Upside-down stomach - results of mini-invasive surgical therapy

Minimally invasive surgery for large hiatal hernia

The majority of large hiatal hernias are paraesophageal hiatal hernias (PEH). Once prolapse of the stomach to the chest cavity reaches a high degree, it is called an intrathoracic stomach. More than 25 years have elapsed since laparoscopic surgery was carried out as minimally invasive surgery for PEH. The feasibility and safety thereof has nearly been established. PEH may cause serious complications such as strangulation and perforation. The outcome of elective repair of PEH is better than emergent repair, so we should carry out elective repair as much as possible. Although not a major clinical problem, following PEH repair the rate of anatomical recurrence increases with age. In order to reduce the recurrence rate, mesh reinforcement by crural repair has been widely performed. Although this improves the short-term outcomes, the long-term outcomes are unclear. For PEH repair, fundoplication and gastropexy are believed desirable. We should select the procedure associated with a lower incidence of dysphagia and so on following surgery. While relaxing incision is useful for primary tension-free closure, it has not contributed to improvement in the recurrence rate.

Minimally invasive esophagectomy for esophageal cancer - results of surgical therapy

Introduction

The indication for minimally invasive esophagectomy (MIE) in esophageal cancer has an increasing tendency.

Aim

To present our cohort of patients operated on between 2006 and 2012.

Material and methods: A single centre study of 106 consecutive esophagectomies performed for esophageal cancer by a minimally invasive approach in 79 patients was performed. Transhiatal laparoscopic esophagectomy (THLE) was performed in 66 patients, transthoracic esophagectomy (TTE) in 13 patients, with histological findings of squamous cell carcinoma in 28 and adenocarcinoma in 51 patients.

Results

The MIE was completed in 76 (96.2%) patients. In cases of TTE, the operation was converted to an open procedure in 3 cases. Operation time ranged from 225 to 370 min (average 256 min). The number of lymph nodes removed was 7–16 (11 on average). The postoperative course was without any complications in 54 (68.3%) patients. Respiratory complications were observed in 14 (17.7%) patients (9 following THLE, 5 following TTE). Other serious complications included acute myocardial infarction (1 patient) and necrosis of the gastroplasty (1 patient). Anastomotic dehiscence was observed in 8 patients, left recurrent laryngeal nerve paralysis in 8 patients, intra-abdominal abscesses in 2 patients, and pleural empyema in 1 case. The overall morbidity of patients operated on by MIE was 31.6%. Thirty-day mortality was 10.1%.

Conclusions

The MIE belongs to the therapeutic portfolio of surgical procedures performed for esophageal cancer. Successful performance requires erudition of the surgical team in both minimally invasive procedures as well as in classical surgical treatment of esophageal cancer; therefore centralization of patients is imperative.

Radiofrequency ablation in the management of Barrett's esophagus - preliminary own experience

INTRODUCTION

Barrett's esophagus develops as a result of chronic injury of esophagus epithelium from gastroesophageal reflux disease. It is defined when metaplastic columnar epithelium replaces the stratified squamous epithelium which normally lies in the distal esophagus. The condition represents a risk factor for esophageal adenocarcinoma. The aim of the radiofrequency ablation (RFA) method is to destroy metaplastic epithelium with radiofrequency electric current and to stimulate reappearance of the flat multilayer epithelium in the distal esophagus.

AIM

To evaluate the efficiency and safety of the RFA technique, newly introduced in Poland, in the management of Barrett's esophagus.

MATERIAL AND METHODS

Twelve patients were treated with the RFA method. Patients with Barrett's esophagus confirmed in the histopathological report were qualified for treatment. Two RFA techniques were applied using a BARRX(®) device: circular based on the balloon HALO(360) system or focal based on the HALO(90) system mounted to the endoscopic ending. The procedures were performed at 2-month intervals. The macroscopic and microscopic effects of RFA therapy, the patients' treatment tolerance as well as potential complications were evaluated.

RESULTS

In the group of 12 patients subjected to RFA therapy, 10 completed the therapeutic cycle. A total of 37 procedures were performed: 5 HALO(360) and 32 HALO(90). In all patients eradication of the abnormal metaplastic esophageal epithelium was achieved, as confirmed in both endoscopic and histopathological evaluation. In 2 patients with ongoing therapy progressive eradication of metaplastic epithelium was observed. No significant RFA-related complications were reported.

CONCLUSIONS

Based on our preliminary results we consider this method to be promising, free of significant complications and well tolerated by patients. In most patients it results in successful eradication of metaplastic epithelium in the distal esophagus.

Strangulation of the stomach and the transverse colon following laparoscopic esophageal hiatal hernia repair

The authors present a 32-year-old male patient with incarceration of a recurrent esophageal hiatal hernia after laparoscopic repair. A life-threatening strangulation of the stomach and the transverse colon occurred within a few days after the operation. Relapse of hiatal hernias amounts to almost half of early complications characteristic for the laparoscopic approach. General recommendations regarding surgical technique as well as perioperative care have been proposed in order to decrease the risk of relapse. Also, routine contrast radiology on the first or second day following the laparoscopic operation facilitates early diagnosis of relapse of hiatal hernia with emergent reoperation. This may result in decreased morbidity and improved overall outcome of the treatment.
