Single chest drain is not inferior to double chest drain after robotic esophagectomy: a propensity score-matched analysis

Background

Chest drain management has a significant influence on postoperative recovery after robot-assisted minimally invasive esophagectomy (RAMIE). The use of chest drains increases postoperative pain by irritating intercostal nerves and hinders patients from early postoperative mobilization and recovery. To our knowledge, no study has investigated the use of two vs. one intercostal chest drains after RAMIE.

Methods

This retrospective cohort study evaluated patients undergoing elective RAMIE with gastric conduit pull-up and intrathoracic anastomosis. Patients were divided into two groups according to placement of one (11/2020-08/2022) or two (08/2018-11/2020) chest drains. Propensity score matching was performed in a 1:1 ratio, and the incidences of overall and pulmonary complications, drainage-associated re-interventions, radiological diagnostics, analgesic use, and length of hospital stay were compared between single drain and double drain groups.

Results

During the study period, 194 patients underwent RAMIE. Twenty-two patients were included after propensity score matching in the single and double chest drain group, respectively. Time until removal of the last chest drain [postoperative day (POD) 6.7 ± 4.4 vs. POD 9.4 ± 2.7, p = 0.004] and intensive care unit stay (4.2 ± 5.1 days vs. 5.3 ± 3.5 days, p = 0.01) were significantly shorter in the single drain group. Overall and pulmonary complications, drainage-associated events, re-interventions, number of diagnostic imaging, analgesic use, and length of hospital stay were comparable between both groups.

Conclusion

This study is the first to demonstrate the safety of single intercostal chest drain use and, at least, non-inferiority to double chest drains in terms of perioperative complications after RAMIE.

[The suffering surgeon-How do German surgeons protect themselves? : Survey of the German Society of General and Visceral Surgery on the extent of occupational safety measures and health burden among German surgeons]

BACKGROUND

There are few data on how surgeons implement occupational safety measures to protect their own health and how they assess their subjective health burden.

OBJECTIVE

In times of a shortage of surgeons it makes sense to examine these relationships in order to evaluate future-oriented adjustments to increase the attractiveness of the profession of "surgeon".

MATERIAL AND METHODS

An online questionnaire was sent to the registered members of the German Society for General and Visceral Surgery (DGAV) in October 2016. The members were asked about the application of occupational safety measures, individual living conditions, working conditions and the subjective health burden depending on the level of training and type of hospital (basic, standard, maximum care).

RESULTS

The response rate was 21% (1065/5011). Occupational safety measures were not strictly implemented: routine use of dosimeters, thyroid radiation protection, smoke extraction and protective goggles only took place in 40% (427/1065), 39% (411/1065), 10% (104/1065) and 5% (55/1065), respectively. The majority of surgeons (51%, 548/1065) rated their lifestyle as unhealthy. The majority of them are senior physicians, 46% (250/548) consider their job to be a health hazard. The proportion of chief physicians and assistant physicians is only 21% (115/548) and 18% (98/548).

CONCLUSION

Guidelines for standardizing the perioperative protection of German surgeons are desirable. Health-promoting behavior could have a positive effect on the occupational safety of surgeons and ultimately also on patient safety. This can contribute to increasing the attractiveness of the profession "surgeon" in the long term.

Randomized clinical trial of stapler hepatectomy versus LigaSure™ transection in elective hepatic resection

BACKGROUND

Previous studies have demonstrated stapler hepatectomy and use of various energy devices to be safe alternatives to the clamp-crushing technique in elective hepatic resection. In this randomized trial, the effectiveness and safety of stapler hepatectomy were compared with those of parenchymal transection with the LigaSure™ vessel sealing system.

METHOD

Patients scheduled for elective liver resection at two tertiary-care centres were randomized during surgery to stapler hepatectomy or transection with the LigaSure™ device. Total intraoperative blood loss was the primary efficacy endpoint. Transection time, duration of operation, perioperative complications and length of hospital stay were recorded as secondary endpoints.

RESULTS

A total of 138 patients were analysed, 69 in the LigaSure™ and 69 in the stapler hepatectomy group. Baseline characteristics were well balanced between the groups. Mean intraoperative blood loss was significantly higher in the LigaSure™ group than the stapler hepatectomy group: 1101 (95 per cent c.i. 915 to 1287) versus 961 (752 to 1170) ml (P = 0·028). The parenchymal transection time was significantly shorter in the stapler group (P = 0·005), as was the total duration of operation (P = 0·027). Surgical morbidity did not differ between the groups, nor did the grade of complications.

CONCLUSION

Stapler hepatectomy was associated with reduced blood loss and a shorter duration of operation than the LigaSure™ device for parenchymal transection in elective partial hepatectomy. Registration number: NCT01858987 (http://www.clinicaltrials.gov).

Soft tissue sarcomas are characterized by their heterogeneity. With new diagnostic imaging techniques, low- and high-grade components of the tumor can be differentiated. Thus biopsies should be guided by imaging to assure representative specimens. Besides histopathology, the advent of chromosomal and gene expression analysis may allow more accurate classification in the near future. Gene expression profiling has already proven its value by finding new subclassifications in other tumor types. Furthermore, this technique is a promissing tool to predict the response of a tumor to neoadjuvant and adjuvant therapy. Up to now, response evaluation in neoadjuvant therapy is based on tumor size and not on vital tumor cells. Newer techniques (i.e., Magnetic-resonance-Spectroscopy, Molecular Imaging) can show the change of metabolism in neoadjuvant therapy and allow objective, comparative measurement of biological activity. The diagnostic of soft tissue sarcomas implies primarily a multidisciplinary approach for a stage associated therapy.
