Lift and VAAFT for high trans-sphincteric anal fistula: a single center retrospective analysis.

PURPOSE: The management of complex anal fistulas remains a challenge, mainly due to the considerable risk of incontinence. We compared LIFT and VAAFT in the treatment of complex anal fistulas in terms of healing time, recurrence, continence, morbidity, and postoperative pain, focusing also on patients with local abscess at the time of surgery. METHODS: We include all patients with high trans-sphincteric anal fistula even with abscess at the time of surgery. Anorectal manometry, endoanal ultrasound, Cleveland Clinic fecal incontinence score, VAS score, and number of previous fistula treatment were recorded. The clinical examination defined healing, insufficiency or recurrence of the fistula. RESULTS: Fifty-four consecutive patients are undergoing surgery: 26 patients underwent LIFT and 28 underwent VAAFT. During the 18 months of follow-up there were no differences in terms of AM, CCFIS and VAS scores. Days of healing, failure, and recurrence rate were comparable in both groups. The subgroup of patients with local abscess undergoing LIFT showed worse results in terms of failure and recurrence rate (p < 0.05). CONCLUSIONS: Both techniques are safe and effective and can offer long-term benefits. LIFT should not be used as a first treatment in high trans-sphincteric fistula with perianal abscess.

Conservative surgical treatment in rectal cancer after complete pathological response to neoadjuvant treatment. Prospective observational study.

In 2012 we started a prospective observational study at San Giovanni Addolorata Hospital in Rome for patients with rectal cancer with complete response to neoadjuvant therapy (nCRT). In our, IRB approved protocol, patients are evaluated at time 0 by physical, endoscopic, pathological and radiological examinations. 6 weeks after completion of nCRT they are re-evaluated. In case of persistence or progression of disease patients undergo surgery with Total Mesorectal Excision. In case of complete or major clinical response they are re-evaluated at 12 weeks and subjected to transanal surgical excision to confirm complete pathological response (pCR). If tumor is found in the transanal excision specimen the patient is operated upon whereas patients with pCR are followed up at 3 months interval.

Radioguided surgery with combined use of gamma probe and hand-held gamma camera for treatment of papillary thyroid cancer locoregional recurrences: a preliminary study.

BACKGROUND: Persistent differentiated papillary thyroid cancer (PTC) with metastasis followed by radical locoregional surgery is an indication for limited reoperation. Despite excellent prognosis the major challenge is controlling locoregional recurrences. AIM: To evaluate the efficacy of radioguided excision with combined use of gamma probe and an hand-held gamma camera. PATIENTS AND METHODS: From June 2009 to January 2012, we enrolled twenty-two patients with locoregional PTC recurrences, previously undergone to central and/or lateral neck dissection for PTC. The diagnosis of recurrent PTC was based on thyroglobulin (TG) evaluation [basal and after thyroid stimulating hormone (TSH) stimulation], ultrasound (US), iodine-131 (131I) whole body scan (WBS) and fine needle aspiration cytology (FNAC). In the morning of surgery, radiotracer was injected directly into the lesions by US guide. Careful dissection was carried out using gamma probe and hand held gamma camera. Metastatic lymph nodes were identified and excised. RESULTS: In all the patients recruited, 39 pathologic nodes were injected and 61 nodes were removed. Among the removed nodes, 22 (36.1%) were additional nodes (not injected by radiotracer). Of the additional lymph nodes, 7 (31.8%) were metastatic. Mean radioactive count of the lesion (28.633±9.218 counts/s) was higher than tumor bed (385.73±192.23 counts/s) (p < 0.0001). No complications were observed during radioguided excision, neither on post-operative period. CONCLUSIONS: The use of hand-held gamma camera in addition to gamma probe in our preliminary study allows a minimally invasive procedure and safer identifications of the lesions and ensures the completeness of the excision in a difficult surgical field.

Renal artery embolization in a gross kidney neoplasm. Case report.

AIM: To demonstrate the utility of the renal artery embolization (RAE) in the dissection of gross neoplasms and the reduction in blood loss and operative time. CASE REPORT: We report a case of a gross left renal neoplasm (with the diameter of about 12 cm) in a 45 years old Caucasian female who underwent to renal artery embolization 24 hours before left nephroureterectomy. This procedure has determined a reduction in operative times (about 90 minutes) because of the ligature of the renal vein was facilitated. Intraoperative blood loss was of about 100 ml and the patient didn't need of blood transfusions; the abdominal drain was removed in third postoperative day (daily drained serous fluid was about 20 ml). The patient was discharged 7 days later. CONCLUSION: RAE facilitates the dissection of gross neoplasms (diameter> than 10 cm), so causing a reduction in intraoperative blood loss and in blood transfusion. The operative times are lower because the ligature of the renal vein is less difficult and the dissection is facilitated for the presence of tissue oedema. The disadvantages are the incomplete hembolyzation, coil migration, hematomes, post-infarction syndrome (nausea, vomit, abdominal pain, leucocytosis, hyperpyrexia, hematoma); other risks include the possibility of pulmonary embolism, intestinal infarction and infections. Its reduced utilization could be due to the lack of randomized prospective studies showing its potential benefits.

Minimally invasive video-assisted thyroid surgery: how can we improve the learning curve?

OBJECTIVE: Minimally invasive video-assisted thyroidectomy (MIVAT) is a technically demanding procedure and requires a surgical team skilled in both endocrine and endoscopic surgery. A time consuming learning and training period is mandatory at the beginning of the experience. The aim of our report is to focus some aspects of the learning curve of the surgeon who practices video-assisted thyroid procedures for the first time, through the analysis of our preliminary series of 36 cases. PATIENTS AND METHODS: From September 2004 to April 2005 we selected 36 patients for minimally invasive video-assisted surgery of the thyroid. The patients were considered eligible if they presented with a nodule not exceeding 35 mm in maximum diameter; total thyroid volume within normal range; absence of biochemical and echographic signs of thyroiditis. We analyzed surgical results, conversion rate, operating time, post-operative complications, hospital stay, cosmetic outcome of the series. RESULTS: We performed 36 total thyroidectomy. The procedure was successfully carried out in 33/36 cases. Post-operative complications included 3 transient recurrent nerve palsies and 2 transient hypocalcemias; no definitive hypoparathyroidism was registered. All patients were discharged 2 days after operation. The cosmetic result was considered excellent by most patients. CONCLUSIONS: Advances in skills and technology have enabled surgeons to reproduce most open surgical techniques with video-assistance or laparoscopically. Training is essential to acquire any new surgical technique and it should be organized in detail to exploit it completely.

[Acute abdomen in renal transplant recipients. Epidemiology and treatment in not referral transplantation centers]. / L'addome acuto nel paziente trapiantato renale. Considerazioni epidemiologiche, diagnostiche e terapeutiche in DEA non dedicati.

The incidence of gastrointestinal complications in renal transplant recipients is relatively high while about 10% is related to acute abdomen. Data concerning gastrointestinal (GI) complications were reported in literature mainly from referral center studies. A multicenter retrospectively survey was performed in Lazio, Italy, in order to evaluate the incidence of acute abdomen in renal transplant recipients observed to the emergency departments of not referral transplantation centers. Clinical and demographic findings regarding 14 patients who experienced acute abdomen between February 2005 and Dicember 2008 have been collected. The following data was investigated: etiology, diagnostic workup, duration of symptoms, elapsed time between admission and emergency operation if performed, morbility and mortality. The severity of disease at presentation was assessed by mean of the Acute Physiology and Chronic Health Evaluation score (APACHE II). Acute abdomen was due to pancreatitis in three patients (23.1%); to cholecystitis in three (23.1%); to acute diverticolitis with colon perforation in two patients (15.4%); to acute appendicitis in two (15.4%) and to intestinal obstruction in 2 patients (15.4%). Small bowel perforation was observed in two patients (15.4%) which one case, upon pathological examination, showed malignant lymphoma. The mean APACHE II score was 14.0 ± 5.9. Ten patients (71.4%) were submitted to surgery. Overall mortality and morbidity were 35% and 42% respectively. Statistical analysis showed admission APACHE II score (p<0.01), duration of symptoms (p<0.05), and total time elapsed between the onset of symptoms and treatment (p<0.04) as factors significantly related to mortality.
