BACKGROUND: Near-total splenectomy (NTS) represents an innovative and effective surgery technique for spleen disease, reducing the risk of severe infections and thromboembolic events after total splenectomy. The authors reported a laparoscopic near-total splenectomy (LNTS) surgical experience following the optimal results of the open approach, describing a standardized and effective minimally invasive technique with the purpose of preserving a minimal residual spleen. MATERIAL AND METHODS: From November 2006 to September 2016, 15 patients with splenic and hematologic disease underwent LNTS, according to a laparoscopic procedure developed by the authors. The end criterion was to conserve a remanent spleen of 10-15 cm3 in size. RESULTS: Patient age ranged between 18 and 59 years. Mean operative time was 70 ± 20 min. Mean hospital stay was 3.46 (range 3-7) days. One complication occurred during the surgery for a lesion of the inferior polar artery with need of a total splenectomy. No conversion to open surgery was necessary. CONCLUSIONS: LNTS is a safe and effective technique for the management of splenic and hematologic disease with a low intra- and post-operative complication rate, and it can minimize the late sequelae of secondary splenectomy. However, it requires further studies with more cases to evaluate its role.

Background Choledocholithiasis occurs in 10–15% of patients with cholecystolithiasis. Despite the existence of many therapeutic options for the treatment of cholecystocholedocholithiasis, a sequential treatment in which pre-operative ERCP is combined with intraoperative cholangiography (IOC) and laparoscopic cholecystectomy (LC), is the most commonly accepted strategy. However, use of IOC in the "splitting treatment" of cholecystocholedocholithiasis is controversial. The aim of the present study is to investigate the utility of IOC in detecting residual stones in patients undergoing LC in the sequential treatment of common biliary duct or gallbladder stones. Methods Patients were recruited retrospectively among those who underwent IOC during LC, performed as second stage in the sequential treatment for cholecystocholedocholithiasis between 2010 and 2016. Demographic and clinical data were obtained from CPT codes at Ospedale Monaldi A.O.R.N dei Colli Naples, Italy. Data obtained from all pre-operative ERCP analyses were recorded, including cholangiogram findings and performance of sphincterotomy. Statistical analysis was carried out using the IBM SPSS Statistic 19.0 software package. Results Between January 2010 and December 2016 575 patients (343 males, 242 females) underwent IOC during LC for symptomatic cholecystitis due to cholelithiasis. Among patients accrued for the study, 143 underwent preoperative ERCP for suspicion of common biliary duct stones. At the time of pre-operative ERCP, 123 were found to have common biliary duct stones while 20 (15%) presented negative ERCP. Complete removal of stones was accomplished in 119 patients. Among these patients, 13 had residual common biliary duct stones diagnosed by IOC (11%). Two patients underwent laparoscopic bile duct revision and, last, two patients were referred for ERCP at a later point. It is of note that all patients who presented residual stones by IOC had undergone pre-operative sphincterotomy. Conclusion This study demonstrates that IOC is particularly effective in detecting residual stones in patients undergoing LC in sequential treatment of common biliary duct and/or gallbladder stones, and may be used on a routine basis in the sequential treatment of cholecystocholedocholithiasis.

Although intracorporeal anastomosis has been demonstrated to be safe and effective after right colectomy, limited data are available about its efficacy after left colectomy for colon cancer located in splenic flexure. A multi-institutional audit was designed, including 92 patients who underwent laparoscopic left colectomy with intracorporeal anastomosis (IA) compared with 89 matched patients who underwent a laparoscopic left colectomy with extracorporeal anastomosis (EA). There was no significant difference in terms of age, sex, BMI, and ASA score between the two groups. Post-surgical history and stage of disease according to AJCC/UICC TNM were also similar. IA and EA groups demonstrated similar oncologic radicality in terms of the number of lymph nodes harvested (18.5 ± 9 vs. 17.5 ± 8.4; p = 0.48). Recovery after surgery was also better in patients who underwent IA, as confirmed by the shorter time to flatus in the IA group (2.6 ± 1.1 days vs. 3.4 ± 1.2 days; p < 0.001) and higher post-operative pain expressed in the mean VAS Scale in the EA group (1.7 ± 2.1 vs. 3.5 ± 1.6; p < 0.001). Laparoscopic left colectomy with intracorporeal anastomosis was associated with a lower rate of post-operative complications (OR 6.7, 95% CI 2.2–20; p = 0.001). However, when stratifying according to Clavien classification, the difference was consistently confirmed for less severe (class I and II) complications (OR 7.6, 95% CI 2.5–23, p = 0.001) but not for class III, IV, and V complications (OR 1.8, 95% CI 0.1–16.9; p = 0.59). Our results were consistent to hypothesize that a complete laparoscopic approach could be considered a safe method to perform laparoscopic left colectomy with the advantage of a guaranteed faster recovery after surgery. Further randomized clinical trials are needed to obtain a more definitive conclusion.

Highlights • We report on the application of Irreversible electroporation (IRE) on locally advanced pancreatic cancer (LAPC). • We report on a minimally invasive surgical approach supported by laparoscopic ultrasound. • We report on a novel technique the benefits of IRE with the advantages of laparoscopic surgery. • In medical literature is in our knowledge the first experience., Introduction Pancreatic cancer is one of the most lethal cancers worldwide, with 5-years survival rate as low as 6%. The majority of pancreatic cancer patients present locally advanced or metastatic disease at diagnosis. Typically, patients affected by locally advanced pancreatic cancer (LAPC) do not undergo radical surgery but are treated with focal ablative therapies. However, a high rate of morbidity due to the heat sink effect has limited the application of ablative techniques on a routine basis in LAPC patients. Irreversible electroporation (IRE) has proved to be a new method of LAPC ablation. Presentation of the case A 69-year-old woman affected by LAPC with good response to systemic chemotherapy with FOLFIRINOX and residual 35 mm mass in the neck of the pancreas underwent to IRE through a minimally invasive surgical approach under laparoscopic ultrasound guide. The post-operative course was uneventful and the patient was discharged after 5 days. Six months after surgery she had no evidence of distant or recurrent disease. Discussion IRE has previously shown promising results in the treatment of LAPC, with relatively acceptable morbidity rates and improvement of survival. We report on the application of IRE through a minimally invasive surgical approach supported by laparoscopic ultrasound. Conclusion In conclusion, we propose a novel technical approach that combines the benefits of IRE on the treatment of patients affected by LAPC with the advantages of laparoscopic surgery.

Background The gold standard approach for surgical treatment of benign and malignant adrenal lesion is considered the laparoscopic one, due to a lot of advantages compared to open approach. The rapid propagation of this surgical technique is due to the diffusion of haemostatic devices in laparoscopic adrenal surgery. The principal aim of this study is to analyze the outcome of LA using each energy modality, evaluating the eventual superiority of an instrument over the others. Methods A retrospective study, involving 75 consecutive patients submitted to LA by transperitoneal lateral approach from January 2013 to June 2017, was performed. Age less than 70 years old, adrenal adenomas less than 8 cm in diameter, incidentalomas 0.05). Significant statistical difference are detectable in operation time and intraoperative blood losses. Thunderbeat, compared respectively with Ligasure and Harmonic Scalpel, is the fastest device (p

The most appropriate surgical management of "follicular neoplasm/suspicious for follicular neoplasm" lesions (FN), considering their low definitive malignancy rate and the limited predictive power of preoperative clinic-diagnostic factors, is still controversial. On behalf of the Italian Association of Endocrine Surgery Units (U.E.C. CLUB), we collected and analyzed the experience of 26 endocrine centers by computerized questionnaire. 1379 patients, surgically treated after a FN diagnosis from January 2012 and December 2103, were evaluated. Histological features, surgical complications, and medium-term outcomes were reported. Total thyroidectomy (TT) was performed in 1055/1379 patients (76.5 %), while hemithyroidectomy (HT) was carried out in 324/1379 cases (23.5 %). Malignancy rate was higher in TT than in HT groups (36.4 vs. 26.2 %), whereas the rates of transient and definitive hypoparathyroidism following TT were higher than after HT. Consensual thyroiditis (16.8 vs. 9.9 %) and patient age (50.9 vs. 47.9 %) also differed between groups. A cytological FN diagnosis was associated to a not negligible malignancy rate (469/1379 patients; 34 %), that was higher in TT than in HT groups. However, a lower morbidity rate was observed in HT, which should be considered the standard of care in solitary lesions in absence of specific risk factors. Malignancy could not be preoperatively assessed and clinical decision-making is still controversial. Further efforts should be spent to more accurately preoperatively classify FN thyroid nodules.

Background Lymph nodal involvement is very common in differentiated thyroid cancer, and in addition, cervical lymph node micrometastases are observed in up to 80 % of papillary thyroid cancers. During the last decades, the role of routine central lymph node dissection (RCLD) in the treatment of papillary thyroid cancer (PTC) has been an object of research, and it is now still controversial. Nevertheless, many scientific societies and referral authors have definitely stated that even if in expert hands, RCLD is not associated to higher morbidity; it should be indicated only in selected cases. Main body In order to better analyze the current role of prophylactic neck dissection in the surgical treatment of papillary thyroid cancers, an analysis of the most recent literature data was performed. Prophylactic or therapeutic lymph node dissection, selective, lateral or central lymph node dissection, modified radical neck dissection, and papillary thyroid cancer were used by the authors as keywords performing a PubMed database research. Literature reviews, PTCs large clinical series and the most recent guidelines of different referral endocrine societies, inhering neck dissection for papillary thyroid cancers, were also specifically evaluated. A higher PTC incidence was nowadays reported in differentiated thyroid cancer (DTC) clinical series. In addition, ultrasound guided fine-needle aspiration citology allowed a more precocious diagnosis in the early phases of disease. The role of prophylactic neck dissection in papillary thyroid cancer management remains controversial especially regarding indications, approach, and surgical extension. Even if morbidity rates seem to be similar to those reported after total thyroidectomy alone, RCLD impact on local recurrence and long-term survival is still a matter of research. Nevertheless, only a selective use in high-risk cases is supported by more and more scientific data. Conclusions In the last years, higher papillary thyroid cancer incidence and more precocious diagnoses were worldwide reported. Among endocrine and neck surgeons, there is agreement about indications to prophylactic treatment of node-negative “high-risk” patients. A recent trend toward RCLD avoiding radioactive treatment is still debated, but nevertheless, prophylactic dissections in low-risk cases should be avoided. Prospective randomized trials are needed to evaluate the benefits of different approaches and allow to drawn definitive conclusions.

In the last years, especially thanks to a large diffusion of ultrasound-guided FNBs, a surprising increased incidence of differentiated thyroid cancer (DTC), "small" tumors and microcarcinomas have been reported in the international series. This led endocrinologists and surgeons to search for "tailored" and "less aggressive" therapeutic protocols avoiding risky morbidity and useless "overtreatment". Considering the most recent guidelines of referral endocrine societies, we analyzed the role of routine or so-called prophylactic central compartment lymph node dissection (RCLD), also considering its benefits and risks. Literature data showed that the debate is still open and the surgeons are divided between proponents and opponents of its use. Even if lymph node metastases are commonly observed, and in up to 90% of DTC cases micrometastases are reported, the impact of lymphatic involvement on long-term survival is subject to intensive research and the best indications of lymph node dissection are still controversial. Identification of prognostic factors for central compartment metastases could assist surgeons in determining whether to perform RLCD. Considering available evidence, a general agreement to definitely reserve RCLD to "high-risk" cases was observed. More clinical researches, in order to identify risk factors of meaningful predictive power and prospective long-term randomized trials, should be useful to validate this selective approach.

Introduction: Anaplastic thyroid carcinoma (ATC) is a killer tumor, characterized by local invasiveness, risk of recurrence and very poor prognosis. Due to its rarity, clinical case studies concerning management are lacking. Methods: We retrospectively reviewed a multinstitutional clinical series of 114 consecutive patients treated between 1996 and 2012 for ATC. The outcomes of a combined treatment were analyzed considering the impact of surgery and radiotherapy on survival. Results: Patients were divided in groups A and B considering tumor size (tumor lesser and larger than 5 cm). Surgery was carried out in 71 patients, radiotherapy in 89 patients. Tracheostomy and endoprothesis were used respectively in 48.7% and in 25.6% of patients. The mean survival was 5.35 (±3.2) months with no significant difference in group A vs group B. A better survival was observed in both groups of patients undergone a surgical treatment compared to no treated patients (p ¼ 0.001 and p ¼ 0.0001) or to patients undergone radiotherapy alone (p ¼ 0.047 and p ¼ 0.0001). Combination of surgery and radiotherapy significantly improved outcome (p ¼ 0.017). Discussion: Despite disappointing results from single therapeutic approach, multimodal strategy has progressively become the treatment of choice in ATC, with surgery being the cornerstone of the management. Conclusion: Although dismal prognosis, the combined treatment might significantly improves locoregional disease control, achieving acceptable survival in selected patients and adequate palliation of the symptoms. © 2014 Published by Elsevier Ltd on behalf of Surgical Associates Ltd.

Background Pancreatic fistula (PF) after pancreatoduodenectomy (PD) represents the major source of morbidity. Derivative procedures are preferred by pancreatic surgeons, but the optimal management of remnant pancreatic stump remains controversial.Aims The purpose of this retrospective study is to evaluate the efficacy and safety of pancreatic stump closure in selected elderly patients (> 65 years).Methods Clinical data of 44 PD undergone mechanical closure of the pancreatic stump performed between 2001 and 2014 in two department of general and oncologic surgery were retrospectively collected. Considering the age, patients were divided into two groups: 21 patients of less than 65 years (Group A) and 23 patients of more than 65 years (Group B).Results A soft pancreatic parenchyma with a not-dilated duct (diameter < 3 mm) was reported in all the 44 patients. A grade-A PF, which did not required further treatments, developed in 20 cases (45.4%; 13 in group A and 7 in group B; p < 0.05), grade-B in 5 patients (11.4%; 3 in group A and 2 in group B; statistically not significant) and a grade-C PF was observed only in one patient (2.2%; 1 in group A and 0 in group B).Discussion In selected "high risk'' elderly patients (> 65 years) with soft pancreatic texture, the closure of the pancreatic stump can be a useful tool in the surgical armamentarium with the aim to reduce the incidence of age-related complications.Conclusions Prospective randomized controlled trial to better evaluate PF risk factors is needed.

Solitary fibrous tumor (SFT) is a rare spindle cell neoplasm, usually occurring in the pleura. Pararenal SFT, mimicking an adrenal gland or renal tumor, as here described, is extremely rare. We report a case of a right suprarenal SFT, incidentally discovered by abdominal ultrasound in a 54-year-old woman carrying a point neurofibromatosis 1 (NF1) gene mutation. Preoperative diagnostic work-up was ineffective in evaluating its origin, and an open radical right nephrectomy was therefore undertaken. Immunohistochemical assay showed a positivity for CD34, CD99 and Bcl-2, so suggesting a diagnosis of SFT. According to our knowledge, the association between this type of tumor and NF1 gene mutation has never been described. In cases of pararenal tumors, a more detailed preoperative diagnosis could be useful to better plan the extension of resection, allowing, in selected cases, nephron-sparing surgery. More studies are needed to better analyze the relationship between NF1 gene mutation and SFT.
