomography in blunt trauma patients with normal vital signs can be avoided using non-invasive tests and close clinical evaluation.

PURPOSE: To determine whether torso CT can be avoided in patients who experience high-energy blunt trauma but have normal vital signs. METHODS: High-energy blunt trauma patients with normal vital signs were retrieved retrospectively from our registry. We reviewed 1317 patients (1027 men and 290 women) and 761 (57.8%) fulfilled the inclusion criteria. All patients were initially evaluated at the emergency room (ER), with a set of tests, part of a specific protocol. Patients with at least one altered exam at initial examination or after six-hour observation received a torso CECT. Sensitivity, specificity, accuracy, positive (PPV) and negative predictive values (NPV), and likelihood ratio (LH) of the protocol were evaluated. RESULTS: Of 761 patients, 354 (46.5%) received torso CECT because of the positive ER test, with 330 being true positive and 24 being false positive. The remaining 407 patients were negative at ER tests and did not receive torso CECT, showing a significantly (P < 0.001) lower Injury Severity Score (ISS). The positive and negative LH of the protocol to detect torso injuries were respectively 16.5 and 0.01 (overall accuracy of 0.96). CONCLUSIONS: Torso CT can be avoided without adverse clinical outcomes in patients who experience high-energy blunt trauma, are hemodynamically stable, and have normal initial laboratory and imaging tests.

Surveillance for early stages of colon cancer: potentials for optimizing follow-up protocols.

BACKGROUND: Although several meta-analyses showed the positive effects of follow-up on the prognosis of colon cancer (CC), international guidelines are not in accordance on appropriate tests and their time frequency to optimize surveillance. Furthermore, stratified strategies based upon risk grading have not been implemented. This approach may be useful to rationalize resources. METHODS: From 2006, all patients operated for an early stage CC (I, IIA, IIB) according to the 7th edition of the AJCC-2010 classification entered in a prospective surveillance program in accordance to our local guidelines. Patients who underwent surgical resection after 2009 have been excluded to guarantee at least a 5-year follow-up. Classic histopathologic prognostic factors such as grade, T and N status, lymphatic and vascular invasion were assessed. Moreover, tumor budding and tumor-to-stroma proportion were evaluated. RESULTS: We had complete records of 196 patients. Distribution was as follows: 65 (33.2%) in stage I, 122 (62.2%) in stage IIA, and 9 (4.6%) in stage IIB. Eleven patients (5.6%) had a disease recurrence (local or distant). The median recurrence time was 20 months (range 6-48). Nine patients (82%) had recurrence with 24 months, and 91% were asymptomatic and detected by ultrasound or CT scan. According to the log-rank test, the risk factors with significant effect on the disease-free survival (DFS) were the number of lymph nodes <12 (p = 0.027) and the vascular invasion (p = 0.021), while for the overall (OS), only the vascular invasion was significant (p = 0.043). By the univariate and multivariate analyses, DSF was significantly lower in patients with less than 12 nodes removed, with vascular invasion, and with left of double cancer. OS was negatively affected only by vascular invasion despite the hazard ratios were similar to DSF. Stage IIB was associated with a threefold-increased risk of reduced OS and DSF. CONCLUSIONS: Stages I and IIA appear to behave similarly and should be considered as true early stages. The detection of fibrosis and budding do not seem to add valuable information for prognosis. In early CC stages, the surveillance program should be maximized within the first two years.

Multi-Center Randomized Controlled Trial on the Effect of Triclosan-Coated Sutures on Surgical Site Infection after Colorectal Surgery.

BACKGROUND: Surgical site infection (SSI) remains the most frequent complication after colorectal resection. The role of sutures coated with antimicrobial agents such as triclosan in reducing SSI is controversial. METHODS: This was a multi-center randomized controlled trial with patients and outcome assessors blinded to treatment. The study was performed in four university referral hospitals. Patient candidates for elective colorectal resection were assigned randomly to abdominal incision closure with polyglactin 910 triclosan-coated sutures (triclosan group) or with polyglactin 910 without triclosan (control group). The primary outcome was the rate of SSI within 30 d after hospital discharge. The secondary outcomes were the overall rate of incision complications and length of hospital stay (LOS). RESULTS: Two hundred eighty-one patients (triclosan group: 140; control group: 141) were analyzed after randomization. The rate of SSI was 12.9% (18/140) in the triclosan group versus 10.6% (15/141) in the control group (odds ratio: 1.24; 95% confidence interval: 0.60-2.57; p=0.564). Secondary outcome analysis showed an overall incision complication rate of 38.3% in the control group versus 45.7% in the triclosan group (odds ratio: 1.36; 95% confidence interval: 0.84-2.18; p=0.208). Median LOS was 11 d in both groups (p=0.55). CONCLUSIONS: Surgical sutures coated with triclosan do not appear to be effective in reducing the rate of SSI.

Intestinal obstruction by a pancreatic bezoar: a case report.

CONTEXT: Pancreatic pseudocysts are relatively common complications of pancreatitis. A pseudocyst can result from an episode of acute pancreatitis, exacerbation of chronic pancreatitis, or trauma. Treatment is indicated for persistent, symptomatic pseudocysts and in the case of related complications. CASE REPORT: We describe the case of a 66-year-old man who referred to our department for bowel obstruction caused by a necrotic pancreatic bezoar occurring 16 days after the patient underwent a jejunal-pseudocyst anastomosis performed to treat a post-pancreatitis voluminous pseudocyst obstructing the gastric outlet. CONCLUSION: In case of intestinal obstruction after a jejunal-pseudocyst anastomosis, pancreatic bezoar should be considered in the armamentarium of the differential diagnosis.

Enhanced recovery strategies in colorectal surgery: is the compliance with the whole program required to achieve the target?

PURPOSE: The complexity of "fast track" (FT) surgery might decrease its applicability in daily practice and extensive diffusion. The aim of this study was to understand if the positive effect of FT on the outcome might be affected by the number, type, level of evidence of the components, or their possible combinations. METHODS: We performed a Medline, Embase, Pubmed, and Cochrane Library literature search of randomized and non-randomized trials comparing FT to conventional care (CC) in elective colorectal operations. By a meta-analytic approach, the effect of FT was estimated by the risk ratio (RR) with a 95 % confidence interval (CI) for the risk of post-operative complications. RESULTS: The analysis included 53 studies (36 non-RCTs with and 17 RCTs), with 4,100 patients in the FT group and 4,424 patients in the CC group for a total of 8,524 patients. Fifty-six different item combinations were observed. The median rate of strategy implementation was 50 %. The positive effect of FT over CC was observed regardless the number (<10 vs. ≥10) of strategies used (RR = 0.80; 95 % CI 0.66-0.98 and RR = 0.75; 95 % CI 0.65-0.87, respectively), the application of items with strong vs. low level evidence (RR = 0.78; 95 % CI 0.67-0.90 and RR = 0.76; 95 % CI 0.63-0.92, respectively), or the frequency (≥80 vs. <80 %) of items implemented (RR = 0.80; 95 % CI 0.69-0.93 and RR = 0.73; 95 % CI 0.61-0.87, respectively). CONCLUSION: The positive effects of FT seem to be achieved regardless the multiplicity and variance of item grouping.

Acute cholecystitis: the golden 72-h period is not a strict limit to perform early cholecystectomy. Results from 316 consecutive patients.

PURPOSE: Early laparoscopic cholecystectomy (ELC) is the treatment of choice for acute cholecystitis (AC), but the optimal surgical timing is controversial. The aim of this study was to retrospectively verify the outcome of patients with AC according to different timing of cholecystectomy. METHODS: Patients undergoing cholecystectomy for AC from 2006 to 2012 were stratified into two groups: initial admission cholecystectomy (IAC) and delayed cholecystectomy (DC, after at least 4 weeks). Among IAC, a subgroup undergoing immediate cholecystectomy (IC, within 72 h of symptom onset) was further analyzed. RESULTS: Three-hundred and sixteen consecutive patients were studied. IAC group included 262 patients (82.9 %) and DC group included 54 patients (17.1 %). The two groups were similar in conversion rate, operation length, and overall complication rate. The total length of hospitalization was longer in DC patients (p = 0.005). Among DC patients, 25.9 % required re-hospitalization while waiting an elective procedure. In the group undergoing IC (66 patients), conversion rate, length of operation, and postoperative morbidity were similar to that of the IAC group. Length of stay was shorter in IC group (p < 0.001). Multivariate analysis identified moderate-severe AC grading and ASA score ≥ 3 as predictors of postoperative complications. CONCLUSIONS: The timing of cholecystectomy for AC does not seem to affect conversion rate and postoperative morbidity. Therefore the 72-h period should not be considered a strict limit to perform LC, provided that the operation is carried out during the initial hospital admission.

Is expertise in pediatric surgery necessary to perform laparoscopic splenectomy in children? An experience from a department of general surgery.

Splenectomy is frequently required in children for various hematologic pathologic findings. Because of progress in minimally invasive techniques, laparoscopic splenectomy (LS) has become feasible. The objective of this report is to present a monocentric experience and to evaluate the efficacy of and complications observed after laparoscopic splenic procedures in a department of general surgery. 57 consecutive LSs have been performed in a pediatric population between January 2000 and October 2010. There were 33 females and 24 males with a median age of 12 years (range 4-17). Indications were: hereditary spherocytosis 38 cases, idiopathic thrombocytopenic purpura 10, sickle cell disease (SCD) 6, thrombocytopenic thrombotic purpura 2 and non-hodgkin lymphoma 1 case. Patients were operated on using right semilateral position, employing Atlas Ligasure vessel sealing system in 49 cases (86%) and Harmonic Scalpel + EndoGIA in 8. In 24 patients (42.1%), a cholecystectomy was associated. Two patients required conversion to open splenectomy (3.5%). In three cases, a minilaparotomy was performed for spleen removal (5.2%). Accessory spleens were identified in three patients (5.2%). Complications (8.8%) included bleeding (two), abdominal collection (one) and pleural effusion (two). There was no mortality. Average operative time was 128 min (range 80-220). Average length of stay was 3 days (range 2-7). Mean blood loss was 80 ml (range 30-500) with a transfusion rate of 1.7% (one patient). Laparoscopic spleen surgery is safe, reliable and effective in the pediatric population with hematologic disorders and is associated with minimal morbidity, zero mortality, and a short length of stay. Ligasure vessel sealing system shortened operative time and blood loss. On the basis of the results, we consider laparoscopic approach the gold standard for the treatment of these patients even in a department of general surgery.

Bleeding from duodenal ulcer in a patient with bilio-pancreatic diversion.

Scopinaro's bilio-pancreatic diversion is considered as an acceptable malabsorptive surgical approach for the treatment of morbid obesity. We describe a case of acute recurrent gastro-intestinal bleeding in a patient with a previous Scopinaro's bilio-pancreatic diversion. At the first admission in our department, gastroscopy, colonoscopy, contrast-enhanced computerized tomography and angiography resulted negative for active bleeding. Hypovolemic shock indicated laparotomy and an intraoperative enteroscopy performed through a small enterotomy showed an ulcerative perforation sourced in an ischemic portion of a distended duodenal stump, with a bleeding branch of gastro-duodenal artery at the bottom. Hemorrhage was stopped with stitches. Two years later a new episode of duodenal bleeding associated with severe malnutrition occurred. A covered chronic ischemic perforation sustained by duodenal distension due to biliopancreatic limb sub-obstruction appeared to be the most probable etiology of the recurrent duodenal bleeding. The patient underwent again to laparotomy and adhesiolysis; hemorrhage was stopped by means of ligation of gastroduodenal artery and bilio-pancreatic diversion was converted into a standard Roux-en-Y gastroenterostomy with an entero-entero anastomosis 40 cm from the Treitz ligament in order to restore an anatomo-functional condition guaranteeing normal absorption and intestinal transit. After Scopinaro's bilio-pancreatic diversion duodenal bleeding can represent a rare serious presentation of biliopancreatic limb obstruction; because of the complex anatomical reconstruction performed during this intervention, the duodenum results unavailable during upper gastro-intestinal endoscopy, and if a duodenal bleeding is suspected laparotomy followed by enteroscopy represents an effective diagnostic approach.
