Perioperative immunonutrition proved to be safe and useful in increasing the perioperative immunologic cell response. It may contribute toward improving the preparation and relaxation of the intestinal loops despite the shorter intestinal preparation.

Third degree haemorrhoidal prolapse remains the best indication for stapled haemorrhoidopexy. This procedure may also be indicated in fourth degree haemorrhoidal prolapse. Patients with fourth degree haemorrhoids may be subjected to this procedure following adequate discussion of the outcome.

Radical resection resulted in a favourable clinical course. Typing of HPV sequences in the management of patients affected by extensive anal condylomatosis may be useful.

There is currently still no consensus regarding the best technique for implanting prolonged-venousaccess devices (PVAD). One hundred ninety-six patients underwent surgical PVAD positioning using an all-surgical cutdown approach to the cephalic vein (CV). When surgical cannulation proved impossible, the patient was converted to percutaneous positioning. A retrospective analysis was performed on the difference between these two techniques. Among the 196 patients who underwent the surgical insertion of a PVAD, 23 (11.7%) were converted to percutaneous cannulation. For the surgical cannulation group, the median operating time was 35 minutes vs the 52.5 minutes needed for the percutaneous cannulation group. The median time of fluoroscopy amounted to eight seconds for the surgical cannulation group vs 18 seconds for the percutaneous cannulation group. Complications were observed in 23/196 patients (11.7%): 9/23 patients (39.1%) developed infections. Deep venous thrombosis was observed in 4/23 patients (17.4%). Pneumothorax and arterial hematoma developed in 5/23 patients (21.7%), all cases of percutaneous placement. PVAD malfunction was observed in 3/23 patients (13.0%). We concluded that surgical cutdown is faster than the percutaneous approach and safer for both patient and surgeon, involving a shorter time of exposure to radiation and reducing the risk of infection.

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.

Prolonged venous access devices (PVADs) have become indispensable in antiblastic protocols for the treatment of cancer patients, in anti-infection protocols for acquired immunodeficiency syndrome (AIDS) patients and in the management of chronic malabsorption syndromes. Using these catheters carries the risk of several complications, and some are potentially lethal, for example, cardiac embolization of catheter fragments. Rupture is a complication almost exclusive to catheters positioned percutaneously: after using this technique, device malfunction can occur due to catheter kinking after its excessively medial introduction in the subclavian vein. The early recognition of any pinch-off sign (POS) is fundamental in preventing catheter rupture that frequently follows this complication. Other factors can be involved in early rupture, for example, excessive force on a syringe used to clear a catheter that shows early signs of malfunction, or a strength defect in the materials used in the catheter construction. This report describes an early rupture case of an initially correctly positioned catheter and reviews 20 such cases in the recent literature.
