    Abstract Irreversible electroporation (IRE) is a non-thermic ablation therapy which has been proposed for locally advanced pancreatic adenocarcinoma (LAPC) as well as for the local control of other types of tumors (kidney or liver). Its use has been extended in the last few years worldwide. Its advantage over other ablation techniques is that it only affects the lipids bilayer of the cell membrane avoiding vascular damage. Safety and viability have been demonstrated in recent studies. Overall survival seems (OS) to improve when it is combined with chemotherapy compared to chemotherapy with or without radiotherapy. Clinical trials should confirm these encouraging data.

    Abstract Introduction: There are few studies that investigate the usefulness of the preoperative intragastric balloon (IGB). This study will evaluate if pre-surgical weight loss with IGB reduces morbidity and mortality after surgery.
    Method: Prospective randomised study of patients with morbid obesity treated with gastric bypass or vertical gastrectomy, with two arms: the balloon arm (B-arm), where an IGB was inserted within the 6 months before surgery, and the control arm (C-arm).
    Results: The study included 66 patients: 65.6% women, 69.6% with bypass. Age: 43 years (SD 10.2) B-arm and 42.6 years (SD 9.2) in the C-arm. We found 34.4% therapeutic failures in IGB. The mean body weight loss, %EWL and BMI reduction before surgery was 16.2 kg (SD 9.84) B-arm versus 4.7 (SD 8.70) in the C-arm, 23.6% versus 4.7% (p < 0.001) and 6.04 versus 1 (p < 0.001), respectively. The hospital stay was 7 days (p
    Conclusions: The preoperative balloon does not achieve a reduction in the post-surgical morbidity, nor does it reduce the hospital stay or rate of re-operations. The balloon achieves a higher weight loss result when compared to a diet programme, its added cost must also be given due consideration.
    Trail registry: This study has been registered on ClinicalTrials.gov with the Identifier: NCT01998243 (November 28, 2013).

    Abstract Background: Surgery has been the method most widely used to manage the extraction of gastric bands with inclusion as a late complication of bariatric surgery; however, surgical extraction entails morbidity and limits future surgical procedures. The development of endoscopic techniques has provided an important means of improving the treatment of this complication, enabling minimally invasive and safe procedures that have a high success rate.
    Methods: A retrospective analysis was conducted of patients who had laparoscopic gastric banding complicated by intragastric migration and were treated endoscopically. A technique already described for managing this complication was employed. An MTW Endoskopie Dormia basket for mechanical lithotripsy or a standard 0.0035-in guidewire was placed around the band, and an MTW Endoskopie emergency lithotripter was used to section it, after which the band was extracted with a standard polypectomy snare. Also analyzed were the initial symptoms of patients with this complication, the mean time from surgery to development of the event, the success rate of endoscopic treatment, and complications, Results: A total of 127 patients had undergone gastric banding surgery in our Bariatric Surgery Center; of these, 12 patients (9.4 %) developed a complication such as intragastric migration of the band. Weight gain and pain were the main symptoms in 11 patients (92 %), and the mean time to the development of symptoms was 51.3 months. A single endoscopic treatment was successful in 7 of 9 patients (78 %). Only 1 complication, involving ventilation during anesthesia, occurred; no other adverse events were recorded.
    Conclusions: The endoscopic extraction of bands with inclusion is feasible and can be performed easily and successfully. The procedure is available in all hospitals and has a low incidence of related complications, so that unnecessary surgical procedures can be avoided.

    Title translation Sinistral portal hypertension with bleeding gastric varices as initial manifestation of renal-cell carcinoma.
    Abstract We report a clinic case of renal-cell carcinoma presenting as sinistral portal hypertension; a clinical syndrome consisting of esplenic vein thrombosis manifested as isolated gastric varices with patent portal vein and normal hepatic function. The most frequent cause of this syndrome is pancreatic pathology. Renal-cell carcinoma is characterized by a wide variety of symptoms as initial manifestation. In our case, the patient developed a massive gastrointestinal bleeding secondary to isolated gastric varices caused by splenic vein thrombosis due to extrinsic compression by a hypernephroma that infiltrated the pancreas.

    Title translation Surgical treatment of sclerosing encapsulating peritonitis.
    Abstract Objectives: Sclerosing encapsulating peritonitis (SEP) or abdominal cocoon is a rare disease characterized by the formation of a fibrocollagenous membrane that wraps around the loops of the small bowel, producing obstruction. We present the results of the surgical treatment of this disease in three patients with chronic renal failure who developed SEP during the course of peritoneal dialysis (PD) and provide a literature review on the subject aimed at the general surgeon.
    Patients and method: In our area, the PD program treated 150 patients in 14 years, with seven cases of suspected SEP. In three patients, exploratory laparotomy was required. Clinical data, diagnostic imaging tests, type of surgery, immediate postoperative course, and status of the patient during subsequent follow-up are described.
    Results: In one of the three patients, bowel obstruction led to perforation requiring resection with anastomosis; the postoperative course was complicated and the patient died. In the remaining two patients, elective surgery was performed with the aim of removing the capsule enclosing the intestinal loops. In both patients the immediate postoperative course was favorable, although recurrence of intestinal encapsulation occurred in one patient.
    Conclusions: The success of surgery in this disease is determined by the technique used. The correct technique consists of freeing the adhesions and extirpating of the capsule as far as possible. Perforation, as well as resection and intestinal anastomosis, significantly increase mortality.

    Title translation Adenocarcinoma in a choledochal cyst. Report of a case and review of the literature.
    Abstract We present a case of cancer of a choledochal cyst in a patient with antecedents of cholecystectomy, who complained of pain in the right hypochondrium. Echography and CAT disclosed a cystic mass of biliary location, and the diagnosis was confirmed by intraoperative cholangiography and biopsy of the cyst margin. Cysto-jejunostomy on a Roux-en-Y loop was performed. The patient survived 11 months and died of tumoral dissemination. We reviewed 130 cases of cancer of a choledochal cyst published up until 1986 and possible etiopathogenic causes, and we discuss the diagnostic problems and related treatment.
