Open rhinoplasty for treatment of nasal tip haemangioma

Haemangiomas are the most common tumours of infancy. They typically proliferate then involute with considerable variation as regards to their rates of proliferation and involution. Haemangioma of the nasal tip is a lesion of special characteristics. During proliferation, it expands, contracts and deviates the nasal cartilages. Particularly, it regresses slowly and frequently involutes incompletely. That is why excision of the lesion is frequently suggested. The present study was conducted to evaluate open rhinoplasty after initial non-excision treatment modalities namely, intra-lesional corticosteroid injections and laser treatment, as a protocol of treatment for nasal tip haemangiomas. Twelve patients with nasal tip haemangiomas were included in the present study. Patients of both sexes, of different ages, with deep and mixed haemangiomas were studied. Disfigurement was the constant presenting symptom. Initial non-excision treatment reported different responses as denoted by the regression of the lesions’ size. Haemangiomas constantly extended between the medial crura of the alar cartilages as noted by the constant widening of the columella pre-operatively and the obvious separation of the nasal cartilages intra-operatively. This separation was constantly found to require approximation by sutures. The results of the present study concluded that whenever an early presentation with nasal tip haemangioma could be established, initial non-excision treatment followed by open rhinoplasty could be a useful protocol of treatment. Within the limitations of the present study, this protocol could achieve an early, safe and effective treatment for nasal tip haemangiomas with provisionally acceptable cosmetic outcomes so far.

腹腔镜胆囊切除术不同压力CO2气腹对气腹存留时限及肩部疼痛的影响

目的 探讨腹腔镜胆囊切除术(laparoscopic cholecystectomy,LC)不同压力CO2气腹对气腹存留时限及肩部疼痛的影响,探讨LC术后气腹存留时限的影响因素及肩部疼痛的原因.方法 2002年4～10月连续观察69例LC,随机分为A、B、C 3组,每组23例.气腹压力设定A组10mm Hg,B组12mm Hg,C组14mm Hg.对69例LC术后进行连续胸部X线平片观察膈下游离气体,测量术后24h两侧膈下游离气体的长、高并计算残气量.采用视觉模拟评分(vision analogue score,VAS)观察3组术后1、3、6、12、24、48、72、96、120h肩部疼痛程度.结果 LC后气腹存留时限为(1.8±1.1)d,男女组气腹存留时限分别为(1.8±1.1)d和(1.7±1.0)d,2组比较无显著意义(H=0.013,P=0.911).3组术后24h膈下残气量及术后气腹存留时限差异无显著性(P＞0.05).逐步回归分析示lg(气腹存留时限)与术后24h膈下残气量呈正相关(r=0.616,P=0.006),与气腹时间呈负相关(r=-0.228,P=0.014),与年龄、体重、身高、手术时间及所用气体量无相关性.术后26例出现肩部疼痛,随着A、B、C 3组气腹压力的增高,发生肩部疼痛患者的VAS评分明显增高(F=9.635, P=0.000),术后24h肩部疼痛VAS评分与术后24 h右侧膈下残气量呈正相关(r=0.333,P=0.005),与气腹存留时限呈正相关(r=0.296,P=0.014).结论 LC术毕尽量将腹腔内CO2气体排净可缩短术后残气吸收时间.不同压力CO2气腹对LC术后残余的CO2气体量及气腹存留时限无明显影响.LC后肩部疼痛程度随气腹压增高有明显加重趋势,人工气腹引起膈肌的张力可能是造成肩部疼痛的重要原因.     

Portsite and intraabdominal metastases of unsuspected gallbladder carcinoma after laparoscopic cholecystectomy: Report of a case

We herein report a rare case of portsite metastasis of gallbladder carcinoma which occurred after laparoscopic cholecystectomy. A 64-year-old man underwent laparoscopic cholecystectomy at another hospital for symptomatic cholecystolithiasis. The histological examination revealed an adenocarcinoma of the gallbladder infiltrating the entire wall. Despite the physician's advice the patient refused any additional treatment. Thirteen months after surgery he visited our hospital because of a palpable mass at the scar of the right trocar incision. The nodule was removed and histological examination confirmed metastasis from the gallbladder carcinoma.     

Experience with 1904 laparoscopic cholecystectomies at a private hospital

The purpose of this paper is to describe our recent experience in performing laparoscopic cholecystectomies of which we performed 1904, from January 1991 to May 1997, at our private hospital, mainly to treat cholecystolithiasis. The patients included 1563 with gallbladder stones (82.0%), 82 with cholecystocholedocholithiasis (4.3%), 104 with adenomyomatosis (5.5%), 132 with polyps (6.9%), and 23 with gallbladder cancer (1.3%). A difficult pericholecystic dissection led to conversion to open surgery in 61 patients. The average operation time was 63 min. Bile duct injury or cystic artery bleeding occurred in 3 patients with acute cholecystitis, and small intestine injury occurred in 1 patient, while bile leakage or a right subphrenic abscess occurred in 6 patients postoperatively. Although this series included 69 patients with previous upper abdominal surgery, 14 with liver cirrhosis, 267 with a nonvisualized gallbladder, and 148 with acute cholecystitis, the overall conversion rate was only 3.2% and morbidity only 0.5%. Although almost all patients with cholelithiasis are now considered potential candidates for a laparoscopic cholecystectomy, difficulties during cholecystectomy have been encountered in patients with acute cholecystitis. Surgeons should thus be fully prepared to convert to open surgery whenever difficulties are encountered, in order to avoid complication.
