Rare complication of ventriculoperitoneal shunt. Early onset of distal catheter migration into scrotum in an adult male: Case report and literature review

IntroductionThe role of shunt placement is to divert cerebrospinal fluid from within the ventricles to an alternative location in the setting of hydrocephalus. One of the rare shunt complications is distal catheter migration, and various body sites have been reported, including the scrotum. Although cases of scrotal migration of distal catheter have been reported in pediatric patients, cases in adult patients are rare due to obliterated processus vaginalis. Furthermore, there has not been a case reported for scrotal migration in an adult at an early onset.Presentation of case65-year-old male underwent shunt placement for normal-pressure hydrocephalus-like symptoms. On post-operative day seven patient developed right testicular edema, for which ultrasound was performed, revealing hydrocele along with the presence of distal catheter in the scrotum. On post-operative day nine patient underwent distal catheter trimming via laparoscopic approach with general surgery, with post-operative imaging showing satisfactory location of distal catheter in the peritoneal cavity.Discussion/ConclusionEarly onset of distal catheter migration into scrotum in an adult male is a unique case, as most cases are reported in pediatric patients, and it is the first case reported in the English literature to have occurrence at an early onset during the peri-operative period. As our case demonstrates, early occurrence and detection of scrotal migration of the distal catheter prevent shunt malfunction. Prompt surgical management of catheter repositioning is therefore recommended to avoid the risk of further complications.     

Early postoperative colonic ventriculoperitoneal shunt migration with trans-anal protrusion: A unique case report

Introduction and importanceColonic ventriculoperitoneal shunt (VPS) migration with trans-anal protrusion remains uncommon. Patients may be asymptomatic, and diagnosis may only be made on visualization of the prolapsed catheter from the anus. This unique case of early post-operative trans-anal shunt protrusion highlight the possibility of this rare complication specially when shunt revision accompanies bowel surgery.Case presentationThe authors present a case of early postoperative colonic shunt migration in a thirteen-year-old female with who underwent Malone Antegrade Continence Enema (MACE) with concomitant revision of the distal part of the peritoneal catheter. She presented two weeks post operatively with shunt catheter protruding from the anus. This was noticed by her carer and she was asymptomatic on her presentation.Clinical discussionDelayed post-operative shunt related bowel perforation and trans-anal shunt protrusion is an uncommon complication after ventriculoperitoneal shunting. Most cases present months after surgery and majority are asymptomatic on presentation. The exact pathophysiology is not established, and mechanisms have been proposed. Early post -operative trans-anal shunt protrusion is rare and suggests inadvertent occult bowel injury especially when shunt placement or revision accompanies extensive bowel surgery.ConclusionThe authors recommended shunt imaging within the first two to three weeks after shunt revision in patient who undergo concomitant bowel surgery with risk of inadvertent bowel injury to identify early colonic migration and avoid its potentially fatal sequelae.     

Migration of ventriculoperitoneal shunt into the stomach,presenting with gastric bleeding

Summary We present an extremely rare complication after ventriculoperitoneal shunting. The peritoneal tube migrated into the stomach 8 months after the operation and patient presented with gastric bleeding.     

Transoral migration of the inferior end of a ventriculoperitoneal shunt: A case report with literature review

Ventriculoperitoneal (VP) shunt surgery is the most widely used technique for the treatment of hydrocephalus. However, it can incur certain complications. Beside frequent complications (infection, obstruction), migration of the peritoneal catheter is a rare but dangerous complication. This report presents the case of a 4-year-old boy who had undergone VP shunt for hydrocephalus. One month later, the patient presented with protrusion of the peritoneal catheter through his mouth. He underwent another procedure to remove the peritoneal catheter, retaining the original ventricular catheter and valve chamber. Progression was favorable. To the best of our knowledge, only 7 cases of VP shunt transoral extrusion were reported, but many risk factors were identified. Bowel perforation is a serious complication of VP shunt surgery, sometimes leading to fatal outcome.     

Laparoscopic totally extra-peritoneal hernia repair for bilateral Spigelian hernias and coincident inguinal hernia: A case report

IntroductionSpigelian hernia (SH) is a rare ventral hernia occurring near the lateral border of the rectus muscle. The treatment remains controversial and depends on institutional expertise. Although laparoscopic surgery is a good adaptation for the repair of ventral hernias, only a few cases have been reported in the literature. Here, we report a case of totally extra-peritoneal (TEP) repair for bilateral SHs.Presentation of caseA 74-year-old Japanese man presented with asymptomatic bulges in the right lower abdominal quadrant. On physical examination, the bulges were located to the right of the lateral border of the abdominal rectus muscle and the right inguinal region in an upright position. We diagnosed right SH and coincident homonymous ipsilateral inguinal hernia (IH) by abdominal computed tomography and planned a curative operation by laparoscopy. By first laparoscopic exploration, we found an asymptomatic SH to the left of the lateral border of the abdominal rectus muscle and performed TEP repair for all hernias. The second laparoscopic exploration after fixing the mesh in place revealed that the orifice of the right SH was scarred and stiffened by repeated prolapse. We finally eliminated the sac by ligation because of a fear causing of reduction en masse of the SH.Discussion and conclusionThe use of laparoscopy simplified the diagnosis and facilitates the subsequent repair of the hernia. TEP approach is the ideal treatment for the simultaneous laparoscopic repair of SH and IH.

Mesh migration following repair of inguinal hernia: a case report and review of literature

New surgical procedures in the aftermath of their benefits beget new complications as well. Laparoscopic repair of inguinal hernia is widely practised now. It involves reinforcement of hernial defect with a synthetic mesh. We report a rare case of migration of mesh into urinary bladder following this mode of hernial repair. We also present a review of literature involving migration of mesh following all inguinal hernial repairs.     

Early-onset complete spontaneous migration of contraceptive intrauterine device to the bladder in a post C-section patient: A case report

Introduction and importanceSpontaneous migration of a contraceptive intrauterine device (IUD) to the bladder is very rare. It usually takes years for the IUD to migrate completely from the uterine cavity to the bladder. We report a case of early-onset complete spontaneous migration of contraceptive IUD to the bladder in a post C-section patient.Case presentationA 30-year-old woman presented with suprapubic pain and dysuria three weeks prior to hospitalization. She had C-section three months prior and underwent copper IUD insertion two months after the surgery. One week after IUD insertion, radiography showed that the IUD remained in the uterus, but the patient felt suprapubic pain and dysuria. Computed tomography (CT) three weeks after IUD insertions showed IUD migration to the bladder with its tips embedded in the uterine wall. Cystoscopy was performed one week later and the IUD was completely inside the bladder. By then, the IUD was removed completely via forceps with no complication.Clinical discussionThe exact pathophysiology of spontaneous IUD migration is unknown, but migration always starts with uterine perforation. In our case, uterine perforation was probably caused by immediate traumatic perforation. CT is the preferred radiological examination. IUD removal was performed one month after IUD insertion showing complete migration of the IUD, though CT one week prior suggested that the tips of the IUD remained embedded.ConclusionIn cases of early-onset complete spontaneous migration of contraceptive IUD to the bladder, CT is the preferred radiological examination, and delaying removal procedure may be beneficial.     

Neurological recovery across a 2-cm gap of radial nerve repair using end to end suture following supracondylar humerus fracture: Case report

Introduction and ImportanceTraumatic laceration of the radial nerve following supracondylar humerus fracture in the pediatric population is highly uncommon. Transection of the radial nerve is rare, and approximately 12.7% of all nerve injuries are categorized as neurapraxia that will resolve spontaneously.Case presentationWe report a rare case of a 9-year-old boy presented with a right wrist drop after fell on an outstretched hand two weeks before. The radiological finding revealed a posteriorly displaced supracondylar humerus fracture. Intraoperatively, we found the radial nerve had lost its continuity and interposed by fibrotic tissue. We resect and do a direct repair of the nerve along with fixation of the fracture. At 4-months postoperative follow-up, the patient could fully extend his right thumb and wrist but retain a tingling sensation in the radial nerve distribution. At 1-year follow up the motor and sensory functions were normal without any complication.Clinical DiscussionTransection of radial nerve following the supracondylar fracture represents a rare case. The radial nerve was transected and interposed by scar tissue at the fracture site level, preventing spontaneous nerve regeneration. In a case of nerve transection, surgical repair is indicated.ConclusionIn the case of supracondylar humerus fracture with posterior displacement, radial nerve transection could be associated with injuries. Authors favour nerve exploration with fracture stabilization performed as soon as possible when nerve injury is suspected. Appropriately managed, the outcome in the pediatric population is highly favourable.     

When laparoscopy for fertility preservation prior to gonadotoxic treatment of an anterior mediastinal mass is a dilemma: A case report

IntroductionThe management of anterior mediastinal masses is a challenge for anesthesiologists. Recommendations for their management in the context of diagnostic or curative surgery are well described. The added risk of laparoscopic surgery for fertility preservation has however never been discussed in the literature.Presentation of caseWe present the case of a 32-year-old female patient with a large malignant anterior mediastinal mass. She was referred for anesthesia evaluation before laparoscopic ovarian tissue harvesting as part of fertility preservation prior to gonadotoxic treatment. The patient presented dyspnea at rest. Chest computed tomography revealed a tracheal deviation and a partial obstruction of the left mainstem bronchus. Transthoracic echocardiography showed a pericardial effusion. Proceeding to high risk anesthesia for a non-curative surgery in a patient with a highly symptomatic mass was considered unacceptable and the procedure was postponed. The patient received a single cycle of neoadjuvant chemotherapy. Clinical and radiological improvement were shown after this single dose and laparoscopic surgery was performed under general anesthesia without complications.ConclusionIn the context of an anterior mediastinal mass and fertility preservation a thorough benefit-risk analysis must be undertaken before non-curative laparoscopic surgery. In case of severe symptoms, surgery should be postponed until the patient’s condition improves after the minimum necessary chemotherapy treatment. So far it is impossible to say whether the risk exceeds the expected benefit in this difficult situation. Further studies need to be conducted in this area.     

Robot-assisted laparoscopic repair of perineal hernia after abdominoperineal resection: A case report and review of the literature

IntroductionPerineal hernia is a protrusion of the pelvic floor containing intra-abdominal viscera. The occurrence of postoperative perineal hernia after abdominoperineal resection (APR) is rare, but reports have indicated a recent increase in occurrence following surgical treatment for rectal cancer. This has been attributed to a shift towards extralevator abdominoperineal resection, together with more frequent and long-term use of neoadjuvant therapy.Presentation of caseHere, we report the case of a patient who underwent APR for cancer. Twenty months postoperative, a perineal hernia was detected. The patient was electively scheduled for surgery. Robot-assisted laparoscopy was performed using the da Vinci Surgical System. The perineal hernia was repaired by primary closure with the placement of Symbotex Composite mesh as reinforcement for the pelvic floor. The surgery was performed without any adverse events, and the patient was discharged the day after surgery. Clinical follow-up proceeded at the designated time intervals without difficulties.DiscussionRecurrence rates of perineal hernia remain high, and surgeons face numerous challenges related to poor view, suturing and mesh placement in the deep pelvis. Numerous approaches have been described, but there is still no consensus as to the optimal repair technique for perineal hernia.ConclusionSymptomatic perineal hernias can feasibly be repaired with robot-assisted laparoscopy. Furthermore, suturing and mesh placement require less effort with the robot approach when compared to the open and laparoscopic approaches. These promising findings are demonstrated in the included video.     

Extra luminal migration of ingested fish bone to the spleen as an unusual cause of splenic rupture: Case report and literature review

IntroductionThe ingestion of foreign bodies (FB) is a common problem worldwide and affects all ages; it is, however, particularly important in the pediatric population and in mentally impaired adults. The typical outcome of FB ingestion is good, since the majority of ingested material is passed spontaneously through the gastrointestinal tract. Serious complications can occur, however, including bowel perforation or obstruction and gastrointestinal bleeding, amongst others. Extraluminal migration of ingested foreign bodies is very rare and reported cases so far have shown, more commonly, migration to neck structures, with very few reported cases of migration to the abdomen. To date, there is no reported case of extraluminal migration of ingested FB to the spleen.Case presentationA 59-year-old man presented with acute abdominal pain and dyspnea. A CT scan revealed a FB within the spleen, with a ruptured capsule and perisplenic collection. Surgery was performed and a 3cm-long fishbone was extracted, with hemoperitoneum secondary to spleen rupture. The patient was discharged on the third postoperative day with good recovery and without any complications; pneumococcal polysaccharide vaccination was provided.ConclusionFB ingestion is a relatively benign condition; however, some serious complications can arise infrequently. The patient reported herein is the first in the literature to present a splenic rupture due to extra luminal migration of an ingested fish bone.     

Papillotubular carcinoma with an invasive micropapillary carcinoma component of the breast,characterized by a rapid increase in size due to intra-tumoral hemorrhage: A case report

IntroductionRapidly enlarging mammary tumors, including invasive breast tumors, are clinically rare. Invasive micropapillary carcinoma (IMPC) of the breast is known to have aggressive behavior and poor clinical course compared to invasive ductal carcinoma.Case presentationAn 87-year-old woman presented with a rapidly enlarging tumor of the right breast over the course of 3 weeks. Ultrasonography and computed tomography of the chest revealed a giant tumor located on the right chest wall, with heterogeneous parenchymal components and several cystic lesions. Emergency mastectomy was performed because of rapid tumor enlargement complicated by hemorrhage. Histopathological diagnosis confirmed a papillotubular invasive ductal carcinoma with an IMPC component. Tumor cells were negative for estrogen and progesterone receptors, and the human epidermal growth factor receptor 2 score was 2+.DiscussionThere has been only one report of breast carcinoma with rapid enlargement caused by spontaneous intratumoral hemorrhage to date. IMPC is associated with a high incidence of axillary lymph node metastases, frequent local recurrence, and a poor clinical outcome. In the present case, the specific breast cancer type can be considered as potential factors responsible for hemorrhage induction within the tumor that further enhanced rapid tumor growth.ConclusionIMPC is a rare, clinically aggressive variant of invasive ductal carcinoma. Owing to its aggressive clinical behaviors, surgeons should readily recognize the morphology of IMPC.     

New technique for the management of anteriorly located midline prostatic cysts causing severe lower urinary tract symptoms: Case report and literature review

IntroductionProstatic cysts are uncommon and usually asymptomatic. In most cases, these cysts are found incidentally by imaging. In some cases, these cysts can be symptomatic and missed for years.Case reportWe report the case of a 36-year-old male patient presented with a 3-year history of weak urine stream, dysuria, frequency and urgency. Ultrasound, computed tomography and magnetic resonance imaging demonstrated a prostatic cyst measuring 1.5*1.2 cm occupying the bladder outlet and causing obstruction. Transverse incision of the cyst provided a satisfactory resolution of the patient’s complaint.ConclusionIncision of a symptomatic midline anterior prostatic cyst is a safe and effective management option with no potential risk of retrograde ejaculation.     

Intra-abdominal abscess due to patient non-compliance after construction of an ileal neobladder: Case report and review of the literature

PURPOSE: A case report of patient with an intra-abdominal abscess 8 weeks after radical cystectomy and construction of an ileal neobladder is presented. METHODS/RESULTS: The patient was admitted with nausea, vomiting and singultus. A perforation of the neobladder due to overdistension was assumed to be the underlying cause of the intra-abdominal abscess formation as the patient admitted infrequent voiding during the day and no emptying of the neobladder at night. The patient underwent explorative laparotomy and 4200 mL of pus was removed from the abdominal cavity. The patient made an uneventful recovery and was discharged from hospital after 5 weeks. Neobladder function remained stable and the patient was leading a normal life at 24 months follow-up. CONCLUSIONS: The present case demonstrates the need for careful patient selection prior to radical cystectomy with continent urinary diversion. Reduced compliance and mental disabilities of a patient can increase the complication rate.     

Diagnostic pitfall: Adenoid cystic carcinoma of the tongue presenting as an isolated hypoglossal nerve palsy,case report and literature review

IntroductionWe describe a patient with an unusual presentation of an isolated hypoglossal nerve palsy as a result of perineural invasion (PI) from adenoid cystic carcinoma (ACC). We will also discuss the diagnostic pitfalls as well as present a short literature review of adenoid cystic carcinomas and suggest improvement to the current diagnostic algorithm for isolated hypoglossal nerve palsies.Presentation of caseA 63 year old Malay female presented with progressive dysphagia and slurred speech for one year. Physical examination showed unilateral right tongue wasting, fasciculation and deviation to the right. An MRI showed atrophy of the tongue due to denervation and subsequently she was treated in a neurology clinic for 8 months.Due to lack of improvement, she was referred to our surgical unit and underwent examination under anaesthesia (EUA) and biopsy. Histology showed adenoid cystic carcinoma with perineural involvement, resulting in lower motor neuron signs.She underwent radiotherapy to the base of her tongue (70 Gy/35#). A PET-CT one month post treatment showed complete response.DiscussionAdenoid cystic carcinoma (ACC) is a salivary gland neoplasm. It is characterized by local invasiveness with frequent recurrence and indolent growth. It affects major salivary glands more than minor salivary glands.In malignancies that have a propensity for PI such as ACC, patients may present atypically with nerve palsies. In infiltrative lesions, the primary tumour may not be evident on magnetic resonance imaging. Therefore, to achieve a diagnosis, a high index of suspicion is required. When the diagnosis is in question, deep biopsy and positron emission tomography may be useful.     

Randomized,controlled, blinded trial of Tissucol/Tisseel for mesh fixation in patients undergoing Lichtenstein technique for primary inguinal hernia repair: rationale and study design of the TIMELI trial

Background Complications associated with sutured mesh fixation following open groin hernia repair have prompted surgeons to evaluate methods of atraumatic fixation such as the use of human fibrin glue. Small trials with Tissucol/Tisseel fibrin glue (Baxter Healthcare, Deerfield, IL, USA) have shown promising results that warrant further investigation. Methods TIMELI (Tissucol/Tisseel for MEsh fixation in LIchtenstein hernia repair) is an international, controlled, randomized, patient- and evaluator-blinded study that is comparing mesh fixation with Tissucol or sutures in patients with inguinal hernia. The primary endpoint evaluates the incidence of disabling complications (chronic pain and/or numbness and/or groin discomfort) at 12 months post-surgery. Results Patient enrolment started in February 2006 and ended on 19 April 2007, with a total of 325 patients recruited. Initial results are expected in early 2008. Conclusions TIMELI is a major international trial that will provide important information on the efficacy and safety of Tissucol, compared with sutures, for mesh fixation in patients undergoing Lichtenstein technique for primary inguinal hernia repair.
