Background: Internal hernia (IH) is one of the critical complications after gastrectomy with Roux-en-Y reconstruction, which can be prevented by closing mesenteric defects. However, only few studies have investigated the incidence of IH after laparoscopic total gastrectomy (LTG) with Roux-en-Y reconstruction for gastric cancer till date. This study aimed to assess the efficacy of defect closure for the prevention of IH after LTG. Methods: This multicenter, retrospective cohort study collected data from 714 gastric cancer patients who underwent LTG with Rou-en-Y reconstruction between 2010 and 2016 in 13 hospitals. We evaluated the incidence of postoperative IH by comparing closure and non-closure groups of Petersen's defect, jejunojejunostomy mesenteric defect, and transverse mesenteric defect. Results: The closure group for Petersen's defect included 609 cases, while the non-closure group included 105 cases. The incidence of postoperative IH in the closure group for Petersen's defect was significantly lower than it was in the non-closure group (0.5% vs. 4.8%, p < 0.001). The closure group for jejunojejunostomy mesenteric defect included 641 cases, while the non-closure group included 73 cases. The incidence of postoperative IH in the closure group of jejunojejunostomy mesenteric defect was significantly lower than that in the non-closure group (0.8% vs. 4.1%, p = 0.004). Out of 714 patients, 41 underwent retro-colic reconstruction. No patients in the transverse mesenteric defect group developed IH. Conclusion: Mesenteric defect closure after LTG with Roux-en-Y reconstruction may reduce postoperative IH incidence. Endoscopic surgeons should take great care to prevent IH by closing mesenteric defects. [ABSTRACT FROM AUTHOR]

Spontaneous esophageal perforation in Boerhaave's syndrome results in significant morbidity and mortality. The gold standard treatment for this disease is thoracotomy and laparotomy because it can be a life-saving procedure that can be performed in emergencies; however, minimally invasive surgery has recently been reported. This report describes three cases of Boerhaave's syndrome that were treated using laparoscopic transhiatal suture and omental patch. One patient recovered uneventfully and was discharged from the hospital after 12 days. The other 2 patients had postoperative complications, such as minor leakage and remnant abscess (Clavien-Dindo Grade II), but were discharged from the hospital after 17 days and 30 days, respectively. In the case of Boerhaave's syndrome with localized mediastinal collections, a good clinical course can be obtained by laparoscopic transhiatal esophageal repair to avoid surgical invasion due to thoracotomy.

Background: Standardized protocols for laparoscopic surgery of splenic flexure cancer (SFC) have not been established yet. We described a standardized laparoscopic procedure for SFCs and examined its safety and feasibility. Methods: Laparoscopic colectomy for SFC was performed as follows. The sigmoid colon was mobilized to the descending mesocolon through the medial approach. After confirming the base of the inferior mesenteric artery, the left colic artery was dissected and resected at the base. Further dissection was carried out between the mesentery of the colon and the renal fascia until it exceeded the upper pole of the left kidney and the splenic flexure. The next dissection reached the white line at the lateral side and the sigmoid-descending colon junction. After making an incision at the greater omentum and gastrocolic ligament from the center of the transverse colon to the splenic flexure, the transverse mesocolon base was dissected from the inside splenic flexure for complete mobilization. This was performed by approaching from four directions toward the splenic flexure. Intestinal resection and anastomosis are performed. Results: This procedure was performed in 70 patients with splenic flexure colon cancer (mean age 70 years). The mean operative time was 190 minutes, and the mean blood loss was 2.0 mL. No notable perioperative or postoperative complications were noted. Conclusions: Safe mobilization of the splenic flexure can be achieved by approaching from four directions, and standardization of left colectomy can facilitate complete mesenteric excision.

Background: Presently, there is no consensus as to what procedure of intracorporeal esophagojejunostomy (EJS) in totally laparoscopic total gastrectomy (TLTG) is best to reduce postoperative complications. The aim of this study was to demonstrate the superiority of linear stapled reconstruction in terms of anastomotic-related complications for EJS in TLTG.Methods: We collected data on 829 consecutive gastric cancer patients who underwent TLTG reconstructed by the Roux-en-Y method with radical lymphadenectomy between January 2010 and December 2016 in 13 hospitals. The patients were divided into two groups according to reconstruction method and matched by propensity score. Postoperative EJS-related complications were compared between the linear stapler (LS) and the circular stapler (CS) groups.Results: After matching, data from 196 patients in each group were analyzed. The overall incidence of EJS-related complications was significantly lower in the LS group than in the CS group (4.1% vs. 11.7%, p = 0.008). The incidence of EJS anastomotic stenosis during the first year after surgery was significantly lower in the LS group than in the CS group (1.5% vs. 7.1%, p = 0.011). The incidence of EJS bleeding did not differ significantly between the groups, although no bleeding was observed in the LS group (0% vs. 2.0%, p = 0.123). The incidence of EJS leakage did not differ significantly between the groups (2.6% vs. 3.6%, p = 0.771).Conclusion: The use of linear stapled reconstruction is safer than the use of circular stapled reconstruction for intracorporeal EJS in TLTG because of its lower risks of stenosis.

Acute appendicitis is the most common general surgical problem encountered during pregnancy. Laparoscopic appendectomy (LA) is widely accepted as a minimally invasive procedure for acute appendicitis. However, LA during the third trimester is associated with problems, including technical difficulty, risk of preterm delivery, and fetal loss. We successfully managed three cases of LA during the third trimester between 2011 and 2016. None of the cases required conversion to an open procedure, and none of the patients had postoperative complications and/or fetal loss. We reviewed the literature using the PubMED database from 2007 to 2016 to acquire further evidence and identified 6 reports and 17 cases. The conversion rate was 11.8% (2 cases), the complication rate was 6.67% (1 case), and the preterm delivery rate was 20% (3 cases); no fetal loss was observed. Our study and literature review highlights the role of LA as a potentially feasible treatment approach for appendicitis during the third trimester. [ABSTRACT FROM AUTHOR]
