Single-session laparoscopic radical and contralateral partial nephrectomy.

Renal tumor is likely to become one of the most important indications for laparoscopic surgery. We present an old woman, who underwent single-session laparoscopic nephrectomy and contralateral partial nephrectomy due to bilateral kidney tumor. The advantages of simultaneous bilateral intervention are reduced psychological stress, single anaesthesia, less medication, less blood loss, shorter hospital stay and convalescence, and considerable cost-effectiveness.

Laparoscopic nephrectomy in young-old, old-old, and oldest-old adults.

BACKGROUND: This study reports findings for laparoscopic nephrectomy in comparison with open nephrectomy in geriatric patients. METHODS: Since 1993, a total of 249 patients have undergone nephrectomy for benign disease at the Medical University of Lübeck, Germany. In 11 patients older than 65 years, a laparoscopic nephrectomy was performed (in the majority via a transperitoneal approach), and 42 patients older than 65 years underwent an open-flank nephrectomy. Clinical parameters were evaluated in comparison with both groups and stratified according to age groups. RESULTS: With respect to operative results (operative duration and pre- and postoperative hemoglobin levels), no relevant differences were observed between the laparoscopy group and the open-nephrectomy group, even when stratified according to patient age. However, patients in the laparoscopy group demonstrated a significant advantage concerning blood loss and the number of required blood transfusions, regardless of age. In addition, patients after laparoscopy showed advantages in the postoperative course. Benefits were proven for the analgesic consumption, hospital stay, and convalescence parameters. Although complication rates were comparable in both groups, an increase was observed in both groups for patients aged between 75 and 84 years. CONCLUSIONS: Laparoscopic nephrectomy offers comparable operative results (with reduced blood loss and less need for blood transfusions) when compared with open surgery. Significant advantages can be demonstrated in the postoperative course, and especially geriatric patients benefit from these aspects of the minimally invasive approach. Laparoscopy should be regarded as the primary therapeutic option for nephrectomy for benign disease in these patients.

Laparoscopic management of ectopic pregnancy in a resident training program.

The range of procedures now routinely done through the laparoscope has continued to expand due to improved equipment for insufflation, hemostasis, and tissue manipulation, and to imaginative approaches to otherwise "routine" gynecologic problems traditionally treated by laparotomy. As with all new technologies, advocates predict that the methodology will prove to have an almost unlimited potential, while established skeptics predict that it will have a narrow applicability. With time and further clinical application, a consensus somewhere between the two positions will be reached. But while this technology develops and experience begins to accumulate, it is necessary to train residents in the technique. We discuss our experience with introducing laparoscopic management of ectopic pregnancy into a residency training program. Our results indicate a rapid learning curve, with minimal patient morbidity, brief hospitalization, and rapid convalescence.

Internal pancreatic fistulas: proposal of a management algorithm based on a case series analysis.

BACKGROUND AND AIMS: Internal pancreatic fistulas (IPF) are an uncommon but well-recognized complication of chronic pancreatitis (CP) that are associated with significant morbidity and mortality. Because of their low incidence, management is still controversial. The aims of this study are to report the 8-year experience with IPF management in a Brazil University-affiliated hospital and to propose a management algorithm. STUDY: A centralized diagnostic index was used to retrospectively identify all patients with IPF admitted to a teaching hospital from 1995 to 2003. The patient's medical records were reviewed for clinical features, diagnostic work-up, treatment strategies, response to therapy, and the length of hospital stay. All patients underwent contrast-enhanced computed tomography of the abdomen and endoscopic retrograde cholangiopancreatography, to guide the therapeutic modality to be offered. Conservative therapy included withholding of oral feedings in conjunction with total parenteral nutrition, octreotide subcutaneously, and multiple paracentesis or thoracentesis. Interventional therapy was either endoscopic or surgical. RESULTS: IPF was identified in 11 (7.3%) of 150 patients with CP. They ranged in age from 24 to 47 years (mean 36.1), with a male to female ratio of 10:1. All patients had underlying alcoholic CP. The presentation was pancreatic ascites in 9 patients and pleural effusion in 2 cases. Five patients were undergoing the conservative treatment, all presenting main pancreatic duct (MPD) dilatation; endoscopic placement of transpapillary pancreatic duct stent was performed in 4 patients who presented partial MPD stricture or disruption; surgical therapy was performed in 2 patients exhibiting complete MPD obstruction or disruption. Stents were removed 3 to 6 weeks after initial placement. IPF resolved in 10 of 11 patients (90.9%) within 6 weeks. The resolution of IPF was faster (13 +/- 5 vs. 25 +/- 13 days, P < 0.01) and the length of hospital stay was significantly shorter (17.2 +/- 5.6 vs. 31.2 +/- 4.4 days, P < 0.01) in patients subject to interventional treatment compared with those treated conservatively. There was 1 death due to sepsis in a patient managed conservatively; no death was recorded in the interventional therapy group. There was no recurrence of IPF at a mean follow-up of 38 months. CONCLUSIONS: Our results suggest that interventional therapy should be considered the best approach for the management of IPF in patients presenting MPD disruption or obstruction. Conservative therapy must be reserved for those showing MPD dilatation without ductal disruption or stricture. Early interventional therapy reduced hospital stay and convalescence, which likely resulted in lower healthcare overall costs.

Retroperitoneoscopic pre-transplant native kidney nephrectomy.

AIMS: Laparoscopic nephrectomy has become a standardized procedure for removal of benign non-functioning kidneys. We present our experience of retroperitoneoscopic pre-transplant native kidneys nephrectomy. METHODS: Comparison of 40 patients who underwent retroperitoneoscopy with 40 open simple pre-transplant nephrectomy patients was done. RESULTS: Forty retroperitoneoscopic nephrectomies were done between June 2003 and April 2005. The mean operative time was similar in the two groups; however, the mean blood loss, postoperative analgesic requirement, complication rate, hospital stay and convalescence period were significantly less in the retroperitoneoscopic group. CONCLUSION: Retroperitoneoscopic nephrectomy should be offered as the primary treatment modality to patients requiring pre-transplant native kidney nephrectomy, except in patients where it is contraindicated.

Laparoscopic nephrectomy: Mansoura experience with 106 cases.

OBJECTIVE: To describe the technique and report our experience of laparoscopic nephrectomy. PATIENTS AND METHODS: Between August 1992 and December 1993, 106 patients underwent laparoscopic nephrectomy at the Mansoura Urology and Nephrology Center. RESULTS: Of the 106 patients, laparoscopic nephrectomy was performed successfully in 97 cases. Conversion to an open procedure was necessary in the remaining nine patients. CONCLUSION: For a selected group of patients, laparoscopic nephrectomy is a feasible and safe technique. The length of hospital stay and convalescence is short and return to work is rapid.

Simultaneous bilateral percutaneous nephrolithotomy in children.

UNLABELLED: In the paediatric section, two papers relating to the upper urinary tract are presented. The first, from Hungary, describes simultaneous bilateral percutaneous nephrolithotomy in 13 patients, where it was deemed feasible; this is the first such report. Authors from London report on unilateral nephrectomy in patients with nephrogenic hypertension, and found that it was successful in normalising blood pressure in patients with renal hypertension with a normal contralateral kidney. OBJECTIVE: To evaluate the efficacy of removing bilateral kidney stones simultaneously from children, in one session. PATIENTS AND METHODS: Thirteen patients (three girls and 10 boys, 26 kidneys; mean age 8 years, range 3-14) underwent simultaneous bilateral percutaneous nephrolithotomy (PCNL) in the same session, under general anaesthesia, starting with ureteric catheter insertion into both kidneys and using a 26 F adult nephroscope. The mean (range) stone diameter was 2 (1-3.5) cm. Three patients had staghorn stones in one of their kidneys. Ultrasonic disintegration was used; two patients had bilateral and two others unilateral endopylotomy, and one patient had percutaneous suprapubic cystolithotomy in the same session. The mean (range) operative duration was 65 (55-90) min. RESULTS: All patients were rendered stone-free; there was no severe bleeding or any other complication. On one side in one of the patients, a second session was needed because of residual stone. The nephrostomy tubes were removed 3 and 4 days after PCNL and the hospital stay was 6 (1-11) days. CONCLUSION: The advantages of simultaneous bilateral PCNL are reduced psychological stress, one cystoscopy and anaesthesia, less medication and a shorter hospital stay and convalescence, with considerable savings in cost. In experienced hands this method can be used not only in adults but also in children. To our knowledge this is the only report of this technique in children.

Institutions in modern society: caretakers and subjects.

The problems that relate to the outermost limits of institutional care, if such limits exist, will certainly be among the most salient problems during the coming years-no matter whether such care proceeds on an inpatient or an outpatient basis. Whatever course may be taken will certainly affect the lives of every citizen in urbanized and industrialized society. At present in California there is considerable shifting of individuals from one care status or category to another, in efforts to find accommodations that will better reflect the realities of modern existence. However, such shifting of caseloads as the moving of individuals from nursing and convalescent homes to hospitals and back again does not constitute a change, either from the standpoint of the subjects involved or from the standpoint of significantly affecting the overall caseload. Most commonly, the shifting of caseloads has been merely jurisdictional. Much the same can be said of the transfers from a police agency to welfare, or vice versa. Similarly, a shift from inpatient status to outpatient status does not constitute a significant change. Such transfers from one jurisdiction to another reflect a reduction in caseload for one agency, but a corresponding increase in caseload for another. Thus, there has been no significant change in the subject population as such. Jurisdictional transfers are often merely caretaking actions that reflect bureaucratic decisions. Equally often, such decisions do not address themselves to the basic priorities that guide the functions of caretaking. Explicitly stated priorities must supersede jurisditional transfers if the concept of caretaking is to include better resources for human development and if the subject population is to participate in the managing of institutions. On any given day during 1969 in the state of California, virtually 8 million people from an estimated population of 19,800,000 were under some form of institutional care or in some institutional program, or were employed to provide the care and administer the programs. Clearly this is a vast effort toward the training and retraining, as well as the rehabilitation of people, in the traditional sense of these words. The salient problems that have emerged from this context of urban and industrial development involve social control, social mobility, organizational behavior by caretakers and subjects, minority peoples, and the extensions of institutions into communities. Given these developments, is it not proper to ask whether or not the nature of urbanized and industrialized society has changed to such a point that a return to the past (and past solutions) is no longer feasible? Is it not also proper to ask what voice the subject population will have in helping to guide the urban and industrialized state into the future? And certainly there is a question that virtually everyone will ask: What percentage of tax revenues (whether shared or under direct programs) shall be destined to better meet the problems of this future society, which, it seems, is already upon us?

Pasteurella pneumonia: report of a case and review of the literature.

A case of pneumonia due to Pasturella ureae was encountered in a 57-year-old man who developed bilateral pulmonary infiltrates and respiratory insufficiency while convalescing in the hospital from a hip fracture and multiple rib fractures. Cultures of his sputum grew an essentially pure growth of Pasturella ureae. This organism, a small gram-negative rod, could be differentiated from the other Pasteurella species by its ability to hydrolyze urea and failure to produce indole. The literature on Pasteurella infections is briefly reviewed, and the recent taxonomic revisions of the genus Pasteurella are discussed.

Laparoscopic radical nephrectomy.

Laparoscopic radical nephrectomy has gained in popularity as an accepted treatment modality for localized renal cell carcinoma at many centers worldwide. Laparoscopic radical nephrectomy may be performed via a transperitoneal or retroperitoneal approach. Mostly, the transperitoneal approach is used. Current indications for laparoscopic radical nephrectomy include patients with T(1)-T(3a)N(0)M(0) renal tumors. Herein, transperitoneal as well as retroperitoneal laparoscopic approaches are described. Surgical outcomes and complications from published series are reviewed with comparison to open surgery. Special related concerns as oncologic principles, organ retrieval, lymphadenectomy, and concomitant adrenalectomy are addressed. In conclusion, laparoscopic radical nephrectomy is now established with considerable advantages; decreased postoperative morbidity, decreased analgesic requirements, improved cosmesis, shorter hospital stay and convalescence. Although no long-term follow-up is available, short and intermediate follow-up results confirm the effectiveness of laparoscopic radical nephrectomy.

Hand-assisted laparoscopic nephrectomy as a minimally invasive option in the treatment of large renal specimens.

INTRODUCTION: We describe our experience with hand-assisted laparoscopy (HAL) as an option for the treatment of large renal specimens. MATERIALS AND METHODS: Between March 2000 and August 2004, 13 patients candidate to nephrectomies due to benign renal conditions with kidneys larger than 20 cm were included in a prospective protocol. Unilateral nephrectomy was performed in cases of hydronephrosis (6 patients) or giant pyonephrosis (4 patients). Bilateral nephrectomy was performed in 3 patients with adult polycystic kidney disease (APKD) with low back pain refractory to clinical treatment previous to kidney transplant. The technique included the introduction of 2 to 3 10 mm ports, manual incision to allow enough space for the surgeon's wrist without a commercial device to keep the pneumoperitoneum. The kidney was empty, preferably extracorporeally, enough to be removed through manual incision. We have assessed operative times, transfusions, complications, conversions, hospital stay and convalescence. RESULTS: The patients mean age (9 women and 4 men) was 58 years. Mean operating time was 120 +/- 10 min (hydronephrosis), 160 +/- 28 min (pyonephrosis) and 190 +/- 13 min (bilateral surgery for APKD). There was a need for a conversion in 1 case and another patient needed a transfusion due to a lesion in the renal vein; 2 patients had minor complications. CONCLUSIONS: HAL surgery is a minimally invasive alternative in the treatment of large renal specimens, with or without significant inflammation.

A 10-year follow-up study of tick-borne encephalitis in the Stockholm area and a review of the literature: need for a vaccination strategy.

143 people treated for tick-borne encephalitis (TBE) were included in a retrospective follow-up study. Sequelae and epidemiological characteristics in 114 individuals were analysed. The case fatality rate and the prevalence of residual paresis were low, 1.4 and 2.7%, respectively. However, 40 (35.7%) individuals were found to have a postencephalitic syndrome after a median follow-up time of 47 months, and a majority (77.5%) of these were classified as moderate to severe. Various mental disorders, balance and co-ordination disorders and headache were the most frequently reported symptoms. Increasing age was correlated to a longer duration of hospital stay, longer convalescence and increased risk of permanent sequelae. Results from a neuropsychiatric questionnaire showed marked differences between the subjects with sequelae compared to controls. 57% had noticed a tick bite before admission, and 48% were aware of at least one person in their environment who previously had contracted TBE. 79% were permanent residents or visited endemic areas often and regularly. In conclusion, we have found that TBE in the Stockholm area has a low case fatality rate, but gives rise to a considerable number of different neurological and mental sequelae, which justifies vaccination of a defined risk population in endemic areas.

New techniques for the treatment and disruption of renal calculi.

Kidney stones are a major cause of morbidity and affect 3 to 4% of Western Europeans. Two new techniques have been developed in the last five years which reduce the morbidity, hospital stay and convalescent period of patients compared with those undergoing conventional renal surgery. These methods, percutaneous nephrolithotomy and extracorporeal stone disintegration, are examined with particular reference to the equipment necessary for stone disintegration. There is little doubt that these techniques will supersede conventional surgical procedures in the near future.

Advancing conservative treatment of ectopic pregnancy--laparoscopic and "non-surgical" management.

Improvements in diagnostic measures have contributed to the earlier diagnosis of ectopic pregnancy which in turn has led to the development of new and alternative methods of managing tubal pregnancies. Laparoscopic salpingotomy offers advantages such as a reduction in operating time and shorter hospital stays and convalescence as compared with conventional abdominal surgery. Furthermore, neither the frequency of persistent trophoblasts nor of second operations is increased, and the subsequent fertility rate is at least equal to that after laparotomy. "Non-surgical" treatment of ectopic pregnancy, such as systemic administration of methotrexate and laparoscopic/transvaginal ultrasonic--guided local injection of methotrexate, prostaglandins or hyperosmolar glucose, are attractive alternative methods in selected cases. These methods are safe and effective and have a high success rate and promising results for fertility. Laparoscopy is preferred to conventional abdominal surgery for the treatment of ectopic pregnancy. In selected cases, "non-surgical" treatment can be an attractive alternative therapy.

Controversies in the treatment of gastroesophageal reflux and achalasia.

The immense success of laparoscopic surgery as an effective treatment of gastroesophageal reflux disease (GERD) and achalasia has established minimal invasive surgery as the gold standard for these two conditions with lower morbidity and mortality, shorter hospital stay, faster convalescence, and less postoperative pain. One controversy in the treatment of GERD evolves around laparoscopic antireflux surgery (LARS) as the preferred treatment for Barrett's esophagus and the procedure's potential to reduce the risk of adenocarcinoma of the esophagus. GERD has also been associated with respiratory symptoms, asthma and laryngeal injury, and a second controversy prompts discussions about whether total or partial fundoplication is the more appropriate treatment for GERD. A new and promising alternative in the treatment of GERD is endoluminal therapy. Three types of this new treatment option will be discussed: radiofrequency energy delivered to the lower esophageal sphincter, the creation of a mechanical barrier at the gastroesophageal junction, and the direct endoscopic tightening of the lower esophageal sphincter. Laparoscopic surgery is discussed not only as a very effective treatment for GERD but also as permanent cure for achalasia. This review analyzes the three most important treatment options for achalasia: medications, pneumatic dilatation, and surgical therapy. Medications as the only true non-invasive option in the treatment of achalasia are not as effective as LARS because of their short half-life and variable absorption due to the poor esophageal emptying. The second treatment option, pneumatic dilatation, involves the stretching of the lower esophagus and is still considered the most effective non-surgical treatment for achalasia. Finally, surgical therapy for achalasia and the two major controversies concerning this laparoscopic treatment are discussed. The first involves the extent to which the myotomy is extended onto the stomach, and the second concerns the necessity and type of antireflux procedure to prevent GERD after myotomy. LARS and laparoscopic Heller myotomy are the agreed upon as the gold standards for surgical treatment of GERD and achalasia, respectively. In the hands of an experienced laparoscopic surgeon both are safe and effective treatments for patients with excellent subjective and objective long-term results with at least 90% patient satisfaction.

An outbreak of enterically transmitted non-A, non-B hepatitis in Pakistan.

An epidemic of enterically transmitted non-A, non-B hepatitis occurred at a college in Sargodha, Pakistan in early 1987. There were 133 clinical cases, an attack rate of approximately 20%. Though the disease was relatively mild, all clinical cases required hospitalization and prolonged convalescence. Nearly all cases were associated with a single water source. The epidemic ended when the water supply was improved. This is the 4th described epidemic of non-A, non-B hepatitis in Pakistan.

The historical impact of minimally invasive surgery.

At first there is an idea which asks for more comfort for the patient and equal results compared to conventional procedures. This means less pain and fatigue, quicker convalescence and shorter hospital stay. The new procedures requests an entirely new operative skill and a new technique with new instruments. Those were early developed in Germany. The roads on which this was performed will be described. In another chapter the history of this development is shown, especially the German, French and US inventors with a special view on their personal experiences and disappointments like in the German surgeon M_he and the gynecologist Semm from Kiel, Germany. But they all remained enthusiastic as a common personal quality. The new technique (MIC) was translated "Mickey-Mouse-Surgery" and medicolegal consequences like in M_he were usual events. Another example of misunderstanding of the impact of the new technique: the first publication of Semm about the laoaroscopically removed appendix has been withheld so long in Germany until it was published in the USA in the Journal "Obstetrics and Gynecology". Besides this it is reported about the life cycle of this innovation pointing out to the final promising report, the professional adoption and public acceptance and the randomized controlled trials. The last stage is characterized by "jumping on another train". Pictures are shown of those pioneers who had the idea, who understood what they were doing and who took the responsibility. The final chapter will deal with the consequences for the future generation of surgeons and their training and the unanswered questions as to further fields. Doubtlessly, the pioneer period did not come to an end yet. A glance into the future may be allowed.

Hyperbaric oxygen therapy in parenchymal liver disease.

Use and efficacy of hyperbaric oxygen therapy (HOT) in liver disease has not been established. A prospective control study of HOT in liver diseases was undertaken. Sixty cases were selected for this study (30 with HOT and 30 with conventional therapy only). Almost equal number of Hepatitis B virus surface antigen (HbsAg) positive cases were included in both groups. All patients were male. Only cases with serum bilirubin over 10 mg/dl were included in this study. It was found that study cases recovered faster, gained appetite and had an earlier sense of well-being. There was faster disappearance of pruritus, earlier achievement of normal liver function, HbsAg negativity and overall shorter duration of hospital stay and convalescence. Short term adverse effects were unremarkable.
