Small bowel obstruction and previous gynecologic surgery.

We reviewed the cases of women admitted to LSU Medical Center in Shreveport with the diagnosis of "small bowel obstruction" from Jan 1, 1975 to June 30, 1981. Review of the charts of patients who had exploratory laparotomy for relief of the obstruction showed that 83% of them had had previous abdominal surgery. Furthermore, 67% of the patients had had an abdominal hysterectomy. In 100% of the cases of obstruction after abdominal hysterectomy, there were adhesions to the site of reperitonealization or to the anterior abdominal wall. This study shows a higher incidence of small bowel obstruction after gynecologic surgery than has been previously reported.

Comparison of low molecular weight heparin vs. unfractionated heparin in gynecological surgery. II: Reduced dose of low molecular weight heparin.

In a double blind, randomized trial the hemorrhagic complications of a reduced dose of low molecular weight heparin (LMWH) (Fragmin, KabiPharmacia) were compared to those of the conventional dose of unfractionated heparin (UH). 2500 anti-XaU of LMWH was given once daily and UH in a dose of 5000 anti-XaU twice daily. During a one year period 141 patients undergoing gynecological surgery were included in this study. The patients were examined clinically for hematomas and for deep venous thrombosis (DVT) on the third and fifth day. Venography was performed when DVT was suspected. No patients developed clinical DVT. One woman in the LMWH group had pulmonary embolism 3 days after the prophylaxis was stopped. Two women in the LMWH group died, one from a stroke on day 2, one from cancer on day 39. There was no significant difference in serious bleeding complications between the two regimens, 20% in the LMWH group and 14% in the UH group. Even with the reduced dose of LMWH the mean plasma concentration of heparin in the LMWH group was higher (mean 0.14 anti-XaU/ml) than in the UH group (0.029 anti-XaU/ml) 3 hours after injection on the 2nd postoperative day. A reduced dose of LMWH (2500 anti XaU once daily) does not cause more bleeding complications than the conventional heparin regimen to prevent thrombosis, as was the case in our previous study with 5000 anti XaU of LMWH once daily.

Prospective analysis of a fever evaluation algorithm after major gynecologic surgery.

OBJECTIVE: We performed a prospective trial to evaluate the feasibility, accuracy, and safety of a postoperative fever algorithm that is based on symptoms and physical examination in an attempt to decrease the random use of urine cultures, blood cultures, and chest radiographs. STUDY DESIGN: Our fever algorithm consisted of assessing all febrile postoperative patients for signs and symptoms of infection. If none were present, no tests were ordered. RESULTS: Twenty-eight of 105 consecutive patients (27%) had postoperative fever after major gynecologic surgery. Three of 28 febrile patients (11%) were evaluated with tests according to the algorithm. Two of 28 febrile patients (7%) were evaluated in violation of the algorithm. Four febrile patients (14%) had documented infections. Two patients had infections within the first 30 days after discharge. Compared with our previous retrospective review, significantly fewer febrile patients were evaluated with testing with a significantly increased yield of positive test results. CONCLUSIONS: Our postoperative fever evaluation algorithm that is based on symptoms and physical examination is feasible, is safe, decreases random testing, and increases the yield of positive test results.

Application of SPI-guided analgesia in laparoscopic gynecologic surgery: a randomized controlled trial evaluating the remifentanil-sparing effect and predictive value of time-weighted SPI.

This study aimed to achieve two primary objectives: (1) to evaluate the opioid-sparing effect of Surgical Pleth Index (SPI)-directed analgesia during surgery via a randomized controlled trial (RCT), and (2) to propose and preliminarily assess a novel dynamic metric, Threshold-based Time-Weighted SPI (Tb-TW-SPI), which integrates stimulus intensity and duration, for its predictive efficacy regarding postoperative moderate-to-severe pain. Employing an RCT combined with exploratory analysis, 61 patients undergoing elective laparoscopic gynecologic surgery were randomized into an SPI-directed analgesia group or a conventional analgesia group. The primary outcome was total intraoperative remifentanil consumption. Postoperatively, an exploratory analysis of the control group data evaluated the correlation between Tb-TW-SPI and Numeric Rating Scale (NRS) pain scores in the post-anesthesia care unit (PACU), calculating its predictive value for moderate-to-severe pain (NRS ≥ 4). Results: The SPI-directed group required significantly less intraoperative remifentanil than the conventional group [median (IQR): 5.84(5.02,6.62)vs. 6.96(5.81,8.19)µg/kg/h; P = 0.016]. Postoperative pain scores did not differ significantly between groups (P > 0.05). Exploratory analysis of the conventional analgesia group revealed that Tb-TW-SPI values were significantly higher in patients with moderate-to-severe postoperative pain (NRS ≥ 4) compared to those without (P = 0.0417).The area under the ROC curve for Tb-TW-SPI predicting this pain was 0.74 (95% CI: 0.52-0.96), with 67% sensitivity and 76% specificity at an optimal cutoff of 1210. This RCT suggests that SPI-directed analgesia can safely and moderately reduce intraoperative remifentanil consumption. Furthermore, the proposed Tb-TW-SPI metric, in this exploratory analysis, suggests potential for predicting postoperative pain, though this finding requires validation in larger cohorts with higher-frequency SPI sampling, offering a new direction for SPI interpretation. Large-scale, multicenter trials are warranted to validate the predictive utility of Tb-TW-SPI. Clinical Trial Registration, China Clinical Trial Registry: ChiCTR2400088444.

Preoperative assessment and risk reduction in gynecologic surgery patients.

UNLABELLED: The prevention of complications during or after surgery is of interest to surgeon and patient alike. Identification of a patient's risk for perioperative complications requires a mix of good fundamental medicine, clinical and laboratory assessment tools, and clinical experience. Once identified, reduction of modifiable risk leads to better clinical outcomes. Active risk reduction is a combination of general strategies known to benefit all patients plus focal strategies designed to reduce individual patient risk. This article will review preoperative risk identification strategies and risk reduction techniques applicable to gynecologic surgery patients. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader will be able to summarize the various risk prediction strategies, explain the various methods used to identify risk, and describe potential ways to reduce perioperative risk.

Low-dose heparin in gynecologic surgery: effect on blood coagulation tests.

The laboratory control of low-dose heparin therapy is generally regarded as unnecessary. A laboratory study of the effects of low-dose heparin was performed using different methods: an amidolytic method and a method involving the inhibition of factor Xa in a coagulation test. Variations in partial thromboplastin time, recalcification clotting time, thrombin time and the plasma antithrombin III levels were also studied. These tests were repeated (days 0, 1, 3, 8) in 27 women between the ages of 27 and 62 years who were undergoing gynecological surgery. They received 5,000 IU of heparin either twice or thrice daily. There was no correlation between heparin levels in the blood and global clotting tests simultaneously performed. The plasma heparin levels varied between 0 and 0.15 IU/ml with both methods. A detectable heparin concentration on days 1, 3 and 8 was present in only half of the cases receiving the twice daily regimen. The plasma antithrombin III activity and concentration were not modified during treatment.

Neurosecretory response of hypothalamic-hypophyseal axis to spinal anesthesia, minor gynecological surgery and irradiation.

The effect of spinal anesthesia, dilatation and curettage plus the first intracavitary radiotherapy or only that of intracavitary radiotherapy on growth hormone (HGH = the response of anterior pituitary) and arginine vasopressin (AVP = the response of posterior pituitary) levels was studied in 10 patients suffering from cervical or endometrial uterine cancer. Differing from earlier animal studies, irradiation had no effect on GH or AVP secretion, nor was there any change in the hormone levels following spinal anesthesia and dilatation and curettage. The neurosecretory response of hypothalamic-hypophyseal axis to spinal anesthesia and minor gynecological surgery appears to be minimal.

Pharmacodynamic effects on blood coagulation of a new low molecular weight heparin (alfa-LMWH) in healthy volunteers and gynecological surgery patients.

The pharmacodynamic properties of a new LMWH (alfa-LMWH) were investigated in 8 healthy volunteers after single subcutaneous administrations of 7,500, 15,000 and 30,000 anti-XaU doses at weekly intervals. Anti-Xa and anti-IIa heparin activities were monitored together with aPTT, thrombin time, bleeding time and euglobulin lysis time. No relevant changes in bleeding time or major side-effects were ever recorded. A group of 26 patients submitted to gynaecological surgery were then investigated to determine the dosage schedule for prophylaxis of post-operative deep vein thrombosis. Two subgroups received daily subcutaneous doses of 7,500 and 15,000 anti-XaU alfa-LMWH respectively, beginning 2 h before surgery; the third subgroup received 5,000 IU calcium heparin three times daily over the seven postoperative days. The following tests were peri-operatively monitored: anti-Xa heparin activity, aPTT, PT, fibrinogen, Antithrombin III. No differences in intra-operative bleeding or side-effects were recorded. On the basis of the levels of anti-Xa heparin activity and the negligible effects on aPTT, the dose of 7500 anti-XaU was selected at single daily administration for thromboprophylaxis in gynecological surgery.

Infection After Gynecologic Surgery: Implications of Racial Leukopenia in Black Women.

Differences in the normal peripheral white blood cell count (WBC) among people of various racial backgrounds are well recognized, and one familiar example is the decrease in the WBC of African-Americans relative to that of Caucasian subjects, a phenomenon that has been termed "racial leukopenia." Since the WBC is commonly used as an early indicator of infection, information regarding this phenomenon is pertinent: Such leukopenia could give rise to a falsely low (i.e., in the normal range) WBC during a significant infectious event. We therefore conducted a retrospective study to describe the incidence of this leukopenia among Black women in Louisiana and to follow their WBC levels in response to infection after elective gynecologic surgery. We found that 6.5% of these women exhibited a preoperative WBC < 3.5 x 10^3 cells/mm3, which represents the lower limit of normal for this measure. Although these women did exhibit a 2- to 3-fold rise in their WBC in response to infection, their peak WBC remained less than 11.0 x 10^3/mm3, a value below the upper limit of normal.

Reduction of hospital cost and administration of prophylactic antibiotherapy in gynecological surgery.

The present study attempts to evaluate the efficacy and safety of three of the most popular third-generation cephalosporins, and demonstrates the reduction in cost resulting from their use. Our study included 223 women admitted for abdominal hysterectomy (mean age 54), 200 of whom were assigned randomly to one of four groups. The first group did not use an antibiotic prophylaxis. The second group used ceftriaxone, the third cefotaxime and the fourth ceftazidime. In the three treatment groups one 2-g dose of the antibiotic was provided 60 min before the operation. Additional doses were given only if post-operative infection was established. Our results indicated that one dose of antibiotic prophylaxis with third-generation cephalosporins reduces the morbidity in gynecological surgery. Cefotaxime proved to be the most cost-effective of these three cephalosporins, with low morbidity and a low rate of hospitalization.

[Development of better tolerated prosthetic materials: applications in gynecological surgery].

UNLABELLED: Meshes have come to be widely used for surgical repair of the dysfunctional pelvic floor. The problem to date has been mesh intolerance. History. The first meshes were made with silver filigrees or stainless steel. Non-metallic and non-absorbable synthetic prostheses include nylon, silastic, polytetrafluoroethylene as well as expansive polyester and polypropylene forms. Most of the absorbable prostheses are made of polyglycolic acid and polyglactine 910. Classification. Four groups of biomaterials can be described according to pore size. Mechanical and biological properties. The mechanical properties of meshes have been tested industrially for resistance, pliability, elasticity and ductile qualities. These properties depend on type of tissue structure (woven or knitted) and the type of fiber used (mono and multi-filaments). The goal is to obtain a "silent" material, i.e. a material which does not trigger a host tissue reaction. Introducing the foreign body induces a "scarring" response. This fibroblastic reaction replaces the inflammatory reaction, leading to progressive colonization of the prosthesis. The major risk is infection caused by a disturbance of the inflammatory phase and bacterial development. Bacteria can be trapped in fibrotic tissue, with the risk of delayed infection. Immunological reactions may have an additive effect. These problems are not encountered with absorbable meshes. An ideal implant material must: not undergo physical modification by tissue fluids, be chemically inert, not trigger inflammatory or foreign body cell response in body tissues, be noncarcinogenic and nonallergenic, be capable of resisting mechanical stress and sterilization, and be able to be manufactured in the necessary shape. Polyester, polypropylene and expansive polytetrafluoroethylene fulfill these criteria. The ideal mesh. Eleven criteria are proposed. Complications for hernia repair. Infection and seroma are the most frequent complications with micro-porous meshes. Macro-porous meshes can cause erosive phenomena and adhesions. Retraction of synthetic tissues is observed in 20 to 30% of cases. Meshes in gynecology. In gynecology surgery, meshes made their first appearance in trans-abdominal sacrocolpopexy and slings. A detailed review of complications found in 32 articles studying slings and 22 studying sacrocolpopexy with approximately 10 types of meshes shows that intolerance of slings has oscillated between 1% with Prolene and 31% with Gore-Tex; for abdominal sacrocolpopexy the rate was between 1.7% with Prolene and 20% with Teflon. Rejection phenomena appear during the first year and are proportional to the surface area of the synthetic tissue and the proximity of the vaginal scar. New materials have been proposed over the last ten years for prolapse surgery, notably for cystocele, which accounts for 70% of all repair procedures. Nearly fifteen studies have reported a level of intolerance reaching 6%, the large majority of the meshes used being Prolene meshes. Our personal experience with 87 repair procedures has led us to the conclusion that Prolene is the most adapted mesh, allowing free tension between the bladder and the anterior vaginal wall. CONCLUSION: Continuous evaluation is needed to study these replacement materials which should in theory, improve the rate of recurrence, which is at present 20% with classic procedures not using a mesh.

Prophylactic ip injection of bupivacaine and/or morphine does not improve postoperative analgesia after laparoscopic gynecologic surgery.

PURPOSE: To determine the effectiveness of ip bupivacaine and/or morphine for postoperative analgesia after laparoscopic surgery. A controversy exists on the effectiveness and clinical value of ip injection of local anesthetics for postoperative analgesia. A possible peripheral analgesic effect of morphine after ip injection remains debated as well. METHODS: We conducted a randomized, double-blinded, study to compare the efficacy of prophylactic ip administration of 0.9% saline (n = 16), 0.5% bupivacaine (100 mg, n = 15), morphine (3 mg, n = 16) and a mixture with 0.5% bupivacaine (100 mg) and morphine (3 mg, n = 18) to reduce both postoperative pain scores and analgesic requirements after gynecologic laparoscopic surgery. A multimodal analgesia regimen (acetaminophen, nonsteroidal anti-inflammatory drugs and morphine) was used for postoperative analgesia. RESULTS: No difference was observed in postoperative pain scores (visual analogue scale at rest and on coughing), or analgesic requirements during the first 24 postoperative hours between the four groups. There was also no significant intergroup difference in sedation scores and incidence of nausea and vomiting. CONCLUSION: When multimodal postoperative analgesia is used, prophylactic ip administration of 100 mg bupivacaine and/or 3 mg morphine does not significantly improve postoperative analgesia in patients undergoing laparoscopic gynecologic surgery.

The redistribution of benign gynecologic surgery.

The program directors of obstetrics-gynecology residencies in the United States were questioned regarding their perceptions of benign gynecologic surgical volume change at their institutions. Most responding departments had experienced a decline volume during the 5 years prior to the study. This volume decrease tended to be more frequent and more pronounced in those programs involving care of a high percentage of indigent patients. Conversely, programs with a predominantly nonindigent patient population tended to experience increases in volume. Many factors are responsible for this redistribution, including a change in gynecology, itself, which has become increasingly occupied with noninvasive ambulatory techniques.
