Laparoscopic liver resection of segment seven: A case report and review of surgical techniques.

ABSTRACT:

Introduction

Laparoscopic liver resection of segment seven (LLR-S7) is a technically challenging procedure due to its anatomical location and difficult accessibility. Herein, we present our experience with LLR-S7, and demonstrate a literature review regarding surgical techniques.

Presentation of case

A 28-year-old female was diagnosed with rectosigmoid cancer and synchronous liver metastases at the segment three (S3) and S7, which were treated with laparoscopic procedure. After the completely mobilization of the right lobe, the Glissonean pedicle of S7 (G7) was intrahepatically transected. The right hepatic vein was exposed to identify the venous branch of S7 (V7). Finally the liver parenchyma between RHV and dissection line was divided.

Discussion

Various laparoscopic approaches for S7 have been reported including the Glissonian approach from the hilum, the intrahepatic Glissonean approach, the caudate lobe first approach, and the lateral approach from intercostal ports. To perform LLR-S7 safely, it is important to understand the advantage of each technique including the trocar placement and approaches to S7 by laparoscopy.

Conclusion

We present our experience of LLR-S7 for the tumor located at the top of S7, successfully performed with the intrahepatic Glissonean approach. LLR-S7 can be performed safely with advanced laparoscopic techniques and sufficient knowledge on various approaches for S7.

Laparoscopic resection of a paraganglioma behind the retrohepatic segment of the inferior vena cava: a case report and literature review.

Project description:BackgroundDue to the location of paragangliomas (PGLs) behind the retrohepatic segment of inferior vena cava (IVC), it is difficult to expose and resect the tumor.Case presentationA tumor measuring 50×45×62cm behind the retrohepatic portion of IVC was found in a 51-year-old female with hypertention and diabetes mellitus. Although the test for catecholamines revealed no signs of disease, the enhanced computed tomography (CT) scan, somatostatin receptor imaging and iodine-131-labeled metaiiodo-benzylguanidine (131I-MIBG) imaging revealed that the tumor was PGL. A three-dimensional printing was performed to visualize the tumor. The laparoscpic surgery for the PGL behind the retrohepatic segment of IVC was performed and the tumor was resected completely without causing any tissues injury. The pathologic diagnosis was PGL and the patient was able to recover well.ConclusionsThis case demonstrates that laparoscopic surgery may be helpful in tumor accessibility, and could be used in the appropriate cases to remove PGLs that are located behind the retrohepatic segment of the IVC.

Laparoscopic resection of a primary diaphragmatic schwannoma: a case report and literature review.

Project description:BACKGROUND:Schwannomas are nerve sheath tumors that commonly originate from the stomach and small intestine. A primary schwannoma of the diaphragm is rare and does not show any symptoms until it grows to a certain size. Hence, it is extremely rare that it was found at a size that allowed resection under videoscopic surgery. CASE PRESENTATION:A 77-year-old woman was referred to our department for surgical treatment of a tumor located near the gastric fornix. She underwent a routine esophagogastroduodenoscopy 2 years and 7 months prior to the referral. It was suspected that she had a submucosal tumor measuring 10 mm, located in the fornix, and was then referred to her previous physician. During her follow-up, endoscopic ultrasonography (EUS) revealed that the cystic structure had continued to grow toward the gastric wall, and she was then referred to the endoscopy division of our hospital. She continued to be followed-up, and it was noted that the tumor was gradually increasing in size. Therefore, she requested surgical resection, and was finally referred to our division. Since the tumor was rather small, we planned a laparoscopic surgery. An initial examination during the operation revealed that the tumor was located on the left diaphragm. Since the tumor was relatively small and visibility was good, we decided to continue with the laparoscopic surgery. Partial diaphragmectomy with complete inclusion of the tumor was performed, and the defect of the diaphragm was directly closed by a running suture. Pathological examination revealed a benign schwannoma that had originated from the diaphragm. To support our findings, we also reviewed the scientific literature on diaphragmatic schwannoma cases reported up to April 2020. CONCLUSIONS:In this extremely rare case, we successfully resected the diaphragmatic schwannoma using laparoscopic surgery.

New surgical technique of laparoscopic resection of adenomyosis under real-time intraoperative ultrasound elastography guidance: A case report.

Project description:Detecting adenomyosis in the myometrium is a challenge since it is infiltrative with ill-defined margins and can be often confused with uterine fibroids. However, recent advances, such as ultrasound elastography, have enabled its detection in the myometrium, thereby facilitating its accurate diagnosis. We report our experience of performing complete laparoscopic resection of adenomyosis under real-time ultrasound elastography guidance in a 32-year-old woman who underwent laparoscopic adenomyomectomy following severe dysmenorrhea and heavy menstrual bleeding. Real-time ultrasound elastography was also utilized intraoperatively to detect residual adenomyosis. Complete adenomyosis resection and uterine reconstruction were achieved. Follow-up magnetic resonance imaging was conducted to confirm successful uterine reconstruction. The patient recovered rapidly with no complications. Intraoperative elastography-guided laparoscopic adenomyomectomy was feasible and effective in completely removing adenomyotic lesions.

Laparoscopic resection of retroperitoneal intra-psoas muscle schwannoma: A case report and extensive literature review.

Project description:INTRODUCTION:Soft tissue tumors of Schwann cells in either the peripheral or cranial nerves are known as schwannomas or also as neurilemmomas. Limited data exists regarding psoas muscle schwannoma in the literature. Therefore, we have done an extensive literature review and found a total number of 46 cases of intra-psoas schwannoma including our case, which are summarized in this article along with reporting our new case. PRESENTATION OF CASE:We report a very rare case of primary left intra-psoas muscle schwannoma in a 39-year-old Saudi gentleman, smoker with an unremarkable medical and surgical history. The patient presented to the emergency department with exacerbated chronic lower abdominal pain since almost 2 years. After conforming the diagnosis, the patient was admitted electively and underwent uneventful laparoscopic hand-assisted resection. DISCUSSION:Schwannomas are neurogenic tumors which known to be solitary, benign, well circumscribed, encapsulated, and slow-growing tumors. Multiple imaging modalities are used to detect such a tumor. Although there is no consensus on the best surgical approach, endoscopic mini-laparotomy, laparoscopy (anterior [as in our case] or lateral), and robotic resection were reported with good outcomes. CONCLUSION:Retroperitoneal schwannoma and intra-psoas muscle variant are a rare entity, with slow growing rate and risk of malignant transformation. Therefore, high index of suspicion, good follow-up, and large-cohort studies are encouraged.

Regional techniques for pain management following laparoscopic elective colonic resection: A systematic review.

Project description:IntroductionPain management is an integral part of Enhanced Recovery After Surgery (ERAS) following laparoscopic colonic resection. A variety of regional and neuraxial techniques were proposed, but their efficacy is still controversial. This systematic review evaluates published evidence on analgesic techniques and their impact on postoperative analgesia and recovery for laparoscopic colonic surgery patients.MethodsWe conducted bibliographic research on May 10, 2021, through PubMed, Cochrane database, and Google scholar. We retained meta-analysis and randomized clinical trials. We graded the strength of clinical data and subsequent recommendations according to the Oxford Centre for Evidence-Based Medicine.ResultsTwelve studies were included. Thoracic epidural analgesia improved postoperative analgesia and bowel function following laparoscopic colectomy. However, it lengthens the hospital stay. Transversus abdominis plane block was as effective as thoracic epidural analgesia concerning pain control but with better postoperative recovery and lower length of hospital stay. Moreover, Lidocaine intravenous infusion improved postoperative pain management and recovery; Quadratus lumborum block provided similar postoperative analgesia and recovery. Finally, wound infiltration reduced postoperative pain without improving recovery of bowel function, and it could be proposed as an alternative to thoracic epidural analgesia.ConclusionsSeveral analgesic techniques have been investigated. We found that abdominal wall blocks were as effective as thoracic epidural analgesia for pain management but with lower hospital stay and better recovery. We registered this review on PROSPERO (ID: CRD42021279228).

Surgical resection of a giant pericardial cyst: a case report.

Project description:BackgroundPericardial cysts are rare congenital mediastinal cysts. They are typically asymptomatic and are often discovered incidentally, although some patients may present with chest pain and dyspnoea. Asymptomatic patients are managed conservatively with multiple modalities, with surgical resection often recommended for symptomatic patients only. The frequency of follow-up imaging has yet to be established.Case summaryWe report a case of a 59-year-old female with a gradually increasing pericardial cyst, first noted 10 years prior as an abnormal cardiac silhouette on routine chest radiography. Further evaluation confirmed the presence of a pericardial cyst compressing the left ventricle with new-onset atrial fibrillation. The patient underwent successful thoracoscopic excision of the pericardial cyst under general anaesthesia. The patient's post-operative course was uneventful, and she was ultimately discharged in stable condition.DiscussionPericardial cysts are typically benign, but complications may arise in the case of compression of adjacent cardiac structures, inflammation, haemorrhage, or rupture of the cyst. Magnetic resonance imaging is considered the better modality for both diagnosis and follow-up of pericardial cysts. This case illustrates the need for long-term clinical follow-up in order to optimize the time for treatment.

Case Report: Congenital Intracranial Kaposiform Hemangioendothelioma Treated With Surgical Resection.

Project description:BackgroundKaposiform hemangioendothelioma (KHE) is a locally aggressive but non-metastatic vascular neoplasm. Most studies have been restricted to small case series of limited generalizability. Intracranial KHE is extremely rare with only three cases reported in the literature. Here, we report a case of congenital intracranial KHE who underwent surgical resection, and no lesion recurrence was seen during the follow-up period of 13 months.Case descriptionA 2-month-old boy initially presented with a left temporal mass following birth. Antenatal ultrasound at 36 weeks of gestation demonstrated a hyperechoic signal present in the left frontal lobe, with clear borders and irregular morphology. There were neither cutaneous abnormalities nor other neurologic examination abnormalities. No laboratory abnormality was identified. Computed tomography (CT) scans suggested that a massive hematoma was noted under the left frontal skull plate, with a little subdural hemorrhage in the adjacent temporal area. The adjacent meninges enhanced and thickened on contrasted T1 magnetic resonance (MR). After the multidisciplinary diagnostic assessment, the surgery was performed by the left frontotemporal craniotomy approach. The operation was extremely difficult. We completely removed the tumor, and the involved dura and brain tissue were resected with the lesion in a piecemeal fashion. On postoperative-day (POD) 3 and POD 14, the head CT re-examination revealed that cerebral perfusion improved gradually. The MRI of 6- and 12-month after operation showed no local recurrence or metastasis.ConclusionsIntracranial KHE is difficult to diagnose early and the prognosis has been uniformly poor. We supposed that meticulous intraoperative hemostasis is the key for a successful operation, and the radical resection of the tumor and involved structures are essential to reduce recurrence.

Laparoscopic resection of large oncocytoma with metaplastic ossification: Case report and video.

Project description:Renal oncocytoma (RO) represents about 7% of kidney tumors. They usually behave in a benign fashion, with a slow-growth rate. Patients are often asymptomatic and the tumour is found incidentally on imaging. Due to its wide variation of presentations and multiple radiological findings it is difficult to differentiate RO from renal-cell carcinomas. Interpretation of the images in the appropriate clinical context is crucial and supports the surgeon to avoid aggressive surgical procedures in favor of a nephron-sparing approach, whenever possible. We report a case of a 71-year-old female patient with a large calcified RO which was resected laparoscopically.

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

Project description:INTRODUCTION:Perineal 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 CASE:Here, 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. DISCUSSION:Recurrence 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. CONCLUSION:Symptomatic 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.

Complete resection for a giant recurrent biliary cystadenoma: A surgical case report and review of literature.

Project description:BackgroundBiliary cystadenoma is a rare cystic neoplasm of the liver. The clinical signs and symptoms are nonspecific, and treatment strategy is variable.Case presentationIn this study, we presented a case of a 32-year-old female with multilocular biliary cystadenoma. The patient underwent partial removal of the hepatic cyst two times in two different hospitals for two years and that the histopathological results were biliary cystic adenoma but was successfully treated by radical resection after the second recurrence. The patient underwent a J-shaped laparotomy. The giant cystic mass measuring 20 cm × 15 cm was below the position of the right anterior segment. This lesion pushed the liver parenchyma to both sides and compressed the hepatic hilum, causing dilatation of the intrahepatic bile ducts. The patient underwent complete resection of cystic mass. During the dissection, a 0.5mm-diameter fistula of left hepatic duct with the cyst was found. It was sutured using absorbable polydioxanone (PDS 6.0) and the cystic duct tube (C tube) (6 Fr) was inserted via the cystic duct into the left hepatic duct due to drain the bile fluid.DiscussionA biliary cystadenoma (BCA) primary origin is occasionally rare. Although imaging modalities such as ultrasound, computed tomography and magnetic resonance imaging could be suggestive, however, the definitive diagnosis is depended on the histological examination. Despite of being a benign tumor, it has a high risk of recurrence after conservative treatment. The potential risk for malignant is also present. Therefore, complete resection of the tumors is the treatment of choice.ConclusionWe herein present a report of a rare case with had a giant biliary cystadenoma (BCA) primary origin. This report aims to improve the understanding of the diagnosis and management of this uncommon disease.
