Laparoscopic tubal ligation in a minimally invasive surgical unit under local anesthesia compared to a conventional operating room approach under general anesthesia

Salpingectomy vs tubal ligation for sterilization: a systematic review and meta-analysis

OBJECTIVE

After strong evidence and major organizations recommending salpingectomy over tubal ligation, we sought to perform a systematic review and meta-analysis comparing the intraoperative attributes and complication rates associated with these 2 procedures.

DATA SOURCES

We searched PubMed, the Cochrane Library, Embase, and clinical trials registries without time or language restrictions. The search was conducted in February 2020. Database searches revealed 74 potential studies, of which 11 were examined at the full-text level. Of these, 6 studies were included in the qualitative analysis and 5 studies were included in the meta-analysis.

STUDY ELIGIBILITY CRITERIA

We included randomized controlled trials comparing salpingectomy with tubal ligation in women seeking sterilization. We included studies that also had at least 1 outcome listed in the population/patient problem, intervention, comparison, outcome, and time. Articles were excluded if they did not meet the inclusion criteria or if data were not reported and the authors did not respond to inquiries.

STUDY APPRAISAL AND SYNTHESIS METHODS

Abstracts and full-text articles were assessed by 2 authors independently using the blinded coding assignment function or EPPI-Reviewer 4. Conflicting selections were resolved by consensus. The quality of included studies was determined using the Cochrane Collaboration tool for assessing the risk of bias in randomized trials. Two authors independently assessed the risk of bias for each study; disagreements were resolved by consensus.

RESULTS

There were few differences between the procedures, with no differences in most important clinical outcomes (antimüllerian hormone, blood loss, length of hospital stay, pre- or postoperative complications, or wound infections). A single study reported a reduced rate of pregnancies with salpingectomy (risk ratio, 0.22; 95% confidence interval, 0.05-1.02), but this did not reach statistical significance (P=.05).

CONCLUSION

We conclude from these data that salpingectomy is as safe and efficacious as tubal ligation for sterilization and may be preferred, where appropriate, to reduce the risk of ovarian cancer.

Factors associated with reduced radiation exposure, cost, and technical difficulty of inferior vena cava filter placement and retrieval

We sought to delineate factors of inferior vena cava filter placement associated with increased radiation and cost and difficult subsequent retrieval. In total, 299 procedures from August 2013 to December 2014, 252 in a fluoroscopy suite (FS) and 47 in the operating room (OR), were reviewed for radiation exposure, fluoroscopy time, filter type, and angulation. The number of retrieval devices and fluoroscopy time needed for retrieval were assessed. Multiple linear regression assessed the impact of filter type, procedure location, and patient and procedural variables on radiation dose, fluoroscopy time, and filter angulation. Logistic regression assessed the impact of filter angulation, type, and filtration duration on retrieval difficulty. Access site and filter type had no impact on radiation exposure. However, placement in the OR, compared to the FS, entailed more radiation (156.3 vs 71.4 mGy; P = 0.001), fluoroscopy time (6.1 vs 2.8 min; P < 0.001), and filter angulation (4.8° vs 2.6°; P < 0.001). Angulation was primarily dependent on filter type (P = 0.02), with VenaTech and Denali filters associated with decreased angulation (2.2°, 2.4°) and Option filters associated with greater angulation (4.2°). Filter angulation, but not filter type or filtration duration, predicted cases requiring >1 retrieval device (P < 0.001) and >30 min fluoroscopy time (P = 0.02). Cost savings for placement in the FS vs OR were estimated at $444.50 per case. In conclusion, increased radiation and cost were associated with placement in the OR. Filter angulation independently predicted difficult filter retrieval; angulation was determined by filter type. Performing filter placement in the FS using specific filters may reduce radiation and cost while enabling future retrieval.

Laparoscopic Sterilization Under Local Anesthesia with Conscious Sedation Versus General Anesthesia: Systematic Review of the Literature

Female sterilization is the most popular and common contraceptive method worldwide. Because hysteroscopic sterilization techniques are used less often due to side effects, the number of laparoscopic sterilization is increasing. A systematic overview concerning the most optimal anesthetic technique for laparoscopic sterilization is lacking. We performed a systematic review to compare conscious sedation with general anesthesia for laparoscopic sterilization procedures with respect to clinical relevant outcome measures, such as operating times, perioperative parameters and complications, patient comfort, recovery, and patient satisfaction. We searched Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE for randomized controlled trials comparing general anesthesia with conscious sedation for laparoscopic sterilization. Two authors (AGH and HAAMvV) abstracted and entered data into RevMan. Methodologic quality of the included trials was critically appraised. For our main outcome measures mean differences (continuous variables) and risk ratios (dichotomous variables) with 95% confidence intervals using random-effect models were calculated. Four randomized controlled trials were included comparing general anesthesia versus local anesthesia with conscious sedation for laparoscopic sterilization. The methodologic quality of the studies was moderate to good. Both techniques were comparable with regard to operating times, complications, and postoperative pain. However, local anesthesia with conscious sedation showed better results compared with general anesthesia with respect to recovery times, patient complaints of sore throat, and patient recovery and satisfaction. In conclusion, this systematic review about anesthetic techniques for laparoscopic sterilization showed that both general anesthesia and conscious sedation have no major anesthetic complications and may therefore be safe. Patients might benefit from conscious sedation in terms of recovery times, sore throat, and patient recovery and satisfaction, but only a few studies are included in the review and are relatively old. New research regarding this subject is needed to advise our patients most optimally in the future about the best anesthetic technique to be used when choosing for a laparoscopic sterilization procedure.

Does anesthetic method influence vaginal bulge symptoms and patient satisfaction after vaginal wall repair surgery?

INTRODUCTION AND HYPOTHESIS

Surgery for pelvic organ prolapse (POP) under local anesthesia has been advocated for several reasons such as lower costs and application in multimorbid patients. The aim of this study was to investigate how the anesthetic method influences the rate of recurrent prolapse and patient satisfaction with POP surgery.

METHODS

In this retrospective study 4,936 women operated for single-compartment prolapse between 2006 and 2011 were included from the Swedish National Register for Gynecological Surgery. The feeling of vaginal bulge 1 year after surgery indicated presence of recurrent prolapse. Multivariate logistic regression analyses were used to identify independent factors affecting the outcomes, presented as adjusted odds ratios (aOR) with 95 % confidence interval (CI).

RESULTS

After surgery for single-compartment prolapse patients with cystocele were at a higher risk of feeling a vaginal bulge than patients with rectocele (1.62, CI 1.28-2.06). Applied anesthesia was no independent predictor of bulge symptoms in the cystocele/rectocele population. In the cystocele group local anesthesia compared with general or regional anesthesia implied an increased risk of vaginal bulge symptoms (1.32, CI 1.03-1.68) as well as POP-Q-stage III-IV (1.30, CI 1.09-1.55), and a higher BMI class (1.22, CI 1.03-1.46), while a higher age class decreased the risk (0.79, CI 0.70-0.89). Choice of anesthesia had no impact on bulge symptoms in the rectocele group and no influence on patient satisfaction in any of the groups.

CONCLUSION

Patients operated for cystocele under local anesthesia were at a higher risk of experiencing vaginal bulge symptoms 1 year after surgery compared with general or regional anesthesia.

Regional anesthesia for laparoscopic surgery: a narrative review

Laparoscopic surgery has advanced remarkably in recent years, resulting in reduced morbidity and shorter hospital stay compared with open surgery. Despite challenges from the expanding array of laparoscopic procedures performed with the use of pneumoperitoneum on increasingly sick patients, anesthesia has remained largely unchanged. At present, most laparoscopic operations are usually performed under general anesthesia, except for patients deemed "too sick" for general anesthesia. Recently, however, several large, retrospective studies questioned the widely held belief that general anesthesia is the best anesthetic method for laparoscopic surgery and suggested that regional anesthesia could also be a reasonable choice in certain settings. This narrative review is an attempt to critically summarize current evidence on regional anesthesia for laparoscopic surgery. Because most available data come from large, retrospective studies, large, rigorous, prospective clinical trials comparing regional vs. general anesthesia are needed to evaluate the true value of regional anesthesia in laparoscopic surgery.

Faecal calprotectin: a noninvasive diagnostic tool and marker of severity in pouchitis

INTRODUCTION

In pouchitis, the mucosa is infiltrated by activated polymorphonuclear neutrophils capable of producing calprotectin, a stable antimicrobial myelomonocytic protein.

AIM

The aim is to assess the ability of faecal calprotectin to differentiate between inflamed and noninflamed ileal pouches, and to correlate this with inflammation severity using the newly developed Objective Pouchitis Score.

METHOD

Fifty-four stool samples were collected from patients who had undergone restorative proctocolectomy; 46 from patients with ulcerative colitis and eight from those with familial adenomatous polyposis coli. Faecal calprotectin concentrations were determined by quantitative enzyme-linked immunosorbant assay.

RESULTS

Of the ulcerative colitis patients, six were diagnosed with pouchitis and pre-pouch ileitis (median faecal calprotectin: 865 microg/g, with a range of 95-2350 microg/g); 13 had pouchitis alone (145, 33-3350 microg/g) and 27 were uninflamed (56, 4-705 microg/g). Of the familial adenomatous polyposis patients, one had pouchitis and pre-pouch ileitis (305 microg/g), and seven had noninflamed pouches (9, 6-26 microg/g). Stool samples obtained from pouchitis patients had significantly higher calprotectin concentrations compared with those obtained from uninflamed pouches (Mann-Whitney: P<0.0001). Faecal calprotectin concentrations correlated closely with the Objective Pouchitis Score, the Pouch Disease Activity Index and endoscopic and histological inflammatory scores (Spearman rank test: P values <0.0001). Using a faecal calprotectin threshold of >or=92.5 microg/g to define a positive result, Receiver Operating Characteristic analysis demonstrated a sensitivity of 90% and a specificity of 76.5%.

CONCLUSION

Faecal calprotectin measurement is a useful noninvasive tool in the diagnosis of acutely inflamed ileal pouches and correlates well with the severity of pouchitis.

A randomized trial of local anesthesia with intravenous sedation vs general anesthesia for the vaginal correction of pelvic organ prolapse

The purpose of this study is to compare the feasibility of local anesthesia with IV sedation versus general anesthesia for vaginal correction of pelvic organ prolapse. Patients with pelvic organ prolapse who were scheduled for an anterior or posterior colporrhaphy, or an obliterative procedure, and who did not have a contraindication or preference to type of anesthesia were randomized to one of the two anesthesia groups. Nineteen patients were randomized to the general group and 21 patients were randomized to the local group. Mean operating room, anesthesia, and surgical time were similar in each group, and 10 patients in the local group bypassed the recovery room. Requests and doses of antiemetics, postoperative verbal numerical pain scores and length of hospital stay were similar between the two groups. Mean recovery room and total hospital costs were significantly lower in the local group. Local anesthesia with IV sedation is a feasible alternative for vaginal surgery to correct pelvic organ prolapse.

Systematic review and meta-analysis of interventions for postoperative fatigue

BACKGROUND

Postoperative fatigue is common, even after uncomplicated operations. Various theories have been presented regarding its aetiology, each suggesting different possible interventions. The purpose of this review was to identify all studies that have assessed interventions for postoperative fatigue and to evaluate these interventions using meta-analytical techniques.

METHODS

Randomized controlled trials of interventions, identified from a systematic search of relevant databases, were evaluated according to standardized criteria and categorized according to intervention modality. Data relating to the efficacy of each intervention at four different postoperative time-points were collated and data synthesis by meta-analysis was performed.

RESULTS

Analgesia is effective in reducing fatigue immediately after operation. Perioperative administration of human growth hormone reduces fatigue between 8 and 30 days after abdominal surgery. Weaker evidence was found to suggest an influence of glucocorticoid administration and of surgical technique on fatigue in the first week after operation. No evidence was found to support the theory that psychosocial or nutritional interventions affect the symptom.

CONCLUSION

While the results demonstrate that improved analgesia can attenuate immediate postoperative fatigue in most patient groups, further research is needed to determine whether the efficacy of human growth hormone and glucocorticoids extends beyond abdominal surgery. The paucity of research into cognitive-behavioural, sleep and activity-based interventions also needs to be addressed.

Regional anesthesia for laparoscopy

A variety of laparoscopic procedures can be performed on patients under regional anesthesia. Diagnostic laparoscopy in elective and emergency patients, pain mapping, laparoscopy for infertility, and tubal sterilization are some examples. The key benefits of regional anesthesia include less emesis, less postoperative pain, shorter postoperative stay, improved patient satisfaction, and overall safety. Regional techniques, such as rectus sheath blocks, inguinal blocks, and caudal blocks, are useful adjuncts to general anesthesia and facilitate postoperative analgesia. Other techniques, such as spinal and epidural anesthesia, and combination of the two, are suitable as a sole anesthetic technique for laparoscopy. The physiologic changes during laparoscopy in the awake patient appear to be tolerated well under regional anesthesia. It is reasonable to assume that with advances in instrumentation and surgical techniques, the role of laparoscopy will increase in the future. The benefits conferred by regional anesthesia make it an attractive option to general anesthesia for many patients and procedures. Successful implementation of regional anesthesia is an important determinant of how anesthesiologists, surgeons, and surgical facilities cope with new challenges. In the future, it could be possible to provide "walk-in/walk-out" regional anesthesia with a real possibility of fast tracking patients through the recovery process after ambulatory surgery. For maximal patient safety, however, facilities offering regional anesthesia must have appropriately trained anesthesia personnel and the equipment necessary for monitoring and providing full resuscitation in the event of complications or a need to convert to general anesthesia.
