Pour une chirurgie définitive d'emblée dans les ulcères gastro-duodénaux compliqués [Definitive surgery in complicated gastroduodenal ulcers].

Indications for surgical therapy in uncomplicated peptic ulcer disease have decreased considerably since the introduction of H2-receptor blocking drugs and more recently omeprazole. On the other side, the number of acute complications such as perforation or hemorrhage has remained nearly constant. The recent literature seems to indicate that the pattern of patients presenting with complications has changed and that the number of acute ulcers has increased. In a review of 283 patients, we found 150 perforated ulcers (PU) and 133 bleeding ulcers (BU). Almost all the patients with PU and 70% of the patients with BU have been treated operatively. The mortality is 14.3% and 12.5%, respectively. The vast majority of our patients have chronic ulcers, and only 7% have acute or subacute lesions confirmed by histologic examination. Based on our experience and the literature, we propose a therapeutic algorythm for these two conditions.

Enhanced recovery after surgery: are we ready, and can we afford not to implement these pathways for patients undergoing radical cystectomy?

Enhanced recovery after surgery (ERAS) for radical cystectomy seems logical, but our study has shown a paucity in the level of clinical evidence. As part of the ERAS Society, we welcome global collaboration to collect evidence that will improve patient outcomes.

Chirurgie du diabète: provocation ou réalité [Surgery for diabetes: challenge or reality?]

Bariatric surgery techniques can usually increase either sensitivity or insulin resistance, acting on three different levels: decrease of food intake, malabsorption and modifications of entero-insulaire axis activity. This latter is taken into account in order to develop a new protocol to obtain diabetes remission without important weight loss and nutritional deficiencies. Preliminary results are interesting but they come from very short time studies with few patients. Moreover, complications rate is at present very high. Knowing better gastrointestinal mechanisms of diabetes control and especially incretins role is absolutely necessary before identifying surgery as a true metabolic treatment.

The 5th anniversary of "Patient Safety in Surgery" - from the Journal's origin to its future vision.

A prospective study was undertaken to determine prognostic markers for patients with obstructive jaundice. Along with routine liver function tests, antipyrine clearance was determined in 20 patients. Four patients died after basal investigations. Five patients underwent definitive surgery. The remaining 11 patients were subjected to percutaneous transhepatic biliary decompression. Four patients died during the drainage period, while surgery was carried out for seven patients within 1-3 weeks of drainage. Of 20 patients, only six patients survived. Basal liver function tests were comparable in survivors and nonsurvivors. Discriminant analysis of the basal data revealed that plasma bilirubin, proteins and antipyrine half-life taken together had a strong association with mortality. A mathematical equation was derived using these variables and a score was computed for each patient. It was observed that a score value greater than or equal to 0.84 indicated survival. Omission of antipyrine half-life from the data, however, resulted in prediction of false security in 55% of patients. This study highlights the importance of addition of antipyrine elimination test to the routine liver function tests for precise identification of high risk patients.

Free conjunctival autologous graft for bleb repair and bleb reduction after trabeculectomy and nonpenetrating filtering surgery.

PURPOSE: To describe methods and outcomes of excisional revision of a filtering bleb (bleb revision) using free conjunctival autologous graft either for bleb repair or for bleb reduction after trabeculectomy and deep sclerectomy with an implant. METHODS: Retrospective medical records were reviewed for a consecutive non-comparative case series comprising patients who underwent excisional revision of a filtering bleb between May 1998-January 2001. Excisional revision using free conjunctival autologous graft (bleb revision) was performed either for bleb repair, to treat early and late leaks and hypotony with maculopathy, or for bleb reduction, to improve ocular pain, discomfort, burning, foreign body sensation, tearing, and fluctuations of visual acuity. The revision consisted of bleb excision and free conjunctival autologous graft. The bleb histopathology was analyzed in patients who underwent bleb repair. RESULTS: Sixteen patients were included in the study, consisting of nine patients who had a trabeculectomy and seven patients who had a deep sclerectomy with an implant. Bleb revision was necessary in 14 patients due to leaking filtering bleb (bleb repair), and in 2 patients due to bleb dysesthesia (bleb reduction). After a follow-up of 15.1 +/- 8.4 months, the mean intraocular pressure (IOP) rose from 7.8 +/- 6.3 mm Hg to 14.3 +/- 6.5 mm Hg, and the visual acuity from 0.4 +/- 0.3 to 0.7 +/- 0.3, with a P value of 0.008 and 0.03, respectively. The complete success rate at 32 months, according to the Kaplan-Meier survival curve, was 38.3%, and the qualified success rate was 83.3%. Four patients (25%) required additional suturing for persistent bleb leak. To control IOP, antiglaucoma medical therapy was needed for six patients (37.5%) and repeated glaucoma surgery was needed for one patient. CONCLUSION: Free conjunctival autologous graft is a safe and successful procedure for bleb repair and bleb reduction. However, patients should be aware of the postoperative possibility of requiring medical or surgical intervention for IOP control after revision.

Quoi de neuf en chirurgie [Novelties in surgery in 2013?].

Multidisciplinary management of colorectal liver metastases allows an increase of about 20% in the resection rate of liver metastases. It includes chemotherapy, interventional radiology and surgery. In 2013, the preliminary results of the in-situ split of the liver associated with portal vein ligation (ALLPS) are promising with unprecedented mean hypertrophy up to 70% at day 9. However, the related morbidity of this procedure is about 40% and hence should be performed in the setting of study protocol only. For pancreatic cancer, the future belongs to the use of adjuvant and neo adjuvant therapies in order to increase the resection rate. Laparoscopic and robot-assisted surgery is still in evolution with significant benefits in the reduction of cost, hospital stay, and postoperative morbidity. Finally, enhanced recovery pathways (ERAS) have been validated for colorectal surgery and are currently assessed in other fields of surgery like HPB and upper GI surgery.

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of current practice in a general surgery department

Objective: There is little evidence regarding the benefit of stress ulcer prophylaxis (SUP) outside critical care setting. Over-prescription of SUP is not devoid of risks. This prospective study aimed to evaluate the use of proton pump inhibitors (PPIs) for SUP in a general surgery department.Methods: Data collection was performed prospectively during an 8-week period on patients hospitalized in a general surgery department (58 beds) by pharmacists. Patients with a PPI prescription for the treatment of ulcers, gastro-oesophageal reflux disease, oesophagitis or epigastric pain were excluded. Patients admitted twice during the study period were not re-included. The American Society of Health-System Pharmacists guidelines on SUP were used to assess the appropriateness of de novo PPI prescriptions.Results: Among 255 consecutive patients in the study, 138 (54%) received a prophylaxis with PPI, of which 86 (62%) were de novo PPI prescriptions. One-hundred twenty-nine patients (94%) received esomeprazole (according to the hospital drug policy). The most frequent dosage was 40 mg/day. Use of PPI for SUP was evaluated in 67 patients. Fifty-three patients (79%) had no risk factors for SUP. Twelve and 2 patients had one or two risk factors, respectively. At discharge, PPI prophylaxis was continued in 34% of patients with a de novo PPI prescription.Conclusion: This study highlights the overuse of PPIs in non-ICU patients and the inappropriate continuation of PPI prescriptions at discharge.Treatment

Chirurgie viscérate chez le patient greffé ou en attente d'une transplantation [Visceral surgery in organ transplant recipients or in patients awaiting transplantation]

Patients receiving immunosuppression are at higher risk for gastrointestinal complications: mortality is high if they are not diagnosed and treated rapidly. Systematic screening for cholelithiasis or diverticular disease, and prophylactic surgery, are not recommended systematically anymore. Patients awaiting a transplant with abdominal symptoms should be investigated without delay and surgery, if indicated and whenever possible based on the anaesthetic evaluation, should be performed. In the transplant population, a high degree of suspicion must be raised in case of any abdominal symptom. Radiological investigations and surgery without delay are often the only ways to preserve the function of the graft and optimize the patient's survival.

Resuming motor vehicle driving following orthopaedic surgery or limb trauma.

Following elective orthopaedic surgery or the treatment of a fracture, patients are temporarily unable to drive. This loss of independence may have serious social and economic consequences for the patient. It is therefore essential to know when it is safe to permit such patients to return to driving. This article, based upon a review of the current literature, proposes recommendations of the time period after which patients may safely return to driving. Practical decisions are made based upon the type of surgical intervention or fracture. Swiss legislation is equally approached so as to better define the decision.

Ultrastructural changes of the internal limiting membrane removed during indocyanine green assisted peeling versus conventional surgery for idiopathic macular epiretinal membrane

Résumé : Introduction : L'objectif de cette étude était d'une part d'évaluer les caractéristiques histologiques des fragments cellulaires rétiniens attachés à la limitante interne après vitrectomie et pelage d'une membrane epirétinienne, et d'autre part de mettre en évidence des différences histologiques entre les cas opérés avec ou sans l'aide d'ICG dilué dans du glucose 5%. Méthodes Nous avons examiné rétrospectivement l'histologie de 88 spécimens de membranes épimaculaires contenant la limitante interne de la rétine, qui ont été enlevés chirurgicalement entre 1995 et 2003. L'analyse histologique a centré principalement l'attention sur la présence et les caractéristiques des fragments cellulaires rétiniens attachés à la limitante interne. L'analyse statistique a comparé les résultats entre le groupe I (chirurgie conventionnelle sans l'aide de l'ICG) et le groupe II (chirurgie à l'aide de l'ICG). Résultats Soixante et onze patients ont eu une vitrectomie sans l'aide de l'ICG (groupe I) et 17 avec l'aide de l'ICG (groupe II). Le nombre de débris de cellules de Müller à la surface rétinienne de la limitante interne était plus important dans le groupe I (sans ICG) que dans le groupe II (avec ICG) (40.8% versus 11.8% ; p = 0.024). Des larges fragments cellulaires rétiniens attachés à la limitante interne ont été plus fréquemment observés dans le groupe I (sans ICG) que dans le groupe II (avec ICG) (63.4% versus 23.5%; p= 0.003). Dans cinq (7%) cas du groupe I, de gros éléments cellulaires rétiniens ont été mis en évidence (des axones neuraux ou des vaisseaux sanguins). De tels éléments n'ont pas été retrouvés dans les spécimens du groupe II (avec ICG). Conclusions L'utilisation de l'ICG dilué dans du glucose 5% pour faciliter le pelage d'une membrane épimaculaire et notamment l'ablation de la limitante interne de la rétine semble diminuer de manière significative le nombre et la taille des débris des cellules de Muller adhérents à la face rétinienne de la membrane limitante interne de la rétine. Cette observation suggère que l'utilisation per-opératoire d'ICG dilué dans du glucose 5% facilite l'ablation de la limitante interne pendant la chirurgie de la membrane epirétinienne en diminuant l'adhérence de la limitante interne à la rétine.

Pulse pressure variation-guided fluid therapy after cardiac surgery: A pilot before-and-after trial.

PURPOSE: The aim of this study is to study the feasibility, safety, and physiological effects of pulse pressure variation (PPV)-guided fluid therapy in patients after cardiac surgery. MATERIALS AND METHODS: We conducted a pilot prospective before-and-after study during mandatory ventilation after cardiac surgery in a tertiary intensive care unit. We introduced a protocol to deliver a fluid bolus for a PPV ≥13% for at least >10 minutes during the intervention period. RESULTS: We studied 45 control patients and 53 intervention patients. During the intervention period, clinicians administered a fluid bolus on 79% of the defined PPV trigger episodes. Median total fluid intake was similar between 2 groups during mandatory ventilation (1297 mL [interquartile range 549-1968] vs 1481 mL [807-2563]; P = .17) and the first 24 hours (3046 mL [interquartile range 2317-3982] vs 3017 mL [2192-4028]; P = .73). After adjusting for several baseline factors, PPV-guided fluid management significantly increased fluid intake during mandatory ventilation (P = .004) but not during the first 24 hours (P = .47). Pulse pressure variation-guided fluid therapy, however, did not significantly affect hemodynamic, renal, and metabolic variables. No serious adverse events were noted. CONCLUSIONS: Pulse pressure variation-guided fluid management was feasible and safe during mandatory ventilation after cardiac surgery. However, its advantages may be clinically small.

Guidelines for perioperative care for pancreaticoduodenectomy: Enhanced Recovery After Surgery (ERAS®) Society recommendations.

BACKGROUND & AIMS: Protocols for enhanced recovery provide comprehensive and evidence-based guidelines for best perioperative care. Protocol implementation may reduce complication rates and enhance functional recovery and, as a result of this, also reduce length-of-stay in hospital. There is no comprehensive framework available for pancreaticoduodenectomy. METHODS: An international working group constructed within the Enhanced Recovery After Surgery (ERAS®) Society constructed a comprehensive and evidence-based framework for best perioperative care for pancreaticoduodenectomy patients. Data were retrieved from standard databases and personal archives. Evidence and recommendations were classified according to the GRADE system and reached through consensus in the group. The quality of evidence was rated "high", "moderate", "low" or "very low". Recommendations were graded as "strong" or "weak". RESULTS: Comprehensive guidelines are presented. Available evidence is summarised and recommendations given for 27 care items. The quality of evidence varies substantially and further research is needed for many issues to improve the strength of evidence and grade of recommendations. CONCLUSIONS: The present evidence-based guidelines provide the necessary platform upon which to base a unified protocol for perioperative care for pancreaticoduodenectomy. A unified protocol allows for comparison between centres and across national borders. It facilitates multi-institutional prospective cohort registries and adequately powered randomised trials.
