The purpose of the present paper is to describe our technique and experience with retroperitoneal hand-assisted laparoscopic (HAL) nephrectomies as an alternative to the transperitoneal approach. Eight retroperitoneal HAL nephrectomies and one partial nephrectomy were performed. Several excisional techniques were employed incorporating the Harmonic scalpel or Ligasure device. Hemostatic agents were used to cover the renal defect. Surgical bolsters were sutured to the renal capsule with pleget reinforcements to aid in hemostasis. The average operative time was 210 min and estimated blood loss 110 mL. Mean change in hematocrit was 3 units and creatinine was 1 point. No patient required a transfusion. There were no major complications, with a mean follow-up of fourteen months. On average, patients resumed oral intake in 2 days, and were discharged in 3 days. Pathological examination revealed that two lesions were benign and seven malignant. Tumor diameter averaged 3 cm. There were no positive surgical margins. In conclusion, we have demonstrated the feasibility of retroperitoneal laparoscopic hand-assisted nephrectomy and partial nephrectomy surgery for solid renal masses.

Objectives: To evaluate oncological feasibility and oncological and functional results of retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy (LPN). Patients and methods: Patients with posterior renal masses with low nephrometry score (RENAL ≤ 7) treated who underwent retroperitoneal sutureless zero ischemia.in a single center from January 2016 to November 2017. Clinical, surgical and pathological data were prospectively collected. Complications were reported according to the modified Clavien classification. Results: Retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy was performed on 15 patients. The indication for nephron-sparing surgery was elective in 11 (73%) patients and imperative in 4 (27%). Median RENAL score was 5 (IQR: 5-7), median tumor diameter 25 mm (IQR: 20-35). In 11 cases, the tumor was located polar (85%), and in 2 cases hilar (15%). There were no intraoperative complications. No cases were converted to radical nephrectomy, and in no case parenchyma suture was necessary. Median operative time was 90 min (IQR:40-150), in no case clamping of the renal artery was necessary, median hospital stay was 4 days, median estimated blood loss (EBL) was 310 (180-500) ml. Pathological analysis showed renal cell carcinoma in 11 patients (85%), 9 (60%) staged T1a and 2 (13%) T1b. In 4 (27%) an oncocytoma was found. There were no positive surgical margins. One patient developed a major postoperative complication (postoperative renal bleeding requiring super-selective embolization). Trifecta rate was 93%. Conclusions: Sutureless retroperitoneal zero ischemia LPN for the treatment of low-complexity posterior renal masses showed to be safe and feasible. Longer follow-up and higher numbers of patients are, however, warranted to draw definitive conclusions on functional outcomes.

Objective: The aim of this study is to assess the safety and feasibility of the transperitoneal laparoscopic approach during nephron sparing surgery in patients with previous abdominal surgery. Patients and methods: We retrospectively analyzed patients undergoing transperitoneal laparoscopic partial nephrectomy for renal masses. All patients had received a diagnosis of cT1a renal exophytic mass (⩽5 cm). Patients were divided into two groups, those with and without previous abdominal surgery. Patients with solitary kidney or major previous abdominal surgery were excluded in this study. The operative time, estimated blood loss, length of stay, surgical complications, and positive surgical margins were recorded to compare outcomes among two groups. Results: Of the 157 patients who were included in our study, 71 (45.3%) had a history of abdominal surgery (Group 1), while the remaining 86 (54.7%) had not (Group 2). Cholecystectomy was the most common previous surgery performed near the renal fossa. Patients with previous abdominal surgery experienced increased operative time (111.5 vs 83.2 min; p = 0.001). However, no statistically significant difference was found in estimated blood loss (122.1 vs 114.4 mL; p = 0.363), length of stay (4.1 vs 3.8 days; p = 0.465), rate of conversion to open surgery (2.8% vs 2.3%; p = 0.234), and rate of complications ( p = 0.121). However, operative time ( p = 0.003) and length of stay ( p < 0.001) were greater in patients with versus those without previous open cholecystectomy. Conclusion: Our results suggest that laparoscopic partial nephrectomy after minor previous abdominal surgery is safe and feasible in selected patients affected by renal masses with low nephrometry score. However, previous cholecystectomy results in an increased risk of conversion to open surgery and longer hospital stay in patients undergoing right laparoscopic partial nephrectomy.

Abstract Purpose: To compare the trifecta outcome and perioperative and postoperative outcomes among open partial nephrectomy (OPN), laparoscopic partial nephrectomy (LPN), and robotic-assisted partial nephrectomy (RAPN) in patients with small renal masses in Ramathibodi Hospital.Methods: We retrospectively reviewed 141 patients who underwent partial nephrectomy from January 2009 to December 2018. The baseline characteristics and preoperative outcomes were compared among the three surgical approaches. Results: Among the 141 patients, 42 (29.79%), 29 (20.57%), and 70 (49.64%) patients underwent OPN, LPN, and RAPN, respectively. Among 116 patients with available data, 71 achieved the trifecta outcome [18 (56.25%), 14 (56.00%), and 39 (73.58%) in the OPN, LPN, and RAPN group, respectively; p=0.276]. The rate of conversion to OPN was higher in the LPN than RAPN group. The number of patients who received intraoperative packed red cells was lowest in the RAPN group. The estimated blood loss was significantly lower in the LPN group than OPN and RAPN groups (p=0.041). The operative time was shorter in the OPN group than LPN and RAPN groups (p<0.001). Multivariate analysis showed that the intraoperative complication rate was a predictive factor for trifecta outcome achievement.Conclusion: OPN had the shortest operative time. LPN had the highest rate of conversion to OPN and lowest estimated blood loss. The number of patients who received intraoperative packed red cells was lowest in the RAPN group. However, achievement of the trifecta outcome was not significantly different among the three groups. The predictive factor for trifecta outcome achievement was the intraoperative complication rate.

Objective To retrospectively review our experience with the diagnosis and treatment of carotid bifurcation tumors (CBFT). Methods This was a retrospective study of 60 patients with CBFT who underwent surgical and conservative treatment. The patients’ clinicopathological features, imaging examination findings, treatment strategy, and prognosis were analyzed. The surgical grade, blood loss, tumor size, operative time, and postoperative complications were analyzed by Spearman’s correlation. Results Resection was performed in 52 patients with 53 tumors. The mean tumor volume, operative time, estimated blood loss, and follow-up time was 47.62 ± 65.28 cm3, 176.1 ± 86.55 minutes, 231.3 ± 354.0 mL, and 44.42 ± 29.30 months, respectively. Pathological examination showed that the number of carotid body tumors (CBT; paraganglioma), neurilemmoma, mesenchymal tissue tumor, and angioleiomyoma was 42, 8, 1, and 1, respectively. Of the CBT group, the rate of Shamblin Type I, II, and III was 11.9%, 59.5%, and 28.6%, and three cases were malignant CBT with lymph node metastasis. Spearman’s correlation analysis showed that complication grade was significantly related to surgical difficulty grade and operative time. Conclusion CBT is the most frequent lesion in CBFT, and CBT may be treated safely by surgical management. The severity of surgical complications is significantly correlated with surgical difficulty.

Abstract Objectives Juvenile nasopharyngeal angiofibromas (JNAs) are uncommon tumors with an evolving treatment paradigm. The objective of this study was to compare our prior experience reported in 2005 with our most contemporary series to compare practice improvements and the impact of expanded endonasal procedures. Design Retrospective review comparing a contemporary 22 patients with JNA who underwent surgical management between 2005 and 2019, compared with a historical cohort of 65 patients from the same center. Results The most common presenting symptom was epistaxis (68%). The median maximum tumor diameter was 4.4 cm. All patients underwent preoperative embolization. An endoscopic endonasal approach (EEA) was used in 18 patients (82%), compared with 9% in the series prior to 2005. Gross total resection was achieved in all patients. The median estimated blood loss was 175 and 350 mL for EEA and open (transfacial) cases, respectively. Only two patients (9%) required a blood transfusion compared with 52% on the previous series. The median follow-up was 19 months. The overall recurrence rate was 9% in this series and 24% in the previous series. No patient required radiation therapy in follow-up compared with 3% in our historical cohort. Conclusion There have been significant changes regarding the management of patients with JNA compared with the previous Mayo Clinic experience. The EEA has become the preferred route over the transfacial approaches to treat JNA in selected patients who do not have intracranial extension. Preoperative embolization has aided in reducing the postoperative transfusion rates.

Abstract Purpose Many transanal endoscopic surgeries require a high level of technical expertise and surgeon experience. Considering the economic feasibility of material acquisition and the technical feasibility of training and experience with complex methods, a simpler technique with available resources is relevant for the excision of rectal adenomas. This study presents the surgical and postoperative results achieved with a novel proctoscope using the transanal endoscopic technique to excise rectal adenomas. The results are compared to the results obtained with other currently employed transanal techniques. Methods We retrospectively investigated the medical records of patients who underwent transanal endoscopic operations from April 2000 to June 2018 at two tertiary referral centers for colorectal cancer. Results This study included 99 patients. The mean age was 65.3 ± 13.3 years. The average size of the adenomas was 4.6 ± 2.3 cm, and their average distance to the anal border was 5.6 ± 3.3 cm. The average operative time was 65.3 ± 41.7 min. In 48.5% of the operations, the specimen was fragmented, and in 59.6% of the cases, the microscopic margins were free. The rates of postoperative complications and relapse were 5% and 19%, respectively. The mean follow-up was 80 ± 61.5 months. Conclusions The described proctoscope proved to be a viable technique with results similar to other techniques, with the advantage that it allowed greater accessibility for surgeons. Therefore, its use could be implemented and become widespread in surgical practice.

This study describes the surgical technique and intra- and postoperative complications associated with the use of a radiofrequency bipolar coagulator in a series of 18 Piver type III-IV radical hysterectomies performed in cervical cancer patients. Preliminary vessel-by-vessel dissection of the lateral parametria was possible in 17 out of 18 (94%) cases, and a direct application of a radiofrequency bipolar coagulation instrument was performed to coagulate the posterior and anterior parametrial tissues in all cases. We were able to easily coagulate isolated vessels up to 5 mm of maximal diameter. In no case were clamps or hemoclips necessary to complete hemostasis. We did not observe any parametrial vessel damage or heat-related injury of the surrounding normal tissue. The median size of the parametria removed was 44 mm (range 31–58) and nodes were detected in 15 cases (83%). Median operative time and estimated blood loss for the whole procedure including systematic pelvic and aortic lymphadenectomy was 250 min (range 200–410) and 550 ml (range 400–2500), respectively. Median follow-up time was 9 months (range 5–13). No complications specifically related to the use of radiofrequency coagulation were found. In conclusion the radio-frequency coagulation with this instrument appears to be a safe technique that is particularly useful in reducing blood loss and operative time without affecting radicality in patients undergoing radical hysterectomy.

<p><strong>Introduction: </strong>We sought to evaluate the association of obesity with surgical outcomes of robotic partial nephrectomy (RPN) using a large, multicentre database.<strong> </strong></p><p><strong>Methods: </strong>We identified 1836 patients who underwent RPN from five academic centres from 2006-2014.  A total of 806 patients were obese (body mass index [BMI] ≥30 kg/m<sup>2</sup>). Patient characteristics and outcomes were compared between obese and non-obese patients. Multivariable analysis was used to assess the association of obesity on RPN outcomes.</p><p><strong>Results: </strong>A total of 806 (44%) patients were obese with median BMI of 33.8kg/m<sup>2</sup>. Compared to non-obese patients, obese patients had greater median tumour size (2.9 vs. 2.5 cm, p&lt;0.001), mean RENAL nephrometry score (7.3 vs. 7.1, p = 0.04), median operating time (176 vs. 165 min, p=0.002), and median estimated blood loss (EBL, 150 vs. 100 ml, p=0.002), but no difference in complications. Obesity was not an independent predictor of operative time or EBL on regression analysis. Among obese patients, males had a greater EBL (150 vs. 100 ml, p&lt;0.001), operative time (180 vs. 166 min, p&lt;0.001) and warm ischemia time (WIT, 20 vs. 18, p=0.001) and male sex was an independent predictor of these outcomes on regression analysis.</p><p><strong>Conclusion: </strong>In this large, multicentre study on RPN, obesity was not associated with increased complications and was not an independent predictor of operating time or blood loss.  However, in obese patients, male gender was an independent predictor of greater EBL, operative time, and WIT.  Our results indicate that obesity alone should not preclude consideration for RPN.<strong></strong></p>
