As minimally invasive surgery gains ground, it is entering realms previously considered to be relative contraindications for laparoscopy. We reviewed our experience with the laparoscopic approach to ...the management of small bowel obstruction (SBO).
From December 1997 to November 2002, 65 patients underwent laparoscopic treatment for SBO. The operating surgeon attempted to identify a transitional point between distended and collapsed bowel and then address the obstruction at that point.
Postoperative adhesions were the cause of the obstruction in 44 patients. Tumor was identified in five cases, hernia in four, bezoar in three, intussusception in three, acute appendicitis and pseudoobstruction in two cases each, and terminal ileitis in one case. The diagnostic accuracy of laparoscopy was 96.9%. Thirty-four patients (52%) were treated by laparoscopy alone. Thirteen patients (20%) required a small target incision for segmental resection. Eighteen operations were converted to formal laparotomy. The mean laparoscopy time was 40 min (range, 25-160). Patients resumed oral intake in 1-3 days. The complication rate was 6.4%. There were two deaths, but none related to laparoscopy. The mean hospital stay was 4.2 days.
Laparoscopy is a useful minimally invasive technique for the management of acute SBO. It is an excellent diagnostic tool and, in most cases, a therapeutic surgical approach in patients with SBO. However, a significant number of patients will require conversion.
Traditional approaches to incisional hernias (IH)--particularly in cases with large fascial defects--are plagued by a significant recurrence rate as well as frequent wound infections. The ...laparoscopic repair of incisional hernias was designed to offer a minimally invasive and tension-free technique that yields less morbidity and fewer recurrences than the standard open repair. Several years ago, we adopted the laparoscopic technique in our department and set out to appraise its touted advantages.
During the years 1997-2000, 103 patients underwent laparoscopic IH repair with implanted Dual Gore-tex mesh. Forty percent of them were obese, and 41% had undergone more than one previous attempt at conventional repair. All patients were discharged home within 24-72 hs.
In three patients, the operation was converted to open surgery due to severe adhesions and technical difficulties. In two cases, inadvertent enterotomies were repaired laparoscopically, and since there was no major spillage, the repair was continued as planned, with no adverse consequences. Twelve patients underwent additional laparoscopic procedures at the initial operation. Two graft infections and four recurrences were observed during the 1-49 month follow-up period.
Laparoscopic IH repair is technically feasible and safe in patients with large fascial defects as well as in obese patients. This operation decreases postoperative pain, hastens the recovery period, and reduces postoperative morbidity and recurrence.
Laparoscopic techniques have been proposed as an alternative to open surgery for the treatment of peptic ulcer perforation. This study compared the outcome of laparoscopic and open approaches for the ...repair of gastroduodenal perforations.
A retrospective review was conducted with 134 consecutive patients treated for gastroduodenal perforations. These patients included 122 with perforated duodenal ulcers, 10 with perforated gastric ulcers, and 2 with iatrogenic duodenal perforations. Whereas 68 patients were treated laparoscopically, 66 patients underwent conventional (open) surgery.
Laparoscopic repair was successful in 65 cases (96 %). The mean operating time was shorter with the laparoscopic technique (68 vs 59 min), but the difference was not significant. The duration of postoperative nasogastric aspiration and time to resumed oral intake were shorter in the laparoscopic group (2.6 vs 4.1 days and 4.4 vs. 5.2 days, respectively; p = 0.043). The postoperative analgetic requirements, and overall complications rate were significantly lower after laparoscopic surgery (p = 0.03 and p = 0.004, respectively). There was no statistically significant difference in hospital stay (5.1 vs 6.1 days) or mortality rate between the two procedures.
Laparoscopic repair of gastroduodenal perforations is a safe alternative treatment offering certain significant short-term advantages.
The purpose of this article is to describe our experience using laparoscopy in the management of emergent and acute abdominal conditions.
Between March 1997 and November 2001, 277 consecutive ...minimally invasive procedures were performed for various nontrauma surgical emergencies. The indications for operation were nonspecific abdominal pain in 129 cases (46%), peritonitis in 64 cases (23%), small bowel obstruction in 52 cases (19%), complications after previous surgery or invasive procedures in 24 cases (9%), and sepsis of unknown origin in 8 cases (3%).
Laparoscopy obtained a correct diagnosis in 98.6% of the cases. In 207 patients (75%), the procedure was completed laparoscopically. An additional 35 patients (12.5%) required a target incision. The remaining 35 patients (12.5%) underwent formal laparotomy. The morbidity rate was 5.8%. No laparoscopy-related mortality was observed.
For patients with abdominal emergencies, the laparoscopic approach provides diagnostic accuracy and therapeutic options, avoids extensive preoperative studies, averts delays in operative intervention, and appears to reduce morbidity.
Objective: Our purpose was to evaluate in vitro the effect of a high partial pressure of carbon dioxide environment used in laparoscopy on metabolic and immune response of various human peritoneal ...cells.
Study Design: Polymorphonuclear leukocytes were obtained from 5 healthy volunteers, peritoneal macrophages were obtained from the effluent of 8 patients undergoing continuous ambulatory peritoneal dialysis, and human peritoneal mesothelial cell cultures were prepared from omentum derived from 5 patients undergoing elective surgery. The cells were exposed to a laparoscopy-like environment (1 atmosphere carbon dioxide and 0.2 atmosphere oxygen), to a control gas mixture (1 atmosphere helium and 0.2 atmosphere oxygen), or air for 3 hours. After exposure to gas mixtures, cell functions were tested at various recovery periods.
Results: Three hours of exposure to a high partial pressure of carbon dioxide had no effect on viability of peritoneal macrophages and human peritoneal mesothelial cells, tested by trypan blue dye uptake and lactate dehydrogenase release. A high partial pressure of carbon dioxide decreased the mitochondrial dehydrogenases activity of peritoneal macrophages and human peritoneal macrophage cells by 60%, assayed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction. High partial pressure of carbon dioxide blocked the superoxide release from activated polymorphonuclear leukocytes and the secretion of interleukin 1β from stimulated peritoneal macrophages, and human peritoneal macrophage cells were decreased by 15% and 30% and the secretion of tumor necrosis factor-α from peritoneal macrophages was suppressed by 85%. Mitochondrial activity, polymorphonuclear leukocyte function, and interleukin 1β and tumor necrosis factor-α secretion returned to normal after a recovery period of 12 to 24 hours, 4.5 hours, and 24 hours, respectively. In the control experiments exposure of cells to helium had no suppressive effect.
Conclusions: Exposure of cells to a high partial pressure of carbon dioxide environment suppresses the inflammatory and metabolic responses of peritoneal cells. We suggest that this suppressive effect may contribute to the low postsurgery adhesion formation and the reduction in postoperative pain observed in laparoscopy. Nevertheless, the suppression of the immune response should also be taken into account for operations involving a high risk of bacterial dissemination. (Am J Obstet Gynecol 1998;179:1503-10.)
Operations of laparoscopic adjustable gastric banding (LAGB) have been fulfilled on 2958 patients for treatment of different forms of obesity. The age of the patients was 38 +/- 7.5 years (from 16 to ...60 years). There were 80% of women (2366) and 20% of men (592). Mean preoperative body mass index was from 35 to 54 kg/m2, i.e 43 +/- 3.8 kg/m2, fluctuating from 35 kg/m2 to 54 kg/m2. Bands of the following firms were used: Lap Band, Inamed, (USA), AMI Soft Band, Austria, Swedish Band J & J, USA. A description of complications in the early and late postoperative periods are given, associated with the dilatation of the formed "miniature ventricles, occlusion of intercommunication between the miniature ventricle and large ventricle with disturbed evacuation of the content, erosion of the gastric mucosa in the area of the band without its penetration, slippage of the band, complications associated with the regulation system etc. Recommendations were worked out for decreasing the number of complications. The data obtained suggest that LAGB is a highly effective method giving good results of treatment of patients with obesity and coexisting diseases. Most of the appearing complications can be eliminated laparoscopically.
The laparoscopic adjustable gastric band (LAGB) is widely used for treatment of morbid obesity. Band slippage is a well known long-term complication. Herein, we present a patient with band slippage ...who developed strangulation of the fundus with irreversible necrosis. The chosen surgical solution was minimally invasive. A diagnostic laparoscopy and consequently resection of the necrotic fundus was performed. A postoperative symptomatic left pleural effusion resolved after chest tube insertion. One week later, the patient was discharged with satisfactory results.
Autonomic dysfunction in Parkinson's disease (PD) is considered a late complication of the disease or an adverse effect of anti-parkinsonian medications. Morphological changes are demonstrated only ...by postmortem examination. The study objective was to evaluate peripheral autonomic neural involvement in PD using punch skin biopsy. The study sample included 22 patients (mean age 50 +/- 7.7 years, mean disease duration 5.3 +/- 3.8 years) and 19 controls. Four-millimeter skin biopsies were immunohistochemically stained with anti-PGP 9.5 antibody. Autonomic innervation of the blood vessels, sweat glands, and erector pili muscles was assessed and rated from 0 (normal) to 2 (severe). Cutaneous autonomic innervation was decreased in patients compared to controls. Semi quantitative analysis demonstrated reduced autonomic innervation of the blood vessels (1.0 +/- 0.8 vs. 0.42 +/- 0.8 in controls; p < 0.02), of sweat glands (0.95 +/- 0.67 vs. 0.47 +/- 0.61; p < 0.02) and of the erector pili muscles (1.06 +/- 0.55 vs 0.21 +/- 0.42; p < 0.001). This method demonstrates that the peripheral autonomic system is affected in PD at early stage of the disease and that autonomic involvement in PD may be more prevalent than previously thought.
The use of tyrosine kinase inhibitors (TKIs) has resulted in successful treatment of KIT-positive neoplasms. Carcinosarcoma is a very aggressive neoplasm. Consequently, c-kit expression may have ...significant clinical implications for this tumor. The purpose of the present study was to assess c-kit expression in the carcinomatous and sarcomatous element of carcinosarcoma to identify if KIT represents a therapeutic target for treatment of this neoplasm.
Immunohistochemical staining for c-KIT was performed on paraffin-embedded tissue blocks of 20 consecutive uterine specimens with carcinosarcoma, 40 with endometrial carcinoma, and 12 with atrophic endometrium. Two pathologists assessed the scoring index of staining.
In the stromal element of carcinosarcoma, no immunohistochemically c-KIT stained cells were observed and in the epithelial element, a low scoring index of staining was present. In endometrial endometrioid carcinoma, the scoring index was high in only 15% of the specimens. In the atrophic endometrium, a low scoring index was seen in all specimens.
Our results seem to suggest that c-kit probably plays no major role in the pathogenesis of the majority of these tumors while it may be involved in the pathogenesis of some endometrial carcinomas. In view of the multiple molecular targets that are activated by imatinib mesylate, no definitive conclusions can be drawn with regard its effectiveness in carcinosarcomas based on the present study.
Further studies of c-kit expression in larger series of carcinosarcomas in order to settle the controversial issues with regard to frequency of expression, prognostic, and clinical value are warranted.
SUMMARY
A 42‐year‐old woman developed a purplish, tender nodule on her wrist of 6 months duration. Histological examination showed a well‐circumscribed lesion situated in the dermis and subcutis ...characterized by numerous, dilated thin‐walled vascular spaces surrounded by sheets of glomus cells. The histological findings are characteristic of the diagnosis of an uncommon type of glomus tumour, known as glomangioma.
