One of the most serious, potentially life-threatening complications of laparoscopic sleeve gastrectomy (LSG) is staple-line leakage. Oversewing the LSG staple line vs buttressing it with bovine pericardial strips (BPS) to reduce perioperative bleeding and postoperative gastric leak was evaluated. From 2006 through 2011, 160 patients underwent LSG with suturing as the only staple-line reinforcement (Group A). From March 2010 through August 2012, 84 LSG patients had BPS incorporated into their last two stapler firings (Group B). Staple lines were evaluated perioperatively for bleeding, and patients were monitored for indications of staple-line leaks (peritonitis, abnormal output from the drain). In preoperative Group A and B, there were 117 (73.1%) vs. 56 (66.7%) females; mean age, 35.2 years (18.0-68.0) vs. 33.8 years (15.0-64.0); mean body mass index (BMI, kilograms per square meter), 42.5 (27.0-76.0) vs. 42.0 (30.0-58.0). Three months after surgery, mean BMI for Group A was 37.3 (-5.9); Group B, 35.2 (-7.3); at 6 months, 32.7 (-10.8) and 31.5 (-11.3; p < 0.001). Although there was no significant difference in perioperative blood loss, oversewn staple lines in Group A often required electrocautery to stanch bleeding; this was not required for Group B. In Group A, 15 patients (9.4%) developed complications; in Group B, five (6.0%; p = 0.46). Gastric fistula, verified by barium swallow, occurred in eight Group A patients (5.0%); in Group B, one (1.2%; p = 0.17). Relative to oversewing, staple-line buttressing with bovine pericardium was readily accomplished, safe, and associated with a lower staple-line leak rate.

HighlightsSince early postoperative nausea and vomiting are fairly common, a high index of suspicion was essential for the diagnosis.Taking into account the asymptomatic intrathoracic sleeve migration described in the literature, thoracic cuts of the CT Scan are essential in post sleeve evaluation.Sleeve gastrectomy might disrupt the lower esophageal sphincter pressure and aggravate a pre-existing asymptomatic weak sphincter.The only other 2 reported cases occurred in the setting of a hiatal hernia. In ours no hiatal defect was observed.

IntroductionLow grade fibromyxoid sarcoma (LGFMS)1 is a rare soft tissue tumor involving deep soft tissues of the extremities and trunk. Abdominal location is extremely uncommon in which the few cases published in the literature are characterized by slow tumoral progression and long recurrence-free intervals.MethodsWe report the first case of an intra-abdominal LGFMS which was discovered incidentally in a 42-year-old woman presenting diffuse peritoneal nodules and hepatic metastasis on CT and MRI scans.ResultsThe patient was successfully treated through conservative measures and remained asymptomatic at the 48 month follow-up.ConclusionsThis is the first reported case of LGFMS with peritoneal and hepatic metastases. Despite the discovery of an advance disease at exploration, the patient who refused a major surgical operation presents an uneventful follow-up and long term survival.
