External versus Endoscopic Dacryocystorhinostomy for Primary Acquired Nasolacrimal Duct Obstruction.

PURPOSE: The purpose of the study is to compare the surgical outcomes and success rates of external dacryocystorhinostomy (EX-DCR) versus endoscopic endonasal DCR (EN-DCR) for the treatment of primary acquired nasolacrimal duct obstruction (PANDO). METHODS: This retrospective nonrandomized study was conducted at Farabi Eye Hospital and Noor Eye Hospital, Iran. A review of electronic medical records of all patients with PANDO who underwent EX-DCR or EN-DCR between January 2016 and 2018 was carried out. RESULTS: A total of 803 patients underwent surgery, of which 618 patients (77%) were managed by EX-DCR and 185 patients (23%) by EN-DCR. The majority of cases (62%) were female. The mean age of the patients in EX-DCR and EN-DCR groups was 40.8 ± 14.2 and 34.3 ± 9.2 years, respectively. EX-DCR resulted in significantly less amount of pain compared to EN-DCR (P < 0.05). The success rate of surgery among EX-DCR and EN-DCR groups was 92.4% and 91.1%, respectively, and did not show statistically significant difference. A higher incidence of intraoperative hemorrhage requiring intervention was noted in the EN-DCR group (16.7% vs. 4.5%). Postoperative patient's satisfaction with EN-DCR and EX-DCR was 73% and 82%, respectively. CONCLUSION: Both EX-DXR and endoscopic DCR surgeries have high success rates and low incidence of failure. The choice of DCR technique should be based on the experience of the surgeon and patient's lacrimal and nasal anatomy and preferences.

Long-term outcomes of patients undergoing war-related amputations of the foot and ankle.

Long-term clinical and functional outcomes for patients undergoing foot and ankle amputations are not well documented. We attempted to document long-term outcomes for patients who required lower extremity amputations as a result of wounds suffered during wartime. For this study, 27 Iranian soldiers who had wounds requiring amputation of the foot and ankle were selected for follow-up. The participants' wartime medical records were reviewed, a clinical examination was performed, and each participant completed a questionnaire. Postamputation follow-up averaged 17.5 years. The most prevalent (66.6%) cause of injury was a land mine. The prevalences of different clinical symptoms reported by the amputees at the time of the last follow-up were as follows: 11 (40.7%) with phantom sensation, 6 (22.2%) with phantom pain, 12 (44.4%) with stump pain, 12 (44.4%) with back pain, 9 (33.3%) with contralateral knee pain, and 4 (14.8%) with ipsilateral knee pain; 20 (74%) reported treatment for psychological conditions. In regard to social conditions, 13 (48.1) were currently employed, or had been employed, for a number of years after the amputation; 26 (96%) had children, and all of the patients were married. The results of this observational study indicate that individuals have significant long-term pain and discomfort after war-related lower extremity amputation. Although all 27 (100%) of the amputees were able to maintain satisfactory family functioning, only 13 (48.1%) of the study participants were able to remain productively employed after undergoing amputation, and 20 (74%) reported long-term psychological problems in addition to their physical pain.
