Cumulative dissipated energy (CDE) was used with Infiniti((R)) Vision System (Alcon Labs) as an energy delivery guide to compare four different phaco techniques and phaco settings. The supracapsular phaco technique and burst mode is known for efficiency and surgery is faster compared with the old phaco unit. In this study, we found that supracapsular phaco with burst mode had the least CDE in both cataract and nuclear sclerosis cataract with the new Infiniti((R)) unit. We suggest that CDE can be used as one of the references to modify technique and setting to improve outcome for surgeons, especially for new surgeons.

Examination of the results and describing the technique of manual small incision extracapsular cataract extraction on patients with advanced cataracts in urban Australia. A descriptive case series. Thirty-eight patients at three public hospitals, one tertiary and two secondary ophthalmic units in urban Australia. Forty eyes with dense mature cataracts with hand movement vision or worse underwent a planned manual small incision extracapsular cataract extraction instead of traditional phaco-emulsification. Postoperative visual aquity, surgically induced astigmatism and complications. Seventy-eight per cent of patients had an uncorrected visual acuity of 6/12 or better on the first postoperative day. Eighty-three per cent of patients had a distance corrected visual acuity of 6/9 or better 3 months postoperatively. One case was complicated by a posterior capsule rupture. No cases of endophthalmitis were reported. The summated vector mean of the surgically induced astigmatism was 0.089D at 93°. Manual small incision extracapsular cataract extraction is an efficacious cataract surgery technique with good visual outcome and is a safe alternative to phaco-emulsification in suitable cases in a first-world setting. © 2014 Royal Australian and New Zealand College of Ophthalmologists.

Comparison of peristaltic and Venturi pumps in bimanual microincision phacoemulsification on the success of the cataract surgery by using sleeveless phaco tip. Bimanual microincision phacoemulsification was done in 49 eyes using a 1.4-mm temporal clear corneal incision. A peristaltic pump was used in 23 eyes, and a Venturi pump was used in 26 eyes for phacoemulsification. Intraoperative complications, anterior chamber stability, and mean duration of surgery were recorded. Duration of surgery was shorter in the Venturi pump group. Anterior chamber stability could not be established in 17 eyes in the peristaltic pump group; it was established in all eyes in the Venturi pump group. Corneal burns were observed in two eyes in the peristaltic pump group and no eyes in the Venturi pump group. Use of a Venturi pump system and a vented gas-forced infusion system can significantly shorten surgery time and reduce risk of thermal burns.

The aim of the present study was to evaluate the effects of femtosecond laser-assisted cataract surgery (FLACS) and phacoemulsification on corneal biomechanics using corneal visualization Scheimpflug technology. The medical records of 50 eyes from 50 patients who received phacoemulsification and intraocular lens implantation because of age-related factors between June 2014 and September 2014 were retrospectively analyzed. FLACS was used in 12 eyes (FLACS group), and conventional phacoemulsification in 38 eyes (PHACO group). The evaluation of corneal biomechanical parameters included the first/second applanation time (A-time1/A-time2), the first/second applanation length (A-length1/A-length2), corneal velocity during the first/second applanation moment (Vin/Vout), highest concavity time, highest concavity-radius (HC-radius), peak distance (PD), deformation amplitude (DA), central corneal thickness (CCT), and intraocular pressure (IOP). The differences in A-length1/A-length2, IOP, CCT, PD, and DA were significant in the PHACO group between those before, 1 week after, and 1 month after surgery. No significant differences in corneal biomechanical parameters were found between those at 1 month after surgery and before surgery. There were significant differences in IOP and CCT in the FLACS group between those before, 1 week after, and 1 month after surgery. There were no significant differences in the other corneal biomechanical parameters. No significant differences were found in corneal biomechanical parameters between those 1 month after surgery and before surgery. There were significant differences in A-length1/A-length2, CCT, PD, and DA between the two groups at 1 week after surgery. There were no significant differences in corneal biomechanical parameters between the two groups at 1 month after surgery. In conclusion, the effect of FLACS on corneal biomechanics is smaller than that of phacoemulsification. The corneal biomechanical parameters are restored to

Cataract surgeons outperform medical students in Eyesi virtual reality cataract surgery: evidence for construct validity.

To investigate construct validity for modules hydromaneuvers and phaco on the Eyesi surgical simulator. Seven cataract surgeons and 17 medical students performed capsulorhexis, hydromaneuvers, phaco, navigation, forceps, cracking and chopping modules in a standardized manner. Three trials were performed on each module (two on phaco) in the above order. Performance parameters as calculated by the simulator for each trial were saved. Video recordings of the second trial of the modules capsulorhexis, hydromaneuvers and phaco were evaluated with the modified Objective Structured Assessment of Surgical Skill (OSATS) and Objective Structured Assessment of Cataract Surgical Skill (OSACSS) tools. Cataract surgeons outperformed medical students with regard to overall score on capsulorhexis (p < 0.001, p = 0.035, p = 0.010 for the tree iterations, respectively), navigation (p = 0.024, p = 0.307, p = 0.007), forceps (p = 0.017, p = 0.03, p = 0.028). Less obvious differences in overall score were found for modules cracking and chopping (p = 0.266, p = 0.022, p = 0.324) and phaco (p = 0.011, p = 0.081 for the two iterations, respectively). No differences in overall score were found on hydromaneuvers (p = 0.588, p = 0.503, p = 0.773), but surgeons received better scores from the evaluations of the modified OSATS (p = 0.001) and OSACSS (capsulorhexis, p = 0.003; hydromaneuvers, p = 0.017; phaco, p = 0.001). Construct validity was found on several modules previously not investigated (phaco, hydromaneuvers, cracking and chopping, navigation), and our results confirm previously demonstrated construct validity for capsulorhexis and forceps modules. Interestingly, validation of the hydromaneuvers module required OSACSS video evaluation tool. A further development of the scoring system in the simulator for the hydromaneuvers module would be advantageous and make training and evaluation of progress more accessible and immediate. © 2012 The Authors.

We have developed a virtual reality (VR) simulator for phacoemulsification (phaco) surgery. The current work aimed at developing a performance index that characterizes the performance of an individual trainee. We recorded measurements of 28 response variables during three iterated surgical sessions in 9 subjects naive to cataract surgery and 6 experienced cataract surgeons, separately for the sculpting phase and the evacuation phase of phacoemulsification surgery. We further defined a specific performance index for a specific measurement variable and a total performance index for a specific trainee. The distribution function for the total performance index was relatively evenly distributed both for the sculpting and the evacuation phase indicating that parametric statistics can be used for comparison of total average performance indices for different groups in the future. The current total performance index for an individual considers all measurement variables included with the same weight. It is possible that a future development of the system will indicate that a better characterization of a trainee can be obtained if the various measurements variables are given specific weights. The currently developed total performance index for a trainee is statistically an independent observation of that particular trainee.

The aim of this study was to review the capability of virtual reality simulators in the application of phacoemulsification cataract surgery training. Our review included the scientific publications on cataract surgery simulators that had been developed by different groups of researchers along with commercialized surgical training products, such as EYESI® and PhacoVision®. The review covers the simulation of the main cataract surgery procedures, i.e., corneal incision, capsulorrhexis, phacosculpting, and intraocular lens implantation in various virtual reality surgery simulators. Haptics realism and visual realism of the procedures are the main elements in imitating the actual surgical environment. The involvement of ophthalmology in research on virtual reality since the early 1990s has made a great impact on the development of surgical simulators. Most of the latest cataract surgery training systems are able to offer high fidelity in visual feedback and haptics feedback, but visual realism, such as the rotational movements of an eyeball with response to the force applied by surgical instruments, is still lacking in some of them. The assessment of the surgical tasks carried out on the simulators showed a significant difference in the performance before and after the training.

To evaluate the efficacy of topical anesthesia with oxybuprocaïne 0.4% without intracameral lidocaïne as an alternative to peribulbar or retrobulbar anesthesia in cataract surgery. Fifty-eight patients (eighty-two eyes) were included in this study. All patients received topical anesthesia with oxybuprocaïne 0.4%. No intracameral lidocaïne was used at the start of the intervention. Seventy-five per cent of patients received oral sedation with lorazepam 2.5 mg. All surgery was done using a superior corneal incision and phacoemulsification followed by a foldable IOL implantation. Subjective pain was assessed at 4 intervals during surgery using a 4-point pain scale. All patients were evaluated for intraoperative eye motility and blepharospasm. Patient and surgeon satisfaction was measured with a 4-point satisfaction scale. 15% of patients experienced mild pain during phaco and 43% had mild pain during corneal suturing. No patient had severe pain during the operation. In 4% of patients, intracameral lidocaïne was used to relieve pain. The surgeon and patient satisfaction was high. No eye movements or blepharospasm were recorded in 75% and 62% of cases respectively. No serious complications occurred. Topical anesthesia is a safe and effective alternative to peribulbar and retrobulbar anesthesia in corneal cataract surgery for the experienced surgeon.

Near-death experience (NDE) is a complex subjective experience, which may include affective elements such as a sense of peacefulness, paranormal components such as a sensation of floating out of the body, and a perception of being in a dark tunnel and seeing a brilliant light. It is usually reported to occur in association with a wide range of life-threatening situations, as for instance, cardiopulmonary resuscitation. We report on an episode of NDE that occurred in a 12-year-old boy who underwent a general anesthesia for an elective uncomplicated surgery. To our knowledge, this is the first case of NDE in a child that has been reported in this context.

Glutaric aciduria type 1 (GA1) is an autosomal recessive rare disorder caused by mutations in the GCDH gene resulting in deficiency of glutaryl-CoA dehydrogenase, leading to accumulation of the amino acids lysine, hydroxylysine and tryptophan and other metabolites. The phenotypic spectrum of disease is broad. Stress caused by infection and fever and possibly pregnancy may lead to worsening of the signs and symptoms, often with uncertain recovery.We describe a case of a female patient with GA1 who had two clinically uneventful pregnancies.At the age of 11 she was diagnosed with GA1 by family screening. The cultured skin fibroblast showed reduced glutaryl-CoA dehydrogenase activity (0.16 mg protein per min).The initial diagnostic urine glutaric acid level for this patient was 1,784 μmol/mmol creatinine. Mutation analysis showed compound heterozygosity for the p.(Gly185Arg), c.553G>A in exon 7 and p.(Arg402Trp), c.1204C.T in exon 11 mutations of the GCDH.Her pregnancy at the age of 23 was complicated by pre-eclampsia and required treatment with beta-blockers. Four years later the second pregnancy was uncomplicated. The management plan during the caesarean section included intravenous dextrose and lipid infusions. The patient rapidly recovered from both surgeries.Both babies have had normal development to date. On newborn screening, plasma acylcarnitine showed a transient increase in glutarylcarnitine, and the urine organic acid analysis showed a trace of 3-hydroxyglutarylcarnitine, likely to be of maternal transfer.The multidisciplinary team, consisting of metabolic, dietetic and obstetric care providers, have responsibility to ensure the risk of acute decompensation in pregnant GA1 women is minimal.

AIM To describe a new surgical technique for managing dislocated sclerotic cataractous lens. METHODS Six patients with advanced posteriorly dislocated cataracts were operated at a tertiary care centre and analyzed retrospectively. After standard 3 port 23 G pars plana vitrectomy and perfluorocarbon liquid (PFCL) injection, the dislocated white cataract was held with occlusion using phaco fragmatome and then chopped into smaller pieces with a sharp tipped chopper using 25 G chandelier endoilluminator. Each piece was emulsified individually. Following aspiration of PFCL, Fluid Air Exchange was done in all the cases and surgery completed uneventfully. RESULTS Best corrected visual acuity (BCVA) in all the patients was better than 6/12 after one month of follow up. No serious complications were noted till minimum 6mo of follow up. CONCLUSION Four port posterior segment nucleotomy with a chandelier endoilluminator, fragmatome and a chopper appears to be a safe, easy and effective procedure for managing dislocated sclerotic cataractous nuclei. Ultrasonic energy used and adverse thermal effects of the fragmatome on the sclera may be lesser. PMID:26309887

To compare initial glaucoma therapy with medications and trabeculectomy in southern India. Patients aged ≥ 30 years newly diagnosed with glaucoma were randomized to trabeculectomy with 5-fluorouracil or medical therapy. Subjects with best-corrected vision <6/18 due to cataract underwent phacoemulsification (phaco/intraocular lens, IOL). Intraocular pressure (IOP), vision and visual function were assessed at 12 months. Patients assigned to medications and surgery received the expected therapy in 86% (172/199) and 64% (126/199) of cases, respectively. Forty patients (20%) assigned to surgery refused any treatment and 33 (17%) received medications. Among 199 patients randomized to medications, 52 (26.1%) underwent phaco/IOL, as did 89/199 (43.7%) of patients randomized to trabeculectomy. Baseline parameters of the two groups did not differ, nor did 1-year follow-up rates (medication 65%, trabeculectomy 58%, P = 0.15). Final IOP was lower with randomization to trabeculectomy (16.3 ± 5.1 mmHg) than medication (18.8 ± 6.7 mmHg, P < 0.0001). In regression models, randomization to trabeculectomy (P < 0.0001) was associated with lower IOP, and simultaneous trabeculectomy and cataract surgery was associated with higher IOP (P = 0.008) than trabeculectomy alone. Subjects receiving Phaco/IOL had significantly better final acuity (P < 0.0001) and visual function (P = 0.035), despite concurrent glaucoma treatment. Final visual acuity was worse in those receiving trabeculectomy in addition to cataract surgery, but this was of borderline significance (P = 0.06). Trabeculectomy lowered IOP significantly more than medical treatment, but with slightly greater loss of visual acuity. Combined phaco/IOL and trabeculectomy improved visual acuity with substantial IOP lowering.

The aim was to assess the impact of cataract surgeries in reducing visual disabilities and factors influencing it at three institutes of India. A retrospective chart review was performed in 2013. Data of 4 years were collected on gender, age, residence, presenting a vision in each eye, eye that underwent surgery, type of surgery and the amount the patient paid out of pocket for surgery. Visual impairment was categorized as; absolute blindness (no perception of light); blind (<3/60); severe visual impairment (SVI) (<6/60-3/60); moderate visual impairment (6/18-6/60) and; normal vision (≥6/12). Statistically analysis was performed to evaluate the association between visual disabilities and demographics or other possible barriers. The trend of visual impairment over time was also evaluated. We compared the data of 2011 to data available about cataract cases from institutions between 2002 and 2009. There were 108,238 cataract cases (50.6% were female) that underwent cataract surgery at the three institutions. In 2011, 71,615 (66.2%) cases underwent surgery. There were 45,336 (41.9%) with presenting vision < 3/60 and 75,393 (69.7%) had SVI in the fellow eye. Blindness at presentation for cataract surgery was associated to, male patients, Institution 3 (Dristi Netralaya, Dahod) surgeries after 2009, cataract surgeries without Intra ocular lens implant implantation, and patients paying <25 US $ for surgery. Predictors of SVI at time of cataract surgery were, male, Institution 3 (OM), phaco surgeries, those opting to pay 250 US $ for cataract surgeries. Patients with cataract seek eye care in late stages of visual disability. The goal of improving vision related quality of life for cataract patients during the early stages of visual impairment that is common in industrialized countries seems to be non-attainable in the rural India.

To evaluate the clinical outcome of the femtosecond laser-assisted cataract surgery (FLACS) in our first 300 cases. In this retrospective study, the study group comprised 300 cases (300 eyes) in which FLACS was done. The control group comprised 300 cases (300 eyes) in which phacoemulsification was performed. The steps of the FLACS included capsulotomy, lens fragmentation, corneal incisions, and creation of incisions within the peripheral cornea to aid the correction of pre-existing astigmatism. After the FLACS, 2.2-mm coaxial micro-incision phacoemulsification and implantation of an intraocular lens were operated. The preoperative best corrected visual acuity (BCVA) and postoperative uncorrected visual acuity (UCVA), the cumulative dissipated energy (CDE) of the phacoemulsification, and the parameters of the FLACS, including the docking time, the suction time and the laser time, were recorded. The complications of the FLACS were analyzed. The FLACS was successfully completed in 99.33% of the cases. The docking time was (24.6 ± 16.8) sec, the suction time was (101.27 ± 20.09) sec, and the laser time was (23.3 ± 5.5) sec. The most common complications of the FLACS included suction break (7/300, 2.33%), subconjunctival hemorrhage (58/300, 19.33%), pupillary constriction (47/300, 15.67%), incision at a wrong site (13/300, 4.33%), anterior capsular tag (17/300, 5.67%), decentration of the capsulorhexis (11/300, 3.67%), failure to split the lens nucleus (5/300, 1.67%), and posterior capsular ruptures (1/300, 0.33%). The CDE was 5.52 ± 5.18 in the FLACS group and 8.37 ± 7.91 in the traditional phaco group (P < 0.05). The UCVA was 0.12 ± 0.08 and 0.13 ± 0.11 at 1 month after the FLACS and traditional phaco, respectively (P > 0.05). Compared with the conventional phacoemulsification surgery, the FLACS can achieve less CDE and better early postoperative visual acuity. Long-term effects remain to be investigated.

To assess the impact of sequential and combined surgery [cataract surgery and 23-gauge pars plana vitrectomy (PPV) with peeling] on corneal endothelium cell density (CED) and corneal biomechanical characteristics. Phakic eyes with epiretinal membrane (ERM) were prospectively allocated to (i) cataract surgery and subsequent PPV (CAT group), (ii) PPV and subsequent cataract surgery (VIT group) or (iii) phacovitrectomy (COMBI group). Eyes were examined at baseline, 1 month after each surgery, and at 3 and 12 months follow-up. Corneal endothelium cell density (CED) was assessed with non-contact specular microscopy. Pachymetry [central cornea thickness (CCT)], keratometry and cornea volume (CV) were measured with Pentacam Scheimpflug camera. Primary outcome was change in CED after 12 months; secondary outcomes were changes in CCT and CV after 12 months. Sixty-two eyes were enrolled and allocated to the three groups. The mean preoperative CED was 2776, 2794 and 2653 cells/mm 2, which decreased significantly at 12 months by 15.3, 20.0 and 19.3% in the CAT, VIT and COMBI group. There was no significant difference in percentage cell loss between the groups at final follow-up. The CED decreased significantly after cataract surgery, but was unaffected by PPV. Central cornea thickness (CCT) increased by 10 μm (p = 0.005) and CV by 1.38 mm 3 (2.3%, p < 0.001) in the COMBI group. There were no significant differences in CCT or CV between the groups at final follow-up. Combined and sequential surgery in ERM leads to a small decrease in CED. Performing cataract surgery before, after or in combination with vitrectomy did not make any significant difference with respect to final CED, CCT or CV. © 2017 Acta Ophthalmologica Scandinavica Foundation.

To investigate the correlation in performance of cataract surgery between a virtual-reality simulator and real-life surgery using two objective assessment tools with evidence of validity. Cataract surgeons with varying levels of experience were included in the study. All participants performed and videorecorded three standard cataract surgeries before completing a proficiency-based test on the EyeSi virtual-reality simulator. Standard cataract surgeries were defined as: (1) surgery performed under local anaesthesia, (2) patient age >60 years, and (3) visual acuity >1/60 preoperatively. A motion-tracking score was calculated by multiplying average path length and average number of movements from the three real-life surgical videos of full procedures. The EyeSi test consisted of five abstract and two procedural modules: intracapsular navigation, antitremor training, intracapsular antitremor training, forceps training, bimanual training, capsulorhexis and phaco divide and conquer. Eleven surgeons were enrolled. After a designated warm-up period, the proficiency-based test on the EyeSi simulator was strongly correlated to real-life performance measured by motion-tracking software of cataract surgical videos with a Pearson correlation coefficient of -0.70 (p = 0.017). Performance on the EyeSi simulator is significantly and highly correlated to real-life surgical performance. However, it is recommended that performance assessments are made using multiple data sources. © 2016 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

To evaluate the effect of three different combinations of tip designs and infusion systems in torsional phacoemulsification (INFINITI and CENTURION) in patients with cataract. According to the manufacturer, two unique improvements in the Centurion are: active fluid dynamic management system and use of an intrepid balanced tip. The study specifically aimed to evaluate the beneficial effects, if any, of change in tip design and infusion system individually and in combination on both per-operative parameters as well as endothelial health over 6 months. One hundred and twenty six consenting patients of grade 4.0-6.9 senile cataract were randomized into three groups for phacoemulsification: Group A ( n  = 42): Gravity fed infusion system and 45 0 Kelman miniflared ABS phaco tip; Group B ( n  = 42): intraocular pressure (IOP) based infusion system and 45 0 Kelman miniflared ABS phaco tip; Group C ( n  = 42): IOP based infusion system and 45 0 Intrepid balanced phaco tip. The cumulative dissipated energy (CDE), estimated fluid usage (EFU) and total aspiration time (TAT) were compared peroperatively. The endothelial parameters were followed up postoperatively for six months. The three arms were matched for age ( p  = 0.525), gender ( p  = 0.96) and grade of cataract ( p  = 0.177). Group C was associated with significant reductions in CDE ( p  = 0.001), EFU ( p  < 0.0005) as well as TAT ( p  = 0.001) in comparison to the other groups. All three groups had comparable baseline endothelial cell density ( p  = 0.876) and central corneal thickness ( p  = 0.561). On post-operative evaluation, although all groups were comparable till 3 months, by 6 months, the percentage losses in endothelial cell density were significantly lower in group C as compared to the other groups. Use of an IOP based phacoemulsification system in association with use of the Intrepid balanced tip reduces the CDE, EFU and TAT in comparison to a gravity fed system with a mini flared

Cataract surgery in a case of carotid cavernous fistula

A carotid-cavernous fistula (CCF) is an abnormal communication between the cavernous sinus and the carotid arterial system. The ocular manifestations include conjunctival chemosis, proptosis, globe displacement, raised intraocular pressure and optic neuropathy. Although management of CCF in these patients is necessary, the ophthalmologist may also have to treat other ocular morbidities such as cataract. Cataract surgery in patients with CCF may be associated with many possible complications, including suprachoroidal hemorrhage. We describe cataract extraction surgery in 60-year-old female with bilateral spontaneous low-flow CCF. She underwent phacoemulsification via a clear corneal route under topical anesthesia and had an uneventful postoperative phase and recovered successfully. Given the various possible ocular changes in CCF, one must proceed with an intraocular surgery with caution. In this communication, we wish to describe the surgical precautions and the possible pitfalls in cataract surgery in patients with CCF. PMID:25370401

The first patient was a 58-year-old female who presented to our hospital with abdominal pain and vomiting; she had no history of abdominal surgery. Enhanced computed tomography revealed strangulation ileus due to an internal hernia. The second patient was a 36-year-old male who presented to our hospital with abdominal pain and no history of abdominal surgery. Enhanced computed tomography indicated transomental hernia. Emergency laparoscopic surgery in both patients revealed incarcerated bowel loops through defects in the greater omentum. The bowel segments were laparoscopically released, and the patients were uneventfully discharged on postoperative Days 4 and 8. Laparoscopic surgery is useful for the diagnosis and treatment of small bowel obstruction due to transomental hernia through the greater omentum.

Most regional anesthesia in breast surgeries is performed as postoperative pain management under general anesthesia, and not as the primary anesthesia. Regional anesthesia has very few cardiovascular or pulmonary side-effects, as compared with general anesthesia. Pectoral nerve block is a relatively new technique, with fewer complications than other regional anesthesia. We performed Pecs I and Pec II block simultaneously as primary anesthesia under moderate sedation with dexmedetomidine for breast conserving surgery in a 49-year-old female patient with invasive ductal carcinoma. Block was uneventful and showed no complications. Thus, Pecs block with sedation could be an alternative to general anesthesia for breast surgeries. PMID:28932733

To report a case of delayed presentation of a severed acrylic single-piece intraocular lens (IOL) haptic fragment causing corneal edema after uneventful phacoemulsification surgery. An 85-year-old male presented with inferior corneal decompensation six months after a reportedly uneventful phacoemulsification in his left eye. A distal haptic fragment of an acrylic single-piece posterior chamber intraocular lens was found in the inferior anterior chamber angle. Intraoperative examination revealed that the dislocated fragment originated from the temporal haptic, the remainder of which was adherent to the anterior surface of the capsular bag. The clipped edge of the haptic fragment showed a clean, flat surface, suggesting it was severed by a sharp object. The findings were considered consistent with cutting of the fragment during implantation presumably from improper lens loading, improper implantation technique, or defective implantation devices. This is the first case report of a foldable acrylic intraocular lens severed during routine uncomplicated cataract surgery that was not noted at the time of the surgery or in the immediate postoperative period. Delayed presentation of severed IOL fragments should be considered in cases of late onset corneal edema post-operatively, when other causes have been ruled out. Careful implantation technique and thorough examination of the intraocular lens after implantation to assess for lens damage intraoperatively is essential to avoid such rare complications.

To present a case of bilateral methicillin-resistant Staphylococcus aureus (MRSA) keratitis after photorefractive keratectomy (PRK). Retrospective chart review. RESULTS A 26-year-old female internal medicine resident underwent an uneventful bilateral PRK. After the procedure, the patient was fit with a bandage contact lens and was prescribed tobramycin 0.3%, fluorometholone 0.1%, and diclofenac sodium 0.1% four times per day. Postoperatively, corneal ulcers were noted in each eye, and the patient was referred for a consultation. Gram stain showed gram-positive cocci. The patient immediately started using vancomycin, 35 mg/mL every half hour, and ofloxacin 0.3% every hour around the clock. Forty-eight hours later, corneal and lid cultures were positive for MRSA. Three months after the infection, there was approximately 40% corneal thinning in the right eye and 10% thinning in the area of the corneal ulceration of the left eye. The patient is awaiting corneal transplantation of the right eye. To our knowledge, this represents the first reported case of bilateral MRSA keratitis after PRK. Methicillin-resistant S. aureus is a potentially serious infectious agent after PRK and may be associated with exposure to a hospital setting. For patients who have had extensive exposure to a hospital environment and are undergoing ocular surgery, we recommend prophylaxis against MRSA. To treat a possible MRSA keratitis, we suggest starting a fourth-generation topical fluoroquinolone every 30 minutes, alternating it with vancomycin 50 mg/mL every 30 minutes, and discontinuing steroid use. A high degree of suspicion coupled with rapid and appropriate treatment may result in improved visual recovery.

Background To study phacoemulsification probe shaft/wound and corneal surface/tip temperatures in vivo during longitudinal, torsional and combined phacoemulsification modes and their relationship to machine parameters. Design This was a prospective study at Chaithanya Eye Hospital and Research Institute, Trivandrum, India (tertiary). Participants Twenty-two eyes of 22 patients were randomized into six groups depending on the grade of nuclear sclerosis (NS) and the type of ultrasound used: Group 1, torsional in NS2; Group 2, torsional in NS3; Group 3, torsional with intermittent longitudinal in NS2; Group 4, torsional with intermittent longitudinal in NS3; Group 5, longitudinal in NS2; Group 6, longitudinal in NS3. Methods Patients underwent phacoemulsification by torsional, longitudinal or combined modalities. A thermal camera was used to measure phaco probe temperatures. Main outcome measures The mean probe shaft and tip temperatures were documented for different ultrasound modalities. Results The mean shaft and tip temperatures were: Group 1, 29.22°C±0.71°C and 28.4°C±0.88°C; Group 2, 32.12°C±0.62°C and 31.88°C±0.84°C; Group 3, 30.25°C±0.71°C and 29.35°C±0.62°C; Group 4, 31.95°C±0.65°C and 32.01°C±1.31°C; Group 5, 23°C and 27.6°C and Group 6, 23°C and 29.68°C, respectively. In all groups using longitudinal ultrasound, the phaco tip surface temperatures were higher than the shaft temperatures, except in Group 3. Shaft temperatures were higher than tip temperatures in cases using torsional phaco, except in Group 4. The mean temperature difference between groups was significant only for shaft temperatures (P=0.001). On thermal imaging, for torsional phaco, the rise in temperature of the probe from shaft to tip was dependent on the amplitude of ultrasound applied (P=0.009). Conclusion The shaft temperatures were higher than over the phaco tip during torsional phacoemulsification. PMID:28184151

To compare the actual vacuum pressure at the end of an aspiration bypass system (ABS) phaco tip and a conventional tip in conditions similar to those during human cataract surgery. Kangbuk Samsung Hospital, Seoul, Korea. A 4.0 mm diameter rubber eraser ball was inserted in a phacoemulsified swine eye and engaged to a phaco tip. With a vacuum pressure of 300 mm Hg, the eraser ball was pulled in the opposite direction with the phaco tip. The pulling power separating the eraser ball from the phaco tip was measured using the volume of water dripped into a container connected to the eraser ball. Measurements were taken with an Infiniti ABS tip and 2 conventional tips: Sovereign (conventional tip S) and Infiniti (conventional tip I). Measurements were taken alternatively at random in the same eye. The mean pulling power was 17.35 mL +/- 5.01 (SD) with conventional tip S and 16.85 +/- 4.45 mL with conventional tip I. The mean pulling power of the ABS tip was 13.35 +/- 4.32 mL, which was a mean 20.8% lower than that of conventional tip I (P = .016) and 23.1% lower than that of conventional tip S (P = .010). The actual vacuum pressure of the phaco tip was significantly influenced by the presence of the ABS hole. To compensate for the decrease in actual vacuum pressure, surgeons should be aware of the characteristics of the ABS tip being used and change the standard settings accordingly.

A 42-year-old, obese woman was admitted to our hospital 3 h after the sudden development of abdominal pain. Her umbilical region was swollen and she was diagnosed with incarceration of an umbilical hernia by computed tomography. Although we tried, we were unable to reduce the hernia with a manipulative procedure. We decided to perform an emergency laparoscopy. Once general anesthesia was induced, we achieved hernia reduction. From a laparoscopic view, the portion of strangulated small intestine was neither necrotic nor perforated. The size of the hernial orifice was ∼2 × 2 cm, and thus, we selected a 12 × 12 cm composite mesh to cover the hernia defect by at least 5 cm in all directions. The surgical procedure was uneventful and the total operation time was 112 min. The patient recovered uneventfully and was discharged on postoperative day 9. She remains free of recurrence 20 months after surgery. PMID:25672973

From January 2013 to January 2015, 19 patients of traumatic hemothorax with hemorrhagic shock were treated in our department by thoracoscopic surgery combined with autologous blood transfusion. This study retrospectively analyzed the therapeutic effect and shared our experience. The average amount of blood transfused back was 662.41 ml ± 269.15 ml. None of the patients developed transfusion reaction and were all discharged uneventfully. Thoracoscopic surgery combined with autologous blood trans- fusion is effective in the rescue of patients with progressive hemothorax and hemorrhagic shock. When corresponding indications are well managed, treatment for these patients is quicker, safer, and more effective.

Staple line and anastomotic leakages are life-threatening complications after bariatric surgery. Upper gastrointestinal (GI) tract X-ray examination with oral administration of a water-soluble contrast agent can be used to detect leaks. The aim of this study was to evaluate the impact of routine upper GI tract fluoroscopy after primary bariatric surgery. Between January 2009 and December 2014 a total of 658 bariatric interventions were carried out of which 442 were primary bariatric operations. Included in this single center study were 307 sleeve gastrectomies and 135 Roux-en-Y gastric bypasses. Up to December 2012 upper GI tract fluoroscopy was performed routinely between the first and third postoperative days and the detection of leakages was evaluated. In the investigation period 8 leakages (2.6 %) after sleeve gastrectomy, 1 anastomotic leakage in gastrojejunostomy and 1 in jejunojejunostomy after Roux-en-Y gastric bypass occurred. All patients developed clinical symptoms, such as abdominal pain, tachycardia or fever. In one case the leakage was detected by upper GI fluoroscopy and in nine cases radiological findings were unremarkable. No leakages were detected in asymptomatic patients. Routine upper GI fluoroscopy is not recommended for uneventful postoperative courses after primary bariatric surgery.

Testicular benign tumors are very rare (< 5%). Testicular Angiofibroma (AF) is one of those, however the gold standard of treatment and follow-up is still unclear. A 47 years-old man with only one functioning testis was referred to our clinic for a palpable right testicular mass and atrophic contralateral testis. Patient underwent testis-sparing surgery with inguinal approach and intraoperative frozen sections examination with diagnosis of AF. Final histology confirmed AF. Post-operative follow-up was uneventful. Clinical and ultrasonographic follow-up was negative after 8 months. We report a conservative surgery in a patient with AF of the solitary testis. AF is a benign para-testicular fibrous neoplasm that could be misinterpreted as malignant tumor and treated with orchiectomy. Testis-sparing surgery is recommended in this case with intraoperative pathological examination. The excision of the mass is enough but in front of a possible recurrence a long follow-up is advisable.

An experimental study to measure the heat profile of the phacoemulsification (phaco) tip using standard continuous phaco and hyperpulse phaco with and without waveform power modulation in the Millennium Microsurgical System with Custom Control Software (CCS). The phaco tip was imaged in air using a thermal camera. The highest temperature was measured 15 s after application of phaco power. Continuous, hyperpulse and waveform power modulations of the Millennium Microsurgical System were used with different power settings (20, 50 and 100 %) and duty cycles (40, 60 and 90 %), with the irrigation turned on and off. Using continuous phaco with the irrigation on, the phaco tip temperature remains <28.0 °C. With irrigation off, the temperature is higher compared to irrigation on but still remains <45.0 °C. Comparing the temperatures for all three power modulations when irrigation is on, at each phaco power and duty cycle setting, the temperature of the phaco tip is highest with continuous phaco, followed by hyperpulse with rise time 1, then hyperpulse with rise time 2. When irrigation is off, the highest temperatures are recorded using the hyperpulse with rise time 2, followed by continuous phaco, then hyperpulse with rise time 1. Hyperpulse and waveform modulations reduce heat generation compared to the continuous mode when irrigation is turned on. Lower duty cycles and lower ultrasound power produce less heat at the phaco tip.

A 4-mo-old red fox (Vulpes vulpes) was found recumbent after a vehicular accident. Radiology revealed several limb fractures and the fox underwent surgery after 24 hr of initial stabilization. Premedication consisted of dexmedetomidine and morphine. Anesthesia was induced with ketamine and midazolam and maintained with isoflurane. Lidocaine, bupivacaine, and morphine were administered epidurally and further analgesia was provided with meloxicam. The heart rate and respiratory rate of the fox remained stable during surgery and, except for a mild hypothermia, the recovery from anesthesia was uneventful. The postoperative pain scores were low and the animal was transported to a rehabilitation facility and eventually released to the wild. The low pain scores postoperatively should be attributed to the successful application of epidural anesthesia and analgesia.

Delayed mesh exposure after tension-free vaginal tape (TVT) procedure is rare. We report a case of mesh exposure into the vagina and urethra that developed 10 years after TVT surgery. A 58-year-old postmenopausal woman presented with mixed urinary incontinence. She was investigated, and her stress urinary incontinence was cured with a TVT procedure 10 years ago. She was then scheduled follow-up annually. Two years postsurgery, a granulation tissue was observed and excised at the vaginal incision site. Vaginal examination 10 years postsurgery showed vaginal mesh erosion 0.5 cm from urethral meatus. Cystoscopy revealed concomitant urethral erosion at the posterior urethral wall. Mesh excision was performed, and urethra and vagina were repaired in layers. Postoperative recovery was uneventful. This finding shows that, although rare, complications can occur even after 10 years of TVT surgery.

This is the first report in the literature to describe removing war-related cardiothoracic shrapnel using video-assisted thoracoscopic surgery (VATS). War blast caused penetrating thoracic and extremity injuries in 30-year-old man. He was referred to our hospital after stabilization. Magnetic resonance imaging was required to evaluate brachial plexus injury. Large, penetrating shrapnel fragment in the right posterior chest wall, retained shrapnel in apex of the right lung, and another fragment in the pericardium were removed using VATS in staged approach. Postoperative period was uneventful. VATS is useful in managing complex, war-related cardiothoracic injuries.

This paper compares and evaluates the corneal morphological changes occurring after cataract surgery through a 2.2 mm corneal incision. We use two platforms for comparison and evaluation, transversal and torsional phacoemulsification. This study includes 139 consecutive cataractous eyes (nuclear color 2-4, according to the Lens Opacities Classification System III [LOCSIII]) of 82 patients undergoing cataract surgery through a 2.2 mm corneal incision. Two different phacoemulsification platforms were used and assigned randomly: we used the WhiteStar Signature(®) system with the Ellips™ FX transversal continuous ultrasound (US) mode for group I (mean age: 65.33 ± 6.97 years), and we used the Infiniti(®) system with the OZil(®) Intelligent Phaco (IP) torsional US mode for group II (mean age: 64.02 ± 7.55 years). The corneal endothelium and pachymetry were evaluated preoperatively and at 1 month postoperatively. Incision size changes were also evaluated. All surgeries were uneventful. Before intraocular lens implantation, the mean incision size was 2.24 ± 0.06 mm in both groups (P = 0.75). In terms of corneal endothelial cell density, neither preoperative (I vs II: 2304.1 ± 122.5 cell/mm(2) vs 2315.6 ± 83.1 cell/mm(2), P = 0.80) nor postoperative (I vs II: 2264.1 ± 124.3 cell/mm(2) vs 2270.3 ± 89.9 cell/mm(2), P = 0.98) differences between the groups were statistically significant. The mean endothelial cell density loss was 1.7% ± 1.6% and 2.0% ± 1.4% in groups I and II, respectively. Furthermore, no significant differences between groups I and II were found preoperatively (P = 0.40) and postoperatively (P = 0.68) in central pachymetry. With surgery, the mean increase in central pachymetry was 28.1 ± 23.6 μm and 24.0 ± 24.0 μm in groups I and II, respectively (P = 0.1). Ellips™ FX transversal and OZil(®) IP torsional phacoemulsification modes are safe for performing cataract surgery, inducing minimal corneal thickness and endothelial changes.

This purpose of this case series is to present the first four cases utilizing micro-phonosurgical instrumentation designed specifically for use with a semi-flexible 'robotic' system-the Medrobotics Flex system and to evaluate the accessibility and feasibility of this platform in the context of transoral robotic surgery (TORS) for laryngeal surgery. Four patients (3 female, 1 male; age range 49-79 years) were operated by the senior author at CHL-a tertiary hospital centre between 2016 and 2017. The 'robot' was deployed in all cases to assess its accessibility and ability to perform surgery in the larynx. All four patients were successfully treated using the system along with newly developed instrumentation specifically focused on phonosurgery. This series has demonstrated accessibility and ability for laryngeal surgery using a novel semi-rigid operator-controlled 'robotic' system. We encountered no device failures and were able to perform all the selected cases uneventfully.

Combined analysis of trabectome and phaco-trabectome outcomes by glaucoma severity

Prior glaucoma severity staging systems were mostly concerned with visual field function and retinal nerve fiber layer, but did not include intraocular pressure or medications to capture resistance to treatment. We recently introduced a simple index that combines pressure, medications, and visual field damage and applied it to stratify outcomes of trabectome surgery. In the analysis presented here, we combined data of trabectome alone and trabectome with same session cataract surgery to increase testing power and chances of effect discovery. This microincisional glaucoma surgery removes the primary resistance to outflow in glaucoma, the trabecular meshwork, and has been mostly used in mild glaucoma. Traditional glaucoma surgeries have a relatively high complication rate and have been reserved for more advanced disease stages. In the analysis presented here we include our data of trabectome combined with cataract surgery. This is a common practice pattern as both occur in the same age group with increasing frequency. For patients in higher glaucoma index (GI) groups, the intraocular pressure (IOP) reduction was 2.34+/-0.19 mmHg more than those in a GI group one level lower while holding everything else constant. Those who had undergone trabectome combined with phacoemulsification had an IOP reduction that was 1.29+/-0.39 mmHg less compared to those with trabectome alone. No statistically significant difference was found between genders and age groups while holding everything else constant. Hispanics had a 3.81+/-1.08 mmHg greater IOP reduction. Pseudoexfoliation and steroid glaucoma patients had an IOP reduction that was greater by 2.91+/-0.56 and 3.86+/-0.81 mmHg, respectively, than those with primary open angle glaucoma. These results suggest a role for trabectome-mediated ab interno trabeculectomy beyond mild forms of glaucoma. Additionally, the multifactorial glaucoma index demonstrates a role in staging patients when comparing glaucoma surgical modalities. PMID

To assess the alterations of the anterior chamber conditions including laser flare photometry after femtosecond laser-assisted cataract surgery (FLACS) compared to the manual phacoemulsification. Data of n=70 FLACS (mean age 67.2 ± 8.9 years) and n=40 manual phacoemulsification (mean age 69.5 ± 9.6 years) were analyzed. The procedures were performed by LenSx Alcon, USA, and Alcon Infiniti Vision System, USA. The following parameters were recorded: laser flare photometry (Kowa FM 700, Japan), anterior chamber (AC) depth, AC volume, AC angle (Pentacam, Oculus Inc., Germany), lens density, pupil diameter, endothelial cell count and pachymetry. The analysis was performed preoperatively, immediately after femtosecond laser procedure and one day postoperatively. Between FLACS and the phaco control group, there was a significant difference in the AC depth (p=0.023, 3.77 mm vs. 4.05 mm) one day postoperatively. The AC angle (p=0.016) showed a significant difference immediately after the femto laser treatment. The central and thinnest pachymetry and endothelial cell count did not show a significant difference between the two study cohorts (p=0.165, p=0.291, p=0.979). The phaco cohort (n=40) demonstrated a non-statistically significant difference in the flare photometry of 15.80 photons/ms one postoperative day compared to the FLACS group 26.62 photons/ms (p=0.322). In this study population, no evidence for an additive damage caused by the use of the femtosecond laser was demonstrated. Furthermore, no increase in the central and thinnest corneal thickness and no increased endothelial cell loss was demonstrated by the laser energy.

Virtual surgery involves the planning and simulation of surgical reconstruction using three-dimensional (3D) modeling based upon individual patient data, augmented by simulation of planned surgical alterations including implantation of devices or grafts. Here we describe a case in which virtual cardiac surgery aided us in determining the optimal conduit size to use for the reconstruction of the right ventricular outflow tract. The patient is a young adolescent male with a history of tetralogy of Fallot with pulmonary atresia, requiring right ventricle-to-pulmonary artery (RV-PA) conduit replacement. Utilizing preoperative magnetic resonance imaging data, virtual surgery was undertaken to construct his heart in 3D and to simulate the implantation of three different sizes of RV-PA conduit (18, 20, and 22 mm). Virtual cardiac surgery allowed us to predict the ability to implant a conduit of a size that would likely remain adequate in the face of continued somatic growth and also allow for the possibility of transcatheter pulmonary valve implantation at some time in the future. Subsequently, the patient underwent uneventful conduit change surgery with implantation of a 22-mm Hancock valved conduit. As predicted, the intrathoracic space was sufficient to accommodate the relatively large conduit size without geometric distortion or sternal compression. Virtual cardiac surgery gives surgeons the ability to simulate the implantation of prostheses of different sizes in relation to the dimensions of a specific patient's own heart and thoracic cavity in 3D prior to surgery. This can be very helpful in predicting optimal conduit size, determining appropriate timing of surgery, and patient education.

Rocuronium is the agent most frequently involved in perioperative anaphylaxis, and sugammadex has also been known to induce anaphylactic reactions. We describe a case of successive anaphylactic episodes that seemed to be induced by clinical doses of rocuronium and sugammadex. The patient was a 19-year-old woman who had a medical history of asthma, but no history of surgery. She had been injured in a fall, and several surgeries were scheduled for multiple bone fractures. At the first surgery under general anesthesia, she developed anaphylaxis 5 min after sugammadex administration. A second general anesthesia for treatment of calcaneal fracture was induced uneventfully without neuromuscular blockade after 10 days. A third general anesthesia was scheduled to reinforce the spinal column 12 days after the first surgery. She developed anaphylaxis 8 min after rocuronium administration. The level of plasma histamine was elevated, but serum tryptase level remained normal. This surgery was canceled and rescheduled without use of a neuromuscular blockade. Skin tests were performed in a later investigation. The patient showed positive results on intradermal tests for sugammadex and rocuronium, supporting a diagnosis of allergic reactions to both drugs. Clinicians must be aware that anaphylactic reactions can be induced by both sugammadex and rocuronium. Copyright © 2016 Elsevier Inc. All rights reserved.

Purpose. To compare the surgical outcomes of staged and combined phacoemulsification with intraocular lens implant (phaco+IOL) and Descemet stripping automated endothelial keratoplasty (DSAEK) in patients with Fuchs' endothelial dystrophy and cataract. Setting. Corneoplastic Unit and Eye Bank, Queen Victoria Hospital, East Grinstead, UK. Methods. Retrospective study of patients who had combined phaco+IOL and DSAEK (group 1) or phaco+IOL followed within 2 months by DSAEK (group 2). Patients who had previous eye surgery or any other ocular comorbidities were excluded. Results. There were 28 eyes in group 1 and 31 in group 2. There were no significant differences in the demographics and corneal tissue characteristics of the two groups. The endothelial disc dislocation and rebubbling rate within 1 week in group 1 was 21.42% and in group 2 was 3.2% (P = 0.04), while the endothelial cell density at 12 months was 1510 ± 433 for group 1 and 1535 ± 482 for group 2 (P = 0.89). The mean 12-month logMAR visual acuity was 0.28 ± 0.24 for group 1 and 0.33 ± 0.15 for group 2 (P = 0.38). Conclusions. Although the combined procedure seems to be associated with a higher complication rate the final outcomes seem to be similar to both methods.

to evaluate the strategy for open heart surgery after renal transplantation performed in a single institution in Japan. we reviewed 6 open heart surgeries after renal transplantation in 5 patients, performed between January 1992 and December 2012. The patients were 3 men and 2 women with a mean age of 60 ± 11 years (range 46-68 years). They had old myocardial infarction and unstable angina, aortic and mitral stenosis, left arterial myxoma, aortic stenosis, and native valve endocarditis followed by prosthetic valve endocarditis. Operative procedures included coronary artery bypass grafting, double-valve replacement, resection of left arterial myxoma, 2 aortic valve replacements, and a double-valve replacement. Renal protection consisted of steroid cover (hydrocortisone 100-500 mg or methylprednisolone 1000 mg) and intravenous immunosuppressant infusion (cyclosporine 30-40 mg day(-1) or tacrolimus 1.0 mg day(-1)). 5 cases were uneventful and good renal graft function was maintained at discharge (serum creatinine 2.1 ± 0.5 mg dL(-1)). There was one operative death after emergency double-valve replacement for methicillin-resistant Staphylococcus aureus-associated prosthetic valve endocarditis. Although the endocarditis improved after valve replacement, the patient died of postoperative pneumonia on postoperative day 45. careful perioperative management can allow successful open heart surgery after renal transplantation. However, severe complications, especially methicillin-resistant Staphylococcus aureus infection, may cause renal graft loss. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Inflammatory reactions are par- tially responsible for postoperative ileus (POI). Serum C-reactive protein (CRP) is an acknowledged marker of inflammation. In this study the CRP response with respect to POI in elective colorectal surgery was exam- ined to define the role of serum CRP as an early predic- tor of POI. Three hundred eighty-three patients who underwent elective colorectal resection were identified for inclusion in this study. We defined early POI as that occurring within 30 days following the surgery. Thirty-five patients with POI were com- pared to a subgroup of 348 patients with an unevent- ful postoperative course, and the correlation between postoperative serum CRP levels and POI in colorectal surgery was investigated. In the univariate analysis, length of operation, surgical blood loss, and serum CRP were factors significantly associated with POI following colorectal surgery; however, these fac- tors lost their significance on multivariate analysis. Our results suggest that an increase in CRP levels alone is not a predictor for POI following surgery for colorectal surgery. Although inflammatory responses are known to contribute to the ileus, ad- ditional study is required to identify risk factors that would be more useful for prediction of POI.

Maxillectomy in childhood not only causes composite primary defects but also secondary malformation of the middle and lower face. In the case presented, we introduced computer-assisted planning and simulation of orthognathic surgery combined with fibular osteomyocutaneous flap reconstruction to correct complex craniofacial deformities. Virtual orthognathic surgery and maxillary reconstruction surgery were undertaken preoperatively. LeFort I osteotomy, with bilateral sagittal split ramus osteotomy and lower border ostectomy, was performed to correct malocclusion and facial asymmetry. Maxillary reconstruction was accomplished using a fibular osteomyocutaneous flap. The patient recovered uneventfully with an adequate aesthetic appearance on 3D computed tomography. Our experience indicates that orthognathic surgery combined with fibular osteomyocutaneous flap reconstruction can used to correct complex facial asymmetry and maxillary defects secondary to maxillectomy. Computer-assisted simulation enables precise execution of the reconstruction. It shortens the free flap ischemia time and reduces the risks associated with microsurgery.

The conventional approach in orthodontic surgery treatment of dentofacial anomalies requires a varied period of pre-surgical orthodontic treatment. This presurgical period is considered to be important for adequate surgical treatment and stable results. This period is usually long bothersome for patients because dental decompensation is required and there is consequent deterioration of aesthetics and function, especially in cases of skeletal Class III occlusion. At Chang Gung Craniofacial Center, a surgery-first approach (SFA), i.e. minimal pre-surgical orthodontics, is one of the treatment choices for Class III patients. In this report, we present a 19-year-old man with mandibular prognathism, an anterior open bite and severe dental crowding treated with SFA. The patient received orthognathic surgery a week after bracing of the teeth. The operation and recovery were uneventful as well as the following orthodontic treatment. The total treatment time was only four months, much shorter than with the conventional approach. The patient benefitted from immediate improvement of the facial profile after surgery, and a much shorter total treatment, and the results were not compromised. We believe in selected cases, SFA is a good and effective treatment alternative.

To describe an unusual series of complications after glaucoma filtering surgeries with their clinical findings and outcome after tailored non-conventional modes of therapy. Eighteen patients who underwent re-interventions (medical or surgical) after glaucoma filtering surgeries during the period at two tertiary centers, excluding those that required conventional modes of treatment (medical control or re-trabeculectomy, simple wound closure for traumatic wound dehiscence, bleb revision or needling, laser iridotomy), were included. Relevant clinical details with intraoperative videos, intraoperative or postoperative problems, and images with course after re-intervention were retrieved from the hospital database. Clinical details which helped in clinching diagnosis and cause for problems and course after intervention with final vision and intraocular pressure were evaluated. Six of 18 eyes required surgical management for an unusual course of events after an uneventful filtering surgery. Bleb morphology and close follow-up of the conjunctiva, in addition to intraocular pressure (IOP) and anterior chamber (AC) configuration, helped diagnose possible aetiology and appropriate tailored management. All patients had good IOP and visual outcome in all except one with macular scar status after retinal detachment surgery. Assessment of the bleb morphology in the postoperative course coupled with monitoring of the conjunctival wound are essential to conventional monitoring of IOP and anterior chamber configuration to arrive at appropriate management for rare unusual events after glaucoma surgery.

To test the hypothesis that major thoracoabdominal surgery induces gene expression changes associated with adverse outcomes. Widely different traumatic injuries evoke surprisingly similar gene expression profiles, but there is limited information on whether the iatrogenic injury caused by major surgery is associated with similar patterns. With informed consent, blood samples were obtained from 50 patients before and after open transhiatal esophagectomy or pancreaticoduodenectomy. Twelve cases with complicated recoveries (death, infection, venous thromboembolism) were matched with 12 cases with uneventful recoveries. Global gene expression was assayed using human microarray chips. A 2-fold change with a corrected P < 0.05 was considered differentially expressed. In these 24 patients, 522 genes were differentially expressed after surgery; 248 (48%) were upregulated (innate immunity and inflammation) and 274 (52%) were downregulated [adaptive immunity (antigen presentation, T-cell function)]. Hierarchical clustering of the profile reliably predicted pre- and postoperative status. The within-patient change was 3.08 ± 0.91-fold. There was no measurable association with age, malignancy, procedure, surgery length, operative blood loss, or transfusion requirements, but was positively associated with postoperative infection (3.81 ± 0.97 vs 2.79 ± 0.73; P = 0.009) and hospital length of stay (r = 0.583, P = 0.003). Venous thromboembolism and mortality each occurred in one patient, thus no associations were possible. Major surgery induces a quantifiable pattern of gene expression change that is associated with adverse outcome. This could reflect early impaired adaptive immunity and suggests potential therapeutic targets to improve postoperative recovery.

Modern day cataract surgery aims at a spectacle free vision which becomes difficult in cases with pre-operative astigmatism more than 1.5 D. Implantation of toric intra-ocular lenses (IOL) after phacoemulsification in such eyes is one of the ways to counteract this problem. Thirty eyes with pre-operative astigmatism between 1.5 D and 4.5 D were implanted with toric IOLs following uneventful phaco-emulsification. The estimation of the axis of implantation of this toric IOL included calculating the surgically induced astigmatism (SIA) of the surgeon. Post-operatively, 20 (66.67%) patients had a visual acuity 6/9 or better and 17 (57%) had a visual acuity of 6/6 at 12 weeks. The mean postoperative uncorrected visual acuity (UCVA) was 0.12 ± 0.15 at 12 weeks. The difference between means of preoperative best corrected visual acuity (BCVA) LogMAR and postoperative UCVA at 12 wk LogMAR was found to be statistically significant at p  = 0.001. Mean (SD) scores of pre-op astigmatism of study group was -2.20 (0.67) and residual astigmatism was -0.32 (0.44). The difference between means of pre-op astigmatism and residual astigmatism in the study group was significant at p  = 0.001 with 95% CI -2.22 to -1.50. This significant difference was because of the toric IOL implantation.

Pre-operative assessment of patients undergoing endoscopic, transnasal, transsphenoidal pituitary surgery.

To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

Background: Cataract is one of the most common surgical procedures in the elderly. In most cases, the elderly have cardiac ischemia or chronic coronary diseases, which would lead to more ischemic events during general anesthesia. Therefore, surgeons and anesthetists prefer regional aesthesia to the general one owing to its more advantages and less complications. Objectives: Therefore, this study aimed to compare topical method and retrobulbar block for pain intensity, patient’s satisfaction, hemodynamic changes and intra and postoperative complications. Patients and Methods: In a single-blinded clinical trial, 114 patients scheduled for cataract surgery, aged 50 to 90 years with ASA physical status of I-III, were randomly assigned to two groups under monitored anesthesia care as topical anesthesia and retrobulbar block. After the injection of intravenous sedation, which was the combination of midazolam 0.5-1 mg with fentanyl 0.5-1 µ/kg, patients received retro bulbar block or topical anesthesia. During the operation, heart rate, systolic and diastolic blood pressure, mean arterial blood pressure and arterial saturation of O2were measured every five minutes. In addition, pain (VAS) and satisfaction (ISAS) scores were recorded every 15 minutes, then at recovery and one hour after the ending of operation in the ward. Findings were statistically analyzed using SPSS 16. Results: In this study, no significant association was found between age, gender, education and physical condition of patients in both topical and retro bulbar block groups. Comparison of pain based on VAS, satisfaction based on ISAS score and MAP in the studied periods had no significant differences between the two groups of patients undergoing cataract surgery. However, significant differences were found between the two groups (P = 0.045, 0.02, 0.042 and P < 0.05) regarding heart rate, systolic and diastolic blood pressure and arterial oxygen saturation percentage after 20-30 minutes of the

Myofibrosarcoma is a rare malignant mesenchymal tumor composed predominantly of differentiated myofibroblasts. These tumors occur in both children and adults alike and are most commonly located on the head and neck. Recurrences rates range from 44% to 75%, and metastatic disease has been reported in up to 44% of cases. The objective was to present a case of a myofibrosarcoma treated with Mohs micrographic surgery and discuss the use of ultrastructural evaluation in the diagnosis of this rare tumor. A 31-year-old African American woman who presented to the Emory University Dermatologic Surgery Clinic with a 4-month history of a 2.5 x 2.5-cm indurated firm painful right upper lateral thigh nodule. A prior biopsy revealed a proliferation of somewhat bland spindled cells with large zones of necrosis with prominent mitotic figures, changes compatible with a cellular dermatofibroma. Because the lesion exhibited clinically suspicious characteristics such as rapid growth and deep infiltration, the patient was subsequently referred to Emory for further evaluation. There was no evidence of lymphadenopathy and a chest X-ray was unremarkable. A two-staged (five and four sections, respectively) uneventful Mohs micrographic surgery procedure was performed resulting in a defect measuring 3.5 x 3.5 x 1.0 cm. Primary closure was achieved with no complication, and the final scar measured 10 cm. Because of the suspicious clinical behavior of this tumor debulking specimen was sent for permanent section. Histopathologic interpretation of these sections was consistent with a fibrosarcoma with myofibroblastic differentiation. No clinical recurrence noted after 14-month follow-up. Mohs micrographic surgery is a technique that has been shown to provide superior cure rates in the treatment of many mesenchymal tumors. Here, we report the first case of myofibrosarcoma treated with Mohs micrographic surgery. Myofibrosarcoma is a rare but aggressive tumor that can be difficult to distinguish

We report the case of a patient with pyogenic spondylodiscitis after transoral surgery for oropharyngeal cancer. The patient was a 66-year-old man with a history of hepatic cell carcinoma, alcoholic cirrhosis, and chronic pancreatitis. The tumor was resected via a transoral approach with concurrent bilateral elective neck dissections. Although the initial postoperative course was uneventful, the patient experienced severe cervical pain because of which he revisited the hospital. The patient was diagnosed with pyogenic spondylodiscitis, according to the results of magnetic resonance imaging. Continuous treatment with parenteral antibiotics and a cervical brace was required for 2 months before all his symptoms and signs diminished. To the best of our knowledge, this is the first reported case of pyogenic spondylodiscitis as a complication of transoral resection for head and neck cancer. Copyright © 2012 Elsevier Ireland Ltd.

Purpose. To compare the surgical outcomes of staged and combined phacoemulsification with intraocular lens implant (phaco+IOL) and Descemet stripping automated endothelial keratoplasty (DSAEK) in patients with Fuchs' endothelial dystrophy and cataract. Setting. Corneoplastic Unit and Eye Bank, Queen Victoria Hospital, East Grinstead, UK. Methods. Retrospective study of patients who had combined phaco+IOL and DSAEK (group 1) or phaco+IOL followed within 2 months by DSAEK (group 2). Patients who had previous eye surgery or any other ocular comorbidities were excluded. Results. There were 28 eyes in group 1 and 31 in group 2. There were no significant differences in the demographics and corneal tissue characteristics of the two groups. The endothelial disc dislocation and rebubbling rate within 1 week in group 1 was 21.42% and in group 2 was 3.2% (P = 0.04), while the endothelial cell density at 12 months was 1510 ± 433 for group 1 and 1535 ± 482 for group 2 (P = 0.89). The mean 12-month logMAR visual acuity was 0.28 ± 0.24 for group 1 and 0.33 ± 0.15 for group 2 (P = 0.38). Conclusions. Although the combined procedure seems to be associated with a higher complication rate the final outcomes seem to be similar to both methods. PMID:26064669

Purpose This paper compares and evaluates the corneal morphological changes occurring after cataract surgery through a 2.2 mm corneal incision. We use two platforms for comparison and evaluation, transversal and torsional phacoemulsification. Patients and methods This study includes 139 consecutive cataractous eyes (nuclear color 2–4, according to the Lens Opacities Classification System III [LOCSIII]) of 82 patients undergoing cataract surgery through a 2.2 mm corneal incision. Two different phacoemulsification platforms were used and assigned randomly: we used the WhiteStar Signature® system with the Ellips™ FX transversal continuous ultrasound (US) mode for group I (mean age: 65.33 ± 6.97 years), and we used the Infiniti® system with the OZil® Intelligent Phaco (IP) torsional US mode for group II (mean age: 64.02 ± 7.55 years). The corneal endothelium and pachymetry were evaluated preoperatively and at 1 month postoperatively. Incision size changes were also evaluated. Results All surgeries were uneventful. Before intraocular lens implantation, the mean incision size was 2.24 ± 0.06 mm in both groups (P = 0.75). In terms of corneal endothelial cell density, neither preoperative (I vs II: 2304.1 ± 122.5 cell/mm2 vs 2315.6 ± 83.1 cell/mm2, P = 0.80) nor postoperative (I vs II: 2264.1 ± 124.3 cell/mm2 vs 2270.3 ± 89.9 cell/mm2, P = 0.98) differences between the groups were statistically significant. The mean endothelial cell density loss was 1.7% ± 1.6% and 2.0% ± 1.4% in groups I and II, respectively. Furthermore, no significant differences between groups I and II were found preoperatively (P = 0.40) and postoperatively (P = 0.68) in central pachymetry. With surgery, the mean increase in central pachymetry was 28.1 ± 23.6 μm and 24.0 ± 24.0 μm in groups I and II, respectively (P = 0.1). Conclusion Ellips™ FX transversal and OZil® IP torsional phacoemulsification modes are safe for performing cataract surgery, inducing minimal corneal

The successful development of cataract operation and IOL implantation in the last decade has resulted in progressive shortening of the incision length as well as in developing safer and simpler anesthetic techniques. The purpose of the present study was to evaluate whether cataract surgery with scleral incision is possible using only topical sponge anesthesia with oxybuprocaine 0.4%. This method was compared with retrobulbar injection. 150 patients (3 groups each consisting 50 eyes) underwent phaco with scleral incision. 1st group: oxybuprocaine sponge anesthesia. 2nd group: oxybuprocaine sponge anesthesia combined with mild systemic analgesia (tramadol p.o.). 3rd group: retrobulbar injection (prilocaine/etidocaine mixture). All patients received medazolam premedication (Dormicum, 3/10 of 1 cc). Pain and discomfort during and after operation were investigated and statistically analyzed. Neither in group 1, 2 or 3 an additional subconjunctival injection was necessary. Pain or discomfort during operation was felt in 14 percent of the patients anesthetized with the oxybuprocaine sponge but only in 6 percent of the patients additionally premedicated with tramadol (2nd group). Also 6 percent of the patients after retrobulbar injection felt pain during operation. Postoperatively no significant differences between group 1 and 2 were obtained: 6 percent felt pain, 30 percent had a short term foreign body sensation. After retrobulbar injection (group 3) only 10 percent felt postoperative pain or discomfort. Topically applied oxybuprocaine provides sufficient anesthesia during cataract surgery with scleral incision. A combination with mild systemic analgesia (tramadol) helps to minimize pain and discomfort. Retrobulbur injection yielded only in the postoperative period significantly better analgesia. In the operating room full cooperation of the patient is required. Therefore we recommend not to use sponge anesthesia in cases when communication between surgeon and patient is

To evaluate the effectiveness of a hydrogel sealant versus a suture in preventing fluid egress after wound leakage in cataract surgery. Twenty-four ophthalmic clinical practices in the United States. Prospective randomized parallel-arm controlled multicenter subject-masked study. Healthy patients having uneventful clear corneal incision (CCI) cataract surgery were eligible for the study. Spontaneous and provoked fluid egress from wounds was evaluated at the time of surgery using a calibrated force gauge. Eyes with leakage were randomized to receive a hydrogel sealant (Resure) or a nylon suture at the main incision site. Incision leakage was reevaluated 1, 3, 7, and 28 days postoperatively. Of 500 eyes, 488 had leakage at the time of cataract surgery. The leak was spontaneous in 244 cases (48.8%), and 488 (97.6%) of all incisions leaked with 1.0 ounce or less of applied force. After randomization, 12 (4.1%) of 295 eyes in the sealant group and 60 (34.1%) of 176 eyes in the suture group had wound leakage with provocation (P<.0001). The overall incidence of adverse ocular events was statistically significantly lower in the sealant group than in the suture group (P<.05). In this study, 97.6% of CCIs leaked after cataract surgery. The hydrogel sealant was safe and effective and better than a suture for the intraoperative management of CCIs with leakage as seen on Seidel testing and for the prevention of postoperative fluid egress.

Maximal safe resection is the goal of correct surgical treatment of parasagittal meningiomas, and it is intimately related to the venous anatomy both near and directly involved by the tumor. Indocyanine green videoangiography (ICGV) has already been advocated as an intra-operative resourceful technique in brain tumor surgery for the identification of vessels. The aim of this study was to investigate the role of ICGV in surgery of parasagittal meningiomas occluding the superior sagittal sinus (SSS). In this study, we prospectively analyzed clinical, radiological and intra-operative findings of patients affected by parasagittal meningioma occluding the SSS, who underwent ICGV assisted-surgery. Radiological diagnosis of complete SSS occlusion was pre-operatively established in all cases. ICGV was performed before dural opening, before and during tumor resection, at the end of the procedure. Five patients were included in our study. In all cases, ICGV guided dural opening, tumor resection, and venous management. The venous collateral pathway was easily identified and preserved in all cases. Radical resection was achieved in four cases. Surgery was uneventful in all cases. Despite the small number of patients, our study shows that ICG videoangiography could play a crucial role in guiding surgery of parasagittal meningioma occluding the SSS. Further studies are needed to define the role of this technique on functional and oncological outcome of these patients.

Renal cell carcinoma in a transplant kidney is a rare condition. Nephron Sparing Surgery (NSS) is the treatment of choice. One of the main technical challenges is obtaining adequate vascular control. We present a rare case of large centrally located hillar tumor in a kidney 18 years after transplantation treated with NSS. Vascular control was achieved by using a novel approach. Post-operative course was uneventful with minimal decrease in renal function. We believe that this unique choice of treatment can be used in cases of NSS where the access to the renal pedicle is limited.

To evaluate the validity and responsiveness of the self-administered Quality of Well-Being Scale (QWB-SA) and the 14-item Visual Function Index (VF-14) to assess patients having cataract surgery. Large Southern California health maintenance organization. This study comprised 233 adults who had uneventful small-incision (< 3.0 mm) phacoemulsification cataract extraction under local anesthesia. Patients were assessed before surgery as well as 4 to 6 weeks and 4 months after surgery using the QWB-SA and the VF-14. Postoperatively, patients reported significant improvements on QWB-SA (P < .005) and VF-14 (P < .001) measures. Those grouped by visual acuity in the operated eye and unoperated eye and first-eye surgery or second-eye surgery had significant changes in VF-14 results (P < .001). Improvements on the QWB-SA were significant except when the preoperative visual acuity was better than 20/40 in the operated eye or 20/50 in the unoperated eye and when patients had first-eye surgery. The vision-specific VF-14 was more sensitive to improvements after surgery than the more general QWB-SA. Both demonstrated a greater magnitude of change with lower baseline scores and correlated significantly with self-reported satisfaction and trouble with vision. Both the utility-based generic QWB-SA and disease-specific VF-14 profile were responsive to changes in quality of life after cataract surgery. The VF-14 was more sensitive to change but cannot be used for comparison across disease states or for policy analysis. The QWB-SA can be used to estimate the cost/utility of cataract surgery.

Achondroplasia is the most common form among the different types of osteochondrodysplasia that cause dwarfism. Dwarves develop obesity quite frequently and surgical treatment has shown greater efficacy, both for effective weight loss and long term maintenance. The objective of this report was to present the case of bariatric surgery with Y-en-Roux gastric bypass in an achondroplastic dwarf with morbid obesity. The different difficulties in the anesthetic management of this patient and the way they were dealt with were discussed in order to decrease intraoperative morbidity and mortality. This is a 29 years old female dwarf with achondroplasia and morbid obesity since childhood. She was 123 cm tall and weighed 144 kg at the time of admission to the Bariatric Surgery service. With a body mass index (BMI) of 95.18 kg.m2, she had several associated diseases especially of the respiratory system and osteoarticular system. After a long follow-up with diet, exercises, and psychological support, her clinical condition improved and she was referred for surgery: Y-en-Roux gastroplasty using the technique of Capella-Fobi. Intubation of the awake patient under direct laryngoscopy was difficult and a bronchofibroscope had to be used. Surgery was uneventful and the patient was maintained under total intravenous anesthesia with continuous infusion of remifentanil and propofol. She was extubated at the end of the surgery still in the operating room. The simultaneous comorbidities of achondroplasia and morbid obesity can hinder the anesthetic management, especially regarding the airways. A thorough pre-anesthetic evaluation is necessary to anticipate the conducts and minimize risks, therefore optimizing the evolution of anesthesia.

We present a case of allergic reaction to patent blue in a patient who underwent excision of sentinel lymph node associated with segmental breast resection. About 20minutes after the dye injection, the patient developed hypotension (BP=70×30mmHg) associated with increased heart frequency. The patient was treated successfully with decreased inspired fraction of inhaled anesthetic and fluid replacement. At the end of the procedure, she presented with bluish urticarial - like plaques on the head, neck, upper limbs, and trunk; hydrocortisone was then used. The patient recovered uneventfully and was discharged from the PACU two hours after the end of surgery without skin changes, and was discharged from hospital on the morning after surgery. The incidence of allergic reactions with the use of patent blue is far superior to the hypersensitivity reactions seen with anesthetic and adjuvant drugs. Therefore, the anesthesiologist must be aware of cardiovascular instability associated with skin changes during the use of patent blue, for early diagnosis and appropriate treatment of this hypersensitivity reaction to this dye.

We present a case of allergic reaction to patent blue in a patient who underwent excision of sentinel lymph node associated with segmental breast resection. About 20min after the dye injection, the patient developed hypotension (BP=70×30mmHg) associated with increased heart frequency. The patient was treated successfully with decreased inspired fraction of inhaled anesthetic and fluid replacement. At the end of the procedure, she presented with bluish urticarial-like plaques on the head, neck, upper limbs, and trunk; hydrocortisone was then used. The patient recovered uneventfully and was discharged from the PACU 2h after the end of surgery without skin changes, and was discharged from hospital on the morning after surgery. The incidence of allergic reactions with the use of patent blue is far superior to the hypersensitivity reactions seen with anesthetic and adjuvant drugs. Therefore, the anesthesiologist must be aware of cardiovascular instability associated with skin changes during the use of patent blue, for early diagnosis and appropriate treatment of this hypersensitivity reaction to this dye.

Lung transplantation is a limited by donor pool shortage. Despite the efforts to extend the graft acceptability with recurrent donor criteria reformulations, previous cardiothoracic surgery is still considered a contraindication. A donor who underwent cardiac surgery could potentially provide an ideal lung but high intraoperative risks and intrinsic technical challenges are expected during the graft harvesting. The purpose of this study is to present our dedicated protocol and four clinical cases of successful lung procurements from donors who had a previous major cardiac surgery. One donor had ascending aortic root (AAR) substitution, another had mitral valve substitution, and two had coronary artery bypass surgery. The others' eligibility criteria for organ allocation, such as ABO compatibility, PaO 2 /FiO 2 ratio, absence of aspiration, or sepsis were respected. In one of the cases with previous coronary bypass grafting, the donor had a veno-arterial extracorporeal membrane oxygenation support. Consequently, the grafts required an ex vivo lung perfusion evaluation. We report the technical details of procurement and postoperative courses of recipients. All procurements were uneventful, without lung damage or waste of abdominal organs related to catastrophic intraoperative events. All recipients had a successful clinical outcome. We believe that successful transplantation is achievable even in a complicated setting, such as cases involving donors with previous cardiac surgery frequently are. Facing lung donor shortage, we strongly support any effort to avoid the loss of possible acceptable lungs. In particular, previous major cardiac surgery does not strictly imply a poor quality of lungs as well as unsustainable graft procurement. Copyright © 2017 Elsevier Inc. All rights reserved.

Elephantiasis nostras is a rare complication in advanced lipo-lymphedema. While lipedema can be treated by liposuction and lymphedema by decongestive lymphatic therapy, elephantiasis nostras may need debulking surgery. We present 2 cases of advanced lipo-lymphedema complicated by elephantiasis nostras. After tumescent microcannular laser-assisted liposuction both patients underwent a debulking surgery with a modification of Auchincloss-Kim's technique. Histologic examination of the tissue specimen was performed. The surgical treatment was well tolerated and primary healing was uneventful. After primary wound healing and ambulation of the patients, a delayed ulceration with lymphorrhea developed. It was treated by surgical necrectomy and vacuum-assisted closure leading to complete healing. Mobility of the leg was much improved. Histologic examination revealed massive ectatic lymphatic vessels nonreactive for podoplanin. Debulking surgery can be an adjuvant technique for elephantiasis nostras in advanced lipo-lymphedema. Although delayed postoperative wound healing problems were observed, necrectomy and vacuum-assisted closure achieved a complete healing. Histologic data suggest that the ectatic lymphatic vessels in these patients resemble finding in podoplanin knockout mice. The findings would explain the limitations of decongestive lymphatic therapy and tumescent liposuction in such patients and their predisposition to relapsing erysipelas.

We aimed to evaluate the efficacy of topical ketorolac 0.5 % solution and oral acetazolamide 250 mg/day delivery during the first month after uneventful phacoemulsification surgery by measuring the macular thickness using optical coherence tomography. Our nonmasked randomized prospective study comprised 87 eyes of 80 patients. Complete follow-up was achieved on 84 eyes of 77 eligible patients. Postoperatively, the patients were divided into three groups. One group received ketorolac 0.5 %, the other group received acetazolamide 250 mg/day, and the control group was given no agent. Macular thickness and volume were measured at 1 week and 1 month after surgery by optical coherence tomography. Foveal thickness, parafoveal thickness, and perifoveal thickness were determined to be significantly elevated at postoperative 1 week and 1 month in the control group. Foveal, perifoveal, and parafoveal volumes were also significantly high at postoperative week 1 and month 1 in the control group. There was no significant difference between the ketorolac and acetazolamide groups. The correlation analysis between best-corrected visual acuity, and volume and thickness revealed a negative correlation in the acetazolamide group. Use of acetazolamide after cataract surgery is as effective as ketorolac on macular thickness and volume.

A 56-year-old woman had conductive keratoplasty (CK) for residual hyperopia and astigmatism. Three years before the procedure, the patient had arcuate keratotomy, followed by laser in situ keratomileusis 2 years later for high astigmatism correction in both eyes. During CK, a corneal perforation occurred in the right eye; during the postoperative examination, an iris perforation and anterior subcapsule opacification were seen beneath the perforation site. The perforation was managed with a bandage contact lens and an antibiotic-steroid ointment; it had a negative Seidel sign by the third day. The surgery in the left eye was uneventful. Three months after the procedure, the uncorrected visual acuity was 20/32 and the best corrected visual acuity 20/20 in both eyes with a significant improvement in corneal topography. Care must be taken to prevent CK-treated spots from coinciding with areas in the corneal stroma that might have been altered by previous refractive procedures.

To describe the intraoperative complications and the learning curve of microincision cataract surgery assisted by femtosecond laser (FLACS) with bimanual technique performed by an experienced surgeon. It is a prospective, observational, comparative case series. A total of 120 eyes which underwent bimanual FLACS by the same experienced surgeon during his first experience were included in the study; we considered the first 60 cases as Group A and the second 60 cases as Group B. In both groups, only nuclear sclerosis of grade 2 or 3 was included; an intraocular lens was implanted through a 1.4-mm incision. Best-corrected visual acuity (BCVA), surgically induced astigmatism (SIA), central corneal thickness and endothelial cell loss (ECL) were evaluated before and at 1 and 3 months after surgery. Intraoperative parameters, and intra- and post-operative complications were recorded. In Group A, we had femtosecond laser-related minor complications in 11 cases (18.3%) and post-operative complications in 2 cases (3.3%); in Group B, we recorded 2 cases (3.3%) of femtosecond laser-related minor complications with no post-operative complications. Mean effective phaco time (EPT) was 5.32 ± 3.68 s in Group A and 4.34 ± 2.39 s in Group B with a significant difference (p = 0.046). We recorded a significant mean BCVA improvement at 3 months in both groups (p < 0.05) and no significant SIA nor corneal pachymetry changes in the two groups during the follow-up (p > 0.05). Finally, we found significant ECL in both groups with a significant difference between the two groups (p = 0.042). FLACS with bimanual technique and low-energy LDV Z8 is associated with a necessary initial learning curve. After the first adjustments in the surgical technique, this technology seems to be safe and effective with rapid visual recovery and it helps surgeons to standardize the crucial steps of cataract surgery.

Background/aim Himalaya Eye Hospital (HEH), established in 1993, is rendering eye care services in the Gandaki and Dhaulagiri zones. The hospital has extensive community outreach activities along with services for outpatients, emergencies, and subspecialties such as vitreoretinal, paediatric, and low vision. The operation theatre is well equipped to match the surgical needs including phaco surgery for cataract. The hospital has performed more than 14 000 cataract surgeries and 250 000 treatment services during this period. The aim of this study was to estimate the prevalence of blindness, visual impairment, and cataract surgical coverage among the older adult population of three districts of Gandaki Zone, where 80% of the hospital's service recipients reside. Methods People aged 45 years and older were enrolled in the study using a stratified cluster design. Subjects in 25 randomly selected clusters from the listed 806 were recruited through door to door visits. Each recruited subject had visual acuity (VA) and clinical examination conducted by an ophthalmologist. The survey was preceded by pre‐pilot and pilot studies to refine the operational method. To assess quality assurance the interobserver variation in VA measurement was also carried out in five different clusters. Results Out of 5863 selected subjects 85.3% were examined. Blindness defined as presenting VA <6/60 in both eyes was found in 2.6% (95% confidence interval (CI): 2.2 to 3.9), whereas 16.8% individuals examined had vision <6/19 in one or both eyes. Cataract was the principal cause of blindness in 60.5%, and refractive error was the dominant cause of vision impairment (<6/19) 83.3%. Cataract surgical coverage was 59.5% among the cataract blind and associated with younger age, literacy, and male sex. Conclusion The finding suggests a positive impact of the HEH programme on the prevalence of blindness and cataract surgical services in the survey area. Strategies to further improve access and

Bypass surgery to treat symptomatic fusiform dilation of the internal carotid artery following craniopharyngioma resection: report of 2 cases.

Fusiform dilation of the internal carotid artery (FDICA) is an infrequent vascular complication following resection of suprasellar lesions in the pediatric population, and its course appears to be benign without apparent clinical symptoms. However, data correlating symptomatic FDICA with bypass surgery are scarce. The authors here report 2 symptomatic cases that were treated using internal maxillary artery bypass more than 5 years after total removal of a craniopharyngioma at an outside institution. Both cases of FDICA were resected to relieve the mass effect and to expose the craniopharyngioma. The postoperative course was uneventful, and radiological imaging revealed graft conduit patency. To the authors' knowledge, this is the first reported use of extracranial to intracranial bypass to treat FDICA following removal of a suprasellar lesion. Their findings suggest that bypass surgery is a useful therapeutic approach for symptomatic cases of FDICA and total removal of recurrent craniopharyngioma. Moreover, the indications for surgical intervention and treatment modalities are discussed in the context of previous relevant cases.

Traditional surgery presents some disadvantages, such as the necessity for general anesthesia, hemorrhage, recurrence of pathology, and the possible onset of dyspareunia due to an excessive scarring. CO2 laser surgery might resolve these problems and might be employed in a wider range of clinical indications than usual. We examined the results of CO2 laser surgery in patients affected by benign pathologies and congenital malformations of the female lower genital tract. In this observational study, we enrolled 49 women who underwent CO2 laser surgery for the following indications: Bartholin's gland cyst, imperforate hymen, vaginal septum, Nabothian cyst, and vaginal polyps. Feasibility, cost-effectiveness, complication rate, recurrence rate, short- and long-term outcomes were assessed. All procedures were carried out in a short operative time, without any intraoperative complications. Only 1 (2.0%) out of 49 patients required a hemostatic suture for bleeding. Postoperative period was uneventful in all patients, except 6 (12.2%) out of 49 patients who reported pain one day after surgery, successfully treated with paracetamol. Healing was rapid and excellent in all cases; no wound infection, scarring or stenosis were noticed. Preoperative symptoms reduced or disappeared in all cases. No recurrence was observed and no re-intervention was needed. CO2 laser surgery provides several advantages over traditional surgery, as its systematic use in treating pre-invasive, benign, and congenital pathologies of the female lower genital tract reduces patient discomfort, improves short- and long-term outcomes, and optimizes cost-effectiveness.

Thoracic spinal anesthesia is safe for patients undergoing abdominal cancer surgery.

2014-01-01

A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can't tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than

We herein report the case of a patient demonstrating a lung abscess with acute empyema which improved after performing pnemumonotomy and lung abscess drainage. A 60-year-old male was referred to our hospital to receive treatment for a lung abscess with acute empyema. At surgery, the lung parenchyma was slightly torn with pus leakage. After drainage of lung abscess by enlarging the injured part, curettage in the thoracic cavity and decortication were performed. The postoperative course was uneventful. Direct drainage of an abscess into the thoracic cavity is thought to be a choice for the treatment of lung abscesses.

Purpose The aim of the study was to compare the efficacy of parecoxib for postoperative analgesia after endoscopic turbinate and sinus surgery with the prodrug of acetaminophen, proparacetamol. Materials and Methods Fifty American Society of Anesthesiology (ASA) physical status I-II patients, receiving functional endoscopic sinus surgery (FESS) and endoscopic turbinectomy, were investigated in a prospective, randomized, double-blind manner. After local infiltration with 1% mepivacaine, patients were randomly allocated to receive intravenous (IV) administration of either 40 mg of parecoxib (n = 25) or 2 g of proparacetamol (n = 25) 15 min before discontinuation of total IV anaesthesia with propofol and remifentanil. A blinded observer recorded the incidence and severity of pain at admission to the post anaesthesia care unit (PACU) at 10, 20, and 30 min after PACU admission, and every 1 h thereafter for the first 6 postoperative h. Results The area under the curve of VAS (AUCVAS) calculated during the study period was 669 (28 - 1901) cm·min in the proparacetamol group and 635 (26 - 1413) cm·min in the parecoxib group (p = 0.34). Rescue morphine analgesia was required by 14 patients (56%) in the proparacetamol group and 12 patients (48%) in the parecoxib (p ≥ 0.05), while mean morphine consumption was 5 - 3.5 mg and 5 - 2.0 mg in the proparacetamol groups and parecoxib, respectively (p ≥ 0.05). No differences in the incidence of side effects were recorded between the 2 groups. Patient satisfaction was similarly high in both groups, and all patients were uneventfully discharged 24 h after surgery. Conclusion In patients undergoing endoscopic nasal surgery, prior infiltration with local anaesthetics, parecoxib administered before discontinuing general anaesthetic, is not superior to proparacetamol in treating early postoperative pain.

To conduct a systematic review and quantitative Meta-analysis of the efficacy and safety of combined surgery for the eyes with coexisting cataract and open angle glaucoma. We performed a systematic search of the related literature in the Cochrane Library, PubMed, EMBASE, Web of Science databases, CNKI, CBM and Wan Fang databases, with no limitations on language or publication date. The primary efficacy estimate was identified by weighted mean difference of the percentage of intraocular pressure reduction (IOPR%) from baseline to end-point, the percentage of number of glaucoma medications reduction from pre- to post-operation, and the secondary efficacy evaluations were performed by odds ratio (OR) and 95% confidence interval (CI) for complete and qualified success rate. Besides, ORs were applied to assess the tolerability of adverse incidents. Meta-analyses of fixed or random effect models were performed using RevMan software 5.2 to gather the consequences. Heterogeneity was evaluated by Chi 2 test and the I 2 measure. Ten studies enrolling 3108 patients were included. The combined consequences indicated that both glaucoma and combined cataract and glaucoma surgery significantly decreased IOP. For deep sclerectomy vs deep sclerectomy plus phacoemulsification and canaloplasty vs phaco-canaloplasty, the differences in IOPR% were not all statistically significant while trabeculotomy was detected to gain a quantitatively greater IOPR% compared with trabeculotomy plus phacoemulsification. Furthermore, there was no statistical significance in the complete and qualified success rate, and the rates of adverse incidents for trabeculotomy vs trabeculotomy plus phacoemulsification. Compared with trabeculotomy plus phacoemulsification, trabeculectomy alone is more effective in lowering IOP and the number of glaucoma medications, while the two surgeries can not demonstrate statistical differences in the complete success rate, qualified success rate, or incidence of adverse

To analyze the epidemiologic features of ectasia after excimer laser corneal refractive surgery, to identify risk factors for its development, and to devise a screening strategy to minimize its occurrence. Retrospective comparative and case-control study. All cases of ectasia after excimer laser corneal refractive surgery published in the English language with adequate information available through December 2005, unpublished cases seeking treatment at the authors' institution from 1998 through 2005, and a contemporaneous control group who underwent uneventful LASIK and experienced a normal postoperative course. Evaluation of preoperative characteristics, including patient age, gender, spherical equivalent refraction, pachymetry, and topographic patterns; perioperative characteristics, including type of surgery performed, flap thickness, ablation depth, and residual stromal bed (RSB) thickness; and postoperative characteristics including time to onset of ectasia. Development of postoperative corneal ectasia. There were 171 ectasia cases, including 158 published cases and 13 unpublished cases evaluated at the authors' institution. Ectasia occurred after LASIK in 164 cases (95.9%) and after photorefractive keratectomy (PRK) in 7 cases (4.1%). Compared with controls, more ectasia cases had abnormal preoperative topographies (35.7% vs. 0%; P<1.0x10(-15)), were significantly younger (34.4 vs. 40.0 years; P<1.0x10(-7)), were more myopic (-8.53 vs. -5.09 diopters; P<1.0x10(-7)), had thinner corneas before surgery (521.0 vs. 546.5 microm; P<1.0x10(-7)), and had less RSB thickness (256.3 vs. 317.3 microm; P<1.0x10(-10)). Based on subgroup logistic regression analysis, abnormal topography was the most significant factor that discriminated cases from controls, followed by RSB thickness, age, and preoperative corneal thickness, in that order. A risk factor stratification scale was created, taking all recognized risk factors into account in a weighted fashion. This model had a

No data exist in the English-language literature about patients with Barlow disease associated to Steinert syndrome and little is known about the employment of hypothermic cardiopulmonary bypass (CPB) and hyperkalemic cardioplegia in these patients. We present our experience with six patients affected by myxomatous degeneration associated to Steinert disease undergoing complex mitral valve repair. In all patients we employed mild hypothermic CPB (31 degrees C) and myocardial protection was achieved, in the entire cohort, by the use of blood hyperkalemic cold cardioplegia. The postoperative course was uneventful in all patients and neither shivering nor generalized muscle contraction were observed. Furthermore, all patients have remained well on an outpatient basis. Hypothermic CPB and hyperkalemic cardioplegia can be safely employed in patients with Steinert syndrome requiring complex cardiac surgery. Further large studies are necessary to confirm our findings.

Gallbladder polyps are tumors or tumor-like protrusions of the gallbladder. They are rarely seen in the pediatric age. Most important issue about these mostly incidental lesions is the risk of malignant transformation. Size more than 10 mm is the classicalcutoff for determining this risk, but it is rarely valid in children. Ultrasonography is the method of choice for follow-up, but it rarely demonstrates change of size or malignant transformation. Hereby, we report 6 cases of childhood gallbladder polyps, none of which had a genetic risk factor. Follow-up was uneventful in 4 of them. Two patients had undergone surgery, but none of the lesions were neoplastic. In the follow-up, a single experienced radiologist should handle the patient, in order to prevent inter-observer variation. The cut-off size for deciding surgery should be 10 mm for those cases with genetic background creating malignancy risk (metachromatic leukodystrophy, pancreaticobiliary duct abnormalities, achondroplasia, Peutz-Jeghers syndrome) or with accompanying cholelithiasis, and 15 mm for those without any risk factors to prevent any unnecessary operations.

To gauge the differences in ophthalmology residency training, academic, clinical and surgical, in the last three decades of the 20 th century and the first decade of the 21 st century. A survey was conducted by the Academic and Research Committee of the All India Ophthalmological Society, in 2014-2016, using a prevalidated questionnaire, which was circulated to ophthalmologists to gauge the practicality of the teaching protocols of clinical and surgical skills during postgraduate residency program. Of the 1005 respondents, 320 ophthalmologists who completed residency between 1967 and 2002 (20 th century trained) and 531 who completed a residency in 2003-2012 (21 st century trained) fulfilled the inclusion criteria. The average age was 49.2 years (standard deviation [SD] 4) and 32.6 years (SD 4), respectively. Twenty-first century trained ophthalmologists rated their training significantly better than the 20 th century trained ophthalmologists for slit lamp examination (P = 0.001), indirect ophthalmoscopy, gonioscopy, automated perimetry, optical coherence tomography, and fundus photography (all having P < 0.001), while the 20 th century trained rated their teaching of refraction, synoptophore, diplopia charting better (all P < 0.001). The range of grading was 0-10 in all categories.

To evaluate the safety and efficacy of gas-forced infusion (air pump) in uncomplicated coaxial phacoemulsification. Dr. Agarwal's Eye Hospital, Chennai, India. Comparative case series. Specular microscopy and optical coherence tomography were used to analyze the endothelium, central macular thickness (CMT), and peripapillary retinal nerve fiber layer (RNFL) thickness before and approximately 1, 7, 30, and 90 days after coaxial phacoemulsification with (infusion group) or without (control group) gas-forced infusion. Surgical time, surge, phaco energy, irrigation fluid volume, surgical ease, complications, and visual gain in the 2 groups were compared. The mean endothelial cell loss was lower in the infusion group than in the control group (6.98% ± 8.46% [SD] versus 10.54% ± 11.24%; P = .045) and the irrigation/aspiration time significantly shorter (54 ± 39 seconds versus 105 ± 84 seconds; P = .0001). The surgery was rated as easier with gas-forced infusion (scale 1 to 10: mean 8.3 ± 2.1 versus 6.6 ± 1.6; P = .00002). However, the amount of irrigating fluid volume was higher in the infusion group (117 ± 37 mL versus 94 ± 41 mL; P = .003). No surge occurred in the infusion group; it occurred a mean of 3.00 ± 4.16 times in the control group (P<.0001). The rate of visual gain, CMT, peripapillary RNFL thickness, phaco time, and amount of phaco energy were comparable in the 2 groups. Gas-forced infusion was safe and effective in controlling surge and increased the safety, ease, and speed of coaxial phacoemulsification. Copyright © 2010 ASCRS and ESCRS. Published by Elsevier Inc.

To investigate the effects of intracameral carbachol in phacoemulsification surgery on central macular thickness (CMT), total macular volume (TMV) and retinal vessel caliber (RVC). In this prospective consecutive case series, 82 patients underwent uneventful phacoemulsification and in-the-bag intraocular lens implantation. Unlike patients in the control group (43 eyes), patients in the study group (42 eyes) were injected with intracameral 0.01% carbachol during surgery. Spectral-domain optical coherence tomography (OCT) was used to analyze the parameters of CMT, TMV and RVC. On the first postoperative day, mean CMT and TMV decreased markedly in the carbachol group, though these values did not change significantly in the control group. During follow-up visits, no statistically significant differences between the groups occurred regarding changes in mean CMT (p = 0.25, first day; p = 0.80, first week; p = 0.95, first month). However, change in mean TMV between groups on the first postoperative day was statistically significant (p = 0.01, first day; p = 0.96, first week; p = 0.68, first month). RVC values were similar on the preoperative and postoperative first days in both groups (p > 0.05). Results suggest that the effect of intracameral carbachol on macular OCT is related to pharmacological effects, as well as optic events (e.g. miosis). Intracameral carbachol given during cataract surgery decreases macular thickness and volume in the early postoperative period but does not exert any gross effect on RVC.

OBJECTIVES Iatrogenic subclavian artery puncture following central venous catheterization is a rare but potentially fatal complication. There are very few reports in the literature on this condition. We propose the use of video-assisted thoracic surgery (VATS) in the management of these injuries. METHODS The technique of VATS to manage subclavian artery injury was described. We presented the first reported case of successful repair of subclavian artery injury using VATS. RESULTS Using a two-incisional approach for VATS, the haemothorax was rapidly evacuated and the subclavian artery injury was successfully repaired using pledgetted sutures under direct thoracoscopic visualization. The patient had an uneventful postoperative recovery. CONCLUSIONS VATS can be successfully applied to repair subclavian artery injury. The advantages include rapid intrathoracic access, excellent thoracoscopic visualization of the thoracic inlet, and avoidance of the morbidity associated with open thoracotomy. PMID:23518293

Stage-two surgery using collagen soft tissue grafts: clinical cases and ultrastructural analysis.

To present the application of two different soft tissue grafts around dental implants during stage-two surgery. Furthermore, the ultrastructure of these materials is shown and discussed using scanning electron microscopy (SEM). Although soft tissue autografts may be currently regarded as the gold standard, harvesting of these grafts might lead to higher morbidity, longer chair time, and intra-/postoperative complications at the donor site. New developments in collagen scaff olds have provided an alternative to successfully replace autologous grafts in clinical practice. The SEM pictures clearly show the different composition of a bilayer scaff old (collagen matrix, CM) and a porcine acellular dermal matrix (ADM). These distinctive properties lead to different possible indications. Within the presented cases, ADM was used to augment the ridge contour and was placed into a buccal pouch to achieve complete coverage and an uneventful closed healing. On the other side, CM was left exposed to the oral cavity to successfully gain keratinized mucosa around and between two dental implants.

Low socio-economic group patients from rural areas often opt for free cataract surgeries offered by charitable organisations. SICS continues to be a time tested technique for cataract removal in such patients. In recent times, camp patients are sometimes treated by clear corneal phacoemulsification with implantation of a rigid IOL, which being more cost effective is often provided for camp patients. This study was undertaken to find out which surgical technique yielded better outcomes and was more suited for high volume camp surgery. To find the better surgical option- phacoemulsification with rigid IOL or SICS, in poor patients from rural areas. A prospective randomised controlled trial of cataract patients operated by two different techniques. One hundred and twelve eyes were selected and were randomly allocated into two groups of 56 eyes each. At completion of the study, data was analysed for 52 eyes operated by clear corneal phacoemulsification and implantation of a rigid IOL, and 56 eyes operated by SICS. Unpaired t-test was used to calculate the p- value. The results were evaluated on the following criteria. The mean post-operative astigmatism at the end of four weeks - was significantly higher in phacoemulsification group as compared to SICS group The BCVA (best corrected visual acuity) at the end of four weeks - was comparable in both groups. Subjective complaints and/ or complications: In phaco group two patients required sutures and seven had striate keratitis , while none in SICS group. Complaint of irritation was similar in both groups. Surgical time- was less for SICS group as compared to phaco group. SICS by virtue of being a faster surgery with more secure wound and significantly less astigmatism is a better option in camp patients from rural areas as compared to phacoemulsification with rigid IOL.

Craniopharyngiomas are 5-10 % of all pediatric tumors, but are seldomly encountered in the perinatal period. Only seven instances of a truly antenatal diagnosis of a congenital craniopharyngioma that subsequently underwent radical surgery have been reported. We present the case of a patient who received the diagnosis of a suprasellar tumor during the prenatal period and received radical surgery. We report a case of a neonatal craniopharyngioma treated surgically. The pregnancy progressed uneventfully until a routine ultrasound at 37 weeks of gestation showed a 15 × 15 mm high echoic mass in the center of the fetal head. Neonatal Gd-enhanced T1-weighted MRI at 5 days of life showed a homogenously enhanced mass (16×22×15 mm) in the sellar and suprasellar lesion. As the tumor showed rapid growth at the 3rd month of life, the patient underwent a surgical treatment and the mass was totally removed. Three years later, the physical and mental development of the patient was normal, and Gd-MRI studies showed no tumor recurrence. The present case is the eighth case of a truly antenatal diagnosis of a craniopharyngioma that underwent successful radical surgery. Craniopharyngioma is a benign tumor and thought to be a slow growing tumor in childhood. The results of radical surgery were very poor, and the mortality and morbidity rates were high in the previous reports due to the huge size of tumor at operation. The present case demonstrated the rapid growth in short interval of Gd-MRI. This is the first report of tumor kinetics of congenital craniopharyngioma with previous reports. The calculated tumor doubling time in our case was 37 days.

It is known that smokers and patients with chronic obstructive pulmonary disease (COPD) experience a higher rate of pulmonary-related complications following abdominal surgery. The impact of anesthetic technique (regional [RA] versus general [GA] versus combination of both) on the complication rate has not been established. This study examined the outcomes of abdominal surgery performed using RA (epidural or continuous spinal) as the sole anesthetic technique in patients with severe pulmonary impairment (SPI). We reviewed a series of 8 general surgery cases performed using RA alone (T4-T6 sensory level) in patients with SPI, as evidenced by an forced expiratory volume in 1 second (FEV(1)) less than 50% predicted and/or home oxygen requirement. One patient also received postoperative epidural analgesia. FEV(1) ranged from 0.3 to 1.84 L; 3 patients required home oxygen therapy, and 5 of the 8 were American Society of Anesthesiology (ASA) class 4. Operations included segmental colectomy (n = 2), open cholecystectomy (n = 1), incisional herniorrhaphy (n = 1), and laparoscopic herniorrhaphy (n = 4). Intraoperative conditions were adequate with RA alone for successful completion of the procedure in all cases. All patients recovered uneventfully except for 1 who developed postoperative pneumonia that resolved with standard therapy. Length of stay was less than 24 hours for 5 of 8 patients. Mortality was 0%. Abdominal surgery can be safely performed using RA alone in selected high-risk patients, making this option an attractive alternative to GA for those with severe pulmonary impairment.

Although ovarian tumour in the koi (Cyprinus carpio) does not appear to be an uncommon condition, its occurrence and therapy has rarely been reported. In the present case, the decision for surgery was based on clinical and sonographic findings of an intracoelomic mass. We used tricaine methansulfonate for the anaesthesia. Laparotomy was performed by ventral access and an ovarian tumour of 12-cm diameter was removed. The wound was sutured in two layers using Vicryl®. In addition to the application of an analgesic, an antibiotic and vitamins, the postoperative conditions the patient was kept under were adapted to support wound healing. The fish recovered uneventfully and was clinically healthy during the 16-month observation period. Based on the histological findings, the tumour was diagnosed as a thecoma. Investigations using antibodies against vimentin, cytokeratin, S 100 and glial fibrillary acidic protein (GFAP) failed to provide reliable results.

To study the safety and efficacy of 2-port pars plana anterior and central core vitrectomy (Lam floaterectomy) in combination with phacoemulsification (phaco) and intraocular lens implantation (IOL) for patients with cataract and significant floaters under topical anesthesia. Retrospective review of the first 50 consecutive cases. A standardized treatment protocol was used for patients with cataract and significant (moderate to severe) floaters (duration > 3 months). Data analysis included intraoperative and postoperative complications, floater status, and patient satisfaction. There were 50 eyes (38 patients) with a male-to-female ratio of 1 to 2.3. Twelve patients had bilateral eye surgeries. Mean age was 58.10 ± 9.85 years (range, 39-83). All patients completed the 3-month follow-up. One eye had mild vitreous hemorrhage at the end of surgery arising from sclerotomy wound oozing. No other intraoperative compli-cations were encountered. Postoperatively, there was 1 case of transient hypotony and 1 case of congestion at sclerotomy wound. No cases of retinal break or detachment, or clinically significant macular edema, were reported. There were 5 cases (10%) of mild residual floaters and 1 case (2%) of floater recurrence. Total floater clearance rate was 88%. Patient satisfaction rates were 80%, 14%, 6%, and 0% for very satisfied, satis-fied, acceptable, and unsatisfied, respectively. The 3-month results in terms of safety and efficacy of the Lam floaterectomy in combination with phaco and IOLfor patients with cataract and significant floaters under topical anesthesia are encouraging. Further larger-scale, prospective, multicenter studies seem warranted. Copyright© 2017 Asia-Pacific Academy of Ophthalmology.

To evaluate a novel gonioscopy score as a potential predictor for intraocular pressure (IOP) reduction after cataract surgery. Prospective study that included consecutive patients with or without glaucoma, either with open or narrow angles but without peripheral anterior synechiae, who underwent phacoemulsification. Eyes with intraoperative complications and secondary glaucoma were excluded. A preoperative gonioscopy score was created, summing the Shaffer gonioscopy grading in 4 quadrants (range 0-16). To determine variables associated with IOP change at 6 months, univariate and multivariate linear mixed-effects regression analysis was performed adjusting for age, sex, and preoperative IOP. 188 eyes from 137 patients were enrolled. The mean age of the patients was 75.0 (±8.5) years and the average preoperative IOP was 15.6 (±3.6) mm Hg with 0.7 (range 0-4) glaucoma medications. The mean IOP reduction after phaco was 3.0 (±2.6) mm Hg at postoperative month 6. After multivariate analysis, preop IOP (β=0.49 [0.41 - 0.58] P<0.0001), gonioscopy score (β=-0.17 [-0.24 - -0.09] P<0.0001), ACD (β=-0.88 [-1.64 - -0.14] P=0.02) and IOP/ACD ratio (β=0.45 [0.07 - 0.83] P=0.021) were associated with IOP reduction at 6 months. Preoperative predictors for IOP reduction after cataract surgery were preoperative IOP, ACD, gonioscopy score and IOP/ACD ratio. The IOP/ACD ratio and gonioscopy score can be easy parameters to obtain and may help clinicians to estimate the IOP reduction after phaco.

Liver gas gangrene is a rare condition with a highly mortality rate. It is mostly associated with host factors, such as malignancy and immunosuppression. A 57-year-old female was admitted to our hospital with abnormalities of her serum hepato-biliary enzymes. She had a history of hypertension, diabetes mellitus, cerebral infarction, and chronic renal failure. She was diagnosed with bile duct cancer of the liver hilum and a left hepatectomy was carried out, with extrahepatic bile duct resection. Initially her post-operative state was uneventful. However, she suddenly developed melena with anemia on post-operative day (POD) 18. A Computed tomography (CT) examination on POD 19 revealed a massive build up of gas and portal gas formation in the anterior segment of the liver. Although we immediately provided the drainage and a probe laparotomy, she died on POD 20 due to shock with disseminated intravascular coagulation. Liver gas gangrene is rare and has a high mortality rate. This case seems to have arisen from an immunosuppressive state after major surgery with biliary reconstruction for bile duct cancer and subsequent gastrointestinal bleeding, leading to gas gangrene of the liver.

To determine the influence of age and the corneal stromal refractive index on the difference between the predicted and actual postoperative refractive error after laser in situ keratomileusis (LASIK) and whether the precision of outcomes could be improved by considering age and the refractive index. Vissum Instituto Oftalmologico de Alicante, Alicante, Spain. Case series. Flaps were created using a mechanical microkeratome. The stromal refractive index was measured using a VCH-1 refractometer after flap lifting. Refractive data were obtained 1, 3, and 6 months postoperatively. Uneventful LASIK was performed in 133 eyes. The mean age, refractive index, and applied corrections were 33.4 years ± 9.49 (SD), 1.368 ± 0.006, and -2.43 ± 3.36 diopters (D), respectively. The difference between the predicted and actual postoperative refractive error = 2.315-0.021 age-1.106 refractive index (F = 3.647, r = 0.254, P=.029; n = 109) at 1 month and = 11.820-0.023 age-7.976 refractive index (F = 3.392, r = 0.261, P=.022, n = 106) at 3 months. A correlation between the actual and calculated postoperative refraction improved from r = -0.178 (P=.064; n = 75) to r = -0.418 (P<.001) after considering the true refractive index 6 months postoperatively. The predicted outcomes of LASIK can be improved by inputting the refractive index of the individual corneal stroma. Unexpected outcomes (>0.50 D) of LASIK could be avoided by considering patient age and the refractive index and by adjusting the applied correction accordingly. Copyright © 2012 ASCRS and ESCRS.

Surgeons may be unaware of the ability of plant toxins to cause corneal damage. Therefore, corneal damage following intraocular surgery due to plant toxins may be misdiagnosed as postoperative infection. A 74-year-old man presented with hyperemia and reduced visual acuity in both eyes 6 weeks after uneventful cataract surgery. We observed extensive hyperemia and corneal stromal edema with Descemet's folds in both eyes. After obtaining a detailed patient history, we diagnosed plant toxin-induced corneal edema due to Asclepias physocarpa, which can induce corneal edema by inhibiting the Na + /K + ATPase activity of the corneal endothelium. Antimicrobial and steroid eye drops and an oral steroid were prescribed accordingly. Symptons began to improve on day 3 and had almost completely resolved by day 6. At 1 month, the patient had fully recovered without any sequelae. The correct diagnosis was possible in the present case as symptoms were bilateral and the patient was able to report his potential exposure to plant toxins. However, if the symptoms had been unilateral and the patient had been unaware of these toxins, he may have undergone unnecessary surgical interventions to treat non-existent postoperative endophthalmitis.

To describe a technique for visualizing fluid turbulence and cavitational energy created by ultrasonic phaco tips. University Eye Clinic of Trieste, Trieste, Italy. Generation of cavitational energy by the phaco tip was visualized using an optical test bench comprising several components. The technique uses a telescope system to expand a laser light source into a coherent, collimated beam of light with a diameter of approximately 50.0 mm. The expanded laser beam shines on the test tube containing the tip activated in a medium of water or ophthalmic viscosurgical device (OVD). Two precision optical collimators complete the optical test bench and form the system used to focus data onto a charge-coupled device television camera connected to a recorder. Images of irrigation, irrigation combined with aspiration, irrigation/aspiration, and phacosonication were obtained with the tip immersed in a tube containing water or OVD. Optical image processing enabled acoustic cavitation to be visualized during phacosonication. The system is a possible means of evaluating a single phaco apparatus power setting and comparing phaco machines and techniques.

Purpose To determine the incidence and severity of dry eye as determined by the International Task Force (ITF) scale in patients being screened for cataract surgery. Patients and methods This was a prospective, multi-center, observational study of 136 patients, at least 55 years of age, who were scheduled to undergo cataract surgery. The primary outcome measure was the incidence of dry eye as evaluated by grade on the ITF scale and secondary outcome measures include tear break-up time (TBUT), ocular surface disease index score, corneal staining with fluorescein, conjunctival staining with lissamine green, and a patient questionnaire to evaluate symptoms of dry eye. Results Mean patient age was 70.7 years. A total of 73.5% of patients were Caucasian and 50% were female. Almost 60% had never complained of a foreign body sensation; only 13% complained of a foreign body sensation half or most of the time. The majority of patients (62.9%) had a TBUT ≤5 seconds, 77% of eyes had positive corneal staining and 50% of the eyes had positive central corneal staining. Eighteen percent had Schirmer’s score with anesthesia ≤5 mm. Conclusion The incidence of dry eye in patients scheduled to undergo cataract surgery in a real-world setting is higher than anticipated.

Training within a proficiency-based virtual reality (VR) curriculum may reduce errors during real surgical procedures. This study used a scientific methodology to develop a VR training curriculum for phacoemulsification surgery (PS). Ten novice-(n) (performed <10 cataract operations), 10 intermediate-(i) (50-200), and 10 experienced-(e) (>500) surgeons were recruited. Construct validity was defined as the ability to differentiate between the three levels of experience, based on the simulator-derived metrics for two abstract modules (four tasks) and three procedural modules (five tasks) on a high-fidelity VR simulator. Proficiency measures were based on the performance of experienced surgeons. Abstract modules demonstrated a 'ceiling effect' with construct validity established between groups (n) and (i) but not between groups (i) and (e)-Forceps 1 (46, 87, and 95; P<0.001). Increasing difficulty of task showed significantly reduced performance in (n) but minimal difference for (i) and (e)-Anti-tremor 4 (0, 51, and 59; P<0.001), Forceps 4 (11, 73, and 94; P<0.001). Procedural modules were found to be construct valid between groups (n) and (i) and between groups (i) and (e)-Lens-cracking (0, 22, and 51; P<0.05) and Phaco-quadrants (16, 53, and 87; P<0.05). This was also the case with Capsulorhexis (0, 19, and 63; P<0.05) with the performance decreasing in the (n) and (i) group but improving in the (e) group (0, 55, and 73; P<0.05) and (0, 48, and 76; P<0.05) as task difficulty increased. Experienced/intermediate benchmark skill levels are defined allowing the development of a proficiency-based VR training curriculum for PS for novices using a structured scientific methodology.

To describe the posterior capsule rupture rates and visual outcomes after phacoemulsification, analyze risk factors for poor vision, and compare results of faculty (F) and residents (R). Retrospective audit study. Visual success of all capsule ruptures (2006-2010) was analyzed and compared to uneventful cases. Rupture rates of faculty and residents were compared (χ², P < .05). Success was defined as % best-corrected visual acuity (BCVA) ≥20/40 at 3 months (excluding poor-prognosis eyes) and studied in relation to age, sex, surgeon type, stage of surgery, vitreous loss, dropped nucleus, and other complications (eg, retinal detachment, corneal decompensation, dislocated intraocular lens [IOL]). Final risk factors were identified using multivariate logistic regression analysis. From 2006 to 2010, there were 887 capsule ruptures in 48 377 phacoemulsification cases (rate 1.8%). Uneventful cases had significantly better visual outcomes than capsule ruptures (98.5% vs 93.9%; P < .01). Faculty rupture rates were lower (F = 1.4%) than residents' (R = 3.4%; P < .01), but visual outcomes were similar (F = 93.8%, R = 93.7%; P > .05). Ruptures most frequently occurred during phacoemulsification (59.6%) and irrigation and aspiration (24.8%) stages. Risk factors for poor outcomes included age >65 years, dropped nuclei, and other complications. The overall capsule rupture rate was 1.8%. Although residents had higher rates, visual success matched faculty's, possibly attributable to case mix and close supervision. Associated risk factors for poor vision included age >65 years, dropped nuclei, and postoperative retinal, corneal, and IOL complications. Copyright © 2014 Elsevier Inc. All rights reserved.

Pigmented villonodular synovitis is an extremely rare disease in skeletally immature patients. Erosive destruction of the involved joint leads to early arthritis, and its high recurrence rate makes treatment challenging. Multiple surgical approaches exist, but it is unclear as to which among them achieves the lowest possible recurrence rate and morbidity. We report the case of a 5-year-old girl with left knee pain and swelling who was diagnosed with diffuse pigmented villonodular synovitis of the left knee based on MRI findings. Combined open and arthroscopic surgery was performed to completely remove the tumor. Postoperative histopathological examination confirmed the diagnosis of diffuse pigmented villonodular synovitis. The postoperative course was uneventful, with a gradual improvement in symptoms. There were no signs of recurrence on postoperative MRI performed at the 8-month follow-up, with neither knee pain nor limitation of range of motion. The favorable outcome in this case suggests that combined open and arthroscopic surgery may be an effective method for treating pigmented villonodular synovitis in skeletally immature patients.

While most oral surgical procedures can be safely performed in an outpatient setting, certain medical conditions may present a higher chance of postoperative complications. In particular, those predisposing the patient to bleeding abnormalities pose a potential risk when performing such treatments. The authors report a case involving full-mouth extractions in a patient with cirrhosis and thrombocytopenia after obtaining a platelet transfusion. A 62-year-old Caucasian female presented to a university special care dental clinic requiring extractions. Her pertinent medical history was remarkable for cirrhosis and thrombocytopenia, with a platelet count of 32,000/uL. Upon medical consultation, the patient was appointed for a prophylactic platelet transfusion. The surgery was rendered uneventfully, and the patient achieved adequate hemostasis without hospitalization. Patients with cirrhosis pose a potential bleeding risk with dental surgical procedures. Pre-operative medical consultation, review of pertinent laboratory values, and prophylactic platelet transfusion allow these patients to be managed safely in an outpatient setting. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

To determine the optimal longitudinal power settings for Infiniti OZil Intelligent Phaco (IP) at varying torsional amplitude settings; and to test the hypothesis that increasing longitudinal power is more important at lower torsional amplitudes to achieve efficient phacoemulsification. Laboratory investigation. setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah. procedure: Individual porcine nuclei were fixed in formalin, then cut into 2.0 mm cubes. Lens cube phacoemulsification was done using OZil IP at 60%, 80%, and 100% torsional amplitude with 0%, 10%, 20%, 30%, 50%, 75%, or 100% longitudinal power. All experiments were done using a 20 gauge 0.9 mm bent reverse bevel phaco tip at constant vacuum (550 mm Hg), aspiration rate (40 mL/min), and bottle height (50 cm). main outcome measure: Complete lens particle phacoemulsification (efficiency). Linear regression analysis showed a significant increase in efficiency with increasing longitudinal power at 60% torsional amplitude (R(2) = 0.7269, P = .01) and 80% torsional amplitude (R(2) = 0.6995, P = .02) but not at 100% amplitude (R(2) = 0.3053, P = .2). Baseline comparison of 60% or 80% vs 100% torsional amplitude without longitudinal power showed increased efficiency at 100% (P = .0004). Increasing longitudinal power to 20% abolished the efficiency difference between 80% vs 100% amplitudes. In contrast, 75% longitudinal power abolished the efficiency difference between 60% vs 100% torsional amplitudes. Results suggest that longitudinal power becomes more critical at increasing phacoemulsification efficiencies at torsional amplitudes less than 100%. Increasing longitudinal power does not further increase efficiency at maximal torsional amplitudes. Copyright © 2014 Elsevier Inc. All rights reserved.

To evaluate whether an ophthalmologist-led, non-anesthesia-supported, limited monitoring pathway for phacoemulsification/intraocular lens cataract surgery, can be performed safely with only a medical emergency team providing support. Retrospective, observational, cohort study. All patients who underwent elective phacoemulsification/intraocular lens surgery under topical anesthesia in the ophthalmology outpatient unit between January 1, 2011, and December 31, 2012. Cataract surgery was performed by phacoemulsification under topical anesthesia. The intake process mainly embraced ophthalmic evaluation, obtaining a medical history, and proposing the procedure. A staff ophthalmologist performed the procedure assisted by 2 registered nurses in an independent outpatient clinic operating room within the hospital. The clinical pathway was without dedicated presence of or access to anesthesia service. Perioperative monitoring was limited to blood pressure and plethysmography preoperatively and intraoperatively. Patients were offered supportive care and instructed to avoid fasting and continue all their chronic medication. The primary outcome measure was the incidence of adverse events requiring medical emergency team (MET) interventions throughout the pathway. Secondary outcome measures were surgical ocular complication rates, use of oral sedatives, and reported reasons to perform the surgery in the classical operation room complex. Within the cataract pathway, 6961 cases (4347 patients) were eligible for analysis. Three MET interventions related to the phacoemulsification/intraocular lens pathway occurred in the 2-year study period, resulting in an intervention rate of 0.04%. None of the interventions was intraoperative. All 3 patients were diagnosed as vasovagal collapse and recuperated uneventfully. No hospital admittance was required. Eight other incidents occurred within the general ophthalmology outpatient unit population during the study period. Cataract surgery can

To measure the working frequency and the stroke dynamics of the phaco tip of 3 phacoemulsification machines. University Eye Clinic of Trieste, Italy. Experimental study. A video wet fixture was assembled to measure the working frequency using a micro camera and a micropulsed strobe-light system. A different video wet fixture was created to measure tip displacement as vectorial movement at different phaco powers using a microscopic video apparatus. The working frequency of the Infiniti Ozil machine was 43.0 kHz in longitudinal mode and 31.6 kHz in torsional mode. The frequency of the Whitestar Signature machine was 29.0 kHz in longitudinal mode and 38.0 kHz with the Ellips FX handpiece. The Stellaris machine had a frequency of 28.8 kHz. The longitudinal stroke of the 3 machines at different phaco powers was statistically significantly different. The Stellaris machine had the highest stroke extent (139 μm). The lateral movement of the Infiniti Ozil and Whitestar Signature machines differed significantly. No movement on the y-axis was observed for the Infiniti Ozil machine in torsional mode. The elliptical path of the Ellips FX handpiece had different x and y components at different phaco powers. The 3 phaco machines performed differently in terms of working frequency and stroke dynamics. The knowledge of the peculiar lateral and elliptical path strokes of Infiniti and Whitestar Signature machines may allow the surgeon to fully use these features for lens removal.

Cardiovascular effects of total intravenous anesthesia using ketamine-medetomidine-propofol drug combination (KMP-TIVA) were determined in 5 Thoroughbred horses undergoing surgery. The horses were anesthetized with intravenous administration (IV) of ketamine (2.5 mg/kg) and midazolam (0.04 mg/kg) following premedication with medetomidne (5 µg/kg, IV) and artificially ventilated. Surgical anesthesia was maintained by controlling propofol infusion rate (initially 0.20 mg/kg/min following an IV loading dose of 0.5 mg/kg) and constant rate infusions of ketamine (1 mg/kg/hr) and medetomidine (1.25 µg/kg/hr). The horses were anesthetized for 175 ± 14 min (range from 160 to 197 min). Propofol infusion rates ranged from 0.13 to 0.17 mg/kg/min, and plasma concentration (Cpl) of propofol ranged from 11.4 to 13.3 µg/ml during surgery. Cardiovascular measurements during surgery remained within clinically acceptable ranges in the horses (heart rate: 33 to 37 beats/min, mean arterial blood pressure: 111 to 119 mmHg, cardiac index: 48 to 53 ml/kg/min, stroke volume: 650 to 800 ml/beat and systemic vascular resistance: 311 to 398 dynes/sec/cm5). The propofol Cpl declined rapidly after the cessation of propofol infusion and was significantly lower at 10 min (4.5 ± 1.5 µg/ml), extubation (4.0 ± 1.2 µg/ml) and standing (2.4 ± 0.9 µg/ml) compared with the Cpl at the end of propofol administration (11.4 ± 2.7 µg/ml). All the horses recovered uneventfully and stood at 74 ± 28 min after the cessation of anesthesia. KMP-TIVA provided satisfactory quality and control of anesthesia with minimum cardiovascular depression in horses undergoing surgery. PMID:25409552

Primary small intestinal volvulus is defined as torsion in the absence of congenital malrotation, band, or postoperative adhesions. Its occurrence as an early postoperative complication is rare. A 40-year-old woman presented with rectal prolapse, and laparoscopic rectopexy was uneventfully performed. She could not have food on the day after surgery. She started oral intake on postoperative day 3 but developed abdominal pain after the meal. Contrast-enhanced CT revealed torsion of the small intestinal mesentery. An emergent laparotomy showed small intestinal volvulus, without congenital malformation or intestinal adhesions. We diagnosed it as primary small intestinal volvulus. The strangulated intestine was resected, and reconstruction was performed. The patient recovered uneventfully after the second surgery. To the best of our knowledge, this is the first report of primary small intestinal volvulus occurring after rectopexy for rectal prolapse. Primary small intestinal volvulus could be a postoperative complication after laparoscopy. © 2018 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

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

Early differentiation between sepsis and systemic inflammatory response syndrome (SIRS) is useful for therapeutic management in neonates and infants after surgery. To compare the early (first 2 days) diagnostic value of interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) after surgery in the differentiation of subsequent SIRS and septic complications. IL-6, PCT, and CRP were measured 0, 24, and 48 hours after surgery in neonates and infants with clinical suspicion of postoperative sepsis. Sensitivity, specificity, and predictive values for SIRS/septic complications were calculated. A total of 31 out of 205 neonates and infants showed clinical signs for postoperative sepsis and underwent sepsis work-up. Nine patients developed septic complications, sixteen patients met criteria for SIRS, and six patients showed an uneventful postoperative course during the first five postoperative days. IL-6, PCT, and CRP levels increased in all subgroups after surgery and were significantly higher in the sepsis group (p < 0.05). IL-6 peaked immediately, CRP at 24 to 48 hours, and PCT at 24 hours after surgery. Sensitivity and specificity (area under the curve) for IL-6 (cutoff 673 ng/dL) were 94.4 and 75% (86.2%), for CRP (cutoff 1.48 mg/dL) 76.2 and 75.0% (88.1%), and for PCT (cutoff 16.1 mg/L) 66.7 and 57.1% (65.6%). IL-6 appears to be an early marker for severe bacterial infections with high sensitivity. IL-6 and CRP were the most reliable markers for the discrimination between SIRS and sepsis within the postoperative period. Georg Thieme Verlag KG Stuttgart · New York.

Splenic involvement secondary to blunt abdominal trauma is often treated by performing a splenectomy. The severity of the post-splenectomy syndrome is currently well known (blood loss, sepsis), so there is an increasing tendency to preserve the spleen. The case is presented of splenic preservation after blunt abdominal trauma with hilum involvement, emphasising the role of Floseal as a haemostatic agent, as well as the use of resorbable meshes to preserve the spleen. A 22-year-old woman presenting with a grade IV splenic lesion secondary to a blunt abdominal trauma after a traffic accident. Partial splenic resection was performed and bleeding was controlled with Floseal and use of a reinforcing polyglycolic acid mesh. No postoperative complications occurred, being discharged on day 5. The long-term follow-up has been uneventful. The use of haemostatic agents such as thrombin and the gelatine gel (FloSeal) and the use of polyglycolic acid meshes enable spleen-preserving surgery, making it a feasible and reproducible procedure and an alternative to classical splenectomy.

Patients with thrombotic thrombocytopenic purpura (TTP), Moschowitz's disease, run a high risk of perioperative bleeding and need intensive hematologic support. In some patients, TTP is associated with cancer but the surgical role in these patients is still unclear. To illustrate the surgical problems and outcome we present the case histories of three patients with TTP observed in our emergency department. Two patients had TTP secondary to cancer and one patient with primary TTP (no evidence of neoplasia) had emergency operation for gastric hemorrhage, occlusion and TTP unresponsive to plasmapheresis. The first two patients who had not radical resection of cancer and no splenectomy, died for TTP complications. The third patient who underwent emergency splenectomy, had an uneventful postoperative course and TTP completely regressed. These case reports suggest that patients with TTP should be screened to rule out cancer. In patients with acute cancer-related complications emergency surgery should aim to resect the cancer. An associated splenectomy may increase the effectiveness of postoperative hematologic therapy.

Carcinoma arising in lingual thyroid is an extremely rare entity accounting for only 1% of all reported ectopic thyroids. Here, we report a case of carcinoma arising in lingual thyroid, which has been successfully managed by transoral resection and bilateral neck dissections. A lingual mass 4-cm in diameter with calcification was incidentally detected by computed tomography at medical check-up. No thyroid tissue was observed in normal position. Ultrasound examination showed bilateral multiple lymphadenopathies. Fine needle aspiration biopsy from lymph node in his right neck was diagnosed as Class III and thyroglobulin level of the specimen was 459ng/ml. Due to the difficulty in performing FNA of the lingual masses, right neck dissection was performed in advance for diagnostic purpose. Pathological examination showed existence of large and small follicular thyroid tissues in several lymph nodes, suggesting lymph node metastasis from thyroid carcinoma. Two months after the initial surgery, video-assisted transoral resection of lingual thyroid with simultaneous left neck dissection was performed. Postoperative course was uneventful. Papillary carcinoma was found in the lingual thyroid and thyroid tissues were also found in left cervical lymph nodes. Video-assisted transoral resection was useful for the treatment of thyroid cancer arising in lingual thyroid. Copyright © 2018 Elsevier B.V. All rights reserved.

A 25-year-old hypertensive female patient was referred to our institution. Initial workup exams demonstrated a 2.8 cm cortical lower pole tumor in the right kidney. She underwent laparoscopic partial nephrectomy without complications. Histopathologic examination revealed a rare juxtaglomerular cell tumor known as reninoma. After surgery, she recovered uneventfully and all medications were withdrawn. Case hypothesis: Secondary arterial hypertension is a matter of great interest to urologists and nephrologists. Renovascular hypertension, primary hyperadosteronism and pheocromocytoma are potential diagnosis that must not be forgotten and should be excluded. Although rare, chronic pyelonephritis and renal tumors as rennin-producing tumors, nephroblastoma, hypernephroma, and renal cell carcinoma might also induce hypertension and should be in the diagnostic list of clinicians. Promising future implications: Approximately 5% of patients with high blood pressure have specific causes and medical investigation may usually identify such patients. Furthermore, these patients can be successfully treated and cured, most times by minimally invasive techniques. This interesting case might expand knowledge of physicians and aid better diagnostic care in future medical practice.

Middle colic artery (MCA) aneurysms are very rare and exclusively reported with symptoms or rupture. We report successful laparoscopic elective surgery for both cecal cancer and MCA aneurysm in an 87-year-old man who presented with bloody stools. Diagnostic colonoscopy revealed a cecal tumor 40 mm in diameter that was histologically confirmed as a well-differentiated adenocarcinoma. The three-phase dynamic computed tomography showed a cecal tumor without any metastasis and an MCA aneurysm 10 mm in diameter. Radical right hemicolectomy with D3 lymph node dissection that included the MCA aneurysm was performed. The postoperative course was uneventful, and the patient survived without recurrence. Even though the present patient was very elderly, the postoperative course of laparoscopic radical surgery for both an MCA aneurysm and cecal cancer was uneventful with good short-term outcomes.

We present the first transgastric peritoneoscopy in a 20-year-old man. The objectives were to evaluate the impact of the site of viscerotomy on the technical feasibility of natural orifice transluminal endoscopic surgery (NOTES), assess transgastric peritoneoscopy as a complementary procedure, determine the safety and efficacy of NOTES, and attempt inspection/biopsy of the gallbladder. The patient was admitted with a benign gastric outlet obstruction, chronic cholecystitis and radiological suspicion of a mass in the gallbladder which was not visualised on diagnostic laparoscopy. Complementary transgastric peritoneoscopy was performed to gain deeper penetration of the tumour with the flexible tip of the gastroscope. The visceral "aperture" was created in the antrum where gastrojejunal anastomosis would be fashioned. Laparoscopic transillumination of the anterior gastric wall facilitated this part of the procedure. During transgastric peritoneoscopy, the gallbladder and structures in the upper and left hemi-abdomen appeared retrograde due to the unusual location of the gastrotomy. The right hemi-abdomen and pelvis were easily examined with a "straight shaft" approach. The gallbladder could not be identified with exploratory laparoscopy and transgastric peritoneoscopy. Due to risk of visceral injury, open gastrojejunal anastomosis and cholecystectomy were performed. Intraoperatively, an inflamed, thick-walled gallbladder was found adherent to the proximal duodenum. Transgastric peritoneoscopy was safely performed in our patient. The postoperative course was uneventful. Our patient showed significant improvement at 13 weeks after surgery without any procedure-related complication. In conclusion, transgastric peritoneoscopy may be used to complement diagnostic laparoscopy. Laparoscopic assistance during transluminal access facilitates simple tasks inside the peritoneal cavity to be performed safely.

Purpose To compare intraocular pressure (IOP) after trabectome-mediated ab interno trabeculectomy surgery in phakic patients (T) and trabectome with same session phacoemulsification (PT) using Coarsened Exact Matching. Although phacoemulsification is associated with IOP reduction when performed on its own, it is not known how much it contributes in PT. Methods Subjects were divided into phakic T and PT. Exclusion criteria were follow-up for <12 months and additional glaucoma surgery. Demographics were compared by the Mann-Whitney U test and chi-squared test for continuous and categorical variables, respectively. Multiple imputation was utilized to avoid eliminating data with missing values. Groups were then matched using Coarsened Exact Matching based on age, race, type of glaucoma, baseline IOP, and number of preoperative glaucoma medications. Univariate linear regression was used to examine IOP reduction after surgery; those variables that were statistically significant were included in the final multivariate regression model. Results A total of 753 cases were included (T: 255, PT: 498). When all variables except for age were kept constant, there was an additional IOP reduction of 0.05±0.01 mmHg conferred for every yearly increment in age. Every 1 mmHg increase in baseline IOP correlated to an additional IOP reduction of 0.80±0.02 mmHg. Phacoemulsification was not found to be a statistically significant contributor to IOP when comparing T and PT (p≥0.05). T had a 21% IOP reduction to 15.9±3.5 mmHg (p<0.01) while PT had an 18% reduction to 15.5±3.6 mmHg (p<0.01). Number of medications decreased (p<0.01) in both groups from 2.4±1.2 to 1.9±1.3 and from 2.3±1.1 to 1.7±1.3, respectively. Conclusion Phacoemulsification does not make a significant contribution to postoperative IOP or number of medications when combined with trabectome surgery in phakic patients. PMID:26895293

Several small, enclosed reserves in southern Africa are experiencing significant elephant population growth, which has resulted in associated environmental damage and changes in biodiversity. Although several techniques exist to control elephant populations, e.g., culling, relocation, and immunocontraception, the technique of laparoscopic vasectomy of free-ranging bull elephants was investigated. Bilateral vasectomies were performed in 45 elephants. Of these elephants, one died within 24 hr of recovery and two had complications during surgery but recovered uneventfully. Histologic examination confirmed the resected tissue as ductus deferens in all the bulls. Most animals recovered uneventfully and showed no abnormal behavior after surgery. Complications recorded included incisional dehiscence, 1 full-thickness and 2 partial-thickness lacerations of the large intestine, and initial sling-associated complications, for example, deep radial nerve paresis. One bull was found dead 6 weeks after surgery without showing any prior abnormal signs. Vasectomy in free-ranging African bull elephants may be effectively performed in their normal environment. The surgical procedure can be used as a realistic population management tool in free-ranging elephants without major anesthetic, surgical, or postoperative complications.

To compare the efficacy of a topical nonsteroidal antiinflammatory drug, topical corticosteroid, and a combination of both drugs to prevent the occurrence of cystoid macular edema (CME) after cataract surgery in nondiabetic patients. Twelve European study centers. Randomized clinical trial. Nondiabetic patients having uneventful cataract surgery were included in this study. Patients were randomized to receive topical bromfenac 0.09% twice daily for 2 weeks or dexamethasone 0.1% 4 times daily with 1 drop less per day every following week, or a combination of both. The primary outcome was the difference in central subfield mean macular thickness 6 weeks postoperatively. Secondary outcome measures included corrected distance visual acuity as well as the incidence of CME and clinically significant macular edema (CSME) within 6 weeks and 12 weeks postoperatively. This study comprised 914 patients. Six weeks postoperatively, the central subfield mean macular thickness was 288.3 μm, 296.0 μm, and 284.5 μm in the bromfenac group, dexamethasone group, and combination treatment group, respectively (overall P = .006). The incidence of clinically significant macular edema within 12 weeks postoperatively was 3.6%, 5.1%, and 1.5%, respectively (overall P = .043). Patients treated with a combination of topical bromfenac 0.09% and dexamethasone 0.1% had a lower risk for developing CSME after cataract surgery than patients treated with a single drug.

Visual function is determined by a combination of the cornea, which has a larger effect and internal aberrations generated by the intraocular lens and those induced by the surgery. These corneal refractive changes are related to the location and size of the corneal incision. The smaller the incision, the lower the aberrations and the better the optical quality. To compare the effect of uneventful coaxial versus biaxial microincision cataract surgery (MICS) on the corneal aberrations. Retrospective interventional nonrandomized comparative case study comprised 40 eyes of 36 patients with primary senile cataract. They were divided into two groups: Group I (20 eyes) had operated by biaxial MICS and Group II (20 eyes) had operated by coaxial MICS. Each group were assessed by corneal topography and wavefront analysis over 6 mm pupil size preoperatively and 1-month postoperatively. Statistical analysis was performed using SPSS for Windows (version 17.0.1, SPSS, Inc.). The paired t-test was used to compare the mean values of corneal aberrations preoperatively and 1-month postoperatively in each group. There was a significant increase in trefoil and quatrefoil in biaxial MICS (P = 0.063, 0.032 respectively) while other aberrations insignificantly changed. The coaxial MICS showed a significant increase in root mean square (RMS) of total high order aberrations (HOAs) (P = 0.02) and coma (0.028), but not the others. In comparison to each other, there was the insignificant difference as regards astigmatism, RMS of individual and total HOAs. Coaxial and biaxial MICS are neutral on corneal astigmatism and aberrations.

Surgery can only maintain its role in a highly competitive environment if results are continuously improved, accompanied by further reduction of the interventional trauma for patients and with justifiable costs. Significant impulse to achieve this goal was expected from minimally invasive surgery and, in particular, robotic surgery; however, a real breakthrough has not yet been achieved. Accordingly, the new strategic approach of cognitive surgery is required to optimize the provision of surgical treatment. A full scale integration of all modules utilized in the operating room (OR) into a comprehensive network and the development of systems with technical cognition are needed to upgrade the current technical environment passively controlled by the surgeon into an active collaborative support system (surgery 4.0). Only then can the true potential of minimally invasive surgery and robotic surgery be exploited.

Lack of access to emergency and essential surgery is widespread in low- and middle-income countries. Scarce anesthesia services contribute to this unmet need. The aim of this study was to evaluate the safety and feasibility of the Every Second Matters for Emergency and Essential Surgery-Ketamine (ESM-Ketamine) package for emergency and essential procedures when no anesthetist was available. From November 2013 to September 2017, the ESM-Ketamine package was used for patients requiring emergency or life-improving surgeries in fifteen selected facilities across Kenya when no anesthetist was available. A mixed-methods approach was used to assess safety and feasibility of the ESM-Ketamine package, including demand, acceptability, and practicality. The primary outcome was ketamine-related adverse events. Key-informant interviews captured perceptions of providers, hospital administrators, and surgeons/proceduralists. Non-anesthetist mid-level providers used ESM-Ketamine for 1216 surgical procedures across the fifteen study facilities. The median ketamine dose was 2.1 mg/kg. Brief (<30 s) oxygen desaturations occurred in 39 patients (3%), and prolonged (>30 s) oxygen desaturations occurred in seven patients (0.6%). There were 157 (13%) reported cases of hallucinations and agitation which were treated with diazepam. All patients recovered uneventfully, and no ketamine-related deaths were reported. Twenty-seven key-informant interviews showed strong support for the program with four main themes: financial considerations, provision of services, staff impact, and scaling considerations. The ESM-Ketamine package appears safe and feasible and is capable of expanding access to emergency and essential surgeries in rural Kenya when no anesthetist is available.

To compare phacoemulsification parameters of torsional and longitudinal ultrasound modes. Ophthalmology Department, Military Health Service Institute, Warsaw, Poland. This prospective study evaluated eyes 1, 7, and 30 days after phacoemulsification with an Infiniti Vision System using the torsional or longitudinal ultrasound (US) mode. Cataract classification was according to the Lens Opacities Classification System II. Nucleus fragmentation was by the phaco-chop and quick-chop methods. Primary outcome measures were phaco time, mean phaco power, mean torsional amplitude, and aspiration time. Total energy, defined as cumulative dissipated energy (CDE) x aspiration time, and the effective coefficient, defined as aspiration time/phaco time, were also calculated. Four hundred eyes were evaluated. The CDE was statistically significantly lower in the torsional mode for nucleus grades I, II, and III (P<.001) but not for grade IV (P>.05). Aspiration time was statistically significantly shorter in the torsional mode than in the longitudinal mode for nucleus grades III and IV (P<.05). Total energy was significantly lower in the torsional mode for all nucleus densities (P<.05). The effective coefficient was significantly lower in the longitudinal mode except for nucleus grade I (P<.05). Torsional phacoemulsification was more effective than longitudinal phacoemulsification in the amount of applied fluid and the quantity of US energy expended. With the torsional method, it was possible to maintain a constant ratio of amount of fluid flow to quantity of US energy used, regardless of nucleus density.

The common practice of short-cycle sterilization for ophthalmic surgical instrumentation has come under increased regulatory scrutiny. This study was undertaken to evaluate the efficacy of short-cycle sterilization processing for consecutive same-day cataract procedures. Testing of specific sterilization processing methods by an independent medical device validation testing laboratory. Phaco handpieces from 3 separate manufacturers were tested along with appropriate biologic indicators and controls using 2 common steam sterilizers. A STATIM 2000 sterilizer (SciCan, Canonsburg, PA) with the STATIM metal cassette, and an AMSCO Century V116 pre-vacuum sterilizer (STERIS, Mentor, OH) using a Case Medical SteriTite container (Case Medical, South Hackensack, NJ) rigid container were tested using phaco tips and handpieces from 3 different manufacturers. Biological indicators were inoculated with highly resistant Geobacillus stearothermophilus, and each sterility verification test was performed in triplicate. Both wrapped and contained loads were tested with full dry cycles and a 7-day storage time to simulate prolonged storage. In adherence with the manufacturers' instructions for use (IFU), short cycles (3.0-3.5-minute exposure times) for unwrapped and contained loads were also tested after only 1 minute of dry time to simulate use on a consecutive case. Additional studies were performed to demonstrate whether any moisture present in the load containing phaco handpieces postprocessing was sterile and would affect the sterility of the contents after a 3-minute transit/storage time. This approximated the upper limit of time needed to transfer a containment device to the operating room. Presence or absence of microbial growth from cultured test samples. All inoculated test samples from both sterilizers were negative for growth of the target organism whether the full dry phase was interrupted or not. Pipetted postprocessing moisture samples and swabs of the handpieces were

Many insurance companies have considerable prebariatric surgery requirements despite a lack of evidence for improved clinical outcomes. The hypothesis of this study is that insurance-specific requirements will be associated with a decreased progression to surgery and increased delay in time to surgery. Retrospective data collection was performed for patients undergoing bariatric surgery evaluation from 2010-2015. Patients who underwent surgery (SGY; n = 827; mean body mass index [BMI] 49.1) were compared with those who did not (no-SGY; n = 648; mean BMI: 49.4). Univariate and multivariate analysis were performed to identify specific co-morbidity and insurance specific predictors of surgical dropout and time to surgery. A total of 1475 patients using 12 major insurance payors were included. Univariate analysis found insurance requirements associated with surgical drop out included longer median diet duration (no-SGY = 6 mo; SGY = 3 mo; P<.001); primary care physician letter of necessity (P<.0001); laboratory testing (P = .019); and evaluation by cardiology (P<.001), pulmonology (P<.0001), or psychiatry (P = .0003). Using logistic regression to control for co-morbidities, longer diet requirement (odds ratio [OR] .88, P<.0001), primary care physician letter (OR .33, P<.0001), cardiology evaluation (OR .22, P = .038), and advanced laboratory testing (OR 5.75, P = .019) independently predicted surgery dropout. Additionally, surgical patients had an average interval between initial visit and surgery of 5.8±4.6 months with significant weight gain (2.1 kg, P<.0001). Many prebariatric surgery insurance requirements were associated with lack of patient progression to surgery in this study. In addition, delays in surgery were associated with preoperative weight gain. Although prospective and multicenter studies are needed, these findings have major policy implications suggesting insurance requirements may need to be reconsidered to improve medical care.

Over the past decade, plastic surgery programs have continued to evolve with the addition of 1 year of training, increase in the minimum number of required aesthetic cases, and the gradual replacement of independent positions with integrated ones. To evaluate the impact of these changes on aesthetic training, a survey was sent to residents and program directors. A 37 question survey was sent to plastic surgery residents at all Accreditation Council for Graduate Medical Education-approved plastic surgery training programs in the United States. A 13 question survey was sent to the program directors at the same institutions. Both surveys were analyzed to determine the duration of training and comfort level with cosmetic procedures. Eighty-three residents (10%) and 11 program directors (11%) completed the survey. Ninety-four percentage of residents had a dedicated cosmetic surgery rotation (an increase from 68% in 2015) in addition to a resident cosmetic clinic. Twenty percentage of senior residents felt they would need an aesthetic surgery fellowship to practice cosmetic surgery compared with 31% in 2015. Integrated chief residents were more comfortable performing cosmetic surgery cases compared with independent chief residents. Senior residents continue to have poor confidence with facial aesthetic and body contouring procedures. There is an increase in dedicated cosmetic surgery rotations and fewer residents believe they need a fellowship to practice cosmetic surgery. However, the comfort level of performing facial aesthetic and body contouring procedures remains low particularly among independent residents.

Bowel perforation is a rare complication of mid-urethral sling procedures and is usually reported shortly after the surgery. We report a remotely discovered asymptomatic bowel injury found at the time of subsequent surgery. The patient with a history of several prior pelvic surgeries underwent an uneventful retropubic mid-urethral sling placement. Five years later, during an abdominal sacrocolpopexy procedure, mesh from the mid-urethral sling was found perforating the wall of the cecum and fixating it to the right pelvic sidewall. Cecal wedge resection was performed to excise the sling mesh. Asymptomatic bowel perforation by mid-urethral sling mesh has not been previously reported. Pelvic and abdominal surgeons should be aware of the possibility of finding this injury in patients with prior sling surgeries.

Complete rupture of a papillary muscle following acute myocardial infarction is a severe complication that is typically associated with acute left ventricular failure, pulmonary edema, and relentless clinical deterioration. The reported mortality rates without surgical intervention is almost 90%, therefore, prompt operation without prolonged attempts at medical stabilization is the key to decrease operative mortality. Although the complete coronary revascularization in conjunction with mitral valve replacement is advocated in the western medical academic society, there is only a few case of conjunct surgery has been reported in Japan. Three successful cases of conjunct surgery of mitral valve replacement and coronary complete revascularization in acute phase within one week from the onset of acute myocardial infarction (AMI) are described. There were one male and two female patients with an average age of 60-year-old (range 48-67), who developed cardiogenic shock and admitted to our hospital. The average interval between onset of AMI and the appearance of mitral regurgitation (MR) was 38 hours, and that of the appearance of MR and admission was 40 hours. Surgeries were performed within 26 hours (average 13 hours) after admission. The mitral valve was replaced with a mechanical valve (St. Jude Medical Valve) and a complete coronary revasculatization was done using saphenous vein graft. The average period of operation time and aortic cross clamping time were 6 hours 22 minutes and 109 minutes respectively. The average number of coronary grafting was 2.3 (range 1-3). Postoperative recovery from cardiogenic shock was uneventful in all three patients. The average periods of ICU stay and hospital stay were 5 days and 43 days respectively. All patients have regained their social activities with mean follow up period of 52 months. Since ischemic heart disease remains the leading cause of death in such patients, it is suggested that complete coronary revascularization

Do we need to establish guidelines for patients with neuromodulation implantable devices, including spinal cord stimulators undergoing nonspinal surgeries?

PubMed Central

Ghaly, Ramsis F.; Tverdohleb, Tatiana; Candido, Kenneth D.; Knezevic, Nebojsa Nick

2016-01-01

Background: Spinal cord stimulation is currently approved to treat chronic intractable pain of the trunk and limbs. However, such implantable electronic devices are vulnerable to external electrical currents and magnetic fields. Within the hospitals and modern operating rooms (ORs), there is an abundance of electrical devices and other types of equipment that could interfere with such devices. Despite the increasing number of patients with neuromodulation implantable devices, there are no written guidelines available or consensus of cautions for such patients undergoing unrelated surgery. Case Descriptions: A 60-year-old female with a permanent St. Jude's spinal cord stimulator (SCS) presented for open total abdominal hysterectomy. Both the anesthesia and gynecology staffs were aware of the device presence, but were unaware of any precautions regarding intraoperative management. The device was found to be nonmagnetic resonance imaging compatible, and bipolar cautery was used instead of monopolar cautery. A 59-year-old female with a 9-year-old permanent Medtronic SCS, presented for right total hip arthroplasty. The device was switched off prior to entering the OR, bipolar cautery was used, and grounding pads were placed away from her battery site. In each case, the manufacturer's representative was contacted preoperative. Both surgeries proceeded uneventfully. Conclusions: The Food and Drug Administration safety information manual warns about the use of diathermy, concomitant implanted stimulation devices, lithotripsy, external defibrillation, radiation therapy, ultrasonic scanning, and high-output ultrasound, all of which can lead to permanent implant damage if not turned off prior to undertaking procedures. Lack of uniform guidelines makes intraoperative management, as well as remote anesthesia care of patients with previously implanted SCSs unsafe. PMID:26958424

Variable Operative Experience in Hand Surgery for Plastic Surgery Residents.

PubMed

Silvestre, Jason; Lin, Ines C; Levin, Lawrence Scott; Chang, Benjamin

Efforts to standardize hand surgery training during plastic surgery residency remain challenging. We analyze the variability of operative hand experience at U.S. plastic surgery residency programs. Operative case logs of chief residents in accredited U.S. plastic surgery residency programs were analyzed (2011-2015). Trends in fold differences of hand surgery case volume between the 10th and 90th percentiles of residents were assessed graphically. Percentile data were used to calculate the number of residents achieving case minimums in hand surgery for 2015. Case logs from 818 plastic surgery residents were analyzed of which a minority were from integrated (35.7%) versus independent/combined (64.3%) residents. Trend analysis of fold differences in case volume demonstrated decreasing variability among procedure categories over time. By 2015, fold differences for hand reconstruction, tendon cases, nerve cases, arthroplasty/arthrodesis, amputation, arterial repair, Dupuytren release, and neoplasm cases were below 10-fold. Congenital deformity cases among independent/combined residents was the sole category that exceeded 10-fold by 2015. Percentile data suggested that approximately 10% of independent/combined residents did not meet case minimums for arterial repair and congenital deformity in 2015. Variable operative experience during plastic surgery residency may limit adequate exposure to hand surgery for certain residents. Future studies should establish empiric case minimums for plastic surgery residents to ensure hand surgery competency upon graduation. Copyright © 2017 Association of Program Directors in Surgery.

Maxillary surgery to correct dentofacial deformity has been practiced for almost 100 years. Significant advances have made maxillary surgery a safe and efficient means of correcting midface deformities. Anesthetic techniques, specifically hypotensive anesthesia, have allowed for safer working conditions. Landmark studies have proven manipulation and segmentalization of the maxilla is safe and allowed this surgery to become a mainstay in corrective jaw surgery. This article provides an overview of surgical techniques and considerations as they pertain to maxillary surgery for orthognathic surgery. Segmental surgery, openbite closure, vertical excess, grafting, and a technology update are discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

The association of hypno-anesthesia and conventional anesthesia in a patient with multiple allergies at risk of anaphylactic shock.

PubMed

Antonelli, Carlo; Luchetti, Marco; De Trana, Luigi

2014-01-01

A male patient needed surgery for the ablation of 4 impacted maxillary molars that prevented chewing and had contributed to progressively worsening trigeminal neuralgia. Two previous anesthetic procedures led to episodes of severe anaphylactic shock with the need for a prolonged stay in the ICU. Hypnotic anesthesia was therefore selected as a safer option for this patient. After 4 preparative sessions, on the day of surgery, the hypnotist provided an induction followed by suggestions for mouth and face anesthesia. Intubation occurred following the introduction of remifentanil and sevoflurane. The surgery lasted about 90 minutes and proceeded uneventfully. This case report describes how conventional and hypnotic anesthesia may work synergistically and may be particularly advantageous in case of drug allergy.

Towards cybernetic surgery: robotic and augmented reality-assisted liver segmentectomy.

PubMed

Pessaux, Patrick; Diana, Michele; Soler, Luc; Piardi, Tullio; Mutter, Didier; Marescaux, Jacques

2015-04-01

Augmented reality (AR) in surgery consists in the fusion of synthetic computer-generated images (3D virtual model) obtained from medical imaging preoperative workup and real-time patient images in order to visualize unapparent anatomical details. The 3D model could be used for a preoperative planning of the procedure. The potential of AR navigation as a tool to improve safety of the surgical dissection is outlined for robotic hepatectomy. Three patients underwent a fully robotic and AR-assisted hepatic segmentectomy. The 3D virtual anatomical model was obtained using a thoracoabdominal CT scan with a customary software (VR-RENDER®, IRCAD). The model was then processed using a VR-RENDER® plug-in application, the Virtual Surgical Planning (VSP®, IRCAD), to delineate surgical resection planes including the elective ligature of vascular structures. Deformations associated with pneumoperitoneum were also simulated. The virtual model was superimposed to the operative field. A computer scientist manually registered virtual and real images using a video mixer (MX 70; Panasonic, Secaucus, NJ) in real time. Two totally robotic AR segmentectomy V and one segmentectomy VI were performed. AR allowed for the precise and safe recognition of all major vascular structures during the procedure. Total time required to obtain AR was 8 min (range 6-10 min). Each registration (alignment of the vascular anatomy) required a few seconds. Hepatic pedicle clamping was never performed. At the end of the procedure, the remnant liver was correctly vascularized. Resection margins were negative in all cases. The postoperative period was uneventful without perioperative transfusion. AR is a valuable navigation tool which may enhance the ability to achieve safe surgical resection during robotic hepatectomy.

Minimally invasive surgery fellowships offer experience in robotic surgery, the nature of which is poorly defined. The objective of this survey was to determine the current status and opportunities for robotic surgery training available to fellows training in the United States and Canada. Sixty-five minimally invasive surgery fellows, attending a fundamentals of fellowship conference, were asked to complete a questionnaire regarding their demographics and experiences with robotic surgery and training. Fifty-one of the surveyed fellows completed the questionnaire (83 % response). Seventy-two percent of respondents had staff surgeons trained in performing robotic procedures, with 55 % of respondents having general surgery procedures performed robotically at their institution. Just over half (53 %) had access to a simulation facility for robotic training. Thirty-three percent offered mechanisms for certification and 11 % offered fellowships in robotic surgery. One-third of the minimally invasive surgery fellows felt they had been trained in robotic surgery and would consider making it part of their practice after fellowship. However, most (80 %) had no plans to pursue robotic surgery fellowships. Although a large group (63 %) felt optimistic about the future of robotic surgery, most respondents (72.5 %) felt their current experience with robotic surgery training was poor or below average. There is wide variation in exposure to and training in robotic surgery in minimally invasive surgery fellowship programs in the United States and Canada. Although a third of trainees felt adequately trained for performing robotic procedures, most fellows felt that their current experience with training was not adequate.

Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

Model surgery with a passive robot arm for orthognathic surgery planning.

PubMed

Theodossy, Tamer; Bamber, Mohammad Anwar

2003-11-01

The aims of the study were to assess the degree of accuracy of model surgery performed manually using the Eastman technique and to compare it with model surgery performed with the aid of a robot arm. Twenty-one patients undergoing orthognathic surgery gave consent for this study. They were divided into 2 groups based on the model surgery technique used. Group A (52%) had model surgery performed manually, whereas group B (48%) had their model surgery performed using the robot arm. Patients' maxillary casts were measured before and after model surgery, and results were compared with those for the original treatment plan in horizontal (x-axis), vertical (y-axis), and transverse (z-axis) planes. Statistical analysis using Mann-Whitney U test for x- and y-axis and independent sample t test for z-axis have shown significant differences between both groups in x-axis (P =.024) and y-axis (P =.01) but not in z-axis (P =.776). Model surgery performed with the aid of a robot arm is significantly more accurate in anteroposterior and vertical planes than is manual model surgery. Robot arm has an important role to play in orthognathic surgery planning and in determining the biometrics of orthognathic surgical change at the model surgery stage.

Enhanced recovery after surgery is a multimodal perioperative strategy according to the evidence-based medicine and multidisciplinary collaboration, aiming to improve the restoration of functional capacity after surgery by reducing surgical stress, optimal control of pain, early oral diet and early mobilization. Compared with other sub-specialty in general surgery, pancreatic surgery is characterized by complex disease, highly difficult procedure and more postoperative complications. Accordingly, pancreatic surgery shares a slow development in enhanced recovery after surgery. In this review, the feasibility, safety, application progress, prospect and controversy of enhanced recovery after surgery in pancreatic surgery are discussed.

The breakthrough in laparoscopic surgery has been the development of a charge-coupled device camera system and Mouret performing cholecystectomy in 1987. The short-term benefits of laparoscopic surgery are widely accepted and the long-term benefit of less incidence of bowel obstruction can be expected. The important developments have been the articulating instrumentation via new laparoscopic access ports. Since 2007, single-incision laparoscopic surgery has spread all over the world. Not only single-scar but also no-scar operation is a current topic. In 2004, Kalloo reported the flexible transgastric peritoneoscopy as a novel approach to therapeutic interventions. In 2007, Marescaux reported transvaginal cholecystectomy in a patient. The breakthrough in robotic surgery was the development of the da Vinci Surgical System. It was introduced to Keio University Hospital in March 2000. Precision in the surgery will reach a higher level with the use of robotics. In collaboration with the faculty of technology and science, Keio University, the combined master-slave manipulator has been developed. The haptic forceps, which measure the elasticity of organs, have also been developed. The first possible sites of lymphatic metastasis are known as sentinel nodes. Otani reported vagus-sparing segmental gastrectomy under sentinel node navigation. This kind of function-preserving surgery will be performed frequently if the results of the multicenter prospective trial of the dual tracer method are favorable. Indocyanine green fluorescence-guided method using the HyperEye charge-coupled device camera system can be a highly sensitive method without using the radioactive colloid. 'Minimally invasive, function-preserving and precise surgery under sentinel node navigation in community hospital' may be a goal for us.

Anesthesia and surgery in a Quarter Horse affected with hyperkalemic periodic paralysis resulted in euthanasia after 7 days of postoperative recumbency. Initial recovery was uneventful after extensive sinus surgery, but within 2 hours, the horse had severe muscle weakness. Plasma electrolyte concentrations were within the normal range during the period of recumbency. There was no clinical or laboratory evidence of severe muscle damage. Despite treatment with acetazolamide, isoproterenol, and intensive nursing, the horse was unable to stand for more than a few seconds and developed severe decubital ulcers. Ultrastructural examination revealed nemaline rods and swollen mitochondria in disrupted myofibers.

Unnecessary surgery.

Leape, L L

1989-01-01

The extent of unnecessary surgery has been the object of considerable speculation and occasional wild accusation in recent years. Most evidence of the existence of unnecessary surgery, such as information from studies of geographic variations and the results of second surgical opinion programs, is circumstantial. However, results from the few studies that have measured unnecessary surgery directly indicate that for some highly controversial operations the fraction that are unwarranted could be as high as 30 percent. Most unnecessary surgery results from physician uncertainty about the effectiveness of an operation. Elimination of this uncertainty requires more efficient production and dissemination of scientific information about clinical effectiveness. In the absence of adequate data from scientific studies, the use of a consensus of expert opinion, disseminated by means of comprehensive practice guidelines, offers the best opportunity to identify and eliminate unnecessary surgery.

2008-01-01

Robotic colorectal surgery has gradually been performed more with the help of the technological advantages of the da Vinci® system. Advanced technological advantages of the da Vinci® system compared with standard laparoscopic colorectal surgery have been reported. These are a stable camera platform, three-dimensional imaging, excellent ergonomics, tremor elimination, ambidextrous capability, motion scaling, and instruments with multiple degrees of freedom. However, despite these technological advantages, most studies did not report the clinical advantages of robotic colorectal surgery compared to standard laparoscopic colorectal surgery. Only one study recently implies the real benefits of robotic rectal cancer surgery. The purpose of this review article is to outline the early concerns of robotic colorectal surgery using the da Vinci® system, to present early clinical outcomes from the most current series, and to discuss not only the safety and the feasibility but also the real benefits of robotic colorectal surgery. Moreover, this article will comment on the possible future clinical advantages and limitations of the da Vinci® system in robotic colorectal surgery. PMID:19108010

Spontaneous spinal subdural hematomas are rare. Their occurrence in a child with congenital von Willebrand disease and the complication of their surgery by a large secondary syringomyelia have never been previously reported. A 13-year-old girl with congenital von Willebrand disease presented to our emergency department in January 2011 for sudden onset of severe back pain centered in her thoracic spine rapidly aggravated by signs of acute myelopathy without any precipitating factor. MRI scan revealed a thoracic subdural collection anterior to the spinal cord at the T7-T9 level, hyperintense on T1- and T2-weighted sequences consistent with an acute spinal subdural hemorrhage. Evacuation of the subdural hematoma was realized immediately after hemostasis parameter correction, and post-operative course was uneventful with full functional recovery. One year later, the patient presented once again but with progressive and more severe myelopathy caused by a large syringomyelia extending from the T5 level to the conus medullaris. A syringopleural shunting was performed and the patient was unrolled under an intensive care and rehabilitation program. Her condition remarkably improved and she became able to walk independently within 2 weeks post-operatively. von Willebrand disease should be included as a possible factor of spontaneous spinal subdural hemorrhage. Surgery is advised in emergency and can be associated with remarkable recovery especially in children. Delayed syringomyelia can complicate the post-operative course and can be successfully addressed by syringopleural shunting. Long-term clinical and radiological follow-up is advocated.

Aim  Pneumatosis intestinalis (PI) is a condition in which multiple gas-filled cysts form within the wall of the gastrointestinal tract in either the subserosa or submucosa. The presence of pneumoperitoneum in the presence of PI can present a therapeutic dilemma. The aim of our study was to review our experience and management of this condition. Methods  A single-center retrospective study of consecutive children (> 1 year) presenting with a pneumoperitoneum and evidence of PI (2009-2015). Demographics, case notes, microbiology, and imaging were reviewed. Results  Seven patients were identified (four males; age range 5-14 years). Four children had global developmental delay and were percutaneous endoscopic gastrostomy or jejunostomy fed, one was immunocompromised (acute lymphoblastic leukemia). The others had encephalitis and eosinophilic gastroenteritis. One patient proceeded to an exploratory laparotomy; no perforation was identified, pneumatosis of the colon was observed, and a loop ileostomy was formed. The remaining six were managed conservatively and made nil by mouth with intravenous antibiotics commenced. Five of the six had a computed tomography (CT) scan which revealed PI and free air with no other worrying signs. One died from nongastrointestinal causes, while the remaining five had feeds reintroduced uneventfully. Conclusion  Free air in the setting of PI may represent rupture of the gas cysts and not always transmural perforation. Surgery may not always be indicated and conservative management may suffice. A CT scan can be useful for excluding other intra-abdominal pathological findings and continued clinical assessment is essential. Georg Thieme Verlag KG Stuttgart · New York.

The evolving application of single-port robotic surgery in general surgery.

Advances in the field of minimally invasive surgery have grown since the original advent of conventional multiport laparoscopic surgery. The recent development of single incision laparoscopic surgery remains a relatively novel technique, and has had mixed reviews as to whether it has been associated with lower pain scores, shorter hospital stays, and higher satisfaction levels among patients undergoing procedures through cosmetically-appeasing single incisions. However, due to technical difficulties that arise from the clustering of laparoscopic instruments through a confined working space, such as loss of instrument triangulation, poor surgical exposure, and instrument clashing, uptake by surgeons without a specific interest and expertise in cutting-edge minimally invasive approaches has been limited. The parallel use of robotic surgery with single-port platforms, however, appears to counteract technical issues associated with single incision laparoscopic surgery through significant ergonomic improvements, including enhanced instrument triangulation, organ retraction, and camera localization within the surgical field. By combining the use of the robot with the single incision platform, the recognized challenges of single incision laparoscopic surgery are simplified, while maintaining potential advantages of the single-incision minimally invasive approach. This review provides a comprehensive report of the evolving application single-port robotic surgery in the field of general surgery today. © 2013 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Applications of piezoelectric surgery in endodontic surgery: a literature review.

2014-03-01

Piezosurgery (piezoelectric bone surgery) devices were developed to cut bone atraumatically using ultrasonic vibrations and to provide an alternative to the mechanical and electrical instruments used in conventional oral surgery. Indications for piezosurgery are increasing in oral and maxillofacial surgery, as in other disciplines, such as endodontic surgery. Key features of piezosurgery instruments include their ability to selectively cut bone without damaging adjacent soft tissue, to provide a clear operative field, and to cut without generating heat. Although piezosurgery instruments can be used at most stages of endodontic surgery (osteotomy, root-end resection, and root-end preparation), no published data are available on the effect of piezosurgery on the outcomes of endodontic surgery. To our knowledge, no study has evaluated the effect of piezosurgery on root-end resection, and only 1 has investigated root-end morphology after retrograde cavity preparation using piezosurgery. We conducted a search of the PubMed and Cochrane databases using appropriate terms and keywords related to the use and applications of piezoelectric surgery in endodontic surgery. A hand search also was conducted of issues published in the preceding 2 years of several journals. Two independent reviewers obtained and analyzed the full texts of the selected articles. A total of 121 articles published between January 2000 and December 2013 were identified. This review summarizes the operating principles of piezoelectric devices and outlines the applications of piezosurgery in endodontic surgery using clinical examples. Piezosurgery is a promising technical modality with applications in several aspects of endodontic surgery, but further studies are necessary to determine the influence of piezosurgery on root-end resection and root-end preparation.

Purpose To compare surgical efficiency and multiple early clinical outcome variables in eyes undergoing phacoemulsification using either transversal or torsional ultrasound systems. Setting Assil Eye Institute, Beverly Hills, CA, USA. Design Prospective, randomized, clinician-masked, contralaterally controlled single-center evaluation. Patients and methods Patients seeking cataract removal in both eyes with implantation of multifocal intraocular lenses were randomly assigned to one of two treatment rooms for phacoemulsification with either a transverse ultrasound system or torsional handpiece system. The contralateral eye was treated at a later date with the alternate device. A total of 54 eyes of 27 patients having similar degrees of cataract, astigmatism, and visual potential were included. All operative data were collected for analysis, and patients were followed for 3 months after surgery. Results Similar visual acuity was reported at all postoperative visits between the two groups. Mean phacoemulsification time and total power required were both significantly lower with the transverse system than with the torsional technique (P<0.05 for both). Similarly, mean total balanced salt solution used was significantly less with the transverse system vs torsional (P<0.05). Postoperative safety demonstrated significantly lower endothelial cell loss at 1 day and 1 month (P<0.05) with transverse vs torsional. Macular swelling was less at 1 week, 1 month, and 3 months with transverse vs torsional, although the difference did not achieve significance (P=0.1) at any single time point. Clinically detectable corneal edema was reported less frequently at all postoperative time points with the transverse system. Conclusion The transverse ultrasound system was found to be possibly associated with less balanced salt-solution use, less phacoemulsification time, and less power required than the torsional phaco system.

2004-01-01

Nine unicameral bone cysts of the calcaneus in children were managed surgically using the technique of continuous decompression with titanium cannulated cancellous screws. The average age of the patients at surgery was 12.8 years. At follow-up a minimum of 2 years after surgery, eight cysts showed complete healing; one patient showed healing with residuals. Irritation at the screw insertion site necessitated early removal of the screw in one patient; implant-related problems were not observed in the other patients. Patients were allowed to bear weight after surgery. Implant extraction was performed after full consolidation of the cyst and was uneventful in all patients. A review of the literature and the different treatment modalities used for managing calcaneal cysts is also presented.

A comparative direct cost analysis of pediatric urologic robot-assisted laparoscopic surgery versus open surgery: could robot-assisted surgery be less expensive?

Cost in healthcare is an increasing and justifiable concern that impacts decisions about the introduction of new devices such as the da Vinci(®) surgical robot. Because equipment expenses represent only a portion of overall medical costs, we set out to make more specific cost comparisons between open and robot-assisted laparoscopic surgery. We performed a retrospective, observational, matched cohort study of 146 pediatric patients undergoing either open or robot-assisted laparoscopic urologic surgery from October 2004 to September 2009 at a single institution. Patients were matched based on surgery type, age, and fiscal year. Direct internal costs from the institution were used to compare the two surgery types across several procedures. Robot-assisted surgery direct costs were 11.9% (P=0.03) lower than open surgery. This cost difference was primarily because of the difference in hospital length of stay between patients undergoing open vs robot-assisted surgery (3.8 vs 1.6 days, P<0.001). Maintenance fees and equipment expenses were the primary contributors to robotic surgery costs, while open surgery costs were affected most by room and board expenses. When estimates of the indirect costs of robot purchase and maintenance were included, open surgery had a lower total cost. There were no differences in follow-up times or complication rates. Direct costs for robot-assisted surgery were significantly lower than equivalent open surgery. Factors reducing robot-assisted surgery costs included: A consistent and trained robotic surgery team, an extensive history of performing urologic robotic surgery, selection of patients for robotic surgery who otherwise would have had longer hospital stays after open surgery, and selection of procedures without a laparoscopic alternative. The high indirect costs of robot purchase and maintenance remain major factors, but could be overcome by high surgical volume and reduced prices as competitors enter the market.

European endocrine surgery in the 150-year history of Langenbeck's Archives of Surgery.

2010-04-01

Founded in 1861 as a German language scientific forum of exchange for European surgeons, Langenbeck's Archives of Surgery quickly advanced to become the premier journal of thyroid surgery before World War I, serving as a point of crystallization for the emerging discipline of endocrine surgery. During the interwar period and, in particular, in the first decades after World War II, Langenbeck's Archives of Surgery lost its dominant position as an international and European medium of publication of top quality articles in the area of endocrine surgery. Nevertheless, the journal remained the chief publication organ of German language articles in the field of endocrine surgery. After a series of key events, Langenbeck's Archives of Surgery managed to reclaim its former position as the leading European journal of endocrine surgery: (1) the formation of endocrine surgery in the early 1980s as a subdiscipline of general and visceral surgery; (2) the change of the language of publication from German to English in 1998; and (3) the journal's appointment in 2004 as the official organ of publication of the European Society of Endocrine Surgeons. All in all, the 150-year publication record of Langenbeck's Archives of Surgery closely reflects the history of European Endocrine Surgery. Following the path of seminal articles from Billroth, Kocher, and many other surgical luminaries published in the journal more than 100 years ago, Langenbeck's Archives of Surgery today stands out as the principal European journal in the field of endocrine surgery.

Open surgery for aneurysms of the splenic artery at the hilum of the spleen: Report of three cases.

2018-05-18

Aneurysms of the splenic artery (SAA) located at the hilum of the spleen are not well fit for endovascular or laparoscopic treatment. Open surgery may still be the best option of treatment. We report the cases of 3 female patients of a mean age of 59 years (range, 45-68 years) with a hilar (n = 2) or parahilar (n = 1) SAA undergoing successful open surgical resection, through a short left subcostal access. Recovery was uneventful and mean, postoperative length of stay was 4 days (range, 3-5 days). Results of this report support surgical resection and splenectomy for the treatment of SAA located at the hilum of the spleen. For this particular location endovascular treatment may not be advised, as coil embolization can be followed by a massive splenic infarction precipitating the need for splenectomy, due to the exclusion of backflow from the left gastroepiploic artery through the short gastric vessels. As well, endovascular exclusion through insertion of an endograft may not be feasible due to the absence of a distal landing zone, as stent grafting requires a normal caliber artery of sufficient length on each side of the aneurysm. Surgical excision and splenectomy, through a short subcostal incision, remains a viable option of treatment for hilar SAA. Copyright © 2018. Published by Elsevier Ltd.

The WHO describes health as physical, mental and social well being. Ever since the establishment of plastic surgery aesthetic surgery has been an integral part of this medical specialty. It aims at reconstructing subjective well-being by employing plastic surgical procedures as described in the educational code and regulations for specialists of plastic surgery. This code confirms that plastic surgery comprises cosmetic procedures for the entire body that have to be applied in respect of psychological exploration and selection criteria. A wide variety of opinions resulting from very different motivations shows how difficult it is to differentiate aesthetic surgery as a therapeutic procedure from beauty surgery as a primarily economic service. Jurisdiction, guidelines for professional conduct and ethical codes have tried to solve this question. Regardless of the intention and ability of the health insurances, it has currently been established that the moral and legal evaluation of advertisements for medical procedures depends on their purpose: advertising with the intent of luring patients into cosmetic procedures that do not aim to reconstruct a subjective physical disorder does not comply with a medical indication. If, however, the initiative originates with the patient requesting the amelioration of a subjective disorder of his body, a medical indication can be assumed.

Ambulatory surgery centers deliver surgical care more efficiently than hospitals but may increase overall procedure use and adversely affect competing hospitals. Motivated by these concerns we evaluated how opening of an ambulatory surgery center impacts stone surgery use in a health care market and assessed the effect of its opening on the patient mix at nearby hospitals. In a 100% sample of outpatient surgery from Florida we measured annual stone surgery use between 1998 and 2006. We used multiple regression to determine if the rate of change in use differed between markets, defined by the hospital service area, without and with a recently opened ambulatory surgery center. Stone surgery use increased an average of 11 procedures per 100,000 individuals per year (95% CI 1-20, p <0.001) after an ambulatory surgery center opened in a hospital service area. Four years after opening the relative increase in the stone surgery rate was approximately 64% higher (95% CI 27 to 102) in hospital service areas where a center opened vs hospital service areas without a center. These market level increases in surgery were not associated with decreased surgical volume at competing hospitals and the absolute change in patient disease severity treated at nearby hospitals was small. While opening of an ambulatory surgery center did not appear to have an overly detrimental effect on competing hospitals, it led to a significant increase in the population based rate of stone surgery in the hospital service area. Possible explanations are the role of physician financial incentives and unmet surgical demand. 2010 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Specialty procedures constitute one eighth of rural surgery practice. Currently, general surgeons intending to practice in rural hospitals may not get adequate training for specialty procedures, which they will be expected to perform. Better definition of these procedures will help guide rural surgery training. Current Procedural Terminology codes for all surgical procedures for 81% of North Dakota and South Dakota rural surgeons were entered into the Dakota Database for Rural Surgery. Specialty procedures were analyzed and compared with the Surgical Council on Resident Education curriculum to determine whether general surgery training is adequate preparation for rural surgery practice. The Dakota Database for Rural Surgery included 46,052 procedures, of which 5,666 (12.3%) were specialty procedures. Highest volume specialty categories included vascular, obstetrics and gynecology, orthopedics, cardiothoracic, urology, and otolaryngology. Common procedures in cardiothoracic and vascular surgery are taught in general surgical residency, while common procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology are usually not taught in general surgery training. Optimal training for rural surgery practice should include experience in specialty procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology. Copyright © 2012 Elsevier Inc.

2008-01-01

Minimally invasive ″keyhole″ surgery performed using endoscopic visualization is increasing in popularity and is being used by almost all surgical subspecialties. Within ophthalmology, however, endoscopic surgery is not commonly performed and there is little literature on the use of the endoscope in orbital surgery. Transorbital use of the endoscope can greatly aid in visualizing orbital roof lesions and minimizing the need for bone removal. The endoscope is also useful during decompression procedures and as a teaching aid to train orbital surgeons. In this article, we review the history of endoscopic orbital surgery and provide an overview of the technique and describe situations where the endoscope can act as a useful adjunct to orbital surgery.

Computed tomography scan showed an occupation located at the left lower lobe and adenocarcinoma project from the lobe bronchus was diagnosed by bronchoscope examination. A sleeve lobectomy was performed using the Da Vinci surgical system and the postoperative recovery was uneventful. Robotic thoracic surgery is feasible to perform sleeve lobectomy inspite of inadequate experience.

In the cases of two gynecomastia liposuction patients in which a water-based lubricating gel was used on the liposuction incisions, the incisions failed to heal. For both patients, workup uncovered palisading granulomas at the lateral inframammary fold incision sites several months after otherwise successful surgeries. These two cases are presented and the previous literature is reviewed, with consideration given to the etiology and prevention of such granulomas.

To study and assess clinical outcomes of various modes of treatment for perforated giant gastric ulcer in an emergency setting. From May 2010 to February 2013, 20 cases of perforated giant gastric ulcer (> 2 cm) were operated on in an emergency setting. All the patients presented with features of peritonitis and were resuscitated aggressively before taking for surgery. In the first 4 cases, primary closure was done after taking a biopsy and among these, the 3(rd) case also underwent partial distal gastrectomy and gastrojejunostomy and the 4(th) case underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy for malignancy. All the remaining 16 cases underwent partial distal gastrectomy and gastrojejunostomy. Among the first 4 cases, 2 had an uneventful recovery and were discharged on the 6(th) postoperative day. The 3(rd) and 4(th) patients developed gastric fistula, leading to prolonged hospitalization. For the 3(rd) patient, conservative management was tried for 1 wk, followed by partial distal gastrectomy and gastrojejunostomy, and he was discharged on the 20(th) day after admission, while the 4(th) patient underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy. Postoperatively, he developed adult respiratory distress syndrome, multiorgan dysfunction syndrome and expired on the 3(rd) postoperative day of the second surgery. All the remaining 16 patients underwent partial distal gastrectomy and gastrojejunostomy and recovered well. Among these, 4 of them were malignant and the remaining were benign ulcers. All had an uneventful recovery. The percentage of malignancy in our series was 30% (6 out of 20 cases). In our study, 86% had an uneventful recovery, complications were seen in about 10%, and mortality was about 5%. In giant gastric ulcer, the chances of malignancy and leak after primary closure are high. So, we feel that partial distal gastrectomy and gastrojejunostomy is better.

To understand how physician ownership of ambulatory surgery centers (ASCs) relates to surgery use. Using the State Ambulatory Surgery Databases, we identified patients undergoing outpatient surgery for urinary stone disease in Florida (1998-2002). We empirically derived a measure of physician ownership and externally validated it through public data. We employed linear mixed models to examine the relationship between ownership status and surgery use. We measured how a urologist's surgery use varied by the penetration of owners within his local health care market. Owners performed a greater proportion of their surgeries in ASCs than nonowners (39.6 percent versus 8.0 percent, p<.001), and their utilization rates were over twofold higher ( p<.001). After controlling for patient differences, an owner averaged 16.32 (95 percent confidence interval [CI], 10.98-21.67; p<.001) more cases annually than did a nonowner. Further, for every 10 percent increase in the penetration of owners within a urologist's local health care market, his annual caseload increased by 3.32 (95 percent CI, 2.17-4.46; p<.001). These data demonstrate a significant association between physician ownership of ASCs and increased surgery use. While its interpretation is open to debate, one possibility relates to the financial incentives of ownership. Additional work is necessary to see if this is a specialty-specific phenomenon.

Objective: To review the history, development, and current applications of robotics in surgery. Background: Surgical robotics is a new technology that holds significant promise. Robotic surgery is often heralded as the new revolution, and it is one of the most talked about subjects in surgery today. Up to this point in time, however, the drive to develop and obtain robotic devices has been largely driven by the market. There is no doubt that they will become an important tool in the surgical armamentarium, but the extent of their use is still evolving. Methods: A review of the literature was undertaken using Medline. Articles describing the history and development of surgical robots were identified as were articles reporting data on applications. Results: Several centers are currently using surgical robots and publishing data. Most of these early studies report that robotic surgery is feasible. There is, however, a paucity of data regarding costs and benefits of robotics versus conventional techniques. Conclusions: Robotic surgery is still in its infancy and its niche has not yet been well defined. Its current practical uses are mostly confined to smaller surgical procedures. PMID:14685095

Pancreatic surgery.

To summarize published research on pancreatic surgery over the past year. A number of studies aiming to reduce the costs associated with pancreatic surgery were reported. Retrospective analyses confirmed previous findings that neither the routine use of pancreatic duct stents decreases the rate of fistula formation nor does placement of a drain at the time of surgery change the morbidity in patients who develop one. Minimally invasive approaches, both laparoscopic and robot-assisted, are being performed more frequently to remove pancreatic cancers. A randomized trial confirmed that reinforcement of stapled closure during distal pancreatectomy reduces the rate of fistula formation. Controversy remains over whether small pancreatic neuroendocrine tumors need to be surgically resected or can be treated nonoperatively. Patients with chronic pancreatitis should be screened thoroughly before being offered surgical treatment; two studies reported preoperative factors that can be used to identify those most likely to experience pain relief. Studies published on pancreatic surgery last year focused on a wide-range of topics. The morbidity and mortality of patients undergoing pancreatic surgery continues to improve, and we anticipate that incorporation of these new findings will lead to even better outcomes.

Background People with atrial fibrillation (AF) often undergo cardiac surgery for other underlying reasons and are frequently offered concomitant AF surgery to reduce the frequency of short- and long-term AF and improve short- and long-term outcomes. Objectives To assess the effects of concomitant AF surgery among people with AF who are undergoing cardiac surgery on short-term and long-term (12 months or greater) health-related outcomes, health-related quality of life, and costs. Search methods Starting from the year when the first “maze” AF surgery was reported (1987), we searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library (March 2016), MEDLINE Ovid (March 2016), Embase Ovid (March 2016), Web of Science (March 2016), the Database of Abstracts of Reviews of Effects (DARE, April 2015), and Health Technology Assessment Database (HTA, March 2016). We searched trial registers in April 2016. We used no language restrictions. Selection criteria We included randomised controlled trials evaluating the effect of any concomitant AF surgery compared with no AF surgery among adults with preoperative AF, regardless of symptoms, who were undergoing cardiac surgery for another indication. Data collection and analysis Two review authors independently selected studies and extracted data. We evaluated the risk of bias using the Cochrane ‘Risk of bias’ tool. We included outcome data on all-cause and cardiovascular-specific mortality, freedom from atrial fibrillation, flutter, or tachycardia off antiarrhythmic medications, as measured by patient electrocardiographic monitoring greater than three months after the procedure, procedural safety, 30-day rehospitalisation, need for post-discharge direct current cardioversion, health-related quality of life, and direct costs. We calculated risk ratios (RR) for dichotomous data with 95% confidence intervals (CI) using a fixed-effect model when heterogeneity was low (I2 ≤ 50%) and random

Staged corrective surgery for complex congenital scoliosis and split cord malformation

2009-01-01

Congenital scoliosis associated with split cord malformation raises the issue on how to best manage these patients to avoid neurologic injury while achieving satisfactory correction. We present the case of a 12-year-old girl who first presented when she was 11-year old with such combination but without much physical handicap or neurological deficit. The corrective surgery offered at that time was refused by the family. She again presented after 1 year with documented severe aggravation of the curve resulting in unstable walking and psychological upset. Her imaging studies showed multiple malformations in lower cervical and thoracic spine and a split cord malformation type 2 (fibrous septum with diplomyelia) at the apex of the deformity. A one-stage correction was deemed neurologically too risky. We therefore performed during a first stage a thoracotomy with anterior release. This was followed by skeletal traction with skull tongs and bilateral femoral pins. After gradual increase in traction weights a reasonable correction was achieved without any neurological deficit, over the next 10 days. A second-stage operation was done on the 11th day and a posterior instrumented fusion was performed. Post-operative recovery was uneventful and there were no complications. She was discharged with a Boston Brace to be worn for 3 months. At 2-year follow-up the patient outcome is excellent with excellent balance and correction of the deformity. In this grand round case, we discuss all the different option of treatment of congenital scoliosis associated with split cord malformation. In a medical environment where spinal cord monitoring is lacking, we recommend an initial release followed by skull and bifemoral traction over several days to monitor the neurologic status of the patient. Once optimal correction is achieved with the traction, a posterior instrumentation can be safely done. PMID:19626347

Drain tube migration into the anastomotic site of an esophagojejunostomy for gastric small cell carcinoma: short report

PubMed Central

2010-01-01

Background Intraluminal migration of a drain through an anastomotic site is a rare complication of gastric surgery. Case Presentation We herein report the intraluminal migration of a drain placed after a lower esophagectomy and total gastrectomy with Roux-en-Y anastomosis for gastric small cell carcinoma. Persistent drainage was noted 1 month after surgery, and radiographic studies were consistent with drain tube migration. Endoscopy revealed the drain had migrated into the esophagojejunostomy anastomotic site. The drain was removed from outside of abdominal wound while observing the anastomotic site endoscopically. The patient was treated with suction via a nasogastric tube drain for 5 days, and thereafter had an uneventful recovery. Conclusions Though drain tube migration is a rare occurrence, it should be considered in patients with persistent drainage who have undergone gastric surgery. PMID:20492665

The media play a vital role in public education. The predominant image they portray of plastic and reconstructive surgery is that of cosmetic surgery, whilst the specialty's true scope is often misrepresented. The aim was to evaluate portrayal of plastic surgery in the national newspapers. LexisNexis Professional search engine was used to retrieve articles from all UK newspapers published in 2006 that contained the term 'plastic surgery' and each article was analysed. Of 1191 articles, 89% used the term 'plastic surgery' in the context of cosmetic surgery and only 10% referred to reconstructive work. There were 197 feature articles on cosmetic surgery and 52% of them included a quote from the medical profession. If the quoted doctor was on the UK General Medical Council (GMC) specialist register for plastic surgery, it was significantly more likely that a potential problem or complication associated with cosmetic surgery would be mentioned (p= 0.015). The vast majority of newspaper articles refer only to the cosmetic component of plastic surgery. When quoted, doctors on the GMC specialist register for plastic surgery provide a more balanced view of cosmetic surgery. Further initiative is needed to portray the full scope of plastic and reconstructive surgery to the general public.

Surgery of Crohns disease is an important part of the general treatment algorithm. The role of surgery is changing with the development of conservative procedures. The recent years have seen the return to early treatment of patients with Crohns disease. Given the character of the disease and its intestinal symptoms, a specific approach to these patients is necessary, especially regarding the correct choice of surgery. The paper focuses on the luminal damage of the small and large intestine including complications of the disease. We describe the individual indications for a surgical solution, including the choice of anastomosis or multiple / repeated surgeries.

Nonspecific small bowel ulcers are rare and there have been limited reports. We applied laparoscopic surgery successfully for the perforation caused by this disease of jejunum. A 70-year-old man visited to our hospital with complaint of abdominal pain and fever. He was diagnosed abdominal peritonitis with findings of intraperitoneal gas and fluid. Emergency laparoscopic surgery was performed. A perforation 5mm in diameter was recognized in jejunum opposite side of mesentery. Partial resection of jejunum with end-to-end anastomosis and peritoneal lavage were performed. Pathologically, an ulcer was recognized around the blowout perforation without specific inflammation. He was discharged uneventfully 12days after surgery. Laparoscopic surgery has diagnostic and therapeutic advantages because of its lower invasion with a good operation view, and in case of the small bowel, it is easy to shift extra-corporeal maneuver.

To assess the impact of ambulatory surgery centers (ASCs) on rates of hospital-based outpatient procedures and adverse events. Twenty percent national sample of Medicare beneficiaries. A retrospective study of beneficiaries undergoing outpatient surgery between 2001 and 2010. Health care markets were sorted into three groups-those with ASCs, those without ASCs, and those where one opened for the first time. Generalized linear mixed models were used to assess the impact of ASC opening on rates of hospital-based outpatient surgery, perioperative mortality, and hospital admission. Adjusted hospital-based outpatient surgery rates declined by 7 percent, or from 2,333 to 2,163 procedures per 10,000 beneficiaries, in markets where an ASC opened for the first time (p < .001 for test between slopes). Within these markets, procedure use at ASCs outpaced the decline observed in the hospital setting. Perioperative mortality and admission rates remained flat after ASC opening (both p > .4 for test between slopes). The opening of an ASC in a Hospital Service Area resulted in a decline in hospital-based outpatient surgery without increasing mortality or admission. In markets where facilities opened, procedure growth at ASCs was greater than the decline in outpatient surgery use at their respective hospitals. © Health Research and Educational Trust.

Combined surgery versus cataract surgery alone for eyes with cataract and glaucoma

Background Cataract and glaucoma are leading causes of blindness worldwide, and their co-existence is common in elderly people. Glaucoma surgery can accelerate cataract progression, and performing both surgeries may increase the rate of postoperative complications and compromise the success of either surgery. However, cataract surgery may independently lower intraocular pressure (IOP), which may allow for greater IOP control among patients with co-existing cataract and glaucoma. The decision between undergoing combined glaucoma and cataract surgery versus cataract surgery alone is complex. Therefore, it is important to compare the effectiveness of these two interventions to aid clinicians and patients in choosing the better treatment approach. Objectives To assess the relative effectiveness and safety of combined surgery versus cataract surgery (phacoemulsification) alone for co-existing cataract and glaucoma. The secondary objectives include cost analyses for different surgical techniques for co-existing cataract and glaucoma. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 10), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2014), EMBASE (January 1980 to October 2014), PubMed (January 1948 to October 2014), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to October 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en).

The scope of general surgery practice has evolved tremendously in the last 20 years. However, clinical experience in general surgery residency training has undergone relatively little change. To evaluate the current scope of academic general surgery and its implications on surgical residency. The University HealthSystem Consortium and Association of American Medical Colleges established the Faculty Practice Solution Center (FPSC) to characterize physician productivity. The FPSC is a benchmarking tool for academic medical centers created from revenue data collected from more than 90,000 physicians who practice at 95 institutions across the United States. The FPSC database was queried to evaluate the annual mean procedure frequency per surgeon (PFS) in each calendar year from 2006 through 2011. The associated work relative value units (wRVUs) were also examined to measure physician effort and skill. During the 6-year period, 146 distinct Current Procedural Terminology codes were among the top 100 procedures, and 16 of these procedures ranked in the top 10 procedures in at least 1 year. The top 10 procedures accounted for more than half (range, 52.5%-57.2%) of the total 100 PFS evaluated for each year. Laparoscopic Roux-en-Y gastric bypass was consistently among the top 10 procedures in each year (PFS, 18.2-24.6). The other most frequently performed procedures included laparoscopic cholecystectomy (PFS, 30.3-43.5), upper gastrointestinal tract endoscopy (PFS, 26.5-34.3), mastectomy (PFS, 16.5-35.0), inguinal hernia repair (PFS, 15.5-22.1), and abdominal wall hernia repair (PFS, 21.6-26.1). In all years, laparoscopic Roux-en-Y gastric bypass generated the highest number of wRVUs (wRVUs, 491.0-618.2), and laparoscopic cholecystectomy was regularly the next highest (wRVUs, 335.8-498.7). A significant proportion of academic general surgery is composed of bariatric surgery, yet surgical training does not sufficiently emphasize the necessary exposure to technical expertise

To describe the indications for and approaches to vitreoretinal surgery in patients with osteo-odonto-keratoprosthesis (OOKP). Retrospective case series. This was a retrospective review of all patients who had undergone OOKP surgery between 2003 and 2012 at our center. OOKP procedures were performed for severe ocular surface disease according to the indications and techniques described in the patient demographics of the Rome-Vienna Protocol. Indications for retinal surgery, surgical outcomes, and intraoperative and postoperative complications were documented. Operative techniques were reviewed from the surgical records, and any subsequent surgeries were also recorded. Thirty-six patients underwent OOKP, and retinal surgery was indicated in 13 (36%). The indications for and approaches to surgery were retinal detachment repair using an Eckardt temporary keratoprosthesis; assessment of retina and optic nerve health prior to OOKP surgery, using either a temporary keratoprosthesis or an endoscope; endoscopic cyclophotocoagulation for intractable glaucoma; endoscopic trimming of a retroprosthetic membrane; or vitrectomy for endophthalmitis with visualization through the OOKP optic using the binocular indirect viewing system. In all cases, retinal surgical aims were achieved with a single procedure. Postoperative vitreous hemorrhage occurred in 16 patients (44%), but all resolved spontaneously. OOKPs represent the last hope for restoration of vision in severe ocular surface disease, and the retinal surgeon is frequently called upon in the assessment and management of these patients. Temporary keratoprostheses and endoscopic vitrectomies are valuable surgical tools in these challenging cases, improving functional outcomes without compromising OOKP success.

The microflap technique is a standard procedure for the treatment of vocal fold polyps. Angiolytic laser surgery carried out under topical anesthesia is an alternative method for vocal polyp removal. However, it is not clear whether angiolytic laser surgery has the same effects on vocal outcomes as the microflap technique because of a lack of studies comparing both procedures. In the current study, vocal outcomes after both procedures were compared to clarify the effects of angiolytic laser surgery for vocal polyp removal. Vocal outcomes were reviewed for patients who underwent angiolytic laser surgery (n=20, laser group) or microflap surgery (n=34, microflap group) for vocal polyp removal. The data analyzed included patient and lesion characteristics, number of surgeries required for complete resolution, and aerodynamic and acoustic examinations before and after surgery. In the laser surgery group, complete resolution of the lesion was achieved with a single procedure in 17 cases (85%) and with two procedures in 3 cases (15%). Postoperative aerodynamic and acoustic parameters demonstrated significant improvement compared to preoperative parameters in both the laser surgery group and the microflap surgery group. There were no significant differences in any postoperative aerodynamic and acoustic parameters between the two groups. The current retrospective study demonstrated that angiolytic laser surgery achieved complete resolution of vocal polyps within two procedures. Postoperative effects on aerodynamic and acoustic functions were similar to those after microflap surgery. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Oncoplastic surgery is an evolving field in breast surgery combining the strengths of breast surgical oncology with plastic surgery. It provides the surgeon the ability to excise large areas of the breast in the oncologic resection without compromising, and possibly improving, its aesthetic appearance. The purpose of this review is to provide a guide that could help a breast surgeon excise breast cancer in most areas of the breast using 5 oncoplastic techniques. These techniques would be used depending primarily on the location of the cancer in the breast and also on the size of the tumor. PMID:28975837

Epidermolysis bullosa acquisita (EBA) is an uncommon, acquired, chronic subepidermal bullous disease. This report describes a case of EBA with gingival involvement. A 43-year-old woman with EBA was referred to our clinic for periodontal therapy because of gingival tenderness and bleeding. She has been on cyclosporin A therapy for the last 2 years. Clinical findings were analyzed. Anterior gingivectomy operations were performed in 2 stages. The samples obtained during the surgery were examined using histopathologic, immunohistologic, and electronmicroscopic methods. Long-term effects of the surgical periodontal treatment on gingiva were evaluated both clinically and microscopically. The dentition displayed minimal enamel hypoplasia. Decayed, missing, and filled surfaces score was found to be elevated. Periodontal examination showed generalized diffuse gingival inflammation and gingival enlargement localized mainly to the anterior region. Nikolsky's sign was positive. However, wound healing was uneventful after the operations. Microscopic findings were similar to those obtained from the skin. Twenty-one months after the operations, Nikolsky's sign was negative and no remarkable gingival inflammation was noted. Microscopic examination revealed that the blisters were fewer in number and smaller in size. These results indicate that gingival tissues may also be involved in EBA. Uneventful wound healing after periodontal surgery in this case suggests that periodontal surgery can be performed in patients with EBA. Moreover, both our clinical and histopathologic findings imply that gingivectomy proves useful in maintaining gingival integrity in these patients. Our data may also suggest that the patients with EBA are highly likely to develop dental caries.

Bariatric surgery makes up an increasing percentage of general surgery training. The safety of resident involvement in these complex cases has been questioned. We evaluated patient outcomes in resident performed laparoscopic bariatric procedures. Retrospective review of patients undergoing a laparoscopic bariatric procedure over seven years at a tertiary care single center. Procedures were primarily performed by a general surgery resident and proctored by an attending surgeon. Primary outcomes included operative volume, operative time and leak rate with perioperative outcomes evaluated as secondary outcomes. A total of 1649 bariatric procedures were evaluated. Operations included laparoscopic bypass (690) and laparoscopic sleeve gastrectomy (959). Average operating time was 136 min. Eighteen leaks (0.67%) were identified. Graduating residents performed an average of 89 laparoscopic bariatric cases during their training. There were no significant differences between resident levels with concern to operative time or leak rate (p 0.97 and p = 0.54). General surgery residents can safely perform laparoscopic bariatric surgery. When proctored by a staff surgeon, a resident's level of training does not significantly impact leak rate.

Epilepsy Surgery: An Evidence Summary

PubMed Central

2012-01-01

Background The Medical Advisory Secretariat, the predecessor of Health Quality Ontario, published an evidence-based analysis on functional brain imaging. This analysis highlighted the low uptake of epilepsy surgery in Ontario and internationally. Objective The objective of this analysis was to review the effectiveness of epilepsy surgery at reducing seizure frequency, as well as the safety of epilepsy surgery. Data Sources The literature search included studies published between January 1995 and March 2012. Search terms included epilepsy, surgery, resection, safety, and complications. Review Methods Studies were eligible for inclusion if they included at least 20 patients undergoing surgery; had a comparison group of patients with epilepsy who were not undergoing surgery; and reported follow-up periods of at least 1 year. Outcomes of interest included seizure frequency and complications associated with surgery. Results Six systematic reviews reported pooled seizure-free rates that ranged from 43% to 75%. Two randomized controlled trials compared the effectiveness of epilepsy surgery with no surgery in patients with drug-refractory epilepsy. Both trials reported significant improvements in the seizure frequency in the surgery group compared with the nonsurgery group. Eight retrospective cohort studies reported on the safety of epilepsy surgery. Of the 2,725 patients included in these studies, there were 3 deaths reportedly related to surgery. Other complications included hemiparesis, infection, and visual field defects. The studies had long follow-up periods ranging from a mean of 2 to 7 years. Limitations The most recent randomized controlled trial was stopped early due to slow enrolment rates. Thus results need to be interpreted with caution. Conclusions There is high quality evidence that epilepsy surgery is effective at reducing seizure frequency. Two randomized controlled trials compared surgery to no surgery in patients with drug-refractory epilepsy. Both

Purpose To present descriptive epidemiology of cataract surgery among Medicare recipients in the United States. Setting Cataract surgery performed on Medicare beneficiaries in 2003 and 2004. Methods Medicare claims data were used to identify all cataract surgery claims for procedures performed in the United States in 2003-2004. Standard assumptions were used to limit the claims to actual cataract surgery procedures performed. Summary statistics were created to determine the number of procedures performed for each outcome of interest: cataract surgery rates by age, race, and gender; surgical volume by facility type, surgeon characteristics, and state; time interval between first- and second-eye cataract surgery. Results The national cataract surgery rate for 2003-2004 was 61.8 per 1000 Medicare beneficiary person-years. The rate was significantly higher for females and for those 75-84. After adjustment for age and gender, blacks had approximately a 30% lower rate of surgery than whites. While only 5% of cataract surgeons performed more than 500 cataract surgeries annually, these surgeons performed 26% of the total cataract surgeries. Increasing surgical volume was found to be highly correlated with use of ambulatory surgical centers and reduced time interval between first- and second-eye surgery in the same patient. Conclusions The epidemiology of cataract surgery in the United States Medicare population documents substantial variation in surgical rates by race, gender, age, and by certain provider characteristics.

The national cataract surgery rate for 2003-2004 was 61.8 per 1000 Medicare beneficiary person-years. The rate was significantly higher for females and for those aged 75-84 years. After adjustment for age and sex, blacks had approximately a 30% lower rate of surgery than whites. While only 5% of cataract surgeons performed more than 500 cataract surgeries annually, these surgeons performed 26% of the total cataract surgeries. Increasing surgical volume was found to be highly correlated with use of ambulatory surgical centers and reduced time interval between first- and second-eye surgery in the same patient. The epidemiology of cataract surgery in the United States Medicare population documents substantial variation in surgical rates by race, sex, age, and by certain provider characteristics.

We present a rare case of a big oesophageal liposarcoma causing dysphagia and weight loss in a 75-year-old patient. Endoscopically, a pedunculated lesion with subtotal obstruction of the oesophageal lumen had been detected and thoracoabdominal oesophageal resection with gastric sleeve reconstruction was performed. Surprisingly, a liposarcoma of the oesophagus was revealed on histopathological analysis, showing MDM2 overexpression. Oncological follow-up has been uneventful and the patient remains in good clinical shape at 15 months after surgery.

Appendicectomy for acute appendicitis in children may be performed in specialist centres by paediatric surgeons or in general surgery units. Service provision and outcome of appendicectomy in children may differ between such units. This multicentre observational study included all children (aged less than 16 years) who had an appendicectomy at either a paediatric surgery unit or general surgery unit. The primary outcome was normal appendicectomy rate (NAR). Secondary outcomes included 30-day adverse events, use of ultrasound imaging and laparoscopy, and consultant involvement in procedures. Appendicectomies performed in 19 paediatric surgery units (242 children) and 54 general surgery units (461 children) were included. Children treated in paediatric surgery units were younger and more likely to have a preoperative ultrasound examination, a laparoscopic procedure, a consultant present at the procedure, and histologically advanced appendicitis than children treated in general surgery units. The unadjusted NAR was significantly lower in paediatric surgery units (odds ratio (OR) 0.37, 95 per cent confidence interval 0.23 to 0.59; P < 0.001), and the difference persisted after adjusting for age, sex and use of preoperative ultrasound imaging (OR 0.34, 0.21 to 0.57; P < 0.001). Female sex and preoperative ultrasonography, but not age, were significantly associated with normal appendicectomy in general surgery units but not in paediatric surgery units in this adjusted model. The unadjusted 30-day adverse event rate was higher in paediatric surgery units than in general surgery units (OR 1.90, 1.18 to 3.06; P = 0.011). When adjusted for case mix and consultant presence at surgery, no statistically significant relationship between centre type and 30-day adverse event rate existed (OR 1.59, 0.93 to 2.73; P = 0.091). The NAR in general surgery units was over twice that in paediatric surgery units. Despite a more severe case mix, paediatric surgery units had a

Enhanced Recovery After Surgery: The Plastic Surgery Paradigm Shift.

Bartlett, Erica L; Zavlin, Dmitry; Friedman, Jeffrey D; Abdollahi, Aariane; Rappaport, Norman H

2017-12-14

With a focus on providing high quality care and reducing facility based expenses there has been an evolution in perioperative care by way of enhanced recovery after surgery (ERAS). ERAS allows for a multidisciplinary and multimodal approach to perioperative care which not only expedites recovery but maximizes patient outcomes. This paradigm shift has been generally accepted by most surgical specialties, including plastic surgery. The goal of this study was to evaluate the impact of ERAS on outcomes in cosmetic plastic surgery. A prospective study consisting of phone call questionnaires was designed where patients from two senior plastic surgeons (N.H.R. and J.D.F.) were followed. The treatment group (n = 10) followed an ERAS protocol while the control group (n = 12) followed the traditional recovery after surgery which included narcotic usage. Patients were contacted on postoperative days (POD) 0 through 7+ and surveyed about a number of outcomes measures. The ERAS group demonstrated a significant reduction in postoperative pain on POD 0, 1, 2, and 3 (all P < 0.01). There was also statistically less nausea/vomiting, fatigue/drowsiness, constipation, and hindrance on ambulation compared to the control group (all P < 0.05). Significance was achieved for reduction in fatigue/drowsiness on POD 0 and 1 (P < 0.01), as well as ability to ambulate on POD 0 and 3 (P = 0.044). Lastly, opioid use (P < 0.001) and constipation (P = 0.003) were decreased. ERAS protocols have demonstrated their importance within multiple surgical fields, including cosmetic plastic surgery. The utility lies in the ability to expedite patient's recovery while still providing quality care. This study showed a reduction in postoperative complaints by avoiding narcotics without an increase in complications. Our findings signify the importance of ERAS protocols within cosmetic plastic surgery. 4. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Csorba, Roland

2012-06-24

Minimally invasive surgery has revolutionized gynecological interventions over the past 30 years. The introduction of the da Vinci robotic surgery in 2005 has resulted in large changes in surgical management. The robotic platform allows less experienced laparoscopic surgeons to perform more complex procedures. It can be utilized mainly in general gynecology and reproductive gynecology. The robot is being increasingly used for procedures such as hysterectomy, myomectomy, adnexal surgery, and tubal anastomosis. In urogynecology, the robot is being utilized for sacrocolopexy as well. In the field of gynecologic oncology, the robot is being increasingly used for hysterectomy and lymphadenectomy in oncologic diseases. Despite the rapid and widespread adaption of robotic surgery in gynecology, there are no randomized trials comparing its efficacy and safety to other traditional surgical approaches. This article presents the development, technical aspects and indications of robotic surgery in gynecology, based on the previously published reviews. Robotic surgery can be highly advantageous with the right amount of training, along with appropriate patient selection. Patients will have less blood loss, less post-operative pain, faster recovery, and fewer complications compared to open surgery and laparoscopy. However, until larger randomized control trials are completed which report long-term outcomes, robotic surgery cannot be stated to have priority over other surgical methods.

Pre-Surgery Psychological Factors Predict Pain, Nausea and Fatigue One Week Following Breast Cancer Surgery

PubMed Central

Montgomery, Guy H.; Schnur, Julie B.; Erblich, Joel; Diefenbach, Michael A.; Bovbjerg, Dana H.

Prior to scheduled surgery, breast cancer surgical patients frequently experience high levels of distress and expect a variety of post-surgery symptoms. Previous literature has supported the view that pre-surgery distress and response expectancies are predictive of post-surgery outcomes. However, the contributions of distress and response expectancies to post-surgical side effect outcomes have rarely been examined together within the same study. Furthermore, studies on the effects of response expectancies in the surgical setting have typically focused on the immediate post-surgical setting rather than the longer term. The purpose of the present study was to test the contribution of pre-surgery distress and response expectancies to common post-surgery side effects (pain, nausea, fatigue). Female patients (n=101) undergoing breast cancer surgery were recruited to a prospective study. Results indicated that pre-surgery distress uniquely contributed to patients’ post-surgery pain severity (P<0.05) and fatigue (P<0.003) one week following surgery. Response expectancies uniquely contributed to pain severity (P<0.001), nausea (P<0.012) and fatigue (P<0.010) one week following surgery. Sobel tests indicated that response expectancies partially mediated the effects of distress on pain severity (P<0.03) and fatigue (P<0.03). Response expectancies also mediated the effects of age on pain severity, nausea and fatigue. Results highlight the contribution of pre-surgery psychological factors to post-surgery side effects, the importance of including both emotional and cognitive factors within studies as predictors of post-surgery side effects, and suggest pre-surgical clinical targets for improving patients’ postoperative experiences of side effects.

Extrarenal Wilms' tumor of the ovary is a very rare tumor likely derived from embryonic mesonephros. We present the first reported case of a teratoid extrarenal Wilms' tumor of the ovary with a short review of the existing literature. In the case, a 26-year-old woman presented with back pain and was found to have a dermoid cyst; three years later, she presented again, now pregnant, with severe abdominal pain. She was diagnosed with an immature teratoma consisting of a Wilms' tumor (immature component) arising within a mature teratoma and treated exclusively with surgery and surveillance. The recovery from surgery was uneventful and the patient remains without evidence of disease with eleven months of follow-up.

Polyaxial screw head dislocation in the absence of a manufacture defect is extremely rare and represents a biomechanical overload of the screw, leading to early failure. A 58-year-old gentleman underwent instrumented fusion using polyaxial pedicle screws-titanium rod construct with interbody cage for spondylolytic spondylolisthesis at the L5/S1 level. He attempted to bend forward ten days after the surgery which resulted in a dislocation of the right S1 polyaxial screw head from the screw shank with recurrence of symptoms. He underwent revision surgery uneventfully. This case highlights the need to pay particular attention to the strength of fixation and the amount of release to avoid such a complication.

Postoperative intracranial epidural haematoma (EDH) is an extremely rare complication following spinal surgery, with only a handful of cases described in the literature. We report the case of a 16-year-old girl who underwent a successful subtotal resection of a giant lumbosacral schwannoma (L2-S2 level). Recovery from general anaesthesia was uneventful; however, her neurological status deteriorated rapidly within 24 h after surgery. A head computed tomography scan revealed a large right frontoparietal EDH with midline shift. An immediate frontotemporoparietal osteoplastic craniotomy and evacuation of the EDH were performed. At 1 year postoperatively, the patient regained full neurological recovery with no radiological signs of growth of the residual tumour. © 2017 S. Karger AG, Basel.

Global experiences in general surgery suggest that previous abdominal surgery may negatively influence different aspects of perioperative care. As the incidence of bariatric procedures has recently increased, it is essential to assess such correlations in bariatric surgery. To assess whether previous abdominal surgery influences the course and outcomes of laparoscopic bariatric surgery. Seven referral bariatric centers in Poland. We conducted a retrospective analysis of 2413 patients; 1706 patients who underwent laparoscopic sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) matched the inclusion criteria. Patients with no history of abdominal surgery were included as group 1, while those who had undergone at least 1 abdominal surgery were included as group 2. Group 2 had a significantly prolonged median operation time for RYGB (P = .012), and the longest operation time was observed in patients who had previously undergone surgeries in both the upper and lower abdomen (P = .002). Such a correlation was not found in SG cases (P = .396). Groups 1 and 2 had similar rates of intraoperative adverse events and postoperative complications (P = .562 and P = .466, respectively). Group 2 had a longer median duration of hospitalization than group 1 (P = .034), while the readmission rate was similar between groups (P = .079). There was no significant difference between groups regarding the influence of the long-term effects of bariatric treatment on weight loss (percentage of follow-up was 55%). Previous abdominal surgery prolongs the operative time of RYGB and the duration of postoperative hospitalization, but does not affect the long-term outcomes of bariatric treatment.

Timely access to orthopedic trauma surgery is essential for optimal outcomes. Regionalization of some types of surgery has shown positive effects on access, timeliness and outcomes. We investigated how the consolidation of orthopedic surgery in 1 Canadian health region affected patients requiring hip fracture surgery. We retrieved administrative data on all regional emergency department visits for lower-extremity injury and all linked inpatient stays from January 2010 through March 2013, identifying 1885 hip-fracture surgeries. Statistical process control and interrupted time series analysis controlling for demographics and comorbidities were used to assess impacts on access (receipt of surgery within 48-h benchmark) and surgical outcomes (complications, in-hospital/30-d mortality, length of stay). There was a significant increase in the proportion of patients receiving surgery within the benchmark. Complication rates did not change, but there appeared to be some decrease in mortality (significant at 6 mo). Length of stay increased at a hospital that experienced a major increase in patient volume, perhaps reflecting challenges associated with patient flow. Regionalization appeared to improve the timeliness of surgery and may have reduced mortality. The specific features of the present consolidation (including pre-existing interhospital performance variation and the introduction of daytime slates at the referral hospital) should be considered when interpreting the findings.

Aesthetic surgery and Google: ubiquitous, unregulated and enticing websites for patients considering cosmetic surgery.

Patient safety is a fundamental issue in aesthetic surgery. In an attempt to improve safety, the Department of Health (DoH) and Professor Sir Bruce Keogh published a review in 2013 of the regulation of cosmetic interventions. Proposals included: (1) Banning free consultations; (2) Restricting time-limited promotional deals; (3) Two-stage written pre-operative consent; (4) Consultations with a medical professional rather than a sales 'consultant'. The Cosmetic Surgical Practice Working Party (CSWP) recommended a two week "cooling off" period before surgery. This study quantified compliance with the above national initiatives by aesthetic surgery providers in the UK. To replicate a patient searching for aesthetic surgery providers, "cosmetic surgery UK" was searched via Google. The top fifty websites of aesthetic surgery providers were included in the study. Websites were analysed for compliance with the DoH Keogh and CSWP recommendations. When clarification was required, aesthetic surgery providers were contacted via telephone. Pearson's Chi-squared test compared actual compliance with national recommendations of full compliance. Fifty cosmetic surgery providers in the UK entered the study. Consultations with the operating surgeon occurred in 90% of cases. Mean compliance with all parameters from the national guidelines was 41%, significantly less than the desired level of full compliance (P < 0.001). The majority offered free consultations (54%) and promotional deals (52%), of which 27% were time limited. No provider stipulated compliance with two stages of signed consent. This study demonstrated low compliance with national guidelines for aesthetic surgery. Aggressive sales techniques and enticing offers by aesthetic surgery providers were widespread. Statutory government guidelines on aesthetic surgery and increased public awareness into potential risks from inappropriate cosmetic surgery may improve patient decision making and safety.

A 33-week pregnant (gravida 3), 29-year-old woman was transferred for management of Streptococcus sanguinis infective endocarditis. A vegetation was present on the posterior leaflet of the mitral valve with moderate mitral regurgitation. On admission (day 1), the ultrasound examination revealed splenic abscesses and retarded intrauterine growth albeit with normal vessels. The fetal heart rate was 140 bpm. On day 11, the baby was delivered by Caesarean, and then the mother underwent tubal ligation followed by a mitral valve repair. The splenic abscess was treated with antibiotics. The woman was clinically stable and recovered uneventfully. This successful outcome was achieved by a strategic (optimal and sequential) timeline for selecting the mode of delivery and type of mitral valve correction. PMID:24234426

To evaluate the importance and benefits of using gases in vitreoretinal surgery. The gases represent a wide group of substances used in eye surgery for more than 100 years. The role of intraocular gases in vitreoretinal surgery is irreplaceable. Their use is still considered to be the "gold standard". An important step in eye surgery was the introduction of expanding gases--sulfur hexafluoride and perfluorocarbons into routine clinical practice. The most common indications for the use of intraocular gases are: retinal detachment, idiopathic macular hole, complications of vitreoretinal surgery and others. The introduction of intraocular gases into routine clinical practice, along with other modern surgical techniques resulted in significant improvement of postoperative outcomes in a wide range of eye diseases. Understanding the principles of intraocular gases use brings the benefits to the patient and physician as well. Due to their physical and chemical properties they pose far the best and most appropriate variant of intraocular tamponade. Gases also bring some disadvantages, such as difficulties in detailed fundus examination, visual acuity testing, ultrasonographic examination, difficulties in application of intravitreal drugs or reduced possibility of retina laser treatment. The gases significantly change optical system properties of the eye. The use of gases in vitreoretinal surgery has significantly increased success rate of retinal detachment surgery, complicated posterior segment cases, trauma, surgery of the macula and other diseases.

Tuberculosis is mainly a medical disease. Surgery has been the unique therapeutic tool for a long time before the advent of specific antituberculous drugs, and the role of surgery was then confined to the treatment of the sequelae of tuberculosis and their complications. The resurgence of tuberculosis and the emergence of multidrug-resistant TB combined to immunosuppressed patients represent a new challenge for tuberculosis surgery. Surgery may be indicated for a diagnostic purpose in patients with pulmonary, pleural, mediastinal or thoracic wall involvement, or with a therapeutic purpose (drainage, resection, residual cavity obliteration). Modern imaging techniques and the advent of video-assisted thoracic surgery allowed a new approach of this pathology; the majority of diagnostic interventions and selected cases requiring lung resection can be performed through a mini-invasive approach. Patients proposed for aggressive surgery may be treated with the best results thanks to a good evaluation of the thoracic lesions, of the patients' nutritional, infectious and general status combined with a good coordination between the specialized medical team for an optimal preparation to surgery.

2014-01-01

The impact of bariatric surgery beyond its effect on weight loss has entailed a change in the way of regarding it. The term metabolic surgery has become more popular to designate those interventions that aim at resolving diseases that have been traditionally considered as of exclusive medical management, such as type 2 diabetes mellitus (T2D). Recommendations for metabolic surgery have been largely addressed and discussed in worldwide meetings, but no definitive consensus has been reached yet. Rates of diabetes remission after metabolic surgery have been one of the most debated hot topics, with heterogeneity being a current concern. This review aims to identify and clarify controversies regarding metabolic surgery, by focusing on a critical analysis of T2D remission rates achieved with different bariatric procedures, and using different criteria for its definition. Indications for metabolic surgery for patients with T2D who are not morbidly obese are also discussed. Copyright © 2013 SEEN. Published by Elsevier Espana. All rights reserved.

Laser-assisted cataract surgery versus standard ultrasound phacoemulsification cataract surgery.

Cataract is the leading cause of blindness in the world, and cataract surgery is one of the most commonly performed operations in the Western world. Preferred surgical techniques have changed dramatically over the past half century with associated improvements in outcomes and safety. Femtosecond laser platforms that can accurately and reproducibly perform key steps in cataract surgery, including corneal incisions, capsulotomy and lens fragmentation, are now available. The potential advantages of laser-assisted surgery are broad, and include greater safety and better visual outcomes through greater precision and reproducibility. To compare the effectiveness of laser-assisted cataract surgery with standard ultrasound phacoemulsification cataract surgery by gathering evidence on safety from randomised controlled trials (RCTs). We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 4), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to May 2016), EMBASE (January 1980 to May 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to May 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en) and the U.S. Food and Drugs Administration (FDA) website (www.fda.gov). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 10 May 2016. We included randomised controlled trials where laser-assisted cataract surgery was compared to standard ultrasound phacoemulsification cataract surgery. We graded the certainty of the evidence using GRADE. Two review authors independently screened the search results, assessed risk of bias and extracted data using the standard methodological

Robotic surgery is increasingly used to resect lung cancer. However costs are high. We compared costs and outcomes for robotic surgery, video-assisted thoracic surgery (VATS), and open surgery, to treat non-small cell lung cancer (NSCLC). We retrospectively assessed 103 consecutive patients given lobectomy or segmentectomy for clinical stage I or II NSCLC. Three surgeons could choose VATS or open, the fourth could choose between all three techniques. Between-group differences were assessed by Fisher's exact, two-way analysis of variance (ANOVA), and Wilcoxon-Mann-Whitney test. P values <0.05 were considered significant. Twenty-three patients were treated by robot, 41 by VATS, and 39 by open surgery. Age, physical status, pulmonary function, comorbidities, stage, and perioperative complications did not differ between the groups. Pathological tumor size was greater in the open than VATS and robotic groups (P=0.025). Duration of surgery was 150, 191 and 116 minutes, by robotic, VATS and open approaches, respectively (P<0.001). Significantly more lymph node stations were removed (P<0.001), and median length of stay was shorter (4, 5 and 6 days, respectively; P<0.001) in the robotic than VATS and open groups. Estimated costs were 82%, 68% and 69%, respectively, of the regional health service reimbursement for robotic, VATS and open approaches. Robotic surgery for early lung cancer was associated with shorter stay and more extensive lymph node dissection than VATS and open surgery. Duration of surgery was shorter for robotic than VATS. Although the cost of robotic thoracic surgery is high, the hospital makes a profit.

To analyze the spectrum of testicular tumors in prepubertal children and the therapeutic resultants in an unselected population. Our hospital database was analyzed for testicular tumors from January 1995 to December 2010 concerning clinical presentation, treatment and therapeutic results. Eight patients were operated on because of testicular tumors. In six cases (75%) the tumor was benign: benign teratoma (four cases), epidermoid cyst (one case) and immature teratoma (one case). Two patients (25%) had a malignant tumour: yolk-sac tumour (two cases). All this children underwent surgery. Radical inguinal orchidectomy was performed in six cases and conservative surgery was performed in two cases. One patient has received adjuvant chemotherapy. Follow-up was uneventfully three years after primary surgery. In prepubertal children, most testicular tumours are benign. If tumour markers were negative testis-preserving surgery can be proposed, complete excision of the tumour should be ascertained. In the case of testicular teratoma, the possibility of contralateral tumour should be considered in the follow-up.

1996-01-01

The importance of training centers can be best described after first answering a few questions like: 1. What kind of surgery will we deal with in the future? 2. What kind of surgeon do we need for this surgery, if it is basically different? 3. How will this surgeon have to be educated/trained for this different surgery? Although I am aware of the fact, that statements about future prospects are usually doomed to fail, I maintain that endoscopic surgery will be an essential part of general surgery. If this is so, surgery will be dominated by extremely complicated technology, new techniques and new instruments. It will be a "different" surgery. It will offer more comfort at the same safety. The surgeon of the future will still need a certain personality; he will still need intuition and creativity. To survive in our society, he will have to be an organiser and even a businessman. Additionally, something new has to be added: he will have to understand modern, complicated technology and will have to use totally different instruments for curing surgical illness. This makes it clear that we will need a different education/training and may be even a different selection of surgeons. We should learn from other professions sharing common interests with surgery, for example, sports where the common interest is achieving most complicated motions and necessarily highly differentiated coordination. Common interest with airline pilots is the target of achieving absolute security. They have a highly differentiated selection and training concept. Training centers may be-under certain prerequisites-a true alternative for this necessary form of training. They must have a concept, i.e. contents and aims have to be defined, structured and oriented on the requirements of surgery for the patient. Responsibility for the concept, performance and control can only be in the hands of Surgical Societies and Universities. These prerequisites correspond most likely to training centers being

Neuroendocrine carcinomas of the uterine cervix are rare, but extremely aggressive, gynecological malignancies that are associated with an overall poor prognosis. The present study reports the case of a 41-year-old patient diagnosed with large cell neuroendocrine cervical tumor. A radical total hysterectomy with bilateral adnexectomy, pelvic and lymph node dissection was performed. The post-operative course was uneventful, and the patient was discharged on post-operative day 8.

Aesthetic surgery is evolving rapidly, both technologically and conceptually. It is critical for the specialty that aesthetic surgery training keep pace with this rapid evolution. To shed more light on this issue, a survey was sent to all program directors and senior plastic surgery residents to record their impressions of the quality of cosmetic surgery resident training. The authors report the results of this national cosmetic surgery training survey canvassing all 89 plastic surgery programs. A three-page survey delineating resident preparedness in aesthetic surgery was sent to senior plastic surgery residents and program directors in April of 2006 and collected through October of 2006. Of 814 surveys, 292 responses were obtained from 64 percent of program directors and 33 percent of senior residents. Breast augmentation, breast reduction, and abdominoplasty were most frequently performed with the highest resident comfort levels. Rhinoplasty remained a particular area of trainee concern, but confidence levels were also low in face lifts, endoscopic procedures, and body contouring techniques. Experience with skin resurfacing, fillers, and botulinum toxin type A was another area of concern. Although 51 percent of residents felt prepared to integrate cosmetic surgery into their practices on graduation, 36 percent felt that further cosmetic training was desirable. The information collected revealed significant differences in opinions between program directors and senior residents. Senior residents felt deficient in facial cosmetic, minimally invasive, and recently developed body contouring techniques. On the basis of these results and the authors' experience in resident education, changes in cosmetic surgery training are suggested.

To examine the case mix and patient characteristics and outcomes of the nontrauma emergency (NTE) service in an academic Division of Acute Care Surgery. An NTE service (attending, chief resident, postgraduate year-3 and postgraduate year-2 residents, and two physician assistants) was created in July 2005 for all urgent and emergent inpatient and emergency department general surgery patient consults and admissions. An NTE database was created with prospective data collection of all NTE admissions initiated from November 1, 2007. Prospective data were collected by a dedicated trauma registrar and Acute Physiology and Chronic Health Evaluation-intensive care unit (ICU) coordinator daily. NTE case mix and ICU characteristics were reviewed for the 2-year time period January 1, 2008, through December 31, 2009. During the same time period, trauma operative cases and procedures were examined and compared with the NTE case mix. Thousand seven hundred eight patients were admitted to the NTE service during this time period (789 in 2008 and 910 in 2009). Surgical intervention was required in 70% of patients admitted to the NTE service. Exploratory laparotomy or laparoscopy was performed in 449 NTE patients, comprising 37% of all surgical procedures. In comparison, only 118 trauma patients (5.9% of admissions) required a major laparotomy or thoracotomy during the same time period. Acuity of illness of NTE patients was high, with a significant portion (13%) of NTE patients requiring ICU admission. NTE patients had higher admission Acute Physiology and Chronic Health Evaluation III scores [61.2 vs. 58.8 (2008); 58.2 vs. 55.8 (2009)], increased mortality [(9.71% vs. 4.89% (2008); 6.78% vs. 5.16% (2009)], and increased readmission rates (15.5% vs. 7.4%) compared with the total surgical ICU (SICU) admissions. In an era of declining operative caseload in trauma, the NTE service provides ample opportunity for complex general surgery decision making and operative procedures for

Background General surgery resident training has changed dramatically over the past 2 decades, with likely impact on specialty exposure. We sought to assess trends in general surgery resident exposure to thoracic surgery using the Accreditation Council for Graduate Medical Education (ACGME) case logs over time. Methods The ACGME case logs for graduating general surgery residents were reviewed from academic year (AY) 1989–1990 to 2011–2012 for defined thoracic surgery cases. Data were divided into 5 eras of training for comparison: I, AY89 to 93; II, AY93 to 98; III, AY98 to 03; IV, AY03 to 08; V, AY08 to 12. We analyzed quantity and types of cases per time period. Student t tests compared averages among the time periods with significance at a p values less than 0.05. Results A total of 21,803,843 general surgery cases were reviewed over the 23-year period. Residents averaged 33.6 thoracic cases each in period I and 39.7 in period V. Thoracic cases accounted for nearly 4% of total cases performed annually (period I 3.7% [134,550 of 3,598,574]; period V 4.1% [167,957 of 4,077,939]). For the 3 most frequently performed procedures there was a statistically significant increase in thoracoscopic approach from period II to period V. Conclusions General surgery trainees today have the same volume of thoracic surgery exposure as their counterparts over the last 2 decades. This maintenance in caseload has occurred in spite of work-hour restrictions. However, general surgery graduates have a different thoracic surgery skill set at the end of their training, due to the predominance of minimally invasive techniques. Thoracic surgery educators should take into account these differences when training future cardiothoracic surgeons. PMID:24968766

The advancement of surgical technology has made surgery an increasingly suitable management option for an increasing number of medical conditions. Yet there is also a growing concern about the number of patients coming to harm as a result of surgery. Studies show that this harm can be prevented by better teamwork and communication in operating theatres. This article discusses the extent of adverse events in surgery and how effective teamwork and communication can improve patient safety. It also highlights the role checklists and briefing in improving teamwork and reducing human error in surgery.

Hyperoxaluria and Bariatric Surgery

NASA Astrophysics Data System (ADS)

Asplin, John R.

2007-04-01

Bariatric surgery as a means to treat obesity is becoming increasingly common in the United States. An early form of bariatric surgery, the jejunoileal bypass, had to be abandoned in 1980 due to numerous complications, including hyperoxaluria and kidney stones. Current bariatric procedures have not been systematically evaluated to determine if they cause hyperoxaluria. Presented here are data showing that hyperoxaluria is the major metabolic abnormality in patients with bariatric surgery who form kidney stones. Further studies are needed to assess the prevalence of hyperoxaluria in all patients with bariatric surgery.

We report a 66-yr-old male patient who developed tricuspid regurgitation secondary to internal cardiac massage. After uneventful off-pump coronary artery bypass surgery, the subject experienced cardiac arrest in the intensive care unit. External cardiac massage was initiated and internal cardiac massage was performed eventually. A transesophageal echocardiography revealed avulsion of the anterior papillary muscle and chordae to the anterior leaflet after successful cardiopulmonary resuscitation. Emergency repair of the papillary muscle was performed under cardiopulmonary bypass. PMID:17728519

We present a rare case of left ventricular myxoma discovered incidentally in an asymptomatic 16-year old male. The patient underwent the appropriate work-up and a robotic-assisted excision of the mass. The patient had an uneventful recovery and was discharged home at postoperative day 3. To our knowledge, this is the first case of robotic-assisted left ventricular myxoma excision in the literature. Robotic-assisted surgery of left ventricular myxomas is a safe and feasible method of excision.

An infant with craniosynostosis for craniectomy and cranial-vault remodelling was detected to have very low hemoglobin (6.8 gm%) after induction of anesthesia. This posed a dilemma whether to proceed with or abandon the surgical procedure. The case was postponed and was rescheduled for surgery one week later with hope that his hemoglobin would rise during this period. However, even before second anesthesia his hemoglobin level was found to be unchanged. Meticulous anesthesia management resulted in uneventful surgical procedure. PMID:25885398

Current Status of Laparoendoscopic Single-Site Surgery in Urologic Surgery

PubMed Central

2012-01-01

Since the introduction of laparoscopic surgery, the promise of lower postoperative morbidity and improved cosmesis has been achieved. Laparoendoscopic single-site surgery (LESS) potentially takes this further. Following the first human urological LESS report in 2007, numerous case series have emerged, as well as comparative studies comparing LESS with standard laparoscopy. However, comparative series between conventional laparoscopy and LESS for different procedures suggest a non-inferiority of LESS over standard laparoscopy, but the only objective benefit remains an improved cosmetic outcome. Challenging ergonomics, instrument clashing, lack of true triangulation, and in-line vision are the main concerns with LESS surgery. Various new instruments have been designed, but only experienced laparoscopists and well-selected patients are pivotal for a successful LESS procedure. Robotic-assisted LESS procedures have been performed. The available robotic platform remains bulky, but development of instrumentation and application of robotic technology are expected to define the actual role of these techniques in minimally invasive urologic surgery.

Smoking is a cause of cancer and polycythemia. Therefore, surgeons who treat patients with cancer may also encounter patients with polycythemia. However, few cases of surgical patients with polycythemia have been reported; in particular, a surgical case involving smokers' polycythemia has never been reported. We herein report a patient with lung cancer and smokers' polycythemia who successfully underwent lobectomy with control of hematocrit based on a modified formula in the perioperative period. A 67-year-old man underwent abdominoperineal resection for rectal carcinoma in June 2008. A ground glass opacity had been identified in the upper lobe of the right lung and was gradually enlarging. In March 2012, bronchoscopic cytology for investigation of the mass revealed non-small cell lung cancer, suggesting primary lung non-small cell carcinoma (T1bN0M0, Stage IA). When he was referred to our hospital for surgery, his complete blood count showed a red blood cell level of 6.50×106/μL, hemoglobin of 21.0 g/dL, and hematocrit of 60.1%. The hematologists' diagnosis was secondary polycythemia due to heavy smoking (smokers' polycythemia) because the white blood cell and platelet counts were within normal limits and the erythropoietin was not increased. We calculated the appropriate phlebotomy and infusion volumes based on a formula that we modified. After 550 g of blood was phlebotomized to reduce the hematocrit to approximately 55%, video-assisted right lung upper lobectomy with lymph node dissection was performed in April 2012. The hematocrit was maintained at <50% postoperatively, and the patient was uneventfully discharged on postoperative day 7. The predictive hematocrit and measured hematocrit were very closely approximated in this case. We experienced a patient with smokers' polycythemia who underwent right upper lobectomy for adenocarcinoma. The findings in this case report are meaningful for surgeons treating cancer patients because there are few reports

Crohn's disease is a chronic inflammatory bowel disease characterized by uncertainty in etiology and pathogenesis occasionally with manifestations in oral mucous membranes. This report reviews the literature on Crohn's disease and presents a patient with Crohn's disease on continuous anti-inflammatory and immunosuppressive medication who showed adverse healing response following surgical treatment of gingival recession type defects. A 28-year-old male in generally good health apart from his bowel disease requested treatment of multiple maxillary gingival recessions due to esthetic concerns and root sensitivity. Following oral hygiene instruction, 3 coronally advanced flap procedures were performed in the maxillary anterior region to cover the defects. In 2 of the surgical areas, the exposed root surfaces were treated by ethylenediaminetetraacetic acid (EDTA) in combination with enamel matrix derivative (EMD) before coronally positioning the buccal flap. Postoperatively, chlorhexidine gluconate was used for oral hygiene control. The first surgical procedure, performed as a coronally advanced flap, showed delayed and altered healing. Two weeks postoperatively, the flapped tissue remained intensely red and swollen. In the following 2 surgical sites where EDTA and EMD were applied the healing was uneventful. Differences in immediate tissue response, however, did not influence the 3-month treatment outcome with respect to root coverage. Patients with Crohn's disease on recommended systemic medications may show a delayed and altered wound healing indicating that periodontal surgery must be closely monitored. Treatment planning should take into account the potential wound healing promoting effects of enamel matrix derivative as well as adverse healing effects of chlorhexidine gluconate administration.

The development of imaging modalities and computer technology provides a new approach in acetabular surgery. Areas covered: This review describes the role of computer-assisted surgery (CAS) in understanding of the fracture patterns, in the virtual preoperative planning of the surgery and in the use of custom-made plates in acetabular fractures with or without 3D printing technologies. A Pubmed internet research of the English literature of the last 20 years was carried out about studies concerning computer-assisted surgery in acetabular fractures. The several steps for CAS in acetabular fracture surgery are presented and commented by the main author regarding to his personal experience. Expert commentary: Computer-assisted surgery in acetabular fractures is still initial experiences with promising results. Patient-specific biomechanical models considering soft tissues should be developed to allow a more realistic planning.

Robotic systems are increasingly being incorporated into general laparoscopic and thoracoscopic surgery to perform procedures such as cholecystectomy and prostatectomy. Robotic assisted surgery allows the surgeon to conduct minimally invasive surgery with increased accuracy and with potential benefits for patients. However, current robotic systems have their limitations. These include the narrow operative field of view, which can make instrument manipulation difficult. Current robotic applications are also tailored to specific surgical procedures. For these reasons, there is an increasing demand on surgeons to master the skills of instrument manipulation and their surgical application within a controlled environment. This study describes the development of a surgical simulator for training and mastering procedures performed with the da Vinci surgical system. The development of a tele-surgery simulator and the construction of a training center are also described, which will enable surgeons to simulate surgery from or in remote places, to collaborate over long distances, and for off-site expert assistance.

Does procedure profitability impact whether an outpatient surgery is performed at an ambulatory surgery center or hospital?

PubMed

Plotzke, Michael Robert; Courtemanche, Charles

2011-07-01

Ambulatory surgery centers (ASCs) are small (typically physician owned) healthcare facilities that specialize in performing outpatient surgeries and therefore compete against hospitals for patients. Physicians who own ASCs could treat their most profitable patients at their ASCs and less profitable patients at hospitals. This paper asks if the profitability of an outpatient surgery impacts where a physician performs the surgery. Using a sample of Medicare patients from the National Survey of Ambulatory Surgery, we find that higher profit surgeries do have a higher probability of being performed at an ASC compared to a hospital. After controlling for surgery type, a 10% increase in a surgery's profitability is associated with a 1.2 to 1.4 percentage point increase in the probability the surgery is performed at an ASC.

2015-03-01

After approval by the Thoracic Surgery Residency Review Committee in 2007, 6-year integrated cardiothoracic surgery (I-6) residency programs have gained in popularity. We sought to assess and objectively quantify the level of satisfaction I-6 residents have with their training and to identify areas of improvement for future curriculum development. A completely anonymous, electronic survey was created by the Thoracic Surgery Residents Association that asked the responders to provide demographic information, specialty interest, and lifestyle priorities, and to rate their experience and satisfaction with I-6 residency. The survey was distributed nationwide to all residents in I-6 programs approved by the Accreditation Council for Graduate Medical Education. Of a total of 88 eligible I-6 residents, 49 completed the survey (55.7%). Career choice satisfaction was high (75.5%), as was overall satisfaction with integrated training (83.7%). The majority (77.6%) were interested in cardiac surgery. Overall, the responders reported sufficient time for life outside of the hospital (57.1%), but experienced conflicts between work obligations and personal life at least sometimes (75.5%). Early exposure to cardiothoracic surgery was reported as the dominant advantage of the I-6 model, whereas variable curriculum structure and unclear expectations along with poor integration with general surgery training ranked highest among perceived disadvantages. Current I-6 residents are largely satisfied with the integrated training model and report a reasonable work/life balance. The focused nature of training is the primary perceived advantage of the integrated pathway. Curriculum variability and poor integration with general surgery training are identified by residents as primary areas of concern. Copyright © 2015 The Society of Thoracic Surgeons.

2016-06-01

Applicants for craniofacial surgery fellowships utilize Internet-based resources like the San Francisco (SF) Match to manage applications. The purpose of this study was to evaluate the accessibility and content of craniofacial surgery fellowship websites (CSFWs). A list of available craniofacial surgery fellowships was compiled from directories of the American Society of Craniofacial Surgery (ACSFS) and SF Match. Accessibility of CSFWs was assessed via links from these directories and a Google search. Craniofacial surgery fellowship websites were evaluated on education and recruitment content and compared via program characteristics. Twenty-four of the 28 US-based craniofacial surgery fellowship programs had a CSFW (86%). The ACSFS and SF Match databases had limited CSFW accessibility, but a Google search revealed most CSFWs had the top search result (76%). In total, CSFWs provided an average of 39% of education and recruitment variables. While most programs provided fellowship program descriptions (96%), application links (96%), and faculty listings (83%), relatively few provided rotation schedules (13%), fellow selection process information (13%), or interview dates (8%). CSFW content did not vary by program location, faculty size, accreditation status, or institutional affiliations (P > 0.05). Craniofacial surgery fellowships often lack readily accessible websites from national program lists and have limited information for interested applicants. The consistent lack of online information across programs suggests future opportunities exist to improve these educational resources.

Laparoscopic surgery complications: postoperative peritonitis.

2012-09-15

Complications within laparoscopic surgery, similar to classic surgery are inevitable and require immediate actions both to diminish intraoperative risks and to choose the appropriate therapeutic attitude. Peritonitis and hemorrhagic incidents are both part of the complications aspect of laparoscopic surgery. Fortunately, the incidence is limited, thus excluding the rejection of celioscopic methods. Patient's risks and benefits are to be analyzed carefully prior recommending laparoscopic surgery. This study presents a statistical analysis of peritonitis consecutive to laparoscopic surgery, experience of "Sf. Ioan" Emergency Hospital, Bucharest, and Department of Surgery (2000-2010). There were 180 (0,96%) complicated situations requiring reinterventions, from a total of 18676 laparoscopic procedures. 106 cases (0,56%) represented different grades of postoperative peritonitis. Most frequently, there were consecutive laparoscopic appendicectomia and colecistectomia. During the last decade, few severe cases of peritonitis followed laparoscopic bariatric surgical procedures. This study reflects the possibility of unfavorable evolution of postoperative peritonitis comparing with hemorrhagic incidents within laparoscopic surgery.

Additive Effect of Oral Steroid with Topical Nonsteroidal Anti-inflammatory Drug for Preventing Cystoid Macular Edema after Cataract Surgery in Patients with Epiretinal Membrane

Purpose To investigate the additive effect of oral steroid with topical nonsteroidal anti-inflammatory drug (NSAID) on cystoid macular edema (CME) in patients with epiretinal membrane (ERM) after cataract surgery. Methods Medical records of subjects who underwent uneventful cataract surgery (n = 1,349) were retrospectively reviewed; among these patients, those with pre-existing ERM (n = 81) were included. Patients were divided into two groups: one group had postoperative administration of oral steroid for 1 week (n = 45) and the other group did not have oral steroid administration (n = 36). Changes in macular thickness and incidence of CME were compared in both groups. Topical NSAIDs were administered in both groups for 1 month postoperatively. Definite CME and probable CME were defined by changes in retinal contour with or without cystoid changes. Change in central macular thickness of more than three standard deviations (≥90.17 µm) was defined as possible CME. Macular thickness was measured at 1 month after the operation by optical coherence tomography. Results The incidence of definite, probable, and possible CME were 2.22%, 4.44%, and 8.89% with the use of steroid and 2.78%, 5.56%, and 8.33% without steroid, respectively (p = 0.694, p = 0.603, and p = 0.625), and regardless of treatment group, the incidences in these patients were higher compared to incidences in whole subjects (1.26%, 2.30%, and 4.32%; p = 0.048, p = 0.032, and p = 0.038, respectively). The differences in macular thickness were not statistically different between the two groups. Average changes of central foveal thickness in 3 mm and 6 mm zone were 29.29 µm, 35.93 µm, and 38.02 µm with the use of steroid and 32.25 µm, 44.08 µm, and 45.39 µm without steroid (p = 0.747, p = 0.148, and p = 0.077, respectively). Conclusions This study suggests that administration of oral steroid may not have a synergistic effect in reduction of CME and retinal thickness in patients with pre-existing ERM

Robotic surgery has been proposed as a minimally invasive surgical technique with advantages for both surgeons and patients, but is associated with high costs (installation, use and maintenance). The Health Technology Assessment Unit of the Bambino Gesù Children's Hospital sought to investigate the economic sustainability of robotic surgery, having foreseen its impact on the hospital budget METHODS: Break-even and cost-minimization analyses were performed. A deterministic approach for sensitivity analysis was applied by varying the values of parameters between pre-defined ranges in different scenarios to see how the outcomes might differ. The break-even analysis indicated that at least 349 annual interventions would need to be carried out to reach the break-even point. The cost-minimization analysis showed that robotic surgery was the most expensive procedure among the considered alternatives (in terms of the contribution margin). Robotic surgery is a good clinical alternative to laparoscopic and open surgery (for many pediatric operations). However, the costs of robotic procedures are higher than the equivalent laparoscopic and open surgical interventions. Therefore, in the short run, these findings do not seem to support the decision to introduce a robotic system in our hospital.

Orthognathic surgery is this field of the maxillofacial surgery which aims to reposition the jaws or some segments of these jaws when masticatory dysfunctions are evident. This tridimensional repositioning in the craniofacial skeleton allows to restore the masticatory function by means of osteotomies, which must be followed either by preoperative simulated bony displacements or by callus bone distraction. Not only are the functional benefits evident on the dental, articular and neuromuscular levels, but also a facial esthetic harmony can almost be obtained.

Surgery has played an essential role in the treatment of Crohn's disease. Emergency can reveal previously unknown complications whose treatment affects prognosis. Indicate the incidence of indications in emergent surgery for Crohn's disease. Specify the types of procedures performed in these cases and assess the Results of emergency surgery for Crohn's disease postoperatively,  in short , medium and long term. Retrospective analysis of collected data of 38 patients, who underwent surgical resection for Crohn's disease during a period of 19 years from 1992 to 2011 at the department of surgery in MONGI SLIM Hospital, and among them 17 patients underwent emergency surgery for Crohn's disease. In addition to socio-demographic characteristics and clinical presentations of our study population, we evaluated the indications, the type of intervention, duration of evolution preoperative and postoperative complications and overall prognosis of the disease. Of the 38 patients with Crohn's disease requiring surgical intervention, 17/38 patients underwent emergency surgery. Crohn's disease was inaugurated by the complications requiring emergency surgery in 11 patients. The mean duration of symptoms prior to surgery was 1.5 year. The most common indication for emergency surgery was acute intestinal obstruction (n=6) followed by perforation and peritonitis (n=5). A misdiagnosis of appendicitis was found in 4 patients and a complicated severe acute colitis for undiagnosed Crohn's disease was found in 2 cases. The open conventional surgery was performed for 15 patients. Ileocolic resection was the most used intervention. There was one perioperative mortality and 5 postoperative morbidities. The mean of postoperative hospital stay was 14 days (range 4-60 days). Six patients required a second operation during the follow-up period. The incidence of emergency surgery for Crohn's disease in our experience was high (17/38 patients), and is not as rare as the published estimates

Evidence-Based Medicine in Aesthetic Surgery: The Significance of Level to Aesthetic Surgery.

Since its popularization in the 1980s, evidence-based medicine has become the cornerstone of American health care. Many specialties rapidly adapted to the paradigm shift of health care by delivering treatment using the evidence-based guidelines. However, the field of plastic surgery has been slow to implement evidence-based medicine compared with the other specialties because of the challenges of performing randomized controlled trials, such as funding, variability in surgical skills, and difficulty with standardization of techniques. To date, aesthetic surgery has been at the forefront of evidence-based medicine in plastic surgery by having the most randomized controlled trials. Nevertheless, a detailed analysis of these studies has not been previously performed. In this article, the level I and II articles of aesthetic surgery are discussed to increase awareness of high-quality evidence-based medicine in aesthetic surgery.

Development and implementation of a formalized geriatric surgery curriculum for general surgery residents.

Despite the growth of the elderly population, most surgical training programs lack formalized geriatric education. The authors' aim was to implement a formalized geriatric surgery curriculum at an academic medical center. Surgery residents were surveyed on attitudes toward the care of elderly patients and the importance of various geriatric topics to daily practice. A curriculum consisting of 16 didactic sessions was created with faculty experts moderating. After curriculum completion, residents were surveyed to assess curriculum impact. Residents expressed increased comfort in accessing community resources. A greater percentage of residents recognized the significance of delirium and acute renal failure in elderly patients. Implementing a geriatric surgery curriculum geared toward surgery residents is feasible and can increase resident comfort with multidisciplinary care and recognition of clinical conditions pertinent to elderly surgical patients. This initiative also provided valuable experience for geriatric surgery curriculum development.

Forward surgery.

Deployment of Forward Surgery is a balance of risk and benefit. The resources will clearly be less than at a more major facility and so care may be compromised. Equally the tactical situation may be non-permissive and limb and life saving intervention required before the movement is possible. However, in order to provide satisfactory care at a forward location sufficient resources to deliver the full requirements of DCR & DCS must be met, which would limit manoeuvrability. This would include large volumes of blood and blood products, critical care and experienced personnel. The later will need to be some of the most senior medical staff as the decision to not operate, if intervention is unnecessary as the patient could wait or intervention would be futile, is one that requires experience. The deployment of these personnel would need to be balanced with the depletion of the experience from the major facility. Forward surgery may be appropriate in the build up phase, establishing a first surgical foot print to develop into a more capable facility (26) or wind down as the major facility is dismantled to be relocated at an alternative location. Ultimately the deployment of forward surgery hinges on the tactical assessment and the ability to evacuate casualties in a timely fashion to the best equipped and resourced facility possible. This decision must be informed by the limitations this may impose on the management of the majority casualties who do not require forward surgery. Forward surgery should only be deployed as part of an overall trauma system with continuous assessment of outcomes. The goal remains "the right patient, right place at the right time".

Robotic surgery - advance or gimmick?

PubMed

De Wilde, Rudy L; Herrmann, Anja

2013-06-01

Robotic surgery is increasingly implemented as a minimally invasive approach to a variety of gynaecological procedures. The use of conventional laparoscopy by a broad range of surgeons, especially in complex procedures, is hampered by several drawbacks. Robotic surgery was created with the aim of overcoming some of the limitations. Although robotic surgery has many advantages, it is also associated with clear disadvantages. At present, the proof of superiority over access by laparotomy or laparoscopy through large randomised- controlled trials is still lacking. Until results of such trials are present, a firm conclusion about the usefulness of robotic surgery cannot be drawn. Robotic surgery is promising, making the advantages of minimally invasive surgery potentially available to a large number of surgeons and patients in the future. Copyright © 2013 Elsevier Ltd.

Completely staple-free hand-sewn laparoscopic anastomosis in colorectal surgery.

PubMed

Lipski, David; Dapri, Giovanni; Himpens, Jacques

2008-04-01

Colonic continuity following a laparoscopic left hemicolectomy is usually performed by using a circular stapler to achieve end-to-end colorectal anastomosis. However, not much consideration is given to the costs of this technique and the long-term risk of stenosis. In this paper, we report the first case of a completely staple-free hand-sewn laparoscopic colonic anastomosis (CSHLCA) following a laparoscopic left hemicolectomy for cancer. Total operative time was 170 minutes, and the time to perform the anastomosis was 38 minutes. The postoperative stay was uneventful, with a total hospital stay of 6 days. CSHLCA is feasible and can lower the cost of the laparoscopic procedure. It may be considered in countries with limited access to mechanical staplers.

A perverse quality incentive in surgery: implications of reimbursing surgeons less for doing laparoscopic surgery.

Fader, Amanda N; Xu, Tim; Dunkin, Brian J; Makary, Martin A

Surgery is one of the highest priced services in health care, and complications from surgery can be serious and costly. Recently, advances in surgical techniques have allowed surgeons to perform many common operations using minimally invasive methods that result in fewer complications. Despite this, the rates of open surgery remain high across multiple surgical disciplines. This is an expert commentary and review of the contemporary literature regarding minimally invasive surgery practices nationwide, the benefits of less invasive approaches, and how minimally invasive compared with open procedures are differentially reimbursed in the United States. We explore the incentive of the current surgeon reimbursement fee schedule and its potential implications. A surgeon's preference to perform minimally invasive compared with open surgery remains highly variable in the U.S., even after adjustment for patient comorbidities and surgical complexity. Nationwide administrative claims data across several surgical disciplines demonstrates that minimally invasive surgery utilization in place of open surgery is associated with reduced adverse events and cost savings. Reducing surgical complications by increasing adoption of minimally invasive operations has significant cost implications for health care. However, current U.S. payment structures may perversely incentivize open surgery and financially reward physicians who do not necessarily embrace newer or best minimally invasive surgery practices. Utilization of minimally invasive surgery varies considerably in the U.S., representing one of the greatest disparities in health care. Existing physician payment models must translate the growing body of research in surgical care into physician-level rewards for quality, including choice of operation. Promoting safe surgery should be an important component of a strong, value-based healthcare system. Resolving the potentially perverse incentives in paying for surgical approaches may

Fast-track surgery after gynaecological oncological surgery: study protocol for a prospective randomised controlled trial.

PubMed

Cui, Ling; Shi, Yu; Zhang, G N

2016-12-15

Fast-track surgery (FTS), also known as enhanced recovery after surgery, is a multidisciplinary approach to accelerate recovery, reduce complications, minimise hospital stay without increasing readmission rates, and reduce health care costs, all without compromising patient safety. The advantages of FTS in abdominal surgery most likely extend to gynaecological surgery, but this is an assumption, as FTS in elective gynaecological surgery has not been well studied. No consensus guidelines have been developed for gynaecological oncological surgery although surgeons have attempted to introduce slightly modified FTS programmes for patients undergoing such surgery. To our knowledge, there are no published randomised controlled trials; however, some studies have shown that FTS in gynaecological oncological surgery leads to early hospital discharge with high levels of patient satisfaction. The aim of this study is whether FTS reduces the length of stay in hospital compared to traditional management. The secondary aim is whether FTS is associated with any increase in post-surgical complications compared to traditional management (for both open and laparoscopic surgery). This trial will prospectively compare FTS and traditional management protocols. The primary endpoint is the length of post-operative hospitalisation (days, mean ± standard deviation), defined as the number of days between the date of discharge and the date of surgery. The secondary endpoints are complications in both groups (FTS versus traditional protocol) occurring during the first 3 months post-operatively including infection (wound infection, lung infection, intraperitoneal infection), post-operative nausea and vomiting, ileus, post-operative haemorrhage, post-operative thrombosis, and the Acute Physiology and Chronic Health Enquiry II score. The advantages of FTS most likely extend to gynaecology, although, to our knowledge, there are no randomised controlled trials. The aim of this study is to

The surgery during which the cochlear implant internal device is implanted is not entirely free of risks and may produce problems that will require revision surgeries. To verify the indications for cochlear implantation revision surgery for the cochlear implant internal device, its effectiveness and its correlation with certain variables related to language and hearing. A retrospective study of patients under 18 years submitted to cochlear implant Surgery from 2004 to 2015 in a public hospital in Brazil. Data collected were: age at the time of implantation, gender, etiology of the hearing loss, audiological and oral language characteristics of each patient before and after Cochlear Implant surgery and any need for surgical revision and the reason for it. Two hundred and sixty-five surgeries were performed in 236 patients. Eight patients received a bilateral cochlear implant and 10 patients required revision surgery. Thirty-two surgeries were necessary for these 10 children (1 bilateral cochlear implant), of which 21 were revision surgeries. In 2 children, cochlear implant removal was necessary, without reimplantation, one with cochlear malformation due to incomplete partition type I and another due to trauma. With respect to the cause for revision surgery, of the 8 children who were successfully reimplanted, four had cochlear calcification following meningitis, one followed trauma, one exhibited a facial nerve malformation, one experienced a failure of the cochlear implant internal device and one revision surgery was necessary because the electrode was twisted. The incidence of the cochlear implant revision surgery was 4.23%. The period following the revision surgeries revealed an improvement in the subject's hearing and language performance, indicating that these surgeries are valid in most cases.

2014-07-01

Tricuspid valve insufficiency (TI) following cardiovascular surgery causes right-side heart failure and hepatic failure, which affect patient prognosis. Moreover, the benefits of reoperation for severe tricuspid insufficiency remain unclear. We investigated the surgical outcomes of reoperation in TI. From the Japan Cardiovascular Surgery Database (JACVSD), we extracted cases who underwent surgery for TI following cardiac surgery between January 2006 and December 2011. We analysed the surgical outcomes, specifically comparing tricuspid valve replacement (TVR) and tricuspid valve plasty (TVP). Of the 167 722 surgical JACVSD registered cases, reoperative TI surgery occurred in 1771 cases, with 193 TVR cases and 1578 TVP cases. The age and sex distribution was 684 males and 1087 females, with an average age of 66.5 ± 10.8 years. The overall hospital mortality was 6.8% and was significantly higher in the TVR group than in the TVP group (14.5 vs 5.8%, respectively; P < 0.001). Incidences of dialysis, prolonged ventilation and heart block were also significantly higher in the TVR group than in the TVP group. Logistic regression analysis revealed that the risk factors of hospital mortality were older age, preoperative renal dysfunction, preoperative New York Heart Association Class 4, left ventricular dysfunction and TVR. Surgical outcomes following reoperative tricuspid surgery were unsatisfactory. Although TVR is a last resort for non-repairable tricuspid lesions, it carries a significant risk of surgical mortality. Improving the patient's preoperative status and opting for TVP over TVR is necessary to improve the results of reoperative tricuspid surgery. © The Author 2014.

2014-01-01

Background: Massive weight loss (MWL) following bariatric surgery frequently results in an excess of overstretched skin causing physical discomfort and negatively affecting quality of life, self-esteem, body image, and physical functioning. Methods: In this cross-sectional study 3 groups were compared: (1) patients prior to bariatric surgery (n = 79), (2) patients after bariatric surgery who had not undergone body contouring surgery (BCS) (n = 252), and (3) patients after bariatric surgery who underwent subsequent BCS (n = 62). All participants completed self-report questionnaires assessing body image (Multidimensional Body-Self Relations Questionnaire, MBSRQ), quality of life (IWQOL-Lite), symptoms of depression (PHQ-9), and anxiety (GAD-7). Results: Overall, 62 patients (19.2%) reported having undergone a total of 90 BCS procedures. The most common were abdominoplasties (88.7%), thigh lifts (24.2%), and breast lifts (16.1%). Post-bariatric surgery patients differed significantly in most variables from pre-bariatric surgery patients. Although there were fewer differences between patients with and without BCS, patients after BCS reported better appearance evaluation (AE), body area satisfaction (BAS), and physical functioning, even after controlling for excess weight loss and time since surgery. No differences were found for symptoms of depression and anxiety, and most other quality of life and body image domains. Discussion: Our results support the results of longitudinal studies demonstrating significant improvements in different aspects of body image, quality of life, and general psychopathology after bariatric surgery. Also, we found better AE and physical functioning in patients after BCS following bariatric surgery compared to patients with MWL after bariatric surgery who did not undergo BCS. Overall, there appears to be an effect of BCS on certain aspects of body image and quality of life but not on psychological aspects on the whole. PMID:25477839

Trigger finger is a common clinical disorder, characterised by pain and catching as the patient flexes and extends digits because of disproportion between the diameter of flexor tendons and the A1 pulley. The treatment approach may include non-surgical or surgical treatments. Currently there is no consensus about the best surgical treatment approach (open, percutaneous or endoscopic approaches). To evaluate the effectiveness and safety of different methods of surgical treatment for trigger finger (open, percutaneous or endoscopic approaches) in adults at any stage of the disease. We searched CENTRAL, MEDLINE, Embase and LILACS up to August 2017. We included randomised or quasi-randomised controlled trials that assessed adults with trigger finger and compared any type of surgical treatment with each other or with any other non-surgical intervention. The major outcomes were the resolution of trigger finger, pain, hand function, participant-reported treatment success or satisfaction, recurrence of triggering, adverse events and neurovascular injury. Two review authors independently selected the trial reports, extracted the data and assessed the risk of bias. Measures of treatment effect for dichotomous outcomes calculated risk ratios (RRs), and mean differences (MDs) or standardised mean differences (SMD) for continuous outcomes, with 95% confidence intervals (CIs). When possible, the data were pooled into meta-analysis using the random-effects model. GRADE was used to assess the quality of evidence for each outcome. Fourteen trials were included, totalling 1260 participants, with 1361 trigger fingers. The age of participants included in the studies ranged from 16 to 88 years; and the majority of participants were women (approximately 70%). The average duration of symptoms ranged from three to 15 months, and the follow-up after the procedure ranged from eight weeks to 23 months.The studies reported nine types of comparisons: open surgery versus steroid injections (two

Innovation in Surgery

PubMed Central

Riskin, Daniel J.; Longaker, Michael T.; Gertner, Michael; Krummel, Thomas M.

2006-01-01

Objective: To describe the field of surgical innovation from a historical perspective, applying new findings from research in technology innovation. Background: While surgical innovation has a rich tradition, as a field of study it is embryonic. Only a handful of academic centers of surgical innovation exist, all of which have arisen within the last 5 years. To this point, the field has not been well defined, nor have future options to promote surgical innovation been thoroughly explored. It is clear that surgical innovation is fundamental to surgical progress and has significant health policy implications. A process of systematically evaluating and promoting innovation in surgery may be critical in the evolving practice of medicine. Methods: A review of the academic literature in technology innovation was undertaken. Articles and books were identified through technical, medical, and business sources. Luminaries in surgical innovation were interviewed to develop further relevance to surgical history. The concepts in technology innovation were then applied to innovation in surgery, using the historical example of surgical endoscopy as a representative area, which encompasses millennia of learning and spans multiple specialties of care. Results: The history of surgery is comprised largely of individual, widely respected surgeon innovators. While respecting individual accomplishments, surgeons as a group have at times hindered critical innovation to the detriment of our profession and patients. As a clinical discipline, surgery relies on a tradition of research and attracting the brightest young minds. Innovation in surgery to date has been impressive, but inconsistently supported. Conclusion: A body of knowledge on technology innovation has been developed over the last decade but has largely not been applied to surgery. New surgical innovation centers are working to define the field and identify critical aspects of surgical innovation promotion. It is our

2011-01-01

Background and Objectives: We present a case of Laparoendoscopic Single Site Surgery (LESS) left adrenalectomy performed with a conventional laparoscope and instruments. Methods: A 45-year-old male was diagnosed with hyperaldosteronism. Computed tomography detected a left adrenal nodule. Bilateral adrenal vein sampling was consistent with a left-sided source for hyperaldosteronism. Results: Total operative time for LESS left adrenalectomy was 120 minutes. The surgery was performed with conventional instruments, a standard 5-mm laparoscope, and a SILS port, with no additional incisions or trocars needed. No complications occurred, and the patient reported an uneventful recovery. Conclusions: LESS adrenalectomy is a feasible procedure. Although articulating instruments and laparoscopes may offer advantages, LESS adrenalectomy can be done without these. PMID:21902983

Primary chondrosarcoma of the trachea is an extremely rare non-epithelial neoplasm with only few cases published in the literature. We present a rare case of tracheal chondrosarcoma with extensive extraluminal growth. We operated a patient with obstructive tumour of the upper third of the trachea via partial sternotomy. Before surgery, a Hanarostent was put into the trachea to treat a life-threatening stenosis. Postoperative period was uneventful. We discuss the incidence, clinical presentation and treatment options in patients with rare tracheal tumours. In some cases, a multidisciplinary approach (endoscopic intervention followed by surgical resection) is an effective treatment tool. © The Author 2017.

2018-01-01

Introduction Rectal prolapse is the complete protrusion of the rectum through the anal canal, incarceration rarely complicates rectal prolapse. Even more rarely, it becomes strangulated and gangrenous, necessitating emergency surgery. Case presentation We present the first reported case of strangulated acute rectal prolapse as the first manifestation of rectal prolapse. The patient was a 26-year-old man who presented with a 20×6 cm semi-spherical mass extra-anally. Rectosigmoidectomy with sacral rectopexy was performed, resecting 20 cm of the incarcerated rectum and sigmoid colon. The postoperative course was uneventful with a good final result after colostomy closure and continuity restoration. Conclusion The successful treatment of this patient illustrates the value of surgery in this difficult and unusual case scenario of rectal incarceration.

Drain site evisceration of fallopian tube, another reason to discourage abdominal drain: report of a case and brief review of literature.

2012-04-01

Placement of a drain following abdominal surgery is common despite a lack of convincing evidence in the current literature to support this practice. The use of intra-abdominal drain is associated with many potential and serious complications. We report a drain site evisceration of the right fallopian tube after the removal of an intra-abdominal drain. The drain was placed in the right iliac fossa in a patient who underwent a lower segment Caesarean section (LSCS) for meconium liquor with fetal distress. The Pfannenstiel incision made for LSCS was reopened and the protruding inflamed fimbrial end of the right fallopian tube was excised. The patient made an uneventful recovery. Routine intra-abdominal prophylactic drain following an abdominal surgery including LSCS should be discouraged.

The particular anatomic location of the hepatic caudate lobe between the hilar plate and inferior vena cava means that it is still considered unsuitable for laparoscopic measures and a difficult site even for conventional surgery. Here we describe the first case to be reported in the literature of caudate lobe resection for a single metastasis from breast adenocarcinoma that was completed using an exclusively laparoscopic procedure and a simplified scheme involving the placement of 4 trocars, without any need for conversion or the Pringle maneuver. The patient was 31 years old with a history of radical right mastectomy and chemotherapy. The patient's postoperative course was uneventful and she was discharged 4 days after the surgery. Twelve months on, she is currently alive and disease free.

2006-09-01

To report the clinical picture of the rare association of nanophthalmos and pigmentary retinal dystrophy and its cataract surgery outcome. We report a case of a 60-year-old female who presented with bilateral slowly progressive visual loss. The patient presented with bilateral light perception visual acuity, exotropia, brunescent cataract hindering fundus examination and hypodontia. Ultrasonography revealed bilateral nanophthalmos. A visual-evoked potential was also performed preoperatively. Cataract surgery with +40D IOL implantation was uneventful. Postoperative fundus examination revealed pigmentary retinal dystrophy, confirmed by electrophysiologic tests. Glycosaminoglycan urinary excretion was normal. Congenital bilateral nanophthalmos may rarely be associated with pigmentary retinal dystrophy. We suggest thorough preoperative evaluation in nanophthalmic eyes for the exclusion of significant features concerning visual prognosis.

2014-01-01

Most medical schools in the United States use the National Board of Medical Examiners Subject Examinations as a method of at least partial assessment of student performance, yet there is still uncertainty of how well these examination scores correlate with clinical proficiency. Thus, we investigated which factors in a surgery clerkship curriculum have a positive effect on academic achievement on the National Board of Medical Examiners Subject Examination in Surgery. A retrospective analysis of 83 third-year medical students at our institution with 4 unique clinical experiences on the general surgery clerkship for the 2007-2008 academic year was conducted. Records of the United States Medical Licensing Examination Step 1 scores, National Board of Medical Examiners Subject Examination in Surgery scores, and essay examination scores for the groups were compared using 1-way analysis of variance testing. Rush University Medical Center, Chicago IL, an academic institution and tertiary care center. Our data demonstrated National Board of Medical Examiners Subject Examination in Surgery scores from the group with the heavier clinical loads and least time for self-study were statistically higher than the group with lighter clinical services and higher rated self-study time (p = 0.036). However, there was no statistical difference of National Board of Medical Examiners Subject Examination in Surgery scores between the groups with equal clinical loads (p = 0.751). Students experiencing higher clinical volumes on surgical services, but less self-study time demonstrated statistically higher academic performance on objective evaluation, suggesting clinical experience may be of higher value than self-study and reading.

Wide Awake Hand Surgery.

Lied, Line; Borchgrevink, Grethe E; Finsen, Vilhjalmur

2017-09-01

"Wide awake hand surgery", where surgery is performed in local anaesthesia with adrenaline, without sedation or a tourniquet, has become widespread in some countries. It has a number of potential advantages and we wished to evaluate it among our patients. All 122 patients treated by this method during one year were evaluated by the surgeons and the patients on a numerical scale from 0 (best/least) to 10 (worst/most). Theatre time was compared to that recorded for a year when regional or general anaesthesia had been used. The patients' mean score for the general care they had received was 0.1 (SD 0.6), for pain during lidocaine injection 2.4 (SD 2.2), for pain during surgery 0.9 (SD 1.5), and for other discomfort during surgery 0.5 (SD 1.4). Eight reported that they would want general anaesthesia if they were to be operated again. The surgeons' mean evaluation of bleeding during surgery was 1.6 (SD 1.8), oedema during surgery 0.4 (SD 1.1), general disadvantages with the method 1.0 (SD 1.6) and general advantages 6.5 (SD 4.3). The estimation of advantages was 9.9 (DS 0.5) for tendon suture. 28 patients needed intra-operative additional anaesthesia. The proportion was lower among trained hand surgeons and fell significantly during the study period. Non-surgical theatre time was 46 (SD 15) minutes during the study period and 55 (SD 22) minutes during the regional/general period (p < 0.001). This gain was cancelled out by a longer surgery time during the wide awake period. Wide awake surgery is fully acceptable to most patients. It has a number of advantages over general or regional anaesthesia, but we feel it is unlikely to improve the efficiency of the operating theatre.

Incorporating emergency general surgery into the current practice of the trauma and critical care surgeon carries sweeping implications for future practice and training. Herein, we examine the known benefits of the practice of emergency general surgery, contrast it with the emerging paradigm of acute care surgery, and examine pitfalls already encountered in integration of emergency general surgery into a traditional trauma/critical care surgery service. A MEDLINE literature search was supplemented with local experience and national presentations at major meetings to provide data for this review. Considerations including faculty complement, service structure, resident staffing, physician extenders, the decreased role of community hospitals in providing trauma and emergency general surgery care, and the effects on an elective operative schedule are inadequately explored at present. There are no firm recommendations as to how to incorporate emergency general surgery into a trauma/critical care practice that will satisfy both academic and community practice paradigms. The near future seems likely to embrace the expanded training and clinical care program termed acute care surgery. A host of essential elements have yet to be examined to undertake a critical analysis of the applicability, advisability, and appropriate structure of both emergency general surgery and acute care surgery in the United States. Proceeding along this pathway may be fraught with training, education, and implementation pitfalls that are ideally addressed before deploying acute care surgery as a national standard.

The roots of science and art of plastic surgery are very antique. Anatomy, drawing, painting, and sculpting have been very important to the surgery and medicine development over the centuries. Artistic skills besides shape, volume, and lines perception can be a practical aid to the plastic surgeons' daily work. An overview about the interactions between art and plastic surgery is presented, with a few applications to rhinoplasty, cleft lip, and other reconstructive plastic surgeries.

A 38-year-old woman presented with a lifelong history of involuntary urinary leakage. The patient reported that she had been operated for her urinary leakage with the diagnosis of stress incontinence with transobturator tape two times at two different institutions. Preoperative computed tomography scan showed complete duplication of the left kidney with poorly functioning upper pole and a tortuous left dilated ureter running down and opening into the vagina. Laparoscopic left upper pole heminephrectomy and ureterectomy were performed uneventfully. Her incontinence improved immediately after surgery.

Gutierrez, Luis B., E-mail: lbgutier@stanford.edu; Bansal, Anshuman K., E-mail: abansal@mednet.ucla.edu; Hovsepian, David M., E-mail: hovsepian@stanford.edu

A 44-year-old woman underwent uncomplicated uterine fibroid embolization (UFE) for menstrual and bulk-related symptoms in an enlarged, myomatous uterus. After surgery, she spontaneously sloughed a large mass of fibroids that arrested in the cervical canal during passage. Four days after gynecological extraction, she developed copious vaginal discharge that contained enteric contents. Contrast-enhanced computed tomography (CT) demonstrated a fistula between the small bowel and the uterus. She subsequently underwent hysterectomy, left oophorectomy, and small-bowel resection. Her postoperative recovery was uneventful.

Coronary heart disease (CHD) is the leading cause of morbidity and mortality worldwide. For a large number of patients with CHD, coronary artery bypass graft (CABG) surgery remains the preferred strategy for coronary revascularization. Over the last 10 years, the number of high-risk patients undergoing CABG surgery has increased significantly, resulting in worse clinical outcomes in this patient group. This appears to be related to the ageing population, increased co-morbidities (such as diabetes, obesity, hypertension, stroke), concomitant valve disease, and advances in percutaneous coronary intervention which have resulted in patients with more complex coronary artery disease undergoing surgery. These high-risk patients are more susceptible to peri-operative myocardial injury and infarction (PMI), a major cause of which is acute global ischaemia/reperfusion injury arising from inadequate myocardial protection during CABG surgery. Therefore, novel therapeutic strategies are required to protect the heart in this high-risk patient group. In this article, we review the aetiology of PMI during CABG surgery, its diagnosis and clinical significance, and the endogenous and pharmacological therapeutic strategies available for preventing it. By improving cardioprotection during CABG surgery, we may be able to reduce PMI, preserve left ventricular systolic function, and reduce morbidity and mortality in these high-risk patients with CHD.

To analyze current indications for transsphenoidal pituitary surgery. The current literature regarding transsphenoidal surgery for all subtypes of pituitary adenomas and other sellar lesions was examined. Alternate approaches for pituitary surgery were also reviewed. Transsphenoidal surgery continues to be the mainstay of surgical treatment for pituitary tumors, and has good outcomes in experienced hands. Pre- and postoperative management of pituitary tumors remains an important part of the treatment of patients with pituitary tumors. Even as medical and surgical treatment for pituitary tumors evolves, transsphenoidal surgery remains a mainstay of treatment. Outcomes after transshenoidal surgery have improved over time. Neurosurgeons must be aware of the indications, risks and alternatives to transsphenoidal pituitary surgery. Copyright © 2014 Elsevier Inc. All rights reserved.

Robotic surgery of the pancreas

Pancreatic surgery is one of the most challenging and complex fields in general surgery. While minimally invasive surgery has become the standard of care for many intra-abdominal pathologies the overwhelming majority of pancreatic surgery is performed in an open fashion. This is attributed to the retroperitoneal location of the pancreas, its intimate relationship to major vasculature and the complexity of reconstruction in the case of pancreatoduodenectomy. Herein, we describe the application of robotic technology to minimally invasive pancreatic surgery. The unique capabilities of the robotic platform have made the minimally invasive approach feasible and safe with equivalent if not better outcomes (e.g., decreased length of stay, less surgical site infections) to conventional open surgery. However, it is unclear whether the robotic approach is truly superior to traditional laparoscopy; this is a key point given the substantial costs associated with procuring and maintaining robotic capabilities.

Bariatric surgery for morbid obesity results in massive weight loss and improvement of health and quality of life. A downside of the major weight loss is the excess of overstretched skin, which may influence the patient's quality of life by causing functional and aesthetic problems. The purpose of the current study was to evaluate the patient's quality of life long-term after body contouring following bariatric surgery. Quality of life was measured with the Obesity Psychosocial State Questionnaire in 33 post-bariatric surgery patients 7.2 years (range, 3.2 to 13.3 years) after body contouring surgery. Data were compared with previous assessments 4.1 years (range, 0.7 to 9.2 years) after body contouring surgery of the quality of life at that time and before body contouring surgery. Compared with appraisals of quality of life before body contouring surgery, a significant, mostly moderate to large, sustained improvement of quality of life was observed in post-bariatric surgery patients 7.2 years after body contouring surgery in six of the seven psychosocial domains. A small deterioration occurred between 4.1- and 7.2-year follow-up on two of the seven domains except for the domain efficacy toward eating, which showed a significant improvement. At 7-year follow-up, 18 patients (55 percent) were satisfied with the result of body contouring surgery. This study indicates a sustained quality-of-life improvement in post-bariatric surgery patients after body contouring surgery. This suggests the importance of including reconstructive surgery as a component in the multidisciplinary approach in the surgical treatment of morbid obesity. Therapeutic, IV.

Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients. Five cases (0,025%) of intestinal malrotation were found. All of them were males, aging 45, 49, 37,52 and 39 years; BMI 35, 42, 49, 47 and 52 kg/m2, all of them with a past medical history of morbid obesity. The patient with BMI 35 kg/m2 suffered from type 2 diabetes also. All procedures were completed by laparoscopic approach, with no conversions. In one patient was not possible to move the jejunum to the upper abdomen in order to establish the gastrojejunostomy and a sleeve gastrectomy was performed. In another patient was not possible to fully recognize the anatomy due to bowel adhesions and a single anastomosis gastric bypass was preferred. No leaks or bleeding were identified. There were no perioperative complications. All patients were discharged 72 h after the procedure and no immediate 30-day complications were reported. Patients with malrotation can successfully undergo laparoscopic bariatric surgery. May be necessary changes in the surgical original strategy regarding the malrotation. Surgeons must check full abdominal anatomical condition prior to start the division of the stomach.

Antireflux surgery.

Gastro-oesophageal reflux disease is extremely common throughout Europe and the United States. This review on antireflux surgery examines the best evidence for surgical treatment of gastro-esophageal reflux disease. Comparison is made with medical antireflux therapy including histamine H2 receptor antagonist and proton pump inhibitor therapy. The randomized trials and systematic reviews available on gastro-esophageal reflux disease are reviewed and where data are scarce, the largest cohort studies available are discussed. Overall, laparoscopic antireflux surgery is safe and has a similar efficacy to open antireflux surgery and best medical therapy with proton pump inhibitors. There is a failure rate, which in some series is greater than 50% at 5 years. Due to the cost of a proportion of patients still taking antireflux medications, it cannot be recommended on cost-effectiveness grounds over best medical therapy. The choice of procedure lies between complete wrap with Nissen's fundoplication and partial fundoplication (most frequently Toupet). Division of the short gastric vessels is not usually necessary and is associated with increased wind-related complications. Total fundoplication tends to produce superior reflux control, but at the cost of increased risk of dysphagia. There is a trend for antireflux surgery to be superior to best medical therapy in cancer prevention in Barrett's oesophagus, but this has not reached statistical significance.

Fetal Surgery

Fetal surgery has come of age. For decades experimental fetal surgery proved essential in studying normal fetal physiology and development, and pathophysiology of congenital defects. Clinical fetal surgery started in the 1960s with intrauterine transfusions. In the 1970s, the advent of ultrasonography revolutionized fetal diagnosis and created a therapeutic vacuum. Fetal treatment, medical and surgical, is slowly trying to fill the gap. Most defects detected are best treated after birth, some requiring a modification in the time, mode and place of delivery for optimal obstetrical and neonatal care. Surgical intervention in utero should be considered for malformations that cause progressive damage to the fetus, leading to death or severe morbidity; that can be corrected or palliated in utero with a reasonable expectation of normal postnatal development; that cannot wait to be corrected after birth, even considering pre-term delivery; that are not accompanied by chromosomal or other major anomalies. At present, congenital hydronephrosis is the most common indication for fetal surgery, followed by obstructive hydrocephalus. Congenital diaphragmatic hernia also fulfills the criteria, but its correction poses more problems, and no clinical attempts have been reported so far. In the future many other malformations or diseases may become best treated in utero. The ethical and moral issues are complex and need to be discussed as clinical and experimental progress is made.

Despite the importance of timely evaluation for patients with brachial plexus injuries (BPIs), in clinical practice we have noted delays in referral. Because the published BPI experience is largely from individual centers, we used a population-based approach to evaluate the delivery of care for patients with BPI. We used statewide administrative databases from Florida (2007-2013), New York (2008-2012), and North Carolina (2009-2010) to create a cohort of patients who underwent surgery for BPI (exploration, repair, neurolysis, grafting, or nerve transfer). Emergency department and inpatient records were used to determine the time interval between the injury and surgical treatment. Distances between treating hospitals and between the patient's home ZIP code and the surgical hospital were recorded. A multivariable logistic regression model was used to determine predictors for time from injury to surgery exceeding 365 days. Within the 222 patients in our cohort, median time from injury to surgery was 7.6 months and exceeded 365 days in 29% (64 of 222 patients) of cases. Treatment at a smaller hospital for the initial injury was significantly associated with surgery beyond 365 days after injury. Patient insurance type, travel distance for surgery, distance between the 2 treating hospitals, and changing hospitals between injury and surgery did not significantly influence time to surgery. Nearly one third of patients in Florida, New York, and North Carolina underwent BPI surgery more than 1 year after the injury. Patients initially treated at smaller hospitals are at risk for undergoing delayed BPI surgery. These findings can inform administrative and policy efforts to expedite timely referral of patients with BPI to experienced centers. Copyright © 2016 American Society for Surgery of the Hand.

Robotics in Colorectal Surgery

Over the past few decades, robotic surgery has developed from a futuristic dream to a real, widely used technology. Today, robotic platforms are used for a range of procedures and have added a new facet to the development and implementation of minimally invasive surgeries. The potential advantages are enormous, but the current progress is impeded by high costs and limited technology. However, recent advances in haptic feedback systems and single-port surgical techniques demonstrate a clear role for robotics and are likely to improve surgical outcomes. Although robotic surgeries have become the gold standard for a number of procedures, the research in colorectal surgery is not definitive and more work needs to be done to prove its safety and efficacy to both surgeons and patients.

Bone Metabolism after Bariatric Surgery

Yu, Elaine W.

2014-01-01

Bariatric surgery is a popular and effective treatment for severe obesity, but may have negative effects on the skeleton. This review summarizes changes in bone density and bone metabolism from animal and clinical studies of bariatric surgery, with specific attention to Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB), and sleeve gastrectomy (SG). Skeletal imaging artifacts from obesity and weight loss are also considered. Despite challenges in bone density imaging, the preponderance of evidence suggests that bariatric surgery procedures have negative skeletal effects that persist beyond the first year of surgery, and that these effects vary by surgical type. The long-term clinical implications and current clinical recommendations are presented. Further study is required to determine mechanisms of bone loss after bariatric surgery. Although early studies focused on calcium/vitamin D metabolism and mechanical unloading of the skeleton, it seems likely that surgically-induced changes in the hormonal and metabolic profile may be responsible for the skeletal phenotypes observed after bariatric surgery.

We seek to provide a background of the current state of pediatric urologic surgery including a brief history, procedural outcomes, cost considerations, future directions, and the state of robotic surgery in India. Pediatric robotic urology has been shown to be safe and effective in cases ranging from pyeloplasty to bladder augmentation with continent urinary diversion. Complication rates are in line with other methods of performing the same procedures. The cost of robotic surgery continues to decrease, but setting up pediatric robotic urology programs can be costly in terms of both monetary investment and the training of robotic surgeons. The future directions of robot surgery include instrument and system refinements, augmented reality and haptics, and telesurgery. Given the large number of children in India, there is huge potential for growth of pediatric robotic urology in India. Pediatric robotic urologic surgery has been established as safe and effective, and it will be an important tool in the future of pediatric urologic surgery worldwide. PMID:25197187

Entrepreneurial skills are important for physicians, especially plastic surgeons. Nevertheless, these skills are not typically emphasized during residency training. Evaluate the extent of business training at plastic surgery residency programs as well as means of enhancing business training. A 6-question online survey was sent to plastic surgery program directors for distribution to plastic surgery residents. Responses from residents at the PGY2 level and above were included for analysis. Tables were prepared to present survey results. Hundred and sixty-six residents including 147 PGY2 and above residents responded to our survey. Only 43.5% reported inclusion of business training in their plastic surgery residency. A majority of residents reported they do not expect on graduation to be prepared for the business aspects of plastic surgery. Additionally, a majority of residents feel establishment of a formal lecture series on the business of plastic surgery would be beneficial. Results from our survey indicate limited training at plastic surgery programs in necessary business skills. Plastic surgery residency programs should consider incorporating or enhancing elements of business training in their curriculum.

Innovations in Bariatric Surgery.

Surgery has consistently been demonstrated to be the most effective long-term therapy for the treatment of obesity. However, despite excellent outcomes with current procedures, most patients with obesity- and weight-related comorbidities who meet criteria for surgical treatment choose not to pursue surgery out of fear of operative risks and complications or concerns about high costs. Novel minimally invasive procedures and devices may offer alternative solutions for patients who are hesitant to pursue standard surgical approaches. These procedures may be used for primary treatment of obesity, early intervention for patients approaching morbid obesity, temporary management prior to bariatric surgery, or revision of bypass surgery associated with weight regain. Novel bariatric procedures can in general be divided into four categories: endoluminal space-occupying devices, gastric suturing and restrictive devices, absorption-limiting devices, and neural-hormonal modulating devices. Many of these are only approved as short-term interventions, but these devices may be effective for patients desiring low-risk procedures or a transient effect. We will see the expansion of indications and alternatives for metabolic surgery as these techniques gain approval.

On 10 February 2012, a Strategic Conference was organized by the European Association for Cardio-Thoracic Surgery (EACTS) in Windsor during the inauguration of the newly acquired EACTS house. In this review, the present and future of thoracic surgery are discussed. With the creation of the Thoracic Domain, thoracic surgery has been strengthened and made clearly visible within the general EACTS structure. A clearly identified thoracic track is provided during the Annual Congress. Specific working groups have been created that deal with varying topics of thoracic surgery and diseases of the chest. The European School of Cardiothoracic Surgery has been restructured, providing not only theoretical but also practical education in thoracic surgery. At national and international levels, interdisciplinary cooperation is encouraged. Harmonization of thoracic training within Europe is necessary to allow better exchange between different countries. Guidelines dealing with specific thoracic procedures should be further developed. The Thoracic Domain of EACTS will remain a key player in promoting thoracic surgery in Europe and internationally, and in providing high-level scientific output, education and training in thoracic surgery and diseases of the chest, which requires continuous, close cooperation between thoracic and cardiothoracic surgeons.

To determine the incidence and the risk factors involved in the development of the three main postoperative capsular complications: posterior capsule opacification (PCO), capsular bag distension syndrome (CBDS), and anterior capsular phimosis syndrome (ACP). A retrospective cohort study was conducted on 801 patients submitted to cataract surgery in the ophthalmology unit of Hospital del Henares (Madrid) from March 2, 2009 to February 28, 2010. Computerized clinical charts were reviewed during July 2012. PCO was studied using the Kaplan-Meier method (log rank test). A total of 167 patients developed PCO. No association could be demonstrated between PCO and age, sex, diabetes mellitus, phaco technique, IOL model, tamsulosin intake, glaucoma, and age-related macular degeneration. Three patients developed CBDS, all of them have received and Akreos Adapt AO(®) (Bausch & Lomb). Two of them were young men who had received surgery for posterior subcapsular cataracts. Three patients developed ACP, 2 of whom had received a MicroSlim(®) IOL (PhysIOL). No association was found between PCO and any of the studied variables. Male gender, young age, subcapsular cataract and large non-angulated lens such as Akreos Adapt AO(®) could be associated with CBDS. ACP could be more frequent when microincision IOLs (like MicroSlim(®)) are implanted. Copyright © 2013 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.U. All rights reserved.

Designing an effective hand rotation for plastic surgery residents is difficult. The authors address this limitation by elucidating the critical components of the hand curriculum during plastic surgery residency. Hand questions on the Plastic Surgery In-Service Training Exam for six consecutive years (2008 to 2013) were characterized by presence of imaging, vignette setting, question taxonomy, answer domain, anatomy, and topic. Answer references were quantified by source and year of publication. Two hundred sixty-six questions were related to hand surgery (22.7 percent of all questions; 44.3 per year) and 61 were accompanied by an image (22.9 percent). Vignettes tended to be clinic- (50.0 percent) and emergency room-based (35.3 percent) (p < 0.001). Questions required decision-making (60.5 percent) over interpretation (25.9 percent) and recall skills (13.5 percent) (p < 0.001). Answers focused on interventions (57.5 percent) over anatomy/pathology (25.2 percent) and diagnoses (17.3 percent) (p < 0.001). Nearly half of the questions focused on the digits. The highest yield topics were trauma (35.3 percent), reconstruction (24.4 percent), and aesthetic and functional problems (14.2 percent). The Journal of Hand Surgery (American volume) (20.5 percent) and Plastic and Reconstructive Surgery (18.0 percent) were the most-cited journals, and the median publication lag was 7 years. Green's Operative Hand Surgery was the most-referenced textbook (41.8 percent). These results will enable trainees to study hand surgery topics with greater efficiency. Faculty can use these results to ensure that tested topics are covered during residency training. Thus, a benchmark is established to improve didactic, clinical, and operative experiences in hand surgery.

Photobiomodulation in laser surgery

Laser surgery provides good exposure with clear operating fields and satisfactory preliminary functional results. In contrast to conventional excision, it was found that matrix metalloproteinases and the tissue inhibitors of metalloproteinases -1 mRNA expression is higher, myofibroblasts appeared and disappeared slower in laser excision wounds. It has been suggested that the better anatomical and functional results achieved following laser cordectomy may be explained by the fact that such procedures result in better, more rapid healing processes to recover vocal cord for early glottic tumors and better. In this paper, the role of photobiomodulation in laser surgery will be discussed by the cultured monolayer normal human skin fibroblast model of the photobiomodulation of marginal irradiation of high intensity laser beam, the photobiomodulation related to the irradiated tissue, the biological information model of photobiomodulation and the animal models of laser surgery. Although high intensity laser beam is so intense that it destroys the irradiated cells or tissue, its marginal irradiation intensity is so low that there is photobiomodulation on non-damage cells to modulate the regeneration of partly damaged tissue so that the surgery of laser of different parameters results in different post-surgical recovery. It was concluded that photobiomodulation might play an important role in the long-term effects of laser surgery, which might be used to design laser surgery.

Recently published reports have established a heparin-induced thrombocytopenia (HIT)-mimicking thromboembolic disorder without proximate heparin exposure, called spontaneous HIT syndrome. Although the pathophysiology remains unclear, anti-platelet factor 4 (PF4)/heparin antibodies possibly triggered by exposure to knee cartilage glycosaminoglycans or other non-heparin polyanions found on bacterial surfaces and nucleic acids have been postulated. We present a 53-year-old female receiving antithrombotic prophylaxis with aspirin following right total knee replacement surgery (without perioperative or any previous lifetime heparin exposure) who acutely presented with high-risk pulmonary embolism (PE) and right great saphenous vein thrombophlebitis on postoperative day (POD) 14; her platelet count at presentation was 13 × 10 9 /L. Prior to diagnostic consideration of spontaneous HIT syndrome, the patient briefly received unfractionated heparin (UFH) and one dose of enoxaparin. The patient's serum tested strongly positive for anti-PF4/heparin antibodies by two different PF4-dependent enzyme-linked immunosorbent assays (ELISAs) and by serotonin release assay (SRA). Failure of fondaparinux anticoagulation (persisting HIT-associated disseminated intravascular coagulation) prompted switching to argatroban. Severe thrombocytopenia persisted (platelet count nadir, 12 × 10 9 /L, on POD21), and 9 days after starting argatroban symptomatic right leg deep-vein thrombosis (DVT) occurred, prompting switch to rivaroxaban. Thereafter, her course was uneventful, although platelet count recovery was prolonged, reaching 99 × 10 9 /L by POD45 and 199 × 10 9 /L by POD79. The patient's serum elicited strong serotonin release in the absence of heparin (seen even with 1/32 serum dilution) that was enhanced by pharmacological concentrations of UFH (0.1 and 0.3 IU/mL) and fondaparinux (0.1-1.2 μg/mL, i.e., in vitro fondaparinux "cross-reactivity"). Ultimately, platelet count recovery was

Metabolic syndrome (MS) is common among morbidly obese patients undergoing bariatric surgery. The aim of this study was to assess the impact and predictors of bariatric surgery on the resolution of MS. Subjects included 286 patients [age 44.0 +/- 11.5, female 78.2%, BMI 48.7 +/- 9.4, waist circumference 139 +/- 20 cm, AST 23.5 +/- 14.9, ALT 30.0 +/- 20.1, type 2 diabetes mellitus (DM) 30.1% and MS 39.2%] who underwent bariatric surgery. Of the entire cohort, 27.3% underwent malabsorptive surgery, 55.9% underwent restrictive surgery, and 16.8% had combination restrictive-malabsorptive surgery. Mean weight loss was 33.7 +/- 20.1 kg after restrictive surgery (follow up period 298 +/- 271 days), 39.4 +/- 22.9 kg after malabsorptive surgery (follow-up period 306 +/- 290 days), and 28.3 +/- 14.1 kg after combination surgery (follow-up period 281 +/- 239 days). Regardless of the type of bariatric surgery, significant improvements were noted in MS (p values from <0.0001-0.01) as well as its components such as DM (p values from <0.0001-0.0005), waist circumference (p values <0.0001), BMI (p values <0.0001), fasting serum triglycerides (p values <0.0001 to 0.001), and fasting serum glucose (p values <0.0001). Additionally, a significant improvement in AST/ALT ratio (p value = 0.0002) was noted in those undergoing restrictive surgery. Multivariate analysis showed that patients who underwent malabsorptive bariatric procedures experienced a significantly greater percent excess weight loss than patients who underwent restrictive procedures (p value = 0.0451). Percent excess weight loss increased with longer postoperative follow-up (p value <0.0001). Weight loss after bariatric surgery is associated with a significant improvement in MS and other metabolic factors.

Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

The high variability in cardiac surgery length--is one of the main challenges for staff managing productivity. This study aims to evaluate the impact of six interventions on open-heart surgery operating theatre productivity. A discrete operating theatre event simulation model with empirical operation time input data from 2603 patients is used to evaluate the effect that these process interventions have on the surgery output and overtime work. A linear regression model was used to get operation time forecasts for surgery scheduling while it also could be used to explain operation time. A forecasting model based on the linear regression of variables available before the surgery explains 46 per cent operating time variance. The main factors influencing operation length were type of operation, redoing the operation and the head surgeon. Reduction of changeover time between surgeries by inducing anaesthesia outside an operating theatre and by reducing slack time at the end of day after a second surgery have the strongest effects on surgery output and productivity. A more accurate operation time forecast did not have any effect on output, although improved operation time forecast did decrease overtime work. A reduction in the operation time itself is not studied in this article. However, the forecasting model can also be applied to discover which factors are most significant in explaining variation in the length of open-heart surgery. The challenge in scheduling two open-heart surgeries in one day can be partly resolved by increasing the length of the day, decreasing the time between two surgeries or by improving patient scheduling procedures so that two short surgeries can be paired. A linear regression model is created in the paper to increase the accuracy of operation time forecasting and to identify factors that have the most influence on operation time. A simulation model is used to analyse the impact of improved surgical length forecasting and five selected process

The Association of Surgeons of South Africa (ASSA), because of a concern about the decline in the number of applicants for registrar posts, undertook this study into the various factors that may influence the choice of surgery as career option. The study involved a combination of desk research and structured interviews with heads of departments, specialists, and registrars in general surgery. The reasons for choosing general surgery as a career included the immediately visible results of a surgeon's efforts and the practical and intellectual challenge of the specialty. General surgery continued to enjoy a high status in society. The greater focus on primary health care has affected facilities at tertiary and secondary institutions. General surgeons worked excessively long hours, which was associated with increased levels of stress and placed severe strains on family life. All respondents felt that their levels of remuneration were 'poor' in relation to other disciplines and professions. In this study we identified various factors that impacted either positively or negatively on the choice of general surgery as a career option.

This review provides a literature overview of new findings relating nutritional genomics and bariatric surgery. It also describes the importance of nutritional genomics concepts in personalized bariatric management. It includes a discussion of the potential role bariatric surgery plays in altering the three pillars of nutritional genomics: nutrigenetics, nutrigenomics, and epigenetics. We present studies that show the effect of each patient’s genetic and epigenetic variables on the response to surgical weight loss treatment. We include investigations that demonstrate the association of single nucleotide polymorphisms with obesity phenotypes and their influence on weight loss after bariatric surgery. We also present reports on how significant weight loss induced by bariatric surgery impacts telomere length, and we discuss studies on the existence of an epigenetic signature associated with surgery outcomes and specific gene methylation profile, which may help to predict weight loss after a surgical procedure. Finally, we show articles which evidence that bariatric surgery may affect expression of numerous genes involved in different metabolic pathways and consequently induce functional and taxonomic changes in gut microbial communities. The role nutritional genomics plays in responses to weight loss after bariatric surgery is evident. Better understanding of the molecular pathways involved in this process is necessary for successful weight management and maintenance. PMID:28878180

[Risk management for endoscopic surgery].

PubMed

Kimura, Taizo

2010-05-01

The number of medical accidents in endoscopic surgery has recently increased. Surgical complications caused by inadequate preparation or immature technique or those resulting in serious adverse outcomes may be referred to as medical accidents. The Nationwide Survey of Endoscopic Surgery showed that bile duct injury and uncontrollable bleeding were seen in 0.68% and in 0.58%, respectively, of cholecystectomy patients; interoperative and postoperative complications in 0.84% and in 3.8%, respectively, of gastric cancer surgery patients; and operative complications in 6.74% of bowel surgery patients. Some required open repair, and 49 patients died. The characteristic causes of complications in endoscopic surgery are a misunderstanding of anatomy, handling of organs outside the visual field, burn by electrocautery, and injuries caused by forceps. Bleeding that requires a laparotomy for hemostasis is also a complication. Furthermore, since the surgery is usually videorecorded, immature techniques resulting in complications are easily discovered. To decrease the frequency of accidents, education through textbooks and seminars, training using training boxes, simulators, or animals, proper selection of the surgeon depending on the difficulty of the procedure, a low threshold for conversion to laparotomy, and use of the best optical equipment and surgical instruments are important. To avoid malpractice lawsuits, informed consent obtained before surgery and proper communication after accidents are necessary.

Purpose Despite the importance of timely evaluation for patients with brachial plexus injuries (BPI), in clinical practice we have noted delays in referral. Because the published BPI experience is largely from individual centers, we used a population-based approach to evaluate the delivery of care for patients with BPI. Methods We used statewide administrative databases from Florida (2007–2013), New York (2008–2012) and North Carolina (2009–2010) to create a cohort of patients who underwent surgery for BPI (exploration, repair, neurolysis, grafting, or nerve transfer). Emergency department and inpatient records were used to determine the time interval between the injury and surgical treatment. The distances between the treating hospitals and between the patient’s home ZIP code and the surgical hospital were recorded. A multivariable logistic regression model was used to determine predictors for time from injury to surgery exceeding 365 days. Results Within the 222 patients in our cohort, the median time from injury to surgery was 7.6 months and exceeded 365 days in 29% of cases. Treatment at a smaller hospital for the initial injury was significantly associated with surgery beyond 365 days after injury. Patient insurance type, travel distance for surgery, the distance between the two treating hospitals, or changing hospitals between injury and surgery did not significantly influence time to surgery. Conclusions Nearly one-third of patients in FL, NY, and NC underwent BPI surgery more than one year after their injury. Patients initially treated at smaller hospitals are at risk for undergoing delayed BPI surgery. Clinical Relevance These findings can inform administrative and policy efforts to expedite timely referral of patients with BPI to experienced centers. PMID:27570225

The aim was to describe procedural volumes, patient risk profile and outcomes of heart valve surgery in the past 16 years in Netherlands. The Dutch National Database for Cardio-Thoracic Surgery includes approximately 200 000 cardiac operations performed between 1995 and 2010. Information on all valve surgeries (56 397 operations) was extracted. We determined trends for changes in procedural volume, demographics, risk profile and in-hospital mortality of valve operations. Because of incomplete data in the first years of registration, the total number of operations in those years was estimated using Poisson regression. For a subset from 2007 to 2010, follow-up data were available. Survival status was obtained through linkage with the national Cause of Death Registry, and survival analysis was performed using Kaplan-Meier method. Information on discharge and readmissions was obtained from the National Hospital Discharge Registry. The annual volume of heart valve operations increased by more than 100% from an estimated 2431 in 1995 to 5906 in 2010. Adjusted for population size in Netherlands, the number of operations per 100 000 adults increased from 20 in 1995 to 43 in 2010. In 2010, frequently performed valve surgery included the following: 34.6% isolated aortic valve (AoV) replacement, 21.8% AoV replacement and coronary artery bypass grafting (CABG), 14.6% isolated mitral valve surgery (repair or replacement) and 9.1% mitral valve and CABG. In AoV surgery, an increasing use of bioprostheses in all age categories is observed. In mitral valve surgery, 75.4% was performed by repair rather than replacement in 2010. In-hospital mortality for all valve surgery decreased significantly from 4.6% in 2007 to 3.6% in 2010, whereas the mean logistic EuroSCORE remained stable (median 5.8, P = 1.000). Thirty-day mortality after all valve surgery was 3.9% and 120-day mortality was 6.5%. At 1 year, survival after all valve surgery was 91.6% and a reoperation had been performed in 1

The effectiveness of perioperative antibiotic prophylaxis in reducing surgical site infections has been demonstrated. Its utility is recognized for clean-contaminated procedures and some clean surgeries. Prophylactic antibiotics are used as intended to cover the most common germs in the surgical site; first and second generation cephalosporins are the most used. For optimal prophylaxis, an antibiotic with a targeted spectrum should be administered at sufficiently high concentrations in serum, tissue, and the surgical wound during the time that the incision is open and risk of bacterial contamination. The infusion of the first dose of antimicrobial should begin within 60 min before surgical incision and should be discontinued within 24 h after the end of surgery The prolonged use of antibiotic prophylaxis leads to emergence of bacterial resistance and high costs. The principles of antimicrobial prophylaxis in cancer surgery are the same as those described for general surgery; it is recommended to follow and comply with the standard criteria. In mastectomies and clean head and neck surgery there are specific recommendations that differ from non-cancer surgery. In the case of very extensive surgeries, such as pelvic surgery or bone surgery with reconstruction, extension of antibiotics for 48-72 h should be considered.

Objectives. Bariatric surgery has been shown to be an effective intervention for weight loss and diabetes management. Despite this, many patients qualified for bariatric surgery are not interested in undergoing the procedure. The objective of this study is to determine the factors influencing receptivity to bariatric surgery among those who qualify for the procedure. Methods. Patients attending a publicly funded weight management clinic who qualified for bariatric surgery were asked to complete an elective questionnaire between February 2013 and April 2014. Results. A total of 371 patients (72% female) completed the questionnaire. Only 87 of 371 (23%) participants were interested in bariatric surgery. Individuals interested in bariatric surgery had a higher BMI (48.0 versus 46.2 kg/m2, P = 0.03) and believed that they would lose more weight with surgery (51 versus 44 kg, P = 0.0069). Those who scored highly on past weight loss success and financial concerns were less likely to be interested in bariatric surgery, whereas those who scored highly on high receptivity to surgery and positive social support were more likely to be interested in bariatric surgery. Conclusion. Although participants overestimated the effect of bariatric surgery on weight loss, most were still not interested in bariatric surgery. PMID:27516900

Interface Between Cosmetic and Migraine Surgery.

Gfrerer, Lisa; Guyuron, Bahman

2017-10-01

This article describes connections between migraine surgery and cosmetic surgery including technical overlap, benefits for patients, and why every plastic surgeon may consider screening cosmetic surgery patients for migraine headache (MH). Contemporary migraine surgery began by an observation made following forehead rejuvenation, and the connection has continued. The prevalence of MH among females in the USA is 26%, and females account for 91% of cosmetic surgery procedures and 81-91% of migraine surgery procedures, which suggests substantial overlap between both patient populations. At the same time, recent reports show an overall increase in cosmetic facial procedures. Surgical techniques between some of the most commonly performed facial surgeries and migraine surgery overlap, creating opportunity for consolidation. In particular, forehead lift, blepharoplasty, septo-rhinoplasty, and rhytidectomy can easily be part of the migraine surgery, depending on the migraine trigger sites. Patients could benefit from simultaneous improvement in MH symptoms and rejuvenation of the face. Simple tools such as the Migraine Headache Index could be used to screen cosmetic surgery patients for MH. Similarity between patient populations, demand for both facial and MH procedures, and technical overlap suggest great incentive for plastic surgeons to combine both.

Success of torsional correction surgery after failed surgeries for patellofemoral pain and instability.

2014-04-01

Torsional deformities of the femur and/or tibia often go unrecognized in adolescents and adults who present with anterior knee pain, and patellar maltracking or instability. While open and arthroscopic surgical techniques have evolved to address these problems, unrecognized torsion may compromise the outcomes of these procedures. We collected a group of 16 consecutive patients (23 knees), with mean age of 17, who had undergone knee surgery before torsion was recognized and subsequently treated by means of rotational osteotomy of the tibia and/or femur. By follow-up questionnaire, we sought to determine the role of rotational correction at mean 59-month follow-up. We reasoned that, by correcting torsional alignment, we might be able to optimize long-term outcomes and avert repeated knee surgery. Knee pain was significantly improved after torsional treatment (mean 8.6 pre-op vs. 3.3 post-op, p < 0.001), while 70 % of patients did have some continued knee pain postoperatively. Only 43 % of patients had continued patellar instability, and 57 % could trust their knee after surgery. Activity level remained the same or increased in 78 % of patients after torsional treatment. Excluding planned rod removal, subsequent knee surgery for continued anterior knee pain was undertaken on only 3 knees in 2 patients. We believe that malrotation of the lower limb not only raises the propensity for anterior knee symptoms, but is also a under-recognized etiology in the failure of surgeries for anterior knee pain and patellar instability. Addressing rotational abnormalities in the index surgery yields better clinical outcomes than osteotomies performed after other prior knee surgeries.

Since the emergence of minimally invasive technology twenty years ago, as a surgical concept and surgical technique for colorectal cancer surgery, its obvious advantages have been recognized. Laparoscopic technology, as one of the most important technology platform, has got a lot of evidence-based support for the oncological safety and effectiveness in colorectal cancer surgery Laparoscopic technique has advantages in terms of identification of anatomic plane and autonomic nerve, protection of pelvic structure, and fine dissection of vessels. But because of the limitation of laparoscopic technology there are still some deficiencies and shortcomings, including lack of touch and lack of stereo vision problems, in addition to the low rectal cancer, especially male, obese, narrow pelvis, larger tumors, it is difficult to get better view and manipulating triangle in laparoscopy. However, the emergence of a series of new minimally invasive technology platform is to make up for the defects and deficiencies. The robotic surgical system possesses advantages, such as stereo vision, higher magnification, manipulator wrist with high freedom degree, filtering of tremor and higher stability, but still has disadvantages, such as lack of haptic feedback, longer operation time, high operation cost and expensive price. 3D system of laparoscopic surgery has similar visual experience and feelings as robotic surgery in the 3D view, the same operating skills as 2D laparoscopy and a short learning curve. The price of 3D laparoscopy is also moderate, which makes the 3D laparoscopy more popular in China. Transanal total mesorectal excision (taTME) by changing the traditional laparoscopic pelvic surgery approach, may have certain advantages for male cases with narrow pelvic and patients with large tumor, and it is in accordance with the technical concept of natural orifice, with less minimally invasive and better cosmetics, which can be regarded as a supplemental technique of the

AIM To determine the incidence and risk factors of secondary glaucoma after pediatric cataract surgery. METHODS Two hundred and forty nine eyes of 148 patients underwent cataract surgery without intraocular lens (IOL) implantation (group 1), and 220 eyes of 129 patients underwent cataract surgery with IOL implantation (group 2) retrospectively, were evaluated between 2000 and 2011. The outcome measure was the presence or absence of post-cataract surgery glaucoma, defined as an intraocular pressure (IOP) ≥26mmHg, as measured on at least two occasions along with corneal or optic nerve changes. RESULTS The mean follow-up periods of group 1 and 2 were (60.86±30.95) months (12-123 months) and (62.11±31.29) months (14-115 months) respectively. In group 1, 12 eyes of 8 patients (4.8%) developed glaucoma. None of the patients developed glaucoma after surgery in group 2. The mean age of the patients at the cataract surgery was (2.58±0.90) months (1 month-4 months) and the average period for glaucoma development after surgery was (9.50±4.33) months (4-16 months) in group 1. Three of the 12 glaucomatous eyes were controlled with antiglaucomatous medication and 9 eyes underwent trabeculectomy+mitomycin C surgery. One patient underwent a second trabeculectomy + mitomycin C operation for both of his eyes. CONCLUSION The incidence of glaucoma after pediatric cataract surgery is very low in patients in whom IOL is implanted. The aphakic eyes after pediatric cataract surgery are at an increased risk for glaucoma development particularly if they underwent surgery before 4 months of age. PMID:23638427

Gender reassignment surgery: an overview.

Gender reassignment (which includes psychotherapy, hormonal therapy and surgery) has been demonstrated as the most effective treatment for patients affected by gender dysphoria (or gender identity disorder), in which patients do not recognize their gender (sexual identity) as matching their genetic and sexual characteristics. Gender reassignment surgery is a series of complex surgical procedures (genital and nongenital) performed for the treatment of gender dysphoria. Genital procedures performed for gender dysphoria, such as vaginoplasty, clitorolabioplasty, penectomy and orchidectomy in male-to-female transsexuals, and penile and scrotal reconstruction in female-to-male transsexuals, are the core procedures in gender reassignment surgery. Nongenital procedures, such as breast enlargement, mastectomy, facial feminization surgery, voice surgery, and other masculinization and feminization procedures complete the surgical treatment available. The World Professional Association for Transgender Health currently publishes and reviews guidelines and standards of care for patients affected by gender dysphoria, such as eligibility criteria for surgery. This article presents an overview of the genital and nongenital procedures available for both male-to-female and female-to-male gender reassignment.

ABSTRACT Objectives: to describe the feelings and perceptions resulting from gynecologic surgery by women and analyze how they experience the changes caused by the surgery. Method: a qualitative, descriptive and exploratory study, which had Symbolic Interactionism and Grounded Theory as its theoretical framework. Participants of the study: 13 women submitted to surgery: Total Abdominal Hysterectomy, Total Abdominal Hysterectomy with bilateral Adnexectomy, Wertheim-Meigs surgery, Oophorectomy, Salpingectomy, Mastectomy, Quadrantectomy and Tracheloplasty. Individual interviews were conducted, recorded and analyzed according to the comparative analysis technique of the Grounded Theory. Results: from the data two categories emerged - Perceiving a different body and feeling as a different person and; building the meaning of mutilation. The changes experienced make women build new meanings and change the perception of themselves and their social environment. From the interaction with their inner self, occurred a reflection on relationships, the difference in their body and themselves, the functions it performs and the harm caused by the surgery. Conclusions: the participants felt like different women; the mutilation developed in concrete feelings, due the loss of the organ, and in abstract, linked to the impact of social identity and female functionality. The importance of the nurse establishing a multidimensional care, to identify the needs that go beyond the biological body is perceived. PMID:27579935

Current interest in careers in surgery and cardiothoracic surgery from the millennial generation.

Interest in cardiothoracic surgery (CTS) as a career has decreased over the past decade. Anecdotal evidence suggests that many surgeons develop an interest in CTS before medical school and even before college. This study evaluates the interest of high-school students at a magnet high school, with regard to careers in medicine, in surgery, and in CTS. A survey assessing career interests and values was conducted among junior and senior high-school students. Students were given a 1-hour presentation by a cardiothoracic (CT) surgeon on the postgraduate training process and then completed a postpresentation survey. A magnet math and science high school, the Kalamazoo Area Mathematics and Science Center. Of 128 students, 117 (91% response rate) completed the survey. Overall, 38% of students reported having a high interest in medicine; of this group, 58% reported a high interest in surgery and 36% reported having a high interest in CTS. Men were more likely than women were to have a high interest in surgery and CTS (p < 0.001). Students with at least 1 family member as a physician vs those without were more likely to be interested in medicine, surgery, and CTS and also have a higher level of concern for postgraduation debt (p < 0.01). Women were more likely than men were to have a high level of concern about postgraduation debt (p = 0.018). After a presentation by a CT surgeon, students showed no changes in interest in medicine careers but did report an increased level of knowledge about the process of becoming a CT surgeon, going from 31% to 72%. There exists a large interest in both surgery and CTS at the high-school level, but there may be a need for more active outreach to maintain and foster their interest in surgery and CTS through undergraduate and medical school.

Surgical robotics was first utilized to facilitate neurosurgical biopsies in 1985, and it has since found application in orthopedics, urology, gynecology, and cardiothoracic, general, and vascular surgery. Surgical assistance systems provide intelligent, versatile tools that augment the physician's ability to treat patients by eliminating hand tremor and enabling dexterous operation inside the patient's body. Surgical robotics systems have enabled surgeons to treat otherwise untreatable conditions while also reducing morbidity and error rates, shortening operative times, reducing radiation exposure, and improving overall workflow. These capabilities have begun to be realized in two important realms of aortic vascular surgery, namely, flexible robotics for exclusion of complex aortic aneurysms using branched endografts, and robot-assisted laparoscopic aortic surgery for occlusive and aneurysmal disease.

Fluorescence-Guided Surgery

Surgical resection of cancer remains an important treatment modality. Despite advances in preoperative imaging, surgery itself is primarily guided by the surgeon’s ability to locate pathology with conventional white light imaging. Fluorescence-guided surgery (FGS) can be used to define tumor location and margins during the procedure. Intraoperative visualization of tumors may not only allow more complete resections but also improve safety by avoiding unnecessary damage to normal tissue which can also reduce operative time and decrease the need for second-look surgeries. A number of new FGS imaging probes have recently been developed, complementing a small but useful number of existing probes. In this review, we describe current and new fluorescent probes that may assist FGS. PMID:29312886

To compare the surgical outcomes of simultaneous penetrating keratoplasty and cataract surgery with those of sequential surgery. Thirty-nine eyes of 39 patients scheduled for simultaneous keratoplasty and cataract surgery and 23 eyes of 23 patients scheduled for sequential keratoplasty and secondary phacoemulsification surgery were recruited. Refractive error, regular and irregular corneal astigmatism determined by Fourier analysis, and endothelial cell loss were studied at 1 week and 3, 6, and 12 months after combined surgery in the simultaneous surgery group or after subsequent phacoemulsification surgery in the sequential surgery group. At 3 and more months after surgery, mean refractive error was significantly greater in the simultaneous surgery group than in the sequential surgery group, although no difference was seen at 1 week. The refractive error at 12 months was within 2 D of that targeted in 15 eyes (39%) in the simultaneous surgery group and within 2 D in 16 eyes (70%) in the sequential surgery group; the incidence was significantly greater in the sequential group (P = 0.0344). The regular and irregular astigmatism was not significantly different between the groups at 3 and more months after surgery. No significant difference was also found in the percentage of endothelial cell loss between the groups. Although corneal astigmatism and endothelial cell loss were not different, refractive error from target refraction was greater after simultaneous keratoplasty and cataract surgery than after sequential surgery, indicating a better outcome after sequential surgery than after simultaneous surgery.

Public perception of Plastic Surgery is strongly influenced by the media and may not reflect the broad scope of work within the speciality. The aim of this study was to provide an assessment of the general public's perception of plastic surgical practice and to report the perceived importance of Plastic Surgery relative to other specialities working within a large tertiary referral centre. 899 members of the public who attended our Emergency Department completed a questionnaire where they matched eight surgical specialities with 30 operative procedures and ranked the importance of 30 different hospital specialities using a Likert scale. The majority of respondents correctly identified plastic surgeons as performing each of the cosmetic procedures listed (abdominoplasty 63.7%; breast augmentation 59.1%; facelift 61.35%; liposuction 59.7%). Plastic Surgery was identified as the primary speciality involved in breast reconstruction (49.3%) and burns surgery (43.0%). There was poor understanding of the role of plastic surgeons in hand surgery, with only 4.7% of respondents attributing tendon repair to plastic surgeons. Plastic Surgery ranked lowest of 30 specialities in terms of importance in providing care for patients within the hospital. Plastic Surgery is often misunderstood within the wider community and misconceptions reflect the influence of the media in highlighting certain aspects of the speciality. It behoves our professional organisations to highlight the importance of Plastic and Reconstructive Surgery within major tertiary referral centres.

Gastrointestinal robot-assisted surgery. A current perspective.

PubMed

Lunca, Sorinel; Bouras, George; Stanescu, Alexandru Calin

2005-12-01

Minimally invasive techniques have revolutionized operative surgery. Computer aided surgery and robotic surgical systems strive to improve further on currently available minimally invasive surgery and open new horizons. Only several centers are currently using surgical robots and publishing data. In gastrointestinal surgery, robotic surgery is applied to a wide range of procedures, but is still in its infancy. Cholecystectomy, Nissen fundoplication and Heller myotomy are among the most frequently performed operations. The ZEUS (Computer Motion, Goleta, CA) and the da Vinci (Intuitive Surgical, Mountain View, CA) surgical systems are today the most advanced robotic systems used in gastrointestinal surgery. Most studies reported that robotic gastrointestinal surgery is feasible and safe, provides improved dexterity, better visualization, reduced fatigue and high levels of precision when compared to conventional laparoscopic surgery. Its main drawbacks are the absence of force feedback and extremely high costs. At this moment there are no reports to clearly demonstrate the superiority of robotics over conventional laparoscopic surgery. Further research and more prospective randomized trials are needed to better define the optimal application of this new technology in gastrointestinal surgery.

Overview of refractive surgery.

Patients with myopia, hyperopia and astigmatism can now reduce or eliminate their dependence on contact lenses and eyeglasses through refractive surgery that includes radial keratotomy (RK), photorefractive keratectomy (PRK), laser-assisted in situ keratomileusis (LASIK), laser thermal keratoplasty (LTK) and intrastromal corneal rings (ICR). Since the approval of the excimer laser in 1995, the popularity of RK has declined because of the superior outcomes from PRK and LASIK. In patients with low-to-moderate myopia, PRK produces stable and predictable results with an excellent safety profile. LASIK is also efficacious, predictable and safe, with the additional advantages of rapid vision recovery and minimal pain. LASIK has rapidly become the most widely performed refractive surgery, with high patient and surgeon satisfaction. Noncontact Holium: YAG LTK provides satisfactory correction in patients with low hyperopia. ICR offers patients with low myopia the potential advantage of removal if the vision outcome is unsatisfactory. Despite the current widespread advertising and media attention about laser refractive surgery, not all patients are good candidates for this surgery. Family physicians should be familiar with the different refractive surgeries and their potential complications.

We analyzed the content, quality, and accuracy of information provided on hospital web sites about robotic gynecologic surgery. An analysis of hospitals with more than 200 beds from a selection of states was performed. Hospital web sites were analyzed for the content and quality of data regarding robotic-assisted surgery. Among 432 hospitals, the web sites of 192 (44.4%) contained marketing for robotic gynecologic surgery. Stock images (64.1%) and text (24.0%) derived from the robot manufacturer were frequent. Although most sites reported improved perioperative outcomes, limitations of robotics including cost, complications, and operative time were discussed only 3.7%, 1.6%, and 3.7% of the time, respectively. Only 47.9% of the web sites described a comparison group. Marketing of robotic gynecologic surgery is widespread. Much of the content is not based on high-quality data, fails to present alternative procedures, and relies on stock text and images. Copyright © 2012 Mosby, Inc. All rights reserved.

Pregnancy after bariatric surgery has some peculiarities related to obesity, type of surgery, amount of weight loss, time elapsed from the surgery and adherence to medical prescriptions. Pregnant woman is at risk of nutritional deficiencies and it is unclear whether there is an increased incidence of intestinal complications during pregnancy after bariatric surgery and whether this kind of complications are more frequent during cesarean section. The fetus is at high risk of prematurity and fetal growth restriction, but they seem not at increased risk of birth defects (DTN) except in individual cases of folic acid deficiency (DTN) or vitamin K defect (similar abnormalities in patients receiving oral anticoagulants). In addition, the incidence of gestational diabetes and hypertension results to be decreased. Other postnatal outcomes from possible epigenetic modifications need to be evaluated in the long-term postnatal follow-up.

The association between thymic tumors and other intrathoracic or extrathoracic neoplasms is relatively rare; the synchronous occurrence of thymoma and bronchoalveolar carcinoma of the lung has never been described so far. A huge B3 cystic thymoma was found at thoracotomy to be associated with stage IV bronchoalveolar carcinoma (intraparenchymal and pleural metastases). The thymic tumor was completely resected; lung cancer was biopsied only for diagnosis and staging purposes. After an uneventful postoperative course the patient underwent chemotherapy; she is still alive and well one year after surgery.

2001-04-01

Two children who had undergone a transappendicular urinary diversion (type Mitrofanoff) developed bladder rupture, one following abdominal trauma, 4 months after the operation and the other following traumatic self-catheterization at 4 years. The clinical history and standard radiological examinations (ultrasonography, cystography) confirmed the diagnosis of urinary peritonitis. Emergency surgical repair was possible in both cases with an uneventful postoperative course. This serious and rare complication requires emergency surgery and justifies rigorous selection of children suitable for this type of diversion giving preference to increased bladder neck resistance over bladder neck closure.

2012-06-01

There have been few attempts to identify classic papers within the hand surgery literature. This study used citation analysis to identify and characterize the top 50 highly cited hand surgery articles published in six peer-reviewed journals. The 50 most highly cited hand surgery articles were identified in the Journal of Bone and Joint Surgery (JBJS) American, JBJS British, Plastic and Reconstructive Surgery, Journal of Hand Surgery (JHS) American, JHS British/European, and Hand. Articles were evaluated for citations per year, surgical/anatomical topic, and type of study. Clinical studies were further sub-categorized by level of evidence. The distribution of topics was compared with all indexed hand surgery articles. The educational relevance was assessed via comparison with lists of "classic" papers. The most common subjects were distal radius fracture, carpal tunnel syndrome, and flexor tendon repair. There was moderate correlation between the distribution of these topics and all indexed hand surgery articles (rho = 0.71). There were 31 clinical studies, of which 16 were therapeutic, ten were prognostic, and five were diagnostic. These articles assessed the outcomes of an intervention, described an anatomical/functional observation, introduced an innovation, presented a discovery/classification, or validated a questionnaire. There were only three randomized trials. Using citations per year to control for the influence of time since publication, 36 articles were consistently highly cited. Twenty-three articles were on Stern's Selected Readings in Hand Surgery, considered important in education. The top 50 highly cited articles in hand surgery reflect the most common clinical, scientific, and educational efforts of the field.

The aim of this study was to describe changes over time in the indications and outcomes of cataract surgery and to discuss optimal timing for the surgery. Database study. Patients who had undergone cataract extraction in the Netherlands, Sweden, or Malaysia from 2008 through 2012. We analyzed preoperative, surgical, and postoperative data from 2 databases: the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) and the Malaysian National Cataract Registry. The EUREQUO contains complete data from the national cataract registries in the Netherlands and Sweden. Preoperative and postoperative corrected distance visual acuity, preoperative ocular comorbidity in the surgery eye, and capsule complications during surgery. There were substantial differences in indication for surgery between the 3 national data sets. The percentage of eyes with a preoperative best-corrected visual acuity of 20/200 or worse varied from 7.1% to 72%. In all 3 data sets, the visual thresholds for cataract surgery decreased over time by 6% to 28% of the baseline values. The frequency of capsule complications varied between the 3 data sets, from 1.1% to 3.7% in 2008 and from 0.6% to 2.7% in 2012. An increasing postoperative visual acuity was also seen for all 3 data sets. A high frequency of capsule complication was related significantly to poor preoperative visual acuity, and a high frequency of decreased visual acuity after surgery was related significantly to excellent preoperative visual acuity. The 5-year trend in all 3 national data sets showed decreasing visual thresholds for surgery, decreasing surgical complication rates, and increasing visual outcomes regardless of the initial preoperative visual level. Cataract surgery on eyes with poor preoperative visual acuity was related to surgical complications, and cataract surgery on eyes with excellent preoperative visual acuity was related to adverse visual results.

2013-08-05

We present a new model of guided surgery, exclusively using computer assistance, from the preoperative planning of osteotomies to the actual surgery with the aid of stereolithographic cutting guides and osteosynthetic miniplates designed and made preoperatively, using custom-made titanium miniplates thanks to direct metal laser sintering. We describe the principles that guide the designing and industrial manufacturing of this new type of osteosynthesis miniplates. The surgical procedure is described step-by-step using several representative cases of dento-maxillofacial dysmorphosis. The encouraging short-term results demonstrate the wide range of application of this new technology for cranio-maxillofacial surgery, whatever the type of osteotomy performed, and for plastic reconstructive surgery.

The obesity epidemic is associated with a rise in coronary surgeries because obesity is a risk factor for coronary artery disease. Bariatric surgery is linked to improvement in cardiovascular co-morbidities and left ventricular function. No studies have investigated survival advantage in postoperative bariatric patients after coronary surgery. To determine if there is a benefit after coronary surgery in patients who have previously undergone bariatric surgery. National Inpatient Sample. We performed a retrospective, cross-sectional analysis of the National Inpatient Sample database from 2003 to 2010. We selected bariatric surgical patients who later underwent coronary surgery (n = 257). A comparison of postoperative complications and mortality after coronary surgery were compared with controls (n = 1442) using χ 2 tests, linear regression analysis, and multivariate logistical regression models. A subset population was identified as having undergone coronary surgery (n = 1699); of this population, 257 patients had previously undergone bariatric surgery. They were compared with 1442 controls. The majority was male (67.2%), white (82.6%), and treated in an urban environment (96.8%). Patients with bariatric surgery assumed the risk of postoperative complications after coronary surgery that was associated with their new body mass index (BMI) (BMI<25 kg/m 2 : odds ratio (OR) 1.01, 95% CI .76-1.34, P = .94; BMI 25 to<35 kg/m 2 : OR .20, 95% CI .02- 2 .16, P = .19; BMI≥35 kg/m 2 : OR>999.9, 95% CI .18 to>999.9, P = .07). Length of stay was significantly longer in postbariatric patients (BMI<25, OR 1.62, 95% CI 1.14-2.30, P = .007). Postoperative bariatric patients have a return to baseline risk of morbidity and mortality after coronary surgery. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc.

Telemedicine is the use of electronic digital signals to transfer information from one site to another. With the advent of a telepresence operative system and development of remote robotic arms to hold and manoeuvre the laparoscope, telemedicine is finding its role in surgery, especially laparoscopic surgery. CLINICAL FEATURES AND TREATMENT: We report two successful cases of laparoscopic surgery--radical nephrectomy and varicocelectomy for a 3-cm renal tumour and for bilateral varicoceles causing pain, where a less experienced laparoscopic surgeon in Singapore was telementored by an experienced laparoscopic surgeon located remotely in the United States. Both patients recovered uneventfully and returned home on postoperative day 4 and on the day of surgery, respectively. This study demonstrates that telementored laparoscopic systems are feasible and safe, between countries halfway across the world. As the Internet expands in utility and the cost of higher bandwidth telecommunication lines decreases, even to remote countries, telementoring systems will become more affordable and may potentially pave the way for advanced surgical and laparoscopic applications and training for the future.

2003-10-01

A 78-year-old male, observed for bronchial asthma, underwent two emergency operations within eight days. The first operation was performed under general anesthesia with tracheal intubation. Anesthesia was maintained by sevoflurane-oxygen and continuous infusion of propofol in combination with epidural injection of lidocaine. During the operation, respiratory sound was almost clear. But wheezing occurred as he awoke after discontinuation of the anesthetics. He needed ventilatory support for three days for status asthmatics. The second operation was performed under continuous spinal anesthesia using hypobaric tetracaine and hyperbaric bupivacaine. No ventilatory support was necessary after the operation and he was discharged uneventfully.

Laser Refractive Surgery

NASA Astrophysics Data System (ADS)

Wynne, James

Refractive surgery has its roots in corneal transplant surgery, first performed in 1905, where the damaged or diseased cornea of a living individual is replaced by donated corneal tissue taken from a recently deceased individual. Since the cornea has no blood supply, there is no danger of organ rejection. Recognizing the exceptional healing power of corneal tissue, ophthalmologists began to explore methods of reshaping the cornea to improve the visual acuity of patients suffering from myopia, hyperopia, and astigmatism. In 1964, a procedure known as keratomileusis was introduced. In 1974, radial keratotomy (RK) was introduced. In 1981, excimer laser surgery was discovered by the speaker and his IBM Research colleagues. In 1983, the excimer laser was used to create clean, precise incisions in the cornea of enucleated calf eyes, derived from slaughter, launching the era of laser refractive surgery, with more precise and safer techniques to correct myopia, hyperopia, and stigmatism. This talk will describe the widely practiced surgical procedures known as photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK), which have improved the visual acuity of more than 35 million people. Most patients undergoing PRK or LASIK end up with uncorrected vision better than 20/20. In 2007, development commenced on a new procedure known as small incision lenticule extraction (SMILE), employing a femtosecond laser and no excimer laser. SMILE is promoted as minimally invasive and combining the advantages of PRK and LASIK. However, long term stability of visual acuity following SMILE surgery is yet to be determined.

Nowadays, performing orthognathic surgery involves the TMJ in three different occasions: (1) TMJ disorders potentially responsible for dento-maxillary dysmorphosis, (2) effects of orthognathic surgery on TMJs, and (3) condylar positioning methods in orthognathic surgery. These three chapters are developed in order to focus on the close relationships between TMJ and orthognathic surgery. Some perspectives close this article. Copyright © 2016 Elsevier Masson SAS.

The evolution of robotic general surgery.

Wilson, E B

2009-01-01

Surgical robotics in general surgery has a relatively short but very interesting evolution. Just as minimally invasive and laparoscopic techniques have radically changed general surgery and fractionated it into subspecialization, robotic technology is likely to repeat the process of fractionation even further. Though it appears that robotics is growing more quickly in other specialties, the changes digital platforms are causing in the general surgical arena are likely to permanently alter general surgery. This review examines the evolution of robotics in minimally invasive general surgery looking forward to a time where robotics platforms will be fundamental to elective general surgery. Learning curves and adoption techniques are explored. Foregut, hepatobiliary, endocrine, colorectal, and bariatric surgery will be examined as growth areas for robotics, as well as revealing the current uses of this technology.

Providing timely access to surgery is crucial for patients with high acuity diseases like cancer. We present a methodological framework to make efficient use of scarce resources including surgeons, operating rooms, and clinic appointment slots with a goal of coordinating clinic and surgery appointments so that patients with different acuity levels can see a surgeon in the clinic and schedule their surgery within a maximum wait time target that is clinically safe for them. We propose six heuristic scheduling policies with two underlying ideas behind them: (1) proactively book a tentative surgery day along with the clinic appointment at the time an appointment request is received, and (2) intelligently space out clinic and surgery appointments such that if the patient does not need his/her surgery appointment there is sufficient time to offer it to another patient. A 2-stage stochastic discrete-event simulation approach is employed to evaluate the six scheduling policies. In the first stage of the simulation, the heuristic policies are compared in terms of the average operating room (OR) overtime per day. The second stage involves fine-tuning the most-effective policy. A case study of the division of colorectal surgery (CRS) at the Mayo Clinic confirms that all six policies outperform the current scheduling protocol by a large margin. Numerical results demonstrate that the final policy, which we refer to as Coordinated Appointment Scheduling Policy considering Indication and Resources (CASPIR), performs 52% better than the current scheduling policy in terms of the average OR overtime per day under the same access service level. In conclusion, surgical divisions desiring stratified patient urgency classes should consider using scheduling policies that take the surgical availability of surgeons, patients' demographics and indication of disease into consideration when scheduling a clinic consultation appointment.

Surgical quality registers provide tools to measure and improve the outcome of surgery. International register collaboration creates an opportunity to assess and critically evaluate national practices, and increases the size of available datasets. Even though millions of yearly tonsillectomies and tonsillotomies are performed worldwide, clinical practices are variable and inconsistency of evidence regarding the best clinical practice exists. The need for quality improvement actions is evident. We aimed to systematically investigate the existing tonsil surgery quality registers found in the literature, and to provide a thorough presentation of the planned Nordic Tonsil Surgery Register Collaboration. A systematic literature search of MEDLINE and EMBASE databases (from January 1990 to December 2016) was conducted to identify registers, databases, quality improvement programs or comprehensive audit programs addressing tonsil surgery. We identified two active registers and three completed audit programs focusing on tonsil surgery quality registration. Recorded variables were fairly similar, but considerable variation in coverage, number of operations included and length of time period for inclusion was discovered. Considering tonsillectomies and tonsillotomies being among the most commonly performed surgical procedures in otorhinolaryngology, it is surprising that only two active registers could be identified. We present a Nordic Tonsil Surgery Register Collaboration-an international tonsil surgery quality register project aiming to provide accurate benchmarks and enhance the quality of tonsil surgery in Denmark, Finland, Norway and Sweden.

Multidisciplinary pre-admission patient education is commonly recommended for elective surgery patients, and may involve the provision of written information and presentations from the health team. However, the occupational therapy role with elective sternotomy patients in our setting is confined to the post-operative period. We aimed to evaluate cardiac surgery patients' perception of the effectiveness and timing of pre-admission multidisciplinary written information and post-operative verbal education provided by occupational therapy. This cross-sectional study involved a written survey, which was posted to 375 people who had undergone cardiac surgery in 2009-2010. Questions were designed to elicit patient perceptions of both pre-operative written information and post-operative education relating to post-operative precautions and return to activity received from occupational therapy. There were 118 surveys returned equalling a 31.4% response rate. Eighty-nine per cent of respondents recalled receiving and reading the pre-surgery information booklet, and this was significantly correlated with feeling prepared for the post-operative experience and adherence with precautions (P < 0.0001). Exactly 30.4% of respondents stated that they experienced stress and anxiety in relation to post-operative expectations, and 47.3% felt the information provided in the occupational therapy education sessions would have been more beneficial for their understanding and coping if provided prior to surgery. Multidisciplinary written pre-surgery education appears to be providing patients with a good understanding of what to expect following surgery. The results suggest that pre-operative verbal education from occupational therapy would assist in reducing anxiety in a subgroup of patients. © 2013 Occupational Therapy Australia.

To review data on malpractice claims related to refractive surgery to identify common allegations and injuries and financial outcomes. The WestlawNext database was reviewed for all malpractice lawsuits/settlements related to refractive eye surgery. Data evaluated included patient demographics, type of operation performed, plaintiff allegation, nature of injury, and litigation outcomes. A total of 167 cases met the inclusion criteria, of which 108 cases (64.7%) were found to be favorable and 59 cases (35.3%) unfavorable to the defendant. A total of 141 cases were tried by a jury with 108 cases (76.4%) favorable and 33 cases (23.6%) unfavorable to the defendant. Laser in situ keratomileusis was performed in 127 cases (76%). The most common allegations were negligence in treatment or surgery in 127 cases (76%) and lack of informed consent in 83 cases (49.7%). For all cases, the need for future surgery (P = 0.0001) and surgery resulting in keratoconus (P = 0.05) were more likely to favor the plaintiff. In jury verdict decisions, cases in which failure to diagnose a preoperative condition was alleged favored the defendant (P = 0.03), whereas machine malfunction (P = 0.05) favored the plaintiff. After adjustment for inflation, the overall mean award was $1,287,872. Jury verdicts and settlements led to mean awards of $1,604,801 and $826,883, respectively. Malpractice litigation in refractive surgery tends to favor the defendant. However, large awards and settlements were given in cases that were favorable to the plaintiff. The need for future surgery and surgery leading to keratoconus increased the chance of an unfavorable outcome.

Trends in pediatric epilepsy surgery.

Shah, Ritesh; Botre, Abhijit; Udani, Vrajesh

2015-03-01

Epilepsy surgery has become an accepted treatment for drug resistant epilepsy in infants and children. It has gained ground in India over the last decade. Certain epilepsy surgically remediable syndromes have been delineated and should be offered surgery earlier rather than later, especially if cognitive/behavioral development is being compromised. Advances in imaging, particularly in MRI has helped identify surgical candidates. Pre-surgical evaluation includes clinical assessment, structural and functional imaging, inter-ictal EEG, simultaneous video -EEG, with analysis of seizure semiology and ictal EEG and other optional investigations like neuropsychology and other newer imaging techniques. If data are concordant resective surgery is offered, keeping in mind preservation of eloquent cortical areas subserving motor, language and visual functions. In case of discordant data or non-lesional MRI, invasive EEG maybe useful using a two-stage approach. With multi-focal / generalized disease, palliative surgery like corpus callosotomy and vagal nerve stimulation maybe useful. A good outcome is seen in about 2/3rd of patients undergoing resective surgery with a low morbidity and mortality. This review outlines important learning aspects of pediatric epilepsy surgery for the general pediatrician.

The surgical training at Bassett is naturally broader than in many university settings, with a survey showing that nearly 70% of graduates who practice general surgery remain in a rurally designated area. Rural surgery experience falls into 3 categories: undergraduate, graduate, and postgraduate. The general surgery training program has no competing fellowships or subspecialty residencies; residents get significant experience with endoscopy; ear, nose, and throat; plastic and hand surgery; and obstetrics and gynecology. The rural setting lifestyle is valued by the students, residents, and fellows alike. It provides an ideal setting for recognizing the specific nuances of small-town American life, with a high-quality education and surgical experience.

A 76-year-old man was admitted to our hospital for treatment of gastric tube cancer(cT2N0M0, cStage II A)detected by a screening upper gastrointestinal endoscopy. Seven years previously, he had undergone subtotal esophagectomy for esophageal cancer with gastric pull-up via the retrosternal route. At that time, he experienced cardiopulmonary arrest due to ventric- ular tachycardia. He was in a state of poor nutrition(BMI 15 kg/m2). Therefore, reducing operative stress as much as possible, minimizing complications after surgery, and aiming for a satisfactory postoperative course are all important goals. Based on his past history, we performed distal gastrectomy(resection of the distal part of the gastric tube)without excision of the right gastroepiploic artery. The postoperative course was uneventful. He was discharged 40 days after surgery. By considering the risks of surgery due to cardiac dysfunction and malnutrition, we were able to provide effective and safe therapy for the patient.

The purpose of this study was to report the incidence of deep venous thrombosis (DVT) among cardiac and vascular surgery patients, compared with general surgery. The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent surgical procedures from 2005 to 2010. Patients who developed DVT within 30 days of an operation were identified. The incidence of DVT was compared among vascular, general, and cardiac surgery patients. Risk factors for developing postoperative DVT were identified and compared among these patients. Of total 2,669,772 patients underwent surgical operations in the period between 2005 and 2010. Of all the patients, 18,670 patients (0.69%) developed DVT. The incidence of DVT among different surgical specialties was cardiac surgery (2%), vascular surgery (0.99%), and general surgery (0.66%). The odds ratio for developing DVT was 1.5 for vascular surgery patients and 3 for cardiac surgery patients, when compared with general surgery patients (P < 0.001). The odds ratio for developing DVT after cardiac surgery was 2, when compared with vascular surgery (P < 0.001). The incidence of DVT is higher among vascular and cardiac surgery patients as compared with that of general surgery patients. Intraoperative anticoagulation does not prevent the occurrence of DVT in the postoperative period. These patients should receive DVT prophylaxis in the perioperative period, similar to other surgical patients according to evidence-based guidelines. Copyright © 2015 Elsevier Inc.

The low incidence rate of adrenocortical carcinoma (ACC) requires a multidisciplinary approach in which surgery plays an essential role because complete resection of the primary tumor is the only chance of cure. To improve patient care, insight into operative results within the ACC population is essential. In 2007, a Dutch Adrenal Network Registry was created covering care and outcome of patients treated for ACC in the Netherlands since 1965. Using this database, we performed a study (1) to gain insight into surgical performance in the Netherlands and (2) to compare operative data with international literature. Data on patients treated from 1965 until January 2008 were studied. The following data were collected: age, gender, functionality of the tumor, stage at diagnosis, operative procedure, completeness of surgery, disease recurrence, adjuvant mitotane therapy, and recurrence-free and overall survival (OS). A total of 175 patients were studied, of whom 149 underwent surgery. Patients with complete resection had significantly longer OS times than patients with incomplete resection (P = .010). Patients operated on in a Dutch Adrenal Network center had significantly longer duration of OS in both univariate (P = .011) and multivariate analysis (P = .014). A significantly greater OS was observed for operated stage IV patients compared with nonoperated patients (P = .002). Our data suggest the relevance of national cooperation and centralized surgery in ACC. For selected patients with stage IV disease, surgery can be beneficial in extending survival. On the basis of the retrospective analysis, operative ACC in the Netherlands can and will be improved. Copyright © 2012. Published by Mosby, Inc.

Trocar-site hernia is an uncommon but serious complication after laparoscopic surgery as it frequently requires surgical intervention. We describe a 75-year-old man with Gleason score 4 + 3, clinical stage T1c prostate adenocarcinoma who underwent an uneventful robot-assisted transperitoneal laparoscopic radical prostatectomy. On post-operative day four, he developed symptoms of small bowel obstruction due to herniation and incarceration of the small bowels in a Spigelian-type hernia at the left lower quadrant 8-mm trocar site. Surgical exploration was performed via a mini-laparotomy to reduce the bowel and repair the fascial layers. A literature search was performed to review other cases of trocar-site hernia through the 8-mm robotic port after robot-assisted surgery and the suggested methods of prevention.

To describe a case that developed "interface fluid syndrome" after previous laser in situ keratomileusis (LASIK) because of Fuchs endothelial dystrophy (FED), which was reversed by Descemet membrane endothelial keratoplasty (DMEK). A 58-year-old male patient presented with bilateral visual impairment owing to FED and visually significant cataract. Cataract surgery was carried out in both eyes followed by DMEK in his left eye. After cataract surgery, visual acuity did not improve sufficiently because corneal thickness increased and a fine cleft with interface fluid developed between the LASIK-flap and the residual stromal bed. After uneventful DMEK in his left eye, the fluid resolved within a week and visual acuity improved rapidly. This case demonstrates that "interface fluid syndrome" after LASIK caused by concomitant endothelial dysfunction may be reversed by DMEK allowing fast visual recovery.

Phacoemulsification with in-the-bag intraocular lens (IOL) implantation is the standard procedure for cataract surgery. Pigment dispersion and uveitis can result when an IOL is placed in the sulcus. We report a case of a 64-year-old woman, with pigmentary glaucoma, who developed recurrent uveitis following uneventful cataract surgery and an in-the-bag hydrophobic acrylic IOL implant. Recurrent uveitis did not subside despite use of topical steroids over 3 months. Dilated examination revealed capsulophimosis with anterior dislocation of the IOL haptic. The mechanical trauma to the iris due to the displaced haptic was implicated as the cause of recurrent uveitis, which completely resolved after capsular excision and IOL repositioning. This case illustrates a rare cause of recurrent uveitis due to IOL haptic dislocation following severe capsulophimosis. 2016 BMJ Publishing Group Ltd.

The first congress was during October 1953 and the first president as Maurice Aubry. The first secretary was Daniel Morel Fatio. The symposiums were after about three of four times each year and the thematic subjects were initially according the reconstructive surgery. The review "Annales de chirurgie plastique" was free in 1956. The members of the Society were about 30 initially, but their plastic surgery in the big hospitals at Paris and other big towns in France. The "specialty" of plastic surgery was created in 1971. On "syndicate", one French board of plastic reconstructive and aesthetic surgery, the increasing of departments of plastic surgery were the front of increasing of the plastic surgery in French and of the number of the French Society of Plastic Reconstructive surgery (580 in 2003). The French Society organized the International Congress of Plastic Surgery in 1975.

Vitreoretinal surgery has benefited from great advances opening the opportunity for outpatient management. We report on the 6-month experience of outpatient surgery for vitreoretinal diseases. From November 2007 to April 2008, 270 patients benefited from a vitreoretinal surgery, with 173 retinal detachments, 63 epiretinal membranes, and 34 other procedures. Only 8.5% (n=23) of the patients had to stay at the hospital one or two nights. The main reasons were the distance from the hospital and surgery on a single-eye patient. The questionnaire given after the surgery showed that almost all the patients were satisfied with the outpatient setting. In contrast, the financial results showed a loss of income of around 400,000 euros due to the low level of payment of outpatient surgery in France by the national health insurance system. Vitreoretinal surgery can be achieved in outpatient surgery with an improvement in the information given to the patients and the overall organization of the hospitalization. However, the current income provided with vitreoretinal outpatient surgery is highly disadvantageous in France, preventing this method from being generalized.

To compare visual acuity outcomes, vision-related quality of life, and complications related to cataract surgery in eyes with and without glaucoma. Retrospective cohort study. Cataract surgery outcomes in cases with and without glaucoma from the Veterans Affairs Ophthalmic Surgical Outcomes Data Project were compared. We identified 608 glaucoma cases and 4306 controls undergoing planned cataract surgery alone. After adjusting for age, pseudoexfoliation, small pupil, prior ocular surgery, and anterior chamber depth, we found that glaucoma cases were more likely to have posterior capsular tear with vitrectomy (odds ratio [OR] 1.8, P = .03) and sulcus intraocular lens placement (OR 1.65, P = .03) during cataract surgery. Glaucoma cases were more likely to have postoperative inflammation (OR 1.73, P < .0001), prolonged elevated intraocular pressure (OR 2.96, P = .0003), and additional surgery within 30 days (OR 1.92, P = .03). Mean best-corrected visual acuity (BCVA) and Visual Function Questionnaire (VFQ) scores significantly improved after cataract surgery in both groups (P < .0001), but there were larger improvements in BCVA (P = .01) and VFQ composite scores (P < .0001) in the nonglaucoma vs the glaucoma group. A total of 3621 nonglaucoma cases (94.1%) had postoperative BCVA 20/40 or better, compared to 466 glaucoma cases (89.6%) (P = .0003). Eyes with glaucoma are at increased risk for complications and have more modest visual outcomes after cataract surgery compared to eyes without glaucoma. Despite this, glaucoma patients still experience significant improvement in vision-related outcomes after cataract extraction. Further study is needed to explore potential factors that influence cataract surgery outcomes in glaucomatous eyes. Published by Elsevier Inc.

Robotic colorectal surgery is an emerging field and may offer a solution to some of the difficulties inherent to conventional laparoscopic surgery. The aim of this review is to provide a comprehensive and critical analysis of the available literature on the use of robotic technology in colorectal surgery. Studies reporting outcomes of robotic colorectal surgery were identified by systematic searches of electronic databases. Outcomes examined included operating time, length of stay, blood loss, complications, cost, oncological outcome, and conversion rates. Seventeen Studies (nine case series, seven comparative studies, one randomized controlled trial) describing 288 procedures were identified and reviewed. Study heterogeneity precluded a meta-analysis of the data. Robotic procedures tend to take longer and cost more, but may reduce the length of stay, blood loss, and conversion rates. Complication profiles and short-term oncological outcomes are similar to laparoscopic surgery. Robotic colorectal surgery is a promising field and may provide a powerful additional tool for optimal management of more challenging pathology, including rectal cancer. Further studies are required to better define its role. © 2010 The Authors. Colorectal Disease © 2010 The Association of Coloproctology of Great Britain and Ireland.

Orthopedic and plastic surgery residents receive unique training yet often compete for similar hand surgery fellowships. This study compared didactic hand surgery training during orthopedic and plastic surgery residency. The Plastic Surgery In-Service Training Exam and Orthopaedic In-Training Examination were analyzed for hand content for the years 2009 to 2013. Topics were categorized with the content outline for the Surgery of the Hand Examination. Differences were elucidated by means of Fisher's exact test. Relative to the Orthopaedic In-Training Examination, the Plastic Surgery In-Service Training Exam had greater hand representation (20.3 percent versus 8.1 percent; p < 0.001) with more annual hand questions (40 ± 3 versus 24 ± 2; p < 0.001). The Plastic Surgery Exam questions had more words, were less often level I-recall type, and were less often image-based. The questions focused more on finger and hand/palm anatomy, whereas the Orthopaedic examination was more wrist-focused. The Plastic Surgery Exam emphasized wound management and muscle/tendon injuries, but underemphasized fractures/dislocations. References differed, but Journal of Hand Surgery (American Volume) and Green's Operative Hand Surgery were common on both examinations. The Plastic Surgery Exam had a greater publication lag for journal references (10.7 ± 0.5 years versus 9.0 ± 0.6; p = 0.035). Differences in didactic hand surgery training are elucidated for plastic surgery and orthopedic residents. Deficiencies in the Plastic Surgery In-Service Training Exam hand curriculum relative to the Orthopaedic In-Training Examination may underprepare plastic surgeons for the Surgery of the Hand Examination. These data may assist future modifications to hand surgery training in the United States.

Sex reassignment surgery (SRS) has proved an effective intervention for patients with gender identity disorder. However, misdiagnosed patients sometimes regret their decision and request reversal surgery. This review is based on our experience with seven patients who regretted their decision to undergo male-to-female SRS. To analyze retrospectively seven patients who underwent reversal surgery after regretting their decision to undergo male-to-female SRS elsewhere. From November 2010 through November 2014, seven men 33 to 53 years old with previous male-to-female SRS underwent reversal phalloplasty. Preoperatively, they were examined by three independent psychiatrists. Surgery included three steps: removal of female genitalia with scrotoplasty and urethral lengthening, total phalloplasty with microvascular transfer of a musculocutaneous latissimus dorsi flap, and neophallus urethroplasty with penile prosthesis implantation. Self-reported esthetic and psychosexual status after reversion surgery and International Index of Erectile Function scores for sexual health after phalloplasty and penile prosthesis implantation. Follow-up was 13 to 61 months (mean = 31 months). Good postoperative results were achieved in all patients. In four patients, all surgical steps were completed; two patients are currently waiting for penile implants; and one patient decided against the penile prosthesis. Complications were related to urethral lengthening: two fistulas and one stricture were observed. All complications were repaired by minor revision. According to patients' self-reports, all patients were pleased with the esthetic appearance of their genitalia and with their significantly improved psychological status. Reversal surgery in regretful male-to-female transsexuals after SRS represents a complex, multistage procedure with satisfactory outcomes. Further insight into the characteristics of persons who regret their decision postoperatively would facilitate better future

Cosmetic surgery in Australia: a risky business?

PubMed

Parker, Rhian

2007-08-01

Cosmetic surgery is increasing in popularity in Australia and New Zealand, as it is across other Western countries. However, there is no systematic mechanism for gathering data about cosmetic surgery, nor about the outcomes of that surgery. This column argues that the business of cosmetic surgery in Australia has questionable marketing standards, is conducted with little scrutiny or accountability and offers patients imperfect knowledge about cosmetic procedures. It also argues that while medical practitioners debate among themselves over who should carry out cosmetic procedures, little attention has been paid to questionable advertising in the industry and even less to highlighting the real risks of undergoing cosmetic surgery. While consumers are led to believe that cosmetic surgery is accessible, affordable and safe, they are sheltered from the reality of invasive and risky surgery and from the ability to clearly discern that all cosmetic procedures carry risk. While doctors continue to undertake advertising and engage in a territorial war, they fail to address the really important issues in cosmetic surgery. These are: providing real evidence about what happens in the industry, developing stringent regulations under which the industry should operate and ensuring that all patients considering cosmetic surgery are fully informed as to the risks of that surgery.

Ethical challenges in fetal surgery.

PubMed

Smajdor, Anna

2011-02-01

Fetal surgery has been practised for some decades now. However, it remains a highly complex area, both medically and ethically. This paper shows how the routine use of ultrasound has been a catalyst for fetal surgery, in creating new needs and new incentives for intervention. Some of the needs met by fetal surgery are those of parents and clinicians who experience stress while waiting for the birth of a fetus with known anomalies. The paper suggests that the role of technology and visualisation techniques in creating and meeting such new needs is ethically problematic. It then addresses the idea that fetal surgery should be restricted to interventions that are life-saving for the fetus, arguing that this restriction is unduly paternalistic. Fetal surgery poses challenges for an autonomy-based system of ethics. However, it is risky to circumvent these challenges by restricting the choices open to pregnant women, even when these choices appear excessively altruistic.

Variability in spine surgery procedures performed during orthopaedic and neurological surgery residency training: an analysis of ACGME case log data.

Current spine surgeon training in the United States consists of either an orthopaedic or neurological surgery residency, followed by an optional spine surgery fellowship. Resident spine surgery procedure volume may vary between and within specialties. The Accreditation Council for Graduate Medical Education surgical case logs for graduating orthopaedic surgery and neurosurgery residents from 2009 to 2012 were examined and were compared for spine surgery resident experience. The average number of reported spine surgery procedures performed during residency was 160.2 spine surgery procedures performed by orthopaedic surgery residents and 375.0 procedures performed by neurosurgery residents; the mean difference of 214.8 procedures (95% confidence interval, 196.3 to 231.7 procedures) was significant (p = 0.002). From 2009 to 2012, the average total spinal surgery procedures logged by orthopaedic surgery residents increased 24.3% from 141.1 to 175.4 procedures, and those logged by neurosurgery residents increased 6.5% from 367.9 to 391.8 procedures. There was a significant difference (p < 0.002) in the average number of spinal deformity procedures between graduating orthopaedic surgery residents (9.5 procedures) and graduating neurosurgery residents (2.0 procedures). There was substantial variability in spine surgery exposure within both specialties; when comparing the top 10% and bottom 10% of 2012 graduates for spinal instrumentation or arthrodesis procedures, there was a 13.1-fold difference for orthopaedic surgery residents and an 8.3-fold difference for neurosurgery residents. Spine surgery procedure volumes in orthopaedic and neurosurgery residency training programs vary greatly both within and between specialties. Although orthopaedic surgery residents had an increase in the number of spine procedures that they performed from 2009 to 2012, they averaged less than half of the number of spine procedures performed by neurological surgery residents.

Robot assisted thyroid surgery has been the latest advance in the evolution of thyroid surgery after endoscopy assisted procedures. The advantage of a superior field vision and technical advancements of robotic technology have permitted novel remote access (trans-axillary and retro-auricular) surgical approaches. Interestingly, several remote access surgical ports using robot surgical system and endoscopic technique have been customized to avoid the social stigma of a visible scar. Current literature has displayed their various advantages in terms of post-operative outcomes; however, the associated financial burden and also additional training and expertise necessary hinder its widespread adoption into endocrine surgery practices. These approaches offer excellent cosmesis, with a shorter learning curve and reduce discomfort to surgeons operating ergonomically through a robotic console. This review aims to provide details of various remote access techniques that are being offered for thyroid resection. Though these have been reported to be safe and feasible approaches for thyroid surgery, further evaluation for their efficacy still remains. PMID:26425450

To present an economic-analysis comparison of simultaneous and sequential bilateral cataract surgery. Helsinki University Eye Hospital, Helsinki, Finland. Economic analysis. Effects were estimated from data in a study in which patients were randomized to have bilateral cataract surgery on the same day (study group) or sequentially (control group). The main clinical outcomes were corrected distance visual acuity, refraction, complications, Visual Function Index-7 (VF-7) scores, and patient-rated satisfaction with vision. Health-care costs of surgeries and preoperative and postoperative visits were estimated, including the cost of staff, equipment, material, floor space, overhead, and complications. The data were obtained from staff measurements, questionnaires, internal hospital records, and accountancy. Non-health-care costs of travel, home care, and time were estimated based on questionnaires from a random subset of patients. The main economic outcome measures were cost per VF-7 score unit change and cost per patient in simultaneous versus sequential surgery. The study comprised 520 patients (241 patients included non-health-care and time cost analyses). Surgical outcomes and patient satisfaction were similar in both groups. Simultaneous cataract surgery saved 449 Euros (€) per patient in health-care costs and €739 when travel and paid home-care costs were included. The savings added up to €849 per patient when the cost of lost working time was included. Compared with sequential bilateral cataract surgery, simultaneous bilateral cataract surgery provided comparable clinical outcomes with substantial savings in health-care and non-health-care-related costs.

The aim of this retrospective chart review of the patients who had septal surgery with or without turbinate surgery was to compare the postoperative complication rates according to the time of intranasal-splint (INS) removal. The data of 137 patients who underwent septal surgery with or without turbinate surgery at 2 different hospitals of Acıbadem Health Care Group between January 2007 and March 2009 were retrospectively evaluated. The patients who had these risk factors were eliminated, and 96 patients were included in this study. The patients were divided into 2 groups according to splint-removal time. The first group comprises patients whose nasal splints were removed in 24 hours after surgery, and the second group comprises patients whose splints were removed 5 days after the surgery. Any bleeding, septal hematoma, and synechia after pack removal were recorded. Analysis of the rate of complications was done with the χ test. Sixty-five male and 31 female patients with a mean age of 32.4 years (range, 18-57 years) were included in the study groups. Septal surgeries were performed in association with turbinate surgery in all 96 patients. These patients were divided into 2 groups. In the first group (n = 50), INSs were removed in 24 hours after surgery. In the second group (n = 46), INSs were removed 5 days after surgery. Bleeding within the first postoperative week was not recorded in both groups. Late bleeding was recorded in 2% (n = 1) of group 1 and in 2.17% (n = 1) in group 2. Septal hematoma and synechia were not recorded in none of the groups. The results were not statistically significant (P = 1). The routine use of INSs after septoplasty and removing them 24 hours after septoplasty are sufficient to avoid postoperative complications, and it minimizes postoperative discomfort.

Live surgery is an important part of surgical education, with an increase in the number of live surgery events (LSEs) at meetings despite controversy about their real educational value, risks to patient safety, and conflicts of interest. To provide a European Association of Urology (EAU) policy on LSEs to regulate their organisation during urologic meetings. The project was carried out in phases: a systematic literature review generating key questions, surveys sent to Live Surgery Panel members, and Internet- and panel-based consensus finding using the Delphi process to agree on and formulate a policy. The EAU will endorse LSEs, provided that the EAU Code of Conduct for live surgery and all organisational requirements are followed. Outcome data must be submitted to an EAU Web-based registry and complications reported using the revised Martin criteria. Regular audits will take place to evaluate compliance as well as the educational role of live surgery. This policy represents the consensus view of an expert panel established to advise the EAU. The EAU recognises the educational role of live surgery and endorses live case demonstration at urologic meetings that are conducted within a clearly defined regulatory framework. The overriding principle is that patient safety must take priority over all other considerations in the conduct of live surgery. Controversy exists regarding the true educational value of live surgical demonstrations on patients at surgical meetings. An EAU committee of experts developed a policy on how best to conduct live surgery at urologic meetings. The key principle is to ensure safety for every patient, including a code of conduct and checklist for live surgery, specific rules for how the surgery is organised and performed, and how each patient's results are reported to the EAU.

Objective To compare the operative outcomes, postoperative pain, and subsequent convalescence after laparoendoscopic single-site surgery (LESS) or conventional laparoscopic surgery for adnexal preservation. Study design From December 2009 to September 2010, 63 patients underwent LESS (n = 33) or a conventional laparoscopic surgery (n = 30) for cyst enucleation. The overall operative outcomes including postoperative pain measurement using the visual analog scale (VAS) were evaluated (time points 6, 24, and 24 hours). The convalescence data included data obtained from questionnaires on the need for analgesics and on patient-reported time to recovery end points. Results The preoperative characteristics did not significantly differ between the two groups. The postoperative hemoglobin drop was higher in the LESS group than in the conventional laparoscopic surgery group (P = 0.048). Postoperative pain at each VAS time point, oral analgesic requirement, intramuscular analgesic requirement, and the number of days until return to work were similar in both groups. Conclusion In adnexa-preserving surgery performed in reproductive-age women, the operative outcomes, including satisfaction of the patients and convalescence after surgery, are comparable for LESS and conventional laparoscopy. LESS may be a feasible and a promising alternative method for scarless abdominal surgery in the treatment of young women with adnexal cysts PMID:22448110

Deep Vein Thrombosis After Complex Posterior Spine Surgery: Does Staged Surgery Make a Difference?

PubMed

Edwards, Charles C; Lessing, Noah L; Ford, Lisa; Edwards, Charles C

Retrospective review of a prospectively collected database. To assess the incidence of deep vein thrombosis (DVT) associated with single- versus multistage posterior-only complex spinal surgeries. Dividing the physiologic burden of spinal deformity surgery into multiple stages has been suggested as a potential means of reducing perioperative complications. DVT is a worrisome complication owing to its potential to lead to pulmonary embolism. Whether or not staging affects DVT incidence in this population is unknown. Consecutive patients undergoing either single- or multistage posterior complex spinal surgeries over a 12-year period at a single institution were eligible. All patients received lower extremity venous duplex ultrasonographic (US) examinations 2 to 4 days postoperatively in the single-stage group and 2 to 4 days postoperatively after each stage in the multistage group. Multivariate logistic regression was used to assess the independent contribution of staging to developing a DVT. A total of 107 consecutive patients were enrolled-26 underwent multistage surgery and 81 underwent single-stage surgery. The single-stage group was older (63 years vs. 45 years; p < .01) and had a higher Charlson comorbidity index (2.25 ± 1.27 vs. 1.23 ± 1.58; p < .01). More multistage patients had positive US tests than single-stage patients (5 of 26 vs. 6 of 81; 19% vs. 7%; p = .13). Adjusting for all the above-mentioned covariates, a multistage surgery was 8.17 (95% CI 0.35-250.6) times more likely to yield a DVT than a single-stage surgery. Patients who undergo multistage posterior complex spine surgery are at a high risk for developing a DVT compared to those who undergo single-stage procedures. The difference in DVT incidence may be understated as the multistage group had a lower pre- and intraoperative risk profile with a younger age, lower medical comorbidities, and less per-stage blood loss.

Damage control surgery (DCS) is an important option in the store of war surgery and surgery of trauma. The main purpose of our investigation was to specify the percentage of the injured who need DCS. We performed retrospective study of the patients in the combat operations in Chechnya (1994-2002) and in peacetime (2005-2010). Total lethality in group with the standard surgical approach was 62.3%. It was significantly higher than the lethality in group of patients who underwent DCS - 50.0% (p < 0.05). Thus, the experience of DCS in War Surgery Department confirms that DCS is perspective tendency in treatment of patients with severe and extremely severe trauma, and allows decreasing lethality in 12.3%.

Sustaining a career in surgery.

Surgery is a demanding career with great rewards and equally great challenges. In order to sustain our careers as well as the careers of our colleagues, it is important to understand and address the physical, psychological and spiritual challenges of surgery. With rare exception, the majority of surgery residents and practicing surgeons who prematurely leave surgery do so because they find the work to be physically, emotionally or spiritually incompatible with the vision they have for their life. Understanding these issues and providing solutions to improve surgeon wellness can help prevent societal loss of these highly trained professionals and suffering for surgeons and their families.

From classical surgery to Robotic Assisted Surgery, there is a long way allowed by Minimal Invasive Surgery' improvements. The last three decades have witnessed a prodigious development of minimally invasive surgery (MIS) and especially in the field of laparoscopic pediatric surgery but there are several limitations in the use of conventional laparoscopic surgery and Robotic Assisted Surgery was developed to relieve these drawbacks. This new technology enables today the performance of a wide variety of procedures in children with a minimally invasive approach. As for all new technologies, an objective evaluation is essential with the need to respond to several questions: Is the technology feasible? Is the technology safe? Is the technology efficient? Does it bring about benefits compared with current technology? What are the procedures derived from most benefits of robotic assistance? How to assume the transition from open surgery to Minimal Invasive access for RAS? In the first part of this article, the authors give details about technical concerns and then describe the implementation process with its organization, pitfalls, successes, and issues from human resources and financial standpoints. The learning curve is then described and a special focus on small children weighing less than 15 Kg is developed. Finally, the concept of evaluation of this emerging technology is evocated and financial concerns are developed.

To evaluate how patient satisfaction after cataract surgery is associated with postoperative visual acuity, visual functioning, dry eye signs and symptoms, health anxiety, and depressive symptoms. Fifty-four patients (mean age: 68.02 years) were assessed 2 months after uneventful phacoemulsification; 27 were unsatisfied with their postoperative results and 27 were satisfied. They completed the following questionnaires: Visual Function Index-14 (VF-14), Ocular Surface Disease Index (OSDI), Shortened Health Anxiety Inventory (SHAI), and Shortened Beck Depression Inventory. Testing included logarithm of the Minimum Angle of Resolution (logMAR) uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), dry eye tests (tear meniscus height and depth measured by spectral optical coherence tomography, tear film break-up time (TBUT), ocular surface staining, Schirmer 1 test, and meibomian gland dysfunction grading). Postoperative UCVA, BCVA, and the dry eye parameters - except TBUT - showed no statistically significant difference between the two groups (p > 0.130). However, the VF-14 scores, the OSDI scores, and the SHAI scores were significantly worse in the unsatisfied patient group (p < 0.002). No significant correlations were found between visual acuity measures and visual functioning (r < 0.170, p > 0.05). However, the VF-14 scores correlated with the OSDI scores (r = -0.436, p < 0.01) and the OSDI scores correlated with the SHAI scores (r = 0.333, p < 0.05). Multiple logistic regression revealed an adjusted association between patient satisfaction and dry eye symptoms (odds ratio = 1.46, 95% CI = 1.02-2.09, p = 0.038) and visual functioning (odds ratio = 0.78, 95% CI = 0.60-1.0, p = 0.048). Our results suggest that patient-reported visual functioning, dry eye symptoms, and health anxiety are more closely associated with patients' postoperative satisfaction than with the objective clinical measures of visual acuity or the signs of dry eye.

Fast-track surgery is a multidisciplinary approach to surgery that results in faster recovery from surgery and decreased length of stay (LOS). The aims of this study were as follows: (i) to report on the processes required for the introduction of fast-track surgery to a gynaecological oncology unit and (ii) to report the results of a clinical audit conducted after the protocol's implementation. A fast-track protocol, specific to our unit, was developed after a series of multidisciplinary meetings. The protocol, agreed upon by those involved in the care of women in our unit, was then introduced into clinical practice. An audit was conducted of all women undergoing laparotomy, with known or suspected malignancy. Information on LOS, complication and readmission rates was collected. Descriptive statistics and Poisson regression were used for statistical analysis. The developed protocol involved a multidisciplinary approach to pre-, intra- and postoperative care. The audit included 104 consecutive women over a 6-month period, who were followed for 6 weeks postoperatively. The median LOS was 4 days. The readmission rate was 7% and the complication rate was 19% (1% intraoperative, 4% major and 14% minor). Multivariate analysis revealed that increased duration of surgery and increasing age were predictors of longer LOS. The development of a fast-track protocol is achievable in a gynaecological oncology unit, with input from a multidisciplinary team. Effective implementation of the protocol can result in a short LOS, with acceptable complication and readmission rates when applied non-selectively to gynaecological oncology patients. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Minimally invasive glaucoma surgery as primary stand-alone surgery for glaucoma.

PubMed

Kerr, Nathan M; Wang, Jing; Barton, Keith

2017-05-01

Recently, many new devices and procedures have been developed to lower intraocular pressure in a less invasive and purportedly safer manner than traditional glaucoma surgery. These new devices might encourage an earlier transition to surgery and reduce the long-term commitment to topical glaucoma medications with their associated compliance and intolerance issues. Although often seen as an adjunct to cataract surgery, a growing body of evidence suggests that primary minimally invasive glaucoma surgery may be a viable initial treatment option. New studies have shown that primary ab interno trabeculectomy (Trabectome, NeoMedix Inc., Tustin, CA, USA), trabecular micro-bypass stent insertion (iStent and iStent Inject, Glaukos Corporation, Laguna Hills, CA, USA), canalicular scaffolding (Hydrus, Invantis Inc., Irvine CA, USA), the ab interno gel Implant (XEN, Allergan, Dublin, Ireland) or supraciliary stenting (CyPass Micro-Stent, Alcon, Fort Worth, TX, USA) may lower the lowering intraocular pressure and/or topical medication burden in phakic or pseudophakic patients with glaucoma. This effect seems to last at least 12 months but reliable cost-effectiveness and quality of life indicators have not yet been established by investigator-initiated randomized trials of sufficient size and duration. © 2016 Royal Australian and New Zealand College of Ophthalmologists.

Integrated (0 + 5) vascular surgery (VS) residency programs must include 24 months of training in core general surgery. The Accreditation Council for Graduate Medical Education currently does not require specific case numbers in general surgery for 0 + 5 trainees; however, program directors have structured this time to optimize operative experience. The aim of this study is to determine the case volume and type of cases that VS residents are exposed to during their core surgery training. Accreditation council for graduate medical education operative logs for current 0 + 5 VS residents were obtained and retrospectively reviewed to determine general surgery case volume and distribution between open and laparoscopic cases performed. Standard statistical methods were applied. A total of 12 integrated VS residency programs provided operative case logs for current residents. A total of 41 integrated VS residents in clinical years 2 through 5. During the postgraduate year-1 training year, residents participated in significantly more open than laparoscopic general surgery cases (p < 0.0001). This difference was consistent over the first 3 years of training. The most frequently logged open general surgery cases are hernia repair (20%), skin and soft tissue (7.4%), and breast (6.3%). Residents in programs with core surgery over 3 years participated in significantly more general surgery operations compared with residents in programs with core surgery spread out over 4 years (p = 0.035). 0 + 5 VS residents perform significantly more open operations than laparoscopic operations during their core surgery training. The majority of these operations are minor, nonabdominal procedures. The 0 + 5 VS residency program general surgery operative training requirements should be reevaluated and case minimums defined. The general surgery training component of 0 + 5 VS residencies may need to be restructured to meet the needs of current and future trainees. Copyright © 2016 Association of

There is currently significant demand for minimally invasive thyroid surgery; however the majority of proposed surgical approaches necessitate a compromise between minimal tissue dissection with a visible cervical scar or extensive tissue dissection with a remote, hidden scar. The development of transoral endoscopic thyroid surgery however provides an approach which is truly minimally invasive, as it conceals the incision within the oral cavity without significantly increasing the amount of required dissection. The transoral endoscopic approach however presents multiple technical challenges, which could be overcome with the incorporation of a robotic operating system. This manuscript summarizes the literature on the feasibility and current clinical experience with transoral robotic thyroid surgery. PMID:26425456

As the prevalence of obesity increases, so, too, do the prevalences of weight-related diseases and surgical procedures to promote weight loss. It is important for neuro-ophthalmologists to be familiar with these procedures and possible downstream effects on afferent and efferent visual function. Review of ophthalmology, neurology, general surgery, obesity, endocrinology, nutrition, psychiatry, and neurosurgery literature. Bariatric surgery is a safe and effective treatment for weight loss in obese individuals. There is Level IV evidence that it is associated with improvement in idiopathic intracranial hypertension (IIH). Laboratory nutrient deficiencies are common following some types of bariatric procedures. Symptomatic deficiencies are less common but can be devastating. Thiamine deficiency can cause nystagmus and other symptoms in weeks to months after surgery, whereas B12 or copper deficiency can cause optic neuropathy in years to decades following bariatric surgery. Bariatric surgery is a potential treatment for IIH. Postoperative vitamin deficiencies may cause nystagmus, optic neuropathy, nyctalopia, and/or ophthalmoparesis weeks to years after surgery.

Time-to-surgery from cancer diagnosis has increased in the United States. We aimed to determine the association between time-to-surgery and oncologic outcomes in patients with resectable pancreatic ductal adenocarcinoma undergoing upfront surgery. The 2004-2012 National Cancer Database was reviewed for patients undergoing curative-intent surgery without neoadjuvant therapy for clinical stage I-II pancreatic ductal adenocarcinoma. A multivariable Cox model with restricted cubic splines was used to define time-to-surgery as short (1-14 days), medium (15-42), and long (43-120). Overall survival was examined using Cox shared frailty models. Secondary outcomes were examined using mixed-effects logistic regression models. Of 16,763 patients, time-to-surgery was short in 34.4%, medium in 51.6%, and long in 14.0%. More short time-to-surgery patients were young, privately insured, healthy, and treated at low-volume hospitals. Adjusted hazards of mortality were lower for medium (hazard ratio 0.94, 95% confidence interval, .90, 0.97) and long time-to-surgery (hazard ratio 0.91, 95% confidence interval, 0.86, 0.96) than short. There were no differences in adjusted odds of node positivity, clinical to pathologic upstaging, being unresectable or stage IV at exploration, and positive margins. Medium time-to-surgery patients had higher adjusted odds (odds ratio 1.11, 95% confidence interval, 1.03, 1.20) of receiving an adequate lymphadenectomy than short. Ninety-day mortality was lower in medium (odds ratio 0.75, 95% confidence interval, 0.65, 0.85) and long time-to-surgery (odds ratio 0.72, 95% confidence interval, 0.60, 0.88) than short. In this observational analysis, short time-to-surgery was associated with slightly shorter OS and higher perioperative mortality. These results may suggest that delays for medical optimization and referral to high volume surgeons are safe. Published by Elsevier Inc.

Although there is no agreement on a definition of elderly, commonly an age cutoff of ≥65 or 75 years is used. Nowadays most of malignancies requiring surgical treatment are diagnosed in old population. Comorbidities and frailty represent well-known problems during and after surgery in elderly patients. Minimally invasive surgery offers earlier postoperative mobilization, less blood loss, lower morbidity as well as reduction in hospital stay and as such represents an interesting and validated option for elderly population. Robot-assisted surgery is a recent improvement of conventional minimally invasive surgery. We provided a complete review of old and very old patients undergoing robot-assisted surgery for oncologic and general surgery interventions. A retrospective review of all patients undergoing robot-assisted surgery in our General Surgery Unit from September 2012 to June 2016 was conducted. Analysis was performed for the entire cohort and in particular for three of the most performed surgeries (gastric resections, right colectomy, and liver resections) classifying patients into three age groups: ≤64, 65-79, and ≥80. Data from these three different age groups were compared and examined in respect of different outcomes: ASA score, comorbidities, oncologic outcomes, conversion rate, estimated blood loss, hospital stay, geriatric events, mortality, etc. Using our in-patient robotic surgery database, we retrospectively examined 363 patients, who underwent robot-assisted surgery for different diseases (402 different robotic procedures): colorectal surgery, upper GI, HPB, etc.; the oncologic procedures were 81%. Male were 56%. The mean age was 65.63 years (18-89). Patients aged ≥65 years represented 61% and ≥80 years 13%. Overall conversion rate was of 6%, most in the group 65-79 years (59% of all conversions). The more frequent diseases treated were colorectal surgery 43%, followed by hepatobilopancreatic surgery 23.4%, upper gastro-intestinal 23

Fibrous hyperplasia is treated by surgical incision using a scalpel, together with removal of the source of chronic trauma. However, scalpel techniques do not provide the haemostasis that is necessary when dealing with highly vascular tissues. Diode laser surgery can be used in the management of oral tissues due to its high absorption by water and haemoglobin, and has provided good results in both periodontal surgery and oral lesions. The aim of the present study was to compare the effects of diode laser surgery to those of the conventional technique in patients with fibrous hyperplasia. A randomized clinical trial was performed in which surgical and postoperative evaluations were analyzed. On comparison of the laser-treated (study group) patients to those treated with a scalpel (control group), significant differences were observed in the duration of surgery and the use of analgesic medications. Over a 3-week period, clinical healing of the postoperative wound was significantly faster in the control group as compared to the study group. In conclusion, diode laser surgery proved to be more effective and less invasive when compared to scalpel surgery in the management of fibrous hyperplasia. However, wound healing proved to be faster when using scalpel surgery. Copyright © 2015 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

BACKGROUND: Canada’s contributions toward the 21st century’s practice of thoracic surgery have been both unique and multilayered. Scattered throughout are tales of pioneers where none had gone before, where opportunities were greeted by creativity and where iconic figures followed one another. OBJECTIVE: To describe the numerous and important achievements of Canadian thoracic surgeons in the areas of surgery for pulmonary tuberculosis, thoracic oncology, airway surgery and lung transplantation. METHOD: Information was collected through reading of the numerous publications written by Canadian thoracic surgeons over the past 100 years, interviews with interested people from all thoracic surgery divisions across Canada and review of pertinent material form the archives of several Canadian hospitals and universities. RESULTS: Many of the developments occurred by chance. It was the early and specific focus on thoracic surgery, to the exclusion of cardiac and general surgery, that distinguishes the Canadian experience, a model that is now emerging everywhere. From lung transplantation in chimera twin calves to ex vivo organ preservation, from the removal of airways to tissue regeneration, and from intensive care research to complex science, Canadians have excelled in their commitment to research. Over the years, the influence of Canadian thoracic surgery on international practice has been significant. CONCLUSIONS: Canada spearheaded the development of thoracic surgery over the past 100 years to a greater degree than any other country. From research to education, from national infrastructures to the regionalization of local practices, it happened in Canada.

Robotic systems in spine surgery.

Surgical robotic systems have been available for almost twenty years. The first surgical robotic systems were designed as supportive systems for laparoscopic approaches in general surgery (the first procedure was a cholecystectomy in 1987). The da Vinci Robotic System is the most common system used for robotic surgery today. This system is widely used in urology, gynecology and other surgical disciplines, and recently there have been initial reports of its use in spine surgery, for transoral access and anterior approaches for lumbar inter-body fusion interventions. SpineAssist, which is widely used in spine surgery, and Renaissance Robotic Systems, which are considered the next generation of robotic systems, are now FDA approved. These robotic systems are designed for use as guidance systems in spine instrumentation, cement augmentations and biopsies. The aim is to increase surgical accuracy while reducing the intra-operative exposure to harmful radiation to the patient and operating team personnel during the intervention. We offer a review of the published literature related to the use of robotic systems in spine surgery and provide information on using robotic systems.

Robot-assisted surgery: the future is here.

Gerhardus, Diana

According to L. Wiley Nifong, director of robotic surgery at East Carolina University's Brody School of Medicine, "Nationally, only one-fourth of the 15 million surgeries performed each year are done with small incisions or what doctors call 'minimally invasive surgery'." Robots could raise that number substantially (Stark 2002). Currently, healthcare organizations use robot technology for thoracic, abdominal, pelvic, and neurological surgical procedures. Minimally invasive surgery reduces the amount of inpatient hospital days, and the computer in the system filters any hand tremors a physician may have during the surgery. The use of robot-assisted surgery improves quality of care because the patient experiences less pain after the surgery. Robot-assisted surgery demonstrates definite advantages for the patient, physician, and hospital; however, healthcare organizations in the United States have yet to acquire the technology because of implementation costs and the lack of FDA (Food and Drug Administration) approval for using the technology for certain types of heart procedures. This article focuses on robot-assisted surgery advantages to patients, physicians, and hospitals as well as on the disadvantages to physicians. In addition, the article addresses implementation costs, which creates financial hurdles for most healthcare organizations; offers recommendations for administrators to embrace this technology for strategic positioning; and enumerates possible roles for robots in medicine.

Advantages of robotics in benign gynecologic surgery.

Truong, Mireille; Kim, Jin Hee; Scheib, Stacey; Patzkowsky, Kristin

2016-08-01

The purpose of this article is to review the literature and discuss the advantages of robotics in benign gynecologic surgery. Minimally invasive surgery has become the preferred route over abdominal surgery. The laparoscopic or robotic approach is recommended when vaginal surgery is not feasible. Thus far, robotic gynecologic surgery data have demonstrated feasibility, safety, and equivalent clinical outcomes in comparison with laparoscopy and better clinical outcomes compared with laparotomy. Robotics was developed to overcome challenges of laparoscopy and has led to technological advantages such as improved ergonomics, visualization with three-dimensional capabilities, dexterity and range of motion with instrument articulation, and tremor filtration. To date, applications of robotics in benign gynecology include hysterectomy, myomectomy, endometriosis surgery, sacrocolpopexy, adnexal surgery, tubal reanastomosis, and cerclage. Though further data are needed, robotics may provide additional benefits over other approaches in the obese patient population and in higher complexity cases. Challenges that arose in the earlier adoption stage such as the steep learning curve, costs, and operative times are becoming more optimized with greater experience, with implementation of robotics in high-volume centers and with improved training of surgeons and robotic teams. Robotic laparoendoscopic single-site surgery, albeit still in its infancy where technical advantages compared with laparoscopic single-site surgery are still unclear, may provide a cost-reducing option compared with multiport robotics. The cost may even approach that of laparoscopy while still conferring similar perioperative outcomes. Advances in robotic technology such as the single-site platform and telesurgery, have the potential to revolutionize the field of minimally invasive gynecologic surgery. Higher quality evidence is needed to determine the advantages and disadvantages of robotic surgery in benign

Minimally invasive surgical techniques are becoming increasingly common in gynecologic surgery. However, traditional laparoscopy can be challenging. A robotic surgical system gives several advantages over traditional laparoscopy and has been incorporated into reproductive gynecological surgeries. The objective of this article is to review recent publications on robotically-assisted laparoscopy for reproductive surgery. Recent clinical research supports robotic surgery as resulting in less post-operative pain, shorter hospital stays, faster return to normal activities, and decreased blood loss. Reproductive outcomes appear similar to alternative approaches. Drawbacks of robotic surgery include longer operating room times, the need for specialized training, and increased cost. Larger prospective studies comparing robotic approaches with laparoscopy and conventional open surgery have been initiated and information regarding long-term outcomes after robotic surgery will be important in determining the ultimate utility of these procedures.

Plastic surgery after weight loss: current concepts in massive weight loss surgery.

PubMed

Gusenoff, Jeffrey A; Rubin, J Peter

2008-01-01

The authors begin their discussion of current concepts in massive weight loss (MWL) surgery by offering terminological guidelines that help define reconstructive and aesthetic concepts and procedures for the post-MWL patient. Measures for effective preoperative nutritional and metabolic screening include assessment of weight fluctuations over time, constitutional symptoms, and medications and nutritional supplements. Although there is no established body-mass index (BMI) threshold above which surgery should be refused, higher BMIs have been associated with increased complications. Residual medical problems and psychosocial issues require assessment before surgery, with appropriate specialist consultation as necessary. Consultation with patients concerning the different expectations for functional versus aesthetic procedures and issues such as postoperative scarring and the common incidence of wound healing problems is essential. Patient safety is paramount in decisions to combine multiple procedures and plan stages. The authors often recommend combining abdominoplasty and mastopexy. Surgeon experience, operative setting, and a patient's medical status are factors which influence how much surgery should be performed in the same operative setting. Centers of Excellence in body contouring that provide a team approach combining comprehensive patient evaluation, outcomes research, and surgical training may be the optimal approach for treating the massive weight loss patient.

The benefit of computer-assisted planning in orthognathic surgery (OGS) has been extensively documented over the last decade. This study aimed to evaluate the accuracy of three-dimensional (3D) virtual planning in surgery-first OGS. Fifteen patients with skeletal class III malocclusion who underwent bimaxillary OGS with surgery-first approach were included. A composite skull model was reconstructed using data from cone-beam computed tomography and stereolithography from a scanned dental cast. Surgical procedures were simulated using Simplant O&O software, and the virtual plan was transferred to the operation room using 3D-printed splints. Differences of the 3D measurements between the virtual plan and postoperative results were evaluated, and the accuracy was reported using root mean square deviation (RMSD) and the Bland-Altman method. The virtual planning was successfully transferred to surgery. The overall mean linear difference was 0.88 mm (0.79 mm for the maxilla and 1 mm for the mandible), and the overall mean angular difference was 1.16°. The RMSD ranged from 0.86 to 1.46 mm and 1.27° to 1.45°, within the acceptable clinical criteria. In this study, virtual surgical planning and 3D-printed surgical splints facilitated the diagnosis and treatment planning, and offered an accurate outcome in surgery-first OGS.

30 Years of Robotic Surgery.

The idea of reproducing himself with the use of a mechanical robot structure has been in man's imagination in the last 3000 years. However, the use of robots in medicine has only 30 years of history. The application of robots in surgery originates from the need of modern man to achieve two goals: the telepresence and the performance of repetitive and accurate tasks. The first "robot surgeon" used on a human patient was the PUMA 200 in 1985. In the 1990s, scientists developed the concept of "master-slave" robot, which consisted of a robot with remote manipulators controlled by a surgeon at a surgical workstation. Despite the lack of force and tactile feedback, technical advantages of robotic surgery, such as 3D vision, stable and magnified image, EndoWrist instruments, physiologic tremor filtering, and motion scaling, have been considered fundamental to overcome many of the limitations of the laparoscopic surgery. Since the approval of the da Vinci(®) robot by international agencies, American, European, and Asian surgeons have proved its factibility and safety for the performance of many different robot-assisted surgeries. Comparative studies of robotic and laparoscopic surgical procedures in general surgery have shown similar results with regard to perioperative, oncological, and functional outcomes. However, higher costs and lack of haptic feedback represent the major limitations of current robotic technology to become the standard technique of minimally invasive surgery worldwide. Therefore, the future of robotic surgery involves cost reduction, development of new platforms and technologies, creation and validation of curriculum and virtual simulators, and conduction of randomized clinical trials to determine the best applications of robotics.

The objective of our study was to characterize providers' impressions of factors contributing to disproportionate rates of morbidity and mortality in emergency general surgery to identify targets for care quality improvement. Emergency general surgery is characterized by a high-cost burden and disproportionate morbidity and mortality. Factors contributing to these observed disparities are not comprehensively understood and targets for quality improvement have not been formally developed. Using a grounded theory approach, emergency general surgery providers were recruited through purposive-criterion-based sampling to participate in semi-structured interviews and focus groups. Participants were asked to identify contributors to emergency general surgery outcomes, to define effective care for EGS patients, and to describe operating room team structure. Interviews were performed to thematic saturation. Transcripts were iteratively coded and analyzed within and across cases to identify emergent themes. Member checking was performed to establish credibility of the findings. A total of 40 participants from 5 academic hospitals participated in either individual interviews (n = 25 [9 anesthesia, 12 surgery, 4 nursing]) or focus groups (n = 2 [15 nursing]). Emergency general surgery was characterized by an exceptionally high level of variability, which can be subcategorized as patient-variability (acute physiology and comorbidities) and system-variability (operating room resources and workforce). Multidisciplinary communication is identified as a modifier to variability in emergency general surgery; however, nursing is often left out of early communication exchanges. Critical variability in emergency general surgery may impact outcomes. Patient-variability and system-variability, with focus on multidisciplinary communication, represent potential domains for quality improvement in this field. Copyright © 2017 Elsevier Inc.

Magnification of the surgical field using the operating microscope facilitated profound innovations in retinal surgery in the 1970s, such as pars plana vitrectomy. Although surgical instrumentation and illumination techniques are continually developing, the operating microscope for vitreoretinal procedures has remained essentially unchanged and currently limits the surgeon's depth perception and assessment of subtle microanatomy. Optical coherence tomography (OCT) has revolutionized clinical management of retinal pathology, and its introduction into the operating suite may have a similar impact on surgical visualization and treatment. In this article, we review the evolution of OCT for retinal surgery, from perioperative analysis to live volumetric (four-dimensional, 4D) image-guided surgery. We begin by briefly addressing the benefits and limitations of the operating microscope, the progression of OCT technology, and OCT applications in clinical/perioperative retinal imaging. Next, we review intraoperative OCT (iOCT) applications using handheld probes during surgical pauses, two-dimensional (2D) microscope-integrated OCT (MIOCT) of live surgery, and volumetric MIOCT of live surgery. The iOCT discussion focuses on technological advancements, applications during human retinal surgery, translational difficulties and limitations, and future directions.

To evaluate the results of combined multilevel surgery with transoral robotic surgery (TORS) in patients with obstructive sleep apnea/hypopnea syndrome for multilevel upper airway obstruction. Subjects who underwent combined sleep surgery via TORS were evaluated. The drug-induced sleep endoscopy was used in diagnosing the presence of level-specific upper airway collapse and to detect the type of surgery. Pre- and postoperative Apnea-hypopnea index, Epworth sleepiness scale lowest oxygen saturation, total operation time, robotic set-up time and robotic surgery time, blood loss value, and complications were recorded. Twenty five subjects were identified. All subjects underwent base of tongue (BOT) + epiglottoplasty. The tracheotomy was not performed for any patient. Overall, 72% of patients met the criteria for cure, 8% met the criteria for cure, and 20% of patients met the criteria for failure. There was a significant decrease between preoperative and postoperative Apnea-hypopnea index scores (28.7 ± 17.8 SD versus 9.4 ± 12.4, P = 0.000) and Epworth sleepiness scale scores (13.5 ± 2.8 versus 3.4 ± 1.6, P = 0.000). There was a significant increase between preoperative and postoperative ED SPO2 levels (80.7 ± 7.6 versus 82.6 ± 18.1, P = 0.001). TORS BOT, epiglottoplasty, and multilevel procedures in patients with obstructive sleep apnea/hypopnea syndrome can be regarded as feasible, safe, and effective technique.

Enhanced Recovery After Surgery: A Review.

PubMed

Ljungqvist, Olle; Scott, Michael; Fearon, Kenneth C

2017-03-01

Enhanced Recovery After Surgery (ERAS) is a paradigm shift in perioperative care, resulting in substantial improvements in clinical outcomes and cost savings. Enhanced Recovery After Surgery is a multimodal, multidisciplinary approach to the care of the surgical patient. Enhanced Recovery After Surgery process implementation involves a team consisting of surgeons, anesthetists, an ERAS coordinator (often a nurse or a physician assistant), and staff from units that care for the surgical patient. The care protocol is based on published evidence. The ERAS Society, an international nonprofit professional society that promotes, develops, and implements ERAS programs, publishes updated guidelines for many operations, such as evidence-based modern care changes from overnight fasting to carbohydrate drinks 2 hours before surgery, minimally invasive approaches instead of large incisions, management of fluids to seek balance rather than large volumes of intravenous fluids, avoidance of or early removal of drains and tubes, early mobilization, and serving of drinks and food the day of the operation. Enhanced Recovery After Surgery protocols have resulted in shorter length of hospital stay by 30% to 50% and similar reductions in complications, while readmissions and costs are reduced. The elements of the protocol reduce the stress of the operation to retain anabolic homeostasis. The ERAS Society conducts structured implementation programs that are currently in use in more than 20 countries. Local ERAS teams from hospitals are trained to implement ERAS processes. Audit of process compliance and patient outcomes are important features. Enhanced Recovery After Surgery started mainly with colorectal surgery but has been shown to improve outcomes in almost all major surgical specialties. Enhanced Recovery After Surgery is an evidence-based care improvement process for surgical patients. Implementation of ERAS programs results in major improvements in clinical outcomes and cost

Value of Pediatric Orthopaedic Surgery.

Value has become the buzzword of contemporaneous health care reform. Value is defined as outcomes relative to costs. Orthopaedic surgery has come under increasing scrutiny due to high procedural costs. However, orthopaedic surgery may actually be a great value given the benefits of treatment. The American Academy of Orthopaedic Surgeons (AAOS) Value Project team was tasked to develop a model for assessing the benefits of orthopaedic surgery including indirect costs related to productivity and health-related quality of life. This model was applied to 5 orthopaedic conditions demonstrating robust societal and economic value. In all cost-effectiveness models, younger patients demonstrated greater cost-effectiveness given increased lifespan and productivity. This has tremendous implications within the field of pediatric orthopedic surgery. Pediatric orthopaedics may be the best value in medicine!

Cosmetic surgery and conscientious objection.

2017-04-01

In this paper, I analyse the issue of conscientious objection in relation to cosmetic surgery. I consider cases of doctors who might refuse to perform a cosmetic treatment because: (1) the treatment aims at achieving a goal which is not in the traditional scope of cosmetic surgery; (2) the motivation of the patient to undergo the surgery is considered trivial; (3) the patient wants to use the surgery to promote moral or political values that conflict with the doctor's ones; (4) the patient requires an intervention that would benefit himself/herself, but could damage society at large.

Quality of Life After Bariatric Surgery.

Mazer, Laura M; Azagury, Dan E; Morton, John M

2017-06-01

The purpose of this review is to provide an introduction to quality of life (QOL) outcomes after bariatric surgery and a summary of the current evidence. QOL has been emphasized in bariatric surgery since the NIH Consensus Conference statement in 1991. Initial studies were limited to 1- and 2-year follow-up. More recent findings have expanded the follow-up period up to 12 years, providing a better description of the impact on long-term QOL. Overall, there is little to no consensus regarding the definition of QOL or the ideal survey. Bariatric surgery has the greatest impact on physical QOL, and the impact on mental health remains unclear. There are some specific and less frequently reported threats to quality of life after bariatric surgery that are also discussed. Obesity has a definite impact on quality of life, even without other comorbidities, and surgery for obesity results in significant and lasting improvements in patient-reported quality of life outcomes. This conclusion is limited by a wide variety of survey instruments and absence of consensus on the definition of QOL after bariatric surgery.

Background As the prevalence of obesity increases, so are the prevalences of weight related diseases and the incidence of surgical procedures to promote weight loss. It is important for neuro-ophthalmologists to be familiar with these procedures and possible downstream effects on afferent and efferent visual function. Evidence acquisition Review of ophthalmology, neurology, general surgery, obesity, endocrinology, nutrition, psychiatry and neurosurgery literature. Results Bariatric surgery is a safe and effective treatment for weight loss in obese individuals. There is level IV evidence that it is associated with improvement in idiopathic intracranial hypertension(IIH). Laboratory nutrient deficiencies are common following some types of bariatric procedures. Symptomatic deficiencies are less common but can be devastating. Thiamine deficiency can cause nystagmus and other symptoms in weeks to months following surgery, B12 or copper deficiency can cause optic neuropathy in the years to decades following bariatric surgery. Conclusions Bariatric surgery may be a treatment for IIH. Postoperative vitamin deficiencies may present with nystagmus, optic neuropathy, nyctalopia and/or ophthalmoparesis weeks to years after surgery. PMID:26764529

The medical institutions in the country have advanced together with the development of the state of Israel. Plastic surgery, which has progressed significantly during the 20th century, has also grown rapidly in the new state. The arrival of Jewish plastic surgeons from all over the world with the knowledge and experience gained in their countries of origin, as well as the need for reconstructive surgical treatment for many combat injured soldiers, also contributed to the development of plastic surgery. This review tells the story of plastic surgery in Israel, since its foundation until nowadays. This article reviews the work of the founders of plastic surgery in Israel, indicating significant milestones in its development, and clinical and scientific contribution to the international plastic surgery profession. Moreover, the article describes the current condition of the field of plastic surgery in Israel and presents the trends and the future challenges facing the next generation of plastic surgery in Israel.

Sepsis in general surgery: a deadly complication.

Sepsis is a deadly and potentially preventable complication. A better understanding of sepsis in general surgery patients is needed to help direct resources to those patients at highest risk for death from sepsis. We identified risk factors for sepsis in general surgery patients by using the National Surgical Quality Improvement Project database. Analysis of the database identified 3 major risk factors for both the development of sepsis and death from sepsis in general surgery patients. These risk factors are age older than 60 years, need for emergency surgery, and the presence of comorbid conditions. Risk factors for death from sepsis or septic shock in general surgery patients include age older than 60 years, need for emergency surgery, and the presence of preexisting comorbidities. These findings emphasize the need for early recognition through aggressive sepsis screening and rapid implementation of evidence-based interventions for sepsis and septic shock in general surgery patients with these risk factors.

Necessity of suction drains in gynecomastia surgery.

The aim of gynecomastia surgery is to restore a normal chest contour with minimal signs of breast surgery. The authors examine the rate of complications in gynecomastia surgery when no closed-suction drains are placed. One hundred thirty-eight consecutive male patients who underwent gynecomastia surgery without drains were retrospectively analyzed to determine whether the absence of drains adversely affected patient outcomes. Patients were managed by ultrasonic-assisted liposuction both with and without the pull-through technique. The mean age of the patients was 29 years, and the mean volume of breast tissue aspirated was 350 mL per beast. Pull-through was needed in 23 cases. There was only 1 postoperative hematoma. These results are comparable with previously published data for gynecomastia surgery in which drains were placed, suggesting that the absence of drains does not adversely affect postoperative recovery. Routine closed-suction drainage after gynecomastia surgery is unnecessary, and it may be appropriate to omit drains after gynecomastia surgery.
