Introduction: Small bowel obstruction (SBO) is a frequent complication after laparoscopic Roux-en-y gastric bypass (LRYGB).

Objectives: We wanted to evaluate the effect of closure of the mesenteric defects on the incidence of SBO and postoperative complications after LRYGB. Furthermore, we wanted to identify possible risk factors for SBO.

Therapy of breast cancer brain metastases: challenges, emerging treatments and perspectives.

Brain metastases are the most common central nervous system tumors in adults, and incidence of brain metastases is increasing due to both improved diagnostic techniques (e.g. magnetic resonance imaging) and increased cancer patient survival through advanced systemic treatments.

Acute skin allergy to thermoplastic mask used for patient immobilization during radiation therapy: a case report.

Background: Radiosurgical treatments of brain tumors, vascular malformations, and functional disorders are more and more frequently used. Gamma Knife irradiation with the Icon system necessitates the use of a thermoplastic mask for head immobilization during treatment. Acute cutaneous allergy to thermoplastic masks has never been reported.

[Early postsurgical temozolomide treatment in newly diagnosed bad prognosis glioblastoma patients: Feasibility study].

Introduction: Despite the combined adjuvant treatment of radiotherapy plus chemotherapy with temozolomide (TMZ) followed by 6 cycles of temozolomide after surgery, the prognosis of patients with glioblastoma remains poor. We conducted a monocentric prospective study to explore the tolerance and potential efficacy of an early temozolomide cycle after surgery.

Method: Patients with newly diagnosed glioblastoma (unmutated IDH1) and of poor prognosis (age>50 years, biopsy or partial resection or unmethylated MGMT promoter) were prospectively included from June 2014 to 2017.

A case of pseudorenal failure - spontaneous rupture of the urinary bladder.

A 64-year old woman was admitted to the hospital for severe abdominal pain and distension after gardening and chopping wood the day before. She had a medical history of superficial transitional cell carcinoma (TCC) of the urinary bladder and a laparoscopic nefro-ureterectomy for an invasive TCC of the upper urothelial tract in 2012. Clinical examination showed an acute abdomen.

Laparoscopic parenchymal preserving hepatic resections in semiprone position for tumors located in the posterosuperior segments.

Introduction: All patients who underwent laparoscopic liver resections in the posterosuperior segments (LPSS) at our center were positioned in semiprone since August 2011. The aims of this study were to assess differences in perioperative outcomes between laparoscopic left lateral sectionectomies (LLLS) performed in supine position and LPSS in semiprone position.

Methods: We reviewed our prospectively collected database of all liver resections performed between January 2012 and January 2015.

The influence of propofol and sevoflurane on intestinal motility during laparoscopic surgery.

Background: Volatile anaesthetics have an influence on small bowel peristalsis during laparoscopic surgery. A recent study concluded that desflurane increased intestinal motility compared to sevoflurane. Hence, a desflurane-based anaesthesia protocol may reduce surgical exposure during intestinal suturing or stapling due to small bowel hyperperistalsis.

Repeat Gamma Knife surgery for vestibular schwannomas.

Background: Gamma Knife (GK) surgery is a recognized treatment option for the management of small to medium-sized vestibular schwannoma (VS) associated with high-tumor control and low morbidity. When a radiosurgical treatment fails to stop tumor growth, repeat GK surgery can be proposed in selected cases.

Methods: A series of 27 GK retreatments was performed in 25 patients with VS; 2 patients underwent three procedures.

SILS sigmoidectomy versus multiport laparoscopic sigmoidectomy for diverticulitis.

Background And Objectives: In this single-institution study, we aimed to compare the safety, feasibility, and outcomes of single-incision laparoscopic sigmoidectomy (SILSS) with multiport laparoscopic sigmoidectomy (MLS) for recurrent diverticulitis.

Methods: Between October 2011 and February 2013, 60 sigmoidectomies were performed by the same surgeon. Forty patients had a MLS and 20 patients had a SILSS.

Value of preoperative esophagogastroduodenoscopy in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass.

Background: Roux-en-Y gastric bypass hinders post-operative endoscopic evaluation of the upper gastrointestinal tract. Our aims were to determine the prevalence of preoperative endoscopic findings in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) and to determine the proportion of patients in which these findings changed surgical management.

Methods: We retrospectively evaluated electronic medical records of patients undergoing esophagogastroduodenoscopy (EGD) with routine antral biopsy for Helicobacter pylori (HP) detection, prior to LRYGB between January 2003 and January 2010 at our institution.

Phase I trial combining temozolomide plus lapatinib for the treatment of brain metastases in patients with HER2-positive metastatic breast cancer: the LAPTEM trial.

Background: Brain metastases (BMs) pose a clinical challenge in breast cancer (BC). Lapatinib or temozolomide showed activity in BM. Our study assessed the combination of both drugs as treatment for patients with HER2-positive BC and BM.

Hearing preservation and tumour control after radiosurgery for NF2-related vestibular schwannomas.

Objectives: We analyzed the effects of stereotactic radiosurgery on tumour control and cranial nerve function in patients with vestibular schwannomas (VS) secondary to neurofibromatosis type 2 (NF2). Irradiation was performed with a Gamma Knife, model C equipped with a high-precision, robotized positioning system (APS).

Transvaginal pure NOTES sigmoid resection using a single port device.

Background: The amount of published experience using natural orifice transluminal endoscopic surgery (NOTES) is increasing. However, approximately half of the technical approaches described include NOTES as part of a hybrid procedure. Colonic resections performed using NOTES have mainly been described using a hybrid approach.

[Treatment of brain metastases].

Brain metastases (BC) are the cause of important mortality and morbidity in cancer patients. Corticoids and Whole Brain Radiotherapy (WBRT) remains the standard treatment but, at the long-term, the results are disappointing. In patients with a single metastase, the survival and the Quality of Life (QoL) can be improved by surgery combined with WBRT.

Randomized clinical trial on the influence of anaesthesia protocol on intestinal motility during laparoscopic surgery requiring small bowel anastomosis.

Background: Hyperperistalsis of the small bowel during laparoscopic surgery may cause mucosal prolapse and reduce exposure, making laparoscopic suturing or stapling more demanding for the surgeon. Although it is commonly accepted that both opioids and volatile anaesthetics induce intestinal paralysis, intestinal hyperactivity during anaesthesia is not uncommon. This randomized trial investigated the effect of different volatile anaesthetics on intestinal motility and the impact on surgeon satisfaction.

Hearing outcome after gamma knife radiosurgery for vestibular schwannoma: a prospective Belgian clinical study.

Introduction: Leksel Gamma Knife (LGK) radiosurgery is a safe and efficient therapeutic approach for vestibular schwannoma (VS) with low side effects. The goal of radiosurgery is not necessarily to cause significant tumour necrosis or to obtain a complete radiographic response, but to halt the tumour's growth permanently through its biological elimination. The 2 major aims of radiosurgery for VS are long-term tumour control and functional hearing preservation.

Indications, safety, and feasibility of conversion of failed bariatric surgery to Roux-en-Y gastric bypass: a retrospective comparative study with primary laparoscopic Roux-en-Y gastric bypass.

Background: Roux-en-Y gastric bypass (RYGB) is considered the "gold standard" revision procedure. The purpose of this study was to compare the surgical outcome of primary laparoscopic RYGB (pLRYGB) to revisional open or laparoscopic Roux-en-Y gastric bypass surgery (rRYGB).

Methods: A retrospective analysis of all patients who underwent pLRYGB or rRYGB from January 2003 to December 2009 has been performed.
