Subbrachial approach to humeral shaft fractures: new surgical technique and retrospective case series study

BACKGROUND

There are few surgical approaches for treating humeral shaft fractures. Here we present our results using a subbrachial approach.

METHODS

We conducted a retrospective case series involving patients who had surgery for a humeral shaft fracture between January 1994 and January 2008. We divided patients into 4 groups based on the surgical approach (anterior, anterolateral, posterior, subbrachial). In all patients, an AO 4.5 mm dynamic compression plate was used.

RESULTS

During our study period, 280 patients aged 30-36 years underwent surgery for a humeral shaft fracture. The average duration of surgery was shortest using the subbrachial approach (40 min). The average loss of muscle strength was 40% for the anterolateral, 48% for the posterior, 42% for the anterior and 20% for the subbrachial approaches. The average loss of tension in the brachialis muscle after 4 months was 61% for the anterolateral, 48% for the anterior and 11% for the subbrachial approaches. Sixteen patients in the anterolateral and anterior groups and 6 patients in the posterior group experienced intraoperative lesions of the radial nerve. No postoperative complications were observed in the subbrachial group.

CONCLUSION

The subbrachial approach is practical and effective. The average duration of the surgery is shortened by half, loss of the muscle strength is minimal, and patients can resume everyday activities within 4 months. No patients in the subbrachial group experienced injuries to the radial or musculocutaneous nerves.

Estrogen replacement therapy improves pulmonary function in postmenopausal women with genital prolapse

OBJECTIVE

This study examined the impact of estrogen replacement therapy with spirometry on pulmonary function in surgically castrated (salpingo-oophorectomy) postmenopausal women with genital prolapse.

METHODS

The study included 60 postmenopausal women with pelvic organ prolapse. The study received institutional Ethics Committee approval, and all subjects signed an informed consent. Women were randomly divided into two groups of 30 subjects: Group 1 (n=30) was administered estrogen replacement with 1 mg of stradiol hemihydrate (1 mg/day) orally for 6 months, and group 2 (n=30) was not taking estrogen. Both groups were matched by age, height, body mass index, parity, and duration of postmenopause. All subjects were evaluated with spirometry initially and after 6 months. For statistical analysis, descriptive and analytical methods were used, based on data type and distribution. The mean and standard deviations were used as measures of central tendency and variability. Categorical data were expressed as absolute and relative numbers (percentage). The t-test for independent samples (for comparison of groups) and t-test for dependent samples (for comparison of serial measurements in the same patients) were used. The analysis was performed using R software ( www.r-project.org ), with the level of significance set at p<0.05.

RESULTS

Analysis of spirometry parameters showed statistically significant differences between the estrogen users and the nonusers groups.

CONCLUSION

The most important study result was the significantly improved lung respiratory function in postmenopausal women with genital prolapse after 6 months of taking estrogen, confirming that hormone replacement therapy should be recommended to postmenopausal women. The findings of our study suggest the need for further research into the effect of estrogen on pulmonary function.

Successful conservative and endoscopic treatment of pancreatic fistula due to splenectomy following blunt abdominal trauma

Pancreatic fistula most commonly occur as a consequence of resective procedures and pseudocyst drainage, and rarely as a consequence of splenectomy. Conservative treatment can have good results, but it is long lasting and demands long hospitalization. In case of conservative treatment failure, operative treatment is indicated, but this has significantly higher percentage of morbidity and mortality. In selected cases, conservative treatment with somatostatine or octreotide, along with endoscopic procedure including the use of fibrin glue, significantly accelerates sanation of the fistula and reduces the length of hospitalization. We report a case of exterior pancreatic fistula due to splenectomy following blunt abdominal trauma, which were successfully treated with conservative (infusion, antibiotics, enteral nutrition, and octreotide) and endoscopic therapy. During ERCP papillotomy was performed, and good external drainage using drainage catheter was important in the patient outcome. Considering the initial secretion of 300 mL/24 h, our patient had a high output fistula. Despite that, fistula was quickly resolved after treatment. Our opinion is that octreotide therapy and unobstructed drainage of pancreatic duct into the duodenum were the most important in the rapid resolution of the fistula.

Colonic lipoma intussusception: a case report

Lipomas are the most common mesenchymal benign tumor of the colon. They are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain. The diagnosis can be made by colonoscopy, barium enema examination, and by computed tomography (CT). We have reported a case of large submucosal lipoma of the ascending colon with intestinal obstruction. At laparotomy there was an intussusception descending colon, and subtotal colectomy was performed.
