Trends of bariatric surgery in France during the last 10 years: analysis of 267,466 procedures from 2005–2014

BACKGROUND During the past decade, the field of bariatric surgery has changed dramatically. OBJECTIVES The study aims to summarize and perform a periodic assessment of the current trends in the use of bariatric surgery in France and review findings on the long-term progression of bariatric surgery. The data were extracted from the national registry Programme de Médicalisation des Systèmes d׳Information from 2005 to 2014. SETTING National health system and private practice in France. METHODS We identified all hospitalizations during which a bariatric procedure was performed for the treatment of morbid obesity from 2005 to 2014 in France. Data were reviewed for patient characteristics and the number and types of bariatric procedures. We also analyzed the setting and the characteristics of the centers and the difference of the activity between the public and private sector. RESULTS Between 2005 and 2014, the number of bariatric operations increased fourfold. Sleeve gastrectomy became the most performed bariatric intervention, representing 60.7% of bariatric activity in 2014. There was a concomitant steep increase in sleeve gastrectomy, with Roux-en-Y gastric bypass increasing slightly overall and a substantial decrease in adjustable gastric banding. In 2014, 481 centers performed bariatric surgery. Among them, one third performed<30 operations/yr. We observed an overall in-hospital mortality ranging from .038% to .05% during the last 3 years. CONCLUSION Bariatric surgery is increasing in France, with a fourfold augmentation of interventions in the last 10 years. The number of sleeve gastrectomies has increased considerably. This activity is performed in numerous centers, one third of them performing<30 interventions/yr.

Jejuno–ileal diverticulitis: Etiopathogenicity, diagnosis and management

Highlights • Diagnosis is often difficult and delayed because clinical symptoms are not specific.• The etiopathogenesis of jejuno–ileal diverticulosis is unclear.• Flatulent dyspepsia = epigastric pain abdominal discomfort, flatulence one or two hours after meals.• The extraluminal air develops an arrowhead-like shape surrounded by inflammatory tissue when the diverticulum is perforated.• In the presence of complications, surgical resection with reestablishment of the bowel continuity is the preferred treatment option.

Laparoscopic Entry Techniques in Obese Patient: Veress Needle, Direct Trocar Insertion or Open Entry Technique?

Laparoscopy is a common procedure in bariatric surgery. Serious complications can occur during laparoscopic entry as reported by Ahmad et al. (Cochrane Database Syst Rev 15:2, 2012). Several techniques, instruments, and approaches to minimize the risk of injury (the bowel, bladder, major abdominal vessels, and an anterior abdominal wall vessel) have been introduced. These methods include the standard technique of insufflation after insertion of the Veress needle, the open (Hasson technique), the direct trocar insertion, and optical trocar insertion. Furthermore, it is more difficult to perform in the obese patient, especially if the first trocar is not umbilical. This is because obese patients have a very thick abdominal wall (particularly in women) as well as a thick peritoneum. The aim of this article was to demonstrate the safety of various laparoscopic entry techniques in obese patient.

Hiatal Hernia of the Roux-en-Y Gastric Bypass Pouch 8 years After Surgery

Laparoscopic Roux-en-Y gastric bypass procedure (LRYGBP) is common in bariatric surgery. Although several complications of LRYGBP have been identified, mainly because of the complex anatomy involved in this procedure, hiatal hernia of the gastric pouch is yet to be detailed. Here, we report the case of a patient with herniation of the gastric pouch through the hiatal orifice, complicating the LRYGBP 8 years after surgery. We describe the laparoscopic repair and discuss the mechanisms leading to this rare complication.

Squamous cell carcinoma of middle rectum: Literature review

INTRODUCTION Squamous cell carcinoma SCC of the rectum is a distinct entity. We report a very rare case of squamous cell carcinoma of the middle rectum. PRESENTATION OF CASE The patient was a 62-year-old woman who presented with a history of rectal bleeding and discomfort. Colonoscopy revealed a polypoid tumour of the middle rectum. Biopsies of this mass revealed a poorly differentiated SCC of the rectum. CT scan of the chest, abdomen and pelvis was negative for distal metastases. The patient received combined chemo-radiation followed by surgical excision. The postoperative period was uncomplicated. DISCUSSION The pathogenesis of rectal SCC remains unclear and diagnosis is often delayed. Diagnostic criteria have been proposed. MRI of the rectum and trans-rectal endoscopic ultrasound R-EUS provide essential information to plan a therapeutic approach. The squamous cell carcinoma antigen level is not suitable for initial diagnosis of rectal SCC. Most authors conclude that the surgery is the gold standard treatment. Tumour stage is the most important prognostic predictor of SCC. CONCLUSION Squamous cell carcinoma of the rectum is a distinct entity. Before the final choice of treatment is made, digestive surgeons should bear in mind this rare tumour.

Complications of bariatric surgery: Presentation and emergency management

The epidemic in obesity has led to an increase in number of so called bariatric procedures. Doctors are less comfortable managing an obese patient after bariatric surgery. Peri-operative mortality is less than 1%. The specific feature in the obese patient is that the classical signs of peritoneal irritation are never present as there is no abdominal wall and therefore no guarding or rigidity. Simple post-operative tachycardia in obese patients should be taken seriously as it is a WARNING SIGNAL. The most common complication after surgery is peritonitis due to anastomotic fistula formation. This occurs typically as an early complication within the first 10 days post-operatively and has an incidence of 1-6% after gastric bypass and 3-7% after sleeve gastrectomy. Post-operative malnutrition is extremely rare after restrictive surgery (ring, sleeve gastrectomy) although may occur after malabsorbative surgery (bypass, biliary pancreatic shunt) and is due to the restriction and change in absorption. Prophylactic cholecystectomy is not routinely carried out during the same procedure as the bypass. Superior mesenteric vein thrombosis after bariatric surgery is a diagnosis which should be considered in the presence of any postoperative abdominal pain. Initially a first etiological assessment is performed (measurement of antithrombin III and of protein C and protein S, testing for activated protein C resistance). If the least doubt is present, a medical or surgical consultation should be requested with a specialist practitioner in the management of obese patients as death rates increase with delayed diagnosis.

Laparoscopic hernia: umbilical-pubis length versus technical difficulty.

Laparoscopic hernia repair is more difficult than open hernia repair. The totally extraperitoneal procedure with 3 trocars on the midline is more comfortable for the surgeon. We studied the impact of the length between the umbilicus and the pubis on the totally extraperitoneal procedure (95 hernias operated on in 70 patients). This length did not influence the totally extraperitoneal procedure in this study. Background: The laparoscopic repair of hernias is considered to be difficult especially for the totally extra-peritoneal technique (TEP) due to a limited working space and different appreciation of the usual anatomical landmarks seen through an anterior approach. The aim of our study has been to answer a question: does the umbilical-pubic distance, which influences the size of the mesh, affect the TEP technique used in the treatment of inguinal hernias? Methods: From January 2001 to May 2011, the umbilical-pubic (UP) distance was measured with a sterile ruler graduated in centimeters in all patients who underwent a symptomatic inguinal hernia by the TEP technique in two hernia surgery centers. The sex, age, BMI, hernia type, UP distance, operation time, hospital stay and complications were prospectively examined based on the medical records. Results: Seventy patients underwent 95 inguinal hernia repairs by the TEP technique. The umbilical-pubic distance average was 14 cm (10 to 22) and a 25 kg/m2 (16–30) average concerning the body mass index (BMI). Seventy percent of patients were treated on an outpatient basis. The postoperative course was very simple. There was no recurrence of hernia within this early postoperative period. Conclusion: The umbilical-pubic distance had no influence on the production of TEP with 3 trocars on the midline in this study.

Metastatic meningiomas: an unusual clinical and pathological diagnosis with highly variable outcome

Metastatic meningioma is a rare situation. We conducted a retrospective study from our databases and identified cases of metastatic meningioma. We report three presentations of patients with medical history of surgical removal of meningioma presenting several years later a liver tumor with bone metastasis or multiple lung tumors. These observations highlight the difficulty of the clinical and pathological diagnosis and the absence of consideration of metastatic state for histologically “benign” but clinically aggressive meningiomas in the current WHO 2007 classification of meningiomas. We also reviewed published cases of metastatic meningiomas since they are clearly distinguished from haemangiopericytoma.

A rare variant of inguinal hernia: Cryptorchid testis at the age of 50 years. Etiopathogenicity, prognosis and management

INTRODUCTION Cryptorchidism is characterized by the extra-scrotal position of the testis. The surgical community has little to no knowledge of cryptorchid testis in adults apart from of pediatric surgeons. Therefore, we sought to describe this unusual cause of inguinal hernia. PRESENTATION OF CASE A 50-year-old man was referred with a inguinal hernia. Diagnosis of cryptorchidism was made during surgery, as the patient underwent an operation for repair of his left inguinal hernia. The testicle was non-viable and a left testicle was resected. Histopathology report confirmed a atrophic testis without testicular germ cell tumor (TGCT). DISCUSSION This is an extremely rare case of cryptorchidism revealed in an adult. The patient remained asymptomatic for 50 years. Most studies have concluded that there is a direct correlation between how long the testis was subjected to a cryptorchid position and TGCT incidence. The recommended age of surgical correction is before the age of 2 years. In our case, we did not find correlation between the time of surgery and risk of TGCT. Histopathology report confirmed the presence of leydig cells, seminiferous tubule and Sertoli cells without TGCT. Very little is known about link between cryptorchidism and TGCT. The correct diagnosis of inguinal hernia is usually made during an inguinal hernia repair. CONCLUSION The surgeon must always be alert to the possibility of cryptorchid testis during a surgical exploration of an inguinal hernia. In suspected cases, laparoscopy ultrasonographic, CT scan and laparoscopy evaluation may be helpful in diagnosing of this atypical inguinal hernia before surgery.
