Diskectomy 
Medical specialty:  Orthopedic
 Redo L4-5 diskectomy, left - recurrent herniation L4-5 disk with left radiculopathy.

PREOPERATIVE DIAGNOSIS (ES):, Recurrent herniation L4-5 disk with left radiculopathy.,POSTOPERATIVE DIAGNOSIS (ES):, Recurrent herniation L4-5 disk with left radiculopathy.,PROCEDURE:, Redo L4-5 diskectomy left.,COMPLICATIONS:, None.,ANTIBIOTIC (S),: Vancomycin given preoperatively.,ANESTHESIA:, General endotracheal.,ESTIMATED BLOOD LOSS:, 10 mL.,BLOOD REPLACED:, None.,CRYSTALLOID GIVEN:, 800 mL.,DRAIN (S):, None.,DESCRIPTION OF THE OPERATION:, The patient was brought to the operating room in supine position. General endotracheal anesthesia was administered. He was turned into the prone position on the operating table and positioned in the modified knee-chest position with Andrews frame being used. Care was taken to protect pressure points. The back was shaved, scrubbed with Betadine scrub, rinsed with alcohol, and prepped with DuraPrep, and draped in the usual sterile fashion with Ioban drape being used. A midline skin incision was made, excising scar from previous surgery. Dissection was carried down through the subcutaneous tissue with electrocautery technique. The lumbosacral fascia was split to the left of the spinous process, and subperiosteal dissection of the spinous process and lamina, area of previous laminotomy was identified. Cross-table lateral was also made to confirm position. The scar was then loosened from the inferior portion of 4, superior of L5 lamina, and a portion of the lamina was removed. I did identify normal dura. The scar was then lysed from the medial wall. Dura and nerve root were identified and protected with nerve root retractor. The bulging disk fragment was still contained under the longitudinal ligament. A rent was made with the Penfield and a moderately large fragment was removed. The disk space was then entered with a cruciate cut in the annulus, with additional nuclear material being received. When no other fragments could be removed from the disk space, no other fragments were felt in the central canal under the longitudinal ligament, and a Murphy ball could be passed through the foramen without evidence of compression, the decompression was complete. Check was made for CSF leakage, and no evidence of significant epidural bleeding was present. The wound was irrigated with antibiotic solution. Twenty milligrams of Depo-Medrol was placed over the dura and nerve root. A free fat graft from the subcutaneous tissue was then placed over the dura. Closure was obtained with the lumbosacral fascia being reapproximated with #1, running, Vicryl suture. Subcutaneous closure was obtained in layers with 2-0, running, Vicryl suture. Skin closure was obtained with 3-0 Vicryl subcuticular suture. Proxi-Strips and sterile dressing was applied. The skin had been infiltrated with 8 mL of 0.5% Marcaine with epinephrine.,After a sterile dressing was applied, the patient was turned into the supine position on the waiting recovery room stretcher, brought from under the effects of anesthesia, and taken to the recovery room.
de Quervain Release - Wrist

 Wrist de Quervain stenosing tenosynovitis.  de Quervain release.  Fascial lengthening flap of the 1st dorsal compartment.

PREOPERATIVE DIAGNOSIS:,  Wrist de Quervain stenosing tenosynovitis.,POSTOPERATIVE DIAGNOSIS: , Wrist de Quervain stenosing tenosynovitis.,TITLE OF PROCEDURES,1. de Quervain release.,2.  Fascial lengthening flap of the 1st dorsal compartment.,ANESTHESIA:,  MAC.,COMPLICATIONS: , None.,PROCEDURE IN DETAIL: , After MAC anesthesia and appropriate antibiotics were administered, the upper extremity was prepped and draped in the usual standard fashion.  The arm was exsanguinated with an Esmarch and the tourniquet inflated to 250 mmHg.,I made a transverse incision just distal to the radial styloid.  Dissection was carried down directly to the 1st dorsal compartment with the superficial radial nerve identified and protected.  Meticulous hemostasis was maintained with bipolar electrocautery.,I dissected the sheath superficially free of any other structures, specifically the superficial radial nerve.  I then incised it under direct vision dorsal to its axis and incised it both proximally and distally.  The EPB subsheath was likewise released.,I irrigated the wound thoroughly.  In order to prevent tendon subluxation, I then back-cut both the dorsal and volar leafs of the sheath so that I could close them in an extended and lengthened position.  I did this with 3-0 Vicryl.  I then passed an instrument underneath to check and make sure that the sheath was not too tight.  I then irrigated it and closed the skin, and then I dressed and splinted the wrist appropriately.  The patient was sent to the recovery room in good condition, having tolerated the procedure well.
Diskectomy & Fusion

PREOPERATIVE DIAGNOSIS: , Degenerative disk disease at L4-L5 and L5-S1.,POSTOPERATIVE DIAGNOSIS:,  Degenerative disk disease at L4-L5 and L5-S1.,PROCEDURE PERFORMED:  ,Anterior exposure diskectomy and fusion at L4-L5 and L5-S1.,ANESTHESIA: , General.,COMPLICATIONS:,  None.,ESTIMATED BLOOD LOSS: , 150 mL.,PROCEDURE IN DETAIL:  ,Patient was prepped and draped in sterile fashion.  Left lower quadrant incision was performed and taken down to the preperitoneal space with the use of the Bovie, and then preperitoneal space was opened.  The iliac veins were carefully mobilized medially, and then the L4-L5 disk space was confirmed by fluoroscopy, and diskectomy fusion, which will be separately dictated by Dr. X, was performed after the adequate exposure was gained, and then after this L4-L5 disk space was fused and the L5-S1 disk space was carefully identified between the iliac vessels and the presacral veins and vessels were ligated with clips, disk was carefully exposed.  Diskectomy and fusion, which will be separately dictated by Dr. X, were performed.  Once this was completed, all hemostasis was confirmed.  The preperitoneal space was reduced.  X-ray confirmed adequate positioning and fusion.  Then the fascia was closed with #1 Vicryl sutures, and then the skin was closed in 2 layers, the first layer being 2-0 Vicryl subcutaneous tissues and then a 4-0 Monocryl subcuticular stitch, then dressed with Steri-Strips and 4 x 4's.  Then patient was placed in the prone position after vascular checks of the lower extremity confirmed patency of the arteries with warm bilateral lower extremities.

PREOPERATIVE DIAGNOSIS,1.  Carpal tunnel syndrome.,2. de Quervain's stenosing tenosynovitis.,POSTOPERATIVE DIAGNOSIS,1.  Carpal tunnel syndrome.,2. de Quervain's stenosing tenosynovitis.,TITLE OF PROCEDURE,1.  Carpal tunnel release.,2. de Quervain's release.,ANESTHESIA: , MAC,COMPLICATIONS: , None.,PROCEDURE IN DETAIL:  ,After administering appropriate antibiotics and MAC anesthesia, the upper extremity was prepped and draped in the usual standard fashion.  The arm was exsanguinated with Esmarch and the tourniquet inflated to 250 mmHg.,A longitudinal incision was made in line with the 4th ray, from Kaplan's cardinal line proximally to 1 cm distal to the volar wrist crease.  The dissection was carried down to the superficial aponeurosis.  The subcutaneous fat was dissected radially from 2-3 mm and the superficial aponeurosis cut on this side to leave a longer ulnar leaf.,The ulnar leaf of the cut superficial aponeurosis was dissected ulnarly, and the distal edge of the transverse carpal ligament was identified with a hemostat.  The hemostat was gently placed under the transverse carpal ligament to protect the contents of the carpal tunnel, and the ligament was cut on its ulnar side with a knife directly onto the hemostat.  The antebrachial fascia was cut proximally under direct vision with scissors.,After irrigating the wound with copious amounts of normal saline, the radial leaf of the cut transverse carpal ligament was repaired to the ulnar leaf of the cut superficial aponeurosis with 4-0 Vicryl.  Care was taken to avoid entrapping the motor branch of the median nerve in the suture.  A hemostat was placed under the repair to ensure that the median nerve was not compressed.  The skin was repaired with 5-0 nylon interrupted stitches.,The first dorsal compartment was addressed through a transverse incision at the level of the radial styloid tip.  Dissection was carried down with care taken to avoid and protect the superficial radial nerve branches.  I released the compartment in a separate subsheath for the EPB on the dorsal side.  Both ends of the sheath were released to lengthen them, and then these were repaired with 4-0 Vicryl.  It was checked to make sure that there was significant room remaining for the tendons.  This was done to prevent postoperative subluxation.,I then irrigated and closed the wounds in layers.  Marcaine with epinephrine was placed into all wounds, and dressings and splint were placed.  The patient was sent to the recovery room in good condition, having tolerated the procedure well.

FINDINGS:,There is a well demarcated mass lesion of the deep lobe of the left parotid gland measuring approximately 2.4 X 3.9 X 3.0cm (AP X transverse X craniocaudal) in size. The lesion is well demarcated. There is a solid peripheral rim with a mean attenuation coefficient of 56.3. There is a central cystic appearing area with a mean attenuation coefficient of 28.1 HU, suggesting an area of central necrosis. There is the suggestion of mild peripheral rim enhancement. This large lesion within the deep lobe of the parotid gland abuts and effaces the facial nerve. Primary consideration is of a benign mixed tumor (pleomorphic adenoma), however, other solid mass lesions cannot be excluded, for which histologic evaluation would be necessary for definitive diagnosis. The right parotid gland is normal.,There is mild enlargement of the left jugulodigastric node, measuring 1.1cm in size, with normal morphology (image #33/68). There is mild enlargement of the right jugulodigastric node, measuring 1.2cm in size, with normal morphology (image #38/68).,There are demonstrated bilateral deep lateral cervical nodes at the midlevel, measuring 0.6cm on the right side and 0.9cm on the left side (image #29/68). There is a second midlevel deep lateral cervical node demonstrated on the left side (image #20/68), measuring 0.7cm in size. There are small bilateral low level nodes involving the deep lateral cervical nodal chain (image #15/68) measuring 0.5cm in size.,There is no demonstrated nodal enlargement of the spinal accessory or pretracheal nodal chains.,The right parotid gland is normal and there is no right parotid gland mass lesion.,Normal bilateral submandibular glands.,Normal parapharyngeal, retropharyngeal and perivertebral spaces.,Normal carotid spaces.,IMPRESSION:,Large, well demarcated mass lesion of the deep lobe of the left parotid gland, with probable involvement of the left facial nerve. See above for size, morphology and pattern enhancement. Primary consideration is of a benign mixed tumor (pleomorphic adenoma), however, other solid mass lesions cannot be excluded, for which histologic evaluation is necessary for specificity.,Multiple visualized nodes of the bilateral deep lateral cervical nodal chain, within normal size and morphology, most compatible with mild hyperplasia.
