Surgery of cicatricial stage of choroidal neovascular membrane with autologous conditioned plasma

Purpose. To estimate the effectiveness of the cicatricial stage of choroidal neovascular membrane (CNM) surgery with retina fixation after retinotomy of paracentral areas with autologous conditioned platelet rich plasma (ACP) and without endolaser photocoagulation and silicone oil tamponade. Material and methods. 17 CNM patients aged 49 to 82 with visual acuity from 0.02 eccentric to 0.08 were operated. The operation consisted in 25-, 27+-gauge vitrectomy, removal of the posterior hyaloid membrane and the inner limiting membrane (in the presence of an epiretinal membrane), paracentral retinotomy, removal of the choroidal neovascular membrane via retinotomy, pneumoretinopexy, 2–3 layer instillation of ACP in the retinotomy area without endolaser photocoagulation and silicone oil tamponade, seamless closure of sclera- and conjunctivotomy with a layer of autologous conditioned plasma. Results. Full retinal reattachment and closure of the retinotomy opening in the late postoperative period was noted in all patients. No case of recurrent retinal detachment was recorded. Complete closure of sclera- and conjunctivotomy with no additional suture fixation was achieved in all cases. In the long-term period after the removal of the cicatricial choroidal membrane, visual acuity was 0.03–0.2. Conclusion. The modern surgery of the cicatricial stage of CNM using ACP to close the retinotomy defect after removal of cicatricial CNV without endolaser coagulation of the retina and silicone tamponade, followed by seamless blocking of the sclero- and conjunctivotomy with ACP produces excellent anatomical and functional results, minimizing the risk of postoperative complications.

Laser treatment of macular retinal folds in late postoperative period after retinal detachment repair

Macular retinal folds are a rare yet grave complication of surgical rhegmatogenous retinal detachment repair. Clinical symptoms vary depending on the location and severity of folding. Fold located in the periphery of the ocular fundus can be asymptomatic, but macular retinal folds cause diminished visual acuity and metamorphopsia. Currently, the most effective treatment for retinal folds is repeat surgery. Its serious disadvantage is the risk of complications in the early postoperative period, including hemophthalmia, inflammation, secondary glaucoma, cataracts, RRD recurrence, macular tears, retinal vascular occlusion, etc. The clinical case described below demonstrates the potential of combination laser therapy for the treatment of macular retinal folds based on the use of modern diagnostic and therapeutic methods.

Primary Adenocarcinoma at Colostomy Site: Report of a Clinical Case

Colorectal cancer (CRC) is the fourth most frequently diagnosed cancer in the United States and it is found in 17% of patients thought to have complicated diverticular disease. However, primary adenocarcinoma rarely occur in the colostomy site and the risk of developing malignancy is similar to that of any other colonic segment. Polyps found in CRC screenings can be divided into the following types: hyperplastic polyps, polyps with no malignant potential, adenomatous polyps, polyps with malignant potential, and malignancies. Local complications of the colostomy can appear in the immediate, early, or late postoperative period, with an incidence ranging from 15 to 30%; neoplasia is even less common.

The results of sphincterometry in patients after sorgion treatment of extrasphintery anal fistula

More than 30% of patients with chronic paraproctitis have complex forms. They are most often complicated by external sphincter insufficiency due to deformation of the anal canal and scarring of the sphincters. The main principle of substantiation of surgical treatment of extrasphincteric pararectal fistulas is the individual choice of method in each particular patient. It is based on a comprehensive assessment of such factors as the etiology of the fistula, its distance from the edge of the anus, the relationship of the defect or fistula with the sphincter muscles apparatus, the severity of the scarring process, the functional state of the rectum. Aim. Evaluation of the functional state of the sphincter apparatus of the rectum in patients with extrasphincteric pararectal fistulas in the preoperative, early and late postoperative periods. Materials and methods. To determine the average indicators of anal sphincter function, basal tone and maximal compression force were measured using a sphincterometer "Sphinctometer STM-0164-SM" in 114 healthy individuals (68 men and 46 women) of different ages (16 to 80 years) who objectively had no signs of anal incontinence. In all patients, sphincterometry was preceded by a thorough proctological examination, and proctological pathology was excluded. Therefore, hemorrhoids or anal fissures, which lead to increased basal tone at rest, were excluded so as not to lead to falsified values. Results. Indicators of the maximum compression force in the early postoperative period, ie the compression force of the external anal sphincter, in both groups were significantly lower than preoperative and ranged from 55 to 154 mm Hg, respectively. and from 63 to 137 mm Hg. This can be explained by the presence of a granulating wound in the pararectal tissue, edema and partial injury of the external anal sphincter during surgery. In the late postoperative period, 6-12 months after surgery, the indicators of basal tone in both groups approached the preoperative indicators. In the main group, the study was performed in 22 patients. In these 22 patients, the tone of the internal anal sphincter did not differ significantly from the preoperative and ranged from 20 to 37 mm Hg. In the control group, in all 32 patients, the basal tone of the anal sphincter was significantly lower than before surgery - from 17 to 28 mm Hg. There were no clinical manifestations of incontinence at rest in either main or control groups. In the late postoperative period in both groups a decrease in the maximum compression force of the external anal sphincter was revealed. In the main group the maximum compression force of the external anal sphincter varied from 71 to 186 mm Hg, and in the control group from 77 to 135 mm Hg, respectively. Conclusion. Surgical treatment of patients with extrasphincteric pararectal fistulas significantly reduces the contractile function of the external anal sphincter in the postoperative period, regardless of the choice of surgery.

Abdominal Viscera Migration Performing Hemodynamic Instability after Esophagectomy: A Case Report

Hiatal hernia is a rare postoperative complication of esophagectomy in the treatment of esophageal cancer. Although rare, its incidence increased after the establishment of minimally invasive surgical techniques. The patient is usually oligosymptomatic, and the diagnosis is made in the late postoperative period, during outpatient follow-up. The initial presentation of hiatus hernia with hemodynamic instability is a rare condition that has never been described in the literature before. In the following report, we address the clinical picture, diagnosis, and treatment for this condition, discussing the main nuances of the literature.

EMERGENCE DELIRIUM IN PEDIATRIC PATIENTS UNDERGOING GENERAL ANESTHESIA

Background: Emergence delirium (ED) is described as a transient state of cognitive disturbance and psychomotor agitation, which begins with emergence from anesthesia and continues through the early recovery period. The incidence of ED in the pediatric population remains unclear and ranges from 10 to 80%. The pathophysiology and underlying mechanisms of ED are also uncertain. This study aimed to determine the prevalence of ED, potential risk factors that may contribute to the development of ED and observe behaviour changes related to ED in the late postoperative period. Methods: A prospective observational study was carried out with children aged 1 to 12 years. The child’s behaviour before anesthesia was evaluated using the Pediatric Anesthesia Behavior (PAB) score. Medications used during the perioperative period were registered. The Watcha scale was used to evaluate if children developed ED and the Visual Analogue Scale (VAS) was used to register pain intensity during the first 15 minutes after the awakening. Parents of patients who experienced agitation were asked to assess their child’s behaviour two weeks after the anesthesia. Results: Among 136 observed patients 24 (17.6%) had ED. The duration of anesthesia among ED experienced patients was 45.42 (SD 18.35) min and it was significantly shorter than among children who didn’t develop ED – 60 (SD 29.03) min, p = 0.016. Eighteen (15.5%) patients in a mild pain group (VAS 0 to 3) experienced ED while in a moderate-25 severe pain group (VAS 4-10) there were 6 (37.5%) children who developed ED, p=0.033. However, age, the American Society of Anesthesiologists Classification (ASA) class, surgery type, behaviour before anesthesia induction and perioperative medications were not associated with ED. Conclusions: The prevalence of ED observed during our study, short duration of anesthesia and postoperative pain association with ED coincided with the results specified by other researchers. ED associated behavior changes were reported in the late postoperative period. Our other findings appeared to be not consistent with the results reported in other studies. Thus, the dilemma of ED still remains unresolved.

Surgical treatment of patients with nodular toxic goiter

Nodular toxic goiter (NTG) accounts for 7.3 % to 10.0 % of the goiter population. There are difficulties in the preoperative differential diagnosis between NTG and other thyroid diseases. There is also controversy about the benefits of resection surgery over thyroidectomy in patients with NTG. The aim of the study: a comparative assessment of the diagnosis and treatment results of patients with NTG in the early and late postoperative periods after resection surgery and thyroidectomy. Materials and methods. The study enrolled 51 patients with NTG. The mean age of patients in the group was 51.7 ± 12.9 years. Results. Bilateral multinodular lesions prevailed – 34 (66.7 %) patients. Free T3 level was measured only in 15 (29.4 %) patients, 7 (46.7 %) of them had elevated T3 level. 15 (29.4 %) patients underwent hemithyroidectomy including the isthmus, 2 (3.9 %) had subtotal resection, 34 (66.7 %) patients underwent thyroidectomy. Conclusions. Multinodular bilateral thyroid lesions dominated the structure of NTG – 34 (66.7 %) patients who underwent thyroidectomy. Uninodular and multinodular unilateral pathology was diagnosed only in 17 (33.3 %) patients who underwent organ-preserving surgery. The measurements of free T3 level in patients with NTG allowed the diagnosis of T3-thyrotoxicosis in almost half of patients (46.7 %), which is a diagnostic criterion for detection of functional nodal autonomy. Following the organ-preserving surgery, 17 (33.3 %) patients with NTG required the use of hormone replacement therapy with levothyroxine at a mean dose of 25.0 (25.0; 50.0) mcg/day in the late postoperative period (>1 year).

Clinical case of conservative treatment of choroid detachment that developed in the long term after phacoemulsification of age-related cataract

A clinical case of successful conservative treatment of choroidal detachment (CD), which developed in the long term after phacoemulsification of age-related cataract (PEC), is presented. The patient underwent PEC of the left eye 3 months ago with implantation of a posterior chamber intraocular lens, while an antiglaucoma operation was performed a year earlier. The patient was canceled the hypotensive regimen and conservative treatment was prescribed – instillation of Midrimax drops (Phenylephrine 5.0% + Tropicamide 0.8%) 2 times a day, Dexamethasone 0.1% – 4 times a day, subconjunctival injections of 2 mg Dexamethasone and 0.1 ml of 0.1% solution of Atropine sulfate. The prescribed conservative treatment made it possible to arrest the CD in the pseudophakic eye, which arose in the late postoperative period, and made it possible to avoid the need for posterior sclerectomy. Key words: choroid detachment, phacoemulsification of age-related cataract, conservative treatment.

Incidental Chylous Ascites Associated With Internal Hernial After Bariatric Surgery. Case Series

Bariatric surgery is of great importance due to the high incidence of morbid obesity. Techniques such as gastric bypass laparoscopic, tubular gastrectomy laparoscopic and other bariatric techniques with gastrointestinal anastomosis are used for its treatment. The incidence of internal hernias in the late postoperative period after bariatric surgery ranges from 0.4 to 8.8%. As a consequence, there may be obstruction of the lymphatic vessels. Although chylous ascites is a rare pathology in bariatric surgery, several cases have been reported in the literature. We present two cases of patients who presented as a late complication an internal hernia associated with chyloperitoneum.
