The presence of a vermiform appendix in an inguinal hernia sac is known as Amyand's hernia. The aim of this systematic review was to gather information concerning its prevalence, clinical image, diagnosis, and treatment. The MEDLINE database was thoroughly searched using the keyword “Amyand's hernia.” Additional articles were gathered and evaluated. The true prevalence of Amyand's hernia seems lower than classically described. Its usual clinical image is identical to that of an incarcerated hernia, and thus it is almost impossible to diagnose preoperatively, although ultrasound and computed tomography can help. Treatment includes hernioplasty with or without appendectomy and/or mesh repair depending on the vermiform appendix's inflammation status, the patient's general condition, and other factors. Amyand's hernia generally has a good prognosis, although serious complications have been described. Surgeons should be prepared if they encounter Amyand's hernia because appropriate treatment ensures hernia repair without complications and with avoidance of recurrence.

Background The effect of music in the operating room is not fully understood. Through a systematic review the authors aim to give a conceptual presentation of the effect that music has on the pre- and postoperative course of surgical patients and on the effectiveness of the surgical work performed by both physicians and staff. Methods The search was conducted both on the basis of the Medical Subject Headings (MeSH) tree and as a text search using the Medline database (1946 to December 2011). The main search heading was “music in operating room” with the accessory keyword “surgery.” The selection criteria specified the English language and the availability of abstracts or full-text articles. From 85 articles listed with the corresponding search, 28 were relevant and enrolled for the review. Results Patients exhibit lower anxiety levels before and during surgery when hearing music and a significant reduction in analgesia and sedation requirements has been observed. Music was found to reduce the heart rate, blood pressure, and muscle effort of surgeons while at the same time increasing the accuracy of surgical tasks. Surgeons who played a musical instrument were found to perform surgical tasks faster. On the other hand, anesthesiologists report that music is associated with difficulties communicating and offering a stable level of sedation. The most appropriate music in the operating room seems to be the classical type. Conclusions Music in the operating room can have beneficial effects on patients by decreasing stress, anxiety, and the demand for analgesic and anesthetic drugs. For the surgical staff, music is considered to be distracting. For the surgeon, music can increase the speed and accuracy of task performance.

Foramen of Winslow hernia (FWH) is an extremely rare entity accounting for up to 8% of internal hernias and 0.08% of all hernias. Only 150 cases of FWH have been described in the literature to date with a peak incidence between the third and sixth decades of life. Three main mechanisms seem to be implicated in the FWH pathogenesis: (a) excessive viscera mobility, (b) abnormal enlargement of the foramen of Winslow, and (c) changes in the intra-abdominal pressure. The presence of an abnormally long bowel, enlargement of the right liver lobe or cholecystectomy, a “wandering cecum,” and defects of the gastrohepatic ligaments are some reported predisposing factors. Timely diagnosis through computed tomography facilitates the appropriate treatment before complications are evident. Although open repair has been mostly utilized, recently laparoscopic approach seems to gain ground due to the encouraging preliminary results. To date, the debate continues as to whether prophylactic measures to prevent recurrence of the FWH need to be undertaken: closure of the foramen, fixation of the highly mobilized viscera, or both.

We performed an evaluation of models, techniques, and applicability to the clinical setting of natural orifice surgery (mainly natural orifice transluminal endoscopic surgery [NOTES]) primarily in general surgery procedures. NOTES has attracted much attention recently for its potential to establish a completely alternative approach to the traditional surgical procedures performed entirely through a natural orifice. Beyond the potentially scar-free surgery and abolishment of dermal incision–related complications, the safety and efficacy of this new surgical technology must be evaluated. Studies were identified by searching MEDLINE, EMBASE, Cochrane Library, and Entrez PubMed from 2007 to February 2011. Most of the references were identified from 2009 to 2010. There were limitations as far as the population that was evaluated (only human beings, no cadavers or animals) was concerned, but there were no limitations concerning the level of evidence of the studies that were evaluated. The studies that were deemed applicable for our review were published mainly from 2007 to 2010 (see Methods section). All the evaluated studies were conducted only in human beings. We studied the most common referred in the literature orifices such as vaginal, oral, gastric, esophageal, anal, or urethral. The optimal access route and method could not be established because of the different nature of each procedure. We mainly studied procedures in the field of general surgery such as cholecystectomy, intestinal cancers, renal cancers, appendectomy, mediastinoscopy, and peritoneoscopy. All procedures were feasible and most of them had an uneventful postoperative course. A number of technical problems were encountered, especially as far as pure NOTES procedures are concerned, which makes the need of developing new endoscopic instruments, to facilitate each approach, undeniable. NOTES is still in the early stages of development and more robust technologies will be needed to achieve reliable closure and overcome technical challenges. Well-designed studies in human beings need to be conducted to determine the safety and efficacy of NOTES in a clinical setting. Among these NOTES approaches, the transvaginal route seems less complicated because it virtually eliminates concerns for leakage and fistulas. The transvaginal approach further favors upper-abdominal surgeries because it provides better maneuverability to upper-abdominal organs (eg, liver, gallbladder, spleen, abdominal esophagus, and stomach). The stomach is considered one of the most promising targets because this large organ, once adequately mobilized, can be transected easily with a stapler. The majority of the approaches seem to be feasible even with the equipment used nowadays, but to achieve better results and wider applications to human beings, the need to develop new endoscopic instruments to facilitate each approach is necessary.

Toll-like receptors (TLRs) are the key regulators of innate and adaptive immunity and are highly expressed during sepsis. Thus, studying the expression of TLRs in an animal septic model might indicate their possible association with acute kidney injury in sepsis. Seventy-two male C57BL/6J mice were used for this study. Randomly, these animals were divided into 6 groups (N = 12/group): 3 control and 3 septic groups depending on the euthanasia time (24 h, 48 h, 72 h). Septic groups underwent cecal ligation and puncture (CLP) to induce peritonitis, while control groups had a sham operation. Hematological tests were performed in serum for immune biomarkers; immunohistochemistry, morphometry and qRT-PCR analysis were used on both kidney and intestine tissues to evaluate the expression of TLR 2, 3, 4 and 7 in a septic process. At the end of each experimental period, we found that TLRs 2, 3, 4 and 7 were expressed in both tissues but there were differences between those at various time points. Also, we found that mRNA levels were significantly higher in qRT-PCR evaluation in septic groups than control groups in both kidney and intestinal tissues (p < 0.05); showing a steady increase in the septic groups as the time to euthanasia was prolonged (p < 0.05). Overall, our study provides a suggestion that TLRs 2, 3, 4 and 7 are highly expressed in the kidneys of septic mice and especially that these TLRs are sensitive and specific markers for sepsis. Finally, our study supports the diagnostic importance of TLRs in AKI and provides an insight on the contribution of septic mice models in the study of multi organ dysfunction syndrome in general.

Background Despite the improvements in the early detection and treatment of non-metastatic esophageal cancer, more than half of patients undergoing a curative treatment for esophageal cancer will develop recurrence within three years. The prognosis of these patients is poor. However, a wide range in overall survival has been reported, depending on the pattern of recurrence, and no optimal treatment strategy following recurrence has yet been uniformly accepted. Aim In this article, we aimed to systematically review the literature for the role of surgical resection of metachronous distant metastasis following primary treatment of esophageal cancer. Furthermore, we discuss possible factors that could possibly predict which patients may benefit from a surgical approach. A comprehensive literature search was conducted in PubMed using combinations of keywords. Results Patients with recurrence may benefit of a multimodality treatment. Regarding the isolated recurrence of esophageal cancer in solid visceral organs, operative intervention has been proposed as a treatment that may offer a survival benefit in an individual basis. No definitive conclusions regarding the potential survival advantage offered by the surgical treatment of solitary recurrent lesions can be drawn. However, recent improvements in surgical treatment and optimization of perioperative management guarantee an acceptable operative risk, making surgical resection of solitary recurrence lesions a considerable therapeutic option. Conclusions It can be conferred from the available studies that the surgical treatment of isolated recurrence from esophageal cancer may offer a survival benefit for properly selected patients. Prospective, multicenter studies might be useful to gain a better insight into those factors that affect selection of patients to take benefit from an operative intervention.

Recent advances in surgical techniques have broadened the indications of surgical management of liver malignancies. Intraoperative bleeding is one of the known predictors of postoperative outcomes following liver surgery, signifying the importance of vascular control during liver resection. Furthermore, preservation of future liver remnant plays a critical role in prevention of post-hepatectomy liver failure as one of the main causes of postoperative morbidity and mortality. Glissonian approach liver resection offers an effective method for vascular inflow control while protecting future liver remnant from ischemia-reperfusion injury. Several studies have demonstrated the feasibility of Glisson’s pedicle resection technique in modern liver surgery with an acceptable safety profile. Moreover, with increasing popularity of minimally invasive surgery, laparoscopic liver resection via Glissonian approach has been shown to be superior to standard laparoscopic hepatectomy. Herein, we systematically review the role of Glissonian approach hepatectomy in current practice of liver surgery, highlighting its advantages and disadvantaged over other methods of vascular control.

[...]oncoplastic techniques did not seem to improve the cosmetic outcome even many months into the postoperative period. [...]one cannot avoid noticing that the oncoplastic group was heterogeneous from the technical point of view, with about two thirds of it being adjacent tissue transfer.

PurposePost-sternotomy deep sternal wound infection (DSWI) is a severe complication of cardiac surgery. The introduction of omental and muscle flaps has resulted in a significant decrease in morbidity and mortality. In this article, we present the findings for a series of 55 consecutive patients with DSWI treated using an alternative bi-pectoral musculofascial flap technique.MethodsThe patients were stratified into two groups (one-or two-stage intervention). Patients with septic wounds initially underwent debridement and wound treatment, while vacuum therapy was used in a subset of the subjects. All patients were treated with wound debridement and bi-pectoral advancement flap reconstruction.Results30-day mortality was 5.4 %. Most patients (72 %) were treated in two stages, while vacuum therapy was used in 20 % of the patients. The mean number of hospitalization days was 8 and 12 for the one- and the two-stage groups, respectively. Reconstruction was successful in all but three patients, each of whom developed recurrent infection. No major morbidity was reported at a mean follow-up of 82 months with excellent functional and aesthetic outcomes.ConclusionsPectoralis-major muscle flaps remain relevant in the modern management of post-sternotomy mediastinitis. The addition of an omental flap should be considered in cases in which the lower sternum is involved. Prompt diagnosis and a meticulous surgical technique ensure favorable results for the majority of patients.

Roux-en-Y hepaticojejunostomy (RYHJ) is currently considered as the definitive treatment for iatrogenic bile duct injuries and the principal representative of biliary diversion procedures. This technique has met many milestones of extensive evolution, particularly the last years of concomitant technological evolution (laparoscopic/robotic approach). Anastomotic strictures and leaks, which may have deleterious effects on the survival and quality of life of a patient with biliary obstruction of any cause, made the need of the development of a safe and efficient RYHJ compulsory. The aim of this technical analysis and the juxtaposed discussions is to elucidate with the most important milestones and technical tips and tricks all aspects of a feasible and reliable RYHJ technique that is performed in our center for the last 25 years in around 400 patients.
