Which is the correlation between carcinoid tumor and Laparoscopic Sleeve Gastrectomy? A case series and literature review.

Introduction: Gastric Carcinoid Tumors (GCT) are very rare in general population, but some studies evidenced a higher incidence among bariatric surgery patients. Laparoscopic Sleeve Gastrectomy (LSG) is a widely accepted procedure for the surgical treatment of morbid obesity. LSG acts both in reducing food intake and interfering with hormonal balance in the gut-brain axis.

High Resected Gastric Volume and poorly controlled DM2 in laparoscopic sleeve gastrectomy.

Background: Our aim is to evaluate the effects of High Resected Gastric Volume(HRGV) on poorly Type 2 Diabetes Mellitus(DM2) after Laparoscopic Sleeve Gastrectomy(LSG).

Methods: 256 patients were divided into two groups according to the RGV: < 1500 mL(Group A: 131 pts) and > 1500 mL(Group B: 147 pts). % excess body mass index loss (%EBMIL), Fasting Blood Glucose (FBG), HbA1c, C peptide were assessed before surgery and at the 3rd day, 6th,12th,24th,36th month after LSG.

Resolution of type 2 diabetes after sleeve gastrectomy: a 2-step hypothesis.

Background: Weight loss (WL) and altered gut hormonal levels are involved in glucose homeostasis after laparoscopic sleeve gastrectomy (LSG).

Objectives: The aim of this study was to evaluate the time-related effects of WL, ghrelin, and glucacon-like peptide-1 (GLP-1) plasma concentrations on type 2 diabetes resolution after LSG.

Setting: University hospital, Italy.

Effect of Resected Gastric Volume on Ghrelin and GLP-1 Plasma Levels: a Prospective Study.

Background: The correlation between resected gastric volume (RGV) and neuro-humoral changes (ghrelin and GLP-1) after laparoscopic sleeve gastrectomy (LSG) and their effects on type 2 diabetes mellitus (T2DM) has been evaluated.

Materials: Ninety-eight patients were divided in two groups: RGV <1200 mL (group A: 53 pts) and RGV >1200 mL (group B: 45 pts). Insulin secretion (insulin area under the curve (AUC)), insulinogenic index (IGI) and insulin-resistance (homeostasis model assessment, HOMA) were assessed before and after surgery (at the 3rd day and 6, 12 and 24 months after LSG) using the oral glucose tolerance test (OGTT).

The effect of sleeve gastrectomy on GLP-1 secretion and gastric emptying: a prospective study.

Background: Rapid gastric emptying has been proposed to justify the increase in glucagon-like polypeptide-1 (GLP-1) after laparoscopic sleeve gastrectomy (LSG).

Objectives: To assess gastric emptying changes after LSG and their relationship with GLP-1 secretion.

Setting: San Salvatore Hospital general surgery unit, University of L'Aquila, Italy.

Twelve years of gastric GIST A retrospective study of laparoscopic and open approach.

Purpose: The authors wanted to evaluate the outcome of laparoscopic and open resection for gastric GISTs, in the long and short run with a retrospective study based on 63 consecutive patients.

Methods: Two surgical groups were compared according to age, sex, ASA group and Surgical procedure: a laparoscopic resection was performed on 30 patients (47,7%) while the open approach was preferred for 33 patients (52,3%). Duration of surgery, blood loss, positive resection margins, postoperative morbidity, postoperative ileus, hospital stay, tumor's mean dimensions, degree of malignancy and recurrences rate and 5-years mortality were compared in subgroups.

Unexpected anal squamous cells carcinoma after open hemorrhoidectomy.

We report a case of unexpected anal squamous cells carcinoma found in hemorrhoidectomy specimen. The patient had a 3-year history of prolapsing hemorrhoids. A prolapsing hemorrhoid was present at eleven o'clock in lithotomy.

Ultrasonic versus standard electric dissection in laparoscopic cholecystectomy in patients with acute calculous cholecystitis, complicated by peritonitis: influence on the postoperative systemic inflammation and immune response. A prospective randomized study.

Background: Ultrasonic surgery can dissect structures and divide vessels by the effect produced by vibrations in the tissues. It is believed to be less traumatic than the more commonly used monopolar electrosurgery (ELC). Laparoscopic techniques are being used increasingly in surgical conditions complicated by peritonitis.

Concomitant gastrointestinal stromal tumor of the stomach and gastric adenocarcinoma in a patient with billroth 2 resection.

Background. With this study we focus on the etiopathogenesis and on the therapy of the simultaneous occurrence of Gastric gastrointestinal stromal tumor (gGIST) and adenocarcinoma of the stomach in a patient with Billroth II gastric resection (BIIGR). We report the first case of this event and a review of the literature.

New harmonic scalpel versus conventional hemostasis in right colon surgery: a prospective randomized controlled clinical trial.

Background: The Harmonic Scalpel (HS) is a device that uses vibrations to coagulate and cut tissues simultaneously. Its advantages are represented by minimal lateral thermal tissue damage, less smoke formation, no neuromuscular stimulation and no transmission of electricity to the patient.

Methods: A total of 211 consecutive patients (113 men, 98 women; mean age 64 years) undergoing hemicolectomy for cancer of the right colon were divided into two groups, namely those in whom the operation was performed using a new HS handpiece (NHS; 108 patients) and those assigned to conventional hemostasis (CH; 103 patients).
