[A comparative study of the suction and customary curettage methods in the termination of pregnancy (author's transl)].

90 hysteroscopies using CO2 were performed to evaluate differences in effectiveness between the customary curettage and the suction methods in terminating pregnancy during the first trimenon. Following suction, the uterine cavity was nearly always thoroughly evacuated. Very seldom is there any residual tissue seen. On the contrary, the uterine cavity following termination by customary curettage was almost never completely evacuated. Very often rest tissue of decidua, usually chorionic, in some cases with villous structures, were found. Tissue remnants following termination by either method were removed by target biopsy or curettage and examined histologically. Having made the above observations and comparison, it must be concluded that the suction method is clearly the more advantageous. If applied correctly, it becomes unnecessary to perform curettage right after the suction.

Comparison of the footpump suction evacuator with the manual vacuum aspirator for uterine evacuation.

OBJECTIVE: To compare the efficacy of a novel footpump suction evacuator with the manual vacuum aspirator in the management of women with incomplete abortions requiring uterine evacuation. DESIGN: A prospective comparative analysis of women allocated to either manual vacuum aspiration of the uterus or footpump suction evacuation, following first- or second-trimester incomplete abortion. SETTING: The gynaecology casualty theatre, Groote Schuur Hospital, Cape Town. PATIENTS: 121 women with first- or second-trimester abortions. Patients with signs of septic abortion were excluded from the study. INTERVENTIONS: Uterine evacuation under general anaesthesia by means of a manual vacuum aspirator or a novel footpump suction evacuator. OUTCOME MEASURES: Endpoints assessed included duration of the procedures, ease of evacuation, estimated blood loss, volume of products of conception obtained, postoperative complications of the procedures and amount of analgesia required postoperatively. RESULTS: The manual vacuum aspirator and footpump suction evacuator appeared equally effective for uterine evacuation. There were no significant differences in the endpoints assessed. CONCLUSIONS: Both methods appear equally effective for uterine evacuation.

Suction-assisted ureteroscopy compared with traditional ureteroscopy for renal stones ≤ 2 cm: a systematic review, Bayesian network meta-analysis and meta-regression.

INTRODUCTION AND OBJECTIVE: Suction-enhanced flexible ureteroscopy (URS) aims to improve stone clearance and reduce complications. We performed a Bayesian network meta-analysis to compare the efficacy and safety of flexible aspiration navigable sheaths (FANS) and direct in-scope suction (DISS) for renal calculi ≤ 2 cm. METHODS: A systematic search of PubMed, MEDLINE, Scopus, Web of Science, and Google Scholar was conducted through June 2026. Comparative studies of FANS, DISS, or conventional access sheaths for renal stones ≤ 2 cm were included. The primary outcome was 30-day stone-free rate (SFR). Secondary outcomes included operative time, fever, sepsis, and complications. A Bayesian random-effects network meta-analysis synthesized direct and indirect evidence. RESULTS: Seventeen studies including 3,657 patients (1,677 FANS, 56 DISS, 1,924 control) were included. FANS showed higher SFR (OR 2.5, 95% CrI 2.0-3.1), while grouped DISS had a similar but less precise effect (OR 3.1, 95% CrI 1.0-8.8). Calyxo V2 had the highest SFR (OR 5.4, 95% CrI 1.0-29.0), whereas PUSEN showed no significant difference (OR 1.6, 95% CrI 0.41-6.3). FANS reduced postoperative fever and complications. FANS also showed lower odds of postoperative sepsis (OR 0.40, 95% CrI 0.12-0.97). CONCLUSIONS: Suction-assisted ureteroscopy improves SFR for renal calculi ≤ 2 cm. FANS was associated with shorter operative time, fever, and complications. DISS systems show promising but limited results, with performance differing by technology configuration. Larger prospective trials are needed.

The Hanna suction punch block and trephine system for penetrating keratoplasty.

We describe a new system for corneal trephination. The system for cutting donor buttons consists of a concave Teflon well in which the donor corneoscleral shell is secured by gentle suction. A cylindrical guide ensures that the disposable razor blade trephine is centered and is perpendicular during punching from the endothelium. The suction mechanical trephine used for the host has the following features: (1) a gun-sight alignment system for reliable centering, (2) a 360 degrees limbal suction ring that secures the trephine to the eye and ensures perpendicularity of the cut, (3) support surfaces on either side of the disposable razor blade that support the cornea during cutting to create near-vertical uniform wound margins, (4) rotation of the trephine with a manually operated gear system for smooth cutting, and (5) a calibration device that governs the extension of the blade and also allows cutting without descent of the blade.

Outcomes in suction coagulator adenoidectomy.

OBJECTIVES: To assess the feasibility of suction coagulator adenoidectomy relative to adenoid size and to document patient-based outcomes and satisfaction with surgery. DESIGN: Historical cohort study. SETTING: Referral-based academic pediatric otolaryngology practice. PARTICIPANTS: Consecutive series of 118 children older than 3 years (mean age, 6.5 years) undergoing adenoidectomy alone. INTERVENTION: Video nasopharyngoscopy followed by suction coagulator adenoidectomy as part of routine clinical care. An outcome survey was completed by telephone. OUTCOME MEASURES: Duration of surgery, estimated blood loss, complications, parent satisfaction, and clinical outcomes. RESULTS: The distribution of preoperative adenoid grades as determined by nasal endoscopy were as follows: grade 2 (>or=33% to <66% choanal obstruction), 7%; grade 3 (>or=66% to <90% obstruction), 48%; and grade 4 (90%-100% obstruction), 45%. The mean (SD) surgical time of 10.5 (3.0) minutes was unrelated to adenoid grade (R = 0.014; P =.88). All blood loss was less than 15 mL (<5 mL for 67%), and the only complication was a loose tooth. The parents of 98 patients (83%) were contacted a mean of 30.4 days after surgery: 95 (97%) reported less-labored breathing, and 94 (96%) were satisfied with the surgical results. Only 5 patients (5%) required a follow-up visit within 30 days of surgery. CONCLUSIONS: Suction coagulator adenoidectomy proved safe and rapid, regardless of the adenoid size. Surgical outcomes were very favorable, with nearly all parents reporting satisfaction with the procedure and improvement in their child's breathing.

Morphological changes of neural and vascular peptides in human skin suction blister injury.

Suction blister injury is an experimental model for the investigation of the possible derangement of dermal/epidermal interaction in injury. An extensive fibre network can be stained in skin using antisera to the pan-neuronal marker protein gene product 9.5 (PGP) and the sensory neuropeptide calcitonin gene-related peptide (CGRP), while microvessels are identifiable with antisera to the endothelial marker von Willebrand's factor (vWf) and the peptide endothelin (ET). To investigate the possible involvement of superficial cutaneous innervation and microcirculation during the repair process in injury, human skin biopsies taken at different times after suction blister injury were investigated by quantitative immunohistochemistry. Neural and endothelial changes were seen in both edge and blister areas. PGP- and CGRP-immunoreactive nerves showed an increase in both areas compared with control skin up to 6 h after injury, followed by a decrease which lasted until 72 h. This was followed by a gradual increase of both nerve types starting from the blister edge and lasting up to 8 days after injury when the values were similar to controls. Similarly, in the blister area of the skin, vWF-immunoreactive capillaries showed statistically significant increases between 0 and 6 h after injury, followed by a decrease at 12 and 18 h which was maintained up to 72 h. ET-1 immunoreactivity showed a similar, although more variable, pattern of changes. At the blister edge from 23 h onwards, both vWf and ET-1 immunoreactivities showed a second increase from the edge of the blister spreading towards the centre of the blister ahead of the nerve increase. This lasted up to 8 days, when vWf immunoreactivity showed a statistically significant increase compared with control skin. Generally the numerical increase observed at early time points was accompanied by a strong staining intensity, which reverted to a normal staining intensity at later time points. These results suggest that there is a reactive process for all immunoreactive elements in the early stages of injury, followed by changes indicative of neuronal and endothelial damage (depletion phase) and the subsequent repair process. The repair started with re-epidermalization from the blister edge, followed by revascularization and, lastly, by reinnervation of the tissue. These results indicate a close relationship between epidermis, blood vessels, and nerve fibres during the healing process which follows suction blister injury.

Refraction changes during elevation of intraocular pressure by suction cup, their reflection in the pattern visual evoked cortical potential and their compensation.

Visual evoked cortical potential studies using pattern stimuli with the intraocular pressure raised artificially by the suction cup method have been reported. Possible changes in the refraction of the eye due to the method employed and their influence on the pattern visual evoked cortical potential have not been considered. Changes in the refraction of the eye during artificial intraocular pressure elevation and the influence of such changes on pattern visual evoked cortical potentials were studied. The refraction changes were found to depend on the shape of the suction cup. They could be compensated for by employing properly shaped suction cups and contact lenses. The behavior of amplitude and latency of the pattern visual evoked cortical potential at artificially elevated intraocular pressure with compensation for refraction changes has been studied and found to depend in a characteristic manner on ocular perfusion pressure.

Nasogastric suction in alcoholic pancreatitis.

In order to assess the usefulness of nasogastric suction in acute alcoholic pancreatitis, 37 patients with alcoholic pancreatitis were prospectively investigated. The study failed to demonstrate efficacy of nasogastric suction in those patients with mild disease. Application of a system of prognostic signs proved useful in discriminating between mild and severe disease. Routine use of ultrasound examinations detected three pancreatic pseudocysts before they became clinically apparent. In instituting appropriate therapy in mild pancreatitis, factors such as patient comfort should be considered in the absence of proven significant value of nasogastric suction.

A randomized trial comparing cimetidine to nasogastric suction in acute pancreatitis.

Clinical and experimental evidence has suggested that the use of cimetidine might be harmful to patients with acute pancreatitis. We conducted a randomized study comparing cimetidine to nasogastric (NG) suction in 95 patients with 103 episodes of mild to moderately severe, acute or relapsing pancreatitis (86.4% alcohol related). The groups were comparable on entry to the study, and daily evaluation of several clinical and laboratory criteria revealed no consistent differences between the two groups. When these same criteria were evaluated for time of return to normal, if abnormal on entry to the study, no differences were found. The cimetidine group had a significantly shorter stay in the hospital than did the NG group (6.8 +/- 2.7 vs 8.5 +/- 4.8 days). Neither the incidence of relapse or complication nor the duration and extent of hyperamylasemia were significantly different between patients treated with cimetidine or NG suction. We conclude that cimetidine is safe to use in patients with mild to moderately severe alcohol-related pancreatitis, but it offers minimal advantage over NG suction.

Suction curettage lipectomy.

In 1981, we started performing minor suction curettage with the elements available at that time. In the course of surgical practice, we have modified the suction system and devised a new pattern of suction cannulas adapted for this kind of operation, with all possible variants. During this period, we have treated 150 patients, ranging in age from 17 to 63 years. In the light of present knowledge, we consider it time to provide a systematization of this technique.

Body sculpturing by lipo-suction extraction.

Classical open surgical contouring and sculpturing of the body has required significant scarring with long incisions and wide depressed scars. During the last decade, a small number of European surgeons have pioneered techniques for suction lipectomy. Illouz introduced the concept of lipolysis and blunt cannula extraction. The method described herein, which is termed lipo-suction, is a dry technique. No lipolytic solutions or local anesthetic solutions are injected. The technique relies on mechanical disruption and suction extraction of adipose tissue. The instrument is a rigid blunt-ended extractor with dull apertures. Postoperative care is a significant factor in reducing the rate of seroma formation to less than 1%.

Passive vs. closed suction drainage after perineal wound closure following abdominoperineal rectal excision for carcinoma. A multicenter, controlled trial. The French Association for Surgical Research.

PURPOSE: Because evacuation of effusion or collection could depend on the type of drainage, we compared the effects of closed suction drainage with passive drainage through tubes or undulated drains after abdominoperineal rectal excision for carcinoma on early and late perineal wound healing. METHODS: Of 234 consecutive patients undergoing abdominoperineal rectal excision for carcinoma between January 1983 and August 1990, unsatisfactory hemostasis or gross intraoperative septic contamination were recorded in 48 patients who were not included in the trial. After rectal excision and closure of the perineum, the remaining 186 patients were randomized to receive passive drainage (PD; n = 96) or closed suction drainage (SD; n = 90). Eighteen patients were withdrawn because of protocol violation, and three were lost to follow-up, leaving 165 (89 PD and 76 SD) patients for analysis. Preoperative factors (sex, age, degree of obesity, weight loss, anemia, or presence of ascites), intraoperative and pathologic findings (Dukes stage), and postoperative courses (recurrence, late mortality) were similar in both groups. All patients were followed up for 12 months or until death. RESULTS: The rate of perineums healed at one month was significantly lower (P < 0.05) in PD (55/89 = 61 percent) compared with SD (54/72 = 75 percent) patients. At three months, the rate of healed perineums no longer differed between the two groups (70/87 = 81 percent vs. 60/72 = 84 percent). The number of vaginal fistulas, secondary reopenings, and perineums not healed at 12 months was similar in both groups. Median duration to complete healing was similar in both groups (23 vs. 21 days, respectively). On the other hand, three retained drains were seen in PD patients only. The median duration of hospital stay was identical in both groups (22 days). Seven patients died in the early postoperative period, including one in the PD group and six in the SD group. There was no significant difference in the number of late deaths (3 vs. 7) in PD and SD patients, respectively. CONCLUSION: These results suggest that closed suction drainage should be used after abdominoperineal rectal excision with satisfactory hemostasis or absence of gross introperative septic contamination.

Simple and effective surgical treatment of pilonidal sinus: asymmetric excision and primary closure using suction drain and subcuticular skin closure.

PURPOSE: This study was planned to evaluate prospectively the results of 112 pilonidal sinus cases treated surgically by using asymmetric excision and primary closure with suction drain and subcuticular skin closure. It is aimed at elimination of the causative factors of pilonidal sinus. METHOD: The patient's age, profession, weight and height, symptoms and signs, duration of symptoms, previous treatments, operation time and cost, hospital stay, return to normal activity, complications, pathologic and microbiologic examinations, and recurrences were noted. All pilonidal sinus cases except pilonidal abscess and extensive gluteal involvement were treated surgically. The procedure consists of an eccentric, elliptical excision of the affected tissue, mobilization of the flap to the sacrococcygeal fascia and the suturing of its edge to the lateral one. Penrose drains were placed in the first eight (7.14 percent) cases, but suction drains were placed in others. The cases were followed up for a mean of 2.4 years. RESULTS: Twenty-eight (25 percent) cases had undergone previous operative procedures. Of 112 patients 106 (94.6 percent) were male. Mean age was 22.1 years. Mean history of disease was 4.2 years. The overall complication rate was 7.14 percent. Two (1.8 percent) wound infections, two wound breakdowns, three (2.7 percent) collections, and one (0.9 percent) recurrence were recorded. The collections were reduced to zero after first eight cases by using a suction drain. Sixty-eight of the patients (60.7 percent) had body weight over 90 kg, and the mean body mass index was 24.8. The mean hospital stay was 2.6 days, and the mean time off work was 12.4 days. The average healing time was 13.2 days. There were no anesthetic or surgical deaths. CONCLUSION: The natal cleft is flattened and the incision scar and the incision line is transferred from the midline to the lateral side by performing the asymmetric excision and primary closure, and thus the essential cause of pilonidal sinus is eliminated. The procedure is simple, the complications and recurrences are very low, and it is seen to be an excellent procedure in the surgical treatment of uncomplicated pilonidal sinus disease.

Negative pressure pulmonary oedema induced by direct suctioning of endotracheal tube adapter.

PURPOSE: Negative pressure pulmonary oedema (NPPE) is a well-recognized but rare complication secondary to upper airway obstruction such as laryngeal spasm during emergence from general anaesthesia. Cauterization of the second and third thoracic sympathetic ganglia is a treatment for hyperhidrosis of the hands. We report a case of NPPE induced by direct suctioning of the endotracheal tube adapter during thoracic sympathetic ganglionectomy without recognized upper airway obstruction. CLINICAL FEATURES: A 19-yr-old otherwise healthy, non-smoking man was scheduled for elective bilateral chest endoscopic ablation of the second and third thoracic sympathetic ganglion for hyperhidrosis of the hands under general anaesthesia. To view and cauterize the ganglion with the endoscope, the surgeon requested cessation of positive pressure ventilation. As the surgeon could not satisfactorily visualize the target ganglia, he requested brief application of wall suction via the ETT tube adapter. A pressure of -100 mmHg was generated which lasted for three to four seconds. The goal was to reduce further the lung volume by increasing the pneumothorax produced by the endoscope. The patient developed negative pressure pulmonary oedema without upper airway obstruction. CONCLUSION: This case demonstrated that intrathoracic negative pressure generated by direct ETT adapter suctioning may produce pulmonary oedema similar to that induced by laryngeal spasm during the emergence of general anaesthesia.

[The value of wound drainage with or without suction].

Even though the discussion for desisting from wound drainage has arisen, this is not reflected in the reality of surgical treatment. In more than 90% of all procedures wound drainage is used. It remains to be proven whether suction drainage actually is superior to gravity drainage in everyday use. In a random study with 200 patients it was proven that suction drainage shows no significant advantage in liquid quantum, haematoma and the frequency of complications. We conclude that the economically favourable gravity drainage can replace the more expensive suction drainage in most cases.

Nosocomial pneumonia in mechanically ventilated patients, a prospective randomised evaluation of the Stericath closed suctioning system.

OBJECTIVE: To compare the ventilator-associated pneumonia (VAP) incidence rates in mechanically ventilated patients according to the type of endotracheal suctioning (closed versus open). SETTING: The Neurosurgery Intensive Care Unit of the Grenoble University Hospital, France. DESIGN: A prospective randomised study performed after a 6-month period of nursing personnel training. PATIENTS: One hundred four consecutive patients needing mechanical ventilation for more than 48 h were randomised into two groups. To be eligible, patients had to have no active infection or respiratory affection in their passes. In the Stericath group (S+, n = 54), patients were not disconnected from the ventilator during suctioning. The others were routinely managed (S-, n = 50). In both groups patterns of frequency and duration of suctioning were performed according to a standardised protocol. MEASUREMENTS: The non-adjusted incidence rate of VAP was lower for S+ than for S- (7.32 versus 15.89 per 1000 patient-days, p = 0.07). Multivariate analysis performed using the Cox model showed an adjusted risk of VAP 3.5 times higher in S- (95% CI: 11.00-12.33). The risk being 4.3 higher in patients receiving gastric acid secretion inhibitors (1.08-16.82). In non-censored cases (n = 76) length of ICU stay increased by an average of 16.8 days when VAP was present (p = 0.0008). No adverse effect due to Stericath use was noted and volume of tracheal aspirate was similar between groups (p = 0.178). CONCLUSION: The use of Stericath reduced the incidence rate of VAP without demonstrating any adverse effect.

Suction drain tip culture in orthopaedic surgery: a prospective study of 214 clean operations.

We conducted a prospective cohort study in order to determine whether suction drain specimen cultures from orthopaedic surgery predicted an early wound infection. We included 218 consecutive clean orthopaedic operations requiring drains in one unit over a period of 1 year. The suction drain tip, drain fluid and wound discharge specimens were cultured, and the surgical wound was followed up for 3 months. There were six deep and two superficial wound infections. Wound infection was significantly related to positive suction tip culture but not to positive drain fluid culture. Following our methodology for culture, a positive drain tip culture predicts wound infection in 50% and a negative culture virtually excludes the possibility of a deep infection.

Excision with primary closure and suction drainage for pilonidal sinus in adolescent patients.

Controversy persists regarding the treatment of pilonidal sinus (PS). To evaluate the efficacy of excision with primary closure and closed-suction drainage in adolescent patients, between 1990 and 1999, 34 consecutive patients aged 13-18 years (mean 16.4) underwent PS excision with primary closure and suction drainage. Anesthesia was general in 16 (47%) and spinal in 18 (53%) with a statistical age difference ( P< 0.001) (15.5 vs 17.2 years, respectively). No complications due to the anesthetic were observed. Twenty-one patients (61.8%) had day-case surgery while the others were hospitalized for 2 to 4 days (average 2.3 days). The drain was removed on postoperative day 2 to 6 (average 2.2). Primary healing with no postoperative complications occurred in 30 patients (88.2%); 1 underwent partial opening of the wound because of rupture of the drainage tube during its removal. Postoperative infections requiring incision, drainage, and lay-open occurred in 3 cases (9.1%). No recurrence was found at 12-month follow-up. One recurrence (2.9%) was noted 3 years after surgery. Excision with primary closure and closed-suction drainage as an ambulatory procedure is thus a simple and effective method of treatment of uncomplicated PS in adolescents.
