(Piles)
There is no doubt that hemorrhoids are present in each of us to serve functions such as flatus continence. However, they become problematic when symptoms namely bleeding, constipation, pain and altered bowel habit occur. Due to the high incidence of symptomatic hemorrhoids in places where sedentary lifestyle prevails (i.e. Hong Kong), surgical consultation is mandatory to provide a thorough risk assessment, education, and all surgical options and their prognosis explained to the patient. Since patients with symptomatic hemorrhoids may also present in similar ages of colorectal cancer, colonoscopy may be required for work up in some of these patients to exclude symptoms of hemorrhoids masking the diagnosis of colorectal polyp or cancer. Stapled hemorrhoidopexy can now be offered to avoid external wounds as seen in patients receiving hemorrhoidectomy.

Head and Neck

Salivary gland diseases and cervical lymph node enlargement are among the most common complaints in the head and neck region. While acute infection can cause enlargement of the salivary glands, other pathologies such as tumors may follow a more indolent course. These tumors can present late and only become obvious when they cause disfigurement. Painful enlarged glands require immediate surgical consultation, while painless enlarged glands also warrant thorough investigations to exclude tumors. Cervical lymph nodes are often enlarged subsequent to head and neck infection, however, when no obvious source of infection is identified, they require work up, which sometimes includes surgical resection to exclude malignancy.

Hernia
Abdominal wall hernias are among the most common of all surgical problems with inguinal hernia being the most frequent. Males account for 90% of all inguinal hernia repairs. Conventional “open” repair can be performed under local or general anaesthesia and requires a 2-inch scar in the groin. Minimally invasive options become available in the past years and has been providing patients with an alternative to conventional “open” repair. Endoscopic repairs now only require 3 keyhole scars and are able to tackle both sides’ hernias during the same surgery and has been proven to hasten recovery by causing less pain, while maintains similar surgical success rate.2 Dr. Canon Chan is an experienced surgeon with special interest in hernia surgery and masters the technique of laparoscopic Totally Extraperitoneal (TEP) repair. He has been an active researcher and published his studies on groin hernias.

Disease of the gland is common in adults and the prevalence of thyroid nodules in Asian Chinese is about 46% and it increases significantly with increasing age.1 It is therefore not surprising to find a nodule or two during body checkup or investigation for other conditions. Management of thyroid nodules generally requires “triple” assessment including a detail history and physical examination, thyroid function test, and thyroid ultrasound scan. Thyroid surgery indications are broad and should be individualized for each patient. As there are various treatment options for surgically indicated thyroid lesions, surgical consultation is an essential part of the management of thyroid nodules.

Anti-Reflux Surgery for Gastroesophageal Reflux Disease ( )

GERD is defined as a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Symptoms were considered troublesome if they cause adverse effect on individual’s wellbeing. Complications included esophagitis, malignancy and airway diseases.

GERD is classified into three types: non-erosive reflux disease (NERD), erosive esophagitis (EE), and Barrett’s esophagus. While some authors believe the above entities of GERD are independent rather than a progression from one end of the spectrum to the other, most study on natural history of NERD support the progression of GERD to EE in patients without treatment.

Minimally invasive or laparoscopic anti-reflux surgery (LARS) now offers patients with a surgical cure to their troublesome GERD symptoms. LARS has been proven by evidence to be a safe and cost-effective alternative to long term PPI. Patients received LARS generally enjoys improved quality of life.

中三生誤以為痔瘡，竟確診第3期腸癌！6大症狀務必留意

便血恐是腸癌警訊！
大陸杭州一名中三學生小天（化名）發現自己大便出血，家人起初以為只是久坐導致痔瘡，並未立即送醫。然而，隨著便血情況日益嚴重且頻繁，家人才帶他就醫，沒想到檢查結果顯示，他已罹患 第3期結直腸癌。最終，小天不得不接受手術切除腫瘤，並在化療期間兼顧學業與考試。

年輕人腸癌風險上升，飲食與生活習慣成關鍵
現代年輕人生活作息不規律，飲食習慣不佳，例如 高脂高紅肉飲食、缺乏膳食纖維、愛吃宵夜、少運動，這些因素都與腸癌發病息息相關。特別是 有家族病史或壓力過大者，更應提高警覺，建議35歲以上人士定期接受胃腸鏡檢查，以便及早發現病變。

腸癌6大警示症狀
1. 大便異常：糞便帶血、呈黑色、帶黏液，或直腸出血
2. 排便習慣改變：長期便秘或腹瀉，糞便變細條狀
3. 體重無故下降
4. 腹部不適：腹脹、腸絞痛
5. 排便未盡感：如有糞便仍殘留的感覺
6. 貧血徵兆：手腳冰冷、疲倦、心跳加快、氣喘、面色蒼白、頭暈

如出現上述症狀，務必盡早就醫，切勿忽視！

#唾液腺疾病 和 #頸淋巴結腫，是頭頸部位最常見的疾病。而病毒性腮腺炎是腮腺最常見的發炎性疾病，主要症狀為急性發作的單側或雙側腮腺紅腫脹痛。由於屬突急性感染，可能導致唾液腺擴大，但即使出現病變如腫瘤，病徵卻不明顯。因此，這些腫瘤病徵往往晚期才會出現，而且只有在造成損傷時，才會變得明顯。

擴大的腺體如出現疼痛，有可能需要立即進行手術切除，即使腺體無任何痛楚，亦應作徹底檢查以排除腫瘤的可能性。

而頸部淋巴結經常在頭頸部感染後擴大，若脖子腫脹處，按壓起來疑似有硬塊，勿掉以輕心，即使沒有明顯的感染源被識別時，亦需要進行徹底檢查及治療，包括手術切除，以排除惡性腫瘤。

有吞嚥困難？
針對賁門失弛緩症的內窺鏡肌切開術（POEM）

吞嚥困難是鑑別診斷 #賁門失弛緩症 患者的一種特徵。普遍視為是一種退化性疾病，下食道肌肉在正常吞嚥期間不能放鬆，並導致食物「滯留」 。

由於症狀相似，賁門失弛緩症可能被誤認為是更常見的疾病，如胃食管反流病（GERD）、裂孔疝，甚至心身疾病。
=====
POEM（Peroral Endoscopic Myotomy）由H·Inoue教授於2008年引入。這項最先進而有效的手術正逐漸地成為治療賁門失弛緩症的新標準。該手術包括在食管中部製造粘膜下隧道，隨後通過食管壁的圓形肌肉的肌切開術。肌切開術的長度通常比手術切開術長，然而在手術中，常規切開術是全厚度的。所有吞嚥困難的患者，83％至94％有非心胸痛。儘管大多數患者不需要藥物治療，但有約46％的患者於術後有輕度胃食管反流。

大腸癌 病徵與不少都市病相似或毫無表徵

大腸癌常見病徵包括突然消瘦和沒有胃口等，最明顯是大便習慣轉變，例如大便呈黑色丶帶血丶腹瀉或便秘持續數星期至數個月不等，服腸胃藥亦不奏效。

不少都市病例如痔瘡丶腸炎丶胃潰瘍等有類似徵狀，或令腸癌患者延遲求醫，約一成大腸癌個案發現於晚期。

此外，約四成大腸癌發生於右邊的升結腸位置，患者大便未必帶血，反而出現貧血徵狀，亦可能毫無表徵。

👉故此，五十歲或以上人士，除了每隔一至兩年應接受大便隱血檢測，亦應考慮每十年檢查一次全結腸鏡。👈

陳敬安建議，平日多進食高纖食物丶多吃水果丶芝士和牛奶等奶類製品，有助促進腸胃活動，減低患大腸癌風險。每周進食超過五份紅肉丶酗酒丶吸煙丶肥胖都是患大腸癌的風險因素，宜盡量避免。

大腸癌高危因素：
1.患潰瘍性結腸炎等腸道慢性疾病
2.有家族病史
3.肥胖
4.吸煙
5.酗酒
6.每星期進食超過五份紅肉
7.男性
8.年齡50歲或以上
