• Intussusception is a rare cause of postoperative small bowel obstruction in adult and the treatment is still debated. • Bowel Intussusception should be kept in mind in a post operative patient who develops obstructive symptoms. • The time of diagnosis makes the difference between surgical treatment and others. • Abdominal CT have a good accuracy in diagnosis. • Surgery is necessary if peritoneal irritation is present. Otherwise, conservative treatment is considered. Postoperative intussusception is a rare cause of intestinal obstruction in adults. Intussusception refers to a condition in which a segment of the intestine invaginates into the lumen of an adjacent segment of the intestine. We report a case of postoperative jejunojejunal intussusception in a 42-year-old male following a laparoscopic low anterior resection for rectal cancer. In post-operative day (POD) 2 the patient showed intermittent bowel obstruction and fever. Diagnosis was established with abdominal computed tomography (CT) and enteroclysis, which led to a spontaneous reduction of the invagination. The incidence of intussusception in adults is rare condition. It represents less than 5% of all cases. In adults, transient asymptomatic enteric intussusception often resolves spontaneously without any treatment. When bowel obstruction is complete and persistent, surgery is need. Intussusception as cause of intestinal obstruction should be kept in mind in a post operative patient who develops obstructive symptoms. Early diagnosis makes the difference between surgical and others treatment. The pathogenesis and diagnosis of postoperative intussusception in the adult is discussed in the case report. The authors presented a rare cause of postoperative small bowel obstruction treated without surgery. The peculiarity of this case report is that the authors have successfully used, in an adult, conservative treatment with gastrografin, which is the treatment of choice used in children. The use of gastrografin was decisive and there were no recurrences in the follow up. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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: 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. [ABSTRACT FROM AUTHOR]

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.

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, nephronsparing surgery. More studies are needed to better analyze the relationship between NF1 gene mutation and SFT. [ABSTRACT FROM AUTHOR]

Primary smooth muscle tumors of the thyroid gland are extremely rare neoplasms. Due to their rarity, clinical case studies concerning management are lacking. According to a literature review, only 19 cases of primary thyroid leiomyosarcomas (TLs) have been reported. In the majority of patients, the prognosis is poor since adjuvant radiochemotherapy is ineffective on local recurrence and on long-term survival. In this study, we report the case of a 77-year-old male affected by a rapidly enlarging mass of the anterior neck, associated with bilateral lung metastases, and increasing dysphagia and dyspnea during the previous 6 months. A Tir4 neoplasm fine needle cytological diagnosis of the right thyroid lobe was reached and the patient underwent total thyroidectomy (TT). Definitive histological examination identified a TL. The patient succumbed 40 days later due to respiratory distress. A literature review was performed and TL differential diagnoses, management, including alternative treatment strategies, and adjuvant therapy were analyzed. TL is an aggressive rare mesenchymal malignant tumor. Although an improved multimodal approach is often necessary, TT and neck dissection represent the treatment of choice and are often the only possible therapy. Adjuvant radiochemotherapy appears to be ineffective and a high mortality rate is observed. TL remains a fatal tumor, and innovative and more effective therapeutic strategies to improve management and outcomes are required. [ABSTRACT FROM AUTHOR]

Background: The significance of nodal metastases, very common in papillary thyroid cancer, and the role of lymph node dissection in the neoplasm management, are still controversial. The impact of lymph node involvement on local recurrence and long-term survival remains subject of active research. With the aim to better analyze the predictive value of lymph node involvement on recurrence and survival, we investigated the clinico-pathological patterns of local relapse following total thyroidectomy associated with lymph node dissection, for clinical nodal metastases papillary thyroid cancer, in order to identify the preferred surgical treatment. Methods: Clinical records, between January 2000 and December 2006, of 69 patients undergoing total thyroidectomy associated with selective lymph node dissection for clinical nodal metastases papillary thyroid cancer, were retrospectively evaluated. Radioiodine ablation, followed by Thyroid Stimulating Hormone suppression therapy was recommended in every case. In patients with loco regional lymph nodal recurrence, a repeated lymph node dissection was carried out. The data were compared with those following total thyroidectomy not associated with lymph node dissection in 210 papillary thyroid cancer patients without lymph node involvement, at preoperative ultrasonography and intra operative inspection. Results: Incidence of permanent hypoparathyroidism (iPTH < 10 pg/ml) and permanent monolateral vocal fold paralysis were respectively 1.4 % (1/69) and 1.4% (1/69), similar to those reported after total thyroidectomy "alone". The rate of loco regional recurrence, with positive cervical lymph nodes, following 8 year follow-up, was 34.7% (24/69), higher than that reported in patients without nodal metastases (4.2%). A repeated lymph node dissection was carried out without significant complications. Conclusions: Nodal metastases are a predictor of local recurrence, and a higher rate of lymph node involvement is expected after therapeutic lymph node dissection associated with total thyroidectomy. The prognostic significance of nodal metastases on long-term survival remains unclear, and more prospective randomized trials are requested to better evaluate the benefits of different therapeutic approaches.

Abstract: INTRODUCTION: Median arcuate ligament (MAL) malposition is a rare cause of celiac axis compression syndrome (CACS) or Dunbar syndrome. PRESENTATION OF CASE: A 26-year-old female presented with severe postprandial epigastric pain, weight loss, heartburn and regurgitation unresponsive to medical therapy. CT angiography and duplex ultrasound demonstrated the MAL crossing anterior to the celiac artery (CA). Reconstructions demonstrated CA compression, while the superior mesenteric artery (SMA) was normal. The MAL was laparoscopically divided, releasing the celiac axis. A concomitant Nissen fundoplication was performed. At 3-months follow-up, the CT-scan demonstrated no evidence of CACS with complete symptom resolution. DISCUSSION: Dunbar's syndrome can be treated with endovascular surgery, laparoscopic MAL division or vascular surgery.Six anatomical and morphologic variations of aortic and esophageal hiatus are described. The result of the analysis of these anatomical data leads to the conclusion that hiatus hernia, Dunbar's syndrome and GERD have a common etiopathogenesis and physiopathology. CONCLUSION: Laparoscopic treatment is useful and feasible in centers with experience in majorlaparoscopic surgery with reduced invasiveness, better cosmetic effect and shorter postoperative course.
