Laparoscopic Deroofing and Excision of a Large Left Renal Cyst Mimicking Chest Infection: Case Report

Background: The routine use of abdominal ultrasonography and computed tomography scan has increased the detection of asymptomatic renal cysts. Laparoscopy is usually suitable for treating large symptomatic renal cysts. Objective: To report a case of laparoscopic treatment of a man with large left renal cyst mimicking chest infection. Case presentation: A 75-year-old man, known hypertensive who had empirical treatment for chest infection without resolution of symptoms of cough and chest pain. He was on treatment for storage and voiding lower urinary tract symptoms with 10mg alfuzocin. Abdominal ultrasound and computed tomography scan confirmed a large left renal cortical cyst that measured 380mls. He subsequently had transperitoneal laparoscopic deroofing and excision of the renal cyst with operation finding of 300mls of straw coloured fluid excluding spillage. The immediate postoperative period was uneventful, and he was discharged home in a stable condition on the second day. The aspirate yielded no growth while the cytology report of cystic fluid was acute-on-chronic inflammation. Histology was reported as chronic pyelonephritis with cystic degeneration. Conclusion: Large renal cyst should be considered as differential diagnosis of unresolved chest infection and is safely treated by laparoscopic deroofing and excision.

Biliary cystadenoma a case report

Biliary cystadenoma (BCA) is a rare cystic neoplasm of liver with malignant potential and female predominance, mostly asymptomatic that will lead to late identification. BCAs are mostly do not communicate with Biliary tract but communication was reported in some studies, BCA has higher rate of recurrence after incomplete removal so the standard management is complete resection or partial hepatectomy. We report a case of BCA in 72-year aged female with ECOG score 3. Computed tomography showed BCA involving segment II, III, IV and VIII of liver without any malignant features, which was treated with laparoscopic deroofing with omentopexy and no recurrence at 1 year follow up. We used indocyanine green-fluorescent image to look for biliary communication. This study aims to report that minimal accesses surgery with deroofing and omentopexy can be alternative treatment for BCA without any malignant features in a poor performance status and use of Indocyanine green-fluorescent image to avoid biliary injury and rule out communication.

Comparison of aspiration with sclerotherapy and laparoscopic deroofing for the treatment of symptomatic simple renal cysts: a systematic review and meta-analysis

There are currently several strategies for the treatment of symptomatic simple renal cysts, such as aspiration with sclerosants and laparoscopic deroofing. However, no clear indication exists for choosing between them. Here, we carried out a systematic review and a meta-analysis of studies, which compared symptomatic and radiological success between aspiration with sclerotherapy and laparoscopic deroofing. Results were reported as relative risk (RR) and 95% confidence interval (95% CI) using laparoscopic deroofing as control group. The symptomatic and radiological successes were evaluated by 6 and 3 studies, respectively. Notably, aspiration with sclerotherapy was associated with higher risk of failure than laparoscopic deroofing (RR = 2.82; 95% CI = 1.84–4.31 for symptomatic failure; RR = 8.31; 95% CI = 4.22–16.38 for radiological failure). On the other hand, however, aspiration with sclerotherapy was associated with less frequent complications, shorter treatment duration and post-treatment hospital stay, and lower costs. Thus, our work underlines benefits and drawbacks of each intervention, raising the need for further studies to design guidelines for the management of simple renal cysts.

Development of Glycerol-Rose Bengal-Polidocanol (GRP) foam for enhanced sclerosis of a cyst for cystic diseases

Polycystic kidney disease (PKD) is a common genetic disorder that results in a proliferating and enlarging cyst and ultimately leads to loss of kidney function. Because an enlarged cyst is a primary factor for limited kidney function, the large cyst is surgically removed by laparoscopic deroofing or sclerosant. This a relatively nascent treatment method entails complications and sometimes fail due to the cyst fluid refilling and infection. This study proposes using a more stable and effective polidocanol foam with glycerol and Rose Bengal (GRP form) to prevent cyst regeneration and irritation, which is caused by the required body movement during the treatment. Specifically, the foam retention time and viscosity were increased by adding glycerol up to 10% (w/v). The GRP form inhibited cellular proliferation and disrupted cellular junctions, e-cadherin, and cyst formation, demonstrated by the LDH, Live and Dead, and re-plating culture assays. The GRP foam was shown to be a safe and effective treatment as a commercial grade polidocanol foam form by an in vivo study in which subcutaneously injected mice injected with commercial 3% polidocanol, and the GRP foam showed no difference in inflammation. Thus, this study provides an advanced polidocanol form by adding glycerol and Rose-Bengal to help existing sclerotherapy.

Single-Incision Laparoscopic Deroofing and Omentalization of a Cystic Renal Adenoma in a Dog

ABSTRACT A 12 yr old 13.5 kg male castrated Pembroke Welsh corgi was presented for evaluation of a suspected renal cyst following multiple episodes of lethargy and abdominal pain. Abdominal imaging revealed a large, thin-walled, hypoechoic cystic lesion associated with the cranial pole of the left kidney and a second smaller cystic lesion on the caudal pole. The larger cystic lesion was repeatedly drained percutaneously, but the lesion returned to initial size and clinical signs returned within weeks. Percutaneous ethanol sclerotherapy achieved only transient improvement in lesion size and abdominal discomfort. Laparoscopic deroofing and omentalization of the larger left renal cystic lesion was performed. The resected cystic wall was histopathologically consistent with a renal adenoma. Abdominal ultrasonography performed 1 mo postoperatively found no recurrence of the cystic renal adenoma. Repeated ultrasonography at 3 mo postoperatively detected a small cystic lesion at the cranial pole of the left kidney, which remained static in appearance at 11 and 18 mo postoperatively. During all follow-up visits, the dog was reported to be doing well with no recurrence of clinical signs. Renal cysts causing clinical signs and renal adenomas are rare in veterinary medicine; laparoscopic deroofing and omentalization provides a minimally invasive treatment approach.
