Laparoscopic surgery is a technically demanding procedure that requires a significant level of experience and expertise. Since surgery is the mainstay treatment of rectal cancer, comprehending the complexities of multilaminar structures and interfascial spaces is imperative.
This is the case of a 68-year-old woman who was evaluated for a positive fecal occult blood test. Colonoscopy found a vegetative lesion 15 cm from the anal verge, occupying ~1/2 of the lumen. Biopsy and distal tattooing were performed. Pathology study confirmed the presence of a moderately differentiated adenocarcinoma.
The CT-scan showed no lung or liver metastasis. MRI revealed an upper rectal cancer, 11.4 cm from the anal verge, with no pathological lymph nodes, staged as cT2 N0 Mx CRM-.
After discussion in a multidisciplinary meeting, a laparoscopic anterior rectal resection was proposed.
By segmentation of the surgery into well-organized stages, this video demonstrates all the important technical steps to fasten the learning curve and master the procedure without compromising the oncologic principles.
In this video we present the case of a 98 year old chinese gentleman who presented to the emergency department for 2 days of painful right groin lump. He has a history of bilateral inguinal hernia for many years, but declined surgery. Otherwise, his past medical history includes degenerative disc disease, osteoporosis and hearing impairment. On presentation, he was able to tolerate oral feeding with no nausea or vomiting and still able to pass stools. On examination, there was a large and tender right irreducible inguinal hernia with overlying erythema and warmth. There was also a small left inguinal hernia that was reducible. CT Abdomen-Pelvis was done and showed an incarcerated right inguinal hernia containing a loop of sigmoid colon with poor enhancement of the bowel wall. The colon proximal to the incarcerated segment was also mildly dilated.
Patient underwent urgent repair of the strangulated right inguinal hernia via laparoscopic, transabdominal preperitoneal (TAPP) approach. Intra-operatively, a loop of sigmoid colon was incarcerated within a direct right inguinal hernia. A small colotomy had to be made to decompress the incarcerated loop in view of difficulty in reducing the sigmoid colon. After reduction, the incarcerated segment was gangrenous and non-viable requiring sigmoid colectomy with primary anastomosis. Pantaloon inguinal hernias with femoral hernias were seen over bilateral groins. An Ultrapro 10x15cm composite mesh was inserted over bilateral groins with adequate medial overlap ensured.
The operation took three hours and fifty minutes with minimal blood loss. Drain was removed and feeding was escalated to diet on post-operative day four. Patient was able to pass stools and then discharged on post-operative day six. His case was complicated with a small 2cm seroma at the right groin.
A 75-year-old male with history of chronic HCV- related hepatitis, in regular follow-up and sustained viral response (SVR), presented at our Emergency Department for sudden epigastric pain. Urgency CT scan and subsequent abdominal MRI revealed a 2,5cm monofocal HCC in S5 with surrounding hepatic hematoma (7cm of extension) and hemoperitoneum layer. The procedure consisted in laparoscopic exploration, lysis of tenacious adhesions between hepatic hematoma and the right colic flexure, intraoperative ultrasound to assess tumor extension, preparation of Pringle Maneuver and parenchyma transection with ultrasound dissector combined with colecistectomy.
A 47-year-old male, with a history of multiple cholelithiasis and multiple choledochal lithiasis, who presented with multiple episodes of cholangitis for which endoscopic treatment (ERCP + stenting) was performed. After 4 unsuccessful attempts to resolve the bile duct by endoscopic approach, it was decided to perform minimally invasive laparoscopic surgery.
In this video we can observe the Choledochotomy, followed by extraction of stones and biliary mud. Subsequently, a choledochoscopy is performed with the laparoscopic camera (10 mm) with infusion of sterile Physiological Solution since the patient had a very dilated bile duct. Choledochorrhaphy is then performed.
The surgical management of rectovaginal fistulas remains difficult, as they tend to be recurrent and vary widely in location and complexity. We present a case of a 63-year-old woman with a low-lying rectovaginal fistula who initially underwent chemoradiation and a Low Anterior Resection for a low-lying rectal cancer. Her course was uneventful until two years post-operatively, at which time her anastomotic staple line became stenotic with associated bleeding. This was initially addressed by Gastroenterology who executed a dilation and achieved hemostasis with Argon Plasma Coagulation. This remedied the stenosis, however, it was complicated by the formation of a rectovaginal fistula. Due to the low-lying location and its presence in an irradiated field, a transvaginal approach with an interposed gracilis flap was elected for repair.
This video demonstrates how to place the pelvic binder quickly and correctly, which may be life-saving in cases of pelvic ring fractures with associated potential massive bleeding. Proper pelvic binder placement technique requires attention to some details, including the 5Ps (pulses, penis, pockets, pain and pulses), horizontal force application in opposing vectors and ensuring the pelvic binder is locked.
Donghang Huang’s procedure, also termed as direct-access single-port endoscopy assisted mini-incision thyroidectomy, is a hybrid surgery conducted in the following 3 major steps:
1.A mini-incision of approximately 2.5-3 cm long on the central neck is made. A working space under the platysmal muscle or strap muscles for single-port endoscopic surgery is constructed with carbon dioxide insufflation (performed under direct vision).
2.Mobilization of the superior and inferior pole of the thyroid lobe, and exposure of the recurrent laryngeal nerve (performed under single-port endoscopy).
3.Extraction and resection of the thyroid lobe. (performed under direct vision).
Donghang Huang’s procedure can provide shorter incision and better cosmetic results while maintaining adequate exposure.
Paediatric Tracheostomy
Position the child with chin extension appropriately
Drape the child as shown in the video
Mark the incision line
Use 15 number blade for skin incision
Remove the excessive subcutaneous fat tissue
Find the median raphe and strap muscles
Retract the strap muscles laterally
Identify the tracheal ring
Create the impression of tube for appropriate size incision
Place the stay sutures as shown in the video
incise the trachea with 11 number blade
Secure the maturation sutures
Insert the tracheostomy tube
Confirm the position and then inflate the cuff
Secure the ties and dressing at the end.
Stoma prolapse is an increase in the size of the stoma secondary to intussusception of the proximal bowel segment. Strangulation and ischemia of the prolapsed segment have been reported as complications.
This is the case of a 58-year-old man with multiple comorbidities who was diagnosed with an adenocarcinoma of the ascending colon with hepatic metastasis. He was considered unable to start conversion chemotherapy because of his cardiovascular comorbidities and was therefore under paliative chemotherapy.
Patient came into emergency room with an acute bowel obstruction and underwent a loop ileostomy as a diversion procedure. Following up the procedure, the patient developed an acute on chronic kidney failure because of dehydration from high output ileostomy. In the postoperative day 17, patient presented with an acutely incarcerated prolapsed afferent limb of the loop ileostomy. Attempts at reduction were unsuccessful.
Herein we present a simple, safe, and fast approach for correcting a prolapsed loop or terminal stoma using a step-wise application of linear staplers.
When laparotomy and/or stoma reversal is not appropriate, local revision of stoma prolapse provides a low-risk and high-benefit alternative solution.
