P-POSSUM score: a prognostic instrument for postoperative complications in Crohn's disease.

AIM: The purpose of this work is to demonstrate the correlation between the p-POSSUM score and the severity of Crohn's Disease (CD) postoperative complications, evaluated by using the Clavien-Dindo score. PATIENTS AND METHODS: We have selected data of 22 patients (11 males, 11 females) that had been recovered in the Operative Unit of General Surgery of the University of Palermo General Hospital and undergone surgery for CD from 2010 to 2017. RESULTS: Patients who underwent surgery for complicated CD was divided in three different group on the base of Clavien Dindo score, C1 (Clavien-Dindo ≤ 1), C2 (Clavien Dindo = 2), and C3 (Clavien Dindo ≥ 3). ANOVA one way statistic analysis was used to investigate the presence of statistic difference in the mean of p-POSSUM operative score between the three groups of patients who underwent surgery for complicated CD. Results show that the severity of postoperative complication after surgery for complicated CD is related to the value of p-POSSUM score (p = 0,004965). CONCLUSIONS: This study clearly demonstrates a statistic correlation between p-POSSUM operative score and the risk of occurrence of severe postoperative complications in patients with Crohn's disease that had been undergone to surgical procedures of resection with ileostomy and percutaneous drainage.

Long-term esophageal motility changes after thyroidectomy: associations with aerodigestive disorders.

BACKGROUND: Patients undergoing thyroidectomy often complain aerodigestive disorders. In a previous study we showed the associations between voice impairment and proximal acid reflux, swallowing impairment and Upper Esophageal Sphyncter (UES) incoordination and the decrease in UES pressure in thirty-six patients observed before and soon afterwards uncomplicated thyroidectomy. This study investigated the state of post-thyroidectomy esophageal motility changes and its associations with these disorders after 18-24 months. PATIENTS AND METHODS: The thirty-six patients prospectively recruited according to selection criteria (thyroid volume ≤60 ml, benign disease, age 18-65 years, previous neck surgery, thyroiditis, pre- or postoperative vocal cord palsy) underwent voice (VIS) and swallowing (SIS) impairment scores, esophageal manometry and pH monitoring once again. RESULTS: After 18-24 months, both VIS and SIS recovered (respectively: p=0,022; p=0,0001); UES pressure increased (p=0,0001) nearing the preoperative values. The persistence of swallowing complaints were associated with the persistence of esophageal incoordination (p=0,03); the association between voice impairment and proximal acid reflux was confirmed (p<0,001). CONCLUSIONS: Our study confirms that aerodigestive disorders after uncomplicated thyroidectomy, largely transient, are strictly connected with upper esophageal motility changes. In this viewpoint, the innervation of upper aerodigestive anatomical structures (larynx, pharynx, upper esophagus) and its variations should be focused.

The coexistence of primary hyperparathyroidism and thyroid nodules: should the preoperative work-up of the parathyroid and the thyroid diseases be specifically adjusted?

INTRODUCTION AND OBJECTIVES: Primary hyperparathyroidism (PHPT) can be found in concomitance with thyroid disease (TD) in a high frequency of cases. In this context the diagnostic exams for localizing the enlarged parathyroid(s) gland(s) could be less reliable or nonconclusive. Moreover, the thyroid carcinoma seems to be more frequent compared to that isolated thyroid desease and, therefore, carefully investigated. The main goal of the present study is to evaluate which diagnostic tool (US, MIBI) is more reliable for localizing the site of the PTH hypersecretion and to confirm if it is always advantageous a combination of both exams. Besides, we evaluated the incidence of thyroid carcinoma in our series of patients. PATIENTS AND METHODS: A review of available data of 73 patients who underwent total thyroidectomy + parathyroidectomy from 2003 and 2014 was performed. The preoperative workup included systematically US and MIBI whose results were considered true positive when at least the side (left/right) of the parathyroid affected were concordant with the surgical report, settled as the gold standard, according to the Cox nonnested model. The connection between the diagnostic results of US versus MIBI was calculated with the Cohen K index for evaluating their overlap. The average of the thyroid carcinoma were also calculated. RESULTS: The difference between respectively US versus surgical report (p value=0.73) and MIBI versus surgical report (p value=0.81) were not significant. The low Cohen K index showed that both US and MIBI are complementary. In 23 patients (32,9%) a thyroid carcinoma was found. CONCLUSIONS: The association of MIBI and neck US is mandatory in the first evaluation of patients undergoing thyroidectomy and parathyroid excision simultaneously. The high prevalence of thyroid carcinoma in this specific context suggests a more aggressive diagnostic and surgical behaviour.

Comparison of minimally invasive parathyroidectomy under local anaesthesia and minimally invasive video-assisted parathyroidectomy for primary hyperparathyroidism: a cost analysis.

BACKGROUND: Primary hyperparathyroidism (PHPT) origins from a solitary adenoma in 70- 95% of cases. Moreover, the advances in methods for localizing an abnormal parathyroid gland made minimally invasive techniques more prominent. This study presents a micro-cost analysis of two parathyroidectomy techniques. PATIENTS AND METHODS: 72 consecutive patients who underwent minimally invasive parathyroidectomy, video-assisted (MIVAP, group A, 52 patients) or "open" under local anaesthesia (OMIP, group B, 20 patients) for PHPT were reviewed. Operating room, consumable, anaesthesia, maintenance costs, equipment depreciation and surgeons/anaesthesiologists fees were evaluated. The patient's satisfaction and the rate of conversion to conventional parathyroidectomy were investigated. T-Student's, Kolmogorov-Smirnov tests and Odds Ratio were used for statistical analysis. RESULTS: 1 patient of the group A and 2 of the group B were excluded from the cost analysis because of the conversion to the conventional technique. Concerning the remnant patients, the overall average costs were: for Operative Room, 1186,69 € for the MIVAP group (51 patients) and 836,11 € for the OMIP group (p<0,001); for the Team, 122,93 € (group A) and 90,02 € (group B) (p<0,001); the other operative costs were 1388,32 € (group A) and 928,23 € (group B) (p<0,001). The patient's satisfaction was very strongly in favour of the group B (Odds Ratio 20,5 with a 95% confidence interval). CONCLUSIONS: MIVAP is more expensive compared to the "open" parathyroidectomy under local anaesthesia due to the costs of general anaesthesia and the longer operative time. Moreover, the patients generally prefer the local anaesthesia. Nevertheless, the rate of conversion to the conventional parathyroidectomy was relevant in the group of the local anaesthesia compared to the MIVAP, since the latter allows a four-gland exploration.

Large retroperitoneal abscess extended to the inferior right limb secondary to a perforated ileal Crohn's disease: the importance of the multidisciplinary approach.

The typical complications of Crohn's disease concerns small and large bowel. The full thickness inflammation of the intestinal wall develops in strictures, fistulas and abdominal abscesses. Nowadays the most accepted therapeutic for intra-abdominal abscess option is antibiotic therapy and, in case of need, percutaneous drainage of the abscess. If the abscess passes through the pelvic foramen the abscess can involve the inferior limbs. We report a case a perforation of terminal ileum in Crohn's disease complicated by a large abscess of the right iliac fossa reaching the spaces between the anterior lateral muscles of the right thigh as far as the anterior lateral pre-tibial region. We discuss the diagnostic and therapeutic options in a multidisciplinary context.
