Aims: To compare the perioperative parameters and excess weight loss between patients operated by laporoscopic Roux-en-Y gastric bypass (LRYGB), as a primary operation or a revisional, for insufficient weight loss after vertical banded gastroplasty (VBG) or adjustable gastric banding (AGB). Methods: A retrospective analysis of all patients who u...

Background Vertically banded gastroplasty or adjustable gastric banding often result in weight regain, complications, or side effects. Failed restrictive bariatric procedures can be converted in revisional laparoscopic Roux-en-Y gastric bypass (LRYGB). This study aimed to compare weight loss, evolution of comorbidities, and quality of life (QOL) b...

Background: Portal vein system thrombosis (PVT) is an infrequent but potentially serious complication after laparoscopic splenectomy. Patients with β-thalassemia are at higher risk as they have splenomegaly and hypercoagulability. Subjects and methods: Forty-eight β-thalassemia patients who underwent hand-assisted laparoscopic splenectomy or lap...

Background: Early detection and treatment of complications after laparoscopic sleeve gastrectomy (LSG) are mandatory. This study aimed to evaluate C-reactive protein (CRP), white blood cell (WBC) count, and neutrophil (NEU) count in relation to the early diagnosis of major surgical complications after LSG. Methods: A prospective study of 177 pat...

Minimally invasive approaches have gradually evolved to become the golden standard in several surgical procedures. Laparoscopic splenectomy has been performed for several years offering similar or even better results compared to open surgery. Approaches in laparoscopic splenectomy regarding the positioning of the patient and the operative procedure...

Staple-line reinforcement has been used with promising results in laparoscopic gastric bypass in order to reduce leakage, increase staple-line integrity, and diminish staple-site bleeding. The purpose of this study was to determine if staple-line reinforcement with bovine pericardial strips reduces surgical complications of laparoscopic sleeve gast...

Transanal excision of rectal polyps with laparoscopic instrumentation and a single incision laparoscopic port is a novel technique that uses technology originally developed for abdominal procedures from the natural orifice of the rectum. Transanal endoscopic microsurgery (TEM) is a well established surgical approach for certain benign or early mali...

To our knowledge, the predictive value of procalcitonin for bowel strangulation has been evaluated in only 2 experimental studies that had conflicting results. The objective of this study was to evaluate the value of procalcitonin for early diagnosis of intestinal ischemia and necrosis in acute bowel obstruction. We performed a prospective study of...

Background: Bariatric surgery is nowadays an evolving field. New procedures and techniques, long term results and complication rates have not been well studied yet. Aims: To evaluate the effectiveness of endoscopic stent placement in treating stapling line leakage of laparoscopic sleeve gastrectomy.

The isolated use of Doppler-guided haemorrhoidal artery ligation (DGHAL) may fail for advanced haemorrhoids (HR; grades III and IV). Suture haemorrhoidopexy (SHP) and mucopexy by rectoanal repair (RAR) result in haemorrhoidal lifting and fixation. A prospective evaluation was performed to evaluate the results of DGHAL combined with adjunctive proce...

Vacuum-assisted breast biopsy is a minimally invasive technique that has been used increasingly in the treatment of mammographically detected, non-palpable breast lesions. Clip placement at the biopsy site is standard practice after vacuum-assisted breast biopsy. We present the case of a 62-year-old woman with suspicious microcalcifications in her...

To present the initial Greek experience with vacuumassisted breast biopsy (VABB) in the diagnosis of nonpalpable solid mammographic lesions without microcalcifications. We performed 83 VABB procedures (using a Fischer table and 11-guage Mammotome probes) in an 18- month period on women with nonpalpable solid breast tumors. We performed VABB procedu...

Vacuum-assisted breast biopsy is a minimally invasive technique used increasingly for the assessment of mammographically detected, non-palpable breast lesions. The effectiveness of vacuum-assisted breast biopsy has been demonstrated on lesions both with and without microcalcifications. Given that the position of the lesion represents a major factor...

The aim of this study was to evaluate the outcome of laparoscopic cholecystectomy (LC) in octogenarians with complicated gallstone disease. This study was a retrospective analysis of prospectively collected data of 51 patients aged 80 years or older who underwent an LC for complicated gallstone disease between 2001 and 2006. This group was compared...

Intrathoracic colon herniation after esophagectomy is rare. Furthermore, fecopneumothorax is an extremely infrequent clinical entity. We believe this is the first report in the literature of a patient with fecopneumothorax due to diverticular perforation of intrathoracically herniated transverse colon 2 months after transthoracic esophagectomy and...

Intussusception in adults is rare. The clinical picture of intussusception in adults is subtle and the diagnosis is, therefore, elusive. The presence of a structural abnormality in the great majority of the adult cases mandates high clinical suspicion. Gastrointestinal lipomas are rare benign tumors and intussusception due to a gastrointestinal lip...

Breast lymphoma, either as a manifestation of primary extranodal disease or as secondary involvement, is a rare malignancy, and its diagnosis, prognosis, and treatment have not been clearly defined. On the other hand, Vacuum-assisted breast biopsy (VABB) is a minimally invasive technique with ever-growing use for the diagnosis of mammographically d...

Breast cancer is usually associated with metastases to lungs, bones and liver. Breast carcinoma metastasizing to the gallbladder is very rare. A 59-year-old woman presented with bilateral synchronous breast lesions. A palpable, retroareolar solid lesion of diameter equal to 5 cm was present in the right breast, and a newly developed, non-palpable l...

To identify and analyze the clinical presentation, management and outcome of patients with acute mechanical bowel obstruction along with the etiology of obstruction and the incidence and causes of bowel ischemia, necrosis, and perforation. This is a prospective observational study of all adult patients admitted with acute mechanical bowel obstructi...

beta-Thalassemia patients have splenomegaly significant enough to require splenectomy; furthermore, these patients also often require concurrent procedures. Between January and October 2005, seven patients with beta-thalassemia underwent hand-assisted laparoscopic splenectomy with cholecystectomy, appendectomy, and liver biopsy with the hand-port d...

Laparoscopic vertical banded gastroplasty (LVGB), is a safe and efficient bariatric operation, with low intraoperative complications. We report an unusual cause of conversion of a LVGB to an open procedure due to the fracture of the spike of the circular stapler during gastric penetration.
