Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB) are anatomically different bariatric operations. RYGB achieves greater weight loss compared with LAGB. Changes in the gut microbiome have been documented after RYGB, but not LAGB, and the microbial contribution to sustainable surgical weight loss warrants further evaluation. We hypothesized that RYGB imposes greater changes on the microbiota and its metabolism than LAGB, and that the altered microbiota may contribute to greater weight loss...

BACKGROUND: New surgical techniques for nephrectomy mainly related to early diagnosis made possible by advances in imaging studies have been developed in recent decades. However, postoperative renal dysfunction is a constant concern because of the major problems faced by healthcare services and by the patients themselves. To assess risk factors for developing acute renal failure (ARF) in patients submitted to nephrectomy in a university hospital. METHODS: Seventy-seven patients submitted to nephrectomy for benign and malignant diseases in a university hospital were evaluated in respect to preoperative and postoperative creatinine clearance...

Biliary duct anomalies are commonly encountered during laparoscopic cholecystectomy. Advancements in the field of surgery allow for enhanced intraoperative detection of these abnormalities. Fluorophore injection and near-infrared (NIR) imaging can provide real-time intraoperative anatomic feedback without intraoperative delays and ionizing radiation. This report details two cases where the PINPOINT Endoscopic Fluorescence Imaging System (NOVADAQ, Ontario, Canada) was used to identify anomalies of the biliary tree and guide operative decision-making...

Gastric volvulus (GV) is characterized by the abnormal rotation of a portion of the stomach around a horizontal or vertical axis that can cause obstruction, vascular disorder and even strangulation, and may evolve into necrosis or even perforation. It can be classified according to its aetiology into primary or secondary GV, according to its anatomy into axial organ or into axial mesenteric GV, and according to its presentation into chronic or acute GV. Both types of volvulus require treatment; however, in spite of the classic treatment being open surgery, there is no standard treatment, nor is there consensus on the alternative of choice at present...

Laparoscopy has become the standard surgery mode of right hemicolectomy, including conventional laparoscopy, hand-assisted laparoscopic surgery (HALS), single-port laparoscopic surgery (SPLS), natural orifices translumenal endoscopic surgery (NOTES) and robotic laparoscopy. How to select reasonable laparoscopic mode could be confusing sometimes. For patients, safety, cost-effectiveness and radical cure of the surgery are very important. For doctors, advance and convenience of the surgery must be considered as well...

REVIEW
Ashley Russo, Vivian E Strong
The World Health Organization (WHO) has declared gastric carcinoma a global health concern and gastric cancer remains the third leading cause of cancer deaths worldwide. With the rising incidence of gastric cancer, a body of both retrospective and randomized data has emerged since the early 1990's evaluating the role of minimally invasive platforms in the management of gastric cancer. While Eastern studies have shown that the laparoscopic approach is safe and feasible for advanced gastric cancer in Eastern patients, it is not clear whether this is true for patients in the West...

PURPOSE: Although the standard treatment for patients with locally advanced rectal cancer managed by preoperative chemoradiotherapy (CRT) is a radical resection, local excisions are used in highly-selective cases. Recently, transanal minimally-invasive surgery (TAMIS) has emerged as a feasible technique for local excision of midrectal lesions. We assess the feasibility of using TAMIS to treat patients with locally advanced rectal cancer who showed good response to CRT. METHODS: From October 2010 to June 2013, 35 consecutive patients with rectal cancer managed by using preoperative CRT underwent TAMIS...

BACKGROUND: Esophageal carcinomas are highly malignant tumors with a high frequency of lymph node and distant organ metastasis. Treatment for recurrent tumors is generally decided on an individual basis. Although multidisciplinary treatments involving chemotherapy, surgical resection, and radiation are performed, the prognosis remains poor. Here, we report a case of prolonged recurrence-free survival (38 months) after esophageal carcinoma surgery and subsequent laparoscopic adrenalectomy for right adrenal metastasis...

The idea to use natural orifices as an access route for operations in the body has inspired many clinicians and researchers worldwide. Some of these expected a continuation of the development from open surgery to laparoscopic surgery finally to a less invasive modality. Others hoped for economic benefits for endoscopists to take over previous surgical patients into gastroenterological departments. The first experimental studies demonstrated that the initial expectations could not be implemented in a short period of time...

Crohn's disease (CD) is a chronic inflammatory disease of digestive tract. Approximately 70% of patients with CD require surgical intervention within 10 years of their initial diagnosis, despite advanced medical treatment alternatives including biologics, immune suppressive drugs and steroids. Refractory to medical treatment in CD patients is the common indication for surgery. Unfortunately, surgery cannot cure the disease. Minimally invasive treatment modalities can be suitable for CD patients due to the benign nature of the disease especially at the time of index surgery...

Perioperative otorrhagia in association with non-otolaryngologic surgery is rare. The cause is typically attributed to the physiologic derangements associated with the Trendelenburg position and pneumoperitoneum during laparoscopic surgery. The most well-accepted etiology is an increase in arterial and venous pressures causing the rupture of subcutaneous capillaries, although the exact etiology remains unclear. We present the first reported case of bilateral spontaneous otorrhagia associated with robotically assisted laparoscopic surgery involving a reduced Trendelenburg position and low-pressure pneumoperitoneum...
