RESUMEN

BACKGROUND: Ilio-inguinal lymphadenectomy for stage III melanoma and skin cancers still represents the best therapeutic option for a subset of patients, although the incidence of post-operative complications is dramatically high. Only a paucity of papers on robotic approach have been published, reporting experiences on isolated pelvic or inguinal lymphadenectomy, and no series on combined dissections have been described yet. We present the preliminary results achieved with combined robotic approach, with special emphasis on lymph nodal mapping, dissection technique and postoperative complications linked with the lymphatic system. METHODS: Between September 2019 and September 2021, 10 patients were submitted to robotic inguinal and iliac-obturator lymphadenectomy. RESULTS: Post-operative course was characterised by early mobilisation and minimal post-operative pain. Only one lymphoedema occurred and lymph nodal harvesting was more than satisfactory. CONCLUSIONS: Robotic surgery provides meticulous lymph nodal dissections, with promising functional and oncologic outcomes. Further series are advocated to confirm these preliminary results.

RESUMEN

BACKGROUND: Laparoscopic cholecystectomy is considered the gold standard for the treatment of gallbladder lithiasis; nevertheless, the incidence of bile duct injuries (BDI) is still high (0.3-0.8%) compared to open cholecystectomy (0.2%). In 1995, Strasberg introduced the "Critical View of Safety" (CVS) to reduce the risk of BDI. Despite its widespread use, the scientific evidence supporting this technique to prevent BDI is controversial. METHODS: Between March 2017 and March 2019, the data of patients submitted to laparoscopic cholecystectomy in 30 Italian surgical departments were collected on a national database. A survey was submitted to all members of Italian Digestive Pathology Society to obtain data on the preoperative workup, the surgical and postoperative management of patients and to judge, at the end of the procedure, if the isolation of the elements was performed according to the CVS. In the case of a declared critical view, iconographic documentation was obtained, finally reviewed by an external auditor. RESULTS: Data from 604 patients were analysed. The study population was divided into two groups according to the evidence (Group A; n = 11) or absence (Group B; N = 593) of BDI and perioperative bleeding. The non-use of CVS was found in 54.6% of procedures in the Group A, and 25.8% in the Group B, and evaluating the operator-related variables the execution of CVS was associated with a significantly lower incidence of BDI and intraoperative bleeding. CONCLUSIONS: The CVS confirmed to be the safest technique to recognize the elements of the Calot triangle and, if correctly performed, it significantly impacted on preventing intraoperative complications. Additional educational programs on the correct application of CVS in clinical practice would be desirable to avoid extreme conditions that may require additional procedures.

RESUMEN

Up to 25% of patients with acute diverticulitis develop complicated disease. Colocutaneous fistula with lower limb fasciitis secondary to complicated diverticulitis is a rare event. A 71-year-old woman with Class 3 obesity and Type 2 diabetes was admitted to the hospital because of left lower limb fasciitis associated with acute sigmoid diverticulitis complicated by covered perforation. The fasciitis was treated with multiple fasciotomies, antibiotics and hyperbaric oxygen therapy. The patient was readmitted 25 days after discharge because of the formation of a left leg colocutaneous fistula associated with an enterocolic fistula. Patient underwent sigmoid resection with primary anastomosis and ileal loop repair. Three-month follow-up showed fistula healing and absence of symptoms. Fasciitis secondary to acute diverticulitis is a rare clinical scenario. Although our therapeutic strategy was successful, the optimal treatment timing and surgical technique for fasciotomy and colon resection remain to be assessed.

RESUMEN

Introduction: In recent years, the introduction of targeted therapy and immunotherapy into clinical practice has radically changed the management of advanced melanoma. More recently, these treatments also became the standard of care in the adjuvant setting. However, high-risk resectable stage III melanoma (i.e. with clinically detected regional lymph node involvement and/or satellites/in transit metastases) still has a high risk of relapse, even after adjuvant treatment, suggesting that the activity of immunotherapy and targeted therapy may play a relevant role in a neoadjuvant setting.Area covered: In this review, we discuss the results of the main clinical trials conducted in the neoadjuvant setting for patients with resectable stage III and stage IV melanoma, with a focus on the hot topics and a look at the future perspectives of the field.Expert opinion: The long-term effects of immunotherapy and the high response rate of targeted therapy provided the strong rationale to start neoadjuvant clinical trials for patients with resectable stage III and oligometastatic stage IV melanoma. Neoadjuvant therapy may play an important role not only for its possible impact on overall survival, but also as a predictive biological marker to allow for a more accurate personalization of adjuvant treatments.

RESUMEN

BACKGROUND AND OBJECTIVES: The increasing use of arm totally implantable vascular access devices for breast cancer patients who require chemotherapy has led to a greater risk of complications and failures and, in particular, to upper extremity deep vein thrombosis. This study aims to investigate the outcomes of the arm peripherally inserted central catheter-PORT technique in breast cancer patients. METHODS: The peripherally inserted central catheter-PORT technique is an evolution of the standard arm-totally implantable vascular access device implant based on guided ultrasound venous access in the proximal third of the upper limb with subsequent placement of the reservoir at the middle third of the arm. A prospective study was conducted on 418 adult female breast cancer patients undergoing chemotherapy. The primary study outcome was peripherally inserted central catheter-PORT failure. RESULTS: Median follow-up was 215 days. Complications occurred in 29 patients (6.9%) and failure resulting in removal of the device in 11 patients (2.6%). The main complication we observed was upper extremity deep vein thrombosis, 10 (2.4%); all patients were rescued by anticoagulant treatment without peripherally inserted central catheter-PORT removal. The main reason for removal was reservoir pocket infection: 4 (0.9%) with an infection rate of 0.012 per 1000 catheter days. Cumulative 1-year risk of failure was 3.6% (95% confidence interval, 1.3%-7.1%). With regard to the patients' characteristics, body mass index <22.5 was the only significant risk for failure (p = 0.027). CONCLUSION: The peripherally inserted central catheter-PORT is a safe vascular device for chemotherapy delivery that achieves similar clinical results as traditional long-term vascular access devices (peripherally inserted central catheter and arm totally implantable vascular access device, in particular) in breast cancer patients.

RESUMEN

BACKGROUND: A positive correlation between calcium and magnesium serum levels is well known and depends upon various factors. This study aims at verifying the existence of this association in a retrospective series of patients who underwent thyroid surgery. METHODS: Two hundred and eighty-five consecutive patients (202 female, 83 male, mean age 57 years) who underwent at least total thyroidectomy (TT) and had a complete clinical and biochemical pre- and postoperative evaluation were included in the study. Patients were evaluated with regard to: sex, age, indications for surgery, operative time, number of accidentally removed parathyroids, extent and time of surgery, thyroiditis, final histology, pre- and postoperative levels of calcium, magnesium, vitamin D, and creatinine, presence of symptoms of hypocalcemia. Statistical analysis was performed using the R software. RESULTS: In the postoperative period, biochemical hypocalcemia (<8.5 mg/dL) was observed in 126 patients (44%) and severe hypocalcemia (<7.5 mg/dL, a level indicating the need for longer hospitalization) was seen in 40 (14%). When analyzing patients with and without postoperative hypocalcemia, the factors affecting postoperative biochemical hypocalcemia were: older age (P=0.019), longer operative time (P=0.039), and a highly significant correlation between postoperative calcium and magnesium levels (r=0.432; P<0.001). CONCLUSIONS: The only factor among the ones we analyzed in this retrospective study that would appear to be linked to the onset of clinically relevant hypocalcemia is low magnesium levels in the postoperative period. A prospective randomized study with a group of patients undergoing magnesium replacement in the postoperative period can clarify the possible role of magnesium repletion on hypocalcemia.

RESUMEN

BACKGROUND: This study investigates the incidence of post-operative complications and risk factors of sentinel lymph node biopsy (SLNB) in melanoma patients. METHODS: A retrospective cohort study was conducted at a single cancer institution on 408 consecutive SLNBs. RESULTS: Fifty-five post-operative complications occurred in 39 (9.5%) patients and included: wound infection in 24 (5.9%), seroma and lymphorrhea in 15 (3.7%), wound dehiscence in seven (1.7%), lymphocele in six (1.5%) and others in three (0.7%). Univariate analysis failed to identify possible risk factors (i.e. gender, age, lymph node region, number of excised lymph nodes, Breslow index, pT levels, comorbidities, length of surgery and hospital stay). Metastatic sentinel nodes occurred in four of 135 (3%) patients with thin melanoma (Breslow <1 mm) and in 68 of 262 (25.9%) patients with Breslow >1 mm. CONCLUSION: For patients with thin melanoma in whom the incidence of lymph node metastasis is low, the reported post-operative morbidity of almost 10% of SLNB highlights the need for careful patient selection.

RESUMEN

INTRODUCTION: Eccrine porocarcinoma (EPC) is a slow-growing carcinoma arising from the eccrine sweat glands. Based on its clinical presentation it can be confused with malignant and benign skin lesions, both. Histological examination is essential to formulate a correct diagnosis. Surgical excision with clear margins is the standard therapeutic approach while the role of sentinel lymph node biopsy (SNLB) remains controversial. CASE PRESENTATION: The Authors report two cases of EPC of the lower limbs occurred in two women. Patients were treated by wide surgical excision of the lesion and SNLB. 6 months follow-up was disease free for both patients. CONCLUSION: Although a rare cutaneous tumor, EPC has to be taken into account in the differential diagnosis of malignant skin lesions because of its possible loco-regional aggressiveness and related morbidity. Among the available treatment options, surgical excision is considered the standard approach whereas the role of SNLB is controversial although the Authors discuss a possible usefulness for staging and diagnosis.

RESUMEN

BACKGROUND: The aim of this study was to evaluate a possible relationship between lunar cycles and haemorrhagic complication rate in surgery. MATERIALS AND METHODS: The possible relationship between moon phases and surgical outcome was tested by evaluating the haemorrhagic complication rate for 18,760 patients who underwent surgery between January 2001 and December 2008 at the National Institute for Cancer Research in Genoa. A total of 103 lunar phases were considered using Chi-square (χ2) test analysis, and patients were allocated a surgery date. RESULTS: One hundred and sixty-seven haemorrhagic complications were observed. Three hundred and nine new moon phase days were analysed and 12 incidences of complications detected, with a 3.9% complication rate per day. In the waxing moon phase, 1184.5 d were analysed with 68 incidences of complications at a daily rate of 5.7%. In the full moon phase there was a 4.9% complication rate per day (15 incidences in 309 d), whereas in the waning moon phase, the 6% percentage rate per day resulted from 72 incidences in 1184.5 d. CONCLUSIONS: No statistically significant correlations were found between moon cycles and postoperative haemorrhagic complications (p = .50).

RESUMEN

AIM: The feasibility of videoscopic inguinal-iliac-obturator lymphadenectomy (VIIOL) was assessed in 20 patients with melanoma and compared with a retrospective sample of 24 patients undergoing standard 'open' technique (IIOL). RESULTS: No postoperative death occurred; the mean operative time was lower in the IIOL series (190 min vs. 302 min) but the quality of life was greatly improved in the VIIOL group thanks to earlier bladder catheter removal, no nasogastric suction, less pain, earlier mobilization, lower in-hospital stay, and earlier resumption of daily activities (27.6 vs. 83.2 days, p<0.001). Six out of 20 patients in the IIOL series had wound complications (30%) as compared to one in the VIIOL series (4%) (p=0.035). CONCLUSION: Staging and therapeutic efficacy of VIIOL were similar to the standard technique; the longer operative time of VIIOL was greatly compensated by less pain, lower wound complication rate, and earlier discharge from hospital and recovery of daily activities.

RESUMEN

BACKGROUND AND OBJECTIVES: The increasing use of peripherally inserted central venous catheters (PICCs) for chemotherapy has led to the observation of an elevated risk of complications and failures. This study investigates PICC failures in cancer patients. METHODS: A prospective study was conducted at a single cancer institution on 291 PICC placement for chemotherapy. The primary study outcome was PICC failure. RESULTS: Median follow-up was 119 days. PICC complications occurred in 72 patients (24.7%) and failures with removal in 44 (15.1%). Reasons for failures were upper extremity deep venous thrombosis (UEDVT) 12 (4.1%), central line associate bloodstream infection (CLABSI) 5 (1.7%) with an infection rate of 0.95 per 1,000 catheter days, exit site infection 9 (3.1%) with a rate of 1.46 per 1,000 catheter days, catheter dislodgment 11 (3.8%), and occlusion 7 (2.4%). Statistically significant risk factors were previous DVT (HR 2.95, 95%CI 1.33-6.53), reason for PICC implant (HR 3.65, 95%CI 1.12-10.34) and 5-fluorouracil, oxaliplatin and bevacizumab based chemotherapy (HR 3.11, 95%CI 1.17-8.26). CONCLUSIONS: PICC is a safe venous device for chemotherapy delivery. Nevertheless, a 15% rate of failure has to be taken in account when planning PICC insertion for chemotherapy purposes. J. Surg.

RESUMEN

Parathyroid surgery underwent significant innovations in the past 20 years, after both the improvement of the imaging techniques used to localize abnormal parathyroids (ultrasonography and MIBI scintiscan) and the possibility of the intraoperative PTH assay. These two tools, in experienced hands, can correctly differentiate uniglandular (more than 85% of the cases of primary hyperparathyroidism) from multiglandular disease. These technological improvements led to the possibility of limiting the surgical exploration to the single parathyroid responsible for the hyperparathyroidism in the majority of cases, avoiding unnecessary bilateral exploration that might increase both the morbidity of the surgery and its global costs. Furthermore, from a technical point of view, the philosophy of a minimally invasive surgery has also been applied to parathyroidectomy and several techniques have been described which are commonly considered minimally invasive. In this paper, the authors want to summarize their indications to perform a focused parathyroidectomy vs. a more traditional bilateral exploration, their definition of a minimally invasive parathyroidectomy and finally, it is given an overview of the techniques currently used for a parathyroidectomy.

RESUMEN

THE CERVICAL BRANCHES OF THE VAGUS NERVE THAT ARE PERTINENT TO ENDOCRINE SURGERY ARE THE SUPERIOR AND THE INFERIOR LARYNGEAL NERVES: their anatomical course in the neck places them at risk during thyroid surgery. The external branch of the superior laryngeal nerve (EB) is at risk during thyroid surgery because of its close anatomical relationship with the superior thyroid vessels and the superior thyroid pole region. The rate of EB injury (which leads to the paralysis of the cricothyroid muscle) varies from 0 to 58%. The identification of the EB during surgery helps avoiding both an accidental transection and an excessive stretching. When the nerve is not identified, the ligation of superior thyroid artery branches close to the thyroid gland is suggested, as well as the abstention from an indiscriminate use of energy-based devices that might damage it. The inferior laryngeal nerve (RLN) runs in the tracheoesophageal groove toward the larynx, close to the posterior aspect of the thyroid. It is the main motor nerve of the intrinsic laryngeal muscles, and also provides sensory innervation to the larynx. Its injury finally causes the paralysis of the omolateral vocal cord and various sensory alterations: the symptoms range from mild to severe hoarseness, to acute airway obstruction, and swallowing impairment. Permanent lesions of the RNL occur from 0.3 to 7% of cases, according to different factors. The surgeon must be aware of the possible anatomical variations of the nerve, which should be actively searched for and identified. Visual control and gentle dissection of RLN are imperative. The use of intraoperative nerve monitoring has been safely applied but, at the moment, its impact in the incidence of RLN injuries has not been clarified. In conclusion, despite a thorough surgical technique and the use of intraoperative neuromonitoring, the incidence of neurological complications after thyroid surgery cannot be suppressed, but should be maintained in a low range.

RESUMEN

From January 2003 to March 2010, a prospective study was undertaken at the National Cancer Research Institute of Genoa in 15 patients with melanoma who had local recurrence (LR) or a few (≤ 3) in-transit metastases and clinically-negative regional lymph nodes with the aim of defining: i) the feasibility of sentinel node re-staging (r-sN) of the regional nodal basin; ii) the prognostic value of sentinel node status, and iii) the potential benefit in terms of disease-free survival and overall survival in patients with an histologically-positive sentinel node undergoing therapeutic regional lymph node dissection. Preoperative lymphoscintigraphy was performed to identify the r-sN: the radiotracer was intra-dermally injected around the LR or in-transit metastasis. Moreover, 10 min prior to the operative procedure, 0.5 ml intradermal injection of Patent-Blue-V dye was given around each LR or in-transit metastasis site, so that r-sN identification was achieved by both visualization of the nodal blue dye staining and the information supplied by gamma-detection probe. At least one sentinel node was intra-operatively identified in each patient, and a tumor-positive r-sN was required in four out of fifteen patients. The interval between the diagnosis of primary melanoma and the onset of recurrence was longer, although not significantly, in patients with tumor-negative r-sN, a compared to tumor-positive r-sN (49 ± 47 months vs. 25 ± 19 months, p=0.342). There was a trend toward an improved 1-, 3-, and 5-year disease-free survival and overall survival in patients with tumor-negative r-sN a compared to tumor-positive r-sN. Hence, the r-sN proved to be a feasible and accurate staging procedure even in patients with a few localizations of LR or in-transit metastases (≤ 3). r-sN identified those with a more favorable prognosis, supporting an aggressive therapeutic approach in the natural history of their disease; moreover, an unnecessary regional lymph node dissection was safely avoided in 11 out of 15 73.3% patients because they had a tumor-negative r-sN.

RESUMEN

BACKGROUND AND OBJECTIVES: Electrochemotherapy (ECT) is technique for local control of skin metastasis. This study is primarily aimed at assessing the clinical activity of ECT in a prospective cohort of patients, and evaluating the association between primary tumor histology, number of metastatic lesions and size of tumor deposits and objective response rate. METHODS AND RESULTS: Thirty-nine patients with skin metastases from melanoma and other tumors underwent intravenous bleomycin ECT with palliative intent. No serious adverse events (SAE) or CTC grade 3 or 4 were observed. Overall response rate (ORR) was 66.6%. Response rate significantly correlated at univariate analysis both with the number (< or >10) and the size (< or >2 cm) of metastases. No relationship was observed for the histology of primary tumor. At multivariate analysis the size of the nodules under 2 cm was associated with a positive response and the correlation was statistically significant. CONCLUSIONS: ORR was 66.6% and all patients obtained a subjective clinical benefit from the treatment with minimal side effects. The most suitable patients were the ones with nodules <2 cm.

RESUMEN

Patient-related, tumor-related, and sentinel node (SN)-related factors have been identified with the aim of predicting non-SN status in patients with SN micrometastases. According to our previous experience, primary tumor size (p=0.005) and the presence of lymphovascular invasion (LVI) (p=0.000) significantly predicted non-SN status in patients with SN micrometastasis; moreover, non-SN metastases were never detected in patients with pT1a-1b, G1, and no LVI. A prospective assessment was undertaken in a validation set of 126 patients to confirm these findings. Univariate analysis indicated that primary tumor size (p=0.05), Scarff-Bloom-Richardson (SBR) grade (p=0.008), LVI (p=0.001), and the number of mitoses/mm(2) (p=0.01) were significant predictors of non-SN status. By logistic regression analysis, tumor size (p=0.03), LVI (p=0.001), grade (p=0.003) and the number of mitoses/mm(2) (p=0.01) were the only variables remaining in the model. Three subsets of patients were identified: i) 18.3% of patients (pT1, G1, and no LVI) had tumor-negative non-SN (no risk group); ii) 37.3% of patients (number of mitoses/mm(2) <10, SBR grade II-III) had a rate of tumor-positive non-SN <15% (intermediate risk); iii) 44.4% of patients had a mean rate of non-SN involvement of 46% (high risk). By these parameters, more than 50% of patients could be selectively spared unnecessary axillary lymph node dissection without staging or therapeutic benefit, especially in patients with well-differentiated pT1 tumors without LVI.

RESUMEN

BACKGROUND: Open colorectal cancer (CRC) surgery induces severe and prolonged postoperative pain. The optimal method of postoperative analgesia in CRC surgery has not been established. We evaluated the efficacy of preperitoneal continuous wound infusion (CWI) of ropivacaine for postoperative analgesia after open CRC surgery in a multicenter randomized controlled trial. METHODS: Candidates for open CRC surgery randomly received preperitoneal CWI analgesia or continuous epidural infusion (CEI) analgesia with ropivacaine 0.2% 10 mL/h for 48 hours after surgery. Fifty-three patients were allocated to each group. All patients received patient-controlled IV morphine analgesia. RESULTS: Over the 72-hour period after the end of surgery, CWI analgesia was not inferior to CEI analgesia. The difference of the mean visual analog scale score between CEI and CWI patients was 1.89 (97.5% confidence interval = -0.42, 4.19) at rest and 2.76 (97.5% confidence interval = -2.28, 7.80) after coughing. Secondary end points, morphine consumption and rescue analgesia, did not differ between groups. Time to first flatus was 3.06 ± 0.77 days in the CWI group and 3.61 ± 1.41 days in the CEI group (P = 0.002). Time to first stool was shorter in the CWI than the CEI group (4.49 ± 0.99 vs 5.29 ± 1.62 days; P = 0.001). Mean time to hospital discharge was shorter in the CWI group than in the CEI group (7.4 ± 0.41 and 8.0 ± 0.38 days, respectively). More patients in the CWI group reported excellent quality of postoperative pain control (45.3% vs 7.6%). Quality of night sleep was better with CWI analgesia, particularly at the postoperative 72-hour evaluation (P = 0.009). Postoperative nausea and vomiting was significantly less frequent with CWI analgesia at 24 hours (P = 0.02), 48 hours (P = 0.01), and 72 hours (P = 0.007) after surgery evaluations. CONCLUSIONS: Preperitoneal CWI analgesia with ropivacaine 0.2% continuous infusion at 10 mL/h during 48 hours after open CRC surgery provided effective postoperative pain relief not inferior to CEI analgesia.

RESUMEN

BACKGROUND: Since 2004 in the Department of Oncological Integrated Surgery at the National Institute for Cancer Research of Genoa, we have applied different techniques of reduction mammaplasty for a subgroup of 26 patients with medium- to large-sized and ptotic breasts who are candidates for conservative surgery. METHODS: In this series of patients, the choice between different techniques of breast reduction (superior or inferior pedicled or with free areola-nipple graft) depended only on cancer position. The chosen technique minimized reshaping and displacement of residual glandular flaps. In September 2009, the radiotherapists at the Institute began to apply intraoperative radiotherapy (IORT) to early breast cancer, and at the time of this report, more than 200 patients have been treated. RESULTS: This report describes two cases of reduction mammaplasty associated with this new and easily performed radiotherapy option (IORT) and discusses its advantages and cautions. CONCLUSIONS: Close collaboration between surgical oncologist, plastic surgeon, and radiotherapist is essential before and during surgery to obtain adequate tumor resection and good aesthetic results and to minimize postoperative complications.

RESUMEN

Cancer patients with complicated infections following abdominal surgery represent one of the worst clinical scenarios that is useful for testing the efficacy of empirical antimicrobial therapy. No study so far has evaluated the performance of tigecycline (TIG) when administered as empirical first-line treatment in a homogeneous population of surgical cancer patients with a febrile episode. An observational review of the data records of 24 sequential patients receiving TIG for a febrile episode following a major abdominal procedure in a single cancer institute was performed. Large bowel surgery represented 68% of all procedures, followed by gastric surgery (16%) and urinary-gynaecologic-biliary surgery (16%). Complications following surgery were observed in 68% of febrile episodes, with peritonitis and sepsis accounting for 59% and 24% of complications, respectively. Eight patients needed repeat surgery for source control. The mean duration of TIG treatment was 8 days. Causative pathogens were detected in 16 episodes (64%), and a total of 44 microorganisms were recovered (29% Escherichia coli, 9% Enterococcus faecalis and 9% coagulase-negative staphylococci). TIG was effective in 12 episodes (48%). The success rate was 67% when infectious episodes sustained by intrinsically resistant bacteria and fungi were excluded. Treatment failure was associated with the presence of complications and with microbiologically documented infection. TIG may be useful as a first-line treatment option in cancer patients requiring antibiotic treatment following surgery when complications are not present or suspected on clinical grounds and when local microbial epidemiology shows a low incidence of primary resistant bacteria.
