Errors leading to unexpected pseudophakic ametropia.

PURPOSE: Determination of the reasons for clinically significant unplanned ametropia following cataract surgery and the results of management of the ametropia. METHODS: Retrospective review of 11 consecutive cases of tertiary referral for management of pseudophakic ametropia to the authors. Corrective surgery involved either lens implant exchange or LASIK refractive surgery. Final outcome was assessed by uncorrected and best spectacle corrected visual acuity and manifest refractive outcome. RESULTS: Five cases (45%) were due to significant error in axial length determination at pre-surgery biometry. Six cases (55%) were due to surgeon or surgical team error, where the surgeon implanted a lens of power at variance with that specified pre-operatively. Nine patients elected to undergo refractive surgery to correct the ametropia and 2 elected to wear a spectacle lens. Seven underwent lens implant exchange and 2 patients underwent LASIK keratorefractive surgery. Eight of nine patients were within 1 dioptre of intended spherical equivalent after refractive surgery and 1 patients was -1.5 dioptre myopic. CONCLUSIONS: Most cases of serious unintended ametropia after cataract surgery are avoidable. Care should be taken with the biometry and procedural checks to minimise error. When lens implant exchange or LASIK was performed the final refractive results were satisfactory.

Pitfalls in the surgical management of cervical spine injuries.

Records of 69 cervical spine injury patients referred to the authors' institution over a 3-year period were reviewed. The senior author documented "definite" and "probable" pitfalls occurring in the pre-, intra-, and postoperative management. Diagnosis, traction, bracing, surgical timing, intraoperative technical errors, and incorrect surgical decisions were noted. Of the 69 patients, 39 (56%) suffered a pitfall of management. Twenty-seven patients (39%) accumulated 49 "definite" pitfalls between them and 12 patients (17%) suffered a total of 20 "probable" pitfalls. Of the 49 definite pitfalls, 7 (14%) were preoperative, 17 (34%) were those of surgical decision making, 21 (43%) were operative, and 4 (9%) postoperative. Diagnostic errors and incorrect bracing and traction led to neurological worsening. Intraoperatively, technical errors (30%), wrong timing of surgery (24%), and incorrect choice of operation (16%) were the common pitfalls. Postoperative pitfalls consisted of inappropriate bracing (17%). A Cervical Spine Research Society review (1989) rated complications of cervical spine surgery at 6.3% (63/992). In this study, a sizeable portion (56%) of cervical spine injury patients requiring surgery were at a risk of complications. Short of complications, there are areas of management where errors may have less well-documented undesirable effects or increase the potential for morbidity. An awareness of these pitfalls and increased use of non-operative treatment may eliminate up to 73% of the pitfalls and thereby decrease the morbidity associated with the management of cervical spine injuries.

Surgical skill is predicted by the ability to detect errors.

BACKGROUND: Objective analysis methods of surgical performance are now available so comparison between surgeons is available. One such method is by direct observation using the Objective Structured Assessment of Technical Skills (OSATS), but this is a time-consuming process; therefore, a simple screening tool for the ability to detect errors (previously validated) was analyzed and considered as a predictor of qualitative performance. METHODS: Thirty-eight volunteer surgeons were recruited to the skills laboratory to undertake 3 exercises. Two were bench-top surgical tasks that were scored using the global rating of the OSATS technique. The third task was the ability to detect simple errors in 22 synthetic models of common surgical procedures, some of which contained purposefully made errors. P<.05 was deemed to be statistically significant. RESULTS: The scores (interquartile ranges in parentheses) for the 3 sections were excision of sebaceous cyst=21 (19,24), closure of small bowel enterotomy=23 (21,27), and identification of errors=31 (27,34). Three scorers blinded to the operative models exhibited an interobserver reliability of .9 and .91 for the video tasks, respectively. Spearman's rank correlations between the error examination and performance on the 2 tasks were both statistically significant at .69 (cystectomy) and .54 (enterotomy). CONCLUSIONS: The ability to detect simple surgical errors is a predictor of technical skill and performance of bench tasks. What must be answered is whether the use of such models and principles can shorten the qualitative surgical learning curve.

[Enterocutaneous fistula in the pediatric population. Clinical experience].

BACKGROUND: The presence of fistulous communications between the small bowel and the skin continues to be one of the most perplexing and challenging problems facing the surgeon today. Their occurrence is a major catastophe of surgical practice because are frequently a result of technical failure or errors in surgical judgement. MATERIAL, METHOD AND RESULTS: Thirty four patients with high-output enterocutaneous fistulae arising from the small intestine are reported. Fourteen were due to appendicitis and sixteen were infants. Fistula resection were performed in six patients. Spontaneous fistula closure occurred in twenty-eight. Six died. The treatment program included parenteral nutritition thorugh central venous line, local care and antibiotics. CONCLUSIONS: In recent years, more aggressive therapy accompanied by the development of high caloric parenteral alimentation shows promise of reducing the mortality and morbidity rates associated with these fistulas.

Safe laparoscopic dissection of the gastroesophageal junction.

BACKGROUND: The laparoscopic approach to surgical diseases of the foregut is rapidly gaining acceptance. These new approaches, however, pit the unwary surgeon against potentially devastating complications. PATIENTS AND METHODS: Based on a retrospective review of 153 consecutive laparoscopic foregut surgeries performed at a designated laparoscopic center between August 1990 and June 1994, plus analysis of the records of 6 patients referred from outside our institution, we determined that the majority (15 of 16) of these complications were the result of violating one of five technical precepts: (1) safe use of esophageal dilators; (2) atraumatic retraction; (3) systematic dissection of the esophageal hiatus; (4) dissection under direct vision; and (5) use of appropriate suturing techniques. RESULTS: A retrospective review of our experience with laparoscopic gastroesophageal surgery shows an operative complication rate of 6.5%. The majority of these complications (7 of 10) were recognized at the time of occurrence and treated laparoscopically without subsequent complication. Two patients had delayed complications that required treatment. One patient developed adult respiratory distress syndrome, apparently not related to surgical technical error. The other patient required an additional laparoscopic surgery to correct a dissection error. This complication rate compares very favorably with those reported for open surgical techniques, that range from 14% to 22%. CONCLUSION: This report outlines surgical precepts that, if violated, could lead to iatrogenic injury, which could result in severe morbidity if not recognized or properly treated.

[Primary disability in patients with tuberculous spondylitis and the ways for its decrease].

Causes responsible for invalidity were analysed in 167 patients with a circumscribed form of tuberculous spondylitis. The causes were divided into 4 groups: diagnostic errors; errors in treatment; prognostic errors (late indications to surgical treatment); organizational errors. Heightening of the quality of early diagnosis of tuberculous spondylitis at a primary application to a medical institution and timely high-quality specific therapy in the antituberculous institutions will contribute to an increase in treatment effectiveness and invalidity reduction.
