The aim of this study was to report on the feasibility of setting up a system of corneal transplants at rural outreach centers and report the outcomes of the first 111 cases.

Retrospective analysis of the outcomes of corneal transplantation performed on patients with optical indications between March 2016 and September 2019 at 4 secondary (rural) centers. The centers are a part of a network in the pyramidal model developed by L V Prasad Eye Institute. The graft clarity and best-corrected visual acuity (BCVA) at 1-year follow-up were analyzed.

Of the 111 patients, 34.23% underwent penetrating keratoplasty and 65.77% endothelial keratoplasty. The mean age was 59.4 ± 15.0 (range-17-86 years); 47.75% were men and 52.25% were women. The indications for surgery were bullous keratopathy (54.05%), corneal scar/adherent leukoma (23.42%), and repeat grafts (13.51%). At the end of 1 year, 69.37% grafts remained clear. Factors associated with graft failure included poor socioeconomic status and graft infiltrate in both univariate and multivariate analyses. Surgical technique of endothelial keratoplasty was associated with failure on multivariate analysis only. Of the 77 eyes with clear corneal grafts at 1 year, the preoperative mean logMAR BCVA was 1.91 ± 0.06, which improved to 0.90 ± 0.08 postoperatively. Overall, 84.4% had preoperative BCVA of <3/60. Postoperatively, 40% had BCVA of 6/18 or better.

Our study showed that close to 70% grafts remained clear at 1 year. Graft failure was associated with poor socioeconomic status and graft infiltrates. This study established a viable model for delivery of corneal transplant surgery and care in a rural setup.

The purpose of this study was to describe a rare complication of Descemet membrane endothelial keratoplasty (DMEK) rebubbling.

An 86-year-old woman with bilateral penetrating keratoplasty (PK) performed 20 years previously for Fuchs endothelial dystrophy underwent DMEK surgery for endothelial corneal decompensation in the left eye. Surgery was complicated in the postoperative period by repeated DMEK graft detachments requiring rebubbling.

The third rebubbling procedure caused a traumatic PK wound dehiscence at the graft-host junction with full-thickness opening of approximately 180 degrees. PK wound dehiscence was resutured in the theater, DMEK lenticule was removed from the eye, and the full-thickness graft was repeated.

DMEK graft rebubbling in patients with previous PK may lead to traumatic wound dehiscence. Avoidance of excessive increases in intraocular pressure during the rebubbling procedure should be encouraged to decrease the risk of this rare complication.

This study was to report the outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) in managing corneal endothelial disorders in children less than 14 years of age.

Medical records of 180 DSAEK performed, between 2008 and 2020, on 167 eyes of 111 children who had a visually significant endothelial dysfunction were retrospectively reviewed for the primary etiology of corneal decompensation, time of the onset and duration of cloudiness, preoperative visual acuity, the technique of endothelial keratoplasty, surgical modifications, and reintervention.

Median age at surgical intervention was 7.9 years (interquartile range, 5.2-11.2 years). At a median postinterventional follow-up of 2.5 years (interquartile range, 0.9-3.4 years), 86.2% (144 of 167 eyes, 95% confidence interval 79.9%-90.1%) maintained a clear graft. Median best-corrected visual acuity (logarithm of the minimum angle of resolution) improved from 1.45 ± 0.70 preoperatively to 0.90 ± 0.06 at the last follow-up visit (P < 0.0001). The cumulative overall long-term graft survival was 92.7%, 86.5%, and 77.7% at 1, 3, and 7 years, respectively. Cox proportional hazards regression analysis showed that the indication for DSAEK (P = 0.007; hazards ratio 2.17 ± 0.62), age at surgery (P = 0.02; hazards ratio 0.87 ± 0.05), and any subsequent intervention after DSAEK (P = 0.003; hazards ratio 0.11 ± 0.08) were significant risk factors for DSAEK failure. The endothelial cell loss was 40.1% at 6 months, 45.4% at 1 year, 55.2% at 5 years, and 61.9% at 7 years.

DSAEK is a safe and effective surgical strategy in managing endothelial disorders among the pediatric age group.

Performing ablative surgery using an laparoscope is a common practice. However, its use in the harvest of a segment of intestine for reconstruction has 2 major challenges risk of damage to the vascular pedicle of the flap as well as to the vessels of other parts of the intestine that remain in the peritoneal cavity and risk of damage to the intestinal flap while pulling it out through a small opening in the abdominal wall. The aim of this study was to report advantages and disadvantages of harvesting free intestinal flaps using the laparoscopic method, explaining the challenges faced and lessons learned from this experience.

Free intestinal flaps were harvested by laparoscopy in 12 patients aged 28 to 63 years. There were 9 free jejunal flaps for the reconstruction of the cervical esophagus and 3 ileocolic flaps for the reconstruction of both the cervical esophagus and voice reconstruction.

In 1 patient, laparoscopy was converted to laparotomy due to previous colectomy, which resulted in compromised cirlaps by laparoscopy.

Laparoscopic surgery aims at reducing wound complications and improving cosmetics, among other advantages. High rates of postoperative ventral hernia (POVH) are observed after laparoscopic-assisted colectomies.

In a 2011 to 2016 retrospective study of all patients at Rabin Medical Center, we examined POVH prevalence after right hemicolectomy for neoplasia and correlation to specimen extraction site. We also compared laparoscopic-assisted colectomy to hand-assisted laparoscopic colectomy. selleck Included were patients who had postoperative abdominal computed tomography or magnetic resonance imaging scan as part of their routine oncological follow-up to 6 months postsurgery. Patients were excluded for conversion to laparotomy, and prior abdominal surgeries after right colectomy and before follow-up computed tomography/magnetic resonance imaging scan. Demographic and surgical data were collected from patient electronic records, and scans reviewed for POVH by a designated radiologist.

Of 370 patients, 138 (mean age 70.09 y, 58 males) were included 54 (39.1%) were diagnosed with POVH, 42/72 (58.3%) at midline extraction site, and 12/66 (18.8%) at off-midline extraction sites (P<0.0001). Surgical site infections and patients positive for tumor metastasis were associated with higher POVH rates. Most (74%) POVHs were identified within 18 months postsurgery (P<0.0001). Body mass index, age, sex, diabetes mellitus, smoking, tumor size, lymph nodes positive for metastasis, and hand-assisted laparoscopic colectomy were not associated with POVH prevalence.

High rates of radiologically diagnosed POVH were found after laparoscopic-assisted colectomy, with association to midline extraction site, surgical site infections, and positive tumor distant metastasis.

The coronavirus 2019 pandemic and the hypothetical risk of virus transmission through aerosolized CO2 or surgical smoke produced during minimally invasive surgery (MIS) procedures have prompted societies to issue recommendations on measures to reduce this risk. The aim of this systematic review is to identify, summarize and critically appraise recommendations from surgical societies on intraoperative measures to reduce the risk of severe acute respiratory syndrome coronavirus 2 transmission to the operative room (OR) staff during MIS.

Medline, Embase, and Google Scholar databases were searched using a search strategy or free terms. The search was supplemented with searches of additional relevant records on coronavirus 2019 resource websites from Surgical Associations and Societies. Recommendations published by surgical societies that reported on the intraoperative methods to reduce the risk of severe acute respiratory syndrome coronavirus 2 transmission to the OR staff during MIS were also reviewed for inendations shifted to encouraging the use of MIS as long as adequate precautions could be taken to protect the safety of the OR staff. The release and implementation of recommendations should be based on evidence-based practices that allows health care systems to provide safe surgical and medical assistance.

While some of the early recommendations advised against the use of MIS, they were not strictly based on the available scientific evidence. After further consideration of the literature and of the well-known benefits of laparoscopy to the patient, later recommendations shifted to encouraging the use of MIS as long as adequate precautions could be taken to protect the safety of the OR staff. The release and implementation of recommendations should be based on evidence-based practices that allows health care systems to provide safe surgical and medical assistance.

To provide the most recent insights in the use of biologicals in the treatment of patients with anaphylaxis.

There is evidence that biologics such as omalizumab may be safe and effective in preventing anaphylactic reactions in patients at high risk mainly because of severe food allergy or desensitization procedures to food, airborne allergen, drugs, or hymenoptera venom.

Further knowledge will guide the adoption and implementation of any new therapy including biologics for anaphylaxis according to the stratification of risk/benefits.
