Diaphragmatic acute massive herniation after laparoscopic gastroplasty for esophagectomy

Minimally invasive techniques are increasingly being used for oesophagectomy. Diaphragmatic hernia is a rare complication of gastroplasty in open surgery. One of the advantages of the laparoscopic technique, the lack of peritoneal adhesions, may lead to an increased rate of this complication. We report two cases of diaphragmatic acute massive herniation after laparoscopic gastroplasty for esophagectomy out of a series of 44 laparoscopic gastroplasties performed over 33 months. We discuss some technical aspects related to its occurrence. Prevention should include a limited crural division and fixation of the gastric tube to the diaphragmatic crura at primary surgery.

[Complications following oesophagectomy: mechanism, detection, treatment and prevention]

Oesophageal surgery remains a relatively morbid operation with potentially devastating complications that can be minimized by prevention, early recognition, and appropriate management. Anastomotic leak, conduit necrosis, and pulmonary failure are the most serious complications. The management of complications following oesophagectomy is reviewed in the following section.

Caractéristiques des hernies diaphragmatiques après œsophagectomie pour cancer

INTRODUCTION

Diaphragmatic hernia is a rare complication of oesophagectomy for cancer. We report a series of seven patients to determine characteristics of this entity.

PATIENTS AND METHODS

Seven patients (six male and one female, 61 to 68 years old) were operated on for diaphragmatic hernia following oesophagectomy for carcinoma (adenocarcinoma N =4, squamous-cell carcinoma N =3). Oesophagectomy had been performed through abdominal transhiatal approach in four patients and transthoracically in three, with hiatal enlargement in all cases.

RESULTS

Three patients, all symptomatic, underwent emergency surgery within two years following oesophagectomy. Of the four patients operated between two and seven years after oesophagectomy, two were symptomatic. Presence of symptoms were neither related with technique of oesophagectomy, nor to type of hiatal enlargement (anterior, or by crura division). All patients with hernia containing small bowel were symptomatic. All patients were operated through abdominal approach. Hernia contained colon three times, small bowel once, and both three times. Hernia reduction needed additional phrenotomy in six patients. Two patients underwent colectomy to treat peroperative colonic ischemia. Diaphragmatic hiatus was calibrated around the gastric tube by direct suture in six patients or with absorbable mesh in one. There was no death. No recurrences occurred with a follow up ranging from one to five years.

CONCLUSION

The diaphragmatic hernia after oesophagectomy is due to excessive hiatal enlargement. Hernias occurring early after oesophagectomy are badly tolerated and need urgent reoperation. To prevent this complication of oesophagectomy, we advocate calibration of diaphragmatic hiatus fit to width of gastroplasty.
