Laparoscopic Gastric Bypass

The stomach is divided into two parts while the smaller part is only around 30ml which is anastomosed to a loop of small bowel that has bypassed the digestive juices for around 75-150cm. Weight loss is achieved by reducing the amount of food intake and bypassing part of the intestine in which nutrients are absorbed. The average weight loss and DM control is superior compared to the sleeve gastrectomy. On the other hand, complication rate including leakage is also higher which can go up to 2%. Patients are also required to take life-long vitamins and mineral supplements after the surgery. The expected weight loss at 2 years is around 70%.

Laparoscopic Sleeve Gastrectomy

The principle of this surgery is to fashion the stomach into a tube-like structure in which the stomach is reduced to around 25% of its original size. Weight loss is achieved by decreasing the amount of food intake and satiety. The excess weight loss at 2 years would be around 60 percent. Patients who undergo the laparoscopic sleeve gastrectomy does not require long term mineral and vitamin supplements and the operative risk is lower than the laparoscopic gastric bypass or duodenal switch. The main disadvantage of the operation is its irreversibility with a leakage rate of around 1%.

冬季喝熱飲 保暖要小心！有機會增加患食道癌風險

世界衞生組織(WHO)轄下已將逾攝氏65度熱飲列入為2A級致癌物，有外科醫生和《東呼即應》分享，指高溫食物會反覆灼傷口腔及食道及破壞內在細胞，長期服用會增加患上食道癌的風險，而且病徵難以察覺，需至中後期才較易發現。醫生警告，本港每年約有300宗至400宗食道癌的新症，其死亡率可超過50%，港人必須要小心！

外科專科醫生陳敬安表示，其實攝氏60度至65度或以上的高溫食物及飲品，均會對身體造成很大影響。其中食道結構內包括口腔、舌頭及喉嚨等均是鱗狀細胞，其抵熱能力約在攝氏60度，一旦超出，細胞中的蛋白有機會壞死，如平時習慣食用或飲用熱食、熱飲速度過快，亦會對人體造成慢性傷害。根據統計及病因研究，吃高溫食物亦是患癌因素之一，尤其是食道癌與慢性熱力的傷害有關。

就食道癌的病徵，陳敬安指，其症狀一般要在中至後期才較為明顯，如食道初段10厘米會出現喉嚨痛，吞嚥開始覺得困難不順，若涉及附近器官或造成聲音沙啞或咳嗽；至於食管中段及底部的症狀，會出現吞咽時感到「哽頸」，即感覺有東西頂着，需要飲水或敲擊胸口才能幫助吞咽的情況，繼而會出現營養不良及開始消瘦；若食道癌發病於食道底部，病人往往先有胃酸症狀，或像胃酸倒流般會感到灼熱及有吞咽阻礙感。

陳又提醒，除了高溫攝氏60度以上的飲料外，其實很辣、具刺激性或醃製的食物均會傷害食管的鱗狀細胞，而油炸及燒烤食物即使放涼後，食物中致癌物質亦有機會仍然存在。

熱飲或會致癌，為何中藥又要趁熱飲？身兼臨床腫瘤科專科醫生及註冊中醫師的蘇子謙解釋，一般建議病人服中藥盡可能溫熱，如是用濃縮中藥藥粉，熱會較易溶解，亦不希望藥力揮發掉才服用，否則會減輕其藥效。但他提醒並非每種中藥都如此，例如清熱解毒的藥放涼服用也沒大分別，街邊涼茶一般都偏向清熱、滋陰及生津，藥性較不會怕放涼而揮發。

那生冷食物、凍飲是否就對身體無害？蘇提醒，腸胃為後天之本，腸胃氣虛的人如長期吃生冷食物，會容易肚痛及消化不良，即使經常吃生冷食物的日本人，當地胃病患者的發病率也頗高；而西方人可能常大魚大肉，食物本身已經帶熱性，喝冷飲則相對減低傷害。他建議大家進食前先留意自己當日用餐狀況，如已吃了一餐熱食的正餐後再喝冷飲，便對人體沒那麼大傷害。

Intragastric Balloon

Intragastric balloons are space-occupying devices which replace gastric luminal volume and may distend the stomach, potentially inducing neurohormonal effects and changes in motility. Application of intragastric balloon therapy should be performed in the context of weight reduction program that extends beyond balloon explantation.

The balloon is removed after one year, weight loss should be maintained to the extent possible using the dietary habits, lifestyle changes, and behavioral modification instilled while the balloon is in place. Literature reviews have shown up to 20% excess weight loss at balloon removal in around 80% patients.

Endoscopic Ultrasound (EUS)

ome tumors of the gastrointestinal tract may be ill-characterized even by Computer Tomography (CT) or Magnetic Resonance Imaging (MRI) due to their anatomical location and behavior. These include submucosal tumors namely leiomyomas and gastrointestinal stromal tumours (GIST). EUS plays an important role in the management of these tumors as it allows for dynamic assessment of size, characteristics, vascularity, as well as providing a means of obtaining tissue samples for histological assessment. The current international guideline recommends EUS as the preferred method for obtaining tissue cytology from GIST of the upper GI tract (oesophagus, stomach & duodenum).

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.

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。
