[Aortic dissection: role of the general surgeon in diagnostic-therapeutic procedure].

Aortic dissection occurs when there is a tear or separation of the aortic intima from the media; flow of blood into the intima-media space allows the tear to develop into a dissecting hematoma. Aortic dissection is a rare condition which represents an acute cardiovascular emergency for which the appropriate therapy is immediate surgical correction. Patients with aortic dissection show a heterogeneous constellation of symptoms; hence, clinical suspicion is often difficult. Only a minority of patients has "classic" symptomatology, the electrocardiogram is often misleading and the chest radiogram is almost always non-specific. In Italy, the usual "hospital routine practice" assigns the key-role in the emergency diagnostic procedure for these patients to the general surgeon. In view of the necessity of immediate cardiac surgery and the overwhelming likelihood of adverse events when surgery is delayed, techniques for diagnosis must be accurate, widely available and easily and quickly used. The present study consists of four case-reports of aortic dissection thoroughly examined and confronted with the literature. Management strategy based on emergency echocardiography is a reliable, feasible and successful technique for evaluating patients with aortic dissection. It allows a rapid accurate diagnosis with a single examination that can also be performed in the emergency room and provides information of sufficient diagnostic value to allow immediate cardiovascular surgery. CT scan and/or MRI are also valid tools for the emergency diagnosis of aortic dissection. However, a major problem still exists: the range of symptoms is sufficiently broad that a high index of "personal suspicion" of aortic dissection is required on the part of the general surgeon when he performs the role of "emergency-team leader".

[Adenocarcinoma of the duodenojejunal flexure. A report of 2 clinical cases and a review of the literature].

The authors report two cases of adenocarcinoma of the duodenojejunal angle and remark the rarity of this pathology, the difficulty of making diagnosis peculiar to neoplasm of the small intestine and the difficulty of treatment peculiar to tumours of the duodenum. According to the literature the diagnosis was determined through X-ray films, after traditional endoscopy was inadequate. Surgical treatment is radical, with extensive exeresis procedures (unless the mesenteric upper vessels are infiltrated) since the prognosis of this tumours is good.

[Mesh repair of inguinal and femoral hernia].

The authors describe a 6-year experience with mesh repair of inguinal and femoral hernia in a surgical teaching department. Two hundred and ninety-seven hernioplasties were performed in 256 consecutive patients: 237 Trabucco sutureless and 11 Lichtenstein tension-free hernioplasties for inguinal hernia; 21 tension-free hernioplasties for femoral hernia; 20 Wantz GPRVS and 8 Rutkow tension-free hernioplaties for recurrences. Local anaesthesia was used in 59% of cases. Seventy-two patients (28.1%) refused this type of anaesthesia. The hospital stay was two days in all cases. The local postoperative morbidity rate was 8.7% (wound infections: 1.0%; neuralgia: 1.3%; haematomas: 2.0%; seromas: 2.3%; no testicular atrophies). The recurrence rate was 1.9% in the group of patients undergoing surgery from 1994 to 1997 (103 herniorrhaphies; follow-up: 3-6 years) and 0% in the group of patients operated on after 1997 (170 herniorrhaphies; follow-up: 2 years-6 months). The results confirm that the use of a prosthetic mesh (patch and plug) is the treatment of choice for hernia repair. Moreover, this experience in a surgical teaching department shows that these procedures can be safely and effectively performed by all surgeons.

[Therapeutic strategy in symptomatic diverticular disease of the colon].

Diverticular disease of the colon has been recorded with increasing frequency and approximately 25-30% of symptomatic patients require surgery for complications. Controversy still surrounds the best operative approach for the management of diverticular disease, particularly when it presents with complications. The three-stage operation has, for the most part, been abandoned because of its unacceptably high morbidity and mortality rates. Today it is generally believed that performing two-stage surgery is a wise decision, namely segmentary resection either without (Hartmann's procedure) or with anastomosis, protected by a covering colostomy. However, the ideal intervention is a one-stage surgical procedure (segmentary resection and primary anastomosis without a covering colostomy), but this can only be performed in selected patients. The aim of this study was to analyse the clinical course and the medical and surgical therapy retrospectively in 79 patients with symptomatic diverticular disease in order to identify the best therapeutic procedure; specifically, the severity of septic complications was evaluated using Hinchey's classification. The authors conclude that most patients with symptomatic diverticular disease require specific medical therapy. If surgical treatment is necessary (complicated diverticular disease), Hartmann's procedure is still a valid surgical option, particularly in the presence of diffuse faecal peritonitis. Colonic resection and primary anastomosis are certainly a satisfactory treatment, because of their low morbidity and mortality rates, but this surgical approach is only feasible in selected patients. Finally, it is a matter for the individual surgeon's experience to select the best surgical procedure in any particular situation, depending on age and general state, local findings and the extent of peritonitis.

[Prognostic value of C reactive protein in acute pancreatitis].

Controversy still exists regarding the clinical features of acute pancreatitis: it is not known whether this is a disease which progresses from mild to severe forms or which arises immediately as severe acute pancreatitis. An early diagnosis, however, is regarded as mandatory for successful treatment. Over the years many Authors have proposed different scoring systems for the early assessment of the clinical evolution of acute pancreatitis. The most widely used scoring systems (Ranson, Osborne, Apache II) are often cumbersome and difficult to use in clinical practice because of their multifactorial nature. Thus, a number of unifactorial prognostic indices have been employed in routine hospital practice, such as C-reactive protein, serum amylase and serum lipase. These serum enzymes are easy to obtain in normal clinical practice and many authors consider them as reliable as multifactorial scoring systems. One hundred and five patients affected by acute pancreatitis have been hospitalised in the Surgical Department of San Giacomo Hospital (Rome) over an nine-year period. All patients underwent C-reactive protein, amylase, and lipase serum assays on days 1, 3 and 5 after admission. The results show that C-reactive protein assay is highly sensitive in detecting necrotic forms of acute pancreatitis. The authors conclude that C-reactive protein, together with both serum amylase and serum lipase, often provides a precise picture of the clinical situation in patients with acute pancreatitis. On this basis the best therapeutic option can be chosen.

[Intestinal infarction. Retrospective clinical study].

Acute mesenteric ischaemia is the result of inadequate blood flow to all or part of the small intestine and the right half of the colon. Irrespective of the cause of the ischaemic insult, the end results are similar, namely, a spectrum of bowel injury ranging from completely reversible alterations of bowel function to transmural haemorrhagic necrosis of the intestinal wall. Depending on the degree of ischaemia and the length of bowel involved, a wide variety of clinical presentations are observed. Mesenteric infarction is a pathology which is encountered fairly often in elderly patients where the concomitance of other diseases make its prognosis more severe, especially since the diagnosis is usually late. The pessimism expressed more than 70 years ago concerning this disease is still shared by many physicians today. The authors report on their experience with 37 cases of mesenteric infarction. The median age of the patients was 77 years (range: 66-91). The mortality rate was 67.5% (25 deaths) which is in line with the results in the literature. The median hospital stay was 17 days (range: 10-71). The authors emphasise the difficulty of diagnosing and treating this entity, also in view of the fact that, in most centres, it is impossible to perform emergency selective angiography of the superior mesenteric artery. The need for an early specific diagnosis is stressed, because the therapeutic options may vary widely in relation to the different causes of acute intestinal ischaemia.

[Multicenter prospective study of informed consent in general surgery].

To understand the level of acceptance, awareness and usefulness of informed consent, a group of 119 patients (59 men and 60 women) from different types of hospitals were given a questionnaire which required only 'YES or NO' answers, both before and after surgery. The questionnaire concerned the patient's knowledge about pathology, operative risks, approval, anxiety caused, understanding of information received and consent given, and also if he would inform a relative in the same condition. From the analysis of the results it was established that: the more information a patient has about his illness and operation risks, the more he will want to have; the less he knows the less he will want to know, and he will also have more faith in the doctors. Some patients would not inform a relative with a similar pathology. To conclude, informed consent, instead of being a right of the patient is progressively becoming more a right of the doctor. It does not have any real effect on the patient's choice but is useful, as it represents a moment of personalised attention from medical personnel, though the patient may not completely understand the information received. There are few advantages in strictly medical terms but informed consent has increased malpractice litigation.

[Non-palpable lesions of the breast: retrospective clinical study].

A non-palpable breast lesion (NPBL) is a disease of the mammary gland that cannot be detected during clinical examination but that can be visualized by mammography and/or ultrasonography, either during screening programs or sometimes in asymptomatic women. These small lesions require an adequate diagnostic-therapeutic approach to ensure correct treatment. The aim of the present study was to analyse a series of NPBLs retrospectively in order to define them nosologically and establish an adequate diagnostic-therapeutic work-up for such cases. Ninety-three patients with a total of 99 NPBLs were observed from January 1989 to December 1999. The 99 NPBLs were submitted to ultrasonography and 31 (31.3%) were also submitted to US-guided fine needle aspiration biopsy (FNAB). Later on the diagnostic-therapeutic procedure involved surgical biopsy after radiological centering and, in the case of malignant neoplastic lesions, surgical intervention and adjuvant therapy. Ultrasonography confirmed the presence of NPBL in 45 cases of the 99 detected at mammography (45.4%). Cytological examination of the 31 FNABs yielded the following results: unreliable 19.3%, suspected malignancy 42%, negative for neoplastic cytology 6.5%, positive for carcinoma 32.3%. The histological diagnosis was one of mammary carcinoma in 41 patients (43%). Among the 41 carcinomas there were 8 (19.5%) carcinomas in situ, 24 (58.5%) invasive ductal carcinomas, 8 (19.5%) invasive lobular carcinomas, and 1 (2.5%) medullary carcinoma. In the 32 (80%) patients submitted to lymphadenectomy for 33 invasive carcinomas, 6 patients (18.7%) presented positive lymph nodes (N1). The Authors conclude that NPBLs are an important clinical entity because they may be the expression of a malignant lesion; most NPBLs are diagnosed during screening programs or sometimes in asymptomatic women by means of mammography, which is the only standardised method for their identification. The poor diagnostic capability of non-invasive methods and the potential malignancy of NPBL justify the indication for surgical excisional biopsies; in cases of histological findings of malignancy it is often possible to perform conservative surgery with similar results to radical surgery in terms of survival. When NPBLs turn out to be invasive carcinomas, a concomitant lymphadenectomy is mandatory.

[Surgical treatment in acute cholecystitis emergencies].

The aim of the study was to demonstrate the importance of early laparoscopic cholecystectomy for acute cholecystitis, without "conservative" treatment (intravenous fluids and antibiotics for 48-72 hours) to reduce inflammation. Early laparoscopic cholecystectomy reduces bile duct injury and the percentage of conversion to open cholecystectomy. Thirty-five patients with acute cholecystitis were submitted to early laparoscopic cholecystectomy, equally divided according to sex. All patients were submitted to US scans preoperatively and operated on by surgeons skilled in emergency laparoscopic operative techniques. Laparoscopic cholecystectomy was always performed with 4 trochars and the use of a 30 degrees laparoscope. Technical modifications during early laparoscopic cholecystectomy were drainage and decompression with subsequent de-tension and distention of the gallbladder. These manoeuvres entailed the use of Babcock, Endopatch (Ethicon) atraumatic forceps. In the presence of acute gallbladder inflammation we dissect the gall-blader well with a suction-irrigation tube. In patients suspected of having common bile duct stones, biliary duct injuries and/or anatomical changes due to inflammation, we perform intraoperative cholangiography. Five patients had conversion to open cholecystectomy (14.2%), in two cases (5.7%) for concomitant choledochal stones, in two cases (5.7%) for biliary peritonitis and in the fifth case (2.8%) for severe empyema of the gallbladder. Laparoscopic cholecystectomy was performed in 20 patients for acute cholecystitis (57.1%), in 9 patients for empyema (25.7%) and in 6 patients for gangrenous cholecystitis. Four cases presented postoperative complications owing to bile leakage from the liver bed, treated with antibiotic therapy. One patient presented jaundice on day 30 after laparoscopy owing to inadequate positioning of the clips on the cystic duct, near the common bile duct; ERCP was performed with application of a prosthesis, which was removed after two months. Our experience and results support the validity of early laparoscopic cholecystectomy in the treatment of acute cholecystitis, because it reduces the postoperative length of hospital stay and hospital costs. Early treatment is always helpful for inflamed and oedematous tissue which favours dissection, while dense, fibrotic adhesions hinder regular dissection with a greater risk of injury to the biliary duct and and a higher conversion rate to open cholecystectomy.

[Cholecystectomy via video laparoscopy: the whys of a choice].

The management of calculous disease of the gallbladder has undergone significant change during the last decade. Recent years have seen the development of alternative methods for the treatment of biliary stones including dissolution therapy, endoscopic and percutaneous extraction, extracorporeal shock wave lithotripsy. Yet, despite these technologic advances, most surgeons have continued to consider cholecystectomy the safest, most effective and the only curative procedure. Open cholecystectomy, performed in the same fashion for more than a century has demonstrated low morbidity and minimal mortality rates. However, the operation does incur sizable expense in terms of hospitalization, cosmetic appearance and time lost from work. Laparoscopic cholecystectomy quickly emerged as an alternative to open cholecystectomy. The authors report their experience of laparoscopic cholecystectomy performed at the Surgical Department of Montecchio Maggiore Hospital (VI). Twenty-eight patients were operated on: in all but one laparoscopic cholecystectomy was successfully completed; in one case a fistula between gallbladder and the common bile duct led to T-tube drainage insertion via a laparotomy. In one patient laparoscopic cholecystectomy was performed after an endoscopic retrograde cholangio-sphincterotomy for associated stones of the common bile duct. Mean operative time was 69 minutes (range 46-210). Morbidity and mortality were 0%; maximal hospital stay was 48 hours. These data confirm that laparoscopic cholecystectomy may be considered the treatment of choice for stone disease of the gallbladder and it should enter into the cultural and technical background of a general surgeon.

[Ambulatory treatment of postphlebitic ulcers of lower limbs. Physiopathological bases and clinical results].

Venous ulceration is a troublesome and disabling complication, representing one of the most difficult problems to be treated by the vascular surgeon. Venous insufficiency is a widespread condition, the prevalence of venous ulceration being 0.5 - 1 per cent in European populations. Although all venous ulcers will heal if the limb is elevated above heart level for an extended period of time, patients need a safe, effective, not disabling and quick therapy. Hence, the competent vascular surgeon must be familiar with venous pathophysiology and possess a thorough understanding of the treatment options available for a discouraged patient in need of an acceptable and effective approach. The aim of the present study was to assess the efficacy and the speed of healing of venous ulcer using an outpatient ambulatory treatment protocol. This protocol consisted of elastic compression bandage allowing deambulation, local dressing using lyophilized heterologous collagen (Condress, Gentili) and systemic profibrinolytic drugs. Exclusion criteria were coexisting arterial insufficiency, ulcer area greater than 25 cm2, coexisting disabling diseases (congestive cardiac failure, hepatic insufficiency, malignancy). From December 1990 to June 1993, 37 patients affected by venous ulcer were treated, according to the aforementioned protocol, at the Surgical Department of Montecchio Maggiore Hospital (VI). There were 16 male and 21 female patients, mean age was 66 years (range 59-91). Results show the complete healing of the venous ulcer in 94.5% of patients; mean time for ulcer healing was 128 days (range 45-91). The Authors conclude that the outpatient ambulatory treatment protocol is safe, quick, and effective for the therapy of chronic venous ulcer; once obtained the healing of the ulcer, elastic compressive bandage with elastic stockings is mandatory to prevent recurrences.
