ANVH EP- 104 Esophagus feeding-tube

Understanding the Esophagostomy Tube (E-Tube)
When a dog or cat stops eating due to severe illness, pancreatitis, kidney disease, or feline hepatic lipidosis, adequate nutrition is critical for recovery.

An Esophagostomy tube (E-tube) is a soft silicone feeding tube placed through a tiny opening on the left side of the neck directly into the esophagus. Because it bypasses the mouth and nose, your pet can still drink and eat canned food or treats voluntarily. Most importantly, it eliminates the stress of force-feeding, providing a calm, reliable way to deliver food, hydration, and oral medications.

When Can the Tube Be Removed?
The E-tube is a temporary nutritional bridge. Once your pet has recovered enough to voluntarily eat 75%–85% of their daily caloric requirement for several consecutive days while maintaining stable body weight, the tube can be removed.

Tube removal takes just seconds and requires no general anesthesia. The small stoma in the neck begins to seal quickly and heals on its own within a few days to a week.

===========================================
認識「食道胃管（E-tube）」，生病毛孩的營養生命線

當毛孩因為嚴重疾病、手術、胰臟炎、腎臟病，或是貓咪因食慾廢絕引發脂肪肝危機時，「營養」往往是戰勝疾病最關鍵的基礎。很多時候，毛孩不是被疾病擊垮，而是因長期熱量不足、器官耗損而衰竭。此時，獸醫師常會建議放置「食道胃管（Esophagostomy tube，簡稱 E-tube）」。許多家長一聽到「插管」，往往感到焦慮與心疼，但事實上，食道胃管是一項創傷小、舒適度極高，且能救命的溫柔工具。

一、 什麼是食道胃管（E-tube）？
食道胃管是一根柔軟的醫療級矽膠管，醫師會在極短時間的輕度麻醉下，從毛孩的左側頸部皮膚開一個微小孔洞，將管子順入食道、末端延伸至胸段食道近胃處。

不影響正常進食與喝水：管子繞過了口腔與咽喉，毛孩想自主吃肉泥、喝水完全不會受到干擾。

無鼻咽刺激感：比起細小的鼻胃管（容易引發打噴嚏、流鼻水且需戴巨大頭套），食道胃管毛孩的耐受度高出許多。

管徑較寬、用途廣泛：可灌食糊狀罐頭、重症處方泥，並能直接透過管子投藥與補水，徹底告別「跟毛孩搏鬥強迫灌食」的痛苦與壓力。

二、 居家灌食標準操作流程（「回抽、慢灌、沖洗」三字訣）
在家中使用食道胃管並不困難，只要掌握規律與細心即可：

步驟 1：準備與加溫食物
將醫師指定的處方罐頭加水（或專用營養液），使用果汁機或攪拌棒打成細緻均勻的奶昔狀／泥狀，避免未打碎的肉渣堵塞管腔。

溫度控制：食物需回溫至微溫（約 37°C–38°C，接近體溫）。切忌冰冷灌食，以免誘發胃痙攣或劇烈嘔吐。

步驟 2：進食前「回抽確認（Check Residual）」
用空針筒連接餵食管接頭，輕輕往回抽吸。

如果抽出大量未消化的食物或胃液：表示上一餐尚未完全排空，請暫停本次灌食，並聯繫獸醫師。

抽吸正常（微量或無阻力）：注入 3–5 mL 溫開水潤滑管壁，即可開始餵食。

步驟 3：緩慢灌食（慢就是快）
速度是防嘔吐的關鍵：每 10–20 mL 的食物建議推注 1–2 分鐘以上，一餐完整的熱量通常需在 15 至 20 分鐘 內緩慢且溫和地給予。

過程中若毛孩出現頻繁舔舌、吞口水、焦躁不安、乾嘔，表示推注速度過快或胃部壓力過高，請立刻暫停，休息 5–10 分鐘後再減速給予。

步驟 4：餐後溫水沖洗（Flush）
灌食結束後，務必使用 5–10 mL 的乾淨溫開水 徹底沖洗管壁，確保沒有殘留肉泥黏附在管內發酵或堵塞。

蓋緊管口防塵塞，收妥固定。

三、 頸部傷口護理與包紮注意事項
食道胃管一般需要留置數週，傷口的日常維護是預防感染的核心：

每日檢查傷口一次：

輕輕掀開外層繃帶或專用頸套，觀察穿出造口處皮膚。

正常傷口周圍可能會有少量乾燥淡黃色分泌物；若出現紅腫熱痛、膿性分泌物或惡臭，需立即向醫師反映。

清潔與更換敷料：
使用無菌生理食鹽水棉棒，由傷口中心向外以旋轉方式輕柔擦拭乾淨。
依醫囑覆蓋無菌紗布（通常為 Y 型紗布），並使用透氣包紮帶或專用魔鬼氈防抓護頸領圈固定。

防止毛孩抓撓：
術後務必配戴伊莉莎白頸圈（E-collar），或確保專用頸套包覆完好，避免毛孩用後腳抓勾將管子扯脫。

四、 出現以下狀況，請立即聯繫動物醫院！
管子意外滑脫或被扯出：
緊急處置：切勿自行將管子推回體內！ 請立刻用乾淨紗布輕壓住頸部傷口，並在最短時間內帶毛孩回院處理。

管腔嚴重堵塞：
若推注溫水阻力極大，切勿用力硬推。可先嘗試用溫水回抽浸潤 10–15 分鐘；若仍無法暢通，請交由專業醫護處理。
持續性嘔吐、腹瀉，或發燒、精神極度萎靡。頸部傷口周圍明顯腫脹，或毛孩在推注食物時出現劇烈咳嗽、呼吸急促。

何時可以拔管？
食道胃管是一座「營養過渡的橋樑」。當毛孩的原本疾病逐漸受控，並能主動自行進食達到每日所需熱量的 75%–85% 以上且持續數天，體重維持穩定時，獸醫師就會評估為毛孩拆除管子。

拔管過程極為簡單迅速，通常不需要二次全身麻醉；拔除後造口處會在一週內迅速自行收斂閉合。

ANVH EP- 103 Femur fracture in small breed dogs

Today, A Niu would like to introduce a case of femur fracture

The femur (thigh bone) is the main weight-bearing bone in your dog’s back leg. When it breaks, strong surrounding thigh muscles pull the bone fragments completely out of alignment.

1. Why Surgery is Necessary (No Casts)
Because the femur sits high up inside thick muscle, a cast or splint cannot hold it in place. Without surgery, the loose ends will constantly grind, causing extreme pain, internal damage, and permanent lameness. Surgery is required to pull the bone ends back together and lock them in position.

2. How the Surgery Works
Realignment: Under full anesthesia, the surgeon accesses the bone through an outer-thigh incision and fits the broken ends back together like puzzle pieces.

Rigid Internal Fixation: The bone is stabilized using:

Bone Plates & Screws: High-grade titanium or stainless steel plates are contoured to the bone and screwed in place to hold it rock-steady.

Intramedullary (IM) Pin: A steel rod placed down the center of the bone, often paired with a plate or orthopedic wire for extra support.

Post-Op X-rays: Taken immediately to confirm ideal alignment and implant placement.

3. The Role of the Implants
Temporary "Scaffolding": The metal plate bears the weight only while the bone produces new bone cells to knit itself back together.

Do they stay in? Yes. Surgical-grade implants are biocompatible and stay inside permanently unless rare complications (like infection or loosening) occur.

4. Expected Outcome
Locking the bone ends stops painful friction right away, providing rapid relief within days. With strict rest during the healing phase, most dogs make a full recovery and return to normal running and playing in 8 to 12 weeks.

If ur dog has a similar problem, please contact ur family vet ASAP.
===========================================
今天阿牛要介紹一個小型犬,股骨斷裂手術修復的case

股骨是大腿最主要的承重骨。當股骨斷裂時，周圍強壯發達的大腿肌肉會強烈收縮，把斷裂的骨頭往兩側拉扯，造成明顯錯位與重疊。

1. 為什麼必須手術？（不能只打石膏）
大腿骨位置太高且包覆在厚實肌肉內，外層的石膏或夾板完全無法固定它。如果不動手術，斷骨會在體內持續摩擦，造成劇痛、肌肉內出血與永久跛行。唯有透過手術，才能將錯位的骨頭拉回原位並徹底固定。

2. 手術是如何進行的？
骨折復位：在全身麻醉與嚴格無菌下，外科醫師在大腿外側劃開切口，避開神經血管，將錯位的骨頭像拼圖一樣對齊拼回。

堅強內固定：使用醫療級金屬植入物鎖住斷骨，常見方式包括：
骨板與骨釘：沿著骨骼弧度貼上鈦合金或不鏽鋼骨板，並鎖入多顆骨釘，牢牢吸收走動時的受力。
骨髓內釘：在骨頭中空的髓腔內穿入鋼釘作為軸心支撐，常搭配骨板或鋼線加強穩定。
術後 X 光檢查：縫合完成後立即拍攝 X 光，確認骨頭對齊與植入物位置完美到位。

3. 鋼板與骨釘的角色
暫時的「結構鷹架」：鋼板的作用是「暫時代替骨頭受力」，提供一個絕對穩定的環境，讓骨頭自己長出新骨細胞（骨痂）重新接合。

以後需要拆除嗎？：不需要。醫療級植入物生物相容性極高，會終身留在體內，除非極少數感染或螺釘鬆脫等特殊狀況才需取出。

4. 預後與復原期
一旦斷骨被鋼板鎖緊不再相互摩擦，狗狗在術後幾天內疼痛就會大幅減輕。只要術後嚴格配合限制活動，絕大多數毛孩都能在 8 至 12 週內完全康復，重新恢復正常跑跳與玩耍。

如果你的狗狗有類似的症狀,請趕快跟你的家庭獸醫聯絡

🐱 [Pet Health] Frequent Vomiting & Weight Loss in Cats? Watch Out for GI Tumors!

Does your cat vomit often or lose weight mysteriously? Don't dismiss it as just hairballs or a sensitive stomach. Gastrointestinal (GI) tumors—especially Lymphoma— are among the most common cancers in cats.

🚨 4 Warning Signs to Watch For:
1️⃣ Frequent Vomiting: Vomiting more than twice a month.
2️⃣ Weight Loss: Unexplained weight loss or loss of muscle mass.
3️⃣ Appetite Changes: Picky eating or progressive loss of appetite.
4️⃣ Bowel Issues: Chronic diarrhea, soft stools, or dark/tarry stools.

🩺 Diagnosis & Treatment:
Diagnosis involves an abdominal ultrasound to check intestinal wall layers, alongside FNA or biopsy to confirm the exact tumor type.
Many low-grade lymphomas respond very well to oral chemotherapy, while solitary tumors can often be managed with surgical resection!

💡 Vet Tip:
Vomiting is NEVER "normal" for cats. Early diagnosis is key to protecting your feline friend's quality of life! ❤️



Please contact ur family cat ASAP if ur pet has a similar issue.

之前的子宮蓄膿+乳腺瘤原來已經發過了,今天重發-貓咪的胃腸道腫瘤

🐱 【毛孩健康】貓咪頻繁嘔吐、越來越瘦？小心「胃腸道腫瘤」！

你家貓咪常吐毛球？吃得少卻一直變瘦？別以為這只是單純腸胃敏感！在貓咪常見的惡性腫瘤中，胃腸道腫瘤（尤其是淋巴瘤 Lymphoma） 是相當常見的隱形殺手。

🚨 出現以下 4 大警訊請提高警覺：
1️⃣ 頻繁嘔吐： 一個月嘔吐超過 2 次（含食物、胃液或膽汁）。
2️⃣ 體重下滑： 不明原因體重減輕、背脊變明顯。
3️⃣ 食慾改變： 食慾忽好忽壞或漸進式厭食。
4️⃣ 排便異常： 長期下痢、軟便或黑便。

🩺 如何檢查與治療？
透過 腹部超音波 評估腸壁結構，並搭配 細針抽吸（FNA）或切片檢查 確診腫瘤類型。
多數低階淋巴瘤對 口服化療藥物 反應良好；孤立性腫塊也可透過 手術切除 結合後續治療，有效提升生活品質！

💡 獸醫師提醒：
嘔吐絕對不是貓咪的日常！早期診斷、早期介入，才能給毛孩最好的照顧❤️

#貓咪衛教 #貓胃腸道腫瘤 #貓淋巴瘤 #貓咪嘔吐 #毛孩健康 #獸醫日常

這個case是典型的T-cell lymphoma,預後很糟糕,手術切除腫瘤並進行腸吻合後動物暫時的恢復食慾跟精神,但可預期的這會很快的又再長回來

ANVH EP- 101 C-section in cats 貓的剖腹產

Patient: 3–4 year old female cat.

Chief Complaint: No prior prenatal checks; owner knew she was pregnant and in labor, but she experienced prolonged dystocia (unable to deliver).

Diagnosis: Examination revealed two fetuses—one was still viable, while the other had no detectable heartbeat. Emergency C-section was advised and agreed upon.

Surgery: Emergency C-section was performed smoothly, taking about 10–15 minutes.

Fetal Status: Both kittens showed no signs of breathing or heartbeat (stillborn state) upon extraction.
Resuscitation: The medical team performed continuous CPR for over 20 minutes, successfully bringing one kitten back to life.

Served as a critical learning experience for new team members and interns, allowing them to witness a feline C-section and observe Day 0 newborn status firsthand.

20 minutes of relentless effort to pull a newborn back to life. 🐾

We recently handled an urgent feline C-section case. A 3-to-4-year-old mom-to-be came in with dystocia. She had no prior prenatal exams, and despite showing clear signs of labor, she just couldn't deliver. A quick diagnostic scan showed two kittens—one was still holding on, but the other had already lost its heartbeat.

To save mom and the remaining baby, we immediately rushed into an emergency C-section.

The surgery itself was quick and smooth, taking only about 10 to 15 minutes. However, the moment we brought the two little ones out, our hearts sank—neither kitten had a pulse or breathing.

"Don't give up. Keep resuscitating!"

Our team kept going with continuous CPR. After more than 20 intense minutes, a faint, miraculous gasp finally came through. We managed to pull one of the kittens back from the brink. ❤️

For our clinic, every saved life is a win, but this case was extra special. It gave our new team members and interns their very first look at a live C-section and what a Day 0 newborn truly looks like in the ER.

Nature is tough, but a team that refuses to give up is tougher.

3–4 歲未絕育母貓。

主訴：飼主先前未做過產檢，僅知懷孕且已達預產期。貓咪出現分娩動作但持續難產。

診斷：經進一步產檢發現胎兒共兩隻，其中一隻生命征象尚可，另一隻已無心跳。與飼主討論後決定進行緊急剖腹產。

手術過程：剖腹產過程順利，耗時約 10 至 15 分鐘。
胎兒狀況：兩隻胎兒取出時均呈無呼吸心跳（死胎）狀態。
醫療團隊持續進行心肺復甦超過 20 分鐘，最終成功救回其中一隻幼貓。

這個case提供了團隊新進成員與實習生寶貴的臨床經驗，首次實地觀察犬貓剖腹產流程及 Day 0 剛出生胎兒的生理狀態。

【20 分鐘的堅持，搶救剛誕生的新生命 🐾】

這天接到一個緊急的剖腹產病例。

一隻 3 到 4 歲的媽媽，因為先前沒有做過相關產檢，到了預產期雖然出現生產行為，卻一直無法順利產下寶寶。來院經過緊急檢查後發現，肚子裡的兩隻小貓，其中一隻已經失去了心跳。

為了保住媽媽與剩下的寶寶，我們迅速安排了緊急剖腹產。

雖然手術過程非常順利，大約 10 到 15 分鐘就完成，但當兩個小傢伙從子宮出來的那一刻，大家的心都沉了下來——兩隻寶寶當時都沒有呼吸與心跳。

「不要放棄，繼續復甦！」

醫療團隊沒有停下手中的動作，持續進行心肺復甦。經過超過 20 分鐘不間斷的努力，我們終於聽到了那聲微弱卻無比動人的呼吸聲，成功搶救回其中一隻小生命！

先前的剖腹產案例細節大家可以往前翻閱舊文。對我們團隊來說，這個案例除了救回珍貴的生命，也是非常寶貴的臨床教學機會。讓剛加入的新人與實習生們，第一次親眼見證犬貓剖腹產的完整過程，以及 Day 0 剛出生胎兒最真實的模樣。

生命真的很韌性，也謝謝團隊每一個不放棄的瞬間 ❤️

貼心提醒：定期產檢能大大降低難產與胎兒風險，準媽媽們記得按時檢查喔！

ANVH EP- 100 GI foreign body in cats

A Niu would like to introduce a case of GI foreign body in cats

GI foreign bodies in cats are true emergencies, especially because cats are uniquely prone to linear foreign bodies (string, thread, yarn) that can rapidly cause intestinal plication and perforation.

What Cats Commonly Swallow - String, yarn, thread, ribbon, tinsel, Hair ties, dental floss, Plastic pieces, toys, socks, jewelry

Cats are at particularly high risk for linear foreign bodies, which can anchor under the tongue or in the stomach and cause the intestines to “accordion” and tear.

🚨 Clinical signs include:
Persistent or intermittent vomiting
Anorexia or decreased appetite
Lethargy, hiding, restlessness
Drooling, gagging, or regurgitation
Abdominal pain or discomfort
Visible string from the mouth or a**s
Even early signs may be subtle, so any suspicion warrants same‑day evaluation.

🧪 Diagnosis
Physical exam, including mandatory check under the tongue for anchored string
Abdominal radiographs: segmental intestinal dilation; small intestine >1.2 cm raises suspicion
Exploratory surgery if obstruction is unclear or severe

🛠 Treatment
Endoscopic removal: ideal for stomach foreign bodies or,
Surgery (gastrotomy/enterotomy): required for most obstructions, especially linear FBs
Multiple enterotomies often needed for string cases
Bowel resection if perforation or necrosis

Supportive care: IV fluids, analgesia, anti‑nausea meds, antibiotics if peritonitis

📈 Prognosis
Excellent with early removal
Guarded if perforation, sepsis, or extensive resection
Hospitalization typically 1–3 days for simple cases; 5–7+ days for complicated ones

❌ What Owners Should Not Do
Do not pull visible string
Do not induce vomiting
Do not wait to “see if it passes”
These actions can worsen intestinal tearing.

✔️ Immediate Action
If a cat is vomiting, drooling, painful, or suspected of swallowing string or an object:
Seek veterinary care immediately. Early intervention saves lives.

If you suspect ur cat has similar symptoms, please contact ur family vet ASAP
===========================================
今天阿牛要介紹的是貓咪胃腸道異物的case

胃腸道異物在貓咪是真正的急診!! 醫療要盡早介入!!

貓咪常見吞下的異物種類包括:
線狀物：線、毛線、絲帶、牙線、髮圈
塑膠碎片、玩具、布料、橡皮筋
金屬小物件、飾品
貓特別容易吞食線狀異物，最危險的是造成 腸道摺疊（plication）與穿孔。

🚨 臨床症狀
持續或間歇性 嘔吐/食慾下降、拒食/嗜睡、躲藏/流口水、乾嘔/腹痛、腹部敏感/口腔或肛門可見線頭

🧪 診斷重點
身體檢查：務必檢查 舌下是否有線卡住
X 光：腸段不均一擴張；小腸直徑 >1.2 cm 提高阻塞疑慮
腹部超音波：評估腸道蠕動、異物影像
內視鏡：胃內異物可嘗試取出
探查手術：阻塞明顯或疑似線狀異物時常需進行

🛠 治療方式
內視鏡取出：適用於胃內異物
手術（gastrotomy/enterotomy）：多數腸阻塞需要
多段腸切開：線狀異物常需多處 enterotomy
腸切除：若有壞死或穿孔
支持療法：靜脈輸液、止痛、止吐、抗生素（若有腹膜炎）

📈 預後
早期處理：預後佳

❌ 主人不應做的事
不要拉 任何從口或肛門露出的線
不要催吐
不要等待異物自行排出
這些行為可能導致腸道撕裂!!

如果你的貓有類似的症狀,請盡快跟你的家庭獸醫聯絡

ANVH EP- 99 Pyometra and mammary gland tumor in dogs(Clinical review)

Today, A Niu would like to share a case of pyometra + mammary gland tumor removal(clinical review)
If you have a non-spayed dog that starts drinking a lot, peeing a lot, is lethargic, and you see pus-like discharge coming out from the va**na, then you need to worry about pyometra.

Why Pyometra and Mammary Tumors Often Occur Together
Both diseases are strongly linked to chronic hormonal exposure, especially progesterone, in intact female dogs.

After each estrus, dogs enter diestrus, where progesterone remains elevated for 2–3 months.
Uterus: Progesterone → cystic endometrial hyperplasia (CEH) → bacterial infection → pyometra
Mammary glands: Progesterone → glandular proliferation → increased risk of mammary tumors

Result:
Older intact females have a high likelihood of developing both pyometra and mammary tumors.

Clinical Relationship Between the Two Diseases
High coexistence rate
Studies show:

Over 50% of dogs with mammary tumors also have CEH or uterine abnormalities.
Pyometra is more common in older intact females — the same population at highest risk for mammary tumors.

Estrus cycle influence
Progesterone stimulates mammary tissue → tumor growth
Progesterone also drives uterine changes → CEH → pyometra

Systemic signs: lethargy, PU/PD, vomiting, va**nal discharge → suspect pyometra

Diagnostic Approach When Both Conditions Are Suspected
Essential diagnostics
CBC: leukocytosis, toxic changes
Biochemistry: renal and hepatic parameters
Abdominal ultrasound: enlarged, fluid-filled uterus
Thoracic radiographs: check for metastasis

Key point:
If a dog with mammary tumors shows systemic illness, always rule out pyometra.

Treatment Strategy
⭐ Priority: Treat Pyometra First (Life-threatening)
Emergency ovariohysterectomy (OHE)
Removes infection source and stabilizes the patient
Some mammary masses near the incision may be removed simultaneously

Mammary tumor surgery (second stage)
Performed once the patient is stable
Allows proper staging and surgical planning

Why not treat the mammary tumor first?
Pyometra can rapidly lead to sepsis, renal failure, uterine rupture, death
Mammary tumors are usually chronic, not immediately life-threatening
Anesthetic risk is significantly higher during active pyometra

Mammary tumors
About 50% are malignant
Early removal + OHE reduces recurrence and new tumor formation

OHE is both therapeutic and preventive for both conditions.
===========================================
Pyometra（子宮蓄膿症） 和 Mammary gland tumor（乳腺腫瘤） 在母犬是高度相關的兩大疾病。
臨床上，這兩者常常「一起出現」或「互相影響」，因為它們都與 長期未結紮、反覆受黃體素刺激 有直接關係。

🩺 1. 為什麼 Pyometra 和 Mammary Tumor 常常一起發生？
🔬 共同病因：長期荷爾蒙刺激（Progesterone）
未結紮母犬在每次發情後進入 diestrus，此時：Progesterone 高濃度持續 2–3 個月-->子宮：形成 CEH → Pyometra
乳腺：促進腺體增生 → 乳腺腫瘤風險上升

未結紮母犬年齡越大 → Pyometra + Mammary tumor 的機率越高

🧬 2. 乳腺腫瘤與 Pyometra 的臨床連結
乳腺腫瘤的母犬常常同時有子宮病變
研究顯示：乳腺腫瘤犬中 >50% 有 CEH 或子宮異常
年長未結紮母犬更容易在同一時間出現 乳腺腫瘤 + Pyometra
乳腺腫瘤可能因發情週期惡化: 黃體素刺激乳腺組織 → 腫瘤增長
同時刺激子宮 → CEH → Pyometra

臨床上常見情境
老年未結紮母犬+乳腺腫瘤多年未處理
最近發情後 4–8 週出現 食慾下降、PU/PD、陰門分泌物 → Pyometra

🩻 3. 診斷策略（兩者同時存在時）
必做檢查：
CBC：白血球上升、毒素性變化
Biochem：腎指數、肝指數
Abdominal ultrasound：子宮擴張、液體
Thoracic radiographs：乳腺腫瘤是否轉移
🏥 4. 治療策略（臨床決策重點）
⭐ 若同時有 Pyometra + Mammary tumor → 優先處理 Pyometra（救命）
緊急 OHE（卵巢子宮切除術, 移除感染源同時穩定全身狀況
同時可移除部分乳腺腫瘤（若位置允許）

乳腺腫瘤手術（第二階段）
待病患穩定後再做
若腫瘤小且靠近 OHE 切口，可同時處理

❗ 為什麼不先做乳腺腫瘤？
Pyometra 是 急症，可能敗血症、腎衰竭、子宮破裂
乳腺腫瘤通常是 慢性病，不會立即致命
手術風險在 Pyometra 時更高（麻醉、循環不穩）

📈 5. 預後
Pyometra：
早期手術 → 預後良好
早期切除 + OHE 可降低復發與新腫瘤形成
若已轉移 → 預後差

OHE 是兩者最有效的預防與治療輔助方式

早期發現,早期治療,絕育可以幫主人省下數千塊的醫療費用跟風險

ANVH EP- 98 Third Eyelid Gland Prolapse in Cats 貓的第三眼瞼外翻

The third eyelid (nictitating membrane) contains a tear gland responsible for producing about 30–40% of total tear volume.
When the connective tissue anchoring this gland becomes loose or inflamed, the gland protrudes from the inner corner of the eye as a red, rounded mass.

Cherry eye is less common in cats than in dogs, but it does occur—especially in:
Persian and Exotic Shorthair cats
Cats with chronic conjunctivitis
Cats with eyelid or third eyelid laxity
Rarely, cats with third eyelid tumors or foreign body irritation

📌 Clinical signs
Red, round swelling at the inner corner of the eye
Increased tearing or discharge
Conjunctivitis
Ocular irritation or pawing at the eye
Sometimes accompanied by third eyelid elevation or eyelid inflammation

📌 Why the gland should NOT be removed
The third eyelid gland produces a significant portion of tears.
Removing it can lead to keratoconjunctivitis sicca (KCS), which is harder to manage in cats and may cause:
Chronic corneal inflammation
Corneal ulceration
Vision impairment
Lifelong medication

Therefore, preservation and surgical repositioning of the gland is the standard of care.

📌 Treatment
1. Surgical replacement (gold standard)
Techniques include:
Pocket technique
Anchoring technique
Surgery in cats is more delicate than in dogs due to thinner tissues and a smaller third eyelid, but success rates are high.

2. Medical support
Topical antibiotics
Anti‑inflammatory eye medications (as appropriate)
Elizabethan collar to prevent rubbing
Medication alone cannot correct the prolapse.

If your cat has similar symptoms, please contact your family vet ASAP
==========================================
📌 什麼是貓的第三眼瞼外翻？
第三眼瞼（瞬膜）內有一個 淚腺，負責分泌約 30–40% 的淚液。
當固定腺體的結締組織鬆弛或發炎，腺體會 從內側眼角突出，形成紅色腫塊。

在貓較少見，但仍可能發生，尤其：波斯、異國短毛/眼部慢性炎症/結膜炎或瞬膜鬆弛/罕見的腫瘤或異物刺激

📌 臨床表現
內眼角紅色、圓形腫塊/流淚、眼分泌物增加/結膜炎/眼睛不適、搔抓/有時伴隨瞬膜突出或眼瞼炎

📌 為什麼不能切除腺體？（貓更不能切）
第三眼瞼腺提供大量淚液。
切除會導致 乾眼症（KCS），在貓的治療難度更高，且可能造成：
終身點藥/慢性角膜炎/角膜潰瘍跟視力下降

📌 治療原則
1. 手術復位（標準）
Pocket technique（囊袋法）
Anchoring technique（固定法）
貓的組織較薄、瞬膜較小，手術比狗更精細，但成功率仍高。

2. 藥物輔助
抗生素眼藥
抗發炎眼藥（依醫師判斷）
避免揉眼（伊莉莎白圈）

📌 特別注意：貓的鑑別診斷
貓的第三眼瞼腫塊 不一定是腺體外翻，還可能是：
瞬膜淋巴濾泡增生
結膜炎（病毒性、細菌性）
瞬膜腫瘤（罕見但可能）
異物刺激
瞬膜突出（Horner’s syndrome、疼痛、脫水）

因此貓的第三眼瞼腫塊更需要 獸醫檢查確認是否真的是腺體外翻。

📌 預後
手術成功率高
復發率比狗低
若有慢性結膜炎需同步治療
若延遲治療，腺體可能肥厚、發炎，復位難度增加

如果你的貓咪有類似的症狀,請跟你的家庭獸醫聯絡
