Transperitoneal laparoscopic adrenalectomy: outline of the preoperative management, surgical approach, and outcome.

The laparoscopic approach to the adrenal gland has evolved to be the gold standard for most cases of adrenal conditions requiring surgical treatment. There is general consent about the safety, efficacy, and reproducibility of laparoscopic adrenal surgery. Compared to the open surgery, significant advantages with regard to shorter hospitalization time, decreased postoperative morbidity, improved cosmetics, and quicker convalescence are evident. The anatomic location of the adrenal gland led to the development of various approaches, including lateral transperitoneal, anterior transperitoneal, lateral retroperitoneal, posterior retroperitoneal, and even transthoracic approaches. The lateral transperitoneal approach is the technique most frequently used for laparoscopic adrenalectomy. A large operative field provides good orientation and visualization of familiar landmarks known from open surgery. In particular in the early learning curve this represents an advantage of the transperitoneal laparoscopic approach. This article describes in detail the indications, contraindications, preoperative evaluation, surgical technique, management of intraoperative complications, and outcome after lateral transperitoneal adrenalectomy.

Retroperitoneal laparoscopic radical nephrectomy: the Cleveland clinic experience.

PURPOSE: Laparoscopic radical nephrectomy is usually performed by the transperitoneal approach. At our institution the retroperitoneoscopic approach is preferred. We confirm the technical feasibility of retroperitoneoscopic radical nephrectomy, even for large specimens, and compare its results with open surgery in a contemporary cohort. MATERIALS AND METHODS: A total of 47 patients underwent 53 retroperitoneoscopic radical nephrectomies. Data from the most recent 34 laparoscopic cases were retrospectively compared with 34 contemporary cases treated with open radical nephrectomy. RESULTS: For the 53 retroperitoneoscopic radical nephrectomies mean tumor size was 4.6 cm. (range 2 to 12), surgical time was 2.9 hours (range 1.2 to 4.5) and blood loss was 128 cc. Mean specimen weight was 484 gm. (range 52 to 1,328), and concomitant adrenalectomy was performed in 72% of patients. Mean analgesic requirement was 31 mg. morphine sulfate equivalent. Average hospital stay was 1.6 days, with 68% of patients discharged from the hospital within 23 hours of the procedure. Minor complications occurred in 8 patients (17%) and major complications occurred in 2 (4%) who required conversion to open surgery. Various parameters, including patient age, body mass index, American Society of Anesthesiologists status, tumor size (5 versus 6.1 cm.), specimen weight (605 versus 638 gm.) and surgical time (3.1 versus 3.1 hours), were comparable between patients undergoing laparoscopic (34) and open (34) radical nephrectomy. However, laparoscopy resulted in decreased blood loss (p <0.001), hospital stay (p <0.001), analgesic requirements (p <0.001) and convalescence (p = 0.005). Complications occurred in 13% of patients in the laparoscopic group and 24% in the open group. CONCLUSIONS: Retroperitoneoscopy is a reliable, effective and, in our hands, the preferred technique of laparoscopic radical nephrectomy. At our institution retroperitoneoscopy has emerged as an attractive alternative to open radical nephrectomy in patients with T1-T2N0M0 renal tumors.

Laparoscopic nephroureterectomy. A new standard for the surgical management of upper tract transitional cell cancer.

Laparoscopic nephroureterectomy for upper tract TCC still remains somewhat controversial. Unlike laparoscopic radical nephrectomy, which has become widely accepted, LNU is still in its earliest stages. Although there are obvious benefits for the patient who has LNU--less pulmonary complications, less postoperative discomfort, a shorter hospital stay, a better cosmetic result, and a brief convalescence--there are significant concerns. The longer operative time creates a negative financial and professional inducement to learn this technique. Operative times need to fall into the 4-hour range or less to make the procedure cost-effective. Analysis of the efficacy of laparoscopic nephroureterectomy as a curative treatment modality is important. In the short-run, LNU seems to provide similar results to open nephroureterectomy for upper TCC. Although concerns over port site seeding, bladder recurrence, and intraperitoneal seeding have been voiced, these problems have not occurred. The higher incidence of local recurrence noted in the authors' series, however, is of concern and remains an unsettled issue. Despite these local recurrences, the overall cancer survival for a given grade and stage of upper tract TCC seem to be similar to survivals recorded after open nephroureterectomy. Still, the number of LNU cases remains small, and follow-up is brief. These patients need to be monitored closely, with follow-up CT scans over the next decade. The authors believe that there are still several significant hurdles standing in the path of LNU before it can become a widely accepted procedure. Issues of cost, training, and long-term efficacy must be answered definitively. To obtain these types of data, it will be necessary to create a multi-institutional, cooperative study to obtain sufficient numbers of patients with a more than 5-year follow-up on which to base future recommendations.

[Piracetam in anesthesia for prevention of postoperative delirium].

Delirium is a serious postoperative complication after general anaesthesia. The incidence is estimated to be about 10-15%. In the case of additional risk factors, such as old age, previously existing cerebral-vasculous and psychic deficiencies, and anaesthesia of long duration the incidence is much higher. Delirium impairs postoperative mobilisation and convalescence of the patient, can lead to a longer hospital stay and is associated with higher mortality rates. In a series of clinical studies it could be shown that the perioperative administration of the nootropic piracetam led to a shorter recovery period after anaesthesia and had a favourable influence on the delirious symptoms. Especially patients with risk factors for postoperative delirium profited from prophylactic application of piracetam. The success of this medication can be explained by a protective influence of the substance on central neurons against hypoxia, ischemia and intoxication, all of which are discussed as possible causes for postoperative delirium. Next to the pathogenetic mechanisms of postoperative delirium, the mode of action of piracetam is shown in a review and a summary of references on the clinical use in anaesthesia is given.

Kawasaki syndrome and house dust mite exposure.

We investigated exposure to house dust mites and freshly cleaned carpets in patients with Kawasaki syndrome (KS) who resided in Denver, CO. House dust samples were analyzed for mites (Dermatophagoides pteronyssinus and Dermatophagoides farinae) and convalescent sera were assayed for immunoglobulin G antibody to mite antigen. House dust samples from case and neighborhood control homes showed no difference in the prevalence of mites. Fewer than 10% of dust samples from either group revealed evidence of live or dead mites. Nine of 18 (50%) children with KS had a prior history of exposure to freshly cleaned rugs within the 45 days of the onset of KS compared with 3 of 11 (27%) neighborhood controls. There was no difference in mean anti-mite antibody concentrations between convalescent sera from KS cases and sera from pediatric hospitalized controls. We conclude that in Denver KS can occur in the absence of significant mite exposure as defined by environmental studies or serologic means.

Three-year follow-up of a prospective randomized trial comparing laparoscopic versus open gastric bypass.

OBJECTIVE: To analyze long-term weight loss, changes in comorbidities and quality of life, and late complications after laparoscopic and open gastric bypass. SUMMARY BACKGROUND DATA: Early results from our prospective randomized trial comparing the outcome of laparoscopic versus open gastric bypass demonstrated less postoperative pain, shorter length of hospital stay, fewer wound-related complications, and faster convalescence for patients who underwent laparoscopic gastric bypass. METHODS: Between May 1999 and March 2001, 155 morbidly obese patients were enrolled in this prospective trial, in which 79 patients were randomized to laparoscopic gastric bypass and 76 to open gastric bypass. Two patients in the laparoscopic group required conversion to open surgery; their data were analyzed within the laparoscopic group on an intention-to-treat basis. The 2 groups were well matched for body mass index, age, and gender. Outcome evaluation included weight loss, changes in comorbidities and quality of life, and late complications. RESULTS: The mean follow-up was 39+/-8 months. There were no significant differences in the percent of excess body weight loss between the 2 groups at the 3-year follow-up (77% for laparoscopic versus 67% for open). The rate of improvement or resolution of comorbidities was similar between groups. Improvement in quality of life, measured by the Moorehead-Ardelt Quality of Life Questionnaire, was observed in both groups without significant differences between groups. Late complications were similar between groups except for the rate of incisional hernia, which was significantly greater after open gastric bypass (39% versus 5%, P<0.01), and the rate of cholecystectomy, which was greater after laparoscopic gastric bypass (28% versus 5%, P=0.03). CONCLUSIONS: In this randomized trial with a 3-year follow-up, we found that laparoscopic gastric bypass was equally effective as open gastric bypass with respect to weight loss and improvement in comorbidities and quality of life. A major advantage at long-term follow-up for patients who underwent laparoscopic gastric bypass was the reduction in the rate of incisional hernia.

Readiness to recover in adolescent anorexia nervosa: prediction of hospital admission.

OBJECTIVES: To determine if motivation to change in anorexia nervosa during treatment is a predictor of hospitalisation in adolescent patients. METHOD: The Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ), the Eating Disorders Inventory-2 (EDI-2) and the Beck Depression Inventory (BDI) were administered to a group of 70 anorexia nervosa patients (mean age 15.6 years). They were all receiving treatment at a specialised Eating Disorder Unit and were at different points in the treatment programme. Admission during 6-9 month follow-up was recorded in 63 of these patients who had been admitted to the Unit. The other 7 patients were contacted by phone to determine if they had been hospitalised in another unit during the follow-up period. RESULTS: Patients who needed hospital admission during follow-up had higher mean scores at first evaluation on some of the EDI-2 scales and on the BDI, lower ANSOCQ scores and were more likely to have been outpatients at first evaluation. In the logistic regression analysis a low ANSOCQ score and being an outpatient at first evaluation were shown to be independent predictors of hospitalisation during follow-up. CONCLUSIONS: Low motivation to change, depressive symptomatology and some EDI-2 scales are related to the necessity of hospital admission in adolescent patients with anorexia nervosa.

Myopericarditis associated with ECHO virus type 3 infection--A case report.

A case with myopericarditis caused by type 3 ECHO virus was reported. The diagnosis was based on a significantly increased hemagglutination-inhibiting antibody titer (from 4:6 to 4:516) against type 3 ECHO virus in the acute and the convalescent phase. A 29-year-old male was hospitalized for chest pain and fever. The patient had congestive heart failure, pericardial effusion and temporarily appearing abnormal Q waves on his electrocardiogram in the acute phase all of which gradually improved within about 3 weeks. Cardiac catheterization performed on the 21st day of hospitalization disclosed normal coronary arteries, but a partially hypokinetic region was found in the left ventricular free wall. A right ventricular endomyocardial biopsy study revealed histological features of a small number of mononuclear cell infiltrations, myocardial cell necrosis and early fibrosis associated with an increased number of fibroblasts and ultrastructural changes including myocytolysis, vacuolation in sarcoplasm and dissociation of some intercalated discs. The endomyocardial biopsy study, and the electrocardiographic and cineangiographic findings in this case suggest that viral infection may induce clinical signs of myocardial infarction in the heart with normal coronary arteries.

Clipless needlescopic bilateral varix ligation.

We report a novel technique of clipless needlescopic bilateral varix ligation and compare its results with the conventional laparoscopic approach. The positions of ports and surgical procedures were similar to those of the conventional 3-port laparoscopic technique, but all 5- and 10-mm trocars were replaced by 2-mm trocars. The internal spermatic veins proximal to the internal inguinal ring were isolated and coagulated for an adequate segment with a 2-mm bipolar electrocautery apparatus and then transected. The perioperative parameters of 25 patients operated on in this manner were compared with a historical cohort of 25 patients operated on using the conventional laparoscopic approach. Both groups of patients had uneventful surgery with no complications. The mean amount of analgesics used (1.25 vs 3.68 mg of morphine sulfate equivalent, P=.03), the maximal and mean postoperative pain scores (3.5 vs 5.6 and 2.5 vs 4.0, respectively, both P <.05), the postoperative hospital stay (0.5 vs 1.1 days, P=.03), and convalescence to normal activity (0.56 +/- 0.3 vs 1.64 +/- 0.4 weeks, P=.01) were all significantly decreased in the needlescopic group. We conclude that needlescopic bilateral varix ligation not only is feasible and safe but also provides the same therapeutic efficacy of a conventional laparoscopic approach; most importantly, it causes less pain and yields faster convalescence and excellent cosmetic results.

Stapling techniques to facilitate resection of the head of the pancreas.

Thirteen patients underwent duodenocephalopancreatectomy (DCP) with the mechanical staplers to divide the pancreatic neck and to secure haemostasis of the retroportal pancreatic lamina. The stapling techniques used on the pancreas are described. In nine patients with DCP the stapled distal pancreas was anastomosed to the jejunum with Roux-en-Y drainage; one pancreatic complication and no deaths were observed. In four other patients undergoing DCP who were at high risk for severely compromised general conditions, reconstruction of the digestive tract was simplified by leaving the stapled distal pancreas definitively closed: pancreatic complications were recorded in two cases, with no deaths. Mechanical staplers considerably facilitated resection of the neck of the pancreas and of the retroportal pancreatic lamina. All 13 patients who underwent DCP with the use of stapler techniques on the pancreas, including four high-risk patients, were discharged to convalesce on an oral diet after a median postoperative hospital stay of 23 days (range 16-90 days).

Clinical features & prognostic indicators of Japanese encephalitis in children in Lucknow (India).

This communication reports the clinical features of 92 children with Japanese encephalitis diagnosed on the basis of viral isolation from brain or cerebrospinal fluid and/or a 4-fold or higher rise in antibody titre in paired sera by haemagglutination inhibition (HI) test, followed by detection of specific IgM HI antibody. More than a third of the patients (38%) were from urban areas. A high incidence of fever (94.5%), coma (100%) and convulsions (84.7%) was seen. Focal neurological deficit was found in 29.3 per cent of patients and pleocytosis in the cerebrospinal fluid in 32.3 per cent. An extrapyramidal syndrome developed in 21.3 per cent patients during the convalescent stage. Thirty four (36.9%) patients died while in hospital. Mortality was significantly related to a short prodromal stage, deep coma, abnormalities in tone and breathing and decerebrate posturing. Japanese encephalitis represents a severe disease in children with a high early mortality.

Fractures of the femoral neck: a retrospective and prospective study.

Fractures of the femoral neck place increasing demands on orthopaedic resources. A retrospective review of 570 cases compared theatre data with Health Board computer records. Only 333 (58%) were appropriately documented, confirming the unreliability of studies based on hospital-generated data. In a prospective study, 582 patients were followed for 3 months. Of those admitted from home, 64% returned to the community; of those walking without a stick before fracture, 20% remained mobile without support after fracture. Poor mobility before fracture was associated with a higher mortality, but mortality was independent of either fracture type or operative procedure. Acute hospital mortality was low at 3.8% but increased throughout convalescence to 18.7% at 3 months. Continuing audit of this expanding group is necessary as a guide for resource allocation, as well as improving clinical standards and comparing results.

[Level of beta 2-microglobulin in serum of patients with acute viral hepatitis types A, B and C].

Serum beta 2-microglobulin concentrations were assayed in 14 patients with acute hepatitis A, 16 with acute hepatitis B and 10 with hepatitis C. Serum samples were taken from each patient in the first and the second week of hospitalization and in the period of aminotransferase normalization. There was a significant increase of beta 2-microglobulin level in every type of hepatitis compared to the control group. A raised serum beta 2-microglobulin concentration persisted during convalescent period. It decreased gradually in type A and B of hepatitis. Serum beta 2-microglobulin level during convalescence in hepatitis C was similar to that of first weeks of hospitalization.

Subcostal versus transcostal mini donor nephrectomy: is rib resection responsible for pain related donor morbidity.

PURPOSE: Conventional donor nephrectomy is associated with significant postoperative morbidity. Whether this morbidity is associated with rib resection or a long incision is not clear. We designed a prospective randomized study of subcostal and transcostal mini incision donor nephrectomy and compared the results. MATERIALS AND METHODS: We performed 82 donor nephrectomies in the study period of December 2000 to July 2001. Open donor nephrectomies were randomized to subcostal (25) or transcostal (24) mini incision techniques. Results were compared and analyzed using the independent t test. RESULTS: The subcostal and transcostal groups were comparable in terms of patient age, body mass index, nephrectomy side, number of renal vessels and incision length (9.32 vs 9.72 cm). Patients in the subcostal group had a lesser postoperative analgesic requirement (304 +/- 49.8 vs 487 +/- 74.1 mg, p = 0.0001), shorter hospital stay (2.36 +/- 0.7 vs 3.71 +/- 0.81 days, p = 0.0001) and early convalescence (26.56 +/- 4.06 vs 37.46 +/- 6.05 days) compared with the transcostal group. Warm ischemia time and recipient outcome were similar in the groups. CONCLUSIONS: Rib sparing, subcostal mini incision donor nephrectomy has significantly less morbidity and a shorter hospital stay compared with the rib resection transcostal technique.

Immediate tonsillectomy for the treatment of peritonsillar abscess.

Our experience with 119 cases of peritonsillar abscess supports the experience of others, that immediate tonsillectomy is a safe treatment which provides prompt, complete drainage of the abscess. There was one episode of immediate postoperative hemorrhage and one of delayed bleeding, but there were no anesthetic complications. If one believes that the abscess is an indication for tonsillectomy and plans to perform the procedure at some time, we recommend that it be performed as the drainage procedure. The total hospitalization time will as a rule be shortened and a second convalescent period avoided. Its major drawback is the inconvenience of inserting a relative emergency into the schedule.

Hypnoanesthesia for endocrine cervical surgery: a statement of practice.

OBJECTIVES: To assess the feasibility of endocrine cervical surgery under hypnoanesthesia as a valuable, safe, efficient, and economic alternative to general anesthesia. METHODS: Between April 1994 and June 1997, 197 thyroidectomies and 21 cervical explorations for hyperparathyroidism were performed under hypnoanesthesia (HYP) using Erikson's method. Operative data and postoperative course of this initial series were compared to a contemporary population of patients (n = 119) clinically similar except that they declined HYP or were judged unsuitable for it, and who were therefore operated on under general anesthesia (GA). RESULTS: The surgeons all reported better operating conditions for cervicotomy using HYP. Conversion from hypnosis to GA was needed in two cases (1%). All patients having HYP reported a pleasant experience and, keeping in mind that the GA group is not a randomly assigned control group, both had significantly less postoperative pain and analgesic use. Hospital stay was also significantly shorter, providing a substantial reduction in the costs of medical care. The postoperative convalescence was significantly improved after HYP and a full return to social or professional activity was significantly quicker. CONCLUSION: From this study, we conclude that HYP is an effective technique for providing relief of intraoperative and postoperative pain in endocrine cervical surgery. The technique results in high patient satisfaction and better surgical convalescence. This technique can therefore be used in most well-chosen patients and reduces the socioeconomic impact of hospitalization.

Sociologic factors are major determinants of prolonged hospital stay after abdominal aneurysm repair.

BACKGROUND: With increasing pressure to optimize the utilization of hospital resources, it is important to identify patients who may have prolonged hospital length of stay (LOS). The purpose of this report was to identify the preoperative variables that are predictive of prolonged postoperative hospital LOS for patients undergoing elective infrarenal abdominal aneurysm repair and to discuss strategies that might assist in minimizing LOS for these patients. METHODS: Three hundred sixty-five consecutive patients underwent elective infrarenal abdominal aneurysm repair between 1989 and 1994. The relationship between 13 preoperative variables and LOS was analyzed by using both univariate (Kaplan-Meier) and multivariate (Cox regression) statistical techniques. RESULTS: By using Cox regression a model was developed to estimate LOS (p < 0.001 for model). The independent predictors for prolonged LOS were (1) age older than 70 years and (2) absence of a spouse. CONCLUSIONS: Knowledge of the predictive factors that are associated with prolonged LOS should identify those patients who may require prompt and efficient discharge planning, early consultation with a home care nurse, or transfer to a convalescent facility. This approach may significantly improve the utilization of hospital resources.

Borrowed buildings: Canada's temporary hospitals during World War I.

This article explores the alterations and additions made to houses, colleges, and larger public buildings in their temporary use as convalescent homes for wounded Canadian soldiers during World War I. These ''borrowed buildings'' anticipated and emphasized three important characteristics of subsequent hospital architecture by suggesting that domestic environments enhanced healing, that hospitals should be accessible, and that patients should be segregated according to social status and disease. The broader implications of the study are that temporarily appropriated spaces contribute to the definition of many institutions and often act as arenas of resistance to established practices.
