Abstract

Purpose: The COVID-19 pandemic caused a lockdown in many countries, which induced negative dietary habits and sedentary behavior. Coronavirus Disease 2019 is affecting most countries around the world, including Turkey. In response, all elective surgeries have been postponed. The aim was to evaluate the impact of COVID-19 on obesity-related comorbidities due to morbid obesity surgery delays.

Methods: Retrospective observational case-control study of patients undergoing affiliated University Hospital in Istanbul. The COVID-19 period group was composed of patients operated: from March 1, 2020, to September 1, 2021 (Group A).

The control group was composed of patients operated from January 1, 2018, to March 1, 2020 (Group B). Electronic clinical records were reviewed searching: baseline characteristics, weight and comorbidities evolution, and biochemical values.

Results: A total of 92 patients in the COVID-19 period group and 87 in the pre COVID period group were analyzed. There were no significant differences in baseline characteristics. Most patients were female, 86.93% (12/80) in the COVID-19 period and 83.9% (14/73) in the non-COVID-19 period (p: 0.232), with a mean age of 34.2 years (SD: 12.6) in the COVID-19 period and 33.7 years (SD: 13.5) in the non-COVID-19 period (p: 0.438).

The median BMI was 48.1kg/m² (IQR: 36.59-62.5) for the COVID-19 period and 45.2kg/m² (IQR: 37.3-59.5) for the non-COVID-19 period (p: 0.200).

There was seen increase risk of obesity-related complications in the Covid-19 period.

Conclusion: Delaying morbid obesity surgeries during the COVID-19 pandemic may increase obesity related complications.

Introduction

The COVID-19 is affecting most countries around the world, including Turkey [1,2]. The coronavirus pandemic has had a radical impact on the functioning of healthcare systems worldwide. The health crisis has also brought new challenges to surgical care, including bariatric surgery. In response to the COVID-19 pandemic, a strategy of postponing elective surgery has been adopted by most surgical societies [3]. Bariatric surgery is one of the first disciplines that have largely implemented this strategy. According to The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) recommendations, all elective surgical and endoscopic cases for metabolic and bariatric surgery should be postponed in the interim. Furthermore, clinic and hospital visits are not recommended [4], as other surgical and non-urgent oncological procedures have also been recommended to be cancelled. However, promises to resume procedures at the earliest available date once the pandemic subsides have been offered by the healthcare authorities [5]. The extended waiting lists at surgeries will be another important issue after the pandemic.

Bariatric surgery is the most effective and safe treatment for morbid obesity, particularly when conservative measures of weight management have failed, with established safety and significant regression of obesity-associated diseases such as diabetes and hypertension. Globally, more than 800 000 operations performed from 61 countries have been reported by the International Federation for the Surgery of Obesity and Metabolic Disorders [6].

Though ASA is a common method to determine surgical risk, at first glance it appears to be insufficient to determine the risk of morbid obesity surgery [7]. The ASA guidelines published in 2014 accepted morbidly obese patients with body mass index (BMI) ≥40 as ASA III without examining comorbid diseases. In our study, we aimed to compare the preoperative ASA Scoring system, biochemical parameters and comorbid disease between precovid and during Covid pandemic period.

Methods

Study design

Retrospective observational case-control study: We included all consecutive patients who underwent a Gastric Sleeve gastrectomy for morbid obesity in Istanbul Medeniyet University General Surgery Department. The COVID-19 pandemic and lockdown: from March 1, 20120, to September 1, 2021 COVID-19 period was included in these study. The control group was composed of patients who underwent morbid obesity surgery from October 1, 2018, to March 31, 2019 and were unaffected by the COVID-19 pandemic and lockdown (non-COVID-19 period). Morbid obesity surgery was considered for patients with BMI ≥ 40 kg/m² or morbid obesity with associated comorbidities. All patients were older than 18 years.

Patients with previous bariatric surgery, those who refused the follow-up or who did not attend the routine follow-up visit, were excluded in this study. Routine gastroscopy was performed all of these patients before sleeve gastrectomy for H. Pylori infection and other abnormality as hiatus hernia or something else.

The study was approved by the Turkish Ministry of Health Care Institutional Clinical Research Ethics Committee. NUMBER 27.10.2021/0531.

Operation technic

The operation is performed in reverse Trendelenburg position on an operating table with an angle of 30° and the surgeon takes position between the legs of the patient. Pneumo-peritoneum is performed with the Verses needle in the left upper quadrant. The five-trocar technique is used. The first (10mm) trocar is placed at the upper abdomen 1-2 cm above the umbilicus as an optical trocar. A 5mm trocar is inserted at the sub-xiphoid area for the Nathanson liver retractor. A 15mm trocar is introduced at the right upper quadrant and a 12mm trocar is inserted at the left upper quadrant. Finally, a 5mm trocar is introduced at the left subcostal anterior axillary line. The liver is elevated and this provides adequate visualization of the entire stomach during the gastrectomy. The pylorus of the stomach is then identified and the greater curve of the stomach elevated. An ultrasonic scalpel is then used to enter the greater sac via division of the greater omentum. The greater curvature of the stomach is then dissected free from the omentum and the short gastric blood vessels using the laparoscopic ultrasonic scalpel. The dissection is started 5cm from the pylorus and proceeds to the Angle of His.

An endoscopic linear cutting stapler is used to serially staple and transect the stomach staying just to the left and lateral to the endoscope. The gastrectomy is visualized with the endoscope during the procedure. The transected stomach, which includes the greater curvature, is completely freed and removed from the peritoneum through the left flank port incision (Figure 1).
