Ileal intussusception due to intestinal metastases from primary malignant melanoma of the lung
No full textPrimary malignant melanoma of the lung (PMML) is an uncommon tumor with very few cases reported in the literature that satisfy the required criteria to establish a primary bronchial origin. We report a case of a 44-year-old man with acute abdominal distress and a right pulmonary roentgenographic opacity. A cranial-thoracic-abdominal CT scan confirmed the presence of a pulmonary nodule with bilateral cerebral metastases and marked dilatation of intestinal loops. At laparotomy an ileal intussusception was noted and an ileal resection was done. The resected intestinal segment contained three endoluminal polypoidal formations. Histological and immunohistochemical analyses showed the presence of multiple sites of melanoma. These lesions as well as the brain lesions clearly appeared metastatic. The patient underwent further evaluation to identify a primary site of melanoma; bronchoscopy was performed with biopsy of the pulmonary nodule. Pathology revealed a neoplastic process of fusiform cells, with focal presence of melanic inter- and extracellular pigment. The immunohistochemical analysis confirmed the diagnosis of PMML. We discuss the criteria for diagnosis and histogenesis of PMML along with this unusual presentation
Perineal pilonidal sinus. Case report.
No full textPilonidal sinus is a very common disease and its most frequent location is in the presacral area. Other locations are extremely rare. We describe the case of a 28-year-old white man, a baker by profession, with a swelling around the right side of the anus, pain with burning, itching and seropurulent secretion which had been present for 7 months. A physical examination demonstrated the presence of multiple cutaneous fistulas. A fistulography and the endoscopy demonstrated the absence of fistulas-in-ano. Moreover, MRI confirmed the diagnosis of a perianal mass not communicating with the anal canal. Surgical exploration revealed the presence of hair and an excision of the mass with fistulas was performed. Healing was rapid and uncomplicated. Perineal pilonidal sinus with foreign body inflammatory reaction was the histological diagnosis
Diffuse neuroendocrine tumor of the small bowel: an exceptional case with long survival and literature review
No full textMalignant tumors of the small intestine are uncommon. Carcinoid tumors represent 20% of all malignancies occurring in this segment. We report the case of a 53-year-old female who was treated surgically for intestinal obstruction secondary to carcinoid tumors diffuse to the small intestine. This is the first case described in the literature. Carcinoids are considered less aggressive than the more common intestinal adenocarcinomas, but because of the extensive localization of the neoplasm this case can be considered a high-grade malignancy with an aggressive pattern of growth. Surgical resection, although noncurative in this case, can provide the patient with a long survival rate and a good quality of life
Microsurgical treatment of varicocele in outpatients using the subinguinal approach.
No full textBACKGROUND: The aim of this study is to analyze the results of a group of patients who underwent subinguinal microsurgical varicocelectomy using local anaesthesia in one-day-surgery. METHODS: From 1997 to 1998 150 patients were selected from the whole group of patients who underwent surgical treatment for varicocele. The varicocele was always on the left side and the mean age was 27.1 years (range: 16-43). The diagnosis was based on clinical features (testicular pain or scrotal sensation), physical examination and Doppler ultrasound. Where there was infertility with abnormal semen analysis and/or patient's intolerance to the symptoms, surgery was suggested. The patients underwent varicocelectomy by sub-inguinal approach using local anaesthesia. The microsurgical technique of dissection was performed. RESULTS: All operations were performed on an outpatient basis (post-operative stay: 3-7 hours) and the operating time was 20 to 45 minutes. Follow-up was performed by physical examination, doppler ultrasound and semen analysis. Immediate and long-term complications were: 7 (4.7%) transient pain, 3 (2.0%) ecchymosis, 1 (0.7%) transient hydroceles and 1 (0.7%) permanent hydroceles, 2 (1.3%) palpable recurrence, 2(1.3%) doppler recurrence and 1 (0.7%) long-term recurrence, 0 testicular atrophy. 120/150 (80%) patients showed an improvement of semen analysis and 19/41 (46.3%) patients with infertility achieved a pregnancy with the partner. CONCLUSIONS: Microsurgical treatment of varicocele in outpatients by subinguinal approach is a safe and reliable procedure. It is performed in local anaesthesia, preserves the lymphatics, spermatic artery and vas and in our experience showed an improvement of semen analysis and pregnancy rates with minimal morbidity
Rectal perforations. Personal experience and literature review.
No full textBACKGROUND: Rectal perforation presents high morbidity and mortality and its treatment is still not standardized, it is still rather based on the surgeon's personal experience. This retrospective trial, with a literature review, aims to define these types of lesions, and tries to identify the diagnostic and therapeutic options able to reduce related morbidity and mortality. METHODS: On 1175 operations conducted for colo-rectal emergency, over a ten-year period at our institution, fourteen consecutive patients (1.2%) were seen and treated for rectal perforation. In 43% of cases the treatment consisted in Hartmann's procedure, in the 28.5% ones in rectal wound repair with diverting colostomy and in 28.5% left in diverting colostomy alone. RESULTS: There were no postoperative complications in 86% of patients, and no deaths from sepsis. In 28.5% of cases intestinal continuity was restored at our institution. CONCLUSIONS: Our results demonstrate that a standardized protocol which is based on patients' conditions, type and degree of rectal injury and of peritonitis, must be followed in order to determine the type of surgical option and consequently to reduce the morbidity and mortality related to rectal perforation
[Correlation between chronic obstructive bronchial disease and colonic anastomosis dehiscence in the elderly]. FT Correlazioni tra broncopatia cronica ostruttiva e deiscenza dell'anastomosi colica in eta geriatrica.
No full textBACKGROUND: Anastomotic leakage remains a major complication after large bowel surgery. Chronic obstructive pulmonary disease is frequent disease in the elderly. AIMS: The authors want to analyze the correlation between systemic tissue hypoxia, resulting from chronic obstructive pulmonary disease and anastomotic leakage in large bowel surgery in a group of patients over 65 years. PATIENTS AND METHODS: In the period 1979-2001 at our surgical Department, 590 patients underwent colorectal surgery; 211 elderly patients (> 65 years) with large bowel anastomosis were selected. In 29/211 (13.7%) chronic obstructive pulmonary disease was diagnosed. The group of patients affected by chronic obstructive pulmonary disease was defined as group A; the other, as group B. The incidence of anastomotic leakage in patients with and without chronic obstructive pulmonary disease was evaluated. RESULTS: The overall incidence of anastomotic leakage was 5.6% (12/211); a difference in the incidence of anastomotic leakage was found in the group A vs. B: 7/29 (24.1 %) in the group A were affected by dehiscence vs. 5/182 (2.7%) of group B. This difference was statistically significant (p = 0.001). CONCLUSIONS: Chronic obstructive pulmonary disease can be a factor increasing the risk of anastomotic leakage. The elderly patient is often affected by chronic obstructive pulmonary disease and consequently show an higher risk of colonic anastomotic failure than younger patients

An unusual complication resulting from surgical treatment of periampullary tumours
No full textBackground and methods. The authors describe the rising of four postoperative pancreatic pseudocysts in a series of 20 patients treated for periampullary tumours by pancreaticoduodenectomy (PDT), with the closure of pancreatic stump, between 1989-1996, The operation was always performed by the pylorus-preserving technique according to Traverso-Longmire. Results, In four patients (20%) 3, 4, 4, and 8 months after PDT with closure of the pancreatic stump, the authors observed the development of pseudocysts (PPC) in the pancreatic remnant. All these patients previously had a pancreatic fistula, Three symptomatic patients underwent surgical drainage of the pseudocyst in a jejunal loop (2) or in the stomach (1); in the asymptomatic patient, the clinical feature and the size of the cyst allowed for conservative treatment. In 2 cases PPC was the consequence of a pancreatic fistula evolved in acute pancreatitis of the stump. The PPC drained by cystogastrostomy appeared 4 months after the closure of the pancreatic fistula: the pancreatic stump was completely substituted by a cyst presenting a communication with the pancreatic duct, Conclusions. The authors conclude that PPC is a rare complication of the pancreatic resection that results from acute or chronic pancreatitis; sometimes pathogenesis is due to a cyst resulting from the pancreatic duct occlusion by phlogistic tissue as a consequence of the surgical suture
