Abstract
Nutcracker esophagus (NE), Jackhammer esophagus (JHE), distal esophageal spasm (DES), and hypertensive lower esophageal sphincter (HTLES) are defined by esophageal manometric findings. Some patients with these esophageal motility disorders also have abnormal gastroesophageal reflux. It is unclear to what extent these patients' symptoms are caused by the motility disorder, the acid reflux, or both. The aim of this study was to determine the effectiveness of laparoscopic Nissen fundoplication (LNF) on esophageal motility disorders, gastroesophageal reflux, and patient symptoms. Between 2007 and 2013, we performed high-resolution esophageal manometry on 3400 patients, and 221 patients were found to have a spastic esophageal motility disorder. The medical records of these patients were reviewed to determine the manometric abnormality, presence of gastroesophageal symptoms, and amount of esophageal acid exposure. In those patients that underwent LNF, we compared pre- and postoperative esophageal motility, gastroesophageal symptom severity, and esophageal acid exposure. Of the 221 patients with spastic motility disorders, 77 had NE, 2 had JHE, 30 had DES, and 112 had HTLES. The most frequently reported primary and secondary symptoms among all patients were: heartburn and/or regurgitation, 69.2%; respiratory, 39.8%; dysphagia, 35.7%; and chest pain, 22.6%. Of the 221 patients, 192 underwent 24-hour pH monitoring, and 103 demonstrated abnormal distal esophageal acid exposure. Abnormal 24-hour pH monitoring was detected in 62% of patients with heartburn and regurgitation, 49% of patients with respiratory symptoms, 36.8 % of patients with dysphagia, and 32.6% of patients with chest pain. Sixty-six of the 103 patients with abnormal 24-hour pH monitoring underwent LNF. Thirty-eight (13NE, 2JHE, 6 DES, and 17 HTLES) of these 66 patients had a minimum of 6-month postoperative follow-up that included clinical evaluation, esophageal manometry, and 24-hour pH monitoring. Postoperatively, all 38 patients had normal distal esophageal acid exposure. Of these 38 patients, symptoms resolved in 28 and improved in 10. Of six patients (one with NE, two JHE, and three with HTLES) that underwent postoperative esophageal manometry, five exhibited normal motility. Typical reflux symptoms are common among patients with esophageal hypermotility disorders. Abnormal 24-hour pH monitoring is present in the majority of patients with who report typical reflux symptoms and almost half of patients who report respiratory symptoms. Conversely, the majority of patients who report dysphagia or chest pain have normal distal esophageal acid exposure. Based on a small number of patients in this study, it also appears that motility disorders often improve after LNF. LNF is associated with resolution or improvement in reflux related symptoms and esophageal motility parameters in patients exhibiting abnormal esophageal acid exposure. This suggests that patient symptoms are due to abnormal acid exposure and not the motility disorder.

Abstract
Gastroesophageal reflux disease (GERD) can be difficult to diagnose - symptoms alone are often not enough, and thus, objective testing is often required. GERD is a manifestation of pathologic levels of reflux into the esophagus of acidic, nonacidic, and/or bilious gastric content. However, in our current evidence-based knowledge approach, we only have reasonable outcome data in regards to acid reflux, as this particular type of refluxate predictably causes symptoms and mucosal damage, which improves with medical or surgical therapy. While there are data suggesting that nonacid reflux may be responsible for ongoing symptoms despite acid suppression in some patients, outcome data about this issue are limited. Therefore, this working group believes that it is essential to confirm the presence of acid reflux in patients with 'refractory' GERD symptoms or extraesophageal symptoms thought to be caused by gastroesophageal reflux before an escalation of antireflux therapy is considered. If patients do not have pathologic acid reflux off antisecretory therapy, they are unlikely to have clinically significant nonacid or bile reflux. Patients who do not have pathologic acid gastroesophageal reflux parameters on ambulatory pH monitoring then: (i) could attempt to discontinue antisecretory medications like proton pump inhibitors and H2-receptor antagonists (which are expensive and which carry risks - i.e. C. diff, etc.); (ii) may undergo further evaluation for other causes of their esophageal symptoms (e.g. functional heartburn or chest pain, eosinophilic esophagitis, gastroparesis, achalasia, other esophageal motor disorders); and (iii) can be referred to an ear, nose, and throat/pulmonary/allergy physician for assessment of non-GERD causes of their extraesophageal symptoms.

Abstract
The current state of research into the etiology of achalasia only allows for speculation. To date, several studies have been performed investigating genetic, immune, and infectious disease mechanisms; however, none of these have been conclusive. Further research into this topic is warranted given the severity of the disease, and it may be possible that all of these mechanisms are involved in the pathophysiology of the disease.

Abstract
Esophagectomy is associated with substantial morbidity and mortality, yet it is the only modality that offers the possibility of cure for esophageal and gastroesophageal junction (E-GEJ) adenocarcinoma. Several minimally invasive techniques have been developed to decrease the morbidity of the operation, but to date, the results have not led to its wide adoption in part due to their complexity. We developed a technique of laparoscopic-assisted transhiatal esophagectomy (LA-THE) with the idea of preserving some of the advantages of the minimally invasive approach while eliminating the degree of complexity and the time required to complete the operation solely using laparoscopy. The course of all patients who underwent LA-THE for E-GEJ adenocarcinoma at the University of Washington Medical Center was determined by analysis of all hospital records to determine perioperative variables, complications, and survival. Patients were also given a follow-up survey in order to assess long-term health-related quality of life (Gastrointestinal Quality of Life Index or GIQLI). Seventy-two patients underwent LA-THE between 1995 and 2007. Median age was 64 years (range, 42-83 years), and the median body mass index was 28 (range 17-35). Twenty-eight tumors (39%) were categorized as Siewert I, 41 (57%) as Siewert II, and 3 (4%) as Siewert III. Median operative time was 299min (range, 212-700min). All the resections were R-0. The median number of lymph nodes harvested was 11 (range, 2-32). Using the Dindo-Clavien classification of surgical complication, we had a total of 48 postoperative complications in 37 patients: 26 (53%) grade I, 20 (41%) grade II, 1 (2%) grade IIIb, 1 (2%) grade IVb, and 1 (2%) grade V complications. Median length of hospital stay was 9 days (range, 7-58 days). One patient (1.4%) died within 30 days. Overall, 3- and 5-year survival (calculated Kaplan-Meier) was 68% and 63%, respectively. Forty-nine patients (90% of those still alive) answered the GIQLI survey. Median follow-up was 26 months (range, 6-144 months). The mean GIQLI score was 108 (range, 74-138) from a maximum possible value of 144. Our study shows that LA-THE is feasible, safe, and effective in the treatment of adenocarcinoma of the esophagus and GEJ and should probably be considered an alternative to open esophagectomy and other minimally invasive techniques in the treatment of this disease.

Abstract
Achalasia is a primary esophageal motor disorder that results in poor clearance of the esophagus. Although an esophagus filled with debris and undigested food should put these patients at risk for aspiration, the frequency with which the latter occurs has never been documented. In this study, we sought to determine the incidence of respiratory symptoms and complaints in patients with achalasia. A comprehensive symptom questionnaire was administered to 110 patients with achalasia presenting to the Swallowing Center at the University of Washington between 1994 and 2008 as part of their preoperative work-up. Questionnaires were analyzed for the frequency of respiratory complaints in addition to the more typical symptoms of dysphagia, regurgitation, and chest pain. Twenty-two achalasia patients with respiratory symptoms who had also undergone Heller myotomy and completed a post-op follow-up questionnaire were analyzed as a subset. Ninety-five patients (86%) complained of at least daily dysphagia. Fifty-one patients (40%) reported the occurrence of at least one respiratory symptom daily, including cough in 41 patients (37%), aspiration (the sensation of inhaling regurgitated esophagogastric material) in 34 patients (31%), hoarseness in 23 patients (21%), wheezing in 17 patients (15%), shortness of breath in 11 patients (10%), and sore throat in 13 patients (12%). Neither age nor gender differed between those with and those without respiratory symptoms. In the subset of patients with respiratory symptoms who had undergone Heller myotomy, respiratory symptoms improved in the majority after the procedure. Patients with achalasia experience respiratory symptoms with much greater frequency than the approximately 10% that was previously believed. Awareness of this association may be important in the workup and ultimate treatment of patients with this uncommon esophageal disorder.

Does combined multichannel intraluminal esophageal impedance and manometry predict postoperative dysphagia after laparoscopic Nissen fundoplication? Dis Esophagus 2009; 22:656-63.

Abstract
Laparoscopic Nissen fundoplication (LNF) is an effective treatment for gastroesophageal reflux disease; however, some patients develop dysphagia postoperatively. Manometry is used to evaluate disorders of peristalsis, but has not been proven useful to identify which patients may be at risk for postoperative dysphagia. Multichannel intraluminal impedance (MII) evaluates the effective clearance of a swallowed bolus through the esophagus. We hypothesized that MII combined with manometry may detect those patients most at risk of developing dysphagia after LNF. Between March 2003 and January 2007, 74 patients who agreed to participate in this study were prospectively enrolled. All patients completed a preoperative symptom questionnaire, MII/manometry, and 24-h pH monitoring. All patients underwent LNF. Symptom questionnaires were administered postoperatively at a median of 18 months (range: 6-46 months), and we defined dysphagia (both preoperatively and postoperatively) as occurring more than once a month with a severity >or=4 (0-10 Symptom Severity Index). Thirty-two patients (43%) reported preoperative dysphagia, but there was no significant difference in pH monitoring, lower esophageal sphincter pressure/relaxation, peristalsis, liquid or viscous bolus transit (MII), or bolus transit time (MII) between patients with and without preoperative dysphagia. In those patients reporting preoperative dysphagia, the severity of dysphagia improved significantly from 6.8 +/- 2 to 2.6 +/- 3.4 (P < 0.001) after LNF. Thirteen (17%) patients reported dysphagia postoperatively, 10 of whom (75%) reported some degree of preoperative dysphagia. The presence of postoperative dysphagia was significantly more common in patients with preoperative dysphagia (P= 0.01). Patients with postoperative dysphagia had similar lower esophageal sphincter pressure and relaxation, peristalsis, and esophageal clearance to those without dysphagia. Neither MII nor manometry predicts dysphagia in patients with gastroesophageal reflux disease or its occurrence after LNF. The presence of dysphagia preoperatively is the only predictor of dysphagia after LNF.

Abstract
BACKGROUND For a small subset of patients, laparoscopic fundoplication fails, typically resulting in recurrent reflux or severe dysphagia. Although redo fundoplications can be performed laparoscopically, few studies have examined their long-term efficacy. METHODS Using a prospectively maintained database, the authors identified and contacted 41 patients who had undergone redo laparoscopic fundoplications at the University of Washington between 1996 and 2001. The median follow-up period was 50 months (range, 20-95 months). Current symptoms were compared with those acquired and entered into the authors' database preoperatively. Patients also were asked to return for esophageal manometry and pH testing. RESULTS All redo fundoplications were performed laparoscopically. There were no conversions. The most common indication for redo fundoplication was recurrent reflux. The most common anatomic abnormality was a herniated wrap. Heartburn improved in 61%, regurgitation in 69%, and dysphagia in 74% of the patients. Complete resolution of these symptoms was achieved, respectively, in 45%, 41% and 38% of these same patients. Overall, 68% of the patients rated the success of the procedure as either "excellent" or "good," and 78% said they were happy they chose to have it. For those who underwent reoperation for gastroesophageal reflux disease, distal esophageal acid exposure according to 24-h pH monitoring decreased after redo fundoplication from 15.7% +/- 18.1% to 3.4% +/- 3.6% (p = 0.041). CONCLUSION Although not as successful as primary fundoplication, a majority of patients can expect durable improvement in their symptoms with a laparoscopic redo fundoplication.

Long-term outcomes of laparoscopic antireflux surgery for gastroesophageal reflux disease (GERD)-related airway disorder. Surg Endosc 2008; 20:1824-30.

Abstract
UNLABELLED A strong link exists between gastroesophageal reflux disease (GERD) and airway diseases. Surgical therapy has been recommended as it is more effective than medical therapy in the short-term, but there is little data on the effectiveness of surgery long-term. We analyzed the long-term response of GERD-related airway disease after laparoscopic anti-reflux surgery (LARS). METHODS In 2004, we contacted 128 patients with airway symptoms and GERD who underwent laparoscopic antireflux surgery (LARS) between 12/1993 and 12/ 2002. At median follow-up of 53 months (19-110 mo) we studied the effects on symptoms, esophageal acid exposure, and medication use and we analyzed the data to determine predictors of successful resolution of airway symptoms. RESULTS Cough, hoarseness, wheezing, sore throat, and dyspnea improved in 65-75% of patients. Heartburn improved in 91% (105/116) of patients and regurgitation in 92% (90/98). The response rate for airway symptoms was the same in patients with and without heartburn. Almost every patient took proton pump inhibitors (PPIs) preoperatively (99%, 127/128) and 61% (n = 78) were taking double or triple dose. Postoperatively, 33% (n = 45) of patients were using daily antiacid therapy but no one was on double dose. The only factor that predicted a successful surgical outcome was the presence of abnormal reflux in the pharynx as determined by 24-hour pharyngeal pH monitoring. One hundred eleven (87%) patients rated their results as excellent (n = 78, 57%) or good (n = 33, 24%). CONCLUSION LARS provides an effective and durable barrier to reflux, and in so doing improves GERD-related airway symptoms in approximately 70% of patients and improves typical GERD symptoms in approximately 90% of patients. Pharyngeal pH monitoring identifies those patients more likely to benefit from LARS, but better diagnostic tools are needed to improve the response of airway symptoms to that of typical esophageal symptoms.

Long-term outcomes confirm the superior efficacy of extended Heller myotomy with Toupet fundoplication for achalasia. Surg Endosc 2007; 21:713-8.

Abstract
BACKGROUND The standard Heller myotomy (SM) for achalasia extends 1 to 2 cm on to the stomach. The authors perform an extended myotomy (EM) (>3 cm) with the goal of reducing postoperative dysphagia. This study examines the long-term efficacy and durability of EM compared with SM. METHODS Patients with achalasia who underwent a laparoscopic Heller myotomy were identified from a prospective database that includes symptom evaluation and results of esophageal functional studies. From September 1994 to August 1998, the authors performed SM with Dor fundoplication, and from September 1998 through 2003, they performed EM with Toupet fundoplication. In 2001, they performed a telephone survey of all available patients. This was repeated in 2005 for the EM group. The survey included scales of symptom frequency (0 [never], 1 [once per month], 2 [once per week], 3 [once per day], 4 [more than once per day]) and severity (0 [no symptoms] to 10 [symptoms equal to preoperative state]) as well as the need to undergo postoperative intervention for dysphagia. RESULTS For this study, 52 patients underwent SM with Dor fundoplication (median follow-up period, 46 +/- 24 months), and 63 patients underwent EM with Toupet fundoplication (median follow-up period, 45 +/- 17 months. Postoperative dysphagia severity was significantly better in the EM group (4.8 +/- 2.3 vs 3.1 +/- 2.6; p < 0.005). There was no significant difference in postoperative heartburn frequency, esophageal acid exposure, or lower esophageal sphincter pressure. In the SM group, 9 patients (17%) required reintervention for dysphagia: 14 endoscopic interventions for 5 patients (10%) and reoperation for 4 patients. Three patients (5%) in the EM group required reintervention for dysphagia: one endoscopic intervention each and no reoperations (p < 0.05). A total of 30 patients in the EM group were contacted in both 2001 (median follow-up period, 19 +/- 11 months) and 2005 (median follow-up period, 63 +/- 10 months). There was no significant change over time in dysphagia severity (2.6 +/- 1.9 vs 3.7 +/- 2.0; p = 0.19). CONCLUSIONS For the treatment of achalasia, EM with Toupet fundoplication provides excellent durable dysphagia relief that is superior to SM with Dor fundoplication.

Abstract
BACKGROUND Morbid obesity is associated with gastroesophageal reflux disease (GERD), and both have an independent association with motility disorders. Impaired esophageal function is thought to play a role in the development of dysphagia after fundoplication and bariatric procedures (especially restrictive procedures). The authors aimed to define both the physiology and the underlying pathophysiology of swallowing using a novel technique, multichannel intraluminal impedance (MII), which can accurately determine the clearance of a swallowed bolus through the esophagus, in combination with traditional manometry, which can measure peristalsis. METHODS Simultaneous MII, manometry, and pH monitoring were performed for 10 asymptomatic subjects, 22 consecutive nonobese patients with GERD (GERD), and 22 consecutive morbidly obese patients with GERD (MO-GERD) who were under evaluation for antireflux and bariatric surgery at the University of Washington. In this study, MII was defined as abnormal if less than 80% of swallowed liquid boluses cleared the esophagus completely. RESULTS All GERD and MO-GERD patients had abnormal pH monitoring. The manometric findings were similar for the GERD and MO-GERD patients. All the asymptomatic subjects had normal manometry and impedance test results. Abnormal manometry would have predicted that approximately 23% of GERD and MO-GERD patients had defective emptying. However, when measured with impedance, esophageal clearance was found to be defective in two times as many GERD and nearly three times as many MO-GERD patients. CONCLUSIONS In patients with GERD, impedance often detects impairments in esophageal motility not identified by manometry. Morbidly obese patients with GERD have a higher incidence of impaired esophageal motility than nonobese patients with GERD. This may have implications for bariatric procedures, especially those that are restrictive.

Abstract
BACKGROUND Pharyngeal pH monitoring has recently been used to identify patients with extraesophageal symptoms induced by gastroesophageal reflux. We employed this method of acid detection to evaluate patients with respiratory symptoms prior to and after laparoscopic Nissen fundoplication to further elucidate the relationship between GERD and respiratory symptoms. METHODS Twenty-one consecutive patients with extraesophageal symptoms thought to be caused by reflux underwent symptomatic and functional evaluation (esophageal manometry and 24-h pH monitoring with a pharyngeal probe) before and after laparoscopic Nissen fundoplication. Episodes of pharyngeal acid exposure were considered abnormal if the pH dropped below 4, occurred simultaneously with esophageal acidification, and occurred outside meal times. RESULTS All patients had gastroesophageal reflux disease (GERD) and respiratory symptoms; nine of 15 (60%) had evidence of pharyngeal reflux preoperatively. Antireflux procedures resulted in a significant decrease in pharyngeal reflux (7.9 to 1.6 episodes/24h; p <0.05) and esophageal acid exposure (7.5% to 2.1%; p <0.05). In patients with pharyngeal reflux and complete postoperative testing, three (60%) obtained improvement of respiratory symptoms and resolution of pharyngeal reflux. In two patients with recurrent respiratory symptoms after surgery, persistent pharyngeal reflux was detected. CONCLUSION Operative treatment of GERD is effective in controlling extraesophageal reflux, measured subjectively and objectively. Evidence of pharyngeal reflux on pH testing helps to identify which patients with respiratory symptoms will benefit from an antireflux procedure.

Abstract
BACKGROUND Partial fundoplication has traditionally been indicated for patients with gastroesophageal reflux disease (GERD) who have defective peristalsis (DP). Because partial fundoplication had been reported to be a less effective means of controlling acid reflux than total fundoplication, in 1997 we stopped performing partial fundoplication for patients with DP and switched to a floppy total fundoplication. This study analyzes the results of our new strategy and compares it to our former approach. METHODS We performed a partial fundoplication in 39 patients with DP (distal amplitude >40% of swallows) between 1994 and 1997 and a total fundoplication in 57 patients between 1997 and 2000. Symptoms scores derived from a standard questionnaire with a scale of 0-4 manometry, and 24-h pH monitoring were completed preoperatively in 86 patients and postoperatively in 40 patients. RESULTS Heartburn scores improved in both groups (preoperative, 2.8; postoperative, 0.65; p<0.05). Dysphagia was 1.1 preoperatively and 0.62 postoperatively (p=NS) in the partial fundoplication group and 1.2 preoperatively and 0.3 postoperatively (p<0.05) in the total fundoplication group. Furthermore, none of the patients in the total fundoplication group developed new dysphagia and none required dilatation. Distal esophageal acid exposure normalized in both groups after operative treatment (median DeMeester score:72.3 vs 11.3, p<0.05, For partial fundoplication; 57.1 vs 6.3, p<0.05, For total fundoplication). Distal esophageal amplitudes averaged 27.8 mmHg preoperatively and 35.6 mmHg (p = NS) in the partial fundoplication group, they averaged 28.2 mmHg preoperatively vs 49.0 mmHg postoperatively (p<0.005) in the total fundoplication group. Two patients with a previous partial fundoplication required a conversion to a total fundoplication. No postoperative dilation was required in either group. CONCLUSIONS Our study shows that both a partial and a total fundoplication are effective in controlling the symptoms of GERD in patients with defective peristalsis. Dysphagia improves significantly after total fundoplication but not after partial fundoplication. Although both operations brought acid reflux to within normal limits, the effect was more pronounced with total fundoplication. Total, but not partial, fundoplication produced a significant increase in amplitude of esophageal peristalsis, which may explain the subjective improvement during deglutition. Therefore, fundoplication should be the treatment of choice in patients with GERD and defective peristalsis.

Abstract
Surgical treatment of gastroesophageal reflux disease (GERD) is indicated for patients with moderate to severe signs and symptoms or a need for increasing doses of antisecretory drugs. Long segment Barrett's metaplasia is another indication, especially in young patients. Preoperative evaluation differs somewhat depending on whether the patient's symptoms are typical or atypical of GERD. Laparoscopic fundoplication is described. Follow-up of as long as 8 years indicates that more than 90% of patients are satisfied with the results, although 14% are using antisecretory drugs regularly. Recurrent symptoms or dysphagia may indicate surgical failure, and medical therapy, esophageal dilatation, or surgery may be appropriate. Laparoscopic surgery in these patients takes longer than the original procedure but has many benefits if performed by an experienced surgeon.

Abstract
The only treatment currently available for paraesophageal hernia is surgery, which is effective in most cases if the principles of operative therapy are followed. These principles include reducing the stomach, resecting the hernia sac, effectively closing the hiatus, and achieving sufficient gastropexy. The authors believe that a laparoscopic approach to paraesophageal hernias is safe and effective, allowing excellent visualization of the hiatus and superior esophageal mobilization, with significantly less physiologic insult to the debilitated patients in this population. Two questions remain, hoever. First, is an antireflux procedure necessary? The authors believe it is, because of the high rate of postoperative reflux. Additionally, the procedure does not add significant time to the overall operation and provides an excellent anchoring mechanism. Second, is there a higher rate of recurrence with laparoscopic repair? This concern, introduced by Hashemi et al, has not been raised by other authors. The authors have had few recurrences but currently are studying all of their asymptomatic patients for confirmation. For now, the authors consider laparoscopic paraesophageal hernia repair with Nissen fundoplication the procedure of choice for this difficult problem.

Abstract
BACKGROUND Resuscitative measures associated with ruptured abdominal aortic aneurysm (rAAA) repair may result in massive edema of the bowel, retroperitoneum and abdominal wall. The resulting "abdominal compartment syndrome" may compromise abdominal closure and may be associated with respiratory, renal and cardiovascular deterioration. METHODS The medical records of 23 patients surviving initial operative repair of a rAAA were retrospectively reviewed. Eight underwent delayed abdominal closure after early approximation with silastic sheets (n = 6) or of the skin only (n = 2). Ultimate outcome, as well as several pulmonary and cardiovascular parameters, were compared with patients undergoing standard primary fascial closure (n = 15). RESULTS A trend toward improved survival was apparent in the group undergoing delayed abdominal wall closure. Significant improvements in oxygenation and mixed venous oxygen saturation were observed in these patients, and there were fewer late deaths due to multiple organ failure. No patient undergoing delayed abdominal closure developed a graft infection. CONCLUSIONS; As in massively resuscitated trauma victims, delayed laparotomy closure in rAAA patients may confer a physiologic and survival benefit.

Abstract
Hemorrhagic shock appears to predispose patients to subsequent sepsis. This study examined the effect of different resuscitation fluids on macrophage function following hemorrhagic shock. Male Sprague-Dawley rats were bled to a blood pressure of 50 mmHg for 60 min and then resuscitated with 6% hydroxyethyl starch (HES) or Lactated Ringers (LR). Phagocytic function was assessed by clearance of IV colloidal carbon (C). Carbon clearance was not statistically different between control (154.89), shock LR (169.16), and shock HES (144.60). Computerized image analysis of C distribution in sections of liver and spleen taken 4 h after C infusion exhibits a significant decrease in C distribution after resuscitation with HES compared to control and animals resuscitated with LR (Student's t test, p < .05). Male CBA/J mice were bled to a mean blood pressure of 50 mmHg for 60 min and then resuscitated with either LR (N = 18) or HES (N = 17). In separate experiments CBA/J mice had no shock, but were given LR or HES followed by cecal ligation and puncture and later excision (CLPE). A final group had shock with either LR or HES resuscitation and then CLPE as above. Splenocytes were harvested 48 h after shock for mixed lymphocyte culture (MLC). Animals undergoing shock with subsequent septic challenge (Shock/CLPE) showed significantly increased mortality 40 vs. 0% (chi square, p < .05) and immunosuppression on MLC 2,088(LR)/3,300 (HES) vs. 18,570 (LR)/17,705 (HES) compared to CLPE alone (Student's t test, P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)
