Large Neuroendocrine Neoplasms of the Duodenum: Description of Two Rare Subtypes and Technical Details on Surgical Treatment.

Background: Duodenal neuroendocrine tumors (NETs) are uncommon, accounting for less than 4% of all gastrointestinal neoplasms. Prognosis is related to tumoral staging and grading, as well as to the specific subtype. In this article, we retrospectively describe the clinical presentation and surgical treatment of two rare large duodenal NETs: a high-grade G3 NET and a Gangliocytic Paraganglioma (GP).

Papillary Thyroid Microcarcinoma: Differences between Lesions in Incidental and Nonincidental Settings-Considerations on These Clinical Entities and Personal Experience.

Papillary thyroid microcarcinoma (PTMC) represents 35-40% of all papillary cancers; it is defined as a nodule ≤ 10 mm at the time of histological diagnosis. The clinical significance of PTMC is still controversial, and it may be discovered in two settings: incidental PTMC (iPTMC), in which it is identified postoperatively upon histological examination of thyroid specimens following thyroid surgery for benign disease, and nonincidental PTMC (niPTMC), in which it is diagnosed before surgery. While iPTMC appears to be related to mild behavior and favorable clinical outcomes, niPTMC may exhibit markers of aggressiveness.

Management of low colorectal anastomotic leakage using negative pressure therapy with Transanal Minimally Invasive Surgery (TAMIS): description of a case and review of the literature.

Anastomotic leakage (AL) represents a major post-operative complication after low anterior resection (LAR) for rectal cancer. It is associated with increased morbidity, mortality, length of hospital stay and risk of permanent stoma. Herein we report the case of a 75-year-old male patient submitted to a minimally invasive LAR who developed an AL on the fifth post-operative day.

Small bowel adenocarcinoma: natural history of recurrence after surgical resection.

Small bowel adenocarcinomas (SBA) are a rare entity associated with a poor prognosis and an advanced stage of disease at diagnosis. Surgical resection is considered the gold standard of treatment for stage I-III, while stage IV disease approach is still debated. We present a case of a young woman affected by a duodenojejunal junction SBA treated with surgical resection and FOLFOX adjuvant chemotherapy.

Hybrid sequential treatment of a giant serous mesenteric cyst: description of a case and review of the literature.

Mesenteric cysts are uncommon benign abdominal tumors that may extend from the root of the mesenteric layers of the gastrointestinal tract into the retroperitoneum or the peritoneal cavity; they are usually asymptomatic and often represent an occasional finding. Definitive diagnosis is confirmed by the surgical intraoperative view and by histopathological examination. Surgical excision of the cyst is the treatment of choice.

Extended surgical resection for nonfunctioning duodenal neuroendocrine tumor.

Duodenal neuroendocrine tumors (NETs) account for <3% of all gastrointestinal NET. Most lesions are small-sized and are located in the first or second duodenal part. Tumoral grading, evaluated by Ki67 index, strongly influences patient's outcome.

Functional results after mesorectal excision for rectal cancer: comparative study among surgical approaches.

Background: We analyzed the evolution of genitourinary dysfunctions in patients undergoing surgical treatment for rectal cancer, and compared open surgery, laparoscopy, robotic and TaTME.

Methods: Functional outcomes were evaluate using standardized questionnaires, compiled at the start of treatment, after the end of Radiotherapy, at 1 and 6 months after surgery.

Results: In 72 patients 37.

Clinical competence in the surgery of rectal cancer: the Italian Consensus Conference.

Background And Aim: The literature continues to emphasize the advantages of treating patients in "high volume" units by "expert" surgeons, but there is no agreed definition of what is meant by either term. In September 2012, a Consensus Conference on Clinical Competence was organized in Rome as part of the meeting of the National Congress of Italian Surgery (I Congresso Nazionale della Chirurgia Italiana: Unità e valore della chirurgia italiana). The aims were to provide a definition of "expert surgeon" and "high-volume facility" in rectal cancer surgery and to assess their influence on patient outcome.

Total mesorectal excision: a comparison of oncological and functional outcomes between robotic and laparoscopic surgery for rectal cancer.

Background: Long-term data from the CLASICC study demonstrated the oncologic equivalence of laparoscopic and open rectal cancer surgery despite an increased circumferential resection margin involvement in the laparoscopic group in the initial report. Moreover, laparoscopic total mesorectal excision (TME) may be associated with increased rates of male sexual dysfunction compared to conventional open TME. Robotic surgery could potentially obtain better results than laparoscopy.

Robotic adrenalectomy: technical aspects, early results and learning curve.

Background: Adrenal surgery is undergoing continuous evolution, and robotic technology may extend indications for a minimally invasive approach to adrenalectomy.

Methods: Thirty robot-assisted unilateral transperitoneal adrenalectomy procedures have been performed at our Department over the last 5 years. The presence of bilateral lesions and vascular involvement were the only contra-indications for a minimally invasive approach.

Robotic splenectomy for mesothelial cyst: a case report.

Cystic lesions of the spleen represent a rare entity with an overall incidence of 0.5% among splenectomies. They can remain asymptomatic in 30% to 60% of patients or may cause symptoms for secondary compression of adjacent structures.

Fully robotic treatment of an epiphrenic diverticulum: report of a case.

Epiphrenic diverticula are rare protrusions of the distal esophagus attributed to esophageal motility disorders or obstructive diseases. In presence of a relevant symptomatology, surgery is mandatory. Although many reports confirm the feasibility of the laparoscopic transhiatal approach, the mobilization of the esophagus and the myotomy appear challenging.

Full robotic gastrectomy with extended (D2) lymphadenectomy for gastric cancer: surgical technique and preliminary results.

Background: Widespread diffusion of minimally-invasive surgery for gastric cancer treatment is limited by the complexity of performing an extended D2-lymphadenectomy. This surgical step can be facilitated by using robot-assisted surgery. The aim of this study is to describe our technique and short-term results of a consecutive series of full robotic gastrectomies with D2-lymphadenectomy for gastric cancer, using the da Vinci Surgical System.

Robotic right colon resection: evaluation of first 50 consecutive cases for malignant disease.

Background: Colorectal cancer is the fourth leading cause of death in the world. Minimally invasive surgery has been demonstrated to have the same oncological results as open surgery, with better clinical outcomes. Robotic assistance is an evolution of minimally invasive technique.

Impact of the latest TNM classification for gastric cancer: retrospective analysis on 94 D2 gastrectomies.

The aim of this study was to determine whether the latest edition of tumor-node-metastasis (TNM) classification provides reliable prognostic information. The fifth edition of TNM Classification of Malignant Tumors has introduced for gastric cancer the numeric count of involved lymph nodes whereas their topographic location was considered in earlier editions. For our study, data from 94 patients who underwent D2-gastrectomy were reviewed.
