Objective To explore the clinical significance on protection of parathyroid and recurrent laryngeal nerve (RLN) by meticulous capsular dissection and exposure of RLN in thyroid lobectomy. Methods Clinical data of 452 patients who underwent thyroid lobectomy by meticulous capsular dissection and exposure of RLN in our hospital from Jan. 2010 to Dec. 2012 were retrospectively analyzed. Results All of the 452 cases underwent thyroid lebectomy successfully without death, and the operative time was 45-110min (average 60 min), the blood loss was 5-100mL (average 20mL). The pathological results showed that there were thyroid adenoma in 193 cases, nodular goiter in 175 cases, Hashimoto thyroiditis in 38 cases, thyroid cancer in 46 cases. After operation, 4 cases suffered RLN injury, 1 of the 4 cases recovered after removal of drainage tube, and other 3 cases recovered during 0.5 to 3.0 months. In addition, 2 cases suffered laryngeal nerve injury whose symptoms disappearred within 1 week, 5 cases suffered parathyroid founctional damage without permanent hypocalcemia whose symptom had kept 1-5 days after treatment. Three cases were reoperated because of bleeding, including branch of anterior venous bleeding in 1 case, thyroid side arterial tube bleeding in 1 case, and thyroid stump bleeding in 1 case. Twenty one cases suffered hypothyroidism in 1 month after operation, and no recurrence happened during the followed up period. Conclusions Meticulous capsular dissection can effectively protect function of parathyroid and reduce the injury probability of RLN. Exposure of RLN is safe and feasible, which plays an important role in avoiding serious RLN injury.
ObjectiveTo explore various exposure technology of gastroesophageal region and their advantages and disadvantages by laparoscopic surgery in upper abdominal. MethodThe related literatures on various exposure technology of gastroesophageal region by laparoscopic surgery in upper abdominal at home and abroad in recent years were collected and reviewed. ResultsNow, there were main three exposure technologies of gastroesophageal region by laparoscopic surgery in upper abdominal, including traditional retractor liver retraction, suspension liver retraction, and adhesion liver retraction. Each method had its own advantages and disadvantages. Conclusionthe most suitable exposure method of gastroesophageal region by laparoscopic surgery in upper abdominal should be selected according to situations of surgery and patient.
ObjectiveTo explore the feasibil ity and rel iabil ity of rib-sparing technique for internal mammary vessels exposure and anastomosis in breast reconstruction and thoracic wall repair with deep inferior epigastric perforator (DIEP) flaps. MethodsBetween November 2009 and September 2011, 11 female patients with post-mastectomy deformities were treated. The mean age was 42 years (range, 33-65 years). Of them, 10 patients underwent breast reconstruction with the DIEP flaps, and 1 patient received defect repair for chronic thoracic wall irradiated ulcer with the DIEP flap. The size of the flap ranged from 18 cm×9 cm to 28 cm×12 cm. Rib-sparing technique was applied in all these cases. The internal mammary vessels were exposed by dissection intercostal space and anastomosed with the deep inferior epigastric vessels. The donor sites were closed directly in all cases. ResultsIn all cases, the rib-sparing technique for internal mammary vessels exposure and anastomosis was successfully performed. The mean time for internal mammary vessels exposure was 52 minutes (range, 38-65 minutes). The mean exposure length of the internal mammary vessels was 1.7 cm (range, 1.3-2.2 cm). All flaps survived completely postoperatively, and wounds and incisions at donor sites healed primarily. All patients were followed up 8-26 months (mean, 12 months). All patients were satisfied with the reconstructive outcomes. No collapse deformity or discomfort of the thoracic wall occurred. ConclusionThe rib-sparing technique for internal mammary vessels exposure and anastomosis is a rel iable and reproducible approach to reconstruct the breast and repair the thoracic wall with DIEP flap, and it can reduce collapse deformity of the thoracic wall.
