[Abstract]Acute cardiac tamponade after thoracoscopic lobectomy is extremely rare and highly lethal once it occurs. This paper reports a case of a 64-year-old male with preoperative hypertension and coronary heart disease who underwent video-assisted thoracoscopic right upper lung wedge resection for early-stage lung adenocarcinoma. Three hours postoperatively, he suddenly developed hypotension and loss of consciousness. Ultrasound indicated a large amount of pericardial effusion, suggesting cardiac tamponade. Despite emergency pericardiocentesis, his hemodynamics did not improve, and the patient went into cardiac arrest. Subsequent veno-arterial extracorporeal membrane oxygenation was performed to support systemic circulation, and emergency thoracotomy was carried out. During the surgery, a needle-like tear in the anterior wall of the ascending aorta was found, corresponding exactly to a prominent staple at the lung resection margin, suggesting a stapler malfunction. After vascular repair, the patient recovered smoothly and was discharged. This case suggests that during lung resection, great attention should be paid to the integrity of staples and anatomical variations of large vessels, and vigilance is needed for rare but potentially fatal stapler-related complications.
ObjectiveTo observe the effect of modified ligation of intersphincteric fistula tract (LIFT) combined with acellular anal fistula repair matrix packing in the treatment of high anal fistula, and to evaluate its clinical efficacy and safety.MethodsAll 86 patients who met the diagnostic criteria of high anal fistula in Beijing Anorectal Hospital from October 2018 to August 2019 were selected and randomly divided into observation group and control group. The observation group was treated with modified LIFT combined with acellular anal fistula repair matrix tamponade, while the control group was treated with traditional low incision and high thread drawing surgery. The curative effect, wound healing time, postoperative pain score, intraoperative blood loss, postoperative complications, hospitalization time, patient satisfaction and recurrence at 6 months after operation were compared between the two groups.ResultsThe effective rate of the observation group was 92.9% (39/42), and that of the control group was 86.4% (38/44), there was no significant difference between the two groups (Z=?1.251, P=0.211). The healing time of the observation group and the control group were (24.8±8.5) days and (32.1±10.9) days, respectively, the difference was statistically significant (t=3.472, P<0.001). Compared with the control group, the observation group had less intraoperative blood loss, less postoperative pain and shorter hospital stay (P<0.05). There was no anal incontinence after operation in the two groups, and the incidence of postoperative complications such as bloody stool, anal border edema and urinary retention were lower in the observation group (11.9%) compared with the control group (31.8%), with a statistically significant difference (P<0.05). The treatment satisfaction of the observation group was 90.5%, and that of the control group was 81.8%. There was no significant difference between the two groups (Z=?1.284, P>0.05).ConclusionModified LIFT combined with acellular anal fistula repair matrix in the treatment of high anal fistula has the advantages of small trauma, quick recovery and low incidence of complications.
ObjectiveTo compare the efficacy of internal limiting membrane (ILM) flip coverage with ILM multilayer tamponade in the treatment of highly myopic macular hole-associated retinal detachment (MHRD). MethodsA retrospective clinical study. From November 2019 to June 2022, 53 cases and 53 eyes of MHRD patients who were examined and diagnosed at the Eye Centre of Renmin Hospital of Wuhan University were included in the study. Among them, 21 cases and 21 eyes were male and 32 cases and 32 eyes were female. The age was (55.28±11.40) years. The patients were categorized into two groups: the ILM coverage group (from November 2019 to September 2020) and the ILM multilayer tamponade group (from October 2020 to June 2022) based on their surgical procedures. The ILM coverage group comprised of 11 cases involving 11 eyes, while the ILM multilayer tamponade group comprised of 42 cases involving 42 eyes. Best-corrected visual acuity (BCVA) and optical coherence tomography were conducted. BCVA was measured using standardized international visual acuity charts and transformed to logarithmic minimum angle of resolution (logMAR) visual acuity for statistical analysis. The affected eyes were all treated with standard transciliary flattening three-channel 23-gauge vitrectomy. The inverted ILM flap technique was combined with flap coverage in the inverted group, while the ILM multilayer tamponade group used circular ILM stripping to preserve the ILM in the macular area and ILM flap around the macular hole with multilayer ILM tamponade. Postoperative follow-up was carried out for a minimum of 6 months. Relevant examinations were conducted during the follow-up using the same equipment and methods as those used before surgery. The BCVA, as well as the closure of macular hole, resurfacing of the retina, and development of macular hyperplasia, were observed. ResultsIn the ILM-covered group, the macular hole was closed in 7 out of 11 eyes after 1 week of surgery. At 1 month after surgery, the macular hole was closed in all treated eyes. At 6 months after surgery, the macular hole was closed in 9 eyes, while 2 eyes were reopened. In 42 eyes from the ILM-multilayer tamponade group, the macular hole closed after surgery in 41 eyes. At 6 months postoperatively, best corrected visual acuity (BCVA) of eyes in ILM-covered and ILM-multilayer tamponade groups was 0.91±0.29 and 1.05±0.39, respectively, with no statistically significant difference between the two groups (t=1.140, P=0.260). The BCVA of the eyes in both groups showed a significant improvement compared to the preoperative period with a statistically significant difference (t=8.490, 13.840; P＜0.000 1); 6 months after surgery, 10 out of 11 eyes in the ILM coverage group had a restored retina with no detectable macular hyperplasia; 42 eyes in the ILM multilayer tamponade group had a restored retina, but 19 of these eyes had detectable macular hyperplasia. ConclusionsEither ILM flap coverage or ILM multilayer tamponade contributes to high myopic MHRD closure and improved visual acuity. Compared to ILM flap coverage, ILM multilayer tamponade results in higher and earlier rates of macular hole closure and lower rates of macular hole reopening. However, ILM multilayer tamponade may lead to a higher proportion of macular hyperplasia formation without affecting visual acuity recovery at 6 months after surgery.
