Improvement of Lipid Profile after One-Anastomosis Gastric Bypass Compared to Sleeve Gastrectomy.

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.

Selection criteria for surgery in patients with obstructed defecation, rectocele and anorectal prolapse.

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.

5-fluorouracil and weekly oxaliplatin combined with radiotherapy for locally advanced rectal cancer: surgical complications and long-term results.

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)).

Colitis cystica profunda of the rectum: report of a case and review of the literature.

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.

Laparoscopic-assisted resection is safe and effective for colorectal malignancies: a single-centre experience.

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.

Insertion of prolonged venous access device: a comparison between surgical cutdown and percutaneous techniques.

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.

Giant condyloma acuminatum of the anorectum (Buschke-Lowenstein tumour): a case report of conservative surgery.

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.

Role of transperineal Doppler and ultrasound in evaluating anal sphincter injury after stapled haemorrhoidopexy.

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.

[Advantages of surgical treatment of hemorrhoids with mechanical sutures].

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.
