RESUMO

Fewer studies compared the improvement of plasma lipid levels after different types of surgery, in particular compared to one-anastomosis gastric bypass (OAGB). The aim of our study was to investigate how laparoscopic sleeve gastrectomy (LSG) and OAGB impact on weight loss and lipid profile 18 months after surgery, in patients with severe obesity. Forty-six patients treated with OAGB were matched to eighty-eight patients submitted to LSG. Weight loss after OAGB (33.2%) was more evident than after LSG (29.6%) (p = 0.024). The difference in the prevalence of dyslipidemia showed a statistically significant reduction only after OAGB (61% versus 22%, p < 0.001). After adjustment for delta body mass index (BMI), age and sex, we demonstrated a statistically significant decrease of the differences between the changes before and after (delta Δ) the two surgery procedures: Δ total cholesterol values (p < 0.001), Δ low density lipoprotein-cholesterol values (p < 0.001) and Δ triglycerides values (p = 0.007). Patients with severe obesity undergoing to OAGB presented a better improvement of lipid plasma values than LSG patients. The reduction of lipid plasma levels was independent of the significant decrease of BMI after surgery, of age and of sex.

RESUMO

The aim of this study was to evaluate the impact of applying strict selection criteria to patients with symptoms of obstructed defecation, rectocele and rectal prolapse who were candidates for surgery. From June 2001 to September 2003, 20 patients underwent surgery in our clinic for symptomatic rectocele and anorectal prolapse. They were evaluated prospectively using a dedicated questionnaire (KESS), a proctological and gynaecological examination, colpo-cysto-defecography and anorectal manometry before surgery and 6 months postoperatively. Strict selection criteria were used for surgery. After 6 months the questionnaire showed an important improvement in symptoms. The symptoms of obstructed defecation and vaginal bulging improved significantly. The average KESS score dropped from 17.65 preoperatively to 5.8 six months after surgery. In the treatment of pelvic floor disease, it is important to evaluate both the uro-gynaecological and the proctological symptoms with the utmost care, obtaining an accurate clinical picture with the aid of dedicated questionnaires and a thorough clinical examination. Evaluation of the effectiveness of surgery for constipation necessarily includes assessing the strength of the indications for surgery, irrespective of the surgical technique adopted, but there is currently no standardised test method for recording and comparing the symptoms of constipation.

RESUMO

BACKGROUND: We undertook this study to evaluate early surgical complications and long-term results after preoperative radiotherapy and chemotherapy (RCT) using 5-fluorouracil (5-FU) and oxaliplatin (OXA) for rectal cancer. METHODS: Forty six TNM stage II-III rectal cancer patients were studied, who were given preoperative RT (50.4 Gy/28 fractions) combined with 5-FU (200-225 mg/m(2)/day by continuous venous infusion) and weekly OXA (25-60 mg/m(2)). Major complications and reoperations were recorded overall, whereas outcome analyses were performed only for patients who received the recommended regimen dosage. RESULTS: Forty three patients (M:F, 25:18; median age 59 years) were available for analysis. All patients received the planned RT dose. There were no postoperative deaths; seven patients had early major surgical complications, four requiring re-operation. One additional patient had a second surgical procedure due to a duodenal fistula complicating the resection of an aortic aneurysm performed concomitantly with rectal cancer surgery. At a median follow-up of 49 months, two of the 23 patients treated at the recommended doses developed recurrence (one local, and one local and distant), and two died of cancer progression. Following the Kaplan-Meier method, the estimated 5-year overall and disease-free survival rates were 92 and 89%, respectively. CONCLUSIONS: The preoperative RCT regimen used in the present study incurs a low rate of recurrence with an acceptable surgical morbidity.

RESUMO

Colitis cystica profunda is a rare intestinal lesion. Because of its clinical expression (rectorrhagia, mucorrhea and abdominal pain) and the way it appears to current imaging techniques this disease presents features which can be associated with colon neoplasm. Its diagnosis has to be confirmed histologically, and its etiology remains unclear. The following is a case report of colitis cystica profunda recurring 20 years after a first episode in a white woman, who had had an anterior resection of the sigmoid colon and upper rectum to deal with a colitis cystica profunda-induced stenosis of the sigmoid colon and at 41 underwent the transanal removal of a polypoid lesion. A review of 20 cases in the literature showed that colitis cystica profunda has a predilection for the male and generally affects the medial and lower rectum and the sigmoid colon. The literature also confirmed the association with ulcerative rectocolitis, Crohn's disease and rectal prolapse. The type of treatment varies from surgical, medical, and endoscopic to no treatment at all.

RESUMO

The use of totally implantable prolonged venous access devices (TIPVAD) in chemotherapy for oncological patients is now consolidated practice, whereas the choice between surgical cutdown and the percutaneous technique is still a controversial matter. The aim of this study was to retrospectively evaluate the validity and safety of the surgical approach by comparison with percutaneous techniques. Over a period of 17 months, 106 patients (mainly oncological cases) underwent surgical cutdown for TIPVAD placement in the cephalic vein. During a mean follow-up of 8 months (range 1-21), we evaluated the surgical and management complications and compared them with reported results obtained with the percutaneous technique. We observed a lower incidence of pneumothorax, 2 cases of malfunction due to kinking, and no catheter fractures, while management complications were similar to the findings in the literature. In expert hands, the surgical approach is a fast, safe technique with a lower rate of intraoperative complications than the percutaneous approach and less discomfort for the patient. Adequate training of medical and paramedical staff is the most important factor in making TIPVAD reliable and safe in the long term.

RESUMO

The stapler treatment first described by Longo is considered by some authors to be a good technical solution for mucohaemorrhoidectomy. The aim of the present prospective study was to assess the function and morphology of the internal and external anal sphincters preoperatively and one month after surgery by means of a clinical examination, anorectal manometry and transperineal ultrasound. Ten patients (6 M, 4 F) underwent rectal mucosal prolapsectomy according to Longo. Anoscopy, anorectal manometry and transperineal ultrasound were performed in all patients preoperatively and again one month after surgery. The thickness and integrity of the internal and external anal sphincters were ascertained and colour Doppler was performed to assess the presence, quantity and size of any haemorrhoid swellings. All anatomical specimens underwent histological examination in search of smooth muscle fibres. Anorectal manometry revealed no postoperative sphincter tone defects. Transperineal ultrasound detected no postoperative sphincter lesions and the presence of venous swellings (always present at preoperative colour Doppler) never persisted at postoperative follow-up. The mean follow-up was 52.7 days (range: 31-151). Transperineal ultrasound proved useful in demonstrating the lifting of the mucohaemorrhoid prolapse within the ampulla of the rectum one month after surgery. The Longo procedure, in our albeit limited experience, caused no sphincter lesions.

RESUMO

Giant condyloma acuminatum of the anorectum (Buschke-Lowenstein tumour) is a rare interesting infectious disease caused by the papillomavirus serotypes 16 and 18. In January 2002 a 47-year-old heterosexual male presented with Buschke-Lowenstein tumour and reported having had the disease for 12 years. The patient underwent thorough screening for sexually-transmitted diseases (which proved negative), abdominal CT, transanal US-endoscopy, inguinal ultrasound, chest X-ray and anorectal manometry, which revealed only localized disease. He was treated conservatively with radical local excision of the lesions. No postoperative complications were observed. Twelve months after surgery, there has been no local or remote recurrence and faecal continence is normal. The treatment of choice for Buschke-Lowenstein tumour is controversial; there is no evidence to support the need for demolitive surgery or chemo- and/or radiotherapy. The majority of authors prefer abdominoperineal amputation, but in our opinion conservative surgery is the best choice, especially in terms of the patient's quality of life.

RESUMO

The aim of the study was to evaluate laparoscopic-assisted colorectal resection for malignancies in terms of effectiveness, safety and medium-term survival, comparing our results with those reported in literature. From November 2000 to March 2004, 78 patients with colorectal malignancies underwent laparoscopic-assisted resection. All anastomoses were performed extracorporeally. Where indicated, patients underwent pre- or post-operative chemo-radiotherapy. All patients were followed up at regular intervals for a mean period of 18 months (2-42). The conversion rate was 14.1% and mean intraoperative blood loss was 120 cc. The post-operative morbidity rate was 15.3%. The mean number of lymph nodes removed was 12 (3-38) and all resection margins were clear and adequate. The observed overall and "disease-free" survival rates were similar to those reported in literature. Although the body of evidence needs to be increased, our findings and the data in the literature suggest that laparoscopic-assisted resection for colorectal malignancies is safe and effective, also in the medium and long term.

RESUMO

The use of circular staplers for the treatment of haemorrhoids is a new technique that makes for better correction of the physiopathology of the condition, affords greater patient comfort and reduces health-care expenditure. This technique, which was invented by A. Longo in 1993, pulls up the haemorrhoidal cushions into their anatomical position, reduces or avoids postoperative pain, sparing the sensitive fibres of the anal canal, avoids anal canal stenosis and is not complicated by faecal incontinence. The authors present their experience in 41 patients affected by symptomatic haemorrhoidal prolapse and treated with a mucosal rectal prolapsectomy using a circular stapler. Each patient was followed up for 6 months to assess the incidence of complications and the degree of patient satisfaction. The results were compared with those reported in the literature, obtained using the Milligan-Morgan procedure. The Longo technique, which can be performed in the one-day surgery setting, allows very good relief of postoperative pain, rapid functional recovery and an early return to work, with a saving in health-care expenditure as compared with conventional treatment.
