ABSTRACT

Purpose@#This study aimed to compare the intraoperative and postoperative outcomes between robotic and laparoscopic transperitoneal adrenalectomies. @*Methods@#In this retrospective study, 93 patients underwent adrenalectomy using 2 surgical modalities: 45 patients underwent adrenalectomy using the da Vinci Xi system (robotic group), and 48 patients using laparoscopic devices (laparoscopic group). We compared the operation time, intraoperative bleeding, and hospital stay according to the surgical modality and tumor characteristics. @*Results@#There were no significant differences in the operative time (P = 0.827), hospital stay (P = 0.177), and intraoperative bleeding (P = 0.174) between the groups. However, the robotic group showed a lower coefficient of variation in total operative time than that of the laparoscopic group (100.6 ± 23.3 minutes vs. 101.9±32.7 minutes, 0.230 vs. 0.321). When divided into 2 subgroups based on the tumor size (3 cm had a shorter operative time than that of the laparoscopic group (P = 0.032). The robotic group also had fewer cases of intraoperative bleeding (P = 0.034). @*Conclusions@#Compared to the laparoscopic transperitoneal adrenalectomy, the robotic one achieved a lower deviation in total operative time and showed less bleeding and a shorter operative time, especially for tumors sized >3 cm.

ABSTRACT

Purpose@#Endoscopic breast surgery for patients with breast cancer was introduced for its superior cosmetic outcomes; it was initially studied in the field of breast-conserving surgery and, more recently, in robotic-assisted nipple-sparing mastectomy (NSM). The main purpose of this study was to investigate the feasibility and safety of endoscopic NSM (E-NSM) in patients with breast cancer by comparing E-NSM and conventional NSM (C-NSM). @*Methods@#Between May 2017 and October 2020, we retrieved the records of 45 patients who underwent NSM with permanent silicone implants and divided them into the E-NSM group (20 patients) and the C-NSM group (25 patients), depending on the use of the endoscopic device.We also analyzed demographic information, pathology, operative time, and complications. @*Results@#No significant differences were observed between the 2 groups based on demographic information, postoperative pathological data, mean length of hospital stay, and total number of complications. The mean preparation time for surgery was comparable between both groups. Compared to the C-NSM group, the E-NSM group had a significantly longer mean operative time and, subsequently, a significantly longer mean total operative time and number of complications. @*Conclusion@#The results showed that E-NSM was feasible and safe with a more inconspicuous incision in patients with breast cancer.

ABSTRACT

PURPOSE: Noninvasive precursor lesions for pancreatic adenocarcinoma include pancreatic intraepithelial neoplasia (PanIN), intraductal papillary mucinous neoplasm, and mucinous cystic neoplasm. PanIN is often found synchronously adjacent to resected pancreatic ductal adenocarcinoma (PDAC) tumors. However, its prognostic significance on outcome after PDAC resection is unknown. The purpose of the current study was to determine if the presence of PanIN has a prognostic or predictive effect on survival after resection for PDAC with curative intent. METHODS: We retrospectively reviewed the clinicopathologic data of patients who underwent pancreatectomy for PDAC from January 2002 to January 2013. Intraductal papillary mucinous lesions and mucinous cystic neoplasms were excluded. All available postoperative imaging and clinical follow-up data were reviewed. RESULTS: There were 95 patients who underwent pancreatectomy. Tumors were most commonly located in the pancreas head and as such pancreaticoduodenectomy was the most commonly performed operation. The median tumor size was 3.2 cm. An absence of PanIN lesions was identified in 39 patients (41%). Of the patients with PanIN lesions, high-grade PanIN (grade 3) was the most common type (64.3%) followed by grade 2 (28.6%). There was no significant difference in overall survival or disease-free survival between the non-PanIN and PanIN groups. CONCLUSION: The presence or absence of PanIN lesions did not affect survival in patients undergoing resection for pancreatic cancer. However, patients with high-grade PanINs tended to have better overall survival. Larger studies with longer follow up are needed to accurately determine its clinical significance.

ABSTRACT

Paraduodenal hernia is by far the most common form of congenital internal hernia. Chylous ascites is an accumulation of lymphatic fluid in the peritoneal cavity. It develops when the lymphatic system is disrupted due to traumatic injury or obstruction. A 40-year-old, woman showed up to the Emergency Department with severe, colicky abdominal pain. Tenderness and rebound tenderness were observed at the left abdomen. Abdominal CT confirmed a cluster of dilated proximal small bowel loops with ischemic change, without ascites. The patient underwent an emergency surgery to relieve bowel ischemia. As soon as the peritoneum was exposed, 1.5 L of chylous fluid was found. A hernial sac was found along the posterior side of the mesentery of the inferior mesenteric artery. We resected the hernial sac and pulled out the herniated small bowel. On the sixth day after the surgery, she was discharged without any complication.
