Cannabinoid Hyperemesis Syndrome: A Case Report of Cyclic Severe Hyperemesis and Abdominal Pain with Long-Term Cannabis Use

Introduction. Cannabinoid Hyperemesis Syndrome (CHS) is a rare condition that includes cyclic severe vomiting in subjects who have been consuming large doses of cannabis for several years. One of the major diagnostic criteria is the alleviation of symptoms by hot showers. The syndrome was first described in 2004 and is so far neither completely und...

The inflammatory properties of propofol are still debated. Apolipoprotein A-I is involved in the inflammation. We sought to determine how propofol or its solvent Intralipid® modulate Apolipoprotein A-I and the inflammatory response after surgical stress. Patients undergoing laparoscopic inguinal hernia repair were allocated to anesthesia with propo...

Background: Recent developments in minimal invasive surgery have led to laparoendoscopic single site surgery (LESS). This new approach has great potential but remains technically challenging. In order to relieve these difficulties many authors have adapted robotic technology to single site surgery. Numerous approaches have been developed and there...

Elective laparoscopic sigmoid resection for diverticulitis has proven short-term benefits, but little data are available from prospective randomized trials regarding long-term outcome, quality of life, and functional results. Of 113 patients randomized to undergo laparoscopic (LAP) versus open (OP) sigmoid resection for diverticulitis, 105 (93%, LA...

Single-incision laparoscopy (SIL) is a rapidly growing procedure in the field of surgery. The most frequent site of abdominal access is the umbilicus. Its appearance can be altered during SIL procedures. The literature suggests that the umbilicus plays an important role in the overall physical appearance of patients. This study therefore investigat...

Single-incision laparoscopic and natural orifice translumenal endoscopic surgery (NOTES) are technically challenging methods. Robotics might have the potential to overcome such hurdles with computer technology. The da Vinci Standard and S System (Intuitive, Sunnyvale, USA) were used in human cadavers and pigs to perform single-incision transabdomin...

The aim of this study was to compare open and laparoscopic sigmoid resection for diverticulitis with the patient and the nursing staff blinded to the surgical approach. A total of 113 patients scheduled for an elective sigmoidectomy were randomized to receive either a conventional open (54 patients) or a laparoscopic (59 patients) approach. Postope...

Set-up and docking of the da Vinci surgical system are assumed to extend overall operating times. We hypothesized that these tasks could be achieved in adequate times. Therefore, a prospective analysis of set-up and docking times of the da Vinci Surgical System was conducted. We prospectively analysed set-up and docking times with the da Vinci surg...

Laparoscopic splenectomy (LS) is becoming the "gold standard" technique for splenectomy. The aim of this study was to evaluate the hospital experience, body image, and cosmesis after LS or open splenectomy (OS). Patients who underwent LS or OS were invited to fill out questionnaires evaluating their hospital experience, body image, and cosmetic res...

Due to improved ergonomics and dexterity, robotic surgery is promoted as being easily performed by surgeons with no special skills necessary. We tested this hypothesis by measuring IQ elements, computer gaming skills, general dexterity with chopsticks, and evaluating laparoscopic experience in correlation to performance ability with the da Vinci ro...

Amyand's hernia is an atypical groin hernia which contains the vermiform appendix. The aim of this study was to review a single institution's experience in the clinical presentation, management and prognostic factors of this rare hernia. The authors reviewed records of all patients undergoing hernia surgery from 1996 to 2006 at their institution, a...

The aim of this study was to assess the risk factors associated with mortality and morbidity following emergency or urgent colorectal surgery. All data regarding the 462 patients who underwent emergency colonic resection in our institution between November 2002 and December 2007 were prospectively entered into a computerized database. The median ag...

Natural orifice transluminal endoscopic surgery (NOTES) is a multidisciplinary surgical technique. If conventional endoscopic instrumentation can be easily mastered, surgeons with laparoscopic experience could head NOTES interventions. Thirty individuals were tested for endoscopic dexterity. Group 1 included seven gastroenterologists, group 2 inclu...

The lack of haptic feedback (HF) in robotic surgery is one of the major concerns of novice surgeons to that field. The superior visual appearances acquired during robotic surgery may give clues that make HF less important. We surveyed 52 individuals on their perception of HF during robotic surgery. The first group of 34 surgically inexperienced peo...

Pleural or peritoneal effusions (ascites) are frequent in terminal stage malignancies. Medical management may be hazardous. A 60-year-old man with metastatic malignant melanoma presented refractory ascites as well as bilateral pleural effusions. After failure of the medical treatment, bilateral pleural aspiration and paracentesis became necessary t...

Pyoderma gangrenosum is an aseptic skin disease. The ulcerative form of pyoderma gangrenosum is characterized by a rapidly progressing painful irregular and undermined bordered necrotic ulcer. The aetiology of pyoderma gangrenosum remains unclear. In about 70% of cases, it is associated with a systemic disorder, most often inflammatory bowel diseas...

Surgical repair of parastomal hernias is usually performed through a laparotomy (stoma translocation) or a peristomal incision (mesh repair). Laparoscopic approach may minimize the risks of mesh infection and, thus, represents an attractive alternative. Permacol (Tissue Science Laboratories plc, Aldershot, Hampshire, U.K.) is a new biomaterial impl...

Since 1990, laparoscopy and minimally invasive techniques in general, have been widely adopted in the field of digestive surgery. However, due to its technical limitations, the use of conventional laparoscopy remains limited to procedures of low (cholecystectomy, appendectomy) or intermediate (Nissen fundoplication, sigmoidectomy) complexity. This...

Optimal treatment of groin hernia is a primary public health concern. The inguinal hernia is associated with dysfunctions of the collagen matrix of genetic or acquired origin. Recurrence rate after hernia surgery without mesh reinforcement is estimated at 10-15%. The use of mesh decreases the risk of recurrence by between 50 and 70%. The open techn...

Since an increasing number of appendectomies are performed via laparoscopy, it is crucial to determine the impact of this approach on appendix carcinoid (AC) outcome. The goal of this study was to compare results of laparoscopic (LAP) versus open (OP) appendectomy for AC according to intend to treat approach. A retrospective review (1991-2003) iden...

The diagnosis of acute appendicitis remains difficult in certain circumstances, as in case of the Amyand's hernia. Development of an acute appendicitis in an external hernia is called Amyand's hernia in honour of the English surgeon, Claudius Amyand, author of the first appendicectomy of the history of medicine in 1735. Amyand's hernia is a rare oc...

The introduction of complex and long-term intravenous therapies requires reliable venous access. Totally implantable central venous access devices improve treatment and quality of life for patients. However, the long-term function of such devices depends on an analysis adapted to each patient. Many complications could be avoided by a methodological...

The patient, a 67-year-old man, presented with nonspecific abdominal pain over the last 3 weeks. The personal history was uneventful with the exception of a known diverticulosis. Abdominal examination was normal. Barium enema revealed a large caecal tumor, that was suspected to be malignant (Fig. 2.1). Coloscopy showed the presence of an unique, bu...

The first reported series of laparoscopic colorectal resection in the early nineties were met with skepticism, probably because of the complexity of the technique. Since then, the laparoscopic procedure has gained acceptance in terms of faisability and safety. Since early 1995, colorectal surgery for benign diseases is included among the laparoscop...
