RESUMO

PURPOSE: The use of minimally invasive groin hernia repair techniques in an emergency setting is still debated and its widespread is limited. The aim of this study is to evaluate the safety and efficacy of the laparoscopic transabdominal preperitoneal (TAPP) technique in the treatment of inguinal and femoral hernias in emergency setting based on our experience, comparing indications and outcomes with the open technique. METHODS: A retrospective analysis was performed including all patients with incarcerated and/or strangulated groin hernia who underwent emergency surgery from November 2019 to September 2022. Perioperative variables and short- and long-term outcomes were examined. Statistical analysis was performed using chi-square test for nominal variables and Student's t test for continuous ones. A p value < 0.05 was considered statistically significant. RESULTS: Sixty-six patients were included: 29 patients were treated with TAPP technique (Tapp group) and 37 with open technique plus diagnostic laparoscopy (Open group). Patients in the TAPP group were younger, had less severe clinical scenarios, and had a trend for lower Charlson Comorbidity Index, whereas ASA score and BMI were similar. The small bowel was more frequently herniated in the open group. Bilateral hernia repair was performed in 20.69% of patients in the Tapp group versus 0% in the Open group (p = 0.004). Bowel resection was more frequent in the open group (48.65% vs 0% of the Tapp group, p < 0.001) length of surgery was comparable in the two groups. In the Tapp group, the length of hospitalization was significantly shorter (2.59 ± 2.28 days vs. 9.08 ± 14.48 days; p = 0.023). Postoperative complications, according to Clavien-Dindo, were more severe in Open group where there were two deaths. There were no differences in the number of readmission and re-operations at 30 days and in the recurrence rate. CONCLUSIONS: Emergency repair of inguinal and femoral hernias using TAPP is a valuable option, safe and feasible in selected patients. In this series, indications for TAPP were reserved to younger patients with less comorbidities and less severe clinical scenario. Future randomized studies are needed to compare TAPP with open emergency hernia surgery in all settings. Potential advantages of TAPP are the reduction of postoperative complications, earlier recovery, and the possibility of bilateral treatment.

RESUMO

BACKGROUND: Minimally invasive video-assisted thyroidectomy (MIVAT) has been introduced into clinical practice by Miccoli in the late 1990s (Miccoli et al., Am J Surg 181(6):567-570, 2001) and it has become a widespread technique used and welcomed worldwide. In this paper, we present our experience of the last 2 years; we also describe tips and techniques derived from over 460 cases performed in the last 10 years by the same surgical team with the same single operator. METHODS: In the last 10 years, we did about 460 MIVAT procedures. In the last 2 years, we performed MIVAT on 156 consecutive patients at Sant'Andrea University Hospital of Rome "Sapienza" University. of 156 cases performed, we were able to monitor the follow-up in 110 patients. RESULTS: On 110 cases, the mean surgical time was 74 ± 7.2 min. In our data, we reported: transitory hypoparathyroidism 11 (10%), definitive hypoparathyroidism 4 (3.60%) (this value is inclusive of patients treated with central neck dissection. The value referred only to MIVAT is 1.05%), 2 (1.81%) transitory monolateral nerve palsy, 16 (14.50%) transitory, and 1 (0.9%) definitive nerve palsy. 4 (3.60%) cases of transitory dysphagia and 0 (0%) cases of definitive dysphagia (Table 4). We also had 1 (0.9%) case of surgical scar infection, 0 (0%) postoperative bleeding, and 2 (1.81%) cases of subcutaneous surgical adhesion. Cosmetic results were: 0 (0%) insufficient, 0 (0%) sufficient, 6 (6.30%) passable, 17 (15.50%) good. and 86 (78.20%) excellent. Conversion rate 0 (0%). CONCLUSION: MIVAT is a good and safe technique, with similar short-term outcomes and similar costs compared to traditional total thyroidectomy. We hope that the tips and techniques reported in this paper as well as the advices in the use of instruments in MIVAT and open surgery will be useful to improve the skills of young surgeons and make thyroid surgery less invasive.

RESUMO

BACKGROUND: Patients requiring ventral hernia (VH) repair during perioperative chemotherapy have a higher risk for post-operative complications. The aim of the study was to perform a case-controlled analysis in patients undergoing chemotherapy who underwent VH repair using biological mesh or synthetic mesh. METHODS: From January 2013 to December 2015, 32 patients, within 8 weeks from chemotherapy administration, were treated electively for VH repair using a biological mesh (BIOMESH). A control group (CG) receiving chemotherapy within the same time interval and treated with synthetic meshes was selected. There were no differences regarding sex, age, American Society of Anesthesiologists (ASA) score III, BMI, and size of the defect. Morbidity, type of complications, and recurrence rate were investigated and compared between the two groups. RESULTS: In the BIOMESH group, eight patients (25 %) experienced complications. Wound dehiscence occurred in four (12.5 %) patients and was treated conservatively. Only three small seromas not requiring treatment were observed. The CG presented a higher mean Clavien-Dindo complication grade (1.94 ± 0.44 vs 1.63 ± 0.52; p = 0.13) and a higher incidence of wound dehiscence (n = 9/32, 28.1 % vs n = 4/32, 12.5 %; p = 0.11). Five patients developed seroma treated by wound drainage. One patient experienced an intra-abdominal collection treated by percutaneous drainage. At the univariate and multivariate analysis use of traditional mesh, BMI and the ASA III were predictive factors of post-operative complications. Two patients (6.3 %) developed a VH recurrence only in the CG. CONCLUSIONS: Biological meshes could be considered a valid option to improve post-operative short-term outcomes in selected high-risk patients undergoing chemotherapy treated for VH repair.

RESUMO

AIM: For a few years, teledentistry has been an emerging innovative strategy with potential in the field of paediatric dentistry. There are still few studies in this regard, so further research is needed to verify and ensure that teledentistry is not only an accessible mode of communication, but above all effective and evidence-based. This study aimed to use a preliminary telematic approach to promote the compliance of patients in the developmental age during the first dental visit. MATERIALS: Two hundred patients were selected according to the eligibility criteria, and distributed in two groups: a study group with the preliminary telematic approach (ATP) before the first visit and a control group with traditional first visit without ATP. Through an ordinal semi-proportional regression model, the degrees of collaboration between the study and control groups were compared, correcting the estimate for age groups, the presence of systemic pathologies, disorders of cognition, attention and learning, degree of anxiety and previous medical-dental experiences. CONCLUSION: The preliminary telematic approach could be useful as a support to the traditional paediatric dental visit, to promote better management and fidelity of the patient, reducing anxiety and increasing collaboration during the first visit.

RESUMO

AIM: Patients at development age show considerable attention to the shape of the face from both an aesthetic and relational point of view, to arouse interest from researchers. There are few studies related to profile analysis in patients of developmental age. Therefore, the objective of the present study was to analyse the importance of the aesthetic perception of the patient in development age in relation to the profile, before and after interceptive orthodontic treatment. MATERIALS: A sample of 25 patients who came to our observation for dentoskeletal malocclusions was considered. A questionnaire was proposed to each patient, before and after the interceptive orthodontic treatment (T0 and T1), to evaluate the aesthetic perception before and after the orthodontic treatment and its psychosocial impact. Profile analysis was performed using photographic documentation (at T0 and T1). The variables considered were the Ricketts line, the facial convexity angle, the nasolabial angle, and the labiomental angle. CONCLUSION: Interceptive orthodontic treatment has proven to be of valid clinical and psychological help. This result is confirmed by the complete aesthetic satisfaction of the patient in the frontal and latero-lateral planes.

RESUMO

AIM: To analyse lifestyle of Italian families during lockdown, evaluating its possible impact on the collaboration of children with the paediatric dentist and associated predictive factors. MATERIALS AND METHODS: Only patients aged between 3 and 16 years, who had started treatment before the lockdown and had spent this periodwith both parents were included in the study. The interviews were carried out using an anonymous questionnaire that assessed school and play activities, the type of diet, the time dedicated to home oral hygiene and the activities carried out with parents. Parents' work situation during lockdown was included to correlate it with time spent at home. The Frankl Behavior Rating Scale was used to determine the degree of cooperation during dental sessions pre- and post-lockdown. Chi-square test and Fisher's Exact tests were used to identify statistical associations of improvement with each categorical variable. Student's t-test was used to highlight the differences in mean values of continuous variables between subjects considered more cooperative and unimproved subjects. Hosmer-Lemeshow test was used to assess the goodness-of-fit of the model. Assumption of linearity of independent variables and log-odds were assessed by Box-Tidwell transformation. Final selection was carried out using the Akaike criterion and all statistical analyses were carried out using the STATA statistical software package. RESULTS: The sample consisted of 212 patients (103F; 109M). The age ranged between 3 and 16 years with an average age of 9.03 years; 82.08% (95% CI 76.24-86.99) of the subjects showed an improvement in collaboration compared to pre-lockdown. Logistic analysis reveals a statistically significant increase of the odds of improvement in patients with a lower pre-lockdown collaboration (OR: 6.05, p = 0.001), in children with a parental presence at home (jobless, OR : 30.55, p <0.001; in "smart working", OR: 23.06, p <0.001) when compared to children whose parents work away from home. From a further exploratory analysis, time dedicated to home oral hygiene was increased if associated with an increased presence of the parents at home (p = 0.015). CONCLUSION: Changes in family routines and increased parental presence at home, during the COVID-19 pandemic lockdown, are associated with improved collaboration of children during dental sessions. A statistical association between the increase in time spent on oral hygiene and the increased presence of parents at home was found.

RESUMO

Fournier's gangrene is a life-threatening acute necrotizing fasciitis of perianal, genitourinary and perineal areas. Local symptoms are scrotal swelling, erythema of scrotal skin and pain with generalized constitutional symptoms. The gangrene may extends to abdominal wall, intra-abdominal structures, and even in the retroperitoneal tissues. Urgent surgical debridement is crucial to warrant a good outcome since delayed intervention carries a poor prognosis. We report the case of a not diabetic patient with Fournier's disease presented with severe sepsis and successfully treated with urgent deep debridement and reconstructive surgery. We propose the social status of the patient as a prognostic factor with high impact for survival rate.

RESUMO

OBJECTIVES: Intra-articular corticosteroids injection (IAC) is a mainstay for the treatment of children with chronic arthritis; nonetheless its efficacy showed variability among published studies and it is still not possible to predict the outcome in a single patient. Our objective was to study the profile of biomarkers in the synovial fluid (SF) obtained at the time of injection and establish if such profile predicts duration of effect. METHODS: SF obtained from patients who underwent knee arthrocentesis and injection was procured and stored for cytokine analysis. Records of those patients who had at least 6 months of follow-up from the injection were reviewed. Time to flare was recorded. Levels of IL-6, IL-1alpha, TNF-alpha, IL-2sR, MMP-3, IL-10 and TGF-Beta1 were measured by ELISA. For primary analysis each patient was utilized once. For secondary analysis each injected knee was considered a single event. RESULTS: 60 samples from 33 patients were obtained. In the primary analysis we found a correlation between MMP-3 synovial fluid levels and outcome at 6 months (p=0,02; p=0,03 for different quartiles). In the secondary analysis we found that IL-6 and IL-10 levels predicted outcome at six and at 12 months (IL-6: p=0.01; p=0.02 respectively) (IL-10: p=0.017; p=0.01 respectively), with higher levels of IL-6 predicting shorter time to relapse and higher levels of IL-10 longer duration of corticosteroids effect. CONCLUSIONS: Our study identified MMP-3 and possibly IL-6 and IL-10 as candidates for the development of a set of biomarkers to predict response to IAC among children with chronic arthritis at the time of injection.

RESUMO

AIM: Aim of the study was to evaluate the operative time and the incidence of post-operative complications in a group of patients undergoing Lichtenstein inguinal hernia repair performed either by surgical residents or senior surgeons in a day-surgery setting. PATIENTS AND METHODS: The study population consisted of 198 patients: group I (n=102), in which the operator was a senior surgeon, group II (n=96), in which the operator was a resident supervised by a senior surgeon. We recorded the duration of the operation and the complications following the procedure, and statistically compared them between group I and II. RESULTS: Our analysis showed that there was a statistically significant difference between the two groups only for the mean operative time, being shorter in group I (62 vs 82 min, p>0.05), while no significant difference was found for the incidence of complications. CONCLUSION: In conclusion, the day-surgery setting allows a high quality training of young surgeons, based on performing minor surgical procedures such has inguinal hernia repair. This training allows a step by step supervised learning process that does not jeopardize the efficacy of the treatment as well as the patient safety. The major cost due to the increase in operative time should be considered as an investment in young surgeons education.

RESUMO

BACKGROUND: Local therapy with IL-2 may be very effective in the treatment of different forms of cancer. The aim of this study was to determine the effectiveness of IL-2 locoregional application in the treatment of colon cancer. MATERIALS AND METHODS: Twenty eight syngenic BDIX rats were utilized in this study. The rats were divided into two groups of fourteen animals: group T (treatment) and group C (control). All rats of both groups were injected, under the splenic capsule, with T 10(7) DHD/K2/ TRb neoplastic cells. Then, within and around the site of the previous inoculation, the T group was injected with 1 ml of glucosate solutions + 0.1% albumin (BSA) containing 2.5 x 10(6) IU of IL-2 ( Proleukin-Chiron), whereas the C group was injected with 1 ml of BSA alone. After three weeks, rats were sacrificed and the liver and spleen were removed. The following parameters were considered: volume and weight, neoplastic-non neoplastic tissue index of the spleen, mitotic index and vascular density of splenic and hepatic lesions. RESULTS: All the studied parameters showed statistically significant differences in treated and untreated animals. CONCLUSION: This study of a murine model demonstrated that IL-2 locoregional therapy may be effective in the treatment of colon cancer.

RESUMO

Intranodal palisaded myofibroblastoma (IPM) is a rare benign tumor of the lymph nodes probably arising from smooth muscle-like cells. The tumor is characterized by intranodal proliferation of spindle cells. Neoplastic spindle-cell proliferation is most often of metastatic repetition which is very important in the recognition of IPM, because it may be mistaken for metastasis or other tumors such as Kaposi's sarcoma. We report a novel case of IPM that confirms the myofibroblastic differentiation of the tumor. The onset of IPM has been associated with Epstein-Barr virus (EBV). In addition, recently reported cases of IPM have been seen with cyclin 1 overexpression and also with human herpes virus (HHV)-8 and EBV DNA sequences. In our case, there was no evidence of HHV-8 and EBV DNA sequences and we were not able to find cyclin 1 overexpression.

RESUMO

BACKGROUND: Abdominal aortic aneurysms (AAA) requiring surgical management are encountered more frequently in renal transplant recipients, presenting an important technical problem during the repair. The aim of the present study was to analyze the epidemiology and natural evolution of AAA among renal allograft recipients. METHODS: Three hundred ninety-four renal transplant recipients were periodically evaluated with abdominal aortic ultrasound tomography for AAA. The indication for surgery was a maximal diameter >5 cm. Renal function, graft, and patient survival were evaluated after a mean follow-up of 51 months. RESULTS: Four AAA were detected in 394 renal transplant recipients, a prevalence of 1.01%. All of the AAA were found in male recipients of mean age 59.2 +/- 5.5 years and mean time posttransplantation of 82.7 +/- 77.3 months. The mean follow-up period between diagnosis and indication for surgery was 14.2 +/- 10.8 months. Two patients underwent open repair with aneurysmectomy and conventional tube graft positioning, and 2 patients refused surgical repair. To preserve renal graft function during the aortic cross-clamping phase, cold perfusion with 4 degrees C Ringer acetate and local hypothermia with sterile ice were used. Renal function did not change after the operation (preoperative serum creatinine levels were 1.2 and 1.3 mg/dL; postoperative 1.3 and 1.5 mg/dL respectively). The 2 patients who underwent surgery are alive with excellent graft functioning after a follow-up of 1.5 and 7 years, respectively. The 2 patients who refused surgical treatment are dead. CONCLUSIONS: Yearly ultrasound screening for AAA must be recommended in renal transplant recipients as part of the routine posttransplantation follow-up. De novo AAA occurs in younger subject in the transplant population and shows a faster evolution.

RESUMO

UNLABELLED: End-stage renal disease is associated with disorders in hypothalamic-pituitary-gonadal function. Immunosuppressive therapies may influence the restoration of normal levels of gonadal hormones after renal transplantation. The aim of the present study was to evaluate the hormonal status of successful renal transplant recipients who were treated with different immunosuppressive agents. METHODS: Testosterone, luteinizing hormone (LH), and follicle stimulating hormone (FSH) were measured in 59 male renal transplant recipients with stable graft function with serum creatinine <2.5 mg/dL. Patients were treated with three different immunosuppressive regimens: group I, calcineurin inhibitors (CI; n = 15), group II, sirolimus without calcineurin inhibitors (SRL; n = 15), group III, sirolimus in combination with calcineurin inhibitors (SRL * CI; n = 29). RESULTS: Testosterone was significantly lower in group II versus group I (3.12 +/- 1.23 versus 4.39 +/- 1.53 ng/mL; P < .0197). Group III had higher testosterone values than group II, but lower than group I. FSH and LH were also higher in the SRL group, but the differences were not statistically significant, perhaps because of the small number of patients. No relationship was found between testosterone blood levels and age, posttransplant follow-up, renal function, time on dialysis, body mass index, steroid use, or posttransplant diabetes. CONCLUSION: Sirolimus seems to impair the improvement of gonadal function after renal transplantation. Further prospective studies are needed to confirm these data before patients are advised of this potential side effect.

RESUMO

Pools of ticks, Ixodes (Ceratixodes) uriae collected between 1975 and 1979 at Macquarie Island, yielded 33 strains of at least 4 different viruses: Nugget virus (Kemerovo group), 1 strain; Taggert virus (Sakhalin group) 9 strains; a previously undescribed flavivirus, related to Central European Tickborne encephalitis virus, for which the name "Gadgets Gully" is proposed, 9 strains; a virus serologically related to the Uukuniemi serogroup, family Bunyaviridae, for which the name "Precarious Point" is proposed, 10 strains. Three isolates were mixtures of Nugget and Gadgets Gully viruses; the remaining virus strain remains unidentified.

RESUMO

BACKGROUND: Advanced pancreatic cancer (APC) constitutes a poor-prognosis disease with few and disappointing therapeutic options. In recent years chemotherapy has demonstrated a positive effect on disease-related symptoms with the introduction of a novel pyrimidine analogue, gemcitabine. Moreover there is experimental and clinical evidence that endocrine therapy may play a small but unexplored role in the management of APC. Therefore we performed a phase II study to assess whether the combination of gemcitabine and tamoxifen could be an active and safe schedule for the treatment of APC in terms of response rate and clinical benefits. MATERIALS AND METHODS: Twenty-seven evaluable consecutive patients with locally advanced, unresectable or metastatic adenocarcinoma of the pancreas were treated with gemcitabine (1000 mg/mq given as a short infusion once weekly for 3 consecutive weeks out of every 4 weeks) and tamoxifen (20 mg daily starting the second day after gemcitabine). The treatment was continued until progression or unacceptable toxicity. Evaluation of efficacy included response rate, time to progression, survival and clinical benefit, an integrated measurement of pain parameters, weight and performance status. RESULTS: A partial response was achieved in 11% of patients while 48% experienced stable disease, lasting at least 8 weeks; disease progression was documented in 41% of patients. The median time of progression was 4.5 months; the median survival-time was 8 months and one-year survival was 31%. Clinical benefit was documented in 59% of patients with a median duration of 13 weeks. No gastrointestinal or haematological grade 4 toxicity was observed. In general the treatment showed a satisfactory safety profile and tamoxifen-related toxicity was not documented. CONCLUSION: The combination of gemcitabine and tamoxifen appears to be an innovative therapeutic approach in the management of APC with interesting clinical activity and a good profile of toxicity. This novel schedule of treatment deserves further investigation in large randomized trials to assess if the addition of tamoxifen could improve the therapeutic results of gemcitabine in APC, mostly in term of quality of lfe.

RESUMO

The authors present a case of ileocecocolic intussusception by carcinoma of the caecum. They stress the most peculiar aspects of this condition: rare etiology; complete invagination of caecum appendix and ileum; typical clinical presentation characterized by variable dimensions of the mass and symptoms not ascribing to occlusion, no lesions at endoscopy; evidence of a typical "target mass" visualized at T.C.

RESUMO

According to the literature and the personal experience of the authors there seem to exist many controversies on the treatment of pancreatic pseudocysts, partly due to the lack of definitions and to the fact that prognosis is different based upon the pathophysiology of the lesions. We report 4 cases of pancreatic pseudocysts successfully treated with a multidisciplinary approach, stressing the role of pharmacology and of artificial nutrition and endoscopy on the outcome of these lesions.

RESUMO

According to a clinic case, the authors pointed out the role of histological diagnosis in the therapeutic approach of large intestinal adenomas. In order to identify those lesions which can metastasize, having exceeded the muscularis mucosae and having invaded the submucosa, rigorous histological standards must be performed. Intestinal resection versus polypectomy is determined only according to the involvement or not of the muscularis mucosae.

RESUMO

The authors propose a jejunostomy on an omega loop distal to the Treitz ligament as a treatment for unresectable gastric lymphomas. The rationale is to provide nutritional support during chemotherapy in a situation when the stomach is defunctionalised. As assessed by clinical, morphological and biological parameters, the association of chemotherapy and jejunostomy may represent a valid therapeutical strategy for patients considered unresectable.
