Trends in Utilization of Adrenalectomy in the United States: Have Indications Changed?

Minimally invasive approaches have dramatically reduced morbidity associated with adrenalectomy. There has been concern that an increased frequency of adrenal imaging along with the advantages of less morbidity could influence the indications for adrenalectomy. We tested the hypothesis that adrenalectomy has become more common over time and that benign diseases have been increasingly represented among procedural indications. The Nationwide Inpatient Sample (NIS) database was utilized to determine the incidence of adrenalectomy and the associated surgical indications in the United States between 1988 and 2000. All discharged patients were identified whose primary ICD-9-CM procedure code was for adrenalectomy, regardless of the specific surgical approach (laparoscopic adrenalectomy was not reliably coded). This subset was then queried for associated ICD-9-CM diagnostic codes. Linear regression and t-tests were utilized to determine the significance of trends. The total number of adrenalectomies increased significantly, from 12.9 per 100,000 discharges in 1988 to 18.5 per 100,000 discharges in 2000 (p = 0.000003). The total number of adrenalectomies with a primary ICD-9-CM code for malignant adrenal neoplasm did not increase significantly: from 1.2 per 100,000 discharges in 1988 to 1.6 per 100,000 discharges in 2000 (p = 0.47). The total number of adrenalectomies with a primary ICD-9-CM diagnostic code for benign adrenal neoplasm increased significantly, from 2.8 per 100,000 discharges in 1988 to 4.8 per 100,000 discharges in 2000 (p = 0.00002). The average percentage of adrenalectomies performed for malignant neoplasm was significantly higher during the period 1988–1993 when compared to 1994–2000 (11% vs. 9%; p = 0.002). The average percentage of adrenalectomies performed for benign neoplasm was significantly lower during 1988–1993 when compared to 1994–2000 (25% vs. 28%; p = 0.015). Adrenalectomy is being performed with increasing frequency. This is associated with an increase in the proportion of adrenalectomies performed for benign neoplasms. Assuming no significant change in disease prevalence during the study period, these data suggest that indications for adrenalectomy may have changed somewhat over that period.This article was presented at the International Association of Endocrine Surgeons meeting, Uppsala, Sweden, June 14–17, 2004.     

Editorial Commentary: Hip Arthroscopy in the Professional Athlete…Back in the Game

With improved outcomes and expanding indications, the rate of hip arthroscopy for treatment of numerous pathologies has increased. There is significant interest from patients and providers alike regarding return to meaningful play after surgical intervention, particularly for the professional athlete. Although each athlete and each sport have unique obstacles, the literature suggests hip arthroscopy has a high success rate and allows for elite athletes to return to play without significant differences in postoperative performance scores.     

Placement of Inferior Vena Cava Filters in Bariatric Surgical Patients – Possible Indications and Technical Considerations

Background: Surgical treatment of the morbidly obese has assumed an increasingly important role in both the academic and community setting, while postoperative pulmonary embolism remains a devastating complication. Since the overall incidence remains low, the role for vena cava filter placement in this group is not yet well defined. In addition, the technical challenges and techniques for insertion have not been well-described. We present our experience with filter placment among patients with gastric bypass and the evolution of technique to facilitate safe placement in this group. Methods: From 1995 to August 2003, 586 patients underwent gastric bypass for morbid obesity. Review of registries and records from this period was accomplished to identify patients at MUSC who underwent both the gastric bypass and placement of an inferior vena cava filter. 12 patients were identified by this method. Results: Technical challenges with venous access and imaging are described. 6 patients were identified as potential high risk for thromboembolic complications and had a filter placed preoperatively with a mean postoperative stay of 5.3 days. The 6 patients who required filter placement in the postoperative period as part of the management of postoperative complications had a mean hospital stay of 24.5 days. There were no long-term complications associated with filter placement at a mean follow-up interval of 19 months. Conclusion: Inferior vena cava filter placement is not only feasible and safe for the morbidly obese individual undergoing gastric bypass, but should be strongly considered for patients with risk factors for thromboembolic complications or who experience postoperative complications requiring ICU stay or prolonged immobility.     

Editorial Commentary: Total Hip Arthroplasty After Hip Arthroscopy—Solution for the Failed Arthroscopy or a Matter of Pushing the Envelope and Questionable Indications

With the inevitable explosion of arthroscopic hip procedures being performed, the less frequent indications and failures are becoming prevalent enough to analyze. As with any procedure, failures occur and solutions are sought after. “Total hip arthroplasty after prior hip arthroscopy” is a statement that brings to mind several questions and comments. Yes, it is important to evaluate the impact of a prior arthroscopy on eventual total hip arthroplasty outcomes and complication rates. The bigger question when the arthroplasty is performed less than 2 years after hip arthroscopy, however, is “How did we get here?” The pivotal issue at hand might be one of pushing surgical indications a bit too forcefully on multiple fronts. It might be time to return to “Indications 101” to minimize an exponential increase regarding this particular topic with this particular failure timeline.     

Ileo-anal pouch excision and permanent ileostomy – Indications and outcomes from a tertiary centre

PurposePouch excision is a major complication of ileoanal pouch surgery. Current practice is for this type of surgery to be performed in a specialist centre. We present a series of patients undergoing pouch excision surgery in a high volume centre in the UK and assess the outcomes in these patients.MethodsAll patients undergoing pouch excision at the Royal Liverpool Hospital between 1995 and 2015 under the care of a single surgeon were included. Demographics and outcomes were taken from patients' notes and a dedicated retrospectively compiled database.Results35 patients underwent pouch excision surgery during this period. Around half the patients had their original pouch surgery elsewhere and were referred for management of complications. Median time to pouch excision was 13 years from the original operation. Overall complication rate was 31% with 11% requiring re-intervention post-operatively. There was no mortality in this series.ConclusionPouch excision is a complex, high-risk procedure that should be carried out in specialist centres. Our series shows that in such settings, good outcomes can be achieved for these patients.

Elective splenectomy in the elderly – perioperative and long-term course

BACKGROUND: The hazards of elective splenectomy in the elderly have not been thoroughly investigated. The aim was to assess such a well-defined cohort with respect to perioperative and long-term outcome. METHODS: Fifty-two consecutively splenectomised patients during the period 1971-1995, aged 65 years or older, were followed until death (44 cases) or the end of 1999 (8 cases). RESULTS: No intraoperative deaths occurred, while three patients (5.8%) died postoperatively in the 1970s. Twenty-four patients suffered from thirty-four postoperative complications, dominated by infections and haematomas. No differences were seen comparing patients with and without complications related to the American Society of Anesthesiologists' classes, total transfusion rate, steroid medication, preoperative risk diseases, "giant spleens" or the time period during which the operations were performed. In 69% of the patients, the splenectomy was beneficial. During the long-term follow-up, 25 patients suffered from 59 infectious and thromboembolic episodes and 1 surgical complication. The dominating causes of death were the primary disease (29%), myocardial infarction (20%), sepsis (12%) and cerebrovascular lesions (12%), i.e. not directly related to late effects of the operation. CONCLUSION: High-risk patients older than 65 years with haematological disorders can safely undergo splenectomy with a low mortality rate and a reasonable rate of morbidity. The long-term course demonstrates a fair response rate, minimal surgically related complications, but thromboembolic and infectious events, and the majority of deaths unrelated to late effects of the splenectomy.     

Editorial Commentary: On Mentors and “Peeling Onions”: Scoliosis Results in Inferior Outcomes Following Hip Gluteus Medius Tendon Repair

Scoliosis results in improved but inferior outcomes following gluteus medius repair. The hip is affected by lumbo-pelvic position and gravity, and the disorder is predominant in women and perhaps also related to pelvic morphology. Numerous opportunities for future study exist.     

Editorial Commentary: How Far Can the Arthroscope Reach in the Ankle Joint?

Surgical access to pathology of the talar dome (e.g., osteochondral lesions of the talus) can be limited because of the ankle joint congruity. When considering arthroscopic treatment, anterior arthroscopy with the ankle in plantar flexion or posterior arthroscopy with the ankle in dorsiflexion is used. The surgeon should carefully assess different clinical and radiologic aspects to plan the optimal operative approach. Meticulous physical examination, including ankle range of motion and possible palpation of a talar lesion, in combination with exact lesion localization on computed tomography or magnetic resonance imaging usually provide sufficient preoperative information. Most lesions with the anterior border localized on or anterior to the midline of the talus are accessible by anterior arthroscopy. In the case of preoperative doubt concerning the intraoperative accessibility, a computed tomography scan of the ankle in full plantarflexion is used to mirror arthroscopic reachability. Intraoperative surgical tricks to increase accessibility to the lesion may consist of an adjunct soft-tissue distraction device, reduction of the distal tibial rim, and treating the lesion from anteriorly to posteriorly, thereby gaining further exposure to the lesion throughout the procedure.     

Bypass – Surgery and Coil – Embolisation in the Treatment of Cerebral Giant Aneurysms

Summary  Objective. Operative clipping is the most effective method in the treatment of cerebral giant aneurysms. But about 50% of all giant aneurysms are treatable this way. We want to report about eight patients with giant cerebral aneurysms, which were in our opinion “unclippable” without causing ischaemia in depending brain areas.  Methods. We describe eight cases of giant aneurysms of the pericallosal artery (n=1), the middle cerebral artery (n=3), the basilar tip (n=3) and of the upper part of the basilar artery (n=1). One patient with an aneurysm of the pericallosal artery was treated with an extra-intracranial saphenous vein bypass saphenous bypass, in three cases of middle cerebral artery aneurysms an extra-intracranial bypass was also done combined with a resection of the aneurysm. The four patients suffering from an aneurysm of the basilar artery got an extra intracranial bypass too followed by an occlusion of the aneurysm with GD-Coils.  Results. There was no peri-operative mortality and no severe peri- or postoperative complication. The neurological symptoms of all patients were unchanged after the operation. An angiographic controll showed a complete obliteration of the aneurysm and a free running bypass in all cases.  Conclusion. Bypass surgery and combined bypass surgery and coil embolisation are effective methods in the treatment of giant cerebral aneurysms, which can not be treated by clipping alone.
