BACKGROUND: A significant gap presently exists between box-lap and virtual-reality simulators and live surgery. Live animal and cadaver use has significant downsides. We have developed a high fidelity, real tissue simulator that allows training in laparoscopic foregut operations. METHODS: Our foregut surgery model is based on porcine tissue blocks that include lungs, heart, aorta, esophagus, diaphragm, stomach, duodenum, liver, and spleen. The tissue block is mounted in a human mannequin and perfused with artificial blood...

BACKGROUND: About 20% of the population has cholelithiasis and this is the main abdominal cause of hospitalization in developed countries. Considering that only in the United States about 700,000 cholecystectomies are done each year, it is possible to estimate the importance of the problem for public health. OBJECTIVE: To describe a two-incision laparoscopic cholecystectomy (TILC) technique using only conventional material, without increasing complications or operative time...

BACKGROUND: Renal transplantation is the most successful therapy for improving survival and quality of life for end-stage renal disease (ESRD). Living donor kidney transplantation (LDKTx) has been used as an alternative to reduce the stay on the waiting list of patients with ESRD. Laparoscopic donor nephrectomy (LDN) has become the standard procedure for LDKTx. OBJECTIVE: This study aims to describe evolution of surgical technique with LDN at our institute. MATERIALS AND METHODS: We retrospectively analyzed our experience with LDN performed from January, 2003 to November, 2016, focusing on describing modifications of the surgical technique and devices made during those years...

BACKGROUND: Hybrid liver resection is considered a modality of minimally invasive surgery; however, there are doubts regarding loss of benefits of laparoscopy due to the use of an auxiliary incision. We compared perioperative results of patients undergoing hybrid × open and hybrid × pure laparoscopic resections. METHODS: Consecutive patients undergoing liver resection between June 2008 and January 2016 were studied. Study groups were compared after propensity score matching (PSM)...

BACKGROUND: Genitourinary tuberculosis still continues to plague developing countries and is a significant cause of morbidity as well as mortality in the developing world. At present, nearly 55% of the patients of genitourinary tuberculosis (GUTB) need surgical management. Owing to the presence of dense adhesions and loss of normal anatomical planes, GUTB was considered to be a contraindication to laparoscopic surgery. However, recent literature shows laparoscopy to be feasible in GUTB...

INTRODUCTION: Implanting a magnetic lower esophageal sphincter augmentation device (LINX, Torax Medical) has become an increasingly common option in the surgical management of gastroesophageal reflux disease. As the enthusiasm for placing this device increases, experience in the management of device-related complications-including erosion-is necessary. METHODS: We report a staged approach to LINX removal in a 64-year-old female with symptoms of odynophagia secondary to partial erosion of a LINX device into the esophagus...

BACKGROUND: The safety and oncologic completeness of video-assisted lateral neck dissection (VALND) for papillary thyroid carcinoma (PTC) with lateral neck lymph node metastasis (LNM) have been reported. However, their generalization has remained limited because the advantages and drawbacks are not well demonstrated. MATERIALS AND METHODS: A total of 64 patients with PTC and unilateral lateral neck LNM who underwent total thyroidectomy with central compartment neck dissection and lateral neck dissection (LND) were prospectively enrolled...

BACKGROUND: Although liver cirrhosis with portal hypertension (PH) contributes significantly to morbidity and mortality in abdominal surgery, many authors still consider this disease as an indication for surgery. In many reports, however, numerous treatment modalities focus on hypersplenism secondary to PH, irrespective of splenomegaly and PH. The proven benefits of laparoscopy seem especially applicable to patients with this complex disease. This study evaluates the safety and efficacy of laparoscopic perisplenic artery ligation (SAL) in patients with hepatobiliary disease and PH...

BACKGROUND: Endoscopic intrapyloric Botox (onabotulinumtoxin A; Allergan Pharmaceuticals) injections can improve postfundoplication gastroparesis, but responses are not durable. Surgical pyloroplasty may relieve gastroparetic symptoms, but patient selection criteria are poorly defined. We hypothesize that pyloroplasty provides durable improvement in patients whose symptoms improved after Botox injection. STUDY DESIGN: A retrospective chart review was performed of patients with postfundoplication gastroparesis who improved after Botox injection and then underwent pyloroplasty...

BACKGROUND: Pancreatic pseudocyst (PP) is the commonest cystic lesion of the pancreas. Internal drainage of PPs can be accomplished by traditional open or recently by minimally invasive laparoscopic or endoscopic approaches. We aimed to evaluate and compare the clinical outcomes after endoscopic, laparoscopic, and open drainage. METHODS: Seventy-one patients with PP underwent endoscopic (n = 35), laparoscopic (n = 4), and open surgical drainage (n = 32)...

PURPOSE: Our previous work demonstrated that intentional peritoneal injury reduces the incidence of recurrence of a patent processus vaginalis even after removal of the suture. Therefore, the necessity of permanent suture has been brought into question because of the risk of suture granuloma formation. The purpose of this study was to evaluate the efficacy of absorbable, braided versus permanent, braided suture in a rabbit survival model of laparoscopic percutaneous ligation of the processus vaginalis with intentional peritoneal injury...

BACKGROUND: Patients with gastroesophageal reflux disease (GERD) also frequently suffer from concomitant hiatal hernia. It has been described that a preoperative hiatal hernia of ≥3 cm is associated with a more than threefold relative risk for reflux symptom recurrence after fundoplication without mesh reinforcement. In this report, we describe our experience with the implantation of dual-sided composite PTFE/ePTFE meshes in a tension-free fashion during laparoscopic antireflux surgery (LARS)...

BACKGROUND: Spigelian hernia represents a rare entity. Traditionally, it was repaired by the open technique. Various laparoscopic techniques have emerged periodically. Most laparoscopic repairs use the technique of placing an intraperitoneal onlay mesh (IPOM). There is currently a tendency to close the hernia defect. METHODS: A 68-year-old man was admitted to our hospital complaining of vague abdominal pain and discomfort. Physical examination revealed a bulky palpable mass on the left side of the patient...

BACKGROUND: In the past decade, the minimally invasive repair of pectus excavatum (MIRPE) has become the treatment of choice for severe pectus excavatum (PE), proving acceptable to excellent cosmetic results. Recently, autologous fat grafting (FG) has been identified in aesthetic and reconstructive surgery to ideally handle volume and contour defects. We report our experience about FG in the treatment of residual minor defects after MIRPE and a proposal for a new indication of this largely adopted technique...
