Peripartum hysterectomy clinical characteristics and outcomes- a hospital based retrospective audit study.

INTRODUCTION: The study aims to evaluate and report on the clinical characteristics, incidence, risk factors and associated complications of emergency and planned peripartum hysterectomy in a single training and research tertiary health care centre in Malaysia. MATERIALS AND METHODS: We conducted a 6-year retrospective cross-sectional study from the 1st January 2016 until 31st December 2021. Clinical, demographic characteristics, perioperative parameters, operative indications, blood loss, maternal/neonatal outcomes and complications were analysed. Patients were subdivided, analysed and studied in two subgroups- emergency hysterectomy (EH) and planned hysterectomy (PH). RESULTS: There were 65 cases of peripartum hysterectomy out of total 100,567 deliveries, with a prevalence rate of 0.06%. Overall, the majority of patients were multiparous (96.9%), having previous caesarean scar (73.8%) or diagnosed with placenta praevia (75.4%). More than half of the total patients (61.5%) have both previous caesarean scar and concomitant placenta praevia. EH was carried out in 39(60%) patients while 26(40%) patients underwent PH. The only indication for surgery in the PH group (100%) was abnormal placentation while the most common indication for surgery in the EH group (53.8%) was postpartum haemorrhage related to abnormal placentation. Patients who underwent EH were more likely to have massive blood loss (p=0.001), require ICU admissions (p=0.001), have DIVC cycles transfused (mean [SD] regime: 1.35 [0.95] vs 0.54 [0.99]; p=0.002), have lower postoperative haemoglobin level (mean [standard deviation, SD] haemoglobin: 9.23g/l [SD1.8] vs. 10.8 g/l [SD1.86]; p=0.001) and have higher difference between pre/post operative haemoglobin level (mean [SD] haemoglobin difference: 1.78g/l [SD6.34] vs 0.32g/l [SD1.7]; p=0.008) compared to patients with PH. Red blood cell transfusion, operating time, length of stay, weight of babies and Apgar score between two groups showed no significant differences. A significant reduction of blood loss between the first and the second half duration of the study (mean [SD] blood loss: 6978 ml [SD 4999.45] vs. 4100ml [SD2569.48]; p=0.004) was also observed. In the emergency group, 'non-placental cause' EH required significantly more red blood cell transfusion than 'placental cause' (p<0.05) while in the PH group, no significant difference was observed between the occlusive internal iliac artery 'balloon' and 'no balloon' subgroup in terms of operating time, total blood loss or blood transfusion. Overall complications showed more cases of post operative fever and relaparotomy in the EH group (18.4% vs. 7.6%) while urinary tract injuries including injuries to bladder and ureter occurred only in the PH group (9.4% vs. 0%). CONCLUSION: The majority of peripartum hysterectomy cases are due to placenta accreta spectrum disorders. Planned peripartum hysterectomies have a lower morbidity rate compared to emergency hysterectomies. Therefore, early identification of placenta accreta spectrum disorders and timely planning for elective procedures are crucial to minimise the need for emergency surgery.

Descemet's Membrane Endothelial Keratoplasty in South Asian Population.

PURPOSE: To evaluate visual outcomes, endothelial cell density and complications following Descemet's membrane endothelial keratoplasty (DMEK). METHODS: This study included 40 consecutive eyes that underwent DMEK for various pathologies involving the corneal endothelium. Best corrected visual acuity (BCVA) and endothelial cell density (ECD) were measured and compared before and 6 months after surgery. RESULTS: Out of 40 eyes, 34 eyes (85%) had BCVA ranging from 0.5 to 0.7 LogMAR 6 months postoperatively. Mean donor ECD was 2367.96 ± 47.87 (range, 2314.0-2472.0) cells/mm2 preoperatively, which was reduced to 1798.42 ± 45.79 (range, 1736.0-1902.0) cells/mm2 6 months after DMEK surgery, indicating a mean reduction of 569.54 cells/mm2 (24%) in ECD. CONCLUSION: DMEK is an emerging and a more advanced alternative to penetrating keratoplasty (PKP) and Descemet's stripping endothelial keratoplasty (DSEK) for corneal pathologies involving the corneal endothelium. Compared to PK and DSEK, however, DMEK has a longer learning curve, and its safety and efficacy need to be confirmed through more experience on a large volume of cases.

Descemet's Stripping Automated Endothelial Keratoplasty versus Descemet's Membrane Endothelial Keratoplasty in the Fellow Eye for Fuchs Endothelial Dystrophy: A Retrospective Study.

AIM: To evaluate visual outcome and endothelial cell density (ECD) after Descemet's Membrane Endothelial Keratoplasty (DMEK) in comparison with Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) in the fellow eye for Fuchs endothelial dystrophy (FED). DESIGN: Single-centre, retrospective case series. METHODS: 30 eyes of 30 patients undergoing DMEK, who completed a 1-year follow-up, were compared with 30 fellow eyes which underwent DSAEK for bilateral FED. Main outcome measures studied included Best Corrected Visual Acuity (BCVA) and ECD during a 1-year follow-up period. RESULTS: BCVA improved from 0.78 ± 0.35 logMAR, and 0.73 ± 0.31 logMAR before surgery to 0.22 ± 0.1 logMAR and 0.35 ± 0.12 logMAR 6 months after DMEK and DSEK, respectively (P < 0.001). At one year after surgery, the BCVA was maintained at 0.21 ± 0.12 logMAR and 0.34 ± 0.1 logMAR, respectively, after DMEK and DSAEK. A statistically better visual outcome was observed after DMEK compared to DSAEK (P < 0.05) in fellow eyes. CONCLUSIONS: DMEK provided better visual rehabilitation when compared to DSAEK. Nevertheless, there were no significant differences with regard to the ECD within a 1-year follow-up.

Implantable collamer lens V4b and V4c for correction of high myopia.

PURPOSE: To evaluate the visual outcome and intraocular pressure changes after Visian Implantable Collamer Lens (ICL) implantation V4b and V4c (with central hole) for correction of high myopia. METHODS: A prospective, consecutive, interventional comparative case series of V4b and V4c ICL implantation was done in high myopic patients who were unsuitable for laser vision. The main outcome measures studied were uncorrected and corrected distant visual acuity (UDVA, CDVA), ICL vault, intraocular pressure (IOP), endothelial cell count (ECC), and development of subcapsular lens opacities. The patients were evaluated at postoperative 1,3,6, and 9 months. RESULTS: A total of 62 eyes of 32 patients (24.56 ± 4.8 years) underwent V4b ICL implantation (21 non-toric, 41 toric ICL-TICL) with intraoperative peripheral iridectomy (PI), and 10 eyes of 5 patients (26.13 ± 3.8 years) had implantation of V4c ICL (4 non-toric, 6 TICL). The mean preoperative manifest spherical equivalent (MSE) was -9.98 ± 2.8 D and -9.14 ± 2.4 D in the V4b and V4c groups, respectively, which reduced to postoperative values of -0.24 ± 1.3 D and -0.2 ± 1.18 D, respectively. At the end of 9 months follow-up, mean ECC loss was 6.4% and 6.1%, mean vault was 573.13 ± 241.13 µ, and 612 ± 251.14 µ, respectively, in the V4b and V4c groups. Anterior subcapsular opacities were present in 6.9% and 3.14% of eyes with V4b and V4c groups, respectively. Four eyes from V4b (9.75%) and 1 eye from V4c (16.66%) had rotation of more than 30° and required realignment surgery, which was done successfully. Two eyes (3.22%) with V4b ICL implantation had high postoperative IOP (>35 mm Hg) due to blocked PI and required Nd:Yag laser iridotomy, which was done with successful control of IOP. The safety indices were 1.11 and 1.14, and efficacy indices were 1.4 and 1.5 in the V4b and V4c groups, respectively, at the end of 9 months. CONCLUSION: ICL implantation is a safe and effective surgery for correction of high myopia. Implantation of ICL with a central hole showed negligible postoperative IOP fluctuations without a peripheral iridectomy.

Nasal lobular capillary hemangioma.

Nasal lobular capillary hemangioma is a rare benign tumor of the paranasal sinuses. This lesion is believed to grow rapidly in size over time. The exact etiopathogenesis is still a dilemma. We discuss a case of nasal lobular capillary hemangioma presenting with a history of epistaxis. Contrast enhanced computed tomography of paranasal sinuses revealed an intensely enhancing soft-tissue mass in the left nasal cavity and left middle and inferior meati with no obvious bony remodeling or destruction. We present imaging and pathologic features of nasal lobular capillary hemangioma and differentiate it from other entities like nasal angiofibroma.

Mixed adenoneuroendocrine carcinoma of cecum: a rare entity.

Mixed adenoneuroendocrine carcinoma of cecum (MANEC) was first reported by Cardier in 1924. These tumors are thought to arise from multi-potential stem cells, which have differentiated bidirectionally. Location of the tumor influences the treatment and outcome. We report a rare case of MANEC where the patient presented with abdominal pain and distension. Imaging revealed an ileo colic intussusception with the lead point being a MANEC.
