A Surgical Instrument Cover for the Prevention of Thermal Injuries During Laparoscopic Operations.

Introduction: Accidental thermal injuries are infrequent, nonetheless, dangerous complications in laparoscopic surgery. Burns are produced because of direct contact, lack of instrument insulation and capacitive coupling. Biological fluids on the surface of laparoscopic instruments behave as electric conductors on the sheath and may be responsible for accidental thermal injuries.

HypoparaNet: A Database of Chronic Hypoparathyroidism Based on Expert Medical-Surgical Centers in Italy.

Hypoparathyroidism is a rare disease characterized by low serum calcium levels and absent or deficient parathyroid hormone level. Regarding the epidemiology of chronic hypoparathyroidism, there are limited data in Italy and worldwide. Therefore, the purpose of this study was to build a unique database of patients with chronic hypoparathyroidism, derived from the databases of 16 referral centers for endocrinological diseases, affiliated with the Italian Society of Endocrinology, and four centers for endocrine surgery with expertise in hypoparathyroidism, to conduct an epidemiological analysis of chronic hypoparathyroidism in Italy.

Radiofrequency-Based Identification Medical Device: An Evaluable Solution for Surgical Sponge Retrieval?

Background: A retained surgical item in patients (gossypiboma) is a persisting problem, despite consistent improvements and existing guidelines in counting instruments and sponges. Previous experiences with radiofrequency identification technology (RFID) tracking sponges show that it could represent an innovation, in order to reduce the criticism and increase the effectiveness during surgical procedures. We present an automated system that allows reduction of errors and improves safety in the operating room.

Multi-port versus single-port cholecystectomy: results of a multi-centre, randomised controlled trial (MUSIC trial).

Background: Single-port laparoscopic surgery as an alternative to conventional laparoscopic cholecystectomy for benign disease has not yet been accepted as a standard procedure. The aim of the multi-port versus single-port cholecystectomy trial was to compare morbidity rates after single-access (SPC) and standard laparoscopy (MPC).

Methods: This non-inferiority phase 3 trial was conducted at 20 hospital surgical departments in six countries.

A magnetic levitation robotic camera for minimally invasive surgery: Useful for NOTES?

Background: Minimally invasive surgery (MIS) is rising in popularity generating a revolution in operative medicine during the past few decades. Although laparoscopic techniques have not significantly changed in the last 10 years, several advances have been made in visualization devices and instrumentation.

Methods: Our team, composed of surgeons and biomedical engineers, developed a magnetic levitation camera (MLC) with a magnetic internal mechanism dedicated to MIS.

Natural humoral immune response to ribosomal P0 protein in colorectal cancer patients.

Background: Tumor associated antigens are useful in colorectal cancer (CRC) management. The ribosomal P proteins (P0, P1, P2) play an important role in protein synthesis and tumor formation. The immunogenicity of the ribosomal P0 protein in head and neck, in breast and prostate cancer patients and the overexpression of the carboxyl-terminal P0 epitope (C-22 P0) in some tumors were reported.

Ligation of the intersphincteric fistula tract (LIFT): a minimally invasive procedure for complex anal fistula: two-year results of a prospective multicentric study.

Introduction: The surgical management of anal fistulas is still a matter of discussion and no clear recommendations exist. The present study analyses the results of the ligation of the intersphincteric fistula tract (LIFT) technique in treating complex anal fistulas, in particular healing, fecal continence, and recurrence.

Methods: Between October 2010 and February 2012, a total of 26 consecutive patients underwent LIFT.

Surgery for fistula-in-ano in a specialist colorectal unit: a critical appraisal.

Background: Several techniques have been described for the management of fistula-in-ano, but all carry their own risks of recurrence and incontinence. We conducted a prospective study to assess type of presentation, treatment strategy and outcome over a 5-year period.

Methods: Between 1st January 2005 and 31st March 2011,247 patients presenting with anal fistulas were treated at the University Hospital Tor Vergata and were included in the present prospective study.

Harmonic Focus™ versus "knot tying" during total thyroidectomy: a randomized trial.

The objective of the study is to compare the outcome of total thyroidectomy (TT) using the Harmonic Focus™ (HF) versus conventional "knot tying" (KT) in terms of operative time, parathyroid function and post-operative complications. This prospective study was designed with a random allocation of subjects using a drawing technique. Eighty-one consecutive patients were submitted to TT in 2010 and randomly divided into two groups: 43 patients operated using HF (HF group) and 38 patients operated using KT (KT group).

Laparoscopic treatment of a huge mesenteric chylous cyst.

Mesenteric chylous cysts are rare pathologic entities that often present with unspecific symptoms. The preoperative diagnosis requires all the common abdominal imaging techniques, but usually the correct diagnosis may be made only at the operation stage or during the histological examination. The treatment of choice is the complete surgical excision that may be safely performed by laparoscopy.

Reinterventions for specific technique-related complications of stapled haemorrhoidopexy (SH): a critical appraisal.

Introduction: Stapled haemorrhoidopexy (SH) is an attractive alternative to conventional haemorrhoidectomy (CH) because of reduced pain and earlier return to normal activities. However, complication rates are as high as 31%. Although some complications are similar to CH, most are specifically technique-related.

Squamous cell carcinoma of the breast. Report of two cases.

Squamous Cell Carcinoma (SCC) of the breast is a rare entity, not well known, nevertheless literature reports several signalings from different authors. Regarding ethiopathogenesis, SCC of the breast is still the object of numerous discordances and controversies. We report two cases of SCC of the breast referred to our institution in the last year.

Stapled hemorrhoidopexy: a prospective study from pathology to clinical outcome.

Stapled hemorrhoidopexy is widely accepted to treat hemorrhoids, but serious complications have been reported. In this prospective audit, we correlated clinical outcome with pathological findings. From January 2003 to April 2007, 94 patients underwent hemorrhoidopexy.

Skeletal muscle metastases from renal cell carcinoma: a case report.

In this paper, we describe a case of a 73-year old female with late skeletal muscle metastases from a clear-type renal cell carcinoma 8 years after total nephrectomy. The metastases were located in the right femoral quadriceps, in the sartorius muscle and adductor magnus muscle. A full clinical work-up was performed with blood examinations, radiological and pathological assessment.

Minilaparoscopic appendectomy for acute appendicitis.

Background: Minilaparoscopic appendectomy for appendicitis is not a well-established procedure. This approach provides less abdominal wall trauma, fewer complications, and excellent cosmetic results. Our aim was to show the feasibility and safety of the minilaparoscopic approach.

Robotic systems and surgical education.

This experimental study aimed at evaluating the efficiency of robots in the learning of surgical techniques. We recruited 40 surgeons, divided them into 2 groups of 20, each of which used the robotic system. The first group consisted of experienced physicians, and the second group comprised physicians in training.

Evidence-based appraisal of antireflux fundoplication.

Objective: To highlight the current available evidence in antireflux surgery through a systematic review of randomized controlled trials (RCTs).

Summary Background Data: Laparoscopic fundoplication is currently suggested as the gold standard for the surgical treatment of gastroesophageal reflux disease, but many controversies are still open concerning the influence of some technical details on its results.

Methods: Papers related to RCTs identified via a systematic literature search were evaluated according to standard criteria.

[Impact of laparoscopic surgery in the treatment of chronic abdominal pain syndrome].

Chronic abdominal pain syndrome is becoming increasingly important with regard to the quality of life of the patients and its social and economic impact, in terms of cost of hospitalization, income loss due to sick leave, and pharmaceutical costs for treatments which fail to offer either significant clinical improvement or resolution of the pain symptoms. The main symptom is chronic abdominal pain, which may vary in intensity and may be associated with constipation and episodes of vomiting, when the clinical picture evolves toward one of subocclusion or total occlusion of the bowel. We considered the following criteria in our selection of patients for this study: 1) quality of life, 2) constant use of antispastic and analgesic medications, 3) absence of any other diagnosticable pathology prior to the operation.
