Indocyanine green fluorescence imaging (ICG-FI)-a sensitive tool for detecting tumor localization in laparoscopic surgery-produces false positive results for benign liver tumors. This report is the first case of hepatic angiomyolipoma (HAML) treated laparoscopically with ICG-FI. We present the case of a 31-year-old woman with a liver tumor that was a 13-mm mass in the anterior superior segment. Though a benign tumor was suspected, malignant potential could not be ruled out. Therefore, minimally invasive laparoscopic resection using ICG-FI was planned. ICG, intravenously injected preoperatively, revealed the tumor's existence. Pure laparoscopic hepatectomy with ICG-FI was performed for excisional biopsy, during which the tumor was resected with adequate surgical margins, followed by histological confirmation of HAML. In conclusion, it is suggested that laparoscopic resection with ICG-FI is an effective minimal invasive surgery for tumors that are difficult to detect, such as HAML, leading to a safe surgical margin.

Although gastrointestinal stromal tumor (GIST) can present with various histological characteristics, GIST mimicking perineurioma has not been previously reported. We present the case of a 47-year-old woman diagnosed with GIST after laparoscopic resection of a stomach tumor near the lesser curvature of the gastric body close to the cardia. Morphological features resembled a perineurioma.

Adult intussusception is an uncommon condition that constitutes a small percentage of cases of bowel obstruction in adults. Unlike its paediatric counterpart, it is often linked to an underlying pathology, necessitating surgical interventions for diagnosis and treatment. This report discusses a case involving a 54-year-old woman who presented with symptoms of small bowel obstruction, including abdominal pain, nausea, and constipation, along with a one-month history of weight loss.

Background: Neoadjuvant chemoradiotherapy for rectal cancer improves surgical outcomes and reduces recurrence but can cause low anterior resection syndrome (LARS), affecting quality of life. This study aims to predict the risk of LARS in male patients with mid-low rectal cancer after laparoscopic total mesorectal excision (TME).
Methods: Clinical data from 203 male patients with mid-low rectal cancer who underwent neoadjuvant therapy and laparoscopic resection were collected.

Background: Endoscopic resection of giant gastric leiomyomas, particularly in the fundus and cardia regions, is infrequently documented and presents a significant challenge for endoscopic surgery.
Case Summary: Herein, a case of a 59-year-old woman with a giant gastric leiomyoma was reported. The patient presented to the department of hepatological surgery with a complaint of right upper abdominal pain for one month and worsening for one week.

The surgical management of hepatic metastases from colorectal cancer may range from segmental resections to major or extended hepatectomies. The aim is to achieve complete removal of metastatic lesions while preserving adequate liver function. We present the case of a 42-year-old male patient with a history of glucose intolerance who presented with altered bowel movements and abdominal pain.
