Ultrasound-guided endocavitary drainage of pelvic abscesses: technique,results and complications

AIM: To evaluate the experience in our institution with ultrasound-guided transrectal and transvaginal (endocavitary) drainage of pelvic abscesses. MATERIALS AND METHODS: Eighteen patients (four male, 14 female; mean age 55 years, range 30-78 years) presenting with pelvic abscesses were referred to our institution for therapeutic drainage over a 4 year period. Patients received broad-spectrum antibiotics prior to drainage, which was performed by either the transvaginal or transrectal route under ultrasound guidance. Patients were given sedo-analgesia in the form of midazolam and fentanyl and local anaesthesia was also employed. Eight French catheters were inserted into the abscess cavities, and patients were subsequently monitored on a daily basis by a member of the interventional radiology team until such time as it was deemed appropriate to remove the catheter. RESULTS: Eighteen catheters were placed in 17 patients, and transvaginal aspiration alone was performed in one patient. Drainage was successful in 16 of 17 patients, but a transgluteal approach was ultimately required in the remaining patient to enable passage of a larger catheter into an infected haematoma. The mean duration of drainage was 5 days, mean time to defervesce 2 days. Spontaneous catheter dislodgement occurred in four patients associated with straining, but this did not have any adverse effect in three of the four patients. CONCLUSION: Endocavitary drainage is an effective method of treatment for pelvic abscesses. Spontaneous catheter dislodgement does not affect patient outcome.     

Clinical value of dilatation and curettage for abnormal uterine bleeding

Dilatation and curettage was performed under anesthesia in outpatients in 1837 patients aged over 26 with a history of abnormal uterine bleeding not associated with pregnancy or ovulation. Fifty-one (2.8%) patients were found to have malignant disease. Of these, 47 patients had endometrial carcinoma. An additional 111 (6.0%) patients were found to have endometrial hyperplasia. The incidence of either malignant disease or endometrial hyperplasia was 9.7% in patients over the age of 40. Complications of this method were noted in 12 (0.7%) patients; only three patients needed to stay in hospital. Received: 1 February 2000 / Accepted: 19 May 2000     

Cost savings of manual vacuum aspiration for endometrial sampling in El Salvador

Despite the existence of less costly and less invasive techniques to evaluate abnormal uterine bleeding, sharp curettage continues to be the most common form of endometrial sampling in the less developed world. Because manual vacuum aspiration (MVA) equipment is often associated with abortion care in countries where abortion is illegal, many practitioners have been slow to incorporate its use for other gynecological conditions. In this study, MVA was introduced in a large teaching hospital in El Salvador as an alternative for patients with abnormal uterine bleeding. Hospital cost, length of stay and complication rates were compared in a prospective, nonrandomized controlled study of 163 patients assigned to either traditional sharp curettage or MVA services. Patients were assigned to each group depending on the availability of trained providers. Methodologies for cost-savings analysis were modified to obtain more precise cost estimates. Use of MVA was associated with a significant cost savings of 11% and a hospital stay that was 27% shorter as compared to sharp curettage. Cost savings could be much higher if MVA was institutionalized as an ambulatory procedure with minimal or no preoperative evaluation and postoperative stay.     

Treating incomplete abortion in El Salvador: cost savings with manual vacuum aspiration

When manual vacuum aspiration (MVA) was introduced to treat incomplete abortion at a regional training hospital in El Salvador, this study evaluated the impact of replacing sharp curettage with MVA. Hospital cost, length of hospital stay, complication rates and postabortion contraceptive acceptance were compared in a prospective, nonrandomized, controlled study of 154 women assigned to either traditional sharp curettage services or MVA services plus contraceptive counseling. Assignment depended on availability of trained providers. Compared to sharp curettage, use of MVA and associated changes in protocol led to a significant cost savings of 13% and shorter hospital stay of 28%. Dedicated family-planning counseling resulted in a threefold higher rate of contraceptive acceptance. Although the difference in cost was significant, much higher savings could be realized if minimal postoperative stays were implemented for both procedures. Barriers to early discharge include patient expectations, physician attitudes and training and hospital systems administration.     

Intravaginal administration of 9-deoxo-9-methylene-16,16-dimethyl PGE2 for cervical dilation prior to suction curettage

The study objective was to evaluate the safety and efficacy of a single 16, 16-dimethyl prostaglandin E2 (PGE2) vaginal suppository for achieving nonmechanical dilation when administered 12 hours prior to a 1st trimester suction curettage. 20 women between 7 and 12 weeks gestation who wanted an abortion volunteered to be the study subjects. 4 women were primigravidas and 16 were multiparous. All the women had normal medical histories and clinical examinations. Cervical dilatation, if any, was measured with Hegar dilators and recorded in millimeters. The serum concentration of prostaglandin reached its highest levels 4 hours following the insertion of the vaginal suppository. A higher level between 2 and 4 hours cannot be ruled out. Serum progesterone levels showed a slight decrease in 3 patients and no significant change in the other 4 patients. Cramping was noted in 17 of 20 patients. Its onset occurred between 1 hour and 8 hours post insertion. Vaginal bleeding occurred in 19 patients 1-12.5 hours. All patients were found to have a significant degree of cervical softening and cervical dilation when examined at 12 hours following the insertion of the suppository. 16 patients (80%) did not require any further medical dilation. The additional amount of cervical dilation for the 4 remaining patients ranged from 1 mm to 3 mm and was greatly facilitated by a softened cervix. 2 of these 4 women were primigravidas. 10 patients passed "tissue" per vagina during the observation period, prior to the termination procedure. Chorionic villi was confirmed by histologic examination in only 3 instances. The systemic absorption of the paracervical anesthetic was apparently increased since the initial group of patients complained of dizziness, numbness of tongue, and/or bitter taste in mouth. Study results indicate that a single 16, 16-dimethyl PGE2 vaginal suppository can "prime" the cervix so the further mechanical dilation was easily accomplished and in most cases (80%) was completely eliminated.     

Diagnostic yields of endoscopic ultrasound-guided fine-needle tissue acquisition according to the gastric location

The diagnostic accuracy of endoscopic ultrasound-guided fine-needle tissue acquisition (EUS-FNTA) according to the gastric location of subepithelial tumors (SETs) has not been well established. We aimed to evaluate the efficacy of EUS-FNTA for the diagnosis of gastric SETs according to tumor location.Thirty-three patients diagnosed with gastric SETs via EUS-FNTA from January 2016 to May 2018 were analyzed retrospectively. Patient demographics, diagnostic yields, and complications were evaluated.Nineteen patients (57.6%) were female, with a mean age of 57.7 years. Endoscopic ultrasound revealed a mean longitudinal diameter of 25.6 mm. The most common location of SETs was in the gastric body (n = 18, 54.5%), followed by cardia and fundus (n = 10, 30.3%), and antrum (n = 5, 15.2%). A 20-gauge biopsy needle was most frequently used (90.9%). The diagnostic yield was obtained in 23 patients (69.7%). The most common diagnosis was gastrointestinal stromal tumor (73.9%), followed by leiomyoma (17.4%). The diagnostic yield of SETs in gastric antrum (0/5, 0%) was significantly lower than that in the gastric body and cardia (23/28, 82.1%, P = .001). A case of immediate bleeding after EUS-FNTA occurred in 1 patient (3.0%) who recovered uneventfully. According to related literature, the overall diagnostic yield of SETs in gastric antrum was significantly lower than that in the gastric body, fundus, and cardia (29.7% vs 71.4%, P < .001, n = 191).EUS-FNTA is ineffective in the diagnosis of SETs in the gastric antrum. Although EUS-FNTA is an advanced diagnostic tool for gastric SETs, it is essential to develop more effective methods for the diagnosis of antral SETs.
