A 68-year-old female was operated for a giant dedifferentiated retroperitoneal liposarcoma (RLS) encasing entirely the right kidney. She had an en-bloc resection of the tumor with right nephrectomy. The en-bloc resection should avoid R1 resection margins. Renal conservation is suggested if the kidney is widely displaced and for elderly patient.

This study aimed to assess the utility of the S-O clip during colorectal endoscopic submucosal dissection (ESD). We conducted a retrospective study on 185 patients who underwent colorectal ESD from January 2015 to January 2020. The patients were divided into two groups: before and after the introduction of the S-O clip. Forty-two patients underwent conventional ESD (CO group) and 29 patients underwent ESD using the S-O clip (SO group). We compared the surgery duration, dissection speed, en bloc resection rate, and complication rate between both groups. Compared with the CO group, the SO group had a significantly shorter surgery duration (70.7 ± 37.9 min vs. 51.2 ± 18.6 min; p = 0.017), a significantly higher dissection speed (15.1 ± 9.0 min vs. 26.3 ± 13.8 min; p < 0.001), a significantly higher en bloc resection rate (80.9% vs. 98.8%; p ≤ 0.001), and a significantly lower perforation rate (4.3% vs. 1.3%). In the right colon, the surgery duration was significantly shorter and the dissection speed was significantly higher in the SO group than in the CO group. Moreover, the rate of en bloc resection improved significantly in the right colon. S-O clip-assisted ESD reduces the procedure time and improves the treatment effects, especially in the right colon.

AbstractLiposarcomas are neoplasms of mesodermal origin derived from adipose tissue representing 10 to 14% of all soft tissue sarcomas, with the most frequent subtype being liposarcoma. Given that the retroperitoneum is a large space in which the retroperitoneal liposarcoma can grow asymptomatically up until a mass effect develop. Hence, patients usually present late with symptoms with possible invasion to nearby structures. These tumors are known to reach significantly large dimension, despite their poor vascularization and can grow to enormous size, the average diameter of the tumor is 20 to 25 cm with a weight of 15 to 20 kg. Surgery with en-bloc resection of the tumor and adherent nearby structures, with intact capsule, remains the gold standard in surgical management of retroperitoneal sarcomas. Herein, we present a case of 52 year old male patient with a huge 48 cm right-sided retroperitoneal liposarcoma, managed surgically by en bloc excision of the tumor, right kidney, right ureter, right adrenal gland, and the right colon.

Duodenal Invasion

Direct invasion of colorectal adenocarcinoma into adjacent structures occurs frequently, but only rarely is the duodenum involved. This study was undertaken to assess the safety and efficacy of en bloc resection of locally advanced right colon carcinoma invading the duodenum. A retrospective review of 49 patients with locally advanced colon cancer, surgically managed between 2000 and 2005, was performed. Forty-six patients underwent en bloc resection of colon and adjacent organs not involving the duodenum. Three patients with duodenal invasion underwent en bloc partial duodenectomy. The mean operative blood loss, length of stay, postoperative morbidity, and mortality compare favorably between these two groups of patients. Of the 46 patients with en bloc resection of other organs, 27 are alive at 12 to 60 months follow up. Two patients with duodenal invasion are alive without recurrence at 15 and 20 months follow up. En bloc resection of colon cancer invading the duodenum can be performed safely because morbidity and mortality rates are comparable to those attending extended resections of other locally advanced colon carcinomas. Overall survival in patients who underwent surgery with curative intent justifies en bloc duodenal resection in selected patients.

Osteoclastoma (Giant Cell Tumor) of Cuboid bone is a rare bone tumor. GCT is primarily seen in metaphyseo-epiphyseal region of long bones after skeletal maturity. This patient is a 17 years old female, presented with painful swelling of the right foot. On conventional radiographs, there is osteolytic lesion in Cuboid bone of right foot. En bloc resection and autologous bone grafting (iliac crest) was done. Patient's pain and swelling disappeared following the procedure and there is no evidence of recurrence at 18 months follow up.

The aim of this study was to test whether a single testicular needle biopsy could provide histological results comparable to en bloc resection histology and whether one biopsy was sufficient to reflect the histology of an entire pair of testicles. Two methods of sample collection were tested on 32 bull calves aged five to eight months to compare histological parameters of needle biopsy with those of en bloc resection samples. One testicular needle biopsy of the right and three en bloc samples of both testicles were collected and compared for the number of tubular cross sections, tubules with elongated spermatids (ES), outer/inner diameter of tubules, thickness of tubular wall, and number of Sertoli cells (SC). Additionally, animal data were considered. No significant differences were found between the left and right testis or among the individual locations of en bloc samples. However, histologically significant differences (Bonferroni-adjusted significance level: p < 0.05/6 = 0.0083) were found between the needle biopsy and en bloc resection regarding the tubular cross sections per visual field (p < 0.05), the outer (p = 0.01) and inner diameter and the thickness of the tubular wall (both p < 0.01). In the SOX9 immunohistochemical staining, no significant differences (p > 0.05) could be observed for SC numbers between needle biopsy and en bloc samples. In conclusion, results of testicular needle biopsy do not have the same validity as the en bloc resection histology. Furthermore, one biopsy is insufficient to reflect the histology of the entire testicular pair.

Abstract Background The efficacy of the hanging maneuver for the retropancreatic nerve plexus (RNP) to enhance the confirmation of the margin status and to facilitate en-bloc resection for pancreatoduodenectomy (PD). In this report, we present the knack and pitfall of the hanging maneuver of the RNP. MethodsThe exit of the hanging maneuver of the RNP is the left part of the superior mesenteric artery (SMA), and the entry is the cranial part of the celiac axis. The entry of the hanging maneuver was connected to the dissection line on the right side of the celiac axis. Thereafter, the tape of the hanging maneuver was pulled to the right side, and the RNP was deployed widely. Finally, the RNP was easily dissected using a sealing device other than IPDA ResultsIt is important to clarify the entrance and exit of the hanging taping in this procedure. This permitted the wide spaces between the SMA, SMV, and the resected side, and it was easier to identify the IPDA. By traction of the hanging maneuver tape, a clear line may be drawn between the resection side and the remaining side. ConclusionsWith the correct implementation of the hanging maneuver, we believe that it would be possible to obtain reliable R0 resection as well as a reduction in blood loss and operation time.
