Intestinal obstruction is one of the most common diseases in abdominal surgery, and its prevention and treatment is a clinical difficulty. Although surgical operation can solve the symptoms of obstruction, there are many postoperative complications, and it is easy to develop re-obstruction due to postoperative abdominal adhesion. The internal fixation of small intestine with obstruction catheter provides a new idea for the prevention of postoperative adhesive bowel obstruction. The use of transanal ileus catheter provides the possibility of direct intestinal anastomosis after resection of malignant obstruction in the left hemicolon and can reduce the incidence of postoperative complications. However, sufficient attention should be paid to the related complications, and prevention and treatment should be planned. It is important to note that the use of obstruction catheter is only one of the conservative treatments for bowel obstruction, and it is not a complete replacement of surgery. Surgical treatment should still be considered, if the catheter fails to significantly move, if the obstructive symptoms do not significantly improve 5 days after catheterization.

Post-operative adhesions are a common complication of pelvic and abdominal surgeries. Many approaches for preventing post-operative adhesions have been developed. This review summarizes the recent advances in this topic.

OBJECTIVEAdhesive or too highly located folds upper eyelid and even blepharoptosis are common complications of double eyelid operation. To correct such deformities.

METHODWe shifted down the double eyelid line, removed adhesion thoroughly, relieved orbital fat and restarted the volume with infraorbicularis oculi fat flap.

RESULTWe had treated 32 case in past two years. The results were satisfying.

CONCLUSIONThe method are acted easy and gained fine result, so behaving to extend application.

OBJECTIVETo evaluate the efficacy of cartilage tympanoplasty in the treatment of adhesive otitis media.

METHODSFrom June to October, 2008, 18 patients with adhesive otitis media (18 ears) were treated with tragus cartilage tympanoplasty. The air-bone gap changes and the self-perceived symptomatic improvement were evaluated at 1 month and 1 year after the operation.

RESULTSAll the patients showed dry ear within 6 weeks after the operation. Tympanic membrane healing was achieved in 17 cases, and 1 case presented with a inferior-anterior fissure in the tympanic membrane. With the average preoperative air-bone gap (at 0.25, 0.5, 1.0, and 2.0 kHz) of 44.65 dB, the patients showed an obvious decrease of the air-bone gap by over 10 dB at 1 month after the operation and by over 25 dB at one year. Symptomatic improvements were achieved in these cases, including alleviated ear discomforts (3/15 cases), total tinnitus relief (1/11 cases), and alleviated tinnitus (10/11 cases). High-frequency tinnitus was noted in 1 case (1/7 cases), and the tympanic membrane appeared normal in 17 cases.

CONCLUSIONTympanic membrane reconstruction using the tragus cartilage can be feasible for treatment of secretory otitis media, but the surgical indications should be carefully controlled.

OBJECTIVETo establish a rabbit double uterine horn model for assessing the time-course of pelvic adhesions and evaluating the effectiveness of different anti-adhesive materials in reducing adhesions.

METHODSA total of 330 Japanese white rabbits underwent laparotomy, followed by uterine horn incision. Animals were euthanized after 3, 7, 14, 28, and 42 days, respectively.

RESULTSThe surgical procedure was smooth. Rabbit double uterine horn model was applied for the evaluation of pelvic adhesions in a three-dimension fashion. Each of the three means-gauze abrasion, needle holder clamping, and direct uterine incision induced postoperative pelvic adhesions, among which direct uterine incision was the best to mimic conditions after gynecological operations. Under normal circumstances, degradation of filmy fibrinous adhesions by locally released proteases of the fibrinolytic system occurred within 3 days of injury. The regeneration of the mesothelium was completed within 7 days. Collagen reached its peak by day 14. Anti-adhesive materials were supposed to be completely absorbed by day 28, and their effectiveness in preventing pelvic adhesions was confirmed at this time point. Whether their effect can be maintained after the absorption of the anti-adhesive materials was investigated in 42 days.

CONCLUSIONSThe animal model was successfully established. It well mimics the postoperative pelvic adhesions after direct uterine horn injury and thus is a suitable model for studying site-specific adhesions. Observations on the 3rd, 7th, 14th, 28th, and 42nd post-operative days provided a full picture of the adhesion formation process.

BACKGROUNDTendon adhesion is one of the most common causes of disability following tendon surgery. Therefore, prevention of peritendinous adhesion after surgical repair of tendon is a major challenge. The aim of this study was to explore the possible application of a collagen membrane for the prevention or attenuation of peritendinous adhesions.

METHODSSprague-Dawley (SD) rat Achilles tendon was cut and sutured by a modified Kessler's technique with or without the collagen membrane wrapped. Macroscopic, morphological and biomechanical evaluations were applied to examine the recovery of the injured tendon at 4 and 8 weeks after surgery.

RESULTSThe surgery group wrapped by collagen membranes had a better outcome than the group with surgery repair only. In the collagen membrane-treated group, less adhesion appeared, stronger tensile strength was detected, and more tendon fibers and collagen I expression were observed morphologically.

CONCLUSIONWrapping the tendon with a collagen membrane may be an efficient approach for tendon repair and preventing tendon adhesion after its ruptures.

Hysteroscopic surgery is a minimally invasive procedure for the treatment of intrauterine pathologies. However, it can result in fatal complications. We herein report a case of symptomatic hyponatremia and hyperglycemia during hysteroscopic resection of severe intrauterine adhesion with 5% dextrose in water as the distension medium. Because of the difficulty of the incision, the infusion pressure was 100 to 150 mmHg, and surgery was continued for 70 minutes. A total of 19 L of 5% dextrose in water was used as an irrigating fluid. Large-scale absorption of irrigating fluid (3 L) induced dilutional hyponatremia (120 mmol/L) and hyperglycemia (30 mmol/L). Initial signs were abnormal flatulence and postoperative coma. Hypertonic saline, diuretics, insulin, and liquid restriction were the prevailing treatment strategies for hyponatremia and hyperglycemia. Ionized calcium and potassium levels decreased during treatment. We emphasize the importance of prevention, recognition, and a meticulous perioperative treatment standard. Surgical teams must be vigilant in fluid deficit monitoring and serum electrolyte analysis.

Postoperative epidural adhesion is one of the most common causes of failed back surgery syndrome (FBSS), which can lead to back and leg pain or neurological deficit. Prevention of epidural adhesion after laminectomy is critical for improving the outcomes of lumbar surgery. The main origins of epidural fibrosis are raw surface of erector muscles and rupture fibers of intervertebral disc. The main current preventive methods for epidural adhesion include the usage of implants, chemicals and low dose radiation. However, most of them are still in experiment period. There are still controversies on the clinic usage of autograft free fat, ADCON-L, and Mitomycin C (MMC). The optimal implants are characteristics of better biocompatibility, degradable absorption and capability of existing for a certain period in body. The optimal medicine should have good effect on anti-desmoplasia, less side effects and long half-life. Besides, the combination of biodegradable medical film and drug and the mixture of two or more medical films are also the research frontlines of epidural adhesion. Further researches are required to explore new materials and drugs with stable and most favorable effect in preventing epidural adhesion.
