Skin and Scar

Skin and subcutaneous lesions such as sebaceous cyst, lipoma, warts and scar complications are commonly referred to surgeons. Some of these can be managed by office surgery under local anesthesia. More complex lesions such as skin cancers sometimes require thorough planning and histological examination before surgery. Surgical treatment for most of these lesions is in general very safe and patients usually discharge home on the same day of surgery.

Ambulatory pH Analysis and Manometry
Gastroesophageal reflux disease (GERD) is among the most common disorder in modern medicine. While the most effective acid suppression medications are the proton pump inhibitors (PPI), a mere 60% of treated patients will show improvement of their symptoms. Among the “non-responders” to PPI, some may benefit from surgical correction of their acid reflux and achieve cure of their troublesome symptoms. As the immergence of minimally invasive anti-reflux surgery with low magnitude of risk comparable to cholecystectomy, many patients can now benefit from surgical treatment and avoid the long term side effects of PPIs. For patients considering surgery as a long term alternative to PPI it is imperative that their acid reflux disease be objectively assessed, such that a physiological & functional profiling is possible for each patient. This GERD patient profile is important during the discussion on the severity of GERD and the prognosis subsequent to surgical correction.

Abrupt onset agonizing abdominal pain

Appendicitis, pancreatitis, cholecystitis, diverticulitis and perforation of the gastrointestinal tract are common abdominal pathologies that require immediate surgical attention. These surgical problems usually share the complaint of abrupt onset agonizing abdominal pain and usually not amenable to regular painkillers. Immediate surgical consultation is necessary to rectify these conditions as delay presentation can lead to the development of complications and worse mortality.

are common among Asian Chinese, although most are asymptomatic, patients whom have been investigated for epigastric pain with a negative upper endoscopy should undergo an ultrasound scan of the upper abdomen to exclude the presence of gallstones.

A typical patient at risk of acquiring gallstones will be an obese lady above 40 and enjoys high fat and low fiber diet. Other risk factors include pregnancy, family history of gallstones, diabetes, and chronic use of medications that contain estrogen, such as oral contraceptives or hormone therapy drugs. While quiescence gallstones do not demand urgent attention, gallstones that causes pain, indigestion, infection and complication such as peritonitis requires prompt surgical consultation to consider removal of the diseased gallbladder.

Current gold standard approach to removal of the diseased gallbladder is by laparoscopic surgery, which requires only 3 to 4 small keyholes on the abdomen as compared with the big scar in conventional “open” surgery. An elective laparoscopic removal of gallbladder typically requires only 1-2 days of hospitalization and patients can enjoy early resumption to normal duties due to early recovery made possible by minimally invasive surgery.

誰適合或需要進行肝臟檢查?
• 患有乙或丙型肝炎人士,應定期檢查
• 家族有乙型肝炎及肝癌病史
• 酗酒人士
• 40歲或以上、患有糖尿病、體重指標(BMI)達30的人士

若是早期的肝癌,肝功能尚算良好,便可接受手術切除腫瘤。如肝癌手術後仍未能清除癌細胞,便有需要接受射頻消融術、經導管肝動脈化療栓塞治療、放射治療、注射酒精等方法。若果以上方法都無效,便可選擇標靶治療或配合其他治療使用或接受肝臟移殖。

肝功能測試(Liver function test, LFT)有助診斷肝病,透過抽血檢查血液內的鹼性磷酸酶(ALP)、甲胎蛋白(AFT),確認病情。透過驗血,可反映肝炎、病毒和肝癌情況,超聲波則能找出肝癌細胞,肝纖維化掃描 (Fibroscan) 評估發炎及肝硬化程度。

FibroScan發出衝擊波穿過皮膚進入肝臟,再利用超聲波來量度衝擊波的速度,從而測量肝臟的軟硬度。如肝臟硬度越高,則代表肝纖維化問題越嚴重。

肝纖維化掃描檢查適合檢驗下列慢性肝病所引起之肝纖維化:
• 慢性乙型肝炎
• 慢性丙型肝炎
• 非酒精性脂肪肝

由於肝臟的更新能力強,即使肝功能只有三至四成仍能正常運作。所以肝癌早期沒有症狀。肝癌後期的症狀包括上腹漲痛、腹部漲大積水、黃膽、貧血及容易感到疲倦等。四分一乙型慢性肝炎病人,演變成肝硬化或肝癌。不希望自己的肝臟走到那一步,慢性肝病患者應定...

由於肝臟的更新能力強,即使肝功能只有三至四成仍能正常運作。所以肝癌早期沒有症狀。肝癌後期的症狀包括上腹漲痛、腹部漲大積水、黃膽、貧血及容易感到疲倦等。
四分一乙型慢性肝炎病人,演變成肝硬化或肝癌。不希望自己的肝臟走到那一步,慢性肝病患者應定期監測肝纖維化的演變。無創肝纖維化掃描器,為患者提供一個簡單而安全的方法來檢查肝纖維化的情況。

什麼是肝纖維化?
當細胞不斷發炎,肝臟在重複發炎和再生過程中,就像在傷口上不停抓癢,最終留下如疤痕般的纖維化組織,也是大家熟悉的肝纖維化。沒有得到適當治理會使肝臟纖維化肝越嚴重,並增加患肝癌的風險。

什麼是脂肪肝?
脂肪肝是指肝臟細胞內過多的脂質積聚,導致整個肝臟的脂肪量超過正常水平。一般脂肪性肝炎的患者可能沒有明顯的病徵,但發炎情況持續存在。當出現肝纖維化或肝功能受損時,或者在定期身體檢查時,才無意中被發現。因此,建議應定期作身體檢查,有助及早發現並治療。

Breast cancer is the number one cancer in incidence among Hong Kong females and ranks third in cancer mortality. The incidence of female breast cancer rises abruptly after the age of 25 and peaks at 65. While some breast cancers are screen-detected, others possess symptoms of breast pain, lumps, skin changes or discharge around the ni***es. Risk factors for breast cancer have been identified and patients harboring them and experiencing breast symptoms should seek prompt surgical consultation. These risk factors are:

1. Being female
2.Increasing age
3.A personal history of breast cancer
4. A family history of breast cancer
5. Inherited genes that increase cancer risk
6. Radiation exposure
7. Obesity
8. Prolong female hormone (estrogen) exposure
9. Alcohol

Upper endoscopy has been an important investigation for many upper GI complaints including epigastric pain, vomiting, indigestion, acid reflux, weight loss and unexplained anaemia. However, certain “red flags” demands a prompt attention and patients should seek referral for an early upper endoscopy.

These “red flags” include:
.patients over 40 year old with dysphagia, weight loss, anaemia, passage of black loose stool
.family history of gastric or esophageal cancer
.chronic non-steroidal anti-inflammatory drug use
.suffering from GERD symptoms for more than 5 years
