Predictors of short term treatment outcome in patients with achalasia following endoscopic or surgical therapy

Pneumatic balloon dilation and surgical myotomy are the most effective treatments for achalasia. While there is controversy which method is best, the aim of the current study was to identify predictors of symptom recurrence after endoscopic or surgical therapy.

Impact of surgical technique on operative morbidity and its socioeconomic benefit in thyroid surgery

The aim of this retrospective cohort study was to evaluate the rate of complications in relation to the extent of surgery and some of its consequences.

Three-dimensional vision enhances task performance independently of the surgical method

Within the next few years, the medical industry will launch increasingly affordable three-dimensional (3D) vision systems for the operating room (OR). This study aimed to evaluate the effect of two-dimensional (2D) and 3D visualization on surgical skills and task performance.

A 10-year longitudinal analysis of surgical management for acute ischemic colitis

Our objective was to review our 10-year experience of surgical resection for acute ischemic colitis (IC) and to assess the predictive value of previously reported risk-stratification methods.

Development of a postsurgical patient-reported outcome instrument for women with vulvar neoplasia

To (a) develop the Women With Vulvar Neoplasia-Patient-Reported Outcome (WOMAN-PRO) instrument as a measure of women's post-vulvar surgery symptom experience and informational needs, (b) examine its content validity, (c) describe modifications based on pilot testing, and (d) examine the content validity of the revised instrument.

Accidental entrapment of an endo-bronchial blocker tip by a surgical stapler during selective ventilation for lung lobectomy in a dog

OBJECTIVE: To describe the use of an endobronchial blocker (EBB) and to perform selective ventilation during pulmonary lobe resection via thoracotomy in a dog and report its accidental stapling in the resection site. STUDY DESIGN: Clinical case report. ANIMAL: One female dog with a suspected abscess or neoplasia of the right caudal pulmonary lobe. METHODS: One-lung ventilation was performed using a wire-guided EBB to seal the contaminated parenchyma and facilitate surgical access. The affected lung parenchyma was resected and the resection site was closed with staples. RESULTS: Lobar resection was performed successfully, but the loop of the EBB guide wire was inadvertently entrapped in the staple line of the lobectomy. Staples were removed to release the wire loop, and the resulting air leak caused loss of ventilation control until the parenchyma was re-sealed. CONCLUSIONS: We recommend removing the wire guide associate with the EBB after successful lung separation to avoid accidents that could have life-threatening consequences if not recognized. CLINICAL RELEVANCE: One-lung ventilation is useful to isolate healthy parenchyma from diseased parenchyma during lobectomy. Anesthesiologists and surgeons need to be aware of the potential complications associated with use of EBB.

Multiple meningiomas: clinical, radiological, surgical, and pathological findings with outcome in four cats

The present report describes the clinical signs, magnetic resonance imaging (MRI) findings, surgical procedure, pathological findings and follow-up in four cats with multiple meningiomas; three castrated male and one spayed female domestic shorthair indoor cats, ranging in age from 11 to 14 years. In three of four cats, clinical signs at presentation were suggestive of a focal lesion. Three cats had two meningiomas and one had four meningiomas. Most of the tumours were supratentorial, one arose from the tentorium and one was infratentorial. The duration of presenting signs before surgery ranged from 10 days to 11 months. Postoperative MRI revealed complete gross tumour removal in three cases. In one cat with two cranial fossa meningiomas, subtotal excision with a small basal remnant (2 x 2 mm) of the ventral part of one meningioma lying on the floor of the skull, was observed. Based on histopathological architecture, six tumours revealed features of a transitional subtype meningioma, and four of a meningotheliomatous meningioma. In each cat, the multiple meningiomas were all assigned to the same histopathological group. The preoperative presenting signs had resolved by the follow-up examinations 4 weeks after surgery in two cats. Long-term follow-up evaluation revealed that surgically-induced or exacerbated neurological deficits in two cats had completely or almost completely resolved within 8 weeks of surgery. All patients are still alive 12 to 21 months after surgery and no clinical signs of recurrence could be detected at that time.

Surgical approach for tentorial meningiomas in cats: a review of six cases

The surgical technique for removal of tentorial meningiomas is described on six cats using a unilateral temporal supracerebellar transtentorial approach. Complete gross tumour resection was achieved in four of six cats. In one cat, only subtotal resection was achieved. One cat died shortly after surgery because of extensive cerebral haemorrhage. The surgical approach, combined with cisternal or ventricular cerebrospinal fluid puncture and an open-window technique (tumour fenestration and enucleation) provided sufficient visibility and tumour accessibility without excessive manipulation of the brain parenchyma. In all patients, a postoperative transient worsening of the clinical signs was observed. The neurological signs resolved with time with the exception of blindness in two cats. All five surviving cats were monitored for a mean follow-up time of 19 months (median 20 months; range 6-30 months). All patients died or were euthanased because of tumour regrowth within the follow-up period. Although challenging, surgical treatment is a useful therapeutic measure in the treatment of cats presenting with tentorial meningiomas.
