Thoracoscopic radical surgery for a morbidly obese patient with early lung cancer after laparoscopic sleeve gastrectomy: a case report

Laparoscopic sleeve gastrectomy as a bridge to colorectal cancer surgery for obese patients: a case report

BACKGROUND

Severe obesity greatly influences the difficulty of colorectal cancer surgery and has been reported to prolong operative time, increase the rate of laparotomy, and elevate increase postoperative complications. We investigated the efficacy of laparoscopic sleeve gastrectomy (LSG) for preoperative weight loss to ensure safe colorectal cancer surgery.

CASE PRESENTATION

A 51 year-old female with a body mass index of 43.5 kg/m2 was referred to our hospital due to a positive fecal occult blood test. She was diagnosed as having a laterally spreading tumor of the cecum by colonoscopy. Endoscopic submucosal dissection was attempted but proved difficult due to the size of the lesion and its proximity to the appendiceal orifice. We planned bariatric surgery prior to colorectal surgery, and she underwent LSG without any complications. Seven months after the LSG, she had lost 30.7 kg, and her final preoperative body mass index was 27.8 kg/m2. Single-incision laparoscopic ileocecal resection was then performed safely. The pathological diagnosis was adenocarcinoma in adenoma of the cecum, TisN0M0.

CONCLUSION

LSG was effective in reducing visceral fat and making it possible to perform safe surgery for colorectal cancer in a severely obese patient.

Agreement between face-to-face and tele-assessment of upper limb disability in lung cancer survivors during COVID-19 era

INTRODUCTION

Upper limb disability can limit the quality of life of lung cancer survivors. The COVID-19 era has required a finding of alternatives to attend the monitoring of presented disturbances with the minor risk of spread. Tele-assessment offers new possibilities for clinical assessment demonstrating good reliability compared to traditional face-to-face assessment in a variety of patients. No previous study has applied this type of assessment in lung cancer survivors. For this reason, the aim of this study was to evaluate the level of agreement between upper limb disability assessment using tele-assessment and the face-to-face method in lung cancer survivors.

METHODS

A reliability study was conducted with 20 lung cancer survivors recruited from the Oncological Radiotherapy Service of the "Hospital PTS" (Granada). Patients attended a session for clinical face-to-face and real-time online tele-assessment. The main outcome measurements of the study included upper limb function (shirt task) and musculoskeletal disturbances (active range of movement and trigger points), and these outcomes were recorded by two independent researchers.

RESULTS

The outcome measures showed good agreement between both assessments. The active range of movement presented heterogeneous results, being excellent reliability (ρ > 0.75) in extension, internal rotation, homolateral adduction, and contralateral abduction, good (0.4 < ρ < 0.75) for flexion, homolateral abduction, contralateral adduction and contralateral external rotation, and poor (ρ < 0.4) for homolateral external rotation. The measure evaluating upper limb function and trigger points show the highest interrater reliability with confidence interval lower limits ≥0.99.

DISCUSSION

The tele-assessment of upper limb function and musculoskeletal disorders of lung cancer survivors present a good interrater reliability compared to face-to-face assessment. It could be useful for monitoring the disability presented by cancer survivors whose access is difficult by the residential situation, physical limitations or the risk of COVID-19 spread.

Effects of serratus anterior plane block and thoracic paravertebral nerve block on analgesia, immune function and serum tumor markers in patients after thoracoscopic radical resection of lung cancer

We aimed to assess the effects of serratus anterior plane block (SAPB) and thoracic paravertebral nerve block (TPVB) on analgesia, immune function and serum tumor markers in patients after thoracoscopic radical resection of lung cancer. A total of 132 patients enrolled from February 2019 to November 2020 were prospectively selected and randomly divided into 3 groups (n=44). Control group received general anesthesia. After induction of general anesthesia, TPVB or SAPB group was given TPVB or SAPB. Their clinical data, operation conditions, Visual Analogue Scale (VAS) score, immune function, serum tumor markers and adverse reactions were compared. TPVB and SAPB groups had lower dosage of sufentanil during operation, later time of first pressing patient-controlled intravenous analgesia (PCA) pump after operation and smaller number of pressing PCA pump within 48 h after operation than those of control group (P<0.05). VAS scores at rest and coughing decreased 6 and 12 h after operation in TPVB and SAPB groups compared with that in control group (P<0.05). Cluster of differentiation 3 (CD3)⁺, CD4⁺ and CD4⁺/CD8⁺ ratio were higher, while CD8⁺ was lower 24 and 48 h after operation in TPVB and SAPB groups than those of control group (P<0.05). TPVB and SAPB groups had lower serum tumor marker levels 24 h after operation than those of control group (P<0.05). The three groups had similar incidence rates of adverse reactions (P>0.05). SAPB and TPVB can markedly improve postoperative analgesic effect, enhance immune function and decrease serum tumor marker levels in patients receiving thoracoscopic radical resection of lung cancer, without increasing adverse reactions. However, TPVB may puncture the pleura.
