AI Article Synopsis
- The study presents a novel laparoscopic approach for segment 7 (S7) liver resections that avoids traditional methods' complications by utilizing an in situ split technique, which streamlines the process and adheres to "no-touch" principles for tumors.
- From September 2017 to May 2019, 24 patients underwent this procedure with successful outcomes, showing that it is technically feasible and effective in achieving R0 resections of primary liver cancer.
- The results indicated good operational success, including no perioperative deaths, average surgery time of about 216.5 minutes, and manageable blood loss, demonstrating that this approach provides better visibility and maneuverability.
Article Abstract
Background: The traditional open or laparoscopic segmentectomy of liver segment 7 (S7) requires exposing and controlling the root of the right hepatic vein(RHV)after full mobilization and lifting up of the right liver before liver transection. This approach violates the "no-touch" principle for malignant tumors, and makes laparoscopic resection technically challenging. So reports on isolated totally laparoscopic anatomic S7 segmentectomy have rarely been reported. This study describes our experience in laparoscopic anatomic S7 segmentectomy using in situ split along the right intersectoral and intersegmental planes of the liver. To our knowledge, this is the first description of this novel approach.
Methods: From September 2017 to May 2019, patients who underwent laparoscopic anatomic S7 segmentectomy for hepatocellular carcinoma at the HPB Surgery Department, Sun Yat-Sen Memorial Hospital entered into this retrospective study. This in situ split approach was designed using main vessels as the plane markers of right intersectoral and intersegmental planes, along which liver transection was carried out. There was no need to mobilize the right liver and control the root of RHV.
Results: There were 9 women and 15 men. The average diameter of the tumors on preoperative CT/MR was 3.4 cm (range 2-6 cm). All the procedures were successfully carried out laparoscopically. There was no perioperative death. The average operative time was 216.5 min (range 180-310 min). The average blood loss was 320 ml (range 120-620 ml). Pathological study showed all the operations to be R0 resections.
Conclusion: Laparoscopic anatomic S7 segmentectomy using the in situ split approach resulted in R0 liver resection in all our patients with primary liver cancer. The operation was technically feasible and it provided a better view and increased maneuverability in the cramped operative space compared with the traditional open/laparoscopic approach. The approach also better complies with the "no-touch" principle for malignant tumors. Its long-term oncological outcomes require further studies.

Introduction: This study examined factors that affected sentinel lymph node (SLN) identification of patients with endometrial cancer having a preoperative estimation of low recurrent risk.
Methods: This study included 97 patients with endometrial cancer who attempted to identify SLN using a uterine cervical injection of technetium-99 m phytate under laparoscopic or robotic-assisted surgery at our institute. A preoperative single photon emission computed tomography (SPECT) and intraoperative gamma probe were used to detect hot nodes.

Spigelian hernia and cryptorchidism syndrome in children is increasingly reported in the literature. A variety of phenotypes have been reported, so diagnostic approaches and operative techniques remain poorly defined. The case of an infant male who presented with a left spigelian hernia and ipsilateral cryptorchidism who was initially misdiagnosed with an ectopic inguinal testis is presented.

Introduction: The coexistence of gallbladder (LSG) and adenomyomatosis (ADM) is extremely uncommon presenting a novel clinical dilemma that has not been previously documented. LSG refers to a anomaly where the gallbladder is situated to the left of the round ligament deviating from its usual position. This anomaly is rare, with reported occurrences ranging between 0.

Introduction: The cyst of the canal of Nuck is a rare cause of inguino-labial swelling in adult women, arising from an obliteration failure of the processus vaginalis during embryological development. Its rarity often leads to misdiagnosis and improper treatment. This article highlights its diagnosis and surgical management.

Background: Fluorescence-guided lymphadenectomy (FLND) using indocyanine green (ICG) has emerged as a promising technique to enhance the accuracy of lymphadenectomy in rectal cancer surgery. Effective lymphadenectomy is crucial for improving prognosis in patients with advanced rectal cancer, but it remains technically challenging and controversial.
Methods: This prospective nonrandomized controlled study was conducted involving 129 patients underwent laparoscopic surgery, and 64 patients assisted by FLND.
