Dimitrios Mantas; Petros Charalampoudis; Nikolaos Nikiteas

INTRODUCTION The risk of periampullary neoplasia in patients with familial adenomatous polyposis (FAP) is significantly increased compared to the general population. PRESENTATION OF CASE We herein report the case of a 47-year-old woman with classic familial adenomatous polyposis with a history of total proctocolectomy for FAP who presented with an ulcerous ampullary lesion 8 years after primary colorectal surgery. Interestingly, the patient had not enrolled to optimal postoperative upper endoscopy follow-up. The patient underwent a Whipple procedure. Histology demonstrated a T2N0 ampullary adenocarcinoma. DISCUSSION Periampullary disease in patients with familial adenomatous polyposis occurs increasingly, especially in the subset of patients without proper endoscopic follow-up. Current recommendations concerning upper endoscopy and appropriate management are herein discussed; the importance of optimal postoperative endoscopy after total proctocolectomy in the FAP setting is discussed. CONCLUSION Periampullary cancer carries a significant risk in patients with FAP and proper endoscopic follow-up should be applied in this special patient group in order to manage ampullary manifestations of the disease in a timely manner.

INTRODUCTION Liver metastases from breast cancer (BCLM) confer poor survival. Liver resection in BCLM patients has been increasingly employed. AIM We undertook a systematic review to evaluate the role of hepatic resection in patients with breast cancer metastatic to the liver. MATERIALS & METHODS In total, 36 studies were overviewed. Patient populations, characteristics, morbidity, mortality and survival were documented. RESULTS Median overall survival was 41 months. Major morbidity was rare while 30-day postoperative mortality was near nil. CONCLUSION Liver surgery for BCLM can be performed with low mortality, acceptable morbidity and promising survival benefit in carefully selected patients.

Minimal invasive techniques have allowed for major surgical advances. We report our initial experience of performing total laparoscopic left hepatectomy (segments II-IV) with the Lotus (laparoscopic operation by torsional ultrasound) Ultrasonic Scalpel. The perioperative and postoperative courses of the young female patient were uneventful and she is in a good general condition without complaints 18 mo after surgery. To the best of our knowledge, this is the first total laparoscopic hemihepatectomy to be performed in Greece, as well as the first laparoscopic liver resection using Lotus shears.

Inflammatory myofibroblastic tumors (IMTs) of the breast represent extremely rare lesions. Due to the scarcity of reports, their natural history, recurrence, and metastatic potential remain poorly defined. We report on a case of a primary breast IMT in a postmenopausal female patient treated successfully with breast conserving surgery and review the literature pertaining to this rare entity.

Primary carcinoma of the male urethra accounts for less than 1% of malignancies in men. Mucinous adenocarcinoma of the urethra is extremely rare, and its biologic behavior is poorly understood. We present herein a rare case of mucinous urethral adenocarcinoma in a male patient with longstanding ulcerative colitis and multiple sclerosis. The patient presented with a voluminous pelvic mass; core biopsy of the lesion demonstrated a mucus-producing adenocarcinoma. Given the patients history of subtotal colectomy, preoperative diagnosis was oriented towards a rectal stump adenocarcinoma. The patient underwent a pelvic exenteration: surprisingly, histology marked the prostatic urethra as the primary lesion site.

Focal nodular hyperplasia (FNH) and hepatocellular adenoma (HA) are both benign hepatocellular lesions, presenting mainly in women of childbearing age in non-cirrhotic, non-fibrotic livers. Simultaneous occurrence of these two lesions is extremely rare. We herein report a case of a young female without any predisposing risk factors who presented to our emergency department complaining of acute abdominal pain. Imaging studies revealed a 6 cm lesion in the right hepatic lobe and a 2.5 cm lesion in the left hepatic lobe, respectively. In view of the patients symptoms and lack of a confirmed diagnosis based on imaging, we performed a bisegmentectomy V-VI and a wedge resection of the lesion in segment III by laparotomy. Postoperative course was uneventful and the patient was discharged on the fourth postoperative day. The pathology report demonstrated an HA in segments V-VI and FNH in segment III, respectively. Six months later, the patient remains asymptomatic with normal liver function tests, ultrasound and magnetic resonance imaging follow-up. To our best knowledge, this is the first case to describe simultaneous occurrence of HA and FNH without the presence of any known risk factors for these entities. The uncertainty in diagnosis and acuteness of presenting symptoms were established criteria for prompt surgical intervention.

Nonfunctioning symptomatic paraganglioma: Is there an optimal follow-up for patients with extra-adrenal benign paragangliomas

D. Mantas; A. Kandilis; Petros Charalampoudis

Paragangliomas are rare neuroendocrine neoplasms originating from the embryological neural crest. In most cases, they exhibit a benign behavior. Here we report a case of a small symptomatic para-aortic paraganglioma, which was completely removed surgically and a review of the available literature regarding the optimal follow-up of a benign paraganglioma, since no guidelines are currently available for this rare entity.

Visceral metastases from malignant melanoma (stage M1c) confer a very poor prognosis, as documented on the most recent revised version of the TNM/AJCC staging system. Emergency surgery for intra-abdominal complications from the disease is rare. We report on our 5-year single institution experience with surgical management of metastatic melanoma to the viscera in the emergent setting. From 2009 to 2013, 14 patients with metastatic melanoma were admitted emergently due to an acute abdomen. Clinical manifestations encompassed intestinal obstruction and bleeding. Surgical procedures involved multiple enterectomies with primary anastomoses in 8 patients, and one patient underwent splenectomy, one adrenalectomy, one right colectomy, one gastric wedge resection, one gastrojejunal anastomosis, and one transanal debulking, respectively. The 30-day mortality was 7 percent. Median follow-up was 14 months. Median overall survival was 14 months. Median disease free survival was 7.5 months. One-year overall survival was 64.2 percent and 2-year overall survival was 14.2 percent. Emergency surgery for metastatic melanoma to the viscera is rare. Elective curative surgery combined with novel cytotoxic systemic therapies is under investigation in an attempt to grant survival benefit in melanoma patients with visceral disease.

Background and Objectives: Laparoscopic liver resections (LLRs) have gained wider acceptance during the decade as safe and efficient procedures in the management of several benign and malignant diseases when performed by experienced surgeons. We report our initial institutional experience with LLRs performed by 1 certified hepatobiliary surgeon. Methods: Patients undergoing LLRs by 1 senior hepatobiliary surgeon in our Institution during the period from January 2012 through January 2017 were prospectively sampled and retrospectively analyzed for the purposes of this study. Results: Forty-two of 175 patients (24%) who had surgery for liver tumors underwent LLR. Median age was 64 years; median body mass index and Charlson comorbidity index were 27.3 kg/m2 and 6.5, respectively. Patients underwent resections for benign (n = 22) or malignant (n = 20) lesions. Median total operating time was 115 minutes and liver resections included: 1 left hepatectomy, 11 bisegmentectomies, 7 segmentectomies, 5 wide wedge resections, 1 left lateral sectionectomy combined with segmentectomy and radiofrequency ablation, 15 liver cyst unroofing, 1 laparoscopic drainage of a pyogenic liver abscess, and 1 laparoscopic drainage of a hepatic hydatid cyst. Blood transfusion was needed in 10 patients. Six patients (14%) had postoperative complications, none of which necessitated reoperation. None of the patients was admitted to the intensive care unit after surgery, and the median hospital stay was 4 days. The tumor-free resection margin was documented in all primary or secondary oncologic cases. Conclusions: Careful patient selection and compliance with the international recommendations are the keys for the successful introduction and evolution of an LLR program with a certified hepatobiliary surgeon with laparoscopic experience.

Synchronous Trifocal Colorectal Cancer

Petros Charalampoudis; Georgios C. Sotiropoulos; Stylianos Kykalos; Paraskevas Stamopoulos; Gregory Kouraklis

Synchronous colorectal cancers (SCRCs) have been increasingly diagnosed due to emerging diagnostic modalities. The presence of three or more synchronous colorectal cancers has, however, only rarely been reported. A 76-year-old white man presented for management of two concurrent colorectal adenocarcinomas in the left colon evidenced on total colonoscopy. Preoperative abdominal ultrasonography and thora-coabdominal computed tomography were negative for metastatic disease. The patient underwent an elective left hemicolectomy. The pathology report ultimately showed the presence of three moderately differentiated, distinct colorectal cancers. The patient experienced an uneventful recovery.
