RESUMEN
Pneumatosis intestinalis is a condition characterized by the presence of gas or air pockets within the walls of the intestines. It can occur in any section of the gastrointestinal tract but it is most commonly found in the colon. Etiology and pathogenesis of PI are not yet fully understood, but several potential factors have been suggested to play a pivotal role in the development of this pathologic condition. Pneumatosis intestinalis seems to arise from a complex interplay between various factors, such as the integrity of the intestinal lining, pressure within the portal vein, the composition of the microbiological flora in the gut. Pneumatosis intestinalis can be caused by a variety of underlying conditions, such as bowel obstruction, intestinal ischemia, infection, inflammatory bowel disease, or certain medications. Symptoms may include abdominal pain, bloating, diarrhea, vomiting, and bloody stools. We present a case report of a 63-year-old male patient who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis with recurrent cholecystitis. Following the surgery, the patient experienced a rapid drop in hemoglobin levels, necessitating an urgency regimen laparoscopic abdominal exploration which revealed Meckel's diverticulitis with active bleeding leading to diverticulectomy. The next day, the patient developed a radiological condition characterized by the co-presence of intermittent pneumatosis intestinalis, Portal pneumatosis and intermittent small bowel obstruction.
RESUMEN
Gastro-intestinal disorders in older patients is a medical emergency that requires immediate medical care. Chances of recovery improve with an early diagnosis and treatment. It might be caused by a number of different diseases, including perforations by foreign bodies, colon cancer, diverticulitis, ischemia. CT is often the initial modality used to assess patients with acute abdomen, the radiologist may be the first to suggest such a diagnosis. Computed tomography allows to identify the site of gastrointestinal perforations, of ischemia and to determine the most predictive signs in this diagnosis. The purpose of this study was to assess the diagnostic performance of CT gastrointestinal emergency of elderly patients with nontraumatic acute abdominal pain. The cases of 126 consecutively registered patients 65 years old or older presenting to the emergency department with acute abdominal pain and who underwent CT were retrospectively reviewed by two radiologists. Diagnostic accuracy was calculated according to the level of correctly classified cases in both the entire cohort and a surgical subgroup and was compared between readings. Agreement between each reading and the reference diagnosis and interobserver agreement were assessed with kappa statistics. In both the entire cohort (87.5% vs 85.3%, p = 0.07) and the surgical group (94% vs 91%, p = 0.15), there was no significant difference in CT accuracy between diagnoses made by the radiologist. Agreement between the CT diagnosis and the final diagnosis was excellent. In the care of elderly patients, CT is accurate for diagnosing the cause of acute abdominal pain, particularly when it is of gastrointestinal surgical origin. Thus CT interpretation should not be delayed until complete clinicobiologic data are available, and the images should be quickly transmitted to the emergency physician so that appropriate therapy can be begun.

Acute appendicitis is the most common cause of acute abdomen requiring emergency surgery. In particular, it affects patients older than 20 years and diagnosis is challenging in this patient subset. The radiologic methods (ultrasound and computed tomography) play a key role in the identification, characterization and staging of the disease as well as optimal timing of surgery. The aim of our study is to assess the usefulness of ultrasound imaging in the diagnosis of acute appendicitis and in a retrospective analysis of 54 ultrasound and computed tomography exams performed in the emergency department.

Authors evaluated the effects of selective adrenergic blockade by means of doxazosin on blood pressure in 48 patients operated on for pheochromocytoma by a multicenter retrospective study. Age, tumor size, surgical approach, and operative time were analyzed as predictive factors of intraoperative hypertensive crises. Forty-eight patients underwent adrenalectomy--four open surgery and 44 laparoscopic surgery--for pheochromocytoma of adrenal glands from 1998 to 2008 after preoperative administration of doxazosin. Perioperative cardiovascular status modifications and surgical medium- and long-term outcomes were analyzed. There was no mortality, conversion rate was 4.5 per cent, and morbidity rate was 8.3 per cent. Intraoperative hypertensive crises (180/90 mmHg or higher) were observed in 14.5 per cent (seven of 48) of patients and were treated pharmacologically with no aftermath. None of the examined variables influenced the occurrence of intraoperative hypertensive episodes. Postoperative hypotension (lower than 90/60 mmHg) was observed in four of 48 patients (8.3%) and was treated by crystalloids and hydrocortisone. In the surgical treatment of pheochromocytoma, the preoperative adrenergic blockade by doxazosin does not prevent intraoperative hypertensive crises. Nevertheless, in our series, they were of short duration and were not associated with major cardiovascular complications. Perioperative hemodynamic instability was managed by preoperative pharmacological treatment, allowing low morbidity.

Metanephric adenoma (MA) is a rare benign tumor, diagnosis of which is often carried out after surgical treatment. In case of peripheral lesions, a partial nephrectomy (PN)--either open or laparoscopic may be preferred--and, furthermore, a radiofrequency (RF)-assisted procedure may facilitate adequate hemostasis. In November 2010, the authors performed a RF-assisted PN, according to Habib's technique, using a 4-needle bipolar device, on a woman affected by a small exophytic MA of the right kidney. Fibrin glue was applied on the cut surface. Postoperative course was uneventful, and discharge was on postoperative day 4. MA is an extremely rare benign tumor with a favorable prognosis. In case of a preoperative cytological diagnosis, a careful follow-up has to be considered. PN represents the standard of care for small exophytic MA, and RF-assisted procedures allow an excellent hemostasis and a rapid conservative resection, with very low morbidity.

BACKGROUND: Thyroidectomy is considered a low-risk operation. The authors report a case of tracheal necrosis after total thyroidectomy for multinodular goiter with bilateral adenomas, and a case of oesophageal fistula after total thyroidectomy for papillary cancer. METHODS AND RESULTS: The patient with tracheal perforation was treated by a non operative management after clinical stabilization. The patient with oesophageal perforation underwent surgical treatment consisting of neck drain placement. Both patients are alive after 12 months of follow-up, although the patient who had surgery for papillary cancer of the thyroid gland was found to have multiple diffuse liver and lung metastases. CONCLUSIONS: Thyroidectomy is a safe surgical procedure, but in some patients major complications may arise. In cases of iatrogenic tracheal or oesophageal perforation, conservative non-surgical or conservative surgical treatment, in specialized centers, results in a favourable outcome. The authors discuss the risk factors and management of these two rare complications.

Splenic abscess is an uncommon but potentially life-threatening disease that generally occurs in patients with neoplasia, immunodeficiency, hemoglobinopathies, trauma, metastatic infection, splenic infarction and diabetes. Splenic abscess should be considered in a patient with fever, left upper abdominal pain, and leukocytosis. Splenectomy has been the gold standard treatment for splenic abscess, however, burdened by high morbidity rate related clinical conditions of the patient. With the recent development of minimally invasive techniques and percutaneous US- or CT-guided procedures, the placement of a drainage has achieved excellent results with resolution of the disease in a high percentage of cases with low morbidity and negligible mortality. Percutaneous drainage is indicated for uniloculated or biloculated abscesses and for high risk surgical patients. It is a reliable technique with a high rate of therapeutical success and low costs compared to surgery. Other advantages include avoiding risks of intra-abdominal spillage and perioperative complications and saving time, along with a better patient compliance and an easier nursing care. The authors describe a case of splenic abscess treated by percutaneous US-guided drainage. Our results suggest that ultrasound-guided percutaneous drainage is a safe and feasible alternative to surgery in the treatment of splenic abscesses. In addition, it allows spleen preservation.

INTRODUCTION: The Authors present their experience with laparoscopic total or subtotal colectomy (TC or SC) in three patients operated for intractable chronic slow transit constipation (STC), together with a review of literature. MATERIAL AND METHODS: From July 2005 to July 2009 three young patients affected by STC, after meticulous preoperative instrumental work-up and after failure of medical treatment, were submitted to laparoscopic TC and ideo rectal anastomosis (IRA) in two cases and to laparo assisted SC followed by Ceco Rectal Anastomosis (CRA) in one case. Number of daily bowel motions, urgency soiling, incontinence, abdominal pain, bloating with special regard to patient's quality of life, were analyzed. RESULTS: All the interventions were completed via laparoscopic approach. No postoperative morbidity or mortality were observed. After twelve months, the patients referred two-three daily evacuation of soft stool, with a good continence and disappearance of abdominal pain and other relatives symptoms. They reported excellent satisfaction with the surgical results and a significant improvement of their quality of life. DISCUSSION: TC with IRA and CRA after SC represent the most effective and widely used surgical operations in the treatment of STC, in well selected patients, after failure of conservative treatment. According to Literature data, and in our experience, no significant differences in terms of postoperative morbidity or mortality neither in quality of life were observed between the two operations. It is well demonstrated the feasibility of the laparoscopic approach in treatment of colorectal pathologies with typically advantages of less invasive surgery, respect of parietal integrity, less postoperative pain and ileus, fewer postoperative adhesions, a reduced hospitalisation and finally a better cosmesis. CONCLUSIONS: Laparoscopic TC and IRA and CRA after laparo assisted SC represent efficacious operations in the treatment of STC offering a good postoperative quality of life and reduced morbidity compared to open surgery.

Tracheal rupture is a rare condition, and its most common cause is head and neck injury. Nontraumatic disruption of the anterolateral fibrocartilaginous trachea is an exceptional complication following thyroidectomy with few cases reported in literature. We report a case of upper tracheal necrosis arising 15 days after uneventful total thyroidectomy and resulted in pneumomediastinum and subcutaneous emphysema. The patient felt a sudden pop in his neck following an episode of vigorous coughing and experienced rapid swelling in his neck. The presence of pneumomediastinum was diagnosed on chest Computed Tomography scan and bronchoscopy visualized a small perforation on the right side of the anterolateral tracheal wall. The first interesting aspect is that several factors (female gender, thyrotoxic goiter, wound infection or excessive use of diathermy) reported as possible cause of anterior tracheal necrosis in the previous reports are unlike for the present case. The second unusual point is the spontaneous healing of the tracheal tear. Considering the no-critical ill condition of the patient and the size of the tear we decide for a conservative treatment rather than surgical repair. Finally, our report underlights that the presence of subcutaneous emphysema following thyroidectomy should alert the possible existence of tracheal rupture. The favourable outcome of our patient shows that small tracheal perforation due to tracheal necrosis may be successfully treated with conservative treatment.

AIM: The authors analyze the short and long-term results of surgical treatment in 70 consecutive patients operated on from for secondary Hyperparathyroidism (2HPT) of chronic kidney disease (CKD). MATERIAL OF STUDY: Seventy patients affected by 2HPT of CKD, in hemodialytic treatment, were observed from January 1999 to January 2009. Twenty-seven patients were submitted to total parathyroidectomy (TP), 36 pts were submitted to total parathyroidectomy plus subcutaneous autoimplantation (TP ai), 7 pts were submitted to subtotal parathyroidectomy (SP). RESULTS: An improvement of the typical clinical symptoms was found in every patient undergoing surgery, and a significant reduction in intact parathyroid hormone (iPTH) serum levels was achieved TP determined a lower incidence of one year relapse. After TPai 9/36 pts successfully underwent renal transplantation. DISCUSSION: To date surgical treatment of 2HPT is still controversial. SP and TPai are the most commonly adopted surgical interventions while TP had been previously been confined to patients with advanced dialytic vintage or for the treatment of recurrence, for the risks arising from aparathyroidism. TP allows a lower long-term relapse incidence and managing the resulting hypoparathyroidism appears straightforward with medical treatment. CONCLUSIONS: The Authors are in favour of early surgical intervention to prevent cardiovascular complications. TPai may be the operation of choice in patients eligible for kidney transplantation while TP carachterized by a lower incidence of long term relapse, is reserved to patients not eligible for transplantation and affected by a more "aggressive" forms of 2HPT.

The RET gene codes for a tyrosine kinase receptor, expressed in neural crest derived cells playing a central role during embryogenesis. The RET proto-oncogene is responsible for medullary thyroid cancer and multiple endocrine neoplasia type 2. To date, more than 50 germline point mutations have been described. A specific correlation between genotype and phenotype is well recognized. Genetic testing is predictive of cancer onset, age at onset and biological aggressiveness. In recent years, the concept of codon-oriented prophylactic surgery has been introduced and three levels of risk have been identified on the basis of specific mutations. A review of the literature shows the excellent results of laboratory, genetic and clinical research that have made it possible to reduce medullary thyroid cancer-related mortality.

Papillary and follicular thyroid carcinoma are still characterised by unclear biological and clinical behaviour with an autoptic incidence higher than the clinical incidence. Lymph-node involvement represents a prognostic factor that may increase the rate of local relapse, reducing long-term survival only in high risk patients--age > 45 years, M+, T > 3 cm, extra thyroidal extension, follicular histotype. The authors analyse the role of lymph-node cervical dissection. Routine or selective, extended or conservative lymphectomy are described in the literature. Prognostic factors are useful to determine the most appropriate surgical procedure. An elective cervical central dissection may be indicated in patients at high risk, while in cases of monolateral lymph-node metastases, in patients at low risk, a selective lymph node dissection of levels VI-III-IV is associated with lower morbidity. Modified radical neck dissection is reserved for patients at high risk or in cases of multiple lymph-node metastases (> 5) to reduce the incidence of local relapse. In the treatment of differentiated thyroid carcinoma an elective total thyroidectomy must be performed in combination with adjuvant radioiodine ablation.

BACKGROUND/AIMS: Laparoscopic cholecystectomy is characterized by a higher incidence of iatrogenic biliary lesions. The Authors evaluate the role of hepaticojejunostomy in the treatment of iatrogenic biliary lesions following laparoscopic cholecystectomy in 51 patients observed in the Campania region, Italy from 1991 to 2003. METHODOLOGY: The Authors report the data of a retrospective multicentric study of 51 patients -39 women (76.47%), 12 men (13.53%)-reoperated on for major biliary lesions following laparoscopic cholecystectomy. Hepaticojejunostomy in 20 cases (39.21%) and T-Tube plasty in 20 cases (39.21%) were performed. RESULTS: The mean follow-up was 25.01 months. The mean hospital stay was 25.7 days. 1/51 patients (1.9%) died from intraoperative incontrollable hemorrhage while cumulative postoperative mortality was 9.8% (5/51 patients). Therapeutic success rate of hepaticojejunostomy was 70% with a T-Tube plasty success rate of 65%. 9/51 patients (17.64%) were reoperated while in 4/51 (7.84%) a biliary stent was positioned. In 1/51 patients (1.9%) a biliary cirrhosis and in 3/51 (5.7%) a bioumoral cholestasis was observed. CONCLUSIONS: Laparoscopic cholecystectomy causes a higher incidence of iatrogenic biliary lesions. Hepaticojejunostomy gives better long-term results and lower morbidity compared to T-Tube plasty. Management of septic complications in patients with iatrogenic biliary lesions represents the first therapeutic step.

Fecal incontinence (FI) is associated to elevated costs related to diagnostic work-up, surgical treatment and instrumental follow-up. The real incidence is unknown and prevalence is higher after 45 years with a ratio F:M ratio of 8:1. Frequently FI is due to pelvic damage secondary to obstetric trauma. The Authors analyze surgical treatment results of FI secondary to obstetric trauma evaluating pathogenesis and instrumental diagnostic preoperative work-up. In case of muscular injury, "overlapping" of external sphincter represents the treatment of choice allowing a good medium long term results. In the treatment of patients with more complex injures or after overlapping failures, direct sphincteroplasty are indicated. After multiple surgical failures, or in case of pure neural damage, sacral nerve stimulation, graciloplasty or artificial anal sphincter may be offered by referral centers.

An higher incidence rate of iatrogenic bile duct injuries is reported in cholecystectomy performed with the laparoscopy than with the laparotomy approach. The aim of this study was to provide a multicentre report on surgical treatment and the outcome of biliary complications during and following laparoscopic cholecystectomy. A questionnaire was mailed to all surgeons with experience in laparoscopic cholecystectomy in the Campania region. Data were collected from January 1991 to December 2003. Each patient was requested to indicate age, gender, associated diseases, site and type of lesion, surgical experience, diagnosis, treatment and complications. Twenty-six surgeons answered the questionnaire. Fifty-one patients (36 F/15 M; mean age: 42.5 +/- 11.9, range 13-91 years) with bile duct injuries following laparoscopic cholecystectomy were reported. The most frequent lesions were main bile duct partial or total transection. The intraoperative mortality rate was 1/51 (1.9%) due to a complex biliary and vascular injury. The postoperative mortality rate of revision surgery was 5/50 (10%). T-tube positioning (n = 20) and Roux-en-Y hepato-jejunostomy (n = 20) were the procedures most frequently performed. The complication rate in patients treated with the T-tube was significantly higher than in those treated with hepatico-jejunostomy. Surgical treatment of biliary injuries following laparoscopic cholecystectomy was characterized by unusually high mortality and morbidity for a non-neoplastic disease. Roux-en-Y hepato-jejunostomy remains the procedure of choice for these injuries.
