Results of isolated infrapopliteal percutaneous transluminal angioplasty for critical limb ischemia in high-risk diabetic patients.

AIM: Infrapopliteal occlusive arterial lesions mostly characterize diabetic patients arteriopathy. Diabetic patients are prone to multiple comorbidities that make them candidates for low-invasive therapeutic options. The aim of this study was to evaluate the safety of infrapopliteal angioplasty in high-risk diabetic patients. METHODS: We undertook a study (retrospective study of a prospectively collected database) of all infrapopliteal endovascular revascularizations performed for critical limb ischemia in high-risk (≥3 major comorbidities) diabetic patients in our institution between 2008 and 2010. Study end points were safety, technical success rate, healing rate, overall 1-year survival, primary patency, secondary patency and limb salvage rates. RESULTS: A total of 101 high-risk diabetic patients (160 arterial lesions: 94 stenosis and 66 occlusions) underwent infrapopliteal endovascular surgery. No major adverse cardiovascular or cerebrovascular event was recorded within 30 days. Two major adverse limb events (two thromboses requiring major amputation) and seven minor adverse events were recorded. Technical and healing rates were, respectively, 83% and 78%. The 1-year survival, primary patency, secondary patency and limb salvage rates were, respectively, 86%, 67%, 83% and 84%. CONCLUSION: Infrapopliteal angioplasty can be considered as a safe and feasible option for high-risk diabetic patients with critical limb ischemia.

Chronic mesenteric ischemia: 20 year experience of open surgical treatment.

OBJECTIVES: Both open surgery (OS) and endovascular surgery (ES) have been proposed for the treatment of symptomatic chronic mesenteric ischaemia (CMI). OS was considered the gold standard but ES is increasingly proposed as the first option. The aim was to report long-term outcomes associated with OS in patients suffering CMI in the modern era in order to help in choose between the two techniques. MATERIALS AND METHODS: A retrospective single centre analysis of all consecutive digestive artery revascularizations performed for CMI between January 2003 and December 2012 was carried out. Primary outcomes were 30 day mortality and morbidity, and secondary outcomes were survival, primary patency (PP), secondary patency (SP), and freedom from digestive symptoms, depending on the completeness of the revascularization performed. RESULTS: Eighty-six revascularizations were performed. Median follow up was 6.9 years (range 0.3-20.0). The 30 day mortality and morbidity rates were respectively 3.5% and 13.9%. Ten year survival was 88% for complete revascularization (CR) and 76% for incomplete revascularization (IR) (p = .54). The PP was 84% at 10 years for CR and 87% respectively for IR (p = .51). The 10 year SP was 92% for CR and 93% for IR (p = .63). Freedom from digestive symptoms was influenced by the completeness of revascularization: 79% for CR versus 65% for IR at 10 years (p = .04). CONCLUSIONS: OS for CMI, especially complete revascularization, provides lasting results despite high morbidity.

Long-term outcomes of Madrid approach after TAR for complex abdominal wall hernias: a single-center cohort study.

PURPOSE: Undeniably, in the last 2 decades, surgical approaches in the field of abdominal wall repair have notably improved. However, the best approach to provide a durable repair with low morbidity rate has yet to be determined. The purpose of this study is to outline our long-term results following the Transverse Abdominis Release (TAR) approach in patients with complex ventral hernias, focusing on the incidence of recurrence and overall patient satisfaction following surgery. METHODS: This is a retrospective study on 167 consecutive patients who underwent TAR between January 2015 and December 2021 for primary or recurrent complex abdominal hernias. Of these, 117 patients who underwent the open Madrid approach with the use of a double mesh (absorbable and permanent synthetic mesh) were selected and analyzed. A quality of life questionnaire (EuraHS QoL) comparing the preoperative and the postoperative status was administered. RESULTS: Between January 2015 and December 2021, we successfully treated 117 patients presenting with complex ventral defects using the double mesh technique (absorbable and permanent synthetic mesh). Of these, 26 (22.2%) were recurrent cases. At a median follow-up period of 37.7 months, there had been 1 (0.8%) case of recurrence and 8 cases (6.8%) of bulging. The QoL score was significantly improved when compared to the preoperative status in terms of cosmesis, body perception, and physical discomfort. CONCLUSIONS: The Madrid approach for posterior component separation is associated with both a low perioperative morbidity and recurrence rate. In accordance with other studies, we demonstrated that the TAR with reconstruction according to the Madrid approach provides excellent results in the treatment of complex abdominal wall hernias, even at long-term follow-up.

HPV at the time of vaccine: has screening reached its goal?

INTRODUCTION: The human papillomavirus (HPV) prevalence recognized a geographic distribution of genotypes but, in the last years, the change of sexual behaviours, the increase number of sex partners, and the reduction of geographic distances have changed its prevalence and distribution. OBJECTIVE: To determine the prevalence of HPV types among females in the Molise region and its evolution in 24 months. MATERIALS AND METHODS: The authors, from February to August 2008, used a representative sample of a female population (n = 299) aged 17 to 64 years who were interviewed and submitted cervico-vaginal swab specimens. Swabs were analyzed for cytologic screening and HPV detection and typing. The patients with a positive cytology were submitted to colposcopy and eventually biopsy. Cytological and colposcopic follow up was performed in 24 months. RESULTS: The overall HPV prevalence was 30.1% and the prevalence of high- and low-risk HPV types was 22.41% and 18.06%, respectively. The prevalence of HPV vaccine types was relatively low for HPV-6-11-18. Only HPV-16 is well-represented in Molise, but recognizes a strictly geographic distribution. CONCLUSION: This study is one of the largest assessments of HPV genotypes to date in Italy. It is clear that several HPV-types are involved in cervical lesions, therefore the vaccine is profitable but limited by great number of types implicated in the pathogenesis of cancer and by their dishomogeneous distribution. Currently, a good campaign of screening is still necessary. In the future, second generation polyvalent HPV vaccines my be proposed for a wider and complete vaccine coverage.

Ischemic necrosis with sigmoid perforation in a patient with Systemic Lupus Erythematosus (SLE): case report.

Systemic Lupus Erythematosus (SLE) is a chronic inflammatory rheumatic disease which affects the connective tissue. Its etiology is as yet unknown, while its pathogenesis involves the immune system. Both genetic and environmental and hormonal factors play a key role in the impaired immune regulation. A correlation with estrogens is demonstrated by the fact that the greatest incidence is found in young women, when estrogen secretion is at its highest. The disease is also reported to worsen in women taking oral contraceptives. It is therefore believed that the components of oral contraceptives, estrogens (ethinyl estradiol) and progestins, can affect the immune profile. Of the various complications attributed to systemic lupus erythematosus, gastrointestinal disorders are less common but potentially by far the most serious. We report a case of ischemic necrosis with sigma perforation in a patient with SLE. Signs and symptoms of acute abdomen in patients with SLE are rare (0.2%), but serious. Most patients require an exploratory laparotomy, as the causes are often linked with vasculitis.

Surgical treatment of papillary thyroid carcinoma without lymph nodal involvement.

BACKGROUND: In the treatment of differentiated thyroid cancer (DTC), in absence of enlarged lymph nodes, the role of routine central lymph node dissection (RCLD) remains controversial. The aim of this study is to analyze data resulting from total thyroidectomy (TT) not combined with RCLD in the treatment of DTC. METHODS: We retrospectively evaluated the clinical records of 80 patients treated between January 1996 and December 2003 with TT without RCLND, in absence of suspected enlarged lymph nodes at preoperative ultrasonography and intraoperatively during neck exploration. In this series, 75 patients (93.7%) underwent radioiodine (RAI) ablation, followed by Thyroid Stimulating Hormone (TSH) suppression therapy. In case of locoregional lymph nodal recurrence, a central (VI) and ipsilateral (III-IV) selective lymph node dissection was performed. RESULTS: Incidence of permanent hypoparathyroidism (iPTH < 10 pg/ml) and unilateral temporary vocal fold paralysis were respectively 2.55% and 2.55%. Locoregional recurrence, with positive cervical lymph nodes, after a 10.3 ± 4.7 years mean follow-up was observed in 3 patients (3.75%). They were submitted to a central (VI) and ipsilateral (III-IV) selective neck dissection without significant complications. CONCLUSIONS: In our series, TT not combined with RCLD was associated to a low locoregional recurrence rate, even if the lack of a control group treated with RCLD does not allow any generalized assumption. RCLD may be indicated in high risk patients, in whom lymph nodal recurrence is more frequent. More prospective randomized studies are needed to better define the role of RCLD and postoperative radioiodine ablation.

Robotic transabdominal retromuscular rectus diastasis (r-TARRD) repair: a new approach.

PURPOSE: The aim of this study is to present our innovative robotic approach for the treatment of rectus diastasis with concurrent primary or incisional ventral hernias. METHODS: We performed 45 r-TARRD repairs for symptomatic rectus diastasis with concomitant associated ventral/incisional umbilical and/or epigastric hernias between January 2019 and January 2020. Data on patient demographics, type of hernia, operative time, complications, recurrence rate, and hospital stay were retrospectively analyzed. Follow-up was scheduled at 1, 6 months, and 1 year after surgery. RESULTS: 45 patients (13 M, 32 F) underwent r-TARRD repair. Mean age was 54.8 years (range 31-68) and mean BMI was 26.74 kg/m2 (range 21.1-31). Mean ASA was 2.2 (range 1-3). In all patients we used a polypropylene mesh 25 × 15 cm, properly shaped. Mean operative time was 192 min (range 115-260). Mean hospital stay 4.2 days (range 2-7). No conversion to laparoscopy or open surgery and no major complications occurred. At 1-month follow-up one mesh infection (2.22%) was observed and it was treated conservatively. Four recurrences (8.88%) were reported at 1-year follow-up. CONCLUSIONS: Robot-assisted TARRD repair is conceived as a novel alternative minimally invasive procedure for RD with concurrent midline defects ensuring a primary fascial defect closure and mesh implantation in a sublay position with a wide overlap. It is important to better evaluate the suture that should be used to perform the repair, and multicenter studies with standardization of patient's demographics, RD characteristics, and long-term follow-up outcomes are mandatory to assess the effectiveness and durability of r-TARDD repair.

The use of biosynthetic mesh in giant hiatal hernia repair: is there a rationale? A 3-year single-center experience.

PURPOSE: Reinforced prosthetic crural repair is particularly indicated for giant hiatal hernias. The rationale is to reduce the recurrence rate in the long term. The aim of our study is to evaluate the outcomes of laparoscopic giant hiatal hernia repair using a biosynthetic mesh. METHODS: We retrospectively analyzed 44 patients who underwent laparoscopic mesh-reinforced hiatal closure and fundoplication using a biosynthetic material. Inclusion criterion was large hiatal defects (> 5 cm). Follow-up was scheduled at 6, 12 and 36 months after surgery. RESULTS: 44 patients (29F) with a mean age of 62 years (range 14-85) and mean of BMI 24.5 kg/m2 (range 21-29) underwent successful laparoscopic repair. Twenty-six (59.1%) patients had Nissen-Rossetti fundoplication, whereas 18 (40.9%) had Toupet fundoplication. Six-month questionnaire for the evaluation of symptoms was available for 43 patients (97.7%) and for 40 (90.9%) patients at 12 and 36 months. Mean preoperative symptoms score analysis was 1.68 ± 0.73. Mean scores at each follow-up time were significantly improved compared to baseline (p > 0.05). Barium swallow was available in 37 patients (84.1%) at 1 year after surgery. Radiologic recurrence was observed in two patients (4.5%). No patient had symptoms attributable to recurrence or required revisional surgery. There were no mesh-related complications at 3 years follow-up. CONCLUSIONS: The use of biosynthetic mesh for crural reinforcement is associated with a low incidence of mesh-related complications and with a reasonably low recurrence rate (4.5%) at 36 months. However, additional data with longer follow-up are needed to determine long-term safety and efficacy.

Robotic-assisted single site (RASS) TAPP: an advantageous choice? : Outcomes of single site robotic groin hernia repair.

PURPOSE: Laparoscopic transabdominal preperitoneal (TAPP) is a valid option for bilateral primary groin hernia and recurrent cases. Robotic approach for inguinal hernia is still debated. The aim of this study is to investigate the potential role of robotic-assisted single site-TAPP (RASS-TAPP) reporting our experience. METHODS: We performed 44 RASS TAPP in 32 patients from February 2016 to July 2018. Data on patient demographics, type of hernia, operative time, complications, recurrence rate and hospital stay were retrospectively analyzed. Follow-up was scheduled at 1 week, 4 months and 1 year after surgery. RESULTS: Forty-two hernias were treated in 32 patients (27 M). Mean age was 48.6 years (range 20-67), mean BMI was 26.49 kg/m2 (range 16-34.9). Mean operative time was 54.8 min (range 28-150). In two cases (6%) a conversion to laparoscopy was necessary. At 1 week, two scrotal hematomas and four seromas were observed and treated conservatively. At 4 months follow-up, one patient (3.1%) complained temporary pain. No patient had inguinal recurrence or incisional umbilical hernia and chronic pain at 1-year follow-up. CONCLUSION: RASS TAPP is feasible and safe with a high patient satisfaction. However, the surgeon experiences a technical discomfort due to the conflict of the instrumentation which influences negatively the choice of this approach, despite the better vision and augmented dexterity provided by the robot.

The surgical management of acute bowel ischemia in octogenarian patients to avoid Short Bowel Syndrome: a multicenter study.

BACKGROUND: This is a multicenter study performed in two Italian tertiary care centers: General Emergency Surgery Unit at St. Orsola University Teaching Hospital - Bologna and Department of Surgical Sciences at Umberto I University Teaching Hospital - Rome. The aim was to compare the results of different approaches among elderly patients with acute bowel ischemia. METHODS: Sixty-three patients were divided in two groups: 1) DSgroup- 28 patients treated in Vascular Unit and 2) GEgroup- 35 patients treated in Emergency Surgery Unit. RESULTS: Mean age was 80 years, significantly higher for the GEgroup (p<0.001). Gender was predominantly female in both groups, without statistical difference. Pre-operatively, laboratory tests didn't show any difference in white blood cell count, serum lactate levels or serum creatinine among patients, while increase of c-reactive protein was observed in DSgroup with significant difference (p<0.001). The Romamain cause of acute bowel ischemia was embolism in DSgroup (p=0.03) and vascular spasm in GEgroup (p<0.001). On CT scan, bowel loop dilation was present in 58.7% of patients without statistical difference in both groups. The time lapse from diagnosis to operation didn't show significant differences between two groups (mean 349.4 min). Pre-operative heparin therapy was administered in DSgroup more frequently (p< 0.001). Among DS patients, thrombectomy was the most frequent procedure (19 patients) associated with bowel resection in 9 cases. In GEgroup, 22 patients had an explorative laparotomy (p<0.001), 8 had a bowel resection with anastomosis and 5 a bowel resection plus stoma. A second look was required more significantly in DSgroup (p<0.002). Post-operative morbidity affected significantly GEgroup (p=0.02). The 3-day survival was significantly higher in the DSgroup (p< 0.001). At discharge 32 patients (50.8%) were alive, 21 in DSgroup (p< 0.001). Only one patient among both groups (1.6%) developed a short bowel syndrome. CONCLUSIONS: In octogenarian patients with acute bowel ischemia, surgery should be always pursued whenever the interventional radiology is not assessed as a viable option. Both groups of patients showed an excellent outcome in terms of avoiding a short bowel syndrome. A multidisciplinary management by a dedicated team could offer the best results to prevent large intestinal resections.

Endometrial metastasis of a primitive neuroendocrine ovarian carcinoma: management and treatment of a case.

BACKGROUND: Neuroendocrine tumours are a heterogeneous group of separate clinico-pathological entities which have a common characteristic, i.e., expression of potential endocrine differentiation. In the ovary, the term "neuroendocrine" relates mainly to widely known carcinoids, but it may also be applied to rare neuroendocrine carcinomas as non-small cell type and small cell carcinomas of pulmonary type. In the literature only 11 cases of primary ovarian non-small cell neurendocrine carcinomas have been described and ten of these were associated with a surface epithelial ovarian tumour. Small cell neuroendocrine carcinoma of the ovary is a rare malignant tumour of the ovary. Advanced small cell carcinoma of the ovary is a very aggressive tumour with an overall poor prognosis and unfavourable outcome. CASE REPORT: The case reported is unique in the literature because the authors describe a rare case of endometrial metastasis of a primary ovarian non-small cell neurendocrine carcinoma without any surface epithelial ovarian tumour association. The tumour invaded up to less than half of the myometrium. The first symptoms were related to endometrial metastasis as metrorrhagia and pelvic pain while the asymptomatic presence of primary ovarian carcinoma was not acknowledged with physical examination, routine biochemistry, tumour markers, blood count and traditional transvaginal greyscale ultrasound. CONCLUSION: Magnetic resonance and three-dimensional (3D) ultrasonography with power Doppler are a great help in the diagnosis of ovarian localisation but only immunohistochemistry on histological material can provide a correct diagnosis. Immunohistochemistry expression of Ki67 is a useful marker of malignancy. Due to the rarity of this neoplasm, a general consensus for optimal treatment has yet to emerge. The reported biological aggressiveness of these tumours prompts combined treatment with radical surgery and adjuvant polychemotherapy.

Surgical approach to appendiceal mucocele mimicking an adnexal complex mass: case report.

Mucocele of the vermiform appendix is a rare disease of the appendix caused by mucoid substance retention in its lumen, due to obstruction or hyperproduction due to appendiceal retention cysts, mucosal hyperplasia, mucinous cystadenomas and cystadenocarcinomas. Therefore, also appendiceal malignancy can be the underlying cause, making accurate preoperative diagnosis imperative, even if this disease is often asymptomatic and an early diagnosis still remains very difficult on imaging studies. In women, appendiceal mucoceles can sometimes present on clinical and instrumental findings as a right adnexal mass mimicking an ovarian neoplasm. A rare case of appendiceal mucocele in a 36-year-old women with a right-sided painful pelvic mass is presented. The mucocele was misdiagnosed as a cystic complex mass of the right adnexa both clinically and ultrasonographically. Serum levels of CEA and CA19-9 were increased. Explorative laparoscopy was performed revealing an enlarged vermiform appendix with the uterus and adnexa macroscopically normal, and no signs of intraperitoneal metastasis or adnexal torsion. Laparotomic appendectomy followed. Histological examination revealed a mucinous cystadenoma of the vermiform appendix. This clinical entity of appendiceal mucocele should always be considered by gynaecologists as well as gastroenterologists in the differential diagnosis of patients presenting a right-sided adnexal mass on ultrasound in order to choose the best surgical approach.

A new approach to vulvar squamous cell carcinoma: two-year follow-up of a case report.

BACKGROUND: Vulvar carcinoma is relatively rare gynaecologic malignancy. The most prevalent vulvar cancer is squamous cell carcinoma. It is not uncommon for patients to delay seeking medical attention or for physicians to delay diagnosing the condition. This delay results in many cases being diagnosed in advanced stage. The sentinel lymph node "concept" is attractive in vulvar cancer because it has the potential to avoid a radical vulvectomy associated with uni- or bilateral inguinofemoral lymphadenectomy and, thus, to avoid the morbidity associated with formal groin dissection. CASE REPORT: A case of an 88-year-old woman with advanced local vulvar cancer is presented. A study of the inguinal-femoral lymph nodes was also conducted with intraoperative vital blue dye peritumoral injection and as the sentinel node was found to be negative for malignant metastasis, a radical vulvectomy without bilateral inguinofemoral lymphadenectomy and without additional treatment (chemotherapy and/or radiotherapy) was performed. Follow-up was performed at one, three, six, nine, 12, 18 and 24 months. No local recurrence or distant metastasis was found. CONCLUSION: The sentinel lymph node procedure allows a less aggressive treatment to be carried out in patients with invasive vulvar cancer thus reducing the complications and morbidity of treatment. Moreover, reducing the operative stress can change the overall survival and reduce the mortality linked to complications and postoperative stress.

Total thyroidectomy alone versus ipsilateral versus bilateral prophylactic central neck dissection in clinically node-negative differentiated thyroid carcinoma. A retrospective multicenter study.

BACKGROUND: Central neck dissection (CND) remains controversial in clinically node-negative differentiated thyroid carcinoma (DTC) patients. The aim of this multicenter retrospective study was to determine the rate of central neck metastases, the morbidity and the rate of recurrence in patients treated with total thyroidectomy (TT) alone or in combination with bilateral or ipsilateral CND. METHODS: The clinical records of 163 clinically node-negative consecutive DTC patients treated between January 2008 and December 2010 in three endocrine surgery referral units were retrospectively evaluated. The patients were divided into three groups: patients who had undergone TT alone (group A), TT with ipsilateral CND (group B), and TT with bilateral CND (group C). RESULTS: The respective incidences of transient hypoparathyroidism and unilateral recurrent nerve injury were 12.6% and 1% in group A, 23.3% and 3.3% in B, and 36.7% and 0% in C. Node metastases were observed in 8.7% in group A, 23.3% in B, and 63.3% in C. Locoregional recurrence was observed in 3.9% of patients in group A and in 0% in B and C. CONCLUSIONS: We found no statistically significant differences in the rates of locoregional recurrence between the three groups. Therefore, TT appears to be an adequate treatment for these patients; CND is associated with higher rates of transient hypoparathyroidism and cannot be considered the treatment of choice even if it could help for more appropriate selection of patients for RAI. Ipsilateral CND could be an interesting option considering the lower rate of hypocalcemia to be validated by further studies.

Minimally invasive approach for adrenal lesions: Systematic review of laparoscopic versus retroperitoneoscopic adrenalectomy and assessment of risk factors for complications.

In the last decades, minimally invasive transperitoneal laparoscopic adrenalectomy has become the standard of care for surgical resection of the adrenal gland tumors. Recently, however, adrenalectomy by a mininvasive retroperitoneal approach has reached increasingly popularity as alternative technique. Short hospitalization, lower postoperative pain and decrease of complications and a better cosmetic resolution are the main advantages of these innovative techniques. In order to determine the better surgical management of adrenal neoplasms, the Authors analyzed and compared the feasibility and the postoperative complications of minimally invasive adrenalectomy approaches. A systematic research of the English literature, including major meta-analysis articles, clinical randomized trials, retrospective studies and systematic reviews was performed, comparing laparoscopic transperitoneal adrenalectomy versus retroperitoneoscopic adrenalectomy. Many studies support that posterior retroperitoneal adrenalectomy is superior or at least comparable to laparoscopic transperitoneal adrenalectomy in operation time, pain score, blood loss, hospitalization, complications rates and return to normal activity. However, laparoscopic transperitoneal adrenalectomy is up to now a safe and standardized procedure with a shorter learning curve and a similar low morbidity rate, even for tumors larger than 6 cm. Nevertheless, further studies are needed to objectively evaluate these techniques, excluding selection bias and bias related to differences in surgeons' experiences with this approaches.

Pancreatic fistula following pancreatoduodenectomy. Evaluation of different surgical approaches in the management of pancreatic stump. Literature review.

Pancreatoduodenectomy is the gold standard operation for malignant and benign diseases of the pancreas and periampullary region. Even if improvements in intensive care management and surgical technique have dramatically reduced postoperative mortality after pancreatic surgery, morbidity remains high (30-50%), also in specialized pancreatic units. In order to reduce postoperative complications, particularly pancreatic fistula, different surgical techniques and their modifications have been proposed. In order to determine the better management of the pancreatic stump after pancreatoduodenectomy, the Authors analysed and compared derivative - pancreaticojejunal, pancreaticogastrostomy - vs no-derivative technique - pancreatic stump closure (duct ligation or mechanical suture, duct occlusion by fibrin glue or cyanoacrylate). A systematic research of the English literature, including major meta-analysis articles, clinical randomized trials, retrospective studies and systematic reviews was performed, analysing the risk factors and the incidence of short-medium term postoperative complications. Up to now, even if derivative procedures are preferred as gold standard the best method to deal a pancreatic stump is still controversial and remains matter of research. Pancreatic surgeons must have more than one technique for managing the pancreatic remnant.
