ABSTRACT

BACKGROUND: Oncological outcomes of locally advanced rectal cancer depend on the quality of surgical and oncological management. Enhanced recovery pathways (ERPs) have yet to be assessed for their oncological impact when used in combination with minimally invasive surgery. This study assessed outcomes with or without an ERP in patients with rectal cancer. METHODS: This was a retrospective analysis of all consecutive adult patients who underwent elective minimally invasive surgery for primary rectal adenocarcinoma with curative intent between February 2005 and April 2018. Both laparoscopic and robotic procedures were included. Short-term morbidity and overall survival were compared between patients treated according to the institutional ERP and those who received conventional care. RESULTS: A total of 600 patients underwent minimally invasive surgery, of whom 320 (53·3 per cent) were treated according to the ERP and 280 (46·7 per cent) received conventional care. ERP was associated with less overall morbidity (34·7 versus 54·3 per cent; P < 0·001). Patients in the ERP group had improved overall survival on univariable (91·4 versus 81·7 per cent at 5 years; hazard ratio (HR) 0·53, 95 per cent c.i. 0·28 to 0·99) but not multivariable (HR 0·78, 0·41 to 1·50) analysis. Multivariable analysis revealed age (HR 1·46, 1·17 to 1·82), male sex (HR 1·98, 1·05 to 3·70) and complications (HR 2·23, 1·30 to 3·83) as independent risk factors for compromised overall survival. Disease-free survival was comparable for patients who had ERP or conventional treatment (80·5 versus 84·6 per cent at 5 years respectively; P = 0·272). CONCLUSION: Treatment within an ERP was associated with a lower morbidity risk that may have had a subtle impact on overall but not disease-specific survival.

ABSTRACT

BACKGROUND: The prognostic value of pathological lymph node status following neoadjuvant radiotherapy (ypN) remains unclear. This study was designed to determine whether ypN status predicted overall survival. METHODS: Patients with locally advanced rectal adenocarcinoma who underwent neoadjuvant long-course radiation between 2005 and 2014 were identified from the National Cancer Data Base, and divided into ypN0, ypN1 and ypN2 groups. The primary outcome was overall survival. Univariable and multivariable analyses were used to determine factors associated with overall survival. RESULTS: Of 12 271 patients, 3713 (30·3 per cent) were found to have residual nodal positivity. A majority of patients with ypN1 (1663 of 2562) and ypN2 (878 of 1151) disease had suspected lymph node-positive disease before neoadjuvant therapy, compared with 3959 of 8558 with ypN0 tumours (P < 0·001). Moreover, ypN1 and ypN2 were significantly associated with ypT3-4 disease (65·7 and 83·0 per cent respectively versus 39·4 per cent for ypN0; P < 0·001). In unadjusted analyses, survival differed significantly between ypN groups (P < 0·001). Five-year survival rates were 81·6, 71·3 and 55·0 per cent for patients with ypN0, ypN1 and ypN2 disease respectively. After adjustment for confounding variables, ypN1 and ypN2 remained independently associated with overall survival: hazard ratio (HR) 1·61 (95 per cent c.i. 1·46 to 1·77) and 2·63 (2·34 to 2·95) respectively (P < 0·001). Overall survival was significantly longer in patients with ypN1-2 combined with ypT0-2 status than among those with ypT3-4 tumours even with ypN0 status (P = 0·031). Clinical nodal status before neoadjuvant therapy was not significantly associated with overall survival (HR 1·05, 0·97 to 1·13; P = 0·259). CONCLUSION: Both ypT and ypN status is of prognostic significance following neoadjuvant therapy for rectal cancer.

ABSTRACT

OBJECTIVE: Literature examining the effects of total hip arthroplasty (THA) on subsequent body weight gain is inconclusive. Determining the extent to which clinically relevant weight gain occurs following THA has important public health implications. DESIGN: We used multi-variable logistic regression to compare data from one of the largest US-based THA registries to a population-based control sample from the same geographic region. We also identified factors that increased risk of clinically important weight gain specifically among persons undergoing THA. The outcome measure of interest was weight gain of ≥5% of body weight up to 5 years following surgery. RESULTS: The multi-variable adjusted [age, sex, body mass index (BMI), education, comorbidity and pre-surgical weight change] odds ratio for important weight gain was 1.7 [95% confidence interval (CI), 1.06, 2.6] for a person with THA as compared to the control sample. Additional arthroplasty procedures during the 5-year follow-up further increased odds for important weight gain (OR = 2.0, 95% CI, 1.4, 2.7) relative to the control sample. A patient with THA had increased risk of important post-surgical weight gain of 12% (OR = 1.12, 95% CI, 1.08, 1.16) for every kilogram of pre-operative weight loss. CONCLUSIONS: While findings should be interpreted with caution because of missing follow-up weight data, patients with THA appear to be at increased risk of clinically important weight gain following surgery as compared to peers. Patients less than 60 years and who have lost a substantial amount of weight prior to surgery appear to be at particularly high risk of important post-surgical weight gain.

ABSTRACT

BACKGROUND: Accelerated recovery pathways may reduce length of hospital stay after surgery but there are few data on minimally invasive colorectal operations. METHODS: An enhanced recovery pathway (ERP) was instituted, including preoperative analgesia, limited intravenous fluids and opiates, and early feeding. Intrathecal analgesia was administered as needed, but epidural analgesia was not used. The first 66 patients subjected to the ERP were case-matched by surgeon, procedure and age (within 5 years) with patients treated previously in a fast-track pathway (FTP). Short-term and postoperative outcomes to 30 days were compared. RESULTS: Hospital stay was shorter with the ERP than the FTP: median (interquartile range, i.q.r.) 3 (2-3) versus 3 (3-5) days (P < 0·001). A 2-day hospital stay was achieved in 44 and 8 per cent of patients respectively (P < 0·001). Patients in the ERP had a shorter time to recovery of bowel function: median (i.q.r.) 1 (1-2) versus 2 (2-3) days (P < 0·001). Thirty-day complication rates were similar (32 per cent ERP, 27 per cent FTP; P = 0·570). Readmissions within 30 days were more common with ERP, but the difference was not statistically significant (10 versus 5 patients; P = 0·170). Total hospital stay for those readmitted was shorter in the ERP group (18 versus 23 days). CONCLUSION: ERP decreased the length of hospital stay after minimally invasive colorectal surgery.

ABSTRACT

BACKGROUND: Outcomes for patients with hepatocellular carcinoma (HCC) without cirrhosis and factors associated with disease progression remain unclear. The goals of this single-institution study were to define the outcomes for such patients, and to determine factors associated with survival and disease progression. METHODS: This was a retrospective review of consecutive patients with HCC without cirrhosis who underwent hepatic resection between 1985 and 2003. Survival was estimated by the Kaplan-Meier method and risk factors were identified by Cox proportional hazards models. RESULTS: A total of 143 patients were enrolled, of whom 29·4 per cent had identifiable risk factors for chronic liver disease. Major resection (at least three segments) was undertaken in 63·6 per cent of patients. The operative mortality rate was 3·5 per cent. Median disease-free survival was 2·4 years. Multivariable analysis revealed presence of multiple tumours as the only independent predictor of tumour recurrence. Median overall survival was 3·3 years. Factors independently associated with decreased overall survival were multiple tumours, high histological grade, perioperative transfusion, male sex and age at least 66 years. CONCLUSION: Patients with HCC but without cirrhosis have acceptable outcomes after resection. Specific risk factors for the development of HCC in these patients have yet to be defined.

ABSTRACT

BACKGROUND: There is conflicting data regarding the response to medical and surgical therapy for inflammatory bowel disease with respect to age at disease onset. AIM: To determine if the age at onset of Crohn's disease and ulcerative colitis is a risk factor for surgery for non-neoplastic bowel disease. METHODS: This was a case-control study of patients evaluated between 1998 and 2001. Cases had undergone an initial operation for bowel disease. Controls were matched 1:1 for gender, disease subtype, date of first visit (+/-2 years), time from diagnosis prior to first visit (+/-3 years) and duration of follow-up. Association with age, disease extent, smoking history, medication use and co-morbidities vs. case/control status was assessed using multiple variable conditional logistic regression to estimate the odds ratio (OR) and 95% confidence intervals (CI) for undergoing surgery. RESULTS: Among 132 Crohn's patients, older patients had lower odds for surgery (OR per 5 years, 0.86; 95% CI: 0.75-0.98). The rate of surgery for non-neoplastic bowel disease was not significantly associated with disease distribution, co-morbidities or cigarette smoking. Among 234 ulcerative colitis patients, the rate of surgery was unrelated to age, disease extent, co-morbidities or cigarette smoking, CONCLUSIONS: For Crohn's disease, but not ulcerative colitis, the risk of surgery for non-neoplastic bowel disease decreases with increasing age at diagnosis, irrespective of disease distribution and history of cigarette smoking.

ABSTRACT

BACKGROUND: The incidence rates of gastric and oesophageal adenocarcinoma are changing significantly, but little is known about specific sub-sites. AIM: To use a population-based approach to describe the trends in the site-specific incidence of oesophageal and gastric adenocarcinoma. METHODS: Using the Rochester Epidemiology Project, all cases of gastric and oesophageal adenocarcinoma among Olmsted County, Minnesota, residents first diagnosed between 1971 and 2000 were identified (n = 186). Complete in-patient and out-patient records were reviewed and site determined from pathological, surgical, endoscopic and radiological reports. RESULTS: Between the decades of 1971-1980 and 1991-2000, the incidence of oesophageal adenocarcinoma increased significantly from 0.4 to 2.5 per 100 000 person-years. The incidence of adenocarcinoma of the oesophagogastric junction also increased from a rate of 0.6 to 2.2 per 100 000 person-years. The incidence rate of cancer involving the gastric cardia was stable but the incidence of adenocarcinoma involving distal gastric sites declined. Combined oesophageal and oesophagogastric junction adenocarcinoma (4.7 per 1 000 000 person-years) was as common as gastric adenocarcinoma (3.4 per 100 000 person-years) in 1991-2000. CONCLUSIONS: The incidence rates of adenocarcinoma involving proximal gastric sub-sites do not appear to be increasing in a manner similar to those involving oesophageal sub-sites.

ABSTRACT

Itopride, a dopamine D2 antagonist and acetylcholinesterase inhibitor, significantly improved symptoms in patients with functional dyspepsia in one phase II randomized trial. However, the mechanisms by which itopride may improve symptoms are unknown. We aimed to compare the effects of two doses of itopride and placebo on gastric volumes, gastric emptying, small bowel transit and satiation in female and male healthy volunteers. Randomized, double-blind, placebo-controlled study evaluated gastric function before and after 7 days of itopride 100 mg (n = 16) or 200 mg (n = 15) or placebo (n = 15) t.i.d. Validated methods were used to study gastric accommodation (single photon emission computed tomography), gastric emptying and orocecal transit and satiation postnutrient challenge. The three arms were comparable with regard to age, gender and body mass index. There were no statistically significant effects of itopride on gastric emptying, orocecal transit, fasting gastric volume, maximum tolerated volume or aggregate symptom score with nutrient drink challenge. Postprandial (PP) change in gastric volume differed in the three groups (P = 0.019): 625[+/-28 (SEM)], 555(+/-26) and 512(+/-33) in placebo, itopride 100 and 200 mg groups, respectively. In healthy subjects, itopride reduced total PP gastric volume without accelerating gastric emptying or significantly altering gastric motor and sensory function in healthy individuals.

ABSTRACT

AIMS: The purpose of this study was to determine the lifetime risk of revision surgery for patients undergoing Charnley cemented total hip arthroplasty (THA), with 40-year follow up, using death as a competing risk. MATERIALS AND METHODS: We retrospectively reviewed 2000 cemented Charnley THAs, with 51 living hips available at 40 years. RESULTS: The cumulative risk of revision or removal for any reason was 13% (95% confidence interval (CI) 12 to 15). Patients aged under 50 years at the time of surgery had a 35% (95% CI 28 to 42) risk of revision or removal for any reason (Hazard Ratio (HR) 3.6; 95% CI 2.5 to 5.2; p < 0.001), patients 50 to 59 years old had a 20% risk (95% CI 16 to 24) (HR 2.1; 95% CI 1.5 to 2.8; p < 0.0001), patients aged 60 to 69 years had a 9% risk (95% CI 7 to 11) (reference point), and patients ≥ 70 years old had a 5% risk (95% CI 4 to 7) (HR 0.96; 95% CI 0.6 to 1.5; p = 0.86) during their lifetime. Men had a higher risk of revision or removal for any reason (HR 2.1; 95% CI 1.7 to 2.7; p < 0.001). CONCLUSION: With almost all the patients in this series followed up till either death or revision, we have been able to develop a 'rule of thumb' for lifetime likelihood of revision or implant removal for the Charnley THA: one in three for patients < 50 years, one in five for patients 50 to 59 years, one in ten for patients 60 to 69 years, and one in 20 for patients ≥ 70 years. The results provide a benchmark for comparison of outcomes, for the newer designs of THA. Cite this article: Bone Joint J 2016;98-B:1436-40.

ABSTRACT

The effects of volume of blood, number of consecutive cultures, and incubation time on pathogen recovery were evaluated for 37,568 blood cultures tested with the automated BACTEC 9240 instrument (Becton Dickinson Diagnostic Instrument Systems) at a tertiary care center over the period of 12 June 1996 through 12 October 1997. When the results for this study were compared with previous data published for manual broth-based blood culture systems and patient samples obtained in the 1970s and 1980s, the following were found: (1) the percentage increase in pathogen recovery per milliliter of blood is less, (2) more consecutive blood culture sets over a 24-h period are required to detect bloodstream pathogens, and (3) a shorter duration of incubation is required to diagnose bloodstream infections. Guidelines developed in the 1970s and 1980s for processing and culturing blood may require revision.

ABSTRACT

OBJECTIVE: There is a high prevalence of neurodegenerative disease (parkinsonism, dementia, and motor neuron disease) on the western Pacific island of Guam. We sought evidence in support of the hypothesis that these conditions are triggered by nutritional deficiencies of calcium and magnesium leading to secondary hyperparathyroidism that then facilitates the entry of calcium and toxic heavy metals into the brain. METHODS: We analyzed indices of calcium metabolism plus blood-serum, urine, nail, and hair heavy metal concentrations in 12 patients with Guamanian neurodegenerative disease and 12 Chamorro control subjects. RESULTS: All 12 patients with Guamanian neurodegenerative disease had normal values for serum total and ionized calcium, 25-hydroxyvitamin D, and 24-hour urine collections for calcium. Eleven of 12 patients had normal serum parathyroid hormone values and alkaline phosphatase levels. No patient had reduced serum phosphorus or magnesium values although a minority of patients and controls had low urinary magnesium concentrations. Median blood-serum and 24-hour urine collections for heavy metals (aluminum, arsenic, cadmium, copper, iron, lead, manganese, mercury, and zinc) were statistically similar in the patient and control groups except for a slight elevation of blood, but not urine, lead in the patient group. Concentrations of heavy metals in hair and nails were similar in the two groups. CONCLUSIONS: We could find no evidence in support of abnormalities of calcium metabolism or heavy metal absorption as a major causative factor in the development of neurodegenerative disease on the island of Guam.

ABSTRACT

BACKGROUND: Invasive fungal infection has a major impact on the morbidity and mortality of liver transplant recipients. Human herpesvirus (HHV)-6 infection after transplantation is associated with an immunosuppressive state and the development of cytomegalovirus disease. Because cytomegalovirus infection is a risk factor for invasive fungal infection after transplantation, we have examined whether HHV-6 and fungal infection are associated after transplantation. METHODS: Pretransplantation sera from 247 consecutive liver transplant recipients were analyzed for IgG to HHV-6. Thirty-three (13%) HHV-6-seronegative recipients were identified. Six of 33 (18%) seronegative recipients experienced fungal infection as compared with 15 of 214 (7%) seropositive recipients (P=0.034). RESULTS: In a univariate analysis of risk factors for fungal infection, pretransplantation seronegativity to HHV-6 (P=0.034), intraoperative cryoprecipitate requirements greater than the 75th percentile (P=0.035), reoperation (P=0.005), biliary stricturing postoperatively (P=0.046), and gastrointestinal or vascular complications postoperatively (P=0.030) were identified as significant risk factors. Moreover, in pairwise multivariate analysis, pretransplantation HHV-6 seronegativity remained a significant variable even in the presence of each of the other variables. CONCLUSIONS: These results suggest that HHV-6 seronegativity before transplantation is a valuable clinical marker that identifies patients at risk for developing fungal infection after transplantation.

ABSTRACT

Fungal infections are associated with a high mortality rate after liver transplantation. To describe risk factors for fungal infections, 405 consecutive liver transplant recipients were analyzed. Forty-five patients (11%) developed invasive fungal infection. Median posttransplantation time to the first episode was 60 days. Pathogens were Candida species (spp) (n=24, 53%), Cryptococcus neoformans (n=10, 22%), Aspergillus spp (n=6, 13%), Rhizopus spp (n=l), and others (n=4). Presentations of infection included disseminated (n=9), intra-abdominal (n=9), esophageal (n=9), lung (n=8), blood (n=6), and central nervous system infections (n=3), and sinusitis with esophagitis (n=1). Eighteen patients (40%) with invasive fungal infection died, and 13 (72%) of these deaths were attributable to fungi. Mortality in the nonfungal infection group was 12%. Univariate analysis identified separate risk factors for Candida (intra-abdominal bleeding), Aspergillus (fulminant hepatitis), and cryptococcal (symptomatic cytomegalovirus infection) infections. In both univariate and multivariate analyses, a high intratransplant transfusion requirement and posttransplant bacterial infection were identified as significant risk factors for all types of fungal infection. The risk factor analysis reported here suggests that different pathogenic processes lead to Candida and non-Candida infection in liver transplant recipients. Their identification should prompt specific prophylactic measures to reduce morbidity and mortality in this population.

ABSTRACT

To analyze the clinical characteristics of and identify specific risk factors for enterococcal bacteremia following liver transplantation, we performed a study in 405 consecutive liver transplantation recipients prophylaxed with a selective bowel decontamination regimen. Seventy enterococcal bacteremias in 52 patients were identified. Enterococcus faecalis (50) outnumbered Enterococcus faecium isolates (18), and 49% of enterococcal bacteremias were polymicrobial. Biliary tree complications were present in 34% of enterococcal bacteremias. Of the 15 deaths (29%) among the patients with enterococcal bacteremia, 4 were directly associated with enterococcal bacteremia. In a multivariate analysis, Roux-en-Y choledochojejunostomy (P=0.005), a cytomegalovirus-seropositive donor (P=0.013), prolonged transplantation time (P=0.02), and biliary stricturing (P=0.016) were identified as significant risk factors. Other risk factors identified in a univariate analysis included primary sclerosing cholangitis (P=0.009) and symptomatic cytomegalovirus infection (P=0.008). Enterococcal bacteremia is a frequent infectious complication in liver transplantation recipients receiving selective bowel decontamination. Its association with cytomegalovirus and biliary tree abnormalities suggest specific areas for prophylactic intervention.

ABSTRACT

BACKGROUND: The sensitivity of assays for antineutrophil cytoplasmic antibody (ANCA), anti-Saccharomyces cerevisiae antibody (ASCA), and antipancreatic antibody (PAB) in different laboratories is unknown. Likewise, the sensitivity and diagnostic usefulness of these assays in patients with inflammatory bowel disease (IBD) in the community is unknown. METHODS: An incidence cohort of 290 patients with IBD were offered participation in the study. Blood was obtained from 162 patients (56%) (83 with ulcerative colitis, 79 with Crohn's disease) who agreed to participate. ANCA was determined in five laboratories. ASCA in two laboratories, and PAB in one laboratory. RESULTS: In ulcerative colitis, the sensitivity of ANCA determined in five laboratories varied widely, ranging from 0-63%. In Crohn's disease, the sensitivity of ASCA determined in two laboratories did not vary significantly, ranging from 39-44%; and the sensitivity of PAB determined in one laboratory was 15%. The optimal diagnostic usefulness was obtained from one laboratory where the positive predictive values of a positive ANCA assay combined with a negative ASCA assay for ulcerative colitis, and a negative ANCA combined with a positive ASCA for Crohn's disease, were 75% and 86%, respectively. CONCLUSIONS: In patients with IBD, the sensitivity of ANCA varied widely in different laboratories, whereas the prevalence of ASCA was similar. The positive predictive values of the ANCA assay combined with the ASCA assay for ulcerative colitis and Crohn's disease are high enough to be clinically useful.

ABSTRACT

OBJECTIVE: To clarify the true benefits of laparoscopic-assisted colectomy by comparing clinical outcomes from a series of laparoscopic right colectomies with matched open colectomies, all performed for the singular indication of polyp not amenable to colonoscopic removal. PATIENTS AND METHODS: A retrospective case-matched study was performed of consecutive patients undergoing laparoscopic-assisted right hemicolectomy for polyps between January 1992 and July 1997. Each case was matched to a control undergoing the equivalent open procedure for the same indication during the same time period. RESULTS: Thirty-eight patients undergoing laparoscopic-assisted right hemicolectomy for polyps were identified, and matches were found. The conversion rate was 18.4% (7/38), 21.4% early in the series and 10% in later experience. Operative times were longer for laparoscopic-associated colectomy (median, 208 minutes vs 150 minutes, P < .001). Laparoscopic-assisted colectomy resulted in shorter postoperative ileus (time to flatus, 3.0 vs 4.0 days, P < .001; time to bowel movement, 3.5 vs 5.0 days, P < .001) and in earlier tolerance of regular diet (3.5 vs 6.0 days, P < .001). Fewer days of narcotic administration were required by the laparoscopic group (3.0 vs 4.5 days, P < .001). This resulted in a significantly shorter length of hospital stay (4.0 vs 7.0 days, P < .001). There was no significant difference in the incidence of postoperative complications. CONCLUSIONS: Laparoscopic right hemicolectomy has significant patient benefits. These benefits are apparent when procedures of equal complexity and equivalent indications are compared. Laparoscopic-assisted resection has become our preferred approach for polyps not amenable to colonoscopic polypectomy.

ABSTRACT

OBJECTIVE: To describe the clinical course, survival, resource use, and direct medical costs of care for patients with high-grade astrocytomas. MATERIAL AND METHODS: All patients with grade 3 or 4 astrocytoma who resided in Olmsted County, Minnesota, or one of the six adjacent counties and had a tissue diagnosis first made between 1987 and 1992 were studied. Clinical characteristics, initial management, use of resources, clinical course, survival, and medical charges were analyzed. RESULTS: Sixty-four patients, with a mean age of 62 years, were identified; 81% had glioblastoma multiforme. Approximately 60% underwent surgical resection, 80% had radiotherapy, and 50% had chemotherapy for initial management. After initial treatment (median duration, 116 days), approximately 75% of patients had a course with stable disease (median duration, 198 days). The overall median duration of survival was 323 days; lower grade and younger age were significantly associated with longer median survival-for example, 1,493 days for patients younger than 65 years with grade 3 astrocytomas and 205 days for patients 65 years old or older with grade 4 astrocytomas. The mean total direct medical charges were $67,887. CONCLUSION: In most patients with high-grade astrocytomas, a substantial period elapsed before disease progressed. Although the overall median duration of survival was less than 1 year, younger patients, especially those with grade 3 astrocytomas, had a longer survival. The management of patients with high-grade astrocytomas uses substantial health-care resources.

ABSTRACT

OBJECTIVE: To document and examine the concerns patients have prior to undergoing primary total hip or total knee arthroplasty in a tertiary care center or an orthopedic private practice group. PATIENTS AND METHODS: In this prospective survey, 136 patients from a tertiary care center and 130 from an orthopedic private practice group completed a questionnaire covering 54 items regarding their concerns prior to undergoing primary total hip or total knee arthroplasty. Patients responded on a visual analog scale, and concern was ranked by mean responses (1, not concerned at all; 2, somewhat concerned; 3, very concerned; or 4, extremely concerned). RESULTS: Responses to only 6 items averaged scores higher than 1.9: pain immediately after the surgery (2.07), length of recovery (2.07), ability to walk as much as you wish (2.03), ability to return to recreational activities (1.97), ability to go up and down stairs (1.94), and risk of getting acquired immunodeficiency syndrome from a transfusion (1.92). Older patients (> or = 65 years) were less concerned than younger patients (< 65 years) in 34 of the 54 questions asked. Women were more concerned than men in 19 of the 54 questions asked. CONCLUSION: These data provide information that will be helpful in preoperative patient discussions and in development of educational materials for patients undergoing total hip or total knee arthroplasty.

ABSTRACT

OBJECTIVE: To determine whether the severity of maternal injury or other maternal and fetal variables will predict the outcome of pregnancy in the injured pregnant patient. PATIENTS AND METHODS: In this retrospective review of pregnant patients hospitalized at a level 1 trauma center from 1986 to 1996, we analyzed the maternal Injury Severity Score, maternal mortality, fetal-neonatal mortality, maternal hypotension, and fetal heart rate. RESULTS: Sixty-one pregnant women were identified who were hospitalized after trauma. The mean +/- SD maternal age was 26.6 +/- 6.6 years. The distribution of trauma per gestational age was 21%, 20%, and 59% for the first, second, and third trimester, respectively. The most common mechanism of injury was motor vehicle crashes. Long-term pregnancy outcome was available in 53 patients (87%). There was 1 maternal death. Fetal-neonatal death occurred in 8 (15%) of 53 pregnancies. Most maternal physiologic variables were not predictors of pregnancy outcome. We were unable to detect a difference in the distribution of Injury Severity Scores between viable and nonviable pregnancies. However, maternal hypotension and low fetal heart rate were common in nonviable pregnancies (P = .02). CONCLUSIONS: Maternal hypotension and fetal heart rate are potential predictors of pregnancy outcome after trauma. Other maternal and fetal physiologic variables are poor measures of fetal well-being and are unable to predict fetal outcome. Fetal-neonatal death does not necessarily correlate with severity of maternal injury.

ABSTRACT

OBJECTIVE: To evaluate our initial experience with laparoscopic inguinal herniorrhaphy. DESIGN: We retrospectively studied a consecutive series of patients selectively chosen for laparoscopic repair of inguinal hernia. MATERIAL AND METHODS: The study cohort consisted of 173 patients treated by a single surgeon between 1992 and 1995. For all operations, a transabdominal approach was used. Follow-up was obtained by telephone contact or letter. RESULTS: The study group consisted of 167 male and 6 female patients with a mean age at operation of 55 years (range, 15 to 81). During the study period, 206 laparoscopic inguinal hernia repairs were performed in the 173 patients. Only one patient (0.6%) required conversion to laparotomy. Bilateral hernia repair was done in 31 patients (18%). Of the 206 procedures, 63 repairs (31%) were performed for recurrent hernias. In 69% of the patients, the procedure was completed on an outpatient basis. Early postoperative complications necessitating surgical intervention occurred in four patients. The median time to return to work or normal physical activity was 7 days for unilateral and 12 days for bilateral hernia repair (P = 0.18). A mean follow-up of 29 months was obtained for 171 patients (99%). In six patients (3%), a recurrent hernia developed. Four of these six patients had previously undergone an open surgical procedure on the side of the recurrence. CONCLUSION: Laparoscopic inguinal herniorrhaphy is a feasible alternative to open hernia repair. This operation, however, should be reserved for selected patients. Longer follow-up and controlled trials comparing laparoscopic and tension-free open herniorrhaphy are necessary for assessment of the relative benefits of this procedure.
