RESUMO

BACKGROUND: Outpatient appendectomy for acute appendicitis is a feasible, yet not widely performed procedure, as there are no universally accepted criteria for patient selection. The aim of this study was to assess preoperative clinical factors associated with successful short-stay appendectomy (SSA) and establish a predictive score to help with patient selection. METHODS: All consecutive laparoscopic appendectomies performed in our institution between January 2013 and June 2015 were retrospectively analyzed. Several preoperative clinical and biological variables were compared between patients with SSA, defined as a postoperative stay <24 h, and those needing inpatient care. Logistic regression analysis was used to identify variables independently associated with SSA, and these variables were then used to create a predictive score. RESULTS: A total of 578 patients were included, 303 (53%) in the SSA group and 275 (48%) in the long-stay appendectomy (LSA) group. In multivariate analysis, male gender (OR 1.61, 95% CI 1.12-2.31, p = 0.010), ASA class I-II (OR 9.52, 95% CI 1.65-180.69, p = 0.037), absence of generalized guarding (OR 3.55, 95% CI 1.30-11.41, p = 0.019), C-reactive protein <100 mg/dl (OR 3.09, 95% CI 1.81-5.42, p < 0.001) and leukocyte count <20 g/l (OR 2.06, 95% CI 1.02-4.30, p = 0.046) were independently associated with SSA. These five parameters were used to construct a predictive score, whereby ≥17 (range 0-21) was defined as the optimal threshold to predict SSA with a high sensitivity (95.6%) and negative predictive value (82.2%). CONCLUSIONS: A purely clinical predictive score based on five widely used preoperative parameters can be used to identify eligible patients for short-stay appendectomy.

RESUMO

PURPOSE: Postoperative ileus (POI) is a frequent complication after abdominal surgery; nonetheless, it remains poorly defined. Our aim was to achieve an international consensus among leading colorectal surgeons on definition, prevention, and treatment of POI. METHODS: Thirty-five experts from five continents participated in a three-round Delphi process. Round 1 contained open-ended questions on POI and postoperative nausea and vomiting (PONV). Round 2 included closed-ended questions. Round 3 measured agreement on a 5-point Likert scale. Consensus was defined when items were rated as agree or strongly agree by at least 70 % of the experts. RESULTS: Experts reached following consensus: POI is a temporary inhibition (86 %) of gastrointestinal motility after surgical intervention due to non-mechanical causes (89 %) and prevents sufficient oral intake (96 %). Abdominal distension/tenderness are the most relevant clinical signs (71 %). Nasogastric tube placement is not mandatory (78 %) but can be removed without previous clamping (81 %)/gastrointestinal contrast study (100 %). Preventive measures are recommended to decrease the risk of POI (96 %): narcotic sparing analgesia (89 %) and fluid optimization (74 %). Treatment of POI should include stimulation of ambulation (96 %) and stop of opioids (74 %). Total parenteral nutrition is recommended from the 7th day without sufficient oral intake (81 %). There was no consensus on the ranking of POI's symptoms, on the imaging modality of choice for the diagnosis of POI, neither on the difference between POI and PONV. CONCLUSIONS: This Delphi study achieved consensus on the definition, relevant clinical signs, prevention, treatment, and supportive care of POI. Areas of non-consensus were identified (necessity and modality of radiologic imaging to establish the diagnosis, difference between POI and PONV), giving opportunity for further research.

RESUMO

BACKGROUND: Seroma formation and lymphoedema are frequently encountered complications after radical lymph node dissection (RLND). Attempts to reduce the lymphatic morbidity include the use of Ultrasonic Scalpel. The aim of the present analysis was to assess the impact of the ultrasonic scalpel on the amount of drained lymph after lymph node dissection. METHODS: Patients listed for a RLND or completion lymph node dissection (CLND) were enrolled in a prospective randomized trial to compare the impact of two surgical dissection techniques (USS versus control) on the amount of drained lymph. The lymph drained in 24 h was collected. Our primary endpoint was to compare the daily amount of drained lymph between the two groups. Secondary endpoints were the comparison of drained lymph with the BMI of the patients, the gender and the surgical site (axilla, groin). RESULTS: Eighty patients were randomly assigned to the USS group or the Control (C) group. No difference was measured in the total amount of lymph drained (USS: 2908 ± 2453 ml vs. C: 3898 ± 5791 ml; p-value = 0.382). The result was also similar after adjusting for gender, age, and BMI. A significant higher amount of lymph was measured after inguinal dissection with USS compared to axillary (p < 0.001). CONCLUSION: The study suggests that the use of Harmonic scalpel did not influence the amount of lymph drained after RLND and not support the theory that USS induces oversealing of lymphatics. TRIAL REGISTRATION: Clinical Trial NCT02476357 . Registered 20 of February 2015.

RESUMO

Ulcerative colitis (UC) has a prevalence of 1 in 1000 inhabitants in Switzerland. The diagnosis of UC is based on a typical clinical presentation that involves bloody diarrhea, characteristic endoscopic features with continuous inflammation involving the rectum, and compatible histology. UC develops in genetically susceptible individuals with a dysregulated mucosal immune system. This article highlights latest insights into the pathogenesis, diagnosis, and therapy of UC.


La rectocolite ulcéro-hémorragique (RCUH) représente une maladie fréquente en Suisse avec une prévalence de 1 sur 1000 habitants. Le diagnostic se base sur la présentation clinique typique avec des diarrhées sanglantes, une image endoscopique caractéristique avec une inflammation continue qui touche pratiquement toujours le rectum, et une image histologique compatible. La RCUH se développe chez des individus avec prédisposition génétique et une dérégulation du système immunitaire colique. Cet article fait le point sur la pathogenèse, le diagnostic et les approches thérapeutiques de cette maladie.

RESUMO

BACKGROUND: Many attempts to prevent lymphatic complications following therapeutic lymph node dissection (TLND) have included modifications in surgical techniques through the use of ultrasonic scalpels (USS) or lymphostatic agents. Previous randomized studies that enrolled heterogeneous groups of patients attempted to confirm the efficacy of such techniques. The aim of the present study was to evaluate the efficacy of the USS following TLND. METHODS: Between 2009 and 2013, patients undergoing inguinal or axillary TLND or completion lymph node dissection after positive sentinel lymph node biopsy for melanoma, squamous cell carcinoma or sarcoma were randomized into two surgical dissection technique groups. In the USS dissection arm, surgery was conducted using a USS. These were compared with a control group whereby ligation and monopolar electrocautery was utilized. For axillary dissection, a standardized level III lymphadenectomy was performed. A complete inguinal lymphadenectomy including Cloquet's node was performed, and at the end of the procedure a Redon suction drain was routinely placed in the axilla and groin. The primary endpoint was to compare the time to drain removal in both groups, while the secondary endpoint was to evaluate the rate of complications (infection, fistula, lymphocele formation, wound dehiscence, lymphedema) between the two groups. RESULTS: A total of 80 patients were enrolled in this trial; 40 patients were randomly assigned to both the USS group and the control (C) group. No significant differences were observed in terms of duration of drainage (USS: 31 ± 20 vs. C: 32 ± 18; p = 0.83); however, a significantly increased rate of lymphedema (defined as an increased circumference of the operated limb of more than 10 %) was identified in the USS group (USS: 50 % vs. C: 27.5 %; p = 0.04). No other significant differences were recorded for postoperative complications, including surgical site infection (USS: 5 % vs. C: 7.5 %; p = 0.68), lymphatic fistula (USS: 5 % vs. C: 2.5 %; p = 0.62), lymphocele (USS: 32.5 % vs. C: 22.5 %; p = 0.33), and hematoma (USS: 5 % vs. C: 2.5 %; p = 0.62). CONCLUSION: The use of USS failed to offer any significant reduction in length of drain usage and operative complication, but it seems to increase the rate of lymphedema formation.

RESUMO

Treatment of patients with locally advanced rectal cancer remains challenging. Preoperative imaging with pelvic MRI allows to identify patients for multimodal treatment including induction chemothe- rapy or neoadjuvant radio-chemotherapy and an extended surgical resection. With multidisciplinary approach and an experienced team, excellent oncologic results may be achieved, as well as a good function and quality of life, even with preservation of the anus in the majority of patients.

RESUMO

Mesenteric ischemia results from acute or chronic blood flow reduction in the mesenteric arterial or venous vascular supply. This is usually due to an embolus, thrombosis or intestinal hypoperfusion. Radiologic and / or endoscopic imaging and histology allow for diagnosis in high-risk patients with suggestive clinical symptoms and signs. Treatment aims at preventing multi-organ failure through medical treatment, saving intestinal integrity and resecting necrotic bowel segments. Rapid and multidisciplinary management is key in order to optimize treatment and avoid long-term debilitating consequences.


L'ischémie mésentérique est provoquée par l'interruption aiguë ou chronique du flux sanguin splanchno-mésentérique par des mécanismes comme l'embolie, la thrombose ou l'hypoperfusion intestinale. Le diagnostic est posé par imagerie et / ou endoscopie face à un tableau clinique évocateur dans un contexte à risque. La prise en charge vise la prévention d'une défaillance multiviscérale par un traitement médical, la préservation de l'intestin par une revascularisation et la résection des segments nécrotiques. Une prise en charge rapide et multidisciplinaire est cardinale afin d'optimiser le traitement et éviter des séquelles fonctionnelles graves à long terme.

RESUMO

BACKGROUND: Surgical site infection after stoma reversal is common. The optimal skin closure technique after stoma reversal has been widely debated in the literature. OBJECTIVE: We hypothesized that pursestring near-complete closure of the stoma site would lead to fewer surgical site infections compared with conventional primary closure. DESIGN: This study was a parallel prospective multicenter randomized controlled trial. SETTINGS: This study was conducted at 2 university medical centers. PATIENTS: Patients (N = 122) presenting for elective colostomy or ileostomy reversal were selected. INTERVENTIONS: Pursestring versus conventional primary closure of stoma sites were compared. MAIN OUTCOME MEASURES: Stoma site surgical site infection within 30 days of surgery, overall surgical site infection, delayed healing (open wound for >30 days), time to wound epithelialization, and patient satisfaction were the primary outcomes measured. RESULTS: The pursestring group had a significantly lower stoma site infection rate (2% vs 15%, p = 0.01). There was no difference in delayed healing or patient satisfaction between groups. Time to epithelialization was measured in only 51 patients but was significantly longer in the pursestring group (34.6 ± 20 days vs 24.1 ± 17 days, p = 0.02). LIMITATIONS: This study was limited by the variability in procedures and surgeons, the limited follow-up after 30 days, and the inability to perform blinding. CONCLUSION: Pursestring closure after stoma reversal has a lower risk of stoma site surgical site infection than conventional primary closure, although wounds may take longer to heal with the use of this approach. REGISTRATION NUMBER: NCT01713452 (www.clinicaltrials.gov).

RESUMO

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.

RESUMO

C. difficile is transmitted in a faecal-oral mode and is widespread in hospital environment. Symptoms of Clostridial infection range from asymptomatic carriage to life-threatening toxic colitis. The treatment of a Clostridial infection is dependent on the seriousness of the symptoms. The diagnosis of the pathogen as well as the introduction of an efficient antibiotic therapy is crucial. Oral metronidazole is the gold standard in treatment of mild infection. Vancomycin should be introduced only in refractory cases or in particular situations. While there is a desire to avoid colectomy, inappropriate delay in a very ill patient can be fatal. Judgement on when to intervene is difficult and requires analysis of the factors which predict outcome with and without surgery. A total abdominal colectomy sparing the rectum with end ileostomy is the procedure of choice.

RESUMO

Skin necrosis of the foot, oedema and lymphangitis from stonefish (Synanceia verrucosa) sting are complications well known for a long time and with potential long-term sequelae. Literature reports of stonefish envenomation give no specific reference on soft tissue management and surgical reconstruction. This is the first report describing a case of foot stonefish envenomation treated by vacuum-assisted closure therapy as an easy to use, accessible and simple adjuvant tool for management of large soft tissue necrosis.

RESUMO

OBJECTIVE: To prospectively assess the construct and criterion validity of ClassIntra version 1.0, a newly developed classification for assessing intraoperative adverse events. DESIGN: International, multicentre cohort study. SETTING: 18 secondary and tertiary centres from 12 countries in Europe, Oceania, and North America. PARTICIPANTS: The cohort study included a representative sample of 2520 patients in hospital having any type of surgery, followed up until discharge. A follow-up to assess mortality at 30 days was performed in 2372 patients (94%). A survey was sent to a representative sample of 163 surgeons and anaesthetists from participating centres. MAIN OUTCOME MEASURES: Intraoperative complications were assessed according to ClassIntra. Postoperative complications were assessed daily until discharge from hospital with the Clavien-Dindo classification. The primary endpoint was construct validity by investigating the risk adjusted association between the most severe intraoperative and postoperative complications, measured in a multivariable hierarchical proportional odds model. For criterion validity, inter-rater reliability was evaluated in a survey of 10 fictitious case scenarios describing intraoperative complications. RESULTS: Of 2520 patients enrolled, 610 (24%) experienced at least one intraoperative adverse event and 838 (33%) at least one postoperative complication. Multivariable analysis showed a gradual increase in risk for a more severe postoperative complication with increasing grade of ClassIntra: ClassIntra grade I versus grade 0, odds ratio 0.99 (95% confidence interval 0.69 to 1.42); grade II versus grade 0, 1.39 (0.97 to 2.00); grade III versus grade 0, 2.62 (1.31 to 5.26); and grade IV versus grade 0, 3.81 (1.19 to 12.2). ClassIntra showed high criterion validity with an intraclass correlation coefficient of 0.76 (95% confidence interval 0.59 to 0.91) in the survey (response rate 83%). CONCLUSIONS: ClassIntra is the first prospectively validated classification for assessing intraoperative adverse events in a standardised way, linking them to postoperative complications with the well established Clavien-Dindo classification. ClassIntra can be incorporated into routine practice in perioperative surgical safety checklists, or used as a monitoring and outcome reporting tool for different surgical disciplines. Future studies should investigate whether the tool is useful to stratify patients to the appropriate postoperative care, to enhance the quality of surgical interventions, and to improve long term outcomes of surgical patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT03009929.

RESUMO

RATIONALE: Gouty panniculitis, characterised by the deposition of monosodium urate crystals in subcutaneous tissue, is a rare clinical manifestation of gout. PATIENT CONCERNS: The case of a 67-year-old man is reported, who presented an erythematous nodule on the upper part of the right buttock suspicious for an abscess. This was in the context of chemotherapy for non-Hodgkin's lymphoma. DIAGNOSES: Histopathologic examination demonstrated gouty panniculitis. INTERVENTIONS: Because infection was suspected, an incision was performed. The lesion was found to be densely calcified and friable, without purulent discharge. Therefore, a surgical en-bloc resection was performed. OUTCOMES: The wound healed slowly initially due to a combination of malnutrition, chemotherapy and infection. A wound infection with Enterococcus faecium was treated with antibiotic therapy (carbapenem for seven days) and local therapy. At 6-week follow up the wound showed good granulation tissue and was healing well by secondary intention. The patient was instructed to continue anti-hyperuricaemic treatment. LESSONS SUBSECTIONS: In patients known to have long-standing hyperuricaemia and gout with nonspecific subcutaneous erythematous nodules, gouty panniculitis should be considered.
