Visceral Block in Bariatric Surgery: A Pilot Double Blind Randomized Clinical Study.

BACKGROUND: Local anesthetics are used in various sites and mechanisms to maximize perioperative analgesia and reduce opioid use and side effects. Pain management in the bariatric setting is challenging and the efficacy of local anesthetics intraoperatively is under current evaluation. OBJECTIVES: To determine the safety and efficacy of a new intra-abdominal anesthetic technique performed during laparoscopic bariatric operations: visceral block. METHODS: During this prospective randomized double-blinded pilot study, 16 patients undergoing bariatric surgery were treated with the injection of ropivacaine to the anterior esophagogastric junction fat, and 15 were injected with saline as control. RESULTS: The procedure was shown to be safe, and no adverse events nor side effects were encountered. A non-statistically significant trend toward the use of a non-opioid analgesia was documented during the first postoperative hours. CONCLUSIONS: Visceral block is a safe and feasible intraoperative procedure. A trend toward its efficacy warrants future larger scale studies.

Expectant management in delayed presentation of war casualties with penetrating abdominal trauma.

INTRODUCTION: While the management of acute civilian abdominal injuries is well established, The literature regarding the management of battle-related abdominal injuries presented in a delayed fashion is scarce. The objective of this study was to investigate the safety of non-operative management approach in delayed evacuation of battle-related abdominal injuries. METHODS: Clinical records of thirty-seven hemodynamically normal patients with battle related injuries and Computed Tomography (CT) findings of penetrating abdominal trauma were retrospectively studied. RESULTS: All 37 patients suffered penetrating abdominal injuries during the civil war in Syria. In this complex scenario, the casualties presented after a minimum 12-hour delay to our hospital. All patients had abnormal abdominal CT scans with no clinical peritoneal signs. Twenty-one [of the 37] patients exhibited 29 hard signs on CT scan. Of these, 17 patients were treated non-operatively and 4 underwent exploratory laparotomy (of which 2 were non-therapeutic). Sixteen patients exhibited a total of 75 soft signs on CT scan; 15 were treated non-operatively and one underwent non-therapeutic laparotomy. No complications were recorded in either the operative or non-operative groups. In total, 32 patients (86%) were treated non-operatively. Five patients (14%) underwent exploratory laparotomy (3 of which were non-therapeutic). Length of stay was dependent on the unique requirements of each individual patient as determined by the state department for returning across the border. CONCLUSION: We propose that in battle related casualties, acute survivable penetrating abdominal trauma may be safely treated non-operatively in selected patients who are hemodynamically normal and in whom there is an absence of abdominal pain or tenderness on repeated clinical assessment.
