Longitudinal Gastrectomy as a Treatment for the High-Risk Super-Obese Patient

Background: Bariatric surgery in patients with significant co-morbid conditions is associated with increased perioperative risk. Methods: From 1995-2001, 795 patients were operated upon at our institution for the diagnosis of morbid obesity. Of these, 671 (84.4%) had the duodenal switch (DS) procedure. Longitudinal gastrectomy (LG) entails a greater curvature linear gastrectomy creating a gastric tube with a volume of 100 ml along the lesser curvature of the stomach. This procedure was performed for 21 patients (median age 50.5, median BMI 56). 9 patients were offered LG preoperatively because of their known high perioperative risks. 12 patients were initially planned for DS, but the procedure was limited to LG alone because of either unexpected intraoperative findings (n=9) or intraoperative hemodynamic instability (n=3). 5 patients developed complications, and there were no deaths. Results: 19 out of 21 patients were available for a median follow-up of 17.5 months (6.25-20.25). Median weight loss and median %EWL at 12 months were 44.5 kg and 45.1%, respectively. Estimated daily dietary volume at 1 year was 35% of preoperative values. Of 10 patients followed for ≥ 1 year, 4 of 10 achieved more than 50% EWL and 8 patients were taking less or were completely off medications for diabetes, hypertension and congestive heart failure. Weight loss plateaued at 1 year for the majority of patients. Conclusions: LG is a safe and effective option for high-risk morbidly obese patients. Weight reduction is accomplished by limitation of caloric intake. LG can be offered to high-risk morbidly obese patients as an interim procedure to help decrease perioperative risk before DS.

Achalasia in the Context of Morbid Obesity: a Rare but Important Association

Background: The simultaneous occurrence of achalasia and morbid obesity is rare. Nevertheless, the surgical therapy of morbid obesity may be harmful, if undiagnosed achalasia were left untreated. We report the clinical presentation and response to treatment of achalasia in the context of morbid obesity. Methods: From 1998 to 2002, 638 patients underwent surgery for morbid obesity. Preoperative upper gastrointestinal radiography was performed in all patients. Three patients had manometric confirmation of achalasia. The characteristic symptoms were recurrent episodes of regurgitation, chronic cough and aspiration. No patient reported dysphagia or recent weight loss. Results: All patients had a duodenal switch procedure and in two a concurrent Heller myotomy was added. The other patient required a Heller myotomy after a duodenal switch had been performed, because the motility study was initially misinterpreted. All patients reported gradual resolution of presenting symptoms after myotomy. Conclusions: A careful symptomatic history focusing on aspiration, regurgitation and cough may identify the unusual combination of achalasia and morbid obesity. Treatment of morbid obesity alone may lead to progression of pulmonary symptoms.

The pattern of thoracic trauma after suicide terrorist bombing attacks

BACKGROUND The worldwide escalation in the volume of suicide terrorist bombing attacks warrants special attention to the specific pattern of injury associated with such attacks. The goal of this study was to characterize thoracic injuries inflicted by terrorist-related explosions and compare pattern of injury to penetrating and blunt thoracic trauma. METHODS Prospectively collected database of patients with chest injury who were admitted to Hadassah Hospital Level I trauma centre, in Jerusalem, Israel, from October 2000 to December 2005. Patients were divided into three groups according to the mechanism of injury: terrorist explosions (n = 55), gunshot wounds (GSW; n = 78), and blunt trauma (n = 747). RESULTS There were many female victims after suicide bombing attacks (49.1%) compared with GSW (21.8%) and blunt trauma (24.6%; p = 0.009). The number of body regions injured was significantly higher in the terror group compared with the GSW and blunt groups (median, 4, 2, and 3, respectively, p < 0.0001). The pattern of chest injury after suicide bombing attacks was caused by a unique combination of the effects of the blast wave and penetrating shrapnel. More than half (52.7%) of the terror victims suffered from lung contusion and 25 (45.5%) required tube thoracostomy. Five patients (9.1%) underwent thoracotomy for lung lacerations (n = 3), injury to great vessels (n = 2), cardiac lacerations (n = 1), and esophageal injury (n = 1). Penetrating shrapnel was the mechanism of injury in all these cases. CONCLUSIONS Injury inflicted by terrorist bombings causes a unique pattern of thoracic wounds. Victims are exposed to a combination of lung injury caused by the blast wave and penetrating injury caused by metallic objects.

Percutaneous "stepped" drainage technique for infected pancreatic necrosis.

Introduction Aggressive surgical pancreatic debridement remains the standard of care, may require multiple abdominal explorations and is associated with high mortality. We have introduced the stepped technique of percutaneous treatment of infected peripancreatic fluid collections. Methods We performed a retrospective review of patients with severe infected necrotizing pancreatitis who were managed percutaneously. Culture results, number of radiological interventions, length of stay, and complications were recorded. Results There were 8 patients with a median number of Ransons criteria of 4.5. Sixty invasive procedures were performed. A median number of two separate catheter sites per patient were necessary for the removal of necrotic material. Median duration of percutaneous intervention was 71.5 days with complete removal of necrotic material and resolution of infected collections in all patients. Conclusions Surgeons and interventional radiologists should be familiar with this evolving technique which is less invasive then surgery, but may prolong the time necessary for complete resolution.

Pre-hospital and admission parameters predict in-hospital mortality among patients 60 years and older following severe trauma

The incidence of geriatric trauma is rising with an increased life expectancy and a more active lifestyle among the elderly. The aim of this study was to describe the different patterns of injury with increased age in severely injured elderly patients and to identify predictors of in-hospital mortality.

Posttraumatic stress disorder in hospitalized terrorist bombing attack victims

BACKGROUND Posttraumatic stress disorder (PTSD) is a psychiatric disorder that results from exposure to a traumatic event and consists of intrusive and unwanted recollections; avoidance followed by emotional withdrawal; and heightened physiologic arousal. Hospitalized victims of suicide bombing attacks (SBAs) are unique because of the circumstances and severity of their injuries, which could affect the occurrence and delay the recognition of PTSD. Our objectives were to evaluate the prevalence and severity of PTSD among hospitalized SBA victims and to assess variables of physical injury as risk factors for the development of PTSD. METHODS Forty-six hospitalized SBA victims were evaluated for PTSD using the PTSD symptom scale self-report questionnaire by phone. Demographic and medical data regarding the severity and type of injury and medical treatment were collected from medical files. Injury Severity Score was used to assess severity of physical injury. RESULTS Twenty-four of 46 (52.2%) hospitalized SBA victims developed PTSD. Presence of blast lung injury was significantly higher in the PTSD group compared with the non-PTSD group (37.5% versus 9.1%, respectively; p < 0.04). There was no significant difference in Injury Severity Score between PTSD and non-PTSD groups. Blast lung injury and intracranial injury were found to be positive predictors of PTSD (odds ratio, 125 and 25, respectively). No correlation was found between the length of stay, length of intensive care unit stay, or severity of physical injuries and the severity of PTSD. CONCLUSIONS Hospitalized victims of SBA are considerably vulnerable to develop PTSD. Victims should be monitored closely and treated in conjunction with their physical treatment. Blast lung injury and intracranial injury are predictors of PTSD.

Civilian casualties of terror-related explosions: the impact of vascular trauma on treatment and prognosis

Objectives A high prevalence (10%) of vascular trauma (VT) was previously described in terror-related trauma as compared with non–terror-related trauma (1%), in a civilian setting. No data regarding outcome of VT casualties of improvised explosive device (IED) explosions, in civilian settings, are available. The aim of the current study is to present the prognosis of civilian casualties of IED explosions with and without VT. Methods A retrospective analysis of the Israeli National Trauma Registry was performed. All patients in the registry from September 2000 to December 2005 who were victims of explosions were included. These patients were subdivided into patients with VT (n = 109) and non-VT (NVT) (n = 1,152). Both groups were analyzed according to mechanism of trauma, type and severity of injury, and treatment. Results Of 1,261 explosion casualties, there were 109 VT victims (8.6%). Patients with VT tended to be more complex, with a higher injury severity score (ISS): 17.4% with ISS 16 to 24 as compared with only 10.5%. In the group of critically injured patients (ISS, 25–75), 51.4% had VT compared with only 15.5% of the NVT patients. As such, a heavy share of hospitals’ resources were used—trauma bay admission (62.4%), operating rooms (91.7%), and intensive care unit beds (55.1%). The percentage of VT patients who were admitted for more than 15 days was 2.3 times higher than that observed among the NVT patients. Lower-extremity VT injuries were the most prevalent. Although many resources are being invested in treating this group of patients, their mortality rate is approximately five times more than NVT (22.9% vs. 4.9%). Conclusions Vascular trauma casualties of IED explosions are more complex and have poorer prognosis. Their higher ISS markedly increases the hospital’s resource utilization, and as such, it should be taken into consideration either upon the primary evacuation from the scene or when secondary modulation is needed in order to reduce the burden of the hospitals receiving the casualties.
