Objective To observe the diameters of macular hole and destroyed boundary line between inner and outer segment (IS/OS) of the photoreceptors and the correlation with the visual acuity in patients with idiopathic macular hole(IMH). Methods The clinical data of 39 eyes (37 patients) with IMH were retrospective analyzed. All the patients had undergone the examinations of visual acuity (Snellen chart), intra-acular pressure, ocular fundus (indirect ophthalmoscope), and Fourier-domain optical coherence tomography (FD-OCT) whose speed was 27 000A scan/s, area was 6.0 mmtimes;6.0 mm, and the mode was 512times;128. The diametres of macular hole and destroyed IS/OS, and the correlations with visual acuity were detected. Results The mean logMAR was 0.99plusmn;0.44 (ranged from 0.15 to 2.00),the mean diameter of macular holes was (942.0plusmn;348.4) mu;m(ranged from 171 to 1491 mu;m), and the mean diameter of IS/OS disruption was (1870.3plusmn;673.2) mu;m(range from 463 to 3176 mu;m). There was a significant correlation among the diameter of the macular hole, the diameter of the IS/OS disruption, and logMAR in IMH (P＝0.038, 0.002, 0.000）. In eyes with closed macular hole after surgery, the logMAR and the diameter of the IS/OS disruption had a significant decrease. Conclusion Using FD-OCT the photoreceptor changes can be visualized in vivo. The abnormality in the ISOS boundary line appears to be involved for a much larger area beyond the macular hole itself, and persists there with small size even after the macular hole closure surgery.
ObjectiveTo discuss the indications of the nonoperative management for perforated peptic ulcer. MethodsClinical data of 145 patients with perforated peptic ulcer, aged below 70 years old, with first attack and onset timelt;12 h , admitted to our hospital between January 2002 and December 2009, were analyzed respectively. Patients who were negative for fluid of abdominopelvic cavity in ultrasound examination and leakage in watersoluble contrast examination received nonoperative management, otherwise underwent operation directly (If the patients were being on medication for the ulcer, they should also go directly to surgery). Non-operative patients were converted to operation if the symptom had not relieved during the first 12 h. When admitted , the APACHE Ⅱ score was calculated for all patients. ResultsSeventy-four and 71 patients underwent non-operative management and operation directly respectively. Sex, age, onset time, perforation site and so on were comparable between the two groups （Pgt;0.05）, while APACHE Ⅱ score over 8 was 25.7% and 76.1% respectively with significant difference (P=0000). In nonoperative group, 11 (149%) patients were converted to operation. The mortality (4.1% vs 9.8%, P=0.203), mobility (16.2% vs 25.3%, P=0.175), hospital stay 〔(11.4±2.5) d vs (11.3±1.3) d, P=0.447〕, and cost 〔(11 657.3±2 826.4) yuan vs (10 013.0±1 877.4) yuan, P=0.212〕 between two groups had also no significant difference. The mean APACHE Ⅱ score was significant different between the survivors and the dead (9.3 vs 20.2, P=0.000). APACHE Ⅱ score was positively related to mortality and morbility （r=0.98, P=0.000； r=0.52, P=0.000）. ConclusionsNon-operative management is a safe and effective way in selected patients with perforated peptic ulcer, such as APACHE Ⅱ score ≤8, negative for fluid of abdominopelvic cavity in ultrasound examination, and leakage in water-soluble contrast examination. APACHE Ⅱ score is an important factor in prognosis of these patients.
ObjectiveTo explore the early diagnosis and treatment of acute non-tumor perforation of the back wall of ascending colon. MethodsWe retrospectively analyzed the clinical data of 17 patients with acute non-tumor perforation of the back wall of ascending colon treated between July 2007 and April 2014 in our hospital. Among them, 8 patients who underwent perforation repair combined with abdominal cavity drainage were regarded as the experimental group, and the other 9 patients who underwent operation of right hemicolectomy (or ascending colon resection) were designated as the control group. Clinical indexes and biochemical indexes of both the two groups were compared and analyzed. ResultsAll patients were cured. The operation time[(74.20±12.45), (120.23±15.20) minutes; t=-3.224, P<0.001], the intraoperative blood loss[(40.24±12.20), (80.69±18.98) mL; t=-4.114, P<0.001], the postoperative anal exhaust[(75.62±6.56), (84.54±7.82) hours; t=1.108, P=0.037], the medical expenses[(18.2±5.7) thousand yuan, (26.5±8.3) thousand yuan; t=-5.556, P<0.001], and the hypersensitive C-reaction protein on the third day after operation[(89.45±8.98), (99.85±10.78) mg/L; t=-3.004, P=0.029] in the experimental group and the control group all had significant differences. There was no significant difference between the two groups in the hospital stay time[(9.80±3.16), (9.81±3.20) days; t=1.501, P=0.080]. There was one case of incision infection in the experimental group and one case of fat liquefaction of incision in the control group, and both of them were cured after treatment. ConclusionThe early abdominal sign of perforation of the back wall of ascending colon is not obvious, which can easily lead to misdiagnosis as acute appendicitis. Early diagnosis mainly depends on the clinical symptom, vital sign, blood routine examination and CT examination. Among them, CT findings of gaseous sign behind peritoneum is a definite diagnosis, and operation should be arranged as early as possible. Perforation repair combined with abdominal cavity drainage is preferred due to its advantages of being simple, saving time, less bleeding and lighter traumatic reaction.
ObjectiveTo analyze the surgical effect, postoperative complications and effects on the body inflammatory response of laparoscopic gastroduodenal perforation repair, and to further evaluate the efficacy of laparoscopic perforation repair. MethodsWe retrospectively analyzed the clinical data of 123 patients with gastroduodenal ulcer perforation treated between February 2010 and February 2015. Among the patients, 65 underwent laparoscopic gastroduodenal ulcer perforation repair (laparoscopic group), and 58 underwent routine open gastroduodenal ulcer perforation repair (open group). Then, we compared the surgical effects (average bleeding volume, ambulation time, postoperative ventilation time, postoperative hospital stay), postoperative complications (wound infection, wound dehiscence, gastroduodenal fistula, abdominal abscess, intestinal obstruction), inflammatory reaction[preoperative and 1, 3, 5-day postoperative white blood cells (WBC) count, peripheral blood procalcitonin (PCT), C-reactive protein (CRP)] between the two groups. ResultsPatients in both the two groups underwent the surgery successfully. No patients in the laparoscopic group were transferred to open surgery. Compared with the open surgery, surgical bleeding volume, ambulation time, anal exhaust time and postoperative hospital stay of the laparoscopic group were significantly different (P < 0.05). Postoperative complications rate of the laparoscopic group was significantly lower than that of the open group (P < 0.05). One and 3-day WBC, PCT and CRP after surgery increased obviously in both the two groups. The above three indicators on the fifth day after surgery were not significantly different from those before the surgery in the laparoscopic group (P > 0.05), while they were significantly different from those before the surgery in the open group (P < 0.05). ConclusionsCompared with open perforation repair, laparoscopic perforation repair surgery is superior for its better surgical effects, fewer postoperative complications and lighter inflammatory response. It is a safe, effective and minimally-invasive treatment for gastroduodenal perforation.
ObjectiveTo observe the clinical efficacy of vitrectomy combined with modified inverted internal limiting membrane (ILM) flap covering technique for complicated macular hole (MH).MethodsThis is a retrospective case series. Twenty-one eyes of 20 patients who underwent vitrectomy combined with modified inverted ILM flap covering technique were enrolled in this study. Among these eyes, 9 eyes were idiopathic MH (IMH), with the mean basal diameter of (1 188.3±155.1) μm, minimum diameter of (626.9±86.2) μm, logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity (BCVA) of 1.1±0.3; 2 eyes were MH with high myopia, with the mean basal diameter of (696.5±232.6) μm, minimum diameter of (259.0±69.3) μm, logMAR BCVA of 1.3; 5 eyes were high myopia MH with retinal detachment (RD), with the mean BCVA of 1.5±0.1; 3 eyes were rhegmatogenous RD (RRD) with MH, with the mean logMAR BCVA of 1.6; 2 eyes were MH after vitrectomy for RRD, with the mean basal diameter of (1 606.0±69.3) μm, minimum diameter of (909.0±387.5) μm, logMAR BCVA of 1.6. All patients received 23G or 25G vitrectomy after removal of posterior vitreous cortex intraoperatively. Indocyanine green staining assisted circle-wise ILM peeling was performed. ILM of diameter 1.5 disc-diameters around fovea was residual and loosened; perfluoronoctane assisted inverting superior or temporal residual ILM covering on macular hole. C3F8, gas or silicone oil tamponade was performed at the end. BCVA and hole closure were followed up for 1-4 months. C3F8, gas or silicone oil was tamponaded at the end. BCVA and hole closure were followed up for 1-4 months.ResultsMH of 21 eyes were closed after surgery. Nine IMH were closed at typeⅠ, with U shape closure in 7 eyes, V shape closure in 2 eyes. Two eyes of MH with high myopia, 3 eyes of RRD with MH, 2 eyes of MH after vitrectomy for RRD were closed at typeⅠ of U shape. Five eyes of high myopia MHRD including MH closure at typeⅠof U shape 3 eyes, typeⅡ of W shape 2 eyes. The mean logMAR BCVA of IMH, MH with high myopia, high myopia MHRD, RRD with MH, MH after vitrectomy for RRD eyes were 0.8±0.3, 0.9±0.2, 1.4±0.1, 0.7±0.3, 0.9±0.2, respectively. The mean postoperative logMAR BCVA in IMH eyes was improved compared preoperative one (P=0.02). There was no obvious change of pre-and postoperative logMAR BCVA in MH with high myopia, high myopia MHRD, RRD with MH, MH after vitrectomy for RRD eyes (P=0.18, 0.10, 0.11, 0.18).ConclusionVitrectomy combined with inverted ILM flap covering technique for complicated MH is an effective method to improve the success rate of MH closure and the visual function.
Objective To observe the efficacy of lamellar hole-associated epiretinal proliferation (LHEP) flap insertion and autologous blood for degenerative type lamellar macular hole (LMH). Methods Retrospective case review. Twenty-eight eyes of 28 patients with LMH were enrolled in this study. There were 2 males (2 eyes) and 26 females (26 eyes). Best corrected visual acuity (BCVA), medical optometry, slit-lamp biomicroscop, indirect ophthalmoscope, spectral domain optical coherence tomography, b-scan ultrasonography and axial length detection were performed on all patients. Logarithm of the minimum angle of resolution (logMAR) was used to calculate visual acuity. There were 10 eyes (35.7%) with degenerative type LMH (flap insertion group) and LHEP. There were 18 eyes (64.3%) with tractional type LMH (general group). The differences of BCVA, AL, horizontal hole diameter from retina and lens state between two groups were not significant (P＞0.05). The differences of horizontal hole diameter of internal limiting membrane (ILM), central foveal thickness (CFT) and integrity of ellipsoidal zone between two groups were significant (P＜0.05). LHEP flap insertion and autologous blood without ILM peeling were used in eyes of flap insertion group. Vitrectomy combined ILM peeling were used in eyes of general group. The follow-up was ranged from 3 to 14 months. The changes of CFT, central foveal form and logMAR BCVA were observed. Results At latest follow-up, the BCVA of flap insertion group and general group were 0.34±0.27, 0.31±0.29; which significantly better than the preoperative BCVA (Z=−3.519, −4.945; P＜0.001). The CFT of flap insertion group and general group were (200.10±58.78), (226.61±70.49) μm. There was no difference between pre- and post-operative CFT in eyes of general group (Z=−1.455, P=0.146). There was significant difference between pre- and post-operative CFT in eyes of flap insertion group (Z=−2.798, P=0.005). In flap insertion group, regular recovery of the foveal contour occurred in 9 eyes (90.0%), improvement in 1 eyes (10.0%). In general group, regular recovery of the foveal contour occurred in 10 eyes (55.6%), improvement in 8 eyes (44.4%). The closure rate of LMH were 100% both in two groups. Conclusion LHEP flap insertion and autologous blood is an effective treatment of degenerative type LMH.
