Comparison of results after one year between sleeve gastrectomy and gastric bypass in patients with BMI ≥ 50 kg/m².

Background: Although laparoscopic sleeve gastrectomy (LSG) was initially described as the first step of a 2-stage procedure for high-risk patients requiring laparoscopic Roux-en-Y gastric bypass (LRYGB), it is now being used as a single-stage procedure. Experience with laparoscopic bariatric surgery is growing, such that LRYGB is increasingly feasible for patients with body mass index (BMI) ≥ 50 kg/m². Nevertheless, outcomes for such category of patients following LSG and LRYGB are lacking.

Five-year weight loss in primary gastric bypass and revisional gastric bypass for failed adjustable gastric banding: results of a case-matched study.

Background: Despite their now frequent use, the long-term results for adjustable gastric bands are variable and often less than gastric bypass. Laparoscopic Roux-en-Y gastric bypass (LRYGB) provides good early results and seems to be the revisional procedure of choice. Nevertheless, the long-term outcomes following revisional LRYGB (rLRYGB) for failed adjustable gastric banding have not been compared with those for primary LRYGB (pLRYGB).

Five-year outcomes of gastric bypass for super-super-obesity (BMI≥60 kg/m²): a case matched study.

Background: Laparoscopic gastric bypass (LRYGB) is feasible for patients with body mass index (BMI)≥60 kg/m² (super-super-obesity [SSO]) but long-term data are lacking. The objective of this study was to compare the 5-year weight loss and changes in obesity-related co-morbidities after LRYGB for SSO and non-SSO patients.

Methods: From January 2004 to November 2008, 32 SSO and 320 non-SSO patients underwent LRYGB.

Similar postoperative safety between primary and revisional gastric bypass for failed gastric banding.

Importance: Adjustable gastric bands are widely used because of low postoperative morbidity, but their long-term results are poor, often leading to revisional surgery.

Objective: To assess the safety of revisional procedures by comparing the 30-day outcomes of primary gastric bypass vs revisions following failed adjustable gastric banding.

Design, Setting, And Participants: Retrospective review using logistic regression models to compute odds ratios (95% CIs) across preoperative body mass index (calculated as weight in kilograms divided by height in meters squared) quartiles to evaluate the risk for major adverse outcomes at 30 days (death, venous thromboembolism, reinterventions, and failure to be discharged).

Is laparoscopy a safe approach for diffuse appendicular peritonitis? Feasibility and determination of risk factors for post-operative intra-abdominal abscess.

Background: Several studies have assessed feasibility and early outcomes of the laparoscopic approach for complicated appendicitis (CA). However, these studies suffer from limitations due to the heterogeneous definitions used for CA. No studies have assessed feasibility and early post-operative outcomes of the laparoscopic approach in the specific management of diffuse appendicular peritonitis (DAP).

Lateral incisional hernia repair by the retromuscular approach with polyester standard mesh: topographic considerations and long-term follow-up of 61 consecutive patients.

Background: Because of the lack of published data and the relative rarity of lateral incisional hernia (LIH), their repair remains a major challenge for surgeons. The aim of the present study was to evaluate the outcome of LIH treated by the retromuscular approach (RMA) with a polyester standard mesh.

Methods: Sixty-one patients were treated between June 2000 and November 2007 in an academic tertiary referral center using one standardized surgical technique and one type of mesh.

Retromuscular mesh repair of midline incisional hernia with polyester standard mesh: monocentric experience of 261 consecutive patients with a 5-year follow-up.

Background: Midline incisional hernia (MIH) repair remains a major challenge for surgeons. Multiple procedures and types of mesh to treat incisional hernia are available. We evaluated outcomes of MIH treated by retromuscular mesh repair (RMR) using a polyester standard prosthesis.

Etonorgestrel concentrations in morbidly obese women following Roux-en-Y gastric bypass surgery: three case reports.

Background: Pregnancy should be avoided for 12 to 18 months after Roux-en-Y gastric bypass (RYGB) surgery. The etonorgestrel (ENG)-releasing implant (Implanon®) may represent a safe and effective contraceptive method in morbidly obese women who are candidates for bariatric surgery. In addition, the subcutaneous delivery of steroid is unaffected by malabsorptive surgery.

Prognostic significance of 18q LOH in sporadic colorectal carcinoma.

Identification of molecular alterations with implication for prognosis and sensibility to chemotherapeutic agents represents a great challenge in colorectal carcinoma treatment. Controversial results have been reported on prognostic value of chromosome 18q loss. Ninety-seven unselected patients with sporadic colorectal carcinoma Stage II and III were investigated for loss of heterozygosity at 18q D18S58 and D18S61 loci.

[Bariatric surgery: surgical techniques and their complications].

Bariatric surgery is the only treatment permitting significant and long lasting results for patients suffering from morbid obesity. Indications are BMI>40 kg/m(2) or BMI >35 kg/m(2) associated with one or multiples comorbidities. In all cases, a multidisciplinary approach is required.

Value of a systematic operative protocol for cocaine body packers.

Background: Internal concealment of illicit drugs during international drug traffic represents an important problem in developed countries. These drug traffickers are called "body packers." The aim of this study was to analyze retroprospectively the surgical indications and complications for cocaine body packers and to describe our systematic operative protocol.

Prognostic evaluation of the new American Joint Committee on Cancer/International Union Against Cancer staging system for hepatocellular carcinoma: analysis of 112 cirrhotic patients resected for hepatocellular carcinoma.

Background: In 2002, the American Joint Committee on Cancer and the International Union Against Cancer redefined the T-classification for hepatocellular carcinoma, shifting the cutoff value for tumor size from 2 to 5 cm and giving more emphasis to vascular invasion.

Methods: A retrospective cohort study was conducted on 223 consecutive patients with hepatocellular carcinoma observed between 1990 and 2002. One hundred twelve were resected and considered for retrospective analysis.

[Prognostic factors and long term outcome after surgery for hilar cholangiocarcinoma. Univariate and multivariate analysis].

Aim of the study was to evaluate the surgical strategy for the treatment of the hilar cholangiocarcinoma, focusing on the clinicopathological factors influencing the outcome. Between January 2001 and December 2003 23 patients out of 33 underwent surgery for hilar cholangiocarcinoma. All patients underwent resection of the extrahepatic biliary duct.

Minimally invasive surgical treatment of esophageal achalasia.

Background And Objectives: A minimally invasive approach is considered the treatment of choice for esophageal achalasia. We report the evolution of our experience from thoracoscopic Heller myotomy (THM) to laparoscopic Heller myotomy (LHM). Our objective is to define the efficacy and safety of these 2 approaches.

Hemoperitoneum from a spontaneous rupture of a giant hemangioma of the liver: report of a case.

Hemangioma is the most common benign tumor of the liver and it is often asymptomatic. Spontaneous or traumatic rupture, intratumoral bleeding, consumption coagulopathy, and rapid growth are mandatory surgical indications. We report a case of giant hemangioma of hepatic segments II and III, which presented as hemoperitoneum, and were treated successfully with preoperative transcatheter arterial embolization (TAE) and hepatic bisegmentectomy.

Surgical treatment of hepatocellular carcinoma in elderly cirrhotic patients: personal experience.

Background: Due to the longer life expectancy of the world's population, the number of elderly cirrhotic patients undergoing surgery for hepatocellular carcinoma (HCC) is increasing. Our study evaluates the benefits of hepatic resections for HCC in cirrhotic patients aged over 65, analysing the early and long-term surgical results.

Patients And Methods: We retrospectively considered a series of 46 patients receiving hepatic resection for HCC.
