목적: 유문부보존 위절제술(pylorus-preserving gastrectomy, PPG)은 유문륜을 보존하여 잔위의 배출기능을 보존하고 담즙 역류를 방지할 수 있는 기능 보존 수술법으로 조기위암 치료에 적용되고 있다. 저자들은 복강경 보조 유문부보존 위절제술(laparoscopy-assisted pylorus-preserving gastrectomy, LAPPG)의 초기 경험을 LADG 후 Billroth-I 재건술과 비교 분석하였다. 대상 및 방법: 2006년 11월부터 2007년 9월까지 원자력병원 외과에서 복강경 보조 위절제술을 시행 받은 39명의 조기위암 환자 중 LAPPG (n=9)와 LADG 후 Billroth-I 재건술(n=18)을 시행 받은 27명의 환자를 대상으로 하였고, 양 군간의 임상병리학적 변수를 비교하였다. 저자들은 LAPPG 시행 중 유문하동맥, 우위동맥, 미주신경 간지, 유문지 및 복강지를 보존하였으며, 림프절 절제술은 우위동맥 림프절(No. 5)을 제외한 D1+$\beta$술식을 시행하였고, 유문륜 상방 $3{\sim}4\;cm$에서 원위부 위절제를 시행하였다. 결과: LAPPG을 시행 받은 환자 9명의 평균 연령은 $59.9{\pm}9.4$세였으며 남녀 성비는 1.3 : 1.0 (남자 5명, 여자 4명)이었고, LADG 후 Billroth-I 재건술을 시행 받은 환자 18명의 평균 연령은 $64.1{\pm}10.0$세였으며 남녀 성비는 2.6 : 1.0 (남자 13명, 여자 5명)이었다. LAPPG 군과 LADG 후 Biliroth-I 재건술을 시행받은 군에서 절제된 림프절의 개수는 각각 $28.3{\pm}11.9$개 $28.1{\pm}8.9$개, 수술 시간은 각각 $269.0{\pm}34.4$분, $236.3{\pm}39.6$분, 술 중 출혈량은 각각 $191.1{\pm}85.7\;ml$, $218.3{\pm}156.6\;ml$, 술 후 첫 가스 배출은 각각 $3.6{\pm}0.9$일, $3.5{\pm}0.8$일에 있었고 술 후 첫 유동식은 각각 $5.1{\pm}0.9$일, $5.1{\pm}1.7$일에 섭취하였고 술 후 재원 기간은 각각 $10.1{\pm}4.0$일, $9.2{\pm}3.0$일로 모두 통계학적으로 유의한 차이가 없었다(P>0.05). 술 후 합병증은 LAPPG 군에서 위저류증 1예와 창상 장액종 1예가 발생하였고, LADG 후 Biliroth-I 재건술을 시행 받은 군에서는 좌외측간엽경색 1예가 발생하였다. 결론: 조기위암의 치료에 있어서 LAPPG는 기능 보존 수술 법으로 적용 가능하며, 적절한 적응증을 사용하면 임상종양학적 측면에서도 LADG 후 Billroth-I 재건술과 동등한 결과를 보일 것으로 기대된다.

Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3.0 cm currently, its optimal length still remains unclear. Standard procedures for the preservation of pyloric function, infra-pyloric vessels, and hepatic branch of the vagus nerve, make PPG technically more difficult and raise concerns about incomplete lymph node dissection. The short- and long-term oncological and survival outcomes of PPG were comparable to those for distal gastrectomy, but with several advantages such as a lower incidence of dumping syndrome, bile reflux, and gallstone formation, and improved nutritional status. Gastric stasis, a typical complication of PPG, can be effectively treated by balloon dilatation and stent insertion. Robot-assisted pylorus-preserving gastrectomy is feasible for EGC in the middle-third of the stomach in terms of the short-term clinical outcome. However, any benefits over laparoscopy-assisted PPG (LAPPG) from the patient's perspective have not yet been proven. An ongoing Korean multicenter randomized controlled trial (KLASS-04), which compares LAPPG and laparoscopy-assisted distal gastrectomy for EGC in the middle-third of the stomach, may provide more clear evidence about the advantages and oncologic safety of PPG.

Purpose: This study aimed to compare the surgical and oncological outcomes between totally laparoscopic pylorus-preserving gastrectomy (TLPPG) with intracorporeal anastomosis and laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with extracorporeal anastomosis. Materials and Methods: A retrospective analysis was performed in 258 patients with cT1N0 gastric cancer who underwent laparoscopic pylorus-preserving gastrectomy using two different anastomosis methods: TLPPG with intracorporeal anastomosis (n=88) and LAPPG with extracorporeal anastomosis (n=170). The following variables were compared between the two groups to assess the postoperative surgical and oncological outcomes: proximal and distal margins, number of resected lymph nodes (LNs) in total and in LN station 6, operation time, postoperative hospital stay, and postoperative morbidity including delayed gastric emptying (DGE). Results: The average length of the proximal margin was similar between the TLPPG and LAPPG groups (2.35 vs. 2.73 cm, P=0.070). Although the distal margin was significantly shorter in the TLPPG group than in the LAPPG group (3.15 vs. 4.08 cm, P=0.001), no proximal or distal resection margin-positive cases were reported in either group. The average number of resected LN was similar in both groups (36.0 vs. 33.98, P=0.229; LN station 6, 5.72 vs. 5.33, P=0.399). The operation time was shorter in the TLPPG group than in the LAPPG (200.17 vs. 220.80 minutes, P=0.001). No significant differences were observed between the two groups in terms of postoperative hospital stay (9.38 vs. 10.10 days, P=0.426) and surgical complication rate (19.3% vs. 22.9%), including DGE (8.0% vs. 11.8%, P=0.343). Conclusions: The oncological safety and postoperative complications of TLPPG with intracorporeal anastomosis are similar to those of LAPPG with extracorporeal anastomosis.
