Abstract PDF

Temporary abdominal closure (TAC) is an abridged technique used after damage control surgery when primary closure is unattainable or can place patients at risk of complications such as intra-abdominal hypertension. Several techniques have been described for TAC. The ideal method should prevent bowel evisceration, prevent abdominal wall retraction or loss of domain, allow removal of infected fluids, and facilitate early definitive closure. Herein, we present a case where negative-pressure wound therapy was used for TAC. We describe the technique’s steps, aiming to simplify the procedure for experienced surgeons.

Abstract PDF

A patient with multiple comorbidities, including hypertension, type 2 diabetes, hyperlipidemia, and edema, and a prior history of abdominal surgery presented to the gastrointestinal department with a recurrent incisional hernia larger than 10 cm. The patient underwent laparoscopic extended totally extraperitoneal (e-TEP) hernia repair under general anesthesia. The bilateral retrorectal spaces were accessed via three trocars, followed by midline crossover in the upper abdomen and caudal dissection along the fascial defect. Due to the large size of the defect and the anticipated tension, posterior component separation (PCS) with transversus abdominis release (TAR) was performed, with careful preservation of the neurovascular bundles running anterior to the head of the transversus abdominis muscle. After separate closure of the posterior and anterior layers using barbed sutures, a mesh was placed in the intercomponent space to avoid direct contact with intraperitoneal structures. Closed-suction drains were placed bilaterally to prevent seroma formation. The procedure was completed successfully, and the patient experienced no complications. The patient was discharged without complications. A follow-up computed tomography scan demonstrated the integrity of the hernia repair, with progressive resolution of fat infiltration and fluid collection. Laparoscopic e-TEP hernia repair with PCS and TAR provides a safe and effective approach for managing complex recurrent incisional hernias. This technique enables tension-free closure with mesh placement while minimizing intra-abdominal complications.

Abstract PDF

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal (GI) tract. Although GISTs can occur anywhere along the GI tract, they are most frequently found in the stomach and small intestine. Duodenal GISTs are rare but clinically significant due to their symptomatology and potential for malignant transformation. Surgical resection remains the cornerstone of curative treatment. Laparoscopic surgery is now the main method for duodenal GIST due to its advantages, including a faster recovery, less pain, and shorter hospital stay. In this video, we demonstrate how we make different choices regarding the surgical methods for duodenal GIST during operation. The technical points are as follows: (1) preliminary judgment of the tumor location according to the preoperative computed tomography scan and gastroscopy findings, (2) fine dissection of the soft tissue and vessels around the duodenum, (3) intraoperative gastroscopy to confirm the tumor location, (4) the final decision regarding the surgical method according to the tumor location and size, (5) confirmation of luminal patency and hemostasis by intraoperative endoscopy.

Abstract PDF

D2 lymphadenectomy is the standard approach for lymph node dissection in curable gastric cancer. However, paraaortic lymph node (PALN) dissection in addition to D2 lymphadenectomy has not been shown to improve survival rates and is therefore not routinely performed. Nevertheless, PALN sampling may be indicated for diagnostic purposes because it can provide critical information for accurate staging and treatment planning. Laparoscopic PALN sampling, however, poses significant challenges due to limited accessibility and visibility in the paraaortic region. Moreover, the proximity of major blood vessels, such as the abdominal aorta and renal vein, is another difficult aspect of the procedure. In this context, we present two cases to demonstrate practical strategies for facilitating laparoscopic PALN sampling. The procedure can be effectively performed by first identifying the ligament of Treitz and then, when necessary, fixing the small bowel mesentery to the abdominal wall using a tagging suture so that there is adequate vision and enough working space. This enables careful and precise dissection of the target tissue without compromising the feasibility and safety of the operation.

Abstract PDF

Breast cancer is the most common cancer among women in Korea. Given the increased preference for breast-conserving surgery (BCS), preoperative localization is crucial, especially for non-palpable lesions, to ensure clear resection margins. Traditional methods such as wire-guided localization have limitations, including patient discomfort and wire migration. Recently, LuminoMark, an indocyanine green–macroaggregated albumin–hyaluronic acid mixture, has emerged as a promising alternative with potential benefits over existing techniques. We present a case of a 67-year-old female with a non-palpable Breast Imaging-Reporting and Data System 5 breast lesion. Preoperative localization was performed using LuminoMark, with accurate placement verified by a Lumino-imager. The lesion was successfully excised, and the absence of residual fluorescence confirmed complete resection. LuminoMark provided effective lesion localization without skin pigmentation, reducing the risk of misdiagnosis during follow-up. The procedure demonstrated a short learning curve, similar to that of charcoal localization. However, the need for a costly near-infrared fluorescence detector and the lack of long-term follow-up data are current limitations. Despite minor drawbacks, LuminoMark offers advantages over traditional localization methods, including improved aesthetics and reduced complications. This case demonstrates its feasibility as a next-generation localization technique for BCS, emphasizing the importance of an accurate injection technique to ensure adequate dispersion and complete tumor resection. Further studies are warranted to validate its long-term efficacy.

Abstract PDF

Feeding jejunostomy is crucial for patients with compromised oral intake, particularly after gastrointestinal surgery or esophagectomy. Traditional methods involve interrupted sutures to secure the feeding tube to the abdominal wall, but this can be cumbersome due to the need for knot tying. This paper presents the case of a 75-year-old male patient who underwent minimally invasive esophagectomy with feeding jejunostomy for esophageal cancer, and introduces the use of a knotless barbed suture, which is commonly employed in gastrointestinal operations. The laparoscopic procedure utilized four trocars for jejunostomy, employing a 3-0 silk purse string suture and a 14-Fr Foley catheter. The barbed suture was used to secure the catheter in place without knots, covering 360° around the catheter. This method aims to simplify laparoscopic feeding jejunostomy and improve clinical practice.

Abstract PDF

Since its introduction in the early 1990s, laparoscopic colorectal surgery has been extensively validated through randomized controlled trials, establishing its safety and efficacy from oncological and technical standpoints. Laparoscopic right hemicolectomy (LRHC) procedures exhibit variability in dissection extent and initiation sites. Complete mesocolic excision is essential in LRHC, involving precise dissection along embryologic planes and varying in lymph node dissection extent (D2 or D3). Other variations in LRHC include the use of the medial approach (or superior mesenteric vein [SMV]-first approach), where dissection starts along the SMV, the lateral approach (or inferior approach), starting with meso-ileal and retroperitoneal dissection, and the superior approach, initiated by separation of the omentum and transverse colon. This paper presents a case of LRHC for ascending colon cancer using an inferior approach. The procedure included trocar placement, followed by inferior, superior, and medial dissection phases, concluding with specimen extraction and extracorporeal anastomosis. With a standardized procedure, mastery of diverse approaches (inferior, medial, and superior) remains crucial, as the most appropriate method varies among cases.
