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.

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.

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 preoperative levels with the healing of the incision, and the reduction of swelling of the tissue near the incision.

Glaucoma, a common disease in the elderly population, is frequently coexistent with cataract. While the combination of filtration surgery and cataract surgery is a challenging topic with limited success, minimal invasive glaucoma surgery (MIGS), such as Xen Gel Stents, seems to provide promising results. The aim of this study was to investigate the complete and qualified therapeutic success of Xen Gel Stent implantation with (XenPhaco) and without cataract surgery. One hundred and eleven open-angle glaucoma eyes underwent implantation of Xen45 Gel Stent (AqueSys, Inc.) with or without cataract operation. Complete therapeutic success was defined as target intraocular pressure (IOP) < 18 mmHg at any time point within 6 months of follow-up without local antiglaucomatous therapy or further surgical interventions. Qualified success was defined as target IOP <18 mmHg with additional 1-2 local antiglaucomatous eye drops. Failure included all cases with the necessity of at least three local antiglaucomatous eye drops or additional glaucoma surgery. Combined implantation of Xen Gel Stent with cataract surgery was performed in 30 eyes and stand-alone Xen Gel Stent implantation was performed in 81 eyes. A complete therapeutic success was achieved in 46.9% of single Xen Gel Stent implantation, whereas 53.3% was reached with combined XenPhaco. Qualified success was seen in 2.5% in the eyes of the single Xen Gel Stent implantation group and in 3.3% of the combined surgery group. Therapeutic failure rate was 49.4% in the stand-alone group vs 46.7% in the combined group. Data were not significantly different for group and subgroup analyses. Complete and qualified therapeutic success is similar for the combination of Xen Gel Stent implantation with and without cataract surgery in open-angle glaucoma patients. MIGS using Xen Gel Stent can be recommended in situations if glaucoma surgery is indicated besides coexisting cataract.

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

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.

To evaluate the effect of intracameral carbachol on foveal thickness in patients who underwent uneventful cataract surgery. This retrospective study included two groups: the study group patients (group 1, n = 47 eyes) had uneventful cataract surgery and received only carbachol 0.01 % for miosis; the control group patients (group 2, n = 49 eyes) had uneventful cataract surgery without carbachol or any intracameral medication(s). The groups were compared for foveal thickness after cataract surgery. All phacoemulsification plus intraocular lens implantation surgeries were performed under local anesthesia via temporal clear corneal tunnel incisions. Mean values and standard deviations were calculated for preoperative and postoperative visual acuity (VA) and foveal thickness (FT) at 1 and 4 weeks. Optical coherence tomography was used for the FT measurements, with the MM6 map program. The patients in the study and control groups had a mean age of 57.78 ± 9.07 and 59.72 ± 8.96, respectively (p = 0.355). All eyes had a significant improvement in VA. In the study group, the mean FT at the visits before and 1 and 4 weeks after surgery was 216.87 ± 21.06, 228.81 ± 30.52, and 222.94 ± 29.91 μm, respectively. For the control group, the mean FT, before and 1 and 4 weeks after surgery, was 222.53 ± 17.66, 231.67 ± 23.08, and 225.41 ± 22.59 μm, respectively. Intracameral carbachol 0.01 % had no effect on foveal thickness in patients who underwent uneventful cataract surgery.

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.

Steam sterilization is an essential part of infection prevention. The literature shows that sterilization of medical instruments containing channels is not trivial. Phaco hand pieces have a simple configuration: a device contains a channel with a constant radius. No literature was found indicating whether the sterilization conditions on the inner surface of a phaco hand piece are influenced by the orientation of the hand piece. To determine whether the orientation of a phaco hand piece influences the results of a sterilization process of this device. A qualitative case study, including experiments, is performed with a protocolled combination of steam sterilizer, process, phaco hand piece, orientation of the phaco hand piece, and wrapping. In this specific case, the orientation of the hand piece influenced the result of the steam sterilization process; in vertically (upright) oriented phaco hand pieces with free water drainage, sterilization conditions are reproducibly established. In the same process, in horizontally oriented or vertically oriented hand pieces without free drainage, these conditions are not established in a reproducible way. In the investigated combination of sterilizer, process, load, loading pattern and wrapping, phaco hand pieces have to be oriented vertically (upright) with free water drainage to obtain steam sterilization conditions on the inner surface. It is likely that instruments with comparable configuration and dimensions will yield comparable results. It is therefore recommended that this issue is considered during the development of medical instruments and during performance qualifications of such instruments.

2001-06-01

Recent developments in surgical procedures for restoring accommodation saw the availability of Phaco-ersatz as a feasible procedure returning near vision to the presbyopies. In Phaco-ersatz, the presbyopic crystalline lens is extracted and replaced by a flexible polymer gel in the intact lens capsule. The ability to simultaneously correct ametropia while restoring accommodation with this procedure is seen to be extremely attractive. One strategy by which this may be achieved within the Phaco-ersatz procedure is by making use of polymer gel of different refractive indices. We assessed the feasibility of simultaneously correcting ametropia while restoring accommodation using phaco-ersatz using this approach. Two model eyes (Gullstrand and Navarro) were used to evaluate this approach. Computation results using paraxial equations and ray tracing indicated that while this approach might be feasible for the hypermetrope, its usefulness for correcting myopia is limited due to significant reductions in the resultant amplitude of accommodation. A number of practical considerations may also influence the applicability of this approach.

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.

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. The median number of surgeries performed independently by 20 th century and 21 st century trained (during their training period) were: intracapsular cataract extraction (ICCE) 10, 0; extracapsular cataract extraction (ECCE) 43, 18; small incision cataract surgery (SICS) 5, 55; phacoemulsification (Phaco) 0, 1; pterygium excision 20, 15; dacryocystectomy 11, 4; dacryocystorhinostomy 11, 2; chalazion 35, 30; trabeculectomies 5, 0; strabismus correction 0, 0; vitrectomy 0, 0; keratoplasty 0, 0; eyelid surgery 6, 2; and ocular emergencies 18, 20. Teaching of many clinical skills had improved over decades. Cataract surgery training has shifted from ICCE and ECCE to SICS and Phaco, but other surgeries were still taught sparingly. There was an enormous variation across the country in residency training which needs immediate attention.

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 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.

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.

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.

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 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.

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 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.

A systematic review of phacoemulsification cataract surgery in virtual reality simulators.

2013-01-01

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.

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.

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.

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.

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.

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

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 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.

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.

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.

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.

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 also negative for growth after a 3-minute transit/storage time. These studies support the use of unwrapped, short-cycle sterilization that adheres to the IFU of these 2 popular Food and Drug Administration-cleared sterilizers for sequential same-day cataract surgeries. A full drying phase is not necessary when the instruments are kept within the covered sterilizer containment device for prompt use on a sequential case.

Delayed presentation of retained acrylic intraocular lens (IOL) fragment after uncomplicated cataract surgery.

Capitena, Cara E; Gamett, Kevin; Pantcheva, Mina B

2016-10-01

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.

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.

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 compare surgical efficiency and multiple early clinical outcome variables in eyes undergoing phacoemulsification using either transversal or torsional ultrasound systems. Assil Eye Institute, Beverly Hills, CA, USA. Prospective, randomized, clinician-masked, contralaterally controlled single-center evaluation. 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. 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. 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. Postoperative data suggested that improved phaco efficiency may translate to a better overall safety profile for the patient.

Here, we report two patients with transomental hernia who were successfully treated with laparoscopic surgery. 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.

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.

Descemet membrane detachment (DMD) is a significant complication noted during or early after cataract surgery. Review of literature revealed a few cases of delayed-onset DMD with presentation ranging from weeks to months after cataract surgery but most of them were treated with pneumatic descemetopexy and a few ended in penetrating keratoplasty. We report this case, to highlight the usefulness of corneal venting incision with air tamponade in late-onset DMD cases not responding to pneumatic descemetopexy. A retrospective case review of a 66 year old male who presented with diminution of vision in right eye 17 days after uneventful cataract surgery was done. Visual acuity in this eye was 20/200 at presentation. DMD was noted 3 days later (approximately 3 weeks post-operatively) and Anterior Segment Optical Coherence Tomography & Scheimpflug imaging were done in view of diffuse corneal edema. Pneumatic descemetopexy was attempted thrice (twice with SF6, once with air) over a week's span with limited success at re-attaching the DM. Finally, corneal venting incision with air tamponade was done resulting in egress of supra-descemet's fluid and DM appeared apposed to stroma. Bandage contact lens (BCL) was applied at the end of the procedure. DM was seen attached the next day. Corneal edema cleared completely in 1 week. Best corrected visual acuity (BCVA) at 6 weeks follow-up was 20/30. Delayed-onset DMD should be considered as a differential diagnosis in cases with late-onset corneal edema post-cataract surgery. Anterior segment Optical Coherence Tomography (AS-OCT) and Scheimpflug Imaging are useful tools in cases with dense corneal edema. Corneal venting incision with air tamponade is an option in cases where methods like pneumatic descemetopexy fail.

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.

Phaco-efficiency test and re-aspiration analysis of repulsed particle in phacoemulsification.

2013-04-01

To measure the efficiency of phacoemulsification, we have developed a new experimental model for testing phaco-efficiency and analyzed re-aspiration of repulsed particles. Using a Kitaro wetlab system, a piece of blood agar (BA) was placed in an artificial chamber and the phacoemulsifier was placed horizontally. The settings of the phacoemulsifier (Infiniti, Alcon Laboratories) were 26 cc/min for aspiration, 350 cc/min for vacuum, and 95 cm of bottle height. The time to remove BAs was measured using Ozil 100 %, Ozil 40 %, and longitudinal 40 % of phaco power. The angle between the re-aspirated BA particles and the axis of the phacoemulsifier (re-aspiration zone, degree) was analyzed. The average time (seconds) to remove BAs was lower in the Ozil 100 % and the Ozil 40 % mode than in the longitudinal mode (0.37 ± 0.39, 0.85 ± 0.57, and 2.22 ± 1.40 respectively, P value < 0.01). Repulsion exceeding 1 mm occurred more frequently in the longitudinal mode than in the Ozil 100 % mode (100 % vs 40 %, P value = 0.01, Fisher's exact test). The average of re-aspiration zone was 25.9 ± 14.5 in the longitudinal 40 % and 54.0 ± 23.0 in the Ozil 40 % (P value = 0.016). The Ozil mode was more efficient than the longitudinal mode. In addition, the Ozil mode provided less repulsion and wider aspiration zone.

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.

Since most liposuction incisions heal uneventfully, difficult healing in such incisions must be investigated. 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.

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.

Cataract surgery in a case of carotid cavernous fistula

PubMed Central

Nair, Akshay Gopinathan; Praveen, Smita Vittal; Noronha, Veena Olma

2014-01-01

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

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.

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.

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.

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

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.

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.

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.

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.

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.

Preliminary experience in transoral laryngeal surgery with a flexible robotic system for benign lesions of the vocal folds.

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.

Computer-assisted orthognathic surgery combined with fibular osteomyocutaneous flap reconstruction to correct facial asymmetry and maxillary defects secondary to maxillectomy in childhood.

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.

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 tip or IOP based system with a mini flared tip while also providing better endothelial preservation thus favouring the use of an IOP fed system with a balanced tip.

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.

2017-03-01

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.

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.

Despite the robotic surgery is widely applied, sleeve lobectomy for lung cancer using the Da Vinci surgical system is still less performed. We described a sleeve lobectomy for adenocarcinoma located at the left lower lobe using the Da Vinci surgical system. A case of 57-year old female referred to our hospital. 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.

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.

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.

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.

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

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

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 incidents.

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

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.

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.

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.

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.

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.

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.

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.

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.

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

2016-01-01

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:27239278

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.

Scapulothoracic arthroscopy is gaining recognition among arthroscopic procedures as it is considered a relatively low morbidity procedure; also, continuing studies of this technique are making it safer. Scapulothoracic arthroscopy can be used for removal of a foreign body. This case report describes the removal of a firearm projectile using image-guided arthroscopy, highlighting the anatomical aspects and characteristics of the surgical technique. In this case, the patient recovered uneventfully, with complete remission of symptoms in 30 days, returning to his usual activities within 2 months after surgery. PMID:25480137

Synchronous B3 thymoma and lung bronchoalveolar carcinoma.

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.

[Post-traumatic complication of trans-appendiceal cystostomy: urinary peritonitis].

PubMed

Landry, J L; Dubois, R; Chaffange, P; Pelizzo, G; Dodat, H

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.

Conversion disorder is a psychiatric disorder in which psychological stress causes neurologic deficits. A 28-year-old female surgical patient had uneventful general anesthesia and emergence but developed conversion disorder 1 hour postoperatively. She reported difficulty speaking, right-hand numbness and weakness, and right-leg paralysis. Neurologic examination and imaging revealed no neuronal damage, herniation, hemorrhage, or stroke. The patient mentioned failing examinations the day before surgery and discontinuing her prescribed antidepressant medication, leading us to diagnose conversion disorder, with eventual confirmation by neuroimaging and follow-up examinations.

Uteroenteric Fistula Resulting From Fibroid Expulsion After Uterine Fibroid Embolization: Case Report and Review of the Literature

DOE Office of Scientific and Technical Information (OSTI.GOV)

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.

Introduction Nonparasitic splenic cysts are uncommon clinical entity and because of it, there is no information regarding their optimal surgical treatment. Case presentation A 41-years-old female with incidentally diagnosed nonparasitic splenic cyst which initially was asymptomatic. After two years of follow up, the patient underwent surgery; subtotal cystectomy and omentoplasty as an additional procedure. Postoperative course was uneventful. Conclusion Short and mid term results showed that near total cystectomy with omentoplasty was a safe successful procedure for treatment of epidermoid splenic cyst. PMID:19829799

A Surgery-first approach in surgical-orthodontic treatment of mandibular prognathism--a case report.

2010-01-01

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.

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

PubMed

Wang, Long; Shi, Xiang'en; Liu, Fangjun; Qian, Hai

2016-12-01

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.

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.

[Superficial sponge anesthesia in cataract surgery (with scleral tunnel incision)].

PubMed

Pham, D T; Scherer, V; Wollensak, J

1996-12-01

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 insufficient.

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.

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.

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.

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.

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.

Intraoperative fracture of phacoemulsification sleeve

PubMed Central

2010-01-01

Background We describe a case of intraoperative fracture of phacoemulsification sleeve during phacoemulsification surgery. Case presentation Phacoemulsification surgery was performed in the left eye of a 58-year-old lady with grade II nuclear sclerosis & grade I cortical cataract. Towards the end of quadrant removal, there was anterior chamber instability with impaired followability of nuclear fragments. The distal part of the fractured sleeve remained inside the anterior chamber upon removal of the phacoemulsification probe. The retained sleeve was retrieved with a pair of forceps through the corneal incision site, which did not require widening. There was no missing fragments retained intraocularly and the patient had an uneventful recovery with vision of 20/25 at three months post-operatively. Conclusion Phacoemulsification sleeve fracture is an uncommon complication. With early identification of this condition and proper management, major complications can be avoided. PMID:21118542

Recurrent uveitis and pigment dispersion in an eye with in-the-bag acrylic foldable intraocular lens.

2016-02-26

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.

Rhabdomyosarcoma is a very rare malignant tumor of the larynx which can present in a number of histologic variants. The pleomorphic variant of the tumor has been described in 16 patients to date. Being a rarity, rhabdomyosarcoma is as a rule managed according to the principle of treatment for malignant mesenchymal tumors of the head and neck, and includes radical surgery with postoperative radiotherapy and/or chemotherapy. A case is presented of a pleomorphic rhabdomyosarcoma of the vocal cord. Successfully treated by endoscopic CO2 laser cordectomy with adjuvant chemotherapy and 6-year uneventful follow up.

The purpose of this study was to characterize the safety of laparoscopic pyloromyotomy and examine the effect of resident training on the occurrence of complications. Five hundred consecutive infants who underwent laparoscopic pyloromyotomy between January 1997 and December 2005 were reviewed and analyzed. Laparoscopic pyloromyotomy was successfully completed in 489 patients (97.8%). Four hundred seventeen patients were boys (83%). Intraoperative complication occurred in 8 (1.6%) patients (mucosal perforation, 7; serosal injury to the duodenum, 1). All were immediately recognized and uneventfully repaired. Six patients (1.2%) required revision pyloromyotomy for persistent or recurrent gastric outlet obstruction. There were 7 wound complications (1.4%) and no deaths. Pediatric surgery residents performed 81% of the operations, whereas 16% were done by general surgery residents (postgraduate years 3-4). There was a 5.4-fold increased risk of mucosal perforation or incomplete pyloromyotomy when a general surgery resident rather than a pediatric surgery resident performed the operation (95% confidence interval, 1.8-15.8; P = .003). These effects persisted even after controlling for weight, age, and attending experience. The laparoscopic pyloromyotomy has an excellent success rate with low morbidity. The occurrence of complications is increased when the operation is performed by a general surgery resident, even when directly supervised by pediatric surgical faculty.

Debulking surgery for elephantiasis nostras with large ectatic podoplanin-negative lymphatic vessels in patients with lipo-lymphedema.

2014-01-01

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.

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.

Assessing the effects of ketorolac and acetazolamide on macular thickness by optical coherence tomography following cataract surgery.

2014-06-01

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.

Dodick laser phacolysis: thermal effects.

PubMed

Alzner, E; Grabner, G

1999-06-01

To gather experimental data on whether Dodick laser phacolysis leads to corneal or scleral burns. The Eye Department, County Hospital Salzburg, Salzburg, Austria. The study was done using a pulsed neodymium:YAG (Nd:YAG) laser with a wavelength of 1064 nm; energy, 10 mJ; and duration of pulses, 14 ns. The light pulse is carried by a 400 microns quartz fiber to the laser phacolysis probe. The laser light hits a titanium target inside the tip, causing an optical breakdown and thus a shock wave. The generation of both plasma and the shock disrupt the nuclear material. The temperature at the ultrasonic phaco and laser phacolysis tip was measured under air and balanced salt solution (BSS) in a test chamber and in the anterior chambers of eye-bank eyes. Ultrasonic phacoemulsification led to a difference in temperature up to 55.3 degrees C under air, 12 degrees C in BSS, and 10.9 degrees C in the anterior chamber. There was no clinical significant heat generated by the laser phacolysis tip. This initial in vitro study demonstrates that the well-known risk of the tissue heating (i.e., phaco burn) does not occur with Dodick laser phacolysis, even when the irrigation flow is slow or discontinued.

Ultrasonic-generated fluid velocity with Sovereign WhiteStar micropulse and continuous phacoemulsification.

PubMed

Steinert, Roger F; Schafer, Mark E

2006-02-01

To evaluate and compare ultrasonic turbulence created by conventional and micropulse ultrasound technology. Sonora Medical Systems, Longmont, Colorado, USA. A high-resolution digital ultrasound probe imaged the zone around a phacoemulsification tip. Doppler analysis allowed determination of flow. The fluid velocity was measured at 4 levels of ultrasound power at a constant flow, comparing the ultrasonic conditions of continuous energy to WhiteStar micropulses. In addition to the normal baseline irrigation and aspiration, fluid movement was detected directly below the phaco tip, produced by a nonlinear effect known as acoustic streaming. Acoustic streaming increased with increased phacoemulsification power for both conditions. At each of the 4 levels of power, fluid velocity away from the tip was less with micropulse technology than with continuous phacoemulsification. The demonstrated decrease in acoustic streaming flow away from the phaco tip with Sovereign WhiteStar micropulse technology compared to conventional ultrasound provides an objective explanation for clinical observations of increased stability of nuclear fragments at the tip and less turbulence in the anterior chamber during phacoemulsification. This methodology can be used to examine and compare fluid flow and turbulence under a variety of clinically relevant conditions.

Seventh-day syndrome (7DS) is an early serious complication of liver transplantation, characterized by sudden failure of a previously normally functioning liver graft ∼1 week after the surgery. Although it is an uncommon event, it has major associated mortality. As its etiology is yet to be recognized, the only currently available treatment is retransplantation. We present 3 cases of orthotopic liver transplantation recipients who had an initial uneventful recovery after surgery followed by a dramatic rise of serum liver enzyme levels ∼7 days later and hepatic failure with subsequent graft loss and death despite high-dose immunosuppressive therapy. Histologic findings showed massive centrolobular hemorrhage and hepatocellular necrosis with reduced inflammation. It is essential to review and accumulate more clinical and laboratory information to better understand this syndrome and to better prevent and treat it. Copyright © 2015 Elsevier 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.

2014-01-01

To describe the side effects and management after inadvertent injection of a dexamethasone implant (Ozurdex) into the crystalline lens. Two case reports. Two patients with macular edema due to unilateral retinal vein occlusion were scheduled for an intravitreal injection of Ozurdex. During the procedure, the implant was accidentally injected into the crystalline lens. Both patients developed cataracts during the course of several weeks and in both there was an intraocular pressure (IOP) increase, which required treatment with topical hypotensives. Macular edema improved only slightly. Cataract surgery with uneventful removal of the implant was performed 3 (case 1) and 6 months (case 2) after the injection. After inadvertent injection of Ozurdex into the crystalline lens, cataract surgery with removal of the implant should be performed as soon as possible in order to avoid IOP increase and so that the underlying condition may be treated adequately.

Laser treatment of an oral squamous papilloma in a pediatric patient: a case report.

Oral squamous papilloma is a benign proliferation of the stratified squamous epithelium, which results in a papillary or verrucous exophytic mass induced by human papilloma virus (HPV). These oral mucosa lesions are most often asymptomatic and have small progression. Laser assisted surgery is common nowadays with several advantages including successful hemostasis, devoid of sutures, wound sterilization and minimal post-operative pain and edema. The aim of this report is to present the oral squamous papilloma in a pediatric patient and its treatment with soft tissue laser. The lesion was excised with diode laser and the healing was uneventful in follow-up visit after one year. Oral squamous papillomas can be found in child's oral cavity and laser dentistry can be used by dental clinicians to treat these kinds of oral lesions and should be considered as an alternative to conventional surgery.

We present a 29-year-old woman who was admitted to the emergency department with shortness of breath. Using echocardiography, a giant multi-cystic mass was detected in the right ventricle, attached to the septal leaflet of the tricuspid valve and basal portion of the interventricular septum. Serologic tests (hydatid cyst antibody) confirmed Echinococcus infection. Lung computed tomography with intravenous contrast showed involvement of the pulmonary vasculature. The patient underwent cardiac surgery and the large cardiac cyst and the one in the right pulmonary artery branch were both removed. The tricuspid valve was also replaced by a bioprosthetic one. Albendazole was started preoperatively and was continued for six months after surgery. The patient recovered uneventfully and was followed up for one year. This is a report of a rare case of a very large cardiac hydatid cyst complicated by pulmonary embolism with attachments to both the tricuspid valve and interventricular septum.

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.

2014-01-01

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.

Mycobacterium mageritense , a rapidly growing mycobacterium, is a rare clinical pathogen. Furthermore, parotitis due to non-tuberculosis mycobacterium is very rare in adults. Herein, we report the first case of M. mageritense parotitis in an immunocompetent adult. A 40-year-old man presented with swelling in a left parotid lesion. He was diagnosed with parotitis. The culture from the parotid abscess grew M. mageritense . He was unsuccessfully treated with levofloxacin monotherapy. Trimethoprim-sulfamethoxazole was added, leading to some clinical response; however, the erythema persisted despite 14 months of antibiotic therapy. Subsequently, the skin lesion was surgically removed. The antibiotic treatment was ceased a week after surgery as the postoperative course was uneventful and the lesion had improved. No recurrence was noted at 7 months after surgery. Although extremely rare, M. mageritense can cause parotitis in immunocompetent adults, and may not be sufficiently treated with antibiotics alone.

Video-assisted thoracic surgery repair of subclavian artery injury following central venous catheterization: a new approach

2013-01-01

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

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.

Laparoscopic repair of ureter damaged during laparoscopic hysterectomy: Presentation of two cases

Ureter injuries are uncommon but dreaded complications in gynecologic surgery and a frequent cause of conversion to laparotomy. Recently, a few papers reported the repair of gynecologic ureteral injuries using laparoscopy with encouraging results. In these case reports, we aimed to present two laparoscopically repaired ureter injuries during total laparoscopic hysterectomies (TLH). In the first case, the ureter was transected during the dissection of the cardinal ligament, approximately 7 to 8 cm distal to the ureterovesical junction (UVJ), and in the second case, it was damaged approximately 10 cm distal to the UVJ. Both transections were identified during surgery. The injured ureter was repaired without converting to laparotomy or additional trocar insertion. Ureteroureterostomy was performed in both cases uneventfully. Although ureteric injury is a rare complication during TLH, it can be managed by the same surgeon laparoscopically during the same procedure. PMID:29085711

Gallstone ileus is a mechanical intestinal obstruction caused due to impaction of a large gallstone within the bowel. The ideal treatment of gallstone ileus remains controversial, with the main dilemma being between a one-stage and a two-stage surgical procedure. A 69-year old male patient presented with gallstone ileus. A one-stage procedure with enterolithotomy and primary closure of duodenal fistula was done. His immediate postoperative recovery was uneventful, but after 3 weeks of surgery, he developed respiratory complications and expired of multi-organ failure. In gallstone ileus, patient presents with symptoms of intestinal obstruction. Enterolithotomy alone remains the most common operative method, but the definitive surgical management is still under research. An intraoperative dilemma between a one-stage or two-stage surgery is difficult to resolve in absence of clear guidelines. Hence, more studies are required to come to a consensus in deciding its definitive management. PMID:28808520

To determine the relationship between cataract severity and socioeconomic status (SES). Retrospective, observational case series. A total of 1350 eyes underwent phacoemulsification cataract extraction by a single surgeon using an Alcon Infiniti system. Cataract severity was measured using phaco time in seconds. SES was measured using area-level aggregate census data: median income, education, proportion of common-law couples, and employment rate. Preoperative best corrected visual acuity was obtained and converted to logarithm of the minimum angle of resolution values. For patients undergoing bilateral surgery, the generalized estimating equation was used to account for the correlation between eyes. Univariate analyses were performed using simple regression, and multivariate analyses were performed to account for variables with significant relationships (p < 0.05) on univariate testing. Sensitivity analyses were performed to assess the effect of including patient age in the controlled analyses. Multivariate analyses demonstrated that cataracts were more severe when the median income was lower (p = 0.001) and the proportion of common-law couples living in a patient's community (p = 0.012) and the unemployment rate (p = 0.002) were higher. These associations persisted even when controlling for patient age. Patients of lower SES have more severe cataracts. Copyright © 2015. Published by Elsevier Inc.

Actinomycosis of Distal Phalanx Twenty Years after Flap Reconstruction of Index Finger: A Case Report.

PubMed

Prashant, N; Azuhairy, A

2018-03-01

Actinomycosis is a chronic granulomatous suppurative infection caused by anaerobic bacteria from genus Actinomyces which are normal flora of mouth, colon and vagina. Actinomycosis of upper extremity is rare. We report a case of actinomycosis of the distal phalanx of finger many years after flap reconstruction. The patient presented with two months' history of chronic discharging sinus from the tip of his right index finger, which had sustained a degloving injury 20 years previously. It had been treated with an anterior chest wall flap which had healed uneventfully but was bulky due to excess tissue from the donor site. Radiograph revealed osetomyelitis changes of distal phalanx. Debulking surgery with curettage of the distal phalanx was done. Wound healing was uneventful. He was treated with six weeks of metronidazole and ciprofloxacin. The discharge from the distal phalanx cultured actinomycosis odontolyticus . Histopathology of the debrided tissue showed chronic inflammation. As far as we are aware, there are no reports of actinomycosis in a flap involving the finger treated previously with a chest wall skin flap. The infection was probably dormant for many years before manifesting as a discharging sinus. Although the finger flap was bulky, it was not problematic until it started to have serous discharge. With a thorough debridement of all infected tissue, six weeks of antibiotic was adequate. Ciprofloxacin was prescribed based on discharge culture sensitivity. Metronidazole was added as actinomycosis is anaerobic. Response was prompt as patient was not immunocompromised. At follow-up six months post-surgery the finger had recovered with good function. If not for the discharging sinus, patient would probably have tolerated his bulky finger for the rest of his life.

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.

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.

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.

Decision for surgery in the management of a rare condition, childhood gallbladder polyps, and the role of ultrasonography.

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.

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.

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 report a case of a 3-year-old boy who presented with symptoms and signs of intestinal obstruction. The patient reported no previous history of abdominal surgery or trauma while clinical and radiographic examinations were not diagnostic. An open laparotomy was subsequently performed and the intraoperative findings were consistent with a congenital band extending from the antimesenteric wall of the jejunum to the root of mesentery. The band was ligated and divided with an uneventful postoperative course. Congenital bands are extremely rare. Their exact incidence is still unknown. This case, therefore, represents an unusual surgical problem in a child in which the diagnosis was clinically unexpected.

The orbit was exenterated and the dog recovered uneventfully. Histopathologic diagnosis was a primary choroidal melanoma with orbital extension, however, the behavioral and cytologic features were benign. Routine examinations postsurgically were nonremarkable. Twenty-one months after surgery the dog was euthanized for respiratory collapse with radiographic signs of metastasis. Necropsy revealed black lesions in the lung and liver. Histopathologic diagnosis was metastatic melanoma with morphology and behavior identical to the primary choroidal melanoma. This is the first definitive case of a canine choroidal melanoma with metastasis.

Orbital ultrasonography showed the mass to have a distinct border and to extend into the posterior orbit. The mass was removed via a conjunctival incision. It had a distinct capsule anteriorly, while the border of the mass was less readily identified in the posterior orbit. Histopathological examination showed the mass to be a lipoma. The dog recovered uneventfully from surgery, and no recurrence has been noted after 12 months.

Genitourinary tuberculosis still continues to plague developing countries and is a significant cause of morbidity as well as mortality in the developing world. At present, nearly 55% of the patients of genitourinary tuberculosis (GUTB) need surgical management. Owing to the presence of dense adhesions and loss of normal anatomical planes, GUTB was considered to be a contraindication to laparoscopic surgery. However, recent literature shows laparoscopy to be feasible in GUTB. Our study aimed at identifying the challenges in laparoscopic urinary tract reconstructive surgery in genitourinary tuberculosis-related urinary tract obstruction. The details of 6 patients who underwent different types of laparoscopic reconstructive surgery for genitourinary tuberculosis-related urinary tract obstruction from January 2014 to December 2015 were reviewed. Baseline characteristics, indications of surgery, type of surgery, operative duration, blood loss, and follow-up details were noted. All patients received antitubercular treatment before surgery as per the direct observed treatment short-course regimen followed in our country. We performed one bilateral laparoscopic pyeloplasty, one unilateral laparoscopic pyeloplasty, two laparoscopic ureteroneocystostomies, and two ureteroureterostomies. Difficulty was encountered during dissection owing to the presence of adhesions, but conversion to open surgery was not done in five cases. Dense adhesions adjacent to the common iliac vessels necessitated conversion to open surgery in one of the ureteroureterostomies. Stenting was done in all the patients. All patients had uneventful postoperative recovery. Functional imaging following stent removal showed unobstructed tracer flow, showing successful operative outcome. Our study showed that laparoscopic reconstructive surgery is feasible in genitourinary tuberculosis despite the presence of adhesions that may pose a challenge to dissection. This is in contrast to the previous studies which conclude that genitourinary tuberculosis is a relative contraindication to laparoscopic surgery.

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.

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.

Chylous ascites occurring after abdominal surgery is rare. Despite being potentially critical, there is no definite treatment guideline because of its rarity. Here we present a case of massive chylous ascites occurring after rectal surgery which was successfully treated with an oral fat-free elemental diet (ED). A 67-year-old man underwent low anterior resection with para-aortic lymphadenectomy for advanced rectal cancer. Early postoperative course was uneventful and the patient was discharged from hospital 10 days after surgery; however, after discharge, abdominal distension rapidly developed. Abdominal computed tomography (CT) performed 3 weeks after surgery revealed massive ascites and laboratory findings showed remarkable hypoproteinemia and lymphopenia. Urgent diagnostic paracentesis showed the ascites to be a white milky fluid containing high levels of triglycerides (564 mg/dl), leading to a diagnosis of chyloperitoneum. Daily nutrition of the patient was entirely with a fat-free ED (30 kcal/kg/day of Elental(®), Ajinomoto Pharmaceutical Co. Ltd, Tokyo, Japan). After the initiation of oral Elental(®), abdominal distension, hypoproteinemia, and lymphopenia gradually improved. Abdominal CT performed 7 weeks after surgery showed no ascitic fluid in the abdomen, and thereafter a normal diet was initiated. Since then, no relapse of chyloperitoneum has been proven. As a result, the chylous ascites was successfully treated in the outpatient clinic.

Spleen-preservation has recently been emphasized in benign and borderline malignant pancreatic diseases requiring distal pancreatectomy. Reports to suggest that laparoscopic distal pancreatectomy is feasible and safe have been increasingly published. Robotic surgical system has been introduced and is expected to provide unique advantages in laparoscopic surgery. However, robot-assisted pancreatic surgery has not yet been performed by many surgeons. A 45-year-old female patient with abdominal discomfort was found to have pancreatic cyst in the body of the pancreas. Mucinous cystic tumor of the pancreas was the most favourable preoperative diagnosis. She underwent spleen-preserving laparoscopic distal pancreatectomy by using da Vinci surgical robot system. Splenic artery and vein were so tightly adherent to the pancreatic cyst that segmental resection of splenic vessels was required. Postoperative course was uneventful. She was able to come home in 5 days after surgery. Postoperative follow up color doppler ultrasound scan, taken on 2 weeks after surgery, showed minimal fluid collection around surgical field and no evidence of splenic infarction with good preservation of splenic perfusion. Robot-assisted spleen preserving distal pancreatectomy is thought to be feasible and safe. Several unique advantages of robotic system are expected to enhance safer and more precise surgical performance in near future. More experiences are mandatory to confirm real benefit of robot surgery in pancreatic disease.

The aim is to present a patient with severe bilateral corneal complications after long-term antiglaucoma treatment with 1% pilocarpine hydrochloride (Pilokarpin, Pliva, Zagreb, Croatia) and its management. A patient with narrow-angle glaucoma treated with 1% topical pilocarpine hydrochloride eye drops for the last twenty years complained of impaired vision, intermittent visual haloes and eye redness. Ophthalmologic examination showed bilateral band keratopathy, peripheral laser iridotomy, medicamentous myosis, brown nuclear cataract, and synchysis scintillans of his right eye. Band keratopathy was thought to have resulted from the presence of the preservative phenylmercuric nitrate in the pilocarpine hydrochloride eye drops. Treatment of the patient consisted of two separate procedures for both eyes, i.e. phaco trabeculectomy and six months later corneal procedure including abrasion of corneal epithelium followed by removal of the superficial stromal calcium deposits by means of a 3.75% ethylenediaminetetraacetic (EDTA) solution. After phaco trabeculectomy, visual acuity was 0.8 on both eyes. Bilateral visual improvement with visual acuity 1.0 was recorded after corneal treatment with EDTA. In conclusion, one must be aware of preservative complications in long-term topical use, such as band keratopathy that can be visually incapacitating. Surgical treatment using EDTA is safe and effective treatment for band keratopathy.

To suggest a new surgical approach for posterior opacities or persistent Descemet membrane (DM) detachment in failed deep anterior lamellar keratoplasty (DALK) and to report the outcome of Descemet membrane endothelial keratoplasty (DMEK) in a series of patients with DALK failure. In this retrospective case series of patients who underwent DMEK for failed DALK at Toronto Western Hospital, 4 patients with failed DALK who underwent DMEK surgery were included. In all 4 cases, big bubble formation during initial DALK surgery had failed and the surgical technique was converted to manual dissection using the Melles technique. In 2 cases, the descemetorhexis in DMEK surgery was performed manually, and in 2 cases, the descemetorhexis was performed with the assistance of the femtosecond laser. Four eyes of 4 patients aged 70 ± 4 years were included. Average follow-up time was 9 ± 5 months. Indications for DALK surgery were corneal dystrophy in 2 patients and corneal scars in the other 2. DALK failure was due to persistent DM detachment that created a double chamber in 2 patients and due to posterior lamellar haze in the other 2. After DMEK surgery, 2 patients had graft detachment and required rebubbling. In 1 patient, the DMEK scroll was attached after 1 rebubble attempt, and in the other patient, a second rebubble attempt was needed. The final visual acuities were 20/40, 20/50, 20/70, and 20/200 (because of dense cataract). All procedures were uneventful. DMEK surgery may be effective in managing DALK failure.

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.

Objective: 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. Methods: 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. Results: 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. Conclusions: 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. PMID:24741382

2014-01-01

Intestinal obstruction is a common complication associated with Meckel’s diverticulum in adults. The diverticulum itself or its fibrous band can lead to an intestinal volvulus, intussusceptions, or closed-loop obstructions, which require surgery. The incarceration of Meckel’s diverticulum in either inguinal or femoral hernia sacs (Littre’s hernia) is another, less common, etiology underlying intestinal obstruction. This case report describes a 45-year-old man who had an obstruction associated with a Meckel’s diverticulum that passed through a congenital defect in the mesocolon into the right subphrenic space. The patient, who had not undergone abdominal surgery previously, came to the emergency room with acute onset of intermittent epigastric pain and abdominal distention. Computed tomography images showed the presence of a segment of the small bowel and a diverticulum in the right subphrenic space and paracolic gutter. The twisted mesentery and the dilated loops of the proximal small bowel were indicative of an intestinal volvulus and obstruction. Meckel’s diverticulum complicated by a transmesocolic internal hernia was diagnosed, and this condition was confirmed during emergency surgery. The patient’s postoperative recovery was uneventful. This case report highlights another presentation of Meckel’s diverticulum, that is, in combination with a transmesocolic internal hernia. This etiology may lead to an intestinal volvulus and necessitate early surgery. PMID:25309093

A 38-year-old woman with advanced keratoconus initially developed Urrets-Zavalia Syndrome (UZS) in the left eye after deep anterior lamellar keratoplasty. During the uneventful surgery, a 7-mm-wide pupil unresponsive to light was noticed. On the first postoperative day, intraocular pressure (IOP) was elevated up to 45 mmHg with shallow anterior chamber (AC). A peripheral iridotomy in 2 o’clock position was conducted and a fixed combination of brinzolamide 1% and timolol 0.5% was administered topically. In the subsequent postoperative period, IOP was successfully reduced, but the patient reported severe photophobia, glare, and decreased vision. Twelve months after surgery, her best-corrected visual acuity (BCVA) was 20/200, the fixed-dilated pupil persisted, iris was atrophic, and lens opacities were detected. She was submitted for phacoemulsification cataract surgery combined with iridoplasty using the closed chamber slipping suture technique. Three months after surgery, her BCVA was 20/25, pupil diameter remained stable at 4 mm, and glare symptoms were significantly reduced. A very adequate cosmetic outcome was also achieved. Iridoplasty in postkeratoplasty patient with unilateral UZS was effective in improving patient's visual function disability and restoring residual anisocoria. This technique can be applied as a single procedure or combined with another one for the management of UZS. PMID:29118500

Bariatric restrictive and malabsorptive operations are being carried out in most countries laparoscopically. Carbon dioxide or gas embolism has never been reported in obese patients undergoing bariatric surgery. We report a case of carbon dioxide embolism during laparoscopic sleeve gastrectomy (LSG) in a young super obese female patient. Early diagnosis and successful management of this complication are discussed. An 18-year-old super obese female patient with enlarged fatty liver underwent LSG under general anesthesia. During initial intra-peritoneal insufflation with CO2 at high flows through upper left quadrant of the abdomen, she had precipitous fall of end-tidal CO2 and SaO2 % accompanied with tachycardia. Early suspicion led to stoppage of further insufflation. Clinical parameters were stabilized after almost 30 min, while the blood gas analysis was restored to normal levels after 1 h. The area of gas entrainment on the damaged liver was recognized by the surgeon and sealed and the surgery was successfully carried out uneventfully. Like any other laparoscopic surgery, carbon dioxide embolism can occur during bariatric laparoscopic surgery also. Caution should be exercised when Veress needle is inserted through upper left quadrant of the abdomen in patients with enlarged liver. A high degree of suspicion and prompt collaboration between the surgeon and anesthetist can lead to complete recovery from this potentially fatal complication. PMID:21772696

Technical Report of Successful Deployment of Tandem Visual Tracking During Live Laparoscopic Cholecystectomy Between Novice and Expert Surgeon.

2016-09-20

With the recent advances in eye tracking technology, it is now possible to track surgeons' eye movements while engaged in a surgical task or when surgical residents practice their surgical skills. Several studies have compared eye movements of surgical experts and novices and developed techniques to assess surgical skill on the basis of eye movement utilizing simulators and live surgery. None have evaluated simultaneous visual tracking between an expert and a novice during live surgery. Here, we describe a successful simultaneous deployment of visual tracking of an expert and a novice during live laparoscopic cholecystectomy. One expert surgeon and one chief surgical resident at an accredited surgical program in Lubbock, TX, USA performed a live laparoscopic cholecystectomy while simultaneously wearing the visual tracking devices. Their visual attitudes and movements were monitored via video recordings. The recordings were then analyzed for correlation between the expert and the novice. The visual attitudes and movements correlated approximately 85% between an expert surgeon and a chief surgical resident. The surgery was carried out uneventfully, and the data was abstracted with ease. We conclude that simultaneous deployment of visual tracking during live laparoscopic surgery is a possibility. More studies and subjects are needed to verify the success of our results and obtain data analysis.

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/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 utilisation of facilities and increase cataract surgical coverage need to be developed. PMID:16547315

Lung Transplantation From Donors After Previous Cardiac Surgery: Ideal Graft in Marginal Donor?

2017-05-01

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.

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.

Coarsened Exact Matching of Phaco-Trabectome to Trabectome in Phakic Patients: Lack of Additional Pressure Reduction from Phacoemulsification

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

Objective To report on general anesthesia management in amyotrophic lateral sclerosis. Case Presentation and Intervention A 47-year-old man presented with fracture of the humerus. The patient was diagnosed with amyotrophic lateral sclerosis. General anesthesia was induced with propofol, rocuronium and remifentanil. After uneventful surgical repair, TOF (train-of-four) ratio reached >0.90 at the end of operation. However, muscle strength and tidal volume were inadequate. After sugammadex 2 mg kg−1 i.v. was given, the patient was extubated 120 s later. Conclusion This case highlights that rocuronium and sugammadex can be used safely in patients with amyotrophic lateral sclerosis undergoing surgery with general anesthesia. PMID:23075763

This submission presents a case of scoliosis in a patient with established Dandy-Walker anomaly of the brain. A retrospective review of the patient’s case notes was undertaken and the limited literature on this subject reviewed. The 13-year-old girl presented with a stiff right thoracic scoliosis typical of adolescent idiopathic scoliosis. The scoliotic segment also presented with significant lordosis. She had facial and truncal dysmorphism characteristic of Dandy-Walker complex and her brain images confirmed the diagnosis. She underwent scoliosis surgery by the posterior approach uneventfully. In conclusion scoliosis is hitherto unreported in the Dandy-Walker complex. The results of intervention appear satisfactory. PMID:29354751

Acute Esophageal Necrosis: “Black Esophagus”

Weigel, Tracey L.

2007-01-01

Acute esophageal necrosis (AEN) is an uncommon event. We report a case of an 84-year-old female with a giant paraesophageal hernia who presented with coffee ground emesis and on esophagogastroduodenoscopy (EGD) demonstrated findings consistent with acute esophageal necrosis and a giant paraesophageal hernia with normal-appearing gastric mucosa. She was managed conservatively with bowel rest, parenteral nutrition, and continuous intravenous proton pump inhibitor (PPI). After significant improvement in the gross appearance of her esophageal mucosa, surgery was performed to reduce her giant paraesophageal hernia. The patient's postoperative course was uneventful, and she was discharged home on postoperative day 6, tolerating a normal diet. The percutaneous endoscopic gastrostomy (PEG) tube was removed in clinic 2 months postoperatively. PMID:17651583

Surgical stapling techniques are widely used in gastrointestinal surgery. These procedures are excellent in convenience and safety. We describe here a new practical application of the surgical disposable stapler, Auto Suture Premium Plus CEEA 34 circular stapler, for the operative drainage of a large symptomatic pancreatic pseudocyst. A 68 year-old man underwent an operative cystogastrostomy using this instrument. His post-operative recovery was uneventful. He is free from symptoms, and abdominal tomography shows complete disappearance of the cystic cavity. We believe that this is the first clinical paper that reports on the stapled cystogastrostomy. This instrument is very useful for creating a stapled cystogastrostomy, similar to one created in the standard open approach.

The introduction of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) brought about significant advancement in the field of bronchoscopy. The major indications for EBUS-TBNA are lung cancer staging and diagnosis of mediastinal lymphadenopathy. This procedure is minimally invasive and cost saving, and no complications have been described in large-scale studies. In this report, we present a case of empyema, lung abscess, and mediastinal abscess that developed in a patient undergoing EBUS-TBNA; the patient subsequently recovered uneventfully after aggressive surgical debridement and antimicrobial therapy.

Synchronous adenocarcinomas of the colon presenting as synchronous colocolic intussusceptions in an adult

PubMed Central

2012-01-01

Intussusception is uncommon in adults. To our knowledge, synchronous colocolic intussusceptions have never been reported in the literature. Here we described the case of a 59-year-old female of synchronous colocolic intussusceptions presenting as acute abdomen that was diagnosed by CT preoperatively. Laparotomy with radical right hemicolectomy and sigmoidectomy was undertaken without reduction of the invagination due to a significant risk of associated malignancy. The final diagnosis was synchronous adenocarcinoma of proximal transverse colon and sigmoid colon without lymph nodes or distant metastasis. The patient had an uneventful recovery. The case also emphasizes the importance of thorough exploration during surgery for bowel invagination since synchronous events may occur. PMID:23241170

Epulis fissuratum refers to tissue growth into the oral cavity, located over the alveolar ridges or the soft tissues of the vestibular sulcus. Trauma and irritation are important aetiological factors for epulis fissuratum and lesions arise in areas of persistent mucosal injury. This report presents a case of a 68-year old male patient with two soft tissue hyperplastic growths seen in the buccal vestibule in the lower anterior region. These lesions were removed using an Er,Cr:YSGG laser. The healing was uneventful and no suture or analgesic was required. The histopathological report confirmed the presurgical diagnosis. No relapse was observed till one year after surgery.

Gastric volvulus is an abnormal rotation of all or a part of the stomach around one of its axes. It is a rare cause of intestinal obstruction in children. This anomaly can be primary, due to abnormalities of the gastric ligaments, or secondary to other congenital malformations. We report on the cases of five children treated between January 1994 and December 2011, four boys and one girl, with a medium age of 7 months. Diagnosis was based on clinical features, particularly in the upper gastrointestinal Rx contrast study, which confirmed the diagnosis. Four out of the five children underwent laparoscopic surgery with fixation of the stomach. A diaphragmatic hernia was associated in one case. Antireflux surgery was performed in three cases, and a diaphragmatic defect was closed in one case. The follow-up was uneventful after a medium period of 7 years. good knowledge of this anomaly is the guarantee of early diagnosis and optimum treatment to ameliorate the prognosis.

2014-05-01

Minilaparoscopy is an attractive approach for hysterectomy due to advantages such as reduced morbidities and enhanced cosmesis. However, it has not been popularized due to the lack of suitable instruments and high technical demand. We aim to highlight the first case of minilaparoscopic hysterectomy reported in Asia and the use of a new integrated energy platform, Thunderbeat. We would like to propose an alternative method of instrumentation, so as to improve the feasibility and safety of minilaparoscopic hysterectomy. The first minilaparoscopic hysterectomy in Singapore was successfully completed using the alternative instrumentation and new energy platform. There was no conversion or complication during the surgery. The patient recovered uneventfully. To our knowledge, this is the first report on the use of such alternative instrumentation. This approach in instrumentation and the new energy platform will improve the feasibility and speed of the surgery and ensure safety in our patients. © 2014 The Authors.

Patel, Seena; Perry, Maureen Munnelly; Spolarich, Ann Eshenaur

2016-01-01

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.

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

2014-01-01

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.

Video-assisted minithoracotomy for blunt diaphragmatic rupture presenting as a delayed hemothorax.

2014-01-01

Diaphragmatic ruptures after blunt trauma are rare life-threatening conditions. Most of them occur on the left-sided hemidiaphragm with herniation or associated organ injuries after a motor vehicle accident. We present an unusual case of blunt diaphragmatic rupture resulting in a delayed hemothorax. A 62-year-old man presented with acute dyspnea that initiated while straining to pass stool. He had a bruise on the lower back region of his right thorax after a slip-and-fall accident 7 days previously. Chest computed tomographic scans revealed a right-sided hemothorax without any evidence of herniation or associated organ injuries. Emergency surgery was performed through a video-assisted minithoracotomy. During surgery, we identified a diaphragmatic laceration with a severed blood vessel originating from the right superior phrenic artery. The lesion was repaired with interrupted horizontal mattress sutures. The total amount of bleeding was approximately 2000 mL. The patient had an uneventful recovery with no further bleeding episodes.

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.

Bronchopleural fistulae (BPF) are communications between the bronchial tree and the pleural spaces. This anomaly is associated with significant morbidity and mortality, and its management in some patients remains a major therapeutic challenge for clinicians. Here we report a case involving a 62-year-old man with chronic empyema associated with multiple BPF caused by severe necrotizing pneumonia with parapneumonic effusion in the left lower lobe. His BPF were treated by decortication and retrograde surgical sealing with Gore-Tex plugs that were sutured to the parenchyma and bronchus and reinforced by glue and an intercostal muscle flap. The air leakage stopped immediately after surgery and the chronic empyema resolved. His subsequent postoperative course was uneventful, and he was discharged 14 days after surgery. At the 8-month follow-up visit, stable surgical outcomes with no BPF recurrence were observed. In summary, we described a novel and easy surgical technique for the repair of intractable peripheral BPF in select patients. PMID:26793385

Adrenergic crisis due to pheochromocytoma - practical aspects. A short review.

PubMed

Juszczak, Kajetan; Drewa, Tomasz

2014-01-01

The definitive therapy in case of pheochromocytoma is complete surgical resection. Improper preoperative assessment and medical management generally places the patient at risk for complications, resulting from an adrenergic crisis. Therefore, it is crucial to adequately optimize these patients before surgery. Optimal preoperative medical management significantly decreases morbidity and mortality during the tumor resection. This review addresses current knowledge in pre- and intraoperative assessment of a patient with pheochromocytoma. Before surgery the patient is conventionally prepared with α-adrenergic blockade (over 10-14 days) and subsequently, additional β-adrenergic blockade is required to treat any associated tachyarrhythmias. In preoperative assessment, it is obligatory to monitor arterial blood pressure, heart rate, and arrhythmias and to restore the blood volume to normal. In conclusion, due to the pathophysiological complexity of a pheochromocytoma, the strict cooperation between the cardiologist, endocrinologist, surgeon and the anaesthesiologist for an uneventful outcome should be achieved in patients qualified for the surgical removal of such a tumor.

Primary chest wall abscess occurring after blunt chest trauma is rare. We present the case of a 50-year-old woman who presented with a swelling in her left breast. The patient had experienced blunt chest trauma 2 months back. Needle aspiration revealed pus formation in the patient's chest. Computed tomography revealed a mass in the lower region of the left mammary gland, with thickening of the parietal pleura and skin and fracture of the fifth rib under the abscess. Following antibiotic administration and irrigation of the affected region, surgical debridement was performed. During surgery, we found that the pectoralis major muscle at the level of the fifth rib was markedly damaged, although the necrotic tissue did not contact the mammary gland. We diagnosed the lesion as a chest wall abscess that occurred in response to blunt chest trauma. Her postoperative course was uneventful. There has been no recurrence for six months after surgery.

To report the clinical features, management, and outcome of 7 cases of culture-proven multidrug-resistant Enterobacter postoperative endophthalmitis following cataract surgery. Medical records of 7 cases of acute postoperative endophthalmitis after uneventful cataract surgery were reviewed. Details regarding age, gender, visual acuity and clinical features at presentation, microbiological profile, treatment interventions, and visual acuity and clinical features at 1 week, 1 month, and 3 months follow-up were collected. All patients reported decreased visual acuity and pain as presenting symptoms. All patients were resistant to intravitreal antibiotics such as vancomycin (1 mg/0.1 mL) and ceftazidime (2.25 mg/0.1 mL). Culture of aqueous and vitreous sample was positive for Enterobacter aerogenes and sensitive to co-trimoxazole, cefoperazone-sulbactam, imipenem-meropenem, and piperacillin-tazobactem. Two patients with panophthalmitis and no perception of light underwent evisceration. Three patients had visual acuity of ≥6/24 at the final follow-up. Multidrug-resistant Enterobacter acute postoperative endophthalmitis has a poor prognosis if not intercepted early.

We herein report our technique for laparoscopic esophageal myotomy combined with Collis gastroplasty and Nissen fundoplication for severe esophageal stenosis. Our patient had experienced vomiting since childhood, and his dysphagia had gradually worsened. He was referred to our department for surgery because of resistance to pneumatic dilation. He was diagnosed with a short esophagus based on the findings of a preoperative upper gastrointestinal series and GI endoscopy. After exposing the abdominal esophagus, esophageal myotomy around the esophago-gastric junction (EGJ) was undertaken to introduce an esophageal bougie into the stomach. Then, stapled wedge gastroplasty was performed, and a short and loose Nissen fundoplication was performed. In addition, the bulging mucosa after myotomy was patched using the Dor method. The patient's postoperative course was uneventful. Most patients with esophageal stricture require subtotal esophagectomy. Laparoscopic surgery for patients with benign esophageal stricture refractory to repeated pneumatic dilation is challenging. However, our current procedure might abrogate the need for invasive esophagectomy for the surgical management of severe esophageal stenosis.

One hundred and fifty-three cats undergoing surgery in seven veterinary practices in Great Britain were studied. They were randomly allocated to receive either 10-20 microg/kg buprenorphine or 0.4 mg/kg butorphanol with acepromazine before anaesthesia with propofol, Saffan or thiopentone and isoflurane or halothane. Routine monitoring was undertaken. Pain and sedation were assessed blind using a four point (0-3) simple descriptive scale (SDS) at 1, 2, 4, 8 and 24h. Pain and sedation data were compared using non-parametric statistical tests and continuous data using t tests or analysis of variance (ANOVA). Anaesthesia and surgery were uneventful, and cardiorespiratory data were within normal limits. After surgery, overall, more cats had pain score 0 after buprenorphine and more had pain score 3 after butorphanol (P=0.0465). At individual time points, more cats had lower pain scores after buprenorphine at 2 (P=0.040) and 24 (P=0.036)h. At 24h 83% after buprenorphine and 63% after butorphanol had pain score 0 (P<0.04). Buprenorphine provided better and longer lasting postoperative analgesia than butorphanol. Copyright 2009 ISFM and AAFP. Published by Elsevier Ltd. All rights reserved.

The aim of this study was to review our experience in the management of traumatic rupture of the aortic isthmus, to evaluate the results of surgery and endovascular exclusion and to develop an adequate therapeutic strategy based on the existence and severity of associated injuries. A series of 37 patients presenting posttraumatic aortic rupture associated with other severe lesions was collected from 2000 to 2012. There were 33 males and four females, mean age 38 years. In this series, 25 patients underwent surgical treatment and 12 endovascular exclusion. Six patients died during or after surgery. Overall mortality was 16% (24% in the surgery group). The postoperative period was uneventful in all patients treated with the endovascular procedure. Postoperative computed tomography controls at one week, 1 month and 12 months showed good positioning of the stent without endoleakage. Traumatic aortic rupture is often the result of a severe high-energy chest trauma. Other serious injuries are often associated. Results of immediate surgical repair are associated with high morbidity and mortality. The advent of endovascular treatment has revolutionized the treatment of traumatic aortic rupture, especially in patients with a high surgical risk. Copyright © 2013.

2017-01-18

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.

Circumportal Pancreas-a Must Know Pancreatic Anomaly for the Pancreatic Surgeon.

Circumportal pancreas is a rare congenital pancreatic anomaly with encasement of the portal vein and/or the superior mesenteric vein by pancreatic tissue. It is often overlooked on cross-sectional imaging studies and can be encountered during pancreatic surgery. Pancreatic head resection with circumportal pancreas is technically difficult and bears an increased risk of postoperative pancreatic fistula. A retrospective chart review of our data base for all patients who had undergone pancreatic head resection between 2004 and 2015 was performed. We identified six patients out of 1102 patients who had undergone pancreatic head surgery in the study period. CT-scan and MRI were never able to identify circumportal pancreas prior to surgery. The right hepatic an artery derived from the superior mesenteric artery in four cases (67%). Additional resection of the pancreatic body was always performed. Postoperative course was uneventful in all cases without occurrence of pancreatic fistula. Circumportal pancreas is a rare entity every pancreatic surgeon should be aware of. It is difficult to identify on cross-sectional imaging studies. A right hepatic artery arising from the superior mesenteric artery should raise suspicion of circumportal pancreas. Additional pancreatic tissue resection should be performed during pancreatic head resections to avoid pancreatic fistula.

Prognosis of locally advanced esophageal cancer is poor. The greatest prognostic factor of locally advanced esophageal cancer is a local control. We experienced a case of T4 locally advanced thoracic esophageal cancer who was successfully resected without any combined resection after multimodality therapy. A male in 75-year-old. was diagnosed with type 3 locally advanced upper thoracic esophageal cancer whose metastatic right recurrent laryngeal lymph node invaded into the trachea. Definitive chemoradiation therapy(CRT)was performed, leading to a significant shrinkage of the main tumor, but T4 lesion remained. Next, adding DCF therapy(docetaxel, CDDP and 5-FU), a relief of T4 was finally obtained. Then, salvage surgery with subtotalesophagectomy and retrosternalesophagealreconstruction with gastric tube was performed, resulting in R0 resection without any combined resection. The postoperative course was uneventful, and the patient has been alive without recurrence for 1 year after surgery. In locally advanced cancer, focusing on T4 downstaging, it is significantly important in terms of safety, curativity and organ preservation to perform surgery after a sure sign of T4 relief by multimodality therapy.

Relationship between cataract severity and socioeconomic status.

2013-12-01

To determine the relationship between cataract severity and socioeconomic status (SES). Retrospective, observational case series. A total of 1350 eyes underwent phacoemulsification cataract extraction by a single surgeon using an Alcon Infiniti system. Cataract severity was measured using phaco time in seconds. SES was measured using area-level aggregate census data: median income, education, proportion of common-law couples, and employment rate. Preoperative best corrected visual acuity was obtained and converted to logarithm of the minimum angle of resolution values. For patients undergoing bilateral surgery, the generalized estimating equation was used to account for the correlation between eyes. Univariate analyses were performed using simple regression, and multivariate analyses were performed to account for variables with significant relationships (p < 0.05) on univariate testing. Sensitivity analyses were performed to assess the effect of including patient age in the controlled analyses. Multivariate analyses demonstrated that cataracts were more severe when the median income was lower (p = 0.001) and the proportion of common-law couples living in a patient's community (p = 0.012) and the unemployment rate (p = 0.002) were higher. These associations persisted even when controlling for patient age. Patients of lower SES have more severe cataracts. Copyright © 2013 Canadian Ophthalmological Society. Published by Elsevier Inc.

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 operation. Conclusions: Both methods, topical and retro bulbar block had similar impression in cataract surgery regarding analgesia and patient satisfaction. However, in non-complicated cataract surgeries with short duration, topical anesthesia may be the preferable method, because of non-invasiveness, appropriate analgesia, patient satisfaction and hemodynamic stability.

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).

Tubal sterilization with Essure inserts has become a prevalent alternative to laparoscopic sterilization because of its minimal invasiveness. It is a well-tolerated ambulatory procedure that provides reliable permanent contraception without the risks associated with laparoscopic surgery and general anesthesia. Correct positioning of the Essure device is necessary to achieve the fibrotic reaction induced by the polyethylene terephthalate fibers, subsequently resulting in tubal occlusion usually within 3 months. After uneventful procedures with satisfactory bilateral placement, only the correct position of the devices needs to be confirmed at follow-up. The imaging techniques used to asses Essure devices may vary depending on the country and its recommendations. The gold standard test to ascertain tubal occlusion remains the hysterosalpingography but after uneventful procedures, vaginal-ultrasound proved to be a reliable alternative to confirm the proper position of the inserts. Radiologists have been increasingly confronted to post procedural evaluations and despite the efficiency rate of the Essure device, its use still exposes to a low risk of complications and malfunctions such as unwanted pregnancies, device misplacement, tubal or uterine perforation, and chronic pelvic pain. Unintended pregnancies are mostly due to patient or physician non-compliance and misinterpretation of post procedural examinations by radiologists which emphasizes the importance of their training in Essure device assessment. This pictorial review discusses the imaging methods used to asses Essure implants and illustrates the possible complications related to them.

Wolff-Parkinson-White (WPW) syndrome is a rare pre-excitation syndrome which develops when atrioventricular conduction occurs through a pathologic accessory pathway known as the bundle of Kent instead of atrioventricular node, hence resulting in tachycardia. Patients with WPW syndrome may experience various symptoms arising from mild-to-moderate chest disease, palpitations, hypotension, and severe cardiopulmonary dysfunction. These patients are most often symptomatic because of cardiac arrhythmias. In this case report, we present an uneventful anesthetic management of a pregnant patient with WPW syndrome undergoing cesarean delivery. A 23-year-old American Society of Anesthesiologists class 2 pregnant patient was diagnosed with WPW syndrome. Her preoperative 12-lead electrocardiogram showed a sinus rhythm at 82 beats per minute, a delta wave, and a short PR interval. After an uneventful surgery, sugammadex 2mg/kg was administered as a reversal agent instead of neostigmine. Then she was discharged to her obstetrics service. Serious hemodynamic disorders may occur in patients with WPW syndrome due to development of fatal arrhythmias. Neostigmine used as a reversal agent in general anesthesia can trigger such fatal arrhythmias by leading changes in cardiac conduction. We believe that sugammadex, which is safely used in many areas in the scope of clinical practice, can be also used for patients diagnosed with WPW syndrome. Copyright © 2016 Elsevier Inc.

Femoral neck fractures in the elderly comprise a significant number of orthopedic surgical cases at a major trauma center. These patients are immediately incapacitated, and surgical fixation can help increase mobility, restore independence, and reduce morbidity and mortality. However, operative treatment carries its own inherent risks including infections, deep vein thromboses, and intraoperative cardiovascular collapse. Cerebrovascular stroke is a relatively uncommon occurrence after hip fractures. We present 2 cases with unusual postoperative medical complication after cemented hip hemiarthroplasty for femoral neck fracture that will serve to illustrate an infrequent but very serious complication. Case 1 was a 73-year-old man with a Garden IV femoral neck fracture who underwent a right hip unipolar cemented hemiarthroplasty under general anesthesia. After uneventful surgery, he developed neurological deficits, and a postoperative noncontrast head computed tomography showed a right medial thalamic infarct. Case 2 was an 82-year-old man with a Garden IV femoral neck fracture who underwent a right hip unipolar cemented hemiarthroplasty under general anesthesia. After uneventful surgery, the patient became hemodynamically unstable. A postoperative noncontrast head computed tomography showed a large evolving left middle cerebral artery stroke. General anesthesia in the setting of decreased cardiac function (decreased ejection fraction and output) carries the risk for ischemic injury to the brain from decreased cerebral perfusion. Risk factors including advanced age, history of coronary artery disease, atherosclerotic disease, and atrial fibrillation increase the risk for perioperative stroke. Furthermore, it is known that during the cementing of implants, microemboli can be released, which must be considered in patients with preoperative heart disease. As a result, consideration of using a noncemented implant or cementing without pressurizing in this clinical scenario should be an important aspect of the preoperative plan in an at-risk patient. Further studies are needed that can elucidate a causal relationship.

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.

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.

Novel platforms based on the application of bacterial cell systems as factories for production of new bioproducts open avenues and dramatically expand the catalogue of existing biomaterials. Herein, we designed the strategy based on in vivo production of extracellular Pseudomonas fluorescens GK13 (PhaZGK13) depolymerase to degrade previously biosynthesized polyhydroxyalkanotes (PHAs) or to obtain 3-hydroxyalkanoic acids (HAs). With this aim, extracellular PhaZGK13 was produced in recombinant strains and the optimal conditions for controlled release of HAs and oligomers by growing cells were set up with a particle suspension of (14)C-labelled PHA, being maximal after 24h of incubation. Genetic modification of key factors involved in fatty acids metabolism revealed the influence of an active β-oxidation pathway on the extracellular degradation of PHA and subsequent HAs isolation. The highest HAs production was obtained using Pseudomonas putida KT2442 fadB mutant (0.27mg/mL) due to the reduced ability of this strain to metabolize the degradation products. The system was applied to produce new added value HAs harboring thioester groups in the side chain from the functionalized mcl-PHA, PHACOS. Remarkably, hydrolyzed PHACOS showed greater potential to inhibit Staphylococcus aureus(T) growth when compared to that of degradation products of non functionalized polyhydroxyoctanoate-co-hexanoate P(HO-co-HH).

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.

Technical Report of Successful Deployment of Tandem Visual Tracking During Live Laparoscopic Cholecystectomy Between Novice and Expert Surgeon

PubMed Central

Baronia, Benedicto C

2016-01-01

With the recent advances in eye tracking technology, it is now possible to track surgeons’ eye movements while engaged in a surgical task or when surgical residents practice their surgical skills. Several studies have compared eye movements of surgical experts and novices and developed techniques to assess surgical skill on the basis of eye movement utilizing simulators and live surgery. None have evaluated simultaneous visual tracking between an expert and a novice during live surgery. Here, we describe a successful simultaneous deployment of visual tracking of an expert and a novice during live laparoscopic cholecystectomy. One expert surgeon and one chief surgical resident at an accredited surgical program in Lubbock, TX, USA performed a live laparoscopic cholecystectomy while simultaneously wearing the visual tracking devices. Their visual attitudes and movements were monitored via video recordings. The recordings were then analyzed for correlation between the expert and the novice. The visual attitudes and movements correlated approximately 85% between an expert surgeon and a chief surgical resident. The surgery was carried out uneventfully, and the data was abstracted with ease. We conclude that simultaneous deployment of visual tracking during live laparoscopic surgery is a possibility. More studies and subjects are needed to verify the success of our results and obtain data analysis. PMID:27774359

Recombinant human growth/differentiation factor-5 (rhGDF-5) is being evaluated as a candidate therapy in support of periodontal regeneration. The objective of this study was to evaluate periodontal wound healing/regeneration following the application of rhGDF-5 on a particulate beta-tricalcium phosphate (beta-TCP) carrier using an established defect model. Bilateral 4 x 5 mm (width x depth), one-wall, critical-size, intrabony periodontal defects were surgically created at the mandibular second and fourth pre-molar teeth in 15 Beagle dogs. Unilateral defects in five animals received rhGDF-5/beta-TCP (Scil Technology GmbH); five animals received beta-TCP solo; and five animals served as sham-surgery controls. Contralateral sites received treatments reported elsewhere. The animals were sacrificed following an 8-week healing interval for histological examination. Clinical healing was generally uneventful. Sites implanted with rhGDF-5/beta-TCP exhibited greater enhanced cementum and bone formation compared with beta-TCP and sham-surgery controls; cementum regeneration averaged (+/- SD) 3.83 +/- 0.73 versus 1.65 +/- 0.82 and 2.48 +/- 1.28 mm for the controls (p<0.05). Corresponding values for bone regeneration height averaged 3.26 +/- 0.30 versus 1.70 +/- 0.66 and 1.68 +/- 0.49 mm (p<0.05), and bone area 10.45 +/- 2.26 versus 6.31 +/- 2.41 and 3.00 +/- 1.97 mm(2) (p<0.05). Cementum regeneration included cellular/acellular cementum with or without a functionally oriented periodontal ligament. A non-specific connective tissue attachment was evident in the sham-surgery control. Controls exhibited mostly woven bone with primary osteons, whereas rhGDF-5/beta-TCP sites showed a noticeable extent of lamellar bone. Sites receiving rhGDF-5/beta-TCP or beta-TCP showed some residual beta-TCP granules apparently undergoing biodegradation without obvious differences between the sites. Sites receiving beta-TCP alone commonly showed residual beta-TCP granules sequestered in the connective tissue or fibrovascular marrow. rhGDF-5/beta-TCP has a greater potential to support the regeneration of the periodontal attachment. Long-term studies are necessary to confirm the uneventful maturation of the regenerated tissues.

Ventricular fibrillation caused by electrocoagulation in monopolar mode during laparoscopic subphrenic mass resection

2010-01-01

Background Monopolar is usually a safe and effective electrosurgical unit used in laparoscopic general surgery. However, it can cause adverse outcomes and even cardiac arrest. We present a video of laparoscopic subphrenic mass resection using monopolar coagulation during which ventricular fibrillation occurred and from which the patient was successfully resuscitated. Methods Our patient was a 39-year-old man who was admitted to our institution for treatment of a liver mass. The mass was located in the left subphrenic region and was 3.31 cm × 2.7 cm according to B ultrasound. He had had a spleen resection after a car accident 14 years before. He was otherwise healthy and a physical examination was negative. He was scheduled for “laparoscopic exploration, mass resection.” General anesthesia was induced and the operation began. While dissecting the mass from the diaphragm there was some bleeding; monopolar electrocoagulation with 68 W was performed upon which ventricular fibrillation occurred. The operation was stopped and closed-chest compression began immediately. Defibrillation (200-J shock) was performed in 1 min and rhythm returned to sinus. Results The operation was resumed carefully and uneventfully. The patient was sent to the postoperative acute care unit and was extubated 10 min after operation. The patient recovered uneventfully without any signs of permanent cardiac injury and was discharged on postoperative day 3. The final pathology was accessory spleen. Conclusions We present a video of a patient who experienced ventricular fibrillation during laparoscopic surgery which was successfully defibrillated leaving no permanent cardiac injury. We assume the reason for the ventricular fibrillation was the low-frequency leakage current from electrocoagulation which may be conducted by Swan-Ganz catheter to the heart. It is important that we be familiar with the character of electrosurgical unit when performing laparoscopic surgery. We should be careful when using an electrosurgical unit near the cardiac region, especially when the patient has an indwelling catheter. We recommend performing hemostasis in bipolar mode or use an ultrasonic scalpel if bleeding is close to the heart. Also, an easily available defibrillator should be ready for use.

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.

Abdominal aortic aneurysms (AAAs) are very rare in Marfan syndrome. We present a case with a young nonsmoking and normotensive male with Marfan syndrome, who developed an infrarenal AAA that presented with rupture to the retroperitoneal cavity causing life-threatening bleeding shock. The patient had acute aortic surgery and survived. Five months before this incident, the patient had uneventful elective aortic root replacement (ad modum David) due to an enlarged aortic root. At that time, his abdominal aorta was assessed with a routine ultrasound scan that showed a normal-sized abdominal aorta. This documents that the aneurysm had evolved very rapidly despite young age and absence of risk factors. Copyright © 2018 Elsevier Inc. All rights reserved.

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

Summary This is a retrospective review of the record charts. A joint study by maxillofacial and neurosurgical units, department of surgery, Korle Bu Teaching Hospital, Accra, Ghana, a tertiary and premier health care centre. Seventeen consecutive patients with various cranial defects treated using prefabricated acrylic methyl methacrylate implants. The cranioplasty on all the patients took place at an average of about 12 months after the initial surgery. These included complications during and after surgery. X-ray views of the skull, ranging from true lateral to anterior-posterior, were taken at follow-up and examined to ascertain the stability of the graft by looking out for any adverse bony changes around it or loosening of any of the steel sutures securing it to the skull. A total of 17 patients (5 males and 12 females) with a mean age of 30.4 years were treated. Follow-up period ranged from 9 months to two years. In all cases the surgical procedure was uneventful and the cosmetic results were good. There was no significant change in the size and shape of the preformed methyl methacrylate implant after autoclaving. Cranioplasty using prefabricated acrylic methyl methacrylate implants apart from being affordable also ensure shorter operative time and good aesthetic result.

To report the successful surgical management (open mitral commissurotomy, OMC) of mitral stenosis (MS), incorporating heart-beating cardiopulmonary bypass (CPB), in a 1-year-old dog. Clinical case. One-year-old Cairn Terrier with MS. Diagnosis of MS was confirmed by means of 2-dimensional, continuous-wave and color-flow Doppler echocardiography. Surgery was performed through a left intercostal thoracotomy. CPB was initiated and the heart was kept beating. The fused commissures of the mitral valve were incised to free the cusps of the valve. Left intercostal thoracotomy allowed easy observation of the mitral orifice during heart-beating OMC. Persistent bleeding from the atriotomy site required a second surgical procedure after which the dog had an uneventful recovery. Echocardiography at 2 weeks and 1 year postoperatively indicated substantial improvement in left ventricular filling (pressure half-time=187 ms before surgery, 105 ms [2 weeks] and 110 ms [1 year] after surgery). Enlargement of the left atrium resolved; however, moderate mitral valve regurgitation was still present. MS can be successfully treated by OMC, facilitated by use of CPB. Substantial improvement in cardiac function was evident by ultrasound and Doppler examination postoperatively. OMC under heart-beating CPB should be considered for the treatment of MS in the dog.

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.

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.

A 27-year-old man with recurrent right lower quadrant pain was admitted to our hospital. Ultrasonography and computed tomography examination of the abdomen revealed a target sign in the ascending colon, which was compatible with the diagnosis of cecal intussusception. The intussusception was spontaneously resolved at that time, but it relapsed 6 mo later. The patient underwent a successful colonoscopic disinvagination; there was no evidence of neoplastic or inflammatory lesions in the colon and terminal ileum. The patient underwent laparoscopic surgery for recurring cecal intussusception. During laparoscopy, we observed an unfixed cecum on the posterior peritoneum (i.e. a mobile cecum). Thus, we performed laparoscopic appendectomy and cecopexy with a lateral peritoneal flap using a barbed wound suture device. The patient's post-operative course was uneventful, and he continued to do well without recurrence at 10 mo after surgery. Laparoscopic cecopexy using a barbed wound suture device is a simple and reliable procedure that can be the treatment of choice for recurrent cecal intussusception associated with a mobile cecum.

The purpose of this study is to compare the outcomes following femtosecond laser-assisted deep anterior lamellar keratoplasty (DALK) with 75% of stromal dissection (predescemetic group) and femtosecond laser-assisted DALK using big-bubble technique with total stromal resection (descemetic group) for the treatment of keratoconus. Twenty eyes of 17 patients with keratoconus were studied. There were 10 eyes of 9 patients in predescemetic group and 10 eyes of 8 patients in descemetic group. The postoperative best-corrected visual acuity (BCVA), manifest refraction, keratometry, endothelial cell density (ECD), and central corneal thickness (CCT) were analyzed. All surgeries were performed uneventfully. At 1 year after surgery, the BCVA, corneal astigmatism, keratometry, CCT, and ECD between two groups were not statistically significant (all P > 0.05). However, the mean manifest refraction was -9.43 ± 7.44 diopter (D) and -1.03 ± 1.13D in predescemetic and descemetic groups, respectively, which was statistically significant between two groups (P < 0.05). The results of BCVA and corneal astigmatism, keratometry, ECD, and CCT were comparable between two groups. However, the mean postoperative manifest refraction was lower in descemetic group.

An anomalous muscle bundle crossing the right atrial cavity represents a pathological finding with unproved clinical significance. This congenital anomaly may be difficult to recognize via echocardiography and could be confused with other intra-cavitary lesions. We report a case of a 53-year-old female presented to the cardio-vascular service with acute superior vena cava syndrome and sub-massive pulmonary embolism. The patient underwent venography confirming superior vena cava stenosis. A ventilation/perfusion lung scan showed two sizable perfusion defects due to pulmonary embolism. MRI and echocardiography imaging demonstrated right atrium mass. Surgery was then carried out using standard cardiopulmonary bypass; right atrial muscle bundle was excised and superior vena cava reconstruction was performed. The patient was discharged uneventfully and remains symptom-free at two years follow-up. In cases of nonmalignant pathology of superior vena cava syndrome, appropriate studies should be conducted to exclude potential congenital abnormalities such as this anomalous muscle bundle in the right atrium. Open heart surgery is a viable treatment option in select cases. Published by Elsevier Inc.

Extra-anatomic bypass for recurrent abdominal aortic and renal in-stent stenoses following radiotherapy for neuroblastoma.

2009-04-01

We describe the case of an 11-year-old girl with an abdominal neuroblastoma which was operated and intraoperatively irradiated nine years ago. After six years, she developed stenoses of the infrarenal abdominal aorta and both renal arteries. Initial treatment of the stenosed vessels comprised endovascular balloon dilatations and repeated stent-graft implantations, including drug eluting stents. However, severe in-stent stenoses occurred during follow-up and the girl developed acute renal failure. Open surgery was performed with two extra-anatomic bypasses, a thoracic-to-abdominal aortic bypass and a left iliac-to-renal bypass, on an urgent basis. The postoperative course was uneventful and the patient was discharged home two weeks after the operation with full recovery of renal function. We conclude that endovascular stent-graft placement in children can only be a palliative treatment due to outgrowing of the stent-graft and the potential risk of re-stenosis, especially after a history of irradiation. Vascular surgery with placement of extra-anatomic bypasses will provide a definite treatment.

General anesthesia combined with epidural anesthesia for thoracotomy due to spontaneous pneumothorax was given to a pregnant woman at 21st week of gestation. She was premedicated intravenously with famotidine 20 mg and metoclopramide 10 mg. Mepivacaine 1% was administered through a thoracic epidural catheter. General anesthesia was induced by thiamylal 225 mg, vecuronium 8 mg and fentanyl 100 mcg, and maintained by sevoflurane, vecuronium and fentanyl. Endobronchial intubation with a 35Fr Bronchocath double-lumen tube was successful and one-lung ventilation was commenced to maintain the end-expiratory CO2 pressure at 30 to 35 mmHg with Sp(O2) remaining 100%. Ephedrine 16mg (in 4mg increments) was required to maintain systolic blood pressure above 100 mmHg. After the surgery, ropivacaine 0.2% was administered through the catheter. There were no clinical signs of fetal distress during the perioperative period. Postoperative pregnancy and delivery were uneventful. We succeeded in the anesthetic management by avoiding hypoxia, hypercapnia, hypocapnia and hypotension during the surgery.

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.

Ultrasound-guided urinary bladder biopsy through a urinary catheter in a bitch.

Lopez, Julio; Norman, Brian C

2014-01-01

A 34.4 kg 5 yr old spayed female mixed-breed dog was presented for evaluation of a urinary bladder mass. The dog had a recent onset of hematuria and stranguria but otherwise appeared to be healthy. Abdominal ultrasound revealed a mass in the urinary bladder. The dog was sedated and a 10-French rubber catheter that had the blunt end removed was passed from the urethra to the urinary bladder. Using ultrasound guidance, ellipsoid cup biopsy forceps were advanced through the rubber catheter to the urinary bladder mass and biopsies were successfully obtained. The dog was discharged from the hospital a few hours after the procedure. Histopathology of the mass was consistent with polypoid cystitis. Follow-up surgical removal of the polyp was uneventful, and histopathology confirmed the presurgical biopsy diagnosis. Procurement of urinary bladder biopsies through a urinary catheter with ultrasound guidance was used as a minimally invasive alternative to either cystoscopy or surgery in a bitch. Use of this technique achieved a diagnosis without the need for specialized endoscopic equipment, anesthesia, or surgery.

A case of a 22-year old soldier, with a history of pain in the leg during heavy exercise, which desisted at rest, was presented. One day before admission, the patient had felt an extreme exertion-induced pain in his right leg which had not lessenned at rest. At the same time, the patient noticed persistent severe leg edema. On physical examination, the intracompartmental pressure was 62 mmHg (> 30 mmHg). The patient was urgently operated on, and fasciotomy according to Mubarak was used. At second surgery, the debridement of the muscles of the posterior group of the leg, and the evacuation of hemathoma from the anterior and lateral group of the right leg muscles were perfomed. Postoperative recovery was uneventful. Fasciotomy wounds were closed within 14 days of the surgery. The complete physical treatment was done. Follow-up examinations 1, 3, and 6 months afterwards were satisfactory. The soldier completed his compulsory military service without any sequelae. Laboratory results were normal. Overlooked, unrecognized or surgically untreated compartment syndrome can cause severe damage, including even the loss of the extremity.

A 63-year-old man, who had undergone total gastrectomy and Roux-en-Y reconstruction for gastric cancer 10 years previously, was admitted to our hospital with complaints of abdominal pain, palpable abdominal tumor, and hematemesis. On admission, the abdominal tenderness was improving and no abdominal tumor was palpable. Mild inflammatory changes and anemia were noted on blood examination. Abdominal computed tomography revealed a tumor with a layered structure in the left abdomen. The patient was diagnosed with intestinal obstruction secondary to intussusception, and surgery was performed. Retrograde intussusception was found at the site of the Y anastomosis. We conducted manual reduction using the Hutchinson procedure. The intestinal color after the reduction was good, and no intestinal resection was required. Postoperative recovery was uneventful, and the patient was discharged 12 days after surgery. Reports of jejunal intussusception after total gastrectomy with Roux-en-Y reconstruction are relatively rare. Here, we report a case of jejunal intussusception after total gastrectomy with Roux-en-Y reconstruction.

Vascular Ehlers-Danlos Syndrome (vEDS) is caused by heterozygous mutations in COL3A1 and is characterized by fragile vasculature and hollow organs, with a high risk of catastrophic events at a young age. During pregnancy and delivery, maternal mortality rates up until 25% have been reported. However, recent pedigree analysis reported a substantial lower pregnancy-related mortality rate of 4.9%. Here, we describe an extended vEDS family with multiple uneventful pregnancy outcomes. In the proband, a 37-year-old woman, DNA-analysis because of an asymptomatic iliac artery dissection revealed a pathogenic mutation in COL3A1 (c.980G>A; p. Gly327Asp). She had had three uneventful vaginal deliveries. At the time of diagnosis, her 33-year-old niece was 25 weeks pregnant. She had had one uneventful vaginal delivery. Targeted DNA-analysis revealed that she was carrier of the COL3A1 mutation. Ultrasound detected an aneurysm in the abdominal aorta with likely a dissection. An uneventful elective cesarean section was performed at a gestational age of 37 weeks. The 40-year-old sister of our proband had had one uneventful vaginal delivery and an active pregnancy wish. Cascade DNA-screening showed her to carry the COL3A1 mutation. Computed Tomography Angiography (CTA) of her aorta revealed a type B dissection with the most proximal entry tear just below the superior mesenteric artery. Pregnancy was therefore discouraged. This familial case illustrates the complexity and challenges of reproductive decision-making in a potentially lethal condition as vEDS, and highlights the importance of a multidisciplinary approach. Moreover, it suggests that previous pregnancy-related risks of vEDS may be overestimated. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The purpose of this study was to estimate and compare the temperatures of two different anterior chamber solutions at the corneal endothelial level during phacoemulsification. An ophthalmic viscosurgical device (OVD) and balanced salt solution (BSS) were compared using the finite element method (FEM). The thermal properties of an OVD (IAL-F) and BSS were studied in an experimental setting. A computer-aided design model of ocular anatomy was created in two dimensions. The phaco needle was considered to be the only source of heat generation. Then, the FEM was used to demonstrate the transient temperature distribution in the two ocular models at 10, 20, 30, 40, 50 and 60 s. In these models, the anterior chamber was filled with IAL-F (IAL-F model) or BSS (BSS model). The heat generation rate of the phaco needle was 0.0004 cal/s/mm(2). The maximum corneal endothelial temperatures for the two models at 60 s were 52.67 and 41.57 degrees C, respectively. The experimental IAL-F model showed fewer changes in temperature for any given time and location. At larger distances from the heat source, less temperature variation was detected. Phacoemulsification is a potential heat-generating procedure performed between the delicate anterior chamber structures. During this procedure, IAL-F protects the endothelium against heat better than BSS. Copyright 2009 S. Karger AG, Basel.

Laparoscopic surgery is normally performed under general anaesthesia, but regional techniques have been found beneficial, usually in the management of patients with major medical problems. Encouraged by such experience, we performed a feasibility study of segmental spinal anaesthesia in healthy patients. Twenty ASA I or II patients undergoing elective laparoscopic cholecystectomy received a segmental (T10 injection) spinal anaesthetic using 1 ml of bupivacaine 5 mg ml-1 mixed with 0.5 ml of sufentanil 5 microg ml-1. Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery. The patients were reviewed 3 days postoperatively by telephone. The spinal anaesthetic was performed easily in all patients, although one complained of paraesthesiae which responded to slight needle withdrawal. The block was effective for surgery in all 20 patients, six experiencing some discomfort which was readily treated with small doses of fentanyl, but none requiring conversion to general anaesthesia. Two patients required midazolam for anxiety and two ephedrine for hypotension. Recovery was uneventful and without sequelae, only three patients (all for surgical reasons) not being discharged home on the day of operation. This preliminary study has shown that segmental spinal anaesthesia can be used successfully and effectively for laparoscopic surgery in healthy patients. However, the use of an anaesthetic technique involving needle insertion into the vertebral canal above the level of termination of the spinal cord requires great caution and should be restricted in application until much larger numbers of patients have been studied.

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.

This report describes a patient with a perihilar mass and mediastinal lymphadenopathy mimicking advanced lung cancer. The patient, a 45-year old regular smoker, was admitted to hospital for dyspnea and tachyarrhythmia, and during hospitalization he was diagnosed with severe rheumatic mitral valve stenosis (MVS) and aortic regurgitation as well as pulmonary venous hypertension. Surgical valve replacement and removal of an atrial thrombus was delayed considerably by diagnostic work-up for suspected malignancy. After cardiac surgery had been performed, recovery was uneventful. On follow-up 1 year later, echocardiography showed well-functioning prosthetic mitral and aortic valves, and normal findings on chest X-ray. Perihilar masses and mediastinal lymphadenopathy presented in this case constitute infrequent yet established findings in MVS, resulting from pulmonary venous congestion and hypertension, and focal lymphedema.

The acute onset of peritoneal signs and shock in a 7-year-old boy who had been hit in the epigastrium by a log-seesaw mandated surgical treatment. Enhanced computed tomography (CT) demonstrated complete laceration of the pancreas as well as duodenal injury, and a duodenoduodenostomy with distal pancreaticogastrostomy was subsequently performed. Temporary external drainage of the stomach and distal pancreas led to an uneventful recovery in the early postoperative period. Although the patient's postoperative development was appropriate for his age, the orifice of the distal pancreas spontaneously closed 2.5 years following surgery. We present this report to stress the fact that every effort should be made to preserve the pancreas following abdominal injury in children.

A 58-yr-old female with primary biliary cirrhosis underwent an uncomplicated orthotopic liver transplantation. Elevated liver function tests 2 months post-transplantation were evaluated with Doppler ultrasound and a hepatic artery stricture was documented. The hepatic artery stenosis was treated with angioplasty. She developed hemobilia 1 d after the procedure, which was confirmed by angiography. Emergent exploratory laparotomy revealed a pseudoaneurysm at the hepatic artery anastomosis. The pseudoaneurysm was resected and the proper hepatic artery of the graft was anastomosed to the splenic artery of the host using preserved homograft. Her post-operative course was uneventful and liver function tests returned to normal quickly after the surgery. This report will discuss the unusual nature of this complication, and review the problem of hemobilia and pseudoaneurysms in liver transplant recipients.

Benzocaine-induced methaemoglobinaemia: a case study.

PubMed

Bittmann, Stefan; Krüger, Carsten

Benzocaine is a widely used topical anaesthetic and has been reported to cause toxic methaemoglobinaemia in otherwise healthy individuals with no predisposing risk factors. This article reports on a rare case of benzocaine-induced methaemoglobinaemia following adenotonsillectomy in a 5-year-old girl. Topical benzocaine was applied orally for the relief of postoperative wound pain on the eighth postoperative day. Two hours after application, generalized cyanosis, mild dyspnoea and some degree of agitation developed. The methaemoglobin level was 38.5%. Treatment with methylene blue was initiated immediately. Symptoms completely disappeared 4 hours after initiation of methylene blue therapy. The further course was uneventful. Therefore, all health professionals should be aware that topical anaesthetics after surgery can induce methaemoglobinaemia in children, even after a prolonged interval, and especially when applied on wound surfaces.

A 37-year-old patient presented with a self-limiting episode of moderate haemoptysis. Contrast-enhanced chest computed tomography showed a tortuous and dilated right bronchial artery arising from the descending aorta at the level of T6. Therapeutic angiography was attempted, but in the presence of spinal artery arising from the bronchial artery in question, selective embolization was contraindicated due to risk of spinal cord ischaemia. After a multidisciplinary meeting, it was decided to attempt surgery to ligate this pathological artery. We performed minimally invasive robot-assisted ligation of this pathological artery. The postoperative course was uneventful with good clinical and radiological outcome at 3-month follow-up. A minimally invasive approach provides a real alternative to embolization and could be a therapeutic option.

We present a 76-year-old patient who had ocular trauma with dehiscence of the wound and scleral rupture with a prolapsed iris, ciliary body, intraocular lens, and vitreous after uneventful cataract surgery with a self-sealing sclerocorneal tunnel incision. General anesthesia was not possible because the patient had a history of lung cancer with extensive emphysema and unstable coronary disease. Local retrobulbar or peribulbar anesthesia was not considered because of the risk for further extrusion of intraocular contents. Topical anesthesia was applied with a 10.0 mm x 2.5 mm cellulose sponge soaked in oxybuprocaine 0.4% (Novesine) placed under the upper and lower lid for 20 minutes. Surgical repair of a 14.0 mm scleral wound was achieved without complication or pain during the procedure.

2005-01-01

Acute appendicitis is the most common non-obstetric reason of abdominal pain in the pregnancy, causing significant increase of maternal and fetal morbidity and mortality. This is a case report of a patient in the third trimester of pregnancy in whom perforated appendicitis caused purulent peritonitis. She was operated as an emergency case and cesarean section was performed. After the surgery and antibiotic administration according to drug susceptibility test, her postoperative course was uneventful. Delayed diagnosis of the acute appendicitis leads to increased rate of appendicular perforation, with numerous maternal and fetal complications. In cases of suspected appendicitis during pregnancy, surgical exploration is indicated, either by laparoscopy or laparotomy. Laparotomy is the method of choice in cases after 20 weeks of pregnancy and whenever signs of diffuse peritonitis are present.

Bleeding during gonioscopy after deep sclerectomy.

2003-10-01

To show a new complication after deep sclerectomy (DS). We described two eyes of two patients with open-angle glaucoma and cataract who were operated on of an uneventful phacoemulsification and DS with SK-gel implantation. Bleeding during gonioscopic examination occurred in both eyes 7 and 8 months after combined surgery. The blood originated from the vessels around the Descemet window, and was probably due to manipulation or rocking of the goniolens. Pressure was immediately applied to the gonioscopic lens and the hyphema was interrupted. These cases show the presence of new vessels around the Descemet window after DS with SK-gel. Bleeding from the Descemet window vessels can occur during gonioscopy even months after DS. We recommend conducting a careful gonioscopic examination in patients who have undergone DS to avoid this complication.

A 59-year-old man with metastatic an esophageal tumor from hepatocellular carcinoma (HCC) presented with progressive dysphagia. He had undergone liver transplantation for HCC three and a half years prevously. At presentation, his radiological and endoscopic examinations suggested a submucosal tumor in the lower esophagus, causing a luminal stricture. We performed complete resection of the esophageal metastases and esophagogastrostomy reconstruction using the da Vinci robotic system. Recovery was uneventful and he was been doing well 2 mo after surgery. α-fetoprotein level decreased from 510 ng/mL to 30 ng/mL postoperatively. During the follow-up period, he developed a recurrent esophageal stricture at the anastomosis site and this was successfully treated by endoscopic esophageal dilatation. PMID:21765971

Azygos vein aneurysm is very rare and is usually found incidentally because of its clinical silence. We report a case of recurrent pleural effusion caused by an azygos vein aneurysm in a patient with moderate mitral valve regurgitation (MR) and tricuspid valve regurgitation (TR). Since valve disease is considered a significant precipitating factor for both dyspnoea and pleural effusion, we decided to study the aetiologies of these conditions concomitantly. Azygos vein aneurysm resection in combination with tricuspid and mitral valve repair using cardiopulmonary bypass was performed successfully through a right anterior thoracotomy. The postoperative course was uneventful, and the patient reported improved exercise capacity. © The Author 2016.

2013-05-01

In oral, cranio, and maxillofacial surgery, a close relationship among the bone, nerves, and blood vessels can be regularly observed. Surgical procedures for the removal of dental implants have the potential to cause vascular injury and bleeding in the floor of the mouth and internal anterior region of the mandible. Furthermore, conventional osteotomy techniques always require extensive protection of adjacent soft tissue because cutting is not limited to bone and could easily affect other tissues when applied improperly. We report the removal by means of piezosurgery of a malpositioned osseointegrated implant that had previously caused a sublingual hematoma during its insertion. The postoperative course was uneventful, no bleeding, infection, or hematoma formation was noted and the patient reported 100% resolution of all symptoms. Copyright © 2013 Elsevier Inc.

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.

Toxic anterior segment syndrome caused by autoclave reservoir wall biofilms and their residual toxins.

To identify etiology of toxic anterior segment syndrome (TASS) after uneventful phacoemulsification. EyeMD Laser and Surgery Center, Oakland, California. Retrospective case series. Patient charts with TASS were reviewed. Reservoirs of 2 autoclaves associated with these cases were cultured for bacterial contamination. Cultures were performed on 23 other autoclave reservoirs at surgery centers in the local area. The main outcome measures were the incidence of TASS and prevalence of bacterial biofilm contamination of autoclave reservoirs. From 2010 to 2013, 11 935 consecutive cataract surgeries were performed at 1 center by multiple surgeons with no reported TASS. Between January 1, 2014, and January 15, 2015, 10 cases of TASS occurred out of 3003 cataract surgeries; these patients' charts were reviewed. Cultures of 2 Statim autoclave reservoir walls grew Bacillus species, Williamsia species, Mycobacterium mucogenicum, and Candida parapsilosis. Scanning electron microscopy of reservoir wall sections showed prominent biofilm. The 2 autoclaves were replaced in January 2015. Subsequently, 2875 cataract surgeries were performed with no reported TASS (P < .001, χ 2 test). Eighteen of 23 additional regional autoclaves were also contaminated with bacterial biofilms. Toxic anterior segment syndrome was strongly associated with bacterial biofilm contamination of autoclave reservoirs. An etiological mechanism might involve transport of heat-stable bacterial cell antigens in the steam with deposition on surgical instrumentation. Data suggest widespread prevalence of bacterial biofilms on fluid-reservoir walls, despite adherence to manufacturer guidelines for cleaning and maintenance. Prevention or elimination of autoclave fluid-reservoir biofilms might reduce the risk for postoperative TASS.

2014-03-01

To evaluate the posterior capsule opacification (PCO) rates in three different modern standard intraocular lenses (IOL) and analyse the related cost. Retrospective study of medical records from 1527 patients who underwent uneventful cataract surgery by phacoemulsification with posterior chamber implantation of either AcrySof SN60 (n = 375), Akreos Adapt (n = 350) or Tecnis Acryl IOL (n = 801). All surgeries were performed by the same surgeon using the same surgical technique and equipment. Primary end-point was neodymium:yttrium-aluminium-garnet (Nd:YAG) capsulotomy for visual impairment secondary to PCO. Cost of IOL material and Nd:YAG capsulotomy for PCO was then evaluated and compared between the IOLs. Mean follow-up was 41.5 months, and the only statistically significant variable of developing PCO was IOL type and individual follow-up time. Nd:YAG capsulotomy was performed in 7.47% in the AcrySof group, 17.71% in the Akreos group and 3.75% in the Tecnis group. Average cost for Nd:YAG capsulotomy per surgery was €18.75 in the AcrySof SN60 group, €44.25 in the Akreos Adapt group and €9.25 in the Tecnis Acryl group. The combined cost of cataract surgery and PCO treatment was €9.81 higher in for the Akreos Adapt group than the other two combined. This retrospective study shows that the risk of PCO and Nd:YAG capsulotomy is significantly higher in hydrophilic Akreos IOL compared with both AcrySof and Tecnis hydrophobic IOLs. The increased risk of PCO in the hydrophilic IOL is related to higher total average costs for cataract surgery. © 2012 The Authors.

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.

Elevated prothrombin time on routine preoperative laboratory results in a healthy infant undergoing craniosynostosis repair: Diagnosis and perioperative management of congenital factor VII deficiency.

Congenital factor VII deficiency is a rare bleeding disorder with high phenotypic variability. It is critical that children with congenital Factor VII deficiency be identified early when high-risk surgery is planned. Cranial vault surgery is common for children with craniosynostosis, and these surgeries are associated with significant morbidity mostly secondary to the risk of massive blood loss. A two-month old infant who presented for elective craniosynostosis repair was noted to have an elevated prothrombin time (PT) with a normal activated partial thromboplastin time (aPTT) on preoperative labs. The infant had no clinical history or reported family history of bleeding disorders, therefore a multidisciplinary decision was made to repeat the labs under general anesthesia and await the results prior to incision. The results confirmed the abnormal PT and the case was canceled. Hematologic workup during admission revealed factor VII deficiency. The patient underwent an uneventful endoscopic strip craniectomy with perioperative administration of recombinant Factor VIIa. Important considerations for perioperative laboratory evaluation and management in children with factor VII deficiency are discussed. Anesthetic and surgical management of the child with factor VII deficiency necessitates meticulous planning to prevent life threatening bleeding during the perioperative period. A thorough history and physical examination with a high clinical suspicion are vital in preventing hemorrhage during surgeries in children with coagulopathies. Abnormal preoperative lab values should always be confirmed and addressed before proceeding with high-risk surgery. A multidisciplinary discussion is essential to optimize the risk-benefit ratio during the perioperative period. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

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

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.

2014-01-01

Aim: 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. Background: 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. Materials and Methods: 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. Results: 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. Conclusion: 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 general anesthesia. PMID:25886230

We report a case of spontaneous Descemet’s membrane sweating of aqueous humor during a manual deep anterior lamellar keratoplasty (DALK) without perforation of Descemet’s membrane. An 81-year-old female developed a neurotrophic central ulcer with descemetocele in the right eye, and her visual acuity was count fingers at 30 cm. She was unresponsive to medical treatment, and an uneventful manual DALK was performed. Six months after surgery, unaided visual acuity improved to 6/30. Seven months after surgery, the patient had a decrease in visual acuity to count fingers in the same eye. She was diagnosed as having corneal melting with a central descemetocele in the previous lamellar graft. A repeat manual DALK graft was performed. Lamellar dissection was performed starting from the edge of descemetocele, proceeding to the corneal periphery and maintaining the surgical plane of the previous DALK. During the surgical procedure, continuous and localized sweating of aqueous through Descemet’s membrane was observed in the area of the descemetocele. After drying of the recipient bed, no visible perforation of Descemet’s membrane was found. After removal of the previous DALK graft, a new stromal lamellar graft was sutured. The surgery was concluded without complications. One day after surgery, the graft was clear, with no detachment of Descemet’s membrane. If Descemet’s membrane sweating is observed during DALK and there is no visible perforation, the reason may be a hidden micron perforation in an intact Descemet’s membrane. It is recommended to continue with surgery maintaining maximum diligence and low intraocular pressure to prevent extension of micron perforation. PMID:23055660

OBJECTIVE Intraventricular choroid plexus cysts are unusual causes of acute hydrocephalus in children. Radiological diagnosis of intraventricular choroid plexus cysts is difficult because they have very thin walls and fluid contents similar to CSF and can go undetected on routine CT studies. METHODS This study reports the authors' experience with 5 patients affected by intraventricular cysts originating from the choroid plexus. All patients experienced acute presentation with rapid neurological deterioration, sometimes associated with hypothalamic dysfunction, and required urgent surgery. In 2 cases the symptoms were intermittent, with spontaneous remission and sudden clinical deteriorations, reflecting an intermittent obstruction of the CSF pathway. RESULTS Radiological diagnosis was difficult in these cases because a nonenhanced CT scan revealed only triventricular hydrocephalus, with slight lateral ventricle asymmetry in all cases. MRI with driven-equilibrium sequences and CT ventriculography (in 1 case) allowed the authors to accurately diagnose the intraventricular cysts that typically occupied the posterior part of the third ventricle, occluding the aqueduct and at least 1 foramen of Monro. The patients were managed by urgent implantation of an external ventricular drain in 1 case (followed by endoscopic surgery, after completing a diagnostic workup) and by urgent endoscopic surgery in 4 cases. Endoscopic surgery allowed the shrinkage and near-complete removal of the cysts in all cases. Use of neuronavigation and a laser were indispensable. All procedures were uneventful, resulting in restoration of normal neurological conditions. Long-term follow-up (> 2 years) was available for 2 patients, and no complications or recurrences occurred. CONCLUSIONS This case series emphasizes the necessity of an accurate and precise identification of the possible causes of triventricular hydrocephalus. Endoscopic surgery can be considered the ideal treatment of choroid plexus cysts in children.

Introduction: The ideal management strategy for patients presenting late with transposition of great arteries (TGA), intact ventricular septum (IVS), and regressed left ventricle (LV) is not clear. Primary switch, two-stage switch, and Senning operation are the options. Left ventricular retraining prior to arterial switch by ductal stenting may be effective, but the experience is very limited. Methods: Five of six children aged 3–6 months with TGA-IVS and regressed LV underwent recanalization and transcatheter stenting of ductus arteriosus. The ductal stent was removed during arterial switch surgery. Results: The procedure was successful in 5/6 patients. All the patients had totally occluded ductus and needed recanalization with coronary total occlusion hardware. The ductus was dilated and stented with coronary stents. In all the patients, there was significant luminal narrowing despite adequate stent placement and deployment. Two patients needed reintervention for abrupt closure of the stent. Ductal stenting resulted in left ventricular preparedness within 7–14 days. One patient died of progressive sepsis after 14 days of stenting, even though the LV was prepared. Four patients underwent successful uneventful arterial switch surgery. During surgery, it was observed that the mucosal folds of duct were protruding through the struts of the stent in one patient. Conclusions: Ductal stenting is a good alternative strategy for left ventricular retraining in TGA with regressed LV even in patients with occluded ducts. PMID:21976872

Retrograde gastroesophageal intussusception after peroral endoscopic myotomy in a patient with achalasia cardia: A case report.

Retrograde gastroesophageal intussusception (RGEI) is a relatively rare gastrointestinal (GI) disorder in which a portion of the stomach wall invaginates into the esophagus. More recently, peroral endoscopic myotomy (POEM) has emerged as an endoscopic alternative to surgical myotomy for achalasia, and, to the best of our knowledge, our case is the first RGEI after POEM to be reported. A 22-year-old male was presented with a history of vomiting, intractable retching and hematemesis for 3 days. He had a history of achalasia and underwent POEM 3 years ago caused by symptoms of severe dysphagia to solid and liquid. Initially, the patient was diagnosed with a blood-filled esophagus, and the mid esophagus was occluded with a ball-like mass, however, the final diagnosis of RGEI was made by thoracotomy. A therapeutic strategy of conservative treatment and left transthoracic surgery were applied. The surgery and post operative course were uneventful, and he remained asymptomatic 1 year after operation. POEM is a reliable and minimally invasive endoscopic method for esophageal achalasia. Early recognition and severity of RGEI are essential to decrease the unwanted complications. Upper GI series, esophagogastroduodenoscopy and computed tomography scan are helpful for diagnostic purposes of RGEI. Conservative treatment, endoscopic intervention, and surgery are the mainstay of treatments for RGEI. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

Introduction: The necessity for complex and multidisciplinary approach of “border” surgical pathology has unanimously been agreed upon for such a long period of time, its advantages becoming even more obvious in rare, particular cases. Patients and methods: We report the case of a 39 year-old man diagnosed with lymphangiomatosis back in his childhood. He is admitted with a giant pseudotumoral scrotal mass presenting an important scrotal enlargement (40/35 cm). Physical examination, blood tests, ultrasound, IVP, abdominal and chest CT, psychiatric and plastic surgery evaluation established the diagnosis: peno-scrotal lymphedema with gigantic hydrocele and depressive disorder. Taking into account the important enlargement of the scrotum associated with the alteration of the local skin, we decided to form a mixed surgical team: urology - plastic and reconstructive surgery. We performed bilateral surgical therapy of hydrocele with partial excision and eversion of sac edges, excision of peno-scrotal skin and subcutaneous tissue surplus. At the end we made a reconstruction by using a partial-thickness graft from the normal skin of the left thigh. Results: Spinal anaesthesia was sufficient in order to perform a qualitative complex surgery. Intra and postoperative course was uneventful with minimal blood loss. Conclusion: Rare cases like this one clearly reveal the advantages of a multidisciplinary surgical team by combining usual surgical procedures from different specialities that could lead to spectacular results.

2009-03-01

The compromised nature of the residual interradicular bone after extraction of periodontally hopeless maxillary molars often requires a sinus elevation procedure to ideally place the implants to accept future prosthesis. Maxillary sinus elevation surgery is a procedure used to increase the volume of bone mass so that dental implants can be placed. This article documents a sinus floor elevation technique through an extraction socket in a 65-year-old white male with chronic inflammation to increase the bone mass after the extraction of a periodontally involved maxillary molar tooth. Computerized tomography revealed an increased thickness of the sinus membrane, which was attributed to possible chronic sinus inflammation and periodontal inflammation. After consultation with the Department of Otolaryngology, it was diagnosed as chronic inflammation without any contraindication for sinus elevation surgery or implant placement. One month after the extraction, the sinus floor elevation surgery was performed through the extraction socket, and implants were placed 4 months later. An uneventful healing was noted after 6 months of osseointegration; two porcelain-fused-to-metal crowns were fabricated. Clinical follow-up took place every 3 months for 3 years, and successful healing was achieved. The patient was satisfied with the esthetic and functional results of the oral rehabilitation. Sinus floor elevation through an extraction socket without any residual bone, followed by dental implant placement, provided successful functional results and acceptable stability.

To evaluate human corneal endothelial mucin layer thickness and ultrastructure after phacoemulsification and irrigation-aspiration with either next generation ophthalmic irrigating solution (NGOIS) or BSS PLUS. Paired human corneas were mounted in an artificial anterior chamber, exposed to 3 minutes of continuous ultrasound (US) at 80% power using the Alcon SERIES 20000 LEGACY surgical system (n = 9) or to 2 minutes of pulsed US at 50% power, 50% of the time at 20 pps using the Alcon INFINITI Vision System (n = 5), and irrigated with 250 mL of either NGOIS or BSS PLUS. A control group of paired corneas did not undergo phacoemulsification or irrigation-aspiration (n = 5). Corneas were divided and fixed for mucin staining or transmission electron microscopy. Mucin layer thickness was measured on the transmission electron microscopy prints. The mucin layer thickness in the continuous phaco group was 0.77 +/- 0.02 microm (mean +/- SE) with NGOIS and 0.51 +/- 0.01 microm with BSS PLUS (t test, P < 0.001). The mucin layer thickness in the pulsed phaco group was 0.79 +/- 0.02 microm with NGOIS and 0.54 +/- 0.01 microm with BSS PLUS (P < 0.001). The mucin layer thickness in the untreated control group was 0.72 +/- 0.02 microm. The endothelial ultrastructure was normal in all corneas. In this in vitro corneal model, NGOIS, due to its lower surface tension and higher viscosity, preserved endothelial mucin layer thickness better than BSS PLUS with both the INFINITI Vision System (pulsed US) and the LEGACY surgical system (continuous US).

The transjugular intrahepatic portosystemic shunt (TIPS) is widely used for the treatment of portal hypertension in adults, but no studies have defined the best approach to treat portal hypertension in pediatric patients. Pediatric use of TIPS is rare even in large centers of adult practice. The migration of stents has also been reported as a complication in adults. There is no standard way to treat this type of complication, and it is not always clear whether immediate removal or watchful waiting is safer for the patient. We report the case of an 11-year-old patient who underwent urgent TIPS implantation due to variceal bleeding, after unsuccessful sclerotherapy. During the procedure, due to the deep impact of the stent, a second, telescopic, stent was inserted. The portal pressure decreased, no further bleeding occurred, and the patient was listed for transplantation. Three weeks later a routine chest X-ray discovered the migration of the second stent into the right ventricle. No interventional radiological removal or open heart surgery was available for the transplant waiting list patient. The patient underwent uneventful combined liver-kidney transplantation. During the 6-year follow-up period the child had no signs of hemodynamic instability, and his somatic and mental development were appropriate. To our knowledge this case is the first publication on a heart-impacted TIPS stent in a child. The watchful waiting was justified by uneventful combined liver-kidney transplantation and long-term follow-up. This case also underlines the need for best practice guidelines in pediatric portal hypertension.

2005-01-01

Primary hemangiopericytoma of the rib is extremely rare and only a few cases have been reported. A 62-yr-old man presented with an aching chest pain and dyspnea. Thoracic computed tomography revealed a homogenous mass expanding the right seventh rib. A diagnosis of hemangiopericytoma was established by percutaneous needle biopsy. Preoperative embolization of the feeding vessels of the tumor was performed in order to prevent perioperative bleeding. There was no significant bleeding during the surgery, where complete resection of the tumor with 7th to 9th ribs with a surgical margin of 5 cm was performed. Postoperative course was uneventful and there has been no recurrence for thirteen months. To our knowledge, there has been no report to apply a preoperative embolization of a primary hemangiopericytoma of the rib. PMID:15832008

Abstract Atrioventricular groove rupture is a rare, albeit mortal, complication following mitral valve surgery. Avoidance is the best strategy but it cannot fully prevent the occurrence of this complication. Several repair techniques have been described with varying success rates; however, the rarity of the complication precludes consensus about the safest technique. Here we report two cases of posterior atrioventricular groove rupture. Both cases were diagnosed immediately after the cessation of cardiopulmonary bypass. Repair was performed successfully with a technique involving the use of biological glue. The postoperative course was uneventful for both of them. Both cases are well with normally functioning mitral prostheses; one with a follow-up time of 5.5 years and the other 10 months. We believe that the glue provides additional hemostasis and support to the repaired area. PMID:25870633

To report a rare case of cerebrospinal fluid gusher and subsequent seizure immediately after cochlear implant electrode insertion. After the cochlear implant electrode was inserted, brisk flow of 10 mL of cerebrospinal fluid was seen. The electrode was promptly inserted and the leak was additionally sealed with fascia. Seconds later, the patient had a tonic-clonic seizure lasting 30 seconds. Two additional episodes occurred during the case. Her postoperative course was uneventful with no subsequent seizures. The device has been successfully activated. Intervention & Technique: Postoperative imaging showed correct intracochlear placement of the electrode as well as an incidental enlarged vestibular aqueduct. Neurology consultation including electroencephalogram was unremarkable. To our knowledge, this is the first report of a seizure temporally associated with cochlear implant electrode insertion. The significance and possible casual relationship between these two events is discussed.

Aneurysms of the inferior thyroid artery (ITA) are extremely rare and potentially determine severe sequelae. We report a case of true ITA aneurysm in a 45-year-old Caucasian woman treated with endovascular embolization; postoperative course was uneventful and, at 6-month follow-up, the aneurysm is completely thrombized. A systematic review of the literature has been also performed to identify the epidemiologic and clinical characteristics and diagnostic and operative options of this disease. Size alone is not able to predict the fate of the aneurysm and an aggressive treatment seems to be justified because of the high risk of complications in case of rupture. In an emergency setting, the endovascular procedures associated to hematoma evacuation or open surgery should be rapidly performed to save patient life. Copyright © 2016 Elsevier Inc.

2018-01-01

A 29-year-old patient had undergone an elective lower-segment caesarean section (LSCS) five months previously at a district hospital. The operation and the immediate postoperative period were uneventful. After five months she presented back with a fistulous opening. A fistulogram revealed a connection between the uterus and the skin. Fistulous tract excision was planned. Intraoperatively there was communication between the skin and the uterine cavity, with extensive necrosis of the uterine wall. The patient gave her informed consent for excision of the fistulous tract and/or total abdominal hysterectomy. During surgery, it was deemed that there was no scope for excision, so the decision was made for a total abdominal hysterectomy. Histopathological examination confirmed tuberculosis and the patient responded well to anti-tubercular drugs. This case report describes a rare presentation of tubercular uterocutaneous fistula after caesarean section.

To compare torsional versus combined torsional and conventional ultrasound modes in hard cataract surgery regarding ultrasound energy and time and effect on corneal endothelium. Kasr El Aini hospital, Cairo University, and International Eye Hospital, Cairo, Egypt. Ninety-eight eyes of 63 patients were enrolled in this prospective comparative randomized masked clinical study. All eyes had nuclear cataracts of grades III and IV using the Lens Opacities Classification System III (LOCS III). Two groups were included, each having an equal number of eyes (49). The treatment for group A was combined torsional and conventional US mode phacoemulsification, and for group B torsional US mode phacoemulsification only. Pre- and post-operative assessments included best corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp evaluation, and fundoscopic evaluation. Endothelial cell density (ECD) and central corneal thickness (CCT) were measured preoperatively, 1 day, 7 days, and 1 month postoperatively. All eyes were operated on using the Alcon Infiniti System (Alcon, Fort Worth, TX) with the quick chop technique. All eyes were implanted with AcrySof SA60AT (Alcon) intraocular lens (IOL). The main phaco outcome parameters included the mean ultrasound time (UST), the mean cumulative dissipated energy (CDE), and the percent of average torsional amplitude in position 3 (%TUSiP3). Improvement in BCVA was statistically significant in both groups (P < 0.001). Comparing UST and CDE for both groups revealed results favoring the pure torsional group (P = 0.002 and P < 0.001 for UST; P = 0.058 and P = 0.009 for CDE). As for %TUSiP3, readings were higher for the pure torsional group (P = 0.03 and P = 0.01). All changes of CCT, and ECD over time were found statistically significant using one-way ANOVA testing (P < 0.001). Both modes are safe in hard cataract surgery, however the pure torsional mode showed less US energy used.

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.

This paper aims to describe the rare post-operative complication of a lymphocele formation after lateral lumbar interbody fusion. The patient in this case was a 76-year-old lady with a 10 year history of low back pain and neurogenic claudication. She had previously underwent multiple spine surgeries for her condition. She presented to our institution for a recurrence of her low back pain and right anterior thigh pain. She then underwent surgery in two stages; first, a mini-open lateral interbody fusion at L3/4 and L4/5; second, posterior instrumentation of T3 to S1 with sagittal spinal deformity correction. The patient recovered uneventfully in the initial post op period and was discharged within 8 days. However, she developed abdominal distension and discomfort 6 months after surgery. MRI and CT scan of her abdomen showed a retroperitoneal fluid collection compressing her left ureter, resulting in hydroureter and hydronephrosis. She was managed with a CT-guided drainage of the fluid collection. Fluid analysis was consistent with a lymphocele. Since the procedure, the patient has been asymptomatic for 2 years. Delayed lymphocele formation is a potential complication of lateral lumbar interbody fusion. When present, it can be managed conservatively with good results. This case suggests that surgeons should have a low threshold to investigate for a lymphocele development post-anterior or lateral lumbar spine surgery. The authors recommend the placement of a post surgical retroperitoneal drain, as it might assist in the early detection of a lymphocele formation.

Background The operative techniques to close extensive wounds to the duodenum are well described. However, postoperative morbidity is common and includes suture line leak and the formation of fistulae. The aim of this case series is to present pancreas sparing duodenectomy as a safe and viable alternative procedure in the emergency milieu. Methods Five patients underwent emergency pancreas sparing duodenal excisions. Re-implantation of the papilla of Vater or the papilla with a surrounding mucosal patch was performed in two patients. In one, the procedure was further supplemented with a duodenocholangiostomy, stapled pyloric exclusion and enterogastrostomy to defunction the pylorus. In another three patients, distal duodenal excisions were done. Results In four patients, an uneventful recovery was made. One patient died following a myocardial infarction. The surgery lasted meanly 160 minutes with average blood loss of approximately 500 milliliters. The mean hospital stay was 12 days. Enteral nutrition was introduced within the 20 hours after the surgery. Long term follow-up of all surviving patients confirmed a good outcome and normal nutritional status. Conclusion Based on the presented series of patients, we suggest that pancreas-sparing duodenectomy can be considered in selected patients with laceration of the duodenum deemed unsuitable for surgical reconstruction.

Neonatal sigmoid volvulus is a rare entity. It is associated with Hirschsprung's disease. Presentation is acute abdominal distention, vomiting and obstipation. Abdominal radiograph will show the "coffee bean" sign, but this is frequently missed and the diagnosis requires a high index of suspicion. Treatment options include contrast enema, colonoscopy or laparotomy, depending on the condition of the baby and local availability. During the last 6years, 6 infants with sigmoid volvulus were treated in our department. Four presented during the first 48h since birth, and 2 presented at the age of 2 and 7weeks of age. One child was operated and 5 had primary contrast enema with radiologic de-volvulus. Rectal biopsy was performed in all cases; three children had Hirschsprung's disease. Those with normal biopsies responded well to rectal washouts. Two patients had early one stage transanal pullthrough and one had 2 further occasions of sigmoid volvulus prior to definitive surgery. All three recovered with an uneventful course. Neonatal sigmoid volvulus requires a high level of suspicion. Contrast enema is efficient for primary de-volvulus. Rectal biopsy should be performed and if positive for Hirschsprung's disease, surgery should be performed sooner rather than later. Copyright © 2016 Elsevier Inc. All rights reserved.

Female, 45 FINAL DIAGNOSIS: Arterio-venous fistula of the splean Symptoms: Lef-side abdominal pain Medication: - Clinical Procedure: - Specialty: Surgery. Rare disease. Splenic arterial-venous fistula and atrial myxoma are not rare cases but the co-existence of both lesions in the same patient is unpublished so far. A 45- year-old woman presented with vague left flank pain. She was initially scanned by B-dimensional echography, which revealed multiple enlarged hypo-echoic lesions in the splenic hilum. To further characterize the lesion, we performed computed tomography angiography (CTA). CTA showed dilatation of the splenic artery, and aneurismal dilatation of the splenic vein, associated with early opacification of the portal system. CTA showed also an intrasplenic venous aneurism, which was presumed to be the site of fistulous communication. Celiac arteriography confirmed the CTA findings. A left atrial mass was detected by cardiac echography, which was evaluated better by CTA, and was consistent with atrial myxoma. The patient underwent open surgery in different stage with resection of the atrial mass and spleen. The postoperative period was uneventful. This is a unique case in the literature, showing the coexistence of a dual-pathology splenic arterial venous fistula and atrial myxoma.

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.

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.

This syndrome complex includes congenital bicuspid aortic valve, Seller's grade II aortic regurgitation, juxta- subclavian coarctation, stenosis of ostium of left subclavian artery and ruptured sinus of Valsalva aneurysm without any evidence of infective endocarditis. This type of constellation is extremely rare. Neither coarctation of aorta with left subclavian artery stenosis nor the rupture of sinus Valsalva had a favorable pathology for percutaneus intervention. Taking account into morbidity associated with repeated surgery and anesthesia patient underwent a single stage surgical repair of both the defects by two surgical incisions. The approaches include median sternotomy for rupture of sinus of Valsalva and lateral thoracotomy for coarctation with left subclavian artery stenosis. The surgery was uneventful. After three months follow up echocardiography showed mild residual gradient across the repaired coarctation segment, mild aortic regurgitation and no residual left to right shunt. This patient is under follow up. This is an extremely rare case of single stage successful repair of coarctation and rupture of sinus of Valsalva associated with congenital bicuspid aortic valve.

Colorectal cancer (CRC) is the most common form of cancer and the third leading cause of death in Taiwan. Serum alpha-fetoprotein (AFP) has been extensively used as a biomarker for hepatocellular carcinoma (HCC) and yolk sac tumors. This case report presents a 90-year-old woman with right abdominal pain and poor appetite for 1 week. The computed tomography (CT) showed wall thickening in the proximal ascending colon with ruptured appendicitis. Preoperative serum AFP was high. There was no definite liver metastasis or other abnormal findings in the hepatobiliary systems. After initial empirical antibiotic treatment, we performed laparoscopic right hemicolectomy. The pathological assessment was poorly differentiated adenocarcinoma with neuroendocrine differentiation in the ascending colon. The tumor cells did not produce AFP. Amazingly, the follow-up serum AFP level 1 month after the surgery declined to normal range. The patient had an uneventful course after the surgery and was free of recurrence or metastasis within 5 months of follow-up. AFP may be a useful tumor marker in poorly differentiated colorectal cancer with neuroendocrine component patients and a prediction of early treatment response.

Unconventional Management of Chyloascites After Laparoscopic Nissen Fundoplication

Ospina, Karen A.; Lee, Earl H.; Rehring, Scott R.

2012-01-01

Background & Objectives: Chyloascites is a rare complication that can result from abdominal trauma, neoplasm, inflammatory conditions, or various abdominal surgeries. Few cases have been described secondary to iatrogenic injury from laparoscopic Nissen fundoplication. We describe a case in which this surgery resulted in chyloascites that was successfully treated by lymphatic glue embolization. Methods: A 37-year-old male presented with signs and symptoms consistent with chronic reflux disease. He underwent an uneventful laparoscopic Nissen fundoplication. Two weeks postoperatively, he was admitted for dehydration. During his admission, he began to develop a persistent cough, shortness of breath, and abdominal distention. Imaging and fluid analysis from thoracocentesis and paracentesis were consistent with chyle leakage. Despite nonoperative measures, the patient's presentation persisted. Results: Thoracic duct ligation was performed without success. Bipedal lymphangiography identified an extensive leak revealing a severely lacerated thoracic duct spilling contrast freely into the abdomen and no contrast entering the thoracic duct in the chest. The site of injury was successfully sealed off with percutaneous glue embolization through lymph channels. Conclusion: Chyloascites is a rare complication of laparoscopic Nissen fundoplication. When not successful with conservative measures, lymphatic glue embolization can provide effective treatment. PMID:23477184

Single-site laparoscopic surgery and natural orifice transumbilical surgery (NOTUS) have become exciting areas of surgical development. However, most reported case series consist of basic laparoscopic procedures, such as cholecystectomy and appendectomy. In this paper, we present the case of an advanced laparoscopic operation-construction of a gastrointestinal anastomosis-that was performed through ports placed entirely within the umbilicus. In this paper, we describe a 61-year-old male with a history of advanced pancreatic carcinoma who was referred with a gastric outlet obstruction. A laparoscopic gastrojejunostomy bypass, using a linear stapler with suture closure of the enterotomy, was performed through three abdominal trocars placed entirely within the umbilicus. Some potential advantages of NOTUS palliative gastrojejunostomy include reduced postoperative pain and the lack of visible abdominal scars. The operation was completed uneventfully in 40 minutes. The patient recovered without complications and was discharged on postoperative day 2. At 1-month follow-up, the patient had improved oral intake without any further vomiting symptoms. This case report documents the feasibility of an advanced anastomotic gastrojejunostomy procedure which can be performed through a single site. However, benefits of this approach, compared to conventional laparoscopic procedures, will require a prospective randomized clinical trial.

Soft tissue grafting to improve implant esthetics

PubMed Central

Kassab, Moawia M

2010-01-01

Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and allografting to correct a buccal dehiscence around tooth #24 after a malpositioned implant placed by a different surgeon. A 25-year-old woman presented with the chief complaint of gingival recession and exposure of implant threads around tooth #24. The patient received three soft tissue grafting procedures to augment the gingival tissue. The first surgery included a connective tissue graft to increase the width of the keratinized gingival tissue. The second surgery included the use of autografting (connective tissue graft) to coronally position the soft tissue and achieve implant coverage. The third and final surgery included the use of allografting material Alloderm to increase and mask the implant from showing through the gingiva. Healing period was uneventful for the patient. After three surgical procedures, it appears that soft tissue grafting has increased the width and height of the gingiva surrounding the implant. The accomplished thickness of gingival tissue appeared to mask the showing of implant threads through the gingival tissue and allowed for achieving the desired esthetic that the patient desired. The aim of the study is to present a clinical case with soft tissue grafting procedures. PMID:23662087

We present a case of 12-month-old boy with congenitally corrected transposition of great arteries with L-looped ventricles and L-transposition of great arteries and ventricular septal defect. When admitted to the hospital, the patient had the appearance of congestive heart failure due to moderate to severe tricuspid valve regurgitation and right ventricle dysfunction. The pulmonary artery (PA) banding was required first because of low systolic pressure in the morphological left ventricle less than 70% confirmed by catheterization. Three months later, the patient appeared to be a good candidate for anatomical repair and a double switch procedure-Senning with arterial switch-was performed. The early postoperative period was relatively smooth and uneventful. Tricuspid valve insufficiency was resolved immediately after surgery. Mild systolic dysfunction of the left ventricle with mild mitral insufficiency was confirmed by the 2D strain method of echocardiography on the second day of the postoperative period and it improved over the next 21 days. Thirty days later after the procedure, the patient underwent catheterization of his superior vena cava tunnel because of the slightly increased blood flow velocity diagnosed by echocardiography. In 3 months after the surgery, the boy was asymptomatic and was doing well. The patient's functional status was I according to the NYHA classification. © The Author 2016.

Zhang, Shikun; Ma, Ying; Ma, Tie; Wang, Zhiming

2017-01-01

Abstract Rationale: Low-grade myofibroblastic sarcoma (LGMS) is a malignant lesion composed of myofibroblasts. It is an uncommon tumor of unknown etiology that mainly develops in the bone or soft tissue and is most often reported in the head and neck, particularly in the tongue and oral cavity. Patient concerns: A 2-year-old girl, previously well and with no significant medical history or family history of other diseases, presented with a 2-week painless swelling of the right orbit. Diagnoses: Preoperative computed tomography (CT) revealed a large homogeneous enhanced mass, 21 × 13 mm in size, located on lateral wall of the right orbit with bone absorption. The mass was resected and histopathological examination revealed LGMS of the orbit. Interventions: On May 2016, she underwent surgery without the additional postoperative treatment. Outcomes: The patient's postoperative course was uneventful, and was discharged on the 6th day after surgery. During a year follow-up period, there was no recurrence of the postoperative CT. The patient and her family were satisfied with the result of the surgery. Lessons: Based on clinical characteristics and postoperative CT, we considered the mass may be a benign tumor. We completely resected along the capsule without an extensive surgical margin. However, postoperative histopathology diagnose LGMS, which shows a strong potential for local recurrence and vascular invasion. So we should close observation of the patient's symptoms and sign. If the tumor has invaded adjacent tissues, we will use adjuvant chemotherapy or radiotherapy. PMID:29390454

To determine the intraoperative and early postoperative complications of manual sutureless cataract extraction. Case series. Redo Eye Hospital, Rawalpindi, Pakistan, from January 2009 to December 2010. Three hundred patients of cataract through purposive non-probability sampling were selected. The patients underwent manual sutureless cataract surgery (MSCS) by single experienced surgeon and intraoperative complications were documented. The surgical technique was modified to deal with any intraoperative complications accordingly. Patients were examined on the first postoperative day and on the first postoperative week for any postoperative complications. The data was entered in Statistical Package for Social Sciences (SPSS) version 13.0 and the results were calculated in frequencies. Among the 300 cases, 81.3% surgeries went uneventful whereas 18.6% had some complication. The common intraoperative complications were superior button-hole formation in 5%; posterior capsular rent in 5% and premature entry with iris prolapse in 3% cases. Postoperatively, the commonly encountered complications were striate keratopathy in 9.6% and hyphema 9%. At first week follow-up, 4% had striate keratopathy and 0.6% had hyphema. Striate keratopathy resolved with topical medication on subsequent follow-up. A total of 9 cases (3%) underwent second surgery: 2 cases for lens matter wash, 2 cases for hyphema and 5 cases needed suturing of wound for shallow anterior chamber due to wound leak. Superior button-hole formation, posterior capsular rent and premature entry were the common intraoperative complications of MSCS whereas the common early postoperative complications were striate keratopathy and hyphema.

Chasioti, Evdokia; Chiang, Tat Fai; Drew, Howard J

2013-01-01

Prosthetic guided implant surgery requires adequate ridge dimensions for proper implant placement. Various surgical procedures can be used to augment deficient alveolar ridges. Studies have examined new bone formation on deficient ridges, utilizing numerous surgical techniques and biomaterials. The goal is to develop time efficient techniques, which have low morbidity. A crucial factor for successful bone grafting procedures is space maintenance. The article discusses space maintenance tenting screws, used in conjunction with bone allografts and resorbable barrier membranes, to ensure uneventful guided bone regeneration (GBR) enabling optimal implant positioning. The technique utilized has been described in the literature to treat severely resorbed alveolar ridges and additionally can be considered in restoring the vertical and horizontal component of deficient extraction sites. Three cases are presented to illustrate the utilization and effectiveness of tenting screw technology in the treatment of atrophic extraction sockets and for deficient ridges.

Intraoperative detection of methemoglobinemia in a patient given benzocaine spray to relieve discomfort from a nasogastric tube: a case report.

Young, Barb

2008-04-01

A 27-year-old man who had 2 admissions 1 month apart for abdominal surgery had a high methemoglobin (MHb) level secondary to liberal use of benzocaine oral spray. A co-oximetry level for MHb of greater than 0.30 proportion of total hemoglobin (30.1%) was detected intraoperatively. The patient was successfully treated with methylene blue intravenously and recovered uneventfully. When the arterial blood gas with a normal partial pressure of oxygen is inconsistent with a low pulse oximeter reading and with the physical appearance of the patient, methemoglobinemia should be considered as a differential diagnosis. This case illustrates the acquired form of methemoglobinemia. Adequate oxygen delivery to the tissues in the body is compromised when MHb overwhelms the capacity of the red blood cells to carry oxygen. If methemoglobinemia is left untreated, it may be fatal.

A 59-year-old man was admitted to hospital for investigation of a 1-year history of intermittent hematuria. He had undergone ileal ureteral replacement for left renal stones 36 years earlier. Renal ultrasonography, physical examination, abdominal plain radiography, intravenous urography, CT urography, measurement of serum levels of creatinine, urea and electrolytes, renal scintigraphy, urinalysis and urine culture. Staghorn calculi in the left kidney, with a high-lying anastomosis between the renal pelvis and the proximal ileal segment. The patient underwent percutaneous nephrolithotomy via a middle-calyx access for the large staghorn stones. After surgery, no residual calculi were found and the patient was discharged with an uneventful postoperative course. At 1 month, renal scintigraphy showed normal bilateral kidney function. The patient received potassium citrate supplementation and was followed up with 6-monthly imaging studies. At the last report, he had been stone-free for 7 months.

We present a case of nephrotic syndrome associated with right atrial and supra hepatic vein part of inferior vena caval thrombosis. This patient presented with dyspena, lower extremity edema and back pain after a vehicle accident and blunt trauma to the abdomen. Trauma should be considered not only as a thrombophilic pre-disposition, but also as a predisposing factor to IVC endothelium injury and thrombosis formation. Echocardiography revealed supra hepatic vein IVC thrombosis floating to the right atrium. A C-T scan with contrast also showed pulmonary artery emboli to the left upper lobe. With open heart surgery, the right atrial and IVC clot were extracted and the main left and right pulmonary arteries were evaluated for possible clot lodging. The patient had an uneventful postoperative recovery and thrombosis has not reoccurred with periodical follow-up examinations. © 2016 KUMS, All rights reserved.

Yan, Zhongshu; Liao, Guoqing

2005-01-01

Background Rectovaginal fistula is uncommon after lower anterior resection for rectal cancer. The most leading cause of this complication is involvement of the posterior wall of the vagina into the staple line when firing the circular stapler. Case presentation A 50-year-old women underwent resection for obstructed carcinoma of the sigmoid colon with Hartmann procedure. Four months later she underwent restorative surgery with circular stapler. Following which she developed rectovaginal fistula. A transvaginal repair was performed but stool passing from vagina not per rectum. Laporotomy revealed colovaginal anastomosis, which was corrected accordingly. Patient had an uneventful recovery. Conclusion Inadvertent formation of colovaginal anastomosis associated with a rectovaginal fistula is a rare complication caused by the operator's error. The present case again highlights the importance of ensuring that the posterior wall of vagina is away from the staple line. PMID:16285887

Large, long standing goiters present multiple challenges to anaesthesiologist. Post thyroidectomy haematoma is a rare but life threatening complication of thyroid surgery leading to airway obstruction. We report a case of huge goiter that underwent near total thyroidectomy and developed post thyroidectomy haematoma. Within no time it resulted in near fatal airway obstruction, pulmonary oedema and cardiac arrest. The haematoma was evacuated immediately and patient was resuscitated successfully. Pulmonary oedema was further worsened by subsequent aggressive fluid resuscitation. She was electively ventilated with PEEP and was extubated after five days. Except for right vocal cord palsy her postoperative stay was uneventful. This is unique case where a post thyoidectomy haematoma has resulted in fatal supraglottic oedema and pulmonary oedema. Early recognition, immediate intubation and evacuation of haematoma are the key to manage this complication. We highlight on the pathophysiology of haematoma and discuss the strategies to prevent similar events in future.

A 77-year-old man presented with exertional dyspnea. He had undergone aortic and mitral valve replacement with tissue valves 6-years earlier. The patient's hemoglobin level was 9.8 g/dl and serum aspartate aminotransferase (70 mU/ml) and lactate dehydrogenase (1,112 mU/ml) were elevated. Echocardiography revealed stenosis of the prosthetic valve in the aortic position with peak flow velocity of 3.8 m/second and massive mitral regurgitation. The patient underwent repeat valve replacement. Pannus formation around both implanted valves was observed. The aortic valve orifice was narrowed by the pannus, and one cusp of the prosthesis in the mitral position was fixed and caused the regurgitation, but they were free from cusp laceration or calcification. The patient's postoperative course was uneventful, and he continues to do well 14 months after surgery.

The Vibrant Soundbridge is a semi-implantable middle ear hearing device used in the rehabilitation of adults with sensorineural hearing loss. In order to evaluate the long-term effects of the implanted part of the device, audiological data from 39 patients implanted over several implant sites across France were collected and analyzed retrospectively. The mean follow-up time was 16 months; 25 patients had a follow-up period of over 1 year. Surgery was uneventful in all cases. The present study of the 39 implanted patients with a mid- to long-term follow-up found a statistically significant modification of hearing thresholds (pre- versus postoperative) for frequencies of 0.5 and 4 kHz. However, the shift of threshold was rather limited (2.79 and 3.34 dB, respectively), and this variation was not statistically different from the evolution of the opposite non-operated ear.

A primary hepatic neuroendocrine tumour (PHNET) is a very rare disease. The liver represents the preferential site for neuroendocrine tumors' metastases. A 45-year old Caucasian female who presented with nausea, vomiting, diarrhea, accompanied by diffuse abdominal pain was found to have on contrast-enhanced computer tomography an encapsulated, partially cystic liver mass. The patient underwent an uneventful left atypical hepatic resection. Histopatological and immunohistochemical examination revealed a slowly growing (G1) hepatic neuroendocrine tumour. Post surgery, the specific neuroendocrine markers (serum Chromogranin A and 24h urinary 5 hydroxy-indolacetic acid) were within normal range. Further functional imaging investigations were performed. No other lesions were found making probable the diagnosis of PHNET. The patient is presently after 4 years of follow-up with no local recurrence or distant metastases. The diagnosis of PHNET is a medical challenge that requires a thorough long term follow-up in order to exclude an occult primary neuroendocrine tumour.

We report a successful result of treatment for a ruptured thoracoabdominal aortic aneurysm with aortitis syndrome. A 43-year-old male suffered sudden low back pain, that was diagnosed as a ruptured thoracoabdominal aortic aneurysm based on abdominal computed tomography. Preoperative angiography revealed a thoracoabdominal aortic aneurysm with occlusion of the superior mesenteric artery, and well developed Riolan's archade. The aneurysm was replaced by a prosthetic graft with partial femoro-femoral bypass in conjunction with selective cold perfusion for the visceral arteries. Total extracorporeal circulation time, and aortic clamptime, was 187 minutes and 132 minutes, respectively. The postoperative courses of liver and renal function were excellent. The patient recovered from surgery uneventfully. It was suggested that selective cold visceral perfusion was effective for prevention of renal and liver dysfunction associated with a ruptured thoracoabdominal aneurysm.

We report a case of fish bone penetration of the duodenum extending into the pancreatic head, which was successfully treated by surgery. A 73-year-old woman was admitted with upper abdominal dull pain that had persisted for 3 days. Computed tomography showed a linear calcified body, which appeared to penetrate the posterior wall of the duodenal bulb into the pancreatic head. A laparotomy was performed based on the preoperative diagnosis of localized peritonitis caused by penetration of the duodenum into the pancreas by an ingested foreign body. The foreign body was safely removed from both the pancreas and duodenum and was found to be a fish bone, measuring 4 cm in length. Neither an abscess nor hematoma was detected at the site of the pancreatic head. The postoperative course was uneventful. This case demonstrates an unusual presentation of fish bone penetration of the duodenum with a migration to the pancreas.

Objective To report a single-incision laparoscopic cholecystectomy (SILC) for a patient with cholecystitis that required endoscopic nasogallbladder drainage (ENGBD). Clinical Presentation and Intervention A 75-year-old man was diagnosed with moderate acute cholecystitis and underwent antiplatelet therapy for a history of brain infarction. An ENGBD was performed as an initial treatment for his cholecystitis. After recovery from the cholecystitis, a SILC was performed using a SILS Port with an additional forceps. Because neither Rouviere's sulcus nor Calot's triangle could be identified with a favorable laparoscopic view, the fundus-first procedure was selected. The patient's postoperative course was uneventful, and he was discharged from the hospital on day 3 after surgery. Conclusion In this case of a patient who had cholecystitis that required ENGBD, a SILC was successful performed using a combination of SILS Port with additional forceps and fundus-first procedure.

State-of-the-art treatment for Chiari Malformation I (CM-I) consists of decompression by posterior fossa craniectomy. A rare but severe complication that develops over months to years after this procedure is cerebellar slump. Treatment options for this condition are limited. We present a new and promising approach to treat this rare condition. The patients were placed in the Trendelenburg position to facilitate ascent of the cerebellum. After almost complete dissolution of neurologic symptoms, surgical reconstruction was performed by tonsillar resection and the creation of a new structural support using a bone graft. Both patients experienced good clinical and morphological outcomes immediately after surgery, and for two years thereafter. Neurological symptoms related to cerebellar or brainstem slump can be adequately reversed by placing the patient in the Trendelenburg position. After uneventful gravitational reversal of the slump, safe surgical reconstruction of the cerebellar support can be performed to securely preserve the anatomical reversal.

Monotonous work has been analyzed from sociological and social psychological perspectives in terms of consequences for job satisfaction, life satisfaction, leisure activities, and health. In this article, a distinction is made between repetitive and uneventful monotony. Psychobiological reactions to these tasks are analyzed and related to possible long-term consequences for health. Strategies for work reform required for the two types of monotony are discussed.

Lissajous figures: an engineering tool for root cause analysis of individual cases--a preliminary concept.

Some patients have short intensive care stay periods and little or no organ dysfunction after cardiac surgery and others do not despite seemingly faultless surgery, perfusion, and anesthesia. These "unknown" reasons for death and morbidity usually relate to organ ischemia and inflammation, but are obviously mutlifactorial. A Lissajous figure is a technique in electrical engineering to compare two different electrical signals. We utilize this basic concept in a very simple manner to potentially identify why some of these unknown deaths or morbidities occur. Utilizing an electronic perfusion database, we retrospectively analyzed 43 patients undergoing aortic surgery with regard to central venous saturations during cooling and rewarming. Isolated aortic valve replacement patients were excluded. Central venous saturation, time, and temperature were plotted to create a Lissajous figure for the whole operation, and during cooling and rewarming separately. Temperature and saturations were analyzed every 20 seconds. Perfusion related variables were registered and uploaded to www.perfsort.net. Lissajous figures during cooling add little to patient care due to their similarity. Isolated rewarming revealed startling differences. It is immediately visually obvious who had short and long periods of tissue ischemia and reperfusion during rewarming in a seemingly uneventful operation. The periods of ischemia can be semi quantified into: none, mild, moderate, and severe. Creation of simple Lissajous figures during rewarming for bypass runs may be an additional helpful tool in root cause analysis of patient death/morbidity when surgery, perfusion, and anesthesia seemed faultless. Low central venous saturations at hypothermic temperatures mean significant metabolic activity, indicating tissue ischemia is occurring. Further work is needed to correlate this concept to outcomes.

Tuberculous aortic pseudoaneurysm associated with vertebral tuberculosis is a rare disease but with very high mortality. We review the literature and find 19 reports with 22 patients. Here we report three cases with vertebral tuberculosis, who also have tuberculous pseudoaneurysm of the aorta. These patients were treated by different methods. We try to analyze the epidemiology, pathogenesis, presentation, and management of this disease to find the best treatment. The patients presented with different symptoms such as pain (chest, abdominal or back), fever, blood volume reduction or hemorrhagic shock symptoms. Large mass also could be observed by imaging. In addition to clinical manifestations, enhanced computed tomography or magnetic resonance imaging could also help the diagnosis of this disease. Tuberculous aortic pseudoaneurysm associated with vertebral tuberculosis. Three patients were treated with anti-tuberculosis(TB) drugs or combined with different sequences surgical treatment: Case 1 refused to receive pseudoaneurysm surgery and only had anti-TB drug treatment; Case 2 received thoracic spinal surgery first; Case 3 received endovascular stent grafting. Two patients (case 1 and case 2) who refused to undergo aneurysm surgery died. The last patient (case 3) underwent endovascular repair and antibiotic therapy for tuberculosis, and the postoperative course was uneventful; the patient recovered and survived. Once the diagnosis of tuberculous pseudoaneurysm is confirmed, surgical treatment should be provided immediately combined with anti-tuberculosis drugs. The aim of the treatment is to save lives, prevent relapse, and facilitate the return to normal life, regardless of the size of the pseudoaneurysm. The pseudoaneurysm should be treated first to prevent aneurysm rupture before the vertebral tuberculosis surgery.

To determine patient independency, health-related and disease-specific quality of life (QOL), gait pattern, and muscle strength in patients after salvage arthroplasty for failed internal fixation of a femoral neck fracture. Secondary cohort study to a randomized controlled trial. Multicenter trial in the Netherlands, including 14 academic and nonacademic hospitals. Patients after salvage arthroplasty for failed internal fixation of a femoral neck fracture were studied. A comparison was made with patients who healed uneventfully after internal fixation. None (observatory study). Patient characteristics, SF-12, and Western Ontario McMaster osteoarthritis index scores were collected. Gait parameters were measured using plantar pressure measurement. Maximum isometric forces of the hip muscles were measured using a handheld dynamometer. Differences between the fractured and contralateral leg were calculated. Groups were compared using univariate analysis. Of 248 internal fixation patients (median age, 72 years), salvage arthroplasty was performed in 68 patients (27%). Salvage arthroplasty patients had a significantly lower Western Ontario McMaster osteoarthritis index score (median, 73 vs. 90; P = 0.016) than patients who healed uneventfully after internal fixation. Health-related QOL (SF-12) and patient independency did not differ significantly between the groups. Gait analysis showed a significantly impaired progression of the center of pressure in the salvage surgery patients (median ratio, -8.9 vs. 0.4, P = 0.013) and a significant greater loss of abduction strength (median, -25.4 vs. -20.4 N, P = 0.025). Despite a similar level of dependency and QOL, salvage arthroplasty patients have inferior functional outcome than patients who heal after internal fixation of a femoral neck fracture.

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.

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.

Myofibrosarcoma treated with Mohs micrographic surgery.

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 from other somewhat less aggressive malignancies such as dermatofibrosarcoma protuberans or malignant fibrous histiocytoma. Specific histopathologic criteria are reviewed. We recommend including Mohs micrographic surgery in the armamentarium for the treatment of this rare tumor.

Abstract Clinically significant sellar cysts unrelated to pituitary adenomas are uncommon. Intracranial cholesteatomas are also rare and are most common in the middle ear and mastoid region. We report an even rarer case of cholesteatoma in the sellar region—a challenging diagnosis guided by clinical presentations, radiological signs, and biopsy, aiming at emphasize the importance of considering cholesteatoma when making differential diagnoses of sellar lesions. We present a case of cholesteatoma in the sellar region in a 56-year-old man with hypopituitarism, diabetes insipidus, and cystic imaging findings. It was difficult to make an accurate diagnosis before surgery. We present detailed analysis of the patient's disease course and review pertinent literature. The patient underwent a surgical exploration and tumor resection through a transsphenoidal approach. Pathologic results revealed a cholesteatoma. The patient's symptoms improved a lot after surgery, and the postoperative period was uneventful. Taken together, the lesion's imaging appearance, pathological characteristics, and clinical features were all unique features that lead to a diagnosis of cholesteatoma. As we did not see such reports by Pubmed and EMBASE, we believe this is the first reported case of sellar cholesteatoma presenting in this manner. This article emphasized that cholesteatomas, although rare, should be considered part of the differential diagnosis of sellar lesions. PMID:26962793

To evaluate the upper airway characteristics in the early postoperative period after maxilomandibular advancement for obstructive sleep apnea syndrome. Nasopharyngolaryngoscopy was performed before and 48 hours after surgery on 70 consecutive patients who underwent maxillomandibular advancement for obstructive sleep apnea syndrome. The preoperative and the postoperative evaluations were performed by the same examiner for consistency. Mild to moderate lateral pharyngeal wall edema was identified in 70 consecutive patients. Fourteen patients (20%) had edema as well as ecchymosis involving the pyriform sinus and aryepiglottic fold. Four of these patients (6%) were also noted to have hypopharyngeal hematoma involving the pyriform sinus, aryepiglottic fold, arytenoid, and false vocal cord that partially obstructed the airway. These four patients were closely monitored for 1 to 2 additional days for possible expanding hematoma leading to airway compromise. None of these patients were found to have airway difficulty, and the minimum oxygen saturation was more than 90% throughout the hospitalization. All four patients were discharged uneventfully, and the hematoma resolved completely within 10 days. Although postoperative edema was expected after maxillomandibular advancement, hypopharyngeal hematoma was unexpected. Although none of our patients had evidence of airway difficulty, the possibility of an expanding hypopharyngeal hematoma should be considered in patients complaining of breathing difficulty after maxillomandibular advancement surgery.

Some intracranial procedures are achievable with patients awake, however, there are challenges ranging from patient compliance to homeostasis. The aim of this study is to present a case of intracranial surgery for removal of a tumor in the left parietal lobe with the patient awake during the procedure. After patient selection and psychological preparation, the proposed excision of the left parietal lobe lesion in the waking state was clarified and accepted. Continuous infusion of propofol and remifentanil was administered to maintain a Ramsay score of 2-3. The bilateral scalp blockade was performed with ropivacaine. The Mayfield head fixation device was installed and drapes adjusted to maintain the airway and eyes accessible for mapping with electrical stimulation and tumor excision. For dura mater incision, a pad with 2% lidocaine was applied for 3 minutes. The surgery was uneventful. The patient was discharged on the seventh day of hospitalization without presenting complication. Although the maintenance of analgesia and hemodynamic stability was a challenge with the patient awake, the target-controlled infusion of propofol provided the desired level of consciousness, remifentanil titrated analgesia and sedation without drug accumulation, and the blockade with ropivacaine provided satisfactory analgesia. We conclude that the anesthetic technique was satisfactory for our patient. Copyright © 2013 Sociedade Brasileira de Anestesiologia. Published by Elsevier Editora Ltda. All rights reserved.

Chromosome 4p- syndrome is a multiple malformation syndrome associated with partial deletion of the short arm of chromosome 4 (4p-). It is characterized by dysmorphic features and retarded development. Cleft lip and/or palate are the major clinical manifestations. Cases of tetrasomy 9p are extremely rare; the principal clinical manifestations of this condition are characteristic craniofacial abnormalities, generalized hypotonia and severe mental retardation. We present the first case of a female infant with 4p deletion and tetrasomy 9p mosaicism, exhibiting a left-sided cleft lip, alveolus and soft palate. Karyotype analysis of lymphocytes cultured from the patient revealed that she was mosaic: 86% of the cells were 46, XX, add (4) (p15.32) and 14% were 47, XX, add (4) (p15.32), +idic (9)(q12). The G-banding pattern appeared consistent with either translocation or partial proximal deletion of 4p. In order to make a definitive cytogenetic diagnosis of isodicentric chromosome 9, fluorescence in situ hybridization (FISH) was applied. At 8 months, when the patient weighed 4.3 kg, her cleft lip was repaired. Before and after surgery there were no seizures, and the postoperative course was uneventful.

Solitary glandular papilloma of the peripheral lung: a report of two cases

PubMed Central

2014-01-01

Solitary papilloma of the lung is thought to be a rare benign epithelial tumor, and complete surgical resection is currently the standard treatment for this pathology. However, some cases of papilloma have reportedly shown malignant potential. We report two cases of solitary glandular papilloma of the peripheral lung that were treated by thoracoscopic partial resection. The first patient presented with a nodular lesion in the lower lobe of the left lung that was detected on a follow-up chest computed tomography (CT) scan after treatment for laryngeal cancer. Partial lung resection was performed by video-assisted thoracoscopic surgery. In the second patient, a nodular lesion was incidentally identified in the lower lobe of the left lung during a health check-up. Partial lung resection was again performed by video-assisted thoracoscopic surgery. The postoperative course in both cases was uneventful, and no recurrences have been observed as of 44 months and 41 months postoperatively, respectively. To the best of our knowledge, malignant transformation has been reported both with the squamous type and the mixed type of solitary papilloma of the lung. The glandular variant has shown no tendency toward local recurrence after local excision and has no apparent malignant potential. Local excision is thus recommended for solitary glandular papilloma in order to preserve pulmonary function. PMID:24885310

The glandular variant has shown no tendency toward local recurrence after local excision and has no apparent malignant potential. Local excision is thus recommended for solitary glandular papilloma in order to preserve pulmonary function.

The management of eyes with nanophthalmos is a dilemma for ophthalmologists due to various complications, especial the eye with malignant glaucoma. We report a case of effective treatment for malignant glaucoma in nanophthalmos. An 82-year-old man was performed phacoemulsification in the right eye with normal ocular pressure and nanophthalmos. The surgery was uneventful: an intraocular lens (IOL) was placed and centered in the capsular bag. 2 months later, the patient presented with malignant glaucoma, and the intraocular pressure fluctuated between 18.6 mmHg and 30.8 mmHg with antiglaucoma medications. The patient did not respond to surgical peripheral iridotomy and goniosynechialysis. Then a single treatment with laser peripheral lens posterior capsulotomy and vitreous anterior membranectomy was performed. The intraocular pressure normalized, and the anterior chamber deepened within 24 h. The patient's condition remained stable for 9 months with no further treatment, and his Snellen corrected distance visual acuity was 20/50. The left eye of this patient was treated by combined surgery including phacoemulsification, IOL implantation, anterior vitrectomy, surgical peripheral iridotomy (PI), and goniosynechialysis. No intraoperative or postoperative complications were observed. This case suggests that it is essential to choose a suitable treatment for nanophthalmos patients to deal with malignant glaucoma and to reduce the incidence of malignant glaucoma.

Anthropometric variations in humans make it difficult to replace a temporomandibular joint (TMJ), successfully using a standard “one-size-fits-all” prosthesis. The case report presents a unique concept of total TMJ replacement with customized and modified TMJ prosthesis, which is cost-effective and provides the best fit for the patient. The process involved in designing and modifications over the existing prosthesis are also described. A 12-year- old female who presented for treatment of left unilateral TMJ ankylosis underwent the surgery for total TMJ replacement. A three-dimensional computed tomography (CT) scan suggested features of bony ankylosis of left TMJ. CT images were converted to a sterolithographic model using CAD software and a rapid prototyping machine. A process of rapid manufacturing was then used to manufacture the customized prosthesis. Postoperative recovery was uneventful, with an improvement in mouth opening of 3.5 cm and painless jaw movements. Three years postsurgery, the patient is pain-free, has a mouth opening of about 4.0 cm and enjoys a normal diet. The postoperative radiographs concur with the excellent clinical results. The use of CAD/CAM technique to design the custom-made prosthesis, using orthopaedically proven structural materials, significantly improves the predictability and success rates of TMJ replacement surgery.

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.

Purpose To compare the intraoperative performances and postoperative outcomes of cataract surgery performed with longitudinal phacoemulsification and torsional phacoemulsification in moderate and hard cataracts. Methods Of 85 patients who had senile cataracts, 102 eyes were operated on using the Infiniti Vision System. Preoperative examinations (slit lamp examination, mean central corneal thickness, and central endothelial cell counts) were performed for each patient. Cataracts were subdivided into moderate and hard, according to the Lens Opacities Classification System III grading of nucleus opalescence (NO). Eyes in each cataract group were randomly assigned to conventional and torsional phaco-mode. Intraoperative parameters, including ultrasound time (UST), cumulative dissipated energy (CDE), and the balanced salt solution plus (BSSP) volume utilized were evaluated. Best corrected visual acuity (BCVA) was checked on postoperative day 30; mean central corneal thickness and central endothelial cell counts were investigated on postoperative days 7 and 30. Results Preoperative BCVA and mean grading of NO showed no difference in both groups. Preoperative endothelial cell count and central corneal thickness also showed no significant difference in both groups. In the moderate cataract group, the CDE, UST, and BSSP volume were significantly lower in the torsional mode than the longitudinal mode, but they did not show any difference in the hard cataract group. Torsional group showed less endothelial cell loss and central corneal thickening at postoperative day seven in moderate cataracts but showed no significant differences, as compared with the longitudinal group, by postoperative day 30. Conclusions Torsional phacoemulsification showed superior efficiency for moderate cataracts, as compared with longitudinal phacoemulsification, in the early postoperative stage. PMID:21165231

Maltepe University School of Medicine Department of Ophthalmology, Istanbul, Turkey. Comparative case series. Eyes were assigned to 2.2 mm microcoaxial phacoemulsification using the torsional mode with a 22-degree bent tip (Group 1) or a 12-degree bent tip (Group 2). The primary outcome measures were ultrasound time (UST), cumulative dissipated energy (CDE), longitudinal and torsional ultrasound (US) amplitudes, mean surgical time, mean volume of balanced salt solution used, and surgical complications. Both groups included 45 eyes. The mean UST, CDE, longitudinal US amplitude, and torsional US amplitude were 65 seconds ± 27.23 (SD), 11.53 ± 6.99, 0.22 ± 0.26, and 42.86 ± 15.64, respectively, in Group 1 and 84 ± 45.04 seconds, 16.68 ± 10.66, 0.48 ± 0.68, and 46.27 ± 14.74, respectively, in Group 2. The mean UST, CDE, and longitudinal amplitudes were significantly lower in Group 1 (P=.003, P=.008, and P=.022, respectively). The mean volume of balanced salt solution was 73.33 ± 28.58 cc in Group 1 and 82.08 ± 26.21 cc in Group 2 (P=.134). Torsional phacoemulsification performed with 22-degree bent tips provided more effective lens removal than 12-degree bent tips, with a lower UST and CDE. Copyright © 2013 ASCRS and ESCRS.

To compare the safety and efficacy of microcoaxial phacoemulsification surgeries performed with the Ozil Intelligent Phaco (IP) torsional mode and combined torsional/longitudinal ultrasound (US) mode using the Infiniti Vision System (Alcon Laboratories). In this prospective randomized comparative study, 60 eyes were assigned to 2.2-mm microcoaxial phacoemulsification using the Ozil IP torsional mode (group 1) or combined torsional/longitudinal US mode (group 2). The primary outcome measures were US time (UST), cumulative dissipated energy (CDE), longitudinal and torsional ultrasound amplitudes, mean operation time, mean volume of balanced salt solution (BSS) used, and surgical complications. Both groups included 30 eyes. Mean UST, CDE, and longitudinal and torsional ultrasound amplitudes in group 1 were 1 minute 15±34.33 seconds, 8.74±5.64, 0.43±0.74, and 25.56±8.56, respectively, and these parameters in group 2 were 1 minute 40±51.44 seconds, 9.28±5.99, 3.64±1.55, and 3.71±1.34, respectively. UST and longitudinal amplitudes were found to be significantly low in group 1 (p<0.001, p<0.001), whereas torsional amplitude was found to be significantly high in this group (p=0.001). Mean volumes of BSS used in groups 1 and 2 were 63.30±18.00 cc and 84.50±28.65 cc, respectively (p=0.001). The Ozil IP torsional mode may provide more effective lens removal than the combined torsional/longitudinal US mode with a lower UST and volume of BSS used.

Laparoscopic Heller cardiomyotomy and Dor fundoplication is the surgical procedure of choice for esophageal achalasia. The aim of our study was to investigate the clinical outcome and safety of laparoscopic Heller-Dor procedure performed by using Hook electrocautery and as a teaching module for advanced laparoscopic surgery. Between January 2005 and December 2010, 25 consecutive patients with achalasia underwent laparoscopic Heller-Dor operation by a single surgeon. All the patients received upper gastrointestinal series (barium swallow), esophagogastroscopy, and esophageal manometry to exclude esophageal carcinoma and to confirm the diagnosis. All the patients were operated by laparoscopic modified Heller myotomy with Dor fundoplication by using hook electrocautery. Among 25 operated patients, 14 were male and 11 were female with a median age of 43 years (range 18-72 years). The mean operative time was 93.3 min (range 50-50 min), the mean operative blood loss was 90 ml (range 40-200 ml), the median time to oral feeding was 2 days (2-4 days), and the median hospital stay was 4 days (4-7 days). There was no conversion to open surgery. Intraoperative mucosal perforation was encountered in three patients and was repaired in all of them by laparoscopic suture. All the patients had an uneventful recovery without postoperative complication and had excellent clinical response (96 %) during follow-up. Laparoscopic Heller-Dor operation using hook electrocautery is safe, inexpensive, and effective treatment for achalasia which is useful for teaching and training surgical residents in advanced laparoscopic surgery.

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.

Syringomyelia following surgery for a spontaneous spinal subdural hematoma in a 13-year-old girl with congenital von Willebrand disease: case report and literature review.

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.

Ventral transpalpebral anterior orbitotomy: surgical description and report of 3 cases.

To describe a surgical approach to allow access to the ventral anterior canine orbit and report outcomes of three cases. After induction of general anesthesia and aseptic preparation of the surgical site, a 2.5- to 3-cm curvilinear skin incision was created through the inferior eyelid at the level of the ventral orbital rim. A combination of sharp and blunt dissection facilitated entrance into the ventral anterior orbital space for the removal of diseased tissues or allows for drainage of purulent debris. Two-layer closure was performed, and postoperative lateral temporary tarsorrhaphy sutures were retained to provide globe protection. Three dogs underwent unilateral ventral transpalpebral anterior orbitotomy. Prior to surgery, apart from a complete ophthalmic examination, ocular ultrasound was used to diagnose orbital disease in two cases, and MRI was utilized in the third case. Exploratory orbitotomy revealed a large mucocele in case 1, orbital bacterial abscessation in case 2, and necrotizing zygomatic sialoadenitis in case 3. Clinical exophthalmos resolved immediately after surgery. The surgical site in all cases healed within 2 weeks. One patient had a superficial corneal ulceration 2 weeks after surgery which healed uneventfully. Recurrence of orbital disease was not noted in any case. Ventral transpalpebral anterior orbitotomy is a simple procedure that allows easy access to the ventral anterior orbit to allow for removal of diseased tissues or to facilitate drainage of abscessation. Recurrence of orbital disease was not seen in any patient, with one patient experiencing blindness as a long-term complication following the procedure. © 2015 American College of Veterinary Ophthalmologists.

Diagnostic transgastric flexible peritoneoscopy: is pure natural orifice transluminal endoscopic surgery a fantasy?

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.

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 be safely performed in an outpatient clinic, in the absence of the anesthesia service and with limited workup and monitoring. Basic first aid and basic life support skills seem to be sufficient in case of an adverse event. An MET provides a generous failsafe for this low-risk procedure.

A 53-year-old man presented with a 6-month history of intermittent right flank pain. Radiological imaging confirmed the diagnosis of retrocaval ureter (RCU) and ureteral calculus. Retroperitoneal laparoendoscopic single-site surgery (LESS) ureterolithotomy and ureteroureterostomy was successfully performed. The operative time was 185 min and the blood loss was approximately 20 ml. The patient's postoperative course was uneventful. Postoperative analgesia was not needed. The patient was discharged on the third postoperative day. The drain and double-J stent were respectively removed at 1 and 8 weeks postoperatively. At the 3-month follow-up, nuclear scan showed no evidence of obstruction of the right kidney and the patient also remained symptom free. It may be concluded that retroperitoneal LESS repair for RCU is a feasible and safe procedure, which can be considered as a option for the management of RCU even if it is complicated by the presence of a ureteral calculus.

Management of presacral hemorrhage is always challenging. Herein we describe the use of an absorbable hemostatic gauze with α-cyanoacrylate medical adhesive to achieve hemostasis. In this study, we conducted total mesorectal excision for the treatment of rectal cancer in 258 patients from March 2006 to May 2009. Intraoperative presacral hemorrhage developed in 5 (2%) patients during rectal mobilization. In these 5 patients, massive bleeding could not be controlled by pressure and pelvic packing with gauze. An absorbable hemostatic gauze spread with medical adhesive was compressed onto the bleeding vessel for at least 20 minutes. Hemostasis was achieved successfully and was maintained during the surgery. Patients recovered uneventfully and no postoperative events were noted. The use of an absorbable hemostatic gauze with medical adhesive is a simple and effective method for achieving hemostasis when massive presacral hemorrhage occurs. However, its effectiveness needs to be confirmed in a controlled study in a properly selected patient population. Copyright © 2012. Published by Elsevier Inc.

Reports on perianal atypical leiomyoma, a perianal tumor, are rare. We confirmed a perianal atypical leiomyoma by its clinical presentation, magnetic resonance imaging findings, and immunohistochemistry. A 28-year-old female with a perianal mass found more than 4 years ago. The 5cm_4cm_4cm sized mass was located on the left side of the anus and vagina; The magnetic resonance imaging (MRI) scan revealed: A 4.1cm × 5.2cm × 4.9cm sized round mass was observed on the left side of the circumference. Perianal atypical leiomyoma. anal peripheral mass resection was performed under lumbar anesthesia. The postoperative course was uneventful, healing, the patient was discharged. Perianal atypical leiomyomas are benign tumors, but with the clinically atypical leiomyoma, it is sometimes difficult to distinguish between potential malignant smooth muscle tumors,and there may be malignant changes. Surgery should ensure complete resection, and to avoid postoperative recurrence, there should be a regular follow-up.

Lenticular subluxation in a patient with homocystinuria undetected by neonatal screening.

2007-12-01

A case of homocystinuria with lenticular subluxation was misdiagnosed as Marfan syndrome since the patient had no apparent mental impairment and had had a negative neonatal screen for homocystinuria. The delayed diagnosis of homocystinuria was due to a negative prior neonatal screen which was checked when he was a breastfed healthy newborn. In the absence of an autosomal dominant family history, and because of prior poor school performance, amino acid analysis and mutational analysis of the cystathionine beta-synthase gene were performed, which revealed the presence of homocystinuria. Low methionine diet with vitamin B6, folic acid, betaine, dipyridamole and aspirin was prescribed for emergency ophthalmologic surgery to prevent thromboembolic events. Fortunately, the operation was completed uneventfully. The patient has been followed-up for 4 years without any significant complaints under diet and medical control. Since homocystinuria is easily missed in neonatal screening programs, it should be suspected in patients who present with lenticular subluxation, even after a negative neonatal screen.

Recurrent Pneumonia due to Fibrosing Mediastinitis in a Teenage Girl: A Case Report with Long-Term Follow-Up

Springer, Chaim; Wasser, Oren; Avital, Avraham; Koplewitz, Benjamin Z.

2018-01-01

A teenage girl was evaluated for recurrent right pneumonia. The evaluation revealed a calcified mediastinal mass that compressed the right intermediate and middle lobar bronchi, as well as the right pulmonary artery and veins. The clinical picture together with imaging studies and borderline positive serology testing suggested a diagnosis of fibrosing mediastinitis associated with histoplasmosis. This rare condition is characterized by the local proliferation of invasive fibrous tissue within the mediastinum due to a hyperimmune reaction to Histoplasma capsulatum. Antifungal and anti-inflammatory therapies are usually ineffective, and surgical intervention contains a high morbidity risk. Palliative surgery and stenting of the compressed airway have been suggested. In the past, the prognosis was thought to be poor, but recent studies demonstrate a more positive outcome. Our patient had been radiologically and functionally stable under follow-up for over thirteen years and has married and delivered two healthy children, both following an uneventful pregnancy.

Hall, Brittany A; Ketz-Riley, Cornelia J

2011-07-01

A 3-year-old female spayed domestic ferret (Mustela putorius furo) was presented for evaluation of severely increased liver enzyme activities noted prior to anesthesia. The ferret showed no clinical signs of liver or gall bladder disease. Serum biochemical profile confirmed elevations in alanine aminotransferase and alkaline phosphatase activity and total bilirubin concentration. Abdominal ultrasound revealed a distended and convoluted common bile duct although no obstruction was seen. Upon exploratory laparotomy, a large amount of sediment was found within the bile duct that appeared to be obstructing it, but no other cause for the obstruction was found. A choledochoduodenostomy was performed, and the ferret recovered uneventfully from surgery. Liver enzyme activities returned to normal by 5 days post-operatively. Biopsy and culture results yielded no definitive cause of the bile duct obstruction. Cholestasis is a rarely reported disease in ferrets and generally has been described in connection with neoplasia or parasitism, neither of which was found in the current case.

Transcatheter aortic valve implantation (TAVI) was introduced as an alternative treatment for patients with severe symptomatic aortic stenosis for whom surgery would be high-risk. Prosthetic aortic valve endocarditis is a serious complication of surgical AVR (SAVR) with high morbidity and mortality. According to recent cases, post-TAVI prosthetic valve endocarditis (PVE) seems to occur very rarely. We present the case of a 75-year-old woman who underwent TAVI (Edwards Saphien XT) with an uneventful postoperative stay. She was diagnosed with endocarditis using three dimensional (3D) echocardiography on the TAVI device 7 months later and she subsequently underwent surgical aortic valve replacement. Little experience of the interpretation of transoesophageal echocardiography (TEE) and the clinical course and effectiveness of treatment strategies in post-TAVI endocarditis exists. We report a case of PVE in a TAVI patient which was diagnosed with three-dimensional transoesophageal echocardiography (3DTEE). Copyright © 2016 Hellenic Cardiological Society.

Percutaneous endoscopic colostomy (PEC) is increasingly proposed as an alternative to surgery to treat various disorders, including acute colonic pseudo-obstruction, chronic intestinal pseudo-obstruction and relapsing sigmoid volvulus. We report on a severe complication that occurred two months after PEC placement. A 74-year-old man with a history of chronic intestinal pseudo-obstruction evolving since 8 years was readmitted to our hospital and received PEC to provide long-standing relief. The procedure was uneventful and greatly improved the patient’s quality of life. Two months later, the patient developed acute stercoral peritonitis. At laparotomy, the colostomy flange was embedded in the abdominal wall but no pressure necrosis was found at the level of the colonic wall. This complication was likely related to inadvertent traction of the colostomy tube. Subtotal colectomy with terminal ileostomy was performed. We review the major features of 60 cases of PEC reported to date, including indications and complications. PMID:17465514

2014-01-01

A case of acute sigmoid volvulus in a 14-year-old adolescent girl presenting with acute low large bowel obstruction with a background of chronic constipation has been presented. Abdominal radiograph and CT scan helped in diagnosis. She underwent emergency colonoscopic detorsion and decompression uneventfully. Lower gastrointestinal contrast study showed very redundant sigmoid colonic loop without any transition zone and she subsequently underwent elective sigmoid colectomy with good outcome. The sigmoid volvulus should be considered in the differential diagnosis of paediatric acute abdomen presenting with marked abdominal distention, absolute constipation and pain but without vomiting. Plain abdominal radiograph and the CT scan are helpful to confirm the diagnosis. Early colonoscopic detorsion and decompression allows direct visualisation of the vascular compromise, assessment of band width of the volvulus and can reduce complications and mortality. Associated Hirschsprung's disease should be suspected if clinical and radiological features are suggestive in which case a rectal biopsy before definitive surgery should be considered. PMID:25143313

Mechanical small bowel obstruction following a blunt abdominal trauma: A case report

PubMed Central

Zirak-Schmidt, Samira; El-Hussuna, Alaa

2015-01-01

Introduction Intestinal obstruction following abdominal trauma has previously been described. However, in most reported cases pathological finding was intestinal stenosis. Presentation of the case A 51-year-old male was admitted after a motor vehicle accident. Initial focused abdominal sonogram for trauma and enhanced computerized tomography were normal, however there was a fracture of the tibia. Three days later, he complained of abdominal pain, constipation, and vomiting. An exploratory laparotomy showed bleeding from the omentum and mechanical small bowel obstruction due to a fibrous band. Discussion The patient had prior abdominal surgery, but clinical and radiological findings indicate that the impact of the motor vehicle accident initiated his condition either by causing rotation of a bowel segment around the fibrous band, or by formation of a fibrous band secondary to minimal bleeding from the omentum. Conclusion High index of suspicion of intestinal obstruction is mandatory in trauma patients presenting with complaints of abdominal pain, vomiting, and constipation despite uneventful CT scan.

Lap-Protector, which is an abdominal wall sealing device, is usually used for wound protection from implantation of malignant cells or pyogenic fluid. A circular stapler is a common easy-to-use device for anastomosis of the digestive tract. We report the case of an infected pancreatic pseudocyst which was treated by surgical procedure using these useful devices. A 69-year-old man was followed up in our hospital after severe acute pancreatitis. He had undergone drainage surgeries twice for intractable pancreatic abscess followed by severe acute pancreatitis. He was admitted to our hospital complaining of loss of appetite, hiccups, and high fever. Computed tomography of the abdomen revealed an infected pancreatic pseudocyst which compressed the gastric wall. Internal drainage into the stomach was performed using Lap-Protector and circular stapler. The patient recovered uneventfully. Recently many endoscopic or laparoscopic procedures in cystogastrostomy are reported; however, a conventional open surgical approach is also important. This easy method may be useful for operative cystogastrostomy. PMID:20805947

A Rare Case of De Novo Gigantic Ovarian Abscess within an Endometrioma

2010-01-01

We are reporting a rare case of de novo ovarian abscess in an endometrioma. Ovarian abscess within an endometrioma is a rare gynecological problem, but de novo abscess in the endometrioma is even rarer. Most of the ovarian abscesses develop in the endometriomas following interventions, e.g., aspiration, pelvic surgery, and oocyte retrieval. We are presenting a case of a spontaneous giant abscess in a large ovarian cyst in a nulliparous woman who presented with acute abdomen. Patient was treated in a district general hospital with multidisciplinary approach. Thirteen liters of the pus were drained. She has had a sub total (supra cervical) hysterectomy and bilateral salpingo-oophorectomy (BSO) performed. Histology of the abscess wall confirmed endometriotic nature of the cyst. Patient made an uneventful recovery and was discharged home on the 14th postoperative day. This case highlights that endometrioma and its complication can present as a surgical emergency and should be dealt as one. PMID:20589187

Antibacterial effect and proposed mechanism of action of a topical surgical adhesive.

2018-01-01

Medical adhesives effectively hold closed approximated skin edges of wounds from surgical incisions, including punctures from minimally invasive surgery. In addition, they have been reported to be antibacterial against gram-positive bacteria. Using membrane filtration to capture all organisms after contact with 2-octyl cyanoacrylate product for 3 minutes, we quantified the number of survivors. Controls were performed to rule out that the noted level of kill was caused by carryover product in the test system. We found that the product kills >7 logs of gram-positive and gram-negative bacteria. The mechanism of action for the antibacterial effect is described as a function of very low water content. As an antibacterial agent, the risk of nosocomial infection is greatly diminished, and an uneventful clinical result is facilitated. Bacterial growth cannot occur in the formulation and on contact death rapidly ensues as cellular water diffuses from the cell into the product.

Kidney tumours are often found incidentally in the work-up of abdominal pain. We are reporting, to the best of our knowledge, the first series of robot-assisted radical nephrectomy (RARN) combined with cholecystectomy (RACH) in patients with organ-confined right kidney tumour and gallbladder stones. A solid organ-confined tumour of the right kidney, along with gallbladder stones, was demonstrated on CT in three patients following evaluation of colic-like abdominal pain. The tumours were deemed unsuitable for nephron-sparing surgery. A combined RARN with RACH in a single session was proposed for all the patients. Mean console time was 187 min. Estimated blood loss was minimal and all three patients had an uneventful recovery. The pathology reports confirmed complete excision of renal cell carcinoma with negative surgical margins and the gallbladders showed no signs of malignancy. Concomitant RARN-RACH for tumour in the right kidney and gallstones is a safe and effective procedure with excellent oncological and functional results. Copyright © 2014 John Wiley & Sons, Ltd.

We report here the case of a patient with anterior segment migration of intravitreal dexamethasone implant as well as its management and outcome. The patient had the following sequence of events: complicated cataract surgery, iris-sutured intraocular lens implant, followed by cystoid macular edema treated with intravitreal Avastin, retinal vein occlusion treated with intravitreal dexamethasone implant, corneal decompensation treated with Descemet stripping automated endothelial keratoplasty (DSAEK), and finally recurrence of macular edema treated with repeated intravitreal dexamethasone implant. Dexamethasone implant had completely dissolved from the eye 12 weeks after insertion without any complication. A conservative approach with regular monitoring in the situation of a quiet anterior segment without any corneal decompensation can provide enough time for the implant to dissolve without causing any complication to the involved eye, avoiding any additional surgical intervention, as presented in this case report. Despite the fact that the implant was left for natural dissolution, there were no adverse effects related to the graft or the eye.

A 81-year-old male was referred to our emergency outpatient unit due to acute renal failure. The level of serum creatinine was 276 μmol/l. A CT scan showed bilateral hydronephroureter, large bladder stone (7 cm × 6 cm × 6 cm) and bladder wall thickness. He was diagnosed as post renal failure due to bilateral hydronephroureter. Large bladder stone is thought to be the cause of bilateral hydronephroureter and renal failure. To improve renal failure, we performed open cystolithotomy and urethral catheterization. Three days after the surgery, the level of serum creatinine decreased to 224 μmol/l. He was discharged from our hospital with uneventful course. Bladder calculus is thought to be a rare cause of renal failure. We summarize the characteristics of bladder calculus causing renal failure. We should keep that long-term pyuria and urinary symptom, and repeated urinary tract infection can cause huge bladder calculus and renal failure in mind.

Becker muscular dystrophy (BMD) is a progressive neuromuscular disorder caused by mutations in the dystrophin gene. The sensitivity to non-depolarizing muscle relaxant in a patient with muscle dystrophy is reportedly higher than that in normal individuals, and the duration of the effect is known to be prolonged. In this report, we present the case of a 58-year-old man with BMD who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis under total intravenous anesthesia without the use of muscle-relaxant drugs and supplemented with regional anesthesia. Anesthesia was induced and maintained with propofol, remifentanil, and fentanyl; ultrasound-guided bilateral rectus sheath block (RSB) and right-sided subcostal transversus abdominis plane block (TAP) were performed. The procedure required conversion to open surgery because of hard conglutination; intraoperative and postoperative periods were uneventful. Adequate analgesia was maintained after extubation because of the effect of RSB and TAP.

Use of the Uro Dyna-CT in endourology – the new frontier

ABSTRACT We describe the use of the Uro Dyna-CT, an imaging system used in the operating room that produces real-time three-dimensional (3D) imaging and cross-sectional image reconstructions similar to an intraoperative computerized tomography, during a percutaneous nephrolithotomy and a contralateral flexible ureteroscopy in a complete supine position. A 65 year-old female patient had an incomplete calyceal staghorn stone in the right kidney and a 10mm in the left one. The procedure was uneventful and the intraoperative use of the Uro Dyna-CT identified 2 residual stones that were not found by digital fluoroscopy and flexible nephroscopy at the end of surgery, helping us to render the patient stone-free in one procedure, which was confirmed by a postoperative CT scan. Prospective studies will define the real role of the Uro Dyna-CT for endourological procedures, but its use seems to be a very promising tool for improving stone free rates and decreasing auxiliary procedures, especially for complex cases.

Trapped lung is defined by the lung's inability to expand and fill the thoracic cavity because of a restricting "peel" caused by benign or malignant pleural disease. However, trapped lung secondary to pneumothorax is rarely reported. We present a case of trapped lung caused by a pneumothorax that occurred some 14 years before the patient presented to our hospital with a complaint of incapacitating dyspnea. Computed tomography (CT) scans revealed trapping of the right lung with abnormal thickening of the visceral pleura. In view of the patient's history of pneumothorax, we concluded that his dyspnea was attributable mainly to the trapping of his lung by the earlier pneumothorax. We therefore scheduled thoracoscopic decortication, which was successfully completed. The patient's recovery after the operation was uneventful, and seven weeks after surgery the right lung had re-expanded well. © 2018 The Authors.

Swallowed foreign bodies in adults.

Foreign-body ingestion is a common event most often seen in children from 6 months to 6 years of age. In adults, foreign bodies are usually ingested accidentally together with food. This happens more commonly in persons with certain pathological changes of the gastrointestinal tract. We present a selective review of pertinent literature retrieved by a search in the PubMed database. The foreign bodies most commonly ingested by adults are fish bones and chicken bones. The clinical approach to the problem depends on the type of material ingested and on the patient's symptoms and physical findings. In about 80% of cases, the ingested material passes uneventfully through the gastrointestinal tract; endoscopy is performed in about 20% of cases, and surgery in less than 1%. Emergency esophagogastroduodenoscopy (EGD) is recommended when the esophagus is completely occluded (because of the risk of aspiration and/or pressure necrosis), when the ingested object has a sharp point or edge (because of the risk of perforation, with ensuing mediastinitis or peritonitis), and when a battery has been ingested (because of the risk of necrosis and fistula formation). For non-occluding esophageal foreign bodies, including magnets, an urgent but non-emergency EGD within 12 to 24 hours is recommended. Most patients can be treated conservatively by observation alone, but there should be a low threshold for deciding to proceed to endoscopic retrieval. Surgery is reserved for complicated cases.

Mucocele of the appendix is a rare clinicopathological entity simulating acute appendicitis. The most common form of the mucocele is cystadenoma, which is characterized by luminal dilatation producing large amounts of mucin. We present a new case of a giant mucocele of appendix with mucinous cystadenoma. A 61-year-old female was admitted with complaints of severe lower right quadrant pain. Ultrasonography and computed tomography (CT) suggested that it was a mucocele, but due to severity of pain, she underwent an emergency operation. Fortunately, without a perforation, it was a giant mucocele and the operation was terminated with an uneventful appendectomy with segmental cecal resection. The histopathological evaluation of the specimen reported to be a mucocele with mucinous cystadenoma with negative surgical margins. The patient was discharged postoperative 6th day, and a control colonoscopy and abdominal CT was planned for 6 months following surgery. Appendicular mucocele is rare and difficult to diagnose preoperatively, and sometimes it may be of large size which increases the risk of perforation. Pseudomyxoma peritonei (PP) is the most feared complication of mucocele perforation. Appendectomy with negative margins is a requirement for adequate treatment for most cases. Utmost care should be taken during surgery to avoid perforation of mucocele. Sertkaya M, Emre A, Pircanoglu EM, Peker O, Cengiz E, Karaagaç M. Giant Appendicular Mucocele Due to Mucinous Cystadenoma.

Cerebral coenurosis is a disease of the central nervous system in sheep and goats, and is usually fatal unless surgical relief is provided. Information regarding neuroanaesthesia in veterinary medicine in goats is scant. We describe anaesthetic management of an intact female goat (2 years; 16 kg) presented for craniectomy. The goat was sedated with xylazine (0.05 mg kg -1 , i.m.) and morphine (0.05 mg kg -1 , i.m.). General anaesthesia was induced 20 min later with propofol and maintained with a constant rate infusion of propofol (0.2 mg kg -1  min -1 ). A cuffed endotracheal tube was placed and connected to a rebreathing (circle) system and mechanical ventilation with 100% oxygen was initiated. A bolus of lidocaine (1 mg kg -1 ), midazolam (0.25 mg kg -1 ) and fentanyl 2.5 μg kg -1 was delivered via the intravenous route followed immediately by a constant rate infusion of lidocaine (50 μg kg -1  min -1 ), midazolam (0.15 mg kg -1  h -1 ) and fentanyl (6 μg kg -1  h -1 ) administered via the intravenous route throughout surgery. Craniectomy was undertaken and the goat recovered uneventfully. Total intravenous anaesthesia with propofol, lidocaine, fentanyl and midazolam could be an acceptable option for anaesthesia during intracranial surgery in goats.

Right hemicolectomy for mesenteric phlebosclerosis potentially caused by long-term use of herbal medicine: A case report and literature review.

Mesenteric phlebosclerosis is a rare ischemic disease affecting the colon. Systemic disease and herbal medicine have been pointed out as possible causes, and the disease is characterized by calcifications involved the mesocolic veins. Patients who do not respond to conservative therapy require surgical treatment. In surgical intervention, an adequate extent of colonic resection is important. We present a case of an 87-year-old woman with mesenteric phlebosclerosis who had consumed herbal medicine for 40 years. She suffered from ileus caused by mesenteric phlebosclerosis, and the symptoms did not improve with conservative therapy. Right hemicolectomy was performed since the disease was localized in the right colon. Long-term use of herbal medicine was considered the potential cause of mesenteric phlebosclerosis. The postoperative course was mostly uneventful. The patient stopped using herbal medicine and had no signs of recurrence 2 years after surgery. The greatest concern in surgery for mesenteric phleboscrerosis is to detect the affected area, which should be removed. Characteristic findings in computed tomography and intraoperative findings can help to determine the optimal extent of colonic resection. Mesenteric phlebosclerosis caused by herbal medicines occurs as localized disease in the right colon compared with mesenteric phlebosclerosis caused by other pathogenesis. Limited colonic resection is usually indicated for mesenteric phlebosclerosis caused by herbal medicine. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

CADASIL (cerebral arteriopathy, autosomal dominant, with subcortical infarcts and leu-koencephalopathy) is an infrequent inherited disease that could have anesthetic implica-tions. However these have rarely been reported. We present a male patient previously diagnosed with CADASIL, who had suffered an ischemic vascular cerebral accident with a MRI compatible with leukoencephalopathy, and who was dependent for daily activities, and sustained dementia, mood alterations, apathy, and urine incontinence. He had famil-ial antecedents of psychiatric symptoms and ischemic stroke events in several relatives including his father, two brothers and one sister. He was scheduled for arthrodesis of the left knee because of multiple infectious complications of prosthetic knee surgery. He was under clopidogrel treatment which was withdrawn seven days before surgery. The pro-cedure was performed under combined spinal-epidural anesthesia, intraoperative seda-tion with midazolam, and postoperative multimodal analgesia including epidural patient controlled analgesia. The perioperative management was uneventful and we outline the adequacy of managing these patients under regional anesthesia and analgesia, as these permit to maintain hemodynamic stability leading to adequate cerebral perfusion, key to avoid an increase in the effects of the chronic arteriopathy patients with CADASIL sustain.

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.

Laparoscopic endoloop technique - A novel approach of managing iatrogenic caecal perforation and literature review.

An iatrogenic caecal perforation is rare, but a serious complication associated with significant morbidity and mortality. We present a 4min and 50s video on a new improvisation undertaken during laparoscopic management of post-polypectomy caecal perforation. Our patient presented with an acute abdomen following endoscopic polypectomy. At surgery, the site of caecal perforation was close to the appendicular base with devitalization tissue, secondary to diathermy usage. The hallmark of safety within this novel technique included fresh healthy tissue margins within the endoloop (detachable snare ligation) and ensuring no ischemic tissue was gathered. Complete freeing of the appendix and meso-appendicular base was required and securing three endoloops proximal to the site of perforation. The post-operative course was uneventful. The World Society of Emergency Surgery (WSES) 2013 guidelines suggested an early laparoscopic approach is a safe and effective treatment for colonoscopy-related colonic perforation. There are no national guidelines and the management is dictated by the clinical condition of the patient, co-morbidity, size and site of perforation as well as the scale of bowel preparation, and surgical experience. The endoloop technique described, undertaken during a laparoscopy is a novel approach. It is a simple and effective method, reminding clinicians to adapt techniques when necessary. Nevertheless, it is only limited to perforations around the appendicular base. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

The aim of this study is to describe a total endovascular aortic repair with branched and fenestrated endografts in a young patient with Marfan syndrome and a chronic aortic dissection. Open surgery is the gold standard to treat aortic dissections in patients with aortic disease and Marfan syndrome. In 2000, a 38-year-old man with Marfan syndrome underwent open ascending aorta repair for an acute type A aortic dissection. One year later, a redo sternotomy was performed for aortic valve replacement. In 2013, the patient presented with endocarditis and pulmonary infection, which necessitated tracheostomy and temporary dialysis. In 2014, the first stage of the endovascular repair was performed using an inner branched endograft to exclude a 77-mm distal arch and descending thoracic aortic aneurysm. In 2015, a 63-mm thoracoabdominal aortic aneurysm was excluded by implantation of a 4-fenestrated endograft. Follow-up after both endovascular repairs was uneventful. Total aortic endovascular repair was successfully performed to treat a patient with arch and thoraco-abdominal aortic aneurysm associated with chronic aortic dissection and Marfan syndrome. The postoperative images confirmed patency of the endograft and its branches, and complete exclusion of the aortic false lumen.

A 41-year-old woman presented with a large painful and tender mass of the left side of her neck located just below the angle of the mandible. She was also complaining of frequent attacks of symptoms ranging from dizziness upon resuming the erect position to frank syncope. Color-coded duplex showed a large well-vascularized vascular mass at the level of the carotid bifurcation, suggesting the diagnosis of a carotid body tumor (CBT). A computerized tomographic angiography confirmed the diagnosis of a CBT, which measured 5.7 cm in its craniocaudal axis. The tumor appeared to encase the internal carotid artery (ICA) at the level of its origin, indicating the presence of a Shamblin group 3 tumor. During surgery, the CBT seemingly encased the ICA; however, it was successfully taken off the ICA, by establishing an adventitial dissection place, obviating the need for arterial resection and replacement. A brief intraoperative episode of cardiac arrest was successfully managed. Postoperative course was uneventful, and all symptoms were cured. Pathology confirmed the clinical diagnosis and did not show malignancy. In conclusion, meticulous surgical techniques can spare the ICA from removal or inadvertent injury during CBT surgery and reduce the morbidity often associated with the resection of large or advanced tumors but also cure atypical patient symptoms.

Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml -1 mixed with 0.5 ml of fentanyl 50 μg ml -1 . Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery. The patient was reviewed 2 days postoperatively in ward. The thoracic spinal anesthetia was performed easily in the patient. Some discomfort which was readily treated with 1mg midazolam and 20 mg ketamine intravenously. There was no neurological deficit and hemodynamic parameters were in normal range intra and post-operatively and recovery was uneventful. We used a narrow gauze (26G) spinal needle which minimized the trauma to the patient and the chances of PDPH, which was more if 16 or 18G epidural needle had been used and could have increased further if there have been accidental dura puncture. Also using spinal anesthesia was economical although it should be done cautiously as we are giving spinal anesthesia above the level of termination of spinal cord.

Inguinal hernia repairs are routinely performed as outpatient procedures in most patients, whereas a few require admission due to clinical or social peculiarities. Muscular dystrophies are inherited disorders characterized by progressive muscle wasting and weakness. In case of surgery there is no definite recommendation for either general or regional anesthesia. This contribution regards a 48 y. o. male patient diagnosed with Becker Muscular Dystrophy by muscle biopsy 10 years earlier. He had a left-sided sizable inguinoscrotal hernia with repeat episodes of incarceration. An elective mesh repair with suction drainage was accomplished under selective spinal anesthesia. The post-operative course was uneventful. A few inguinal hernia repairs require admission due to peculiarities such as extensive scrotal hernias requiring suction drainage. Muscular dystrophies are inherited disorders with no cure and no two dystrophy patients are exactly alike, therefore the health issues will be different for each individual. In case of surgery there is no definite recommendation for either general or regional anesthesia. This contribution regards the successful elective mesh repair with suction drainage of a large left-sided inguino-scrotal hernia in a 48 y. o. male patient affected by Becker muscular dystrophy by selective spinal anesthesia obtained by 10 milligrams of hyperbaric bupivacaine. Effective mesh repair with suction drainage of large inguinal hernias under spinal anesthesia can be achieved in patients affected by muscular dystrophy.

The objective of this study is to systematically evaluate the effects of a tissue-engineered bone complex for maxillary sinus augmentation in a canine model. Twelve sinus floor augmentation surgeries in 6 animals were performed bilaterally and randomly repaired with the following 3 groups of grafts: group A consisted of tissue-engineered osteoblasts/beta-TCP complex (n=4); group B consisted of beta-TCP alone (n=4); group C consisted of autogenous bone obtained from iliac crest as a positive control (n=4). All dogs had uneventful healings following the surgery. Sequential polychrome fluorescent labeling, maxillofacial CT, microhardness tests, as well as histological and histomorphometric analyses indicated that the tissue-engineered osteoblasts/beta-TCP complex dramatically promoted bone formation and mineralization and maximally maintained the height and volume of elevated maxillary sinus. By comparison, both control groups of beta-TCP or autologous iliac bone showed considerable resorption and replacement by fibrous or fatty tissue. We thus conclude that beta-TCP alone could barely maintain the height and volume of the elevated sinus floor, and that the transplantation of autogenous osteoblasts on beta-TCP could promote earlier bone formation and mineralization, maximally maintain height, volume and increase the compressive strength of augmented maxillary sinus. This tissue engineered bone complex might be a better alternative to autologous bone for the clinical edentulous maxillary sinus augmentation. Copyright (c) 2009 Elsevier Inc. All rights reserved.

The objective of this study was to analyze the surgical results of the simultaneous treatment of femoral pseudoarthrosis and knee stiffness using a combined one-stage approach (quadricepsplasty + osteoperiosteal decortications + bone autografting + fracture stabilization). Twelve patients (six men) followed up for a minimum of 10 years and who had undergone surgery for these combined procedures were contacted for evaluation. Their mean age at the time of the surgery was 30 years (standard deviation, SD 15; range 22-65 years), and mean time from initial trauma was 16 months (SD 6, range 10-32 months). Mean range of motion improved from 10 degrees (SD 9) to 112 degrees (SD 13) postoperatively. Fractures healed in all patients, and improvement in their range of motion was statistically significant (Student's t-test = 31; P

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 should be performed immediately in conjunction with valve replacement even in the acute phase after onset of AMI.

Small bowel obstruction (SBO) is common in adult surgical procedures, mainly due to postoperative adhesions. Acute SBO in adults without history of abdominal surgery, trauma or clinical hernia is less common and has various etiologies. Congenital band is an extremely rare cause. A 56-year-old man was admitted to our hospital with a two-day history of abdominal pain and bilious vomiting. He had no history of abdominal surgery or any other medical problems. A contrast-enhanced CT of the abdomen showed a distention of small bowel loops with transition point in the right hypochondrium. Distended loops of small bowel were located in the left side of the abdomen, whereas collapsed loops was located in the right side. The normal bowel wall enhancement was preserved. After initial treatment with intravenous fluid and nasogastric suction, he was operated. At laparoscopy a band obstructing the ileum was clearly observed. This anomalous band extending from gallbladder to transverse mesocolon caused a small window leading to internal herniation of the small bowel and obstruction. The band was coagulated and divided. Postoperative outcome was uneventful and the patient was discharged on the second postoperative day. There was no recurrence of symptoms on subsequent follow-up. Congenital peritoneal bands are not frequently encountered in surgical practice and these bands are often difficult to classify and define. Diagnosis of acute intestinal obstruction due to CPB must be included in the differential diagnosis in any patient with no history of abdominal surgery, trauma, clinical hernia, inflammatory bowel disease or peritoneal tuberculosis. Despite technological advances in radiology preoperative diagnosis remains difficult, however the diagnosis of SBO due to CPB must be considered in any patient with no history of abdominal surgery, Trauma or clinical hernia consulting for occlusive syndrome. The laparoscopic approach should be intended initially for its feasibility and benefits. Copyright © 2016. Published by Elsevier Ltd.

Comparison of Methodologies Using Estimated or Measured Values of Total Corneal Astigmatism for Toric Intraocular Lens Power Calculation.

Ferreira, Tiago B; Ribeiro, Paulo; Ribeiro, Filomena J; O'Neill, João G

2017-12-01

To compare the prediction error in the calculation of toric intraocular lenses (IOLs) associated with methods that estimate the power of the posterior corneal surface (ie, Barrett toric calculator and Abulafia-Koch formula) with that of methods that consider real measures obtained using Scheimpflug imaging: a software that uses vectorial calculation (Panacea toric calculator: http://www.panaceaiolandtoriccalculator.com) and a ray tracing software (PhacoOptics, Aarhus Nord, Denmark). In 107 eyes of 107 patients undergoing cataract surgery with toric IOL implantation (Acrysof IQ Toric; Alcon Laboratories, Inc., Fort Worth, TX), predicted residual astigmatism by each calculation method was compared with manifest refractive astigmatism. Prediction error in residual astigmatism was calculated using vector analysis. All calculation methods resulted in overcorrection of with-the-rule astigmatism and undercorrection of against-the-rule astigmatism. Both estimation methods resulted in lower mean and centroid astigmatic prediction errors, and a larger number of eyes within 0.50 diopters (D) of absolute prediction error than methods considering real measures (P < .001). Centroid prediction error (CPE) was 0.07 D at 172° for the Barrett toric calculator and 0.13 D at 174° for the Abulafia-Koch formula (combined with Holladay calculator). For methods using real posterior corneal surface measurements, CPE was 0.25 D at 173° for the Panacea calculator and 0.29 D at 171° for the ray tracing software. The Barrett toric calculator and Abulafia-Koch formula yielded the lowest astigmatic prediction errors. Directly evaluating total corneal power for toric IOL calculation was not superior to estimating it. [J Refract Surg. 2017;33(12):794-800.]. Copyright 2017, SLACK Incorporated.

To assess the safety and efficacy of microinterventional endocapsular nuclear fragmentation in moderate to severe cataracts. This was a prospective single-masked multisurgeon interventional randomised controlled trial (ClinicalTrials.gov NCT02843594) where 101 eyes of 101 subjects with grade 3-4+ nuclear cataracts were randomised to torsional phacoemulsification alone (controls) or torsional phacoemulsification with adjunctive endocapsular nuclear fragmentation using a manual microinterventional nitinol filament loop device (miLOOP group). Outcome measures were phacoemulsification efficiency as measured by ultrasound energy (cumulative dispersed energy (CDE) units) and fluidics requirements (total irrigation fluid used) as well as incidence of intraoperative and postoperative complications. Only high-grade advanced cataracts were enrolled with more than 85% of eyes with baseline best corrected visual acuity (BCVA) of 20/200 or worse in either group. Mean CDE was 53% higher in controls (32.8±24.9 vs 21.4±13.1 with miLOOP assistance) (p=0.004). Endothelial cell loss after surgery was low and similar between groups (7-8%, p=0.561) One-month BCVA averaged 20/27 Snellen in miLOOP eyes and 20/24 in controls. No direct complications were caused by the miLOOP. In two cases, capsular tears occurred during IOL implantation and in all remaining cases during phacoemulsification, with none occurring during the miLOOP nucleus disassembly part of the procedure. Microinterventional endocapsular fragmentation with the manual, disposable miLOOP device achieved consistent, ultrasound-free, full-thickness nucleus disassembly and significantly improved overall phaco efficiency in advanced cataracts.

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

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

Intracerebral Hemorrhage Caused by Cerebral Hyperperfusion after Superficial Temporal Artery to Middle Cerebral Artery Bypass for Atherosclerotic Occlusive Cerebrovascular Disease

Few papers have reported detailed accounts of intracerebral hemorrhage caused by cerebral hyperperfusion after superficial temporal artery to middle cerebral artery bypass (STA-MCA) bypass for atherosclerotic occlusive cerebrovascular disease. We report a case of vasogenic edema and subsequent intracerebral hemorrhage caused by the cerebral hyperperfusion syndrome (CHS) after STA-MCA bypass for atherosclerotic occlusive cerebrovascular disease disease without intense postoperative blood pressure control. A 63-year-old man with repeating left hemiparesis underwent magnetic resonance angiography (MRA), which revealed right internal carotid artery (ICA) occlusion. We performed a double bypass superficial temporal artery (STA)–middle cerebral artery (MCA) bypass surgery for the M2 and M3 branches. While the patient’s postoperative course was relatively uneventful, he suffered generalized convulsions, and computed tomography revealed a low area in the right frontal lobe on Day 4 after surgery. We considered this lesion to be pure vasogenic edema caused by cerebral hyperperfusion after revascularization. Intravenous drip infusion of a free radical scavenger (edaravone) and efforts to reduce systolic blood pressure to <120 mmHg were continued. The patient experienced severe left hemiparesis and disturbance of consciousness on Day 8 after surgery, due to intracerebral hemorrhage in the right frontal lobe at the site of the earlier vasogenic edema. Brain edema associated with cerebral hyperperfusion after STA-MCA bypass for atherosclerotic occlusive cerebrovascular disease should be recognized as a risk factor for intracerebral hemorrhage. The development of brain edema associated with CHS after STA-MCA bypass for atherosclerotic occlusive cerebrovascular disease requires not only intensive control of blood pressure, but also consideration of sedation therapy with propofol.

Most published articles regarding orthopedic- and trauma-related femoral artery pseudoaneurysms (FAPs) are case reports in English. Reported cases are often associated with a literature review but actually provide little robust data. We wanted to summarize the current knowledge on diagnostic and therapeutic features of these FAPs. A new case of superficial FAP is described followed by a review of the literature. A bibliographic search was performed online (PubMed, ScinceDirect) from 1964 to 2015 using the descriptors "traumatic femoral pseudoaneurysm, orthopedic surgery, osteochondroma". A total of 64 cases of FAPs was analyzed. There were 50 men with an average age of 40.72±26.45 years old. The most common clinical presentation was painful swelling (34%). Arteriography was the commonest radiological investigation used (63%). The main etiologies were orthopedic injuries (47%), surgery of the upper thigh (30%) and femoral osteochondromas (23%). Arterial injuries included superficial femoral (47%) and profunda femoris artery (50%). The treatment was open surgery (56%) or endovascular repair (36%). Deep femoral artery and its branches were embolized (47%) or ligated (38%). Endovascular stenting was performed in 30% of posttraumatic FAPs. All FAPs relating to osteochondromas were repaired surgically. Postoperative courses were uneventful in 95% of patients. Endovascular embolization is preferred in management of postsurgical FAPs which have usually involved the deep femoral artery. Endovascular stenting graft may be proposed for posttraumatic FAPs, for which the superficial femoral trunk is the most often involved vessel. Surgical repair should be performed when endovascular stenting graft is not feasible. Surgical repair is mandatory for all FAPs secondary to traumatic exostoses. Copyright © 2015 Elsevier Masson SAS.

The treatment of isolated segmental, sectoral and right hepatic bile duct injuries is controversial. Nineteen patients were treated over a 26-year period. Group one was comprised of 4 patients in whom the injury was primarily repaired during the original surgery; 3 over a T-tube, 1 with a Roux-en-Y. These patients had an uneventful recovery. The second group consisted of 5 patients in whom the duct was ligated; 4 developed infection, 3 of which required drainage and biliary repair. Two patients had good long-term outcomes; the third developed a late anastomotic stricture requiring further surgery. The fourth patient developed a small bile leak and pain which resolved spontaneously. The fifth patient developed complications from which he died. The third group was comprised of 4 patients referred with biliary peritonitis; all underwent drainage and lavage, and developed biliary fistulae, 3 of which resolved spontaneously, 1 required Roux-en-Y repair, with favorable outcomes. The fourth group consisted of 6 patients with biliary fistulae. Two patients, both with an 8-wk history of a fistula, underwent Roux-en-Y repair. Two others also underwent a Roux-en-Y repair, as their fistulae showed no signs of closure. The remaining 2 patients had spontaneous closure of their biliary fistulae. A primary repair is a reasonable alternative to ligature of injured duct. Patients with ligated ducts may develop complications. Infected ducts require further surgery. Patients with biliary peritonitis must be treated with drainage and lavage. There is a 50% chance that a biliary fistula will close spontaneously. In cases where the biliary fistula does not close within 6 to 8 wk, a Roux-en-Y anastomosis should be considered. PMID:19322912

To assess the impact of postoperative complications on full in-hospital costs per case. Rising expenses for complex medical procedures combined with constrained resources represent a major challenge. The severity of postoperative complications reflects surgical outcomes. The magnitude of the cost created by negative outcomes is unclear. Morbidity of 1200 consecutive patients undergoing major surgery from 2005 to 2008 in a tertiary, high-volume center was assessed by a validated, complication score system. Full in-hospital costs were collected for each patient. Statistical analysis was performed using a multivariate linear regression model adjusted for potential confounders. This study population included 393 complex liver/bile duct surgeries, 110 major pancreas operations, 389 colon resections, and 308 Roux-en-Y gastric bypasses. The overall 30-day mortality rate was 1.8%, whereas morbidity was 53.8%. Patients with an uneventful course had mean costs per case of US$ 27,946 (SD US$ 15,106). Costs increased dramatically with the severity of postoperative complications and reached the mean costs of US$ 159,345 (SD US$ 151,191) for grade IV complications. This increase in costs, up to 5 times the cost of a similar operation without complications, was observed for all types of investigated procedures, although the magnitude of the increase varied, with the highest costs in patients undergoing pancreas surgery. This study demonstrates the dramatic impact of postoperative complications on full in-hospital costs per case and that complications are the strongest indicator of costs. Furthermore, the study highlights a relevant savings capacity for major surgical procedures, and supports all efforts to lower negative events in the postoperative course.

A 3.3-year-old male alpaca, weighing 60 kg was referred for investigation of a severe left forelimb lameness of 4 weeks duration. A scapulohumeral subluxation had been diagnosed radiographically by the referring veterinarian. Based on clinical, ultrasonographic and radiographic findings the diagnosis of cranio-lateral subluxation of the left humeral head was confirmed. In addition, a full thickness lesion (approximately 1×1 cm) of the articular cartilage on the caudomedial aspect of the humeral head was diagnosed by arthroscopy. Treatment included open reduction with internal fixation. Severe muscle contraction and local tissue fibrosis around the scapulohumeral joint (SHJ) required osteotomy of the acromion 3 cm proximal to the distal acromial edge, to allow adequate access. Internal stabilisation was achieved by placing tension band sutures between one cortical screw in the scapular neck and two cortical screws, with washers, craniolaterally on the greater tubercle of the humerus. Post-surgery, a carpal flexion sling was applied with the carpus maintained in 70° flexion for 4 weeks to avoid postoperative weight-bearing. An exercise programme was started 8 days after surgery and continued for 12 weeks. The alpaca had an uneventful postsurgical recovery and showed no lameness after 8 weeks. The long-term outcome was excellent; 21 months after surgery the alpaca was sound and the range of movement of the left SHJ was equal to the right SHJ. Even in this chronic case of subluxation of the SHJ of 4 weeks duration, surgical treatment using osteotomy of the acromion, open reduction and internal fixation with extracapsular scapulohumeral tension sutures resulted in an excellent long-term outcome in this alpaca, despite the presence of a cartilage lesion.

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 specificity of 91% and a sensitivity of 96% in this series. A quantitative method can be used to identify eyes at risk for developing ectasia after LASIK that, if validated, represents a significant improvement over current screening strategies.

Although intracranial extension of juvenile nasopharyngeal angiofibroma (JNA) occurs commonly, intradural penetration is extremely rare. Management of such tumors is a challenging issue in skull-base surgery, necessitating their removal via combined approaches. In this work, we share our experience in management of extensive intradural JNA. In a university hospital-based setting of 2 tertiary care academic centers, retrospective chart of 6 male patients (5 between 15 and 19 years old) was reviewed. Patients presented chiefly with nasal obstruction, epistaxis, and proptosis. One of them was an aggressive recurrent tumor in a 32-year-old patient. All cases underwent combined transnasal, transmaxillary, and craniotomy approaches assisted by the use of image-guided endoscopic surgery, with craniotomy preceding the rhinosurgical approach in 3 cases. Adding a transcranial approach to the transnasal and transmaxillary endoscopic approaches provided 2-sided exposure and appreciated access to the huge intradural JNAs. One postoperative cerebrospinal fluid leak and 1 postoperative recurrence at the site of infratemporal fossa were treated successfully. Otherwise, the course was uneventful in the remaining cases. Management of intracranial intradural JNA requires a multidisciplinary approach of combined open and endoscopic-assisted rhinosurgery and neurosurgery, because of greater risk for complications during the dissection. Carotid rupture and brain damage remain 2 catastrophic complications that should always be kept in mind. A combined rhinosurgical and neurosurgical approach also has the advantage of very modest cosmetic complications. © 2015 ARS-AAOA, LLC.

Medullary carcinoma is a rare type of colorectal adenocarcinoma, and omental infarction is a rare cause of acute abdomen. A 72-year-old woman underwent single-incision laparoscopic right hemicolectomy for ascending colon cancer. Pathological examination showed a medullary carcinoma (MC) of T4aN0M0 Stage IIB. Her postoperative course was uneventful, and she was discharged on postoperative day (POD) 6. From POD 7, she suffered from fever, and she returned to the hospital on POD 9. Plain computed tomography showed free air beside the anastomotic site around the elevated density of fat tissue and gallbladder wall thickening with a gallstone. Suspecting anastomotic leakage with acute cholecystitis, probe laparotomy was performed. Intraoperative observation confirmed omental infarction with acute cholecystitis, and no leakage was found at the anastomotic site. Therefore, the necrotic part of the greater omentum was resected, and cholecystectomy was performed. She has remained well, with no evidence of recurrent cancer during the 12 months of follow-up without chemotherapy after the surgery for MC of the ascending colon. MC should be distinguished from other more aggressive, non-glandular tumors of the colon because MC appears to have a better survival outcome than undifferentiated colon adenocarcinoma. Omental infarction should be considered in the differential diagnosis of acute abdomen after surgery. A rare case of medullary carcinoma of the ascending colon followed by infarction of the greater omentum mimicking anastomotic leakage is presented.

A 3-year-old girl presented with osmotic demyelination syndrome after undergoing uneventful neuroendoscopic cystostomy for a growing cystic suprasellar craniopharyngioma following microscopic subtotal resection 1 year previously. Endocrinopathy had well been controlled by hormone replacement therapy and administration of 1-amino-8-d-arginine-vasopressin with serum sodium concentration within the normal range. She presented generalized seizure and fever on postoperative day 7, with hyponatremia beginning on postoperative day 4 and deteriorating despite frequent correction. The serum sodium concentration began to fluctuate on the same day, in the range 111-164 mEq/l, which lasted for 2 weeks, refractory for intense management. Her body temperature also fluctuated between hypo- and hyperthermia not correlated with serum inflammatory markers. Her conscious disturbance progressively deteriorated with spastic paraparesis. T(2)-weighted magnetic resonance (MR) imaging taken on postoperative day 19 revealed hyperintense areas in the pons, external capsule, bilateral thalami, and basal nuclei, which had not been recognized before, suggesting osmotic demyelination syndrome causing central pontine and extrapontine myelinolysis. MR imaging taken on postoperative days 230 and 360 showed some diminished lesions but others persisted and resulted in a cavity. The patient's depressed conscious level did not improve. Suprasellar craniopharyngioma with long-standing hypothalamic dysfunction may be associated with severe osmotic demyelination syndrome even after less invasive surgery, so serum sodium derangement after surgery should be promptly corrected even if only subtle signs are present.

Deviated cartilages structures of the nose can be affected by nasal muscles, and deviation becomes conspicuous when the patient smiles. This condition depends on activity of nasal muscles, particularly the levator labii alaeque nasi muscle. A total of 124 septorhinoplasty operations were performed to correct dorsal concave septal deviation between 2005 and 2009 years. The 70 women and 54 men included in the study had an average age of 28 years. The average follow-up period was 12 months. Open septorhinoplasty was preferred in all cases. The medial part of the levator labii alaeque nasi muscle was extensively dissected from the lateral crus and surrounding tissues. The lateral crura of the alar cartilages were separated from the upper lateral cartilages in the scroll area. The dorsal septal deviation was corrected by combination of bilateral spreader grafts, which reinforced cartilage with horizontal control sutures. Early postoperative period was uneventful. Nasal obstruction was reduced after surgery, and significant subjective postoperative improvements were observed in all patients. Comparison of preoperative and postoperative photographs demonstrated improved dorsal nasal contour. Revision operation was performed in 3 cases. The corrected septal cartilage was in a good position in all revised cases; therefore, septal surgery was not performed in the revision operations. In conclusion, surgical disruption of the anatomic relationship between the muscle with the dorsal septal cartilage and reinforcement of the dorsal septal cartilage with spreader grafts and horizontal control sutures can decrease risk of recurrence.

Periodontal-endodontic lesion of a three-rooted maxillary premolar: report of a case.

A 43-year-old African American male initially presented for a dental evaluation of a recurrent swelling on the buccal aspect of tooth #12. His medical history was unremarkable except for a 20-pack year history of smoking. He was eventually diagnosed as having a necrotic pulp #12, and received root canal treatment. The patient's problem was unresolved, and he was subsequently referred for a periodontal evaluation with a presumptive diagnosis of a periodontal abscess. A flap was reflected from teeth #11 through #15. A buccal furcation invasion was discovered on #12. Shortly thereafter, three distinct roots with three grade III furcation invasions were located. The tooth was deemed untreatable, and was extracted. The thin buccal plate of the extraction socket was preserved using freeze-dried bone allograft to facilitate future prosthodontic replacement. Healing was uneventful. Periodontal open flap debridement surgery was provided for the remainder of the mouth, and the patient was placed on a 3-month recall program. Periodontitis associated with endodontic lesions are among the most daunting diagnostic and therapeutic challenges faced by periodontists. This is particularly true for maxillary premolars with multiple roots. The tooth in this case, once periodontally involved, had a very poor prognosis. The prognosis was further compromised by the pulpal involvement. Therapy consisted of extraction of the tooth to relieve the patient's discomfort and treating the adjacent teeth with periodontal open flap debridement surgery. A review of the literature pertinent to the diagnosis and management of periodontal-endodontic lesions is also presented.

Introduction Laser vision correction for hyperopia is challenging. The purpose of the study was to assess the refractive outcomes of femtosecond-assisted laser in situ keratomileusis (LASIK) for hyperopic correction using wavefront-optimized ablation profiles. Methods This retrospective case series study included 20 Egyptian patients (40 eyes) with hyperopia or hyperopic astigmatism with a mean manifest refraction spherical equivalent (MRSE) of +2.55D±1.17 (range from +1.00 to +6.00) who had uneventful femtosecond-a assisted LASIK with wavefront-optimized aspheric ablation profile using refractive surgery suite (WaveLight FS200 Femtosecond Laser and WaveLight EX500 Excimer Laser) performed in the Research Institute of Ophthalmology and International Eye Hospital, Giza, Egypt. Statistical analysis was done using Microsoft Excel (Microsoft Corporation, Seattle, WA, USA). Results The procedure significantly reduced the MRSE and cylinder post-operatively (95% were ± 0.50D and 100% ± 1.00 D), with stability of refraction and UDVA over the follow-up period (up to 12 months) after surgery. No eye lost any line of the CDVA, which reflects the excellent safety profile of the procedure; on the other hand, one eye (5%) gained one line and one eye (5%) even gained two lines. There were no significant complications during the procedure. Conclusions Femtosecond-assisted laser in situ keratomileusis for hyperopia showed predictable, effective, and safe refractive outcomes that were stable through 12 months. Longer follow-up period is required to detect any further regression PMID:28461870

Cerebrospinal fluid (CSF) hypovolemia is a common neurosurgical condition, which may be spontaneous or iatrogenic. At our institution, a substantial number of the reported cases of early post-operative CSF hypovolemia were identified to have unintentional or unrecognized post-operative continuous excessive CSF leakage. Cases who presented with post-operative CSF hypovolemia several days after uneventful intracranial surgeries without continuous CSF leakage were rarely reported. A retrospective review of the medical records of these patients was performed to identify those patients who developed early post-operative CSF hypovolemia without the presence of post-operative continuous CSF leakage. A total of 7 patients, 5 of which were males, were identified in this retrospective study. They experienced CSF hypovolemia between days 1 and 7 after emergency or scheduled intracranial surgeries. Ventricular collapse, cisternal effacement and midline shift are the most common radiological observations. With early diagnosis and management, 4 of the patients achieved a Glasgow Outcome Scale (GOS) score of 5, 1 achieved a GOS score of 4 and the remaining 2 had a GOS score of 3. No mortality was noted in this series. Although rare in incidence, early post-operative CSF hypovolemia may occur without the existence of post-operative continuous CSF leakage. When the diagnosis of CSF hypovolemia is reached, factors that may exacerbate CSF compensation should be promptly terminated. Trendelenburg position and sufficient intravenous hydration are practical and effective managements, and CSF hypovolemia may thereby be reversed in a substantial number of patients.

Abstract Rationale: Precise bony reduction and reconstruction of optimal contour in treating comminuted mandibular fractures is very difficult using traditional techniques and devices. The aim of this report is to introduce our experiences in using virtual surgery and three-dimensional (3D) printing technique in treating this clinical challenge. Patient concerns: A 26-year-old man presented with severe trauma in the maxillofacial area due to fall from height. Diagnosis: Computed tomography images revealed middle face fractures and comminuted mandibular fracture including bilateral condyles. Interventions and outcomes: The computed tomography data was used to construct the 3D cranio-maxillofacial models; then the displaced bone fragments were virtually reduced. On the basis of the finalized model, a customized titanium mesh tray was designed and fabricated using selective laser melting technology. During the surgery, a submandibular approach was adopted to repair the mandibular fracture. The reduction and fixation were performed according to preoperative plan, the bone defects in the mental area were reconstructed with iliac bone graft. The 3D-printed mesh tray served as an intraoperative template and carrier of bone graft. The healing process was uneventful, and the patient was satisfied with the mandible contour. Lessons: Virtual surgical planning combined with 3D printing technology enables surgeon to visualize the reduction process preoperatively and guide intraoperative reduction, making the reduction less time consuming and more precise. 3D-printed titanium mesh tray can provide more satisfactory esthetic outcomes in treating complex comminuted mandibular fractures.

Esophageal surgery has been recognized as very challenging for surgeons and risky for patients. Thoracoscopic approach have proved its benefit in esophageal surgery but has some drawbacks as tremor and limited degrees of freedom, contra-intuitive movements and fulcrum effect of the surgical tools. Robotic technology has been developed with the intent to overcome these limitations of the standard laparoscopy or thoracoscopy. These benefits of robotic procedure are most advantageous when operating in remote areas difficult to reach as in esophageal surgery. The aim of this paper is to present our small experience related with robotic approach in benign and malignant esophageal tumors and critically revise the evidence available about the use of the robotic technology for the treatment of these pathology. Methods: From January 2008 to September 2016 robotic surgery interventions related with benign or malignant esophageal tumors were performed in "Dan Setlacec" Center for General Surgery and Liver Transplantation of Fundeni Clinical Institute in seven patients. This consisted of dissection of the entire esophagus as part of an abdomino-thoracic-cervical procedure for esophageal cancer in 3 patients and the extirpation of an esophageal leiomyoma in 3 cases and a foregut esophageal cyst in one case. Results: All procedures except one were completed entirely using the da Vinci robotic system. The exception was the first case - a 3 cm leiomyoma of the inferior esophagus with ulceration of the superjacent esophageal mucosa. Pathology reports revealed three esophageal leiomyoma, one foregut cyst and three squamous cell carcinomas with free of tumor resection margins. The mean number of retrieved mediastinal nodes was 24 (22 - 27). The postoperative course was uneventful in four cases, in the other three a esophageal fistula occurred in the converted leiomyoma case (closed in the 14th postoperative day), a prolonged drainage in one esophageal cancer case and a temporary right recurrent nerve palsy in an other one. One patient with esophageal cancer and all patients with benign lesions are alive with no signs of recurrence and no symptomatology. Our experience is limited and we cannot conclude for the long term benefits of robotic surgery for esophageal tumors. In our experience the early outcomes were better then using classic open approach, but similar with the cases performed by thoracoscopic approach. We have noticed significant advantages of robotic surgery in relation of lymph node retrieval, leiomyoma dissection safe from esophageal mucosa and suturing. Ergonomics for the surgeon was incomparable better then with the thoracoscopic approach. Celsius.

Partial Cystectomy for Atypical Isolated Recurrence of Ovarian Adenocarcinoma - A Case Report and Literature Review.

2017-01-01

Most cases with advanced-stage epithelial ovarian malignancies will experience recurrent disease at a certain moment of their evolution, even if maximal cytoreductive surgery has been performed at the moment of initial diagnosis. However, it seems that the best therapeutic strategy, in case of relapse, remains aggressive re-resection, with complete cytoreduction being the most efficient way to improve survival. We present the case of a 55-year-old patient diagnosed with an isolated pelvic recurrence after stage IIIC surgically-treated ovarian cancer three years after primary cytoreduction. Intraoperatively, the diagnosis of an isolated pelvic recurrence invading the urinary bladder was confirmed. The recurrent tumor was resected en bloc with partial cystectomy. The postoperative course was uneventful, while histopathological studies confirmed the presence of a poorly differentiated epithelial ovarian recurrent adenocarcinoma. At two year follow-up, the patient is free of any recurrent disease. Isolated pelvic recurrences after surgically-treated ovarian adenocarcinomas can be safely removed and might improve survival.

A 58-year-old female without cardiovascular risk factors, was going to be operated to repair the rotator cuff. Induction and interscalene brachial plexus block were uneventful, but after her placement for surgery the patient started with severe bronchospasm, hypotension, cutaneous allergic reaction and ST elevation on the electrocardiogram. An anaphylactic shock was suspected and treated but until the perfusion of nitroglycerina was started no electrocardiographic changes resolved. After necessary diagnostic test the final diagnosis was variant I of Kounis syndrome due to cefazolin and rocuronium. Ephinephrine is the cornerstone of treatment for anaphylaxis but should we use it if the anaphylactic reaction is also accompanied by myocardial ischemia? The answer is that we should not use it because myocardial ischemia in this syndrome is caused by vasospasm, so it would be more useful drugs such as nitroglycerin. But what if we do not know if it is a Kounis syndrome or not? In this article we report our experience that maybe could help you in a similar situation.

2016-01-01

Herein, we report a case of nonarteritic anterior ischemic optic neuropathy (NAION) following uneventful pars plana vitrectomy for macular hole treatment. A 56-year-old previously healthy woman presented with a full-thickness macular hole in right eye (OD) and small cup-to-disc ratios in both eyes. Five days after surgery, she noticed sudden painless loss of vision in OD and was found to have an afferent pupillary defect and intraocular pressure of 29 mmHg. Fundus examination showed right optic disc edema and the resolution of a macular hole with an inferior altitudinal visual field defect. Erythrocyte sedimentation rate, C-reactive protein levels, and general physical examination findings were normal. She was treated with hypotensive eyedrops and oral prednisone, resulting in mild visual improvement and a pale optic disc. A combination of face-down position and increased intraocular pressure due to a small optic disc cup were considered as potential mechanisms underlying NAION in the present case. Vitreoretinal surgeons should be aware of NAION as a potentially serious complication and be able to recognize associated risk factors and clinical findings.

Glutaric aciduria type 1 (GA1) is a rare, inherited mitochondrial disorder that results from deficiency of mitochondrial glutaryl-CoA dehydrogenase. Most patients develop neurological dysfunction early in life, which leads to severe disabilities. We present a 37-month-old girl with GA1 manifested as macrocephaly and hypotonia who received comprehensive dental restoration surgery under general anesthesia with sevoflurane. She was placed on specialized fluid management during a preoperative fasting period and anesthesia was administered without complications. All the physiological parameters, including glucose and lactate blood levels and arterial blood gas were carefully monitored and maintained within normal range perioperatively. Strategies for anesthetic management should include prevention of pulmonary aspiration, dehydration, hyperthermia and catabolic state, adequate analgesia to minimize surgical stress, and avoidance of prolonged neuromuscular blockade. We administered general anesthesia with sevoflurane uneventfully, which was well tolerated by our patient with GA1. Additionally, communication with a pediatric geneticist and surgeons should be undertaken to formulate a comprehensive anesthetic strategy in these patients. Copyright © 2014.

Rotationplasty is a limb-sparing surgical option in lower limb malignancies. Sciatic or tibial nerve encasement has been considered an absolute contraindication to this procedure. We report a case of an 18-month-old girl with a rhabdomyosarcoma that affected the leg and popliteal fossa, with neurovascular involvement. Knee and proximal leg intercalary resection was performed followed by reconstruction with free microvascular rotationplasty and neurorraphy from tibial division of sciatic nerve to sural and tibial nerves, and from saphenous nerve to superficial peroneal nerve. Postoperative course was uneventful and ambulation with a provisional prosthesis was restarted during the sixth week after surgery. Bone consolidation was observed after two months. Eighteen months later, the patient had a good gait pattern with a below-knee prosthesis and had recovered sensation in the whole foot and ankle area. This case shows that rotationplasty with nerve repair may provide a sensate stump, which is vital for successful prosthetic adaptation. We believe it may be considered as an alternative to above-knee amputation in tumors with sciatic involvement. © 2017 Wiley Periodicals, Inc.

Roux-en-Y hepaticojejunostomy anastomosis is the treatment of choice for common hepatic duct injury type E2. It has been performed laparoscopically with the advancement of laparoscopic skill. Recently, a telemanipulative robotic surgical system was introduced, providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field. We present a case of 36-year-old female patient who had undergone elective cholecystectomy 2 mo ago for gall stones and had a common bile duct injury during surgery. As the stricture was old and complete it could not be tackled endoscopically. We did a laparoscopic assisted adhesiolysis followed by robotic Roux-en-Y hepaticojejunostomy. No intraoperative complications or technical problems were encountered. Postoperative period was uneventful and she was discharged on the 4th postoperative day. At follow-up, she is doing well without evidence of jaundice or cholangitis. This is the first reported case of robotic hepaticojejunostomy following common bile duct injury. The hybrid technique gives the patient benefit of laparoscopic adhesiolysis and robotic suturing. PMID:25684934

The aim of the study was a clinical evaluation of an intraocular lens (IOL) with a segmental multifocal optic design and near addition of + 3.0 D as part of a CE approval study. In a multicenter study the LENTIS Mplus LS-312 MF IOL (Oculentis) was implanted in 134 eyes of 79 patients with a mean age of 68 ± 12 years. The multifocality is achieved by implementation of a distance part and a segmented near sector. Three months after surgery, uncorrected and best corrected distance visual acuity (UCDVA and BCDVA, respectively), near visual acuity (UCNVA and BCNVA, respectively), contrast vision and patient satisfaction (questionnaire) were evaluated. The IOLs were implanted uneventfully either unilaterally or bilaterally and 3 months postoperatively (n = 86 eyes) the following mean visual acuities were obtained (logMAR): UCDVA = 0.05, BCDVA = - 0.01, UCNVA = 0.09 and BCNVA = 0.02. Contrast sensitivity (n = 25 eyes) was within normal limits. Of the 66 questioned patients 10.6% spontaneously reported halos and 3% glare. This new innovative multifocal IOL concept showed very good functional results as well as high patient satisfaction.

Meckel's diverticulum (MD) is a common congenital anomaly of the gastrointestinal tract, the majority of cases of which are clinically silent. Patients with asymptomatic MD can unexpectedly develop acute abdominal pain. Making a diagnosis of MD is often difficult due to the lack of specific symptoms caused by this condition. Diagnostic laparotomy can be useful for making an accurate and prompt diagnosis of complicated MD. We herein describe a pediatric case of torsion of a MD in whom we performed laparoscopic-assisted emergency surgery. The patient was an 11-year-old male who developed sudden severe right lower abdominal pain. Clinical and laboratory findings were suggestive of appendicitis, however computed tomography scans showed a large cystic mass in the pelvis. Exploratory laparoscopy led to a diagnosis of torsion of a MD, and wedge resection of the gangrenous MD was performed through an umbilical port incision. The patient's postoperative course was uneventful. We conclude that diagnostic laparoscopy followed by laparoscopy-assisted Meckel's diverticulectomy via an umbilical incision is useful in the treatment of acute abdomen caused by MD. PMID:23466748

Background Despite of recent development of imaging modalities, congenital intrahepatic portosystemic shunt (IPSS) is rarely diagnosed. Therefore, living donor liver transplantation using a liver graft with IPSS has not been previously published. Materials and Methods We report a 28-year-old male patient with end-stage liver disease secondary to Wilson disease. His 26-year-old brother was a potential living donor, who had an IPSS of 25 mm in diameter at segment 6 as shown by computed tomography. Liver function tests were normal, and blood ammonia concentration was in the upper limit of normal. Results Living donor liver transplantation was uneventfully performed. After surgery, a recipient liver function tests showed a quick recovery, and serum ammonia levels were consistently normal. Although thrombosis inside the IPSS was confirmed by computed tomography on postoperative day 21, this thrombosis disappeared at 3 months posttransplant with anticoagulants. Currently (12 months posttransplant), the patient has fully recovered, and the IPSS is still the same size. Conclusions Based on our experience, liver allografts with IPSS can be accepted as potential liver allografts. PMID:27500240

Iatrogenic Diversion of Inferior Vena Cava into Left Atrium after Surgery for a Rare Combination of Congenital Heart Diseases

Atrial septal defect (ASD) is a common congenital anomaly that has low surgical mortality and morbidity. We report a very rare case of a low-lying ASD, combined with the drainage of the inferior vena cava and the left superior vena cava into the left atrium. This combination was associated with an unroofed coronary sinus. We also describe an iatrogenic surgical diversion of the inferior vena cava into the left atrium with its complication. The patient presented with moderate cyanosis and was referred for elective ASD repair. He underwent surgical repair of the ASD after transthoracic echocardiography. Early postoperative right-to-left shunting with cyanosis and hypoxia was associated with abdominal complications. Surgical re-exploration revealed the diversion of the inferior vena cava into the left atrium, which was repaired with a pericardial patch. Peptic ulcer perforation was repaired after abdominal laparotomy. The patient had an uneventful recovery and was discharged home on the 17th postoperative day. One-year follow-up revealed no recurrence of cyanosis or residual ASD on echocardiography. PMID:27928261

Fat-forming solitary fibrous tumors arising from the kidney are extremely rare, with only few cases reported so far. We report the case of a 49-year-old patient investigated for lumbar pain and diagnosed preoperatively with a large retroperitoneal tumor destroying the right kidney. The patient was submitted to surgery, the tumor being resected en bloc with right nephrectomy. The histopathological studies demonstrated the presence of a hemangiopericytoma-like tumor with adipocytary component; the immunohistochemical studies demonstrated the presence of cluster of differentiation 34 (CD34), while human melanoma black (HMB45) staining was negative. Therefore, the diagnostic of fat-forming solitary fibrous tumor of the kidney was established. The postoperative outcome was uneventful, the patient being discharged on the sixth postoperative day. In conclusion, although fat-forming solitary fibrous tumor of the kidney is a very rare entity, this diagnosis should be taken into consideration whenever a large retroperitoneal mass with high adipose content and renal invasion is described at the preoperative studies.

2011-01-01

The purpose of this study was to analyze the pathogenic mechanisms, clinical presentation, and surgical treatment of cervical disc herniation without external trauma. Between 2004 and 2008, 9 patients with cervical disc herniation and no antecedent history of trauma were diagnosed with cervical disc herniation and underwent surgical decompression. Pathogenic mechanisms, clinical presentation, surgical treatment, and prognosis were analyzed retrospectively. In 6 patients, herniation resulted from excessive neck motion rather than from external trauma. An injury from this source is termed an endogenous-lesioned injury. Patients exhibited neurologic symptoms of compression of the cervical spinal cord or nerve roots. In the other 3 patients, no clear cause for the herniation was recorded, but all patients had a desk job with long periods of head-down neck flexion posture. After surgery, all patients experienced a reduction in their symptoms and an uneventful recovery. Cervical disc herniation can occur in the absence of trauma. Surgical decompression is effective at reducing symptoms in these patients, similar to other patients with cervical disc herniation. Surgical treatment may be considered for this disorder when the herniation becomes symptomatic.

We are reporting the first-to our knowledge-case of duodenal Plexiform Fibromyxoma causing obscure upper gastrointestinal bleeding. Plexiform fibromyxoma triggered recurrent upper gastrointestinal bleeding episodes in a 63-year-old man who remained undiagnosed, despite multiple hospitalizations, extensive diagnostic workups and surgical interventions (including gastrectomies), for almost 17 years. During hospitalization for the last bleeding episode, an upper gastrointestinal endoscopy revealed an intestinal hemorrhagic nodule. The lesion was deemed unresectable by endoscopic means. An abdominal computerized tomography disclosed no further lesions and surgery was decided. The lesion at operation was found near the edge of the duodenal stump and treated with pancreas-preserving duodenectomy (1st and 2nd portion). Postoperative recovery was mainly uneventful and a 20-month follow-up finds the patient in good health with no need for blood transfusions.Plexiform fibromyxomas stand for a rare and widely unknown mesenchymal entity. Despite the fact that they closely resemble other gastrointestinal tumors, they distinctly vary in clinical management as well as the histopathology. Clinical awareness and further research are compulsory to elucidate its clinical course and prognosis.

Summary Background: Acute lobar collapse caused by a reflex bronchoconstriction was previously reported to occur during the induction of anesthesia, however there are no reports on its occurrence during the emergence period. Case Report: A 56-year-old morbidly obese woman was scheduled for surgery due to a gastric ulcer perforation. Anesthesia was induced with thiopental 500 mg, fentanyl and rocuronium, and maintained with sevoflurane in a N2O/O2 mixture. The operative procedure and anesthesia were uneventful; however, the patient developed a sudden decrease in SaO2 and blurring of consciousness after extubation. She was re-intubated and ventilated with 100% O2. Arterial blood gas analysis at that time showed respiratory acidosis and hypoxemia. Further work-up revealed a bronchospasm-induced right upper lobe atelectasis, which occurred immediately after tracheal extubation. The patient was successfully treated using mechanical ventilation and bronchodilators. Conclusions: Bronchospasm may cause acute lobar atelectasis immediately after tracheal extubation. Morbid obesity and the use of 100% oxygen may facilitate atelectasis formation during emergence from anesthesia. PMID:23569513

Purpose We report here the case of a patient with anterior segment migration of intravitreal dexamethasone implant as well as its management and outcome. Methods The patient had the following sequence of events: complicated cataract surgery, iris-sutured intraocular lens implant, followed by cystoid macular edema treated with intravitreal Avastin, retinal vein occlusion treated with intravitreal dexamethasone implant, corneal decompensation treated with Descemet stripping automated endothelial keratoplasty (DSAEK), and finally recurrence of macular edema treated with repeated intravitreal dexamethasone implant. Results Dexamethasone implant had completely dissolved from the eye 12 weeks after insertion without any complication. Conclusion A conservative approach with regular monitoring in the situation of a quiet anterior segment without any corneal decompensation can provide enough time for the implant to dissolve without causing any complication to the involved eye, avoiding any additional surgical intervention, as presented in this case report. Despite the fact that the implant was left for natural dissolution, there were no adverse effects related to the graft or the eye. PMID:29643797

A nulliparous non-descript mare was presented with a complaint of dystocia. The mare was recumbent and physical examination revealed that the animal was in shock. There was no straining and foetal forelimbs were visible outside the vulva. The foetus was dead as there was no pedal reflex. Vaginal examination revealed anterior presentation with dorso-sacral position and rigid lateral head deviation. Pre-operatively, the mare was given 5 ml Tetanus toxoid and 3 g Ceftriaxone as intramuscular injection, and 5 ml Dexamethasone in 15 L of 5% Dextrose Normal Saline (DNS) as intravenous (i/v) infusion. As pelvic space was inadequate and the mal posture was not correctable, manual correction or foetotomy could not be attempted and therefore caesarean section was planned. Condition of the animal warranted the use of local anaesthetic infiltration instead of general anesthesia. Post-operative care included intravenous fluids, anti-inflammatory/analgesics and daily antiseptic dressing. The owner reported uneventful recovery. The authors would like to conclude the case as a rare emergency caesarean in equine where the surgery was done with animal in lateral recumbency employing a Marcenac incision under local anaesthesia.

Extended maxillotomy for skull base access in contemporary management of chordomas: Rationale and technical aspect.

PubMed

Abdul Jalil, Muhammad Fahmi; Story, Rowan D; Rogers, Myron

2017-05-01

Minimally invasive approaches to the central skull base have been popularized over the last decade and have to a large extent displaced 'open' procedures. However, traditional skull base surgery still has its role especially when dealing with a large clival chordoma where maximal surgical resection is the principal goal to maximize patient survival. In this paper, we present a case of a 25year-old male patient with chordoma in the inferior clivus which was initially debulked via a transnasal endoscopic approach. He unfortunately had a large recurrence of tumor requiring re-do resection. With the aim to achieve maximal surgical resection, we then chose the technique of a transoral approach with Le Fort 1 maxillotomy and midline palatal split. Post-operative course for the patient was uneventful and post-operative MRI confirmed significant debulking of the clival lesion. The technique employed for the surgical procedure is presented here in detail as is our experience over two decades using this technique for tumors, inflammatory lesions and congenital abnormalities at the cranio-cervical junction.

Hepatico-portal fistula (HPF) is a rare condition, most often of post-traumatic or iatrogenic origin and occasionally secondary to a ruptured aneurysm of the hepatic artery into the portal vein. HPF in extrahepatic locations often results in portal hypertension (PHT). While Doppler ultrasound, CT angiography, and magnetic resonance angiography are usually demonstrative, arteriography remains indispensable to clarify the exact anatomical configuration. In the treatment of these arteriovenous (AV) fistulas, open surgical approaches have increasingly given way to radiological embolization techniques, especially in intrahepatic locations, but surgery remains indicated for AV fistulas of the hepatic pedicle where maintenance of hepatic arterial flow is a priority of treatment. We report a patient who had an AV fistula of the hepatic pedicle with resultant PHT presenting 5 years after open abdominal trauma. Treatment was surgical; the immediate and long-term postoperative course was uneventful with regression of PHT. Through analysis of this case and a review of the literature, we discuss the clinical, paraclinical, therapeutic, and prognostic features of this lesion. Copyright © 2010.

European experience in endoscopic mucosal resection (EMR) for early gastric cancer is still relatively low, since early stomach cancer is diagnosed at a much lower rate in Europe than in Japan and generally operable patients are referred to surgery for radical resection. Endoscopic mucosal resection or mucosectomy was developed as a promising technology to diagnose and treat mucosal lesions in the esophagus, stomach and colon. In contrast to surgical resection, EMR allows "early cancers" to be removed with a minimal cost, morbidity and mortality. We present the case of a patient with hepatic cirrhosis incidentally diagnosed with an elevated-type IIa early gastric cancer. Echoendoscopy was performed in order to assess the depth of invasion into the gastric wall confirming the only mucosal involvement. We performed an EMR using "cup and suction" method. After the procedure, the patient experienced an acute upper gastrointestinal bleeding from the ulcer bed requiring argon plasma coagulation. The histopathological examination confirmed an early cancer, without involvement of muscularis mucosae. The patient has had an uneventful evolution being well at six months after the procedure

Pediatric foreign-body (FB) ingestion is a common problem. Many of these FBs are sharp objects such as needles, toothpicks and safety pins (SP). This report reviews the management of SP ingestion in children. During a 16-year period, we recorded 49 pediatric cases of witnessed SP ingestion. In all children, SPs were used to attach the blue beads to the child's suits with the belief of averting the evil eye. The mean age was 8 months ranging from 4 months to 2 years, and 30 patients were males and 19 were females. SPs were most commonly sited in esophagus (37%) and stomach (37%). In the remainder, the SPs have already reached the duodenum and intestine. In this series, 20 (41%) children passed SPs spontaneously, 14 (28.5%) required endoscopic removal and 15 (30.5%) underwent surgery. The outcome of all patients was uneventful. All of the esophageal SPs require endoscopic intervention, however, after passing into stomach the patients can be observed with keeping the surgical intervention in mind if the SP displays a fixed position for more than three days.

Use of the Uro Dyna-CT in endourology - the new frontier.

We describe the use of the Uro Dyna-CT, an imaging system used in the operating room that produces real-time three-dimensional (3D) imaging and cross-sectional image reconstructions similar to an intraoperative computerized tomography, during a percutaneous nephrolithotomy and a contralateral flexible ureteroscopy in a complete supine position. A 65 year-old female patient had an incomplete calyceal staghorn stone in the right kidney and a 10mm in the left one. The procedure was uneventful and the intraoperative use of the Uro Dyna-CT identified 2 residual stones that were not found by digital fluoroscopy and flexible nephroscopy at the end of surgery, helping us to render the patient stone-free in one procedure, which was confirmed by a postoperative CT scan. Prospective studies will define the real role of the Uro Dyna-CT for endourological procedures, but its use seems to be a very promising tool for improving stone free rates and decreasing auxiliary procedures, especially for complex cases.

We report a case of huge colon cancer accompanied with severe hypoproteinemia. A7 4-year-old woman was referred to our hospital because of abdominal fullness. Blood examinations revealed anemia(hemoglobin 8.8 g/dL)and sever hypopro- teinemia(total protein 4.5 g/dL, albumin 1.1 g/dL). Computed tomography examination of abdomen revealed ascites and large tumor(12.5×10.5 cm)at the right side colon. By further examinations ascending colon cancer without distant metastasis was diagnosed, then we performed right hemicolectomy and primary intestinal anastomosis by open surgery. Ahuge type 1 tumor(18×12 cm)was observed in the excised specimen, which invaded to terminal ileum directly. The tumor was diagnosed moderately differentiated adenocarcinoma without lymph node metastasis(pT3N0M0, fStage II ). Postoperative course was uneventful and serum protein concentration recovered gradually to normal range. Protein leakage from the tumor cannot be proved by this case, so we can't diagnose as protein-losing enteropathy, but we strongly doubt this etiology from postoperative course in this case.

A 63-year-old Japanese woman with a history of pemphigus was referred to us for abnormal findings of dynamic abdominal CT where three aneurysms of splenic artery and pancreaticoduodenal artery, celiac axis compression, and gall stone. Superior mesenteric artery supplied hepatic arterial flow via pancreaticoduodenal artery. Avoiding transarterial embolization to prompt arterial ischemia of liver/pancreas head/duodenum, she laparotomically underwent cholecystectomy, splenectomy, transection of median arcurate ligament, and ligation of splenic and inferior pancreaticoduodenal artery all at once. Postoperative course was uneventful except drainage of abdominal abscess, and she remained well without aneurysm recurring 40 months post. Important point of treatment for pancreaticoduodenal artery aneurysm associated with celiac artery occlusion/stenosis is both preventive solutions for rupture of aneurysm and hepatic/duodenal/pancreatic arterial ischemia. Remaining main arterial supply for the liver via pancreaticoduodenal artery from superior mesenteric artery would prompt recurrent aneurysm of pancreaticoduodenal artery. When a clinician encounters a case of pancreatic aneurysm associated with celiac axis occlusion, the case should be treated using with multimodality such as interventional radiology, and vascular surgery.

Neoplastic sigmoid-uterine fistula is an extremely rare condition because the uterus is a thick and muscular organ. A 74-year-old woman was admitted to the First Aid Station suffering from abdominal pain and foul smelling vaginal discharge. Gynaecological examination showed fecal drainage from the cervical orifice, while the uterus was regular in size but very firm and painful. Ovaries and fallopian tubes were not palpable owing to abdominal tenderness. Ultrasounds reveled inhomogeneous thickening of uterine cavity, without detecting fistula. Contrast Medium CT (CMCT) showed Douglas’ recto-uterine pouch occluded. The sigmoid wall was very thin exception a site where a fistula was suspected. At the surgery severe adhesions of the sigma-rectum with the posterior uterine wall were observed. After adhesiolysis, 18 cm colon-sigma-rectum was removed. Total hysterectomy with salpingooophorectomy was performed. Lymphadenectomy ended the procedure. Anatomical specimen confirmed sigmoid-uterine fistula. At histology a mildly differentiated adenocarcinoma of sigma-rectum was shown. Postoperative course was uneventful. Such a case of neoplastic sigmoid-uterine fistula has not been reported so far.

A 42-year-old woman with hysteromyoma underwent total abdominal hysterectomy under general and epidural anesthesia. Three years before, she had undergone resection of lipoma on her left shoulder under local anesthesia uneventfully. She had no previous history of hypersensitivity. General anesthesia was induced by intravenous injection of fentanyl, propofol, and vecuronium followed by inhalation of nitrous oxide, oxygen, and sevoflurane. Lidocaine and fentanyl were injected through a lumbar epidural catheter. After the start of open laparotomy, there was a sudden onset of hypotension. Administrations of ephedrine and phenylephrine, and volume loading were ineffective. Moreover, she showed profound hypotension, tachycardia, oxygen desaturation, decreased endtidal carbon dioxide and increased airway pressure. She broke out in a sweat with flushing on her chest and upper extremities. Therefore, we interrupted the surgery, checked her arterial blood gas analysis, performed echocardiography, and inserted a pulmonary artery catheter. We made a diagnosis of anaphylactic shock and administered methylprednisolone, albumin, epinephrine, norepinephrine, and dopamine to treat the circulatory collapse. The gynecologists changed their surgical gloves from a powdered-latex type to a powder-free latex type, and the surgery was resumed. She responded well to appropriate emergent therapy and all vasopressor drugs were gradually decreased and eventually stopped. After the end of the surgery, she recovered completely from the signs and symptoms of shock. Later, we found a high level of plasma latex protein-specific IgE antibody and confirmed the events as anaphylactic shock due to latex. We assumed that the anaphylactic shock was powder-induced latex allergy following use of powdered latex gloves in this case. Latex allergy should be suspected if an anaphylactic reaction or shock accompanied by circulatory collapse, respiratory failure, and skin symptoms of unknown origin occurs during surgery. As women more often come into contact with household articles containing latex, we suspect that women are prone to developing sensitivity towards latex. We recommend that powder-free or latex-free surgical gloves should be available not only for patients with a high risk of developing latex allergy, but also for patients indicated for gynecological open laparotomy.

The aim of the study was to clinically and histologically evaluate the healing of human intrabony defects treated with open flap surgery (OFD) and application of a new, resorbable, fully synthetic, unsintered, nanocrystalline, phase-pure hydroxyapatite (nano-HA). Six patients, each of them displaying very advanced intrabony defects around teeth scheduled for extraction due to advanced chronic periodontitis and further prosthodontic considerations, were included in the study. Following local anaesthesia, mucoperiosteal flaps were reflected; the granulation tissue was removed, and the roots were meticulously debrided by hand and ultrasonic instruments. A notch was placed at the most apical extent of the calculus present on the root surface or at the most apical part of the defect (if no calculus was present) in order to serve as a reference for the histological evaluation. Following defect fill with nano-HA, the flaps were sutured by means of mattress sutures to allow primary intention healing. At 7 months after regenerative surgery, the teeth were extracted together with some of their surrounding soft and hard tissues and processed for histological analysis. The postoperative healing was uneventful in all cases. At 7 months following surgery, mean PPD reduction and mean CAL gain measured 4.0 ± 0.8 and 2.5 ± 0.8 mm, respectively. The histological analysis revealed a healing predominantly characterized by epithelial downgrowth. Limited formation of new cementum with inserting connective tissue fibers and bone regeneration occurred in three out of the six biopsies (i.e. 0-0.86 and 0-1.33 mm, respectively). Complete resorption of the nano-HA was found in four out of the six biopsies. A few remnants of the graft particles (either surrounded by newly formed mineralized tissue or encapsulated in connective tissue) were found in two out of the six biopsies. Within their limits, the present results indicate that nano-HA has limited potential to promote periodontal regeneration in human intrabony defects. The clinical outcomes obtained following surgery with OFD + nano-HA may not reflect true periodontal regeneration.

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 after cataract surgery, when topical NSAIDs are applied.

According to the classification given by Crawford et al. type III thoracoabdominal aortic aneurysm (TAAA) is dilatation of the aorta from the level of the rib 6 to the separation of the aorta below the renal arteries, capturing all the visceral branch of aorta. Visceral hybrid reconstruction of TAAA is a procedure developed in recent years in the world, which involves a combination of conventional, open and endovascular aortic reconstruction surgery at the level of separation of the left subclavian artery to the level of visceral branches of aorta. We presented a 75-years-old man, with elective visceral hybrid reconstruc tion of type III TAAA. Computerized scanning (CT) angiography of the patient showed type III TAAA with the maximum transverse diameter of aneurysm of 92 mm. Aneurysm started at the level of the sixth rib, and the end of the aneurysm was 1 cm distal to the level of renal arteries. Aneurysm compressed the esophagus, causing the patient difficulty in swallowing act, especially solid food, and frequent back pain. From the other comorbidity, the patient had been treated for a long time, due to chronic obstructive pulmonary disease and hypertension. In general endotracheal anesthesia with epidural analgesia, the patient underwent visceral hybrid reconstruction of TAAA, which combines classic, open vascular surgery and endovascular procedures. Classic vascular surgery is visceral reconstruction using by-pass procedure from the distal, normal aorta to all visceral branches: celiac trunk, superior mesenteric artery and both renal arteries, with ligature of all arteries very close to the aorta. After that, by synchronous endovascular technique a complete aneurysmal exclusion of thoracoabdominal aneurysm with thoracic stent-graft was performed. The postoperative course was conducted properly and the patient left the Clinic for Vascular Surgery on postoperative day 21. Control CT, performed 3 months after the surgery showed that the patient's vascular status was uneventful with functional visceral by-pass and with good position of a stent-graft without a significant endoleak. Visceral hybrid reconstruction represents a complementary surgical technique to that with open reconstruction of TAAA. This approach is far less traumatic to a patient, and is especially important in patients with lot of comorbidities, because there is no need for thoracotomy, and ischemic-reperfusion injury of the body is reduced to a minimum.

We performed venous shunt procedure in the reconstruction of the esophagus after esophagectomy using the gastric tube in two cases of esophageal cancer with portal hypertension due to liver cirrhosis. In both cases, the short-term postoperative course was uneventful, without congestion in the gastric tube. In Case 1 where the short gastric vein had been used as the shunt vein, the long-term postoperative course was also uneventful, without hepatic encephalopathy or hemorrhage from deterioration of the varices of the gastric tube. However, in Case 2 where the left gastroepiploic vein had been used, hepatic encephalopathy developed due to excessive shunt flow. These results suggested that appropriate shunt flow could be expected by using short gastric vein.

[Pseudophakic cystoid macular oedema].

PubMed

Bertelmann, T; Witteborn, M; Mennel, S

2012-08-01

Pseudophakic cystoid macular oedema is still a relevant clinical disease entity although major progress in modern cataract surgery has been made within the last decades. The relevance is attributed to the large number of cases that are performed each year. Even after uneventful surgery, a pseudophakic cystoid macular oedema can develop and may lead to severe and lasting visual impairments. In respect to the pathophysiology, four consecutive steps have to be considered: (i) surgical procedure-related induction and release of various inflammation mediators into the anterior chamber; (ii) removal of the physiological lens barrier between the anterior and posterior segments of the eye, leading consecutively to an increase in diffusion rate in either direction; (iii) local action of the inflammation mediators towards the macular area; and (iv) increased vitreoretinal traction due to the anteriorly oriented drive of the vitreous. To prevent the development of a pseudophakic cystoid macular oedema, systemic and ocular pathologies should be treated consequently prior to surgery. Furthermore, an individual risk profile of each patient needs to be evaluated to define the best pre- and postsurgical medical treatment. A less traumatic surgical approach can help to prevent macular oedema development additionally. The diagnosis is made by performing biomicroscopy, fluorescence angiography and optical coherence tomography as well as by evaluating the patients' major complaints. Standard operation procedures or recommended guidelines by the specialised eye associations to prevent and treat pseudophakic cystoid macular oedema are not available up to date. A synopsis of recommendations in the literature suggests a step-wise treatment regimen, including topical medical treatment on the one hand and a surgical approach on the other hand as well as a combination of both, if needed. Topical medical treatment options include the use of non-steroidal, corticosteroid and/or carbonic anhydrase inhibitor eye drops. Surgical interventions include pars plana vitrectomy. © Georg Thieme Verlag KG Stuttgart · New York.

Randomized, controlled clinical trial to evaluate a xenogeneic collagen matrix as an alternative to free gingival grafting for oral soft tissue augmentation.

PubMed

McGuire, Michael K; Scheyer, E Todd

2014-10-01

The standard of care for increasing keratinized tissue (KT) and vestibular area is an autogenous free gingival graft (FGG) and vestibuloplasty; however, there is morbidity associated with the harvest of autogenous tissue, and supply is limited. The purpose of this study is to determine if a xenogeneic collagen matrix (CM) might be as effective as FGG. This study is a single-masked, randomized, controlled, split-mouth study of 30 patients with insufficient zones of KT (<2 mm). It uses a within-patient treatment-comparison design to establish non-inferiority of the test (CM) versus control (FGG) therapy. The primary efficacy endpoint was change in KT width (∆KT) from surgery to 6 months post-surgery. Secondary endpoints included traditional periodontal measures, such as clinical attachment level, recession, and bleeding on probing. Patient-reported pain, discomfort, and esthetic satisfaction were also recorded. Biopsies were obtained at 6 months. Surgery and postoperative sequelae were uneventful, with normal healing observed at both test and control sites. The primary outcome, ∆KT width at 6 months, did not establish non-inferiority of CM compared to FGG (P = 0.9992), with the FGG sites averaging 1.5 mm more KT width than CM sites. However, the amount of new KT generated for both therapies averaged ≥2 mm. Secondary outcomes were not significantly different between test and control sites. All site biopsies appeared as normal mucoperiosteum with keratinized epithelium. CM sites achieved better texture and color matches, and more than two-thirds of patients preferred the appearance of their CM sites. With the proviso of sufficient KT (≈2 mm in width) and study goals of lower morbidity, unlimited supply, and patient satisfaction, CM appears to be a suitable substitute for FGG in vestibuloplasty procedures designed to increase KT around teeth.

Selective excision of cerebral metastases from the precentral gyrus

PubMed Central

Kellogg, Robert G.; Munoz, Lorenzo F.

2013-01-01

Background: The surgical management of cerebral metastases to the eloquent cortex is a controversial topic. Precentral gyrus lesions are often treated with whole brain radiation therapy (WBRT) or stereotactic radiosurgery (SRS) because of the concern for causing new or worsened postoperative neurological deficits. However, there is evidence in the literature that radiation therapy carries significant risk of complication. We present a series of patients who were symptomatic from a precentral gyrus metastasis and underwent surgical excision. Methods: During a 2-year period from 2010 to 2012, 17 consecutive patients harboring a cerebral metastasis within the precentral gyrus underwent microsurgical resection. All patients were discussed at a multi-disciplinary tumor board. The prerequisite for neurosurgical treatment was stable systemic disease and life expectancy greater than 6 months as determined by the patient's oncologist. Patients also were required to harbor a symptomatic lesion within the motor cortex, defined as the precentral gyrus. Results: We present the 3-month neurological outcome for this group of patients. Surgery was uneventful and without any severe perioperative complications in all 17 patients. At 3 month follow up, symptoms had improved or been stabilized in 94.1% of patients and were worsened in 5.9%. Conclusion: Our results have shown that surgery for cerebral metastases in the precentral gyrus can be done safely and improve or stabilize the neurological function of most patients. Microsurgical resection of precentral gyrus metastases should be a treatment option for patients with single or multiple lesions who present a focal neurologic deficit. This can be performed safely and without intraoperative cortical mapping. PMID:23776752

Pseudotumor Caused by Titanium Particles From a Total Hip Prosthesis.

A 77-year-old woman underwent metal-on-polyethylene total hip arthroplasty for osteoarthritis of the right hip at another institution. During surgery, the greater trochanter was broken and internal fixation was performed with a trochanteric cable grip reattachment. Although postoperative recovery was uneventful, approximately 6 years later, the patient had severe right hip pain with apparent swelling, and she was referred to the authors' institution. Plain radiographs showed evidence of severe osteolysis in the proximal femur and cable breakage; however, preoperative aspiration culture findings were negative for bacterial growth. Magnetic resonance imaging showed a well-circumscribed mass, presumed to be a pseudotumor. Serum cobalt and chromium levels were within normal limits, and the serum titanium level was high. During surgery, the mass was excised and removal of the cable system revealed a sharp deficit in the bare femoral stem. Gross surgical findings showed no obvious evidence of infection and no corrosion at the head-neck junction; therefore, all components were retained besides the cable system, which resulted in clinical recovery. All of the cultures from specimens were negative for bacterial growth, and histologic findings were compatible with a pseudotumor, such as histiocytes containing metal particles, abundant plasma cells, and CD8-positive cells. Quantitative analysis by inductively coupled plasma atomic emission spectrometry showed that the main source of metal debris in the pseudotumor was the femoral stem, which was made of titanium alloy, not the broken cable, which was made of cobalt-chromium alloy. The findings suggest that titanium particles can form symptomatic solid pseudotumors. Copyright 2016, SLACK Incorporated.

Intrauterine intestinal volvulus is an extremely rare case of acute congenital intestinal obstruction. The diagnosis is usually possible in the third trimester of a pregnancy. Fetal midgut volvulus is most likely to be recognized by observing a typical clockwise whirlpool sign during color Doppler investigation. Multiple dilated intestinal loops with fluid levels are usually visible during the antenatal ultrasound as well. Physical and radiographic findings in the newborn indicate intestinal obstruction and an emergency surgery is required. The authors describe intrauterine volvulus in 3 female newborns in which surgical treatment was individualized. The decision about primary or delayed anastomosis after resection of the gangrenous part of the small bowel was made at the time of the surgery and depended on the general condition of the newborn, as well as presence or absence of meconium peritonitis. Double loop jejunostomy was performed in case of two newborns, followed by a delayed end-to-end anastomosis. In case of the third newborn, good blood supply of the small intestine after untwisting and 0.25% lignocaine injections into mesentery led to the assumption that the torsion was not complete and ischemia was reversible. In the two cases of incomplete rotation the cecum was sutured to the left abdominal wall to prevent further twisting. The postoperative course was uneventful and oral alimentation caused no problems. Physical development of all these children has been normal (current age: 1-2 years) and the parents have not observed any disorders or problems regarding passage of food through the alimentary canal. Prompt antenatal diagnosis of this surgical emergency and adequate choice of intervention may greatly reduce mortality due to intrauterine volvulus.

We report our first simultaneous bilateral robot assisted partial nephrectomy (RAPN) in order to show and critically discuss the feasibility of this procedure. Materials and methods A 69-year-old male patient visited our department due to incidental finding of bilateral mesorenal small masses (2.5 cm on the right and 3.5 cm on the left) suspicious for malignancy. We started from the right side with patient in flank position. Port placement: 12-mm periumbilical camera port, two 8-mm robotic ports in wide ''V''configuration, additional 12 mm assistant port on the midline between the umbilicus and symphysis pubis. A right unclamping RAPN with sliding clip renorrhaphy was performed. The trocars were removed and the robot undocked. Without interrupting the anesthesiological procedures, the patient was reported in supine position and, after 180 degrees rotation of the surgical bed, was newly placed in contralateral flank position. Using both the previous periumbilical and midline ports, two other 8-mm robotic trocars were placed. The robot was then redocked and RAPN was also performed on the left side using the same previously reported technique. Results Total time: 285 min. Estimated blood losses: 150 cc. Postoperative period: uneventful. Pathological examination: bilateral renal cell carcinoma, negative surgical margins. Conclusions Our experience was encouraging and confirmed the feasibility and safety of this procedure. The planning of our technique was time and cost effective with cosmetic benefit for the patient. However, we think that an appropriate selection of the patients and a skill in robotic renal surgery are advisable before approaching this type of surgery.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer, whereas lymphoma is the sixth leading cause of cancer death, 90% of which corresponds to non-Hodgkin's lymphoma (NHL). The association of these two primary tumors, a solid tumor with an hematological malignancy, is very uncommon. We report the case of a 47-year-old man who presented with abdominal pain, a right upper quadrant mass and 12 kg of weight loss in 9 months. The computed tomography (CT) showed a large intra-abdominal mass and a wall thickening at the rectosigmoid junction. A colonoscopic biopsy confirmed a colorectal adenocarcinoma and a laparoscopic biopsy of the intraabdominal mass confirmed a diffuse large B-cell NHL. After multidisciplinary discussion it was decided to treat first the NHL with 3 cycles of R-CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisone). The patient experienced a good response with a 70% decrease in the intraabdominal mass and a negative PET/CT. Four months after diagnosis an anterior rectal resection was performed. The patient recovered uneventfully and was discharged 5 days after surgery. The patient finally died 20 months after surgery due to disease progression. The association of CRC and NHL is an extremely rare scenario that represents a great multidisciplinary challenge with respect to treatment due to the scarce literature found on this topic. When CRC and NHL are present, all the different disease patterns must be considered in a multidisciplinary and patient-oriented fashion, in order to decide the best therapeutic strategy for each individual.

Altered healing following mucogingival surgery in a patient with Crohn's disease: a literature review and case report.

PubMed

Andersen, Kari M; Selvig, Knut A; Leknes, Knut N

2003-04-01

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.

Introduction Catamenial pneumothorax (CP) is a spontaneous recurrent pneumothorax occurring in women in reproductive age. The etiology of CP has been associated with thoracic endometriosis and is its most common presentation. Presentation of case A case of right catamenial pneumothorax in a 38 year old woman is presented in which three episodes of CP occurred within 72 h of menses in a 6 month period. The patient underwent videothoracoscopy that revealed a solitary localization of diaphragmatic endometriosis. After surgical pleurodesis and based on final pathology of resected lesion, hormonal treatment was started. The outcome was uneventful and the patients is symptom-free at 6 months. Discussion Catamenial pneumothorax (CP) is a rare clinical entity characterized by lung collapse during menstruation, believed to be secondary to pleural endometriosis. Nearly all catamenial pneumothorax occur on the right side as pleural lesions are almost exclusively right-sided. Diagnostic imaging is based on high resolution computed tomography (HRCT) and, preferably, magnetic resonance imaging (MRI) since it is able to detect the blood products in the endometrial deposits. However the lack of macroscopic findings at surgery makes this condition still under-diagnosed. Based on the solitary diaphragmatic localization of endometriosis in our case we preferred to limit surgery to videothoracoscopic pleurodesis and start hormonal treatment with successful outcome. Conclusion Catamenial pneumothorax is the most common presentation of thoracic endometriosis syndrome and should always be suspected in women in childbearing age. Treatment option are still debated but best results are achieved by videothoracoscopic pleurodesis combined with hormonal therapy. PMID:25981153

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.

2012-01-01

Background: Laparoscopy is one of the most common surgical procedures and is the procedure of choice for most of the elective abdominal surgeries performed preferably under endotracheal general anesthesia. Technical advances in the field of laparoscopy have helped to reduce surgical trauma and discomfort, reduce anesthetic requirement resulting in shortened hospital stay. Recently, regional anaesthetic techniques have been found beneficial, especially in patients at a high risk to receive general anesthesia. Herewith we present a case series of laparoscopic appendectomy in eight American Society of Anaesthesiologists (ASA) I and II patients performed under spinal-epidural anaesthesia. Methods: Eight ASA Grade I and II adult patients undergoing elective Laparoscopic appendectomy received Combined Spinal Epidural Anaesthesia. Spinal Anaesthesia was performed at L2-L3 interspace using 2 ml of 0.5% (10 mg) hyperbaric Bupivacaine mixed with 0.5ml (25 micrograms) of Fentanyl. Epidural catheter was inserted at T10-T11 interspace for inadequate spinal anaesthesia and postoperative pain relief. Perioperative events and operative difficulty were studied. Systemic drugs were administered if patients complained of shoulder pain, abdominal discomfort, nausea or hypotension. Results: Spinal anaesthesia was adequate for surgery with no operative difficulty in all the patients. Intraoperatively, two patients experienced right shoulder pain and received Fentanyl, one patient was given Midazolam for anxiety and two were given Ephedrine for hypotension. The postoperative period was uneventful. Conclusion: Spinal anaesthesia with Hyperbaric Bupivacaine and Fentanyl is adequate and safe for elective laparoscopic appendectomy in healthy patients but careful evaluation of the method is needed particularly in compromised cardio respiratory conditions.

Despite advances in reconstruction techniques, pressure sores continue to present a challenge to the plastic surgeon. The parasacral perforator flap is a reliable flap that preserves the entire contralateral side as a future donor site. On the ipsilateral side, the gluteal muscle itself is preserved and all flaps based on the inferior gluteal artery are still possible. We present our experience of using parasacral perforator flaps in reconstructing sacral defects. Between August 2004 and January 2013, 19 patients with sacral defects were included in this study. All the patients had undergone surgical reconstruction of sacral defects with a parasacral perforator flap. The patients' sex, age, cause of sacral defect, flap size, flap type, numbers of perforators used, rotation angle, postoperative complications, and hospital stay were recorded. There were 19 parasacral perforator flaps in this series. All flaps survived uneventfully except for 1 parasacral perforator flap, which failed because of methicillin-resistant Staphylococcus aureus infection. The overall flap survival rate was 95% (18/19). The mean follow-up period was 17.3 months (range, 2-24 months). The average length of hospital stay was 20.7 days (range, 9-48 days). No flap surgery-related mortality was found. Also, there was no recurrence of sacral pressure sores or infected pilonidal cysts during the follow-up period. Perforator-based flaps have become popular in modern reconstructive surgery because of low donor-site morbidity and good preservation of muscle. Parasacral perforator flaps are durable and reliable in reconstructing sacral defects. We recommend the parasacral perforator flap as a good choice for reconstructing sacral defects.

Acute and chronic fluid misdirection syndrome: pathophysiology and treatment.

Grzybowski, Andrzej; Kanclerz, Piotr

2018-01-01

To summarize our current understanding of the specific pathogenic mechanisms of the fluid misdirection syndrome and possible treatment methods. We used the PubMed web platform to find relevant studies using the following keywords: infusion misdirection syndrome, aqueous misdirection syndrome, ciliary block, ciliovitreal block, capsular block, intraoperative fluid misdirection, subcapsular fluid entrapment, acute intraoperative rock-hard eye syndrome, positive vitreous pressure glaucoma, and malignant glaucoma. Other publications were also considered as a potential source of information when referenced in relevant articles. We collected and analyzed 55 articles dated from 1951 to 2016. Acute intraoperative rock-hard eye syndrome is characterized by a very shallow anterior chamber with the absence of suprachoroidal effusion or hemorrhage and no noticeable pathology of the iris-lens diaphragm. It usually occurs during uneventful phacoemulsification, particularly in hyperopic eyes. The pathophysiology of acute fluid misdirection syndrome is based on inappropriate movement of balanced salt solution via the zonular fibers. This syndrome has also been described as occurring from hours to months, or years, after the initial surgery. The pathophysiology of malignant glaucoma is based on similar mechanisms of cilio-lenticular block of aqueous flow leading to the misdirection of aqueous posteriorly into or besides the vitreous gel. Faced with these situations, vitreous decompression is required, preferably with hyaloido-capsulo-iridectomy. In phakic eyes, concomitant cataract extraction would be desirable. We believe both of these clinical conditions should be considered as one syndrome. We suggest the term acute fluid misdirection syndrome for the cascade of events during phacoemulsification surgery. Chronic fluid misdirection syndrome better describes the nature of malignant glaucoma.

We present a case of a 51-year-old male patient hospitalized due to acute coronary syndrome requiring stent implantation to the left main stem. Double antiplatelet therapy was commenced. After 2-3 days, the patient presented with high fever, dyspnea on exertion, pain in the chest, myalgia, and general weakness. Transthoracic (TTE) and transesophageal (TEE) echocardiography revealed abnormal, turbulent flow across the aortic prosthesis, which was probably caused by the presence of a pathological smooth and mobile structure (10 × 9 × 5 mm) in front of the aortic annulus. Blood cultures were positive and staphylococcal prosthetic valve endocarditis (PVE) was diagnosed. Despite antibiotic treatment, the patient's condition deteriorated, and he was referred for prosthesis reimplantation. After being transferred to the Cardiac Surgery Clinic, he presented with nausea, vomiting, and abdominal pain. The results of imaging examinations suggested spleen hematoma. The patient underwent an urgent splenectomy. Histopathological examination revealed a spleen infarction consequent to an embolic event and subscapular hematoma. On the 10(th) day after the laparotomy, cardiac surgery was performed. No large vegetations were found on the aortic prosthesis. The mechanical valve, implanted 20 years earlier, was functioning properly; it was intact and well healed. Several fragments of a thrombus and fibrous tissue, resembling a pannus and covered with minor calcifications, were removed from the ventricular surface of the discs. A decision was reached to leave the aortic prosthesis in situ. The valvular material culture revealed the presence of Streptococcus anginosus, and the antibiotic scheme was modified. The postoperative period was uneventful.

Marginal ulcer is not infrequent after laparoscopic Roux-en-Y gastric bypass and could result in undesirable complications, such as intractability, bleeding, or perforation. Those patients who failed medical therapy, regarded as refractory marginal ulcers, may be considered as candidates for revisional surgery. Herein, we make a video presentation of a laparoscopic revisional procedure for refractory marginal ulcer. A 29-year-old morbidly obese woman (initial body mass index 37.1 kg/m(2)), a non-smoker, presented with persistent epigastric pain 3 months after initial laparoscopic Roux-en-Y gastric bypass at another institution. After an exhaustive work-up there, only the gastroendoscopy revealed a marginal ulcer and she underwent medical treatment (proton pump inhibitor and sucralfate) for 3 months, but the patient's symptom aggravated and the serial gastroendoscopies still confirmed the marginal ulcer without obvious resolution after a total of 4 months proton pump inhibitor therapy, suggesting failure of medical treatment and intractability. Laparoscopic revisional procedure with totally hand-sewn gastrojejunostomy and vagotomy was performed to relieve her intractable condition. The procedure took 130 min, without any intra-operative complications. Blood loss was 80 mL. The patient had an uneventful postoperative course, and the postoperative hospital stay was 3 days. She was relieved of her symptoms after this revisional surgery, and a subsequent gastroendoscopy 15 months later showed no marginal ulcers. Though long-term follow-up is needed to draw a definite conclusion, totally hand-sewn gastrojejunostomy and vagotomy remains a practicable revisional procedure to relieve refractory marginal ulcers.

Surgery via natural orifices in human beings: yesterday, today, tomorrow.

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

Laser welding of biological tissue: experimental studies in ophthalmology

NASA Astrophysics Data System (ADS)

Pini, Roberto; Rossi, Francesca; Menabuoni, Luca

2006-04-01

In this paper we present an original approach to laser welding of ocular media. Attention is focused on laser welding of the cornea and lens capsule. The process is based on the interaction of near infrared diode laser radiation (at 810 nm) with tissue that was previously stained with an Indocyanine Green solution in sterile water. The topical application of the chromophore makes possible a selective heating of the tissue, which results in a homogenous welding effect with low thermal damage to the surrounding tissue. Experimental tests were performed ex vivo on both capsule and cornea, and in vivo (rabbits) only on the cornea, in order to characterize the process as a whole. Spectrophotometric, biomechanical, and thermal measurements were carried out in order to study the laser-tissue interaction, while morphological, histological and auto-florescence microscopy analyses made during a follow-up study provided information on the healing process in welded rabbit corneas. The welding procedure was set up according to the type of tissue, with the staining procedure and irradiation conditions being optimized in each case. Our test indicated that: 1) laser welding of corneal wounds, which is a non contact technique performed at low continuous wave laser power (12 W/cm2), can be proposed as a support to or substitute for the standard suturing technique in cataract surgery and in penetrating keratoplasty (in corneal transplants); 2) laser welding of the lens capsule requires a "contact irradiating technique" in order to be efficiently performed, since the tissue is in underwater conditions, with single spot pulses of about 100 J/cm2 fluence and pulse duration around 100 ms. In the latter case, laser welding was proposed as a tool for assisting closure of the lens capsule after the lens refilling procedure (Phaco-ersatz), or for repairing capsular breaks induced by accidental traumas or produced intraoperatively.

Transcatheter mitral valve implantation for mitral valve regurgitation is in the very early phase of development because of challenging anatomy and device dimensions. We describe the procedure of a transfemoral-transseptal implantation of the second-generation CardiAQ mitral valve bioprosthesis and 30-day follow-up. The procedure was performed percutaneously, without any left extracorporeal circulatory support. The patient had severe mitral regurgitation with severely depressed ventricular function and other comorbidities. The patient was deemed extreme high risk for conventional cardiac surgery by a multidisciplinary team. The main procedural steps were the creation of an arteriovenous loop with an exchange nitinol wire, and the use of a customised "steerable snare system" to facilitate the catheter delivery system into the mitral annulus. Transoesophageal echocardiography and fluoroscopy were utilised for device positioning and deployment. The mitral valve prosthesis was implanted with mild mitral regurgitation. The postoperative course was uneventful and at 30-day follow-up the patient is in NYHA Class I, with good function of the mitral valve bioprosthesis. This procedure shows that percutaneous transfemoral transcatheter mitral valve implantation is feasible, safe and successful. Further experience is needed to render this procedure clinically available.

Interrupting the afferent signals that travel through the splanchnic nerves by multiportal thoracoscopic splanchnotomy can offer effective palliation in chronic pancreatitis. However, obtained results weaken after time, possibly necessitating repeat procedures. Given the palliative nature of this procedure, potential for iatrogenic damage should be kept at a minimum. So, in order to minimize invasiveness while optimizing repeatability, we sought to create an easily reproducible single-access port operative strategy. Four patients suffering from intractable pain due to chronic pancreatitis for >10 years (12.8 ± 5.9) underwent a single-port unilateral R5-R11 splanchnotomy. Postoperative recovery was uneventful. No operative complications were observed. All 4 patients experienced excellent pain relief with a significant improvement of Visual Analogue Scale pain scores (8.8 ± 1.0 preoperatively to 3.0 ± 1.2 postoperatively, P = 0.003). We report the first series of single-port video-assisted thoracoscopic surgical (VATS) splanchnotomy for palliation of intractable pain due to chronic pancreatitis. From this small study, single-port VATS splanchnotomy seems to be a safe and effective alternative to multiportal or open procedures. © The Author 2016.

To report the surgical treatment of a pulmonary emphysematous cyst concurrent with primary pulmonary bronchoalveolar papillary carcinoma in a dog. Clinical case report. 12-year-old 6.4 kg spayed female Shih Tzu dog. The dog presented for surgical treatment of pulmonary emphysema. Radiography revealed that more than half of the left caudal lung lobe was enlarged and hyperlucent and computed tomography (CT) confirmed the presence of an emphysematous space. Thoracoscopic lung lobectomy was attempted but was converted to an intercostal thoracotomy due to poor visualization and pleural adhesions. A left caudal total lung lobectomy was performed using a self-cutting endoscopic stapler. The dog recovered uneventfully and a postoperative histopathologic diagnosis of pulmonary cystic bronchoalveolar papillary carcinoma was made. Re-evaluation using a CT scan with contrast study on postoperative days 27 and 177 revealed no evidence of residual, metastatic, or recurrent lesions. The dog has been doing well since surgery during the 11 month follow-up period. This case report suggests a potential relationship between pulmonary emphysematous diseases and primary lung tumors in dogs. © 2016 The American College of Veterinary Surgeons.

For the early diagnosis and therapy of peripheral thromboembolism (TE) as a complication of abdominal aortic repair (AAR), we developed and evaluated the usefulness of surgical drapes that permit observation of the lower extremities during AAR. Between January 2007 and June 2009, the handling, durability, and usefulness of new surgical drapes were evaluated during AAR in 157 patients with abdominal aortic aneurysms and 9 patients with peripheral arterial disease. The drapes are manufactured by Hogy Medical Co. Ltd. and made of a water-repellent, spun lace, non-woven fabric, including a transparent polyethylene film that covers the patients' legs. This transparent film enables inspection and palpation of the lower extremities during surgery for early diagnosis and therapy of peripheral TE. As a peripheral complication, 1 patient had right lower extremity TE. This was diagnosed immediately after anastomosis, thrombectomy was performed, and the remaining clinical course was uneventful. In all patients, the drapes permitted observation of the lower extremities , and the dorsal arteries were palpable. There were no problems with durability. New surgical drapes permit observation of the lower extremities during AAR for early diagnosis and treatment of peripheral TE.

Granulomatous lobular mastitis: A clinicopathological study of 112 cases.

We report 12 cases of granulomatous lobular mastitis occurring in young women, between ages 30 and 47 years, diagnosed at King Faisal Specialist Hospital and Research Centre (KFSH&RC) from 1987 to 1995. The disease was unilateral in 10 cases, while there was a history of involvement of the contralateral breast in two patients. At the time of diagnosis, two patients were lactating, two were pregnant, and two were pregnant and lactating. Histopathological examination in all cases revealed centrilobular granulomas and microabscess formation. Immunohistochemical staining in seven cases for T and B cell markers showed a predominance of T cells in the infiltrate in all cases. The treatment comprised surgical removal of the mass, debridement and antibiotics in some of the cases. In one patient referred from another institution, mastectomy had been performed on the basis of an erroneous histopathologic diagnosis of carcinoma. Preoperative diagnosis was carcinoma in seven cases and benign disease in the remaining five cases. Follow-up of the patients was uneventful in all cases. Granulomatous lobular mastitis is a rare inflammatory disease of the breast, which may clinically and pathologically mimic carcinoma, sometimes leading to misdiagnosis resulting in unnecessary surgery.

Hepatic angiomyolipoma is a rare benign mesenchymal tumor of the liver. Most multiple hepatic angiomyolipomas have appeared in patients with renal angiomyolipoma and tuberous sclerosis. A 38-year-old female patient without chronic hepatitis B or C was hospitalized because of epigastric fullness for 2 months. Radiologic studies showed a large solid tumor with a small daughter nodule in the right hepatic lobe. Upon intravenous bolus injection of contrast medium, both tumors showed weak heterogeneous enhancement in the delayed phase. Although hepatocellular carcinoma was suspected by the findings of computed tomography, percutaneous transhepatic ultrasound-guided biopsy was performed for the large tumor. The histopathology showed many mature fat cells intermingled with thick-walled blood vessels, and epithelioid cells with eosinophilic cytoplasm; the epithelioid cells stained positively for HMB-45 and smooth muscle actin. Angiomyolipoma of the liver was confirmed. The main tumor enlarged considerably during a follow-up period of 3 years. Surgical resection was performed due to persistent symptoms. She had an uneventful postoperative recovery and was well when followed up 10 months after surgery. We should be aware that a hepatic angiomyolipoma can change in size during its natural course, and this finding does not necessarily indicate malignancy.

Primary malignant melanoma in the tongue is very uncommon disease that is considered low in comparison to cutaneous melanoma. In this report, the authors described a case of the hemitongue reconstruction with fasciocutaneous free flap on the patient who suffered from the malignant melanoma primarily originating from the base of the tongue that was treated with surgery and radiotherapy but developed a lung metastasis. A 76-year-old man was referred to the otorhinolaryngology clinic after complaining of a painful mass present for 3 months on the right side of the tongue. A punch biopsy was revealed atypical cells with pigmentation that is consistent with malignant melanoma. After wide excision and bilateral neck dissection performed, hemipartial tongue reconstruction was done using a radial forearm free flap. The patient had an uneventful recovery and received a course of radiotherapy along with follow-up examinations for 3 years. The authors report this rare patient for providing the other surgeons with the useful information regarding the management of the malignant melanoma on the tongue with free flap reconstruction which turned out to be successful in loco-regional control.

Colorectal decompression with a catheter was performed for evacuation of stool before definitive surgery in two patients with a persistent cloaca. Two newborn female infants with persistent cloaca received placement of a silicone balloon-tipped catheter in the rectum via the cloacal orifice under fluoroscopic guidance at the time of diagnosis. The length of the cloaca was 2 and 1.5 cm, respectively. The diameter of the catheter was matched to the patients' rectal size and the open end was wrapped in a diaper to allow continuous drainage of stool. The infants underwent bowel irrigation with warm saline thrice a day, at home. Total urogenital mobilization was carried out in the infants at the age of 7 and 8 months, respectively. Both infants had no abdominal distension, colorectal dilatation, or urinary tract infection while the catheter was in situ. The postoperative course was uneventful, except for minimal wound dehiscence in one patient. At present, both infants can void spontaneously without any urological problems. In infants with a persistent cloaca less than 3 cm long and normal urinary tract function, adequate evacuation of stool may be achieved by colorectal decompression with a catheter, thus avoiding the need for a colostomy.

To report a technique for endoscopic cystoventriculostomy guided by preoperative navigated transcranial magnetic stimulation (nTMS) and tractography in a patient with a large speech eloquent arachnoid cyst. A 74-year old woman presented with a seizure and subsequent persistent anomic aphasia from a progressive left-sided parietal arachnoid cyst. An endoscopic cystoventriculostomy and endoscope-assisted ventricle catheter placement were performed. Surgery was guided by preoperative nTMS and tractography to avoid eloquent language, motor, and visual pathways. Preoperative nTMS motor and language mapping were used to guide tractography of motor and language white matter tracts. The ideal locations of entry point and cystoventriculostomy as well as trajectory for stent-placement were determined preoperatively with a pseudo-3-dimensional model visualizing eloquent language, motor, and visual cortical and subcortical information. The early postoperative course was uneventful. At her 3-month follow-up visit, her language impairments had completely recovered. Additionally, magnetic resonance imaging demonstrated complete collapse of the arachnoid cyst. The combination of nTMS and tractography supports the identification of a safe trajectory for cystoventriculostomy in eloquent arachnoid cysts. Copyright © 2017 Elsevier Inc. All rights reserved.

Neuromuscular signs associated with acute hypophosphatemia in a dog.

Claus, Kimberly N; Day, Thomas K; Wolf, Christina

2015-01-01

The purpose of this report was to describe the successful recognition and management of neuromuscular dysfunction secondary to severe, acute hypophosphatemia in an adult dog with a 2 day history of vomiting, anorexia, and abdominal pain. Radiographs were suggestive of a foreign body obstruction, and surgery was recommended. Resection and anastomosis of the distal duodenum and proximal jejunum was performed. The dog recovered uneventfully, but approximately 36 hr postoperatively, he was found to have significant weakness and muscle tremors that were accompanied by hyperthermia. The only significant abnormality on a serum biochemical profile was a phosphorous level of 0.26 mmol/L. Within 6 hr of initiating phosphorous supplementation, the patient fully recovered and had no residual signs of neuromuscular dysfunction. Signs of neurologic dysfunction secondary to hypophosphatemia are commonly recognized in human patients. Reports of patients with severe muscle weakness, some of which necessitate ventilation due to weakening of muscles of respiration, are common throughout the literature. Less commonly, tremors are noted. This is the first known report of neuromuscular signs recognized and rapidly corrected in a dog. Although it is likely to be uncommon, hypophosphatemia should be recognized as a differential diagnosis in patients with tremors and/or muscle weakness.

[Case of pulmonary edema due to excessive hypertension following extubation].

A 54-year-old man had emergency laparoscopic chelecystectomy for acute cholecystitis. General inflammatory change (CRP 26.6 mg x dl(-1), WBC 26,800) was noted preoperatively. Anesthesia was induced with propofol and remifentanil and maintained with sevoflurane in oxygen and remifentanil. Operation was performed uneventfully within 128 min. At the end of the surgery, 0.1 mg of fentanyl was administrated. After confirming adequate respiration and oxygenation, endotracheal tube was removed. At that period, hypertension (SBP 220 mmHg) and tachycardia (HR 122 beats x min(-1)) developed. Soon thereafter, he became agitated and complained of dyspnea with desaturation (Spo2 < 70%). After reintubation, massive pinkish babbly secretion flowed out from the endotracheal tube. Chest X-ray revealed diffuse bilateral infiltration of the lungs without cardiomegaly. He was transferred to the intensive care unit for mechanical ventilation. His condition improved progressively and was extubated on the POD 6. The cause of pulmonary edema is thought to be profound centralization of circulating volume associated with catecholamine-induced vasoconstriction due to rapid disappearance of remifentanil effect. Adequate analgesia is necessary during remifentanil-based anesthesia especially in patients suffering from general inflammatory changes.

A 69-yr-old man underwent emergency laparotomy. He was in endotoxic shock. Preoperative evaluation including a full blood count, chest X-ray and ECG were normal. Body temperature was 37.4 degrees C. Preoperative arterial pressure was 140/80 mmHg and heart rate 65 bpm. Anesthesia was induced with ketamine 100 mg, propofol 20 mg, fentanyl 50 micrograms and vecuronium 4 mg and maintained with propofol 4 mg.kg-1.hr-1 and fentanyl. Soon after opening the abdominal peritoneum, severe bradycardia (< 20 bpm) occurred, but it was effectively treated by ephedrine 16 mg. After that, surgery was performed uneventfully. In the intensive care unit (ICU), the patient developed four episodes of severe atrioventricular (AV) block after stimulation of the trachea by suction drainage under sedation with propofol, although there was no AV block during sedation with ketamine and propofol. After stopping propofol, the AV block was no longer observed. He was discharged from the ICU on the 12th postoperative day. Postoperative Holter ECG and echocardiography showed no abnormalities. It is likely that stimulation of the trachea triggered vagovagal reflex and propofol prolonged AV conduction, causing the AV block.

Palatal versus vestibular piezoelectric window osteotomy for maxillary sinus elevation: a comparative clinical study of two surgical techniques.

PubMed

Stübinger, Stefan; Saldamli, Belma; Seitz, Oliver; Sader, Robert; Landes, Constantin A

2009-05-01

The goal of this study was to compare the surgical advantages and disadvantages of a new palatal access osteotomy for sinus elevation with a conventional lateral approach. In 32 patients, either a palatal (n = 16) or a lateral (n = 16) osteotomy to the maxillary sinus was performed under local anesthesia. The palatal access included a circular paramarginal incision and elevation of a palatal mucosal flap based on a median pedicle. The lateral access was performed by vestibular standard incision and development of a mucoperiosteal flap with a vestibular and superior basis. For all osteotomies a piezoelectric device was used. The sinus cavity was augmented with synthetic nanostructured hydroxyapatite graft material. Intraoperative complications during both procedures were minimal and wound healing was uneventful. Membrane perforation occurred in 19% of the palatal group and in 19% of the lateral group. Soft tissue management of the palatal technique was superior to that of the lateral approach, because the vestibular anatomy was not altered and consequently no disharmonious soft tissue scarring and no postoperative swelling occurred. The palatal approach permitted higher postoperative comfort, especially for edentulous patients, because full dentures could be incorporated directly after surgery with almost perfect fit.

Infections after PRK could have a happy ending: a series of three cases.

2010-04-01

Infectious keratitis after PRK remains a rare but potentially devastating complication. Medical records of 3 male patients with infectious keratitis after uneventful PRK for myopia and astigmatism were reviewed retrospectively. PRK was performed using the Wavelight Allegretto excimer laser. Postoperative care included a bandage contact lens (BCL) for 5 days, topical antibiotics, ketorolac, and artificial tears. Keratitis presented 2 - 4 days postoperatively. In one case, each culture was negative (case 1), and was positive for Streptococcus pneumoniae (case 2) and Staphylococcus aureus (case 3). Final BSCVA (best spectacle corrected visual acuity) after intensive antibiotic treatment and removal of BCL were 1.0 (case 1), 0.9 (case 2) and 0.3 correctable to 0.8 with pinhole (case 3). Postoperative broad-spectrum antibiotics are mandatory after PRK to prevent infectious keratitis. However, resistant organisms are more and more common. The presence of a bandage soft contact lens after surgery is an unfavourable element that may increase risk of infection. Based on our case series, we suggest limiting soft contact lens wear during the two postoperative days even if the corneal ulceration is not healed. Copyright Georg Thieme Verlag KG Stuttgart .

Mixed squamous cell and glandular papilloma (mixed papilloma) of the lung is exceedingly rare, with only 18 cases reported in the literature. Herein, we report a case of mixed papilloma and its associated immunohistochemical and positron emission tomographic (PET) findings. A 60-year-old Japanese male with a smoking history of 40 pack-years presented with a smooth-edged pulmonary lesion in the right S5 segment on computed tomography (CT). F18-fluorodeoxyglucose (FDG) PET revealed abnormally increased FDG uptake in the mass (maximum standardized uptake value, 3.4). We performed right middle lobectomy and combined partial resection of the S8 segment. The 1.8-cm tumor that filled the enlarged lumen of the B5b was histologically diagnosed as mixed papilloma. Immunohistochemically, the pseudostratified columnar epithelium was positive for cytokeratin (CK) 5/6 and CK7. p40 positivity was predominant in the basal and squamous cells. Thyroid transcription factor-1 and carcinoembryonic antigen were negative on immunostaining. Malignant features were absent. The postoperative course has been uneventful for 3 months after the surgery. No recurrences were reported after the surgical resection of the mixed papilloma. Therefore, surgical resection may be considered the mainstay of curative treatment.

We gave anesthesia for tracheal separation in a patient with Creutzfeldt-Jakob disease. The patient, a 33-year-old woman, was bedridden and unable to communicate, and was going to undergo a tracheal separation procedure for repeated bouts of aspiration pneumonia. After a tracheostomy with local anesthesia and sedation with propofol, general anesthesia was induced and maintained with propofol (1.5-3.0 microg x ml(-1), target controlled infusion) and remifentanil (0.05-0.15 microg x kg(-1) x min(-1)). We did not use an anesthetic apparatus from the standpoint of infection control, and provided manual ventilation with a disposable Jackson-Rees circuit. During the operation, an entropy monitor indicated alternating extremely low (0-10) and high (90-100) values without circulatory change, probably due to a previously existing electroencephalographic abnormality. The surgery was uneventful, and spontaneous breathing and eyelid opening occurred about 10 minutes after discontinuation of remifentanil and propofol. In such infected patients, abnormal prion proteins can exist outside of the central nervous system throughout the period of anesthetic management. Therefore, careful infection control must be undertaken, even if the surgical site is not directly related to the central nervous system.

Traumatic Tricuspid Insufficiency Requiring Valve Repair in an Acute Setting.

Tricuspid insufficiency due to penetrating cardiac trauma is rare. Patients with tricuspid insufficiency due to trauma can tolerate this abnormality for months or even years. We report a case of a 66-year-old female with penetrating cardiac trauma on the right side of her heart that required tricuspid valve repair in an acute setting. She sustained cut and stab wounds on her bilateral forearms and in the neck and epigastric region. She had cardiac tamponade and developed pulseless electrical activity, which required emergency surgery. The right ventricle and superior vena cava were dissected approximately 5 cm and 2 cm, respectively. After these wounds had been repaired, the patient's inability to wean from cardiopulmonary bypass suggested rightsided heart failure; transesophageal echocardiography revealed tricuspid insufficiency. Right atriotomy was performed, and a detailed examination revealed that the tricuspid valve septal leaflet was split in two. There was also an atrial septal injury that created a connection with the left atrium; these injuries were not detected from the right ventricular wound. After repair, weaning from cardiopulmonary bypass with mild tricuspid insufficiency was achieved, and she recovered uneventfully. This case emphasized the importance of thoroughly investigating intracardiac injury and transesophageal echocardiography.

The isolate resection of the uncinate process of the pancreas is a rarely described procedure but is an adequate surgery to treat benign and low grade malignancies of the uncinate process of the pancreas. To detail laparoscopic uncinatectomy technique and present the initial results. Patient is placed in supine position with the surgeon between legs. Three 5-mm, one 10-mm and one 12-mm trocars were used to perform the isolated resection of the uncinate process of the pancreas. Parenchymal transection is performed with harmonic scalpel. A hemostatic absorbable tissue is deployed over the area previously occupied by the uncinate process. A Waterman drain is placed. This procedure was applied to an asymptomatic 62-year-old male with biopsy proven low grade neuroendocrine tumor of the pancreatic uncinate process. A laparoscopic pancreaticoduodenectomy was proposed. During the initial surgical evaluation, intraoperative sonography was performed and disclosed that the lesion was a few millimeters away from the Wirsung. The option was to perform a laparoscopic uncinatectomy. Postoperative period until full recovery was swift and uneventful. Laparoscopic uncinatectomy is a safe and efficient procedure when performed by surgical teams with large experience in minimally invasive biliopancreatic procedures.

Hormonal treatment of transgender people is becoming a normal part of medicine, though numbers of subjects remain small because of low prevalence. Information on treatment is scattered and this review brings together the latest information on treatment goals and potential side-effects of androgen treatment of female-to-male transsexual subjects. Androgen treatment of female-to-male transsexuals is usually uneventful, with a good patient compliance. Goals of hormonal treatment are elimination of secondary sex characteristics of the female sex and induction of those of the male sex. Completion takes approximately 2 years. Hormonal treatment is eventually followed by surgical ablation of breasts and removal of uterus and ovaries. Phalloplasty may be considered. Concerns are the sequelae of hypogonadism following surgery, such as loss of bone mass. Contrary to earlier expectations, there is no increase in cardiovascular disease. (Hormone-related) cancers are rare, but vaginal, cervical, endometrial carcinomas have been reported. Cancers of the breasts are of greater concern and have been found in residual mammary tissue after breast ablation. So far, androgen treatment has not raised major safety concerns. Regrets about changing sex have not been reported. Testosterone treatment of female-to-male transsexuals is effective and well tolerated.

Case summary A 12-year-old neutered male domestic shorthair cat was presented to our referral hospital with a chronic history of tenesmus and lumbosacral pain. A diagnosis of degenerative lumbosacral stenosis (DLSS) was made and a standard dorsal L7–S1 laminectomy was performed uneventfully, with complete recovery within 1 month. The cat was brought back 4 months later for investigation of lumbosacral pain after having suffered a minor traumatic event. Neurological examination identified a low tail carriage, weakness, exercise intolerance, left pelvic limb lameness and diminished withdrawal reflexes in both pelvic limbs with severe sacrocaudal pain. A traumatic facet fracture of the L7 articular processes and subsequent spondylolisthesis was diagnosed. A second surgery was performed to stabilise the region. The cat was normal on neurological examination 1 month later and no further clinical signs were noted. Relevance and novel information This is the first description of a fracture and spondylolisthesis as a possible postoperative complication after L7–S1 dorsal laminectomy in a cat. The case highlights the importance of postoperative changes in the supportive structures of the lumbosacral spine in cats after surgical treatment of DLSS. PMID:29552353

Klippel-Feil syndrome (KFS) has a classical triad that includes short neck, low hair line and restriction in neck motion and is among one of the congenital causes of difficult airway. Herein, we present a 26-day, 3300g newborn with KFS who was planned to be operated for correction of an intestinal obstruction. She had features of severe KFS. Anesthesia was induced by inhalation of sevoflurane 2-3% in percentage 100 oxygen. Sevoflurane inhalation was stopped after 2min. Her Cornmack Lehane score was 2 and oral intubation was performed with 3.5mm ID non-cuffed endotracheal tube in first attempt. Operation lasted for 45min. Following uneventful surgery, she was not extubated and was transferred to the newborn reanimation unit. On the postoperative third day, the patient died due to hyperdynamic heart failure. This case is the youngest child with Klippel-Feil syndrome in literature and on whom oral intubation was performed. We also think that positioning of this younger age group might be easier than older age groups due to incomplete ossification process. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

We report a case of paroxysmal supraventricular tachycardia (PSVT) that occurred during video-assisted thoracoscopic (VATS) lobectomy in a patient with concealed Wolff-Parkinson-White (WPW) syndrome. A 59-year-old man with lung cancer was scheduled for VATS lobectomy under general anesthesia. After inserting a thoracic epidural catheter, general anesthesia was induced with intravenous administration of propofol. Anesthesia was maintained with inhalation of desfurane in an air/oxygen mixture and intravenous infusion of remifentanil. Recurrent PSVT occurred three times, and the last episode of PSVT continued for 50 minutes regardless of administration of antiarrhythmic drugs. Synchronized electric shock via adhesive electrode pads on the patient's chest successfully converted PSVT back to normal sinus rhythm. The remaining course and postoperative period were uneventful. An electrophysiological study performed after hospital discharge detected concealed WPW syndrome, which had contributed to the development of atrioventricular reciprocating tachycardia. Concealed WPW syndrome is a rare, but critical complication that could possibly cause lethal atrial tachyarrhythmias during the perioperative period. In the present case, cardioversion using adhesive electrode pads briefly terminated PSVT in a patient with concealed WPW syndrome.

Pancreaticojejunostomy, hepaticojejunostomy and double Roux-en-Y digestive tract reconstruction for benign pancreatic diseases.

Surgery such as digestive tract reconstruction is usually required for pancreatic trauma and severe pancreatitis as well as malignant pancreatic lesions. The most common digestive tract reconstruction techniques (e.g., Child's type reconstruction) for neoplastic diseases of the pancreatic head often encompass pancreaticojejunostomy, choledochojejunostomy and then gastrojejunostomy with pancreaticoduodenectomy, whereas these techniques may not be applicable in benign pancreatic diseases due to an integrated stomach and duodenum in these patients. In benign pancreatic diseases, the aforementioned reconstruction will not only increase the distance between the pancreaticojejunostomy and choledochojejunostomy, but also the risks of traction, twisting and angularity of the jejunal loop. In addition, postoperative complications such as mixed fistula are refractory and life-threatening after common reconstruction procedures. We here introduce a novel pancreaticojejunostomy, hepaticojejunostomy and double Roux-en-Y digestive tract reconstruction in two cases of benign pancreatic disease, thus decreasing not only the distance between the pancreaticojejunostomy and choledochojejunostomy, but also the possibility of postoperative complications compared to common reconstruction methods. Postoperatively, the recovery of these patients was uneventful and complications such as bile leakage, pancreatic leakage and digestive tract obstruction were not observed during the follow-up period.

Clinical estimation of different modifications of phacoemulsification revealed the formation of the second tunnel in the nucleus for its division into quadrants in "four-quadrant phaco" increases the required duration of ultrasonography (US) and irrigation, which causes greater endothelial losses associated with the use of nuclear breakdown by means of a chopper tunnel. When the authors used their own methods of "extracapsular half-nuclei" fragmentation, endothelial losses are rather greater than those with the similar method "stop & "chop", which is associated with closer disposition of the US tip to the posterior corneal surface. At the same time nuclear breakdown by means a chapper in the capsular sac by the "stop & chop" method causes dilation of Zinn's ligaments, fraught by their rupture, particularly if latent derangement or defects of the zonular apparatus, and increases the risk of damage to the posterior capsule by the chopper.

Unverified penicillin allergy label has negative health implications. To address this, several delabeling methods have been proposed. To appraise the long-term outcomes of the penicillin allergy evaluation in ambulatory patients, focusing on subsequent use of penicillins in individuals found not allergic. A secondary objective was to examine the consistency between the evaluation's recommendations and the allergy label. A retrospective medical records review and phone survey were carried out in ambulatory patients who were evaluated for suspected penicillin allergy in our allergy unit. Patients with an uneventful oral challenge test (OCT) were interviewed regarding subsequent use of penicillins. Medical records were examined for antibiotic prescriptions and purchases. The records were also investigated for existing/erased penicillin allergy label and its consistency with the allergy evaluation. Six hundred thirty-nine patients with an uneventful OCT were available for the survey. During a 56-month follow-up, 70% (447 patients) had used penicillins at least once. One hundred ninety-two patients (30%) did not use penicillins. The main reason for not using penicillins was lack of a clinical indication. Three hundred thirty-five patients (51.22%) carried a penicillin allergy label in their electronic medical file in spite of an uneventful OCT. Penicillin allergy annulling via OCT has proven to be effective. Most of the patients who previously avoided penicillins have reused penicillins safely.

The purpose of this study was to evaluate blood loss and procedure-related complications during and after surgical removal of retained products of conception with high-velocity enhanced myometrial vascularity. We conducted a prospective study of 18 consecutive women with a diagnosis of retained products of conception and enhanced myometrial vascularity, with a peak systolic velocity (PSV) higher than 60 cm/s. All underwent ultrasound-guided surgical removal of the retained products under general anesthesia. Blood loss during the procedure was collected and recorded. The removed tissue was sent for histologic examination. An ultrasound examination was repeated within 24 hours. Five patients had retained products of conception after a term delivery, 1 after a second-trimester termination of pregnancy, 7 after a spontaneous first-trimester miscarriage, and 5 after a first-trimester termination elsewhere. The PSV in the area of enhanced myometrial vascularity at diagnosis ranged from 61.0 to 152.6 cm/s (mean, 104.9 cm/s). The estimated blood loss at surgery ranged from 20 to 1000 mL (mean, 200 mL). After surgery, the PSV in the myometrium dropped dramatically (≤30 cm/s in all but 1 case). In all cases, trophoblastic tissue was confirmed at histologic examination. Although surgical removal of retained products of conception was uneventful in most cases, heavy bleeding has to be anticipated in cases of high-velocity flow in the myometrium underlying residual trophoblastic tissue. Accordingly, in cases of high-velocity enhanced myometrial vascularity, we advocate surgical removal of the residual tissue under ultrasound guidance by an experienced surgeon and in the presence of a fully informed anesthetist. © 2015 by the American Institute of Ultrasound in Medicine.

Intractable duodenal ulcer caused by transmural migration of gossypiboma into the duodenum--a case report and literature review.

Gossypiboma is a term used to describe a mass that forms around a cotton sponge or abdominal compress accidentally left in a patient during surgery. Transmural migration of an intra-abdominal gossypiboma has been reported to occur in the digestive tract, bladder, vagina and diaphragm. Open surgery is the most common approach in the treatment of gossypiboma. However, gossypibomas can be extracted by endoscopy while migrating into the digestive tract. We report a case of intractable duodenal ulcer caused by transmural migration of gossypiboma successfully treated by duodenorrhaphy. A systemic literature review is provided and a scheme of the therapeutic approach is proposed. A 61-year-old Han Chinese man presented with intermittent epigastric pain for the last 10 months. He had undergone laparoscopic cholecystectomy conversion to open cholecystectomy for acute gangrenous cholecystitis 10 months ago at another hospital. Transmural migration of gossypiboma into the duodenum was found. Endoscopic intervention failed to remove the entire gauze, and duodenal ulcer caused by the gauze persisted. Surgical intervention was performed and the gauze was removed successfully. The penetrated ulcer was repaired with duodenorrhaphy. The postoperative period was uneventful.We systematically reviewed the literature on transmural migration of gossypiboma into duodenum and present an overview of published cases. Our PubMed search yielded seven reports of transmural migration of retained surgical sponge into the duodenum. Surgical interventions were necessary in two patients. Transmural migration of gossypiboma into the duodenum is a rare surgical complication. The treatment strategies include endoscopic extraction and surgical intervention. Prompt surgical intervention should be considered for emergent conditions such as active bleeding, gastrointestinal obstruction, or intra-abdominal sepsis. For non-emergent conditions, surgical intervention could be considered for intractable cases in which endoscopic extraction failed.

To evaluate the visual outcomes after femtosecond laser-assisted laser in situ keratomileusis (LASIK) surgery to correct primary compound hyperopic astigmatism with high cylinder using a fast repetition rate excimer laser platform with optimized aspheric profiles and cyclotorsion control. Eyes with primary simple or compound hyperopic astigmatism and a cylinder power ≥3.00 D had uneventful femtosecond laser-assisted LASIK with a fast repetition rate excimer laser ablation, aspheric profiles, and cyclotorsion control. Visual, refractive, and aberrometric results were evaluated at the 3- and 6-month follow-up. The astigmatic outcome was evaluated using the Alpins method and ASSORT software. This study enrolled 80 eyes at 3 months and 50 eyes at 6 months. The significant reduction in refractive sphere and cylinder 3 and 6 months postoperatively (p<0.01) was associated with an improved uncorrected distance visual acuity (p<0.01). A total of 23.75% required retreatment 3 months after surgery. Efficacy and safety indices at 6 months were 0.90 and 1.00, respectively. At 6 months, 80% of eyes had an SE within ±0.50 D and 96% within ±1.00 D. No significant differences were detected between the third and the sixth postoperative months in refractive parameters. A significant increase in the spherical aberration was detected, but not in coma. The correction index was 0.94 at 3 months. Laser in situ keratomileusis for primary compound hyperopic astigmatism with high cylinder (>3.00 D) using the latest excimer platforms with cyclotorsion control, fast repetition rate, and optimized aspheric profiles is safe, moderately effective, and predictable.

Thirty-six systemically healthy patients, presenting with oral implants displaced into the maxillary sinus, but with no signs of acute or chronic sinusitis, were consecutively treated between 2002 and 2012 via an intraoral approach with the bony window technique. Removal of oral implants from the maxillary sinus was achieved in all patients, and postoperative recovery was uneventful in all of them. Computed tomographies performed after surgery showed no signs of residual sinus infection in all patients and a complete ossification of the bony window margins. Twelve of the 36 treated patients were treated with a sinus grafting procedure 12-18 months after in the same areas previously treated with the bone lid technique. Seventeen implants were placed in the grafted areas 6-9 months later and, after a further waiting period needed for osseointegration, the treated patients were rehabilitated with implant-supported prostheses. The survival rate of implants was 100%, and no complications related to the sinuses and implants were recorded. Results from this study seem to demonstrate that the bony window technique is a safe and easy way to remove oral implants from the maxillary sinus under local anesthesia. The surgical access is hardly visible 6-12 months after surgery, and maxillary sinuses appeared free from residual pathology in all treated patients. Finally, this procedure allows a second-stage sinus grafting procedure via a lateral approach as in a previously untreated maxillary sinus, thus allowing an implant-supported prosthetic restoration. © 2013 John Wiley & Sons A/S.

This study was designed to assess whether altered RV geometry and deformation parameters persisted well into the recovery period after presumably uncomplicated coronary artery bypass grafting (CABG). It was our hypothesis that the altered geometry of and load in the RV following pericardial opening would change both regional and global deformation indices for an extensive period postoperatively. Fifty-seven patients scheduled for CABG underwent preoperative and 8-10 months postoperative magnetic resonance imaging (MRI) for RV volume measurements, and resting echocardiography with assessment of geometry and RV mechanical function determined by tissue Doppler imaging (TDI) based longitudinal strain. Both MRI and echocardiography revealed postoperative dilatation of the RV apex, shortened longitudinal RV length but unchanged RV ejection fraction. Echocardiography parameters associated with filling of the right atrium showed signs of constraint with a reduced systolic filling fraction and increased right atrial size. Right ventricular segmental strain (-20 ± 13% vs. -29 ± 20% preoperatively; mean ±SD, P < 0.0001) was reduced postoperatively in parallel with TAPSE (1.3 ± 0.3 cm vs. 2.2 ± 0.4 cm; P < 0.0001). Post-CABG longitudinal motion of the RV lateral wall is reduced after uneventful CABG despite preserved RV ejection fraction and stroke volume. The discrepancy in various RV systolic performance indicators results from increased sphericity of the RV following opening the pericardium during surgery. Therefore, longitudinal functional parameters may underestimate RV systolic function for at least 8-10 months post-CABG. Changes in deformation parameters should thus always be interpreted in relation to changes in geometry. © 2015, Wiley Periodicals, Inc.

To show a video of a complete supine Percutaneous Nephrolithotomy (csPCNL) performed for the treatment of a staghorn calculus, from the surgeon's point of view. The procedure was recorded with a GoPro® camera, demonstrating the ten essential steps for a successful procedure. The patient was a 38 years-old woman with 2.4cm of left kidney lower pole stone burden who presented with 3 months of lumbar pain and recurrent urinary tract infections. She had a previous diagnosis of polycystic kidney disease and chronic renal failure stage 2. CT scan showed two 1.2cm stones in the lower pole (Guy's Stone Score 2). She had a previous ipsilateral double J insertion due to an obstructive pyelonephritis. The csPCNL was uneventful with a single access in the lower pole. The surgeon had a Full HD GoPro Hero 4 Session® camera mounted on his head, controlled by the surgical team with a remote control. All of the mains steps were recorded. Informed consent was obtained prior to the procedure. The surgical time was 90 minutes. Hemoglobin drop was 0.5g/dL. A post-operative CT scan was stone-free. The patient was discharged 36 hours after surgery. The camera worked properly and didn't cause pain or muscle discomfort to the surgeon. The quality of the recorded movie was excellent. GoPro® camera proved to be a very interesting tool to document surgeries without interfering with the procedure and with great educational potential. More studies should be conducted to evaluate the role of this equipment. Copyright® by the International Brazilian Journal of Urology.

Type A Dissection in pregnancy is a devastating medical condition with 2 lives at stake and unclear strategy at early gestational stages. We describe a successful outcome, clearly dependent on the coordination of all involved disciplines. This case history describes a 28 year old female with a 24th week pregnancy gravida 2 para 0 with a DeBakey Type I aortic dissection, diagnosed via ultrasound. Surgery was perfomed on the day of diagnosis. After conferral with the mother, caesarean section was performed and a 690 g fetus could be delivered and was immediately transferred to the neonatal unit. Subsequent aortic repair was performed after hysterectomy, with replacement of the ascending aorta and hemiarch treatment. Intraoperatively no entry in the ascending aorta or transverse arch could be demonstrated, so that a retrograde Type A with entry distal to the left subclavian had to be postulated. We decided to perform subsequent computer tomography, demonstrating multiple entry sites in the descending aorta distal to the left subclavian artery. Successful endovascular treatment could be performed with a Medtronic Valiant Stent via a transfemoral approach. The further hospital stay was uneventful and the patient could be discharged on the 18th postoperative day. The baby demonstrated fighter qualities and could be discharged home after a 3 month hospital stay to be reunited with his mother. Prompt diagnosis, precise coordination between all involved subspecialties and ultimately, as in this case, definitive treatment in consensus with operative and interventional departments have led to a successful outcome and encourages us in our daily struggle in this often demanding surgery.

Primary hyperparathyroidism is one of the most common endocrine disorders requiring surgical parathyroidectomy for its definitive treatment. Surgical exploration is traditionally performed through conventional open neck approach. A wide range of minimal access and minimally invasive endoscopic techniques (gas less and with gas) have been attempted in the past two decades. In this context, we evaluated the feasibility and safety of an innovative transoral endoscopic parathyroidectomy (EP) technique, which represents a paradigm shift in transluminal endocrine surgery. This is a prospective study conducted at a tertiary care Endocrine Surgery Department in South India between May 2016 and August 2017. We employed a novel transoral, lower vestibular route for EP. All the clinical, investigative, operative, pathological and post-operative data were collected from our prospectively filled database. Statistical analysis was performed with SPSS 20.0 version. Under inhalational general anaesthesia, access to the neck was obtained with 3 ports (central frenulotomy and two lateral port sites), dissected in subplatysmal plane and insufflated with 6 mm Hg CO 2 for working space. Rest of surgical steps is similar to conventional open parathyroidectomy. Out of the 38 hyperparathyroidism cases operated during the study, 12 (32%) were operated by this technique. Mean operative time was 112 ± 15 min (95-160). The post-operative course was uneventful with no major morbidity, hypocalcemia or recurrent laryngeal nerve palsy. Cure and diagnosis were confirmed by> 50% fall in intraoperative parathyroid hormone levels and histopathology (all were benign solitary adenomas). Through this study, we opine that this novel transoral vestibular route parathyroidectomy is a feasibly applicable approach for primary sporadic hyperparathyroidism, especially with solitary benign adenomas.

Regional anesthesia is gaining popularity with anesthesiologists as it offers superb postoperative analgesia. However, as the sole anesthetic technique in high-risk patients in whom general anesthesia is not preferred, some regional anesthetic possibilities may be easily overlooked. By presenting two cases of very old patients with considerable comorbidities, we would like to bring the mental nerve field block under renewed attention as a safe alternative to general anesthesia and to achieve broader application of this simple nerve block. Two very old male patients (84 and 91 years) both presented with an ulcerative lesion at the lower lip for which surgical removal was scheduled. Because of their considerable comorbidities and increased frailty, bilateral blockade of the mental nerve was considered superior to general anesthesia. As an additional advantage for the 84-year-old patient, who had a pneumonectomy in his medical history, the procedure could be safely performed in a beach-chair position to prevent atelectasis and optimize the ventilation/perfusion ratio of the single lung. The mental nerve blockades were performed intraorally in a blind fashion, after eversion of the lip and identifying the lower canine. A 5 mL syringe with a 23-gauge needle attached was passed into the buccal mucosa until it approximated the mental foramen, where 2 mL of lidocaine 2% with adrenaline 1:100.000 was injected. The other side was anesthetized in a similar fashion. Both patients underwent the surgical procedure uneventfully under a bilateral mental nerve block and were discharged from the hospital on the same day. A mental nerve block is an easy-to-perform regional anesthetic technique for lower lip surgery. This technique might be especially advantageous in the very old, frail patient.

To assess the reliability of corneal epithelial thickness (CET), nonepithelial central corneal thickness (NECCT), and central corneal thickness (CCT) measurements using Cirrus high-definition optical coherence tomography (HD-OCT) in patients who did and did not undergo cataract surgery. Forty patients who underwent uneventful phacoemulsification and 40 healthy participants were recruited to evaluate the intraobserver repeatability and interobserver reproducibility of CET, NECCT, and CCT measurements using Cirrus HD-OCT. To analyze repeatability, one examiner obtained 5 consecutive scans in each participant; for interobserver reproducibility, another examiner randomly obtained another scan. Within-subject standard deviation, coefficient of variation (CV), limits of agreement, and intraclass correlation coefficient (ICC) data were obtained. For intraobserver repeatability, the intrasession CV (CVw) and ICC values of the CET in the operated and nonoperated groups were 3.7% and 0.80 and 3.8% and 0.73, respectively; for NECCT, 0.7% and 0.98 and 0.8% and 0.97; and for CCT, 0.6% and 0.99 and 0.7% and 0.98. For interobserver reproducibility, the CVw and ICC values for the CET in the operated and nonoperated groups were 2.6% and 0.82 and 2.3% and 0.62, respectively; for NECCT, 0.7% and 0.98 and 0.5% and 0.98; and for CCT, 0.5% and 0.99 and 0.4% and 0.99. The corneal sublayer thickness can be measured reliably using Cirrus HD-OCT in patients who underwent cataract surgery and elderly participants; however, the CET consistency is poorer than the NECCT. Corneal epithelial thickness modifications exceeding 4% reflect true thickness changes instead of random error variations using HD-OCT.

Pedicle subtraction osteotomy (PSO) is an effective technique to correct fixed sagittal malalignment. A variation of this technique, the "trans-discal" or "extended" PSO (Schwab grade IV osteotomy), involves extending the posterior wedge resection of the index vertebra to include the superior adjacent disc for radical discectomy. The posterior wedge may be resected in asymmetric fashion to correct concurrent global coronal malalignment.This video illustrates the technical nuances of an extended asymmetrical lumbar PSO for adult spinal deformity. A 62-yr-old female with multiple prior lumbar fusions presented with worsening back pain and posture. Preoperative scoliosis X-rays demonstrated severe global sagittal and coronal malalignment (sagittal vertical axis [SVA, C7-plumbline] of 13.5 cm, pelvic incidence [PI] of 60°, lumbar lordosis [LL] of 14° [in kyphosis], pelvic tilt [PT] of 61°, thoracic kyphosis [TK] of 18°, and rightward coronal shift of 9.3 cm). The patient gave informed consent to surgery and for use of her imaging for medical publication. Briefly, surgery first involved transpedicular instrumentation from T10 to S1 with bilateral iliac screw fixation, and then T11-12 and T12-L1 Smith-Petersen osteotomies were performed. Next, an extended asymmetrical L4 PSO was performed and a 12° lordotic cage (9 × 14 × 40 mm) was placed at the PSO defect. Rods were placed from T10 to iliac bilaterally, and accessory supplemental rods spanning the PSO were attached. Postoperative scoliosis X-rays demonstrated improved alignment: SVA 5.5 cm, PI 60°, LL 55°, PT 36°, TK 37°, and 3.7 cm of rightward coronal shift. The patient had uneventful recovery.

Laparoendoscopic single site totally extraperitoneal (TEP) hernia repair showed to be a feasible alternative to conventional laparoscopic hernia repair; nevertheless single site surgery, with the loss of instruments triangulation can be a demanding procedure. To overcome those hurdles, the Single Site® (SS) platform of the da Vinci (DV) Si robotic system enables to perform surgical procedures through a 25-mm skin incision, with a stable 3D vision and restoring an adequate triangulation of the surgical instruments. We present in details the technique and the preliminary results of DV-SS TEP, to our knowledge the first cases reported in literature. In March 2016, three consecutive male patients (mean age 46.6 years-mean BMI 25.3) with bilateral symptomatic inguinal hernia were submitted to DV-SS TEP in our institutions. Feasibility, codification of the technique, operative time and perioperative outcomes were recorded. All the procedures were completed as scheduled, with no conversion to other techniques. Mean operative time was 98.6 min, ranging between 155 and 55 min, reflecting the learning curve of the operating room team on this new procedure. No intraoperative or postoperative complications were experienced and all the patients were discharged within 24 h after surgery. Patients reported satisfactory postoperative course, with no recurrence of inguinal hernia and satisfaction in cosmetic result at 6-month follow-up. DV-SS TEP inguinal hernia repair showed to be feasible and effective surgical option for bilateral groin hernia repair. Patients' outcome was uneventful, with optimal cosmetic results. Further studies comparing this innovative technique to TEP or LESS TEP should be promoted.

Preservation of keratinized mucosa around implants using a prefabricated implant-retained stent: a case-control study

PubMed Central

2016-01-01

Purpose The aim of this study was to clinically assess the impact of a prefabricated implant-retained stent clipped over healing abutments on the preservation of keratinized mucosa around implants after implant surgery, and to compare it with horizontal external mattress sutures. Methods A total of 50 patients were enrolled in this study. In the test group, a prefabricated implant-retained stent was clipped on the healing abutment after implant surgery to replace the keratinized tissue bucco-apically. In the control group, horizontal external mattress sutures were applied instead of using a stent. After the surgical procedure, the width of the buccal keratinized mucosa was measured at the mesial, middle, and distal aspects of the healing abutment. The change in the width of the buccal keratinized mucosa was assessed at 1 and 3 months. Results Healing was uneventful in both groups. The difference of width between baseline and 1 month was −0.26±0.85 mm in the test group, without any statistical significance (P=0.137). Meanwhile, the corresponding difference in the control group was −0.74±0.73 mm and it showed statistical significance (P<0.001). The difference of width between baseline and 3 months was −0.57±0.97 mm in the test group and −0.86±0.71 mm in the control group. These reductions were statistically significant (P<0.05); however, there was no difference between the 2 groups. Conclusions Using a prefabricated implant-retained stent was shown to be effective in the preservation of the keratinized mucosa around implants and it was simple and straightforward in comparison to the horizontal external mattress suture technique.

To report new information related to acute retinal toxicity of Bio Octane Plus, a mixture of 90% perfluorooctane (PFO) and 10% perfluorohexyloctane. This retrospective, descriptive case series reports the occurrence of acute retinal toxicity after vitreoretinal surgery in which Bio Octane Plus (batch number 1605148) was used as an endotamponade. Cytotoxicity biocompatibility tests and chemical analyses by Fourier-transformed infrared (FTIR) spectroscopy and gas chromatography-mass spectrometry (GC-MS) of the presumed toxic product were performed. Four patients presented with acute severe visual loss after uneventful ocular surgery assisted by Bio Octane Plus (batch number 1605148) as endotamponade. Patients experienced extensive retinal vascular occlusion leading to retinal and optic nerve atrophy. The viability of ARPE-19 cells directly exposed to the suspect batch for 30 min was 0%. The agarose overlay method used by the manufacturer according to European Union regulations and International Organization for Standardization (ISO) International Standards failed to detect toxicity. FTIR spectroscopy showed small differences between the non-toxic and toxic batches. GC-MS analysis showed the presence of bromotributyl stannane (whose toxicity was demonstrated in the dose-response curve) only in the toxic batch of Bio Octane Plus. This is the third report of retinotoxicity due to PFO in 4 years. The clinical profiles may be missed as they resemble other postsurgical complications; therefore, more cases worldwide could have gone unreported. Protocols to determine cytotoxicity of intraocular medical devices and approved by the ISO International Standards based on indirect methods have failed and should be revised to ensure safety. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

A fracture of root canal instruments, with a fractured piece protruding beyond the apex, is a troublesome incident during an endodontic treatment. Locating and retrieving them represents a challenge to maxillofacial surgeons because it is difficult to access due to the proximity between the foreign body and vital structures. Although safe and accurate for surgery, radiographs and electromagnetic devices do not provide a precise three-dimensional position. In contrast, computer-aided navigation provides a correlation between preoperatively collected data and intraoperatively encountered anatomy. However, using a navigation system for mandible treatment is difficult as the mobile nature of the mandible complicates its synchronization with the preoperative imaging data during surgery. This report describes a case of a dental instrument breakage in the mandible during an endodontic treatment for a restorative dental procedure in a 65-year-old Japanese woman. The broken dental instrument was removed using a minimally invasive approach with a surgical navigation system and an interocclusal splint for a stable, identically repeatable positioning of the mandible. Using the three-dimensional position of the navigation probe, a location that best approximated the most anterior extent of the fragment was selected. A minimally invasive vestibular incision was made at this location, a subperiosteal reflection was performed, and the foreign body location was confirmed using a careful navigation system. The instrument was carefully visualized and extruded from the apical to the tooth crown side and was then removed using mosquito forceps through the medullary cavity of the crown side of the tooth. Follow-up was uneventful; her clinical course was good. The use of a surgical navigation system together with an interocclusal splint enabled the retrieval of a broken dental instrument in a safe and minimally invasive manner without damaging the surrounding vital structures.

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.

To describe general anesthesia and successful treatment of an alpaca, which developed respiratory arrest 2 hours after intrathecal injection of morphine and bupivacaine. A 10-day-old female alpaca weighing 7.3 kg was presented to our hospital with a fractured right tibia. The cria was anesthetized to repair the fracture with a dynamic compression plate. Anesthesia was induced with IV propofol and maintained with sevoflurane in 100% oxygen. Prior to the start of surgery the alpaca received an unintended intrathecal injection of 0.6 mL of a solution of 0.5 mg morphine (0.068 mg/kg) and 1.5 mg bupivacaine (0.2 mg/kg), after an attempted lumbo-sacral epidural. The alpaca developed respiratory arrest 120 minutes after the intrathecal injection was administered. Adequate hemoglobin-oxygen saturation was maintained despite minimal intermittent manual ventilation, but marked hypercapnia developed (PaCO2 of 17.3 KPa [130 mm Hg]). Delayed respiratory depression resulting from cephalad migration of intrathecal morphine was suspected. Ventilation was supported until the end of surgery when sevoflurane was discontinued. The trachea remained intubated, 100% oxygen was supplied, and ventilation was supported at 2-4 breaths/min for the next 60 minutes, but no attempts to breathe spontaneously were detected. Intravenous naloxone (0.3 mg [0.04 mg/kg]) was administered slowly to effect until adequate spontaneous ventilation and full consciousness returned. The anesthetic recovery of the alpaca was rapid and uneventful after the opioid antagonist was given. Delayed respiratory depression is a potential complication after intrathecal administration of morphine. Careful dose-adjustment may reduce the risk, and close monitoring will result in early detection and treatment of this complication. © Veterinary Emergency and Critical Care Society 2014.

Metastasis of ovarian cancer to the breast (MOCB) is a rare event. Clinical presentations of MOCB vary and surgery is the mainstay of treatment. The current study presents two cases of MOCB in women with recurrent ovarian cancer first diagnosed in April 2011 and October 2013, respectively. The patients presented to the clinic with a localized, palpable, painful mass in the upper outer quadrant of the right breast and a centrally localized, palpable, painful mass of the left breast, respectively. Breast sonography and mammography showed a singular, round, homogenous tumor with irregular borders in each case. An ipsilateral enlarged axillary node was palpable in one case. Tumor biopsy revealed an undifferentiated adenocarcinoma of unknown origin in one case and a moderately-differentiated adenocarcinoma suspected to be breast cancer in the other case. Tumor cells were positive for estrogen receptor and paired box 8, and negative for GATA binding protein 3 in the two cases. Palliative mastectomy was performed in one case and lumpectomy with ipsilateral axillary sentinel node biopsy in the other case, and the final histology revealed MOCB in each. The post-operative course of the disease was uneventful and the patients continued with their ovarian cancer-specific chemotherapy. One patient succumbed to disease progression 2 months after breast surgery. The other patient remains alive and is currently undergoing systemic chemotherapy. The current study also presents a review of 110 cases of MOCB identified in a literature search of Pubmed. Data from these studies, including the clinical and histological characteristics of MOCB, and the clinical management and prognosis are discussed. Overall, MOCB is rare, with distinct clinical and histological features. The disease is usually treated with local surgical excision or mastectomy and has a poor prognosis. PMID:27313731

During the surgical removal of infratentorial lesions, intraoperative neuromonitoring is mostly focused on cranial nerve assessment and brainstem auditory potentials. Despite the known risk of perforating vessel injury during microdissection within the vicinity of the brainstem, there are few reports about intraoperative neuromonitoring with somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) assessing the medial lemniscus and corticospinal tract. This study analyses the occurrence of intraoperative changes in MEPs and SEPs with regard to lesion location and postoperative neurological outcome. The authors analyzed 210 cases in which patients (mean age 49 ± 13 years, 109 female) underwent surgeries involving the skull base (n = 104), cerebellum (n = 63), fourth ventricle (n = 28), brainstem (n = 12), and foramen magnum (n = 3). Of 210 surgeries, 171 (81.4%) were uneventful with respect to long-tract monitoring. Nine (23%) of the 39 SEP and/or MEP alterations were transient and were only followed by a slight permanent deficit in 1 case. Permanent deterioration only was seen in 19 (49%) of 39 cases; the deterioration was related to tumor dissection in 4 of these cases, and permanent deficit (moderate-severe) was seen in only 1 of these 4 cases. Eleven patients (28%) had losses of at least 1 modality, and in 9 of these 11 cases, the loss was related to surgical microdissection within the vicinity of the brainstem. Four of these 9 patients suffered a moderate-to-severe long-term deficit. For permanent changes, the positive predictive value for neuromonitoring of the long tracts was 0.467, the negative predictive value was 0.989, the sensitivity was 0.875, and the specificity 0.918. Twenty-eight (72%) of 39 SEP and MEP alterations occurred in 66 cases involving intrinsic brainstem tumors or tumors adjacent to the brainstem. Lesion location and alterations in intraoperative neuromonitoring significantly correlated with patients' outcome (p < 0.001, chi-square test). In summary, long-tract monitoring with SEPs and MEPs in infratentorial surgeries has a high sensitivity and negative predictive value with respect to postoperative neurological status. It is recommended especially in those surgeries in which microdissection within and in the vicinity of the brainstem might lead to injury of the brainstem parenchyma or perforating vessels and a subsequent perfusion deficit within the brainstem.

In spite of availability of cost-effective preventive measures and treatment, a resurgence of congenital syphilis has currently been noted. During the past 4 years, we came across five low birth weight neonates with unusual symptoms, which subsequently proved to be manifestations of early congenital syphilis. All the mothers had apparently uneventful antenatal period. No investigation was done during pregnancy. They were unaware about their disease and were found to be positive for syphilis by Venereal Disease Research Laboratory Test and fluorescent treponemal antibody (absorbed) IgM test only after childbirth. Screening for other congenital infections was negative. All the neonates were positive for Venereal Disease Research Laboratory Test. They were treated with intravenous crystalline penicillin G for 10 days. Recovery was uneventful. We reemphasize the importance of raising public awareness, routine antenatal screening and treatment for all pregnant mothers to avoid such a potentially treatable condition.

A 36-year-old, healthy, primiparous female underwent a caesarean section under general anaesthetic. She had previously had a severe reaction to dye during a myelogram and therefore, had declined epidural analgesia or regional anaesthesia. Induction and maintenance of anaesthesia was uneventful, but on emergence, and before tracheal extubation, the patient coughed on the endotracheal tube and almost immediately developed right-sided subcutaneous emphysema of the face and neck. At this point her oxygen saturation began to fall and she was noted to be difficult to ventilate. Clinically and radiologically, she had a right-sided pneumothorax which was treated immediately with intercostal drain insertion. She went on to develop a left pneumothorax which also required intercostal drain insertion. She made an uneventful recovery and was discharged 8 days later. A subsequent CT scan of her chest revealed no pre-existing primary pulmonary pathology that would have accounted for the pneumothoraces. PMID:22927264

Cervical pregnancy (CP) is a rare type of ectopic pregnancy. While methotrexate (MTX) is generally the first-line method of choice for clinically stable women, there is still no consensus on the most appropriate treatment for this abnormal pregnancy. The aim of this study was to investigate the efficacy of a single local MTX injection under transvaginal ultrasound guidance for the initial treatment of CP and to assess post-treatment fertility. We reviewed retrospectively 15 patients with CP treated with local MTX injection under transvaginal ultrasound guidance. In all patients, the serum human chorionic gonadotropin (hCG) levels were monitored and the gestational sac was evaluated using ultrasonography after treatment. Magnetic resonance imaging (MRI) was performed as necessary. We evaluated the patients' clinical characteristics and clinical course after treatment, the efficacy of the treatment and the post-treatment fertility in patients desiring subsequent pregnancy. The median estimated gestational age at the time of MTX injection was 6 + 2 (range, 5 + 2 to 11 + 0) weeks. All 15 patients were treated successfully, without the need for blood transfusion or surgical procedures; however, three patients required an additional local MTX injection due to a poor decline in serum hCG level following the initial injection, while one patient required uterine artery embolization due to persistent vaginal bleeding and an enlarging gestational sac with blood vessels visible on contrast-enhanced MRI. The mean time following initial MTX injection for hCG normalization was 43.8 (95% CI, 33.3-54.3) days and for resumption of menses was 68.4 (95% CI, 51.9-84.9) days. Seven of the 10 women desiring subsequent pregnancy following treatment had uneventful pregnancy, one became pregnant but miscarried spontaneously at 8 weeks of gestation, one was treated by laparoscopic surgery after diagnosis of a tubal pregnancy and one did not conceive. A single, ultrasound-guided, local MTX injection is apparently effective for the treatment of CP without the need for concomitant procedures or surgical intervention. Furthermore, this conservative technique both preserves fertility and allows for the possibility of subsequent uneventful pregnancy. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Regional anaesthetic techniques have been used in combination with systemic analgesics during small animal surgery to provide multimodal analgesia. Brachial plexus nerves block using local anaesthetics provides analgesia of the thoracic limb through desensitization of the nerves that provide sensory and motor innervation. This has been shown to reduce intra-operative anesthetic requirements and provide postoperative pain relief. Decreasing the doses of general anaesthetics allows more stable cardiopulmonary function during anaesthesia and the development of less side effects. The present case reports a successful use of brachial plexus blockade to supplement medetomidine-ketamine-isoflurane anaesthesia for repair of radio-ulna fracture in an adult cheetah (acinonyx jubatus). An adult male Cheetah weighing about 65 kg was presented with a history of leg carrying lameness of the left forelimb sustained following a car accident a week earlier. Clinical examination under general anaesthesia revealed slight dehydration and a swelling with a wound on the caudo-medial aspect of the left radio-ulna region. Crepitation was present on manipulation and radiography confirmed a complete transverse radio-ulna fracture of the left forelimb, which required open reduction and internal fixation. Brachial plexus blockade using lignocaine hydrochloride was used to supplement medetomidine-ketamine-isoflurane anaesthesia for the surgical procedure. Isoflurane anaesthesia was maintained at 0.5 - 2.0% throughout the surgical procedure, which was uneventful. Temperature and cardio-pulmonary parameters remained stable intra-operatively. Limb paralysis extended for 5 hours post-operatively, suggesting prolonged anaesthesia. To the researchers' knowledge, this is the first reported case of the use of brachial plexus blockade to supplement general anaesthesia to facilitate forelimb surgery in an adult cheetah. The use of brachial plexus block with a light plane of general anaesthesia proved to be successful. Brachial plexus block had a sparing effect on isoflurane anaesthesia as evidenced by the concentration used for maintenance of anaesthesia and the stability of the cardiopulmonary function. Moreover, absence of autonomic cardiopulmonary reactions to the surgical manipulation may be attributed to the efficacy of brachial plexus block. This anaesthesia protocol is therefore recommended for surgeries of the forelimb in wild cats.

AIM: To study the transcolonic extraction of the proximally resected colonic specimens by colonoscopic assistance at laparoscopic colonic surgery. METHODS: The diagnoses of our patients were Crohn’s disease, carcinoid of appendix and adenocarcinoma of cecum. We preferred laparoscopic total mesocolic resections. Colon and terminal ileum were divided with endoscopic staplers. A colonoscope was placed per anal and moved proximally in the colon till to reach the colonic closed end under the laparoscopic guidance. The stump of the colon was opened with laparoscopic scissors. A snare of colonoscope was released and the intraperitoneal complete free colonic specimen was grasped. Specimen was moved in to the colon with the help of the laparoscopic graspers and pulled gently through the large bowel and extracted through the anus. The open end of the colon was closed again and the ileal limb and the colon were anastomosed intracorporeally with a 60-mm laparoscopic stapler. The common enterotomy orifice was closed in two layers with a running intracorporeal suture. RESULTS: There were three patients with laparoscopic right-sided colonic resections and their specimens were intended to remove through the remnant colon by colonoscopy but the procedure failed in one patient (adenocarcinoma) due to a bulky mass and the specimen extraction was converted to transvaginal route. All the patients had prior abdominal surgeries and had related adhesions. The operating times were 210, 300 and 500 min. The lengths of the specimens were 13, 17 and 27 cm. In our cases, there were no superficial or deep surgical site infections or any other complications. The patients were discharged uneventfully within 4-5 d and they were asymptomatic after a mean 7.6 mo follow-up (ranged 4-12). As far as we know, there were only 12 cases reported yet on transcolonic extraction of the proximal colonic specimens by colonoscopic assistance after laparoscopic resections. With our cases, success rate of the overall experience in the literature was 80% (12/15) in selected cases. CONCLUSION: Transcolonic specimen extraction for right-sided colonic resection is feasible in selected patients. Both natural orifice surgery and intracorporeal anastomosis avoids mini-laparotomy for specimen extraction or anastomosis. PMID:26380054

Pyosalpinges (a complication of pelvic inflammatory disease) is infection of the fallopian tubes and the morbidity associated with it has major health implications. We are reporting a case of pyosalpinges diagnosed after hysterosalpingography and managed by laparoscopic surgery at the Douala General Hospital, Cameroon. A 29-year-old single woman, an assistant nurse of the Douala tribe in Cameroon. She is G1P0010 and came to our attention because of secondary infertility of three years duration. She has a history consistent with four lifetime sexual partners, self-medication for chlamydia trachomatis infection and induced abortion by dilatation and aspiration. Furthermore, she is HIV positive and had an ultrasound scan suggestive of bilateral hydrosalpinges. After a hysterosalpingography examination she developed painless muco-purulent vaginal discharge and bilateral adnexal tenderness on bimanual examination suggestive of pyosalpinges. Vaginal and cervical cultures isolated Ureaplasma urealyticum and Gardnerella vaginalis sensitive to ofloxacin and metronidazole, respectively.At laparoscopy, bilateral pyosalpinges, pelvic adhesions and peri-hepatic adhesions were found. Bilateral salpingectomy with adhesiolysis including lysis of perihepatic adhesions and peritoneal toileting was done. She was discharged from hospital 72 h later and her hospital stay was uneventful. She was counseled for in-vitro fertilization and to register in the national HIV treatment programme. Her husband was prescribed ofloxacin empirically. Antimicrobial prophylaxis should be given to patients prior to HSG, especially those with a history of chlamydia or evidence of hydrosalpinges. There should also be universal STI testing in high risk and HIV positive patients or the danger for suboptimal antibiotic usage in areas where self-medication is common.In resource-low tertiary hospitals where computed tomography or magnetic resonance imaging is not readily available and/or affordable, clinical examination and pelvic ultrasound remains the key diagnostic tool. Surgical treatment is the best option for pyosalpinges and when plausible, laparoscopic surgery is the treatment of choice. Laparotomy is the mainstay in most hospitals in Cameroon. The parent of the patient did not consent to histo-pathologic examination.

Background Despite considerable analysis and preventive strategies, brachial plexus injuries remain fairly common in the perioperative setting. These injuries range from brief periods of numbness or discomfort in the immediate postoperative period to, in rare cases, profound, prolonged losses of sensation and function. We present a case of an orthopedic surgery patient who suffered a brachial plexus injury while under anesthesia after trying to sit upright with his arms restrained. Case presentation After the uneventful placement of an intramedullary tibial nail, an 18 year old patient tried to sit upright with his arms restrained while still under the influence of anesthesia. In the immediate postoperative period, the patient complained of a profound loss of sensation in his left arm and an inability to flex his left elbow, suppinate his arm, or abduct and rotate his shoulder. Neurological examination and subsequent studies revealed a C5-6 brachial plexus injury. The patient underwent range of motion physical therapy and, over the next three months, regained the full function and sensation of his left arm. Conclusion Restraining arms during general anesthesia to prevent injury remains a wise practice. However, to avoid injuring the brachial plexus while the arms are restrained, extra caution must be used to prevent unexpected patient movement and to ensure gentle emergence. PMID:18271944

Cervical vertebral (C) malformation is rarely reported in large breed dogs. Congenital cervical kyphosis (CCK) may result from defects of vertebral segmentation, failure of formation or both. This report describes two cases of C3-C4 CCK in young sighthounds, treated surgically. An 18-month-old female Deerhound and a six-week-old female Borzoi dog were presented because of the complaints of reluctance to exercise and signs of of neck pain. Both dogs were neurologically normal. Diagnostic imaging revealed C3-C4 deformity, moderate kyphosis, and spinal canal stenosis associated with chronic spinal cord pressure atrophy. Both dogs underwent surgical treatment. A staged two-step surgery starting with dorsal decompression was elected in the Deerhound. After the first surgical procedure, the dog developed focal myelomalacia and phrenic nerve paralysis and was euthanatized. A ventral distraction-fusion technique with two locking plates was performed in the Borzoi. This patient recovered uneventfully and long-term follow-up computed tomography revealed complete spondylodesis. Until now, CCK has only been described in sighthounds. Congenital cervical kyphosis might be considered a differential diagnosis in these breeds that are presented with signs of cervical pain. Ventral realignment-fusion and bone grafting may be considered for surgical treatment, although the earliest age at which this procedure can and should be performed remains unclear.

Spontaneous spinal CSF leaks are best known as a cause of orthostatic headache, but may also be the cause of coma. The authors encountered a unique case of a spontaneous spinal CSF leak causing coma 2 days after craniotomy for clipping of an unruptured aneurysm. This 44-year-old woman with autosomal dominant polycystic kidney disease underwent an uneventful craniotomy for an incidental anterior choroidal artery aneurysm. No intraoperative spinal CSF drainage was used. Two days after surgery the patient became comatose with a left oculomotor nerve palsy. Computed tomography scanning revealed a right extraceberal hematoma and loss of gray-white matter differentiation. The hematoma was evacuated and a diagnosis of hemodialysis disequilibrium syndrome was made. Continuous hemodialysis and hyperosmolar therapy were instituted without any improvement. The CT scans were then reinterpreted as showing sagging of the brain, and the patient was placed in the Trendelenburg position which resulted in prompt improvement in her level of consciousness. A CT myelogram demonstrated an upper thoracic CSF leak that eventually required surgical correction. The patient made a complete neurological recovery. Neurological deterioration after craniotomy may be caused by brain sagging caused by a spontaneous spinal CSF leak, similar to intracranial hypotension due to intraoperative lumbar CSF drainage.

To evaluate the efficacy of combining preoperative immunosuppressive therapy with surgical excision for treatment of anal furunculosis (AF) in dogs. Retrospective study. Dogs (n=25) with stages 1-4 AF. Preoperative immunosuppressive therapy was either cyclosporine A (CyA) alone or in combination with ketoconazole (Group 1; n=18), or azathioprine combined with prednisolone (Group 2; n=7). Surgical excision of residual draining tracts, cryptectomy, and anal sacculectomy were performed. Only dogs with postoperative clinical follow-up exceeding 9 months were retained for the study. Both immunosuppressive protocols were effective in reducing progression of AF. Subsequent draining tracts excision, cryptectomy, and anal sacculectomy were bilateral (12 dogs) or unilateral (13 dogs of which 4 had bilateral anal sacculectomy). Postoperative recovery was uneventful, except for 2 dogs that had wound breakdown. Recurrence was not observed in any of the dogs that had bilateral surgical excision and or in 9 dogs that had unilateral excision. Preoperative immunosuppressive therapy, combined with bilateral surgical resection of affected tissue consistently, resulted in resolution of AF. Four dogs that had recurrence had unilateral excision despite initial bilateral involvement, suggesting that all diseased tissue should be excised. These preliminary results suggest that immunosuppressive therapy before surgical excision for AF yields minimizes recurrence in dogs.
