ABSTRACT

OBJECTIVE: The ongoing pandemic of coronavirus disease 2019 is having a dramatic effect on most medical disciplines. Otolaryngology Head and Neck Surgery is one of the most engaged disciplines, and otolaryngology specialists are facing a radical change of their role and daily activities that will have severe impact on the return to the ordinary. In this paper, the COVID-19 Task Force of the Young Otolaryngologists of the Italian Society of Otolaryngology comment on the changes that occurred for otolaryngology in Italy during the pandemic. Changes include organizational rearrangement of Otolaryngology Units, with merges and closures that affected a significant portion of them; reallocation of otolaryngology personnel, mainly to COVID-19 wards; reduction of elective clinical and surgical activity, that was mainly limited to oncology and emergency procedures; and execution of screening procedures for SARS-CoV-2 among healthcare providers and patients in otolaryngology units in Italy.

ABSTRACT

Residual or recurrent laryngeal cancer after irradiation is a difficult clinical problem with a rate that ranges from 13% to 36% of cases. Supracricoid laryngectomy (SCL) with cricohyoidopexy (CHP) or cricohyoidoepiglottopexy (CHEP) provide reliable oncological and functional results for selected primary and recurrent patients with glottic and supraglottic carcinomas. We conducted a systematic review and meta-analysis to assess the oncological and functional outcomes of patients treated with open partial horizontal laryngectomy types IIa and IIb (CHEP, CHP) in terms of the recurrence of squamocellular cancer of the larynx after radiotherapy failure. The databases searched included MEDLINE, PubMed and EMBASE (from January 1990 to December 2015, English language). The meta-analysis was performed with a mixed random effects model using the DerSimonian and Laird method. The heterogeneity was measured with the I2 statistic. Fourteen papers out of 276 were included and comprised a total of 291 patients. The five-year overall survival was 80.2% (CI 0.719-0.885; I2 = 62%; p = 0.003), and the 5-year disease-free survival was 89.5% (CI 0.838-0.952; I2 = 52%; p = 0.022). The indications for SCL after the failure of radiation therapy (RT) were similar to those specified for previously untreated patients. We therefore hypothesised that careful assessment of tumour extension might be responsible for the high 5-year OS and 5-year DFS. The early postoperative recovery outcomes indicated that the mean time until decannulation was 35.6 days (CI 24.3-46.9; I2 = 95%; p < 0.001), and the mean time until nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG) removal was 28.3 days (CI 22.7-33.8; I2 = 86%; p< = 0.001). These data are according to authors who prefer the initial removal of the NGT and the initiation of oral alimentation with a tracheostomy tube to protect and clean the airways and permit the suction of any residual food that might be present.

ABSTRACT

The purpose of this study was to evaluate the oncological and functional outcomes in patients who underwent supracricoid laryngectomies with a crico-hyoidopexy (SCL-CHP) or a crico-hyoido-epiglottopexy (SCL-CHEP) for the treatment of primary and reccurent laryngeal cancer. A retrospective study was conducted on 152 consecutive patients seen from January 1996 to December 2006. Overall survival (OS) and disease-free survival (DFS) were analysed using the Kaplan-Meier method, and were compared according to the type of surgery and clinical stage of the tumour. The mean period before decannulation, nasogastric tube (NGT) removal and recovery of a normal diet and speech were evaluated, and statistical analyses were performed regarding the association with the type of surgery and arytenoidectomy. The median follow-up period was 49.9 months (range: 10-110 months). The 3- and 5-year OS were 87.5 and 83.5%, respectively, and 3- and 5-year DFS were 78.3 and 73.7%, respectively. For patients with early stages tumours, the 5-year OS and DFS were 92.3 and 84.6% respectively, whereas for patients with locally advanced stage tumours, the OS and DFS were 74.3 and 62.2%, respectively. Significant differences in OS and DFS for patients who had early or locally advanced cancers were found (p = 0.0004 and p = 0.0032, respectively). The rate of overall local control was 92.1%, while the mean period until decannulation or NGT removal was 25.1 and 16.6 days, respectively. The mean period until NGT removal was significantly different according to the type of surgery (p = 0.0001) and whether arytenoidectomy was performed (p = 0.0001). The reliable oncological and functional results of SCL for early and locally advanced laryngeal cancers are confirmed by our series of patients.

ABSTRACT

AIM OF THE STUDY: We intended to use a radioguided technique for pre-operative localization of neck node recurrences in patients with papillary thyroid cancer (PTC) already submitted to thyroidectomy and radioiodine treatment. PATIENTS AND METHODS: We selected 20 patients affected by PTC with evidence of neck nodes recurrences at ultrasound examination. Our method has been derived from the Radioguided Occult Lesion Localization technique used for pre-operative localization of occult breast lesions. The technique involves the inoculation of human albumin macroaggregates labeled with radioactive technetium (0.4 mCi in a volume of 0.05 ml) directly in the suspicious lesion, under ultrasound guidance. The persistence of the radioactive tracer in the nodes is confirmed by a scintigraphy performed 2 h after injection. During surgery, a gamma detecting probe is used to locate the suspicious lesions as "hot spots". RESULTS: Fifty lymph-nodes were injected with the tracer. All radiolabeled lymph-nodes were located and removed during surgery. At histology, metastasis of PTC was confirmed in 38/50 (76%) lymph-nodes. At least one metastatic lymph-node per patient was removed. In 8/20 (40%) patients, reactive lymphoid hyperplasia was found in 12/50 (24%) lymph-nodes. CONCLUSIONS: This radioguided technique has been highly effective for localization and surgical treatment of suspicious lymph-node detected at neck ultrasound and may play a valuable role in case of node metastases of thyroid cancer that show no radioiodine uptake.

ABSTRACT

Cystic fibrosis (CF) is mainly caused by small deletions or missense mutations in the CFTR gene. The CF mutation database lists more than 35 large rearrangements that may escape detection using polymerase chain reaction-base techniques. The Innogenetics assay, the denaturing high-performance liquid chromatography and sequencing screening showed a mutation detection rate of 92.6% in our population. We report here the results of multiplex ligation-dependent probe amplification (MLPA) screening for CFTR gene rearrangements, performed on the unidentified alleles of our CF patients. Our sample population consists of 692 non-related Italian CF patients (for a total of 1384 alleles), followed at CF Centres in the Lombardia Region. MLPA analysis was performed in 49 patients who still had one or two unidentified alleles (for a total of 52 unidentified alleles) after extensive analysis of CFTR gene. All patients who were studied had the classical form of CF. We characterized nine different deletions and a new duplication. The deletion of exons 22-23 (7/82) was the most frequent in our cohort. The search for deletion/duplications of the CFTR gene has made it possible to reach a 94.1% detection rate, with an improvement (1.6%) of the carrier detection rate in the Italian population.

ABSTRACT

AIM: The risks of specific complications of the laparoscopic technique, caused by pneumoperitoneum and by insertion of the first trocar, although rare, are frequently reported in literature. METHODS: A retrospective study of the complications we had in the period from October 1998 to December 2006 was made on 2700 patients who did not need any trocars in the umbilicus or with scars due to previous surgery, who were treated with a particular technique of pneumoperitoneum induction and the insertion of the first trocar, named ''Open Veress Assisted'' (OVA). RESULTS: We had two visceral complications (0,07%) (ileal perforations). CONCLUSION: Although no surgical technique is without risks, we believe that the use of our technique is safer than a blind insertion of the first trocar, especially among the patients with scars due to previous surgery.

ABSTRACT

BACKGROUND: We report our experience with laparoscopic adrenalectomy (LA) for malignant pathologies that in some cases required a multiorgan resection. METHODS: In this study, we retrospectively reviewed a group of 15 patients (10 men, and five women) who underwent an operation for primitive or metastatic adrenal malignant tumors. RESULTS: The sizes of the lesions ranged from 3.5 to 8.5 cm (average 3.6). We performed 11 adrenalectomies (four right and seven left), two left adrenalectomies with distal spleno-pancreatectomy, one right adrenalectomy with nephrectomy, and one laparoscopic exploration that showed a peritoneal spreading. Six patients, with a follow-up ranging from 3 to 24 months (mean 13.6 months), are disease free; the others developed metastatic repetitions or local recurrences. CONCLUSIONS: LA could be performed always respecting the oncological principles of radical excisions. This approach in our patients has been associated with low morbidity, low intraoperative blood loss, short hospital stay, and fast functional recovery.

ABSTRACT

The use of an intrauterine contraceptive device (IUD) is often accompanied by various complications, the perforation of the uterus constituting the most dangerous. Here we report the case of a patient who complained of abdominal pains. She had had an IUD inserted 15 months previously. Three months later, as she could no longer see the IUD strings at the external os of the cervix, she underwent pelvic ultrasonography, which did not show the IUD in the uterine cavity. A diagnosis of expulsion of the IUD was made. A few months later, the patient accidentally became pregnant, and decided to have an abortion. From that time on, she started to complain of the above-mentioned symptoms. She had an abdominal X-ray which revealed the IUD in the abdominal cavity. She then underwent a laparoscopic removal of the translocated IUD.

ABSTRACT

We report here our experience in the treatment of a large congenital diaphragmatic hernia, an uncommon pathology, approachable by laparoscopy. The patient was a 33-year-old woman with trisomy 21 syndrome, who only complained of colicky abdominal pain and a cough for 7 months before the hospitalization. Thoracic and abdominal CT scans showed a large anteromedial diaphragmatic hernia with slippage of the colon into the mediastinum and posterior displacement of the cardiovascular structures. The patient underwent laparoscopic repair of the hernia. The colon was put back in the abdomen; the defect (8x4 cm) was repaired by a Composix mesh (PTFE-polypropylene), fixed to the diaphragm by nonabsorbable stitches and staples. The patient was discharged on the third postoperative day. The postoperative course was uneventful. Follow-up at 18 months didn't show any complications or recurrence. We believe laparoscopic repair of diaphragmatic hernia to be the elective surgical choice, because of its technical feasibility and certain intra- and postoperative advantages.

ABSTRACT

BACKGROUND: Some reports have suggested that laparoscopic splenectomy (LS) can be successfully performed in adults. However, several aspects of this procedure remain as yet undefined; therefore, several attempts have been made to modify the standard technique to try to optimize the procedure. Herein we analyze our experience with 105 laparoscopic splenectomies. METHODS: From 1993 to 2000, 105 patients underwent LS at our hospital. Twelve of these patients also underwent a concomitant cholecystectomy. There were 66 women and 39 men whose ages ranged between 4 and 78 years (median, 27.7). All patients underwent an elective laparoscopic splenectomy. Seventy five patients had thrombocytopenia (ITP), 14 had hereditary spherocytosis, eight were affected by b-thalassemia, two had splenic cysts, two had lymphoma, (two had myeloid chronic leukemia, one patient presented with a splenic abscess and one had incurred an iatrogenic spleen lesion during adrenalectomy. The first patients in this series were positioned in dorsal decubitus; however, as the team's experience increased, the right lateral decubitus became the position of choice because it provides better exposure of the splenic hilum. This procedure requires the use of only four trocars. RESULTS: Mean operating time was 95 min (range, 35-320). Hospital stay ranged from 2 to 21 days (median, 4.5). There was only one conversion to open surgery. One patient died in the postoperative period due to the evolution of a preexisting malignant disease. We recorded nine complications-four subphrenic abscesses, two cases of pleuritis, two episodes of postoperative bleeding, and one intestinal infarction 16 days after surgery. Only two patients needed redo surgery. CONCLUSIONS: We believe that the laparoscopic approach is a valid alternative to open splenectomy, but mastery of some of the technical details of this procedure could greatly help avoid its complications. On the basis of our experience, it seems that the lateral approach should be considered the position of choice because it provides exposure and easier dissection of the splenic hilar structures. We also found that a 30 degrees scope and an ultrasonic dissector allowed for perfect vision and optimal hemostasis during the procedure. At the end of procedure, the spleen should be fragmented and then extracted using an extraction bag.

ABSTRACT

BACKGROUND: The acceptability of the classic laparoscopic technique in the treatment of acute appendicitis is slow, probably due to the higher costs of this method compared to the cheaper, efficacious, safe and rapid discharge associated with traditional surgery. METHODS: In order to combine the advantages of the laparoscopic technique with those of traditional surgery, we performed a retrospective study of the safety, efficacy, rapid discharge with return to normal working activities, and the costs in 70 patients referred to our attention with a diagnosis of acute appendicitis and who underwent one trocar appendectomy. This technique consists of positioning a single trocar in an umbilical site and using a 10 mm telecamera with a 5 mm operating canal. Having visualised the appendix and freed it from any synechiae, the distal end is grasped and it is removed through the umbilical trocar. Appendectomy is performed outside using a technique that is similar to traditional surgery. The diagnosis of acute appendicitis was made on the basis of clinical data (pain, leucocytosis, fever, possible resistance in the right iliac fossa).

ABSTRACT

Two cases of endometriosis infiltrating the round ligament and associated with an inguinal hernia are presented. The initial diagnosis was irreducible hernia, since this rare association often causes unusual preoperative symptoms and diagnostic problems. Diagnosis is frequently made by histologic examination. Surgery is the treatment of choice both for hernia and for endometriosis, and is locally curative. However, in a fertile woman with a painful mass in the inguinal region the possibility of endometriosis should be considered, and if suspected at inguinal exploration a laparoscopy should be made to rule out the presence of intraperitoneal endometriosis.

ABSTRACT

BACKGROUND: The usual treatment of blunt aortic injury (BAI) is prompt surgery. Frequently severe injuries to the brain or lungs exclude further surgical treatment. The purpose of this study is to assess the feasibility of placing endovascular stent-grafts. METHODS: From 1992 through 1999, in our primary and referral trauma center, 26 acute BAI, 21 males and 5 females, mean age 40.2+/-16.3 yrs were diagnosed. The last 4 patients underwent prospectively endovascular repair with Talent endograft. Endoprosthesis parameters were measured on three-dimensional spiral CT reconstruction. While waiting for devices, blood pressure was aggressively lowered and aortic lesions were monitored by transesophageal echography. RESULTS: Stent-graft deployment was successful in all 4 patients. There were no complications of endoleak, stent migration, paraplegia or death. Angiographic exclusion was complete in all 4 patients. CT scans at a mean follow-up of 11+/-5 months showed complete healing of the aortic wall in all patients. CONCLUSIONS: For stable acute BAI, endovascular stent-graft repair is feasible and safe, and is an effective therapeutic alternative to open surgery. Because of the normal proximal and distal wall in aortic injuries, endoluminal treatment might be the therapy of choice in the near future.

ABSTRACT

Percutaneous nephrostomy (NP) is a routinely applied procedure in adults, but sparsely reported in the pediatric population. We report the treatment of acute obstructive renal diseases in 15 children aged one day to 6 years. The causes of obstruction included pelvi-ureteral junction stenosis (10 cases) by calculus or complicated by pyonephrosis, vesico-ureteral junction stenosis (2 cases), urethral valves and stenosis (2 cases) and one complex urogenital malformation. Catheter placement was performed under ultrasonographic guidance without immediate complication. NP should be considered as a primary preoperative modality for urinary tract obstruction in the pediatric population.

ABSTRACT

In western European countries most blunt chest traumas are associated with motor vehicle and sport-related accidents. In Switzerland, 39 of 10,000 inhabitants were involved and severely injured in road accidents in 1998. Fifty two percent of them suffered from blunt chest trauma. According to the Swiss Federal Office of Statistics, traumas represented in men the fourth major cause of death (4%) after cardiovascular disease (38%), cancer (28%), and respiratory disease (7%) in 1998. The outcome of chest trauma patients is determined mainly by the severity of the lesions, the prompt appropriate treatment delivered on the scene of the accident, the time needed to transport the patient to a trauma center, and the immediate recognition of the lesions by a trained emergency team. Other determining factors include age as well as coexisting cardiac, pulmonary, and renal diseases. Our purpose was to review the wide spectrum of pathologies related to blunt chest trauma involving the chest wall, pleura, lungs, trachea and bronchi, aorta, aortic arch vessels, and diaphragm. A particular focus on the diagnostic impact of CT is demonstrated.

ABSTRACT

Pelvic varices of the gonadal veins affect both males and females presenting as varicoceles in the former and utero-ovarian varices in the latter. These varices are frequently encountered in the general population and can be directly associated with a significant morbidity. The affected venous axes can be easily catheterized in a selective, retrograde manner and can then be occluded through this minimally invasive route, thus avoiding the major surgical complications while giving results comparable or superior to those of the various surgical techniques. These pathologic processes and their endovascular treatment will be discussed.

ABSTRACT

This work monitors the radiation doses to a radiologist during supervision of automatic contrast media injections during helical-CT examinations of the chest and abdomen. Forty consecutive standard helical-CT examinations of adult's chest and/or abdomen were monitored with five dosimeters worn by the radiologist supervising the entire injection with the hand on the injection site. Mean doses per examination measured at chest, thyroid gland, and hand levels were 11, 16, and 130 microGy, respectively, during chest examinations, and 5, 7, and 55 microGy during abdominal examinations. According to the high number of CT examinations performed, wearing lead apron, special lead glove protection, and thyroid shield is highly recommended.

ABSTRACT

Pulmonary edema may be classified as increased hydrostatic pressure edema, permeability edema with diffuse alveolar damage (DAD), permeability edema without DAD, or mixed edema. Pulmonary edema has variable manifestations. Postobstructive pulmonary edema typically manifests radiologically as septal lines, peribronchial cuffing, and, in more severe cases, central alveolar edema. Pulmonary edema with chronic pulmonary embolism manifests as sharply demarcated areas of increased ground-glass attenuation. Pulmonary edema with veno-occlusive disease manifests as large pulmonary arteries, diffuse interstitial edema with numerous Kerley lines, peribronchial cuffing, and a dilated right ventricle. Stage 1 near drowning pulmonary edema manifests as Kerley lines, peribronchial cuffing, and patchy, perihilar alveolar areas of airspace consolidation; stage 2 and 3 lesions are radiologically nonspecific. Pulmonary edema following administration of cytokines demonstrates bilateral, symmetric interstitial edema with thickened septal lines. High-altitude pulmonary edema usually manifests as central interstitial edema associated with peribronchial cuffing, ill-defined vessels, and patchy airspace consolidation. Neurogenic pulmonary edema manifests as bilateral, rather homogeneous airspace consolidations that predominate at the apices in about 50% of cases. Reperfusion pulmonary edema usually demonstrates heterogeneous airspace consolidations that predominate in the areas distal to the recanalized vessels. Postreduction pulmonary edema manifests as mild airspace consolidation involving the ipsilateral lung, whereas pulmonary edema due to air embolism initially demonstrates interstitial edema followed by bilateral, peripheral alveolar areas of increased opacity that predominate at the lung bases. Familiarity with the spectrum of radiologic findings in pulmonary edema from various causes will often help narrow the differential diagnosis.
