RESUMEN
Even if cancer specific biomarkers are present in peripheral blood of cancer patients, it is very difficult to detect them with conventional technology because of their low concentration. A potential cancer biomarker is the HMGA1b protein, whose overexpression is a feature of several human malignant neoplasias. By taking advantage of the surface plasmon resonance (SPR) phenomenon, we realized a specific nano/technology-based assay for cancer detection. More in details, anti-HMGA1b monoclonal antibodies, whose affinity was previously defined by ELISA, were immobilized onto metallic surfaces to develop a direct SPR-based assay. After having analyzed blood samples from colorectal cancer patients and healthy people for the presence of HMGA1b, we observed a 2-fold increase of the HMGA1b levels in the blood of cancer patients with respect to the healthy control people. We conclude that the set-up technology might allow to detect a tumoral mass through the evaluation of HMGA1b protein blood levels.

BACKGROUND: Local recurrences of rectal cancer are best treated with surgical resection. Health-related quality of life is an important outcome measure in rectal cancer, but it has been poorly investigated in local recurrences. OBJECTIVE: The purpose of this study was to assess quality of life in patients receiving or not receiving surgery for locally recurrent rectal cancer. DESIGN: This was a prospective cohort study. SETTINGS: The study was conducted at a single tertiary care institution. PATIENTS: Patients presenting with local recurrent rectal cancer between December 2002 and December 2011 were included. A control group of patients with nonrecurrent rectal cancer was prospectively enrolled (planned ratio, 1:2). MAIN OUTCOME MEASURES: All of the patients received the core Quality of Life Questionnaire C30 of the European Organisation for Research and Treatment of Cancer preoperatively or at diagnosis and then 1 and 3 years later. We compared results according to oncologic clearance (R0 vs R1 vs R2 vs no surgery). Confounding variables were tested with a multivariate logistic regression. RESULTS: Forty-five patients (27 men), median age 62 years (range, 34-80 years), with recurrence were observed. Twelve (26.7%) were not fit for surgery. Twenty one (63.6%), 7 (21.2%), and 5 (15.2%) received R0, R1, and R2 resections. Data for 30 (90.9%) and 25 operated patients (75.75%) were available at 1- and 3-year follow-ups. Irrespective of type of surgery and multimodal treatments, patients receiving R0/R1 resections had improvement in quality of life in all of the domains compared with the R2 and no-surgery groups. Outcomes were inferior compared with nonrecurrent control subjects (N = 71). At 3 years, R0 patients reported scores equal to those of control subjects, with superior emotional functioning. R1 patients had worse symptoms and quality of life at 3-year follow-up. Surgery impaired survival and quality of life of R2 patients compared with those who were not operated on. LIMITATIONS: The study was limited because it involved a single center with a single senior surgeon. CONCLUSIONS: Quality of life of patients with locally recurrent rectal cancer is improved by R0 and ameliorated with R1 resection, irrespective of surgical extent. Full recovery, similar to that of nonrecurrent cancer survivors, can be expected in R0 patients but requires longer follow-up times. Surgery with macroscopic involvement of resection margins accelerates quality of life decline and shortens survival.

PURPOSE: Excisional hemorrhoidectomy (EH) can be complicated by high early (EP) and prolonged pain (PP). This study aimed to determine predictors of high postoperative pain and to develop a risk score suitable to identify patient candidates to a more active analgesic treatment. METHODS: We collected data of patients undergoing EH between January 2005 and September 2012 (development group). Patient-, disease-, surgery-, and surgeon-related characteristics were gathered. Anxiety was evaluated by means of STAI-Y. EP was assessed at 1-day, while PP at 15-day follow-up by means of a 10-cm VAS (cutoff, EP ≥ 5; PP ≥ 3 cm). On the basis of the odds ratio from a logistic regression, independent risk factors were assigned a weighted integer. The sum comprised the risk score, which was validated on a prospective cohort of patients undergoing EH between September 2012 and January 2014. RESULTS: Five hundred fourteen patients were included in development group. Incidence of EP was 18.3 %, with 40.4 % developing PP. Younger age, male gender, advanced education, constipation, external component, anxious state and trait, and high anal resting tone were independent predictors of EP. Previous pain exerted a protective effect. Incomplete postoperative evacuation, advanced education level, high anal resting tone, and anxious trait were predictors of PP. In the development group, the risk of EP ranged between 1 % (low risk) and 21 % (high risk). Receiver operating curve (ROC) analysis of validation group (n = 130) confirmed the discriminatory power of this model (area under the ROC = 0.69). CONCLUSION: The score can stratify the risk of EP following EH, identifying high-risk patient candidates to active analgesic administration or alternative surgical procedures.

INTRODUCTION: Surgical site infections (SSIs) affect costs of care and prolong length of stay. Crohn's disease (CD) represents an independent risk factor for SSI. The risk can be further increased by concomitant administration of immunosuppressive drugs and poor performance status at the time of surgery. Patients suffering from CD often need more than one surgical intervention during life, sometimes requiring fashioning of a stoma. The aim of this pilot study was to compare a portable device for negative pressure wound therapy (PICO, Smith & Nephew, London, UK) to conventional gauze dressings in patients undergoing surgery for stricturing CD. METHODS: Between January 2010 and November 2011, this controlled trial enrolled 30 patients, who were assigned to treatment with either PICO (n = 13) or conventional dressings (n = 17). Each patient completed a 3-month follow-up. RESULTS: Patients receiving PICO experienced significantly less postoperative wound complications (P = .001) and SSI (P = .017) compared with those who received conventional dressings. This resulted in shorter hospital stay (P = .0007). No significant differences in cosmetic results were found. CONCLUSION: These data suggest that PICO allows faster and safe discharge by reducing the incidence of SSI and wound-related complications in selected patients undergoing surgical intervention for stricturing CD. This could be particularly useful in patients receiving steroids.

Surgical site complications (SSC) negatively affect costs of care and prolong length of stay. Crohn's disease (CD) is a risk factor for SSC. CD patients often need surgery, sometimes requiring stoma. Our primary aim was to compare the effects on SSC of a portable device for NPWT (PICO, Smith & Nephew, London, UK) with gauze dressings after elective surgery for CD. Secondary aims were manageability and safety of PICO and its feasibility as home therapy. Between 2010 and 2012, 50 patients were assigned to treatment with either PICO (n = 25) or conventional dressings (n = 25). Each patient completed 12-month follow-up. Parameters of interests for primary aim were SSC, surgical complications, and readmission rates. Data on difficulties in managing PICO and device-related complications were also collected. Patients receiving PICO had less SSC, resulting in shorter hospital stay. At last follow-up, readmission rates were lower with PICO. No differences were observed in surgical complications between groups. No patients reported difficulties in managing the device. Among patients discharged with PICO, none needed to come back to the hospital for device malfunctioning or inability to manage it. PICO reduces SSC and length of stay in selected CD patients compared with conventional dressings. The device is safe and user friendly.

BACKGROUND: Gallbladder adenomyomatosis (GBA) is a hyperplastic disease affecting the wall of the gallbladder, with some typical features. It has historically been considered a benign condition, nevertheless recent reports highlighted a potential role of GBA in predisposing to malignancies of the gallbladder. DATA SOURCES: We reviewed the literature concerning GBA from its identification until July 2012. Owing to the relative rarity of the disease, studies often are case reports or case series. Thus we herein report a summary of the key-points concerning diagnosis and treatment of GBA, easily applicable in everyday practice, rather than a systematic review. Also, results are integrated with our recent experience. RESULTS: In our experience, we observed a trend toward an increase of GBA during the last years, probably due to enhanced ultrasonographic technical advancements and physician's expertise. GBA has distinctive imaging features. Several recent reports highlight the potential risk of cancer associated with GBA; however the disease is still classified as a benign condition. Although its correlation with malignancy has not been demonstrated, it is prudent to recommend cholecystectomy in some cases. However, in selected asymptomatic patients, a wait-and-see policy is a viable alternative. We propose an algorithm, based on GBA pathological pattern (diffuse, segmental, localized or fundal), suitable for decision-making. CONCLUSIONS: In symptomatic patients and if the diagnosis is doubtful, cholecystectomy is mandatory. Postponing surgery is an option to be offered to asymptomatic patients with low-risk GBA pattern who adhere to scheduled follow-ups.

BACKGROUND: Restorative proctocolectomy with ileopouch-anal anastomosis (IPAA) is the treatment of choice for intractable or complicated ulcerative colitis (UC). Debate exists concerning outcomes of IPAA in the elderly and literature data are scarce. We report our experience of IPAA in older population. METHODS: We gathered data on a prospective database of patients undergoing IPAA for UC over 70 years of age in our Unit from January 1990 through January 2010. Patients were compared with randomly selected younger controls on a 1:3 ratio. Patients underwent IPAA in 2 or 3 stages. Demographical data, disease characteristics, comorbidities, concomitant medications, peri-operative management, intra- and post-operative complications were analyzed. Function and quality of life were assessed by clinical visit and Inflammatory Bowel Disease Questionnaire 1 and 3 years after ileostomy takedown. RESULTS: Twenty-seven elderly patients underwent IPAA for UC in the study period; these were compared with 81 younger controls. The former had more comorbidities and higher ASA score. All patients underwent loop-ileostomy closure. There were no differences between groups concerning the rate of major complications, but elderly patients more frequently had nuisances due to stoma output. Younger patients experienced significantly more episodes of small bowel obstruction. No significant differences in bowel control and health-related quality of life was observed, except for an higher rate of elderly patients taking antidiarrhoeals at 1-year follow-up; this observation was not confirmed at 3-year follow-up. A minimal decrease in continence was observed, but this did not affect overall satisfaction. CONCLUSIONS: IPAA can be safely offered to selected elderly UC patients who are strongly motivated and with no clinical disturbances of continence. In experienced hands no differences are likely to be expected concerning complications, quality of life and function. Results are stable with time and comparable to those of younger patients.

BACKGROUND: Perioperative prophylactic antibiotic treatment significantly influences intestinal microflora, resulting in impaired bowel functioning in some patients, sometimes requiring further investigations. This may lead to a worse health-related quality of life (HRQoL). Probiotics administrated in the early post-operative period may help avoiding such nuisances in older people. METHODS: We prospectively enrolled patients undergoing laparoscopic colorectal surgery aged over 70 years between 2005 and 2012. The study was approved by IRB. All patients received perioperative antibiotic treatment. Patients were randomized to one of two treatment arms: Group A patients received probiotics after surgery (VSL#3, VSL Pharmaceuticals, Inc. USA - 900 × 109 daily, while Group B patients received a Placebo (cornstarch). Patients were further divided in sub-groups whether ileo-caecal valve was spared or not. Patients were followed-up every 7 days for 4 weeks. Patients daily annotated bowel frequency, stool shape and consistency - according to Bristol's scale. HRQoL was assessed every week by means of SF-36 questionnaire. RESULTS: Group A included 10 while Group B included 8 patients. One patient in each group experienced a postoperative complication. Group A patients had fewer bowel movements than controls, during every week. Stool consistency was higher in patients undergoing resections including ileo-caecal valve receiving VSL#3. HRQoL gradually increased in both groups; Group A patients had higher "social functioning" item scores at week 1 and 4 than controls. CONCLUSIONS: Elderly patients undergoing resection of ileo-caecal valve may benefit from an early probiotics administration pathway after perioperative antibiotic treatment.

BACKGROUND: Artificial Intelligence (AI)-based analysis represents an evolving medical field. In the last few decades, several studies have reported the diagnostic efficiency of AI applied to Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) to early detect liver metastases (LM), mainly from colorectal cancer. Despite the increase in information and the development of different procedures in several radiological fields, an accurate method of predicting LM has not yet been found. This review aims to compare the diagnostic efficiency of different AI methods in the literature according to accuracy, sensibility, precision, and recall to identify early LM. METHODS: A narrative review of the literature was conducted on PubMed. A total of 336 studies were screened. RESULTS: We selected 17 studies from 2012 to 2022. In total, 14,475 patients were included, and more than 95% were affected by colorectal cancer. The most frequently used imaging tool to early detect LM was found to be CT (58%), while MRI was used in three cases. Four different AI analyses were used: deep learning, radiomics, machine learning, and fuzzy systems in seven (41.18%), five (29.41%), four (23.53%), and one (5.88%) cases, respectively. Four studies achieved an accuracy of more than 90% after MRI and CT scan acquisition, while just two reported a recall rate ≥90% (one method using MRI and CT and one CT). CONCLUSIONS: Routinely acquired radiological images could be used for AI-based analysis to early detect LM. Simultaneous use of radiomics and machine learning analysis applied to MRI or CT images should be an effective method considering the better results achieved in the clinical scenario.
RESUMEN
BACKGROUND: The gastroesophageal reflux disease (GERD) worldwide prevalence is increasing maybe due to population aging and the obesity epidemic. Nissen fundoplication is the most common surgical procedure for GERD with a failure rate of approximately 20% which might require a redo surgery. The aim of this study was to evaluate the short- and long-term outcomes of robotic redo procedures after anti-reflux surgery failure including a narrative review. METHODS: We reviewed our 15-year experience from 2005 to 2020 including 317 procedures, 306 for primary, and 11 for revisional surgery. RESULTS: Patients included in the redo series underwent primary Nissen fundoplication with a mean age of 57.6 years (range, 43-71). All procedures were minimally invasive and no conversion to open surgery was registered. The meshes were used in five (45.45%) patients. The mean operative time was 147 min (range, 110-225) and the mean hospital stay was 3.2 days (range, 2-7). At a mean follow-up of 78 months (range, 18-192), one patient suffered for persistent dysphagia and one for delayed gastric emptying. We had two (18.19%) Clavien-Dindo grade IIIa complications, consisting of postoperative pneumothoraxes treated with chest drainage. CONCLUSION: Redo anti-reflux surgery is indicated in selected patients and the robotic approach is safe when it is performed in specialized centers, considering its surgical technical difficulty.

Retroperitoneal ganglioneuroma is a rare neuroectodermal tumor with a benign nature. We performed a literature review among 338 studies. We included 9 studies, whose patients underwent CT and/or MRI to characterize a retroperitoneal mass, which was confirmed to be a ganglioneuroma by histologic exam. The most common features of ganglioneuroma are considered to be a solid nature, oval/lobulated shape, and regular margins. The ganglioneuroma shows a progressive late enhancement on CT. On MRI it appears as a hypointense mass in T1W images and with a heterogeneous high-intensity in T2W. The MRI-"whorled sign" is described in the reviewed studies in about 80% of patients. The MRI characterization of a primitive retroperitoneal cystic mass should not exclude a cystic evolution from solid masses, and in the case of paravertebral location, the differential diagnosis algorithm should include the hypothesis of ganglioneuroma. In our case, the MRI features could have oriented towards a neurogenic nature, however, the predominantly cystic-fluid aspect and the considerable longitudinal non-invasive extension between retroperitoneal structures, misled us to a lymphatic malformation. In the literature, it is reported that the cystic presentation can be due to a degeneration of a well-known solid form while maintaining a benign character: the distinguishing malignity character is the revelation of immature cells on histological examination.
RESUMEN
BACKGROUND: Ileoanal pouch related fistulae (PRF) are a complication of restorative proctocolectomy often requiring repeated surgical interventions and with a high risk of long-term recurrence and pouch failure. AIMS: To assess the incidence of PRF and to report on the outcomes of available surgical treatments. METHODS: A PRISMA-compliant systematic literature search for articles reporting on PRF in patients with inflammatory bowel diseases (IBD) or familial adenomatous polyposis (FAP) from 1985 to 2020. RESULTS: 34 studies comprising 770 patients with PRF after ileal-pouch anal anastomosis (IPAA) were included. Incidence of PRF was 1.5-12%. In IBD patients Crohn's Disease (CD) was responsible for one every four pouch-vaginal fistulae (PVF) (OR 24.7; p=0.001). The overall fistula recurrence was 49.4%; procedure-specific recurrence was: repeat IPAA (OR 42.1; GRADE +); transvaginal repair (OR 52.3; GRADE ++) and transanal ileal pouch advancement flap (OR 56.9; GRADE ++). The overall failure rate was 19%: pouch excision (OR 0.20; GRADE ++); persistence of diverting stoma (OR 0.13; GRADE +) and persistent fistula (OR 0.18; GRADE +). CONCLUSION: PVFs are more frequent compared to other types of PRF and are often associated to CD; surgical treatment has a risk of 50% recurrence. Repeat IPAA is the best surgical approach with a 42.1% recurrence rate.

BACKGROUND: Diabetes Mellitus (DM) may occur in IBD and influence the disease progression. AIM: To compare disease course and treatment outcomes in IBD patients with and without DM. METHODS: This is a systematic review with meta-analysis comparing patients with IBD plus DM with patients with IBD only. PRIMARY ENDPOINTS: need for surgery, IBD-related complications, hospitalizations, sepsis, mortality. Quality of life and costs were assessed. RESULTS: Five studies with 71,216 patients (49.1% with DM) were included. Risk for IBD-related complications (OR=1.12, I2 98% p = 0.77), mortality (OR=1.52, I2 98% p = 0.37) and IBD-related surgery (OR=1.20, I2 81% p = 0.26) did not differ. Risk of IBD-related hospitalizations (OR=2.52, I2 0% p < 0.00001) and sepsis (OR=1.56, I2 88% p = 0.0003) was higher in the IBD+DM group. Risk of pneumonia and urinary tract infections was higher in the IBD+DM group (OR=1.72 and OR=1.93), while risk of C. Difficile infection did not differ (OR=1.22 I2 88% p = 0.37). Mean Short Inflammatory Bowel Disease Questionnaire score was lower in the IBD+DM group (38.9 vs. 47, p = 0.03). Mean health care costs per year were $10,598.2 vs $3747.3 (p < 0.001). CONCLUSION: DM might negatively affect the course of IBD by increasing the risk of hospitalization and infections, but not IBD-related complications and mortality.

BACKGROUND: Restorative proctocolectomy with ileopouch-anal anastomosis (IPAA) is the treatment of choice for intractable or complicated ulcerative colitis(UC). Elderly patients often present with acute colitis requiring emergent subtotal colectomy(SC). Frail patients are at risk of developing septic complications related to the closed rectosigmoidal stump, often requiring formation of a second stoma to be reversed at the time of completion proctectomy. This carries nuisance to such exhausted patients. We propose a simple and inexpensive trick to avoid the need for creating a mucous fistula. METHODS: IPAA was performed as a 3-stage procedure in emergency settings. The rectosigmoidal stump was closed and placed subcutaneously; skin was closed over it. After SC, if patients showed signs of stump-related pelvic sepsis, a lavage of the rectal stump with povidone iodine solution and with saline was carried out as a rescue treatment aiming to avoid the need of opening the rectal stump to drain sepsis. RESULTS: Thirty-five patients underwent SC for UC between 1987 and 2012. The skin was closed over the closed stump in the 20. Seven patients out of these 20 experienced early stump-related septic complication. In five cases, we were able to avoid opening of the rectal stump, and a second stoma was unnecessary. After opening the closed stump in the remaining ones, a prompt improving of symptoms was observed. CONCLUSIONS: Rectal washout was well tolerated and avoided a second stoma in five out of seven patients, with better quality of life and body perception after IPAA surgery. This is relevant when dealing with geriatric patients, needing to completely recover before undergoing completion proctectomy.

BACKGROUND: External rectal prolapse (ERP) is a debilitating condition in which surgery plays an important role. The aim of this study was to evaluate the outcomes of abdominal approaches (AA) and perineal approaches (PA) to ERP. METHODS: This was a PRISMA-compliant systematic review with meta-analysis. Studies published between 1990 and 2021 were retrieved. The primary endpoint was recurrence at the last available follow-up. Secondary endpoints included factors associated with recurrence and function. All studies were assessed for bias using the Newcastle-Ottawa Scale and Cochrane tool. RESULTS: Fifteen studies involving 1611 patients (AA = 817; PA = 794) treated for ERP were included, three of which were randomized controlled trials (RCTs; 114 patients (AA = 54; PA = 60)). Duration of follow-up ranged from 12 to 82 months. Recurrence in non-randomized studies was 7.7 per cent in AA versus 20.1 per cent in PA (odds ratio (OR) 0.29, 95 per cent confidence interval (c.i.) 0.17 to 0.50; P < 0.001, I2 = 45 per cent). In RCTs, there was no significant difference (9.8 per cent versus 16.3 per cent, AA versus PA (OR 0.82, 95 per cent c.i. 0.29 to 2.37; P = 0.72, I2 = 0.0 per cent)). Age at surgery and duration of follow-up were risk factors for recurrence. Following AA, the recurrence rates were 10.1 per cent and 6.2 per cent in patients aged 65 years and older and less than 65 years of age, respectively (effect size [e.s.] 7.7, 95 per cent c.i. 4.5 to 11.5). Following PA, rates were 27 per cent and 16.3 per cent (e.s. 20.1, 95 per cent c.i. 13 to 28.2). Extending follow-up to at least 40 months increased the likelihood of recurrence. The median duration of hospital stay was 4.9 days after PA versus 7.2 days after AA. Overall, incontinence was less likely after AA (OR 0.32), but constipation occurred more frequently (OR 1.68). Most studies were retrospective, and several outcomes from RCTs were not consistent with those observed in non-RCTs. CONCLUSION: The overall risk of recurrence of ERP appears to be higher with PA versus AA. Incontinence is less frequent after AA but at the cost of increased constipation. Age at surgery and duration of follow-up are associated with increased risk of recurrence, which warrants adequate reporting of future studies on this topic.

The acute strangulation of internal hemorrhoids and the thrombosis of external hemorrhoids are both debilitating and painful conditions which require immediate treatment in order to minimize morbidity and reduce the length of inactivity. In selected cases, urgent surgical treatment, performed within 72 hours of presentation, prevents the negative economic and psychological effects of a prolonged recovery (which is often the case of conservative management), and limits the necessity for surgical intervention at a later date.

Hemorrhoidal Disease (HD) is widely diffused throughout the general population. The system of classification currently used to categorize this pathology is that of Goligher (1975). Several attempts in literature have been made to refine this classification, but as of yet, no single system has been universally accepted. Some studies, however, have succeeded in identifying specific characteristics, besides morphology, that would be able to aptly define HD. An analysis of the literature, with careful consideration of the scores that have previously been proposed, was performed, with the aim of deepening and stimulating discussion about a possible new definition of HD.

BACKGROUND: Colonic lipomas are rare and can sometimes cause intussusception. The aim of this review was to define the presentation and possible management for colocolic intussusception caused by colonic lipomas. METHODS: A systematic search for patients with colocolic intussusception caused by colonic lipoma, including all available reports up to 2021. Epidemiological, clinical, laboratory, and instrumental data and details about the treatments performed were gathered. RESULTS: Colocolic intussusception caused by lipoma is more frequent in women (57%), occurring between 40 and 70 years of age. Up to 83% of patients report abdominal pain, followed by constipation (18%), rectal bleeding (16%), and diarrhea (12%), with abdominal tenderness (37%), and distension in 16%, whereas 24% have a negative exploration. CT (72%) and colonoscopy (62%) are more commonly able to diagnose the entity. The most common location of intussusception is the transverse colon (28%). The surgical operation varies according to the site. The average dimensions of the lipoma are 59.81 × 47.84 × 38.9 mm3. CONCLUSIONS: A correct preoperative diagnosis of colonic lipoma causing intussusception might not be easy. Despite nonspecific clinical and laboratory presentation, cross-sectional imaging can help differential diagnosis. Surgical treatment depends on the localization.
RESUMEN
Preoperative staging represents a crucial point for the management, type of surgery, and candidacy for neoadjuvant therapy in patient with rectal cancer. The most recent clinical guidelines in oncology recommend an accurate preoperative evaluation in order to address early and advanced tumors to different therapeutic options. In particular, potential pitfalls may occur in the assessment of T3 tumors, which represents the most common stage at diagnosis. The depth of tumor invasion is known to be an important prognostic factor in rectal carcinoma; as a consequence, the T3 imaging classification has a substantial importance for treatment strategy and patient survival. However, the differentiation between tumor invasion of perirectal fat and mesorectal desmoplastic reactions remains a main goal for radiologists. Magnetic resonance imaging (MRI) is actually considered as the best imaging modality for rectal cancer staging. Although the endorectal ultrasound (ERUS) is the preferred staging method for early tumors, it could also be useful in identifying perirectal fat invasion. Moreover, the addiction of diffusion weighted imaging (DWI) improves the diagnostic performance of MRI in rectal cancer staging by adding functional information about rectal tumor and adjacent mesorectal tissues. This study investigated the diagnostic performance of conventional MRI alone, in combination with the DWI technique and ERUS in order to assess the best diagnostic imaging combination for rectal cancer staging.
