Background: Inspiratory muscle training (IMT) has preventive effects against postoperative pulmonary complications (PPCs) after upper abdominal surgery. However, its impact on diaphragmatic function has not been evaluated. This study investigated the effect of preoperative IMT on diaphragmatic excursion (DE) and prevention of PPCs for patients with esophageal cancer., Methods: This study was an unblinded, parallel, randomized controlled trial. Patients with thoracic or abdominal esophageal cancer scheduled for esophagectomy were randomized into the incentive spirometry (IS) or IMT group. During preoperative neoadjuvant chemotherapy, IS or IMT intervention was performed. The inspiratory resistance of the IMT group was consistently set at 50% maximal inspiratory pressure. The primary outcome was the amount of change in DE evaluated with ultrasonography, and the secondary outcome was the incidence of Clavien-Dindo grade II or higher PPCs., Results: This study recruited 42 patients. Among these patients 21 were randomized into the IS or IMT group, and 2 patients dropped out from the study. Finally, 40 patients were included in this analysis. The DE of the IMT group increased significantly after the intervention. The IMT group had significantly larger DE changes than the IS group. Of the 39 patients analyzed for postoperative outcome, 5 experienced grade II PPCs. The IMT group had a lower incidence of PPCs than the IS group., Conclusions: Patients with thoracic and abdominal esophageal cancer scheduled for surgery who had preoperative IMT have increased DE, which may have an important role in prevention of PPCs., (© 2024.

Background: Feeding jejunostomy (FJ) is a common treatment to support patients with esophageal cancer after esophagectomy. However, severe FJ-related complications, such as bowel obstruction, occasionally occur. We investigated the ability of our simple, novel FJ technique, the "curtain method," to prevent bowel obstruction., Methods: In laparoscopic surgery, the main mechanism of bowel obstruction involves torsion of the mesentery accompanied by migration of the intestine across the fixed FJ through the space surrounded by a triangle comprising the ligament of Treitz, fixed FJ, and spleen rather than adhesion. Our "curtain method" involves closure of this triangle zone with omentum, and the appearance of the lifted omentum resembles a curtain. Sixty patients treated with this modified FJ were retrospectively compared with 13 patients treated with conventional FJ in terms of the incidence of bowel obstruction, peritonitis, stoma site infection, and catheter obstruction., Results: From 2013 to 2017, 60 patients underwent esophagectomy and gastric conduit reconstruction accompanied by modified laparoscopic FJ. The median observation period, including the period after tube removal, was 644 days. No FJ-associated bowel obstruction, the prevention of which was the primary aim, occurred in any patient. Likewise, no peritonitis or dislodgement occurred. Eight patients (13%) developed a stoma site infection with granulation. The feeding tube became occluded in 11 patients (18%); however, a new feeding tube was reinserted under fluoroscopy for all of these patients. From 2003 to 2012, 13 patients underwent conventional FJ. The median observation period was 387 days. Three patients (23%) developed bowel obstruction by torsion 71 to 134 days after the first surgery, and all were treated by emergency operations. Other FJ-related complications were not different from those in the modified FJ group., Conclusion: Our simple, novel technique, the "curtain method," for prevention of laparoscopic FJ-associated bowel obstruction after esophagectomy is a safe additional surgery.

Unexpected dysphagia is an important problem affecting life prognosis in patients who have undergone an esophagectomy for esophageal cancer. For nutritional support in patients suffering from dysphagia after a previous esophagectomy, a simplified percutaneous endoscopic transgastric conduit feeding jejunostomy approach was developed that can be performed regardless of the patient's condition. The feasibility of this procedure in 25 patients with esophageal cancer who underwent three-stage esophagectomy with retrosternal gastric conduit reconstruction from April 2009 to December 2016 was evaluated retrospectively. Under fluoroscopy, a percutaneous endoscopic transgastric conduit feeding jejunostomy catheter (9 French) was introduced into the jejunum in the epigastric region using the Seldinger's technique. The following patient data were analyzed retrospectively: operating time, complications, reasons for oral intake difficulty, and clinical data describing patients' nutritional status before and 1 month after percutaneous endoscopic transgastric conduit jejunostomy treatment, such as serum albumin and clinical course. Median patients' age was 68 years (range 50-76 years). Indications for the procedure were late swallowing dysfunction (n = 12), early swallowing dysfunction secondary to surgical complication (n = 8), anastomotic leakage (n = 3), and anorexia (n = 2). Causes of late swallowing dysfunction were radiation injury (n = 8), advanced age (n = 2), or cerebral infarction (n = 2). The median operating time was 29 minutes (range 14-82 minutes). Four patients developed mild erosions at the stoma secondary to bile reflux along the side of the catheter. No patient experienced severe complications such as ileus and peritonitis. Patients were treated for a median of 160 days (range 18-3106 days) with percutaneous endoscopic transgastric conduit jejunostomy. Patient's serum albumin significantly increased from 2.8 to 3.3 g/dl in 1 month. Of the eight patients with early swallowing dysfunction, six successfully regained sufficient oral nutrition after receiving enteral feeding nutritional management. Although all except one late swallowing dysfunction patient could not discontinue tube feeding, five patients were long-term survivors at the time this report was written. This jejunostomy procedure is simple, safe, and useful for patients with unexpected dysphagia and accompanying malnutrition after esophagectomy., (© The Author(s) 2019.

Patients with esophageal cancer are often treated with definitive chemoradiotherapy (dCRT). Regardless of arrival at dCRT, the risk of local/regional recurrence during follow-up is significant. Many patient are faced with limited options for therapy once dCRT has failed. Salvage surgery is the only way for complete cure of patients with local/regional recurrent esophageal cancer after dCRT. However, salvage surgery has a significant high risk of fatal complications. We examine our preventive measures to reduce the incidence of postoperative complications after salvage surgery for thoracic esophageal cancer. The points of our preventive measures are them; I. the ingenuity of surgery, II. the securement of blood supply for the respiratory tract, III. standard lymphadenectomy, IV. countermeasures of anastomotic failure, V. countermeasures of dead space, VI. countermeasures of respiratory complications, VII. perioperative managements. Salvage surgery is a reasonable option to treat patients with local/regional recurrence after failed dCRT. Our preventive mesures are effective, therefore, we have to make the further technological developments and the safety of salvage surgery.

Background/aims: The incidence of delayed gastric emptying after pylorus-preserving pancreaticoduodenectomy has been reported to be 30% to 70%., Methodology: Between January 1996 and December 2002, 43 patients underwent pylorus-preserving pancreaticoduodenectomy, involving pylorotomy, in the First Department of Surgery, Kinki University School of Medicine. The first step in pylorotomy is to cut the duodenal stump obliquely. The next is incision of the pyloric sphincter along its inferior aspect. The incidences of postoperative complications and changes in body weight were collated retrospectively., Results: Delayed gastric emptying was observed in 4 patients (9.3%). However, this complication did not last more than 1 month in any patients. Two patients (4.7%) developed reflux esophagitis 1 month after surgery, but this complication had resolved by 6 months. Weight gain was noted beginning 3 months after surgery., Conclusions: Pylorus-preserving pancreaticoduodenectomy involving pylorotomy may reduce the incidence of delayed gastric emptying and preserve the long-term quality of life more than similar procedures.

Background/aims: Bile leak remains a serious complication after major hepatectomy. The usefulness of external biliary drainage to prevent intraperitoneal bile leak was studied., Methodology: Thirty-nine patients who underwent major hepatectomy from April 1997 through June 2000 were studied. The bile leak test was performed to identify and close leaks following the resection. Patients who still had leakage underwent retrograde transhepatic biliary drainage (RTBD) via a tube inserted through a choledochostomy. Patient's backgrounds, incidence of bile leak, and time until resolution of bile leak were compared between patients who did and did not have an RTBD tube placed., Results: Nineteen patients had an RTBD tube (48.7%). Bile leak developed in 4 patients with the tube (21.1%), and in 4 patients without the tube (20.0%) (not significant). However, the time until resolution of bile leak was 13.3 days for patients with the tube and 51.3 days for patients without the tube (p<0.05). Two patients developed local peritonitis when the tube was removed., Conclusions: Though some patients had bile leakage even with the RTBD tube, use of the RTBD tube decreased the length of time leakage that occurred. RTBD tube drainage should be done routinely with major hepatectomy.
